abstract = {Some pesticides increase the risk of type 2 diabetes, but whether fetal exposure carries transgenerational risk remains unknown. We evaluated the metabolic effects of gestational exposure to chlorpyrifos and imidacloprid in female Wistar rats and their offspring. We studied female nulliparous Wistar rats, including six exposed to imidacloprid (IMI) and six to chlorpyrifos (CPF) once daily throughout gestation at 1/10 lethal dose 50, while six (control group) received distilled water. These were explored 1 month after the birth of the offspring, while their offspring were explored at weaning (4 weeks) and adult age (12 weeks). Blood glucose, insulin and lipid profile were determined at each stage, while glucose transporter 4 (GLUT4) and nuclear factor kappa beta (NFkβ) protein expression was measured in skeletal muscle at the end of follow up. Exposure to pesticides was associated with significantly higher fasting glucose (+25.4 to 30.9%) and insulin (> 100%) levels, with > 100% increased insulin resistance (HOMA-IR), - 18.3 to - 21.1% reduced HDL-cholesterol and + 60.9 to + 102.6% increased LDL-cholesterol in mothers. GLUT4 expression was reduced by 28.9-42.3% while NFkβ expression increased by 32.8-35.4% in mothers. In offspring, similar abnormalities were observed at weaning (+ 18.4 to 67.4% fasting glucose, + 57.1 to 72.2% LDL-cholesterol, + 72.3 to 78.2% fasting insulin), persisting at adult age with decreased expression of GLUT4 (- 52.8 to 54.5%) and increased expression of NFkβ (+ 30.5 to 30.7%). Gestational exposure to imidacloprid and chlorpyrifos induces hyperglycemia, insulin resistance and dyslipidemia in female Wistar rats and their offspring. The effects on offspring persist until adult age, suggesting intergenerational adverse effects.},

However, little is known about such strategies in the African region where there are higher relative increases in diabetes prevalence. We reported findings from the first 8-month pilot phase of the South African diabetes prevention program. The study was conducted across eight townships (four black and four mixed-ancestry communities) in Cape Town, South Africa, between August 2017 and March 2018. Participants were recruited using both random and self-selected sampling techniques because the former approach proved to be ineffective; <10% of randomly selected individuals consented to participate. Non-laboratory-based diabetes risk screening, using the African diabetes risk score, and based on targeted population specific cut-offs, identified potentially high-risk adults in the community. This was followed by an oral glucose tolerance test (OGTT) to confirm prevalent pre-diabetes. Among the 853 adults without prior diabetes who were screened in the community, 354 (43.4%) were classified as high risk, and 316 presented for further screening. On OGTT, 13.1% had dysglycemia, including 10% with screen-detected diabetes and 67.9% with glycated haemoglobin (HbA1c)-defined high risk. Participants with pre-diabetes (n = 208) had high levels of common cardiovascular risk factors, i.e., obesity (73.7%), elevated total cholesterol (51.9%), and hypertension (29.4%). Self-referral is likely an efficient method for selecting participants for community-based diabetes risk screening in Africa. Post-screening management of individuals with pre-diabetes must include attention to co-morbid cardiovascular risk factors.},

abstract = {Objective The aim of this study was to evaluate the efficacy of capsaicin in inducing significant pain relief in a population of sub-Saharan African type 2 diabetic patients with painful peripheral neuropathy. Design This was a prospective double-blind placebo-controlled randomised clinical trial. Setting A single tertiary-level hospital diabetes center in Yaounde, Cameroon. Participants Twenty-two participants with type 2 diabetes mellitus, presenting with painful diabetic neuropathy, aged 18 years and above. Intervention Participants were equally randomised to capsaicin or placebo. Each drug was to be applied on the lower limbs thrice daily. Follow-up was done every two weeks for eight weeks. Main outcome measure Reduction in the median pain score from baseline, as assessed by the Visual Analogue Scale. Results Twenty-two participants aged 57.5 (50-60) years with a median pain intensity of 6.8 units in the capsaicin group and 5.8 units in the placebo group were included; at inclusion, there was no significant difference in the two groups (p=0.29). After two weeks, the value of pain intensity was 3.3 [2.5-4.0] vs 5.0 [4.0-7.4] (p=0.003); at week four, 3.0 [2.5-3.3] vs 5.0 [4.2-5.5] (p=0,02); at week six, 3.3 [2.5-4.0] vs 4.8 [4.0-6.0] (p=0.03); and at week eight, 6.6 [6.0-7.0] vs 5.2 [5.0-6.0] (p=0.54) for capsaicin and placebo respectively. Conclusion This study, carried out due to a paucity of information on the effect of capsaicin and painful diabetic neuropathy in sub-Saharan African diabetes patients, shows that capsaicin significantly reduces neuropathic pain with worsening after eight weeks of use.

Participating patients had retinal photography sessions using an iPhone 5s (iOS 10.3.3; Apple, Cupertino, CA) coupled to the Make in India Retinal Camera (MIIRetCam; MIIRetCam Inc., Coimbatore, TN, India). Obtained pictures of the retina were stored and transferred via the internet to an ophthalmologist to assess glaucoma. Selected patients were then invited to undergo a conventional ophthalmological examination to confirm the diagnosis. A total of 395 patients were screened, 39 (including 20 women) were diagnosed with suspicion of glaucoma based on retinal photos, a prevalence rate of 9.87%. The following signs were found; Cup/Disc ratio (C/D) ≥0.5 in 64.1% (25/39), asymmetric C/D >0.2 in 35.9% (14/39), papillary haemorrhage in 10.2% (4/39) and retinal nerve fibre deficiency in 2.5% (1/39). Only 14 of 39 patients with suspicion of glaucoma were examined, giving a lost-to-follow-up rate of 64.1%. Chronic open-angle glaucoma was confirmed in 8 patients (true positives) and absent in 6 patients (false positives). The prevalence of smartphone-detected glaucoma and lost-to-follow-up rates were high. So we need to improve this type of screening, with additional tests like transpalpebral applanation tonometer and the smartphone Frequency Doubling Technique visual field combined with better education of patients to increase their adherence to follow-up.},

Methods We carried out an observational retrospective study at the Pediatric Endocrinology Unit of the Mother and Child Centre of the Chantal Biya Foundation in Yaounde, Cameroon from May 2013 to December 2019. All patients diagnosed with a DSD were included, and incomplete files excluded. Results We included 80 patients diagnosed with DSD during the study period. The 46,XX DSD were the most frequent in our study population (n = 41, 51.25%), with congenital adrenal hyperplasia (CAH) as the main diagnosis. The 46,XY DSD accounted for 33.75% and sex chromosome DSD group represented 15% of the study population. Conclusions DSDs are not an exceptional diagnosis in a Sub-Saharan context. 46,XX DSD are the most prevalent diagnosis in our setting. The diagnosis of all these affections is late compared to other centers, justifying advocacy for neonatal screening of DSDs in our context.},

abstract = {BACKGROUND In an era of shifting global agendas and expanded emphasis on non-communicable diseases and injuries along with communicable diseases, sound evidence on trends by cause at the national level is essential. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic scientific assessment of published, publicly available, and contributed data on incidence, prevalence, and mortality for a mutually exclusive and collectively exhaustive list of diseases and injuries. METHODS GBD estimates incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs) due to 369 diseases and injuries, for two sexes, and for 204 countries and territories. Input data were extracted from censuses, household surveys, civil registration and vital statistics, disease registries, health service use, air pollution monitors, satellite imaging, disease notifications, and other sources. Cause-specific death rates and cause fractions were calculated using the Cause of Death Ensemble model and spatiotemporal Gaussian process regression. Cause-specific deaths were adjusted to match the total all-cause deaths calculated as part of the GBD population, fertility, and mortality estimates. Deaths were multiplied by standard life expectancy at each age to calculate YLLs. A Bayesian meta-regression modelling tool, DisMod-MR 2.1, was used to ensure consistency between incidence, prevalence, remission, excess mortality, and cause-specific mortality for most causes. Prevalence estimates were multiplied by disability weights for mutually exclusive sequelae of diseases and injuries to calculate YLDs. We considered results in the context of the Socio-demographic Index (SDI), a composite indicator of income per capita, years of schooling, and fertility rate in females younger than 25 years. Uncertainty intervals (UIs) were generated for every metric using the 25th and 975th ordered 1000 draw values of the posterior distribution. FINDINGS Global health has steadily improved over the past 30 years as measured by age-standardised DALY rates. After taking into account population growth and ageing, the absolute number of DALYs has remained stable. Since 2010, the pace of decline in global age-standardised DALY rates has accelerated in age groups younger than 50 years compared with the 1990-2010 time period, with the greatest annualised rate of decline occurring in the 0-9-year age group. Six infectious diseases were among the top ten causes of DALYs in children younger than 10 years in 2019: lower respiratory infections (ranked second), diarrhoeal diseases (third), malaria (fifth), meningitis (sixth), whooping cough (ninth), and sexually transmitted infections (which, in this age group, is fully accounted for by congenital syphilis; ranked tenth). In adolescents aged 10-24 years, three injury causes were among the top causes of DALYs: road injuries (ranked first), self-harm (third), and interpersonal violence (fifth). Five of the causes that were in the top ten for ages 10-24 years were also in the top ten in the 25-49-year age group: road injuries (ranked first), HIV/AIDS (second), low back pain (fourth), headache disorders (fifth), and depressive disorders (sixth). In 2019, ischaemic heart disease and stroke were the top-ranked causes of DALYs in both the 50-74-year and 75-years-and-older age groups. Since 1990, there has been a marked shift towards a greater proportion of burden due to YLDs from non-communicable diseases and injuries. In 2019, there were 11 countries where non-communicable disease and injury YLDs constituted more than half of all disease burden. Decreases in age-standardised DALY rates have accelerated over the past decade in countries at the lower end of the SDI range, while improvements have started to stagnate or even reverse in countries with higher SDI. INTERPRETATION As disability becomes an increasingly large component of disease burden and a larger component of health expenditure, greater research and development investment is needed to identify new, more effective intervention strategies. With a rapidly ageing global population, the demands on health services to deal with disabling outcomes, which increase with age, will require policy makers to anticipate these changes. The mix of universal and more geographically specific influences on health reinforces the need for regular reporting on population health in detail and by underlying cause to help decision makers to identify success stories of disease control to emulate, as well as opportunities to improve.

abstract = {AIMS The study aimed to identify and describe adverse drug reactions and adherence to clinical guidelines in patients receiving treatment for type 2 diabetes mellitus (T2DM) in Cameroon. METHODS The method used was a cross-sectional study at a tertiary diabetes care service in Yaoundé, Cameroon. Adult T2DM patients attending the diabetes clinic were interviewed using a pre-structured data collection form. Adverse drug reactions (ADRs) were self-reported by the patients. Naranjo's algorithm and Hartwig and Siegel's scale were used for assessment of causality and severity of ADRs, respectively. A blinded senior endocrinologist assessed whether treatment pattern of patients was "adherent" or not to local clinical guidelines for the management of diabetes. RESULTS Of a total of 350 patients enrolled into the study 61.1% were on oral hypoglycaemic agents only, 24.9% were on both oral hypoglycaemic agents and insulin, while 13.4% were on insulin alone. Metformin was used by 96.3% of the patients. Ninety patients reported 101 suspected ADRs. The proportion of ADRs among patients with poor adherence to clinical guidelines was higher than ADRs reported among adherent patients (Chi-square test = 7.3273; p = 0.007). Hypoglycaemia was more frequent ADR among non-adherent (25.7% of the suspected ADR) than adherent participants (11.6%). In the participants whose treatment pattern did not adhere to local clinical guidelines, ADRs were definite in 63.9%, probable in 16.6%, doubtful in 13.9% and possible in 5.6% of the cases. ADRs were moderate in 61.1% and severe in 19.4% of cases whose treatment pattern was non-adherent to clinical guidelines. INTERPRETATION Adverse drug reactions may be frequent in type 2 diabetes patients whose treatment pattern does not adhere to local clinical guidelines in Cameroon. Therefore, the promotion of active pharmacovigilance and the design of training activities to promote the appropriate use of medicines at hospital level in Cameroon could help to improve the management of diabetes and reduce the incidence of avoidable ADRs in the future.},

abstract = {Hyperprolactinemia is responsible for 20 to 25% of consultations of secondary amenorrhea and 17% for female infertility. Dopamine agonists are the gold standard treatment of hyperprolactinemia. Although they are associated with various adverse effects, cabergoline is generally preferred due to better compliance, limited side effects and good therapeutic response. However, bromocriptine is widely and satisfactorily used in a context of limited availability of cabergoline. We sought to describe clinical manifestations of hyperprolactinemia and response to cabergoline in a sub Saharan Africa (SSA) setting. We describe the profile of all patients with a diagnosis of hyperprolactinaemia from 1st July 2012 to 15th May 2014 at the Endocrinology Department of Yaoundé Central Hospital. Patients with physiological hyperprolactinemia were not considered. All patients were routinely started on cabergoline at 0.5mg/week or at 1mg/week in case of macroprolactinoma or desire to become pregnant. The duration of follow up was 8-16 months. After three months of treatment, 8 of 10 patients with amenorrhea had menses and serum prolactin levels decreased significantly at month 2-3 (p = 0.025). In conclusion, our study suggests that cabergoline yields an excellent therapeutic response in a short period of time and may thus be cost saving in sub Saharan context despite its unit price.},

abstract = {We aimed to determine true and false positives of glaucoma screening, relying solely on photos of the retina, taken with a smartphone. We performed a descriptive and analytical study on patients with type 2 diabetes at the National Obesity Centre, Yaoundé, Cameroon. Participating patients had retinal photography sessions using an iPhone 5s (iOS 10.3.3; Apple, Cupertino, CA) coupled to the Make in India Retinal Camera (MIIRetCam; MIIRetCam Inc., Coimbatore, TN, India). Obtained pictures of the retina were stored and transferred via the internet to an ophthalmologist to assess glaucoma. Selected patients were then invited to undergo a conventional ophthalmological examination to confirm the diagnosis. A total of 395 patients were screened, 39 (including 20 women) were diagnosed with suspicion of glaucoma based on retinal photos, a prevalence rate of 9.87%. The following signs were found; Cup/Disc ratio (C/D) ≥0.5 in 64.1% (25/39), asymmetric C/D >0.2 in 35.9% (14/39), papillary haemorrhage in 10.2% (4/39) and retinal nerve fibre deficiency in 2.5% (1/39). Only 14 of 39 patients with suspicion of glaucoma were examined, giving a lost-to-follow-up rate of 64.1%. Chronic open-angle glaucoma was confirmed in 8 patients (true positives) and absent in 6 patients (false positives). The prevalence of smartphone-detected glaucoma and lost-to-follow-up rates were high. So we need to improve this type of screening, with additional tests like transpalpebral applanation tonometer and the smartphone Frequency Doubling Technique visual field combined with better education of patients to increase their adherence to follow-up.},

abstract = {Background . Diabetes is a public health problem worldwide, associated with increased morbidity and mortality. According to the International Diabetes Federation (IDF) 2017 data, around 425 million people worldwide suffer from diabetes. This number is expected to increase to 629 million in 2045. Various occidental studies reported the increased prevalence and lower control of diabetes among prisoners. However, there is no data on the characteristics of inmates with diabetes in sub-Saharan Africa. Methods . A cross-sectional study among incarcerated detainees from the Yaoundé Central Prison was conducted from January to July 2017. Diabetes was defined according to the American Diabetes Association (ADA) criteria. Analyzed variables included phenotypic characteristics, lifestyle, the reason for detention, the sentence severity, and the length of detention. Results . We recruited 437 inmates (344 men) with an average age of 37.0 (95% CI: 35.9-38.3) years. The most frequent age group was 20 to 39 years with 281 (64.7%) inmates, and the mean prison stay was 29.1 (95% CI: 25.7-32.8) months. The prevalence of diabetes in the Yaoundé Central Prison was 9.4%. The main cardiovascular risk factors were a sedentary lifestyle (91.1%), hypertension (39.6%), smoking (31.6%), and alcohol consumption (28.1%). Hypertension ( p = 0.005 ), obesity ( p = 0.0006 ), smoking ( p = 0.04 ), sedentary lifestyle ( p = 0.04 ), major crime ( p = 0.007 ), and minor crime ( p = 0.003 ) were associated with diabetes in univariate analysis. In multivariate analysis, only obesity and sedentary lifestyle were associated with diabetes. Conclusion . Diabetes prevalence in the Yaoundé Central Prison was high, at 9.4%, compared to that in the general population. It was associated with other classical cardiovascular risk factors and factors linked to the sentence (minor and major crimes). This trial is registered with CE00617/CRERSHC/2016.},

abstract = {BACKGROUND Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. METHODS For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5-19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. FINDINGS We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9-10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes-gaining too little height, too much weight for their height compared with children in other countries, or both-occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. INTERPRETATION The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks.

abstract = {Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities1,2. This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity3-6. Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.},

abstract = {BACKROUND AND OBJECTIVE Screening for diabetic retinopathy (DR) is cost-effective when compared with disability loss for those who go blind in the absence of a screening program. We aimed to evaluate the sensitivity and specificity of a smartphone-based device for the screening and detection of DR. PATIENTS AND METHODS A cross-sectional study of 220 patients with diabetes (440 eyes, all patients age 25 years or older) was completed. Tropicamide 0.5% was used for iris dilation followed by an indirect ophthalmoscopy using a 20-D lens. Retinal images were later obtained using a smartphone attached to an adaptable camera device. Retinal images permitted the visualization of the macular and papillary regions and were sent without compression via the internet to a retinal specialist for interpretation. Sensitivity and specificity were calculated for all cases and stages of DR. RESULTS Using our standard examination method, the prevalence of DR and macular edema were 13.6% and 6.4%, respectively. With the smartphone-based retinal camera, the prevalence of DR and macular edema were 18.2% and 8.2%, respectively. Sensitivity and specificity for the detection of all stages of DR was 73.3% and 90.5%, respectively. For the detection of macular edema, sensitivity was 77.8%, and specificity was 95%. For severe nonproliferative DR (NPDR), sensitivity and specificity were 80% and 99%, respectively; for proliferative DR (PDR), they were both 100%. In the early stages of DR, specificity was 89.8% for mild NPDR and 97.1% for moderate NPDR. Sensitivity was 57.1% and 42.9%, respectively. CONCLUSION Screening for DR using a smartphone-based retinal camera has a satisfactory specificity at all DR stages. Its sensitivity seems to be high only in the stages of DR necessitating a specific therapeutic decision (eg, macular edema, severe NPDR, and PDR). A smartphone-based retinal camera may be a useful device to screen for DR in resource-limited settings. [Ophthalmic Surg Lasers Imaging Retina. 2019;50:S18-S22.].},

abstract = {Malaria infection is one of the major causes of deaths in the African continent. The high burden of malaria in Africa is due to P. falciparum, which adapts and cospecializes with Anopheles gambiae, the most effective and widespread malaria vector. Since 2000, the incidence of malaria has been reduced by 17% and malaria mortality rates by 26%. However, the rate of decline has stalled and even reversed in some regions since 2014. In 2017 as described by the latest World malaria report, 219 million malaria cases were reported, up from 2017 million cases reported in 2016 in 91 countries, and the global tally of malaria deaths reached 435,000 deaths, compared with 451,000 estimated deaths in 2016. Despite these achievements, the African region continues to account for about 92% of malaria cases and deaths worldwide. Therefore, it is important to master the current situation of malaria in Africa to see how to better plan its elimination. In this chapter, we present the current situation and prospective means to improve it, including a salutogenesis approach.},

Yet, there is no specific recommendation for human immunodeficiency virus (HIV)-infected women, who are at a known, increased risk of cervical cancer. METHODS A systematic review was performed by searching MEDLINE, EMBASE, and Web of Science for studies published from January 1980 through May 2018. Eligible studies described the prevalence of histologically- and/or cytologically-defined lesions in HIV-infected women at least 6 months post-treatment. The primary endpoint was treatment failure, defined as the presence of residual and/or recurrent high-grade CIN2+/high-grade squamous intraepithelial lesions post-treatment. The pooled prevalence in HIV-infected women and the odds ratios (ORs) for HIV-infected compared to HIV-uninfected women were estimated using random-effects models. RESULTS Among 40 eligible studies, the pooled prevalence of treatment failure in HIV-infected women was 21.4% (95% confidence interval [CI] 15.8-27.0). There was no significant difference in the treatment failure prevalence for cryotherapy (13.9%, 95% CI 6.1-21.6) versus loop electrosurgical excision procedure (13.8%, 95% CI 8.9-18.7; P = .9), but the treatment failure prevalence was significantly higher in women with positive (47.2%, 95% CI 22.0-74.0) than with negative (19.4%, 95% CI 11.8-30.2) excision margin (OR 3.4, 95% CI 1.5-7.7). Treatment failure was significantly increased in HIV-infected versus HIV-uninfected women, both overall (OR 2.7, 95% CI 2.0-3.5) and in all sub-group analyses. CONCLUSIONS There is strong evidence for an increased risk of treatment failure in HIV-infected women, in comparison to their HIV-negative counterparts. The only significant predictor of treatment failure in HIV-infected women was a positive margin status, but further data is needed on long-term outcomes after ablative treatment in HIV-infected women.},

The main concern is considerable rise in morbidity, as shown by increased cardiovascular risk, infertility, osteoporosis and above all, the psychological impact on the life of the patients with hypogonadism. Judicious steroid replacement and culturally-sensitive psychological support before and during steroid therapy remains the key tool in the management of this condition. The present study aimed at filling the knowledge gap on hypogonadism in Cameroon. Methods: we conducted a cross-sectional study over a period of 12 months, in 3 reference hospitals of Cameroon. We included males and females diagnosed with hypogonadism, aged 16 to 50 years and 16 to 45 years respectively. After a complete clinical examination, patients were invited to fill the modified middlesex hospital questionnaire for psychoneurotic evaluation. Results: we recruited 59 patients with a sex ratio of 1:1. The mean age of the females and males were 27.7 ± 9.1years and 30.8 ± 11.7 years respectively. Normosmic Idiopathic Hypogonadotropic Hypogonadism (NIHH) was the most common presentation. Compulsive obsessive traits, phobic anxiety and hysterical trait, were most pronounced in these patients. Testosterone titers significantly correlated positively with testicular size and negatively with body mass index (BMI). A significant positive correlation was found between the testicular volumes measured with ultrasound (US) and with the orchidometer. Conclusion: normosmic idiopathic hypogonadotropic hypogonadism is the most common presentation of hypogonadism in the study population. There is a significant psychosocial impact requiring further investigation and attention.},

Patients and methods A cross-sectional analytical study was conducted in a major hospital in Yaoundé, Cameroon in a cohort of 162 participants (53% females). There were 54 non-obese T2D patients matched for age and sex to 54 obese nondiabetic and 54 nondiabetic lean subjects. PCSK9 level was assessed by sandwich ELISA method and hsCRP by nephelometry. Results PCSK9 and hs-CRP levels were significantly higher in obese and T2D subjects when compared to lean controls (p<0.001 and p=0.002, respectively).

However, in the context of developmental origin of health and disease, putative trans-generational effect of exposure to pesticides are insufficiently studied. We therefore aimed to evaluate the biochemical effect of gestational exposure to four pesticides on female Wistar rats and their offspring at adult age. We studied 30 female nulliparous Wistar rats divided into 5 equal groups. Group 1 served as the control group and received distilled water while group 2, 3, 4 and 5 received orally pesticide 1 (imidacloprid), pesticide 2 (chlorpyrifos), pesticide 3 (imidacloprid + lambda cyhalothrin) and pesticide 4 (oxamyl) respectively once daily throughout gestation at a dose equivalent to 1/10 lethal dose 50. The mothers were followed up until one month post gestation. The offspring were followed up from birth until adult age (12 weeks). In all animals at each time point we evaluated malondialdehyde (MDA), oxidative stress and liver function enzymes. There was similar variation of total body weight in all the groups during and after gestation. However, Female Wistar rats of the exposed groups had significant alterations in liver SOD (-30.8% to +64.1%), catalase (-38.8% to -85.7%) and GSH (-29.2% to -86.5%) and; kidney catalase (> 100%), GSH (> 100%). Moreover, MDA, alanine transaminase (ALT) and aspartate transaminase (AST) levels were significantly higher in pesticide exposed rats compared to the control group. Similar alterations in antioxidant enzymes, MDA and liver function enzymes were observed in offspring of treated rats evidenced at weaning and persisting until adult age. Exposure to pesticides causes oxidative stress and lipid peroxidation in exposed female Wistar rats and their offspring. The persistence in offspring at adult age suggests transgenerational adverse effects.},

We carried out a cross-sectional study including children and adolescents from seven different centers of the Changing Diabetes in Children (CDiC) program. All children enrolled in the program where recruited after parental consent. Diabetes history, daily practice anthropometrics parameters and HbA1c were assessed for each participant. RESULTS We enrolled 95 children adolescents, aged from 06 to 19 years. The mean HbA1c was 9.2 ± 2.5% and 67.4% of participant had poor glycemic control. There was an association between study level of the patients (p = 0.03), healthy eating habits (p < 0.001), diabetes duration (p < 0.001) and level of glycemic control on univariate analysis. On multivariate analysis, diabetes diagnosed for more than 2 years was associated to a good control compared to those with diagnosis that is more recent. Glycemic control of adolescents with type1 diabetes remain very poor in Cameroon despite the implementation of free diabetes care through the program CDiC.},

abstract = {Introduction Hypogonadism refers to a syndrome that results from failure of gonads to function properly. The main concern is considerable rise in morbidity, as shown by increased cardiovascular risk, infertility, osteoporosis and above all, the psychological impact on the life of the patients with hypogonadism. Judicious steroid replacement and culturally-sensitive psychological support before and during steroid therapy remains the key tool in the management of this condition. The present study aimed at filling the knowledge gap on hypogonadism in Cameroon. Methods We conducted a cross-sectional study over a period of 12 months, in 3 reference hospitals of Cameroon. We included males and females diagnosed with hypogonadism, aged 16 to 50 years and 16 to 45 years respectively. After a complete clinical examination, patients were invited to fill the modified middlesex hospital questionnaire for psychoneurotic evaluation. Results We recruited 59 patients with a sex ratio of 1:1. The mean age of the females and males were 27.7 ± 9.1years and 30.8 ± 11.7 years respectively. Normosmic Idiopathic Hypogonadotropic Hypogonadism (NIHH) was the most common presentation. Compulsive obsessive traits, phobic anxiety and hysterical trait, were most pronounced in these patients. Testosterone titers significantly correlated positively with testicular size and negatively with body mass index (BMI). A significant positive correlation was found between the testicular volumes measured with ultrasound (US) and with the orchidometer. Conclusion Normosmic idiopathic hypogonadotropic hypogonadism is the most common presentation of hypogonadism in the study population. There is a significant psychosocial impact requiring further investigation and attention.},

Experts have advocated the use of combination therapies for effective BP control in these patients. The suggested combinations should include a RAAS antagonist and either a CCB or a thiazide diuretic; however, their efficacy is yet to be established in SSA. We investigated the short-term effects of two combination therapies on BP control in SSA type 2 diabetic individuals. This was a double-blinded randomized controlled trial conducted at the Yaoundé Central Hospital (Cameroon) from October 2016 to May 2017. We included type 2 diabetic patients, newly diagnosed for hypertension. After baseline assessment and 24-hour ABPM, participants were allocated to receive either a fixed combination of perindopril + amlodipine or perindopril + indapamide for 42 days. Data analyses followed the intention-to-treat principle. We included fifteen participants (8 being females) in each group. Both combinations provided good circadian BP control after 6 weeks with similar efficacy. Twenty-four-hour SBP dropped from 144 to 145 mm Hg vs 128 to 126 mm Hg with perindopril-amlodipine and perindopril-indapamide, respectively (P = 0.003 for both groups). Twenty-four-hour DBP dropped from 85 to 78 mm Hg (P = 0.013) vs 89 to 79 mm Hg (P = 0.006) in the same respective groups. No significant adverse effect was reported. A fixed initial combination of perindopril-amlodipine or perindopril-indapamide achieved similar effective BP control after 6 weeks in SSA type 2 diabetic individuals with newly diagnosed hypertension. Therefore, these combinations can be used interchangeably in this indication.},

abstract = {PURPOSE OF REVIEW This review seeks to address knowledge gaps around the economic burden of diabetes in Africa. Africa is home to numerous endemic infections and also prevalent non-communicable diseases including diabetes. It is projected that the greatest increases in diabetes prevalence will occur in Africa. The importance of this review therefore lies in providing adequate knowledge on the economic challenges that diabetes poses to the continent and describe the way forward in tackling this epidemic. RECENT FINDINGS Diabetes contributes to a huge amount of the global health expenditure in the world. There is a dearth of information on the economic burden of diabetes in Africa with very limited number of studies in the area. Predictions do show that Africa has the greatest predicted increase in both the burden of diabetes and associated diabetic complications but yet contributes the lowest in the global annual healthcare expenses with regard to diabetes care. In 2017, the International Diabetes Federation (IDF) estimated the total health expenditure due to diabetes at $3.3 billion. In Nigeria, the national annual direct costs of diabetes was estimated in the range of $1.071 billion to $1.639 billion per year while the estimated monthly direct medical costs per individual in Cameroon stands at $148. In Sudan, the direct cost of type 2 diabetes control was $175 per year which only included the cost of medications and ambulatory care. People with diabetes are likely to experience one or more chronic illness and a significant portion of the costs associated with these complications are attributed to the underlying diabetes. The growing epidemics of diabetes and associated diabetic complications worldwide poses catastrophic financial costs, especially in Africa where most of the expenses are paid by patients and families. The most common method used for the estimation of the economic burden of a public health problem like diabetes is the cost-of-illness approach. Cost-of-illness studies traditionally divide costs into three categories: direct, indirect, and intangible. The IDF estimated the total health expenditure due to diabetes at $3.3 billion worldwide in 2017. Most of the existing studies in Africa estimated only the direct costs. The medical direct cost of type 1 diabetes was higher than type 2. However, the estimations of costs of diabetes in many countries in Africa may be underestimated due to absence of data on the relative contribution of cost of diabetes complications.},

abstract = {INTRODUCTION Diabetic cardiac autonomic neuropathy (CAN) is potentially life threatening and its severity might further be aggravated by poor glycaemic control. A decrease in Heart rate variability (HRV) is the earliest finding of CAN even at the sub clinical stage. While intensive glycaemic control prevents the development of CAN in patients with type 1 diabetes, it is not known whether the intensification of glycaemic control using insulin would improve cardiovascular autonomic functions in type 2 diabetes patients. This study aimed to determine the short term effects of optimizing glycaemic control using insulin on the HRV in type 2 diabetes patients. METHODS We conducted a single arm open label clinical trial. Participants were poorly controlled non-insulin treated type 2 diabetes mellitus patients (HbA1c ≥ 7%). The intervention lasted 60 days and consisted in the intensification of glycaemic control through the initiation of a basal plus insulin regimen with titration of insulin to protocol defined glycaemic targets which were; fasting glycaemia: 0.70-1.30 g/L and post prandial glycaemia <1.80 g/L. Long term HRV measurement was done using a 24-h ambulatory electrocardiographic (ECG) recording on day 0 and day 60. Wilcoxon signed rank test was used to compare differences in HRV parameters before and after the intervention. RESULTS A total of 29 (14 males and 15 females) consenting type 2 diabetes mellitus patients without clinical signs of CAN were enrolled and allocated to intervention (14 males and 15 females). The median age was 52 [43-59] years, and duration of diabetes 3.0 [0.6-6.7] years. The intervention induced a reduction in HbA1c from 10.1 [9.1-11.9]% to 6.7 [5.9-6.9]% (p < 0.001) without severe hypoglycaemic events. Concerning HRV parameters, there was a significant improvement in markers of the parasympathetic tone (PNN50: 5.7 [3.6-10.3]% to 8.1 [3.1-16.9]%},

We used a random-effects model to pool data. RESULTS All included studies had a low risk of bias. Six studies were conducted in an urban setting only, one in a rural setting only, and five in both settings. The overall prevalence of diabetes mellitus was 5.8% (95%CI 4.1-7.9; 12 studies) in a pooled sample of 37,147 participants. The prevalence of prediabetes was 7.1% (95%CI: 3.0-21.9; 4 studies) in a pooled sample of 5,872 people. In univariable meta-regression analysis, the prevalence of diabetes mellitus increased with age, hypertension, overweight and obesity. There was no difference for sex and settings (rural versus urban). CONCLUSIONS This study reports a relatively high prevalence of diabetes mellitus and prediabetes in Cameroon, with no difference between urban and rural settings and between sexes. The main drivers include increasing age, overweight and obesity. Community-based educational programs are needed to tackle the burden of the disease in the country.},

This study assessed insulin secretion and insulin sensitivity in human herpesvirus 8 (HHV8)-infected and uninfected sub-Saharan African people with diabetes. METHODS In all, 173 people with non-autoimmune diabetes were enrolled consecutively: 124 with type 2 diabetes mellitus (T2DM) and 49 with ketosis-prone diabetes (KPD) admitted in hyperglycemic crisis. Those with KPD were further subdivided into those with new-onset ketotic-phase KPD (n = 34) or non-ketotic phase KPD (n = 15). All participants were screened for HHV8-specific antibodies and genomic DNA. Blood samples were collected for analysis of fasting glucose, HbA1c, lipid profile, and C-peptide, with insulin resistance and secretion estimated by homeostasis model assessment. RESULTS Among the 173 diabetic participants, 88 (50.9%) were positive for HHV8 antibodies (Ac-HHV8+), including 15 (8.7%) positive for HHV8 DNA (DNA-HHV8+). The seroprevalence of HHV8 was similar between T2DM (55.6%) and KPD (61.2%) subjects. Of those with and without ketotic-phase KPD, 35.3% and 46.7% were Ac-HHV8+, respectively. Body mass index was significantly in lower DNA-HHV8+ than DNA-HHV8- subjects. Low-density lipoprotein and total cholesterol were significantly higher, but C-peptide and homeostatic model assessment of β-cell function (HOMA-β) were significantly lower in DNA-HHV8+ than DNA-HHV8- participants. After excluding DNA-HHV8+ participants, triglyceride concentrations were significantly higher in Ac-HHV8+ (n = 73) than Ac-HHV8- (n = 85) subjects. In contrast, HOMA-β was significantly higher among Ac-HHV8+ than Ac-HHV8- participants. CONCLUSIONS In the present study, HHV8 DNA positivity was associated with low insulin secretion in this sub-Saharan African diabetes population.},

abstract = {BACKGROUND Tobacco use is the leading cause of preventable death in the world today. In 2010, the World Health Organization (WHO) proposed efficient and inexpensive "best buy" interventions for prevention of tobacco use including: tax increases, smoke-free indoor workplaces and public places, bans on tobacco advertising, promotion and sponsorship, and health information and warnings. This paper analyzes the extent to which tobacco use prevention policies in Cameroon align with the WHO tobacco "best buy" interventions. It further explores the context, content, formulation and implementation level of these policies. METHODS This was a case study combining a structured review of 19 government policy documents related to tobacco use and prevention, in-depth interviews with 38 key stakeholders and field observations. The Walt and Gilson's policy analysis triangle was used to describe and interpret the context, content, processes and actors during the formulation and implementation of tobacco prevention and control policies. Direct observations ascertained the level of implementation of some selected policies. RESULTS Twelve out of 19 policies for tobacco use and prevention address the WHO "best buy" interventions. Cameroon policy formulation was driven locally by the social context of non-communicable diseases, and globally by the adoption of the WHO Framework Convention on Tobacco Control. These policies incorporated at a certain level all four domains of tobacco use "best buy" interventions. Formulating policy on smoke-free areas was single-sector oriented, while determining tobacco taxes and health warnings was more complex utilizing multisectoral approaches. The main actors involved were ministerial departments of Health, Education, Finances, Communication and Social Affairs. The level of implementation varied widely from one policy to another and from one region to another. Political will, personal motivation and the existence of formal exchange platforms facilitated policy formulation and implementation, while poor resource allocation and lack of synergy constituted barriers. CONCLUSIONS Despite actions made by the Government, there is no real political will to control tobacco use in Cameroon. Significant shortcomings still exist in developing and/or implementing comprehensive tobacco use and prevention policies. These findings highlight major gaps as well as opportunities that can be harnessed to improve tobacco control in Cameroon.},

Second, the field of Developmental Origins of Health and Disease (DOHaD) has garnered enough compelling evidence demonstrating that early exposures in life affect not only future health, but that the effects of that exposure can be transmitted across generations - necessitating that we begin to focus on prevention. We argue that implementing the SDGs and DOHaD together will be beneficial in several ways; and will require attending to multiple, complex and multidisciplinary approaches as we reach the point of translating science to policy to impact. Here, we begin by providing the context for our work and making the case for a mutually reinforcing, synergistic approach to implementing SDGs and DOHaD, particularly in Africa. To do this, we initiate discussion via an early mapping of some of the overlapping considerations between SDGs and DOHaD.},

abstract = {PURPOSE OF REVIEW This review seeks to address the epidemiology and pathophysiological basis of the interaction between HIV infection and diabetes and the implication for treatment. Its importance stems from the current context of the growing burden of both conditions and the possible mechanisms of interactions that may exist but not yet sufficiently examined. RECENT FINDINGS HIV infection is associated with increased risk of insulin resistance, and ART is associated with metabolic derangement and the occurrence of type 2 diabetes. The increasing survival among people with HIV infection in developing countries is paralleled by a growing burden of chronic non-communicable diseases (NCDs) especially cardiovascular diseases and diabetes mellitus. The prevalence of diabetes mellitus is higher in HIV-positive persons compared to the general population, and especially those with associated hepatitis C virus (HCV) co-infection. Antiretroviral therapy (ART) during chronic HIV infection is the most incriminated risk factor for the development of diabetes mellitus through diverse mechanisms depending on the ART leading to insulin resistance and increased inflammatory status. A staggering 629 million of people 20-79 years are projected to have diabetes by 2045 while the world will soon enter the fourth decade of the HIV infection. Classical risk factors for diabetes such as physical inactivity and unhealthy diet may not solely explain the current trends, suggesting the role of novel risk factors including infections/inflammation. HIV and its treatment have been identified as potential contributors. Co-infections frequently observed during HIV infection also significantly influence both the epidemiological and pathophysiological of the link between HIV and diabetes. Although the relative contribution of each risk factor has not yet been quantified, several lines of evidence suggest that ART is a major contributor to hyperglycemia in HIV infection. ARTs have also led to an increase in metabolic dysfunction, including insulin resistance syndromes, dyslipidemia, and lipodystrophy. The association between ARTs and the risk of developing diabetes therefore calls for a careful choice of medication and evaluation of the risk of developing diabetes.},

Post-stimulatory cortisol was defined as primary endpoint and secondary endpoints include basal cortisol levels, post-stimulatory cortisol increments and the fold increase of cortisol one hour after stimulation. Sickle cell patients had an impairment of adrenal function despite no significant difference between patients' and controls' for basal or post-stimulatory cortisol levels. In fact, one patient in two failed to achieve a two-fold increase in cortisol levels after stimulation (5/10) as opposed to 1 in 10 in the control population (1/10)},

We sought to estimate the lifetime risk of stroke at the regional, country, and global level using data from a comprehensive study of the prevalence of major diseases. METHODS We used the Global Burden of Disease (GBD) Study 2016 estimates of stroke incidence and the competing risks of death from any cause other than stroke to calculate the cumulative lifetime risks of first stroke, ischemic stroke, or hemorrhagic stroke among adults 25 years of age or older. Estimates of the lifetime risks in the years 1990 and 2016 were compared. Countries were categorized into quintiles of the sociodemographic index (SDI) used in the GBD Study, and the risks were compared across quintiles. Comparisons were made with the use of point estimates and uncertainty intervals representing the 2.5th and 97.5th percentiles around the estimate. RESULTS The estimated global lifetime risk of stroke from the age of 25 years onward was 24.9% (95% uncertainty interval, 23.5 to 26.2); the risk among men was 24.7% (95% uncertainty interval, 23.3 to 26.0), and the risk among women was 25.1% (95% uncertainty interval, 23.7 to 26.5). The risk of ischemic stroke was 18.3%, and the risk of hemorrhagic stroke was 8.2%. In high-SDI, high-middle-SDI, and low- SDI countries, the estimated lifetime risk of stroke was 23.5%, 31.1% (highest risk), and 13.2% (lowest risk), respectively; the 95% uncertainty intervals did not overlap between these categories. The highest estimated lifetime risks of stroke according to GBD region were in East Asia (38.8%), Central Europe (31.7%), and Eastern Europe (31.6%), and the lowest risk was in eastern sub-Saharan Africa (11.8%). The mean global lifetime risk of stroke increased from 22.8% in 1990 to 24.9% in 2016, a relative increase of 8.9% (95% uncertainty interval, 6.2 to 11.5); the competing risk of death from any cause other than stroke was considered in this calculation. CONCLUSIONS In 2016, the global lifetime risk of stroke from the age of 25 years onward was approximately 25% among both men and women. There was geographic variation in the lifetime risk of stroke, with the highest risks in East Asia, Central Europe, and Eastern Europe.},

abstract = {Malaria remains one of the major public health concerns in Cameroon. Its treatment is frequently initiated at home, most often with street drugs. The home management of malaria cases entails the prescription of Artemisinin-based combination (ACTs) as first-line therapy for treatment of uncomplicated malaria after having confirmed the malaria case using rapid diagnostic tests. But induced adverse reactions of this therapy are not well known in Cameroon. Thus, a prospective, observational, cohort study of adverse events associated with ACTs was conducted from January 2013 to November 2013 in the health district of Mfou. Children under 5 years receiving ACTs for malaria treatment at home were enrolled. Suspected ADRs and other clinical events were recorded. Data were managed and analysed using Epi Info version 3.5.3 and Statistical Package for Social Sciences, statistical software version 20. Of the 479 children investigated, 56.8% (n=272/479) were males, the age group 25-59 months (49.5%; n=237/479) was most represented, 27.1% (n=130/479) had experienced one form of ADRs, male children (56.2%; n=73/130) and the age group 25-59 months (50.8%; n=66/130) were most affected. No significant association was found between age, sex and incidence of adverse ACTs reactions. The main experienced ACTs reactions were tiredness (43.1%; n=56/130) followed by lack of appetite (24.6%; n=32/130). The incidence ACTs ARDs was found to be relatively low and tolerable. Home management of malaria cases using ACTs should be encouraged and community members should be trained to improve the recognizing and reporting of adverse effects.},

Some factors independent of glucose control could however affect readings during ambulatory monitoring of capillary glucose levels in patients with diabetes mellitus. We sought to evaluate the impact of three body lotions commonly used in Cameroon on different strata of glycaemia. We explored their influence over time on measured capillary glucose values. We enrolled 16 participants. Eligible individuals were adult patients with diabetes (n=12) stratified into three levels of capillary glucose values (100 ± 40 mg/dL [5.55 ± 2.22 mmol/L], 200 ± 40 mg/dL [11.1 ± 2.22 mmol/L] and 300 ± 40 mg/dL [16.65 ± 2.22 mmol/L]) and normoglycaemic individuals (n=4). We measured capillary blood glucose before application, immediately after, then 5, 30 and 60 minutes after application of sweet almond oil, corticosteroid cream and hydroquinone lotion. The measurements made on impregnated body lotion-permeated fingers were compared to that of a clean finger. We observed a significant increase (delta [95% confidence interval, CI]: 119.5% [77.4-222.1]) of capillary glucose level immediately after administration of hydroquinone-containing body lotion (p<0.001). Capillary glucose values after the use of corticoid cream and sweet almond oil was stable 5, 30 and 60 minutes after application (p=0.875 and p=0.883 respectively). In the case of the hydroquinone-containing body lotion, there was a significant difference between capillary glucose level at 5 minutes (delta [95%CI]: 81.6% [55.3-214.2]; p<0.001), 30 minutes (delta [95%CI]: 71.6% [21.8-134.6]; p<0.001) and 60 minutes (delta [95%CI]: 58.3% [2.8-133.3]; p=0.013) after application compared to the value obtained from the clean finger.

We aimed to assess the inflammatory profile in sub-Saharan African patients with KPD during the acute ketotic phase as well as during non-ketotic hyperglycemic crises. Methods We studied 72 patients with non-autoimmune diabetes: 23 with type 2 diabetes mellitus (T2D), and 49 with KPD, all admitted in hyperglycemic crisis (plasma glucose ≥250 mg/dl). The T2D and KPD groups were matched by sex, age, and Body Mass Index. KPD was sub-classified into new-onset ketotic phase (n = 34) or non-ketotic phase (n = 15). We measured TNF-α, MCP-1, MIP1-α, IL-8, MIP1-β, and VEGF in the serum of all participants. Results TNF-α and IL-8 were higher in participants with KPD compared to those with T2D (p = 0.02 TNF-α; p = 0.03 IL-8). TNF-α and IL-8 were also higher in the ketotic phase KPD group compared to the T2D group (p = 0.03 TNF-α; p < 0.001 IL-8) while MIP1-α was lower in people with ketotic phase KPD compared to their T2D counterparts (p = 0.03). MIP1-α was lower in the ketotic phase KPD group compared to the non-ketotic phase KPD group (p = 0.04). MCP-1 was lower in non-ketotic phase KPD compared to T2D (p = 0.04), and IL-8 was higher in non-ketotic phase KPD compared to T2D (p = 0.02). Conclusions Participants with KPD had elevated pro-inflammatory cytokines compared to their T2D counterparts. Ketotic phase KPD is associated with a different pro-inflammatory profile compared to non-ketotic phase KPD, and the inflammatory profile appears to be comparable between non-ketotic phase KPD and T2D patients.},

abstract = {BACKGROUND Tobacco use is the leading cause of preventable death in the world today. In 2010, the World Health Organization (WHO) proposed efficient and inexpensive "best buy" interventions for prevention of tobacco use including: tax increases, smoke-free indoor workplaces and public places, bans on tobacco advertising, promotion and sponsorship, and health information and warnings. This paper analyzes the extent to which tobacco use prevention policies in Cameroon align with the WHO tobacco "best buy" interventions. It further explores the context, content, formulation and implementation level of these policies. METHODS This was a case study combining a structured review of 19 government policy documents related to tobacco use and prevention, in-depth interviews with 38 key stakeholders and field observations. The Walt and Gilson's policy analysis triangle was used to describe and interpret the context, content, processes and actors during the formulation and implementation of tobacco prevention and control policies. Direct observations ascertained the level of implementation of some selected policies. RESULTS Twelve out of 19 policies for tobacco use and prevention address the WHO "best buy" interventions. Cameroon policy formulation was driven locally by the social context of non-communicable diseases, and globally by the adoption of the WHO Framework Convention on Tobacco Control. These policies incorporated at a certain level all four domains of tobacco use "best buy" interventions. Formulating policy on smoke-free areas was single-sector oriented, while determining tobacco taxes and health warnings was more complex utilizing multisectoral approaches. The main actors involved were ministerial departments of Health, Education, Finances, Communication and Social Affairs. The level of implementation varied widely from one policy to another and from one region to another. Political will, personal motivation and the existence of formal exchange platforms facilitated policy formulation and implementation, while poor resource allocation and lack of synergy constituted barriers. CONCLUSIONS Despite actions made by the Government, there is no real political will to control tobacco use in Cameroon. Significant shortcomings still exist in developing and/or implementing comprehensive tobacco use and prevention policies. These findings highlight major gaps as well as opportunities that can be harnessed to improve tobacco control in Cameroon.},

Long term HRV measurement was done using 24 h ambulatory electrocardiographic recording. This automatically provided estimation of HRV using SDNN and RMSSD index, LF, HF, and HF/LF ratio. After baseline investigations, 40 mg of propanolol was given twice a day for 3 days and same parameters were measured after 72 h of treatment. RESULTS Our patients were aged 40 ± 10 years. Propanolol significantly reduced RR and HR interval (669 ms vs 763 ms and 91 vs 79 bpm; p < 0.01). QT and PR space were significantly extended (360 vs 384 ms and 133 vs 172 ms; p = 0.01).

Equally important in diabetes care is the selection of the most appropriate insulin regimen for a particular individual at a specific time. Currently, the choice of insulin regimens for initiation or intensification of therapy is a subjective decision. In this article, we share insights, which will help in rational and objective selection of premixed formulations for initiation and intensification of insulin therapy. The glycemic status and its variations in a person help to identify the most appropriate insulin regimen and formulation for him or her. The evolution of objective glucometric indices has enabled better glycemic monitoring of individuals with diabetes. Management of diabetes has evolved from a ‘glucocentric’ approach to a ‘patient-centered’ approach; patient characteristics, needs, and preferences should be evaluated when considering premixed insulin for treatment of diabetes.

RESULTS Heart rate was significantly higher in patients with thyrotoxicosis (82.91 ± 10.99 vs 67.04 ± 6.80; 0.006) compared to their controls. On time-domain analysis, there was a trend towards reduction in SDNN (39.52 vs. 63.75; p = 0.2) as well as the RMSSD (30.44 vs 64.03; p = 0.09) in patients with hyperthyroidism.

abstract = {INTRODUCTION Pituitary adenomas are benign brain tumours arising from the adenohypophysis; representing 10-15% of all intra-cranial tumours. Despite improved management, they are still related to high morbidity. Visual impairment is a common presentation and visual field defects representing 37-96%. We aimed at describing the clinical presentation of operated patients and their visual outcome. METHODS We conducted a cross-sectional study for 6 months at the Yaoundé Central Hospital's Neurosurgery, Endocrinology and Ophthalmology departments. We included all patients with histopathological confirmation, having pre-operative visual assessment and operated from January 2010 to June 2016. RESULTS Twenty-five participants (50 eyes) were enrolled. Three subtypes of pituitary adenomas were identified: Non-functional pituitary adenomas (64%) > Somatotropinomas (20%) > Prolactinomas (16%). All cases were macroadenomas. The median duration of symptoms was 14 months. All participants presented with vision impairment and 80% with headaches. Craniotomy was used in 88% of cases. The temporal hemifield was the most quantitatively affected; 76% of eyes presented with visual acuity (VA) < 6/12 and 24% of eyes a visual acuity ≥6/12. Thirty percent of eyes presented with optic atrophy; cranial nerve III palsy was the most observed. The Mean deviation (MD), an automated visual field index, improved though non-significant and 16% of eyes had a normal visual field printout after surgery. Left eye mean deviation improved significantly (p = 0.04). After surgery, there was a mild improvement of VA with 62% of eyes having a VA< 6/12 and 38% a VA ≥6/12. There was no ophthalmoplaegia after surgery. Long delay before diagnosis significantly jeopardizes pre-operative and post-operative visual acuity (r = 0.5; p = 0.01). CONCLUSION Quantitative vision parameters comparison are suggestive of a potential improvement of vision. This conclusion will be better ascertained on a large-scale sample size. Long delay before diagnosis is associated to poor visual outcome.},

abstract = {BACKGROUND Tobacco use is the leading cause of preventable death in the world today. In 2010, the World Health Organization (WHO) proposed efficient and inexpensive "best buy" interventions for prevention of tobacco use including: tax increases, smoke-free indoor workplaces and public places, bans on tobacco advertising, promotion and sponsorship, and health information and warnings. This paper analyzes the extent to which tobacco use prevention policies in Cameroon align with the WHO tobacco "best buy" interventions. It further explores the context, content, formulation and implementation level of these policies. METHODS This was a case study combining a structured review of 19 government policy documents related to tobacco use and prevention, in-depth interviews with 38 key stakeholders and field observations. The Walt and Gilson's policy analysis triangle was used to describe and interpret the context, content, processes and actors during the formulation and implementation of tobacco prevention and control policies. Direct observations ascertained the level of implementation of some selected policies. RESULTS Twelve out of 19 policies for tobacco use and prevention address the WHO "best buy" interventions. Cameroon policy formulation was driven locally by the social context of non-communicable diseases, and globally by the adoption of the WHO Framework Convention on Tobacco Control. These policies incorporated at a certain level all four domains of tobacco use "best buy" interventions. Formulating policy on smoke-free areas was single-sector oriented, while determining tobacco taxes and health warnings was more complex utilizing multisectoral approaches. The main actors involved were ministerial departments of Health, Education, Finances, Communication and Social Affairs. The level of implementation varied widely from one policy to another and from one region to another. Political will, personal motivation and the existence of formal exchange platforms facilitated policy formulation and implementation, while poor resource allocation and lack of synergy constituted barriers. CONCLUSIONS Despite actions made by the Government, there is no real political will to control tobacco use in Cameroon. Significant shortcomings still exist in developing and/or implementing comprehensive tobacco use and prevention policies. These findings highlight major gaps as well as opportunities that can be harnessed to improve tobacco control in Cameroon.},

abstract = {Identification of genetic/genomic factors contributing to dyslipidemia is of great interest to prevention and reduction of the onset and burden of cardiovascular diseases in Africa. This systematic review summarizes available data on genetic variants associated with dyslipidemia in populations within Africa. A PubMed and EMBASE database search was conducted to identify all studies published until June 2018 on genetic susceptibility to dyslipidemia in African-based populations, excluding familial hypercholesterolemia. All studies on genetic predispositions of dyslipidemia and respecting the preestablished inclusion criteria were included in this systematic review. Because of high heterogeneity, the data were summarized narratively. Twenty-two studies investigated mostly the targeted genetic variants. A total of 51 polymorphisms in 28 susceptibility genes to dyslipidemia have been associated with a particular trait in the African populations, and through variable effects. Most polymorphisms investigated in Northern Africa seemed to have consistent effects on increasing the level of low-density lipoprotein cholesterol (LDL-C), total cholesterol, and triglycerides in patients with diabetes, myocardial infarction, coronary artery disease, and metabolic syndrome. By contrast, only Ser447Ter and C49620T variants were associated with increased LDL-C in sub-Saharan Africa. Despite few studies available in this context in the literature, certain genetic variants were consistently associated with dyslipidemia especially in Northern Africa as highlighted in this analysis. Further data, particularly from genome-wide association studies, would help establish an African-specific reference for genetic susceptibility markers of dyslipidemia.},
