RESUMO
BACKGROUND/AIMS: With rising elderly populations, age-related health problems such as cognitive impairment and dementia are major public health concerns. We sought to assess the prevalence of cognitive impairment and associated factors in rural elderly Cameroonians. METHODS: The Mini Mental State Examination was used to assess the cognitive function of participants randomly recruited during a house-to-house survey of the Batibo Health District. RESULTS: The prevalence of cognitive impairment in our study was 33.3%. Increasing age, female gender, being single, a lack of formal education, and higher systolic blood pressure values were significantly and independently associated with cognitive impairment. CONCLUSION: The identification of modifiable factors would inform evidence-based policy to decrease the health and social burdens of cognitive impairment and dementia in the elderly in rural Cameroon.

BACKGROUND: Uterine fibroids are the most common uterine tumours in females of reproductive age. During pregnancy, uterine fibroids may be complicated by aseptic necrobiosis. We herein report an ambiguous clinical presentation of uterine fibroids in pregnancy and discuss the diagnostic challenges encountered in our resource-constraint setting. CASE PRESENTATION: A term pregnant Cameroonian woman was admitted to our maternity unit with clinical findings suggestive of a strangulated umbilical hernia. She underwent an emergency caesarean section which fortuitously revealed aseptic necrobiosis of a uterine fibroid, managed within the same surgical intervention by myomectomy. Her post-operative course was uneventful. CONCLUSION: The authors highlight the need for a high index of suspicion by healthcare providers, as well as the need for a multidisciplinary approach for a favourable maternal and foetal outcome.

INTRODUCTION: Snakebite is an important public health concern, especially in tropical areas, but the true burden remains unclear due to sub-optimal reporting and over-reliance on health facility-based data. METHODS: A community-based cross-sectional survey was conducted in Samburu County, Kenya from December 2019 to March 2020. Geospatial techniques were used to create a sampling frame of all households in Samburu County and a multistage cluster sampling strategy to select households and recruit study participants. Five year prevalence and mortality rates were estimated, the characteristics and circumstances of snakebite were described, and multilevel logistic regression models were built to identify independent risk factors for snakebite. RESULTS: We recruited 3,610 individuals living in 875 households from 30 clusters. The 5-year prevalence of snakebite was 2.2% (95% CI 1.4%-3.4%), and the 5-year mortality rate was 138 (95% CI 44-322) deaths per 100,000 inhabitants, resulting in an estimated 1,406 snakebites and 88 deaths from snakebites per year in Samburu County. Snakebite incidents often occurred at night between 9pm and 6 am (44%, n = 36), and the participants were mostly walking/playing outdoors (51%, n = 41) or sleeping (32%, n = 27) when they were bitten. Lower household socioeconomic status and smaller numbers of people per house were significant independent risk factors. CONCLUSION: Samburu County has a high snakebite burden and the most victims are bitten while sleeping or walking outdoors at night. Snakebite prevention and health promotion programs in Samburu County, and other endemic regions, need to be contextualised and consider the geographic, seasonal, and temporal specificities found in our study. Our findings also have implications for health care delivery, especially identification of the need for night-time staffing with expertise in snakebite management and antivenom availability to better manage patients and thereby improve outcomes.

INTRODUCTION: Envenoming by Echis spp. (carpet or saw-scaled vipers) causes haemorrhage and coagulopathy and represents a significant proportion of snakebites in the savannah regions of West Africa. Early diagnosis of envenoming is crucial in the management of these patients and there is limited evidence on the utility of the 20-minute whole blood clotting test (20WBCT) in diagnosing venom-induced consumptive coagulopathy (VICC) following envenoming by Echis ocellatus. METHODS: A prospective observational cohort study was conducted at the Kaltungo General Hospital in North-eastern Nigeria from September 2019 to September 2021. Standardised 20WBCTs were conducted by trained hospital staff and citrated plasma samples were collected at numerous timepoints. Prothrombin time (PT) and international normalised ratio (INR) were determined using a semi-automated analyser and INR values were calculated using international sensitivity indices (ISI). The sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and likelihood ratios of the 20WBCT compared to an INR ≥ 1.4 were calculated, alongside 95% confidence intervals. RESULTS: We enrolled 121 patients into our study, with a median age of 26 (18.0-35.0) years and a male predominance (75.2%). The 20WBCT was positive (abnormal) in 101 out of 121 patients at timepoint 0h, of which 95 had an INR ≥ 1.4, giving a sensitivity of 87.2% (95%CI 79.4-92.8). Among patients with a negative 20WBCT (normal), six had an INR < 1.4 giving a specificity of 50% (95%CI 21.1-78.9). The positive and negative likelihood ratios were 1.7 (95%CI 1.6-1.9) and 0.3 (95%CI 0.1-0.4) respectively. CONCLUSION: The 20WBCT is a simple, cheap, and easily accessible bedside test with a high sensitivity for the detection of patients with venom induced consumptive coagulopathy (VICC) following envenoming by E. ocellatus, although false positives do occur. Repeated 20WBCTs can identify patients with new, persistent, and rebound coagulopathy.

INTRODUCTION: Research on snakebite has mostly been conducted on settled populations and current risk factors and potential interventions are therefore most suited for these populations. There is limited epidemiological data on mobile and nomadic populations, who may have a higher risk of snakebite. METHODS AND RESULTS: We conducted a scoping review to gather evidence on survey methods used in nomadic populations and compared them with contemporary survey methods used for snakebite research. Only 16 (10.5%) of 154 articles reportedly conducted on pastoralist nomadic populations actually involved mobile pastoralists. All articles describing snakebite surveys (n = 18) used multistage cluster designs on population census sampling frames, which would not be appropriate for nomadic populations. We used geospatial techniques and open-source high-resolution satellite images to create a digital sampling frame of 50,707 households and used a multistage sampling strategy to survey nomadic and semi-nomadic populations in Samburu County, Kenya. From a sample of 900 geo-located households, we correctly identified and collected data from 573 (65.4%) households, of which 409 were in their original locations and 164 had moved within 5km of their original locations. We randomly sampled 302 (34.6%) households to replace completely abandoned and untraceable households. CONCLUSION: Highly mobile populations require specific considerations in selecting or creating sampling frames and sampling units for epidemiological research. Snakebite risk has a strong spatial component and using census-based sampling frames would be inappropriate in nomadic populations. We propose using open-source satellite imaging and geographic information systems to improve the conduct of epidemiological research in these populations.

Snakebite envenoming is an acute medical emergency which affects hundreds of thousands of people worldwide, primarily in remote rural areas of low-and middle income countries in the Global South. A considerable proportion of snakebite patients turn to traditional healers (THs) for help, driven by a number of push and pull factors. These include socio-cultural factors, geographical proximity, and the absence or inaccessibility of overstretched and often costly allopathic healthcare services. Although traditional healers and allopathic healthcare staff share a common focus -the recovery and well-being of their patients- both systems operate largely in parallel to each other with collaborations being an exception rather than the rule. This is to the detriment of snakebite patients, who frequently find themselves being caught-up in the dualism between the two separate systems. Given the right circumstances, snakebite patients could benefit from elements of care from both modalities. Here, we have reviewed the role of THs in snakebite care and explored how their integration into the formal healthcare system could improve the implementation and outcome of care. The effective recruitment of THs to aid in disease control and treatment efforts in diseases other than snakebite underscores the potential benefits of this strategy. Carefully devised proof of concept studies are needed to test our hypothesis that collaborations between the formal healthcare sector and THs are feasible and improve outcomes in snakebite care.
RESUMO
BACKGROUND: Infertility, and fertility treatment, are associated with psychological distress that may influence subsequent mental health including postpartum depression and anxiety. METHODS: Data for women who had a livebirth between 1991 and 2013 were drawn from the Clinical Practice Research Datalink. Conception history prior to their first recorded birth was categorised as 'no fertility problems', 'untreated subfertility', ovulation induction (OI), and assisted reproductive technologies (ART). Depression and/or anxiety in the 12 months postpartum were identified using records of diagnoses, symptoms, and prescriptions. Prevalence was compared, and odds ratios estimated using multivariable logistic regression. RESULTS: Of 235,127 mothers, 31,947 (13.6%) had evidence of postpartum depression and/or anxiety. Mothers in the ART group had 22% lower odds of postnatal depression and/or anxiety compared to mothers in the fertile group (OR 0.78; 95% CI [0.70-0.86]; p < 0.0001). Accounting for prior mental health, lifestyle, sociodemographic and pregnancy-related factors reduced the strength of the association (aOR 0.87; 95% CI [0.78-0.97]; p = 0.01). There were no significant associations observed in the untreated subfertility or OI groups. LIMITATIONS: As in any analysis of routine data, the quality of recording is important and some information was unavailable (e.g. education, social support). CONCLUSIONS: Women with a history of subfertility, OI or ART treatment were not at increased risk of postpartum depression and/or anxiety compared to those with no fertility problems. It is important to explore whether women who underwent ART are less likely to experience depression/anxiety or do not seek help when needed, with implications for their health and care.

INTRODUCTION: Human-snake interactions are common in tropical regions where subsistence-farming and livestock-herding activities predominate alongside proliferation of snakes. Local beliefs and perceptions about snakes and snakebites influence human behaviour. Understanding these beliefs and perceptions can inform the development of resources to drive behaviour change and to minimise the risk of injury to both humans and snakes. This qualitative study, conducted between May and July 2019, sought to explore the beliefs and perceptions regarding snakes and snakebites, and methods of prevention and management among members of the community in Kitui County, Kenya. METHODS: Semi-structured interviews were used to collect qualitative data from 23 participants, recruited using a stratified purposeful sampling strategy in four selected sub-counties of Kitui county. Interview data was anonymised and coded and a thematic analysis was conducted using NVivo 12. RESULTS: People from Kitui county mostly had negative perceptions about snakes. There was a generalised awareness of the need to prevent snakebite, predominantly through keeping snakes away from homes/compounds. However, implementation was limited by financial constraints. Participants also identified logistic and financial obstacles to early hospital presentation following a snakebite, and they expressed a strong preference of having their snakebites treated in a hospital over consulting traditional healers. There was a universal recognition of the benefit of early intervention with a specific appreciation of the utility of the black stone. Furthermore, the removal of a snake's "teeth" was an expected treatment outcome for some community members, with the failure to do so perceived as causing poor wound healing or persistence of symptoms. Some religious groups held views which differed from most participants. CONCLUSION: There is a need to explore and clarify common misconceptions about snakes and first aid treatment of snakebites, encourage learning about the true nature of snakes, and highlight beneficial uses of snakes. A change in the epistemological conception of community education material by enhancing the value and use of local forms of knowledge, and the employment of art techniques to transmit this knowledge, could improve community perception and methods of snakebite prevention. Patient expectations should be appropriately managed by discussing possible outcomes, incorporating follow-up visits and addressing long-term complications of snakebites.

OBJECTIVES: This study aimed to estimate the prevalence of atrial fibrillation (AF) in adults with heart failure (HF) and summarise the all-cause mortality ratio among adult patients with coexisting HF and AF in sub-Saharan Africa (SSA). SETTING: This was a systematic review and meta-analysis of cross-sectional and cohort studies with primary data on the prevalence and incidence of AF among patients with HF and the all-cause mortality ratio among patients with HF and AF in SSA. We combined text words and MeSH terms to search MEDLINE, PubMed and Global Health Library through Ovid SP, African Journals Online and African Index Medicus from database inception to 10 November 2021. Random-effects meta-analysis was used to estimate pooled prevalence. PRIMARY OUTCOME MEASURES: The prevalence and incidence of AF among patients with HF, and the all-cause mortality ratio among patients with HF and AF. RESULTS: Twenty-seven of the 1902 records retrieved from database searches were included in the review, totalling 9987 patients with HF. The pooled prevalence of AF among patients with HF was 15.6% (95% CI 12.0% to 19.6%). At six months, the all-cause mortality was 18.4% (95% CI 13.1% to 23.6%) in a multinational registry and 67.7% (95% CI 51.1% to 74.3%) in one study in Tanzania. The one-year mortality was 48.6% (95% CI 32.5% to 64.7%) in a study in the Democratic Republic of Congo. We did not find any study reporting the incidence of AF in HF. CONCLUSION: AF is common among patients with HF in SSA, and patients with AF and HF have poor survival. There is an urgent need for large-scale population-based prospective data to reliably estimate the prevalence, incidence and risk of mortality of AF among HF patients in SSA to better understand the burden of AF in patients with HF in the region.

AIMS: Better knowledge of the global metabolic syndrome (MetS) prevalence and its components is a prerequisite to curb the related burden. METHODS: We systematically searched PubMed, EMBASE, Web of Knowledge, Africa Journal Online, Global Index Medicus up to May 23, 2021. Prevalence pooling was done with a random-effects meta-analysis. RESULTS: In total, 1,129 prevalence data (28,193,768 participants) were included. The MetS global prevalence varied from 12.5% (95 %CI: 10.2-15.0) to 31.4% (29.8-33.0) according to the definition considered. The prevalence was significantly higher in Eastern Mediterranean Region and Americas and increased with country's level of income. The global prevalence was 45.1% (95 %CI: 42.1-48.2) for ethnic-specific central obesity, 42.6% (40.3-44.9) for systolic blood pressure (BP) ≥ 130 mmHg and/or diastolic BP ≥ 85 mmHg, 40.2% (37.8-42.5) for HDL-cholesterol < 1.03 for men or < 1.29 mmol/L for women, 28.9% (27.4-30.5) for serum triglycerides ≥ 1.7 mmol/L, and 24.5% (22.5-26.6) for fasting plasma glucose ≥ 5.6 mmol/L. CONCLUSIONS: This study reveals that MetS and its related cardiometabolic components are highly prevalent worldwide. This study calls for more aggressive and contextualized public health interventions to tackle these conditions.

BACKGROUND: Adverse reactions to antivenom considerably complicate the clinical management of snakebite envenomed patients because it necessitates a temporary suspension of life-saving antivenom, increases costs and can compromise patient outcomes. This study sought to explore the association between cattle-herding occupation and ethnic group and the occurrence of early adverse reactions to antivenom. METHODS: This cross-sectional study was conducted between the 25th April and 11th July 2011 at the Kaltungo General Hospital in north east Nigeria. The exposure variable of cattle-herding occupation showed a strong correlation with the ethnic group variable, thus these were combined into a new variable with three categories (Fulani and herder, either Fulani or herder, and neither Fulani nor herder). The outcome variable was the occurrence of early adverse reactions, defined as any new symptoms occurring within 6 hours of antivenom administration. Odds Ratios were estimated using multivariable logistic regression models controlling for potential confounders. RESULTS: Among 231 envenomed snakebite victims, the overall incidence of early adverse reactions was 11.9% (95% confidence intervals: 8.0-16.9%). Patients who were Fulani and herders had a higher incidence of early adverse reactions compared to patients who were neither Fulani nor herders (20% vs 5.7%). After adjusting for age and gender, victims who were Fulani and herders were 5.9 times more likely to have an early adverse reaction, compared to victims who were neither Fulani nor herders (95% CI: 1.88-18.59; p = 0.002). INTERPRETATION: To the best of our knowledge, this is the first study to provide evidence of higher odds of early adverse reactions among patients from a particular occupation and/or ethnic group. We recommend that snake envenomed patients of Fulani origin be especially closely monitored for adverse reactions, that hospitals receiving these patients be appropriately resourced to manage both envenoming and adverse reactions and that premedication with adrenaline should be considered. Our findings provide an argument for speculation on the influence of immunological or lifestyle-related differences on the occurrence of early adverse reactions to antivenom.

BACKGROUND: Programs that integrate tuberculosis (TB) and human immunodeficiency virus (HIV) treatment aim to provide efficient treatment services and maximize successful treatment outcomes through the delivery of both TB and HIV treatment by one provider at the same time and location. However, multi-drug resistant tuberculosis (MDR-TB) is more difficult to treat as compared to drug-sensitive TB, and in low- and middle-income countries (LMICs), the potential of programs integrating TB/HIV treatment to sustain favourable MDR-TB treatment outcomes is poorly elucidated. The objective of this review is to perform a systematic collection, critical appraisal and synthesis of existing evidence on therapeutic outcomes of MDR-TB and their predictors among adults receiving integrated treatment for TB/HIV in LMICs. METHODS: A systematic review of quantitative evidence from observational cohort studies will be performed. MEDLINE, Embase, and Global Health electronic databases will be searched for relevant studies published from March 2004 to December 2019. Two investigators will independently screen the search output, review the eligible studies, and assess the quality of the eligible studies using quality assessment tools of the National Heart Lung and Blood Institute. Random-effects meta-analysis will be used to obtain summary estimates. Heterogeneity across studies will be assessed using the I2 statistic. The confidence in the summary estimates will be rated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. The final review will be reported following the guidelines of the Preferred Reporting System for Systematic Reviews and Meta-analysis, presented at scientific conferences and published in a peer-reviewed journal. DISCUSSION: This study is expected to report the performance of integrated TB/HIV treatment programs as regards their potential to uphold successful MDR-TB treatment outcomes in LMICs. Furthermore, the review will indicate patient-related and healthcare-related factors that should be addressed to improve on survival of patients with MDR-TB/HIV co-infection in LMICs. SYSTEMATIC REVIEW REGISTRATION: This review has been registered with the International Prospective Register of Systematic Reviews and the reference ID is CRD42020159745.

INTRODUCTION: Attention deficit hyperactivity disorder (ADHD) is a chronic mental disorder that is associated with poor productivity, with a significant impact on the quality of life. OBJECTIVES: To determine factors associated with symptoms of ADHD among medical students in Cameroon. DESIGN: A web-based cross-sectional study. SETTING: Participants were recruited through a social media platform, WhatsApp, from 24 June to 2 September 2018. PARTICIPANTS: Medical students aged 18 years and older from seven medical schools in Cameroon. All non-medical students and all medical residents were excluded. RESULTS: Data from a total of 491 eligible participants were analysed. The median age was 25 (IQR 21-25) years and 54% were of the participants were female. The prevalence of self-reported symptoms of ADHD was 24.4% (95% CI 20.6% to 28.3%). Histories of chronic disease (adjusted OR (AOR) 2.96; 95% CI 1.49 to 5.86, p=0.002), family history of ADHD (AOR 3.38; 95% CI 1.04 to 10.44, p=0.035), severe depression (AOR=3.49; 95% CI 1.82 to 6.77, p<0.001) and anxiety disorder (AOR 2.06; 95% CI 1.25 to 3.36, p=0.004) were found to be independently associated with the symptoms of ADHD. CONCLUSION: ADHD may be a highly prevalent mental disorder among medical students, and is associated with severe depression, anxiety disorders and chronic diseases. There is a need to conduct a large-scale prospective cohort study with interviews to estimate the true prevalence and incidence of ADHD among medical students in Cameroon, and to determinant the risk factors associated with the disorder.

BACKGROUND: Cryptorchidism is the most common congenital malformation of the male genitourinary tract. The cryptorchid testis is most often located in the inguinal canal; however, intra-abdominal locations are not rare. The risk of malignancy in an undescended testis is 10% with the highest risk in an intra-abdominal testis. CASE PRESENTATION: Here we describe a case of a 40-year-old fertile man of Fulbe origin who presented with a non-tender lower abdominal mass of 2 months' duration. A scrotal examination revealed just one testis in the right scrotum, with the contralateral scrotum and inguinal canal being empty. An exploratory laparotomy followed by tumor excision and histopathology revealed a testicular seminoma. CONCLUSION: This case report highlights the need for routine scrotal examination in all men presenting with an abdominal mass so as to rule out the possibility of an intra-abdominal seminoma.

INTRODUCTION: Heart failure (HF) remains a major non-communicable disease in sub-Saharan Africa (SSA) associated with high rates of readmission, mortality and loss of economic productivity as it affects mostly young and economically active adults. Atrial fibrillation (AFib) is a major determinant of mortality among patients with HF in SSA. Meanwhile, the use of anti-arrhythmic medications in the region remains unacceptably low. This review aims to evaluate the prevalence and incidence of AFib in adult patients with HF in SSA, and the all-cause mortality rate among patients with HF and AFib. METHODS AND ANALYSIS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Protocols 2015 statement was used to prepare this protocol. All eligible studies from database inception to December, 31 2018 in MEDLINE, Embase, Google Scholar, Web of science and Africa-specific databases (AFROLIB, African Index Medicus and African Journals Online) will be included without language restrictions. The process of study screening, selection, data extraction and assessment of risk of bias will be conducted independently by two reviewers. Disagreements will be arbitrated by a third reviewer. Study-specific estimates will be pooled using random-effect meta-analysis and summary measures obtained will be presented in forest plots. The χ2 test on Cochrane's Q and the I2 statistics will be used to assess and quantify heterogeneity, respectively. The Egger's test and funnel plots will be used to assess publication bias. ETHICS AND DISSEMINATION: Since our review will be based on already published data, an ethical approval is not required. The findings of this review will be presented in conferences and peer-reviewed journals and shared on social media such as Researchgate, Facebook, WhatsApp and Twitter. PROSPERO REGISTRATION NUMBER: CRD42018087564.

BACKGROUND: Septic shock is a life-threatening infection frequently responsible for hospital admissions or may be acquired as nosocomial infection in hospitalized patients with resultant significant morbidity and mortality . There is a dearth of data on a résumé and meta-analysis on the global epidemiology of this potentially deadly condition. Therefore, we propose the first systematic review to synthesize existing data on the global incidence, prevalence and case fatality rate of septic shock worldwide. METHODS: We will include cross-sectional, case-control and cohort studies reporting on the incidence, and case fatality rate of septic shock. Electronic databases including PubMed, Embase, WHO Global Health Library and Web of Science will be searched for relevant records published between 1 January 2000 and 31 August 2019. Independents reviewers will perform study selection and data extraction, as well as assessment of methodological quality of included studies. Appropriate meta-analysis will then be used to pool studies judged to be clinically homogenous. Egger's test and funnel plots will be used to detect publication bias. Findings will be reported and compared by human development level of countries. ETHICS AND DISSEMINATION: Being a review, ethical approval is not required as it was obtained in the primary study which will make up the review. This review is expected to provide relevant data to help in evaluating the burden of septic shock in the general population. The overall findings of this research will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42019129783.

BACKGROUND: Cutaneous larva migrans is a neglected zoonotic helminthic disease which is paradoxically underreported in low-income and middle-income countries from where a majority of the cases emanate. It presents as migratory, raised, erythematous serpentine lesions, responsive to treatment with antihelminthics. It is common in children, but rare in babies. We report an unusual case of cutaneous larva migrans in a Cameroonian baby. CASE PRESENTATION: We report the case of a 9-month-old Cameroonian baby girl, whose mother had the habit of drying the child's clothes on the grass in her courtyard. The child was brought to our hospital after she developed itchy, snake-like, slowly progressing lesions on her abdomen and chest. An examination revealed multiple raised serpentine and erythematous skin lesions consistent with cutaneous larva migrans which subsided on antihelminthic and antihistaminic therapy. CONCLUSIONS: Cutaneous larva migrans is an endemic disease with predilection for poor and vulnerable persons. Preventive efforts such as wearing of slippers, usage of drying lines, and deworming of pets are crucial in preventing the occurrence of this disease and should be encouraged.

OBJECTIVE: To summarise available data on the risk factors, complications and the factors associated with complications of lower limb cellulitis in Africa. METHODS: We did electronic searches on PubMed, EMBASE, Scopus and African Journals Online from 1 January 1986 to 30 October 2017, extracted and summarised data on the risk factors, complications and the factors associated with the complications of lower limb cellulitis from eligible literature. RESULTS: A total of seven studies were retained for final review after the search and screening processes. Local risk factors of cellulitis reported were: disruption of the skin barrier, neglected wounds, toe-web intertrigo, leg ulcers, use of depigmentation drugs and leg oedema. Obesity was the only reported general risk factor of cellulitis. Five studies reported on the complications of cellulitis which included: abscess formation, necrotising fasciitis, bullae, haemorrhagic lesions, necrosis, phlebitis and amputations. Nicotine addiction, chronic use of non-steroidal anti-inflammatory drugs, delay in the initiation of antibiotic treatment and elevated erythrocyte sedimentation rate were risk factors of complications of lower limb cellulitis identified from three studies. CONCLUSION: This review highlights the important role of local risk factors in the pathogenesis of lower limb cellulitis in Africa. The association between voluntary skin depigmentation and lower limb cellulitis should alert public health authorities and the general population to the health risks associated with this practice. The identification and improved management of the risk factors of lower limb cellulitis and its complications could go a long way in decreasing the morbidity and health costs incurred by lower limb cellulitis in Africa.

INTRODUCTION: HIV testing is an invaluable entry point to prevention, care and treatment services for people living with HIV and AIDS. Poor adherence to recommended protocols and guidelines reduces the performance of rapid diagnostic tests, leading to misdiagnosis and poor estimation of HIV seroprevalence. This study seeks to evaluate the adherence of primary healthcare facilities in Cameroon to recommended HIV counselling and testing (HCT) procedures and the impact this may have on the reliability of HIV test results. METHODS AND ANALYSIS: This will be an analytical cross-sectional study involving primary healthcare facilities from all the 10 regions of Cameroon, selected by a multistaged random sampling of primary care facilities in each region. The study will last for 9 months. A structured questionnaire will be used to collect general information concerning the health facility, laboratory and other departments involved in the HCT process. The investigators will directly observe at least 10 HIV testing processes in each facility and fill out the checklist accordingly. ETHICS AND DISSEMINATION: Clearance has been obtained from the National Ethical Committee to carry out the study. Informed consent will be sought from the patients to observe the HIV testing process. The final study will be published in a peer-reviewed journal and the findings presented to health policy-makers and the general public.

Mortality rate among critically ill patients admitted to the Intensive Care Unit is high, particularly in low-income countries (LIC). Many scores have been developed to predict these fatal outcomes. In LIC, the applicability of scoring systems is precluded by the unavailability of resources to compile all the parameters of these scores. Herein, we highlight the advantages of two models: the Modified Early Warning Score (MEWS) and the Rapid Emergency Medical Score (REMS). The REMS and the MEWS have the advantage of being accurate, simple, inexpensive, and practical for LIC.
