User fee exemption and malaria treatment-seeking for children under five in a Cameroonian health district: a cross-sectional study.

BACKGROUND: In Cameroon, malaria contributes significantly to the morbidity and mortality of children under 5 years old. In order to encourage adequate treatment-seeking in health facilities, user fee exemptions for malaria treatment have been instituted. However, many children are still brought to health facilities in the late stage of severe malaria. This study sought to determine the factors affecting the hospital treatment-seeking time of guardians of children under 5 years within the context of this user fee exemption. METHODS: This was a cross-sectional study conducted at three randomly selected health facilities of the Buea Health District. A pre-tested questionnaire was used to collect data on the treatment-seeking behaviour and time of guardians, as well as potential predictors of this time. Hospital treatment sought after 24 h of noticing symptoms was denoted as delayed. Continuous variables were described using medians while categorical variables were described using percentages. A multivariate regression analysis was used to determine the factors affecting malaria treatment-seeking time of guardians. All statistical tests were done at a 95% confidence interval. RESULTS: Most of the guardians made use of pre-hospital treatments, with self-medication being practiced by 39.7% (95% CI 35.1-44.3%) of them. A total of 193 (49.5%) guardians delayed seeking treatment at health facilities. Reasons for delay included financial constraints and watchful waiting at home, during which guardians waited and hoped their child could get better without requiring medicines. Guardians with estimated monthly household incomes denoted as low/middle were significantly more likely (AOR 3.794; 95% CI 2.125-6.774) to delay seeking hospital treatment. The occupation of guardians was another significant determinant of treatment-seeking time (AOR 0.042; 95% CI 0.003-0.607). Also, guardians with tertiary education were less likely (AOR 0.315; 95% CI 0.107-0.927) to delay seeking hospital treatment. CONCLUSIONS: This study suggests that despite user fee exemption, other factors such as educational and income levels of guardians affect malaria treatment-seeking time for children aged under five. Therefore, these factors should be considered when enacting policies aimed at increasing access of children to health facilities.

Prevalence and associated factors of non-medical use of prescription drugs among adolescents in secondary schools in Buea, Cameroon: a cross-sectional study.

BACKGROUND: The non-medical use of prescription drugs is a growing public health problem worldwide. Recent trends in Cameroon show that the use of psychoactive substances, among which are prescription drugs by adolescents is becoming a public health issue and is linked to juvenile delinquency and violence in schools. However, there is a paucity of data on the burden of this phenomenon among adolescent secondary school students in the country. The aim of this study was to determine the prevalence and factors associated with the use of non-prescription drugs in secondary schools in Buea, South West region of Cameroon. METHODS: We conducted a cross-sectional study from 1st February 2021 to 30th April 2021. Secondary school students were recruited using a multistage stratified cluster sampling. A modified and standardized version of the World Health Organization student drug-use survey model questionnaire was used. Ethical approval was obtained from the Institutional Review Board of the Faculty of Health Sciences, University of Buea (No. 2021/1273-02/UB/SG/IRB/FHS). The Statistical Package for Social Sciences, IBM SPSS Statistics for Windows, Version 25.0. was used for data analysis. Descriptive statistics were used to describe the sociodemographic characteristics of participants. Univariate and multivariate logistic regression models were used to explore associated factors of non-medical use of prescription drugs. RESULTS: A total of 570 participants were enrolled for the study, and 510 participants responded giving a response rate of 89.5%. The prevalence of non-medical use of prescription drugs was 15.3%, tramadol being the most used. Motivators for non-medical use of prescription drugs were "to work longer", "to be courageous", and "curiosity". Logistic regression results showed that alcohol consumption [OR 3.68; 95% CI: 2.24-6.06; p < 0.001], smoking [OR 6.00; 95% CI: 3.07-11.75; p < 0.001] and use of illicit drugs [OR 10.85; 95% CI: 5.48-21.48; p < 0.001] were independent factors associated with non-medical use of prescription drugs. CONCLUSION: Non-medical use of prescription drugs was prevalent among adolescent secondary school students in Buea, Cameroon. Tramadol is the main drug of prescription involved. Our results can guide policymakers on strategies to screen, prevent and control non-medical use of prescription drugs among secondary school students in Cameroon.

Rifampicin resistance among Mycobacterium tuberculosis-infected individuals using GeneXpert MTB/RIF ultra: a hospital-based study.

OBJECTIVES: To determine the prevalence and risk factors associated with rifampicin (RIF)-resistant tuberculosis using GeneXpert technology. METHODS: A cross-sectional study was conducted from April 2018 to November 2019 among tuberculosis (TB)-infected Cameroonian patients in the Littoral Region using records from patients presenting with clinically suspected or documented TB. The patients were screened for TB using GeneXpert MDR/RIF ultra. Data were documented with an ad hoc survey form and analysed with SPSS version 22. RESULTS: 153 patients were included in the study. 64.1% were males; mean age was 37.9 ± 14.7 years and median age 37 years (range: 2-82). Most patients were new cases (76.4%). Relapses accounted for 8.5% and recurrences for 2.6%. Pulmonary TB was diagnosed among 98.7% patients using mostly sputum samples (85%). The prevalence of RIF resistance was 6.7% (95% CI: 3.4%-12.7%). This prevalence was significantly higher in samples of mucus and mucopurulent aspect (P-value = 0.04). RIF-resistant M. tuberculosis strains were significantly more frequent among relapses than new cases (23.1% vs. 2.3% P-value < 0.0001). A statistically significant association was found between GeneXpert-based quantification results and type and aspect of samples. CONCLUSION: This study confirms the circulation of RIF-resistant M. tuberculosis strains in the Littoral region. There is a need for extensive studies in other parts of the country.

Acquisition of Surgical Skills by Final-Year Medical Students in State-Owned Medical Schools of Cameroon: Are We Doing Any Good?

INTRODUCTION: World Health Organization recommends that basic surgical care be administered at the district level. In the absence of qualified surgeons, general practitioners are sometimes proposed to bridge the gap. Medical curricula in low- and middle-income countries must be designed accordingly. The aim of this study was to assess the achievements of training of undergraduate medical students in Cameroon towards meeting this objective. METHODS: A descriptive cross-sectional study was carried out in the four state-owned medical schools in Cameroon. All students who had completed all clinical rotations were assessed with a self-administered questionnaire for their exposure and self-perceived comfort in conducting some selected basic surgical skills and procedures. RESULTS: A total of 304 (87.6%) students returned filled questionnaires. Their self-perceived comfort in surgical skills ranged from 25% (manual node tying) to 86% (surgical scrubbing). Adequate exposure to selected surgical procedures was 87% for repair of perineal tear complicating vaginal delivery, above 80% for caesarean section and incision and drainage of abscess, 73% for cast immobilization of extremity fracture and just above 50% for hernia repair and appendectomy. It was as low as 3% for bowel resection and anastomosis. The choice to perform extra-curricular activity for skills improvement was significantly associated with adequate exposure (p < 0.05). CONCLUSION: Overall, the mastery of practical surgical skills and basic surgical interventions by final-year medical students in Cameroon is insufficient. There is need to reinforce the training and assessment by creating the conditions for an appropriate exposure of medical students during surgical rotations.

Intestinal parasitic infections in relation to CD4(+) T cell counts and diarrhea in HIV/AIDS patients with or without antiretroviral therapy in Cameroon.

BACKGROUND: Intestinal parasitic infections (IPI) are a major public health concern in HIV/AIDS patients particularly in resource-limited settings of Sub-Saharan Africa. Studies investigating the relationship between intestinal parasitic infections and CD4(+) T cell counts and diarrhea in HIV/AIDS patients with or without antiretroviral therapy in the region are not readily available hence the need to perform this study. METHODS: In a comparative cross-sectional study involving 52 pre-ART and 248 on-ART HIV patients. Stool samples were collected and analysed for intestinal parasites by wet and iodine mounts, Kato-Katz, formol ether, modified field staining, and modified Ziehl-Neelsen staining techniques. Blood samples were collected and analysed for CD4(+) T cell counts by flow cytometry. A pre-tested semi-structured questionnaire was used to collect data on socio-demographic and clinical presentation. Data were analysed using STATA version 12.1. Statistical tests performed included the Pearson Chi-square, logistic regression and student's t-test. P < 0.05 was considered to be statistically significant. RESULTS: The prevalence of intestinal parasitic infections in pre-ART and on-ART was 84.6% and 82.3% respectively with no significant difference observed with respect to age (p = 0.06), and gender (p = 0.736). All the opportunistic parasites including Cryptosporidium parvum, Cyclospora cayetanensis, Isospora belli and Microsporidium spp. were isolated from both groups, with only Microsporidium spp. significantly associated with CD4(+) T cell counts below 200 cells/µl in pre-ART (p = 0.006) while Cryptosporidium parvum, Microsporidium spp. and Isospora belli were associated with counts below 200 cells/µl in on-ART. Cryptosporidium parvum was significantly associated with diarrhea in pre-ART (p = 0.025) meanwhile it was significantly associated with diarrhea in on-ART (p = 0.057). The risk of diarrhea was highest in patients with CD4(+) T cell counts below 200 cells/µl (COR = 10.21, p = 0.000) for both pre- and on-ART treatment. CONCLUSION: A very high prevalence of intestinal parasitic infections was observed, which did not differ with respect to ART status. All known opportunistic parasites were isolated in both pre-ART and on-ART patients. Low CD4(+) T cell count may appear to be a factor for intestinal parasitic infections and development of diarrhea. Regular screening and treatment of intestinal parasitic infections is very vital in improving the overall quality of care of HIV/AIDS patients.

Highly active antiretroviral therapy and dyslipidemia in people living with HIV/AIDS in Fako Division, South West Region of Cameroon.

BACKGROUND: The advent of HAART has been associated with a profound reduction in morbidity and mortality from HIV/AIDS. However, side effects and toxicities associated with HAART may lead to an increased risk for cardiovascular diseases. The aim of this study was to determine the prevalence of dyslipidemia and determining factors of derangements in lipid profile associated with the use of HAART regimens in people living with HIV/AIDS in Fako Division of the South West Region of Cameroon. METHODS: This cross-sectional study was conducted between March and August 2014. Lipid profile was determined after overnight fast and dyslipidemia diagnosed according to the US National Cholesterol Education Program III criteria. Socio-demographic characteristics were also collected using a questionnaire. Data was analyzed using STATA; chi-square test, student's t-test, ANOVA and logistic regressions were computed. RESULTS: Two hundred and nine participants were recruited including 157 (75.1 %) on HAART and 52 (24.9 %) HAART-naïve. Antiretrovirals were drugs containing two nucleoside backbones (zidovudine/ /lamivudine/tenofovir) with either a non-nucleoside (nevirapine/efavirenz) or a protease inhibitor (lopinavir). No patient was treated with statins. Their mean age was 43.4 (±11.0) years. The mean CD4(+) T cell count was 425 (±281) cells/µl after mean duration of HIV infection of 54.8 (±43.9) months and mean duration on ART of 63.7 (±41.4) months. The prevalence of total cholesterol (≥ 200 mg/dL) was 51.0 % in patients on HAART and 9.6 % pre-HAART patients (p < 0.0001), whereas LDL-cholesterol ≥ 130 mg/dL occurred in 36.9 % and in 7.7 % respectively, (p = 0.0001). Receiving HAART (adjusted odds ratio =6.24, 95 % CI: 2.33-17.45, p < 0.0001) and HIV duration of 42 months and more (aOR = 2.26, 95 % CI: 1.16-4.42, p = 0.017) were independently associated with total cholesterol ≥ 200 mg/dL. Receiving HAART (aOR = 5.28, 95 % CI: 1.17-16.32, p = 0.004) was independently associated with raised LDL-cholesterol values. The adjusted odds ratio (95 % CI) of BMI ≥ 25.0 kg/m(2) versus BMI < 25.0 kg/m(2) was 3.25 (1.44-7.34) for triglycerides ≥ 150 mg/dL. CONCLUSION: HAART regimens were significantly associated with atherogenic lipid profile. Lipid profile should be monitored in HIV/AIDS patients on therapy so that any negative effects of HAART are optimally managed.

Assessing the risk factors of cholera epidemic in the Buea Health District of Cameroon.

BACKGROUND: Cholera is an acute diarrheal disease caused by the bacterium, Vibrio cholerae. A cholera epidemic occurred in Cameroon in 2010. After a cholera-free period at the end of 2010, new cases started appearing in early 2011. The disease affected 23,152 people and killed 843, with the South West Region registering 336 cases and 13 deaths. Hence, we assessed the risk factors of cholera epidemic in the Buea Health District to provide evidence-based cholera guidelines. METHODS: We conducted an unmatched case-control study. Cases were identified from health facility records and controls were neighbours of the cases in the same community. We interviewed 135 participants on socio-economic, household hygiene, food and water exposures practices using a semi-structured questionnaire. Data was analyzed using STATA. Fisher exact test and logistic regression were computed. P < 0.05 was considered to be statistically significant. RESULTS: The 135 participants included 34 (25.2 %) cholera cases and 101 (74.8 %) controls. More females [78 (57.8 %)] participated in the study. Ages ranged from 1 year 3 months to 72 years; with a mean of 29.86 (±14.51) years. The cholera attack rate was 0.03 % with no fatality. Most participants [129 (99.2 %)] had heard of cholera. Poor hygienic practices [77 (59.2 %)] and contaminated water sources [54 (41.5 %)] were the main reported transmission routes of cholera. Good hygienic practices [108 (83.1 %)] were the main preventive methods of cholera in both cases [23 (76.6 %)] and controls [85 (85.0 %)]. Logistic regression analysis showed age below 21 years (OR = 1.72, 95 % CI: 0.73-4.06, p = 0.251), eating outside the home (OR = 1.06, CI: 0.46-2.43, p = 1.00) and poor food preservation method (OR = 9.20, CI: 3.67-23.08, p < 0.0001) were independent risk factors of cholera. Also, irregular water supply (OR = 0.66, 95 % CI: 0.30-1.43, p = 0.320), poor kitchen facility (OR = 0.60, CI: 0.16-2.23, p = 0.560), lack of home toilet (OR = 0.69, CI: 0.25-1.86, p = 0.490), and education below tertiary (OR = 0.87, 95 % CI: 0.36-2.11, p = 0.818) were independent protective factors for the occurrence of cholera. CONCLUSION: There was a good knowledge of cholera among participants. Poor food preservation method was a significant independent risk factor of cholera. Improvement in hygiene and sanitation conditions and water infrastructural development is crucial to combating the epidemic.

HAART, DOTS and renal disease of patients co-infected with HIV/AIDS and TB in the South West Region of Cameroon.

BACKGROUND: Tuberculosis is the commonest infection among HIV/AIDS patients. This co-infection constitutes a major death threat in the world. There is paucity of data about renal disease amongst patients on HAART and DOTS therapy in Cameroon. METHODS: This was a hospital-based cross-sectional study in the Buea, Limbe and Kumba government Hospitals. Spectrophotometric method was used for the quantitative determination of serum creatinine, urea, albumin and total protein levels. Glomerular filtration rate was estimated using the MDRD method. The student's t test, ANOVA and logistic regression were used to analyse the data. RESULTS: Out of 200 participants, 101 (50.5 %) were males. The ages ranged from 21 to 65 years with a mean age of 38.04 ± 10.52 years. Compared to adults on DOTS alone, adults on HAART alone had a significantly higher prevalence of eGFR <60 ml/min/1.73 m(2) (10/70 (14.3 %) vs. 1/70 (1.4 %), OR = 11.5 [1.4-92.5], p = 0.02) while more participants on HAART/DOTS had significantly higher serum creatinine (18/60 (30 %) vs 10/70 (14.3) OR = 2.57 [1.08-6.12], p = 0.033). Though participants on HAART/DOTS combined therapy had low eGFR, the association was not statistically significant (OR = 6.27, 95 % CI;0.71-55.27, p = 0.098). Participants on the Zidovudine, Lamivudine, Nevirapine regimen showed a statistically significant difference in the mean serum creatinine and albumin levels between the HAART/DOTS combined therapy and HAART group (p = 0.0219 and 0.0001 respectively). CONCLUSION: Compared to adults on DOTS, adults on HAART were more likely to have renal dysfunction (eGFR <60 ml/min per 1.73 m(2)). Adult on a combination of HAART and DOTS had a similar prevalence of renal dysfunction as those on HAART alone. This study showed that the use of the HAART regimen (Tenofovir, Lamivudine and Efavirenz combination) among the HAART treated adults was nephrotoxic. However, other combined HAART and DOTS regimens had no nephrotoxic effect. Abnormal kidney function can be associated with HAART use.

Universal test and treat in Cameroon: a comparative retrospective analysis of mortality and loss to follow-up before and after a strategic change in approach to HIV care.

Introduction: an increasing number of persons living with HIV (PLHIV) are accessing antiretroviral therapy (ART) since the adoption of the universal test and treat (UTT) policy by Cameroon in 2016. We sought to evaluate the effectiveness of the UTT approach to keep this growing number of PLHIV on a lifelong treatment. Methods: a retrospective cohort analysis was conducted at the Nkongsamba Regional Hospital between 2002 and 2020, using routine data to compare the cumulative incidence of loss to follow-up (LTFU) and mortality between PLHIV initiated on ART under UTT guidelines and those initiated under the standard deferred approach. Chi-squared test was used to compare the risk of attrition between the guideline periods while multiple logistic regression modelling was used to adjust for confounders. Results: of 1627 PLHIV included for analysis, 756 (46.47%) were enrolled during the era of UTT with 545 (33.54%) initiated on ART on the same day of HIV diagnosis. The transition to the UTT era was associated with an overall reduction in the risk of LTFU by 73% (aOR = 0.27, 95%CI: 0.17 - 0.45). There was modest evidence that the odds of mortality had increased under the UTT policy by about 3-fold (aOR = 2.86, 95%CI: 0.91-8.94). Same-day initiation had no overall effect on LTFU or mortality. LTFU was lower among the same-day initiators in the first 24 months but increased thereafter above the rate among late initiators. Conclusion: overall ART programme implementation under the UTT has led to a significant decline in LTFU though mortality appeared to have increased. Ongoing efforts to keep patients on long-term treatment should be sustained while other innovative schemes are sought.

Caregiver´s perception of the home-based management of childhood malaria in Baneghang and Fombap health areas in the West Region of Cameroon.

Introduction: adequate community perception of malaria is crucial to improving prevention, diagnosis, and treatment. This study aimed to determine the caregiver´s perception of the home-based management of childhood malaria in Baneghang and Fombap health areas, Cameroon. Methods: a cross-sectional study was carried out to assess the knowledge, attitudes, and practices of home caregivers (HCGs) in Baneghang, a health area under Community Directed Intervention (CDI), and Fombap, a CDI-free health area. Community health workers (CHWs) conducted a census to identify households with under-five children that constituted a sample frame, and then a systematic random sampling was used to select HCGs. Analysis of variance was used to compare the mean score perceptions of HCGs in the management of childhood malaria at the two sites. Results: out of 420 HCGs interviewed, 161 (38.3%), 226 (53.8%), and 271 (64.5%) displayed correct knowledge, positive attitude, and good practice, respectively, towards childhood malaria prevention, diagnosis, and treatment in both study sites. The mean score knowledge of HCGs in Baneghang was significantly higher than that of those in Fombap (7.33 versus 6.94, p < 0.001). The mean score of attitudes of HCGs towards childhood malaria was also higher in Baneghang than in Fombap (6.59 versus 6.29, p=0.013). However, the mean scores of good practices of HCGs on childhood malaria in both health areas were similar (5.94 versus 5.92, p=0.921). Conclusion: home-based management of childhood malaria seems to have contributed to good knowledge and positive attitudes of HCGs on malaria prevention, diagnosis, and treatment.

Prevalence and risk factors associated with precancerous cervical lesions among women in two cities in Cameroon.

Introduction: cervical cancer is the fourth commonest cancer of women world-wide with increasing incidence in developing countries. This study determined the prevalence and assessed risk factors associated with precancerous cervical lesions among women in Cameroon. Methods: this cross-sectional study enrolled 925 women participants of a screening campaign for precancerous cervical lesions from June to November 2018 in the selected hospitals. A convenience sampling technique was used and socio-demographic, sexual and reproductive data collected from consented participants by means of self-administered questionnaire. During the gynaecologic examination, a cervical smear was collected, stained by the Papanicolaou staining technique and the results classified according to the Bethesda 2014 guidelines. Frequency, percentage, Chi square and regression analysis were conducted using SPSS version 20 and p-value considered at 0.05. Results: of the 925 participants aged 25-65 years (mean 40.2±10.2 SD), 113 (12.2%) had the lesions among whom 9 (7.9%) had atypical squamous cells of undetermined significance, 75 (66.4 %) had Low-grade squamous intraepithelial lesion and 29 (25.7%) had high-grade squamous intraepithelial lesion. Factors associated with the lesions were: age 1.85 [1.42-2.41; p= 0.001] and parity [OR= 1.46; 95% CI: 1.30-1.89; P= 0.004]. Conclusion: the prevalence of precancerous lesions was 12.2%. Age, parity were significant risk factors. Regular screening targeting the population at risk in this study becomes a priority.

Treatment Adherence among HIV and TB Patients Using Single and Double Way Mobile Phone Text Messages: A Randomized Controlled Trial.

Background: Research has shown that patients fail to adhere to ART and TB treatment due to the long duration of both therapies, side effects, and forgetfulness. Objective: To assess the role of the double-way and single-way SMS on adherence to HIV and TB treatment. Materials and Methods: A randomized controlled trial among adult HIV and TB patients on treatment at the Buea Regional and Kumba District Hospitals, South West Region, Cameroon, was conducted. Participants were randomly allocated to the control, single-way, and double-way SMS intervention groups. HIV and TB participants were followed independently for a period of 6 months and 3 months, respectively. Baseline and post-intervention data were collected and analyzed using the chi-square and Student's t-tests with statistical significance set at p < 0.05. Results: A total of 210 HIV participants and 84 TB were recruited into the study with a mean age of 41.25 ± 10 years and 37.89 ± 13.27 years, respectively. Optimal adherence to ART and TB treatment at baseline was [65 (31%) CI: 0.247-0.372] and [35 (41.7%) CI: 0.311-0.522], respectively, and after the intervention, it increased to [72 (42.6%) CI: 0.347-0.495] and 41 (61.2%), respectively. There was an increase in adherence to ART among participants in the double-way SMS intervention group from 23 (32.9%) (RR: 1.04, CI: 0.8-1.31, p=0.716) to 29 (48.3%) (RR: 1.06, CI: 0.75-1.50, p=0.746). Combined single-way and double-way SMS significantly increased adherence to ART. Conclusions: The level of adherence was low among HIV and TB participants. The single-way and double-way SMS did not significantly increase adherence. However, a combination of both the double-way and single-way SMS intervention significantly improved adherence to ART.

Home-Based Intervention for the Prevention and Treatment of Malaria Among Children Younger Than 5 Years in the West Region of Cameroon: Protocol for a Randomized Controlled Trial.

BACKGROUND: Although malaria is preventable and curable, 1 child dies of this disease every 2 minutes in Africa. Home-based management of malaria reduces the progression of severe malaria by more than 50%. Scalable, efficacious, and cost-effective strategies are needed to empower the capacities of home caregivers of children younger than 5 years of age in health education, diagnosis, and treatment of malaria at home. OBJECTIVE: The main objective of this trial is to assess the impact of the management provided by home caregivers on the prevention, diagnosis, and treatment of malaria in children younger than 5 years as compared to the home-based malaria management component of the integrated community-directed intervention (CDI) strategy of community health workers (CHWs). METHODS: A randomized controlled trial will be conducted. CHWs have conducted a census of all households where there is at least one child younger than 5 years with their home caregivers. These children and their home caregivers have been randomly placed into the intervention or control groups among the households identified. The trial will allow malaria home-based prevention, diagnosis, and treatment of 350 children younger than 5 years old by home caregivers in the Fombap area (intervention group) where the integrated CDI strategy will not implemented. This group will be compared to the home-based malaria management component of the integrated CDI strategy in which 350 children in the same age group will be followed up by CHWs in the Baneghang area (control group). The primary outcomes will be the prevention, diagnosis, and treatment of malaria in children younger than 5 years of age by home caregivers at home. The secondary outcomes comprise the malaria follow-up indicators produced by home caregivers in the intervention group and those produced by CHWs in the control group. Both descriptive and one-way analysis of variance estimation techniques will be used to compare the mean difference in the 2 strategies. RESULTS: From September 2019 to October 2019, all home caregivers with children younger than 5 years of age were identified in the intervention and control group by CHWs. Following this, 203 home caregivers with their 350 children younger than 5 years were randomly selected and enrolled in the intervention group, while 225 home caregivers with their 350 children younger than 5 years were enrolled in the control group. In the intervention group, 203 home caregivers were trained in November 2019. This home treatment effectively started in December 2019 and will continue until May 2020. CONCLUSIONS: Findings from this randomized controlled trial will contribute to resolving the challenges of severe malaria and to limiting the death due to malaria of children younger than 5 years. This will bring benefits to home caregivers who will know how to promptly diagnose and properly treat malaria in their children at home.

Predictors of contraceptive method mix in the Cameroon development corporation plantation camps.

INTRODUCTION: low socioeconomic status is a risk factor for maternal death and contraceptive use has been shown to reduce maternal deaths in those poor settings. Despite the tremendous benefits of contraceptives in the regulation of reproductive health indicators, its use in less developed countries continue to remain unacceptably low. The purpose of this study was primarily to assess the contraceptive method mix and then determine the predictors of contraceptive use in the Cameroon Development Corporation (CDC) plantation camps. METHODS: mix sampling was used. Firstly, two CDC camp localities (Tiko and Pena Mboko) were purposively selected. Pre-existing clusters within these localities were then randomly selected and then eligible participants within the sampled clusters systematically selected. Using the main street junction as starting point, direction of sample collection was determined by spinning a plastic bottle. From the start of street junction and moving in direction of the bottle pointer, all households left to the principal investigator were visited in search of eligible participants which were sexually active women aged 15-49 years who gave consent/assent. One participant was selected per household. We used pretested interviewer-administered questionnaires that covered information on socio-demographic characteristics, reproductive health and contraceptive use. Statistical significance was set at p-value ≤ 0.05. RESULTS: six hundred and thirty four (634) sexually active women aged 15-49 years were included in the study; majority were 25-35 years (246; 38.8%). The current contraceptive prevalence was 63.1% [59.3-66.8] (400); of which 312 participants (78%) used a single method while 88 (22%) participants used contraceptives in combination. The most common methods in use were rhythm (196; 49%), male condom (109; 27.2%) and implants (63; 15.8%). When adjusted, statistically significant determinants for contraceptive use were age range and marital status such that odds of using contraceptives was lower in women < 35 years and those cohabiting (AOR= 0.71 [0.50-1.00] and AOR=0.62 [0.44-0.87] respectively). CONCLUSION: current contraceptive practice in the CDC plantation camps is geared toward less effective traditional methods than the more effective modern methods. More health education is needed to adjust this paradigm.

Undernutrition among under-five indigenous Mbororo children in the Foumban and Galim health districts of Cameroon: a cross-sectional study.

INTRODUCTION: despite increasing research interest on Indigenous peoples´ health worldwide, the nutritional status of Indigenous children in Cameroon remains unknown. This study was conducted to assess the prevalence of stunting, wasting, and underweight among under-five Indigenous Mbororo children in the Foumban and Galim health districts of the West Region. METHODS: a cross-sectional study was conducted involving 472 child-caregiver pairs from 16 Mbororo Communities in the Foumban and Galim health districts. Interviewer-administered questionnaires were used for data collection. Anthropometric measurements were collected using standard procedures. Socio-demographic data were analyzed using descriptive statistics. Anthropometric indices: height-for-age, weight-for-height, and weight-for-age - z-scores were analyzed using z-score 06 Stata version 11 and compared with World Health Organization growth reference standards. Ethical approval was obtained from the Faculty of Health Sciences Institutional Review Board of the University of Buea. RESULTS: overall prevalence of stunting, wasting and underweight were 55.08% (95% CI: 50.5-59.58), 13.77% (95% CI: 10.65-16.89), and 31.99% (95% CI: 27.76-36.21), respectively. Severe stunting, wasting and underweight were 34.53% (95% CI: 30.22-38.83), 3.18% (95% CI: 1.58-4.76), and 10.59% (95% CI: 7.80-13.37), respectively. Rates of stunting, wasting and underweight for female and male were: 56.88% and 52.71%; 12.38% and 14.72%; and 30.73% and 32.55%, respectively. Stunting, wasting and underweight rates varied with child age. CONCLUSION: the prevalence of undernutrition was high, indicating a serious public health problem and the necessity for strategies to ensure the optimal health of the target population.

Impact of Nutrition Education on the Nutrition Capacity of Caregivers and Nutrition Outcomes of Indigenous Mbororo Children in the West Region of Cameroon: Protocol for a Cluster Randomized Controlled Trial.

BACKGROUND: Inadequate diets and life-threatening infections have profound adverse implications for child growth, development, and survival, particularly among indigenous peoples. Evidence of the effectiveness of community-based nutrition education interventions in improving child feeding and nutrition outcomes among indigenous Mbororo population in Cameroon is scarce. OBJECTIVE: This study aims to investigate the impact of culturally tailored community-based nutrition education intervention on caregivers' knowledge, attitude, and practice regarding complementary feeding and on nutrition outcomes of indigenous Mbororo children (aged 3-59 months) in the Foumban and Galim health districts of the West Region of Cameroon. METHODS: A two-arm cluster randomized controlled trial will be conducted in the Foumban Health District and Galim Health District. The intervention and control arms will each comprise 5 clusters with 121 child-caregiver pairs. Participants in the intervention arm will be organized into 5 caregivers' peer-support platforms. A total of 12 educational sessions will be assigned to the intervention group by trained female Mbororo nutrition volunteers (n=6) and community health workers (n=6). The control arm will receive routine facility-based nutrition education. Data will be collected at 3-month and 6-month follow-up. Both descriptive statistics and multivariate logistic models will be used to estimate the effect of culturally tailored community-based nutrition education intervention (independent variable) on outcome variables (caregivers' knowledge, attitude, and practice), child growth (weight, height/length, weight for age), and morbidity status (diarrhea, cough, and fever) between both arms. Data assessors will be blinded to the group allocation. Ethical approval (reference no. 2019/1002-07/UB/SG/IRB/FHS) was obtained from the Faculty of Health Sciences Institutional Review Board at the University of Buea. RESULTS: Baseline data were collected in September 2019. In February 2020, 10 Mbororo communities (clusters) with 242 child-caregiver pairs were selected and allocated to the experimental and control arm in a 1:1 ratio. Community nutrition volunteers (n=6) and community health workers (n=6) were selected and trained. Data collection and analysis are ongoing, and results are not available for this manuscript. CONCLUSIONS: The findings of this study will provide evidence on the impact of culturally tailored and health belief model-based nutrition education on behavior change as a complementary strategy for strengthening health facility-based approaches in the reduction of malnutrition burden among the study population.

Prevalence of unrecognized or "silent" myocardial ischemia in chronic kidney disease patients: Protocol for a systematic review and meta-analysis.

INTRODUCTION: Chronic kidney disease (CKD) patients are at an extremely high risk of silent myocardial ischemia (SMI). However, there is a dearth of evidence on the worldwide prevalence of this very lethal and yet unrecognizable complication of CKD. The proposed systematic review and meta-analysis aims to estimate the global prevalence of SMI among CKD patients. METHODS AND ANALYSES: This protocol was conceived according to the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) statement. The systematic review will involve all observational studies and clinical trials published until April 30, 2021, and reporting on the prevalence of SMI in CKD patients. Electronic sources including MEDLINE, Embase, Web of Science, and Cochrane database of systematic reviews will be perused for potentially eligible studies, restricted to only studies published in English or French. Two investigators will independently select studies and use a pre-pilot tested form to extract data. Further, they will independently perform a qualitative assessment of the risk of bias and overall quality of the selected studies, followed by a quantitative assessment using funnel plots and Egger's tests. The heterogeneity between studies will be assessed with the Cochrane's Q statistic, and the I2 statistic will measure the percentage of variation across studies that is due to their heterogeneity rather than chance; the I2 will decide if a meta-analysis can be conducted. In case it cannot be conducted, a descriptive analysis will be performed. Otherwise, study-specific estimates will be pooled using either a fixed-effects or a random-effects model, depending on the value of the I2 statistic. Subgroup and random effects meta-regression analyses will further investigate the potential sources of heterogeneity. Finally, sensitivity analyses will be performed to measure the impact of low-quality studies on the results of the meta-analysis, and power calculations will determine the probability that we will detect a true effect if it does exist. PROSPERO REGISTRATION NUMBER: CRD42020211929. STRENGTHS AND LIMITATIONS OF THIS STUDY: The intended systematic review and meta-analysis will fill the knowledge gap on the global prevalence of silent myocardial ischemia (SMI) in CKD patients. The eligible studies will be identified through a methodic literature search followed by a rigorous screening process; we will then use robust meta-analysis tools to pool the data and provide reliable estimates of the global prevalence of SMI in CKD patients. Two major limitations could be: the predominance of clinical trials that might limit the generalizability of the findings, given that some informative patients might have been sidelined by the strict inclusion criteria of these studies; the high probability of type 1 error originating from the important number of subgroup and sensitivity analyses.

Clinical and epidemiological characteristics and outcomes of patients hospitalized for COVID-19 in Douala, Cameroon.

INTRODUCTION: the coronavirus disease (COVID-19) is a disease that originated from Wuhan in December 2019. It rapidly spread across the globe causing high mortality especially among the elderly. Africa though not spared has limited studies regarding its effects on its population. We therefore sought to describe the epidemiological and clinical characteristics of COVID-19 in Douala, Cameroon. METHODS: we conducted a single-centre, retrospective, and observational study by reviewing records of patients managed for COVID-19 between the 8th March 2020 and 31st, May 2020. Cases were confirmed by real-time reverse transcriptase - polymerase chain reaction and were analysed for epidemiological, demographic, clinical, and radiological features. Outcomes were either clinical improvement by Day-28 or in-hospital mortality. RESULTS: we analyzed 282 case files, 192 were males (M: F=2: 1). The mean age was 52 (+/- 15) years. Hypertension and diabetes accounted for 75% of the chronic medical conditions identified. Main presenting complaints were dyspnea, cough, asthenia, and fever (55-60%). Radiographic analysis showed a ground-glass appearance in 85% of cases. Chloroquine/Hydroxychloroquine was the most (91.8%) frequently used drug in management protocols, 35% needed oxygen supplementation while 6 patients were intubated. Severe pneumonia (11.3%) was the commonest complication. They were 91 admissions in the intensive care unit. The average length of hospital stay was 10 (+/- 5) days. The mortality rate was 32%. CONCLUSION: our findings are concordant with universally reported data of COVID-19 hospitalised patients. These parameters are essential in designing effective prevention and control programs aimed at reducing the impact of the COVID-19 pandemic particularly in countries with limited resources.

One-Way and Two-Way Mobile Phone Text Messages for Treatment Adherence Among Patients With HIV: Protocol for a Randomized Controlled Trial.

BACKGROUND: Incomplete adherence to antiretroviral therapy (ART) is one of the factors that contribute to HIV drug resistance, and it is a major problem for the public health system in controlling the HIV pandemic. There is emerging evidence that SMS can play an important role in health care delivery among patients with HIV on ART, especially in resource-limited settings. OBJECTIVE: This paper aims to assess the impact of two-way and one-way SMS text messaging on adherence to HIV treatment. We hypothesized that sending weekly text messages through the one-way and two-way SMS text messaging approach will improve adherence to ART among patients with HIV and improve associated clinical outcomes (quality of life). METHODS: A randomized controlled trial is being carried out among participants with HIV who have been on ART for at least one month from an accredited treatment center, namely the Buea Regional Hospital and Kumba District Hospital of South West Region, Cameroon. Participants with HIV, both male and female, aged 21 years and older make up a sample size of 207. The interventions involved the use of mobile phone text messages. Before commencing the intervention, a focus group discussion was carried out among the participants to understand their perception about the use of SMS-based interventions to improve adherence. A total of 246 participants were randomized to receive either a one-way text message (SMS sent to a recipient without recipient sending a reply) or two-way text message (SMS sent to a recipient and recipient sends a reply) or the control (no SMS, only standard care). Data on adherence and quality of life were collected at baseline and after 6 months and will be analyzed using SPSS version 21, while qualitative data will be analyzed using Atlas.ti 7.5. RESULTS: Data collection began in September 2019 with focus group discussions and baseline data collection. After 1 month of baseline data collection, the intervention began in October 2019, and postintervention data were collected after 6 months (March 2020). At the end of the study, we will be able to understand the perception of patients toward SMS text messaging-based interventions and also assess the impact of one-way and two-way SMS text messages on treatment adherence among patients with HIV and on associated clinical outcomes (quality of life). CONCLUSIONS: The impact of SMS text messaging varies across different settings. The results from this study will determine the perception of patients toward an SMS text messaging-based intervention and its impact on adherence to ART.

Stigmatization among People Living with HIV/AIDS at the Kumba Health District, Cameroon.

We determined the level, type of stigma, and risk factors associated with stigmatization of people living with HIV/AIDS (PLWHA) by conducting a cross-sectional study from April to June 2018 in 3 HIV treatment centers in the Kumba Health District (KHD), Cameroon. We reviewed hospital registers, conducted focus group discussions, and administered structured questionnaires. For data analysis, we used the Statistical Package for Social Sciences version 20.0. We recorded a total stigma index score of 59.1. Internal stigma (odds ratio [OR] 2.91; 95% confidence interval [CI]: 1.74-4.98) was common in PLWHA. Also, younger age <30 years (adjusted OR [AOR]: 0.39; 95% CI: 0.17-0.94) was linked with stigma reduction while low level of education (AOR: 1.74; 95% CI: 1.02-2.97) increased the stigma level. HIV-related stigma is pervasive in the lives of PLWHA, with most of them having internal stigmatization. Appropriate health education on HIV will be crucial in reducing stigmatization in the KHD.
