Malaria prevention in Cameroon mainly relies on the use of ITNs. Although several free distribution campaigns of treated nets have been conducted across the country, bed net usage remains very low. A household survey was conducted to assess knowledge of the population and practices affecting treated net usage in the city of Yaoundé. A community-based descriptive cross-sectional survey was conducted in January 2017 in 32 districts of the city of Yaoundé. Parents (household head, spouse or an elder representative) who consented to the study, were interviewed using a structured pre-tested questionnaire. Interviews were conducted in French or English. A questionnaire consisting of 22 questions was administered to know (i) people’s knowledge and attitude on preventive measures; and, (ii) attitudes concerning the treatment of malaria and estimated amount spent for malaria prevention and treatment. A total of 1643 household heads were interviewed. Over 94% of people interviewed associated malaria transmission to mosquito bites. The main methods used against mosquito bites were: treated bed nets (94%; n = 1526) and insecticide spray or coils (32.2%; n = 523). The majority of people interviewed reported using bed nets mainly to prevent from mosquito bites (84.4%, n = 1257), rather than for malaria prevention (47.3%). Knowledge and attitude analysis revealed that people with university or secondary level of education have better knowledge of malaria, prevention and treatment measures compared to those with the primary level (OR = 7.03; P < 0.001). Also, wealthy households were more aware of good practices concerning malaria prevention and treatment compared to poor ones. In the majority of districts of Yaoundé, over 50% of people interviewed per district, had good knowledge of malaria and prevention measures but less than 50% applied good practices concerning malaria treatment and prevention. The amount spent annually by a household for vector control was CFAF 11,589 ± 1133 (US$21.87 ± 2.14) and CFAF 66,403 ± 4012 (US$125.29 ± 7.57) for malaria treatment. The study indicated that, despite good knowledge of malaria and prevention measures, few people apply good practices. More sensitization needs to be done to improve adherence to good practices concerning malaria prevention and treatment.

Background. Biomedical waste (BMW) is defined as unwanted materials generated during diagnosis, treatment, operation, immunization, or in research activities including production of biologicals. Healthcare workers are responsible for the proper management of this waste for human safety and for the protection of the environment.Methods. An analytical knowledge, attitude, and practice (KAP) study was carried out at Biyem-Assi District Hospital from June 1st to July 5th, 2018, including 100 health workers from different departments. Variables of interest were knowledge, attitudes, and practices of the respondents. A structured and pretested questionnaire was used for data collection. Data analysis was carried out using software Epi Info version 7.2.2.6. Logistic regression was used to establish the relationship between knowledge, attitudes, and practices.Results. Nurses constituted 32.0% of the participants, and more than half of the participants had 1–4 years of working experience (56.0%). Overall, the level of knowledge was satisfactory at 50.0%, that of attitudes was as unfavorable at 83.0%, and that of practices was as poor at 50.0%. Favorable attitudes were associated to satisfactory level of knowledge (ORa = 5.14 [3.10–8.51] andp=0.005). Good practices were associated to good level of knowledge (ORa = 5.26 [3.17–8.7] andp<0.001) and a favorable attitude (ORa = 7.30 [2.25–23, 71] andp<0.001).Conclusion. The level of knowledge was considered unsatisfactory for half of the staff interviewed. Attitudes were unfavourable at 83.0% and poor practices at 50.0%. Staff with a good level of knowledge were more likely to have favourable attitudes towards BWM. Also, good knowledge and attitude positively influenced the practice with regard to BMW management.

The objectives of this study were to identify the associated factors with cancerous and precancerous lesions of cervix. In Africa, the incidence of uterine cervical neoplasms varies from one region to another, where most women with uterine cervical neoplasms are seen at an advanced stage. For this reason, uterine cervical neoplasms mass screening reduces the incidence and mortality due to this disease, similar to what is being done in Europe. A cross-sectional analytical study was conducted. Socio-demographic characteristics, gynaecological-obstetrical history, risk factors, data from visual inspection with acetic acid and visual inspection with Lugol, colposcopy impressions and results of cytological analysis were performed. A simple and multiple regression were performed to establish a statistically significant difference between certain factors and the presence of precancerous or cancerous lesions of uterine cervical. In this study, of 63 women diagnosed histologically, 43 had precancerous lesions and 20 had cancerous lesions. we found that being older than 35, having the first intercourse before 18, having an antecedent of STI, being a widow and using of tobacco were risk factors associated with precancerous lesions (p = 0.013 with OR = 3.44 (1.22–9.73), p = 0.009 with OR = 4.07 (1.69–13.08), p < 0.001 with OR = 3.80 (1.94–7.47), p < 0.001 with OR = 9.77 (3.87–24.70) and p < 0.001 with OR = 5.47 (2.60–11.52)) respectively. Only being older than 45, being a widow and using tobacco were risk factors associated with cancerous lesions (p = 0.021 with OR = 2.01 (1.58–3.56), p = 0.02 with OR = 2.96 (2.10–3.87), p = 0.041 with OR = 1.98 (1.46–2.44)) respectively. Among participants diagnosed with uterine cervical neoplasms, there was a significant association with the STI, marital status and smoking. Despite the integration of the detection of precancerous uterine cervical neoplasms lesions into health facilities in Gabon, uterine cervical neoplasms ranks second among women’s cancers in terms of incidence and first in terms of mortality.

The emergence and spread of multidrug-resistant tuberculosis (MDR-TB) presents a challenge to the "End TB by 2035" strategy. This study aimed to identify the risk factors associated with MDR-TB in patients admitted to the pneumo-physiology clinic of the National University Hospital of Bangui in Central African Republic. This was a "retrospective" chart review study. Cases were represented by patients more than 18 years of age treated for MDR-TB and controls were patients with "at least rifampicin-susceptible" TB treated "with first-line anti-TB regimen" and who at the end of treatment were declared cured. The status of "cured" was exclusively applicable to non-MDR TB. Risk factors associated with MDR-TB were identified by multivariate analysis. We included 70 cases and 140 controls. The median age was 35 years, IQR (22;46 years). The main factors associated with the occurrence of MDR-TB in multivariate analysis were male gender (0 R = 3.02 [1.89-3.99], p = 0.001), residence in a peri-urban/urban area (0 R = 3.06 [2.21-4.01], p = 0.002), history of previous TB treatment (0 R= 3.99 [2.77-4.25], p < 0.001) and the presence of multidrug-resistant TB in the family (0 R=1.86 [1.27-2.45], p = 0.021). The emergence of MDR-TB can be reduced by implementing appropriate strategies, such as preventive therapy in contacts of MDR-TB patients and detecting and appropriately treating MDR-TB patients to prevent further spread of infection.

In Gabon, the proportion of maternal deaths directly related to Primary PostPartum Haemorrhage (PPPH) is 15 to 25%, despite the different means that the World Health Organization has made available to the providers of Emergency Obstetrical and Neonatal Care (EmONC). The objective of this study was to determine the prevalence and epidemiological characteristics of Primary PostPartum Haemorrhage to improve its management and reduce the rate of maternal deaths. An analytical retrospective study involved 42,728 records, whose data were collected using a chart collection form on the basis of information contained in partograms and other patient records. Sociodemographic variables were expressed using percentage. The relationship between the etiologies of PPPH and certain characteristics of the women was established using the ORs with their 95% confidence intervals. The difference was significant if p < 0.05. The prevalence of PPPH was 1.6%. Delivery haemorrhages accounted for 65.5% of PPPH. The main factors associated with delivery haemorrhages were pauci parity and multiparity (p = 0.003 and 0.051), post-term (p = 0.042), and birth weight >4,000 g (p = 0.006). Those associated with genital tract injuries were young maternal age (p = 0.008) and multiparity (p = 0.028). The most common etiology was haemorrhage from delivery. Multiparity remains the most common risk factor and the young age of the patients. It is important to improve management through better assessment of blood loss in the primary postpartum period as well as capacity building of health providers on EmONC.

The objectives of this study were to determine the incidence and risk factors of tuberculosis (TB) among people living with HIV (PLHIV). A cohort study was carried out in an HIV infection management centre in Bangui. PLHIV aged 18 or older, with no history of TB, enrolled between January 1, 2017 and December 31, 2018 were included in the study. The chi-square test was used only to compare the proportions at the 5% significance level. To determine the risk factors, we used the Cox regression adjusted hazard ratio, using Epi Info 7 software. A total of 677 patients including 618 (91.28%) on antiretroviral therapy were included in the study. The median age was 34 with extremes ranging from 18 to 57. Of the patients followed, 104 developed TB. The overall incidence of TB was 15.37 (104/677) cases per 100 PLHIV-years. This incidence was 13.10 (81/618) cases per 100 in patients on ART-years and 38.99 (23/59) cases per 100 patients on pre-ART-years. In pre-ART patients the incidence of TB was therefore almost 3 times higher than that of PLHIV on ART (p = 0.03). WHO clinical stages III and IV (p = 0.02), absence of ART (p = 0.03), poor adherence (p = 0.004) and low functional capacity (p = 0.04) were the risk factors associated with the occurrence of TB among PLHIV in Bangui. The high incidence of TB in our context is essentially linked to delay in diagnosis and the quality of care. Early initiation of antiretroviral therapy, systematic screening for TB in PLHIV upon entry into the active queue and better monitoring of patients on ART are strongly recommended.
