Systematic review of therapeutic outcomes of multidrug resistant tuberculosis and their predictors in adults receiving integrated treatment of tuberculosis and human immuno-deficiency virus in low- and middle-income countries: a study protocol
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

Immune response to hepatitis B vaccine following complete immunization of children attending two regional hospitals in the Southwest region of Cameroon: a cross sectional study.
BACKGROUND: Hepatitis B virus (HBV) infection despite being a vaccine preventable disease remains a global public health problem. In Cameroon, the hepatitis B vaccine was introduced in the expanded program on immunisation in 2005, but there has been limited evaluation of the HBV surface antibody response post vaccination. OBJECTIVE: We investigated the immune response to hepatitis B vaccine in infants who received the DPT-Hep B-Hib vaccine, and we assessed HBsAg carriage in non-responders. We also investigated factors associated with non-response or poor response. METHODS: Using a hospital based cross sectional design and a structured questionnaire over a four-month period (January to April 2019), we collected data to determine factors associated with hepatitis B surface antibody (anti-HBs) response from infants aged 6 to 9 months attending infant welfare clinics (IWC) at the Buea and Limbe regional hospitals. We collected venous blood and measured anti-HBs titres using a quantitative Foresight® ELISA. We entered and analysed data using EpiData version 3.1 and SPSS version 25 respectively. RESULTS: Of the 161 infants enrolled, 159 (98.8%) developed anti-HBs antibodies. Of these 159, 157 (97.5%) and 117 (72.7%) developed ≥ 10.0 mIU/ml (seroprotection) and ≥ 100.0 mIU/ml anti-HBs titres respectively. Being younger (6 months old) was associated with seroprotection (Cramer V = 0.322, p = 0.001). Spearman rho's relational analysis showed that immunity against HBV reduced as the duration since the last dose increased (r = -0.172; P = 0.029). However, a Firth logistic regression showed no significant association of factors with inadequate immunity. All 12 (7.5%) infants exposed to HBV at birth, received the hepatitis B vaccine at birth, including four who received HBIG, and all were protected. Four infants (2.5%) had anti-HBs titres < 10.0 mIU/mL (non-responders) but had no peculiarity. CONCLUSION: The seroprotective rate following hepatitis B vaccination of infants is high even in exposed infants. Our study suggests that Cameroon's HBV vaccine in the Expanded Program on Immunisation (EPI) is effective against HBV, although we could not account for the 2.5% non-response rate. Large scale studies are needed to further explore non-response to the vaccine
Prevalence and predictors of recreational drug use among medical and nursing students in Cameroon: a cross sectional analysis
Abstract Objective Medical and nursing students in Cameroon are likely to have mental health problems given the stressful nature of their studies. Paucity of mental health institutions in the country implies they hardly get access to professional help when needed and are obliged to develop coping strategies such as recreational drug use. This study aims to determine the prevalence and predictors of recreational drug use among a group of Cameroonian medical and nursing students. Results Cross-sectional analysis of 852 medical and nursing students (mean age 21.78 ± 3.14, 31.49% males) recruited by convenience sampling from three state-owned medical schools; and from two state-owned and two private nursing schools in Cameroon over a four-month period (January–April 2018). Information was collected via a printed self-administered and structured questionnaire from consenting students. Multivariable logistic regression analysis was used to identify independent predictors of recreational drug use. The overall prevalence of recreational drug use was 1.64% with tramadol and marijuana noted as the drugs used by these students. Independent predictors of recreational drug use were: presence of a chronic illness (OR 5.26; 95% CI 1.32, 20.97; p = 0.019), alcohol consumption (OR 5.08; 95% CI 1.54, 16.73; p = 0.008) and Total Oldenburg Burnout Inventory score (OR 1.11; 95% CI 1.02, 1.21; p = 0.021). The use of recreational drugs by medical and nursing students in Cameroon remains worrisome despite its very low prevalence, as it may negatively impact their performance and health
Iron supplementation in pregnant sicklers: an opinion
Abstract Morbidity associated with iron deficiency anaemia in pregnancy is increased in the presence of sickle cell anaemia. Iron supplementation in pregnant sicklers in a bid to resolve iron deficiency anaemia is recommended only after laboratory confirmation of iron deficiency. However, the greatest burden of sickle cell disease is seen in low and middle income countries where equipment for measuring body iron indices are unavailable. Sickle cell anaemia is an inherited disorder of haemoglobin synthesis characterized by life-long severe haemolytic anaemia. People with sickle cell anaemia are at increased risk of iron overload from haemolysis and recurrent multiple transfusions. Iron overload a complication of sickle cell disease, which is more often in thalassemias, is typically given undue fear in sickle cell anaemia especially in patients with no recent transfusion history. About a third of the haemolysis in sickle cell anaemia is intravascular, and the resulting excess iron is lost in urine. This may lead to a negative iron balance and iron deficiency. There is little evidence of iron overload in pregnant sicklers, and iron deficiency may be more common than suspected. Even when iron overload does occur in a condition called siderosis, the deposited iron is irreversible and thus cannot be reused by the body in case of susceptibility to iron deficiency. More so, in pregnancy there is an increase in the body’s iron requirement by about 1000–1200 mg which is usually not met by dietary intake. Iron supplements could be given to pregnant sicklers, caution should however be taken in patients with history of recurrent transfusion. Anaemia is a common and feared complication in pregnancy. The co-existence of iron deficiency anaemia and sickle cell anaemia worsens prognosis of pregnancy. Iron overload a possible complication of sickle cell anaemia is related to multiple transfusions. The urinary losses from intravascular haemolysis and increased dietary requirement in pregnancy predispose even pregnant sicklers to iron deficiency anaemia. Iron supplements should thus conveniently be given to pregnant sicklers with no history of recurrent transfusions

Noncommunicable diseases behavioural risk factors among secondary school adolescents in Urban Cameroon.
Acknowledgements: Not applicable.Adolescence is a crucial period for noncommunicable disease (NCD) risk factors, and interventions to reduce the NCD burden must target this age group. This study aimed to evaluate the NCD behavioural risk factors in adolescents attending state secondary schools in an urban setting in Cameroon. We conducted a cross-sectional survey using adapted structured questionnaires to assess the prevalence and correlates of NCD behavioural risk factors among adolescents attending selected urban state secondary schools in Douala IV, one of the six subdivisions in Douala, Cameroon. Of the 645 students who completed the study questionnaires, half of them did not have adequate knowledge about NCDs and their risk factors. Only 20% met recommended physical activity levels, nearly half lived sedentary lifestyles, and only 7% ate a healthy diet. Almost half of all participants reported drinking alcohol during the month, while 3% reported cigarette smoking. Participants with inadequate knowledge of NCDs were more likely to have elevated blood pressure values, and males had increased odds of high blood pressure. Contrarily, being male appeared to be protective against overweight and obesity. The odds of being sedentary decreased with age, and the odds of alcohol drinking seemed to grow with a higher maternal level of education. Our survey shows inadequate knowledge about NCDs and a high prevalence of NCD behavioural risk factors in adolescents in urban state secondary schools in Cameroon. These findings predict a higher NCD burden in future adults in the country, reinforcing the need for urgent public health interventions, especially regarding knowledge and sedentary living. Further research is needed to establish the transition of adolescent risk factors to adult disease through life course approaches in these settings
