Awareness of breast cancer and breast self-examination among female undergraduate students in a higher teachers training college in Cameroon
Introduction: The incidence of breast cancer (BCa) in Cameroon is on the rise and accounts for a leading cause of mortality. An understanding of the knowledge and practices on breast cancer and breast self-examination (BSE) among teachers are important first steps which will guide the designing of interventions aimed at raising awareness across the general population. Methods: We conducted a cross-sectional study in April 2016 involving 345 consenting female undergraduate students in the Higher Teachers Training College, Bambili, Cameroon. Data was collected using a pretested self-administered questionnaire and analysed using descriptive methods. Results: The mean age of the respondents was 22.5±3.2years and a vast majority (n = 304, 88.1%) had heard about BCa primarily from the television/radio (n=196, 64.5%). Overall, less than a quarter (n=65, 21.4%) of respondents who had heard about BCa had sufficient knowledge on its risk factors and signs/symptoms. A plurality (53.3%) thought BCa can be prevented via vaccination while over a third (38.7%) opined that BCa can be treated spiritually. Less than half (47%) of respondents who had heard about BCa had heard about BSE amongst which only 55 (38.5%) had ever practiced it. Conclusion: Though most students are aware of the existence of breast cancer, their overall knowledge on its risk factors and clinical presentation is insufficient with a concomitant low practice of BSE. These highlighted gaps warrants intensification of sensitization campaigns and educational programmes in order to raise knowledge levels and enhance prevention strategies that would aid in reducing the burden of breast cancer in Cameroon

Air Pollution and Racial Disparities in Pregnancy Outcomes in the United States: A Systematic Review
Background: Exposure to air pollutants and other environmental factors increases the risk of adverse pregnancy outcomes. There is growing evidence that adverse outcomes related to air pollution disproportionately affect racial and ethnic minorities. The objective of this paper is to explore the importance of race as a risk factor for air pollution-related poor pregnancy outcomes. Methods: Studies investigating the effects of exposure to air pollution on pregnancy outcomes by race were reviewed. A manual search was conducted to identify missing studies. Studies that did not compare pregnancy outcomes among two or more racial groups were excluded. Pregnancy outcomes included preterm births, small for gestational age, low birth weight, and stillbirths. Results: A total of 124 articles explored race and air pollution as risk factors for poor pregnancy outcome. Thirteen percent of these (n=16) specifically compared pregnancy outcomes among two or more racial groups. Findings across all reviewed articles showed more adverse pregnancy outcomes (preterm birth, small for gestational age, low birth weight, and stillbirths) related to exposure to air pollution among Blacks and Hispanics than among non-Hispanic Whites. Conclusion: Evidence support our general understanding of the impact of air pollution on birth outcomes and, specifically, of disparities in exposure to air pollution and birth outcomes for infants born to Black and Hispanic mothers. The factors driving these disparities are multifactorial, mostly social, and economic factors. Reducing or eliminating these disparities require interventions at individual, community, state, and national level.</p
Pulmonary hypertension in low- and middle-income countries with focus on sub-Saharan Africa
Pulmonary hypertension (PH) is a devastating, progressive disease with increasingly debilitating symptoms and usually shortened overall life expectancy. This article reviews the global epidemiology of PH with focus on low- and middle-income countries (LMICs) and sub-Sahara African in particular. Although left ventricular heart disease is the most common cause globally, the main contributing risk factors in LMICs are chronic infectious diseases especially human immunodeficiency virus (HIV) and schistosomiasis. Other important risk factors of PH are rheumatic heart disease, untreated congenital heart disease (CHD), and sickle cell disease. Despite existing epidemiological data of PH risk factors suggesting a high prevalence in sub-Saharan Africa (SSA), the available literature is limited. International registries in LMICs like the pan African pulmonary hypertension cohort (PAPUCO) study are essential to provide information about the causes, treatment, outcome, and the natural course of PH in Africa and other parts of the world. In addition, there is a need to track diagnostic and management practices in order to develop suitable algorithms to diagnose PH in LMICs

How to effectively plan a scientific event in resource limited setting
Every day, scientists organize events. Whether you are planning a small event such as a research training workshop or a bigger event such as an international scientific conference, you have to plan well. The success of an event largely depends on how well it is planned. There are several important steps in event planning process that any organization can follow
Prevalence and factors associated with depression among medical students in Cameroon: a cross-sectional study
Abstract Background Depression is an important contributor to the global burden disease that affects people of communities all over the world. With high level of demands in academics and psychosocial pressure, medical students during their course of training tend to become depressed, leading to problems later in professional life and compromising patient care. In Cameroon, there is lack of data on the prevalence of depression and its impact on medical students. To determine the prevalence and predisposing factors associated with depression among medical students in Cameroon (preclinical and clinical). We also evaluated the impact of depression on self-reported academic performance. Methods A cross sectional study was carried out in all 4 state medical schools in 4 different regions from December 2015 to January 2016. Diagnosis of depression, major depression and its associated factors were assessed using the 9-Item-Patient Health Questionnaire (PHQ-9) and a structured questionnaire respectively. We included 618 medical students (response rate: 90.4%). Results About a third of them (30.6%, 95% CI: 22.8–36.7) were found to have major depressive disorder (PHQ Score ≥ 10). With regards to the severity of depression, 214 (34.6%), 163 (26.4%), 21 (3.4%), and 5 (0.80%) students were classified as having mild, moderate, moderately severe and severe depression respectively. The presence of a chronic disease (OR: 3.70, 95% CI: 1.72–7.94, p = 0.001), major life events (OR: 2.17, 95%CI: 1.32–3.58, P = 0.002), female gender (OR: 1.59, 95% CI: 1.06–2.37, p = 0.024) and being a student at the clinical level (OR: 4.26, 95% CI: 2.71–6.71, p < 0.001) were independently associated with depression. There was no association between depression and self-reported academic performance, (OR: 1.2, 95% CI: 0.9–1.7, p = 0.080). Conclusion The prevalence of major depressive disorders among medical students in Cameroon is high and is associated with the presence chronic disease, major life events, female gender and being a student at the clinical level. So we recommend clinicians attending to medical students with demographic features suggestive of greater risk of depression, to make an in depth investigation on the possible presence of depression. Despite this high prevalence of major depression among medical students, it was not associated with self-reported academic performance
A diagnostic algorithm for pulmonary hypertension due to left heart disease in resource-limited settings: can busy clinicians adopt a simple, practical approach?
Pulmonary hypertension (PH) has progressively moved from an orphan disease to a significant global health problem with a major disease burden in limited-resource countries, where over 97% of patients live. The aetiologies of PH differ between high- and low-income nations, but PH due to left heart disease is credited to be the most frequent contemporary form. Although a straightforward diagnosis of PH requires the use of right heart catheterisation (RHC), access to equipment for RHC is a deterrent. Furthermore, the risk associated with RHC limits its uptake to a selection of specialised centres. Moreover, the rigour and clinical reasoning for diagnosis in clinical medicine is rapidly changing and revealing that PH can complicate a diverse range of medical conditions needing other explorations. In this article, we provide for the busy clinician, a simplified diagnostic algorithm for PH that is relevant for making a correct early diagnosis and limiting the impact of PH
Availability, cost and affordability of essential cardiovascular disease medicines in the south west region of Cameroon: Preliminary findings from the Cameroon science for disease study.
BACKGROUND:More than 80% of premature deaths due to cardiovascular disease (CVD) occur in low- and middle-income countries. However, access to, and affordability of medications remain a challenge in these countries. OBJECTIVE:To assess the availability, cost and affordability of essential cardiovascular medicines in the South West region of Cameroon. METHODS:In an audit of 63 medicine outlets, twenty-six essential medicines were surveyed using the World Health Organisation (WHO) /Health Action International methodology. Availability, costs and the ratio of the median price to the international reference price were evaluated in public, confessional, private facility medicine outlets, and community pharmacies. Affordability was assessed by calculating the number of days' wages it will cost the lowest-paid unskilled government worker to purchase a month worth of chronic treatment. FINDINGS:Availability ranged from 25.3% (public facility outlets) to 49.2% (community pharmacies) for all medicines. This was higher in urban and semi-urban compared to rural outlets. Cost of medicines was highest in community pharmacies and lowest in public facility outlets. Aspirin, digoxin, furosemide, hydrochlorothiazide and nifedipine were affordable (cost a day's wage or less). Medicines for heart failure and dyslipidaemia (beta blockers, angiotensin converting enzyme inhibitors and statins) required 2-5 days and 6-13 days wages respectively for one month of chronic treatment. CONCLUSION:Overall availability of CVD essential medicines was lower than WHO recommendations, and medicines were largely unaffordable. While primary prevention is pivotal, improving availability and affordability of medicines especially for public facilities would provide additional benefit in curbing the CVD burden
Pulmonary hypertension as seen in a rural area in sub-Saharan Africa: high prevalence, late clinical presentation and a high short-term mortality rate during follow up
Introduction: The epidemiology of pulmonary hypertension (PH) in low- to middle-income countries is poorly characterised. We assessed the prevalence, baseline characteristics and mortality rate in patients with echocardiographically diagnosed PH at a rural cardiac centre in Cameroon. Methods: We conducted a prospective cohort study in a subsample of 150 participants, aged 18 years and older, diagnosed with PH [defined as right ventricular systolic pressure (RVSP) ≥ 35 mmHg in the absence of pulmonary stenosis and right heart failure]. PH was classified as mild (RVSP: 35–50 mmHg), moderate (RVSP: 51–60 mmHg) and severe (RVSP: > 60 mmHg). Results: Of 2 194 patients screened via echocardiograms, 343 (crude prevalence 15.6%) had PH. The sub-sample of 150 patients followed up (54.7% women, mean age of 62.7 ± 18.7 years) had a mean RVSP of 68.6 mmHg. They included 7.3% mild, 29.3% moderate and 63.4% severe PH cases. Co-morbidities included log smoke (80.7%), hypertension (52.0%), family history of cardiovascular disease (50.0%), diabetes (31.3%), alcohol abuse (21.3%) and HIV infection (8.7%). Main clinical features were dyspnoea (78.7%), fatigue (76.7%), palpitations (57.3%), cough (56.7%), jugular venous distension (68%) and peripheral oedema (66.7%). Overall, 70% presented in World Health Organisation functional class III/IV. PH due to left heart disease (PHLHD) was the commonest (64.7%), and rheumatic valvular disease accounted for 36.1%. The six-month mortality rate was 28%. Conclusion: PH, dominated by PHLHD, was common among adults attending this rural centre and was associated with a high mortality rate. Related co-morbidities and late clinical presentation reflect the poor socio-economic context. Improved awareness of PH among physicians could promote early diagnosis and management
Infantile hypertrophic pyloric stenosis: a 4-year experience from two tertiary care centres in Cameroon
Abstract Objective This study aimed to describe the clinical characteristics of patients with infantile hypertrophic stenosis, management and its outcome in two tertiary care centres in Cameroon. Results A total of 21 patients were included from the two centres. The mean age at presentation was 5.2 ± 1.2 weeks, predominantly male with a male-to-female ratio of 4.25:1. The triad of vomiting, visible peristalsis and palpable mass was present in only 7 (33.3%) of the participants. The diagnosis was confirmed with ultrasounds in all participants. Ramstedt pyloromyotomy was done in all participants and in 9.5% of the participants it was complicated by intra-operative duodenal perforation whereas in the postoperative period the most common complications were vomiting (6, 28.6%), sepsis (2, 9.5%), and paralytic ileus (2, 9.5%). The mortality rate from the series is 9.5%. According to univariate logistic regression: severe dehydration [OR = 5.41, 95% CI = (3.11–6.97), p = 0.002], hypokalaemia [OR = 2.63, 95% CI = (1.02–5.91), p = 0.042] and surgical site infection [OR = 3.12, 95% CI (1.22–5.64), p = 0.023] were the main predictors of mortality whereas postoperative hospital length of stay > 5 days was significantly associated with surgical site infection [OR = 2.44, 95% CI = (1.12–6.44), p = 0.002] and postoperative nausea and vomiting [OR = 3.64, 95% CI = (1.18–6.64), p = 0.022]
