Adherence to antidiabetic medication and factors associated with non-adherence among patients with type-2 diabetes mellitus in two regional hospitals in Cameroon.

BACKGROUND: Diabetes mellitus is a growing cause of disease burden globally. Its management is multifaceted, and adherence to pharmacotherapy is known to play a significant role in glycaemic control. Data on medication adherence among affected patients is unknown in Cameroon. In this study, the level of adherence and factors influencing non-adherence to antidiabetic medication among patients with type-2 diabetes was assessed. METHODS: A hospital-based cross-sectional study among adult patients receiving care in the diabetic clinics of the Limbe and Bamenda Regional Hospitals in Cameroon was conducted. Medication adherence was assessed using the Medication Compliance Questionnaire (MCQ). Factors associated with non-adherence to medication were determined using basic and adjusted multivariable logistic regression models. RESULTS: A total of 195 patients with type 2 diabetes were recruited. The prevalence of non-adherence to medication was 54.4% [95% confidence interval (CI): 47.1-61.5%]. In multivariable analysis, age > 60 years (aO.R. = 0.48, 95% CI: 0.25-0.94), alcohol consumption (aO.R. = 2.13, 95% CI: 1.10-4.14) and insulin alone therapy (aO.R. = 2.85, 95% CI: 1.01-8.08) were associated with non-adherence. Patients attributed their non-adherence to forgetfulness (55.6%), lack of finances (38.2%) and disappearance of symptoms (14.2%). CONCLUSIONS: Adherence to anti-diabetic medication is poor in this study with more than half of participants being non-adherent. Urgent interventions are required to tackle this problem in combined efforts to stem this looming diabetes epidemic.

Prevalence and factors associated with depression among medical students in Cameroon: a cross-sectional study.

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.

Population awareness of cardiovascular disease and its risk factors in Buea, Cameroon.

BACKGROUND: Adequate awareness of cardiovascular diseases (CVD) and their risk factors may help reduce the population's exposure to modifiable risk factors and thereby contribute to prevention and control strategies. There is limited data on knowledge among the general population in sub-Saharan Africa regarding CVD and risk factors. We aimed to assess the population awareness (and associated factors) of CVD types and risk factors in Buea, Cameroon. METHODS: This was a community-based cross-sectional study conducted in 2016 among randomly selected adults (>18 years). Data on socio-demographic characteristics, knowledge about CVD types, their risk factors and warning signs for CVD events (stroke and heart attack) were acquired using a self-administered questionnaire. Logistic regression analysis was used to investigate factors associated with moderate-to-good knowledge. RESULTS: Of the 1162 participants (61.7% women, mean age 32 years), 52.5% had overall poor knowledge (mean score 12.1 on total of 25) on CVD with only about a quarter correctly identifying types of CVD. Overall, 36, 63 and 45% were unaware of CVD risk factors, warning signs of heart attack and stroke respectively. In multivariable analysis; high level of education (aOR = 2.26 (1.69-3.02), p < 0.0001), high monthly income (aOR = 1.64 (1.07-2.51), p = 0.023), having a family history of CVD (aOR = 1.59 (1.21-2.09), p = 0.001) and being a former smoker (aOR = 1.11 (1.02-1.95), p = 0.043) were associated with moderate-to-good knowledge. CONCLUSIONS: There exists a significant gap in population awareness about CVDs in Cameroon and this is similar to previous reports. Cost-effective community health education interventions taking into account socioeconomic status may be beneficial in this setting.

Awareness and low uptake of post exposure prophylaxis for HIV among clinical medical students in a high endemicity setting.

BACKGROUND: Adequate knowledge and practices on post exposure prophylaxis (PEP) for HIV among health care providers are crucial for HIV prevention. However there is limited data on PEP knowledge and practice from developing countries where the burden of HIV infection continues to increase. We assessed the knowledge of clinical medical students on PEP, their practices in response to occupational exposure to HIV, as well as the determinants of good knowledge on PEP. METHODS: A cross-sectional study was conducted in November 2014 involving 154 consecutively recruited clinical medical students (4(th)-6(th) year undergraduates). Data were acquired using a structured questionnaire. Knowledge on PEP was assessed using a questionnaire comprising 25 questions and categorized as: good (20 or more correct answers), moderate (13-19 correct answers) and poor (12 or fewer correct answers). RESULTS: For the 154 students included (57.8 % being male), the mean age was 23.2 ± 2.4 years, and 89 % had heard about PEP for HIV. The majority of students had moderate (61.7 %) and poor (32.5 %) knowledge on PEP. Overall knowledge score increased with increasing level of studies (p < 0.05). Only 10 (6.5 %) had had previous training on PEP, most of whom were senior level students (p = 0.01). Fifty-four students (35.1 %) knew the appropriate duration of PEP and this awareness increased with level of studies (p = 0.001). Of the 81 (52.6 %) who reported occupational exposure to HIV in the past, only 4 (4.9 %) received PEP. CONCLUSIONS: Overall, knowledge on PEP among clinical medical students in this setting was non-optimal with very low uptake PEP. Intensification of HIV curricula to involve PEP as well as continuous medical education programs and workshops are potential avenues to improve awareness in this vulnerable population.

Burnout as a correlate of depression among medical students in Cameroon: a cross-sectional study.

OBJECTIVE: Burnout syndrome has been shown to mediate the pathway between job stress and depression. This study aims to assess the relationship between the various components of burnout syndrome and depression; and to determine the contribution of other sociodemographic variables to depression among medical students in Cameroon. DESIGN: A cross-sectional study. SETTING: Three of the five medical schools in Cameroon with students in both preclinical and clinical levels of studies. PARTICIPANTS: The study included 413 consenting medical students. PRIMARY OUTCOME MEASURE: Data were collected via a printed self-administered questionnaire. The primary outcome-depression was assessed using the Patient Health Questionnaire-9 (PHQ-9). Burnout was assessed using the Oldenburg Burnout Inventory. Multivariable linear regression was used to identify independent correlates of depression. RESULTS: The overall prevalence of depression (PHQ-9 >4) and major depressive disorder (PHQ-9 >9) in these students was 66.34% and 23.00%, respectively. After multivariable linear regression analysis, four variables-total OLBI (beta=0.32; 95% CI 0.22 to 0.42; p<0.001); number of children (beta=-2.26; 95% CI -3.70 to -0.81; p=0.002); occurrence of a life-changing crises (beta=1.29; 95% CI 0.13 to 2.45; p=0.029) and presence of a chronic illness (beta=3.19; 95% CI 0.96 to 5.42; p=0.005) significantly predicted depression in these students and explained 32.4% of the variance (R2=32.4, F[14, 204]=6.98, p<0.001). The emotional exhaustion component (R2=17.4, F[1, 411]=86.39, p<0.001) explained more of the variance in depression than the disengagement component (R2=6.1, F[1, 411]=26.76, p<0.001) of burnout syndrome. CONCLUSION: The prevalence of depression among medical students in Cameroon is high. It is important that correlates of depression are identified early in medical students to limit progress to depression.

Association between CD4 Cell Count and Blood Pressure and Its Variation with Body Mass Index Categories in HIV-Infected Patients.

The aim of this study was to establish whether an independent relationship exists between CD4 count and hypertension and if this relationship is modified or confounded by the body mass index (BMI). Methods. A secondary data analysis of a cross-sectional study on 200 HIV/AIDS patients at a referral hospital in Cameroon was conducted. Linear and logistic regression models were used as appropriate to explore the association between the variables of interest. Results. There was no linear association between log CD4 count and both systolic (p = 0.200; r = 0.12) and diastolic blood pressures (p = 0.123; r = 0.14), respectively. After adjusting for BMI, patients with CD4 count ≥ 350 cells/µl were more likely to have hypertension than those with CD4 count < 350 cells/µl (AOR: 2.50, 95% CI: 1.05-5.93, and p = 0.032). There was no effect modification from BMI (test of homogeneity, p = 0.721). There was no independent relationship between CD4 count and hypertension after controlling for age, sex, family history of hypertension, BMI-defined overweight, HAART use, and duration of HIV infection (AOR: 1.66, 95% CI: 0.48-5.71, and p = 0.419). Conclusion. This study did not identify any independent relationship between CD4 count and hypertension. Large prospective studies are recommended to better explore this relationship between hypertension and CD4 count.

Blighted ovum and tubal pregnancy: a rare form of heterotopic pregnancy: case report.

BACKGROUND: Heterotopic pregnancies are rare in spontaneous conceptions. Nonetheless, when it does occur, the intrauterine pregnancy is usually viable. We herein present a true rarity of the coexistence of a blighted ovum and an ectopic pregnancy. CASE PRESENTATION: A 25 year old G2P1001 married seamstress of African ethnicity at 8 weeks of amenorrhoea presented to our health facility with a 4 day history of lower abdominal pains and vaginal bleeding for which physical examination revealed a closed cervix. Trans-abdominal ultrasound scan confirmed a diagnosis of a blighted ovum and an ectopic pregnancy. Patient was managed with surgical therapy. Evolution thereafter was uneventful. CONCLUSION: The case presented confirms that HP can occur in the absence of predisposing factors, and that the detection of a blighted ovum should not preclude the possibility of a simultaneous ectopic pregnancy. A high index of suspicion could lead to early diagnosis, prompt management and a favourable prognosis even in a low-income setting.

Prevalence, Clinical Presentation, and Factors Associated With Diabetic Foot Ulcer in Two Regional Hospitals in Cameroon.

This study aimed to determine the prevalence of diabetic foot ulcer and high risk for ulceration, describe the clinical presentation, and identify factors associated with diabetic foot ulcer in the Southwest regional hospitals of Cameroon. In this cross-sectional study, data were collected using a structured questionnaire administered to consecutive patients with diabetes. Findings from detailed foot examination were recorded. Diabetic foot ulcer was diagnosed according to the International Working Group on Diabetic Foot (IWGDF) definition. Data were analyzed with Stata IC version 12. Of the 203 participants included, 63.1% were females. Age ranged from 26 to 96 years. The median duration of diabetes was 4.0 years (interquartile range 1.0-8.0 years). The prevalence of diabetic foot ulcer was 11.8% (24), of whom 29.2% (7) had high grade (grades 2 to 4), and most of the ulcers 58.3% (14) were located at the plantar region. The prevalence of high risk for ulceration was 21.8% (39). Loss of protective sensation (OR = 3.73, 95% CI = 1.43-9.71; P = .007), and peripheral arterial disease (OR = 3.48, 95% CI = 1.14-10.56; P = .028) were independently associated with diabetic foot. Diabetic foot ulcer is a common complication among patients with diabetes attending these regional hospitals. Loss of protective sensation, and peripheral arterial disease increase the odds of having diabetic foot ulcer, and we suggest them as the main target of interest for prevention.

Prevalence of maternal HIV infection and knowledge on mother-to-child transmission of HIV and its prevention among antenatal care attendees in a rural area in northwest Cameroon.

BACKGROUND: In 2010, an estimated 141 new HIV infections occurred per day in Cameroon and reports suggest an upsurge of these rates by 2020 if current trends continue. Mother-to-child transmission (MTCT) of HIV is a major public health challenge, and maternal knowledge on HIV transmission during pregnancy and its prevention is important in curtailing paediatric HIV acquisition. OBJECTIVES: We aimed at establishing the prevalence of maternal HIV infection as well as assessing knowledge on HIV, MTCT and prevention of MTCT (PMTCT) of HIV among pregnant women in a rural area of Cameroon. METHODS: This study was conducted in two phases: a 29 month retrospective analysis of 1866 deliveries within three rural health facilities in the Babessi sub-division, Northwest Cameroon and a 1 month prospective phase wherein 150 consenting pregnant women attending antenatal care (ANC) at the study centres were consecutively recruited. RESULTS: Overall, the prevalence of maternal HIV infection was 5.0% (100/2016). All (100%) of the interviewed pregnant women were aware of HIV infection and most (76.7%) had adequate knowledge on its routes of transmission. Meanwhile, only 79.3% (119/150) of them were aware of MTCT with slightly above a third (37.0%) having adequate knowledge on the periods of transmission. The proportions of women correctly stating: during pregnancy, during labour/delivery and during breastfeeding as possible periods of MTCT of HIV were 63.0%, 60.5% and 89.1% respectively. A majority (76.3%) of these women had inadequate knowledge on PMTCT of HIV. CONCLUSION: The overall prevalence of maternal HIV warrants strengthening of current intervention strategies including scaling-up of PMTCT measures. Among others, intensification of HIV-related ANC services to improve the pregnant women's awareness and knowledge on MTCT and its prevention are vital steps in curbing the growing burden of paediatric HIV.
