Hormonal contraception,sexual behaviour and HIV prevalence among women in Cameroon

Background  

Data on the effect of contraceptive methods, other than the condom, on HIV acquisition is not clear. The aim of this study was to describe hormonal contraceptive use, sexual behaviour and HIV prevalence among women in Cameroon in order to provide baseline information for future analytical studies.     

Dual Pathology in a Patient with Right Lower Quadrant Pain

Meckel diverticula are remnants of the omphalomesenteric duct. They have 2% incidence in the general population, are usually asymptomatic, and tend to be diagnosed incidentally. The generally held principle had been that asymptomatic cases do not require resection, as exemplified by a 2008 systematic review of over 200 studies. However, a recent series reported an increased risk of malignancies, and recommended mandatory resection. We present a case of Meckel diverticulitis with concurrent infiltrative appendiceal carcinoid in a patient with right lower quadrant pain.     

Setting-Level Influences on Implementation of the Responsive Classroom Approach

We used mixed methods to examine the association between setting-level factors and observed implementation of a social and emotional learning intervention (Responsive Classroom® approach; RC). In study 1 (N?=?33 3rd grade teachers after the first year of RC implementation), we identified relevant setting-level factors and uncovered the mechanisms through which they related to implementation. In study 2 (N?=?50 4th grade teachers after the second year of RC implementation), we validated our most salient Study 1 finding across multiple informants. Findings suggested that teachers perceived setting-level factors, particularly principal buy-in to the intervention and individualized coaching, as influential to their degree of implementation. Further, we found that intervention coaches’ perspectives of principal buy-in were more related to implementation than principals’ or teachers’ perspectives. Findings extend the application of setting theory to the field of implementation science and suggest that interventionists may want to consider particular accounts of school setting factors before determining the likelihood of schools achieving high levels of implementation.     

Cardiac risk factors and risk scores vs cardiac computed tomography angiography: a prospective cohort study for triage of ED patients with acute chest pain

ObjectiveThe objective of the study is to evaluate cardiac risk factors and risk scores for prediction of coronary artery disease (CAD) and adverse outcomes in an emergency department (ED) population judged to be at low to intermediate risk for acute coronary syndrome.MethodsInformed consent was obtained from consecutive ED patients who presented with chest pain and were evaluated with coronary computed tomography angiography (cCTA). Cardiac risk factors, clinical presentation, electrocardiogram, and laboratory studies were recorded; the Thrombolysis in Myocardial Infarction (TIMI) and Global Registry of Acute Coronary Events (GRACE) scores were tabulated. Coronary computed tomography angiography findings were rated on a 6-level plaque burden scale and classified for significant CAD (stenosis ≥ 50%). Adverse cardiovascular outcomes were recorded at 30 days.ResultsAmong 250 patients evaluated by cCTA, 143 (57%) had no CAD, 64 (26%) demonstrated minimal plaque (< 30% stenosis), 26 (10%) demonstrated mild plaque (< 50% stenosis), 9 (4%) demonstrated moderate single vessel disease (50%-70% stenosis), 2 (1%) demonstrated moderate multivessel disease, and 6 (2%) demonstrated severe disease (> 70% stenosis). Six patients developed adverse cardiovascular outcomes. Among traditional cardiac risk factors, only age (older) and sex (male) were significant independent predictors of CAD. Correlation with CAD was poor for the TIMI (r = 0.12) and GRACE (r = 0.09-0.23) scores. The TIMI and GRACE scores were not useful to predict adverse outcomes. Coronary computed tomography angiography identified severe CAD in all subjects with adverse outcomes.ConclusionAmong ED patients who present with chest pain judged to be at low to intermediate risk for acute coronary syndrome, traditional risk factors are not useful to stratify risk for CAD and adverse outcomes. Coronary computed tomography angiography is an excellent predictor of CAD and outcome.     

The effect of electric stimulation treatment on the functional rehabilitation of acute geriatric patients with stroke--a preliminary study

The most common neurological damage in acute stroke/cerebrovascular accident (CVA) is a decline in the senso-motor capacities of both the upper and the lower extremities with a more severe injury in the upper ones. Motor improvement of the affected limb can be attained through frequent intensive exercise by electrical stimulation (ES). The objective of this study was to examine the effect of the ES treatment using Handmaster ES device on the functional rehabilitation of elderly patients after acute CVA. Twenty-two elderly with different levels of damage and partial movements in their upper limb joints underwent a 3-week treatment. Nine of them were treated for additional 3-weeks after a 3-week break. After the first 3-week treatment, significant improvements were observed, in all the subjects, in the active range of motion (ROM) of the shoulder and the wrist joints, on manual dexterity tests and on functional independence measure (FIM). After the two periods of treatment the nine subjects exhibited significant improvements in ROM and in manual dexterity. FIM score increased by the same rate after each of the three stages. This preliminary study has proven that the Handmaster treatment can improve the geriatric rehabilitation outcome of elderly patients with senso-motor deficit caused by acute CVA.     

The risk of cholecystectomy for acute cholecystitis in diabetic patients.

In order to evaluate the risk of acute cholecystitis in diabetic patients, we analyzed 2,700 consecutive cholecystectomies, 566 of which were performed in the presence of acute cholecystitis. Of these patients 123 had diabetes mellitus (DM) and 433 had no diabetes (ND). The aim of this study was to establish the comparative risks in the two groups. We found that diabetics are more likely to be operated on in the acute stage of their disease (22% vs. 12%). The DM group had a higher rate of septic bile, gangrenous changes and perforations of the gallbladder wall. The morbidity rate was higher in the DM group (21% vs. 9%), and mortality was slightly higher in the DM group. The degree of additional operative risk does not in our view justify recommending cholecystectomy in diabetic patients with asymptomatic gallstones. Early surgery however, is highly recommended in diabetics with symptomatic gallstones and acute cholecystitis.
