Effects of COVID-19 Pandemic on Voluntary Medical Male Circumcision Services for HIV Prevention, Sub-Saharan Africa, 2020.

Beginning in March 2020, to reduce COVID-19 transmission, the US President's Emergency Plan for AIDS Relief supporting voluntary medical male circumcision (VMMC) services was delayed in 15 sub-Saharan African countries. We reviewed performance indicators to compare the number of VMMCs performed in 2020 with those performed in previous years. In all countries, the annual number of VMMCs performed decreased 32.

A Systematic Review of CBM Professional Development Materials: Are Teachers Receiving Sufficient Instruction in Data-Based Decision-Making?

The purpose of this study was to examine the amount of attention devoted to data-based decision-making in Curriculum-Based Measurement (CBM) professional development materials. Sixty-nine CBM instructional sources were reviewed, including 45 presentations, 22 manuals, and two books. The content of the presentations and manuals/books was coded into one of four categories: (a) general CBM information, (b) conducting CBM, (c) data-based decision-making, and (d) other.

Sexual and Gender-Based Violence Attitudes and Experiences among Nine Sub-Saharan African Militaries.

Introduction: While sexual and gender-based violence (SGBV) is recognized as an important factor driving the HIV epidemic in sub-Saharan Africa, attitudes toward and prevalence of SGBV within sub-Saharan African military populations are unknown. Data on SGBV were collected from military service members of nine sub-Saharan African militaries. Attitudes related to SGBV and characteristics of those who commit and experience SGBV are reported.

Role of malnutrition and parasite infections in the spatial variation in children's anaemia risk in northern Angola.

Anaemia is known to have an impact on child development and mortality and is a severe public health problem in most countries in sub-Saharan Africa. We investigated the consistency between ecological and individual-level approaches to anaemia mapping by building spatial anaemia models for children aged ≤15 years using different modelling approaches. We aimed to (i) quantify the role of malnutrition, malaria, Schistosoma haematobium and soil-transmitted helminths (STHs) in anaemia endemicity; and (ii) develop a high resolution predictive risk map of anaemia for the municipality of Dande in northern Angola.

Hypertension in Northern Angola: prevalence, associated factors, awareness, treatment and control.

Background: Seventy-five million people are estimated to be hypertensive in sub-Saharan Africa. This translates in high morbidity and mortality, as hypertension is now considered to be the number one single risk factor for death worldwide. Accurate data from countries lacking national disease surveillance is needed to guide future evidence-driven health policies.

Finding malaria hot-spots in northern Angola: the role of individual, household and environmental factors within a meso-endemic area.

Background: Identifying and targeting hyper-endemic communities within meso-endemic areas constitutes an important challenge in malaria control in endemic countries such like Angola. Recent national and global predictive maps of malaria allow the identification and quantification of the population at risk of malaria infection in Angola, but their small-scale accuracy is surrounded by large uncertainties. To observe the need to develop higher resolution malaria endemicity maps a predictive risk map of malaria infection for the municipality of Dande (a malaria endemic area in Northern Angola) was developed and compared to existing national and global maps, the role of individual, household and environmental risk factors for malaria endemicity was quantified and the spatial variation in the number of children at-risk of malaria was estimated.

Cross-sectional pilot study about the health status of diabetic patients in city of Misurata, Libya.

Background: Being a leading cause of death worldwide, epidemiological studies about diabetes mellitus have encouraged governments to initiate or improve local diabetes monitoring and prevention strategies.

Objective: The main objective of this study was to examine the profile of diabetic patients in the city of Misurata, the third largest city in Libya.

Methods: 260 diabetic cases of both gender randomly selected from the total number of patients admitted to the centre of diabetes and endocrine disorders, Misurata -Libya for the period between January to March 2008.

Epidemiology of malaria, schistosomiasis, geohelminths, anemia and malnutrition in the context of a demographic surveillance system in northern Angola.

Background: Malaria, schistosomiasis and geohelminth infection are linked to maternal and child morbidity and mortality in sub-Saharan Africa. Knowing the prevalence levels of these infections is vital to guide governments towards the implementation of successful and cost-effective disease control initiatives.

Methodology/principal Findings: A cross-sectional study of 1,237 preschool children (0-5 year olds), 1,142 school-aged children (6-15 year olds) and 960 women (>15 year olds) was conducted to understand the distribution of malnutrition, anemia, malaria, schistosomiasis (intestinal and urinary) and geohelminths in a north-western province of Angola.

Spectrophotometry of hydroxocobalamin and hemoglobin reveals production of an unanticipated methemoglobin variant.

Introduction: Cyanide-poisoned patients often require pulse oximetry and co-oximetry to measure oxyhemoglobin, deoxyhemoglobin, carboxyhemoglobin, and methemoglobin. These and other critical laboratory measurements can be confounded by the cyanide antidote hydroxocobalamin. The postulated mechanism of this confounding is direct optical interference.

Effect of a yellow filter on contrast sensitivity and disability glare after laser in situ keratomileusis under mesopic and photopic conditions.

Purpose: To analyze the effect of a yellow filter on contrast sensitivity and disability glare under mesopic and photopic luminance conditions in laser in situ keratomileusis (LASIK) patients and control subjects.

Methods: Contrast sensitivity with and without glare was determined in 27 patients who had undergone LASIK at least 1 year previously and in 30 control subjects. Tests were performed with and without a coated yellow filter (X-482 nm cut-off) using the Mesotest II or Mesoptometer II (Oculus, Wetzlar, Germany) under mesopic conditions, and the Contrast Glaretester 1000 (Takagi, Seiko Co Ltd, Nagano, Japan) under photopic conditions.

Effect of a yellow filter on mesopic contrast perception and differential light sensitivity in the visual field.

Purpose: Previous studies on the effects of yellow filters in the visual performance have been carried out, presenting discrepancies among the different investigations. Our study reports the influence of the yellow filter without residual reflections on contrast perception and differential light sensitivity (DLS) under mesopic conditions.

Methods: Contrast sensitivity, low contrast visual acuity and luminance thresholds in the central visual field (30 degrees ) were measured in a group of 38 adult subjects with and without a coated yellow lens (482-nm cut-off) under mesopic conditions.

Heartwater (Cowdria ruminantium infection) as a cause of postrestocking mortality of goats in Mozambique.

A serological survey in Mozambique to detect antibodies to Cowdria ruminantium, the etiologic agent of heartwater, revealed a seroprevalence of 8.1% (n = 332) for goats in the northern province of Tete and of 65.6% (n = 326) for goats in the southern provinces.

Identifying hazardous or harmful alcohol use in medical admissions: a comparison of audit, cage and brief mast.

Two hundred and forty new medical inpatients received Alcohol Use Disorders Identification Test (AUDIT), CAGE and brief Michigan Alcoholism Screening Test (brief MAST) questionnaires. Sensitivities when identifying weekly drinkers of > 14 units (women) or > 21 units (men) were 93, 79 and 35%, respectively (P < 0.001).

Mortality in a hospitalized mentally handicapped population: a 10-year survey.

The mortality experiences of a hospitalized mentally handicapped population between 1981 and 1990 (inclusive) were examined. A continued trend for increasing longevity in both males and females was found, with mean ages at death now approaching those in the general population. The commonest cause of death was non-tubercular respiratory infection, from which patients were particularly at risk during the months of December to February (inclusive).

Antibodies to Cowdria ruminantium in Mozambican goats and cattle detected by immunofluorescence using endothelial cell culture antigen.

Endothelial cell cultures, established from bovine umbilical cord arteries and subsequently infected with Cowdria ruminantium, were used as antigen in the indirect fluorescent antibody test. Bovine sera (374) and caprine sera (388) collected in 6 provinces of Mozambique were tested. Overall, 30.

Volatile substance abuse: a brief report.

Volatile substance abuse (VSA) is on the increase: the practice is widespread among young people and concern has often been expressed about its potential dangers. It is estimated that in the United Kingdom between 3.5-10% of current adolescents have at least experimented with solvents, and up to 1% of the secondary school population are currently abusers.

The clinical efficacy of maintenance electroconvulsive therapy in a patient with a mild mental handicap.

A 32-year-old chronically relapsing depressed male patient with a mild mental handicap had tried different forms of pharmacotherapy which were either not tolerated or failed to prevent recurrences of episodes of psychotic depression. The use of maintenance ECT as the mainstay of the therapeutic regime led to a marked consistent clinical improvement.
