Minimally destructive hDNA extraction method for retrospective genetics of pinned historical Lepidoptera specimens.

The millions of specimens stored in entomological collections provide a unique opportunity to study historical insect diversity. Current technologies allow to sequence entire genomes of historical specimens and estimate past genetic diversity of present-day endangered species, advancing our understanding of anthropogenic impact on genetic diversity and enabling the implementation of conservation strategies. A limiting challenge is the extraction of historical DNA (hDNA) of adequate quality for sequencing platforms.

Prognostic values of modifiable risk factors for cardiovascular events in South African health promotion.

Background: Cardiovascular diseases (CVDs) are increasing at an alarming rate among the South African population. This study aimed to determine the prognostic value of modifiable CVD risk factors for fatal and non-fatal events to inform cardiovascular health promotion practices in the South African public health system.

Methods: Data was collected from individuals participating in the South African leg of a multi-national prospective cohort study.

The Immediate Effect of African Drumming on the Mental Well-Being of Adults With Mood Disorders: An Uncontrolled Pretest-Posttest Pilot Study.

Objective: This pilot study is the first to examine the effects of an occupational therapist-led African drumming group on mental well-being among adult psychiatric inpatients with mood disorders.

Method: We used a quasi-experimental, uncontrolled, one-group, pretest-posttest design. We collected data for six different drumming groups (N = 13) using the Stellenbosch Mood Scale, the Primary Health Questionnaire-9, the Generalized Anxiety Disorder-7 scale, and the Enjoyment of Interaction Scale.

HIV stigma experiences and stigmatisation before and after a HIV stigma-reduction community "hub" intervention.

This study sought to explore, describe and determine whether an HIV stigma-reduction community "hub" intervention would change the HIV stigma experiences of people living with HIV (PLWH) and the stigmatisation by the community in an urban area in South Africa. A convergent parallel mixed-method design with a single case pre-test post-test design and an interpretive description approach was utilised. The sample for this study included 62 PLWH recruited through accessibility sampling and 570 community members recruited through random voluntary sampling.

Psychosocial well-being of people living with HIV and the community before and after a HIV stigma-reduction community "hub" network intervention.

The purpose of the research was to determine whether an HIV stigma-reduction community "hub" network intervention in a South African urban area would bring about a difference in the psychosocial well-being of people living with HIV (PLWH), as well as their community (living in the same municipal ward). A single case pre-test post-test design was implemented. The sample for this study included 62 PLWH who were selected through accessibility sampling and 570 community members who were selected through random voluntary sampling.

Phronesis: Beyond the Research Ethics Committee-A Crucial Decision-Making Skill for Health Researchers During Community Research.

Health researchers conducting research in the community are often faced with unanticipated ethical issues that arise in the course of their research and that go beyond the scope of ethical approval by the research ethics committee. Eight expert researchers were selected through extreme intensity purposive sampling, because they are representative of unusual manifestations of the phenomenon related to their research in the community. They were selected to take part in a semi-structured focus group discussion on whether practical wisdom (phronesis) is used as a decision-making skill to solve unanticipated ethical issues during research in the community.

A Community "Hub" Network Intervention for HIV Stigma Reduction: A Case Study.

We describe the implementation of a community "hub" network intervention to reduce HIV stigma in the Tlokwe Municipality, North West Province, South Africa. A holistic case study design was used, focusing on community members with no differentiation by HIV status. Participants were recruited through accessibility sampling.

Changeover-time in psychosocial wellbeing of people living with HIV and people living close to them after an HIV stigma reduction and wellness enhancement community intervention.

HIV stigma continues to affect the psychosocial wellbeing of people living with HIV (PLWH) and people living close to them (PLC). Literature unequivocally holds the view that HIV stigma and psychosocial wellbeing interact with and have an impact on each other. This study, which is part of a larger research project funded by the South Africa Netherlands research Programme on Alternatives in Development (SANPAD), responds to the lack of interventions mitigating the impactful interaction of HIV stigma and psychosocial wellbeing and tests one such intervention.

A comparison of the cardiometabolic profile of black South Africans with suspected non-alcoholic fatty liver disease (NAFLD) and excessive alcohol use.

Excessive alcohol use and non-alcoholic fatty liver disease (NAFLD) are putative cardiovascular disease risk factors. In order to ease the identification of these conditions on primary health care level, we aimed to determine and compare the demographic and cardiometabolic characteristics of excessive alcohol users and those with suspected NAFLD in black South Africans. In the Prospective Urban Rural Epidemiology study (North West Province, South Africa, N = 2021, collected in 2005) we selected 338 participants, namely: 1) alcohol users (N = 143) reporting 'yes' to alcohol intake, with high gamma-glutamyl transferase (GGT) ≥80 U/L and a percentage carbohydrate deficient transferrin (%CDT) ≥2%; 2) non-alcohol users (N = 127) self-reporting 'no' to alcohol intake with GGT ≤30 U/L and %CDT ≤2%; and 3) NAFLD group (N = 68) who were non-drinkers with GGT levels ≥60 U/L and %CDT ≤ 2%.

Psychological distress and the development of hypertension over 5 years in black South Africans.

Alarming increases in the incidence of hypertension in many low- and middle-income countries are related to alcohol overuse. It is unclear whether alcohol overuse is a symptom of psychological distress. The authors assessed psychological distress in Africans and its relationship with a 5-year change in blood pressure (BP), independent of alcohol intake.

Health behaviour change of people living with HIV after a comprehensive community-based HIV stigma reduction intervention in North-West Province in South Africa.

Abstract All over the world, health behaviour is considered a complex, far reaching and powerful phenomenon. People's lives are influenced by their own or others' health behaviour on a daily basis. Whether it has to do with smoking, drinking, pollution, global warming or HIV management, it touches lives and it challenges personal and community responses.

Experiences of people living with HIV and people living close to them of a comprehensive HIV stigma reduction community intervention in an urban and a rural setting.

HIV stigma remains high globally. Although there is a selection of HIV stigma reduction interventions discussed in the literature, there is a paucity of research about the effectiveness of these interventions. This study aimed at gaining a deeper understanding of the experiences of people living with HIV (PLWH) and people living close to them from six designated groups during and after having undergone a comprehensive HIV stigma reduction community intervention in both an urban and a rural setting.

A comprehensive HIV stigma-reduction and wellness-enhancement community intervention: a case study.

We describe the implementation of a comprehensive HIV stigma-reduction and wellness-enhancement community intervention that focused on people living with HIV (PLWH), as well as people living close to them (PLC) from six designated groups. A holistic multiple case study design was used in urban and rural settings in the North West Province, South Africa. Purposive voluntary sampling was used to recruit the PLWH group; snowball sampling was used for the PLCs.

Relationship of coagulation and fibrinolytic variables with arterial structure and function in Africans.

Introduction: Although both coagulation and fibrinolysis are associated with cardiovascular disease (CVD) the underlying nature and pathways of many of these associations are still unclear. Our aim was to determine which of the current or 5-year prior levels of total fibrinogen, fibrinogen γ', plasminogen activator inhibitor-1 (PAI-1act) and global fibrinolytic potential were the stronger determinant of arterial structure and function.

Materials And Methods: This prospective study consisted of 2010 Africans over the age of 35 years with 5-year follow-up data available for 1288 participants.

Community care workers, poor referral networks and consumption of personal resources in rural South Africa.

Although home-based care (HBC) programs are widely implemented throughout Africa, their success depends on the existence of an enabling environment, including a referral system and supply of essential commodities. The objective of this study was to explore the current state of client referral patterns and practices by community care workers (CCWs), in an evolving environment of one rural South African sub-district. Using a participant triangulation approach, in-depth qualitative interviews were conducted with 17 CCWs, 32 HBC clients and 32 primary caregivers (PCGs).

Evaluation of waist-to-height ratio to predict 5 year cardiometabolic risk in sub-Saharan African adults.

Background And Aims: Simple, low-cost central obesity measures may help identify individuals with increased cardiometabolic disease risk, although it is unclear which measures perform best in African adults. We aimed to: 1) cross-sectionally compare the accuracy of existing waist-to-height ratio (WHtR) and waist circumference (WC) thresholds to identify individuals with hypertension, pre-diabetes, or dyslipidaemia; 2) identify optimal WC and WHtR thresholds to detect CVD risk in this African population; and 3) assess which measure best predicts 5-year CVD risk.

Methods And Results: Black South Africans (577 men, 942 women, aged >30years) were recruited by random household selection from four North West Province communities.

Urinary albumin excretion from spot urine samples predict all-cause and stroke mortality in Africans.

Background: Increased urinary albumin excretion reflects general vascular damage and predicts adverse cardiovascular and renal outcomes. Albuminuria can be determined from easily collected spot urine samples, especially in low-resource settings. However, no prognostic evidence exists for Africans.

Self-reported alcohol intake is a better estimate of 5-year change in blood pressure than biochemical markers in low resource settings: the PURE study.

Background: Despite criticism of self-reported alcohol intake, it is a valuable tool to screen for alcohol abuse as a risk factor for cardiovascular disease. We aimed to compare various self-reported estimates of alcohol use with γ-glutamyltransferase (GGT) and percentage carbohydrate deficient transferrin (%CDT) considering their relationship with blood pressure changes (%BP) over a 5-year period in black South Africans.

Method: We recruited 1994 participants and collected 5-year followed up data (N = 1246).

Indigenous and traditional plants: South African parents' knowledge, perceptions and uses and their children's sensory acceptance.

Background: The dietary shift from indigenous and traditional plants (ITPs) to cash crops and exotic plant food sources increases the risk of malnutrition and other nutrition-related non-communicable diseases, especially in poor rural communities. Farm communities in South Africa have been associated with poor nutritional status and extreme poverty. ITPs have been found to be affordable sources of several micronutrients.

Using an innovative mixed method methodology to investigate the appropriateness of a quantitative instrument in an African context: Antiretroviral treatment and quality of life.

The relationship between quality of life (QoL) and antiretroviral treatment (ART) has mainly been studied using quantitative scales often not appropriate for use in other contexts and without taking peoples' lived experiences into consideration. Sub-Saharan Africa has the highest incidence of HIV and AIDS yet there is paucity in research done on QoL. This research report is intended to give an account of the use of a mixed method convergent parallel design as a novice approach to evaluate an instrument's context specificity, appropriateness and usefulness in another context for which it was designed.

Development and preliminary evaluation of a real-time PCR assay for Halioticida noduliformans in abalone tissues.

Abalone Haliotis midae exhibiting typical clinical signs of tubercle mycosis were discovered in South African culture facilities in 2006, posing a significant threat to the industry. The fungus responsible for the outbreak was identified as a Peronosporomycete, Halioticida noduliformans. Currently, histopathology and gross observation are used to diagnose this disease, but these 2 methods are neither rapid nor sensitive enough to provide accurate and reliable diagnosis.

Differences in health care seeking behaviour between rural and urban communities in South Africa.

Objective: The aim of this study was to explore possible differences in health care seeking behaviour among a rural and urban African population.

Design: A cross sectional design was followed using the infrastructure of the PURE-SA study. Four rural and urban Setswana communities which represented different strata of urbanisation in the North West Province, South Africa, were selected.

A model for the incorporation of the traditional healers into the national health care delivery system of South Africa.

In South Africa the patient uses both the traditional healers and biomedical personnel's services out of need for the best healing therapy to fulfil his/ her health needs. Failure of one to yield the expected results leads to the use of the other. This shunting back and forth prompted the researcher to undertake research and formulated a model demonstrating how the traditional healers can be incorporated into the National Health Care Delivery System of South Africa.
