Dementia in South Africa: A Situational Analysis.

There is a need in South Africa to understand the status of available care and support to strengthen responses to dementia. This study provides a situational analysis of the current provisions of health, care and support for older persons, people living with dementia and their families in South Africa. It is a first step towards describing the landscape of needs and services available, and provides an evidence base to inform priority-setting for strengthening responses to dementia in South Africa.

Comprehensive measurement of the prevalence of dementia in low- and middle-income countries: STRiDE methodology and its application in Indonesia and South Africa.

Background: A core element of the Strengthening Responses to Dementia in Developing Countries (STRiDE) programme was to generate novel data on the prevalence, cost and impact of dementia in low- and middle-income countries, to build better health policy. Indonesia and South Africa are two middle-income countries in need of such data.

Aims: To present the STRiDE methodology and generate estimates of dementia prevalence in Indonesia and South Africa.

Transforming dementia research into policy change: A case study of the multi-country STRiDE project.

STRiDE was an ambitious four-year project in seven countries aiming to build capacity around generating and using research to support the development of policies to improve quality of life of people with dementia and their carers. The project's innovative approach combined rigorous academic research and hands-on civil society advocacy. This paper explores the project's unique strategy for policy change and compiles case-studies from several of the STRiDE countries.

Effectiveness of a low-cost UVGI chamber for decontaminating filtering facepiece respirators to extend reuse.

In emergencies like the COVID-19 pandemic, the reuse or reprocessing of filtering facepiece respirators (FFRs) may be required to mitigate exposure risk. Research gap: Only a few studies evaluated decontamination effectiveness against SARS-CoV-2 that are practical for low-resource settings. This study aimed to determine the effectiveness of a relatively inexpensive ultraviolet germicidal irradiation chamber to decontaminate FFRs contaminated with SARS-CoV-2.

A morphological study of the shape of the corpus callosum in normal, schizophrenic and bipolar patients.

Abnormalities in the morphology of the corpus callosum have been found to be involved in cognitive impairments or abnormal behaviour in patients with mental disorders such as schizophrenia and bipolar disorder. The present study investigated morphological shape differences of the corpus callosum in a large cohort of 223 participants between normal, schizophrenic and bipolar patients on MRI scans, CT scans and cadaver samples. Healthy samples were compared to a mental disorder population sample to determine morphological shapes variations associated with schizophrenia and bipolar disorder.

Description of the cross-cultural process adopted in the STRiDE (STrengthening Responses to dementia in DEveloping countries) program: A methodological overview.

Cross-cultural adaptation is an important part of using validated questionnaires across countries and settings. Here we describe the cross-cultural process adopted in the STRiDE (STrengthening Responses to dementia in DEveloping countries) program. We adopted a cross-cultural adaptation process including forward translation, back translations, and cognitive interviews of the STRiDE toolkit.

South African guidelines for receptor radioligand therapy (RLT) with Lu-177-PSMA in prostate cancer.

Background: Prostate cancer is an important cause of morbidity and mortality in South Africa, as it is in the rest of the world. In African men, however, prostate cancer tends to follow a more aggressive course when compared to their European counterparts. This is attributed to a plethora of diverse factors of which an underlying genetic component has been shown to be an important aspect.

The validity of arterial measurements in a South African embalmed body population.

Introduction: Knowledge of the normal arterial diameter at a given anatomical point is the first step toward quantifying the severity of cardiovascular diseases. According to several studies, parameters such as weight, height, age and sex can explain morphometric variations in arterial anatomy that are observed in a population. Before the development of a reference database against which to compare the diameters of arteries in a variety of pathological conditions, the compatibility between embalmed body measurements and computed tomography (CT) measurements must first be established.

Effect of Mixed Basic Military Training on the Physical Fitness of Male and Female Soldiers.

Introduction: Mixed gender basic military training (BMT) is adopted to integrate the female South African soldier into the military. This study aimed to assess gender differences before, during (12 weeks), and after a 20-week mixed BMT course and determine if BMT significantly reduced these differences.

Methods: A total of 186 soldiers (114 male: mean age = 21.

Nutrition education practices of primary school teachers in a resource-constrained community in Gauteng, South Africa.

We investigated the nutrition education (NE) practices of teachers of grade 4‒7 learners in 11 primary schools (85% of total number) of the Bronkhorstspruit district (Gauteng Province) to identify opportunities for improving NE in these schools. A descriptive cross-sectional survey was carried out among a convenient sample of the teachers (N = 73) using a structured nutrition education practice questionnaire. Descriptive data analysis was done.

Learning end-of-life care within a constructivist model: Undergraduate nursing students' experiences.

Background: Although nursing education aims to equip nursing students to provide care to dying patients and their families, nurses often feel ill-prepared to cope with the emotional labour involved in end-of-life care.

Objectives: The aim of the study was to explore and describe nursing students' experiences of end-of-life care through experiential learning within a constructivist educational model.

Method: A qualitative, descriptive design was used.

Novel in silico-designed estradiol analogues are cytotoxic to a multidrug-resistant cell line at nanomolar concentrations.

Purpose: 2-Methoxyestradiol (2ME) is a promising anti-cancer agent that disrupts the integrity and dynamics of the spindle network. In order to overcome the pharmacokinetic constraints of this compound, a panel of sulphamoylated estradiol analogues were in silico-designed by our laboratory. In this study, we analysed the potential of each analogue to induce cell death on a panel of cancer cell lines.

Coupled optical resonance laser locking.

We have demonstrated simultaneous laser frequency stabilization of a UV and IR laser, to coupled transitions of ions in the same spectroscopic sample, by detecting only the absorption of the UV laser. Separate signals for locking the different lasers are obtained by modulating each laser at a different frequency and using lock-in detection of a single photodiode signal. Experimentally, we simultaneously lock a 369 nm and a 935 nm laser to the (2)S(1/2) → (2)(P(1/2) and (2)D(3/2) → (3)D([3/2]1/2) transitions, respectively, of Yb(+) ions generated in a hollow cathode discharge lamp.

Ultrastructural changes of erythrocytes in whole blood after exposure to prospective in silico-designed anticancer agents: a qualitative case study.

Background: Novel, in silico-designed anticancer compounds were synthesized in our laboratory namely, 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10),15-tetraen-17-ol (ESE-15-ol) and 2-ethyl-3-O-sulphamoyl-estra-1,3,5(10)16-tetraene (ESE-16). These compounds were designed to have improved bioavailability when compared to their source compound, 2-methoxyestradiol. This theoretically would be due to their increased binding affinity to carbonic anhydrase II, present in erythrocytes.

Diagnosis and management of Pompe disease.

Pompe disease (PD) is an autosomal-recessively inherited neuromuscular disease that, if not diagnosed and treated early, can be fatal. It can present from early infancy into adulthood. Due to the lack of acid alpha-glucosidase, there is progressive intracellular accumulation of glycogen.

The difference between exercise-induced autonomic and fitness changes measured after 12 and 20 weeks of medium-to-high intensity military training. J Strength Cond Res 30(9): 2453-2459, 2016-The aim of this study was to compare the physical fitness, based on VO2max and exercise-induced cardiac autonomic changes, measured by heart rate variability (HRV) of 12 weeks with 20 weeks of training in the South African National Defence Force.

South African guidelines for the management of Gaucher disease, 2011.

Background: Gaucher disease is an autosomal recessive lysosomal glycosphingolipid storage disorder resulting from a deficiency of lysosomal enzyme acid β-glucosidase (glucocerebrosidase). This partial enzyme deficiency results in accumulation of glycosphingolipid-laden macrophages (Gaucher cells) throughout the liver, spleen, bone marrow, skeleton, lungs and brain (only in types 2 and 3).

Objective: These guidelines aim to provide a standard of care for patients with Gaucher disease in keeping with international standards, but also realistic for South Africa, and to provide a shared-care model for treating physicians and funders regarding care for these patients.

Obsessive-compulsive disorder and trichotillomania: a phenomenological comparison.

Background: Similarities between obsessive-compulsive disorder (OCD) and trichotillomania (TTM) have been widely recognized. Nevertheless, there is evidence of important differences between these two disorders. Some authors have conceptualized the disorders as lying on an OCD spectrum of conditions.

Crystalloid preload versus rapid crystalloid administration after induction of spinal anaesthesia (coload) for elective caesarean section.

Current methods of crystalloid preload administration prior to spinal anaesthesia for elective caesarean section are relatively ineffective in preventing hypotension. This study examined the relevance of the timing of the fluid administered. Fifty women were randomly allocated to receive either 20 ml x kg(-1) of crystalloid solution during 20 minutes prior to induction of spinal anaesthesia (preload), or an equivalent volume by rapid infusion immediately after induction (coload).

Processing of emotional information in seasonal depression across different cognitive measures.

This study examined memory for emotional material, endorsement of emotional adjectives, and negative attributional style (NAS) in seasonal affective disorder (SAD). SAD patients showed elevated NAS and increased endorsement of negative self-referent adjectives, but no memory bias for negative material, when compared with never-depressed controls. Longitudinal analyses revealed that none of these cognitive measures significantly predicted later symptom levels independent of initial symptom levels, in the SAD patients.

Quality of life in anxiety disorders: a comparison of obsessive-compulsive disorder, social anxiety disorder, and panic disorder.

Background: There is growing recognition that the anxiety disorders are disabling disorders associated with substantial morbidity and impaired quality of life (QOL). Nevertheless, there have been few studies comparing QOL across these conditions.

Sampling And Methods: 337 outpatients with obsessive-compulsive disorder (OCD; n = 220), panic disorder (PD; n = 53), or social anxiety disorder (SAD; n = 64) were compared using a number of assessment scales to compare objective and subjective impairment in QOL.

Cognitive aspects of chronic depression.

Previous research on chronic depression has focused on its link with other mood disorders and Axis II personality disorders. However, there are few data examining whether the cognitive perspective applies to this condition. In this cross-sectional study, 42 outpatients with chronic depression were compared with 27 outpatients with nonchronic major depressive disorder and 24 never psychiatrically ill controls on cognitive variables thought to be related to vulnerability to depression (e.
