Measurements ofthelevels ofserumglutamicoxalacetic transaminase (SGO-T)and serum glutamic-pyruvic (SGP-T)have becomeuseful procedures inthediagnosis of somecasesofmyocardial infarction andofliver disorder (forinstance, Shabetai, Iglauer, and Anderson, 1957;Wroblewski andLaDue,1956a andb). Theprocedures described herearetheresult workdonewiththeobject ofestablishing simple economical techniques whichwouldnot require theuseofaspectrophotometer. Hitherto, methods applicable toordinary...
Health & Demographic Surveillance System Profile : The Dikgale and System.
There is no consensus on how best to treat symptom recurrence following previous therapy with Heller myotomy. Our aim was determine the safety and short long-term efficacy of pneumatic dilatation symptomatic in patients previously treated myotomy for idiopathic achalasia.We identified 27 eligible dilatation, as their initial or secondary treatment, from a prospectively acquired database 450 diagnosis achalasia seen between 1995 2010. treatment protocol involved sequential, graded dilatations...
The study was conducted in the Dikgale Health and Demographic Surveillance System (DHDSS) site where we have observed increasing obesity levels, particularly women, despite evidence of high physical activity (PA) a relatively low daily energy intake. This aimed to assess socio-demographic, behavioural biological determinants body mass index (BMI) adult residents permanently residing DHDSS. A cross-sectional which characteristics from 1143 participants (aged 40-60 years) were collected using...
Purpose: We investigated the distribution of objectively measured ambulation levels and association to adiposity in a convenience sample adolescent adult, rural black South Africans. Methods: analyzed 7-d pedometry data, collected over period nine consecutive days, 789 subjects (women, n = 516; men, 273). Adiposity measures included body mass index (BMI) waist circumference (WC). Obesity was defined as BMI ≥ 30 kg·m−2 or WC 102 cm for men 88 women. Results: The average age- BMI-adjusted...
Background Studies on the determinants of carotid intima-media thickness ( CIMT ), a marker sub-clinical atherosclerosis, mostly come from white, Asian, and diasporan black populations. We present data sub-Saharan Africa, which is experiencing rising burden cardiovascular diseases infectious diseases. Methods Results The H3 (Human Hereditary Health) in Africa's AWI-Gen (African-Wits-INDEPTH partnership for Genomic) study cross-sectional conducted adults aged 40 to 60 years Burkina Faso,...
Background: We describe the effect of 2 different accelerometer cut-points on physical activity (PA) patterns in rural and urban black South African women. Methods: Hip-mounted uni-axial accelerometers were worn for 6 to 7 days by (n = 272) 16) participants. Twenty-hour (4 AM 12 AM) PA counts (cts) volumes (min·day −1 ) extracted: sedentary (SED, <100 cts·min ), light (100–759 moderate-1 (MOD1, 760–1951 moderate-2 vigorous (MOD2VG, ≥1952 bouts ≥10 min ≥760 (MOD1VGbt) (MOD2VGbt).

A development of a technique for estimating sugar in blood, cerebrospinal fluid, etc., is described, using 3:5-dinitrosalicylic acid (D.N.S.A.) originally introduced by Sumner (1921). Results can be obtained less than 10 minutes if required. The method well suited to the estimation random blood sugars and handling diabetic clinic requirements hospital laboratories. reagents are cheap, stable, easily prepared. results very close true glucose values fluid. has justified its existence busy...
The Dikgale Demographic Surveillance System (DDSS) site, established in 1995, is one of three rural surveillance sites South Africa. This paper describes detailed mortality patterns a African population the central region Limpopo Province.These data were based on yearly household visits to collect vital events, covering 63, 873 person-years observation over eight years.Crude was 7.5 per 1,000 (females: 6.9, males: 8.1). Under-1 year and under-5 years 15.1 5.8 person-years, respectively. Life...
The authors used an energy expenditure-based approach to determine the non-compliance and compliance with public health physical activity (PA) guidelines in rural, black South Africans.The analysed 7-day objectively measured PA data (NL-2000 pedometer) 508 females 267 males. Compliance was defined for American College of Sports Medicine guideline (ACSM: ≥7.5 <21 kcal/kg/week ≥1.5 kcal/kg/day ≥5 days/week) Institute (IOM: ≥21 ≥3 7 days/week).The age- sex-adjusted prevalence non-compliance,...
The increase in obesity levels South African adolescents is attributed to an energy imbalance such that physical inactivity causally related adiposity. However, some settings occurs spite of high activity levels.To examine objectively measured rural black female and male from periurban relation weight status, specifically the direction strength associations.Seven-day accelerometry-derived pedometry data (step counts expenditure) were collected for 178 (85 females, 93 males; age 13.7 - 18.0...
We investigated the criterion validity of a physical activity index (PAI) derived from socio-demographic variables obtained convenience samples rural African women.We used sample (N = 206) larger dataset which surveyed adult Africans during 1997, and data collected 2003/4 138 women. A three-point PAI (low-, medium- high-subsistence) was constructed four questions related to electricity, cooking methods, water collection availability motorized transport. Criterion measures included adiposity,...
During studies on platelet aggregation using the EEL meter, 8% of individuals tested were found to have platelets which aggregated spontaneously when citrated, platelet-rich plasma was stirred at 37 degrees C. The meter differs from other machines in that it incorporates a vertical stirrer subjects greater mechanical force. When this machine is suggested spontaneous related increased fragility and low levels ADP-inhibitor.
Physical activity (PA) assessment has become increasingly important in establishing the relationship between inactivity and disease. However, there are few examples of validated PA questionnaires used a cross-cultural context. The International Activity Questionnaire (IPAQ) was developed by World Health Organisation/ Centres for Disease Control working group, response to this requirement. aim study measure validity reliability IPAQ South African population. Methods: Test-retest conducted on...
Recent reviews published in the IJBNPA provide more definitive ranges of ambulatory activity usually found four general age groups, and how step data relates to public health guidelines. Of note these was lack from Developing Countries. Apart data, available not presented a format conducive inclusion reviews. Consequently, this paper presents pedometry Africa, such that it is easily for future comparisons. Also addressed need consider adjusting prevalence according standard population structures.
Product design and development processes consist of inter-related activities required to be undertaken in an appropriate sequence reduce the need for iteration increase opportunities concurrency. The structure matrix (DSM) is one several modelling tools used represent dependencies between them. Many algorithms have been developed applied DSM with aim determining a near-optimal terms range objectives. In this paper, enhanced genetic algorithm (GA), referred as divide hybridise (DaHA),...
Objectives. We investigated the sources of variance and reliability in an objective measure physical activity for a 14- hour 4-day monitoring period. Design. A convenience sample rural (N=31) urban (N=30) adult, Northern Sotho-speaking blacks was recruited. Physical assessed 8 consecutive days using uni-axial accelerometer. indices were total counts, average inactivity (
