Die sogenaamde moderne opvatting van seksualiteit en die implikasies daarvan vir die opvoeding
The sexualisation of modern society and the corresponding massive sex-offensive necessitate fundamental reflection on the so-called modem view of sexuality. In order to reveal some of the fundamental causes for this view of sexuality, characteristics of contemporary Western societies such as the following are referred to: feelings of discontent, uncertainty, futurelessness and hedonism, the influence of mass media and the discreditation and rejection of marriage as an institution. It appears that sexuality has become even more problematic/complicated in culturally diverse societies since the espousal of a so called value pluralism has opened the way for all types of sexual malpractices to be regarded as acceptable. Consequently it is demanded that the sexual education which children receive should consist of factual and neutral information on all sexual (mal-)practices. Christian parents/teachers who want tofulfil their calling however, may not shirk their responsibility of providing emphatic guidance to the children entrusted to them according to the Christian view of life and sexuality
Die huisskool - ân vorm van alternatiewe onderwys
The appearance of the contemporary home school in various Western countries, including the RSA, specifically draws the attention to possible alternatives for formal, institutionalised schooling. In addition to a brief explanation  of the concept home school, this article also attempts to give an indication  of the extent of the home school movement. It appears that the parents need for adequate acknowledgement of their educative responsibility lies at the root of the founding o f home schools. Against this background the article focuses on two particular reasons, the position with regard to Christian-religious convictions in public schools and the unsatisfactory academic standards of these schools. The conclusion arrived at is that home schools fulfil a specific need and should, therefore, be legalised and supported subject to certain conditions
Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.
BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Diabetes in pancreatectomized baboons: A model for pancreatic transplantation studies
This study was designed to assess plasma glucose levels (PLG) and insulin release in totally pancreatectomized baboons when challenged with intravenous glucose administration (IVGTT). Ten animals (Papio ursinus) were used and duodenectomy was intentionally avoided. The PLG at death was 18.0 ± mmol/L, and the mean K-value within 3 days after pancreatectomy was 0.4% ± 0.2%, indicating a significant impairment of glucose disappearance from the blood when compared to the control animals (P < 0.01). Plasma insulin levels before and after stimulation with glucose were below the lowest level of insulin assay sensitivity. We conclude that in the primate, as in the dog, surgical pancreatectomy produced a reliable diabetic model, which is uniformly lethal if left untreated.Articl
Endocrine function after hetero- and ortho-topic segmental pancreatic transplantation in primates
This study assessed the early postoperative pancreatic endocrine function after intraperitoneal segmental hetero- and ortho-topic pancreatic allo-transplantation in hemipancreatectomized, nonimmunesuppressed chacma baboons. Hemipancreatectomized animals remained normoglycaemic but rendered significantly reduced K values and insulin release during IVGTT, findings consistent with major pancreatic resection. Segmental hetero- or ortho-topic pancreatic transplantation did not improve reduced K values and hypoinsulinaemia following hemipancreatectomy although orthotopically sited grafts rendered the best glucose tolerance test curves. Glucagon output during IVGTT remained the same in both transplant models. It is concluded that the postoperative hormonal response was similar in both orthotopic and heterotopic transplant recipients, which indicates that drainage of graft venous effluent into the portal circulation has no advantage over systemic insulin drainage as reflected in this 'diabetic' model.Articl
Effect of cyclosporine and irradiation on experimental pancreatic allografts in the primate
The present study assessed the effectiveness of cyclosporine (CSA) and subtotal marrow irradiation (TL1) alone, and CSA in combination with TL1 in a primate segmental pancreatic allotransplantation model. Continuous administration of CSA 25 mg/kg/day and 50 mg/kg/day resulted in mean graft survival of 21.5 days and 24.5 days, respectively. Administration of fractionated TL1 800 rad (8 Gy) and 1,000 rad (10 Gy) alone resulted in mean graft survival of 13.3 days and 14.5 days, respectively. Of 20 animals that received TL1 1,000 rad (10 Gy) and CSA 25 mg/kg/day orally for 5 days then 10 mg/kg/day intramuscularly indefinitely, 3 had graft survival of > 100 days. Likewise, of a group of 15 animals that received TL1 800 rad (8 Gy) and combined indefinite administration of CSA, 6 had graft survival of > 100 days. Although CSA and TL1 administration alone produced modest pancreatic allograft survival, a combination of IL1 (800 or 1,000 rad) and CSA resulted in highly significant segmental pancreatic allograft survival in the primate.Articl
