This is possibly due to increasing obesity, reduced level of activity, sedentary lifestyle, ageing population and industrialisation. Aim: The primary objective of this study was to ascertain the level of activity using a pedometer. The secondary objectives were: (1) to correlate the baseline level of activity with body mass index (BMI), HbA1c and blood pressure (BP), (2) to assess whether 7 000 steps a day influence HbA1c and BP over a three-month period. Method: A total of 110 patients were screened; 95 patients (n = 95) completed the study. At the first visit HbA1c, BMI and BP were measured. At the end of the first month baseline physical activity was recorded using pedometers. Patients were divided into two groups: active (n = 50) and control (n = 45). Patients in the active group were asked to walk a minimum of 7 000 steps/day. The control group were asked to continue their usual activity. These patients were followed up monthly over a period of three months. At each visit BMI, BP and step counts were recorded. HbA1c was measured only at the first and last visit. Result: Activity levels increased significantly in the active group throughout the study. Mean step count for the control group at baseline was 2 923.1 ± 1 136.9, which increased to 3 431.2 ± 1 251.7 by the end of the study. Mean step count for the active group at baseline was 4 609.9 ± 1 702.1, which increased to 7 244.8 ± 1 419.4 by the end of the study. The difference between control and active group was statistically significant (p < 0.001). Systolic and diastolic BP decreased significantly in both groups (p = 0.017) for systolic BP and (p = 0.002) for diastolic BP but no interaction was found between the groups as systolic and diastolic BP decreased at the same rate over time in both groups. HbA1c decreased by 1.04% in the active group; this difference was statistically highly significant (p < 0.001). Conclusion: Increase in activity levels decreases HbA1c by 1.04 percentage point over three months in T2DM (p < 0.001), which is statistically significant.","PeriodicalId":43919,"journal":{"name":"Journal of Endocrinology Metabolism and Diabetes of South Africa","volume":"1 1","pages":"80 - 85"},"PeriodicalIF":0.5,"publicationDate":"2018-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90502702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calf circumference (CC) has been proposed as a surrogate measure of muscle mass in the elderly; however, ethnic/sex specific cut-off values remain to be established. Objective: A study was undertaken to investigate the relationship between CC and appendicular skeletal muscle mass (ASM), and the ASM index (ASMI), as well as to determine whether CC could be used to diagnose sarcopenia. Methods: This was a cross-sectional study of 247 older black women living from Tlokwe, South Africa. ASM was measured using dual-energy X-ray absorptiometry, and the ASMI was calculated. Receiver operator characteristics curves and maximum Youden index were applied to identify a CC cut-off point for sarcopenia according to low gait speed (< 0.8 m/s), low hand-grip strength (< 16 kg) and low ASMI using a South African cut-off point for sarcopenia (ASMI < 4.94 kg/m2). Results: A strong positive correlation between CC and ASMI (r = 0.84, p < 0.001) was observed. The CC to predict low hand-grip strength was 34.3 cm and 37.8 cm for low gait speed. A CC of 29.9 cm was indicative of sarcopenia. The area under the curve for all outcomes was > 0.60. Conclusion: A CC of 30 cm is proposed as a simple and inexpensive way to predict, screen or diagnose sarcopenia in black women in low-resource health settings. An accessible, inexpensive screening or diagnostic tool could facilitate timely interventions and prevention.","PeriodicalId":43919,"journal":{"name":"Journal of Endocrinology Metabolism and Diabetes of South Africa","volume":"329 1","pages":"86 - 90"},"PeriodicalIF":0.5,"publicationDate":"2018-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83070702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: A cohort design was used. Participants were 157 pregnant women with diabetes, and the setting was Mbuya Nehanda and Chitungwiza Maternity Hospitals, Harare, Zimbabwe. Results: Main outcome measures were maternal and perinatal outcomes. Mean adherence to anti-diabetic therapy was 66.7%. Perinatal outcomes observed were hypertensive disorders (34.5%), Caesarean delivery (45.9%), maternal diabetic ketoacidosis (5.1%), maternal hypoglycaemia (15.9%), and candidiasis (19.7%).

The authors hypothesise that such a mechanism also contributes to the development of diabetic nephropathy in those patients. Aim: The aim of this study was to evaluate the association of DNA fragmentation damage with diabetic nephropathy in type II diabetes mellitus, so as to use it as a future novel predictive marker. Patients and methods: The study population included 100 patients with diabetic nephropathy, 100 diabetic patients without nephropathy and 100 healthy volunteers as controls. Lipid profile, fasting and post-prandial blood glucose, micro-albuminuria (micro-alb) and glycosylated haemoglobin (HbA1c) were assessed in patients and controls. The technique of capillary electrophoresis was used to detect DNA damage. Results: The frequency of DNA damage in peripheral blood mononuclear cells was 71% in diabetic nephropathy compared with 45% in non-nephropathy patients (p < 0.001). None of healthy controls showed such a finding. Oxidative DNA fragmentation in the diabetic nephropathy group was 3.06 times that in the non-nephropathy group. Neither poor glycaemic control nor dyslipidaemia contributed to DNA damage in diabetic patients. Multivariate analysis showed that positive oxidative DNA damage test (OR1.58, p = 0.02) and the duration of ongoing DM (OR 1.48, p = 0.004) were the only independent factors contributing to the occurrence of diabetic nephropathy. Conclusion: Type II diabetic patients have more liability to oxidative DNA damage in general with a significantly higher frequency in diabetic nephropathy. DNA fragmentation analysis can be used as a predictive diagnostic biomarker for diabetic nephropathy.","PeriodicalId":43919,"journal":{"name":"Journal of Endocrinology Metabolism and Diabetes of South Africa","volume":"89 1","pages":"32 - 35"},"PeriodicalIF":0.5,"publicationDate":"2018-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80976299","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Evidence-based nutrition principles and recommendations are summarised by the Society for Endocrinology, Metabolism and Diabetes in South Africa (SEMDSA) into guidelines for the management of T2DM. This study aimed to determine the adherence of patients with T2DM with the SEMDSA lifestyle guidelines. Methods: A cross-sectional study was conducted in a private practice (n = 50), during which an interviewer-assisted questionnaire related to socio-demographics, diet and lifestyle was completed with each participant. Participants were also weighed and measured. Results: 88% of participants were overweight (22%) or obese (66%). Diets consumed were generally high in total energy (TE) (median: 13 272 kJ), low in carbohydrates (CHO) (56% of participants consumed < 45% of CHO from TE), high in saturated fat (92% consumed ≥ 7% from TE) and high in sodium (74% of participants consumed ≥ 2 300 mg sodium daily). Exercise was not commonplace; 84% of participants did not meet the guideline for aerobic exercise and 92% did not meet the guideline for resistance training.

The second part of the series compares the PK/PD profiles of longer-acting basal analogue insulins, insulin degludec (IDeg) and insulin glargine U300 (Gla-300). The patient populations for glucose clamp studies with these analogue insulins differ, and therefore direct comparison of the data is not always possible.
