Diet and Physical Activity as Determinants of Continuously Measured Glucose Levels in Persons at High Risk of Type 2 Diabetes.

We examined how dietary and physical activity behaviors influence fluctuations in blood glucose levels over a seven-day period in people at high risk for diabetes. Twenty-eight participants underwent a mixed meal tolerance test to assess glucose homeostasis at baseline. Subsequently, they wore an accelerometer to assess movement behaviors, recorded their dietary intakes through a mobile phone application, and wore a flash glucose monitoring device that measured glucose levels every 15 min for seven days. Generalized estimating equation models were used to assess the associations of metabolic and lifestyle risk factors with glycemic variability. Higher BMI, amount of body fat, and selected markers of hyperglycemia and insulin resistance from the meal tolerance test were associated with higher mean glucose levels during the seven days. Moderate- to vigorous-intensity physical activity and polyunsaturated fat intake were independently associated with less variation in glucose levels (CV%). Higher protein and polyunsaturated fatty acid intakes were associated with more time-in-range. In contrast, higher carbohydrate intake was associated with less time-in-range. Our findings suggest that dietary composition (a higher intake of polyunsaturated fat and protein and lower intake of carbohydrates) and moderate-to-vigorous physical activity may reduce fluctuations in glucose levels in persons at high risk of diabetes.

Persistent Anxiety Is Associated with Higher Glycemia Post-Transition to Adult Services in Asian Young Adults with Diabetes.

BACKGROUND: There is little longitudinal information on psychological burden and metabolic outcomes in young adults with diabetes (YAD) in Asia. We aimed to evaluate the association between psychological status and glycemia at baseline and 2 years following transition in a cohort of YAD in Singapore. METHODS: Subjects with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM), aged 17 to 25 years, were recruited from the YAD clinic in Singapore General Hospital. The Hospital Anxiety and Depression and Problem Areas for Diabetes scales were administered at transition (baseline) and at 18 to 24 months. Glycosylated hemoglobin (HbA1c) assessed during routine visits was tracked longitudinally. RESULTS: A total of 98 T1DM (74.8%) and 33 T2DM (25.2%) subjects were recruited between January 2011 and November 2017. At baseline, mean HbA1c was 8.6%±1.7%. Only 26.0% achieved HbA1c of ≤7.5% and 16.8% achieved HbA1c of <7%. At baseline, prevalence of anxiety was 29.8%. At 24 months, 14.1% had persistent anxiety. Those with persistent anxiety had the highest mean HbA1c, particularly at 6 months (persistently anxious vs. persistently non-anxious: 9.9%±1.2% vs. 8.2%±1.9%, P=0.009). At baseline, 9.2% of subjects had depression. This group also had poorer glycemia at baseline (HbA1c of depressed vs non-depressed: 9.6%±2.1% vs. 8.5%±1.6%, P=0.04), which persisted up to 24 months. CONCLUSION: The majority of YAD in Singapore have suboptimal glycemia. Psychological distress is a critical harbinger of poorer metabolic outcomes.

Thyrotoxic periodic paralysis.

This article aims at highlighting the importance of suspecting thyrotoxicosis in cases of recurrent periodic flaccid paralysis; especially in Asian men to facilitate early diagnosis of the former condition. A case report of a 28 year old male patient with recurrent periodic flaccid paralysis has been presented. Hypokalemia secondary to thyrotoxicosis was diagnosed as the cause of the paralysis. The patient was given oral potassium intervention over 24 hours. The patient showed complete recovery after the medical intervention and was discharged after 24 hours with no residual paralysis. Thyrotoxic periodic paralysis (TPP) is a complication of thyrotoxicosis, more common amongst males in Asia. It presents as acute flaccid paralysis in a case of hyperthyroidism with associated hypokalemia. The features of thyrotoxicosis may be subtle or absent. Thus, in cases of recurrent or acute flaccid muscle paralysis, it is important to consider thyrotoxicosis as one of the possible causes, and take measures accordingly.
