Adipose IR is associated with reduced suppression of FFAs during the OGTT and with an altered adipocytokine profile. The negative relation with insulin secretion deserves further longitudinal investigation in the context of deteriorating glucose tolerance.

Aims In this study, we investigated whether adipose tissue insulin resistance (IR) is affected by the degree of obesity during the fasting and post-prandial state, independent of glucose tolerance among obese children and adolescents. We also tested whether systemic subclinical inflammation is associated with adipose tissue IR. Methods Subjects were recruited to the Yale Pathophysiology of Type 2 Diabetes in Youth Study (NCT01967849). An oral glucose-tolerance test was performed to establish glucose-tolerance status and blood samples were drawn for measurement of free fatty acids (FFAs), to calculate the area under the curve (AUC) of FFA. Adipose tissue insulin resistance was calculated as the product of insulin and FFA concentrations. Results In total, 671 children and adolescents (58.6% females) were included with a mean age of 13.3(2.7) years and BMI Z score of 2.45(0.31). The degree of obesity emerged as an independent predictor of both fasting and post-prandial adipose IR, p < 0.0001. Higher degree of obesity was associated with greater AUC FFA (lower suppression) compared to lower degree of obesity, p = 0.01. Furthermore, higher levels of IL-6 were positively associated with post-prandial adipose tissue IR, p = 0.02. Conclusions The degree of obesity in childhood and adolescence is strongly associated with adipose tissue IR independent of glucose tolerance. This is reflected not only in calculated indices of adipose IR but also in lower suppression of FFAs during the OGTT regardless of glucose tolerance or fasting adipose tissue IR. Furthermore, markers of subclinical inflammation such as IL-6 are associated with adipose tissue IR, independent of other factors.

Objective: A national lockdown was implemented in Israel to slow the viral spread of COVID-19. We assessed the real-time effects of the lockdown on disease expression and lifestyle modifications in pediatric patients with chronic respiratory disorders.Methods: An anonymous electronic questionnaire was distributed during lockdown (March-May 2020) to caregivers of patients with chronic respiratory disorders. The primary outcome was change in disease expression and the secondary outcomes were changes in lifestyle and caregivers' emotional status. Results:The clinical status of one-third of the 445 participating patients (age 0-18 years) reportedly improved, including decreased respiratory symptoms (n = 133, 33%), exacerbation frequency (n = 147, 35%), and use of reliever medications (n = 101, 27.4%). The condition of~10% of the patients worsened. Clinical improvement was noted mostly in young patients <5 years (p = .001), asthmatic patients (p = .033), and patients with multiple underlying respiratory disorders (p = .015). Patients whose condition significantly worsened were more likely to be >5 years (p < .001), had increased screen time, decreased physical activity, and shorter sleep duration compared to their younger counterparts (p = .008, <.001, and .001, respectively). Caregivers' reports (n = 236 [58%]) of their own anxiety levels and perceptions of the patients' elevated health risk were increased, regardless of the children's actual clinical status.Conclusion: COVID-19 lockdown was associated with clinical improvement/stability for most of the surveyed children; however, their caregivers' anxiety level was heightened. An increased sedentary lifestyle was reported mostly in older children.

IntroductionThe COVID-19 pandemic has changed daily life in unexpected ways including strict lockdowns periods that may shape hope. MethodThis study compared hope levels among an online sample of 584 adults in late April 2020 during the COVID-19 lockdown (2020 survey) to 884 adult internet users who participated in the 2019 Hope Barometer survey which was performed six months prior to the COVID-19 pandemic (2019 survey). Both surveys used identical validated hope and depression measures. ResultsDespite high degrees of depression, hope levels slightly but significantly increased in the 2020 survey compared to the 2019 survey. Differences between the 2019 and 2020 surveys appeared across all demographic groups, with no differences related to age, sex, or education. ConclusionsDespite the increased depression, the COVID-19 lockdown was associated with significantly higher hope levels.
