    IntroductionThere have been some significant changes regarding healthcare utilization during the COVID-19 pandemic. Majority of the reports about the impact of the COVID-19 pandemic on diabetes care are from the first wave of the pandemic. We aim to evaluate the potential effects of the COVID-19 pandemic on the severity of diabetic ketoacidosis (DKA) and new onset Type 1 diabetes presenting with DKA, and also evaluate children with DKA and acute COVID-19 infection. MethodsThis is a retrospective multi-center study among 997 children and adolescents with type 1 diabetes who were admitted with DKA to 27 pediatric intensive care units in Turkey between the first year of pandemic and pre-pandemic year. ResultsThe percentage of children with new-onset Type 1 diabetes presenting with DKA was higher during the COVID-19 pandemic (p < 0.0001). The incidence of severe DKA was also higher during the COVID-19 pandemic (p < 0.0001) and also higher among children with new onset Type 1 diabetes (p < 0.0001). HbA1c levels, duration of insulin infusion, and length of PICU stay were significantly higher/longer during the pandemic period. Eleven patients tested positive for SARS-CoV-2, eight were positive for new onset Type 1 diabetes, and nine tested positive for severe DKA at admission. DiscussionThe frequency of new onset of Type 1 diabetes and severe cases among children with DKA during the first year of the COVID-19 pandemic. Furthermore, the cause of the increased severe presentation might be related to restrictions related to the pandemic

    The assessment of autofluorescence of the crystalline lens in diabetic patients and healthy controls: can it be used as a screening test?
    (DOVE MEDICAL PRESS LTD, 2018-01-01) Pehlivanoglu, Seren; Acar, Nur; Albayrak, Sinan; Karakaya, Muharrem; Ofluoglu, Ali
    Background: Our purpose was to demonstrate if measuring lens autofluorescence (AF) with a scanning confocal biomicroscope may be used to identify subjects with undiagnosed type II diabetes mellitus (DM), and hence, for it to be used as a marker for the severity of diabetic retinopathy in diabetic patients. Patients and methods: In this cross-sectional, comparative study, lens AF was measured with scanning confocal lens fluorescence biomicroscope in diabetic and healthy groups. Full ophthalmological examination was performed. Blood tests of fasting plasma glucose, and glycosylated hemoglobin were also analyzed. The correlation between lens AF results and blood tests was evaluated in both groups. The cutoff value for the diagnosis of DM using lens AF was investigated. Results: The study included 191 subjects with a mean age of 52.09 +/- 6.75 years. One hundred and seven (56.0\%) subjects were female, and 84 (44.0\%) were male. Eighty-two (42.9\%) patients had type II DM, and 109 (57.1\%) subjects self-reported as normal. The fluorescence ratio (FR) values ranged from 0.09 to 0.46 (0.23 +/- 0.06) in the total group. Mean FR measurements of diabetic subjects were significantly higher (0.27 +/- 0.06) than those without DM (0.20 +/- 0.05), (p=0.001). A statistically significant correlation was found between glycosylated hemoglobin, fasting plasma glucose, and FR. The cutoff point for the FR according to the presence of DM was found to be 0.24 and above (p=0.001), with a sensitivity of 71.95\% and a specificity of 80.73\%. Conclusion: Measuring AF of human lens as an indirect evidence of increased advanced glycaton end products may helpful in detecting impaired glucose metabolism. Our results show highly significant correlation between possibility of DM and FR.

    An overview of polycystic ovary syndrome in aging women
    (GALENOS YAYINCILIK, 2021-01-01) Celik, Ozlem; Kose, Mehmet Faruk
    The manifestations of polycystic ovary syndrome (PCOS), a ubiquitous reproductive disorder, may vary significantly depending on the severity of a number of endocrine and metabolic changes. Although no diagnostic criteria are presently available for PCOS for perimenopausal and menopausal women, the condition can still be suspected in case of a previous diagnosis of the condition, a chronic history of irregular menstrual cycles and hyperandrogenism, and/or polycystic ovarian morphology during the reproductive period. PCOS is associated with long-term health risks, including obesity, diabetes, hypertension, dyslipidemia, metabolic syndrome and cardiovascular risk factors during reproductive age, especially in patients possessing classic phenotypes. The aim of this review was to outline the available data about the impact of PCOS on long-term health risks after reproductive age in patients with PCOS. Previously, it was assumed that women with PCOS would be more prone to develop cardiometabolic diseases after reproductive age but current data suggest that in accordance with the healing in the phenotypic characteristics of PCOS, no deterioration appears to occur in cardiometabolic health in these patients. While there is substantial evidence for a greater prevalence of abnormal subclinical atherosclerotic markers among younger patients with PCOS, data for older women are insufficient. However, there is also support for an increased risk of endometrial cancer in PCOS patients. Extensive prospective cohort studies in which healthy controls as well as patients with defining PCOS phenotypes are observed and monitored from the early reproductive period into the late postmenopausal period should now be performed in order to clarify morbidities and mortality in aging women with PCOS.
