Insulin detemir improves glycemic control and reduces hypoglycemia in children with type 1 diabetes: findings from the Turkish cohort of the PREDICTIVE™ observational study

Background: Insulin detemir is a basal insulin analog designed to produce a superior pharmacokinetic profile to basal formulations of human insulin. It has shown consistently improved tolerability in comparison to neutral protamine Hagedorn (NPH) insulin in adult cohorts, but there are relatively few publications involving pediatric cohorts. Methods: The efficacy and safety of insulin detemir in children with type 1 diabetes was assessed using data from the Turkish cohort of PREDICTIVE? (a large, multinational, observational) study. The children investigated were using basal–bolus therapy involving NPH insulin or insulin glargine at baseline but were switched to insulin detemir as part of routine clinical care by their physicians. Results: Twelve weeks of treatment with insulin detemir significantly reduced mean hemoglobin A1c (9.7–8.9%, p < 0.001) and mean fasting glucose [185–162 mg/dL (10.3–9 mmol/L), p < 0.01]. Fasting glucose variability was also lower after treatment with insulin detemir than previously (on either NPH or glargine, p < 0.05). The frequencies of total, major and nocturnal hypoglycemic events were significantly reduced with insulin detemir relative to baseline, with an estimated mean of 6.89 fewer events/patient/yr overall (p < 0.001) and 2.6 fewer nocturnal events/patient/yr (p < 0.01). Weight and insulin dose remained relatively unchanged. Conclusions: Twelve weeks of treatment with insulin detemir improved glycemic control and reduced hypoglycemia in children with type 1 diabetes. This improved tolerability might allow further dose titration and therefore additional improvements in glucose control.     

Sonoelastography of the knee joint

Magnetic resonance imaging (MRI) is generally the preferred method for assessing lesions of the knee cartilage and subchondral bone. There have been a few cartilage imaging studies using real‐time elastosonography (RTE), which has increased in importance and range of use in recent years. The aim of this cadaveric study was to assess the efficacy of a new diagnostic method combining USG and RTE and also to perform intra‐articular examinations together with arthroscopy. A total of 12 fresh unpaired human knees were examined. The laparoscopic ultrasound transducer was deployed using standard anteromedial and anterolateral arthroscopic portals. Iatrogenic defects were examined using mosaicplasty tools in healthy‐looking areas of cartilage, and strain in those areas was measured using RTE. The median strain value of the pathological femoral cartilage region was significantly higher than that of the normal cartilage region (1.23 [0.71–2.24] vs. 0.01 [0.01–0.01], P = 0.002, respectively). Arthroscopic study of cartilage using RTE can be a guide for orthopedic surgeons and use of intra‐articular probes could be universalized. Clin.

Endodontic and orthodontic treatment of fused maxillary central incisors: a case report

Abstract – The purpose of this case report was to describe combined endodontic and orthodontic treatment of a patient who had permanent maxillary central incisors fused with supernumerary teeth. A severe esthetic problem and crowding in the maxillary arch were present clinically. Radiographic examination demonstrated two separate crowns, roots and pulpal canals on each side. The therapy was initiated with endodontic treatment. Six months after the completion of endodontic therapy, mesio‐distal trimming was performed and the defects were restored with anterior resin composites in order to re‐establish the esthetics. Orthodontic treatment was performed for the alignment of the upper arch. Follow‐up at 4 years demonstrated that the teeth were asymptomatic and neither root nor alveolar bone resorption was found. In conclusion, instead of extracting the supernumerary teeth, the anomaly was treated successfully in a conservative way.     

Changes in expressions of ADAM9, 10, and 17 as well as α-secretase activity in renal cell carcinoma

Background

ADAM9, 10, and 17 are a class of disintegrins and metallproteinases with α-secretase activity. There are conflicting results regarding the role(s) of ADAM9, 10, and 17 in carcinogenesis, and only a few studies have examined their levels and cellular localization in renal cell carcinoma (RCC). Studies examining changes in α-secretase activity in RCC compared to enzymatic activity of the uninvolved kidney are lacking.

A novel COVID-19 based truck driver syndemic? Implications for public health,safety, and vital supply chains

U.S. long-haul truck drivers traverse great distances and interact with numerous individuals, rendering them vulnerable to acquiring and transmitting coronavirus disease 2019 (COVID-19). Together, the unique co-occurrence of pronounced health disparities and known COVID-19 infection, morbidity, and mortality risks suggest the possibility of a novel COVID-19 based truck driver syndemic due to advanced driver age and endemic health issues. In turn, COVID-19 sequelae may perpetuate existing health disparities. The co-occurrence of afflictions may also result in compromised safety performance. To curb the likelihood of a COVID-19 based truck driver syndemic, several action stepsare needed. First, key COVID-19 metrics need to be established for this population. Second, relationships between long-haul trucker network attributes and COVID-19 spread need to bedelineated. Third, mutually reinforcing interactions between endemic health disparities and COVID-19 vulnerability need to be elucidated. Finally, grounded in the aforementioned steps, policies and interventions need to be identified and implemented.     

Left Ventricular Thickness Is Increased in Nonhypertensive Turner's Syndrome

Background: Turner's syndrome (TS), the most frequent congenital anomaly in newborn girls, is associated with various cardiovascular abnormalities, predominantly bicuspid aortic valves and aortic coarctation. The causes of the left ventricular hypertrophy (LVH) and ECG findings associated with TS are unknown. We used echocardiography to assess cardiac structure and function in normotensive patients with TS. Method: Thirty-one patients with TS and 30 healthy women were enrolled in this comparative study. Twelve-lead ECG, 24-hour-ambulatory ECG recording, and echocardiography were performed. Results: With 24-hour-ambulatory ECG recording, the mean heart rate (HR) of TS women was higher than non-TS women. With echocardiographic examination, the interventricular septum diastolic thickness, left ventricle posterior wall diastolic thickness (LVPW), the LV mass index (LVMI), and left atrial diameter index (LADi) were significantly higher in TS women compared with controls. Mitral flow A velocity was significantly higher and the ratio of early to late diastolic filling was significantly lower in TS patients. Conclusion: HR, LV wall thicknesses, LVMI and the LADi are significantly increased in normohypertensive TS women. There is also subclinical diastolic dysfunction in these patients.     

Aerobic and Anaerobic Exercise Capacities in Obstructive Sleep Apnea and Associations with Subcutaneous Fat Distributions

Obesity is a strong risk factor for the development and progression of sleep apnea. Responses to exercise by patients with obstructive sleep apnea syndrome (OSAS) are clinically relevant to reducing body weight and cardiovascular risk factors. This study aimed to clarify the aerobic and anaerobic exercise capacities and their possible relationships with other findings in patients with OSAS. Forty patients (30 males, 10 females) and 40 controls (30 males, 10 females) were enrolled in this study. Questionnaires (excessive daytime sleepiness, daytime tiredness, morning headache, waking unrefreshed, and imbalance), overnight polysomnography, indirect laryngoscopy, and aerobic and anaerobic exercise tests were performed. Triceps, subscapular, abdomen, and thigh skinfold thicknesses were measured. Subcutaneous abdominal fat (abdomen skinfold) was significantly higher in OSAS patients than in controls. Maximal anaerobic power and anaerobic capacity were not different significantly between the patients and controls. We found that aerobic capacity was significantly lower in OSAS patients than in controls. Aerobic capacity was negatively correlated with upper-body subcutaneous fat (triceps and subscapular skinfolds) but not correlated with subcutaneous abdominal fat in OSAS patients. In multivariate analyses using all patients, the apnea-hypopnea index remained a significant independent predictor of aerobic capacity after controlling for a variety of potential confounders including body mass index. Our data confirm that central obesity (subcutaneous abdominal fat) is prominent in patients with OSAS. Our results suggest that lower aerobic exercise capacity in patients with OSAS might be due to daily physical activity that is restricted by OSA itself. This study also suggests that the degree of subcutaneous abdominal fat cannot be used for predicting aerobic capacity level. We think that upper-body subcutaneous fat might be suitable for determining the physical fitness of patients with OSAS.
