Abstract	Abstract Background Medical education requires the implementation of different teaching methods and strategies for future doctors to achieve broad learning objectives. This wide range of methods and strategies includes the use of Information Technologies. For a long time, there was a call for a change in medical education for blending new teaching approaches to lessen medical students’ class time. The COVID-19 pandemic then sped up the transition to the new way of medical education and classroom lectures were quickly moved to a virtual environment. We expect that these changes will continue, and online learning will be one of the main teaching strategies in medical education. Therefore, educational experiences during the COVID-19 pandemic will improve our understanding of online learning and will help to develop blended medical school curricula in the future. For this reason, we aimed to determine students’ overall satisfaction with their online learning experience and to define the main factors affecting students’ satisfaction with their online learning program at Cerrahpaşa Medical Faculty. Methods A cross-sectional survey study was conducted to determine medical students’ overall satisfaction with online learning methods and to identify factors associated with positive and negative satisfaction levels. A questionnaire, consisting of 24 questions to collect demographic characteristics, factors associated with online education experience and overall satisfaction levels was developed and distributed to 1600 medical students. Multivariable linear regression analysis was used to determine the factors associated with positive and negative satisfaction levels. Results Regression analysis showed that being familiar with online teaching techniques (β = 0.19, 95% CI [0.07, 0.30], faculty members’ higher online teaching skill levels (β = 0.42, 95% CI [0.32, 0.51], interactive online teaching approaches (β = 0.54, 95% CI [0.41, 0.67], having a personal workspace (β = 0.43, 95% CI [0.19, 0.67], and a self-reported longer ...

Abstract	Abstract Background During the COVID-19 pandemic, health care systems are under extreme pressure. This study analyzed health care resource use (HCRU) and costs in patients admitted to the hospital for COVID-19 and aimed to estimate the one-year direct medical cost of the disease in Turkey. Methods This retrospective cohort study was conducted between March and July 2020 in a tertiary hospital (n = 1056) in Istanbul. Patient demographics, clinical and treatment characteristics at admission, comorbidities, disease severity, and costs from a payer perspective were evaluated using the microcosting method. The results include LOS, hospital costs, and univariate and generalized linear models to investigate influencing factors. The data were extrapolated to provide a country-level estimate. Results The mean length of stay was 9.1 days (SD 6.9). The mean length of stay was 8.0 days (4.7) for patients hospitalized in wards versus 14.8 days (SD 12.0) for patients hospitalized in the ICU. In univariate analysis, several factors, including O2 therapy (+ 3.7 days), high CRP > 41.8 mg/L (+ 3.8 days), and elevated ferritin (+ 3.5), were found to be associated with a longer LOS (p < 0.05). The direct annual medical cost of COVID-19 was estimated at PPP$ 2.1 billion. The COVID-19 pandemic resulted in a direct medical burden that corresponds to 2.0% of the government health expenditures and 0.8 per thousand of Turkey’s gross domestic product (GDP). Conclusions Estimating the impact of this pandemic in terms of HCRU and costs to the health care system can help design strategies to manage the pandemic.

Abstract	For the past two decades, primary hyperparathyroidism generally has been diagnosed at an asymptomatic stage because of routine biochemical screening. Bone involvement and dental changes are late manifestations of primary hyperparathyroidism, and brown tumors are seen rarely. We present here a case who admitted to the dentistry clinic with left mandibular swelling diagnosed on pathologic examination as giant cell granuloma. Further investigation revealed brown tumors localized to the mandible and was secondary to primary hyperparathyroidism. Primary hyperparathyroidism can present in a variety of ways and should be included in the differential diagnosis of cystic bone lesions, although at present, these lesions are seen rarely.

Abstract	Purpose: This study aimed to investigate the influence of aerobic exercise on the quality of life and leptin and adiponectin levels in patients with type 2 diabetes mellitus. Material and Method: Patients were randomized into two groups: aerobic exercise-training and control group. Parameters were assessed at baseline and end of the twelve-week follow-up for 60 type 2 diabetic patients who completed the program. The 36-item Short Form Health Survey was administered to the patients. Results: The exercise-training group results showed a decrease in adiponectin and leptin levels, a reduction of waist circumference and percentage of body fat (p=0.007, 0.023, 0.012 and 0.048, respectively). The leptin levels in the aerobic exercise group were positively correlated with body mass index (r=0.303, p=0.021) and percentage of body fat (r=0.371, p=0.005); they were negatively correlated with physical problems (r=-0.482; p=0.009) and pain (r=-0.540; p=0.003). Exercise led to statistically significant improvements in the SF-36 physical functioning and mental health subscales (p=0.020 and 0.023, respectively). Discussion: The association of better HbA1c, waist circumference, and percentage of body fat with improved mental and physical scores may be related to a decrease in leptin levels, despite a significant reduction in serum adiponectin levels.

Abstract	Adiponectin, an adipose tissue specific protein encoded by the Adiponectin gene, modulates insulin sensitivity and plays an important role in regulating energy homeostasis. Many studies have shown that single nucleotide polymorphisms (SNPs) in the Adiponectin gene are associated with low plasma Adiponectin levels, insulin resistance and an increased risk of type 2 diabetes mellitus. The aim of the present study was to evaluate the contribution of the Adiponectin gene polymorphisms in genetic background of type 2 diabetes in a Turkish population. In total, 169 unrelated and non-obese diabetic patients and 119 age- and BMI-matched non-diabetic individuals with no family history of diabetes were enrolled in this study. We detected a significant association between type 2 diabetes and two SNPs: SNP â11391G>A, which is located in the promoter region of the Adiponectin gene, and SNP +276G>T, which is found in intron 2 of the gene (P<0.05). The silence SNP G15G (+45T>G) in exon 1 and SNP +349A>G in intron 2 also showed a weak association with type 2 diabetes (P=0.06 and P=0.07, respectively), while SNPs â3971A>G in intron 1 and Y111H, R112C and H241P in exon 3 showed no association (P>0.05). In conclusion, these findings suggest that Adiponectin gene polymorphisms might be effective on susceptibility for type 2 diabetes development which emerged from the interactions between multiple genes, variants and environmental factors.

Abstract	Purpose: To assess the risk of severe hypoglycemia in Turkish patients with type 2 diabetes mellitus (T2DM) starting insulin therapy with premixed insulin analogues alone or in combination with oral antihyperglycemic medications. Material and Method: Data from a subset of Turkish patients who participated in a 1-year, multinational, multicenter, prospective observational study were evaluated. Insulin treatment was initiated using commonly prescribed premixed regimens: insulin lispro mix 25 (25% insulin lispro, 75% insulin lispro protamine suspension) or biphasic insulin aspart 30/70 (30% insulin aspart, 70% insulin aspart protamine suspension) twice daily. Results: Of the 154 patients treated, 61 (39.6%) were male with a mean age of 56 years and a T2DM duration of 8.9 years. Twelve patients (7.8%) experienced ≥1 episode of severe hypoglycemia, but all recovered. The severe hypoglycemic rate was 0.14 episodes/patient-year. The mean glycated hemoglobin decreased by 2.7% (10.4% to 7.8%) and fasting plasma glucose by 115.9 mg/dL (265.3 mg/dL to 157.6 mg/dL) (p<0.0001). Self-monitored blood glucose (2-hour post morning meal) decreased by 163.3 mg/dL (327.0 mg/dL to 216.2 mg/dL; p<0.0001). Self-monitored blood glucose level was low, particularly at the 2-hour post evening meal. Body mass index increased by 1.4 kg/m2, and total daily insulin dose by 4.2 IU. Discussion: In Turkish patients with T2DM, initiation of premixed insulin analogues during routine clinical care significantly improves glycemic control during the first year of treatment, but comes with a risk for severe hypoglycemia. Improvements in physician and patient education within the Turkish population regarding hypoglycemia management may be of benefit. Turk Jem 2013; 17: 83-8

Abstract	Objective: Hospitalization in patients with diabetic foot infection usually increases costs due to required long-term medical treatments and surgical managements. We aimed to investigate the ethiological factors of diabetic foot infections, frequency of osteomyelitis and amputation and the cost of diabetic foot infection treatments.Materials and Method: Patients with DM and diabetic foot infections that was admitted to our Endocrinology clinic between January 2009 and January 2010 was reviewed retrospectively. Demographic properties, phisical examinations, laboratuary tests, treatments, hospitalization time and cost informations of patients were investigated.Results: The mean age of 80 patients with 59 males and 21 females was 62±11 years. All patients were diagnosed as Type 2 DM except four patients (5%) with Type 1 DM. The mean duration of DM in our study group was 15.6 years, the mean hospitalization time was 22.1 days and mean cost per patient was 2573 $.Discussion: Diabetic foot infection is an important complication of DM due to impaired quality of life, loss of work, developement of psychosocial trauma, increased frequency and duration of hospitalization, increased cost of treatment recently. Daily foot care and examination by patients seem an important factor to reduce cost of diabetic foot infections. Turk Jem 2012; 16: 10-3
