The effect of Ramadan fasting on serum osmolality in diabetic patients.

OBJECTIVE: To observe the changes of osmolarity levels due to fasting in Ramadan among type 2 diabetic patients. METHODS: The observational study was conducted from May 16 to June 3, 2019, at the Istanbul Medeniyet University, Istanbul, Turkey, and comprised adult type 2 diabetic patients of either gender visiting the diabetes outpatient clinics during the holy month of Ramadan. Those fasting were placed in Group A, while those not fasting formed Group B. Anthropometric measurements and medications in use were recorded. Blood samples were taken in the morning and before the evening meal. Serum osmolality was calculated using serum levels of sodium, glucose and blood urea nitrogen. Data was analysed using SPSS 16. RESULTS: Of the 52 patients, 27(52%) were in Group A and 25(48%) were in Group B. Overall, there were 22(42%) females and 30(58%) males. The mean morning serum osmolalities of the two groups were not different (p>0.05). The mean evening serum osmolality was not significantly different than the mean morning osmolality in Group A (p=0.22). In Group B, the mean evening serum osmolality was significantly lower than the mean morning osmolality (p=0.004). No significant difference was found between mean morning and evening serum osmolalities of those taking sodium-glucose cotransporter 2 (p>0.05). CONCLUSIONS: There was no biochemical sign of dehydration with Ramadan fasting in type 2 diabetes mellitus patients. Clinical Trial Number: [NCT04392570] Link: https://clinicaltrials.gov/.

The effect of acupressure on sleep quality of older people: A systematic review and meta-analysis of randomized controlled trials.

BACKGROUND AND OBJECTIVE: The effects of acupressure on sleep quality and insomnia symptoms have been studied in various groups of haemodialysis patients, those undergoing surgery, and those living in elderly care homes. The aim of this study is to determine the effect of acupressure on sleep quality in elderly people. METHODS: This study was conducted with a systematic review and meta-analysis. In this study, electronic databases of PubMed, Science Direct, National Thesis centre, Google Scholar, Web of Science, EBSCO were systematically scanned between December 2020 and February 2021 using the keywords "older, elderly, sleep quality, acupressure". The study included 11 articles published in English and Turkish languages without any year limitation. This systematic review and meta-analysis were done by following the PRISMA reporting system. RESULTS: The total sample size of 11 randomized controlled trials included in this systematic review and meta-analysis was 722 (experiment: 363 and control: 359), and the mean duration of acupressure interventions applied was 19.65 ± 11.28 days. The sleep quality of the acupressure group in the elderly was significantly increased compared to the control group (MD: -1.71,%95 CI: -2.31 to -1.11, Z = 5.60, p< 0.00001, I2 = 91%). After the subjects received training for acupressure application and applied acupressure themselves, their sleep quality improved compared to the control group (MD: -0.86, 95% CI: -1.39 to -0.32, p <0.001). CONCLUSIONS: We have utilized meta-analysis to try to reveal statistical significance by pooling small studies with high quality. This meta-analysis provided a potentially effective intervention on the quality of sleep in elderly people.

Analysis of the Prophylactic use of Hydroxychloroquine at the Beginning of the COVID-19 Pandemic Among Physicians.

Objective: Throughout the pandemic, physicians working at the frontlines have embarked on various quests to protect themselves, and many physicians preferred using hydroxychloroquine (HQN) as a prophylactic agent. This study aimed to investigate the reasons leading physicians to use HQN and its effects on them. Materials and Methods: This study is cross-sectional with a target population of physicians working in pandemic hospitals in Istanbul, Turkey. We invited participants from seven hospitals via email between May 14 and June 13, 2020. An online questionnaire, including 57 questions, was sent to physicians. Results: A total of 148 (26%) physicians out of 564 participants had used hydroxychloroquine for prevention. Older physicians and those with a history of exposure to COVID-19 patients without protection used prophylactic HQN more frequently. The use of HQN did not differ statistically in terms of being infected among the exposed physicians (p=0.52). Nineteen (13%) physicians using HQN developed side effects related to the drug. Diarrhea and nausea were the most common. Conclusion: Prophylactic HQN use was more common among physicians older than 40 years and with higher exposure rates to a COVID-19 patient without protection. The physicians working on the front line had the highest rate of infection. HQN was not effective in the prophylaxis of COVID-19 among the exposed physicians.

Perioperative myocardial damage and the incidence of type 2 myocardial infarction in patients with intermediate and high cardiovascular risk.

OBJECTIVE: Perioperative myocardial infarction is a major cause of morbidity and mortality in patients undergoing surgical operations. We aimed to determine the incidence of perioperative myocardial infarction in patients with intermediate- or high-risk Framingham scores. METHODS: One hundred and one patients (62 males, 39 females) over 40 years of age (mean age 72±11 years) median 73 (65-81), min- max (46-96), with Framingham risk scores of 10% or higher, and scheduled for surgical interventions in the orthopedics and urology departments of our hospital were included in the study. Patient demographics, comorbidities, blood pressures, and biochemical data were recorded. Troponin values and electrocardiographic findings were obtained during the immediate preoperative period and on postoperative day 2 and then compared. Perioperative myocardial injury and infarction were diagnosed using the third universal definition of myocardial infarction. RESULTS: In 44 (43%) patients, postoperative troponin values were compared with the preoperative values. In 26 (25%) patients, the changes were consistent with myocardial ischemia or damage. Alterations in troponin values with significant electrocardiogram (ECG) changes were found in 6 patients (6%). CONCLUSION: The risk of postoperative myocardial damage was high in our patients with intermediate or high-risk Framingham scores. This im-plies that close follow-up of these patients with abnormal ECG and troponin values during the pre- and postoperative period is required.

Associations of cereal grains intake with cardiovascular disease and mortality across 21 countries in Prospective Urban and Rural Epidemiology study: prospective cohort study.

OBJECTIVE: To evaluate the association between intakes of refined grains, whole grains, and white rice with cardiovascular disease, total mortality, blood lipids, and blood pressure in the Prospective Urban and Rural Epidemiology (PURE) study. DESIGN: Prospective cohort study. SETTING: PURE study in 21 countries. PARTICIPANTS: 148 858 participants with median follow-up of 9.5 years. EXPOSURES: Country specific validated food frequency questionnaires were used to assess intakes of refined grains, whole grains, and white rice. MAIN OUTCOME MEASURE: Composite of mortality or major cardiovascular events (defined as death from cardiovascular causes, non-fatal myocardial infarction, stroke, or heart failure). Hazard ratios were estimated for associations of grain intakes with mortality, major cardiovascular events, and their composite by using multivariable Cox frailty models with random intercepts to account for clustering by centre. RESULTS: Analyses were based on 137 130 participants after exclusion of those with baseline cardiovascular disease. During follow-up, 9.2% (n=12 668) of these participants had a composite outcome event. The highest category of intake of refined grains (≥350 g/day or about 7 servings/day) was associated with higher risk of total mortality (hazard ratio 1.27, 95% confidence interval 1.11 to 1.46; P for trend=0.004), major cardiovascular disease events (1.33, 1.16 to 1.52; P for trend<0.001), and their composite (1.28, 1.15 to 1.42; P for trend<0.001) compared with the lowest category of intake (<50 g/day). Higher intakes of refined grains were associated with higher systolic blood pressure. No significant associations were found between intakes of whole grains or white rice and health outcomes. CONCLUSION: High intake of refined grains was associated with higher risk of mortality and major cardiovascular disease events. Globally, lower consumption of refined grains should be considered.

Risk of cardiovascular events in patients with metabolic syndrome: Results of a population-based prospective cohort study (PURE Turkey).

OBJECTIVE: Metabolic syndrome (MetS) includes several cardiovascular (CV) risk factors. This study aimed to assess CV risk of MetS, contribution of its components to the risk, and whether MetS provides additional risk beyond its components. METHODS: The Prospective Urban Rural Epidemiology (PURE) Turkey cohort included 3933 individuals aged between 35 and 70 years, with a median follow-up of 8.9 years. MetS was diagnosed as the presence of any of the following criteria: high blood pressure, high fasting plasma glucose, abdominal obesity, low HDL-cholesterol, or high triglycerides. The primary outcome was the composite of fatal CV events, non-fatal myocardial infarction, stroke or heart failure, adjusted for age, sex, smoking, family history of CV diseases, and LDL-cholesterol. RESULTS: The primary outcome was more common in the MetS group [178 (9.2%) vs. 70 (3.5%); corresponding incidence rate of 11.3 vs. 4.2 per 1000 person-years; log-rank p<0.001]. Each component was significantly associated with the primary outcome; however, when the components were sequentially included in the model, abdominal obesity and high triglycerides did not provide additional risk on top of the other three components. The hazard ratio for MetS for the primary outcome was 2.12 (95% confidence interval 1.59-2.81, p<0.001), and the discriminative ability (c-statistics) of the models with MetS and the components was similar. CONCLUSION: MetS increases the risk of CV events more than two-fold. High blood pressure, high fasting plasma glucose, and low HDL-cholesterol are the top three components of MetS for CV risk. MetS and its components have a similar discriminative ability for CV events.

MODY Probability Ratios in Patients Diagnosed with Type 2 Diabetes Mellitus at a Young Age.

OBJECTIVE: Maturity-onset diabetes of the young (MODY) is a non-rare group of monogenic inherited diabetes which is commonly confused with type 1 and type 2 diabetes. Due to high costs of genetic tests that provide a definitive diagnosis, some screening scales are used to identify the high-risk patients. In this study, we aimed to evaluate whether (MODY Probability Calculator [MPC]) which is one of the screening tests will be helpful in identifying our high-risk patients among young patients with type 2 diabetes. METHOD: The patients received the diagnosis of type 2 diabetes aged <35 years were included in the study. The anthropometric characteristics of the patients, the treatments they received at the time of diagnosis, and the current treatments were recorded by retrospectively scanning patient files.The patients with the diagnosis of type 1 diabetes having autoantibodies to the pancreas were excluded from the study. The probability of MODY was calculated using MPC.. RESULTS: The mean age of 72 patients (40% female) was 41.5±7.2 years. Eighteen of the patients (25%) were using insulin at the time of diagnosis. The mean HbA1c was 8.6±2.2% and C-peptide was 2.35±1.52 ng/ml. The mean MODY positive predictive score calculated by MPC for risk of MODY was 11.23 percent. There were 61 patients (84.7%) with a risk of ≤20%, 9 patients (12.5%) with a risk of 20-50%, and 2 patients (2.8%) with ≥50%. In the group with MODY PPV score >20%, the age of onset of diabetes and the body mass index was significantly lower than the others (p<0.05, for both). There was no significant difference between current treatments of both groups. CONCLUSION: It has been reported that MODY risk calculated by MPC may yield different results in different populations. The results of this study showed that 15% of our young-onset diabetes patients had an MPC score above 20 percent. Requesting MODY genetic tests in this 15% of the patient group can be presented as a practical suggestion.
