the incidence of NAFLD. FT4 was significantly associated with the risk of NAFLD due to its negatively effect while FT3 was not significantly related to the risk of NAFLD. Taken together, the present meta-analysis provides strong evidence that hypothyroidism may play a vital role in the progression and the development of NAFLD.
  The relationship between serum uric acid (UA) and bone mineral density (BMD) has been proposed by several researchers. However, there has been no consensus regarding the relationships among serum UA, diabetes, and BMD. The aim of this study is to investigate the association between UA, BMD, and at least osteopenia in type 2 diabetes patients.This research was a longitudinal study performed at Xiao-Tang-Shan Hospital in Beijing. Type 2 diabetes diagnosis was consistent with the WHO standard classification. Participants with osteopenia or osteoporosis documented by dual-energy X-ray absorptiometry were defined as having "at least osteopenia." A generalized additive model and multivariable logistic regressions were performed to explore the relationship between serum UA and at least osteopenia. Receiver operating characteristic analysis was conducted. Propensity score matching was used to verify the correctness of the cutoff point.In total, 3476 type 2 diabetes patients free of any osteopenia-related diseases w associated with BMD stratified by sex, age group, and BMI level. Setting the first quartile as the reference, the risk of at least osteopenia in the fourth quartile was significant among all patients (odds ratio [OR] 0.75; 95% confidence interval [CI] 0.57, 0.98) and specifically in females (OR 0.79; 95% CI 0.43, 0.97), patients aged over 50 years (OR 0.79; 95% CI 0.60, 0.97) and patients with a BMI greater than 25 (OR 0.74; 95% CI 0.47, 0.97).  https://www.selleckchem.com/products/mpi-0479605.html  The optimal cutoff point for the serum UA level to distinguish at least osteopenia in diabetic patients was 395 μmol/L.Serum UA concentration is negatively associated with the occurrence of at least osteopenia in Chinese patients with type 2 diabetes.
  Sleep disorders after stroke is one of the most common neuropsychiatric complications and is associated with increased risk of death and poor functional outcomes. Some evidence shows that patients with sleep disorders after stroke benefit from exercise intervention. However, this result is still conflicting. This study aims to explore the effects of exercise on sleep disorders after stroke and to establish safe and effective exercise prescriptions.
 
  The databases including Google Scholar, Pubmed, Embase, and Cochrane library will be searched using pre-specified search strategies. Randomized controlled trials and non-randomized prospective controlled cohort studies regarding exercise for sleep disorders after stroke will be included. The primary outcome is the Pittsburgh Sleep Quality Index (PSQI) scale. The secondary outcomes are adverse events associated with exercise and all deaths. The methodological quality of each study will be evaluated by the physiotherapy evidence database scale. The heterogeneity will be evaluated using the I2 test. If I2 > 50%, random effects models will be used in the analysis; otherwise, fixed effects models will be used to pool the data.
 
  This study will assess the efficacy and safety of exercise for sleep disorders after stroke.
 
  Our findings will be helpful for clinicians to examine the clinical decision-making in the treatment of sleep disorders after stroke using exercise intervention.
 
  Ethical approval is not required because this study is a secondary analysis. The results of this study will be disseminated through journals and academic exchanges.

  The progress of modern society and changes in lifestyle have not only increased the proportion of sub-healthy people, but also caused many people to suffer from sleep disorders and mental anxiety. Long-term lack of high-quality sleep will not only cause psychological problems such as anxiety and fatigue, but also cause physical abnormalities, such as abnormal hormone secretion, weakened immunity, neuroendocrine disorders, and high blood pressure. Therefore, the purpose of this study is to systematically evaluate the effectiveness of aromatherapy in improving sleep quality in people with sleep disorders.
 
  Computer search CNKI, SinoMed, Wanfang, PubMed, Web of science, and EMbase collect randomized controlled trials on aromatherapy to improve sleep quality of people with sleep disorders. The search time limit is to build the database until April 5, 2021. RevMan5.3 software is used for meta-analysis.
 
  This systematic review will provide an assessment of the current state of sleep disorders, aiming to assess the efficacy of aromatherapy for patients with sleep disorders.
 
  This systematic review will provide a credible evidence-based for the clinical treatment of sleep disorders with aromatherapy.

  Metabolic acidosis is observed in 98% of patients with out-of-hospital cardiac arrest (OHCA). The longer the no-flow or low-flow duration, the more severe is the acidosis in these patients. This study explored whether blood pH in early stages of advanced life support (ALS) was an independent predictor of neurological prognosis in patients with OHCA.We retrospectively enrolled patients with OHCA from January 2012 to June 2018 in a single-medical tertiary hospital in Taiwan. Patients with OHCA whose blood gas analyses within 5 minutes after receiving ALS at the emergency department (ED) were enrolled. Patients younger than 20 years old, with cardiac arrest resulting from traumatic or circumstantial causes, with return of spontaneous circulation (ROSC) before ED arrival, lacking record of initial blood gas analysis, and with do-not-resuscitate orders were excluded. The primary outcome of this study was neurological status at hospital discharge.In total, 2034 patients with OHCA were enrolled. The majority were or of post-OHCA neurological outcome. Blood gas analysis on arrival at the ED may provide additional information about the prognosis of patients with OHCA.
