Tranexamic acid might be beneficial for cerebral hemorrhage. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the influence of tranexamic acid on cerebral hemorrhage. PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of tranexamic acid on cerebral hemorrhage were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies...

Patients with chronic kidney disease have an increased cardiovascular morbidity and mortality. It has been recognized that the traditional cardiovascular risk factors could only partially explain the increased cardiovascular morbidity and mortality in patients with chronic kidney disease. Asymmetric dimethylarginine (ADMA) and N-monomethy l-arginine (L-NMMA) are endogenous inhibitors of nitric oxide synthases that attenuate nitric oxide production and enhance reactive oxidative specie generation. Increased plasma ADMA and/or L-NMMA are strong and independent risk factor for chronic kidney disease, and various cardiovascular diseases such as hypertension, coronary artery disease, atherosclerosis, diabetes, and heart failure...

BACKGROUND: The use of surgical drains has been considered mandatory after pancreatic surgery. The role of prophylactic abdominal drainage to reduce postoperative complications after pancreatic surgery is controversial. OBJECTIVES: To assess the benefits and harms of routine abdominal drainage after pancreatic surgery, compare the effects of different types of surgical drains, and evaluate the optimal time for drain removal. SEARCH METHODS: For the last version of this review, we searched CENTRAL (2016, Issue 8), and MEDLINE, Embase, Science Citation Index Expanded, and Chinese Biomedical Literature Database (CBM) to 28 August 2016)...

Patients with stable chronic obstructive pulmonary disease (COPD) frequently exhibit unintentional accentuated peripheral muscle loss and dysfunction. Skeletal muscle mass in these patients is a strong independent predictor of morbidity and mortality. Factors including protein anabolism/catabolism imbalance, hypoxia, physical inactivity, inflammation, and oxidative stress are involved in the initiation and progression of muscle wasting in these patients. Exercise training remains the most powerful intervention for reversing, in part, muscle wasting in COPD...

The present study aimed to investigate the cervical lymph node metastasis of nasopharyngeal carcinoma (NPC) and to establish a novel N staging standard for NPC, based on intensity modulated radiation therapy (IMRT) via a prospective multicenter clinical trial. Between January 2006 and December 2009, a total of 492 patients with NPC without distant metastasis were included in the present study. All patients were treated with IMRT. According to Radiation Therapy Oncology Group division standards, the present study proposed a novel N staging system following the review of magnetic resonance images in comparison with the 7th edition of Union for International Cancer Control/American Joint Committee on Cancer (UICC/AJCC) staging system...

Background: Tobacco smoking is a risk factor for tuberculosis but little is known about the relationship between tobacco smoking and drug-resistant tuberculosis (DR-TB). We undertook a systematic review and meta-analysis to quantitatively assess the association between DR-TB and tobacco smoking. Methods: We searched for relevant studies in the Ovid MEDLINE, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, WANFANG, and WEIPU data-bases from inception to September 1, 2017...

BACKGROUND: Chronic Obstructive Pulmonary Disease (COPD) impacts differently on patients at similar grades, suggesting that factors other than lung function may influence patients' experience of the disease. Recent studies have found associations between genetic variations and patient-reported outcomes (PROs). Identifying these associations might be fundamental to predict the disease progression and develop tailored interventions. This systematic review aimed to identify the genetic variations associated with PROs in COPD...

OBJECTIVE: Few studies have reported predictive factors of outcome after pulmonary endarterectomy (PEA) in chronic thromboembolic pulmonary hypertension. The purpose of this study was to determine factors influencing mortality and predictors of hemodynamic improvement after PEA. METHODS: A total of 383 consecutive patients who underwent PEA between January 2005 and December 2009 were retrospectively reviewed. Among them, 150 were fully reevaluated 7.5±1 months after PEA by NYHA class, 6-minute walk distance (6MWD), percentage of predicted carbon monoxide transfer factor (TLCO) and right heart catheterisation...

: Our objective was to study the preventive effect of lowering blood pressure (BP) by medication and/or lifestyle changes on incident all-cause dementia, Alzheimer's disease and vascular dementia. In this systematic review, we included randomized controlled trials with a BP-lowering intervention. Of the nine included trials, seven assessed the effect of antihypertensive medication and two of a lifestyle or combined intervention. In the intervention arm, 1041 out of 29 029 (3.6%) participants were diagnosed with dementia compared with 1090 out of 28 653 (3...

OBJECTIVES: Anti-N-methyl-D-asparate receptor encephalitis is considered an immune-mediated form of encephalitis with paraneoplastic and nonparaneoplastic forms. Delay in recognition is common and patients typically present to the ICU without a diagnosis or with complications following a delayed diagnosis. The aim of this review is to provide a focused overview for the ICU clinician regarding presentation, diagnosis, and critical care management. DATA SOURCES, STUDY SELECTION, AND DATA EXTRACTION: PubMed database search with manual review of articles involving anti-N-methyl-D-asparate receptor encephalitis...

BACKGROUND: A variety of systemic diseases and conditions can affect the course of periodontitis or have a negative impact on the periodontal attachment apparatus. Gingival recessions are highly prevalent and often associated with hypersensitivity, the development of caries and non-carious cervical lesions on the exposed root surface and impaired esthetics. Occlusal forces can result in injury of teeth and periodontal attachment apparatus. Several developmental or acquired conditions associated with teeth or prostheses may predispose to diseases of the periodontium...

We examine self-experimentation ethics history and practice, related law, use scenarios in universities and industry, and attitudes. We show through analysis of the historical development of medical ethics and regulation, from Hippocrates through Good Clinical Practice that there are no ethical barriers to self-experimentation. When the self-experimenter is a true investigator, there is no other party to be protected from unethical behavior. We discuss the n-of-1 issue in self-experiments, and make suggestions for improving experiment design...

There is a need for studies to assess domestic violence (DV) shelter workers views about brief HIV prevention interventions for shelter residents to improve these workers' provision of HIV prevention interventions to shelter residents. This mixed methods study assessed DV shelter workers' views about the following: (a) the need for and appropriateness of HIV prevention services within DV shelters, (b) the utility (i.e., acceptability, systems support, understanding, and feasibility) of an HIV Risk Assessment and Safety Plan (HIV RASP) for women in DV shelters, and (c) suggested changes to or concerns about using the HIV RASP...

INTRODUCTION: Kidney stone disease (KSD) affects millions of people worldwide and has an increasing incidence. Social media (SoMe) and search engines are both gaining in usage, whilst also being used by patients to research their conditions and aid in managing them. With this in mind, many authors have expressed the belief that SoMe and search engines can be used by patients and healthcare professionals to improve treatment compliance, and to help counselling and management of conditions such as KSD...
