The World Health Organization (WHO) is a leading source of trustworthy guidelines in public health, including in emergencies. In addition to standard guidelines produced in preparation for emergency response, WHO has processes and methods for issuing guidelines in the context of urgent public health need, including rapid advice guidelines (production time 2 to 3 months) and health emergency interim guidelines (days to weeks). There are numerous challenges to producing guidelines in response to an emergency in addition to the compressed timeline which necessitates truncating or modifying standard processes...

BACKGROUND/OBJECTIVES: Patients with obstructive sleep apnea (OSA) have an increased the risk of developing atrial fibrillation (AF). However, it remains unclear if patients with OSA carry a higher risk of recurrent AF after successful catheter ablation. This meta-analysis was conducted (1) to evaluate the association between OSA and recurrent AF after catheter ablation, and (2) to assess the effect of continuous positive airway pressure (CPAP) on the risk of recurrent AF in patients with OSA...

OBJECTIVE: Spinal anesthesia is the most frequently performed anesthesia for cesarean section. The American Society of Anesthesiology recommends using pencil-point spinal needles (SNs) over cutting-bevel SNs to reduce postdural puncture headache (PDPH) in their practice guidelines for obstetric anesthesia. However, there is no meta-analysis addressing the impact of the type of SNs on PDPH among women undergoing Cesarean section surgery. METHODS: We conducted a systematic review and meta-analysis including randomized controlled trials comparing the incidence of PDPH of pencil-point SNs with cutting-bevel SNs in patients undergoing Cesarean section with spinal anesthesia...

OBJECTIVE: Several studies have demonstrated that end-stage renal disease (ESRD) patients on dialysis are at higher risk for cerebrovascular events, especially those on hemodialysis. However, the risk of stroke in patients on peritoneal dialysis (PD) compared to those on hemodialysis (HD) remains unclear. We performed this meta-analysis to assess the risks of stroke in ESRD patients on PD compared to HD. METHODS: A systematic review was conducted using MEDLINE, EMBASE, Cochrane databases from inception through January 2018 to identify studies that evaluated the risks of stroke (all types of stroke, ischemic stroke or hemorrhagic stroke) in ESRD patients on different dialysis modalities...

OBJECTIVE: With neoadjuvant therapy increasingly used in advanced rectal cancer, the lymph node ratio (LNR) has been strongly considered to indicate cancer-specific survival in recent years, and a comprehensive evaluation of a large number of studies is deficient. The objective of our study is to pool enough eligible studies to assess the relationship between LNR and prognosis of advanced rectal cancer after neoadjuvant therapy. METHODS: A systematic search was done in the PubMed and EmBase databases (through 1 March 2017) that reported LNR in colorectal cancer after neoadjuvant therapy...

BACKGROUND: Shared decision-making is a central element of evidence-based practice (EBP). Training in EBP has traditionally focused on providers, but there is an increasing interest in developing such educational resources for patients. The aim of this study is to explore the views of patient representatives attending a workshop in EBP. METHODS: We conducted three focus groups with participants attending EBP workshops in 2013, 2014, and 2015. We used the framework method for content analysis...

OBJECTIVE: In 1983, McIntyre and Popper underscored the need for more openness in dealing with errors in medicine. Since then, much has been written on individual medical errors. Furthermore, at the beginning of the 21st century, researchers and medical practitioners increasingly approached individual medical errors through health information technology. Hence, the question arises whether the attention of biomedical researchers shifted from individual medical errors to health information technology...

OBJECTIVE: Nurses play an effective role in diabetic foot care and they should know the best evidence. In this way, implementations according evidence-based clinical practice guidelines have positive effects on nurses' practice and patient outcomes. The objective of this study was quality assessment of diabetic foot ulcer clinical practice guidelines. METHODS: Evidence about nursing care in diabetic foot ulcer in last 5 years was searched and categorized based on nursing diagnosis (ND) and evidence levels and was finally designed as a guideline...

OBJECTIVE: Proper interpretation of survival data of clinical cancer studies may be difficult and pitfalls related to the nature of Kaplan-Meier analyses might end up in mistaken inferences. The purpose of the present work is to raise awareness of those pitfalls and to prevent errors in future studies. STUDY DESIGN AND SETTING: While evaluating a randomized controlled trial, we came across some issues possibly associated with misinterpreting survival data. We thoroughly reviewed the reporting of survival analyses, statistical approaches, baseline characteristics, and choice of primary end point...

Unpredictability arises in numerous real-world implementations especially in medical fields, being one of the principal subjects that expert systems have to deal with. Bayesian networks (BNs) allow constructing expert systems by utilizing likelihood as a measure of uncertainty. A BN is a statistical model that yields a graphical description of the probabilistic associations between a group of pertinent variables. Probabilistic reasoning involves computing the posterior probability of the unobserved variables given the accessible evidence, based on the application of the Bayes theorem...

OBJECTIVE: To assess review articles on pragmatic trials in order to describe how authors define the aim of this type of study, how comprehensive methodological topics are covered, and which topics are most valued by authors. METHODS: Review articles were selected from Medline Database, based on the expression "pragmatic trial" in the titles. Five trained medical students evaluated the articles, based on a list of 15 self-explanatory methodological topics...
