While the loss of a parent during childhood may put a person at risk for depression, many studies have failed to confirm the importance of this risk factor. Nevertheless, the relationship between the loss of a parent and depression is of clinical importance. This paper reviews studies of the loss of a parent as a risk…

Oral enteric vaccines are reviewed with particular reference to cholera and typhoid. Enterotoxigenic E. coli, Shigella and Rotavirus vaccines are also considered. Clinical trials of those potentially useful vaccines are surveyed.

Results of numerous independent studies suggest that families of a critically ill hospitalized member have similar needs that they can readily identify as very important. Empirical analysis of results compiled from many studies across patient populations, settings, geographic locations, and over time indicates that fam…

To clarify the role of radiation therapy in the treatment of carcinoma of the pancreas studies with radiotherapy alone, combined interventional or concurrent radio-chemotherapy are reviewed. It is shown that in the case of inoperable tumour radiotherapy alone is inadequate, but by the means of a combination of chemothe…

Knee dislocation is an uncommon orthopedic diagnosis with a high rate of neurovascular complications. The goal of definitive management is to provide a pain free and functional knee through restoration of ligamentous stability and range of motion. Operative management has been suggested to be superior to nonoperative m…

INTRODUCTION: Bias and precision statistics have succeeded regression analysis when measurement techniques are compared. However, when applied to cardiac output measurements, inconsistencies occur in reporting the results of this form of analysis. METHODS: A MEDLINE search was performed, dating from 1986. Studies comp…

The metaanalysis can be either understood as a confirmatory analysis, i.e., imposing a requirement for reproducibility, or it can be rated as a descriptive analysis. To derive confirmatory statements from the statistical metaanalysis of comparative studies, the same requirements prevail as for every individual clinical…

Improving population well-being is increasingly recognized as a global priority, yet evidence on the comparative effectiveness of well-being-focused interventions in adults is fragmented. Here we conduct a preregistered systematic review and network meta-analysis (PROSPERO CRD42023403480) of randomized controlled trial…

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) is a common surgical procedure for the removal of kidney stones. Adequate postoperative analgesia is crucial for enhancing recovery and minimizing complications. Peripheral nerve blocks (PNBs) have emerged as a promising method for managing postoperative pain in PCNL pa…

Hepatic veno-occlusive disease is a serious regimen-related toxicity in patients undergoing hematopoietic stem cell transplantation. We performed a systematic review and meta-analysis of the literature on the effect of anticoagulation in preventing veno-occlusive disease. Several databases and online journals were sear…

To study the effect of transfusion on recurrence of squamous cell carcinoma of the head and neck, we analyzed the records of 143 patients with stage II through IV squamous cell carcinoma of the supraglottic larynx or hypopharynx for whom follow-up to recurrence or 5 years after surgical therapy was available. Variables…

This meta-analysis was performed to determine the efficacy of digoxin, verapamil, and beta-adrenoceptor blockers as prophylaxis against supraventricular arrhythmias (SVAs) after coronary artery bypass graft surgery (CABG). Randomized control trials were included if the electrocardiographic monitoring technique was clea…

Controversy about gastric cancer risk after partial gastrectomy exists, especially in the United States. Therefore, we performed a meta-analysis to determine overall relative risk and weighted mean relative risk for subsets of postgastrectomy patients, define possible high risk patients suitable for surveillance, and a…

Evidence of the potential impact of intravenous thrombolytic therapy on short-term revascularization rates among patients with acute myocardial infarction was sought. Because nonrandomized comparisons with conventional treatment would be subject to various confounders, a meta-analysis of randomized controlled trials wa…

This article reports the results of a meta-analysis of the effectiveness of antiarrhythmic drugs for the suppression of ventricular ectopic depolarizations. We analyzed 97 published articles that referred to a total of 27 drugs and contained data from 2989 patient-treatment trials; our goal was to determine the number…

BACKGROUND: Stroke is a leading cause of long-term disability worldwide, particularly among older adults, and severely compromises functional independence and quality of life. Exercise interventions are well established as effective strategies for promoting motor recovery through improvements in neuroplasticity, fitnes…

BACKGROUND AND OBJECTIVES: Red blood cell transfusions are commonly required in pediatric cranial vault remodeling (CVR); however, they carry risks and potential complications. This study evaluates the evidence on perioperative blood conservation agents assessing their efficacy in optimizing and reducing transfusion re…

OBJECTIVE: Many systematic reviews include only a few studies. It is unclear whether recommendations based on these will be correct in the longer term; hence, this article explores whether meta-analyses give reliable results after only a few studies. STUDY DESIGN AND SETTING: Cumulative meta-analysis of data from 65 m…

Meta-analysis of several large interventional trials in patients with mild to moderate hypertension has shown that coronary events are reduced to a much lesser extent than expected. One of the possible explanations for this are the metabolic side-effects of diuretics and betablockers used in these trials that may count…

Whilst tricyclic antidepressants are efficacious in all depressive syndromes, classical MAO-inhibitors differ substantially from them in their action. They are considered less effective in general and not very effective in endogenous depression, but recommended for the treatment of 'atypical' depression. A new class of…
