BACKGROUND: The human dystrobrevin binding protein 1 (DTNBP1) gene has been linked to risk for schizophrenia. Recent studies indicate that several single nucleotide polymorphisms (SNPs) in the DTNBP1 gene may also influence general cognitive ability in both schizophrenic patients and healthy control subjects. We examin…

OBJECTIVE: The authors conducted a meta-analysis of relevant data from primary studies of the genetic epidemiology of major depression. METHOD: The authors searched MEDLINE and the reference lists of previous review articles to identify relevant primary studies. On the basis of a review of family, adoption, and twin s…

Meta-analyses of randomized evidence may include published, unpublished, and updated data in an ongoing estimation process that continuously accommodates more data. Synthesis may be performed either with group data or with meta-analysis of individual patient data (MIPD). Although MIPD with updated data is considered th…

Endoscopic hemostatic therapy for upper gastrointestinal bleeding is gaining widespread acceptance despite often conflicting results of randomized controlled trials. To examine the effect of endoscopic therapy in acute nonvariceal upper gastrointestinal hemorrhage, a meta-analysis was performed using a computerized sea…

Estimates of the risks associated with the use of radiologic contrast agents frequently are based on a subjective review of some of the numerous articles that have been published on the subject. We have chosen instead to synthesize the existing evidence in an objective, quantitative way by statistically combining the d…

A theoretical basis for similar recurrence rates among H2-receptor antagonists exists based on recent concepts of ulcer recurrence, ulcer healing and suppression of nocturnal gastric acidity. In order to compare H2-receptor antagonists in the maintenance therapy of duodenal ulcer, a meta-analysis was carried out using…

CONTEXT: Neuromuscular training (NMT) enhances balance among recreational athletes, but the effectiveness of single- versus multicomponent NMT remains unclear. OBJECTIVE: To compare the effectiveness of single- and multicomponent NMT on balance performance among recreational athletes and explore the influence of age,…

Venous thromboembolism (VTE), including deep vein thrombosis (DVT), and pulmonary embolism (PE), is a common complication in patients with ischemic stroke. Several prophylactic strategies are used to reduce the risk of VTE. However, there is still a lack of consensus on the optimal strategy due to the lack of randomize…

OBJECTIVE: This article aims to assess systematic reviews and/or meta-analyses on calcium-based caries preventive agents, evaluating reported evidence, thereby summarizing a critical appraisal on the subject. MATERIALS AND METHODS: A systematic search was done using PubMed, Cochrane Library, and Web of Science. System…

Insomnia affects up to 50% of hospitalized patients and is strongly associated with longer hospital stays and higher mortality rates, especially among vulnerable individuals. Despite its prevalence, it's often overlooked in clinical practice and research. Our systematic review analyzed and compared pharmacological inte…

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…

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…
