Stroke is the third leading cause of death in North America. Most studies indicate that women are just as likely as men to have an initial stroke but less likely to have a recurrent stroke. Aspirin and ticlopidine are two antiplatelet drugs that reduce the risk of recurrent stroke by 25% to 30%. In some stroke preventi…

Issues in the statistical evaluation for therapeutic efficacy of surgical adjuvant modality therapy on the patients suffering from gastrointestinal cancers were mentioned as follows: 1) When a therapeutic effect is evaluated, it is important that a well-controlled, randomized trial should be requested under the statist…

A review of recent phase II and III studies in advanced gastric carcinoma is presented. Several combination regimens have been developed with high activity in locally advanced and metastatic disease. Among them are etoposide plus adriamycin plus cisplatin (EAP), etoposide plus 5-fluorouracil plus leucovorin (ELF), cont…

Studies on dexamethasone suppression test (DST) and schizophrenia are reviewed and the incidence of nonsuppression in the group of studies on schizophrenic patients is compared to that in the group of studies on normal controls from a previous review article. The incidence of nonsuppression in schizophrenic patients (2…

Monotherapy of hypertension should be the goal of treatment. Even in the elderly hypertensive patient there is a good response to monotherapy with angiotensin-converting enzyme inhibitors as well as to diuretics and calcium channel blockers, despite the low plasma renin activity seen in the elderly. Adverse effects on…

The antibody to the alternative pathway C3 convertase, designated C3 nephritic factor or C3NeF, is an autoantibody that is produced in everyone from the time of birth. The elaboration of C3NeF utilizes germline V-region genes which undergo antigen-driven affinity maturation, resulting in an autoantibody that is produce…

The purpose of this study was to analyze critical care nursing practice research published in leading refereed nursing research journals during the period from 1979 to 1988 to identify knowledge-building methods and research outcomes in critical care nursing. Findings indicate a significant increase in the number of nu…

A multitude of therapeutic regimens have been proposed for the management of peritonitis associated with continuous ambulatory peritoneal dialysis (CAPD). There are, however, few clinical trials that have evaluated the efficacy of these proposed regimens in a prospective, comparative fashion. This retrospective report…

Mitoxantrone, an anthracenedione derivative, has been used for preclinical and clinical studies from the end of the 1970s. Several working mechanisms are suggested such as intercalation and electrostatic interactions with DNA with or without involvement of topoisomerase II, immunosuppressive effects and inhibition of p…

This paper reports an analysis of literature data pertaining to the fraction of particles resulting from regional weapons fallout intercepted by vegetation. A simple model for the interception parameter, alpha, was developed that predicted an increasing interception fraction with increasing distance from detonation sit…

There is a general move towards greater emphasis on point and interval estimates of treatment effect in reporting of clinical trials, so that significance testing plays a lesser role. In this article we examine a number of issues which affect the use and interpretation of conventional estimation methods. Should we acce…

To determine digestible-energy values (DEVs) for unavailable carbohydrate (UC), an analysis was made of published data on 29 human diets with UC from several sources and intakes ranging from 4 to 93 g/d. A distinction was made between apparent DEVs, derived from UC intake and fecal loss, and partial DEVs, derived from…

BACKGROUND: Condylar fractures are common maxillofacial injuries. Although both open and closed treatments are used, the optimal strategy remains debated due to variable functional outcomes and complication rates. PURPOSE: This network meta-analysis compared the functional outcomes and complications of closed treatmen…

BACKGROUND: The optimal percutaneous coronary intervention (PCI) revascularization strategy in patients presenting with multi-vessel (MV) coronary artery disease (CAD) and acute myocardial infarction (MI) has not been systematically addressed. Accordingly, we performed a frequentist network meta-analysis with the aim o…

This systematic review and network meta-analysis compared the efficacy of platelet concentrates with traditional bioactive capping materials on vital pulp treatment (VPT) healing outcomes in permanent human teeth. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) checklist and a…

BACKGROUND: Carotid artery stenosis is a major cause of stroke and is commonly treated with carotid endarterectomy (CEA) or carotid artery stenting (CAS). Trans-carotid artery revascularization (TCAR) has emerged as a newer alternative designed to reduce the risk of procedural stroke. However, comparative evidence on t…

BACKGROUND: Percutaneous left atrial appendage occlusion (LAAO) is a non-pharmacological strategy to prevent stroke and systemic emboli in patients with non-valvular atrial fibrillation (AF). However, data regarding its safety and efficacy profile compared to different oral anti-coagulant regimens remain limited. METH…

AIMS: Obesity, one of the most frequent health risks, represents a global public health problem. The potential impact of L-carnitine, a vital nutrient for energy metabolism, on weight loss is worth considering. However, given the inconclusive results from recent meta-analyses on L-carnitine, we conducted an umbrella me…

INTRODUCTION: Statin-induced myopathy (SIM) is a prevalent adverse event impacting treatment adherence. Despite extensive exploration of single nucleotide polymorphisms (SNPs), conflicting evidence obscures their role in SIM incidence, prompting this network meta-analysis. METHODS: Observational studies meeting eligib…

Observational studies of foods and health are susceptible to bias, particularly from confounding between diet and other lifestyle factors. Common methods for deriving dose-response meta-analysis (DRMA) may contribute to biased or overly certain risk estimates. We used DRMA models to evaluate the empirical evidence for…
