An approach to anti-AIDS chemotherapy is presented from the point of view of treating seropositive individuals by eliminating the infected dendritic cells that are the in vivo target of HIV-1. Special attention is given to the treatment of Langerhans (dendritic) cells in the skin and epithelia that are infected in vivo…

Beta-blockers modify splanchnic hemodynamics in cirrhotic patients. Nonselective beta-blockers are more effective than selective beta-blockers. Azygos blood flow, as a measure of collateral circulation, including that through varices, is always reduced, but the effects on portal pressure, whether measured directly or b…

OBJECTIVE: To study the effectiveness of hemopoietic growth factors in older patients. DESIGN: Literature review. All articles published in English language between 1987 and 1990 were reviewed. Those reporting studies without age limits as entry criteria and describing the effects of growth factors in individual patie…

To determine whether the dose intensity of chemotherapeutic regimens correlates with the complete remission rate in adult patients with advanced-stage intermediate-grade lymphoma, reports of comparative trials of therapy were reviewed. Reports were identified using MEDLINE, through references from review articles, and…

OBJECTIVE: To assess the cost effectiveness of the current recommendation that persons who have had an adenomatous colon polyp removed have periodic colonoscopic surveillance at fixed and regular intervals. DESIGN: Cost-effectiveness analysis using data from the medical literature in a simulation model to estimate the…

Central nervous system (CNS) toxicity of tricyclic antidepressants (TCAs) is serious, costly, frequent, and difficult to diagnose early in its course. We first reviewed all published, systematic population studies of such CNS toxicity. Of 976 TCA-treated patients, 58 (6%) developed TCA-induced CNS toxicity. The risk of…

AIMS: The optimal short-term antithrombotic strategy following left atrial appendage occlusion (LAAO) remains uncertain, with the need to balance thromboembolic prevention and bleeding risk presenting a critical challenge. Recent evidence suggests that direct oral anticoagulants (DOACs) may provide a favourable safety-…

BACKGROUND AND AIM: The use of acupuncture is becoming increasingly popular in the management of attention-deficit/hyperactivity disorder (ADHD). This systematic review consolidates evidence on acupuncture's efficacy and safety for treating ADHD in children and adolescents. METHODS: Controlled clinical trials assessin…

Anxiety and depression are the most common mental health conditions for children and young people (CYP), yet treatment recommendations vary. Through this umbrella review (meta-analysis of meta-analyses), we aimed to identify the most effective interventions for CYP with anxiety and depression. We searched five electron…

INTRODUCTION AND AIM: Although exercise training is beneficial to patients with polycystic ovary syndrome (PCOS), its impact on cardiometabolic health remains uncertain. Therefore, the objective of the current systematic review with pairwise and network meta-analyses was to investigate the efficacy of different modes o…

CONTEXT: Dyslipidemia is a major risk factor for atherosclerotic cardiovascular disease (ASCVD), and curcumin may help improve lipid metabolism. OBJECTIVE: This umbrella review and updated meta-analysis assessed the effects of curcumin supplementation on lipid profiles. DATA SOURCES: Electronic databases (Medline, Sc…

OBJECTIVE: To compare the effectiveness of various surfactant administration methods. METHODS: We conducted an umbrella review of meta-analyses conducted on randomized controlled trials. The search was conducted in March 2024 in four databases. Two authors screened the results and extracted the data. Review quality wa…

PURPOSE: To determine the effect of levetiracetam (LEV) on partial seizure subtypes (simple partial, complex partial, and secondarily generalized seizures) in patients with refractory epilepsy. METHODS: Pooled results from three placebo-controlled trials were analyzed. RESULTS: A statistically significant reduction i…

This report summarizes efficacy and safety data on the use of flecainide acetate for supraventricular arrhythmias. For this purpose, 60 original articles were identified by a literature search representing data from 1,835 treatment courses. In 18 trials, flecainide was administered intravenously; in 19, orally; and in…

We have previously reported on the design and content of a screening battery involving a "tier" approach for detecting potential immunotoxic compounds in mice (Luster et al., 1988, Fundam. Appl. Toxicol. 10, 2-19). This battery has now been utilized to examine a variety of compounds by the NIEHS Immunotoxicology Labora…

PURPOSE: The optimal sequence of salvage chemotherapy (SC) and autologous bone marrow transplantation (ABMT) for Hodgkin's disease (HD) patients who relapse after primary chemotherapy is unknown. We created a decision analysis model to determine the optimal treatment strategy and the most cost-effective approach. METH…

PURPOSE: To review the recent literature on the efficacy of combined insulin and sulfonylurea therapy in patients with type 2 diabetes. DATA SOURCES: Pertinent articles were obtained through an English-language MEDLINE search from 1979 to 1990 and from the references of these articles. STUDY SELECTION: We reviewed th…

To investigate the possible association between Alzheimer's disease and late maternal age at index birth, we conducted a collaborative re-analysis of existing case-control data sets. Of the 11 studies participating in the EURODEM project, four were included in the analyses regarding maternal age. In all four studies, c…

Considerable epidemiological evidence has accumulated regarding the effect of postmenopausal estrogens on coronary heart disease risk. Five hospital-based case-control studies yielded inconsistent but generally null results; however, these are difficult to interpret due to the problems in selecting appropriate controls…
