BACKGROUND: Cesarean section (CS) rates have increased globally, necessitating effective anesthesia management. Single-shot spinal anesthesia has limitations due to its duration and the dose-limiting adverse effects of local anesthetics. OBJECTIVES: To evaluate the effectiveness and safety of intrathecal adjuvants com…

Multiple studies have demonstrated that individual psychotherapy, pharmacotherapy, and the two in combination are all effective treatments for depressed outpatients. However, the implications of these data for clinical practice have been incompletely considered, and the often drawn mistaken conclusion is that they supp…

OBJECTIVE: To review the risks, manifestations, and treatment of cyanide toxicity from nitroprusside therapy. DATA SOURCES: All English case reports identified in Index Medicus (MEDLINE) of cyanide intoxication related to nitroprusside from 1970 to the present were reviewed. In addition, literature regarding the incid…

Available data from comparative trials involving 483 patients were analyzed to determine the rate of infectious morbidity following the use of absorbable staples versus traditional incision and suturing of the vaginal cuff in abdominal hysterectomy. Infections occurred in 24 of 268 (9%) patients who received absorbable…

Studies of risk factors for Alzheimer's disease have been hampered by low statistical power. The data from 11 case-control studies were pooled and re-analysed to evaluate the evidence for the association of Alzheimer's disease with family history of dementia and related disorders, parental age, medical history, and env…

Most versions of the multistage model predict that when persons stop smoking, their excess risk for lung cancer will continue to increase. Discussion of the model usually indicate that the excess risk stabilizes. The data show that the risk declines. Implications for models of carcinogenesis are discussed.

OBJECTIVES: The clinical efficacy of short-acting β-blockers in the management of sepsis remains uncertain. In particular, the comparative effects of two commonly used agents-esmolol and landiolol-have not been clearly established. This network meta-analysis aims to systematically evaluate and compare the effects…

Many clinical trials with 5-fluorouracil and leucovorin have been reported. This combination therapy seems to play an important role in untreated advanced colorectal cancer. In other neoplasms (gastric, head and neck, breast cancer) further studies are required.

The value of adjuvant systemic therapy has been clearly demonstrated in both node-positive and node-negative patients. However, there are many women with favorable prognoses whose breast cancer recurs. It has been possible only recently to identify subsets of patients who are at definite risk for recurrence. Advances b…

This article provides a meta-analytic review of the experimental effects of media violence on viewers' aggression in unstructured social interaction. In the reviewed experiments, children or adolescents were exposed to violent or control presentations and their postexposure behavior was coded for aggression during spon…

Despite publication of the Approved Code of Practice and the Notes for Guidance, implementation of the UK Ionising Radiation Regulations has required local interpretation by nuclear medicine departments. One problem has been the lack of data upon which decisions can be based. In the last five years we and others have m…

BACKGROUND: Previous studies have shown that cognitive behavioral therapy (CBT) is beneficial for enhancing blood sugar monitoring and mental health in diabetic patients, but no studies have compared all CBT formats to determine which one is more effective. This review compared different delivery formats for CBT for di…

OBJECTIVE: To compare the efficacy of different exercise training modalities and doses on pain and function in older adults with osteoarthritis (OA) of the hip and/or knee. DATA SOURCES: We searched Medline, Embase, Web of Science, the Cochrane Library, Scopus, and SPORTDiscus from inception until December 2024. STUD…

To perform a meta-analysis of published reports in an attempt to determine the mean and range of normal ambulatory blood pressure (BP), 23 studies including a total of 3,476 normal subjects were reviewed. Most studies were compatible with a mean 24-h BP in the range of 115-120/70-75 mmHg, a mean day time BP of 120-125/…

The role of oral steroids in the treatment of otitis media with effusion in children is the subject of ongoing debate. To critically evaluate the existing evidence, we performed a formal meta-analysis of six randomized clinical trials (n = 264 children) selected from 14 articles and abstracts. Children receiving steroi…

Although sample size calculation is mandatory in clinical trials, the power of most of the published small size clinical studies, was only about 0.25 instead of 0.80 which is normally required in a standard randomized controlled trial. This phenomenon is probably due to the publication bias. In a cancer clinical study,…

Intuitively, one would assume that the benefit from the use of thrombolytic therapy in reducing mortality in acute myocardial infarction (AMI) is directly related to early recanalization of the thrombosed infarct-related artery. However, a meta-analysis of early clinical trials and the ISIS-II trial results suggests th…

An overview is presented of 23 trials of adjuvant chemotherapy in squamous cell carcinoma of the head and neck. These were reviewed from the point of view of design of the trial, analysis of survival, response rates, meta-analysis, site of failure, toxicity and cost. The minimal increase in survival that could be detec…
