AIM: To evaluate the reported use of Data Monitoring Committees (DMCs), the frequency of interim analysis, pre-specified stopping rules and early trial termination in neonatal randomised controlled trials (RCTs). METHODS: We reviewed neonatal RCTs published in four high impact general medical journals, specifically looking at safety issues including documented involvement of a DMC, stated interim analysis, stopping rules and early trial termination. We searched all journal issues over an 11-year period (2003-2013) and recorded predefined parameters on each item for RCTs meeting inclusion criteria...

INTRODUCTION: Idiopathic venous thromboembolism (VTE) is associated with the risk of cancer but the risk factors for cancer development in such patients are still uncertain. AIM: To assess risk factors for the development of cancer after a standard course of anticoagulation in patients with first episode of idiopathic VTE. MATERIALS AND METHODS: Subjects were enrolled in the three large prospective multicentre studies: PROLONG (NEJM 2006) PROLONG II (Blood 2010) and DULCIS (Blood 2014)...

PURPOSE: Bibliometric analysis highlights the key topics and studies which have led to the current understanding and treatment of a disease of interest. In this original article we analyze the 100 most cited manuscripts in the field of colorectal cancer (CRC). MATERIALS AND METHODS: The Thomson Reuters Web of Science database with the search terms 'colorectal cancer,' 'colorectal cancer surgery,' 'colon cancer,' 'rectal cancer,' 'colorectal carcinoma,' 'colon carcinoma,' 'rectal carcinoma' and/or 'colonoscopy' was used to identify the manuscripts for the study...

OBJECTIVES: We studied the effects of Hip-deep brain stimulation (DBS) on the expression of the inducible transcription factor c-FOS in the brain of normal rats. MATERIALS AND METHODS: Ten Wistar rats were anesthetized, and nine were implanted with epidural and hippocampal electrodes for brain activity recording; one animal was used as sham. Bipolar stimulating electrodes were implanted in the left hippocampus. Three animals were used as control (implanted but not stimulated), one as sham (not implanted, not stimulated), and six as the study group...

BACKGROUND: Large studies may identify postulated risk factors and interventions with very small effect sizes. We aimed to assess empirically a large number of statistically significant relative risks (RRs) of tiny magnitude and their interpretation by investigators. METHODS: RRs in the range between 0.95 and 1.05 were identified in abstracts of articles of cohort studies; articles published in NEJM, JAMA or Lancet; and Cochrane reviews. For each eligible tiny effect and the respective study, we recorded information on study design, participants, risk factor/intervention, outcome, effect estimates, P-values and interpretation by study investigators...

Each week, half a million readers access the Journal electronically, and our content is now seen online by about four times as many people as those who see the print edition. This mode of information delivery has expanded tremendously since the Journal first went online in 1996.(1) Not so long ago, electronic publishing was viewed as secondary to print publication, basically as a convenient way to deliver the print version of an article. Today, the electronic presentation of scientific articles has become the version of record, with print becoming only one part of the complete publication, which may include video, ...

INTRODUCTION: The objective of this study was to evaluate the management of community acquired pneumonia (CAP) according to conventional clinical criteria applied in the emergency room as compared to a pneumonia prognosis index (PPI) (Fine et al. NEJM 1997). We also analyzed which factors were associated with the need for inpatient treatment in PPI risk category III patients. METHODS: We prospectively enrolled all adults with CAP seen in the emergency room during 1999...

BACKGROUND: Venous thromboembolic disease (VTE) is a major cause of morbidity and mortality in hospitalized patients. Most hospitalized patients with a fatal pulmonary embolism are medical patients who do not have a history of recent surgery [BMJ 302 (1991) 709; J. R. Soc. Med. 82 (1989) 198]. There is evidence suggesting that VTE prophylaxis is indicated in many high risk medical patients [Chest 119 (2001) 132S; NEJM 341 (1999) 793]. However, previous studies have shown that only about one third of high risk medical patients receive VTE prophylaxis [Ann...

The frequency of computed tomography (CT) ordered by emergency department physicians at our facility was noted to sharply increase in early 1998 after a New England Journal of Medicine (NEJM) article recommending routine CT in patients with suspected appendicitis. Numerous studies have proven the accuracy of CT for detecting acute appendicitis; however, the most appropriate use of CT continues to evolve. We sought to evaluate the effect of increased CT use on negative appendectomy rate and perforation rate at our institution and to better delineate in whom CT is most beneficial...

Objective: The search for quality, cost-effective health care programs in the United States is now a major focus in the era of health care reform. New programs need to be evaluated as alternatives are developed in the health care system. The BirthPlace program provides comprehensive perinatal services with certified nurse-midwives and obstetricians working together in an integrated collaborative practice serving a primarily low-income population. Low-risk women are delivered by nurse-midwives in a freestanding birth center (The BirthPlace), which is one component of a larger integrated health network...

This study evaluated the relationship between benzene exposure and low white blood cell (WBC) and red blood cell (RBC) counts. Hematologic screening data collected over a 35 year period at a rubber hydrochloride manufacturing plant were analyzed; an increased risk of leukemia had been demonstrated previously among workers at the plant [Infante et al. (1977).' Lancet 2:76-78; Rinsky et al. (1981): Am J Ind Med 2:217-45 (1987): NEJM 316:1044-1050/. Hematologic screening data were available for 657 of 1,037 (63...

It has been established that subject searches of medical full-text databases obtain higher recall than subject searches in a bibliographic database. In this study we attempted to determine if the same rule might apply when searching for a non-subject parameter such as study design. A simultaneous search of bibliographic and full-text records from the New England Journal of Medicine provided data on the number of items retrieved by each kind of search. Filtering strategies were created for 5 different study types: randomized controlled trials, other clinical trials and prospective studies, cohort studies, longitudinal and follow-up studies, and multicenter studies...
