In order to determine which areas of cancer screening are currently receiving greatest emphasis in different parts of the world a Medline search of the literature for the period 2000-2002 was performed, concentrating attention on research into all aspects of efforts for early detection of tumours, with especial attenti…

Acculturation has become a popular variable in research on health disparities among certain ethnic minorities, in the absence of serious reflection about its central concepts and assumptions. Key constructs such as what constitutes a culture, which traits pertain to the ethnic versus "mainstream" culture, and what cult…

Proponents of navigated hip arthroplasty have suggested that it may increase the precision of acetabular component placement. We conducted a systematic review and meta-analysis to evaluate the validity of this theory. We searched, in duplicate, MEDLINE, EMBASE and the Cochrane Central Register of Controlled Trials for…

CONTEXT: Intraoperative consultation is frequently requested by surgeons operating on the gastrointestinal tract, appendix, and peritoneum. In this setting, the pathologist's diagnosis plays a central role in determining whether a resection is needed, and if so, how much to resect and whether it was adequate. There is…

INTRODUCTION: This study clarifies the trends observed in open access (OA) in the biomedical field between 2006 and 2010, and explores the possible explanations for the differences in OA rates revealed in recent surveys. METHODS: The study consists of a main survey and two supplementary surveys. In the main survey, a…

PURPOSE OF REVIEW: Patients with brain tumours show a high symptom burden, and symptoms are difficult to treat and prone to be overlooked. This review of publications dealing with advanced stages of brain tumours tries to assess the knowledge gained in the past 2 years and to develop an outlook for further investigatio…

The human immunodeficiency viruses (HIVs)-acquired immunodeficiency syndrome (AIDS) or HAIDS pandemic originated from lentiviruses of nonhuman primates (thus qualifying as a zoonosis) that moved into humans in Africa. The HAIDS patients eventually die of opportunistic infections, all potentially zoonotic. The HAIDS inf…

OBJECTIVE: To evaluate the safety and efficacy of totally endoscopic repair of atrial septal defect (ASD). METHODS: A review of the literature was conducted. Studies were obtained from the following sources: MEDLINE, EMBASE, Web of Science and CENTRAL Library. Inclusion criteria were: (1) randomised controlled trials,…

Of couples with subfertility, 25% have complete or partial blockage of the fallopian tube. Since the advent of in vitro fertilization (IVF), the role of tubal surgery has diminished. However, this type of surgery continues to be undertaken on selected patients with mild tubal disease, and in those with severe tubal dis…

RATIONALE: It has been suggested that corticosteroid-serotonin interactions are central to the pathophysiology of depression. These interactions have been investigated in healthy and depressed humans, primarily using neuroendocrine techniques. OBJECTIVES: To review the evidence regarding the nature of these interactio…

OBJECTIVE: To review the role of the endogenous cannabinoid system (ECS) in the peripheral and central regulation of food intake, appetite, and energy storage and discuss the potential for the ECS to be an important target for lowering cardiovascular risk. METHODS: Materials used for this article were identified throu…

Several reports have described the use of polymyxins by the intraventricular or intrathecal route for multidrug-resistant Gram-negative meningitis. We reviewed the available clinical evidence regarding intraventricular/intrathecal administration of polymyxins in patients with meningitis, focusing on effectiveness and s…

IMPORTANCE: Randomized studies have shown a decreased risk of intracranial hemorrhage (ICH) with use of novel oral anticoagulants (NOACs). However, it is unclear whether the magnitude of benefit is similar for all NOACs currently available. OBJECTIVE: To perform a systematic review and meta-analysis to quantitatively…

INTRODUCTION: Positioned anatomically between the spinal epidural space and the intramedullary compartment, the spinal subdural space remains the least common area of localized infection in the central nervous system. Infectious processes of the subdural spinal space include subdural spinal empyema, subdural spinal abs…

BACKGROUND: As Director of the US National Library of Medicine (NLM) for 30 years, Dr. Donald A. B. Lindberg was instrumental in bringing biomedical research and healthcare worldwide into the age of genomic and translational medicine through the informatics systems developed by the NLM. Lindberg opened free access and…

BACKGROUND: Studies of the 100 most-cited articles are reported for many subjects. However, none has analyzed the article characteristics associated with high citation frequency. This study aims to (1) graphically depict characteristics of the 100 top-cited articles addressing adult spinal deformity (ASD), (2) diagram…

OBJECTIVE: To describe trends in the use of statistical and epidemiological methods in the medical literature over the past 2 decades. STUDY DESIGN AND SETTING: We obtained all 1,028,786 articles from the PubMed Central Open-Access archive (retrieved May 9, 2015). We focused on 113,450 medical research articles.…

Collecting and analysing all available literature before starting an animal experiment is important and it is indispensable when writing a systematic review (SR) of animal research. Writing such review prevents unnecessary duplication of animal studies and thus unnecessary animal use (Reduction). One of the factors cur…

Physiological responses to postoperative acute pain may impede organ functions (cardiovascular, pulmonary, coagulation, endocrine, gastrointestinal, central nervous system, etc). Pain alleviation improves patient's comfort, but also may minimise perioperative stress response, physiological responses and postoperative o…

BACKGROUND: The last two decades have witnessed a dramatic acceleration in the production of genomic sequence information and publication of biomedical articles. Despite the fact that genome sequence data and publications are two of the most heavily relied-upon sources of information for many biologists, very little ef…
