BACKGROUND: Evidence for a high degree of heritability of EEG alpha phenotypes has been demonstrated in twin and family studies in a number of populations. However, information on linkage of this phenotype to specific chromosome locations is still limited. This study's aims were to map loci linked to EEG alpha phenotyp…

Although previous studies of today's globalised and competitive research landscape have mentioned the research collaborations of CANZUK countries (i.e., Australia, Canada, New Zealand, and the United Kingdom), none have yet studied them in detail. Further, such studies have used different measures of international rese…

Missing data are frequently encountered across studies in clinical haematology. Failure to handle these missing values in an appropriate manner can complicate the interpretation of a study's findings, as estimates presented may be biased and/or imprecise. In the present work, we first provide an overview of current met…

The statistical analysis of a study's results is critical to its interpretation. Often confused, 2 types of t tests exist for dependent or independent samples. We reviewed randomized controlled trials that included patients undergoing bilateral total hip or knee arthroplasty (dependent samples) that used the t test for…

After nearly three decades of studies evaluating the legal practice of involuntary outpatient commitment, there is yet little consensus about its effectiveness and only limited implementation. Debate continues over how best to assist adults with serious mental illnesses who are unable or unwilling to participate in pre…

(is one of the most aggressive multidrug-resistant bacteria associated with human infections, resulting in high mortality and morbidity. We obtained 1190isolates from different patients with urinary tract infections. The isolates were measured to determine their susceptibility regarding nine specific antibiotics. This…

Epidemiologic research is an exercise in measurement. Observational epidemiologic results usually include a point estimate, a measure of random error such as a frequentist confidence interval, and a qualitative discussion of study limitations. Without randomization of study subjects to exposure groups, inference from s…

OBJECTIVES: Characterization of Treg lymphocytes (CD4+CD25+) in immune response in patients with chronic viral hepatitis C. MATERIALS AND METHODS: Two groups of patients were included: Group A (10 patients with chronic hepatitis C); Group B (10 healthy controls). In both groups, liver markers, liver function tests, ly…

To explore the current and pending strategic agenda of Ontario hospitals (the largest consumers of the provincial healthcare budget), a survey of Ontario acute care hospital CEOs was conducted in January 2004. The survey, with an 82% response rate, identifies 29 strategic priorities under seven key strategic themes con…

Ecosystem services is a concept broadly applicable to describe environmental interrelations with human activities. It serves as a practical instrument for assessing the success of resource management in natural reserves, with the goals of maximising conservation effort and achieving sustainable use. The Gili Matra Mari…

PURPOSE: Large, observational HIV cohorts play an important role in answering questions which are difficult to study in randomized trials; however, they often lack detailed information regarding previous antiretroviral treatment (ART). Knowledge of ART treatment history is important when ascertaining the long-term impa…

This study investigates the role of family and social relationships in cases of attempted suicide in China. Studies, mostly analyzing data from developed countries, have indicated that interpersonal relationships are important predictors of suicidal behaviors. This study's data were derived from a case-control study in…

OBJECTIVE: This exploratory retrospective study assessed demographic and hospital utilization characteristics of patients presenting with methamphetamine use to an urban psychiatric emergency service in New Mexico. METHODS: De-identified data from patients presenting to PES from 2011 to 2015 were extracted from our he…

AIM: The purpose of this retrospective study is to assess implant success rates with various risk factors. MATERIALS AND METHODS: Two hundred patients with a total of 650 implants were selected. Risk factors, such as smoking, antidepressants, bruxism, diabetes, and bone augmentation procedures were considered, and pat…

Newly emerging research suggests that the actual physical location of a study and the geographic context in which a study is implemented influences the types of research methods most appropriate to use in a study as well as the study's research outcomes. This article presents a reflection on the extent to which place i…

OBJECTIVES: Cognitive and sensory difficulties frequently jeopardize informed consent of frail elderly patients This study is the first to test whether preliminary research experience could enhance geriatric patients' capacity to consent. DESIGN/SETTING: A step-wise consent procedure was introduced in a study on fluid…

Gratitude for food is a concept associated with various aspects of healthy and sustainable diet and originates from Buddhism and Shintoism in Japan. Against this background, a scale specifically targeting adults is essential for boosting studies concerning gratitude for food. This study aimed to adapt the Gratitude for…

UNLABELLED: In recent years, there has been a growing awareness of the potential health benefits of the natural environment for human well-being. Given the fast-paced nature of contemporary lifestyles, research into the use of virtual environments as a means to provide various seasonal landscapes has gained increasing…

According to a plethora of research and publications, the volume and amount of pollution are largely attributable to human-made emissions. Even during the recently ended Covid-19 outbreak, there was a notable decrease in global pollution, particularly in Pakistan's heavily populated cities. Due to the current situation…

A study of the natural history of sickle hemoglobinopathies was begun in March 1979. By August 1987, a total of 2824 patients less than 20 years of age were enrolled. There have been 14,670 person-years of follow-up. Seventy-three deaths have occurred. Most of the deaths were in patients with hemoglobin SS. The peak in…
