Health futures studies have been carried out in only a few countries, but as interest grows in both national long-term perspective studies and health futures, this pattern is likely to change. Policymakers who decide to launch a national study within the health sector should begin by learning about the alternative purp…

OBJECTIVE: The study's aim was to determine any association between choroid plexus cysts (CPCs) and trisomy 18 in a population of fetuses previously screened by nuchal translucency (NT) thickness measurement. METHODS: During the study period (May 1999 to December 2004), 7,795 fetuses had an NT scan and second-trimeste…

The availability of many complete, annotated proteomes enables the systematic study of the relationships between protein conservation and functionality. We explore this question based solely on the presence or absence of protein homologues (a.k.a. conservation profiles). We study 18 metazoans, from two distinct points…

CONTEXT: There is a long history of research on the familial transmission of schizophrenia and other psychoses. However, few studies have investigated the specificity of the transmission of schizophrenia-psychosis spectrum (SPS) disorders and affective psychoses (APs) or observed high-risk offspring into mid-adulthood.…

The aim is to estimate HBV prevalence and the associated risks among noninjecting cocaine users (NICUs). In 2002-2003, a total of 824 NICUs from Buenos Aires (Argentina) and Montevideo (Uruguay) were interviewed using a structured questionnaire. Serologic tests were carried out for Human Immunodeficiency Virus (HIV), h…

The purpose of this article is to characterize fully employed users of heroin, compare them with their unemployed counterparts, and identify demographic, human, and social capital and drug misuse factors that are differentially associated with full employment. A nested case-control research design was used to identify…

BACKGROUND: Iron deficiency anemia (IDA) and anemia of chronic diseases (ACD) are common in the geriatric population. However, differentiation between IDA and ACD is still problematic. Hepcidin is a key regulator of iron homeostasis: downregulation in the presence of iron deficiency allows enteral iron resorption, whil…

Healthcare quality improvement (QI) studies are systematic analyses of processes and outcomes. As such, they meet one of the federal regulatory criteria defining research. They also meet the second criterion in many instances, generalizability of findings, even if it was not the study's original intent. Therefore, to e…

The goal of this study was to explore two accounts for why sketching during learning from text is helpful: (1) sketching acts like other constructive strategies such as self-explanation because it helps learners to identify relevant information and generate inferences; or (2) that in addition to these general effects,…

Chronic diseases have been the focus of qualitative researchers. However, few studies have explained in depth the methodological options choOsed in the studies and their reasons. This paper presents some reflections on the methodological strategies and procedures used in a multisite, qualitative study whose focus are t…

INTRODUCTION: A near midair collision (NMAC) is defined by the Federal Aviation Administration as an event in which the crew of an aircraft perceives a situation that could lead to a midair collision or an event in which the separation between two aircraft is less than 500 feet (Federal Aviation Administration, 2018).…

BACKGROUND: The tutorial group and its dynamics are a cornerstone of problem-based learning (PBL). The tutor's support varies according to the setting, and it is pertinent to explore group effectiveness in relation to different settings, for example online or campus-based. The PBL groups' effectiveness can partly be as…

Reviewing the literature is an important part of the research process. Systematic steps to follow when evaluating the literature include critiquing the following: title, abstract, problem, purpose, theoretical or conceptual framework or model, implications for nursing, review of literature, hypotheses or research quest…

BACKGROUND: The aetiology of otosclerosis is complex, and probably involves an interaction between genes and environmental factors. Previous studies have revealed genetic linkage with a number of chromosome regions, including position 7q33-36. AIM: To confirm whether linkage exists between otosclerosis and chromosome…

This study's primary objective is to investigate the connection between carbon emissions and global warming by tracking how these emissions causes the climatic changes spread across the environment. Based on theories established from past observations that the effect rates for various factors, a mathematical model has…
