In our previous cross-sectional study, we found that restless legs syndrome (RLS) was associated with erectile dysfunction (ED). Thus, we conducted a prospective study to examine whether RLS was associated with a higher risk of developing ED based on 6 years of follow-up among 10,394 men (mean age = 63.4 years) in the Health Professionals Follow-up Study. RLS was assessed in 2002 using a set of...
Previous studies of predominantly Western populations have reported inconsistent associations between age at menarche and risk of diabetes. We examined this relationship among Chinese women, who generally experience menarche at a later age than Western women. In 2004-2008, China Kadoorie Biobank recruited 302,632 women aged 30-79 years from 10 areas across China, and recorded 5,391 incident cas...
Several studies have analyzed the relationship between coffee consumption and mortality, but the shape of the association remains unclear. We conducted a dose-response meta-analysis of prospective studies to examine the dose-response associations between coffee consumption and mortality from all causes, cardiovascular disease (CVD), and all cancers. Pertinent studies, published between 1966 and...
Mifepristone-misoprostol medical abortion promises to revolutionize reproductive health-care. Several simplifications of the standard three clinic visit regimen may be possible, however. Particularly in developing countries, access to the method can be greatly increased by eliminating the longest clinic visit. Indeed, shortly after mifepristone's introduction in Guadeloupe, a semi-developed Car...
In a prospective study the usefulness of placental grading in detecting IUGR has been evaluated. Those who were echoscopically examined within one week before delivery were taken into the study (n = 137). Changes in placental tissue increased clearly as pregnancy progressed and in 42% (57/137) the placentae reached Grade III. Increasing placental grading is associated with normal maturation of ...
OBJECTIVE To ascertain the annual incidence of diabetes requiring treatment with insulin in children and adolescents aged 0-19 years in Dar es Salaam, Tanzania, during a 10 year period from 1 January 1982 to 31 December 1991. DESIGN Prospective registration at a major urban hospital of all patients with newly diagnosed diabetes who were resident in Dar es Salaam. SETTING Muhimbili Medical C...
BACKGROUND Asymmetric dimethylarginine (ADMA) inhibits the production of nitric oxide, a key regulator of the vascular tone, and may be important in the development of cardiovascular disease (CVD). Our aim was to reliably quantify the association of ADMA and its isomer symmetric dimethylarginine (SDMA) with the risk of CVD outcomes in long-term cohort studies. METHODS AND RESULTS Data were co...
Though much evidence indicates that work stress increases the risk of incident of coronary heart disease (CHD), little is known about the role of work stress in the development of recurrent CHD events. The objective of this study was to review and synthesize the existing epidemiological evidence on whether work stress increases the risk of recurrent CHD events in patients with the first CHD. A ...
Problem Statement: Students may behave differently from each other during the learning process. While some of them struggle to conceive the subject with all respects (the deep studying approach), the others just memorize it without any effort to comprehend (the surface studying approach). Today, students usually learn the strategies on their own regarding how and when to study to be successful....
BACKGROUND Whether light-to-moderate alcohol consumption is protective against stroke, and whether any association differs by stroke type, is controversial. We conducted a meta-analysis to summarize the evidence from prospective studies on alcohol drinking and stroke types. METHODS Studies were identified by searching PubMed to September 1, 2016, and reference lists of retrieved articles. Add...
