BACKGROUND It is unclear whether dissemination of automated external defibrillators (AEDs) in public places can improve the rate of survival among patients who have had an out-of-hospital cardiac arrest. METHODS From January 1, 2005, through December 31, 2007, we conducted a prospective, population-based, observational study involving consecutive patients(More)
BACKGROUND The American Heart Association recommends cardiopulmonary resuscitation (CPR) by bystanders with chest compression only for adults who have cardiac arrests, but not for children. We assessed the effect of CPR (conventional with rescue breathing or chest compression only) by bystanders on outcomes after out-of-hospital cardiac arrests in children.(More)
BACKGROUND Previous animal and clinical studies suggest that bystander-initiated cardiac-only resuscitation may be superior to conventional cardiopulmonary resuscitation (CPR) for out-of-hospital cardiac arrests. Our hypothesis was that both cardiac-only bystander resuscitation and conventional bystander CPR would improve outcomes from out-of-hospital(More)
BACKGROUND Immunoglobulin A (IgA) nephropathy is the most common form of glomerulonephritis in the world, and a substantial number of patients develop end-stage renal disease (ESRD). Although there are several prognostic indicators, it remains difficult to predict the renal outcome in individual patients. METHODS A prospective cohort study was conducted(More)
Objective: To examine the association of cigarette smoking with the risk of death from pancreatic cancer in a prospective cohort study. Methods: A total of 110,792 inhabitants, aged 40–79 years (46,465 men and 64,327 women), were enrolled from 1988 to 1990 and followed up for mortality to the end of 1997. At baseline a self-administered questionnaire was(More)
Recent epidemiological studies have shown that high serum levels of insulin-like growth factor-I (IGF-I) are associated with an increased risk of lung, colon, breast and prostate cancer. Since very few studies have addressed the role of serum levels of IGF-I in the development of pancreatic cancer, we conducted a nested case-control study to examine this(More)
We evaluated the associations of such lifestyle factors as alcohol drinking, coffee consumption and medical history with risk of death from pancreatic cancer in a large-scale prospective cohort study [the Japan Collaborative Cohort Study for Evaluation of Cancer Risk (JACC study)] in Japan. Subjects were 110,792 (46,465 men and 64,327 women) inhabitants who(More)
OBJECTIVE To elucidate epidemiologic and clinical manifestations of Japanese patients with giant cell arteritis (GCA), the first nationwide survey for GCA was conducted in 1998 in Japan. METHODS The first questionnaire on GCA for patients treated in 1997 was sent to 10,717 medical departments in Japan. A total of 177 patients were reported. Among the 177(More)
The etiology of pancreatic cancer remains largely unknown. We examined the association of pancreatic cancer deaths with menstrual and reproductive factors in a cohort study involving Japanese women. A total of 63 273 women were followed up for mortality from 1988 to 1999. Information on menstrual and reproductive factors was obtained by a questionnaire(More)
BACKGROUND Psychoses such as hallucinations are a frequent non-motor problem in patients with Parkinson disease (PD) and serious psychosis requires anti-psychotic medications that worsen Parkinsonism. Although psychosis could be associated with patient-related or biological factors such as cognition, age, and severity of PD, it can also be associated with(More)
