BACKGROUND: Hospitalized older adults with preexisting dementia have increased risk of having delirium, but little is known regarding the effect of delirium superimposed on dementia (DSD) on the outcomes of these patients. Our aim was to investigate the association between DSD and hospital mortality and 12-mo mortality in hospitalized older adults. METHODS AND FINDINGS: This was a prospective cohort study completed in the geriatric ward of a university hospital in São Paulo, Brazil...

INTRODUCTION: The medical diagnoses and frequency of emergency department visits made by children who are later given a diagnosis of maltreatment do not differ much from those of nonabused children. However, the type of medical complaints and frequency of emergency medical services (EMS) use by child homicide victims before their death are not known. We compared EMS use between child homicide victims and children who died from natural causes before their death. METHODS: This was a retrospective case-control study of children 0 to 5 years old who died in Houston, Texas, from 2005 to 2010...

Between 1960 and 1985, Patricia Durbin and colleagues performed studies on the distribution of intravenously and intramuscularly injected Am citrate with dosages ranging from 16 to 32 kBq kg in 30 male and female non-human primates (NHP). Dr. Durbin died unexpectedly in March of 2009, leaving much of the extensive serial blood, bioassay, and autopsy data from these NHP studies unanalyzed. As part of the experimental design, serial blood samples were taken, and urine and feces samples were collected separately for the duration of the study...

OBJECTIVES: Rates of organ donation and transplantation have steadily increased in the United States and Canada over the past decade, largely attributable to a notable increase in donation after circulatory death. However, the number of patients awaiting solid organ transplantation continues to remain much higher than the number of organs transplanted each year. The objective of this study was to determine the potential to increase donation rates further by identifying gaps in the well-established donation after circulatory death process in Ontario...

OBJECTIVE: Childhood exposure to acute, high-dose radiation has consistently been associated with risk of benign and malignant intracranial tumors of the brain and CNS, but data on risks of adulthood exposure to protracted, low-to-moderate doses of radiation are limited. In a large cohort of radiologic technologists, we quantified the association between protracted, low-to-moderate doses of radiation and malignant intracranial tumor mortality. MATERIALS AND METHODS: The study population included 83,655 female and 26,642 male U...

Purpose: A major problem in macular degeneration is the inability to reduce RPE and photoreceptor death. These cells die by necroptosis and apoptosis, respectively, but the upstream activator(s) of these death pathways is unknown. In this study, we use the sodium iodate (NaIO3) model of oxidative stress to test the hypothesis that activation of the Fas receptor contributes to the death of the RPE and photoreceptors. Methods: Sodium iodate was injected in Brown-Norway rats via femoral vein injection...

BACKGROUND: Late arrival in hospital by women experiencing pregnancy complications is an important background factor leading to maternal mortality in Nigeria. The use of effective and timely emergency obstetric care determines whether women survive or die, or become near-miss cases. Healthcare managers have the responsibility to deploy resources for implementing emergency obstetric care. OBJECTIVES: To determine the nature of institutional policies and frameworks for managing obstetric complications and reducing maternal deaths in Nigeria...

Previous observational studies have reported the protective effect of β-blockers on the progression of different types of cancers. In 2011, we published a prospective study, including patients with histologically confirmed malignant melanoma in stage II-IIIA. In total, 25% of them reported previous use of β-blockers that were administered at any time for any other diseases. After a median follow-up of 2.5 years, 34% of the patients in the untreated group showed disease progression. In contrast, only 3% of the patients in the treated group showed progression...

RATIONALE: Pulmonary arterial hypertension (PAH) is characterized in part by increased dead space ventilation, which can be estimated noninvasively at the bedside by measurement of end-tidal CO2 (ETCO2). OBJECTIVES: Prior work has demonstrated that ETCO2 is lower in PAH than control patients, but whether ETCO2 has prognostic value is unknown. We hypothesized that lower measurements of ETCO2 in patients with PAH correlate with worse long-term outcomes. METHODS: Patients with PAH seen in our referral clinic were prospectively recruited for ETCO2 measurement between September 2009 and February 2010...

BACKGROUND: Although place of death has been recognized as a risk factor in caregivers' bereavement adjustment, the estimation of the effect of the place of death needs careful consideration about many potential cofounders. PATIENTS AND METHODS: This study was a nationwide cross-sectional questionnaire survey for bereaved family caregivers of patients with cancer who died in 3 settings: (1) hospice at home; (2) palliative care units (PCUs); and (3) acute hospitals...

AIM: Over 60% of Japanese people hope to die at home; hence, assisting clients in achieving this outcome is an important responsibility of home care providers. This study investigated the effects of nurses' relational coordination with physicians on clients' place of death in home visiting nursing (HVN) agencies. METHOD: Secondary analysis of a public survey conducted in 2015 by local governments in Kurume city, Fukuoka prefecture, Western Japan. Manager nurses from 17 HVN agencies provided data about themselves and their relational coordination with community physicians and 85 deceased clients...

AIMS: Subsequent pregnancies (SSPs) in patients with peripartum cardiomyopathy (PPCM) have a high risk of heart failure relapse. We report on outcome of SSPs in PPCM patients in Germany, Scotland, and South Africa. METHODS AND RESULTS: Among 34 PPCM patients with a SSP, pregnancy ended prematurely in four patients while it was full-term in 30. Overall relapse rate [left ventricular ejection fraction, LVEF <50% or death after at least 6-month follow-up] was 56% with 12% (4/34) mortality...

BACKGROUND: Chronic heart failure (CHF) is the final stage of many heart diseases. To improve outcomes, important risk factors for adverse clinical events in the CHF population need to be identified. The aim of the present study was to delineate the influence of long-term blood pressure (BP) changes on prognosis and mortality in a real-world cohort of CHF patients. METHODS AND RESULTS: This is a retrospective longitudinal analysis. Repeated office BP measurements were scheduled during follow-up visits every 3-6 months...

Late infantile neuronal ceroid lipofuscinosis (LINCL) is a fatal inherited neurodegenerative disease caused by loss of lysosomal protease tripeptidyl peptidase 1 (TPP1). We have investigated the effects of chronic intrathecal (IT) administration using enzyme replacement therapy (ERT) to the brain of an LINCL mouse model, in which locomotor function declines dramatically prior to early death. Median lifespan was significantly extended from 126 days to >259 days when chronic IT treatment was initiated before the onset of disease...

End-of-life decision making is value-laden within the context of culture and bioethics. Also, ethics committee role is difficult to understand on this, thus need for ethnomethodological perspective in an expanding bioethical age. Anthropological approach was utilized to document Yoruba definition and perspective of death, cultural beliefs about end-of-life decision making, factors influencing it and ethics committee role. Interviews were conducted among selected Yoruba resident in Akinyele LGA, Oyo State, Nigeria...

Apoptosis of lymphocytes is associated with immunosuppression and poor prognosis in sepsis. Our previous report showed that histones, nuclear proteins released from damaged or dying cells in sepsis, can mediate lymphocyte apoptosis via mitochondria damage. Grape seed proanthocyanidin extract (GSPE), a natural substance with protective properties against oxidative stress, plays a vital role in cell and mitochondria protection. We thus hypothesized that GSPE may play a protective role in histone-induced lymphocyte apoptosis through its anti-oxidative properties...

BACKGROUND: Worsening renal function during hospitalization for an acute coronary syndrome is strongly predictive of in-hospital and long-term outcome. However, the role of post-discharge worsening renal function has never been investigated in this setting. METHODS: We considered the placebo cohort of the AleCardio trial comparing aleglitazar to standard medical therapy among patients with type 2 diabetes mellitus and a recent acute coronary syndrome. Patients who had died or had been admitted to hospital for heart failure before the 6-month follow-up, as well as patients without complete renal function data were excluded, leaving 2776 patients for the analysis...

BACKGROUND: Soluble ST2 (sST2) is a marker of cardiac mechanical strain hypothesized to adversely impact short-term prognosis after myocardial infarction. We examined the association of sST2 with longer-term outcomes after myocardial infarction in a geographically defined community. METHODS: Olmsted County, Minnesota residents who experienced an incident (first-ever) myocardial infarction between 11/01/2002 and 12/31/2012 were prospectively enrolled; sST2 levels were measured...
