Recently a new prognostic scoring system was developed for paediatric invasive meningococcal disease, based on platelet count and base excess – base excess and platelets score. The main objective of this study was to evaluate the accuracy of...

BACKGROUND Complex humanitarian emergencies are characterised by a break-down of health systems. All-cause mortality increases and non-violent excess deaths (predominantly due to infectious diseases) have been shown to outnumber violent deaths even in exceptionally brutal conflicts. However, affected populations are very heterogeneous and refugees, internally displaced persons (IDPs) and reside...

BACKGROUND Although the association between depression and excess mortality has been well established, it is not clear whether this is greater in major depression than in subthreshold depression. AIMS To compare excess mortality in major depression with that in subthreshold depression. METHOD We searched bibliographic databases and included prospective studies in which both major and subthr...

INTRODUCTION In the recent past, spells of extreme heat associated with appreciable mortality have been documented in developed countries, including North America and Europe. However, far fewer research reports are available from developing countries or specific cities in South Asia. In May 2010, Ahmedabad, India, faced a heat wave where the temperatures reached a high of 46.8 °C with an appare...

BACKGROUND Hip fracture has a high mortality rate, but the actual level of long-term excess mortality and its impact on population-wide mortality remains controversial. The present prospective study investigated short- and long-term excess mortality after hip fractures with adjustment of other risk factors. We calculated the population attributable risk proportion (PARP) to assess the impact of...

BACKGROUND AND OBJECTIVE Adoption studies have been used to disentangle the influence of genes from shared familial environment on various traits and disease risks. However, both the factors leading to adoption and living as an adoptee may bias the studies with regard to the relative influence of genes and environment compared to the general population. The aim was to investigate whether the co...

Excess mortality, rather than reported COVID-19 deaths has been suggested to evaluate the impact of SARS-CoV-2 induced Corona Virus Disease (COVID-19) pandemic on mortality. However, relationship between excess mortality and is perturbed by seasonal phenomena, such as extreme temperatures influenza. Models used estimate often ignore these underlying patterns. We propose a dynamic linear state-s...

OBJECT Atrial fibrillation is associated with excess mortality. This analysis was performed to determine the magnitude of the excess mortality risk. METHODS Life table analysis of a published study of 350 patients undergoing radiofrequency ablation of the atrioventricular node and permanent pacemaker implantation for symptomatic paroxysmal or chronic atrial fibrillation. A substantial proport...

BACKGROUND A significant increase in mortality was observed during cold winters in many temperate regions. However, there is a lack of evidence from tropical and subtropical regions, and the influence of ambient temperatures on seasonal variation of mortality was not well documented. METHODS This study included 213,737 registered deaths from January 2003 to December 2011 in Guangzhou, a subtr...

Mortality was determined in 519 patients with delirium who were seen in psychiatric consultation in two general hospitals. Among 419 patients with simple delirium (DSM-III: 293.00) in-hospital mortality was 26%. As compared to average hospital patients the age adjusted in-hospital excess mortality ratio varied from 6.2 for patients with malignancies to 2.1 for patients with motor system disease...
