An incidental case of Wellens＇ syndrome in a community emergency department

INTRODUCTION Wellens'syndrome,also called left anterior descending(LAD)coronary T-wave syndrome,is a characteristic electrocardiographic(ECG)pattern suggestive of coronary artery disease in the preinfarction stage.^([1–3])ECG changes in Wellens'syndrome may signify critical stenosis in the proximal LAD coronary artery.^([1–5])Furthermore。

Community emergency medicine:Benefits and challenges of screening for elder abuse in the emergency department of a developing country

As people live longer and fewer babies are born, the elderly became the fastest and largest growing population of the world, expected to increase further from 86 million in 2005 to 394 million in 2050 worldwide. Older patients represent a large bulk of the population arriving in emergency departments （EDs） all over the world.[1] They use hospitals more frequently than younger patients, have more hospital admissions from the ED and more prolonged hospital stays.[2] Elder abuse is defined as a single, or repeated, act which causes harm or distress to an older person and it can occur within any relationship where there is an expectation of trust from the elder person＇s perspective.[3,4] The ED setting is a particularly important environment being the first point of contact with formal services for the abused elderly population.[5] Careful consideration is demanded when older people attend the ED, with particular attention paid to assessment of subjective and objective data in terms of manifestations and potential indicators of abuse.

The influence of terrain age and altitude on the arthropod communities found on recently deglaciated terrain

Climate warming has been more pronounced in the Arctic than elsewhere, resulting in a recent rapid glacial retreat. Over 85% of the Almajallojekna glacier has disappeared over the last 115 years and it is one of the fastest retreating glaciers in Sweden. In 2011 and 2012, at 18 sites in the vicinity of the remaining glacier network, we sampled arthropods and related the species richness, abundance and proportion of herbivores to altitude （ranging from 824 to 1,524 m.a.s.1.） and the age of the site （ranging from 0 to 〉 115 years）. Temperature was measured at six sites and the average annual air temperature ranged from -3.7℃ to 1.1℃. In total, we recorded 3,705 arthropods from 117 species in nine different taxonomic groups. The most abundant and species-rich group was Coleoptera （1,381 individuals, 41 species） followed by Araneae （1,050 individuals, 15 species） and Macrolepidoptera （732 individuals, 17 species）. Only at lower altitudes did the abundance and species richness of arthropods increase with increasing age of the site. The results were consistent among the studied taxonomic groups and when controlling for sam- piing intensity using two different approaches. The proportion of herbivores decreased with increasing age of the site and with increasing altitude. Clearly, altitude appears more important than the age of the site and, at higher altitudes, abundance, species richness and herbivory are low [Current Zoology 60 （2）： 203-220, 2014].
