INTRODUCTION: Revascularisation to relieve ischemic pain and prevent limb loss is the cornerstone of critical limb ischemia (CLI) treatment, however not all elderly patients are deemed fit for revascularisation. Patient related outcome measurements are important in these patients. Quality of Life (QoL) results regarding the effect of endovascular, surgical, and conservative treatment on the quality of life (QoL) in the elderly are scarce in current literature. Goal of this study is to explore the outcome of the different treatment modalities in elderly patients suffering from CLI, with a specific focus on QoL...

BACKGROUND: The aim of this RCT was to determine whether elective resection following successful non-operative management of a first episode of acute sigmoid diverticulitis complicated by extraluminal air with or without abscess is superior to observation in terms of recurrence rates. METHODS: This was a single-centre, sequential design RCT. Patients were randomized to elective surgery or observation following non-operative management and colonoscopy. Non-operative management included nil by mouth, intravenous fluids, intravenous antibiotics, CT with intravenous contrast on arrival at hospital, and repeat CT with intravenous and rectal contrast on day 3 in hospital...

Background: As the prevalence of obesity is increasing, the number of patients requiring surgical intervention for obesity-related illness is also rising. The aim of this pilot study was to explore predictors of short-term morbidity and longer-term poor weight loss after bariatric surgery. Methods: This was a single-centre prospective observational cohort pilot study in patients undergoing bariatric surgery. We assessed the accuracy (discrimination and calibration) of two previously validated risk prediction models (the Physiological and Operative Severity Score for the enumeration of Morbidity and Mortality, POSSUM score, and the Obesity Surgical Mortality Risk Score, OS-MS) for postoperative outcome (postoperative morbidity defined using the Post Operative Morbidity Survey)...

BACKGROUND AND OBJECTIVES: Surgical patients frequently require admission in high-dependency units or intensive care units. Resources are scarce and there are no universally accepted admission criteria, so patients' allocation must be optimized. The purpose of this study was to investigate the relationship between postoperative destination of patients submitted to colorectal surgery and the scores ColoRectal Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity (CR-POSSUM) and Surgical Apgar Score (SAS) and, secondarily find cut-offs to aid this allocation...

BACKGROUND: Small bowel obstruction (SBO) is a common indication for emergency laparotomy. There are currently variations in the timing of surgery for patients with SBO and limited evidence on whether delayed surgery affects outcomes. The aim of this study was to evaluate the impact of time to operation on 30-day mortality in patients requiring emergency laparotomy for SBO. METHODS: Data were collected from the National Emergency Laparotomy Audit (NELA) on all patients aged 18 years or older who underwent emergency laparotomy for all forms of SBO between December 2013 and November 2015...

Postoperative hospital stay is longer for frail, older patients, who are more likely to experience prolonged postoperative morbidity and reduced long-term survival. We recorded in-hospital mortality, morbidity and length of stay for 164 patients aged at least 65 years after unscheduled surgery. We evaluated pre-operative frailty with the 7-point Clinical Frailty Scale: 81 patients were 'not vulnerable' (frailty score 1-3) and 83 were 'vulnerable or frail' (frailty score ≧ 4), with mean (SD) ages of 74.7 (7...

Paper presents the phenomenon of thanatosis or death-feigning in selected aphids species. This specific reaction was predominantly analysed on the example of aphid subfamily Lachninae. Individuals of this group were used in experiments, during which a thanatotic response was induced with various results. The response differed from prolonged thanatosis, lasting for several minutes ( Eulachnus rileyi ), through shrinking behaviour (e. g. in Stomaphis graffii ) to non-responsive species such as Cinara ( Sch i zolachnus ) pineti ...

BACKGROUND/AIM: Esophagectomy is still the best therapeutic option for curing resectable esophageal cancer (EC). Radical surgical resection with three-field lymphadenectomy (3FLD) is a potentially curative treatment option. We compared the predictive accuracy of 5 different scores in patients with EC who underwent 3FLD. METHODS: Five years' worth of medical records in a single institution were analyzed (January 2010 to January 2015) from 311 patients who underwent esophagectomy for EC...

Fluid administration has been reported to be associated with an increased risk of acute kidney injury (AKI). We assessed whether, after correction for fluid balance, amount and chloride content of fluids administered have an independent association with AKI. We performed an observational study in patients after major surgery assessing the independent association of AKI with volume, chloride content and fluid balance, after adjustment for Physiological and Operative Severity Score for enUmeration of Mortality and morbidity (POSSUM) score, age, elective versus emergency surgery, and duration of surgery...

Phalangeriform marsupials have often been compared with primates because of similarity in the range of external morphology, ecological niches, and body size between the two radiations. We explore morphological convergence in the masticatory anatomy of strepsirrhine primates and phalangeriforms, through osteological measurements of the mandible and facial skeleton, and through dissection of the masticatory musculature, presenting new data on the arrangement and proportions of jaw adductors in phalangeriforms...

While heterogeneity in social behaviour has been described in many human contexts it is often assumed to be less common in the animal kingdom even though scale-free networks are observed. This homogeneity raises the question of whether the patterns of behaviour necessary to account for scale-free social contact networks, where the degree distribution follows a power law, i.e. a few individuals are very highly connected but most have only a few connections, occur in animals, or whether other mechanisms are needed to produce realistic contact network architectures...

In mammalian pregnancy, the uterus is remodeled to become receptive to embryonic implantation. Since non-invasive placentation in marsupials is likely derived from invasive placentation, and is underpinned by intra-uterine conflict between mother and embryo, species with non-invasive placentation may employ a variety of molecular mechanisms to maintain an intact uterine epithelium and to prevent embryonic invasion. Identifying such modifications to the uterine epithelium of marsupial species with non-invasive placentation is key to understanding how conflict is mediated during pregnancy in different mammalian groups...
