Substantial underreporting of anastomotic leakage after anterior resection for rectal cancer in the Swedish Colorectal Cancer Registry

Background: The causes and effects of anastomotic leakage after anterior resection are difficult to study in small samples and have thus been evaluated using large population-based national registries. To assess the accuracy of such research, registries should be validated continuously. Material and methods: Patients who underwent anterior resection for rectal cancer during 2007–2013 in 15 differe

A review of invasive and non-invasive sensory feedback in upper limb prostheses

Introduction: The constant challenge to restore sensory feedback in prosthetic hands has provided several research solutions, but virtually none has reached clinical fruition. A prosthetic hand with sensory feedback that closely imitates an intact hand and provides a natural feeling may induce the prosthetic hand to be included in the body image and also reinforces the control of the prosthesis. A

Epidemiology and causes of death in a Swedish cohort of patients with autoimmune hepatitis

Background: Epidemiological studies of autoimmune hepatitis (AIH) show varying figures on prevalence and incidence, and data on the long-term prognosis are scarce. Objective To investigate the epidemiology, long-term prognosis and causes of death in a Swedish AIH cohort. Material and methods: Data collected from 634 AIH patients were matched to the Cause of Death Registry, and survival analyses we

Effect of increased water intake on plasma copeptin in healthy adults

Purpose: Inter-individual variation in median plasma copeptin is associated with incident type 2 diabetes mellitus, progression of chronic kidney disease, and cardiovascular events. In this study, we examined whether 24-h urine osmolality was associated with plasma copeptin and whether increasing daily water intake could impact circulating plasma copeptin. Methods: This trial was a prospective stu

Depletion of ATP and glucose in advanced human atherosclerotic plaques

Objective: Severe hypoxia develops close to the necrotic core of advanced human atherosclerotic plaques, but the energy metabolic consequences of this hypoxia are not known. In animal models, plaque hypoxia is also associated with depletion of glucose and ATP. ATP depletion may impair healing of plaques and promote necrotic core expansion. To investigate if ATP depletion is present in human plaque

Integration of Interfaces and Stabilization System in the Design of a Drift Tube Linac

Making an accurate Radio Frequency, RF, design of any accelerating structure is fundamental to ensure that electromagnetic and beam dynamics requirements will be achieved. This is essential for the most complicated accelerating structureslike the Drift Tube Linac, DTL; in this case a meticulous design facilitates the RF commissioning too. In this paper the influence of the interfaces and of the fi

Health-related quality of life data from a phase 3, international, randomized, open-label, multicenter study in patients with previously treated mantle cell lymphoma treated with ibrutinib versus temsirolimus

Mantle cell lymphoma (MCL) is a rare, aggressive, incurable B-cell malignancy. Ibrutinib has been shown to be highly active for patients with relapsed/refractory (R/R) MCL. The RAY trial (MCL3001) was a phase 3, randomized, open-label, multicenter study that compared ibrutinib with temsirolimus in patients with R/R MCL. Active disease is frequently associated with impaired functional status and re

Software Engineers' Information Seeking Behavior in Change Impact Analysis -- An Interview Study

Software engineers working in large projects must navigate complex information landscapes. Change Impact Analysis (CIA) is a task that relies on engineers' successful information seeking in databases storing, e.g., source code, requirements, design descriptions, and test case specifications. Several previous approaches to support information seeking are task-specific, thus understanding engineers'

Individual Defects in InAs/InGaAsSb/GaSb Nanowire Tunnel Field-Effect Transistors Operating below 60 mV/decade

Tunneling field-effect transistors (TunnelFET), a leading steep-slope transistor candidate, is still plagued by defect response, and there is a large discrepancy between measured and simulated device performance. In this work, highly scaled InAs/InxGa1−xAsySb1‑y/GaSb vertical nanowire TunnelFET with ability to operate well below 60 mV/decade at technically relevant currents are fabricated and char

On the accuracy of trade and GDP statistics in Africa : Errors of commission and omission

African trade statistics suffer from errors of commission and omission. A quarter-century ago, Alexander Yeats (1990) compared receipts of importers and exporters and concluded that the data could not be used to determine the magnitude, direction, or composition of trade. The only fact to be safely deduced from the evidence was that the statistics were plagued by widespread smuggling and/or underr

GDP Revisions and Updating Statistical Systems in Sub-Saharan Africa : Reports from the Statistical Offices in Nigeria, Liberia and Zimbabwe

The quality of economic statistics in Africa has been likened to a statistical tragedy. Currently many statistical systems in Africa are being updated. This report from the statistical offices in Nigeria, Liberia and Zimbabwe documents that base year, data and methods used to generate GDP estimates currently date from 1990, 1992 and 1994. There is a growing need for macroeconomic statistics, but a
