Populärvetenskaplig sammanfattning: Utvärdering av borrhålsloggar. Syftet med detta examensarbete var att göra en utvärdering av wireline borrhålsloggar från borrhålet Kyrkheddinge-4, 3 km öster om Staffanstorp i Skåne. Den undersökta delen av borrhålet Kyrkheddinge-4 befinner sig inom den potentiella reservoarsandstenen, Lundasandstenen. Wireline borrhålsloggar är geofysiska verktyg som används This study is an evaluation of formation characteristics, as derived from wire-line well logs, of the Lund Member in the borehole Kyrkheddinge-4, 3 km east of Staffanstorp, Skåne, Sweden, through the comparison to measured core data. The purpose is to assess the feasibility of using some of the porosity and permeability equations and cross-plots derived for the investigated section and applying th

China’s economic development has made a remarkable achievement over the past three decades. However, compared with other developed economies, it still mainly relies on coal resources as its primary energy. As country’s leading coal resources producer, Shanxi is now in an awkward position. A possible explanation is this region suffering “Resource Curse”: that the abundant resources did not bring ra

INTRODUCTION: Cognitive impairment is common in parkinsonian disorders, but its extent among older adults with subtle motor abnormalities without a diagnosed movement disorder remains unclear. We examined cognitive decline, domain-specific cognitive function and incident dementia in older adults with subthreshold parkinsonism and parkinsonism (primary analysis). Sensitivity analyses were repeated

Objective: To enable early prediction of strong traction force vacuum extraction. Design: Observational cohort. Setting: Karolinska University Hospital delivery ward, tertiary unit. Population and sample size: Term mid and low metal cup vacuum extraction deliveries June 2012 - February 2015, n = 277. Methods: Traction forces during vacuum extraction were collected prospectively using an intelligen

OBJECTIVES:The aim of this study was to apply a previously published method for evaluating radiographic progression, namely, predicted vs. observed radiographic progression in early rheumatoid arthritis (POPeRA), to the Swedish pharmacotherapy (SWEFOT) trial.METHOD:In SWEFOT, 487 patients with eRA were given methotrexate (MTX), and non-responders were randomized to group A [triple therapy: MTX+sul

Background: Patterns and determinants of long-term oral corticosteroid (OCS) use in asthma and related morbidity and mortality are not well-described. In a nationwide asthma cohort in Sweden, we evaluated the patterns and determinants of OCS use and risks of OCS-related morbidities and mortality. Methods: Data for 217 993 asthma patients (aged ≥ 6 years) in secondary care were identified between 2

Published meta-analyses indicate significant but inconsistent incident type-2 diabetes(T2D)-dietary glycemic index (GI) and glycemic load (GL) risk ratios or risk relations (RR). It is nowover a decade ago that a published meta-analysis used a predefined standard to identify validstudies. Considering valid studies only, and using random effects dose-response meta-analysis(DRM) while withdrawing sp

Background: Oncoplastic breast-conserving surgery allows larger resections in unfavorable locations, with an improved chance of preserving esthetics. Indications and timing for potential contralateral surgery to obtain symmetry are not clear. The aim of this study was to evaluate patient satisfaction after unilateral oncoplastic volume displacement surgery, to investigate potential risk factors fo

The homodimeric S100 protein calcyclin has been studied in the apo state by two-dimensional 1H NMR spectroscopy. Using a combination of scalar correlation and NOE experiments, sequence-specific 1H NMR assignments were obtained for all but one backbone and >90% of the side-chain resonances. To our knowledge, the 2 x 90 residue (20 kDa) calcyclin dimer is the largest protein system for which such co

Background: Coagulation activation is a hallmark of cancer, and anticoagulants have shown tumour-inhibiting properties. However, recent trials have failed to demonstrate improved survival with low-molecular-weight heparin (LMWH) in cancer populations. This has raised the question of suboptimal adherence as a possible explanation for the lack of benefit. Still, there is no standardised method to di

Objective: The occurrence of Helicobacter pylori (HP) and clarithromycin resistant HP (crHP) have not been investigated longitudinally in the Swedish childhood population. The aims were to study the prevalence of gastric HP-DNA and crHP strains in a cohort of children living in the southernmost parts of Sweden who were investigated with upper endoscopy between 2005 and 2016. Methods: HP colonisati

Plasma-free fatty acids (FFAs) are largely derived from adipose tissue. Elevated levels of FFA and fatty acidebinding protein 4 (FABP4), a key cytoplasmic chaperone of fatty acids, have been associated with adverse cardiovascular outcomes, but limited data are available on the relation of these biomarkers with cardiovascular and total mortality. We studied 4,707 participants with a mean age of 75

Background: Airway complications account for almost one third of anaesthesia-related brain damage and death. Immediate access to equipment enabling rescue airway strategies is crucial for successful management of unanticipated difficult airway situations. Methods: We conducted a nationwide survey of Swedish anaesthesiologists to analyse availability and organization of difficult airway trolleys (D

Objectives: Maintaining good cognitive function with aging may be aided by technology such as computers, tablets, and their applications. Little research so far has investigated whether internet use helps to maintain cognitive function over time.Design: Two population-based studies with a longitudinal design from 2001/2003 (T1) to 2007/2010 (T2).Setting: Sweden and the Netherlands.Participants: Ol

Ocular injury in the rabbit causes miosis and breakdown of the blood aqueous barrier (aqueous flare response, AFR), reflecting a sensory nerve-mediated inflammatory response, elicited by the release of tachykinins and calcitonin gene-related peptide (CGRP) from C-fibers. Neuropeptide Y (NPY) occurs in sympathetic fibers in the eye. The study was designed to examine whether NPY and related peptides

Background and purpose: Our purpose was to study the association between country of birth and incident epilepsy in second-generation immigrants in Sweden. Methods: The study population included all children (n = 4 023 149) aged up to 18 years in Sweden. Epilepsy was defined as at least one registered diagnosis of epilepsy in the National Patient Register. The incidence of epilepsy, using individua

BACKGROUND: Noroviruses are the major cause of viral gastroenteritis. Disease transmission is difficult to prevent and outbreaks in healthcare facilities commonly occur. Contact with infected persons and contaminated environments are believed to be the main routes of transmission. However, noroviruses have recently been found in aerosols and airborne transmission has been suggested. The aim of our

Healthy development of children in India is far from ensured. Proximate determinants of poor child health outcomes are infectious diseases and undernutrition, which are linked to socioeconomic status. In low- and middle-income countries, researchers rely on wealth indices, constructed from information on households’ asset ownership and amenities, to study socioeconomic disparities in child health.
