Background: Experiments have shown improved cardiovascular stability in lambs if umbilical cord clamping is postponed until positive pressure ventilation is started. Studies on intact cord resuscitation on human term infants are sparse. The purpose of this study was to evaluate differences in clinical outcomes in non-breathing infants between groups, one where resuscitation is initiated with an in
Background: Endocrine disrupting chemicals (EDCs) are xenobiotics with the ability to interfere with hormone action, even at low levels. Prior environmental epidemiology studies link numerous suspected EDCs, including phthalates and bisphenol A (BPA), to adverse neurodevelopmental outcomes. However, results for some chemicals were inconsistent and most assessed one chemical at a time. Objectives:
Objective: To report the outcome after ruptured abdominal aortic aneurysm (rAAA) repair in octo- and nonagenarians from the Swedish Vascular Registry 1994-2014. Material and methods: 2335 intact AAA (iAAA) and 1538 rAAA were identified in patients aged 80 years and older. Crude, long-term, and relative survival data were analysed using the Kaplan-Meier method. Crude survival was calculated includi
Wohlers Associates, Inc., recognized widely as the leading consulting firm and preeminent authority on additive manufacturing and 3D printing worldwide—terms that are used interchangeably—today announced the publication of the Wohlers Report 2016. The 2016 edition marks the 21st consecutive year of its availability. According to Wohlers Report 2016, the additive manufacturing (AM) industry, consis
It is, with the thermal models used in today's building simulation progr¿rms,possible to calculate the major part of the heat transfer in a room with an ambientouter wall. However, there are some parameters these models calculatewith less or unknown accuracy: heat flows in poorly insulated walls or windows,heat flows in a room exposed to strong solar radiation, temperatures onthe inside of ambientAn ambient wall with a window were studied with both theoretical analyses and measurements performedunder conditions with natural climate. The method used wes to estimate the heat flow through wall and windowfrom measured temperatures and solar radiation. The longwave radiation was calculated from surface temperatures. The convective heat transfer was caculated as the difference between the heat f
AbstractBackgroundThere is a need for easily administered objective tests in neurodevelopmental disorders. We investigated the clinical utility for child and adolescent psychiatry of Auditory Brainstem Response (ABR) and Cambridge Neuropsychological Test Automated Battery (CANTAB) as support in diagnosing attention deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). MethodsTh
Aims/hypothesis: During the A/H1N1 2009 (A/California/04/2009) pandemic, mass vaccination with a squalene-containing vaccine, Pandemrix®, was performed in Sweden and Finland. The vaccination was found to cause narcolepsy in children and young adults with the HLA-DQ 6.2 haplotype. The aim of this study was to investigate if exposure to Pandemrix® similarly increased the risk of islet autoimmunity o
Aim: To evaluate three types of ventilation systems for operating rooms with respect to air cleanliness [in colony-forming units (cfu/m3)], energy consumption and comfort of working environment (noise and draught) as reported by surgical team members. Methods: Two commonly used ventilation systems, vertical laminar airflow (LAF) and turbulent mixed airflow (TMA), were compared with a newly develop
Background: Fishing communities around Lake Victoria in sub-Saharan Africa have been characterised as a population at high risk of HIV-infection. Methods: Using data from a cohort of HIV-positive individuals aged 13–49 years, enrolled from 5 fishing communities on Lake Victoria between 2009–2011, we sought to identify factors contributing to the epidemic and to understand the underlying structure
Our understanding and quantification of global soil nitrous oxide (N2O) emissions and the underlying processes remain largely uncertain. Here, we assessed the effects of multiple anthropogenic and natural factors, including nitrogen fertilizer (N) application, atmospheric N deposition, manure N application, land cover change, climate change, and rising atmospheric CO2 concentration, on global soil
Background: Prognoses of most adult Hodgkin lymphoma (HL) patients are excellent; most of them can achieve permanent remission that can be considered cured. However, many are under-treated or over-treated by standard modern therapies. An accurate determination of prognosis may allow clinicians to design personalised treatment according to individual risk of disease progression and survival. Lympho
Objective. To determine the concentrations of aggrecan fragments in synovial fluid from patients with knee joint injury, osteoarthritis (OA), or acute pyrophosphate arthritis (PPA; pseudogout), and to test their relative reactivity with the 846 epitope, a putative marker of cartilage aggrecan synthesis. Methods. Samples of knee joint fluid from 385 patients and 9 healthy-knee volunteers were obtai
The enzymatic interesterification of a solvent-free, equimolar mixture of trilaurin and 1,3-palmitin-2-olein was studied using three immobilized lipase preparations as catalysts. Analysis of triacylglycerol (TAG) content and fatty acid (FA) distribution monitored the lipase-catalyzed interesterification in sn-1,3 positions and FA exchange in the sn-2 position caused by acyl migration. Lipase from
Aim: The first Swedish National Guidelines for Ovarian Cancer (NGOC) were published in 2012. We aimed to evaluate surgical outcomes and survival in patients with stage IIIC-IV disease, before and after the NGOC implementation. Method: Women with primary epithelial ovarian cancer, FIGO stage IIIC–IV, registered in the Swedish Quality Registry for Gynecologic Cancer 2008–2011 and 2013–2016 were incl
Background: Avoidable mortality is considered as a potential indicator of the influences of public health policies and healthcare quality on population health. This study aimed to examine the trend in avoidable mortality and its influence on rising life expectancy (LE) and declining gender gap in LE (GGLE) in Sweden. Methods: We extracted data on causes of death by age, sex, and year from nationa
This paper is a comprehensive review of in-cycle closed-loop combustion controllers to achieve higher indicated efficiencies. Closed-loop combustion control reduces the effect of external disturbances and system uncertainties, which permit tighter safety margins and robust operation with a reduced calibration effort. The paper combines different components of previous investigations by the authors
Air pollution causes premature mortality and morbidity globally, but these adverse health effects occur over proportionately in low-and middle-income countries. Lack of both air pollution data and knowledge of its spatial distribution in African countries have been suggested to lead to an underestimation of health effects from air pollution. This study aims to measure nitrogen oxides (NOx), as wel
Purpose: Off-target binding in the skull and meninges is observed in some subjects undergoing tau positron emission tomography (PET) and could potentially differ between men and women. In this study we elucidate sex differences in tau off-target binding using three different tau PET tracers. Methods: 541 cognitively unimpaired amyloid-β negative participants underwent tau PET using [18F]flortaucip
Background: Gun violence is a global health problem. Population-based research on firearm-related injuries has been relatively limited considering the burden of disease. The aim of this study was to analyze nationwide epidemiological trends of firearm injuries. Methods: This is a retrospective nationwide epidemiological study including all patients with firearm injuries from the Swedish Trauma Reg
Introduction: The aim of the study is to compare the effect of cervical length measured with transvaginal ultrasound in the second trimester on the risk of spontaneous preterm delivery (PTD) between different risk groups of asymptomatic women with a singleton pregnancy. Material and methods: This is a pre-planned exploratory analysis of the CERVIX study, a prospective blinded multicenter diagnosti
