One can falsely assume that it is well known that bacteremia is associated with higher mortality in sepsis. Only a handful of studies specifically focus on the comparison of culture-negative and culture-positive sepsis with different conclusions depending on study design. The aim of this study was to describe outcome for critically ill patients with either culture-positive or -negative sepsis in a

PURPOSE: The "Shrunken pore syndrome" (SPS) is characterized by a difference in renal filtration between cystatin C and creatinine, resulting in a low eGFRcystatinC /eGFRcreatinine -ratio. Studies have demonstrated a high risk for cardiovascular morbidity and mortality for patients with SPS. In this discovery study, we explored associations between SPS and proteins implicated in cardiovascular dis

INTRODUCTION: Acute kidney injury (AKI) is a common problem in hospitalized patients, requiring extensive treatment and carries a high mortality rate. This study was designed to assess the epidemiology of AKI, and risk factors and outcome of patients with severe AKI in a tertiary care university hospital in Iceland.MATERIAL AND METHODS: All adult patients with measured serum creatinine (SCr) in La

The S-scheme mechanism in photocatalysis offers a promising approach to significantly enhance photoreductive activity. Here, using Bi dots as electronic media, and by changing the amount of added C@CuO on the surface of flower-shaped Bi2MoO6, a diverse range of CBM-x heterojunctions, were synthesized using a multi-step approach that incorporated solvothermal preparation and calcination methods. CB

Vi spenderar en tredjedel av våra liv sovandes och sömn är en avgörande faktor för god hälsa och välbefinnande. Men det är även viktigt att erkänna sömnens komplexitet, eftersom det är flera faktorer som kan påverka sömnen. Både biologiska, kontextuella och psykosociala faktorer har inverkan på ungdomarnas sömn. Otillräcklig sömn, sömnproblem och symptom på insomni är vanligt hos ungdomar. SömnlösInsufficient sleep, sleep problems and insomnia are common in adolescents, and insomnia and insufficient sleep are public health concerns that can impact adolescents’ mental and physical health. There are several different treatments for sleep problems and insomnia, and there is a great focus on the problem when it has already arisen. However, since this is a public health problem, it is important

Purpose: The relationship between prostate-specific antigen (PSA) level and prostate cancer risk remains subject to fundamental disagreements. We hypothesized that the risk of prostate cancer on biopsy for a given PSA level is affected by identifiable characteristics of the cohort under study. Experimental Design: We used data from five European and three U.S. cohorts of men undergoing biopsy for

Background: Increasing evidence suggests a link between type 1 diabetes (T1D) and intake of gluten, but no controlled trials have examined whether a gluten-free diet (GFD) has positive effects on glycemic control in children with T1D. Methods: We conducted a non-randomized feasibility study. Twenty-three children with newly diagnosed T1D were included and either followed a GFD (n = 14) or a normal

OBJECTIVE: To describe the distribution of HIV-1 variants in population-based national surveys conducted in sub-Saharan African countries between 2015 and 2022.DESIGN: Multicountry analysis.METHODS: Sixteen population-based national surveys, conducted between 2015 and 2022, were analyzed. Survey participants were eligible if HIV genotyping was successful. In most countries, people with HIV (PWH) w

Obesity is a chronic disease with a significant and growing impact on Canadians. The “Awareness, Care and Treatment In Obesity MaNagement” (ACTION) Study investigated perceptions, attitudes and perceived barriers to obesity management among Canadian people with obesity (PwO), healthcare providers (HCPs) and employers. In this study adult PwO (body mass index ≥30 kg/m2, based on self-reported heigh

Diffuse nitrate pollution remains a persistent threat to drinking-water resources, yet current predictive frameworks rarely capture how the spatial composition (land-cover fractions) and configuration (landscape fragmentation) of land systems jointly modulate leaching. This study presents a novel multiscale framework integrating hydro-climatic, soil and anthropogenic predictors with land-cover fra

Strut-based structures, such as lattices, produced using additive manufacturing (AM) offer significant potential for applications requiring lightweighting and structural compliance. However, conventional Design for AM (DfAM) approaches often assume idealised material behaviour, which can be misleading for thin strut-based structures where geometric parameters and process-induced effects significan

PurposeThe purpose of this paper is to present an experimental study which aims at assessing the potentially misleading effect of graphic elements on food packaging. The authors call these elements potentially misleading elements (PMEs) as they can give customers false expectations. They are either highlighted numerical information (30 per cent fibre, 8 per cent fat, 100 per cent natural […]) or p

With the diminishing reserves of oil and the growing public concern for environmental issues, the end of gasoline powered vehicles is getting closer each year. To prevent this from causing the personal and comfortable way of transportation mankind has gotten used to, to die with them, an alternative without the downsides of the gasoline engine must be developed. The environmentally friendly electr

Purpose The purpose of this research is to explore the effects of format development of an original single-format general merchandise retailer on store image. Theoretical Perspectives This study is grounded on the alignment of existing literature in the fields of format development and store image.

In this thesis work, a highly linear passive attenuator and mixer were designed to be used in a wide-band Transmission Observation Receiver (TOR). The TOR is a low IF receiver that accepts RF frequencies from 2GHz to 7GHz, and produces corresponding IF bandwidths of 280MHz to 990MHz respectively, using low side LO injection. The dynamic range is maximized by using passive topologies for both the a

Virusinfektioner har utan tvekan blivit det största hälsoproblemet i världen. I skrivande stund når antalet COVID-19 infektioner i världen upp emot 151 800 000 vilket gör att behovet av vacciner och antivirala läkemedel är viktigare nu än någonsin tidigare. Influensa A är ytligare ett virus som orsakar överdödlighet, trotts att många klarar sig lindrigt vid infektion. För att kunna förhindra ellerWith viral infections becoming an ever-increasing health problem in the world, the study of viral proteins is a cornerstone for understanding and preventing future pandemics. The following work shows the purification and structural characterization of the Influenza A M2 proton channel through solid-state NMR (ssNMR). Despite previously published structures of the M2 proton channel, the method of p

Batterier möjliggör mer solel än elnätet tidigare klarat av En ökad andel solenergi i elnätet ställer nya tuffa krav på det befintliga nätet. I det här examensarbetet har möjligheten att undvika nätförstärkning genom att istället installera batterier på väl valda platser i nätet undersökts. Med hjälp av lösningen kan mer solel än nätet tidigare klarat av installeras. Historiskt sett har el produThis thesis addresses overvoltage issues in weak low voltage grids caused by large solar power production. The suggested method is using PI controllers to control voltage. This is done by using battery energy storage systems (BESS), designed to absorb active power during these times and thereby limiting the voltage rise. This could enable faster integration of solar power and a reduced demand for
