Groundwater contamination by nitrate is a common problem in many parts of the world. The agriculturally important Shimabara district in Nagasaki, Japan, is experiencing this problem. The general source of drinking water of the study area is groundwater and consequently the nitrate contamination is a significant problem. For this reason, a groundwater investigation was performed and water samples w
Studies showing that large-scale public health interventions in early life have lasting economic consequences are still scarce and rarely disclose the mechanisms. Being born in a hospital versus having a traditional birth attendant at home represents the most common early life policy change worldwide. Knowing the consequences of this policy is also important given the ongoing enlargement of matern
Background: The Osborn or J-wave, an upright deflection of the J-point on the electrocardiogram (ECG), is often observed during severe hypothermia. A possible relation between Osborn waves (OW) and increased risk of ventricular arrhythmia has been reported. We sought to determine whether the level of targeted temperature management (TTM) following out-of-hospital cardiac arrest (OHCA) affects the
In order to elucidate the multidimensional response mechanism for migration of antibiotics and spread of resistome in riverbed driven by river water level fluctuations, dynamic reactors were set up to simulate the variation of sulfamethazine vertical migration, biotransformation and resistance genes expression according to fluctuation direction and magnitude. The upward fluctuation of water level
Black carbon (BC) is produced by incomplete combustion of biomass and fossil fuels and is released as aerosols to the atmosphere with effects on the climate, environment, and human health. Current BC emissions are well monitored in many parts of the world. However, the geographical coverage is limited, and historical records of BC accumulation are still scarce. Here we present a quantification of
This work presents an alternative cetane rating method using a production compression ignition (CI) engine, offering an accessible approach for preliminary fuel evaluation without the need for specialized equipment. As part of this work, an empirical correlation was developed linking ignition delay (ID) to both the cetane number (CN) and intake oxygen concentration. The test method follows the pri
BackgroundThe captive bolt gun is a tool for stunning animals in the meat industry and is not considered a firearm under the Swedish firearm legislation. This study aimed to explore the involvement of such devices in human fatalities, with an emphasis on suicides. Epidemiological characteristics from a longitudinal perspective, as well as risk factors and injury patterns were analyzed.MethodSuicid
Background: Prolonged time to surgery (TTS) after neoadjuvant chemoradiotherapy (nCRT) may enable malnourished oesophageal cancer patients' nutritional status to recover better, possibly improving outcomes with fewer complications and better overall survival (OS) after oesophagectomy. Methods: This is a substudy within a multicentre randomised controlled trial comparing outcomes in patients with o
BackgroundBreathlessness is a common and distressing symptom across a wide range of medical conditions. Different aspects (dimensions) of breathlessness can be assessed using the Multidimensional Dyspnoea Profile (MDP) and Dyspnoea-12 (D12) questionnaires. We aimed to examine whether the order of completing MDP and D12 affects the breathlessness responses in people with cardiorespiratory disease.M
The efficiency and stability of wide bandgap (WBG) perovskite solar cells (PSCs) are constrained by photo-induced halide segregation and severe non-radiative recombination, which significantly impedes the advancement of high-efficiency and stable perovskite/silicon tandem solar cells (PSTSCs). In this work, a potassium 4-sulfonic-1,8-naphthalic anhydride salt (4S-NAPS), featuring dual-anchoring si
Purpose: This study aimed to evaluate the ability of a thigh-worn accelerometer to detect walking during daily life in individuals with Lumbar Spinal Stenosis (LSS). Two hypotheses were made regarding how walking measurements from the accelerometer, a walking test, and an ankle-worn StepWatch would relate in order for the accelerometer to be valid. The hypotheses were: (a) there is no difference b
Biomass gasification gas (BGG), a carbon-neutral renewable fuel and important hydrogen carrier, holds significant promise for sustainable energy systems. However, its practical implementation is challenged by combustion instability and elevated NOx emissions, primarily due to localized high-temperature zones induced by the hydrogen content. MILD (Moderate or Intense Low-oxygen Dilution) combustion
Disinhibition of the mechanistic target of rapamycin (mTOR) pathway has been observed in patients with loss-of-function variants in the disheveled, Egl-10, and pleckstrin domain-containing protein 5 (DEPDC5), and nitrogen permease regulator-like proteins 2 and 3 (NPRL2, and NPRL3) genes, which encode the components of GTPase activating protein Activity Toward Rags Complex 1 (GATOR1) complex. Evero
BackgroundPreliminary results from the SNAP trial presented at ESCMID Global 2025 reported a high incidence (19.8%) of acute kidney injury (AKI) in patients treated with (flu)cloxacillin for Staphylococcus aureus bacteraemia (SAB).ObjectiveIn Sweden, cloxacillin is used at lower daily doses, and the risk of nephrotoxicity has not been assessed in this setting.MethodsWe retrospectively evaluated re
Background: The Peritoneal Cancer Index recorded at laparotomy is based on visual and palpable inspection of peritoneal surfaces for disease. This study aimed to analyze interobserver variation in assigning the lesion score (LS) and morphologic term (MT) to characterize peritoneal lesions (PL) and predict the probability of malignancy (POM) among surgeons with expertise in cytoreductive surgery (C
Background The aim of this systematic review and meta-analysis was to examine autoantibody positive individuals and define: (a) the relative risk of rheumatoid arthritis (RA) compared with autoantibody negative individuals and (b) the cumulative incidence of RA over time, in different populations. Methods A systematic literature search was performed in August 2025. Retrospective case control studi
Background Multimorbidity, the co-occurrence of two or more non-communicable diseases (NCDs), is common and has been linked to venous thromboembolism (VTE). Whether multimorbidity diagnosed in primary-care is associated with incident VTE remains unclear. We aimed to examine this association. Methods Multimorbidity was defined using Swedish primary-care data. Individuals without prior VTE were incl
Purpose: This paper aims to explore Swedish municipalities’ adoption of politically decided goals and targets, within the budget document, that are formulated for the accounting unit of the municipal group. Design/methodology/approach: A regression analysis of the adoption of financial and non-financial performance measurement by 289 Swedish municipalities was performed, including eight independen
