The “Warburg effect”, a metabolic adaptation observed in dividing cells, involves a shift from mitochondrial oxidative phosphorylation to cytoplasmic glucose metabolism. This metabolic process is characterized by increased cellular uptake of glucose and glutamine, elevated intracellular pH and sodium levels, enhanced protection against oxidative stress, altered autophagy, and increased lactate pro
The hippocampus, crucial in cognitive aging and Alzheimer’s disease (AD), shows early atrophy during disease progression. This study investigated 5-year trajectories of hippocampal volumes across AD stages, focusing on genetic predisposition to AD, captured through the polygenic risk score for AD (PRS-AD) and APOE, and their impact on hippocampal atrophy. Analyzing data from 1,051 participants in
Abstract Introduction: Epidemiologic studies of hidradenitis suppurativa (HS) from Sweden are limited. The aim of this study was to investigate the prevalence of HS in Lund and Gothenburg, Sweden. Methods: This study was a part of the Global Hidradenitis Suppurativa Atlas (GHiSA) initiative. The study was multicentered and included apparently healthy adults accompanying a patient to the Department
Objective: There is a well-established association of oral manifestations in the non-infectious chronic diarrhoeal conditions namely, Morbus Crohn, ulcerative colitis, and coeliac disease. Such a connection may exist also for the remaining non-infectious chronic diarrhoeal conditions, that is irritable bowel syndrome (IBS) and microscopic colitis (MC). Materials and methods: A systematic search wa
Background: Nocturnal gastro-oesophageal reflux (nGER) is common in people with respiratory diseases, but its association with pulmonary abnormalities is not known. Aim: Investigate the association between nGER and pulmonary abnormalities on chest CT in an adult general population. Methods: In total, 28 846 individuals from the general population aged 50-64 years completed questionnaires and under
In applied psychology, ontological assumptions are rarely subjected to scrutiny. Yet ontological positionings will affect all aspects of a research undertaking. Assumptions about what is real—and what is not—will affect conceptualization, study design, and analytical focus. In the investigation of social influence, failure to engage with ontological positionings has resulted in a default ontology
AIM: This retrospective observational cohort study aimed to investigate the prevalence of suspected lateral lymph node metastases (LLNM), as diagnosed by magnetic resonance imaging (MRI), and its impact on local recurrence (LR) and overall survival (OS). Patients who underwent dissection of suspected lymph nodes were evaluated in subgroup analysis.METHOD: Patients diagnosed with rectal cancer in S
A recent debate has emerged between Caspar et al. (2024) and Herculano-Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought-provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according to us leads to oversimplified conclusions. We use this e
BackgroundLong-term oxygen therapy (LTOT) given for at least 15 hours/day improves survival in patients with severe chronic hypoxemia. However, the recent REDOX trial showed that LTOT prescribed for 24 hours/day was not superior to 15 hours/day in terms of death, hospitalizations, or self-reported outcomes. We aimed to examine the cost effectiveness of prescribing LTOT for 24 versus 15 hours/day.M
The impact of amyloid-β (Aβ) accumulation on regional brain atrophy in preclinical Alzheimer’s disease (AD), and its interaction with risk factors like sex and APOE -ε4 carriership, remains unclear. In this study, we examined these associations in a population of older adults without dementia and evaluated the potential of Aβ-PET for risk stratification. We included 1329 participants (56 % female)
The recent COVID-19 pandemic has considerably impacted negatively on many aspects of human life such as access to basic necessities including water, energy and food. This article aims to investigate the impact of the COVID-19 lockdown on the water, energy and food accessibility in Katsina state, Nigeria. The survey involved the administration of a questionnaire to a total of 900 households out of
Background: The 2015 Lancet Commission on global surgery identified surgery and anaesthesia as indispensable parts of holistic health-care systems. However, COVID-19 exposed the fragility of planned surgical services around the world, which have also been neglected in pandemic recovery planning. This study aimed to develop and validate a novel index to support local elective surgical system streng

Micropollutant removal is a key component of the revised Urban Wastewater Treatment Directive (UWWTD) and can be achieved with ozonation. During ozonation, the composition of the wastewater matrix and the targeted treatment level for individual micropollutants or groups of such compounds affect ozone consumption. In this work, it was hypothesized that nitrite scavenging, the point of dosing (befor
OBJECTIVES: Iron deficiency, anaemia, and menorrhagia - or heavy menstrual bleeding - are interrelated conditions that are highly prevalent and commonly underrecognised in exercising females of reproductive age. This study utilised a screening tool to identify risk factors and symptoms associated with heavy menstrual bleeding, iron deficiency, and anaemia in this population.DESIGN: An observationa
BACKGROUND: Alzheimer's disease pathology can be accurately identified with blood biomarkers (core 1 biomarkers), including plasma p-tau217 tests. Biomarkers that change longitudinally after diagnosis (core 2 biomarkers) can increase confidence that Alzheimer's disease pathology is contributing to cognitive symptoms. Plasma eMTBR-tau243 reflects tau tangle pathology and is a promising core 2 bioma
High-altitude lakes and headwater streams of the Andes provide essential benefits to society, yet they remain among the least studied and most vulnerable freshwater ecosystems. These systems supply drinking water, support agriculture and grazing, regulate floods, store carbon, and hold deep cultural and spiritual value for local communities. However, climate change, land use change, water extracti
