Numerous studies indicate that the frequency of extreme events such as droughts have increased particularly in the 20th century. Droughts are considered among the most costly natural disasters due to their impacts on crop yield, infrastructure, industry, and tourism. This thesis investigates historical global trends and patterns of droughts and drying areas. A satellite-based (model independent) c
In May 2011 Tetra Pak launched the first carton bottle for aseptic milk, the Tetra Evero Aseptic (TEA). This Master Thesis aims to give proposals on how the future development of the mechanism working as a dolly when the inductor is making the longitudinal sealing (LS) on the package in the A6 filling machine, should be continued. The current LS mechanism is not fulfilling the requirements in func
Objective To estimate the incidence of acute mesenteric ischaemia (AMI), proportions of its different forms and short-term and long-term mortality. Design Systematic review and meta-analysis. Data sources MEDLINE (Ovid), Web of Science, Scopus and Cochrane Library were searched until 26 July 2022. Eligibility criteria Studies reporting data on the incidence and outcomes of AMI in adult populations
Background: The textile dye mix (TDM) 6.6% in petrolatum contains Disperse Blue (DB) 35, Disperse Yellow 3, Disperse Orange (DO) 1 and 3, Disperse Red 1 and 17, and DB 106 and 124. The most frequent allergen in TDM-positive patients is DO 3. Around 85% of para-phenylenediamine (PPD)-allergic dermatitis patients have been positive to DO 3. There has been a discussion to exclude DO 3 from TDM 6.6% b
BackgroundThere is a need for the development of accurate, accessible and efficient screening instruments, focused on early-stage detection of neurocognitive disorders. The Geras Solutions cognitive test (GSCT) has showed potential as a digital screening tool for cognitive impairment but normative data are needed.ObjectiveThe aim of this study was to obtain normative data for the GSCT in cognitive
Objective: To develop machine-learning models that incorporate clinical information and radiomics features extracted from ultrasound images to distinguish uterine sarcomas from leiomyomas. Methods: This retrospective, multicenter, pilot case–control study included 200 patients (100 with a uterine sarcoma and 100 with a usual-type leiomyoma, i.e. including no benign leiomyoma variants) who underwen
Purpose: To evaluate if preoperative assessment with A Quick Test of Cognitive Speed (AQT) could increase the accuracy of predicting delirium after cardiac surgery compared to Mini-Mental State Examination (MMSE), and examine if a composite of variables, including cognitive function and depressive symptoms, could be useful to predict delirium. Patients and Methods: Cardiac surgery was performed in
Background: Diabetes mellitus (DM) is an established risk factor for intermittent claudication (IC) and other manifestations of atherosclerotic peripheral arterial disease. Indications for surgery in infrainguinal IC are debated, and there are conflicting reports regarding its outcomes in patients with DM. Aims of this study were to compare both short- and long-term effects on total- and cardiovas
BACKGROUND: Viral infections of the upper airways are the most common cause for absence from work or school, and there is evidence for probiotic efficacy in reducing the incidence and severity of these infections.OBJECTIVES: We aimed to confirm the previously reported beneficial effects of Lactiplantibacillus plantarum HEAL9 and Lacticaseibacillus paracasei 8700:2 against community-acquired common
Background: In a European study on contact allergy in the general population, it was hypothesized that the combination of contact allergy to a fragrance together with a history indicating dermatitis at exposure, and thereafter subsequent avoidance of scented products, implied a diagnosis of allergic contact dermatitis. Objectives: The primary aim of this study was to validate this hypothesis and a
Objectives Nocturnal hypoxia in obstructive sleep apnoea (OSA) is a potential risk factor for cancer. We aimed to investigate the association between OSA measures and cancer prevalence in a large national patient cohort. Design Cross-sectional study. Settings 44 sleep centres in Sweden. Participants 62 811 patients from the Swedish registry for positive airway pressure (PAP) treatment in OSA, link
AIM: To evaluate if the incidence of postoperative complications after gastrostomy placement is correlated to perioperative parameters or patient characteristics.METHODS: In this prospective observational study, children <18 years of age planned to receive a gastrostomy at partaking clinics between 2014 and 2019 were invited. Pre-, peri- and postoperative variables were collected and followed up 3
Background--The relationship between "on-treatment" low platelet reactivity and longitudinal risks of major bleeding dual antiplatelet therapy following acute coronary syndromes remains uncertain, especially for patients who do not undergo percutaneous coronary intervention. Methods and Results--We analyzed 2428medicallymanaged acute coronary syndromes patients fromthe Targeted Platelet Inhibition
It is crucial to consider the effects of large-scale drivers on species presences and ecological interactions to understand what structures communities. In our study, we investigated how the species composition and the potential interaction networks of herbivore and parasitoid communities in oilseed rape fields are affected by agricultural landscape characteristics. Insect communities of 26 winter
Mass migrations are a phenomenon of all times. Notably, following the Second World War, there have been huge migration movements and decolonisation processes, particularly by the Germans and the Jews, but also by Roma and other groups. Parallel to that, in 1963, Protocol No. 4 to the Convention was signed, with Article 4 prohibiting the collective expulsion of aliens. In 2020, 3,6% of the populati
Within the field of medical radiation protection, radiation safety and personal dosimetry, there is a constant pursuit for improving existing methods and evaluating new approaches for measuring and quantifying the radiation doses that hospital staff may be exposed to in their clinical work. There are numerous ways of determining what doses the staff are being exposed to and the most commonly used
Swedish Match experiences a changing business environment with increased competition. In this business environment, the ability to successfully utilizing technological advances, such as big data and IoT, is becoming more important to remain competitive. In addition, a limited number of studies have been conducted on the theme big data and IoT in a manufacturing firm. Thus, this master’s thesis is
Bakgrund: Studier visar på att ljudnivån på en intensivvårdsavdelning är hög. I många studier har man kommit fram till att en stor del av ljudet orsakas av samtal mellan personal. Samtal svarar för 26% av allt ljud på en intensivvårdsavdelning. Sömn är en grundläggande komponent för att återställa energi och fysisk hälsa efter sjukdom. Upp till 58 % av alla patienter som sover vaknar på grund av o
The growing need for human-machine interfaces (HMIs) underscores the importance of sensory feedback, with electrical stimulation offering efficient interaction in various applications. While its sensory effects are extensively studied, investigations into the reaction time (RT) following transcutaneous electrical stimulation (TES) remain limited. This study aimed to evaluate how stimulation parame
BECC Biodiversity and Ecosystem services in a Changing Climate 2 The vision of BECC is to provide a world-leading research environment, bringing together excellent research and training at Lund University and the University of Gothenburg, to address society’s growing need for scientific knowledge to inform the consideration of biodiversity and ecosystem services in policy formulation and decision-
