Objective: The association between mammographic density (MD) and breast cancer (BC) recurrence and survival remains unclear. Patients receiving neoadjuvant chemotherapy (NACT) are in a vulnerable situation with the tumor within the breast during treatment. This study evaluated the association between MD and recurrence/survival in BC patients treated with NACT. Methods: Patients with BC treated wit
Background A 1-h algorithm based on high-sensitivity cardiac troponin T (hs-cTnT) testing at presentation and again 1 h thereafter has been shown to accurately rule out acute myocardial infarction. Objectives The goal of the study was to evaluate the diagnostic accuracy of the 1-h algorithm when supplemented with patient history and an electrocardiogram (ECG) (the extended algorithm) for predicti
Background: Increased solar and geomagnetic activity (SGA) may alter sympathetic nervous system activity, reduce antioxidant activity, and modulate physiochemical processes that contribute to atmospheric aerosols, all which may reduce pulmonary function. Objectives: Investigate associations between forced expiratory volume at 1 s (FEV1) and forced vital capacity (FVC) with SGA, and assess whether
Global warming is one of the most important environmental issues from the last few decades and is causing climate change due to carbon dioxide (CO2) emissions and other greenhouse gases (GHG) emissions. Therefore, examination of atmospheric CO2 concentration (XCO2) variations on the local and global scale is critical. The purpose of this research was to analyze the role of environmental variables
Interpreting the social complexity of the Roman house requires a careful evaluation of existing evidence. With this in mind, recent work in the field has proposed a variety of different approaches, focusing each time on a specific type of source (architecture and décor, ancient texts, material evidence from excavated houses), each in turn recursively deemed more adequate for the purpose or more fr
As climate has warmed significantly over past decades, numerous studies have confirmed a pattern of more frequent and more intense hydro-climate events across the globe, such as floods, heatwaves, and droughts. Analyzing the variability of climate events with reliable historical data records is one of the most direct approaches for understanding its patterns of change. The development of climate m
PURPOSE: To describe the clinical presentation and treatment outcomes in a nationwide cohort of patients with giant prolactinomas. METHODS: Register-based study of patients with giant prolactinomas [serum prolactin (PRL) > 1000 µg/L, tumor diameter ≥40 mm] identified in the Swedish Pituitary Register 1991-2018. RESULTS: Eighty-four patients [mean age 47 (SD ±16) years, 89% men] were included in th
Groundwater contamination is a threat to drinking water resources and ecosystems. Remediation by injection of chemical reagents into the aquifer may be preferred to excavation to reduce cost and environmental footprint. Yet, successful remediation requires complete contact between contamination and reagents. Subsurface heterogeneities are often responsible for diffusion into low-permeable zones, w
Few germline mutations are known to affect lung cancer risk. We performed analyses of rare variants from 39,146 individuals of European ancestry and investigated gene expression levels in 7,773 samples. We find a large-effect association with an ATM L2307F (rs56009889) mutation in adenocarcinoma for discovery (adjusted Odds Ratio = 8.82, P = 1.18 × 10−15) and replication (adjusted OR = 2.93, P = 2
The master regulator of neuroendocrine differentiation, achaete-scute complex homolog 1 (ASCL1) defines a subgroup of lung adenocarcinoma. However, the mechanistic role of ASCL1 in lung tumorigenesis and its relation to the immune microenvironment is principally unknown. Here, the immune landscape of ASCL1-positive lung adenocarcinomas was characterized by immunohistochemistry. Furthermore, ASCL1
The risk for type 1 diabetes is strongly associated with HLA-DQ and the appearance of beta cell autoantibodies against either insulin, glutamate decarboxylase (GAD65), insulinoma-associated protein-2 (IA-2), or zinc transporter 8 (ZnT8). Prolonged exposure to autoantibodies may be related to T cell exhaustion known to occur in chronic infections or autoimmune disorders. It was hypothesized that au
Type-2 diabetes (T2D) is a global disease caused by the inability of pancreatic β-cells to secrete adequate insulin. However, the molecular mechanisms underlying the failure of β-cells to respond to glucose in T2D remains unknown. Here, we investigated the relative contribution of UDP-glucose (UDP-G), a P2Y14-specific agonist, in the regulation of insulin release using human isolated pancreatic is
I och med Hu Jintaos och Wen Jiabaos tillträde till makten har den kinesiska regeringens fokus kommit att flyttas från ren ekonomisk utveckling till att i högre grad än tidigare fokusera på att minska klyftorna mellan stad och landsbygd. Denna uppsats undersöker några av de problem som centralregeringen ser på landsbygden idag, samt några av de lösningar som presenterats. I undersökningen av situaSince Hu Jintao and Wen Jiabao took office the focus of the Chinese government has been less on pure economic development than before and more on developing the countryside. This paper investigates some of the problems the central government sees in the countryside as well as some of their solutions to those problems. The book The Grain People: Will China’s Villages Disappear? (Liangmin－Zhongguo n
Introduction: HIV guidelines recommend switching from a three-drug regimen (3DR) to dolutegravir + lamivudine (DTG+3TC) for eligible individuals. This retrospective national cohort study used Swedish InfCareHIV registry data to evaluate long-term outcomes of adults with HIV RNA <50 copies/ml who switched to DTG+3TC or a guideline-recommended 3DR between July 2019 and May 2023 in routine clinical c
Moisture‐induced deterioration is critical to building envelope durability in cold and temperate climates. To propose a new framework for selecting moisture design periods (MDPs) in Swedish building assemblies that capture sever moisture conditions more accurately, this paper evaluates different methods for producing MDPs. Using a 30‐year historical weather dataset as a benchmark, we compared simu
Digitala D2C-företag i traditionellt fysiska branscher kan etablera en tydlig nisch, men möter nya utmaningar när affärsmodellen ska skalas till fler kundsegment. Detta examensarbete undersöker hur ett svenskt digitalt D2C-företag inom målarfärgsbranschen kan vidareutveckla en validerad, nischad och digital affärsmodell för att nå nya kundsegment på den svenska marknaden. Studien genomförs som enDigital D2C companies in traditionally physical retail can establish a clear niche, but face new challenges when the business model is scaled to broader customer segments. This thesis explores how a Swedish company in the paint industry can further develop a validated, niche-oriented, and digital business model to reach new customer segments in the Swedish market. The study is conducted as a case
Arrhythmogenic right ventricular cardiomyopathy (ARVC) and cardiac sarcoidosis (CS) can show significant overlap in their clinical presentation. Differentiation between both is crucial for optimal patient management. Aim of this study is to develop an ECG-based machine learning model to distinguish between ARCV and CS patients. The study population included 100 patients (50 with ARCV and 50 with C
Objectives: Positive resection margins after breast-conserving surgery (BCS) most often demands a repeat surgery. To preoperatively identify patients at risk of positive margins, a multivariable model has been developed that predicts positive margins after BCS with a high accuracy. This study aimed to externally validate this prediction model to explore its generalizability and assess if additiona
This article conducts a multi-scalar analysis of the dynamics between secularism and religion in contemporary Sweden and highlights a growing divide between them, in the wake of neoliberal reconfigurations of the welfare state and a stronger religious pluralism in public space. Through an analysis of the public debate around conversion attempts and state funding for religious organizations, we exp
Esophageal lesions are common findings in disorders of the digestive tract in patients living with HIV, the most typical symptoms being odynophagia and/or dysphagia. This article provides a narrative review of the spectrum of esophagitis in patients living with HIV, focusing on fungal, viral, bacterial and non-infectious etiologies, as well as co-infections with viral hepatitis viruses. The articl
