Helicobacter pylori Seropositivity, ABO Blood Type, and Pancreatic Cancer Risk From 5 Prospective Cohorts

BACKGROUND: Helicobacter pylori infection may be a risk factor for pancreatic cancer, particularly infection by strains without the cytotoxin-associated gene A (CagA) virulence factor. Non-O blood type is a known risk factor for pancreatic cancer, and H. pylori gastric colonization occurs largely from bacterial adhesins binding to blood group antigens on gastric mucosa.METHODS: We included 485 pan

Pancreatic cancer is associated with medication changes prior to clinical diagnosis

Patients with pancreatic ductal adenocarcinoma (PDAC) commonly develop symptoms and signs in the 1-2 years before diagnosis that can result in changes to medications. We investigate recent medication changes and PDAC diagnosis in Nurses' Health Study (NHS; females) and Health Professionals Follow-up Study (HPFS; males), including up to 148,973 U.S. participants followed for 2,994,057 person-years

Adipose tissue and skeletal muscle wasting precede clinical diagnosis of pancreatic cancer

Patients with pancreatic cancer commonly develop weight loss and muscle wasting. Whether adipose tissue and skeletal muscle losses begin before diagnosis and the potential utility of such losses for earlier cancer detection are not well understood. We quantify skeletal muscle and adipose tissue areas from computed tomography (CT) imaging obtained 2 months to 5 years before cancer diagnosis in 714

Being Breastfed in Infancy and Risk of Colorectal Cancer and Precursor Lesions

BACKGROUND & AIMS: Emerging evidence implicates the importance of perinatal and early-life exposures in colorectal cancer (CRC) development. However, it remains unclear whether being breastfed in infancy is associated with CRC risk in adult life, particularly early adulthood.METHODS: We prospectively investigated the association between history of being breastfed and risk of CRC and its precur

Gastrointestinal cancer precursor risk and mortality in pancreatic intraductal papillary mucinous neoplasms : a nationwide cohort study

BACKGROUND AND AIMS: Intraductal papillary mucinous neoplasm (IPMN) of the pancreas is a precursor of pancreatic cancer. While earlier research has shown a high prevalence of synchronous/metachronous extrapancreatic tumors in IPMN patients, these studies have often been small with retrospective data collection. The aim of the study was to examine absolute and relative risks of non-pancreatic gastr

TPP1 is associated with risk of advanced precursors and cervical cancer survival

It is unclear how telomere-binding protein TPP1 interacts with human telomerase reverse transcriptase (hTERT) and influences cervical cancer development and progression. This study included all eligible 156 cervical cancers diagnosed during 2003-2008 and followed up through 2014, 102 cervical intraepithelial neoplasia (CIN) patients, and 16 participants with normal cervix identified at the same pe

Protein biomarkers and alternatively methylated cell-free DNA detect early stage pancreatic cancer

OBJECTIVE: Pancreatic ductal adenocarcinoma (PDAC) is commonly diagnosed at an advanced stage. Liquid biopsy approaches may facilitate detection of early stage PDAC when curative treatments can be employed.DESIGN: To assess circulating marker discrimination in training, testing and validation patient cohorts (total n=426 patients), plasma markers were measured among PDAC cases and patients with ch

Artists-in-residence to foster more reflective modelling practices

One of the most prominent tools to explore sustainable futures are integrated assessment models (IAMs). Although IAMs have analytical strengths, their limitations risk closing-down imaginaries of sustainable futures. Critics therefore argue for a more ‘reflective’ IAM practice, where modellers critically question and reconsider their assumptions and explore futures and their role in climate policy

Olmesartan Restores LMNA Function in Haploinsufficient Cardiomyocytes

BACKGROUND: Gene mutations are responsible for a sizeable proportion of cases of heart failure. However, the number of patients with any specific mutation is small. Repositioning of existing US Food and Drug Administration-approved compounds to target specific mutations is a promising approach to efficient identification of new therapies for these patients. METHODS: The National Institutes of Heal

A validation of ultrasound as a diagnostic tool for the detection of testicular torsion

Background: Testicular torsion (TT) is a scrotal emergency that needs urgent detection for successful treatment. Purpose: To investigate the diagnostic value of acute ultrasound and the possibility of more effective detection. Material and Methods: This retrospective study included patients assessed with ultrasound for suspicion of TT between 2019 and 2023. Registration of parameters included symp

Current Developments in Malaria Vaccination : A Concise Review on Implementation, Challenges, and Future Directions

Introduction: Malaria remains a persistent challenge in global health, disproportionately affecting populations in endemic regions (eg, sub-Saharan Africa). Despite decades of international collaborative efforts, malaria continues to claim hundreds of thousands of lives each year, with young children and pregnant women enduring the heaviest burden. This concise review aimed to provide an up-to-dat

Achieving Distributed MIMO Performance with Repeater-Assisted Cellular Massive MIMO

In what ways could cellular massive MIMO be improved? This technology has already been shown to bring huge performance gains, however, coverage holes and difficulties to transmit multiple streams to multi-antenna users because of insufficient channel rank remain issues. Distributed MIMO, also known as cell-free massive MIMO, might be the ultimate solution. However, while being a powerful technolog

The Production of Gendered Knowledge of War : Women and Epistemic Power

This edited volume critically investigates women’s knowledge about war and explores the epistemic agency of women in a range of contemporary settings across the globe. Women are deeply affected by war, participate in war and resist war. At the same time, knowledge production often ignores and marginalizes women’s experiences and gendered ways of knowing war. From Colombia to Israel and Palestine,

Diagnosis of Alzheimer’s Disease by Canonical Correlation Analysis Based Fusion of Multi-Modal Medical Images

In recent years, the number of people with Alzheimer's disease (AD) has grown worldwide. Since no cure has yet been found for the disease, detection and initiation of treatment is the best way to prevent the disease from progressing behavioral and physical symptoms in the patient. There are several methods to diagnose AD, and neuroimaging, as a noninvasive approach, reveals changes in the brain du

LINE-1 retrotransposons mediate cis-acting transcriptional control in human pluripotent stem cells and regulate early brain development

Long interspersed nuclear element 1 (L1) retrotransposons represent a vast source of genetic variability. However, mechanistic analysis of whether and how L1s contribute to human developmental programs is lacking, in part due to the challenges associated with specific profiling and manipulation of human L1 expression. Here, we show that thousands of hominoid-specific L1 integrants are expressed in

In Situ Study of Axial GaSb/GaAs Nanowire Heterostructure Formation

Combining multiple III-V materials into axial nanowire heterostructures has enabled the fabrication of custom nanowire-based devices useful for a wide range of applications. However, our ability to form axial heterostructures between arbitrary combinations of III-V compounds is impeded by a lack of information on the dynamics of the heterojunction formation process, often resulting in suboptimal h
