Crit Rev Oncol Hematol

December 2024

Department of Hygiene and Epidemiology, University of Ioannina School of Medicine, 45110 Ioannina, Greece; Department of Epidemiology and Biostatistics, School of Public Health, Imperial College London, W12 0BZ London, UK. Electronic address:

Background: To contribute to the refinement of future physical activity (PA) guidelines, which have remained mostly generic until now, we performed an umbrella review of meta-analyses for PA in cancer survivors.

Methods: Medline and Scopus databases were searched in January 2024 for systematic reviews and meta-analyses on the association/effect of any type of PA in every cancer type and for any studied outcome. Statistically significant meta-analyses were categorized into four evidence groups (strong, highly suggestive, suggestive, weak) using pre-established grading criteria.

Spatiotemporal single-cell roadmap of human skin wound healing.

Cell Stem Cell

December 2024

Dermatology and Venereology Division, Department of Medicine Solna, Center for Molecular Medicine, Karolinska Institutet, 17176 Stockholm, Sweden. Electronic address:

Wound healing is vital for human health, yet the details of cellular dynamics and coordination in human wound repair remain largely unexplored. To address this, we conducted single-cell multi-omics analyses on human skin wound tissues through inflammation, proliferation, and remodeling phases of wound repair from the same individuals, monitoring the cellular and molecular dynamics of human skin wound healing at an unprecedented spatiotemporal resolution. This singular roadmap reveals the cellular architecture of the wound margin and identifies FOSL1 as a critical driver of re-epithelialization.

Sterile alpha motif and HD domain-containing protein 1 (SAMHD1) is a dNTP hydrolase important for intracellular dNTP homeostasis and serves as tumor suppressor and modulator of antimetabolite efficacy in cancer, though largely unexplored in breast cancer (BC). A cohort of patients with early BC (n = 564) with available gene expression data (GEP) was used. SAMHD1 protein expression was assessed by immunohistochemistry performed on tissue microarrays.

Objective: To investigate the prevalence and incidence of dementia in patients with non-overtly functional adrenal tumours (NOFATs).

Design: A national retrospective register-based study was conducted on patients diagnosed with NOFAT and controls diagnosed between 2005 and 2019, in Sweden. Individuals diagnosed with overt adrenal hormone excess or previous malignancies were excluded.

Introduction: The 2015 American Thyroid Association guidelines recommend de-escalating surgical treatment for papillary thyroid cancer (PTC). We hypothesize that the Dutch PTC population might differ due to a restrictive diagnostic policy that mainly selects symptomatic and palpable thyroid nodules for further diagnostics, potentially selecting relatively more aggressive tumors. We aimed to describe the Dutch PTC population because differences in populations can have consequences for the adoption of foreign guidelines.

Prioritizing cases from a multi-institutional cohort for a dataset of pathologist annotations.

J Pathol Inform

January 2025

U.S. Food and Drug Administration, Center for Devices and Radiological Health, Office of Science and Engineering Laboratories, Division of Imaging, Diagnostics, and Software Reliability, Silver Spring, MD, United States of America.

Objective: With the increasing energy surrounding the development of artificial intelligence and machine learning (AI/ML) models, the use of the same external validation dataset by various developers allows for a direct comparison of model performance. Through our High Throughput Truthing project, we are creating a validation dataset for AI/ML models trained in the assessment of stromal tumor-infiltrating lymphocytes (sTILs) in triple negative breast cancer (TNBC).

Materials And Methods: We obtained clinical metadata for hematoxylin and eosin-stained glass slides and corresponding scanned whole slide images (WSIs) of TNBC core biopsies from two US academic medical centers.

Background: The possibility of future parenthood is a highly relevant issue for patients of reproductive age facing oncologic treatment. This study aimed to investigate how fatherhood was achieved in a patient cohort of adolescents and young adults (AYAs) banking semen at time of cancer diagnosis and to determine the effectiveness of cryopreservation aimed at fertility preservation in the cohort.

Materials And Methods: Observational cohort study examining AYAs with a cancer diagnosis who underwent semen banking for fertility preservation at Karolinska University Hospital 1988-2020, as part of the Stockholm regional fertility preservation program.

Background: This systematic review analyzes the impact of COVID-19 on dementia patients' functional, cognitive, neuropsychiatric, and health related outcomes. It hypothesizes that dementia patients infected with SARS-CoV-2experience more pronounced deterioration compared to those who are uninfected.

Methods: Research from 01/03/2020 to 07/10/2023 was conducted using Medline, Web of Science, and Embase databases, and adhering to PRISMA guidelines and the PICO framework.

Introduction: Malaria remains a significant burden, and a fully protective vaccine against is critical for reducing morbidity and mortality. Antibody responses against the blood-stage antigen Merozoite Surface Protein 2 (MSP2) are associated with protection from malaria, but its extensive polymorphism is a barrier to its development as a vaccine candidate. New tools, such as long-read sequencing and accurate protein structure modelling allow us to study the genetic diversity and immune responses towards antigens from clinical isolates with unprecedented detail.

Aberration of mitochondrial function is a shared feature of many human pathologies, characterised by changes in metabolic flux, cellular energetics, morphology, composition, and dynamics of the mitochondrial network. While some of these changes serve as compensatory mechanisms to maintain cellular homeostasis, their chronic activation can permanently affect cellular metabolism and signalling, ultimately impairing cell function. Here, we use a Drosophila melanogaster model expressing a proofreading-deficient mtDNA polymerase (POLγ) in a genetic screen to find genes that mitigate the harmful accumulation of mtDNA mutations.

Aim: The association of cardiac implantable electronic devices (CIED), namely pacemaker (PM), implantable cardioverter-defibrillator (ICD) and cardiac resynchronization therapy with (CRT-D) or without defibrillator (CRT-P) with health-related quality of life (HRQoL) is lacking.

Methods And Results: Data from the Swedish Pacemaker and ICD Registry collected from January 2019 to February 2022 was used to analyze the responses to the European Quality of Life-5 Dimension questionnaire (EQ-5D) before and after one year of the CIED implant. Descriptive analysis was performed using Pearson's chi-square test, the analysis of variance ANOVA, the Kruskal-Wallis test and Wilcoxon signed-rank test when appropriate.

Type 2 diabetes mellitus and Parkinson's disease are chronic diseases linked to a growing pandemic that affects older adults and causes significant socio-economic burden. Epidemiological data supporting a close relationship between these two aging-related diseases have resulted in the investigation of shared pathophysiological molecular mechanisms. Impaired insulin signaling in the brain has gained increasing attention during the last decade and has been suggested to contribute to the development of Parkinson's disease through the dysregulation of several pathological processes.
