BKPyV DNAemia in Kidney Transplant Recipients Undergoing Regular Screening: A Single-Centre Cohort Study.

Infection with BK polyomavirus (BKPyV) is a common opportunistic infection after kidney transplantation (KT) and may affect graft function. We aimed to determine the incidence, risk factors, and clinical outcomes of BKPyV DNAemia in a prospective cohort of 601 KT recipients transplanted from 2012 to 2020. BKPyV PCR on plasma was performed at days 60, 90, 180, 270, and 360 post-KT.

Pseudouridine guides germline small RNA transport and epigenetic inheritance.

Epigenetic modifications that arise during plant and animal development, such as DNA and histone modification, are mostly reset during gamete formation, but some are inherited from the germline including those marking imprinted genes. Small RNAs guide these epigenetic modifications, and some are also inherited by the next generation. In , these inherited small RNAs have poly (UG) tails, but how inherited small RNAs are distinguished in other animals and plants is unknown.

Effect of a lifestyle intervention to prevent weight gain at initiation of insulin pump therapy in type 2 diabetes: A randomized, controlled, multicentre trial.

Unlabelled: Insulin pump therapy improves glycaemic control in individuals with type 2 diabetes. However, it may be associated with weight gain.

Aim: To test the effectiveness of a six-month dietary and physical activity intervention, compared to usual care, on weight gain prevention after initiation of insulin pump.

Interrupting Endocrine Therapy to Attempt Pregnancy after Breast Cancer.

Background: Prospective data on the risk of recurrence among women with hormone receptor-positive early breast cancer who temporarily discontinue endocrine therapy to attempt pregnancy are lacking.

Methods: We conducted a single-group trial in which we evaluated the temporary interruption of adjuvant endocrine therapy to attempt pregnancy in young women with previous breast cancer. Eligible women were 42 years of age or younger; had had stage I, II, or III disease; had received adjuvant endocrine therapy for 18 to 30 months; and desired pregnancy.

Association between ten-eleven methylcytosine dioxygenase 2 genetic variation and viral load in people with HIV.

Introduction: Identifying genetic factors that influence HIV-pathogenesis is critical for understanding disease pathways. Previous studies have suggested a role for the human gene ten-eleven methylcytosine dioxygenase 2 (TET2) in modulating HIV-pathogenesis.

Methods: We assessed whether genetic variation in TET2 was associated with markers of HIV-pathogenesis using both gene level and single nucleotide polymorphism (SNP) level association in 8512 HIV-positive persons across five clinical trial cohorts.

Replicative Instability Drives Cancer Progression.

In the past decade, defective DNA repair has been increasingly linked with cancer progression. Human tumors with markers of defective DNA repair and increased replication stress exhibit genomic instability and poor survival rates across tumor types. Seminal studies have demonstrated that genomic instability develops following inactivation of BRCA1, BRCA2, or BRCA-related genes.

Patient perspectives on testing for clonal hematopoiesis of indeterminate potential.

Clonal hematopoiesis of indeterminate potential (CHIP), an emerging biomarker for personalized risk-directed interventions, is increased in cancer survivors. However, little is known about patient preferences for CHIP testing. We surveyed participants in a prospective cohort study of young women with breast cancer (BC).

Coping strategies and anxiety in young breast cancer survivors.

Purpose: We sought to describe coping strategies reported by young breast cancer survivors and evaluate the relationship between utilization of specific coping strategies and anxiety in survivorship.

Methods: Participants enrolled in The Young Women's Breast Cancer Study, a multi-center, cohort of women diagnosed with breast cancer at age ≤ 40 years, completed surveys that assessed demographics, coping strategies (reported at 6-month post-enrollment and 18-month post-diagnosis), and anxiety (2 years post-diagnosis). We used univariable and multivariable logistic regression to examine the relationship between coping strategies and anxiety.

High-Sensitivity Troponin I after Cardiac Surgery and 30-Day Mortality.

Background: Consensus recommendations regarding the threshold levels of cardiac troponin elevations for the definition of perioperative myocardial infarction and clinically important periprocedural myocardial injury in patients undergoing cardiac surgery range widely (from >10 times to ≥70 times the upper reference limit for the assay). Limited evidence is available to support these recommendations.

Methods: We undertook an international prospective cohort study involving patients 18 years of age or older who underwent cardiac surgery.

Prevalence and Outcomes for Heavily Treatment-Experienced Individuals Living With Human Immunodeficiency Virus in a European Cohort.

Background: Although antiretroviral treatments have improved survival of persons living with HIV, their long-term use may limit available drug options. We estimated the prevalence of heavily treatment-experienced (HTE) status and the potential clinical consequences of becoming HTE.

Setting: EuroSIDA, a European multicenter prospective cohort study.

Genetic predisposition to hypertension is associated with preeclampsia in European and Central Asian women.

Preeclampsia is a serious complication of pregnancy, affecting both maternal and fetal health. In genome-wide association meta-analysis of European and Central Asian mothers, we identify sequence variants that associate with preeclampsia in the maternal genome at ZNF831/20q13 and FTO/16q12. These are previously established variants for blood pressure (BP) and the FTO variant has also been associated with body mass index (BMI).

Tucatinib, Trastuzumab, and Capecitabine for HER2-Positive Metastatic Breast Cancer.

Background: Patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer who have disease progression after therapy with multiple HER2-targeted agents have limited treatment options. Tucatinib is an investigational, oral, highly selective inhibitor of the HER2 tyrosine kinase.

Methods: We randomly assigned patients with HER2-positive metastatic breast cancer previously treated with trastuzumab, pertuzumab, and trastuzumab emtansine, who had or did not have brain metastases, to receive either tucatinib or placebo, in combination with trastuzumab and capecitabine.
