Prolonged treatment of HER2 positive breast cancer cells with tyrosine kinase inhibitors (TKIs) leads to the emergence of acquired resistance. However, the effects of continuous TKI exposure on cell fate, and the steps leading to the acquisition of a resistant phenotype are poorly understood. To explore this, we exposed five HER2 positive cells lines to HER2 targeted therapies for periods of up to 4 weeks and examined senescence associated β-galactosidase (SA-β-gal) activity together with additional markers of senescence.

Scale-up of antiretroviral therapy (ART) for people living with HIV requires differentiated models of ART delivery to improve access and contribute to achieving viral suppression for 95% of people on ART. We examined barriers and enablers in South Africa via semistructured interviews with 33 respondents (program implementers, nurses, and other health care providers) from 11 organizations. The interviews were recorded, transcribed, and analyzed for emerging themes using NVivo 11 software.

Coinfection of host populations alters pathogen prevalence, host mortality, and pathogen evolution. Because pathogens compete for limiting resources, whether multiple pathogens can coexist in a host population can depend on their within-host interactions, which, in turn, can depend on the order in which pathogens infect hosts (within-host priority effects). However, the consequences of within-host priority effects for pathogen coexistence have not been tested.

Ocean metaproteomics is an emerging field enabling discoveries about marine microbial communities and their impact on global biogeochemical processes. Recent ocean metaproteomic studies have provided insight into microbial nutrient transport, colimitation of carbon fixation, the metabolism of microbial biofilms, and dynamics of carbon flux in marine ecosystems. Future methodological developments could provide new capabilities such as characterizing long-term ecosystem changes, biogeochemical reaction rates, and in situ stoichiometries.

Background: Oral pre-exposure prophylaxis (PrEP) is a highly effective option for HIV prevention. To realize the full benefit of PrEP at the population level, uptake must reach those at the greatest risk of HIV acquisition. Guidance published by Centers for Disease Control and Prevention (CDC) suggests that the number of individuals with indications for PrEP is 1.

Background: Resilience is a contextual phenomenon where a complex and dynamic interplay exists between individual, environmental, and socio-cultural factors. With growing interest in enhancing resilience in physicians, given their high risk for experiencing prolonged or intense stress, effective strategies are necessary to improve resilience and reduce negative outcomes including burnout. The objective of this review was to identify effective interventions to improve resilience in physicians who have completed training, working in any setting.

Objective: This study examined a hypothesized pathway by which interoceptive dysfunction accounted for associations between personality features (harm avoidance, self-directedness, and perfectionism) and anorexia nervosa (AN) severity (indicated by drive for thinness, eating disorder-related preoccupations and rituals, and body mass index).

Method: The study sample (n = 270, mean age = 28.47, 95.

Purpose: The purpose of this study was to evaluate the combined measurement of serum CEA, TPA, and CA 15-3, using an individual reference limit (IRL), for predicting distant metastases in asymptomatic women following a diagnosis of primary breast cancer.

Methods: A total of 231 patients were followed up for a mean of 5.5±1.

Background: Vitamin D has been linked with improved survival after breast cancer diagnosis but little is known about prescribing rates. This study investigates trends in vitamin D supplement use in both a general female and breast cancer population.

Methods: Women with a breast cancer diagnosis were identified from the National Cancer Registry of Ireland (n = 19870).

Background: Clinical audit may improve practice in cancer service provision. The UK National Lung Cancer Audit (NLCA) collects data for all new cases of thoracic cancers.

Aim: To collect similar data for our Victorian patients from six hospitals within the Victorian Comprehensive Cancer Centre and associated Western and Central Melbourne Integrated Cancer Service.

: Effective immunotherapy of stromal-rich tumors requires simultaneous targeting of cancer cells and immunosuppressive elements of the microenvironment. Here, we modified the oncolytic group B adenovirus enadenotucirev to express a stroma-targeted bispecific T-cell engager (BiTE). This BiTE bound fibroblast activation protein on cancer-associated fibroblasts (CAF) and CD3ε on T cells, leading to potent T-cell activation and fibroblast death.

The aim was to investigate mechanical and functional failure of diffuse axonal injury (DAI) in nerve bundles following frontal head impacts, by finite element simulations. Anatomical changes following traumatic brain injury are simulated at the macroscale by using a 3D head model. Frontal head impacts at speeds of 2.

Knowledge-based planning (KBP) can be used to improve plan quality, planning speed, and reduce the inter-patient plan variability. KPB may also identify and reduce systematic variations in VMAT plans, something very important in multi-institutional clinical trials. Training of a KBP library is a complex and difficult process, and models must be validated prior to their clinical use.

Purpose: This study examined prevalence of self-injurious thoughts and behaviors (SITBs) in transgender individuals with eating disorders, as compared to cisgender individuals with eating disorders and transgender individuals without eating disorders.

Methods: Data were analyzed from 365,749 individuals (median age 21 years, 71.8% White/Caucasian, 34.
