Herpesvirus Antibodies Are Correlated With Greater Expression of p16 in the T Cells of Humans.

Background: There is an increasing awareness that aging of the immune system, or immunosenescence, is a key biological process underlying many of the hallmark diseases of aging and age-related decline broadly. While immunosenescence can be in part due to normal age-related changes in the immune system, emerging evidence posits that viral infections may be biological stressors of the immune system that accelerate the pace of immunosenescence.

Methods: We used a convenience sample of 42 individuals aged 65 years and older to examine correlations between antiviral immunoglobulin G (IgG) levels for 4 human herpesviruses (cytomegalovirus [CMV], herpes simplex virus [types 1 and 2], and Epstein-Barr virus) and multiple indicators of T-cell immunosenescence.

Frailty and rheumatic diseases: evidence to date and lessons learned.

Frailty represents a dynamic multisystem state of reduced physiological reserve that increases vulnerability to adverse health outcomes. Frailty occurs prematurely in adults with immune-mediated rheumatic diseases and is emerging as an important risk factor for adverse outcomes in these conditions. In this Series paper, we present a conceptual overview of frailty and its prevalence among patients with immune-mediated rheumatic diseases.

Cook and Move for Your Life, an eHealth intervention for women with breast cancer.

We tested the feasibility and preliminary efficacy of an online diet and physical activity program for women with early-stage breast cancer who had completed surgery, chemotherapy, and radiation therapy (ongoing endocrine therapy allowed). Participants with low fruit and vegetable (F/V) consumption and/or low moderate-to-vigorous physical activity (MVPA) levels were randomized to one of two doses - low (one Zoom group session) or high (12 Zoom group sessions) - of an online lifestyle program with the goal of improving F/V intake and MVPA. All participants received eHealth communications (text messages, study website access), a Fitbit, and a WiFi-enabled scale.

Prevalence and Factors Associated with De-escalation of Anti-TNFs in Older Adults with Rheumatoid Arthritis: A Medicare Claims-Based Observational Study.

Objective: The aim was to evaluate prevalence and factors associated with anti-tumor necrosis factor (anti-TNF) de-escalation in older adults with rheumatoid arthritis (RA).

Methods: We identified adults ≥ 66 years of age with RA on anti-TNF therapy within 6 months after RA diagnosis with at least 6-7 months duration of use (proxy for stable use), using 20% Medicare data from 2008-2017. Patient demographic and clinical characteristics, including concomitant use of glucocorticoid (GC), were collected.

Exploring COVID-19 vaccine uptake and hesitancy among vulnerable populations in inner city Vancouver, Canada: Insights into characteristics and clinical outcomes.

The COVID-19 pandemic is having a profound impact on the health, social and economic well-being of people in Canada and around the world. To address vaccine disparity among vulnerable populations facing social-structural challenges, it is crucial to provide evidence-based information on the importance of completion of the recommended vaccination schedule. In this study, we investigated vaccination rates and variables as facilitators or barriers to COVID-19 vaccination among vulnerable populations living in Vancouver's inner-city residents.

GRAND PLAN: Safety and Efficacy of Glecaprevir/Pibrentasvir for the Treatment of Hepatitis C Virus Infection Among People Initially Disengaged From Health Care Who Use Drugs-A Systematic Multidisciplinary Approach.

Background: GRAND PLAN is a prospective, open-label, phase 4 study. Based at a single center and with a single arm, GRAND PLAN evaluated the safety and efficacy of an 8-week course of glecaprevir/pibrentasvir (G/P) among active drug users with hepatitis C virus (HCV) infection in a population enriched for factors that may reduce treatment uptake and success, such as disengagement from health care and unstable housing.

Methods: Participants were ≥19 years old and actively using drugs and were confirmed viremic, noncirrhotic, and HCV treatment naive.

Race, Gene Expression Signatures, and Clinical Outcomes of Patients With High-Risk Early Breast Cancer.

Importance: There has been little consideration of genomic risk of recurrence by breast cancer subtype despite evidence of racial disparities in breast cancer outcomes.

Objective: To evaluate associations between clinical trial end points, namely pathologic complete response (pCR) and distant recurrence-free survival (DRFS), and race and examine whether gene expression signatures are associated with outcomes by race.

Design, Setting, And Participants: This retrospective cohort study used data from the Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging and Molecular Analysis 2 (I-SPY 2) multicenter clinical trial of neoadjuvant chemotherapy with novel agents and combinations for patients with previously untreated stage II/III breast cancer.

Initiation of Disease-Modifying Antirheumatic Drugs in Older Medicare Beneficiaries With New Diagnosis of Late-Onset Rheumatoid Arthritis.

Objective: Older adults with rheumatoid arthritis (RA) account for up to one-third of the RA population and are less likely to receive optimal treatment. For the subgroup of older adults with late-onset RA (LORA), who experience more symptomatic and progressive disease, suboptimal treatment could be more consequential than the general population who age with RA. We evaluated use of disease-modifying antirheumatic drugs (DMARDs) in older adults with a new diagnosis of LORA.

Racial disparities in the screening mammography continuum within a heterogeneous health care system.

Background: Decreased mammography drives breast cancer disparities. Black women have lower rates of mammography completion than White women, and this contributes to disparities in outcomes. Points of disparity along the continuum for screening mammography remain underresearched.

The effects of therapeutic virtual reality experience to promote mental well-being in older people living with physical disabilities in long-term care facilities.

Background: Mental well-being is poor in long-term care facilities (LTCF) residents. Physical disabilities, impaired social engagement, and environmental stress are also common in LTCF which exacerbate the decline of the mental well-being of older people living in LTCF. Protective elements, including nature-based, reminiscence, outdoor, and group activities, are known to be effective to promote the mental well-being of older people living in LTCF.

Safety and efficacy of HSP90 inhibitor ganetespib for neoadjuvant treatment of stage II/III breast cancer.

HSP90 inhibitors destabilize oncoproteins associated with cell cycle, angiogenesis, RAS-MAPK activity, histone modification, kinases and growth factors. We evaluated the HSP90-inhibitor ganetespib in combination with standard chemotherapy in patients with high-risk early-stage breast cancer. I-SPY2 is a multicenter, phase II adaptively randomized neoadjuvant (NAC) clinical trial enrolling patients with stage II-III breast cancer with tumors 2.

A digital health intervention to improve nutrition and physical activity in breast cancer survivors: Rationale and design of the Cook and Move for Your Life pilot and feasibility randomized controlled trial.

Background: The design of a randomized pilot trial evaluating the feasibility of two doses of a digital health intervention promoting changes in nutrition and physical activity in breast cancer (BC) survivors is described.

Methods: Eligible women were adults with history of early-stage breast cancer and > 60 days post-treatment, consumed <5 servings/day of fruits/vegetables and/or engaged in <150 min/week of aerobic moderate-to-vigorous physical activity, and had internet access. Participants were randomized to 6 months of either a "low" (1 session) or "high" (12 sessions) dose digital health intervention.

Genetic Testing Among Patients with High-Risk Breast, Ovarian, Pancreatic, and Prostate Cancers.

Background: The National Comprehensive Cancer Network recommends genetic testing in patients with potentially hereditary breast, ovarian, pancreatic, and prostate cancers (HBOPP). Knowledge of genetic mutations impacts decisions about screening and treatment.

Methods: A retrospective cohort study of 28,586 HBOPP patients diagnosed from 2013 to 2019 was conducted using a linked administrative-cancer database in the Seattle-Puget Sound SEER area.

Chronic Oxidative Stress as a Marker of Long-term Radiation-Induced Cardiovascular Outcomes in Breast Cancer.

While biomarkers have been proposed to identify individuals at risk for radiation-induced cardiovascular disease (RICVD), little is known about long-term associations with cardiac events. We examined associations of biomarkers of oxidative stress (myeloperoxidase, growth differentiation factor-15, 8-hydroxy-2'-deoxyguanosine [8-OH-dG], placental growth factor), cardiac injury (troponin I, cystatin-C), inflammation (interleukin-6, C-reactive protein), and myocardial fibrosis (transforming growth factor-ß) with long-term RICVD in breast cancer (BC) survivors. We conducted a nested case-control study within the Women's Health Initiative of postmenopausal women with incident BC stages I-III, who received radiation and had pre- and post-BC diagnosis serum samples.

Background: Conventionally fractionated whole-pelvic nodal radiotherapy (WPRT) improves clinical outcome compared to prostate-only RT in high-risk prostate cancer (HR-PC). MR-guided stereotactic body radiotherapy (MRgSBRT) with concomitant WPRT represents a novel radiotherapy (RT) paradigm for HR-PC, potentially improving online image guidance and clinical outcomes. This study aims to report the preliminary clinical experiences and treatment outcome of 1.

Antibiogram data from private hospitals in Hong Kong: 6-year retrospective study.

Introduction: The surveillance of antibiotic resistance is critical for the establishment of effective control strategies. The antibiotic resistance situations in private hospitals in Hong Kong have not been systematically described. The objective of the study was to analyse antibiogram data from private hospitals and describe the temporal trends of non-susceptibility percentages in this setting.

Rapid antigen test during a COVID-19 outbreak in a private hospital in Hong Kong.

Introduction: In response to two nosocomial clusters of coronavirus disease 2019 (COVID-19) in our hospital, we adopted a series of strict infection control measures, including regular rapid antigen test (RAT) screening for high-risk patients, visitors, and healthcare workers. We evaluated the diagnostic performance of a locally developed RAT, the INDICAID COVID-19 Rapid Antigen Test (Phase Scientific, Hong Kong), using respiratory samples from both symptomatic and asymptomatic individuals.

Methods: Real-time reverse-transcription polymerase chain reaction (rRT-PCR)-confirmed deep throat saliva (DTS) and pooled nasopharyngeal swab and throat swab (NPS/TS) samples collected from 1 November to 30 November 2020 were tested by INDICAID.

Provider Specialty and the Use of Disease-Modifying Antirheumatic Drugs for Rheumatoid Arthritis Among Older Adults in the 2005-2016 National Ambulatory Medical Care Survey.

Objective: We compared disease-modifying antirheumatic drug (DMARD) use for older adults with rheumatoid arthritis (RA)-related ambulatory visits from rheumatologists and primary care providers (PCPs).

Methods: In this study of national sample office visits, we characterized ambulatory visits by older adults 65 years of age or older seen by rheumatologists or PCPs for diagnosis of RA using the 2005-2016 National Ambulatory Medical Care Survey. We analyzed patterns and trends of DMARD use using descriptive statistics and multivariable analyses by provider specialty.

Epigenetic imprinting alterations as effective diagnostic biomarkers for early-stage lung cancer and small pulmonary nodules.

Background: Early lung cancer detection remains a clinical challenge for standard diagnostic biopsies due to insufficient tumor morphological evidence. As epigenetic alterations precede morphological changes, expression alterations of certain imprinted genes could serve as actionable diagnostic biomarkers for malignant lung lesions.

Results: Using the previously established quantitative chromogenic imprinted gene in situ hybridization (QCIGISH) method, elevated aberrant allelic expression of imprinted genes GNAS, GRB10, SNRPN and HM13 was observed in lung cancers over benign lesions and normal controls, which were pathologically confirmed among histologically stained normal, paracancerous and malignant tissue sections.
