Acute Exercise Increases NK Cell Mitochondrial Respiration and Cytotoxicity against Triple-Negative Breast Cancer Cells under Hypoxic Conditions.

Purpose: Triple-negative breast cancer (TNBC) is an aggressive, highly metastatic malignancy with high recurrence rates. Hypoxia is a hallmark of the TNBC tumor microenvironment, which promotes tumor growth while impairing natural killer (NK) cell cytotoxic functions. Although acute exercise improves NK cell function under normoxic conditions, the effect of exercise on NK cell cytotoxic functions under hypoxic conditions mimicking O 2 tensions observed in solid tumors is unknown.

Remote Spectral Light Sensing in the Home Environment: Further Development of the TWLITE Study Concept.

Aging is a significant contributor to changes in sleep patterns, which has compounding consequences on cognitive health. A modifiable factor contributing to poor sleep is inadequate and/or mistimed light exposure. However, methods to reliably and continuously collect light levels long-term in the home, a necessity for informing clinical guidance, are not well established.

An International Systematic Review Concerning the Effect of Social Media Exposure on Public Compliance with Infection Prevention and Control Measures During the COVID-19 Pandemic.

Background: Effective health communication is crucial for achieving positive population health outcomes. This is important for infection prevention and control (IPC), which relies on widespread public compliance to be effective. Whilst social media (SM) platforms disseminate health information, there is conflicting evidence to suggest their influence on compliance with public health guidelines.

Aging Veterans and a Silver Lining of Service.

The objective of this study was to explore aging veteran's military experiences, including serving in conflicts or wars and their military-related health issues, with a focus on the impacts of their experiences on the aging process. A cohort of 48 Pacific Northwest, primarily rural, Vietnam-era veterans responded to a survey questionnaire emailed in 2021. The main survey question addressed in this article is, "Do you believe that your military experience has made aging more difficult?" Fifty percent of this cohort served in a conflict or war, mostly in Vietnam, and 68% reported having military-related health issues.

Postmortem 7T MRI for guided histopathology and evaluation of cerebrovascular disease.

Postmortem (PM) magnetic resonance imaging (MRI) can serve as a bridge between in vivo imaging and histology by connecting MRI observed macrostructural findings to histological staining and microstructural changes. Data were acquired from 20 formalin-fixed brains including T2, T1, PD, and T2*-weighted images of left hemispheres and 6-mm-thick coronal slices. Tissue slices were bisected, aligned to MR images and used to guide histological sampling.

Mood and activity changes during the COVID-19 pandemic in rural and urban Veterans and their cohabitants.

Objectives: We aimed to examine the impact of COVID-19 pandemic-related stay-at-home orders on weekly reports of mood and activity before and during COVID-19 in a sample of older Veterans and their cohabitants.

Methods: Urban and rural Veterans and their cohabitants living in the Pacific Northwest ≥62 years old were enrolled as part of the Collaborative Aging Research Using Technology initiative (n = 100, age = 71.2 ± 6.

An Arts-Based Workshop Using Scalp Tattoos to Connect Students with Cancer Patients' Experiences of Chemotherapy and Hair Loss.

Problem: Students eager to enter the medical field must develop perspective-taking skills that enhance their ability to connect with patients. Toward this goal, the authors developed a pilot workshop for undergraduate students that included an art activity during which they collaborated to design scalp tattoos to symbolize cancer patients' experiences with chemotherapy and hair loss.

Approach: A 90-minute, arts-based workshop was held in April 2019.

Prolonged Physical Inactivity in Older Adult Couples: A Dyadic Analysis Using Actigraphy.

Background And Objectives: Many older adults remain inactive despite the known positive health implications of physical activity (improved mood, reduced mortality risk). Physical inactivity is an interdependent phenomenon in couples, but most research examines physical inactivity at the individual level. We estimated the average amount of prolonged physical inactivity for older adult couples and, using dyadic analysis, identified physical and mental health determinants thereof.

The Collaborative Aging Research Using Technology Initiative: An Open, Sharable, Technology-Agnostic Platform for the Research Community.

Introduction: Future digital health research hinges on methodologies to conduct remote clinical assessments and in-home monitoring. The Collaborative Aging Research Using Technology (CART) initiative was introduced to establish a digital technology research platform that could widely assess activity in the homes of diverse cohorts of older adults and detect meaningful change longitudinally. This paper reports on the built end-to-end design of the CART platform, its functionality, and the resulting research capabilities.

Oxidized Products of Omega-6 and Omega-3 Long Chain Fatty Acids Are Associated with Increased White Matter Hyperintensity and Poorer Executive Function Performance in a Cohort of Cognitively Normal Hypertensive Older Adults.

Background: Cerebrovascular disease is a common cause of dementia in older adults, and potentially preventable with early intervention. Oxylipins are produced from the oxidation of long-chain polyunsaturated fatty acids (PUFA) possessing potent vascular effects. Oxylipins generated from the cytochrome P450 pathway are enzymatically converted to diols by soluble epoxide hydrolase (sEH); sEH products have been associated with small vessel ischemic disease.

Neuropsychiatry of sport-related concussion.

Changes in mood, emotions, and behavior are common components of the acute clinical picture of sport-related concussion (SRC). Common concussion symptom inventories such as the Sport Concussion Assessment Tool-5 (SCAT5) contain a large number of questions that assess these neuropsychiatric domains. In fact, of 22 items assessed by the SCAT5, arguably only five of the items do not overlap with symptoms assessed by standard measures of anxiety and depression, suggesting that concussion is best viewed as a neuropsychiatric syndrome.

Role of advanced neuroimaging, fluid biomarkers and genetic testing in the assessment of sport-related concussion: a systematic review.

Objective: To conduct a systematic review of published literature on advanced neuroimaging, fluid biomarkers and genetic testing in the assessment of sport-related concussion (SRC).

Data Sources: Computerised searches of Medline, PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Scopus and Cochrane Library from 1 January 2000 to 31 December 2016 were done. There were 3222 articles identified.

Methylphenidate and Memory and Attention Adaptation Training for Persistent Cognitive Symptoms after Traumatic Brain Injury: A Randomized, Placebo-Controlled Trial.

The purpose of this multicenter, prospective, randomized, placebo-controlled study was to evaluate and compare the efficacy of two cognitive rehabilitation interventions (Memory and Attention Adaptation Training (MAAT) and Attention Builders Training (ABT)), with and without pharmacological enhancement (ie, with methylphenidate (MPH) or placebo), for treating persistent cognitive problems after traumatic brain injury (TBI). Adults with a history of TBI at least 4 months before study enrollment with either objective cognitive deficits or subjective cognitive complaints were randomized to receive MPH or placebo and MAAT or ABT, yielding four treatment combinations: MAAT/MPH (N=17), ABT/MPH (N=19), MAAT/placebo (N=17), and ABT/placebo (N=18). Assessments were conducted pre-treatment (baseline) and after 6 weeks of treatment (post treatment).

Local wellness policy strength and perceived implementation of school nutrition standards across three states.

Background: Congress sought to address escalating rates of childhood obesity by mandating local wellness policies (LWP) (Child Nutrition and WIC Reauthorization Act of 2004). Previous research has examined LWP content and quality; however, data relative to LWP implementation is limited, and none has examined the relationship between LWP quality and implementation. The purpose of this study was to examine the influence of LWP strength on perceived implementation of LWP components.

Characterisation of the ester-substituted products of the reaction of p-t-butyl calix[4]arene and ethyl bromoacetate using LC-UV-MS and LC-DAD.

A series of derivatisation reactions between p-t-butyl calix[4]arene and ethyl bromoacetate were carried out in order to prepare 1,3 diester substituted calix[4]arene. Mass spectral data, obtained from direct injection of samples, indicated that the reactions were rich in the desired product. Since the ultra violet (UV) spectra of the desired product and possible impurities are very similar, liquid chromatography (LC) chromatographic data seemed to corroborate these results.

Rapid and sensitive liquid chromatography-tandem mass spectrometry for the quantitation of epirubicin and identification of metabolites in biological samples.

A highly sensitive and selective liquid chromatography-mass spectrometry (LC-MS) method has been developed for the determination of epirubicin in serum and cell specimens using daunorubicin as an internal standard. Using atmospheric pressure chemical ionisation (APCI), the epirubicin metabolites were readily distinguishable by their fragmentation pattern in the mass spectrometer. Selected reaction monitoring (SRM) mode was employed for quantitation of epirubicin and the metabolites.
