Emc1 is essential for vision and zebrafish photoreceptor outer segment morphogenesis.

Inherited retinal diseases (IRDs) are a rare group of eye disorders characterized by progressive dysfunction and degeneration of retinal cells. In this study, we characterized the raifteirí (raf) zebrafish, a novel model of inherited blindness, identified through an unbiased ENU mutagenesis screen. A mutation in the largest subunit of the endoplasmic reticulum membrane protein complex, emc1 was subsequently identified as the causative raf mutation. We sought to elucidate the cellular and molecular phenotypes in the emc1-/- knockout model and explore the association of emc1 with retinal degeneration. Visual behavior and retinal electrophysiology assays demonstrated that emc1-/- mutants had severe visual impairments. Retinal histology and morphometric analysis revealed extensive abnormalities, including thinning of the photoreceptor layer, in addition to large gaps surrounding the lens. Notably, photoreceptor outer segments were drastically smaller, outer segment protein expression was altered and hyaloid vasculature development was disrupted. Transcriptomic profiling identified cone and rod-specific phototransduction genes significantly downregulated by loss of emc1. These data shed light on why emc1 is a causative gene in inherited retinal disease and how outer segment morphogenesis is regulated.

The evaluation of an osteoporosis medication management service in community pharmacy, a cohort study.

Background: Effective treatment of osteoporosis is hindered by poor adherence and lack of persistence with medical therapy. Interventions can be designed to elicit and address patients' concerns about side effects and promote self-management. Objective(s): The aim was to develop and evaluate the impact of a community pharmacy-based medication management intervention on patients' adherence to osteoporosis medicines using both objective and subjective measures of adherence. Secondary aims were to report the proportion of patients that had been referred to their General Practitioner (GP) for assistance with osteoporosis management, and to measure patients' experiences with the service. Methods: This study used a cohort design. Community pharmacy dispensing data were obtained as an objective measure of adherence. Self-reported beliefs about medicines (Beliefs about Medicines Questionnaire) and self-reported adherence (Medication Adherence Reporting Scale 5) were also collected. Data were collected and compared between baseline, 4 weeks after intervention, and endpoint (approximately a year after intervention). Analysis of correlations between measures was also conducted. GP referral percentage and perceived service quality scale (pSQS-SF6) was obtained. Results: Pharmacists and support staff from 26 Australian community pharmacies were recruited and trained to implement the service, and 107 patients were recruited. Of these, 71 were available for follow-up interviews by research team at 4 weeks, and 54 at the endpoint. No changes were found in pre-post analysis for the objective or self-reported measures of adherence. Patients' concerns about osteoporosis medicines were lower at 4 weeks and at the study endpoint compared to baseline. Uptake of pharmacists' referrals to patients' GPs was 48.1% by 4 weeks. Patient experience was rated highly (median pSQS-SF6 = 6.5/7). Conclusions: This study demonstrates the potential of community pharmacy interventions designed to optimize medication adherence by eliciting patients' thoughts and feelings about using osteoporosis medicines and addressing them using motivational interview techniques.

Pre-workout Dietary Nitrate Magnifies Training-induced Benefits to Physical Function in Late Postmenopausal Women: A Randomized Pilot Study.

To inform endpoints for future work, we explored the utility of pre-workout (i.e., an acute dose before training) beetroot juice (BRJ) combined with exercise (BRJ+EX) to augment indices of physical function in postmenopausal women compared to exercise only (EX). A two-arm pilot was employed to compare 24 postmenopausal women following an 8-wk, circuit-based exercise intervention. Participants were randomized to BRJ+EX (n = 12) or EX (n = 12). BRJ+EX participants consumed 140-mL of BRJ 120-180 min (only) before training for 7-wk, then discontinued during the final week to mitigate carryover effects. Physical function indices were: 6-min walk test (6MWT), estimated V̇O2peak, heart rate recovery (HRR), and maximal knee extensor power (Pmax). A treadmill task was used to measure V̇O2 on-kinetics wherein mean response time (MRT) coincided with the duration to reach 63% of steady-state V̇O2. Results showed greater changes (Δ) among BRJ+EX participants for 6MWT distance (40 ± 23 m vs. 8 ± 25 m; p = 0.003, d = 1.35), ΔV̇O2peak (1.5 ± 0.9 mLꞏkg-1ꞏmin-1 vs. 0.3 ± 1.0 mLꞏkg-1ꞏmin-1; p = 0.008, d = 1.20), and ΔHRR (-10 ± 6 bpm vs. -1 ± 9 bpm; p = 0.017, d = 1.05). Large and medium effect sizes favoring BRJ+EX were detected for ΔPmax (p = 0.07, d = 0.83) and ΔMRT (p = 0.257, d = 0.50), respectively. In postmenopausal women, BRJ+EX appears to magnify some adaptive benefits to physical function including aerobic capacity and recovery beyond that of training without BRJ. Investigation into contributing mechanisms is needed.

Health outcomes following provision of Home Medicines Reviews for older people receiving aged care services at home.

BACKGROUND: The impact of Home Medicines Reviews (HMRs) on long-term health outcomes among individuals receiving long-term in-home aged care services is unknown. OBJECTIVES: To examine associations between HMR provision and hospitalization, long-term care facility (LTCF) entry and mortality among older people receiving long-term in-home aged care services. METHODS: This retrospective cohort study included individuals aged 65-105 years from three Australian states who accessed in-home aged care services between 2013 and 2017. Using propensity score matching, HMR recipients (n = 1530) were matched to individuals who did not receive an HMR (n = 1530). Associations between HMR provision and outcomes were estimated using multivariable regression models. RESULTS: Over a median of 414 days (interquartile range 217-650) of follow-up, HMR provision was not associated with hospitalizations for unplanned events (subdistribution hazard ratio (sHR) 1.04, 95%CI 0.96-1.14), falls-related hospitalizations (sHR 0.97, 95%CI 0.83-1.13), LTCF entry (sHR 0.97, 95%CI 0.83-1.13), or all-cause mortality (adjusted HR 0.86, 95%CI 0.72-1.01). CONCLUSIONS: In a cohort of older people receiving long-term in-home aged care services, no differences in unplanned hospitalizations, falls, LTCF entry or mortality were observed those with HMRs compared to those that did not receive an HMR.

Neuroimaging and Clinical Findings in Healthy Middle-Aged Adults With Mild Traumatic Brain Injury in the PREVENT Dementia Study.

Importance: Traumatic brain injuries (TBI) represent an important, potentially modifiable risk factor for dementia. Despite frequently observed vascular imaging changes in individuals with TBI, the relationships between TBI-associated changes in brain imaging and clinical outcomes have largely been overlooked in community cases of TBI. Objective: To assess whether TBI are associated with and interact with midlife changes in neuroimaging and clinical features in otherwise healthy individuals. Design, Setting, and Participants: This cross-sectional analysis used baseline data from the PREVENT Dementia program collected across 5 sites in the UK and Ireland between 2014 and 2020. Eligible participants were cognitively healthy midlife adults aged between 40 and 59 years. Data were analyzed between January 2023 and April 2024. Exposure: Lifetime TBI history was assessed using the Brain Injury Screening Questionnaire. Main Outcomes and Measures: Cerebral microbleeds and other markers of cerebral small vessel disease (white matter hyperintensities [WMH], lacunes, perivascular spaces) were assessed on 3T magnetic resonance imaging. Clinical measures were cognition, sleep, depression, gait, and cardiovascular disease (CVD) risk, assessed using Computerized Assessment of Information Processing (COGNITO), Pittsburgh Sleep Quality Index, Center for Epidemiologic Studies Depression Scale, clinical interviews, and the Framingham Risk Score, respectively. Results: Of 617 participants (median [IQR] age, 52 [47-56] years; 380 female [61.6%]), 223 (36.1%) had a history of TBI. TBI was associated with higher microbleed count (ß = 0.10; 95% CI, 0.01-0.18; P = .03), with a dose-response association observed with increasing number of TBI events (ß = 0.05; 95% CI, 0.01-0.09; P = .03). Conversely, TBI was not associated with other measures of small vessel disease, including WMH. Furthermore, TBI moderated microbleed associations with vascular risk factors and clinical outcomes, such that associations were present only in the absence of TBI. Importantly, observations held when analyses were restricted to individuals reporting only mild TBI. Conclusions and Relevance: In this cross-sectional study of healthy middle-aged adults, detectable changes in brain imaging and clinical features were associated with remote, even mild, TBI in the general population. The potential contribution of vascular injury to TBI-related neurodegeneration presents promising avenues to identify potential targets, with findings highlighting the need to reduce TBI through early intervention and prevention in both clinical care and policymaking.

Development and validation of measures of pharmacists' acceptability and willingness to screen for perinatal depression.

BACKGROUND: While pharmacists' roles in mental healthcare are expanding, research exploring pharmacists' acceptability and willingness to provide mental health services is limited. This study developed and validated theory-driven measures of pharmacists' acceptability and willingness to screen for perinatal depression in community pharmacy settings. MATERIALS/METHODS: Items were developed using published literature and the Theoretical Framework of Acceptability (TFA), then content validated using consensus methods with experts who completed the content validity index (CVI). The revised items were disseminated to pharmacists in Australia. Responses were analysed descriptively. Exploratory factor analyses (EFA) were used to explore the factorial structure and generate scales. Multivariate regression analysis was conducted to explore predictors of willingness. RESULTS: A 58-item questionnaire was developed, encompassing the 7 domains of the TFA and an eighth domain (willingness). The average CVI was 0.92, domain range (0.88-0.96). The universal CVI was 56/58. Expert feedback informed item revision, creation and deletion. Pharmacists' responses (n = 157) to the final 42-item questionnaire indicated overall acceptance and willingness to conduct PND screening. However, perceived knowledge was lacking. The EFA resulted a two-factor solution (1 = acceptance; 2 = self-efficacy). The measurement scales created had good internal consistency. In multivariate regression analysis, 'Acceptance' (Beta = 0.949 (0.760-1.103)) and 'Self-Efficacy' (Beta = 0.107 (0.036-0.174)) were significant predictors of 'Willingness' and the model predicted 77 % of the variation in 'Willingness'. CONCLUSIONS: Psychometrically-sound measures of pharmacists' acceptability and willingness to screen for PND have been developed with stakeholder input. The questionnaire can be used for standardised measurement of these constructs across studies.

Ribosome-Associated Vesicles promote activity-dependent local translation.

Local protein synthesis in axons and dendrites underpins synaptic plasticity. However, the composition of the protein synthesis machinery in distal neuronal processes and the mechanisms for its activity-driven deployment to local translation sites remain unclear. Here, we employed cryo-electron tomography, volume electron microscopy, and live-cell imaging to identify Ribosome-Associated Vesicles (RAVs) as a dynamic platform for moving ribosomes to distal processes. Stimulation via chemically-induced long-term potentiation causes RAV accumulation in distal sites to drive local translation. We also demonstrate activity-driven changes in RAV generation and dynamics in vivo, identifying tubular ER shaping proteins in RAV biogenesis. Together, our work identifies a mechanism for ribosomal delivery to distal sites in neurons to promote activity-dependent local translation.

Dietary NO3- does not enhance endothelial dependent cutaneous vascular conductance in older women.

Prior work has yet to determine whether the reduction of dietary nitrate (NO3-) to NO, via the enterosalivary pathway, may modify cutaneous vascular conductance (CVC) responses to local heating in older women. Changes occurring with the transition to menopause related to hormonal flux, increased adiposity, and/or decreased physical activity may further compound the negative influence of aging on nitric oxide (NO)-dependent CVC. Herein, we characterized changes in NO-dependent CVC following acute ingestion of 140 mL of NO3--rich beetroot juice in 24 older women (age: 65 ± 5 y, BMI: 31.2 ± 3.7 kg/m2). Red blood cell (RBC) flux was measured continuously via laser-Doppler flowmetry on the dorsal aspect of the forearm during local skin heating to 39 °C/44 °C before and 3 h after NO3- ingestion. NO-dependent changes in CVC were calculated as RBC flux/mean arterial blood pressure at 39 °C and normalized as a proportion of maximal CVC at 44 °C (%CVCmax). Changes (Δ) in fractional exhaled NO (FeNO) following NO3- ingestion were used an index of NO bioavailability. Despite increased FeNO (+81 ± 70 %, P < 0.001), %CVCmax at 39 °C was reduced (-16 ± 10 %, P < 0.001) following NO3- ingestion. A greater reduction in %CVCmax was weakly to moderately associated with higher body fat% (r = 0.45 [0.05-0.72], P = 0.029), central adiposity% (r = 0.50 [0.13-0.75], P = 0.012), neutrophil% (r = 0.42 [0.02-0.70], P = 0.041), and higher neutrophil to lymphocyte ratio (r = 0.49 [0.11-0.75], P = 0.016). These findings demonstrate a single dose of dietary NO3- does not promote CVC responses to local heating in sedentary older women with overweight and obesity. Correlation with multiple biomarkers suggest systemic inflammation may be involved.

Role of Gut Microbe Composition in Psychosocial Symptom Response to Exercise Training in Breast Cancer Survivors (ROME) study: protocol for a randomised controlled trial.

INTRODUCTION: Breast cancer survivors have an increased risk for chronic fatigue and altered gut microbiota composition, both with negative health and quality of life affects. Exercise modestly improves fatigue and is linked to gut microbial diversity and production of beneficial metabolites. Studies suggest that gut microbiota composition is a potential mechanism underlying fatigue response to exercise. Randomised controlled trials testing the effects of exercise on the gut microbiome are limited and there is a scarcity of findings specific to breast cancer survivors. The objective of this study is to determine if fitness-related modifications to gut microbiota occur and, if so, mediate the effects of aerobic exercise on fatigue response. METHODS AND ANALYSIS: The research is a randomised controlled trial among breast cancer survivors aged 18-74 with fatigue. The primary aim is to determine the effects of aerobic exercise training compared with an attention control on gut microbiota composition. The secondary study aims are to test if exercise training (1) affects the gut microbiota composition directly and/or indirectly through inflammation (serum cytokines), autonomic nervous system (heart rate variability) or hypothalamic-pituitary-adrenal axis mediators (hair cortisol assays), and (2) effects on fatigue are direct and/or indirect through changes in the gut microbiota composition. All participants receive a standardised controlled diet. Assessments occur at baseline, 5 weeks, 10 weeks and 15 weeks (5 weeks post intervention completion). Faecal samples collect the gut microbiome and 16S gene sequencing will identify the microbiome. Fatigue is measured by a 13-item multidimensional fatigue scale. ETHICS AND DISSEMINATION: The University of Alabama at Birmingham Institutional Review Board (IRB) approved this study on 15 May 2019, UAB IRB#30000320. A Data and Safety Monitoring Board convenes annually or more often if indicated. Findings will be disseminated in peer-reviewed journals and conference presentations. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT04088708.

Osteoporosis screening in Australian community pharmacies: A mixed methods study.

ISSUES ADDRESSED: Osteoporosis and poor bone health impact a large proportion of the Australian population, but is drastically underdiagnosed and undertreated. Community pharmacies are a strategic location for osteoporosis screening services due to their accessibility and the demographic profile of customers. The aim of this study was to develop, implement and evaluate a community pharmacy health promotion service centred on encouraging consumers to complete an anonymous osteoporosis screening survey called Know Your Bones. METHODS: The implementation process was documented using the REAIM (reach, effectiveness, adoption, implementation, maintenance) framework. Uptake of the Know Your Bones screening tool was monitored anonymously with website traffic. Surveys and interviews were designed to capture consumer outcomes after screening. Semi-structured interviews were conducted with Australian community pharmacy stakeholders during design and implementation phases to explore their perspectives of the barriers and facilitators. RESULTS: The service was implemented in 27 community pharmacies. There were 448 visits to the screening website. Interviews were conducted with 41 stakeholders. There were a range of factors that appeared to influence implementation of the service. Perceived acceptability was critical, which depended on staff training, pharmacists' altruism, and remuneration. Staff relied heavily on their existing close relationships with consumers. No consumers completed non-anonymous surveys or agreed to participate in interviews post-screening. CONCLUSION: Using an implementation science approach, a community pharmacy osteoporosis screening service for the Australian context was designed and found to be acceptable to pharmacy staff and effective in reaching the target population. SO WHAT?: This low-cost and non-invasive health promotion has potential to sustainably increase national screening rates for osteoporosis.

Socioeconomic impact and sufficiency of government financial support during COVID-19 pandemic: A retrospective study.

This study examines the socioeconomic impact of the COVID-19 pandemic and the sufficiency of government support. Based on an online survey with 920 respondents, the cross-tabulation and binary logistic regression results show: firstly, in terms of loss of income, male respondents are more likely to have a loss of income as compared to female counterparts, and secondly, among different categories of employment status, the self-employed respondents are the most vulnerable group, given that more than 20 percent of them experienced loss of income due to the COVID-19 pandemic. Moreover, respondents working in small-and-medium enterprises (SMEs) and the informal sector are more likely to face loss of income as compared to respondents working in other sectors of employment. Likewise, respondents without tertiary education level are more likely to have a loss of income as compared to respondents with university certification. The baseline results highlight the insufficiency of government financial support programs based on the perspective of Malaysians from different demographic backgrounds. As a policy implication, the findings could guide the State in formulating the right policies for target groups who need more assistance than others in the community.

Engagement to collaboration ensures success.

Disruption to our daily business and functional lives is becoming more frequent, complex and costly. As leaders, what do we do with what we know, the support and tools we have, and our knowledge regarding the resources we need to acquire to navigate this disrupted world? One thing is clear: no one can do it alone. This is not a new concept - the ancient Greeks understood the power of the group. This paper argues that collaboration is the key to amplified knowledge, ability, energy, foresight and innovation, as there is obvious synergy when individuals, groups or organisations join together in a shared vision and with a dedicated purpose. This paper describes a process model developed by the Mid-Atlantic Center for Emergency Management & Public Safety to transform operational functions and spark quality engagement, the synergy of ideas and outcomes, and enhanced sustainability of purpose. This model uses a blend of new knowledge and experiences to build on collaboration models of the past, and has proven to be a success.

Understanding Patient Perspectives on the Use of Gamification and Incentives in mHealth Apps to Improve Medication Adherence: Qualitative Study.

BACKGROUND: Medication nonadherence remains a significant health and economic burden in many high-income countries. Emerging smartphone interventions have started to use features such as gamification and financial incentives with varying degrees of effectiveness on medication adherence and health outcomes. A more consistent approach to applying these features, informed by patient perspectives, may result in more predictable and beneficial results from this type of intervention. OBJECTIVE: This qualitative study aims to identify patient perspectives on the use of gamification and financial incentives in mobile health (mHealth) apps for medication adherence in Australian patients taking medication for chronic conditions. METHODS: A total of 19 participants were included in iterative semistructured web-based focus groups conducted between May and December 2022. The facilitator used exploratory prompts relating to mHealth apps, gamification, and financial incentives, along with concepts raised from previous focus groups. Transcriptions were independently coded to develop a set of themes. RESULTS: Three themes were identified: purpose-driven design, trust-based standards, and personal choice. All participants acknowledged gamification and financial incentives as potentially effective features in mHealth apps for medication adherence. However, they also indicated that the effectiveness heavily depended on implementation and execution. Major concerns relating to gamification and financial incentives were perceived trivialization and potential for medication abuse, respectively. CONCLUSIONS: The study's findings provide a foundation for developers seeking to apply these novel features in an app intervention for a general cohort of patients. However, the study highlights the need for standards for mHealth apps for medication adherence, with particular attention to the use of gamification and financial incentives. Future research with patients and stakeholders across the mHealth app ecosystem should be explored to formalize and validate a set of standards or framework.

Stakeholders' perspectives and experiences of the pharmacist's role in deprescribing in ambulatory care: A qualitative meta-synthesis.

BACKGROUND: Deprescribing is an effective strategy to manage polypharmacy and improve patient outcomes. The notion of a potential role for pharmacists in a multidisciplinary team approach to deprescribing has been identified in quantitative and qualitative literature. However, stakeholders' perceptions of this role, and factors that may impede or facilitate the pharmacist's involvement have not been elucidated. The application in ambulatory care also requires clarification. Understanding stakeholders' views is essential to optimise involvement of the pharmacist in deprescribing and improve practice. OBJECTIVES: First, to synthesize the perspectives and experiences of stakeholders (primary care providers, pharmacists, patients, and carers) regarding the role and involvement of the pharmacist in deprescribing in ambulatory care settings. Second, to identify barriers and strategies to enhancing pharmacist involvement in deprescribing. METHODS: A systematic search was conducted across CINAHL, Embase, Medline, and Scopus from database inception to April 2023 for qualitative studies in English exploring the pharmacist's role in deprescribing. Data were extracted for iterative and inductive development of themes. A meta-synthesis facilitated the identification of overarching themes. Qualitative secondary analysis enabled identification of barriers and facilitators to the pharmacist's involvement in deprescribing. RESULTS: From 285 articles identified, 9 studies were included which explored the views of general practitioners, specialist physicians, pharmacists, nurse practitioners, patients, carers, and general practice and clinic staff as stakeholders in deprescribing in ambulatory care. The meta-synthesis identified 4 over-arching themes: (1) therapeutic impetus and the status quo mentality, (2) role and responsibility, (3) multidisciplinary care, and (4) conflicting interests in pharmacy practice. Strategies to enhance pharmacists' involvement in deprescribing emerged from the data, and the pharmacist's role was strongly encouraged by stakeholders despite logistical and perceptual barriers identified. CONCLUSIONS: Incorporation of the strategies to enhance the pharmacist's involvement in deprescribing identified in this review is encouraged to optimise patient-centred care and improve practice.

Walking net V ˙ O2 rises with advancing age in older women: where to go from here?

PURPOSE: Walking net V ˙ O2 tends to increase with advancing age; however, factors contributing to this relationship have not been widely described. The implications of such findings could inform targeted strategies to promote independent mobility in older adults. Herein, we evaluated the relationship between net V ˙ O2 and age at two submaximal workloads while exploring potential moderators of this relationship. METHODS: Secondary analyses were performed on 35 older (65 ± 3 years) women who completed a battery of physical assessments including fixed-speed, non-graded and graded (+ 2.5%) treadmill walking with indirect calorimetry to determine net V ˙ O2. Maximal oxygen uptake ( V ˙ O2max), knee extensor maximal isometric voluntary contraction (MVC), peak rate of torque development (RTD), and plantar flexor range-of-motion (PFROM) were also measured. RESULTS: Bivariate correlations showed non-graded (r = 0.403, p = 0.017) and graded (r = 0.413, p = 0.014) net V ˙ O2 were positively related to age. Notably, these relationships strengthened after adjusting for V ˙ O2max. Regression modeling showed age, RTD:MVC ratio (composite of muscle performance), and PFROM together explained 49% and 34% of the variance in non-graded and graded net V ˙ O2, respectively. Further analyses suggested knee extensor MVC moderates the relationship between non-graded net V ˙ O2 and age, accounting for 9% of the variance [ΔR2 = 0.090, F (1,31) = 4.13, p = 0.05]. CONCLUSION: These data support the premise that, in older women, walking net V ˙ O2 rises with advancing age, and additionally, the RTD:MVC ratio and PFROM are independent correlates of non-graded net V ˙ O2. Exercise interventions with a high degree of training specificity including explosive, velocity-based elements may promote independent mobility in older women.

Healthcare professionals' perspectives and experiences of osteoporosis medication treatment: a qualitative systematic review.

This systematic review aimed to explore healthcare professionals' (HCPs) experiences and perspectives of osteoporosis medication treatment through thematic synthesis of qualitative studies. We found themes about how osteoporosis is perceived as a disease, treatment decision-making and what empowers HCPs to provide the best possible care. PURPOSE: The systematic review aimed to describe the perspectives and experiences of HCPs regarding osteoporosis medication treatment. METHODS: We performed searches in four electronic databases (Medline, Embase, PsycINFO and CINAHL) from database inception until May 2023 in any language. Data was analysed through inductive thematic synthesis. RESULTS: We included 27 primary studies that incorporated the views of 495 different HCPs. The following themes were identified: low-priority disease, challenges in treatment decision-making, minimising drug burden, conscious of communication barriers, fragmented care and advice, confidence through experience and collaboration. CONCLUSIONS: HCPs were enthusiastic about optimising osteoporosis care through interprofessional collaboration and expertise, as well as educating and monitoring patients on treatment. They advocated for safety, comfort and reducing overall drug burden, especially in older patients with comorbidities. However, they had differences in opinions regarding who has responsibility for diagnosing and treating osteoporosis and struggled to provide the best possible care due to competing priorities, limited time and lack of adequate knowledge or evidence. The findings highlight the important and complementary role of different HCPs in osteoporosis treatment through a multidisciplinary model of care.

Grass-Fed and Non-Grass-Fed Whey Protein Consumption Do Not Attenuate Exercise-Induced Muscle Damage and Soreness in Resistance-Trained Individuals: A Randomized, Placebo-Controlled Trial.

Eccentric muscle contractions can cause structural damage to muscle cells resulting in temporarily decreased muscle force production and soreness. Prior work indicates pasture-raised dairy products from grass-fed cows have greater anti-inflammatory and antioxidant properties compared to grain-fed counterparts. However, limited research has evaluated the utility of whey protein from pasture-raised, grass-fed cows to enhance recovery compared to whey protein from non-grass-fed cows. Therefore, using a randomized, placebo-controlled design, we compared the effect of whey protein from pasture-raised, grass-fed cows (PRWP) to conventional whey protein (CWP) supplementation on indirect markers of muscle damage in response to eccentric exercise-induced muscle damage (EIMD) in resistance-trained individuals. Thirty-nine subjects (PRWP, n = 14; CWP, n = 12) completed an eccentric squat protocol to induce EIMD with measurements performed at 24, 48, and 72 h of recovery. Dependent variables included: delayed onset muscle soreness (DOMS), urinary titin, maximal isometric voluntary contraction (MIVC), potentiated quadriceps twitch force, countermovement jump (CMJ), and barbell back squat velocity (BBSV). Between-condition comparisons did not reveal any significant differences (p ≤ 0.05) in markers of EIMD via DOMS, urinary titin, MIVC, potentiated quadriceps twitch force, CMJ, or BBSV. In conclusion, neither PRWP nor CWP attenuate indirect markers of muscle damage and soreness following eccentric exercise in resistance-trained individuals.

Computational fluid dynamics of upper airway aerodynamics for exercise-induced laryngeal obstruction: A feasibility study.

Objective: Use of computational fluid dynamic (CFD) simulations to measure the changes in upper airway geometry and aerodynamics during (a) an episode of Exercise-Induced Laryngeal Obstruction (EILO) and (b) speech therapy exercises commonly employed for patients with EILO. Methods: Magnetic resonance imaging stills of the upper airway including the nasal and oral cavities from an adult female were used to re-construct three-dimensional geometries of the upper airway. The CFD simulations were used to compute the maximum volume flow rate (l/s), pressure (Pa), airflow velocity (m/s) and area of cross-section opening in eight planes along the vocal tract, separately for inhalation and exhalation. Results: Numerical predictions from three-dimensional geometrical modeling of the upper airway suggest that the technique of nose breathing for inhalation and pursed lip breathing for exhalation show most promising pressure conditions and cross-sectional diameters for rescue breathing exercises. Also, if EILO is due to the constriction at the vocal fold level, then a quick sniff may also be a proper rescue inhalation exercise. EILO affects both the inspiratory and the expiratory phases of breathing. Conclusions: A prior knowledge of the supraglottal aerodynamics and the corresponding upper airway geometry from CFD analysis has the potential to assist the clinician in choosing the most effective rescue breathing technique for optimal functional outcome of speech therapy intervention in patients with EILO and in understanding the pathophysiology of EILO on a case-by-case basis with future studies. Level of Evidence: 4.

Ecological Momentary Assessment of Midlife Adults' Daily Stress: Protocol for the Stress Reports in Variable Environments (STRIVE) App Study.

BACKGROUND: Daily stressors are associated with cognitive decline and increased risk of heart disease, depression, and other debilitating chronic illnesses in midlife adults. Daily stressors tend to occur at home or at work and are more frequent in urban versus rural settings. Conversely, spending time in natural environments such as parks or forests, or even viewing nature-themed images in a lab setting, is associated with lower levels of perceived stress and is hypothesized to be a strong stress "buffer," reducing perceived stress even after leaving the natural setting. However, many studies of daily stress have not captured environmental contexts and relied on end-of-day recall instead of in-the-moment data capture. With new technology, these limitations can be addressed to enhance knowledge of the daily stress experience. OBJECTIVE: We propose to use our novel custom-built Stress Reports in Variable Environments (STRIVE) ecological momentary assessment mobile phone app to measure the experience of daily stress of midlife adults in free-living conditions. Using our app to capture data in real time will allow us to determine (1) where and when daily stress occurs for midlife adults, (2) whether midlife adults' daily stressors are linked to certain elements of the built and natural environment, and (3) how ecological momentary assessment measurement of daily stress is similar to and different from a modified version of the popular Daily Inventory of Stressful Events measurement tool that captures end-of-day stress reports (used in the Midlife in the United States [MIDUS] survey). METHODS: We will enroll a total of 150 midlife adults living in greater Indianapolis, Indiana, in this study on a rolling basis for 3-week periods. As those in underrepresented minority groups and low-income areas have previously been found to experience greater levels of stress, we will use stratified sampling to ensure that half of our study sample is composed of underrepresented minorities (eg, Black, American Indian, Hispanic, or Native Pacific Islanders) and approximately one-third of our sample falls within low-, middle-, and high-income brackets. RESULTS: This project is funded by the National Institute on Aging from December 2022 to November 2024. Participant enrollment began in August 2023 and is expected to finish in July 2024. Data will be spatiotemporally analyzed to determine where and when stress occurs for midlife adults. Pictures of stressful environments will be qualitatively analyzed to determine the common elements of stressful environments. Data collected by the STRIVE app will be compared with retrospective Daily Inventory of Stressful Events data. CONCLUSIONS: Completing this study will expand our understanding of midlife adults' experience of stress in free-living conditions and pave the way for data-driven individual and community-based intervention designs to promote health and well-being in midlife adults.

Perinatal depression screening in community pharmacy: Exploring pharmacists' roles, training and resource needs using content analysis.

BACKGROUND: Perinatal depression (PND) screening is often recommended in primary care settings, which includes the community pharmacy setting. However, there is limited research exploring pharmacists' perspectives on their roles in screening for perinatal mental illness. AIM: This study aimed to explore pharmacists' views of pharmacists' roles in PND screening, as well as training and resource needs for PND screening in community pharmacy settings. METHOD: A questionnaire including three open-ended questions focusing on pharmacists' perspectives of their role in PND screening, their training, and resource needs in this area, was disseminated to pharmacists across Australia via professional organisations and social media. Each open-ended question was separately analysed by inductive content analysis. Subcategories were deductively mapped to the Theoretical Framework of Acceptability. RESULTS: Responses (N = 149) from the first open-ended question about pharmacists' roles in PND screening resulted in three categories (PND screening in primary care settings will support the community, community pharmacy environment, and system and policy changes) and ten subcategories. Responses to question two on training needs (n = 148) were categorised as: training content, training length, and training delivery while responses about resource needs (n = 147) fell into three categories: adapting community pharmacy operating structures, pharmacist-specific resources, and consumer-specific resources. CONCLUSION: While some pharmacists were accepting of a role in PND screening due to pharmacists' accessibility and positive relationships with consumers, others had concerns regarding whether PND screening was within pharmacists' scope of practice. Further training and resources are needed to facilitate pharmacists' roles in PND screening, referral and care.
