An unbiased, sustainable, evidence-informed Universal Food Guide: a timely template for national food guides.

BACKGROUND: Although national food guides are designed, ostensibly, to translate scientific evidence with respect to food, dietary patterns, and health, their development has increasingly become a corporate/political process as well as scientific one; often with corporate/political influences overriding science. Our aim was to construct an unbiased, sustainable, evidence-informed Universal Food Guide to serve as a template for countries to develop their unique guides, thereby, provide a valid resource for health professionals, health authorities, and the public. METHODS: To address our aim, we conducted an integrative review of multiple evidence-informed sources (e.g., established databases, evidence syntheses, scholarly treatises, and policy documents) related to four areas: 1. Food guides' utility and conflicts of interest; 2. The evidence-based healthiest diet; 3. Constituents of the Universal Food Guide template; and 4. Implications for population health; regulation/governance; environment/climate/planetary health; and ethics. RESULTS: The eating pattern that is healthiest for humans (i.e., most natural, and associated with maximal health across the life cycle; reduced non-communicable disease (NCD) risk; and minimal end-of-life illness) is whole food, low fat, plant-based, especially vegan, with the absence of ultra-processed food. Disparities in national food guide recommendations can be explained by factors other than science, specifically, corporate/political interests reflected in heavily government-subsidized, animal-sourced products; and trends toward dominance of daily consumption of processed/ultra-processed foods. Both trends have well-documented adverse consequences, i.e., NCDs and endangered environmental/planetary health. Commitment to an evidence-informed plant-based eating pattern, particularly vegan, will reduce risks/manifestations of NCDs; inform healthy food and nutrition policy regulation/governance; support sustainable environment/climate and planetary health; and is ethical with respect to 'best' evidence-based practice, and human and animal welfare. CONCLUSION: The Universal Food Guide that serves as a template for national food guides is both urgent and timely given the well-documented health-harming influences that corporate stakeholders/politicians and advisory committees with conflicts of interest, exert on national food guides. Such influence contributes to the largely-preventable NCDs and environmental issues. Policy makers, health professionals, and the public need unbiased, scientific evidence as informed by the Universal Food Guide, to inform their recommendations and choices.

Academy of Plant-based Physical Therapy: overdue to address a nutrition crisis with a transformative population approach.

This timely evidence synthesis supports the need for an Academy of Plant-based Physical Therapy. Given epidemiological and empirical evidence and the profession's values and practice scope, the time has come for a specialty of plant-based physical therapy based on population health principles. This review connects these factors. Non-communicable diseases (NCDs) are largely nutrition-related resulting from unnatural elements of our diet (i.e., heart disease, several cancers, hypertension, stroke, diabetes, obesity, gastrointestinal diseases, autoimmune diseases, renal disease, and Alzheimer's disease). Most adults, even children, have NCD risk factors or manifestations. Alternatively, plant-based nutrition can prevent, manage, as well as potentially reverse these diseases, as well as augment conventional physical therapy outcomes by reducing inflammation and pain. Proposed competencies for plant-based physical therapists include high-level competency in health and NCD risk assessments/evaluations, to establish population health-informed nutrition needs for maximal health, healing and repair, in turn, function and wellbeing; and assessment of patients' nutrition-related knowledge, beliefs/attitudes, self-efficacy, and readiness-to-change. Population-informed nutritional counseling is initiated as indicated. An Academy of Plant-based Physical Therapy could advance the profession globally at this point in history and also serve as a role model to other health professions through practicing evidence-based, plant-based nutrition built upon population health principles.

Short-term effects of mobilization on oxygenation in patients after open surgery for pancreatic cancer: a randomized controlled trial.

BACKGROUND: Despite the unequivocal role of progressive mobilization in post-surgical patient management, its specific effects and timing, particularly after abdominal surgery, remain debated. This study's aim was to examine the short-term effects of mobilization on oxygenation in hemodynamically stable patients after open surgery for pancreatic cancer. METHODS: A randomized controlled clinical trial was conducted in which patients (n = 83) after open pancreatic surgery were randomized to either the same-day mobilization group (mobilized when hemodynamically stable within four hours after surgery) or the next-day mobilization group (mobilized first time in the morning of the first post-operative day). Mobilization was prescribed and modified based on hemodynamic and subjective responses with the goal of achieving maximal benefit with minimal risk. Blood gas samples were taken three times the evening after surgery; and before and after mobilization on the first post-operative day. Spirometry was conducted pre-operatively and on the first post-operative day. Adverse events and length of stay in postoperative intensive care were also recorded. RESULTS: With three dropouts, 80 patients participated (40 per group). All patients in the same-day mobilization group, minimally sat over the edge of the bed on the day of surgery and all patients (both groups) minimally sat over the edge of the bed the day after surgery. Compared with patients in the next-day mobilization group, patients in the same-day mobilization group required lower FiO2 and had higher SaO2/FiO2 at 1800 h on the day of surgery (p < .05). On the day after surgery, FiO2, SaO2/FiO2, PaO2/FiO2, and alveolar-arterial oxygen gradient, before and after mobilization, were superior in the same-day mobilization group (p < 0.05). No differences were observed between groups in PCO2, pH, spirometry or length stay in postoperative intensive care. CONCLUSIONS: Compared with patients after open pancreatic surgery in the next-day mobilization group, those in the same-day mobilization group, once hemodynamically stable, improved oxygenation to a greater extent after mobilization. Our findings support prescribed progressive mobilization in patients after pancreatic surgery (when hemodynamically stable and titrated to their individual responses and safety considerations), on the same day of surgery to augment oxygenation, potentially helping to reduce complications and hasten functional recovery. TRIAL REGISTRATION: This prospective RCT was carried out at the Sahlgrenska University Hospital, Sweden. The study was approved by the Regional Ethical Review Board in Gothenburg (Registration number: 437-17). TRIAL REGISTRATION: "FoU in Sweden" (Research and Development in Sweden, URL: https://www.researchweb.org/is/vgr ) id: 238701 Registered 13 December 2017 and Clinical Trials (URL:clinicaltrials.gov) NCT03466593.

Predictive variables for poor long-term physical recovery after intensive care unit stay: An exploratory study.

BACKGROUND: Elucidating factors that influence physical recovery of survivors after an intensive care unit (ICU) stay is paramount in maximizing long-term functional outcomes. We examined potential predictors for poor long-term physical recovery in ICU survivors. METHODS: Based on secondary analysis of a trial of 50 ICU patients who underwent mobilization in the ICU and were followed for one year, linear regression analysis examined the associations of exposure variables (baseline characteristics, severity of illness variables, ICU-related variables, and lengths of ICU and hospital stay), with physical recovery variables (muscle strength, exercise capacity, and self-reported physical function), measured one year after ICU discharge. RESULTS: When the data were adjusted for age, female gender was associated with reduced muscle strength (P = .003), exercise capacity (P < .0001), and self-reported physical function (P = .01). Older age, when adjusted for gender, was associated with reduced exercise capacity (P < .001). After adjusting for gender and age, an association was observed between a lower score on one or two physical recovery variables and exposure variables, specifically, high body mass index, low functional independence, comorbidity and low self-reported physical function at baseline, muscle weakness at ICU discharge, and longer hospital stay. No adjustment was made for cumulative type I error rate due to small number of participants. CONCLUSION: Elucidating risk factors for poor long-term physical recovery after ICU stay, including gender, may be critical if mobilization and exercise are to be prescribed expediently during and after ICU stay, to ensure maximal long-term recovery.

Effects of Motor Skill-Based Training on Wheelchair Propulsion Biomechanics in Older Adults: A Randomized Controlled Trial.

OBJECTIVE: To identify whether motor skill-based training improves wheeling biomechanics in older adults and whether transfer or retention occurs. DESIGN: Randomized controlled trial. SETTING: Human mobility laboratory. PARTICIPANTS: Able-bodied older adults 50 years and older deemed ready to participate in physical activity (N=34). INTERVENTION: Participants were randomized to 1 of 3 groups: experimental group with 6 motor skill-based training sessions, active control group with dose-matched uninstructed practice, and the inactive control group (no training or practice). The experimental group's training sessions consisted of two 5-minute blocks of wheelchair propulsion training, separated by a 5-minute break, for a total of 60 minutes of wheeling. Breaks included education and discussion related to wheelchair propulsion. Training focused on increasing push angle, decreasing push frequency, decreasing negative braking forces, and using a circular wheeling pattern with smooth pushes. MAIN OUTCOME MEASURES: Temporal spatial and kinetic variables (ie, push angle, push frequency, total and tangential forces, negative force) were evaluated during steady-state wheeling and biomechanical variables were assessed with the SmartWheel Clinical Protocol to identify transfer. RESULTS: The training group significantly increased push angle and decreased push frequency compared with the practice (P<.05) and control groups (P<.05), which were retained over time and transferred to overground wheeling on tile (P≤.05). The dose-matched practice group did not differ from the inactive control group for any variables (P>.05). CONCLUSIONS: Older adults improve select biomechanical variables following motor skill-based training, which are retained over time and transfer to overground wheeling. Participants in the active control group did not improve with uninstructed practice compared with the inactive control group.

Discordance between Lifestyle-Related Health Practices and Beliefs of People Living in Kuwait: A Community-Based Study.

OBJECTIVE: To examine the concordance between lifestyle practices and beliefs of people living in Kuwait, and between their lifestyle practices and established evidence-informed recommendations for health. SUBJECTS AND METHODS: A cross-sectional interview questionnaire study was conducted using a convenience sample of 100 adults living in Kuwait (age range 19-75 years). The interview included sections on demographics, and lifestyle-related practices and beliefs related to smoking, diet/nutrition, physical activity/exercise, sleep, and stress. Diet/nutrition and physical activity/exercise benchmarks were based on international standards. Analyses included descriptive statistics and the χ2 test. RESULTS: Beliefs about the importance of nutrition in lifestyle-related conditions were limited, and this was apparent in participants' dietary habits, e.g., low consumption of fruit/vegetables and multigrains: 16 (16%) and 9 (9%) met the recommended guidelines, respectively. Ninety-nine (99%) believed physical activity/exercise affects health overall, and 44 (44%) exercised regularly. Of the sample of 100, 20 (20%) exercised in accordance with evidence-based recommendations for maximal health. Compared with beliefs about other lifestyle-related behaviors/attributes, respondents believed nutrition contributed more than stress to heart disease, cancer, and stroke, and stress contributed more than nutrition to hypertension and diabetes. CONCLUSION: In this study, our findings showed a discrepancy between lifestyle-related practices and beliefs, and between each of these and evidence-based recommendations for maximal health, i.e., not smoking, several servings of fruit and vegetables and whole-grain foods daily, healthy weight, restorative sleep, and low-to-moderate stress levels.

Effects of Person-Centered Physical Therapy on Fatigue-Related Variables in Persons With Rheumatoid Arthritis: A Randomized Controlled Trial.

OBJECTIVE: To examine effects of person-centered physical therapy on fatigue and related variables in persons with rheumatoid arthritis (RA). DESIGN: Randomized controlled trial. SETTING: Hospital outpatient rheumatology clinic. PARTICIPANTS: Persons with RA aged 20 to 65 years (N=70): intervention group (n=36) and reference group (n=34). INTERVENTIONS: The 12-week intervention, with 6-month follow-up, focused on partnership between participant and physical therapist and tailored health-enhancing physical activity and balancing life activities. The reference group continued with regular activities; both groups received usual health care. MAIN OUTCOME MEASURES: Primary outcome was general fatigue (visual analog scale). Secondary outcomes included multidimensional fatigue (Bristol Rheumatoid Arthritis Fatigue Multi-Dimensional Questionnaire) and fatigue-related variables (ie, disease, health, function). RESULTS: At posttest, general fatigue improved more in the intervention group than the reference group (P=.042). Improvement in median general fatigue reached minimal clinically important differences between and within groups at posttest and follow-up. Improvement was also observed for anxiety (P=.0099), and trends toward improvements were observed for most multidimensional aspects of fatigue (P=.023-.048), leg strength/endurance (P=.024), and physical activity (P=.023). Compared with the reference group at follow-up, the intervention group improvement was observed for leg strength/endurance (P=.001), and the trends toward improvements persisted for physical (P=.041) and living-related (P=.031) aspects of fatigue, physical activity (P=.019), anxiety (P=.015), self-rated health (P=.010), and self-efficacy (P=.046). CONCLUSIONS: Person-centered physical therapy focused on health-enhancing physical activity and balancing life activities showed significant benefits on fatigue in persons with RA.

What is the role of lifestyle behaviour change associated with non-communicable disease risk in managing musculoskeletal health conditions with special reference to chronic pain?

BACKGROUND: Other than activity and exercise, lifestyle practices such as not smoking and healthy nutrition, well established for preventing and managing lifestyle-related non-communicable diseases (i.e., heart disease, cancer, hypertension, stroke, obstructive lung disease, diabetes, and obesity), are less emphasized in the physical therapy guidelines for addressing chronic pain, e.g., back pain. This state-of-the-art review examines the relationships between lifestyle behaviours and musculoskeletal health, with special reference to chronic pain, and their clinical and research implications. DISCUSSION: A state-of-the-art review was conducted to synthesize evidence related to lifestyle factors (not smoking, healthy diet, healthy weight, optimal sleep and manageable stress, as well as physical activity) and musculoskeletal health, with special reference to chronic pain. The findings support that health behaviour change competencies (examination/assessment and intervention/treatment) may warrant being included in first-line management of chronic pain, either independently or in conjunction with conventional physical therapy interventions. To address knowledge gaps in the literature however three lines of clinical trial research are indicated: 1) to establish the degree to which traditional physical therapy interventions prescribed for chronic pain augment the benefits of lifestyle behaviour change; 2) to establish the degree to which adopting healthier lifestyle practices, avoids or reduces the need for conventional physical therapy; and 3) to establish whether patients/clients with healthier lifestyles and who have chronic pain, respond more favourably to conventional physical therapy interventions than those who have less healthy lifestyles. SUMMARY: Lifestyle behaviour change is well accepted in addressing lifestyle-related non-communicable diseases. Compelling evidence exists however supporting the need for elucidation of the role of negative lifestyle behaviours on the incidence of chronic pain, and the role of positive lifestyle behaviours on its incidence and effective management. Addressing lifestyle behaviour change in patients/clients with chronic pain, e.g., back pain, as a first-line intervention might not only constitute a novel approach, but also reduce the socioeconomic burden related to chronic pain as well as non-communicable diseases.

Toward core inter-professional health promotion competencies to address the non-communicable diseases and their risk factors through knowledge translation: curriculum content assessment.

BACKGROUND: To increase the global impact of health promotion related to non-communicable diseases, health professionals need evidence-based core competencies in health assessment and lifestyle behavior change. Assessment of health promotion curricula by health professional programs is a first step. Such program assessment is a means of 1. demonstrating collective commitment across health professionals to prevent non-communicable diseases; 2. addressing the knowledge translation gap between what is known about non-communicable diseases and their risk factors consistent with 'best' practice; and, 3. establishing core health-based competencies in the entry-level curricula of established health professions. DISCUSSION: Consistent with the World Health Organization's definition of health (i.e., physical, emotional and social wellbeing) and the Ottawa Charter, health promotion competencies are those that support health rather than reduce signs and symptoms primarily. A process algorithm to guide the implementation of health promotion competencies by health professionals is described. The algorithm outlines steps from the initial assessment of a patient's/client's health and the indications for health behavior change, to the determination of whether that health professional assumes primary responsibility for implementing health behavior change interventions or refers the patient/client to others.An evidence-based template for assessment of the health promotion curriculum content of health professional education programs is outlined. It includes clinically-relevant behavior change theory; health assessment/examination tools; and health behavior change strategies/interventions that can be readily integrated into health professionals' practices. SUMMARY: Assessment of the curricula in health professional education programs with respect to health promotion competencies is a compelling and potentially cost-effective initial means of preventing and reversing non-communicable diseases. Learning evidence-based health promotion competencies within an inter-professional context would help students maximize use of non-pharmacologic/non-surgical approaches and the contribution of each member of the health team. Such a unified approach would lead patients/clients to expect their health professionals to assess their health and lifestyle practices, and empower and support them in achieving lifelong health. Benefits of such curriculum assessment include a basis for reflection and discussion within and across health professional programs that could impact the epidemic of non-communicable diseases globally, through inter-professional education and evidence-based practice related to health promotion.

Culture as a variable in health research: perspectives and caveats.

To augment the rigor of health promotion research, this perspective article describes how cultural factors impact the outcomes of health promotion studies either intentionally or unintentionally. It proposes ways in which these factors can be addressed or controlled in designing studies and interpreting their results. We describe how variation within and across cultures can be considered within a study, e.g. the conceptualization of research questions or hypotheses, and the methodology including sampling, surveys and interviews. We provide multiple examples of how culture influences the interpretation of study findings. Inadequately accounting or controlling for cultural variations in health promotion studies, whether they are planned or unplanned, can lead to incomplete research questions, incomplete data gathering, spurious results and limited generalizability of the findings. In health promotion research, factors related to culture and cultural variations need to be considered, acknowledged or controlled irrespective of the purpose of the study, to maximize the reliability, validity and generalizability of study findings. These issues are particularly relevant in contemporary health promotion research focusing on global lifestyle-related conditions where cultural factors have a pivotal role and warrant being understood.

Status of animal experimentation in nutrition and dietetic research: Policies of 100 leading journals and new approach methodologies.

Given animal research is challenged with inadequacies, e.g., animal-to-human knowledge translation, ethical considerations, and cost:benefit, new approach methodologies (NAMs) have been proposed as a replacement. With reference to the field of nutrition and dietetics, our aim was to examine the policies of its leading journals regarding human-based vs. traditional animal-based research; and to explore emerging NAMs that provide alternatives to animal experimentation. We reviewed 100 leading journals from an established database (SCImago Journal Rankings) in the nutrition and dietetics category for the year 2022. Eighty-three journals met the inclusion criteria. NAMs were extracted from a range of established sources. 9.6% (n = 8) of journals state they do not publish animal-based studies; 4.8% (n = 4) consider animal studies with qualifications, whereas the remaining 85.5% (n = 71) publish animal studies without qualification. Across sources, NAMs commonalities were identified including in vitro, in chemico, and in silico methods; and individual and population-based studies. Of leading nutrition/dietetic journals, relatively few have shifted to strictly non-animal methods. Greater attention to the increasing range of NAMs may not only reduce the need for animal research in the field, but may provide superior human-relevant outcomes. Studies are needed to establish their potential superiority.

Benchmarking curriculum content in entry-level health professional education with special reference to health promotion practice in physical therapy: a multi-institutional international study.

Health promotion (HP) warrants being a clinical competency for health professionals given the global burden of lifestyle-related conditions; these are largely preventable with lifestyle behavior change. Physical therapists have a practice pattern conducive to HP, including lifestyle behavior change. The extent to which HP content is included in entry-level physical therapy (PT) curricula, and how it is taught however, is unknown. The aim of this study was to benchmark lifestyle behavior HP content within entry-level curricula of international PT programs. The sampling frame included 258 accredited PT academic programs spanning six countries. An internet-based survey was used to assess HP curricular content. Descriptive questions for HP topics (smoking cessation, nutrition, weight control, alcohol consumption, exercise, and stress management) included hours allotted and instructional methods used. Chi square tests examined differences between the proportion of programs in the United States (US) and other countries (combined) for HP topics, and among HP topics regarding instructional methods. The response rate was 48 %. Most programs (>80 %) included all HP topics except alcohol consumption (65.5 % of programs). Instructional methods used were primarily theory-based; few programs (range 2.6-24.1 %) combined theory, practical and attainment of clinical competency for all HP topics (exercise prescription notwithstanding). Proportionally, more US programs included alcohol and nutrition than other countries combined. Overall, HP lifestyle behavior topics were included to varying extent; however, instructional methods used and hours allotted per topic varied across PT curricula. Universal standards of HP practice as a clinical competency are warranted within the profession.

FMO rewires metabolism to promote longevity through tryptophan and one carbon metabolism in C. elegans.

Flavin containing monooxygenases (FMOs) are promiscuous enzymes known for metabolizing a wide range of exogenous compounds. In C. elegans, fmo-2 expression increases lifespan and healthspan downstream of multiple longevity-promoting pathways through an unknown mechanism. Here, we report that, beyond its classification as a xenobiotic enzyme, fmo-2 expression leads to rewiring of endogenous metabolism principally through changes in one carbon metabolism (OCM). These changes are likely relevant, as we find that genetically modifying OCM enzyme expression leads to alterations in longevity that interact with fmo-2 expression. Using computer modeling, we identify decreased methylation as the major OCM flux modified by FMO-2 that is sufficient to recapitulate its longevity benefits. We further find that tryptophan is decreased in multiple mammalian FMO overexpression models and is a validated substrate for FMO-2. Our resulting model connects a single enzyme to two previously unconnected key metabolic pathways and provides a framework for the metabolic interconnectivity of longevity-promoting pathways such as dietary restriction. FMOs are well-conserved enzymes that are also induced by lifespan-extending interventions in mice, supporting a conserved and important role in promoting health and longevity through metabolic remodeling.

Association between habitual sleep duration and blood pressure and clinical implications: a systematic review.

UNLABELLED: Elucidation of the association between short sleep duration and elevated blood pressure has implications for assessing and managing hypertension in adults. OBJECTIVE: To assess the relationship between sleep duration and blood pressure, and its role in the etiology of hypertension. METHODS: On a systematic search from MEDLINE, EMBASE, CINAHL, PEDro, PsychINFO and grey literature were included articles with participants over 18 years, reported sleep duration, measured blood pressure or diagnosed hypertension, and the relationship between sleep duration and blood pressure was analyzed. RESULTS: Of 2522 articles initially identified, 11 studies met the inclusion criteria. Sample sizes ranged from 505 to 8860 (aged ≥ 20-98 years). Five studies (aged ≥ 58-60 years) determined that sleep duration and blood pressure were unrelated. In younger adults, five studies reported an association between short sleep duration and hypertension before adjustment for confounding variables; only the findings from one study remained significant after adjustment. Two studies supported a sex association; women who sleep less than 5-6 h nightly are at greater risk of developing hypertension. CONCLUSION: Sleep duration and blood pressure are associated in both women and adults under 60 years. Controlled studies are needed to elucidate confounding factors and the degree to which sleep profiles could augment diagnosis of hypertension and sleep recommendations to prevent or manage hypertension.

A health and lifestyle framework: An evidence-informed basis for contemporary physical therapist clinical practice guidelines with special reference to individuals with heart failure.

BACKGROUND AND PURPOSE: This study proposes contemporary physical therapist clinical practice guidelines (CPGs) with special reference to heart failure (HF) be grounded in an evidence-informed integrative health and lifestyle framework to not only better reflect the totality and weighting of the literature, but also in the interest of superior patient, clinical, and economic outcomes. METHODS: As an illustration, a health and lifestyle framework is described to underpin, thereby complement, recently published physical therapist CPGs for individuals with HF. RESULTS: The case for the framework, an alternative to a single-disease biomedical perspective, is consistent with 21st century professional and epidemiologic indicators. Four themes that emerged from the HF CPGs and further support such a framework, emerged that is, limitations of conventionally constructed CPGs; physical therapists' scope of practice as "health" professionals; "best" practice in an era of NCDs including HF; and superior economic benefit. DISCUSSION: A health and lifestyle framework underpinning contemporary physical therapist CPGs will enable clinicians to better appreciate the power of lifestyle change in maximizing the health of the heart, its healing and repair, and in mitigating and reversing signs and symptoms of cardiac dysfunction. Further, a focus on health and lifestyle will augment the benefits of the core, evidence-based, key action statements related to exercise in the HF CPGs.

Augmented behavioral medicine competencies in physical therapy students' clinical reasoning with a targeted curriculum: a final-semester cohort-comparison study.

BACKGROUND: Knowledge regarding the impact of curricula with behavioral medicine content and competencies (BMCC) on physical therapy (PT) students' clinical reasoning skills is lacking. OBJECTIVES: The primary objective was to compare the clinical reasoning skills, focusing on clients' behavioral change, of entry-level PT students with or without BMCC in their curricula. The secondary objective was to compare students' attitudes and beliefs in a biomedical and biopsychosocial practice orientation. METHODS: Swedish final-semester PT students (n = 151) completed the Reasoning 4 Change (R4C) instrument and the Pain Attitudes and Beliefs Scale for Physiotherapists. A blueprint was used for curricular categorization. The independent t-test was used. RESULTS: Students attending programs with BMCC curricula (n = 61) had superior scores compared with students without BMCC curricula (n = 90) in the following R4C variables, all of which were related to clinical reasoning focused on behavioral change: Knowledge, Cognition, Self-efficacy, Input from the client, Functional behavioral analysis, and Strategies for behavioral change. Students who did not receive BMCC curricula scored higher in the R4C contextual factors and reported a greater biomedical practice orientation than students receiving BMCC curricula. There was no difference in the biopsychosocial practice orientation between groups. CONCLUSIONS: Our findings support the benefit of structured entry-level PT curricula with BMCC on final-semester students' clinical reasoning skills focused on behavioral change and their level of biomedical practice orientation. Further, our findings elucidated educational opportunities to augment students' self-efficacy and strengthen their behavioral competencies in clinical reasoning. For the generalizability of the results further research in other contexts is needed.

Long-term effects of physical activity prescription after bariatric surgery: A randomized controlled trial.

PURPOSE: This study examined the effects of physical activity prescription (PAP) in patients after gastric bypass surgery. Patients' physical activity (PA) levels and outcomes were followed over their first postoperative year. METHODS: Patients slated for bariatric surgery were randomized to a control group (n = 64) (basic information about postoperative PA) or an intervention group (n = 57) (also received physical therapist-prescribed PAP). Outcome measures were self-reported PA/exercise and sedentary time; and weight, waist circumference, blood pressure, and blood lipids; recorded pre-operatively and at 2, 6, and 12 months postoperatively. Follow-ups were conducted by nurses/dieticians. Trial registration: "Research and Development in Sweden" number 107371. RESULTS: There were no differences between the groups except for higher level of PA (579 vs. 182 minutes/week) six months after surgery (p = .046) and a larger decrease in cholesterol (-24 vs. -8%) after a year (p = .017) in the intervention group. Patients in both groups lost considerable weight, had reduced waist circumference, and increased PA (p < .001). CONCLUSION: Although marked differences between groups were not observed over one year, the intervention group increased its PA 6-months postoperatively, but not at other time points. Whether long-term outcomes of PAP use are more robust with physical therapist participation across follow-ups warrants study.

Immuno-modulation with lifestyle behaviour change to reduce SARS-CoV-2 susceptibility and COVID-19 severity: goals consistent with contemporary physiotherapy practice.

Lifestyle-related non-communicable diseases (NCDs) and their risk factors are unequivocally associated with SARS-CoV-2 susceptibility and COVID-19 severity. NCD manifestations and their lifestyle risks are associated with chronic low-grade systemic inflammation (CLGSI). This review supports that immuno-modulation with positive lifestyle change aimed at reducing SARS-CoV-2 susceptibility and COVID-19 severity, is a goal consistent with contemporary physiotherapy practice. Physiotherapists have a long tradition of managing a , thus, managing CLGSI is a logical extension. Improving patients' lifestyle practices also reduces their NCD risks and increases activity/exercise capacity, health and wellbeing - all principal goals of contemporary physiotherapy. The COVID-19 pandemic lends further support for prioritising health and lifestyle competencies including smoking cessation; whole food plant-based nutrition; healthy weight; healthy sleep practices; and stress management; in conjunction with reducing sedentariness and increasing physical activity/exercise, to augment immunity as well as function and overall health and wellbeing. To support patients' lifestyle change efforts, physiotherapists may refer patients to other health professionals. The authors conclude that immuno-modulation with lifestyle behaviour change to reduce susceptibility to viruses including SARS-CoV-2, is consistent with contemporary physiotherapy practice. Immuno-modulation needs to be reflected in health competencies taught in physiotherapy professional education curricula and taught at standards comparable to other established interventions.

Serotonin and dopamine modulate aging in response to food odor and availability.

An organism's ability to perceive and respond to changes in its environment is crucial for its health and survival. Here we reveal how the most well-studied longevity intervention, dietary restriction, acts in-part through a cell non-autonomous signaling pathway that is inhibited by the presence of attractive smells. Using an intestinal reporter for a key gene induced by dietary restriction but suppressed by attractive smells, we identify three compounds that block food odor effects in C. elegans, thereby increasing longevity as dietary restriction mimetics. These compounds clearly implicate serotonin and dopamine in limiting lifespan in response to food odor. We further identify a chemosensory neuron that likely perceives food odor, an enteric neuron that signals through the serotonin receptor 5-HT1A/SER-4, and a dopaminergic neuron that signals through the dopamine receptor DRD2/DOP-3. Aspects of this pathway are conserved in D. melanogaster. Thus, blocking food odor signaling through antagonism of serotonin or dopamine receptors is a plausible approach to mimic the benefits of dietary restriction.
