Purpose: The Compendium of Physical Activities is commonly recognized as an adjuvant to prescribing physical activities and estimating energy expenditure. But its applicability in clinical populations is less clear. Thus, the purpose of this study was to measure the metabolic cost of activities of daily living in volunteers implanted with an integrated sensor pacemaker and compare these values with those in the compendium.Methods: On the first day of testing, patients underwent a symptom-limited cardiopulmonary graded exercise test using the Minnesota Pacemaker Response Exercise protocol. The next day, an Activities of Daily Living protocol was performed in a model apartment in the exercise physiology lab. Energy expenditure and heart rate response were measured during 5 common activities of daily living: vacuuming, changing bed linens, carrying and unpacking groceries, changing and folding laundry, and walking on a treadmill. Measured values (mean +/- SD) were compared with compendium values using a one-sample t-test. Relative intensity was established using peak measurements obtained during the graded exercise test.Results: The mean MET values achieved during all 5 activities of daily living were significantly higher than those listed in the compendium. The relative demands of the activities of daily living, as expressed as a percentage of VO2 peak, ranged from 46 to 62%.Conclusion: When prescribing exercise or physical activities for individuals with rate-responsive pacemakers, direct measurement vs. estimation of energy expenditure would seem prudent, as the energy requirements of activities of daily living may not be accurately estimated by the compendium.

Background: Tricyclic antidepressants have been demonstrated in the laboratory to have anticancer properties. A recent study by our group also suggested a protective effect against development of colorectal cancer and glioma. This study aims to determine whether the anticancer action of tricyclics translates to improved survival in these cancers post-diagnosis. Methods: A study using the General Practice Research Database examined whether tricyclic antidepressant exposure in the months following diagnosis of glioma or colorectal cancer would affect longer term all-cause mortality. Cox proportional hazards modelling adjusted for age, gender, smoking, body mass index, comorbidity, and diagnosed depression. Results: A cohort of 1,364 glioma and 16,519 colorectal cancer patients were identified. There was a non-significant reduction in the hazard for glioma patients treated with tricyclics (HR = 0.83, CI = 0.53-1.30). This was mainly found in patients who were not previously exposed to tricyclics (HR = 0.56, CI = 0.26-1.18). In contrast, a significant increase in hazard was found for colorectal cancer (HR = 1.37, CI = 1.21-1.54). This was mostly in patients prescribed low-dose tricyclics (HR = 1.57, CI = 1.33-1.86). Conclusions: We have shown no significant mortality reduction in colorectal cancer or glioma patients treated with tricyclics. An apparent detrimental effect observed in colorectal cancer may be related to prescription of low-dose tricyclics in the management of pain related to disseminated cancer. We cannot rule out small effects or an effect that occurs exclusively at higher doses. Blinded clinical studies may therefore be the only method of determining efficacy in glioma patients.

The assessment of cognitive function in individuals of culturally and linguistically diverse background poses considerable challenges for the psychologist, particularly when English proficiency is limited. This study explored the effects of diverse cultural background and non-Western educational background on Wechsler Adult Intelligence Scale-Third edition (WAIS-III) and Wechsler Memory Scale-Third Edition (WMS-III) performances in moderate-severe traumatic brain injury within an outpatient rehabilitation setting. Participants were aged 16 -- 65 years and met careful selection criteria. IQ, index and age-scaled subtest scores were compared across three groups: (a) English-speaking background (n = 130), (b) culturally and linguistically diverse background and education completed in English (n = 33), and (c) culturally and linguistically diverse background and non-English education (n = 33). Cultural backgrounds included people of Asian, European, Middle Eastern, African and Oceania origin. Results were that the English-educated culturally and linguistically diverse group performed lower than the English-speaking background group on some verbal WAIS-III measures; effect sizes were small-moderate. The non-English-educated culturally and linguistically diverse group performed lower than both groups on several WAIS-III and one WMS-III measure, with large effect sizes. Clinical implications included the need for caution in interpreting test scores to avoid diagnostic errors and the need for further development of valid assessment tools. [ABSTRACT FROM AUTHOR]

The death of a child is a traumatic, nonnormative family life event. Although parental bereavement has received substantial attention, little research has focused on extended family members affected by a child's death, and still less on how multiple family members perceive and respond to one another following the loss. Guided by a life course perspective, this article examines social support between grandparents and their adult children in the aftermath of infant death. Through structured, open-ended interviews, 21 grandparents and 19 parents from 10 families described how they provided support to and received support from their intergenerational partners. Data were analyzed using a grounded theory approach. Six categories of support were identified: being present, acknowledgment, performing immediate tasks, information, unskilled support, and no support. Most support was provided by grandparents to adult children rather than from adult children to grandparents. All families reported significant support from at least one grandparent and nearly all families described ambivalent relationships that complicated support. Gender, family lineage, and family history were major influences. Multiple family perspectives about a significant life event contribute to our understanding about the intersection between individual and family life. [ABSTRACT FROM AUTHOR]

Family rituals provide a rich context in which to study the relation between ideology and action. Guided by the gender perspective, this article analyzes the experiences of 21 newly married heterosexual couples who described how they planned their weddings. The interplay among gender ideology, gender display, and gender assessment differed across three types of couples: traditional (n = 6), transitional (n = 10), and egalitarian (n = 5). An examination of gender assessment in transitional couples illustrates how holding competing ideologies contributes to the reproduction of hegemonic gendered work patterns within wedding planning.

Women use legacies to help family members articulate family identity, learn family history, and provide succeeding generations with information about family culture. Using feminist standpoint theory and the life-course perspective, this qualitative study examined the intergenerational transmissions that 30 older Armenian American mothers received and transmitted to succeeding generations within the sociohistorical experience of genocide. Mothers passed on legacies that included family stories, rituals/activities, and possessions. Because of multiple losses during the Armenian Genocide, they emphasized legacies that symbolized connection to family, underscored family cohesion, and accentuated ethnic identity. Tensions were evident as well because women's sense of responsibility for legacies clashed with their limited cultural knowledge, few inherited possessions, and the inevitable assimilation of their children and grandchildren into the dominant U.S. culture.

Integrating thought from critical feminist and disability theorists via a strategic social constructionist perspective, the authors analyzed 10 in-depth qualitative interviews to begin to understand the dialogue between (a) how nondisabled sisters understand themselves and their siblings with developmental disabilities and (b) wider systems of power or discourse. The women in this exploratory study described themselves as good sisters by portraying their siblings with disabilities as normal, emphasizing opportunities for moral enhancement, minimizing personal sacrifices, and accepting the gendered nature of family care. This study suggests that nondisabled sisters co-opt ideology that holds women accountable for moral conduct in families to oppose discourse that devalues people with disabilities. This ideology does not, however, help them transcend a gender system that requires mothers and sisters but not fathers and brothers to engage in family care. [ABSTRACT FROM AUTHOR]

Background: Frontotemporal dementia (FTD) is difficult to diagnose in the early stages and may be misdiagnosed as Alzheimer's disease (AD) or as a psychiatric disorder. This study aimed to investigate neuropsychological function in FTD of mild severity and compare it to that of mild AD and healthy control participants.Methods: The study comprised 11 individuals with FTD, 29 with AD and 27 healthy controls. Participants completed a comprehensive neuropsychological assessment in which each area of cognitive function was examined with several widely used clinical tests. Test scores were converted to age-corrected scaled scores and combined to form indices for six areas of cognitive function. These indices were attention, psychomotor speed, memory acquisition, memory recall, executive function and constructional ability.Results: The FTD group performed below the level of the controls in all areas except constructional ability. FTD and AD groups showed distinct patterns of neuropsychological performance. The FTD group showed predominantly executive dysfunction with less impaired memory function, while the AD group showed the opposite pattern. The capacity of the tests to discriminate between groups was good overall, with 90% of the total sample correctly classified. Predictive success for the FTD group was 64%, given a base rate of 16%.Conclusion: Administration of a comprehensive neuropsychological protocol including several tests of executive function allows increased certainty about accurate clinical diagnosis of mild FTD.

Objectives. The objectives of the present study were (1) to evaluate the pressor response to an isometric handgrip exercise in normotensive black and white males; (2) to measure plasma catecholamine levels pre- and post-exercise, as an index of sympathetic nervous system activity; and (3) to quantify the pressor response to bolus intravenous injections of phenylephrine (an alpha-specific agonist). Methods. Cardiovascular and catecholamine responses to an isometric handgrip exercise (3 minutes at 30% MVC) were measured in 15 normotensive blacks and whites. In another phase of the study, pressor responses to bolus injections of phenylephrine were assessed to evaluate alpha-adrenergic sensitivity. Results. The blood pressure in the blacks increased from 119/69 to 160/120 mm HG during isometric exercise, while in the whites it increased from 118/67 to 153/110 mm HG. The blacks exhibited a greater diastolic blood pressure reactivity, as evidenced by a significant race x time interaction (p < 0.05). The heart rate responses were not significantly different between the two groups. The plasma levels of norepinephrine were similar at rest, but were 25% lower in the blacks than in the whites following isometric exercise (p < 0.01). Black subjects also demonstrated an increased pressor response to intravenous injections of phenylephrine at rest (p < 0.05). Conclusions. The enhanced vascular sensitivity to norepinephrine may have contributed to the greater exercise pressor response in the blacks. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Using a feminist social constructionist perspective, we illuminate how aging mothers and their caregiving daughters negotiate issues of connection, autonomy, and conflict. METHODS: We conducted a qualitative analysis of videotaped interactions between 31 White mother-daughter pairs. RESULT: We found that the mothers and daughters mostly (a) were attentive and responsive, (b) preserved mothers' autonomy, and (c) minimized open conflict and tension. Subtle behavioral cues visible on the videotapes also exposed underlying emotional tension in these relationships. These cues alerted us to important variation in relationship quality among the pairs. Three patterns of relating emerged: (a) symmetrically connected, (b) asymmetrically connected, and (c) symmetrically constrained. DISCUSSION: Our exploratory study suggests that a balance between autonomy and connection is fundamental to the success of these mother-daughter caregiving relationships. Not only is it important for frail mothers to be responsive to their caregiving daughter's needs, but also it is important for daughters to support the autonomy and independence of their mothers. Our study also highlights the importance of attentiveness in these relationships. Even when mothers, because of illness and frailty, were less capable of attending to their daughters' lives, daughters in connected pairs interacted with their mothers in attentive ways. In constrained pairs, neither intergenerational partner was attentive. [ABSTRACT FROM AUTHOR]

Persistent physical interaction between male and female schistosome adult worms has long been shown to be crucial for their development and sexual maturation, particularly for the female. Although not fully understood, worm pairing promotes local molecular communication between sexes, driving gonad and vitellaria differentiation. In this opinion article we (i) summarise evidence concerning molecular interactions underlying the physical pairing, and (ii) propose a new paradigm whereby remote male-female molecular communication may play an overlooked role in parasite sexual maturation. In this context we discuss recent research that supports both physical and remote male-female interactions driving differentiation of the gonads/vitellaria. This remote communication between sexes may be mediated by excretory-secretory products (ESPs). Integrated hypotheses are presented to stimulate research in this important and emerging field., Competing Interests: Declaration of interests The authors declare no competing interests., (Copyright © 2024 The Author(s).

Abstract: McFadden, BA, Walker, AJ, Cintineo, HP, Bozzini, BN, Sanders, DJ, Chandler, AJ, and Arent, SM. Sex differences in physiological responses to a National Collegiate Athletic Association Division I soccer season. J Strength Cond Res 38(11): 1891-1899, 2024-Identifying physiological changes that occur in response to workload demands can help to elucidate athlete management and recovery strategies. The purpose of this study was to compare the physical and physiological demands between men and women throughout the course of a collegiate soccer season. Men ( N = 23) and women ( N = 26) soccer players participated in blood draws before preseason (T1) and every 4 weeks thereafter (T2-T4). Workload was determined at all practices and games via heart rate and global positioning satellite monitoring systems. Repeated measures multivariate analysis of variance and linear mixed models were used to assess workload and biomarker responses throughout the season ( p < 0.05). Both teams experienced the highest workloads during the first 4 weeks of the season ( p < 0.05), which was followed by several biomarker perturbations. Sex-by-Time interactions were observed for total cortisol, growth hormone, insulin-like growth factor-1, thyroxine, thyroid-stimulating hormone, vitamin D, and omega 3 fatty acid index ( p < 0.05). Additional Sex effects were observed for free and total testosterone, estrogen, prolactin, sex-hormone binding globulin, creatine kinase, and iron levels ( p < 0.05). Women soccer players experienced further Time effects for free cortisol, iron, ferritin, and percent transferrin saturation ( p < 0.05). Male soccer players experienced additional Time effects for total testosterone, estrogen, creatine kinase, interleukin-6, triiodothyronine, and ferritin ( p < 0.05). Despite similar patterns of change in workloads, differential fluctuations in physiological markers were observed between the sexes. Understanding sex differences in response to comparable workloads may enhance exercise prescriptions for better athlete management plans. Additional strategies to increase iron may be warranted in female athletes., (Copyright © 2024 National Strength and Conditioning Association.)

Objectives: In the UK, guidelines recommend pancreatic enzyme replacement therapy (PERT) to all people with unresectable pancreatic cancer. In 2023, we published a national audit of PERT which showed suboptimal prescribing and wide regional variation in England. The aim of this manuscript was to describe how we used the PERT audit to drive improvements in healthcare., Methods: Building on the PERT audit, we deployed an online dashboard which will deliver ongoing updates of the PERT audit. We developed a collaborative intervention with cancer nurse specialists (CNS) to improve care delivered to people with pancreatic cancer. The intervention called Creating a natiOnAL CNS pancrEatic cancer network to Standardise and improve CarE (COALESCE) will use the dashboard to evaluate improvements in prescribing of PERT., Results: We demonstrated how large databases of electronic healthcare records (EHRs) can be used to improve cancer care. The PERT audit was implemented into a dashboard for tracking the progress of COALESCE. We will measure improvements in PERT prescribing as the intervention with CNS progresses., Conclusions: Improving healthcare is an ongoing and iterative process. By implementing the PERT dashboard, we created a resource-efficient, automated evaluation method enabling COALESCE to deliver a sustainable change. National-scale databases of EHRs enable rapid cycles of audits, providing regular feedback to interventions, working systematically to deliver change. Here, the focus is on pancreatic cancer. However, this methodology is transferable to other areas of healthcare., Implications for Nursing Practice: Nurses play a key role in collecting good quality data which are needed in clinical audits to identify shortcomings in healthcare. Nurse-driven interventions can be designed to improve healthcare. In this study, we capitalize on the unique role of CNS coordinating care for every patient with cancer. COALESCE is the first national collaborative study which uses CNS as researchers and change agents., Competing Interests: Declaration of competing interest BG received research funding from the Laura and John Arnold Foundation, the NHS National Institute for Health Research (NIHR), the NIHR School of Primary Care Research, NHS England, the NIHR Oxford Biomedical Research Centre, the Mohn-Westlake Foundation, NIHR Applied Research Collaboration Oxford and Thames Valley, the Wellcome Trust, the Good Thinking Foundation, Health Data Research UK, the Health Foundation, the World Health Organization, UKRI MRC, Asthma UK, the British Lung Foundation, and the Longitudinal Health and Wellbeing strand of the National Core Studies program; he is a Non-Executive Director at NHS Digital; he also receives personal income from speaking and writing for lay audiences on the misuse of science.

Objective: Harmonized tools are essential for reliable data sharing and accurate identification of relevant factors in mental health research. The primary objective of this study was to create a harmonized questionnaire to collect demographic, clinical and behavioral data in diverse clinical trials in adult psychiatry., Methods: We conducted a literature review and examined 24 questionnaires used in previously published randomized controlled trials in psychiatry, identifying a total of 27 domains previously explored. Using a Delphi-method process, a task force team comprising experts in psychiatry, epidemiology and statistics selected 15 essential domains for inclusion in the final questionnaire., Results: The final selection resulted in a concise set of 22 questions. These questions cover factors such as age, sex, gender, ancestry, education, living arrangement, employment status, home location, relationship status, and history of medical and mental illness. Behavioral factors like physical activity, diet, smoking, alcohol and illicit drug use were also included, along with one question addressing family history of mental illness. Income was excluded due to high confounding and redundancy, while language was included as a measure of migration status., Conclusion: The recommendation and adoption of this harmonized tool for the assessment of demographic, clinical and behavioral data in mental health research can enhance data consistency and enable comparability across clinical trials., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship and/or publication of this article: M.B. is supported by a National Health and Medical Research Council (NHMRC) Senior Principal Research Fellowship and Leadership 3 Investigator grant (1156072 and 2017131).

Background: Ethnicity is known to be an important correlate of health outcomes, particularly during the COVID-19 pandemic, where some ethnic groups were shown to be at higher risk of infection and adverse outcomes. The recording of patients' ethnic groups in primary care can support research and efforts to achieve equity in service provision and outcomes; however, the coding of ethnicity is known to present complex challenges. We therefore set out to describe ethnicity coding in detail with a view to supporting the use of this data in a wide range of settings, as part of wider efforts to robustly describe and define methods of using administrative data., Methods: We describe the completeness and consistency of primary care ethnicity recording in the OpenSAFELY-TPP database, containing linked primary care and hospital records in > 25 million patients in England. We also compared the ethnic breakdown in OpenSAFELY-TPP with that of the 2021 UK census., Results: 78.2% of patients registered in OpenSAFELY-TPP on 1 January 2022 had their ethnicity recorded in primary care records, rising to 92.5% when supplemented with hospital data. The completeness of ethnicity recording was higher for women than for men. The rate of primary care ethnicity recording ranged from 77% in the South East of England to 82.2% in the West Midlands. Ethnicity recording rates were higher in patients with chronic or other serious health conditions. For each of the five broad ethnicity groups, primary care recorded ethnicity was within 2.9 percentage points of the population rate as recorded in the 2021 Census for England as a whole. For patients with multiple ethnicity records, 98.7% of the latest recorded ethnicities matched the most frequently coded ethnicity. Patients whose latest recorded ethnicity was categorised as Other were most likely to have a discordant ethnicity recording (32.2%)., Conclusions: Primary care ethnicity data in OpenSAFELY is present for over three quarters of all patients, and combined with data from other sources can achieve a high level of completeness. The overall distribution of ethnicities across all English OpenSAFELY-TPP practices was similar to the 2021 Census, with some regional variation. This report identifies the best available codelist for use in OpenSAFELY and similar electronic health record data., (© 2024. The Author(s).)
