RESUMEN
STUDY QUESTION: Do children born to mothers with polycystic ovary syndrome (PCOS) have an adverse cardiometabolic profile including arterial stiffness at 9 years of age compared to other children? SUMMARY ANSWER: Children of mothers with PCOS did not have differing cardiometabolic outcomes than children without exposure. WHAT IS KNOWN ALREADY: While women with PCOS themselves have higher risk of cardiometabolic conditions such as obesity and diabetes, the evidence on intergenerational impact is unclear. Given in utero sequalae of PCOS (e.g. hyperandrogenism, insulin resistance), the increased risk could be to both boys and girls. STUDY DESIGN, SIZE, DURATION: The Upstate KIDS cohort is a population-based birth cohort established in 2008-2010 to prospectively study the impact of infertility treatment on children's health. After â¼10 years of follow-up, 446 mothers and their 556 children attended clinical visits to measure blood pressure (BP), heart rate, arterial stiffness by pulse wave velocity (PWV), mean arterial pressure, lipids, high-sensitivity C-reactive protein (hsCRP), hemoglobin A1c (HbA1c), and anthropometrics. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women self-reported ever diagnoses of PCOS â¼4 months after delivery of their children in 2008-2010. Linear regression models applying generalized estimating equations to account for correlation within twins were used to examine associations with each childhood cardiometabolic outcome. MAIN RESULTS AND THE ROLE OF CHANCE: In this cohort with women oversampled on infertility treatment, â¼14% of women reported a PCOS diagnosis (n = 61). We observed similarities in BP, heart rate, PWV, lipids, hsCRP, HbA1c, and anthropometry (P-values >0.05) among children born to mothers with and without PCOS. Associations did not differ by child sex. LIMITATIONS, REASONS FOR CAUTION: The sample size of women with PCOS precluded further separation of subgroups (e.g. by hirsutism). The population-based approach relied on self-reported diagnosis of maternal PCOS even though self-report has been found to be valid. Participants were predominantly non-Hispanic White and a high proportion were using fertility treatment due to the original design. Differences in cardiometabolic health may be apparent later in age, such as after puberty. WIDER IMPLICATIONS OF THE FINDINGS: Our results provide some reassurance that cardiometabolic factors do not differ in children of women with and without self-reported PCOS during pregnancy.

PRIMARY OBJECTIVE: Investigate the effects of land-based exercise-therapy on physical activity in people with knee osteoarthritis (KOA). DESIGN: Systematic review and meta-analysis of randomised or quasi-randomised trials investigating land-based exercise-therapy on physical activity, fitness, and general health in people with KOA. We updated a 2013 Cochrane review search on exercise-therapy for KOA in April 2021 and applied the Cochrane Risk-of-Bias Tool 1.0 to included articles. Standardised mean differences (SMDs) and 95% confidence intervals (CI) were calculated. GRADE was used to assess certainty of the evidence. RESULTS: Twenty-eight randomised controlled trials (2,789 participants) evaluating the effects of resistance-training (n = 10), walking (n = 6) and mixed-exercise programs (n = 7) were identified. Low to moderate certainty evidence indicated small increases in physical activity for exercise-therapy compared to non-exercise interventions in the short-term (SMD, 95% CI = 0.29, 0.09 to 0.50), but not the medium- (0.03, -0.11 to 0.18) or long-term (-0.06, -0.34 to 0.22). Low certainty evidence indicated large increases in physical activity for walking programs (0.53, 0.11 to 0.95) and mixed-exercise programs (0.67, 0.37 to 0.97) compared to non-exercise interventions in the short-term. Low certainty evidence indicated moderate and small increases in physical activity for resistance-training combined with education focused on pain coping skills and self-efficacy compared to education alone at medium-term follow-up (0.45, 0.19 to 0.71). CONCLUSION: Walking and mixed-exercise, but not resistance-training, may improve physical activity in people with KOA in the short-term. Combining resistance-training with education may increase physical activity in the medium-, but not the long-term, highlighting the potential importance of developing more effective longer-term interventions for people with KOA. Future studies evaluating land-based exercise-therapy are encouraged to include physical activity outcomes and longer-term follow-up to increase the certainty of evidence.

In March 2019, a mass shooting at two Christchurch mosques, livestreamed to Facebook, resulted in the deaths of 51 people. Psychologically, this served as a focusing event with high threat salience, shocking a country unused to gun violence despite its comparatively lax firearm legislation. The unprecedented reluctance by the New Zealand media to feature the shooter as a protagonist or even publish his name, concentrating instead on victims and societal issues, helped promote a sense of collective responsibility for change. This was strongly modeled by political leaders. Within weeks, new gun control laws were introduced with bipartisan support. We present this as a national case study, considering psychological and societal enablers for legislative reform in response to extreme gun violence. The shooting also raised the intractable problem of the internet allowing terrorists to promulgate violent content and extremist ideology with regulation in this area harder to achieve than gun control.
RESUMEN
STUDY QUESTION: Are toddlers conceived by fertility treatment at higher risk of failing a screening tool for autism spectrum disorders (ASD) than toddlers not conceived by treatment? SUMMARY ANSWER: Compared with children not conceived by infertility treatment, children conceived by any infertility treatment, ovulation induction with or without intrauterine insemination (OI/IUI), or assisted reproductive technologies (ART) appeared to have had higher odds of failing an ASD screening; however, results were inconclusive and need replication. WHAT IS KNOWN ALREADY: Although most of the studies which have examined risk of ASD after ART show no association, the results are mixed. Thus, further studies are needed to clarify this association. STUDY DESIGN SIZE, DURATION: The Upstate KIDS Study is a population-based, prospective cohort study of children born in New York State between 2008 and 2010. Children were screened for ASD using the Modified Checklist for Autism in Toddlers (M-CHAT) at ages 18 and 24 months. PARTICIPANTS/MATERIALS, SETTING, AND METHODS: The New York State live-birth registry was used to identify newborns conceived with and without fertility treatment with a 1:3 ratio, frequency matched on region of birth. At 18 and 24 months, 3183 and 3063 mothers, respectively, completed the M-CHAT questionnaire. The current analysis included 2586 singletons and 1296 twins with M-CHAT information at 18 and/or 24 months. Multivariable logistic regression with generalized estimating equations (GEE) was used to estimate odds ratios (aOR) and 95% confidence intervals (CI) after adjustment for covariates such as maternal age, education and plurality. MAIN RESULTS AND THE ROLE OF CHANCE: We found that 200 (5.2%) and 115 (3.0%) children failed the M-CHAT at 18 and 24 months, respectively. The associations between use of infertility treatment and failing the M-CHAT at 18 and/or 24 months were positive but inconclusive as they failed to exclude no association (18 months aOR 1.71, 95% CI: 0.81-3.61; 24 months aOR 1.78, 95% CI: 0.66-4.81; and both 18 and 24 months aOR 1.53, 95% CI: 0.78-2.99). The relationships between OI/IUI and ART with M-CHAT failure at 18 and/or 24 months were similar to those of using any fertility treatment. In vitro fertilization with intracytoplasmic sperm injection was not consistently positively or inversely associated with M-CHAT failure at each time point (18 months aOR 1.20, 95% CI: 0.51-2.83; 24 months aOR 0.93, 95% CI: 0.37-2.31; and both 18 and 24 months aOR 1.09, 95% CI: 0.50-2.60). LIMITATIONS REASONS FOR CAUTION: The M-CHAT is a screening tool used for ASD risk assessment, and therefore, M-CHAT failure does not indicate ASD diagnosis. In addition, we did not have power to detect associations of small magnitude. Finally, non-response to follow-up may bias the results. WIDER IMPLICATIONS OF THE FINDINGS: Despite lack of precision, the positive associations between ART and M-CHAT failure suggest that larger population-based studies with longer follow-up are needed.

Traumatic brain injury (TBI), resulting from either impact- or nonimpact blast-related mechanisms, is a devastating cause of death and disability. The cerebral blood vessels, which provide critical support for brain tissue in both health and disease, are commonly injured in TBI. However, little is known about how vessels respond to traumatic loading, particularly at rates relevant to blast. To better understand vessel responses to trauma, the objective of this project was to characterize the high-rate response of passive cerebral arteries. Rat middle cerebral arteries (MCAs) were isolated and subjected to high-rate deformation in the axial direction. Vessels were perfused at physiological pressures and stretched to failure at strain rates ranging from approximately 100 to 1300 s-1. Although both in vivo stiffness and failure stress increased significantly with strain rate, failure stretch did not depend on rate.
RESUMEN
Wild fish populations are currently experiencing unprecedented pressures, which are projected to intensify in the coming decades. Developing a thorough understanding of the influences of both biotic and abiotic factors on fish populations is a salient issue in contemporary fish conservation and management. During the 50th Anniversary Symposium of The Fisheries Society of the British Isles at the University of Exeter, UK, in July 2017, scientists from diverse research backgrounds gathered to discuss key topics under the broad umbrella of 'Understanding Fish Populations'. Below, the output of one such discussion group is detailed, focusing on tools used to investigate natural fish populations. Five main groups of approaches were identified: tagging and telemetry; molecular tools; survey tools; statistical and modelling tools; tissue analyses. The appraisal covered current challenges and potential solutions for each of these topics. In addition, three key themes were identified as applicable across all tool-based applications. These included data management, public engagement, and fisheries policy and governance. The continued innovation of tools and capacity to integrate interdisciplinary approaches into the future assessment and management of fish populations is highlighted as an important focus for the next 50 years of fisheries research.

During prosthetic joint infection (PJI), optimal surgical management with exchange of the device is sometimes impossible, especially in the elderly population. Thus, prolonged suppressive antibiotic therapy (PSAT) is the only option to prevent acute sepsis, but little is known about this strategy. We aimed to describe the characteristics, outcome and tolerance of PSAT in elderly patients with PJI. We performed a national cross-sectional cohort study of patients >75 years old and treated with PSAT for PJI. We evaluated the occurrence of events, which were defined as: (i) local or systemic progression of the infection (failure), (ii) death and (iii) discontinuation or switch of PSAT. A total of 136 patients were included, with a median age of 83 years [interquartile range (IQR) 81-88]. The predominant pathogen involved was Staphylococcus (62.1%) (Staphylococcus aureus in 41.7%). A single antimicrobial drug was prescribed in 96 cases (70.6%). There were 46 (33.8%) patients with an event: 25 (18%) with an adverse drug reaction leading to definitive discontinuation or switch of PSAT, 8 (5.9%) with progression of sepsis and 13 died (9.6%). Among patients under follow-up, the survival rate without an event at 2 years was 61% [95% confidence interval (CI): 51;74]. In the multivariate Cox analysis, patients with higher World Health Organization (WHO) score had an increased risk of an event [hazard ratio (HR) = 1.5, p = 0.014], whereas patients treated with beta-lactams are associated with less risk of events occurring (HR = 0.5, p = 0.048). In our cohort, PSAT could be an effective and safe option for PJI in the elderly.

PURPOSE: Follicular redox balance is likely to be important for embryo quality during in vitro fertilization (IVF), and the anti-oxidative high desity lipoprotein (HDL) particle is the sole lipoprotein measured in follicular fluid (FF). Therefore, we investigated FF HDL particle components as predictors of embryo quality during IVF. METHODS: Two research follicles collected from each participant were individually tracked, and 103 women having at least one developed embryo were included in the analysis. Concentrations of 15 non-cholesterol HDL particle components and 26 HDL-cholesterol (HDL-C) particle size subfractions were determined. Embryo quality was assessed for embryo cell number, embryo fragmentation, and embryo symmetry. Multivariable Poisson regression with a sandwich variance estimator was used to evaluate associations between HDL particle components and embryo quality, adjusted for covariates. RESULTS: Higher γ-tocopherol concentration was associated with less embryo fragmentation (relative risk [RR] = 4.43; 95 % confidence interval [CI] 1.78, 11.06), and higher apolipoprotein A-1 concentration was associated with full embryo symmetry (RR = 3.92; 95 % CI 1.56, 9.90). Higher concentrations of HDL-C subfractions in the large and medium particle size ranges were associated with poorer embryo quality. CONCLUSIONS: FF HDL lipophilic micronutrients and protein components, as well as HDL-C particle size, may be important predictors of embryo quality during IVF.

BACKGROUND: Personal health information, including diagnoses and hospital admissions, is routinely collected in administrative databases. Patients enrolling on clinical trials consent to separate collection and storage of their personal health information. We evaluated patient preferences for linking long-term data from administrative databases with clinical trials. METHODS: Adults with cancer attending outpatient clinics at 3 Ontario hospitals were surveyed about their willingness, when faced with the hypothetical scenario of participating in a clinical trial, to provide potentially identifying information such as initials and date of birth to facilitate long-term research access to normally deidentified publicly collected databases. RESULTS: Of 569 patients surveyed, 335 (59%) were women, 452 (79%) were white, 385 (68%) had a post-secondary education, and 386 (68%) had never participated in a clinical trial. Median age in the group was 59 years. Most participants (93%, cohort 1) would allow long-term access to their information and allow personal information to be used to match clinical trial with administrative data. At the time of clinical trial closure, two thirds of participants (68%, cohort 2) preferred to make additional clinical information available through linkage with administrative databases, and 8 (9%) preferred to have no further information made available to researchers. No significant differences were found in the subset of patients who were part of a clinical trial and those who had never participated (p = 0.65). INTERPRETATION: Almost all patients would allow a clinical trial research team to access their confidential information, providing a more comprehensive assessment of an intervention's long-term risks and benefits.
RESUMEN
STUDY QUESTION: Does early childhood growth from birth through to 3 years of age differ by mode of conception? SUMMARY ANSWER: Findings suggest early childhood growth was comparable for children irrespective of infertility treatment, but twins conceived with ovulation induction with or without intrauterine insemination (OI/IUI) were slightly smaller than twins conceived without treatment. WHAT IS KNOWN ALREADY: Although studies have found that babies conceived with infertility treatment are born lighter and earlier than infants conceived without treatment, little research especially for non-assisted reproductive technology (ART) treatments has focused on their continued growth during early childhood. STUDY DESIGN, SIZE, DURATION: Upstate KIDS recruited infants born (2008-2010) to resident upstate New York mothers. Infants were sampled based on birth certificate indication of infertility treatment; specifically, for every singleton conceived by infertility treatment, three singletons without infertility treatment were recruited and matched on region of birth. All multiple births irrespective of treatment were also recruited. Children were prospectively followed, returning questionnaires every 4-6 months until 3 years of age. In total, 3905 singletons, 1129 sets of multiples (96% of whom were twins) enrolled into the study. Analyses included 3440 (88%) singletons (969 conceived with treatment; specifically, 433 with ART and 535 with OI/IUI) and 991 (88%) sets of multiples (439 conceived with treatment; specifically 233 with ART and 206 with OI/IUI) with growth data available. PARTICIPANTS/MATERIALS, SETTING, METHODS: Mothers reported infertility treatment use at baseline and children's height and weight from pediatric visits. Self-reported use of ART was previously verified by linkage with the US Society for Assisted Reproductive Technology Clinic Outcome Reporting System (SART CORS) database. Mixed linear models with cubic splines accounting for age and age-gender interactions were used to estimate mean differences in growth from birth to 3 years by infertility treatment status and adjusting for maternal age, race, education, private insurance, smoking status during pregnancy, maternal pre-pregnancy and paternal body mass indices (BMI). MAIN RESULTS AND THE ROLE OF CHANCE: Compared with singletons conceived without treatment (n = 2471), singletons conceived by infertility treatment (433 by assisted reproductive technologies (ART), 535 by OI/IUI and 1 unknown specific type) did not differ in growth. Compared with twins not conceived with treatment (n = 1076), twins conceived with OI/IUI (n = 368) weighed slightly less over follow-up (122 g). They were also proportionally smaller for their length (-0.17 weight-for-length z-score units). No differences in mean size over the 3 years were observed for twins conceived by ART, though some evidence of rapid weight gain from birth to 4 months (adjusted OR 1.08; 95% CI: 1.00-1.16) suggestive of catch up growth was observed. LIMITATIONS, REASONS FOR CAUTION: Participants from upstate New York may not be representative of US infants. Although accounted for in statistical analysis, attrition during follow-up may have limited power to detect small differences. WIDER IMPLICATIONS OF THE FINDINGS: This study is the first to prospectively track the growth of children conceived with and without infertility treatment in the USA, including a substantial number of twins. Our findings are similar to what was previously observed in the ART literature outside of the states.

BACKGROUND: The prevalence of anxiety and mood disorders in adolescents is a growing public health concern worldwide. Given the high rates of drop-out and limited resources available in psychiatric settings, the importance of engaging adolescents in evidence-based treatments cannot be understated. The aim of the study was to determine the efficacy of motivational interviewing (MI), as a brief pre-treatment intervention, to enhance treatment engagement in a standard therapy setting (group cognitive behavioral therapy; gCBT) for adolescents with anxiety and mood disorders. METHOD: Ninety-six adolescents (13-18 years) with a principal diagnosis of an anxiety or mood disorder participated in a trial conducted at two publicly funded outpatient services. Participants were randomly assigned to individual MI for treatment engagement prior to gCBT (MI + gCBT), or to an individually administered active control (befriending) prior to gCBT (befriending + gCBT). Eight pairs of gCBT were run in parallel. Outcome measures were the mean number of gCBT sessions attended, treatment initiation, and ratings of readiness for treatment. RESULTS: Participants randomized to MI as a pretreatment intervention attended significantly more group therapy sessions compared to those in the active control condition. The MI group also demonstrated greater treatment initiation, and ratings of treatment readiness were significantly higher for those randomized to MI. CONCLUSIONS: MI, used as a pre-treatment intervention, enhanced group treatment engagement in adolescents diagnosed with anxiety and mood disorders compared to the active control condition. MI is a promising intervention to facilitate engagement in adolescent mental health settings.

Pimobendan is a benzimidazole-pyridazinone derivative, marketed as a racemic mixture for the management of canine heart failure. Pharmacokinetics of the enantiomers of pimobendan and its oral bioavailability have not been described in dogs. The aim of this study was to describe pharmacokinetics of three formulations of pimobendan in healthy dogs: the licensed capsule product, and novel liquid and intravenous formulations. A three-period, nested randomized two-treatment crossover design was used. Pimobendan was administered p.o. at 0.25 and i.v. at 0.125 mg/kg. Blood and plasma samples were analysed by liquid chromatography-mass spectrometry. Noncompartmental modelling was used to describe the pharmacokinetics. Parameters were compared between formulations using a general linear model. Bioequivalence of the oral formulations was tested using CI90 for AUC(0-∞) and Cmax . Bioavailability of pimobendan after oral dosing was 70%. Liquid and capsule formulations were bioequivalent only for AUC. The positive enantiomer of pimobendan (PE) had a larger volume of distribution than the negative enantiomer (NE) (281 ± 48 vs. 215 ± 68 mL/kg; P = 0.003) and a shorter half-life (21.7 vs. 29.9 min; P = 0.004). The NE was distributed more quickly than the PE into blood cells. Enantiomers of pimobendan have differing absorption, distribution and elimination. The pharmacokinetics of pimobendan in healthy dogs was described.

BACKGROUND: Demand for healthcare services threatens to overwhelm the Australian healthcare system. Public hospitals have the largest component of expenditure growth and as such represent the largest opportunity for efficiency gains. Utilisation of inpatient hospital beds and in particular those on general medical units has not been studied in Australia. AIM: To undertake a retrospective patient medical record review of 200 sequential admissions to the medical wards in two regional Tasmanian hospitals to determine the incidence of non-acute medical patient admission to the medical unit, and the subsequent days in hospital that were not required for medical reasons. The cost of these days was estimated. RESULTS: Sixteen patient admissions (8%) could not be justified on medical grounds. Forty-eight (24%) patient admissions had at least one day hospital day that could not be justified on medical grounds. Of the 1438 total bed days, 475 (33%) were for non-medical reasons. The estimated cost of those non-medical bed days for this cohort was $764 800. CONCLUSIONS: The incidence of non-acute medical admissions and non-acute medical bed days to the medical unit and associated cost was significant. Further research is needed to design alternative care provision for such patients particularly in regional Australia. The potential savings to the Australian healthcare system could be significant.

OBJECTIVE: People who have limited access to dental care may present to non-dental health practitioners for dental treatment and advice. This review synthesised the available evidence regarding the use of non-dental health practitioners for oral health problems and the services provided by non-dental health practitioners to manage such presentations. METHODS: PubMed and CINAHL databases were searched using key search terms to identify all relevant quantitative and qualitative English-language studies published between 1990 and March 2014. Snowballing techniques were then applied whereby the reference lists of retrieved articles were searched for other relevant citations. Grey literature was searched via Google using the same search terms to identify unpublished work and government reports. RESULTS: Of the 43 papers which met the review criteria, 25 papers reported on the use of non-dental health practitioners for oral health problems and 18 on dental care education and training for non-dental health practitioners. Four reports were located from the grey literature on the involvement of non-dental health practitioners in the management of oral health care. CONCLUSIONS: The review of literature showed that both children and adults utilise non-dental health practitioners for oral health problems. Despite this, Emergency Department medical staff, medical practitioners and pharmacists generally lacked training and knowledge in the maragement of oral health. Services from non-dental health practitioners mainly focussed on children. The literature on education and training for non-dental health practitioners was limited.

BACKGROUND: Respect for patient autonomy is a cornerstone of contemporary medical ethics and clinical practice. In its different shapes and forms (e.g. being informed, being engaged in discussions and decisions about medical care and being supported in developing healthcare preferences and choices), patient autonomy has been fostered by both paediatric and adult professional societies. The transition from paediatric to adult care creates a complex situation where autonomy for medical decisions shifts to the developing adolescent. More specific challenges to respect for autonomy may be experienced by young adults with cerebral palsy in the transition period where, for example, language and motor impairments may affect communication skills and this may be conflated with cognitive disability. AIM: To characterize perspectives towards autonomy in the healthcare context for young adults with cerebral palsy. METHOD: We carried out semi-structured interviews with 14 young adults (aged 18-25) with cerebral palsy. The audiotaped interviews were transcribed verbatim and analysed using a conventional thematic qualitative content analysis. RESULTS: Participants displayed a range of attitudes towards autonomy, suggesting that the value of autonomy is considered in light of competing values and of context. Testimonials from participants demonstrated that both contextual (e.g. ill-adapted health care, lack of specialized public transport) and relational (e.g. attitudes towards parental involvement in decision making) factors negatively or positively impact autonomy. CONCLUSION: We observed that there were four key elements interwoven in participants' characterization of autonomy: the coupling of decisional and physical autonomy, the influences of family and society on autonomy, the influence of healthcare professionals on autonomy and the need for preparation for autonomy.

INTRODUCTION: Physiological monitoring of soldiers can indicate combat readiness and performance. Despite demonstrated use of wearable devices for HR monitoring, commercial options lack desired military features. A newly developed OMNI monitor includes desired features such as long-range secure data transmission. This study investigated the accuracy of the OMNI to measure HR via accuracy of R-R interval duration relative to research-grade ECG and commercial products. METHODS: 54 healthy individuals (male/female=37/17, age=22.2±3.6 years, height=173.0±9.1 cm, weight=70.1±11.2 kg) completed a submaximal exercise test while wearing a reference ECG (Biopac) and a randomly assigned chest-based monitor (OMNI, Polar H10, Equivital EQ-02, Zephyr Bioharness 3). All participants also wore two wrist-based photoplethysmography (PPG) devices, Garmin fenix 6 and Empatica E4. Bland-Altman analyses of agreement, concordance correlation coefficient (CCC) and root-mean-squared error (RMSE) were used to determine accuracy of the OMNI and commercial devices relative to Biopac. Additionally, a linear mixed-effects model evaluated the effects of device and exercise intensity on agreement. RESULTS: Chest-based devices showed superior agreement with Biopac for measuring R-R interval compared with wrist-based ones in terms of mean bias, CCC and RMSE, with OMNI demonstrating the best scores on all metrics. Linear mixed-effects model showed no significant main or interaction effects for the chest-based devices. However, significant effects were found for Garmin and Empatica devices (p<0.001) as well as the interaction effects between both Garmin and Empatica and exercise intensity (p<0.001). CONCLUSIONS: Chest-based ECG devices are preferred to wrist-based PPG devices due to superior HR accuracy over a range of exercise intensities, with the OMNI device demonstrating equal, if not superior, performance to other commercial ECG monitors. Additionally, wrist-based PPG devices are significantly affected by exercise intensity as they underestimate HR at low intensities and overestimate HR at high intensities.
RESUMEN
Objective: To understand patient perceived acceptability of participating in a telehealth delivered group-based education and exercise-therapy program for knee osteoarthritis. Design: This qualitative study involved semi-structured, one-on-one interviews with knee osteoarthritis patients who have completed the Good Living with osteoArthritis from Denmark (GLA:D®) program via telehealth or in-person. Interviews were recorded, transcribed verbatim, coded, and analysed using an inductive content analysis approach, focusing on themes related to telehealth. Results: Nineteen participants [12 (63%) female, mean aged 62 years, range 49-72 years] were included. Eleven (58%) received GLA:D® via telehealth and 8 (42%) attended in-person sessions. Two overarching themes (6 sub-themes) related to telehealth perceived acceptability were identified: 1) Perceptions of telehealth acceptability was highly influenced by exposure. Individuals who had received telehealth considered it easy, convenient, and flexible, whereas telehealth was perceived to be inferior and misunderstood by those without exposure. 2) Telehealth participants reported similar program benefits to in-person participants, including reduced fear of pain and joint damage, changed beliefs in value of exercise, and stated improvements in pain and function. Conclusions: Telehealth delivery of group-based education and exercise-therapy for knee osteoarthritis was acceptable for people who had experienced it and provides similar benefits as in-person care for pain and beliefs about the safety and value of exercise. Wider implementation of telehealth group-based education and exercise-therapy may improve access to high value care for people with knee osteoarthritis.
RESUMEN
The problem of entrainment is central to circadian biology. In this regard, Drosophila has been an important model system. Owing to the simplicity of its nervous system and the availability of powerful genetic tools, the system has shed significant light on the molecular and neural underpinnings of entrainment. However, much remains to be learned regarding the molecular and physiological mechanisms underlying this important phenomenon. Under cyclic light/dark conditions, Drosophila melanogaster displays crepuscular patterns of locomotor activity with one peak anticipating dawn and the other anticipating dusk. These peaks are characterized through an estimation of their phase relative to the environmental light cycle and the extent of their anticipation of light transitions. In Drosophila chronobiology, estimations of phases are often subjective, and anticipation indices vary significantly between studies. Though there is increasing interest in building flexible analysis tools in the field, none incorporates objective measures of Drosophila activity peaks in combination with the analysis of fly activity/sleep in the same program. To this end, we have developed PHASE, a MATLAB-based program that is simple and easy to use and (i) supports the visualization and analysis of activity and sleep under entrainment, (ii) allows analysis of both activity and sleep parameters within user-defined windows within a diurnal cycle, (iii) uses a smoothing filter for the objective identification of peaks of activity (and therefore can be used to quantitatively characterize them), and (iv) offers a series of analyses for the assessment of behavioral anticipation of environmental transitions.
