Triple Crossed Flexure Pivot Based on a Zero Parasitic Center Shift Kinematic Design
Authors: Thalmann E. , Henein S. 
Published: January 2022

Abstract
Thanks to their absence of play, absence of contact friction and possible monolithic fabrication, flexure pivots offer advantages over traditional bearings in small-scale, high accuracy applications and environments where lubrication and wear debris are proscribed. However, they typically present a parasitic center shift that deteriorates their rotational guidance accuracy. Existing solutions addressing this issue have the drawbacks of reducing angular stroke, prohibiting planar design, or introducing overconstraints or underconstraints. This article presents a new triple crossed flexure pivot we have named TRIVOT whose kinematics theoretically nullify its parasitic center shift without overconstraints nor internal mobility. In the physical implementation, the center shift is non-zero but we show using the finite element method (FEM) that it is reduced by one order of magnitude in comparison to the widely used crossed flexure pivot (CFP). This allows to choose a crossing ratio of the flexures that either maximizes the angular stroke limit for given flexures or results in a compact planar design with the possibility of a remote center of compliance (RCC). Based on a pseudo-rigid-body model (PRBM), formulas for the rotational stiffness and angular stroke limit of the TRIVOT are derived, which are then validated by FEM. Finally, we show that a high support stiffness can be achieved based on a preliminary study for a mechanical watch time base application. We expect this new pivot to become a competitive alternative to the standard CFP for applications where high accuracy and compactness are required.
Media Coverage of the Paralympics: Recommendations for Sport Journalism Practice and Education
Authors: Antunovic Dunja , Bundon Andrea 
Published: January 2022

Researchers have extensively documented the issues in quantity and quality of media coverage of the Paralympic Games. The lack of coverage and stereotypical representations can be attributed to a variety of structural and cultural factors, notably including journalistic norms and values. This scholarly commentary proposes a reconsideration of journalistic values in order to argue that sports journalists have a professional responsibility to cover the Paralympics and issues of disability for at least three reasons: (a) The Paralympics are an elite-level, international sporting event and thus merit sport-focused coverage, (b) sport journalists have an ethical obligation to include diverse perspectives in reporting and to challenge stereotypes, and (c) sport is intertwined with social issues and requires contextualized reporting. The commentary concludes with recommendations for sport communication and journalism education.
Concurrent Validity of the Garmin Vivofit®4 to Accurately Record Step Count in Older Adults in Challenging Environments

Published: January 2022

There is little evidence of the concurrent validity of commercially available wrist-worn long battery life activity monitors to measure steps in older adults at slow speeds and with real-world challenges. Forty adults aged over 60 years performed a treadmill protocol at four speeds, a 50-m indoor circuit, and a 200-m outdoor circuit with environmental challenges while wearing a Garmin Vivofit®4, the activPAL3™, and a chest-worn camera angled at the feet. The Garmin Vivofit®4 showed high intraclass correlation coefficients2,1 (.98–.99) and low absolute percentage error rates (<2%) at the fastest treadmill speeds and the outdoor circuit. Step counts were underestimated at the slowest treadmill speed and the indoor circuit. The Garmin Vivofit®4 is accurate for older adults at higher walking speeds and during outdoor walking. However, it underestimates steps at slow speeds and when walking indoors with postural transitions.
The National Academy of Kinesiology: Its Founding, Focus, and Future
Authors: Cardinal Bradley J. 
Published: January 2022

This essay commemorates the National Academy of Kinesiology’s 90th anniversary meeting, even though the first meeting of fellows of an “[American] Academy of Physical Education” occurred in 1904, some 118 years ago. Clark W. Hetherington, Robert Tait McKenzie, William Burdick, Thomas A. Storey, and Jay B. Nash met in October 1926 to reignite the Academy of yesteryear. On December 31, 1930, just 14 months and 1 week into the Great Depression, they and 24 others formally launched what the Academy has become today. “Clearly, they were a bold, hearty, and optimistic group. Their determination, inspiration, and perspiration remain guiding lights for us to this day!” This essay aims to demystify and humanize the Academy by sharing stories of how it was formed and how it continues to inform all those working in kinesiology and related fields through its distinguished Fellows, one of whom is a Nobel Laureate.

IntroductionAs countries approach the UNAIDS 95-95-95 targets, there is a need for innovative and cost-saving HIV testing approaches that can increase testing coverage in hard-to-reach populations. The HIV Self-Testing Africa-Initiative distributed HIV self-test (HIVST) kits using unincentivised HIV testing counsellors across 31 public facilities in Malawi, South Africa, Zambia and Zimbabwe. HIVST was distributed either through secondary (partner’s use) distribution alone or primary (own use) and secondary distribution approaches.MethodsWe evaluated the costs of adding HIVST to existing HIV testing from the providers’ perspective in the 31 public health facilities across the four countries between 2018 and 2019. We combined expenditure analysis and bottom-up costing approaches. We also carried out time-and-motion studies on the counsellors to estimate the human resource costs of introducing and demonstrating how to use HIVST for primary and secondary use.ResultsA total of 41 720 kits were distributed during the analysis period, ranging from 1254 in Zimbabwe to 27 678 in Zambia. The cost per kit distributed through the primary distribution approach was $4.27 in Zambia and $9.24 in Zimbabwe. The cost per kit distributed through the secondary distribution approach ranged from $6.46 in Zambia to $13.42 in South Africa, with a wider variation in the average cost at facility-level. From the time-and-motion observations, the counsellors spent between 20% and 44% of the observed workday on HIVST. Overall, personnel and test kit costs were the main cost drivers.ConclusionThe average costs of distributing HIVST kits were comparable across the four countries in our analysis despite wide cost variability within countries. We recommend context-specific exploration of potential efficiency gains from these facility-level cost variations and demand creation activities to ensure continued affordability at scale.
Health-related quality of life in adults treated for paediatric acute lymphoblastic leukaemia: a cross-sectional and longitudinal cohort study

Published: January 2022

IntroductionAcute lymphoblastic leukaemia (ALL) is the most common form of cancer in children. Although treatment methods have improved and resulted in significant improvement of survival and reduction in late effects and late mortality risk, the health-related quality of life (HRQOL) of survivors might be affected. To introduce new interventions in clinical practice with the potential to support positive HRQOL outcomes, more knowledge is needed on how HRQOL in this group is constructed and stimulated. The purpose of this study is to investigate how HRQOL is affected in adults treated for paediatric ALL, in a long-term perspective and possible factors influencing this relationship.Methods and analysisThis cohort of young adult ALL survivors allows for investigations of factors influencing HRQOL outcomes on a national level. Eligible participants are obtained from the Swedish Childhood Cancer quality registry. Data collection includes both a follow-up of data collected in 2012 (n=224) and recruitment of new eligible participants to the cohort (n=601). The cohort will cover survivors of paediatric ALL, diagnosed between 1985 and 2007, at an age between 0 and 15 years. Data will be collected using validated, multidimensional, self-administered instruments, designed to measure HRQOL (SF-36), social support, sense of coherence and resilience.Ethics and disseminationThe study will be carried out in accordance with the ethics permit obtained from the Swedish ethics review authority (Dnr 2019-05181). Dissemination of study results will take place through research articles and reports to the national patient organisation and the national network for consultancy nurses for this target group and to the working group for the Swedish national long-term care programme for childhood cancer. Results will also reach practical application within the follow-up clinic for adult childhood cancer survivors at Sahlgrenska Hospital in Gothenburg.

Published: January 2022

IntroductionPsychosocial factors predict recovery in patients with spinal pain. Several of these factors are modifiable, such as depression and anxiety. However, primary care physiotherapists who typically manage these patients indicate that they do not feel sufficiently competent and equipped to address these factors optimally. We developed an eHealth intervention with a focus on pain education and behavioural activation to support physiotherapists in managing psychosocial factors in patients with spinal pain. This paper describes the protocol for a pragmatic randomised clinical trial, which evaluates the effectiveness of this eHealth intervention blended with physiotherapy compared with physiotherapy alone.Methods and analysisParticipants with non-specific low back pain and/or neck pain for at least 6 weeks who also have psychosocial risk factors associated with the development or maintenance of persistent pain will be recruited in a pragmatic multicentre cluster randomised clinical trial. The experimental intervention consists of physiotherapy blended with six online modules of pain education and behavioural activation. The control intervention consists of usual care physiotherapy. The primary outcomes are disability (Oswestry Disability Index for low back pain and Neck Disability Index for neck pain) and perceived effect (Global Perceived Effect). Outcomes will be assessed at baseline and at 2, 6 and 12 months after baseline. The results will be analysed using linear mixed models.Ethics and disseminationThe study is approved by the Medical Ethical Committee of VU Medical Center Amsterdam, The Netherlands (2017.286). Results will be reported in peer-reviewed journals, at national and international conferences, and in diverse media to share the findings with patients, clinicians and the public.Trial registration numberNL 5941; The Netherlands Trial Register.

IntroductionResearch suggests that current care for shoulder pain is not in line with the best available evidence. This project aims to assess the effectiveness, cost-effectiveness and the implementation of an evidence-based guideline for shoulder pain in general practice in Norway.Methods and analysisA stepped-wedge, cluster-randomised trial with a hybrid design assessing clinical effectiveness, cost-effectiveness and the effect of the implementation strategy of a guideline-based intervention in general practice. We will recruit at least 36 general practitioners (GPs) and randomise the time of cross-over from treatment as usual to the implemented intervention. The intervention includes an educational outreach visit to the GPs, a computerised decision tool for GPs and a self-management application for patients. We will measure outcomes at patient and GP levels using self-report questionnaires, focus group interviews and register based data. The primary outcome measure is the patient-reported Shoulder Pain and Disability Index measured at 12 weeks. Secondary outcomes include the EuroQol Quality of Life Measure (EQ5D-5L), direct and indirect costs, patient’s global perceived effect of treatment outcome, Pain Self-Efficacy and Brief Illness Perception Questionnaire. We will evaluate the implementation process with focus on adherence to guideline treatment. We will do a cost–minimisation analysis based on direct and selected indirect costs and a cost–utility analysis based on EQ5D-5L. We will use mixed effect models to analyse primary and secondary outcomes.Ethics and disseminationEthics approval was granted by the Regional Committee for Medical and Health Research Ethics-South East Norway (ref. no: 2019/104). Trial results will be submitted for publication in a peer-reviewed medical journal in accordance with Consolidated Standards of Reporting Trials.Trial registration numberNCT04806191.

ObjectivesTo examine the prevalence of mental health symptoms during the first surge of COVID-19 in the USA, and their associations with COVID-19-related emotional distress, health self-management and healthcare utilisation.DesignCross-sectional analysis of wave 3 (1–22 May 2020) survey data from the ongoing Chicago COVID-19 Comorbidities (C3) study.SettingSeven academic and community health centres in Chicago, Illinois.Participants565 adults aged 23–88 with one or more chronic conditions completing at least one prior C3 study wave.Primary and secondary outcome measuresClinically relevant anxiety and depressive symptoms as measured using Patient-Reported Outcomes Measurement Information System short forms. Self-reported emotional and health-related responses to COVID-19 were measured through a combination of single-item questions and validated measures.ResultsRates of anxiety and depressive symptoms were 14% (81/563) and 15% (84/563), respectively. Anxiety and depressive symptoms were then each separately associated with greater worry about contracting COVID-19 (relative risk (RR) 2.32, 95% CI 1.52 to 3.53; RR 1.67, 95% CI 1.10 to 2.54), greater stress (RR 4.93, 95% CI 3.20 to 7.59; RR 3.01, 95% CI 1.96 to 4.61) and loneliness (RR 3.82, 95% CI 2.21 to 6.60; RR 5.37, 95% CI 3.21 to 8.98), greater avoidance of the doctor (RR 1.62, 95% CI 1.06 to 2.49; RR 1.54, 95% CI 1.00 to 2.36) and difficulty managing health (least square means (LS Means) 6.09, 95% CI 5.25 to 6.92 vs 4.23, 95% CI 3.70 to 4.75; LS Means 5.85, 95% CI 5.04 to 6.65 vs 4.22, 95% CI 3.70 to 4.75) and medications (LS Means 3.71, 95% CI 2.98 to 4.43 vs 2.47, 95% CI 2.02 to 2.92) due to the pandemic.ConclusionsIdentifying and addressing mental health concerns may be an important factor to consider in COVID-19 prevention and management among high-risk medical populations.

PurposeObesity prevention is increasingly focused on early childhood, but toddlers have not been well-studied, and children born preterm are frequently excluded. The Play & Grow Cohort was established to investigate child growth in relation to parent-child interactions in mealtime and non-mealtime settings.ParticipantsBetween December 2017 and May 2019, 300 toddlers and primary caregivers were recruited from records of a large paediatric care provider in Columbus, Ohio, USA. This report describes recruitment of the cohort and outlines the data collection protocols for two toddler and two preschool-age visits. The first study visit coincided with enrolment and occurred when children (57% boys) were a mean (SD) calendar age of 18.2 (0.7) months.Findings to dateChildren in the cohort are diverse relative to gestational age at birth (16%, 28–31 completed weeks’ gestation; 21%, 32–36 weeks’ gestation; 63%, ≥37 weeks’ gestation) and race/ethnicity (8%, Hispanic; 35%, non-Hispanic black; 46%, non-Hispanic white). Caregivers enrolled in the cohort are primarily the child’s biological mother (93%) and are diverse in age (range 18–54 years), education (23%, high school or less; 20% graduate degree) and annual household income (27%, <US$20 000 24%, ≥US$90 000). Parent-child interactions were video-recorded during play in the laboratory at 18 months (n=299) and during play, reading and mealtime in the home (n=284) at 24 months. The preschool phase of the study was impacted by COVID-19. Parent-child interactions were video-recorded during play and mealtime at home at 36 months (n=141) and during a standardised buffet meal in the laboratory at 42 months (n=50). Caregivers unable to participate in face-to-face visits due to COVID-19 completed questionnaires.Future plansAssessment during middle childhood is being planned. Future visits will include anthropometric measurements and parent-child interactions at mealtime. School-based outcomes are additionally being considered.
Private sector delivery of maternal and newborn health care in low-income and middle-income countries: a scoping review protocol

Published: January 2022

IntroductionRecent studies have pointed to the substantial role of private health sector delivery of maternal and newborn health (MNH) care in low-/middle-income countries (LMICs). While this role has been partly documented, an evidence synthesis is missing. To analyse opportunities and challenges of private sector delivery of MNH care as they pertain to the new World Health Organization (WHO) strategy on engaging the private health service delivery sector through governance in mixed health systems, a more granular understanding of the private health sector’s role and extent in MNH delivery is imperative. We developed a scoping review protocol to map and conceptualise interventions that were explicitly designed and implemented by formal private health sector providers to deliver MNH care in mixed health systems.Methods and analysisThis protocol details our intended methodological and analytical approach following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews. Seven databases (Cumulative Index to Nursing and Allied Health, Excerpta Medica Database, International Bibliography of the Social Sciences, PubMed, ScienceDirect, Web of Science, WHO Institutional Repository for Information Sharing) and two websites will be searched for studies published between 1 January 2002 and 1 June 2021. For inclusion, quantitative and/or qualitative studies in LMICs must report at least one of the following outcomes: maternal morbidity or mortality; newborn morbidity or mortality; experience of care; use of formal private sector care during pregnancy, childbirth, and postpartum; and stillbirth. Analyses will synthesise the evidence base and gaps on private sector MNH service delivery interventions for each of the six governance behaviours.Ethics and disseminationEthical approval is not required. Findings will be used to develop a menu of private sector interventions for MNH care by governance behaviour. This study will be disseminated through a peer-reviewed publication, working groups, webinars and partners.
COVID-19 collateral damage—psychological burden and behavioural changes among older adults during the first outbreak in Stockholm, Sweden: a cross-sectional study

Published: January 2022

ObjectivesTo explore the indirect negative effects of COVID-19 restrictions (collateral damage) on the lives and health of older adults living in central Stockholm, and to characterise the sociodemographic profile of those with the highest susceptibility to this damage.DesignCross-sectional study.SettingDistrict of Kungsholmen in Stockholm, Sweden.ParticipantsOlder adults aged 68 years and above (n=1231) who participated in the ad hoc COVID-19-related phone questionnaire administered by trained staff between May and June 2020 and who had previously attended the regular follow-up assessment of the Swedish National study on Aging and Care in Kungsholmen (SNAC-K) during 2016–2019.Primary and secondary outcome measuresThree dimensions of collateral damage: psychological burden (feelings of worry, stress and loneliness), reductions in social and physical activities, and reductions in medical and social care use since the beginning of the pandemic. Logistic regression models were used to test the association between age, sex, education and living arrangement, and the risk of collateral damage.ResultsVast majority of participants adhered to the national public health recommendations, with over three-quarters practising self-isolation (n=928). Half of the sample reported psychological burden, 55.3% reported reductions in social or physical activity, and 11.3% reported decreased medical or social care use. Over three quarters of participants (77.8%) were affected by at least one of the three collateral damage dimensions. Female sex was the strongest sociodemographic predictor of both individual and co-occurring dimensions of collateral damage.ConclusionsCOVID-19 and its restrictions during the first half of 2020 had a negative effect on the health and lives of a majority of the elderly living in central Stockholm. Women were at a higher risk of these negative consequences. We emphasise the need for predefined, evidence-based interventions to support those who are most susceptible to these consequences, both during the pandemic and once the outbreak is overcome.
