Background Parkinson’s is a common progressive neurological condition characterized by motor and non-motor deficits. Physical activity and exercise can improve health, but many people with Parkinson’s (PwP) have trouble reaching the recommended dosage. Our recent literature review found improvements in exercise adherence with behavioural change interventions, but it remains unclear which are most effective. Further qualitative research and patient and public involvement has informed a novel behavioural change intervention to be tested alongside an existing exercise program. Objective To examine the feasibility of behavioural change techniques delivered alongside an exercise programme to improve physical activity, function, and self-efficacy in PwP (and study procedures) to inform a future pilot RCT trial. Methods A parallel-arm single blinded randomised feasibility study. Twenty participants with Parkinson’s (Hoehn and Yahr stage 1-3) will be recruited from a physiotherapy primary-care waiting list. Following written consent, and baseline assessment, the participants will be randomly allocated to the intervention (n=10) or the control group (n=10). Both groups will receive usual care, which includes a weekly program of a multidisciplinary education, a supervised exercise class and a prescribed home exercise program. The intervention group will receive additional behavioural change techniques, targeting behaviour regulation, belief about capabilities and social influences. Class and home exercise adherence, behavioural component uptake and adherence, and negative events will be recorded. Outcomes will include enrolment and maintenance rates, physical function, falls, physical activity, and exercise self-efficacy measured pre- and post- the 12-week program (in-person). Surveys will be used to compare experiences and satisfaction between groups. Exit interviews will be completed with the intervention group only, exploring their experience of the behavioural change techniques. Discussion The results will help inform a future pilot RCT, based on the intervention acceptability, consent rate, maintenance, and protocol integrity.

The benefits of exercise have been widely explored among people with Parkinson’s (PwP). Exercise can improve non-motor (fatigue, pain, sleep, etc.) and motor features (balance, muscle strength, gait speed, etc.), maintain function, as well as prevent disease progression. Although the benefits are well known, PwP continue to show difficulty adhering to physical activity and exercise. This study aims to explore motivation to exercise, support, and self-management needs among people with Parkinson’s, their family members, and physiotherapists. Purposeful and maximum-variation sampling methods (age, sex, geographical setting, and disease severity) were employed. PwP and family members were recruited through physiotherapy services and local support groups. Twelve semi-structured interviews with PwP and two group interviews, one with family members (n = 4) and one with physiotherapists (n = 5), were conducted. Interview guides were informed by patient–public input and a recent systematic review. Interviews were recorded, transcribed, and analysed using thematic analysis informed by the Grounded Theory methodology. Four common themes emerged: (1) The value of an intrinsic connection with exercise, for which there are challenges. A greater connection to exercise led to long-term adherence. (2) Adapting exercise to the needs and preferences of a person is essential. Preferred exercises and environments were mixed, with differences emerging between sexes. (3) Physiotherapists’ aim to only maintain physical function led to frustration. Limited self-management opportunities, stigma, and dehumanisation were discussed. (4) Non-motor symptoms, stigma, fear, and determination as well as apathy, pain, and low mood were discussed. Exercise provided physical, emotional, and social rewards. Supports are necessary; however, challenges arise when PwP’s motivations are mismatched to family members’ and physiotherapists’ goals. Co-created goals, tailored to their preferences, and exercise plans with supported self-management are recommended.

Physical activity and exercise can limit the development of sarcopenia in Parkinson's Disease. This review aims to evaluate the potential effects of behavioural change (BC) interventions on exercise self-efficacy and adherence in people with Parkinson's. We searched nine databases and included randomised and non-randomised studies reporting exercise self-efficacy, quality of life (QoL), physical function and/or exercise adherence. Two reviewers independently screened, data extracted, and assessed risk of bias and certainty of evidence. The interventions were mapped to the Theoretical Domains Framework. Eleven studies (n=901) were included. Four were randomised trials and risk of bias was mixed. Most interventions were multi-component, including education, behavioural techniques, and support groups. The most effective domains appear to be Behavioural regulation, Belief about Capabilities, Social influences, Reinforcement and Goals. Future research should examine multi-component BC interventions encompassing the five most effective TDF domains.

Introduction Falls are common among older people in long-term care facilities (LCFs). Falls lead to significant morbidity, mortality and reduced quality of life among residents. Fall prevention interventions have been shown to reduce falls in LCFs. However, this may not always translate to effectiveness in real-world situations. We will conduct a systematic review (SR) to identify the implementation strategies used in fall prevention interventions in LCF, describing the effectiveness of strategies in terms of key implementation outcomes and fall reduction. Methods and analysis The search will include scientific papers in electronic databases, including PubMed, CINAHL, Embase, PsycINFO, Scopus and Web of Science, and published theses. The SR will consider all original research that empirically evaluated or tested implementation strategies to support fall prevention interventions in LCF, published in English or Arabic between 1 January 2001 and 31 December 2021, where data are presented on the implementation strategy (eg, audit and feedback, champions) and/or implementation outcome (eg, fidelity). Clinical trials, quasi-experimental studies and quality improvement studies will be eligible for inclusion. Two researchers will complete abstract screening, data abstraction and quality assessments independently. The screening process will be presented using a Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram. Data will be extracted into a standardised table, including the country, year, authors, type of study, primary clinical outcome (falls rate and/or risk reduction as available), implementation strategy and implementation outcomes. Implementation strategies will be defined and categorised using the Expert Recommendation for Implementing Change Taxonomy. Implementation outcomes will be defined and categorised using the Implementation Outcomes Taxonomy, and clinical outcomes of the intervention effectiveness for falls preventions will be reported as formulated in each study, with a final narrative synthesis of data. Ethics and dissemination Ethical approval is not required for this study, and the results will be disseminated via peer-reviewed journals and presented at international conferences. PROSPERO registration number CRD42021239604.

Context: People with Parkinson's (PwP) have a higher tendency to engage in sedentary lifestyle behaviours and have lower physical activity levels compared to their healthy peers. Previous research has indicated that personal factors including poor outcome expectation and low self-efficacy are stronger predictors of exercise adherence than disease severity. Objectives: The purpose of this review is to synthesize the best available evidence on interventions that encompass self-management strategies to overcome barriers to exercise and improve self-efficacy and exercise adherence among PwP. Methods: The following databases will be searched using a comprehensive search strategy: EBSCO, Medline, Cinhal, Web of Science, PubMed, Embase, Scopus, Google Scholar and Cochrane Library from database inception to 2020. The title, abstract and full-text screening will be conducted by two independent reviewers. The Joanne Briggs Institute Checklist will be used to assess the quality of each included study. The quality of evidence will be reviewed using the GRADE criteria. Data will be extracted by two independent reviewers. The outcomes of interest will be self-efficacy outcomes and measures of exercise adherence. A systematic narrative synthesis will be conducted using a framework analysis, applying the Theoretical Domains Framework and Behaviour Change Wheel, producing findings focusing on practice-orientated outcomes. Presentation of data will include tables and text summarizing the characteristics and findings of the eligible studies. Discussion: The review will synthesize the best available evidence on interventions to enhance self-efficacy, improve quality of life, physical function, and ultimately improve exercise adherence among PwP and provide invaluable information for healthcare professionals. The findings of this review will be disseminated through publication in a peer-reviewed journal and presented at relevant conference proceedings. This review will make recommendations for appropriate self-management strategies for maximum effect and may have implications for policy and practice regarding enhancing self-efficacy and long-term exercise adherence among PwP.

Abstract Background An important consequence of population ageing has been the increasing number of older adults who live alone. According to TILDA data, older adults with the lowest levels of education tend to experience most social isolation and there is a strong association between living alone and loneliness. We sought to compare the cohort of patients open to the Integrated Care for Older Persons (ICPOP) team in a University Teaching Hospital serving a community area of approx. 300,000 population, to this national dataset. Methods A convenience sample of 174 patients who underwent comprehensive geriatric assessment via domiciliary visit between July 2021-May 2022 by was analysed. Data was anonymised and analysis was performed using SPSS v.27. Results The average age was 81.5 (±8.1) with 63% women in the sample. Eighty-five older adults i.e. 49% of the sample either lived alone or spent more than 21 hours alone per 24-hour period. Compared to those who live with someone, those who lived alone had higher rates of likely depression as determined by Geriatric Depression Score (6.6 vs 4.8 p=0.007). They were also likely to have less educational attainment, as determined by years spent in full time education (11.81 vs 10.42 42 p= 0.0016) and those living alone had overall less central heating in their homes than those not living alone (64/85 vs 81/89 p=0.0109). There were no significant differences in the rates of polypharmacy, falls, dementia and home ownership between groups. There were higher levels of frailty in the group living with someone than those living alone as determined by Clinical Frailty Scale (6.14 vs 5.23 p<0.001). Conclusion A high proportion of patients seen by our ICPOP team live alone and have complex care needs that require an innovative, multidisciplinary approach. Financial vulnerability in this group is likely to compound isolation and loneliness.

OBJECTIVE:To determine (1) the effectiveness of rehabilitation for chronic ankle instability as measured by the Star Excursion Balance Test (SEBT) and (2) the relative efficacy and the long-term effects of these rehabilitation interventions.DATA SOURCES:Ten electronic databases were searched (2009-2019).STUDY SELECTION:Included articles were randomized controlled trials in English investigating recreational athletes aged ≥18 years with chronic ankle instability. At least 1 functional rehabilitation intervention had to be included and the SEBT test (or the modified version) used as an outcome measure.DATA EXTRACTION:Two researchers (L.A., O.N.) extracted data regarding participant demographics; intervention characteristics; trial size; and results at baseline, postintervention, and at follow-up, where appropriate.DATA SYNTHESIS:A systematic review and narrative synthesis was conducted. Methodological quality of included studies was assessed using the Cochrane Risk of Bias Tool and the van Tulder scale. The review was registered with PROSPERO (ID: 164468). Ten studies (n=368), 2 high-quality, 1 moderate-quality, and 7 low-quality, were included in the review. Interventions included balance training, strength training, vibration training, and mixed training. Results suggest that rehabilitation of chronic ankle instability that includes wobble board exercises (average percentage change: 14.3%) and hip strengthening exercises (average percentage change: 12.8%) are most effective. Few studies compared different types of rehabilitation for chronic ankle instability. However, improvements on the SEBT suggest that a rehabilitation program focusing on wobble board training and hip strengthening performed 3 times weekly for 4-6 weeks is the optimal rehabilitation program to improve dynamic postural control in recreational athletes with chronic ankle instability.CONCLUSIONS:Few studies directly compared different rehabilitation interventions, and there was limited long-term follow-up; therefore, the relative efficacy of different rehabilitation programs remains unclear. However, it seems that rehabilitation of chronic ankle instability should include proprioceptive and strengthening exercises of relatively short duration.

The current dosage of zidovudine for children is 180 mg/m(2) every 6 h, To investigate whether a lower dosage was equally effective, human immunodeficiency virus (HIV)-infected children (3 months to 12 years) with mild to moderate symptoms were randomly assigned to receive either high-dose (180 mg/m(2)/dose) or low-dose (90 mg/m(2)/dose) zidovudine (double-blind), Treatments were compared with respect to neuropsychologic function, survival, clinical and laboratory evidence of disease progression, and safety and tolerance, Four hundred twenty-six HIV-infected children were enrolled; median time for receipt of study drug was 35 months, Zidovudine in either dose was well tolerated, with no difference in efficacy or tolerance by treatment group using any clinical or laboratory parameter, In children with mild to moderate disease, a reduction of zidovudine to 90 mg/m(2)/dose will result in substantial cost savings and should be the recommended dose.

Background: We evaluated data from prospectively identified twins to understand better the mechanisms and covariates of mother-to-infant transmission of human immunodeficiency virus (HIV).Methods: Using data obtained from an international collaboration and multivariate quasilikelihood modeling, we assessed concordance, birth order, route of delivery, and other factors for HIV infection in 115 prospectively studied twin pairs born to HIV-infected women. Actuarial methods were used to evaluate overall survival and survival free of acquired immunodeficiency syndrome for HIV-infected twins.Results: Infection with HIV occurred in 35% of vaginally delivered firstborn (A) twins, 16% of cesarean-delivered A twins, 15% of vaginally delivered second-born (B) twins, and 8% of cesarean-delivered B twins. In a multivariate model, the adjusted odds ratios for HIV infection were 11.8 (confidence interval: 3.1 to 45.3) for concordance of infection with the co-twin, 2.8 (confidence interval: 1.6 to 5.0) for A versus B twins, and 2.7 (confidence interval: 1.1 to 6.6) for vaginally delivered versus cesarean-delivered twins. Among A twins, 52% (lower confidence limit: 6%) of the transmission risk was related to vaginal delivery, Comparing vaginally delivered A twins (infants most exposed to vaginal mucus and blood) to cesarean-delivered B twins (infants least exposed), 76% (lower confidence limit: 48%) of the transmission risk was related to vaginal exposure. Infected B twins had slightly reduced Quetelet indexes and more rapid development of illnesses related to acquired immunodeficiency syndrome.Conclusions: These results indicate that HIV infection of B twins occurs predominantly in utero, whereas infection of A twins (and, by implication, singletons) occurs predominantly intrapartum, We propose that intrapartum transmission is responsible for the majority of pediatric HIV infections and that reducing exposure to HIV in the birth canal may reduce transmission of the virus from mother to infant.
