Survey of awareness and attitudes to the management of fragility fractures among the membership of the Asia Pacific Orthopaedic Association.

A survey of awareness and attitudes to the management of fragility fractures among the membership of the Asia Pacific Orthopaedic Association conducted in 2022 found considerable variation in care across the region. A Call to Action is proposed to improve acute care, rehabilitation and secondary fracture prevention across Asia Pacific. PURPOSE: Fragility fractures impose a substantial burden on older people and their families, healthcare systems and national economies. The current incidence of hip and other fragility fractures across the Asia Pacific region is enormous and set to escalate rapidly in the coming decades. This publication describes findings of a survey of awareness and attitudes to the management of fragility fractures among the membership of the Asia Pacific Orthopaedic Association (APOA) conducted in 2022. METHODS: The survey was developed as a collaboration between the Asia Pacific Osteoporosis and Fragility Fracture Society and the Asia Pacific Fragility Fracture Alliance, and included questions relating to aspects of care upon presentation, during surgery and mobilisation, secondary fracture prevention, and access to specific services. RESULTS: In total, 521 APOA members completed the survey and marked variation in delivery of care was evident. Notable findings included: Fifty-nine percent of respondents indicated that analgesia was routinely initiated in transit (by paramedics) or within 30 minutes of arrival in the Emergency Department. One-quarter of respondents stated that more than 80% of their patients underwent surgery within 48 hours of admission. One-third of respondents considered non-hip, non-vertebral fractures to merit assessment of future fracture risk. One-third of respondents reported the presence of an Orthogeriatric Service in their hospital, and less than a quarter reported the presence of a Fracture Liaison Service. CONCLUSION: A Call to Action for all National Orthopaedic Associations affiliated with APOA is proposed to improve the care of fragility fracture patients across the region.

The recurrent deep intronic pseudoexon-inducing variant COL6A1 c.930+189C>T results in a consistently severe phenotype of COL6-related dystrophy: Towards clinical trial readiness for splice-modulating therapy.

Collagen VI-related dystrophies (COL6-RDs) manifest with a spectrum of clinical phenotypes, ranging from Ullrich congenital muscular dystrophy (UCMD), presenting with prominent congenital symptoms and characterised by progressive muscle weakness, joint contractures and respiratory insufficiency, to Bethlem muscular dystrophy, with milder symptoms typically recognised later and at times resembling a limb girdle muscular dystrophy, and intermediate phenotypes falling between UCMD and Bethlem muscular dystrophy. Despite clinical and immunohistochemical features highly suggestive of COL6-RD, some patients had remained without an identified causative variant in COL6A1, COL6A2 or COL6A3. With combined muscle RNA-sequencing and whole-genome sequencing we uncovered a recurrent, de novo deep intronic variant in intron 11 of COL6A1 (c.930+189C>T) that leads to a dominantly acting in-frame pseudoexon insertion. We subsequently identified and have characterised an international cohort of forty-four patients with this COL6A1 intron 11 causative variant, one of the most common recurrent causative variants in the collagen VI genes. Patients manifest a consistently severe phenotype characterised by a paucity of early symptoms followed by an accelerated progression to a severe form of UCMD, except for one patient with somatic mosaicism for this COL6A1 intron 11 variant who manifests a milder phenotype consistent with Bethlem muscular dystrophy. Characterisation of this individual provides a robust validation for the development of our pseudoexon skipping therapy. We have previously shown that splice-modulating antisense oligomers applied in vitro effectively decreased the abundance of the mutant pseudoexon-containing COL6A1 transcripts to levels comparable to the in vivo scenario of the somatic mosaicism shown here, indicating that this therapeutic approach carries significant translational promise for ameliorating the severe form of UCMD caused by this common recurrent COL6A1 causative variant to a Bethlem muscular dystrophy phenotype.

Staff Turnover Intention at Long-Term Care Facilities: Implications of Resident Aggression, Burnout, and Fatigue.

OBJECTIVES: Staff shortages and the high turnover rate of nursing assistants pose great challenges to long-term care. This study examined the effects of aggression from residents of long-term care facilities, burnout, and fatigue on staff turnover intention. The findings will help managers to devise effective measures to retain their staff. DESIGN: Cross-sectional descriptive study design. SETTING AND PARTICIPANTS: A total of 800 nursing assistants were recruited from 70 long-term care facilities using convenience sampling. METHODS: The participants were individually interviewed and provided information about their turnover intention, resident aggression witnessed and experienced, self-efficacy, neuroticism, burnout, fatigue, and personal and facility characteristics. RESULTS: Hierarchical multiple regression analysis revealed that the size and organizational practices of long-term care facilities were not associated with staff turnover intention. Staff who spent less time in the industry reported witnessing resident-to-resident aggression, experienced resident-to-staff aggression, reported high levels of burnout, had acute or chronic fatigue, and had low levels of inter-shift recovery were more likely than others to report a high turnover intention. CONCLUSIONS AND IMPLICATIONS: Staff turnover poses great challenges to staff, residents, and organizations. This study identified important factors that may help support staff in long-term care facilities. Specific measures, such as person-centered care to diminish resident aggression by addressing residents' unmet needs, work-directed programs to mitigate burnout and improve staff mental health, and flexible schedules to prevent fatigue should also be advocated to prevent staff turnover.

Implementation and assessment of an electronic clinical decision support tool to notify clinicians of critical hyperbilirubinemia in preterm neonates less than 35 weeks' gestation.

OBJECTIVES: Critical hyperbilirubinemia in preterm neonates, a condition requiring greater attention, is treated with phototherapy or exchange transfusion when bilirubin results exceed gestational age and age-specific medical decision levels (MDLs) to prevent bilirubin-induced neurologic damage. Conventional evaluation involves multiple manual steps and is poised to inconsistencies and delays. METHODS: We designed and implemented an electronic clinical decision support (CDS) tool to identify and alert neonatal intensive care unit clinicians of critical hyperbilirubinemia with a SmartZone alert. We evaluated the performance of our manual evaluation workflow, the accuracy of the electronic CDS tool, and the outcome of the electronic CDS tool to reduce the time to place orders for interventions. RESULTS: Among the 22 patients who met the criteria to have phototherapy ordered before implementing the electronic CDS tool, 20 (90%) had phototherapy ordered. Fourteen (70%) phototherapy orders were placed less than 24 hours, 4 phototherapy orders were placed 24 to 72 hours, and 2 orders were placed more than 72 hours after bilirubin results exceeded the corresponding MDLs. Among the 15 patients who met the criteria to have phototherapy ordered after implementing the electronic CDS tool, all (100%) received phototherapy orders, with 14 (93%) placed less than 24 hours and 1 order placed less than 48 hours. The electronic CDS tool identified all eligible patients correctly. The proportion of phototherapy ordered less than 24 hours increased from 70% to 93% after the implementation of the electronic CDS tool. CONCLUSIONS: The electronic CDS tool promoted more appropriate and timely intervention orders to manage critical hyperbilirubinemia in preterm neonates.

Trajectories of parent well-being in children with drug-resistant epilepsy.

OBJECTIVE: This longitudinal cohort study aimed to identify trajectories of parent well-being over the first 2 years after their child's evaluation for candidacy for epilepsy surgery, and to identify the baseline clinical and demographic characteristics associated with these trajectories. Parent well-being was based on parent depressive and anxiety symptoms and family resources (i.e., family mastery and social support). METHODS: Parents of 259 children with drug-resistant epilepsy (105 of whom eventually had surgery) were recruited from eight epilepsy centers across Canada at the time of their evaluation for epilepsy surgery candidacy. Participants were assessed at baseline and 6-month, 1-year, and 2-year follow-up. The trajectories of parents' depressive symptoms, anxiety symptoms, and family resources were jointly estimated using multigroup latent class growth models. RESULTS: The analyses identified three trajectories: an optimal-stable group with no/minimal depressive or anxiety symptoms, and high family resources that remained stable over time; a mild-decreasing-plateau group with mild depressive and anxiety symptoms that decreased over time then plateaued, and intermediate family resources that remained stable; and a moderate-decreasing group with moderate depressive and anxiety symptoms that decreased slightly, and low family resources that remained stable over time. Parents of children with higher health-related quality of life, fathers, and parents who had higher household income were more likely to have better trajectories of well-being. Treatment type was not associated with the trajectory groups, but parents whose children were seizure-free at the time of the last follow-up were more likely to have better trajectories (optimal-stable or mild-decreasing-plateau trajectories). SIGNIFICANCE: This study documented distinct trajectories of parent well-being, from the time of the child's evaluation for epilepsy surgery. Parents who present with anxiety and depressive symptoms and low family resources do not do well over time. They should be identified and offered supportive services early in their child's epilepsy treatment history.

Pre-Operative Predictors of Health-Related Quality of Life Two Years After Pediatric Epilepsy Surgery: A Prospective Cohort Study.

PURPOSE: Seizure freedom is an important predictor of health-related quality of life (HRQOL) after pediatric epilepsy surgery. This study aimed to identify the pre-operative predictors of HRQOL 2 years after epilepsy surgery in children with drug-resistant epilepsy. METHODS: This multicenter prospective cohort study assessed pre-operative predictors including child (demographics and clinical variables), caregiver (including caregiver depressive and anxiety symptoms) and family characteristics. HRQOL was assessed using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE)-55 pre-operatively and 2-years after surgery. Univariable linear regression analyses were done to identify significant preoperative predictors of HRQOL 2-years after surgery, followed by multivariable regression. RESULTS: Ninety-five children underwent surgery, mean age was 11.4 (SD=4.2) years, and 59 (62%) were male. Mean QOLCE scores were 57.4 (95%CI: 53.8, 61.0) pre-operatively and 65.6 (95%CI: 62.0, 69.1) after surgery. Univariable regression showed fewer anti-seizure medications (ß=-6.1 [95%CI: -11.2, -1.0], p = 0.019), older age at seizure onset (ß=1.6 [95%CI: 0.8, 2.4], p<0.001), higher pre-operative HRQOL (ß=0.7 [95%CI: 0.5, 0.8], p<0.001), higher family resources (ß=0.6 [95%CI: 0.3, 0.9], p<0.001), better family relationships (ß=1.7 [95%CI: 0.3, 3.1], p = 0.017) and lower family demands (ß=-0.9 [95%CI: -1.5, -0.4], p<0.001) were associated with higher HRQOL after surgery. Caregiver characteristics did not predict HRQOL after surgery (p>0.05). Multivariable regression showed older age at seizure onset (ß=4.6 [95%CI: 1.6, 7.6], p = 0.003) and higher pre-operative HRQOL (ß=10.2 [95%CI: 6.8, 13.6], p<0.001) were associated with higher HRQOL after surgery. CONCLUSION: This study underscores the importance of optimizing pre-operative HRQOL to maximize HRQOL outcome after pediatric epilepsy surgery.

Plasma Neurofilament Light Chain Is Elevated in Adaptor Protein Complex 4-Related Hereditary Spastic Paraplegia.

BACKGROUND: Adaptor protein complex 4-associated hereditary spastic paraplegia (AP-4-HSP) is caused by pathogenic biallelic variants in AP4B1, AP4M1, AP4E1, and AP4S1. OBJECTIVE: The aim was to explore blood markers of neuroaxonal damage in AP-4-HSP. METHODS: Plasma neurofilament light chain (pNfL) and glial fibrillary acidic protein (GFAP) levels were measured in samples from patients and age- and sex-matched controls (NfL: n = 46 vs. n = 46; GFAP: n = 14 vs. n = 21) using single-molecule array assays. Patients' phenotypes were systematically assessed using the AP-4-HSP natural history study questionnaires, the Spastic Paraplegia Rating Scale, and the SPATAX disability score. RESULTS: pNfL levels increased in AP-4-HSP patients, allowing differentiation from controls (Mann-Whitney U test: P = 3.0e-10; area under the curve = 0.87 with a 95% confidence interval of 0.80-0.94). Phenotypic cluster analyses revealed a subgroup of individuals with severe generalized-onset seizures and developmental stagnation, who showed differentially higher pNfL levels (Mann-Whitney U test between two identified clusters: P = 2.5e-6). Plasma GFAP levels were unchanged in patients with AP-4-HSP. CONCLUSIONS: pNfL is a potential disease marker in AP-4-HSP and can help differentiate between phenotypic subgroups. © 2023 International Parkinson and Movement Disorder Society.

Addressing the programming challenges of practical interferometric mesh based optical processors.

We demonstrate a novel mesh of Mach-Zehnder interferometers (MZIs) for programmable optical processors. We thoroughly analyze the benefits and drawbacks of previously known meshes and compare our newly proposed mesh with these prior architectures, highlighting its unique features and advantages. The proposed mesh, referred to as Bokun mesh, is an architecture that merges the attributes of the prior topologies Diamond and Clements. Similar to Diamond, Bokun provides diagonal paths passing through every individual MZI enabling direct phase monitoring. However, unlike Diamond and similar to Clements, Bokun maintains a minimum optical depth leading to better scalability. Providing the monitoring option, Bokun's programming is faster improving the total energy efficiency of the processor. The performance of Bokun mesh enabled by an optimal optical depth is also more resilient to the loss and fabrication imperfections compared to architectures with longer depth such as Reck and Diamond. Employing an efficient programming scheme, the proposed architecture improves energy efficiency by 83% maintaining the same computation accuracy for weight matrix changes at 2 kHz.

Real-World Use of AKI Biomarkers: A Quality Improvement Project Using Urinary Tissue Inhibitor Metalloprotease-2 and Insulin-Like Growth Factor Binding Protein 7 ([TIMP-2]*[IGFBP7]).

INTRODUCTION: Novel urinary biomarkers, including tissue inhibitor metalloprotease-2 and insulin-like growth factor binding protein 7 ([TIMP-2]*[IGFBP7]), have been developed to identify patients at risk for acute kidney injury (AKI). We investigated the "real-world" clinical utility of [TIMP-2]*[IGFBP7] in preventing AKI. METHODS: We performed a before and after single-center quality improvement study of intensive care unit (ICU) patients at risk for severe (KDIGO stage 2 or 3) AKI. In the prospective cohort, ICU providers were allowed to order [TIMP-2]*[IGFBP7] for patients at their discretion, then offered AKI practice recommendations based on the results. Outcomes were compared to a historical cohort in which biomarker values were not reported to clinical teams. RESULTS: There was no difference in 7-day progression to severe AKI between the prospective (n = 116) and historical cohorts (n = 63) when [TIMP-2]*[IGFBP7] ≥0.3 (24 [28%] versus 8 [21%], p = 0.38) despite more stage 1 AKI at time of biomarker measurement in the prospective cohort (58 [67%] versus 9 [23%], p < 0.001). In the prospective cohort, patients with higher [TIMP-2]*[IGFBP7] values were more likely to receive a nephrology consult. Early consultation (within 24 h of biomarker measurement, n = 20) had a nonsignificant trend toward net negative volume balance (-1,787 mL [6,716 mL] versus + 4,974 mL [15,540 mL]) and more diuretic use (19 [95%] versus 8 [80%]) and was associated with less severe AKI (9 [45%] versus 10 [100%], p = 0.004) and inpatient dialysis (2 [10%] versus 7 [70%], p = 0.002) compared to delayed consultation (n = 10). CONCLUSIONS: Despite the prospective cohort having more preexisting stage 1 AKI, there were equal rates of progression to severe AKI in the prospective and historical cohorts. In the setting of [TIMP-2]*[IGFBP7] reporting, there were more nephrology consults in response to elevated biomarker levels. Early nephrology consultation resulted in improved volume balance and favorable outcomes compared to delayed consultation.

A longitudinal cohort study of mediators of health-related quality of life after pediatric epilepsy surgery or medical treatment.

OBJECTIVES: The purpose of this longitudinal cohort study was to examine the variables that influence health-related quality of life (HRQOL) after epilepsy surgery in children. We examined whether treatment type (surgical vs medical therapy) and seizure control are related to other variables that have been shown to influence HRQOL, namely depressive symptoms in children with epilepsy or their parents, and the availability of family resources. METHODS: In total, 265 children with drug-resistant epilepsy were recruited from eight epilepsy centers across Canada at the time of their evaluation for candidacy for epilepsy surgery and were assessed at baseline, 6-month, 1-year, and 2-year follow-up. Parents completed the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE-55) and measures of family resources and depression; children completed depression inventories. Causal mediation analyses using natural effect models were used to evaluate the extent to which the relationship between treatment and HRQOL was explained by seizure control, child and parent depressive symptoms, and family resources. RESULTS: Overall, 111 children underwent surgery and 154 were treated with medical therapy only. The HRQOL scores of surgical patients were 3.4 points higher (95% confidence interval [CI]: -0.2, 7.0) relative to medical patients at the 2-year follow-up after adjusting for baseline covariates, with 66% of the effect of surgery attributed to seizure control. Child or parent depressive symptoms and family resources had negligible mediation effects between treatment and HRQOL. The effect of seizure control on HRQOL was not mediated by child or parent depressive symptoms, or by family resources. SIGNIFICANCE: The findings demonstrate that seizure control is on the causal pathway between epilepsy surgery and improved HRQOL in children with drug-resistant epilepsy. However, child and parent depressive symptoms and family resources were not significant mediators. The results highlight the importance of achieving seizure control to improve HRQOL.

Trajectory of Health-Related Quality of Life After Pediatric Epilepsy Surgery.

Importance: Health-related quality of life (HRQOL) is regarded as a key outcome for evaluating treatment efficacy. However, it is uncertain how HRQOL evolves after epilepsy surgery compared with medical therapy, such as whether it continues to improve over time, improves and then remains stable, or deteriorates after a period of time. Objective: To assess trajectory of HRQOL over 2 years in children with drug-resistant epilepsy (DRE) treated with surgery compared with medical therapy. Design, Setting, and Participants: Prospective cohort study assessing HRQOL longitudinally over 2 years. Participants were children recruited from 8 epilepsy centers in Canada from 2014 to 2019 with suspected DRE aged 4 to 18 years who were evaluated for surgery. Data were analyzed from May 2014 to December 2021. Exposures: Epilepsy surgery or medical therapy. Main Outcomes and Measures: HRQOL was measured using the Quality of Life in Childhood Epilepsy Questionnaire (QOLCE)-55. HRQOL and seizure frequency were assessed at baseline, 6-month, 1-year, and 2-year follow-ups. Clinical, parent, and family characteristics were assessed at baseline. A linear mixed model was used to evaluate HRQOL over time, adjusting for baseline clinical, parent, and family characteristics. Results: There were 111 surgical and 154 medical patients (mean [SD] age at baseline was 11.0 [4.1] years; 118 [45%] were female). At baseline, HRQOL was similar among surgical and medical patients. HRQOL of surgical patients was 3.0 (95% CI, -0.7 to 6.8) points higher at 6-month, 4.9 (95% CI, 0.7 to 9.1) points higher at 1-year, and 5.1 (95% CI, 0.7 to 9.5) points higher at 2-year follow-ups compared with medical patients. Surgical patients experienced greater improvements in social functioning relative to medical patients, but not for cognitive, emotional, and physical functioning. At 2-year follow-up, 72% of surgical patients were seizure-free, compared with 33% of medical patients. Seizure-free patients reported higher HRQOL than those who were not. Conclusions and Relevance: This study provided evidence on the association between epilepsy surgery and children's HRQOL, with improvement in HRQOL occurring within the first year and remaining stable 2 years after surgery. By demonstrating that surgery improved seizure freedom and HRQOL, which has downstream effects such as better educational attainment, reduced health care resource utilization, and health care cost, these findings suggest that the high costs of surgery are justified, and that improved access to epilepsy surgery is necessary.

Over-the-counter and direct-to-consumer testing for Group A streptococcus.

Over-the-counter (OTC) and direct-to-consumer (DTC) tests have been gaining popularity due to their potential to provide accurate and quick diagnostic results without any test order from healthcare professionals, while providing patients the opportunity to actively engage in their own health management. Group A streptococcus is a common transmissible pathogen that leads to acute pharyngitis. Accurate and timely diagnosis of Group A streptococcus pharyngitis is critical to urge patients to seek professional healthcare, to support antibiotic stewardship, to reduce disease transmission, and to prevent rare but potentially life-threatening complications such as acute rheumatic fever, rheumatic heart disease, and poststreptococcal glomerulonephritis. This review provides an overview for OTC and DTC testing in general, discusses the clinical utilization of Group A streptococcus testing, analyzes the limitations and challenges of current Group A streptococcus testing methodologies if developed into OTC or DTC tests. Finally, this review provides an outlook for future developments that would further improve healthcare outcomes.

Quality improvement initiatives in the care and prevention of fragility fractures in the Asia Pacific region.

This narrative review summarises ongoing challenges and progress in the care and prevention of fragility fractures across the Asia Pacific region since mid-2019. The approaches taken could inform development of national bone health improvement Road Maps to be implemented at scale during the United Nations 'Decade of Healthy Ageing'. PURPOSE: This narrative review summarises recent studies that characterise the burden of fragility fractures, current care gaps and quality improvement initiatives intended to improve the care and prevention of fragility fractures across the Asia Pacific region. METHODS: The review focuses on published studies, reports and quality improvement initiatives undertaken during the period July 2019 to May 2022. RESULTS: Epidemiological studies conducted in countries and regions throughout Asia Pacific highlight the current and projected increasing burden of fragility fractures. Recent studies and reports document a persistent and pervasive post-fracture care gap among people who have sustained fragility fractures. Global initiatives developed by the Fragility Fracture Network and International Osteoporosis Foundation have gained significant momentum in the Asia Pacific region, despite the disruption caused by the COVID-pandemic. The Asia Pacific Fragility Fracture Alliance has developed educational resources including a Hip Fracture Registry Toolbox and a Primary Care Physician Education Toolkit. The Asia Pacific Osteoporosis and Fragility Fractures Society-a new section of the Asia Pacific Orthopaedic Association-is working to engage orthopaedic surgeons across the region in the care and prevention of fragility fractures. The Asia Pacific Consortium on Osteoporosis developed a framework to support national clinical guidelines development groups. Considerable activity at the national level is evident in many countries across the region. CONCLUSION: Development and implementation of national Road Maps informed by the findings of this review are urgently required to respond to the epidemiological emergency posed by fragility fractures during the United Nations 'Decade of Healthy Ageing'.

An observational study evaluating the impact on prostate patient outcomes and experiences when radiation therapists use a standard grading system tool to assess and document treatment-related toxicities and interventions.

BACKGROUND/PURPOSE: Men undergoing radiation therapy (RT) treatment for prostate cancer (PC) often experience acute urinary, bowel, sexual, and hormonal toxicities. Timely screening, management, and documentation of these toxicities is an integral part of clinician practice, ensuring patients receive the care they require. Various screening tools, completed by either the patient or the clinician, are available, which allow clinicians to collect and respond to these toxicity outcomes; however there is a paucity of literature regarding the effective use and timing of these tools during RT treatment. This study aims to evaluate the feasibility of conducting comprehensive toxicity screening and symptom management using a toxicity screening tool in one of the busiest RT departments in Canada. Specifically, the use of a toxicity screening tool and its effect on the quality of toxicity documentation, operational impact, and patient reported outcomes (PRO). METHODS: 90 consented patients were allocated to either the structured or non-structured arm. Patients in the structured arm were assessed weekly by radiation therapists for 13 toxicities across four domains (bladder, bowel, hormonal, and sexual), using an in-house developed structured questionnaire, known as the Grid, to complete the National Cancer Institute's Common Toxicity Criteria for Adverse Events v3 (CTCAEv3). Patients in the non-structured arm were assessed and had free text clinical documentation charted according to current department policy. The Expanded Prostate Cancer Index Composite (EPIC), a PRO tool to evaluate patient function and bother after prostate cancer treatment, was completed by all study patients on a weekly basis. Statistical analysis compared documentation completeness, EPIC scores, patient satisfaction, and operational impact between study arms, as well as evaluated optimal timing of toxicity assessments. RESULTS: Assessment of the non-structured arm for completeness revealed an inconsistent and insufficient amount of documentation for the bladder and bowel domains. As for both the sexual and hormonal domains, documentation was largely absent. There was no difference in EPIC scores and patient satisfaction scores between the structured arm and the non-structured arm. Evaluation of the timing of PROs showed significant week to week change for the bladder and bowel toxicities, but not the sexual and hormonal toxicities. Finally, the use of the Grid revealed no significant impact on daily operations, only increasing average treatment times by seven seconds, and did not create any additional workload for the oncologists. CONCLUSIONS: Use of the Grid increased documentation completeness without negatively impacting clinical flow or operations, despite the fact that PROs were not improved. Based on EPIC PRO scores, bladder and bowel toxicities should be evaluated on a weekly basis during RT treatment, while sexual and hormonal toxicities need only be evaluated monthly.

An exercise cum cognitive-behavioral intervention for older adults with chronic pain: A cluster-randomized controlled trial.

OBJECTIVE: To examine the medium-term effects of a group intervention combining exercise and cognitive-behavioral strategies (EC) on older adults with chronic pain. METHOD: One hundred and fifty-two Hong Kong Chinese older adults with chronic pain affecting bones, muscles, and joints were randomized by clinic/social center to receive 10 weekly sessions of EC or pain education (control). The primary (pain intensity) and secondary outcomes (pain disability, pain self-efficacy, pain catastrophizing, pain coping, depressive symptoms, health-related quality of life, and hip and knee strength) were collected at baseline (T1), postintervention (T2), and 3- (T3) and 6-month follow-ups (T4). The trajectories of intervention effects were modeled by EC × time and EC × time2 interaction terms in mixed-effects regression. RESULTS: Significant EC × time and/or EC × time2 interactions were found for pain intensity, pain disability, self-efficacy, and catastrophizing, such that the treatment effect leveled off (pain disability) or diminished (pain intensity and catastrophizing) over time, or continued to increase in a linear fashion (self-efficacy). There was also a treatment main effect on hip/knee muscle strength. Group differences in favor of EC were observed up to 3-month follow-up for pain intensity (d = -0.51) and hip/knee muscle strength (d = 0.38), and up to 6-month follow-up for pain disability (d = -0.60) and self-efficacy (d = 0.52). No group difference was found for catastrophizing at any time point. No treatment effects were found for the other outcomes. CONCLUSION: Older people suffering from chronic pain can benefit from a program incorporating both cognitive-behavioral techniques and physical exercise.

Key Components for the Delivery of Palliative and End-of-Life Care in Care Homes in Hong Kong: A Modified Delphi Study.

Integrating the palliative care approach into care home service to address the complex care needs of older adults with frailty or advanced diseases has been increasingly recognized. However, such a service is underdeveloped in Hong Kong owing to socio-cultural and legal concerns. We adopted a modified Delphi study design to identify the key components for the delivery of palliative and end-of-life care in care home settings for the local context. It was an iterative staged method to assimilate views of experts in aged care, palliative care, and care home management. A multidisciplinary expert panel of 18 members consented to participate in the study. They rated their level of agreement with 61 candidate statements identified through a scoping review in two rounds of anonymous surveys. The steering group revised the statements in light of the survey findings. Eventually, the finalized list included 28 key statements concerning structure and process of care in seven domains, namely policy and infrastructure, education, assessment, symptom management, communication, care for dying patients, and family support. The findings of this study underscored concerns regarding the feasibility of statements devised at different levels of palliative care development. This list would be instrumental for regions where the development of palliative and end-of-life care services in care home setting is at an initial stage.

Development and Validation of a Liquid Chromatography Mass Spectrometry Method for Simultaneous Measurement of 25(OH)D3, epi-25(OH)D3, 25(OH)D2, Vitamin A, α-Tocopherol, and γ-Tocopherol.

OBJECTIVES: Fat-soluble vitamins are measured to identify deficiencies that may lead to rickets, osteomalacia, night blindness, and reversible motor and sensory neuropathies. We present a rapid liquid chromatography-mass spectrometry (LC-MS/MS) method that simultaneously measures 25-hydroxyvitamin D3 (25[OH]D3), epi-25(OH)D3, 25(OH)D2, vitamin A, α-tocopherol, and γ-tocopherol. METHODS: We mixed 100 µL serum with internal standard and extracted it by using supported liquid extraction plates. Reconstituted specimens were analyzed by LC-MS/MS with a 10-minute gradient. RESULTS: The method was linear, covering physiological levels with r2 > 0.99, and the total precision was less than 15% at all quality control levels. The lower limit of the measuring intervals for 25(OH)D3, epi-25(OH)D3, 25(OH)D2, vitamin A, α-tocopherol, and γ-tocopherol were 4 ng/mL, 4 ng/mL, 4 ng/mL, 1 µg/dL, 0.2 µg/mL, and 0.2 µg/mL, respectively, with coefficient of variation of 20% or less. Recoveries were between 92% and 111% for National Institute of Standards and Technology reference materials and 81% and 122% for spike-recovery studies. Comparison studies for vitamin D total, vitamin A, and α-tocopherol demonstrated slopes between 1.04 and 1.11 and r2 between 0.94 and 0.96. Minimal matrix effect was observed for all analytes. CONCLUSIONS: We developed and validated a rapid LC-MS/MS method for the simultaneous measurement of 25(OH)D3, epi-25(OH)D3, 25(OH)D2, vitamin A, α-tocopherol, and γ-tocopherol.
