RESUMO
Health professionals often need to work together to provide team-based care. With increasing healthcare complexities and manpower shortages, more health professionals are working in multiple, fluid teams instead of one stable team, to provide care to patients. However, there is currently no validated instrument to measure the quality of interprofessional collaboration in fluid teams. One approach is to assess team members' perceived level of teamness (qualities that make clinical teams effective). This study aimed to examine the validity evidence of using the Assessment for Collaborative Environment (ACE-15) in fluid teams and investigate if teamness varies among health professions and clinical settings. Content and response process validity were gathered through consulting experts and cognitive interviews, resulting in revisions to 11 of 15 items in ACE-15. Through exploratory factor analysis of 194 responses on the revised ACE-15, a 13-item instrument, ACE-13F, with strong validity evidence for use in fluid teams was developed. A two-factor fixed effect ANOVA model revealed that the clinical setting that health professionals work in has a significant impact on the level of teamness (F[3,170] = 6.15, p < .001, η2 = 0.09). ACE-13F can be used as a rapid instrument to measure interprofessional collaboration in fluid healthcare teams.

Racial and ethnic disparities in both healthcare management and delivery have been extensively documented in medical literature. For example, patients from non-White minority backgrounds in the United States have been found to experience worse clinical outcomes after surgery, to receive fewer surgical procedures, and to experience worse perioperative pain management compared with patients from non-minority backgrounds. A recent NIH-ACS Symposium on Surgical Disparities Research has identified an urgent need for research aimed at addressing and understanding these disparities. The present review summarizes existing literature describing perioperative pain disparities in children in the United States, as well as highlights the paucity of research in this domain. Specifically, there is a need for randomized control trials and health services research studying pediatric perioperative pain disparities. A multidisciplinary systems-based approach would help translate findings from scientific research to clinical practice and is a crucial step to ensuring all children of diverse backgrounds receive optimal perioperative care.

BACKGROUND: Cognitive decline is among the most feared treatment-related outcomes of older adults with cancer. The majority of older patients with breast cancer self-report cognitive problems during and after chemotherapy. Prior neuroimaging research has been performed mostly in younger patients with cancer. The purpose of this study was to evaluate longitudinal changes in brain volumes and cognition in older women with breast cancer receiving adjuvant chemotherapy. METHODS: Women aged ≥ 60 years with stage I-III breast cancer receiving adjuvant chemotherapy and age-matched and sex-matched healthy controls were enrolled. All participants underwent neuropsychological testing with the US National Institutes of Health (NIH) Toolbox for Cognition and brain magnetic resonance imaging (MRI) prior to chemotherapy, and again around one month after the last infusion of chemotherapy. Brain volumes were measured using Neuroreader™ software. Longitudinal changes in brain volumes and neuropsychological scores were analyzed utilizing linear mixed models. RESULTS: A total of 16 patients with breast cancer (mean age 67.0, SD 5.39 years) and 14 age-matched and sex-matched healthy controls (mean age 67.8, SD 5.24 years) were included: 7 patients received docetaxel and cyclophosphamide (TC) and 9 received chemotherapy regimens other than TC (non-TC). There were no significant differences in segmented brain volumes between the healthy control group and the chemotherapy group pre-chemotherapy (p > 0.05). Exploratory hypothesis generating analyses focusing on the effect of the chemotherapy regimen demonstrated that the TC group had greater volume reduction in the temporal lobe (change = - 0.26) compared to the non-TC group (change = 0.04, p for interaction = 0.02) and healthy controls (change = 0.08, p for interaction = 0.004). Similarly, the TC group had a decrease in oral reading recognition scores (change = - 6.94) compared to the non-TC group (change = - 1.21, p for interaction = 0.07) and healthy controls (change = 0.09, p for interaction = 0.02). CONCLUSIONS: There were no significant differences in segmented brain volumes between the healthy control group and the chemotherapy group; however, exploratory analyses demonstrated a reduction in both temporal lobe volume and oral reading recognition scores among patients on the TC regimen. These results suggest that different chemotherapy regimens may have differential effects on brain volume and cognition. Future, larger studies focusing on older adults with cancer on different treatment regimens are needed to confirm these findings. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01992432 .

PURPOSE: The purpose of this study was to evaluate longitudinal changes in brain gray matter density (GMD) before and after adjuvant chemotherapy in older women with breast cancer. METHODS: We recruited 16 women aged ≥ 60 years with stage I-III breast cancers receiving adjuvant chemotherapy (CT) and 15 age- and sex-matched healthy controls (HC). The CT group underwent brain MRI and the NIH Toolbox for Cognition testing prior to adjuvant chemotherapy (time point 1, TP1) and within 1 month after chemotherapy (time point 2, TP2). The HC group underwent the same assessments at matched intervals. GMD was evaluated with the voxel-based morphometry. RESULTS: The mean age was 67 years in the CT group and 68.5 years in the HC group. There was significant GMD reduction within the chemotherapy group from TP1 to TP2. Compared to the HC group, the CT group displayed statistically significantly greater GMD reductions from TP1 to TP2 in the brain regions involving the left anterior cingulate gyrus, right insula, and left middle temporal gyrus (pFWE(family-wise error)-corrected < 0.05). The baseline GMD in left insula was positively correlated with the baseline list-sorting working memory score in the HC group (pFWE-corrected < 0.05). No correlation was observed for the changes in GMD with the changes in cognitive testing scores from TP1 to TP2 (pFWE-corrected < 0.05). CONCLUSIONS: Our findings indicate that GMD reductions were associated with adjuvant chemotherapy in older women with breast cancer. Future studies are needed to understand the clinical significance of the neuroimaging findings. This study is registered on ClinicalTrials.gov (NCT01992432).

BACKGROUND: Rates of firearm violence (FV) surged during the COVID-19 pandemic. However, there is a paucity of data regarding older adults (OAs) (≥65 years old). This study aimed to evaluate patterns of FV against OAs before and after the COVID-19 pandemic, hypothesizing decreased firearm incidents, injuries, and deaths for OAs due to restricted social movement. METHODS: Retrospective (2016-2021) data for OAs were obtained from the Gun Violence Archive. The rate of FV was weighted per 10,000 OAs using annual population data from the United States Census Bureau. Mann-Whitney U tests were performed to compare annual firearm incidence rates, number of OAs killed, and number of OAs injured from 2016-2020 to 2021. RESULTS: From 944 OA-involved shootings, 842 died in 2021. The median total firearm incidents per month per 10,000 OAs decreased in 2021 vs 2016 (.65 vs .38, P < .001), 2017 (.63 vs .38, P < .001), 2018 (.61 vs .38, P < .001), 2019 (.39 vs .38, P = .003), and 2020 (.43 vs .38, P = .012). However, there was an increased median number of OAs killed in 2021 vs 2020 (.38 vs .38, P = .009), but no difference from 2016-2019 vs 2021 (all P > .05). The median number of firearm injuries decreased from 2017 to 2021 (.21 vs .19, P = .001) and 2020 to 2021 (.19 vs .19 P < .001). DISCUSSION: Firearm incidents involving OAs decreased in 2021 compared to pre-pandemic years; however, there was a slight increase in deaths compared to 2020. This may reflect increased social isolation; however, future research is needed to understand why this occurred.

PURPOSE: Rehabilitation professionals prescribe patients with suitable powered mobility aids (PMAs) based on patient characteristics, e.g., age and mobility. However, there is paucity of literature examining patient characteristics associated with PMA types in Asian contexts. This research aims to study (i) characteristics of Singapore PMA users and (ii) correlations between characteristics and two PMA types - motorised wheelchairs and powered scooters. It is hypothesised that patients' age, mobility status and medical conditions have correlations with PMA types. METHODOLOGY: A cross-sectional, retrospective study design was used to investigate characteristics of patients (age ≥ 21 years) at Tan Tock Seng Hospital Occupational Therapy Seating Clinic between 2017 and 2019. Comparisons of proportions of motorised wheelchair users versus powered scooter users based on characteristics were analysed using Chi-square test. Subsequently, statistically significant patient characteristics were selected for a multiple logistic regression. RESULTS: Among 352 patients, 21% and 79% were prescribed motorised wheelchairs and powered scooters, respectively. Patients aged 61-90 years were twice those aged 21-60 years. Males were double of females. Patients of (i) an older age, (ii) more ambulant, (iii) independent in transfers and (iv) in activities of daily living (ADLs), were more likely powered scooter users. Conversely, patients of (i) a younger age, (ii) less ambulant, (iii) require assistance in transfers and (iv) in ADLs were more likely motorised wheelchair users. Patients' gender and caregiver status showed no statistically significant correlations with PMA types. CONCLUSIONS: Rehabilitation professionals could consider patients' age, mobility status, transfer status and ADL status when prescribing PMA for Asian populations.Implications for rehabilitationGuide rehabilitation professionals in making clinical decisions on the type of powered mobility aid (PMA) to prescribe based on patients' characteristics.Aid in the development of future guidelines for rehabilitation professionals in prescription of PMAs.
RESUMO
PURPOSE: This study aims to determine whether older breast cancer survivors score lower on neuropsychological tests compared to matched non-cancer controls and to test the hypotheses that survivors who were APOE ε4 carriers would have the lowest cognitive performance but that smoking history would decrease the negative effect of ε4 on cognition. METHODS: Female breast cancer survivors who had been diagnosed and treated at age 60 or older and were 5-15-year survivors (N = 328) and age and education matched non-cancer controls (N = 162) were assessed at enrollment and at 8-, 16-, and 24-month follow-ups with standard neuropsychological and psychological assessments. Blood for APOE genotyping was collected, and smoking history was assessed at enrollment. Participants were purposely recruited so that approximately 50% had a history of treatment with chemotherapy or no chemotherapy and approximately 50% had a smoking history. RESULTS: After adjusting for age, cognitive reserve, depression, and fatigue, breast cancer survivors scored significantly lower on all domains of cognitive function. A significant two-way interaction demonstrated that the negative effect of ε4 on cognitive performance was stronger among survivors. A significant three-way interaction supported the hypothesis that smoking history had a protective effect on cognitive function in ε4 carriers that was more pronounced in the controls than the survivors. CONCLUSIONS: The results support the long-term cognitive impact of breast cancer diagnosis and treatments on older, disease-free survivors, particularly for ε4 carriers. The results also emphasize the importance of assessing smoking history when examining APOE and cognition and are an example of the complex interactions of age, genetics, health behaviors, and disease history in determining cognitive function. IMPLICATIONS FOR CANCER SURVIVORS: These results help explain why only a subset of breast cancer survivors appear to be vulnerable to cognitive problems.
RESUMO
INTRODUCTION: The relationship between cognitive function and frailty in older, long-term breast cancer survivors was examined. MATERIALS AND METHODS: Breast cancer survivors who were diagnosed and treated at 60 years of age or above and were 5-15 year disease-free survivors and non-cancer controls matched on age and education were evaluated with neuropsychological tests and the Comprehensive Geriatric Assessment which was used to assess frailty based on a deficit accumulation frailty index (DAFI). RESULTS: Unadjusted regression analyses revealed that cancer survivors scored significantly lower on the Language (P = 0.015), Attention, Processing Speed, Executive Function (APE) (P = 0.015), and Learning and Memory (LM) (P = 0.023) domains compared to controls. However, only the LM domain remained significantly different (P = 0.002) in the adjusted analysis. Survivors had significantly higher DAFI scores compared to controls (p = 0.006) and significantly more survivors were categorized as pre-frail or frail (35%) compared to controls (23%, P = 0.009). Increasing frailty scores were associated with worse cognitive performance across all domains (all Ps ≤ 0.004). For the LM domain, there was a significant interaction (P = 0.019) between DAFI score and survivorship vs control status. Survivors demonstrated a significant linear decline in LM scores as DAFI scores increased, whereas controls demonstrated comparable scores between the robust and pre-frail DAFI groups, demonstrating decline in the frailty group only. CONCLUSION: Older, long-term breast cancer survivors had lower cognitive performance and higher levels of frailty compared to controls. For the Learning and Memory domain, the decline in performance began in the pre-frail range for survivors, but not controls.

INTRODUCTION: Asia is the new and favored magnet of economic attention and foreign investments after it made an almost uneventful rebound from the depths of financial crisis of 2008/2009. Not many Western observers fully understand the diversity that is Asia other than perhaps its 2 growing economic giants of China and India. Indeed many smaller countries like Singapore and Malaysia in South East Asia along with Australia and Hong Kong (a Special Administrative Region within China) look to symbiotic relationships with these two economic giants. The purpose of this discussion paper is to examine the current issues related to the development and provision of occupational rehabilitation services in Singapore and Malaysia with a forward-looking view of how Asia's different developing societies could potentially benefit from better alignment of occupational rehabilitation practices and sharing of expertise through international collaboration and dialogue platforms. METHODS: Seven therapists and one physician who are frequently involved in occupational rehabilitation services in their home countries critically reviewed the current issues in Singapore and Malaysia which included analysis of the prevalence and cost of occupational injury; overview of workers' compensation system; current practices, obstacles, and challenges in providing occupational rehabilitation and return to work practices. They also offered opinions about how to improve the occupational rehabilitation programs of their two home countries. CONCLUSION: Even though Malaysia and Singapore are two different countries, in many ways their current provision of occupational rehabilitation services and the problems they face with are very similar. There is a lot of room for systemic improvements that require government support and action. Most prominently, the training of more healthcare professionals in the assessment and rehabilitation of the injured worker should be encouraged. There could be better liaison between the many stakeholders and more funding made available to develop resources and to jump start strategic programs. As these two countries are witnessing rapid economic growth, more resources should be allocated to establish holistic care of the injured workers emphasizing early interventions and prevention of chronic disabilities.

An insulin-like growth factor-1 receptor (IGF1R) variant in exon 6 (Arg-407-His) in Ashkenazi Jewish centenarians was previously found to be associated with reduced IGF1R activity. To further study this longevity associated IGF1R variant, we generated a novel mouse line carrying the R407H variant in exon 6 of the Igf1r gene by employing CRISPR/Cas9 genome editing technology. Here, we show that the Igf1r gene can be edited in mouse embryos by zygotic electroporation of Cas9 protein and a single-guide RNAs together with a single stranded oligonucleotide donor containing the desired key nucleotide changes at the Igf1r locus. Sequence analysis of F0 and F1 mice following targeted editing demonstrated the robustness of this approach in mice using CRISPR/Cas9 directed homologous recombination (HDR). Western blot analysis indicates that mice heterozygous for the variant have a significant decrease in IGF1R phosphorylation in various tissues, including skeletal muscle, compared to wildtype. In addition, depletion of IGF1R signaling specifically in skeletal muscle of progeroid Ercc1 -/Δ mice resulted in extended health span and median lifespan providing the rationale for long term lifespan studies in Igf1r hR407H variant mice. This mouse line will be a valuable genetic tool to help determine the impact of IGF1R signaling on aging and longevity. The CRISPR editing approach represents a prototype for generating additional longevity associated gene variant mouse lines to study relevance to human exceptional longevity.
RESUMO
As the number of older adults in the U.S. increases, so too will the incidence of cancer and cancer-related cognitive impairment (CRCI). However, the exact underlying biological mechanism for CRCI is not yet well understood. We utilized susceptibility-weighted imaging with quantitative susceptibility mapping, a non-invasive MRI-based technique, to assess longitudinal iron deposition in subcortical gray matter structures and evaluate its association with cognitive performance in women age 60+ with breast cancer receiving adjuvant chemotherapy and age-matched women without breast cancer as controls. Brain MRI scans and neurocognitive scores from the NIH Toolbox for Cognition were obtained before chemotherapy (time point 1) and within one month after the last infusion of chemotherapy for the patients and at matched intervals for the controls (time point 2). There were 14 patients age 60+ with breast cancer (mean age 66.3⯱â¯5.3â¯years) and 13 controls (mean age 68.2⯱â¯6.1â¯years) included in this study. Brain iron increased as age increased. There were no significant between- or within- group differences in neurocognitive scores or iron deposition at time point 1 or between time points 1 and 2 (pâ¯>â¯0.01). However, there was a negative correlation between iron in the globus pallidus and the fluid cognition composite scores in the control group at time point 1 (râ¯=â¯-0.71; pâ¯<â¯0.01), but not in the chemotherapy group. Baseline iron in the putamen was negatively associated with changes in the oral reading recognition scores in the control group (râ¯=â¯0.74, pâ¯<â¯0.01), but not in the chemotherapy group. Brain iron assessment did not indicate cancer or chemotherapy related short-term differences, yet some associations with cognition were observed. Studies with larger samples and longer follow-up intervals are warranted.

BACKGROUND: Return-to-work (RTW) programmes for injured workers have been prevalent in Western countries with established work injury management policies for decades. In recent years, more Asian countries have started to develop RTW programmes in the absence of work injury management policies. However, few studies have evaluated the effectiveness of RTW programmes in Asia. OBJECTIVE: Return-to-work coordination has been found to be an important facilitator in RTW programmes. This study seeks to determine the effectiveness of a Return-to-work coordinator (RTWC) model of care in facilitating early RTW for injured workers in Singapore. METHODS: A randomized controlled trial was used. 160 injured workers in a general hospital were randomly allocated to either control (receive usual hospital standard care) or intervention (assigned a RTWC) group. The RTWC closely supported RTW arrangements and proactively liaised with employers and healthcare professionals on RTW solutions for the injured workers. RESULTS: At three months post injury, workers in the intervention group RTW 10 days earlier than the control group, with a higher proportion of workers in the intervention group returning to modified jobs. There were no significant differences in the quality of life measures between the two groups. CONCLUSION: The addition of a RTWC into the hospital model of care is effective in facilitating early RTW for injured workers. This could be a potential model of care for injured workers in Asian countries where work injury management policies are not yet established.
