RESUMEN
Aims: To examine the associations of 1) absolute and normalized weakness cut-points, 2) collective weakness categories, and 3) changes in weakness status on future activities of daily living (ADL) limitations in older Americans. Methods: The analytic sample included 11,656 participants aged ≥65-years from the 2006-2018 waves of the Health and Retirement Study. ADL were self-reported. A handgrip dynamometer measured handgrip strength (HGS). Males were classified as weak if their HGS was <35.5-kg (absolute), <0.45-kg/kg (body mass normalized), or <1.05-kg/kg/m2 (body mass index (BMI) normalized); females were considered weak if their HGS was <20.0-kg, <0.337-kg/kg, or <0.79-kg/kg/m2. Collective weakness categorized those below 1, 2, or all 3 absolute and normalized cut-points. These collective categories were also used to classify observed changes in weakness status over time (onset, persistent, progressive, recovery). Results: Older Americans below absolute and normalized weakness cut-points had greater future ADL limitations odds: 1.34 (95% confidence interval (CI): 1.22-1.47) for absolute, 1.36 (CI: 1.24-1.50) for BMI normalized, and 1.56 (CI: 1.41-1.73) for body mass normalized. Persons below 1, 2, or 3 cut-points had 1.36 (CI: 1.19-1.55), 1.60 (CI: 1.41-1.80), and 1.70 (CI: 1.50-1.92) greater odds for future ADL limitations, respectively. Those in each changing weakness classification had greater future ADL limitation odds: 1.28 (CI: 1.01-1.62) for onset, 1.53 (CI: 1.22-1.92) for persistent, 1.72 (CI: 1.36-2.19) for progressive, and 1.34 (CI: 1.08-1.66) for recovery. Conclusions: The presence of weakness, regardless of cut-point and change in status over time, was associated with greater odds for future ADL limitations.
RESUMEN
OBJECTIVES: The management of aortic arch disease is complex. Open surgical management continues to evolve, and the introduction of endovascular repair is revolutionizing aortic arch surgery. Although these innovative techniques have generated the opportunity for better outcomes in select patients, they have also introduced confusion and uncertainty regarding best practices. METHODS: In New York, we developed a collaborative group, the New York Aortic Consortium, as a means of cross-linking knowledge and working together to better understand and treat aortic disease. In our meeting in May 2023, regional aortic experts and invited international experts discussed the contemporary management of aortic arch disease, differences in interpretation of the available literature and the integration of endovascular technology into disease management. We summarized the current state of aortic arch surgery in this review article. RESULTS: Approaches to aortic arch repair have evolved substantially, whether it be methods to reduce cerebral ischaemia, improve haemostasis, simplify future operations or expand options for high-risk patients with endovascular approaches. However, the transverse aortic arch remains challenging to repair. Among our collaborative group of cardiac/aortic surgeons, we discovered a wide disparity in our practice patterns and our management strategies of patients with aortic arch disease. CONCLUSIONS: It is important to build unique institutional expertise in the context of complex and evolving management of aortic arch disease with open surgery, endovascular repair and hybrid approaches, tailored to the risk profiles and anatomical specifics of individual patients.

BACKGROUND: Cannulation strategy in acute type A dissection (ATAD) varies widely without known gold standards. This study compared ATAD outcomes of axillary vs femoral artery cannulation in a large cohort from the International Registry of Acute Aortic Dissection (IRAD). METHODS: The study retrospectively reviewed 2145 patients from the IRAD Interventional Cohort (1996-2021) who underwent ATAD repair with axillary or femoral cannulation (axillary group: n = 1106 [52%]; femoral group: n = 1039 [48%]). End points included the following: early mortality; neurologic, respiratory, and renal complications; malperfusion; and tamponade. All outcomes are presented as axillary with respect to femoral. RESULTS: The proportion of patients younger than 70 years in both groups was similar (n = 1577 [74%]), as were bicuspid aortic valve, Marfan syndrome, and previous dissection. Patients with femoral cannulation had slightly more aortic insufficiency (408 [55%] vs 429 [60%]; P = .058) and coronary involvement (48 [8%] vs 70 [13%]; P = .022]. Patients with axillary cannulation underwent more total aortic arch (156 [15%] vs 106 [11%]; P = .02) and valve-sparing root replacements (220 [22%] vs 112 [12%]; P < .001). More patients with femoral cannulation underwent commissural resuspension (269 [30.9%] vs 324 [35.3%]; P = .05). Valve replacement rates were not different. The mean duration of cardiopulmonary bypass was longer in the femoral group (190 [149-237] minutes vs 196 [159-247] minutes; P = .037). In-hospital mortality was similar between the axillary (n = 165 [15%]) and femoral (n = 149 [14%]) groups (P = .7). Furthermore, there were no differences in stroke, visceral ischemia, tamponade, respiratory insufficiency, coma, or spinal cord ischemia. CONCLUSIONS: Axillary cannulation is associated with a more stable ATAD presentation, but it is a more extensive intervention compared with femoral cannulation. Both procedures have equivalent early mortality, stroke, tamponade, and malperfusion outcomes after statistical adjustment.

BACKGROUND: Transcatheter tricuspid valve replacement (TTVR) abolishes tricuspid regurgitation (TR) and has emerged as a definitive treatment for TR. OBJECTIVES: The purpose of this multicenter, observational study was to determine the clinical characteristics and short-term outcomes of patients with TR screened for TTVR. METHODS: Patients underwent TTVR screening at 7 centers on a compassionate-use basis. The primary endpoints were NYHA functional class and TR grade at 30-day follow-up. Secondary endpoints included all-cause mortality, heart failure hospitalization, technical success, and reasons for TTVR screening failure. RESULTS: A total of 149 patients (median age 79 years [Q1-Q3: 72-84 years], 54% women) underwent TTVR screening. The TTVR screening failure rate was 74%, mainly related to large tricuspid annular diameter. Patients undergoing TTVR (n = 38) had significant functional improvements (NYHA functional class I or II from 21% to 68%; P < 0.001), with TR ≤1+ in 97% at 30-day follow-up (P < 0.001 from baseline). Technical success was achieved in 91%, with no intraprocedural mortality or conversion to surgery. At 30-day follow-up, mortality was 8%, heart failure hospitalization 5%, major bleeding 18%, and reintervention 9%. Patients who failed screening for TTVR and subsequently underwent "bailout" transcatheter edge-to-edge repair (n = 26) had favorable outcomes (NYHA functional class I or II from 27% to 58%; P < 0.001), with TR ≤1+ in 43% at 30-day follow-up (P < 0.001 from baseline). CONCLUSIONS: This first real-world report of TTVR screening demonstrated a high screening failure rate, mainly related to large tricuspid annular diameter. Patients undergoing TTVR had superior TR reduction and symptom alleviation compared with bailout tricuspid transcatheter edge-to-edge repair, at the cost of greater procedural complications.

BACKGROUND: This exploratory analysis of the randomized controlled Aortic Surgery Cerebral Protection Evaluation CardioLink-3 trial sought to determine if cerebral oximetry desaturation during elective proximal arch repair is associated with detrimental postoperative neuroradiologic and neurofunctional outcomes. METHODS: Cerebral oximetry and pre- and postoperative brain magnetic resonance imaging data from 101 participants were analyzed. Oximetry data from the trial allocation groups were compared; the relationships between cerebral oximetry indices and new ischemic cerebral lesions on magnetic resonance imaging and neurologic outcomes were also evaluated. RESULTS: Total cerebral desaturation events (>20% decrease from baseline) on the left (median [interquartile range], 1 [1-3] vs 1.5 [0.5-3] with innominate and axillary cannulation; P = .80) were comparable to those on the right (1 [1-3] vs 1 [0-3]; P = .75) as were the total area under the curve of desaturation (left, P = .61; right, P = .84). Seventy patients had new ischemic lesions, among whom 36 had new severe lesions. Total desaturation events and area under the curve of desaturation were similar in patients with and without new ischemic lesions or severe lesions. The nadir regional cerebral saturation was lower on the left (49% [41-56]) than the right (53% [44-59]); left desaturation episodes were associated with lower postoperative cognitive test scores (P = .004). CONCLUSIONS: The innominate and axillary cannulation techniques for elective proximal arch repair with unilateral antegrade cerebral perfusion were associated with similar occurrences of cerebral oximetry desaturation and neither were associated with new ischemic lesions.

OBJECTIVE: We compared perioperative outcomes of patients with acute type A aortic dissection undergoing hemiarch (HA) versus extended arch (EA) repair with or without descending aortic intervention. METHODS: Nine hundred twenty-nine patients underwent acute type A aortic dissection repair (2002-2021, 9 centers) including open distal repair (HA) with or without additional EA repair. EA with intervention on the descending aorta (EAD) included elephant trunk, antegrade thoracic endovascular aortic replacement, or uncovered dissection stent. EA with no descending intervention (EAND), included unstented suture-only methods. Primary outcomes were in-hospital mortality, permanent neurologic deficit, computed tomography malperfusion resolution, and a composite. Multivariable logistic regression was also performed. RESULTS: Mean age was 66 ± 18 years, 30% (278 out of 929) were women, and HA was performed more frequently (75% [n = 695]) than EA (25% [n = 234]). EAD techniques included: dissection stent (39 out of 234 [17%]), thoracic endovascular aortic replacement (18 out of 234 [7.7%]), and elephant trunk (87 out of 234 [37%]). In-hospital mortality (EA: n = 49 [21%] and HA: n = 129 [19%]; P = .42), and neurological deficit (EA: n = 43 [18%] and HA: n = 121 [17%]; P = .74) were similar. EA was not independently associated with death (EA vs HA odds ratio, 1.09; 95% CI, 0.77-1.54; P = .63) or neurologic deficit (EA vs HA odds ratio, 0.85; 95% CI, 0.47-1.55; P = .59). Composite adverse events differed significantly (EA vs HA odds ratio, 1.47; 95% CI, 1.16-1.87; P = .001). Malperfusion resolved more frequently after EAD (EAD: n = 32 [80%], EAND: n = 18 [56%], HA: n = 71 [50%]; P = .004), although multivariable analysis was not significant (EAD vs HA odds ratio, 2.17; 95% CI, 0.83-5.66; P = .10). CONCLUSIONS: Extended arch interventions pose similar perioperative mortality and neurologic risks as Hemiarch. Descending aortic reinforcement may promote malperfusion restoration. Extended techniques should be approached with caution in acute dissection due to increased risk of adverse events.

BACKGROUND: Conduction disturbances and the need for permanent pacemaker (PPM) implantation remains a common complication for transcatheter aortic valve replacement (TAVR), particularly when self-expanding (SE) valves are used. AIMS: We compared in-hospital and 30-day rates of new PPM implantation between patients undergoing TAVR with SE valves using the conventional three-cusp coplanar implantation technique and the cusp-overlap technique. METHODS: We retrospectively compared patients without a pre-existing PPM who underwent a TAVR procedure with SE Evolut R or PRO valves using the cusp-overlap technique from July 2018 to September 2020 (n = 519) to patients who underwent TAVR using standard three-cusp technique from April 2016 to March 2017 (n = 128) in two high volume Canadian centers. RESULTS: There was no significant difference in baseline RBBB between the groups (10.4% vs. 13.2; p = 0.35). The rate of in-hospital new complete heart block (9.4% vs. 23.4%; p ≤ 0.001) and PPM implantation (8% vs. 21%; p ≤ 0.001) were significantly reduced when using the cusp-overlap technique. The incidence of new LBBB (30.4% vs. 29%; p = 0.73) was similar. At 30 days, the rates of new complete heart block (11% vs. 23%; p ≤ 0.001) and PPM implantation (10% vs. 21%, p ≤ 0.001) remained significantly lower in the cusp-overlap group, while the rate of new LBBB (35% vs. 30%; p = 0.73) was similar. CONCLUSION: Cusp-overlap approach offers several potential technical advantages compared to standard three-cusp view, and may result in lower PPM rates in TAVR with SE Evolut valve.

Objective: To compare the incidence of and adjusted hazards for serious and life-threatening morbidities among adults with traumatic spinal cord injury (TSCI) with and without type 2 diabetes (T2D). Participants and Methods: A retrospective longitudinal cohort study was conducted from September 1, 2022 to February 2, 2023, among privately insured beneficiaries if they had an International Classification of Diseases, 9th Revision or 10th Revision, Clinical Modification diagnostic code for TSCI (n=9081). Incidence estimates of serious and life-threatening morbidities, and more common secondary and long-term health conditions, were compared at 5 years of enrollment. Survival models were used to quantify unadjusted and adjusted hazard ratios for serious and life-threatening morbidities. Results: Adults living with TSCI and T2D had a higher incidence of all of the morbidities assessed as compared with nondiabetic adults with TSCI. Fully adjusted survival models reported that adults with TSCI and T2D had a greater hazard for most of the serious and life-threatening conditions assessed, including sepsis (hazard ratio [HR]: 1.65), myocardial infarction (HR: 1.63), osteomyelitis (HR: 1.9), and stroke or transient ischemic attack (HR: 1.59). Rates for comorbid and secondary conditions were higher for individuals with TSCI and T2D, such as pressure sores, urinary tract infections, and depression, even after controlling for sociodemographic and comorbid conditions. Conclusion: Adults living with TSCI and T2D have a significantly higher incidence of and risk of developing serious and life-threatening morbidities as compared with nondiabetic adults with TSCI.
RESUMEN
Physical activity of a sufficient amount and intensity is essential to health and the prevention of a sedentary lifestyle in all children as they transition into adolescence and adulthood. While fostering a fit lifestyle in all children can be challenging, it may be even more so for those with cerebral palsy (CP). Evidence suggests that bone and muscle health can improve with targeted exercise programs for children with CP. Yet, it is not clear how musculoskeletal improvements are sustained into adulthood. In this perspective, we introduce key ingredients and guidelines to promote bone and muscle health in ambulatory children with CP (GMFCS I-III), which could lay the foundation for sustained fitness and musculoskeletal health as they transition from childhood to adolescence and adulthood. First, one must consider crucial characteristics of the skeletal and muscular systems as well as key factors to augment bone and muscle integrity. Second, to build a better foundation, we must consider critical time periods and essential ingredients for programming. Finally, to foster the sustainability of a fit lifestyle, we must encourage commitment and self-initiated action while ensuring the attainment of skill acquisition and function. Thus, the overall objective of this perspective paper is to guide exercise programming and community implementation to truly alter lifelong fitness in persons with CP.
RESUMEN
BACKGROUND: On March 24, 2020, the Mexican Government established social distancing measures to address the outbreak of the COVID-19 pandemic. The resulting home confinement affected daily lifestyle habits such as eating, sleeping, and physical activity (PA). The objectives of this study were to determine changes in PA behaviors among Mexican women due to the COVID-19 pandemic and to assess potential factors associated with these changes. METHODS: This was a cross-sectional study based on an anonymous online questionnaire developed by the Task Force on Physical Activity for Persons with Disabilities (PAPD) within the International Society of Physical and Rehabilitation Medicine (ISPRM). Descriptive, quantitative statistics were used for data analysis. A Chi-squared (χ²) test was used to explore associations between dependent and independent variables. RESULTS: A total of 1882 surveys were completed. Among the respondents, 53.3% declared that their PA was reduced during the pandemic, 26.6% reported similar PA behavior, and 20.1% declared that their PA had increased during the pandemic. Lower PA behavior during the pandemic was associated with lower education levels, stricter pandemic constraints, obesity, and lower self-perceived functioning levels. A statistically significant association between poorer self-perceived mental health and decreased PA behaviors was also found. Respondents who were younger, self-perceived as unimpaired, not overweight, and whose income was not impacted by COVID-19 were associated with higher levels of reported physical and mental health. CONCLUSIONS: The study results identify disparities experienced in PA behavior during the COVID-19 pandemic among Mexican women and highlights the need for social support for PA participation.

INTRODUCTION: For children with cerebral palsy (CP), who are marginally ambulant, gross motor capacity peaks between 6 and 7 years of age with a subsequent clinical decline, impacting their ability to engage in physical activity. Active Strides-CP is a novel package of physiotherapy targeting body functions, activity and participation outcomes for children with bilateral CP. This study will compare Active Strides-CP to usual care in a multisite randomised waitlist-controlled trial. METHODS AND ANALYSIS: 150 children with bilateral CP (5-15 years), classified in Gross Motor Function Classification System (GMFCS) levels III and IV will be stratified (GMFCS III vs IV, age 5-10 years; 11-15 years and trial site) and randomised to receive either (1) 8 weeks of Active Strides-CP two times/week for 1.5 hours in clinic and one time/week for 1 hour alternating home visits and telehealth (total dose=32 hours) or (2) usual care. Active Strides-CP comprises functional electrical stimulation cycling, partial body weight support treadmill training, overground walking, adapted community cycling and goal-directed training. Outcomes will be measured at baseline, immediately post-intervention at 9 weeks primary endpoint and at 26 weeks post-baseline for retention. The primary outcome is the Gross Motor Function Measure-66. Secondary outcomes include habitual physical activity, cardiorespiratory fitness, walking speed and distance, frequency/involvement of community participation, mobility, goal attainment and quality of life. Analyses will follow standard principles for randomised controlled trials using two-group comparisons on all participants on an intention-to-treat basis. Comparisons between groups for primary and secondary outcomes will be conducted using regression models. A within-trial cost utility analysis will be performed. ETHICS AND DISSEMINATION: The Children's Health Queensland Hospital and Health Service, The University of Queensland, The University of Melbourne and Curtin University Human Research Ethics Committees have approved this study. Results will be disseminated as conference abstracts and presentations, peer-reviewed articles in scientific journals, and institution newsletters and media releases. TRIAL REGISTRATION NUMBER: ACTRN12621001133820.

BACKGROUND: There is little epidemiologic evidence on opioid prescription among adults with cerebral palsy (CP). AIM: To describe the population- and individual-level opioid prescription patterns for adults with versus without CP. METHOD: This retrospective cohort study used commercial claims (Optum's de-identified Clinformatics® Data Mart Database) from the USA from 01/01/2011-12/31/2017 from adults ≥ 18 years old with CP and matched adults without CP. For the population-level analysis, monthly estimates of opioid exposure were described for adults ≥ 18 years old with CP and matched adults without CP. For the individual-level analysis, group based trajectory modelling (GBTM) was used to identify groups of similar individual-level monthly opioid exposure patterns for adults with CP and matched adults without CP for 1-year starting from their first opioid exposure month. RESULTS: For the population-level, adults with (n = 13,929) versus without (n = 278,538) CP had a higher prevalence of opioid exposure (~ 12%, ~ 8%) and days supplied (median, ~ 23, ~17) monthly over 7 years. For the individual-level, there were 6 trajectory groups for CP (n = 2099) and 5 for non-CP (n = 10,361). Notably, 14% of CP (comprising 4 distinct trajectory groups) and 8% (comprising 3 distinct groups) of non-CP had variably high monthly opioid volume for extended periods; exposure was higher for CP. The remaining had low/absent opioid exposure trajectories; for CP (non-CP), 55.7% (63.3%) had nearly absent exposure and 30.4% (28.9%) had consistently low exposure to opioids. CONCLUSION: Adults with versus without CP were more likely to be exposed to opioids and for a longer duration, which may alter the risk-benefit balance of opioids.

BACKGROUND: Vision impairment (VI) affects approximately 1 in 28 Americans over the age of 40 and the prevalence increases sharply with age. However, experiencing vision loss with aging can be very different from aging with VI acquired earlier in life. People aging with VI may be at increased risk for diabetes due to environmental barriers in accessing health care, healthy food, and recreational resources that can facilitate positive health behaviors. OBJECTIVE: This study examined the relationship between neighborhood characteristics and incident type 2 diabetes mellitus (T2DM) among a cohort of 22,719 adults aging with VI. METHODS: Data are from Optum® Clinformatics® DataMart, a private administrative claims database (2008-2017). Individuals 18 years of age and older at the time of their initial VI diagnosis were eligible for analysis. VI was determined using vision impairment, low vision, and blindness codes (ICD-9-CM, ICD-10-CM). Covariates included age, sex, and comorbidities. Cox models estimated adjusted hazard ratios (HRs) for incident T2DM. Stratified models examined differences in those aging with (age 18-64) and aging into (age 65+) vision impairment. RESULTS: Residence in neighborhoods with greater intersection density (HR = 1.26) and high-speed roads (HR = 1.22) were associated with increased risk of T2DM among older adults with VI. Living in neighborhoods with broadband internet access (HR = 0.67), optical stores (HR = 0.62), supermarkets (HR = 0.78), and gyms/fitness centers (HR = 0.63) was associated with reduced risk of T2DM for both younger and older adults with VI. CONCLUSIONS: Findings emphasize the importance of neighborhood context for mitigating the adverse consequences of vision loss for health.

BACKGROUND: There is a large body of evidence linking muscular weakness, as determined by low grip strength, to a host of negative ageing-related health outcomes. Given these links, grip strength has been labelled a 'biomarker of aging'; and yet, the pathways connecting grip strength to negative health consequences are unclear. The objective of this study was to determine whether grip strength was associated with measures of DNA methylation (DNAm) age acceleration. METHODS: Middle age and older adults from the 2006 to 2008 waves of the Health and Retirement Study with 8-10 years of follow-up were included. Cross-sectional and longitudinal regression modelling was performed to examine the association between normalized grip strength (NGS) and three measures of DNAm age acceleration, adjusting for cell composition, sociodemographic variables and smoking. Longitudinal modelling was also completed to examine the association between change in absolute grip strength and DNAm age acceleration. The three DNAm clocks used for estimating age acceleration include the established DunedinPoAm, PhenoAge and GrimAge clocks. RESULTS: There was a robust and independent cross-sectional association between NGS and DNAm age acceleration for men using the DunedinPoAm (ß: -0.36; P < 0.001), PhenoAge (ß: -8.27; P = 0.01) and GrimAge (ß: -4.56; P = 0.01) clocks and for women using the DunedinPoAm (ß: -0.36; P < 0.001) and GrimAge (ß: -4.46; P = 0.01) clocks. There was also an independent longitudinal association between baseline NGS and DNAm age acceleration for men (ß: -0.26; P < 0.001) and women (ß: -0.36; P < 0.001) using the DunedinPoAm clock and for women only using the PhenoAge (ß: -8.20; P < 0.001) and GrimAge (ß: -5.91; P < 0.001) clocks. Longitudinal modelling revealed a robust association between change in grip strength from wave 1 to wave 3 was independently associated with PhenoAgeAA (ß: -0.13; 95% CI: -0.23, -0.03) and GrimAgeAA (ß: -0.07; 95% CI: -0.14, -0.01) in men only (both P < 0.05). CONCLUSIONS: Our findings provide some initial evidence of age acceleration among men and women with lower NGS and loss of strength over time. Future research is needed to understand the extent to which DNAm age mediates the association between grip strength and chronic disease, disability and mortality.

BACKGROUND: Acute kidney injury (AKI) after repair of type A acute aortic dissection (TAAAD) has been shown to affect both short- and long-term outcomes. This study aimed to validate the impact of postoperative AKI on in-hospital and long-term outcomes in a large population of dissection patients presenting to multinational aortic centers. Additionally, we assessed risk factors for AKI including surgical details. METHODS: Patients undergoing surgical repair for TAAAD enrolled in the International Registry of Acute Aortic Dissection database were evaluated to determine the incidence and risk factors for the development of AKI. RESULTS: A total of 3307 patients were identified. There were 761 (23%) patients with postoperative AKI (AKI group) vs 2546 patients without (77%, non-AKI group). The AKI group had a higher rate of in-hospital mortality (n = 193, 25.4% vs n = 122, 4.8% in the non-AKI group, P < .001). Additional postoperative complications were also more common in the AKI group including postoperative cerebrovascular accident, reexploration for bleeding, and prolonged ventilation. Independent baseline characteristics associated with AKI included a history of hypertension, diabetes, chronic kidney disease, evidence of malperfusion on presentation, distal extent of dissection to abdominal aorta, and longer cardiopulmonary bypass time. Kaplan-Meier survival curves revealed decreased 5-year survival among the AKI group (P < .001). CONCLUSIONS: AKI occurs commonly after TAAAD repair and is associated with a significantly increased risk of operative and long-term mortality. In this large study using the International Registry of Acute Aortic Dissection database, several factors were elucidated that may affect risk of AKI.
