RESUMEN

India's rich diversity encompasses individuals from varied geographical, cultural, and ethnic backgrounds. In the field of population genetics, comprehending the genetic diversity across distinct populations plays a crucial role. This study presents significant findings from genetic data obtained from the Sikkimese population of India. Autosomal markers were crucial for evaluating forensic parameters, with a combined paternity index of 1 × 109. Notably, Penta E emerged as a distinguishing marker for individual identification in the Sikkim population. Fst genetic distance values revealed insights into genetic isolation among different groups, enhancing our understanding of population dynamics in the central Himalayan region. The NJ-based phylogenetic tree highlighted close genetic relationships, of the Sikkim population with the Nepalese population surrounding neighbouring Himalayan populations providing glimpses into common ancestry. In summary, this study contributes valuable data to population genetics and underscores the importance of genetic variation in comprehending population dynamics and forensic applications.

RESUMEN

Throughout the COVID-19 pandemic New York City home health aides continuously provided care, including to patients actively infected or recovering from COVID-19. Analyzing survey data from 1316 aides, we examined factors associated with perceptions of how well their employer prepared them for COVID-19 and their self-reported availability for work (did they "call out" more than usual). Organizational work environment and COVID-19-related supports were predominant predictors of self-reported perceptions of preparedness. Worker characteristics and COVID-19-related stressors were predominant predictors of self-reported availability. Mental distress, satisfaction with employer communications, and satisfaction with supervisor instructions were significantly associated with both outcomes. The study uniquely describes self-reported perceptions of preparedness and availability as two separate worker outcomes potentially modifiable by different interventions. Better public health emergency training and adequate protective equipment may increase aides' perceived preparedness; more household supports could facilitate their availability. More effective employer communications and mental health initiatives could potentially improve both outcomes. Industry collaboration and systemic changes in federal, state, and local policies should enhance intervention impacts.

RESUMEN

BACKGROUND: Language concordance between health care practitioners and patients have recently been shown to lower the risk of adverse health events. Continuity of care also been shown to have the same impact. OBJECTIVE: The purpose of this paper is to examine the relative effectiveness of both continuity of care and language concordance as alternative or complementary interventions to improve health outcomes of people with limited English proficiency. DESIGN: A multivariable logistic regression model using rehospitalization as the dependent variable was built. The variable of interest was created to compare language concordance and continuity of care. PARTICIPANTS: The final sample included 22,103 patients from the New York City area between 2010 and 2015 who were non-English-speaking and admitted to their home health site following hospital discharge. MEASURES: The odds ratio (OR) average marginal effect (AME) of each included variable was calculated for model analysis. RESULTS: When compared with low continuity of care and high language concordance, high continuity of care and high language concordance significantly decreased readmissions (OR=0.71, 95% CI: 0.62-0.80, P<0.001, AME=-4.95%), along with high continuity of care and low language concordance (OR=0.80, 95% CI: 0.74-0.86, P<0.001, AME=-3.26%). Low continuity of care and high language concordance did not significantly impact readmissions (OR=1.04, 95% CI: 0.86-1.26, P=0.672, AME=0.64%). CONCLUSION: In the US home health system, enhancing continuity of care for those with language barriers may be helpful to address disparities and reduce hospital readmission rates.

RESUMEN

Depression is the leading cause of disability worldwide and its effects can be fatal, with over 800,000 people dying by suicide each year. Neuromodulatory treatments such as transcranial magnetic stimulation (TMS) are being used to treat depression. Despite its endorsement by two regulatory bodies: NICE (2016) and the FDA (2008), there are major questions about the treatment efficacy and biological mechanisms of TMS. Ahn et al.'s (2013) justified the use of TMS in a clinical context in an important study indicating that excitatory TMS increases reward responsiveness. A pseudo-replication of this study by Duprat et al., (2016) also found a similar effect of active TMS, but only with the addition of an exploratory covariate to the analyses-trait reward responsiveness. Here we replicate Ahn et al.'s (2013) key study, and to test the reliability of the effects, and their dependency on trait reward responsiveness as described by Duprat et al., (2016). Using excitatory and sham TMS, we tested volunteers using the probabilistic learning task to measure their reward responsiveness both before and after stimulation. We also examined affect (positive, negative) following stimulation. Irrespective of TMS, the task was shown to be sensitive to reward responsiveness. However, we did not show TMS to be effective in increasing reward responsiveness and we did not replicate Ahn et al., (2013) or Duprat et al., (2016)'s key findings for TMS efficacy, where we provide evidence favouring the null. Moreover, exploratory analyses suggested following active stimulation, positive affect was reduced. Given our findings, we question the basic effects, which support the use of TMS for depression, particularly considering potential deleterious effects of reduced positive affect in patients with depression.

RESUMEN

Home health aides provide care to homebound older adults and those with chronic conditions. Aides were less likely to receive COVID-19 vaccines when they became available. We examined aides' perspectives towards COVID-19 vaccination. Qualitative interviews were conducted with 56 home health aides at a large not-for-profit home care agency in New York City. Results suggested that aides' vaccination decisions were shaped by (1) information sources, beliefs, their health, and experiences providing care during COVID-19; (2) perceived susceptibility and severity of COVID-19; (3) perceived benefits of vaccination including protection from COVID-19, respect from colleagues and patients, and fulfillment of work-related requirements; (4) perceived barriers to vaccination including concerns about safety, efficacy, and side effects; and (5) cues to action including access to vaccination sites/appointments, vaccination mandates, question and answer sessions from trusted sources, and testimonials. Providing tailored information with support to address vaccination barriers could lead to improved vaccine uptake.

RESUMEN

BACKGROUND: Each year, approximately 100,000 individuals receive home health services after a stroke. Evidence has shown the benefits of home-based stroke rehabilitation, but little is known about resource-efficient ways to enhance its effectiveness, nor has anyone explored the value of leveraging low-cost home health aides (HHAs) to reinforce repetitive task training, a key component of home-based rehabilitation. We developed and piloted a Stroke Homehealth Aide Recovery Program (SHARP) that deployed specially trained HHAs as "peer coaches" to mentor frontline aides and help individuals recovering from stroke increase their mobility through greater adherence to repetitive exercise regimens. We assessed the feasibility of SHARP and its readiness for a full-scale randomized controlled trial (RCT). Specifically, we examined (1) the practicability of recruitment and randomization procedures, (2) program acceptability, (3) intervention fidelity, and (4) the performance of outcome measures. METHODS: This was a feasibility study including a pilot RCT. Target enrollment was 60 individuals receiving post-stroke home health services, who were randomized to SHARP + usual home care or usual care only. The protocol specified a 30-day intervention with four planned in-home coach visits, including one joint coach/physical therapist visit. The primary participant outcome was 60-day change in mobility, using the performance-based Timed Up and Go and 4-Meter Walk Gait Speed tests. Interviews with participants, coaches, physical therapists, and frontline aides provided acceptability data. Enrollment figures, visit tracking reports, and audio recordings provided intervention fidelity data. Mixed methods included thematic analysis of qualitative data and quantitative analysis of structured data to examine the intervention feasibility and performance of outcome measures. RESULTS: Achieving the 60-participant enrollment target required modifying participant eligibility criteria to accommodate a decline in the receipt of HHA services among individuals receiving home care after a stroke. This modification entailed intervention redesign. Acceptability was high among coaches and participants but lower among therapists and frontline aides. Intervention fidelity was mixed: 87% of intervention participants received all four planned coach visits; however, no joint coach/therapist visits occurred. Sixty-day follow-up retention was 78%. However, baseline and follow-up performance-based primary outcome mobility assessments could be completed for only 55% of participants. CONCLUSIONS: The trial was not feasible in its current form. Before progressing to a definitive trial, significant program redesign would be required to address issues affecting enrollment, coach/HHA/therapist coordination, and implementation of performance-based outcome measures. TRIAL REGISTRATION: ClinicalTrials.gov, NCT04840407 . Retrospectively registered on 9 April 2021.

RESUMEN

BACKGROUND: Home health care (HHC) is a leading form of home and community-based services for persons with dementia (PWD). Nurses are the primary providers of HHC; however, little is known of nursing care delivery and quality. OBJECTIVE: The objective of this study was to examine the association between continuity of nursing care in HHC and rehospitalization among PWD. RESEARCH DESIGN: This is a retrospective cohort study using multiple years (2010-2015) of HHC assessment, administrative, and human resources data from a large urban not-for-profit home health agency. SUBJECTS: This study included 23,886 PWD receiving HHC following a hospitalization. MEASURES: Continuity of nursing care was calculated using the Bice and Boxerman method, which considered the number of total visits, nurses, and visits from each nurse during an HHC episode. The outcome was all-cause rehospitalization during HHC. Risk-adjusted logistic regression was used for analysis. RESULTS: Approximately 24% of PWD were rehospitalized. The mean continuity of nursing care score was 0.56 (SD=0.33). Eight percent of PWD received each nursing visit from a different nurse (no continuity), and 26% received all visits from one nurse during an HHC episode (full continuity). Compared with those receiving high continuity of nursing care (third tertile), PWD receiving low (first tertile) or moderate (second tertile) continuity of nursing care had an adjusted odds ratio of 1.33 (95% confidence interval: 1.25-1.46) and 1.30 (95% confidence interval: 1.22-1.43), respectively, for being rehospitalized. CONCLUSIONS: Wide variations exist in continuity of nursing care to PWD. Consistency in nurse staff when providing HHC visits to PWD is critical for preventing rehospitalizations.

RESUMEN

BACKGROUND: Despite improvements in hypertension treatment in the United States, Black and Hispanic individuals experience poor blood pressure control and have worse hypertension-related outcomes compared to Whites. OBJECTIVE: The aim of the study was to determine the effect on hospitalization of supplementing usual home care (UHC) with two hypertension-focused transitional care interventions-one deploying nurse practitioners (NPs) and the other NPs plus health coaches. METHODS: We examined post hoc the effect of two hypertension-focused NP interventions on hospitalizations in the Community Transitions Intervention trial-a three-arm, randomized controlled trial comparing the effectiveness of (a) UHC with (b) UHC plus a 30-day NP transitional care intervention or (c) UHC plus NP plus 60-day health coach intervention. RESULTS: The study comprised 495 participants: mean age = 66 years; 57% female; 70% Black, non-Hispanic; 30% Hispanic. At the 3- and 12-month follow-up, all three groups showed a significant decrease in the average number of hospitalizations compared to baseline. The interventions were not significantly different from UHC. CONCLUSION: The results of this post hoc analysis show that, during the study period, decreases in hospitalizations in the intervention groups were comparable to those in UHC, and deploying NPs provided no detectable value added. Future research should focus on testing ways to optimize UHC services.

RESUMEN

Family caregivers often manage complex medical and nursing tasks (MNTs) for older adults transitioning from hospital to home. To explore caregivers' experiences managing MNTs in the postacute home health care (HHC) setting, we interviewed by phone 20 caregivers of older adults who received HHC following a hospitalization. Interviews were recorded, transcribed, and analyzed using directed content analysis. Caregivers highlighted the technical complexity and emotional impact of performing MNTs, as well as social (e.g., family, friends) and environmental (e.g., neighborhood, housing) resources they leveraged to meet the older adults' care needs. Caregivers also identified challenges coordinating care and services within HHC and the larger health care system. Caregiver engagement in the postacute HHC setting should incorporate tailored training and support, assessments of socioenvironmental context and resources, and facilitated navigation of the health care system. Future research should elucidate factors associated with successful collaborative relationships among HHC providers, older adults, and their caregivers in the postacute HHC setting.

RESUMEN

OBJECTIVES: This study compared the characteristics of Medicare beneficiaries who were hospitalized for heart failure (HF) and then discharged home who received home health care (HHC) to the characteristics of those who did not, and examined associations among HHC and readmission and mortality rates. BACKGROUND: After hospitalization for HF, some patients receive HHC. However, the use of HHC over time, the factors associated with its use, and the post-discharge outcomes after receiving it are not well studied. METHODS: This study used Get With The Guidelines-HF data, merged with Medicare fee-for-service claims. Propensity score matching and Cox proportional hazards models were used to evaluate the associations between HHC and post-discharge outcomes. RESULTS: From 2005 to 2015, 95,531 patients were admitted for HF, and 32,697 (34.2%) received HHC after discharge. The rate of HHC increased over time from 31.4% to 36.1% (p < 0.001). HHC recipients were older, more likely to be female, and had more comorbidities. HHC was associated with a higher risk of all-cause 30-day readmission (hazard ratio [HR]: 1.25; 95% confidence interval [CI]: 1.20 to 1.30), HF-specific 30-day readmission (HR: 1.20; 95% CI: 1.13 to 1.28), all-cause 90-day readmission (HR: 1.23; 95% CI: 1.19 to 1.26), HF-specific 90-day readmission (HR: 1.16; 95% CI: 1.11 to 1.22), and all-cause 30-and 90-day mortality, respectively (HR: 1.70; 95% CI: 1.56 to 1.86) and HR: 1.49; 95% CI: 1.41 to 1.57) compared to those who did not receive HHC. CONCLUSIONS: Use of HHC after HF hospitalization increased among Medicare beneficiaries. HHC recipients were older and sicker than non-HHC recipients. Although HHC was associated with a higher risk of readmissions and mortality, this finding should be interpreted cautiously, given the presence of unmeasured variables that could affect receipt of HHC. Research is needed to determine whether the results reflect appropriate health care use.

RESUMEN

BACKGROUND: Uncontrolled hypertension (HTN) is a leading modifiable stroke risk factor contributing to global stroke disparities. This study is unique in testing a transitional care model aimed at controlling HTN in black and Hispanic poststroke, home health patients, an understudied group. METHODS: A 3-arm randomized controlled trial design compared (i) usual home care (UHC), with (ii) UHC plus a 30-day nurse practitioner transitional care program, or (iii) UHC plus nurse practitioner plus a 60-day health coach program. The trial enrolled 495 black and Hispanic, English- and Spanish- speaking adults with uncontrolled systolic blood pressure (SBP ≥ 140 mm Hg) who had experienced a first-time or recurrent stroke or transient ischemic attack. The primary outcome was change in SBP from baseline to 3 and 12 months. RESULTS: Mean participant age was 67; 57.0% were female; 69.7% were black, non-Hispanic; and 30.3% were Hispanic. Three-month follow-up retention was 87%; 12-month retention was 81%. SBP declined 9-10 mm Hg from baseline to 12 months across all groups; the greatest decrease occurred between baseline and 3 months. The interventions demonstrated no relative advantage compared to UHC. CONCLUSION: The significant across-the-board SBP decreases suggest that UHC nurse/patient/physician interactions were the central component of SBP reduction and that additional efforts to lower recurrent stroke risk should test incremental improvements in usual care, not resource-intensive transitional care interventions. They also suggest the potential value of pragmatic home care programs as part of a broader strategy to overcome HTN treatment barriers and improve secondary stroke prevention globally. CLINICAL TRIALS REGISTRATION: Trial Number NCT01918891.

RESUMEN

BACKGROUND: There is little evidence to guide the care of over a million sepsis survivors following hospital discharge despite high rates of hospital readmission. OBJECTIVE: We examined whether early home health nursing (first visit within 2 days of hospital discharge and at least 1 additional visit in the first posthospital week) and early physician follow-up (an outpatient visit in the first posthospital week) reduce 30-day readmissions among Medicare sepsis survivors. DESIGN: A pragmatic, comparative effectiveness analysis of Medicare data from 2013 to 2014 using nonlinear instrumental variable analysis. SUBJECTS: Medicare beneficiaries in the 50 states and District of Columbia discharged alive after a sepsis hospitalization and received home health care. MEASURES: The outcomes, protocol parameters, and control variables were from Medicare administrative and claim files and the home health Outcome and Assessment Information Set (OASIS). The primary outcome was 30-day all-cause hospital readmission. RESULTS: Our sample consisted of 170,571 mostly non-Hispanic white (82.3%), female (57.5%), older adults (mean age, 76 y) with severe sepsis (86.9%) and a multitude of comorbid conditions and functional limitations. Among them, 44.7% received only the nursing protocol, 11.0% only the medical doctor protocol, 28.1% both protocols, and 16.2% neither. Although neither protocol by itself had a statistically significant effect on readmission, both together reduced the probability of 30-day all-cause readmission by 7 percentage points (P=0.006; 95% confidence interval=2, 12). CONCLUSIONS: Our findings suggest that, together, early postdischarge care by home health and medical providers can reduce hospital readmissions for sepsis survivors.

RESUMEN

Significant racial and ethnic disparities in stroke risk factors, occurrence, and outcomes persist in the USA. This article examines socio-economic and health disparities in a diverse, hypertensive sample of 495 post-stroke Black, non-Hispanic and Hispanic home health patients at risk of a recurrent stroke due to elevated systolic blood pressure (SBP), defined as SBP > 140 mmHg. The article, which analyzes cross-sectional data, focuses on correlates of patients' SBP-the leading modifiable cause of stroke-and physical function-a key stroke sequela and indicator of post-stroke quality of life. Of the 495 participants, 69.7% were Black, non-Hispanic, and 30.3% Hispanic. Black participants had significantly higher mean SBP than Hispanics. After controlling for multiple potential confounders/predictors, being Black was associated with a 3.55 mmHg elevation in SBP relative to being Hispanic. There were no significant Black/Hispanic differences in physical function measures. Seven independent variables significantly predicted better physical function: being male, younger, having fewer comorbidities, lower BMI, fewer depressive symptoms, higher health literacy, and current alcohol drinking (vs. abstinence). Our data provide a unique comparison of homebound Black and Hispanic stroke survivors at heightened risk of recurrent stroke absent targeted intervention. The finding of a significant Black/Hispanic disparity in SBP is striking in this narrowly defined home health care population all of whom are at risk for recurrent stroke. Priority should be given to culturally tailored interventions designed to link vulnerable home care patients to continuous, responsive hypertension care.

RESUMEN

Improved training and support are thought to improve retention among direct care workers. However, few studies have examined actual retention. This study examined satisfaction and retention among home health aides enrolled in the "Homecare Aide Workforce Initiative" (HAWI) at three New York agencies. Data included surveys of HAWI trainees and new hires and payroll data for HAWI graduates and others. Three months after hire, 91% of HAWI hires reported they were "very satisfied" or "satisfied" with the job; 57% reported they were "not at all likely" to leave their job in the coming year. At 365 days, 60% were still working. In logistic regression, the odds of being retained at 3, 6, and 12 months were significantly higher among HAWI graduates than non-HAWI new hires. Although not a randomized trial, the study demonstrates an association between participation in an innovative entry-level workforce program and superior 3-, 6-, and 12-month retention.

RESUMEN

The analysis of neoantigen-specific CD8+ T cells in tumour-bearing individuals is challenging due to the small pool of tumour antigen-specific T cells. Here we show that mass cytometry with multiplex combinatorial tetramer staining can identify and characterize neoantigen-specific CD8+ T cells in mice bearing T3 methylcholanthrene-induced sarcomas that are susceptible to checkpoint blockade immunotherapy. Among 81 candidate antigens tested, we identify T cells restricted to two known neoantigens simultaneously in tumours, spleens and lymph nodes in tumour-bearing mice. High-dimensional phenotypic profiling reveals that antigen-specific, tumour-infiltrating T cells are highly heterogeneous. We further show that neoantigen-specific T cells display a different phenotypic profile in mice treated with anti-CTLA-4 or anti-PD-1 immunotherapy, whereas their peripheral counterparts are not affected by the treatments. Our results provide insights into the nature of neoantigen-specific T cells and the effects of checkpoint blockade immunotherapy.Immune checkpoint blockade (ICB) therapies can unleash anti-tumour T-cell responses. Here the authors show, by integrating MHC tetramer multiplexing, mass cytometry and high-dimensional analyses, that neoantigen-specific, tumour-infiltrating T cells are highly heterogeneous and are subjected to ICB modulations.

RESUMEN

OBJECTIVE: To compare the effectiveness of two "treatments"-early, intensive home health nursing and physician follow-up within a week-versus less intense and later postacute care in reducing readmissions among heart failure (HF) patients discharged to home health care. DATA SOURCES: National Medicare administrative, claims, and patient assessment data. STUDY DESIGN: Patients with a full week of potential exposure to the treatments were followed for 30 days to determine exposure status, 30-day all-cause hospital readmission, other health care use, and mortality. An extension of instrumental variables methods for nonlinear statistical models corrects for nonrandom selection of patients into treatment categories. Our instruments are the index hospital's rate of early aftercare for non-HF patients and hospital discharge day of the week. DATA EXTRACTION METHODS: All hospitalizations for a HF principal diagnosis with discharge to home health care between July 2009 and June 2010 were identified from source files. PRINCIPAL FINDINGS: Neither treatment by itself has a statistically significant effect on hospital readmission. In combination, however, they reduce the probability of readmission by roughly 8 percentage points (p < .001; confidence interval = -12.3, -4.1). Results are robust to changes in implementation of the nonlinear IV estimator, sample, outcome measure, and length of follow-up. CONCLUSIONS: Our results call for closer coordination between home health and medical providers in the clinical management of HF patients immediately after hospital discharge.

RESUMEN

AIM: Assess the comparative effectiveness of two blood pressure (BP) control interventions for black patients with uncontrolled hypertension. PATIENTS & METHODS: A total of 845 patients were enrolled in a three-arm cluster randomized trial. On admission of an eligible patient, field nurses were randomized to usual care, a basic or augmented intervention. RESULTS: Across study arms there were no significant 12 months differences in BP control rates (primary outcome) (25% usual care, 26% basic intervention, 22% augmented intervention); systolic BP (143.8 millimeters of mercury [mmHg], 146.9 mmHG, 143.9 mmHG, respectively); medication intensification (47, 43, 54%, respectively); or self-management score (18.7, 18.7, 17.9, respectively). Adjusted systolic BP dropped more than 10 mmHg from baseline to 12 months (155.5-145.4 mmHg) among all study participants. CONCLUSION: Neither the augmented nor basic intervention was more effective than usual care in improving BP control, systolic BP, medication intensification or patient self-management. Usual home care yielded substantial improvements, creating a high comparative effectiveness threshold. CLINICAL TRIAL REGISTRATION: NCT00139490.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate UK trainee experience in endoscopy for acute upper gastrointestinal bleeding (AUGIB). METHODS: Data was prospectively collected from all patients presenting to South Yorkshire Hospitals with AUGIB from September 2011 to December 2011 and compared with data from 1996. Concurrently, all gastroenterology trainees registered with the British Society of Gastroenterology were invited to respond to a web-based questionnaire regarding their experience in AUGIB management. RESULTS: 77% (589/766) of the patient cohort underwent endoscopy for AUGIB; 15% (90/589) were performed by trainees. 7.2% (9/125) of the out of hours endoscopy case load was performed by trainees; all were low-risk or medium-risk cases (pre-endoscopy Rockall score ≤4). During the study period, dual therapy was delivered by a trainee on only four occasions. Comparison with the 1996 cohort demonstrated a marked reduction in the number of trainee performed endoscopies (76% vs 15%; p<0.001). Questionnaires were returned by 51% (245/478) of British Society of Gastroenterology trainees. 81% (198/245) thought that <10% of the gastroscopies they had performed involved therapeutic intervention. 23% (57/245) felt they would not be competent in AUGIB endoscopy by completion of specialty training. CONCLUSIONS: This study demonstrates the decline over time in trainee experience in AUGIB endoscopy. It also highlights a lack of trainee exposure to more challenging cases, out of hours endoscopy and therapeutic procedures. Furthermore, trainees are concerned that a level of competency may not be attained during specialty training. We advocate reviewing UK endoscopic training provision for AUGIB to ensure that experienced endoscopists are produced to meet future service needs.
