Support electron inductive effect of Pd-Mn/Ni foam catalyst for robust electrocatalytic hydrodechlorination.

Structural regulation of Pd-based electrocatalytic hydrodechlorination (EHDC) catalyst for constructing high-efficient cathode materials with low noble metal content and high atom utilization is crucial but still challenging. Herein, a support electron inductive effect of Pd-Mn/Ni foam catalyst was proposed via in-situ Mn doping to optimize the electronic structure of the Ni foam (NF), which can inductive regulation of Pd for improving the EHDC performance. The mass activity and current efficiency of Pd-Mn/NF catalyst are 2.91 and 1.34 times superior to that of Pd/NF with 2,4-dichlorophenol as model compound, respectively. The Mn-doped interlayer optimized the electronic structure of Pd by bringing the d-state closer to the Fermi level than Pd on the NF surface, which optimizied the binding of EHDC intermediates. Additionally, the Mn-doped interlayer acted as a promoter for generating H* and accelerating the EHDC reaction. This work presents a simple and effective regulation strategy for constructing high-efficient cathode catalyst for the EHDC of chlorinated organic compounds.

Tailored design of novel Co0-Coδ+ dual phase nanoparticles for selective CO2 hydrogenation to ethanol.

Catalytic hydrogenation of CO2 to ethanol is a promising solution to address the greenhouse gas (GHG) emissions, but many current catalysts face efficiency and cost challenges. Cobalt based catalysts are frequently examined due to their abundance, cost-efficiency, and effectiveness in the reaction, where managing the Co0 to Coδ+ ratio is essential. In this study, we adjusted support nature (Al2O3, MgO-MgAl2O4, and MgO) and reduction conditions to optimize this balance of Co0 to Coδ+ sites on the catalyst surface, enhancing ethanol production. The selectivity of ethanol reached 17.9% in a continuous flow fixed bed micro-reactor over 20 mol% Co@MgO-MgAl2O4 (CoMgAl) catalyst at 270 °C and 3.0 MPa, when reduced at 400 °C for 8 h. Characterisation results coupled with activity analysis confirmed that mild reduction condition (400 °C, 10% H2 balance N2, 8 h) with intermediate metal support interaction favoured the generation of partially reduced Co sites (Coδ+ and Co0 sites in single atom) over MgO-MgAl2O4 surface, which promoted ethanol synthesis by coupling of dissociative (CHx*)/non-dissociative (CHxO*) intermediates, as confirmed by density functional theory analysis. Additionally, the CoMgAl, affordably prepared through the coprecipitation method, offers a potential alternative for CO2 hydrogenation to yield valuable chemicals.

Un análisis integrado entre la calidad de vida y las necesidades de apoyo de personas adultas con discapacidad intelectual en Chile / An integrated analysis between the quality of life and the support needs of adults with intellectual disabilities in Chile

El paradigma de apoyos y el de calidad de vida se han transformado en guías fundamentales para los avances en el ámbito de la discapacidad intelectual (DI). Con base en una muestra de 93 personas adultas con DI, se analiza, desde un enfoque cuantitativo no experimental, la relación entre la calidad de vida y las necesidades de apoyo, aplicando la escala INICO-FEAPS y la escala de Intensidad de Apoyos (SIS) para cada constructo. Los principales resultados evidencian que existe una relación fuerte e indirecta entre calidad de vida y necesidades de apoyos, y también la relevancia de analizar dichos resultados desde variables como grado de discapacidad, sexo o nivel socioeconómico. La discusión permite inferir la necesidad de discutir nuevas estrategias en torno a categorías como el grado de discapacidad, la autodeterminación e inclusión social, como elementos facilitadores de la calidad de vida y apoyos desde un enfoque integral que contribuya al desarrollo de estrategias de programas sociales para la población con DI.

Perceived access to social support during and after TB treatment in Mbeya and Songwe regions, Tanzania: perspectives from TB patients and survivors set against health care providers.

Introduction: Pulmonary tuberculosis (PTB) remains a life-threatening disease in Tanzania, with negative physical, financial, economic and psychosocial consequences to individuals and the society. It mainly lowers the quality of life of patients, survivors and their families, especially those in the poorest and socially deprived categories. Objectives: To report and discuss a qualitative study that assessed the nature of social support desired and received by PTB patients and survivors. Participants were given a chance to share their experiences and their perceptions on whether the social support they desired had an impact on their treatment-seeking behaviour and treatment adherence. Methods: Face-to-face interviews were conducted with the three aforementioned groups, purposively selected at a TB clinic between October 2020 and March 2021. The questions covered topics related to the types of social support desired and the sources of support during and after treatment, if any. Interviews were concluded until no new information was obtained. Data analysis was facilitated using NVivo 12 software. Results: Participants pointed out a need for psychosocial, financial, and material support during and after treatment. However, they sometimes miss support from family/household members or the rest of the community. Because of this experience, they lived with difficulties, facing hardships when required to pay out of pocket for transport during the care-seeking. Survivors testified experience of a denial of support by even their close relatives who regarded them as no longer needing it after recovering. Patients and survivors also reported experience of social isolation as they were believed able to transmit PTB infections. Limited psychological support at the contacted TB clinics was another experience reported. TB clinic staff's experiences confirmed almost all the experiences shared by their clients. With limited support, resilience and self-care were identified as key mechanisms for coping. Conclusion: Complete recovery from PTB is possible, but reverting to a normal life is difficult without social support. Policies and programs need to increase opportunities for social support for TB patients and survivors. Doing so is likely to improve TB-related treatment, care-seeking practices, and adherence.

Research and exploration of quality control indicators for nutritional therapy in critically ill patients-a multicenter before-and-after controlled study.

Objective: To evaluate and explore the feasibility of using quality control indicators for nutritional therapy in critically ill patients as quality evaluation criteria. Methods: This study focused on intensive care unit (ICU) critically ill patients and conducted a cross-sectional investigation of nutritional therapy quality control indicators (the proportion of patients with application of enteral nutrition pump, nutritional risk assessment rate, the proportion of patients start enteral nutrition within 48 hours, and caloric and protein target achievement rate on 7th day) in 13 hospitals in Jilin Province. After training according to the critical patients nutrition related guidelines and the latest literatures, a second cross-sectional investigation was conducted. Then, analyze the improvement of quality control indicators of the nutritional therapy before and after the training, thus evaluating the feasibility of using these quality control indicators as nutritional therapy quality evaluation criteria in critical patients. Results: (1) A total of 631 patients were included before and after training, with a data acquisition rate of 97.3% for enteral nutrition pumps usage and complete data collection for the remaining nutritional risk assessment rate, start enteral nutrition proportion of patients within 48 h, and caloric and protein target achievement rate on 7th day. (2) The nutritional risk assessment rate before and after training was 88.2% vs. 94.8%, with a P-value of 0.003. The proportion of patients start enteral nutrition within 48 h before and after training was 65.1% vs. 75.4%, with a P-value of 0.039; and protein target achievement rate on 7th day before and after training was 64.6% vs. 79.6%, with a p-value of 0.015. These five indicators as quality evaluation criteria are relevant to the current developments in nutritional therapy and consistent with the national conditions of China. The proportion of patients with application of enteral nutrition pump before and after training was 70.1% vs. 79.4%, with a p-value of 0.065, and the caloric target achievement rate on 7th day before and after training was 73.4% vs. 83.9%, with a p-value of 0.062, and there was no statistical difference between the two groups. Conclusion: The five quality control indicators for nutritional therapy in critically ill patients are clinically feasible and can be used as quality evaluation criteria for nutritional therapy in critically ill patients.

Effects of psychological support intervention on patients with nasopharyngeal carcinoma undergoing radiotherapy.

Objective: To find out the effects of psychological support intervention on patients with nasopharyngeal carcinoma undergoing radiotherapy. Methods: This was a retrospective study. Sixty six patients with nasopharyngeal carcinoma who received radiotherapy in the Affiliated Hospital of Hebei University from March 2021 to March 2022 were included and randomly divided into the observation group and the control group, with 33 cases in each group. Patients in the control group were given conventional care measures, while those in the observation group were given psychological support intervention on top of conventional care measures. The nursing effects between the two groups were compared. Results: After the intervention, the psychological resilience score of the observation group was significantly higher than that of the control group, with a statistically significant difference (P<0.05). The psychological resilience scores after the intervention were significantly higher in the observation group than before the intervention, and those in the control group were higher than before the intervention, with a statistically significant difference(P<0.05). The overall health score of quality of life in the observation group was significantly higher than that in the control group after the intervention, with a statistically significant difference(P<0.05). Moreover, the skin reaction in the observation group after radiotherapy was significantly better than that of the control group (P<0.01). Conclusion: Psychological support intervention is an effective means to treat patients with nasopharyngeal carcinoma, which results in various benefits such as improving patients' mental resilience and quality of life and reducing the incidence of adverse reactions after radiotherapy.

Gerontology in Public Health: A Scoping Review of Current Perspectives and Interventions.

The intersection of gerontology and public health is increasingly vital due to the global aging population and its implications for health systems. This scoping review aims to map existing literature on gerontology within public health, identify current perspectives, and evaluate interventions tailored to the needs of older adults. A systematic search was performed using predefined keywords across multiple databases, including PubMed, Google Scholar, Scopus, and Web of Science. The review included 42 studies that employed various designs, all focusing on public health interventions targeting the aging population.  Key findings indicate a pressing need to integrate gerontological principles into public health practice, recognizing the heterogeneous nature of older adults and the significance of social determinants of health. Interventions ranged from preventive health measures and chronic disease management programs to health promotion activities and caregiver support, including the application of technology to improve health outcomes. However, there was a notable lack of research on diverse populations and mental health interventions. The review also uncovered critical gaps in the literature, such as economic barriers to care access and the necessity for comprehensive policies addressing the aging population's diverse needs. In conclusion, this review emphasizes the importance of a multidimensional approach to effectively addressing older adults' health needs. While several effective interventions exist, there is an urgent need to tackle identified gaps, particularly concerning diverse populations and mental health, to enhance overall health strategies for the aging demographic.

The Future of Artificial Intelligence in Surgery.

Until recently, innovations in surgery were largely represented by extensions or augmentations of the surgeon's perception. This includes advancements such as the operating microscope, tumor fluorescence, intraoperative ultrasound, and minimally invasive surgical instrumentation. However, introducing artificial intelligence (AI) into the surgical disciplines represents a transformational event. Not only does AI contribute substantively to enhancing a surgeon's perception with such methodologies as three-dimensional anatomic overlays with augmented reality, AI-improved visualization for tumor resection, and AI-formatted endoscopic and robotic surgery guidance. What truly makes AI so different is that it also provides ways to augment the surgeon's cognition. By analyzing enormous databases, AI can offer new insights that can transform the operative environment in several ways. It can enable preoperative risk assessment and allow a better selection of candidates for procedures such as organ transplantation. AI can also increase the efficiency and throughput of operating rooms and staff and coordinate the utilization of critical resources such as intensive care unit beds and ventilators. Furthermore, AI is revolutionizing intraoperative guidance, improving the detection of cancers, permitting endovascular navigation, and ensuring the reduction in collateral damage to adjacent tissues during surgery (e.g., identification of parathyroid glands during thyroidectomy). AI is also transforming how we evaluate and assess surgical proficiency and trainees in postgraduate programs. It offers the potential for multiple, serial evaluations, using various scoring systems while remaining free from the biases that can plague human supervisors. The future of AI-driven surgery holds promising trends, including the globalization of surgical education, the miniaturization of instrumentation, and the increasing success of autonomous surgical robots. These advancements raise the prospect of deploying fully autonomous surgical robots in the near future into challenging environments such as the battlefield, disaster areas, and even extraplanetary exploration. In light of these transformative developments, it is clear that the future of surgery will belong to those who can most readily embrace and harness the power of AI.

Roles of Chaplains and Clergy in Spiritual Care for African Americans in Hospice: A Pilot Study.

CONTEXT: Spiritual care is recognition of patient and caregiver spiritual/religious needs and attention to those needs. Caregivers of African American hospice patients are more likely to report worse emotional/religious support. Yet, spiritual care delivery and roles of community clergy and chaplains for African American hospice patients are not well understood. OBJECTIVES: Examine who provides spiritual care to African American hospice patients and caregivers. METHODS: Partnering with large, urban/suburban community hospice, we interviewed caregivers of deceased African American hospice patients (n = 12), their clergy (n = 3) and chaplains (n = 5). Using a phenomenological qualitative study design, we coded transcripts and deceased patient chart data and conducted thematic analysis to identify themes. RESULTS: Community clergy and chaplains tend to not interact and provide different aspects of emotional, religious and spiritual support to hospice patients and families. Clergy and chaplains agreed that rapport and openness of the patient were main factors in meeting spiritual care needs. Clergy provided interaction with a trusted person and connection to church, congregational support, religious beliefs/theology, and practices. Chaplains focused on present needs and issues of death and dying. CONCLUSION: Clergy and chaplains have distinct, complementary roles in providing spiritual care to African American hospice patients and families. Both are needed to provide desired spiritual care for African American hospice patients and their caregivers. Robust spiritual care programs need to ensure chaplains have sufficient time to spend with patients and families and incorporate collaboration, handoffs and integrated processes for clergy and chaplains. Research is needed on effectively including clergy in hospice spiritual care delivery.

Implementation and Qualitative Analysis of Peer Support for New Pediatric Gastrostomy Tube Families.

INTRODUCTION: Gastrostomy tube (G-tube) insertion in children has frequent complications, including dislodgment and return to the system, which are associated with emotional burden for caregivers. To address these issues, we developed a peer support program for caregivers of children with new G-tubes and aimed to explore program feasibility and acceptability. METHODS: The G-tube Buddy Program is a peer support program that pairs an experienced G-tube caregiver with new G-tube caregivers. Between April 2022 and December 2022, seven mentors and 21 mentees participated in the program. Five mentors and ten mentees participated in semi-structured focus groups and interviews. Transcripts were analyzed using both inductive and deductive qualitative methods. RESULTS: We identified five prominent domains: peer support relationship dynamics; mentor and mentee-specific factors; determinants of program success; mentor and mentee perception of the program; and suggestions for program improvement. These domains encompassed main themes: support consisted primarily of assistance with daily life and social and emotional support; texting was usually the preferred communication method; mentee satisfaction is rooted in humanness, teaching, and generation of hope; mentors participated due to positive feelings regarding helping new caregivers with financial motivation being less important; and, participants perceived the program as a valuable source of support for new caregivers that complements and expands the reach of care they receive from clinical providers. CONCLUSIONS: A peer support model for families with new G-tubes appears feasible and acceptable from participant perspectives. Responses validate the program's potential to add value to the postoperative care of children with G-tubes and will guide program optimization.

A pre-post evaluation of a digital intervention to improve psychosocial outcomes of caregivers of people living with cancer in Vietnam.

OBJECTIVES: To evaluate a co-designed intervention using digital resources "Vietnam Cancer Caring Coping" (V-CCC) on the health literacy, depression, and quality of life of caregivers supporting a cancer patient in oncology hospitals in Vietnam. METHODS: A pre-post quantitative evaluation with adult cancer caregivers across regional Oncology hospitals in Vietnam (Ho Chi Minh City, Da Nang, Can Tho, and Hue). Participants completed baseline and follow-up measures of health literacy (HLS-SF12) depression (PHQ-9) and Health-related Quality of Life (5Q-5D-5L). Participants accessed and reviewed V-CCC for a 2-week period. RESULTS: Two hundred and thirty-four caregivers completed pre and post-tests. Most participants were female (n = 143, 61%), married (n = 165, 70%), aged 18-44 (n = 155, 66%), lived rurally (n = 157, 67%). All health literacy scores of participants in post-intervention were significantly higher than that in pre-intervention across all domain's healthcare, disease prevention, and health promotion as well as the total score (p < 0.001). A significant reduction in the proportion of caregivers reporting PHQ-9 moderately severe/severe depression post-intervention was demonstrated (10.2 vs. 6.1%, respectively (p ≤ 0.001). No significant differences were observed pre and post-intervention across four 5Q-5D-5L health dimensions: mobility, self-care, usual activities, and pain/discomfort. Regarding anxiety/depression as measured by 5Q-5D-5L the proportion of participants who reported having moderate, severe, and extreme problems in pre- and post-intervention was statistically significant (32 vs. 24%), respectively (p = 0.0028). CONCLUSION: Co-designed digital resources can reduce health literacy inequities and improve psychological outcomes for cancer caregivers.

Influential factors of adherence to inhalation drug therapy in patients with stable chronic obstructive pulmonary disease.

OBJECTIVE: This study aimed to investigate the influential factors of adherence to inhalation drug therapy (IDT) in patients with stable chronic obstructive pulmonary disease (COPD). METHODS: A total of 243 patients with stable COPD who visited the chronic disease clinic of the respiratory department of our hospital between April 2022 and October 2022 were selected as participants using the convenience sampling method. Relevant information about all participants was collected by questionnaire for investigation, including basic information, clinical characteristics, inhaled drug names, situational awareness, dose and frequency. RESULTS: Univariate analysis revealed positive correlations between the following factors: (1) the total score of drug adherence and the total scores of the COPD knowledge questionnaire (COPD-Q), social support, subjective support, objective support and support utilisation, (2) the total score of dosage adherence and the total scores of COPD-Q, objective support and support utilisation and (3) the total score of technical standardisation and the total scores of social support, subjective support and objective support (p < 0.05). Multifactorial analysis showed that COPD health literacy, number of acute exacerbations in the past year and social support factors collectively accounted for 37.4% of the variable of patient adherence to IDT, as did COPD health literacy, modified Medical Research Council (mMRC) grading, duration of COPD, utilisation of support and marital status collectively account for 47.4% of the variable of patient dosage adherence. The goodness-of-fit of age, mMRC grading, social support, mode of residence, number of acute exacerbations in the past year and literacy to the patients' inhalation technical standardisation in the model was 47.4%. CONCLUSION: Dose adherence was predominantly influenced by COPD health literacy, mMRC grading, duration of COPD, utilisation of support and marital status. Inhalation technical standardisation was substantially limited by age, mMRC grading, social support, mode of residence, number of acute exacerbations in the past year and literacy.

The Insidiousness of Institutional Betrayal: An Ecological Systematic Review of Campus Sexual Violence Response Literature.

Recently, post-secondary institutions have been under increased public and academic scrutiny regarding their ability to prevent and respond to instances of campus sexual violence. Emerging research has explored institutional betrayal (IB), which is a theoretical framework that states that actions and inactions on the part of the institution can cause further harm to survivors of violence. The goals of this review were, using an ecological systems lens, to identify what specific behaviors, policies, responses, and other factors constitute IB or institutional support (IS) as defined by the existing literature. A search of 16 databases across 8 disciplines led to the identification of 100 articles that mentioned either IB or IS verbatim. Factors that can be categorized as IB and IS were identified across nine levels: (1) the individual level, (2) the interpersonal level, (3) within institutional spaces, (4) within institutional procedures, (5) within institutional policies, (6) at the institutional structural level, (7) at the institutional culture level, (8) at a government and public policy level, and (9) within greater societal cultural values and established social norms. IB itself manifests across all levels of the institution and is, in fact, quite insidious-it is largely invisible and deeply rooted in systemic oppression, woven into the structure of institutions of higher education. IB remains a looming, almost inevitable outcome of the structural violence that occurs in post-secondary settings. Yet, IS and the related concept of institutional courage are emerging fields of study that pose important implications for institutional change.

Ambivalent Speculations: Learning to Live with Barrett's Esophagus in the UK Using Facebook Support Groups.

Drawing on fieldwork in Facebook support groups, in this article I explore how people, now patients, learnt to live with Barrett's esophagus, a risk state or "precancer" for a type of esophageal cancer. This diagnosis brought the possibility of both facing and averting cancerous futures into the present. Far from passive recipients, members worked to foreground speculations of "wanted futures" in which prompt surveillance successfully prevented cancer deaths, transforming cancer risk into an opportunity for hope. Speculation here was an ambivalent and active process, involving not only the "observation of potentiality," but the opening up and foreclosing of both desirable and undesirable potentialities.

Operational Mechanisms of Peer Support Groups and Support for Caregivers of People Living with Serious Mental Illness.

The challenges faced by caregivers of people living with serious mental illness in Canada are well documented in the literature including emotional distress, financial strain, social isolation, and concerns about their physical health following the impact of caregiving. Peer support programs (including peer support groups) emerged as a promising method to attempt to address these challenges. While there is evidence on the positive impacts of peer support groups in providing support for caregivers, the mechanisms by which peer support groups operate and influence support for caregivers of people living with serious mental illness are less understood. This qualitative study took on a co-designed participatory research approach. Fifteen adult caregivers of people living with serious mental illness across Canada were engaged through key informant interviews that lasted for 45 - 60 min each. A thematic analysis was carried out to help understand the operational mechanisms of peer support groups in influencing support for caregivers. The key informant interviews allowed for the identification and description of the following operational mechanisms that influenced the support caregivers received from peer support groups: (1) Group dynamics; (2) Messaging/content; (3) Equity and inclusion, (4) Group philosophy; and (5) Privacy concerns. Findings from this study showed that caregivers identified a number of operational mechanisms of peer support groups that explained how they felt supported when they participated in peer support groups. Among other operational mechanisms, group dynamics in terms of the gathering of caregivers of different age brackets and varying caregiving experience negatively influenced the peer support experience of caregivers. This pointed to the need for group dynamics that consider close age ranges and similar caregiving experience during group meetings to enhance support for caregivers. Caregivers also identified a gap in equity and inclusion in peer support groups that could have otherwise enriched their experience and enhanced the support they looked to receive from the group. Practical examples to enhance equity and inclusion include promoting active listening, using inclusive language, encouraging diverse representation and asking for feedback from peer support group members. While peer support groups in Canada exist independently of one another, it may help to consolidate evidence-based recommendations in the operational mechanisms of these groups, for the benefit of caregivers who turn to these groups for support, having been left on their own by an otherwise fractured mental health system.

Comparison of characteristic competencies of public health nurses working at a community general support center and health and welfare in public administration in Japan.

Objectives: To compare the characteristic competencies of public health nurses working for the older adult's health and welfare in public administration ("PA") with those at community general support centers ("CGSC") in Japan. Methods: We conducted a questionnaire survey by mail for PA and CGSC public health nurses. A competency list that was developed to compare three groups (PA, CGSC experts with ≥5 years of experience, and CGSC newcomers with ≤2 years of experience) was used. The following characteristics were examined: (1) competencies acquired early after arriving at the CGSC, (2) competencies acquired through a certain amount of CGSC experience, (3) common competencies, (4) competencies that even experts lacked, and (5) competencies that the newcomers lacked. Results: We examined the responses of 171 PA nurses, 185 CGSC expert public health nurses, and 165 CGSC newcomer public health nurses. The results of comparison of the three groups showed that (1) had no applicable items; (2) had nine items for individual support associated with preventive care management; (3) had 14 items including teamwork among three professionals (social workers, senior care manager, public health nurse)/other professionals and self-improvement; (4) had three items for community development, (5) had two items for individual support and 16 items for community development. Conclusion: Initiatives for preventive care and coordination of care teams should be supported and suggested as characteristic competencies for CGSC public health nurses.

Social support and frailty progression in community-dwelling older adults.

Objectives: Despite the growing evidence regarding the influence of social factors on frailty in older adults, the effect of social support remains unclear. This study aims to assess the association between social support and frailty progression (transition and incidence) in a sample of community-dwelling older adults. Methods: Using a cohort study design, 1,059 older adults from the Berlin Initiative Study were followed up for 2.1 years. Multinomial and logistic regression analyses were performed to assess the association of social support using Oslo Social Support Scale-3 with frailty transition and incidence, respectively. Gender differences were explored using stratified analyses. Results: At baseline, frailty prevalence in the study population [mean (SD) age 84.3 (5.6) years; 55.8% women] reached 33.1% with 47.0, 29.4 and 23.6% of the participants reporting moderate, strong and poor social support, respectively. Over the follow-up period, social support was not significantly associated with the frailty transition categories in the adjusted model. Conversely, the adjusted logistic regression analysis showed that participants with poor social support had twice the odds of becoming frail compared to those with strong social support (OR 2.07; 95% CI 1.08-3.95). Gender-stratified analyses showed comparable estimates to the main analysis but were statistically non-significant. Discussion: Our study results underpin the role of social factors in frailty incidence and highlight social support as a potential target for frailty-preventing interventions in older adults. Therefore, it is important to adopt a biopsychosocial model rather than a purely biomedical model to understand and holistically improve the health of community-dwelling older adults.
