Evaluating the association between receipt of a winter fuel cash transfer and older people's care needs, quality of life, and housing quality: Evidence from England.

BACKGROUND: Exposure to cold temperatures is known to be associated with deterioration of physical and mental health as well as poorer well-being in many countries. The Winter Fuel Payment, an unconditional direct cash transfer of value between £250-£300, was designed to help older people in England cover heating costs during the winter months, to counteract the particular vulnerability of older people to the effects of cold weather. AIMS: We evaluated the impact of the Winter Fuel Payment scheme on subsequent prevalence of care needs such as being unable to eat or shower independently, quality of life and the likelihood of having cold-related housing conditions. We also explored the potential effects of the Winter Fuel Payment across different sub-samples (poorer/richer individuals, those living in newer/older properties, and in the North/South of England) to explore whether its benefits (if any) are spread equally across the eligible population. DATA AND METHODS: We used a regression discontinuity design approach with age as running variable to analyse seven waves of a nationally representative sample, the English Longitudinal Study of Ageing, covering the period 2002/2003 to 2016/2017, and consisting of 24,651 observations. RESULTS: The Winter Fuel Payment had no overall effect on the outcomes of interest (care needs, quality of life, and cold-related housing problems). However, the Payment increased quality of life for poorer individuals, for those living in Northern regions of England, and for those living in newer dwellings. The likelihood of living in a property with at least one cold-related housing problem also decreased for those living in newer properties. CONCLUSIONS: Findings from this research provide important insights into the effectiveness of a winter cash transfer among the older population in England, and they are potentially relevant for other nations looking for strategies to deal with cold seasons and poorly insulated homes. In particular, this evaluation contributes to the 'universality versus targeting' policy debate and has implications for the development of energy-efficient policies.

An analysis of potentially avoidable neurosurgical transfers to a tertiary-care level I trauma center.

OBJECTIVE: Previous studies of neurosurgical transfers indicate that substantial numbers of patients may not need to be transferred, suggesting an opportunity to provide more patient-centered care by treating patients in their communities, while probably saving thousands of dollars in transport and duplicative workup. This study of neurosurgical transfers, the largest to date, aimed to better characterize how often transfers were potentially avoidable and which patient factors might affect whether transfer is needed. METHODS: This was a retrospective cohort study of neurosurgical transfers to an urban, tertiary-care, level I trauma center between October 1, 2017, and October 1, 2022. Prior to data analysis, the authors devised criteria to differentiate necessary neurosurgical transfers from potentially avoidable ones. A transfer was considered necessary if 1) the patient went to the operating room within 12 hours of arrival at the emergency department (ED); 2) a neurological MRI study was conducted in the ED; 3) the patient was admitted to the ICU from the ED; or 4) the patient was admitted to either neurology or a surgical service (including neurosurgery). Transfers not meeting any of the above criteria were deemed potentially avoidable. Patient and clinical characteristics, including diagnostic groupings from Clinical Classification Software categories, were collected retrospectively via electronic health record data abstraction and stratified by whether the transfer was necessary or potentially avoidable. Statistical differences were assessed with a chi-square test. RESULTS: A total of 5113 neurosurgical transfers were included in the study, of which 1701 (33.3%) were classified as potentially avoidable. Four percent of all transferred patients went to the operating room within 12 hours of reaching the receiving ED, 23.4% were admitted to the ICU from the ED, 26.6% had a neurological MRI study performed in the ED, and 54.4% were admitted to a surgical service or to neurology. Potentially avoidable transfers had a higher proportion of traumatic brain injury, headache, and syncope (p < 0.0001), as well as of spondylopathies/spondyloarthropathies (p = 0.0402), whereas patients needing transfer had a higher proportion of acute hemorrhagic cerebrovascular disease and cerebral infarction (p < 0.0001). CONCLUSIONS: This study demonstrates that a large number of neurosurgical transfers can probably be treated in their home hospitals and highlights that the vast majority of patients transferred for neurosurgical conditions do not receive emergency neurosurgery. Further research is needed to better guide transferring and receiving facilities in reducing the burden of excessive transfers.

The density of the inner cell mass is a new indicator of the quality of a human blastocyst: a valid supplement to the Gardner scoring system.

STUDY QUESTION: Can the density of the inner cell mass (ICM) be a new indicator of the quality of the human blastocyst? SUMMARY ANSWER: The densification index (DI) developed in this study can quantify ICM density and provide positive guidance for ploidy, pregnancy, and live birth. WHAT IS KNOWN ALREADY: In evaluating the quality of ICM, reproductive care clinics still use size indicators without further evaluation. The main disadvantage of this current method is that the evaluation of blastocyst ICM is relatively rough and cannot meet the needs of clinical embryologists, especially when multiple blastocysts have the same ICM score, which makes them difficult to evaluate further. STUDY DESIGN, SIZE, DURATION: This observational study included data from 2272 blastocysts in 1991 frozen-thawed embryo transfer (FET) cycles between January 2018 to November 2021 and 1105 blastocysts in 430 preimplantation genetic testing cycles between January 2019 and February 2023. PARTICIPANTS/MATERIALS, SETTING, METHODS: FET, ICSI, blastocyst culture, trophectoderm biopsy, time-lapse (TL) monitoring, and next-generation sequencing were performed. After preliminary sample size selection, the 11 focal plane images captured by the TL system were normalized and the spatial frequency was used to construct the DI of the ICM. MAIN RESULTS AND THE ROLE OF CHANCE: This study successfully constructed a quantitative indicator DI that can reflect the degree of ICM density in terms of fusion and texture features. The higher the DI value, the better the density of the blastocyst ICM, and the higher the chances that the blastocyst was euploid (P < 0.001) and that pregnancy (P < 0.001) and live birth (P = 0.005) were reached. In blastocysts with ICM graded B and blastocysts graded 4BB, DI was also positively associated with ploidy, pregnancy, and live birth (P < 0.05). ROC analysis showed that combining the Gardner scoring system with DI can more effectively predict pregnancy and live births, when compared to using the Gardner scoring system alone. LIMITATIONS, REASONS FOR CAUTION: Accurate calculation of the DI value places high demands on image quality, requiring manual selection of the clearest focal plane and exposure control. Images with the ICM not completely within the field of view cannot be used. The association between the density of ICM and chromosomal mosaicism was not evaluated. The associations between the density of ICM and different assisted reproductive technologies and different culture conditions in embryo laboratories were also not evaluated. Prospective studies are needed to further investigate the impact of ICM density on clinical outcomes. WIDER IMPLICATIONS OF THE FINDINGS: ICM density assessment is a new direction in blastocyst assessment. This study explores new ways of assessing blastocyst ICM density and develops quantitative indicators and a corresponding qualitative evaluation scheme for ICM density. The DI of the blastocyst ICM developed in this study is easy to calculate and requires only TL equipment and image processing, providing positive guidance for clinical outcomes. The qualitative evaluation scheme of ICM density can assist embryologists without TL equipment to manually evaluate ICM density. ICM density is a simple indicator that can be used in practice and is a good complement to the blastocyst scoring systems currently used in most centers.

Cash transfers and mental health in Egypt.

The relationship between poverty and mental health is complex. Conditional cash transfers are seen as an important policy tool in reducing poverty and fostering social protection. Evidence on the impact of cash transfers on mental health is mixed. In this study, we assess the causal impact of Egypt's conditional cash transfer (CCT) programme Takaful on the main recipients' mental health. Using a regression discontinuity design, we find that receiving the Takaful CCT does not have a significant impact on the anxiety levels of mothers in our sample. In addition, we do not find supporting evidence that the programme has heterogeneous impacts on anxiety levels. We discuss possible explanations behind these null results.

Why Study Guaranteed Income in Oncology? Lessons Learned From Launching the Guaranteed Income and Financial Treatment Trial.

By targeting income and financial stress as key social determinants of health, unconditional cash transfers (UCTs) may improve cancer health outcomes and reduce cancer health disparities. Described in policy circles as guaranteed or basic income, UCTs have been shown to improve a range of health outcomes in low-income populations but have not yet been examined as a targeted intervention for people with cancer. This article describes some of the lessons learned from launching the Guaranteed Income and Financial Treatment trial, a two-arm randomized controlled trial of UCTs in oncology, along with a rationale for studying UCTs in people with cancer who have low incomes, and presents an introductory primer on UCT research for oncology clinicians and researchers and future directions for research.

Oil-soluble contrast medium bathing attenuated endometrial inflammation and improved endometrial receptivity in women with recurrent implantation failure: a descriptive study.

BACKGROUND: The oil-soluble contrast medium used in hysterosalpingography has been shown to have a fertility-enhancing effect, but the underlying mechanism is unclear, especially regarding the role of window of implantation (WOI). This study aimed to assess the endometrial immunological impact of the WOI before and after bathing with the oil-soluble contrast medium in women with recurrent implantation failure (RIF). METHODS: This descriptive study involved two medical centers between December 18, 2019, and December 30, 2020. We included infertile women who underwent three or more transfer cycles, cumulative transplantation of at least four high-quality cleavage-stage embryos or three high-quality blastocysts without clinical pregnancy, and high-quality frozen embryos that were still available for implantation. Patients received 5 ml of ethiodized poppyseed oil bathing, endometrial biopsy around bathing, and frozen-thawed embryo transfer (FET) within four menstrual cycles after bathing. Patients were excluded if failure to complete anyone. Data on the baseline characteristics and clinical data of the FET cycles were collected, and endometrial biopsy specimens were collected in the luteal phase before and after bathing and subjected to immunohistochemistry. The number of CD56 and CD138 positive cells and H-score of expression of ανß-3 and HOXA10 in endometrium were collected. RESULTS: Thirty-four patients were initially enrolled in the study; ultimately, twelve patients with a median age of 32.5 years (range 27-40 years) completed the research. The median number of embryo transfer cycles was three (range 3-8). A total of 4 of 12 women (33.33%) were diagnosed with chronic endometritis before oil-soluble contrast bathing. After bathing, the median numbers of CD138-positive cells in endometrium decreased from 0.75 (range 0-13.5) to 0.65 (range 0-6), P = 0.035; additionally, the H-score of expression of ανß-3 in endometrium increased from 148.50 ± 31.63 to 175.58 ± 31.83, P < 0.001. The thickness of the endometrium also significantly increased (8.90 ± 1.45 mm vs.10.11 ± 1.98 mm, P = 0.005). However, no consistent changes were found in the expression of CD56 and HOXA10 in the endometrium. Five patients experienced biochemical pregnancies (41.67%), four had clinical pregnancies (33.33%), and three achieved live births following oil-soluble contrast bathing (25%). CONCLUSIONS: These results suggest that oil-soluble contrast medium bathing decreased CD138-positive cells and upregulated expression of ανß-3 during WOI in patients with RIF. This histological impact of endometrium may result in enhanced fertility during FET cycles. Investigating the ability of intrauterine bathing with lower-dosage oil-soluble contrast to improve pregnancy in the RIF population is warranted.

Social protection as a strategy for HIV prevention, education promotion and child marriage reduction among adolescents: a cross-sectional population-based study in Lesotho.

BACKGROUND: Lesotho's government has shown consistent efforts to implement social protection programmes. However, while recent evidence established a positive causal relationship between some of these programmes and food security there is little evidence on the extent to which these initiatives are associated with better educational and sexual and reproductive health outcomes among vulnerable adolescents in Lesotho. METHODS AND FINDINGS: The study uses cross-sectional, nationally representative data from the 2018 Lesotho Violence Against Children and Youth Survey. Our research examined the association between social protection receipt and educational and sexual and reproductive health outcomes among adolescents and young people (13-24 years) living in poverty. We employed multivariate logistic regression controlling for age, orphanhood, HIV status and sex. Social protection receipt was defined as household receipt of financial support from a governmental, non-governmental, or community-based program that provides income. Additionally, we fitted a marginal effects model by sex. Among the 3,506 adolescent females and males living in the two lowest poverty quintiles, receipt of social protection was associated with improvements in multiple adolescent outcomes: higher odds of consistent condom use (aOR 1.64, 95% CI 1.17-2.29), educational attainment (aOR 1.79, 95% CI 1.36-2.36), and school enrolment (aOR 2.19, 95% CI 1.44-3.34). Stratified analyses by sex showed that social protection receipt was also associated with reduced likelihood of child marriage among females (aOR 0.59, 95% CI 0.42-0.83) and higher odds of educational attainment and school enrolment among males (aOR 2.53, 95% CI 1.59-4.03 and aOR 3.11, 95% CI 1.56-6.19, respectively). CONCLUSIONS: Our study provides evidence that social protection programs are associated with improved educational, sexual and reproductive health and child marriage prevention outcomes among adolescents living in poverty. Implementing and expanding such social protection initiatives could prove instrumental in improving the well-being of vulnerable adolescents. CONTRIBUTIONS: Social protection programs have been increasing in sub-Saharan African countries, playing a pivotal role in poverty reduction, with Lesotho being no exception. Despite the optimistic outlook brought about by the implementation of the National Social Protection Strategy Lesotho I (2014-19) and II (2021-2031), the impact of these programs on some specific outcomes that concern the lives of the most vulnerable adolescents in Lesotho remains to some extent unexplored. Additionally, Lesotho grapples with high rates of HIV, adolescent pregnancy, child marriage and early school dropout, which can further contribute to poor long-term health and social outcomes among adolescents. In this study, we used data from the 2018 Lesotho Violence Against Children and Youth Survey (VACS) to examine the association between receiving social protection and multiple adolescent outcomes: educational, sexual and reproductive. The findings revealed that social protection programs, particularly the existing government-provided cash transfers, are significantly associated with multiple better outcomes among adolescents living in the poorest households in Lesotho. Such cash transfer schemes in Lesotho are associated with improved sexual and reproductive health outcomes for adolescent females, including reduced child marriage rates, and improved educational outcomes for males. These findings indicate that government-led social protection programmes are positively associated with favourable outcomes that can improve the quality of life for adolescents in resource-limited settings.

Advanced Ultrasound Energy Transfer Technologies using Metamaterial Structures.

Wireless energy transfer (WET) based on ultrasound-driven generators with enormous beneficial functions, is technologically in progress by the valuation of ultrasonic metamaterials (UMMs) in science and engineering domains. Indeed, novel metamaterial structures can develop the efficiency of mechanical and physical features of ultrasound energy receivers (US-ETs), including ultrasound-driven piezoelectric and triboelectric nanogenerators (US-PENGs and US-TENGs) for advantageous applications. This review article first summarizes the fundamentals, classification, and design engineering of UMMs after introducing ultrasound energy for WET technology. In addition to addressing using UMMs, the topical progress of innovative UMMs in US-ETs is conceptually presented. Moreover, the advanced approaches of metamaterials are reported in the categorized applications of US-PENGs and US-TENGs. Finally, some current perspectives and encounters of UMMs in US-ETs are offered. With this objective in mind, this review explores the potential revolution of reliable integrated energy transfer systems through the transformation of metamaterials into ultrasound-driven active mediums for generators.

Cholesterol transfer to high-density lipoprotein in obesity and the effects of weight loss after bariatric surgery.

Obesity increases serum triglycerides and decreases high-density lipoprotein cholesterol (HDL-C). The objective is to explore some functions of HDL, cholesterol transfers and antioxidant, in subjects with grade I (G1-OB) and III (G3-OB) obesity and effects of bariatric surgery on G3-OB. Fifteen G3-OB patients (43 ± 6 years, BMI 49 ± 3 kg/m2) were studied before and 1 year after bariatric surgery; 15 G1-OB (32 ± 2 years, 32 ± 2 kg/m2) and 15 normal weight (NW) (38 ± 6 years, 22 ± 1 kg/m2) were also studied. HDL diameter, cholesterol transfer to HDL and antioxidant capacity of HDL were determined. G3-OB had higher triglycerides and lower HDL-C; G1-OB had higher triglycerides than NW but HDL-C was equal. Compared to NW, HDL size was smaller in G3-OB but equal in G1-OB. One year after bariatric surgery, BMI and triglycerides of G3-OB decreased (p < .0001 and p = .0012, respectively) and HDL-C increased (p < .0001), equalling of NW group. Antioxidant capacity and cholesterol transfers were not different in groups and were unchanged 1 year after bariatric surgery in G3-OB. HDL antioxidant capacity and transfer of cholesterol to HDL were not defective in obesity despite HDL-C reduction and smaller HDL size. In addition, pronounced weight loss by bariatric surgery did not change those protective functions.

Sciatic and tibial neuropathies.

The sciatic nerve is the body's largest peripheral nerve. Along with their two terminal divisions (tibial and fibular), their anatomic location makes them particularly vulnerable to trauma and iatrogenic injuries. A thorough understanding of the functional anatomy is required to adequately localize lesions in this lengthy neural pathway. Proximal disorders of the nerve can be challenging to precisely localize among a range of possibilities including lumbosacral pathology, radiculopathy, or piriformis syndrome. A correct diagnosis is based upon a thorough history and physical examination, which will then appropriately direct adjunctive investigations such as imaging and electrodiagnostic testing. Disorders of the sciatic nerve and its terminal branches are disabling for patients, and expert assessment by rehabilitation professionals is important in limiting their impact. Applying techniques established in the upper extremity, surgical reconstruction of lower extremity nerve dysfunction is rapidly improving and evolving. These new techniques, such as nerve transfers, require electrodiagnostic assessment of both the injured nerve(s) as well as healthy, potential donor nerves as part of a complete neurophysiological examination.

Protocol implementation during the COVID-19 pandemic: experiences from a randomized trial of stress ulcer prophylaxis.

BACKGROUND: During the COVID-19 pandemic, many intensive care units (ICUs) halted research to focus on COVID-19-specific studies. OBJECTIVE: To describe the conduct of an international randomized trial of stress ulcer prophylaxis (Re-Evaluating the Inhibition of Stress Erosions in the ICU [REVISE]) during the pandemic, addressing enrolment patterns, center engagement, informed consent processes, data collection, a COVID-specific substudy, patient transfers, and data monitoring. METHODS: REVISE is a randomized trial among mechanically ventilated patients, comparing pantoprazole 40 mg IV to placebo on the primary efficacy outcome of clinically important upper gastrointestinal bleeding and the primary safety outcome of 90-day mortality. We documented protocol implementation status from March 11th 2020-August 30th 2022. RESULTS: The Steering Committee did not change the scientific protocol. From the first enrolment on July 9th 2019 to March 10th 2020 (8 months preceding the pandemic), 267 patients were enrolled in 18 centers. From March 11th 2020-August 30th 2022 (30 months thereafter), 41 new centers joined; 59 were participating by August 30th 2022 which enrolled 2961 patients. During a total of 1235 enrolment-months in the pandemic phase, enrolment paused for 106 (8.6%) months in aggregate (median 3 months, interquartile range 2;6). Protocol implementation involved a shift from the a priori consent model pre-pandemic (188, 58.8%) to the consent to continue model (1615, 54.1%, p < 0.01). In one new center, an opt-out model was approved. The informed consent rate increased slightly (80.7% to 85.0%, p = 0.05). Telephone consent encounters increased (16.6% to 68.2%, p < 0.001). Surge capacity necessitated intra-institutional transfers; receiving centers continued protocol implementation whenever possible. We developed a nested COVID-19 substudy. The Methods Centers continued central statistical monitoring of trial metrics. Site monitoring was initially remote, then in-person when restrictions lifted. CONCLUSION: Protocol implementation adaptations during the pandemic included a shift in the consent model, a sustained high consent rate, and launch of a COVID-19 substudy. Recruitment increased as new centers joined, patient transfers were optimized, and monitoring methods were adapted.

Is the African Vaccine Manufacturing Accelerator a decoupling mechanism?

This article explores how the African Vaccine Manufacturing Accelerator can support the sustainable production of vaccines in Africa. It highlights the value of the accelerator in relation to the Regional Vaccine Manufacturing Collaborative. The author proposes that this novel financing instrument should be well-designed and implemented in line with the targets of the Partnerships for African Vaccine Manufacturing. It should not be a decoupling tool to appease the institutional environment of the global vaccine market, but a sustainable demonstration of the goodwill and commitment of political and technical leaders to ensure equitable access to routine and epidemic-related vaccines in Africa.

Unplanned transfer to acute care during inpatient geriatric rehabilitation: incidence, risk factors, and associated short-term outcomes.

BACKGROUND: Information is scarce on unplanned transfers from geriatric rehabilitation back to acute care despite their potential impact on patients' functional recovery. This study aimed 1) to determine the incidence rate and causes of unplanned transfers; 2) to compare the characteristics and outcomes of patients with and without unplanned transfer. METHODS: Consecutive stays (n = 2375) in a tertiary geriatric rehabilitation unit were included. Unplanned transfers to acute care and their causes were analyzed from discharge summaries. Data on patients' socio-demographics, health, functional, and mental status; length of stay; discharge destination; and death, were extracted from the hospital database. Bi- and multi-variable analyses investigated the association between patients' characteristics and unplanned transfers. RESULTS: One in six (16.7%) rehabilitation stays was interrupted by a transfer, most often secondary to infections (19.3%), cardiac (16.8%), abdominal (12.7%), trauma (12.2%), and neurological problems (9.4%). Older patients (AdjORage≥85: 0.70; 95%CI: 0. 53-0.94, P = .016), and those admitted for gait disorders (AdjOR: 0.73; 95%CI: 0.53-0.99, P = .046) had lower odds of transfer to acute care. In contrast, men (AdjOR: 1.71; 95%CI: 1.29-2.26, P < .001), patients with more severe disease (AdjORCIRS: 1.05; 95%CI: 1.02-1.07, P < .001), functional impairment before (AdjOR: 1.69; 95%CI: 1.05-2.70, P = .029) and at rehabilitation admission (AdjOR: 2.07; 95%CI: 1.56- 2.76, P < .001) had higher odds of transfer. Transferred patients were significantly more likely to die than those without transfer (AdjOR 13.78; 95%CI: 6.46-29.42, P < .001) during their stay, but those surviving had similar functional performance and rate of home discharge at the end of the stay. CONCLUSION: A significant minority of patients experienced an unplanned transfer that potentially interfered with their rehabilitation and was associated with poorer outcomes. Men, patients with more severe disease and functional impairment appear at increased risk. Further studies should investigate whether interventions targeting these patients may prevent unplanned transfers and modify associated adverse outcomes.

Group 2 innate lymphoid cells are key in lipid transfer protein allergy pathogenesis.

Background: Immunopathology in food allergy is characterized by an uncontrolled type 2 immune response and specific-IgE production. Recent studies have determined that group 2 innate lymphoid cells (ILC2) participate in the food allergy pathogenic mechanism and their severity. Our objective was to investigate the role of ILC2 in peach-allergic patients due to non-specific lipid transfer protein (Pru p 3) sensitization. Methods: The immune response in peripheral blood mononuclear cells was characterized in lipid transfer protein-allergic patients and healthy controls. We have analyzed the Pru p 3 uptake on ILC2, the expression of costimulatory molecules, and their involvement on the T-cell proliferative response and cytokine production under different experimental conditions: cytokines involved in group 2 innate lymphoid cell activation (IL-33 and IL-25), Pru p 3 as main food allergen, and the combination of both components (IL-33/IL-25+Pru p 3) using cell sorting, EliSpot, flow cytometry, and confocal microscopy. Results: Our results show that Pru p 3 allergen is taken up by group 2 innate lymphoid cells, regulating their costimulatory molecule expression (CD83 and HLA-DR) depending on the presence of Pru p 3 and its combination with IL-33/IL-25. The Pru p 3-stimulated ILC2 induced specific GATA3+Th2 proliferation and cytokine (IL-4, IL-5, and IL-13) production in lipid transfer protein-allergic patients in a cell contact-dependent manner with no changes in Tbet+Th1- and FOXP3+Treg cell differentiation. Conclusions: The results indicate that in lipid transfer protein-allergic patients, the responsible allergen, Pru p 3, interacts with group 2 innate lymphoid cells, promoting a Th2 cell response. Our results might be of interest in vivo, as they show a role of group 2 innate lymphoid cells as antigen-presenting cells, contributing to the development of food allergy. Consequently, group 2 innate lymphoid cells may be considered as potential therapeutic targets.

Fusogenic vesicular stomatitis virus combined with natural killer T cell immunotherapy controls metastatic breast cancer.

BACKGROUND: Metastatic breast cancer is a leading cause of cancer death in woman. Current treatment options are often associated with adverse side effects and poor outcomes, demonstrating the need for effective new treatments. Immunotherapies can provide durable outcomes in many cancers; however, limited success has been achieved in metastatic triple negative breast cancer. We tested whether combining different immunotherapies can target metastatic triple negative breast cancer in pre-clinical models. METHODS: Using primary and metastatic 4T1 triple negative mammary carcinoma models, we examined the therapeutic effects of oncolytic vesicular stomatitis virus (VSVΔM51) engineered to express reovirus-derived fusion associated small transmembrane proteins p14 (VSV-p14) or p15 (VSV-p15). These viruses were delivered alone or in combination with natural killer T (NKT) cell activation therapy mediated by adoptive transfer of α-galactosylceramide-loaded dendritic cells. RESULTS: Treatment of primary 4T1 tumors with VSV-p14 or VSV-p15 alone increased immunogenic tumor cell death, attenuated tumor growth, and enhanced immune cell infiltration and activation compared to control oncolytic virus (VSV-GFP) treatments and untreated mice. When combined with NKT cell activation therapy, oncolytic VSV-p14 and VSV-p15 reduced metastatic lung burden to undetectable levels in all mice and generated immune memory as evidenced by enhanced in vitro recall responses (tumor killing and cytokine production) and impaired tumor growth upon rechallenge. CONCLUSION: Combining NKT cell immunotherapy with enhanced oncolytic virotherapy increased anti-tumor immune targeting of lung metastasis and presents a promising treatment strategy for metastatic breast cancer.

Optimizing Interhospital Transfers in Orthopedics and Trauma Surgery: Challenges, Insights, and Proposals for Standardized Care in Germany.

BACKGROUND: Germany's high density of under-equipped hospitals and anticipated surge in orthopedic and trauma surgery-related diseases by 2030, combined with personnel shortages, are expected to increase patient transfers between hospitals, an issue that urgently needs standardized protocols. Despite some existing cooperative agreements, such as between joint-replacement centers or within the Trauma Network DGU®, these measures do not adequately address the full range of patient-transfer cases, including those due to a lack of specialization or staff shortages, resulting in delayed treatment and potential health risks. This study aims to dissect the intricacies of interhospital transfers in orthopedics and trauma surgery across Germany, focusing on understanding the underlying reasons for transfers, comparing the operational structures of small and large hospitals, and laying the groundwork for future standardized protocols to enhance patient care. MATERIAL AND METHODS: A cross-sectional study was conducted in the form of an online survey via SoSci Survey, which was directed at orthopedic surgeons and trauma surgeons working in hospitals in Germany. The 22-question survey gathered information on participants' clinic roles, departmental details, transfer processes, frequent diagnoses, perceptions of transfer quality, and improvement areas. The survey was sent to orthopedic and trauma surgeons in Germany by the specialist society. The data were analyzed using descriptive and inferential statistics to ensure a comprehensive insight into interhospital transfer practices. RESULTS: The study involved 152 participants from various hospital ranks and located in different hospital sizes and types across rural and urban areas. A significant difference was observed between the care structures of basic/regular care and central/maximum care hospitals, especially regarding the available facilities and specialties. These findings suggest improvements such as better patient documentation, increased digital communication, optimized patient distribution, and standardization of transfer requests, among others. CONCLUSIONS: This study highlights the urgent need for improved protocols and resource allocation to eliminate inequalities in transfers between hospitals in orthopedics and trauma surgery in Germany.

Cash Transfers and After-School Programs: A Randomized Controlled Trial for Young Men at Risk of Violence Exposure in Wilmington, Delaware.

We conducted a randomized controlled trial to determine whether an after-school program paired with a cash transfer (a conditional cash transfer) or a cash transfer alone (an unconditional cash transfer) can help improve health and economic outcomes for young men between the ages of 14 and 17 whose parents have low incomes and who live in neighborhoods with high crime rates. We find that receiving the cash transfer alone was associated with an increase in healthy behaviors (one of our primary outcome composite measures) and that the cash transfer paired with after-school programming was associated with an improvement in the financial health of participants (one of our secondary outcome composite measures). We find no differences in spending on alcohol, marijuana, cigarettes, or other drugs between either the treatment group and the control group. Neither the cash transfer alone nor the programming plus cash transfer had statistically significant effects on our other primary composite measures (physical and mental health or school attendance and disciplinary actions), or our other secondary composite measures (criminal justice engagement or social supports) but in most cases, confidence intervals were too large to rule out meaningful effects. Results suggest that cash transfers hold promise to improve the health of youth without any indication of any adverse effects.

Miracle friends and miracle money in California: a mixed-methods experiment of social support and guaranteed income for people experiencing homelessness.

BACKGROUND: This paper describes the protocols for a randomized controlled trial using a parallel-group trial design that includes an intervention designed to address social isolation and loneliness among people experiencing homelessness known as Miracle Friends and an intervention that combines Miracles Friends with an economic poverty-reduction intervention known as Miracle Money. Miracle Friends pairs an unhoused person with a volunteer "phone buddy." Miracle Money provides guaranteed basic income of $750 per month for 1 year to Miracle Friends participants. The study will examine whether either intervention reduces social isolation or homelessness compared to a waitlist control group. METHODS: Unhoused individuals who expressed interest in the Miracle Friends program were randomized to either receive the intervention or be placed on a waitlist for Miracle Friends. Among those randomized to receive the Miracle Friends intervention, randomization also determined whether they would be offered Miracle Money. The possibility of receiving basic income was only disclosed to study participants if they were randomly selected and participated in the Miracle Friends program. All study participants, regardless of assignment, were surveyed every 3 months for 15 months. RESULTS: Of 760 unhoused individuals enrolled in the study, 256 were randomized to receive Miracle Friends, 267 were randomized to receive Miracle Money, and 237 were randomized to the waitlist control group. In the two intervention groups, 360 of 523 unhoused individuals were initially matched to a phone buddy. Of the 191 study participants in the Miracle Money group who had been initially matched to a volunteer phone buddy, 103 were deemed to be participating in the program and began receiving monthly income. DISCUSSION: This randomized controlled trial will determine whether innovative interventions involving volunteer phone support and basic income reduce social isolation and improve housing outcomes for people experiencing homelessness. Although we enrolled unhoused individuals who initially expressed interest in the Miracle Friends program, the study team could not reach approximately 30% of individuals referred to the study. This may reflect the general lack of stability in the lives of people who are unhoused or limitations in the appeal of such a program to some portion of the unhoused population. TRIAL REGISTRATION: ClinicalTrials.gov NCT05408884 (first submitted on May 26, 2022).

Are geriatric transfer patients with traumatic brain injury at risk for worse outcomes compared to non-geriatric? Propensity-matched study.

OBJECTIVE: To compare outcomes between geriatric and non-geriatric patients with traumatic brain injury (TBI) transferred to trauma center and effects of anticoagulants/antiplatelets (AC/AP) and reversal therapy. METHODS: A retrospective review of 1,118 patients with TBI transferred from acute care facilities to level 1 trauma center compared in groups: geriatric versus non-geriatric, geriatric with AC/AP therapy versus without, and geriatric AC/AP with AC/AP reversal therapy versus without. RESULTS: Patients with TBI constituted 54.4% of trauma transfers. Mean transfer time was 3.9 h. Propensity matched by Injury Severity Score and Abbreviated Injury Score (AIS) head geriatric compared to non-geriatric patients had more AC/AP use (53.9% vs 8.8%), repeat head computed tomography (93.7% vs 86.1%), intensive care unit (ICU) admissions (57.4% vs 45.7%) and mortality (9.8% vs 3.2%), all p < 0.004. Patients on AC/AP versus without had more ICU admissions (69.1% vs 51.8%, p < 0.001). Patients with AC/AP reversals compared to without reversals had more AIS head 5 (32.0% vs 13.1%), brain surgeries (17.8% vs 3.5%) and ICU admissions (84.8% vs 57.1%), all p < 0.001. CONCLUSION: TBI constituted half of trauma transfers and 10% required surgery. Based on higher ICU admissions, mortality, and prevalence of AC/AP therapy requiring reversal, geriatric patients with TBI on anticoagulants/antiplatelets should be considered for direct trauma center admission.
