RESUMEN
As homelessness remains an urgent public health crisis in the United States, specific programs in the US Department of Veterans Affairs (VA) system may serve as a roadmap for addressing it. We examine lessons learned from the first decade (2012-2022) of the Supportive Services for Veteran Families (SSVF) program, a cornerstone in the VA continuum of homeless services aimed at both preventing homelessness among those at risk and providing rapid rehousing for veterans and their families who are currently experiencing homelessness. Drawing on information from annual reports and other relevant literature, we have identified 3 themes of SSVF that emerged as features to comprehensively deliver support for homeless veterans and their families: (1) responsiveness and flexibility, (2) coordination and integration, and (3) social resource engagement. Using these strategies, SSVF reached nearly three quarters of a million veterans and their families in its first decade, thereby becoming one of the VA's most substantial programmatic efforts designed to address homelessness. We discuss how each feature might apply to addressing homelessness in the general population as well as future research directions.

BACKGROUND: Melanoma disease patterns vary with patient age. AIM: To evaluate sentinel lymph node biopsy (SLNB) in managing melanoma at differing patient ages. METHODS: Online prediction tools were applied to compare SLNB positivity (SLNB+) and survival risk at patient ages 20-80. Tübingen melanoma data were used to determine variations in the hazard ratio of SLNB+ for mortality at different patient ages. RESULTS: Regardless of tumour thickness, predicted SLNB+ rates were markedly higher than mortality rates for 20-year-old patients. For 80-year-old patients, it is the opposite. DISCUSSION: If 1000 20-year-olds with a 0.4 mm thickness non-ulcerated melanoma underwent SLNB, 100 would likely be positive. If all 100 were to be offered adjuvant drug therapy (ADT), fewer than three more melanoma deaths in those 1000 patients would be avoided. In total, 97 patients would have received medication they may never have needed. If 1000 80-year-olds with a 3 mm thickness non-ulcerated melanoma underwent SLNB, only 40 would likely be positive. In total, 274 patients would be predicted to die of melanoma, 245 being SLNB negative and 29 SLNB+. ADT linked to SLNB+ could deny treatment to 89% of these high-risk patients. LIMITATIONS: The authors relied on published risk data. CONCLUSION: SLNB has poor specificity at predicting mortality in young melanoma patients and poor sensitivity in older patients. SLNB is not indicated in managing cutaneous melanoma for patients under 40 or over 60 years of age. Many such patients could be managed with wide local excision alone in their clinician's office-based practice. For all cutaneous melanoma patients at all ages, linking ADT to BAUSSS biomarker, (an algorithm of Breslow thickness, age, ulceration, subtype, sex and Site) rather than SLNB+ is likely more appropriate. BAUSSS provides a more accurate melanoma-specific mortality risk assessment for patients without burdening them with added surgery, hospitalization, costs or morbidity risk.

BACKGROUND: This is the first study, to our knowledge, to assess uptake of oral antiviral treatment (OAV) for COVID-19 in the US and assess whether it is reaching recommended groups. OBJECTIVE: The study evaluated uptake among persons of all ages, with emphasis on utilization among individuals ages 65 + who comprise 75% of all COVID-19 deaths. To maximize public health outreach and benefit, we sought to understand reasons for use and non-use of OAV among individuals 65 + with at least mild COVID-19 symptoms. DESIGN: Data were collected from phase 3.5 of the US Census Household Pulse Survey, during three 2022 time periods: June 1-13, June 29-July 11, and July 27-August 8. PARTICIPANTS: Respondents (n = 12,299) were ages 18 + with active or resolved COVID-19 within the last 4 weeks of their survey participation. MAIN MEASURE(S): Comparisons of demographic variables were made for OAV uptake using the chi-square test of independence. A logistic regression was conducted to identify characteristics of participants independently associated with receipt of an OAV. Comparisons were made with chi-square testing, between those ages 65 + with at least mild symptoms who endorsed one of a number of specific reasons for not using OAV. KEY RESULTS: Utilization was low-17.9% of all respondents, 20.5% of respondents ages 50-64, and 33.9% of respondents 65 years and older received guideline-concordant treatment for their infection. Receipt did not differ by income or sex. The average response across the three phases was 5.4%. Most common reasons for not receiving treatment included having minimal symptoms, not thinking that they needed treatment, and not receiving a recommendation from their healthcare provider. CONCLUSIONS: A minority of increased-risk US residents have accessed early therapy for COVID-19 despite being made available without cost. Responses suggest that efforts to improve patient and provider knowledge could improve utilization to mitigate future COVID-19 hospitalizations.

Background: Despite an association between operator volumes and procedural success, there remains an incomplete understanding of the contemporary utilization and procedural volumes for mitral valve transcatheter edge-to-edge repair (MTEER). We aimed to identify annual operator procedural volumes, temporal trends, and geographic variability for MTEER among Medicare patients in the United States (US). Methods: We queried the National Medicare Provider Utilization and Payment Database for a CPT code (33418) specific for MitraClip device from 2015 through 2019. We analyzed annual operator procedural volumes and incidence and identified longitudinal and geographic trends in MTEER utilization. Results: From 2015 through 2019, a total of 27,034 MTEER procedures were performed among Medicare patients in the US. The nationwide incidence increased from 6.2 per 100,000 patients in 2015 to 23.8 per 100,000 patients in 2019, a 283% increase over the study period (Ptrend < 0.001). The incidence of MTEER by state varied by nearly 900% (range 5.5 to 54.9 per 100,000 person-years). In 2019, the mean annual MTEER operator annual volume was 9.1 MTEER procedures and had grown from 6.2 per year in 2015. Conclusions: In this nationwide study of Medicare beneficiaries in the United States, we identified a significant and sustained increase in the utilization of MTEER devices and operators and growth in annual procedural volumes from 2015 through 2019 with considerable variability in utilization by state. Further studies are needed to understand the clinical impact of variability in utilization and the optimal procedural volumes to ensure high efficacy outcomes and maintain critical access to MTEER therapies.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic highlighted the challenges of effective emergency risk communication (ERC) to protect public health, including the difficulty in tackling the spread of inaccurate information. This study aimed to understand those challenges and potential solutions by interviewing leading government spokespersons and their advisors from around the world with experience during large scale emergencies. Interviews were conducted with 27 individuals representing governments from 19 countries across five continents. Thematic analysis, using both a deductive and inductive approach, organized and identified salient themes and patterns that emerged from the interview data. RESULTS: The thematic analysis of the interviews' data led to the identification of 9 principles of communication: 1) Timeliness, 2) Transparency, 3) Coordination, 4) Accuracy and Consistency, 5) Accountability and Integrity, 6) Independence from politics, 7) Responsiveness, 8) Equity, 9) Trust and Empathy. We also developed 36 recommendations actionable by government agencies to enhance the practice of the 9 principles. Examples include the need for: proactive communication strategies, permanent communication task forces integrated into preparedness and response efforts, robust processes to enhance open discussion of controversial topics within government agencies, clarification of how various branches of government coordinate to oversee specific aspects of the overall communication, and development of relationships across public and private entities ahead of a crisis. CONCLUSIONS: Our findings suggest key practical recommendations for leaders of government agencies to enhance ERC capabilities going forward. Before a crisis, they must constantly review internal processes and integrate ERC functions into overall communication planning efforts. During a crisis, they must coordinate roles and responsibilities across branches of governments, strive to communicate to a range of populations to uphold equity, maintain transparency by avoiding information voids on controversial issues and build trust by building relationships with a variety of community leaders. After a crisis, government agencies should continue the practice of social listening to hear more about the public's informational needs, strengthen civic participation processes, and understand how an always evolving information environment can best be leveraged during future crises.

In this commentary, we review the evidence concerning associations between religious service attendance and subsequent health and wellbeing outcomes. The evidence base for a link between religious service attendance and health has increased substantially over the past 2 decades. The interpretation and implications of this research require careful consideration (Am J Epidemiol. 2022;191(1):20-30). It would be inappropriate to universally promote service attendance solely on the grounds of the associations with health. Nevertheless, a more nuanced approach, within both clinical care and public health, may be possible-one that encouraged participation in religious community for those who already positively self-identified with a religious or spiritual tradition and encouraged other forms of community participation for those who did not. Discussion is given to potential future research directions and the challenges and opportunities for promotion efforts by the public health community.

BACKGROUND: Eliminating health disparities among different segments of the US population is an overarching goal of the US Healthy People 2020 objectives. OBJECTIVE: Examine changes in educational, rural-urban, and racial disparities in premature mortality during the past 10 years. DESIGN AND PARTICIPANTS: Descriptive analysis of US mortality data from 2007 to 2017. MAIN MEASURES: Relative and absolute rural-urban, educational attainment, and Black-White disparities in premature mortality for all-cause and top 10 causes of death among persons ages 25-74 years, estimated as rate ratios and rate differences between ≤12 and ≥16 years of education, rural versus urban, and non-Hispanic Black (Black) versus non-Hispanic White (White), respectively, in 2007 and 2017. KEY RESULTS: During 2007-2017, mortality rates in persons aged 25-74 years in the USA increased for several leading causes of death, especially in persons with <16 years of education, rural residents, and White people. As a result, disparity in mortality between 2007 and 2017 widened on both relative and absolute scales for all-cause and for 6 of the top 10 causes of death by education and for all-cause and for 9 of the top 10 causes by rural/urban residence. In contrast, Black-White disparities narrowed for all-cause and for all 7 causes that Black people had a higher rate than White people. For all-cause mortality for example, absolute disparities in the number of deaths per 100,000 person-years between 2007 and 2017 increased from 454.0 (95%CI, 446.0-462.1) to 542.7 (535.6-549.7) for educational attainment and from 85.8 (82.8-88.8) to 140.5 (137.6-143.4) for rural versus urban; in contrast, absolute Black-White disparity decreased from 315.3 (311.0-319.7) to 221.7 (218.1-225.3). CONCLUSIONS: Educational and rural-urban disparities in premature mortality widened, whereas Black-White disparities narrowed in the USA between 2007 and 2017, though overall rates remained considerably higher in Black people.

OBJECTIVES: To evaluate transcatheter aortic valve replacement (TAVR) operator procedural volumes, and describe temporal and geographic trends. BACKGROUND: TAVR is the standard of care for most patients with severe symptomatic aortic stenosis. Despite an association between operator procedural volume and outcomes, nationwide TAVR operator volumes have been incompletely described. METHODS: We queried the National Medicare Provider Utilization and Payment Database for transfemoral TAVRs from 2014 to 2018. Annual operator volume, state and regional volumes, and longitudinal trends were extracted and analyzed using descriptive statistics. RESULTS: In 2018, the mean annual operator volume was 23.6 TAVRs. The highest 1% of operators by volume performed 7.6% of total TAVR procedures in the United States, while 35.7% of operators performed 10 or fewer TAVRs per year. From 2014 to 2018, there was a 53.9% annualized increase in TAVRs, and the mean annual volume per operator grew from 12.5 to 23.6. There was more than five-fold variability in the density of operators (range 0.35-1.79 operators per 100,000 population) and mean operator volume by state (range 14.2-52.4 TAVRs per operator). CONCLUSIONS: In this nationally representative study of operators performing transfemoral TAVRs among Medicare patients, we found the mean annual volume of TAVR in 2018 to be 23.6 and has increased since 2014. There was considerable variability in operator density and procedural volumes, with a significant proportion of operators performing 10 or fewer TAVRs per year. Ambiguity remains in regard to the optimal balance of procedural requirements to sustain high efficacy outcomes and ensure critical access to TAVR therapies.

Reptiles are increasingly of conservation concern due to their susceptibility to habitat loss, emerging disease, and harvest in the wildlife trade. However, reptile populations are often difficult to monitor given the frequency of crypsis in their life history. This difficulty has left uncertain the conservation status of many species and the efficacy of conservation actions unknown. Environmental DNA (eDNA) surveys consistently elevate the detection rate of species they are designed to monitor, and while their use is promising for terrestrial reptile conservation, successes in developing such surveys have been sparse. We tested the degree to which inclusion of surface and soil eDNA sampling into conventional artificial-cover methods elevates the detection probability of a small, cryptic terrestrial lizard, Scincella lateralis. The eDNA sampling of cover object surfaces with paint rollers elevated per sample detection probabilities for this species 4-16 times compared with visual surveys alone. We readily detected S. lateralis eDNA under cover objects up to 2 weeks after the last visual detection, and at some cover objects where no S. lateralis were visually observed in prior months. With sufficient sampling intensity, eDNA testing of soil under cover objects produced comparable per sample detection probabilities as roller surface methods. Our results suggest that combining eDNA and cover object methods can considerably increase the detection power of reptile monitoring programs, allowing more accurate estimates of population size, detection of temporal and spatial changes in habitat use, and tracking success of restoration efforts. Further research into the deposition and decay rates of reptile eDNA under cover objects, as well as tailored protocols for different species and habitats, is needed to bring the technique into widespread use.
El interés por la conservación de los reptiles es cada vez mayor debido a su susceptibilidad ante la pérdida del hábitat, enfermedades emergentes y la captura para el mercado de fauna. Sin embargo, las poblaciones de reptiles son difíciles de monitorear por lo frecuente que es la cripsis en sus historias de vida. Esta dificultad deja incierto el estado de conservación de muchas especies y desconocida la eficacia de las acciones de conservación. Los censos de ADN ambiental (DNAa) elevan sistemáticamente la tasa de detección de las especies que monitorean, y aunque su uso es prometedor para la conservación de los reptiles terrestres, han sido escasos los éxitos en el desarrollo de dichos censos. Analizamos el grado al que la inclusión del muestreo de DNAa superficial y del suelo a los métodos convencionales de cobertura artificial eleva la probabilidad de detección de una pequeña lagartija terrestre críptica: Scincella lateralis. El muestreo de DNAa de las superficies con cobertura de objetos con rodillos de pintura elevó las probabilidades de detección por muestra para esta especie 4-16 veces más que los censos visuales. Detectamos fácilmente el DNAa de S. lateralis bajo los objetos de cubierta hasta dos semanas después de la última detección visual y en algunos objetos de cubierta en donde no se había observado en los meses previos a S. lateralis. Con suficiente intensidad de muestreo, el análisis de DNAa del suelo bajo objetos de cubierta produjo probabilidades de detección por muestra comparables como métodos de rodillo superficial. Nuestros resultados sugieren que la combinación del DNAa y los métodos de objetos de cobertura puede incrementar considerablemente el poder de detección de los programas de monitoreo de reptiles, lo que permite estimaciones más precisas del tamaño poblacional, detección de los cambios espaciales y temporales en el uso de hábitat y el éxito de rastreo de los esfuerzos de restauración. Además, se necesita la investigación sobre las tasas de depósito y descomposición del DNAa de reptiles bajo objetos de cubierta, así como los protocolos hechos para diferentes especies y hábitats, para que la técnica entre al uso difundido.

BACKGROUND: Dementia is a leading cause of death in developed nations. Despite an often distressing and symptom laden end of life, there are systematic barriers to accessing palliative care in older people dying of dementia. Evidence exists that 70% of people living with severe dementia attend an emergency department (ED) in their last year of life. The aim of this trial is to test whether a Carer End of Life Planning Intervention (CELPI), co-designed by consumers, clinicians and content specialists, improves access to end of life care for older people with severe dementia, using an ED visit as a catalyst for recognising unmet needs and specialist palliative care referral where indicated. METHODS: A randomised controlled trial (RCT) enrolling at six EDs across three states in Australia will be conducted, enrolling four hundred and forty dyads comprising a person with severe dementia aged ≥ 65 years, and their primary carer. Participants will be randomly allocated to CELPI or the control group. CELPI incorporates a structured carer needs assessment and referral to specialist palliative care services where indicated by patient symptom burden and needs assessment. The primary outcome measure is death of the person with dementia in the carer-nominated preferred location. Secondary outcomes include carer reported quality of life of the person dying of dementia, hospital bed day occupancy in the last 12 months of life, and carer stress. An economic evaluation from the perspective of a health funder will be conducted. DISCUSSION: CELPI seeks to support carers and provide optimal end of life care for the person dying of dementia. This trial will provide high level evidence as to the clinical and cost effectiveness of this intervention. TRIAL REGISTRATION: ACTRN12622000611729 registered 22/04/2022.

Importance: Despite growing evidence, the role of spirituality in serious illness and health has not been systematically assessed. Objective: To review evidence concerning spirituality in serious illness and health and to identify implications for patient care and health outcomes. Evidence Review: Searches of PubMed, PsycINFO, and Web of Science identified articles with evidence addressing spirituality in serious illness or health, published January 2000 to April 2022. Independent reviewers screened, summarized, and graded articles that met eligibility criteria. Eligible serious illness studies included 100 or more participants; were prospective cohort studies, cross-sectional descriptive studies, meta-analyses, or randomized clinical trials; and included validated spirituality measures. Eligible health outcome studies prospectively examined associations with spirituality as cohort studies, case-control studies, or meta-analyses with samples of at least 1000 or were randomized trials with samples of at least 100 and used validated spirituality measures. Applying Cochrane criteria, studies were graded as having low, moderate, serious, or critical risk of bias, and studies with serious and critical risk of bias were excluded. Multidisciplinary Delphi panels consisting of clinicians, public health personnel, researchers, health systems leaders, and medical ethicists qualitatively synthesized and assessed the evidence and offered implications for health care. Evidence-synthesis statements and implications were derived from panelists' qualitative input; panelists rated the former on a 9-point scale (from "inconclusive" to "strongest evidence") and ranked the latter by order of priority. Findings: Of 8946 articles identified, 371 articles met inclusion criteria for serious illness; of these, 76.9% had low to moderate risk of bias. The Delphi panel review yielded 8 evidence statements supported by evidence categorized as strong and proposed 3 top-ranked implications of this evidence for serious illness: (1) incorporate spiritual care into care for patients with serious illness; (2) incorporate spiritual care education into training of interdisciplinary teams caring for persons with serious illness; and (3) include specialty practitioners of spiritual care in care of patients with serious illness. Of 6485 health outcomes articles, 215 met inclusion criteria; of these, 66.0% had low to moderate risk of bias. The Delphi panel review yielded 8 evidence statements supported by evidence categorized as strong and proposed 3 top-ranked implications of this evidence for health outcomes: (1) incorporate patient-centered and evidence-based approaches regarding associations of spiritual community with improved patient and population health outcomes; (2) increase awareness among health professionals of evidence for protective health associations of spiritual community; and (3) recognize spirituality as a social factor associated with health in research, community assessments, and program implementation. Conclusions and Relevance: This systematic review, analysis, and process, based on highest-quality evidence available and expert consensus, provided suggested implications for addressing spirituality in serious illness and health outcomes as part of person-centered, value-sensitive care.

BACKGROUND: Sustained high levels of astronaut cognitive performance are a prerequisite for mission success. A neuropsychological battery of 10 brief cognitive tests (Cognition) covering a range of cognitive domains was specifically developed for high performing astronauts to objectively assess cognitive performance. Extended mission durations require repeated cognitive testing and thus high acceptability of the Cognition software to the astronaut population. The aim of this qualitative study was to evaluate acceptability of Cognition to astronauts and astronaut surrogate populations. METHODS: Cognition was administered repeatedly to N=87 subjects (mean age ±SD 35.1 ±8.7 years, 52.8% male) on a laptop or iPad across five individual studies on the International Space Station or in space analog environments on Earth. Following completion of each study, participants were interviewed regarding their experience using Cognition in a semi-structured debrief. Participant comments were analyzed using a qualitative conventional content analysis approach. RESULTS: The majority of participants' comments (86.1%) were coded as positive or neutral in valence, with most positive comments relating to software usability, engagement, and overall design. Among the 10 Cognition tests, subjects liked the Visual Object Learning Test most (28 likes, 32.2% of participants), while the Emotion Recognition Test was liked least (44 dislikes, 50.6% of participants). Some subjects (36.8%) were frustrated with the level of difficulty of some of the 10 Cognition tests, especially during early administrations, which was by design to avoid ceiling effects in repeated administrations of high-performers. Technical difficulties were rare (20.7% of participants), and most often observed in environments with restricted internet access. Most participants (82.3% of those who commented) liked the feedback provided by Cognition after each test, which includes a graph showing performance history. CONCLUSION: Cognition was found to be acceptable to astronaut and astronaut-surrogate populations across a variety of settings and mission durations. Participant feedback provided was used to further improve Cognition and increase its acceptability during sustained space missions.
RESUMEN
BACKGROUND: Hypoattenuating leaflet thickening (HALT), the radiographic manifestation of transcatheter heart valve thrombosis, is commonly identified following transcatheter aortic valve replacement (TAVR) and associated with increased risk of stroke and structural valve deterioration. While anticoagulation effectively resolves HALT, routine use remains controversial. We aimed to identify hemodynamic, anatomic, and comorbid predictors of HALT. METHODS: We evaluated consecutive patients with severe aortic stenosis who underwent TAVR with Edwards SAPIEN 3 bioprosthesis at a single center between June 1, 2018 and October 30, 2019. Patients on anticoagulation and those receiving valve-in-valve were excluded. Clinically driven computed tomography (CT) imaging was performed to assess for HALT at the discretion of the treating valve team. RESULTS: A total of 78 patients with a mean age of 78 ± 10 years and STS risk score 5.5 ± 3.3% were analyzed. HALT was identified in 11 (14.1%) patients. Compared to controls, those with HALT had smaller annular areas, 435 ± 57 mm2 vs. 489 ± 79 mm2 (p = .032), but received comparable size valves. In multivariate regression, valve oversizing by more than 20% was associated with increased risk of HALT, OR 23.5, 95% CI 2.5-223, (p = .006). After initiation of anticoagulation, patients with HALT had similar rates of stroke, major bleeding, and all-cause mortality out to an average of 243 days. CONCLUSIONS: In this pragmatic study of patients undergoing TAVR with SAPIEN 3 valves, we report the novel finding that oversizing by more than 20% was independently associated with increased risk of HALT. These findings warrant confirmation in larger and prospective trials.

Cell growth and division are coordinated, ensuring homeostasis under any given growth condition, with division occurring as cell mass doubles. The signals and controlling circuit(s) between growth and division are not well understood; however, it is known in Escherichia coli that the essential GTPase Era, which is growth rate regulated, coordinates the two functions and may be a checkpoint regulator of both. We have isolated a mutant of Era that separates its effect on growth and division. When overproduced, the mutant protein Era647 is dominant to wild-type Era and blocks division, causing cells to filament. Multicopy suppressors that prevent the filamentation phenotype of Era647 either increase the expression of FtsZ or decrease the expression of the Era647 protein. Excess Era647 induces complete delocalization of Z rings, providing an explanation for why Era647 induces filamentation, but this effect is probably not due to direct interaction between Era647 and FtsZ. The hypermorphic ftsZ* allele at the native locus can suppress the effects of Era647 overproduction, indicating that extra FtsZ is not required for the suppression, but another hypermorphic allele that accelerates cell division through periplasmic signaling, ftsL*, cannot. Together, these results suggest that Era647 blocks cell division by destabilizing the Z ring.IMPORTANCE All cells need to coordinate their growth and division, and small GTPases that are conserved throughout life play a key role in this regulation. One of these, Era, provides an essential function in the assembly of the 30S ribosomal subunit in Escherichia coli, but its role in regulating E. coli cell division is much less well understood. Here, we characterize a novel dominant negative mutant of Era (Era647) that uncouples these two activities when overproduced; it inhibits cell division by disrupting assembly of the Z ring, without significantly affecting ribosome production. The unique properties of this mutant should help to elucidate how Era regulates cell division and coordinates this process with ribosome biogenesis.

INTRODUCTION: Late lead perforation (LLP), defined as perforation ≥30 days from cardiac implantable electronic device implant, is a rare diagnosis and little data exist regarding management practices and outcomes. The purpose of this study was to evaluate the occurrence, safety, and efficacy of transvenous management of clinically significant LLP. METHODS: The electronic medical records of a single-center tertiary hospital were reviewed for all patients who were referred for LLP or its sequelae. RESULTS: Eleven consecutive patients were identified from October 2011 to December 2018 with clinically significant LLP. Patients most often presented with pericardial symptoms with the exception of one asymptomatic patient. The median time from lead implant to intervention for LLP was 246 days. Nine patients were managed with an initial transvenous approach, with one requiring sternotomy (lead 6.3 years old). Two patients had a surgical approach, one performed at an outside hospital with subsequent death and another had a mini-thoracotomy, but the lead was removed percutaneously with no surgical repair. In this small cohort, there was no association between the lead extending beyond the parietal pericardium and surgical repair (P = .99). CONCLUSION: Our single-center experience suggests that LLP can be initially managed with a cautious transvenous approach in most patients, but intraprocedural ultrasound for pericardial monitoring and a rescue plan with immediate surgical back up is mandatory.

Carbon and oxygen burning reactions, in particular, ^{12}C+^{12}C fusion, are important for the understanding and interpretation of the late phases of stellar evolution as well as the ignition and nucleosynthesis in cataclysmic binary systems such as type Ia supernovae and x-ray superbursts. A new measurement of this reaction has been performed at the University of Notre Dame using particle-γ coincidence techniques with SAND (a silicon detector array) at the high-intensity 5U Pelletron accelerator. New results for ^{12}C+^{12}C fusion at low energies relevant to nuclear astrophysics are reported. They show strong disagreement with a recent measurement using the indirect Trojan Horse method. The impact on the carbon burning process under astrophysical scenarios will be discussed.
RESUMEN
The rare phenomenon of nuclear wobbling motion has been investigated in the nucleus ^{187}Au. A longitudinal wobbling-bands pair has been identified and clearly distinguished from the associated signature-partner band on the basis of angular distribution measurements. Theoretical calculations in the framework of the particle rotor model are found to agree well with the experimental observations. This is the first experimental evidence for longitudinal wobbling bands where the expected signature partner band has also been identified, and establishes this exotic collective mode as a general phenomenon over the nuclear chart.
RESUMEN
"Anchor Institutions"-universities, hospitals, and other large, place-based organizations-invest in their communities as a way of doing business. Anchor "meds" (anchor institutions dedicated to health) that address social needs and social determinants of health have generated considerable community-based activity over the past several decades.Yet to date, virtually no research has analyzed their current status or effect on community health. To assess the current state and potential best practices of anchor meds, we conducted a search of the literature, a review of Web sites and related public documents of all declared anchor meds in the country, and interviews with 14 key informants.We identified potential best practices in adopting, operationalizing, and implementing an anchor mission and using specific social determinants of health strategies, noting early outcomes and lessons learned. Future dedicated research can bring heightened attention to this emerging force for community health.

OBJECTIVE: To describe the number and proportion of accredited, degree-granting institutions with 100% smoke-free and 100% tobacco-free protections across the USA and by state. METHODS: Data on postsecondary education institutions from the US Department of Education National Center for Education Statistics Integrated Postsecondary Education Data System 2015, and smoke-free and tobacco-free campus protections from the American Nonsmokers' Rights Foundation's Smokefree and Tobacco-Free Colleges and Universities List 2017, were integrated to calculate the number and proportion of: (1) smoke-free and tobacco-free accredited, degree-granting institutions and (2) students and staff protected by campus policies and state laws. Campus protections are given a 100% smoke-free designation if smoking is not allowed on campus anywhere, at any time; 100% tobacco-free designations extend smoke-free protections to include non-combustible products such as smokeless tobacco. RESULTS: 823 accredited, degree-granting institutions (16.7%) representing 1816 individual campuses, sites and schools have either 100% smoke-free or 100% tobacco-free protections. An estimated 14.9 million college students (26.9%) and 8.9 million faculty and staff (25.4%) are protected by campus policies and state laws. Only three states and two territories have 100% smoke-free or 100% tobacco-free protections in over half of their institutions; four states and six territories have no known 100% smoke-free or 100% tobacco-free campus protections. CONCLUSIONS: In 2017, just 16.7% of accredited, degree-granting institutions in the USA had 100% smoke-free or 100% tobacco-free protections. Despite progress, more efforts can ensure that students and staff benefit from comprehensive 100% smoke-free and 100% tobacco-free protections at US colleges and universities.

The prevalence of opioid use and misuse has provoked a staggering number of deaths over the past two and a half decades. Much attention has focused on individual risks according to various characteristics and experiences. However, broader social and contextual domains are also essential contributors to the opioid crisis such as interpersonal relationships and the conditions of the community and society that people live in. Despite efforts to tackle the issue, the rates of opioid misuse and non-fatal and fatal overdose remain high. Many call for a broad public health approach, but articulation of what such a strategy could entail has not been fully realised. In order to improve the awareness surrounding opioid misuse, we developed a social-ecological framework that helps conceptualise the multivariable risk factors of opioid misuse and facilitates reviewing them in individual, interpersonal, communal and societal levels. Our framework illustrates the multi-layer complexity of the opioid crisis that more completely captures the crisis as a multidimensional issue requiring a broader and integrated approach to prevention and treatment.
