Using data recorded with the CLEO II and CLEO II.V detector configurations at the Cornell Electron Storage Rings, we report the first observation and mass measurement of the Sigma(*+)(c) charmed ...baryon, and an updated measurement of the mass of the Sigma(+)(c) baryon. We find M(Sigma(*+)(c))-M(Lambda(+)(c)) = (231.0+/-1.1+/-2.0) MeV, and M(Sigma(+)(c))-M(Lambda(+)(c)) = (166.4+/-0.2+/-0.3) MeV, where the errors are statistical and systematic, respectively.

We report the first direct measurement of decays of the Λ_{c}^{+} baryon involving the neutron. The analysis is performed using 567 pb^{-1} of e^{+}e^{-} collision data collected at sqrts=4.599 GeV ...with the BESIII detector at the BEPCII collider. We observe the decay Λ_{c}^{+}→nK_{S}^{0}π^{+} and measure the absolute branching fraction to be B(Λ_{c}^{+}→nK_{S}^{0}π^{+})=1.82±0.23(stat)±0.11(syst)%. A comparison to BΛ_{c}^{+}→p(Kover ¯π)^{0} provides an important test of isospin symmetry and final state interactions.
•Physical activity levels are often low after bariatric surgery, despite its importance.•GOALS is a positive psychological/behavioral intervention for exercise after surgery.•The remote intervention ...was feasible and acceptable in a small single-arm trial.•Participants increased physical activity and improved psychological well-being.•GOALS will next be tested in a pilot randomized controlled trial.
Physical activity promotes health and longevity after metabolic/bariatric surgery (MBS), but most patients do not meet recommended levels. The Gaining Optimism After weight Loss Surgery (GOALS) Project was a positive psychological intervention designed to address common emotional barriers to physical activity in patients who have recently undergone MBS (e.g., low confidence around exercise, internalized weight bias, fear of injury) and use motivational interviewing and standard behavior change techniques (e.g., self-monitoring) to increase physical activity. This single-arm proof-of-concept trial was designed to refine the intervention, test feasibility and acceptability, and explore pre-post changes in behavioral and psychological outcomes. Participants were 12 adults 6–12 months post-MBS (M age of 46, 58% female, 67% non-Hispanic white). GOALS was a 10-week telephone counseling program that introduced new positive psychological skills and physical activity topics each week. Participants tracked physical activity with a Fitbit and set weekly goals. Results showed that the intervention was feasible (85% of sessions completed) and acceptable (average participant ratings of session ease and utility above 8.0 on a 0–10 scale). There were medium-to-large effect size improvements in physical activity and psychological well-being (e.g., depressive symptoms). The GOALS intervention will next be tested in a pilot randomized controlled trial with longer-term follow-up to assess its effect more robustly.

The Lambda+c lifetime is measured using 9.0 fb(-1) of e+e- annihilation data collected on or just below the Upsilon(4S) resonance with the CLEO II.V detector at CESR. Using an unbinned maximum ...likelihood fit, the Lambda+c lifetime is measured to be 179.6+/-6.9(stat)+/-4.4(syst) fs. The precision of this colliding beam measurement is comparable to other measurements, which are based on fixed-target experiments, with different systematic uncertainties.
Research Objective
Adverse social determinants of health (SDoH) are associated with higher chronic disease prevalence and healthcare utilization. In 2018, Mass General Brigham implemented SDoH ...screening in its Medicaid Accountable Care Organization (ACO) to measure social risk (specific adverse social conditions associated with poor health) and social need (request for assistance). The overlap between patient‐identified social risk and social need is not well understood. The goals of this study were: (1) to compare prevalence of social risk and social need in primary care and (2) to identify patient factors associated with differential prevalence.
Study Design
We conducted a cross‐sectional study of patient responses to a SDoH questionnaire from February 2019 to February 2020. The questionnaire assessed social risk in eight domains (food, housing, medication, transportation, utilities, family care, employment, education) as well as social need by a request for more information in these domains. The questionnaire was available in English or Spanish through a patient portal or on a tablet before routine primary care visits. We applied descriptive statistics to the prevalence of social risk and social need, stratified patient responses by language and race/ethnicity, and compared patient groups using a chi‐squared test.
Population Studied
Adult and pediatric primary care patients in151 practices in the Mass General Brigham Medicaid ACO. Mass General Brigham is a large health system across Massachusetts including both academic medical centers and community physician organizations.
Principal Findings
The study population included 27,500 individuals who completed 30,820 screenings, including 15,219 (55.3%) caregivers of pediatric patients. Of individuals screened, 14.9% were Spanish‐speaking, 32.1% identified as Hispanic or Latino, and 10.2% identified as non‐Hispanic Black or African American. Of completed screenings, 13,736 (44.6%) were positive for 31 social risk and 2954 (9.6%) for33 risks; 5879 (19.1%) were positive for social need and 4863 (35.4%) for both social risk and social need. Notably, 1016 (6.0%) screenings were positive for a social need but negative for social risk. Patients who were Spanish‐speaking, Hispanic, or non‐Hispanic Black reported significantly more social risk and social need, and reported social need while screening negative for social risk significantly more than English‐speaking (9.2% v. 5.4%, p < 0.001) and White patients (8.2% and 8.6% v. 3.8%, p < 0.001) respectively, both overall and in sub‐domains of housing, transportation, utilities, employment, and education.
Conclusions
Almost half of Medicaid ACO patients screened for SDoH reported social risk or social need, with incomplete overlap between these groups. Individuals who identified as Hispanic or non‐Hispanic Black, or who were Spanish‐speaking, had more social risk, social need, and more often reported social needs without reporting risk. Screening for social risk and social need identify different patient populations and screening for both identifies more individuals with adverse SDoH, particularly among historically disadvantaged demographic groups.
Implications for Policy or Practice
Screening for social risk alone is not sufficient to identify all patients with adverse SDoH. We encourage health systems and Medicaid programs to consider screening tools for social risk and patient‐centered questions for social need. Identifying both populations increases the opportunity for intervention and mitigation of negative health effects.
