An Affordable and Sustainable Thrifty-Like Meal Plan, FoodRx, That Meets the Recommended Dietary Allowances.

There is considerable controversy as to whether a healthy diet is affordable given recent inflation. In order to determine whether a healthy, climate-friendly sustainable diet can be obtained within the allotments of the Supplemental Nutrition Assistance Program (SNAP), we created and purchased 26 weeks of meal plans designed to meet the EAT-Lancet sustainability guidelines and > 90% of the RDAs for 23 macro/micronutrients for households with at least 2 adults and 1-3 children. We compared the food quantities and cost of a healthy sustainable diet purchased in Los Angeles, 2023, to the Thrifty Food Plan, 2021. We compared the volume of food and cost of basic groceries to those recommended in the Thrifty Food Plan, 2021. The costs of the sustainable diet fell within the 2023 SNAP allotments as long as the average calories required per person did not exceed 2000. The volume of fruits, vegetables, legumes, nuts, and seeds were considerably higher for the sustainable diet compared to the Thrifty Food Plan. Given that calorie needs are the determinants of food quantity and costs, the USDA may consider offering supplemental coverage for individuals with higher calorie needs to make healthy eating affordable.

History and current status of the survivorship care program at the University of California, Los Angeles Jonsson Comprehensive Cancer Center (UCLA JCCC).

As one of the first comprehensive cancer centers to receive a designation from the National Cancer Institute, the Jonsson Comprehensive Cancer Center at UCLA Health has served as a leader in survivorship research for three decades. A clinical survivorship program for childhood cancer survivors was established in the early 2000s as this became a standard of care in pediatric oncology. However, it was not until receipt of external funding and the establishment of a Survivorship Center of Excellence in 2006 that clinical services were expanded to include adult cancer survivors, as well as survivorship care delivery research in the community and at affiliated clinical sites. When this funding ended, there was limited institutional support for expansion of the program, and so the clinical programs did not develop further. Recently, there has been renewed interest in obtaining Commission on Cancer accreditation, and this has prompted an institutional assessment of survivorship care to inform future activities for system-wide program development. As oncology care expands throughout a large regional health system network, the future survivorship program will need to serve as a common resource for the entire health system by providing a repository of specialized services and resources as well as standard processes and pathways for a cohesive approach to care. IMPLICATIONS FOR CANCER SURVIVORS: There are many challenges to development and sustainment of cancer survivorship programs, even in NCI-designated comprehensive cancers. As the delivery of cancer care services expands and becomes more integrated in large health care systems, innovative strategies are needed to ensure delivery of tailored care to cancer survivors through acute treatment and beyond.

Lessons from Carl M. Pearson 1919 - 1981.

Carl M. Pearson was an energetic and exceptional physician-scholar-leader who founded, established, and broadened the Divisions of Rheumatology at University of California in Los Angeles (UCLA) beginning in 1956. His studies to induce myositis by injecting muscle saturated with the heat-killed tubercle bacillus, an emulsifier, and mineral oil (Freund's adjuvant) enabled his report that polyarthritis occurred with Freund's adjuvant alone in certain strains of rat and mice. This model of adjuvant arthritis allowed the next generation of studies to assess therapies for autoimmune diseases.

Association of neighborhood gentrification and residential moves with hypertension and diabetes control in Los Angeles County, 2014-2019: A retrospective cohort study.

OBJECTIVE: To examine whether gentrification exposure is associated with future hypertension and diabetes control. METHODS: Linking records from an integrated health care system to census-tract characteristics, we identified adults with hypertension and/or diabetes residing in stably low-SES census tracts in 2014 (n = 69,524). We tested associations of census tract gentrification occurring between 2015 and 2019 with participants' disease control in 2019. Secondary analyses considered the role of residential moves (possible displacement), race and ethnicity, and age. RESULTS: Gentrification exposure was associated with improved odds of hypertension control (aOR: 1.08; 95% CI: 1.00, 1.17), especially among non-Hispanic Whites and adults >65 years. Gentrification was not associated with diabetes control overall, but control improved in the Hispanic subgroup. Disease control was similar regardless of residential moves in the overall sample, but disparate associations emerged in models stratified by race and ethnicity. CONCLUSIONS: Residents of newly gentrifying neighborhoods may experience modestly improved odds of hypertension and/or diabetes control, but associations may differ across population subgroups. POLICY IMPLICATIONS: Gentrification may support-or at least not harm-cardiometabolic health for some residents. City leaders and health systems could partner with impacted communities to ensure that neighborhood development meets the goals and health needs of all residents and does not exacerbate health disparities.

Opium, phencyclidine, and crack cocaine smoking associations with lung and upper aerodigestive tract cancers: exploratory findings from a case-control study in Los Angeles County.

Background: Illicit drug use has become a global epidemic, yet it is unclear if drug smoking increases the risk of tobacco-related cancers.Objectives: We aimed to evaluate hypothesized associations between smoking three drugs - opium, phencyclidine (PCP) and crack cocaine and lung and upper aerodigestive tract (UADT) cancers.Methods: A population-based case-control study with 611 lung cancer cases (50% male), 601 UADT cancers cases (76% male), and 1,040 controls (60% male) was conducted in Los Angeles County (1999-2004). Epidemiologic data including drug smoking histories were collected in face-to-face interviews. Associations were estimated with logistic regressions.Results: Adjusting for potential confounders, ever vs. never crack smoking was positively associated with UADT cancers (aOR = 1.56, 95% CI: 1.05, 2.33), and a dose-response relationship was observed for lifetime smoking frequency (p for trend = .024). Heavy (> median) vs. never crack smoking was associated with UADT cancers (aOR = 1.81, 95% CI: 1.07, 3.08) and lung cancer (aOR = 1.58, 95% CI: 0.88, 2.83). A positive association was also observed between heavy PCP smoking and UADT cancers (aOR = 2.29, 95% CI: 0.91, 5.79). Little or no associations were found between opium smoking and lung cancer or UADT cancers.Conclusion: The positive associations between illicit drug use and lung and/or UADT cancers suggest that smoking these drugs may increase the risk of tobacco-related cancers. Despite the low frequency of drug smoking and possible residual confounding, our findings may provide additional insights on the development of lung and UADT cancers.

The COVID-19 infection control response at a large stand-alone comprehensive cancer center in Los Angeles County.

BACKGROUND: The City of Hope National Medical Center (COH) is the only stand-alone comprehensive cancer center in Los Angeles, a county that was deemed a COVID-19 pandemic epicenter at the height of the 2020 winter surge. The immunocompromised patient population frequently experienced delays in infection control guidelines from local and government bodies due to minimal data available in comparison to the general population. This required COH to make swift, informed decisions for the best interest of the patient population. AIM: Here, we review the comprehensive COVID-19 infection control response conducted at COH within the context of a high-risk patient population, predominately comprised of patients with hematologic malignancies. METHODS AND RESULTS: This infection control response focused on prevention of COVID-19 transmission on campus, COVID-19 testing, and isolation management. These efforts consisted of COVID-19 screening, limitation of personnel on campus, source control, contact tracing, COVID-19 vaccination, establishment of in-house testing and implementation and management of COVID-19 testing. Between January 2020 and September 2021, COH implemented a robust in-house testing program, completed well over 1000 contact traces, ensured COVID-19 vaccinations were distributed to all eligible staff and patients, and established an algorithm for COVID-19 infection resolution, all without compromising the number of hematopoietic stem cell transplants (HCTs) performed, surgical volume, or healthcare-associated standardized infection ratios (SIR). CONCLUSION: Institutional collaboration and attention to infection control was pivotal to minimizing the burden of the COVID-19 pandemic.

The Role of Neighborhood Air Pollution Exposure on Somatic Non-Small Cell Lung Cancer Mutations in the Los Angeles Basin (2013-2018).

Limited previous work has identified a relationship between exposure to ambient air pollution and aggressive somatic lung tumor mutations. More work is needed to confirm this relationship, especially using spatially resolved air pollution. We aimed to quantify the association between different air pollution metrics and aggressive tumor biology. Among patients treated at City of Hope Comprehensive Cancer Center in Duarte, CA (2013-2018), three non-small cell lung cancer somatic tumor mutations, TP53, KRAS, and KRAS G12C/V, were documented. PM2.5 exposure was assessed using state-of-the art ensemble models five and ten years before lung cancer diagnosis. We also explored the role of NO2 using inverse-distance-weighting approaches. We fitted logistic regression models to estimate odds ratio (OR) and their 95% confidence intervals (CIs). Among 435 participants (median age: 67, female: 51%), an IQR increase in NO2 exposure (3.5 µg/m3) five years before cancer diagnosis was associated with an increased risk in TP53 mutation (OR, 95% CI: 1.30, 0.99-1.71). We found an association between highly-exposed participants to PM2.5 (>12 µg/m3) five and ten years before cancer diagnosis and TP53 mutation (OR, 95% CI: 1.61, 0.95-2.73; 1.57, 0.93-2.64, respectively). Future studies are needed to confirm this association and better understand how air pollution impacts somatic profiles and the molecular mechanisms through which they operate.

Evaluating Real World Mutational Differences Between Hispanics and Asians in NSCLC at a Large Academic Institution in Los Angeles.

INTRODUCTION: Hispanics living in the United States have higher rates of Epidermal Growth Factor Receptor (EGFR) mutations compared with Non-Hispanic Whites. While this higher incidence is like Asian patients living in the United States, the outcomes for Hispanic patients differ. We looked to compare the variances in mutational profiles between Hispanics and Asians in Los Angeles. PATIENTS AND METHODS: Three hundred ninety three non-small cell lung cancer (NSCLC) patients treated at Los Angeles County + University of Southern California (LAC + USC) Medical Center and Norris Comprehensive Cancer Center who received comprehensive genomic profiling (CGP) were evaluated from July 2017 to August 2020. CGP was done using tissue biopsies (n = 211) from Caris Life Sciences and liquid biopsies (n = 231) from Guardant Health. Multivariate logistic regression evaluated the role of race between Hispanics and Asians. RESULTS: In the Hispanic cohort (n = 90), 50.0% were male, median age of diagnosis was 62, 54.5% were non-smokers, and 85.5% had adenocarcinoma. In Asians (n = 142), 47.5% were male, median age of diagnosis was 65, 59.6% were non-smokers, and 83.8% had adenocarcinoma. Hispanic patients had greater prevalence of Kirsten rat sarcoma virus (KRAS) mutations (odds ratio [OR] 4.42, 95% confidence interval [95% CI]: 1.63-12.83) and lesser prevalence of EGFR mutations (OR 0.31, 95% CI: 0.16-0.59). There were a greater proportion of Hispanic smokers with KRAS mutations (14/41; 34.1%) than Asian smokers (4/58; 6.9%). CONCLUSION: We saw a greater percentage of Hispanics with KRAS mutations despite similar smoking percentages along with a greater percentage of Asians with EGFR mutations. This study shows that ethnic and racial backgrounds of the patient can influence the effects of potentially carcinogenic exposures leading to variances of mutation frequency of NSCLC among different ethnicities.

Electrophysiological Characteristics of Intra-Atrial Reentrant Tachycardia in Adult Congenital Heart Disease: Implications for Catheter Ablation.

Background Ultra-high-density mapping enables detailed mechanistic analysis of atrial reentrant tachycardia but has yet to be used to assess circuit conduction velocity (CV) patterns in adults with congenital heart disease. Methods and Results Circuit pathways and central isthmus CVs were calculated from consecutive ultra-high-density isochronal maps at 2 tertiary centers over a 3-year period. Circuits using anatomic versus surgical obstacles were considered separately and pathway length <50th percentile identified small circuits. CV analysis was used to derive a novel index for prediction of postablation conduction block. A total of 136 supraventricular tachycardias were studied (60% intra-atrial reentrant, 14% multiple loop). Circuits with anatomic versus surgical obstacles featured longer pathway length (119 mm; interquartile range [IQR], 80-150 versus 78 mm; IQR, 63-95; P<0.001), faster central isthmus CV (0.1 m/s; IQR, 0.06-0.25 versus 0.07 m/s; IQR, 0.05-0.10; P=0.016), faster non-isthmus CV (0.52 m/s; IQR, 0.33-0.71 versus 0.38 m/s; IQR, 0.27-0.46; P=0.009), and fewer slow isochrones (4; IQR, 2.3-6.8 versus 6; IQR 5-7; P=0.008). Both central isthmus (R2=0.45; P<0.001) and non-isthmus CV (R2=0.71; P<0.001) correlated with pathway length, whereas central isthmus CV <0.15 m/s was ubiquitous for small circuits. Non-isthmus CV in tachycardia correlated with CV during block validation (R2=0.94; P<0.001) and a validation map to tachycardia conduction time ratio >85% predicted isthmus block in all cases. Over >1 year of follow-up, arrhythmia-free survival was better for homogeneous CV patterns (90% versus 57%; P=0.04). Conclusions Ultra-high-density mapping-guided CV analysis distinguishes atrial reentrant patterns in adults with congenital heart disease with surgical obstacles producing slower and smaller circuits. Very slow central isthmus CV may be essential for atrial tachycardia maintenance in small circuits, and non-isthmus conduction time in tachycardia appears to be useful for rapid assessment of postablation conduction block.

Community-based organizations' perspectives on improving health and social service integration.

BACKGROUND: Collaborations between health systems and community-based organizations (CBOs) are increasingly common mechanisms to address the unmet health-related social needs of high-risk populations. However, there is limited evidence on how to develop, manage, and sustain these partnerships, and implementation rarely incorporates perspectives of community social service organizations. To address these gaps, we elicited CBOs' perspectives on service delivery for clients, the impact of the Whole Person Care-Los Angeles (WPC-LA) initiative to integrate health and social care, and their suggestions for improving health system partnerships. METHODS: Using stakeholder engaged principles and a qualitative Rapid Assessment Process, we conducted brief surveys and in-depth semi-structured interviews with 65 key informants from 36 CBOs working with WPC-LA. RESULTS: Major themes identified by CBOs included: 1) the importance of a holistic, client-centered, continuously engaged approach that is reliant on regional partnerships; 2) benefits of WPC-LA expanding capacity and networks; 3) concerns about communication and redundancy hindering WPC-LA; and 4) a need for more equitable partnerships incorporating their approaches. CONCLUSIONS: CBOs value opportunities for integration with health systems, bring critical expertise to these partnerships, and seek to strengthen cross-sector collaborations. Early, equitable, and inclusive participation in the development and implementation of these partnerships may enhance their effectiveness, but requires policy that prioritizes and incentivizes sustainable and mutually beneficial partnerships.

Comparison of Fruit and Vegetable Intake Among Urban Low-Income US Adults Receiving a Produce Voucher in 2 Cities.

Importance: Fruit and vegetable vouchers have been implemented by cities and counties across the US to increase fruit and vegetable intake and thereby improve overall nutritional quality. Objective: To determine whether and why use of fruit and vegetable vouchers are associated with varied nutritional intake across different populations and environments. Design, Setting, and Participants: In a population-based pre-post cohort study of 671 adult participants with low income before and during (6 months after initiation) participation in a 6-month program, fruit and vegetable vouchers were distributed for redemption at local San Francisco and Los Angeles neighborhood grocery and corner stores between 2017 and 2019. A transportability analysis was performed to identify factors that may explain variation in voucher use between cities. Exposure: Receipt of $20 per month in produce vouchers for 6 months from 2017 to 2019. Main Outcomes and Measures: Change in total fruits and vegetables (as defined by the US Department of Agriculture) consumed per person per day (change in cup-equivalents between month 6 and month 0). Results: A total of 671 adults (median age, 54.9 years [interquartile range, 45.0-65.0 years]; 61.7% female; 30.9% Black; 19.7% Hispanic) were enrolled. An increase in fruit and vegetable intake of 0.22 cup-equivalents per day overall (95% CI, 0.14-0.31 cup-equivalents; P < .001) was observed. However, the observed increase was larger in Los Angeles compared with San Francisco (0.64 cup-equivalents per day; 95% CI, 0.41-0.88 cup-equivalents vs 0.10 cup-equivalents per day; 95% CI, 0.01-0.19 cup-equivalents). When the concurrently sampled San Francisco group (n = 157) was weighted in transportability analysis to demographically match the Los Angeles group (n = 155) in observed covariates, the weighted San Francisco group had an estimated increase of 0.53 fruit and vegetable cup-equivalents per day (95% CI, 0.27- 0.79 cup-equivalents, P = .03), with income being the variable needed to allow the 95% confidence intervals to overlap between the weighted San Francisco and unweighted Los Angeles populations. Conclusions and Relevance: In this study, the use of fruit and vegetable vouchers appeared to be associated with greater benefit among those with lower incomes, suggesting that further investigation of flat-rate rather than income-scaled benefits is warranted.

Initial Efficacy of a Community-Derived Mindfulness-Based Intervention for Latinx Parents and their Children.

Mindfulness-based interventions (MBIs) may offer a means for Latinx families to ameliorate stress, enhance emotion regulation, and foster social support. We assessed pilot data from Latinx parents in Eastside Los Angeles (n = 27) matched with their children aged 10-16 (n = 32) to determine whether participation in a community-derived MBI was associated with greater improvements in dispositional mindfulness, perceived stress, emotion regulation, and family social support compared to a control condition. Compared to the control group, parents in the MBI group showed greater reductions in perceived stress scale (PSS) scores (B = - 2.94, 95% CI [- 5.58, - 0.39], p = 0.029), while their children reported greater increases in perceived social support from family (B = 2.32, 95% CI [0.26, 4.38], p = 0.027). Findings show a community-derived MBI may improve stress in Latinx parents and social support for their children.

Can Outpatient Plastic Surgery Be Done Safely During a COVID-19 Surge? Results of a July 2020 Los Angeles Survey and Literature Review.

BACKGROUND: A moratorium was placed on nonurgent surgery throughout much of the United States in mid-March 2020 due to surging numbers of COVID-19 cases. Several months later, and with new safety precautions in place, elective surgery gradually resumed. However, no data exist on the safety of plastic surgery during the pandemic. OBJECTIVES: This aim of this survey was to assess the safety of plastic surgery during the pandemic by quantifying: (1) the preoperative prevalence of SARS-CoV-2; (2) the risk of postoperative COVID-19; (3) outcomes and precious resource utilization for such cases; and (4) the risks to office staff. METHODS: Los Angeles plastic surgeons certified by the American Board of Plastic Surgery (ABPS) were sent an online survey in July 2020, during a local COVID-19 surge, querying about the number of procedures performed in the 8- to 10-week period since reopening, testing policies, surgical complications, and cases among staff. RESULTS: In total, 112 surgeons reported 5633 surgeries since resuming elective surgery. Of these, 103 (91.96%) surgeons obtained a preoperative SARS-CoV-2 polymerase chain reaction (PCR) test for every patient. The preoperative PCR test was positive in 41/5881 (0.69%). Positive tests within 2 weeks postoperation occurred in 7/5380 (0.13%) of surgical patients, 3/8506 (0.04%) of injection patients, and 6/2519 (0.24%) of energy therapy patients. Nine offices reported at least 1 staff member who developed COVID-19. All cases were mild, with no hospitalizations or deaths. CONCLUSIONS: These data demonstrate that plastic surgery can be performed safely during a COVID-19 surge by ABPS diplomates. This has profound impact for patients, plastic surgeons, and health policy regulators.

The Leveraging Exercise to Age in Place (LEAP) Study: Engaging Older Adults in Community-Based Exercise Classes to Impact Loneliness and Social Isolation.

OBJECTIVE: Social isolation and loneliness are associated with morbidity and mortality in older adults. Limited evidence exists regarding which interventions improve connectedness in this population. DESIGN/SETTING/PARTICIPANTS: In this pre-post study we assessed community-based group health class participants' (age ≥50) loneliness and social isolation. Participants (n = 382) were referred by a Cedars-Sinai Medical Network (Los Angeles, California) healthcare provider or self-referred from the community (July 2017-March 2020). INTERVENTION: Participants met with a program coordinator and selected Arthritis Exercise, Tai Chi for Arthritis, EnhanceFitness, or the Healthier Living Workshop. MEASUREMENTS: We measured social isolation using the Duke Social Support Index (DSSI) and loneliness using the UCLA 3-item Loneliness Scale at baseline, class completion, and 6 months. RESULTS: Mean age was 76.8 years (standard deviation, SD = 9.1); 315 (83.1%) were female; 173 (45.9%) were Non-Hispanic white; 143 (37.9%) were Non-Hispanic Black; 173 (46.1%) lived alone; mean baseline DSSI score was 26.9 (SD = 4.0) and mean baseline UCLA score was 4.8 (SD = 1.8). On multivariable analysis adjusted for gender, race/ethnicity, income, self-rated health, and household size, DSSI improved by 2.4% at 6-week compared to baseline (estimated ratio, ER: 1.024; 95% confidence interval [CI]: 1.010-1.038; p-value = 0.001), and 3.3% at 6-month (ER: 1.033; 95% CI: 1.016-1.050; p-value <0.001). UCLA score after adjusting for age, gender, race/ethnicity, live alone, number of chronic conditions, income, and self-rated health, did not change at 6-week (ER: 0.994; 95% CI: 0.962-1.027; p-value = 0.713), but decreased by 6.9% at 6-months (ER: 0.931; 95% CI: 0.895-0.968; p-value <0.001). CONCLUSION: Community-based group health class participants reported decreased loneliness and social isolation at 6-month follow-up.

The role of income and neighbourhood poverty in the association between the 2009 Special Supplemental Nutrition Program for Women, Infants and Children (WIC) food package change and child obesity among WIC-participating children in Los Angeles County, 2003-2016.

OBJECTIVE: To determine whether a previously reported association between the Special Supplemental Nutrition Program for Women, Infants and Children (WIC) food package change and reduced child obesity risk among WIC-participating children in Los Angeles County holds across levels of family income and neighbourhood poverty. DESIGN: Analysis of prospectively collected WIC administrative data. The outcome was obesity at age 4 years (BMI-for-age ≥ 95th percentile). Poisson regression was applied to a matched sample (n 79 502) to determine if the association between the WIC food package change and child obesity was modified by family income (<50 % federal poverty level (FPL), 50-100 % FPL, >100 % but <185 % FPL) and neighbourhood poverty. SETTING: Los Angeles County, California. PARTICIPANTS: Children who participated in WIC in Los Angeles County between 2003 and 2016; children were grouped as receiving the old WIC food package (2003-2009) or the new WIC food package (2010-2016). RESULTS: Receiving the new WIC food package (i.e., post-2009) was associated with 7-18 % lower obesity risk across all family income categories. Neither family income nor neighbourhood poverty significantly modified the association between the WIC food package and child obesity. However, certain sub-groups seemed to benefit more from the food package change than others. In particular, boys from families with income above poverty but residing in the poorest neighbourhoods experienced the greatest reductions in obesity risk (relative risk = 0·77; 95 % CI 0·66, 0·88). CONCLUSIONS: The WIC food package revisions were associated with reduced childhood obesity risk among all WIC-participating families in Los Angeles County, across levels of income eligibility and neighbourhood poverty.

Cognitive Factors Associated with Frequency of Eating Out and Eating Takeout among Latinas.

Higher frequency of eating outside the home can be an unhealthy behavior that may contribute to higher rates of obesity among Latinas, a disproportionately affected group. There is a growing need to understand potentially modifiable factors (eg, dispositional mindfulness, self-efficacy, nutrition knowledge) associated with higher frequency of eating outside the home in this population. This study assessed associations of cognitive factors (ie, dispositional mindfulness, self-efficacy of eating and purchasing healthy foods, nutrition knowledge) with frequency of eating out among Latinas. A secondary analysis was performed of data from a cross-sectional study of Latinas between February and May 2015. The study comprised a convenience sample of 218 Spanish- or English-literate Latinas, between the ages of 18 and 55 years, who lived in South or East Los Angeles and self-identified as the primary person responsible for grocery shopping in the household. Most participants identified as foreign-born Mexican Americans. Frequency of eating out was assessed as the outcome variable, and three cognitive variables (mindfulness disposition, self-efficacy, nutrition knowledge) served as independent variables. Multinomial models assessed the association between cognitive factors and frequency of eating out. Models were adjusted for age, English-speaking ability, income, having an obesity-related disease (ie, overweight or obesity, diabetes, high blood pressure, cardiovascular disease), household size, and education level. For every 1-unit increase in mindfulness disposition, the risk of a participant eating out every week compared with every month decreased by a factor of 0.42 (relative risk ratio [RRR] = 0.58, P < 0.01). For every 1-unit increase in self-efficacy, the risk of a participant eating out every week compared with every month decreased by a factor of 0.32 (RRR = 0.68, P < 0.05), and the risk of a participant eating out every 2 weeks compared with every month decreased by a factor of 0.44 (RRR = 0.56, P < 0.05). For every 1-unit increase in nutrition knowledge, the risk of a participant eating out every week compared with every month increased by a factor of 1.42 (RRR = 1.42, P < 0.01). Lower dispositional mindfulness was associated with higher frequency of eating out when comparing individuals who ate out at least every week with those who ate out once a month or less or every 2 weeks. Lower self-efficacy was associated with eating out more when comparing those who ate out once a month or less with those who ate out at least every week or every 2 weeks. Lower nutrition knowledge was associated with lower frequency of eating out for participants who ate out once a month or less compared with those who ate out at least every week.

The Effect of Early Treatment with Intravenous Magnesium Sulfate on the Incidence of Cardiac Comorbidities in Hospitalized Stroke Patients.

BACKGROUND: Cardiac adverse events are common among patients presenting with acute stroke and contribute to overall morbidity and mortality. Prophylactic measures for the reduction of cardiac adverse events in hospitalized stroke patients have not been well understood. We sought to investigate the effect of early initiation of high-dose intravenous magnesium sulfate on cardiac adverse events in stroke patients. METHODS: This is a secondary analysis of the prehospital Field Administration of Stroke Therapy-Magnesium (FAST-MAG) randomized phase-3 clinical trial, conducted from 2005-2013. Consecutive patients with suspected acute stroke and a serum magnesium level within 72 hours of enrollment were selected. Twenty grams of magnesium sulfate or placebo was administered in the ambulance starting with a 15-minute loading dose intravenous infusion followed by a 24-hour maintenance infusion in the hospital. RESULTS: Among 1126 patients included in the analysis of this study, 809 (71.8%) patients had ischemic stroke, 277 (24.6%) had hemorrhagic stroke, and 39 (3.5%) with stroke mimics. The mean age was 69.5 (SD13.4) and 42% were female. 565 (50.2%) received magnesium treatment, and 561 (49.8%) received placebo. 254 (22.6%) patients achieved the target, and 872 (77.4%) did not achieve the target, regardless of their treatment group. Among 1126 patients, 159 (14.1%) had at least one CAE. Treatment with magnesium was not associated with fewer cardiac adverse events. A multivariate binary logistic regression for predictors of CAEs showed a positive association of older age and frequency of CAEs (R = 1.04, 95% CI 1.03-1.06, p < 0.0001). Measures of early and 90-day outcomes did not differ significantly between the magnesium and placebo groups among patients who had CAEs. CONCLUSION: Treatment of acute stroke patients with magnesium did not result in a reduction in the number or severity of cardiac serious adverse events.

Novel Use of Rapid Antigen Influenza Testing in the Outpatient Setting To Provide an Early Warning Sign of Influenza Activity in the Emergency Departments of an Integrated Health System.

Seasonal influenza virus is associated with high morbidity and mortality especially in vulnerable patient populations. Here, we demonstrate the novel use of Sofia influenza A+B fluorescent immunoassay (FIA), a rapid antigen-based influenza point-of-care test (POCT), combined with Virena software for automatic deidentified tracking of influenza activity across the Los Angeles area and for predicting surges of influenza cases in the emergency department (ED). We divided outpatient clinics into 6 geographic zones and compared weekly influenza activity. In the outpatient setting, there were 1,666 and 274 influenza A and influenza B positives, respectively, across the 2018 to 2019 influenza season and 1,857 and 1,449 influenza A and influenza B positives, respectively, during the 2019 to 2020 influenza season, with zone-specific differences observed. Moreover, we found that a rapid increase in outpatient influenza was followed by an influx in influenza-positive cases in the ED, offering a 1- to 3-week warning sign for ED influx of triple or quadruple the number of influenza cases compared to the prior week. Sofia influenza A+B FIA allows for surveillance of real-time deidentified influenza activity. Tracking of such data may serve as a valuable region-specific influenza indicator and predictor to guide infection prevention measures in both the outpatient and hospital settings. High-impact interventions include designating areas for waiting rooms for influenza-like illnesses, altering staff scheduling in anticipation of surges, and securing sufficient personal protective equipment and antivirals during the height of influenza season.

Investigating possible syndemic relationships between structural and drug use factors, sexual HIV transmission and viral load among men of colour who have sex with men in Los Angeles County.

INTRODUCTION AND AIMS: Past research investigating syndemic factors and HIV-related outcomes has overlooked the impact of structural conditions on behaviours linked with HIV transmission and disease progression. Given prevalent substance use among our sample, we explored whether four structural conditions indicative of social marginalisation and previously correlated with increased risk for HIV infection demonstrated syndemic (additive/synergistic) effects on: (i) HIV viral suppression; and (ii) self-reported involvement in sexual HIV transmission behaviours among a prospective cohort mostly comprising men of colour who have sex with men (MCSM; i.e. Latino/Hispanic and African American/black men) in Los Angeles County. DESIGN AND METHODS: Data were collected between August 2014 and March 2017. The structural conditions of interest were: current unemployment, recent (≤6 months) incarceration history, 'unstable' accommodation (past month) and remote (>6 months) contact with health-care providers. Generalised estimating equations assessed possible additive effects of experiencing multiple structural conditions, and possible synergistic effects on the HIV-related outcomes. RESULTS: Of 428 participants, nearly half (49%) were HIV-positive at baseline. Involvement in sexual HIV transmission risk behaviours varied over follow-up (22-30%). Reporting ≥2 structural syndemic conditions was significantly associated with reporting sexual HIV transmission risk behaviours among HIV-negative participants, and detectable viral load among HIV-positive participants. Frequent methamphetamine use was consistently associated with the HIV-related outcomes across the final multivariate models. DISCUSSION AND CONCLUSIONS: When developing initiatives to address HIV transmission among marginalised sub-populations including MCSM, we must holistically consider systemic and structural issues (e.g. unemployment and homelessness), especially in the context of prevalent substance use.

Barriers to Health Care for Latino Youths During Community Reentry After Incarceration: Los Angeles County, California, 2016-2018.

Objectives. To examine barriers to health care for Latino youths during reentry after incarceration.Methods. For this in-depth qualitative study, we conducted 69 semistructured interviews with 22 Latino youths and their parents at 1, 3, and 6 months after incarceration. We performed thematic analysis of interview transcripts, from which a preliminary conceptual model emerged describing barriers to care for Latino youths. We then conducted trajectory analyses of dyadic youth-caregiver pairs to test the conceptual model. We collected longitudinal interviews in Los Angeles County, California, from November 2016 to March 2018.Results. Beyond recognized stressors experienced by youths during reentry, most of which families related to poverty and neighborhood environment, Latino youths also experienced cultural barriers to care (i.e., self-reliance and pride, religiosity and reproductive care as taboo, preference for home remedies, language) as well as barriers to care because of undocumented status (i.e., fear of deportation, job insecurity).Conclusions. Reentry is challenging, and Latino youths face additional barriers to care during reentry related to culture and legal status, but have cultural strengths. Increased access to culturally sensitive, safety-net health care, regardless of immigration status, may reduce health inequalities for Latino youths undergoing reentry.
