Discovering the Roots: A Qualitative Analysis of Medical Students Exploring Their Unconscious Obesity Bias.

Phenomenon: Bias against individuals with obesity in medical settings has negative implications for patients, including stigmatization, poor health outcomes, and reduced healthcare utilization. This study explored reflections of medical students when confronted with their own implicit obesity bias.Approach: A group of 188 pre-clinical second-year medical students from George Washington University School of Medicine and Health Sciences completed the Weight Implicit Association Test (IAT) in 2020 and were instructed to write a reflective response based on their results. Participants reflected upon their preferences ("fat" vs. "thin") and described the factors that influenced their perceptions of obesity. Inductive coding techniques were used to generate themes from medical students' responses using Dedoose Version 8.3.35 (SocioCultural Research Consultants LLC, Los Angeles, California).Findings: Regarding IAT results, 7% of medical students preferred "fat over thin," 14% had no preference, and 78% preferred "thin over fat." Reflection themes highlighted medical students' difficulty accepting IAT results, perspectives on the origins of obesity in individuals, personal and family challenges with obesity and body image, medical training's perceived influence on bias, reservations about discussing obesity with patients, and desires to change current and future practices.Insights: Many medical students expressed a desire to provide optimal care for patients of all weight classes despite demonstrating a strong unconscious bias against individuals with obesity on the IAT. Medical school should provide targeted opportunities to acknowledge and mitigate obesity bias by expanding on medical students' pre-established and often harmful understandings of obesity and highlighting the complexities of this disease. Such training would better equip medical students to facilitate successful interactions with patients as future physicians.

School absenteeism and impairment associated with weight bullying.

INTRODUCTION: Many children experience weight-based bullying (WB), when individuals are treated poorly or demeaned because of weight. WB has negative mental and physical health consequences. The current study examined how children's experiences of different forms of WB (verbal, social, physical, cyber) were associated with impaired functioning in school, social life, and family life. METHODS: Data were collected in Spring 2021. Participants (N = 224) were parents of a school-aged child and lived in the United States. Sixty percent of parents were mothers and 72% of parents self-identified as White. They completed surveys regarding weight, eating, and bullying. RESULTS: Social and cyber WB were associated with clinically significant impairment for both children and parents. Children who experienced social and physical WB were more likely to skip school, whereas physical and cyber WB were associated with skipping a particular class. All forms of bullying were associated with skipping gym class. Social and cyber WB were associated with isolating. Cyber WB was associated with all disordered eating behaviors. In addition, physical WB was associated with binge eating, social WB was associated with purging, and verbal WB was associated with secretive eating. DISCUSSION: Victims of WB experience impairment in school, social life, and family life, absenteeism, and disordered eating. It is essential to develop approaches to address WB in its various forms to identify strategies for reducing and preventing WB across various levels of influence, including peer groups, schools, and families.

Engaging Faith-Based Organizations to Promote Health Through Health Ministries in Washington, DC.

This article describes capacity building and formative assessments completed at five faith-based organizations (FBOs) in Washington, DC to inform sustainable health promotion programming led by certified health ministers. Five FBO partners were recruited with two congregation members from each FBO completing a health minister certificate program. A series of health assessments were conducted to assess each FBO's capacity to implement evidence-based lifestyle change programs that are responsive to congregation members' health needs. Results indicated a need for programming to support older adults in managing high blood pressure and arthritis. Health ministers represent a significant opportunity for building capacity within FBOs to deliver programming that can improve health outcomes.

Distinctiveness and significance of body dissatisfaction and overvaluation among Latinx/Hispanic and White men and women.

OBJECTIVE: To examine the distinctiveness and significance of two body image constructs, dissatisfaction with weight and shape and overvaluation of weight and shape, with respect to eating disorder psychopathology, weight, and depression in White and Latinx/Hispanic men and women. METHODS: Participants were White (n = 1,941) and Latinx/Hispanic (n = 568) adults living in the United States who completed an online battery of established measures of body image, eating disorder psychopathology and behaviors, and depression. RESULTS: Two body image constructs, dissatisfaction with weight and shape and overvaluation of weight and shape, were related to each other but showed some important distinctions in their associations with eating- and weight-related variables. Significantly greater proportions of White than Latinx/Hispanic individuals reported co-occurring dissatisfaction and overvaluation, and significantly greater proportions of Latinx/Hispanic than White individuals reported dissatisfaction alone. Ethnicity moderated the association of dissatisfaction and overvaluation with body mass index (BMI), and the association of overvaluation with depression. Ethnicity also had a main effect on binge-eating frequency. CONCLUSIONS: Dissatisfaction and overvaluation were distinct among both Latinx/Hispanic and White individuals. However, associations with eating- and weight-related variables varied between ethnicities, suggesting a need for further research on the influence of cultural variables on body image and eating disorder psychopathology.

Interest in Receiving Nutrition Information Through Social Media Among Food-Security Program Participants in Washington, DC.

INTRODUCTION: Effective communication approaches are necessary to reach food-security program participants. Accessing food-security programs has been especially challenging during the COVID-19 pandemic. Social media can play an important role in reducing some communication barriers. We examined interest in receiving nutrition information via social media among adults participating in food-security programs in Washington, DC. METHODS: We developed and administered a 22-item survey to adults participating in food-security programs (N = 375). Participants were recruited at Martha's Table, in Washington, DC, from January through March 2020. We performed bivariate analyses and multinomial logistic regressions to examine predictors of interest in receiving nutrition information via social media. RESULTS: Sixty-nine percent of participants reported using social media, and 49% expressed interest in receiving nutrition information via social media. Higher levels of self-efficacy and belief in the value of digital technology were associated with greater likelihood of interest in receiving nutrition information via social media (χ2 6 = 139.0; Nagelkerke R2 = 0.35; P < .001). We found no differences by sex or digital technology access in interest in receiving nutrition information via social media. CONCLUSION: Social media is a widely used and a feasible method to reach food-security program participants. Understanding program participants' interest in receiving health information via social media may help food-security programs plan effective communication strategies to improve food security, especially when in-person participation is limited, such as during the COVID-19 pandemic.

Review and Update: Hematologic Malignancies and Adult Cardiac Surgery.

As treatments for hematologic malignancies continue to advance, many patients with active disease and many more in remission will present for cardiac surgical procedures. Radiation and chemotherapeutic therapies for hematologic malignancies often result in cardiopulmonary injury. Evidence demonstrates that patients with hematologic malignancies undergoing cardiac surgery are at risk for perioperative adverse events, including bleeding, clotting, infection, and immunomodulation. However, short- and long-term mortality has been found to be acceptable. This review will distinguish the important points of characterizing, understanding, and managing hematologic malignancies in the cardiac surgical patient.

Trends and Outcomes of Mechanical Circulatory Support in Peripartum Women, 2002-2014: A Nationwide Inpatient Sample Analysis.

OBJECTIVES: To systematically explore the relationship among the use of mechanical circulatory support (MCS), the timing of placement, and outcomes in pregnancy. DESIGN: Using the National Inpatient Sample and National Readmissions Database, the authors performed a retrospective, cohort analysis of peripartum women who received MCS. SETTING: United States hospitals. PARTICIPANTS: A weighted sample of women who received MCS during the antepartum, delivery, or postpartum period between 2002 and 2014. INTERVENTIONS: MCS MEASUREMENTS AND MAIN RESULTS: There were 1,386 women who received MCS during their admission. These women were older and had more comorbidities than women without MCS. The mean time from admission to device placement was 5.4 days for all women, and MCS use was highest in urban teaching hospitals. Overall, peripartum use of MCS has increased since 2002, but mortality did not change during the same period. After adjusting for potential confounders, the odds ratio for mortality when MCS was placed within 6 days of admission was 0.48 (95% confidence interval 0.23-0.98) with the adjusted probability of death rising from 18.6% to 32.5% when the device was placed on or after day 6. CONCLUSIONS: Similar to trends in the general population, use of MCS has increased in the peripartum period. Women receiving MCS were generally older and had more comorbidities than those not receiving MCS. Increased time to device placement may worsen mortality. Further research will help identify appropriate candidates and factors that improve survival.

Characteristics Associated With Mortality in 372 Patients Receiving Low-Dose Recombinant Factor VIIa (rFVIIa) for Cardiac Surgical Bleeding.

OBJECTIVE: Activated recombinant factor VII (rFVIIa) has been used to treat cardiac surgical bleeding in an off-label manner. This observational report analyzes the outcomes with use of a low dose and early administration of rFVIIa for cardiac surgical bleeding. DESIGN: A retrospective, observational study. SETTING: Single-center, tertiary care cardiothoracic surgical setting. PARTICIPANTS: A total of 6,862 patients underwent cardiac surgery from January 2012 to January 2018. Of those, 372 patients received rFVIIa perioperatively. INTERVENTIONS: An institutional policy directed low-dose, incremental aliquots of intravenous rFVIIa (0.5-1 mg). Characteristics and outcomes were compared among patients who survived (n = 328) and patients who died (n = 44). MEASUREMENTS AND MAIN RESULTS: The median dose of rFVIIa was low at 13.29 µg/kg. Higher doses were given to patients who died (15.79 µg/kg v 12.99 µg/kg; p = 0.0133). Patients who died received more blood and component transfusions (median 9 products in those who died v 6 products in survivors; p = 0.0022), although the median transfusion requirement for all patients was 6 units per patient. The rate of reoperation was not different in the 2 groups. Mortality was associated with emergent/urgent surgical procedures (p = 0.0282), type of surgical procedure with aortic procedures being highest risk (p = 0.0014), cardiogenic shock (p = 0.0028), postoperative renal failure (p = 0.0035), postoperative cardiac arrest (p = 0.0006), and ischemic stroke (p = 0.0084). CONCLUSION: Mortality after life-threatening cardiac surgical bleeding treated with rFVIIa was more common in aortic procedures and emergent and urgent surgeries. Lower doses of rFVIIa than previously reported may achieve bleeding cessation because overall blood component transfusions were low in this cohort.

Intraoperative Use of Nondepolarizing Neuromuscular Blocking Agents During Cardiac Surgery and Postoperative Pulmonary Complications: A Prospective Randomized Trial.

OBJECTIVE: Nondepolarizing neuromuscular blocking agents (NMBAs) are associated with perioperative complications in noncardiac surgery; however, little is known about their effect on cardiac surgery. This study assessed the effect of neuromuscular blockade (NMB) on the incidence of postoperative pulmonary complications (PPCs) after cardiac surgery and operating conditions. DESIGN: Prospective, randomized clinical trial with blinded outcomes assessment. SETTING: University hospital, single institution. PARTICIPANTS: Adult patients having cardiac surgery requiring cardiopulmonary bypass. INTERVENTIONS: One hundred patients were randomized to receive succinylcholine (group SUX) for intubation with no further NMB administered or cisatracurium (group CIS) for intubation and maintenance NMB. The primary outcome was a composite incidence of PPCs in the 72 hours after elective cardiac surgery. PPCs included failure to extubate within 24 hours, need for reintubation, pneumonia, aspiration, unanticipated need for noninvasive respiratory support, acute respiratory distress, and mortality from respiratory arrest. The secondary outcome was the adequacy of operating conditions as assessed by blinded surgeon survey (including a rating of surgical conditions on a Likert scale from 1 = poor to 5 = excellent), anesthesiologist report, and patient questionnaire. MEASUREMENTS AND MAIN RESULTS: The composite incidence of PPCs did not differ between groups (8 of 50 patients in both groups; 16%). Mean surgeon rating of surgical conditions was lower in the SUX group (4.65 ± 0.85 v 4.96 ± 0.20, p = 0.02). CONCLUSION: Although avoiding nondepolarizing NMBA is feasible, doing so worsened operating conditions and did not reduce the incidence of postoperative pulmonary complications.

The locomotor system of the ocean sunfish Mola mola (L.): role of gelatinous exoskeleton, horizontal septum, muscles and tendons.

Adult ocean sunfish are the heaviest living teleosts. They have no axial musculature or caudal fin. Propulsion is by unpaired dorsal and anal fins; a pseudocaudal fin ('clavus') acts as a rudder. Despite common perception, young sunfish are active predators that swim quickly, beating their vertical fins in unison to generate lift-based propulsion and attain cruising speeds similar to salmon and marlin. Here we show that the thick subcutaneous layer (or 'capsule'), already known to provide positive buoyancy, is also crucial to locomotion. It provides two compartments, one for dorsal fin musculature and one for anal fin muscles, separated by a thick, fibrous, elastic horizontal septum that is bound to the capsule itself, the roof of the skull and the dorsal surface of the short vertebral column. The compartments are braced sagittally by bony haemal and neural spines. Both fins are powered by white muscles distributed laterally and red muscles located medially. The anal fin muscles are mostly aligned dorso-ventrally and have origins on the septum and haemal spines. Dorsal fin muscles vary in orientation; many have origins on the capsule above the skull and run near-horizontally and some bipennate muscles have origins on both capsule and septum. Such bipennate muscle arrangements have not been described previously in fishes. Fin muscles have hinged tendons that pass through capsular channels and radial cartilages to insertions on fin rays. The capsule is gelatinous (89.8% water) with a collagen and elastin meshwork. Greasy in texture, calculations indicate capsular buoyancy is partly provided by lipid. Capsule, septum and tendons provide elastic structures likely to enhance muscle action and support fast cruising.

Low-income adults' perceptions of farmers' markets and community-supported agriculture programmes.

OBJECTIVE: To better understand low-income adults' attitudes towards participating in farmers' markets, community-supported agriculture (CSA) and nutrition education programming. DESIGN: Focus groups were held with a diverse sample of adults. Interviews were transcribed verbatim and analysed using thematic analysis. SETTING: Three affordable housing communities in Washington, DC, USA. SUBJECTS: Participants included twenty-eight residents of the three affordable housing communities. RESULTS: Four major themes emerged across groups, along with several sub-themes within each theme. These included: (i) perceptions of farmers' markets (benefits, barriers, current participation and knowledge); (ii) perceptions of CSA (benefits, barriers and questions/concerns); (iii) need/interest in additional programming (nutrition education, non-nutrition education, qualities of programming and perceived barriers); and (iv) current health knowledge and behaviours (dietary behaviours, health recommendations and health concerns). CONCLUSION: Adults living in urban, affordable housing communities desire access to healthy foods, but are limited by cost. Programmes could have a higher likelihood of success if they accept benefits like SNAP (the Supplemental Nutrition Assistance Program), are heavily marketed and incorporate culturally relevant nutrition education components.

A Qualitative Examination of Health Barriers and Facilitators Among African American Mothers in a Subsidized Housing Community.

Although African American families are at particular risk for obesity and its associated health comorbidities, few interventions have directly targeted low-income members of this group living in subsidized public housing. Using a consensual qualitative research approach, we conducted 11 interviews with African American mothers living in two public housing communities to enhance understanding of their perceived barriers and facilitators to health. Five primary domains emerged, including barriers (access, financial, personal, and neighborhood concerns), resources (personal and community), current behaviors (diet, physical activity, and program participation), definition of health (mental well-being, physical well-being, and health behaviors), and needs/interests in programming (health behavior-specific programs, non-health-related programs, child-focused programming, and qualities of programs and their leaders). Results demonstrate the complex interaction among social, environmental, and personal factors on health behaviors for this priority population, and highlight the need for community members' involvement in the development of community-based obesity prevention programming.

Does this Tweet make me look fat? A content analysis of weight stigma on Twitter.

PURPOSE: Weight stigma involves stereotyping individuals based on body size. Individuals with obesity face weight stigma in many areas of their lives, and consequences can include impairment of mental and physical health, relationships, and academic performance. Weight-stigmatizing messages are pervasive in mass media, but the degree and characteristics of its presence within new-media social environments remain comparatively unknown. METHODS: This study examined weight stigma on Twitter by coding Tweet content that included the word "fat" within a 4-h timeframe (N = 4596). Coding marked demographic characteristics represented in content, messages about weight, and perceived intent of the message. RESULTS: Of all messages, 56.57 % were negative and 32.09 % were neutral. Of those containing weight-stigmatizing messages (n = 529), themes relating to fatness included: gluttonous (48.58 %), unattractive (25.14 %), not sexually desirable (2.65 %), sedentary (13.80 %), lazy (5.86 %), and stupid (4.16 %). CONCLUSIONS: Weight-stigmatizing messages are evident in the increasingly important arena of social media, and themes appear similar to those that emerge in other forms of media. Prevention and intervention body image programs should consider targeting social networks to help individuals manage societal messages.
