Cost-effectiveness of medication therapy management among Medicare population and across racial/ethnic groups.

BACKGROUND: Inappropriate medication utilization among older adults is a pressing concern in the United States, owing to its high prevalence and the consequential detrimental impact it engenders. The adverse effects stemming from the inappropriate use of medication may be unequally borne by racial/ethnic minority populations, calling for greater efforts towards promoting equity in healthcare. The study objective was to assess the cost-effectiveness of Medication Therapy Management (MTM) services among Medicare beneficiaries and across racial/ethnic groups. METHODS: Medicare administrative data from 2016 to 2017 linked to Area Health Resources Files were used to analyze Medicare fee-for-service patients aged 65 or above with continuous Parts A/B/D coverage. The intervention group included new MTM enrollees in 2017; the control group referred to patients who met the general MTM eligible criteria but did not enroll in 2016 or 2017. The 2 groups were matched using a propensity score method. Effectiveness was evaluated as the proportion of appropriate medication utilization based on performance measures developed by the Pharmacy Quality Alliance. Costs were computed as total healthcare costs from Medicare perspective. A multivariable net benefit regressions with a classic linear model and Bayesian analysis were utilized. Net benefit was calculated based on willingness-to-pay thresholds at various multiples of the gross domestic product in 2017. Three-way interaction terms among dummy variables for MTM enrollment, 2017, and racial/ethnic minority groups were incorporated in a difference-in-differences study design. RESULTS: After adjusting for patient characteristics, the findings indicate that MTM receipt was associated with incremental net benefit among each race and ethnicity. For instance, the net benefit of MTM among the non-Hispanic White patients was $2498 (95% confidence interval = $1609, $3386) at a willingness-to-pay value of $59,908. The study found no significant difference in net benefits for MTM services between minority and White patients. CONCLUSION: The study provides evidence that MTM is a cost-effective tool for managing medication utilization among the Medicare population. However, MTM may not be cost-effective in reducing racial/ethnic disparities in medication utilization in the short term. Further research is needed to understand the long-term cost-effectiveness of MTM on racial/ethnic disparities.

Evaluating the correlation of sclerostin levels with obesity and type 2 diabetes in a multiethnic population living in Kuwait.

Obesity and Type 2 Diabetes Mellitus (T2DM) are intricate metabolic disorders with a multifactorial etiology, often leading to a spectrum of complications. Recent research has highlighted the impact of these conditions on bone health, with a particular focus on the role of sclerostin (SOST), a protein molecule integral to bone metabolism. Elevated circulating levels of SOST have been observed in patients with T2DM compared to healthy individuals. This study aims to examine the circulating levels of SOST in a multiethnic population living in Kuwait and to elucidate the relationship between SOST levels, obesity, T2DM, and ethnic background. The study is a cross-sectional analysis of a large cohort of 2083 individuals living in Kuwait. The plasma level of SOST was measured using a bone panel multiplex assay. The study found a significant increase in SOST levels in individuals with T2DM (1008.3 pg/mL, IQR-648) compared to non-diabetic individuals (710.6 pg/mL, IQR-479). There was a significant gender difference in median SOST levels, with males exhibiting higher levels than females across various covariates (diabetes, IR, age, weight, and ethnicity). Notably, SOST levels varied significantly with ethnicity: Arabs (677.4 pg/mL, IQR-481.7), South Asians (914.6 pg/mL, IQR-515), and Southeast Asians (695.2 pg/mL, IQR-436.8). Furthermore, SOST levels showed a significant positive correlation with gender, age, waist circumference, systolic and diastolic blood pressure, fasting blood glucose, HbA1c, insulin, total cholesterol, triglycerides, HDL, LDL, ALT, and AST (p-Value ≥0.05). South Asian participants, who exhibited the highest SOST levels, demonstrated the most pronounced associations, even after adjusting for age, gender, BMI, and diabetes status (p-Value ≥0.05). The observed correlations of SOST with various clinical parameters suggest its significant role in the diabetic milieu, particularly pronounced in the South Asian population compared to other ethnic groups.

Racial and Ethnic Disparities in Initiation of Direct Oral Anticoagulants Among Medicare Beneficiaries.

Importance: The influence of race and ethnicity on initiation of direct oral anticoagulants (DOACs) is relatively understudied in Medicare data. Objective: To investigate disparities in the initiation of DOACs compared with warfarin by race, ethnicity, and social vulnerability. Design, Setting, and Participants: This retrospective cohort study used a 50% sample of Medicare fee-for-service data from January 1, 2010, to December 31, 2019 (mean patient enrollment duration, 7.7 years). Analysis took place between January 2023 and February 2024. A cohort of older adults (aged ≥65 years) with atrial fibrillation who newly initiated warfarin or DOACs (dabigatran, rivaroxaban, apixaban, and edoxaban) was identified. Exposure: Patients were classified as non-Hispanic White, non-Hispanic Black, and Hispanic. Main Outcomes and Measures: The likelihood of starting use of DOACs compared with warfarin was modeled, adjusting for race, ethnicity, age, sex, county-level social vulnerability, and other clinical factors. Results: Among 950 698 anticoagulation initiations, consisting of 680 974 DOAC users and 269 724 warfarin users (mean [SD] age, 78.5 [7.6] years; 52.6% female), 5.2% were Black, 4.3% were Hispanic, and 86.7% were White. During the 10-year study period, DOAC use increased for all demographic groups. After adjustment, compared with White patients, Black patients were 23% less likely (adjusted odds ratio [AOR, 0.77; 95% CI, 0.75-0.79) and Hispanic patients were 13% less likely (AOR, 0.87; 95% CI, 0.85-0.89) to initiate DOAC use. Disparities in DOAC initiation were greatest among Black patients in the earlier years but attenuated during the study period. For instance, in 2010, the OR of Black patients initiating DOACs was 0.54 (95% CI, 0.50-0.57), attenuating linearly over time to 0.69 by 2013 (95% CI, 0.65-0.74) and 0.83 (95% CI, 0.78-0.89) by 2017. By 2019, these differences became nonsignificant (OR, 1.08; 95% CI, 0.99-1.18). Conclusions and Relevance: In this cohort study of Medicare patients with atrial fibrillation, Black and Hispanic patients were less likely to initiate DOACs for atrial fibrillation, although these differences diminished over time. Identifying the factors behind these early disparities is crucial for ensuring equitable access to novel therapies as they emerge for Black and Hispanic populations.

Using a co-design methodological approach to optimize perioperative nursing care for older adult patients from ethnically diverse backgrounds: a study protocol.

This article outlines the use of a co-design methodological approach aimed at optimizing perioperative care experiences for ethnically diverse older adults and their family carers. The research involved three phases. In Phase 1, the foundation was established with the formation of a Core Advisory Group comprising key informants, including health consumers. This initial phase focused on forming relationships and conducting a literature review to inform subsequent stages of the research. Phase 2 progressed to data collection, where a qualitative survey on perioperative experiences was conducted. Semi-structured interviews were held with patients, their family carers, and perioperative staff. Phase 3 advanced the co-design process through a workshop involving patients, family carers, perioperative staff, and key stakeholders. Workshop participants collaborated on potential practice changes, proposing strategies for future clinical implementation. While data analysis and reporting for Phases 2 and 3 are forthcoming, the continued involvement of the Core Advisory Group ensures ongoing consensus-building on health consumer needs. This methodology article adopts a prospective stance, with findings to be presented in subsequent scholarly works. Use of this methodology will help to determine how the use of a co-design approach may impact the development of culturally responsive perioperative nursing care for those from ethnically diverse communities.

The interrelation between microbial immunoglobulin coating, vaginal microbiota, ethnicity, and preterm birth.

BACKGROUND: Vaginal microbiota composition is associated with spontaneous preterm birth (sPTB), depending on ethnicity. Host-microbiota interactions are thought to play an important underlying role in this association between ethnicity, vaginal microbiota and sPTB. METHODS: In a prospective cohort of nulliparous pregnant women, we assessed vaginal microbiota composition, vaginal immunoglobulins (Igs), and local inflammatory markers. We performed a nested case-control study with 19 sPTB cases, matched based on ethnicity and midwifery practice to 19 term controls. RESULTS: Of the 294 included participants, 23 pregnancies ended in sPTB. We demonstrated that Lactobacillus iners-dominated microbiota, diverse microbiota, and ethnicity were all independently associated with sPTB. Microbial Ig coating was associated with both microbiota composition and ethnicity, but a direct association with sPTB was lacking. Microbial IgA and IgG coating were lowest in diverse microbiota, especially in women of any ethnic minority. When correcting for microbiota composition, increased microbial Ig coating correlated with increased inflammation. CONCLUSION: In these nulliparous pregnant women, vaginal microbiota composition is strongly associated with sPTB. Our results support that vaginal mucosal Igs might play a pivotal role in microbiota composition, microbiota-related inflammation, and vaginal community disparity within and between ethnicities. This study provides insight in host-microbe interaction, suggesting that vaginal mucosal Igs play an immunomodulatory role similar to that in the intestinal tract. Video Abstract.

Homophily and social mixing in a small community: Implications for infectious disease transmission.

Community mixing patterns by sociodemographic traits can inform the risk of epidemic spread among groups, and the balance of in- and out-group mixing affects epidemic potential. Understanding mixing patterns can provide insight about potential transmission pathways throughout a community. We used a snowball sampling design to enroll people recently diagnosed with SARS-CoV-2 in an ethnically and racially diverse county and asked them to describe their close contacts and recruit some contacts to enroll in the study. We constructed egocentric networks of the participants and their contacts and assessed age-mixing, ethnic/racial homophily, and gender homophily. The total size of the egocentric networks was 2,544 people (n = 384 index cases + n = 2,160 recruited peers or other contacts). We observed high rates of in-group mixing among ethnic/racial groups compared to the ethnic/racial proportions of the background population. Black or African-American respondents interacted with a wider range of ages than other ethnic/racial groups, largely due to familial relationships. The egocentric networks of non-binary contacts had little age diversity. Black or African-American respondents in particular reported mixing with older or younger family members, which could increase the risk of transmission to vulnerable age groups. Understanding community mixing patterns can inform infectious disease risk, support analyses to predict epidemic size, or be used to design campaigns such as vaccination strategies so that community members who have vulnerable contacts are prioritized.

Power Dynamics Perpetuate DEI Inaction: A Qualitative Study of Community Health Clinic Teams.

PURPOSE: Despite increased clinician awareness of systemic racism, lack of substantial action toward antiracism exists within health care. Clinical staff perspectives, particularly those of racial-ethnic minorities/persons of color (POC) who disproportionately occupy support staff roles with less power on the team, can yield insights into barriers to progress and can inform future efforts to advance diversity, equity, and inclusion (DEI, also referred to as EDI) within health care settings. This qualitative study explored the perspectives of staff members on race and role power dynamics within community health clinic teams. METHODS: We conducted semistructured 45-minute interviews with staff members working in community health clinics in a large urban health care system from May to July 2021. We implemented purposeful recruitment to oversample POC and support staff and to achieve equal representation from the 13 community health clinics in the system. Interviews were audio recorded, transcribed, and analyzed over 6 months using a critical-ideological paradigm. Themes reflecting experiences related to race and role power dynamics were identified. RESULTS: Our cohort had 60 participants: 42 (70%) were support staff (medical assistants, front desk clerks, care navigators, nurses) and 18 (30%) were clinicians and clinic leaders. The large majority of participants were aged 26 to 40 years (60%), were female (83%), and were POC (68%). Five themes emerged: (1) POC face hidden challenges, (2) racial discrimination persists, (3) power dynamics perpetuate inaction, (4) interpersonal actions foster safety and equity, and (5) system-level change is needed for cultural shift. CONCLUSIONS: Understanding the race and role power dynamics within care teams, including experiences of staff members with less power, is critical to advancing DEI in health care.

Wild edible vegetables of ethnic communities of Mizoram (Northeast India): an ethnobotanical study in thrust of marketing potential.

BACKGROUND: Assessment of wild edible vegetables (WEVs) from the ethnobotanical approach is a significant key to understanding indigenous knowledge systems. The available literature has revealed a tremendous decline in knowledge of WEVs over the last few decades. The main purpose of this study was to document and analyse the traditional knowledge of WEVs among the two major ethnic groups of Mizoram regarding their use and the diversity associated with the importance of traditional medicines. Secondly, a market survey will be conducted to determine the status of available WEVs. METHODS: This study conducted an ethnobotanical survey among 72 informants through semi-structured interviews and questionnaires besides direct field observations. The documented data were quantitatively analysed using various ethnobotanical indices, including Informant's consensus factor (ICF), Fidelity level value (Fl), and Direct matrix ranking (DMR). A marketing survey was conducted in the Bara Bazar, Mizoram's most prominent local market. A total of 38 vendor informants were interviewed to observe and collect the price of commonly sold WEVs. RESULTS: A total of 70 WEVs, distributed in 58 genera under 36 families, were documented and identified. Of these, 33 WEVs were of medicinal importance. Leafy vegetables were documented as the most frequently consumed parts (55.71%). The majority (44.29%) of the plants documented were consumed in fried form. The highest level of agreement among informants for food used categories was observed for plants combined with dry fish (ICF = 1). The Informant's consensus factor (ICF) of disease categories ranges from 0.75 to 1, with the highest being reported for convulsion (ICF = 1), sleep inducer (ICF = 1), and antiseptic (ICF = 1). Picria fel-terrae was the most preferred plant for hypertension treatment (100% FL). Direct matrix ranking (DMR) indicated that Dysoxylum excelsum was highly utilized by the inhabitant for multipurpose species (DMR = 64). Jaccard similarity index (JI) between the two ethnic groups was revealed at 1.26. Forty-seven WEVs were found to be commercialized in the Bara Bazar market, Aizawl, with a price range from 0.1 to 2.4 USD. Ensete superbum was reported as near threatened per the IUCN Red List of Threatened Species. CONCLUSION: This work highlighted the importance and rich diversity of WEVs in Mizoram, which are presently used among different age groups for food and medicine. Informants have good knowledge of WEVs, which was shared to a great extent among the inhabitants; this legacy of traditional culture must be conserved. This study further suggests a priority setting for conserving multipurpose WEVs in human-inhabited sites, investigating the recorded species' nutritional properties and pharmacological activities.

Multiple job holding, working hours, and hypertension by race/ethnicity and sex.

The number of Americans with multiple jobs is increasing and multiple jobholders work more hours per week. However, the associations between multiple jobholding and hypertension are unknown. The aim of this study was to examine the associations of multiple jobholding with hypertension and determine whether weekly working hours moderated this association. Data from the 2015 National Health Interview Survey on adults (age ≥18 years) were used and included participants who self-identified as non-Hispanic Asian, non-Hispanic Black, Hispanic, or non-Hispanic White in the U.S. (n = 16,926), The associations of multiple jobholding with self-reported hypertension by sex were assessed using modified Poisson regressions. Both the number of working hours per week and race/ethnicity were assessed as moderators using multiplicative interaction terms. Multiple jobholding was not associated with hypertension among women. However, there was a significant three-way interaction such that multiple jobholding was associated with hypertension among non-Hispanic Black men who worked ≥55 hours per week (relative risk = 1.02, 95% confidence interval = 1.01-1.05). The results suggest that the associations between multiple jobholding, number of working hours, and hypertension should be examined at the intersection of race/ethnicity and sex. Future studies should further characterize multiple jobholding and hypertension among non-Hispanic Black men.

Estimates of SARS-CoV-2 Hospitalization and Fatality Rates in the Prevaccination Period, United States.

Few precise estimates of hospitalization and fatality rates from COVID-19 exist for naive populations, especially within demographic subgroups. We estimated rates among persons with SARS-CoV-2 infection in the United States during May 1-December 1, 2020, before vaccines became available. Both rates generally increased with age; fatality rates were highest for persons >85 years of age (24%) and lowest for children 1-14 years of age (0.01%). Age-adjusted case hospitalization rates were highest for African American or Black, not Hispanic persons (14%), and case-fatality rates were highest for Asian or Pacific Islander, not Hispanic persons (4.4%). Eighteen percent of hospitalized patients and 44.2% of those admitted to an intensive care unit died. Male patients had higher hospitalization (6.2% vs. 5.2%) and fatality rates (1.9% vs. 1.5%) than female patients. These findings highlight the importance of collecting surveillance data to devise appropriate control measures for persons in underserved racial/ethnic groups and older adults.

Priorities for health outcomes in glaucoma in an ethnically diverse UK cohort: an observational study.

OBJECTIVES: To assess whether patients from minority ethnic groups have different perceptions about the quality-of-life outcomes that matter most to them. DESIGN: Cross-sectional observational study. SETTING: High volume eye centres serving the most ethnically diverse region in the UK, recruiting from July 2021 to February 2022. PARTICIPANTS: 511 patients with primary open-angle glaucoma and the predisease state of ocular hypertension. MAIN OUTCOME MEASURES: The main outcome was participants' self-reported priorities for health outcomes. RESULTS: Participants fell into one of four clusters with differing priorities for health outcomes, namely: (1) vision, (2) drop freedom, (3) intraocular pressure and (4) one-time treatment. Ethnicity was the strongest determinant of cluster membership after adjusting for potential confounders. Compared with white patients prioritising vision alone, the OR for black/black British patients was 7.31 (95% CI 3.43 to 15.57, p<0.001) for prioritising drop freedom; 5.95 (2.91 to 12.16, p<0.001) for intraocular pressure; and 2.99 (1.44 to 6.18, p=0.003) for one-time treatment. For Asian/Asian British patients, the OR was 3.17 (1.12 to 8.96, p=0.030) for prioritising intraocular pressure as highly as vision. Other ethnic minority groups also had higher ORs for prioritising health outcomes other than vision alone: 4.50 (1.03 to 19.63, p=0.045) for drop freedom and 5.37 (1.47 to 19.60, p=0.011) for intraocular pressure. CONCLUSIONS: Ethnicity is strongly associated with differing perceptions about the health outcomes that matter. An individualised and ethnically inclusive approach is needed when selecting and evaluating treatments in clinical and research settings.

Comparative cephalometric study of the airways between different ethnic groups with normal occlusion.

OBJECTIVE: This study aimed to compare the nasopharynx and oropharynx airway dimensions of Caucasians, Blacks, Japanese, Japanese Brazilians, and Black Caucasians. METHODS: A sample of 216 lateral radiographs of untreated young Brazilian subjects (mean age of 12.94 years; SD 0.88) were divided into five groups: Black Caucasian, Black, Caucasian, Japanese, and Japanese Brazilian. Lateral radiographs were used to measure the oropharynx (from the midpoint on the soft palate to the closest point on the anterior pharyngeal wall) and the nasopharynx (from the intersection of the posterior border of the tongue and the inferior border of the mandible to the closest point on the posterior pharyngeal wall). Analyses of variance (ANOVA) and Tukey's test were performed (p< 0.05). RESULTS: The linear dimension of the oropharynx was similar among the different ethnic groups. Caucasian individuals presented a significantly greater linear dimension of the nasopharynx than Black Caucasian and Black individuals. CONCLUSIONS: All the groups had similar buccopharyngeal values. However, Caucasian individuals had significantly higher values when compared to Black Caucasians and Black individuals.

Alpha Diversity Indices as Indicators of the Variability of Gut Microbiota in Obese Adolescents of Different Ethnicities.

We compared alpha diversity indices of the intestinal microbiota in adolescents with obesity and normal body weight, taking into account their ethnicity. Intestinal biocenosis was studied by metasequencing of amplicon libraries of V3-V4 fragments of the 16S rRNA gene. The alpha diversity of the microbiota was assessed using classical and alternative indices. Statistically significant differences in intestinal microbiota were observed between Russians with obesity and Buryats with normal body weight, as well as between Russians with obesity and Buryats with obesity when assessing the Shannon-Weaver, Chao1 indices, Faith phylogenetic diversity index, ACE, Fisher, Gini coefficient, Margalef, and Menkhinik indices. It was shown that alpha diversity indices can be used to assess significance of differences and variability of the intestinal microbiota in multifactorial diseases such as obesity in adolescents; however, the scope of application of the criteria should be considered.

Ethnobotanical insights into the traditional food plants of the Baiku Yao community: a study of cultural significance, utilization, and conservation.

BACKGROUND: The Baiku Yao, primarily residing in Guangxi and Guizhou provinces of China, is a distinctive branch of the Yao ethnic group, known for their profound cultural preservation and unique ethnobotanical knowledge. This study investigates the Baiku Yao community's utilization of traditional food plants, focusing on the relationship between their dietary practices and the local biodiversity within their mountainous living environment. It aims to illuminate the cultural significance and survival strategies embedded in their ethnobotanical knowledge, highlighting the potential for sustainable living and biodiversity conservation. METHODS: Through ethnobotanical surveys, key informant interviews, and quantitative analysis techniques such as the cultural food significance index (CFSI) and relative frequency of citations (RFC), this research systematically documents the diversity and cultural importance of edible plants in the Baiku Yao community. The study assesses how these plants contribute to the community's diet, traditional medicine, and overall cultural practices. RESULTS: A total of 195 traditional edible plants were documented, belonging to 142 genera and 68 families, with a significant concentration in certain families such as Asteraceae, Rosaceae, and Fabaceae. The Baiku Yao diet prominently features herbaceous plants, with wild (103 species) and cultivated (89 species) varieties as diverse food sources. They utilize various plant parts, particularly fruits and leaves, for multiple purposes, including nutrition, medicine, and fodder. Their processing techniques, from raw to fermented, showcase a rich culinary tradition and emphasize a holistic use of plants for enhancing diet and health in a concise overview. The RFC and CFSI analyses reveal a deep cultural reliance on a variety of plant species, with a notable emphasis on vegetables, fruits, spices, and medicinal herbs. Specific plants like Zingiber officinale, Zea mays, and Oryza sativa were highlighted for their high cultural significance. The study also uncovers the multifunctional use of these plants, not only as food but also for medicinal purposes, fodder, and other cultural applications, reflecting the Baiku Yao's profound ecological wisdom and their harmonious coexistence with nature. CONCLUSION: The findings emphasize the rich ethnobotanical knowledge possessed by the Baiku Yao, underscoring the importance of documenting, safeguarding, and transmitting this invaluable traditional knowledge. This study contributes to a deeper understanding of cultural heritage and biodiversity conservation, advocating for concerted efforts to protect such traditional practices against the threats of modernization and cultural erosion.

Racial and Ethnic Disparity in Approach for Pediatric Intensive Care Unit Research Participation.

Importance: While disparities in consent rates for research have been reported in multiple adult and pediatric settings, limited data informing enrollment in pediatric intensive care unit (PICU) research are available. Acute care settings such as the PICU present unique challenges for study enrollment, given the highly stressful and emotional environment for caregivers and the time-sensitive nature of the studies. Objective: To determine whether race and ethnicity, language, religion, and Social Deprivation Index (SDI) were associated with disparate approach and consent rates in PICU research. Design, Setting, and Participants: This retrospective cohort study was performed at the Children's Hospital of Philadelphia PICU between July 1, 2011, and December 31, 2021. Participants included patients eligible for studies requiring prospective consent. Data were analyzed from February 2 to July 26, 2022. Exposure: Exposures included race and ethnicity (Black, Hispanic, White, and other), language (Arabic, English, Spanish, and other), religion (Christian, Jewish, Muslim, none, and other), and SDI (composite of multiple socioeconomic indicators). Main Outcomes and Measures: Multivariable regressions separately tested associations between the 4 exposures (race and ethnicity, language, religion, and SDI) and 3 outcomes (rates of approach among eligible patients, consent among eligible patients, and consent among those approached). The degree to which reduced rates of approach mediated the association between lower consent in Black children was also assessed. Results: Of 3154 children included in the study (median age, 6 [IQR, 1.9-12.5] years; 1691 [53.6%] male), rates of approach and consent were lower for Black and Hispanic families and those of other races, speakers of Arabic and other languages, Muslim families, and those with worse SDI. Among children approached for research, lower consent odds persisted for those of Black race (unadjusted odds ratio [OR], 0.73 [95% CI, 0.55-0.97]; adjusted OR, 0.68 [95% CI, 0.49-0.93]) relative to White race. Mediation analysis revealed that 51.0% (95% CI, 11.8%-90.2%) of the reduced odds of consent for Black individuals was mediated by lower probability of approach. Conclusions and Relevance: In this cohort study of consent rates for PICU research, multiple sociodemographic factors were associated with lower rates of consent, partly attributable to disparate rates of approach. These findings suggest opportunities for reducing disparities in PICU research participation.
