Risk factors associated with 1-year mortality after osteoporotic hip fracture in Hawai'i: higher mortality risk among Native Hawaiians and other Pacific Islanders.

We studied factors affecting osteoporotic hip fracture mortality in Hawai'i, a region with unique geography and racial composition. Men, older adults, higher ASA score, lower BMI, and NHPI race were associated with higher mortality. This is the first study demonstrating increased mortality risk after hip fracture in NHPI patients. PURPOSE: To estimate mortality rates and identify specific risk factors associated with 1-year mortality after osteoporotic hip fracture in Hawai'i. METHODS: A retrospective review of adults (≥ 50 years) hospitalized with an osteoporotic hip fracture at a large multicenter healthcare system in Hawai'i from 2011 to 2019. The Kaplan-Meier curves and log-rank tests examined survival probability by sex, age group, race/ethnicity, primary insurance, body mass index (BMI), and American Society of Anesthesiologists (ASA) physical status classification. After accounting for potential confounders, adjusted hazard ratios (aHR) and 95% confidence intervals (CI) were obtained from Cox proportional hazards regression models. RESULTS: We identified 1755 cases of osteoporotic hip fracture. The cumulative mortality rate 1 year after fracture was 14.4%. Older age (aHR 3.50; 95% CI 2.13-5.76 for ≥ 90 vs 50-69), higher ASA score (aHR 5.21; 95% CI 3.09-8.77 for ASA 4-5 vs 1-2), and Native Hawaiian/Pacific Islander (NHPI) race (aHR 1.84; 95% CI 1.10-3.07 vs. White) were independently associated with higher mortality risk. Female sex (aHR 0.64; 95% CI 0.49-0.84 vs male sex) and higher BMI (aHR 0.35; 95% CI 0.18-0.68 for obese vs underweight) were associated with lower mortality risk. CONCLUSION: In our study, men, older adults, higher ASA score, lower BMI, and NHPI race were associated with significantly higher mortality risk after osteoporotic hip fracture. NHPIs are an especially vulnerable group and comprise a significant portion of Hawai'i's population. Further research is needed to address the causes of higher mortality and interventions to reduce hip fractures and associated mortality.

HPV Vaccine Awareness, Past Behaviors, and Future Intentions Among a Diverse Sample of Fathers Aged 27 to 45 Years: A National Survey.

Men aged 27 to 45 are eligible for human papillomavirus (HPV) vaccination as of 2019, yet relatively little is known about whether they have received or intend to receive it. We conducted a cross-sectional, online survey among fathers aged 27 to 45 between March and April 2022, to assess associations between HPV vaccination awareness, behaviors, intentions, and psychosocial constructs from the Health Belief Model. We examined the characteristics of those who had (a) heard of the HPV vaccine, (b) already received ≥ 1 dose, and (c) intentions for future vaccination among those who had never been vaccinated. Among 400 men who completed the survey, 32% were not aware of the HPV vaccine. Among those who were aware, 41% had received ≥ 1 dose. Sixty-three percent of unvaccinated men reported that they intended to get vaccinated in the future. Multivariable logistic regression analyses revealed that age and race/ethnicity were associated with having been vaccinated previously. Among the unvaccinated, multivariable logistic regression analyses revealed that those with a higher perceived risk of HPV-associated cancer had 3.73 greater odds of reporting they would seek vaccination compared to those with lower perceived risk (95% confidence interval [CI] = [1.28, 12.3]). We did not find perceived benefits, barriers, or decision self-efficacy to be related to future vaccine intentions. Since recommendations for this group include shared clinical decision-making, public health efforts should focus on raising awareness of vaccine eligibility, emphasizing risk factors for HPV-associated cancers so that individuals have an accurate perception of risk, and encouraging conversation between men and their providers.

The Prevalence of Hospitalized Parkinson's Disease Patients in All Case Hospitalization among Different Race/Ethnic Subgroups in Hawaii.

Background: Little is known about the epidemiology of Parkinson's disease (PD) patients in Native Hawaiian Or Other Pacific Islander (NHPI) and Asian American (AA) subgroups. Objective: To determine if the prevalence of hospitalized PD patients is different across age groups and racial/ethnic subgroups in Hawaii. Methods: We conducted a retrospective analysis of Hawaii statewide registry (2016-2020) hospitalization data for patients who were 50 years or older. PD patients were identified using an ICD 10 code: Parkinson's Disease (G20) as their primary/secondary hospitalization discharge diagnosis code. Demographic and clinical characteristics among racial/ethnic subgroups (White, Japanese, Filipino, Chinese, NHPI, or Other) were compared. Results: Of 146,844 total hospitalized patients (n = 429,879 records), 1.6% (n = 2,401) had a PD diagnosis. The prevalence of hospitalized PD patients was 2.3% among Japanese and Chinese, followed by 1.7% for Whites, 1.2% for Filipinos and was lowest for NHPI with 0.9% (p < 0.001). As patient's age increased, the prevalence of hospitalized PD patients increased, with 80-84 years old for the highest age range (3.4%). The prevalence of hospitalized PD patients at 80-84 years old varied across the race/ethnic subgroups (Chinese 4.3%, Japanese 4.0%, Whites 3.7%, Filipinos 2.5%, NHPI 2.3%). Conclusions: The prevalence of hospitalized PD patients among all case hospitalizations were lower for NHPI and Filipino compared to that of Japanese, Chinese, and Whites. As patients' age increased, the prevalence of hospitalized patients with PD increased, but less so in NHPI and Filipino groups. Further research is warranted to understand the reason for these observed differences among racial/ethnic subgroups.

Hospital usage for oral and dental conditions in Hawaii: A cross-sectional study using the 2021 Hawaii statewide hospital data.

OBJECTIVE: To investigate the frequency of emergency department (ED) usage primarily for oral/dental conditions in Hawaii and to examine social-demographic factors associated with the identified ED visits. METHODS: This was a cross-sectional study of the 2021 Hawaii Statewide Hospital data. We identified records indicating ED usage and a primary diagnosis of non-traumatic dental conditions (NTDC) and other oral dental conditions (OODC). Descriptive analyses of ED visits for NTDC and OODC were performed to identify vulnerable individuals based on age, sex, race/ethnicity, primary source of payment, county of residence, and total charges per hospital record. A multivariable negative binomial regression model included age, sex, and county of residence was used to obtain adjusted rate ratios (aRR) and 95% confidence intervals (CI) of ED visits for NTDC. RESULTS: Among hospital records with diagnoses for oral or dental conditions (n = 12,336), 97% indicated ED, of which half had an NTDC diagnosis, and the remaining half had an OODC diagnosis. Distinct differences in the characteristics of ED visits were observed between NTDC and OODC. The median total charges per record indicating ED for NTDC and OODC were $1439 and $2439, respectively. A higher rate of ED visits for NTDC was found for those aged 21-44 (aRR [95%CI] = 3.02 [2.41, 3.80], reference: 0-9 years) and those living in a less populous county (Hawaii: 1.73 [1.43, 2.07]; Kauai: 1.78 [1.45, 2.19], reference: Honolulu). CONCLUSIONS: Continued effort to improve dental health is required to reduce ED visits for oral and dental conditions among Hawaii residents, especially for vulnerable individuals.

Racial disparities in hospitalization characteristics among Native Hawaiians, Pacific Islanders and Asian American subgroups with Parkinson's disease.

BACKGROUND: Differences among Native Hawaiians/Pacific Islanders (NHPI) and Asian American (AA) subgroups have not been adequately studied in Parkinson's disease (PD). OBJECTIVE: To determine differences in demographics, comorbidities, and healthcare utilization among NHPI, AA subgroups, and White hospitalized PD patients. METHODS: We conducted a retrospective cross-sectional analysis of Hawai'is statewide registry (2016-2020). Patients with PD were identified using ICD10 code G20 and categorized as White, Japanese, Filipino, Chinese, NHPI, or Other. Variables collected included: age, sex, residence (county), primary source of payment, discharge status, length of stay, in-hospital expiration, Charlson Comorbidity Index (CCI) and Deep Brain Stimulation (DBS) utilization. Bivariate analyses were performed: differences in age and CCI were further examined by multivariable linear regression and proportional odds models. RESULTS: Of 229,238 hospitalizations, 2428 had PD (Japanese: 31.3 %, White: 30.4 %, Filipino: 11.3 %, NHPI: 9.6 %, Chinese: 8.0 %). NHPI were younger compared to rest of the subgroups [estimate in years (95 % CI): Whites: 4.4 (3.0-5.8), Filipinos: 4.3 (2.7-5.9), Japanese: 7.7 (6.4-9.1), Chinese: 7.9 (6.1-9.7), p < 0.001)]. NHPI had a higher CCI compared to White, Japanese, and Chinese (p < 0.001). Among AA subgroups, Filipinos were younger and had a higher CCI compared to Japanese and Chinese (p < 0.001). There were no significant differences in DBS utilization among subgroups. CONCLUSIONS: NHPI and Filipinos with PD were hospitalized at a younger age and had a greater comorbidity burden compared to other AAs and Whites. Further research, ideally prospective studies, are needed to understand these racial disparities.

Subtotal vs total cholecystectomy for difficult gallbladders: A systematic review and meta-analysis.

INTRODUCTION: With severely inflamed gallbladders, laparoscopic cholecystectomy can be difficult and may require procedures like subtotal cholecystectomy (SC). Few studies exist comparing SC and total cholecystectomy (TC) in the setting of severe biliary inflammation. This meta-analysis aims to compare SC and TC for difficult gallbladders. METHODS: Medline-OVID, Embase-OVID, and Cinahl were searched including only studies comparing SC to TC for difficult gallbladders. Primary outcome was CBD injury. Secondary outcomes included bile leak, duodenal injury, retained stone, bleeding, intraabdominal collection, wound infection, reoperation, and mortality. RESULTS: Ten studies were included. Compared to TC, SC significantly lowered the risk for CBD injury (0 â€‹% vs. 1.6 â€‹%, RR 0.30, 95%CI 0.10-0.87) but increased risk of bile leaks (RR 3.5, 95%CI 1.79-6.84), postoperative ERCP (RR 2.86, 95%CI 1.53-5.35), intraabdominal collections (RR 2.55, 95%CI 1.32-4.93), and reoperation (RR 2.92, 95%CI 1.14-7.47). CONCLUSION: SC is a reasonable alternative to difficult gallbladders that may decrease the risk of CBD injuries. Knowing both approaches is crucial to manage the difficult gallbladder while minimizing harm. Further studies are needed to understand the value of SC for difficult cholecystectomy.

A comparison of pre- and post-clinical education learning preferences among medical students who elected to dissect compared to those who did not during the COVID-19 pandemic.

Anatomy instructional methods varied widely during the COVID-19 pandemic and programs are assessing innovations for retention. Learning preferences were assessed among medical students dichotomized as elective dissectors (ED) or non-dissectors (ND) during the COVID-19 partial re-opening in 2020 (preclinical) and again in 2022 after clinical exposure (post-clinical) to assess the viability of elective dissection post-pandemic. A mixed-method approach was used for the assessment of test scores, learning preference surveys, learning activities rankings, and thematic analyses. No significant differences occurred in anatomy examination scores. Dissection was considered useful by both preclinical groups but significantly more so by ED, while the presence of an instructor was significantly preferred by ED although a majority of ND agreed. Elective dissection was significantly preferred by ND but also by a large minority of ED students. Pre- and post-clinical ND believed that elective dissection offered more academic flexibility, did not hinder clinical learning, and did not negatively impact medical education. The corresponding ED stated that confidence improved, clinical experiences were enhanced, and dissection was irreplaceable. Preclinical ND preferred self-learning, while ED students preferred online learning, but these differences largely disappeared post-clinically. Learning activity rankings were not significantly different among all groups (ND, ED, preclinical, and post-clinical). A hybrid laboratory with a virtual learning environment ranked highest across groups and preferences increased over time suggesting that students benefited from this instructional method during clinical exposure. The absence of laboratory experience ranked lowest, and preference decreased over time suggesting that anatomy dissection is valued.

Stepwise Proportional Weighting Algorithm for Single-Race Population Estimation Using Hawai'i Census Data.

Many health and health disparities studies require population prevalence information of various race groups, but the estimation of single-race population sizes using the US Census data has been challenging. For each Census race group, Census only provides the counts of those reported being single race ("race alone") and those reported of that specific race regardless of whether the individuals were multiracial or not ("race alone or in (any) combination"). The issue of how to classify Census multiracial individuals is especially important for the state of Hawai'i due to its large multiracial population. The current study developed the Stepwise Proportional Weighting Algorithm (SPWA) for single-race population estimation using US Census data for major race groups in the Census and their nested detailed races. Additionally, given that "partial Native Hawaiian" has often been treated as "Native Hawaiian" in health disparities studies in Hawai'i, the algorithm can also adjust for the unique partial Native Hawaiian race categorization. This paper describes the estimation process with the SPWA and demonstrates its ability to estimate single-races for the 5 most common race groups in Hawai'i. This new methodology addresses an important concern regarding how to classify multiracial individuals to strengthen health and health disparities research in Hawai'i.

Age and Sex Distributions of 31 Common Racial Groups in Hawai'i: A Shiny Web Application.

Hawai'i is the most ethnically diverse state with the highest proportion of multiracial individuals in the United States. The Stepwise Proportional Weighting Algorithm (SPWA) was developed to bridge the categorization of multiracial Census data into single-race population estimates for common races in Hawai'i. However, these estimates have not been publicly available. A Shiny web application, the Hawai'i Single-Race Categorization Tool, was developed as a user friendly research tool to obtain the age and sex distributions of single-race estimates for common racial groups in Hawai'i. The Categorization Tool implements the SPWA and presents the results in tabular and graphic formats, stratified by sex and age. It also allows the categorization of partial Native Hawaiians as Native Hawaiians in the population estimation. Using this tool, the current paper reports population estimates and distributions for 31 common racial groups using Hawai'i Census 2010 data. Among the major Census races, Asian had the largest population (631 881; 46.5%) in Hawai'i, followed by White (431 635; 31.7%) and Native Hawaiian and Other Pacific Islander (227 588; 16.7%). Among Census detailed races within Asian, Filipino had the largest population estimate (244 730; 18.0%), followed by Japanese (227 165; 16.7%) and Chinese (103 600; 7.6%). Native Hawaiian accounted for 12.3% of the Hawai'i population (166 944). After recategorizing part-Native Hawaiians as Native Hawaiians, Native Hawaiian increased by 150.0%, with the greatest increase among the young. This publicly available tool would be valuable for race-related resource allocation, policy development, and health disparities research in Hawai'i.

Systematic Review for Survey Instruments to Measure Cultural Identification of Native Hawaiians, Pacific Islanders, and Filipinos.

Numerous studies have used survey instruments to measure the degree of cultural identity/identification for a racial group to examine how they identify with their heritage or cultural group. However, only a few systematic reviews have summarized the survey instruments for Native Hawaiians, Pacific Islanders, and Filipinos. This systematic review aimed to summarize reliable and validated survey instruments that assessed the cultural identity/identification of Native Hawaiians, Pacific Islanders, and Filipinos in 3 steps: (1) identifying studies that meet the inclusion and exclusion criteria; (2) evaluating the psychometric properties of the instrument with reported validity and reliability test results; and (3) summarizing the selected studies. A search was conducted in PubMed, PsycINFO, Web of Science, and Health and Psychosocial Instruments databases for published articles related to the cultural identification for the 3 racial groups. Sixteen unique articles met the inclusion/exclusion criteria: 7 for Filipinos, 3 for Native Hawaiians, 1 for Pacific Islanders, 2 for Asian Americans, and 3 for non-specific Indigenous people. Three reviewers assessed the psychometric properties of the 16 articles using the pre-determined criteria and summarized the survey instruments and study outcomes. All the selected articles discussed their survey instrument's validity. This review can serve as a resource for researchers who want to apply a culturally tailored survey instrument for Native Hawaiians, Pacific Islanders, and Filipinos in their research studies.

Correlation Between Intracranial Calcification and Extracranial Stenosis of the Internal Carotid Artery.

Intracranial artery calcification is a marker of vascular atherosclerosis and has a high prevalence worldwide. Both atherosclerosis of the internal carotid artery at the carotid sinus in the neck and intracranial calcification have been associated with ischemic stroke. The relationship between the two has not been well studied. The present study investigated how carotid sinus narrowing could relate to calcification located in the distal intracranial artery at the cavernous carotid. We examined a population not selected for cerebral disease. This retrospective study contained 179 subjects aged 18 years and older from the Hawaii Diagnostic Radiology database. Extracranial internal carotid artery stenosis was determined using the absolute diameter, North American Symptomatic Carotid Endarterectomy Trial, and common carotid artery methods. Calcification was scored using the modified Woodcock method. A positive correlation between intracranial calcification and extracranial carotid stenosis was found using all three methods. Individuals with intracranial calcification were more likely to be older, have a smaller internal carotid artery diameter, and have a greater percent stenosis at the internal carotid artery than those without intracranial artery calcification (p<0.001 for all). These results may help refocus interest in calcification in studies of cerebral vasculature and its correlation with extracranial carotid stenosis.

Are high avidity antibodies to Plasmodium falciparum antigens preferentially transferred across the placenta of premature and term babies?

INTRODUCTION: Transplacental transport of maternal IgG via the neonatal Fc receptor (FcRn) provides babies with passive immunity. Several factors are reported to influence transport, including the avidity of antibodies (Abs) for their cognate antigens. Unfortunately, information on the role of antibody (Ab) avidity is limited. This study investigated if i) antibodies (Abs) with high avidity for 6 Plasmodium falciparum antigens and tetanus toxoid (TTx) were preferentially transferred to premature and term Cameroonian babies and ii) if Ab avidity was increased in babies whose mothers had placental malaria (PM), implicating the involvement of immune complexes. METHODS: Total IgG (mg/ml) and Abs to malarial antigens (AMA1, EBA-175, MSP1-42, MSP2, MSP3, DBL5 of VAR2CSA) and TTx were measured in paired mother-cord samples obtained from premature and term deliveries in Cameroon. Half the women had PM at delivery. Avidity Indices (AIs) were determined by treating antigen-bound-Abs with different molar concentrations of NH4SCN and calculating 50% endpoints. RESULTS: Total IgG and antigen-specific Abs increased in cord blood with gestational age; however, AIs did not. AIs in paired maternal-cord blood samples were strongly associated for all antigens (r = 0.77-0.96). However, no significant different in AIs was found between paired mother-cord blood samples for any of the antigens (p values > 0.05). Similarly, Ab avidity was not increased in cord blood of babies whose mothers had PM or hypergammaglobulinemia. DISCUSSION: Overall, there was no evidence that higher avidity Abs to any of the malarial antigens or TTx were preferentially transferred to Cameroonian babies.

Preferred Location for Human Papillomavirus Self-Sampling for Cervical Cancer Screening.

OBJECTIVE: To examine associations among women's preferred locations for human papillomavirus (HPV) self-sampling in relation to their demographic, social, and health characteristics and their perceived benefits and concerns regarding this procedure. DESIGN: Cross-sectional, descriptive survey. SETTING: Online distribution between March 2022 and April 2022. PARTICIPANTS: People who were assigned female sex at birth and were eligible for cervical cancer screening (N = 367: cis-gender women, n = 364; another gender identity, n = 3). METHODS: We used quota sampling to obtain a racially and ethnically diverse sample. We conducted bivariate analyses to examine differences in participants' preferred locations for HPV self-sampling by sociodemographic and health characteristics. We used a multinomial logistic regression model to examine the associations between preferred HPV self-sampling location, characteristics of participants, and perceived benefits and concerns regarding this procedure. RESULTS: In our sample, 43% (n = 158) of participants preferred HPV self-sampling at the office of a health care provider, 50% (n = 182) preferred HPV self-sampling anywhere (office or home), and 7% (n = 27) did not feel comfortable with HPV self-sampling anywhere. Participants 39 to 45 years of age were more likely to prefer HPV self-sampling anywhere (office or home) than participants 27 to 32 years of age, OR = 2.47, 95% confidence interval (CI) [1.21, 5.06]. Participants who preferred HPV self-sampling anywhere perceived greater benefit related to limited geographic access to a clinic compared to those who preferred office only, OR = 1.82, 95% CI [1.08, 3.07]. Participants who preferred HPV self-sampling anywhere had less concern related to performing the procedure accurately than those who preferred office only, OR = 0.44, 95% CI [0.31, 0.62]. CONCLUSION: HPV self-sampling is an alternative strategy to increase cervical cancer screening. As providers consider implementation of HPV self-sampling, our findings suggest that office and home-based collection strategies should be considered to increase access to cervical cancer screening.

Themes in neuronavigation research: A machine learning topic analysis.

Objective: To understand trends in neuronavigation we employed machine learning methods to perform a broad literature review which would be impractical by manual inspection. Methods: PubMed was queried for articles with "Neuronavigation" in any field from inception-2020. Articles were designated neuronavigation-focused (NF) if "Neuronavigation" was a major MeSH. The latent dirichlet allocation topic modeling technique was used to identify themes of NF research. Results: There were 3896 articles of which 1727 (44%) were designated as NF. Between 1999-2009 and 2010-2020, the number of NF publications experienced 80% growth. Between 2009-2014 and 2015-2020, there was a 0.3% decline. Eleven themes covered 1367 (86%) NF articles. "Resection of Eloquent Lesions" comprised the highest number of articles (243), followed by "Accuracy and Registration" (242), "Patient Outcomes" (156), "Stimulation and Mapping" (126), "Planning and Visualization" (123), "Intraoperative Tools" (104), "Placement of Ventricular Catheters" (86), "Spine Surgery" (85), "New Systems" (80), "Guided Biopsies" (61), and "Surgical Approach" (61). All topics except for "Planning and Visualization", "Intraoperative Tools", and "New Systems" exhibited a monotonic positive trend. When analyzing subcategories, there were a greater number of clinical assessments or usage of existing neuronavigation systems (77%) rather than modification or development of new apparatuses (18%). Conclusion: NF research appears to focus on the clinical assessment of neuronavigation and to a lesser extent on the development of new systems. Although neuronavigation has made significant strides, NF research output appears to have plateaued in the last decade.

Parental Decision Making Regarding COVID-19 Vaccines for Children under Age 5: Does Decision Self-Efficacy Play a Role?

BACKGROUND: COVID-19 vaccines are now available under Emergency Use Authorization for children ages 6 months to 5 years. We examined parents' intentions to vaccinate their children under the age of 5 years and assessed whether their confidence in making an informed decision about vaccination (decision self-efficacy) was associated with these intentions. METHOD: We conducted a cross-sectional online survey of U.S. parents between 23 March and 5 April 2022. We examined associations between parental intention to vaccinate their young children (

Demographic recruitment bias of adults in United States randomized clinical trials by disease categories between 2008 to 2019: a systematic review and meta-analysis.

To promote health equity within the United States (US), randomized clinical trials should strive for unbiased representation. Thus, there is impetus to identify demographic disparities overall and by disease category in US clinical trial recruitment, by trial phase, level of masking, and multi-center status, relative to national demographics. A systematic review and meta-analysis were conducted using MEDLINE, Embase, CENTRAL, and ClinicalTrials.gov, between 01/01/2008 to 12/30/2019. Clinical trials (N = 5,388) were identified based on the following inclusion criteria: study type, location, phase, and participant age. Each clinical trial was independently screened by two researchers. Data was pooled using a random-effects model. Median proportions for gender, race, and ethnicity of each trial were compared to the 2010 US Census proportions, matched by age. A second analysis was performed comparing gender, race, and ethnicity proportions by trial phase, multi-institutional status, quality, masking, and study start year. 2977 trials met inclusion criteria (participants, n = 607,181) for data extraction. 36% of trials reported ethnicity and 53% reported race. Three trials (0.10%) included transgender participants (n = 5). Compared with 2010 US Census data, females (48.3%, 95% CI 47.2-49.3, p < 0.0001), Hispanics (11.6%, 95% CI 10.8-12.4, p < 0.0001), American Indians and Alaskan Natives (AIAN, 0.19%, 95% CI 0.15-0.23, p < 0.0001), Asians (1.27%, 95% CI 1.13-1.42, p < 0.0001), Whites (77.6%, 95% CI 76.4-78.8, p < 0.0001), and multiracial participants (0.25%, 95% CI 0.21-0.31, p < 0.0001) were under-represented, while Native Hawaiians and Pacific Islanders (0.76%, 95% CI 0.71-0.82, p < 0.0001) and Blacks (17.0%, 95% CI 15.9-18.1, p < 0.0001) were over-represented. Inequitable representation was mirrored in analysis by phase, institutional status, quality assessment, and level of masking. Between 2008 to 2019 representation improved for only females and Hispanics. Analysis stratified by 44 disease categories (i.e., psychiatric, obstetric, neurological, etc.) exhibited significant yet varied disparities, with Asians, AIAN, and multiracial individuals the most under-represented. These results demonstrate disparities in US randomized clinical trial recruitment between 2008 to 2019, with the reporting of demographic data and representation of most minorities not having improved over time.

Emergency Room Visits with a Non-Traumatic Dental-Related Diagnosis in Hawaii, 2016-2020.

The purpose of this study was to characterize the frequencies and patterns of emergency room (ER) visits with a non-traumatic dental-related diagnosis among adults (≥21 years old) in Hawaii, United States. This descriptive cross-sectional study used state-level inpatient and outpatient data recorded in Hawaii from 2016 to 2020. We identified dental-related ER visits using the diagnosis codes for non-traumatic dental-related conditions and summarized the frequency, rates, and cumulative total charges of the ER visits. The results show that approximately 30 thousand ER visits between 2016 and 2020 had a dental-related diagnosis. Sixty-seven percent of them had it as a principal diagnosis, amounting to USD 38.7 million total charges over the five years. A high proportion of these visits was found among those aged 21−44 years old (62%), Medicaid beneficiaries (49%), and Native Hawaiians/Part Native Hawaiians (26%). Compared to the proportions of ER visits with a secondary diagnosis, these groups had a higher proportion of ER visits with a principal diagnosis (ps < 0.001). A higher visit rate was found for those aged 21−44 years old and from less-populated counties. These results suggest that oral health disparities in age, socioeconomic status, and race/ethnicity exist in Hawaii. Our findings could provide insight in developing a framework to reduce oral health disparities, particularly among Medicaid beneficiaries and Native Hawaiians. Dental coverage with effective education in multiple dimensions is necessary to reduce non-traumatic dental-related ER visits.

Adequate intake of plant protein foods and moderate intake of animal protein foods are inversely associated with C-reactive protein in US adults with diabetes: A cross-sectional study with National Health and Nutrition Examination Survey.

OBJECTIVE: This study examined the association between index component score levels of the Dietary Approaches to Stop Hypertension (DASH) density-based index and the Healthy Eating Index-2015 (HEI-2015) for protein foods and a high-sensitivity C-reactive protein (hs-CRP) level in US adults with diabetes status. METHODS: This cross-sectional study used data from adult participants (≥20 y) in the National Health and Nutrition Examination Survey 2005-2010 (n = 12070) to obtain hs-CRP levels and index scores in US adults. Odds ratios (OR) of having an elevated hs-CRP (>3.0 mg/L) by score levels of protein food components (low: <80% versus high: ≥80% of the maximum score) were acquired using survey multivariable logistic regression analysis. RESULTS: After adjusting for age group, sex, race/ethnicity, and other potential confounders, participants with a low score were more likely to have an elevated hs-CRP level than those with a high score (DASH plant proteins and HEI-2015 seafood and plant proteins: P < 0.001). Adults with diabetes who had a low score were more likely to have an elevated hs-CRP than adults without diabetes who had a high score (DASH animal proteins: OR 1.53, 95% confidence interval [CI] 1.24-1.87) (DASH plant proteins: OR 1.51, 95% CI 1.22-1.87) (HEI-2015 seafood and plant proteins: OR 1.38, 95% CI 1.16-1.65). Among adults with diabetes, those with a low score for animal protein foods were more likely to have an elevated hs-CRP (DASH animal proteins: OR 1.42, 95% CI 1.11-1.82) than those with a high score. CONCLUSIONS: Moderate intake of animal protein foods and adequate intake of plant protein foods were inversely associated with an elevated hs-CRP level in US adults, especially in those with diabetes. Further investigation is required to establish ideal density-based amounts or proportions of protein food subgroups.

The impact of diabetes and osteoarthritis on the occurrence of stroke, acute myocardial infarction, and heart failure among older adults with non-valvular atrial fibrillation in Hawaii: a retrospective observational cohort study.

BACKGROUND: To date, little is known about cardiovascular disease risks among older adults with non-valvular atrial fibrillation by their association with diabetes and osteoarthritis status, based on longitudinal data with substantial amounts of non-white individuals. The objective of this study was to examine the risks for three cardiovascular diseases: stroke, acute myocardial infarction (AMI), and heart failure (HF), by diabetes and osteoarthritis status among older adults with non-valvular atrial fibrillation in Hawaii. METHODS: We conducted a retrospective observational cohort study for older adults (65 years and older) with non-valvular atrial fibrillation using the Hawaii Medicare data 2009-2017. Their risks for the three cardiovascular diseases by diabetes and osteoarthritis status (diabetes, osteoarthritis, diabetes and osteoarthritis, and without diabetes and osteoarthritis) were examined by multivariable Cox proportional hazard regression models. RESULTS: The analysis included 19,588 beneficiaries followed up for a maximum of 3288 days (diabetes: n = 4659, osteoarthritis: n = 1978, diabetes and osteoarthritis: n = 1230, without diabetes and osteoarthritis: n = 11,721).  Among them, those diagnosed with the cardiovascular diseases were identified (stroke: diabetes n = 837, osteoarthritis n = 315, diabetes and osteoarthritis n = 184, without diabetes and osteoarthritis n = 1630)(AMI: diabetes n = 438, osteoarthritis n = 128, diabetes and osteoarthritis n = 118, without diabetes and osteoarthritis n = 603)(HF: diabetes n = 2254, osteoarthritis n = 764, diabetes and osteoarthritis n = 581, without diabetes and osteoarthritis n = 4272). After adjusting for age, sex, race/ethnicity, and other potential confounders, those with diabetes and osteoarthritis had higher risks for HF (hazard ratio: 1.21 95% confidence interval: 1.10-1.33) than those without diabetes and osteoarthritis. They also had higher risks than those with osteoarthritis for HF. Those with diabetes had higher risks for all three cardiovascular diseases than the other three groups. CONCLUSIONS: Variation in cardiovascular disease risks for older adults with non-valvular atrial fibrillation in Hawaii exists with diabetes and osteoarthritis status.

Does Antibody Avidity to Plasmodium falciparum Merozoite Antigens Increase with Age in Individuals Living in Malaria-Endemic Areas?

High-avidity antibodies (Abs) are acquired after a few Plasmodium falciparum infections in low transmission areas, but it remains unclear if Ab avidity to different merozoite antigens increases with age in individuals with persistent antigenemia and, if so, when a fully mature Ab response occurs. The study used plasma samples collected between 1996 and 1998 from 566 individuals aged 4 to 84 years in Simbok, Cameroon, where residents received an estimated 1.6 infectious mosquito bites/person/night. Plasma samples were examined for Ab levels (median fluorescence intensity [MFI]) and Ab avidity index (AI) (where AI = [MFI after treatment with 2 M NH4SCN/MFI without salt] × 100) using a bead-based multiplex immunoassay for recombinant AMA1, EBA-175, MSP1-42 (3D7, FVO), MSP2 (3D7, Fc27), and MSP3. Blood-smear positivity for P. falciparum declined with age from 54.3% at 4 to 5 years to 18% at 16 to 40 years and <11% at >40 years of age, although most individuals had submicroscopic parasitemia. Ab affinity maturation, based on age-related patterns of median AI, percentage of individuals with AI of ≥50, and strength of association between MFI and AI, occurred at different rates among the antigens; they developed rapidly before age 4 years for AMA1, increased gradually with age for EBA-175 and MSP1 until ∼16 to 25 years, but occurred negligibly for MSP2 and MSP3. In a hyperendemic area with perennial transmission, affinity maturation resulting in an increase in the proportion of high-avidity Abs occurred for some merozoite antigens, in parallel with a decline in malaria slide passivity, but not for others.
