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

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 Hawai'i.

Methods

We conducted a retrospective analysis of Hawai'i 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.

A Choroidal Melanoma With Ciliary Body Involvement in a Young Female

Choroidal melanoma with ciliary body involvement is rare, especially in young adults and Asians. Here, we report the case of a young, healthy Chinese woman who complained of decreased vision in the left eye for one week. Her ocular examination and imaging were suggestive of choroidal melanoma involving the ciliary body. The patient underwent enucleation of the left eye. Close monitoring was needed, as the involvement of the ciliary body in choroidal melanoma is associated with a high risk of metastasis.

Barriers to Alzheimer Disease Clinical Trial Participation in a Minority Population

BACKGROUND

Alzheimer disease (AD), the most common neurodegenerative disorder in the United States, disproportionately burdens minority populations.

OBJECTIVE

To explore barriers to AD clinical trial participation by Asian and Native Hawaiian patients diagnosed with AD or mild cognitive impairment.

METHOD

We surveyed 187 patients with a Mini-Mental State Examination score ≥14 between January 2022 and June 2022. The score cutoff for clinical trial eligibility was set by the institution. Individuals also completed a 15-question telephone survey that assessed demographics, barriers to clinical trial participation, and clinical trial improvement methods.

RESULTS

Forty-nine patients responded, with a response rate of 26%. Asian and Native Hawaiian patients were less likely than White patients to participate in AD trials. The main barrier to participation was a lack of information about AD trials. Providing additional information regarding AD trials to patients and family members were listed as the top two reasons patients would consider participating in a clinical trial.

CONCLUSION

Insufficient information about AD clinical trials is the primary barrier to participation among Asian and Native Hawaiian patients, followed by difficulty coordinating transportation and, in the case of Asians, the time required for clinical trials. Increased outreach, education, and assistance with logistics in these populations should be pursued to improve rates of participation in clinical trials.

Cardiovascular risk of Janus kinase inhibitors compared with biologic disease-modifying antirheumatic drugs in patients with rheumatoid arthritis without underlying cardiovascular diseases: a nationwide cohort study

Objectives: Despite the ethnic differences in cardiovascular (CV) risks and recent increase in the prescription of Janus kinase (JAK) inhibitors, limited evidence is available for their CV outcomes in Asian patients with rheumatoid arthritis (RA). We aimed to compare the major adverse CV events (MACEs) of JAK inhibitors to those of biologic disease-modifying antirheumatic drugs (bDMARDs) in Korean patients with RA without baseline CV disease (CVD). Methods: In a nationwide retrospective cohort study, patients newly diagnosed with RA without a history of CVD between 2013 and 2018 were identified using the National Health Insurance Service database. The cohort was followed up until the end of 2019 for the development of MACEs. Hazard ratios (HRs) for MACEs such as myocardial infarction, stroke, coronary revascularization, or all-cause death, were estimated using Cox proportional hazard regression in a propensity score-matched cohort. Results: In total, 4,230 matched patients with RA were included (846 JAK inhibitor users and 3,384 bDMARD users). The crude incidence rate (95% confidence intervals, CI) per 100 patient-years for MACEs was 0.83 (0.31-1.81) and 0.74 (0.53-1.02) in the JAK inhibitor and bDMARD groups, respectively. The risk of MACEs was not significantly different between JAK inhibitor and bDMARD users with an adjusted HR (95% CI) of 1.28 (0.53-3.11). There were no significant differences in the risk of MACEs between JAK inhibitors and bDMARDs in each subgroup according to the types of bDMARDs, age, sex, Charlson comorbidity index score, and comorbidities. Conclusion: Compared to bDMARDs, JAK inhibitors were not associated with the occurrence of MACEs in Korean patients with RA without a history of CVD.

Race and Ethnic Categories: A Brief Review of Global Terms and Nomenclature

Terminology regarding descriptors of race and ethnicity have been constantly evolving. Due to differences in terminology, data collection, demographics, and group identity, there are numerous challenges in determining what descriptors are suitable and acceptable to all individuals. The National Institutes of Health (NIH) has defined six racial and ethnic categories that should be used for reporting purposes. This review gives a historical background of the definition of the different racial and ethnic categories. This review also aims to define acceptable categories of race and ethnicity to provide guidelines for reports and best practices.

Real-World Evidence on the Efficacy and Tolerability of Tramadol/Dexketoprofen (TRAM/DKP) Fixed-Dose Combination for the Management of Acute Non-surgical Pain in Asian Patients: A Multicentre Retrospective Case Series

INTRODUCTION

Multimodal analgesia is key in the effective management of acute pain. Previous clinical trials have demonstrated good results with the use of a fixed-dose combination (FDC) of tramadol 75 mg and dexketoprofen 25 mg (TRAM/DKP) in acute pain management. However, there is a dearth of real-world evidence on the efficacy and safety of this combination in the management of acute non-surgical pain, especially among Asian patients. The case series reported herein investigates the real-world experiences of physicians and Asian patients with the use of TRAM/DKP FDC in the management of acute non-surgical pain.

METHODS

Data were collected retrospectively on 11 Asian patients across multiple hospitals who had received a short course of TRAM/DKP FDC for acute non-surgical orthopaedic and non-orthopaedic pain. Data on baseline characteristics, medical history, treatment regimen, clinical outcomes, and patient satisfaction were compiled and shared at a peer-to-peer expert meeting in October 2022.

RESULTS

All patients experienced a reduction in pain intensity and were very satisfied with pain management, with a mean satisfaction score of 4.3/5. Five patients (range: 63-74 years) experienced mild adverse events, including nausea, vomiting, and dizziness, which resolved with no need for additional treatment in the majority of cases. No serious adverse events were recorded.

CONCLUSION

Asian patients with acute non-surgical orthopaedic and non-orthopaedic pain achieved good pain control with TRAM/DKP FDC. The regimen was well tolerated, and patients reported high levels of satisfaction with the outcomes, indicating that TRAM/DKP FDC is an effective choice for the control of acute non-surgical pain in Asian patients.

Beyond "Chilling Effects": Latinx and Asian Immigrants' Experiences With Enforcement and Barriers to Health Care

OBJECTIVES

Immigration enforcement policies are associated with immigrants' barriers to health care. Current evidence suggests that enforcement creates a "chilling effect" in which immigrants avoid care due to fear of encountering enforcement. Yet, there has been little examination of the impact of immigrants' direct encounters with enforcement on health care access. We examined some of the first population-level data on Asian and Latinx immigrants' encounters with law and immigration enforcement and assessed associations with health care access.

METHODS

We analyzed the 2018 and 2019 Research on Immigrant Health and State Policy survey in which Asian and Latinx immigrants in California (n=1681) reported on 7 enforcement experiences (eg, racial profiling and deportation). We examined the associations between measures of individual and cumulative enforcement experiences and the usual sources of care and delay in care.

RESULTS

Latinx, compared with Asian respondents, reported the highest levels of enforcement experiences. Almost all individual enforcement experiences were associated with delaying care for both groups. Each additional cumulative experience was associated with a delay in care for both groups (OR=1.30, 95% CI 1.10-1.50). There were no associations with the usual source of care.

CONCLUSION

Findings confirm that Latinx immigrants experience high levels of encounters with the enforcement system and highlight new data on Asian immigrants' enforcement encounters. Direct experiences with enforcement have a negative relationship with health care access. Findings have implications for health systems to address the needs of immigrants affected by enforcement and for changes to health and immigration policy to ensure immigrants' access to care.

United Network for Organ Sharing (UNOS) Database Analysis of Factors Associated With Kidney Transplant Time on Waiting List

INTRODUCTION

 In the United States (U.S.), African Americans and other minority groups have longer wait times for kidney transplantation than Caucasians. To date, many studies analyzing time spent on the waitlist for each race/ethnicity have been done. However, there are few to no studies examining waitlist time after the 2019 policy changes to the geographic distribution of donated kidneys.

METHODS

Data collected from the National Organ Procurement and Transplantation Network database were used to analyze associations between race and time spent on the waitlist for a kidney transplant in the U.S. Additional sub-categorical data were analyzed to determine further associations and potential covariates, such as gender, age, citizenship, primary source of payment, region of transplant center, BMI, Kidney Donor Profile Index (KDPI), renal diagnosis, and presence/type of diabetes. Data were analyzed using odds ratios and validated by Bonferroni-Holm's corrected chi-square tests at confidence intervals of 95% to determine if there are statistically significant differences between transplant time spent on the waitlist and ethnicity, as well as age, diagnosis category, region of transplant center, and KDPI.

RESULTS

Statistically significant increased odds of remaining on the transplant list at two years existed for all non-white races/ethnicities, except those identifying as multiracial. Asian American candidates had the greatest odds of remaining on the waitlist greater than two years in comparison to white candidates: 1.51 times that of a patient categorized as white (odds ratio [OR] 1.51, confidence interval [CI] 1.44-1.57). African American/Black, (OR 1.38, CI 1.34-1.43) Pacific Islander (OR 1.38, CI 1.17-1.63), Hispanic candidates (OR 1.37, CI 1.32-1.41), and American Indian or Native Alaskan candidates (OR 1.23, CI 1.12-1.46) also had increased odds of remaining on the transplant waitlist greater than two years compared to white candidates.

DISCUSSION

In this study, ethnic disparities persisted as a barrier for non-white individuals receiving treatment for end-stage kidney disease, specifically in the context of time spent on the waitlist for a kidney transplant. Further research is needed regarding the causes of these disparities in time spent on the waitlist, such as cultural restrictions in organ donation, racial differences in parameters for organ match, and institutionalized racism in health care practitioners.

Social Determinants of Health: A Need for Evidence-Based Guidelines on How to Capture Data on Underserved Patients

Background . Social determinants of health lead to better cancer care. This multi-site, single-institution study sought to capture data on social determinants of health data in Asian Americans with hepatocellular carcinoma; this group constitutes 60% of patients with this malignancy and are often undertreated or not treated at all. Methods . This study took advantage of an institutional initiative designed to capture and integrate social determinants of health data into the electronic medical record for all patients. Medical records of Asian Americans with hepatocellular cancer were reviewed to acquire data on housing instability, lack of transportation, financial concerns, and social isolation; a score of 1 indicated poor social determinants of health. Results . Of 112 adult Asian American patients with hepatocellular cancer, 22 (20%) were Southeast Asian, and 74 (67%) described English proficiency. A score of 1 (highest risk) was observed in 1 patient (0.9%) for housing instability; 1 (0.9%) lack of transportation; no patient for financial hardship; and 1 (0.9%) for social isolation. However â€" and importantly -- total noncompletion per domain (no question answered within that domain) was observed in 90 patients (80%) for housing instability; 90 (80%) for lack of transportation; 92 (82%) for financial hardship; and 90 (80%) for social isolation. Of note, institution-wide benchmark total noncompletion rates were 0.3%, 0.3%, 47%, and 39% for these respective domains. Conclusion . High total noncompletion rates make social determinants of health data challenging to interpret and underscore the need for evidence-based guidelines on how best to capture such data in underserved patients.

Are Social Media Interventions for Health Behavior Change Efficacious among Populations with Health Disparities?: A Meta-Analytic Review

While prior reviews have identified positive effects of social media interventions for health behavior change generally, it is unclear whether these effects persist in traditionally underrepresented populations that are at disproportionate risk of disease. The current meta-analysis examined the effectiveness of social media interventions for health behavior change among populations with health disparities. We analyzed 17 studies with a cumulative N = 3,561. Social media interventions had a significant moderate-sized effect on behavior change among populations with health disparities (d = 0.303, 95% CI: 0.156, 0.460, p < .001), and there was significant heterogeneity across the studies (Q = 64.48, p < .001, I2 = 75.19). Exploratory moderator analyses revealed larger effects in studies with smaller sample size (p < .05) and those using additional intervention channels, including e-mail and telephone (p < .05). Findings suggest that social media interventions may be a promising intervention tool for stimulating behavior change among populations with health disparities, but several gaps remain in the literature. Public health professionals and other health communicators should further explore ways to increase both the reach and impact of social media interventions among populations with health disparities.

Weight gain promotes the progression of IgA nephropathy in Asians: A protocol for systematic review and meta-analysis

INTRODUCTION

The relationship between weight gain and progression of IgA nephropathy (IgAN) has been investigated by many researchers but remains controversial. The incidence of IgAN is significantly higher in Asia than in other regions. Therefore, we investigated the relationship between weight gain and primary IgAN in the Asian population.

METHODS AND ANALYSIS

Seven databases were retrieved up to now. We stratified the included population by body mass index (BMI) and performed a meta-analysis of associated risk factors.

OBJECTIVES

In this study, Asian IgAN patients with different BMI were grouped together to clarify the relationship between BMI and IgAN progression in Asian populations, so as to provide more ideas and treatment means for the prevention and treatment of IgAN in the future.

COVID-19 anti-Asian racism and race-based stress: A phenomenological qualitative media analysis

OBJECTIVE

News media has recently been replete with stories of anti-Asian rhetoric and racism related to the COVID-19 pandemic. Empirical literature, however, has yet to systematically analyze and document these experiences and their impact. Our study aimed to examine this phenomenon by analyzing news media coverage published between December 31, 2019-June 30, 2020 on COVID-related anti-Asian incidents.

METHOD

We utilized a phenomenological approach to conduct qualitative content analysis of 84 media articles reporting on coronavirus related anti-Asian incidents. We also present the emerging psychological framework of race-based stress and trauma to conceptualize the psychological impact of these race-based incidents reported in the media.

RESULTS

Qualitative analysis revealed five primary themes: (a) pathologizing cultural practices; (b) alien in one's own land; (c) invalidation of interethnic differences; (d) ascription of diseased status; and (e) duality of frontline hero and virus carrier. We provide examples for each of these themes.

CONCLUSION

These themes document stigmatizing narratives and demonstrate the phenomenology of race-based stress and trauma experienced by Asian individuals during the COVID era. We present potential implications for mental health of Asian individuals during and following the COVID-19 pandemic, as well as recommendations for future research.

Serum neurofilament light chain levels are correlated with the infarct volume in patients with acute ischemic stroke

Neurofilament light chains (NfLs) are promising biomarkers of neuroaxonal damage in stroke patients. We investigated the correlations between NfL levels and infarct volume, initial stroke severity, and functional outcomes at discharge in patients with acute ischemic stroke. We prospectively included 15 patients with first-ever acute ischemic stroke and 8 age- and sex-matched healthy controls without other neurological disorders. Serum NfL levels were measured using the single-molecule array (Simoa) technique twice within 24 hours of admission (NfL1D) and on the seventh hospital day (NfL7D) in patients with stroke and once in healthy controls. We assessed the infarct volume on diffusion-weighted magnetic resonance imaging using the free software ITK-SNAP. Serum NfL1D levels in stroke patients were significantly higher (28.4 pg/mL; interquartile range [IQR], 43.0) than in healthy controls (14.5 pg/mL; IQR, 3.2; P = .005). Temporal pattern analyses demonstrated that NfL7D levels were increased (114.0 pg/mL; IQR, 109.6) compared to NfL1D levels in all stroke patients (P = .001). There was a strong correlation between NfL7D levels and infarct volume (R = 0.67, P = .007). The difference between NfL1D and NfL7D (NfLdiff levels) was strongly correlated with the infarct volume (R = 0.63; P = .013). However, there was no statistically significant correlation between NfL levels and the initial stroke severity or functional outcomes at discharge. NfL levels in the subacute stage of stroke and the NfL difference between admission and 7th day of hospital were correlated with infarct volume in patients with acute ischemic stroke.

Effectiveness of Montessori-based activities on agitation among Asian patients with dementia: A systematic review and meta-analysis

OBJECTIVES

Montessori based activity are supposed to be an effective nonpharmacological intervention in the treatment of agitation in western countries. However, most studies conducted to evaluate the effectiveness of Montessori based activities on agitation in Asian patients were small sample size, as well as inconsistent outcomes, which may limit the reliability of the conclusions. The present pooled analysis, hence, was conducted to evaluate the effectiveness of the activity on agitation related with dementia in Asian patients with dementia.

DESIGN

Prospective randomized clinical studies were included, of which available data was extracted. Outcomes of physical aggressive behaviors, physical nonaggressive behaviors, and verbal aggressive behaviors were pooled for the analysis by weighted mean differences.

DATA SOURCES

Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), WanFang, and China Science and Technology Journal Database (VIP).

ELIGIBILITY CRITERIA

Prospective, randomized, controlled clinical studies, conducted to evaluate the effectiveness of the activity on agitation related with dementia in Asian patients with dementia.

DATA EXTRACTION AND SYNTHESIS

Available data including baseline characteristics and interested outcomes from the included literature were extracted independently by 2 investigators. Measuring scales including CMAI and NOSIE were adopted for the efficacy comparison between Montessori based activity and standard activity. Weighted mean difference was used for the pooled analysis.

RESULTS

A total of 460 participants were included in the present meta-analysis. The pooled mean difference agitation for Montessori based activity was -3.86 (95% CI: -7.38 to -0.34, P = 0.03) comparing to standard activity. The pooled mean differences for physical aggressive behaviors, physical nonaggressive behaviors, and verbal aggressive behaviors in Montessori based activity group were -0.82 (95% CI: -1.10 to -0.55; P < 0.00001), -0.81 (95% CI: -1.68 to 0.55; P = 0.07), and 0.38 (95% CI: -0.92 to 1.68; P = 0.57).

CONCLUSIONS

Montessori based activities may reduce the frequency of agitation, especially in physical aggressive behaviors comparing to standard activities in Asian patients with dementia. However, the effectiveness of Montessori based activities on reduction of subcategorized agitated behaviors including physical nonaggressive behaviors, and verbal aggressive behaviors may not be reliable as physical aggressive behaviors.

Feeding difficulties in Asian children with autism spectrum disorder

BACKGROUND

To characterize the nature and severity of feeding difficulties in Asian young children with Autism Spectrum Disorders (ASD) and identify potential predictors of poorer feeding outcomes.

METHODS

Cross sectional study of children aged 1-7 years with ASD. Parents completed the following: demographic information, brief autism mealtime behavior inventory, aberrant behavior checklist (ABC), behavioral pediatrics feeding assessment scale (BPFAS) and caregiver feeding style questionnaire. Additional information (medical data, cognitive and developmental assessment results, e.g., Autism Diagnostic Observation Schedule Second Edition, Autism Diagnostic Interview, Revised, Vineland Adaptive Behaviour Scales, etc.) were subsequently obtained from electronic medical records retrospectively by one of the study team members.

RESULTS

Of the 67 children, 28.4% had feeding difficulties (high BPFAS total frequency score). Caregiver feeding styles were authoritarian (34.8%) or indulgent (39.4%). Child characteristics did not significantly predict for the severity of feeding difficulties. Univariate analysis revealed that authoritarian feeding style (p = 0.001) and ABC hyperactivity score (p = 0.006) were significantly associated with BPFAS severity score. Multivariate analysis revealed that ABC hyperactivity score remained significantly associated with BPFAS severity score after controlling for all other ABC subscale scores. A final regression model including all child characteristics and ABC scores did not reveal any significant predictors of BPFAS total frequency score (R2 = 0.557).

CONCLUSION

Our findings suggest an association between hyperactivity, authoritarian feeding style and feeding difficulties. Children with ASD who have significant hyperactivity behaviors in the context of parents with an authoritarian feeding style should be actively screened for problematic feeding behaviors.

Communication Among Southeast Asian Mothers and Daughters About Cervical Cancer Prevention

BACKGROUND

Southeast Asian women have high rates of cervical cancer and yet are among the least likely to be screened. There is sparse literature on communication patterns among Southeast Asian women, specifically related to cervical cancer and Pap test uptake. Little is known about the influence of Southeast Asian mothers and daughters on each other's cervical cancer beliefs and screening behaviors.

OBJECTIVES

We examined the perceptions of and barriers to cervical cancer screening among Cambodian and Lao mothers and daughters and explored how they converse about women's health issues, specifically cervical cancer and Pap testing.

METHODS

We conducted in-depth interviews with Cambodian and Lao mother-daughter dyads, aged 18 years and older, living in a large Midwestern city between February and September of 2015. Descriptive statistics were calculated to summarize the sample demographic characteristics. Bivariate tests (contingency table analyses, independent t-tests, and Pearson correlations) were conducted to test for differences between the mothers and daughters in demographic characteristics and measures of health status and beliefs. Qualitative data were analyzed using content analysis.

RESULTS

In-depth interviews were conducted with three Cambodian and eight Lao mother-daughter dyads. The daughters were significantly more acculturated to English, had greater education, and were mostly employed full time. The mothers and daughters evaluated their health status much the same, their medical mistrust equally, and all of the mothers and nine of the daughters were Buddhist. Themes in mother-daughter communication included what mothers and daughters do and do not talk about with regard to sexual health, refugee experiences, what hinders mother-daughter communication, and relationship dynamics. The mothers were embarrassed and uncomfortable discussing cervical cancer, Pap testing, and other women's health issues with their daughters. Although mothers did not influence women's health promotion or cervical cancer prevention with their daughters, daughters did influence their mothers' health and healthcare decisions. Daughters were critical in navigating healthcare systems, engaging with providers, and making medical decisions on behalf of their mothers.

DISCUSSION

By leveraging the unique and dynamic intergenerational bond that mothers and daughters who identify as Southeast Asian have, we can develop strategies to influence the cultural dialogue related to cervical cancer and early detection.

Cancer Mortality Disparities among Asian American and Native Hawaiian/Pacific Islander Populations in California

BACKGROUND

Asian American and Native Hawaiian/Pacific Islanders (AANHPI) are the fastest growing minority in the United States. Cancer is the leading cause of death for AANHPIs, despite relatively lower cancer morbidity and mortality. Their recent demographic growth facilitates a detailed identification of AANHPI populations with higher cancer risk.

METHODS

Age-adjusted, sex-stratified, site-specific cancer mortality rates from California for 2012 to 2017 were computed for AANHPI groups: Chinese, Filipino, South Asian, Vietnamese, Korean, Japanese, Southeast Asian (i.e., Cambodian, Hmong, Laotian, Thai), and Native Hawaiian and Other Pacific Islander (NHOPI). Regression-derived mortality rate ratios (MRR) were used to compare each AANHPI group to non-Hispanic whites (NHW).

RESULTS

AANHPI men and women (total 40,740 deaths) had lower all-sites-combined cancer mortality rates (128.3 and 92.4 per 100,000, respectively) than NHWs (185.3 and 140.6) but higher mortality for nasopharynx, stomach, and liver cancers. Among AANHPIs, both NHOPIs and Southeast Asians had the highest overall rates including for colorectal, lung (men only), and cervical cancers; South Asians had the lowest. NHOPI women had 41% higher overall mortality than NHWs (MRR = 1.41; 95% CI, 1.25-1.58), including for breast (MRR = 1.33; 95% CI, 1.08-1.65) and markedly higher for endometrial cancer (MRR = 3.34; 95% CI, 2.53-4.42).

CONCLUSIONS

AANHPI populations present with considerable heterogeneous cancer mortality patterns. Heightened mortality for infection, obesity, and tobacco-related cancers in Southeast Asians and NHOPI populations highlight the need for differentiated priorities and public health interventions among specific AANHPI populations.

IMPACT

Not all AANHPIs have favorable cancer profiles. It is imperative to expand the focus on the currently understudied populations that bear a disproportionate cancer burden.

Overcoming constraints of the model minority stereotype to advance Asian American health

Asian Americans are the fastest growing U.S. immigrant group, projected to become the largest immigrant group by 2065, but the quantity of research on Asian Americans' health has not mirrored changing demographics. Asian Americans have been understudied for more than 25 years, with only 0.17% of National Institutes of Health (NIH) expenditures allocated to projects including Asian American, Native Hawaiian, and Pacific Islander populations (Ðoàn et al., 2019). This disproportionality may result in part from the model minority stereotype (MMS) being extended to health, perpetuating the ideas that Asian Americans are well-positioned with regard to health status and that associated research is not essential. Accordingly, the aims for this article are threefold: (a) bring attention to the inadequate representation of the Asian American population in health-related science, (b) question the MMS in health, and (c) outline potential pathways through which the MMS limits what is knowable on Asian American health issues and needs. We discuss the limited meaningfulness of nonrepresentative aggregated statistics purporting the model minority image and provide counterexamples. We also present a stereotype-constraints model with the MMS contributing to a bottleneck for Asian American health-related knowledge, accompanied by present-day circumstances (e.g., sparse data, few psychologists/behavioral medicine scientists focused on Asian American health). We conclude with initial recommendations for addressing MMS-associated constraints in psychology and more broadly. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Morphologic Features of the Distal Femur and Proximal Tibia: A Cross-Sectional Study

Background

The asymmetric medial and lateral condyles of the distal femur and proximal tibia have a direct influence on the biomechanics of knee joint and prostheses design. This study aimed to determine the morphologic data, that is., anteroposterior (AP) and mediolateral (ML) widths, and the radius of curvature (ROC) of the geometric arcs of the distal femur and proximal tibia.

Methods

One hundred and seventeen adult dry bones (57 femurs and 60 tibias) were studied. Aspect ratios (AP/ML) were calculated. The AP and ML widths were measured using digital Vernier Caliper with a measuring range of 0-150 mm, resolution of 0.01 mm, and accuracy ± 0.02 mm. The geometric arcs of femoral and tibial condyles were divided into three parts namely anterior 1/3rd, distal (femur) or middle (tibia) 1/3rd and posterior 1/3rd and were estimated in the sagittal plane for the femur and transverse plane for tibia using the ROC gauges.

Results

For the femur, the mean AP length for medial and lateral condyles was 55.62 mm and 57.93 mm, respectively, while the mean ML width was 73.45 mm. For the tibia, the mean AP length for medial condyle (MC) and lateral condyle (LC) was 47.74 mm and 43.46 mm, respectively. The mean aspect ratios for the distal femur and proximal tibia were 1.26 and 1.45, respectively. The mean aspect ratios for MC and LC of the femur were 0.50 and 0.52, respectively, whereas, for tibia, they were 0.61 and 0.71, respectively. The mean ROC for femoral MC - 20.77 mm, 31.42 mm, and 19.68 mm and for LC - 21.48 mm, 64.40 mm and 19.06 mm for the anterior, distal and posterior arcs, respectively. The mean ROC for tibial MC - 22.42 mm, 22.49 mm and 19.94 mm, and LC - 19.92 mm, 21.79 mm and 20.95 mm for the anterior, middle and posterior arcs, respectively.

Conclusions

The morphologic data accumulated in this study for both the distal femur as well as the proximal tibia would provide guidelines and help the manufacturers of joint prostheses to address the potential for compromised implant fit and re-design and make available ‘anatomic’ knee prostheses appropriate for the local population which would not only improve function but also prolong the longevity of the prostheses.

Clinical Characteristics of Sarcoidosis in Asian Population: A 14-year Single Center Retrospective Cohort Study from Thailand

Background:

Little is known about epidemiology and clinical characteristics of sarcoidosis in Asian population.

Objectives:

This study aimed to examine the epidemiology and clinical characteristics of Thai patients with sarcoidosis, using databases of a tertiary care medical center.

Methods:

Potential cases of sarcoidosis were identified from two sources, the medical record-linkage system and the pathology database of Siriraj Hospital, Mahidol University in Bangkok, Thailand. Patients with ICD-10-CM codes for sarcoidosis were identified and retrieved from the medical record-linkage system from 2005 to 2018. Patients with histopathology positive for non-caseating granuloma were identified and retrieved from the pathology database from the same time period. All potential cases underwent individual medical record review to confirm the diagnosis of sarcoidosis which required compatible clinical pictures supported by presence of non-caseating granuloma, radiographic evidence of intrathoracic sarcoidosis and exclusion of other granulomatous diseases.

Results:

From 2005 to 2018, 89 confirmed cases of sarcoidosis were identified. 80.9% of them were female and mean age at diagnosis was 46.8 years (standard deviation (SD) 13.9 years). The majority of patients had intrathoracic disease (81 cases; 91.0%) but less than half had respiratory symptoms (34 cases; 41.9%). Extrathoracic disease was common in this cohort that pulmonary sarcoidosis was accompanied by extrathoracic involvement in 53 patients (65.4%). Sarcoid uveitis was the most common extrathoracic disease (35 cases; 39.3%), followed by cutaneous sarcoidosis (24 cases; 26.9%), extrathoracic lymphadenopathy (18 cases; 22.5%) and sarcoid arthropathy (4 cases; 4.5%).

Conclusion:

The current study examined clinical characteristics of sarcoidosis in an Asian population and found high prevalence of uveitis and marked female predominance. (Sarcoidosis Vasc Diffuse Lung Dis 2020; 37 (4): e2020011)

Further Reduction in Help-Seeking Behaviors Amidst Additional Barriers to Mental Health Treatment in Asian Populations: A Contemporary Review

Under diagnosis and treatment of mental health illnesses lead to chronic presentations and consequences. Multiple factors contribute to gaps in treatment, including the role culture plays in the development or suppression of help-seeking behaviors (HSBs). In the Asian community, conversation and recognition of mental health and its disorders are considered shameful. This review presents an analysis of literature to identify barriers to mental health treatment pronounced in Asian populations and discusses how culture influences these barriers and treatment-seeking behaviors, particularly in the context of the Asian-origin Coronavirus disease 2019 (COVID-19) global pandemic. It is the purpose of this review to discuss Asian American underutilization of mental health services and understand the factors the contribute to psychiatric care resistance in Asian communities.

5HTTLPR polymorphism and postpartum depression risk: A meta-analysis

OBJECTIVE

Postpartum depression (PPD) is an episode of major depressive disorder that affecting women of childbearing age. 5-HTTLPR is 1 of the most extensively investigated polymorphisms in PPD. However, the previous results were inconsistent and inclusive. Hence, we performed a meta-analysis to precisely evaluate the association between 5-HTTLPR polymorphism and PPD susceptibility.

METHODS

The studies were retrieved through databases including PubMed, web of science, EMASE, and CNKI. The odd ratios (ORs) and 95% confidence interval (CIs) were applied for evaluating the genetic association between 5-HTTLPR (L/S) polymorphism and PPD risk.

RESULTS

Six studies with 519 cases and 737 controls were enrolled in the present study. The frequencies of allelic (OR = 0.72, 95%CI = 0.60-0.85, P = .0001) and dominant (OR = 0.57, 95%CI = 0.44-0.73, P = .004) models of 5-HTTLPR polymorphism significantly decreased in patients with PPD than those in the healthy controls. Subgroup analysis based on ethnicity revealed that the allelic (OR = 0.71, 95%CI = 0.60-0.85, P = .0001) and dominant (OR = 0.51, 95%CI = 0.32-0.79, P = .003) models of 5-HTTLPR polymorphism were significantly associated with PPD risk in Asian population (P > .05). No evidence was observed between the recessive model of 5-HTTLPR polymorphism and PPD risk (P > .05).

CONCLUSIONS

The allelic and dominant models of 5-HTTLPR polymorphism might be protective factors for PPD. To confirm these results, larger number of association studies or multicenter case-control studies are necessary in the future.

Thyroid Eye Disease-Related Epiblepharon: A Comparative Case Study

PURPOSE

This study describes the clinical features and management of epiblepharon as a manifestation of thyroid eye disease (TED). In addition, we compare the frequency and age in Asian and non-Asian patients, and discuss pathophysiologic implications.

DESIGN

Retrospective case-control study.

METHODS

This is a single-center retrospective review that identified 172 adult patients (age 19 to 83) with TED that were consecutively evaluated by 1 author (T.J.M.) between December 2015 and July 2018. Diagnosis of TED and epiblepharon was based upon clinical assessment as documented in the medical record.

RESULTS

In a cohort of 172 patients (mean age 52; 138 female), 3 patients with acquired epiblepharon were identified, all of whom were Asian. The proportion of affected Asian patients (3/of 17, 17.6%) was significantly higher than that of non-Asian patients (0/155, P < 0.001). Patients with epiblepharon were also significantly younger than those without epiblepharon, 29.7 ± 2.1 versus 48.7 ± 13 years of age (P = 0.026). All 3 patients underwent surgical correction with lateral canthoplasty and anterior lamellar pretarsal fixation with successful outcomes.

CONCLUSIONS

Lower eyelid epiblepharon may occur in TED. In our clinic-based population, this finding was significantly more frequent in Asian patients and in younger patients. Relieving horizontal tension in conjunction with anterior lamella pretarsal fixation is an effective method of correcting TED-associated epiblepharon.

Efficacy and safety assessment of S-1-based regimens comparing to intravenous fluorouracil-based ones in Asian patients with metastatic colorectal carcinoma: A system review and meta-analysis

BACKGROUND

We performed the present systematic review and meta-analysis to evaluate the efficacy and safety for S-1-based regimens comparing to intravenous fluorouracil-based ones in Asian patients with metastatic colorectal carcinoma (mCRC).

METHODS

Eligible prospective and controlled randomized clinical trials (RCT) were included, of which data were extracted by inclusion criteria and exclusion ones. Odds ratio (OR) and Hazard ratio (HR) of outcomes including objective response rate (ORR), disease control rate (DCR), progressive-free survival (PFS), overall survival (OS), and adverse events (AEs) were explored for the final analysis between the 2 groups.

RESULTS

A total of 23 eligible prospective, controlled RCTs including 2269 patients were enrolled for the pooled analysis. With the meta-analysis of available data, the results of the present research showed that there was no statistical difference on short-term efficacy including ORR (HR = 0.85, 95% CI: 0.71-1.01; P = .07) or DCR (HR = 0.88, 95% CI: 0.69-1.11; P = .27), as well as long-term efficacy including PFS (HR = 1.00, 95% CI: 0.90-1.11; P = .98) or OS (HR = 0.95, 95% CI: 0.82-1.10; P = .50). In addition, the incidences of AEs including leucopenia, neutropenia, and vomiting were statistically lower in S-1-based regimens comparing to intravenous fluorouracil-based ones, regardless of all grade or high grade (all P <.05). However, there were no significant differences detected among other AEs including anemia, thrombocytopenia, increased alanine aminotransferase concentration, stomatitis, anorexia, diarrhea, hand-foot syndrome (HFS), or sensory neuropathy among the 2 groups (all P >.05).

CONCLUSIONS

The present meta-analysis revealed that S-1-based regimens might be associated with comparable efficacy, as well as lower risk of leucopenia, neutropenia, and vomiting at all/high grade comparing to intravenous fluorouracil-based ones in Asian patients with mCRC.

Associations of Race and Ethnicity With Patient-Reported Outcomes and Health Care Utilization Among Older Adults Initiating a New Episode of Care for Back Pain

STUDY DESIGN

Secondary analysis of the Back Pain Outcomes using Longitudinal Data (BOLD) cohort study.

OBJECTIVE

To characterize associations of self-reported race/ethnicity with back pain (BP) patient-reported outcomes (PROs) and health care utilization among older adults with a new episode of care for BP.

SUMMARY OF BACKGROUND DATA

No prior longitudinal studies have characterized associations between multiple race/ethnicity groups, and BP-related PROs and health care utilization in the United States.

METHODS

This study included 5117 participants ≥65 years from three US health care systems. The primary BP-related PROs were BP intensity and back-related functional limitations over 24 months. Health care utilization measures included common diagnostic tests and treatments related to BP (spine imaging, spine-related relative value units [RVUs], and total RVUs) over 24 months. Analyses were adjusted for multiple potential confounders including sociodemographics, clinical characteristics, and study site.

RESULTS

Baseline BP ratings were significantly higher for blacks vs. whites (5.8 vs. 5.0; P < 0.001). Participants in all race/ethnicity groups showed statistically significant, but modest improvements in BP over 24 months. Blacks and Hispanics did not have statistically significant improvement in BP-related functional limitations over time, unlike whites, Asians, and non-Hispanics; however, the magnitude of differences in improvement between groups was small. Blacks had less spine-related health care utilization over 24 months than whites (spine-related RVU ratio of means 0.66, 95% confidence interval [CI] 0.51-0.86). Hispanics had less spine-related health care utilization than non-Hispanics (spine-related RVU ratio of means 0.60; 95% CI 0.40-0.90).

CONCLUSION

Blacks and Hispanics had slightly less improvement in BP-related functional limitations over time, and less spine-related health care utilization, as compared to whites and non-Hispanics, respectively. Residual confounding may explain some of the association between race/ethnicity and health outcomes. Further studies are needed to understand the factors underlying these differences and which differences reflect disparities.

Racial-ethnic microaggressions, coping strategies, and mental health in Asian American and Latinx American college students: A mediation model

The current study examined the link between racial-ethnic microaggressions and psychological distress among 308 Asian American (n = 164) and Latinx American (n = 144) college students (54% female). Additionally, coping strategies (engagement and disengagement) were examined as potential mediators in this link. A confirmatory factor analysis (CFA) of the Racial-Ethnic Microaggressions Scale (REMS) was conducted to test the factor structure with an Asian American and Latinx American emerging adult population (Ages 18-26). A multigroup path analysis of the analytic model was then performed to examine the hypothesized relations between racial-ethnic microaggressions, coping strategies, and psychological distress among Asian American and Latinx American participants. Results of the CFA did not support the original 6-factor structure of the REMS in this sample. However, a 1-factor structure (i.e., total scale score) indicated good fit. Findings from the path analysis indicated that among the total sample, racial-ethnic microaggressions were directly linked to increased psychological distress. Furthermore, engagement coping strategies partially mediated this relationship and were linked to less psychological distress. (PsycINFO Database Record

Inherited mutations in BRCA1 and BRCA2 in an unselected multiethnic cohort of Asian patients with breast cancer and healthy controls from Malaysia

BACKGROUND

Genetic testing for BRCA1 and BRCA2 is offered typically to selected women based on age of onset and family history of cancer. However, current internationally accepted genetic testing referral guidelines are built mostly on data from cancer genetics clinics in women of European descent. To evaluate the appropriateness of such guidelines in Asians, we have determined the prevalence of germ line variants in an unselected cohort of Asian patients with breast cancer and healthy controls.

METHODS

Germ line DNA from a hospital-based study of 2575 unselected patients with breast cancer and 2809 healthy controls were subjected to amplicon-based targeted sequencing of exonic and proximal splice site junction regions of BRCA1 and BRCA2 using the Fluidigm Access Array system, with sequencing conducted on a Illumina HiSeq2500 platform. Variant calling was performed with GATK UnifiedGenotyper and were validated by Sanger sequencing.

RESULTS

Fifty-five (2.1%) BRCA1 and 66 (2.6%) BRCA2 deleterious mutations were identified among patients with breast cancer and five (0.18%) BRCA1 and six (0.21%) BRCA2 mutations among controls. One thousand one hundred and eighty-six (46%) patients and 97 (80%) carriers fulfilled the National Comprehensive Cancer Network guidelines for genetic testing.

CONCLUSION

Five per cent of unselected Asian patients with breast cancer carry deleterious variants in BRCA1 or BRCA2. While current referral guidelines identified the majority of carriers, one in two patients would be referred for genetic services. Given that such services are largely unavailable in majority of low-resource settings in Asia, our study highlights the need for more efficient guidelines to identify at-risk individuals in Asia.

Evaluation of the relative effectiveness of the 2017 updated Manchester scoring system for predicting BRCA1/2 mutations in a Southeast Asian country

BACKGROUND

Germline mutations in the BRCA1 and BRCA2 genes have significant clinical implications for both risk-reducing and early surveillance management. The third and most recent revision of the Manchester scoring system (MSS3) used to distinguish patients indicated for germline BRCA1/2 testing included further adjustments for triple negative breast cancer, high-grade serous ovarian cancer and human epidermal growth factor 2 (HER2) receptor status. This study aims to evaluate the relative effectiveness of MSS3 in a Southeast Asian population.

METHODS

All patients in our centre were tested using next-generation sequencing (NGS) panels that included full gene sequencing as well as coverage for large deletions/duplications in BRCA1/2. We calculated MSS1-3 scores for index patients between 2014 and 2017 who had undergone BRCA1/2 genetic testing and recorded their genetic test results. MSS1-3 outcomes were compared using receiver operating characteristic analysis, while associations with predictors were investigated using Fisher's exact test and logistics regression. Calculations were performed using Medcalc17.

RESULTS

Of the 330 included patients, 47 (14.2%) were found to have a germline mutation in BRCA1 or BRCA2. A positive HER2 receptor was associated with a lower likelihood of a BRCA1/2mutation (OR=0.125, 95% CI 0.016 to 0.955; P=0.007), while high-grade serous ovarian cancer was conversely associated with an increased likelihood of a BRCA1/2 mutation (OR=5.128, 95% CI 1.431 to 18.370; P=0.012). At the 10% threshold, 43.0% (142/330) of patients were indicated for testing under MSS3, compared with 35.8% (118/330) for MSS1% and 36.4% (120/330) for MSS2. At the 10% threshold, MSS3 sensitivity was 91.5% and specificity 65.0%, significantly better than the previous MSS1 (P=0.037) and MSS2 (P=0.032) models.

CONCLUSION

Our results indicate that the updated MSS3 outperforms previous iterations and relative to the Manchester population, is just as effective in identifying patients with BRCA1/2 mutations in a Southeast Asian population.

Asian Adolescents with Excess Weight are at Higher Risk for Insulin Resistance than Non-Asian Peers

OBJECTIVE

The purpose of this study was to evaluate whether Asian American adolescents have higher metabolic risk from excess weight than non-Asians.

METHODS

Seven hundred thirty-three students, aged 14 to 19 years old, completed a school-based health screening. The 427 Asian and 306 non-Asian students were overall equivalent on age, sex, and family income. Height, weight, waist circumference, percent body fat, and blood pressure were measured. Fasting triglycerides, high- and low-density lipoproteins, glucose, and insulin levels were measured. Asian and non-Asians in lean or overweight/obesity groups were contrasted on the five factors that make up the metabolic syndrome.

RESULTS

Asian adolescents carrying excess weight had significantly higher insulin resistance (IR), triglyceride levels, and waist-height ratios (W/H), despite a significantly lower overall BMI than corresponding non-Asians. Similarly, Asians had a stronger relationship between W/H and the degree of IR than non-Asian counterparts; 35% and 18% of the variances were explained (R² = 0.35, R² = 0.18) respectively, resulting in a significant W/H by racial group interaction (F_change [1,236] = 11.56, P < 0.01).

CONCLUSIONS

Despite lower overall BMI, Asians have higher IR and triglyceride levels from excess weight than their non-Asian counterparts. One-size-fits-all public health policies targeting youth should be reconsidered and attention paid to Asian adolescents, including those with mild degrees of excess weight.

Impact of obesity on the short-term outcomes of single-port laparoscopic colectomy for colorectal cancer in the Asian population: A retrospective cohort study

Single-port laparoscopic surgery (SPLS) is being increasingly performed for treating colorectal cancer. Here, we aimed to assess the safety and feasibility of SPLS for colorectal cancer in obese patients through a comparison of their short-term outcomes with those of nonobese patients.A total of 323 patients who underwent SPLS for colorectal cancer at our center between March 2009 and August 2014 were enrolled. The outcomes were analyzed according to the body mass index (BMI) category: nonobese (BMI < 25), obese I (BMI: 25.0-29.9), and obese II (BMI ≥ 30).Of the 323 patients, 233 (72.1%), 80 (24.8%), and 10 (3.1%), were assigned to the nonobese, obese I, and obese II groups, respectively. The clinicopathologic patient characteristics, such as age, gender, tumor location, and previous laparotomy, were similar among the 3 groups. The mean operative time (nonobese vs obese I vs and obese II groups: 269.2 vs 270.4 vs 342.8 minutes, respectively) and estimated surgical blood loss (277.7 vs 260.5 vs 387.0 mL, respectively) were greater in the obese II group than in the nonobese and obese I groups, although the difference was not significant (P = .247 and P = .205, respectively). However, the time to passage of flatus significantly differed among the groups (P = .040); in particular, this value was significantly longer in the obese II group than in the obese I group (P = .031). None of the other parameters, including conversion to open or conventional laparoscopic surgery and intra- and postoperative morbidity, significantly differed among the 3 groups.SPLS for colorectal cancer can be safely performed in obese Asian patients with equivalent short-term outcomes as compared with that in nonobese patients. Hence, SPLS can be safely recommended for colorectal cancer in obese patients if the surgeon is experienced. Nevertheless, the technique used warrants further investigation, and a large-scale prospective study is required.

Pleural LDH as a prognostic marker in adenocarcinoma lung with malignant pleural effusion

To study the performance of serum and pleural lactate dehydrogenase (LDH) level in predicting survival in patients with adenocarcinoma lung presenting with malignant pleural effusions (MPE) at initial diagnosis.Retrospective cohort study of the patient hospitalized for adenocarcinoma lung with MPE in year 2012.Univariate analyses showed lower pleural fluid LDH 667 (313-967) versus 971 (214-3800), P = 0.04, female gender 9 (100%) versus 27 (41.5%), P = 0.009, never smoking status 9 (100%) versus 36 (55.3%), P = 0.009, and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy 8 (89%) versus 26 (40%), P = 0.009 to correlate with survival of more than 1.7 year versus less than 1.7 year. In multivariate analysis, low pleural fluid LDH and female gender maintained significance. The pleural LDH level of ≤1500 and >1500 U/L discriminated significantly (P = 0.009) between survival.High pleural LDH (>1500 IU/L) predicts shorter survival (less than a year) in patients with adenocarcinoma lung presenting with MPE at the time of initial diagnosis. This marker may be clinically applied for selecting therapeutic modality directed at prevention of reaccumulation of MPE. Patients with low pleural LDH may be considered suitable for measures that provide more sustained effect on prevention of reaccumulation such as chemical pleurodesis or tunneled pleural catheter.

Montelukast Use and Patterns of Ambulatory Care among Asian versus Non-Asian Adult Patients with Asthma and/or Allergic Rhinitis in the United States

Background: Asthma and allergic rhinitis (AR) are inflammatory conditions that are similar in pathophysiology. Mild-to-moderate persistent asthma has been widely treated with inhaled corticosteroids, while allergic rhinitis is commonly treated with antihistamines, nasal corticosteroids, anticholinergics, and other allergy specific medications. The introduction of montelukast, a leukotriene receptor antagonist, has opened a treatment pathway that is common to both conditions. Previous real world studies of montelukast (Singulair®) relative to other medications have not investigated the role of race in the management of asthma and AR, specifically as relates to differences among Asian versus non-Asian patients. Objective: To contrast montelukast use and patterns of ambulatory care for adult Asian versus non-Asian patients in the United States with asthma and/or AR. Methods: Data for adult asthma and AR patients were extracted from a national electronic medical records database for the years 2006-2014. Patients were classified into condition cohort (Asthma-Only, AR-Only, Asthma & AR), and treatment condition (monotherapy or combination therapy, with or without montelukast for Asthma and Asthma & AR cohorts, usual care with or without montelukast for AR-Only) and stratified by race (Asian vs. non-Asian). Results: Overall patterns of use of montelukast were similar for Asian and non-Asian patients, but Asians were more likely to receive it as part of a combination therapy regimen. Changes in treatment regimen followed similar patterns for both groups. Asian patients with both asthma and AR were found to have lower service utilization rates if their therapy included montelukast, whereas for non-Asians there was no significant difference between regimens with or without montelukast. Conclusion: Differences in montelukast use and outcomes of care exist between Asian and non-Asian patients in the United States. Future research should explore the reasons for these differences and whether they can be replicated in non-US settings.

Ethnicity moderates the outcomes of self-enhancement and self-improvement themes in expressive writing

The current study examined whether writing content related to self-enhancing (viz., downward social comparison and situational attributions) and self-improving (viz., upward social comparison and persistence) motivations were differentially related to expressive writing outcomes among 17 Asian American and 17 European American participants. Content analysis of the essays revealed no significant cultural group differences in the likelihood of engaging in self-enhancing versus self-improving reflections on negative personal experiences. However, cultural group differences were apparent in the relation between self-motivation processes and changes in anxiety and depressive symptoms at 3-month follow-up. Among European Americans, writing that reflected downward social comparison predicted positive outcomes, whereas persistence writing themes were related to poorer outcomes. For Asian Americans, writing about persistence was related to positive outcomes, whereas downward social comparison and situational attributions predicted poorer outcomes. Findings provide evidence suggesting culturally distinct mechanisms for the effects of expressive disclosure. (PsycINFO Database Record

Growth of Indonesian Infants Compared With World Health Organization Growth Standards

OBJECTIVES

The ability of the World Health Organization (WHO) growth standards to represent the growth of South East Asian infants has been questioned. The aim of this study was to provide contemporary data on the growth of Indonesian breast-fed and formula-fed infants, compared with the WHO growth standards.

METHODS

A prospective cohort study of 160 normal healthy infants was undertaken in a suburban area of South Jakarta, Indonesia. Infants from 2 to 6 weeks of age were recruited, and they consumed exclusively either breast milk or infant formula for at least 6 months, with follow-up until 12 months of age.

RESULTS

Overall, the infants in the present study were lighter (weight-for-age), were shorter (length-for-age), and had smaller head circumferences (head circumference-for-age) than the average WHO Growth Reference Study population but were of similar proportion (weight-for-length). Compared with the WHO Growth Reference Study, the z scores for weight-for-age, length-for-age, and head circumference-for-age in the Indonesian children fell from birth to 6 weeks of age and then increased until 3 months of age in both the breast-fed and the formula-fed infants. At 6 weeks of age, the weight-for-age z scores fell below -2 standard deviations for 16 (20.5%) breast-fed and 40 (51.3%) formula-fed infants, and the length-for-age z scores fell below -2 standard deviations for 31 (39.7%) breast-fed and 41 (52.6%) formula-fed infants.

CONCLUSION

The WHO growth standards do not reflect the growth of the present cohort of Indonesian infants and may overestimate the levels of underweight and stunted children.

Lifetime risk of being diagnosed with, or dying from, prostate cancer by major ethnic group in England 2008-2010

BACKGROUND

In the UK, a man's lifetime risk of being diagnosed with prostate cancer is 1 in 8. We calculated both the lifetime risk of being diagnosed with and dying from prostate cancer by major ethnic group.

METHODS

Public Health England provided prostate cancer incidence and mortality data for England (2008-2010) by major ethnic group. Ethnicity and mortality data were incomplete, requiring various assumptions and adjustments before lifetime risk was calculated using DevCan (percent, range).

RESULTS

The lifetime risk of being diagnosed with prostate cancer is approximately 1 in 8 (13.3 %, 13.2-15.0 %) for White men, 1 in 4 (29.3 %, 23.5-37.2 %) for Black men, and 1 in 13 (7.9 %, 6.3-10.5 %) for Asian men, whereas that of dying from prostate cancer is approximately 1 in 24 (4.2 %, 4.2-4.7 %) for White men, 1 in 12 (8.7 %, 7.6-10.6 %) for Black men, and 1 in 44 (2.3 %, 1.9-3.0 %) for Asian men.

CONCLUSIONS

In England, Black men are at twice the risk of being diagnosed with, and dying from, prostate cancer compared to White men. This is an important message to communicate to Black men. White, Black, and Asian men with a prostate cancer diagnosis are all as likely to die from the disease, independent of their ethnicity. Nonetheless, proportionally more Black men are dying from prostate cancer in England.

Predictors of exclusive breastfeeding at least 8 weeks among Asian and Native Hawaiian or other Pacific Islander race subgroups in Hawaii, 2004-2008

Breastfeeding is nurturing, cost-effective, and beneficial for the health of mother and child. Babies receiving formula are sick more often and are at higher risk for childhood obesity, diabetes, asthma, and other conditions compared with breastfed children. National and international organizations recommend exclusive breastfeeding for 6 months. Exclusive breastfeeding in Asian and Native Hawaiian or Other Pacific Islander (NHOPI) subgroups is not well characterized. Data from the 2004-2008 Hawaii Pregnancy Risk Assessment Monitoring System, a population-based surveillance system on maternal behaviors and experiences before, during, and after pregnancy, were analyzed for 8,508 mothers with a recent live birth. We examined exclusive breastfeeding status for at least 8 weeks. We calculated prevalence risk ratios across maternal race groups accounting for maternal and socio-demographic characteristics. The overall estimate of exclusive breastfeeding for at least 8 weeks was 36.3%. After adjusting for maternal age, pre-pregnancy weight, cesarean delivery, return to work/school, and self-reported postpartum depressive symptoms, the racial differences in prevalence ratios for exclusive breastfeeding for each ethnic group compared to Whites were: Samoan (aPR = 0.54; 95% CI 0.43-0.69), Filipino (aPR = 0.58; 95% CI 0.53-0.63), Japanese (aPR = 0.58; 95% CI 0.52-0.65), Chinese (aPR = 0.64; 95% CI 0.58-0.70), Native Hawaiian (aPR = 0.67; 95% CI 0.61-0.72), Korean (aPR = 0.72; 95% CI 0.64-0.82), and Black (aPR = 0.79; 95% CI 0.65-0.96) compared to white mothers. Providers and community groups should be aware that just over one-third of mothers breastfeed exclusively at least 8 weeks with lower rates among Asian, NHOPI, and Black mothers. Culturally appropriate efforts to promote exclusive breastfeeding are recommended particularly among Asian subgroups that have high breastfeeding initiation rates that do not translate into high exclusivity rates.

Acculturative stress and inflammation among Chinese immigrant women

OBJECTIVE

Among Chinese immigrant populations, increasing duration of US residence is associated with elevated risk for various chronic diseases. Although life-style changes after migration have been extensively studied in immigrant populations, the psychosocial impact of acculturative stress on biological markers of health is less understood. Thus, the purpose of the present study is to examine associations between acculturative stress and inflammatory markers in a Chinese immigrant population.

METHODS

Study participants (n = 407 foreign-born Chinese American women) completed questionnaires assessing levels of stress, including acculturative stress and positive and negative life events in the previous year. Participant height and weight were measured using standard protocols, and blood samples were drawn for assessment of circulating serum levels of C-reactive protein (CRP) and soluble tumor necrosis factor receptor 2 (sTNFR2).

RESULTS

Higher levels of acculturative stress were significantly associated with higher levels of CRP (B = 0.07, 95% confidence interval = 0.01-0.13, p = .031) and sTNFR2 (B = 0.02, 95% confidence interval = 0.004-0.03, p = .012), adjusting for age and body mass index. The latter association was no longer statistically significant when overall acculturation (i.e., identification with American culture) was included in the model. Life events were not associated with CRP or sTNFR2.

CONCLUSIONS

This is one of the first studies to demonstrate that acculturative stress is associated with inflammatory markers in a Chinese immigrant population. Replication in other immigrant samples is needed to fully establish the biological correlates and clinical consequences of acculturative stress.

Spectrum of very early breast cancer in a setting without organised screening

BACKGROUND

Within a setting without organised breast cancer screening, the characteristics and survival of very early breast cancer were determined.

METHODS

All 4930 women diagnosed with breast cancer in University Malaya Medical Center, Malaysia from 1993 to 2011 were included. Factors associated with very early presentation (stage I) at diagnosis were identified. Tumour characteristics, management patterns, and survival of very early breast cancer were described, and where appropriate, compared with other settings.

RESULTS

Proportion of women presenting with stage I breast cancer significantly increased from 15.2% to 25.2% over two decades. Factors associated with very early presentation were Chinese ethnicity, positive family history of breast cancer, and recent period of diagnosis. Within stage I breast cancers, median tumour size at presentation was 1.5 cm. A majority of stage I breast cancer patients received mastectomy, which was associated with older age, Chinese ethnicity, postmenopausal status, and larger tumours. Chemotherapy was administered in 36% of patients. Five-year age-adjusted relative survival for women with stage I breast cancer was 99.1% (95% CI: 97.6-99.6%).

CONCLUSIONS

The proportion of women presenting with very early breast cancer in this setting without organised screening is increasing. These women seem to survive just as well as their counterparts from affluent settings.

Risky sexual behavior among rural female adolescents in Malaysia: a limited role of protective factors

PURPOSE

This paper presents the findings of a cross-sectional survey on the risk and protective factors of premarital sexual behavior among rural female adolescents in Peninsular Malaysia.

METHODS

We investigated data on 770 female respondents aged 13-17 years in rural areas to identify predictive factors for premarital sexual intercourse. Data were analyzed using bivariate and multivariate regression. Specific socio-demographic factors, psychological and family domains, peer delinquency, and knowledge and attitudes about sexuality were considered in risky sexual behaviors in rural Malay girls. The effects of other covariates for premarital sexual intercourse were controlled by logistic regression model.

RESULTS

Of the 770 rural female students, about 3.2% of respondents reported experience of sexual intercourse in the past three months. Out of those sexually active girls, 36% were 17 years old and 20% stated having sexual intercourse with more than one partner, and 72% did not use contraception during the most recent sexual intercourse. Midnight activities, peer-sexual disorder, self-evaluation, and attitude toward sexual health were significant predictors of sexual intercourse in rural girls in Malaysia.

CONCLUSION

The finding highlights the impact of psychological factors and peer group influences on the challenges of premarital sexual behavior among rural girls and the notion of school-based sexual health education for adolescents. This study triggers other researchers take into account a comprehensive view of protective factors operating in adolescents' risky sexual behaviors in Asian culture seeing that family domain variables, unexpectedly, exerted no predicting influence on sexually active female teens in rural areas in Malaysia.

Hyperreactivity to weak acoustic stimuli and prolonged acoustic startle latency in children with autism spectrum disorders

BACKGROUND

People with autism spectrum disorders (ASD) are known to have enhanced auditory perception, however, acoustic startle response to weak stimuli has not been well documented in this population. The objectives of this study are to evaluate the basic profile of acoustic startle response, including peak startle latency and startle magnitude to weaker stimuli, in children with ASD and typical development (TD), and to evaluate their relationship to ASD characteristics.

METHODS

We investigated acoustic startle response with weak and strong acoustic stimuli in 12 children with ASD and 28 children with TD, analyzing the relationship between startle measures and quantitative autistic traits assessed with the Social Responsiveness Scale (SRS). The electromyographic activity of the left orbicularis oculi muscle to acoustic stimuli of 65 to 115 dB sound pressure level (SPL), in increments of 5 dB, was measured to evaluate acoustic startle response. The average eyeblink magnitude for each acoustic stimuli intensity and the average peak startle latency of acoustic startle response were evaluated.

RESULTS

The magnitude of the acoustic startle response to weak stimuli (85 dB or smaller) was greater in children with ASD. The peak startle latency was also prolonged in individuals with ASD. The average magnitude of the acoustic startle response for stimulus intensities greater than 85 dB was not significantly larger in the ASD group compared with the controls. Both greater startle magnitude in response to weak stimuli (particularly at 85 dB) and prolonged peak startle latency were significantly associated with total scores, as well as several subscales of the SRS in the whole sample. We also found a significant relationship between scores on the social cognition subscale of the SRS and the average magnitude of the acoustic startle response for stimulus intensities of 80 and 85 dB in the TD group.

CONCLUSIONS

Children with ASD exhibited larger startle magnitude to weak stimuli and prolonged peak startle latency. These startle indices were related to several characteristics of ASD. A comprehensive investigation of acoustic startle response, including the magnitude of startle responses to weak stimuli and peak startle latency, might further our understanding of the neurophysiological impairments underlying ASD.

A prospective, molecular epidemiology study of EGFR mutations in Asian patients with advanced non-small-cell lung cancer of adenocarcinoma histology (PIONEER)

INTRODUCTION

PIONEER (NCT01185314) was a prospective, multinational, epidemiological study of epidermal growth factor receptor (EGFR) mutations in patients from Asia with newly diagnosed advanced lung adenocarcinoma.

METHODS

Eligible patients (aged ≥20 years) had untreated stage IIIB/IV adenocarcinoma. The EGFR mutation status (primary end point: positive, negative, or undetermined) of tumor samples (biopsy, surgical specimen, or cytology) was determined (Scorpion amplification refractory mutation system). EGFR mutation frequency was calculated and compared between demographic and clinical subgroups.

RESULTS

Of 1482 patients from seven Asian regions, 43.4% of patients were female, median age was 60 years (range, 17-94), and 52.6% of patients were never-smokers. EGFR mutation status was evaluable in tumors from 1450 patients (97.8%) (746 [51.4%] positive; 704 [48.6%] negative). Country, sex, ethnicity, smoking status, pack-years (all p < 0.001), disease stage (p = 0.009), and histology type (p = 0.016) correlated significantly with EGFR mutation frequency. Mutation frequency was 61.1% in females, 44.0% in males; lower in patients from India (22.2%) compared with other areas (47.2%-64.2%); highest among never-smokers (60.7%); and decreased as pack-year number increased (>0-10 pack-years, 57.9%; >50 pack-years, 31.4%) (similar trend by sex). Ethnic group (p < 0.001) and pack-years (p < 0.001) had statistically significant associations with mutation frequency (multivariate analysis); sex was not significant when adjusted for smoking status.

CONCLUSION

PIONEER is the first prospective study to confirm high EGFR mutation frequency (51.4% overall) in tumors from Asian patients with adenocarcinoma. The observed high mutation frequency in demographic/clinical subgroups compared with white populations suggests that mutation testing should be considered for all patients with stage IIIB/IV adenocarcinoma, even males and regular smokers, among Asian populations.

Influences of stigma and HIV transmission knowledge on member support for faith-placed HIV initiatives in Chinese immigrant Buddhist and protestant religious institutions in New York City

Ethnic religious institutions in the United States are uniquely positioned to influence HIV programming within Asian immigrant communities at large. This article examines how knowledge of HIV transmission and stigma potentially influenced attendees' support for their institutions' involvement in HIV programs. Quantitative questionnaires were individually administered to 400 Chinese attendees of Protestant churches and 402 attendees of Buddhist temples in New York City. Mediational analyses indicated that HIV stigma significantly mediated the direct effects of HIV transmission knowledge on attendees' support of their institution's involvement in HIV education (bias corrected and accelerated [BCa] 95% confidence interval [CI], 0.004 to 0.051), HIV care (BCa 95% CI, 0.019 to 0.078), and stigma reduction initiatives (BCa 95% CI, 0.013 to 0.070), while controlling for religious affiliation, age, gender, and education. To mobilize Chinese churches and temples to engage in HIV programming, it remains important to support educational programs on HIV transmission that specifically help to mitigate stigma toward persons living with HIV.

Risks for HIV and other sexually transmitted infections among Asian men who have sex with men in Vancouver, British Columbia: a cross-sectional survey

BACKGROUND

Individuals of Asian heritage represent the largest ethnic minority in Canada. Approximately 10% of the new HIV diagnoses in men in British Columbia occur among Asian-Canadians. However, the HIV risk patterns of Asian men who have sex with men (MSM) have not been extensively studied.

METHODS

Participants aged ≥ 19 years were enrolled in a venue-based HIV serobehavioural survey of MSM in Vancouver, Canada. We compared the demographic characteristics, risk behaviours, and prevalence of HIV and other sexual and blood borne infections between Asian and non-Asian MSM using bivariate analysis and logistic regression confounder modelling.

RESULTS

Amongst 1132 participants, 110 (9.7%) self-identified as Asian. Asian participants were younger than non-Asian participants (median age 29 vs. 32 years; p < 0.001), but otherwise did not differ from other study participants. HIV prevalence was lower among Asian MSM compared to Non-Asian MSM (3.7% vs 19.0%, p <0.001). Among men who self-reported as HIV negative or unknown we found no differences in unprotected anal intercourse (UAI) with a discordant or unknown serostatus partner in the previous six months (11 vs. 13%; p = 0.503). However, Asian MSM were less likely to report ever using injection drugs (10.8% vs. 19.2%; p = 0.043) or using alcohol before having sex (52% vs. 64.4%; p = 0.017).

CONCLUSIONS

Asian MSM in our study reported similar rates of UAI as non-Asian MSM, but had a lower prevalence of HIV infection. Other factors, such as the use of drugs and alcohol, in relation to sex, may partly explain these differences. However this requires further investigation.

A systematic review of overweight, obesity, and type 2 diabetes among Asian American subgroups

This systematic review synthesizes data published between 1988 and 2009 on mean BMI and prevalence of overweight, obesity, and type 2 diabetes among Asian subgroups in the U.S. We conducted systematic searches in Pub- Med for peer-reviewed, English-language citations that reported mean BMI and percent overweight, obesity, and diabetes among South Asians/Asian Indians, Chinese, Filipinos, Koreans, and Vietnamese. We identified 647 database citations and 23 additional citations from hand-searching. After screening titles, abstracts, and full-text publications, 97 citations remained. None were published between 1988 and 1992, 28 between 1993 and 2003, and 69 between 2004 and 2009. Publications were identified for the following Asian subgroups: South Asian (n=8), Asian Indian (n=20), Chinese (n=44), Filipino (n=22), Korean (n= 8), and Vietnamese (n=3). The observed sample sizes ranged from 32 to 4245 subjects with mean ages from 24 to 78 years. Among samples of men and women, the lowest reported mean BMI was in South Asians (22.1 kg/m(2)), and the highest was in Filipinos (26.8 kg/m(2)). Estimates for overweight (12.8-46.7%) and obesity (2.1-59.0%) were variable. Among men and women, the highest rate of diabetes was reported in Asian Indians with BMI ≥ 30 kg/m(2) (32.9%, age and sex standardized). This review suggests heterogeneity among U.S. Asian populations in cardiometabolic risk factors, yet comparisons are limited due to variability in study populations, methods, and definitions used in published reports. Future efforts should adopt standardized methods to understand overweight, obesity and diabetes in this growing U.S. ethnic population.

Existing maternal obesity guidelines may increase inequalities between ethnic groups: a national epidemiological study of 502,474 births in England

BACKGROUND

Asians are at increased risk of morbidity at a lower body mass index (BMI) than European Whites, particularly relating to metabolic risk. UK maternal obesity guidelines use general population BMI criteria to define obesity, which do not represent the risk of morbidity among Asian populations. This study compares incidence of first trimester obesity using Asian-specific and general population BMI criteria.

METHOD

A retrospective epidemiological study of 502,474 births between 1995 and 2007, from 34 maternity units across England. Data analyses included a comparison of trends over time between ethnic groups using Asian-specific and general population BMI criteria. Logistic regression estimated odds ratios for first trimester obesity among ethnic groups following adjustment for population demographics.

RESULTS

Black and South Asian women have a higher incidence of first trimester obesity compared with White women. This is most pronounced for Pakistani women following adjustment for population structure (OR 2.19, 95% C.I. 2.08, 2.31). There is a twofold increase in the proportion of South Asian women classified as obese when using the Asian-specific BMI criteria rather than general population BMI criteria. The incidence of obesity among Black women is increasing at the most rapid rate over time (p=0.01).

CONCLUSION

The twofold increase in maternal obesity among South Asians when using Asian-specific BMI criteria highlights inequalities among pregnant women. A large proportion of South Asian women are potentially being wrongly assigned to low risk care using current UK guidelines to classify obesity and determine care requirements. Further research is required to identify if there is any improvement in pregnancy outcomes if Asian-specific BMI criteria are utilised in the clinical management of maternal obesity to ensure the best quality of care is provided for women irrespective of ethnicity.

Safety, tolerability, and efficacy of metformin extended-release oral antidiabetic therapy in patients with type 2 diabetes: an observational trial in Asia

BACKGROUND

The aim of the present prospective observational study was to assess the tolerability and antihyperglycemic efficacy of metformin extended-release (MXR) in the routine treatment of patients with type 2 diabetes mellitus (T2DM) from six Asian countries.

METHODS

Data from 3556 patients treated with once-daily MXR for 12 weeks, or until discontinuation, were analyzed.

RESULTS

Treatment with MXR was well tolerated, with 97.4% of patients completing 12 weeks of treatment. Only 3.3% of patients experienced one or more gastrointestinal (GI) side-effects and only 0.7% of patients discontinued for this reason (primary endpoint). The incidence of GI side-effects and related discontinuations appeared to be considerably lower during short-term MXR therapy than during previous treatment (mean 2.71 years' duration), most commonly with immediate-release metformin. A 12-week course of MXR therapy also reduced HbA1c and fasting glucose levels from baseline.

CONCLUSIONS

The present study provides new insights into the incidence of GI side-effects with MXR in Asian patients with T2DM and on the tolerability of MXR in non-Caucasian populations. Specifically, these data indicate that once-daily MXR not only improves measures of glycemic control in Asian patients with T2DM, but also has a favorable GI tolerability profile that may help promote enhanced adherence to oral antidiabetic therapy.

Interactions between obesity, parental history of hypertension, and age on prevalent hypertension: the People's Republic of China Study

Age, family history, and body mass index (BMI) influence the prevalence of hypertension, but very little is known about the interplay of these factors in Chinese populations. The authors examined this issue in Chinese adults (n = 4104) in the People's Republic of China Study. In young adults (24-39 years), the prevalence of hypertension/1000 persons (95% confidence interval [CI]) at the referent BMI was greater among subjects with a parental history of hypertension (35; 15-54) compared with those without (7; 3-11). Among middle-aged (40-71 years) adults, the prevalence of hypertension was similar regardless of parental history; however, the effect of BMI was modified by parental history status. For example, at BMI = 25 kg/m(2), the prevalence difference/1000 persons was 375 (95% CI = 245-506) and 97 (95% CI = 51-144) among subjects with and without a parental history, respectively. These large differences call for further investigation of the genetic and environmental factors that could be driving this interaction.
