Background: Chronic hepatitis B (CHB) is a major cause of liver-related morbidity and mortality in the United States (US) and globally. CHB disproportionately affects Asian Americans and many other immigrant minority populations, primarily owing to the high prevalence of CHB in their countries of origin. India is a country with a medium-to-high prevalence of hepatitis B (HB) (>2%) and has over 40 million people infected with hepatitis B virus (HBV), with more than 115,000 deaths annually from HBV-related complications. Indian Americans are one of the largest immigrant populations in the US but remain underdiagnosed and poorly linked to clinical care. We, therefore, assessed the HBV prevalence and evaluated the linkage-to-care (LTC) among Indian Americans to develop strategic plans to reduce the impact of HBV in the US. Methods: Between April 2022 and January 2024, serologic screening and surveys were provided to 328 Indian American adults (age 20 - 80) in New York City. All participants were tested for a triple panel consisting of hepatitis B surface antigen (HBsAg), hepatitis B surface antibody (anti-HBs), and hepatitis B core IgG antibody (anti-HBc). A survey was conducted on the subjects chronically infected with HBV regarding their histories of infection. Self-administered questionnaires were employed to evaluate demographic and epidemiologic characteristics. Results: Of 328 screened and evaluated (246 males and 82 females), 10 (3.0%) were HBV-infected, 222 (67.7%) were susceptible to HBV, and 96 (29.3%) were immune. The prevalence of chronic HBV varied between the age groups: 4.6% (age 20 - 40), 3.4% (age 41 - 60), and 1.7% (age 61 - 80). Of 10 chronically infected, only two subjects had been previously diagnosed but were not engaged in care. Conclusion: HBV disproportionately affects Asian Americans, primarily owing to immigration from parts of the world where the disease is endemic. Indian Americans belong to an intermediate-risk group, with an HBV prevalence of >2%, but remain underdiagnosed and poorly linked to care. Our pilot study on Indian American populations, the first of its kind, demonstrates a 3% prevalence of CHB, none of whom are linked to care. In addition, this population has a high percentage of unimmune subjects, creating a large reservoir for future infection. With the growing population of Indian Americans, our findings can be used to develop community-based strategies for HBV screenings and LTC that target high-risk groups. 展开更多

Chronic hepatitis B (CHB) disproportionately affects minority groups in the US, particularly Asian Americans, with numerous factors contributing to this disparity. Of the 2.4 million people living with chronic HBV in the US, 60% are Asian American. Many are unaware of their status and lack access to proper clinical care, with less than ten percent receiving necessary antiviral treatment. Barriers to screening and care include lack of disease awareness, language and cultural barriers, and financial constraints. Additionally, healthcare providers and systems in the US often overlook the importance of CHB, leading to inadequate care. In response, the Center for Viral Hepatitis (CVH) has implemented a community-based outreach program over the past sixteen years, employing a multifaceted approach involving all sectors of society and various organizations to combat health disparities in CHB. This grassroots campaign has proven highly effective, leveraging CVH’s leadership in spearheading numerous collaborative activities with community members, healthcare professionals, and policymakers. We have summarized the key points of CVH's efforts and their significance in combating CHB-related health disparities. The CHB Screening and Awareness Campaign, tailored to the Asian American community, serves as a successful model for increasing CHB screening, linkage-to-care, and addressing socio-cultural barriers and health literacy. Insights from these outreach programs have guided the development of culturally relevant resources and education initiatives. These findings suggest that such community-driven approaches are essential for addressing health disparities. The strategies and outcomes of CVH’s efforts can inform future health initiatives for other minority communities in the US and globally. 展开更多

Based on the Corpus of Contemporary American English(COCA),this study examines acupuncture from the perspective of mass media.Acupuncture has been circulating throughout the Chinese Cultural Circle since the Qin and Han Dynasties,and has since spread directly or indirectly to the rest of the world.The United States boasts the world’s second-largest acupuncture market,with its laws,regulations,industry growth,research,and education all positively influencing the development of acupuncture in other nations.This study uses COCA to analyze the form and content of acupuncture’s dissemination in eight different types of media.The findings show that acupuncture appears in COCA a total of 1,788 times,with the highest frequency in magazines,followed by blogs,and the lowest frequency in fiction.These findings reveal the popularity of acupuncture in mass media in the United States and provide empirical data and insights for the future dissemination and development of acupuncture in the United States. 展开更多

Objective To describe whether or not there are gender differences in lower urinary tract symptoms(LUTS)prevalence and risk factors in community-dwelling older Chinese Americans.Methods We performed a secondary analysis of a prospective cross-sectional population-based survey of Chinese Americans aged 60 years and older between January 2011 and December 2013 in English,Mandarin,Cantonese,Taishanese,or Teochew.A clinical review of systems was used to assess LUTS,which included urinary frequency,urgency,burning and/or pain,blood in urine,and urinary incontinence.Results Of the total 3157 people queried,42%were men and 58%were women.More men reported LUTS compared to women(32.9%vs.28.6%,p=0.01).In a multivariable analysis,female gender(adjusted odds ratio[aOR]0.60,95%confidence interval[CI]0.49-0.73),being married(aOR 0.79,95%CI 0.65-0.97),and smoking(aOR 0.66,95%CI 0.49-0.88)were found to be protective,while traditional Chinese medicine use(aOR 1.51,95%CI 1.28-1.78),heart disease(aOR 1.54,95%CI 1.24-1.91),and anxiety(aOR 1.69,95%CI 1.25-2.28)were most strongly associated with increased odds of LUTS.When examining genders separately,being married was found to be protective only in women.Meanwhile,unique factors found in men were hypertension,heart disease,and practice of Tai Chi.Conclusion In this large population-based study,LUTS were more prevalent in older Chinese American men than women.We also found gender-specific factors that influenced the odds of reporting LUTS;however,traditional Chinese medicine use was the only factor that was shared by both genders.Future longitudinal investigations are needed to elucidate these underlying mechanisms to provide evidence-based and culture-specific guidelines for this rapidly growing population. 展开更多

The leaves of Bt (Bacillus thuringiensis) transgenic poplar (Populus nigra L.) and CpTI (Cowpea trypsin inhibitor) transgenic poplar ((P. tomentosa×P. bolleana)×P. Tomentosa) were taken to feed the 4th-5th-instar larvae of American white moth (Hyphantria cunea (Drury)) for determination of the activities of the protective enzyme system inside larvae’s body. The physiological and biochemical effects of the transgenic poplars on the larvae were studied. The results showed that the two kinds of transgenic poplars had similar effects on the protective enzyme system in the midgut of larvae. The activities of superoxide dismutase, catalase, and peroxidase in midgut of the larvae increased gradually, reached the highest value at a certain time, and then decreased suddenly. For the larvae that were fed with the leaves of Bt transgenic poplar, the peak value of superoxide dismutase and catalase presented at the time of 24-h feeding, while the peak of peroxidase took place at the time of 12-h feeding. The activities of these protective enzymes for the larvae that were fed with leaves of CpTI transgenic poplar peaked 12 h later than that of those fed with leaves of Bt transgenic poplar. The comparison of activities of the protective enzymes was also carried out between the larvae with different levels of intoxication. It was found that the activities of protective enzyme of the seriously intoxicant larvae were higher than that of the lightly intoxicant larvae. This difference was more obvious in the group treated with CpTI transgenic poplar. 展开更多

Isolationism and expansionism are two themes of American diplomacy. From the beginning of the state’s history, isolationism and expansionism have manifested themselves as two policy imperatives in American diplomacy. On the surface, isolationism and expansionism represent contradictory attitudes and assumptions about America’s proper relationship with the outside world: isolationism advocates diplomatic and military non-entanglement in world affairs; expansionism urges active involvement in external affairs. But in a deeper sense, both isolationism and expansionism are manifestations of American sense of mission, the belief that the US has a special role to perform for all nations in the world. Isolationism is a passive approach to accomplish that mission: it emphasizes the exemplary nature of their country. Expansionism stresses the need for active involvement to achieve that mission; thus, is an active approach to American mission. 展开更多
