Metric features of the ear are important for diagnosis of congenital malformations, pre-operative planning and design of hearing devices. Non-metric features including earlobe attachment is a marker of population genetics. Although these features vary with sex and populations, it’s unclear whether they show ethnic variations. This study describes ethnic differences in the morphology of the pinna. Both ears of one hundred and forty-eight (148) medical students (80males and 68 females) [recruited from four ethnic groups: Kenyan Indian, Kenyan Arab, Kikuyu and Luhya] were studied. Ear projection, heights and widths of ear, earlobe and concha were measured. For the Kenyan Indians, Arabs, Kikuyus and Luhyas respectively, proportion of free earlobes was 70.1%, 48.6%, 37.8%, 43.2%, attached lobes was 21.6% 27.1%, 42.9%, 32.4%. Mean earlobe height was 18.2mm, 16.7mm, 15.8mm, 15.8mm (p=0.001), ear projection at mid-tragus was 14.5mm, 13.5mm, 12.5mm, 12.6mm (p=0.035). Ethnic differences are present in earlobe height, attachment type and ear projection at mid-tragus. Earlobe height among indigenous Kenyans is significantly smaller compared to Kenyan Indians and Arabs. The attached earlobe is most prevalent among Kenyan indigenous while the free earlobe is most prevalent among Kenyan Indians. These features ought to be considered in aesthetic reconstruction of ear during earlobe rejuvenation and correction of projected ears.Keywords: Pinna morphology, Ethnic difference, Variations

Background Ethnic variations in pathways to early intervention in psychosis (EIP) have been studied. However, it is important to explore the ethnic variations in response to pharmacological treatment in EIP. Aims To look at ethnic variation in response to antipsychotics. Method Electronic patient records in December 2018 were perused for: Sociodemographic details including ethnicity Prescribed antipsychotic and dosage to which the patient had responded Results White, Black and Asian ethnic groups responded mostly to Olanzapine. The largest proportion of the mixed ethnic group responded to Aripiprazole. The White and Asian groups showed the best responses to Lurasidone at 74 mg. There was a slight response in the mixed and other ethnic groups only at the higher dose of 111 mg. The medication has not been used with any benefit in the Black ethnic group. Conclusion The complex differences highlighted amongst ethnic responses to treatment make a case for multi-centric studies to further explore ethnic differences in early intervention treatments. This will help streamline offered treatments to maximise response in EIP.

Abstract Background Ethnicity can influence susceptibility to infection, as COVID-19 has shown. Few countries have systematically investigated ethnic variations in infection. Methods We linked the Scotland 2001 Census, including ethnic group, to national databases of hospitalizations/deaths and serological diagnoses of bloodborne viruses for 2001–2013. We calculated age-adjusted rate ratios (RRs) in 12 ethnic groups for all infections combined, 15 infection categories, and human immunodeficiency virus (HIV), hepatitis B (HBV) and hepatitis C (HCV) viruses. Results We analysed over 1.65 million infection-related hospitalisations/deaths. Compared with White Scottish, RRs for all infections combined were 0.8 or lower for Other White British, Other White and Chinese males and females, and 1.2–1.4 for Pakistani and African males and females. Adjustment for socioeconomic status or birthplace had little effect. RRs for specific infection categories followed similar patterns with striking exceptions. For HIV, RRs were 136 in African females and 14 in males; for HBV, 125 in Chinese females and 59 in males, 55 in African females and 24 in males; and for HCV, 2.3–3.1 in Pakistanis and Africans. Conclusions Ethnic differences were found in overall rates and many infection categories, suggesting multiple causative pathways. We recommend census linkage as a powerful method for studying the disproportionate impact of COVID-19.

There is little data on ethnic differences in incidence of DR and sight threatening DR (STDR) in the United Kingdom. We aimed to determine ethnic differences in the development of DR and STDR and to identify risk factors of DR and STDR in people with incident or prevalent type II diabetes (T2DM). We used electronic primary care medical records of people registered with 134 general practices in East London during the period from January 2007–January 2017. There were 58,216 people with T2DM eligible to be included in the study. Among people with newly diagnosed T2DM, Indian, Pakistani and African ethnic groups showed an increased risk of DR with Africans having highest risk of STDR compared to White ethnic groups (HR: 1.36 95% CI 1.02–1.83). Among those with prevalent T2DM, Indian, Pakistani, Bangladeshi and Caribbean ethnic groups showed increased risk of DR and STDR with Indian having the highest risk of any DR (HR: 1.24 95% CI 1.16–1.32) and STDR (HR: 1.38 95% CI 1.17–1.63) compared with Whites after adjusting for all covariates considered. It is important to optimise prevention, screening and treatment options in these ethnic minority groups to avoid health inequalities in diabetes eye care.

BACKGROUND The prevalence of depression symptoms in the United States is >3 times higher mid–COVID-19 versus pre-pandemic. Racial/ethnic differences in mindsets around depression and the potential impact of the COVID-19 pandemic are not well characterized. OBJECTIVE To describe attitudes, mindsets, key drivers, and barriers related to depression pre– and mid–COVID-19 by race/ethnicity using digital conversations about depression mapped to health belief model (HBM) concepts. METHODS Advanced search, data extraction, and AI-powered tools were used to harvest, mine, and structure open-source digital conversations of US adults who engaged in conversations about depression pre– (February 1, 2019-February 29, 2020) and mid–COVID-19 pandemic (March 1, 2020-November 1, 2020) across the internet. Natural language processing, text analytics, and social data mining were used to categorize conversations that included a self-identifier into racial/ethnic groups. Conversations were mapped to HBM concepts (ie, perceived susceptibility, perceived severity, perceived benefits, perceived barriers, cues to action, and self-efficacy). Results are descriptive in nature. RESULTS Of 2.9 and 1.3 million relevant digital conversations pre– and mid–COVID-19, race/ethnicity was determined among 1.8 million (62%) and 979,000 (75%) conversations pre– and mid–COVID-19, respectively. Pre–COVID-19, 1.3 million conversations about depression occurred among non-Hispanic Whites (NHW), 227,200 among Black Americans (BA), 189,200 among Hispanics, and 86,800 among Asian Americans (AS). Mid–COVID-19, 736,100 conversations about depression occurred among NHW, 131,800 among BA, 78,300 among Hispanics, and 32,800 among AS. Conversations among all racial/ethnic groups had a negative tone, which increased pre– to mid–COVID-19; finding support from others was seen as a benefit among most groups. Hispanics had the highest rate of any racial/ethnic group of conversations showing an avoidant mindset toward their depression. Conversations related to external barriers to seeking treatment (eg, stigma, lack of support, and lack of resources) were generally more prevalent among Hispanics, BA, and AS than among NHW. Being able to benefit others and building a support system were key drivers to seeking help or treatment for all racial/ethnic groups. CONCLUSIONS Applying concepts of the HBM to data on digital conversation about depression allowed organization of the most frequent themes by race/ethnicity. Individuals of all groups came online to discuss their depression. There were considerable racial/ethnic differences in drivers and barriers to seeking help and treatment for depression pre– and mid–COVID-19. Generally, COVID-19 has made conversations about depression more negative, and with frequent discussions of barriers to seeking care. These data highlight opportunities for culturally competent and targeted approaches to address areas amenable to change that might impact the ability of people to ask for or receive mental health help, such as the constructs that comprise the HBM.

In this lecture, the writer calls the attention of Canadian psychiatrists to the unparalleled opportunities the national policy of multiculturalism has for clinical and research activities. Using illustrations from three important fields in psychiatry — epidemiology, psychopharmacology and psychotherapy, he points out the roles socio-cultural factors play in generating ethnic differences which deserve to be given serious scientific attention for both the understanding of causative factors and the treatment of mental disorders. He emphasizes that medical universalism and ethnocentricism have no place in Canadian psychiatry, and that the next phase of Canadian psychiatry should focus on cultural relevancy based on cultural relativism and equal participation of all cultures and ethnic groups.

Object The goal of this study was to determine racial/ethnic differences in inpatient mortality rates and the use of institutional postacute care following subarachnoid hemorrhage (SAH) in the US. Methods A cross-sectional study of hospital discharges for SAH was conducted using the Nationwide Inpatient Sample for the years 2005–2010. Discharges with a principal diagnosis of SAH were identified and abstracted using the appropriate ICD-9-CM diagnostic code. Racial/ethnic groups were defined as white, black, Hispanic, Asian/Pacific Islander (API), and American Indian. Multinomial logistic regression analyses were performed comparing racial/ethnic groups with respect to the primary outcome of risk of in-hospital mortality and the secondary outcome of likelihood of discharge to institutional care. Results During the study period, 31,631 discharges were related to SAH. Race/ethnicity was a significant predictor of death (p = 0.003) and discharge to institutional care (p ≤ 0.001). In the adjusted analysis, compared with white patients, API patients were at higher risk of death (OR 1.34, 95% CI 1.13–1.59) and Hispanic patients were at lower risk of death (OR 0.84, 95% CI 0.72–0.97). The likelihood of discharge to institutional care was statistically similar between white, Hispanic, API, and Native American patients. Black patients were more likely to be discharged to institutional care compared with white patients (OR 1.27, 95% CI 1.14–1.40), but were similar to white patients in the risk of death. Conclusions Significant racial/ethnic differences are present in the risk of inpatient mortality and discharge to institutional care among patients with SAH in the US. Outcome is likely to be poor among API patients and best among Hispanic patients compared with other groups.

Background: Subjective memory impairment (SMI) is associated with negative health outcomes including mild cognitive impairment and Alzheimer’s disease. However, ethnic differences in SMI and disparities in risk factors associated with SMI among minority populations are understudied. The study examined the ethnic differences in SMI, whether SMI was associated with depressive symptoms, sleep, and physical activity (PA), and whether the associations vary across racial/ethnic groups. Methods: Participants included 243 African and Asian Americans (including Chinese, Vietnamese, and Korean Americans) aged 50 or older. Demographic information, SMI, depressive symptoms, daily sleeping hours, and PA levels were assessed. Results: Vietnamese Americans reported the highest SMI score. Depressive symptoms, sleeping hours, and PA levels were significantly associated with SMI. Depressive symptoms were the only significant factor across all ethnic groups. Significant interaction effects were found between ethnicity and health behaviors in predicting SMI. In particular, Vietnamese American participants with greater depressive symptoms and physical inactivity were significantly more likely to experience SMI compared to other ethnic groups Conclusions: Our findings demonstrate ethnic differences in SMI and its association with depressive symptoms, sleep, and PA, which highlight the importance of considering the unique cultural and historical backgrounds across different racial/ethnic groups when examining cognitive functioning in elderly.

Iran is a country with different ethnicities and religions and some negative experiences of conflicts throughout history. It is believed that; Sports success is a factor in the greater convergence of a country's citizens. This article analyzes the ethnic differences of Iranian sports fans in Islamic cohesion, national identity, and perception of sports success. The research was a descriptive survey. The statistical population was all Iranians interested in national sports, 968 of whom participated in the study voluntarily. The research instruments were the researcher-made questionnaire of Perception of Sports Success, the National Identity Questionnaire of Hear and James (2007), and the Islamic Cohesion Questionnaire of Baghbanian and Morowat (2011). The content and face validity of the questionnaires were confirmed by the professors and their reliability was calculated with Cronbach's alpha coefficient of 0.78, 0.88, and 0.83, respectively. The test of hypotheses showed that; the variables of Islamic cohesion and national identity have a statistically significant difference between Shiite and Sunni respondents (P <0.05). The variables of Islamic cohesion and national identity also had a statistically significant difference between the respondents of ethnic groups (P <0.05) while there was no statistically significant difference in the perception of sporting success between the respondents of different ethnic groups and religious groups (P <0.05). The findings of the study emphasized the positive functions of sports success in the convergence of more religious and ethnic groups in the country.

Different Genetic Background

Background: Craniofacial anthropometry is a technique used in both physical and clinical anthropology comprising precise and systematic measurements of the human skull. It also includes measurement of the medial and lateral canthal distances. People of different genetic background subjected to significantly different environmental influences have different craniofacial morphology.Objectives: To find out effect of gender and ethnicity on Canthal anthropometry.Methods: This descriptive cross-sectional study was carried out to determine and compare canthal anthropometry among 299 undergraduate students (Male=161, Female=138) of different ethnic groups (Indo-Nepalese, indigenous and Tibeto-Nepalese) of age group 19-21 years at BPKIHS. Medial and lateral canthal distances were measured by using straight vernier caliper and canthal index (medial canthal distances / lateral canthal distance × 100) for all three ethnic groups in both sexes were compared.Results: The study has shown that the female students had higher canthal index than male students (27.65±12.35 vs 23.96±5.76). When compared on the basis of ethnicity, Indo-Nepalese had highest value of canthal index followed by Indigenous and Tibeto-Nepalese.Conclusion: In conclusion, genetics and environmental factors are responsible for the variation in canthal indices and other craniofacial indices between and within populations. Therefore, its standard values are largely applicable for clinical assessment of patients with syndrome affecting canthal anatomy.DOI: http://dx.doi.org/10.3126/jkmc.v3i2.11231Journal of Kathmandu Medical CollegeVol. 3, No. 2, Issue 8, Apr.-Jun., 2014Page: 78-81

AbstractBackgroundEthnic minorities have higher rates of SARS-CoV-2 diagnoses, but little is known about ethnic differences in past exposure. We aimed to determine whether prevalence and determinants of SARS-CoV-2 exposure varied between six ethnic groups in Amsterdam, the Netherlands.MethodsParticipants aged 25-79 years enrolled in a population-based prospective cohort were randomly selected within ethnic groups and invited to test for SARS-CoV-2-specific antibodies and answer COVID-19 related questions. We estimated prevalence and determinants of SARS-CoV-2 exposure within ethnic groups using survey-weighted logistic regression adjusting for age, sex and calendar time.ResultsBetween June 24-October 9, 2020, we included 2497 participants. Adjusted SARS-CoV-2 seroprevalence was comparable between ethnic-Dutch (25/498; 5.5%, 95%CI=3.2-7.9), South-Asian Surinamese (22/451; 4.8%, 95%CI=2.1-7.5), African Surinamese (22/400; 8.2%, 95%CI=3.0-13.4), Turkish (30/408; 7.8%, 95%CI=4.3-11.2) and Moroccan (32/391; 7.0%, 95%CI=4.0-9.9) participants, but higher among Ghanaians (95/327; 26.5%, 95%CI=18.7-34.4). 57.1% of SARS-CoV-2-positive participants did not suspect or were unsure of being infected, which was lowest in African Surinamese (18.2%) and highest in Ghanaians (90.5%). Determinants of SARS-CoV-2 exposure varied across ethnic groups, while the most common determinant was having a household member suspected of infection. In Ghanaians, seropositivity was associated with older age, larger household sizes, living with small children, leaving home to work and attending religious services.ConclusionsNo remarkable differences in SARS-CoV-2 seroprevalence were observed between the largest ethnic groups in Amsterdam after the first wave of infections. The higher infection seroprevalence observed among Ghanaians, which passed mostly unnoticed, warrants wider prevention efforts and opportunities for non-symptom-based testing.
