Expanded Newborn Screening Using Genome Sequencing for Early Actionable Conditions

The feasibility of implementing genome sequencing as an adjunct to traditional newborn screening (NBS) in newborns of different racial and ethnic groups is not well understood. To report interim results of acceptability, feasibility, and outcomes of an ongoing genomic NBS study in a diverse population in New York City within the context of the New York State Department of Health Newborn Screening Program. The Genomic Uniform-screening Against Rare Disease in All Newborns (GUARDIAN) study was a multisite, single-group, prospective, observational investigation of supplemental newborn genome screening with a planned enrollment of 100 000 participants. Parent-reported race and ethnicity were recorded at the time of recruitment. Results of the first 4000 newborns enrolled in 6 New York City hospitals between September 2022 and July 2023 are reported here as part of a prespecified interim analysis. Sequencing of 156 early-onset genetic conditions with established interventions selected by the investigators were screened in all participants and 99 neurodevelopmental disorders associated with seizures were optional. The primary outcome was screen-positive rate. Additional outcomes included enrollment rate and successful completion of sequencing. Over 11 months, 5555 families were approached and 4000 (72.0%) consented to participate. Enrolled participants reflected a diverse group by parent-reported race (American Indian or Alaska Native, 0.5%; Asian, 16.5%; Black, 25.1%; Native Hawaiian or Other Pacific Islander, 0.1%; White, 44.7%; 2 or more races, 13.0%) and ethnicity (Hispanic, 44.0%; not Hispanic, 56.0%). The majority of families consented to screening of both groups of conditions (both groups, 90.6%; disorders with established interventions only, 9.4%). Testing was successfully completed for 99.6% of cases. The screen-positive rate was 3.7%, including treatable conditions that are not currently included in NBS. These interim findings demonstrate the feasibility of targeted interpretation of a predefined set of genes from genome sequencing in a population of different racial and ethnic groups. DNA sequencing offers an additional method to improve screening for conditions already included in NBS and to add those that cannot be readily screened because there is no biomarker currently detectable in dried blood spots. Additional studies are required to understand if these findings are generalizable to populations of different racial and ethnic groups and whether introduction of sequencing leads to changes in management and improved health outcomes.

Influence of religio-cultural beliefs on whole-body donation: A quantitative analysis of a predominantly South African Pedi Community

BackgroundBody donation is a predominant mode of body sourcing in many countries including South Africa; however, it continues to be limited among the different ethnic groups in the Black African population of South Africa which have been observed to be largely unwilling to provide consent to donate their bodies. Religious and cultural beliefs have been suggested to influence willingness to donate one’s body to science, with most religions regarded as accepting of body donation globally. In contrast, cultural beliefs and practices in the African continent impede body donation. Therefore, it is crucial to understand the factors that influence willingness to participate in body donation among the various ethnic groups of the Black African population of South Africa, particularly the Pedi ethnic group. PurposeThis study sought to investigate factors that determine the disposition to participate in body donation and the influence of religious and cultural beliefs on willingness to consent to donate one’s body among a predominantly Pedi community of the Black African population of South Africa in the Limpopo province. MethodsIn this cross-sectional study, 300 four-page questionnaires were distributed to conveniently sampled individuals from the GaMaphale (Pipa) village of the Limpopo province of South Africa. Descriptive statistics (frequency tables and Pearson’s chi-square test for independence) followed by a stepwise backward regression were conducted to obtain key factors determining willingness to donate one’s body, the influence of religious and cultural beliefs, and also the likelihood of willingness to participate in body donation in this community. A p-value of < 0.05 was considered statistically significant. ResultsA total of 190 (63 %) responses were obtained. The level of awareness about body donation was 30 % (n= 57/190), and 41 % (n= 78/190) of respondents were willing to donate their bodies. Age (p = 0.001), educational level (p = 0.037), belief in a higher entity (p = 0.007), ancestral (p < 0.001), and religious (p < 0.001) beliefs allowing for body donation were statistically associated with willingness to donate one’s body. The elderly respondents were less likely to agree to donate their bodies compared to younger adults. Respondents who understood that religion allowed them to self-donate were 50 times more likely to agree to donate their bodies than those who did not. Discussion and conclusionFindings reflect that a high percentage of respondents were unaware of body donation while a considerable number of respondents were willing to donate their bodies to science based on their religious and cultural beliefs allowing them to do so. Potential body donors from this community will likely be younger and belong to religions that allow body donation. The need to increase awareness about body donation programs through awareness campaigns, especially among religious organizations that may allow for body donation, is warranted in this community.This work was supported by the National Research Foundation (TTK220214660416).

A comparative ethnic study on the urban integration of the migrant populations in the Qinghai-Tibet Plateau during the process of urbanization

ABSTRACT This paper constructs an urban integration index system of the migrant population to compare differences in the level of urban integration among different ethnic groups on the Qinghai-Tibet Plateau. The study finds that Tibetan migrants have the highest level of urban integration, followed by Han and then Hui migrants. The migrants of each ethnic group have their own advantages in urban integration among the different dimensions used in this study. Han migrants have the highest level of economic integration, Tibetan migrants have the highest level of social participation, and Hui migrants have the highest level of psychological and cultural integration. There are also regional differences, with the level of urban integration of migrants in Qinghai Province being higher than that of migrants in the Tibet Autonomous Region. From the perspective of the different dimensions of integration, the economic integration of migrants in Qinghai Province and the social participation of migrants in the Tibet Autonomous Region have integration advantages. In addition, factors affecting the urban integration of the migrant population of different ethnic groups share some similarities and have some differences.

National Character and State Defense Based on Local Tapis Lampung Culture as an Effort to Strengthen National Identity

Indonesia, with a diverse population of many ethnic groups and rich cultural heritage, is a global, non-competitive multicultural country. Like the variety of flowers in this country's gardens, Indonesia's mosaic of cultures and beliefs is also diverse. Indonesia's rich cultural diversity attracts tourists and is a source of innovation for creative industries. In an effort to fortify Indonesian nationalism, this research aims to display handmade art works by Tapis Lampung. The research methodology used is qualitative using descriptive literature study methodology. Based on research findings, Tapis Lampung is a type of traditional textile that is embroidered with decorative sugi designs using cotton thread and silver or gold thread. The Lampung indigenous people store their life values and character in this Tapis cloth, which is also used in various traditional, religious and wedding events. One of the characteristics of Indonesian society is the Tapis Lampung cloth which is widely sold both domestically and internationally. Tapis Lampung is a cultural achievement of the Lampung people, according to examination from various sources.

Genetic Factors Contributing to the Pathogenesis of Essential Hypertension in Two African Populations.

The African continent has the highest prevalence of hypertension globally, with South Africa reporting the highest prevalence in Southern Africa. While the influence of genetic variability in the pathogenesis of hypertension is well described internationally, limited reports are available for African populations. This study aimed to assess the association of genetic variants and essential hypertension in a cohort of two ethnic South African population groups. Two hundred and seventy-seven hypertensive and one hundred and seventy-six normotensive individuals were genotyped for 78 variants. Genotyping was performed using the Illumina GoldenGate Assay and allele-specific polymerase chain reaction. The association of variants was assessed using the Fisher Exact test under the additive and allelic genetic models, while multivariate logistic regression was used to predict the development of hypertension. Five variants (CYP11B2 rs179998, AGT rs5051 and rs699, AGTR1 rs5186, and ACE rs4646994) were significantly associated with essential hypertension in the cohort under study. Furthermore, AGTR1 rs5186 and AGT rs699 were identified as risk factors for the development of hypertension in both ethnic groups. In two ethnic South African populations, an association was observed between renin-angiotensin-aldosterone system (RAAS)-related genes and the development of hypertension.

Racial and Ethnic Disparities in Geographic Availability of Buprenorphine.

Overdose mortality has risen most rapidly among racial and ethnic minority groups while buprenorphine prescribing has increased disproportionately in predominantly non-Hispanic White urban areas. To identify whether buprenorphine availability equitably meets the needs of diverse populations, we examined the differential geographic availability of buprenorphine in areas with greater concentrations of racial and ethnic minority groups. Using IQVIA longitudinal prescription data, IQVIA OneKey data, and Microsoft Bing Maps, we calculated 2 outcome measures across the continental United States: the number of buprenorphine prescribers per 1000 residents within a 30-minute drive of a ZIP code, and the number of buprenorphine prescriptions dispensed per capita at retail pharmacies among nearby buprenorphine prescribers. We then estimated differences in these outcomes by ZIP codes' racial and ethnic minority composition and rurality with t tests. Buprenorphine prescribers per 1000 residents within a 30-minute drive decreased by 3.8 prescribers per 1000 residents in urban ZIP codes (95% confidence interval = -4.9 to -2.7) and 2.6 in rural ZIP codes (95% confidence interval = -3.0 to -2.2) whose populations consisted of ≥5% racial and ethnic minority groups. There were 45% to 55% fewer prescribers in urban areas and 62% to 79% fewer prescribers in rural areas as minority composition increased. Differences in dispensed buprenorphine per capita were similar but larger in magnitude. Achieving more equitable buprenorphine access requires not only increasing the number of buprenorphine-prescribing clinicians; in urban areas with higher racial and ethnic minority group populations, it also requires efforts to promote greater buprenorphine prescribing among already prescribing clinicians.

Genetic diversity and seroprevalence of Toxoplasma gondii in COVID‑19 patients; a first case-control study in Iran

BackgroundToxoplasmosis is a serious or life-threatening disease in immunosuppressed patients and pregnant women. This study examined the likely association between Toxoplasma gondii infection and COVID-19 patients with moderate illness.MethodsSeventy blood samples were collected from patients at the Health Reference Laboratory of Tabriz, Northwest Iran from April 2021 to September 2021. In addition, 70 healthy subjects of the same age (37 ± 15 years) and sex distribution were ethnically matched. Sera samples were examined for the detection of anti-Toxoplasma antibodies using ELISA. Nested-PCR targets were amplified based on the B1 and GRA6 genes. GRA6 amplicons were subjected to sequencing and phylogenetic analysis.ResultsThe seroprevalence of toxoplasmosis based on IgG titer was 35.7% in the COVID‑19 patients and 27.1% in the control group, representing not to be associated with the Toxoplasma seropositivity in COVID‑19 patients (P = 0.18) compared to healthy subjects. Anti-T. gondii IgM was not found in any of the patients and healthy individuals. According to PCR amplification of the B1 and GRA6 genes, the frequency of T. gondii in COVID-19 patients was 14.2% (10/70). However, no T. gondii infection was detected in the healthy group. The CD4+T cell count was relatively lower in toxoplasmosis-infected patients (430–450 cells/mm3) than in control group (500–1500 cells/mm3). High genetic diversity (Hd: 0.710) of the type I strain of T. gondii was characterized in the patients. Present results showed that consumption of raw vegetables and close contact with stray cats can increase the transmission of T. gondii to COVID-19 patients (P < 0.01).ConclusionsThe current study revealed that T. gondii type I infection is unequivocally circulating among the COVID-19 patients in Tabriz; However, no significant association was observed between the occurrence of Toxoplasma and the severity of COVID-19. To make more accurate health decisions, multicenter investigations with a larger sample size of different ethnic groups of the Iranian population are needed.

Is There An "Ideal Instagram Face" for Caucasian Female Influencers? A Cross-Sectional Observational Study of Facial Proportions in 100 Top Beauty Influencers.

In the digital arena, wherein younger generations predominantly spend their time, social media continues to determine what is considered beautiful. Social media, particularly Instagram (Meta, Menlo Park, CA), is becoming a prominent aspect of the plastic surgeon-patient relationship. Therefore, the beauty ideal escalates without any barriers and breaks. The majority of influencers look alike. This sets a new trend for a beauty ideal. In this study, the authors aimed to analyze the facial proportions of 100 top female beauty influencers, to evaluate them for identifying the "ideal Instagram face," and to determine whether there existed a deviation from the standard golden ratio. The authors identified the top 100 beauty influencers, according to the latest rankings of November 2022. A detailed facial analysis has been conducted using the Fiji biomedical image analysis software. The primary outcome parameters included facial proportions such as lip ratio, Ricketts' line, and nasal dimensions. Secondary outcomes comprised BMI, age, and ethnicity. The results were collected and analyzed descriptively using graphs and statistics. Complete datasets were obtained from the top 100 female beauty influencers with a mean age of 31.3 ± 6.3 years (range, 24-38 years). The majority of influencers were Americans, followed by Germans and British. Based upon the mean of the aforementioned parameters, we could design the ideal Instagram face. There was no significant difference between the golden ratio and the new trend of the ideal Instagram face. Despite the existence of varied ethnic population groups and nonstandard measurements, the ideal Instagram face represents today's ideal trending face. The ideal Instagram face is symmetrical, matching the golden ratios, with a small and neat nose, full and lush lips, high cheekbones, as also a sharp and chiseled jawline. Further studies on this topic, involving a greater number of influencers with standardized measurements, should be advocated to identify the ideal facial proportions. This will lead to improvements in invasive and noninvasive cosmetic treatments.

THE EXISTENCE OF CERTAIN ETHNIC GROUPS IN ODESA IN THE CONDITIONS OF OCCUPATION 1941–1944

The article is devoted to the existence of certain ethnic groups in Odesa under the conditions of occupation in 1941–1944. After all, the national policy of the Romanian occupation authorities in Odesa not only directly influenced the life strategy of representatives of certain ethnic groups of the city population, but in some cases the very possibility of survival or death depended on, which was recorded in the passport in the «nationality» column. It has been proved that three ethnic groups received the greatest privileges from the new government: Germans, Romanians and Moldovans. Since the ethnic Germans outside Germany were perceived by the Hitler government as representatives of a superior race, who were to be used in the new territories as allies in the implementation of the occupation policy, a separate unit of the SS «R» was created to work with the German population of Transnistria Governorate, which was subordinate to the Main Board of Repatriation of ethnic Germans «Volksdeutsche Mittelstelle». It was established that the Romanian government understood the need to focus its national policy on the Moldavian ethnic community in the region, because it was this population that was to become the support of the government in the temporarily occupied territory. That is, Moldovans began to be considered an ethnic group of the Romanian population. It is significant that about 250,000 Moldovans lived in the territory between the Dniester and the Bug, who were concentrated as much as possible in the villages along the Dniester. However, despite the loss of population in the first year of the war, the number of such residents decreased to 198,000. The occupiers immediately began to implement the priority policy of this particular nation. Therefore, the main bet was placed on them, as the support of the government in the new territories. Moldovans were declared an ethnic group of the Romanian population. The desire of the Romanian authorities is understandable: in this way they proved that this is historically their territory and they came «to protect their population». As for the attitude towards the Slavic peoples, namely Ukrainians, Russians, Bulgarians and Poles, all the documents show that they had a much lower status in the occupied city. Their position cannot in any way be compared with the attitude of the occupying power towards the privileged Romanians and Germans. Yes, they were not totally exterminated, like Romani people or Jews. Rather, they were seen as a necessary labour resource to be fully subjugated by the new masters. Therefore, in the case of loyalty to the occupiers, nothing formally threatened them, but it is quite difficult to call the conditions of their existence «absolutely favourable». The situation of the local Jews was the most difficult. A sufficient number of documents and studies have been presented, which prove that the policy of the Romanian occupation authorities in relation to them was dictated by the doctrine of the ethnocratic state and, as a result, provided for the total destruction of the local Jewish population. The attitude towards the Jews was understandable and became a continuation of political processes and the involvement of Romania in the sphere of influence of Germany. The Holocaust of the Jews of Bukovina and the Jews of the Old Kingdom, Bessarabia or Transnistria was dictated by the doctrine of the ethnocratic state. At the meeting of the Council of Ministers on February 7, 1941, I. Antonescu first raised the issue of introducing measures against the Romani people. As a result, a number of orders appeared where the main mechanism of the Romanian government became deportation from the territory of Romania to Transnistria. But it is important to note that, we have not found a single document in the archives about the relations between the occupation authorities and the Romani people directly in Odesa. Considering that according to the census of 1942 there were only 5 of them, we can allow not to consider them as a representative separate group. Consequently, Odesa citizens were forced to build a strategy for their survival in the conditions of occupation in accordance with the entry in the column «nationality» in the passport. On the highest steps of this cynical «racial pyramid», the occupiers placed Moldovans, Romanians and Germans. Below them were supposed to be Ukrainians, Russians, Poles and representatives of other ethnic groups of multinational Odesa. And somewhere outside this pyramid, the doomed Jews and Romani people were pushed out.

ETHNIC DIFFERENCES IN HEALTHY LIFE EXPECTANCY IN CHILE

Abstract Socioeconomic and sex differences in life expectancy (total and healthy) in Chile have been well established. However, the existence of ethnic differences in population longevity is unknown. Thus, we estimate total, healthy, and unhealthy life expectancy among Mapuche (largest indigenous group) and non-Mapuche older adults (≥60 years) in Chile. We estimated abbreviated mortality tables (using indirect demographic methods) and with the EDES health prevalence we applied Sullivan’s method. Disability was defined as the unhealthy state, evaluated through the methodology suggested by Albala et al. (2004). Results show that at age 60 the Mapuche have a life expectancy 7 years lower (26.4 vs. 18.9 years respectively). Although differences diminish with age, Mapuches always have lower total life expectancy. In addition, we detected that the proportion of disability-free life years is higher for non-Mapuche (1.5, 2.0 and 3.7 times higher at 60, 75 and 90 years respectively). In contrast, Mapuches expect to live a higher fraction of their life with disability compared to non-Mapuche (e.g., 84.1% vs. 62.9% at age 80). This is the first study addressing inequities in healthy life expectancy between the Mapuche ethnic group and non Mapuche population, reflected in lower life expectancy, lower healthy life expectancy and higher disabled life expectancy in Mapuche when compared with no Mapuche population.

Changes in mixed ethnicity households and neighbourhood transitions in England and Wales.

Conventional explanations of neighbourhood ethnic transitions consider what drives differential growth in ethnic group populations without regard to household composition. We enrich these nonhousehold approaches by using consistent Census data on neighbourhoods and households for England and Wales for 2001, 2011 and 2021 to analyse connections between mixed-ethnicity households and neighbourhood ethnic diversity. We employ a neighbourhood typology of ethnic diversity that identifies neighbourhoods as either low- or moderate-diversity, or high-diversity, where no single ethnic group is in the majority. We focus particularly on White-majority and highly diverse neighbourhoods given the dominance of the former in residential spaces in England and Wales, and because they are the principal source of transitions to highly diverse neighbourhoods. Mixed-ethnicity households have become an increasingly important feature of the ethnic diversification of England and Wales; by 2021, almost 15% of multiperson households were mixed, a growth from 12% in 2011 and 9% in 2001. We find that higher levels of neighbourhood ethnic diversity are associated with higher shares of mixed-ethnicity households. In high-diversity neighbourhoods, for example, around 30% of multiperson households (nearly a quarter of a million households) were ethnically mixed in 2021. Levels of household mixing in moderate-diversity White neighbourhoods were considerably higher than in low-diversity White neighbourhoods. The same is found for diversifying neighbourhoods. Neighbourhoods that become more ethnically diverse were typically home to higher rates of mixed-ethnicity households. Stably moderately diverse White neighbourhoods also had a higher proportion of mixed households. Studies of neighbourhood transition that focus on individuals in neighbourhoods may be missing important processes operating in the intimate spaces of the home. Including this intermediate scale of analysis adds to our understanding of neighbourhood ethnic mixing and processes of integration.

Screening and Colonoscopy Quality Measures: Ethnic Disparities and Impact on Patients' Outcome.

Recent reports have confirmed the improving trends in colorectal cancer (CRC) incidence and outcomes. Still, disparities in incidence and mortality in CRC continue to persist between major ethnic groups despite the provision of widespread screening and improved care. We aimed to outline, from an endoscopic point of view, ethnic disparities in major endoscopic measures concerned with CRC screening and detection and track their impact on patients' outcomes. We reviewed electronic reports of patients referred for colonoscopy procedures over 20 years. We compared demographic, clinical, and endoscopic findings between major ethnic population groups in Israel. In addition, trends of screening utilization, bowel preparation, and polyp detection rates were tracked, and the incidence of CRC diagnosis was followed. A total of 51307 patients had undergone colonoscopies, of whom 16% were Arabs, and 84% were Jewish. The procedures performed for CRC screening throughout the study period were significantly lower in Arabs (5% vs. 13.1%; P < 0.0001). In parallel, for most of the follow-up period, the Arab patients had higher rates of inadequate bowel preparation (overall: 19.9% vs. 12%; P < 0.001) and a lower polyp detection rate (16.7% vs. 22.5%; P < 0.0001). Expectedly, the incidence of CRC has steadily decreased in the Jewish group, while an adverse pattern of increasing incidence was documented in the Arab patient during the follow-up period. Characterized by lower screening utilization and poor bowel preparation, the incidence of CRC development in Arab patients is increasing, while improving trends of CRC were observed in their Jewish counterparts.

ФАКТОР ЭТНОКУЛЬТУРНОГО РАЗНООБРАЗИЯ В РЕГИОНАЛЬНОМ РАЗВИТИИ США

The regional development of one of the largest federations in the world — the United States of America, which is distinguished by the extreme diversity of the population and human potential of various territories and the uneven development of the economy — is historically influenced by the factor of ethnocultural diversity. In recent decades, American federalism has been characterized by a qualitatively “new” trend associated with the regionalization of social and economic relations in the context of regional systems. Based on a theoretical and methodological review of existing studies on the relationship between economic development, ethno-demographic heterogeneity and cultural evolution in the United States, using the necessary econometric methodological support, both theoretical and a number of empirical regression models were constructed. The specifi cation and analysis of the modeling results made it possible to put forward and reasonably confirm hypotheses that refl ect the differentiation of the factor of ethnocultural diversity in the regional development of the United States depending on the mutual influence of concomitant factors, the increasing role of the cultural component and the need to determine the optimal level of ethnocultural diversity for the regions of the country that have retained or are gradually changing their socio-economic genotype. It has been established that the program regulation of regional development in order to equalize the incomes of the population of various ethnic groups, carried out within the framework of the state regional policy of the United States, is largely selective in nature and is generally successful in the retrospective period.

Influence of ethnicity on adherence to nonsurgical interventions for COPD: a scoping review.

Poor therapeutic adherence and the contributing factors have been extensively researched in several chronic diseases, including COPD. However, the influence of ethnicity on adherence to nonsurgical treatment interventions for COPD (e.g. smoking cessation and pulmonary rehabilitation) is not well understood. This scoping review was performed to better understand variations in adherence among people from minority ethnic communities diagnosed with COPD. This scoping review was designed based on the refined frameworks of Arksey and O'Malley, developed by JBI (Joanna Briggs Institute). Systematic searches were performed across three databases: CINHAL (EBSCO), MEDLINE (Ovid) and Embase (Ovid). Out of 3654 identified records, 37 studies were deemed eligible for inclusion; these were conducted in various countries and involved populations of diverse ethnic groups diagnosed with COPD. The included studies considered provision and/or adherence to medication (n=8, 21.6%), smoking cessation (n=11, 29.7%), influenza vaccinations (n=7, 18.9%), pulmonary rehabilitation (n=11, 29.7%) and oxygen therapy (n=2, 5.4%). Outcomes varied widely between studies within a single intervention (e.g. initiation, adherence and completion of pulmonary rehabilitation programme). However, most of the included studies suggested the presence of inequalities linked to ethnicity across interventions. This review indicated the presence of poor adherence to nonsurgical interventions among people from minority ethnic backgrounds living with COPD. However, due to the heterogeneity in population groups considered and compared within the individual studies, it is challenging to identify and understand the key inequalities influencing adherence to nonsurgical interventions. Further research is needed to better explore this.

Stillbirth risk and smallness for gestational age according to Hadlock, INTERGROWTH-21st, WHO, and GROW fetal weight standards: analysis by maternal ethnicity and body mass index

Appropriate growth charts are essential for fetal surveillance, to confirm that growth is proceeding normally and to identify pregnancies that are at risk. Many stillbirths are avoidable through antenatal detection of the small-for-gestational-age fetus. In the absence of an international consensus on which growth chart to use, it is essential that clinical practice reflects outcome-based evidence. This study investigated the performance of 4 internationally used fetal weight standards and their ability to identify stillbirth risk in different ethnic and maternal size groups of a heterogeneous population. We analyzed routinely collected maternity data from more than 2.2 million pregnancies. Three population-based fetal weight standards (Hadlock, Intergrowth-21st, and World Health Organization) were compared with the customized GROW standard that was adjusted for maternal height, weight, parity, and ethnic origin. Small-for-gestational-age birthweight and stillbirth risk were determined for the 2 largest ethnic groups in our population (British European and South Asian), in 5 body mass index categories, and in 4 maternal size groups with normal body mass index (18.5-25.0 kg/m2). The differences in trend between stillbirth and small-for-gestational-age rates were assessed using the Clogg z test, and differences between stillbirths andbody mass index groups were assessed using the chi-square trend test. Stillbirth rates (per 1000) were higher in South Asian pregnancies (5.51) than British-European pregnancies (3.89) (P<.01) and increased in both groups with increasing body mass index (P<.01). Small-for-gestational-age rates were 2 to 3-fold higher for South Asian babies than British European babies according to the population-average standards (Hadlock: 26.2% vs 12.2%; Intergrowth-21st: 12.1% vs 4.9%; World Health Organization: 32.2% vs 16.0%) but were similar by the customized GROW standard (14.0% vs 13.6%). Despite the wide variation, each standard's small-for-gestation-age cases had increased stillbirth risk compared with non-small-for-gestation-age cases, with the magnitude of risk inversely proportional to the rate of cases defined as small for gestational age. All standards had similar stillbirth risk when the small-for-gestation-age rate was fixed at 10% by varying their respective thresholds for defining small for gestational age. When analyzed across body mass index subgroups, the small-for-gestation-age rate according to the GROW standard increased with increasing stillbirth rate, whereas small-for-gestation-age rates according to Hadlock, Intergrowth-21st, and World Health Organization fetal weight standards declined with increasing body mass index, showing a difference in trend (P<.01) to stillbirth rates across body mass index groups. In the normal body mass index subgroup, stillbirth rates showed little variation across maternal size groups; this trend was followed by GROW-based small-for-gestation-age rates, whereas small-for-gestation-age rates defined by each population-average standard declined with increasing maternal size. Comparisons between population-average and customized fetal growth charts require examination of how well each standard identifies pregnancies at risk of adverse outcomes within subgroups of any heterogeneous population. In both ethnic groups studied, increasing maternal body mass index was accompanied by increasing stillbirth risk, and this trend was reflected in more pregnancies being identified as small for gestational age only by the customized standard. In contrast, small-for-gestation-age rates fell according to each population-average standard, thereby hiding the increased stillbirth risk associated with high maternal body mass index.

Sexual Dimorphism in Teeth Dimension and Arch Perimeter of Individuals of Four Ethnic Groups of Northeastern India.

Objectives There is a disparity between males and females when it comes to size and appearance. In forensic and anthropological investigations, it is crucial to identify an unknown individual's gender, and it is possible to discern individual differences based on differences in dental features among populations. For identifying individuals, tooth dimensions are an effective, simple, and low-cost means of determining sex. Based on dental casts, this study aims to assess sexual dimorphism among four ethnic tribes of Northeast India using the mesiodistal (MD) dimension of canines and arch perimeter (AP) of the upper and lower jaws. Methods In each of the four ethnic groups studied, 50 males and 50 females with dental casts were measured in millimetres for the MD dimension of canines and AP of the upper and lower jaws. SPSSversion 20(IBM Corp., Armonk, NY) was used to analyze the data based on Student's t-test, considering a p-value of <0.05 as significant. Results Males had significantly larger MD dimensions of canines in the maxillary and mandibular jaws (p-value<0.05). The AP of both maxilla and mandible are higher in males than females in all four ethnic groups. However, the difference between the two genders for the AP of the maxilla is statistically significant only in Meitei and Singpho groups (p-value<0.05). In the case of the mandibular jaw, the AP was significantly lower in females in all four ethnic groups (p-value<0.05). Conclusion Significant sexual dimorphism exists among the individuals in the four ethnic group populations. The MD dimension and AP are essential to establish sexual dimorphism among populations. The MD dimension of the maxillary and mandibular canine and AP showed significant sexual dimorphism in the present study among all four ethnic groups.

The Status of Tribal Languages of Assam Based on Linguistic Context

Assam is home to a diverse population of ethnic and linguistic groups. Assamese is one of these languages and is used in Assam as a state language and a means of communication. Furthermore, since Assamese is the primary language of instruction in government institutions, all students, regardless of their multilingualism, receive a formal education in Assamese. In Assam, only members of that particular tribe speak the tribal language. Due to the lack of a script, these languages are not historically significant. With the use of another language’s script, certain languages are written. However, in terms of written literature, the languages could not be extravagant. In addition, there is a lot of adversity, which makes it difficult for languages to advance without facing these obstacles. This difficulty has become more important due to current, entirely unknown advancements in science and technology, the expansion of transportation and communication, as well as the advancement of education, etc. Additionally, the endangered languages are threatened due to their restricted use. In this instance, the study discusses the current state of these Assamese languages, the issues with tribal languages, the growth of the language, and the responsibilities associated with maintaining these languages. This essay also discusses the extent of Assamese tribal languages’ endangerment and evaluates their viability in light of the criteria suggested by UNESCO. We may draw the conclusion from the study that adequate language planning and all essential action should be taken by the government and the integrated tribe in order to preserve these languages. The only acceptable and reliable language for the present and the future will inspire and draw the following generation to adopt the same.

SOLDIERS’ UNREST DURING MOBILIZATION IN THE TERRITORY OF TATARSTAN DURING THE FIRST WORLD WAR (by the documents of the State Archive of the Republic of Tatarstan)

The purpose of the publication is to restore the event and the ethno-psychological aspects of mobilization of 1914 in Kazan province within the territories that are currently administratively make part of the Republic of Tatarstan. The novelty of the work consists in studying the issue of soldiers’ unrest and illegal actions of other social strata of Kazan governorate during soldiers’ conscription in July 1914. Unpublished archival sources of the State Archive of the Republic of Tatarstan were the basis for studying the aspects of the issue of coordinating the actions of power and municipal state structures in the person of municipal government and local military leadership with various ethnic and social groups of the local population during conscription at the beginning of the First World War. The destructive component of soldiers’ unrest and riots is considered in the context of social conflict theory developed by the political analyst T. Skochpol and the concept of functional intra-ethnic conflict created by the cultural studies scholar, sociologist and ethnologist S.V. Lurie. The issues of the dynamics in the expression of deviant behavior of conscripted servicemen in Kazan, Laishevsky, Spassky and Chistopol uyezds of Kazan governorate are elucidated. Attention is paid to the social, ethnic, psychological and religious motives of the lower ranks’ riots in the region. Such an important aspect of the problem as the causes of unfavorable mobilization course within the borders of the governorate at the beginning of the war is studied. The article identifies and touches upon the issue of the main forms of social aggression in the soldier masses, the trigger of which was introduction of the “prohibition law”.

A Cascade of Care Model for Suicide Prevention

Suicide remains the second leading cause of death for youth aged 15–19 years in the U.S. From 2011 to 2018, suicide rates in the U.S. increased, whereas the rates in other world regions decreased. 1 WHOSuicide worldwide in 2019: global health estimates.

Provisional numbers and rates of suicide by month and demographic characteristics: United States. Centers for Disease Control and Prevention, Atlanta, GA2020https://stacks.cdc.gov/view/cdc/110369 Google Scholar The magnitude of suicide in the U.S. and related disparities underlines the need for a response that specifically focuses on addressing inequities, including implementation gaps in the delivery and sustainment of best practices to all of those who could benefit. Since 2001, the U.S. has had a national strategy to address suicide, yet >20 years later, it has failed to accomplish all its goals and did not specifically focus on ending suicide-related health disparities. In this paper, an alternative model, a suicide-specific Cascade of Care (COC) model, is proposed, to guide a more equitable, inclusive, and scalable national suicide-prevention response.

Analysis of deprivation distribution in New Zealand by ethnicity, 1991-2013.

To compare the distribution of Māori and New Zealand (NZ) European populations in Aotearoa New Zealand by neighbourhood deprivation, for the five censuses between 1991 and 2013, and to identify changes in the distribution pattern over time. Geographical meshblock data from the 1991-2013 New Zealand censuses, by NZDep Index deprivation score, and by prioritised ethnic group population, were combined to analyse ethnic population counts by deprivation decile and deprivation score. Trends over time were analysed. Māori were over-represented in the more deprived NZDep deciles and under-represented in the least deprived deciles for all census periods. The NZ European population were over-represented in the least deprived deciles, and under-represented in the more deprived deciles. In each census, over 40% of the Māori population have been living in the two most deprived deciles, compared to less than 15% for NZ European. The patterns of inequity in socio-economic deprivation between Māori and NZ Europeans have remained virtually unchanged since 1991, despite various Government commitments to reduce inequity. Socio-economic deprivation for Māori is a key determinant of health inequity, and bolder Government measures prioritised for Māori are needed to change this socio-economic gradient if health equity goals are to be met.
