Ethnic-racial socialization messages given to multiracial youth: a person-centered analysis
The multiracial population is the fastest growing racial group in the United States, and almost half of the multiracial population nationwide is under the age of 18. Despite the rapidly growing numbers of young multiracial individuals, little is understood about how these individuals are socialized around race and ethnicity, and how these socialization messages are related to ethnic-racial identity development. This study utilizes a person-centered framework with a diverse sample of 296 multiracial college students to examine the patterns of ethnic-racial socialization messages individuals received from their primary caregivers. Latent profile analyses of caregiversâ messages produced a four-profile solution for both caregivers, with slightly different patterns (Caregiver 1: Typical, Minority, High Mistrust, and Low Frequency Messages; Caregiver 2 Typical, Negative, Promotive, and Low Frequency Messages). Overall, caregivers gave consistent socialization messages across both sides of participants ethnic-racial heritage. Similarly, about 60% of participants received consistent patterns of messages across caregivers. Finally, profile differences were evident with respect to ethnic-racial identity endorsement and multiracial identity integration. These findings add needed quantitative clarity to the patterns of socialization messages multiracial youth receive. Implications for parenting and future directions for research with multiracial populations are also discussed
Protecting minoritized youth against discrimination: the concurrent impact of ethnic-racial identity and culturally-congruent shift-&-persist coping
Discrimination is a largely uncontrollable stressor that has a negative impact on the psychological health and wellbeing of racially and ethnically minoritized youth. From a strengths-based perspective, this integrative dissertation presents a testable conceptual model of the general and culturally-informed coping methods that, in addition to other cultural assets such as ethnic-racial identity, may help promote resilience in minoritized youth and reduce the negative psychosocial impact of discrimination. Evidence for aspects of this conceptual model is demonstrated through three quantitative studies of minoritized adolescents and emerging adults. Implications for the study of culturally-informed coping and resilience in the face of uncontrollable racialized stressors are discussed
First Detection of Leishmania major DNA in Sergentomyia (Spelaeomyia) darlingi from Cutaneous Leishmaniasis Foci in Mali
Leishmania major complex is the main causative agent of zoonotic cutaneous leishmaniasis (ZCL) in the Old World. Phlebotomus papatasi and Phlebotomus duboscqi are recognized vectors of L. major complex in Northern and Southern Sahara, respectively. In Mali, ZCL due to L. major is an emerging public health problem, with several cases reported from different parts of the country. The main objective of the present study was to identify the vectors of Leishmania major in the Bandiagara area, in Mali. Methodology/Principal Findings: An entomological survey was carried out in the ZCL foci of Bandiagara area. Sandflies were collected using CDC miniature light traps and sticky papers. In the field, live female Phlebotomine sandflies were identified and examined for the presence of promastigotes. The remaining sandflies were identified morphologically and tested for Leishmania by PCR in the ITS2 gene. The source of blood meal of the engorged females was determined using the cyt-b sequence. Out of the 3,259 collected sandflies, 1,324 were identified morphologically, and consisted of 20 species, of which four belonged to the genus Phlebotomus and 16 to the genus Sergentomyia. Leishmania major DNA was detected by PCR in 7 of the 446 females (1.6%), specifically 2 out of 115 Phlebotomus duboscqi specimens, and 5 from 198 Sergentomyia darlingi specimens. Human DNA was detected in one blood-fed female S. darlingi positive for L. major DNA. Conclusion: Our data suggest the possible involvement of P. duboscqi and potentially S. darlingi in the transmission of ZCL in Mali

A year of genomic surveillance reveals how the SARS-CoV-2 pandemic unfolded in Africa.
The progression of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in Africa has so far been heterogeneous, and the full impact is not yet well understood. In this study, we describe the genomic epidemiology using a dataset of 8746 genomes from 33 African countries and two overseas territories. We show that the epidemics in most countries were initiated by importations predominantly from Europe, which diminished after the early introduction of international travel restrictions. As the pandemic progressed, ongoing transmission in many countries and increasing mobility led to the emergence and spread within the continent of many variants of concern and interest, such as B.1.351, B.1.525, A.23.1, and C.1.1. Although distorted by low sampling numbers and blind spots, the findings highlight that Africa must not be left behind in the global pandemic response, otherwise it could become a source for new variants
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance.
Investment in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing in Africa over the past year has led to a major increase in the number of sequences that have been generated and used to track the pandemic on the continent, a number that now exceeds 100,000 genomes. Our results show an increase in the number of African countries that are able to sequence domestically and highlight that local sequencing enables faster turnaround times and more-regular routine surveillance. Despite limitations of low testing proportions, findings from this genomic surveillance study underscore the heterogeneous nature of the pandemic and illuminate the distinct dispersal dynamics of variants of concern-particularly Alpha, Beta, Delta, and Omicron-on the continent. Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve while the continent faces many emerging and reemerging infectious disease threats. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance
INTRODUCTION
Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic.
RATIONALE
We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs).
RESULTS
Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants.
CONCLUSION
Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century
Strategies for Improving Self-Efficacy: A Qualitative Analysis of Detroitâs Downtown Boxing Gym
Structural inequalities present throughout U.S. public schools are known to contribute to the significant achievement gaps that persist between lower-income students of color and their more financially secure, White peers. Because of this, community programs have been identified as places where typically underserved students can receive the support required for positive development and academic achievement. The current study used qualitative methods to explore how one community program, Detroitâs Downtown Boxing Gym, fosters self-efficacy in school-aged youth from Detroit Public Schools. Focus group participants reported they are indeed experiencing increases in self-efficacy as a result of the mastery experiences, vicarious experiences, and verbal persuasion they receive at the gym. Specific recommendations for how other programs might foster self-efficacy, including establishing a program climate where students feel cared for, ensuring program staff truly believe students can be successful, identifying opportunities for students to have mastery experiences, and utilizing peer modeling, are discussed

Longitudinal links between maternal cultural socialization, peer ethnicâracial discrimination, and ethnicâracial pride in Mexican American youth
This paper used cross-lagged panel models to test the longitudinal interplay between maternal cultural socialization, peer ethnic-racial discrimination, and ethnic-racial pride across 5th to 11th grade among Mexican American youth (N = 674, Mage = 10.86; 72% born in the United States; 50% girls; Wave 1 collected 2006-2008). Maternal cultural socialization predicted increases in subsequent youth ethnic-racial pride, and youth ethnic-racial pride prompted greater maternal cultural socialization. However, peer ethnic-racial discrimination was associated with subsequent decreases in ethnic-racial pride. The magnitude of these associations was consistent across 5th to 11th grades suggesting that maternal cultural socialization messages are necessary to maintain ethnic-racial pride across adolescence, thus families must continually support the development of ethnic-racial pride in their youth to counter the effects of discrimination

When Discrimination Hurts: The Longitudinal Impact of Increases in Peer Discrimination on Anxiety and Depressive Symptoms in Mexican-origin Youth
Life course models of the impact of discrimination on health and mental health outcomes posit that the pernicious effects of discrimination may not be immediate, but instead may become apparent at later stages in development. This study tests whether peer discrimination changes at particular transition points (i.e., transition to middle and high school) predict subsequent internalizing symptoms in Mexican-origin youth. In a sample of 674 Mexican-origin youth (50% female), this study used a latent change score framework to model changes in peer discrimination across time and to test whether changes in peer discrimination at 7th and 9th grades predicted greater depressive and anxiety symptoms in 12th grade controlling for 5th grade symptoms. Irrespective of longitudinal changes, greater peer discrimination in 5th grade predicted greater depressive and anxiety symptoms in 12th grade. Further, significant increases in peer discrimination from 7th to 8th grade and in 9th to 10th grade uniquely predicted greater anxiety symptoms in 12th grade. These findings suggest that longitudinal research on peer discrimination needs to take into account unique periods of risk. Future research implications are discussed
