Educational disparities in brain health and dementia across Latin America and the United States.

BACKGROUND: Education influences brain health and dementia. However, its impact across regions, specifically Latin America (LA) and the United States (US), is unknown. METHODS: A total of 1412 participants comprising controls, patients with Alzheimer's disease (AD), and frontotemporal lobar degeneration (FTLD) from LA and the US were included. We studied the association of education with brain volume and functional connectivity while controlling for imaging quality and variability, age, sex, total intracranial volume (TIV), and recording type. RESULTS: Education influenced brain measures, explaining 24%-98% of the geographical differences. The educational disparities between LA and the US were associated with gray matter volume and connectivity variations, especially in LA and AD patients. Education emerged as a critical factor in classifying aging and dementia across regions. DISCUSSION: The results underscore the impact of education on brain structure and function in LA, highlighting the importance of incorporating educational factors into diagnosing, care, and prevention, and emphasizing the need for global diversity in research. HIGHLIGHTS: Lower education was linked to reduced brain volume and connectivity in healthy controls (HCs), Alzheimer's disease (AD), and frontotemporal lobar degeneration (FTLD). Latin American cohorts have lower educational levels compared to the those in the United States. Educational disparities majorly drive brain health differences between regions. Educational differences were significant in both conditions, but more in AD than FTLD. Education stands as a critical factor in classifying aging and dementia across regions.

Cervical Pap screening among women living with HIV in Puerto Rico and the United States - Medical Monitoring Project, 2018-2021.

Our objective was to determine the prevalence of cervical Pap screening among women living with HIV (WLWH) in Puerto Rico (P.R.) and other selected United States (U.S.) jurisdictions. Additionally, we sought to compare selected characteristics of WLWH who underwent cervical Pap screening between P.R. and the other U.S. jurisdictions. We analyzed data from the 2018-2021 cycles of CDC's Medical Monitoring Project (MMP), a national surveillance system among adults with HIV residing in P.R. (n = 218) and 22 other MMP jurisdictions (n = 3,653). Weighted percentages and 95 % confidence intervals (CIs) for selected characteristics were estimated. Prevalence ratios with predicted marginal means were calculated. An estimated 91.6 % and 84.6 % of WLWH underwent cervical Pap screening in P.R. and the other 22 MMP jurisdictions, respectively (Prevalence Ratio = 1.08, 95% CI = 1.03-1.13). Among WLWH who underwent cervical Pap screening, those in P.R. were more likely to be 50+ years of age, have a household annual income below $20,000, engage in binge drinking, never smoke, and have Medicaid/other public insurance than those in the other 22 MMP jurisdictions (p < 0.05). No differences were found between P.R. and the other 22 MMP jurisdictions in the percentage reporting higher than the median HIV-stigma score, experiencing HIV health care discrimination, and having ≥ 1 sexual partner in the past 12 months. Although cervical Pap screening rates among WLWH were higher in P.R. than in the other 22 MMP jurisdictions, both surpass the Healthy People 2030 target. Future research should assess adherence and compliance with updated cervical cancer screening guidelines.

Hesitation towards the COVID-19 vaccine in the United States: a digital ethnographic study. / Vacilación ante la vacuna contra el covid-19 en Estados Unidos de América: un estudio etnográfico digital.

Following the authorization the use of COVID-19 vaccines in babies age six months through children four years old in the United States, some individuals (parents, pediatricians, and communicators) framed COVID-19 vaccination as an issue of access, while many others expressed hesitancy and some resisted recommendations from the US Centers for Disease Control and Prevention. In this context, this study aimed to explore: 1) divergent reactions to the authorization of COVID-19 vaccine use in children aged six months to four years; and 2) opposing logics underlying attitudes towards pro-vaccination, anti-vaccination, and vaccine hesitancy regarding COVID-19 vaccines. To achieve this, a digital ethnography was conducted, involving monitoring of 5,700 reactions to a series of eight infographics published on social media by the John Hopkins Bloomberg School of Public Health, and participant observation in an online focus group over a one-year period, from December 2021 to December 2022, consisting of 18 mothers. The findings suggest that healthcare professionals should consider different notions of "risk" when interacting with patients, especially those who are hesitant to vaccinate.

Luego de que se autorizara en EEUU el uso de la vacuna contra el covid-19 en bebés de seis meses a niños y niñas de cuatro años, algunas personas (padres, madres, pediatras y comunicadores) plantearon la vacunación contra el covid-19 como una cuestión de acceso; sin embargo, muchas otras se mostraron reacias y otras se resistieron a las recomendaciones de los Centers for Disease Control and Prevention de EEUU. En este contexto, este estudio se propuso explorar: 1) reacciones divergentes ante la autorización de uso de la vacuna contra el covid-19 en niños y niñas de seis meses a cuatro años; y 2) lógicas contrapuestas que subyacen a las actitudes provacunación, antivacunación y vacilación ante las vacunas contra el covid-19. Para ello, se realizó una etnografía digital, con monitoreo de 5.700 reacciones a una serie de ocho infografías publicadas en las redes sociales por la John Hopkins Bloomberg School of Public Health, y observación participante en un grupo focal en línea a lo largo de un año, desde diciembre de 2021 hasta diciembre de 2022, conformado por 18 madres. Los resultados indican que el personal médico debe considerar diferentes nociones de "riesgo" al interactuar con los pacientes, especialmente aquellos que dudan en vacunarse.

Immigrant-blind care: How immigrants experience the "inclusive" health system as they access care.

A growing body of scholarship examines the varying impact of legal status and race on accessing healthcare. However, a notable gap persists in comprehending the supplementary mechanisms that hinder immigrants' pathway to seek care. Drawing on ethnographic observations in various clinical settings and in-depth interviews with 28 healthcare professionals and 12 documented Haitian immigrants in a city in Upstate New York, between 2019 and 2021, I demonstrate the tension between the conceptualization and implementation of inclusive care practices by healthcare providers. I argue that the mere expansion and adoption of inclusive discourse among providers do not inherently ensure equity and the removal of barriers to healthcare access. This work contributes to the social study of medicine and race and ethnic studies by introducing the innovative concept of "immigrant-blind." Through this concept, the research sheds light on how providers' conceptualization of inclusivity proclaims medical encounters to be devoid of stratifications and rationalizes their practices which mask the profound impact of immigration status and immigration on immigrant health. Furthermore, these practices reinforce existing divisions within care settings and medical encounters, where immigration laws and enforcement practices operate and further exacerbate stratifications. By examining providers' uninformed implementation of culturally competent care practices, the findings reveal that providers stigmatize and essentialize immigrants during medical encounters. This highlights the imperative for a more nuanced and informed approach to healthcare provision, where genuine inclusivity is upheld, and barriers to access are dismantled to foster equitable and dignified healthcare experiences for all.

La Agencia de los Estados Unidos para el Desarrollo Internacional (USAID) como arma contra la colaboración médica internacional de Cuba / United States Agency for International Development (USAID) as a weapon against Cuba's international medical collaboration

El artículo analiza la labor subversiva asignada por la administración de Biden a la Agencia de los Estados Unidos para el Desarrollo Internacional, para atacar a las brigadas médicas cubanas en el exterior. Especialmente, analiza el nuevo programa denominado Combatir el trabajo forzoso en las misiones médicas cubanas, y paralelamente, corrobora la existencia de una estrategia de boicot a la cooperación médica y a la exportación de servicios de salud, sobre todo dirigida a esta última modalidad, con el fin de cortar los ingresos económicos. El antecedente de este nuevo programa es uno similar financiado por el gobierno de Trump, en 2019, aunque este cuenta con 1 millón de dólares adicionales. Como la principal línea de mensaje que se emplea contra los convenios médicos cubanos internacionales, es que violan los derechos humanos al promover el trabajo esclavo, priorizan la búsqueda de testimonios para sustentar dicha campaña. El programa cuenta con elementos propios de acciones encubiertas y exige que los elegidos incidan dentro de Cuba y en países de América Latina. Esto último es consecuente con la estrategia sanitaria que Biden implementa para retomar su influencia en la región, además de restar protagonismo a Cuba. Finalmente, se demuestra que, aunque Biden le impone su impronta a la estrategia, es un continuador de Donald Trump(AU)

The article analyzes the subversive work assigned by the Biden administration to the United States Agency for International Development, to attack Cuban medical brigades abroad. Specifically, it analyzes the new program called Combating forced labor in Cuban medical missions, and at the same time, corroborates the existence of a strategy to boycott medical cooperation and the export of health services, especially aimed at the latter modality, with the in order to cut off economic income. The background to this new program is a similar one funded by the Trump government in 2019, although it has an additional one million dollars. Since the main line of message used against international Cuban medical agreements is that they violate human rights by promoting slave labor, they prioritize the search for testimonies to support said campaign. The program has elements of covert actions and requires those elected to carry out actions within Cuba and in Latin American countries. The latter is consistent with the health strategy that Biden implements to regain his influence in the region, in addition to reducing Cuba's prominence. Finally, it is shown that, although Biden imposes his imprint on the strategy, he is a follower of Donald Trump(AU)

Carbon Material-Reinforced Polymer Composites for Bipolar Plates in Polymer Electrolyte Membrane Fuel Cells.

Bipolar plates (BPs) are one of the most important components of polymer electrolyte membrane fuel cells (PEMFCs) because of their important role in gas and water management, electrical performance, and mechanical stability. Therefore, promising materials for use as BPs should meet several technical targets established by the United States Department of Energy (DOE). Thus far, in the literature, many materials have been reported for possible applications in BPs. Of these, polymer composites reinforced with carbon allotropes are one of the most prominent. Therefore, in this review article, we present the progress and critical analysis on the use of carbon material-reinforced polymer composites as BPs materials in PEMFCs. Based on this review, it is observed that numerous polymer composites reinforced with carbon allotropes have been produced in the literature, and most of the composites synthesized and characterized for their possible application in BPs meet the DOE requirements. However, these composites can still be improved before their use for BPs in PEMFCs.

Blood Pressure Trajectories Through the First Year Postpartum in Overweight or Obese Individuals Following a Hypertensive Disorder of Pregnancy.

BACKGROUND: Hypertensive disorders of pregnancy are associated with cardiovascular disease; however, patterns of blood pressure (BP) recovery are understudied. We compared pregnancy and postpartum BP trajectories among individuals with hypertensive disorders of pregnancy who developed persistent hypertension at 1-year postpartum compared with individuals with normalization of BP. METHODS: We used data from a randomized clinical trial of individuals with overweight, obesity, and hypertensive disorders of pregnancy conducted in the first year after delivery. Pregnancy BPs were obtained during prenatal visits; postpartum BPs were prospectively obtained through home monitoring. Demographic characteristics and trajectories were compared by hypertensive status (systolic BP ≥130 mm Hg, diastolic BP ≥80 mm Hg, or use of antihypertensive medications) at 1 year. We used repeated BP measures to fit separate mixed-effects linear regression models for pregnancy and postpartum using restricted cubic splines. RESULTS: We included 129 individuals; 75 (58%) individuals progressed to hypertension by 1-year postpartum. Individuals with hypertension were older, delivered at earlier gestational ages, and had higher body mass index at 1-year postpartum compared with those with normalization. Individuals with hypertension had similar BP trajectories during pregnancy to those with BP normalization but a significantly different BP trajectory (P<0.01 for systolic and diastolic BPs) in the first year postpartum. These differences persisted in multivariable models after adjustment for early pregnancy body mass index, age, and severity of hypertensive disorder of pregnancy (P<0.01 for systolic and diastolic BPs). CONCLUSIONS: BP trajectories in the first year postpartum, but not during pregnancy, may provide important information for risk stratification after a hypertensive disorder of pregnancy.

Omernik's Ecoregion Framework: a Legacy for Understanding Regional Patterns in Attainable Resource Quality.

An initial and comprehensive map of ecological regions across the conterminous United States was provided by Omernik in 1987. Because that paper was the most-cited published by the Annals of the American Association of Geographers, we sought to assess and quantify its contribution to science. To do so, we conducted a scientometric analysis to address the following main questions: 1) What are the temporal and spatial citation trends? We expected that Omernik's paper would still be employed 36 years after its publication, and mostly in the United States of America. 2) For what types of environments and organisms has it been applied? Based on its generality, we expected that it had been applied to both terrestrial and aquatic ecosystems. 3) What are the main applications of Omernik's article? We predicted that it would mostly be used for describing and delineating study sites and management areas, as well as for selecting regional reference sites. The number of citations presented a positive temporal increase, indicating its continued applicability. Most papers dealt with aquatic environments, mainly in streams carried out predominantly in the United States of America, as was one of its earliest applications. The usefulness of ecoregions for assessing and managing biotic and abiotic patterns and distributions were the main topics addressed by scientists. Ecoregions have offered a general framework for developing regional expectations and rational regional management policies across large areas, as was their original intent. In addition, ecoregion maps were used for communicating patterns-or the lack of them-to interested scientists, citizens, and decision-makers. That comprehensiveness of Omernik's ecoregion approach has led to its widespread applicability and continued usefulness to a diverse set of scientific and management disciplines.

Migração e mortalidade por câncer entre os migrantes colombianos nos EUA: um estudo com dados de declaração de óbito / Migration and cancer mortality among Colombian migrants in the USA: a death certification study

Resumo Este estudo teve como objetivo comparar padrões de mortalidade por câncer entre os imigrantes colombianos nos EUA e colombianos em sua terra natal. Dados de 2008 a 2012 foram coletados, e foram calculadas taxas de mortalidade por câncer de colombianos residindo em seu país natal e colombianos residindo em Califórnia, Flórida e Nova York, bem como taxas específicas de mortalidade por idade e sexo por cada 100.000 pessoas. Para comparar as duas populações, tanto antes como após a correção pela escolaridade, as razões de taxas de mortalidade (MRR) foram estimadas por modelo de regressão binomial negativa. Foi descoberto que colombianos em sua terra natal apresentam taxas de mortalidade por câncer mais altas quando comparados aos que residem nos EUA (MRR masculino 1,4 (IC 95%: 1,2-1,5), MRR feminino 1,5 (IC 95%: 1,3-1,7)). Essas diferenças persistem para a maioria dos tipos de câncer, mesmo após correção pela escolaridade. Os colombianos em sua terra natal apresentaram taxa de mortalidade por câncer gástrico (MRR masculino 2,6; feminino 2,8) e cervical (MRR 5,0) significativamente mais alta em comparação com os que residem nos EUA. As desigualdades educacionais na mortalidade por câncer foram mais acentuadas para aqueles que moram em sua terra natal. A menor taxa de mortalidade por câncer observada entre os colombianos nos EUA, porém, não pode ser atribuída às diferenças de escolaridade, um indicador de status socioeconômico. Em vez disso, provavelmente ocorre devido à maior acessibilidade aos serviços de saúde preventivos e curativos nos EUA.

Abstract We aim to compare cancer mortality rates of USA Colombian migrants (USA Colombians) to Colombians in their country of origin (CO Colombians). Using Colombian national mortality data and data on cancer deaths among Colombians residing in the states of California, Florida, and New York (USA Colombians) for the period 2008-2012, we estimated sex-specific and age-standardized mortality rates (ASMR), expressed per 100,000 persons. For comparisons between the two populations before and after adjustment for educational level, negative binomial regression models were used to compute Mortality Rate Ratios (MRR). CO Colombians had higher cancer mortality rates compared with USA Colombians (male MRR 1.4 [95%CI: 1.2-1.5], female MRR 1.5 [95%CI: 1.3-1.7]). These differences persisted for most cancers even after adjustment for education. CO Colombians had significantly higher mortality from gastric (MRR 2.6 in males and 2.8 in females) and cervical cancer (MRR 5.0) compared with US Colombians. Educational inequalities in cancer mortality were more pronounced among CO Colombians than among USA Colombians. Lower cancer mortality observed among USA Colombians cannot be attributed to differences in education, an indicator of socio-economic status. Rather, it is likely due to better access to preventive and curative healthcare in the USA.

Genomic Diversity and Zoonotic Potential of Brucella neotomae.

After reports in 2017 of Brucella neotomae infections among humans in Costa Rica, we sequenced 12 strains isolated from rodents during 1955-1964 from Utah, USA. We observed an exact strain match between the human isolates and 1 Utah isolate. Independent confirmation is required to clarify B. neotomae zoonotic potential.

El orden de nacimiento como factor de riesgo para ser víctima de trata sexual en el triángulo norte de Centroamérica / Birth order as a risk factor for being victim of sex trafficking in the northern triangle of Central America

RESUMEN Las redes de tráfico humano para la prostitución captan a menores vulnerables, en especial, a quienes consideran no les queda otra opción que emigrar al norte para hacer frente a problemas económicos graves. El objetivo del presente trabajo fue establecer si el orden de nacimiento representó un factor de riesgo, asociado a la vulnerabilidad para la trata sexual de menores centroamericanas, traficadas a Estados Unidos. Las entrevistadas mostraban vulnerabilidades vinculadas con estructuras sociales y conductas individuales. Por una parte, todas crecieron en hogares caracterizados por la pobreza extrema. Por otra parte, también presentaban vulnerabilidades relacionadas con el embarazo adolescente, la falta de educación, la disfuncionalidad familiar y la participación en mercados ilegales. Ocupar el primer lugar en orden de nacimiento eleva la vulnerabilidad de las menores a ser traficadas a Estados Unidos para el comercio sexual. Por el contrario, ocupar el último lugar disminuye este riesgo.

ABSTRACT Human trafficking networks for prostitution recruit vulnerable underage girls, especially those who are considered with no choice but to migrate north to cope with serious economic problems. The aim of this work was to determine if birth order represented a risk factor associated to the vulnerability for sex trafficking of Central American female minors. The interviewees presented vulnerabilities associated to social structures and individual behaviors. On the one hand, all of them grew up in house holds characterized by extreme poverty. On the other hand, they also had vulnerabilities related to teenage pregnancy, lack of education, family dysfunction and participation in illegal markets. Findings suggest that occupying the first place in the order of birth raises the vulnerability of minors to being trafficked to the United States for sex trade. On the contrary, occupying the last place decreases this risk.

Abortion access in the Americas: a hemispheric and historical approach.

This perspective article situates the 2022 United States (U.S.) Supreme Court's overturning of Roe v. Wade (1973) within the broader history of abortion rights activism and legislation in the greater Americas. The U.S. public has stereotyped Latin America and the Caribbean (LAC) as socially conservative regarding gender issues and anti-reproductive rights. But twenty-first-century LAC presents a more complicated landscape than this dominant narrative suggests. In the past 15 years, political, legislative, and public health advances and setbacks across the region provide both a blueprint for re-establishing access to safe and legal abortion and a warning on the consequences of the criminalization of abortion for the U.S. Employing a narrative approach that summarizes recent interdisciplinary literature, this perspective traces the history of the expansion of abortion access in the Americas. Mexico (2007, 2023), Uruguay (2012), Argentina (2020), and Colombia (2022) legalized abortion on demand within specific timeframes. These expansions coexist with severe restrictions on abortion in various nations including Haiti (1835), the Dominican Republic (1884, 2009), Honduras (1985, 2021), El Salvador (1997), and Nicaragua (2006), as well as some states in the United States (2022). This perspective finds that legalization occurs when feminist activists eschew U.S.-based feminist rhetoric of individual rights and choice to reframe abortion as a form of gender-based violence within a discourse of health and wellbeing as a human right. According to this perspective, restrictions on access to the procedure constitute a form of violence against women and people capable of bearing children and violate human rights.

Cross-cultural measurement invariance evidence of individualism and collectivism: from the idiosyncratic to universal.

Introduction: Culture plays a fundamental role in shaping human behavior, with individualism and collectivism being key cultural dimensions. However, existing scales for measuring these constructs, such as the INDCOL scale, have demonstrated issues when applied in diverse cultural contexts. To address this, we present the translation and adaptation of the Mexican Vertical and Horizontal Individualism and Collectivism Scale (MXINDCOL) into English, aiming to identify both universal and culture-specific elements. Methods: Data were collected from 1124 participants (371 from the United States, 753 from Mexico) using the MXINDCOL and INDCOL scales. Propensity score matching was applied to balance demographic differences between the samples. Confirmatory Factor Analysis (CFA) assessed model fit, and cross-cultural measurement invariance was examined. Reliability, convergent and discriminant validity were also assessed. Results: The English-translated MXINDCOL scale demonstrated good model fit in both US and Mexican samples, outperforming the INDCOL scale. Reliability values were higher for the MXINDCOL scale compared to INDCOL. Cross-cultural measurement invariance was established, allowing for meaningful comparisons between the two cultures. US participants scored higher on vertical collectivism, while Mexican participants scored higher on horizontal collectivism and horizontal individualism. Discussion: The MXINDCOL scale offers a culturally sensitive measurement of individualism and collectivism, addressing issues found in existing scales. It provides a more accurate assessment of cultural orientations and enriches the understanding of cultural dimensions by incorporating idiosyncratic elements. Further research in diverse cultural contexts is recommended to validate and refine the scale, contributing to a more nuanced understanding of cultural variations in individualism and collectivism.

Generic cardiology drug prices: the potential benefits of the Marc Cuban cost plus drug company model.

Introduction: Generic pharmaceuticals account for the majority of the $359 billion US pharmaceutical market, including for cardiology drugs. Amidst a lack of price transparency and administrative inefficiencies, generic drug prices are high, causing an undue burden on patients. Methods: We identified the 50 most used generic cardiology drugs by volume per the 2020 Medicare Part D spending data. We extracted cost per dose of each drug from the Marc Cuban Cost Plus Drug Company (MCCPDC) website and estimated the aggregate cost savings if MCCPDC were employed on a national scale by calculating the difference between this cost and Medicare spending. Results: Medicare spent $7.7 billion on the 50 most used generic cardiology drugs by volume in 2020 according to Medicare Part D data. Pharmacy and shipping costs accounted for a substantial portion of expenditures. Per our most conservative estimate, $1.3 billion (17% of total) savings were available on 16 of 50 drugs. A slightly less conservative estimate suggested $2.9 billion (38%) savings for 35 of 50 drugs. Discussion: There is enormous potential for cost savings in the US market for generic cardiology drugs. By encouraging increased competition, decreasing administrative costs, and advocating for our patients to compare prices between the MCCPDC and other generic pharmaceutical dispensers, we have the potential to improve access to care and corresponding outcomes for cardiology patients.

Update on Outbreak of Fungal Meningitis among U.S. Residents who Received Epidural Anesthesia at Two Clinics in Matamoros, Mexico.

BACKGROUND: Public health officials are responding to an outbreak of fungal meningitis among patients who received procedures under epidural anesthesia at two clinics (River Side Surgical Center and Clinica K-3) in Matamoros, Mexico, during January 1-May 13, 2023. This report describes outbreak epidemiology and outlines interim diagnostic and treatment recommendations. METHODS: Interim recommendations for diagnosis and management were developed by the Mycoses Study Group Research Education and Consortium (MSGERC) based on the clinical experience of clinicians caring for patients during the current outbreak or during previous outbreaks of healthcare-associated fungal meningitis in Durango, Mexico, and the United States. RESULTS: As of July 7, 2023, the situation has evolved into a multistate and multinational fungal meningitis outbreak. A total of 185 residents in 22 U.S. states and jurisdictions have been identified who might be at risk of fungal meningitis because they received epidural anesthesia at the clinics of interest in 2023. Among these patients, 11 suspected, 10 probable, and 10 confirmed U.S. cases have been diagnosed, with severe vascular complications and eight deaths occurring. Fusarium solani species complex has been identified as the causative agent, with antifungal susceptibility testing of a single isolate demonstrating poor in vitro activity for most available antifungals. Currently, triple therapy with intravenous voriconazole, liposomal amphotericin B, and fosmanogepix is recommended. CONCLUSIONS: Efforts to understand the source of this outbreak and optimal treatment approaches are ongoing, but infectious diseases physicians should be aware of available treatment recommendations. New information will be available on CDC's website.

Trends in Routine Checkup Within the Past Year Following a Hurricane.

The goal of this nationally representative, cross-sectional study is to evaluate the trends in routine checkup within the last year associated with exposure to a hurricane. We compared Puerto Rico (2017 Hurricane Irma, Hurricane Maria), Texas (2017 Hurricane Harvey), and Florida (2017 Hurricane Irma, Hurricane 2018 Michael) with states that had a category 1-2 hurricane make landfall from 2014 to 2019: Georgia, Louisiana, Mississippi, North Carolina, and South Carolina. We found that states impacted by a major hurricane in 2017 had a drop in routine checkup while the states that experienced a category 1-2 landfall did have a change in that year. By the following year, all states reported an increase in routine checkup suggesting that the disruption in routine care was temporary.

The Implementation of CDC COVID-19 Recommendations for Testing, Isolation, Quarantine and Movement at Emergency Intake Sites of Unaccompanied Children in the United States, April 1-May 31, 2021.

In March 2021, Emergency Intake Sites (EIS) were created to address capacity shortfalls during a surge of Unaccompanied Children at the Mexico-United States land border. The COVID-19 Zone Plan (ZP) was developed to decrease COVID-19 transmission. COVID-19 cumulative percent (%) positivity was analyzed to evaluate the impact of the ZP, venue type and bed capacity across EIS from April 1-May 31, 2021. Results: Of 11 EIS sites analyzed, 54% implemented the recommended ZP. The overall % positivity was 2.47% (95% CI 2.39-2.55). The % positivity at EIS with the ZP, 1.83% (95% CI 1.71-1.95), was lower than that at EIS without the ZP, 2.83%, ( 95% CI 2.72-2.93), and showed a lower 7-day moving average of % positivity. Conclusion: Results showed a possible effect of the ZP on % positivity when controlling for venue type and bed capacity in a specific EIS group comparison, indicating that all three variables could have had effect on % positivity. They also showed that smaller intake facilities may be recommendable during public health emergencies.

Comparison of Climate Change Scenarios of Rhipicephalus sanguineus sensu lato (Latreille 1806) from México and the Boarders with Central America and the United States.

In America, the presence of Rhipicephalus sanguineus sensu stricto and Rhipicephalus linnaei has been confirmed. Both species are found in sympatry in the southern United States, northern Mexico, southern Brazil, and Argentina. The objective of this work is to evaluate the projection of the potential distribution of the ecological niche of Rhipicephalus sanguineus sensu lato in two climate change scenarios in Mexico and the border with Central America and the United States. Initially, a database of personal collections of the authors, GBIF, Institute of Epidemiological Diagnosis and Reference, and scientific articles was built. The ENMs were projected for the current period and two future scenarios: RCP and SSP used for the kuenm R package, the ecological niche of R. sanguineus s.l. It is distributed throughout the Mexico and Texas (United States), along with the border areas between Central America, Mexico, and the United States. Finally, it is observed that the ecological niche of R. sanguineus s.l. in the current period coincides in three degrees with the routes of human migration. Based on this information, and mainly on the flow of migrants from Central America to the United States, the risk of a greater gene flow in this area increases, so the risk relating to this border is a latent point that must be analyzed.

Adolescents de facto deported in Oaxaca, Mexico: Mental and emotional health impacts.

This paper examines the experiences of adolescents from mixed migratory status families affected by deportation. We analyze the impacts on their mental and emotional health when they are separated from one parent in the United States, forcibly displaced with another to Oaxaca, and experience the consequences of their deportation in Mexico. We use a qualitative and ethnographic methodology. This paper focuses on data from semi-structured interviews and focus groups with 15 parents who had been deported from the United States and 53 adolescents who moved with them to Mexico. The data was collected between 2018 and 2020. The main findings show the existence of emotions that are sustained in the transnational flow and acquire new nuances upon return. They also show the emergence of new conditions related to family separation, all of which have an impact on the adolescents' well-being and on important areas of their lives, such as education. The research contributes to knowledge in two main ways: 1) it addresses the impacts of parental deportation on the well-being of adolescents in mixed-status families, which have typically focused on children; 2) it studies how parental deportation affects the mental and emotional health of adolescents de facto deported to Mexico, a field still little studied.

Marketing authorisation and pricing of FDA-approved cancer drugs in Brazil: a retrospective analysis.

Background: Most cancer drugs enter the US market first. US Food and Drug Administration (FDA) approvals of new cancer drugs may influence regulatory decisions in other settings. The study examined whether characteristics of available evidence at FDA approval influenced time-to-marketing authorisation (MA) in Brazil, and price differences between the two countries. Methods: All new FDA-approved cancer drugs from 2010 to 2019 were matched to drugs with MA and prices approved in Brazil by December 2020. Characteristics of main studies, availability of randomised controlled trials (RCTs), overall survival (OS) benefit, added therapeutic benefit, and prices were compared. Findings: Fifty-six FDA-approved cancer drugs with matching indications received a MA at the Brazilian Health Regulatory Agency (Anvisa) after a median of 522 days following US approval (IQR: 351-932). Earlier authorisation in Brazil was associated with availability of RCT (median: 506 vs 760 days, p = 0.031) and evidence of OS benefit (390 vs 543 days, p = 0.019) at FDA approval. At Brazilian marketing authorisation, a greater proportion of cancer drugs had main RCTs (75% vs 60.7%) and OS benefit (42.9% vs 21.4%) than that in the US. Twenty-eight (50%) drugs did not demonstrate added therapeutic benefit over drugs for the same indication in Brazil. Median approved prices of new cancer drugs were 12.9% lower in Brazil compared to the US (adjusted by Purchasing Power Parity). However, for drugs with added therapeutic benefit median prices were 5.9% higher in Brazil compared to the US, while 17.9% lower for those without added benefit. Interpretation: High-quality clinical evidence accelerated the availability of cancer medicines in Brazil. The combination of marketing and pricing authorisation in Brazil may favour the approval of cancer drugs with better supporting evidence, and more meaningful clinical benefit albeit with variable degree of success in achieving lower prices compared to the US. Funding: None.
