The Impact of Colonialism on Surgical Training Structures in Africa Part 1: Contextualizing the Past, Present, and Future.

Since the first African country attained independence from colonial rule, surgical training on the continent has evolved along 3 principal models. The first is a colonial, local master-apprentice model, the second is a purely local training model, and the third is a collegiate intercountry model. The 3 models exist currently and there are varied perceptions of their relative merits in training competent neurosurgeons. We reviewed the historical development of training and in an accompanying study, seek to describe the complex array of surgical training pathways and explore the neocolonial underpinnings of how these various models of training impact today the development of surgical capacity in Africa. In addition, we sought to better understand how some training systems may contribute to the widely recognized "brain drain" of surgeons from the African continent to high income countries in Europe and North America. To date, there are no published studies evaluating the impact of surgical training systems on skilled workforce emigration out of Africa. This review aims to discover potentially addressable sources of improving healthcare and training equity in this region.

The Migration of Lynch Victims' Families, 1880-1930.

We examine the relationship between the lynching of African Americans in the southern United States and subsequent county out-migration of the victims' surviving family members. Using U.S. census records and machine learning methods, we identify the place of residence for family members of Black individuals who were killed by lynch mobs between 1882 and 1929 in the U.S. South. Over the entire period, our analysis finds that lynch victims' family members experienced a 10-percentage-point increase in the probability of migrating to a different county by the next decennial census relative to their same-race neighbors. We also find that surviving family members had a 12-percentage-point increase in the probability of county out-migration compared with their neighbors when the household head was a lynch victim. The out-migration response of the families of lynch victims was most pronounced between 1910 and 1930, suggesting that lynch victims' family members may have been disproportionately represented in the first Great Migration.

This study examines sexual assault allegations perpetrated against individuals detained across US Immigration and Customs Enforcement (ICE) detention facilities from 2018 to 2022.

Probabilistic forecasts of international bilateral migration flows.

We propose a method for forecasting global human migration flows. A Bayesian hierarchical model is used to make probabilistic projections of the 39,800 bilateral migration flows among the 200 most populous countries. We generate out-of-sample forecasts for all bilateral flows for the 2015 to 2020 period, using models fitted to bilateral migration flows for five 5-y periods from 1990 to 1995 through 2010 to 2015. We find that the model produces well-calibrated out-of-sample forecasts of bilateral flows, as well as total country-level inflows, outflows, and net flows. The mean absolute error decreased by 61% using our method, compared to a leading model of international migration. Out-of-sample analysis indicated that simple methods for forecasting migration flows offered accurate projections of bilateral migration flows in the near term. Our method matched or improved on the out-of-sample performance using these simple deterministic alternatives, while also accurately assessing uncertainty. We integrate the migration flow forecasting model into a fully probabilistic population projection model to generate bilateral migration flow forecasts by age and sex for all flows from 2020 to 2025 through 2040 to 2045.

Evaluation and analysis on suitability of human settlement environment in Qingdao.

Human settlement environment is space places closely related to human production and life, and also surface spaces inseparable from human activities. As a coastal city in the east of China, Qingdao has a relatively high level of urbanization. However, it also along with many urban problems at the same time, among which the problem of human settlement environment has attracted more and more general attention from people. According to the characteristics of human settlement environment in Qingdao, the research constructs an index system with 10 index factors from natural factors and humanity factors, and proposes a comprehensive evaluation model. Evaluate and grade suitability of human settlement environment in Qingdao, explore the spatial aggregation and differentiation of the quality of human settlement environment, and reveal the internal connection of spatial evolution. The results indicate that the overall livability of Qingdao is relatively good, showing a multi-center and radial driving development. The distribution of livability is uneven, showing a decreasing spatial distribution law from the coast to the inland, and the quality of human settlement environment in Jiaozhou Bay and the coastal areas is relatively high. Qingdao is mainly based on natural livability, supplemented by humanity livability, compared with natural suitability, the spatio-temporal evolution characteristics of humanity livability have experienced three stages: rising-contradictory rising-harmonious rising. The quality of human settlement environment has obvious spatial correlation and is positively correlated with the degree of agglomeration, and the agglomeration of blocks with a higher quality of human settlement environment is higher than that of blocks with a lower level. The rule of human settlement environment changing over time is that areas with high quality of human settlement environment begin to shift from the city center to the north and the south, transforming into multi-point development, and overall environmental suitability has been improved. According to the results of the comprehensive evaluation, combined with its local development status and policies, the research puts forward developmental suggestions for the construction of human settlement environment in Qingdao, and provides decision-making basis for relevant departments to solve the problem of deterioration of human settlement environment.

International migration of unaccompanied minors: trends, health risks, and legal protection.

The global population of unaccompanied minors-children and adolescents younger than 18 years who migrate without their legal guardians-is increasing. However, as data are not systematically collected in any region, if collected at all, little is known about this diverse group of young people. Compared with adult migrants, unaccompanied minors are at greater risk of harm to their health and integrity because they do not have the protection provided by a family, which can affect their short-term and long-term health. This Review summarises evidence regarding the international migration and health of unaccompanied minors. Unaccompanied minors are entitled to protection that should follow their best interests as a primary consideration; however, detention, sometimes under the guise of protection, is a widespread practice. If these minors are provided with appropriate forms of protection, including health and psychosocial care, they can thrive and have good long-term outcomes. Instead, hostile immigration practices persist, which are not in the best interests of the child.

Assessment of COVID-19-Related Immigration Concerns Among Latinx Immigrants in the US.

Importance: Despite the contentious immigration environment and disproportionate rates of COVID-19 infection among Latinx individuals in the US, immigrants' concerns about engaging in COVID-19-related testing, treatment, and contact tracing have been largely unexplored. Objective: To examine the proportions of Latinx immigrants who endorse statements about the potential negative immigration ramifications of seeking and using COVID-19-related testing and treatment services and engaging in contact tracing. Design, Setting, and Participants: In this cross-sectional survey study, 25 COVID-19-related items were incorporated into the online Spanish-language survey of an ongoing study. Data were collected between July 15 and October 9, 2020, in Chicago, Illinois; Los Angeles, California; and Phoenix, Arizona. A nonrandom sample of 379 adult, Spanish-speaking, noncitizen Latinx immigrants (with either documented or undocumented immigration status) were sent surveys. Of those, 336 individuals (88.7% participation rate) returned surveys, and 43 individuals did not. An additional 213 individuals were screened but ineligible. Descriptive statistics were computed, and mean comparisons and bivariate correlations between sociodemographic variables, indices of immigration risk, and COVID-19-related survey items were conducted. Main Outcomes and Measures: Items elicited agreement or disagreement with statements about immigrants' access to COVID-19-related testing and treatment services and the potential immigration ramifications of using these services. Willingness to identify an undocumented person during contact tracing was also assessed. Results: A total of 336 Latinx immigrants completed surveys. The mean (SD) age of participants was 39.7 (8.9) years; 210 participants (62.5%) identified as female, and 216 participants (64.3%) had undocumented immigration status. In total, 89 participants (26.5%) agreed that hospital emergency departments were the only source of COVID-19 testing or treatment for uninsured immigrants, and 106 participants (31.6%) agreed that using public testing and health care services for COVID-19 could jeopardize one's immigration prospects. A total of 96 participants (28.6%) and 114 participants (33.9%), respectively, would not identify an undocumented household member or coworker during contact tracing. Reluctance to identify an undocumented household member or coworker was associated with having had deportation experiences (r = -0.17; 95% CI, -0.06 to 0.27; P = .003) but not with the number of years lived in the US (r = 0.07; 95% CI, -0.16 to 0.17; P = .15) or immigration status (r = 0.03; 95% CI, -0.07 to 0.13; P = .56). Conclusions and Relevance: In this cross-sectional survey study, a substantial number of immigrants endorsed statements about immigrants' restricted access to COVID-19-related testing and treatment services and the potential negative immigration ramifications of using these services. These results suggest that programs for COVID-19-related testing, contact tracing, and vaccine administration that are designed to allay immigration concerns are needed.

The persistence of ancient settlements and urban sustainability.

We propose a dedicated research effort on the determinants of settlement persistence in the ancient world, with the potential to significantly advance the scientific understanding of urban sustainability today. Settlements (cities, towns, villages) are locations with two key attributes: They frame human interactions and activities in space, and they are where people dwell or live. Sustainability, in this case, focuses on the capacity of structures and functions of a settlement system (geography, demography, institutions) to provide for continuity of safe habitation. The 7,000-y-old experience of urbanism, as revealed by archaeology and history, includes many instances of settlements and settlement systems enduring, adapting to, or generating environmental, institutional, and technological changes. The field of urban sustainability lacks a firm scientific foundation for understanding the long durée, relying instead on narratives of collapse informed by limited case studies. We argue for the development of a new interdisciplinary research effort to establish scientific understanding of settlement and settlement system persistence. Such an effort would build upon the many fields that study human settlements to develop new theories and databases from the extensive documentation of ancient and premodern urban systems. A scientific foundation will generate novel insights to advance the field of urban sustainability.

Four Athenas - Europe's first female neurosurgeons.

In the early 20th century, a tumultuous era was yielding geopolitical and social change. Europe at large was undergoing redefinition of borders, political structures, and economies, while rebuilding societies after World War I. At the same time, neurosurgery was emerging as a new specialty, and women were allowed to study medicine for the first time in many European countries. These factors created a synergy, setting the stage for Europe's four first female neurosurgeons to emerge. In 1924, Germany's Alice Rosenstein began her neurosurgical career and contributed to the refinement of pneumoencephalography. Due to her Jewish background, she was forced to flee Europe, emigrating to the United States, where she did not continue to practice neurosurgery. In 1929, Russia's Serafima Bryusova began her neurosurgical training. She studied intracranial pressure in trephined patients and wrote the first Russian monograph on cerebral angiography before she was immobilized by severe arthritis. England's Diana Beck began her neurosurgical career in 1939. She contributed to the surgical treatment of intracerebral hemorrhage and researched idiopathic intracranial hypertension, even though many believed she could not be a successful surgeon due to her myasthenia gravis. In 1943, Romania's Sofia Ionescu started a prolific academic neurosurgical career. She developed a minimally-invasive technique to treat intracerebral hematomas and worked tirelessly to bring neurosurgery to all corners of her country. Europe's first women in neurosurgery were marked by war and adversity. Their stories carry within them a spirit of resilience, fortitude, and tenacity that continues to characterize women in neurosurgery today.

Health Care Use Among Latinx Children After 2017 Executive Actions on Immigration.

BACKGROUND: US immigration policy changes may affect health care use among Latinx children. We hypothesized that January 2017 restrictive immigration executive actions would lead to decreased health care use among Latinx children. METHODS: We used controlled interrupted time series to estimate the effect of executive actions on outpatient cancellation or no-show rates from October 2016 to March 2017 ("immigration action period") among Latinx children in 4 health care systems in North Carolina. We included control groups of (1) non-Latinx children and (2) Latinx children from the same period in the previous year ("control period") to account for natural trends such as seasonality. RESULTS: In the immigration action period, 114 627 children contributed 314 092 appointments. In the control period, 107 657 children contributed 295 993 appointments. Relative to the control period, there was an immediate 5.7% (95% confidence interval [CI]: 0.40%-10.9%) decrease in cancellation rates among all Latinx children, but no sustained change in trend of cancellations and no change in no-show rates after executive immigration actions. Among uninsured Latinx children, there was an immediate 12.7% (95% CI: 2.3%-23.1%) decrease in cancellations; however, cancellations then increased by 2.4% (95% CI: 0.89%-3.9%) per week after immigration actions, an absolute increase of 15.5 cancellations per 100 appointments made. CONCLUSIONS: There was a sustained increase in cancellations among uninsured Latinx children after immigration actions, suggesting decreased health care use among uninsured Latinx children. Continued monitoring of effects of immigration policy on child health is needed, along with measures to ensure that all children receive necessary health care.

Indian medical graduates in New Zealand: does anyone win?

Medical migration has become a global phenomenon, partly led by easier air travel, economic factors and the expansion of medical technology. New Zealand has gradually evolved from being 'bicultural' to a multicultural, multitextured society. The movement of the Indian people, particularly Indian physicians, will be the focus of this paper. In the last three decades, migration eligibility in New Zealand has changed from countries of origin or ability to speak English, to profession and skills. Despite struggling with its own issues, New Zealand has proven to be a preferred destination for Indian medical graduates (IMGs). India is widely recognised as the largest 'donor country' for doctors, many of whom go on to establish themselves as leaders and prominent figures in their field. This migration involves three parties: India as a donor country, New Zealand as a recipient country and IMGs as the drivers of this process. Factors behind this growing phenomenon are examined and recommendations are made so that all three parties can benefit from it.

A Meta-Synthesis of Policy Recommendations Regarding Human Mobility in the Context of Climate Change.

Changing mobility patterns combined with changes in the climate present challenges and opportunities for global health, requiring effective, relevant, and humane policy responses. This study used data from a systematic literature review that examined the intersection between climate change, migration, and health. The study aimed to synthesize policy recommendations in the peer-reviewed literature, regarding this type of environmental migration with respect to health, to strengthen the evidence-base. Systematic searches were conducted in four academic databases (PubMed, Ovid Medline, Global Health and Scopus) and Google Scholar for empirical studies published between 1990-2020 that used any study design to investigate migration and health in the context of climate change. Studies underwent a two-stage protocol-based screening process and eligible studies were appraised for quality using a standardized mixed-methods tool. From the initial 2425 hits, 68 articles were appraised for quality and included in the synthesis. Among the policy recommendations, six themes were discernible: (1) avoid the universal promotion of migration as an adaptive response to climate risk; (2) preserve cultural and social ties of mobile populations; (3) enable the participation of migrants in decision-making in sites of relocation and resettlement; (4) strengthen health systems and reduce barriers for migrant access to health care; (5) support and promote optimization of social determinants of migrant health; (6) integrate health into loss and damage assessments related to climate change, and consider immobile and trapped populations. The results call for transformative policies that support the health and wellbeing of people engaging in or affected by mobility responses, including those whose migration decisions and experiences are influenced by climate change, and to establish and develop inclusive migrant healthcare.

Neighborhood Context and Drug Use Among Mexican Americans on and off the U.S.-Mexico Border.

OBJECTIVE: Prior research has suggested that drug use rates may be high at the U.S.-Mexico border, but in more recent research rates varied significantly between border communities. This study reports findings on the mediating influence of neighborhood-level variables on the observed difference in past-year drug use rates between two border sites and an interior site, focusing on Mexican Americans. METHOD: Data were analyzed from the U.S.-Mexico Study on Alcohol and Related Conditions (UMSARC) on 1,345 Mexican-origin respondents ages 18-40 from the border sites of Laredo and Brownsville/McAllen compared with the nonborder site of San Antonio, separately for men and women. Neighborhood-level variables (based on census tracts and block groups) included drug availability, neighborhood insecurity, crime victimization, crime witnessing, off-premise alcohol outlet density, on-premise alcohol outlet density, percentage crossing the border more than 100 times, neighborhood disadvantage, residential stability, and percentage of White/non-Hispanic. RESULTS: When individual sociodemographic characteristics were controlled for, lower drug use among men in Brownsville/McAllen (vs. San Antonio) was partially mediated by lower drug availability and lower perceived neighborhood insecurity whereas increased drug use among women in both Laredo and Brownsville/McAllen was partially mediated by the lower proportion of White/non-Hispanic residents compared with San Antonio. CONCLUSIONS: Neighborhood-level variables partially explain the heterogeneity in drug use across sites at the U.S.-Mexico border, but different factors appear to be operating for men compared with women. These findings suggest the potential importance of addressing neighborhood factors in reducing drug-related harm at the U.S.-Mexico border.
