Some phenomena of the cap-pushing response in honey bees (Apis mellifera spp.).

The cap-pushing response (CPR) is a new free-flying technique used to study learning and memory in honey bees. Bees fly to a target where they push a cap to reveal a hidden food source. When combined with traditional odor and color targets, the CPR technique opens the door to additional choice preference tests in honey bees. To facilitate the use of the CPR technique, three experiments were conducted. Experiment 1 investigates the impact of extended training on the CPR response and its role in extinction. Experiment 2 explores the role of CPR in overshadowing, and Experiment 3 explores the effects of electric shock punishment on the CPR technique.

Migration as a Vector of Economic Losses From Disaster-Affected Areas in the United States.

We introduce the consideration of human migration into research on economic losses from extreme weather disasters. Taking a comparative case study approach and using data from the Federal Reserve Bank of New York/Equifax Consumer Credit Panel, we document the size of economic losses attributable to migration from 23 disaster-affected areas in the United States before, during, and after some of the most costly hurricanes, tornadoes, and wildfires on record. We then employ demographic standardization and decomposition to determine if these losses primarily reflect changes in out-migration or the economic resources that migrants take with them. Finally, we consider the implications of these losses for changing spatial inequality in the United States. While disaster-affected areas and their populations differ in their experiences of and responses to extreme weather disasters, we generally find that, relative to the year before an extreme weather disaster, economic losses via migration from disaster-affected areas increase the year of and after the disaster, these changes primarily reflect changes in out-migration (vs. the economic resources that migrants take with them), and these losses briefly disrupt the status quo by temporarily reducing spatial inequality.

The Aortic Dissection Collaborative: Methods for building capacity for patient-centered outcomes research in the aortic dissection community.

Understanding what matters most to patients can help guide research in a direction that is best situated to provide evidence that is responsive to their core concerns. This can better inform the treatment decision-making process for patients and their physicians. The Aortic Dissection (AD) Collaborative built a collaborative AD research infrastructure involving patients and other stakeholders to facilitate patient-centered outcomes research training, support, and networking among those affected by AD. Two surveys and semi-structured interviews were conducted between January and October 2020 to gather information from people with and at risk for AD and their family members to better understand their experiences and needs. Discussion of survey and interview results were then articulated as seven key topics for future research to meet the needs of the AD community. Working groups were assembled to address each of the key topics. The groups conducted landscape reviews that were focused on providing guidance for future research that directly addresses the needs identified by the AD community. Recommendations for future research generated by the working groups were compiled by the Aortic Dissection Collaborative. From these recommendations, the Aortic Dissection Collaborative advisors and stakeholders identified high-priority research questions. The research questions form the basis for a third survey, disseminated to the Virtual Research Network between November 2021 and February 2022. Final analysis of the survey will identify top ranked research questions and assess willingness to participate. These results will inform the development of future patient-centered outcomes research and comparative effectiveness research proposals.

User Beware: Concerning Findings from the Post 2011-2012 U.S. Internal Revenue Service Migration Data.

The U.S. Internal Revenue Service (IRS) makes publicly and freely available period migration data at the state and county levels. Among their uses, these data inform estimates of net-migration as part of the U.S. Census Bureau's Population Estimates Program, which, in turn, are used for producing other annual statistics, survey design, business and community planning, and federal funding allocations. Building on and extending prior research, we devote this Research Brief to documenting from multiple new angles a highly concerning and apparently systemic problem with the IRS migration data since the IRS took over responsibilities for preparing these data from the U.S. Census Bureau in 2011. As we then discuss, despite the fact that the IRS provides documentation detailing changes that it made to how it prepares these data relative to how the U.S. Census Bureau prepared them, it is not clear why or how these changes would result in the problem detailed in our analysis. Given that this problem appears to be an internal one within the IRS, we conclude by suggesting that the post 2011-12 IRS migration data not be used until this problem is resolved, and we encourage the IRS to do so quickly, transparently, and collaboratively.

An approach on the migratory processes in the north of Chile based on Y chromosome analysis.

OBJECTIVES: Northern Chile is an area characterized by a complex cultural and demographic trajectory. During the last few centuries, this complex trajectory has become the destination of intra- and intercontinental migratory waves. In this study, we analyzed the Y chromosome to evaluate how migratory and admixture patterns have affected the genetic composition of the populations in northern Chile compared with other populations of the country. METHODS: A total of 311 people from urban (Antofagasta and Calama), rural (Azapa and Camarones), and Native (Aymara and Atacameño) populations from northern Chile were characterized by 26 SNPs and the STR DYS393 of the Y chromosome, along with 69 individuals from Native populations (Mapuche, Pehuenche, and Huilliche) from southern Chile. In addition to characterizing the paternal lineages, multivariate analyses were performed to compare with published data from other Chilean populations. RESULTS: Both the Antofagasta and Calama populations show differences compared with the rest of the Chilean population. On one side, Antofagasta shows a high diversity of non-Amerindian lineages, including the highest value for haplogroup I (12%) for all Chileans populations. Otherwise, Calama has the highest value of any Chilean urban population (31.9%) for Amerindian lineages, including the only Q-M3 sub-lineage detected in the entire sample. Regarding the Native population, Aymara presents the highest percentage of Q-M3 (94.4%). CONCLUSIONS: The Y chromosome haplogroup distribution allowed us to identify recent migratory processes typical of the northern populations studied. These have shaped the demographic and cultural dynamics of local and migrant groups in the territory.

Ancestry and admixture of a southernmost Chilean population: The reflection of a migratory history.

OBJECTIVES: Punta Arenas is a Chilean city situated on ancestral Aönikenk territory. The city was founded by 19th- and 20th-century colonists from Chile (Chiloé) and Europe (Croatia). This work uses uniparental and ancestry-informative markers (AIMs) to explore the effects of historic migratory and admixture patterns on the current genetic composition of Punta Arenas. METHODS: We analyzed mitochondrial DNA (mtDNA), Y-chromosome single-nucleotide polymorphisms (SNPs), and 141 AIMs obtained from 129 DNA samples from male residents with regional ancestry. After characterizing uniparental lineages and ancestry proportions, multivariate analysis was used to explore relationships among the various types of data. RESULTS: Punta Arenas has an admixed population with three main genetic components: European (56.5%), northern Native (11.3%), and south-central Native (28.6%). The Native component is preponderant in the mtDNA (83.76%), while the foreign component predominates in the Y-chromosome (92.25%). Non-Native mtDNA lineages are associated with European genetic ancestry, and Native mtDNA lineages originated mainly in the southern and southernmost regions of Chile. Most non-Native Y-chromosome SNPs originated in Spain, and secondly, in Croatia. CONCLUSIONS: The population of Punta Arenas is mainly of Chilote origin with south-central Native and Spanish ancestral components, as well as some Croatian components. The persistence of local Native lineages is notable, suggesting continuity with the ancestral populations of the region such as the Kawésqar, Aönikenk, Yámana, or Selknam peoples. This study contributes to our knowledge of local history and its links to national and global developments in genetic ancestry.

Native American mitochondrial lineages in admixed populations from Chile: Detecting recent migrations during post-Columbian times using geographically restricted lineages.

OBJECTIVES: To analyze the mitochondrial diversity in three admixed populations and evaluate the historical migration effect of native southern population movement to Santiago (capital of Chile). The intensity of migration was quantified using three mitochondrial lineages restricted to South-Central native groups. METHODS: D-loop sequences were genotyped in 550 unrelated individuals from San Felipe-Los Andes (n = 108), Santiago (n = 217), and Concepción (n = 225). Sequence processing, alignment, and haplogroup inference were carried out, and different genetic structure analyses were performed for haplogroup frequencies and D-loop sequences. RESULTS: The Native lineages B2i2, C1b13, and D1g were the most frequent haplogroups, especially in Santiago (71.8%). Despite the distance, this city showed a high-genetic affinity with southern populations, including Concepción (~500 km distant) and native groups, rather than with those from San Felipe-Los Andes (<100 km distant). In fact, there was a negative correlation between geographical and genetic distance among these cities (r corr = -0.5593, p value = 0.8387). Network analysis revealed shared haplotypes between Santiago, Concepción, and other southern populations. Finally, we found lineages from Concepción acting as ancestral nodes in the northern clade. CONCLUSIONS: Considering the geographic distances from these cities, the results were not consistent with a model of genetic isolation by geographic distance, revealing the effects of a historical migration process from the south to the capital. We also show evidence of possible north-to-south migration during admixture onset in Concepción and in addition, we were able to identify previously unreported mitochondrial diversity in urban populations that became lost in Native groups post-European contact.

Challenges and Lessons Learned After Hurricane Maria: Learning Points for the Medical Student Community.

On September 20 of 2017, Hurricane Maria made landfall in Puerto Rico as a strong category 4 hurricane with destructive winds and flooding. Everyone suffered in the aftermath of the hurricane due to overwhelming destruction and lack of available resources. For medical students, these conditions were intensified due to their duty as first responders, academic responsibilities from medical school, personal losses, and financial difficulties. Despite the hardships, these students learned lessons and found solutions to overcome their challenges. The objective of this article is to portray the situations that medical students confronted and offer suggestions on how medical students and academic institutions can prepare for future natural disasters.

Exploring Serum Transferrin Regulation of Nonferric Metal Therapeutic Function and Toxicity.

Serum transferrin (sTf) plays a pivotal role in regulating iron biodistribution and homeostasis within the body. The molecular details of sTf Fe(III) binding blood transport, and cellular delivery through transferrin receptor-mediated endocytosis are generally well-understood. Emerging interest exists in exploring sTf complexation of nonferric metals as it facilitates the therapeutic potential and toxicity of several of them. This review explores recent X-ray structural and physiologically relevant metal speciation studies to understand how sTf partakes in the bioactivity of key non-redox active hard Lewis acidic metals. It challenges preconceived notions of sTf structure function correlations that were based exclusively on the Fe(III) model by revealing distinct coordination modalities that nonferric metal ions can adopt and different modes of binding to metal-free and Fe(III)-bound sTf that can directly influence how they enter into cells and, ultimately, how they may impact human health. This knowledge informs on biomedical strategies to engineer sTf as a delivery vehicle for metal-based diagnostic and therapeutic agents in the cancer field. It is the intention of this work to open new avenues for characterizing the functionality and medical utility of nonferric-bound sTf and to expand the significance of this protein in the context of bioinorganic chemistry.

Evaluación de la transferencia de adolescentes desde una unidad de cardiología pediátrica a una de adultos / Transfering adolescents from pediatric to adult cardiology units: evaluation

Resumen: Objetivos: evaluar la transferencia de adolescentes desde Cardiología Pediátrica (CP) a Cardiología de Adultos (CA) en el Hospital Dr. Hernán Henríquez de Temuco (HHHT), determinando si recibieron su primera atención en CA en la fecha requerida y si los controles se ajustaron al plazo indicado. Evaluar si la complejidad de la cardiopatía y ruralidad se asocian al cumplimiento en ambos objetivos, en los pacientes sin seguimiento adecuado. Material y Método: revisión de fichas de pacientes atendidos en CP del HHHT que, cumplida la edad requerida, fueron transferidos a CA, entre Octubre 2014 - Julio de 2017. Resultados: De 53 pacientes transferidos de CPCA, 12 (22.6%) tuvo traspaso no efectivo; de ellos, 6 presentaban complejidad moderada-alta (66,6%) y 3 eran rurales (25%). De 28 pacientes ingresados a CA, 14 (50%) tenían seguimiento inefectivo; de ellos 13 (92.6%) tenían cardiopatías de moderada-alta complejidad y 3 (21.5%) provenían de áreas rurales. Conclusiones: la transferencia de CP - CA fue inefectiva en 22.6% de los pacientes; la complejidad de la cardiopatía no se asoció al resultado de la transferencia en este grupo. En CA el seguimiento fue inefectivo en la mitad de los pacientes; de ellos, 92.8% tenían cardiopatías de moderada-alta complejidad, lo que fue estadísticamente significativo respecto de la complejidad en todos los pacientes traspasados. El domicilio no estuvo asociado a la pérdida de pacientes en la transferencia ni en el seguimiento. Estos hallazgos nos permitieron tomar medidas de mejoría en la transferencia y los controles en CA que esperamos mejoren los resultados futuros.

Abstracts: Aim: To evaluate the transfer of adolescents from Pediatric Cardiology (PC) to Adult Cardiology (AC) at Hospital Dr. Hernán Henríquez de Temuco (HHHT). We determined whether they got their first care in AC on the required date and whether controls were performed on the period prescribed. Also, to evaluate whether the complexity of cardiac disease and the patient's place of residence influenced the accomplishment of the objectives, in patients without adequate following. Material and Method: Retrospective review of clinical records of patients that were treated in PC at HHHT who, having the required age were transferred to AC, between October 2014 and July 2017. Results: Of 53 patients that were transferred from PC to AC, 12 (22.6%) had an non effective transfer; 6 of them had moderate to high complexity cardiac lesions (66.6%) and 3 lived in rural areas (25%). Of 28 patients admitted to AC, 14 (50%) had a non effective follow up and 13 (92.8%) had moderate to high complexity forms of heart disease; 3 (21.5%) came from rural areas. Conclusions: Transfer of patients from PC to AC was not effective in 22.6% of patients. The complexity of the disease was not related to the results of transfer in this group. At AC the follow-up was not effective in half the patients; from these, 92.6% had moderate to high complexity heart disease, which was significantly different from the complexity of all patients transferred. The place of residence was not relates to transfer neither to follow-up. These findings allowed us to make improvement in the transfer processes and the follow up at AC.

Huella de carbono en el Hospital Base de Puerto Montt / Measurement of the carbon footprint at a regional hospital

Background: Measuring the carbon footprint (CF) makes it possible to estimate the contribution of clinical activity to global warming. Aim: To measure the emitter components of CO2 equivalents (CO2e) at the Hospital Base, Puerto Montt (HBPM). Material and methods: Descriptive study with data collected retrospectively between January and December 2016 from the HBPM database. The data analyzes direct and indirect emissions as well as other indirect emissions beyond the organizational limits. Results: Of the 9,660.3 tons of CO2e emitted by the HBPM in 2016, 46% were derived from consumption of electricity, 29% derived from the generation of residues, and 10% from clinical gas consumption, of which Sevoflurane was the greatest contributor. Conclusions: Clinical gases are a significant source of CO2e emissions. Sevoflurane alone is in fourth place in CO2e emissions at the HBPM. Estimating the CF produced by HBPM is the first step in the discussion of measures to reduce the environmental impact of our activity.
