The mosquitoes (Diptera: Culicidae) of the Mexican Yucatan Peninsula: a comprehensive review on the use of taxonomic names.

The Yucatan Peninsula is a biogeographic province of the Neotropical region which is mostly encompassed by the 3 Mexican states of Campeche, Quintana Roo, and Yucatán. During the development of the International Joint Laboratory ELDORADO (Ecosystem, bioLogical Diversity, habitat mOdifications and Risk of emerging PAthogens and Diseases in MexicO), a French-Mexican collaboration between the IRD (Institut de Recherche pour le Développement) and UNAM (Universidad Nacional Autónoma de México) in Mérida, it became evident that many putative mosquito species names recorded in the Mexican Yucatan Peninsula were misidentifications/misinterpretations or from the uncritical repetition of incorrect literature records. To provide a stronger foundation for future studies, the mosquito fauna of the Mexican Yucatan Peninsula is here comprehensively reviewed using current knowledge of taxonomy, ecology, and distribution of species through extensive bibliographic research, and examination of newly collected specimens. As a result, 90 mosquito species classified among 16 genera and 24 subgenera are recognized to occur in the Mexican Yucatan Peninsula, including 1 new peninsula record and 3 new state records.

Differences in family functioning before and during the COVID-19 pandemic: an observational study in Peruvian families.

The COVID-19 pandemic has had a major impact on family relationships, as several families have lost family members due to COVID-19 pandemic and become physically and emotionally estranged due to lockdown measures and critically economic periods. Our study contrasted two hypotheses: (1) family functioning changed notably before and after the COVID-19 pandemic initiation in terms of cohesion, flexibility, communication and satisfaction; (2) balanced families have a greater capacity to strictly comply with quarantine (i.e., social confinement), compared to unbalanced families. We performed an observational study comparing family functioning between two independent groups, evaluated before and during the first wave of the COVID-19 pandemic in Peru. A total of 7,980 participants were included in the study. For the first hypothesis, we found that, during the pandemic, families became more balanced in terms of cohesion (adjusted before-during mean difference or ß1 = 1.4; 95% CI [1.0-1.7]) and flexibility (ß2 = 2.0; 95% CI [1.6-2.4]), and families were less disengaged (ß3 = -1.9; 95% CI [-2.3 to -1.5]) and chaotic (ß4 = -2.9; 95% CI [-3.3 to -2.4]). Regarding the second hypothesis, we confirmed that families with balanced cohesion (adjusted prevalence ratio or aPR = 1.16; 95% CI [1.12-1.19) and flexibility (aPR = 1.23; 95% CI [1.18-1.27]) allowed greater compliance with quarantine restrictions; while disengaged (aPR = 0.91; 95% CI [0.88-0.93]) and chaotic families (aPR = 0.89; 95% CI [0.87-0.92]) were more likely to partially comply or not comply with the quarantine. Finally, family communication (aPR = 1.17; 95% CI [1.11-1.24]) and satisfaction (aPR = 1.18; 95% CI [1.11-1.25]) also played a role in favouring quarantine compliance. This new evidence enlightens the family systems theory while informing future interventions for improving compliance with quarantine measures in the context of social confinement.

Label-free fluorescence microscopy: revisiting the opportunities with autofluorescent molecules and harmonic generations as biosensors and biomarkers for quantitative biology.

Over the past decade, the utilization of advanced fluorescence microscopy technologies has presented numerous opportunities to study or re-investigate autofluorescent molecules and harmonic generation signals as molecular biomarkers and biosensors for in vivo cell and tissue studies. The label-free approaches benefit from the endogenous fluorescent molecules within the cell and take advantage of their spectroscopy properties to address biological questions. Harmonic generation can be used as a tool to identify the occurrence of fibrillar or lipid deposits in tissues, by using second and third-harmonic generation microscopy. Combining autofluorescence with novel techniques and tools such as fluorescence lifetime imaging microscopy (FLIM) and hyperspectral imaging (HSI) with model-free analysis of phasor plots has revolutionized the understanding of molecular processes such as cellular metabolism. These tools provide quantitative information that is often hidden under classical intensity-based microscopy. In this short review, we aim to illustrate how some of these technologies and techniques may enable investigation without the need to add a foreign fluorescence molecule that can modify or affect the results. We address some of the most important autofluorescence molecules and their spectroscopic properties to illustrate the potential of these combined tools. We discuss using them as biomarkers and biosensors and, under the lens of this new technology, identify some of the challenges and potentials for future advances in the field.

Novel opportunities from bioimaging to understand the trafficking and maturation of intracellular pulmonary surfactant and its role in lung diseases.

Pulmonary surfactant (PS), a complex mixture of lipids and proteins, is essential for maintaining proper lung function. It reduces surface tension in the alveoli, preventing collapse during expiration and facilitating re-expansion during inspiration. Additionally, PS has crucial roles in the respiratory system's innate defense and immune regulation. Dysfunction of PS contributes to various respiratory diseases, including neonatal respiratory distress syndrome (NRDS), adult respiratory distress syndrome (ARDS), COVID-19-associated ARDS, and ventilator-induced lung injury (VILI), among others. Furthermore, PS alterations play a significant role in chronic lung diseases such as chronic obstructive pulmonary disease (COPD) and idiopathic pulmonary fibrosis (IPF). The intracellular stage involves storing and releasing a specialized subcellular organelle known as lamellar bodies (LB). The maturation of these organelles requires coordinated signaling to organize their intracellular organization in time and space. LB's intracellular maturation involves the lipid composition and critical processing of surfactant proteins to achieve proper functionality. Over a decade ago, the supramolecular organization of lamellar bodies was studied using electron microscopy. In recent years, novel bioimaging tools combining spectroscopy and microscopy have been utilized to investigate the in cellulo intracellular organization of lamellar bodies temporally and spatially. This short review provides an up-to-date understanding of intracellular LBs. Hyperspectral imaging and phasor analysis have allowed identifying specific transitions in LB's hydration, providing insights into their membrane dynamics and structure. A discussion and overview of the latest approaches that have contributed to a new comprehension of the trafficking and structure of lamellar bodies is presented.

Predictors of severity in severe respiratory infection in children with COVID-19 respiratory infection in a developing country.

On March 11, 2020, the WHO declared the COVID-19 pandemic. This name was given to the disease caused by the SARS-CoV 2 virus at its outbreak in December 2019 in Wuhan, Hubei, China. In Colombia, a significant number of cases have been confirmed. The aim of this study was to evaluate children with respiratory symptoms caused by SARS-CoV2 infection, identifying independent predictors of risk of having a severe illness, thus leading to an early approach and intervention in our patients, especially in children with comorbidities. An analytical cross-sectional study was conducted between April 1, 2020 and March 31, 2021 at a fourth-level referral institution in Bogotá on patients under 18 years of age with respiratory symptoms and a COVID-19 diagnosis confirmed in the laboratory. An explanatory binary logistic regression model was performed with an outcome variable of admission to the intensive care unit. A total of 385 children were included in the study, with ages between 9 months and 17 years of age; 50.1% were male, and the ICR was 9.75 years. 41.6% had some comorbidity, 13.5% were admitted to the pediatric ICU, and 3.6% of the total number of patients died. The predictor variables were: use of antibiotics in the first 24 h, neurological comorbidity, and consolidation shown in the chest X-ray. This explains 38.7% of the variability of the variable. In this cohort of patients with COVID-19-associated respiratory symptoms, we identified predictors of severity, so we consider that these patients require a risk approach that allows timely and adequate care.

Riñón único funcionante y su seguimiento en Pediatría

Contexto: el riñón único funcionante (RUF) es una entidad que puede ser de tipo congénito y es causada por una agenesia renal unilateral o un riñón displásico multiquístico, o adquirido de forma secundaria a una nefrectomía unilateral, condicionando al paciente a un seguimiento estricto rutinario, así como en la implementación de algunas pautas de prevención en los pacientes pediátricos. Objetivo: analizar la importancia del seguimiento en los pacientes pediátricos con RUF. Metodologí:a se hace una revisión de la literatura mostrando desde la embriología, fisiología, etiología, aspectos clínicos y estudios diagnósticos en pacientes con RUF para así, posteriormente, ofrecer unas pautas de seguimiento y manejo en pacientes pediátricos. Resultados: los pacientes con RUF pueden presentar hiperfiltración glomerular compensatoria, seguida de lesión glomerular con hipertensión, albuminuria y reducción de la tasa de filtración glomerular, sin embargo, para prevenir el daño renal se deben realizar seguimientos clínico, paraclínico e imagenológico cuidadosos de todo paciente con RUF, según la condición lo amerite. Conclusiones: se hace necesaria la unificación de pautas de seguimiento en los pacientes pediátricos con RUF y hacer énfasis en aquellos factores de riesgo que predisponen a compromiso renal.

Background: The Solitary functioning kidney (SFK) is an entity that can be congenital type caused by unilateral renal agenesis or multicystic dysplastic kidney, or acquired secondary to unilateral nephrectomy conditioning to a strict routine follow-up, as well as the implementation of some prevention guidelines in pediatric patients. Purpose: To analyze the importance of follow-up in pediatric patients with a single functioning kidney. Methodology: A review of the literature is made showing embryology, physiology, etiology, clinical aspects and diagnostic studies in patients with SFK in order to subsequently offer guidelines for follow-up and management in pediatric patients. Results: Patients with SFK may present compensatory glomerular hyperfiltration, followed by glomerular injury with hypertension, albuminuria and reduced glomerular filtration rate, however, to prevent renal damage a careful clinical, paraclinical and imaging follow-up of every patient with SFK should be performed as the condition warrants. Conclusions: It is necessary to unify follow-up guidelines in pediatric patients with SFK and to emphasize those risk factors that predispose to renal compromise.

Síndrome de opsoclonia mioclonia idiopático: Reporte de caso en una paciente de 13 meses / Idiopathic opsoclonus myoclonus syndrome: Case report in a 13-month-old female patient

Resumen El síndrome de opsoclonia mioclonía es una entidad neurológica poco frecuente que afecta a los niños en la etapa preescolar. Clínicamente se caracteriza por una triada clásica de opsoclonía, mioclonía y ataxia aguda, con una evolución progresiva o incluso de manera incompleta. Su etiología puede ser paraneoplásica, en la mayoría de los casos en asociación con neuroblastomas, así como postinfecciosa o parainfecciosa, autoinmune o idiopática. En objetivo del tratamiento es la inmunomodulación con terapia de primera línea con esteroides endovenosos aunque pudiendo asociarse a recaídas y secuelas a largo plazo en el ámbito neurológico y conductual. El síndrome de opsoclonia mioclonía representa un reto diagnóstico en los pacientes con ataxia aguda dada la variedad de presentación clínica, por tanto es importante tener una alta sospecha diagnostica para garantizar un tratamiento oportuno y evitar secuelas futuras.

Abstract Opsoclonus myoclonus syndrome is a rare neurological entity affecting preschool children. Clinically it is characterized by a classic triad of opsoclonus, myoclonus, and acute ataxia, with a progressive or even incomplete course. Its etiology can be paraneoplastic, in most cases in association with neuroblastomas, as well as postinfectious or parainfectious, autoimmune or idiopathic. The goal of treatment is immunomodulation with first-line therapy with intravenous steroids, although it can be associated with relapses and long-term neurological and behavioral sequelae. The opsoclonus myoclonus syndrome represents a diagnostic challenge in patients with acute ataxia given the variety of clinical presentations, therefore it is important to have a high diagnostic suspicion to ensure timely treatment and aoid future sequelae.

Actualización de resultados demográficos y terapéuticos de pacientes con Leucemia Mieloide Aguda no promielocítica en el Hospital Clínico de la Pontificia Universidad Católica de Chile / Acute myeloid leukemia. Analysis of 114 patients

BACKGROUND: Acute myeloid leukemia (AML) is the most common leukemia in adults. Aim: To Describe our population of patients with AML and report the outcomes of our treatments. MATERIAL AND METHODS: Review of electronic clinical records of 114 patients with AML with a median age of 57 years (59% men). Results: Seventeen percent of patients were classified as low risk, 38% as intermediate risk and 33% as high risk. Seventy-six percent of patients were treated with intensive chemotherapy. Five years overall survival according to cytogenetic risk was 59, 41, and 12% in low, intermediate, and high-risk patients, respectively. The outcomes were better in patients under 60 years. The median survival of patients treated with intensive chemotherapy aged less than 60 years and 60 years and above was 3.4 and 1 year, respectively. CONCLUSIONS: Our results are comparable to those reported in developed countries. Improving the survival of patients 60 years and older is our main challenge.

[Age does not affect the outcome of allogeneic hematopoietic precursor transplantation for acute myeloid leukemia]. / Resultados a largo plazo de una cohorte chilena: la edad del paciente no incide en el resultado del trasplante alogénico de precursores hematopoyéticos para leucemia mieloide aguda.

BACKGROUND: In our country, transplantation centers differ in the age limit for allogeneic hematopoietic transplantation (ALOHT). In our program, transplants with age- adjusted conditioning are performed in patients until 70 years old. Currently more than 60% of ALOHT reported to the Center for International Bone Marrow Transplantation Research (CIBMTR) are performed in patients older than 40 years. AIM: To report our experience with ALOHT in acute myelogenous leukemia (AML), analyzing patient age at transplantation in different periods and transplant results in different age groups. MATERIAL AND METHODS: A retrospective analysis of the database of adult hematopoietic transplants in AML patients was performed. Demographic data, disease characteristics, transplant data, survival and relapse times, and mortality were collected. RESULTS: In our program, 1030 transplants were performed in adults and 119 ALOHT were performed in AML patients, between 1990 and 2020. The median age of patients in all periods was 41 years, (range 16-69). The median age was 33 and 45 years, in the periods 1990-2000 and 2000-2020 respectively (p < 0.01). Seventy-eight patients received myeloablative conditioning (median age 44 years) and 41 reduced intensity conditioning (median age 53 years). Five-year overall survival was 44.6% (confidence intervals (CI) 41-48). Non relapse mortality of all periods was 19% (CI 17 - 40%) and relapse rate was 17 % (CI 16-22). No difference in five years overall survival among patients younger than 40, 41 to 50 and over 51 years was observed. CONCLUSIONS: Overall Survival, non-relapse mortality and relapse rate were similar in younger and older patients in our program and similar to those previously reported in other centers.

El derecho a la alimentación y la justicia de género en Venezuela. Indicadores de Progreso / The Right to Food and Gender Justice in Venezuela. Progress Indicators

Se establecieron Indicadores estructurales, de procesos y de resultados, como indicadores de procesos basados en los establecidos en el Protocolo de San Salvador, para el monitoreo del derecho a la alimentación en Venezuela bajo el principio transversal de igualdad y no discriminación: la justicia de género. Al determinar Indicadores estructurales, se estableció que en Venezuela no se contempla el derecho a la alimentación adecuada, bajo una declaración expresa en la Constitución de la República Bolivariana de Venezuela y/o las Leyes establecidas para tal fin, debiendo establecerse su declaración expresa bajo el orden jurídico legal del país, así como su vinculación con poblaciones en situación de vulnerabilidad, atendiendo lo concerniente al derecho a la alimentación y la población con justicia de género. Los Indicadores de procesos establecidos determinaron una elevada opacidad estadística en instituciones oficiales y gubernamentales sobre los alcances del establecimiento de las denominadas misiones sociales y programas de ayuda alimentaria, así como el alcance desglosado de los programas por grupos tradicionalmente excluidos como el enfoque de justicia de género. Al determinar indicadores de resultados, no se evidenciaron en los portales oficiales de los entes del Estado, la existencia de estadísticas de tasa de desnutrición de forma general o para distintos sectores poblacionales (niños, niñas, jóvenes, mujeres, adultos mayores, personas con discapacidad, grupos étnicos) sobre la base de la Tasa de desnutrición global. La aplicación de estos indicadores determinaron el no cumplimiento por parte del estado, de la garantía de un derecho a la alimentación adecuada, requiriéndose una profunda transformación estructural y de procesos, bajo la premisa de los derechos humanos, a los fines de poder establecer una significativa y necesaria mejora en los indicadores de resultados, así como generar soluciones para transformar las desigualdades de género, ante la creciente tendencia del establecimiento de una feminización de la pobreza en Venezuela(AU)

Structural, process and result indicators were established, as process indicators based on those established in the Protocol of San Salvador, for monitoring the right to food in Venezuela, under the cross-cutting principle of equality and non-discrimination: gender justice . When determining structural indicators, it was established that in Venezuela the right to adequate food is not contemplated, under an express declaration in the Constitution of the Bolivarian Republic of Venezuela and / or the Laws established for that purpose, and its express declaration must be established under the legal order of the country, as well as its relationship with populations in vulnerable situations, taking into account the right to food and the population with gender justice. The indicators of established processes determined, a high statistical opacity in official and governmental institutions regarding the scope of the establishment of the so-called social missions and food aid programs, as well as the disaggregated scope of the programs by traditionally excluded groups, such as the gender justice approach. When determining results indicators, the existence of statistics on the malnutrition rate in general or for different population sectors (boys, girls, youth, women, older adults, people with disabilities, ethnic groups) based on the Global Malnutrition Rate, was not evidenced in the official portals of the State entities. The application of these indicators determined the non-compliance by the state with the guarantee of a right to adequate food, requiring a profound structural and process transformation, under the premise of human rights, in order to establish a significant and necessary improvement in the results indicators, as well as generating solutions to transform gender inequalities, given the growing trend of the establishment of a feminization of poverty in Venezuela(AU)

Insights into the Host Specificity of Mosquito-Borne Flaviviruses Infecting Wild Mammals.

Mosquito-borne flaviviruses (MBFVs) are of public and animal health concern because they cause millions of human deaths annually and impact domestic animals and wildlife globally. MBFVs are phylogenetically divided into two clades, one is transmitted by Aedes mosquitoes (Ae-MBFVs) associated with mammals and the other by Culex mosquitoes (Cx-MBFVs) associated with birds. However, this assumption has not been evaluated. Here, we synthesized 79 published reports of MBFVs from wild mammals, estimating their host. Then, we tested whether the host specificity was biased to sampling and investigation efforts or to phylogenetic relationships using a viral phylogenetic tree drawn from analyzing whole flavivirus genomes obtained in GenBank. We found in total 18 flaviviruses, nine related to Aedes spp. and nine to Culex spp. infecting 129 mammal species. Thus, this supports that vectors are transmitting MBFV across available host clades and that ornithophilic mosquitoes are readily infecting mammals. Although most of the mosquito species are generalists in their host-feeding preferences, we also found a certain degree of MBFV's specificity, as most of them infect closely related mammal species. The present study integrates knowledge regarding MBFVs, and it may help to understand their transmission dynamics between viruses, vectors, and mammal hosts.

El derecho a la alimentación y la feminización de la pobreza en Venezuela / The right to food and feminization of poverty in Venezuela

El Estado no ha utilizado todos los recursos disponibles para garantizar la realización progresiva del derecho a la alimentación. Este incumplimiento sistemático, profundiza la vulnerabilidad del derecho a la alimentación de la nación, agrava la inseguridad alimentaria y la crisis social y económica del país, lo que deriva en la incidencia directa en las mujeres, de situaciones que fomentan la feminización de la pobreza. Este artículo presenta una revisión del subconsumo calórico crónico e inadecuado en mujeres, con énfasis en mujeres embarazadas, el fomento de la existencia de matricentralidad, el aumento en la proporción de hogares con jefaturas de hogar ejercida por mujeres, la desigualdad de ingresos por género, la afectación de la salud reproductiva y aumento sustancial del embarazo precoz y muerte materna, el aumento en la proporción de mujeres económicamente inactivas, el aumento de brecha generacional en la dedicación en exclusividad de los quehaceres del hogar, y la segregación y discriminación laboral. Se evidenció en el país, una tendencia general de mujeres sobrecargadas de trabajo, con una tendencia al aumento de jefaturas del hogar ejercida por mujeres y una tendencia creciente a una feminización de la pobreza. Las observaciones indican que existen más posibilidades de que los hogares encabezados por mujeres sean más pobres y que la feminización de la pobreza acarrea la feminización de las estrategias de supervivencia y la posible continuidad generacional de la pobreza(AU)

The government has not used all available resources to guarantee the progressive realization of the right to food. This systematic breach deepens the vulnerability of the nation's right to food, aggravates food insecurity and the country's social and economic crisis, resulting in the direct impact on women of situations that foster the feminization of poverty. This article presents a review of chronic and inadequate caloric under-consumption in women, with emphasis on pregnant women, the promotion of the existence of matricentrality, the increase in the proportion of households headed by women, and income inequality by gender, the affectation of reproductive health and substantial increase in early pregnancy and maternal death, the increase in the proportion of economically inactive women, the increase in the generation gap in the exclusive dedication of household chores, and segregation and discrimination labor. In the country, there was a general tendency of women overloaded with work, with a tendency to increase the number of heads of households exercised by women and a growing tendency towards the constitution of a feminization of poverty. The observations indicate that there are more possibilities for women-headed households to be poorer and that the feminization of poverty leads to the feminization of survival strategies and the possible generational continuity of poverty(AU)

Outcomes in relapsed Hodgkin's lymphoma treated with autologous and allogeneic hematopoietic cell transplantation at the Pontificia Universidad Católica de Chile.

INTRODUCTION: Hodgkin's lymphoma is a highly curable disease. Autologous and reduced intensity allogeneic hematopoietic cell transplantations are alternatives to treat relapsed patients. Here, we report on the results of one service using these procedures. METHODS: All patients who underwent transplantations in our institution between 1996 and 2014 were retrospectively studied and demographics, toxicities and survival rate were analyzed. RESULTS: This study evaluated 24 autologous and five reduced intensity allogeneic transplantations: the median ages of the patients were 29 and 32 years, respectively. At the time of autologous transplantation, ten patients were in complete remission, nine had chemosensitive disease but were not in complete remission, three had refractory disease and the status of two is unknown. In the allogeneic group, two were in complete remission and three had chemosensitive disease. The 5-year overall survival after autologous transplantation was 42% (66% patients were in complete remission, 37% had chemosensitive disease with incomplete remission and 0% had refractory disease) and 1-year overall survival after allogeneic transplantation was 80%. Transplant-related mortality was 0% in patients conditioned with the ifosfamide/carboplatin/etoposide (ICE), carmustine/etoposide/cyclophosphamide (BEC) and carmustine/etoposide/cytarabine/melphalan (BEAM) regimens, 37% in patients conditioned with busulfan-based regimens and 20% in allogeneic transplantations. CONCLUSIONS: Hematopoietic cell transplantation for relapsed Hodgkin's lymphoma is a potentially curative procedure especially in patients in complete remission at the time of autologous transplantations, and possibly after allogeneic transplantations. Further studies are necessary to clarify the role of allogeneic transplantations in the treatment of relapsed Hodgkin's lymphoma.

Further studies are necessary to clarify the role of allogeneic transplantations in the treatment of relapsed Hodgkin's lymphoma.

Admission of hematopoietic cell transplantation patients to the intensive care unit at the Pontificia Universidad Católica de Chile Hospital.

Patients undergoing hematopoietic cell transplantation (HCT) can have complications that require management in the intensive care unit (ICU). We conducted a retrospective study of patients undergoing HCT between 2007 and 2011 with admission to the ICU. We analyzed 97 patients, with an average age of 37 (range, 15 to 68). The main indications for HCT were hematologic malignancies (84%, n = 82). Ninety percent (n = 87) received myeloablative conditioning. Thirty-one percent were admitted (autologous transplant recipients 15%, allogeneic transplant recipients 34%, and umbilical cord blood [UCB] transplant recipients 48%) with an average length of stay of 19 days (range, 1 to 73 days). The average time between transplantation and transfer was 15 days. The main causes of admission were acute respiratory failure (63%) and septic shock (20%). ICU mortality was 20% for autologous transplantations and 64% for allogeneic transplantations (adult donor and UCB combined). On average, patients died 108 days after the transplantation (range, 4 to 320 days). One-year overall survival, comparing patients entering the ICU with those never admitted, was 16% versus 82% (P < .0001) for allogeneic transplantations (adult donor and UCB combined) and 80% versus 89% (P = not significant) for autologous transplantations. Acute graft-versus-host disease was significantly associated with death in ICU after UCB HCT. ICU support is satisfactory in about one half of patients admitted, characterized by a short and medium term prognosis not as unfavorable as has been previously reported.
