Hidrocoria en semillas de Agave victoriae-reginae T. Moore, especie en peligro de extinción: Morfología y anatomía como facilitadores de la hidro-dispersión y germinación
Agave victoriae-reginae is an endemic species from Chihuahuan Desert which grows on canyon walls. It has flattened seeds that can be dispersed during episodic flood events. This study was focused on examining possible morphological and anatomical adaptations which promote seed hydro-dispersion. A morphological and anatomical seed analysis by scanning electron microscopy (SEM) was performed. Aspects of permeability, flotation, germination and germination rate (T50) for treatment and seed sizes were evaluated. The seeds are different in length, diameter, thickness, but not in weight; lacryform semi-flat shape and covered with porous air chambers in the hypodermis and were considered neutral photoblastic. We conclude that seeds of A. victoriae-reginae have hydro-dispersion characteristics.Agave victoriae-reginae es una especie endémica del Desierto Chihuahuense y crece sobre paredes en cañones. Posee semillas aplanadas que pueden ser dispersadas durante eventos episódicos de inundación. La presente investigación se basó en determinar posibles adaptaciones morfológicas y anatómicas en las semillas que favorecen la hidro-dispersión. Se realizó un análisis morfológico y anatómico de las semillas mediante microscopía electrónica de barrido (MEB). Se evaluaron aspectos de permeabilidad, fl otabilidad, germinación y velocidad de germinación (T50) por tratamientos y tamaños de semilla. Las semillas son diferentes en longitud, diámetro, espesor y no en peso; con forma lacriforme semiplanas y cubierta porosa con cámaras de aire en la hipodermis y son consideradas fotoblásticas neutras. Se concluye que las semillas de la especie poseen características propias para la hidro-dispersión
Transancestral mapping and genetic load in systemic lupus erythematosus
Systemic lupus erythematosus (SLE) is an autoimmune disease with marked gender and ethnic disparities. We report a large transancestral association study of SLE using Immunochip genotype data from 27,574 individuals of European (EA), African (AA) and Hispanic Amerindian (HA) ancestry. We identify 58 distinct non-HLA regions in EA, 9 in AA and 16 in HA (B50% of these regions have multiple independent associations); these include 24 novel SLE regions (Po5 10 8), refined association signals in established regions, extended associations to additional ancestries, and a disentangled complex HLA multigenic effect. The risk allele count (genetic load) exhibits an accelerating pattern of SLE risk, leading us to posit a cumulative hit hypothesis for autoimmune disease. Comparing results across the three ancestries identifies both ancestry-dependent and ancestry-independent contributions to SLE risk. Our results are consistent with the unique and complex histories of the populations sampled, and collectively help clarify the genetic architecture and ethnic disparities in SL
Evolving trends in the management of acute appendicitis during COVID-19 waves. The ACIE appy II study
Background: In 2020, ACIE Appy study showed that COVID-19 pandemic heavily affected the management of patients with acute appendicitis (AA) worldwide, with an increased rate of non-operative management (NOM) strategies and a trend toward open surgery due to concern of virus transmission by laparoscopy and controversial recommendations on this issue. The aim of this study was to survey again the same group of surgeons to assess if any difference in management attitudes of AA had occurred in the later stages of the outbreak.
Methods: From August 15 to September 30, 2021, an online questionnaire was sent to all 709 participants of the ACIE Appy study. The questionnaire included questions on personal protective equipment (PPE), local policies and screening for SARS-CoV-2 infection, NOM, surgical approach and disease presentations in 2021. The results were compared with the results from the previous study.
Results: A total of 476 answers were collected (response rate 67.1%). Screening policies were significatively improved with most patients screened regardless of symptoms (89.5% vs. 37.4%) with PCR and antigenic test as the preferred test (74.1% vs. 26.3%). More patients tested positive before surgery and commercial systems were the preferred ones to filter smoke plumes during laparoscopy. Laparoscopic appendicectomy was the first option in the treatment of AA, with a declined use of NOM.
Conclusion: Management of AA has improved in the last waves of pandemic. Increased evidence regarding SARS-COV-2 infection along with a timely healthcare systems response has been translated into tailored attitudes and a better care for patients with AA worldwide
Respuestas locales frente a la globalización económica. Productos regionales de la Costa Sur de Jalisco, México
El fenómeno de la globalización ha alcanzado incluso los sitios que solíamos creer muy rurales o demasiado alejados de las telecomunicaciones y sus intereses, sin embargo, especialmente en esas zonas rurales, la globalización se ha convertido en un fenómeno que trae consigo efectos negativos, como son la degradación ecológica y la destrucción de culturas que terminan afectando todos los aspectos de la vida de una comunidad.
Es por ello que en contraposición a esa amenaza que cada día se vuelve más difícil de enfrentar, surgen movimientos llamados alternativos que trabajan por dar respuesta y soluciones a esos problemas que la globalización trae consigo y cuyo fin es reforzar la identidad local, los valores comunitarios para alcanzar cierta autosuficiencia mediante formas justas y sustentables de comercialización y producción.
Este libro presenta el contexto del proceso de globalización en la Costa Sur del estado de Jalisco, principalmente proyectos de desarrollo alternativo y sustentable en la producción de los llamados productos regionales, enfocándose en 32 casos de estudio en las experiencias tanto locales como institucionales que se han vivido en éste ámbito junto con sus retos a superar y visión a futuro
Consensus-based management protocol (CREVICE protocol) for the treatment of severe traumatic brain injury based on imaging and clinical examination for use when intracranial pressure monitoring is not employed
Globally, intracranial pressure (ICP) monitoring use in severe traumatic brain injury (sTBI) is inconsistent and susceptible to resource limitations and clinical philosophies. For situations without monitoring, there is no published comprehensive management algorithm specific to identifying and treating suspected intracranial hypertension (SICH) outside of the one ad hoc Imaging and Clinical Examination (ICE) protocol in the Benchmark Evidence from South American Trials: Treatment of Intracranial Pressure (BEST:TRIP) trial. As part of an ongoing National Institutes of Health (NIH)-supported project, a consensus conference involving 43 experienced Latin American Intensivists and Neurosurgeons who routinely care for sTBI patients without ICP monitoring, refined, revised, and augmented the original BEST:TRIP algorithm. Based on BEST:TRIP trial data and pre-meeting polling, 11 issues were targeted for development. We used Delphi-based methodology to codify individual statements and the final algorithm, using a group agreement threshold of 80%. The resulting CREVICE (Consensus REVised ICE) algorithm defines SICH and addresses both general management and specific treatment. SICH treatment modalities are organized into tiers to guide treatment escalation and tapering. Treatment schedules were developed to facilitate targeted management of disease severity. A decision-support model, based on the group's combined practices, is provided to guide this process. This algorithm provides the first comprehensive management algorithm for treating sTBI patients when ICP monitoring is not available. It is intended to provide a framework to guide clinical care and direct future research toward sTBI management. Because of the dearth of relevant literature, it is explicitly consensus based, and is provided solely as a resource (a “consensus-based curbside consult”) to assist in treating sTBI in general intensive care units in resource-limited environments
