Discovery and Designation of Type Specimens of Chrysomelidae (Coleoptera) From Argentina Described by E. von Harold in 1875
Type specimens of 14 species of Chrysomelidae from Cordova,
Argentina. collected by W. M. Davis and described by E. von
Harold in 1875, were discovered in the collections of the Museum
of Comparative Zoology (Harvard University). A few specimens
from some other museums such as the Museum fĂŒr Naturkunde der
Humboldt-UniversitÀt (Berlin), The Natural History Museum (London),
Institut Royal des Sciences Naturelles de Belgique (Brussels),
Museo Nacional de Hungaria (Budapest) are also apparently from
the original series. Lectotypes and paralectotypes are designated for
all species
Pediatric trauma and emergency surgery: an international cross-sectional survey among WSES members
Background: In contrast to adults, the situation for pediatric trauma care from an international point of view and the global management of severely injured children remain rather unclear. The current study investigates structural management of pediatric trauma in centers of different trauma levels as well as experiences with pediatric trauma management around the world. Methods: A web-survey had been distributed to the global mailing list of the World Society of Emergency Surgery from 10/2021-03/2022, investigating characteristics of respondents and affiliated hospitals, case-load of pediatric trauma patients, capacities and infrastructure for critical care in children, trauma team composition, clinical work-up and individual experiences with pediatric trauma management in response to patientsÂŽ age. The collaboration group was subdivided regarding sizes of affiliated hospitals to allow comparisons concerning hospital volumes. Comparable results were conducted to statistical analysis. Results: A total of 133 participants from 34 countries, i.e. 5 continents responded to the survey. They were most commonly affiliated with larger hospitals (>â500 beds in 72.9%) and with level I or II trauma centers (82.0%), respectively. 74.4% of hospitals offer unrestricted pediatric medical care, but only 63.2% and 42.9% of the participants had sufficient experiences with trauma care in childrenââ€â10 andââ€â5 years of age (pâ=â0.0014). This situation is aggravated in participants from smaller hospitals (pâ<â0.01). With regard to hospital size (â€â500 versusâ>â500 in-hospital beds), larger hospitals were more likely affiliated with advanced trauma centers, more elaborated pediatric intensive care infrastructure (pâ<â0.0001), treated children at all ages more frequently (pâ=â0.0938) and have higher case-loads of severely injured childrenâ<â12 years of age (pâ=â0.0009). Therefore, the majority of larger hospitals reserve either pediatric surgery departments or board-certified pediatric surgeons (pâ<â0.0001) and in-hospital trauma management is conducted more multi-disciplinarily. However, the majority of respondents does not feel prepared for treatment of severe pediatric trauma and call for special educational and practical training courses (overall: 80.2% and 64.3%, respectively). Conclusions: Multi-professional management of pediatric trauma and individual experiences with severely injured children depend on volumes, level of trauma centers and infrastructure of the hospital. However, respondents from hospitals at all levels of trauma care complain about an alarming lack of knowledge on pediatric trauma management
Diversity and ethics in trauma and acute care surgery teams: results from an international survey
Background Investigating the context of trauma and acute care surgery, the article aims at understanding the factors that can enhance some ethical aspects, namely the importance of patient consent, the perceptiveness of the ethical role of the trauma leader, and the perceived importance of ethics as an educational subject. Methods The article employs an international questionnaire promoted by the World Society of Emergency Surgery. Results Through the analysis of 402 fully filled questionnaires by surgeons from 72 different countries, the three main ethical topics are investigated through the lens of gender, membership of an academic or non-academic institution, an official trauma team, and a diverse group. In general terms, results highlight greater attention paid by surgeons belonging to academic institutions, official trauma teams, and diverse groups. Conclusions Our results underline that some organizational factors (e.g., the fact that the team belongs to a university context or is more diverse) might lead to the development of a higher sensibility on ethical matters. Embracing cultural diversity forces trauma teams to deal with different mindsets. Organizations should, therefore, consider those elements in defining their organizational procedures. Level of evidence Trauma and acute care teams work under tremendous pressure and complex circumstances, with their members needing to make ethical decisions quickly. The international survey allowed to shed light on how team assembly decisions might represent an opportunity to coordinate team member actions and increase performance
Correction to: Two years later: Is the SARS-CoV-2 pandemic still having an impact on emergency surgery? An international cross-sectional survey among WSES members
Background: The SARS-CoV-2 pandemic is still ongoing and a major challenge for health care services worldwide. In the first WSES COVID-19 emergency surgery survey, a strong negative impact on emergency surgery (ES) had been described already early in the pandemic situation. However, the knowledge is limited about current effects of the pandemic on patient flow through emergency rooms, daily routine and decision making in ES as well as their changes over time during the last two pandemic years. This second WSES COVID-19 emergency surgery survey investigates the impact of the SARS-CoV-2 pandemic on ES during the course of the pandemic.
Methods: A web survey had been distributed to medical specialists in ES during a four-week period from January 2022, investigating the impact of the pandemic on patients and septic diseases both requiring ES, structural problems due to the pandemic and time-to-intervention in ES routine.
Results: 367 collaborators from 59 countries responded to the survey. The majority indicated that the pandemic still significantly impacts on treatment and outcome of surgical emergency patients (83.1% and 78.5%, respectively). As reasons, the collaborators reported decreased case load in ES (44.7%), but patients presenting with more prolonged and severe diseases, especially concerning perforated appendicitis (62.1%) and diverticulitis (57.5%). Otherwise, approximately 50% of the participants still observe a delay in time-to-intervention in ES compared with the situation before the pandemic. Relevant causes leading to enlarged time-to-intervention in ES during the pandemic are persistent problems with in-hospital logistics, lacks in medical staff as well as operating room and intensive care capacities during the pandemic. This leads not only to the need for triage or transferring of ES patients to other hospitals, reported by 64.0% and 48.8% of the collaborators, respectively, but also to paradigm shifts in treatment modalities to non-operative approaches reported by 67.3% of the participants, especially in uncomplicated appendicitis, cholecystitis and multiple-recurrent diverticulitis.
Conclusions: The SARS-CoV-2 pandemic still significantly impacts on care and outcome of patients in ES. Well-known problems with in-hospital logistics are not sufficiently resolved by now; however, medical staff shortages and reduced capacities have been dramatically aggravated over last two pandemic years
Systqmatics and evolution of weevils of t,he genus Bagous Germar (Coleoptera: Curculionidae), III. Phylogenetic analysis of the species known from Japan
Phylogenetic analysis of members of Bagous known to occur in Japan was performed to produce an hypothesis about the phylogenetic relationships of the 17 species. Both manual and computer-aided reconstructions were performed. On the basis of this analysis, eight species groups were recognized, the B. pygmaeus group (including B. minor and B. pygmaeodes), the B. bipunctatus group (including B. kagiashi, B. ryukyuensis, B. occultus, B. spiculatus, B. bipunctatus and B. subcordatus), the B. fractus group (including B. fructus), the B. frit group (including B. fritodes), the B. transversus group (including B. youngi), the B. rotundatus group (including B. rotundatus), the B. buckinghami group (including B. buckinghami), and the B. proprius group (including B. proprius). The hypothesis of phylogeny compared well with a previous analysis of Australian species of the genus and integrated well with it. Combining Australian and Japanese species in the analysis did not significantly alter topology of branches. Thus, relationships of species and groups of species as determined independently for species of each of these geographically separated faunas is corroborated. This concordance indicates that phylogenetic analysis based on a subset of members of a taxon, while excluding the majority of its members, can be a valuable tool in development of a classification. Several species are known only from females and therefore cannot be confidently assigned to species groups: B. lewisi, B. subvirtarus, and B. tuberculosus. On the basis âof characters used for analysis, placement in relation to known species is equivocal because these species share homoplastic characters with several other species which are not closely related to each other. These species are placed in an uncertain position among Japanese Bagous. Also known only from females, B. subcordatus has genitalia rather similar to certain species in the B. bipunctatus group, and is tentatively assigned to that group as most closely related to B. bipunctatus. Species known only from male specimens (B. occultus and B. rotundatus) can be confidently placed phylogenetically because many of the important, phylogenetically useful characters are found in male genitalia. The Japanese Bagous constitute a diverse assemblage of species whose closest relatives occur in Southeast Asia, North America, or in the Palearctic Region. Several species groups represented in Japan are monobasic, but we fully expect that each is closely related to other, non-Japanese species with which we are unfamiliar at this time. Computer analysis using PAUP agrees closely with manual reconstruction of relationships; differences are due to the more conservative, compromising hypothesis presented. Manual reconstructions tend to be most similar to 50% majority-rule consensus trees
