    Background: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≄ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≀ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. Conclusions: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception

    CatĂĄlogo TaxonĂŽmico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil

    The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the CatĂĄlogo TaxonĂŽmico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others

Abdominal sternite VII, in ventral view, subrectangular, approximately 1.5 times wider than long; lateral margins parallel; ventral surface without setae; posterior margin with prominent broad subquadrate median lobe, slightly longer than lateral lobes (Fig. 19). Sternite VIII with two sclerotized regions (Fig. 20). Pygofer, in lateral view, well produced posteriorly; lobe surface with few setae on ventral and posterior margins; posterior margin rounded (Fig. 21). First valvifer, in lateral view, with anterior margin obliquely rectilinear; posterior margins almost acute (Fig. 22). First valvula, in lateral view, with dorsal sculptured area present on apical three-fifths, formed mostly by scale-like processes arranged in oblique lines; ventral sculptured area restricted to apical portion, formed mostly by scale-like processes; preapical region with ventral margin with small denticles; apex acute (Figs 22‒23). Second valvifer, in lateral view, higher than wide; group of setae present on median portion near posterior margin (Fig. 25). Second valvula, in lateral view, regularly broadened beyond basal curvature; dorsal margin with about 45 separated teeth, each approximately subquadrate, becoming gradually smaller, angulate, and more closed spaced towards apex; preapical region with ventral margin with distinct protuberance; apices narrowly rounded (Figs 25‒26). Third valvula, in lateral view, with basal half narrow and apical half distinctly expanded; apex rounded (Fig. 24).</p> <p> <b>Notes.</b> The description and photographs provided herein for the female of <i>P. triquetra</i> are based on the association of males and females from Santo Antonio do Tauá, Pará State, Brazil. This is the only locality represented among studied material where both males and females of Amazonian <i>Propetes</i> were collected. This particular female of <i>P. triquetra</i> (as well as, other females listed in the examined material below from Eastern Amazonia) agree with the external morphology of the holotype of <i>P. compressa</i> and lectotype of <i>P. trimaculata</i>, including the shape of the abdominal sternite VII. Dissections of the genitalia of these female specimens did not reveal any diagnostic difference to separate them in different species and, for this reason, the female genitalia of these primary types were spared from dissection. So it is most probable that no morphological differences are found in females of <i>P. triquetra</i> and <i>P. sabakibara</i> and some female specimens treated herein as <i>P. triquetra</i> could in fact be <i>P. sakakibara</i>. Nevertheless, until more Amazonian <i>Propetes</i> females are available for study and show reliable diagnostic characters to differentiate these two species, we prefer to consider all available females from Eastern Amazonia (Pará and Mato Grosso states, see discussion below on geographic distribution), including primary female types of <i>P. compressa</i> and <i>P. trimaculata</i>, as conspecific with <i>P. triquetra</i> males. Thus, under the Principle of Priority of the International Code of Zoological Nomenclature (ICZN 1999), the valid name for this species is <i>P. triquetra</i>.</p> <p> <b>Material examined.
