Plate tectonics, cold adaptation and long-distance range expansion to remote archipelagos and the high Andes as drivers of a circumantarctic freshwater arthropod radiation.

Disjunct distributions, characterised by spatially separated populations of related species, offer insights into historical biogeographic patterns and evolutionary processes. This study investigates the evolutionary history of the diving beetle subfamily Lancetinae through a phylogenomic approach incorporating ultraconserved elements (UCEs) and heritage genetic markers. Our findings support an early Miocene origin for Lancetinae, with subsequent diversification influenced by historical vicariance events and long-distance dispersal.

Radiofrequency ablation as a novel modality in Ecuador for treating toxic thyroid nodules: a case series.

Background: Treating hyperthyroidism induced by autonomously functioning thyroid nodules (AFTNs) through radioactive iodine and surgery often results in undesirable hypothyroidism. Radiofrequency ablation (RFA) has arisen as a favorable option. European guidelines recommend RFA for small AFTN in young patients, aiming to restore normal thyroid function and avoid irradiation.

Radiofrequency ablation for thyroid nodules in Ecuador: a cross-sectional study.

Objectives: To describe the demographic characteristics and clinical outcomes following the first cohort of patients with Bening Thyroid Nodule (BTN) and (Papillary Thyroid Microcarcinoma) (PTMC) treated with Radiofrequency Ablation (RFA)in Ecuador.

Methods: Single-center, cross-sectional study. We included adults undergoing RFA for BTN and PTMC between July 2019 and May 2022.

Therefore, we sought a meta-analysis and systematic review comparing the rates and types of appendiceal neoplasm between complicated and uncomplicated appendicitis.

Methods: We included articles published from the time of inception of the datasets to September 30, 2022.

Ablation techniques or active surveillance compared to surgical resection in patients with low-risk papillary thyroid cancer: a systematic review and meta-analysis.

Background: The global prevalence of thyroid cancer is on the rise. About one-third of newly diagnosed thyroid cancer cases comprise low-risk papillary thyroid cancer (1.5 cm or more minor).

Surgical approach for thyroglossal duct cyst cancer: a case report of challenging conventional thinking.

This article reports an older woman with a 2-year history of enlarging submental neck mass. Head and neck imaging displayed a group with a solid central component. Additionally, a fine-needle aspiration suggested neoplasia.

Robotic right versus left colectomy for colorectal neoplasia: a systemic review and meta-analysis.

Previous studies comparing right and left colectomies have shown variable short-term outcomes. Despite the rapid adoption of robotics in colorectal operations, few studies have addressed outcome differences between robotic right (RRC) and left (RLC) colectomies. Therefore, we sought to compare the short-term outcomes of RRC and RLC for neoplasia.

Relationship between lean manufacturing tools and their sustainable economic benefits.

Unlabelled: Traditionally, the isolated relationship of total preventive maintenance (TPM), quick setup (QS), overall equipment effectiveness (OEE), and one-piece flow (OPF) with economic sustainability (ESU) has been investigated; however, these lean manufacturing (LM) tools are implemented together into production systems, and traditional research does not report their relationships and interactions. To contribute to this gap, this paper integrates all those variables in a structural equation model (SEM), which are related by seven hypotheses that are validated using the partial least squares (PLS) technique using information from 176 responses to a questionnaire applied to the Mexican maquiladora industry. Additionally, a sensitivity analysis has been carried out to determine the probability of occurrence at high and low implementation levels for all variables when they occur in isolation, jointly and conditionally.

Intussusception and COVID19, Successful Mechanic Reduction, Case Report.

The COVID 19 pandemic has greatly affected the world population. SARS CoV2 infection in pediatric patients is related to the development of mild symptoms and in some cases gastrointestinal manifestations. We present the case of a patient with intussusception as a manifestation associated with SARS CoV2 infection, treated by ultrasound-guided hydrostatic reduction with successful results.

Novel Coronavirus Infection in an Infant with Intussusception.

. Intussusception is the leading cause of intestinal obstruction in children under 4 years of age. Viral infections are the associated etiology in most cases, SARS-CoV-2 thereby being a plausible cause, although only 5 cases have been reported worldwide with both entities.

Assessment of the bacterial diversity of agave sap concentrate, resistance to in vitro gastrointestinal conditions and short-chain fatty acids production.

Low bacterial diversity in the gut has been associated with the development of several diseases. Agave sap concentrate (ASC) is obtained from the thermal treatment of the fresh sap called "aguamiel", an artisanal Mexican food. In this study, we assessed the microbial diversity from three different ASC producing regions in Mexico using high-throughput sequencing of the 16S rRNA gene and evaluated their resistance to an in vitro gastrointestinal process as well as their ability to produce short-chain fatty acids (SCFA).

Telehealth in Colombia, challenges associated with COVID-19.

The COVID-19 pandemic has generated a revolution of such magnitude that no aspect of human life will be the same from now on. The provision of health services and health education are not unrelated to this new normality imposed by the disease, and its consequences have been reflected in the need to use protocols and resources based on virtuality that most of us had not valued in their real dimension. Telehealth and telemedicine will be basic tools for professionals and teachers and it is our obligation to know them, apply them, and innovate to adapt to this reality.

Experiences of parents and/or caretakers of children with Hirschsprung’s disease or anorectal malformations during follow-up after pediatric surgery.

Introduction: Hirschsprung’s disease and anorectal malformations are pathologies that affect the pediatric population and compromise life from birth, making diagnosis and early treatment essential. The comorbidities they lead to in the long-term take parents and caretakers to situations that, without proper accompaniment, can generate serious complications in the child. Objective: To describe the meaning of the experiences of parents of children with Hirschsprung’s disease or anorectal malformations who have had surgical treatment and are being followed-up.

Decreased Metabolic Rate in the Mole Crabs, Emerita analoga, Infected with the Acanthocephalan Profilicollis altmani.

The relationship between a parasite and its host will have an energy cost for the host at some point; however, this basic hypothesis has seldom been evaluated. Using Emerita analoga as a model species, we investigated the aerobic metabolism, ammonia excretion rate, and locomotor performance patterns of crabs both uninfected and infected with the acanthocephalan Profilicollis altmani. Our results show that infected Emerita had a lower metabolic rate compared to uninfected ones.

Structural characterization of amphiphilic siderophores produced by a soda lake isolate, Halomonas sp. SL01, reveals cysteine-, phenylalanine- and proline-containing head groups.

Soap Lake, located in Washington State, is a naturally occurring saline and alkaline lake. Several organisms inhabiting this lake have been identified as producers of siderophores that are unique in structure. Bacterial isolates, enriched from Soap Lake sediment and water samples, were screened for siderophore production using both the chrome azurol S (CAS) agar plate and liquid methods.

3-Nitroasterric Acid Derivatives from an Antarctic Sponge-Derived Pseudogymnoascus sp. Fungus.

Four new nitroasterric acid derivatives, pseudogymnoascins A-C (1-3) and 3-nitroasterric acid (4), along with the two known compounds questin and pyriculamide, were obtained from the cultures of a Pseudogymnoascus sp. fungus isolated from an Antarctic marine sponge belonging to the genus Hymeniacidon. The structures of the new compounds were determined by extensive NMR and MS analyses.

Management of early-stage esophageal neoplasia (MESEN) consensus.

Background: Treatment of esophageal adenocarcinoma often involves surgical resection. Newer technologies in interventional endoscopy have led to a substantial paradigm shift in the management of early-stage neoplasia in Barrett's esophagus comprising high-grade dysplasia (HGD), intramucosal carcinoma, and, in some cases, submucosal carcinoma. However, there has been no consensus regarding the indications for esophageal preservation in these cases.
