Validity of the ROX index in predicting invasive mechanical ventilation requirement in pneumonia.

Background: The ROX index (espiratory rate-ygenation) has been described as a prediction tool to identify the need for invasive mechanical ventilation (IMV) in community-acquired pneumonia (CAP) with acute hypoxaemic respiratory failure treated with high-flow nasal cannula in order to avoid delay of a necessary intubation. However, its use in predicting the need for ventilatory support in hospitalised patients with CAP has not been validated.

Methods: This is a retrospective cohort study including subjects with CAP treated in the general ward, emergency service or intensive care unit of a third-level centre in Cundinamarca, Colombia, between January 2001 and February 2020.

Performance of the CORB (Confusion, Oxygenation, Respiratory Rate, and Blood Pressure) Scale for the Prediction of Clinical Outcomes in Pneumonia.

Background: Community-acquired pneumonia (CAP) is a common cause of morbidity and mortality due to misdiagnosis and inappropriate treatment approaches.

Objective: To assess the performance of the CORB score in subjects with CAP for predicting in-hospital mortality, death within 30 days of admission, and requirement for invasive mechanical ventilation (IMV) and vasopressor support.

Methods: A retrospective, cohort study with diagnostic test analysis of CORB and CURB-65 scores in subjects with CAP according to ATS criteria was undertaken.

Influence of Implant Design and Under-Preparation of the Implant Site on Implant Primary Stability. An In Vitro Study.

The aim of this study was to evaluate the effects of different implant sites an under-preparation sequence associated with two different implant designs on implant primary stability measured by two parameters: insertion torque (IT) and implant stability quotient (ISQ). It used two different implants: one cylindrical as a control and another one with a tapered design. The implants were inserted in type III fresh humid bovine bone and four drilling sequences were used: one control, the one proposed by the implant company (P1), and three different undersized (P2, P3 and P4).

Laser-induced fluorescence in the diagnosis of pulp exposure and the influence of residual dentin thickness: An in vivo study.

Purpose: To clinically (a) determine whether laser-induced fluorescence (LIF) was able to assess pulp tissue health or disease in situations of pulp exposure; (b) evaluate the influence of different pulp tissue conditions upon LIF through dentin thicknesses of ≤1 mm; and (c) explore possible differences between the diagnostic performance of quantitative (q) and qualitative (ql) LIF.

Methods: 98 healthy subjects were scheduled for the treatment of caries. Three groups were established according to pulp tissue condition: Group A (n=30 teeth) (deep caries with healthy pulp tissue); Group B (n=30 teeth) (pulp necrosis); and Group C (n=30 teeth) (irreversible symptomatic acute pulpitis).

Home and abroad: vets' role in dealing with rabies.

Manuela Herrera reports on a session at the BVA Congress which discussed the contributions that vets can make to tackling rabies, and how the profession can be at the forefront of a One Health approach to saving the lives of animals and people.

Systematics of the oswaldoi complex (Anopheles, Nyssorhynchus) in South America.

Background: Effective malaria control relies on accurate identification of those Anopheles mosquitoes responsible for the transmission of Plasmodium parasites. Anopheles oswaldoi s.l.

Assessing the need for future veterinary surgeons.

While some in the profession are concerned about a possible 'overproduction' of vets, others argue that more might be needed to help meet current and future challenges. A debate at this year's BVA Congress tackled the question of how many vets are required, while considering how their unique skills might be more widely applied. Manuela Herrera reports.

Improving work-life balance: what can employers and employees do?

Effective time management can play a big part in reducing stress for busy vets, but too often miscommunication between practice employers and employees can make it harder to achieve a good work-life balance. Manuela Herrera reports on a session at the BVA Congress which considered what vets can do to facilitate better time management in practice.

[Anopheles species present in the department of Putumayo and their natural infectivity with Plasmodium].

Introduction: Putumayo is considered an endemic region for malaria transmission, mainly due to Plasmodium vivax. The vectors in this region are Anopheles darlingi , which has been found only in the municipality of Puerto Leguízamo, and An. rangeli and An.

Critical diameter of apical foramen and of file size using the Root ZX apex locator: an in vitro study.

Introduction: An evaluation was made of the accuracy of the Root ZX apex locator (J. Morita Corp, Tokyo, Japan) in widened foramina, considering the existing controversy over this issue in the literature.

Methods: Ten single-root teeth were embedded in an alginate mold.

Molecular comparison of topotypic specimens confirms Anopheles (Nyssorhynchus) dunhami Causey (Diptera: Culicidae) in the Colombian Amazon.

The presence of Anopheles (Nyssorhynchus) dunhami Causey in Colombia (Department of Amazonas) is confirmed for the first time through direct comparison of mtDNA cytochrome c oxidase I (COI) barcodes and nuclear rDNA second internal transcribed spacer (ITS2) sequences with topotypic specimens of An. dunhami from Tefé, Brazil. An.

Influence of apical constriction diameter on Root ZX apex locator precision.

Small-diameter hand files are systematically used to determine the initial working length and to establish patency of the root canal. In wide canals, electronic apex locator accuracy might be influenced by file size. This article reports on a study to assess the influence of apical constriction diameter on the precision of the Root ZX apex locator by using files of varying diameter on teeth with 3 different degrees of apical widening: 0.
