Mobile Health–Based Thermometer for Monitoring Wound Healing After Endovascular Therapy in Patients With Chronic Foot Ulcer: Prospective Cohort Study
Authors: Lin Donna Shu-Han , Lee Jen-Kuang 
Published: May 2021

Background
Foot temperature may increase after endovascular therapy, but the relationship between foot temperature and wound healing is unclear.

Objective
This study was performed to evaluate the feasibility of a mobile health (mHealth)–based thermometer for foot temperature monitoring in patients with chronic foot ulcer before and after endovascular therapy and to determine the association between temperature change and wound healing time.

Methods
This was a prospective cohort study. Patients who had a chronic foot ulcer (>3 months) and underwent endovascular therapy between July 2019 and December 2019 were included. The participants received standard medical care and endovascular therapy for revascularization. The mHealth-based thermometer, composed of 4 temperature-sensing chips, was put on the foot before and after endovascular therapy. Data from the chips were transferred to an associated mobile phone app via Bluetooth. Wound healing time was estimated using the Kaplan-Meier method, and the associations between baseline characteristics and clinical outcomes were evaluated using a Cox proportional hazard model.

Results
A total of 163 patients with chronic foot ulcer who underwent endovascular therapy were enrolled and followed up until wound healing was complete or for 180 days. The mean foot temperature before endovascular therapy was 30.6 (SD 2.8 °C). Foot temperature increased significantly (mean 32.1 °C, SD 2.8 °C; P=.01) after the procedure. Wound healing time was significantly different in the Kaplan-Meier curves of the patient group with temperature changes ≥2 °C and the group with temperature changes ≤2 °C (log-rank P<.001). A foot temperature increase ≥2 °C after endovascular therapy was associated with increased wound healing in univariate analysis (hazard ratio [HR] 1.78, 95% CI 1.24-2.76, P=.02), and the association remained significant in multivariate analysis (HR 1.69, 95% CI 1.21-2.67, P=.03).

Conclusions
The mHealth-based thermometer was feasible and useful for foot temperature monitoring, which may provide health care professionals with a new endpoint for endovascular therapy. Foot temperature increases ≥2 °C after endovascular therapy were associated with faster wound healing in patients with chronic foot ulcer. Further studies are needed, however, to confirm these findings.
Diagnostic Accuracy of Artificial Intelligence and Computer-Aided Diagnosis for the Detection and Characterization of Colorectal Polyps: Systematic Review and Meta-analysis
Authors: Nazarian Scarlet , Glover Ben , Ashrafian Hutan , Darzi Ara , Teare Julian 
Published: May 2021

Background
Colonoscopy reduces the incidence of colorectal cancer (CRC) by allowing detection and resection of neoplastic polyps. Evidence shows that many small polyps are missed on a single colonoscopy. There has been a successful adoption of artificial intelligence (AI) technologies to tackle the issues around missed polyps and as tools to increase the adenoma detection rate (ADR).

Objective
The aim of this review was to examine the diagnostic accuracy of AI-based technologies in assessing colorectal polyps.

Methods
A comprehensive literature search was undertaken using the databases of Embase, MEDLINE, and the Cochrane Library. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed. Studies reporting the use of computer-aided diagnosis for polyp detection or characterization during colonoscopy were included. Independent proportions and their differences were calculated and pooled through DerSimonian and Laird random-effects modeling.

Results
A total of 48 studies were included. The meta-analysis showed a significant increase in pooled polyp detection rate in patients with the use of AI for polyp detection during colonoscopy compared with patients who had standard colonoscopy (odds ratio [OR] 1.75, 95% CI 1.56-1.96; P<.001). When comparing patients undergoing colonoscopy with the use of AI to those without, there was also a significant increase in ADR (OR 1.53, 95% CI 1.32-1.77; P<.001).

Conclusions
With the aid of machine learning, there is potential to improve ADR and, consequently, reduce the incidence of CRC. The current generation of AI-based systems demonstrate impressive accuracy for the detection and characterization of colorectal polyps. However, this is an evolving field and before its adoption into a clinical setting, AI systems must prove worthy to patients and clinicians.

Transgresión social y género: notas conceptuales y epistemológicas para una sociología feminista de la transgresión
Authors: Arroyo Gilberto Morales 
Published: May 2021

Este artículo es un primer esfuerzo analítico por constituir una sociología feminista de la transgresión. A partir de la sociología de la desviación, el feminismo y el psicoanálisis, se proponen algunas notas para dotar de contenido teórico y epistemológico a conceptos que nos permitan comprender el fenómeno de la ruptura del orden social caracterizado como la gramática del horror. Primero, se explica la base conceptual de esta propuesta. Después, se debate porque el concepto de desviación es insuficiente para interpretar y comprender la ruptura del orden social. Finalmente, se presenta la propuesta conceptual y temática que debería seguir una sociología que, respecto al fenómeno de la transgresión social, pretenda visibilizar los cuerpos, comportamientos y prácticas de las mujeres. Metodológicamente, se trata de un debate teórico analítico que recurre, ahí donde es necesario, a referentes empíricos del orden social actual en México.
Variantes de la parentalidad de personas de la diversidad sexual y afectiva: el caso de hombres gays y mujeres lesbianas en la Ciudad de México
Authors: Laguna Maqueda Oscar Emilio , Salinas-Quiroz Fernando 
Published: May 2021

El presente escrito conjunta información de dos investigaciones enfocadas en analizar arreglos parentales de padres gais y madres lesbianas en la Ciudad de México. Ambas pesquisas utilizaron estudios de caso instrumentales. Los datos provenientes de las entrevistas fueron interpretados bajo la lupa de la teoría crítica de género. Se identificó que las personas de la diversidad sexual y afectiva tienden a reproducir los mandatos de la cultura de género asociados con la construcción de las familias. No obstante, la respuesta a las exclusiones y discriminaciones derivadas de la homofobia y el homoprejuicio impelen a madres lesbianas y padres gais a desarrollar prácticas parentales que responden a esos vectores de poder y que a su vez reformulan las prácticas de cuidado y crianza tradicionales.

Abstract
The aim of this study was to determine the effects of sodium selenite on the level of oxidative stress and viability of spermatozoa in fresh bull ejaculate in in vitro conditions at different temperatures. Samples of the bull's ejaculates with a concentration of 7 × 105 spermatozoa per ml were placed into the commercial semen extender containing 0 (control), 1 (1Se), 3 (3Se) and 5 (5Se) µg.ml–1 of sodium selenite. The following analyses were performed by flow cytometry after 1, 3, 6, 8, 24, 48 and 72 hours of incubation at 4 °C and 37 °C. All analyses were carried out in triplicate. The level of oxidative stress at both temperatures were significantly lower in the experimental groups in comparison to the control group. However, a significant decline of live sperm concentration and a rise of damaged sperm concentration were recorded, especially in groups 1Se and 3Se in comparison to the control group. Only in group 5Se was there observed a positive effect on the damaged spermatozoa level in comparison with groups C, 1Se and 3Se at 4 °C. In conclusion, the applied concentrations of sodium selenite had a positive effect on the level of oxidative stress in all experimental groups, but mainly at concentration of 5 µg.ml–1 of sodium selenite, especially at 4 °C. However, the effect of selenium was not sufficient for improving the sperm viability.
