RESUMO
Background: HER-2 positive (+) breast cancer (BC) accounts for 20-25% of BC, it is more aggressive, and it has a lower survival rate. Since the approval of trastuzumab in 1998, other HER-2-targeted therapies such as pertuzumab and trastuzumab emtansine (TDM1) have been introduced, improving patient survival. However, cardiotoxicity is an adverse effect of these treatments. Objective: To estimate the incidence of cardiotoxicity with trastuzumab, trastuzumab/pertuzumab, and TDM1 in women with HER-2 + BC treated over a 6-year period at the Hospital de Clínicas and the Hospital Departamental de Soriano. Material and methods: Observational, descriptive, and retrospective study which included patients with HER-2 + BC treated with trastuzumab, trastuzumab/pertuzumab, or TDM1. Results: 81 patients were included, with a cardiotoxicity incidence of 23.4%. Cardiotoxicity was determined by a > 10% decrease in left ventricular ejection fraction (LVEF) (57.9%) and a LVEF < 50% evident during treatment (42.1%). Only 1 patient presented symptomatic heart failure. 63.1% of those who discontinued treatment due to cardiotoxicity managed to resume it. No relationship was evident between cardiovascular history or the administration regimen and the development of cardiotoxicity. Conclusion: The study showed a cardiotoxicity incidence similar to the international one. Most did not present cardiac toxicity, and if they did, it was asymptomatic and reversible.
Introducción: el cáncer de mama (CM) HER-2 positivo (+) representa el 20-25% de los CM, es más agresivo y tiene menor sobrevida. Desde la aprobación del trastuzumab en 1998, se han introducido otras terapias dirigidas al HER-2 como pertuzumab y trastuzumab emtansina (TDM1), con lo cual ha mejorado la supervivencia de las pacientes. Sin embargo, la cardiotoxicidad representa un efecto adverso de estos tratamientos. Objetivo: estimar la incidencia de cardiotoxicidad con trastuzumab, trastuzumab/pertuzumab y TDM1 en mujeres con CM HER-2 +, tratadas en un periodo de 6 años en el Hospital de Clínicas y el Hospital Departamental de Soriano. Material y métodos: estudio observacional, descriptivo y retrospectivo que incluyó pacientes con CM HER-2 +, tratadas con trastuzumab, trastuzumab/pertuzumab o TDM1. Resultados: se incluyeron 81 pacientes. La incidencia de cardiotoxicidad fue del 23.4%. La cardiotoxicidad se determinó por una disminución > 10% de la fracción de ejección del venticulo izquierdo (FEVI) (57.9%) y por una FEVI < 50%, evidenciada durante el tratamiento (42.1%). Únicamente una paciente presentó insuficiencia cardiaca sintomática. El 63.1% de quienes suspendieron el tratamiento por cardiotoxicidad logró reanudarlo. No se evidenció una relación entre los antecedentes cardiovasculares ni con el esquema de administración y el desarrollo de cardiotoxicidad. Conclusión: el estudio mostró una incidencia de cardiotoxicidad similar a la internacional. La mayoría no tuvo toxicidad cardiaca y si la hubo fue asintomática y reversible.

The use of creatine monohydrate (Cr) in professional soccer is widely documented. However, the effect of low doses of Cr on the physical performance of young soccer players is unknown. This study determined the effect of a low dose of orally administered Cr on muscle power after acute intra-session fatigue in young soccer players. Twenty-eight young soccer players (mean age = 17.1 ± 0.9 years) were randomly assigned to either a Cr (n = 14, 0.3 g·kg-1·day-1 for 14 days) or placebo group (n = 14), using a two-group matched, double-blind, placebo-controlled design. Before and after supplementation, participants performed 21 repetitions of 30 m (fatigue induction), and then, to measure muscle power, they performed four repetitions in half back squat (HBS) at 65% of 1RM. Statistical analysis included a two-factor ANOVA (p Ë 0.05). Bar velocity at HBS, time: p = 0.0006, Åp2 = 0.22; group: p = 0.0431, Åp2 = 0.12, time × group p = 0.0744, Åp2 = 0.02. Power at HBS, time: p = 0.0006, Åp2 = 0.12; group: p = 0.16, Åp2 = 0.06, time × group: p = 0.17, Åp2 = 0.009. At the end of the study, it was found that, after the induction of acute intra-session fatigue, a low dose of Cr administered orally increases muscle power in young soccer players.

OBJECTIVE: To develop updated guidelines for the pharmacological management of rheumatoid arthritis (RA). METHODS: A group of experts representative of different geographical regions and various medical services catering to the Mexican population with RA was formed. Questions based on Population, Intervention, Comparison, and Outcome (PICO) were developed, deemed clinically relevant. These questions were answered based on the results of a recent systematic literature review (SLR), and the evidence's validity was assessed using the GRADE system, considered a standard for these purposes. Subsequently, the expert group reached consensus on the direction and strength of recommendations through a multi-stage voting process. RESULTS: The updated guidelines for RA treatment stratify various therapeutic options, including different classes of DMARDs (conventional, biologicals, and JAK inhibitors), as well as NSAIDs, glucocorticoids, and analgesics. By consensus, it establishes the use of these in different subpopulations of interest among RA patients and addresses aspects related to vaccination, COVID-19, surgery, pregnancy and lactation, and others. CONCLUSIONS: This update of the Mexican guidelines for the pharmacological treatment of RA provides reference points for evidence-based decision-making, recommending patient participation in joint decision-making to achieve the greatest benefit for our patients. It also establishes recommendations for managing a variety of relevant conditions affecting our patients.

Functional autonomy (FA) is a critical factor in determining the quality of life of older adults (OA), especially in the case of older women (OW), as they face a decline in FA in their later years of life. FA should be assessed early, using valid, reliable, and low-cost tests. This study evaluated the test-retest reliability of GDLAM and GDLAM autonomy index (GI) in OW. Thirty-nine OW (71.2 ± 6.50 years) participated in the study. A repeated measures design was used to compare the interday test-retest reliability of the five GDLAM tests (seconds) and the GI (points). The five tests represent activities of daily living, such as dressing or wandering around the house, while the GI provides a weighting of the results of the five tests. The analysis consisted of the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and coefficient of variation (CV). A CV ≤ 10% and an ICC ≥ 0.80 were considered acceptable reliability, whereas a CV ≤ 5% and an ICC ≥ 0.90 were considered high reliability. The outcome of the five tests, represented by the GI, showed high interday test-retest reliability (CV = 6.00% and ICC = 0.91). The results of this study demonstrate that the five tests of the GDLAM protocol and the GI have high interday test-retest reliability and good interday reproducibility. From a practical point of view, the GDLAM protocol allows the assessment of FA of community-dwelling OW, providing background for early diagnosis and, with it, the possibility of developing an individualized physical exercise prescription.

Los mucoceles son lesiones de extravasación salival asociados a la ruptura de los conductos que generalmente se asocian con trauma. Son azuláceos, con aspecto traslúcido, fluctuantes a la palpación, expansivos y de crecimiento rápido. Mayoritariamente se manifiestan en población joven. El sitio más común de localización es la mucosa de labio inferior, sin embargo, pueden presentarse en cualquier zona que contenga glándulas salivales menores, como vientre de lengua, donde se encuentran las glándulas Blandin-Nuhn. La frecuencia de las lesiones asociadas a éstas glándulas es del 2.25% reportándose aproximadamente 400 casos hasta la fecha. La finalidad de ésta publicación es la descripción de una patología infrecuente, así como realizar una revisión a la literatura. Se presenta el caso de una niña de tres años con historia de aumento de volumen congénito en el dorso de la lengua sin síntomas compatibles con mucocele, se realiza biopsia excisional bajo anestesia general. El resultado del estudio histopatológico reporta: fenómeno de extravasación de mucosa. Paciente evoluciona satisfactoriamente. Estas lesiones expansivas pueden repercutir en el desenvolvimiento normal de la vida de las personas causando dislalia, disfagia y disnea. El tratamiento de este tipo de lesiones en la infancia favorece a un adecuado desarrollo del habla y mejora las condiciones de alimentación.
Mucoceles are salivary extravasation lesions associated with rupture of ducts that are generally associated with trauma. They are bluish, translucent in appearance, fluctuating on palpation, expansive and fast growing. They mostly occur in young people. The most common site of location is the mucosa of the lower lip, however, they can occur in any area that contains minor salivary glands, such as the belly of the tongue, where the Blandin-Nuhn glands are located. The frequency of lesions associated with Blandin-Nuhn's glands is 2.25%, with approximately 400 cases reported to date. The purpose of this publication is the description of an uncommon pathology, as well as a review of the literature. The case of a three-year-old female with a history of congenital volume increase at the dorsum of the tongue without symptoms compatible with mucocele is reported, an excisional biopsy was performed under general anesthesia. The result of the histopathological study reports: extravasation mucus phenomenon. Patient evolves satisfactorily. These expansive lesions can affect the normal development of people's lives, causing dyslalia, dysphagia and dyspnea. Treatment of this type of injuries in childhood favors adequate speech development and improves feeding conditions.
RESUMO
Background and Aims: Due to increased urbanization and industry, environmental pollution is a serious public health concern. Globally, the quality of life is particularly lowered by exposure to high amounts of particulate matter (PM). Chile has five industrial zones with high pollution levels, called "sacrifice zones." However, the effect of polluted air on the quality of life and functional autonomy (FA) of older people living in industrial zones with high pollution levels is unknown. Therefore, this study aimed to determine the quality of life and FA differences between Chilean older women (OW) living in areas with lower and higher PM levels. Materials and Methods: Seventy-two OW volunteered for this study. The sample was divided into Zone 1 (PM2.5 ≤ 15 µg/m3, n = 36) and Zone 2 (PM2.5 > 15 µg/m3, n = 36). The variables were quality of life-assessed through the SF-36v2.0 questionnaire, and FA-assessed through the GDLAM protocols. Differences between zones were tested by Student's t-test and Mann-Whitney test, both for independent samples (p < 0.05). Results: All eight dimensions of quality of life were lower in Zone 2, of which the role emotional (RE) showed significant differences between zones (p < 0.05). Performance on the GDLAM protocols and the FA index were lower in Zone 2 (p Ë 0.05). Conclusion: OW in Zone 2 showed lower quality of life and FA. PM could affect the older population's physical and mental health and, therefore, the quality of life.
RESUMO
Introducción. El edema pulmonar por reexpansión es una complicación poco frecuente, secundaria a una rápida reexpansión pulmonar posterior al drenaje por toracentesis o toracostomía cerrada. Al día de hoy, se ha descrito una incidencia menor al 1 % tras toracostomía cerrada, con mayor prevalencia en la segunda y tercera década de la vida. Su mecanismo fisiopatológico exacto es desconocido; se ha planteado un proceso multifactorial de daño intersticial pulmonar asociado con un desequilibrio de las fuerzas hidrostáticas. Caso clínico. Presentamos el caso de un paciente que desarrolló edema pulmonar por reexpansión posterior a toracostomía cerrada. Se hizo una revisión de la literatura sobre esta complicación. Resultados. Aunque la clínica sugiere el diagnóstico, la secuencia de imágenes desempeña un papel fundamental. En la mayoría de los casos suele ser autolimitado, por lo que su manejo es principalmente de soporte; sin embargo, se han reportado tasas de mortalidad que alcanzan hasta el 20 %, por tanto, es importante conocer los factores de riesgo y las medidas preventivas. Conclusión. El edema pulmonar de reexpansión posterior a toracostomía es una complicación rara en los casos con neumotórax, aunque es una complicación que se puede presentar en la práctica diaria, por lo cual debe tenerse en mente para poder hacer el diagnóstico y un manejo adecuado.
Introduction. Re-expansion pulmonary edema is a rare complication secondary to rapid pulmonary re-expansion after drainage by thoracentesis and/or closed thoracostomy. As of today, an incidence of less than 1% has been described after closed thoracostomy, with a higher prevalence in the second and third decades of life. Its exact pathophysiological mechanism is unknown; a multifactorial process of lung interstitial damage associated with an imbalance of hydrostatic forces has been proposed. Clinical case. We present the case of a patient who developed pulmonary edema due to re-expansion after closed thoracostomy, conducting a review of the literature on this complication. Results. Although the clinic suggests the diagnosis, the sequence of images plays a fundamental role. In most cases, it tends to be a self-limited disease, so its management is mainly supportive. However, mortality rates of up to 20% have been recorded. Therefore, it is important to identify patients with major risk factors and initiate preventive measures in these patients. Conclusions. Re-expansion pulmonary edema after thoracostomy is a rare complication in cases with pneumothorax; however, it is a complication that can occur in daily practice. Therefore, it must be kept in mind to be able to make the diagnosis and an adequate management.

BACKGROUND: The global beef market demands the meat industry to ensure product quality and safety in markets that are often very distant. The present study aimed to evaluate the effects of chilled (CH, 120 d) and chilled-then-frozen (CHF, 28 d + 92 d) storage conditions of beef vacuum packaged (VP) and vacuum packaged with antimicrobial (VPAM) on meat quality, oxidative status and microbial loads. Treatments resulted from the combination of storage condition and packaging type: VP + CH, VP + CHF, VPAM + CH and VPAM + CHF. RESULTS: Warner-Bratzler shear force values decreased in all treatments after 28 d of chilling. Except for VP + CH, L* values (lightness) of meat color did not differ in each treatment as the storage time increased. Meat from VP + CH had greater a* values than CHF treatments on day 120 of storage. A consumer panel did not detect differences in tenderness, flavor and overall liking between VP and VPAM beef, but they preferred CHF steaks rather than CH beef. TBARS values did not differ between VP and VPAM and between CH and CHF at any time during the storage period. At the end of storage time, all treatments except VP + CHF presented a greater concentration of thiols than at 48 h post-mortem. On day 120 of storage, VP + CH had greater catalase enzyme activity than CHF treatments while VP + CH and VP + CHF showed a greater superoxide dismutase activity than VPAM + CHF. Storage condition (CH or CHF) had a greater impact on microbial counts than the type of packaging. CONCLUSION: Freezing meat after an ageing period represents a suitable strategy to extend beef storage life without a detrimental impact on its quality. © 2023 The Authors.

En Uruguay existe una desigual distribución de médicos entre la capital y el resto del país, determinando que los pacientes deban ser referidos a centros asistenciales fuera del área en la que residen. El Proyecto ECHO (del inglés: Extension for Community Healthcare Outcomes) busca mejorar el acceso a atención especializada para poblaciones rurales mediante la utilización de tecnologías de la comunicación, democratizando el conocimiento. Objetivo: evaluar los resultados en lo referente a competencias y habilidades profesionales en los participantes de las teleclínicas ECHO sobre cáncer ginecológico en Uruguay. Método: evaluación retrospectiva de impacto con línea de base y línea de impacto mediante un censo vía web. Período: setiembre 2020- mayo/2021. Se relevaron 22 variables, 14 indicadores dependientes que miden autopercepciones sobre incremento de capacidades en forma retrospectiva a partir de una escala Likert de 5 valores y, 8 independientes que abordan aspectos generales de la población. Teniendo en cuenta que no hay una distribución normal se aplica el test no paramétrico de Wilkoxon. Resultados: se obtuvieron 36 respuestas. Los resultados, muestran que todos los pares tienen una significación bilateral, pudiendo afirmar que existe una diferencia significativa entre las capacidades previas y posteriores a la participación en el programa ECHO. Conclusiones: se objetiva una mejora en la autopercepción de las capacidades de los participantes luego de la implementación de las teleclínicas ECHO.
In Uruguay there is an unequal distribution of doctors between the capital and the rest of the country, determining that patients must be referred to healthcare centers outside the area in which they reside. The ECHO (Extension for Community Healthcare Outcomes) Project seeks to improve access to specialized care for rural populations through the use of communication technologies, democratizing knowledge. Objective: to evaluate the results regarding professional competencies and skills in the participants of the ECHO teleclinics on gynecological cancer in Uruguay. Method: retrospective impact evaluation with baseline and impact line through a web census. Period: September 2020- May/2021. 22 variables were surveyed, 14 dependent indicators that measure self-perceptions of increased capabilities retrospectively based on a Likert scale of 5 values, and 8 independent indicators that address general aspects of the population. Taking into account that there is no normal distribution, the non-parametric Wilkoxon test is applied. Results: 36 responses were obtained. The results show that all pairs have a bilateral significance, being able to affirm that there is a significant difference between the capabilities before and after participation in the ECHO program. Conclusions: an improvement in the self-perception of the participants' capabilities was observed after the implementation of the ECHO teleclinics.

A good muscle quality index (MQI) may have an inverse relationship with psychosocial variables of depression, anxiety, and stress in adolescents. Unfortunately, little scientific evidence has related MQI to psychosocial variables in this population. Therefore, this research aimed to determine the relationship between the MQI and psychosocial variables of depression, anxiety, and stress in Chilean adolescents. In this quantitative correlational design study, sixty adolescents participated voluntarily (mean ± standard deviation [SD]: age 15.11 ± 1.78 years). Anthropometric parameters, prehensile strength, MQI, and psychosocial variables were evaluated. The results showed that adolescents with high levels of MQI presented lower levels of depression (7.50 ± 6.06 vs. 10.97 ± 5.94), anxiety (5.64 ± 4.81 vs. 9.66 ± 5.12), and stress (6.79 ± 5.09 vs. 10 ± 5.58), in addition to reported lower abdominal obesity (WtHR, 0.47 ± 0.07 vs. 0.52 ± 0.07) than those with low levels of MQI. The group with high levels of MQI reported a higher prevalence of nonanxiety (81.3%, p = 0.031) and a lower prevalence of abdominal obesity (55.8%, p = 0.023). Likewise, a significant inverse association was evidenced between MQI and depression (ß; -6.18, 95% CI; -10.11: -2.25, p = 0.003), anxiety (ß; -6.61, 95% CI; -9.83: -3.39, p < 0.001) and stress (ß; -4.90, 95% CI; -8.49: -1.32 p = 0.008). In conclusion, the results suggest that high levels of MQI are associated with a higher prevalence of nonanxiety in adolescents and a significant inverse association between MQI and levels of depression, anxiety, and stress.
