Rheological Properties and Antioxidant Activity of Gelatin-Based Edible Coating Incorporating Tomato (Solanum lycopersicum L.) Extract.

Gelatin is a promising biopolymer for edible coatings thanks to its low cost and gelling properties. However, its weak mechanical properties limit its use. This study aimed to develop a gelatin coating with tomato extract, analyzing its antioxidant activity and rheological properties for food applications. Gelatin concentrations (2, 5, and 7%) were evaluated, and it was determined that 7% with 7.5% glycerol was the optimal mixture. Three concentrations of tomato extract (0.5, 1, and 1.5%) were added, and antioxidant activity was evaluated using the ABTS technique, as well as the interaction of components through FT-IR and physicochemical analysis. The results showed that there were no significant differences in terms of their physicochemical characterization, maintaining a pH of 5 and a yellowish hue. The FT-IR spectra indicated there were hydrogen bond interactions between gelatin and the extract. The antioxidant capacity was higher with the 1.5% extract, achieving an inhibition of 58.9%. It was found that the combination of the different materials used improved the rheological (specifically the viscosity and stability of the material) and antioxidant properties of the gelatin. These findings suggest that modified gelatin coatings may be effective in extending the shelf life of foods.

[Anorectal melanoma: Clinical case]. / Melanoma anorrectal: un caso clínico.

Background: Anorectal melanoma (AM) is a rare and aggressive type of tumor, with varied and inconclusive scientific information. Its preoperative diagnosis is challenging due to its rarity and similarity to other anorectal conditions. It represents only 1.3% of melanomas and affects more women than men. Approximately 20-30% of AM cases are amelanotic, complicating endoscopic detection and leading to misdiagnoses. AM is often confused with hemorrhoids, polyps, and rectal cancer in two thirds of patients due to similar symptoms. The causes and risk factors of AM are not well understood, but they are suspected to differ from cutaneous and ocular melanomas. Diagnosis is performed through biopsy and immunohistochemical staining. Colonoscopy helps to characterize the lesions, and histological examination is crucial for definitive diagnosis. Clinical case: 50-year-old woman with rectal bleeding and proctalgia. AM was diagnosed through colonoscopy, and transanal resection with hemorrhoidectomy was performed. Conclusions: Management of AM is complicated by the lack of randomized trials. Resection surgery is the standard treatment, but there is no established protocol. Wide local excision may be an option for limited cases. Further research is needed to improve the management and treatment of AM. Early detection and complete surgical removal are crucial for enhancing survival in these patients.

Introducción: el melanoma anorrectal (MA) es un tipo raro y agresivo de tumor, cuya información científica es variada y poco concluyente. Su diagnóstico preoperatorio es un desafío debido a su rareza y a su similitud con otras afecciones anorrectales. Representa solo el 1.3% de los melanomas y afecta más a mujeres que a hombres. Aproximadamente el 20-30% de los casos de MA son amelanóticos, lo que complica su detección endoscópica y conduce a diagnósticos erróneos. El MA se confunde con hemorroides, pólipos y cáncer de recto en dos tercios de los pacientes debido a síntomas similares. Las causas y factores de riesgo del MA aún no se conocen bien, pero se sospecha que son diferentes de los melanomas cutáneos y oculares. El diagnóstico se realiza mediante biopsia y tinción inmunohistoquímica. La colonoscopía permite caracterizar las lesiones y el examen histológico es crucial para el diagnóstico definitivo. Caso clínico: mujer de 50 años con rectorragia y proctalgia. Se diagnosticó MA mediante colonoscopía y se realizó una resección transanal con hemorroidectomía. Conclusiones: el manejo del MA es complicado por la falta de ensayos aleatorizados. La cirugía de resección es el tratamiento habitual, pero no hay un protocolo establecido. La escisión local amplia puede ser una opción para casos limitados. Se necesita más investigación para mejorar el manejo y tratamiento del MA. La detección temprana y la extirpación quirúrgica completa son cruciales para mejorar la supervivencia en estos pacientes.

The "Little-Old-Lady's Hernia", Obturator Hernia: A Case Report and Literature Review.

Obturator hernias, though rare, are clinically significant abdominal hernias, predominantly affecting elderly, thin women, with an estimated prevalence of less than 1%. The primary treatment involves surgical intervention to reduce and repair the defect, either through laparotomy or laparoscopy, with bowel resection needed in up to 75% of patients. Here, we present the case of an 83-year-old woman presenting with abdominal pain and a history of constipation. An abdominal computed tomography scan demonstrated a left obturator hernia with small bowel obstruction. Successful reduction of the hernia was achieved, albeit requiring intestinal resection via an open surgical approach. Subsequently, the patient achieved complete recovery.

[Association between family functionality and mild cognitive impairment in the family with the elderly]. / Asociación entre funcionalidad familiar y deterioro cognitivo leve en la familia con adulto mayor.

AIM: To determine the association between family functionality and mild cognitive impairment in the family with the elderly. METHODOLOGY: Analytical cross-sectional design in families with geriatric patients. A family with a geriatric patient was considered when at least one of its members was over 60years of age. The comparison groups were the family with a geriatric patient without cognitive impairment and the family with a geriatric patient with mild cognitive impairment determined with the MoCA instrument. Family functionality was evaluated with the family APGAR instrument, which identifies three categories: family functionality, moderate family dysfunction, and severe family dysfunction. Statistical analysis included Chi square and Mann-Whitney test. RESULTS: In the family with a geriatric patient, in the group without cognitive impairment the prevalence of family functionality is 89.7% and in the group with mild cognitive impairment the prevalence of family functionality is 59.3% (MW=4.87, P<.000). CONCLUSION: There is an association between family functionality and mild cognitive impairment.

Pyruvate Oxidation Sustains B Cell Antigen-Specific Activation to Exacerbate MASH.

B cells play a crucial role in the pathogenesis of metabolic dysfunction-associated steatohepatitis (MASH), a severe form of steatotic liver disease that if persistent can lead to cirrhosis, liver failure, and cancer. Chronic inflammation and fibrosis are key features of MASH that determine disease progression and outcomes. Recent advances have revealed that pathogenic B cell-derived cytokines and antibodies promote the development of MASH. However, the mechanisms through which B cells promote fibrosis and the metabolic adaptations underlying their pathogenic responses remain unclear. Here, we report that a subset of mature B cells with heightened cytokine responses accumulate in the liver and promote inflammation in MASH. To meet the increased energetic demand of effector responses, B cells increase their ATP production via oxidative phosphorylation (OXPHOS) fueled by pyruvate oxidation in a B cell receptor (BCR)-specific manner. Blocking pyruvate oxidation completely abrogated the inflammatory capacity of MASH B cells. Accordingly, the restriction of the BCR led to MASH attenuation, including reductions in steatosis, hepatic inflammation, and fibrosis. Mechanistically, BCR restriction decreased B cell maturation, activation, and effector responses in the liver, accompanied by decreased T cell- and macrophage-mediated inflammation. Notably, attenuated liver fibrosis in BCR-restricted mice was associated with lower IgG production and decreased expression of Fc-gamma receptors on hepatic stellate cells. Together, these findings indicate a key role for B cell antigen-specific responses in promoting steatosis, inflammation, and fibrosis during MASH.

The time for recovery of quality of life prior to hospitalization is different in each of the dimensions of quality of life (AU)

Potential biomarkers for fatal outcome prognosis in a cohort of hospitalized COVID-19 patients with pre-existing comorbidities.

The difficulty in predicting fatal outcomes in patients with coronavirus disease 2019 (COVID-19) impacts the general morbidity and mortality due to severe acute respiratory syndrome-coronavirus 2 infection, as it wears out the hospital services that care for these patients. Unfortunately, in several of the candidates for prognostic biomarkers proposed, the predictive power is compromised when patients have pre-existing comorbidities. A cohort of 147 patients hospitalized for severe COVID-19 was included in a descriptive, observational, single-center, and prospective study. Patients were recruited during the first COVID-19 pandemic wave (April-November 2020). Data were collected from the clinical history whereas immunophenotyping by multiparameter flow cytometry analysis allowed us to assess the expression of surface markers on peripheral leucocyte. Patients were grouped according to the outcome in survivors or non-survivors. The prognostic value of leucocyte, cytokines or HLA-DR, CD39, and CD73 was calculated. Hypertension and chronic renal failure but not obesity and diabetes were conditions more frequent among the deceased patient group. Mixed hypercytokinemia, including inflammatory (IL-6) and anti-inflammatory (IL-10) cytokines, was more evident in deceased patients. In the deceased patient group, lymphopenia with a higher neutrophil-lymphocyte ratio (NLR) value was present. HLA-DR expression and the percentage of CD39+ cells were higher than non-COVID-19 patients but remained similar despite the outcome. Receiver operating characteristic analysis and cutoff value of NLR (69.6%, 9.4), percentage NLR (pNLR; 71.1%, 13.6), and IL-6 (79.7%, 135.2 pg/mL). The expression of HLA-DR, CD39, and CD73, as many serum cytokines (other than IL-6) and chemokines levels do not show prognostic potential, were compared to NLR and pNLR values.

Objective: To identify the factors associated with adherence to drug therapy among patients with type 2 diabetes mellitus without hypertension. Materials and methods: A cross-sectional, analytical study conducted with patients with type 2 diabetes mellitus without hypertension, divided into an adherent group (n = 145) and a non-adherent group (n = 49), determined by the 4-item Morisky Medication Adherence Scale (MMAS-4). The associated factors were sex, cohabitation, schooling, occupation, age in 10-year groups and diabetes progression time grouped in less than 1 year, from 1 to 5 years, from 6 to 10 years and more than 10 years. The statistical analysis plan included the chi-square test. Results: The factors associated with adherence to drug therapy were identified as sex (p = 0.045), cohabitation (p = 0.045), age (p = 0.001) and disease progression time (p = 0.001). Schooling was not identified as a factor associated with adherence to drug therapy among patients with type 2 diabetes mellitus (p = 0.289). The older the patient with diabetes, the lower the adherence to drug therapy; the cut-off point was 60 years of age, after which the percentage in the non-adherent group was higher than in the adherent group (p = 0.001). The longer the diabetes progression time, the lower the probability of adherence; in the non-adherent group the percentage of patients with more than 10 years of disease progression was 67.3 % and in the adherent group the percentage was 33.8 % (p = 0.001). Conclusions: The factors associated with adherence to drug therapy among patients with type 2 diabetes mellitus without hypertension were identified

Testicular Evaluation Using Shear Wave Elastography (SWE) in Patients with Varicocele.

PURPOSE: To assess the possible influence of the presence of varicocele on the quantification of testicular stiffness. METHODS: Ultrasound with shear wave elastography (SWE) was performed on 48 consecutive patients (96 testicles) referred following urology consultation for different reasons. A total of 94 testes were studied and distributed in three groups: testes with varicocele (group A, n = 19), contralateral normal testes (group B; n = 13) and control group (group C, n = 62). Age, testicular volume and testicular parenchymal tissue stiffness values of the three groups were compared using the Kruskal-Wallis test. RESULTS: The mean age of the patients was 42.1 ± 11.1 years. The main reason for consultation was infertility (64.6%). The mean SWE value was 4 ± 0.4 kPa (kilopascal) in group A, 4 ± 0.5 kPa in group B and 4.2 ± 0.7 kPa in group C or control. The testicular volume was 15.8 ± 3.8 mL in group A, 16 ± 4.3 mL in group B and 16.4 ± 5.9 mL in group C. No statistically significant differences were found between the three groups in terms of age, testicular volume and tissue stiffness values. CONCLUSION: Tissue stiffness values were higher in our control group (healthy testicles) than in patients with varicocele.

Cesárea a solicitud materna

La cesárea es una intervención que salva vidas y que tiene indicaciones médicas. La cesárea está clínicamente indicada cuando existe un riesgo significativo de consecuencias adversas para la gestante o el feto. Sin embargo, en los últimos años se han presentado indicaciones no médicas para la cesárea, como es la cesárea por solicitud materna. Se hace una revisión no sistemática sobre la cesárea a solicitud materna. El parto por cesárea a solicitud de la madre en comparación con el parto vaginal planificado es un tema multifacético y complejo, los datos son mínimos y en su mayoría se basan en comparaciones indirectas, desconociéndose sus implicaciones para las mujeres en edad fértil, los profesionales de la salud y la sociedad. Para los médicos, practicar una cesárea por razones no médicas es una decisión profesional, cuya ética se está debatiendo sin pruebas suficientes sobre los riesgos y los beneficios.

Cesarean section is a life-saving intervention with medical indications. Cesarean section is clinically indicated when there is a significant risk of adverse consequences for the pregnant woman or the fetus. However, in recent years non-medical indications for cesarean section such as cesarean section by maternal request have emerged. This is a non-systematic review of cesarean section at maternal request. Cesarean delivery at mother's request compared to planned vaginal delivery is a multifaceted and complex issue, the data are minimal and mostly based on indirect comparisons, and its implications for women of childbearing age. health professionals and society are unknown. For physicians, performing cesarean section for non-medical reasons is a professional decision, the ethics of which is being debated without sufficient evidence on the risks and benefits.

Complicaciones hemorrágicas y trombóticas del embarazo: diagnóstico, prevención y tratamiento

Las hemorragias y la enfermedad tromboembólica venosa (ETEV) figuran entre las cinco causas más frecuentes de morbilidad y mortalidad materna en el mundo. Revisamos la evaluación y el manejo actualizado de las causas obstétricas de la hemorragia posparto (HPP), así como el diagnóstico y manejo de condiciones hematológicas que pueden causar o agravar la HPP, por ejemplo: coagulación intravascular diseminada, enfermedad de von Willebrand, trombocitopenia autoinmune y las microangiopatías trombóticas. Revisamos el rol del síndrome antifosfolípido y las trombofilias hereditarias como factores predisponentes a pérdidas fetales recurrentes y la ETEV en el embarazo y las recomendaciones actuales para la prevención de ambas complicaciones. Asimismo, repasamos el abordaje diagnóstico y líneas de manejo de la ETEV. Un objetivo adicional fue enfatizar la importancia del trabajo colaborativo multidisciplinario para lograr el manejo exitoso de las gestantes con las complicaciones obstétricas y hematológicas descritas.

Bleeding and venous thromboembolism (VTE) are among the five most common causes of morbidity and mortality in pregnant women worldwide. This review describes the current evaluation and management of the obstetric causes of postpartum hemorrhage (PPH), as well as the diagnosis and management of hematologic conditions which can cause or worsen PPH, such as disseminated intravascular coagulation, von Willebrand disease, autoimmune thrombocytopenia and the thrombotic microangiopathies. It also describes the role of the antiphospholipid syndrome and inherited thrombophilia as predisposing factors for recurrent pregnancy loses and VTE, and the current recommendations for the prevention of both complications. As well, the current diagnostic approach and management of ETEV are described. An additional objective of this Review is to emphasize the importance of a collaborative multidisciplinary approach for the successful management of the obstetric and hematologic complications herein described.

Asociación del incremento del índice de masa corporal y la presencia de infección de las vías urinarias en primigestas

Introducción. La condición nutricional de la mujer antes y durante el embarazo es uno de los determinantes del riesgo de morbimortalidad materna. Objetivo. Determinar la relación del incremento del índice de masa corporal y la presencia de infección de las vías urinarias en primigestas. Métodos. Estudio de casos y controles en expedientes de primigestas. Se estudiaron variables sociodemográficas (edad, escolaridad, vida en pareja y ocupación), condiciones obstétricas (riesgo obstétrico, semanas de inicio del control prenatal, semanas de resolución del embarazo y número de consultas prenatales), antropometría al inicio y al final del embarazo (peso, talla, índice de masa corporal y condición nutricional -peso bajo, peso normal, sobrepeso y obesidad-, ganancia de peso y ganancia de índice de masa corporal) y modificación de la condición nutricional al inicio y al final del embarazo. El análisis estadístico se efectuó con porcentajes, promedios, intervalos de confianza para promedios, prueba de chi2, razón de momios, intervalos de confianza para razón de momios, regresión lineal simple y proyección de la ocurrencia del evento. Resultados. Cuando el incremento del índice de masa corporal fue de 5 kg/m2, el promedio de infección de las vías urinarias correspondió a 1,62 y, si el incremento del índice de masa corporal fue 10 kg/m2, el promedio de infección de las vías urinarias fue 2,3. Conclusión. En nuestro estudio, a mayor incremento del índice de masa corporal durante el embarazo de la primigesta, mayor fue su probabilidad de presentar infección de las vías urinarias.

Introduction: The nutritional status of women before and during pregnancy is one of the determinants of the risk of maternal morbidity and mortality. Objective: To determine the relationship between the increase in body mass index and the presence of urinary tract infection in primigravidae. Methods: Case-control study in primigravidae records. We studied sociodemographic variables (age, schooling, life as a couple and occupation), obstetric conditions (obstetric risk, weeks of beginning of prenatal control, weeks of pregnancy resolution and number of prenatal visits), anthropometry at the beginning and end of pregnancy (weight, height, body mass index and nutritional condition -underweight, normal weight, overweight and obesity-, weight gain and body mass index gain), and modification of nutritional condition at the beginning and end of pregnancy. Statistical analysis was performed with percentages, averages, confidence intervals for averages, Chi2 test, odds ratio, confidence intervals for odds ratio, simple linear regression, and projection of event occurrence. Results: When the increase in body mass index was 5 kg/m2, the mean urinary tract infection corresponded to 1.62 and, if the increase in body mass index was 10 kg/m2, the mean urinary tract infection was 2.3. Conclusion: In our study, the greater the increase in body mass index during pregnancy of the primigravida, the greater her probability of presenting urinary tract infection.

En pacientes no vacunados la incidencia de hospitalización fue 62,2%, en pacientes con vacuna adenovirus modificado genéticamente la hospitalización fue 23,1% (p<0.001), riesgo relativo de 0,37 (IC 95%; 0,22-0,61); y en pacientes con vacuna de ácido ribonucleico mensajero la incidencia de hospitalización fue 1,7% (p<0.001), riesgo relativo de 0,03 (IC 95%; 0,006-0,10). Conclusiones: La vacuna anti COVID-19 en el ámbito poblacional es efectiva para evitar hospitalización en pacientes que presentan cuadro agudo de COVID-19 en la cuarta ola.

Objective: To assess the protective effect of the vaccine against SARS-CoV-2 upon hospitalizations due to COVID-19 during the fourth epidemic wave in Queretaro, Mexico. Methods: This investigation was designed as a retrospective cohort study in patients with COVID-19 during the fourth wave of the epidemic (December 19th, 2021, to January 9th, 2022). The exposed group consisted in those subjects who had received a vaccine against COVID-19 (genetically modified adenovirus vaccine and messenger ribonucleic acid vaccine); and the non-exposed group consisted in those people who were not vaccinated. Diagnosis of COVID-19 was made with a rapid antigenic test in oropharyngeal exudate, and the test was performed between the first and fifth day after the onset of symptoms. All patients who came to healthcare facilities because of symptoms, with a positive test and having received two doses of the vaccine. Statistical analysis included chi-square, relative risk, and confidence intervals (CI) for the relative risk. Results: Fifty-two patients who received a genetically modified vaccine, 119 who received a messenger ribonucleic acid vaccine, and 336 non vaccinated subjects were included in the study. The frequency of hospitalization was 62,2% in non-vaccinated persons, this rate was 23,1% (p<0.001), and relative risk was 0,37 (95% CI; 0,22-0,61) in those who received a genetically modified adenovirus vaccine, and it was 1.7% (p<0.001), and relative risk was 0,03 (95% CI; 0,006-0,10) in those who received the messenger ribonucleic acid vaccine. Conclusions: From a population point of view, the vaccine against COVID-19 was effective for preventing hospitalization in patients with acute COVID-19 disease during the fourth epidemic wave.
