[Gallbladder metastasis of clear cell renal carcinoma]. / Metástasis de carcinoma renal de células claras en la vesícula biliar.

Clear cell renal cell carcinoma (ccRCC) is an uncommon malignant neoplasm that accounts for 3% of all malignant tumors in adults. This tumor exhibits a high tendency to develop synchronous or metachronous metastases in different anatomical sites. Although gallbladder metastasis from ccRCC is extremely rare, sporadic cases have been reported in the medical literature. We present the case of a 78-year-old woman with a history of undifferentiated nasopharyngeal carcinoma, basal cell carcinoma, and ccRCC in the right kidney. She underwent radical nephrectomy. Histopathological analysis confirmed the diagnosis of ccRCC without vascular or ureteral invasion. Two years later, during follow-up, a nodular lesion was detected in the gallbladder through computed tomography. Despite the absence of symptoms, surgical resection was decided. Laparoscopic cholecystectomy was performed without complications. Histopathological examination confirmed the presence of ccRCC metastasis in the gallbladder. The patient had a favorable outcome and is currently under follow-up without recurrence. Gallbladder metastasis from ccRCC is extremely rare, but surgeons should consider this possibility in patients with a history of ccRCC. Preoperative differential diagnosis between primary gallbladder carcinoma and ccRCC metastasis can be challenging and is often confirmed through histopathological examination. Complete surgical resection is the best treatment option to achieve disease-free survival.

El carcinoma renal de células claras (CRCC) es una neoplasia maligna poco común que representa el 3% de todos los tumores malignos en adultos. Este tumor presenta una alta tendencia a desarrollar metástasis sincrónicas o metacrónicas en diferentes sitios anatómicos. Aunque la metástasis en la vesícula biliar por CRCC es extremadamente rara, se han reportado casos esporádicos en la literatura médica. Presentamos el caso de una mujer de 78 años con antecedentes de carcinoma indiferenciado de cavum, carcinoma basocelular y CRCC en riñón derecho. Se sometió a nefrectomía radical. El análisis histopatológico confirmó el diagnóstico de CRCC sin invasión vascular ni ureteral. Dos años después, durante el seguimiento, se detectó una lesión nodular en la vesícula biliar mediante tomografía computarizada. A pesar de la ausencia de síntomas, se decidió la resección quirúrgica. Se realizó colecistectomía laparoscópica sin complicaciones. El examen histopatológico confirmó la presencia de metástasis de CRCC en la vesícula biliar. La paciente evolucionó favorablemente encontrándose en seguimiento sin recurrencia. La metástasis vesicular por CRCC es extremadamente rara, pero los cirujanos deben considerarla en pacientes con antecedentes de CRCC. El diagnóstico diferencial prequirúrgico entre el carcinoma primario de vesícula biliar y la metástasis de CRCC puede ser desafiante y, a menudo, se confirma mediante el examen histopatológico. La resección quirúrgica completa parece ser la mejor opción de tratamiento para lograr una supervivencia libre de enfermedad.

Association between Vaccination Status for COVID-19 and the Risk of Severe Symptoms during the Endemic Phase of the Disease.

The global health emergency caused by COVID-19 concluded in May 2023, marking the beginning of an endemic phase. This study aimed to evaluate the association between vaccination status and other patient characteristics and the risk of severe disease during this new endemic period. A nationwide cohort study was conducted in Mexico, where we analyzed data from 646 adults who had received positive confirmation of COVID-19 through PCR testing from May to August 2023. The overall risk of severe symptoms in the study sample was 5.3%. The average time elapsed from the last vaccine shot to symptom onset was over six months in all the immunized groups (1, 2 or 3 vaccine doses). Compared to unvaccinated patients, those with three vaccine doses showed an elevated risk of severe symptoms. Advancing age and various chronic comorbidities (specifically cardiovascular, kidney, and obstructive pulmonary conditions) were associated with a heightened risk of severe COVID-19 manifestations. These findings underscore the ongoing seriousness of COVID-19, even in an endemic phase, underscoring the urgent need for tailored interventions aimed at high-risk patients.

Survival Analysis and Contributing Factors among PCR-Confirmed Adult Inpatients during the Endemic Phase of COVID-19.

In May 2023, the global health emergency status of COVID-19 concluded, marking the onset of an endemic era. This study assessed survival rates among PCR-confirmed adult inpatients during this phase and determined contributing factors. Employing a survival analysis approach, this investigation utilized a nationwide Mexican cohort encompassing 152 adult inpatients. Survival rates were computed using the Kaplan-Meier method, and a proportional Cox model identified mortality risk factors. Survival rates remained above 65% on day 14 after admission. Vaccination status, including the number of doses administered, was not significantly associated with fatal outcomes. Chronic kidney disease or a history of immunosuppression (due to any cause) increased mortality risk. Our findings underscore the persistent severity of COVID-19 beyond the global health emergency, emphasizing the necessity for tailored interventions for vulnerable patients.

Effectiveness of Nitrate Intake on Recovery from Exercise-Related Fatigue: A Systematic Review.

BACKGROUND: Recovery between efforts is critical to achieving optimal physical and sports performance. In this sense, many nutritional supplements that have been proven to improve recovery and physical and physiological performance are widely used. Supplements such as nitrates (NO3-), including organic foods such as beets, promote muscle recovery and relieve fatigue. This study aimed to comprehensively summarise the available literature on the effect of NO3- consumption on exercise-related fatigue and muscle damage. METHODS: A systematic search was carried out based on the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) using electronic databases (e.g., PubMed, Scopus, and Web of Science). From a total of 1634 studies identified, 15 studies were included in this review. RESULTS: Based on the review, NO3- intake provokes physiological and metabolic responses that could potentially boost exercise-related recovery. NO3- could improve recovery indicators related to strength, pain, inflammation, and muscle damage. CONCLUSIONS: Despite the relative proven effectiveness of NO3- on recovery after aerobic and anaerobic efforts, based on the heterogeneity of the procedures (e.g., dosage, chronic vs. acute intake, participants' characteristics, variables and outcomes), it could be premature to suggest its extended use in sports.

Inteligencia emocional en residentes de Cirugía General: análisis de una encuesta nacional / Emotional intelligence among residents in general surgery: analysis of a national survey

RESUMEN Antecedentes: la inteligencia emocional (IE) es la capacidad de reconocer nuestros propios sentimientos y los de los demás, de motivarnos y de manejar adecuadamente las relaciones interpersonales. La IE se ha relacionado con muchas competencias no técnicas necesarias entre los médicos en formación. Objetivo: describir las características psicométricas de la IE en médicos residentes de Cirugía General de la Argentina y analizar los efectos que ejercen sobre ella la edad, el sexo, el ámbito de desempeño y el año de residencia. Material y métodos: estudio prospectivo, analítico de corte transversal; se utilizó la encuesta anónima y autogestionada Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF v1.5) respondida en línea durante el mes de marzo de 2020. Se aplicó la prueba de Kolmogorov-Smirnov para variables cuantitativas, pruebas T y la prueba ANOVA (IC 95%, p estadística α 0,05). Resultados: fueron respondidas 156 encuestas, de las cuales 105 (67,3%) corresponden a mujeres y 51 (32,7%) a hombres. Edad promedio: 29,02 ± 3,69 años. El promedio global de la prueba fue de 4,58 ± 0,89. El análisis ANOVA demostró que existen diferencias estadísticamente significativas de la dimensión bienestar entre los diferentes años de residencia (p = 0,002) así como en puntajes globales de IE (p = 0,0001). Conclusión: la IE es un modelo atractivo y eficaz para definir y capacitar a los futuros cirujanos generales en competencias no técnicas. Estos hallazgos son importantes para generar nuevas propuestas de formación.

ABSTRACT Background: Emotional intelligence (EI) is the ability to recognize our own feelings and those of others, to motivate us and properly manage relationships. EI encompasses many non-technical skills that are important for physicians in training. Objective: The aim of this study was to describe the psychometric characteristics of EI among residents in general surgery in Argentina and to analyze the effects of age, sex, scope of practice and postgraduate year level on it. Material and methods: We conducted a prospective, cross-sectional analytic study using the Trait Emotional Intelligence Questionnaire Short Form (TEIQue-SF v1.5), a self-report and anonymous survey that was answered on-line during March 2020. The statistical analysis was performed by using the Kolmogorov-Smirnov test for quantitative variables, Student's t-test and ANOVA (95% CI, p statistic α 0.05). Results: The survey was responded by 156 physicians; 105 (67.3%) were women and 51 (32.7%) were men (mean age: 29.02 ± 3.69 years). Mean global score was 4.58 ± 0.89. ANOVA showed statistically significant differences in the well-being dimension and global scores of EI across the different postgraduate year levels (p = 0.002 and p = 0.0001, respectively). Conclusion: EI is an attractive and effective model for defining and training future general surgeons in non-technical skills. These findings are important for generating new proposals for training.

Alterations in blink and masseter reflex latencies in older adults with neurocognitive disorder and/or diabetes mellitus.

BACKGROUND: Blink and masseter reflexes provide reliable, quantifiable data on the function of the central nervous system: Delayed latencies have been found in patients with neurocognitive disorder (ND) and type 2 diabetes mellitus (T2DM), but this has not been studied in patients with both pathologies. AIM: To investigate if older adults with ND plus T2DM have prolonged latencies of blink and masseter-reflex and if they were associated with disease progression. METHODS: This cross-sectional study included 227 older adults (> 60 years) from Colima, Mexico. Neurocognitive disorder was identified by a neuropsychological battery test, and T2DM identified by medical history, fasting glucose, and glycosylated hemoglobin. Latencies in the early reflex (R1), ipsilateral late (R2), and contralateral late (R2c) components of the blink reflex were analyzed for all subjects, and 183 subjects were analyzed for latency of the masseter reflex. RESULTS: In 20.7% of participants, ND was detected. In 37%, T2DM was detected. Latencies in R1, R2, and R2c were significantly prolonged for groups with ND plus T2DM, ND, and T2DM, compared with the control group (P < 0.0001). The masseter reflex was only prolonged in older adults (regardless of T2DM status) with ND vs controls (P = 0.030). In older adults with ND and without T2DM, the more the cognitive impairment progressed, the more prolonged latencies in R2 and R2c presented (P < 0.01). CONCLUSION: These findings suggest that blink and masseter reflexes could be used to evaluate possible changes in brainstem circuits in older adults with ND and T2DM.

Background: Acute appendicitis (AA) is the most common surgical emergency worldwide. Its correct and early diagnosis is essential to avoid unnecessary surgeries and complications associated with its natural history. Objective: The aim of this study was to determine the diagnostic sensitivity and specificity of the RIPASA score in patients with suspected AA. Material and methods: This analytical, cross-sectional, observational and retrospective study included appendectomy specimens of patients of both sexes > 18 years operated on with clinical diagnosis of AA between January 1 and December 31, 2017. The histopathological examination of the appendectomy specimens was considered the gold standard diagnostic test. A score of 7.5 for the RIPASA score was chosen as cut-off value. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results: A total of 68 appendectomies were included; 57 (83.82%) specimens were positive for acute appendicitis. Mean age was 43.32 years. The histological diagnosis of AA was present in 32 (84.21%) men and in 25 (83.33%) women. For the RIPASA score, 54 patients had a true positive result (cut-off point ≥ 7.5 and positive histology for AA) with a sensitivity of 93%, specificity of 40%, PPV of 90%, NPV of 50%, positive likelihood ratio of 1.55 and negative likelihood ratio of 0.175. Conclusion: The RIPASA score has demonstrated excellent sensitivity and specificity for the clinical diagnosis of AA in a fast, simple and non-invasive fashion.

[Splenic cystic lymphagioma]. / Linfagioma quistico del bazo.

Splenic cystic lymphangioma is a very rare benign neoplasia characterized by cystic dilation of the lymphatic vessels of the splenic parenchyima. It may occur in the spleen only or in multiple organs. We describe the case of a 46 year-old female, with he diagnosis of splenic cystic lymphangioma. Its clinical manifestations include abdominal pain, especially in left upper quadrant pain, abdominal distension, loss of appetite. Physical examination showed no specific findings. Ultrasonography and CT scann imaging showed multiple cysts replacing the normal parenchyma of the spleen. We report herein the surgical significance of lymphangioma of the spleen from both diagnostic and also therapeutic aspects, and we discuss laparoscopic splenectomy as an effective procedure for an excision of a splenic tumor suspected to be benign. .Histologic study after splenectomy confirmed the diagnosis of cystic lymphangioma of the spleen.
