Cistoadenoma mucinoso gigante de ovario / Giant ovarian mucinous cystadenoma

Aunque el cistoadenoma mucinoso de ovario tiene un crecimiento benigno, puede crecer hasta tener grandes dimensiones. Se presenta el caso de una paciente de 70 años que acudió a consulta por presentar dolor abdominal recurrente y difuso. A la exploración física se palpó una gran masa que ocupaba toda la cavidad abdominal, hasta la apófisis xifoides, redondeada, renitente, de bordes definidos, no dolorosa, no movible. Presencia de edema en miembros inferiores. Durante el acto operatorio se identificó útero miomatoso y quiste gigante de ovario izquierdo, aproximadamente de 40 x 30 cm y 13,6 kg de peso. Se realizó histerectomía total abdominal y salpingooforectomía bilateral. La biopsia confirmó el diagnóstico de cistoadenoma mucinoso benigno de ovario y leiomiomatosis uterina. El posoperatorio transcurrió favorablemente. La incidencia de cistoadenoma gigante de ovario es desconocida, debido a la falta de un concepto estandarizado y las modalidades de imagen avanzadas disponibles en la actualidad(AU)

Although ovarian mucinous cystadenoma has a benign growth, it can grow to be very large. We present the case of a 70-year-old patient who came to the clinic for recurrent and diffuse abdominal pain. On physical examination, a large mass was palpated that occupied the entire abdominal cavity, up to the xiphoid appendix, rounded, retentive, with defined edges, non- painful, non-movable. Presence of edema in lower limbs. During the surgical act, a myomatous uterus and a giant left ovarian cyst measuring approximately 40 x3 0 cm and weighing 13.6 kg were identified. Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. The biopsy confirmed the diagnosis of benign ovarian mucinous cystadenoma and uterine leiomyomatosis. The postoperative period progressed favorably. The incidence of giant ovarian cystadenoma is relatively unknown due to the lack of a standardized concept and currently available advanced imaging modalities(AU)

Passive leg raising test using the carotid flow velocity-time integral to predict fluid responsiveness.

PURPOSE: The passive leg raising test (PLR) is a noninvasive method widely adopted to assess fluid responsiveness. We propose to explore if changes in the carotid flow assessed by echo-Doppler can predict fluid responsiveness after a PLR. METHODS: We conducted a performance diagnostic study in two intensive care units from Argentina between February and April 2022. We included patients with signs of tissular hypoperfusion that required fluid resuscitation. We labeled the patients as fluid responders when we measured, after a fluid bolus, an increase greater than 15% in the left ventricle outflow tract (LVOT) VTI in an apical 5-chamber view and we compared those results with the carotid flow (CF) velocity-time integral (VTI) from the left supraclavicular region in a semi-recumbent position and during the PLR. RESULTS: Of the 62 eligible patients, 50 patients (80.6%) were included. The area under the ROC curve for a change in CF VTI during the PLR test was 0.869 (95% CI 0.743-0.947). An increase of at least of 11% in the CF VTI with the PLR predicted fluid-responsiveness with a sensitivity of 77.3% (95% CI 54.6-92.2%) and specificity of 78.6% (95% CI 59-91.7%). The positive predictive value was 73.9% (95% CI 57.4-85.6%) and the negative predictive value was 81.5% (95% CI 66.5-90.7%). The positive likelihood ratio was 3.61 and the negative likelihood ratio was 0.29. CONCLUSION: An increase greater than 11% in CF VTI after a PLR may be useful to predict fluid responsiveness among critically ill patients.

Assessment of interleukin-10 promoter variant (-1082A/G) and cytokine production in patients with hemolytic uremic syndrome.

Introduction: Hemolytic uremic syndrome (HUS) is a condition that results in acute kidney failure mainly in children, which is caused by Shiga toxin-producing Escherichia coli and inflammatory response. Although anti-inflammatory mechanisms are triggered, studies on the implication in HUS are scarce. Interleukin-10 (IL-10) regulates inflammation in vivo, and the interindividual differences in its expression are related to genetic variants. Notably, the single nucleotide polymorphism (SNP) rs1800896 -1082 (A/G), located in the IL-10 promoter, regulates cytokine expression. Methods: Plasma and peripheral blood mononuclear cells (PBMC) were collected from healthy children and HUS patients exhibiting hemolytic anemia, thrombocytopenia, and kidney damage. Monocytes identified as CD14+ cells were analyzed within PBMC by flow cytometry. IL-10 levels were quantified by ELISA, and SNP -1082 (A/G) was analyzed by allele-specific PCR. Results: Circulating IL-10 levels were increased in HUS patients, but PBMC from these patients exhibited a lower capacity to secrete this cytokine compared with those from healthy children. Interestingly, there was a negative association between the circulating levels of IL-10 and inflammatory cytokine IL-8. We observed that circulating IL-10 levels were threefold higher in HUS patients with -1082G allele in comparison to AA genotype. Moreover, there was relative enrichment of GG/AG genotypes in HUS patients with severe kidney failure. Discussion: Our results suggest a possible contribution of SNP -1082 (A/G) to the severity of kidney failure in HUS patients that should be further evaluated in a larger cohort.

Nasal immunization with H7 flagellin protects mice against hemolytic uremic syndrome secondary to Escherichia coli O157:H7 gastrointestinal infection.

Introduction: Shiga-toxin (Stx) producing Escherichia coli (STEC) O157:H7 is the most frequent serotype associated with hemolytic uremic syndrome (HUS) after gastrointestinal infections. Protection against HUS secondary to STEC infections has been experimentally assayed through the generation of different vaccine formulations. With focus on patients, the strategies have been mainly oriented to inhibit production of Stx or its neutralization. However, few approaches have been intended to block gastrointestinal phase of this disease, which is considered the first step in the pathogenic cascade of HUS. The aim of this work was to assay H7 flagellin as a mucosal vaccine candidate to prevent the systemic complications secondary to E. coli O157:H7 infections. Materials and methods: The cellular and humoral immune response after H7 nasal immunization in mice were studied by the analysis of systemic and intestinal specific antibody production, as well as cytokine production and lymphocyte proliferation against H7 flagellin ex vivo. Results: Immunized mice developed a strong and specific anti-H7 IgG and IgA response, at systemic and mucosal level, as well as a cellular Th1/Th2/Th17 response. H7 induced activation of bone marrow derived dendritic cells in vitro and a significant delayed-type hypersensitivity (DTH) response in immunized mice. Most relevant, immunized mice were completely protected against the challenge with an E. coli O157:H7 virulent strain in vivo, and surviving mice presented high titres of anti-H7 and Stx antibodies. Discussion: These results suggest that immunization avoids HUS outcome and allows to elicit a specific immune response against other virulence factors.

Transesophageal Echocardiographic Assessment in Patients with Severe Respiratory Distress due to COVID-19 in the Prone Position: A Feasibility Study.

Background and aim: Our aim was to assess the feasibility, safety, and utility of implementing transesophageal echocardiographic screening in patients with coronavirus disease-2019 (COVID-19)-related acute respiratory distress syndrome (ARDS), receiving mechanical ventilation (MV) and in prone position (PP). Methods: Prospective observational study performed in an intensive care unit; patients 18 years, with ARDS, invasive MV, in PP were included. A total of 87 patients were included. Results: There was no need to change ventilator settings, hemodynamic support, or any difficulties with the insertion of the ultrasonographic probe. Mean duration of transesophageal echocardiography (TEE) was 20 minutes. No displacement of the orotracheal tube, vomiting, or gastrointestinal bleeding was observed. Frequent complication was displacement of the nasogastric tube in 41 (47%) patients. Severe right ventricular (RV) dysfunction was detected in 21 (24%) patients and acute cor pulmonale was diagnosed in 36 (41%) patients. Conclusion: Our results show the importance of assessing RV function during the course of severe respiratory distress and the value of TEE for hemodynamic assessment in PP.

Caracterización de las fístulas enterocutáneas posoperatorias / Characterization of Postoperative Enterocutaneous Fistulas

Introducción: Las fístulas enterocutáneas representan una enfermedad grave que deben afrontar un gran número de cirujanos durante el ejercicio de la profesión. El tratamiento suele ser extremadamente complejo y siempre requiere de una intervención multidisciplinaria adaptada para cada caso en particular. Objetivo: Evaluar las características clínico-epidemiológicas y terapéuticas de las fístulas enterocutáneas posoperatorias. Métodos: Se realizó un estudio observacional, descriptivo, con recogida prospectiva de datos en el quinquenio 2013-2017. El universo fue de 28 pacientes diagnosticados con fístula enterocutánea posoperatoria y se usaron las variables: edad, sexo, carácter de la intervención, diagnóstico operatorio, tipo de fístula, tratamiento definitivo, complicaciones y pilares de tratamiento. Resultados: La edad media fue de 49 años. Las fístulas fueron más frecuentes en el sexo femenino (53,57 por ciento). El 78,57 por ciento de los pacientes fueron intervenidos con carácter de urgencia, y el 25 por ciento tuvieron un diagnóstico operatorio de oclusión intestinal mecánica por bridas seguida de la oclusión intestinal por tumor de colon izquierdo (17,86 por ciento). La hemicolectomía izquierda con anastomosis término-terminal (21,43 por ciento) y la resección intestinal con anastomosis término-terminal (17,86 por ciento) fueron los principales procedimientos quirúrgicos realizados. Conclusiones: Las fístulas de tipo II y de bajo gasto prevalecieron en la serie de casos en una media de tiempo que se corresponde con lo reportado en la literatura. La infección del sitio quirúrgico fue la complicación más observada y los pilares del tratamiento fueron cumplidos en la mayoría de los pacientes prevaleciendo el cierre espontáneo como tratamiento definitivo(AU)

Introduction: Enterocutaneous fistulas are a serious disease that a large number of surgeons must face during the practice of their profession. Their treatment is usually extremely complex and always requires a multidisciplinary intervention adapted to each particular case. Objective: To evaluate the clinical-epidemiological and therapeutic characteristics of postoperative enterocutaneous fistulas. Methods: An observational and descriptive study was performed, with prospective data collection, in the five-year period 2013-2017. The study universe was 28 patients diagnosed with postoperative enterocutaneous fistula. The following variables were used: age, sex, nature of the intervention, operative diagnosis, type of fistula, definitive treatment, complications and treatment cornerstones. Results: The mean age was 49 years. Fistulas were more frequent in the female sex (53.57 percent). 78.57 percent of the patients underwent emergency surgery, while 25 percent had an operative diagnosis of mechanical intestinal occlusion due to adherences, followed by intestinal occlusion due to left colon tumor (17.86 percent). Left hemicolectomy with end-to-end anastomosis (21.43 percent) and intestinal resection with end-to-end anastomosis (17.86 percent) were the main surgical procedures. Conclusions: Type II and low-output fistulas prevailed in the case series at a mean time that corresponds to that reported in the literature. Surgical site infection was the most frequently observed complication, while the treatment cornerstones were fulfilled in most patients, with spontaneous closure prevailing as a definitive treatment(AU)

Carotid flow as a surrogate of the left ventricular stroke volume.

Transthoracic echocardiography (TTE) is a fundamental tool for hemodynamic monitoring in critical patients. It allows evaluating the left ventricle's stroke volume based on the measurement of the velocity-time integral (VTI) of the left ventricle outflow tract (LVOT). However, in the intensive care unit obtaining adequate echocardiographic views may present a challenge. We propose to measure, as a surrogate of the stroke volume, the carotid flow with a novel technique. This is an observational, prospective, and simple blind study, conducted in the intensive care unit of Sanatorio de los Arcos and Hospital Aleman, in Buenos Aires, Argentina. We measured the carotid systodiastolic flow (CSD) VTI and the carotid systolic flow (CS) VTI at the level of the left supraclavicular fossa and we compared it with the LVOT VTI obtained by TTE. We evaluated 43 subjects. Spearman's correlation coefficient between LVOT VTI and CS VTI was 0.81 (95% CI 0.67-0.89) and between LVOT VTI and CSD VTI was 0.89 (95% CI 0.81-0.94). The Bland-Altman method analysis of the 5-chamber apical window LVOT VTI compared to the CSD VTI showed a bias of - 0.2 (95% CI - 0.82 to 0.43), with a concordance interval between - 4.2 (95% CI - 5.2 to - 3.1) and 3.8 cm (95% CI 2.7 to 4.9). The percentage error was 37.9%. Almost 100% of the values fell within the concordance limits, and no trend was observed in bias across the spectrum of mean variables. Although the CSD VTI could not be interchangeable with the LVOT VTI, it could be considered as its surrogate.

Síndrome de burnout en cirujanos generales en tiempos de la pandemia COVID-19

Objetivo: Evaluar el síndrome de burnout (SB) en cirujanos generales. Material y Método: Se realizó un estudio de corte transversal en nuestro centro hospitalario, en agosto de 2021. La muestra estuvo formada por 56 profesionales de la salud que incluyeron a residentes y especialistas en cirugia general quienes prestaron servicio en el contexto de la COVID-19. Resultados: La prevalencia del burnout fue del 71%, la edad media fue de 34 años y los residentes fueron los más afectados (62,5%). La distribución por sexo fue de 82,5% en masculinos y 17,5% en el sexo femenino. Del total de evaluados, 23 son casados y 17 solteros, predominando los cirujanos con hijos (60%). Discusión: Entre los pocos estudios publicados sobre el SB en trabajadores de la salud en tiempos de COVID-19 se ubican como posibles factores predisponentes: a las privaciones de sueño, el riesgo biológico ocupacional intrínseco, la cuarentena obligada a la que tienen que someterse los trabajadores de la salud fuera de casa y los dilemas éticos en la toma de decisiones de atención a pacientes. Sin embargo, un estudio ha mostrado que los estresores vinculados al SB más importantes son la falta de equipo de protección personal, el miedo al contagio de COVID-19 y el miedo de contagiar a los familiares. Conclusión: Existe una alta prevalencia del SB en cirujanos generales en el contexto de la pandemia COVID-19. Los más afectados fueron residentes jóvenes de sexo masculino, casados, con hijos y con bajos ingresos económicos.

Objective: To evaluate the burnout syndrome (BS) in general surgeons. Material and Method: A cross-sectional study was carried out in our hospital in August 2021. The sample consisted of 56 health professionals that included residents and specialists in general surgery who provided service in the context of COVID-19 Results: The prevalence of burnout was 71%, the mean age was 34 years and the residents were the most affected (62.5%). Sex was 82.5% in males and 17.5% in females. Of the total evaluated, 23 are married and 17 are single, with a predominance of surgeons with children (60%). Discussion: Among the few studies published on BS in health workers in times of COVID-19, the following are located as possible predisposing factors: sleep deprivation, intrinsic occupational biological risk, the forced quarantine that patients have to undergo. out-of-home health workers and ethical dilemmas in patient care decision-making. However, a study has shown that the most important stressors linked to BS are the lack of personal protective equipment, the fear of contagion of COVID-19 and the fear of infecting family members. Conclusion: There is a high prevalence of BS in general surgeons in the context of the COVID-19 pandemic. The most affected were young male residents, married, with children and with low income.

Eficacia de la impronta citológica peritoneal para decidir cuándo detener los lavados peritoneales programados / Efficacy of Peritoneal Cytological Imprinting in Deciding When to Stop Scheduled Peritoneal Lavages

Introducción: La no existencia de un parámetro preestablecido que permita determinar el momento preciso para suspender los lavados peritoneales programados, conlleva a que muchas veces se realice un número insuficiente de ellos, o tal vez estos se prolonguen de forma innecesaria y aumentan las probabilidades de fallecimiento del paciente. Objetivo: Determinar la eficacia de la impronta citológica peritoneal para decidir cuándo detener los lavados peritoneales programados. Métodos: Se realizó un estudio descriptivo de exactitud diagnóstica, en una serie de casos, con recogida prospectiva de datos desde enero de 2010 hasta diciembre de 2014, en el Hospital Provincial Clínico-Quirúrgico Docente "Celia Sánchez Manduley. La muestra quedó conformada por 42 pacientes que fueron tratados por peritonitis secundaria persistente. Se clasificaron según cuatro categorías de correlación y se tomó como estándar de referencia a la biopsia por parafina. Resultados: Las muestras con inflamación aguda peritoneal y curación de la inflamación peritoneal se identificaron correctamente en 39/42 casos, por lo tanto, el porcentaje predictivo global de la impronta citológica fue del 92,86 por ciento. La sensibilidad en el diagnóstico de inflamación aguda peritoneal fue del 100 por ciento, la especificidad del 92,68 por ciento, el valor predictivo positivo fue del 24,99 por ciento y el valor predictivo negativo del 100 por ciento. Las razones de verosimilitudes positiva y negativa fueron 13,67 y 0, respectivamente. El coeficiente (κ) fue de 0,376. Conclusiones: La impronta citológica peritoneal constituye un método diagnóstico eficaz para descartar inflamación aguda peritoneal cuando el resultado es negativo y se consideró de gran utilidad para detener los lavados peritoneales programados(AU)

Introduction: The lack of a pre-established parameter that allows determining the precise moment to suspend the scheduled peritoneal lavages, often leads to performing insufficient number of them, or perhaps these are unnecessarily prolonged, increasing the probability of the patient´s death. Objective: To determine the efficacy of peritoneal cytological imprinting in deciding when to stop scheduled peritoneal lavages. Methods: A descriptive study of diagnostic accuracy was carried out, in a series of cases, with prospective data collection in the five-year period from 2010 to 2014 at Celia Sánchez Manduley Provincial Clinical-Surgical Teaching Hospital. The sample was made up of 42 patients who were treated for persistent secondary peritonitis. They were classified according to four correlation categories, taking paraffin biopsy as reference standard. Results: Samples with acute peritoneal inflammation and healing of peritoneal inflammation were correctly identified in 39/42 cases. Therefore, the global predictive percentage of the cytological imprint was 92.86 percent. The sensitivity in the diagnosis of acute peritoneal inflammation was 100 percent, the specificity was 92.68 percent, the positive predictive value was 24.99 percent, and the negative predictive value was 100 percent. The positive and negative likelihood ratios were 13.67 and 0, respectively. Cohen's kappa coefficient (κ) was 0.376. Conclusions: The peritoneal cytological imprint is an effective diagnostic method to rule out acute peritoneal inflammation when the result is negative and it was considered very useful to stop scheduled peritoneal lavages(AU)

Ser e estar em refúgio: o processo grupal em uma intervenção de cuidado de equipe / Being and staying at a shelter: the group process in a work team support intervention / Ser y estar en refugio: el proceso grupal en una intervención de cuidado de equipo

O trabalho é uma reflexão crítica sobre uma intervenção realizada no Centro Nocturno (Albergue) do Programa de Atención a Personas en Situación de Calle (PASC), do Ministerio de Desarrollo Social (MIDES, Uruguai) que visa à reinserção sociocultural/laboral dos usuários. Trabalhou-se com a equipe do albergue (coordenador, técnicos e educadores), a partir de uma demanda da Coordenação do Albergue ao Departamento de Fotolinguagem da Asociación de Psicopatología y Psiquiatría de la Infancia y la Adolescencia (APPIA). A metodologia combinou Fotolinguagem, Palavra e Psicodrama. O discurso dos participantes foi analisado salvaguardando a identidade dos participantes. Surgiram elementos que colocavam em risco a saúde ocupacional. Estes resultavam de uma tarefa altamente exigente, com insuficientes antecedentes e recursos disponíveis no sistema institucional. Trata-se de um trabalho pioneiro que exige a convivência com o erro em situações extremas. Foi observado um aumento da autoconfiança para desbravar um território desafiador. Foi valorizado o ato de fazer, de transcender e de criar saberes, assim como o conhecimento que surge da experiência para contribuir e trocar ideias com outras instituições e melhorar assim os programas de intervenção.

This work is a critical reflection on an intervention carried out at a night shelter of the Homeless Assistance Program (PASC), under the Ministry of Social Development (MIDES), aimed at the socio-cultural/labour reintegration of the users. The intervention was carried out with the work team (coordinator, technicians and educators) upon request of the Coordinator to the Photolanguage Department of the Uruguayan Association of Psychopathology and Psychiatry of Children and Adolescents (APPIA). The methodology articulated Photolanguage, words and Psychodrama. The discourse of the participants was analyzed without disclosing their identities. There were working conditions that jeopardized their occupational health; they involved a very demanding job combined with a lack of background and resources in the institutional system. It is a pioneering work that requires coping with error in extreme situations. Participants experienced an increase in their self-confidence which was necessary to open new pathways in a challenging territory. Participants placed value on hands-on experience, on going beyond what was already accomplished by creating new knowledge that can contribute to enhance the interaction with other professionals and institutions to improve future programs.

Lung ultrasound as a predictor of mortality of patients with COVID-19.

OBJECTIVE: To evaluate the performance of lung ultrasound to determine short-term outcomes of patients with COVID-19 admitted to the intensive care unit. METHODS: This is a Prospective, observational study. Between July and November 2020, 59 patients were included and underwent at least two LUS assessments using LUS score (range 0-42) on day of admission, day 5th, and 10th of admission. RESULTS: Age was 66.5±15 years, APACHE II was 8.3±3.9, 12 (20%) patients had malignancy, 46 (78%) patients had a non-invasive ventilation/high-flow nasal cannula and 38 (64%) patients required mechanical ventilation. The median stay in ICU was 12 days (IQR 8.5-20.5 days). ICU or hospital mortality was 54%. On admission, the LUS score was 20.8±6.1; on day 5th and day 10th of admission, scores were 27.6±5.5 and 29.4±5.3, respectively (P=0.007). As clinical condition deteriorated the LUS score increased, with a positive correlation of 0.52, P <0.001. Patients with worse LUS on day 5th versus better score had a mortality of 76% versus 33% (OR 6.29, 95%CI 2.01-19.65, p. 0.003); a similar difference was observed on day 10. LUS score of 5th day of admission had an area under the curve of 0.80, best cut-point of 27, sensitivity and specificity of 0.75 and 0.78 respectively. CONCLUSION: These findings position LUS as a simple and reproducible method to predict the course of COVID-19 patients.

Taponamiento cardíaco y miocarditis en paciente con infección aguda por SARS-CoV-2 / Cardiac tamponade and myocarditis in a patient with acute SARS-CoV-2 infection

Resumen Describimos una paciente con COVID-19, con derrame pericárdico, taponamiento cardíaco y depresión miocárdica grave. Mujer de 51 años, sin enfermedad previa, COVID-19 leve que presentó tres episodios de síncope en domicilio. El electrocardiograma mostró ritmo sinusal, ST de concavidad superior difuso 2 mv; en la tomografía se observó derrame pericárdico y parénquima pulmonar normal. Ingresó a terapia intensiva con shock y requerimiento de asistencia ventilatoria mecánica (AVM). En el ecocardiograma se obser vó derrame pericárdico y taponamiento; se realizó drenaje. El ecocardiograma transesofágico mostró deterioro moderado de función sistólica biventricular; strain longitudinal global -14.2%, Fey estimada: 43%; deformación global circunferencial: -10.1%. A los 7 días del ingreso, la tomografía reveló infiltrados bilaterales y engrosamiento pericárdico con realce post-contraste y derrame pericárdico leve. El día 12 posterior al ingreso, se suspendió el soporte inotrópico; y la paciente, hemodinámicamente estable, se desvinculó de la AVM.

Abstract We describe a patient with COVID-19, with pericardial effusion, cardiac tamponade and severe myocar dial depression. A 51-year-old woman, previously healthy, with mild COVID-19 presented with three episodes of syncope. She was admitted to the emergency room. An electrocardiogram showed sinus rhythm, diffuse superior concavity ST 2 mv; a CT scan showed pericardial effusion, without lung pathological findings. Due to shock, dyspnoea and encephalopathy, the patient was admitted to intensive care, where she received vasopressor support and mechanical ventilation. A bedside ultrasound showed pericardial effusion and tamponade; drainage was performed; transoesophageal ultrasound showed moderate deterioration of biventricular systolic function; global longitudinal strain -14.2%, estimated Fey 43%; global circumferential strain -10.1%. Seven days after admission, CT scan revealed bilateral infiltrates and pericardial thickening with post-contrast enhancement and mild pericardial effusion. On day 12 post admission, inotropic support was discontinued; patient on mechanical ventilation weaning and haemodynamically stable.

Alendronate inhibits triglyceride accumulation and oxidative stress in adipocytes and the inflammatory response of macrophages which are associated with adipose tissue dysfunction.

Alendronate, a bisphosphonate used to prevent osteoporosis, stimulates osteogenesis but impairs adipogenesis. Different clinical trials suggest that the incidence of diabetes may be lower in patients treated with alendronate. Taking into account the importance of adipocytes and macrophages of adipose tissue in insulin resistance and type 2 diabetes, it is necessary to evaluate the effect of alendronate in both cell types. In this paper, we investigated the effect of alendronate on the differentiation to adipocytes of 3T3-L1 fibroblasts, the cell line most used to study adipogenesis, and also its effect on lipid content and oxidative stress in mature adipocytes as well as on the inflammatory response of macrophages. We found that alendronate inhibits differentiation of 3T3-L1 fibroblasts to adipocytes in keeping with reports in other cell lines. On the other hand, treatment of 3T3-L1 adipocytes with alendronate was able to decrease triglyceride content and to prevent H2O2-induced lipid peroxidation which was evaluated as an indicator of oxidative stress. In addition, it was found that activation of RAW 264.7 macrophages to a pro-inflammatory M1 type is inhibited by this bisphosphonate. These results suggest that alendronate may contribute to prevent adipocyte excessive enlargement and the induction of oxidative stress in 3T3-L1 adipocytes as well as the activation of macrophages to a pro-inflammatory M1 type, which are events associated with adipose tissue dysfunction and insulin resistance. In this study, we unraveled the underlying mechanisms of events that were previously observed in clinical trials.

Escala predictiva de dehiscencia de la línea de sutura intestinal / A Predictive Scale for Dehiscence of the Intestinal Suture Line

Introducción: La dehiscencia de la línea de sutura es una de las complicaciones más frecuentes en la cirugía intestinal. Objetivo: Diseñar una escala predictiva para estimar de forma individual la probabilidad de dehiscencia de la línea de sutura intestinal. Métodos: Se realizó un estudio, analítico, de cohorte con recogida retrospectiva de datos en el sexenio 2014-2019 en el hospital "Celia Sánchez Manduley". La muestra fue de 437 pacientes y se usó la variable dependiente: dehiscencia de la línea de sutura intestinal y variables independientes: edad, sexo, comorbilidad, hemoglobina, hipoalbuminemia, neoplasia de colon, riesgo anestésico, entre otras. Resultados: En el análisis multivariado se obtuvo un modelo ajustado con las variables: edad mayor de 70 años (p = 0,002), hipoalbuminemia (p = 0,014), anastomosis enterocólica (p = 0,018), cirugía urgente (p = 0,001) e íleo paralítico prolongado (p < 0,001). La escala predictiva fue derivada del modelo estadístico ajustado y clasificado en 3 grupos de riesgo la probabilidad de dehiscencia de la línea de sutura intestinal: bajo (menor de 2 puntos), moderado (entre 3 y 5 puntos) y elevado (mayor de 6 puntos). Presentó una sensibilidad de 89,6 por ciento, especificidad de 89,1 por ciento, porciento predictivo global de 89,2 por ciento, valor predictivo positivo de 66,1 por ciento y valor predictivo negativo de 97,2 por ciento. Tuvo una excelente calibración y un elevado poder discriminativo. Conclusión: Se obtuvo una escala predictiva para estimar de forma individual la probabilidad de dehiscencia de la línea de sutura intestinal(AU)

ABSTRACT Introduction: The suture line dehiscence is one of the most frequent complications in intestinal surgery. Objective: To design a predictive scale for estimating individual probability of suture line dehiscence. Methods: An analytical cohort study, which involved retrospective data collection, was carried out, in the six-year period of 2014-2019, at Celia Sánchez Manduley Hospital. The sample consisted of 437 patients. Dehiscence of the intestinal suture line was used as a dependent variable, while age, sex, comorbidity, hemoglobin, hypoalbuminemia, colon neoplasia, anesthetic risk, among others, were used as independent variables. Results: Through multivariate analysis, an adjusted model was obtained, with the following results for the variables: age over 70 years (P=0.002), hypoalbuminemia (P=0.014), enterocolic anastomosis (P=0.018), urgent surgery (P=0.001), and ileus prolonged paralytic (P < 0.001). The predictive scale was derived from the adjusted statistical model and, based on the probability of dehiscence of the intestinal suture line, classified into three risk groups: low (less than two points), moderate (between 3-5 points) and high (more than six points). It presented a sensitivity of 89.6 percent, a specificity of 89.1 percent, a global predictive percentage of 89.2 percent, a positive predictive value of 66.1 percent, and a negative predictive value of 97.2 percent. It had an excellent calibration and a high discriminative power. Conclusion: A predictive scale was obtained for estimating the individual probability of dehiscence of the intestinal suture line(AU)

Mucocele apendicular simulando apendicitis aguda complicada / Appendicular mucocele simulating complicated acute appendicitis / Mucocele apendicular simulando apendicite aguda complicada

RESUMEN Introducción: el término «mucocele¼, una denominación no específica y descriptiva referida a una acumulación mucosa anormal dentro de la luz del apéndice, independientemente de la causa subyacente, es una afección clínica rara que con poca frecuencia se considera en el diagnóstico diferencial de las lesiones localizadas en el cuadrante inferior derecho del abdomen. Objetivo: presentar un paciente con diagnóstico preoperatorio de apendicitis aguda complicada que fue intervenido quirúrgicamente de urgencia y se le diagnosticó finalmente un mucocele apendicular. Presentación del caso: paciente masculino de 52 años que fue admitido en la Unidad de Cuidados Intensivos y Emergentes por presentar dolor en la región lumbar derecha que se irradió a fosa iliaca derecha. Se acompañó de náuseas, vómitos abundantes, fiebre de 38,5-390 C, sed, oliguria, astenia y anorexia. Discusión: a la exploración física presentó mucosas pálidas y ligeramente secas, pulso débil y taquicárdico, hipotensión arterial, abdomen ligeramente distendido, doloroso a la palpación profunda en fosa ilíaca derecha. Los estudios imagenológicos sugirieron una colección apendicular. Con la sospecha clínica de apendicitis aguda complicada y ante la duda diagnóstica se decidió realizar laparotomía exploradora de urgencia. Durante el transoperatorio se identificó un mucocele apendicular. La histología confirmó un mucocele apendicular sin evidencia de origen neoplásico. El paciente evolucionó satisfactoriamente y se le dio de alta al cuarto dia posoperatorio. Conclusiones: el mucocele apendicular es una afección clínica-quirúrgica que, a pesar de ser conocida, su incidencia es muy baja; siendo el diagnóstico preoperatorio difícil por la variedad en su presentación clínica.

ABSTRACT Introduction: the term «mucocele¼, a nonspecific and descriptive name referring to an abnormal mucous accumulation within the lumen of the appendix, regardless of the underlying cause, is a rare clinical condition that is infrequently considered in the differential diagnosis of the lesions located in the lower right quadrant of the abdomen. Objective: to present a patient with a preoperative diagnosis of complicated acute appendicitis who underwent emergency surgery and was finally diagnosed with an appendicular mucocele. Clinical case: 52-year-old male patient who was admitted to the Emergency and Intensive Care Unit for presenting pain in the right lumbar region that radiated to the right iliac fossa. He was accompanied by nausea, profuse vomiting, fever of 38.5-390 C, thirst, oliguria, asthenia, and anorexia. Discussion: on physical examination, she presented pale and slightly dry mucous membranes, weak and tachycardic pulse, arterial hypotension, slightly distended abdomen, painful on deep palpation in the right iliac fossa. Imaging studies suggested an appendicular collection. With the clinical suspicion of complicated acute appendicitis and the diagnostic doubt, it was decided to perform emergency exploratory laparotomy. During the intraoperative period, anappendicular mucocele was identified. Histology confirmed an appendicular mucocele with no evidence of neoplastic origin. The patient evolved satisfactorily and was discharged on the fourth postoperative day. Conclusions: the appendicular mucoceleis a clinical-surgical condition that, despite being known, its incidence is very low; being the preoperative diagnosis difficult due to the variety in its clinical presentation.

RESUMO Introdução: o termo "mucocele", nome inespecífico e descritivo que se refere a um acúmulo anormal de muco dentro da luz do apêndice, independente da causa subjacente, é uma condição clínica rara, raramente considerada no diagnóstico diferencial das lesões localizado no quadrante inferior direito do abdômen. Objetivo: apresentar um paciente com diagnóstico pré-operatório de apendicite aguda complicada, submetido a cirurgia de urgência e com diagnóstico de mucocele apendicular. Caso clínico: Paciente do sexo masculino, 52 anos, que deu entrada no Pronto Socorro e na Unidade de Terapia Intensiva por apresentar dor em região lombar direita com irradiação para fossa ilíaca direita. Foi acompanhada de náuseas, vômitos profusos, febre 38,5-390 C, sede, oligúria, astenia e anorexia. Discussão: ao exame físico apresentava mucosas pálidas e levemente ressecadas, pulso fraco e taquicárdico, hipotensão arterial, abdome levemente distendido, doloroso à palpação profunda em fossa ilíaca direita. Estudos de imagem sugeriram uma coleção apendicular. Com a suspeita clínica de apendicite aguda complicada e a dúvida diagnóstica, optou-se pela realização de laparotomia exploradora de emergência. No intraoperatório, foi identificada mucocele apendicular. A histologia confirmou uma mucocele apendicular sem evidência de origem neoplásica. A paciente evoluiu satisfatoriamente e recebeu alta hospitalar no quarto dia de pós-operatório. Conclusões: amucocele apendicular é uma condição clínico-cirúrgica que, apesar de conhecida, é muito baixa; sendo o diagnóstico pré-operatório difícil pela variedade de sua apresentação clínica.
