Adaptación y validación del Voice Handicap Index y su versión abreviada al español rioplatense de Argentina

Objetivo: Este estudio tuvo como objetivo principal validar el Voice Handicap Index (VHI) y su versión abreviada (VHI-10) adaptados al español rioplatense de Argentina, con objetivos específicos centrados en evaluar su fiabilidad y validez. Metodología: La adaptación cultural incluyó técnicas de traducción directa, síntesis y retrotraducción, evaluación de la equivalencia semántica y aplicación a un grupo piloto. Para la validación se evaluó la fiabilidad de ambos índices adaptados mediante la consistencia interna (coeficiente alfa de Cronbach) y la estabilidad test-retest (prueba de Bland-Altman, CCI y r de Spearman). Además, se examinó la validez de criterio y de constructo. 213 sujetos participaron en la validación del índice adaptado de 30 ítems (123 disfónicos; 90 de control); 113, en la del índice abreviado (63 disfónicos; 50 de control). Resultados: Se constituyó el Índice de Desventaja Vocal (IDV) como la versión adaptada del VHI al español rioplatense de Argentina. Ambos índices demostraron excelente consistencia interna (IDV-30 α = 0,96; IDV-10 α = 0,92) y estabilidad y concordancia (IDV-30 CCI = 0,95; IDV-10 CCI = 0,96). Se halló alta correlación entre los puntajes de ambos índices y la autoevaluación de la severidad de la disfonía de los participantes (r = 0,85). Ambos índices demostraron capacidad de diferenciar entre individuos con disfonía y sujetos sanos (p< 0,001). El análisis factorial reveló tres factores para el IDV-30 y un factor para el IDV-10. Conclusiones: El IDV-30 e IDV-10 presentan grados adecuados de fiabilidad y validez. Ambos pueden ser incluidos en protocolos de valoración de la función vocal por profesionales de Argentina.

Aim: This study aimed to validate the Voice Handicap Index (VHI) and its abbreviated version (VHI-10) adapted into Rioplatense Spanish from Argentina, with specific goals centered on assessing their reliability and validity. Methods: Cultural adaptation involved direct translation, synthesis and back-translation techniques, followed by an assessment of semantic equivalence and application to a pilot group. For the validation process, the reliability of both adapted indices was assessed through measures of internal consistency (Cronbach's alpha coefficient) and test-retest stability (Bland-Altman test, ICC and Spearman's correlation coefficient). Additionally, we conducted analyses to asses criterion and construct validity. 213 subjects participated in the validation of the adapted 30-items index, (123 with dysphonia; 90 from control group); 113, in the abbreviated version (63 with dysphonia; 50 from control group). Results: The "Índice de Desventaja Vocal" (IDV) was established as the adapted version of the VHI into Rioplatense Spanish from Argentina. Both indeces exhibited excellent internal consistency (IDV-30 α = 0,96; IDV-10 α = 0,92) and satisfactory stability and agreement (IDV-30 CCI = 0,95; IDV-10 CCI = 0,96). Regarding validity, a strong correlation was observed between the scores of both indeces and the participant's self-assessment of dysphonia degree (r = 0,85). Both indices effectively differentiated between individuals with dysphonia and healthy subjects (p< 0,001). Factor analysis revealed three factors for the IDV-30 and one factor for the IDV-10. Conclusion: The IDV-30 and IDV-10 demonstrate satisfactory levels of reliability and validity. Both indices can be incorporated into the assessment protocols for evaluating the vocal function by professionals in Argentina.

Bispectral index monitoring for sedation in scheduled adult colonoscopy: A randomized controlled trial.

BACKGROUND: Patients should be closely monitored during procedures under sedation outside the operating room, but it is unclear which type of monitoring is best. We investigated the efficacy and safety of BIS monitoring vs conventional monitoring for sedation during colonoscopy. METHODS: We performed a double-blind clinical trial in 180 patients undergoing elective colonoscopy. Patients were randomized to 1) the BIS group or 2) a control group, in which sedation was monitored with a BIS monitor or the Ramsay Sedation Score, respectively. The primary outcome was the rate of sedation-induced adverse events in both groups. Secondary outcomes were the characteristics of patients who developed adverse events, and duration of colonoscopy when these events occurred, propofol and remifentanil dosage, and patient satisfaction. RESULTS: Univariate analysis showed fewer cardiopulmonary complications in the BIS group (41.11% vs 57.78% in controls; p = 0.02). Multivariate analysis found a significantly higher risk of adverse events in older patients (95% CI, 1.013-1.091; p = 0.0087) and in men (95% CI, 1.129-7.668; p = 0.0272). These events were observed at the hepatic flexure. No significant differences between propofol or remifentanil dosage, use of rescue medication, and patient satisfaction were observed between groups. CONCLUSIONS: Our data suggest that BIS monitoring during sedation in scheduled colonoscopies reduces adverse respiratory events. Although its routine use in sedation does not appear to be warranted, clinicians should take steps to identify patients with a higher risk of complications who might benefit from this type of monitoring.

Left ventricular concentric remodeling in COPD patients: A cross-sectional observational study.

OBJECTIVE: To investigate the association between left ventricular structure and disease severity in COPD patients. METHODS: Twenty-eight COPD patients were stratified according to the disease severity, using the BODE index, into Lower (n=17) and Higher (n=11) groups, composed of patients with lower severity (BODE <5) and higher severity (BODE ≥5), respectively. Left ventricle (LV) was assessed by 2D-echocardiography. BODE index was calculated using body mass index (BMI); forced expiratory volume in the first second (FEV1, %); modified Medical Research Council (mMRC) and distance walked during 6-minute walk test (6MWD). RESULTS: Patients in the Higher group showed lower oxygen arterial saturation (p=0.02), FEV1 (p<0.01) and 6MWD (p=0.02) and higher value of relative posterior wall thickness (RWT) compared to Lower group (p=0.02). There were significant associations between LV end-systolic diameter (LVESD) and BODE index (r=-0.38, p=0.04), LV end-diastolic diameter (LVEDD) and FEV1 (r=0.44, p=0.02), LVEDD and BMI (r=0.45, p=0.02), LVESD and BMI (r=0.54, p=0.003) and interventricular septal thickness and 6MWD (r=-0.39, p=0.04). CONCLUSIONS: More severe COPD patients, BODE score ≥5, may have higher RWT, featuring a possible higher concentric remodeling of LV in this group. Besides that, a greater disease severity may be related to LV chamber size reduction.

Oscillometric devices vs. arterial Doppler in measuring the ankle-arm index for the diagnosis of peripheral arterial disease. / Dispositivos oscilométricos frente a Doppler arterial en la medida del índice tobillo-brazo para el diagnóstico de la enfermedad arterial periférica.

INTRODUCTION: Peripheral arterial disease is a marker of vascular damage that is diagnosed by measuring the ankle-brachial index. The aim of this study was to determine the validity and agreement of the MESI ABPI-MD and Microlife WatchBP® office-ABI oscillometric devices with respect to the gold standard arterial Doppler. MATERIALS AND METHODS: Observational, cross-sectional, descriptive study of inpatients who underwent ABI measurement with the three devices. Values are considered normal between 1-1.4, indeterminate between 0.91-0.99 and pathological ≤0.9 and >1.4. RESULTS: A total of 187 patients (54.4% male) with a mean age of 66 years were included. The Doppler results were inferior to those of the oscillometric devices (median [IQR] 1.1 [0.2] vs. 1.2 [0.2], P<.05), with no significant differences between the automated devices (P=.29 for the right lower limb and P=.342 for the left lower limb). Both devices had high specificity (96.5-99.2%) and low sensitivity (29.5-45.4%). The correlation of the results was good-moderate for MESI and moderate for Microlife. The agreement between the two was acceptable-moderate. CONCLUSION: Automated oscillometric devices could be useful in asymptomatic patients as an alternative to arterial Doppler.

The evolution of the treatment of esophageal achalasia. Chronicle of a 35-year journey.

Over the last few decades, significant improvement has been made in both the evaluation and treatment of esophageal achalasia. The Chicago classification, today in version 4.0, is now the standard for diagnosis of achalasia, providing a classification into 3 subtypes with important therapeutic and prognostic implications. Therapy, which was at first mostly limited to pneumatic dilatation, today includes minimally invasive surgery and peroral endoscopic myotomy, allowing for a more tailored approach to patients and better treatment of recurrent symptoms. This review chronicles my personal experience with achalasia over the last 35 years, describing the progress made in the treatment of patients with achalasia.

Dermatosis perforante adquirida e Índice de Calidad de Vida en Dermatología en pacientes en hemodiálisis / Acquired perforating Dermatology Life Quality Index in dermatology in patients receiving hemodialysis

Introducción: La dermatosis perforante adquirida (DPA) es un trastorno frecuente en pacientes en hemodiálisis, y el efecto en la calidad de vida está poco descrito. Investigamos la prevalencia de DPA en pacientes en hemodiálisis, medimos y comparamos la calidad de vida asociada a DPA. Métodos: Desarrollamos un estudio prospectivo, observacional y descriptivo. Invitamos a pacientes mayores de 18 años en hemodiálisis. Se obtuvieron datos de su expediente electrónico, y se realizó exploración dermatológica. Se aplicó el Índice de Calidad de Vida en Dermatología (DLQI). Se hizo un análisis descriptivo de las variables demográficas, de las características clínicas y de los hallazgos de dermatoscopia, así como la comparación de los puntajes del DLQI. Resultados: La muestra fue de 46 pacientes, con una prevalencia de DPA del 11%. Los pacientes con DPA eran más delgados y jóvenes en comparación con los pacientes sin DPA. El tiempo en hemodiálisis fue mayor en los pacientes con DPA en comparación a los pacientes sin DPA, con una mediana de 90 versus 32 meses (p=0,015). La afección en calidad de vida fue mayor en los pacientes con DPA en comparación a los pacientes sin DPA, con un algún efecto en todos los pacientes con DPA y un 33% en los pacientes sin DPA (p=0,001). Los pacientes con DPA tuvieron con más frecuencia prurito en comparación con los pacientes sin DPA (p=0,007). Conclusiones: La edad, el tiempo en hemodiálisis y el índice de masa corporal se asocian con la presencia de DPA. Los pacientes con DPA tuvieron una prevalencia más alta de prurito y mayor afección en la calidad de vida en dermatología en comparación con los pacientes sin DPA. (AU)

Introduction: Acquired perforating dermatosis (APD) is a frequent disorder in hemodialysis patients and the effect on the quality of life is poorly described. We investigated the prevalence of APD in hemodialysis patients, measured and compared APD-associated quality of life. Methods: We developed a prospective, observational, and descriptive study. We invited patients over the age of 18 in hemodialysis. Data was obtained from their electronic file and a dermatological examination was performed. The Dermatology Life Quality Index (DLQI) was applied. Descriptive analysis of demographic variables, clinical features, and dermoscopy findings, as well as comparison of DLQI scores, was made. Results: The sample consisted of 46 patients, with a prevalence of APD of 11%. Patients with APD were leaner and younger compared to patients without APD. The time on hemodialysis was longer in patients with APD compared to those without APD, with a median of 90 versus 32 months (P=.015). The impact on quality of life was greater in patients with APD compared to those without APD, with some effect in all patients with APD and 33% in patients without APD (P=.001). Patients with APD had more frequent pruritus compared to those without APD (P=.007). Conclusions: Age, time on hemodialysis and BMI are associated with the presence of APD. Patients with APD had a higher prevalence of pruritus and a greater impact on quality of life in dermatology compared to patients without APD. (AU)

Asociación de la rigidez aórtica con calcificaciones vasculares abdominales y coronarias en pacientes con enfermedad renal crónica estadios 3 y 4 / Association of aortic stiffness with abdominal vascular and coronary calcifications in patients with stage 3 and 4 chronic kidney disease

Fundamento y objetivos: El aumento de la rigidez arterial central (aórtica) tiene repercusiones hemodinámicas con efectos nocivos cardiovasculares y renales. En la enfermedad renal crónica (ERC) puede existir un aumento de la rigidez aórtica secundaria a múltiples alteraciones metabólicas, entre ellas la calcificación de la pared vascular (CV). El objetivo de este estudio fue analizar la asociación de la rigidez aórtica y de la hemodinámica central con la presencia de CV en dos territorios: aorta abdominal (CAA) y arterias coronarias (CC). Material y métodos: Se incluyeron 87 pacientes con ERC estadios 3 y 4. Usando tonometría de aplanamiento se estudiaron la hemodinámica central y la rigidez aórtica. Esta se determinó mediante la velocidad de pulso carótida-femoral (Vpc-f). A partir de la Vpc-f se calculó el índice de la VPc-f (iVpc-f) que considera otras variables que influyen en la Vpc-f, como edad, presión arterial, sexo y frecuencia cardiaca. La presencia de CAA se valoró mediante radiografía lateral de columna lumbar calculándose el índice de Kauppila (iKauppila) y las CC mediante tomografía computarizada multidetección por el método de Agatston, calculándose su índice (iAgatston). Para el estudio de la asociación entre iVpc-f, iKauppila, iAgatston, presión aórtica central, parámetros clínicos y datos de laboratorio se usaron la regresión múltiple y la regresión logística. La capacidad discriminativa del iVpc-f para evaluar la presencia de CAA y CC se determinó mediante el área bajo la curva (ABC) de ROC (receiver-operating characteristic). Resultados: La Vpc-f y el iVpc-f fueron 11,3±2,6m/s y 10,6m/s, respectivamente. El iVpc-f fue mayor cuando la ERC coexistía con diabetes mellitus (DM). Se detectaron CAA y CC en el 77% y el 87%, respectivamente. La albuminuria (β=0,13, p=0,005) y el iKauppila (β=0,36, p=0,001) se asociaron de forma independiente con la magnitud del iVpc-f... (AU)

Rationale and objectives: Increased central (aortic) arterial stiffness has hemodynamic repercussions that affect the incidence of cardiovascular and renal disease. In chronic kidney disease (CKD) there may be an increase in aortic stiffness secondary to multiple metabolic alterations including calcification of the vascular wall (VC). The objective of this study was to analyze the association of central aortic pressures and aortic stiffness with the presence of VC in abdominal aorta (AAC) and coronary arteries (CAC). Materials and methods: We included 87 patients with CKD stage 3 and 4. Using applanation tonometry, central aortic pressures and aortic stiffness were studied. We investigated the association of aortic pulse wave velocity (Pvc-f) and Pvc-f adjusted for age, blood pressure, sex and heart rate (Pvc-f index) with AAC obtained on lumbar lateral radiography and CAC assessed by multidetector computed tomography. AAC and CAC were scored according to Kauppila and Agatston methods, respectively. For the study of the association between iPvc-f index, Kauppila score, Agatston score, central aortic pressures, clinical parameters and laboratory data, multiple and logistic regression were used. We investigated the diagnosis performance of the Pvc-f index for prediction of VC using receiver-operating characteristic (ROC). Results: Pvc-f and Pvc-f index were 11.3±2.6m/s and 10.6m/s, respectively. The Pvc-f index was higher when CKD coexisted with diabetes mellitus (DM). AAC and CAC were detected in 77% and 87%, respectively. Albuminuria (β=0.13, p=0.005) and Kauppila score (β=0.36, p=0.001) were independently associated with Pvc-f index. In turn, Pvc-f index (β=0.39, p=0.001), DM (β=0.46, p=0.01), and smoking (β=0.53; p=0.006) were associated with Kauppila score, but only Pvc-f index predicted AAC [OR: 3.33 (95% CI: 1.6–6.9; p=0.001)]. The Kauppila score was independently associated with the Agatston score (β=1.53, p=0.001)... (AU)

Comparativa de los métodos de evComparativa de los métodos de evaluación de la reserva de yodo corporal previamente a la realización de tratamiento con radioyodoaluación de la reserva de yodo corporal previamente a la realización de tratamiento con radioyodo / Comparison of Body Iodine Pool Assessment Methods Before Radioiodine Therapy

Introducción y objetivos: El tratamiento con yodo radiactivo (RAIT) se recomienda para reducir el riesgo de recurrencia y de metástasis en personas con cáncer diferenciado de tiroides (CDT) de riesgo intermedio-alto. En la preparación para la RAIT, la estimulación de la tirotropina y la reducción en la reserva corporal de yodo son elementos importantes para contribuir al éxito de la terapia. Para ello, se pide a los pacientes que reduzcan la ingesta de este mineral antes de la RAIT, y puede evaluarse su reserva corporal midiendo su excreción por la orina (yoduria) antes del tratamiento. El objetivo de nuestro estudio ha sido comparar los métodos utilizados para medir la reserva de yodo corporal en la evaluación de la eficacia de la dieta con bajo contenido en yodo (RID) aplicada a la preparación del paciente para la RAIT. Pacientes y métodos: Suspendieron la levotiroxina tres semanas antes de la RAIT y fueron controlados con una RID durante las dos semanas previas a la realización del tratamiento 80 pacientes con CDT. Tras dos semanas de RID, en todos se llevó a cabo una recolección de orina de 24h el día previo a la fecha de administración de la RAIT. Los sujetos finalizaron dicha recolección en la mañana de la fecha de RAIT y suministraron una muestra puntual de orina. Se calculó la excreción estimada de creatinina en orina de 24 horas de los pacientes. La estimación de la excreción urinaria de yodo o yoduria (UIE) de 24 horas oras se determinó a partir del índice yodo/creatinina (I/C) obtenido en la muestra de orina puntual de los individuos. Se compararon los resultados de la yoduria de 24 horas, la concentración de yodo en la muestra puntual de orina, el cociente I/C en la muestra puntual de orina y la estimación de la yoduria de 24 horas en los pacientes. Resultados: En 99%, la eficacia de la RID fue suficiente según la yoduria de 24 horas obtenida previamente a la RAIT...(AU)

Introduction and Objectives: Radioactive iodine therapy (RAIT) is recommended to reduce the risk of recurrence and metastasis in patients with intermediate-high risk differentiated thyroid cancer (DTC). In preparation for RAIT, stimulation of thyroid-stimulating hormone and reduction of body iodine pool are important for treatment success. For this purpose, patients are asked to reduce their iodine intake before RAIT, and the body iodine pool can be evaluated by measuring iodine excretion in urine before treatment. The aim of our study is to compare the methods used to measure the body iodine pool in the evaluation of the restricted iodine diet (RID) effectiveness applied in the RAIT preparation. Patients and methods: Eighty DTC patients discontinued levothyroxine three weeks before RAIT and followed up with a RID two weeks before treatment. After two weeks of RID, all patients collected their 24-hour urine the day before the RAIT date. Patients completed 24-hour urine samples on the morning of the RAIT date and also provided a spot urine sample. The estimated 24-hour creatinine excretion of the patients was calculated. Estimated 24-hour urinary iodine excretion (UIE) was calculated using the spot urine iodine/creatinine (I/C) ratio of the patients. 24-hour UIE, iodine concentration in spot urine, I/C ratios in spot urine and estimated 24-hour UIE of the patients were analyzed by comparing with each other. Results: In 99% of the patients, RID efficiency was sufficient according to 24-hour UIE before RAIT. The mean 24-hour UIE was 48.81 micrograms/day (mcg/day) in 24-hour urine samples taken from the patients to evaluate the body iodine pool. The patients’ iodine concentrations in spot urine, I/C ratios in spot urine, and estimated 24-hour UIE were all statistically significantly lower than actual 24-hour UIE, which was the reference method (p: 0.026 vs <0.001 vs 0.041).....

¿Son las escalas de valoración de fragilidad superiores a la escala de valoración ASA en la predicción de complicaciones, estancia hospitalaria y readmisiones en prótesis total de rodilla? Un estudio comparativo entre pacientes octogenarios y septuagenarios / Are frailty scores superior to the ASA score in predicting complications, hospital stay, and readmissions in total knee replacement? A comparative study between octogenarian and septuagenarian patients

Antecedentes y objetivo: Las escalas de valoración de fragilidad no han sido estandarizadas para la evaluación prequirúrgica de pacientes sometidos a un reemplazo total de rodilla (RTR). El objetivo de este estudio fue comparar la eficacia de la escala de valoración de la Sociedad Americana de Anestesiología (ASA), el índice de comorbilidad de Charlson (ICC) y la escala simple de fragilidad (SSF) en la predicción de complicaciones, estancia hospitalaria, reingresos y mortalidad después del RTR electivo. Materiales y métodos: Estudiamos retrospectivamente a 448 pacientes que se sometieron a un RTR por artrosis en nuestra institución entre 2016 y 2019. Estos se dividieron en 2 grupos: grupo A (263 pacientes <80 años) y grupo B (185 pacientes >80 años). Todos fueron clasificados por escalas ASA, ICC y SSF. Resultados: El ICC fue mayor en el grupo B (mediana: 5 [RI: 4-6] vs. 4 [RI: 3-5]; p<0,001); sin embargo, no se asoció con un mayor número de complicaciones. Al realizar un análisis de regresión logística encontramos, para las complicaciones: OR SSF=0,67; ICC=1,11; ASA 3 y 4=0,89 y edad=1,04; mientras que para los reingresos: OR SSF=2,09; ICC=1,01; ASA 3 y 4=0,79 y edad=1. Conclusiones: Las escalas ICC y SSF demostraron no presentar diferencias a la escala ASA en la predicción de reingresos, complicaciones y estancia hospitalaria. Sin embargo, el SSF parece tener una mejor correlación en la predicción de la readmisión no planificada.(AU)

Background and objective: Frailty scores have not been standardized for the preoperative assessment of patients undergoing total knee replacement (TKR). The aim of this study was to compare the efficacy of the American Society of Anesthesiology (ASA) score, the Charlson comorbidity index (ICC) and the simple frailty score (SSF) in predicting complications, hospital stay, readmissions and mortality after elective TKR. Materials and methods: We retrospectively studied 448 patients who underwent TKR for osteoarthritis at our institution between 2016 and 2019. They were divided into two groups: Group A (263 patients, <80 years) and Group B (185 patients, >80 years).). All were classified by ASA, ICC and SSF scores. Results: The ICC was higher in Group B (median 5 [RI: 4-6] vs. 4 [RI: 3-5]; P<.001); however, it was not associated with a higher number of complications. When performing a logistic regression analysis we found, for complications: OR SSF=0.67, ICC=1.11; ASA 3 & 4=0.89 and age=1.04; while for readmissions: OR SSF=2.09; ICC=1.01; ASA 3 & 4=0.79 and age=1. Conclusions: The ICC and SSF scales showed no differences to the ASA scale in the prediction of readmissions, complications and hospital stay. However, the SSF seems to have a better correlation in predicting unplanned readmission.(AU)

Evaluación del valor predictivo negativo de la resonancia magnética multiparamétrica de próstata al combinar su puntuación con parámetros del antígeno prostático específico en pacientes con PSA en zona gris / The effect of the combination of prostate-specific antigen derivatives with multiparametric prostate magnetic resonance imaging scores on the negative predictive value of it in grey zone patients

Objetivo Calcular el valor predictivo negativo (VPN) de la resonancia magnética multiparamétrica (RMmp) de próstata negativa, definida como la ausencia de lesiones en las imágenes, cuando se combina con la densidad del PSA (DPSA) y el índice PSA libre/total (PSA l/t) en pacientes cuyo PSA se encuentra en la zona gris (4-10mg/ml). Métodos Se analizaron 191 pacientes con niveles de PSA entre 4 y 10mg/ml y RMmp negativa. El VPN de la RMmp negativa se calculó de acuerdo con un nivel de DPSA<0,15ng/ml/ml, un índice PSA l/t>0,15 y una combinación de ambos. Los pacientes se dividieron en 3 grupos de riesgo según estos dos parámetros, de la siguiente manera: • DPSA 0,01-0,07ng/ml/ml e índice PSA l/t≥25 en el grupo de bajo riesgo. • DPSA 0,08-0,15ng/ml/ml e índice PSA l/t 0,15-0,24 en el grupo de riesgo intermedio. • DPSA>0,15ng/ml/ml e índice PSA l/t<15 en el grupo de riesgo alto. Resultados El VPN de la RMmp negativa fue del 92,6% para el carcinoma de próstata clínicamente significativo (CPCS). El VPN aumentó al 97,5% en el grupo de riesgo bajo, y disminuyó al 33,3% en el de riesgo alto. El resultado al combinar la RMmp negativa con la DPSA<0,15ng/ml/ml fue muy similar al de su combinación con el PSA l/t>15. Conclusión el índice PSA l/t también podría utilizarse para aumentar el VPN de la RMmp, al igual que la DPSA. No recomendamos evitar la biopsia de próstata con una DPSA>0,15ng/ml/ml y un índice PSA l/t<0,15. Sin embargo, se requieren estudios controlados aleatorizados con más pacientes para confirmar los hallazgos de nuestro estudio. (AU)

Objective To calculate the negative predictive value (NPV) of negative multiparametric prostate magnetic resonance imaging (mpMRI), accepted as no lesions on images, when combined with prostate-specific antigen density (PSAD) and free/total prostate-specific antigen ratio (f/t PSA) in grey zone patients. Methods One hundred ninety-one patients with PSA levels between 4-10mg/ml and negative mpMRI were analyzed. The NPV of negative mpMRI was calculated according to a PSAD level of <0.15 ng/ml/ml, f/t PSA ratio of >0.15, and a combination of both. Patients were divided into three risk groups according to these two parameters: • PSAD 0.01-0.07 ng/ml/ml and f/t PSA ratio ≥25 in a low-risk group. • PSAD 0.08-0.15 ng/ml/ml, and f/t PSA ratio 0.15-0.24 in an intermediate-risk group and high-risk group. • PSAD>0.15 ng/ml/ml and f/t PSA ratio <15 in high-risk group, Results NPV of negative mpMRI was 92.6% for clinically significant prostate carcinoma (CSPCa). It increased to 97.5% in a low-risk group and decreased to 33.3% for CSPCa in a high-risk group. NPV of negative mpMRI results were so close when combined with PSAD <0.15 ng/ml/ml and f/t PSA>15. Conclusion f/t PSA ratio might also be used to increase the NPV of mpMRI, like PSAD. We advise not to avoid prostate biopsy when PSAD is >0.15 ng/ml/ml and the f/t PSA ratio is <0.15. However, we need randomized controlled studies with more patients to confirm our study. (AU)

The association between atherogenic index of plasma and metabolic dysfunction-associated fatty liver disease as detected by FibroScan / Asociación entre el índice aterogénico del plasma y la enfermedad hepática grasa asociadaa disfunción metabólica detectada por FibroScan

Objectives: this study aimed to explore the potential of the atherogenic index of plasma (AIP) as a predictor of metabolic dysfunction-associated fatty liver disease (MAFLD). Methods: a cross-sectional study, including data from 4473 participants in the National Health and Nutrition Examination Survey (NHANES) 2017-2018, was performed. A control attenuation parameter (CAP) ≥ 285 dB/m was used to confirm hepatic steatosis. Degrees of liver stiffness were confirmed according to liver stiffness measurement (LSM). Weighted multivariate logistic regression models were used to assess the association between AIP and the risk for MAFLD and liver fibrosis. Finally, receiver operating characteristic (ROC) curve analysis was used to test the accuracy of AIP in predicting MAFLD. Results: the association between AIP and the prevalence of MAFLD was positive in all three multivariate logistic regression models (model 1, odds ratio (OR), 18.2 (95 % confidence interval (CI), 14.4-23.1); model 2, OR, 17.0 (95 % CI, 13.3-21.8); model 3, OR, 5.2 (95 % CI, 3.9-7.0)). Moreover, this positive relationship was found to be significant in patients of different sexes and whether they had diabetes. However, no significant differences were observed between AIP and significant fibrosis or cirrhosis as assessed by different liver fibrosis indices. Finally, ROC curve analysis demonstrated that the AIP index also demonstrated positive diagnostic utility (area under the ROC curve, 0.733 (95 % CI, 0.718-0.747); p < 0.001). Conclusion: This study revealed a positive association between AIP and MAFLD among American adults. Furthermore, this association persisted in different sexes and whether they had diabetes.(AU)

Objetivos: este estudio tuvo como objetivo explorar el potencial del índice aterogénico del plasma (AIP) como predictor de enfermedad hepática grasa asociada a disfunción metabólica (MAFLD). Métodos: se realizó un estudio transversal que incluyó datos de 4473 participantes de la encuesta nacional de exémenes de salud y nutrición (NHANES) 2017-2018. Se utilizó un parámetro de atenuación de control (CAP) ≥ 285 dB/m para confirmar la esteatosis hepática. Los grados de rigidez hepática se confirmaron de acuerdo con la medición de rigidez hepática (LSM). Se utilizaron modelos de regresión logística multiva-riponderponderados para evaluar la asociación entre AIP y el riesgo de MAFLD y fibrosis hepática. Por último, se utilizó el análisis de la curva ROC para probar la precisión de la AIP en la predicción de la MAFLD.Resultados: la asociación entre AIP y prevalencia de MAFLD fue positiva en los tres modelos de regresión logística multivariable (modelo 1, odds ratio (OR): 18,2 (intervalo de confianza (IC) del 95 %: 14,4-23,1); Modelo 2, OR: 17,0 (IC del 95 %: 13,3-21,8); Modelo 3, OR: 5,2 (IC del 95 %: 3,9-7,0)). Además, esta relación positiva se encontró significativa en pacientes de diferentes sexos ya tuvieran o no diabetes. Sin embargo, no se observaron diferencias significativas entre la AIP y la fibrosis o cirrosis significativa evaluada por diferentes índices de fibrosis hepática. Finalmente, el análisis de la curva ROC demostró que el índice AIP también demostró utilidad diagnóstica positiva (área bajo la curva ROC = 0,733 (IC del 95 %: 0,718-0,747); p < 0,001). Conclusión: este estudio reveló una asociación positiva entre AIP y MAFLD en los adultos estadounidenses. Además, esta asociación persistióen los diferentes sexos ya tuvieran o no diabetes.(AU)

Health-related quality of life and clinical severity in people with epidermolysis bullosa - a proposal for assessing nutritional compromise by body mass index (birmingham Epidermolysis bullosa Severity Score) / Calidad de vida relacionada con la salud y gravedad clínica en personas con epidermólisis bullosa: una propuesta para evaluar el deterioro nutricional por el índice de masa corporal (Birmingham Epidermolysis Bullosa Severity Score)

Introduction and objectives: epidermolysis bullosa (EB) is a rare genetic disease characterised by skin fragility with blisters and erosions on the skin and/or mucous membranes. People with EB often experience several extracutaneous manifestations, including clinical and health-related quality of life (HRQoL) complications. Herein, we evaluate their HRQoL and clinical severity and propose an objective criterion for estimating nutritional compromise using the Birmingham Epidermolysis Bullosa Severity Score (BEBS) tool. Methods: this series of cases included people with EB, monitored by a multi-professional team. Clinical severity was assessed with the BEBS, using body mass index ranges by age, as an objective proposal, to estimate the degree of nutritional compromise. To assess HRQoL, the Children's Dermatology Life Quality Index (individuals aged 4-16 years) and the Quality of Life Evaluation in Epidermolysis Bullosa – Brazilian Portuguese (individuals 17 years and over) were used. Results: of the nine individuals with recessive dystrophic EB (88.9 % female and 12.91 (SD = 11.71) years), the mean total BEBS score was 24.47 (SD = 12.80) points on a scale of 0 to 100 points. Six participants had significant nutritional compromise according to the proposed criteria. Five of the six participants evaluated for HRQoL reported experiencing some impact, with individuals aged 17 and over being more affected and with greater clinical severity. Conclusions: individuals with greater clinical severity of EB experience a more significant impact on their HRQoL. The proposed quantitative criteria for assessing nutritional compromise may help standardise assessments by professionals monitoring the nutritional status of individuals with EB. Keywords: Quality of life. Epidermolysis bullosa. Body mass index.(AU)

Introducción y objetivos: la epidermólisis bullosa (EB) es una rara enfermedad genética caracterizada por fragilidad de la piel con ampollas yerosiones. Las personas con EB experimentan manifestaciones extracutáneas y complicaciones clínicas y de calidad de vida relacionada con la salud (CVRS). Evaluamos la CVRS y la gravedad clínica y proponemos un criterio objetivo para estimar el deterioro nutricional con la herramienta Birmingham Epidermolysis Bullosa Severity Score (BEBS). Métodos: esta serie de casos incluyó pacientes con EB monitoreadas por un equipo multiprofesional. Se evaluó la gravedad clínica con el BEBS utilizando rangos de índice de masa corporal por edad. Para evaluar la CVRS se utilizaron el Children's Dermatology Life Quality Index (individuos de 4 a 16 años) y el Quality of Life Evaluation in Epidermolysis Bullosa – Brazilian Portuguese (individuos de 17 años y más). Resultados: de los nueve individuos con EB distrófica recesiva (88,9 % mujeres y 12,91 (DE = 11,71) años), la puntuación total media del BEBS fue de 24,47 (DE = 12,80) puntos en una escala de 0 a 100 puntos. Seis participantes tenían un deterioro nutricional significativo según los criterios propuestos. Cinco de los seis participantes evaluados en la CVRS informaron experimentar algún impacto, siendo los individuos de 17 años y más los más afectados y con mayor gravedad clínica. Conclusiones: los pacientes con mayor gravedad clínica experimentan un impacto más significativo en su CVRS. Los criterios cuantitativos propuestos para evaluar el deterioro nutricional pueden ayudar a estandarizar las evaluaciones de los profesionales que monitorean el estadonutricional de las personas con EB.

Geographic Comparison of Dietary Intake and Quality in Manitoba Adolescents.

Purpose: The Food and Nutrition for Manitoba Youth (FANS) study examined dietary intakes, food behaviours, food security status, health indicators, and body mass index of a cohort of grade 9 students. This paper describes regional differences and similarities in dietary intake (food and nutrients) and quality of youth participants in the FANS study.Methods: Grade 9 students completed a web-based survey on dietary intakes (24-hour recall), food behaviours, self-reported health indicators, and sociodemographic variables. Nutrient intakes were compared with national guidelines and diet quality was assessed using a modified Healthy Eating Index.Results: A total of 1587 students participated from northern, rural, and urban regions in Manitoba. Northern and rural students had higher intakes of sugar, sodium, and saturated fat compared with urban. Northern students consumed fewer grain products compared to urban, and more servings of "other" foods compared with rural and urban. While most participants were classified into the "needs improvement" or "poor" Healthy Eating Index categories, significantly more northern participants were in the "poor" category.Conclusions: Most adolescents in the study are at nutritional risk; however, there are additional vulnerabilities for those in rural and northern communities. Dietitians can use results to advocate for and plan interventions to improve adolescent nutrition.

Comparison of perioperative outcomes in obese and non-obese patients subjected to open lumbar spine surgery.

OBJECTIVE: Obesity is a global epidemic affecting developing countries. The relationship between obesity and perioperative outcomes during elective lumbar spine surgery remains controversial, especially in those without morbid disease. MATERIALS AND METHODS: We retrospectively revised the medical records of patients with lumbar spine degeneration subjected to elective surgery. The data retrieved included demographic and clinical characteristics, body mass index (BMI), obesity status (BMI ≥ 30), surgical interventions, estimated blood loss (EBL), operative time, length of stay (LOS), and post-operative complications. Perioperative outcomes were compared between Grade I-II obese and non-obese individuals. RESULTS: We enrolled 53 patients, 18 with Grade I-II obesity. Their median age was 51, with no differences in gender, comorbidities, laboratory parameters, and surgical procedures received between groups. No clinically relevant differences were found between grade I-II obese and non-obese participants in EBL (300 mL vs. 250 mL, p = 0.069), operative time (3.2 h vs. 3.0 h, p = 0.037), and LOS (6 days vs. 5 days, p = 0.3). Furthermore, BMI was not associated with the incidence of significant bleeding and long stay but showed a modest correlation with operative time. CONCLUSION: Grade I-II obesity does not increase surgical complexity nor perioperative complications during open lumbar spine surgery.

OBJETIVO: La obesidad es una epidemia mundial que afecta a países subdesarrollados. Su relación con los resultados de la cirugía de columna lumbar electiva sigue siendo controvertida, especialmente en obesos sin enfermedad mórbida. MÉTODOS: Se revisaron los expedientes de pacientes con degeneración de la columna lumbar sometidos a cirugía. Los datos recuperados incluyeron características demográficas y clínicas, índice de masa corporal (IMC), estado de obesidad (IMC > 30), intervenciones quirúrgicas, sangrado estimado, tiempo operatorio, tiempo de estancia y complicaciones. Los resultados se compararon entre individuos obesos grado I-II y controles. RESULTADOS: Se incluyeron 53 pacientes, 18 con obesidad de grado I-II. La edad media fue de 51 años, sin diferencias en el sexo, las comorbilidades, los parámetros de laboratorio y los procedimientos quirúrgicos recibidos entre grupos. No se encontraron diferencias relevantes entre los participantes obesos y los no obesos en sangrado (300 vs. 250 mL, p = 0.069), tiempo operatorio (3.2 vs. 3.0 horas, p = 0.037) y estancia (6 vs. 5 días, p = 0.3). El IMC no se asoció con hemorragia y larga estancia, pero mostró una correlación modesta con el tiempo operatorio. CONCLUSIONES: La obesidad grado I-II no predispone a complicaciones durante la cirugía de columna lumbar.

Real-world Safety and Efficacy of Risankizumab in Psoriatic Patients: A Multicenter, Retrospective, and Not-interventional Study.

BACKGROUND AND OBJECTIVE: Risankizumab - a humanized monoclonal antibody that targets the p19 subunit of IL-23 - has been recently approved to treat moderate-to-severe plaque psoriasis. Real-world data based on a representative pool of patients are currently lacking. OBJECTIVE: To assess the mid- and long-term safety and efficacy profile of risankizumab in patients with moderate-to-severe psoriasis in the routine clinical practice. METHODS: This was a retrospective and multicenter study of consecutive psoriatic patients on risankizumab from April 2020 through November 2022. The primary endpoint was the number of patients who achieved a 100% improvement in their Psoriasis Area and Severity Index (PASI) (PASI100) on week 52. RESULTS: A total of 510 patients, 198 (38.8%) women and 312 (61.2%) men were included in the study. The mean age was 51.7±14.4 years. A total of 227 (44.5%) study participants were obese (body mass index [BMI] >30kg/m2). The mean baseline PASI score was 11.4±7.2, and the rate of patients who achieved PASI100 on week 52, 67.0%. Throughout the study follow-up, 21%, 50.0%, 59.0%, and 66% of the patients achieved PASI100 on weeks 4, 16, 24, and 40, respectively. The number of patients who achieved a PASI ≤2 was greater in the group with a BMI ≤30kg/m2 on weeks 4 (P=.04), 16 (P=.001), and 52 (P=.002). A statistically significantly greater number of patients achieved PASI100 in the treatment-naïve group on weeks 16 and 52 (P=.001 each, respectively). On week 16 a significantly lower number of participants achieved PASI100 in the group with psoriatic arthropathy (P=.04). Among the overall study sample, 22 (4.3%) patients reported some type of adverse event and 20 (3.9%) discontinued treatment. CONCLUSIONS: Risankizumab proved to be a safe and effective therapy for patients with moderate-to-severe psoriasis in the routine clinical practice.

Identification of prognostic factors for survival in patients with metastatic gastric adenocarcinoma in a Mexican population.

INTRODUCTION AND AIMS: Gastric adenocarcinoma is among the high-ranking tumors, with respect to frequency and mortality, worldwide. The inflammatory process and immune system activity are associated with oncologic control. Our aim was to identify whether the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and other variables are prognostic factors for survival in patients with metastatic gastric cancer in a Mexican population. MATERIAL AND METHODS: Patients diagnosed with metastatic gastric adenocarcinoma, hospitalized within the time frame of December 2011 to 2021, were analyzed. The NLR, PLR, and albumin and hemoglobin levels obtained from blood samples were calculated. Functional status (ECOG and Karnofsky), sex, histology, and the presence of signet ring cells were also considered possible prognostic factors. Each factor's prognostic value for overall survival was determined through univariate and multivariate analyses. RESULTS: The study included 956 patients diagnosed with metastatic gastric cancer, of whom 494 (51.7%) were men and 462 (48.3%) were women. The main histologic finding was diffuse adenocarcinoma (n = 619, 64.7%), followed by intestinal adenocarcinoma (n = 293, 30.6%), and the presence of signet ring cells was found in 659 (68.9%) patients. Diagnostic laparoscopy was performed on 238 patients (24.9%) to confirm peritoneal carcinomatosis. The multivariate analysis showed that an NLR above 3.2 (HR 1.51, 95% CI 1.27-1.8; p < 0.001), albumin below 3.5 g/dl (HR 1.25, CI 1.06-1.47; p = 0.006), and an ECOG performance status of 2 or higher (HR 1.39, CI 1.10-1.76; p = 0.005) were independent factors that predicted a lower survival rate, whereas a Karnofsky score above 70% (HR 0.69, CI 0.53-0.91; p = 0.008) was associated with a better survival rate. Lastly, the PLR was not statistically significant in the multivariate analysis. CONCLUSIONS: The NLR, nutritional status assessed through albumin measurement, and functional status can act as independent prognostic survival factors in hospitalized Mexican patients diagnosed with metastatic gastric adenocarcinoma and be taken into account during therapeutic decision-making.

Safety and efficacy of candesartan versus valsartan combined with amlodipine on peripheral and central blood pressure / Seguridad y eficacia de candesartán frente a valsartán combinado con amlodipino sobre la presión arterial periférica y central

Introduction: “Amlodipine/valsartan” or “amlodipine/candesartan” combinations represent two effective antihypertensive agents with complementary mechanisms of action. Nevertheless, a study has yet to be done to evaluate the effect of amlodipine/candesartan on central blood pressure and compare it with amlodipine/valsartan combination. To see how “amlodipine plus candesartan combination” reduces peripheral and central blood pressure compared to the most studied combination, “amlodipine plus valsartan”. Material and methods: Eighty-six patients were randomized in an open-label, prospective study by 1:1 ratio to two groups. Group I (n=42) received the amlodipine and valsartan combination, and group II (n=44) received the amlodipine and candesartan combination. Peripheral and central blood pressure (CBP) was measured at baseline, at 6 and 12 weeks of follow-up. Discussion: Both treatment groups reduced peripheral systolic, diastolic, and mean blood pressure. There was no significant difference between and within both groups. The amlodipine/candesartan combination showed more reduction in peripheral systolic blood pressure (PSBP) after 12 weeks of treatment (p=<0.001). Both groups decreased CBP without significant differences between groups. The amlodipine/candesartan combination showed additional efficacy in decreasing CSBP after 12 weeks (p=<0.001). The two treatment groups did not exert significant efficacy in lowering heart rate (HR) and augmentation index% (AIx%). Conclusion: To conclude, the amlodipine 10mg/candesartan 16mg combination was non-inferior to the amlodipine 10mg/valsartan 160mg combination in terms of reducing peripheral and CBP over time.(AU)

Introducción: «Las combinaciones de amlodipino/valsartán» o «amlodipino/candesartán» representan 2 agentes antihipertensivos efectivos con mecanismos de acción complementarios. Sin embargo, aún no se ha realizado un estudio para evaluar el efecto del amlodipino/candesartán en la presión arterial central y compararlo con la combinación amlodipino/valsartán. En este estudio, se comparó la reducción de la presión arterial periférica y central entre estas 2 combinaciones. Materiales y métodos: Ochenta y seis pacientes fueron asignados aleatoriamente a 2 grupos: el Grupo I (n=42) recibió amlodipino y valsartán, y el Grupo II (n=44) recibió amlodipino y candesartán. Se midió la presión arterial periférica y central al inicio, a las 6 y 12 semanas de seguimiento. Discusión: Ambos grupos redujeron la presión arterial periférica de manera similar, pero la combinación amlodipino/candesartán mostró una mayor reducción en la presión arterial sistólica periférica después de 12 semanas de tratamiento. Ambas combinaciones también disminuyeron la presión arterial central, pero nuevamente, la combinación amlodipino/candesartán tuvo una mayor eficacia en la reducción de la presión arterial sistólica central después de 12 semanas. No se observaron diferencias significativas en la frecuencia cardíaca ni en el índice de aumento entre los grupos. Conclusión: En conclusión, la combinación de amlodipino 10mg/candesartán 16mg demostró ser tan efectiva como la combinación de amlodipino 10mg/valsartán 160mg en la reducción tanto de la presión arterial periférica como central a lo largo del tiempo.(AU)

Metabolic syndrome in systemic lupus erythematosus patients under Mediterranean diet / Síndrome metabólico en pacientes con lupus eritematoso sistémico con patrón de dieta mediterránea

Background and aims: Metabolic syndrome (MetS) is a chronic proinflammatory and prothrombotic condition that exacerbates insulin resistance, oxidative damage, and cardiovascular risk, being more prevalent in patients with systemic lupus erythematosus (SLE), a chronic multisystemic autoimmune disorder. This study aim was to determine the prevalence of MetS and associations with SLE clinical characteristics, cardiovascular risk and dietary pattern in a population of Spanish SLE patients. Design and methods: Cross-sectional study of 293 patients was conducted (90.4% females; mean age 46.8 (12.94)). The diagnosis of MetS was established based on the criteria of the National Cholesterol Education Program Adult Treatment Panel III. SLE Disease Activity Index (SLEDAI-2K) and SDI Damage Index were used to assess disease activity and disease-related damage, respectively. Med Diet adherence was assessed through a 14 items questionnaire on food consumption frequency and habits. Results: MetS was present in 15% SLE patients. Triglycerides, high-density lipoprotein cholesterol, systolic blood pressure and waist circumference were significantly increased (p<0.001) in the group of MetS patients. Patients with MetS showed significantly increased SDI damage index (1.70 (1.69) vs 0.88 (1.12), p<0.001) and complement C3 level (118.70 (32.67) vs 107.55 (26.82), p=0.011). No significant differences were observed according to Med Diet adherence level. Conclusion: We observed a lower prevalence of MetS in SLE than that reported in previous studies, which may be a result of the good level of adherence to the MedDiet in our study sample. Additionally, MetS was associated with higher SDI and complement C3 levels but no with medication use.(AU)

Antecedentes y objetivos: El síndrome metabólico (SM) es una condición crónica proinflamatoria y protrombótica que exacerba resistencia a insulina, daño oxidativo y riesgo cardiovascular, más prevalente en pacientes con lupus eritematoso sistémico (LES) y trastorno autoinmune multisistémico crónico. El objetivo del estudio fue determinar la prevalencia de SM y asociación con características clínicas del LES, riesgo cardiovascular y patrón dietético en pacientes españoles con LES. Diseño y métodos: Estudio transversal, 293 pacientes (90,4% mujeres; edad media 46,85 [12,94]). Diagnóstico de SM según criterios National Cholesterol Education Program Adult Treatment Panel III. Se utilizó el Índice de Actividad de la Enfermedad del LES (SLEDAI-2K) e Índice de Daño del LES para evaluar actividad de la enfermedad y el daño relacionado con la enfermedad. Adherencia a la dieta mediterránea (DM) se evaluó mediante un cuestionario de 14 ítems sobre frecuencia y hábitos de consumo de alimentos. Resultados: El 15% de los pacientes con LES presentaron SM. Encontramos triglicéridos, colesterol de lipoproteínas de alta densidad, presión arterial sistólica y perímetro cintura significativamente elevados (p<0,001) en pacientes con SM. Pacientes con SM mostraron índice de daño SDI (1,70 [1,69] vs. 0,88 [1,12]; p<0,001) y nivel de complemento C3 (118,70 [32,67] vs. 107,55 [26,82]; p=0,011) significativamente elevados. No diferencias significativas según el nivel de adherencia a la DM. Conclusiones: Observamos menor prevalencia de SM en pacientes con LES que la descrita en estudios previos, podría deberse a la buena adherencia a la DM en nuestra muestra. El SM se asoció con mayores niveles de SDI y complemento C3, no con el uso de medicación.(AU)

Análisis integral de la colecistectomía en una unidad de cirugía ambulatoria y corta estancia. Experiencia de los últimos 7 años / Integral analysis of cholecystectomy in an outpatient surgery and short-stay unit. Experience of the last 7 years

Introducción: La colecistectomía laparoscópica ambulatoria (CLA) se considera en la actualidad un trazador representativo de la calidad de un servicio de cirugía general. La gran diversidad de unidades de cirugía ambulatoria dificulta la comparativa de los diferentes indicadores de calidad. Objetivo: Conocer los resultados del manejo de la CLA en un centro integrado y como afecta a sus indicadores de calidad. Pacientes y método: Estudio observacional prospectivo entre 2015 y 2021 de las colecistectomías programadas en unidad integrada. Resultados: Se intervinieron 887 pacientes, el 76,5 % (n = 679) programados en régimen ambulatorio. La pernocta no planificada (PNP) media fue del 25,2 % (n = 171), siendo el índice de sustitución del 57,8 %. Las principales causas de PNP fueron: intolerancia digestiva (48,5 %), cirugía compleja (29,2 %) y el dolor (12,8 %). Los tiempos quirúrgicos fueron superiores en los pacientes en régimen de ingreso (p < 0,001) y en aquellos que causaron PNP (p < 0,001). Un tiempo quirúrgico superior a los 45 minutos fue causa de PNP de forma significativa (p = 0,007). La tasa global de infección de sitio quirúrgico fue del 3,1 %,siendo la infección profunda del 0,59 %. Ningún paciente reingresó en las primeras 24 horas, siendo la asistencia a urgencias a 30 días del 8,2 % (n = 73),reingresando el 1,91 % (n = 17) de los pacientes, con una tasa de reintervención del 0,35 % (n = 3). La tasa de fístula biliar fue del 0,67 %. Conclusión: La CLA es una técnica segura y expansiva, aunque la obtención de parámetros de calidad estandarizados es complejo por la diversidad de unidades.(AU)

Introduction: Ambulatory laparoscopic cholecystectomy (ALC) is currently considered a representative tracer of the quality of a general surgery service. The great diversity of day surgery units makes it difficult to compare the different quality index. Objective: To know the results of the management of the CLA in an integrated center and how it affects its quality index. Patients and method: Prospective observational study between 2015 and 2021 of scheduled cholecystectomies in an integrated unit. Results: 887 patients were operated on, 76.5 % (n = 679) programmed on an outpatient basis. The average unplanned overnight stay (PNP) was 25.2 % (n = 171), with the replacement rate being 57.8 %. The main causes of PNP were: digestive intolerance (48.5 %), complex surgery (29.2 %) and pain (12.8 %). Surgical times were higher in patients on admission (p < 0.001) and in those who caused PNP (p < 0.001). Surgical time greater than 45 minutes was a significant cause of PNP (p = 0.007). The overall rate of surgical site infection was 3.1 %, with deep infection being 0.59 %. No patient was readmitted in the first 24 hours, with 30-day emergency care being 8.2 % (n = 73), readmission rate of 1.91 % (n = 17), with a reoperation rate of 0.35 % (n = 3). The biliary fistula rate was 0.67 %. Conclusion: CLA is a safe and expansive technique, although obtaining quality standard parameters is complex due to the diversity of units.(AU)
