Associated factors with the occurrence of in-hospital cardiac arrest in patients admitted to internal medicine wards for non-cardiovascular causes. / Factores asociados a la ocurrencia de paro cardiaco intrahospitalario en pacientes ingresados en salas de medicina interna por causas no cardiovasculares.

BACKGROUND AND OBJECTIVE: In-hospital cardiac arrest (IHCA) has a low survival rate, so it is essential to recognize the cases with the highest probability of developing it. The aim of this study is to identify factors associated with the occurrence of IHCA. MATERIAL AND METHODS: A single-center case-control study was conducted including 65 patients admitted to internal medicine wards for non-cardiovascular causes who experienced IHCA, matched with 210 admitted controls who did not present with IHCA. RESULTS: The main reason for admission was pneumonia. The most prevalent comorbidity was arterial hypertension. Four characteristics were strongly and independently associated with IHCA presentation, these are electrical left ventricular hypertrophy (LVH) (OR: 13.8; 95% IC: 4.7-40.7), atrial fibrillation (OR: 9.4: 95% CI: 4.3-20.6), the use of drugs with known risk of torsades de pointes (OR: 2.7; 95% CI: 1.3-5.5) and the combination of the categories known risk plus conditional risk (OR: 17.1; 95% CI: 6.7-50.1). The first two detected in the electrocardiogram taken at the time of admission. CONCLUSION: In admitted patients for non-cardiovascular causes, the use of drugs with a known risk of torsades de pointes, as well as the detection of electrical LVH and atrial fibrillation in the initial electrocardiogram, is independently associated with a higher probability of suffering a IHCA.

Response predictors to cardiac resynchronization therapy in chronic heart failure: a 10-year-cardiovascular center experience.

BACKGROUND: Cardiac resynchronization therapy (CRT) has been established as an effective therapy for heart failure with reduced ejection fraction. Randomized clinical trials have shown its impact on mortality and HF hospitalizations, as well as improvement of symptoms and quality of life. OBJECTIVES: Finding clinical, electrocardiographic, and echocardiographic variables that may predict the response to cardiac resynchronization therapy (CRT). METHODS: We performed a single-center, observational, analytic, and retrospective study that included 102 patients with heart failure (HF) diagnosis who underwent CRT according to guideline-directed therapy from January 2010 to April 2020 in a third-level center. CRT response was defined as an improvement of New York Heart Association functional class in at least 1 category associated with a recovery of ≥ 5% in the left ventricular ejection fraction (LVEF). RESULTS: Our study population was 102 patients of which 61 (59.8%) were men. The mean age at HF diagnosis was 54 ± 18.7 years. Ischemic heart disease was the etiology in 37 (36.3%) cases. Fifty-one (50%) patients were classified as responders. Responders had wider QRS, and lower LVEF and right ventricular fractional area change at baseline. After CRT, responders had a greater reduction of QRS duration, and improvement in LVEF, global longitudinal strain, and echocardiographic dyssynchrony parameters. Multivariate regression analysis showed that left bundle branch block (LBBB), left ventricular end-diastolic volume (LVEDV), tricuspid annular plane systolic excursion (TAPSE), and baseline difference of pre-ejection periods were predictors of a positive response to CRT in this population. CONCLUSIONS: LBBB, TAPSE, LVEDV, and pre-ejection time difference are independent variables that can predict adequate response to CRT.

ANTECEDENTES: La terapia de resincronización cardíaca (TRC) se ha establecido como una terapia efectiva para la insuficiencia cardíaca con fracción de eyección reducida. Ensayos clínicos aleatorizados han demostrado su impacto en la mortalidad y hospitalizaciones por insuficiencia cardíaca, así como la mejora de los síntomas y la calidad de vida. OBJETIVOS: Determinar las variables clínicas, electrocardiográficas y ecocardiográficas que puedan predecir la respuesta a la terapia de resincronización cardíaca (TRC). MÉTODO: Estudio unicéntrico, observacional, analítico, retrospectivo, que incluyó 102 pacientes con diagnóstico de IC sometidos a TRC y terapia dirigida por guías, de enero de 2010 a abril de 2020, en un centro de tercer nivel. La respuesta a TRC fue definida como mejoría de la clase funcional de la New York Heart Association en al menos 1 categoría, asociado con una recuperación ≥ 5% en la fracción de expulsión del ventrículo izquierdo (FEVI). RESULTADOS: Incluimos a 102 pacientes, 61 (59.8%) fueron hombres. El promedio de edad al diagnóstico de IC fue 54 ± 18.7 años. La cardiopatía isquémica fue la etiología en 37 (36.3%) pacientes. 51 (50%) pacientes, fueron clasificados como respondedores. Los respondedores presentaron QRS amplio, menor FEVI y menor fracción de acortamiento del ventrículo derecho al inicio del estudio. Después de la TRC, los respondedores tuvieron una mayor reducción en la duración del QRS, mejoría en la FEVI, strain longitudinal global y parámetros de disincronía ecocardiográfica. El análisis de regresión multivariado mostró que el bloqueo de rama izquierdo (BRI), el volumen telediastólico del ventrículo izquierdo (VTDVI) la excursión sistólica del plano anular tricuspídeo (TAPSE) y la diferencia basal del período expulsivo fueron predictores de respuesta positiva a TRC. CONCLUSIONES: BRI, TAPSE, VTDVI y la diferencia basal de períodos preexpulsivos son variables independientes que predicen respuesta adecuada a TRC.

Predictors of first-year postoperative complications after fixation of low-energy ankle fractures: A single-center, retrospective cohort study of 663 consecutive fractures. / [Artículo traducido] Predictores de las complicaciones postoperatorias en el primer año tras la fijación de fracturas de tobillo de baja energía. Estudio de cohortes retrospectivo sobre 663 fracturas intervenidas consecutivamente en un único centro.

INTRODUCTION: Rotational ankle fractures are common, have diverse personalities and affect both robust and fragile patients. Postoperative complications are frequent, creating a sizeable economic burden. The primary purpose of this study was to expand current knowledge on predictors of postoperative complications after low-energy ankle fracture fixation. MATERIALS AND METHODS: A retrospective single-center cohort study was completed of patients undergoing internal fixation OF low-energy ankle fractures. The primary outcome was first-year postoperative complications, classified as major (surgical) or minor (non-surgical). Data on patients, their injuries, and treatments were collected. To identify potential predictors of outcomes, logistic regression methods were used, with a backward-stepwise method used for model fitting. RESULTS: In total, 663 patients of median age 59 years were analysed. We found a high rate of complications (28.4%), with wound-healing issues and infections predominant. Overall, 14.8% had minor complications, while 13.6% required an unplanned reoperation. On multivariable analysis, the most consistent predictors of complications were older age (OR: 1.02 per year), longer operating time (3.32 per hour), and smoking (2.91). CONCLUSIONS: Older patients and smokers who sustain fractures requiring more complex surgery are at higher risk of postoperative complications.

Determining factors on length of stay in primary total knee arthroplasty patients using enhanced recovery protocol after surgery (ERAS) pathway. / Factores determinantes de la duración de la estancia hospitalaria en pacientes operados de artroplastia primaria total de rodilla usando un protocolo de recuperación mejorada (ERAS).

INTRODUCTION: There is an increase in degenerative arthropathies because of the increase in the longevity of world's population, making primary knee arthroplasties a procedure to recover quality of life without pain. There are factors associated with the length of hospital stay after this procedure. OBJECTIVE: To determine the risk factors influencing the hospital stay during the postoperative period of patients undergoing primary total knee arthroplasty with an enhanced recovery after surgery protocol (ERAS). METHODS: A retrospective study is carried out on patients undergoing primary total knee arthroplasty at an University Hospital in the period 2017-2020 using the ERAS protocol, during which 957 surgeries were performed. RESULTS: Average age of 71.7±8.2years, 62.4% were women and the 77.3% were classified as ASAII. The significantly associated factors to an increased length of stay are: age (P=.001), ASA scale (P=.04), day of surgery (P<.001), blood transfusion (P<.001), postoperative hemoglobin level at 48-72h (P<.001), the time of first postoperative mobilization to ambulate and climb stairs (P<.001), the need for analgesic rescues (P=.003), and the presence of postoperative nausea and vomiting (P=.008). CONCLUSIONS: There are statistically significant and clinically relevant factors associated with hospital stay. Determining these factors constitutes an advantage in hospital management, in the development of strategies to improve and optimize the quality of care and available health resources.

Development and validation of a prognostic nomogram for the renal relapse of lupus nephritis / Desarrollo y validación de un nomograma pronóstico para la recaída renal de la nefritis lúpica

Objectives This study aims to assess the risk of relapse after complete remission (CR) and partial remission (PR), and to develop a prognostic nomogram predicting the probability in lupus nephritis (LN) patients. Methods Data from patients with LN who had been in remission were collected as a training cohort. The prognostic factors were analyzed using the univariable and multivariable Cox model for the training group. A nomogram was then developed using significant predictors in multivariable analysis. Both discrimination and calibration were assessed by bootstrapping with 100 resamples. Results A total of 247 participants were enrolled, including 108 in the relapse group and 139 in the no relapse group. In multivariate Cox analysis, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI), erythrocyte sedimentation rate (ESR), complement 1q (C1q), and antiphospholipid (aPL), anti-Sm antibody were found to be significant for predicting relapse rates. The prognostic nomogram including the aforementioned factors effectively predicted 1- and 3-year probability of flare-free. Moreover, a favorable consistency between the predicted and actual survival probabilities was demonstrated using calibration curves. Conclusions High SLEDAI, ESR, and positive aPL, anti-Sm antibody are potential risk factors for LN flare, while high C1q can reduce its recurrence. The visualized model we established can help predict the relapse risk of LN and aid clinical decision-making for individual patients (AU)

Objetivos Este estudio pretende evaluar el riesgo de recaída tras la remisión completa y la remisión parcial, y desarrollar un nomograma pronóstico que prediga la probabilidad en pacientes con nefritis lúpica (NL). Métodos Se recogieron datos de pacientes con NL que habían estado en remisión como cohorte de entrenamiento. Se analizaron los factores pronósticos utilizando el modelo COX univariable y multivariable para el grupo de entrenamiento. A continuación se desarrolló un nomograma utilizando los predictores significativos en el análisis multivariable. Tanto la discriminación como la calibración se evaluaron mediante bootstrapping con 100 remuestreos. Resultados Se inscribió a un total de 247 participantes, incluidos 108 en el grupo de recaída y 139 en el grupo sin recaída. En el análisis multivariante de Cox, el índice de actividad de la enfermedad lúpica eritematosa sistémica (SLEDAI), la velocidad de sedimentación globular (VSG), el complemento 1q (C1q) y los anticuerpos antifosfolípidos (aPL) y anti-Sm resultaron significativos para predecir las tasas de recaída. El nomograma pronóstico que incluía los factores mencionados predijo eficazmente la probabilidad a 1 y a 3 años de estar libre de reagudizaciones. Además, se demostró una coherencia favorable entre las probabilidades de supervivencia previstas y las reales mediante curvas de calibración. Conclusiones SLEDAI alto, VSG y aPL positivo, anticuerpos anti-Sm son factores de riesgo potenciales de reagudización de la NL, mientras que C1q alto puede reducir su recurrencia. El modelo visualizado que establecimos puede ayudar a predecir el riesgo de recidiva de la NL y ayudar a la toma de decisiones clínicas para pacientes individuales (AU)

Improvement of left ventricular ejection fraction in patients with heart failure with reduced ejection fraction: Predictors and clinical impact / Impacto clínico a medio plazo de la mejoría de la fracción de eyección ventricular izquierda en pacientes con insuficiencia cardiaca con fracción de eyección reducida

Background A percentage of patients with heart failure with reduced ejection fraction (HFrEF) improve left ventricular ejection fraction (LVEF) in the evolution. This entity, defined for the first time in an international consensus as heart failure with improved ejection fraction (HFimpEF), could have a different clinical profile and prognosis than HFrEF. Our main aim was to analyze the differential clinical profile between the two entities, as well as the mid-term prognosis. Material-methods Prospective study of a cohort of patients with HFrEF who had echocardiographic data at baseline and follow-up. A comparative analysis of patients who improved LVEF with those who did not was made. Clinical, echocardiographic and therapeutic variables were analyzed, and the mid-term impact in terms of mortality and hospital readmissions for HF was assessed. Results Ninety patients were analyzed. Mean age was 66.5(10.4) years, with a male predominance (72.2%). Forty five patients (50%) improved LVEF (Group-1,HFimpEF) and forty five patients (50%) sustained reduced LVEF (Group-2,HFsrEF). The mean time to LVEF improvement in Group-1 was 12.6(5.7) months. Group-1 had a more favorable clinical profile: lower prevalence of cardiovascular risk factors, higher prevalence of de novo HF (75.6% vs. 42.2%; p<0.05), lower prevalence of ischemic etiology (22.2% vs. 42.2%; p<0.05), with less basal dilatation of the left ventricle. At the end of follow-up (mean 19(1) months) Group-1 had a lower hospital readmission rate (3.1% vs. 26.7%; p<0.01), as well as lower mortality (0% vs. 24.4%; p<0.01). Conclusion Patients with HFimpEF seem to have a better mid-term prognosis in terms of reduced mortality and hospital admissions. This improvement could be conditioned by the clinical profile of patients HFimpEF (AU)

Introducción Un porcentaje de pacientes con insuficiencia cardiaca y fracción de eyección reducida (IC-FEr) mejoran la fracción de eyección ventricular izquierda (FEVI) en la evolución. Esta entidad se ha definido por primera vez en un consenso internacional como insuficiencia cardiaca y fracción de eyección mejorada (IC-FEm), y podría tener un perfil y pronóstico diferente que IC-FEr. Nuestro objetivo fue analizar el perfil de ambas entidades y su pronóstico a medio plazo. Material y métodos Estudio prospective de una cohorte de pacientes con IC-FEr que tenían datos ecocardiográficos basales y en el seguimiento. Se hizo un análisis comparativo de pacientes con IC-FEm y pacientes con insuficiencia cardiaca y IC-FEpr. Se analizaron variables clínicas, ecocardiográficas y de tratamiento; el impacto clínico a medio plazo se analizó en términos de mortalidad y reingresos hospitalarios por insuficiencia cardiaca. Resultados Se analizaron 90 pacientes, edad media 66,5 (10,4) años (72,2% mujeres). La mitad de los pacientes mejoraron su FEVI, con un tiempo medio hasta la mejoría de 12,6 (5,7) meses. El grupo IC-FEm tenía un perfil clínico más favorable: menor proporción de factores de riesgo cardiovascular, prevalencia más elevada de IC-novo (75,6 vs. 42,2%; p < 0,05), y menor proporción de isquemia (22,2 vs. 42.2%; p < 0,05). Los pacientes con IC-FEm en el seguimiento a medio plazo tenían menor tasa de reingresos (3,1 vs. 26,7%; p < 0,01), y mortalidad (0 vs. 24,4%; p < 0,01). Conclusión Pacientes con IC-FEm parecen tener un mejor pronóstico en términos de mortalidad y reingresos hospitalarios por insuficiencia cardiaca (IC). Esta mejoría clínica podría estar condicionada por el perfil de los pacientes con IC-FEm (AU)

Parent-led stepped care for traumatised children: parental factors that predict treatment completion and response.

Background: Stepped care cognitive behavioural therapy for children after trauma (SC-CBT-CT; aged 7-12 years) can help to increase access to evidence-based trauma treatments for children. SC-CBT-CT consists of a parent-led therapist-assisted component (Step One) with an option to step up to standard therapist-led treatment (Step Two). Studies have shown that SC-CBT-CT is effective; however, less is known about what parent variables are associated with outcome of Step One.Objective: To examine parent factors and their relationship with completion and response among children receiving Step One.Method: Children (n = 82) aged 7-12 (M = 9.91) received Step One delivered by their parents (n = 82) under the guidance of SC-CBT-CT therapists. Logistic regression analyses were used to investigate whether the following factors were associated with non-completion or non-response: the parents' sociodemographic variables, anxiety and depression, stressful life experiences and post-traumatic symptoms, negative emotional reactions to their children's trauma, parenting stress, lower perceived social support, and practical barriers to treatment at baseline.Results: Lower level of educational achievement among parents was related to non-completion. Higher levels of emotional reactions to their child's trauma and greater perceived social support were related to non-response.Conclusions: The children seemed to profit from the parent-led Step One despite their parents` mental health challenges, stress, and practical barriers. The association between greater perceived social support and non-response was unexpected and warrants further investigation. To further increase treatment completion and response rates among children, parents with lower education may need more assistance on how to perform the interventions, while parents who are very upset about their child's trauma may need more emotional support and assurance from the therapist.Trial registration: ClinicalTrials.gov NCT04073862; https://clinicaltrials.gov/ct2/show/NCT04073862. Retrospectively registered 03 June 2019 (first patient recruited May 2019).

The children seemed to profit from Step One despite parents' mental health challenges and practical barriers.Response may improve if parents' emotional reactions to a child's trauma is addressed.Parents with lower education may need more assistance in performing Step One.

CONCLUSION: Patients with HFimpEF seem to have a better mid-term prognosis in terms of reduced mortality and hospital admissions. This improvement could be conditioned by the clinical profile of patients HFimpEF.

Factores predictores de resultado en tratamiento de tabaquismo en población de adultos mayores de la Comunidad Valenciana / Predictors of smoking treatment outcome in a population of older adults in the Valencian Community

El consumo de tabaco es uno de los más importantes factores de riesgo de enfermedad y muerte en España. Por ello, el objetivo de este estudio fue investigar las características epidemiológicas de 239pacientes fumadores mayores de 50 años en una unidad hospitalaria de deshabituación de tabaco, así como analizar los principales factores predictores que pueden influir en sus intentos de cese a losdoce meses. Es un estudio analítico transversal con tratamiento multicomponente combinando terapia psicológica e intervención farmacológica. Para comparar el éxito de abandono de los pacientes yconocer los posibles factores predictores, se llevó a cabo un análisis multivariante y de regresión logística binaria. De todos los pacientes, el 49,7% estableció el día D y la tasa de abandono final fue de 41,4%. Los predictores de intentos de abandono significativos fueron: índice paquetes-año entre 30 y 60, valor de cooximetría ≤ 10ppm, con una o más veces de intentos previos, tiempo máximo de cese superior a tres meses y grado alto en el test de Richmond. La escala de Minnesota con un valor inferior a 5 puntos fue el único predictor de abstinencia puntual a los doce meses. Los pacientes que consumieron menos tabaco y manifestaron intentos previos y alto grado de motivación tuvieron mayor posibilidad de tomar la decisión con éxito para dejar de fumar. Además, controlar el síndrome de abstinencia fue el aspecto más importante para tratar y reducir la tasa de recaída. (AU)

Tobacco consumption is one of the most important risk factors for disease and death in Spain. Therefore, the aim of this study was to investigate the epidemiological characteristics of 239 smoking patients over 50 years of age in a hospital smoking cessation unit, as well as to analyse the main predictors that may influence their cessation attempts at 12 months. It is a cross-sectional analytical study with multicomponent treatment combining psychological therapy and pharmacological intervention. A multivariate and binary logistic regression analysis was carried out to compare patients’ cessation success and to identify possible predictors. Of all patients, 49.7% established D-day and the final quit rate was 41.4%. Significant predictors of quit attempts were: pack-year index between 30 and 60, cooximetry value ≤ 10ppm, with one or more times of previous attempts, maximum cessation time greater than three months and high grade on the Richmond test. The Minnesota scale with a value of less than 5 points was the only predictor of timely abstinence at 12 months. Patients who used less tobacco and reported previous attempts and high motivation were more likely to make a successful decision to quit smoking. In addition, controlling the withdrawal syndrome was the most important aspect to treat and reduce the relapse rate. (AU)

Predictors and moderators of treatment outcomes in phase-based treatment and trauma-focused treatments in patients with childhood abuse-related post-traumatic stress disorder.

Background: Knowledge of treatment predictors and moderators is important for improving the effectiveness of treatment for PTSD due to childhood abuse.Objective: The first aim of this study was to test the potential predictive value of variables commonly associated with PTSD resulting from a history of repeated childhood abuse, in relation to treatment outcomes. The second aim was to examine if complex PTSD symptoms act as potential moderators between treatment conditions and outcomes.Method: Data were obtained from a randomized controlled trial comparing a phase-based treatment (Skills Training in Affect and Interpersonal Regulation [STAIR] followed by Eye Movement Desensitization and Reprocessing [EMDR] therapy; n = 57) with a direct trauma-focused treatment (EMDR therapy only; n = 64) in people with PTSD due to childhood abuse. The possible predictive effects of the presence of borderline personality disorder, dissociative symptoms, and suicidal and self-injurious behaviours were examined. In addition, it was determined whether symptoms of emotion regulation difficulties, self-esteem, and interpersonal problems moderated the relation between the treatment condition and PTSD post-treatment, corrected for pre-treatment PTSD severity.Results: Pre-treatment PTSD severity proved to be a significant predictor of less profitable PTSD treatment outcomes. The same was true for the severity of dissociative symptoms, but only post-treatment, and not when corrected for false positives. Complex PTSD symptoms did not moderate the relationship between the treatment conditions and PTSD treatment outcomes.Conclusions: The current findings suggest that regardless of the common comorbid symptoms studied, immediate trauma-focused treatment is a safe and effective option for individuals with childhood-related PTSD. However, individuals experiencing severe symptoms of PTSD may benefit from additional treatment sessions or the addition of other evidence-based PTSD treatment approaches. The predictive influence of dissociative sequelae needs further research.The study design was registered in The Dutch trial register (https://www.trialregister.nl/trialreg/admin/rctview.asp?TC = 5991) NTR5991 and was approved by the medical ethics committee of Twente NL 56641.044.16 CCMO.

One of first studies that aimed to identify multiple potential predictors and moderators in patients with PTSD related to childhood abuse.Only severe PTSD predicted worse treatment outcomes.The predictive influence of dissociative sequelae needs further research.

Objective: To evaluate the relationship between the pattern of ST-segment elevation in aVR and nonlethal cardiovascular complications. Methods: Observational cross-sectional study, with analytical component of all patients admitted with non-ST-segment elevation acute coronary syndrome at the Manuel Fajardo University Hospital of Havana between 2016 and 2020. Results: Female gender predominated in the first group, with an average age of 78 years. There was incidence of ischemic heart disease (75 percent and 56.4 percent) and arterial hypertension (78.8 percent and 85.8 percent). A significant statistical relationship was determined between the pattern with ST-segment elevation in aVR and cardiovascular complications with a relative risk of 5.769 times. Conclusions: ST-segment suprathreshold pattern in non-ST-segment elevation acute coronary syndrome predicts non-lethal in-hospital cardiovascular complications(AU)

Complicaciones quirúrgicas infecciosas en adultos mayores tras cirugía abdominal de urgencia

Introducción: En la actualidad el aumento de la población envejecida, asociado al desarrollo de la anestesiología, la cirugía y los cuidados intensivos ha generado un incremento del número de adultos mayores con abdomen agudo, que requieren tratamiento quirúrgico con urgencia, no exentos de complicaciones. Se realizó una revisión en bases de datos bibliográficas y se seleccionaron 25 documentos en idioma inglés y español. Objetivo: Analizar las características esenciales que identifican a los pacientes adultos mayores con complicaciones quirúrgicas infecciosas tras cirugía abdominal de urgencia. Desarrollo: En el plano biológico suceden cambios por reducción de la reserva fisiológica del adulto mayor: respiratorios, cardiovasculares, genitourinarios, digestivos, endocrino-metabólicos y del equilibrio ácido-base, que los hacen vulnerables al estrés quirúrgico. Las complicaciones posoperatorias constituyen un importante indicador de calidad: retardan la evolución de la enfermedad, prolongan la estadía hospitalaria e incrementan los índices de morbilidad y mortalidad de modo significativo en enfermos de este grupo etario. Conclusiones: A pesar del aumento del número de adultos mayores con abdomen agudo que requieren tratamiento quirúrgico con urgencia, la edad no debe considerarse como una limitante para efectuar la operación. Además del tratamiento específico y preventivo de las complicaciones tras cirugía abdominal de urgencia, las comorbilidades y la fragilidad presentes en estos pacientes requieren adecuada compensación preoperatoria, operatoria y posoperatoria, a fin de garantizar la evolución satisfactoria de estos enfermos.

Introduction: Currently, the increase in the aging population associated with the development of anesthesiology, surgery and intensive care has generated an increase in the number of older adults with acute abdomen requiring urgent surgical treatment. A review was carried out in bibliographic databases, and 25 documents were selected in English and Spanish. Objective: To analyze the clinical, epidemiological and therapeutic characteristics that identify older adult patients with infectious surgical complications after emergency abdominal surgery. Development: At the biological level, changes occur due to the reduction of the physiological reserve of the elderly: respiratory, cardiovascular, genitourinary, digestive, endocrine-metabolic and acid-base balance that makes them vulnerable to surgical stress. Postoperative complications are an important indicator of quality: they delay the evolution of the disease, prolong hospital stay and significantly increase morbidity and mortality rates in patients of this age group. Conclusions: Despite the increase in the number of older adults with acute abdomen who require urgent surgical treatment, age should not be considered as a limitation to perform the operation. In addition to the specific and preventive treatment of complications after emergency abdominal surgery, the comorbidities and frailty present in these patients require adequate preoperative, operative and postoperative compensation, in order to guarantee the satisfactory evolution of these patients.

Predictive factors for inadequate bowel cleansing in colon capsule endoscopy / Factores predictores de limpieza colónica inadecuada en exploraciones con cápsula endoscópica de colon

Background and aims: Achieving adequate bowel cleansing is of utmost importance for the efficiency of colon capsule endoscopy (CCE). However, information about predictive factors is lacking. The aim of this study was to assess the predictive factors of poor bowel cleansing in the CCE setting. Methods: In this observational study, 126 patients who underwent CCE at two tertiary care hospitals were included between June 2017 and January 2020. Participants prepared for bowel cleansing with a 1-day clear liquid diet, a 4-L split-dose polyethylene glycol regimen and boosters with sodium phosphate, sodium amidotrizoate and meglumine amidotrizoate. Domperidone tablets and bisacodyl suppositories were administered when needed. Overall and per-segment bowel cleansing was evaluated using a CCE cleansing score. Simple and multiple logistic regression analysis were carried out to assess poor bowel cleansing and excretion rate predictors. Results: Overall bowel cleansing was optimal in 53 patients (50.5%). Optimal per-segment bowel cleansing was achieved as follows: cecum (86 patients; 74.8%), transverse colon (91 patients; 81.3%), distal colon (81 patients; 75%) and rectum (64 patients; 66.7%). In the univariate analysis, elderly (OR, 1.03; 95% CI (1.01–1.076)) and constipation (OR, 3.82; 95% CI (1.50–9.71)) were associated with poor bowel cleansing. In the logistic regression analysis, constipation (OR, 3.77; 95% CI (1.43–10.0)) was associated with poor bowel cleansing. No variables were significantly associated with the CCE device excretion rate. Conclusion: Our results suggest that constipation is the most powerful predictor of poor bowel cleansing in the CCE setting. Tailored cleansing protocols should be recommended for these patients.(AU)

Antecedentes y objetivos Lograr una limpieza intestinal adecuada es de gran importancia para la eficiencia de la cápsula endoscópica de colon (CEC). Se carece de información sobre factores predictivos. El objetivo fue evaluar los factores predictivos de la limpieza colónica deficiente en pacientes con CEC. Métodos: Ciento veintiséis pacientes fueron sometidos a CEC en dos hospitales de tercer nivel entre junio de 2017 y enero de 2020. La preparación consistió en un día de dieta líquida, y 4 l de polietilenglicol (dosis fraccionada), fosfato sódico, amidotrizoato de sodio y meglumina amidotrizoato. Ocasionalmente se administró domperidona y supositorios de bisacodilo. Se evaluó limpieza total y por segmentos. Se realizó un análisis de regresión logística simple y múltiple para evaluar factores de limpieza deficiente y de excreción de la CEC. Resultados: La limpieza intestinal fue óptima en 53 pacientes (50,5%). Por segmentos fue: ciego y ascendente (86 pacientes; 74,8%), transverso (91 pacientes; 81,3%), distal (81 pacientes; el 75%) y recto (64 pacientes; 66,7%). En la regresión simple, la edad avanzada (OR, 1,03, IC 95% [1,01-1,076]) y el estreñimiento (OR, 3,82; IC 95% [1,50-9,71]) se asociaron con una limpieza deficiente. El estreñimiento (OR, 3,77; IC del 95% [1,43-10,0]) fue el único factor asociado de forma independiente. Ninguna variable se asoció a la tasa de excreción de la CEC. Conclusión: Nuestros resultados sugieren que el estreñimiento es el factor más potente de la limpieza deficiente colónica en el estudio endoscópico con CEC. Protocolos de limpieza adaptados se deben recomendar en estos pacientes.(AU)

Machine learning approaches to identify profiles and predictors of psychosocial discomfort among Italian college students / Enfoques de machine learning para identificar perfiles y predictores de malestar psicosocial entre estudiantes universitarios italianos

Abstract Introduction College students live a crucial period of transition from late adolescence to adulthood when they have to deal with important stressful tasks. Thus, university often represents a stressful environment, pushing students to cope with a high academic pressure. As a result, this period constitutes a sensitive age for the onset of mental disorders. Typically, students are not aware of the early signs of their own compromised mental health until symptoms aggravate to an overt disorder. Therefore, it is important to timely detect subthreshold symptoms mostly related to generic mental distress. Objective First, to assess psychophysical well-being and mental distress among college students in northern Italy, and to detect predictors, among socio-demographic and academic characteristics, and risky drug use of these two outcomes. Method The study involved 13,886 students who received an email explaining the purpose of the e-research. The questionnaires used were the General Health Questionnaire (GHQ-12), the University Stress Scale (USS), and a modified version of World Health Organization-ASSIST v3.0. Results 3,754 students completed the web-survey. Students showed poor well-being and mental distress. The strongest predictor of mental distress and compromised well-being was physical health, followed by sex, study field, risky drug use, and academic performance concerns. Discussion and conclusion This study shows that it is very important to promote in college students healthy behaviors in order to increase their physical exercise and reduce substance use. Moreover, it would be desirable to improve academic counselling facilities as an important front-line service to intercept mental health issues among young adults.

Resumen Introducción Los estudiantes universitarios pasan por un periodo crucial en su transición de la adolescencia tardía a la edad adulta, periodo en que tienen que lidiar con tareas estresantes. La universidad representa un entorno estresante, que empuja a los estudiantes a hacer frente a una alta presión académica. Como resultado, este periodo constituye una edad sensible para la aparición de trastornos mentales. En general, los estudiantes no cobran consciencia de los primeros signos de que su propia salud mental está en riesgo sino hasta que los síntomas se agravan y se convierten en un trastorno manifiesto. Por tanto, es importante detectar oportunamente los síntomas subumbrales relacionados ante todo con la angustia mental genérica. Objetivo Evaluar el bienestar psicofísico y la angustia mental entre estudiantes universitarios del norte de Italia, y en segundo lugar, detectar predictores entre las características sociodemográficas y académicas, y el uso de drogas de estos dos resultados. Método En el estudio participaron 13,886 estudiantes que recibieron un correo electrónico que explicaba el propósito de la investigación. Los instrumentos utilizados fueron el Cuestionario de Salud General (GHQ-12), la Escala de Estrés Universitario (USS) y una versión modificada de la Organización Mundial de la Salud-ASSIST v3.0. Resultados 3,754 estudiantes completaron la encuesta en línea. Los estudiantes mostraron bienestar y angustia mental. El predictor más fuerte de angustia mental y bienestar comprometido fue la salud física, seguido del sexo, el campo de estudio, el uso de drogas y el rendimiento académico. Discusión y conclusión Este estudio muestra que es muy importante promover entre los estudiantes universitarios comportamientos saludables para promover el ejercicio físico y reducir el consumo de sustancias. Además, sería deseable mejorar la orientación académica que es un importante servicio de primera línea para interceptar los problemas de salud mental en los estudiantes.

General empathy and medical empathy in Mexican medical students: Integration of an empathic profile.

OBJECTIVE: To identify the association between general empathy and medical empathy. Detect predictors of the level of medical empathy from general empathy. To determine the psychosocial profile that describes the relationship between general empathy, medical empathy, and demographic and academic characteristics in medical students. METHOD: Descriptive cross-sectional design. Medical students completed the Interpersonal Reactivity Index (IRI) and the Jefferson Scale of Physician Empathy-student version (JSPE-S). RESULTS: Relatively high levels of general and medical empathy were detected. The total score of the IRI and the JSPE-S and their dimensions correlated positively (r = 0.14-0.52), except for the dimension personal distress of the IRI. The score of the IRI dimension empathic concern was the best predictor of the JSPE-S score and its dimensions (b = 0.27-0.54). Four profiles were detected: 1) men, preference for technology-oriented specialty, less empathy; 2) pre-clinical period students, less empathy; 3) students of the clinical period, greater empathy; and 4) women, preference for patient-oriented specialty, greater empathy. CONCLUSIONS: General and medical empathy are associated. Differentiated empathic profiles will allow the design of instructional strategies in empathy according to the specific needs of each one.

OBJETIVO: Identificar la asociación entre empatía general y empatía médica. Detectar predictores del nivel de empatía médica a partir de la empatía general. Determinar el perfil psicosocial que describa la relación entre empatía general, empatía médica y características demográficas y académicas en estudiantes de medicina. MÉTODO: Estudio transversal descriptivo. Estudiantes de medicina completaron el Índice de Reactividad Interpersonal (IRI) y la Escala de Empatía Médica de Jefferson versión estudiantil (EEMJ-E). RESULTADOS: Se detectaron niveles relativamente altos de empatía general y médica. El puntaje total del IRI y la EEMJ-E y sus dimensiones se correlacionaron positivamente (r = 0.14-0.52), excepto para la dimensión malestar personal del IRI. El puntaje en la dimensión preocupación empática del IRI fue el mejor predictor del puntaje de la EEMJ-E y sus dimensiones (b = 0.27-0.54). Se detectaron cuatro perfiles: 1) hombres, preferencia por especialidad orientada a la tecnología, menor empatía; 2) estudiantes del periodo preclínico, menor empatía; 3) estudiantes del periodo clínico, mayor empatía; y 4) mujeres, preferencia por especialidad orientada al paciente, mayor empatía. CONCLUSIONES: La empatía general y la empatía médica se encuentran asociadas. Unos perfiles empáticos diferenciados permitirán el diseño de estrategias de instrucción en empatía acordes con las necesidades específicas de cada uno.

Predictores de mortalidad en pacientes con exacerbación de enfermedad pulmonar obstructiva crónica / Mortality predictors in patients with exacerbation of chronic obstructive pulmonary disease

RESUMEN Fundamento: La enfermedad pulmonar obstructiva crónica (EPOC) es un problema de salud y constituye la tercera causa de defunción en el mundo. La mortalidad es mayor en los pacientes que presentan exacerbaciones de esa enfermedad. Objetivo: Determinar los factores predictores de mortalidad en pacientes hospitalizados con exacerbación de EPOC en una institución hospitalaria del segundo nivel de atención en Cuba. Metodología: Se realizó un estudio transversal en el Hospital General Provincial Camilo Cienfuegos de Sancti Spíritus, durante dos años. Se incluyeron 335 pacientes. Las variables recogidas se agruparon en sociodemográficas, clínicas, enfermedades crónicas asociadas y estado del paciente al egreso. Se elaboró un árbol de decisión mediante el método Chaid exhaustivo, la variable dependiente fue la mortalidad por EPOC. Resultados: Predominaron los pacientes del sexo femenino (55.2 %), con 60 años o más (79 %) y con más de 4 exacerbaciones en el último año (53.1 %). El modelo del árbol de decisión tuvo una sensibilidad de 97 %, especificidad de 89.3 % y un porcentaje global de pronóstico correcto del 93.1 %. Se identificaron seis variables predictores de mortalidad: insuficiencia respiratoria aguda, diagnóstico de neumonía, no utilización de antitrombóticos, tromboembolismo pulmonar, edad mayor de 60 años y el hábito de fumar. Conclusiones: La probabilidad más alta de fallecer durante una exacerbación de EPOC se da entre los pacientes con insuficiencia respiratoria aguda, los que son diagnosticados con neumonía durante el ingreso, los que no realizan tratamiento antitrombótico y los que tienen más de 60 años de edad.

ABSTRACT Background: Chronic obstructive pulmonary disease (COPD) is a health problem and the third cause of death in the world. Mortality is higher in patients who present exacerbations of this disease. Objective: To determine mortality predictors in hospitalized patients with exacerbation of COPD in a second care level hospital in Cuba. Methodology: A cross-sectional study was conducted at Camilo Cienfuegos Provincial General Hospital in Sancti Spíritus, for two years. 335 patients were included. The variables collected were grouped into sociodemographic, clinical, associated chronic diseases and patient status at discharge. A decision tree was developed using the exhaustive Chaid method, the dependent variable was mortality from COPD. Results: Female patients (55.2 %), 60 years or older (79 %) and with more than 4 exacerbations in the last year (53.1 %) predominated. The decision tree model had a sensitivity of 97 %, a specificity of 89.3 %, and an overall percentage of correct diagnosis of 93.1 %. Six variables that predicted mortality were identified: acute respiratory failure, diagnosis of pneumonia, non-use of antithrombotics, pulmonary thromboembolism, age over 60 years, and smoking. Conclusions: The highest probability of dying during an exacerbation of COPD occurs among patients with acute respiratory failure, those who are diagnosed with pneumonia during admission, those who do not receive antithrombotic treatment and those who are over 60 years of age.
