[Translated article] Determining factors on length of stay in primary total knee arthroplasty patients using enhanced recovery protocol after surgery (ERAS) pathway.

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 ASA II. 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 haemoglobin level at 48-72h (p<.001), the time of first postoperative mobilisation 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 optimise the quality of care and available health resources.

Predictors of adherence to follow-up and treatment success in childhood obesity.

INTRODUCTION: Management of childhood obesity, based upon behavioural, physical activity and dietary guidance, usually achieves limited success and is hindered by a high attrition rate. The identification of potential predictors of either weight loss or early weight management attrition could help develop personalised management plans in order to improve patient outcomes. PATIENTS AND METHODS: We conducted a retrospective study in a cohort of 1300 patients with obesity managed in speciality clinics for up to 5 years with outpatient conservative treatment. We studied the family background and personal characteristics (demographic, behavioural, psychosocial, anthropometric and metabolic) of patients who dropped out before completing the first year of the programme and patients who achieved significant weight loss, with a separate analysis of patients who achieved substantial reductions in weight compared to the rest of the cohort. RESULTS: The mean age of the patients in the cohort was 10.46 years (SD, 3.48) the mean BMI z-score 4.01 (SD, 1.49); 52.8% of the patients were male, 53.3% were prepubertal, 75.8% were Caucasian and 19% Latin. We found a higher proportion of Latinla ethnicity and compulsive eating in the group of patients with early attrition from the weight management follow-up. In the group of patients with substantial weight loss, a greater proportion were male, there was a higher frequency of dietary intake control at home and obesity was more severe, and the latter factor was consistently observed in patients who achieved substantial weight loss at any point of the follow-up. CONCLUSIONS: Some family and personal characteristics in childhood obesity are associated with an increased risk of early withdrawal from follow-up or a greater probability of successful outcomes; however, the predictive value of these variables is limited.

[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.

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.

Predictors of effusion viscosity in otitis media with effusion: neutrophil lymphocyte ratio versus mean platelet volume.

OBJETIVOS: comparar entre el índice de neutrófilos linfocitos (NLR) y el volumen plaquetario medio (VPM) en la predicción de la viscosidad del derrame en la otitis media con derrame. MATERIALES Y MéTODOS: Se incluyeron en el estudio 248 niños con derrame en el oído medio. Se evaluaron los hemogramas completos (CBC) preoperatorios. Se registraron los valores de NLR y MPV. La viscosidad del derrame se evaluó durante la cirugía mientras se aspiraba el derrame después de la miringotomía. Se clasificaron 2 tipos de derrames; tipos serosos y mucoides. RESULTADOS: se reportaron diferencias estadísticamente significativas en NLR y MPV entre los derrames serosos y mucoides. Los valores de corte de NLR y MPV para diferenciar entre derrames serosos y mucoides fueron 1,21 y 7,95 respectivamente. Cuando se compararon NLR y MPV, NLR pareció tener mayor sensibilidad, especificidad y precisión diagnóstica que MPV. CONCLUSIóN: NLR es superior a MPV como predictor de la viscosidad del derrame en otitis media con derrame. Ambos marcadores se consideran rentables y fiables para la evaluación de la viscosidad del derrame.

Predictors of mechanical ventilation and mortality in critically ill patients with COVID-19 pneumonia.

OBJECTIVE: To determine if potential predictors for invasive mechanical ventilation (IMV) are also determinants for mortality in COVID-19-associated acute respiratory distress syndrome (C-ARDS). DESIGN: Single center highly detailed longitudinal observational study. SETTING: Tertiary hospital ICU: two first COVID-19 pandemic waves, Madrid, Spain. PATIENTS OR PARTICIPANTS: 280 patients with C-ARDS, not requiring IMV on admission. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Target: endotracheal intubation and IMV, mortality. PREDICTORS: demographics, hourly evolution of oxygenation, clinical data, and laboratory results. RESULTS: The time between symptom onset and ICU admission, the APACHE II score, the ROX index, and procalcitonin levels in blood were potential predictors related to both IMV and mortality. The ROX index was the most significant predictor associated with IMV, while APACHE II, LDH, and DaysSympICU were the most with mortality. CONCLUSIONS: According to the results of the analysis, there are significant predictors linked with IMV and mortality in C-ARDS patients, including the time between symptom onset and ICU admission, the severity of the COVID-19 waves, and several clinical and laboratory measures. These findings may help clinicians to better identify patients at risk for IMV and mortality and improve their management.

Las apolipoproteínas como marcadores predictivos de riesgo metabólico-vascular en pediatría / Apolipoproteins as predictive markers of metabolic-vascular risk in pediatrics

Introducción: La búsqueda de nuevos marcadores predictivos, en la estratificación de riesgos metabólicos-vasculares, es de vital importancia en la prevención, diagnóstico y tratamiento oportuno de enfermedades cardiometabólicas, al considerar que el proceso aterosclerótico se inicia desde la infancia. La revisión documental se realizó entre marzo y julio del 2022, consultadas las bases de datos PubMed/Medline, SciElo, Scopus y el Google académico como puerta de entrada de la información sobre el tema. Se revisaron 33 artículos originales en el período 2012-2021 en idioma inglés y español, referenciados 29 y los términos clave para la búsqueda fueron, riesgo metabólico-vascular, apolipoproteínas A1 y B100, marcadores predictores de riesgo metabólico-vascular, niñez, adolescencia. Objetivo: Analizar la importancia de las apolipoproteínas como marcadores predictores del riesgo metabólico- vascular pediátrico. Desarrollo: Las apolipoproteínas han surgido como una alternativa muy viable, particularmente la determinación de ApoB 100 y ApoA 1, que expresan el equilibrio entre la actividad aterogénica y la antiaterogénica y están presentes desde las edades tempranas de la vida. El diagnóstico temprano de estos marcadores, permitirá aplicar intervenciones precoces para propiciar cambios a estilos de vidas saludables, así como tratamientos preventivos que impidan las complicaciones de la enfermedad cardiometabólica. Conclusiones: Al considerar que el proceso aterosclerótico se inicia en edades tempranas, las apolipoproteínas constituyen marcadores en la predicción del riesgo metabólico-vascular, su determinación permite la identificación, estratificación del riesgo y propuesta de estrategias preventivas desde las edades pediátricas(AU)

Introduction: The search for new predictive markers, in the stratification of metabolic-vascular risks, is of vital importance in the prevention, diagnosis and timely treatment of cardiometabolic diseases, considering that the atherosclerotic process begins in childhood. The documentary review was carried out between March and July 2022, consulting the PubMed/Medline, SciElo, Scopus and Google Scholar databases as a gateway to information on the topic. 33 original articles were reviewed in the period 2012-2021 in English and Spanish, 29 were referenced and the key terms for the search were, metabolic-vascular risk, apolipoproteins A1 and B100, markers predictive of metabolic-vascular risk, childhood adolescence. Objective: To analyze the importance of apolipoproteins as predictive markers of pediatric metabolic-vascular risk. Development: Apolipoproteins have emerged as a very viable alternative, particularly the determination of ApoB 100 and ApoA 1, which express the balance between atherogenic and antiatherogenic activity and are present from the early ages of life. Early diagnosis of these markers will allow for early interventions to promote changes to healthy lifestyles, as well as preventive treatments that prevent complications of cardiometabolic disease. Conclusions: Considering that the atherosclerotic process begins at an early age, apolipoproteins constitute markers in the prediction of metabolic-vascular risk, their determination allows the identification, risk stratification and proposal of preventive strategies from pediatric ages(AU)

Development and validation of a prognostic nomogram for the renal relapse of lupus nephritis.

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.

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.

Improvement of left ventricular ejection fraction in patients with heart failure with reduced ejection fraction: Predictors and clinical impact.

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.

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.

Relación del supradesnivel del segmento ST en aVR con las complicaciones cardiovasculares / Relationship of ST-segment elevation in AVR to cardiovascular complications

Introducción: El patrón de supradesnivel del segmento ST en aVR en el síndrome coronario agudo se asocia con un aumento de la mortalidad. Objetivo: Evaluar la relación entre el patrón de supradesnivel del segmento ST en aVR y las complicaciones cardiovasculares no letales. Método: Estudio observacional de corte transversal, con componente analítico de todos los pacientes ingresados con síndrome coronario agudo sin elevación del segmento ST, en el Hospital Universitario Manuel Fajardo de la Habana entre los años 2016 y 2020. Resultados: Predominó el sexo femenino en el primer grupo, con una mediana de 78 años. Hubo incidencia de cardiopatía isquémica (75 por ciento y 56,4 por ciento) e hipertensión arterial (78,8 por ciento y 85,8 por ciento ). Se determinó una relación estadística significativa entre el patrón con elevación del segmento ST en aVR y las complicaciones cardiovasculares con un riesgo relativo de 5,769 veces. Conclusiones: El patrón de supradesnivel del segmento ST en un síndrome coronario agudo sin elevación del segmento ST predice complicaciones intrahospitalarias cardiovasculares no letales(AU)

Introduction: The pattern of ST-segment elevation in aVR in acute coronary syndrome is associated with increased mortality. 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.

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.
