RESUMO
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.

INTRODUCTION: Medical students report higher levels of anxiety than students from other majors. Knowledge about their psychological well-being is scarce. OBJECTIVE: To identify sociodemographic and academic factors that predict the level of anxiety and psychological well-being in Mexican medical students. METHOD: Cross-sectional study of Mexican medical students of first (n = 59), third (n = 43) and fifth semester (n = 59), who answered a sociodemographic questionnaire, Beck Anxiety Inventory, the Psychological Well-being Scale for adults and the Family Adaptability and Cohesion Evaluation Scale. RESULTS: Females showed higher levels of anxiety (p < 0.01). Anxiety in males was similar in the different semesters (p > 0.05); women of third and fifth semesters were more anxious than those at first semester (p < 0.01). Anxiety and psychological well-being were negatively correlated (p < 0.001). The "Less anxiety, higher level of well-being" and "More anxiety, lower level of well-being" subgroups were characterized, and a logistic regression identified that being a woman (OR = 4.70) and not practicing any religion (OR = 2.49) are predictive factors of higher levels of anxiety. CONCLUSIONS: Female medical students constitute a population at risk for higher levels of anxiety and less psychological well-being, which compromises their learning, quality of life and future professional practice.
INTRODUCCIÓN: Estudiantes de medicina reportan mayor ansiedad que estudiantes de otras carreras. El conocimiento sobre su bienestar psicológico es escaso. OBJETIVO: Identificar factores sociodemográficos y académicos predictores del nivel de ansiedad y bienestar psicológico en estudiantes mexicanos de medicina. MÉTODO: Estudio transversal de estudiantes mexicanos de medicina de primer (n = 59), tercer (n = 43) y quinto semestre (n = 59), que contestaron un cuestionario sociodemográfico, la Escala de Ansiedad de Beck, la Escala de Bienestar Psicológico para Adultos y la Escala de Evaluación de la Cohesión y la Adaptabilidad Familiar. RESULTADOS: Las mujeres presentaron mayor ansiedad (p < 0.01). La ansiedad en hombres fue similar en los distintos semestres (p > 0.05); las mujeres de tercer y quinto semestre fueron más ansiosas que las del primero (p < 0.01). Ansiedad y bienestar psicológico correlacionaron negativamente (p < 0.001). Se identificaron los subgrupos "Menor ansiedad, mayor bienestar" y "Mayor ansiedad, menor bienestar", y una regresión logística identificó que ser mujer (OR = 4.70) y no profesar alguna religión (OR = 2.49) son factores predictores de mayor ansiedad. CONCLUSIONES: Las estudiantes de medicina constituyen una población de riesgo para mayor ansiedad y menor bienestar psicológico, lo que compromete su aprendizaje, calidad de vida y futuro ejercicio profesional.

Colonoscopy is the gold standard procedure for detecting neoplastic lesions of the colon and its efficiency is closely linked to the quality of the procedure. Adequate bowel preparation is a crucial factor in achieving the recommended quality indicators, but poor preparation has been reported in up to 30% of outpatients referred for colonoscopy. Consequently, over recent years, a number of studies have developed strategies to optimise bowel cleansing by improving adherence and tolerance to and the efficacy of the bowel preparation. Moreover, the identification of risk factors for inadequate bowel cleansing has led to tailored bowel preparation strategies being designed, with promising results. We aimed to review studies that assessed risk factors for inadequate bowel preparation and strategies to optimise bowel cleansing in patients at high risk of having poor preparation.

OBJECTIVE: To identify predictors of frequent attenders (HF) in Primary Health Care (PHC) centres in a sample of frequent attenders (HF) in Emergency Departments (ED). DESIGN: This was an observational, retrospective, multicentre cohort study. PARTICIPANTS: The HF patients were selected from patients seen in the ED between January 1 and December 31, 2013. Setting Patients were recruited from 17 public hospitals of the Community of Madrid, Spain. METHOD: Variables on the index visit to the ED were collected. The sample was analysed in terms of being or not being an HF user in PHC. An HF user is considered a patient who made at least 10 visits in each level of care for a year. RESULTS: A total of 1284 HF patients were included. An analysis was performed on 423 (32.9%) HF users in ED with 16 (12-25) visits to PHC vs. 861 (67.1%) non-HF users in ED, with 4 (2-6) visits to PHC. Independent predictors of HF in PHC: over 65 years (OR: 1.51; 95% CI: 1.07-2.13; P=.019), cognitive impairment (OR: 1.63; 95% CI: 1.01-2.65; P=.049), taking >3 drugs (OR: 1.56; 95% CI: 1.06-2.30; P=.025), and living in the community vs. nursing home or homeless (OR: 3.05; 95% CI: 1.14-8.16; P=.026). CONCLUSIONS: Among HF patients in the ED, the fact that of being over 65 years, taking 3or more drugs, suffering cognitive impairment, and living in the community, are also considered to be predictors of HF in PHC.

OBJECTIVE: To determine the relationship between QRS duration and dispersion and the occurrence of ventricular arrhythmias in early stages of acute myocardial infarction (AMI). DESIGN: A retrospective, longitudinal descriptive study was carried out. SETTING: Hospital General Universitario "Camilo Cienfuegos", Sancti Spíritus, Cuba. Secondary health care. PATIENTS OR PARTICIPANTS: A total of 209 patients diagnosed with ST-segment elevation AMI from January 2012 to June 2014. MAIN VARIABLES OF INTEREST: The duration and dispersion of the QT interval, corrected QT interval, and QRS complex were measured in the first electrocardiogram performed at the hospital. The presence of ventricular tachycardia/fibrillation was assessed during follow-up (length of hospital stay). RESULTS: Arrhythmias were found in 46 patients (22%); in 25 of them (15.9%), arrhythmias originated in ventricles, and were more common in those subjects with extensive anterior wall AMI, which was responsible for 81.8% of the ventricular fibrillations and more than half (57.1%) of the ventricular tachycardias. The widest QRS complexes (77.3±13.3 vs. 71.5±6.4ms; P=.029) and their greatest dispersion (24.1±16.2 vs. 16.5±4.8ms; P=.019) were found on those leads that explore the regions affected by ischemia. The highest values of all measurements were found in extensive anterior wall AMI, with significant differences: QRS 92.3±18.8ms, QRS dispersion 37.9±23.9ms, corrected QT 518.5±72.2ms, and corrected QT interval dispersion 94.9±26.8ms. Patients with higher QRS dispersion values were more likely to have ventricular arrhythmias, with cutoff points at 23.5ms and 24.5ms for tachycardia and ventricular fibrillation, respectively. CONCLUSIONS: Increased QRS duration and dispersion implied a greater likelihood of ventricular arrhythmias in early stages of AMI than increased duration and dispersion of the corrected QT interval.

INTRODUCTION: Laparoscopic cholecystectomy (LC) performed as day-case (DC) surgery has more unexpected admissions than most day-case procedures. We revised the literature about factors associated with unexpected admissions in LC as well as reconversion to open laparotomy and we investigate these factors in our series. METHODS: Retrospective cohort study, period 1999-2013 (511 cases). We study factors that in the literature have been associated with unpredicted admissions in DC or reconversion. RESULTS: In the period 1999-2013 511 patients were included (166 male/345 female), median age 53 years. Surgical indication was: Symptomatic cholelithiasis (386 cases), previous episode of cholecystitis (52 cases), biliary pancreatitis (47 cases) and ERCP for common duct stones (11 cases). 70% were discharged on the same day, 13% overnight and 17% stayed longer than 24 hours. Reconversion rate was 3.3%, readmission rate 2.8% and reoperation rate 1.2%. Bivariant study showed significant statistical association with age 65 or, ASA classification II or higher, previous admission for acute cholecystitis and logistic regression showed them to be significantly associated with readmission (sensibility: 10.6%, specificity: 98.6%, R2 coefficient: 0.046-0.066). CONCLUSIONS: The model's predictive capacity is null. We think that factors other than indications are responsible for the high proportion of failure showed by LC in DC.

AIMS: Fournier's gangrene (FG) is the necrotizing fasciitis of the perineum and genital area and presents a high mortality rate. The aim was to assess prognostic factors for mortality, create a new mortality predictive scale and compare it with previously published scales in patients diagnosed with FG in our Emergency Department. METHODS: Retrospective analysis study between 1998 and 2012. RESULTS: Of the 59 patients, 44 survived (74%) (S) and 15 died (26%) (D). Significant differences were found in peripheral vasculopathy (S 5 [11%]; D 6 [40%]; P=.023), hemoglobin (S 13; D 11; P=.014), hematocrit (S 37; D 31.4; P=.009), white blood cells (S 17,400; D 23,800; P=.023), serum urea (S 58; D 102; P<.001), creatinine (S 1.1; D 1.9; P=.032), potassium (S 3.7; D 4.4; P=.012) and alkaline phosphatase (S 92; D 133; P=.014). Predictive scores: Charlson index (S 1; D 4; P=.013), severe sepsis criteria (S 16 [36%]; D 13 [86%]; P=.001), Fournier's gangrene severity index score (FGSIS) (S 4; D 7; P=.002) and Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; D 13; P=.004). Independent predictive factors were peripheral vasculopathy, serum potassium and severe sepsis criteria, and a model was created with an area under the ROC curve of 0.850 (0.760-0.973), higher than FGSIS (0.746 [0.601-0.981]) and UFGSI (0.760 [0.617-0.904]). CONCLUSIONS: FG showed a high mortality rate. Independent predictive factors were peripheral vasculopathy, potassium and severe sepsis criteria creating a predictive model that performed better than those previously described.

BACKGROUND: Gastroesophageal varices are present in approximately 50% of patients with liver cirrhosis. The aim of this study was to evaluate liver stiffness measurement (LSM), Fib-4, Forns Index and Lok Score as noninvasive predictors of esophageal varices (EV). METHODS: This prospective study included 65 patients with HCV-related liver cirrhosis. All patients underwent routine laboratory tests, transient elastograhy (TE) and esophagogastroduodenoscopy. FIB-4, Forns Index and Lok Score were calculated. The diagnostic performances of these methods were assessed using sensitivity, specificity, positive predictive value, negative predictive value, accuracy and receiver operating characteristic curves. RESULTS: All predictors (LSM, FIB-4, Forns Index and Lok Score) demonstrated statistically significant correlation with the presence and the grade of EV. TE could diagnose EV at a cutoff value of 18.2kPa. Fib-4, Forns Index, and Lok Score could diagnose EV at cutoff values of 2.8, 6.61 and 0.63, respectively. For prediction of large varices (grade 2, 3), LSM showed the highest accuracy (80%) with a cutoff of 22.4kPa and AUROC of 0.801. Its sensitivity was 84%, specificity 72%, PPV 84% and NPV 72%. The diagnostic accuracies of FIB-4, Forns Index and Lok Score were 70%, 70% and76%, respectively, at cutoffs of 3.3, 6.9 and 0.7, respectively. For diagnosis of large esophageal varices, adding TE to each of the other diagnostic indices (serum fibrosis scores) increased their sensitivities with little decrease in their specificities. Moreover, this combination decreased the LR- in all tests. CONCLUSION: Noninvasive predictors can restrict endoscopic screening. This is very important as non invasiveness is now a major goal in hepatology.

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.

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.

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.
RESUMO
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.

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.

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.

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.

RESUMO
Conservative breast cancer surgery is facing a new problem: the potential tumour involvement of resection margins. This eventuality has been closely and negatively associated with disease-free survival. Various factors may influence the likelihood of margins being affected, mostly related to the characteristics of the tumour, patient or surgical technique. In the last decade, many studies have attempted to find predictive factors for margin involvement. However, it is currently the new techniques used in the study of margins and tumour localisation that are significantly reducing reoperations in conservative breast cancer surgery.

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.
RESUMO
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 56641.044.16â¯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.

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.
