Patterns of Physical Activity of Adolescents With ADHD in the School Context: A Cross-Sectional Study for Clinical Practice.

OBJECTIVES: To describe the daily Physical Activity (PA) patterns of adolescents with Attention-deficit/hyperactivity disorder (ADHD), to analyze the differences in terms of PA patterns between adolescents with ADHD and those without ADHD, and to study the factors associated with achieving the daily PA recommendations. METHODS: The sample was composed of 778 adolescents who provided complete information on their PA patterns through the Physical Activity Questionnaire for Adolescents (PAQ-A). Of these, 97 had ADHD according to DSM-5 criteria. RESULTS: The results show that being a girl or being of foreign origin and having ADHD have an impact on the achievement of the recommended amount of daily PA. CONCLUSIONS: When promoting PA in adolescents with ADHD within the school environment, it is necessary to consider different domains and specific contexts of a school day, paying special attention to girls and adolescents with ADHD of immigrant origin.

Sternal resection and reconstruction: a review.

Sternal resection and reconstruction is a rare but sometimes challenging procedure due to its profound anatomical and functional implications. For these reasons, an adequate preoperative evaluation is crucial in each patient, especially when we are faced with malignant lesions that sometimes require extensive radical resections, thus demanding an integrated reconstructive strategy that allows stabilizing the chest wall, protecting the underlying mediastinum and minimize resulting deformity. The large number of available reconstruction techniques and the lack of quality studies for their analysis mean that sternal reconstruction depends to a great extent on the consensus of experts or, more frequently, on the simple preference of each surgical team. This article aims to provide an overview of sternal resection and reconstruction. Indications for partial versus total or subtotal sternectomy are suggested and their surgical and oncological outcomes are presented. The use of rigid or semi-rigid prostheses is an ongoing debate, although recent functional data advise reserving rigid reconstructions for extensive defects. Sternectomy for primary tumors or local tumor involvement has a good prognosis with an overall survival of 5 and 10 years: 67% and 58%, respectively, provided that a radical resection with free surgical margins is performed. Breast cancer is the most common secondary sternal tumor, and surgery can offer 5-year overall survival ranging from 20% to 50% provided an R0 resection is achieved, although radical surgery does not appear to decrease rates. of recurrence. Metastases of origin other than the breast give the worst results (less than 40% at 36 months and 0% at 5 years) and although the data available on these cases are limited, the radicality of the resection does not seem to modify the survival or recurrence rates, so a conservative approach is probably more appropriate.

Operative outcomes and middle-term survival of robotic-assisted lung resection for clinical stage IA lung cancer compared with video-assisted thoracoscopic surgery / Resultados postoperatorios y de supervivencia a medio plazo de las resecciones pulmonares asistidas por robot en el cáncer de pulmón en estadio clínico IA en comparación con la cirugía toracoscópica videoasistida

Background: Despite limited published evidence, robotic-assisted thoracoscopic surgery (RATS) for anatomic lung resection in early-stage lung cancer continues growing. The aim of this study is to evaluate its safety and oncologic efficacy compared to video-assisted thoracoscopic surgery (VATS). Methods: Single-centre retrospective study of all patients with resected clinical stage IA NSCLC who underwent RATS or VATS anatomic lung resection from June 2018 to January 2022. RATS and VATS cases were matched by propensity scoring (PSM) according to age, sex, histology, and type of resection. Short-term outcomes were compared, and the Kaplan-Meier method and log-rank test were used to evaluate the overall survival (OS) and disease-free survival (DFS). Results: 321 patients (94 RATS and 227 VATS cases) were included. After PSM, 94 VATS and 94 RATS cases were compared. Demographics, pulmonary function, and comorbidity were similar in both groups. Overall postoperative morbidity was comparable for RATS and VATS cases (20.2% vs 25.5%, P = 0.385, respectively). Pathological nodal upstaging was similar in both groups (10.6% in RATS and 12.8% in VATS). During the 3.5-year follow-up period (median: 29 months; IQR: 18–39), recurrence rate was 6.4% in RATS group and 18.1% in the VATS group (P = 0.014). OS and DFS were similar in RATS and VATS groups (log rank P = 0.848 and P = 0.117, respectively). Conclusion: RATS can be performed safely in patients with early-stage NSCLC. For clinical stage IA disease, robotic anatomic lung resection offers better oncologic outcomes in terms of recurrence, although there are no differences in OS and DFS compared with VATS.(AU)

Introducción: A pesar de la limitada evidencia disponible, el uso de la RATS en resecciones pulmonares anatómicas por cáncer continúa creciendo. El objetivo de este estudio es evaluar su seguridad y eficacia oncológica en comparación con la VATS. Métodos: Estudio retrospectivo unicéntrico en el que se incluyeron todos los pacientes con CPNM en estadio cIA sometidos a resección pulmonar anatómica RATS o VATS entre junio de 2018 y enero de 2022. Los casos se emparejaron mediante puntuación de propensión (PSM) según edad, sexo, histología y tipo de resección. Se compararon los resultados a corto plazo y la supervivencia global (OS) y libre de enfermedad (DFS) mediante el método de Kaplan-Meier y la prueba de rangos logarítmicos. Resultados: Se incluyeron 321 pacientes (94 RATS y 227 VATS). Tras el PSM, se compararon 94 VATS y 94 RATS. La morbilidad global fue comparable en ambos grupos (20.2 % en RATS vs 25.5 % en VATS, P = 0.385). El upstaging ganglionar fue similar en ambos abordajes (10.6% en RATS y 12.8% en VATS). Durante los 3.5 años de seguimiento, la tasa de recurrencia fue del 6.4 % en RATS y del 18.1 % en VATS (P = 0.014). OS y DFS fueron similares en los dos grupos (rango logarítmico P = 0.848 y P = 0.117, respectivamente). Conclusión: La RATS se puede realizar de forma segura en pacientes con CPNM en estadio inicial. Para la enfermedad en estadio cIA, el abordaje robótico ofrece mejores resultados en términos de recurrencia, aunque no hay diferencias en la OS y la DFS en comparación con la VATS.(AU)

Risk factors of massive blood transfusion in liver transplantation: consequences and a new index for prediction including the donor / Factores de riesgo de transfusión masiva en trasplante hepático: consecuencias y creación de un nuevo índice teniendo en cuenta el tipo de donante

Background: Massive blood transfusion (MBT) is a common occurrence in liver transplant (LT) patients. Recipient-related risk factors include cirrhosis, history of multiple surgeries and suboptimal donors. Despite advances in surgical techniques, anesthetic management and graft preservation have decreased the need for transfusions, this complication has not been completely eliminated. Methods: One thousand four hundred and sixty-nine LT were performed at our institution between May 2003 and December 2020, and data was available regarding transfusion for 1198 of them. We divided the patients into two groups, with regards to transfusion of 6 or more units of packed red blood cells in the first 24 h posttransplant, and we analyzed the differences between the groups. Results: Out of the 1198 patients, 607 (50.7%) met criteria for MBT. Survival was statistically lower at 1, 3, and 5 years when comparing the groups that had MBT to those that did not (92.6%, 85.2% and 79.7%, respectively, in the non MBT group, vs. 78.1%, 71.6% y 66.8%, respectively, in the MBT group). MBT was associated with a 1.5 mortality risk as opposed to non-MBT patients. Logistical regression analysis of our variables yielded the following results for a new model, including serum creatinine (OR 1.97), sodium (OR 1.73), hemoglobin (OR 1.99), platelets (OR 1.37), INR (OR 1.4), uDCD (OR 2.13) and split liver donation. Conclusion: Massive blood transfusion impacts patient survival in a statistically significant way. The most significant risk factors are preoperative hemoglobin, INR and serum creatinine. (AU)

Introducción: La transfusión masiva de hemoderivados (TMH) es un hecho frecuente en el trasplante hepático (TH). A pesar de los avances en la técnica quirúrgica, manejo anestésico y preservación de órganos, la politransfusión no ha desaparecido. Métodos: 1469 TH fueron realizados en nuestro centro entre mayo de 2003 y diciembre de 2020, obteniéndose datos completos de trasfusión de 1198. Dividimos a los pacientes en dos grupos de acuerdo a la necesidad de trasfusión de 6 o más unidades de sangre en las primeras 24 horas después del trasplante, y analizamos las diferencias entre los grupos. Resultados: De los 1198 pacientes, 607 (50.7%) cumplieron criterios de TMH· La supervivencia fue estadísticamente inferior a 1, 3, y 5 años cuando comparamos los grupos en función de TMH o no (92·6%, 85·2% y 79·7%, respectivamente, en el no TMH, vs. 78·1%, 71·6% y 66·8%, respectivamente, en el grupo de TMH). Respecto al análisis de supervivencia, la TMH se asoció a un riesgo 1.5 veces mayor de mortalidad en contra de los pacientes sin TMH· El análisis de regresión logística nos permitió la creación de un nuevo modelo incluyendo creatinina sérica (OR 1.97), sodio (OR 1.73), hemoglobina (OR 1.99), plaquetas (OR 1.37), INR (OR 1.4), uDCD (OR 2.13) y trasplante procedente de split. Conclusión: La transfusión masiva de hemoderivados impacta en la supervivencia del paciente de forma estadísticamente significative. Los factores de riesgo preoperatorios más significativos han sido la hemoglobina, el INR y la creatinine. (AU)

Pressurized Liquid (PLE) Truffle Extracts Have Inhibitory Activity on Key Enzymes Related to Type 2 Diabetes (α-Glucosidase and α-Amylase).

An optimized PLE method was applied to several truffle species using three different solvent mixtures to obtain bioactive enriched fractions. The pressurized water extracts contained mainly (1 → 3),(1 → 6)-ß-D-glucans, chitins, and heteropolymers with galactose and mannose in their structures. The ethanol extracts included fatty acids and fungal sterols and others such as brassicasterol and stigmasterol, depending on the species. They also showed a different fatty acid lipid profile depending on the solvent utilized and species considered. Ethanol:water extracts showed interesting lipids and many phenolic compounds; however, no synergic extraction of compounds was noticed. Some of the truffle extracts were able to inhibit enzymes related to type 2 diabetes; pressurized water extracts mainly inhibited the α-amylase enzyme, while ethanolic extracts were more able to inhibit α-glucosidase. Tuber brumale var. moschatum and T. aestivum var. uncinatum extracts showed an IC50 of 29.22 mg/mL towards α-amylase and 7.93 mg/mL towards α-glucosidase. Thus, use of the PLE method allows o bioactive enriched fractions to be obtained from truffles with antidiabetic properties.

Association between free thyroxine levels and clinical phenotype in first-episode psychosis: a prospective observational study.

Aim: To determine whether thyroid hormone levels are associated with a specific clinical phenotype in patients with first-episode psychosis (FEP). Methods: Ninety-eight inpatients experiencing FEP and with less than 6 weeks of antipsychotic treatment were included in the study and were followed up for one year. Baseline psychiatric evaluation included assessment of prodromal symptoms, positive and negative symptoms, depressive symptoms, stressful life events and cycloid psychosis criteria. Thyroid function (thyroid-stimulating hormone (TSH) and free thyroxin (FT4)) was determined at admission. Partial correlation analysis was conducted to analyse the correlation between levels of TSH/FT4 and symptoms. Logistic regression was performed to explore the association between psychopathological symptoms, 12-month diagnoses and thyroid hormones while adjusting for covariates. Results: Patients with prodromal symptomatology showed lower baseline FT4 levels (OR = 0.06; p = 0.018). The duration of untreated psychosis (DUP) was inversely associated with FT4 concentrations (r =  - 0.243; p = 0.039). FEP patients with sudden onset of psychotic symptoms (criteria B, cycloid psychosis) showed higher FT4 levels at admission (OR = 10.49; p = 0.040). Patients diagnosed with affective psychotic disorders (BD or MDD) at the 12-month follow-up showed higher FT4 levels at admission than patients diagnosed with nonaffective psychosis (schizophrenia, schizoaffective) (OR = 8.57; p = 0.042). Conclusions: Our study suggests that higher free-thyroxine levels are associated with a specific clinical phenotype of FEP patients (fewer prodromal symptoms, shorter DUP duration and sudden onset of psychosis) and with affective psychosis diagnoses at the 12-month follow-up.

The impact of attention-deficit/hyperactivity disorder and specific learning disorders on academic performance in Spanish children from a low-middle- and a high-income population.

Introduction: Past research has demonstrated that attention-deficit/hyperactivity disorder (ADHD), specific learning disorders (SLD), and socioeconomic status (SES) affect a host of educational outcomes. However, there are no studies examining whether SES moderates the association between these neurodevelopmental disorders (ND) and the academic achievement of children and adolescents. The present investigation examined the impact of ADHD and SLD on academic performance in 1,287 Spanish students aged 5-17 from a low-middle (LM)- and a high-income population, when adjusted for comorbidity and demographic factors that may influence educational functioning. Methods: Parents completed a questionnaire regarding demographic data along with the Strengths and Difficulties Questionnaire. Additionally, teachers provided information on learning difficulties trough the Protocol for Detection and Management of Dyslexia. Teacher's Version. Academic performance across multiple domains (i.e., first language, foreign language, mathematics) was obtained from school records. ND were determined using standardized diagnostic methods based on the Diagnostic and Statistical Manual of Mental Disorders criteria. To examine the effects of ADHD and SLD on academic achievement and the potential moderating role of SES, a series of ordinal logistic regressions were conducted. Results: Emotional/behavioral problems, learning difficulties, and ND were more frequent among individuals from the LM-income population. After controlling for gender, age, parental divorce/separation, grade retention, frequency of screen use, and daily meals, both ADHD and SLD were associated with worse educational outcomes. Lower SES also increased the risk for academic impairment, although the interactions with ADHD or SLD were not significant. Conclusion: These findings indicate that ADHD and SLD exert a pervasive impact on academic performance across different socioeconomic backgrounds. Therefore, early detection and effective intervention strategies aimed at students with these ND are crucial to improve their educational functioning and mitigate the negative consequences related to academic problems.

Failure to rescue following anatomical lung resection. Analysis of a prospective nationwide database.

Background: Rescue failure has been described as an important factor that conditions postoperative mortality after surgical interventions. The objective of this study is to determine the incidence and main determinants of failure to rescue after anatomical lung resections. Methods: Prospective multicenter study that included all patients undergoing anatomical pulmonary resection between December 2016 and March 2018 and registered in the Spanish nationwide database GEVATS. Postoperative complications were classified as minor (grades I and II) and major (grades IIIa to V) according to the Clavien-Dindo standardized classification. Patients that died after a major complication were considered rescue failure. A stepwise logistic regression model was created to identify predictors of failure to rescue. Results: 3,533 patients were analyzed. In total, 361 cases (10.2%) had major complications, of which 59 (16.3%) could not be rescued. The variables associated with rescue failure were: ppoDLCO% (OR, 0.98; 95% CI, 0.96-1; p = 0.067), cardiac comorbidity (OR, 2.1; 95% CI, 1.1-4; p = 0.024), extended resection (OR, 2.26; 95% CI, 0.94-5.41; p = 0.067), pneumonectomy (OR, 2.53; 95 CI, 1.07-6.03; p = 0.036) and hospital volume <120 cases per year (OR, 2.53; CI 95%, 1.26-5.07; p = 0.009). The area under the curve of the ROC curve was 0.72 (95% CI: 0.64-0.79). Conclusion: A significant percentage of patients who presented major complications after anatomical lung resection did not survive to discharge. Pneumonectomy and annual surgical volume are the risk factors most closely related to rescue failure. Complex thoracic surgical pathology should be concentrated in high-volume centers to obtain the best results in potentially high-risk patients.

Extraction and trapping of truffle flavoring compounds into food matrices using supercritical CO2.

A supercritical fluid extraction methodology was used to extract flavoring and bioactive compounds from truffles. Some parameters such as CO2 flow rate (1-3 mg/mL), extraction time (15-90 min) and different trapping food matrices (grape seed oil, gelatin, agar agar and water) were optimized using response surface methodology to enhance extraction and trapping yields. The optimal conditions (2.27 mg/mL CO2 flow rate, 82.5 min when using 40 °C and 30 MPa, with 1 mL grape seed oil as trapping matrix) obtained with Tuber melanosporum were applied to three different truffle species: Terfezia claveryi, Tuber aestivum and Tuber indicum. A total of 32 metabolites were profiled in the extracts using ultra-high-performance supercritical fluid chromatography coupled to quadrupole time-of-flight mass spectrometry. Compounds such as brassicasterol ergosta-7,22-dienol, oleic and linoleic acid were found at similar amounts in all the extracts but other molecules (e.g. fungal sterols) showed a particular distribution depending on the specie studied and whether a trapping matrix was used at the SFE outlet.

Risk factors indicating the need for surgical therapy in patients with pyogenic liver abscesses.

BACKGROUND: Percutaneous drainage (PD) and antibiotics are the therapy of choice (non-surgical therapy [non-ST]) for pyogenic liver abscesses (PLA), reserving surgical therapy (ST) for PD failure. The aim of this retrospective study was to identify risk factors that indicate the need for ST. METHODS: We reviewed the medical charts of all of our institution's adult patients with a diagnosis of PLA between January 2000 and November 2020. A series of 296 patients with PLA was divided into two groups according to the therapy used: ST (n = 41 patients) and non-ST (n = 255). A comparison between groups was performed. RESULTS: The overall median age was 68 years. Demographics, clinical history, underlying pathology, and laboratory variables were similar in both groups, except for the duration of PLA symptoms < 10 days and leukocyte count which were significantly higher in the ST group. The in-hospital mortality rate in the ST group was 12.2% vs. 10.2% in the non-ST group (p = 0.783), with biliary sepsis and tumor-related abscesses as the most frequent causes of death. Hospital stay and PLA recurrence were statistically insignificant between groups. One-year actuarial patient survival was 80.2% in the ST group vs. 84.6% in the non-ST (p = 0.625) group. The presence of underlying biliary disease, intra-abdominal tumor, and duration of symptoms for less than 10 days on presentation comprised the risk factors that indicated the need to perform ST. CONCLUSIONS: There is little evidence regarding the decision to perform ST, but according to this study, the presence of underlying biliary disease or an intra-abdominal tumor and the duration of PLA symptoms < 10 days upon presentation are risk factors that should sway the surgeons to perform ST instead of PD.

Modifications in Abdominal Wall Graft Retrieval: When the Donor Closure Is Not Guaranteed.

BACKGROUND: Twenty percent of intestinal transplant recipients will require a surgical alternative to conventional primary abdominal wall closure. Abdominal wall transplant is a developing technique that is increasingly performed for this purpose in isolated intestinal or multivisceral recipients; however, adequate closure of the donor is paramount while simultaneously obtaining a large enough graft. The aim of this study is to describe alternative surgical techniques for closure of the donor in cases in which abdominal wall graft extraction hinders subsequent donor abdominal closure. METHODS: We describe the cases of 2 young donors in whom intestinal extraction was not carried out and in whom wall closure was not feasible, following standard techniques after abdominal wall graft extraction. We performed 2 different procedures to obtain adequate closure. 1. Hemifascia and hemiabdominal wall graft extraction: It is an option when the recipients require an extension of the abdominal aponeurosis yet have enough skin to guarantee skin closure. The perfusion of both epigastric arteries is needed. The remaining cutaneous half is used for closing the donor's abdomen.2. Hemiabdominal wall graft extraction: Full-thickness abdominal wall is harvested from the donor, selecting the most vascularized half. It is an alternative for recipients who need a skin implant in addition to an aponeurosis extension. This option should be used for recipients who do not require a large fascial graft but do require a significant cutaneous graft. The nontransplanted half of full-thickness abdominal wall is used for donor closure. RESULTS: Abdominal wall transplant allows for expansion of the abdominal cavity in organ recipients and reduces the risk of compartmental syndrome and subsequent ischemia. However, the donor wall defect must be considered. The choice of donation technique was based on the magnitude of the defect in the donor as well as the size of defect to be covered in the recipient while ensuring a tight and complete closure of the donor's abdomen. CONCLUSIONS: Abdominal wall graft extraction can be performed using nonconventional techniques that account for the extension and type of coverage needed by the recipient while guaranteeing proper closure of the donor.
