Beneficios y limitaciones de la planificación centrada en la persona en el campo de la discapacidad intelectual y del desarrollo: una revisión sistemática según las directrices de PRISMA / Benefits and limitations of person-centered planning in the field of intellectual and developmental disabilities: a systematic review according to PRISMA guidelines

La metodología de Planificación Centrada en la Persona (PCP) cada vez tiene mayor impacto en España. Comenzando desde las distintas legislaciones que regulan la atención a este colectivo en las diferentes autonomías y terminando en los centros que proveen este servicio. No obstante, existe escasa literatura internacional de estudios empíricos a grandes escalas que sitúen este enfoque metodológico en una posición relevante que garantice la eficacia de la PCP. El objetivo principal de este estudio es conocer el estado del uso de la metodología de PCP a través de estudios avalados empíricamente que sostengan tanto beneficios como limitaciones durante los últimos 10 años (2012-2022). Para ello, se ha realizado una revisión sistemática desde las directrices de PRISMA (2020), que incluye un total de 31 artículos. Como conclusión, se han descubierto más beneficios que limitaciones entre las que destacan las ventajas en su uso para las personas con discapacidad intelectual y del desarrollo y las mejoras de aspectos relacionados con la autodeterminación. No obstante, las limitaciones prevalecen por la falta de apoyos y recursos adecuados de las organizaciones para responder a una planificación centrada en la persona y la necesidad de formación de las personas implicadas en la elaboración de la PCP, lo que genera la incógnita de si se están realizando buenas prácticas en el uso de dicha metodología.

The methodology of Person Centered Planning (PCP) is having an increasing impact in Spain. Starting from the different legislations that regulate the attention to this group in the different autonomous regions and ending in the centers that provide this service. However, there is little international literature on large-scale empirical studies that place this methodological approach in a relevant position to guarantee the efficacy of PCP. The main objective of this study is to know the status of the use of PCP methodology through empirically supported studies that sustain both benefits and limitations during the last 10 years (2012-2022). For this purpose, a systematic review has been conducted since the PRISMA guidelines (2020), including a total of 31 articles. As a conclusion, more benefits than limitations have been found, among which the advantages in its use for people with intellectual and developmental disabilities and improvements in aspects related to self-determination stand out. However, limitations prevail due to the lack of adequate support and resources from organizations to respond to person-centered planning and the need for training of the people involved in the development of the PCP, which raises the question of whether good practices are being carried out in the use of this methodology.

Resultados obstétricos y perinatales tras la muerte fetal de un solo gemelo en un embarazo monocorial biamniótico: reporte de caso y revisión bibliográfica

ANTECEDENTES: Las gestaciones múltiples sugieren un mayor riesgo de mortalidad perinatal. Dentro de estas estadísticas, la muerte de un solo gemelo ocurre en hasta el 6% de los embarazos múltiples. La incidencia general después de las 20 semanas de gestación (sdg) se estima entre el 2.6% y el 6.2% de todos estos embarazos. Se ha demostrado que es la coriónicidad, más que la cigosidad, la que influye en el resultado de esta complicación, debido a la angioarquitectura placentaria de las circulaciones en los embarazos monocoriónicos. Las tasas de pérdida de hasta el 30-50% se han asociado con embarazos monocoriónicos y monoamnióticos. Si ocurre antes de las 14 sdg, el embrión puede desaparecer; entre las 14 y las 20 sdg, el feto se reduce en tamaño y volumen. Y, si ocurre después de 20 sdg, el feto permanece dentro del útero hasta el final de la gestación. CASO CLÍNICO: femenina de 18 años de edad, quien acudió a revisión obstétrica con reporte ultrasonográfico de un embarazo gemelar monocorial biamniótico de 30.4 sdg, y muerte de uno de los gemelos. Tras demostrar estabilidad hemodinámica del feto sobreviviente, así como estabilidad materna, se decidió internamiento para monitoreo estrecho. Una semana después desarrolló trabajo de parto pretérmino y se decidió la interrupción de la gestación de manera urgente. Se obtuvo un recién nacido masculino con edad gestacional sugestiva de 32 sdg, con dificultad respiratoria y requirió hospitalización para monitoreo estrecho del recién nacido prematuro. Madre egresó a las 48 horas, nunca desarrolló datos de coagulación intravascular diseminada (CID) y el recién nacido se mantuvo en hospitalización aproximadamente 3 semanas y media hasta que se egresó por adecuada adaptación. Nunca se demostró afectación neurológica o de algún otro órgano o sistema. CONCLUSIONES: Los factores más importantes al considerar el riesgo para el gemelo sobreviviente son la edad gestacional a la que ocurre la muerte del otro feto, y la corionicidad. El manejo debe incluir ecografías seriadas y programadas para el crecimiento. Estudios de Doppler arterial/venoso periférico e intracardiaco y una resonancia magnética al menos 3 semanas después de la muerte fetal para buscar cambios en el cerebro del gemelo sobreviviente. A pesar de que existen casos reportados de manejo conservador, es necesario el seguimiento estricto de datos de CID maternos, así como de desprendimiento prematuro de placenta normoinserta.

BACKGROUND: Multiple gestations suggest an increased risk of perinatal mortality. Within these statistics, death of a single twin occurs in up to 6% of multiple pregnancies. The overall incidence after 20 weeks gestation (sdg) is estimated to be between 2.6% and 6.2% of all such pregnancies. Chorionicity, rather than zygosity, has been shown to influence the outcome of this complication, due to the placental angioarchitecture of the circulations in monochorionic pregnancies. Loss rates of up to 30-50% have been associated with monochorionic and monoamniotic pregnancies. If it occurs before 14 sdg, the embryo may disappear; between 14 and 20 sdg, the fetus is reduced in size and volume. And, if it occurs after 20 sdg, the fetus remains inside the uterus until the end of gestation. CLINICAL CASE: 18-year-old female, who attended an obstetric check-up with an ultrasonographic report of a biamniotic monochorionic twin pregnancy of 30.4 sdg, and death of one of the twins. After demonstrating hemodynamic stability of the surviving fetus, as well as maternal stability, it was decided to hospitalize her for close monitoring. One week later she developed preterm labor and it was decided to terminate the pregnancy urgently. A male newborn was obtained with a gestational age suggestive of 32 sdg, with respiratory distress and required hospitalization for close monitoring of the premature newborn. Mother was discharged at 48 hours, never developed disseminated intravascular coagulation (DIC) and the newborn remained in hospital for approximately 3 and a half weeks until he was discharged due to adequate adaptation. No neurologic or other organ or system involvement was ever demonstrated. CONCLUSIONS: The most important factors when considering the risk to the surviving twin are the gestational age at which the death of the other fetus occurs, and chorionicity. Management should include serial and scheduled ultrasounds for growth. Peripheral arterial/venous and intracardiac Doppler studies and MRI at least 3 weeks after fetal death to look for changes in the brain of the surviving twin. Although there are case reports of conservative management, close monitoring of maternal DIC data, as well as normoinsert placental abruption, is necessary.     (provided by Infomedic International)

Severe Lung Dysfunction and Pulmonary Blood Flow during Extracorporeal Membrane Oxygenation.

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is indicated for patients with severe respiratory and/or circulatory failure. The standard technique to visualize the extent of pulmonary damage during ECMO is computed tomography (CT). PURPOSE: This single-center, retrospective study investigated whether pulmonary blood flow (PBF) measured with echocardiography can assist in assessing the extent of pulmonary damage and whether echocardiography and CT findings are associated with patient outcomes. METHODS: All patients (>15 years) commenced on ECMO between 2011 and 2017 with septic shock of pulmonary origin and a treatment time >28 days were screened. Of 277 eligible patients, 9 were identified where both CT and echocardiography had been consecutively performed. RESULTS: CT failed to indicate any differences in viable lung parenchyma within or between survivors and non-survivors at any time during ECMO treatment. Upon initiation of ECMO, the survivors (n = 5) and non-survivors (n = 4) had similar PBF. During a full course of ECMO support, survivors showed no change in PBF (3.8 ± 2.1 at ECMO start vs. 7.9 ± 4.3 L/min, p = 0.12), whereas non-survivors significantly deteriorated in PBF from 3.5 ± 1.0 to 1.0 ± 1.1 L/min (p = 0.029). Tidal volumes were significantly lower over time among the non-survivors, p = 0.047. CONCLUSIONS: In prolonged ECMO for pulmonary septic shock, CT was not found to be effective for the evaluation of pulmonary viability or recovery. This hypothesis-generating investigation supports echocardiography as a tool to predict pulmonary recovery via the assessment of PBF at the early to later stages of ECMO support.

Elective one-minute full brain multi-contrast MRI versus brain CT in pediatric patients: a prospective feasibility study.

BACKGROUND: Brain CT can be used to evaluate pediatric patients with suspicion of cerebral pathology when anesthetic and MRI resources are scarce. This study aimed to assess if pediatric patients referred for an elective brain CT could endure a diagnostic fast brain MRI without general anesthesia using a one-minute multi-contrast EPI-based sequence (EPIMix) with comparable diagnostic performance. METHODS: Pediatric patients referred for an elective brain CT between March 2019 and March 2020 were prospectively included and underwent EPIMix without general anesthesia in addition to CT. Three readers (R1-3) independently evaluated EPIMix and CT images on two separate occasions. The two main study outcomes were the tolerance to undergo an EPIMix scan without general anesthesia and its performance to classify a scan as normal or abnormal. Secondary outcomes were assessment of disease category, incidental findings, diagnostic image quality, diagnostic confidence, and image artifacts. Further, a side-by-side evaluation of EPIMix and CT was performed. The signal-to-noise ratio (SNR) was calculated for EPIMix on T1-weighted, T2-weighted, and ADC images. Descriptive statistics, Fisher's exact test, and Chi-squared test were used to compare the two imaging modalities. RESULTS: EPIMix was well tolerated by all included patients (n = 15) aged 5-16 (mean 11, SD 3) years old. Thirteen cases on EPIMix and twelve cases on CT were classified as normal by all readers (R1-3), while two cases on EPIMix and three cases on CT were classified as abnormal by one reader (R1), (R1-3, p = 1.00). There was no evidence of a difference in diagnostic confidence, image quality, or the presence of motion artifacts between EPIMix and CT (R1-3, p ≥ 0.10). Side-by-side evaluation (R2 + R4 + R5) reviewed all scans as lacking significant pathological findings on EPIMix and CT images. CONCLUSIONS: Full brain MRI-based EPIMix sequence was well tolerated without general anesthesia with a diagnostic performance comparable to CT in elective pediatric patients. TRIAL REGISTRATION: This study was approved by the Swedish Ethical Review Authority (ethical approval number/ID Ethical approval 2017/2424-31/1). This study was a clinical trial study, with study protocol published at ClinicalTrials.gov with Trial registration number NCT03847051, date of registration 18/02/2019.

Utility of abdominal ultrasound for diagnosis of hepatic steatosis in patients with morbid obesity.

Metabolic dysfunction-associated fatty liver disease is the most common cause of liver disease in our environment. The gold standard for diagnosis continues to be liver biopsy, although, since it is an invasive test, the most commonly used test for the initial diagnosis of steatosis is abdominal ultrasound. We present the results on the diagnostic utility of ultrasound for the detection of steatosis in the population of morbidly obese patients who underwent bariatric surgery from 2004 to 2019 in our centre.

Factors related to bladder catheterization in older patients and its possible association with prognosis: results of the EDEN-30 study. / Factores relacionados con la práctica de sondaje vesical en urgencias en pacientes ancianos y su relación con el pronóstico: resultados del estudio EDEN-30.

OBJECTIVES: The aims of this study in the Emergency Department and Elder Needs (EDEN) series were to explore associations between clinical variables on arrival at the ED (baseline) and the insertion of a bladder catheter, and the relation between catheterization and deterioration to a more complex or serious clinical state. MATERIAL AND METHODS: Included were all patients aged 65 years or older attended during 1 week in 52 Spanish EDs. Patients were grouped according to whether a bladder catheter was or was not inserted in the ED. We used multivariable logistical regression to explore associations between catheterization and patient age, sex, 10 comorbidities, 7 baseline status variables, and 6 clinical variables. Progression was considered serious or complex if the patient died or required hospitalization, a prolonged hospital stay, or discharge to a care facility. We also explored the association between age and catheterization using adjusted restricted cubic spline (RCS) curves with a cutoff value of 65 years. RESULTS: Participating hospitals enrolled 24 573 patients; bladder catheters were inserted in 976 (4%). Of these, 44.3% were discharged from the ED. Fifteen of the 24 variables were independently associated with bladder catheterization. Factors with the strongest associations according to odds ratios (ORs) were impaired consciousness (OR, 2.50; 95% CI, 1.90-3.30), dehydration (OR, 2.24; 95% CI, 1.85-2.72), and male sex (OR, 2.12; 95% CI, 1.84- 2.44). Age 80 years or older was also associated with bladder catheterization (OR, 1.17; 95% CI, 1.01-1.358). The adjusted RCS curves showed a progressive linear increase in the probability of catheterization with age. The increase was constant in men and stabilized after the age of 85 years in women (P-interaction .001). Bladder catheterization was associated with hospitalization (OR, 2.31; 95% CI, 1.99-2.68), intensive care unit admission (OR, 4.64; 95% CI, 3.04-7.09), prolonged stay in the ED for discharged patients (OR, 2.28; 95% CI, 1.75-2.96), in-hospital death (OR, 1.99; 95% CI, 1.54-2.57), and 30-day death (OR, 1.66; 95% CI, 1.33-2.08). No associations were found between catheterization and prolonged hospital stay (OR, 1.11; 95% CI, 0.92-1.34) or need for a care facility on discharge (OR, 1.50; 95% CI, 0.98-2.29). CONCLUSION: Certain patient characteristics and baseline clinical conditions are associated with bladder catheterization in patients of advanced age. The main factors were decreased consciousness, dehydration, and male sex. Even after adjustment for related factors, catheterization is independently associated with progression to more complex or serious clinical states.

OBJETIVO: Estudiar las variables de estado basal y de situación clínica a la llegada a urgencias relacionadas con la práctica de sondaje vesical (SV) en pacientes mayores, y si el SV está asociado a una evolución más compleja o grave. METODO: Se incluyeron todos los pacientes de edad 65 años atendidos durante una semana en 52 servicios de urgencias (SU) españoles, que fueron clasificados en función de si se practicó o no SV en el SU. Se investigó la relación de SV con edad, sexo, 10 variables de comorbilidad, 7 de estado basal y 6 de situación clínica mediante un modelo de regresión logística multivariable. Se consideró la evolución como grave o compleja si existió necesidad de hospitalización, estancia prolongada, necesidad de residencia al alta o muerte. La relación entre edad y SV se exploró también mediante curvas spline cúbicas restringidas (SCR) ajustadas, tomando la edad de 65 años como referencia. RESULTADOS: Se incluyeron 24.573 pacientes, de los que 976 (4%) recibieron SV. De éstos, el 44,3% fueron dados de alta desde urgencias. De las 25 variables exploradas, 15 se relacionaron independientemente con el SV, y las más manifiestas fueron disminución de consciencia (OR = 2,50, IC 95% = 1,90-3,30), deshidratación (OR = 2,24, IC 95% = 1,85-2,72) y sexo masculino (OR = 2,12, IC 95% = 1,84-2,44). La edad 80 años también se asoció a SV (OR = 1,17, IC 95% = 1,01-1,358), y las curvas SCR ajustadas mostraron un incremento progresivo y lineal de la probabilidad de SV con la edad, constante en hombres y que se estabilizaba a partir de los 85 años en mujeres (p interacción 0,001). El SV se asoció a necesidad de hospitalización (OR = 2,31, IC 95% = 1,99-2,68), hospitalización en intensivos (OR = 4,64, IC 95% = 3,04-7,09), estancia prolongada en urgencias en los pacientes dados de alta (OR = 2,28, IC 95% = 1,75-2,96) y mortalidad intrahospitalaria (OR = 1,99, IC 95% = 1,54-2,57) y a 30 días (OR=1,66, IC 95% = 1,33-2,08), pero no con hospitalización prolongada (OR = 1,11, IC 95% = 0,92-1,34) ni con necesidad de residencia al alta (OR = 1,50, IC 95% = 0,98-2,29). CONCLUSIONES: Determinadas características del paciente mayor y de su estado clínico se asocian con realizar un SV en urgencias, entre las que destacan la disminución de consciencia, la deshidratación y el sexo masculino. Aun teniendo en cuenta los factores asociados a SV en urgencias, este procedimiento se asocia independientemente con evoluciones más complejas o graves.

Cuando la obstrucción intestinalno es quirúrgica / When intestinal obstruction is not a surgical condition

We report the case of a middle-aged man who had undergone two diagnostic laparoscopies with no significant findings after he was attended at the emergency department with cramping pain, abdominal distention and vomiting, with radiological images simulating a small bowel obstruction. After multiple hospitalisations and an extensive set of tests, including a genetic study, he was diagnosed with chronic pseudo-obstruction, an uncommon, unrecognides syndrome with high morbidity. Being aware of this pathology can make it easier to diagnose, and thereby, we can avoid unnecessary surgical interventions, because its management and treatment are mainly based on pharmacological therapy. After a proper diagnosis our patient's progression was satisfactory due to the treatment introduced, with no further hospitalisations.(AU)

Synthesis of 2-aminopropyl benzopyran derivatives as potential agents against triple-negative breast cancer.

Synthesis of three series of 2-aminopropyl derivatives containing a benzopyran nucleus was performed to evaluate their performance against triple-negative breast cancer cell lines (MDA-MB-231 and MDA-MB-436) and normal breast epithelial cells (MCF10A). For the three series, the cytotoxic activity was as follows: N-methylated derivatives (tertiary amines) 5b, 6b, and 7b > secondary amine benzopyrans 5, 6, and 7 > quaternary amine salts 5c, 6c, and 7c > free phenolic derivatives 5a, 6a, and 7a. The structure-activity relationship showed the importance of the presence of an amine group and a p-fluorobenzyloxy substituent in the chromanol ring (IC50 values from 1.5 µM to 58.4 µM). In addition, 5a, 5b, 6a, and 7b displayed slight selectivity towards tumor cells. Compounds 5, 5a, 5b, 6, 6a, 6c, 7, and 7b showed apoptotic/necrotic effects due to, at least in part, an increase in reactive oxygen species generation, whereas 5b, 5c, 6b, 7a, and 7c caused cell cycle arrest in the G1 phase. Further cell-based mechanistic studies revealed that 5a, 6a, and 7b, which were the most promising compounds, downregulated the expression of Bcl-2, while 5b downregulated the expression of cyclins CCND1 and CCND2. Therefore, 2-aminopropyl benzopyran derivatives emerge as new hits and potential leads for developing useful agents against breast cancer.

Clinical Impact of New Treatment Strategies for HER2-Positive Metastatic Breast Cancer Patients with Resistance to Classical Anti-HER Therapies.

HER2-positive breast cancer accounts for 15-20% of all breast cancer cases. This subtype is characterized by an aggressive behavior and poor prognosis. Anti-HER2 therapies have considerably improved the natural course of the disease. Despite this, relapse still occurs in around 20% of patients due to primary or acquired treatment resistance, and metastasis remains an incurable disease. This article reviews the main mechanisms underlying resistance to anti-HER2 treatments, focusing on newer HER2-targeted therapies. The progress in anti-HER2 drugs includes the development of novel antibody-drug conjugates with improvements in the conjugation process and novel linkers and payloads. Moreover, trastuzumab deruxtecan has enhanced the efficacy of trastuzumab emtansine, and the new drug trastuzumab duocarmazine is currently undergoing clinical trials to assess its effect. The combination of anti-HER2 agents with other drugs is also being evaluated. The addition of immunotherapy checkpoint inhibitors shows some benefit in a subset of patients, indicating the need for useful biomarkers to properly stratify patients. Besides, CDK4/6 and tyrosine kinase inhibitors are also included in the design of new treatment strategies. Lapitinib, neratinib and tucatinib have been approved for HER2-positive metastasis patients, however clinical trials are currently ongoing to optimize combined strategies, to reduce toxicity, and to better define the useful setting. Clinical research should be strengthened along with the discovery and validation of new biomarkers, as well as a deeper understanding of drug resistance and action mechanisms.

Hematoma post-endoscopic retrograde cholangiopancreatography.

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most frequently performed procedures in the treatment of biliary-pancreatic diseases. Hematoma after ERCP is an infrequent and highly serious complication. We present three cases with hepatic hematoma after a CPRE.

Differences in glucose metabolic activity in liver metastasis separates two groups of metastatic uveal melanoma patients with different prognosis.

BACKGROUND: Uveal melanoma metastasizes to the liver. We aimed to explore the metabolic activity of liver metastases (LM) as a biomarker for survival. METHODS: We analyzed newly diagnosed patients with metastatic UM (MUM) with LM detected by liver-directed imaging and had undergone a PET/CT at diagnosis. FINDINGS: 51 patients were identified between 2004 and 2019. Median age was 62 years, 41% male and 22% ECOG ≥1. LDH, ALP, and GGT were elevated in 49%, 37%, and 57% of patients. Median LM SUVmax was 8.5 (3-42.2). Same size lesions presented a wide range of metabolic activity. Median OS was 17.3 m (95% CI:10.6-23.9). Patients with SUVmax ≥8.5 had an OS of 9.4 m (95% CI:6.4-12.3), whereas patients with SUVmax <8.5 had an OS of 38.4 m (95% CI:21.4-55.5; p < 0.0001, HR = 2.9). We observed similar results when studying M1a disease separately. Multivariate analysis showed SUVmax as an independent prognostic factor for the whole population and those with M1a disease. INTERPRETATION: Increased metabolic activity of LM seems to be an independent predictor of survival. MUM is a heterogeneous disease and metabolic activity probably reflects a different intrinsic behavior.

Ventriculoperitoneal shunt survey in pediatric patients in an emergency setting: a comparison between ultra-low-dose CT using a tin filter and plain radiography.

OBJECTIVE: The aim of this study was to investigate the diagnostic performance, effective radiation dose, and examination time of ventriculoperitoneal shunt evaluation using full-body ultra-low-dose CT (ULD CT) with a tin filter compared with digital plain radiography in a pediatric population. METHODS: A retrospective cross-sectional study was conducted in an emergency setting. Data from 143 children were collected. Sixty were examined with ULD CT with a tin filter and 83 with digital plain radiography methods. Effective doses and times were compared between the two methods. Two observers in pediatric radiology evaluated the patient images. Clinical findings and results from shunt revision, if it was performed, were used to evaluate the diagnostic performance between modalities. An examination-room simulation was performed of the two methods to estimate representative examination times. RESULTS: The mean effective radiation dose for ULD CT with the tin filter was estimated to be 0.29 ± 0.16 mSv compared with 0.16 ± 0.19 mSv for digital plain radiography, with both examinations associated with a very low lifetime attributable risk (< 0.01%). The shunt tip could be more reliably located with ULD CT. ULD CT also allowed assessment of additional findings to explain patient symptoms, such as a cyst at the tip of the shunt catheter and the presence of an obstructing rubber nipple in the duodenum that could not have been observed on a plain radiograph. The examination time with ULD CT of the shunt was estimated to be 20 minutes. The examination time of the shunt with digital plain radiography, including the examination itself time and transfer of the patient between rooms, was estimated to be 60 minutes. CONCLUSIONS: ULD CT using a tin filter allows good visualization of the position or disruption of the shunt catheter that is comparable or superior to plain radiography, at a higher dose, while providing additional findings and reduced patient discomfort.

miR-146a-5p Promotes Angiogenesis and Confers Trastuzumab Resistance in HER2+ Breast Cancer.

Trastuzumab treatment has significantly improved the prognosis of HER2-positive breast cancer patients. Despite this, resistance to therapy still remains the main clinical challenge. In order to evaluate the implication of microRNAs in the trastuzumab response, we performed a microRNA array in parental and acquired trastuzumab-resistant HER2-positive breast cancer cell lines. Our results identified miR-146a-5p as the main dysregulated microRNA. Interestingly, high miR-146a-5p expression in primary tumor tissue significantly correlated with shorter disease-free survival in HER2-positive breast cancer patients. The gain- and loss-of-function of miR-146a-5p modulated the response to trastuzumab. Furthermore, the overexpression of miR-146a-5p increased migration and angiogenesis, and promoted cell cycle progression by reducing CDKN1A expression. Exosomes from trastuzumab-resistant cells showed a high level of miR-146a-5p expression compared with the parental cells. In addition, the co-culture with resistant cells' exosomes was able to decrease in sensitivity and increase the migration capacities in trastuzumab-sensitive cells, as well as angiogenesis in HUVEC-2 cells. Collectively, these data support the role of miR-146a-5p in resistance to trastuzumab, and demonstrate that it can be transferred by exosomes conferring resistance properties to other cells.

MALT lymphoma of the colon: an endoscopic challenge.

Colonic lymphoma involving the mucosa-associated lymphoid tissue (MALT) is an uncommon pathology, with an unknown pathogenesis and varied endoscopic appearance. We present the case of a 78-year-old female with challenging endoscopic findings that resulted in the diagnosis of a colonic MALT lymphoma.

Influence of Executive Function Training on BMI, Food Choice, and Cognition in Children with Obesity: Results from the TOuCH Study.

BACKGROUND: Children with obesity have a higher risk of future health and psychological problems. Executive functions (EFs) play a key role in successful dietetic and exercise planning; therefore, new treatments aimed at improving EFs may optimize outcomes. OBJECTIVES: This study evaluates the impact of EF training on body mass index (BMI), food choice, and cognition in children with obesity. We also examine their real-life executive functioning, emotional state, and quality of life. METHODS: Randomized controlled double-blind trial. Forty-six children with obesity were randomly allocated into an executive functions training or a control task training group and attended 30-45 min of daily training (5/week over 6 weeks), with both groups receiving counseling on diet and wearing an activity/sleep tracker. Participants were evaluated at baseline and after treatment. RESULTS: BMI decreased over time in the whole sample, although there were no differences between groups at post-training in BMI, food choice, and cognition. Both groups showed significant improvements in attention, speed, cognitive flexibility, and inhibitory control. Additionally, there were some benefits in real-life executive functioning and self-esteem. Over the 6 weeks, participants showed worse food choices in both groups. CONCLUSIONS: EFs training showed a lack of significant effects. The executive function enhancement alone did not explain these changes, as there were no significant differences between the experimental groups. It might be that the control task training could also produce some benefits, and multi-component interventions might be useful for weight loss.

High VEGFR3 Expression Reduces Doxorubicin Efficacy in Triple-Negative Breast Cancer.

Due to the lack of specific targets, cytotoxic chemotherapy still represents the common standard treatment for triple-negative breast patients. Despite the harmful effect of chemotherapy on tumor cells, there is evidence that treatment could modulate the tumor microenvironment in a way favoring the propagation of the tumor. In addition, the lymphangiogenesis process and its factors could be involved in this counter-therapeutic event. In our study, we have evaluated the expression of the main lymphangiogenic receptor VEGFR3 in two triple-negative breast cancer in vitro models, resistant or not to doxorubicin treatment. The expression of the receptor, at mRNA and protein levels, was higher in doxorubicin-resistant cells than in parental cells. In addition, we confirmed the upregulation of VEGFR3 levels after a short treatment with doxorubicin. Furthermore, VEGFR3 silencing reduced cell proliferation and migration capacities in both cell lines. Interestingly, high VEGFR3 expression was significantly positively correlated with worse survival in patients treated with chemotherapy. Furthermore, we have found that patients with high expression of VEGFR3 present shorter relapse-free survival than patients with low levels of the receptor. In conclusion, elevated VEGFR3 levels correlate with poor survival in patients and with reduced doxorubicin treatment efficacy in vitro. Our results suggest that the levels of this receptor could be a potential marker of meager doxorubicin response. Consequently, our results suggest that the combination of chemotherapy and VEGFR3 blockage could be a potentially useful therapeutic strategy for the treatment of triple-negative breast cancer.
