Factores asociados a la decisión paterna sobre el retorno a clases presenciales en Colombia durante la pandemia COVID-19

Introducción: la pandemia por SARS-CoV-2 generó el cierre de los colegios y el inicio de la educación virtual,como medida para disminuir la propagación del virus. Rápidamente, se planteó el regreso a los colegios; sinembargo, es probable que exista un rechazo de los padres por el regreso a clases de forma presencial o mediante alternancia. Por esta razón, se evaluaron los factores asociados a esta oposición. Materiales y métodos: se realizó un estudio analítico de corte transversal mediante una encuesta, dirigida a padres que acuden a consultorios con sus hijos en varias ciudades de Colombia. Se determinó el porcentaje de padres que deseaban mantener la escolarización mediante la virtualidad y los factores asociados que motivan a no aceptar el pronto retorno a clases presenciales. Se realizó un análisis de regresión binomial para estimar razones de prevalencia (RP), ajustado a la edad de los padres, tomando como variable dependiente la aceptación de la virtualidad como estrategia para no regresar a los colegios, y se determinaron los factores de mayor importancia en la no aceptación del retorno a clases. Resultados: el 81,06 % de los padres no acepta el retorno a clase de forma presencial. El principal factor asociados a esta decisión fue quealguno de los padres presentara alguna comorbilidad, principalmente, hipertensión y obesidad. Tener hijos mayores de 10 años (RP: 2,64: IC 95 %: 1,48-4,72), convivir con personas mayores de 70 años (RP: 2,2; IC 95 %; 1,46-3,29) y conocer alguna persona fallecida por COVID-19 (RP: 1,86; IC 95 %: 1,42-2,44) también fueron asociadas a no aceptar el retorno a clase presencial. Conclusiones: existe una clara tendencia a mantener la virtualidad como opción educativa en Colombia para el no regreso a clases presenciales en población de estrato medio y alto. Los factores asociados sugieren una forma de protección familiar. Esta evidencia debe considerarse específica para el periodo de recolección de datos y el grupo incluido en el estudio. Se requieren estudios en los estratos socioeconómicos más bajos, donde se supone ocurren más efectos adversos asociados al no retorno a clases presenciales. Introducción: la pandemia por SARS-CoV-2 generó el cierre de los colegios y el inicio de la educación virtual,como medida para disminuir la propagación del virus.

However, there is likely a rejection of parents to return to classes in person. For this reason, the factors possibly associated with this opposition were evaluated. Material and methods: A cross-sectional analytical study was carried out through an online survey aimed at parents who attend private clinics with their children, in several cities of Colombia. The percentage of parents who wished to maintain their children›s schooling through virtuality and the factors associated with not accepting the prompt return to faceto-face classes were determined. A binomial regression analysis, to estimate Prevalence Ratios (PR), adjusted for the age of the parents was carried out, taking as a dependent variable the acceptance of virtuality as a strategy for not returning to school and the most important factors in the non-acceptance of returning to school were determined. Results: 81.06% of the parents did not accept the return to class in person. The main factors associated with this decision were that one of the parents had some comorbidity, mainly hypertension, and obesity. Having children older than 10 years (PR: 2.64; 95% CI: 1.48-4.72), living with people older than 70 years (PR: 2.2; 95% CI;1.46-3.29), and knowing someone who died from COVID-19 (PR: 1.86; 95% CI 1.42-2.44) were associated with not accepting the return to face classes. Conclusions: There is a clear tendency to maintain virtuality as an educationaloption in Colombia for not returning to face-to-face classes in the middle and upper stratum population. Associated factors suggest a form of family protection. This evidence should be considered specific for the data collection period and the group included in the study. Studies are required in the lowest socioeconomic strata, where it is assumed that there are more adverse effects associated with not returning to face-to-face classes.&nbsp

Heart-brain synchronization breakdown in Parkinson's disease

Heart rate variability (HRV) abnormalities are potential early biomarkers in Parkinson's disease (PD) but their relationship with central autonomic network (CAN) activity is not fully understood. We analyzed the synchronization between HRV and brain activity in 31 PD patients and 21 age-matched healthy controls using blood-oxygen-level-dependent (BOLD) signals from resting-state functional brain MRI and HRV metrics from finger plethysmography recorded for 7.40 min. We additionally quantified autonomic symptoms (SCOPA-AUT) and objective autonomic cardiovascular parameters (blood pressure and heart rate) during deep breathing, Valsalva, and head-up tilt, which were used to classify the clinical severity of dysautonomia. We evaluated HRV and BOLD signals synchronization (HRV-BOLD-sync) with Pearson lagged cross-correlations and Fisher's statistics for combining window-length-dependent HRV-BOLD-Sync Maps and assessed their association with clinical dysautonomia. HRV-BOLD-sync was lower significantly in PD than in controls in various brain regions within CAN or in networks involved in autonomic modulation. Moreover, heart-brain synchronization index (HBSI), which quantifies heart-brain synchronization at a single-subject level, showed an inverse exposure-response relationship with dysautonomia severity, finding the lowest HBSI in patients with severe dysautonomia, followed by moderate, mild, and, lastly, controls. Importantly, HBSI was associated in PD, but not in controls, with Valsalva pressure recovery time (sympathetic), deep breathing E/I ratio (cardiovagal), and SCOPA-AUT. Our findings support the existence of heart-brain de-synchronization in PD with an impact on clinically relevant autonomic outcomes.We want to thank all the patients and participants involved in the study.

Retinal thickness predicts the risk of cognitive decline in Parkinson's disease

Objective: To analyze longitudinal changes of retinal thickness and their predictive value as biomarkers of disease progression in idiopathic Parkinson’s disease (iPD). Methods: Patients with Lewy body diseases (LBDs) were enrolled and prospectively evaluated at 3 years, including patients with iPD (n=42), dementia with Lewy bodies (DLB, n=4), E46K-SNCA mutation carriers (n=4) and controls (n=17). All participants underwent Spectralis retinal optical coherence tomography and Montreal Cognitive Assessment (MoCA), and Unified Parkinson’s Disease Rating Scale (UPDRS) score was obtained in patients. Macular ganglion-inner plexiform layer complex (GCIPL) and peripapillary retinal nerve fiber layer (pRNFL) thickness reduction rates were estimated with linear mixed models. Risk ratios were calculated to evaluate the association between baseline GCIPL and pRNFL thickness and the risk of subsequent cognitive and motor worsening, using clinically meaningful cut-offs. Results: GCIPL thickness in the parafoveal region (1- to 3-mm ring) presented the largest reduction rate. The annualized atrophy rate was 0.63 µm in iPD patients and 0.23 µm in controls (p<0.0001). iPD patients with lower parafoveal GCIPL and pRNFL thickness at baseline presented an increased risk of cognitive decline at 3 years (RR 3.49, 95% CI 1.10 – 11.1, p=0.03 and RR 3.28, 95% CI 1.03 – 10.45, p=0.045, respectively). We did not identify significant associations between retinal thickness and motor deterioration. Interpretation: Our results provide evidence of the potential use of OCT-measured parafoveal GCIPL thickness to monitor neurodegeneration and to predict the risk of cognitive worsening over time in iPD

Goodbye Hartmann trial: a prospective, international, multicenter, observational study on the current use of a surgical procedure developed a century ago

Background: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6&nbsp;years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P &lt; 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. Conclusions: After 100&nbsp;years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception

[Effect of weight gain on the development of gestational diabetes]

&lt;p&gt;&lt;strong&gt;Abstract:&nbsp;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Background:&nbsp;&lt;/strong&gt;Gestational diabetes mellitus (GDM) refers to diabetes diagnosed in the second or third trimester of pregnancy. Assessing the weight gain in each pregnant women's appointment is a common task of primary care during their visit. However, the implications of this increase in weight for the development of GDM are unknown.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective:&nbsp;&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&nbsp;Evaluate if the greater than expected weight gain (HEWG) in pregnancy is a risk factor for the development of GDM.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods:&lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&nbsp;Analytical, observational, longitudinal, retrolective study, which included pregnant women between 15 and 40 years of age with complete follow-up of the pregnancy with &gt; 2 prenatal check-ups, somatometry and complete medical history was made. During follow-up, the GPME was determined. Odds ratio (OR) and 95% confidence intervals (95% CI) were calculated. Variables with significance were entered into a multiple logistic regression model (MLR), where the dependent variable was DMG.&nbsp;The sample size calculation was for convenience.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results:&lt;/strong&gt; 1000 pregnant women with a median age of 28 years were included. In the MLR The pre-gestational body mass index (BMI) with overweight had an RM of 1.3 (95% CI 0.86-1.98), BMI with obesity an OR of 2.57 (95% CI 1.6-4.14), the HEWG during pregnancy had an OR 1.14 95% CI (0.71-1.81), Age&gt; 30 years shows an RM of 2.24 (95% CI 1.55-3.25).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusions:&lt;/strong&gt; HEWG during pregnancy is not an independent risk factor for the development of GDM. The main ones are age&gt; 30 years and pre-gestational obesity.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Introducción:&nbsp;&lt;/strong&gt;la diabetes mellitus gestacional (DMG) se refiere a la diabetes diagnosticada a partir del segundo trimestre del embarazo.&nbsp;Evaluar el incremento de peso de mujeres embarazadas es una labor habitual en la consulta del primer nivel de atención. Sin embargo, se desconocen las implicaciones que tiene este incremento ponderal para el desarrollo de DMG.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objetivo:&lt;/strong&gt; evaluar si la ganancia ponderal mayor a la esperada (GPME) en el embarazo es factor de riesgo para el desarrollo de DMG.&nbsp;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Métodos:&lt;/strong&gt; estudio analítico, observacional, longitudinal, retrolectivo, que incluyó a embarazadas de 15 a 40 años con seguimiento completo del embarazo con más de dos consultas de control prenatal, somatometría e historia clínica completa.&nbsp;Durante el seguimiento se determinó la GPME. Se calculó razón de momios (RM) e intervalos de confianza del 95% (IC95%). Las variables con significancia se ingresaron a un modelo de regresión logística múltiple (RLM), en donde la variable de desenlace fue DMG.&nbsp;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Resultados:&lt;/strong&gt;&nbsp;se incluyeron a 1000 embarazadas con mediana de edad de&nbsp;28 años. En la RLM el índice de masa corporal (IMC) pre-gestacional con sobrepeso tuvo una RM de 1.3 (IC95%: 0.86-1.98), IMC con obesidad una RM de 2.57 (IC95%: 1.6-4.14), la GPME durante el embarazo tuvo una RM de 1.14 (IC95%: 0.71-1.81) y la edad &gt; 30 años una RM de 2.24 (IC95%: 1.55-3.25).&nbsp;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusiones:&lt;/strong&gt;&nbsp;la GPME durante el embarazo no es un factor de riesgo independiente para el desarrollo de DMG. Los principales son la edad &gt;30 años y la obesidad pregestacional.&lt;/p&gt

Characterization of molecular biomarkers in cerebrospinal fluid and serum of E46K-SNCA mutation carriers

Introduction: Blood and cerebrospinal fluid represent emerging candidate fluids for biomarker identification in Parkinson's disease (PD). Methods: We studied 8 individuals carrying the E46K-SNCA mutation (3 PD dementia (PDD), 1 tremor-dominant PD, 2 young rigid-akinetic PD and 2 asymptomatic) and 8 age- and sex-matched healthy controls. We quantified the levels of total alpha-synuclein (a-syn), neurofilament light chain (NfL), glial fibrillary acidic protein (GFAP), Tau and ubiquitin carboxy-terminal hydrolase L1 (UCHL1) with SiMoA (Quanterix) in cerebrospinal fluid (CSF) of mutation carriers and in serum of all participants. The correlation between the concentration of biofluid markers and clinical outcomes was evaluated. Results: Although based on a small number of cases, CSF a-syn was decreased in symptomatic E46K-SNCA carriers compared to the asymptomatic ones. Asymptomatic carriers exhibited similar serum biomarker levels as compared to matched controls, except for serum a-syn, which was higher in asymptomatic individuals. Carriers with PDD diagnosis displayed increased levels of serum NfL and GFAP compared to matched controls. These findings highly correlated with cognitive and motor status of E46K-SNCA carriers, but not with disease duration. Conclusions: Patients with familial forms of neurodegenerative disease exhibit variable penetrance of the phenotype and are exceptionally valuable for delineating biomarkers. Serum and CSF molecular biomarkers in E46K-SNCA mutation carriers show that a-syn might be suitable to track the conversion from asymptomatic to PD, whereas NfL and GFAP might serve to foresee the progression to PD dementia. These findings should be interpreted with caution and need to be replicated in other genetic synucleinopathy cohorts

External Validity of Somatostatin Analogs Trials in Advanced Neuroendocrine Neoplasms: The GETNE-TRASGU Study

[Introduction] Somatostatin analogs (SSA) prolong progression-free survival (PFS) in patients with well-differentiated gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs). However, the eligibility criteria in randomized clinical trials (RCTs) have been restricted, which contrasts with the vast heterogeneity found in NENs.[Methods] We identified patients with well-differentiated (Ki-67% ≤20%), metastatic GEP-NENs treated in first line with SSA monotherapy from the Spanish R-GETNE registry. The therapeutic effect was evaluated using a Bayesian Cox model. The objective was to compare survival-based outcomes from real-world clinical practice versus RCTs.[Results] The dataset contained 535 patients with a median age of 62 years (range: 26–89). The median Ki-67% was 4 (range: 0–20). The most common primary tumor sites were as follows: midgut, 46%; pancreas, 34%; unknown primary, 10%; and colorectal, 10%. Half of the patients received octreotide LAR (n = 266) and half, lanreotide autogel (n = 269). The median PFS was 28.0 months (95% CI: 22.1–32.0) for octreotide versus 30.1 months (95% CI: 23.1–38.0) for lanreotide. The overall hazard ratio for lanreotide versus octreotide was 0.90 (95% credible interval: 0.71–1.12). The probability of effect sizes >30% with lanreotide versus octreotide was 2 and 6% for midgut and foregut NENs, respectively.[Conclusion] Our study evaluated the external validity of RCTs examining SSAs in the real world, as well as the main effect-modifying factors (progression status, symptoms, tumor site, specific metastases, and analytical data). Our results indicate that both octreotide LAR and lanreotide autogel had a similar effect on PFS. Consequently, both represent valid alternatives in patients with well-differentiated, metastatic GEP-NENs.The study has been funded by a restricted grant from Novartis Farmacéutica, S.A.
