Published: February 2022

Hoy en día la movilidad es un problema de las ciudades [1] que puede ser resuelto por nuevas tecnologías como la visión computacional y algoritmos de optimización para diseñar sistemas de control que puedan adaptarse a los fenómenos de flujo vehicular que existen en las ciudades, para evitar la congestión y optimizar el flujo vehicular, reduciendo los tiempos de espera y mejorando la coordinación de distribución de los tiempos de espera de los semáforos en las intersecciones; por estas razones proponemos un enfoque de semáforo inteligente basado en prioridades que miden el número de vehículos que pasan en las calles con una cámara de video y distribuyen el tiempo dependiendo de la capacidad de flujo de las calles en una intersección aislada, en los resultados se puede observar que el tamaño de las colas de espera y los tiempos se reducen significativamente.

En este artículo se presenta una reflexión sobre las tecnologías y la relación técnica-sujetocultura que se da en sociedad y le permite al sujeto construir un conocimiento científico que genere transformaciones significativas en las vidas, las experiencias o en las formas de convivir y habitar el mundo.Para ello, se abordan temáticas como la tecnología, el cuerpo, el sujeto y la formación humana, esta última vista como un instrumento de identidad sociocultural que se inscribe, a su vez, en un contexto donde se configura la construcción del yo, del nosotros y se abre a un diálogo intersubjetivo para definir de manera colectiva las realidades.Con la tecnología se han alcanzado cientos de beneficios para la humanidad en su historia, en la actualidad, el camino hacia la innovación y el desarrollo científico son necesidades vigentes en las agendas de los gobiernos en los cuáles se invierten recursos, esfuerzos y se contemplan expectativas de crecimiento. Es precisamente en medio de estas demandas sociales donde profundizar en el terreno de la formación y la educación cobra sentido en tanto se pueda repensar de qué manera convivimos con los avances, para qué los creamos, cómo estos artefactos hacen parte del yo o se instauran en el cuerpo, y se responde en términos de realización humana cuál es la vida que deseo.Finalmente, se concluye que las tecnologías no son una problemática cuando se les da un uso reflexivo en sociedad, es decir, se cuestionan desde diferentes perspectivas su rol e impacto. La formación en este sentido aportará la pregunta sobre la imagen social que se desea construir y de manera crítica analizará los cambios, las permanencias, los elementos inesperados desde lasospecha y no de una adopción sumisa para lograr aprender constantemente del entorno cuya característica principal es el bienestar y las relaciones interpersonales en un proceso de humanización.

Published: February 2022

En el campo de investigación en psicología del testimonio se ha estudiado el efecto de múltiples factores psicológicos sobre la cantidad de detalles, la reproducción de conversaciones y las falsas memorias en el recobro de eventos autobiográficos. El objetivo de esta investigación es identificar el efecto de la personalidad sobre el recobro de testigos presenciales de actos con violencia verbal y no verbal. Participaron 40 estudiantes de psicología divididos en cuatro grupos en términos de sus puntuaciones altas en los estilos de personalidad histriónica (Grupo 1), esquizoide (Grupo 2), obsesiva-compulsiva (Grupo 3), y un grupo control con puntuaciones promedio en dichos estilos (Grupo 4). Mediante una situación experimental se presentó a los participantes un video con contenido de violencia verbal o física; posteriormente se realizó una tarea de recobro libre y se evaluó la cantidad de detalles, la reproducción de conversaciones y las falsas memorias. Los resultados mostraron que los participantes del Grupo 1 evidenciaron recobros pobres en detalles, con deficiente precisión en la reproducción de conversaciones y ausencia de falsas memorias, mientras que los participantes de los grupos 2 y 3 recobraron la información con mayor cantidad de detalles y mayor precisión en la reproducción de conversaciones, aunque el Grupo 3 obtuvo la mayor cantidad de falsas memorias. Estos hallazgos son discutidos en términos de la relación entre la forma en que se recobra la información en los procesos de Memoria Autobiográfica en escenarios jurídicos, y que hay otros constructos asociados como la personalidad y la emoción que pueden influir en el testimonio.

Published: February 2022

AimsThe “early repolarization” (ER) pattern and J wave are frequent findings on standard ECG. Controversial data have recently been reported about their prognostic implications in healthy subjects, but no longitudinal prospective study specifically designed to investigate their long-term prognostic value has hitherto been published.Methods and ResultsWe prospectively enrolled 4,176 consecutive subjects with no evidence of cardiovascular disease who were referred for standard ECG recording for routine check-ups or pre-operative assessments for non-cardiovascular surgery. ECGs were prospectively assessed for the presence of ER/J wave. A 10-year follow-up was available for 3,937 patients (94.3%), 660 of whom (16.8%) showed ER/J wave whereas 3,277 did not. A total of 644 deaths occurred (16.3%), 116 (2.95%) of which were attributed to cardiovascular causes. Both total and cardiovascular mortality adjusted for clinical and laboratory variables did not differ significantly between patients with vs. without ER/J wave (HR 0.94; 95% CI 0.75–1.19; p = 0.63 and HR 0.61; 95% CI 0.31–1.21; p = 0.16, respectively). No significant association with total and cardiovascular mortality was also found in pre-specified analyses for ER and J wave alone, ER/J wave detected in specific ECG regions (i.e., inferior, lateral, precordial), and type of J wave (notched or slurred).ConclusionIn this specifically designed prospective study of individuals without any evidence of cardiovascular disease, we found no significant association of ER/J wave with the risk of the total as well as cardiovascular mortality during long-term follow-up.

BackgroundMycoplasma hominis is a small cell-wall-free organism, part of the normal microbiota of the genitourinary tract. It is rarely involved in extragenital infections, mainly joint, surgical-site, and respiratory infections.MethodsWe describe a case of M. hominis subdural empyema and lower limb surgical site infections, following decompressive craniotomy, after traumatic brain and extremities injury. In addition, a literature review of 34 cases M. hominis CNS infections was done.ResultsOur case depicts a 25-years old patient who developed subdural empyema and surgical site infections in his cranium and fibula. Both sites were cultured, and small pinpoint colonies grew on blood agar. MALDI-TOF MS identified M. hominis. Simultaneously 16S-rDNA PCR from CSF detected M. hominis. Antimicrobial treatment was switched to doxycycline with improvement. Literature review revealed 21 adults and 13 pediatric cases of M. hominis CNS infection. Risk factors in adults were head trauma, neurosurgery, or post-partum period.ConclusionsBased upon the literature reviewed, we postulate that adult patients with head trauma or neurosurgical procedure, rarely are infected either through direct contamination during the trauma, or by undergoing urgent, urinary catheterization, and may experience distant infection due to translocation of M. hominis into the bloodstream. In such cases diagnosis is delayed due to difficulties in growing and identifying the bacteria. Empiric antimicrobials are usually not effective against mycoplasmas. These factors contributed to the mortality in adult cases (15%). Our rare case highlights the necessity of combining classical microbiology routines with advanced molecular techniques to establish a diagnosis in complicated cases.

BackgroundSubnormothermic machine perfusion (SNMP) of liver grafts is currently less clinically developed than normothermic and hypothermic approaches, but may have logistical advantages. At intermediate temperatures, the oxygen demand of the graft is low enough to be satisfied with an acellular perfusate, obviating the need for oxygen carrying molecules. This intermediate metabolic rate, however, is sufficient to support the production of bile, which is emerging as an important indicator of graft injury and viability. In this study, we hypothesized that the biliary compartment would be more sensitive than perfusate in detecting graft injury during SNMP.MethodsTo test this hypothesis in a rat model, we performed liver transplants with DCD and control liver grafts after 1 h of acellular room temperature machine perfusion (acRTMP) or static cold storage (SCS). Point of care liver function tests were measured in biliary and perfusate samples after 1 h of machine perfusion. Following transplantation, rats were sacrificed at 24 h for assessment of post-transplant graft function and histology.ResultsAll point-of-care liver function tests were significantly more concentrated in the biliary compartment than the perfusate compartment during acRTMP. DCD liver grafts could be distinguished from control liver grafts by significantly higher markers of hepatocyte injury (AST, ALT) in the biliary compartment, but not in the perfusate compartment. Classical markers of cholangiocyte injury, such as gammy-glut amyl transferase (GGT), amylase (AML), and alkaline phosphatase were detectable in the biliary compartment, but not in the perfusate compartment. In comparison to SCS, graft preservation by acRTMP produced a significant survival benefit in DCD liver transplantation (75 vs. 0%, p &lt; 0.0030).ConclusionTogether, these findings demonstrate that during acRTMP, the biliary compartment may be a more sensitive indicator of graft injury than the perfusate compartment. Moreover, acRTMP provides superior graft preservation to SCS in rat DCD liver transplantation.

Published: February 2022

PurposeTo analyze the level of sex hormone in relation to keratoconus (KC).MethodsSixty-two eyes of 62 patients (12 females, 50 males) classified as KC and 120 eyes of 120 patients (21 females, 99 males) with mild to moderate myopia and astigmatism were analyzed. Plasma samples were collected and analyzed using a chemiluminescence immunoassay to determine the concentrations of estriol (E3), estradiol (E2), progesterone (P), and testosterone (T). Corneal morphological parameters, such as the central corneal thickness (CCT), thinnest corneal thickness (TCT), and maximum simulated keratometry (Kmax), were measured using Pentacam and Sirius.ResultsThe mean age was 23.73 ± 5.16 years for patients with KC and 23.68 ± 6.10 years for patients treated with laser vision correction (LVC). Among the patients with KC, 12 were female (19.35%) and 50 were male (80.65%). The majority of patients with KC were between 20 and 30 years old. In female patients, the concentration of T in the KC group was significantly lower than that in the LVC group (0.86 ± 0.33 vs. 1.18 ± 0.58 nmol/L; P = 0.044). There were positive correlations between T, CCT (r = 0.395, P = 0.023) and TCT (r = 0.378, P = 0.030) in female patients. In male patients, E2 was higher in the KC group than the LVC group (143.75 ± 34.82 vs. 124.80 ± 43.56 pmol/L; P = 0.013), while T was significantly lower (11.59 ± 2.85 vs. 13.58 ± 4.77 nmol/L; P = 0.026). A positive correlation was found between E2 and Kmax (r = 0.222, P = 0.007) in male patients.ConclusionsConclusively, our results showed that T level was reduced in both female and male KC plasma, while E2 was increased in male KC plasma. Different levels of sex hormones are correlated with KC, which, may provide the basis of a new technique for screening and diagnosing KC with or without the assistance of current imaging techniques. Moreover, the correlations between sex hormone alterations and KC provide compelling insight into KC etiopathogenesis.

Introduction and AimsThe behavioral changes that arose from quarantine due to the COVID-19 pandemic may have impacted the weight of people. This study aims to investigate the incidence and predictors of weight gain during the quarantine period.MethodsAn online survey was performed five months after the social distance measures implementation. Participants recorded their current and usual weight before lockdown. A multivariate logistic regression model was performed.ResultsData on 1334 participants were evaluated (33.6y, 79.8% females), and 58.8% have gained weight (3.0 kg; 0.1 to 30.0 kg). Predictors of weight gain were increased food intake (OR = 5.40); snacking (OR = 2.86); fast food (OR = 1.11); canned products (OR = 1.08); and in physical activity (OR = 0.99) concerning the period before the pandemic; also time spent at work, including household chores (OR = 1.58); evening snack (OR = 1.54); higher frequency of alcoholic beverage intake (OR = 1.59) and dose of alcoholic beverage (OR = 1.11); uncontrolled eating (OR = 1.01), and vegetable intake (OR = 0.92) during the quarantine and physical activity before pandemic period (OR = 0.99).ConclusionMost participants have gained weight during the pandemic because of working changes, lifestyle, eating habits changes, and uncontrolled eating behavior. These results can be useful to encourage changes during future quarantine periods to prevent weight gain.

Published: February 2022

BackgroundPyroptosis is regulated by long non-coding RNAs (lncRNAs) in ovarian cancer (OC). Therefore, a comprehensive analysis of pyroptosis-related lncRNAs (PRLs) in OC is crucial for developing therapeutic strategies and survival prediction.MethodsBased on public database raw data, mutations in the landscape of pyroptosis-related genes (PRGs) in patients with OC were investigated thoroughly. PRLs were identified by calculating Pearson correlation coefficients. Cox and LASSO regression analyses were performed on PRLs to screen for lncRNAs participating in the risk signature. Furthermore, receiver operating characteristic (ROC) curves, Kaplan–Meier survival analyses, decision curve analysis (DCA) curves, and calibration curves were used to confirm the clinical benefits. To assess the ability of the risk signature to independently predict prognosis, it was included in a Cox regression analysis with clinicopathological parameters. Two nomograms were constructed to facilitate clinical application. In addition, potential biological functions of the risk signature were investigated using gene function annotation. Subsequently, immune-related landscapes and BRCA1/2 mutations were compared in different risk groups using diverse bioinformatics algorithms. Finally, we conducted a meta-analysis and in-vitro assays on alternative lncRNAs.ResultsA total of 374 patients with OC were randomized into training and validation cohorts (7:3). A total of 250 PRLs were selected from all the lncRNAs. Subsequently, a risk signature (DICER1-AS1, MIR600HG, AC083880.1, AC109322.1, AC007991.4, IL6R-AS1, AL365361.1, and AC022098.2) was constructed to distinguish the risk of patient survival. The ROC curve, K-M analysis, DCA curve, and calibration curve indicated excellent predictive performance for determining overall survival (OS) based on the risk signature in each cohort (p &lt; 0.05). The Cox regression analysis indicated that the risk signature was an independent prognostic factor for OS (p &lt; 0.05). Moreover, significant differences in the immune response and BRCA1 mutations were identified in different groups distinguished by the risk signature (p &lt; 0.05). Interestingly, in-vitro assays showed that an alternative lncRNA (DICER1-AS1) could promote OC cell proliferation.ConclusionThe PRL risk signature could independently predict overall survival and guide treatment in patients with OC.

PurposeIn radiotherapy, high radiation exposure to optic nerve (ON) can cause optic neuropathy or vision loss. In this study, we evaluated the pattern and extent of the ON movement using MRI, and investigated the potential dosimetric effect of this movement on radiotherapy.MethodsMRI was performed in multiple planes in 5 human subjects without optic pathway abnormalities to determine optic nerve motion in different scenarios. The subjects were requested to gaze toward five directions during MRI acquisitions, including neutral (straight forward), left/right (horizontal movement), and up/down (vertical movement). Subsequently, the measured displacement was applied to patients with peri-optic tumors to evaluate the potential dosimetric effect of this motion.ResultsThe motion of ON followed a nearly conical shape. By average, the anterior end of ONs moved with 10.8 ± 2.2 mm horizontally and 9.3 ± 0.8 mm vertically, while posterior end has negligible displacement. For patients who underwent stereotactic radiotherapy to a peri-optic tumors, the movement of ON in this measured range introduced non-negligible dosimetric effect.ConclusionThe range of motion of the anterior portions of the optic nerves is on the order of centimeters, which may need to be considered with extra attention during radiation therapy in treating peri-optic lesions.
