RESUMEN
BACKGROUND AND OBJECTIVE: Trigeminal Neuralgia (NT) is a common pathology in Neurosurgery. It can be classified as idiopathic or secondary to other pathologies, such as Multiple Sclerosis (MS). Several surgical treatments have been described, some of them being replaced by more modern techniques. Partial sensory rhizotomy (PSR), described by Dandy is a technique replaced by other techniques due to its permanent side effects. We present our experience with this technique in patients with recurrent NT. METHODS AND MATERIALS: A retrospective review is carried out on five patients who underwent surgery at our center from 2018 to 2023 using the PSR technique. RESULTS: All the patients intervened showed significant clinical improvement, except one patient who required reintervention due to uncontrolled pain. According to the Barrow Neurological Institute (BNI) scale, 80% (4/5) of patients showed improvement from grade V to grades I/II except for one of them. This patient suffered from MS. Additionally, one patient presented a corneal ulcer after surgery due to impairment of the corneal reflex. CONCLUSION: In our experience, PSR is a valid treatment option in selected patients with recurrent TN. It has a low incidence of complications with an adequate surgical technique and anatomical knowledge of the region. To the best of our knowledge, we are one of the few centers in Spain to publish our results with PSR in the last ten years. We report good results in pain control withdrawing medication in 80% (4/5) of the operated patients.

Introducción: La ecografía muscular es una herramienta válida para monitorizar la pérdida de masa muscular de personas críticamente enfermas. El nivel de experiencia es clave para la precisión de las mediciones. Objetivo: Evaluar la confiabilidad interobservador de evaluadores experimentados y novatos midiendo grosor y eco-intensidad del cuádriceps y tibial anterior. Métodos: Estudio observacional transversal. Participaron 24 kinesiólogos de cuidados críticos; 5 experimentados (> 4 años de experiencia ecográfica) y 19 novatos (sin experiencia previa, por lo que recibieron entrenamiento de 16 horas). De forma estandarizada, cada evaluador midió ecográficamente el grosor (centímetros) del cuádriceps y tibial anterior de 10 modelos sanos y jóvenes usando equipos portátiles (transductores lineales y convexos). Se calculó el Coeficiente de Correlación Intraclase y el Cambio Mínimo Detectable (95% intervalo de confianza). Además, los novatos calificaron la eco-intensidad de 19 ecografías musculares de personas críticamente enfermas con la escala Heckmatt (calificación visual cualitativa) y se midió el acuerdo con los experimentados (Spearman Rho). Resultados: Se realizaron 960 mediciones de grosor muscular (experimentados = 200 y novatos = 760). La media del grosor del cuádriceps y tibial anterior fue 4,4 ± 0,77 y 2,4 ± 0,35 centímetros para los experimentados y 4,2 ± 0,80 y 2,2 ± 0,39 centímetros para los novatos, respectivamente. La confiabilidad de cuádriceps y tibial anterior fue 0,82 y 0,86 para los experimentados y 0,76 y 0,41 para los novatos. El Cambio Mínimo Detectable osciló entre 0,14-0,33 centímetros. La puntuación media de Heckmatt fue 2,6 ± 0,83 puntos, con una confiabilidad de 0,68 y una concordancia con los experimentados de 0,78 [p < 0,001]. Conclusiones: La confiabilidad interobservador de los experimentados fue excelente y la de los novatos moderada a buena. El nivel de experiencia podría determinar los resultados de confiabilidad.
Background: Muscle ultrasound is a valid tool to monitor muscle mass loss in critically ill patients. The level of experience is essential to the accuracy of the measurements. Aim: To evaluate the interobserver reliability of experienced and novice raters measuring muscle thickness and echo intensity of the quadriceps and tibialis anterior. Material and Methods: Cross-sectional observational study. Twenty-four critical care physiotherapists participated (5 experienced and 19 novice). Following a standardized ultrasound protocol, each rater measured the thickness (centimeters) of the quadriceps and tibialis anterior of 10 healthy and young models using linear and convex probes of portable devices. The Intraclass Correlation Coefficient and the Minimal Detectable Change (95% confidence interval) were calculated. Additionally, the novices scored the echo intensity of 19 muscle ultrasound images of critically ill patients using the Heckmatt score (qualitative assessment). The agreement with experienced raters was evaluated (Spearman Rho). Results: 960 muscle thickness measurements were performed (experienced = 200 and novice = 760). The mean thickness of the quadriceps and tibialis anterior was 4.4 ± 0.77 and 2.4 ± 0.35 centimeters for the experienced and 4.2 ± 0.80 and 2.2 ± 0.39 centimeters for the novices, respectively. Quadriceps' and tibialis' anterior reliability were 0.82 and 0.86 for experienced and 0.76 and 0.41 for novices, respectively. The Minimal Detectable Change ranged from 0.14-0.33 centimeters. The mean Heckmatt score was 2.6 ± 0.83 points, with a reliability of 0.68 and an agreement with the experimenters of 0.78 [p < 0.001]. Conclusions: Interobserver reliability was excellent for experienced raters and moderate to good for novice raters. The level of experience could determine the reliability of the results.
RESUMEN
Even though it is widely held that the theory of evolution is one of the pillars of the biological sciences, as we begin the third decade of the twenty-first century, it is alarming how little we know about science, technology, engineering, and mathematics (STEM) majors and non-STEM majors' misconceptions about evolution in countries such as Brazil, Chile, Colombia, and Greece, to name a few. The situation is even more complicated if we acknowledge that contemporary educational approaches (e.g., student-centered learning) mean that students' misconceptions are one of the multiple aspects that influence the construction of meaningful learning. Here, we present a picture of Colombian STEM/non-STEM majors' misconceptions about evolution. Participants were 547 students from different STEM/non-STEM majors (278 females and 269 males, 16-24 years old). During 5 years (10 academic semesters), data were collected from students' responses to an 11-item questionnaire administered in a Colombian university. We hypothesized that the academic semester within these 5 years in which each student completed the instrument as well as respondents' age, gender, and/or major may influence their misconceptions about evolution. Results reveal that participants had a moderate understanding of evolution. Also, we found a limited understanding of microevolution among participants. Furthermore, cross-sectional analyses of differences in undergraduates' responses across demographic variables showed that despite apparent differences, these were not reliable since the differences were not statistically significant. Implications for evolution education are discussed.

BACKGROUND: Nursing home residences suffered a lockdown from the beginning of the COVID-19 pandemic. The present study prospectively evaluates the frailty, functional, and nutritional statuses of nursing home residents. METHODS: Three hundred and one residents from three nursing homes took part in the study. Frailty status was measured using the FRAIL scale. Functional status was evaluated using the Barthel Index. Additionally, Short Physical Performance Batter (SPPB), SARC-F, hand-grip strength, and gait speed were also evaluated. Nutritional status was determined using the mini nutritional assessment test (MNA) and several anthropometrical and biochemical markers. RESULTS: Mini Nutritional Assessment test scores decreased in 20% throughout the confinement (p < .001). Barthel index, SPPB and SARC-F scores also decreased, although to a lesser extent, reflecting a decrease in functional capacity. However, both anthropometric parameters, hand grip strength and gait speed, remained stable throughout confinement (p > .050 in all cases). Morning cortisol secretion significantly decreased by 40% from baseline to post-confinement. A significant reduction in daily cortisol variability was observed, which may suggest increased distress. Fifty-six residents died during the period of confinement (81.4% survival rate). Sex, FRAIL and Barthel Index scores were significant predictors of resident survival. CONCLUSION: After the first COVID-19 blockade, several alterations in residents' frailty markers were observed, which were small and potentially reversible. However, many of the residents were pre-frail after the lockdown. This fact highlights the need for preventive strategies to reduce the impact of future social and physical stressors on these vulnerable individuals.

Rhodnius prolixus is the most important vector of Trypanosoma cruzi in the northern part of South America. The compound eyes in adults of R. prolixus are involved in the nocturnal flight dispersion from sylvatic environments into human dwellings. During this behavior, the artificial lights play an important role in attracting R. prolixus; however, it is still not clear whether the compound eyes of this species use different visible wavelengths as a cue during active dispersion. We applied electrophysiological (electroretinography or ERG) and behavioral (take-off) experiments in a controlled laboratory setting to determine the spectral sensitivity of the compound eyes and the attraction of R. prolixus adults to discrete visible wavelengths. For the ERG experiments, flashes of 300 ms at wavelengths ranging between 350 and 700 nm at a constant intensity of 3.4 µW/cm2 were tested after adaptation to darkness and to blue and yellow lights. For the behavioral experiments, the adults were exposed to nine visible wavelengths at three different intensities, and their direction of take-off in an experimental arena was established with circular statistics. The ERG results showed peaks of spectral sensitivity at 470-490 nm and 520-550 nm in adults, while behavioral experiments showed attractions to blue, green and red lights, depending on the intensity of the light stimuli. The electrophysiological and behavioral results confirm that R. prolixus adults can detect certain wavelengths in the visible spectrum of light and be attracted to them during take-off.

BACKGROUND: Previous works have observed an increase of depression and other psychological disorders on nursing home residents as a consequence of coronavirus disease 2019 (COVID-19) lockdown; however, there are few studies that have performed a comprehensive evaluation of all people involved in nursing homes environment. The objective of the work was to analyse the impact of lockdown on psychosocial factors of nursing home residents, relatives and clinical staff and how these variables have influenced residents' survival. METHODS: A prospective study was designed. Evaluations were performed at three different times: a) at the beginning of Spanish confinement, in March 2020; b) just before the second wave of the pandemic, with relaxation of security measures but in lockdown, and c) in January-February 2021, at the end of the second wave, when visits were already allowed. The study was conducted on three different nursing homes. Three hundred and one residents, 119 clinical staff and 51 relatives took part in the study. Anxiety and depression were evaluated in all participants. A scale on the meaning of suffering was also performed. In addition, burnout status was also determined in the clinical staff. RESULTS: All participants showed lower depression during lockdown, while at the beginning and at the end of the confinement, these values were significantly increased. In residents, these changes were dependent of cognitive status (p = 0.012). Anxiety was significantly higher in residents. The evolution of anxiety was similar than with depression, with lower values during confinement, although clinical staff showed higher anxiety levels at the beginning. The feeling of suffering was significantly lower in the clinical staff than in resident and relative groups. Residents' survival was dependent of cognitive status (p = 0.018) and voluntary confinement (p < 0.001). CONCLUSIONS: During the first COVID-19 lockdown, psychological wellbeing of residents cared in nursing homes, their relatives and staff did not seem to be seriously affected. Previous mental health in relatives and staff together with a resilient approach to the adversity might partly be protecting factors. The lack of consequences on residents' anxiety, depression and perception of social support may reflect the special attention and care they received. Finally, as in the current study only data of the first two COVID-19 waves were analysed, its findings might be partly generalized to all the pandemic.

Biogeographic patterns in microorganisms are poorly understood, despite the importance of microbial communities for a range of ecosystem processes. Our knowledge of microbial ecology and biogeography is particularly deficient in rare and threatened ecosystems. We tested for three ecological patterns in microbial community composition within ephemeral wetlands-vernal pools-located across Baja California (Mexico) and California (USA): (1) habitat filtering; (2) a latitudinal diversity gradient; and (3) distance decay in community composition. Paired water and soil samples were collected along a latitudinal transect of vernal pools, and bacterial and archaeal communities were characterized using 16S rDNA sequencing. We identified two main microbial communities, with one community present in the soil matrix that included archaeal and bacterial soil taxa, and another community present in the overlying water that was dominated by common freshwater bacterial taxa. Aquatic microbial communities were more diverse in the north, and displayed a significant but inverted latitudinal diversity pattern. Aquatic communities also exhibited a significant distance-decay pattern, with geographic proximity, and precipitation explaining part of the community variation. Collectively these results indicate greater sensitivity to spatial and environmental variation in vernal pool aquatic microbial communities than in soil microbial communities. We conclude that vernal pool aquatic microbial communities can display distribution patterns similar to those exhibited by larger organisms, but differ in some key aspects, such as the latitudinal gradient in diversity.

Métodos estudio descriptivo, prospectivo, de serie de casos, que incluyó a pacientes que ingresaron con el diagnóstico de traumatismo torácico, en el servicio de Cirugía General del Hospital General Universitario Dr. Gustavo Aldereguía Lima, de Cienfuegos, en el período enero/2019 a diciembre/2020. Las variables analizadas fueron: edad, sexo, comorbilidades, exámenes imagenológicos, agente causal, lesión torácica, tipo de tratamiento, tipo de traumatismo torácico y estado al egreso. Resultados el trauma de tórax fue más frecuente en el sexo masculino, a partir de la cuarta década de vida en pacientes sanos. El examen imagenológico más usado fue la radiografía simple de tórax; y el agente causal predominante, la herida por arma blanca. Las lesiones torácicas más frecuentes resultaron el enfisema subcutáneo y el hemoneumotorax, así como la pleurostomía fue el tipo de tratamiento más usado. Predominó el traumatismo torácico aislado, siendo las lesiones abdominales las más asociadas. La mayoría de los pacientes egresaron vivos. Conclusión el trauma torácico constituye una patología altamente desafiante, por lo complejas que pueden llegar a ser las lesiones derivadas de él; se presenta con mayor frecuencia en hombres sanos. Cuando se asocia a otras lesiones aumenta la mortalidad.
Background chest trauma is a complex clinical picture that can compromise the patient's life. Therefore, its study and analysis is of interest. Objective to characterize patients with chest trauma in the General Surgery service. Methods descriptive, prospective, case series study which included patients admitted with a diagnosis of chest trauma, in the General Surgery Service at the Dr. Gustavo Aldereguía Lima General University Hospital, Cienfuegos, from January 2019 to December2020. The analyzed variables were: age, sex, comorbidities, imaging tests, causal agent, chest injury, type of treatment, type of chest trauma, and discharge status. Results chest trauma was more frequent in males, from the fourth decade of life in healthy patients. The most used imaging test was the simple chest X-ray; and the predominant causal agent, the stab wound. The most frequent chest injuries were subcutaneous emphysema and hemopneumothorax, and pleurostomy was the most used type of treatment. Isolated chest trauma prevailed, with abdominal injuries being the most associated. Most of the patients were discharged alive. Conclusion thoracic trauma constitutes a highly challenging pathology, due to how complex the injuries derived from it can become; It occurs more frequently in healthy men. When associated with other injuries, mortality increases.
RESUMEN
Inherited retinal dystrophies (IRDs) affect an estimated 1 in every 2000 people, this corresponding to nearly 2 million cases worldwide. Currently, 270 genes have been associated with IRDs, most of them altering the function of photoreceptors and retinal pigment epithelium. Gene therapy has been proposed as a potential tool for improving visual function in these patients. Clinical trials in animal models and humans have been successful in various types of IRDs. Recently, voretigene neparvovec (Luxturna®) has been approved by the US Food and Drug Administration for the treatment of biallelic mutations in the RPE65 gene. The current state of the art in gene therapy involves the delivery of various types of viral vectors into the subretinal space to effectively transduce diseased photoreceptors and retinal pigment epithelium. For this, subretinal injection is becoming increasingly popular among researchers and clinicians. To date, several approaches for subretinal injection have been described in the scientific literature, all of them effective in accessing the subretinal space. The growth and development of gene therapy give rise to the need for a standardized procedure for subretinal injection that ensures the efficacy and safety of this new approach to drug delivery. The goal of this review is to offer an insight into the current subretinal injection techniques and understand the key factors in the success of this procedure.
RESUMEN
(1) Objective: To determine the incidence, visual outcomes and risk factors associated with the recurrence of primary retinal detachment (RD) in a tertiary hospital. (2) Methods: A retrospective observational study was conducted, and data were collected on all eyes diagnosed with primary RD between January 2017 and December 2020. A detailed database was generated with data on anatomic and visual outcomes, and surgical technique information, for all the cases. (3) Results: 570 eyes with primary RD were included. Mean annual incidence of primary RD was 21.8 cases per 100,000 inhabitants. Mean follow-up time was 465 (±410.5) days. Mean time to redetachment was 114.4 (±215.8) days, with the median being 35 days. Statistically significant variables related to a higher risk of recurrence were: male sex (p = 0.04), type of tamponade (p = 0.01), surgeon (p = 0.035), inferonasal (p = 0.002) and inferotemporal (p = 0.032) involvement, complex RD (p < 0.001) and ocular comorbidity (p < 0.001). More satisfactory final visual acuity (VA) in patients not suffering redetachment was associated with shorter duration of central vision loss. (4) Conclusions: Sex, type of tamponade, inferior detachment, RD complexity, surgeon and ocular comorbidity were identified as prognostic factors for recurrence. Worse final postoperative VA was found in patients referring central vision loss for more than 4 days before surgery.
RESUMEN
OBJECTIVES: The large number of infected patients requiring mechanical ventilation has led to the postponement of scheduled neurosurgical procedures during the first wave of the COVID-19 pandemic. The aims of this study were to investigate the factors that influence the decision to postpone scheduled neurosurgical procedures and to evaluate the effect of the restriction in scheduled surgery adopted to deal with the first outbreak of the COVID-19 pandemic in Spain on the outcome of patients awaiting surgery. DESIGN: This was an observational retrospective study. SETTINGS: A tertiary-level multicentre study of neurosurgery activity between 1 March and 30 June 2020. PARTICIPANTS: A total of 680 patients awaiting any scheduled neurosurgical procedure were enrolled. 470 patients (69.1%) were awaiting surgery because of spine degenerative disease, 86 patients (12.6%) due to functional disorders, 58 patients (8.5%) due to brain or spine tumours, 25 patients (3.7%) due to cerebrospinal fluid (CSF) disorders and 17 patients (2.5%) due to cerebrovascular disease. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was mortality due to any reason and any deterioration of the specific neurosurgical condition. Second, we analysed the rate of confirmed SARS-CoV-2 infection. RESULTS: More than one-quarter of patients experienced clinical or radiological deterioration. The rate of worsening was higher among patients with functional (39.5%) or CSF disorders (40%). Two patients died (0.4%) during the waiting period, both because of a concurrent disease. We performed a multivariate logistic regression analysis to determine independent covariates associated with maintaining the surgical indication. We found that community SARS-CoV-2 incidence (OR=1.011, p<0.001), degenerative spine (OR=0.296, p=0.027) and expedited indications (OR=6.095, p<0.001) were independent factors for being operated on during the pandemic. CONCLUSIONS: Patients awaiting neurosurgery experienced significant collateral damage even when they were considered for scheduled procedures.

Technological advances in mechanical ventilation have been essential to increasing the survival rate in intensive care units. Usually, patients needing mechanical ventilation use controlled ventilation to override the patients respiratory muscles and favor lung protection. Weaning from mechanical ventilation implies a transition towards spontaneous breathing, mainly using assisted mechanical ventilation. In this transition, the challenge for clinicians is to avoid under and over assistance and minimize excessive respiratory effort and iatrogenic diaphragmatic and lung damage. Esophageal balloon monitoring allows objective measurements of respiratory muscle activity in real time, but there are still limitations to its routine application in intensive care unit patients using mechanical ventilation. Like the esophageal balloon, respiratory muscle electromyography and diaphragmatic ultrasound are minimally invasive tools requiring specific training that monitor respiratory muscle activity. Particularly during the coronavirus disease pandemic, non invasive tools available on mechanical ventilators to monitor respiratory drive, inspiratory effort, and work of breathing have been extended to individualize mechanical ventilation based on patients needs. This review aims to identify the conceptual definitions of respiratory drive, inspiratory effort, and work of breathing and to identify non invasive maneuvers available on intensive care ventilators to measure these parameters. The literature highlights that although respiratory drive, inspiratory effort, and work of breathing are intuitive concepts, even distinguished authors disagree on their definitions.

Technological advances in mechanical ventilation have been essential to increasing the survival rate in intensive care units. Usually, patients needing mechanical ventilation use controlled ventilation to override the patient's respiratory muscles and favor lung protection. Weaning from mechanical ventilation implies a transition towards spontaneous breathing, mainly using assisted mechanical ventilation. In this transition, the challenge for clinicians is to avoid under and over assistance and minimize excessive respiratory effort and iatrogenic diaphragmatic and lung damage. Esophageal balloon monitoring allows objective measurements of respiratory muscle activity in real time, but there are still limitations to its routine application in intensive care unit patients using mechanical ventilation. Like the esophageal balloon, respiratory muscle electromyography and diaphragmatic ultrasound are minimally invasive tools requiring specific training that monitor respiratory muscle activity. Particularly during the coronavirus disease pandemic, non invasive tools available on mechanical ventilators to monitor respiratory drive, inspiratory effort, and work of breathing have been extended to individualize mechanical ventilation based on patient's needs. This review aims to identify the conceptual definitions of respiratory drive, inspiratory effort, and work of breathing and to identify non invasive maneuvers available on intensive care ventilators to measure these parameters. The literature highlights that although respiratory drive, inspiratory effort, and work of breathing are intuitive concepts, even distinguished authors disagree on their definitions.
