Current status of robotic training during the urology residency: results from a national survey in Spain.

INTRODUCTION AND OBJECTIVES: The increasing number of robotic urological procedures observed in recent years highlights the need to expand training opportunities in robotic surgery. Our objective is to investigate the state of robotic training during urology residency in Spain in order to identify significant deficiencies. MATERIALS AND METHODS: A 20-item online survey was conducted among urology residents in Spain who were registered in the database of the Residents and Young Urologists Group of the Spanish Association of Urology. The survey assessed subjective opinions, institutional aspects, training resources, and experience regarding robotic surgery. A total of 455 email invitations were sent throughout the year 2021. Descriptive analysis of the responses was performed. RESULTS: The participation rate reached 30%, with a total of 135 residents. 52% of respondents lacked access to a robotic system in their institution, of which only 48% could compensate for this deficiency through external rotations. Among those with access to a robotic system, 25% and 23% reported having access to theoretical and practical training, respectively. The existence of a formal training program was low (13%). 85% of the respondents considered robotic surgery training in Spain to be deficient. CONCLUSIONS: Training for Spanish residents in robotic urological surgery is perceived as inadequate, emphasizing the crucial need for improvement in training programs in this field.

Natural and hybrid immunity after SARS-CoV-2 infection in children and adolescents.

PURPOSE: In contrast to adults, immune protection against SARS-CoV-2 in children and adolescents with natural or hybrid immunity is still poorly understood. The aim of this study was to analyze different immune compartments in different age groups and whether humoral immune reactions correlate with a cellular immune response. METHODS: 72 children and adolescents with a preceding SARS-CoV-2 infection were recruited. 37 were vaccinated with an RNA vaccine (BNT162b2). Humoral immunity was analyzed 3-26 months (median 10 months) after infection by measuring Spike protein (S), nucleocapsid (NCP), and neutralizing antibodies (nAB). Cellular immunity was analyzed using a SARS-CoV-2-specific interferon-γ release assay (IGRA). RESULTS: All children and adolescents had S antibodies; titers were higher in those with hybrid immunity (14,900 BAU/ml vs. 2118 BAU/ml). NCP antibodies were detectable in > 90%. Neutralizing antibodies (nAB) were more frequently detected (90%) with higher titers (1914 RLU) in adolescents with hybrid immunity than in children with natural immunity (62.5%, 476 RLU). Children with natural immunity were less likely to have reactive IGRAs (43.8%) than adolescents with hybrid immunity (85%). The amount of interferon-γ released by T cells was comparable in natural and hybrid immunity. CONCLUSION: Spike antibodies are the most reliable markers to monitor an immune reaction against SARS-CoV-2. High antibody titers of spike antibodies and nAB correlated with cellular immunity, a phenomenon found only in adolescents with hybrid immunity. Hybrid immunity is associated with markedly higher antibody titers and a higher probability of a cellular immune response than a natural immunity.

Live-cell three-dimensional single-molecule tracking reveals modulation of enhancer dynamics by NuRD.

To understand how the nucleosome remodeling and deacetylase (NuRD) complex regulates enhancers and enhancer-promoter interactions, we have developed an approach to segment and extract key biophysical parameters from live-cell three-dimensional single-molecule trajectories. Unexpectedly, this has revealed that NuRD binds to chromatin for minutes, decompacts chromatin structure and increases enhancer dynamics. We also uncovered a rare fast-diffusing state of enhancers and found that NuRD restricts the time spent in this state. Hi-C and Cut&Run experiments revealed that NuRD modulates enhancer-promoter interactions in active chromatin, allowing them to contact each other over longer distances. Furthermore, NuRD leads to a marked redistribution of CTCF and, in particular, cohesin. We propose that NuRD promotes a decondensed chromatin environment, where enhancers and promoters can contact each other over longer distances, and where the resetting of enhancer-promoter interactions brought about by the fast decondensed chromatin motions is reduced, leading to more stable, long-lived enhancer-promoter relationships.

Analysis of esthetic assessment scales in two surgical approaches for hypertrophic pyloric stenosis. / Evaluación de escalas de valoración estética en dos abordajes quirúrgicos para la estenosis hipertrófica de píloro.

INTRODUCTION: Hypertrophic pyloric stenosis (HPS) is a frequent pathology in neonates, with extramucosal pyloromyotomy being a healing surgery. It may be performed through a transverse subcostal incision (TSI) or a transumbilical incision (TUI). OBJECTIVE: To compare complications, operating times, hospital stay, and esthetic results between both techniques. MATERIALS AND METHODS: A retrospective, descriptive study of patients undergoing HPS surgery between January 2010 and January 2020 was carried out. Qualitative variables (sex and complications) were expressed as absolute frequency and percentage, whereas quantitative variables (age at surgery, operating time, hospital stay, and scar esthetic assessment scales: MVSS [Modified Vancouver Scar Scale] and P-SAS [Patient Scar Assessment Scale]) were expressed as median and interquartile range. RESULTS: 107 patients were analyzed: TSI (60.7%, n = 65) vs. TUI (39.3%, n = 42). Male patients: 89.2%, n = 58 vs. 83.3%, n = 35; age (days): 31 (24.5-39.5) vs. 34.5 (29.5-47.25); operating time (minutes): 41 (33.75-60) vs. 46 (38.5-60); and hospital stay (days): 2 (2-4) vs. 3 (2-3). Clavien-Dindo grade II complications were more frequent in the TUI Group (1.54%, n = 1 vs. 23.81%, n = 10; p <0.001), with most of them being wound infections. The opinion regarding the scar according to the MVSS scale was better in the TUI Group (1.5 [0-4] vs. 0 [0-2]; p = 0.022). No significant differences were found in the P-SAS scale (10 (6-18) vs. 6 (6-9); p = 0.060). CONCLUSIONS: TUI is preferred from an esthetic point of view, and even though surgical wound infections are more frequent, it is not associated with longer operating times, longer hospital stay, or severe complications.

INTRODUCCION: La estenosis hipertrófica de píloro (EHP) es una patología frecuente en neonatos donde la piloromiotomía extramucosa es una cirugía curativa. Puede realizarse a través de una incisión transversa subcostal (IT) o una incisión transumbilical (ITU). OBJETIVO: Comparar complicaciones, tiempo quirúrgico y de hospitalización y resultado estético entre ambas técnicas. MATERIAL Y METODOS: Estudio descriptivo retrospectivo en pacientes intervenidos de EHP entre enero 2010-2020. Variables cualitativas (sexo y complicaciones) expresadas mediante frecuencia absoluta y porcentaje; y cuantitativas (edad en cirugía, tiempo operatorio, días de hospitalización y escalas de estética de cicatrices: MVSS (Modified Vancouver Scar Scale) y P-SAS (Patient Scar Assessment Scale)) expresadas mediante mediana y rango intercuartílico. RESULTADOS: Se analizaron 107 pacientes: IT (60,7%, n = 65) vs. ITU (39,3%, n = 42): varones (89,2%, n = 58 vs. 83,3%, n = 35), días de vida (31 [24,5-39,5] vs. 34,5 [29,5-47,25]), tiempo quirúrgico (41 [33,75-60] vs. 46 [38,5-60] minutos) y días de hospitalización (2 [2-4] vs. 3 [2-3]). Las complicaciones Clavien-Dindo II fueron más frecuentes en el grupo ITU (1,54%, n = 1 vs. 23,81%, n = 10; p <0,001), siendo la mayoría infecciones de la herida. En el grupo ITU presentaban una mejor opinión sobre la cicatriz en la escala MVSS (1,5 [0-4] vs. 0 [0-2]; p = 0,022). La escala P-SAS no alcanzó diferencias significativas (10 [6-18] vs. 6 [6-9]; p = 0,060). CONCLUSIONES: La ITU es mejor aceptada a nivel estético y, aunque presenta más infecciones de herida quirúrgica, no precisa más tiempo quirúrgico o de ingreso, ni asocia complicaciones graves.

Testing an Adapted Auditory Verbal Learning Test Paradigm for fMRI to Lateralize Verbal Memory in Patients with Epilepsy.

BACKGROUND AND PURPOSE: fMRI is a noninvasive tool for predicting postsurgical deficits in candidates with pharmacoresistant temporal lobe epilepsy. We aimed to test an adapted paradigm of the Rey Auditory Verbal Learning Test to evaluate differences in memory laterality indexes between patients and healthy controls and its association with neuropsychological scores. MATERIALS AND METHODS: We performed a prospective study of 50 patients with temporal lobe epilepsy and 22 healthy controls. Participants underwent a block design language and memory fMRI. Laterality indexes and the hippocampal anterior-posterior index were calculated. Language and memory lateralization was organized into typical and atypical on the basis of laterality indexes. A neuropsychological assessment was performed with a median time from fMRI of 8 months and was compared with fMRI performance. RESULTS: We studied 40 patients with left temporal lobe epilepsy and 10 with right temporal lobe epilepsy. Typical language occurred in 65.3% of patients and 90.9% of healthy controls (P = .04). The memory fMRI laterality index was obtained in all healthy controls and 92% of patients. The verbal memory laterality index was bilateral (24.3%) more frequently than the language laterality index (7.69%) in patients with left temporal lobe epilepsy. Atypical verbal memory was greater in patients with left temporal lobe epilepsy (56.8%) than in healthy controls (36.4%), and the proportion of bilateral laterality indexes (53.3%) was larger than right laterality indexes (46.7%). Atypical verbal memory might be associated with higher cognitive scores in patients. No relevant differences were seen in the hippocampal anterior-posterior index according to memory impairment. CONCLUSIONS: The adapted Rey Auditory Verbal Learning Test paradigm fMRI might support verbal memory lateralization. Temporal lobe epilepsy laterality influences hippocampal memory laterality indexes. Left temporal lobe epilepsy has shown a higher proportion of atypical verbal memory compared with language, potentially to memory functional reorganization.

Clinical landscape of LAG-3-targeted therapy.

Lymphocyte-activated gene 3 (LAG-3) is a cell surface inhibitory receptor and a key regulator of immune homeostasis with multiple biological activities related to T-cell functions. LAG-3 is considered a next-generation immune checkpoint of clinical importance, right next to programmed cell death protein 1 (PD-1) and cytotoxic T-cell lymphocyte antigen-4 (CTLA-4). Indeed, it is the third inhibitory receptor to be exploited in human anticancer immunotherapies. Several LAG-3-antagonistic immunotherapies are being evaluated at various stages of preclinical and clinical development. In addition, combination therapies blocking LAG-3 together with other immune checkpoints are also being evaluated at preclinical and clinical levels. Indeed, the co-blockade of LAG-3 with PD-1 is demonstrating encouraging results. A new generation of bispecific PD-1/LAG-3-blocking agents have also shown strong capacities to specifically target PD-1+ LAG-3+ highly dysfunctional T cells and enhance their proliferation and effector activities. Here we identify and classify preclinical and clinical trials conducted involving LAG-3 as a target through an extensive bibliographic research. The current understanding of LAG-3 clinical applications is summarized, and most of the publically available data up to date regarding LAG-3-targeted therapy preclinical and clinical research and development are reviewed and discussed.

Evolution of size-segregated aerosol concentration in NW Spain: A two-step classification to identify new particle formation events.

Real-time measurements of particles in the 15-736 nm range have been obtained by a Scanning Mobility Particle Sizer to characterize the evolution of particle size distribution and new particle formation (NPF) events in an urban background area. The annual, weekly and diurnal variations of the modal (nucleation (Nnuc), Aitken (NAit) and accumulation (Nacc)) particle concentrations were characterised. The NAit and Nacc registered their maximums in cold months during rush hours, in the morning (0600-0900 UTC) and in the afternoon (1700-2000 UTC), while the maximums for Nnuc were reached in warm months during midday hours. NAit, Nacc and Ntotal showed a significant negative correlation with wind speed and a different relationship with the planetary boundary layer (PBL) height by periods. In the warm period, a positive significant correlation between PBL and Nnuc was registered, indicating that the higher dispersion promoted by a high PBL causes favourable conditions for the occurrence of NPF events (a low polluted atmosphere). NPF processes are one of the main sources of ultrafine particles (<100 nm) in the warm period. After a visual-based classification, 45 NPF events of type Ia (strong and with a good confidence level) were identified and analysed, occurring primarily between 1100 and 1500 UTC, mainly in spring and summer. In addition, a two-step method was developed for identifying NPF events: cluster analysis followed by discriminant analysis. The application of discriminant analysis to one of the clusters, grouping 93 days, enabled us to identify 55 of the 56 NPF events days included in the cluster. This method is a valuable tool for identifying NPF events quickly and effectively.

Cellular Toxicity Mechanisms and the Role of Autophagy in Pt(IV) Prodrug-Loaded Ultrasmall Iron Oxide Nanoparticles Used for Enhanced Drug Delivery.

Ultrasmall iron oxide nanoparticles (<10 nm) were loaded with cis-diamminetetrachloroplatinum (IV), a cisplatin (II) prodrug, and used as an efficient nanodelivery system in cell models. To gain further insight into their behavior in ovarian cancer cells, the level of cellular incorporation as well as the platination of mitochondrial and nuclear DNA were measured using inductively coupled plasma mass spectrometry (ICP-MS) strategies. Quantitative Pt results revealed that after 24 h exposure to 20 µM Pt in the form of the Pt(IV)-loaded nanoparticles, approximately 10% of the incorporated Pt was associated with nuclear DNA. This concentration increased up to 60% when cells were left to stand in drug-free media for 3 h. These results indicated that the intracellular reducing conditions permitted the slow release of cisplatin (II) from the cisplatin (IV)-loaded nanoparticles. Similar results were obtained for the platination of mitochondrial DNA, which reached levels up to 17,400 ± 75 ng Pt/ mg DNA when cells were left in drug-free media for 3 h, proving that this organelle was also a target for the action of the released cisplatin (II). The time-dependent formation of Pt-DNA adducts could be correlated with the time-dependent decrease in cell viability. Such a decrease in cell viability was correlated with the induction of apoptosis as the main route of cell death. The formation of autophagosomes, although observed upon exposure in treated cells, does not seem to have played an important role as a means for cells to overcome nanoparticles' toxicity. Thus, the designed nanosystem demonstrated high cellular penetration and the "in situ" production of the intracellularly active cisplatin (II), which is able to induce cell death, in a sustained manner.

Sleep duration, physical activity, and caloric intake are related to weight status in Mexican American children: a longitudinal analysis.

BACKGROUND: Obesity is a serious issue, spanning all ages, and, in the U.S., disproportionately affects Latinos and African Americans. Understanding sleep, physical activity and dietary behaviors that may predict childhood obesity can help identify behavioral intervention targets. METHODS: Data were drawn from a U.S. cohort study of 323 Mexican American 8-10-year-old children and their mothers, who participated in a longitudinal study over a 2-year period. Measures were collected at baseline (BL; child mean age = 8.87, SD = 0.83), year 1 (FU1) and year 2 (FU2). Mothers reported on household income and acculturation at BL. Child height and weight were collected and BMI z-scores (BMIz) were calculated for weight status at BL, FU1, and FU2. Accelerometer-estimated sleep duration (hours) and moderate-to-vigorous physical activity (MVPA; minutes) were collected across 3 days at BL, FU1, and FU2. Two 24-h dietary recalls were performed at each time point; from these, average energy intake (EI, kcals/day) was estimated. Cross-lagged panel analysis was used to examine behavioral predictors on BMIz at each time point and across time. RESULTS: At BL and FU1, longer sleep duration (ß = - 0.22, p < 0.001; ß = - 0.17, p < 0.05, respectively) and greater MVPA (ß = - 0.13, p < 0.05; ß = - 0.20, p < 0.01, respectively) were concurrently related to lower BMIz. At FU2, longer sleep duration (ß = - 0.18, p < 0.01) was concurrently related to lower BMIz, whereas greater EI (ß = 0.16, p < 0.01) was related to higher BMIz. Longer sleep duration at BL predicted lower BMIz at FU1 (ß = - 0.05, p < 0.01). CONCLUSIONS: Longer sleep duration was concurrently related to lower weight status at each time point from ages 8-10 to 10-12. Higher MVPA was concurrently related to lower weight status in earlier childhood (ages 8-10 and 9-11) and higher EI was concurrently related to higher weight status toward the end of childhood (ages 10-12 years). Furthermore, longer sleep in earlier childhood was protective of children's lower weight status 1 year later. These findings suggest that sleep duration plays a consistent and protective role against childhood obesity; in addition, MVPA and healthy EI remain important independent factors for obtaining a healthy weight.

Scavenging of submicron aerosol particles in a suburban atmosphere: The raindrop size factor.

This paper studies the below-cloud scavenging caused by precipitation on ultrafine and accumulation modes, as well as the role of the different raindrop sizes in an urban environment. The equipment used to measure aerosol particles and raindrop variables includes a scanning mobility particle sizer spectrometer-SMPS and a Laser Precipitation Monitor (LPM), respectively. An analysis of the scavenging efficiency and the scavenging coefficient (λ) by modes and rain intensities was carried out. The main results observed have been: i) the nucleation (between 14 and 30 nm), Aitken (between 30 and 100 nm), accumulation 1 (between 100 and 300) and accumulation 2 (between 300 and 1000 nm) modes presented a scavenging efficiency of 15, 4, 22 and 21%, respectively; ii) events with rain intensities between 1 and 3 mm h-1 caused less scavenging in all modes; iii) raindrop sizes between 1.25 and 3.5 mm scavenged mainly particle sizes between 70 and 250 nm. Lower scavenging was observed on particle sizes >300 nm, and particle sizes >600 nm were only scavenged by raindrop sizes >4.75 mm; iv) the respirable fraction before and after the rain events presented a statically significant decrease of -35%. The combination in this study of SMPS and disdrometer measurements has resulted in a more detailed characterization of the influence of this process on the submicrometer aerosol fraction, noting that below-cloud scavenging is one of the main removal pathways for submicrometer aerosol particles. This study thus contributes to improving the current state of knowledge of below-cloud scavenging.

Percutaneous radiofrequency for the treatment of small renal masses: Analysis of outcomes and complications after 10 years of experience. / Radiofrecuencia percutánea en el tratamiento de masas renales pequeñas: análisis de resultados y complicaciones tras diez años de experiencia.

INTRODUCTION AND OBJECTIVE: The management of renal tumors ≤ 4 cm in elderly population or patients with comorbidities is a challenge, for which ablative therapies are an interesting alternative. The objective is to evaluate in our center the role of percutaneous radiofrequency in the treatment of small renal masses, the associated complications and the results obtained. MATERIAL AND METHODS: Retrospective evaluation of the radiofrequency treatments carried out between April 2010 and April 2020 in our center. Demographic data, associated comorbidities, tumor characteristics, complications and oncological and functional outcomes were reviewed. RESULTS: Fifty-seven tumors were treated in 53 patients. Mean follow-up of 48.2 months. The percentage of complete ablations obtained was of 89.5%. There were 19.3% of complications. According to Clavien-Dindo and SIR classification systems, 3.5% and 5.3% were major complications. A statistically significant association was found between the initial result of ablation and age (p = 0.047), RENAL-m (p = 0.044), the presence of cystic component (p = 0.049) and tumor size (p = 0.01). The cut-off point for size was established at 25 mm (p = 0.012). In multivariate analysis, only size remained as a predictor of initial ablation result (p = 0.01; OR 1.183; CI 95% 1.041-1.345). Cancer-specific survival and 5-year recurrence-free survival were 98.1% and 89.5%, respectively. A mean decrease of MDRD-4 of 6.59 mL/min (p = 0.005) was observed in the first six months after RFA. CONCLUSIONS: Given the excellent oncological and functional results demonstrated, ultrasound-guided percutaneous radiofrequency ablation is an effective and safe treatment for small renal masses in selected patients.

The effect of oblique-angle sputtering on large area deposition: a unidirectional ultrathin Au plasmonic film growth design.

Growing ultrathin nanogranular (NG) metallic films with continuously varying thickness is of great interest for studying regions of criticality and scaling behaviors in the vicinity of quantum phase transitions. In the present work, an ultrathin gold plasmonic NG film was grown on a sapphire substrate by RF magnetron sputtering with an intentional deposition gradient to create a linearly variable thickness ranging from 5 to 13 nm. The aim is to accurately study the electronic phase transition from the quantum tunneling regime to the metallic conduction one. The film structural characterization was performed by means of high-resolution transmission electron microscopy, atomic force microscopy, as well as x-ray diffraction and reflectivity techniques, which indicate the Volmer-Weber film growth mode. The optical and electrical measurements show a transition from dielectric-isolated gold NPs towards a continuous metallic network when t becomes larger than a critical value of tM = 7.8 nm. Our results show that the onset of the percolation region occurs when a localized surface plasma resonance transforms to display a Drude component, indicative of free charge carriers. We demonstrate that, by using a continuously varying thickness, criteria for metallicity can be unambiguously identified. The onset of metallicity is clearly distinguished by the Drude damping factor and by discontinuities in the plasma frequencies as functions of thickness.

Ustekinumab treatment for moderate to severe psoriasis. Eight-year real-world follow-up of 61 cases in a tertiary level hospital.

Background: Efficacy and safety profiles of ustekinumab have been proved in numerous clinical trials. However, relevant variations with daily practice have been shown and few studies value the long-term response maintenance.Objective: To evaluate the efficacy of long-term ustekinumab therapy in patients with moderate-to-severe plaque-type psoriasis in a real-world setting.Methods: Observational retrospective follow-up study including, patients receiving ustekinumab at least 3 months in our department. Efficacy was expressed as percentage of patients achieving Psoriasis area and severity index (PASI) 50, PASI75, and PASI90 and maintaining PASI ≤5, ≤3, and 0 every 3 months during the first year of treatment, and every 12 months to the end of follow-up or to withdrawal from the study.Results: Sixty-one patients. Fifty patients had previously been treated with other biologic therapies. The percentage of patients maintaining PASI90 was 72.1, 78.3, 70.0, 83.3, 96.2, 91.7, and 100.0%, and PASI value maintained 0 in 68.9, 73.9, 67.50, 80.6, 96.2, 91.7, and 100.0% at 3, 12, 24, 36, 60, 84, and 96 months. Ustekinumab was discontinued in 26.2% of patients. No patients were withdrawn because of adverse events.Conclusions: This real world-setting study shows maintenance of long-term efficacy and safety of ustekinumab treatment in moderate-severe plaque psoriasis in daily practice through 8 years.

How to interpret images in epileptic seizures: correlation between clinical and functional MRI findings. / Crisis epiléptica: ¿cómo interpretar la imagen? Correlación clínica-funcional.

Neuroimaging studies are essential in patients with epilepsy, both for diagnosis and surgical management. This article focuses on adult epileptic patients, reviewing the updated clinical criteria published by the International League Against Epilepsy for the definitions of seizures, epilepsy, and status epilepticus. It also describes the different types of epilepsy, the different presentations, the signs, the radiologic approach to managing seizures, and the differences between generalized and focal seizures. Finally, it discusses the relations between possible functional cerebral deficits secondary to potentially epileptogenic lesions and epilepsy surgery, underlining the importance of functional magnetic resonance imaging studies.

Efficacy of a topical combination of fipronil-permethrin against Rhodnius prolixus on dogs.

A controlled clinical trial was carried out to assess the mortality and repellency of a new topical combination of fipronil-permethrin (Effitix® Virbac, Mexico) against Rhodnius prolixus in dogs. Ten medium-size dogs (10-15 kg) with short hair were used. The dogs were exposed to 8 adult triatomines once weekly for 7 weeks. On the control day (D0), the dogs were exposed to the insects without treatment. On D7, the dogs were immediately treated with a spot-on 2.2 ml pipette containing 134 mg of fipronil and 1200 mg permethrin after exposure to the insects. The dose was repeated after 4 weeks following the manufacturer's instructions. Repellency at D0 was, 0 % and the insects had a high blood content. After 12 h post-contact, repellency was 86.3 % and slowly decrease though D21 and D28. On D7, none of the insects survived after 3 h of feeding on the treated dogs. On D14, D35 and D42, all insects died within 12 h post-feeding, whereas no mortality was observed in the control D0 (P < 0.05). The results of this study indicated that administration of the product following the manufacturer's instructions was efficacious at inducing rapid mortality of R. prolixus and therefore could be useful to prevent the transmission of American trypanosomiasis in dogs.
