Host-plant sex and phenology of Buddleja cordata Kunth interact to influence arthropod communities.

Intraspecific variation in plants is expected to have profound impacts on the arthropod communities associated with them. Because sexual dimorphism in plants is expected to provide consistent variation among individuals of the same species, researchers have often studied the effect it has on associated arthropods. Nevertheless, most studies have focused on the effect of sexual dimorphism in a single or a few herbivores, thus overlooking the potential effects on the whole arthropod community. Our main objective was to evaluate effects of Buddleja cordata's plant-sex on its associated arthropod community. We surveyed 13 pairs of male and female plants every 2 months during a year (June 2010 to April 2011). Every sampling date, we measured plant traits (water content and leaf thickness), herbivory, and the arthropod community. We did not find differences in herbivory between plant sex or through time. However, we found differences in water content through time, with leaf water-content matching the environmental seasonality. For arthropod richness, we found 68 morphospecies associated with female and 72 with male plants, from which 53 were shared by both sexes. We did not observe differences in morphospecies richness; however, we found sex-associated differences in the diversity of all species and differences on the diversity of the most abundant species with an interesting temporal component. During peak flowering season, male plants showed higher values on both parameters, but during the peak fructification season female plants showed the higher values on both diversity parameters. Our research exemplifies the interaction between plant-phenology and plant-sex as drivers of arthropod communities' diversity, even when plant sexual-dimorphism is inconspicuous, and highlighting the importance of accounting for seasonal variation. We stress the need of conducting more studies that test this time-dependent framework in other dioecious systems, as it has the potential to reconcile previous contrasting observations reported in the literature.

Controversies in point-of-care 3D printing for oncological and reconstructive surgery with free software in oral and maxillofacial surgery: European regulations, costs, and timeframe.

The aim of this paper is to discuss the controversies surrounding the most recent European regulations, as well as the cost, for a 3D printing workflow using free-source software in the context of a tertiary level university hospital in the Spanish public health system. Computer-aided design and manufacturing (CAD/CAM) for head and neck oncological surgery with the printing of biomodels, cutting guides, and patient-specific implants has made it possible to simplify and make this type of highly complex surgery more predictable. This technology is not without drawbacks, such as increased costs and the lead times when planning with the biomedical industry. A review of the current European legislation and the literature on this subject was performed, and comparisons made with the authors' in-house 3D printing setup using free software and different 3D printers. The cost analysis revealed that for the cheapest setup with free software, it would be possible to amortize the investment from case 2, and in all cases the initial investment would be amortized before case 9. The timeframe ranged from 2 weeks with the biomedical industry to 72 h with point-of-care 3D printing. It is now possible to develop point-of-care 3D printing in any hospital with almost any budget.

Marine debris and associated organic pollutants in surface waters of Chiloé in the Northern Chilean Patagonia (42°-44°S).

We report the occurrence of plastics and associated persistent organic pollutants (POPs) in surface waters from Northern Chilean Patagonia. A total of 200 particles were found during the conducted survey. The highest number of particles found was 0.6 item m-3. We found that 53 % of the collected particles corresponded to plastic, with an average of 0.19 ± 0.18 item m-3. Microplastics (68 %) were the dominant size found in the area, followed by macroplastics (18 %) and mesoplastics (14 %). Most plastic particles were white (55 %) while others were <10 % each. Black and light blue represented 9 %; red, dark blue, and other colors 7 %; and green 6 %. Fragments were the most frequent shape of plastic debris (38 %), followed by Styrofoam (30 %) and fiber (27 %). Higher PBDE levels were found in the central zone, and those were higher than DDT, PeCB, HCB, and PCB levels. This study is the first report on POP occurrence in marine plastic debris from Chiloé Sea in the Northern Chilean Patagonia.

Ensayo clínico comparando el uso de tornillos y del sistema TighRope® Knotless en el tratamiento de las lesiones agudas de la sindesmosis / A randomized clinical trial comparing screws and the TighRope® Knotless system in the treatment of acute injuries of syndesmosis

Antecedentes y objetivo: Clásicamente el tratamiento de las lesiones agudas de la sindesmosis se ha realizado mediante tornillos. Hace unos años aparecieron implantes más flexibles que han evolucionado hasta el moderno TighRope® Knotless. El objetivo del presente estudio es comparar los resultados de ambos implantes. Material y métodos: Desde abril de 2019 hasta septiembre de 2020 reclutamos 68 pacientes diagnosticados de lesión aguda de la sindesmosis que fueron aleatorizados para tratamiento quirúrgico con tornillo o con TighRope® Knotless. Realizamos control posquirúrgico con tomografía axial computarizada, y a los 3, 6 y 12 meses se recogieron datos del rango articular, valores de escalas funcionales y se realizaron estudios de radiología simple. Resultados: Los pacientes tratados con tornillos no presentaban diferencias estadísticamente significativas en la escala AOFAS frente al grupo tratado con TighRope® Knotless a los 3 meses (83,1 vs. 81,80; p=1,03), ni a los 6 meses (88,27 vs. 88; p=0,26) ni a los 12 meses (93,03 vs. 92,10; p=0,93). Igualmente recogimos resultados similares en la escala de Olerud-Molander a los 3 meses (65 vs. 61,50; p=3,5), 6 meses (82,33 vs. 80,67; p=1,67) y 12 meses (92,67 vs. 90; p=2,67). Tampoco hubo diferencias en la tasa de malreducción posquirúrgica (ningún caso en ambos grupos), pérdida de reducción (3 en el grupo tratado con tornillo frente a 4 del grupo del TighRope® Knotless, p=0,54) o complicaciones (p=1). Conclusiones: El tratamiento de las lesiones agudas de la sindesmosis con tornillos o con TighRope® Knotless es similar tanto en resultados clínicos como radiológicos.(AU)

Background and aim: Classically acute syndesmosis injuries have been treated using screws. A few years ago more flexible implants appeared evolving to current TighRope® Knotless. The primary aim of this study is to compare clinical and radiographic outcome of both implants. Material and methods: From April 2019 to September 2020 68 patients diagnosed with acute syndesmosis injury were randomized to use screws or TighRope® Knotless. Syndesmosis reduction was assessed using bilateral CT potsoperatively. Outcomes were clinically and radiologically assessed at three, six, and twelve months after surgery. Results: No significant differences were identified in the AOFAS Scale between groups at three months (83.1 vs. 81.80; P=1.03), nor at six (88.27 vs. 88; P=.26) or at twelve (93.03 vs. 92.10; P=,93). There were also no differences in Olerud-Molander scale at three (65 vs. 61.50; P=3.5), six (82.33 vs. 80.67; P=1.67) and twelve months (92.67 vs. 90; P=2.67). Likewise, there were no differences in rate of postoperative malreduction (no cases in both groups), loss of reduction (three cases in screw group vs. four in TighRope® Knotless group, P=.54) or complications (P=1). Conclusions: Treatment of acute syndesmosis injuries with screws or the TighRope® Knotless implant is similar in both clinical and radiological results.(AU)

Linfadenectomía inguinal videoendoscópica modificada por abordaje suprafascial: descripción de la técnica y resultados quirúrgicos preliminares / Modified videoendoscopic inguinal lymphadenectomy through suprafascial approach: Technical description and preliminary surgical outcomes

Introducción: La disección de los ganglios linfáticos inguinales mediante abordaje videoendoscópico (LIVE) se ha planteado como una alternativa óptima para disminuir la morbilidad y mantener un control oncológico equivalente al del abordaje convencional. Uno de los pasos de mayor complejidad de la técnica es la elaboración de un plano de disección adecuado y entre sus ventajas está una exposición mejorada del campo quirúrgico. El objetivo de este estudio es determinar la viabilidad, en términos de seguridad y control oncológico, de una modificación de la técnica LIVE convencional, utilizando un plano de disección suprafascial, en una serie inicial de pacientes.Pacientes y métodos: Se llevó a cabo una revisión retrospectiva en un único centro de los pacientes tratados con LIVE mediante nuestra modificación de abordaje suprafascial. Se proporciona una descripción de la técnica quirúrgica paso a paso. Los datos recogidos incluyeron las características demográficas y de la enfermedad, las comorbilidades y los factores intra- y postoperatorios.Resultados: Se incluyó a un total de 7 pacientes (12 procedimientos). La edad media era de 64,42 años y el 71,42% de los pacientes eran hombres. El procedimiento se realizó de forma bilateral en el 71,4% de los casos. La mediana de pérdida de sangre estimada fue de 10mL (rango 10-25). El tiempo quirúrgico medio fue de 115 min (rango 120-170). La mediana del número de ganglios linfáticos obtenidos fue de 10,25 ganglios (rango 7-11). Solo un paciente (8,3%) experimentó una complicación de grado iiia de Clavien-Dindo, lo que requirió recambio del drenaje percutáneo. La mediana de tiempo hasta la retirada del drenaje fue de 13 días (rango 10-16). La mediana de duración de la estancia hospitalaria fue de 48 h, oscilando entre 24 y 96 h en toda la serie. (AU)

Introduction: The videoendoscopic approach to inguinal lymph node dissection (VEIL) has been suggested as an excellent alternative carrying lower morbidity but equivalent oncological control. One of its most difficult steps is the development of an appropriate plane of dissection. A suprafascial approach would allow for better exposure. The objective of this study is to determine the feasibility, in terms of safety and oncological control, of a technical modification to the classical VEIL technique using a suprafascial plane of dissection in an initial series of patients.Patients and methods: A single institution retrospective review of patients undergoing VEIL technique using our modified suprafascial approach was conducted. A step-by-step surgical description is provided. Data collected included demographics; comorbid conditions; disease characteristics; intraoperative factors; and postoperative factors.Results: A total of 7 patients (12 procedures) were included. Average age was 64.42 years old, and 71.42% of the patients were male. The procedure was performed bilaterally in 71.4% of the cases. Median estimated blood loss was 10mL (range 10-25). Mean operative time was 115 minutes (range 120-170). Median number of nodes removed was 10.25 (range 7-11). Only one of the patients (8.3%) experienced a Clavien-Dindo grade IIIa complication requiring delayed percutaneous drainage replacement. Median time until drainage removal was 13 days (range 10-16). Median length of stay was 48hours but ranged from 24-96hours within the series.Conclusions: The modified Video Endoscopic Inguinal Lymphadenectomy (VEIL) technique using a suprafascial plane of the dissection, allows a bilateral ILND in highly competitive operative times and with limited morbidity, without compromising its oncological efficacy.

Osimertinib and anti-HER3 combination therapy engages immune dependent tumor toxicity via STING activation in trans.

Over the past decade, immunotherapy delivered novel treatments for many cancer types. However, lung cancer still leads cancer mortality, and non-small-cell lung carcinoma patients with mutant EGFR cannot benefit from checkpoint inhibitors due to toxicity, relying only on palliative chemotherapy and the third-generation tyrosine kinase inhibitor (TKI) osimertinib. This new drug extends lifespan by 9-months vs. second-generation TKIs, but unfortunately, cancers relapse due to resistance mechanisms and the lack of antitumor immune responses. Here we explored the combination of osimertinib with anti-HER3 monoclonal antibodies and observed that the immune system contributed to eliminate tumor cells in mice and co-culture experiments using bone marrow-derived macrophages and human PBMCs. Osimertinib led to apoptosis of tumors but simultaneously, it triggered inositol-requiring-enzyme (IRE1α)-dependent HER3 upregulation, increased macrophage infiltration, and activated cGAS in cancer cells to produce cGAMP (detected by a lentivirally transduced STING activity biosensor), transactivating STING in macrophages. We sought to target osimertinib-induced HER3 upregulation with monoclonal antibodies, which engaged Fc receptor-dependent tumor elimination by macrophages, and STING agonists enhanced macrophage-mediated tumor elimination further. Thus, by engaging a tumor non-autonomous mechanism involving cGAS-STING and innate immunity, the combination of osimertinib and anti-HER3 antibodies could improve the limited therapeutic and stratification options for advanced stage lung cancer patients with mutant EGFR.

Hypofractionated whole breast irradiation after IORT treatment is safe in patients receiving adjuvant chemotherapy

Introduction Hypofractionated whole breast irradiation (hWBI) and intraoperative radiotherapy (IORT) could be associated in breast cancer patients showing high-risk factors of local recurrence after breast conserving therapy (BSC). The aim of this trial was to evaluate, for the first time, the toxicity and cosmesis of hWBI after photon-IORT in high-risk patients treated by adjuvant chemotherapy. Materials and methods Thirty-one high-risk localized breast cancer patients treated by BCS, IORT (20 Gy), and adjuvant chemotherapy were included from February 2019 to August 2020 in this prospective trial, of hWBI (40.5 Gy/2.67 Gy/15 fractions). Acute and late toxicity (CTCAEv5.0) and cosmesis (Harvard scale), were assessed after treatment. Results All patients completed their treatment and were evaluable after treatment. No patients showed severe (G3) acute/late toxicity. Excellent/good cosmesis at least 6 months after completing the treatment, was present in 93.6% of the patients. Conclusion hWBI in high-risk localized breast cancer patients treated by chemotherapy seems to have similar toxicity and cosmetic results than conventionally fractionated WBI in combination to photon-IORT after BCS (AU)

Calidad asistencial de la psicología clínica en el Servicio Andaluz de Salud evaluada por los facultativos / Quality of care of Clinical Psychology in the Andalusian Health Service as assessed by professionals

Objetivo: evaluación de la calidad asistencial de los servicios de psicología clínica en el Servicio Andaluz de Salud (SAS) desde la perspectiva de los/as facultativos/as. Método: investigación descriptiva; se elaboró un cuestionario de 39 ítems que evalúa diferentes dimensiones de la calidad asistencial (prevención, accesibilidad, idoneidad de intervenciones de evaluación y tratamiento, seguridad, y coordinación); han participado 83 facultativos/as especialistas de psicología clínica del SAS, lo que supone un 32’17% de la población de referencia en el momento de la recogida de datos.Resultados:la calidad asistencial actual de las prestaciones de psicología clínica en el SAS, partiendo de una ratio de 3,05 facultativos por cada100.000 habitantes, es deficiente, sobre todo en las variables de prevención, intensidad de las intervenciones de tratamiento y seguridad, y especialmente preocupante en los dispositivos del segundo nivel asistencial.Conclusiones: es urgente aumentar el número de profesionales especialistas en psicología clínica por cada 100.000 habitantes para reducir el riesgo que supone para los usuarios la deficiente intensidad con que se practican los tratamientos psicológicos; asimismo, es necesario establecer estándares de la carga de trabajo de los psicólogos clínicos para poder ofrecer una calidad asistencial adecuada, e integrar indicadores medibles de calidad en los sistemas de información de salud mental (AU)

Objective: Evaluation of healthcare quality of clinical psychology services in the Andalusian Health Service (SAS) from the perspective of the facultative. Method: Descriptive research. For data collection, a 39-item questionnaire was developed that assesses various dimensions of quality (prevention, accessibility, suitability of evaluation and treatment interventions, safety, and care coordination). A sample of 83 clinical psychologists responded to the questionnaire, representing 32.17% of the reference population, 258 facultative who, at the time of data collection make up the SAS staff. Results: The current quality of care of clinical psychology services in the SAS, based on a ratio of 3.05 clinical psychologists per 100,000 inhabitants, is deficient, especially in the dimensions of prevention, intensity of treatment interventions, and safety, and worrisome in the 2nd level of care. Conclusions: It is urgent to increase the ratio of clinical psychologists/100,000 inhabitants to reduce the risk posed for users by the deficient intensity with which psychological treatments are currently practiced. It is necessary to esta-blish standards for the workload of clinical psychologists in order to offer an adequate quality of care, and to integrate measurable indicators of quality in mental health information systems (AU)

Concordance of the ACR TI-RADS.

BACKGROUND: Ultrasonography (US) is the method of choice for evaluating thyroid nodules. In 2017, the American College of Radiology (ACR) created a classification system based on US characteristics. For the system to be adopted, it must be reproducible. OBJECTIVES: To determine the intraobserver and interobserver variability of the ACR TI-RADS. METHODS: Cross-sectional study; three radiologists with different levels of experience used the ACR TI-RADS to classify 100 nodules on two occasions one month apart, and we calculated the intraobserver and interobserver variability. RESULTS: Regarding intraobserver variability, the first radiologist had nearly perfect concordance for composition, echogenicity, shape, and margins and substantial concordance for echogenic foci; the second radiologist had nearly perfect concordance for composition, echogenicity, shape, and margins and substantial concordance for echogenic foci, and the third radiologist had nearly perfect concordance for composition, echogenicity, and shape and substantial concordance for margins and echogenic foci. The interobserver concordance was calculated for the two readings; the concordance was substantial except for shape in the first reading and for echogenicity and margins in the second reading, which had moderate concordance. CONCLUSIONS: The ACR TI-RADS classification system is reproducible.

Hypofractionated whole breast irradiation after IORT treatment: evaluation of acute toxicity and cosmesis

Introduction Hypofractionated whole breast irradiation (HWBI) is the current standard of treatment after breast conservative surgery (BCS). Intraoperative radiotherapy (IORT) must be associated to WBI in patients showing high-risk factors of local recurrence in the definitive pathology report. The aim of this trial was to evaluate, for the first time, the acute toxicity and cosmesis of HWBI after photon-IORT. Materials and methods Twenty-six luminal breast cancer patients treated by BCS and IORT(20 Gy) were included between February and December 2019, in this prospective trial, of adjuvant HWBI (40.5 Gy/2.67 Gy/15 fractions). Acute toxicity (CTCAEv5.0) and cosmesis (Harvard scale), were assessed 3 months after treatment. Results All patients completed their treatment without interruptions. All cases were evaluable 3 months after treatment showing no toxicity ≥ G3 and excellent/good cosmesis assessment in 88% of the patients. Conclusion HWBI seems to have similar acute toxicity and cosmesis results than conventionally fractionated WBI in combination to photon-IORT after BCS (AU)

Clinical and Functional Results of Broström-Gould Procedure With Suture Tape Augmentation: An Evaluation Using Three Scales.

The mechanical superiority of suture tape augmentation associated with the Broström-Gould procedure for treating lateral ankle instability has been reported. This study aimed to describe functional results using the visual analog scale (VAS), American Orthopedic Foot & Ankle Society (AOFAS) scale, and Short Form of Quality of Life Survey (SF-36) in patients with ankle lateral instability who underwent the modified Broström-Gould repair and suture tape augmentation and to determine the recurrence of injury and the impact on the perception of its stability. This retrospective cohort study included patients with lateral ankle instability treated using the modified Broström-Gould procedure and suture tape augmentation from December 2015 to July 2018 with a 6- to 36-month follow-up. Clinical and functional results were evaluated using the 3 aforementioned scales. p ≤ 0.05 was considered statistically significant. Twenty-eight patients were included, 18 (64%) males and 10 (36%) females (mean ± standard deviation age of 33.25 ± 12.73). The mean pre- and postoperative VAS scores were 6 ± 1.18 and 0.53 ± 0.92, respectively. The average pre- and postoperative AOFAS scores were 65.89 ± 15.08 and 94.60 ± 6.88, respectively; results were excellent (91 to 100) in 18 (64%) patients and good (81 to 90) in 10 (36%). Three patients experienced recurrence of injury treated with physical therapy, and their progress was satisfactory; stability perception was maintained. Excellent clinical and functional results were demonstrated in our study using suture tape augmentation in the modified Broström-Gould procedure, which probably protects against the recurrence of lateral ankle instability.

Diferencias en el metabolismo mineral óseo hiperparatiroidismo primario normocalcémico respecto al hiperparatiroidismo primario clásico / Differences in bone mineral metabolism normocalcemicprimary hyperparathyroidism with respect to classicalprimary hyperparathyroidism

OBJETIVO: El hiperparatiroidismo primario normocalcémico es una variedad menos conocida del hiperparatiroidismo primario clásico. Presentamos en este estudio sus manifestaciones clínicas y los datos relacionados con el metabolismo mineral óseo, tanto desde el punto de vista analítico como densitométrico, comparando los mismos con un grupo de pacientes afectos de hiperparatiroidismo primario clásico, con hipercalcemia. MATERIAL Y MÉTODOS: Estudio de casos y controles donde consideramos caso a pacientes afectos de hiperparatiroidismo primario normocalcémico (n=25) y control (n=25) a pacientes con hiperpartiroidismo primario con hipercalcemia (hiperparatiroidismo primario clásico). Se les efectuó una evaluación clínica completa con recogida de datos clínicos y realizándose determinaciones analíticas en sangre y orina de 24h, así como la estimación de la densidad mineral ósea y el trabecular bone score por densitometría (absorciometría radiológica dual, DXA) y los parámetros ultrasonográficos en el calcáneo. RESULTADOS: En el estudio clínico, los pacientes afectos de hiperparatiroidismo primario clásico solo muestran una mayor prevalencia de urolitiasis (OR: 9,333; IC 95%: 1,50-82,7) en comparación con los pacientes que sufren un hiperparatiroidismo primario normocalcémico. En todos los demás parámetros clínicos, analíticos, densitométricos y ultrasonográficos, no se aprecian diferencias estadísticamente significativas entre ambos grupos. CONCLUSIONES: Con la excepción de los niveles séricos de calcio y la prevalencia de urolitiasis, el hiperparatiroidismo normocalcémico cursa de manera indistinguible del hiperparatiroidismo clásico

OBJECTIVE: Normocalcemic primary hyperparathyroidism is a less known variety of classical primary hyperparathyroidism. In this paper, we present its clinical expression and data related to bone mineral metabolism, both analytically and densitometrically, comparing them with a group of patients with classic primary hyperparathyroidism, with hypercalcemia. MATERIAL AND METHODS: Study of cases and controls where we consider case of patients with normocalcemic primary hyperparathyroidism (n=25) and control (n=25) of patients with primary hyperpartyroidism with hypercalcemia (classical primary hyperparathyroidism). A complete clinical assessment was carried out with clinical data collection and24h blood and urine analytical determinations were performed, as well as estimating bone mineral density and trabecular bone score by densitometry (dual x‐ray absorptiometry, DXA) and ultrasound parameters in the calcaneus. RESULTS: In this clinical study, patients with classic primary hyperparathyroidism only show a higher prevalence of urolithiasis (OR: 9.333; 95% CI: 1.50‐82.7) compared to patients suffering from a normocalcemic primary hyperparathy‐roidism. In all other clinical, analytical, densitometric and ultrasonographic parameters, there are no statistically significant differences between the two groups. CONCLUSIONS: Apart from serum calcium levels and the prevalence of urolithiasis, normocalcemic hyperparathyroidism is indistinguishable from classical hyperparathyroidism

Use of micafungin as antifungal prophylaxis in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) in Spain (GETH-MIC).

OBJECTIVE: The fungal infections remain an important problem in the allogeneic stem cell trasnsplantation (allo-SCT) setting and thus, anti-fungal prophylaxis is commonly used. The antifungal drug should offer activity, at least against Candida and Aspergillus spp., a good safety profile and low probability interactions. Micafungin could theoretically fulfill these requisites. The aim of the study was to describe the experience with micafungin as primary prophylaxis in patients undergoing allo-SCT in a cohort of Spanish centres, and to evaluate its efficacy and tolerability in this population. METHODS: Retrospective multicentre observational study including all consecutive adult patients admitted for allo-SCT in participating centres of the Grupo Español de Trasplante Hematopoyético (GETH), from January 2010 to December 2013, who received micafungin as primary prophylaxis during the neutropenic period. RESULTS: A total of 240 patients from 13 centres were identified and 159 patients were included for the analysis. Most patients (95.6%) received 50 mg/day of micafungin. During the follow-up, 7 (4.4%) patients developed breakthrough invasive fungal disease, 1 proven and 6 probable; one patient discontinued the drug because of serious drug interactions. Prophylaxis with micafungin was considered effective in 151 (94.9%) patients. CONCLUSIONS: According to our experience, micafungin is an appropriate alternative for antifungal prophylaxis in patients undergoing an allo-HSCT, because its efficacy, its low profile of drug interactions and side-effects.
