INTRODUCTION: seizures can trigger fractures and dislocations. Injuries depend on the severity, duration and type of seizure. We present a case report of a male patient who presented with a bilateral central dislocation fracture of the hip following an episode of seizure. A case rarely described in the literature with complex and unusual management. CASE REPORT: a 77-year-old man with a history of moderate cognitive impairment suffered a bilateral central dislocation of the hip in the context of a generalized epileptic seizure. Clinically on arrival at the emergency department, the patient presented shortening of the right lower extremity compared to the contralateral, external rotation and joint locking on log roll test in both extremities. An imaging study and clinical optimization were performed prior to surgery. It was performed in two stages. First the left hip on the 8th day of admission, and the right hip on the 15th. In both surgeries the same procedure was performed, with implantation of an antiprotrusive ring and a double mobility cup prosthesis with an uncemented femoral stem. In the immediate postoperative period, the patient did not present any complications associated with the surgery. At 24-month follow-up, the patient performed full weight bearing with a Harris hip score (HHS) of 77 on the right hip and 79 on the left; 12 points on the WOMAC scale. No postoperative complications have occurred so far. CONCLUSIONS: these injuries are uncommon in our daily practice, where multiple options are available to address them. In our patient, the use of arthroplasty and antiprotrusive rings offers advantages over fracture synthesis techniques, such as early mobilization with moderate functional results and few postoperative complications.

INTRODUCCIÓN: las crisis convulsivas pueden desencadenar fracturas y luxaciones. Las lesiones dependen de la severidad, duración y el tipo de crisis. Presentamos un caso clínico de un varón que presentó una fractura luxación central bilateral de cadera tras episodio de crisis convulsiva. Un caso pocas veces descrito en la literatura con un manejo complejo y poco habitual. CASO CLÍNICO: paciente de 77 años con antecedentes de deterioro cognitivo moderado que sufrió una luxación bilateral central de cadera en contexto de una crisis convulsiva generalizada. Clínicamente, a su llegada a urgencias, el paciente presentaba un acortamiento de la extremidad inferior derecha en comparación con la contralateral, rotación externa y bloqueo articular a la realización del log roll test en ambas extremidades. Se realizó estudio de imagen y optimización clínica previo a cirugía. Se realizó en dos tiempos: primero la cadera izquierda al octavo día de ingreso y la cadera derecha al decimoquinto. En ambas cirugías se realizó el mismo procedimiento mediante implantación de anillo antiprotrusivo y prótesis con cotilo de doble movilidad con vástago femoral no cementado. En el postoperatorio inmediato, el paciente no presentó ninguna complicación asociada a la cirugía. En el seguimiento a los 12 meses, el paciente realiza carga completa con un Harris hip score (HHS) de 77 cadera derecha y 79 en la izquierda; 12 puntos en la escala WOMAC. No ha presentado complicaciones postoperatorias hasta el momento. CONCLUSIONES: estas lesiones son poco comunes en nuestra práctica diaria, donde disponemos de múltiples opciones para abordarlas. En nuestro paciente, el empleo de la artroplastía y de anillos antiprotrusivos nos ofrecen ventajas respecto a las técnicas de síntesis de la fractura, como una movilización precoz y evitar desarrollo prematuro de una artrosis postraumática, con resultados buenos, funcionales y pocas complicaciones postoperatorias.

Whole Health coaching to rural Veterans through telehealth: Advantages, gaps, and opportunities.

Background: The Veterans Health Administration (VHA) is one of the largest providers of telehealth in the United States and continues to lead the way in transforming healthcare services. VHA has been implementing its Whole Health (WH) initiative since 2018, a proactive practice empowering patients to take charge of their health and well-being. A key facilitator of the WH initiative is the WH coach who partners with Veterans to achieve their health-related goals. A gap exists in the literature regarding the understanding of WH coaches' use of telehealth to engage rural-residing Veterans. COVID-19 unexpectedly interrupted in-person VHA delivery of care, including WH coaching which primarily relied on in-person delivery and focused less on telehealth. During the pandemic, WH coaches had to adapt and integrate different modalities to engage their Veteran patients. We examined WH coaches' approaches to extending coaching to rural Veterans via technology, emphasizing the advantages of telehealth, existing gaps in telehealth delivery, and opportunities for telehealth as a coaching modality. Methods: This project was implemented as part of a larger mixed methods evaluation regarding WH coaching for rural Veterans; this manuscript presents the findings from the qualitative data from the larger study. The qualitative dataset is comprised of data collected using three different qualitative methods: four focus groups (n = 11; 3-4 participants per group), in-depth individual interviews (n = 9), and open-ended responses from a national web-based survey (n = 140). Focus group, in-depth interview, and open-ended survey data were collected sequentially and separately analyzed following each wave of data collection. Findings from the three analyses were then collaboratively merged, compared, reorganized, and refined by the evaluation team to create final themes. Results: Three final themes that emerged from the merged data were: (1) Advantages of Telehealth; (2) Telehealth Gaps for Rural Veterans, and (3) Strategies for Bridging Telehealth Gaps. Themes explicate telehealth advantages, gaps, and opportunities for rural Veteran WH coaching. Conclusion: Findings highlight that video telehealth alone is not sufficient for meeting the needs of rural Veterans. Digital technologies hold promise for equalizing health access gaps; however, both human factors and broadband infrastructure constraints continue to require WH coaches to use a mix of modalities in working with rural Veterans. To overcome challenges and bridge gaps, WH coaches should be ready to adopt a blended approach that integrates virtual, in-person, and lower-tech options.

Meeting the Needs of Rural Veterans: A Qualitative Evaluation of Whole Health Coaches' Expanded Services and Support during COVID-19.

The purpose of this qualitative study was to explore perspectives of Whole Health (WH) coaches at the Veterans Health Administration (VHA) on meeting the needs of rural Veterans during the COVID-19 pandemic. The evaluation design employed a qualitative description approach, employing focus groups and in-depth interviews with a convenience sample of WH coaches across the VHA system. Fourteen coaches who work with rural Veterans participated in either one of three focus groups, individual interviews, or both. The focus group data and in-depth interviews were analyzed separately using thematic analysis, and findings were then merged to compare themes across both datasets. Four primary themes were identified: bridging social risk factors for rural Veterans, leveraging technology to stay connected with Veterans at-a-distance, redirecting Veterans to alternate modes of self-care, and maintaining flexibility in coaching role during COVID-19. One overarching theme was also identified following a post-hoc analysis driven by interdisciplinary team discussion: increased concerns for Veteran mental health during COVID-19. Coaches reported using a variety of strategies to respond to the wide-ranging needs of rural Veterans during the pandemic. Implications of findings for future research and practice are discussed.

Estudio comparativo de efectividad entre la Hipnosis y la intervención Cognitivo-Conductual para la Deshabituación Tabáquica / Comparative study of effectiveness between Hypnosis and Cognitive-Behavioral intervention for Smoking Cessation

Introducción: El consumo de tabaco es la primera causa de muerte evitable. A muchos fumadores les gustaría dejar el hábito. Aun así, a pesar de la eficacia demostrada de las intervenciones, muchos no están dispuestos a realizar un intento debido a las altas tasas de recaída y al miedo a los efectos secundarios de los tratamientos empleados, inclinándose a probar métodos alternativos.Objetivo: Conocer si la intervención avanzada individual (multicomponente cognitiva-conductual) es más efectiva que la intervención con hipnoterapia en pacientes fumadores, como tratamiento para dejar de fumar.Metodología: Estudio cuasiexperimental. Se incluyeron pacientes fumadores con antecedentes de patología respiratoria. Fueron asignados, según su preferencia, a un grupo de intervención avanzada individual en tabaquismo (grupo A) - al que se realizó una terapia multicomponente para dejar de fumar- o a un grupo de hipnoterapia (grupo B) en el que se realizó hipnosis para dejar de fumar.Todos los pacientes recibieron el tratamiento farmacológico y las pautas de actuación habituales que se utilizan en las consultas externas para tratar la enfermedad.Resultados: Se encontraron diferencias significativas en la cesación del consumo de tabaco a los 6 meses, encontrándose valores inferiores tanto en el abandono como en la disminución del consumo en los pacientes a los que se les realizó hipnoterapia versus terapia multicomponente (p 0,023 y p 0,031 respectivamente). Conclusiones: La intervención para el abandono del tabaco que incorpora la hipnosis no ha demostrado ser tan eficaz como la terapia multicomponente en la población estudiada. (AU)

Introduction: Tobacco use is the number one preventable cause of death. Many smokers would like to kick the habit. Still, despite the proven efficacy of the interventions, many are reluctant to try due to high relapse rates and fear of side effects of the treatments used, and are inclined to try alternative approaches.Objetive: To know if the individual advanced intervention (cognitive-behavioural multicomponent) is more effective than the intervention with hypnotherapy in smokers, as a treatment to quit smoking.Methodology: Quasi-experimental study. Smokers with a history of respiratory pathology were included. They were assigned, according to their preference, to an advanced individual smoking cessation intervention group (group A) - which underwent multicomponent therapy to quit smoking - or to a hypnotherapy group (group B) in which hypnosis was performed to quit smoking. of smoking.All patients received the pharmacological treatment and the usual action guidelines that are used in outpatient clinics to treat the disease.Results: Significant differences were found in the cessation of tobacco consumption at 6 months, with lower values both in quitting and in the reduction of consumption in patients who underwent hypnotherapy versus multicomponent therapy (p 0.023 and p 0.031, respectively).Conclusions: Smoking cessation intervention incorporating hypnosis has not been shown to be as effective as multicomponent therapy in the population studied.

Disposable FFP2 and Type IIR Medical-Grade Face Masks: An Exhaustive Analysis into the Leaching of Micro- and Nanoparticles and Chemical Pollutants Linked to the COVID-19 Pandemic.

The COVID-19 pandemic has increased the worldwide production and use of disposable plastic face masks (DPFMs). The release of micro- and nanopollutants into the environment is one of the impacts derived from regulated and unregulated disposal of DPFMs. This study focuses on the emission of pollutants from medical-grade DPFMs when submerged in deionized water, simulating regulated and unregulated disposal of these masks. Three brands of FFP2 and three brands of Type IIR medical masks, produced in various countries (UK, EU, and non-EU), were investigated. Field emission gun scanning electron microscopy (FEG-SEM) was used to obtain high-resolution images of the micro- and nanoparticles, and 0.02 µm pore size inorganic membranes were used to retain and subsequently analyze smaller particle size nanoparticles (>20 nm) released from the DPFMs. Particles and fibers in the micro- and nanoscale were found in all six DPFM brands. SEM with energy-dispersive spectroscopy analysis revealed the presence of particles containing different heavy metals like lead, mercury, and arsenic. Inductively coupled plasma mass spectrometry analysis confirmed the leaching of trace heavy metals to water (antimony up to 2.41 µg/L and copper up to 4.68 µg/L). Liquid chromatography-mass spectrometry analysis identified polar organic species related to plastic additives and contaminants such as polyamide-66 monomers and oligomers.

Biopsia selectiva de ganglio centinela en pacientes con cáncer de endometrio. Inicio de la técnica en el Hospital Universitario Virgen Macarena / Sentinel lymph node biopsy in patients with endometrial cancer. Beginning of using the technique in the Virgen Macarena University Hospital

Antecedentes: La biopsia selectiva de ganglio centinela (BSGC) en el cáncer de endometrio se encuentra aún en periodo de estudio para validar su implantación protocolizada y evitar así la linfadenectomía pélvica y aortocava. Objetivo: Mostrar nuestros resultados durante el proceso de validación de la técnica y así colaborar para su implantación en otros centros. Método: Estudio observacional descriptivo prospectivo de pacientes intervenidas de cáncer endometrial en las que se realizó BSGC vía laparoscópica desde julio de 2016 a diciembre de 2019. Resultados: Los ganglios centinela (GC) en todas las pacientes fueron negativos para metástasis. Hubo una concordancia del 100% entre los resultados anatomopatológicos de los GC y de las posteriores linfadenectomías de validación. En ningún caso se objetivaron complicaciones operatorias durante la realización de la BSGC. Conclusión: La BSGC en pacientes en estadios iniciales de carcinoma endometrial es una técnica en fase de validación pero cuyos resultados son prometedores, pudiéndose llevar a cabo una cirugía menos invasiva de forma segura, evitando la comorbilidad asociada a la linfadenectomía.(AU)

Background: Sentinel lymph node biopsy (SLNB) in endometrial cancer is still being assessed in order to validate its standardised protocol to avoid pelvic and aortocaval lymphadenectomy. Objective: To present the results of the technique during the validation process, and work towards its implementation in other centres. Method: A prospective descriptive observational study of endometrial cancer patients who underwent laparoscopic SLNB from July 2016 to December 2019. Results: Sentinel lymph nodes (SLN) in all patients were negative for metastasis. There was a 100% agreement between the histopathology results of the SLN and the subsequent validation of lymphadenectomies. No surgical complications were observed in any of the cases during the performing of the SLNB. Conclusion: SLNB in patients in early stages of endometrial carcinoma is a technique in the validation phase, but the results of which are promising. This means that less invasive surgery can be carried out safely, avoiding comorbidity associated with lymphadenectomy.(AU)

Tumor de Brenner benigno asociado a tumor mucinoso borderline de ovario en paciente postmenopáusica / Benign Brenner tumour associated with a borderline mucinous tumour of the ovary in a post-menopausal patient

El tumor de Brenner es una neoplasia ovárica infrecuente de origen incierto, generalmente asintomática. Su diagnóstico es complejo, sin presentar patrones ecográficos específicos. Se ha asociado a tumores mucinosos con distinto potencial de malignidad, pudiendo encontrar componentes malignos o borderline que determinarán el tratamiento. Para su diagnóstico diferencial es esencial la realización de un estudio inmunohistoquímico, para objetivar el origen clonal del tumor de Brenner y de la estirpe mucinosa. Presentamos el caso de una mujer diagnosticada intraoperatoriamente de un tumor de Brenner asociado a un tumor mucinoso borderline de ovario, en el estudio definitivo posterior.(AU)

Brenner tumour is an uncommon neoplasm of the ovary of uncertain origin and often asymptomatic. Diagnostic is complex, without specific ultrasound patterns. It has been associated with mucinous tumours with different potential for malignancy, and it is possible to find malignant or borderline components that determine the treatment. For its differential diagnosis immunohistochemical study is essential, which shows, according to various studies, a clonal origin of Brenner and mucinous tumour. This is a case report of a Brenner tumour associated with a mucinous tumour, which in a definitive study showed to be associated with a borderline ovarian tumour component.(AU)

An investigation into the leaching of micro and nano particles and chemical pollutants from disposable face masks - linked to the COVID-19 pandemic.

The production of disposable plastic face masks (DPFs) in China alone has reached to approximately 200 million a day, in a global effort to tackle the spread of the new SARS-CoV-2 virus. However, improper and unregulated disposals of these DPFs has been and will continue to intensify the plastic pollution problem we are already facing. This study focuses on the emission of pollutants from 7 DPF brands that were submerged in water to simulate environmental conditions if these DPFs were littered. The DPF leachates were filtered by inorganic membranes, and both particle-deposited organic membranes and the filtrates were characterized using techniques such as FTIR, SEM-EDX, Light Microscopy, ICP-MS and LC-MS. Micro and nano scale polymeric fibres, particles, siliceous fragments and leachable inorganic and organic chemicals were observed from all of the tested DPFs. Traces of concerning heavy metals (i.e. lead up to 6.79 µg/L) were detected in association with silicon containing fragments. ICP-MS also confirmed the presence of other leachable metals like cadmium (up to 1.92 µg/L), antimony (up to 393 µg/L) and copper (up to 4.17 µg/L). LC-MS analysis identified polar leachable organic species related to plastic additives and contaminants; polyamide-66 monomer and oligomers (nylon-66 synthesis), surfactant molecules, dye-like molecules and polyethylene glycol were all tentatively identified in the leachate. The toxicity of some of the chemicals found and the postulated risks of the rest of the present particles and molecules, raises the question of whether DPFs are safe to be used on a daily basis and what consequences are to be expected after their disposal into the environment.

Outcome of treatment of MDR-TB or drug-resistant patients treated with bedaquiline and delamanid: Results from a large global cohort.

The World Health Organization (WHO) recommends countries introduce new anti-TB drugs in the treatment of multidrug-resistant tuberculosis. The aim of the study is to prospectively evaluate the effectiveness of bedaquiline (and/or delamanid)- containing regimens in a large cohort of consecutive TB patients treated globally. This observational, prospective study is based on data collected and provided by Global Tuberculosis Network (GTN) centres and analysed twice a year. All consecutive patients (including children/adolescents) treated with bedaquiline and/or delamanid were enrolled, and managed according to WHO and national guidelines. Overall, 52 centres from 29 countries/regions in all continents reported 883 patients as of January 31st 2021, 24/29 countries/regions providing data on 100% of their consecutive patients (10-80% in the remaining 5 countries). The drug-resistance pattern of the patients was severe (>30% with extensively drug-resistant -TB; median number of resistant drugs 5 (3-7) in the overall cohort and 6 (4-8) among patients with a final outcome). For the patients with a final outcome (477/883, 54.0%) the median (IQR) number of months of anti-TB treatment was 18 (13-23) (in days 553 (385-678)). The proportion of patients achieving sputum smear and culture conversion ranged from 93.4% and 92.8% respectively (whole cohort) to 89.3% and 88.8% respectively (patients with a final outcome), a median (IQR) time to sputum smear and culture conversion of 58 (30-90) days for the whole cohort and 60 (30-100) for patients with a final outcome and, respectively, of 55 (30-90) and 60 (30-90) days for culture conversion. Of 383 patients treated with bedaquiline but not delamanid, 284 (74.2%) achieved treatment success, while 25 (6.5%) died, 11 (2.9%) failed and 63 (16.5%) were lost to follow-up.

Eyelash loss in frontal fibrosing alopecia: Microscopic features of two cases.

BACKGROUND: To report two cases of eyelash loss in Frontal Fibrosing Alopecia, providing microscopic description of the eyelashes and possible association with Demodex folliculorum. CASE PRESENTATION: We present two cases of postmenopausal women diagnosed with frontal fibrosing alopecia who consulted the ophthalmology department for eyelid itching and eyelash loss. On examination, there were no signs of blepharitis, but loss of lashes was observed, and the remaining eyelashes detached easily from the eyelid. The eyelashes were examined microscopically. The bulbs were small and narrow, and the caliber of the lashes was irregular, with thinner and thicker areas. The pigment distribution was irregular; there were portions with greater or lesser accumulation. In the second case, clusters of Demodex folliculorum were observed near the eyelash root. CONCLUSION: This is the first microscopic description of eyelash loss in frontal fibrosing alopecia in the published literature. We describe small, narrow bulbs, irregular caliber of the eyelashes and irregular pigment distribution. In the second case, in which we found Demodex folliculorum infestation, there was eyelash loss even though the disease was not very advanced. We suggest that there might be an association whereby Demodex infestation might accelerate autoimmune inflammation, leading to premature eyelash loss.

Entropy and canonical ensemble of hybrid quantum classical systems.

In this work we generalize and combine Gibbs and von Neumann approaches to build, for the first time, a rigorous definition of entropy for hybrid quantum-classical systems. The resulting function coincides with the two cases above when the suitable limits are considered. Then, we apply the MaxEnt principle for this hybrid entropy function and obtain the natural candidate for the hybrid canonical ensemble (HCE). We prove that the suitable classical and quantum limits of the HCE coincide with the usual classical and quantum canonical ensembles since the whole scheme admits both limits, thus showing that the MaxEnt principle is applicable and consistent for hybrid systems.

Detection of trace sub-micron (nano) plastics in water samples using pyrolysis-gas chromatography time of flight mass spectrometry (PY-GCToF).

The identification and quantification of micro and nanoplastics (MPs and NPs respectively) requires the development of standardised analytical methods. Thermal analysis methods are generally not considered a method of choice for MPs analysis, especially in aqueous samples due to limited sample size introduction to the instrument, decreasing the detection levels. In this article, pyrolysis - Gas chromatography time of flight mass spectrometry (Py-GCToF) is used as a method of choice for detection of MPs and NPs due to its unprecedented detection capabilities, in combination with PTFE membranes as sample support, allow for smaller particle sizes (>0.1 µm) in water samples to be identified. The utilisation of these widely used membranes and the identification of several and specific (marker) ions for the three plastics in study (polypropylene (PP), polystyrene (PS) and polyvinyl chloride (PVC)), allows for the extraction of individual plastics from complex signals at trace levels. The method was validated against a number of standards, containing known quantities of MPs. Detection levels were then determined for PVC and PS and were found to be below <50 µg/L, with repeatable data showing good precision (%RSD <20%). Further verification of this new method was achieved by the analysis of a complex sample, sourced from a river. The results were positive for the presence of PS with a semi-quantifiable result of 241.8 µg/L. Therefore PY-GCToF seems to be a fit for purpose method for the identification of MPs and NPs from complex mixtures and matrices which have been deposited on PTFE membranes.

Screening for Resistance to Meloidogyne enterolobii in Capsicum annuum Landraces From Mexico.

Meloidogyne enterolobii has become an economically important plant parasitic nematode worldwide because of its high aggressiveness, increasing geographic distribution, wide host range, and pathogenicity in pepper (Capsicum annuum) cultivars carrying resistance genes to Meloidogyne incognita, Meloidogyne arenaria, and Meloidogyne javanica. The objectives of this study were to identify landraces of peppers resistant to M. enterolobii and analyze the relationship between resistance indicators and the phenotype parameters of plant height, stem width, leaf length, leaf width, relative chlorophyll, and number of flowers. Ninety landraces of C. annuum were collected from several states of Mexico and were inoculated with 2,000 eggs of M. enterolobii. Eleven resistant landraces were selected and confirmed with a second inoculation experiment. Seventy-five days after inoculation, in both experiments, the resistance of landraces UTC66, UTC90, UTC67, UTC88, and UTC81 to M. enterolobii was consistent. Although genotypes UTC24, UTC79, UTC65, UTC68, UTC69, and UTC25 were susceptible, these landraces had a significantly higher proportion of resistant plants, less root galling, and a lower reproductive index, in comparison with the rest of the 79 genotypes and the susceptible control, which were highly susceptible in both experiments. There was no correlation between resistant indicators and phenotypic parameters, although plant height, relative chlorophyll, and number of flowers were in general significantly affected compared with noninoculated controls, indicating that the nematodes reduce the growth and yield of peppers. Results indicate that all resistant plants from these landraces are promising sources of resistance for the development of pepper cultivars resistant to M. enterolobii.
