Aplicación de tecnologías móviles (m-Salud) y salud electrónica (e-Salud) en el manejo y en la prevención de la litiasis renal: revisión sistemática / Mobile and eHealth technologies in the management and prevention of nephrolithiasis: A systematic review

Introducción La litiasis renal (LR) es una enfermedad urológica común, que a menudo requiere de cuidados a largo plazo. Las tecnologías de salud móvil (m-Salud) y salud electrónica (e-Salud) tienen el potencial de mejorar el manejo de las enfermedades crónicas e impactar sobre los patrones de la conducta. Para evaluar la aplicabilidad de estas herramientas en la mejora del tratamiento y la prevención de la LR, nos propusimos evaluar los datos actuales sobre el uso, los beneficios y las limitaciones de la m-Salud y la e-Salud en la LR. Métodos Se realizó una revisión sistemática de los estudios de investigación primaria sobre m-Salud y e-Salud en la evaluación y tratamiento de la LR. Dos investigadores independientes examinaron las citas por título y resumen para determinar su pertinencia y, a continuación, se realizó una revisión del texto completo para obtener un resumen descriptivo de los estudios. Resultados Se incluyeron 37 artículos para el análisis. Las principales áreas de interés fueron: 1) botellas de agua «inteligentes» y aplicaciones de dispositivos móviles para el seguimiento del consumo de líquidos, que mostraron un aumento de la ingesta en la mayoría de los estudios; 2) plataformas de seguimiento de stent ureterales, que mejoraron la tasa de stent retenidos a largo plazo; 3) clínicas virtuales para el tratamiento de la LR, las cuales han mejorado el acceso, han reducido costes y han mostrado resultados satisfactorios; 4) plataformas de endoscopia para teléfonos inteligentes, que ofrecieron una buena calidad de imagen respecto a sus costes en entornos de recursos limitados, y 5) información sobre la LR en línea para pacientes, la cual generalmente se caracterizó por ser de mala calidad y/o precisión, particularmente en YouTube®. La mayoría de los estudios eran pruebas de concepto o estudios de intervención de un solo brazo, con una evaluación limitada de la eficacia o de los resultados clínicos a largo plazo.

Introduction Kidney stone disease (KSD) is a common urological condition that often requires long-term care. Mobile health (mHealth) and eHealth technologies have the potential to enhance chronic disease management and behavioral change. To assess opportunities to apply these tools to improve KSD treatment and prevention, we aimed to assess current evidence on the use, benefits, and limitations of mHealth and eHealth in KSD. Methods We performed a systematic review of primary research studies of mHealth and eHealth in the evaluation and management of KSD. Two independent researchers screened citations by title and abstract for relevance, then full-text review was performed for descriptive summary of the studies. Results A total of 37 articles were included for analysis. Primary domains of evidence included: 1) “smart” water bottles and mobile-device apps for tracking fluid consumption, which showed increased intake in most studies; 2) ureteral stent tracking platforms, which improved the rate of long-term retained stents; 3) virtual stone clinics, which have been suggested to increase access, lower costs, and have satisfactory outcomes; 4) smartphone-based endoscopy platforms, which offered cost-effective image quality in resource-limited settings; 5) patient information about KSD online, which was typically characterized as poor quality and/or accuracy, particularly on YouTube. Most studies were proof-of-concept or single-arm intervention designs, with limited assessment of effectiveness or long-term clinical outcomes. Conclusions Mobile and eHealth technologies have significant real-world applications to KSD prevention, intervention, and patient education. A lack of rigorous effectiveness studies currently limits evidence-based conclusions and incorporation in clinical guidelines. (AU)

Aplicaciones clínicas, experimentales y resultados del uso de diferentes dispositivos de aspiración en la cirugía intrarrenal retrógrada. Revisión sistemática / Experimental and clinical applications and outcomes of using different forms of suction in retrograde intrarenal surgery. Results from a systematic review

Objetivo Identificar los últimos avances en los dispositivos de aspiración para la cirugía retrógrada intrarrenal (CRIR) y la ureteroscopia en el tratamiento de la litiasis, y evaluar los resultados de su aplicación. Procedimiento El 4 de enero de 2023 se realizó una búsqueda bibliográfica sistemática en Scopus, PubMed y EMBASE. Solo se incluyeron artículos en inglés; se aceptaron estudios en la población pediátrica y estudios en adultos. Se excluyeron los estudios duplicados, los informes de casos, las cartas al editor y los resúmenes de congresos. Hallazgos principales Se seleccionaron 21 trabajos. Se han propuesto varios sistemas de aspiración para la CRIR: a través de la vaina de acceso ureteral o directamente por el endoscopio. La inteligencia artificial también puede desempeñar un papel, monitorizando los valores de la presión y del flujo de irrigación. Todas las técnicas propuestas mostraron resultados perioperatorios satisfactorios en cuanto a tiempo quirúrgico, tasa libre de cálculos (TLC) y fragmentos residuales. Además, la reducción de la presión intrarrenal (mediante la aspiración) también se asoció a una tasa de infección menor. Incluso los estudios que incluyen cálculos renales con un diámetro de 20mm o superior informan de una mayor TLC y una reducción de las complicaciones postoperatorias. Sin embargo, la falta de parámetros bien establecidos para la presión de la aspiración y el flujo de líquido impide la estandarización del procedimiento. Conclusión Como ha sido demostrado en los estudios incluidos, el uso de dispositivos de aspiración en el tratamiento quirúrgico de los cálculos urinarios favorece la obtención de una TLC mayor y reduce las complicaciones infecciosas. La CRIR con sistema de aspiración podría sustituir a la técnica tradicional, gracias a sus ventajas asociadas al control de la presión intrarrenal y aspiración del polvo fino. (AU)

Objective To identify the latest advances in suction devices and evaluate their effect in Retrograde intrarenal surgery (RIRS) and ureteroscopy for stones. Basic procedures A systematic literature search was performed on 4th January 2023 using Scopus, PubMed, and EMBASE. Only English papers were included; both pediatric and adult studies were accepted. Duplicate studies, case reports, letters to the editor, and meeting abstracts were excluded. Main findings Twenty-one papers were selected. Several methods have been proposed for suction use in RIRS, such as through the ureteral access sheath or directly to the scope. Artificial intelligence can also regulate this system, monitoring pressure and perfusion flow values. All the proposed techniques showed satisfactory perioperative results for operative time, stone-free rate (SFR), and residual fragments. Moreover, the reduction of intrarenal pressure (induced by aspiration) was also associated with a lower infection rate. Even the studies that considered kidney stones with a diameter of 20mm or higher reported higher SFR and reduced postoperative complications. However, the lack of well-defined settings for suction pressure and fluid flow prevents the standardization of the procedure. Conclusion Aspiration device in the surgical treatment of urinary stones favours a higher SFR, reducing infectious complications, as supported by the included studies. RIRS with a suction system provided to be a natural successor to the traditional technique, regulating intrarenal pressure and aspirating fine dust. (AU)

Impact of initiation of SGLT2 inhibitor treatment on the development of arrhythmias in patients with implantable cardiac devices.

INTRODUCTION AND OBJECTIVES: Sodium-glucose cotransporter type 2 inhibitors (SGLT2i) have been associated with improved prognosis in patients with heart failure, but their impact on atrial arrhythmic (AA) and ventricular arrhythmic (VA) events is not fully understood. METHODS: This multicenter retrospective study included patients with implantable cardioverter-defibrillators who initiated treatment with SGLT2i. AA and VA events were compared in 2 time periods for each patient: 1 year before and 1 year after starting SGLT2i. RESULTS: The study included 195 patients (66.8 [61.3-73.1] years, 18.5% women). In the post-SGLT2i period, there was a reduction in the percentage of patients with any VA (pre: 52.3% vs post: 30.3%; P<.001) and clinically relevant VA (excluding nonsustained ventricular tachycardia) (pre: 21.5% vs post: 8.7%; P<.001). There was also a decrease in the number of episodes per patient/y of nonsustained ventricular tachycardia (pre: 2 (1-5) vs post: 1 (0-2); P<.001) and sustained ventricular tachycardia (pre: 1 (1-3) vs post: 0 (0-2); P=0.046). However, no differences were observed in the prevalence of AA (24.7% vs 18.8%; P=.117) or the burden of atrial fibrillation (pre: 0% (0-0.1) vs post: 0% (0-0); P=.097). CONCLUSIONS: Initiation of SGLT2i treatment was associated with a decrease in the percentage of patients with relevant VA but this effect was not observed for AA.

Uso de dispositivos móviles y alteraciones cervicales en estudiantes universitarios / Use of mobile devices and cervical disorders in university students / Uso de dispositivos móveis e distúrbios cervicais em estudantes universitários

Las alteraciones cervicales son un problema multifactorial que afecta a la sociedad moderna. Posturas viciosas, traumatismos y defectos congénitos relacionados con la columna cervical pueden desarrollar inestabilidad, pinzamiento radicular, cervicoartrosis y cervicalgias. Objetivo. Relacionar el uso de dispositivos móviles con las alteraciones cervicales en estudiantes universitarios. Materiales y métodos. Estudio descriptivo, observacional, que se realizó entre los meses de mayo y julio del 2023, cuya muestra fue de 172 estudiantes universitarios que se obtuvo aplicando la fórmula para el cálculo muestral de poblaciones conocidas, mediante un muestreo no probabilístico. Se utilizó el test goniométrico para medir el rango articular, el test postural para identificar las alteraciones posturales, la técnica de palpación para identificar dolor inespecífico, prueba de resistencia para los músculos flexores (NFMET) y extensores (NEET), por último, se realizó la prueba de Spurling para identificar casos de radiculopatías. Resultados. Aunque las relaciones estadísticas no fueron consistentes, se observó que quienes utilizaron más tiempo los teléfonos celulares (87,0%) mostraron más limitaciones cervicales que los usuarios menos frecuentes (73,5%). La movilidad articular fue limitada en el 84,3% de la población, especialmente en varones (93,5%); la resistencia muscular normal en extensión fue más prevalente en el caso de los hombres (84,9%), mientras que la resistencia alterada en flexión fue más prevalente en mujeres (94,9%). Conclusiones. Según los resultados obtenidos en esta investigación, no se encontró suficiente evidencia para determinar una relación estadísticamente significativa (P˃0,05) entre las alteraciones cervicales y el uso de teléfonos celulares, aunque se observó una mayor limitación en el caso de quienes más tiempo utilizaban el dispositivo móvil.

Cervical disorders are a multifactorial problem affecting modern society. Vicious postures, trauma and congenital defects related to the cervical spine can develop instability, radicular impingement, cervicoarthrosis and cervicalgia. Objective. To relate the use of mobile devices with cervical disorders in university students. Materials and methods. Descriptive, observational study carried out between May and July 2023, with a sample of 172 university students obtained by applying the formula for the sample calculation of known populations, by means of non-probabilistic sampling. The goniometric test was used to measure joint range, the postural test to identify postural alterations, the palpation technique to identify non-specific pain, resistance test for flexor (NFMET) and extensor (NEET) muscles, and finally, the Spurling test was performed to identify cases of radiculopathy. Results. Although the statistical relationships were not consistent, it was observed that those who used cell phones longer (87.0%) showed more cervical limitations than less frequent users (73.5%). Joint mobility was limited in 84.3% of the population, especially in men (93.5%); normal muscular endurance in extension was more prevalent in men (84.9%), while impaired endurance in flexion was more prevalent in women (94.9%). Conclusions. According to the results obtained in this investigation, there was not enough evidence to determine a statistically significant relationship (P˃0.05) between cervical alterations and cell phone use, although a greater limitation was observed in the case of those who used the mobile device the longest.

Retiro de dispositivo de oclusión septal transcateterismo en una paciente con comunicación interventricular / Removal of Transcatheter Septal Occlusion Device in a Patient with Ventricular Septal Defect

Introducción: Las complicaciones asociadas al procedimiento de colocación de un dispositivo de oclusión septal se presentan en menos del 10 por ciento de los casos. La embolización requiere de cirugía cardíaca, por lo que se incrementa el riesgo de la mortalidad. Objetivo: Presentar el caso en una paciente con comunicación interventricular e hipertensión pulmonar severa que se le retiró el dispositivo de oclusión septal transcateterismo. Presentación de caso: Se presentó una mujer de 24 años de edad con comunicación interventricular, insuficiencia cardíaca (New York Heart Association) clase IV e hipertensión pulmonar tipo 2, que se programó para la colocación de dispositivo de oclusión septal, sin embargo, presentó fallo en la colocación del dispositivo y defecto residual de 7 mm, por lo que se realizó el retiro de este 48 h después sin presentar complicaciones. Conclusiones: Aunque el cierre transcateterismo de la comunicación interventricular es una alternativa segura y efectiva a la cirugía, no está exento de complicaciones. En caso de translocación del dispositivo de oclusión septal este debe ser retirado durante el mismo procedimiento, ya que el riesgo de embolización es elevado y en caso de presentarse, el riesgo de muerte se incrementa(AU)

Introduction: Complications associated with the placement procedure of a septal occlusion device occur in less than 10percent of cases. Embolization requires cardiac surgery, which increases the risk of mortality. Objective: To report the case of a patient with ventricular septal defect and severe pulmonary hypertension who had the transcatheter septal occlusion device removed. Case report: We report the case report of a 24-year-old woman with ventricular septal defect, heart failure (New York Heart Association) class IV and type 2 pulmonary hypertension. She was scheduled for placement of a septal occlusion device, however, the placement of the device failed and had a residual defect of 7 mm, so the placement was removed 48 hours later without complications. Conclusions: Although transcatheter closure of the ventricular septal defect is a safe and effective alternative to surgery, it is not free of complications. In case of translocation of the septal occlusion device, it must be removed during the same procedure, since the risk of embolization is high and if it occurs, the risk of death increases(AU)

Tratamiento endovascular de aneurismas con anatomía aórtica compleja / Endovascular treatment of aneurysms with complex aortic anatomy

RESUMEN Introducción: la anatomía arterial es la principal limitante para el abordaje aórtico endovascular estándar. Presentamos nuestra experiencia para la reparación endovascular de aneurismas aórticos complejos. Material y métodos: estudio observacional retrospectivo en pacientes con aneurismas complejos (yuxta/pararrenales y toracoabdominales) tratados en forma consecutiva mediante: endoprótesis fenestradas (FEVAR), ramificadas (BEVAR), con EndoAnchors (ESAR), o en chimenea (ChEVAR). La decisión de la técnica fue determinada con base en la anatomía arterial. Resultados: se evaluaron los últimos 50 procedimientos (6 mujeres; edad promedio 71,3 años; diámetro 69,6mm; 3 pacientes con aneurismas complicados), de los cuales 22 recibieron FEVAR (2,8 fenestraciones / paciente), 11 BEVAR, 11 ESAR y 6 ChEVAR (1,8 chimeneas /paciente). La tasa de éxito técnico fue del 100% (ausencia de endoleak I o III con permeabilidad adecuada de los vasos viscerales). A 30 días 3 pacientes fallecieron (6%). Durante el seguimiento, 5 pacientes presentaron oclusión de la arteria renal, repermeabilizada en 4. Cuatro pacientes desarrollaron un endoleak tipo IA (3 ESAR secundarios y un ChEVAR), un paciente un endoleak IC y un cuarto uno IIIB (22%, 3 de los 11 ESAR, ninguno de los FEVAR industriales). En el análisis de supervivencia, la supervivencia global fue del 88,6% al año, y libre de reoperación del 86,5%. Conclusiones: se trata de la primera publicación en nuestro medio que muestra un enfoque global del paciente con un aneurisma de aorta complejo, de acuerdo con sus características anatómicas. Estas tecnologías ya desempeñan un papel primario en el tratamiento de estos pacientes.

ABSTRACT Background: Arterial anatomy is the main limiting factor for standard endovascular aortic (EVAR) approach. We present our experience for endovascular repair of complex aortic aneurysms. Material and Methods: This is a retrospective observational study in patients with complex aneurysms (juxta/pararenal and thoracoabdominal) treated consecutively with: fenestrated (FEVAR), branched (BEVAR), EndoAnchors (ESAR), or chimney (ChEVAR) stents. The decision of the technique was determined based on the arterial anatomy. Results: The last 50 procedures were evaluated (6 women; mean age 71.3 years; diameter 69.6 mm; and 3 patients with complicated aneurysms), among whom 22 received FEVAR (2.8 fenestrated stents/patient), 11 BEVAR, 11 ESAR and 6 ChEVAR (1.8 chimney stents/patient). Technical success rate was 100% (absence of type I or III endoleak with adequate patency of the visceral vessels). Three patients died within the first 30 days (6%). During follow-up, 5 patients presented with renal artery occlusion, treated successfully in 4 cases. Four patients developed type IA endoleak (3 secondary ESAR and one ChEVAR), one patient IC endoleak and almost a quarter of cases type IIIB endoleak (22%, 3 out of 11 patients receiving ESAR, none of the industrial FEVAR group). In survival analysis, overall survival analysis was 88.6% at one year, and 86.5% of cases were free from reoperation. Conclusions: This is the first publication in our setting that shows a global approach to the patient with complex aortic aneurysm, according to the anatomical characteristics. These technologies already play a primary role in the treatment of these patients.

Efecto del implante anticonceptivo sub-dérmico de Etonogestrel sobre el peso corporal en mujeres en edad reproductiva

Objetivo: Analizar el efecto sobre el peso corporal de la anticoncepción hormonal continua mediante implante sub-dérmico liberador de etonogestrel (ENG) en mujeres en edad reproductiva atendidas en la consulta de planificación familiar de un hospital venezolano. Métodos: Investigación comparativa, con diseño cuasi experimental, de casos y controles, a etiqueta abierta, y prospectivo; con una muestra intencionada de 60 mujeres separadas para recibir bien sea un implante subdérmico (Implanon NXT®; casos) o un dispositivo intrauterino (DIU) de cobre (T de cobre; controles). Se evaluaron el peso corporal e índice de masa corporal antes y posterior de doce meses del uso del contraceptivo; así como las características demográficas de las usuarias, efectos adversos y efectividad anticonceptiva de cada método. Resultados: Luego de un año con el implante de ENG no se encontraron variaciones significativas respecto a las mediciones iniciales del peso corporal (61,21±8,30 vs. 61,23±9,50, p>0,5) e IMC (25,23±3.89 vs. 25,26 ±4,30; p>0,05); contrariamente, a lo observado entre las usuarias del DIU donde tanto el peso corporal como el IMC tuvieron un aumento significativo (P<0,05). Asimismo, la mayoría de las usuarias se mantuvieron en el mismo rango de peso donde se encontraban al iniciar el método (p<0,001); mientras que la ganancia ponderal fue mayor entre las usuarias del DIU (1,530±2,04 vs. 3,700±3,02; p<0,05). Conclusiones: El implante de ENG no produce aumento del peso corporal luego de 12 meses de uso, con mínimos efectos adversos y alta efectividad contraceptiva.

Aim: To analyse the effect on body weight of continuous hormonal contraception by releasing subdermal implant etonogestrel (ENG) in women of reproductive age treated in the family planning consultation of a Venezuelan hospital. Methods: Comparative and applied research, with quasiexperimental, case-control, open label and prospective design, with an intentional sample of 60 women separated to receive the contraceptive implant (Implanon NXT®; cases) or a cooper intrauterine device (IUD) (Cooper T; controls) was carried out. Body weight and body mass index were evaluated before and after 12 months of contraceptive use; as well as demographic characteristics of users, side effects, and contraceptive effectiveness of each method. Results: After one year with the ENG implant, no significant variations were found with respect to initial measurements of body weight (61.21±8.30 vs. 61.23±9.50, p>0.5) and BMI (25.23±3.89 vs 25.26±4.30; p>0.05); on the contrary, to what was observed among IUD users where both body weight and BMI had a significant increase (P<0.05). Likewise, most users remained in the same weight range as when starting the method (p<0.001); while weight gain was greater among IUD users (1,530±2.04 vs. 3,700±3.02; p<0.05). Conclusions: The ENG implant does not produce an increase in body weight after 12 months of use, with minimal adverse effects and high contraceptive efficacy.

The relationship between the use of digital display devices and headphones and primary headaches in children.

BACKGROUND: Headache represents the most common neurologic symptom in children. In this study, we investigated the relationship between watching television, listening to music with headphones, smartphone, tablet, and computer use, and primary headaches in children. We aimed to determine whether primary headache in children is associated with excessive use of digital display devices and headphones and whether reducing the use of digital display devices and headphones affects primary headache. METHODS: The study included 69 children with primary headaches and 64 with no headaches as a control group. All subjects were evaluated for demographic and headache characteristics and the use of digital display devices and headphones. Our recommendation for patients and families was to decrease the use of digital display devices and headphones, and the headache burden was re-evaluated after one month. RESULTS: Headache frequency was more common in patients who watched television and used smartphones or tablets for more than 6 hours per day. Using a smartphone or tablet for more than 3 hours daily was more common in the study group than the control group. Headache frequency decreased in all patients one month after the digital imaging device and headphones were restricted. CONCLUSIONS: Watching television and using a smartphone or tablet strongly associates with primary headaches during childhood.

INTRODUCCIÓN: La cefalea representa el síntoma neurológico más común en los niños. En este estudio se investigó la relación entre ver televisión, escuchar música con auriculares, el uso del teléfono inteligente o tableta y computadora y el dolor de cabeza primario en niños.

CONCLUSIONES: Ver la televisión y el uso de un teléfono inteligente o tableta se asocian estrechamente con el dolor de cabeza primario en la infancia.

Dispositivos médicos en tiempos de pandemia: Eficacia de un sistema artesanal de alto flujo en el manejo de pacientes hospitalizados por COVID-19

Evaluar la eficacia del dispositivo artesanal de asistencia respiratoria no invasivo de administración de presión positiva continua en las vías respiratorias (CPAP) Wayrachi en comparación con la cánula de alto flujo comercial (CAF) para el tratamiento de pacientes con SARS-CoV-2. Estudio realizado en el Hospital Honorio Delgado Espinoza de Arequipa (Hospital COVID-MINSA Arequipa). Se evaluó a las historias clínicas de pacientes con SARS-CoV-2, de severidad moderada o grave que requerían asistencia respiratoria no invasiva, hospitalizados en el servicio de medicina interna durante la segunda ola de COVID en el Perú. Se realizó un análisis de supervivencia considerando los días a la muerte comparando al Wayrachi con la CAF. Se exploró el efecto de las variables sobre la muerte mediante una regresión de Cox. Resultados: Se evaluaron 114 pacientes tratados con Wayrachi (56,44 %) y 88 con CAF (43,5 %), observándose una frecuencia de muerte de 34,2 % y 34,1 % respectivamente. Al comparar la frecuencia de muerte, o su sobrevida, en ambos manejos no se observó una diferencia significativa (p=0,986 y p=0,928), esto se mantuvo en el modelo multivariado. El CPAP Wayrachi tuvo resultados similares a los presentados por el equipo CAF comercial lo que lo indica como una opción eficaz para el manejo de pacientes COVID que requieran soporte respiratorio no invasivo.

To evaluate the efficacy of the Wayrachi continuous positive airway pressure (CPAP) non-invasive respiratory support device compared to the commercial high-flow cannula (CAF) for the treatment of patients with SARS-CoV-2. Study carried out at the Honorio Delgado Espinoza Hospital in Arequipa (Hospital COVID-MINSA Arequipa). The medical records of patients with SARS-CoV-2, of moderate or severe severity, who required non-invasive respiratory assistance, hospitalized in the internal medicine service during the 2nd wave of COVID in Peru, were evaluated. A survival analysis was performed considering days to death comparing Wayrachi with CAF. The effect of variables on death was explored using Cox regression. Results: 114 patients treated with Wayrachi (56.44%) and 88 with CAF (43.5%) were evaluated, observing a frequency of death of 34.2% and 34.1%, respectively. When comparing the frequency of death, or its survival, in both managements, no significant difference was observed (p=0.986 and p=0.928), this was maintained in the multivariate model. The Wayrachi CPAP had similar results to those presented by the commercial CAF equipment, which indicates it as an effective option for the management of COVID patients who require non-invasive respiratory support.

Clinical utility of a personalized and long-term monitoring device for Parkinson's disease in a real clinical practice setting: An expert opinion survey on STAT-ON™.

BACKGROUND: STAT-ON™ is an objective tool that registers ON-OFF fluctuations making possible to know the state of the patient at every moment of the day in normal life. Our aim was to analyze the opinion of different Parkinson's disease experts about the STAT-ON™ tool after using the device in a real clinical practice setting (RCPS). METHODS: STAT-ON™ was provided by the Company Sense4Care to Spanish neurologists for using it in a RCPS. Each neurologist had the device for at least three months and could use it in PD patients at his/her own discretion. In February 2020, a survey with 30 questions was sent to all participants. RESULTS: Two thirds of neurologists (53.8% females; mean age 44.9±9 years old) worked in a Movement Disorders Unit, the average experience in PD was 16±6.9 years, and 40.7% of them had previously used other devices. A total of 119 evaluations were performed in 114 patients (range 2-9 by neurologist; mean 4.5±2.3). STAT-ON™ was considered "quite" to "very useful" by 74% of the neurologists with an overall opinion of 6.9±1.7 (0, worst; 10, best). STAT-ON™ was considered better than diaries by 70.3% of neurologists and a useful tool for the identification of patients with advanced PD by 81.5%. Proper identification of freezing of gait episodes and falls were frequent limitations reported. CONCLUSION: STAT-ON™ could be a useful device for using in PD patients in clinical practice.

O impacto do uso de métodos contraceptivos orais na função sexual de mulheres em idade reprodutiva / The impact of the use of oral contraceptive methods on the sexual function of women of reproductive age

Objetivo: Investigar o impacto dos contraceptivos orais hormonais na função sexual de mulheres. Métodos: Estudo transversal realizado por meio do questionário traduzido e validado "Índice da Função Sexual Feminina", capaz de estimar o risco de disfunção sexual feminina. Dados sociodemográficos, ginecológicos, medicamentosos e outros foram avaliados e correlacionados estatisticamente a esse escore, estimando possíveis causas da disfunção sexual, com destaque para o uso de anticoncepcional oral. O estudo foi baseado em uma amostragem por conveniência, incluindo mulheres > 18 anos em idade reprodutiva, de 04/01/2021 a 04/01/2022, obedecendo aos critérios de inclusão e exclusão. Resultados: Participaram deste estudo 105 mulheres com média e desvio-padrão de idade de 23,4 ± 3,8 anos, predominantemente heterossexuais (84,0%) e bissexuais (13,2%). A maioria delas (93,4%) utiliza métodos contraceptivos, sendo esses anticoncepcional oral (45,3%), DIU hormonal (19,8%) e camisinha (17,0%). A composição hormonal mais utilizada foi levonorgestrel (26,4%) e etinilestradiol (25,5%). Oitenta por cento das mulheres são sexualmente ativas, 69,3% delas têm parceria fixa, 42,5% tinham relações quase sempre e 33,0% referiam que as relações sexuais eram sempre satisfatórias. Houve boa adequação da amostra (0,865) e significância estatística (p < 0,0001). Utilizar ou não método contraceptivo apresentou diferença nos domínios desejo, satisfação e dor. Contudo, as questões do histórico sexual foram as que mais apresentaram relevância estatística em relação aos domínios. Conclusão: Apesar de outros estudos serem necessários para provar a hipótese de que os contraceptivos orais têm impacto negativo na função sexual feminina, é clara a importância de os profissionais de saúde já estarem cientes dessa possibilidade e saberem como abordá-la.

Objective: To investigate the impact of hormonal oral contraceptives on women's sexual function. Methods: Cross-sectional study carried out using the translated and validated questionnaire "Index of Female Sexual Function", capable of estimating the risk of female sexual dysfunction. Sociodemographic, gynecological, medication and other data were evaluated and statistically correlated to this score, estimating possible causes of sexual dysfunction, with emphasis on the use of oral contraceptives. The study was based on a convenience sample, including women > 18 years of reproductive age, from 01/04/2021 to 01/04/2022, following inclusion and exclusion criteria. Results: The study included 105 women with a mean and standard deviation of (23.4 ± 3.8) years old, predominantly heterosexual (84.0%) and bisexual (13.2%). Most of them (93.4%) use contraceptive methods, these being (45.3%) oral contraceptives, (19.8%) hormonal IUDs and (17.0%) condoms. The most used hormonal composition was levonorgestrel (26.4%) and ethinylestradiol (25.5%). Eighty percent of the women are sexually active, 69.3% of them have a steady partner, 42.5% almost always had sex and 33.0% said that sex was always satisfactory. There was good sample adequacy (0.865) and statistical significance (p < 0.0001). Using or not using a contraceptive method showed a difference in the desire, satisfaction and pain domains. However, sexual history questions were the ones that showed the most statistical relevance in relation to the domains. Conclusion: Although further studies are needed to prove the hypothesis that oral contraceptives have a negative impact on female sexual function, it is clear that health professionals are already aware of this possibility and know how to approach it.

Removal Rate of the Tomofix® System after High Tibial Osteotomy is Higher Than Reported / A taxa de remoção do sistema Tomofix® após a osteotomia tibial alta é superior à relatada

Abstract Objective Medial open wedge high tibial osteotomy (MOWHTO) significantly relieves pain in the medial joint line in medial compartment osteoarthritis of the knee. But some patients complain of pain over the pes anserinus even 1 year after the osteotomy, which may require implant removal for relief. This study aims to define the implant removal rate after MOWHTO due to pain over the pes anserinus. Methods One hundred and three knees of 72 patients who underwent MOWHTO for medial compartment osteoarthritis between 2010 and 2018 were enrolled in the study. Knee injury and osteoarthritis outcome score (KOOS), Oxford knee score (OKS), and visual analogue score (VAS) were assessed for pain in the medial knee joint line (VAS-MJ) preoperatively, 12 months postoperatively, and yearly thereafter; adding VAS for pain over the pes anserinus (VAS-PA). Patients with VAS-PA ≥ 40 and adequate bony consolidation after 12 months were recommended implant removal. Results Thirty-three (45.8%) of the patients were male and 39 (54.2%) were female. The mean age was 49.4 ± 8.0 and the mean body mass index was 27.0 ± 2.9. The Tomofix medial tibial plate-screw system (DePuy Synthes, Raynham, MA, USA) was used in all cases. Three (2.8%) cases with delayed union requiring revision were excluded. The KOOS, OKS, and VAS-MJ significantly improved 12 months after MOWHTO. The mean VAS-PA was 38.3 ± 23.9. Implant removal for pain relief was needed in 65 (63.1%) of the103 knees. The mean VAS-PA decreased to 4.5 ± 5.6 3 months after implant removal (p < 0.0001). Conclusion Over 60% of the patients may need implant removal to relieve pain over the pes anserinus after MOWHTO. Candidates for MOWHTO should be informed about this complication and its solution.

Resumo Objetivo A osteotomia tibial alta com cunha de abertura medial (MOWHTO, do inglês medial open wedge high tibial osteotomy) alivia de forma significativa a dor na linha articular medial em casos de osteoartrite do compartimento medial do joelho. Alguns pacientes, porém, se queixam de dor nos tendões dos músculos sartório, grácil e semitendinoso (pata de ganso) mesmo 1 ano após a osteotomia, o que pode exigir a remoção do implante. Este estudo define a taxa de remoção do implante após a MOWHTO devido à dor nos tendões dos músculos sartório, grácil e semitendinoso. Métodos Cento e três joelhos de 72 pacientes submetidos à MOWHTO para tratamento da osteoartrite do compartimento medial entre 2010 e 2018 foram incluídos no estudo. A pontuação de desfecho de lesão no joelho e osteoartrite (KOOS, do inglês Knee Injury and Osteoarthritis Outcome Score), a pontuação dejoelho de Oxford (OKS, do inglês Oxford Knee Score) e a escala visual analógica (EVA) de dor na linha articular medial do joelho (EVA-MJ) foram avaliados antes da cirurgia. A EVA nos tendões dos músculos sartório, grácil e semitendinoso (EVA-PA) foi adicionada a essas avaliações, também realizadas 12 meses após o procedimento e, a seguir, anualmente. A remoção do implante foi recomendada em pacientes com EVA-PA ≥ 40 e consolidação óssea adequada em 12 meses. Resultados Trinta e três (45,8%) pacientes eram homens e 39 (54,2%), mulheres. A média de idade foi de 49,4 ±8,0, e o índice de massa corpórea (IMC) médio foi de 27,0 ± 2,9. O sistema placa-parafuso tibial medial Tomofix (DePuy Synthes, Raynham, MA, EUA) foi utilizado em todos os casos. Três (2,8%) casos foram excluídos devido ao retardo de consolidação e à necessidade de revisão. Os resultados nas escalas KOOS, OKS e EVA-MJ melhoraram significativamente 12 meses após a MOWHTO. A EVA-PA média foi de 38,3 ± 23,9. A remoção do implante para alívio da dor foi necessária em 65 (63,1%) dos 103 joelhos. Três meses após a remoção do implante, a EVA-PA média diminuiu para 4,5 ± 5,6 (p < 0,0001). Conclusão A remoção do implante pode ser necessária em mais de 60% dos pacientes para alívio da dor nos tendões dos músculos sartório, grácil e semitendinoso após a MOWHTO. Os candidatos à MOWHTO devem ser informados sobre esta complicação e sua resolução.
