RESUMO

The present work experimentally examines whether a Spanish-speaking healthcare provider (an identity safety cue) increases the anticipated quality of care and healthcare utilization intentions of Latinx Americans (N = 180) and whether this effect is moderated by ethnic centrality. We find that providing Spanish-language services, versus not, on a healthcare facility's webpage significantly increases both anticipated quality of care and healthcare utilization intentions-but only for Latinx Americans who perceive their ethnicity as highly central to their self-concept. Likewise, we find that anticipated quality of care mediates the effect that identity safety cues have on healthcare utilization intentions only for Latinx Americans high on ethnic centrality. These findings demonstrate that members of minoritized ethnic groups shown to be the most susceptible to experiencing concerns of discrimination (people high on ethnic centrality) are also the most likely to benefit from identity safety cues that are designed to mitigate these very concerns.

RESUMO

Introducción: El proceso diagnóstico de los sarcomas de partes blandas del aparato locomotor (SPBAL) sigue siendo comprometido, con casos de resecciones no planificadas (cirugías «whoops»). Este estudio evalúa la frecuencia de este tipo de procedimientos, tratando de identificar características de los pacientes, tumores, tratamiento quirúrgico y resultados. Material y métodos: Se revisan de forma retrospectiva 131 pacientes tratados de forma quirúrgica en nuestro centro entre octubre de 2018 y diciembre de 2021 de un SPBAL. Se excluyen los pacientes con SPBAL localizados en vísceras, mediastino, corazón, retroperitoneo, peritoneo y aparato genital. Las diferencias entre pacientes con resecciones planificadas y no planificadas fueron evaluadas con pruebas χ2 y un modelo de regresión multivariado de Cox. Resultados: Las resecciones no planificadas de SPBAL han tenido lugar en 18% de los pacientes de nuestra área, principalmente en tumores menos de 5 cm y localizados superficiales a la fascia; 29,2% de estos pacientes no disponían de una prueba de imagen previa. No se ha demostrado que una cirugía «whoops» pueda suponer una disminución de la supervivencia o una mayor tasa de recidivas. Conclusiones: Recomendamos la realización de una prueba de imagen siempre previa a la extirpación de cualquier tipo de tumoración de tejidos blandos, así como la adherencia a las guías de remisión a centros de referencia.(AU)


Introduction: The diagnosis process of soft tissue sarcomas of the musculoskeletal system (SPBAL) continues to be complex, with cases of unplanned excisions (“whoops” surgeries). This study evaluates the frequency of these type of procedures, trying to indentify patient characteristics, tumors, surgical treatment and final results. Material and methods: 131 patients treated surgically between October 2018 and December 2021 of a SPBAL were retrospectively reviewed. Patients with SPBAL located in the viscera, mediastinum, heart, retroperitoneum, peritoneum and genital tract were excluded. Differences between patients with planned and unplanned excisions were assessed with chi2 tests and a Cox multivariate regression model. Results: Unplanned excisions of SPBAL have taken place in 18% of the patients in our área, mainly in tumors of less than 5 cm and located superficial to the fascia. 29,2% of these patients did not have a previous imaging test. It has not been shown that a “whoops” surgery can lead to a decrease in survival or a higher rate of recurrences. Conclusions: We recommend carrying out an imaging test always prior to the removal of any type of soft tissue tumor, as well as adherence to the referral guidelines to reference centers.(AU)

RESUMO

Introduction This study analyzed the impact of patients’ age, sex, vaccination, immunosuppressive treatment, and previous comorbidities on the risk of developing persistent COVID-19 or SARS-CoV-2 virus reinfection. Method Population-based observational retrospective study of a cohort of 110,726 patients aged 12 years or older, who were diagnosed with COVID-19 between June 1st, 2021 and February 28th, 2022 in the island of Gran Canaria. Results 340 patients suffered reinfection. The combination of advanced age, female sex and lack of complete or incomplete vaccination against COVID-19 was strongly predictive of reinfection (p<0.05). In the 188 patients who developed persistent COVID-19, the persistence of symptoms was more frequent in adult patients, women, and patients with a diagnosis of asthma. Complete vaccination was associated with a lower risk of reinfection ([OR] 0.05, 95%CI 0.04–0.07; p<0.05) and of developing persistent COVID-19 ([OR] 0.07, 95%CI 0.05–0.10; p<0.05). None of the patients with reinfection or persistent COVID-19 died during the period of the study Conclusions This study confirmed the link between age, sex, asthma and risk of persistent COVID-19. It was not possible to define the patient's comorbidities as a factor that influences the development of reinfection, but its association with age, sex, type of vaccine and hypertension was demonstrated. Higher vaccination coverage was associated with a lower risk of persistent COVID-19 or SARS-CoV-2 reinfection (AU)


Introducción Se analizó el impacto de la edad, el sexo, la vacunación, el tratamiento inmunosupresor y las comorbilidades previas del paciente sobre la condición de riesgo de desarrollar COVID-19 persistente o reinfección por el virus del SARS-CoV-2. Método Estudio retrospectivo observacional de base poblacional en una cohorte de 110.726 pacientes de 12 o más años de edad diagnosticados de COVID-19 entre el 1 de junio de 2021 y el 28 de febrero de 2022 en la isla de Gran Canaria. Resultados Trescientos cuarenta pacientes sufrieron reinfección por COVID-19. La combinación de edad avanzada, sexo femenino y falta de vacunación completa o incompleta contra la COVID-19 fue fuertemente predictiva de reinfección (p<0,05). En los 188 pacientes que desarrollaron COVID-19 persistente, la persistencia de síntomas fue más frecuente en pacientes en edad adulta, mujeres y pacientes con diagnóstico de asma. La vacunación completa se asoció con un menor riesgo de reinfección ([OR] 0,05, IC 95% 0,04-0,07; p <0,05) y de desarrollar COVID-19 persistente ([OR] 0,07, IC 95% 0,05-0,10; p <0,05). Ninguno de los pacientes con reinfección o COVID-19 persistente falleció durante el período del estudio. Conclusiones Este estudio confirmó el vínculo entre la edad, el sexo, el asma y el riesgo de COVID-19 persistente. No se pudo definir las comorbilidades del paciente como factor que influye en el desarrollo de reinfección, pero sí se demostró su asociación con edad, sexo e hipertensión arterial. Una mayor cobertura de vacunación se asoció a un menor riesgo de COVID-19 persistente o reinfección por SARS-CoV-2 (AU)

RESUMO

OBJECTIVE: To analyze the frequency of influenza and SARS-CoV-2 co-infections, as well as the differences in the course of disease (risk of mortality, hospital and intensive care admissions) in patients infected with the SARS-CoV-2 virus in relation to flu vaccination status in the 2021-2022 season. METHODS: Population-based observational retrospective study in a cohort of 19,850 patients diagnosed with COVID-19 between June 1, 2021 and February 28, 2022 on the island of Gran Canaria. RESULTS: A total of 1,789 patients (9%) diagnosed with COVID-19 had received flu vaccinations. 13,676 people (68.9%) had a full course of COVID-19 vaccinations. In the period between June 1, 2021 and February 28, 2022, 8 cases of flu and COVID-19 coinfection were recorded. Hypertension (18.5%), asthma (12.8%) and diabetes (7.2%) were the most frequent comorbidities. There were 147 deaths (0.7%). Older patients ([OR] 1.11 95% CI 1.09-1.13) and people with cancer ([OR] 4.21 95% CI 2.58-6.89) had a higher risk of dying from COVID-19 (p<0.05). Female sex was noted as a protective factor ([OR] 0.61 95% CI 0.40-0.92). CONCLUSIONS: Old age, male sex and cancer were independent prognostic factors for mortality. Three doses of SARS-CoV-2 vaccines and influenza vaccines were highly effective in preventing COVID-19-related deaths and hospital admissions. These findings suggest that flu vaccination can help control the pandemic.

RESUMO

Medical avoidance is common among U.S. adults, and may be emphasized among members of marginalized communities due to discrimination concerns. In the current study, we investigated whether this disparity in avoidance was maintained or exacerbated during the onset of the COVID-19 pandemic. We assessed the likelihood of avoiding medical care due to general-, discrimination-, and COVID-19-related concerns in an online sample (N = 471). As hypothesized, marginalized groups (i.e., non-White race, Latinx/e ethnicity, non-heterosexual sexual orientation, high BMI) endorsed more general- and discrimination-related medical avoidance than majoritized groups. However, marginalized groups were equally likely to seek COVID-19 treatment as majoritized groups. Implications for reducing medical avoidance among marginalized groups are discussed.

RESUMO

In the USA, the COVID-19 pandemic has created challenges beyond the direct consequences of the infection. Because of shifting resources in response to need, many domains within the healthcare sector unrelated to COVID-19 have had interrupted abilities to provide care. In the current study, we focus on preventative sexual health care during the pandemic. In a sample of 511 (mean age = 27.7) people, we examined quantitative data regarding continuation and discontinuation of birth control and PrEP during the pandemic, along with qualitative data illustrating the underlying reasons for participants' (dis)continuation. Results showed that most (92.5%) of birth control users reported continuation of their birth control, with the predominant reasons reported being use for health reasons, long-acting reversible contraceptive use, access to remote healthcare services, and increased vigilance over pregnancy prevention. Conversely, around half (52.6%) of PrEP-using participants reported already discontinuing or planning to discontinue their PrEP regimen. Temporary abstinence and concerns about accessing in-person health care were the predominant reasons for PrEP discontinuation. These results have implications for both researchers and sexual healthcare providers. Disruptions to preventative sexual health care should be considered in ongoing research about patient needs, and healthcare providers may wish to consider particular challenges faced by PrEP users concerning re-start and continuation.

RESUMO

Men are more vulnerable to COVID-19 infections compared to women, but their risk perceptions around COVID-19 are persistently lower. Further, men often engage in less health promotion behavior because self-care in this capacity is seen as weak or less masculine. This combination has consequences for mortality; thus, a better understanding of men's COVID-19 cognitions and individual difference factors is critical. In a web-based survey conducted during the beginning stages of the pandemic in the U.S., we collected risk perceptions of various sexual and non-sexual behaviors from heterosexual (n = 137) and gay/bisexual men (n = 108). There were no significant sexual orientation differences for perceptions of COVID-19 risk from routine activities or in overall risk estimates. However, gay/bisexual men did report engaging in more precautionary behavior while socializing (i.e., masking, social distancing) and reported higher risk perceptions than did heterosexual men for nearly all intimate and sexual activities. A more nuanced understanding of cognitions around COVID-19 is needed to better understand motivation for-and especially motivation against-pursuing vaccinations and continuing precautionary behavior.

RESUMO

The incidence of mediastinal teratomas is low, it's important to recognize them between all the differential diagnoses for mediastinal tumors. The treatment is surgical resection. We report a giant mature cystic teratoma of the mediastinum in a 40-year-old woman. She presented with dyspnea, flu-like symptoms during the previous 5 days. An x-ray complemented with a chest CT scan showed a heterogeneous extrapulmonary multiloculated and predominantly fluid density tumor located at the left side of the mediastinum. The patient underwent resection by video-assisted thoracic surgery (VATS). The tumor was 15 cm in diameter with a predominant cystic component. Histologic examination revealed a mature cystic teratoma. Treatment of these tumors should attempt a complete resection. Open approaches are painful, require a longer recovery and are associated with higher morbidity. VATS has been used to treat these tumors, demonstrating the same effectiveness and advantages over open procedures.

RESUMO

Multimodal imaging is an active branch of research as it has the potential to improve common medical imaging techniques. Diffuse optical tomography (DOT) is an example of a low resolution, functional imaging modality that typically has very low resolution due to the ill-posedness of its underlying inverse problem. Combining the functional information of DOT with a high resolution structural imaging modality has been studied widely. In particular, the combination of DOT with ultrasound (US) could serve as a useful tool for clinicians for the formulation of accurate diagnosis of breast lesions. In this paper, we propose a novel method for US-guided DOT reconstruction using a portable time-domain measurement system. B-mode US imaging is used to retrieve morphological information on the probed tissues by means of a semi-automatical segmentation procedure based on active contour fitting. A two-dimensional to three-dimensional extrapolation procedure, based on the concept of distance transform, is then applied to generate a three-dimensional edge-weighting prior for the regularization of DOT. The reconstruction procedure has been tested on experimental data obtained on specifically designed dual-modality silicon phantoms. Results show a substantial quantification improvement upon the application of the implemented technique. This article is part of the theme issue 'Synergistic tomographic image reconstruction: part 2'.

RESUMO

Body weight is often viewed as personally controllable. This belief, however, ignores the complex etiology of body weight. While such attributions of personal willpower may help some individuals regulate their eating patterns, they have also been associated with increased internalized weight stigma which, itself, is associated with more disinhibited eating. The current investigation aimed to examine how internalized weight stigma, along with BMI, may explain the effect of weight controllability beliefs on disparate dietary behaviors. A community sample of 2702 U.S. adults completed an online survey about their weight controllability beliefs, eating behaviors, and internalized weight stigma, as well as demographic items and self-reported BMI. Results showed that greater weight controllability beliefs were positively related to both more restricted eating, ß = 0.135, p < .001, and more disinhibited eating, ß = 0.123, p < .001. This ironic effect was partially explained by increased internalized weight stigma. Moreover, BMI moderated the relationship, such that individuals with lower weights demonstrated stronger effects for two of the three eating outcomes than those with higher weights. These findings advance our understanding of the relationship between attributions of personal control for body weight and subsequent health behaviors, and further underscore the need to target internalized weight stigma in dietary interventions.

RESUMO

Fast time-gated single-photon detectors demonstrated high depth sensitivity in the detection of localized absorption perturbations inside scattering media, but their use for in vivo clinical applications-such as functional imaging of brain activation-was impaired by their small (<0.04mm2) active area. Here, we demonstrate, both on phantoms and in vivo, the performance of a fast-gated digital silicon photomultiplier (SiPM) that features an overall active area of 8.6mm2, overcoming the photon collection capability of established time-gated single-pixel detectors by orders of magnitude, enabling deep investigations within scattering media and high signal-to-noise ratios at late photon arrival times.

RESUMO

Two main bottlenecks prevent time-domain diffuse optics instruments to reach their maximum performances, namely the limited light harvesting capability of the detection chain and the bounded data throughput of the timing electronics. In this work, for the first time to our knowledge, we overcome both those limitations using a probe-hosted large area silicon photomultiplier detector coupled to high-throughput timing electronics. The system performances were assessed based on international protocols for diffuse optical imagers showing better figures with respect to a state-of-the-art device. As a first step towards applications, proof-of-principle in-vivo brain activation measurements demonstrated superior signal-to-noise ratio as compared to current technologies.

RESUMO

Resumen Introducción y objetivos: La Insuficiencia Cardíaca (IC) es un síndrome frecuente en la población adulta. Sacubitril / Valsartán (S/V) es un tratamiento novedoso para esta patología. El presente estudio pretende analizar el efecto de este medicamento sobre las variables clínicas, de laboratorio y ecocardiográficas en pacientes con IC con FEVIr. Metodología: Se realizó un estudio observacional retrospectivo de los expedientes de los pacientes del PIC que tuvieran prescrito S/V. De estos, se recopilaron datos basales y de seguimiento de los principales parámetros de relevancia pronóstica, para estos pacientes. Luego se cuantificaron los cambios generados en el tiempo una vez establecido el tratamiento y se hicieron análisis estadísticos para validar si los cambios fueron significativos. Resultados: De la totalidad de pacientes del PIC, 27 cumplieron los criterios de inclusión, con una edad promedio de 70 años y en donde 37.0% se encontraron en la dosis meta después de un seguimiento promedio de 16.4 meses. A través del estudio fue posible encontrar una diferencia estadísticamente significativa para el cambio en la FEVI para 17 pacientes (p=0.016). En los pacientes en los que se pudo recopilar la información se observó que el NT-proBNP mejoró en un 68.75%, por su parte la caminata de 6 minutos mejoró en un 77.8%. Además, solamente 7.4% de los pacientes empeoraron en su escala funcional NYHA, 7.4% fallecieron y 3.7% sufrieron hospitalización durante el estudio. Conclusiones: Basados en los parámetros estudiados y a través de los cambios generados durante el tiempo de seguimiento, fue posible definir una mejoría en los pacientes tras el uso de S/V, asociado también a una baja mortalidad e incidencia de hospitalizaciones.


Abstract Effect of Sacubitril / Valsartan on the clinical, laboratory and echocardiographic variables used for the control of heart failure with reduced left ventricular ejection fraction (LVEFr) in active patients of the Heart Failure Program (HFP) of the Hospital Clínica Bíblica Introduction and objectives: Heart failure (HF) is a common syndrome in the adult population. Sacubitril /Valsartan (S/V) is a novel treatment for this pathology. This study aims to analyze the effect of this medication on clinical, laboratory and echocardiographic variables in patients with HF and left ventricular eyección fracción reduced (LVEFr). Methodology: A retrospective observational study was conducted on patients records who are enrolled in the Heart Failure Program (HFP) and have been prescribed with S/V. For these patients, baseline and follow-up data was collected for relevant parameters. Changes over time were then quantified once the treatment with S/V was initiated, and a statistical analysis was conducted to validate whether the changes were significant. Results: Of all HFP patients, 27 met the inclusion criteria, with an average age of 70 years and where 37.0% of them were at the target dose after an average follow- up of 16.4 months. Through the study it was possible to find a statistically significant difference in a change for the ejection fraction in 17 patients (p.0.016). In patients with available clinical data, it was observed that NT-proBNP improved by 68.75%, meanwhile the 6-minute walk improved by 77.8%. In addition, only 7.4% of patients worsened their NYHA functional scale, 3.7% were hospitalized and 7.4% died during the time. Conclusions: Based on the studied parameters and throughout all the clinical changes during the follow-up time, it was possible to establish an improvement in patients after the S/V therapy, which is also associated with a low hospitalization incidence and a low mortality rate.

RESUMO

ANTECEDENTES: España ha sido uno de los países más afectados por la pandemia de COVID-19. OBJETIVO: Crear un registro de pacientes hospitalizados en España por COVID-19 para mejorar nuestro conocimiento sobre los aspectos clínicos, diagnósticos, terapéuticos y pronósticos de esta enfermedad. MÉTODOS: Estudio de cohorte retrospectiva, multicéntrico, que incluye pacientes consecutivos hospitalizados con COVID-19 confirmada en toda España. Se obtuvieron los datos epidemiológicos y clínicos, las pruebas complementarias al ingreso y a los 7 días de la admisión, los tratamientos administrados y la evolución a los 30 días de hospitalización de las historias clínicas electrónicas. RESULTADOS: Hasta el 30 de junio de 2020 se incluyeron 15.111 pacientes de 150 hospitales. Su mediana de edad fue 69,4 años (rango: 18-102 años) y el 57,2% eran hombres. Las prevalencias de hipertensión, dislipemia y diabetes mellitus fueron 50,9%, 39,7% y 19,4%, respectivamente. Los síntomas más frecuentes fueron fiebre (84,2%) y tos (73,5%). Fueron frecuentes los valores elevados de ferritina (73,5%), lactato deshidrogenasa (73,9%) y dímero D (63,8%), así como la linfopenia (52,8%). Los fármacos antivirales más utilizados fueron la hidroxicloroquina (85,6%) y el lopinavir/ritonavir (61,4%). El 33,1% desarrolló distrés respiratorio. La tasa de mortalidad global fue del 21,0%, con un marcado incremento con la edad (50-59 años: 4,7%; 60-69 años: 10,5%; 70-79 años: 26,9%; ≥80 años: 46%). CONCLUSIONES: El Registro SEMI-COVID-19 proporciona información sobre las características clínicas de los pacientes con COVID-19 hospitalizados en España. Los pacientes con COVID-19 hospitalizados en España son en su mayoría casos graves, ya que uno de cada 3 pacientes desarrolló distrés respiratorio y uno de cada 5 pacientes falleció. Nuestros datos confirman una estrecha relación entre la edad avanzada y la mortalidad


BACKGROUND: Spain has been one of the countries most affected by the COVID-19 pandemic. OBJECTIVE: To create a registry of patients with COVID-19 hospitalized in Spain, in order to improve our knowledge of the clinical, diagnostic, therapeutic, and prognostic aspects of this disease. METHODS: A multicentre retrospective cohort study, including consecutive patients hospitalized with confirmed COVID-19 throughout Spain. Epidemiological and clinical data, additional tests at admission and at seven days, treatments administered, and progress at 30 days of hospitalization were collected from electronic medical records. RESULTS: Up to June 30th 2020, 15,111 patients from 150 hospitals were included. Their median age was 69.4 years (range: 18-102 years) and 57.2% were male. Prevalences of hypertension, dyslipidemia, and diabetes mellitus were 50.9%, 39.7%, and 19.4%, respectively. The most frequent symptoms were fever (84.2%) and cough (73.5%). High values of ferritin (73.5%), lactate dehydrogenase (73.9%), and D-dimer (63.8%), as well as lymphopenia (52.8%), were frequent. The most used antiviral drugs were hydroxychloroquine (85.6%) and lopinavir/ritonavir (61.4%); 33.1% developed respiratory distress. Overall mortality rate was 21.0%, with a marked increase with age (50-59 years: 4.7%, 60-69 years: 10.5%, 70-79 years: 26.9%, ≥80 years: 46.0%). CONCLUSIONS: The SEMI-COVID-19 Network provides data on the clinical characteristics of patients with COVID-19 hospitalized in Spain. Patients with COVID-19 hospitalized in Spain are mostly severe cases, as one in three patients developed respiratory distress and one in five patients died. These findings confirm a close relationship between advanced age and mortality

RESUMO

INTRODUCTION: Duchenne muscular dystrophy is a complex disease that requires a multidisciplinary and coordinated approach. Given that therapeutic efforts are centred on improving the quality of life of the patient, the aim of this study is to find out the views of young people and adolescents with Duchenne muscular dystrophy, their families, and health professionals as regards the healthcare provided by the hospital in order to improve their quality of life. METHODS: A qualitative study was conducted using 3 focal groups consisting of patients, families, and healthcare professionals. A thematic guide was prepared, and the information from the interviews was gathered using a sound recorder. In order to analyse the information, the transcriptions were coded and the significant data of each interview were extracted and grouped into various topics. RESULTS/CONCLUSIONS: The main worries of the 3 groups were along the same line. On the one hand, the importance of a coordinated multidisciplinary team in the same unit that provides the integral care. On the other hand, sport as a common interest in these adolescents, and the consideration of a positive relationship between leisure and quality of life, finding that their participation in physiotherapy groups of great use. To achieve this objective, it is necessary to improve the coordination between the hospital and the different groups. The parents also demanded better cover in the social and psychological care offered by the hospital. Lastly, the importance of humanising the care was mentioned (privacy, adapting of structures, transmission of information, sexuality…).
