Perceptions, attitudes, and barriers to obesity management in Spain: Results from the spanish cohort of the international ACTION-IO observation study

The prevalence of obesity is rapidly rising in Spain. The Awareness, Care and Treatment in Obesity Management—An International Observation (ACTION-IO) study (NCT03584191) was an international cross-sectional survey conducted to identify the perceptions, attitudes, behaviors, and barriers to obesity management for people with obesity (PwO) and healthcare professionals (HCPs); results from Spain are presented. In Spain, 1500 PwO (body mass index ≥30 kg/m2 based on self-reported height and weight) and 306 HCPs (in direct patient care for ≥2 years) completed the survey. Fewer PwO (59%) than HCPs (93%) agreed that obesity is a chronic disease. Most PwO (80%) assumed complete responsibility for their own weight loss, whilst 19% of HCPs placed the responsibility on PwO. One-fifth of PwO stated they began struggling with weight before age 15. The mean delay in discussing weight for the first time with an HCP was 6 years. Only 24% of HCPs thought their patients were motivated to lose weight, whilst 45% of PwO reported being motivated. Of the 67% of PwO who had discussed their weight with an HCP in the last 5 years, 66% had been formally diagnosed with obesity. Our Spanish dataset reveals discrepancies in the perceptions and attitudes between PwO and HCPs, thus highlighting the need to improve education about obesity and its clinical management

A road map for remote digital health technology for motor neuron disease

Despite recent and potent technological advances, the real-world implementation of remote digital health technology in the care and monitoring of patients with motor neuron disease has not yet been realized. Digital health technology may increase the accessibility to and personalization of care, whereas remote biosensors could optimize the collection of vital clinical parameters, irrespective of patients’ ability to visit the clinic. To facilitate the wide-scale adoption of digital health care technology and to align current initiatives, we outline a road map that will identify clinically relevant digital parameters; mediate the development of benefit-to-burden criteria for innovative technology; and direct the validation, harmonization, and adoption of digital health care technology in real-world settings. We define two key end products of the road map: (1) a set of reliable digital parameters to capture data collected under free-living conditions that reflect patient-centric measures and facilitate clinical decision making and (2) an integrated, open-source system that provides personalized feedback to patients, health care providers, clinical researchers, and caregivers and is linked to a flexible and adaptable platform that integrates patient data in real time. Given the ever-changing care needs of patients and the relentless progression rate of motor neuron disease, the adoption of digital health care technology will significantly benefit the delivery of care and accelerate the development of effective treatments

Effectiveness of an mHealth intervention combining a smartphone app and smart band on body composition in an overweight and obese population: Randomized controlled trial (EVIDENT 3 study)

Background: Mobile health (mHealth) is currently among the supporting elements that may contribute to an improvement in health markers by helping people adopt healthier lifestyles. mHealth interventions have been widely reported to achieve greater weight loss than other approaches, but their effect on body composition remains unclear. Objective: This study aimed to assess the short-term (3 months) effectiveness of a mobile app and a smart band for losing weight and changing body composition in sedentary Spanish adults who are overweight or obese. Methods: A randomized controlled, multicenter clinical trial was conducted involving the participation of 440 subjects from primary care centers, with 231 subjects in the intervention group (IG; counselling with smartphone app and smart band) and 209 in the control group (CG; counselling only). Both groups were counselled about healthy diet and physical activity. For the 3-month intervention period, the IG was trained to use a smartphone app that involved self-monitoring and tailored feedback, as well as a smart band that recorded daily physical activity (Mi Band 2, Xiaomi). Body composition was measured using the InBody 230 bioimpedance device (InBody Co., Ltd), and physical activity was measured using the International Physical Activity Questionnaire. Results: The mHealth intervention produced a greater loss of body weight (–1.97 kg, 95% CI –2.39 to –1.54) relative to standard counselling at 3 months (–1.13 kg, 95% CI –1.56 to –0.69). Comparing groups, the IG achieved a weight loss of 0.84 kg more than the CG at 3 months. The IG showed a decrease in body fat mass (BFM; –1.84 kg, 95% CI –2.48 to –1.20), percentage of body fat (PBF; –1.22%, 95% CI –1.82% to 0.62%), and BMI (–0.77 kg/m2, 95% CI –0.96 to 0.57). No significant changes were observed in any of these parameters in men; among women, there was a significant decrease in BMI in the IG compared with the CG. When subjects were grouped according to baseline BMI, the overweight group experienced a change in BFM of –1.18 kg (95% CI –2.30 to –0.06) and BMI of –0.47 kg/m2 (95% CI –0.80 to –0.13), whereas the obese group only experienced a change in BMI of –0.53 kg/m2 (95% CI –0.86 to –0.19). When the data were analyzed according to physical activity, the moderate-vigorous physical activity group showed significant changes in BFM of –1.03 kg (95% CI –1.74 to –0.33), PBF of –0.76% (95% CI –1.32% to –0.20%), and BMI of –0.5 kg/m2 (95% CI –0.83 to –0.19). Conclusions: The results from this multicenter, randomized controlled clinical trial study show that compared with standard counselling alone, adding a self-reported app and a smart band obtained beneficial results in terms of weight loss and a reduction in BFM and PBF in female subjects with a BMI less than 30 kg/m2 and a moderate-vigorous physical activity level. Nevertheless, further studies are needed to ensure that this profile benefits more than others from this intervention and to investigate modifications of this intervention to achieve a global effect

Spread of a SARS-CoV-2 variant through Europe in the summer of 2020.

Following its emergence in late 2019, the spread of SARS-CoV-21,2 has been tracked by phylogenetic analysis of viral genome sequences in unprecedented detail3–5. Although the virus spread globally in early 2020 before borders closed, intercontinental travel has since been greatly reduced. However, travel within Europe resumed in the summer of 2020. Here we report on a SARS-CoV-2 variant, 20E (EU1), that was identified in Spain in early summer 2020 and subsequently spread across Europe. We find no evidence that this variant has increased transmissibility, but instead demonstrate how rising incidence in Spain, resumption of travel, and lack of effective screening and containment may explain the variant’s success. Despite travel restrictions, we estimate that 20E (EU1) was introduced hundreds of times to European countries by summertime travellers, which is likely to have undermined local efforts to minimize infection with SARS-CoV-2. Our results illustrate how a variant can rapidly become dominant even in the absence of a substantial transmission advantage in favourable epidemiological settings. Genomic surveillance is critical for understanding how travel can affect transmission of SARS-CoV-2, and thus for informing future containment strategies as travel resumes. © 2021, The Author(s), under exclusive licence to Springer Nature Limited

A cross-disease meta-GWAS identifies four new susceptibility loci shared between systemic sclerosis and Crohn’s disease

Abstract: Genome-wide association studies (GWASs) have identified a number of genetic risk loci associated with systemic sclerosis (SSc) and Crohn’s disease (CD), some of which confer susceptibility to both diseases. In order to identify new risk loci shared between these two immune-mediated disorders, we performed a cross-disease meta-analysis including GWAS data from 5,734 SSc patients, 4,588 CD patients and 14,568 controls of European origin. We identified 4 new loci shared between SSc and CD, IL12RB2, IRF1/SLC22A5, STAT3 and an intergenic locus at 6p21.31. Pleiotropic variants within these loci showed opposite allelic effects in the two analysed diseases and all of them showed a significant effect on gene expression. In addition, an enrichment in the IL-12 family and type I interferon signaling pathways was observed among the set of SSc-CD common genetic risk loci. In conclusion, through the first cross-disease meta-analysis of SSc and CD, we identified genetic variants with pleiotropic effects on two clinically distinct immune-mediated disorders. The fact that all these pleiotropic SNPs have opposite allelic effects in SSc and CD reveals the complexity of the molecular mechanisms by which polymorphisms affect diseases

Relevancia del síndrome piramidal en la esclerosis lateral amiotrófica

Resumen: Introducción: Los signos piramidales (hiperreflexia, espasticidad, signo de Babinski) son fundamentales para el diagnóstico de esclerosis lateral amiotrófica (ELA). Sin embargo, no siempre están presentes al comienzo, pueden variar con el tiempo y es controvertido su papel en la evolución. El objetivo del estudio es describir qué signos piramidales están presentes inicialmente y cómo evolucionan en una cohorte de pacientes con ELA, así como su papel pronóstico. Métodos: Análisis retrospectivo de pacientes recogidos de manera prospectiva, diagnosticados de ELA en nuestro centro, desde 1990 hasta 2015. Resultados: Del total de 130 pacientes con ELA, 34 (26,1%) no presentaron inicialmente ningún signo piramidal, mientras que 15 (11,5%) presentaban un síndrome piramidal completo. De aquellos pacientes sin piramidalismo inicial, la mediana de aparición de los primeros signos fue de 4,5 meses. El signo de Babinski estaba presente en 64 (49,2%), la hiperreflexia en 90 (69,2%) y en 22 (16,9%) pacientes existía espasticidad. Los signos piramidales tendían a mantenerse inalterados en el tiempo, aunque existe un porcentaje de pacientes en el que aparecen tardíamente o desaparecen con el tiempo.No se encontró asociación entre supervivencia y la presencia o modificación de signos piramidales, aunque la disminución de la espasticidad se asociaba a mayor deterioro clínico (escala ALSFR) (p < 0,001). Conclusión: Una cuarta parte de pacientes con ELA no presentaron inicialmente ningún signo piramidal y, en algunos casos, estos desaparecen con el tiempo. Esto resalta la necesidad de la inclusión de herramientas para la valoración de la vía piramidal. Abstract: Introduction: Pyramidal signs (hyperreflexia, spasticity, Babinski sign) are essential for the diagnosis of amyotrophic lateral sclerosis (ALS). However, these signs are not always present at onset and may vary over time, besides which their role in disease evolution is controversial. Our goal was to describe which pyramidal signs were present and how they evolved in a cohort of patients with ALS, as well as their role in prognosis. Methods: Retrospective analysis of prospectively collected patients diagnosed with ALS in our centre from 1990 to 2015. Results: Of a total of 130 patients with ALS, 34 (26.1%) patients showed no pyramidal signs at the first visit while 15 (11.5%) had a complete pyramidal syndrome. Of those patients without initial pyramidal signs, mean time of appearance of the first signs was 4.5 months. Babinski sign was positive in 64 (49.2%) patients, hyperreflexia in 90 (69.2%) and 22 (16.9%) patients had spasticity. Pyramidal signs tended to remain unchanged over time, although they seem to appear at later stages or even disappear with time in some patients.We found no association between survival and the presence of changes to pyramidal signs, although decreased spasticity was associated with greater clinical deterioration (ALSFR scale) (P<.001). Conclusion: A quarter of patients with ALS initially showed no pyramidal signs and in some cases they even disappear over time. These data support the need for tools that assess the pyramidal tract.
