    A resurgence of COVID-19 infections is occurring in Spain, with some of the worst figures in Europe. In August, 2020, we urged the Spanish Central Government and regional governments to independently evaluate their COVID-19 response to identify areas where public health and the health and social care system need to be improved

    Turner syndrome, a congenital condition that affects ∼1/2,500 births, results from absence or structural alteration of the second sex chromosome. There has been substantial effort by numerous clinical and genetic research groups to delineate the clinical, pathophysiological, cytogenetic, and molecular features of this multisystem condition. Questions about the molecular-genetic and biological basis of many of the clinical features remain unanswered, and health care providers and families seek improved care for affected individuals. The inaugural “Turner Resource Network (TRN) Symposium” brought together individuals with Turner syndrome and their families, advocacy group leaders, clinicians, basic scientists, physician-scientists, trainees and other stakeholders with interest in the well-being of individuals and families living with the condition. The goal of this symposium was to establish a structure for a TRN that will be a patient-powered organization involving those living with Turner syndrome, their families, clinicians, and scientists. The TRN will identify basic and clinical questions that might be answered with registries, clinical trials, or through bench research to promote and advocate for best practices and improved care for individuals with Turner syndrome. The symposium concluded with the consensus that two rationales justify the creation of a TRN: 1. inadequate attention has been paid to the health and psychosocial issues facing girls and women who live with Turner syndrome; 2. investigations into the susceptibility to common disorders such as cardiovascular or autoimmune diseases caused by sex chromosome deficiencies will increase understanding of disease susceptibilities in the general population.Eunice Kennedy Shriver National Institute of Child Health and Human Development (U.S.) (Grant 1R13HD079209-01)March of Dimes Birth Defects FoundationAmerican Heart AssociationNational Institutes of Health (U.S.) Office of Women's HealthLeaping Butterfly MinistryTurner Syndrome Society of the United State

    Mapping Brain Response to Pain in Fibromyalgia Patients Using Temporal Analysis of fMRI

    Background: Nociceptive stimuli may evoke brain responses longer than the stimulus duration often partially detected by conventional neuroimaging. Fibromyalgia patients typically complain of severe pain from gentle stimuli. We aimed to characterize brain response to painful pressure in fibromyalgia patients by generating activation maps adjusted for the duration of brain responses. Methodology/Principal Findings: Twenty-seven women (mean age: 47.8 years) were assessed with fMRI. The sample included nine fibromyalgia patients and nine healthy subjects who received 4 kg/cm2 of pressure on the thumb. Nine additional control subjects received 6.8 kg/cm2 to match the patients for the severity of perceived pain. Independent Component Analysis characterized the temporal dynamics of the actual brain response to pressure. Statistical parametric maps were estimated using the obtained time courses. Brain response to pressure (18 seconds) consistently exceeded the stimulus application (9 seconds) in somatosensory regions in all groups. fMRI maps following such temporal dynamics showed a complete pain network response (sensory-motor cortices, operculo-insula, cingulate cortex, and basal ganglia) to 4 kg/cm2 of pressure in fibromyalgia patients. In healthy subjects, response to this low intensity pressure involved mainly somatosensory cortices. When matched for perceived pain (6.8 kg/cm2), control subjects showed also comprehensive activation of pain-related regions, but fibromyalgia patients showed significantly larger activation in the anterior insula-basal ganglia complex and the cingulate cortex. Conclusions/Significance: The results suggest that data-driven fMRI assessments may complement conventional neuroimaging for characterizing pain responses and that enhancement of brain activation in fibromyalgia patients may be particularly relevant in emotion-related regions

    Novel recombinant mycobacterium bovis BCG, ovine atadenovirus, and modified vaccinia virus ankara vaccines combine to induce robust human immunodeficiency virus-specific CD4 and CD8 T-cell responses in rhesus macaques

    Mycobacterium bovis bacillus Calmette-Guérin (BCG), which elicits a degree of protective immunity against tuberculosis, is the most widely used vaccine in the world. Due to its persistence and immunogenicity, BCG has been proposed as a vector for vaccines against other infections, including HIV-1. BCG has a very good safety record, although it can cause disseminated disease in immunocompromised individuals. Here, we constructed a recombinant BCG vector expressing HIV-1 clade A-derived immunogen HIVA using the recently described safer and more immunogenic BCG strain AERAS-401 as the parental mycobacterium. Using routine ex vivo T-cell assays, BCG.HIVA401 as a stand-alone vaccine induced undetectable and weak CD8 T-cell responses in BALB/c mice and rhesus macaques, respectively. However, when BCG.HIVA401 was used as a priming component in heterologous vaccination regimens together with recombinant modified vaccinia virus Ankara-vectored MVA.HIVA and ovine atadenovirus-vectored OAdV.HIVA vaccines, robust HIV-1-specific T-cell responses were elicited. These high-frequency T-cell responses were broadly directed and capable of proliferation in response to recall antigen. Furthermore, multiple antigen-specific T-cell clonotypes were efficiently recruited into the memory pool. These desirable features are thought to be associated with good control of HIV-1 infection. In addition, strong and persistent T-cell responses specific for the BCG-derived purified protein derivative (PPD) antigen were induced. This work is the first demonstration of immunogenicity for two novel vaccine vectors and the corresponding candidate HIV-1 vaccines BCG.HIVA401 and OAdV.HIVA in nonhuman primates. These results strongly support their further exploration

    La pandemia de COVID-19 ha afectado de manera particularmente intensa a España, pese a su nivel de desarrollo y la elogiada solidez de su Sistema Nacional de Salud. Para comprender qué ha pasado e identificar cómo mejorar la respuesta creemos imprescindible una evaluación independiente multidisciplinaria de la esfera sanitaria, política y socioeconómica. En este trabajo proponemos objetivos, principios, metodología y dimensiones a evaluar, además de esbozar el tipo de resultados y conclusiones esperadas. Nos inspiramos en los requerimientos formulados por el panel independiente de la Organización Mundial de la Salud y en las experiencias evaluativas en otros países, y detallamos la propuesta de aspectos multidimensionales que deben valorarse. La idea es comprender aspectos clave en los ámbitos estudiados y su margen de mejora en lo relativo a preparación, gobernanza, marco normativo, estructuras del Sistema Nacional de Salud (atención primaria, hospitalaria y de salud pública), sector de educación, esquemas de protección social, minimización del impacto económico, y marco y reformas en el ámbito laboral para una sociedad más resiliente. En definitiva, buscamos que este ejercicio sirva no solo para el presente, sino también para que en el futuro estemos mejor preparados y con más ágil capacidad de recuperación ante las amenazas pandémicas que puedan surgir.The COVID-19 pandemic has hit Spain particularly hard, despite being a country with a developed economy and being praised for the robustness of its national health system. In order to understand what happened and to identify how to improve the response, we believe that an independent multi-disciplinary evaluation of the health, political and socio-economic spheres is essential. In this piece we propose objectives, principles, methodology and dimensions to be evaluated, as well as outlining the type of results and conclusions expected. Inspired by the requirements formulated by the WHO Independent Panel for Pandemic Preparedness and Response and by experiences in other countries, we detail the multidimensional aspects to be evaluated. The goal is to understand key aspects in the studied areas and their scope for improvement in terms of preparedness, governance, regulatory framework, national health system structures (primary care, hospital, and public health), education sector, social protection schemes, minimization of economic impact, and labour framework and reforms for a more resilient society. We seek to ensure that this exercise serves not only at present, but also that in the future we are better prepared and more agile in terms of our ability to recover from any pandemic threats that may arise.Ayuda referencia: PI 18/01937 del Fondo de Investigación Sanitaria- Instituto de Salud Carlos III, España, con cofinanciación de Fondos FEDER

    Therapeutic inertia amongst general practitioners with interest in diabetes

    Introduction As the therapeutic options in the management of type 2 diabetes increase, there is an increase confusion among health care professionals, thus leading to the phenomenon of therapeutic inertia. This is the failure to escalate or de-escalate treatment when the clinical need for this is required. It has been studied extensively in various settings, however, it has never been reported in any studies focusing solely on primary care physicians with an interest in diabetes. This group is increasingly becoming the focus of managing complex diabetes care in the community, albeit with the support from specialists. Methods In this retrospective audit, we assessed the prevalence of the phenomenon of therapeutic inertia amongst primary care physicians with an interest in diabetes in UK. We also assessed the predictive abilities of various patient level characteristics on therapeutic inertia amongst this group of clinicians. Results Out of the 240 patients reported on, therapeutic inertia was judged to have occurred in 53 (22.1%) of patients. The full model containing all the selected variables was not statistically significant, p = 0.59. So the model was not able to distinguish between situations in which therapeutic inertia occurred and when it did not occur. None of the patient level characteristics on its own was predictive of therapeutic inertia. Conclusion Therapeutic inertia was present only in about a fifth of patient patients with diabetes being managed by primary care physicians with an interest in diabetes
