Defining well-being in psoriasis: A Delphi consensus among healthcare professionals and patients.

Psoriasis is a chronic skin disease that negatively impacts on patient's life. A holistic approach integrating well-being assessment could improve disease management. Since a consensus definition of well-being in psoriasis is not available, we aim to achieve a multidisciplinary consensus on well-being definition and its components. A literature review and consultation with psoriasis patients facilitated the design of a two-round Delphi questionnaire targeting healthcare professionals and psoriasis patients. A total of 261 panellists (65.1% patients with psoriasis, 34.9% healthcare professionals) agreed on the dimensions and components that should integrate the concept of well-being: emotional dimension (78.9%) [stress (83.9%), mood disturbance (85.1%), body image (83.9%), stigma/shame (75.1%), self-esteem (77.4%) and coping/resilience (81.2%)], physical dimension (82.0%) [sleep quality (81.6%), pain/discomfort (80.8%), itching (83.5%), extracutaneous manifestations (82.8%), lesions in visible areas (84.3%), lesions in functional areas (85.8%), and sex life (78.2%)], social dimension (79.5%) [social relationships (80.8%), leisure/recreational activities (80.3%), support from family/friends (76.6%) and work/academic life (76.5%)], and satisfaction with disease management (78.5%) [treatment (78.2%), information received (75.6%) and medical care provided by the dermatologist (80.1%)]. This well-being definition reflects patients' needs and concerns. Therefore, addressing them in psoriasis will optimise management, contributing to better outcomes and restoring normalcy to the patient's life.

Evaluating the Impact of a Training Program in Shared Decision-Making for Neurologists Treating People with Migraine.

INTRODUCTION: Migraine symptoms vary significantly between patients and within the same patient. Currently, an increasing number of therapeutic options are available for symptomatic and preventive treatment. Guidelines encourage physicians to use shared decision-making (SDM) in their practice, listening to patients' treatment preferences in order to select the most suitable and effective therapy. Although training for healthcare professionals could increase their awareness of SDM, results concerning its effectiveness are inconclusive. This study aimed to analyze the impact of a training activity to promote SDM in the context of migraine care. This was addressed by evaluating the impact on patients' decisional conflict (main objective), patient-physician relationship, neurologists' perceptions of the training and patient's perception of SDM. METHODS: A multicenter observational study was conducted in four highly specialized headache units. The participating neurologists received SDM training targeting people with migraine in clinical practice to provide techniques and tools to optimize physician-patient interactions and encourage patient involvement in SDM. The study was set up in three consecutive phases: control phase, in which neurologists were blind to the training activity and performed the consultation with the control group under routine clinical practice; training phase, when the same neurologists participated in the SDM training; and SDM phase, in which these neurologists performed the consultation with the intervention group after the training. Patients in both groups with a change of treatment assessment during the visit completed the Decisional conflict scale (DCS) after the consultation to measure the patient's decisional conflict. Also, patients answered the patient-doctor relationship questionnaire (CREM-P) and the 9-item Shared Decision-Making Questionnaire (SDM-Q-9). The mean ± SD scores obtained from the study questionnaires were calculated for both groups and compared to determine whether there were significant differences (p < 0.05). RESULTS: A total of 180 migraine patients (86.7% female, mean age of 38.5 ± 12.3 years) were included, of which 128 required a migraine treatment change assessment during the consultation (control group, n = 68; intervention group, n = 60). A low decisional conflict was found without significant differences between the intervention (25.6 ± 23.4) and control group (22.1 ± 17.9; p = 0.5597). No significant differences in the CREM-P and SDM-Q-9 scores were observed between groups. Physicians were satisfied with the training and showed greater agreement with the clarity, quality and selection of the contents. Moreover, physicians felt confident communicating with patients after the training, and they applied the techniques and SDM strategies learned. CONCLUSION: SDM is a model currently being actively used in clinical practice for headache consultation, with high patient involvement in the process. This SDM training, while useful from the physician's perspective, may be more effective at other levels of care where there is still room for optimization of patient involvement in decision-making.

Antecedentes y objetivo: Disponer de datos epidemiológicos y de carga de una enfermedad es crucial para su control y óptima planificación. El objetivo es estimar la carga de la psoriasis en términos epidemiológicos, las comorbilidades asociadas, el uso de recursos sanitarios y la incapacidad laboral. Material y método: Se han analizado los datos de la encuesta de salud de Cataluña (ESCA) del 2016, el registro de morbilidad y utilización de servicios sanitarios de Cataluña (MUSSCAT) del 2016 y los datos recopilados entre el 2012 y el 2016 del sistema integrado de gestión de la incapacidad temporal (IT) del Instituto Catalán de Evaluaciones Médicas. Resultados:La prevalecía de la psoriasis en Cataluña con base en los datos de la ESCA se sitúa en el 1,8%. Los datos del MUSSCAT muestran que el número de casos incidentes se ha mantenido estable en los últimos años. Las comorbilidades más frecuentes en el paciente con psoriasis son la hipertensión arterial (35%) y la diabetes (15%). La estratificación de la población con psoriasis por niveles de riesgo situó al 40% en riesgo moderado-alto. El uso anual de recursos sanitarios de las personas con psoriasis es elevado (8,7 visitas de atención primaria; 2,8 consultas externas; 0,5 de urgencias y hospital de día; 0,2 de salud mental y 6,1 medicamentos). Los procesos de IT asociados con la psoriasis o artropatía psoriásica representaron el 0,04% del total de registros. Conclusiones: La prevalencia de la psoriasis en Cataluña es del 1,8%. La carga de la enfermedad es elevada, tanto en términos de comorbilidades del paciente como en el requerimiento del uso de recursos (AU)

Background and objectives: Epidemiologic and disease burden data are essential for disease control and optimal health care resource planning. The aims of this study were to estimate the epidemiologic burden of psoriasis and evaluate associated comorbidities, health care utilization, and sick leave. Material and methods: We collected data from the 2016 Catalan Health Survey (ESCA), the Catalan Registry of Morbidity and Utilization of Health Care Services (MUSSCAT) (2016), and the database of the Catalan Medical Evaluations Institute (ICAM) (2012–2016). Results: The prevalence of psoriasis in Catalonia according to 2016 ESCA data is approximately 1.8%. The MUSSCAT registry data indicate that the incidence has remained stable in recent years. The most common comorbidities associated with psoriasis are hypertension (35%) and diabetes (15%). Forty percent of patients with psoriasis have a moderate to high risk for death or high health resource utilization. Annual use of resources by psoriasis patients is high: they make a mean of 8.7 primary care visits, 2.8 outpatient visits, 0.5 emergency and day hospital visits, 0.2 mental health visits, and use 6.1 medications. Sick leave due to psoriasis or psoriatic arthritis accounted for 0.04% of all cases. Conclusions:The prevalence of psoriasis in Catalonia is high at 1.8%. The disease burden is also high, both in terms of comorbidities and health care utilization (AU)

The view of experts on initiatives to be undertaken to promote equity in the access to orphan drugs and specialised care for rare diseases in Spain: A Delphi consensus.

OBJECTIVES: To reach a consensus amongst experts on the most feasible actions to be undertaken to facilitate patient access to specialised care and orphan drugs (OD) in the public health sector in Spain. METHODS: Two Delphi rounds were completed. The questionnaire was based on a literature review and 2 focus groups. Agreement was sought on the desire (D) and prognosis (P) for the implementation within the next 5 years, on a 5-point Likert scale. Consensus was reached when ≥75% participants chose agreement (1-2) or disagreement options (4-5). RESULTS: 82 experts on rare disease (RD) participated. Agreement on the D and P was reached in 66.07% statements: OD pricing review [absence of clinical effectiveness (D:85.37%; P:85.90%), target population increase (D:79.27%; P:91.03%)]; reference team definition of referral protocols and clinical practice guidelines (D: 97.56%; P: 89.74%); and a unified, usable, etiology-based registry (D:97.56%; P:84.62%). D and P assessment diverged in 32.14% items: creation of a specific funding system for OD (D: 97.56%; P: 60.25%); and a network of medical teams to coordinate the care of RD patients (D: 99%; P: 62%). CONCLUSIONS: The results have shown the need to promote dialogue between stakeholders, introduce European recommendation to national and regional Spanish policies and set up priorities and undertake actions to drive relevant changes in current medical practice in managing RD patients.

Analysis of the implementation of a personalized care model in diabetes mellitus as an example of chronic disease with information and communication technology support.

INTRODUCTION: Diabetes mellitus affects 13.8% of the adult population in Spain, representing some 8.2% of total Spanish health spending, which may be reduced by optimizing treatment and disease monitoring. Areas covered: This perspective article aims to evaluate the possible clinical and economic outcomes of implementing a theoretical personalized care model in diabetes supported by information and communications technology in Spain vs. conventional care. Moreover, we assessed the value of emminens® eConecta, a solution designed to support the operational implementation of this model, which enables the connection and participation of patients and health professionals, facilitates patient education, decision-making, access to information, and data analysis. We carried out a review of the available evidence, consultations with experts and a clinical and cost estimation. Expert commentary: The experts consulted considered that the proposed model is consistent with Spanish strategies on chronicity, supports the management of chronicity/diabetes, and may improve the most important aspects of disease management. In the literature, this type of care models improved or provided equal disease control compared with conventional care, potentiated self-management strategies and reduced the high use of resources. Cost estimation showed a reduction of -12% in total direct costs and around -34% in the costs of outpatient visits.

Adherence, satisfaction and preferences for treatment in patients with psoriasis in the European Union: a systematic review of the literature.

BACKGROUND AND OBJECTIVE: Adherence to treatment in patients with psoriasis is often poor. An investigation of patient preferences and satisfaction with treatment may be important, based on the expected correlation with therapy compliance. This paper aims to examine and describe the current literature on patient preferences, satisfaction and adherence to treatment for psoriasis in the European Union (EU). METHODS: Electronic searches were conducted using PubMed, ISI Web of Knowledge, Scopus, Spanish databases and Google Scholar. European studies published in English or Spanish between January 1, 2009 and December 31, 2014 regarding patient-reported outcomes in psoriatic patients were included. Studies conducted in non-EU countries, letters to the editor, editorials, experts' opinions, case studies, congress proceedings, publications that did not differentiate between patients with psoriasis and psoriatic arthritis or studies related to specific treatment were excluded. RESULTS: A total of 1,769 titles were identified, of which 1,636 were excluded as they were duplicates or did not provide any relevant information. After a full-text reading and application of the inclusion/exclusion criteria, 46 publications were included. This paper will describe publications on adherence (n=4), preferences (n=5) and satisfaction with treatment (n=7). Results related to health-related quality of life articles (n=30) have been published elsewhere. Adherence rates are generally low in psoriasis patients regardless of the type of treatment, severity of disease or methods used to measure adherence. Biologic therapy is associated with greater clinical improvement. There is a direct association between physician recommendations, patient preferences and several domains of treatment satisfaction. CONCLUSION: The results of this review support the conclusion that adherence rates in patients with psoriasis are suboptimal and highlight the need to improve patient compliance and satisfaction with treatment. Patients' preferences should be taken into account in the treatment decision-making process in order to improve patients' clinical outcomes by ensuring satisfaction and adherence.

Beneficios del uso de un dispositivo de gestión de datos del glucómetro en el seguimiento de pacientes con diabetes tipo 2 en atención primaria: estudio TRANSFER / Usefulness of a blood glucose meter device reader in the management of patients with diabetes mellitus type 2 in primary care settings: the TRANSFER Study

OBJETIVO: El objetivo del estudio fue valorar la percepción del profesional de la enfermería sobre los beneficios del uso de un dispositivo (Accu-Chek(R) Smart Pix) para gestionarlos datos del glucómetro en el manejo de la diabetes tipo 2 (DT2) en consultas de atención primaria en España. MATERIAL Y MÉTODO: Estudio observacional prospectivo con un periodo de seguimiento de6 meses. Los beneficios de gestionar el control de la glucemia se evaluaron mediante escalas Likert. Además, se analizaron los cambios en las variables de control metabólico y en las recomendaciones para el control de la glucemia a lo largo del estudio. RESULTADOS: Se reclutaron 257 pacientes de 32 centros de atención primaria. El personal de enfermería consideró útil el dispositivo en el 91% de los pacientes, y en casi todos los casos estaba satisfecho con su uso. Los pacientes mejoraron su actitud respecto al tratamiento al final del estudio. Aumentó la proporción de pacientes que midieron su glucosa capilar después de la cena (p = 0,0170) y la proporción de pacientes a los que se les cambió el tratamiento (p = 0,0006). El porcentaje de hemoglobina glucosilada (HbA1c) disminuyó del 8,33% en la visita basal al 7,64% en la última visita del estudio (p < 0,0001).CONCLUSIONES: El dispositivo demostró ser útil en el manejo de pacientes con DT2 tratados con insulina en consultas de atención primaria. Además, se observó una mejora en los niveles de HbA1c

OBJECTIVES: The objective of this study was to evaluate the opinion of nurses on the benefits of the use of a device to manage type 2 diabetes mellitus (T2DM) in primary care centres in Spain. MATERIALS AND METHODS: A non-interventional, multicentre, prospective study was conducted with a 6-month of follow-up. The benefits of managing blood glucose control with the device were assessed using Likert scales. As well as the changes in the glycaemic control, an assessment was made of the variables and recommendations for modifying self-monitoring of blood glucose. RESULTS: A total of 257 patients were recruited in 32 primary care centres. The nurses considered the device reader useful or very useful in 91% of patients, and almost in all cases the nurses were satisfied with its use. At the end of the study, patients improved their attitude towards the diabetes therapy. The proportion of patients who measured their blood glucose levels after dinner and in whom their treatment was modified, increased during the study (P = .0170 and P = .0006, respectively). The percentage of glycosylated haemoglobin (HbA1c) decreased from 8.33% at baseline to 7.64% at the end of the study (P < 0001). CONCLUSIONS: The device reader was useful in the management of patients with T2DM treated with insulin in primary care centres. Moreover, an improvement in HbA1c levels was observed

Viral isolation from cases of epidemic neuropathy in Cuba.

OBJECTIVE: To investigate the possibility of a viral agent in the central nervous system of patients with epidemic neuropathy. DESIGN: Virus isolation attempts, in cell cultures and suckling mice, from cerebrospinal fluid (CSF) of neuropathy patients and controls undergoing lumbar puncture for unrelated reasons. Serologic studies in patients, contacts, and controls. SETTING: An epidemic of optic and peripheral neuropathy affected more than 50,000 people in Cuba in 1991 through 1993. Illness was associated with dietary limitations and increased physical demands accompanying the shortages of food and fuel experienced in Cuba since 1989. Most patients responded to parenteral vitamin therapy, and the epidemic began to subside when oral vitamin supplementation was begun for the entire Cuban population. RESULTS: Coxsackievirus A9 (five isolates) and a similar, less cytopathic virus (100 isolates) were recovered from 105 (84%) of 125 CSF specimens from neuropathy patients. The strains with light cytopathic effect were antigenically related to Coxsackieviruses A9 and B4 by cross-neutralization and immunoblotting assays. Virus persisted in CSF of some patients for 1 to 12 months. Cerebrospinal fluid from patients and both types of virus from cell culture produced illness, including complete posterior flaccid paralysis, in newborn mice, and virus was reisolated from the mice. Mouse tissues and sural nerve biopsy specimens from patients were stained by immunoperoxidase and colloidal gold techniques using hyperimmune rabbit antisera against the virus with light cytopathic effect. CONCLUSIONS: Coxsackievirus A9 or an antigenically related agent with a light cytopathic effect was present in CSF of 84% of 125 patients with epidemic neuropathy. The role of these agents, probably in combination with nutritional factors, in the pathophysiology of the disease requires further investigation.

Massive pleural effusion as isolated manifestation of metastatic spread of salivary adenoid cystic carcinoma.

Adenoid cystic carcinoma is a low-grade malignant neoplasm that arises preferentially in the major and/or minor salivary glands. While it has a tendency to spread locally, distant metastases have been described occasionally. This case report describes a patient with a massive pleural effusion as primary manifestation of metastatic adenoid cystic carcinoma. This is a very uncommon, yet treatable, occurrence.

Lessons from Cuba: mass campaign administration of trivalent oral poliovirus vaccine and seroprevalence of poliovirus neutralizing antibodies.

The immunogenicity of trivalent oral poliovirus vaccine (TOPV), which is less effective in tropical than in temperate areas, may potentially be improved in several ways, including increasing the number of doses. Little information is available on TOPV when more than 6 doses are given. The situation in Cuba provides a unique opportunity to relate the seroprevalence of neutralizing antibodies to the dose of TOPV because Cuba has not reported culture-confirmed poliomyelitis since 1973 and TOPV is only administered in twice yearly 1-week mass immunization campaigns. Sera from 2000 children nationwide were studied for neutralizing antibody among children who received 0, 2, 4, 6 and 8 doses of TOPV. These doses were administered in the period 1989-91, when TOPV (from the USSR) was being used with 500,000, 200,000, and 300,000 median tissue-culture-infecting doses (TCID50) for types 1, 2 and 3, respectively--the 5:2:3 formulation. Seroprevalence of neutralizing antibody after two TOPV doses was 91.5% for type 1, 90.8% for type 2, and 45.9% for type 3. Seroprevalence of type-3 neutralizing antibody after 6 doses remained low (73.4%), but increased to 83.5% after 8 doses (P < 0.05). Although 16.5% of the children remained unprotected for type-3 infection even after 8 doses, mass campaign immunization strategies were sufficient to eradicate the transmission of wild poliovirus in Cuba. Because the seroprevalence of type-1 neutralizing antibody was high (91.5%) after two campaign doses, additional studies using different formulations are needed to determine whether simultaneous improvement in the type-3 response to two campaign doses can be achieved.

PIP: During December 1991-January 1992 in Cuba, health workers took blood samples from a nationwide sample of 2000 children aged 0-3 who received 0, 2, 4, 6, and 8 doses of trivalent oral poliovirus vaccine (TOPV) to determine the seroprevalence of poliovirus neutralizing antibodies for types 1, 2, and 3. Specifically, researchers wanted to learn whether TOPV becomes more effective as the number of doses increases. Since 1973, Cuba has conducted two mass immunization campaigns each year in February and April. During 1970-91, Cuba used a USSR-produced poliovirus vaccine that had 500,000, 200,000, and 300,000 median tissue-culture-infecting doses for types 1, 2, and 3, respectively. Wild poliovirus has not been transmitted in Cuba since 1973 (as of August 1993), indicating that the mass immunization campaigns without routine vaccine delivery have eradicated poliomyelitis in Cuba. The seroprevalence of poliovirus neutralizing antibodies for type 1 increased significantly between 2 and 4 doses (91.5% vs. 96.5%; p = 0.05), thereafter the increases were small and insignificant. The seroprevalence of poliovirus neutralizing antibodies for type 2 increased significantly between 2 and 4 doses (90.8% vs. 97.2%), with small insignificant increases thereafter. Two doses of TOPV induced a response against poliovirus type 3 in only 45.9% of cases. At 4 doses and 8 doses, it did increase significantly from the previous dose (71.2% and 83.5%, respectively; p 0.05). Further studies using other vaccine formulations would allow persons involved in global eradication efforts to determine whether two campaign doses can improve the immunogenicity of the type 3 poliovirus while also improving that of the type 1 poliovirus.
