Upadacitinib for moderate-to-severe atopic dermatitis: Stratified analysis from three randomized phase 3 trials by key baseline characteristics.

BACKGROUND: Atopic dermatitis (AD) is a heterogeneous inflammatory skin disease with different clinical phenotypes based on factors such as age, race, comorbidities, and clinical signs and symptoms. The effect of these factors on therapeutic responses in AD has only been scarcely studied and not for upadacitinib. Currently, there is no biomarker predicting response to upadacitinib. OBJECTIVES: Evaluate the efficacy of the oral Janus kinase inhibitor upadacitinib across patient subgroups (baseline demographics, disease characteristics and prior treatment) in patients with moderate-to-severe AD. METHODS: Data from phase 3 studies (Measure Up 1, Measure Up 2 and AD Up) were utilized for this post hoc analysis. Adults and adolescents with moderate-to-severe AD were randomized to receive once daily oral upadacitinib 15 mg, upadacitinib 30 mg or placebo; patients enrolled in the AD Up study received concomitant topical corticosteroids. Data from the Measure Up 1 and Measure Up 2 studies were integrated. RESULTS: A total of 2584 patients were randomized. A consistently greater proportion of patients achieved at least 75% improvement in the Eczema Area and Severity Index, a 0 or 1 on the validated Investigator Global Assessment for Atopic Dermatitis, and improvement in itch (including an achievement of a reduction of ≥4; and score of 0/1 in Worst Pruritus Numerical Rating Scale) with upadacitinib compared with placebo at Week 16, regardless of age, sex, race, body mass index, AD severity, body surface area involvement, history of atopic comorbidities or asthma, or previous exposure to systemic therapy or cyclosporin. CONCLUSIONS: Upadacitinib had consistently high skin clearance rates and itch efficacy across subgroups of patients with moderate-to-severe AD through Week 16. These results support upadacitinib as a suitable treatment option in a variety of patients. TRIAL REGISTRATION: ClinicalTrials.gov Identifiers: NCT03569293 (Measure Up 1), NCT03607422 (Measure Up 2) and NCT03568318 (AD Up).

Cognitive Functioning in Adults with Phenylketonuria in a Cohort of Spanish Patients.

The early introduction of a low phenylalanine (Phe) diet has been demonstrated to be the most successful treatment in subjects with phenylketonuria (PKU), especially for preventing severe cognitive and neurological damages. However, it still concerns that even if treated in the first months of life with supplements and following a diet, they can show slight scores below people without PKU in neuropsychological assignments. We investigated 20 adults with classical PKU aged 19-48 years (mean age 29 years) and 20 heathy controls matched by age, gender, and years of education. Patients and controls were assessed with an extended neuropsychological battery, as well as psychological aspects and quality of life, also the last Phe level result was obtained. Results showed that the most affected cognitive domains are processing speed, executive functioning, memory, and also theory of mind, but very well-preserved verbal fluency, language, and visuospatial functioning. In quality of life, some significant results were seen specially in anxiety of Phe levels, anxiety of Phe levels during pregnancy, guilt if poor adherence to supplements, and if dietary protein restriction not followed. No significant results were obtained for the psychological variables. In conclusion, it has been shown that a combination of a low Phe diet, supplement intake, and keeping Phe levels in a low range seems appropriate to have the most normal and alike cognitive performance to persons without PKU.

Children with psoriasis and COVID-19: factors associated with an unfavourable COVID-19 course, and the impact of infection on disease progression (Chi-PsoCov registry).

BACKGROUND: The COVID-19 pandemic has raised questions regarding the management of chronic skin diseases, especially in patients on systemic treatments. Data concerning the use of biologics in adults with psoriasis are reassuring, but data specific to children are missing. Moreover, COVID-19 could impact the course of psoriasis in children. OBJECTIVES: The aim of this study was therefore to assess the impact of COVID-19 on the psoriasis of children, and the severity of the infection in relation to systemic treatments. METHODS: We set up an international registry of paediatric psoriasis patients. Children were included if they were under 18 years of age, had a history of psoriasis, or developed it within 1 month of COVID-19 and had COVID-19 with or without symptoms. RESULTS: One hundred and twenty episodes of COVID-19 in 117 children (mean age: 12.4 years) were reported. The main clinical form of psoriasis was plaque type (69.4%). Most children were without systemic treatment (54.2%); 33 (28.3%) were on biologic therapies, and 24 (20%) on non-biologic systemic drugs. COVID-19 was confirmed in 106 children (88.3%) and 3 children had two COVID-19 infections each. COVID-19 was symptomatic for 75 children (62.5%) with a mean duration of 6.5 days, significantly longer for children on non-biologic systemic treatments (P = 0.02) and without systemic treatment (P = 0.006) when compared with children on biologics. The six children who required hospitalization were more frequently under non-biologic systemic treatment when compared with the other children (P = 0.01), and particularly under methotrexate (P = 0.03). After COVID-19, the psoriasis worsened in 17 cases (15.2%). Nine children (8%) developed a psoriasis in the month following COVID-19, mainly a guttate form (P = 0.01). DISCUSSION: Biologics appear to be safe with no increased risk of severe form of COVID-19 in children with psoriasis. COVID-19 was responsible for the development of psoriasis or the worsening of a known psoriasis for some children.

Music therapy and Sanfilippo syndrome: an analysis of psychological and physiological variables of three case studies.

INTRODUCTION: Mucopolysaccharidosis type III (MPS III) or Sanfilippo syndrome is a neurodegenerative disease caused by the accumulation of mucopolysaccharides in the body. As the symptoms are wide ranging, it is a challenge to provide a diagnosis and psychological treatment for affected children. METHOD: The main objective of this study was to describe a form of music therapy treatment applied to three children diagnosed with MPS III. The psychological variables were evaluated by an ad hoc observation recording template, and the physiological variables were measured with a digital meter before and after each session. The perception of the parents was also considered through a semi-structured interview. RESULTS: An improvement in the psychological variables was shown in all cases. Changes in the physiological variables were also noted, although they varied according to each child. The parents report some benefit of music therapy and they share difficulty in assessing the extent of benefits of the music therapy. DISCUSSION: Findings indicate that music therapy can be a useful form of treatment with multiple benefits for children with conditions such as MPS III or similar conditions. However, further research is needed in this area and in the development of specific ways of evaluating music therapy.

Ketogenic diet and cognition in neurological diseases: a systematic review.

CONTEXT: In recent years, the ketogenic diet has gained special relevance as a possible therapeutic alternative to some neurological and chronic diseases. OBJECTIVE: The aim of this systematic review was to answer the following question: Does a ketogenic diet improve cognitive skills in patients with Alzheimer's disease, Parkinson's disease, refractory epilepsy, and type 1 glucose deficiency syndrome? To define the research question, the PICOS criteria were used, following the guidelines of the PRISMA method. DATA SOURCES: Medline/PubMed, Elsevier Science Direct, Dialnet, EBSCOhost, Mediagraphic, Sage Journals, ProQuest, and Wiley Online Library databases were used. DATA EXTRACTION: After applying inclusion and exclusion criteria in accordance with the PRISMA method, a total of 63 entries published between 2004 and 2019 were used. DATA ANALYSIS: The records extracted were analyzed from a qualitative approach, so no statistical analysis was carried out. CONCLUSION: Although scientific literature on the subject is scarce and there has tended to be a lack of scientific rigor, the studies reviewed confirmed the effectiveness of this diet in improving the cognitive symptomatology of the aforementioned diseases.

A Spanish Society joint SECO and SEEDO approach to the Post-operative management of the patients undergoing surgery for obesity.

PURPOSE: Bariatric surgery is the method of choice for the management or treatment of obesity. Bariatric surgery brings about several physiological changes in the body and is associated with set of complications. The aim of this study is to provide guidelines on post bariatric surgery management based on consensus by the Spanish society for Obesity Surgery (Sociedad Española de Cirugía de la Obesidad) (SECO) and the Spanish Society for the Study of Obesity (Sociedad Española para el Estudio de la Obesidad) (SEEDO). METHOD: The boards proposed seven experts from each society. The experts provided the evidence and a grade of recommendation on the selected topics based on systematic reviews/meta-analysis. A list of clinical practical recommendations levels of evidence and grades of these recommendations was derived from the consensus statements from the members of these societies. RESULTS: Seventeen topics related to post-operative management were reviewed after bariatric surgery. The experts came with 47 recommendations and statements. The mean number of persons voting at each statement was 54 (range 36-76). CONCLUSION: In this consensus, we have designed a set of guidelines to be followed while managing patients after bariatric surgery. Expertise and knowledge of the clinicians are required to convey suitable considerations to the post-bariatric patients. There should also be extensive follow-up plans for the bariatric surgery patients.

Integral nutritional approach to the care of cancer patients: results from a Delphi panel.

INTRODUCTION: Malnutrition is a common complication in cancer patients and can negatively affect the outcome of treatments. This study aimed to reach a consensus on nutritional needs and optimize nutritional care in the management of cancer patients at a national level. METHODS: A qualitative, multicenter, two-round Delphi study involving 52 specialists with experience in nutritional support in cancer patients was conducted. RESULTS: Regarding the presence of malnutrition, 57.7% of the participants stated that < 30% of the patients had malnutrition at the time of diagnosis, 40.4% considered that 31-50% had malnutrition during cancer treatment, and 26.9% that > 50% at the end of the treatment. Forty percent of participants believed that the main objective of nutritional treatment was to improve quality of life and 34.6% to improve tolerability and adherence to chemotherapy. The quality nutritional care provided at their centers was rated as medium-low by 67.3%. Enteral and parenteral nutrition was administered to less than 10% and less than 5% of patients in 40.4 and 76.9% of cases, respectively. In relation to nutritional screening at the time of diagnosis, 62.9% of participants considered than screening to assess the risk of malnutrition was performed in < 30% of patients. CONCLUSIONS: There is an important variability in the management of cancer patient nutrition, which is associated with the absence of a national consensus on nutritional support in this field. Given the incidence of nutritional disorders in cancer patients, a specialist in clinical nutrition (regardless of his/her specialty) should be integrated into the strategic cancer plan.

First International Public Health Film Competition 2016-reflections on the development and use of competition judging criteria.

Background: Film competitions can be a helpful method to understand issues of quality in health films. In this paper, we describe the development and use of explicit quality criteria to identify the 'best' films for the first ever international public health film competition. Methods: A film selection committee encompassing a range of stakeholders was compiled. The committee drew up 10 explicit quality criteria to judge films drawing upon other film festival's selection criteria. These criteria were then applied to a broad range of health-related films entered into a film competition to select the 'best' film to screen. Results: Eighty-four films from 20 different countries were submitted to the public health film competition. The originality of the subject covered by the film, the public health importance of the issue and story-telling approach in the film were found to be the most discriminatory criteria to select films. Conclusion: Selection of health films for festivals can be undertaken using explicit quality criteria. There are a number of advantages to such an approach; however, explicit selection involves a large commitment of resources from film festival organizers and there is further research required to test the validity of the quality criteria applied to health-related films.

Iso-Kikuchi Syndrome: Report of 3 Pediatric Cases. / Síndrome de Iso-Kikuchi: 3 casos en la edad pediátrica.

Iso-Kikuchi syndrome, or congenital onychodysplasia of the index finger, is an uncommon condition characterized by total anonychia or dysplasia of the nail of the index finger. It is occasionally accompanied by underlying bone abnormalities and is rarely associated with other conditions. Although various hypotheses have been put forward to explain the pathophysiology of the syndrome, its etiology remains unknown. We report the cases of 3 pediatric patients (2 boys and 1 girl) with nail changes and bone abnormalities consistent with Iso-Kikuchi syndrome. We highlight the importance of recognizing this entity early to avoid the need for additional tests and unnecessary treatment.

Gemcitabine plus sirolimus for relapsed and progressing osteosarcoma patients after standard chemotherapy: a multicenter, single-arm phase II trial of Spanish Group for Research on Sarcoma (GEIS).

BACKGROUND: Patients with relapsed unresectable osteosarcoma represents an unmet need, so active and safe systemic treatments are required. Fas cell surface death receptor and mammalian target of rapamycin pathways are implicated in progressing osteosarcoma, and we had preclinical and clinical experience with a scheme that targets both pathways. Therefore, we designed a phase II trial with gemcitabine plus rapamycin, to determine the efficacy and safety, in this subset of patients. PATIENTS AND METHODS: A multicenter, single-arm phase II trial was sponsored by the Spanish Group for Research on Sarcoma. Osteosarcoma patients, relapsed or progressing after standard chemotherapy and unsuitable for metastasectomy received gemcitabine and rapamycin p.o. 5 mg/day except for the same day of gemcitabine administration, and the day before. The main end point was 4-month progression-free survival rate (PFSR), with the assumption that rates higher than 40% would be considered as an active regimen. Translational research aimed to correlate biomarkers with the clinical outcome. RESULTS: Thirty-five patients were enrolled and received at least one cycle. PFSR at 4 months was 44%, and after central radiologic assessment, 2 partial responses and 14 stabilizations (48.5%) were reported from 33 assessable patients. The most frequent grade 3-4 adverse events were: neutropenia (37%), thrombocytopenia (20%), anemia (23%), and fatigue (15%); however, only three patients had febrile neutropenia. Positive protein expression of RRM1 significantly correlated with worse PFS and overall survival, while positivity of P-ERK1/2 was correlated with significant better overall survival. CONCLUSION: Gemcitabine plus sirolimus exhibits satisfactory antitumor activity and safety in this osteosarcoma population, exceeding the prespecified 40% of 4-month PFSR. The significant correlation of biomarkers with clinical outcome encourages further prospective investigation.

Post-implant Analysis of Epidemiologic and Eating Behavior Data Related to Weight Loss Effectiveness in Obese Patients Treated with Gastric Electrical Stimulation.

OBJECTIVE: To determine possible preoperative predictors for obtaining clinically meaningful weight loss with gastric electrical stimulation (GES) using the "Three-Factor Eating Questionnaire" (TFEQ) as well as epidemiological data. METHODS: Ninety-seven obese participants in a prospective multicenter randomized study conducted in nine European centers were implanted laparoscopically with the abiliti® closed-loop GES system (CLGES). Five clinical variables and three preoperative TFEQ factor scores (F1-cognitive-restraint, F2-disinhibition, and F3-hunger) were analyzed in order to determine predictors of weight loss success defined as excess weight loss (EWL) > 30% and failure defined as EWL < 20% at 12 months post-surgery. RESULTS: The mean 12-month %EWL with CLGES was 35.1 ± 19.7%, with a success rate of 52% and a failure rate of 19%. Significant predictors of success were body mass index (BMI) < 40 kg/m2 and age ≥ 50 years, increasing probability of success by 22 and 29%, respectively. A low F1-cognitive-restraint score was a significant predictor of failure (p = 0.004). The best predictive model for success included F1-cognitive-restraint, F2-disinhibition, BMI < 40, and age ≥ 50 (p = 0.002). CONCLUSION: This retrospective analysis has shown that age, preoperative BMI, and F1-cognitive-restraint and F2-disinhibition scores from a preoperatively administered TFEQ are predictive of weight loss outcomes with CLGES and may be used for patient selection.

Short-term safety, tolerability and efficacy of a very low-calorie-ketogenic diet interventional weight loss program versus hypocaloric diet in patients with type 2 diabetes mellitus.

UNLABELLED: Brackground:The safety and tolerability of very low-calorie-ketogenic (VLCK) diets are a current concern in the treatment of obese type 2 diabetes mellitus (T2DM) patients. OBJECTIVE: Evaluating the short-term safety and tolerability of a VLCK diet (<50 g of carbohydrate daily) in an interventional weight loss program including lifestyle and behavioral modification support (Diaprokal Method) in subjects with T2DM. METHODS: Eighty-nine men and women, aged between 30 and 65 years, with T2DM and body mass index between 30 and 35 kg m(-)(2) participated in this prospective, open-label, multi-centric randomized clinical trial with a duration of 4 months. Forty-five subjects were randomly assigned to the interventional weight loss (VLCK diet), and 44 to the standard low-calorie diet. RESULTS: No significant differences in the laboratory safety parameters were found between the two study groups. Changes in the urine albumin-to-creatinine ratio in VLCK diet were not significant and were comparable to control group. Creatinine and blood urea nitrogen did not change significantly relative to baseline nor between groups. Weight loss and reduction in waist circumference in the VLCK diet group were significantly larger than in control subjects (both P<0.001). The decline in HbA1c and glycemic control was larger in the VLCK diet group (P<0.05). No serious adverse events were reported and mild AE in the VLCK diet group declined at last follow-up. CONCLUSIONS: The interventional weight loss program based on a VLCK diet is most effective in reducing body weight and improvement of glycemic control than a standard hypocaloric diet with safety and good tolerance for T2DM patients.

Impact of a training course on the quality of chest radiography to diagnose pulmonary tuberculosis.

SETTING: Socio-economically underprivileged urban areas in the Philippines. OBJECTIVE: To assess the performance of radiological technicians (RTs) 3 years after their participation in a training course to improve the quality of chest X-ray (CXR) and to test a monitoring visit after the course. DESIGN: A cross-sectional and observational study including on-site monitoring of X-ray facilities in Manila and Quezon City and assessment of CXR films taken by 23 RTs who previously attended a training course in 2009 or 2010. The sum of the assessment scores for each of six assessment factors at four points, i.e., before and after the training course that had been previously analysed, and before and after the monitoring visits that were currently analysed, were compared. RESULTS: Two assessment sum scores, identification mark or patient positioning, did not show significant differences. However, assessment of density, contrast, sharpness and artefact significantly improved after the training course, and before and after the monitoring visit, compared with before the training. There were no significant differences in any of the assessment factors before and after the monitoring visits. CONCLUSION: The training course appears to have had a long-term effect on maintaining CXR quality. The post-training monitoring visit did not significantly improve CXR quality.

Contexte : Zones urbaines de bas niveau socio-économique aux Philippines.Objectif : Evaluer la performance des manipulateurs radio (RT) dans les 3 années suivant leur participation à un cours de formation destiné à améliorer la qualité des radiographies pulmonaires (CXR) ainsi que l'effet d'une visite de suivi après le cours.Schéma : Etude transversale et d'observation incluant le suivi sur place des structures de radiographie à Manille et Quezon et l'évaluation des clichés de CXR pris par 23 RT qui avaient assisté au cours de formation en 2009 ou 2010. Les sommes des scores d'évaluation de chacun des six facteurs d'évaluation à quatre moments, c'est-à-dire avant et après le cours de formation qui avaient été évalués précédemment et avant et après les visites de suivi qui étaient en cours d'analyse, ont été comparées.Résultats : Deux sommes de scores d'évaluation­identification du cliché ou positionnement du patient­n'ont pas mis en évidence de différence significative. Cependant, en ce qui concerne la densité, le contraste, la définition et les artefacts, une amélioration significative a été constatée après le cours de formation et avant et après la visite de suivi, par comparaison avec les résultats préalables à la formation. Par contre, il n'y a eu de différence significative dans aucun des facteurs d'évaluation avant et après les visites de suivi.Conclusion : Le cours de formation a démontré un effet à long terme en termes de maintien de la qualité des RP. Par contre, la visite de suivi après la formation n'a pas significativement amélioré la qualité des RP.

Marco de referencia: Zonas urbanas en situación socioeconómica desfavorable en las Filipinas.Objetivo: Evaluar el desempeño de los auxiliares técnicos de radiología (RT) 3 años después de haber participado en un curso de capacitación destinado a mejorar la calidad de la radiografía de tórax (CXR) y la utilidad de una visita de supervisión después del curso.Métodos: Se llevó a cabo un estudio transversal y de observación, en el cual se realizó una supervisión directa de las instalaciones de radiología en Manila y Ciudad Quezón y se evaluaron las CXR realizadas por 23 auxiliares RT que habían atendido a un curso de capacitación en el 2009 o el 2010. Se calificaron seis criterios de calidad de las CXR y la suma de las puntuaciones de cada criterio se categorizó en cuatro niveles; se compararon las sumatorias de las puntuaciones en cada momento de evaluación antes y después de la capacitación y antes y después de las visitas de supervisión realizadas durante el estudio.Resultados: Las sumatorias de las puntuaciones de dos criterios­la marca de identificación y el posicionamiento del paciente­no exhibieron diferencias significativas en los diferentes momentos de evaluación. Sin embargo, las puntuaciones sobre la densidad, el contraste, la nitidez y la presencia de artefactos revelaron una mejoría significativa después de la capacitación y también antes y después de la visita de supervisión, comparadas con las calificaciones obtenidas antes del curso de capacitación. No se observaron diferencias significativas en los criterios de calidad evaluados antes y después de las visitas de supervisión.Conclusión: El curso de capacitación ofrece un efecto a largo plazo sobre el mantenimiento de la calidad de las CXR. Las visitas de supervisión posteriores al entrenamiento no tuvieron una repercusión importante sobre la calidad.

Enzymatic synthesis of triacylglycerols of docosahexaenoic acid: Transesterification of its ethyl esters with glycerol.

The synthesis of docosahexaenoyl triacylglycerides at low temperature (e.g., 50°C) using biocatalysts of 6 commercial lipases adsorbed on hydrophobic supports was studied. In general, the triacylglyceride yields were very low with the exceptions of those produced with the enzymes from Candida antarctica fraction B, CALB (82%), and those produced with the enzyme from Pseudomonas fluorescens, PFL (57%). The reactions were performed under vacuum to remove the released ethanol. The yields varied widely when different derivatives of CALB were used, and they were higher when CALB adsorbed on hydrophobic supports was used (82%). One interesting by-product (18% of sn-2 monoacylglyceride of DHA) remained at the end of the synthetic process. CALB adsorbed on Sepabeads exhibited better activity and stability than did the commercial derivative Novozym 435. The best CALB biocatalyst preserved 90% of the activity after 30days under the reaction conditions.

Effect of bariatric surgery on microvascular dysfunction associated to metabolic syndrome: a 12-month prospective study.

OBJECTIVE: To prospectively evaluate the effect of weight loss after bariatric surgery on microvascular function in morbidly obese patients with and without metabolic syndrome (MetS). METHODS: A cohort of morbidly obese patients with and without MetS was studied before surgery and after 12 months of surgery. Healthy lean controls were also examined. Microvascular function was assessed by postocclusive reactive hyperemia (PORH) at forearm skin evaluated by laser Doppler flowmetry (LDF). Cutaneous vascular conductance (CVC) was calculated from laser-Doppler skin blood flow and blood pressure. Regression analysis was performed to assess the contribution of different clinical, metabolic and biochemical parameters to microvascular function. RESULTS: Before surgery, 62 obese patients, 39 with MetS and 23 without MetS, and 30 lean control subjects were analyzed. The absolute area under the hyperemic curve (AUC(H)) CVC of PORH was significantly decreased in obese patients compared with lean control subjects. One year after surgery, AUC(H) CVC significantly increased in patients free of MetS, including patients that had MetS before surgery. In contrast, AUC(H) CVC did not significantly change in patients in whom MetS persisted after surgery. Stepwise multivariate regression analysis showed that only changes in HDL cholesterol (HDL-C) and oxidized LDL (oxLDL) independently predicted improvement of AUC(H) after surgery. These two variables together accounted for 40.9% of the variability of change in AUC(H) CVC after surgery. CONCLUSIONS: Bariatric surgery could significantly improve microvascular dysfunction in obese patients, but only in patients free of MetS after surgery. Improvement of microvascular dysfunction is strictly associated to postoperative increase in HDL-C levels and decrease in oxLDL levels.

Outcome of acute renal injury in diabetic mice with experimental endotoxemia: role of hypoxia-inducible factor-1 α.

The role of diabetic nephropathy in the outcome of acute renal injury (AKI) is not well defined. Herein we evaluate the outcome of lipopolysaccharide- (LPS-) induced AKI in streptozotocin-induced diabetes, as well as the potential role of Hypoxia Inducible Factor (HIF-1 α ) in this condition. Although 6 h after LPS injection all mice developed a decrease in renal function, proteinuric diabetic mice showed a better recovery of this parameter throughout the study (72 h). Both HIF-1 α and vascular endothelium growth factor (VEGF) were found to be upregulated in diabetic mice. After LPS injection, all animals showed an upregulation of these factors, although it was higher in the diabetic group. Glycated albumin (GA) was found to upregulate HIF-1 α in HK-2 cells, which resulted in increased production of VEGF. Interestingly, LPS cooperated with GA to induce HIF-1 α upregulation. In conclusion, diabetic mice display a better recovery of AKI after experimental endotoxemia. Moreover, these animals showed an increased expression of both HIF-1 α and VEGF that was reproduced by incubating renal cells with GA. Since VEGF is considered a survival factor for tubular cells, our findings suggest that diabetes displays HIF-1 α upregulation that might function as a "precondition state" offering protection from endotoxic AKI.
