Mustard seed major allergen Sin a1 activates intestinal epithelial cells and also dendritic cells that drive type 2 immune responses.

Mustard seeds belong to the food category of mandatory labelling due to the severe reactions they can trigger in allergic patients. However, the mechanisms underlying allergic sensitization to mustard seeds are poorly understood. The aim of this work is to study type 2 immune activation induced by the mustard seed major allergen Sin a1 via the intestinal mucosa, employing an in vitro model mimicking allergen exposure via the intestinal epithelial cells (IECs). Sin a1 was isolated from the total protein extract and exposed to IEC, monocyte derived dendritic cells (DCs) or IEC/DC co-cultures. A system of consecutive co-cultures was employed to study the generic capacity of Sin a1 to induce type 2 activation leading to sensitization: IEC/DC, DC/T-cell, T/B-cell and stem cell derived mast cells (MCs) derived from healthy donors. Immune profiles were determined by ELISA and flow cytometry. Sin a1 activated IEC and induced type-2 cytokine secretion in IEC/DC co-culture or DC alone (IL-15, IL-25 and TSLP), and primed DC induced type 2 T-cell skewing. IgG secretion in the T-cell/B-cell phase was enhanced in the presence of Sin a1 in the first stages of the co-culture. Anti-IgE did not induce degranulation but promoted IL-13 and IL-4 release by MC primed with the supernatant from B-cells co-cultured with Sin a1-IEC/DC or -DC primed T-cells. Sin a1 enhanced the release of type-2 inflammatory mediators by epithelial and dendritic cells; the latter instructed generic type-2 responses in T-cells that resulted in B-cell activation, and finally MC activation upon anti-IgE exposure. This indicates that via activation of IEC and/or DC, mustard seed allergen Sin a1 is capable of driving type 2 immunity which may lead to allergic sensitization.

[Translated article] Retrospective study of home antibiotic infusion therapy using elastomeric infusion pumps.

OBJECTIVES: To describe the experience of home antibiotic infusion therapy using elastomeric infusion pumps, administered to patients admitted to the Home Hospitalisation Unit of a tertiary hospital for 3 years and to analyse clinical evolution and mortality. METHOD: Retrospective observational study. The medical history of the patients included in the study was reviewed. Information was obtained on personal history, antimicrobial therapy received, and clinical evolution. Statistical analysis was performed using SPSS® 19 software. RESULTS: 81 patients were included, 61.7% men, with a mean age of 73.5±17.5 years. The most frequent comorbidities were diabetes mellitus (30.9%) and chronic kidney disease (28.4%). Patients received a mean of 11.9±8.5 days of antibiotic treatment in an elastomeric infusion pump. The main focus of infection was respiratory (27.2%), followed by bacteremia (16%) and skin and soft tissue infections (12.3%). Of the infections, 65.4% were monomicrobial, with Pseudomonas aeruginosa being the main microorganism involved (39.6%). The most commonly used antimicrobial was piperacillin/tazobactam (33.3%). The clinical course was good in 85.2% of the patients, but the mortality rate in the 30 days following the end of treatment was 24.7%. In the univariate analysis, a history of neoplasia in the last 5 years (p=.01) and having received fewer days of antibiotic therapy prior to the start of outpatient antimicrobial therapy in infusion pump (p=.04) were associated with worse clinical outcome. Age over 80 years was associated with better outcome (p=.03). The diagnosis of heart failure was associated with higher mortality (p=.026) and patients from surgical services, with lower mortality (p=.047). In the multivariate analysis, the presence of neoplasia was associated with unfavourable evolution (p=.012) and heart failure with higher mortality (p=.027). CONCLUSIONS: Outpatient antimicrobial therapy in elastomeric infusion pumps is an alternative in patients requiring prolonged intravenous treatment, and age is not a conditioning factor for inclusion in these programs. However, the presence of certain comorbidities can negatively affect the clinical course and mortality of patients.

Effectiveness of web-based personalised feedback interventions for reducing alcohol consumption among university students: A systematic review and meta-analysis.

ISSUES: Meta-analysis was conducted to examine standalone web-based personalised feedback interventions (PFI) delivered in non-structured settings for reducing university students' alcohol consumption. Subgroup analyses by gender-focus, type-of-content and accessibility were conducted. Characteristics of the sample, the intervention and study quality were examined as moderators. APPROACH: Ten databases were searched from 2000 to 2023. Eligible articles involved only randomised controlled trials. Random-effects meta-analysis was conducted to calculate the effect size on weekly alcohol consumption comparing web-PFIs and non-active controls. Meta-regressions were applied to explore effect moderators. KEY FINDINGS: Thirty-one studies were included in the narrative synthesis, 25 of which were meta-analysed. Results found significant effect size differences on weekly alcohol consumption in favour of the intervention group in the short- (SMD = 0.11, 95% confidence interval [CI] 0.06, 0.15) and long-term period (SMD = 0.09, 95% CI 0.02, 0.15). Subgroup analyses identified that interventions which were gender-specific, multicomponent and had unlimited access had higher and significant effect sizes, although they were very similar with respect to comparative groups. Moderator analyses showed that times feedback was accessed significantly contributed to the effectiveness of the intervention. Effects diminished over time, although they remained significant. IMPLICATIONS: The meta-analysis evidences the effectiveness of web-PFI for addressing university students' alcohol use, decreasing by 1.65 and 1.54 drinks consumed per week in the short- and long-term, respectively. CONCLUSIONS: The results offer empirical evidence that supports the significant, although small, effect of web-PFI delivered remotely in universities. Future research should focus on increasing their impact by introducing booster sessions and content components based on students' preferences.

Power Doppler signal at the enthesis and bone erosions are the most discriminative OMERACT ultrasound lesions for SpA: results from the DEUS (Defining Enthesitis on Ultrasound in Spondyloarthritis) multicentre study.

OBJECTIVES: To assess, in spondyloarthritis (SpA), the discriminative value of the Outcome Measures in Rheumatology (OMERACT) ultrasound lesions of enthesitis and their associations with clinical features in this population. METHODS: In this multicentre study involving 20 rheumatology centres, clinical and ultrasound examinations of the lower limb large entheses were performed in 413 patients with SpA (axial SpA and psoriatic arthritis) and 282 disease controls (osteoarthritis and fibromyalgia). 'Active enthesitis' was defined as (1) power Doppler (PD) at the enthesis grade ≥1 plus entheseal thickening and/or hypoechoic areas, or (2) PD grade >1 (independent of the presence of entheseal thickening and/or hypoechoic areas). RESULTS: In the univariate analysis, all OMERACT lesions except enthesophytes/calcifications showed a significant association with SpA. PD (OR=8.77, 95% CI 4.40 to 19.20, p<0.001) and bone erosions (OR=4.75, 95% CI 2.43 to 10.10, p<0.001) retained this association in the multivariate analysis. Among the lower limb entheses, only the Achilles tendon was significantly associated with SpA (OR=1.93, 95% CI 1.30 to 2.88, p<0.001) in the multivariate analyses. Active enthesitis showed a significant association with SpA (OR=9.20, 95% CI 4.21 to 23.20, p<0.001), and unlike the individual OMERACT ultrasound lesions it was consistently associated with most clinical measures of SpA disease activity and severity in the regression analyses. CONCLUSIONS: This large multicentre study assessed the value of different ultrasound findings of enthesitis in SpA, identifying the most discriminative ultrasound lesions and entheseal sites for SpA. Ultrasound could differentiate between SpA-related enthesitis and other forms of entheseal pathology (ie, mechanical enthesitis), thus improving the assessment of entheseal involvement in SpA.

RUNX1 C-terminal mutations impair blood cell differentiation by perturbing specific enhancer-promoter networks.

ABSTRACT: The transcription factor RUNX1 is a master regulator of hematopoiesis and is frequently mutated in myeloid malignancies. Mutations in its runt homology domain (RHD) frequently disrupt DNA binding and result in loss of RUNX1 function. However, it is not clearly understood how other RUNX1 mutations contribute to disease development. Here, we characterized RUNX1 mutations outside of the RHD. Our analysis of the patient data sets revealed that mutations within the C-terminus frequently occur in hematopoietic disorders. Remarkably, most of these mutations were nonsense or frameshift mutations and were predicted to be exempt from nonsense-mediated messenger RNA decay. Therefore, this class of mutation is projected to produce DNA-binding proteins that contribute to the pathogenesis in a distinct manner. To model this, we introduced the RUNX1R320∗ mutation into the endogenous gene locus and demonstrated the production of RUNX1R320∗ protein. Expression of RUNX1R320∗ resulted in the disruption of RUNX1 regulated processes such as megakaryocytic differentiation, through a transcriptional signature different from RUNX1 depletion. To understand the underlying mechanisms, we used Global RNA Interactions with DNA by deep sequencing (GRID-seq) to examine enhancer-promoter connections. We identified widespread alterations in the enhancer-promoter networks within RUNX1 mutant cells. Additionally, we uncovered enrichment of RUNX1R320∗ and FOXK2 binding at the MYC super enhancer locus, significantly upregulating MYC transcription and signaling pathways. Together, our study demonstrated that most RUNX1 mutations outside the DNA-binding domain are not subject to nonsense-mediated decay, producing protein products that act in concert with additional cofactors to dysregulate hematopoiesis through mechanisms distinct from those induced by RUNX1 depletion.

Family-Oriented Therapeutic Conversations: A Systematic Scoping Review.

There is increasing evidence that highlights the benefits of Family-oriented Therapeutic Conversations (FAM-TC) for the patient and the family; however, studies show variability regarding the content and the way these interventions are offered. This may hamper its further development in clinical practice. This review systematically maps the available literature on nurse-led FAM-TC and offers a solid synthesis of the characteristic, effectiveness, and feasibility of these interventions. A systematic search in PubMed, CINAHL, Cochrane, Web of Science, PsycINFO, Trip (Turning Research Into Practice), BASE (Bielefeld Academic Search Engine), OATD (Open Access Theses and Dissertations), and ProQuest databases identified 37 studies. The interventions varied in interventionist nurses' profile, the intervention content, or the duration of the sessions offered. Most of the interventions showed beneficial effects on perceived family support and family functioning. This review offers suggestions for future studies, such as the inclusion of specific theoretical frameworks for intervention design, targeting both the patient and the family and offered by nurses with family nursing competency.

Differences in children's exposure to television advertising of unhealthy foods and beverages in Spain by socio-economic level.

BACKGROUND: The influence of food advertising on food preferences and consumption could also contribute to the socio-economic inequalities among Spanish children in terms of eating habits and childhood obesity. Although the main food advertising channel targeted at children in Spain is television, available studies estimate exposure indirectly by combining content data with audience data. The aim of this study was therefore to describe the frequency of exposure to television advertising of unhealthy foods and drinks, measured directly, among Spanish children and adolescents, and analyse its socio-economic inequalities. METHODS: Observational study of television advertising impacts in a sample of 1590 children aged 4 to 16 years drawn from a consumer panel representative of the Spanish population in this age group, over the course of a full week of broadcasting in February 2022. The sample was obtained through stratified random sampling by Autonomous Region, with quotas being set by reference to socio-demographic variables. Exposure was measured with an audiometer, and the nutrient content of the food and drink advertised was analysed using the nutrient profile of the WHO Regional Office for Europe. We used the Chi-squared test to analyse possible differences in advertising coverage by socio-economic level. RESULTS: The participants saw a weekly mean of 82.4 food and drink commercials, 67.4 of which were for unhealthy products (81.8%), mostly outside the child-protection time slot. On average, low-social class participants received 94.4% more impacts from unhealthy food and drink advertising than did high-class participants (99.9 vs. 51.4 respectively). The mean advertising coverage of unhealthy foods and drinks was 71.6% higher in low-class than in high-class participants (10.9% vs. 18.7%; p = 0.01). CONCLUSION: Spanish children and adolescents received an average of 10 impacts per day from television spots for unhealthy foods and drinks. The exposure of low-class children is double that of high-class children, a finding compatible with the high prevalence of childhood obesity in Spain and the related socio-economic inequalities. To protect Spanish minors from the harmful effects of food advertising and reduce the related social health inequalities would require the implementation of a 24:00 watershed for unhealthy food advertising on television.

[Trends in the characteristics of patients treated with nutritional supplements in the Northern Area of Gran Canaria in the period 2016 -2021]. / Tendencias en las características de los pacientes tratados con suplementos nutricionales en el Área Norte de Gran Canaria en el periodo 2016 -2021.

AIM: assess the prescription of oral nutritional supplements (ONS) in the Northern Area of Gran Canaria in the period 2016-2021. MATERIALS AND METHODS: based on electronic prescription data, the first ONS prescription during 2016-2021 was analyzed considering age, gender, nutritional requirements (NR), body mass index (BMI), percentage of weight loss (%WL), albumin and number of prescribed ONS per patient. RESULTS: 10,595 prescriptions were identified corresponding to 6661 patients with the following characteristics: 46.3 % men, mean age 72.84 ± 15.93 years, BMI 20.60 ± 3.98 kg/m2, %WL 11.89 ± 8.32 %; albumin 3.08 ± 0.63 g/dl. The most frequent etiologies of DRE were: neoplasms 42.6 %; degenerative processes of the CNS 28.9 %; stroke 3.9 %; short intestine 6.9 %, and inflammatory bowel disease (IBD) 5.5 %. The percentages of NR covered by the prescribed ONS were: 100 % in 8.9 % of cases, 50 % in 36.9 %, and 25 % in 54.2 %; 40.4 % of patients received 1 unit of ONS daily, 36.3 % took 2 units of ONS, and 23 % received > 3 units of ONS per day. Greater NR were associated with a greater number of ONS (p < 0.001), but 40.8 % of patients who needed to cover > 50 % of NR received only one unit of ONS. CONCLUSION: a significant percentage of patients with DRM do not receive a number of ONS according to their NR.

Oncological outcomes of intraperitoneal chemotherapy in advanced ovarian cancer: BRCA mutation role.

INTRODUCTION: The knowledge of BRCA status offers a chance to evaluate the role of the intraperitoneal route in patients selected by biomolecular profiles after primary cytoreduction surgery in advanced ovarian cancer. MATERIALS AND METHODS: We performed a retrospective, multicenter study to assess oncological outcomes depending on adjuvant treatment (intraperitoneal [IP] vs intravenous [IV]) and BRCA status (BRCA1/2 mutated vs. BRCA wild type [WT]). The primary endpoint was to determine progression-free survival. The secondary objectives were overall survival and toxicity. RESULTS: A total of 288 women from eight centers were included: 177 in the IP arm and 111 in the IV arm, grouped into four arms according to BRCA1/2 status. Significantly better PFS was observed in BRCA1/2-mutated patients with IP chemotherapy (HR: 0.35; 95% CI, 0.16-0.75, p = 0.007), which was not present in BRCA1/2-mutated patients with IV chemotherapy (HR: 0.65; 95% CI, 0.37-1.12, p = 0.14). Significantly better OS was also observed in IP chemotherapy (HR: 0.17; 95% CI, 0.06-043, p < 0.0001), but was not present in IV chemotherapy in relation with BRCA mutation (HR: 0.52; 95% CI, 0.22-1.27, p = 0.15). For BRCA WT patients, worse survival was observed regardless of the adjuvant route used. The IP route was more toxic compared to the IV route, but toxicity was equivalent at the long-term follow-up. CONCLUSION: This retrospective study suggests that BRCA status can help to offer an individualized, systematic treatment after optimal primary surgery for advanced ovarian cancer, but is limited by the small sample size. Prospective trials are essential to confirm these results.

Polymyalgia Rheumatica Post-SARS-CoV-2 Infection.

There is growing evidence that infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to dysregulation of the immune system and, consequently, the development of autoimmune phenomena. Here, we describe the case of a 75-year-old woman with rheumatic manifestations characterized by intense musculoskeletal pain and stiffness in the neck and shoulders, with sudden onset and with the inability to raise her arms. The patient was admitted with severe pain located in the neck and shoulders. Previously, she had oropharyngeal pain, severe fatigue, and fever; a real-time polymerase chain reaction test for COVID-19 was positive. Two weeks later, the patient presented localized musculoskeletal pain in the neck and shoulders. Relevant laboratory results included an erythrocyte sedimentation rate of 46 mm/hr and a negative rheumatoid factor test; ultrasound findings with bilateral subacromial-subdeltoid bursitis were observed. A diagnosis of polymyalgia rheumatica (PMR) was initially made according to the EULAR/ACR provisional classification criteria for PMR; however, due to C-reactive protein negativity, the diagnosis was established based on symptoms. Management was with prednisone at the dose of 25 mg/day for 4 weeks and progressive reduction until prednisone suspension. The patient showed complete recovery at 6 months of follow-up. In this case, COVID-19 was implicated in the development of autoimmune and inflammatory rheumatic manifestations. PMR is a rare rheumatic condition that should be included in the wide range of rheumatologic manifestations expressed post-SARS-CoV-2 infection.

Russell body duodenitis: a rare condition.

Russell bodies are accumulations of immunoglobulins within hyperstimulated plasma cells of the intestinal mucosa associated with chronic inflammation of benign progression, but may be confused with lymphoplasmacytic lymphoma, MALT lymphoma, multiple myeloma, or "signet-ring" cells, among others. There are few cases of gastric involvement, but duodenal involvement is even rarer with less than 10 published cases. Endoscopic examination with quality biopsies and anatomopathologic analysis with immunohistochemistry are essential to make an adequate differential diagnosis with other more severe processes. In any case, the treatment is that of the underlying disease.

Retrospective study of home antibiotic infusion therapy in elastomeric infusion pumps. / Estudio retrospectivo de la terapia de infusión de antibióticos domiciliaria en bombas de infusión elastoméricas.

OBJECTIVES: To describe the experience of home antibiotic infusion therapy using elastomeric infusion pumps, administered to patients admitted to the Home Hospitalization Unit of a tertiary hospital for three years and to analyse clinical evolution and mortality. METHOD: Retrospective observational study. The medical history of the patients included in the study was reviewed. Information was obtained on personal history, antimicrobial therapy received and clinical evolution. Statistical analysis was performed using SPSS® 19 software. RESULTS: Eighty-one patients were included, 61.7% men, with a mean age of 73.5 ± 17.5 years. The most frequent comorbidities were diabetes mellitus (30.9%) and chronic kidney disease (28.4%). Patients received a mean of 11.9 ± 8.5 days of antibiotic treatment in an elastomeric infusion pump. The main focus of infection was respiratory (27.2%), followed by bacteremia (16%) and skin and soft tissue infections (12.3%). Of the infections, 65.4% were monomicrobial, with Pseudomonas aeruginosa being the main microorganism involved (39.6%). The most commonly used antimicrobial was piperacillin/tazobactam (33.3%). The clinical course was good in 85.2% of the patients, but the mortality rate in the 30 days following the end of treatment was 24.7%. In the univariate analysis, a history of neoplasia in the last 5 years (p = 0.01) and having received fewer days of antibiotic therapy prior to the start of outpatient antimicrobial therapy in infusion pump (p = 0.04) were associated with worse clinical outcome. Age over 80 years was associated with better outcome (p = 0.03). The diagnosis of heart failure was associated with higher mortality (p = 0.026) and patients from surgical services, with lower mortality (p = 0.047). In the multivariate analysis, the presence of neoplasia was associated with unfavorable evolution (p = 0.012) and heart failure with higher mortality (p = 0.027). CONCLUSIONS: Outpatient antimicrobial therapy in elastomeric infusion pumps is an alternative in patients requiring prolonged intravenous treatment, and age is not a conditioning factor for inclusion in these programs. However, the presence of certain comorbidities can negatively affect the clinical course and mortality of patients.

Vomeronasal organ volume increases with body size and is dissociated with the loss of a visual signal in Sceloporus lizards.

Many organisms communicate using signals in different sensory modalities (multicomponent or multimodal). When one signal or component is lost over evolutionary time, it may be indicative of changes in other characteristics of the signalling system, including the sensory organs used to perceive and process signals. Sceloporus lizards predominantly use chemical and visual signals to communicate, yet some species have lost the ancestral ventral colour patch used in male-male agonistic interactions and exhibit increased chemosensory behaviour. Here, we asked whether evolutionary loss of this sexual signal is associated with larger vomeronasal organ (VNO) volumes (an organ that detects chemical scents) compared with species that have retained the colour patch. We measured VNO coronal section areas of 7-8 adult males from each of 11 Sceloporus species (4 that lost and 7 that retained the colour patch), estimated sensory and total epithelium volume, and compared volumes using phylogenetic analysis of covariance, controlling for body size. Contrary to expectations, we found that species retaining the ventral patch had similar relative VNO volumes as did species that had lost the ancestral patch, and that body size explains VNO epithelium volume. Visual signal loss may be sufficiently compensated for by increased chemosensory behaviour, and the allometric pattern may indicate sensory system trade-offs for large-bodied species.

The fluorescent ligand bTVBT2 reveals increased p-tau uptake by retinal microglia in Alzheimer's disease patients and AppNL-F/NL-F mice.

BACKGROUND: Amyloid beta (Aß) deposits and hyperphosphorylated tau (p-tau) accumulation have been identified in the retina of Alzheimer's disease (AD) patients and transgenic AD mice. Previous studies have shown that retinal microglia engulf Aß, but this property decreases in AD patients. Whether retinal microglia also take up p-tau and if this event is affected in AD is yet not described. In the current study, we use the p-tau-specific thiophene-based ligand bTVBT2 to investigate the relationship between disease progression and p-tau uptake by microglia in the retina of AD patients and AppNL-F/NL-F knock-in mice, an AD mouse model known to demonstrate extracellular Aß plaques and dystrophic neurites in the brain from 6 months of age. METHODS: Evaluation of bTVBT2 specificity and its presence within microglia was assessed by immunofluorescent staining of hippocampal sections and flat-mount retina samples from non-demented controls, AD patients, 3-, 9-, and 12-month-old AppNL-F/NL-F knock-in mice and 12- and 18-month-old wild type (WT) mice. We used ImageJ to analyze the amount of bTVBT2 inside Iba1-positive microglia. Co-localization between the ligand and p-tau variant Ser396/Ser404 (PHF-1), Aß, phosphorylated TAR DNA binding protein 43 (pTDP-43), and islet amyloid polypeptide (IAPP) in the brain and retina was analyzed using confocal imaging. RESULTS: Confocal imaging analysis showed that bTVBT2 binds to PHF-1- and AT8-positive aggregates inside retinal microglia, and not to Aß, pTDP-43, or IAPP. The density of bTVBT2-positive microglia was higher in cases with a high Aß load compared to those with a low Aß load. This density correlated with the neurofibrillary tangle load in the brain, but not with retinal levels of high molecular weight (aggregated) Aß40 or Aß42. Analysis of AppNL-F/NL-F knock-in mouse retina further showed that 50% of microglia in 3-month-old AppNL-F/NL-F knock-in mice contained bTVBT2. The percentage significantly increased in 9- and 12-month-old mice. CONCLUSION: Our study suggests that the microglial capability to uptake p-tau in the retina persists and intensifies with AD progression. These results also highlight bTVBT2 as a ligand of interest in future monitoring of retinal AD pathology.

Non-human Clostridioides difficile Reservoirs and Sources: Animals, Food, Environment.

Clostridioides difficile is ubiquitous and is found in humans, animals and in variety of environments. The substantial overlap of ribotypes between all three main reservoirs suggests the extensive transmissions. Here we give the overview of European studies investigating farm, companion and wild animals, food and environments including water, soil, sediment, wastewater treatment plants, biogas plants, air, and households. Studies in Europe are more numerous especially in last couple of years, but are still fragmented in terms of countries, animal species, or type of environment covered. Soil seem to be the habitat of divergent unusual lineages of C. difficile. But the most important aspect of animals and environment is their role in C. difficile transmissions and their potential as a source for human infection is discussed.

Low prevalence of subclinical synovitis in patients with juvenile idiopathic arthritis (JIA) in long-term clinical remission on medication.

Subclinical synovitis is highly prevalent in patients with JIA in clinical remission (CR) with a short duration. The objective was to evaluate its prevalence by ultrasound (US) in patients with JIA in long CR during a one-year follow-up. In this prospective and longitudinal study, we included 76 patients with JIA according to ILAR with CR by the Wallace modified criteria and JADAS27 and compared them with 22 patients with active disease. Clinical and demographic characteristics were recorded. US evaluation was by 10-joint count. Differences in US evaluations were analyzed by the Mann-Whitney U test. There were no differences among the two group with regard to disease duration at enrollment, and age (p = 0.540 and p = 0.080, respectively), but JADAS 27, CHAQ, and acute phase reactants were significantly higher (p < 0.001) in the clinically active group. The prevalence of subclinical synovitis at baseline and the end of the study in the CR group was 18.4% and 11.8%, respectively, while it was 100% and 40.9% in the active disease group. Subclinical synovitis at baseline was significantly more prevalent in the clinically active group (elbow, p = 0.01; wrist, p = 0.001; MCP 2, p = 0.001; knee, p = 0.001 and ankle p = 0.001; and PD only in the ankle, p = 0.002). The concordance of inter-reader reliability in all evaluated joints was excellent (p = 0.001). Although the prevalence of subclinical synovitis is low in patients with JIA with long-term clinical remission on medication, a percentage of patients continue to have subclinical involvement that could predict the risk of relapse and structural damage. Key Points • Subclinical synovitis is less prevalent in JIA in long-term clinical remission compared to patients in short-term remission. • The persistence of imaging signs of inflammation in a significant percentage of patients may indicate the need for ongoing medication.

Accuracy of estimating self and other body size among adolescent girls with anorexia nervosa.

This study aimed to analyze body size estimates of others by patients with anorexia nervosa (AN) and to identify any differences with the perception of their own body size. Adolescent females (age, 13-17 years) were enrolled into AN (n = 30) and control(n = 23) groups. The Subjective Body Dimensions Apparatus (SBDA) was used to evaluate body size estimates for oneself (self-estimation) and others (other-estimation). Participants also completed questionnaires assessing eating disorders and depressive symptoms. The AN and control groups scored significantly higher in self-estimation than in other-estimation. However, the AN group showed higher self-estimation scores than the control group for all the body parts and for the global silhouette (p < .001). Patients with more severe eating disorder symptomatology showed more distorted self-estimation (p < .05). No statistically significant differences were found in the other-estimation scores between the groups (p = .714), indicating that AN and control patients estimate the body sizes of others similarly. Eating disorder symptomatology correlates with self-estimation scores but not with other-estimation scores in adolescents with AN. No correlations existed between clinical symptomatology and other-estimation.

Perspectives of Implementation of Closed-Loop Deep Brain Stimulation: From Neurological to Psychiatric Disorders.

BACKGROUND: Deep brain stimulation (DBS) is a highly efficient, evidence-based therapy to alleviate symptoms and improve quality of life in movement disorders such as Parkinson's disease, essential tremor, and dystonia, which is also being applied in several psychiatric disorders, such as obsessive-compulsive disorder and depression, when they are otherwise resistant to therapy. SUMMARY: At present, DBS is clinically applied in the so-called open-loop approach, with fixed stimulation parameters, irrespective of the patients' clinical state(s). This approach ignores the brain states or feedback from the central nervous system or peripheral recordings, thus potentially limiting its efficacy and inducing side effects by stimulation of the targeted networks below or above the therapeutic level. KEY MESSAGES: The currently emerging closed-loop (CL) approaches are designed to adapt stimulation parameters to the electrophysiological surrogates of disease symptoms and states. CL-DBS paves the way for adaptive personalized DBS protocols. This review elaborates on the perspectives of the CL technology and discusses its opportunities as well as its potential pitfalls for both clinical and research use in neuropsychiatric disorders.

Construcciones sociales de la salud sexual en mujeres adolescentes de una comunidad rural / Social constructions of sexual health in adolescent women from a rural community / Construções sociais da saúde sexual em mulheres adolescentes de uma comunidade rural

Objetivo: Descubrir cuáles son las construcciones sociales en la salud sexual de las mujeres adolescentes de una comunidad rural. Material y Métodos: Estudio cualitativo fenomenológico hermenéutico, donde participaron mujeres adolescentes de 14 a 19 años, pertenecientes a la comunidad, El Molino, Ojuelos Jalisco, México. A través de un muestreo por cadena de referencia, se realizaron entrevistas fenomenológicas, transcritas de manera artesanal y anal-izadas mediante el "círculo hermenéutico Heiderggeriano". Se obtuvo la autorización mediante el consentimiento informado, así como el asentimiento por parte de los tutores. Se cumple un rigor metodológico a través de la trasparencia, transferibilidad, credibilidad y autenticidad. Resultados: Se realizaron 10 entrevistas afines a 10 adolescentes y se determinaron 6 unidades de significado a partir del análisis hermenéutico, de los cuales tres son ónticas; una realidad palpable a la desinformación sobre vida sexual, ideologías paternales adiestradas y falo centrismo como base central en la dinámica social. Y tres son ontológicas; Sesgo educativo, Discurso del lenguaje culturizado, finalmente tabúes y estigmas familiares. Conclusión: Las mujeres adolescentes de una comunidad rural viven una doble moral social. Así se demuestra un ineficiente conocimiento sobre salud sexual hasta ser un tema intrascendente, los padres son quienes influyen y toman decisiones sobre la educación, autonomía y forma de pensar.

Objective: Discover what the social constructions in the sexual health of adolescent women in a rural community. Material and Methods: A qualitative hermeneutic phenomenological study, involving adolescent women from 14 to 19 years old, belonging to the community, El Molino Ojuelos Jalisco, México. Through a reference chain sampling, phenomenological inter-views were carried out, transcribed by hand and analyzed through the "Heiderggerian herme-neutic circle". Authorization was obtained through informed consent, as well as the assent of the tutors. Complying with methodological rigor through transparency, transferability, credibility and authenticity. Results: 10 related interviews were carried out with 10 adolescents, and 6 units of meaning were determined from the hermeneutic analysis, of which three are ontic; a palpable reality to the ignorance of contraceptive methods, trained paternal ideologies and phallocentrism as a central basis in social dynamics. And three are ontological; Educational bias, cultured language discourse, finally taboos and family stigmas. Conclusion: Adolescent women from a rural community experience a double social standard. Thus, demonstrating an inefficient knowledge about sexual health until it is an insignificant issue, parents are the ones who influence and make decisions about education, autonomy and way of thinking

Resultados: foram realizadas 10 entrevistas relacionadas com 10 adolescentes e foram determinadas 6 unidades de significado a partir da análise hermenêutica, das quais três são ônticas; uma realidade palpável do desconhecimento dos métodos contraceptivos, das ideologias paternas treinadas e do falocentrismo como base central na dinâmica social. E três são ontológicos; Viés educacional, discurso de linguagem cul-turalizado, finalmente tabus e estigmas familiares. Conclusão: As mulheres adolescentes de uma comunidade rural vivenciam um duplo padrão social. Demonstrando assim um conhecimento ineficiente sobre saúde sexual a ponto de ser uma questão inconsequente, são os pais que influ-enciam e tomam decisões sobre educação, autonomia e modo de pensar
