The Applications of Artificial Intelligence for Assessing Fall Risk: Systematic Review.

BACKGROUND: Falls and their consequences are a serious public health problem worldwide. Each year, 37.3 million falls requiring medical attention occur. Therefore, the analysis of fall risk is of great importance for prevention. Artificial intelligence (AI) represents an innovative tool for creating predictive statistical models of fall risk through data analysis. OBJECTIVE: The aim of this review was to analyze the available evidence on the applications of AI in the analysis of data related to postural control and fall risk. METHODS: A literature search was conducted in 6 databases with the following inclusion criteria: the articles had to be published within the last 5 years (from 2018 to 2024), they had to apply some method of AI, AI analyses had to be applied to data from samples consisting of humans, and the analyzed sample had to consist of individuals with independent walking with or without the assistance of external orthopedic devices. RESULTS: We obtained a total of 3858 articles, of which 22 were finally selected. Data extraction for subsequent analysis varied in the different studies: 82% (18/22) of them extracted data through tests or functional assessments, and the remaining 18% (4/22) of them extracted through existing medical records. Different AI techniques were used throughout the articles. All the research included in the review obtained accuracy values of >70% in the predictive models obtained through AI. CONCLUSIONS: The use of AI proves to be a valuable tool for creating predictive models of fall risk. The use of this tool could have a significant socioeconomic impact as it enables the development of low-cost predictive models with a high level of accuracy.

Psychometric properties of the Spanish version of the Health of Nation Outcome Scales for schizophrenia patients.

Accessible Summary What is known on the subject? Functioning is one of the most affected areas in schizophrenia. Social, occupational and personal domains are affected, and these deficits are responsible for a major part of the disability associated with the disorder. There are several instruments to measure functioning, but the HoNOS provides a wide assessment of impairment in 12 areas of functioning. What does the paper add to existing knowledge? The Spanish version of the HoNOS shows good properties in terms of reliability and validity for use in schizophrenia patients. Although some authors divide the scale according to proposed underlying dimensions, in schizophrenia this division may not be appropriate. What are the implications for practice? A reliable and easy-to-use measure of impairment in different areas of functioning is useful for optimizing the treatment and rehabilitation of patients with schizophrenia. ABSTRACT: INTRODUCTION: The HoNOS scale was designed for the assessment of psychosocial impairment in various domains. While it is widely used in psychiatric settings, it has not been validated in Spanish for use in patients with schizophrenia. AIM: To examine the psychometric properties of the Spanish version of the HoNOS scale in a sample of schizophrenia patients. METHOD: A total of 194 individuals aged 18 to 65 with schizophrenia spectrum diagnoses were evaluated using the HoNOS. Illness severity and level of functioning were also assessed. RESULTS: The HoNOS showed moderate internal consistency, good inter-observer reliability and good test-retest reliability. Factor analysis revealed an internal structure consisting of four factors, with item distribution differing from the theoretical dimensions proposed for the original scale. DISCUSSION: The Spanish version of the HoNOS scale is a reliable and valid instrument for assessing psychosocial impairment in individuals diagnosed with schizophrenia spectrum disorders. However, further research is needed to determine its internal structure more accurately. IMPLICATIONS FOR PRACTICE: The HoNOS scale provides researchers and clinicians with a valid measure of impairment in twelve different domains, which can facilitate and guide the treatment of schizophrenia patients.

Resistencia a los inhibidores de la integrasa en niños con el virus de la inmunodeficiencia humana por transmisión vertical: primeros casos en Uruguay / Resistance to integrase inhibitors in children with vertically-transmitted human immunodeficiency virus: First cases in Uruguay

La resistencia a los antirretrovirales (ARV) es un problema de salud pública. Con el uso de inhibidores de la integrasa (INSTI) en pediatría, también comienzan a aparecer resistencias. El objetivo de esta comunicación es describir 3 casos con resistencia a los INSTI. Se describen 3 pacientes pediátricos con transmisión vertical del virus de la inmunodeficiencia humana (VIH). Iniciaron ARV de lactantes y preescolares, con mala adherencia al tratamiento, cursaron con diferentes planes secundarios a comorbilidades asociadas y fallas virológicas por resistencia. Los 3 casos clínicos describen la rápida aparición de resistencia frente a la falla virológica y el compromiso de los INSTI. La adherencia debe ser supervisada para detectar precozmente el aumento de la viremia. La falla virológica en un paciente tratado con raltegravir obliga a un rápido cambio de esquema ARV, ya que continuar utilizándolo podría favorecer nuevas mutaciones y resistencia a los INSTI de segunda generación.

Antiretroviral (ARV) drug resistance is a public health issue. Resistance has also been observed in the case of integrase strand transfer inhibitors (INSTIs) used in pediatrics. The objective of this article is to describe 3 cases of INSTI resistance. These are the cases of 3 children with vertically-transmitted human immunodeficiency virus (HIV). They were started on ARVs as infants and preschoolers, with poor treatment adherence, and had different management plans due to associated comorbidities and virological failure due to resistance. In the 3 cases, resistance developed rapidly as a result of virological failure and INSTI involvement. Treatment adherence should be monitored so that any increase in viremia can be detected early. Virological failure in a patient treated with raltegravir forces to a rapid change in ARV therapy because its continued use may favor new mutations and resistance to second-generation INSTIs.

Proposal for a physiotherapy assessment form for the evaluation of women patients with uro-gynecological disorders: A Delphi study.

BACKGROUND: The correct selection of treatment techniques and methods in physiotherapy depends directly on a well-structured anamnesis, examination and assessment. Within urogynecological and obstetric physiotherapy there is no standardized and protocolized assessment that allows to follow established steps. For all this, the main objective of this study was to identify the assessment items that should be included in the a physiotherapeutic uro-gynecological assessment. METHODS: Delphi study through a group of experts. Prior to this, a systematic search was carried out, accompanied by a review of grey literature, to obtain the possible items to be included in the forms. Subsequently, a Delphi study with two consecutive rounds of questionnaires was developed. A total of 6 expert physiotherapists participated in the study. RESULTS: The initial questionnaire had 97 items and after two rounds one item was eliminated to obtain a total of 96 items in the final questionnaire. CONCLUSIONS: The experts agreed on most of the choices and finally obtained a standardized and protocolized assessment in uro-gynecological physiotherapy. Furthermore, this proposal should be considered by other professionals involved in the process of evaluation and treatment of pelvi-perineal alterations.

Increased gut permeability and bacterial translocation are associated with fibromyalgia and myalgic encephalomyelitis/chronic fatigue syndrome: implications for disease-related biomarker discovery.

Background: There is growing evidence of the significance of gastrointestinal complaints in the impairment of the intestinal mucosal barrier function and inflammation in fibromyalgia (FM) and in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). However, data on intestinal permeability and gut barrier dysfunction in FM and ME/CFS are still limited with conflicting results. This study aimed to assess circulating biomarkers potentially related to intestinal barrier dysfunction and bacterial translocation and their association with self-reported symptoms in these conditions. Methods: A pilot multicenter, cross-sectional cohort study with consecutive enrolment of 22 patients with FM, 30 with ME/CFS and 26 matched healthy controls. Plasma levels of anti-beta-lactoglobulin antibodies (IgG anti-ß-LGB), zonulin-1 (ZO-1), lipopolysaccharides (LPS), soluble CD14 (sCD14) and interleukin-1-beta (IL-1ß) were assayed using ELISA. Demographic and clinical characteristics of the participants were recorded using validated self-reported outcome measures. The diagnostic accuracy of each biomarker was assessed using the receiver operating characteristic (ROC) curve analysis. Results: FM patients had significantly higher levels of anti-ß-LGB, ZO-1, LPS, and sCD14 than healthy controls (all P < 0.0001). In ME/CFS patients, levels of anti-ß-LGB, ZO-1, LPS, and sCD14 were significantly higher than controls, but lower than in FM (all P < 0.01), while there was no significant difference in IL-1ß level. In the FM and ME/CFS cohorts, both anti-ß-LGB and ZO-1 correlated significantly with LPS and sCD14 (P < 0.001 for both). In the FM group, both anti-ß-LGB and ZO-1 were correlated significantly with physical and mental health components on the SF-36 scale (P < 0.05); whereas IL-1ß negatively correlated with the COMPASS-31 score (P < 0.05). In the ME/CFS cohort, ZO-1 was positively correlated with the COMPASS-31 score (P < 0.05). The ROC curve analysis indicated a strong ability of anti-ß-LGB, ZO-1, LPS and sCD14 to predictively distinguish between FM and ME/CFS from healthy controls (P < 0.0001). Conclusion: Biomarkers of intestinal barrier function and inflammation were associated with autonomic dysfunction assessed by COMPASS-31 scores in FM and ME/CFS respectively. Anti-ß-LGB antibodies, ZO-1, LPS, and sCD14 may be putative predictors of intestinal barrier dysfunction in these cohorts. Further studies are needed to assess whether these findings are causal and can therefore be applied in clinical practice.

Genome-wide multi-trait analysis of irritable bowel syndrome and related mental conditions identifies 38 new independent variants.

BACKGROUND: Irritable bowel syndrome (IBS) is a chronic disorder of gut-brain interaction frequently accompanied by mental conditions, including depression and anxiety. Despite showing substantial heritability and being partly determined by a genetic component, the genetic underpinnings explaining the high rates of comorbidity remain largely unclear and there are no conclusive data on the temporal relationship between them. Exploring the overlapping genetic architecture between IBS and mental conditions may help to identify novel genetic loci and biological mechanisms underlying IBS and causal relationships between them. METHODS: We quantified the genetic overlap between IBS, neuroticism, depression and anxiety, conducted a multi-trait genome-wide association study (GWAS) considering these traits and investigated causal relationships between them by using the largest GWAS to date. RESULTS: IBS showed to be a highly polygenic disorder with extensive genetic sharing with mental conditions. Multi-trait analysis of IBS and neuroticism, depression and anxiety identified 42 genome-wide significant variants for IBS, of which 38 are novel. Fine-mapping risk loci highlighted 289 genes enriched in genes upregulated during early embryonic brain development and gene-sets related with psychiatric, digestive and autoimmune disorders. IBS-associated genes were enriched for target genes of anti-inflammatory and antirheumatic drugs, anesthetics and opioid dependence pharmacological treatment. Mendelian-randomization analysis accounting for correlated pleiotropy identified bidirectional causal effects between IBS and neuroticism and depression and causal effects of the genetic liability of IBS on anxiety. CONCLUSIONS: These findings provide evidence of the polygenic architecture of IBS, identify novel genome-wide significant variants for IBS and extend previous knowledge on the genetic overlap and relationship between gastrointestinal and mental disorders.

Acute Stress Regulates Sex-Related Molecular Responses in the Human Jejunal Mucosa: Implications for Irritable Bowel Syndrome.

Irritable bowel syndrome (IBS) is a prevalent gastrointestinal disorder linked to intestinal barrier dysfunction and life stress. We have previously reported that female sex per se determines an increased susceptibility to intestinal barrier dysfunction after cold pain stress (CPS). We aimed to identify sex-related molecular differences in response to CPS in healthy subjects to understand the origin of sex bias predominance in IBS. In 13 healthy males and 21 females, two consecutive jejunal biopsies were obtained using Watson's capsule, at baseline, and ninety minutes after CPS. Total mucosal RNA and protein were isolated from jejunal biopsies. Expression of genes related to epithelial barrier (CLDN1, CLDN2, OCLN, ZO-1, and ZO-3), mast cell (MC) activation (TPSAB1, SERPINA1), and the glucocorticoid receptor (NR3C1) were analyzed using RT-qPCR. NR3C1, ZO-1 and OCLN protein expression were evaluated through immunohistochemistry and western blot, and mucosal inflammation through MC, lymphocyte, and eosinophil numbering. Autonomic, hormonal, and psychological responses to CPS were monitored. We found an increase in jejunal MCs, a reduced CLDN1 and OCLN expression, and an increased CLDN2 and SERPINA1 expression 90 min after CPS. We also found a significant decrease in ZO-1, OCLN, and NR3C1 gene expression, and a decrease in OCLN protein expression only in females, when compared to males. CPS induced a significant increase in blood pressure, plasma cortisol and ACTH, and subjective stress perception in all participants. Specific and independent sex-related molecular responses in epithelial barrier regulation are unraveled by acute stress in the jejunum of healthy subjects and may partially explain female predominance in IBS.

Acute psychological stress increases paracellular permeability and modulates immune activity in rectal mucosa of healthy volunteers.

BACKGROUND: Psychological stress and increased permeability are implicated as contributing factors in the initiation and worsening of gastrointestinal diseases. A link between stress and intestinal permeability has been shown in animal models as well as in human small intestine, but stress effects on the human colorectal mucosal barrier has not been reported. OBJECTIVE: To investigate the potential effects of acute psychological stress on colorectal mucosal barrier function and to explore stress-induced molecular events in the rectal mucosa under healthy conditions. METHODS: Endoscopic biopsies were taken from the rectosigmoid region of healthy volunteers, who had been subjected to dichotomous listening stress and after a control session, respectively. Paracellular and transcellular permeability were assessed in modified Ussing chambers. RNA expression (microarray technology confirmed by quantitative real-time polymerase chain reaction) and biological pathway analysis were used to investigate the local mucosal response to acute stress. RESULTS: Dichotomous listening stress induced a subjective and objective stress response, and significantly increased paracellular but not transcellular permeability. We also identified a stress-induced reduction in RNA expression of genes related to immune cell activation and maturation (CR2, CD20, TCLA1, BANK1, CD22, FDCSP), signaling molecules of homing of immune cells to the gut (chemokines: CCL21, CXCL13, and CCL19, and receptors: CCR7, CXCR5), and innate immunity (DUOX2). Eight of the 10 top down-regulated genes are directly involved in B cell activation, signaling and migration. The systemic stress response correlated positively with paracellular permeability and negatively with DUOX2 expression. CONCLUSION: Dichotomous listening stress increases paracellular permeability and modulates immune cell activity in the rectal mucosa. Further studies are warranted to identify the primary mechanisms of stress-mediated reduction of mucosal defensive activity and barrier dysfunction, and their potential implications for gastrointestinal disorders.

Efectos del confinamiento sobre los hábitos saludables de adolescentes durante la pandemia de COVID-19 / Effects of confinement on the healthy habits of adolescents during the COVID-19 pandemic / Efeitos do confinamento nos hábitos saudáveis dos adolescentes durante a pandemia de COVID-19

Introducción: en marzo de 2020, en Uruguay se decretó la emergencia sanitaria al detectarse los primeros casos de infección por SARS-CoV-2 (COVID-19). El confinamiento domiciliario voluntario fue una de las medidas de salud pública adoptadas en el control de la pandemia. Objetivo: describir el efecto del confinamiento sobre los hábitos de sueño, alimentación y actividad física de adolescentes de Montevideo y Canelones durante la pandemia de COVID-19. Metodología: encuesta elaborada ad hoc, voluntaria, anónima, online y autoadministrada a adolescentes de 12 a 19 años, usuarios de CASMU, CRAMI, COMECA y Asociación Española, entre el 1 de junio y el 1 de julio de 2020. Se aplicaron cuestionarios validados para evaluar sueño, alimentación y actividad física. Resultados: se encuestaron 465 adolescentes, 70,1% mujeres y 48,2% de adolescencia media. Refirieron permanecer más de 6 horas al día conectados a internet y al celular 58,3% y 42,4%, respectivamente. La convivencia durante el confinamiento resultó agradable en la mayoría. El 76% refirió dormir menos de 9 horas/día. Señaló un consumo adecuado de frutas 6%, verduras 5,8% y lácteos 32,2%. El porcentaje de adolescentes activos descendió de 30,7% previo a la pandemia a 19,7% durante la misma. A la pregunta "¿cuál es la primera palabra que te viene a la mente cuando escuchas pandemia de COVID-19?" la mayoría brindó respuestas negativas. Conclusiones: las medidas de confinamiento no se asociaron con problemas importantes en la convivencia familiar en este grupo de adolescentes. Se observó una profundización de los problemas en los hábitos de alimentación, actividad física, sueño que favorecen el "ambiente obesogénico" y el riesgo de desarrollo de enfermedades crónicas no transmisibles. Resulta relevante considerar el impacto negativo del confinamiento y planificar las medidas preventivas tendientes a mitigar sus efectos.

Introduction: in March 2020, a Health Emergency was decreed in Uruguay when the first cases of the SARS-CoV-2 (COVID 19) infection were detected. Voluntary home confinement was one of the public health measures adopted in theto control the pandemic. Objectives: describe the effects of confinement on sleep, eating and exercise habits of adolescents assisted by private health providers in Montevideo and Canelones during the COVID-19 pandemic. Methodology: ad hoc, voluntary, anonymous, online and self-administered survey to adolescents of 12 to 19 years of age, users of CASMU, CRAMI, COMECA and Asociación Española HMOs, between June 1 and July 1, 2020. Validated questionnaires were applied to assess sleep, diet and exercise habits. Results: 465 adolescents were surveyed, 70.1% women and 48.2% in mid-adolescence. They reported having been connected to Internet and cell phone more than 6 hours a day, 58.3% and 42.4%, respectively. Coexistence during confinement was mostly pleasant. 76% reported sleeping less than 9 hours/day. They reported an appropriate consumption of fruit 6%, vegetables 5.8% and dairy 32.2%. The percentage of active adolescents fell from 30.7% before the pandemic to 19.7% during the pandemic. To the question, What is the first word that comes to mind when you hear about the COVID-19 pandemic? most gave negative responses. Conclusions: confinement measures were not linked to important problems regarding coexistence with relatives in this group of adolescents. We observed a worsening of the eating, exercise and sleep habits, which may favor the "obesogenic environment" and increase the risk of developing chronic non-communicable diseases. It is relevant to consider the negative impact of confinement and plan preventive measures aimed at mitigating its effects.

Se utilizó test de Chi cuadrado o exacto de Fisher. Nivel de significación: 0,05. Programa Epi Info™ versión 7.2. Consentimiento informado telefónico a padres y asentimiento a adolescentes. Aprobado por el Comité de Ética del CHPR. Resultados: consultaron 2.826 menores de 15 años, se incluyeron 426 (15%), pero solo 263 (62%) fueron analizados, dado que 163 (38%) no pudieron ser contactados telefónicamente. El 52% eran de sexo femenino. Media de edad: 4 años (5 días-14 años), 69% ≤5 años. 83% de los pacientes tenían adecuados controles de salud y 91% estaban al día con sus inmunizaciones. 12% tenían sobrepeso/obesidad. El desarrollo neurológico fue adecuado en 93% en los menores de 5 años y en 56% de los mayores de 5 años de edad. En el caso de aquellos con trastornos del neurodesarrollo mayores de 5 años, 46% tenían trastornos del aprendizaje, 39% trastorno de conducta, 32% trastornos del lenguaje, 10% déficit intelectual. 56% estaba escolarizado, todos en escuelas públicas. En el caso de aquellos que no asistían a la escuela, 4 estaban en edad de asistencia obligatoria (6, 7, 9 y 10 años de edad). 20% de los niños/adolescentes había repetido por lo menos un año en escuela o liceo. Datos perinatales: 14% de las madres consumieron drogas; las más frecuentes fueron tabaco y pasta base de cocaína (PBC). 85% fueron recién nacidos de término, 10% presentaron depresión neonatal. 15% de niños/ adolescentes estuvo expuesto a violencia doméstica y 32% de ellos (12/38) tenía por lo menos un padre con uso de drogas psicoactivas en el domicilio. 21% de los niños/adolescentes expuestos a violencia doméstica tenía una dificultad de aprendizaje. 8% de estos pacientes tenía por lo menos un padre que no había terminado educación primaria y 28% que no había terminado ciclo básico. Se encontró una relación significativa entre uso de drogas psicoactivas, declarada por uno o ambos padres, y violencia doméstica. No se encontró una relación significativa entre alteración del neurodesarrollo y violencia doméstica. Conclusiones: estos hallazgos muestran una población social y económicamente vulnerable, padres con baja escolaridad, uso de pasta base de cocaína durante el embarazo en un porcentaje mayor al reportado nacionalmente, y 15% de niños/adolescentes expuestos a violencia doméstica, pero con un buen número de controles de salud. La mayor fortaleza encontrada por este estudio es la importancia de mantener una buena conexión con estas familias, que mostraron un alto nivel de compromiso con el centro de salud. Esto nos desafía a priorizar la prevención y promoción en salud como herramientas valiosas para adquirir salud de calidad para estos niños/adolescentes. Nuevos estudios, con otras metodologías, serán necesarios para analizar estas variables encontradas.

Introduction: around 30% of childhood diseases are caused by social, environmental and family issues, as well as by life conditions, family dynamics and exposure to toxic substances. Understanding the characteristics of the pediatric population assisted at this Health Center, will help us identify health-threatening factors. Objectives: Describe the clinical and epidemiological characteristics of the population under 15 years of age assisted at Badano Repetto Health Center between 2020 and 2021. Understand the different variables that could influence this population´s health. Identify the link between family, social and cultural variables and neurological development at different ages. Methodology: descriptive, retrospective cross-sectional study. Convenience sampling of 15% of the total number of children and adolescents under 15 years of age, assisted at the Health Center from 10/01/2020 to 3/31/2021. Variables: children: sex, age, perinatal history, growth and neurological development, health checkups, vaccines, school attendance, extracurricular activities. Parents: age, education, psychoactive substance use, pathological background, job, prison. Family and household: parent`s marital status, domestic violence history, cohabitants, housing characteristics, basic household services, government aids, community interventions. Data source: medical records and telephone conversations. Data was recorded on template charts. We used results in absolute and relative frequencies, and their measures of central tendency measures and their range, Chi-square test or Fisher´s exact test. Significance level 0,05. Epi Info Program, version 7.2. Informed parent and adolescent consent. Approved by the CHPR Ethics Committee. Results: out of the 2826 patients under 15 years of age assisted at the clinic, we included 426 (15%), but only 263 (62%) were analyzed, since we were not able to reach 163 (38%) by phone. 52% were female. The average age was 4 years of age (5 days-14 years old). 69% of children were under 5 years old. 83% of patients had adequate number of checkups and 91% had an updated vaccination chart. 12% were overweight/obese. Neurodevelopment was adequate in 93% of those under 5 years of age, and 56% of those over 5 years of age. Regarding those with neurodevelopmental difficulties and over 5 years of age, 46% had learning disabilities, 39% had behavioral disorders, 32% language disorders, 10% intellectual deficit. 56% attended school, all of them public schools. For those who did not attend school, 4 of them were old enough to attend mandatory school (6, 7, 9 and 10 years of age). 20% of the children and adolescents had failed at least one year in school or high school. Perinatal findings: 14% of mothers had substance use during pregnancy, mainly tobacco and cocaine base paste. 85% of them had been born to term, 10% had neonatal depression 15% of children/adolescents had been exposed to domestic violence and 32% of them (12/38) had one parent with psychoactive drug use at home. 21% of children/adolescents exposed to domestic violence had a learning disability. 8% had at least one parent who did not finish primary school and 28% who did not finish middle school. Statistically, a significant link was found between psychoactive substance use, declared by one or both parents, and domestic violence. No statistically significant link was found between neurodevelopmental difficulties and domestic violence. Conclusions: these findings show a socially and economically vulnerable population, parents with little formal education, higher cocaine paste base use during pregnancy than the national statistics and 15% of children/adolescents exposed to domestic violence, even though they a high number of them had received their health checkups. The biggest strength shown by this study is the importance of maintaining a good bond with these families, who showed a high level of commitment with the health center. This leads us to prioritize health prevention and promotion as a valuable tool to achieve health quality standards for these children and adolescents. New studies, using other methodologies, will be necessary to analyze this data.

No caso dos portadores de transtornos de neurodesenvolvimento com mais de 5 anos, 46% apresentavam transtorno de aprendizagem, 39% transtorno de conduta, 32% transtorno de linguagem, 10% déficit intelectual. 56% estavam na escola, todos em escolas públicas. No caso dos que não frequentaram a escola, 4 deles estavam em idade em idade escolar obrigatória (6, 7, 9 e 10 anos). 20% das crianças/adolescentes repetiram pelo menos um ano na escola ou no ensino médio. Dados perinatais: 14% das mães usavam drogas; pasta base de tabaco e maiormente pasta base de cocaína (PBC). 85% eram recém-nascidos a termo, 10% tinham depressão neonatal. 15% das crianças/adolescentes foram expostos à violência doméstica e 32% deles (12/38) tinham pelo menos um dos pais que usava drogas psicoativas em casa. 21% das crianças/adolescentes expostas à violência doméstica tinham dificuldade de aprendizagem. 8% desses pacientes possuíam pelo menos um dos pais com escola primária incompleta e 28% com ensino médio incompleto. Encontrou-se relação significativa entre o uso de drogas psicoativas, declarado por um ou ambos os pais, e a violência doméstica. Não foi encontrada relação significativa entre transtornos do neurodesenvolvimento e violência doméstica. Conclusões: esses achados mostram uma população social e economicamente vulnerável, pais com baixa escolaridade, uso de pasta base de cocaína durante a gravidez em porcentagem superior ao reportado a nível nacional, e 15% de crianças/adolescentes expostos à violência doméstica, mas com um alto número de controles de saúde. A maior fortaleza encontrada por este estudo é a importância de manter um bom vínculo com essas famílias, que demonstraram alto nível de comprometimento com o centro de saúde. Isso nos leva a priorizar a prevenção e promoção da saúde como ferramentas valiosas para a aquisição de saúde de qualidade para essas crianças/adolescentes. Novos estudos, com outras metodologias, serão necessários para poder analisar essas variáveis encontradas.

Mucosal Plasma Cell Activation and Proximity to Nerve Fibres Are Associated with Glycocalyx Reduction in Diarrhoea-Predominant Irritable Bowel Syndrome: Jejunal Barrier Alterations Underlying Clinical Manifestations.

Irritable bowel syndrome (IBS) is a disorder of brain-gut interaction characterised by abdominal pain and changes in bowel habits. In the diarrhoea subtype (IBS-D), altered epithelial barrier and mucosal immune activation are associated with clinical manifestations. We aimed to further evaluate plasma cells and epithelial integrity to gain understanding of IBS-D pathophysiology. One mucosal jejunal biopsy and one stool sample were obtained from healthy controls and IBS-D patients. Gastrointestinal symptoms, stress, and depression scores were recorded. In the jejunal mucosa, RNAseq and gene set enrichment analyses were performed. A morphometric analysis by electron microscopy quantified plasma cell activation and proximity to enteric nerves and glycocalyx thickness. Immunoglobulins concentration was assessed in the stool. IBS-D patients showed differential expression of humoral pathways compared to controls. Activation and proximity of plasma cells to nerves and IgG concentration were also higher in IBS-D. Glycocalyx thickness was lower in IBS-D compared to controls, and this reduction correlated with plasma cell activation, proximity to nerves, and clinical symptoms. These results support humoral activity and loss of epithelial integrity as important contributors to gut dysfunction and clinical manifestations in IBS-D. Additional studies are needed to identify the triggers of these alterations to better define IBS-D pathophysiology.

Present and Future Therapeutic Approaches to Barrier Dysfunction.

There is converging and increasing evidence, but also uncertainty, for the role of abnormal intestinal epithelial barrier function in the origin and development of a growing number of human gastrointestinal and extraintestinal inflammatory disorders, and their related complaints. Despite a vast literature addressing factors and mechanisms underlying changes in intestinal permeability in humans, and its connection to the appearance and severity of clinical symptoms, the ultimate link remains to be established in many cases. Accordingly, there are no directives or clinical guidelines related to the therapeutic management of intestinal permeability disorders that allow health professionals involved in the management of these patients to carry out a consensus treatment based on clinical evidence. Instead, there are multiple pseudoscientific approaches and commercial propaganda scattered on the internet that confuse those affected and health professionals and that often lack scientific rigor. Therefore, in this review we aim to shed light on the different therapeutic options, which include, among others, dietary management, nutraceuticals and medical devices, microbiota and drugs, and epigenetic and exosomes-manipulation, through an objective evaluation of the scientific publications in this field. Advances in the knowledge and management of intestinal permeability will sure enable better options of dealing with this group of common disorders to enhance quality of life of those affected.

The Role of Purported Mucoprotectants in Dealing with Irritable Bowel Syndrome, Functional Diarrhea, and Other Chronic Diarrheal Disorders in Adults.

Chronic diarrhea is a frequent presenting symptom, both in primary care medicine and in specialized gastroenterology units. It is estimated that more than 5% of the global population suffers from chronic diarrhea. and that about 40% of these subjects are older than 60 years. The clinician is frequently faced with the need to decide which is the best therapeutic approach for these patients. While the origin of chronic diarrhea is diverse, impairment of intestinal barrier function, dysbiosis. and mucosal micro-inflammation are being increasingly recognized as underlying phenomena characterizing a variety of chronic diarrheal diseases. In addition to current pharmacological therapies, there is growing interest in alternative products such as mucoprotectants, which form a mucoadhesive film over the epithelium to reduce and protect against the development of altered intestinal permeability, dysbiosis, and mucosal micro-inflammation. This manuscript focuses on chronic diarrhea in adults, and we will review recent evidence on the ability of these natural compounds to improve symptoms associated with chronic diarrhea and to exert protective effects for the intestinal barrier.

Overexpression of corticotropin-releasing factor in intestinal mucosal eosinophils is associated with clinical severity in Diarrhea-Predominant Irritable Bowel Syndrome.

Corticotropin-releasing factor (CRF) has been identified in intestinal mucosal eosinophils and associated with psychological stress and gut dysfunction. Irritable bowel syndrome (IBS) is commonly characterized by altered intestinal motility, immune activation, and increased gut barrier permeability along with heightened susceptibility to psychosocial stress. Despite intensive research, the role of mucosal eosinophils in stress-associated gut dysfunction remains uncertain. In this study, we evaluated eosinophil activation profile and CRF content in the jejunal mucosa of diarrhea-predominant IBS (IBS-D) and healthy controls (HC) by gene/protein expression and transmission electron microscopy. We also explored the association between intestinal eosinophil CRF and chronic stress, and the potential mechanisms underlying the stress response by assessing eosinophil response to neuropeptides. We found that mucosal eosinophils displayed higher degranulation profile in IBS-D as compared to HC, with increased content of CRF in the cytoplasmic granules, which significantly correlated with IBS clinical severity, life stress background and depression. Eosinophils responded to substance P and carbachol by increasing secretory activity and CRF synthesis and release, without promoting pro-inflammatory activity, a profile similar to that found in mucosal eosinophils from IBS-D. Collectively, our results suggest that intestinal mucosal eosinophils are potential contributors to stress-mediated gut dysfunction through CRF production and release.

Peripheral Corticotropin-Releasing Factor Triggers Jejunal Mast Cell Activation and Abdominal Pain in Patients With Diarrhea-Predominant Irritable Bowel Syndrome.

INTRODUCTION: To determine the effect of peripheral CRF on intestinal barrier function in diarrhea-predominant IBS (IBS-D). Irritable bowel syndrome (IBS) pathophysiology has been linked to life stress, epithelial barrier dysfunction, and mast cell activation. Corticotropin-releasing factor (CRF) is a major mediator of stress responses in the gastrointestinal tract, yet its role on IBS mucosal function remains largely unknown. METHODS: Intestinal response to sequential i.v. 5-mL saline solution (placebo) and CRF (100 µg) was evaluated in 21 IBS-D and 17 healthy subjects (HSs). A 20-cm jejunal segment was perfused with an isosmotic solution and effluents collected at baseline, 30 minutes after placebo, and 60 minutes after CRF. We measured water flux, albumin output, tryptase release, stress hormones, cardiovascular and psychological responses, and abdominal pain. A jejunal biopsy was obtained for CRF receptor expression assessment. RESULTS: Water flux did not change after placebo in IBS-D and HS but significantly increased after CRF in IBS-D (P = 0.007). Basal luminal output of albumin was higher in IBS-D and increased further after CRF in IBS-D (P = 0.042). Basal jejunal tryptase release was higher in IBS-D, and CRF significantly increased it in both groups (P = 0.004), the response being higher in IBS-D than in HS (P = 0.0023). Abdominal pain worsened only in IBS-D after CRF and correlated with jejunal tryptase release, water flux, and albumin output. IBS-D displayed jejunal up-regulation of CRF2 and down-regulation of CRF1 compared with HS. DISCUSSION: Stress via CRF-driven mast cell activation seems to be relevant in the pathophysiology of IBS-D.

Increased Colonic Epithelial Permeability and Mucosal Eosinophilia in Ulcerative Colitis in Remission Compared With Irritable Bowel Syndrome and Health.

BACKGROUND: Barrier dysfunction is recognized as a pathogenic factor in ulcerative colitis (UC) and irritable bowel syndrome (IBS), but it is unclear to what extent the factors related to barrier dysfunction are disease-specific. The aim of this study was to compare these aspects in UC patients in remission, IBS patients, and healthy controls (HCs). METHODS: Colonic biopsies were collected from 13 patients with UC in remission, 15 patients with IBS-mixed, and 15 HCs. Ulcerative colitis patients had recently been treated for relapse, and biopsies were taken from earlier inflamed areas. Biopsies were mounted in Ussing chambers for measurements of intestinal paracellular permeability to 51chromium (Cr)-ethylenediaminetetraacetic acid (EDTA). In addition, biopsies were analyzed for mast cells and eosinophils by histological procedures, and plasma tumor necrosis factor (TNF)-α was assessed by ELISA. RESULTS: Ussing chamber experiments revealed an increased 51Cr-EDTA permeability in UC and IBS (P < 0.05). The 51Cr-EDTA permeability was higher in UC compared with IBS (P < 0.005). There were increased numbers of mucosal mast cells and eosinophils in UC and IBS and more eosinophils in UC compared with IBS (P < 0.05). Also, increased extracellular granule content was found in UC compared with HCs (P < 0.05). The 51Cr-EDTA permeability correlated significantly with eosinophils in all groups. Plasma TNF-α concentration was higher in UC compared with IBS and HCs (P < 0.0005). CONCLUSIONS: Results indicate a more permeable intestinal epithelium in inactive UC and IBS compared with HCs. Ulcerative colitis patients, even during remission, demonstrate a leakier barrier compared with IBS. Both eosinophil numbers and activation state might be involved in the increased barrier function seen in UC patients in remission.
