RESUMO
Introdução: A segurança e eficácia do uso de medicamentos durante a lactação são preocupações para mães e profissionais de saúde. Esta pesquisa analisa as orientações das bulas de medicamentos comumente prescritos para dispepsia e constipação, que visa fornecer informações essenciais para orientar as decisões terapêuticas durante esse período crucial da maternidade. Objetivos: Analisar as informações das bulas sobre contraindicações de medicamentos para dispepsia e constipação durante a amamentação, verificando se estão de acordo com as evidências científicas. Métodos: Medicamentos para dispepsia e constipação foram selecionados de acordo com a classificação da Anatomical Therapeutic Chemical (ATC) e o registro ativo no Brasil. A presença de contraindicações para o uso de medicamentos nas bulas do profissional de saúde e do paciente foi comparada com as informações contidas no manual técnico do Ministério da Saúde, Medicamentos e Leite Materno, LactMed, UptoDate, Micromedex, Documento Científico da Sociedade Brasileira de Pediatria e Reprotox. Resultados: Nenhuma informação sobre o uso durante a amamentação foi encontrada em 20,0 e 24,3% das bulas para dispepsia e constipação, respectivamente. A concordância entre as bulas dos medicamentos para dispepsia e as fontes consultadas foi baixa (27,2% das bulas contraindicavam o medicamento na lactação, enquanto nas fontes o percentual de contraindicação variou de 0 a 8,3%). Com relação a medicamentos para constipação, 26,3% das bulas os contraindicavam, enquanto nas fontes o percentual variou de 0 a 4,8%. Conclusões: O estudo mostrou que pelo menos duas em cada dez bulas para dispepsia e constipação não fornecem informações adequadas sobre o uso desses medicamentos em lactentes, e também que houve baixa concordância entre o texto das bulas e as fontes de referência quanto à compatibilidade do medicamento com a amamentação.
Introduction: The safety and effectiveness of medication use during lactation are concerns for mothers and healthcare professionals. This research analyzes the instructions on the leaflets of medications commonly prescribed for dyspepsia and constipation, which aims to provide essential information to guide therapeutic decisions during this crucial period of motherhood. Objectives: To analyze the information in package inserts about contraindications of drugs for dyspepsia and constipation during breastfeeding, verifying whether these are consistent with scientific evidence. Methods: Drugs for dyspepsia and constipation were selected according to the Anatomical Therapeutic Chemical (ATC) classification and active registry in Brazil. The presence of contraindications for the use of medications in the health professional's and patient's package inserts was compared with the information in the technical manual of the Ministry of Health, Medications and Mothers' Milk, LactMed, UptoDate, Micromedex, Documento Científico da Sociedade Brasileira de Pediatria and Reprotox. Results: No information about use during breastfeeding was found in 20.0 and 24.3% of leaflets for dyspepsia and constipation, respectively. The agreement between the leaflets of medications for dyspepsia and the sources consulted was low (27.2% of the leaflets contraindicated the medication during lactation, while in the sources the percentage of contraindication varied from 0 to 8.3%). In relation to medicines for constipation, 26.3% of the leaflets contraindicated them, while in the sources the percentage ranged from 0 to 4.8%. Conclusions: The study pointed out that at least two out of every ten package inserts for dyspepsia and constipation do not provide adequate information on the use of these drugs in infants, and also shows low concordance between the text of the package inserts and the reference sources regarding compatibility of the drug with breastfeeding.

OBJECTIVE: This study evaluated anthropometric, biochemical, and inflammatory biomarkers, as well as dietary intake in Brazilian children diagnosed with small intestinal bacterial overgrowth (SIBO) and compared them with their counterparts without SIBO. METHODS: This was a cross-sectional study with 106 children aged 7 to 10 years. A glucose-hydrogen breath test was performed to diagnose small intestinal bacterial overgrowth (SIBO). Anthropometric and dietary characteristics were assessed. Blood samples were collected and serum biochemical parameters and cytokines were measured. RESULTS: The occurrence of SIBO was 13.2%. Age, BMI, BMI/age WC, BFP, sex and biochemical markers were similar between SIBO-positive and SIBO-negative children (p > 0.05). High consumption of ultra-processed foods tended to be higher in SIBO-positive compared to SIBO-negative children (47.8 ± 8.2 vs. 42.6 ± 9.5, p = 0.06). Serum levels of IL-17 were higher in SIBO-positive than in SIBO-negative children [69.5 (5.4-125.7) vs. 53.4 (2.3-157.7), p = 0.03], while serum levels of IL-10 were lower in SIBO-positive than in SIBO-negative children [2.3 (0.6-7.2) vs. 5.7 (0.5-30.8), p = 0.04]. Finally, in a logistic regression adjusted for sex, BMI and age, consumption of ultra-processed foods (p = 0.03) and IL-6 levels (p = 0.003) were found to contribute to the occurrence of SIBO. CONCLUSION: this study identified for the first time an occurrence of 13% of SIBO in children living in the northeastern region of Brazil and showed that consumption of ultra-processed foods and serum levels of IL-6 may influence the occurrence of the SIBO in the pediatrics population.

The Short Bowel Syndrome (SBS) Registry (NCT01990040) is a multinational real-world study evaluating the long-term safety of teduglutide in patients with SBS and intestinal failure (SBS-IF) in routine clinical practice. This paper describes the study methodology and baseline characteristics of adult patients who have (ever-treated) or have never (never-treated) received teduglutide. A total of 1411 adult patients (679 ever-treated; 732 never-treated) were enrolled at 124 sites across 17 countries. The mean (standard deviation [SD]) age at enrollment was 55.4 (15.46) years, and 60.2% of patients were women. Crohn's disease was the most common cause of major intestinal resection in both ever-treated (34.1%) and never-treated patients (20.4%). A similar proportion of ever-treated and never-treated patients had a prior history of colorectal polyps (2.7% vs. 3.6%), whereas proportionally fewer ever-treated patients reported a history of colorectal cancer (1.8% vs. 6.2%) or any malignancy (17.7% vs. 30.0%) than never-treated patients. Never-treated patients received a numerically greater mean (SD) volume of parenteral nutrition and/or intravenous fluids than ever-treated patients (12.4 [8.02] vs. 10.1 [6.64] L/week). Ever-treated patients received a mean teduglutide dosage of 0.05 mg/kg/day. This is the first report of patient baseline characteristics from the SBS Registry, and the largest cohort of patients with SBS-IF to date. Overall, ever-treated and never-treated patients had similar baseline characteristics. Differences between treatment groups may reflect variations in patient selection and degree of monitoring.

Histoplasmosis is an increasing infection that mainly affects immunocompromised individuals such as patients with HIV/AIDS, with the disseminated form, especially gastrointestinal, being common in this population. The clinical presentation ranges from asymptomatic to symptoms that mimic other abdominal diseases. Jejunal perforation due to histoplasmosis, although rare, has been reported in a few cases, typically in men living with HIV in their fourth decade of life. We present the case of a 34-year-old male, with a history of HIV and colonic histoplasmosis who presented with acute abdominal pain requiring exploratory laparotomy and intestinal resection due to jejunal perforation, with histological confirmation of histoplasmosis in the resected intestinal segment.
RESUMO
Alterations of the microbiota-gut-brain axis has been associated with intestinal and neuronal inflammation in Parkinson's disease (PD). The aim of this work was to study some mechanisms associated with the neuroprotective effect of a combination (MIX) of lactic acid bacteria (LAB) composed by Lactiplantibacillus plantarum CRL2130 (riboflavin overproducing strain), Streptococcus thermophilus CRL808 (folate producer strain), and CRL807 (immunomodulatory strain) in cell cultures and in a chronic model of parkinsonism induced with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) in aged mice, and under levodopa-benserazide treatment. In vitro, N2a differentiated neurons were exposed to the neurotoxin 1-methyl-4-phenylpyridinium (MPP+) and treated with intracellular bacterial extracts or with conditioned media from BV-2 cells exposed to the bacterial extracts. In vivo, motor skills, tyrosine hydrolase (TH) in brain and cytokine concentrations in serum and in brain were evaluated. The study of the faecal microbiota and the histology of the small intestine was also performed. The results showed that the neuroprotective effect associated with LAB MIX administration did not interfere with levodopa-benserazide treatment. This effect could be associated with the antioxidant and immunomodulatory potential of the LAB selected in the MIX, and was associated with the significant improvement in the motor tests and a higher number of TH + cells in the brain. In addition, LAB MIX administration was associated with modulation of the immune response. LAB administration decreased intestinal damage with an increase in the villus length /crypt depth ratio. Finally, the administration of the LAB MIX in combination with levodopa-benserazide treatment was able to partially revert the intestinal dysbiosis observed in the model, showing greater similarity to the profiles of healthy controls, and highlighting the increase in the Lactobacillaceae family. Different mechanisms of action would be related to the protective effect of the selected LAB combination which has the potential to be evaluated as an adjuvant for conventional PD therapies.

A T-cell-independent (TI) pathway activated by microbiota results in the generation of low-affinity homeostatic IgA with a critical role in intestinal homeostasis. Moderate aerobic exercise (MAE) provides a beneficial impact on intestinal immunity, but the action of MAE on TI-IgA generation under senescence conditions is unknown. This study aimed to determine the effects of long-term MAE on TI-IgA production in young (3 month old) BALB/c mice exercised until adulthood (6 months) or aging (24 months). Lamina propria (LP) from the small intestine was obtained to determine B cell and plasma cell sub-populations by flow cytometry and molecular factors related to class switch recombination [Thymic Stromal Lymphopoietin (TSLP), A Proliferation-Inducing Ligand (APRIL), B Cell Activating Factor (BAFF), inducible nitric oxide synthase (iNOS), and retinal dehydrogenase (RDH)] and the synthesis of IgA [α-chain, interleukin (IL)-6, IL-21, and Growth Factor-ß (TGF-ß)]; and epithelial cells evaluated IgA transitosis [polymeric immunoglobulin receptor (pIgR), tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), IL-4] by the RT-qPCR technique. The results were compared with data obtained from sedentary age-matched mice. Statistical analysis was computed with ANOVA, and p < 0.05 was considered to be a statistically significant difference. Under senescence conditions, MAE promoted the B cell and IgA+ B cells and APRIL, which may improve the intestinal response and ameliorate the inflammatory environment associated presumably with the downmodulation of pro-inflammatory mediators involved in the upmodulation of pIgR expression. Data suggested that MAE improved IgA and downmodulate the cytokine pro-inflammatory expression favoring homeostatic conditions in aging.

We describe cases of intestinal failure wherein inpatient admission was critical toward enteral autonomy. We performed a retrospective chart review of 6 children with long-term parenteral nutrition dependence who were weaned from parenteral nutrition after admission. Admissions included feeding and medication titration, interdisciplinary care, and a home parenteral nutrition team consultation.
RESUMO
Neonatal immune activation (NIA) through exposure to lipopolysaccharide (LPS) induces adult behavioral changes in rodents that resemble symptoms of developmental disorders, such as autism spectrum disorder. The neonatal timing of LPS exposure appears to play a crucial role in determining the nature and extent of long-term changes. This study aims to explore whether a 3-day LPS-NIA triggers sex- and age-related changes in gut function, potentially linking LPS-NIA to gastrointestinal dysfunction. Male and female Swiss mice received intraperitoneal injections of LPS or saline on postnatal days (PN) 3, 5, and 7. At PN35 (juvenile) and PN70 (adult), gut inflammation and oxidative stress were evaluated in addition to assessments of working memory, depressive-like symptoms, sociability, and repetitive behavior. Gut examination showed elevated C-X-C motif chemokine receptor 3 (CXCR3) in LPS-NIA mice, while MyD88 and Zonulin expressions were significantly higher only in adult LPS-NIA females. Interleukin (IL)-23 expression increased in juvenile and adult male and juvenile female LPS-NIA mice. Oxidative changes included decreased duodenal reduced glutathione (GSH) in juvenile females and ileal GSH in adult females exposed to LPS-NIA. Regarding behavioral alterations, adult LPS-NIA females exhibited depressive-like behavior. Working memory deficits were observed across all LPS-NIA groups. Only juvenile LPS-NIA females increased grooming, while rearing was higher in adult LPS-NIA mice of both sexes. The findings imply that LPS-NIA impacts intestinal barrier function and causes gut inflammatory alterations that are sex- and age-specific. These findings pave the way for exploring potential mechanisms that could contribute to LPS-induced gastrointestinal disturbances among individuals with ASD.

BACKGROUND: In this study, a probiotic mixture (Honeybeeotic) consisting of seven bacterial strains isolated from a unique population of honeybees (Apis mellifera ligustica) was used. That honeybee population was located in the Roti Abbey locality of the Marche Region in Italy, an area isolated from human activities, and genetic contamination from other honeybee populations. The aim was to investigate the effects of this probiotic mixture on the innate immunity and intestinal microbiome of healthy common honeybees in two hives of the same apiary. Hive A received a diet of 50% glucose syrup, while hive B received the same syrup supplemented with the probiotics, both administered daily for 1 month. To determine whether the probiotic altered the immune response, phenoloxidase activity and hemolymph cellular subtype count were investigated. Additionally, metagenomic approaches were used to analyze the effects on gut microbiota composition and function, considering the critical role the gut microbiota plays in modulating host physiology. RESULTS: The results revealed differences in hemocyte populations between the two hives, as hive A exhibited higher counts of oenocytoids and granulocytes. These findings indicated that the dietary supplementation with the probiotic mixture was safe and well-tolerated. Furthermore, phenoloxidase activity significantly decreased in hive B (1.75 ± 0.19 U/mg) compared to hive A (3.62 ± 0.44 U/mg, p < 0.005), suggesting an improved state of well-being in the honeybees, as they did not require activation of immune defense mechanisms. Regarding the microbiome composition, the probiotic modulated the gut microbiota in hive B compared to the control, retaining core microbiota components while causing both positive and negative variations. Notably, several genes, particularly KEGG genes involved in amino acid metabolism, carbohydrate metabolism, and branched-chain amino acid (BCAA) transport, were more abundant in the probiotic-fed group, suggesting an effective nutritional supplement for the host. CONCLUSIONS: This study advocated that feeding with this probiotic mixture induces beneficial immunological effects and promoted a balanced gut microbiota with enhanced metabolic activities related to digestion. The use of highly selected probiotics was shown to contribute to the overall well-being of the honeybees, improving their immune response and gut health.

BACKGROUND: The Gran Chaco ecoregion is a well-known hotspot of several neglected tropical diseases (NTDs) including Chagas disease, soil-transmitted helminthiasis and multiparasitic infections. Interspecific interactions between parasite species can modify host susceptibility, pathogenesis and transmissibility through immunomodulation. Our objective was to test the association between human co-infection with intestinal parasites and host parasitaemia, infectiousness to the vector and immunological profiles in Trypanosoma cruzi-seropositive individuals residing in an endemic region of the Argentine Chaco. METHODS: We conducted a cross-sectional serological survey for T. cruzi infection along with an intestinal parasite survey in two adjacent rural villages. Each participant was tested for T. cruzi and Strongyloides stercoralis infection by serodiagnosis, and by coprological tests for intestinal parasite detection. Trypanosoma cruzi bloodstream parasite load was determined by quantitative PCR (qPCR), host infectiousness by artificial xenodiagnosis and serum human cytokine levels by flow cytometry. RESULTS: The seroprevalence for T. cruzi was 16.1% and for S. stercoralis 11.5% (n = 87). We found 25.3% of patients with Enterobius vermicularis. The most frequent protozoan parasites were Blastocystis spp. (39.1%), Giardia lamblia (6.9%) and Cryptosporidium spp. (3.4%). Multiparasitism occurred in 36.8% of the examined patients. Co-infection ranged from 6.9% to 8.1% for T. cruzi-seropositive humans simultaneously infected with at least one protozoan or helminth species, respectively. The relative odds of being positive by qPCR or xenodiagnosis (i.e. infectious) of 28 T. cruzi-seropositive patients was eight times higher in people co-infected with at least one helminth species than in patients with no such co-infection. Trypanosoma cruzi parasite load and host infectiousness were positively associated with helminth co-infection in a multiple regression analysis. Interferon-gamma (IFN-γ) response, measured in relation to interleukin (IL)-4 among humans infected with T. cruzi only, was 1.5-fold higher than for T. cruzi-seropositive patients co-infected with helminths. The median concentration of IL-4 was significantly higher in T. cruzi-seropositive patients with a positive qPCR test than in qPCR-negative patients. CONCLUSIONS: Our results show a high level of multiparasitism and suggest that co-infection with intestinal helminths increased T. cruzi parasitaemia and upregulated the Th2-type response in the study patients.

Introducción La obstrucción intestinal es la alteración del flujo del contenido luminal del tracto gastrointestinal debido a factores mecánicos. Los casos graves pueden evolucionar a shock séptico refractario con alta mortalidad. Para esta afección se han propuesto terapias innovadoras que pueden cambiar el pronóstico. Reporte: Un paciente masculino de 62 años presenta un cuadro de obstrucción intestinal acompañado de sepsis. La laparotomía exploratoria revela un tumor en el colon descendente y necrosis extensa del colon, requiriendo resección colónica e ileostomía. A pesar de la intervención, el paciente desarrolla choque séptico refractario y falla multiorgánica, con un pronóstico grave. Se implementa terapia de hemoadsorción de citoquinas e inmunoglobulina G enriquecida con inmunoglobulina M dentro de las primeras 32 horas. Se presenta posteriormente recuperación progresiva de parámetros clínicos y de laboratorio, asimismo como estado general. Conclusiones: La terapia hemoadsorción puede reducir la dosis de vasopresores, mejorar la hemodinamia y reducir los marcadores inflamatorios en pacientes con sepsis. La pentaglobina puede reducir el riesgo de mortalidad, disminuir la duración de la ventilación mecánica y mejorar la función renal en pacientes con sepsis. (provisto por Infomedic International)
Introduction Intestinal obstruction is the alteration of the flow of the luminal contents of the gastrointestinal tract due to mechanical factors. Severe cases may progress to refractory septic shock with high mortality. Innovative therapies have been proposed for this condition that may change the prognosis. Report: A 62-year-old male patient presents with intestinal obstruction accompanied by sepsis. Exploratory laparotomy reveals a tumor in the descending colon and extensive colon necrosis, requiring colonic resection and ileostomy. Despite the intervention, the patient develops refractory septic shock and multiorgan failure, with a severe prognosis. Cytokine hemoadsorption therapy and immunoglobulin G enriched with immunoglobulin M were implemented within the first 32 hours. Progressive recovery of clinical and laboratory parameters is subsequently presented, as well as general condition. Conclusions: Hemoadsorption therapy can reduce the dose of vasopressors, improve hemodynamics and reduce inflammatory markers in patients with sepsis. Pentaglobin can reduce the risk of mortality, decrease the duration of mechanical ventilation and improve renal function in patients with sepsis. (provided by Infomedic International)
RESUMO
Introducción: Existe una conexión bidireccional entre mecanismos fisiológicos del intestino y la piel que puede asociarse al desarrollo de patologias cutâneas. Objetivo: Estudiar la relación entre afecciones cutáneas con la presencia de patógenos intestinales causantes de disbiosis intestinal. Metodología: Se realizó un estudio para identificar la presencia de bacterias aeróbicas y anaeróbicas facultativas en un grupo de 45 pacientes (edad de 32,8 ± 18 años) que presentaron distintas afecciones cutáneas diagnosticadas en la consulta de Dermatología de UNIMEL, Caracas, Venezuela. La presencia de bacterias se determinó por cultivo diferencial, y la identificación de microorganismos mediante pruebas bioquímicas convencionales, prueba de filamentización en suero, medios automatizados (VITEK® 2 Compact) y pruebas de aglutinación. Se realizó un análisis estadístico descriptivo de la abundancia relativa de la microbiota gastrointestinal asociada a las afecciones cutáneas presentes (GraphPad Prism versión 8.0.2 para Windows) y análisis multivariado (NMDS) con (software PAST v4.13). Resultados: La presencia de acné, dermatitis atópica y nevus se asoció (p<0.05) al aumento de las colonias de Enterococcus faecium, E. coli, Enteroccocus faecalis y Klepsiella sp. Una disminución significativa en el número de colonias de E. coli (p<0.05) se asoció con la presencia de rosácea y acné inflamatorio mientras que su abundancia se asoció a la presencia de patologías como acantosis nigicans, dermatitis atópica, dermatitis papular y queratosis. La presencia de pseudomonas se relacionó con queratosis y Nevus melanocítico. Conclusión: Aunque preliminares, estos resultados sugieren que alteraciones en la composición microbiana intestinal pueden asociarse significativamente a afecciones cutáneas.
Introduction: There is a bidirectional connection between physiological mechanisms of the intestine and the skin that can be associated with the development of skin pathologies. Objective: To study the relationship between skin conditions with the presence of intestinal pathogens that cause intestinal dysbiosis. Methodology: A study was carried out to identify the presence of aerobic and facultative anaerobic bacteria in a group of 45 patients (age 32.8 ± 18 years) who presented different skin conditions diagnosed in the Dermatology clinic of UNIMEL, Caracas, Venezuela. The presence of bacteria was determined by differential culture, and the identification of microorganisms by conventional biochemical tests, serum filamentation test, automated media (VITEK® 2 Compact) and agglutination tests. A descriptive statistical analysis of the relative abundance of the gastrointestinal microbiota associated with the present skin conditions was performed (GraphPad Prism version 8.0.2 for Windows) and multivariate analysis (NMDS) with (PAST v4.13 software). Results: The presence of acne, atopic dermatitis and nevus was associated (p<0.05) with the increase in colonies of Enterococcus faecium, E. coli, Enteroccocus faecalis and Klepsiella sp. A significant decrease in the number of E. coli colonies (p<0.05) was associated with the presence of rosacea and inflammatory acne while its abundance was associated with the presence of pathologies such as acanthosis nigicans, atopic dermatitis, papular dermatitis and keratosis. The presence of pseudomonas was related to keratosis and melanocytic nevus. Conclusion: Although preliminary, these results suggest that alterations in intestinal microbial composition can be significantly associated with skin conditions.

Una disminución significativa en el número de colonias de E. coli (p<0.05) se asoció con la presencia de rosácea y acné inflamatorio mientras que su abundancia se asoció a la presencia de patologías como acantosis nigicans, dermatitis atópica, dermatitis papular y queratosis. La presencia de pseudomonas se relacionó con queratosis y Nevus melanocítico. Conclusión: aunque preliminares, estos resultados sugieren que alteraciones en la composición microbiana intestinal pueden asociarse significativamente a afecciones cutáneas
Introduction: There is a bidirectional connection between physiological mechanisms of the intestine and the skin that can be associated with the development of skin pathologies. Objective: To study the relationship between skin conditions with the presence of intestinal pathogens that cause intestinal dysbiosis. Methodology: a study was carried out to identify the presence of aerobic and facultative anaerobic bacteria in a group of 45 patients (age 32.8 ± 18 years) who presented different skin conditions diagnosed in the Dermatology clinic of UNIMEL, Caracas, Venezuela. The presence of bacteria was determined by differential culture, and the identification of microorganisms by conventional biochemical tests, serum filamentation test, automated media (VITEK® 2 Compact) and agglutination tests. A descriptive statistical analysis of the relative abundance of the gastrointestinal microbiota associated with the present skin conditions was performed (GraphPad Prism version 8.0.2 for Windows) and multivariate analysis (NMDS) with (PAST v4.13 software). Results: the presence of acne, atopic dermatitis and nevus was associated (p<0.05) with the increase in colonies of Enterococcus faecium, E. coli, Enteroccocus faecalis and Klepsiella sp. A significant decrease in the number of E. coli colonies (p<0.05) was associated with the presence of rosacea and inflammatory acne while its abundance was associated with the presence of pathologies such as acanthosis nigicans, atopic dermatitis, papular dermatitis and keratosis. The presence of pseudomonas was related to keratosis and melanocytic nevus. Conclusion: although preliminary, these results suggest that alterations in intestinal microbial composition can be significantly associated with skin conditions.

RESUMO
Introduction: Atrophic gastritis and intestinal metaplasia are precursor lesions of gastric cancer. The aim of this study was to determine the usefulness of the biomarkers pepsinogen I(PgI), pepsinogen II (PgII), gastrin-17, and H. pylori antibodies in the identification of precursor lesions. Methods: We studied 129 patients with gastric symptoms. The biomarker status was determined using GastroPanel by means of the ELISA-technique. Results: Biomarkers detected atrophy in 14% of the subjects, and 49.6% had positive antibodies for H. pylori. A PgI/PgII ratio < 3 was an important risk biomarker for precursor lesions in our population (OR = 9.171, 95% CI: 1.723-48.799, p = 0.009); however, biomarkers showed low accuracy with histopathological study. Conclusions: In the Western Mexican population, precursor lesions (AG, IM) are common in adults (45%) with dyspepsia but infrequent in children (8%). H. pylori infection was detected in 41.3% of adults and 16.0% of children. Of the studied biomarkers, a PgI/PgII ratio < 3 was an important risk factor for precursor lesions such as AG or IM in our population, with an OR of 9.171 (95% CI: 1.723-48.799, p = 0.009).
RESUMO
Background: Intestinal infectious diseases are a global concern in terms of morbidity, and they are closely linked to socioeconomic variables such as quality of life, weather and access to healthcare services. Despite progress in spatial analysis tools and geographic information systems in epidemiology, studies in Ecuador that evaluate temporal trends, specific geographic groups, and their correlation with socioeconomic variables are lacking. The absence of such information makes it challenging to formulate public health policies. This study sought to identify the spatial and temporal patterns of these diseases in Ecuador, along with their correlation with socioeconomic variables. Methods: In Ecuador, the study was carried out in a continental territory, focusing on data related to intestinal infectious diseases collected from the National Institute of Statistics and Census (Instituto Nacional de Estadística y Censos) during the period from 2014 to 2019. This study involved spatial and temporal analyses using tools such as the global Moran's index and Local Indicators of Spatial Association to identify spatial clustering patterns and autocorrelation. Additionally, correlations between morbidity rates and socioeconomic variables were examined. Results: During the investigated period, Ecuador registered 209,668 cases of these diseases. Notable variations in case numbers were identified, with a 9.2% increase in 2019 compared to the previous year. The most impacted group was children under 5 years old, and the highest rates were centered in the southern and southwestern regions of the country, with Limón Indanza and Chunchi being the cantons with the highest rates, notably showing a significant increase in Limón Indanza. Additionally, there were significant correlations between morbidity rates and socioeconomic variables, school dropout rates, low birth weight, and access to water services. Conclusion: This study emphasizes the importance of considering socioeconomic variables when addressing these diseases in Ecuador. Understanding these correlations and geospatial trends can guide the development of health policies and specific intervention programs to reduce the incidence in identified high-risk areas. More specific research is needed to understand the underlying causes of variability in morbidity and develop effective prevention strategies.

Gut fungal imbalances, particularly increased Candida spp., are linked to obesity. This study explored the potential of Lactiplantibacillus plantarum cell-free extracts (postbiotics) to modulate the growth of Candida albicans and Candida kefyr, key members of the gut mycobiota. A minimal synthetic gut model was employed to evaluate the effects of Lactiplantibacillus plantarum postbiotics on fungal growth in mono- and mixed cultures. Microreactors were employed for culturing, fungal growth was quantified using CFU counting, and regression analysis was used to evaluate the effects of postbiotics on fungal growth. Postbiotics at a concentration of 12.5% significantly reduced the growth of both Candida species. At 24 h, both C. albicans and C. kefyr in monocultures exhibited a decrease in growth of 0.11 log CFU/mL. In contrast, mixed cultures showed a more pronounced antifungal effect, with C. albicans and C. kefyr reductions of 0.62 log CFU/mL and 0.64 log CFU/mL, respectively. Regression analysis using the Gompertz model supported the antifungal activity of postbiotics and revealed species-specific differences in growth parameters. These findings suggest that L. plantarum postbiotics have the potential to modulate the gut mycobiota by reducing Candida growth, potentially offering a therapeutic approach for combating fungal overgrowth associated with obesity.

Bats are important reservoirs and spreaders of pathogens. Giardia duodenalis is a globally important protozoan that infects humans and other mammals with considerable public health burden, particularly on the child development. Based on genetic variation and host specificity, G. duodenalis is categorized into eight genotypes/assemblages A-H. Assemblages A and B are widespread globally and are associated with human and animal disease. There is evidence of Giardia in the bat feces from diverse geographic regions, but the G. duodenalis assemblages are unknown, which is a key point for the One Health view. Here, we successfully amplified the BG/GDH/DIS3/HCMP2/HCMP3 targets of G. duodenalis from five bat species captured in the Brazilian Amazon biome revealing the presence of zoonotic G. duodenalis assemblages A and B in the feces of these flying mammals. Our study reveals that bats may play a role in transmission of zoonotic G. duodenalis, at least in this biome.
RESUMO
Anemia is the most common hematological disorder affecting humans. In Peru, anemia is a pressing issue that present the most significant concern due to its adverse effects, such as delayed growth and psychomotor development, in addition to a deficiency in cognitive development. Anemia is a significant public health issue in Peru, which has one of the highest prevalence rates in infants in the Latin American and Caribbean (LAC) region, affecting approximately 43.6 % of children under three years nationally as of 2017, with rural areas experiencing a higher prevalence of approximately 53.3 %. In 2019, the prevalence was highest in the Sierra (48.8 %) and Selva regions (44.6 %), whereas the coast had a lower rate of 33.9 % in children under 36 months. Although the composition of the gut microbiota is relatively well described in children, there is little information on the identification of the microbiota in iron-deficiency anemia. There is evidence that diseases or health conditions can change the microbiota, or vice versa. This study aimed to identify the microbiota in children with anemia who did not recover after iron treatment. In a previous study, we found that the phylum Actinobacteria was predominant in the microbiota of children with anemia. These data will be useful for understanding the functionality of the most important bacteria found in each group at the genus or species level, especially the metabolic pathways in which they participate and their links with iron metabolism. Microbial composition data were obtained through next-generation 16S rRNA sequencing (NGS) of stool samples from children with anemia in southern Peru. Numerous studies have underscored the importance of early symbiotic development in infant health and its long-term impact on health. From infancy, modulation of the gut microbiota can promote long-term health. According to the National Institute of Health (NIH), iron-deficiency anemia may cause serious complications, such as fatigue, headaches, restless legs syndrome, heart problems, pregnancy complications, and developmental delays in children. The development of the gut microbiota is regulated by a complex interplay between host and environmental factors. The bidirectional link between the gut microbiota and anemia plays an important role in tracking the gut microbiota and will be useful in understanding the composition of the intestinal microbiota and its implications in anemia, which has now become a public health problem. Our previous study investigated the microbial composition in children with iron-deficiency anemia and revealed the presence of several bacterial groups, including Proteobacteria, Actinobacteria, Firmicutes, and Chloroflexi. In addition, these data may be useful for investigating the association between the intestinal microbiota of children with persistent anemia and those who have recovered.
RESUMO
Genetic variability within the same fish species could confer soybean meal (SBM) tolerance in some individuals, thus favoring growth. This study investigates the single-nucleotide polymorphisms (SNPs) in differentially expressed genes (DEGs) favoring SBM tolerance in higher-growth zebrafish (Danio rerio). In a previous work, nineteen families of zebrafish were fed a fish meal diet (100FM control diet) or SBM-based diets supplemented with saponin (50SBM + 2SPN-experimental diet), from juvenile to adult stages. Individuals were selected from families with a genotype-by-environment interaction higher (170 ± 18 mg) or lower (76 ± 10 mg) weight gain on 50SBM + 2SPN in relation to 100FM. Intestinal transcriptomic analysis using RNA-seq revealed six hundred and sixty-five differentially expressed genes in higher-growth fish fed 50SBM + 2SPN diet. In this work, using these results, 47 SNPs in DEGs were selected. These SNPs were genotyped by Sequenom in 340 zebrafish that were fed with a 50SBM + 2SPN diet or with 100FM diet. Marker-trait analysis revealed 4 SNPs associated with growth in 3 immunity-related genes (aif1l, arid3c, and cst14b.2) in response to the 50SBM + 2SPN diet (p-value < 0.05). Two SNPs belonging to aif1l y arid3c produce a positive (+19 mg) and negative (-26 mg) effect on fish growth, respectively. These SNPs can be used as markers to improve the early selection of tolerant fish to SBM diet or other plant-based diets. These genes can be used as biomarkers to identify SNPs in commercial fish, thus contributing to the aquaculture sustainability.
