Estudio comparativo del dolor abdominal en las culturas maya Tzeltal, maya Tzotzil y maya Q ́eqchi ́y el uso de Ageratina ligustrina para su tratamiento / Comparative study of abdominal pain in the Mayan cultures Tzeltal, Maya Tzotzil and Maya Q ́eqchi´ and use of Ageratina ligustrina for the treatment

El presente estudio es una comparación del dolor abdominal producido por trastornos gastrointestinales, aliviado por Ageratina ligustrina , entre los grupos maya Tzeltal, Tzotzil y Q ́eqchi ́, el cual integró un enfoque etnomédico, etnobotánico y transcultural, comparando estudios previos con el presente trabajo de campo. Para evaluar la eficacia de Ageratina para aliviar el dolor abdominal, se realizó un inventario de las moléculas reportadas en esta especie, así como de su actividad farmacológica, a través de una revisión bibliográfica. Los resultados mostraron que la epidemiología del dolor producido por TGI, su etnobotánica y el modelo explicativo del dolor abdominal fueron similares entre grupos étnicos. Asimismo, se identificaron 27 moléculas con efectos antiinflamatorios y antinociceptivos, lo que podría explicar por qué esta especie es culturalmente importante para los pobladores maya Tzeltal, Tzotzil y Q ́eqch i ́ para el alivio del dolor abdominal, mientras que, desde el punto de vista biomédico, es una especie con potencial para inhibir el dolor visceral.

The current study is a comparison of the abdominal pain conception produced by gastrointestinal disorders, relieved by Ageratina ligustrina , among inhabitants of the Mayan Tzeltal, Tzotzil, and Q'eqchi' groups ethnomedical, ethnobotanical, and cross -cultural approaches were used to compare previous studies with the present field work. To evaluate the efficacy of A. ligustrina to relieve pain, also through a bibliographic review an inventory of the molecules present in this species was performed, as well as their pharmacological activity. The results showed that the epidemiology of pain produced by GID, its ethnobotany, and the explanatory model of abdominal pain are similar among ethnic groups. Likewise, 27 molecules with anti-inflammatory and anti-nociceptive effects were identified, which could explain why this species is culturally important for the Mayan Tzeltal, Tzotzil, and Q'eqchi' groups for the relief of abdominal pain, while, from a biomedical point of view, it is a species with potential to inhibit visceral pain.

The Use of Diets in the Diagnosis and Treatment of Common Gastrointestinal Diseases in Dogs and Cats.

The nutritional health of dogs and cats is important to pet owners around the world. Nutrition is inextricably linked to the health of the gastrointestinal system and vice versa. Gastrointestinal signs, such as vomiting, diarrhea, anorexia, or weight loss, are one of the most common reasons that dog and cat owners make non-routine appointments with veterinarians. Those patients are evaluated systematically to identify and/or rule out the causes of the symptoms. Some causes of chronic diarrhea are within the gastrointestinal tract while others are secondary to pathogenic factors outside the digestive system. Some useful biomarkers of chronic intestinal disease (enteropathy) exist in serum and feces. After determination that the clinical signs are due to primary gastrointestinal disease and that there is no parasitism, specific diets are used for at least two weeks. There are several types of diets for pets with chronic enteropathies. There are limited ingredient diets and hydrolyzed protein diets with reduced levels of allergens. There are also highly digestible and fiber-enhanced diets. Some diets contain probiotics and/or prebiotics. If symptoms do not improve and the patient is stable, a diet from a different class may be tried. For chronic enteropathies, the prognosis is generally good for symptom resolution or at least improvement. However, if interventions with novel diets do not ameliorate the symptoms of chronic enteropathy, then antibiotic, anti-inflammatory, or immunosuppressant therapy or further, more invasive diagnostics such as taking an intestinal biopsy, may be indicated. Pancreatitis is a common gastrointestinal disease in dogs and cats and patients may present with mild to severe disease. Many patients with mild to moderate disease can be successfully treated with early supportive care, including feeding a low-fat diet. A novel pharmaceutical, fuzapladib (Panoquell-CA1) looks very promising for treating more severe forms of acute pancreatitis in dogs. Maintenance on a low-fat diet may prevent pancreatitis in at-risk dogs. Future advances in medicine will allow pet owners and veterinarians to use dietary management to maximize the health of their dogs and cats.

In silico design of a novel multi-epitope vaccine against HCV infection through immunoinformatics approaches.

Infection with the hepatitis C virus (HCV) is one of the causes of liver cancer, which is the world's sixth most prevalent and third most lethal cancer. The current treatments do not prevent reinfection; because they are expensive, their usage is limited to developed nations. Therefore, a prophylactic vaccine is essential to control this virus. Hence, in this study, an immunoinformatics method was applied to design a multi-epitope vaccine against HCV. The best B- and T-cell epitopes from conserved regions of the E2 protein of seven HCV genotypes were joined with the appropriate linkers to design a multi-epitope vaccine. In addition, cholera enterotoxin subunit B (CtxB) was included as an adjuvant in the vaccine construct. This study is the first to present this epitopes-adjuvant combination. The vaccine had acceptable physicochemical characteristics. The vaccine's 3D structure was predicted and validated. The vaccine's binding stability with Toll-like receptor 2 (TLR2) and TLR4 was confirmed using molecular docking and molecular dynamics (MD) simulation. The immune simulation revealed the vaccine's efficacy by increasing the population of B and T cells in response to vaccination. In silico expression in Escherichia coli (E. coli) was also successful.

A Review of Traditional Use, Constituent Analysis, Bioactivity, and Application of Volatile Oils from Elsholtzia.

BACKGROUND: Elsholtzia belongs to the Labiatae family, which consists of herbaceous subshrubs and shrubs. Among them, volatile oils are an important chemical component in Elsholtzia, which have various bioactive medicinal and developmental values. METHODS: The references about volatile oils of Elsholtzia in this review were obtained from Web of Science, SciFinder, PubMed, Willy, Elsevier, SpringLink, ACS publications, Google Scholar, Baidu Scholar, Scopus, and CNKI. The other information about Elsholtzia was obtained from classical works or ancient books. RESULTS: Traditionally, the volatile oils from Elsholtzia were used in Chinese medicine to treat cholera, abdominal pain, vomiting, and scattered edema. Relevant research revealed that Elsholtzia contains many different types of volatile oils, and most of them display bioactivities, including anti-oxidant, anti-bacterial, anti-viral, hypolipidemic, insecticidal, and antiinflammatory activities, treating spleen and stomach. Furthermore, the applications of volatile oils were summarized and analyzed in this paper. CONCLUSION: The contents of traditional use, constituent analysis, bioactivity, and application of volatile oils from Elsholtzia were reviewed in this paper. This will provide important research value and a scientific basis for the in-depth study of the plants of Elsholtzia in the future.

Fuzzy recognition by the prokaryotic transcription factor HigA2 from Vibrio cholerae.

Disordered protein sequences can exhibit different binding modes, ranging from well-ordered folding-upon-binding to highly dynamic fuzzy binding. The primary function of the intrinsically disordered region of the antitoxin HigA2 from Vibrio cholerae is to neutralize HigB2 toxin through ultra-high-affinity folding-upon-binding interaction. Here, we show that the same intrinsically disordered region can also mediate fuzzy interactions with its operator DNA and, through interplay with the folded helix-turn-helix domain, regulates transcription from the higBA2 operon. NMR, SAXS, ITC and in vivo experiments converge towards a consistent picture where a specific set of residues in the intrinsically disordered region mediate electrostatic and hydrophobic interactions while "hovering" over the DNA operator. Sensitivity of the intrinsically disordered region to scrambling the sequence, position-specific contacts and absence of redundant, multivalent interactions, point towards a more specific type of fuzzy binding. Our work demonstrates how a bacterial regulator achieves dual functionality by utilizing two distinct interaction modes within the same disordered sequence.

An MR-based brain template and atlas for optical projection tomography and light sheet fluorescence microscopy in neuroscience.

Introduction: Optical Projection Tomography (OPT) and light sheet fluorescence microscopy (LSFM) are high resolution optical imaging techniques, ideally suited for ex vivo 3D whole mouse brain imaging. Although they exhibit high specificity for their targets, the anatomical detail provided by tissue autofluorescence remains limited. Methods: T1-weighted images were acquired from 19 BABB or DBE cleared brains to create an MR template using serial longitudinal registration. Afterwards, fluorescent OPT and LSFM images were coregistered/normalized to the MR template to create fusion images. Results: Volumetric calculations revealed a significant difference between BABB and DBE cleared brains, leading to develop two optimized templates, with associated tissue priors and brain atlas, for BABB (OCUM) and DBE (iOCUM). By creating fusion images, we identified virus infected brain regions, mapped dopamine transporter and translocator protein expression, and traced innervation from the eye along the optic tract to the thalamus and superior colliculus using cholera toxin B. Fusion images allowed for precise anatomical identification of fluorescent signal in the detailed anatomical context provided by MR. Discussion: The possibility to anatomically map fluorescent signals on magnetic resonance (MR) images, widely used in clinical and preclinical neuroscience, would greatly benefit applications of optical imaging of mouse brain. These specific MR templates for cleared brains enable a broad range of neuroscientific applications integrating 3D optical brain imaging.

The gastrointestinal microbiota in the development of ME/CFS: a critical view and potential perspectives.

Like other infections, a SARS-CoV-2 infection can also trigger Post-Acute Infection Syndromes (PAIS), which often progress into myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). ME/CFS, characterized by post-exercise malaise (PEM), is a severe multisystemic disease for which specific diagnostic markers or therapeutic concepts have not been established. Despite numerous indications of post-infectious neurological, immunological, endocrinal, and metabolic deviations, the exact causes and pathophysiology remain unclear. To date, there is a paucity of data, that changes in the composition and function of the gastrointestinal microbiota have emerged as a potential influencing variable associated with immunological and inflammatory pathways, shifts in ME/CFS. It is postulated that this dysbiosis may lead to intestinal barrier dysfunction, translocation of microbial components with increased oxidative stress, and the development or progression of ME/CFS. In this review, we detailed discuss the findings regarding alterations in the gastrointestinal microbiota and its microbial mediators in ME/CFS. When viewed critically, there is currently no evidence indicating causality between changes in the microbiota and the development of ME/CFS. Most studies describe associations within poorly defined patient populations, often combining various clinical presentations, such as irritable bowel syndrome and fatigue associated with ME/CFS. Nevertheless, drawing on analogies with other gastrointestinal diseases, there is potential to develop strategies aimed at modulating the gut microbiota and/or its metabolites as potential treatments for ME/CFS and other PAIS. These strategies should be further investigated in clinical trials.

Molecular identification of Proteus mirabilis, Vibrio species leading to CRISPR-Cas9 modification of tcpA and UreC genes causing cholera and UTI.

Heavy metal accumulation increases rapidly in the environment due to anthropogenic activities and industrialization. The leather and surgical industry produces many contaminants containing heavy metals. Cadmium, a prominent contaminant, is linked to severe health risks, notably kidney and liver damage, especially among individuals exposed to contaminated wastewater. This study aims to leverage the natural cadmium resistance mechanisms in bacteria for bioaccumulation purposes. The industrial wastewater samples, characterized by an alarming cadmium concentration of 29.6 ppm, 52 ppm, and 76.4 ppm-far exceeding the recommended limit of 0.003 ppm-were subjected to screening for cadmium-resistant bacteria using cadmium-supplemented media with CdCl2. 16S rRNA characterization identified Vibrio cholerae and Proteus mirabilis as cadmium-resistant bacteria in the collected samples. Subsequently, the cadmium resistance-associated cadA gene was successfully amplified in Vibrio species and Proteus mirabilis, revealing a product size of 623 bp. Further analysis of the identified bacteria included the examination of virulent genes, specifically the tcpA gene (472 bp) associated with cholera and the UreC gene (317 bp) linked to urinary tract infections. To enhance the bioaccumulation of cadmium, the study proposes the potential suppression of virulent gene expression through in-silico gene-editing tools such as CRISPR-Cas9. A total of 27 gRNAs were generated for UreC, with five selected for expression. Similarly, 42 gRNA sequences were generated for tcpA, with eight chosen for expression analysis. The selected gRNAs were integrated into the lentiCRISPR v2 expression vector. This strategic approach aims to facilitate precise gene editing of disease-causing genes (tcpA and UreC) within the bacterial genome. In conclusion, this study underscores the potential utility of Vibrio species and Proteus mirabilis as effective candidates for the removal of cadmium from industrial wastewater, offering insights for future environmental remediation strategies.

Advancing Gastrointestinal Health: Curcumin's Efficacy and Nanopreparations.

Curcumin (CCM) is a polyphenol compound extracted from the turmeric rhizome. It has various biological activities, including antibacterial, anti-inflammatory, anti-cancer, and antioxidant. Due to its diverse activities, it is often used by researchers to study the therapeutic effects on various diseases. However, its poor solubility leads to poor bioavailability, and it is necessary to increase the water solubility with the help of carriers to improve the therapeutic effect. Gastrointestinal disease is a major global health problem that continues to affect human health. In this review, we have summarized the possible mechanism and therapeutic effect of CCM in various gastrointestinal diseases, and the improvement in the curative effect of CCM with nanopreparation. Finally, we concluded that there have been many clinical trials of CCM in combination with other drugs for the treatment of gastrointestinal disease, but so far, few have used CCM nanomaterials for treatment. Although in vitro and preclinical experiments have shown that nanopreparations can improve the efficacy of CCM, there are still insufficient studies on the safety of carriers.

Lessons learned from contamination with endotoxin originated from the supplement in the cell culture medium.

Introduction: Endotoxin is a typical pyrogen derived from the outer membrane of Gram-negative bacteria. In fabricating cell-based medicinal products, it is necessary to control endotoxin in the process and the products. In the quality control tests of our clinical study, endotoxin concentration in the culture supernatant of autologous oral mucosal epithelial cell sheets exceeded the criterion value. Therefore, endotoxin measurements were conducted to clarify the cause of the endotoxin contamination. Methods: The reagents used to prepare the culture medium, the unused culture medium, and the culture supernatants were diluted with pure water. Endotoxin concentrations in the diluted samples were measured. Results: Endotoxin was detected in both the unused culture medium and the culture supernatant of the epithelial cell sheets at higher concentrations than the criterion value. Therefore, endotoxin concentrations in the reagents used to prepare the culture medium were measured and were found to be below the criterion value, except for cholera toxin. On the other hand, three lots of cholera toxin products were used for the measurement, and the endotoxin concentrations were higher than the criterion value. The results indicate that the endotoxin contamination is caused by the cholera toxin product. Conclusions: To prevent endotoxin contamination in cell-based medicinal products, endotoxin concentrations in reagents used for the fabrication should be measured in the facility conducting clinical research or confirmed by an adequate certificate of analysis from the manufacturers of the reagents.

New Vibrio cholerae sequences from Eastern and Southern Africa alter our understanding of regional cholera transmission.

Despite ongoing containment and vaccination efforts, cholera remains prevalent in many countries in sub-Saharan Africa. Part of the difficulty in containing cholera comes from our lack of understanding of how it circulates throughout the region. To better characterize regional transmission, we generated and analyzed 118 Vibrio cholerae genomes collected between 2007-2019 from five different countries in Southern and Eastern Africa. We showed that V. cholerae sequencing can be successful from a variety of sample types and filled in spatial and temporal gaps in our understanding of circulating lineages, including providing some of the first sequences from the 2018-2019 outbreaks in Uganda, Kenya, Tanzania, Zambia, and Malawi. Our results present a complex picture of cholera transmission in the region, with multiple lineages found to be co-circulating within several countries. We also find evidence that previously identified sporadic cases may be from larger, undersampled outbreaks, highlighting the need for careful examination of sampling biases and underscoring the need for continued and expanded cholera surveillance across the African continent.

Impact of large scale, multicomponent intervention to reduce proton pump inhibitor overuse in integrated healthcare system: difference-in-difference study.

OBJECTIVE: To determine how a large scale, multicomponent, pharmacy based intervention to reduce proton pump inhibitor (PPI) overuse affected prescribing patterns, healthcare utilization, and clinical outcomes. DESIGN: Difference-in-difference study. SETTING: US Veterans Affairs Healthcare System, in which one regional network implemented the overuse intervention and all 17 others served as controls. PARTICIPANTS: All individuals receiving primary care from 2009 to 2019. INTERVENTION: Limits on PPI refills for patients without a documented indication for long term use, voiding of PPI prescriptions not recently filled, facilitated electronic prescribing of H2 receptor antagonists, and education for patients and clinicians. MAIN OUTCOME MEASURES: The primary outcome was the percentage of patients who filled a PPI prescription per 6 months. Secondary outcomes included percentage of days PPI gastroprotection was prescribed in patients at high risk for upper gastrointestinal bleeding, percentage of patients who filled either a PPI or H2 receptor antagonist prescription, hospital admission for acid peptic disease in older adults appropriate for PPI gastroprotection, primary care visits for an upper gastrointestinal diagnosis, upper endoscopies, and PPI associated clinical conditions. RESULTS: The number of patients analyzed per interval ranged from 192 607 to 250 349 in intervention sites and from 3 775 953 to 4 360 868 in control sites, with 26% of patients receiving PPIs before the intervention. The intervention was associated with an absolute reduction of 7.3% (95% confidence interval -7.6% to -7.0%) in patients who filled PPI prescriptions, an absolute reduction of 11.3% (-12.0% to -10.5%) in PPI use among patients appropriate for gastroprotection, and an absolute reduction of 5.72% (-6.08% to -5.36%) in patients who filled a PPI or H2 receptor antagonist prescription. No increases were seen in primary care visits for upper gastrointestinal diagnoses, upper endoscopies, or hospital admissions for acid peptic disease in older patients appropriate for gastroprotection. No clinically significant changes were seen in any PPI associated clinical conditions. CONCLUSIONS: The multicomponent intervention was associated with reduced PPI use overall but also in patients appropriate for gastroprotection, with minimal evidence of either clinical benefits or harms.

Spatiotemporal dynamics of cholera epidemics in Ethiopia: 2015-2021.

Since the onset of the seventh cholera pandemic, Ethiopia has been affected by recurrent epidemics. However, the epidemiology of cholera in this country remains poorly understood. This study aimed to describe cholera outbreak characteristics in Ethiopia from 2015 to 2021. During this period, Ethiopia experienced four epidemic waves. The first wave involved nationwide outbreaks during the second half of 2016 followed by outbreaks predominantly affecting Somali Region in 2017. The second wave primarily affected Tigray and Afar Regions. During the third wave, multiple smaller-scale outbreaks occurred during 2019. The fourth wave was limited to Bale Zone (Oromia Region) in 2021. Overall, a north to south shift was observed over the course of the study period. Major cholera transmission factors included limited access to safe water and sanitation facilities. Severe weather events (drought and flooding) appear to aggravate cholera diffusion. Cholera transmission between Ethiopia and nearby countries (Kenya and Somalia), likely plays a major role in regional cholera dynamics. Overall, this study provides the first understanding of recent spatiotemporal cholera dynamics in Ethiopia to inform cholera control and elimination strategies.

Comparison of analysis methods to classify cholera hotspots in Ethiopia from 2015 to 2021.

Cholera continues to represent a major public health concern in Ethiopia. The country has developed a Multi-sectoral National Cholera Elimination Plan in 2022, which targets prevention and control interventions in cholera hotspots. Multiple methods to classify cholera hotspots have been used in several countries. Since 2014, a classification method developed by United Nations Children's Fund has been applied to guide water, sanitation and hygiene interventions throughout Sub-Saharan Africa based on three outbreak parameters: frequency, duration and standardized attack rate. In 2019, the Global Task Force on Cholera Control (GTFCC) proposed a method based on two parameters: average annual cholera incidence and persistence. In 2023, an updated GTFCC method for multisectoral interventions considers three epidemiological indicators (cumulative incidence, cumulative mortality and persistence,) and a cholera-case confirmation indicator. The current study aimed to classify cholera hotspots in Ethiopia at the woreda level (equivalent to district level) applying the three methods and comparing the results to optimize the hotspot targeting strategy. From 2015 to 2021, cholera hotspots were located along major routes between Addis Ababa and woredas adjacent to the Kenya and Somalia borders, throughout Tigray Region, around Lake Tana, and in Afar Region. The multi-method comparison enables decision makers to prioritize interventions according to a sub-classification of the highest-priority areas.

Assessment of Knowledge of Communicable Diseases Among Medical Students at Al-Balqa Applied University.

INTRODUCTION: Medical education is the foundation of knowledge among medical students. This study aims to investigate the knowledge of medical students at Al-Balqa Applied University, exploring their awareness of five communicable diseases, namely, leishmaniasis, hepatitis B, tuberculosis, measles, and cholera. METHODS: This cross-sectional survey included 271 participants who answered a structured validated questionnaire with varying questions on causes, symptoms, complications, transmission routes, and preventive measures for each disease. RESULTS: Knowledge of all five communicable diseases was low. Leishmaniasis knowledge was notably low (mean=6.07, SD=1.43), with participants grappling with misconceptions about transmission modes, symptoms, and preventability. Hepatitis B knowledge was also low (mean=10.46, SD=1.67), especially regarding transmission modes, revealing that 76% of students were unaware of how the virus spreads. Tuberculosis knowledge unveiled gaps (mean=7.007, SD=1.90), particularly in recognizing the causes, symptoms, and transmission routes. Measles knowledge (mean=9.56, SD=1.92) indicated a robust understanding of symptoms but unveiled misconceptions about complications and transmission routes. For cholera (mean=14.50, SD=1.98), a knowledge of symptoms was demonstrated, but confusion about causative agents, transmission routes, and preventive measures was highlighted. CONCLUSION: The findings of the study emphasize the critical need for enhanced educational strategies including curriculum revisions, increased practical exposure, engaging awareness campaigns, and the integration of interactive learning methods to increase knowledge about communicable diseases.

[Gastrointestinal symptoms and problems in children cared by pediatric palliative care teams. Observational study]. / Síntomas y problemas gastrointestinales en niños asistidos por equipos de cuidados paliativos pediátricos. Estudio observacional.

Gastrointestinal symptoms and problems (GI- SP) frequently cause discomfort and suffering in pediatric patients with life-threatening and/or life-limiting illnesses (LTI/LLI). Pediatric palliative care (PPC) professionals should be aware of them and perform a comprehensive approach. OBJECTIVE: To determine the prevalence of GI- SP in patients treated in PPC units and to describe the pharmacological and non-pharmacological measures prescribed. PATIENTS AND METHOD: Observational, prospective, multicenter, prospective study in patients with LTI/LLI, seen by PPC teams in Uruguay. The variables analyzed included age, sex, origin, type of LTI/LLI, presence of mucositis, vomiting, swallowing disorders, abdominal pain, constipation, diarrhea, digestive bleeding, problems with digestive prosthesis, and prescribed pharmacological and non-pharmacological treatment. RESULTS: 10 out of 16 PPC teams participated. 96 out of 436 patients seen presented GI- SP (22%). Median age was 4.2 years (1 month-18 years). LTI/LLI: 65% neurological and 7% oncological. The 96 patients had 114 consultations; 50% had 2 or more GI- SP per consultation. GI- SP observed: swallowing disorders (57%), constipation (53%), nausea and/or vomiting (24%), gastrostomy problems (17%), abdominal pain (10%), digestive bleeding (3%), and diarrhea (2%). There were variable prescriptions of pharmacological and non-pharmacological measures; only 50% of those with swallowing disorder received speech and hearing therapy. CONCLUSIONS: GI- SP motivated consultations in all PPC settings, frequently due to 2 or more GI- SP. Swallowing disorders and gastrostomy complications are frequent but not very visible problems in PPC. According to the comprehensive approach, pharmacological and non-pharmacological measures were implemented.
