Automated Spectrophotometric Assays for the Measurement of Ammonia and Bicarbonate in Saliva of Horses: Analytical Validation and Changes in Equine Gastric Ulcer Syndrome (EGUS).

Ammonia (NH3) and bicarbonate (HCO3) have been related to gastric ulcers in humans. Ammonia is considered a possible cause of gastric ulcers, whereas bicarbonate has a protective function. The presence of ulcers in the stomach of horses is defined as Equine Gastric Ulcer Syndrome (EGUS), which is a frequent disease in this species, and it has been associated with changes in saliva composition, such as in analytes related to inflammation, immune system and oxidative stress. The objectives of this study were (1) to perform an analytical validation of two automated spectrophotometric assays, one for ammonia and one for bicarbonate, in the horses' saliva and (2) to evaluate their possible variations with EGUS. Analytical validation of the automated assays for ammonia and bicarbonate in the saliva of horses showed that both assays were precise and accurate. In addition, significantly higher values of ammonia and lower values of bicarbonate were found in the saliva of horses with EGUS compared to healthy horses. It can be concluded that ammonia and bicarbonate can be measured in the saliva of horses and that ammonia increases and bicarbonate decreases in this sample type could be related to the presence of EGUS in this species.

Feeding therapy in a neurotypical child with feeding difficulties: A case report.

A feeding therapy developed in Brazil integrates aspects from diverse approaches and has increasingly been acknowledged as an adjunctive approach for addressing childhood feeding difficulties. In children, problems with eating are a common issue that affects their nutritional well-being, health, and overall quality of life, and can greatly hinder their social, emotional, and physical growth. In the realm of pediatrics, feeding therapy uses food and nutritional education, interactive games, and activities tailored to age groups and individualized treatment plans. The primary objective is to transform mealtime experiences and gradually foster children's acceptance of previously rejected foods. However, this treatment approach is new and recent in Brazil and lacks studies that explore and elucidate the topic. Therefore, this report aims to describe the follow-up and effects of feeding therapy in a 3-y and 8-mo-old neurotypical male patient with feeding difficulties who underwent feeding therapy conducted by a dietitian over a period of 19 wk. The feeding therapy consisted of 45-min sessions once a week in which food and nutrition education activities, games, and interactive activities, personalized according to the treatment plan, were carried out. The effects of feeding therapy were evaluated according to the patient's feeding progression throughout the sessions and their stepwise progress in the eating hierarchy. Based on our observations, the findings of this study suggest that feeding therapy practiced in Brazil can be a viable treatment approach for addressing feeding difficulties within this population. The feeding therapy originated in Brazil stands out from traditional nutritional care with its nurturing and compassionate approach that prioritizes respect for the child.

Association between Eosinophil Count and Cortisol Concentrations in Equids Admitted in the Emergency Unit with Abdominal Pain.

Stress leukogram includes eosinopenia as one of its main markers (neutrophilia, eosinopenia, lymphopenia, and mild monocytosis). Cortisol is the main stress biomarker, which is also strongly correlated with the severity of gastrointestinal diseases. This study aimed to determine the relationship between salivary cortisol and the eosinophil cell count (EC) in equids with abdominal pain. To do this, 39 horses with abdominal pain referred to an emergency service were included. All samples were taken on admission, and several parameters and clinical data were included. Equids were classified according to the outcome as survivors and non-survivors. Non-surviving equids presented higher salivary cortisol concentrations (Non-Survivors: 1.580 ± 0.816 µg/dL; Survivors 0.988 ± 0.653 µg/dL; p < 0.05) and lower EC (Non-Survivors: 0.0000 × 103/µL (0.000/0.0075); Survivors: 0.0450 × 103/µL (0.010/0.1825); p < 0.01). In addition, the relationship between salivary cortisol concentration, EC, and the WBC was determined. Only a strong correlation (negative) was observed between cortisol and EC (r = -0.523, p < 0.01). Since cortisol is not an analyte that can be measured routinely in clinical settings such as emergencies, the EC could be a good alternative. While the results are promising, further studies are needed before EC can be used confidently in routine practice to predict survival in cases of abdominal pain.

Family Separation at the US and Mexico Border Continues.

Record-breaking levels of asylum seeking by families with young children continue at the United States/Mexico border, particularly the Rio Grande Valley sector. In this Commentary, our aim is to increase awareness by providing child and adolescent mental health care providers with an update on current migrant conditions, bringing to light issues of family separation previously highlighted in the Journal.1 For context, our international group has collected data, via 3 large-scale studies funded by the National Institutes of Health, from more than 600 Latinx immigrants seeking asylum at the US/Mexico border in the last 4 years, during which levels of violence, climate disruption, and poverty in the Northern Triangle of Central America (ie, El Salvador, Guatemala, and Honduras) and Mexico have propelled high and sustained levels of asylum seeking in the United States. We contribute expertise in clinical psychology, Latinx psychology, attachment disruption, and public health, as well as this front-row perspective.

Resolution of two cases of ovarian abscesses in mares subjected to ovum pick up.

BACKGROUND: Currently, for in vitro embryo production in live mares, immature oocytes are retrieved by transvaginal follicular aspiration or ovum pick up (OPU). Occasionally, ovarian abscesses have been described after OPU, but no current consensus exists on how to treat this condition. OBJECTIVES: To describe diagnosis and successful treatment of ovarian abscesses in two mares subjected to OPU. STUDY DESIGN: Case report. METHODS: Case records were reviewed and summarised. RESULTS: In the first case, a pony mare showed tachypnoea, tachycardia, high temperature, leukocytosis, left hindlimb lameness and slight increase in concentration of serum amyloid A. Ultrasonography revealed an increase in the size of the left ovary and two well defined structures suggestive of ovarian abscess. A left ovariectomy by standing laparoscopy was the treatment of choice: the diagnosis was confirmed, and bacterial culture produced heavy growth of Streptococcus equi Zooepidemicus. In the second mare, an abnormal structure was observed in the left ovary in a routine transrectal ultrasonographic exam in the absence of any clinical signs or abnormal blood parameters. A medical approach was chosen and a sample of the purulent material was aspirated with a transvaginal ultrasound-guided approach. The sample yielded a heavy growth of Streptococcus equi Zooepidemicus after culture. Treatment was initiated with rifampicin and trimethoprim-sulfadiazine based on the antibiogram results and the abscess completely resolved after 40 days. MAIN LIMITATIONS: Limited to two cases. CONCLUSIONS: Ovarian abscesses in mares can be successfully treated both surgically and medically.

Mass animal sacrifice at casas del Turuñuelo (Guareña, Spain): A unique Tartessian (Iron Age) site in the southwest of the Iberian Peninsula.

Zooarchaeological analyses of the skeletal remains of 52 animals unearthed in the courtyard of an Iron Age Tartessian building known as Casas del Turuñuelo (Badajoz, Spain) shed light on a massive sacrifice forming part of a series of rituals linked to the site's last period of activity and final abandonment. The rites took place towards the end of the 5th century BCE when both the building (intentionally destroyed) and the sacrificed animals were intentionally buried under a tumulus 90 m in diameter and 6 m high. The main objective of the zooarchaeological and microstratigraphic analyses was to determine the phasing of the sacrificial depositions. Evidence gathered from taphonomic assessments and a series of radiocarbon datings indicate that the sacrifices fall into three consecutive phases spanning several years. The findings of the zooarchaeological analyses clearly point to a selection of equid and cattle males. Adult equids predominate (MNI = 41) followed by adult and sub-adult cattle (MNI = 6). Pigs, in turn, are only represented by a few adults and sub-adult females (MNI = 4). Among the animals is a single dog of undetermined sex between 3 and 4 years of age. The fact that the animals are mostly adults discards the likelihood that they died from natural causes or an epidemic. In addition, the scenographic deposition of certain equids in pairs, as well as evidence of the burning of plant offerings, suggest an intentional ritualistic sacrifice. Nine of the initial depositions of Phase 1 in the SE quadrant were scattered and certain of their bones bear marks characteristic of both prolonged open air exposure and scavengers. Another 31 animals from Phases 1 and 2 are represented by almost complete, articulated skeletons, indicating they were promptly covered. Phase 3, by contrast, reveals both almost complete and partial animals bearing clear signs of processing for human consumption. This study thus sheds light on both the sequence of the animal sacrifices and the protocols linked to rites accompanied by the celebration of banquets. Certain features associated with the sealing of this building under a tumulus offer evidence of the decline of the Tartessian Culture. This study thus advances notions serving to contextualize ritual animal sacrifices in the framework of practice observed at other Iron Age sites in the Iberian Peninsula and elsewhere throughout Europe.

Alterations in executive functions in inmates convicted for violent behavior: a systematic review.

Background: The growth of the prison population and the high recidivism rates of inmates represent a major public safety problem. Objective: This systematic review explored executive functions in inmates convicted of violent behavior compared with inmates convicted of non-violent behavior and healthy controls (HCs). Methods: Systematic searches were carried out using five databases (PubMed, Scopus, Web of Science, EBSCO, and Embase) until March 6th, 2023. Following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, two reviewers independently performed the screening, data extraction, and risk of bias assessment of the 8 studies included. The protocol of this study was registered in Prospective Register of Systematic Reviews (PROSPERO), under registration number CRD42021252043. Results: Consistently, inmates convicted of violent behavior exhibited a greater alteration in inhibition than inmates convicted of non-violent behavior (four out of four studies) and HCs (two out of two studies). In addition, inmates convicted of violent behavior showed greater impairments in cognitive flexibility (two out of three studies) and working memory (two out of three studies) than HCs. Although with limited evidence (only one study), they also showed worse performance in set shifting and planning than HCs. Conclusion: This study provides evidence of alterations in inhibition in inmates convicted of violent behavior compared to inmates convicted of non-violent behavior and HCs. Even though inmates convicted of violent behavior showed greater impairments in planning and set shifting than HCs, these findings were supported in only one study. In general, more robust evidence is needed to confirm alterations in inmates convicted due to violent behavior. These findings highlight the importance of designing and promoting specific cognitive interventions that contribute to the reintegration of inmates into society.

First data and translation of the Child Attachment Interview en Español.

The Child Attachment Interview (CAI) was designed to assess attachment representation in middle childhood-filling a gap between behavioral paradigms and adult interviews-and has demonstrated adequate psychometric properties in middle childhood and adolescence. To date, the CAI has not been available in Spanish, given the absence of an accepted translation and psychometric data. Spanish is the second most spoken language in the world, and assessment of attachment in an individual's native language is critical given differences in emotional processing, memory, and disclosure in first versus second languages. We translated the CAI (with consultation from its creator) utilizing standardized translation and back-translation procedures and examined its psychometric properties in a sample of Spanish-speaking high school students. In this study, we report on that process and data gathered from N = 94 Spanish-speaking adolescents in grades 9-12; 20% were double-coded and interrater reliability was acceptable. Findings support the single factor "Security-Dismissal" model, and relations between classifications and subscales were consistent with previous findings. Support for convergent and discriminant validity was provided for both classifications and subscales; however, concurrent validity varied across classifications and subscales. In sum, our translation demonstrates psychometric promise for the assessment of internal working models of attachment in Spanish-speaking high school students.

Changes in Calprotectin (S100A8-A9) and Aldolase in the Saliva of Horses with Equine Gastric Ulcer Syndrome.

Equine gastric ulcer syndrome (EGUS) is a highly prevalent disease that affects horses worldwide. Within EGUS, two different forms have been described: equine squamous gastric disease (ESGD) and equine glandular gastric disease (EGGD). The associated clinical signs cause detrimental activity performance, reducing the quality of life of animals. Saliva can contain biomarkers for EGUS that could be potentially used as a complementary tool for diagnosis. The objective of this work was to evaluate the measurements of calprotectin (CALP) and aldolase in the saliva of horses as potential biomarkers of EGUS. For this purpose, automated assays for the quantification of these two proteins were analytically validated and applied for detecting EGUS in a total of 131 horses divided into 5 groups: healthy horses, ESGD, EGGD, combined ESGD and EGGD, and horses with other intestinal pathologies. The assays showed good precision and accuracy in analytical validation, and they were able to discriminate between horses with EGUS and healthy horses, especially in the case of CALP, although they did not show significant differences between horses with EGUS and horses with other diseases. In conclusion, salivary CALP and aldolase can be determined in the saliva of horses and further studies are warranted to elucidate the potential of these analytes as biomarkers in EGUS.

Evaluation of a Comprehensive Profile of Salivary Analytes for the Diagnosis of the Equine Gastric Ulcer Syndrome.

In this report, the measurement of salivary biomarkers as an aid for diagnosis of equine gastric ulcer syndrome (EGUS) was studied. A comprehensive panel of 23 salivary analytes was measured in the saliva of horses affected by EGUS and compared to healthy animals and horses with other diseases clinically similar to EGUS but with a negative diagnosis at gastroscopic examination. A total of 147 horses were included in the study and divided into heathy population (n = 12), the EGUS group (n = 110), and the group of horses with other diseases (n = 25). From the 23 analytes studied, 17 showed increased values in EGUS horses when compared to healthy ones, and uric acid, triglycerides, and calcium were significantly increased in horses with EGUS compared to the group of other diseases. The receiver operating characteristic curve analyses showed a modest but significant discriminatory power of those three analytes to identify EGUS from other diseases with similar symptoms. The discriminatory power enhanced when the results of the three analytes were combined. In conclusion, the results showed that selected salivary analytes could have potential use as biomarkers in horses with EGUS.

Evaluation of Eosinopenia as a SIRS Biomarker in Critically Ill Horses.

Systemic inflammatory response syndrome (SIRS) is a very common finding in critically ill patients. To accurately identify patients with SIRS and those who need intensive care, several markers have been evaluated, including cortisol, WBC or lactate. It is widely known that a stress leukogram includes eosinopenia as one of its main markers (neutrophilia, eosinopenia, lymphopenia and mild monocytes). It is known that cortisol concentration in plasma is the main stress biomarker and is strongly correlated with the severity of disease in horses. However, it is not possible to measure this parameter routinely in clinical conditions. Hence, in this study it was hypothesized that the eosinophil count could be a reliable parameter to identify critically ill horses. Horses included in this study were divided into three groups: Group A (sick horses received at the Emergency Unit which did not fulfil the criteria for SIRS), Group B (horses that meet two or more criteria for inclusion in the definition of SIRS) and a control group of healthy horses. In this study, horses with SIRS showed lower eosinophil counts than healthy horses. Moreover, non-surviving horses exhibited lower eosinophil counts than survivors. Eosinopenia could be used to identify horses with SIRS and can be useful as a prognostic marker.

Bilateral Uveitis in a Horse With a Renal Carcinoma.

Equine uveitis is a common eye disease that affect horses from different breeds, ages, and genders. Uveitis has been described as inflammation of the uvea secondary immunomediated processes or eye trauma. Renal cell carcinoma (RCC) is the most common tumor that can affect the equine kidneys. The present case describe a horse that was referred to the Veterinary Teaching Hospital of the University of Extremadura with bilateral uveitis. The horse was treated for the primary complain but the horse collapse and die during hospitalization. At necropsy, a tumoral mass in kidney with extensive in other locations as liver, lung, and lymphonodes was described. Within peritoneal cavity a pedunculated mass has been observed next to severe hemoperitoneum. Histologically, primary neoplasia and its metastasis was composed by a proliferation of epithelial cells, which were organized in a tubulopapillary pattern, similarly in the ciliary body this pattern was also observed. The diagnosis of renal carcinoma with metastasis in both uveal structures was performed. Immunomarker with CD10, AE1-AE3, and vimentin evidenced the same origin of primary neoplasia. Uveal metastasis should be included as differential diagnoses in aged horses with uveitis that not response with the medical treatment.

A strong contender for mental health screening in Latinx immigrant youth: Psychometric properties of the Strengths and Difficulties Questionnaire.

Latinx youth seeking asylum in the U.S. experience mental health disparity due to exposure to trauma and adversity. Health systems and schools in the U.S. are unprepared to screen for psychopathology in this population, much of which is mono-lingual Spanish-speaking, due to the absence of psychometrically-vetted instruments. The Strengths and Difficulties Questionnaire (SDQ) has strong empirical support as a mental health screener in other demographics. However, there has been no psychometric research in Spanish-speaking immigrant youth and, therefore, the utility in this population remains unknown. The aims of the current study were to examine the SDQ's (a) internal structure, (b) factor structure, (c) test-retest reliability, and (d) concurrent validity. Results are based on N = 110 recently immigrated high school students (60% male, Mage = 19) who completed the SDQ in Spanish. Findings provided support for the Total Score, which displayed evidence of internal consistency, test-retest reliability, and concurrent validity with the Child Behavior Checklist. However, support for the use of the SDQ's subscale scores was limited. In sum, the SDQ Total Score holds promise as a screening instrument for recently immigrated Latinx youth in clinical, health, and educational settings, and use of the subscales requires future research and refinement.

Attachment, loss, and related challenges in migration.

Attachment theory-built on the knowledge that infants have an innate need to form an attachment bond with a caregiver and that separation from or loss of that caregiver has a lasting impact on the child's development-is a useful lens through which to examine the consequences of family separation due to migration. The aim of this review was to highlight the impacts of separation due to migration on children's attachment security and psychosocial outcomes to illustrate that family separation-regardless of whether is it "chosen" by a family who sees no other path towards safety or prosperity or inflicted by legal policies associated with immigration, detention, and deportation-negatively affects children's attachment security with serious consequences for their well-being.

Familismo neutralizes the effects of discrimination on suicide-related thoughts and behaviors in Latinx young adults.

In recent years, there has been a significant increase in rates of suicide-related thoughts and behaviors among Latinx young adults. Given Latinx young adults are one of the fastest growing subgroups in the United States, this raises significant public health concern. Perceived discrimination has consistently been identified as a risk factor and has been positively associated with depressive symptoms, further exacerbating risk for the development of suicide-related thoughts and behaviors. Critical to understanding Latinx mental health is familismo, a core cultural value that entails connectedness, dedication, commitment, and loyalty to family. Moreover, it involves seeking family for advice and support. The current study sought to examine depressive symptoms as mediator for the relation between perceived discrimination and suicide-related thoughts and behaviors while investigating familismo as a moderator in attenuating these relations within a college aged Latinx sample (N = 1037, 75.3% female, Mage = 21, SD = 4.49). Across models, depressive symptoms explained the relation between perceived discrimination and suicide-related thoughts and behaviors (p ≤0.001-0.024) with familismo significantly acting as moderator (p = .009). In exploring the protective effects of an important Latinx cultural value on a growing public health disparity, the current study provides novel insight that may be used to tailor and adapt current intervention and prevention efforts for Latinx young adults at risk for suicide-related thoughts and behaviors.

Changes in Proteins in Saliva and Serum in Equine Gastric Ulcer Syndrome Using a Proteomic Approach.

Changes in the salivary proteome in 12 horses with the two diseases included in equine gastric ulcer syndrome (EGUS), equine glandular gastric disease (EGGD) (n = 6) and equine squamous gastric disease (ESGD) (n = 6), were evaluated using a high-resolution LC-MS/MS analysis of TMT-labelled peptides and compared to 10 healthy control horses. Serum was also analysed for comparative purposes. The comparison between the horses with EGGD and controls showed significant changes in 10 salivary proteins, whereas 36 salivary proteins were differently abundant between ESGD and control groups. The most upregulated proteins in the case of EGGD were related to immune activation whereas, in horses with ESGD, the most significantly changed proteins were associated with squamous cell regulation and growth. Compared to serum, saliva showed a higher number of proteins with significant changes and a different pattern of changes. The proteins identified in our study, in addition to providing new information about the pathophysiological mechanisms in these diseases, could have the potential to be novel biomarkers for the diagnosis or monitoring of EGGD and ESGD.

Effects of Competitive ELISA-Positive Results of Piroplasmosis on the Performance of Endurance Horses.

Endurance is an increasingly popular equestrian sport. However, in southern Europe, there is a high prevalence of horses that are asymptomatic carriers of equine piroplasmosis (EP), a tick-borne disease that could affect their performance. This study aimed to evaluate the impact and influence of EP on the performance of endurance horses. Blood samples were collected from 40 horses in Extremadura, Spain, before and after a race, in different national elite horse endurance competitions. Hematological and biochemical parameters and EP seroprevalence were analysed by competitive enzyme-linked immunosorbent assay. The global seroprevalence of EP was 70%, with 27 horses testing positive for Theileria equi (67.5%) and three (7.5%) for Babesia caballi, with two of these horses (5%) positive for both. Approximately 82.5% of the horses (33 of 40) completed the competition, with no influence on performance or position achieved in those with subclinical parasitosis. There were also no significant differences in hematological or biochemical values between seropositive and seronegative horses. The data suggest that horses without clinical signs of EP can participate without performance impairment in competitions of up to 80 km. Although it is recommended that longer distance competitions should be further evaluated, this is the first step for decision-making by organizers and participants in this sport.

Changes in Oxidative Status Biomarkers in Saliva and Serum in the Equine Gastric Ulcer Syndrome and Colic of Intestinal Aetiology: A Pilot Study.

Changes in the oxidative status of the blood of horses suffering from gastric ulcers and colic of intestinal aetiology (CIE) have been reported. However, saliva can also be a source of biomarkers of oxidative status. Therefore, this study aims to validate automated assays for the measurement of oxidative status biomarkers (ferric reducing ability of saliva/serum-FRAS/FRAP, cupric reducing antioxidant capacity-CUPRAC, the Trolox equivalent antioxidant capacity-TEAC, uric acid, and advanced oxidation protein products-AOPP) in the saliva and serum of horses, to assess their changes in the different ulcer gastric diseases (squamous-ESGD and glandular-EGGD) and CIE, and to evaluate their relationship with serum amyloid A (SAA), adenosine deaminase (ADA), and the systemic inflammatory response syndrome (SIRS) status. The assays showed a low imprecision and good linearity with enough sensitivity in both fluids. In EGGD, higher levels of FRAS, uric acid, and AOPP in saliva were observed compared to the healthy group, correlating with the salivary ADA levels. Horses with CIE showed increases in uric acid concentrations in serum associated with their SIRS status and outcome of the disease. In conclusion, analytes related to the oxidative status can be measured in the saliva and serum from horses by automated assays, and some of them can potentially be assessed as biomarkers in horses with gastric ulcers and CIE.
