Un análisis integrado entre la calidad de vida y las necesidades de apoyo de personas adultas con discapacidad intelectual en Chile / An integrated analysis between the quality of life and the support needs of adults with intellectual disabilities in Chile

El paradigma de apoyos y el de calidad de vida se han transformado en guías fundamentales para los avances en el ámbito de la discapacidad intelectual (DI). Con base en una muestra de 93 personas adultas con DI, se analiza, desde un enfoque cuantitativo no experimental, la relación entre la calidad de vida y las necesidades de apoyo, aplicando la escala INICO-FEAPS y la escala de Intensidad de Apoyos (SIS) para cada constructo. Los principales resultados evidencian que existe una relación fuerte e indirecta entre calidad de vida y necesidades de apoyos, y también la relevancia de analizar dichos resultados desde variables como grado de discapacidad, sexo o nivel socioeconómico. La discusión permite inferir la necesidad de discutir nuevas estrategias en torno a categorías como el grado de discapacidad, la autodeterminación e inclusión social, como elementos facilitadores de la calidad de vida y apoyos desde un enfoque integral que contribuya al desarrollo de estrategias de programas sociales para la población con DI.

The support paradigm and the quality of life paradigm have become fundamental guides for progress in the field of Intellectual Disability (ID). Based on a sample of 93 adults with ID, the relationship between Quality of Life and Support Needs is analyzed from a non-experimental quantitative approach, applying the INICO-FEAPS scale and the SIS Support Intensity scale for each construct. The main results show that there is a strong and indirect relationship between quality of life and support needs, and the relevance of analyzing these results from variables such as the degree of disability, sex or socioeconomic level. The discussion allows us to infer the need to discuss new strategies around categories such as the degree of disability, self-determination and social inclusion, as facilitating elements of quality of life and supporting a comprehensive approach that contributes to the development of social program strategies for the population with ID.

Development of an indirect ELISA for the serologic detection of bovine viral diarrhea virus based on E2 antigen sub-genotypes 1b, 1e, and 1d.

Bovine viral diarrhea virus (BVDV) causes ongoing economic losses to cattle industries, directly through reduced herd performance or indirectly through control program costs. ELISA assays, one of the most widely used techniques due to their ease of implementation, have been a valuable tool for mass surveillance and detection of BVDV. In this study, we developed a new indirect ELISA (rE2-ELISA) for serologic detection of BVDV. The assay considers three recombinant E2 protein subtypes as antigens, allowing serologic diagnosis of BVDV-1b (high prevalence worldwide), BVDV-1d and 1e (high prevalence in southern Chile) sub-genotypes. Recombinant E2 (rE2) proteins were successfully expressed in stably transfected CHO cells. Conditions for rE2 ELISAs were established after determining appropriate concentrations of antigen, blocking agent, secondary antibody, and serum dilutions to achieve maximum discrimination between positive and negative serum samples. The developed rE2-ELISA showed a sensitivity of 92.86% and a specificity of 98.33%. Clinical testing of 180 serum samples from herds in southern Chile showed high accuracy (kappa > 0.8) compared to the commercial BVDV Total Ab kit (IDEXX), with 95.37% positive and 87.5% negative predictive value. In addition, the rE2 ELISA has shown the capability to detect anti-BVDV antibodies from naturally infected animals with sub-genotypes 1b, 1e, or undetermined. These results indicate that the developed indirect ELISA could serve as a valid, and efficient alternative for identifying BVDV-infected animals, thus contributing to the success of disease control and eradication programs.

[Comorbidity of obesity and smoking and their association with cardiometabolic risk factors: Results from the 2016-2017 National Health Survey]. / Comorbilidad entre obesidad y tabaquismo, y su asociación con factores de riesgo cardiometabólicos: Resultados de la Encuesta Nacional de Salud 2016-2017.

BACKGROUND: The comorbidity between obesity and smoking and its association with cardiometabolic risk factors has been little explored. OBJECTIVES: Describe the prevalence of such comorbidity and to explore its association with cardiometabolic risk factors. METHODS: The study was based on the 2016-2017 Chilean National Health Survey and included 6,233 participants. The independent variables were general obesity according to Body Mass Index (BMI), central obesity measured by Waist-to-Height Ratio (WTHR) and Waist Circumference (WC), and daily tobacco consumption (DTC). The dependent variables were blood lipids, fasting glucose and blood pressure. The association analysis was performed by multivariate logistic regression and excluded subjects with a medical record of hypertension, diabetes mellitus and dyslipidemia to avoid reverse causality. RESULTS: The prevalence of General obesity-DTC comorbidity was 7.7%, WTHR risk-DTC was 10.8% and elevated WC-DTC was 13.2%. A total of 3,132 participants were included in logistic regressions. General obesity alone, and DTC-general obesity comorbidity had statistically significant association with elevated triglycerides, decreased HDL, elevated non-HDL and total cholesterol, elevated fasting glucose, and elevated blood pressure. The comorbidities DTC-risk WTHR and DTC-increased WC were associated with increased triglycerides and non-HDL cholesterol. DTC alone was associated with elevated systolic blood pressure. CONCLUSION: DTC-general obesity comorbidity is more frequently associated with the cardiometabolic risk factors explored than DTC-central obesity comorbidity. Smoking cessation can be a cost-effective intervention in this risk comorbidity.

[Portal vein embolization prior to major hepatectomy: A multidisciplinary approach for advanced liver tumors in Chile]. / Embolización portal previo a hepatectomía mayor: Experiencia multidisciplinaria en tumores hepáticos avanzados en Chile.

BACKGROUND: One of the main limitations to achieving a complete tumor resection in patients with technically resectable liver tumors is the presence of a small future liver remnant (FLR). Portal vein embolization (PVE) allows hypertrophy of the non-embolized lobe, reducing the risk of postoperative liver failure. AIM: To describe the experience of portal embolization prior to hepatectomy and its effectiveness in converting advanced unresectable liver tumors into resectable tumors. METHODS: Non-concurrent cohort study. All patients who underwent PVE before hepatectomy between 2016 and 2020 in our center were included. Demographic and diagnostic variables, pre and post-PVE volumes, perioperative variables, and global and disease-free survival were analyzed. RESULTS: Nineteen patients were included. Median age 66 (54-72) years and 57.9% (n= 11) were women. Bilateral metastases were present in 78.9% (n= 15). Sixteen patients (84.2%) received neoadjuvant chemotherapy. One patient (5.3%) had a complication after PVE. The median time between embolization and volumetry was 5.3 weeks (4.7-7.1). Median FLR before and after PVE were 19.8% (16.2-27.7) and 30% (25.2-40.5), respectively. The median percentage of hypertrophy was 48% (40.4-76.5). Fifteen patients (78.9%) underwent hepatectomy. Significant complications occurred in 26.6% (n= 4); among them, three patients (20%) presented postoperative liver failure. CONCLUSIONS: PVE is safe and effective in promoting FLR hypertrophy in the presence of chemotherapy, allowing patients with advanced liver tumors to undergo surgery with curative intent.

[Dying during the pandemic: Experiences of relatives of patients who died during the COVID-19 pandemic in Chile]. / Morir en pandemia: Experiencias de familiares de pacientes fallecidos durante la pandemia COVID-19 en Chile.

INTRODUCTION: The COVID-19 pandemic marked a milestone in the history of medicine worldwide. Together with the humanitarian drama it represented, the problems that arose are promoting lines of research in multiple fields. One of these fields is the aspects related to medical communication and end-of-life care. This paper reports the experiences and perceptions of relatives of patients who died during the pandemic with a psychospiritual support intervention in a public hospital in the Metropolitan Region, Chile, called "farewell". METHODS: A qualitative study was conducted with a phenomenological approach based on in-depth interviews. From this, categories were derived that allowed a systematization of the observation of the experiences. RESULTS: Among the results, the impact of the circumstances and the communication provided by the medical team on grief should be highlighted. The use of the word "farewell" emerges as a useful, albeit ambiguous, communicative tool when it comes to adequately framing an end-of-life process. CONCLUSIONS: It is argued that the end of life is an area that requires physical and psychospiritual spaces, and adequate training at all levels to do justice to a highly relevant moment in the care of people.

[Association between pain and depression in chilean older adults. Reality that requires an immediate approach]. / Asociación entre dolor y depresión en adultos mayores chilenos. Realidad que requiere abordaje inmediato.

ABASTRACT Background: To study the association between pain and depression, its characteristics and related factors in chilean older adults. METHODS: Cross-sectional analytical study of the National Survey of Dependence in Chilean older adults 2009, with a sample of 4766 people aged 60 years and older. Pain was described using a Likert scale from "no pain" to "very much pain". Depression was measured using the GDS-15 scale. Adjusted logistic regression analyses were performed to identify the association between pain and depression. RESULTS: 70% of the sample reported pain, 21.6% of high intensity. The screening was positive for depression in 23% of the sample, and 5% suspected severe depression. Both conditions were more frequent in women, subjects with low levels of schooling and rural residence. There was an association between pain and depression OR 3.46. The greater the intensity of pain, the greater the association OR 5.2 (95% CI 4.1-6.7) for depressive symptoms and OR 13.9 for suspected severe depression (95% CI 8.1-23.9). CONCLUSION: The association between pain and depression is high and is related to pain intensity, being higher in people with less education and physical dependency. The high frequency of both conditions in Chilean elderly people and their serious consequences make it an urgent public health problem, aggravated as a consequence of the prolonged isolation due to the COVID-19 pandemic.

[Intercultural characterization of the empathetic physician: Experiences of chronic patients of the chilean public health system]. / Caracterización intercultural del médico empático: Experiencias de pacientes crónicos del sistema público de salud chileno.

BACKGROUND: Empathy is a fundamental element of the physician-patient relationship for treatment and therapeutic adherence that has had to face significant changes due to the migrations of the health system in Chile. AIM: Characterize the empathetic physicians according to the perceptions of chronic patients during the encounter with national and foreign doctors in the public health system in the Maule Region. METHODS: Qualitative study of exploratory-descriptive type. Twenty chronic patients from public health services in the Maule region were interviewed remotely using the free listing technique. A thematic processual qualitative analysis of the content and a descriptive quantitative analysis were carried out where the frequency and salience of the Smith index assisted by the Anthropac 4.98 software were obtained. RESULTS: Seven categories of empathetic care were identified in the physicians-patient relationship: Affectivity (37%), Communication (19%), Attention (13%), Respect (12%), Research (9%), Knowledge (5%) and Efficiency (5%). CONCLUSIONS: The affective and psychoemotional aspects were more valued than the cognitive aspects of empathetic care. No differences were observed in assessing the empathetic care of patients seen by Chilean physicians and those treated by foreign physicians.

[Quaternary prevention in the Cardiovascular Health Program Rational use of complementary exams: A narrative review]. / Prevención cuaternaria en el programa de Salud Cardiovascular Uso racional de exámenes complementarios: Una revisión narrativa "Exámenes en prevención cardiovascular cuaternaria".

INTRODUCTION: The Cardiovascular Health Program (PSCV), founded by the Ministry of Health of Chile (Minsal), is focused on the global cardiovascular risk of people with the purpose of preventing and reducing morbidity, disability and premature death caused by cardiovascular diseases, in congruence with its sanitary aims. Quaternary Prevention is defined as "actions taken to protect individuals from medical interventions that are likely to cause more harm than good". The PSVC's 2017 technical guidelines establish a battery of 11 complementary exams to request upon entering the program, however, neither the scientific evidence that supports them nor the periodicity of their request was mentioned. The aim of this revision is to evaluate the rationality of exams request, based on updated evidence, as a strategy for quaternary prevention and potential economic savings for the sanitary system. METHODS: A narrative review was conducted through searches on databases, updated clinical guidelines and international recommendations about 11 complementary exams on the follow-up of Type 2 Diabetes and Hypertension. RESULTS: Based on the data analysis, recommendations were made according to the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. CONCLUSION: It was concluded that the costs of widely requested complementary exams could be reduced through a more efficient management guided by updated evidence. Our proposal entails changes in some processes and in the evaluation of fulfillment of the PSCV, as well as a deeper cost-effectiveness analysis of the recommendations in order to optimize the management of resources in primary health care.

[Prevalence of metabolic syndrome in adult patients with obstructive sleep apnea syndrome]. / Prevalencia de síndrome metabólico en pacientes adultos con síndrome de apneas obstructivas del sueño.

Obstructive sleep apnea syndrome (OSAS) is associated with cardiovascular risk factors that comprise metabolic syndrome, including central obesity, hypertension, insulin resistance, impaired glucose tolerance, and dyslipidaemia. AIM: To assess metabolic syndrome prevalence in adult patients with OSAS. METHODS: We administered a standardized clinical questionnaire and four sleep questionnaires (Berlin, Epworth Sleepiness Scale, STOP, and STOP-Bang), and measured anthropometric variables. We also measured serum glucose and lipids, and blood pressure following an overnight fast. Metabolic syndrome was diagnosed according to National Cholesterol Education Program criteria. Patients underwent an overnight ambulatory respiratory polygraphy to confirm the diagnosis of OSAS. The predictive variables were subjected to univariate and multivariate analysis in a logistic regression model. RESULTS: Of 1,030 screened patients, 68% were male, 92% had comorbidities and 58% had moderate-severe OSAS. Subjects with OSAS were more obese, had higher cervical and waist circumference, blood pressure and fasting serum glucose, had lower HDL cholesterol, and an increased incidence of metabolic syndrome (55.4% vs. 44.8%, p<0.013). Age, male sex, hypertension, body mass index, cervical, waist and hip circumferences, intense snoring, witnessed apnea, nocturia, and components of metabolic syndrome were associated with the risk of OSAS and its severity. Fasting blood glucose, blood pressure, and waist circumference were associated with the risk of moderate or severe OSAS, which was not significant for the alteration of blood lipids. CONCLUSION: Patients with OSAS have a high prevalence of metabolic syndrome. OSAS was associated with an increase in the cardiovascular risk factors that comprise the metabolic syndrome.

[Perceptions and experiences of users who received outpatient COVID-19 care in Santiago, Chile]. / Percepciones y experiencias de usuarios que recibieron cuidados ambulatorios de COVID-19 en Santiago de Chile.

AIM: To explore the perceptions and experiences of COVID-19 patients who received outpatient treatment in public health services in the Metropolitan Region of Chile. METHODS: An exploratory rapid qualitative study was conducted. Individual, telephonic and semi-structured interviews were conducted with patients who received a COVID-19 diagnosis confirmed by a PCR test and who had outpatient treatment for the disease. A thematic analysis was performed. RESULTS: Nine interviews were conducted (six female and three male participants). The main emerging themes were: life before COVID-19, living with the disease at home, recovery process, and Ineffective sanitary measures. Most of the participants highlighted the lack of information about their health and the uncertainty about COVID-19 as the cause of fear for their wellbeing. They also felt guilty for putting at risk others due to their COVID-19-positive status. CONCLUSION: The experiences of patients show the need to strengthen communication and information strategies for patients who receive outpatient care during the pandemic. This is key to reducing misinformation, fear and uncertainty about the progression of the disease and the potential recovery. Consequently, this could impact clinical outcomes and patient satisfaction.

[Evaluation of the state and implementation of the Hospital Clinical Forensic Units in Chile]. / Evaluación del estado e implementación de las Unidades Clínico Forense Hospitalarias en Chile.

BACKGROUND: Sexual violence has a several negative impact on women's health. Thus, the health system is a gateway for the multisector response to victims. In 2018, the Clinical Forensic Hospital Units (UCFH) in Chile were launched for this purpose. OBJECTIVE: To evaluate the state of implementation of the UCFH in the health services (HS) in Chile. METHOD: This is a quantitative descriptive, cross-sectional study. A survey was designed and applied through the Google Forms platform to the managers of the care and prevention network for victims of sexual violence (VSV) of each SS. The contact of each manager was requested by each HS in three ways: transparency law, lobby law, and telephone. Each HS was classified according to the existence or not of UCFH and for each unit the availability of resources was evaluated according to the recommendations of the Technical Standard of Attention to VSV of the Ministry of Health. Also, the functioning of each unit during the pandemic was evaluated. RESULTS: Twenty-four of the 29 HSs responded, of which 12 reported having UCFH. Of the 12 units, 50% had complete infrastructure, 58.3% had complete instruments, none had full human resources, 50% had partial HR, 50% had sampling complete, and 58. 3% had full health benefits. The function during the pandemic was affected in 25% of the units. CONCLUSION: Challenges persist in the implementation of the UCFH, with special limitations in the availability of human resources.

Fruit sugar hub: gene regulatory network associated with soluble solids content (SSC) in Prunus persica.

Chilean peach growers have achieved worldwide recognition for their high-quality fruit products. Among the main factors influencing peach fruit quality, sweetness is pivotal for maintaining the market's competitiveness. Numerous studies have been conducted in different peach-segregating populations to unravel SSC regulation. However, different cultivars may also have distinct genetic conformation, and other factors, such as environmental conditions, can significantly impact SSC. Using a transcriptomic approach with a gene co-expression network analysis, we aimed to identify the regulatory mechanism that controls the sugar accumulation process in an 'O × N' peach population. This population was previously studied through genomic analysis, associating LG5 with the genetic control of the SSC trait. The results obtained in this study allowed us to identify 91 differentially expressed genes located on chromosome 5 of the peach genome as putative new regulators of sugar accumulation in peach, together with a regulatory network that involves genes directly associated with sugar transport (PpSWEET15), cellulose biosynthesis (PpCSLG2), flavonoid biosynthesis (PpPAL1), pectin modifications (PpPG, PpPL and PpPMEi), expansins (PpEXPA1 and PpEXPA8) and several transcription factors (PpC3H67, PpHB7, PpRVE1 and PpCBF4) involved with the SSC phenotype. These results contribute to a better understanding of the genetic control of the SSC trait for future breeding programs in peaches.

Global hotspots and trends of nutritional supplements in sport and exercise from 2000 to 2024: a bibliometric analysis.

BACKGROUND: Nutritional supplements for sports and exercise (NSSE) can facilitate the exogenous replenishment of the body. This study provides the first extensive overview of NSSE research through bibliometric and visual analyses. METHODS: We searched the Web of Science Core Collection database for literature related to "NSSE" from 1st January 2000 to 8th March 2024. A total of 1744 articles were included. CiteSpace, VOSviewer, and Bibliometrix R package software were used to analyze the data. RESULTS: Research in the NSSE can be divided into steady growth, exponential growth, fluctuating stage, and surge stages. The United States is the most active country in this field. In recent years, the leading countries have been Croatia, Colombia, Slovenia, Chile, Egypt, China, and Thailand. The Australian Institute of Sports is the top research institution in terms of number of publications. Burke, LM from Australia published the most articles. Research in this area has primarily been published in Nutrients in Switzerland. The study population mainly consisted of men, and postmenopausal women were the main focus of the female group. Coronary heart and cardiovascular diseases continue to dominate research. CONCLUSION: Research on the NSSE is developing rapidly, with an annual growth trend. Insulin resistance, sports nutrition, inflammation, alpha-linolenic acid, limb strength performance, female sex, and gut microbiota are the focus of the current research and trends for future research. Future research should focus on improving the scientific training system for athletes and quality of training and life for the general public.

Oceanographical-driven dispersal and environmental variation explain genetic structure in an upwelling coastal ecosystem.

The seascape comprises multiple environmental variables that interact with species biology to determine patterns of spatial genetic variation. The environment imposes spatially variable selective forces together with homogenizing and diverging drivers that facilitate or restrict dispersal, which is a complex, time-dependent process. Understanding how the seascape influences spatial patterns of genetic variation remains elusive, particularly in coastal upwelling systems. Here, we combine genome-wide SNP data, Lagrangian larval dispersal simulated over a hydrodynamic model, and ocean environmental information to quantify the relative contribution of ocean circulation and environmental heterogeneity as drivers of the spatial genetic structure of two congeneric intertidal limpets, Scurria scurra and S. araucana, along the central coast of Chile. We find that a genetic break observed in both limpet species coincides with a break in connectivity shown by the Lagrangian dispersal, suggesting that mean ocean circulation is an important seascape feature, in particular for S. scurra. For S. araucana, environmental variation appears as a better predictor of genetic structure than ocean circulation. Overall, our study shows broad patterns of seascape forcing on genetic diversity and contributes to our understanding of the complex ecological and evolutionary interactions along coastal upwelling systems.

Follicular Lymphoma in Chile in the Adult Public Cancer Program: The Impact of Chemoimmunotherapy.

BACKGROUND: Follicular lymphoma (FL) is the most common indolent non-Hodgkin lymphoma (NHL) in the United States and Europe. However, data on FL from Latin America are scant. AIMS: This study aims at better understand the clinical features, treatment patterns and outcomes of patients with FL in Chile. Of special interest was to evaluate POD24 as an adverse marker. METHODS AND RESULTS: We collected retrospective data from 722 patients 15 years or older diagnosed with FL and treated in 17 cancer centers in Chile between 2000 and 2019. Time to first treatment (TTFT), progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method. Cox proportional-hazard regression models were fitted to investigate prognostic factor. The median age at diagnosis was 62 with a female predominance (63%); 73% of patients had advance stage disease and 68% had bone marrow involvement; 63% had intermediate or high FLIPI scores. The 1-year TTFT rate was 96%, and 30% of patients received chemoimmunotherapy. Adding rituximab to chemotherapy was associated with a higher complete response (69% vs. 60%; p < 0.001) and superior median OS (16 vs. 8 years; p < 0.001). Patients who experience POD24 had an inferior median OS (2.4 vs. 15 years). CONCLUSION: Our study shows a female predominance in patients with FL in Chile and confirms superior response and survival outcomes with adding rituximab to chemotherapy. Our study also confirms a poor OS in patients who experience POD24.

Hyperexpansion of genetic diversity and metabolic capacity of extremophilic bacteria and archaea in ancient Andean lake sediments.

BACKGROUND: The Andean Altiplano hosts a repertoire of high-altitude lakes with harsh conditions for life. These lakes are undergoing a process of desiccation caused by the current climate, leaving terraces exposed to extreme atmospheric conditions and serving as analogs to Martian paleolake basins. Microbiomes in Altiplano lake terraces have been poorly studied, enclosing uncultured lineages and a great opportunity to understand environmental adaptation and the limits of life on Earth. Here we examine the microbial diversity and function in ancient sediments (10.3-11 kyr BP (before present)) from a terrace profile of Laguna Lejía, a sulfur- and metal/metalloid-rich saline lake in the Chilean Altiplano. We also evaluate the physical and chemical changes of the lake over time by studying the mineralogy and geochemistry of the terrace profile. RESULTS: The mineralogy and geochemistry of the terrace profile revealed large water level fluctuations in the lake, scarcity of organic carbon, and high concentration of SO42--S, Na, Cl and Mg. Lipid biomarker analysis indicated the presence of aquatic/terrestrial plant remnants preserved in the ancient sediments, and genome-resolved metagenomics unveiled a diverse prokaryotic community with still active microorganisms based on in silico growth predictions. We reconstructed 591 bacterial and archaeal metagenome-assembled genomes (MAGs), of which 98.8% belonged to previously unreported species. The most abundant and widespread metabolisms among MAGs were the reduction and oxidation of S, N, As, and halogenated compounds, as well as aerobic CO oxidation, possibly as a key metabolic trait in the organic carbon-depleted sediments. The broad redox and CO2 fixation pathways among phylogenetically distant bacteria and archaea extended the knowledge of metabolic capacities to previously unknown taxa. For instance, we identified genomic potential for dissimilatory sulfate reduction in Bacteroidota and α- and γ-Proteobacteria, predicted an enzyme for ammonia oxidation in a novel Actinobacteriota, and predicted enzymes of the Calvin-Benson-Bassham cycle in Planctomycetota, Gemmatimonadota, and Nanoarchaeota. CONCLUSIONS: The high number of novel bacterial and archaeal MAGs in the Laguna Lejía indicates the wide prokaryotic diversity discovered. In addition, the detection of genes in unexpected taxonomic groups has significant implications for the expansion of microorganisms involved in the biogeochemical cycles of carbon, nitrogen, and sulfur. Video Abstract.

Nutritional composition, fatty acids profile and immunoglobulin G concentrations of mare milk of the Chilean Corralero horse breed.

The objective of the present study was to characterize the nutritional composition, fatty acid profile, and IgG concentration of the milk produced by Chilean Corralero horse (CCH) mares from breeding farms located in southern Chile. Forty-five milk samples were collected from three of the biggest breeding farms (coded as A, B and C) specialized in breeding and selection of CCH in Chile (15 mares sampled per farm). Farms differed in days in milk (DIM). A negative association between DIM and ash, milk protein, milk solids, saturated fatty acids (SFA), and gross energy (GE) was found, whereas DIM had a positive association with monounsaturated fatty acids (MUFA). Milk components like fat, lactose, and energy content varied independently of DIM, indicating other influencing factors such as farm-specific management practices. Offspring sex moderately affected GE content, with milk from mares bearing female offspring having higher GE. Macronutrient profiles of the CCH mares' milk were within the reported range for other horse breeds but tended to have lower fat and total solids. Compared to cow and human milk, horse milk is richer in lactose and lower in fat and protein. Immunoglobulin G concentration was only affected by the farm (B > A) which could be linked to dietary factors and pasture composition rather than maternal parity or other known factors. Overall, CCH mare milk has notable nutritional characteristics, with implications for both foal health and potential human consumption, posing less cardiac risk compared to cow's milk as indicated by lower atherogenic and thrombogenic indices.
