Pesticides have been pointed out as hormone disruptors and may significantly affect the prognosis of hormone-dependent diseases such as breast cancer (BC). Here, we investigated the impact of occupational pesticide exposure on systemic cortisol levels in female rural workers diagnosed with BC. Occupational exposure was assessed by interviews with a standardized questionnaire. Plasma samples (112 from pesticide-exposed women and 77 from unexposed women) were collected in the afternoon, outside the physiological cortisol peak, and analyzed by a chemiluminescent paramagnetic immunoassay for the quantitative determination of cortisol levels in serum and plasma. The results from both groups were categorized according to patients' clinicopathological and exposure data. BC pesticide-exposed women presented higher levels of cortisol than the unexposed. Higher cortisol levels were also detected in the exposed group with more aggressive disease (triple-negative BC), with tumors over 2 cm, with lymph node metastases, and with high risk of disease recurrence and death. These findings demonstrated that there is an association between pesticide exposure and BC that affected cortisol levels and correlated to poor disease prognosis.

ABSTRACT Objective: COVID-19 is a multisystem immunoinflammatory disorder, and the hypothalamo–pituitary-adrenal (HPA) axis may be affected by SARS-CoV-2 as well as by steroid treatment during the illness. Information on the HPA axis after recovering from COVID-19, especially in those treated with steroids, is sparse. Hence, this study was performed to evaluate the hypothalamo-pituitary-adrenal axis during the post-COVID-19 period in patients treated with steroids during the illness. Subject and methods: This prospective study involved 60 patients aged 18-60 years who had recovered from moderate or severe COVID-19 and had received steroid treatment during the illness. The HPA axis was assessed with a low-dose (1 mcg) adrenocorticotropic hormone stimulation test at 3, 6 and 9 months in the post-COVID period. Results: The HPA axis was suppressed in 31.66% of the patients at 3 months and 5% at 6 months; however, all patients recovered at 9 months. Cumulative steroid use during the illness was inversely correlated with stimulated cortisol at 3 months in the post-COVID period. Fatigue was present in 58.33% of the patients at 3 months and was more prevalent in those with HPA axis suppression. Conclusion: Nearly one-third of the patients with moderate to severe COVID-19 who were treated with steroids had suppressed HPA axis at 3 months, with gradual recovery over a period of 9 months. Cumulative steroid equivalent dose, but not disease severity, was predictive of HPA axis suppression at 3 months.

ABSTRACT This study aimed to investigate the impact of pig breed on stress levels and meat quality in two commercial pig farms in the north-eastern part of Romania. One farm raised 52 Mangalita pure-bred pigs and the other 82 Duroc x Landrace crossbred pigs. Serum cortisol, a biomarker of stress, and serum glucose were measured before and after slaughtering, while meat pH was measured at 45 minutes and 24 hours post-mortem. Results showed that the Duroc x Landrace crossbred pigs had higher serum cortisol and glucose values before and after slaughtering compared to the Mangalita purebred pigs. The meat pH values of the two breeds were similar, with the pH45 and pH24 values being 6.67 and 5.48 for Duroc x Landrace crossbred and 6.53 and 5.52 for Mangalita purebred, respectively. These results suggest that pig breed can have an impact on stress levels and meat quality, with Duroc x Landrace crossbred pigs showing higher stress levels and meat quality being not affected by the breed of pig. Further research is needed to confirm these findings and to understand the underlying mechanisms.

RESUMO Este estudo teve como objetivo investigar o impacto da raça suína nos níveis de estresse e na qualidade da carne em duas fazendas comerciais de suínos, no nordeste da Romênia. Uma fazenda criou 52 suínos puros Mangalita, e a outra 82 suínos mestiços Duroc x Landrace. O cortisol sérico, um biomarcador de estresse e a glicose sérica foram medidos antes e após o abate, enquanto o pH da carne foi medido aos 45 minutos e 24 horas post mortem. Os resultados mostraram que os suínos mestiços Duroc x Landrace apresentaram valores séricos de cortisol e de glicose mais elevados, antes e após o abate, em comparação com os suínos puros Mangalita. Os valores de pH da carne das duas raças foram semelhantes, sendo os valores de pH45 e pH24 de 6,67 e 5,48 para o mestiço Duroc x Landrace e de 6,53 e 5,52 para o puro sangue Mangalita, respectivamente. Esses resultados sugerem que a raça suína pode ter um impacto nos níveis de estresse e na qualidade da carne, com os porcos mestiços Duroc x Landrace apresentando níveis mais altos de estresse e a qualidade da carne não sendo afetada pela raça do porco. Mais pesquisas são necessárias para confirmar esses achados e entender os mecanismos subjacentes.

Resumen Introducción Son necesarios tratamientos basados en evidencia para mujeres víctimas de violencia de pareja (IPV), con trastornos relacionados con estrés como ansiedad, depresión y riesgo suicida y alteraciones en la reactividad del cortisol. Objetivo Comparar los cambios en la sintomatología depresiva, ansiosa, calidad de vida y reactividad del cortisol después de aplicar Terapia de Aceptación y Compromiso (ACT, basada en la flexibilidad psicológica) o Terapia Interpersonal (IPT, basada en el empoderamiento) en mujeres expuestas a IPV y compararlos en función al pensamiento suicida. Método Una muestra clínica de 50 mujeres (entre 21 y 74 años) fueron asignadas aleatoriamente a recibir ACT o IPT, completaron antes y después, cuestionarios sobre IPV, calidad de vida, depresión y ansiedad, y mediciones de cortisol (basal, 15, 30 y 45 minutos después de un reto cognitivo) en saliva en respuesta a un reto cognitivo. Utilizamos modelos de Ecuaciones de Estimación generalizada para analizar los datos. Resultados Mejoraron significativamente todas las variables, independientemente del tipo de psicoterapia y del pensamiento suicida. Antes de la intervención, las mujeres con ideación suicida presentaron depresión y ansiedad severas, peor calidad de vida e hiper-respuesta de cortisol, en contraste con las mujeres sin ideación, quienes presentaron síntomas moderados y una respuesta de cortisol plana. El cortisol disminuyó en todas las mujeres después de ambas terapias. Discusión y conclusión Ambas terapias IPT y ACT mejoraron la salud mental y calidad de vida de las mujeres con IPV y modificaron la reactividad del cortisol, incluyendo a las pacientes que reportaron ideación suicida.

Abstract Introduction There is a growing need to implement evidence-based psychological treatments for women victims of intimate partner violence (IPV) who commonly experience stress-related disorders such as anxiety, depression, or suicide risk, as well as altered cortisol reactivity. Objective 1. To compare the changes in depressive and anxious symptomatology, quality of life, and cortisol reactivity after two different interventions, Acceptance and Commitment Therapy (ACT, based on psychological flexibility) or Interpersonal Therapy (IPT, based on empowerment) in women exposed to IPV. 2. To compare the changes in relation to the presence of suicide thoughts. Method A clinical sample of 50 women (ages 21-74) randomly assigned to attend ACT or IPT, completed pre- and post-intervention questionnaires about intimate partner violence, quality of life, depression, anxiety, and measurements of salivary cortisol reactivity (basal, 15, 30, and 45 minutes after a cognitive challenge). We used Generalized Estimating Equation Models for data analysis. Results There was a significant improvement post-intervention in all variables, regardless of the type of psychotherapy or the presence of suicide thoughts. Before interventions, women that reported suicide thoughts had severe symptoms of depression, anxiety, worse quality of life, and a cortisol hyper-response profile, in contrast to women without suicide thoughts who had moderate symptoms and no cortisol response. Cortisol response to the cognitive test decreased in all women after both therapies. Discussion and conclusion Although different psychological approach, ACT, and IPT effectively improved mental health, quality of life, and changed cortisol reactivity of women exposed to IPV, including women at suicide risk.

Abstract Primary aldosteronism is the most common cause of secondary hypertension. When unilateral disease is present, patients can be treated curatively by adrenalectomy. Adrenal vein sampling (AVS) is considered essential for discrimination between unilateral versus bilateral disease. Knowledge of normal and variant anatomy of the adrenal veins is important to avoid misleading results and increase technical success. The main reason for technical failure of AVS is the inability to catheterize the right adrenal vein. Pre-procedural CT imaging can help identify the venous anatomy of the adrenals. To validate the technical success of AVS, the catheterization index is calculated comparing the cortisol levels in each adrenal gland with those of the inferior vena cava. To assess the laterality index, the aldosterone levels are compared between both adrenals. We generally use a femoral access and a 4Fr Berenstein catheter for the left adrenal vein and a 5Fr Cobra, Simmons or Micahelson for the right adrenal vein. Some centers adopt an intravenous perfusion of a synthetic peptide of the adrenocorticotropic hormone immediately prior to the procedure to stimulate the adrenal glands. AVS is a safe and feasible procedure, with low risk of failure. Due to the technical difficulties of execution, especially right adrenal vein cannulation, AVS has low usage among hospital centers. The learning curve is estimated to be around 20 to 30 procedures, with a maintenance of about 15 annual procedures to achieve satisfactory results.

Resumo O hiper-aldosterolismo primário é a causa mais comum de hipertensão secundária. Quando originado por patologia unilateral, pode ser tratado curativamente por adrenalectomia. O doseamento hormonal por cateterismo das veias supra-renais (VSRs) é essencial para discriminar entre patologia uni versus bilateral. O conhecimento da anatomia normal e variantes das VSRs é importante para evitar falsos negativos e aumentar o sucesso técnico. A principal causa de insucesso técnico deve-se à dificuldade na cateterização da VSR direita. A avaliação por TC pré-procedimento pode ajudar, ao permitir avaliar a anatomia vascular e o posicionamento das glândulas supra-renais. Para validar a correta cateterização das VSRs, é necessário realizar o doseamento de cortisol, permitindo calcular o índice de seletividade (comparativamente aos valores de cortisol da veia cava inferior). Para determinar o índice de lateralidade é utilizado o doseamento de aldosterona (comparativamente aos valores da VSR contra-lateral). Geralmente utilizamos um acesso femoral e o catéter Berenstein 4Fr para a VSR esquerda e os cateteres Cobra 5 Fr / Simmons 5 Fr / ou Micahelson 5 Fr para a VSR direita. Embora não seja consensual, alguns centros efetuam a perfusão de um análogo da hormona adrenocorticotrópica imediatamente antes do procedimento para estimular a glândula. O cateterismo das VSRs é um procedimento seguro, com baixas taxas de complicações. No entanto, devido à dificuldade de execução técnica, principalmente da cateterização da VSR direita, não é amplamente realizado. Estima-se que a curva de aprendizagem ronde os 20-30 casos, com manutenção de 15 procedimentos anuais para manter resultados satisfatórios.

ABSTRACT The aim of study was to determine the relationship between metabolic parameters, body weight and body growth of piglets at birth and weaning. The experiment included 80 piglets obtained from F1 generation sows. Body weight was measured at birth (BW0), 24h (BW1) after birth and on day 25 (at weaning, BW2). Blood sampling was performed at the beginning of life (3rd day after birth) and at weaning (21st day after birth). BW0 and BW1 positively correlated with cholesterol and negatively with urea values at the beginning of life and RBC values at weaning. BW2 positively correlates with albumin and cortisol values at the beginning of life, total proteins, and globulins at weaning, and negatively correlates with erythrocyte values at weaning. Piglet growth from birth to weaning (BWG2-0) correlates positively with total proteins, albumin, and cortisol at the beginning of life and total proteins at weaning. ROC analysis shows that MCHC, TPROT, GLOB, CHOL and AST at the beginning of life can distinguish fast-growing from slow-growing piglets from birth to weaning period. The use of blood parameters enables early recognition of growth rate in piglets, which can help to optimize all further steps to achieve the best possible growth.

RESUMO O objetivo do estudo foi determinar a relação entre parâmetros metabólicos, peso corporal e crescimento corporal de leitões ao nascimento e desmame. A experiência incluiu 80 leitões obtidos de porcas da geração F1. O peso corporal foi medido ao nascimento (BW0), 24h (BW1) após o nascimento e no dia 25 (no desmame, BW2). A amostragem de sangue foi realizada no início da vida (3º dia após o nascimento) e no desmame (21º dia após o nascimento). BW0 e BW1 correlacionaram-se positivamente com o colesterol e negativamente com os valores de uréia no início da vida e com os valores de hemácias no desmame. BW2 correlaciona-se positivamente com os valores de albumina e cortisol no início da vida, proteínas totais e globulinas no desmame, e negativamente com os valores de eritrócitos no desmame. O crescimento do leitão desde o nascimento até o desmame (BWG2-0) se correlaciona positivamente com as proteínas totais, albumina e cortisol no início da vida e com as proteínas totais no desmame. A análise ROC mostra que MCHC, TPROT, GLOB, CHOL e AST no início da vida pode distinguir leitões de crescimento rápido de leitões de crescimento lento desde o nascimento até o desmame. O uso de parâmetros sanguíneos permite o reconhecimento precoce da taxa de crescimento em leitões, o que pode ajudar a otimizar todas as etapas posteriores para alcançar o melhor crescimento possível.

Resumen Introducción: La placenta sintetiza y secreta varias hormonas que permiten la regulación del embarazo, el trabajo de parto y la adaptación metabólica materno-fetal. Su comportamiento asociado al tipo de parto puede dar información relevante sobre efectos epigenéticos. Objetivo: Describir el tipo de parto con los niveles de oxitocina, cortisol y hormonas tiroideas en plasma de cordón umbilical al nacer. Método: A 50 mujeres con embarazos principalmente normales se les cuantificaron los niveles neurohormonales en plasma de cordón umbilical, obtenido inmediatamente tras el periodo expulsivo. Los resultados se incorporaron a la base de datos clínicos de cada participante y se analizaron con Stata v.14.0. El protocolo fue aprobado por el comité de ética. Resultados: Hubo 33 partos vaginales (12 espontáneos, 13 acelerados y 8 inducidos) y 17 cesáreas (7 electivas y 10 de urgencia). Se observaron mayores niveles de cortisol en los partos vaginales acelerados; las cesáreas tuvieron menores niveles de cortisol y hormona estimulante de la tiroides. Las intervenciones clínicas, con altos o bajos niveles hormonales, están en directa relación con el tipo de parto. Conclusiones: El cortisol y la hormona estimulante de la tiroides medidos en plasma de cordón umbilical variaron según el tipo de parto. Esto es una primera cuantificación de hormonas en plasma de cordón umbilical y su posible regulación placentaria a propósito del tipo de parto.

Abstract Introduction: The placenta synthesizes and secretes several hormones allowing the regulation of pregnancy, labor and maternal-fetal metabolic adaptation. Their behavior associated with the type of delivery, may provide relevant information on epigenetic effects. Objective: To describe the type of delivery with the levels of oxytocin, cortisol and thyroid hormones in umbilical cord plasma at birth. Method: Neurohormonal levels from umbilical cord plasma obtained immediately post expulsion, were quantified in 50 women with mainly normal pregnancies. Results incorporated into the clinical database of each participant, statistically analyzed in Stata v.14.0. Protocol approved by ethics committee. Results: 33 were vaginal deliveries (12 spontaneous, 13 accelerated, 8 induced) and 17 cesarean sections (7 elective and 10 emergency). Higher cortisol levels were observed in accelerated vaginal deliveries, cesarean sections had lower cortisol and thyroid stimulating hormone levels. While clinical interventions, with high or low hormone levels, were related to the type of delivery. Conclusions: Cortisol and thyroid stimulating hormone measured in umbilical cord plasma varied according to the type of delivery. This is a first quantification of hormones in umbilical cord plasma and their possible placental regulation in relation to the type of delivery.

ABSTRACT Introduction: Pituitary apoplexy is a syndrome that occurs as a result of an ischemic or hemorrhagic lesion in the pituitary gland, leading to a deficiency of pituitary hormones. It manifests in the form of neurological deterioration with thunderclap headache as the main symptom, with meningeal irritation being an infrequent manifestation. Methods: We present the case of a 53-year-old woman with a history of prolactin-producing madroadenoma that began with headache, nausea and impaired level of consciousness. Incomplete hypopituitarism with normal cortisol level is detected. Cerebrospinal fluid (CSF) is consistent with an aseptic pleocytosis unresponsive to antibiotic therapy. It is associated with oculomotor paresis and a cranial MRI reveals bleeding in the pituitary adenoma with involvement of the cavernous sinus. Results: the initial suspicion is bacterial meningoencephalitis due to fever, stupor and CSF with pleocytosis, although no microorganism is identified and there is no response to antibiotics. CSF from stroke shows aseptic pleocytosis due to meningeal irritation of the subarachnoid space from bleeding and necrosis of the gland. Hypopituitarism can be partial or complete, selective deficiency being more frequent. ACTH deficiency deserves special attention due to the morbidity and mortality that adrenal failure entails. Ophthalmoparesis translates involvement of the cavernous sinus due to an increase in sellar pressure. Conclusions: We emphasize the importance of having a suspected diagnosis of apoplexy in case of an acute neurological condition, to direct the pertinent investigations with hormonal determination and thus initiate early replacement therapy and a neurosurgical approach if necessary; requiring a multidisciplinary management.

RESUMEN Introducción: La apoplejía hipofisaria es un síndrome que se produce como consecuencia de una lesión isquémica o hemorrágica en la glándula pituitaria dando lugar a un déficit de hormonas hipofisarias. Se manifiesta en forma de deterioro neurológico con cefalea en trueno como síntoma prínceps, siendo la irritación meníngea una manifestación infrecuente. Métodos: Presentamos el caso de una mujer de 53 años con antecedente de madroadenoma productor de prolactina que comienza con cefalea, náuseas y deterioro de nivel de consciencia. Se detecta un hipopituitarismo incompleto con nivel de cortisol normal. El líquido cefalorraquídeo (LCR) es consistente con una pleocitosis aséptica sin respuesta a terapias antibióticas. Asocia paresia oculomotora y una RM craneal revela sangrado en el adenoma hipofisario con compromiso de seno cavernoso. Resultados: la sospecha inicial es una meningoencefalitis bacteriana por la fiebre, estupor y LCR con pleocitosis, si bien no se identifica microorganismo y no hay respuesta a antibióticos. El LCR de la apoplejía muestra una pleocitosis aséptica por irritación meníngea del espacio subaracnoideo por el sangrado y la necrosis de la glándula. El hipopituitarismo puede ser parcial o completo, siendo más frecuente el déficit selectivo. Especial atención merece el déficit de ACTH por la morbimortalidad que conlleva el fallo adrenal. La oftalmoparesia traduce implicación de seno cavernoso por incremento en la presión selar. Conclusiones: Destacamos la importancia de tener una sospecha diagnóstica de apoplejía ante un cuadro neurológico agudo para dirigir las investigaciones pertinentes con determinación hormonal y así iniciar una terapia sustitutiva temprana y una actitud neuroquirúrgica en caso de ser necesaria; precisando un manejo multidisciplinar.

Resumen: Introducción: La relación entre producción de leche materna y la música ha sido reportada en diversas publicaciones científicas. No hay publicaciones en Uruguay que analicen esta relación. Este estudio fue realizado por el Instituto Universitario CEDIIAP junto a la Universidad ORT, el Banco de Leche Humana del Hospital Pereira Rossell (CHPR), de la Administración de los Servicios de Salud del Estado. Fue aprobado por el Comité de Ética del CHPR. Objetivo: evidenciar la relación entre el estímulo musical y la producción de leche de madres de recién nacidos pretérmino internados en Cuidados Intensivos del CHPR. Material y métodos: estudio cuasiexperimental, de corte longitudinal, prospectivo, diseño doble: intervención antes después y en paralelo (un grupo contra el otro) utilizando audición de canciones elegidas por las madres con andamiento modificado. Criterios de inclusión: cohorte de madres de recién nacidos ≤ 34 semanas de gestación, sin alimentación a pecho directo, medicación psiquiátrica o que afectara la producción de leche. Se analizó cortisol en saliva y volumen de leche. Como análisis multivariado final, se aplicó el modelo lineal general de medidas repetitivas. Resultados: el estudio se realizó entre marzo de 2017 y agosto de 2018 con 31 madres (15 intervención, 16 control). El grupo intervención presentó mayor producción láctea en los 2 primeros días y disminución del 57 % en niveles de cortisol frente al grupo control. Conclusiones: más allá de las limitaciones del trabajo, los resultados apuntan a que la musicoterapia podría colaborar en la disminución del estrés, el disfrute de la lactancia materna y, consecuentemente, en una mayor producción de leche.

Summary: Introduction: the relationship between breast milk production and music has been previously reported in several peer reviewed journals. There are no studies in Uruguay analyzing this relationship. The present study was performed by the CEDIIAP University Institute jointly with the ORT University, at the Pereira Rossell Hospital Human Milk Bank (CHPR) of the Administration of State Health Services (ASSE) in Montevideo. It has been approved by the CHPR’s Ethics Committee. Objective: demonstrate the influence of musical stimulation on milk production of mothers with preterm newborns admitted in the CHPR Neonatology Intensive Care Unit. Material and Methods: longitudinal, prospective experimental study with double design: intervention before, simultaneous (one group against the other) and after the study. We used the music therapy technique of listening to songs chosen by the mothers and modified gait. Milk volume was quan- tified, and cortisol presence was analyzed in saliva. The General Linear Model of repetitive measures was applied. Inclusion criteria: cohort of mothers of newborns ≤ 34 weeks of gestation, without direct breastfeeding, psychiatric medication or affecting milk production. Saliva cortisol levels and milk volume were analyzed. As a final multivariate analysis, the General Linear Model of repetitive measures was applied. Results: the study was carried out from March 2017 till August 2018 with a total of 31 mothers (15 intervention, 16 control). Higher milk production in the first two days and a decrease of 57% in cortisol levels were observed in the intervention group compared to the control group. Conclusions: in spite of the limitations of this paper, our results suggest that music therapy can help to reduce the stress and increase the enjoyment of breastfeeding and consequently generate a higher milk production.

Resumo: Introducion: a relação entre produção do leite materno e a música foi apontada com evidências científicas em vários jornais. Não existem publicações no Uruguai que analisem esta relação. Este estudo foi realizado pelo Instituto universitário CEDIIAP junto com a Universidade ORT, o Banco de Leite Humano do Hospital Pereira Rossell (CHPR) da Administração dos Serviços de Saúde do Estado. Foi aprovado pelo Comité de Ética do CHPR. Objetivo: evidenciar a relação entre o estímulo musical e a produção do leite de mães com recém nascidos prematuros internados na unidade de cuidados intensivos do CHPR. Material e metodo: estudo quase experimental de corte longitudinal, prospectivo com desenho duplo: intervenção antes, depois e em paralelo (um grupo contra o outro) utilizando a audição de canções escolhidas pelas mães e andamento modificado. Critérios de inclusão: coorte de mães de recém nascidos ≤ 34 semanas de gestação sem alimentação a peito direto, nem medicação psiquiátrica ou que afetara a produção de leite. Foi analisado o cortisol em saliva e o volumem de leite. Aplicouse o Modelo Linear General de medidas repetitivas como análise multivariado final. Resultados: o estudo foi realizado entre março 2017 e agosto 2018 com 31 mães (15 do grupo intervenção, 16 do grupo controle). Foi observada maior produção láctea no grupo de intervenção nos dois primeiros dias e diminuição de 57% nos níveis de cortisol em relação ao grupo controle. Conclusões: além das limitações do paper, os resultados apontam para que a musicoterapia poderia colaborar na diminuição do estresse, o desfrute da lactância materna e consequentemente poderiam resultar em uma maior produção de leite.

BACKGROUND: Texting has become central to social life, with adverse effects on physiological functioning. Research into the impact of texting on cortisol secretion is limited. AIM: Thus study aimed to determine how receiving mobile text messages affected salivary cortisol concentrations and investigate the moderating effects of stress, anxiety and depression on cortisol secretion. SETTING: Undergraduate physiology students attending physiology lectures at the Faculty of Health Sciences, University of the Free State, 2016. METHODS: An experimental, crossover, quantitative design was used. Participants were involved over two consecutive days, receiving mobile text messages (intervention) on one day and acting as their own control on the other. Self-reported data on stress, anxiety, depression and subjective experience of the study, and saliva samples were collected. Text frequency and wording (neutral, positive, negative) were varied among participants. RESULTS: Forty-eight students participated in the study. Salivary cortisol concentrations did not differ significantly between the intervention and control days. High anxiety levels were associated with increased cortisol concentrations. No associations with cortisol concentrations were documented in low to moderate anxiety, stress, depression or how participants experienced the intervention. There were no significant differences between text frequency, text emotion and change in cortisol concentrations on the intervention day CONCLUSION: Receiving mobile text messages did not elicit a significant cortisol response in participants. CONTRIBUTION: Findings added to the body of knowledge about the effect of texting on student learning by measuring salivary cortisol concentrations in a lecture setting, with investigation into the moderating effects of stress, anxiety, depression and participants' subjective experience.

The objective of the current study was to evaluate the effects of dietary supplementation with chromium yeast (Cr-yeast) and dihydropyridine (DHP) on nutrient utilization, milk composition, and antioxidative status of prepartum dairy cows under heat stress. Twenty-four perinatal dairy cows (600 ± 14 kg; parity 2-3) were divided into three groups and fed the same basal diet with no supplement (control group), 8 g of Cr-yeast (Cr-yeast group), or 3 g of DHP (DHP group) per day. The experimental period consisted of a 7-d adaptation period and a 30-d data collection period from day 27 prepartum to day 3 postpartum. The temperature humidity index (THI) observed at daytime during the trial period exceeded 72, and the mean daily THI was 79.43. Norepinephrine in the Cr-yeast group decreased in prepartum cows. Serum cortisol in Cr-yeast or DHP group cows was lower in the postpartum period than in the control; however, serum cortisol levels decreased in the DHP group in the prepartum period. Dietary supplementation with Cr-yeast increased the digestibility of ether extract and the concentration of milk fat, while the solid non-fat (SNF) level was reduced. In the DHP group, the lactoprotein content was higher than the control. Total antioxidant capacity (T-AOC) was higher and the malondialdehyde (MDA) content tended to increase before calving in the Cr-yeast and DHP groups. Dietary supplementation with Cr-yeast or DHP can relieve the adverse impact caused by heat stress in prepartum dairy cows.

SUMMARY OBJECTIVE: This study aimed to determine whether maternal cortisol levels affect fetal heart rate patterns in primiparous pregnant women in the third trimester. METHODS: This cross-sectional descriptive study included 400 primiparous pregnant women with uncomplicated pregnancies between November and December 2022. The study included primiparous pregnant women over 18 years old in the third trimester who had not exercised for at least 2 h before the fetal heart rate monitoring and had a healthy pregnancy without consuming any food or drink. Fetuses with decelerating heartbeats and pregnant women who showed uterine contraction and cervical dilation during the fetal heart rate monitoring were excluded from the study. Research data were collected with the data collection form. The fetal heart rate data were collected using a cardiotocograph. At least two accelerations during the 20-min nonstress test period were the basis for diagnosing a reactive nonstress test. About 5 mL of maternal saliva for cortisol measurements was collected before fetal heart rate monitoring. Research data were analyzed with IBM SPSS Statistics for Macintosh, Version 28.0. A p-value of <0.05 was considered significant. RESULTS: There were no significant differences in the comparison of the groups in terms of education and income status, family type, fetal gender, pregnancy planning status, BMI and age averages, or gestational week averages (p>0.05). The number of at least two accelerations required for the diagnosis of reactive NST was also higher in Group 1 (maternal salivary cortisol level ≤24.20). A moderately positive relationship between fetal heart rate and maternal salivary cortisol was observed (r=0.448, p=0.000). In total, 11.9% of the total change in fetal heart rate level is explained by maternal cortisol (R2=0.119). Maternal cortisol increases fetal heart rate level (ß=0.349). CONCLUSION: These findings suggest that stress in primiparous pregnant women with high cortisol levels may influence fetal heart rate patterns. It was revealed that the increase in cortisol level, considered a stress hormone, may be a harbinger of fetal tachycardia.
