Article Abstract
The increased interest in donkeys because of their milk has led to changes in their farm management. Little is known about the effect of the farming systems on donkey health and welfare. Measuring hair cortisol concentrations is an emerging method to assess stress in animals. To the best of our knowledge, no cortisol assessment has been done on dairy donkeys; similarly, only a few studies have investigated donkey haematological values. The aim of this study was to evaluate the effects of the lactation phase, parity and season on blood parameters, milk yield and quality and hair cortisol in dairy donkeys. Individual samples of milk, blood and mane hair were taken from twenty jennies at 1, 6 and 10 months after parturition. Higher values of hair cortisol were found in the first sampling, suggesting temporary stress during the peri-parturition. The parity influenced the number of blood cells, which was lower in the pluriparous jennies. The season affected milk quality and mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration. The latters might represent the adaptation to the environmental conditions. This study contributes to a better understanding of the biochemical processes occurring in lactating jennies, and to their physiological and wellbeing status.

Background: Hair analysis is increasingly utilized in psychoneuroendocrine research to assess long-term hormonal activity. A critical practical question when using this method is how long hair samples can be stored without compromising data quality, yet this issue remains insufficiently researched. Here, we report data from a first systematic, well-controlled within-subject investigation into the impact of storage duration (over 12 months) on hair cortisol and other common hair analytes.

Background: People with a low socioeconomic position (SEP) are at higher risk for type 2 diabetes (T2D). A social gradient in chronic stress might be a potential explanation for this relationship. Chronic stress as a result of low SEP might impact biomarkers such as cortisol and cortisone levels.

Parental incarceration can be stressful for children, leading to less optimal development. Although parental incarceration typically takes place among other adversities, resilience processes occur in many families, for example, in instances of secure child-caregiver attachment relationships. Yet, it is not known how secure attachments are associated with stress processes in children with incarcerated parents, especially in the context of other risks.

Introduction: The aim of this study is to report the case of nonclassical congenital adrenal hyperplasia (NCAH) observed in a female child, and to present the management of the surgical-orthodontic rehabilitation, through clinical and histological oral findings.
Method: A 13-year-old female was referred to our department for dental evaluation. The patient was affected by NCAH, confirmed by hormonal and genetic analysis from the age of 6 years, due to the appearance of premature pubic hair.

Acute stress affects interoception, the processing and perception of signals from inside the body. In contrast, the effects of chronic stress on interoception remain largely unknown, although chronic stress is a potential risk factor for disorders involving interoceptive alterations. This study aimed at investigating the impact of both acute and chronic stress on two key facets of interoception: interoceptive accuracy (IAc) and interoceptive attention (IAt).
