Sara L Kornfield, Liisa Hantsoo, C Neill Epperson
PURPOSE OF REVIEW: This review highlights the neurobiological aspects of sex differences in posttraumatic stress disorder (PTSD), specifically focusing on the physiological responses to trauma and presents evidence supporting hormone and neurosteroid/peptide differences from both preclinical and clinical research. RECENT FINDINGS: While others have suggested that trauma type or acute emotional reaction are responsible for women's disproportionate risk to PTSD, neither of these explanations fully accounts for the sex differences in PTSD...

Stress is associated with the development of mental disorders such as depression and psychosis. The ability to regulate emotions is likely to influence how individuals respond to and recover from acute stress, and may thus be relevant to symptom development. To test this, we investigated whether self-reported emotion regulation predicts the endocrine, autonomic, affective, and symptomatic response to and recovery from a stressor. Social-evaluative stress was induced by the Trier Social Stress Test (TSST) in N = 67 healthy individuals (53...

Michael Kirsch, Wolfgang Mertens
Doubters of Freud's theory of drives frequently mentioned that his approach is outdated and therefore cannot be useful for solving current problems in patients with mental disorders. At present, many scientists believe that affects rather than drives are of utmost importance for the emotional life and the theoretical framework of affective neuroscience, developed by Panksepp, strongly underpinned this view. Panksepp evaluated seven so-called command systems and the SEEKING system is therein of central importance...

REVIEW
Sang Won Jeon, Yong-Ku Kim
Although depression has generally been explained with monoamine theory, it is far more multifactorial, and therapies that address the disease's pathway have not been developed. In this context, an understanding of neuroinflammation and neurovascular dysfunction would enable a more comprehensive approach to depression. Inflammation is in a sense a type of allostatic load involving the immune, endocrine, and nervous systems. Neuroinflammation is involved in the pathophysiology of depression by increasing proinflammatory cytokines, activating the hypothalamus-pituitary-adrenal axis, increasing glucocorticoid resistance, and affecting serotonin synthesis and metabolism, neuronal apoptosis and neurogenesis, and neuroplasticity...

Anomalous protein-protein interactions (PPIs) have been correlated to a variety of disease states, such as cancer, infectious disease, neurological disorders, diabetes, endocrine disorders and cardiovascular disease. Stapled peptides are an emerging intervention for these PPIs due to their improved structural rigidity and pharmacokinetic properties relative to unstapled peptides. This review details the most recent advances in the field of stapled peptide therapeutics, including the increasing variety of PPIs being targeted and types of peptide staples being employed...

PURPOSE OF REVIEW: Genetic obesity is responsible for up to 7% of severe childhood obesity. Although current Pediatric Endocrine Society guidelines recommend assessment of children with early-onset morbid obesity and hyperphagia for underlying genetic disorders, a vast majority of patients are not being appropriately screened for genetic obesity syndromes. RECENT FINDINGS: With advances in genetic testing, more genetic causes of obesity are being identified. Treatments are likely to be individualized, depending on the cause of the obesity, and must be targeted at addressing the underlying cause...

The reproductive endocrine systems are vastly different between male and female. This sexual dimorphism of endocrine milieu originates from sex-specific differentiation of the somatic cells in the gonads during fetal life. The majority of gonadal somatic cells arise from the adrenogonadal primordium. After separation of the adrenal and gonadal primordia, the gonadal somatic cells initiate sex-specific differentiation during gonadal sex determination with the specification of the supporting cell lineages: Sertoli cells in the testis vs...

Steinert's disease or Myotonic Dystrophy type 1 (DM1) is an autosomal dominant multisystemic disorder characterized by myotonia, muscle and facial weakness, cataracts, cognitive, endocrine and gastrointestinal involvement, and cardiac conduction abnormalities. Although mild myocardial dysfunction may be detected in this syndrome with age, overt myocardial dysfunction with heart failure is not frequent. Cardiac resynchronization therapy is an effective treatment to improve morbidity and reduce mortality in patients with DM1 showing intra-ventricular conduction delay and/or congestive heart failure...

Myotonic dystrophy type 1 is a multisystemic disorder characterized by myotonia, muscle weakness and involvement of several organs and apparatus such as heart, lungs, eye, brain and endocrine system. Hypogonadism and reproductive abnormalities are frequently reported. A progressive testicular atrophy occurs in about 80% in the affected males leading to Leydig cell hyperproliferation and elevated basal follicle stimulating hormone (FSH) levels. Anti-Müllerian hormone (AMH) - a dimeric glycoprotein belonging to the super-family of transforming grow factor beta (TGF-beta) - is the earliest Sertoli cell hormone secreted in males and, together with inhibin B and FSH, is an important indicator of Sertoli cell function...

Margaret R Bell
Postnatal development includes dramatic changes in gonadal hormones and the many social behaviors they help regulate, both in rodents and humans. Parental care-seeking is the most salient social interaction in neonates and infants, play and pro-social behaviors are commonly studied in juveniles, and the development of aggression and sexual behavior begins in peripubertal stages but continues through late adolescence into adulthood. While parental behaviors are shown after reproductive success in adulthood, alloparenting behaviors are actually high in juveniles as well...

Women and men differ in their risk for developing stress-related conditions such as alcohol use and anxiety disorders and there are gender differences in the typical sequence in which these disorders co-occur. However, the neural systems underlying these gender-biased psychopathologies and clinical course modifiers in humans are poorly understood and may involve both central and peripheral mechanisms regulating the limbic-hypothalamic-pituitary-adrenal axis. In the present randomized, double blind, placebo-controlled, triple-dummy crossover study, we juxtaposed a centrally-acting, citalopram (2 mg/unit BMI) neuroendocrine stimulation test with a peripherally-acting, dexamethasone (Dex) (1...

Presacral myelolipomas are rare, benign, asymptomatic tumors composed of mature adipose tissue and hematopoietic elements. Presacral myelolipomas can occur in patients with a medical history of malignancy, steroid use, and/or endocrine disorders including diabetes mellitus. A 65-year-old man with no specific medical history experienced temporal abdominal pain without bowel symptoms that lasted a few hours. By the time he visited a hospital, the pain had diminished. Computed tomography failed to detect any abnormality in the abdominal or pelvic organs that would have caused the abdominal pain but revealed a lesion 4 cm in diameter in the frontal sacrum...

REVIEW

Unlike other essential trace elements that interact with proteins in the form of cofactors, selenium (Se) becomes co-translationally incorporated into the polypeptide chain as part of 21st naturally occurring amino acid, selenocysteine (Sec), encoded by the UGA codon. Any protein that includes Sec in its polypeptide chain is defined as selenoprotein. Members of the selenoproteins family exert various functions and their synthesis depends on specific cofactors and on dietary Se. The Se intake in productive animals such as chickens affect nutrient utilization, production performances, antioxidative status and responses of the immune system...

REVIEW
Ryan W England, Eliza B Geer, Amy R Deipolyi
Venous sampling is the gold standard for localizing abnormal hormone secretion in several endocrine disorders. The most common indication for venous sampling is in the workup of primary aldosteronism, adrenocorticotropic hormone-dependent Cushing's syndrome, and hyperparathyroidism. In experienced hands, venous sampling is safe and accurate. This review discusses the role of venous sampling in the workup of endocrine disease, describing the underlying anatomy and pathophysiology, as an understanding of these concepts is essential for technical and clinical success...

Bis-phenols, such as bis-phenol A (BPA) and bis-phenol-S (BPS), are polymerizing agents widely used in the production of plastics and numerous everyday products. They are classified as endocrine disrupting compounds (EDC) with estradiol-like properties. Long-term exposure to EDCs, even at low doses, has been linked with various health defects including cancer, behavioral disorders, and infertility, with greater vulnerability during early developmental periods. To study the effects of BPA on the development of neuronal function, we used an in vitro neuronal network derived from the early chick embryonic brain as a model...

Phthalates are chemical compounds classified as endocrine disruptors which are present in practically every environment of daily life. In the field of artificial nutrition, they are relevant because they are found as plasticizers in infusion lines made with PVC. They are lipophilic molecules which weakly pair with PVC and, therefore, they are easily extracted by the fatty compounds that are part of both the parenteral and enteral nutrition, as various studies show. As endocrine disruptors, they directly affect the reproductive organs because of their antiandrogenic and estrogenic effects...

The latter half of the twentieth century has witnessed a humongous spurt in the use of synthetic chemicals in a wide variety of industrial and agricultural applications are leading to niche specific perturbations affecting every trophic level of the ecosystems due to unmitigated environmental contamination. Despite the incremental usefulness of endocrine disrupting chemicals (EDCs) such as pesticides and plasticizers, their statutory impact on environmental health is assuming worrisome proportions. The EDCs can disrupt physiological homeostasis resulting in developmental and reproductive abnormalities...
