Thalassemia is an inherited disease that causes the production of damaged hemoglobin chains. Patients are diagnosed with thalassemia major due to major clinical signs and deep anemia. This study aimed to examine the major thalassemia and psychosocial aspect of it, which is such an important issue, to serve as a roadmap for better handling these patients and to contribute to the literature. The method used in this study was narrative review. A literature review was conducted by searching the materials published in databases including Web of Science, PubMed, Scopus, and Google Scholar search engine from 2001 to 2020. Besides WHO website was searched. Thalassemia major damages the heart, liver, lungs and endocrine organs due to anemia and iron accumulation. In addition, the patient may experience mental and social problems due to the congenital nature of the disease and its lifelong duration. The psychosocial problems and treatment burdens of thalassemia patients are very high. There are many studies about the prevalence and physical consequences of thalassemia. However, there are not enough articles and researches describing the psychosocial effects of thalassemia on patients and what can be done about these effects. For this reason, this paper focuses on the process of thalassemia and the psychosocial problems it creates to contribute to the literature and to be a roadmap for better handling these patients.

Non-alcoholic steatohepatitis (NASH) is characterized by steatosis, lobular inflammation, and enlargement of the diameter of hepatocytes (ballooning hepatocytes), with or without fibrosis. It affects 20% of patients with non-alcoholic fatty liver disease (NAFLD). Due to liver dysfunction and the numerous metabolic changes that commonly accompany the condition (obesity, insulin resistance, type 2 diabetes, and metabolic syndrome), the secretion of organokines is modified, which may contribute to the pathogenesis or progression of the disease. In this sense, this study aimed to perform a review of the role of organokines in NASH. Thus, by combining descriptors such as NASH, organokines, oxidative stress, inflammation, insulin resistance, and dyslipidemia, a search was carried out in the EMBASE, MEDLINE-PubMed, and Cochrane databases of articles published in the last ten years. Insulin resistance, inflammation and mitochondrial dysfunction, fructose, and intestinal microbiota were factors identified as participating in the genesis and progression of NASH. Changes in the pattern of organokines secretion (adipokines, myokines, hepatokines, and osteokines) directly or indirectly contribute to aggravating the condition or compromise homeostasis. Thus, further studies involving skeletal muscle, adipose, bone, and liver tissue as endocrine organs are essential to better understand the modulation of organokines involved in the pathogenesis of NASH to advance in the treatment of this disease.

Autoimmune polyendocrine syndrome type 1 (APS type 1) is a disease characterized by a variety of clinical manifestations resulting from the involvement of multiple endocrine and non-endocrine organs in the pathological process. APS type 1 is a rare genetically determined disease with autosomal recessive inheritance. Mutations in the autoimmune regulator gene (AIRE) lead to a disruption of the mechanism of normal antigen expression and the formation of abnormal clones of immune cells, and can cause autoimmune damage to organs. Within APS type 1, the most common disorders are primary adrenal insufficiency, hypoparathyroidism, and chronic candidiasis. Some understudied clinical manifestations of APS type 1 are autoimmune pathological processes in the eye: keratoconjunctivitis, dry eye syndrome, iridocyclitis, retinopathy, retinal detachment, and optic atrophy. This review presents the accumulated experimental and clinical data on the development of eye damage of autoimmune nature in APS type 1, as well as the laboratory and instrumental methods used for diagnosing the disease. Changes in the visual organs in combination with clinical manifestations of hypoparathyroidism, adrenal insufficiency and candidiasis should lead the clinical doctor to suspect the presence of APS type 1 and to examine the patient comprehensively. Timely genetic counselling will allow early identifi cation of the disease, timely prescription of appropriate treatment and prevention of severe complications.

Primary solitary fibrous tumor (SFT) of the thyroid gland is a rare mesenchymal tumor with fibroblastic differentiation, ramified, thin-walled, enlarged (staghorn) vessels and specific NAB2-STAT6 gene fusion, which is more commonly found in pleura and peritoneum. This neoplasm can be located in a variety of anatomical sites outside pleura and peritoneum including bone, visceral organs and soft tissues, head and neck examples representing only 10-15% of the extra-pleural and extra-peritoneal tumors. Diagnosing this entity can be difficult, especially in thyroid gland, mainly because of the rarity of this neoplasm, but presence of characteristic microscopic features together with positivity for STAT6 and CD34 can confirm the diagnosis and exclude other differential diagnosis. Information about the diagnosis and treatment options of thyroid SFTs is limited but almost all primary thyroid SFTs have a good prognosis and indolent clinical course. Clinical surveillance is still necessary because some SFTs can be aggressive. Raising awareness regarding extra-pleural and extra-peritoneal location of this tumor in endocrine organs can help to better manage these patients. We report the case of a 34-year-old female with primary SFT of the thyroid gland. Additionally, we review the literature for the main clinical, paraclinical and pathological features of this neoplasm.

Accurate control of innate behaviors associated with developmental transitions requires functional integration of hormonal and neural signals. Insect molting is regulated by a set of neuropeptides, which trigger periodic pulses in ecdysteroid hormone titers and coordinate shedding of the old cuticle during ecdysis. In the current study, we demonstrate that crustacean cardioactive peptide (CCAP), a structurally conserved neuropeptide described to induce the ecdysis motor program, also exhibits a previously unknown prothoracicostatic activity to regulate ecdysteroid production in the desert locust, Schistocerca gregaria. We identified the locust genes encoding the CCAP precursor and three G protein-coupled receptors that are activated by CCAP with EC50 values in the (sub)nanomolar range. Spatiotemporal expression profiles of the receptors revealed expression in the prothoracic glands, the endocrine organs where ecdysteroidogenesis occurs. RNAi-mediated knockdown of CCAP precursor or receptors resulted in significantly elevated transcript levels of several Halloween genes, which encode ecdysteroid biosynthesis enzymes, and in elevated ecdysteroid levels one day prior to ecdysis. Moreover, prothoracic gland explants exhibited decreased secretion of ecdysteroids in the presence of CCAP. Our results unequivocally identify CCAP as the first prothoracicostatic peptide discovered in a hemimetabolan species and reveal the existence of an intricate interplay between CCAP signaling and ecdysteroidogenesis.

Cellular senescence is considered a physiological process along with aging and has recently been reported to be involved in the pathogenesis of many age-related disorders. Cellular senescence was first found in human fibroblasts and gradually explored in many other organs, including endocrine organs. The adrenal cortex is essential for the maintenance of blood volume, carbohydrate metabolism, reaction to stress and the development of sexual characteristics. Recently, the adrenal cortex was reported to harbor some obvious age-dependent features. For instance, the circulating levels of aldosterone and adrenal androgen gradually descend, whereas those of cortisol increase with aging. The detailed mechanisms have remained unknown, but cellular senescence was considered to play an essential role in age-related changes of the adrenal cortex. Recent studies have demonstrated that the senescent phenotype of zona glomerulosa (ZG) acts in association with reduced aldosterone production in both physiological and pathological aldosterone-producing cells, whereas senescent cortical-producing cells seemed not to have a suppressed cortisol-producing ability. In addition, accumulated lipofuscin formation, telomere shortening and cellular atrophy in zona reticularis cells during aging may account for the age-dependent decline in adrenal androgen levels. In adrenocortical disorders, including both aldosterone-producing adenoma (APA) and cortisol-producing adenoma (CPA), different cellular subtypes of tumor cells presented divergent senescent phenotypes, whereby compact cells in both APA and CPA harbored more senescent phenotypes than clear cells. Autonomous cortisol production from CPA reinforced a local cellular senescence that was more severe than that in APA. Adrenocortical carcinoma (ACC) was also reported to harbor oncogene-induced senescence, which compensatorily follows carcinogenesis and tumor progress. Adrenocortical steroids can induce not only a local senescence but also a periphery senescence in many other tissues. Therefore, herein, we systemically review the recent advances related to cellular senescence in adrenocortical biology and its associated disorders.

The purpose of this paper is to study the distribution of the roles of medical staff in teams that provide medical care in a tertiary health care facility. Materials and methods. The study was conducted among medical workers of the Ukrainian Scientific and Practical Center for Endocrine Surgery, Transplantation of Endocrine Organs and Tissues of the Ministry of Health of Ukraine: Departments of Reproductive Medicine, Surgery and Consultative Clinic according to R. Belbin’s methodology for diagnosing team roles using BSPIQ uestionnaire (Belbin Self-Perception Inventory). The study involved 25 health workers from three structural units of the center: the Department of Reproductive Medicine (7 respondents), a consultative clinic of different specialties (11) and the Department of Endocrine Surgery (7). This study was conducted in several stages. In the first stage, respondents identified and assessed their role in the team based on self-assessment. Respondents answered «Yes» / «No» to 3 short questions concerning the knowledge about the distribution of team members according to the typology of roles proposed by R.M. Belbin (1); belief that the roles that employees perform in the department are identical to their positions or expectations; confidence in the definition of team roles by personality type (3). The following is the direct diagnosis and definition of team roles among the selected medical staff of this health care institution.The survey was conducted during COVID-19 pande­mic, so it has some sampling limitations and is a pilot study. Results and discussion. According to the survey, it was found that all respondents were not previously familiar with this methodology. Every second respondent does not believe in the identity of the roles that employees perform in these teams, their positions or descriptions. However, 84 % of respondents indicated the dependence of team roles on personality type. The results of respondents’ self-assessment of their own roles in teams and direct diagnosis of the distribution of roles using the BSPI-questionnaire coincided with only 5 % of respondents. According to the study, there was a statistically significant relationship between gender and team membership. In particular, only women work in team I (Department of Reproductive Medicine), and 91 % of men (p < 0.002) work in team III (Department of Endocrine Surgery). The situation is similar in terms of position and work in individual clinical teams studied (p < 0.001). The hypothesis of the existence of a relationship between the age of the respondent and the severity of his command role behavioral functions was not confirmed (p < 0.991).The teams differed statistically significantly in the filling of roles (p < 0.087). Separate regularities of distribution of roles in each of the studied commands are revealed. Conclusions. This study points to the importance of studying the distribution of roles in teams. According to its results, it was found that the team (behavioral) role (role) of a member of the studied teams depends on gender and position, but is not related to the age factor. Team roles in the studied clinical teams are distributed differently: the most pronounced role characteristics in all teams are a specialist (expert), a completer-finisher (controller); the absence of a coordinator role has been established. Roles such as monitor evaluator and resource investigator exist only in the team of doctors of the consulting clinic.

Sleep apnea syndrome (SAS) is a prevalent disorder characterized by recurrent apnea or hypoxia episodes leading to intermittent hypoxia (IH) and arousals during sleep. Currently, the relationship between SAS and metabolic diseases is being actively analyzed, and SAS is considered to be an independent risk factor for the development and progression of insulin resistance/type 2 diabetes (T2DM). Accumulating evidence suggests that the short cycles of decreased oxygen saturation and rapid reoxygenation, a typical feature of SAS, contribute to the development of glucose intolerance and insulin resistance. In addition to IH, several pathological conditions may also contribute to insulin resistance, including sympathetic nervous system hyperactivity, oxidative stress, vascular endothelial dysfunction, and the activation of inflammatory cytokines. However, the detailed mechanism by which IH induces insulin resistance in SAS patients has not been fully revealed. We have previously reported that IH stress may exacerbate insulin resistance/T2DM, especially in hepatocytes, adipocytes, and skeletal muscle cells, by causing abnormal cytokine expression/secretion from each cell. Adipose tissues, skeletal muscle, and the liver are the main endocrine organs producing hepatokines, adipokines, and myokines, respectively. In this review, we focus on the effect of IH on hepatokine, adipokine, and myokine expression.

Abstract This study was investigated the protective role of (CoQ10) on reproductive dysfunction of males quail induced by hydrogen peroxide (H2O2). Forty Japanese quail male 45 days old were randomly allotted into four groups with ten replicate one per each , and treated for 28 days as follows : (G1): the first control group (G2): reserved standard ratio and (1%) H2O2 in drinking water. (G3): reserved production ratio + (100 mg Co Q10/kg diet) and (1%) H2O2 in drinking water. (G4): reserved production ratio + (100 mg Co Q10/kg diet) and normal water. The results showed that exposure of birds to H2O2 caused decrease in serum glutathione level (GSH), testosterone, luteinizing hormones (LH) and follicle stimulating hormone (FSH) hormones and this reflects on histology of testis by reducing seminiferous tubules diameter , area of germinal layer and germinal layer thickness. Whereas supplement of CoQ10 caused an increase the concentrations of theses, hormones in-group G4 as compared with group G2. It can noted that an addition was able to restore the oxidative stress birds (G3) to a state close to the natural state (G1). Though testicular histological modifications were made strides in grown-up Japanese quail male treated with CoQ10. In conclusion, the comes about of the display think about appeared that utilize of Co Q10 can easing the pernicious impacts on male regenerative work takingafter introduction toH2O, maybe through enhancement the antioxidant parameters or testicular capacities or other related endocrine organs.

The musculoskeletal system consisting of bones and muscles have been recognized as endocrine organs secreting hormones that are involved in regulating metabolic and inflammatory pathways. Obesity and type 2 diabetes (T2D) are associated with several musculoskeletal system complications. We hypothesized that an interaction exists between adipomyokines namely, irisin and METRNL, and various molecules involved in bone remodeling in individuals with obesity and T2D. A total of 228 individuals were enrolled in this study, including 124 non-diabetic (ND) and 104 T2D. A Multiplex assay was used to assess the level of various osteogenic molecules namely osteoactivin, Syndecan, osteoprotegerin (OPG) and osteonectin/SPARC. Our data shows elevated levels of Osteoactivin, Syndecan, OPG and SPARC in T2D as compared to ND individuals (p ≤ 0.05). Using Spearman’s correlation, a positive correlation was observed between irisin and Osteoactivin as well as OPG (p &lt; 0.05). Similarly, a positive association was observed between METRNL and Osteoactivin (p &lt; 0.05). The strong positive association shown in this study between irisin, METRNL and various molecules with osteogenic properties emphasize a possible interaction between these organs. This report suggests that having a dysregulation in the level of the aforementioned molecules could potentially affect the development of bone and muscle related complications that are associated with obesity and T2D.
