Gynecomastia (GM) is benign unilateral or bilateral proliferation of the glandular tissue of breast in males. Its development during adolescence is usually considered a physiologic phenomenon and is expected to resolve within months. Sometimes however it is due to pathologic conditions or diseases and it is not uncommon these not to be recognized on time. The present study aims to investigate the causes of prepubertal and pathologic pubertal GM, its association with obesity, age of appearance and whether GM has a psychological impact on boys and adolescents admitted at endocrine department.

A total of 157 boys and adolescents with GM were included in a cross-sectional retrospective study in a single tertiary center for endocrine diseases. Patients were evaluated by anthropometric measurements, serum hormonal levels and a questionnaire.

For the period 2009-2018 a total of 157 boys and adolescents were diagnosed with GM (76.43 % obese, 3.18%- overweight). Twelve (7.64 %, mean age of GM development -7.53 yter the appearance of breast. So although greater number of pubertal GM is physiologic it may be reasonable adolescents to be evaluated within the first 6 months of breast development so not to delay the diagnosis of pathologic ones. Additionally we have found that GM has a complex influence on psychologic state of boys and adolescents.

Prepubertal and pubertal GM has a high association with obesity. Excess adipose tissue has an impact on the age of development in both groups. Nearly a quarter of pubertal cases are due to pathologic conditions and those are often diagnosed more than 18 months after the appearance of breast. So although greater number of pubertal GM is physiologic it may be reasonable adolescents to be evaluated within the first 6 months of breast development so not to delay the diagnosis of pathologic ones. Additionally we have found that GM has a complex influence on psychologic state of boys and adolescents.Arginine vasopressin (AVP), which is also called antidiuretic hormone (ADH), is a neurohormone synthetized from a pre-pro-hormone precursor in the supreoptic and paraventricular nuclei of the hypothalamus in response to increased plasma osmolality and decreased blood volume. AVP exerts a number of effects by binding to three different receptors - V1aR, V1bR and V2R. In recent years, it has been suggested that increased plasma concentration of AVP may play a causal role in the development of type 2 diabetes, the metabolic syndrome, renal dysfunction and cardiovascular disease by influencing glucose homeostasis and lipid metabolism through several possible mechanisms involving V1aR and V1bR. V1aR located in the liver is involved in hepatic glycogenolysis and gluconeogenesis. V1bR, found in the pituitary gland and pancreas mediates secretion of adrenocorticotrophic hormone (ACTH), insulin and glucagon. However, AVP's clinical use as a biomarker is limited due to its short half-life in plasma (16-20 minutes), small size and poor stability, which make direct measurement difficult. Copeptin, the biologically inactive, stable, C-terminal part of pro-vasopressin, is co-secreted with AVP in equimolar amounts and thus is considered an adequate and clinically useful surrogate marker of AVP. The aim of this review is to assess the current state of knowledge about the potential role of copeptin as a novel biomarker of the cardiometabolic syndrome on the basis of recent scientific literature published up to December 2020 and searches of the PubMed, Google Scholar, and Web of Science databases.

Identifying and managing patients with prediabetes is important. The study aims to investigate the association of body mass index (BMI) with impaired fasting glucose (IFG), β-cell dysfunction, and insulin resistance in nondiabetic Chinese individuals.

This was a cross-sectional study of consecutive nondiabetic individuals enrolled between January 2014 and January 2015, divided into the NFG (normal fasting glucose, fasting blood glucose [FBG] <5.6 mmol/L) and IFG (n=450; FBG ≥5.6 mmol/L) groups. Restricted cubic splines and piecewise-regression were used to model the association of IFG, impaired β-cell function, and insulin resistance with BMI. Stratified analyses were performed across sex and age.

A total of 900 NFG and 450 IFG individuals were enrolled, with a median age of 41 (30-49) years and 1076 males (79.7%). After adjusting for age and sex, the restricted cubic splines showed that the risk of IFG was increasing rapidly until around 27.96 kg/m2 of BMI and then started to flat afterward (P for non-linearity=0.010), which was similar in males and ≤45 years individuals (P for non-linearity<0.001 and =0.007, respectively). The risk of insulin resistance increased and β-cell dysfunction decreased as the BMI increased in all participants (both P for non-linearity>0.05), consistent with the results in males, females, and ≤45 and >45 years individuals.

The risk of IFG is not rising linearly as the BMI increases, and higher BMI seems to decelerate the rise of the risk.

Administration of testosterone or dehydroepiandrosterone to subjects with low levels of these hormones was found to reduce thyroid antibody titers. Male-pattern baldness is accompanied by mildly increased androgen levels. The present study was aimed at investigating whether early-onset androgenetic alopecia determines the impact of exogenous levothyroxine on thyroid autoimmunity and hypothalamic-pituitary-thyroid axis activity in young men with autoimmune hypothyroidism.

The study included two thyroid-antibody-matched groups of men with autoimmune hypothyroidism subjects with early-onset androgenetic alopecia (group 1; n=24) and subjects with no evidence of hair loss (group 2; n=24). https://www.selleckchem.com/products/ipi-549.html All patients were treated with exogenous levothyroxine. Circulating titers of thyroid peroxidase and thyroglobulin antibodies, as well as levels of thyrotropin, free thyroxine, free triiodothyronine, prolactin, total testosterone, calculated bioavailable testosterone, dehydroepiandrosterone-sulfate and estradiol were measuredenetic alopecia.When the temperature is increased, the heat-shock response is activated to protect the cellular environment. The transcriptomics and proteomics of this process are intensively studied, while information about how the cell responds structurally to heat stress is mostly lacking. Here, Saccharomyces cerevisiae were subjected to a mild continuous heat shock (38°C) and intermittently cryo-immobilised for electron microscopy. Through measuring changes in all distinguishable organelle numbers, sizes and morphologies in over 2100 electron micrographs, a major restructuring of the internal architecture of the cell during the progressive heat shock was revealed. The cell grew larger but most organelles within it expanded even more, shrinking the volume of the cytoplasm. Organelles responded to heat shock at different times, both in terms of size and number, and adaptations of the morphology of some organelles (such as the vacuole) were observed. Multivesicular bodies grew by almost 70%, indicating a previously unknown involvement in the heat-shock response. A previously undescribed electron-translucent structure accumulated close to the plasma membrane. This all-encompassing approach provides a detailed chronological progression of organelle adaptation throughout the cellular heat-stress response.Dermacentor variabilis is the most widely distributed three-host tick in North America, and transmits a variety of pathogens. Within the United States, this species has a discontinuous distribution, widespread east of the Rocky Mountains and with a few populations west of the Rockies. Phylogenetic evidence based on individual markers or relatively small data sets has suggested that populations at both sides of this geographic barrier may correspond to two different species. In this study, we further explore this hypothesis using an integrative taxonomy framework. Both molecular (mitochondrial and nuclear markers) and morphological analyses of specimens collected from central-eastern and western states were performed to explore species delimitation in this taxon. Results from these analyses were consistent, and provide strong evidence that D. variabilis actually corresponds to two species. Herein, the western populations are described as a new species, Dermacentor similis n. sp. The usefulness of integrative taxonomy in the context of species delimitation is also discussed.

Although diabetes mellitus (DM) was reported to be associated with incident colorectal cancer (CRC), the detailed association between fasting plasma glucose (FPG) and incident CRC has not been fully understood.

We assessed whether hyperglycemia is associated with a higher risk for CRC.

Analyses were conducted using the JMDC Claims Database [n = 1 441 311; median age (interquartile range), 46 (40-54) years; 56.6% men). None of the participants were taking antidiabetic medication or had a history of CRC, colorectal polyps, or inflammatory bowel disease. Participants were categorized as normal FPG (FPG level < 100 mg/dL; 1 125 647 individuals), normal-high FPG (FPG level = 100-109 mg/dL; 210 365 individuals), impaired fasting glucose (IFG; FPG level = 110-125 mg/dL; 74 836 individuals), and DM (FPG level ≥ 126 mg/dL; 30 463 individuals).

Over a mean follow-up of 1137 ± 824 days, 5566 CRC events occurred. After multivariable adjustment, the hazard ratios for CRC events were 1.10 (95% CI 1.03-1.18) for normal-high FPG, 1.24 (95% CI 1.13-1.37) for IFG, and 1.36 (95% CI 1.19-1.55) for DM vs normal FPG. We confirmed this association in sensitivity analyses excluding those with a follow-up of< 365 days and obese participants.

The risk of CRC increased with elevated FPG category. FPG measurements would help to identify people at high-risk for future CRC.

Spatial practices and changing urban environments affecting identity, experiences, and everyday life were examined among a diverse sample of older adults as they negotiated and navigated an age-friendly city.

Ethnographic interviews, observations, and visual methods were used to understand spatial practices and lived experiences of four older adults, who chronicled their lives using disposable cameras.

Informant identities emerged in their everyday practices, reflecting varied positionalities that fundamentally shaped their notions of "age-friendly." Informants sought to sustain or improve their lives while attempting to negotiate socio-environmental forms and forces that often threatened their identity and increased their precarity.

Contrast exists between "invariant" macro/meso issues all older adults face as they age and "multivariant" ways in which age is accomplished based on place, biography, and intersectionality. Age-friendly environments may simultaneously maintain the status quo and exacerbate inequalities.
