ssignment surgery helps to reduce the level of suffering in transmen and transwomen. Satisfaction with life, mental and physical health as well as social life improve after surgical treatment combined with endocrinologic and psychological treatment. However, compared with the normal population, the quality of life of transsexual people lags behind.
DNA methylation-based epigenetic age measures have been used as biological aging markers and are associated with a healthy lifespan. Few population-based studies have examined the relation between diet and epigenetic age acceleration.
We aimed to investigate the relation between diet quality and epigenetic age acceleration.
We analyzed data from 1995 participants (mean age, 67 years; 55% women) of the Framingham Heart Study Offspring Cohort. Cross-sectional associations between the Dietary Approaches to Stop Hypertension (DASH) score and 3 whole-blood DNA methylation-derived epigenetic age acceleration measures-Dunedin Pace of Aging Methylation (DunedinPoAm), GrimAge acceleration (GrimAA), and PhenoAge acceleration (PhenoAA)-were examined. A mediation analysis was conducted to assess the mediating role of epigenetic age acceleration in relation to DASH and all-cause mortality.
A higher DASH score was associated with lower levels of DunedinPoAm (β = -0.05; SE=0.02; P=0.007), GrimAA (β = -0.09; SE=0.02;ality is associated with slower epigenetic age acceleration, which partially explains the beneficial effect of diet quality on the lifespan. Our findings emphasize that adopting a healthy diet is crucial for maintaining healthy aging.We analyzed 221 COVID-19 cases identified between June 2020 and January 2021 in 6,074 individuals screened for IgG antibodies in May 2020, representing 77% of residents of five Italian municipalities. The adjusted relative risk of developing symptomatic infection in SARS-COV-2 seropositive participants was 0.055 (95%CI 0.014 - 0.220).
Atrophic gastritis (AG) and use of proton pump inhibitors (PPIs) result in gastric acid suppression that can impair the absorption of vitamin B-12 from foods. The crystalline vitamin B-12 form, found in fortified foods, does not require gastric acid for its absorption and could thus be beneficial for older adults with hypochlorhydria, but evidence is lacking.
To investigate associations of AG and PPI use with vitamin B-12 status, and the potential protective role of fortified foods, in older adults.
Eligible participants (n = 3299) not using vitamin B-12 supplements were drawn from the Trinity-Ulster and Department of Agriculture cohort, a study of noninstitutionalized adults aged ≥60 y and recruited in 2008-2012. Vitamin B-12 status was measured using 4 biomarkers, and vitamin B-12 deficiency was defined as a combined indicator value <-0.5. A pepsinogen III ratio <3 was considered indicative of AG.
AG was identified in 15% of participants and associated with significantly lower serum total vitaof PPIs are more likely to have indicators of vitamin B-12 deficiency. Fortified foods, if consumed regularly, were associated with enhanced vitamin B-12 status, but higher levels of added vitamin B-12 than currently provided could be warranted to optimize status in people with AG.
Adaptive thermogenesis (AT) is currently defined as the fat-free mass (FFM)-independent change in resting energy expenditure (REE) in response to caloric restriction (CR) or overfeeding (OF). So far, the impact of changes in the anatomical and molecular composition of FFM on AT has not been addressed.
To assess the impact of changes in FFM composition on AT.
FFM was assessed in 32 healthy young men during controlled 21-d CR and 14 d of subsequent OF. Anatomical (i.e., the organ/tissue level) and molecular (i.e., water, mineral, and protein content and thus body density) composition of FFM were characterized. REE was measured by indirect calorimetry.
With CR, body weight and REE decreased by 4.2±0.9 kg and 173±107 kcal/d, respectively, with corresponding increases of 3.5±1.2 kg and 194±110 kcal/d during OF (P<0.001 for all changes). Changes in FFM explained 56.7% and 66.7% of weight loss and weight gain, respectively. Weight changes were associated with changes in various anatomical (i.e., masses ofl adjusted AT was likely not large enough in magnitude to be able to prevent weight loss or resist weight gain.Transitional hypoglycemia in normal newborns occurs in the first 3 days of life and has clinical features consistent with hyperinsulinism. We found a lower threshold for glucose-stimulated insulin secretion from freshly isolated embryonic day (E) 22 rat islets, which persisted into the first postnatal days. The threshold reached the adult level by postnatal day (P) 14. Culturing P14 islets also decreased the glucose threshold. Freshly isolated P1 rat islets had a lower threshold for insulin secretion in response to 2-aminobicyclo-(2, 2, 1)-heptane-2-carboxylic acid, a nonmetabolizable leucine analog, and diminished insulin release in response to tolbutamide, an inhibitor of β-cell KATP channels. These findings suggested that decreased KATP channel function could be responsible for the lower glucose threshold for insulin secretion. Single-cell transcriptomic analysis did not reveal a lower expression of KATP subunit genes in E22 compared with P14 β cells. The investigation of electrophysiological characteristics of dispersed β cells showed that early neonatal and cultured cells had fewer functional KATP channels per unit membrane area. Our findings suggest that decreased surface density of KATP channels may contribute to the observed differences in glucose threshold for insulin release.
Brucellosis is a severe, occupational or foodborne zoonosis throughout much of the world. Although eradicated from domestic cattle in the United States, brucellosis remains a disease risk to people through acquisition and consumption of animal products from endemic countries.
Cases of human brucellosis reported through the California public health disease surveillance network were reviewed for 1993 to 2017.
From 1993 to 2017, 492 cases of brucellosis were reported in residents of California. Persons aged ≥65 years represented less than 20% of cases, but incidence in this age group (0.94 cases per 10 6 population per year) was more than twice the incidence in persons aged ≤19 years (0.44). Incidence was 10 to 20 times greater among Latinos compared to non-Latinos across all age groups and both sexes. selleck kinase inhibitor Brucella melitensis was identified in 80% of patients for whom cultured Brucella were identified to species. Of 187 case-patients who reported consuming specifically unpasteurized dairy products, over 90% reported acquiring these products from outside the United States, most commonly from Mexico. In the latter half of the study period (2006-2017), 73% of Latino case-patients who reported consuming dairy products mentioned specifically consuming Mexican-style soft cheese ("queso fresco").
This study underscores the continuing serious health threat of brucellosis for Latinos in California, particularly older men, and the need for targeted public health messaging on preventing the risk presented by importation and consumption of unpasteurized dairy products from outside the United States, principally Mexico.

The recommendations for radioiodine therapy (RAIT) in metastatic differentiated thyroid cancer (DTC) are mostly based in the experience with papillary histotype and do not consider the differences within the distinct types of DTC, in terms of RAIT uptake and response.
To investigate the association between histology and RAIT avidity and response; to evaluate whether histotype was an independent prognostic factor in progression-free survival (PFS) and disease-specific survival (DSS) after RAIT for distant metastatic disease.
Retrospective analysis of all DTC patients submitted to RAIT due to distant metastatic disease, between 2001-2018.
Thyroid cancer referral centre.
We included 126 patients 42 (33.3%) classical variant papillary thyroid cancer (cvPTC), 45 (35.7%) follicular variant PTC (fvPTC), 17 (13.5%) follicular thyroid cancer (FTC) and 22 (17.5%) Hürthle-cell carcinoma.
RAIT avidity and response.
RAIT avidity was independently associated with histology (p<0.001) and stimulated thyroglobulin at first RAIT for distant lesions (p=0.007). Avidity was lowest in HCC (13.6%), intermediate in cvPTC (21.4%), and highest in fvPTC (75.6%) and FTC (76.5%). Regarding RAIT response, HCC and FTC were not different; both showed significantly more often progression after RAIT than fvPTC and cvPTC. Histology influenced PFS (p=0.014), but tumour type was not a significant prognostic factor in DSS. Instead, age at diagnosis, resection status, and stimulated thyroglobulin at the first RAIT were significantly associated with DSS.
DTC histotype influenced RAIT avidity and PFS. It is crucial to better detect the metastatic patients that may benefit the most from RAIT.

Measles outbreaks are reported worldwide posing a serious threat, especially to young unvaccinated infants. Early measles vaccination under 12 months of age can induce protective antibody levels, but the long-term antibody functionalities are unknown.
Measles-specific antibody-functionality was tested by systems serology, in children receiving an early measles vaccination at 6-8 or 9-12 months, followed by a regular dose at 14 months of age, and children only receiving the vaccination at 14 months. Antibody-functionalities comprised complement-deposition, cellular cytotoxicity, neutrophil and cellular phagocytosis. Pearson's r correlations between all effector functions were used to investigate the coordination of the response.
Children receiving early measles vaccination at 6-8 or 9-12 months show polyfunctional antibody responses. Despite significant lower levels of antibodies in these early-vaccinated children, Fc-effector functions were comparable with regular-timed vaccinees at 14 months. However, 3-year follow-up revealed significant decreased polyfunctionality in children that received a first vaccination at 6-8 months, but not in children that received the early vaccination at 9-12 months.
Antibodies elicited in early-vaccinated children are equally polyfunctional to those elicited from children who received vaccination at 14 months. However, these antibody-functionalities decays more rapidly than those induced later in life, which may lead to suboptimal long-term protection.
