Importance of Sexual Function Assessment in Multidimensional Evaluation of AGHD Patients: Results from the MAGHD Study.

Background: Adult growth hormone deficiency (AGHD) is a debilitating clinical condition leading to decreased quality of life (QoL). The impact of reduced muscle mass, weakening and loss of vitality on QoL have been well characterized in AGHD. The impact of AGHD on sexual function, a recognized factor able to modify well-being, has never been investigated. Aim: To investigate the prevalence of sexual dysfunction in AGHD patients referring to a single endocrinological center and grouped according to their his- tory of r-hGH therapy.Methods: The Management of Adult Growth Hormone Deficiency (MAGHD) Study is a pro- spective, real-life trial aiming to improve management of AGHD patients through a smartphone app (MAGHD App)and a wearable device. The 83 AGHD enrolled patients (31 Females, 52 Males, mean age 56.27 + 14.68 years) were divided in 3 groups (G) according to r-hGH therapy: on long-term r-hGH therapy (G1, n=32), previously treated with r-hGH (G2, n=20), never treated (G3, n=31). Within the first phase of the study, a large database was created collecting clinical, biochemical and psychological data. In addition to QLS-H and QoL-AGHDA routinely used to as- sess QoL, IIEF-15 and FSFI were employed to evaluate sexual function in males and females, respectively. The nonparametric Kruskal-Wallis test was used for compar- ison among 3 groups.Results: Here only baseline data of the MAGHD Study are presented.According to IIEF-15 results, the prevalence of erectile dysfunction (ED) in male AGHD cohort was 60%. Erectile function (EF) score was signifi- cantly higher in G1 compared to both G2 and G3 (p < 0.05) with an ED prevalence of 35% in G1, 75% in G2 and 75% in G3. Even excluding patients with serum testosterone lower than 2 ng/ml and older than 65 years, ED prevalence did not change significantly in the 3 groups. Moreover, EF do- main was inversely and directly correlated to age (R20.130, β-0.360) and IGF1 levels (R20.156, β0.395), respectively. The prevalence of female sexual dysfunction according to FSFI was 89.3%. Even though desire, arousal, lubrication and overall scores were significantly higher (better results) in G1 compared to G2 and G3 (p < 0.05), no correlation resulted between FSFI domains and IGF1 levels. Instead an inverse correlation resulted between desire domain and age.Conclusions: This study, performed in a real-life clinical setting, demonstrates a high prevalence of sexual dysfunc- tion in AGHD patients and that r-hGH treatment seems to be associated to better sexual outcomes. These results suggest that the evaluation of sexual function should be in- tegrated in the global assessment of AGHD patients since sexual activity is a fundamental domain able to influence both well-being and QoL

Effect of a standard schema of self-monitoring blood glucose in patients with poorly controlled, non-insulin-treated type 2 diabetes mellitus: A controlled longitudinal study

The effect of self-monitoring of blood glucose (SMBG) on glycemic control with regard to non-insulintreated Type 2 diabetes mellitus (NIT-Type 2 DM) is still a controversial topic. Against this backdrop, we sought to compare the effect of a continuous short-term SMBG schema with as-usual treatment, based on changes in oral antidiabetic treatment in patients with poorly controlled Type 2 DM. We reviewed 492 NIT-Type 2 DM record charts, selecting 27 patients, with poor glycemic control, who were thought to self-monitor their blood glucose levels (SMBG group). We then compared them with 27 patients treated with modifying drugs or diets to achieve and maintain the glycemic target (Control Group). Haemoglobin A1c (HbA1c) and fasting plasma glucose (FPG) were evaluated at baseline, after 3 and 6 months. HbA1c values decreased after 3 and 6 months in the SMBG group (P < 0.001 on both occasions) and in the control group (P < 0.05 and P < 0.01, respectively), but without a significant difference between the two groups when compared at the same time. The FPG progressively decreased in both groups, reaching a significant difference in the SMBG group after 3 months and in the control group after 6 months, and without a significant difference between the two groups. The SMBG schema used in our study could be adopted for target groups before proceeding to the next therapeutic enhancement drug step, representing a useful tool that can help diabetic patients in raising awareness of and treating their disease

Low Serum Testosterone (T) Is Associated with Poor Health Status in Young to Middle-Aged Human Immunodeficiency Virus (HIV)-Infected Men.

BACKGROUND: The relationship between health status, defined by frailty and comorbidities, and serum T levels has been widely demonstrated in general population, while only one previous retrospective study has explored it in HIV-infected men1. AIM: To investigate the association between frailty and go- nadal status by assessing serum total T (TT) with Liquid Chromatography tandem Mass Spectrometry (LC-MS/MS) in a cohort of HIV-infected men. METHODS: Prospective, cross-sectional, observational study on HIV-infected men (age <50 years) with on- going Highly Active Antiretroviral Therapy. Serum TT was assessed by the gold standard ID-LC-MS/MS. Sex hormone-binding globulin (SHBG) was measured by chem- iluminescent immunoassay. Calculated free T (cFT) was obtained by Vermeulen equation. Multimorbidity was de- fined as at least 3 comorbid conditions, including: hyperten- sion, diabetes, cardiovascular disease, chronic obstructive pulmonary disease, chronic kidney disease, osteoporosis, chronic viral hepatitis and cancers. Frailty was calculated through the validated 37-item frailty index (FI)2. Patients with FI>0.21 were considered frail. Statistical ana- lysis: Mann-Whitney U test was used to compare contin- uous variables. Correlations were performed using linear regression models. RESULTS: 315 consecutive HIV-infected men were enrolled (mean age 45.3\ub15.3 years; average duration of HIV-infection 16.3\ub18.8 years). 128 patients (40.5%) were co- morbid and 207 (64.9%) were frail. Either cFT (p=0.001) or TT (p<0.001) were lower in comorbid patients than others. FT was inversely related to the number of comorbidities (p<0.001, R2=0.045). Accordingly, cFT (p=0.003) and TT (p<0.001) were significantly lower in frail patients.Frailty score was inversely correlated with cFT (p<0.001, R2=0.058), TT (p=0.041, R2=0.014) and SHBG (p=0.003, R2=0.029). However, after adjustment for age and duration of HIV-infection, cFT, TT and SHBG were excluded from the regression model. CONCLUSIONS: Low cFT and TT levels are associated with multimorbidity and poor health status in HIV infected men. The bidirectional nature of this relationship leads to the figuration of an intriguing vicious circle where T de- ficiency triggers the onset of comorbidities or, vice versa, poor health status induces hypogonadism. At the same time, notwithstanding the inverse relation between FT and frailty, it seems that other stronger predictive factors, and in particular the duration of infection, are involved in de- termining the health outcome in this clinical setting

Free testosterone (FT) is inversely related to frailty in human immunodeficiency virus (HIV)-infected men.

BACKGROUND HIV-infection is associated to several age-related comorbidities, such as a premature decline of serum testosterone (T). There is evidence about the relationship between health status, represented by frailty and comorbidities, and serum T levels in general population, while only one previous retrospective study investigated it in HIV-infected men. AIM To investigate the association between frailty and gonadal status by assessing serum total T (TT) with Liquid Chromatography tandem Mass Spectrometry (LC-MS/MS) in a cohort of HIV-infected men. METHODS Prospective, cross-sectional, observational study on HIV-infected men (age years) with ongoing Highly Active Antiretroviral Therapy (HAART). Serum TT was assessed by the gold standard ID- LC-MS/MS. Sex hormone-binding globulin (SHBG) was measured by chemiluminescent immunoassay. Free T (FT) was calculated by Vermeulen equation. Frailty was calculated through -items multimorbidity frailty index. Saca aa Parameters were not normally distributed and Mann- Whitney U test was used to compare continuous variables. Correlations were performed using linear regression models. RESULTS consecutive HIV-infected men were enrolled (mean age .. years; average duration of HIV-infection .. years). patients (.) had TT below ng/dL and patients (.) had calculated FT below pg/mL. Overall, patients (.) had T deficiency defined by low TT levels and/or low FT. patients (.) showed SHBG above the normal range (. nmol/L). Frailty score (p.), age (p.), duration of HIV-infection and of HAART (p.) significantly differed between eugonadic and hypogonadic patients, while no difference was found for BMI (p.). FT inversely correlated with frailty score (p., R.), while TT did not (p.). At stepwise multivariate regression analysis, FT showed an inverse relation with age (p.,R.), years of infection (-.,p.,R.) and years of HAART (-.,p.,R.), but not with frailty score and BMI of patients. CONCLUSIONS To the best of our knowledge, this is the first properly-designed prospective study aiming to investigate the relationship between general health status and gonadal function in a cohort of HIV-infected men. FT is inversely related to frailty score, suggesting an impairment of gonadal function in those patients affected by more multimorbidities in this setting as well as in general population. At the same time, the age of patient and the duration of HIV-infection seem to be more potent predictive factors for serum FT levels than frailty score. In clinical practice it is important to check for testosterone in these patients due to frequent alterations of SHBG

Are pre-miR-146a and PTTG1 associated with papillary thyroid cancer?

Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy, with a steadily increasing incidence in the last few decades worldwide. The predisposition to developing this carcinoma by the heterozygous state of rs2910164 within the precursor of the miR-146a has been reported, but recently not confirmed. Interestingly, on the same chromosome, almost 50\u200akb separate the pre-miR-146a from the pituitary tumor-transforming gene 1 (PTTG1), a proto-oncogene involved in several tumors, including thyroid cancers. In this study, we analyzed, using a case-control design, the genetic association between PTC and the genomic region encompassing pre-miR-146a rs2910164 and PTTG1 rs1862391 and rs2910202. We enrolled 307 affected patients and 206 healthy controls. The possible presence of thyroid nodules in controls was excluded by ultrasonography. All the cases were submitted to single-nucleotide polymorphism (SNP) genotyping of pre-miR-146a and PTTG1, and risk association analyses were carried out. The genotypic and allelic frequencies of pre-miR-146a rs2910164 were not statistically different in the patients and controls, and this SNP was not in linkage disequilibrium with the investigated PTTG1 SNPs. Consistently, meta-analyses, the first including all the affected cases published to date, did not confirm the previously reported association of the heterozygous CG genotype with PTC. The PTTG1 SNPs exhibited the same allelic frequency in the patients and controls and were not associated with the disease. In conclusion, in a well-selected Italian population, neither pre-miR-146a rs2910164 nor PTTG1 rs1862391 and rs2910202 were found to be associated with the risk of developing PTC
