Background: The pandemic of new severe acute respiratory syndrome (SARS) due to coronavirus (CoV) 2 (SARS-CoV-2) has stressed the importance of effective diagnostic and prognostic biomarkers of clinical worsening and mortality. Epidemiological data showing a differential impact of SARS-CoV-2 infection on women and men have suggested a potential role for testosterone (T) in determining gender disparity in the SARS-CoV-2 clinical outcomes. Objectives: To estimate the association between T level and SARS-CoV-2 clinical outcomes (defined as conditions requiring transfer to higher or lower intensity of care or death) in a cohort of patients admitted in the respiratory intensive care unit (RICU). Materials and methods: A consecutive series of 31 male patients affected by SARS-CoV-2 pneumonia and recovered in the respiratory intensive care unit (RICU) of the "Carlo Poma" Hospital in Mantua were analyzed. Several biochemical risk factors (ie, blood count and leukocyte formula, C-reactive protein (CRP), procalcitonin (PCT), lactate dehydrogenase (LDH), ferritin, D-dimer, fibrinogen, interleukin 6 (IL-6)) as well as total testosterone (TT), calculated free T (cFT), sex hormone-binding globulin (SHBG), and luteinizing hormone (LH) were determined. Results: Lower TT and cFT were found in the transferred to ICU/deceased in RICU group vs groups of patients transferred to IM or maintained in the RICU in stable condition. Both TT and cFT showed a negative significant correlation with biochemical risk factors (ie, the neutrophil count, LDH, and PCT) but a positive association with the lymphocyte count. Likewise, TT was also negatively associated with CRP and ferritin levels. A steep increase in both ICU transfer and mortality risk was observed in men with TT < 5 nmol/L or cFT < 100 pmol/L.

These results suggest that lymphocytic infiltration of HT is a protective factor against PTC progression, and it is independent of BRAF mutational status.

Sexual function worsens with advancing menopause status. The most frequently reported symptoms include low sexual desire (40-55%), poor lubrication (25-30%) and dyspareunia (12-45%), one of the complications of genitourinary syndrome of menopause (GSM). Declining levels of sex steroids (estrogens and androgens) play a major role in the impairment of sexual response; however, psychological and relational changes related with aging and an increase in metabolic and cardiovascular comorbidities should also be taken into account. Although first-line therapeutic strategies for menopause-related sexual dysfunction aim at addressing modifiable factors, many hormonal and non-hormonal, local and systemic treatment options are currently available. Treatment should be individualized, taking into account the severity of symptoms, potential adverse effects and personal preferences.

Objective To assess the safety and efficacy of convalescent plasma (CP) transfusion in elderly people with moderate to severe COVID-19 living in a long-term care facility (LTCF). Patients and Methods Twenty-two consecutive elderly COVID-19 patients living in a LTCF in Lombardy (Italy) who were given CP during the period May 15-July 31, 2020 were enrolled in a prospective cohort study. Their clinical, instrumental and laboratory parameters were assessed following the CP treatment. Overall mortality rate in this group was compared with that recorded in other LCTF in Lombardy during the 3-month period from March-May 2020. Results Of the 22 patients enrolled, 68.2% (n=15) received one CP unit, 27.3% (n=6) received two units and 4.5% (n=1) received three units. Of the CP units transfused, 76.7% (23/30) had a neutralizing antibody titer ≥1:160. No adverse reactions were recorded during or after CP administration. Improvements of clinical, functional, radiological and laboratory parameters during the 14 days following CP transfusion were observed in all 19 patients who survived. Viral clearance was achieved in all patients by the end of follow-up (median 66 days, IQR 48-80 days). The overall mortality rate was 13.6% (3/22), which compared favorably with that in the control group (38.3%, 281/733, P=0.02) and corresponded to a 65% reduction of mortality risk. Conclusion Early administration of CP with an adequate anti-SARS-CoV-2 antibody-titer to elderly, symptomatic, COVID-19 patients in a LTCF was safe and effective in eliminating the virus, restoring patients’ immunity and blocking the progression of COVID-19, thereby improving patients’ survival.

Detection of BRAF mutation in cytology specimens has been proposed as a diagnostic adjunctive tool in evaluation of thyroid nodules with indeterminate cytology findings. Concurrent papillary thyroid carcinoma and Hashimoto's thyroiditis (HT), a disease characterized by thyroid lymphocytic infiltration, is a frequent occurrence. A large lymphocytic infiltrate might reduce the sensitivity of methods employed to detect BRAF mutation in thyroid cytology specimens. To determine whether testing for BRAF mutational status in fine needle aspirates (FNA) is reliable also in the presence of HT lymphocytic infiltration, we assessed the BRAF status by direct sequencing and pyrosequencing in a series of FNAs with and without concomitant HT lymphocytic infiltration. We also performed the same assessment by pyrosequencing in the corresponding tissue samples. Pyrosequencing demonstrated to be more sensitive than direct sequencing. The percentage of mutant BRAF(V600E) alleles was higher in FNAs than in the corresponding tissues, probably because of the lower stromal contamination in FNA than in the sections. In the presence of lymphocytic infiltration, the percentage of mutant BRAF(V600E) alleles determined by pyrosequencing was higher in FNAs than in the corresponding tissue samples (P < 0.0001), indicating a minor lymphocytic contamination in FNA. The diagnostic value of BRAF(V600E) in inconclusive FNAs was not hampered by thyroid lymphocytic infiltration. These results indicate that BRAF(V600E) assessment by pyrosequencing is a reliable assay useful to refine inconclusive cytology of thyroid nodules also in the presence of concurrent HT.

PCOS is one of the most common endocrine disorders and NAFLD is one of its most dangerous metabolic consequences. The diagnosis of NAFLD is not a practical task and the condition is at risk of being overlooked. The use of simpler but still reliable surrogate markers is necessary to identify women with a high likelihood of NAFLD. The aim of this study was to evaluate the clinical correlates of NAFLD Liver Fat Score (NAFLD-LFS) in women with oligomenorrhea and/or hirsutism. Furthermore, the study aimed to evaluate whether, among the hormonal parameters evaluated in such women, possible hallmarks of NAFLD may be identified. To this purpose, 66 women who attended our Outpatient Clinic for oligomenorrhea and/or hyperandrogenism were included in the study. In order to validate the results obtained in the first cohort, a second independent sample of 233 women evaluated for female sexual dysfunction (FSD) was analyzed. In cohort 1, NAFLD-LFS positively correlated with metabolic and inflammatory parameters. Among the hormone parameters, NAFLD-LFS showed no significant relationships with androgens but a significant negative correlation with SHBG (p&lt;0.0001) that therefore appeared as a candidate hallmark for pathologic NAFLD-LFS. The ROC analysis showed a significant accuracy (81.1%, C.I.69.1-93.0, p &lt;0.0001) for SHBG in identifying women with a pathological NAFLD-LFS. In particular, a SHBG 33.4 nmol/l was recognized as the best threshold, with a sensitivity of 73.3% and a specificity of 70.7%. In order to validate this SHBG as a marker of metabolic impairment possible related with the presence of NAFLD, we tested this threshold in cohort 2. FSD women with SHBG &lt;33.4 nmol/l had worse metabolic parameters than women with SHBG ≥33.4 nmol/l and a significantly higher NAFLD-LFS even after adjusting for confounders (B=4.18 [2.05; 6.31], p=0.001). In conclusion, this study provides a new evidence in the diagnostic process of NAFLD, showing that the measurement of SHBG, which is routinely assessed in the workup of women referred for possible PCOS, could identify women at higher metabolic risk, thus detecting those who may deserve further targeted diagnostic assessment.

SUMMARYAmong the metastases to thyroid gland, metastases from renal cell carcinoma (RCC) are not rare and their frequent macroscopic looks are similar to primary thyroid tumours. We report an unusual case of thyroid metastases from renal carcinoma in a 72 -year-old man presented with a 1-year history of choking spells, stridor and dyspnoea. Patient underwent right nephrectomy for RCC, 24 years ago. In the present case, a right hemithyroidectomy was performed for a suspected anaplastic thyroid carcinoma. Histological examination showed a metastases of a clear cell renal carcinoma. Although the RCC showed an indolent biological behaviour, the late thyroid metastases have concurred with a poor prognosis and the patient died 5 months after surgery. The interest of this case lies in the long progression-free survival of the RCC preceded by the diagnosis of the thyroid nodule and the discrepancy between the clinical-radiological and the histological assessment.
