Background: Several US risk stratification score systems (RSSs) have been developed to standardize a thyroid nodule risk of malignancy. It is still a matter of debate which RSS is the most reliable. The purpose of this study is to evaluate: (1) the concordance between the American College of Radiology TI-RADS (ACR TI-RADS) and fine needle aspiration cytology (FNAC), (2) the cancer rate in the ACR TI-RADS categories, (3) the characteristics of nodules evaluated by FNAC even if not formally indicated according to ACR TI-RADS (‘not indicated FNACs”). Methods: From January 2021 to September 2022, patients attending the Endocrinology Unit of the CTO Hospital of Rome for evaluation of thyroid nodules were included. Results: 830 nodules had negative cytology, belonging to TIR2 and TIR1C. One hundred and thirteen nodules were determined to be suspicious for or consistent with malignancy belonging to TIR3B/TIR4/TIR5. Of this last group, 94% were classified as TR4/TR5 nodules. In total, 87/113 underwent surgery. Among these, 73 had histologically proven cancer, 14 turned out to be benign. “Not indicated FNACs” was 623. Among these, 42 cancers were present. Conclusions: This study confirmed the diagnostic power of ACR TI-RADS. In addition, these data suggest revising the ACR TI-RADS indication to FNAC, especially for TR4.

Background: The purpose of this study is to access whether a personal attitude to physical activity (PA) may influence the appearance of diabetic polyneuropathy (DPN) patients with well-controlled type 1 diabetes mellitus. Methods: Ninety patients attending the diabetes technology outpatient clinic were enrolled. DPN was investigated according to the Toronto consensus diagnostic criteria. PA was assessed using the International Physical Activity Questionnaire. Results: PA was low in 21.1%, moderate in 42.2% and high in 36.7% of patients. According to Toronto criteria, we defined two categories: the first one with DPN absent or possible (57 (63.3%)) and a second one with DPN certain or probable (33 (36.7%)). The χ²-test of the PA groups and the DPN categories showed a statistically significant difference (p < 0.001), with less neuropathy in patients belonging to the group of moderate/high PA. Exposure to a minimum of 600 MET minutes/week was protective factor against the onset of DPN (odd ratio 0.221, c.i. 0.068–0.720, p = 0.012). Conclusions: This study suggests that DPN is less present in type 1 diabetic patients with good metabolic control and a good personal habit of PA. Moderate-to-vigorous PA of at least 600 MET minutes/week might be a protective factor against DPN.

Background: Diabetes mellitus (DM) and osteoporosis are two of the most widespread metabolic diseases in the world. The aim of this study is to investigate the prevalence of DM among patients affected by osteoporosis and fragility fractures, and to search for differences in clinical characteristics. Methods: This is a single-center retrospective, case–controlled study. A total of 589 patients attending CTO Bone Unit between 2 January 2010 and 31 May 2023, due to osteoporosis and fragility fractures, were divided into two groups, according to the diagnosis of DM. The clinical and bone characteristics of patients were compared. Results: Prevalence of DM was 12.7%. Compared to patients without DM, the median age at the time of first fracture was similar: 72 years ± 13.5 interquartile range (IQR) vs. 71 years ± 12 IQR; prevalence of combination of vertebral and hip fractures was higher (p = 0.008), as well as prevalence of males (p = 0.016). Bone mineral density (BMD) at all sites was higher in DM group; trabecular bone score (TBS), instead, was significantly lower (p < 0.001). Conclusions: Patients with fragility fractures and DM more frequently show combination of major fractures with higher BMD levels. In these patients, TBS could be a better indicator of bone health than BMD and, therefore, might be used as a diagnostic tool in clinical practice.

Identifying preoperatively cases of more indolent papillary thyroid carcinoma (PTC)could be of high interest. The aim of this study was to verify previously published data on the prognostic value of fine needle aspiration cytology (FNAC)in PTC, also comparing findings from high-volume (HV)and low-volume (LV)institutions. From January 2022 to June 2024, the institutional database of the endocrinological surgery unit of Sant’Eugenio Hospital (Rome, Italy)was retrospectively reviewed to select patients who underwent thyroid surgery for PTC. To evaluate the prognostic value of presurgical FNAC, all histological features and the ATA risk of the study groups were compared. Later, data of patients entirely managed at our institution, considered as an HV institute, were compared with that of cases operated at our institution following FNAC performed LV centres.The 159 PTC nodules included were classified as TIR3B (20.1%),TIR4 (32.7%),and TIR5 (47.2%).The distribution of FNAC report between HV and LV was different (p = 0.01). The presence of lymph node metastasis (p = 0.004), and peri-thyroid tissue invasion (p = 0.02)increased according to the FNAC category. Significant difference among the three FNAC categories was also observed in PTC subtype (p = 0.006)and Hashimoto’s thyroiditis (p = 0.02).In addition, a significant different trend was found in ATA risk assessment, being the risk of recurrence more prevalent according to the FNAC category (p = 0.008). According to the second study aim, the higher prevalence of low-risk cases in TIR3B was confirmed in both HV (p = 0.04) and LV (p = 0.03)subgroups.PTCs with preoperative TIR3B have different histological features and ATA risk assessment with respect to cases with presurgical FNAC of TIR4/5.Particularly, PTC from TIR3B should have a pattern of more indolent cancers. As non-negligible extension, this data is not influenced by the institutional setting with high or low thyroid-FNAC volume.
