Purpose Transition from pediatric to adult care is associated with significant challenges in patients with Turner syndrome (TS). The objective of the TRansition Age Management In Turner syndrome in Italy (TRAMITI) project was to improve the care provided to patients with TS by harnessing the knowledge and expertise of various Italian centers through a Delphi-like consensus process. Methods A panel of 15 physicians and 1 psychologist discussed 4 key domains: transition and referral, sexual and bone health and oncological risks, social and psychological aspects and systemic and metabolic disorders. Results A total of 41 consensus statements were drafted. The transition from pediatric to adult care is a critical period for patients with TS, necessitating tailored approaches and early disclosure of the diagnosis to promote self-reliance and healthcare autonomy. Fertility preservation and bone health strategies are recommended to mitigate long-term complications, and psychiatric evaluations are recommended to address the increased prevalence of anxiety and depression. The consensus also addresses the heightened risk of metabolic, cardiovascular and autoimmune disorders in patients with TS; regular screenings and interventions are advised to manage these conditions effectively. In addition, cardiac abnormalities, including aortic dissections, require regular monitoring and early surgical intervention if certain criteria are met. Conclusions The TRAMITI consensus statement provides valuable insights and evidence-based recommendations to guide healthcare practitioners in delivering comprehensive and patient-centered care for patients with TS. By addressing the complex medical and psychosocial aspects of the condition, this consensus aims to enhance TS management and improve the overall well-being and long-term outcomes of these individuals. Plain language summary The TRansition Age Management in Turner syndrome in Italy (TRAMITI) project aims to improve care for individuals with Turner Syndrome (TS) during their transition from pediatric to adult care. A team of 15 physicians and 1 psychologist collaborated to create a comprehensive set of 41 consensus statements, covering four key areas: transition and referral, sexual and bone health and oncological risks, social and psychological aspects and systemic and metabolic disorders. The consensus statements highlight the importance of patient-centered care, early intervention and long-term monitoring. They emphasize a multidisciplinary approach to address the complex medical and psychosocial aspects of TS. During the critical transition period, tailored approaches and early disclosure of the diagnosis are recommended to promote self-reliance and healthcare autonomy. To mitigate long-term complications, the consensus addresses fertility preservation and bone health strategies. It also recommends psychological or psychiatric evaluations to tackle the increased prevalence of anxiety and depression in patients with TS. In addition, strategies for addressing the heightened risk of metabolic, cardiovascular and autoimmune disorders in patients with TS are proposed. Regular screenings and interventions are advised to effectively manage these conditions. Furthermore, cardiac abnormalities, including aortic dissections, require close monitoring and early surgical intervention if specific criteria are met. Overall, the TRAMITI consensus statement provides valuable insights and evidence-based recommendations. It offers guidance for healthcare practitioners in delivering comprehensive and patient-centered care for individuals with TS. By addressing both medical and psychosocial aspects, the consensus aims to enhance TS management and improve the well-being and long-term outcomes of those affected by this genetic disorder.

Knowledge is limited about prognostic significance of breast cancer subtypes among women with small invasive node-negative breast tumours. We explored patterns of recurrence in 1691 women with pT1mic/T1a/T1b, pN0 and M0 breast cancer according to four immunohistochemically defined tumour subtypes: (i) Luminal A (ER-positive, PgR-positive, HER2-negative and Ki-67 < 14%); (ii) Luminal B (ER-positive and/or PgR-positive, HER2-positive and/or Ki-67 ≥ 14%); (iii) HER2-positive, both endocrine receptors absent; and (iv) Triple Negative. At multivariate analysis, women with the Triple Negative breast cancer subtype had an increased risk of loco-regional relapse (LRR) (Hazards Ratio (HR) 3.58; 95%CI: 1.40–9.13) and breast cancer related events (HR 2.18; 95%CI: 1.04–4.57). Overall, Luminal B subtype was not associated with a statistically significant increased risk of recurrence compared with Luminal A, while patients with Luminal B subtype tumours overexpressing HER2 had a 2 fold risk of reduced breast cancer related survival (BCS), but not an increased risk of LRR and distant metastases. Women with HER2 breast cancer subtype had a statistically significant increased risk of LRR (HR 4.53; 95%CI: 1.56–13.1), distant metastases and reduced BCS (HR 3.22; 95%CI: 1.44–7.18) and overall survival (HR 2.87; 95%CI: 1.05–7.89) when compared with the Luminal A subtype, at multivariate analysis. In conclusion, women with small size, node-negative, breast cancer are at higher risk of relapse if with HER2-positive endocrine receptor absent or Triple Negative disease.

Farnesylated prelamin A is a processing intermediate produced in the lamin A maturation pathway. Accumulation of a truncated farnesylated prelamin A form, called progerin, is a hallmark of the severe premature ageing syndrome, Hutchinson-Gilford progeria. Progerin elicits toxic effects in cells, leading to chromatin damage and cellular senescence and ultimately causes skin and endothelial defects, bone resorption, lipodystrophy and accelerated ageing. Knowledge of the mechanism underlying prelamin A turnover is critical for the development of clinically effective protein inhibitors that can avoid accumulation to toxic levels without impairing lamin A/C expression, which is essential for normal biological functions. Little is known about specific molecules that may target farnesylated prelamin A to elicit protein degradation. Here, we report the discovery of rapamycin as a novel inhibitor of progerin, which dramatically and selectively decreases protein levels through a mechanism involving autophagic degradation. Rapamycin treatment of progeria cells lowers progerin, as well as wild-type prelamin A levels, and rescues the chromatin phenotype of cultured fibroblasts, including histone methylation status and BAF and LAP2alpha distribution patterns. Importantly, rapamycin treatment does not affect lamin C protein levels, but increases the relative expression of the prelamin A endoprotease ZMPSTE24. Thus, rapamycin, an antibiotic belonging to the class of macrolides, previously found to increase longevity in mouse models, can serve as a therapeutic tool, to eliminate progerin, avoid farnesylated prelamin A accumulation, and restore chromatin dynamics in progeroid laminopathies.

Purpose 25OHD levels in patients with Prader-Willi Syndrome (PWS), the most frequent cause of genetic obesity with a peculiar fat mass distribution, are still debated. Insulin resistance (IR), Body Mass Index-SDS (BMI-SDS), Growth Hormone Therapy (GHT), and puberty onset seem to interact with 25OHD levels. The objectives of the study are: (1) To analyze 25OHD levels in pediatric PWS patients in comparison with a control group (CNT) (2) To evaluate a possible correlation between BMI-SDS, HOMA-IR, puberty, GHT, and 25OHD levels. Methods This is a retrospective case–control, multicenter study. Data were collected among 8 different Italian Hospitals (outpatient clinics), over a period of four years (2016–2020). We included 192 genetically confirmed PWS and 192 CNT patients, aged 3–18 years, matched 1:1 for age, gender, BMI-SDS, Tanner stage, sun exposure, and month of recruitment. Results No statistically significant differences in 25OHD levels were observed between the PWS population and the CNT (PWS 24.0 ng/mL vs CNT 22.5 ng/mL, p  > 0.05), OR = 0.89 (95% CI 0.58–1.35). We observed a slight, although non-significant, reduction in 25OHD levels comparing NW and OB populations. HOMA-IR, puberty onset, genotype and GHT (previous or ongoing) did not show statistically significant correlation with 25OHD levels. Conclusions Our findings could be useful for clinicians to optimize the therapeutic management as well as to increase awareness of PWS.

A más de un siglo de su publicación en diferentes periódicos en lengua española y en volúmenes antológicos en prosa que aún hoy siguen siendo poco estudiados en los estudios críticos sobre el género, las crónicas europeas de Rubén Darío invitan a ser revisitadas, en la medida en que ofrecen un vasto repertorio de cuestiones y curiosidades, siempre abierto a nuevas lecturas y reflexiones. En este trabajo, nos interesa detenernos en un corpus de crónicas cosmopolitas, en las que el prolífico cronista-poeta selecciona objetos, prácticas y procesos, devenido “ciudadano de Cosmópolis” -como se autorretrata en Peregrinaciones (1901)-, y los registra en sus textos periodísticos, a partir de 1900, a lo largo de su desplazamiento por distintos escenarios de la modernidad-mundo. Entre las cuestiones que lo ocupan, destacamos algunas que requieren un abordaje más abarcador que exceda lo meramente temático, tales como la construcción de una subjetividad moderna, la representación de escenas cosmopolitas, la intervención del cronista como gestor cultural, la estetización de materiales procedentes de otros órdenes no artísticos.

The pathogenesis of otitis media is related to Eustachian tube dysfunction. The tensor veli palatini muscle actively opens the Eustachian tube and promotes middle-ear ventilation. This study describes a technique for paratubal electromyography that uses a surface, non-invasive electrode able to record tensor veli palatini muscle activity during swallowing. Twenty otitis media patients and 10 healthy patients underwent tensor veli palatini electromyography. Activity of this muscle before and after Eustachian tube rehabilitation was also assessed. In 78.5 per cent of patients, the electromyography duration phase and/or amplitude were reduced in the affected side. The muscle action potential was impaired in all patients who underwent Eustachian tube rehabilitation. This study confirmed that Eustachian tube muscle dysfunction has a role in otitis media pathogenesis and showed that muscle activity increases after Eustachian tube rehabilitation therapy.

The antiangiogenic agent bevacizumab showed synergistic effects when combined with chemotherapy in advanced breast cancer. We presently investigated the activity of bevacizumab in combination with chemotherapy, including capecitabine and vinorelbine, and endocrine therapy, including letrozole (+triptorelin in premenopausal women), as primary therapy for patients with ER and/or PgR ⩾10% T2–T4a-c, N0–N2, M0 breast cancer. Biological end point included the proliferative activity (Ki67), whereas clinical end points were clinical response rate, pathological complete response (pCR) and tolerability. Circulating endothelial cells (CECs) and their progenitors, as surrogate markers of antiangiogenic activity, were measured at baseline and at surgery.Thirty-six women are evaluable. A clinical response rate of 86% (95% CI, 70–95) and no pCR were observed; Ki67 was significantly decreased by 71% (interquartile range, −82%, −62%). Toxicity was manageable: two grade 3 hypertension, four grade 3 deep venous thrombosis and no grade >2 proteinuria were observed. Treatment significantly decreased the percentage of viable CECs and prevented the chemotherapy-induced mobilisation of circulating progenitors. Basal circulating progenitors were positively associated with clinical response. In conclusion, bevacizumab is feasible and active in association with primary chemoendocrine therapy for ER-positive tumours in terms of proliferation inhibition, clinical response and antiangiogenic activity.

Locally advanced breast cancer (LABC) is associated with dire prognosis despite progress in multimodal treatments. We evaluated several clinical and pathological features of patients with either noninflammatory (NIBC, cT4a-c) or inflammatory (IBC, cT4d) breast cancer to identify subset groups of patients with high risk of early treatment failure. Clinical and pathological features of 248 patients with LABC, who were treated with multimodality treatments including neoadjuvant chemotherapy followed by radical surgery and radiotherapy were reassessed. Tumour samples obtained at surgery were evaluated using standard immunohistochemical methods. Overall, 141 patients (57%) presented with NIBC (cT4a-c, N0-2, M0) and 107 patients (43%) with IBC (cT4d, N0-2, M0). Median follow-up time was 27.5 months (range: 1.6–87.8). No significant difference in terms of recurrence-free survival (RFS) ( P =0.72), disease-free survival (DFS) ( P =0.98) and overall survival (OS) ( P =0.35) was observed between NIBC and IBC. At the multivariate analysis, patients with ER- and PgR-negative diseases had a significantly worse RFS than patients with ER- and/or PgR-positive diseases (hazard ratio: 2.47, 95% CI: 1.33–4.59 for overall). The worst RFS was observed for the subgroup of patients with endocrine nonresponsive and HER2-negative breast cancer (2-year RFS: 57% in NIBC and 57% in IBC) A high Ki-67 labelling index (>20% of the invasive tumour cells) and the presence of peritumoral vascular invasion (PVI) significantly correlated with poorer RFS in overall (HR 2.69, 95% CI: 1.61–4.50 for Ki-67>20% and HR 2.27, 95% CI: 1.42–3.62 for PVI). Patients with endocrine nonresponsive LABC had the most dire treatment outcome. High degree of Ki-67 staining and presence of PVI were also indicators of higher risk of early relapse. These factors should be considered in therapeutic algorithms for LABC.
