Abstract
Time-resolved optical spectroscopy represents an effective non-invasive approach to investigate the interplay of different degrees of freedom, which plays a key role in the development of novel functional materials. Here, we present magneto-acoustic data on Ni thin films on SiO2 as obtained by a versatile pump-probe setup that combines transient grating spectroscopy with time-resolved magnetic polarimetry. The possibility to easily switch from a pulsed to continuous wave probe allows probing of acoustic and magnetization dynamics on a broad time scale, in both transmission and reflection geometry.

Abstract
BACKGROUND About half of metastatic colorectal cancers (CRCs) harbor Rat Sarcoma (RAS) activating mutations as oncogenic driver, but the prognostic role of RAS mutations is not fully elucidated. Interestingly, specific hotspot mutations have been identified as potential candidates for novel targeted therapies in several malignancies as per G12C. This study aims at evaluating the association between KRAS hotspot mutations and patient characteristics, prognosis and response to antiangiogenic drugs. METHODS Data from RAS-mutated CRC patients referred to Careggi University Hospital, between January 2017 and April 2022 were retrospectively and prospectively collected. Tumor samples were assessed for RAS mutation status using MALDI-TOF Mass Spectrometry, Myriapod NGS-56G Onco Panel, or Myriapod NGS Cancer Panel DNA. RESULTS Among 1047 patients with available RAS mutational status, 183 KRAS-mutated patients with advanced CRC had adequate data for clinicopathological and survival analysis. KRAS mutations occurred at codon 12 in 67.2% of cases, codon 13 in 23.5%, codon 61 in 2.2%, and other codons in 8.2%. G12C mutation was identified in 7.1% of patients and exon 4 mutations in 7.1%. KRAS G12D mutation, as compared to other mutations, was significantly associated with liver metastases (1-sided p=0.005) and male sex (1-sided p=0.039), KRAS G12C mutation with peritoneal metastases (1-sided p=0.035), KRAS G12V mutation with female sex (1-sided p=0.025) and no surgery for primary tumor (1-sided p=0.005). No associations were observed between specific KRAS variants and age, ECOG PS, site of primary tumor, pattern of recurrence for resected patients, and lung, distant lymph node, bone, or brain metastases.Overall survival (OS) was significantly longer in patients with KRAS exon 4 mutations than in those with other KRAS mutations (mOS 43.6 months vs 20.6 months; HR 0.45 [0.21-0.99], p=0.04). No difference in survival was observed for mutations at codon 12/13/61 (p=0.1). Treatment with bevacizumab (BV) increased significatively mPFS (p=0.036) and mOS (p=0.019) of the entire population with a substantial benefit in mOS for G12V mutation (p=0.031). CONCLUSIONS Patterns of presentation and prognosis among patients with specific RAS hotspot mutations deserve to be extensively studied in large datasets, with a specific attention to the uncommon isoforms and the role of anti-angiogenic drugs.

Abstract
INTRODUCTION Acute supralevator abscess (SLA) is an uncommon and complicated form of anorectal sepsis. Its correct management is crucial to avoid complex iatrogenic fistula formation. A comprehensive review of the literature was conducted to determine the incidence of SLA and the surgical outcome with particular reference to the direction of drainage. METHODS A search of Medline, PubMed and the Cochrane Library was performed to identify all studies reporting surgical drainage of SLA. FINDINGS A total of 19 studies were identified, including 563 patients. The only two prospective studies reported an incidence of SLA of 10% and 3% in 68 and 100 patients, respectively, with anorectal sepsis. In 17 retrospective studies, the incidence ranged from 0% to 28%. Magnetic resonance imaging (MRI) was performed routinely in only one study. The surgical anatomical classification of the abscess was described in six studies diagnosed at surgery. The direction of surgical drainage whether 'inwards' (into the lumen) or 'outwards' (into the ischioanal fossa) was stated in only six studies. In two of these, the direction of drainage was contradictory to the recommendation made by Parks et al. Recurrent sepsis was reported in eight studies and ranged from 0% to 53%. CONCLUSIONS Detailed and prospective data on acute SLA are lacking. Its real incidence is unclear and it is not possible to analyse surgical outcomes conclusively according to different direction of drainage. The routine use of MRI in complicated anorectal sepsis would specify the surgical anatomy of SLA before any drainage is carried out.

Abstract
BACKGROUND The randomized, double-blind OlympiA trial compared 1 year of the oral poly(adenosine diphosphate-ribose) polymerase inhibitor, olaparib, to matching placebo as adjuvant therapy for patients with pathogenic or likely pathogenic variants in germline BRCA1 or BRCA2 (gBRCA1/2pv) and high-risk, human epidermal growth factor receptor 2-negative, early breast cancer (EBC). The first pre-specified interim analysis (IA) previously demonstrated statistically significant improvement in invasive disease-free survival (IDFS) and distant disease-free survival (DDFS). The olaparib group had fewer deaths than the placebo group, but the difference did not reach statistical significance for overall survival (OS). We now report the pre-specified second IA of OS with updates of IDFS, DDFS, and safety. PATIENTS AND METHODS One thousand eight hundred and thirty-six patients were randomly assigned to olaparib or placebo following (neo)adjuvant chemotherapy, surgery, and radiation therapy if indicated. Endocrine therapy was given concurrently with study medication for hormone receptor-positive cancers. Statistical significance for OS at this IA required P < 0.015. RESULTS With a median follow-up of 3.5 years, the second IA of OS demonstrated significant improvement in the olaparib group relative to the placebo group [hazard ratio 0.68; 98.5% confidence interval (CI) 0.47-0.97; P = 0.009]. Four-year OS was 89.8% in the olaparib group and 86.4% in the placebo group (Δ 3.4%, 95% CI -0.1% to 6.8%). Four-year IDFS for the olaparib group versus placebo group was 82.7% versus 75.4% (Δ 7.3%, 95% CI 3.0% to 11.5%) and 4-year DDFS was 86.5% versus 79.1% (Δ 7.4%, 95% CI 3.6% to 11.3%), respectively. Subset analyses for OS, IDFS, and DDFS demonstrated benefit across major subgroups. No new safety signals were identified including no new cases of acute myeloid leukemia or myelodysplastic syndrome. CONCLUSION With 3.5 years of median follow-up, OlympiA demonstrates statistically significant improvement in OS with adjuvant olaparib compared with placebo for gBRCA1/2pv-associated EBC and maintained improvements in the previously reported, statistically significant endpoints of IDFS and DDFS with no new safety signals.

Abstract
Background and Objectives Data on the clinical efficacy of EUS-guided ablation using the HybridTherm-Probe (EUS-HTP) in locally advanced pancreatic ductal adenocarcinoma (LA-PDAC) are lacking. The aim of the study was to assess the impact of EUS-HTP added to chemotherapy (CT) on overall survival (OS) and progression-free survival (PFS) of LA-PDAC patients with local disease progression (DP) after first-line therapy, compared to CT alone in controls. Methods LA-PDAC cases, prospectively treated by EUS-HTP, were retrospectively compared to matched controls (1:2) receiving standard treatment. Study endpoints were the OS and PFS from local DP after first-line therapy, compared through log-rank test calculating hazard ratios and differences in restricted mean OS/PFS time (RMOST/RMPFST) within prespecified time points (4, 6, and 12 months). Results Thirteen cases and 26 controls were included. Clinical, tumor, and therapy features before and after first-line therapy were case-control balanced. The median OS and PFS were not significantly improved in cases over controls (months: 7 vs. 5 and 5 vs. 3, respectively). At 4 and 6 months, the RMPFST difference was in favor of cases (P = 0.0001 and P = 0.003, respectively). In cases and controls not candidate to further CT (N = 5 and N = 9), the median OS and PFS were not significantly improved in cases over controls (months: 6 vs. 3 and 4 vs. 2, respectively), but the RMPFST difference was in favor of cases at 4 months (P = 0.002). Conclusions In locally progressive PDAC patients experiencing failure of first-line therapy, EUS-HTP achieves a significantly better RMPFST up to 6 months compared to standard treatment, although without a significant impact on OS.

Abstract
BACKGROUND Endoscopic ultrasound (EUS)-guided radiofrequency ablation (RFA) has recently been proposed as a local treatment for functional pancreatic neuroendocrine neoplasms in patients unfit for surgery, in order to obtain clinical syndrome regression. Data on the safety and long-term effectiveness of this approach are scarce, and EUS-RFA procedures are not standardized.
CASE SUMMARY The present case series reports 3 elderly patients with a pancreatic insulinoma and comorbidities, locally treated by EUS-guided RFA with clinical success in terms of hypoglycemic symptoms. RFA procedures were performed during deep sedation, under EUS control with a 19 G needle, an electrode 5-mm in size at a power of 30 W and multiple RFA applications during the same session in order to treat the whole area of the lesions. Immediate relief of symptoms was evident in 2 patients after the first EUS-RFA, while in the third patient a second endoscopic treatment was needed. All 3 patients are symptom-free without need of medications after 24 mo of follow-up with imaging follow-up showing no disease recurrence. A single adverse event of intraprocedural bleeding occurred, which was successfully treated endoscopically.
CONCLUSION EUS-RFA represents an effective and safe alternative to surgery for the treatment of insulinomas in elderly patients at high surgical risk. However, larger multicenter studies with longer follow-up are needed in order to better assess its safety and clinical success.

Abstract
Abstract
Study question
How (neo)adjuvant chemotherapy and concurrent administration of luteinizing hormone-releasing hormone agonist (LHRHa) affect Anti-Mullerian hormone (AMH) and estradiol level dynamics in premenopausal breast cancer patients.
Summary answer
Breast cancer chemotherapy has a major negative impact on patients’ ovarian function and reserve. Women receiving LHRHa showed higher probability of long-term ovarian function recovery.
What is known already
The risk of developing treatment-induced premature ovarian insufficiency (POI) and infertility following chemotherapy is among the most important concern in premenopausal breast cancer patients.
AMH is a promising biomarker for assessing treatment-induced gonadotoxicity in patients receiving anticancer therapies.
Concurrent administration of LHRHa with chemotherapy is associated with a lower risk of treatment-induced ovarian failure and higher rates of menstrual function recovery. However, data on the impact of LHRHa during chemotherapy on patients’ ovarian reserve are still insufficient.
Study design, size, duration
Between 2003 and 2008, the PROMISE-GIM6 trial randomized 281 premenopausal early breast cancer women to receive chemotherapy alone (control group) or chemotherapy plus triptorelin (LHRHa group). Primary endpoints were incidence of early menopause and long-term ovarian function. For exploratory purposes in a subset of patients, AMH and estradiol levels were measured at baseline, <3 months after last cycle of chemotherapy, 1 year after last cycle of chemotherapy, and at the end of adjuvant endocrine treatment.
Participants/materials, setting, methods
The main results of the trial showed that use of concurrent LHRHa significantly reduced the risk of early menopause, increased the chances of long-term ovarian function recovery and did not influence survival outcomes (JAMA 2011, JAMA 2015, JNCI 2022). The present exploratory analysis reports on dynamics of ovarian biomarkers (AMH and estradiol) at baseline and following (neo)adjuvant chemotherapy.
Main results and the role of chance
Out of 281 enrolled patients, 48 enrolled at the coordinating centers had at least one measurement of AMH and estradiol levels at baseline and after (neo)adjuvant chemotherapy. Baseline patient characteristics were similar between treatment arms, with median age being 41 and 39 years, and median AMH levels being 3.9 and 4.9 mcg/L in the control and LHRHa groups, respectively.
In the overall population, estradiol levels showed a significant decrease at the end of chemotherapy, a significant increase after one year, and a return to baseline values at the end of endocrine therapy. By contrast, AMH levels showed a constant decrease over time.
As compared to patients in the control group, those in the LHRHa group had a significant reduction in the risk of early menopause (p = 0.02) and significantly higher estradiol levels at the end of chemotherapy and 1 year after chemotherapy (p < 0.001), suggesting a higher probability of ovarian function recovery. By contrast, no significant differences were observed in the AMH level dynamics between patients receiving LHRHa and those who did not.
Limitations, reasons for caution
Relatively small number of included patients (n = 48) and small number of patients with AMH and estradiol levels determined at each timepoint.
Wider implications of the findings
This biomarker analysis within a phase III randomized trial confirmed that patients receiving LHRHa had a higher probability of ovarian function recovery also supported by estradiol dynamics. However, both patients in the LHRHa and control group showed a major decline in AMH levels after chemotherapy that persisted over time.

Abstract
Background and aim: Based upon a person-centred approach, there is a growing interest in neurobiological transdiagnostic factors, such as reactive temperament (Behavioral Inhibition (BIS) and Behavioral Activation Systems (BAS)) and regulatory processes (Effortful Control (EC)). Three temperament-based personality types (Resilient, Undercontrolled and Overcontrolled type (RUO)) have been replicated in adolescents and younger adults with several clinical problems; with the resilient type (highest scores on EC) consistently showing less psychological symptoms. However, these RUO types have not been studied yet in older adults with mental disorders. Therefore, the current study investigates (1) whether these RUO types can be replicated based on the aforementioned reactive and regulative temperamental factors in older inpatients and (2) whether a higher EC is related to the presence of less psychopathology. Methods: The EC, BIS/BAS, SCL-90-R and ADP-IV questionnaires were administered to 96 older patients (<= 60 years) admitted to a psychiatric hospital. Results: Cluster analysis resulted in a solution of three atypical types: a Resilient type (low BIS, mean BAS, high EC), a Dysregulated type (high BIS, high BAS, low EC) and an “Apathic” type (mean BIS, low BAS, mean EC). Comparison of means revealed that the Resilient type has the highest scores on EC and shows less clinical symptoms and maladaptive personality traits. Discussion: Of the 3 RUO types, only the Resilient type was fully replicated in older psychiatric patients. Strengthening EC might be useful as an additional therapy in order to reduce clinical symptoms, possibly leading to a better treatment outcome.

Abstract
Introduction The VISIONARY study examined the intraocular pressure (IOP)-lowering efficacy and tolerability of the preservative-free fixed-dose combination of tafluprost (0.0015%) and timolol (0.5%) (PF tafluprost/timolol FC) in a real-world setting. The country-level data reported herein comprise the largest and first observational study of PF tafluprost/timolol FC therapy in Italy. Methods An observational, multicenter, prospective study included adult Italian patients with open-angle glaucoma (OAG) or ocular hypertension (OHT) demonstrating insufficient response or poor tolerability with topical prostaglandin analogue (PGA) or beta-blocker monotherapy. Treatment was switched to PF tafluprost/timolol FC therapy at baseline. Primary endpoint was the absolute mean IOP change from baseline at Month 6. Exploratory and safety endpoints included change in IOP at Weeks 4 and 12, ocular signs, symptom severity and reporting of adverse events (AEs). Results Overall, 160 OAG/OHT patients were included. Mean ± standard deviation IOP was reduced from 19.6 ± 3.6 mmHg at baseline to 14.5 ± 2.6 mmHg at Month 6 (reduction of 5.1 ± 3.7 mmHg; 24.1%; p < 0.0001). IOP reduction was also statistically significant at Week 4 (23.1%; p < 0.0001) and Week 12 (24.7%; p < 0.0001). Based on data cutoff values for mean IOP change of ≥20%, ≥25%, ≥30% and ≥35%, respective Month 6 responder rates were 68.1%, 48.7%, 36.2% and 26.9%. Most ocular signs and symptoms were significantly reduced in severity from baseline at Month 6. Two non-serious and mild AEs were reported during the study period, among which, one AE was treatment-related (eyelash growth). Conclusion Italian OAG and OHT patients demonstrated a significant IOP reduction from baseline at Week 4 that was maintained over a 6-month period following a switch from topical PGA or beta-blocker monotherapy to PF tafluprost/timolol FC therapy. Severity of most ocular signs and symptoms was significantly reduced during the study period, and PF tafluprost/timolol FC was generally well tolerated.

Abstract
This work studies the stability of wild-type frataxin and some of its variants found in cancer tissues upon Co2+ binding. Although the physiologically involved metal ion in the frataxin enzymatic activity is Fe2+, as it is customarily done, Co2+ is most often used in experiments because Fe2+ is extremely unstable owing to the fast oxidation reaction Fe2+ → Fe3+. Protein stability is monitored following the conformational changes induced by Co2+ binding as measured by circular dichroism, fluorescence spectroscopy, and melting temperature measurements. The stability ranking among the wild-type frataxin and its variants obtained in this way is confirmed by a detailed comparative analysis of the XAS spectra of the metal-protein complex at the Co K-edge. In particular, a fit to the EXAFS region of the spectrum allows positively identifying the frataxin acidic ridge as the most likely location of the metal-binding sites. Furthermore, we can explain the surprising feature emerging from a detailed analysis of the XANES region of the spectrum, showing that the longer 81-210 frataxin fragment has a smaller propensity for Co2+ binding than the shorter 90-210 one. This fact is explained by the peculiar role of the N-terminal disordered tail in modulating the protein ability to interact with the metal.

Abstract
Biliary tract cancers (BTCs) are frequently diagnosed in advanced stages and are highly lethal. Immunotherapy may play a role in the treatment of these patients. Promising results come from monotherapy or combination therapy studies in pretreated patients. In addition, several studies have demonstrated the safety and efficacy of immune checkpoint inhibitors (ICIs) in combination with chemotherapy in treatment-naive patients. Numerous biomarkers have been investigated to define their predictive role in response to ICIs. However, the full extent of the benefit of immunotherapies has not yet been fully established and, except for high microsatellite instability status, no other biomarkers were uniquely predictive of response to ICIs.

Abstract
BACKGROUND For patients with peripheral T-cell lymphoma (PTCL), outcomes using frontline treatment with cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP-like therapy are typically poor. The ECHELON-2 study demonstrated that brentuximab vedotin plus cyclophosphamide, doxorubicin, and prednisone (A+CHP) exhibited statistically superior progression-free survival (PFS) per independent central review and improvements in overall survival versus CHOP for the frontline treatment of patients with systemic anaplastic large cell lymphoma or other CD30-positive PTCL. PATIENTS AND METHODS ECHELON-2 is a double-blind, double-dummy, randomized, placebo-controlled, active-comparator phase III study. We present an exploratory update of the ECHELON-2 study, including an analysis of 5-year PFS per investigator in the intent-to-treat analysis group. RESULTS A total of 452 patients were randomized (1 : 1) to six or eight cycles of A+CHP (N = 226) or CHOP (N = 226). At median follow-up of 47.6 months, 5-year PFS rates were 51.4% [95% confidence interval (CI): 42.8% to 59.4%] with A+CHP versus 43.0% (95% CI: 35.8% to 50.0%) with CHOP (hazard ratio = 0.70; 95% CI: 0.53-0.91), and 5-year overall survival (OS) rates were 70.1% (95% CI: 63.3% to 75.9%) with A+CHP versus 61.0% (95% CI: 54.0% to 67.3%) with CHOP (hazard ratio = 0.72; 95% CI: 0.53-0.99). Both PFS and OS were generally consistent across key subgroups. Peripheral neuropathy was resolved or improved in 72% (84/117) of patients in the A+CHP arm and 78% (97/124) in the CHOP arm. Among patients who relapsed and subsequently received brentuximab vedotin, the objective response rate was 59% with brentuximab vedotin retreatment after A+CHP and 50% with subsequent brentuximab vedotin after CHOP. CONCLUSIONS In this 5-year update of ECHELON-2, frontline treatment of patients with PTCL with A+CHP continues to provide clinically meaningful improvement in PFS and OS versus CHOP, with a manageable safety profile, including continued resolution or improvement of peripheral neuropathy.

Abstract
The aims of this study were to assess the presence of dysgeusia in patients receiving anticancer therapy and to explore possible factors influencing its occurrence. A total of 242 adult patients with histological diagnoses of malignant neoplasia and undergoing all types of anticancer treatment were included in the analysis. Data were collected from May 2019 to November 2019 at the Unit of Medical Oncology of Careggi University Hospital, Florence, Italy. Dysgeusia was assessed using the Chemotherapy-induced Taste Alteration Scale (CiTAS), while treatment-related symptoms were assessed using the Common Terminology Criteria for Adverse Events (CTCAE). Patients were aged 68 ± 13 years, mostly males (65%). A large proportion of them was undergoing chemotherapy (42.2%), while the others were receiving immunotherapy (20.7%), hormone therapy (15.5%), targeted therapy (12.8%), or a combination of them. Overall, 21.5% of patients reported dysgeusia, 17.4% nausea, 10.7% dysosmia, 9.9% xerostomia, 4.5% mucositis, and only 3.7% vomiting. The targeted therapy showed the greatest adverse effects, followed by chemotherapy, immunotherapy, and hormone therapy. When patients with dysgeusia were analyzed, phantogeusia and parageusia was the most affected dimension of gustatory disorders. Significant differences (p < 0.05) in CiTAS scores were found according to treatment-related symptoms for nausea and mucositis.

Abstract
Gastric cancer is one of the most common malignancy worldwide with a prognosis less than 1 year in unresectable or metastatic disease. HER2 expression is the main biomarker to lead the addition of trastuzumab to first line systemic chemotherapy improving the overall survival in advanced HER2-positivegastric adenocarcinoma. The inevitable development of resistance to trastuzumab remains a great problem inasmuch several treatment strategies that have proven effective in breast cancer failed to show clinical benefit in advanced gastric cancer. In this review, we summarize the available data on the mechanisms underlying primary and secondary resistance toHER2-targeted therapy and current challenges in the treatment of HER2-positive advanced gastric cancer refractory to trastuzumab. Further, we describe the prognostic value of new non-invasive screening techniques, the current development of novel agents such us HER2 antibody-drug conjugates and bispecific antibodies, and the strategies with antitumor activity on going.

Abstract
Fluorescence spectroscopy coupled with chemometric tools is a powerful analytical method, largely used for rapid food quality and safety evaluations. However, its potential has not yet been explored in the novel food sector. In the present study, excitation emission matrices (EEMs) of 15 insect powders produced by milling insects belonging to 5 Orthoptera species (Acheta domesticus, Gryllus assimilis, Gryllus bimaculatus, Locusta migratoria, Schistocerca gregaria) from 3 different origins were investigated. Parallel factor (PARAFAC) analysis performed on the overall averaged dataset was validated for five components, highlighting the presence of five different fluorescence peaks. The presence of these peaks was confirmed on each species, suggesting that fluorescence compounds of edible insects are the same in several species. PARAFAC analysis performed on the overall averaged dataset after alternatively adding the EEM recorded from one standard compound allowed to speculate that edible insects fluorescence raises from mixtures of: tryptophan + tyrosine (PARAFAC component-1), tryptophan + tyrosine + tocopherol (PARAFAC component-2), collagen + pyridoxine + pterins (PARAFAC component-3). This study suggests that fluorescence spectroscopy may represent a powerful method for investigating composition and quality of insect-based foods. Fluorescence landscape of edible insects comprises of 5 different peaks. Similar fluorescence compounds are present among several Orthoptera species. Fluorescence peaks of edible insects result from several chemical molecules. Fluorescence intensity of edible insects depends on their species and origin.
