Impact of gender inequality on the educational and career development of young epileptologists in Italy: A survey of the Young Epilepsy Section - Italian chapter.

OBJECTIVE: The Young Epilepsy Section-Italian chapter (YES-I) is the Italian section of the International League Against Epilepsy (ILAE)-YES. It was founded in 2019 with the aim of increasing the involvement of young epileptologists within scientific associations and facilitating their educational training. The Education and Career Task Force designed a survey on the impact of gender inequality on the educational and professional growth of young epileptologists. METHODS: The survey was proposed via QR code during the 43rd National Congress of the Italian League Against Epilepsy (Padua, 8-10 June 2022), and subsequently distributed via email until 7th September 2022. RESULTS: Of the respondents, 73.6% were female. Of note, 51% of the entire sample answered that they found "no impact" of gender on educational activities (64.3% male against 46.1% female). Only 10% of women stated they have seen very much gender-related inequality in their education or career. However, the majority of our cohort (66%) thought that gender had a negative impact on progression within a scientific society, as well as in female leadership roles in clinical practice (67.9%). Furthermore female medical staff received little work recognition (56.6%). Lastly, 83% of responders did not have children, and only 37.7% declared their colleagues to be empathic in relation to absences for family emergencies. CONCLUSIONS: Lack of awareness of the gender inequality issue might explain inconsistencies in the findings of our survey. Despite the remarkable progress of women rights over the last century, our survey suggests that disparities in academic and decision-making roles exist also in the epileptology field.

Clinical presentation and pathogenesis of cold-induced autoinflammatory disease in a family with recurrence of an NLRP12 mutation.

OBJECTIVE: NLRP12 mutations have been described in patients affected with peculiar autoinflammatory symptoms. This study was undertaken to characterize NLRP12 mutations in patients with autoinflammatory syndromes, particularly a novel missense mutation, p.D294E, affecting a protein sequence crucial for ATP binding, which was identified in a Caucasian family with familial cold-induced autoinflammatory syndrome in some family members. METHODS: Fifty patients were tested for NLRP12 mutations. A Caucasian family with the p.D294E missense mutation of NLRP12 in some family members was clinically characterized. In vitro analysis of the effects of the mutation on NF-κB activity was performed in HEK 293 cells after cotransfection of the cells with a luciferase NF-κB-responsive element and mutant or wild-type (WT) NLRP12 expression plasmids. NF-κB activity was also evaluated 24 hours after stimulation with tumor necrosis factor α in monocytes from individual family members carrying the mutation. Furthermore, secretion of interleukin-1ß (IL-1ß), production of reactive oxygen species (ROS), and activation of antioxidant systems in patient and healthy donor monocytes, under resting conditions and after stimulation with pathogen-associated molecular patterns (PAMPs), were also assessed. RESULTS: In the family assessed, the p.D294E mutation segregated in association with a particular sensitivity to cold exposure (especially arthralgias and myalgia), but not always with an inflammatory phenotype (e.g., urticarial rash or fever). In vitro, the mutant protein maintained the same inhibitory activity as that shown by WT NLRP12. Consistently, NLRP12-mutated monocytes showed neither increased levels of p65-induced NF-κB activity nor higher secretion of IL-1ß. However, the kinetics of PAMP-induced IL-1ß secretion were significantly accelerated, and high production of ROS and up-regulation of antioxidant systems were demonstrated. CONCLUSION: Even with a variable range of associated manifestations, the extreme sensitivity to cold represents the main clinical hallmark in an individual carrying the p.D294E mutation of the NLRP12 gene. Although regulation of NF-κB activity is not affected in patients, redox alterations and accelerated secretion of IL-1ß are associated with this mild autoinflammatory phenotype.

Skip pattern approach toward the early access of innovative anticancer drugs.

BACKGROUND: With the rapid development of innovative anticancer treatments, the optimization of tools able to accelerate the access of new drugs to the market by the regulatory authority is a major issue. The aim of the project was to propose a reliable methodological pathway for the assessment of clinical value of new therapeutic innovative options, to objectively identify drugs which deserve early access (EA) priority for solid and possibly in other cancer scenarios, such as the hematological ones. MATERIALS AND METHODS: After a comprehensive review of the European Public Assessment Report of 21 drugs, to which innovation had previously been attributed by the Italian Medicines Agency (Agenzia Italiana del Farmaco, AIFA), an expert panel formulated an algorithm for the balanced use of three parameters: Unmet Medical Need (UMN) according to AIFA criteria, Added Benefit (AB) according to the European Society for Medical Oncology's Magnitude of Clinical Benefit Scale (ESMO-MCBS) criteria and Quality of Evidence (QE) assessed by the Grades of Recommendation Assessment, Development and Evaluation (GRADE) method. By sequentially combining the above indicators, a final priority status (i.e. EA or not) was obtained using the skip pattern approach (SPA). RESULTS: By applying the SPA to the non-curative setting in solid cancers, the EA status was obtained by 5 out of 14 investigated drugs (36%); by enhancing the role of some categories of the UMN, additional 4 drugs, for a total of 9 (64%), reached the EA status: 2 and 3 drugs were excluded for not achieving an adequate score according to AB and QE criteria, respectively. For hematology cancer, only the UMN criteria were found to be adequate. CONCLUSIONS: The use of this model may represent a reliable tool for assessment available to the various stakeholders involved in the EA process and may help regulatory agencies in a more comprehensive and objective definition of new treatments' value in these contexts. Its generalizability in other national contexts needs further evaluation.

Congenital central hypoventilation syndrome: genotype-phenotype correlation in parents of affected children carrying a PHOX2B expansion mutation.

Congenital Central Hypoventilation Syndrome (CCHS) is a rare genetic disorder. Although most CCHS associated PHOX2B mutations occur de novo, about 10% of the cases are inherited from apparently asymptomatic parents, thus confirming variable expressivity and incomplete penetrance of PHOX2B mutations. Three asymptomatic parents of children affected with CCHS, and found to carry the same PHOX2B expansion mutations as their siblings, were studied by overnight polysomnography and somatic mosaicism analysis. In one case, significant sleep breathing control anomalies were detected, while the other two resulted in normal. In tissue-specific allele studies, mosaicism with a comparatively low mutant allele proportion was showed in the two unaffected adult carriers. Accurate polysomnography and assessment of the degree of somatic mosaicism should be conducted in asymptomatic carriers of PHOX2B mutations, as they may unmask subclinical but significant anomalies.

Search for pathogenetic variants of the SPRY2 gene in intestinal innervation defects.

SPRY2 is an inducible inhibitor of signalling mediated by tyrosine kinases receptors, whose targeting causes intestinal hyperganglionosis in mice. In this light, we have undertaken a mutational analysis of the SPRY2 gene in patients affected with intestinal neuronal dysplasia (IND), without detecting nucleotide changes in any of the 26 DNA samples analysed, with the exception of two already known polymorphic variants. A role of the SPRY2 gene in IND pathogenesis can be thus excluded.

Synthetic small-molecule RNA ligands: future prospects as therapeutic agents.

RNA is one of the most intriguing and promising biological targets for the discovery of innovative drugs in many pathologies and various biologically relevant RNAs that could serve as drug targets have already been identified. Among the most important ones, one can mention prokaryotic ribosomal RNA which is the target of several marketed antibiotics, viral RNAs or oncogenic microRNAs that are tightly involved in the development and progression of various cancers. Oligonucleotides are efficient and specific RNA targeting agents but suffer from poor pharmacodynamic and pharmacokinetic properties. For this reason, a number of synthetic small-molecule ligands have been identified and studied upon screening of chemical libraries or focused design of RNA binders. In this review, we report the most relevant examples of synthetic compounds bearing sufficient selectivity to envisage clinical studies and future therapeutic applications with a particular attention for the main strategies that can be undertaken toward the improvement of selectivity and biological activity.

Neuropsychological profile in Italian children with neurofibromatosis type 1 (NF1) and their relationships with neuroradiological data: Preliminary results.

BACKGROUND: Neurofibromatosis type 1 is a genetic disorder associated with cognitive deficits, learning disabilities and behavioral problems. These domains appear to have a still controversial debated association with local areas of T2-hyperintensities on MRI images, called unidentified bright objects (UBOs). METHODS: A cohort of 36 children (aged 7-11 years) included consecutively, underwent neuropsychological and behavioral assessment to determine their cognitive and neuropsychological profile, and the frequency of specific learning disabilities. MRI examination was used to determine the impact of UBOs' presence, number, and location on the cognitive, neuropsychological and behavioral profile, and also the presence of optic glioma. RESULTS: The mean full intelligence quotient was 104.6; only one child had mild intellectual disability. Forty one percent of children had a diagnosis of specific learning disabilities and reading was mainly involved. Twenty per cent had attention problems. All children had normal scores in visuo-motor and visuo-perceptual tests. UBOs were present in 94.0% of the MRI examinations. Two children had optic glioma. Children with UBOs in a specific location and children with UBOs elsewhere were statistically compared, no one of the location seemed to have an impact on general cognition measured with full intelligence quotient. The thalamus was associated with problems in calculation and striatum with behavioral problems. An inverse relationship between the number of UBOs and the full intelligence quotient was present, but without a statistical significance. CONCLUSIONS: In this study, the specific location of UBOs did not seem to influence the general cognitive profile and also the relationship between their number and the full intelligence quotient was not significant; these results are still controversial in literature. Finally, the presence of UBOs in the thalamus and striatum may represent a neuroradiological pattern that influences performances in calculation and behavior respectively in children with Neurofibromatosis type 1.

HIV-1 diversity in Romania.

OBJECTIVES: To evaluate the prevalence and the dynamics of HIV-1 subtypes in Romanian adults and children, and to investigate the origins of the nosocomial epidemic. DESIGN: A total of 1000 serum and plasma samples, from adults (n = 579) and children (n = 421) who were diagnosed as being HIV-1-infected during 1990-1997 in 39 of the 41 Romanian districts, were serotyped. Viral DNA was isolated from blood samples of 84 patients and the viruses were genotyped. METHODS: Serotyping was performed with a peptide subtype-specific enzyme immunoassay (SSEIA), based on in vitro competition for antibody binding between the representative V3 peptides of the different clades (A-F). Proviral HIV-1 DNA was genotyped by heteroduplex mobility assay or by sequence analysis of the C2-V3 env region. RESULTS: SSEIA showed that 93% of the samples from horizontally infected children were serotype F, 1% were serotype B, and the remaining 6% were uninterpretable. In vertically infected children, 74% of strains were serotype F, 10% were serotype A, 3% were serotype B, and 3% were serotype E. Serotype F was also the dominant subtype in adults (68%), but serotypes A, B, C, D and E were also detected. SSEIA gave indeterminate results in 7% of cases. A strong correlation (90%) between serotyping and genotyping for subtype F was found. Analysis of the relative incidence of the different serotypes over a 7-year period (1990-1997) showed a stable distribution. CONCLUSIONS: Subtype F largely dominates the epidemiology of HIV-1 infection in both children and adults in Romania, although other major subtypes are present. The predominance of subtype F in Romania may be a future potential source of HIV-1 variability in Europe.

Micro-injection of recombinant lysyl oxidase blocks oncogenic p21-Ha-Ras and progesterone effects on Xenopus laevis oocyte maturation.

Previous evidence suggested an anti-oncogenic role for lysyl oxidase, mainly in ras-transformed cells. Here we prove that recombinant lysyl oxidase is actually able to antagonize p21-Ha-Ras-induced Xenopus laevis oocyte maturation. Lysyl oxidase was also effective on progesterone-dependent maturation, indicating a block lying downstream of Ras. Maturation induced by activated 'maturation promoting factor', normally triggered by progesterone, was also inhibited by lysyl oxidase. Finally, lysyl oxidase did not abolish p42Erk2 phosphorylation upon maturation triggering, suggesting a block downstream of Erk2. Further investigation showed that lysyl oxidase action depends on protein synthesis and is therefore probably mediated by a newly synthesized protein.

A sequential chemo-radiotherapeutic treatment for patients with malignant gliomas: a phase II pilot study.

BACKGROUND: The purpose of our study was to evaluate the activity and toxicity of a sequential chemo-radiotherapeutic treatment on the basis of an earlier report by The Johns Hopkins Oncology Center. MATERIALS AND METHODS: Eighteen patients with histologically diagnosed malignant gliomas entered the study. Fifteen patients had glioblastoma multiforme (83%). BCNU (40 mg/sqm/die) and Cisplatin (40 mg/sqm/die) were administered concurrently for 3 days every 3-4 weeks. Radiotherapy consisted of 45 Gy whole cranial irradiation plus a 15 Gy boost on the preoperative volume. RESULTS: Thirteen patients had measurable disease and were evaluable for response. After chemotherapy we obtained 3 CRs (complete remission) and 4 PRs (partial remission) (RR (response rate 54%). Three PRs were converted to CRs after radiotherapy, for a complete remission rate of 46% (6/13). The median duration of response was 10 months. The median survival of the entire patients population was 9 months with 33% survival rates at 1 year. Hematological toxicity grade 4 in one patient and grade 3 in two patients were the major complications due to chemotherapy. CONCLUSIONS: Our sequential chemo-radiotherapeutic regimen appears to have significant activity in adults with newly diagnosed high-grade gliomas.

[Preoperative and immediate postoperative respiratory therapy in patients with pulmonary resection]. / La fisiokinesiterapia respiratoria nella preparazione all'intervento e nel trattamento postoperatorio immediato dei pazienti sottoposti a resezione polmonare.

Twenty patients with a resectable lung cancer and with a low respiratory function were included in this study. During the preoperative period all patients underwent a physiokinesic preparation in view of some improvement of their ventilation performances. Methodology as well as results are reported good response to the program, better post-operative functional recovery and absence of complications were observed in this group of patients.

[The clinical and immunological correlations between the p24 antigenemia levels and those of anti-p24 antibodies in HIV-seropositive children]. / Corelatii clinice si imunologice între nivelurile antigenemiei p24 si cele ale anticorpilor anti-p24 la copii HIV seropozitivi.

The influence of HIV I p24 antigen immune complexing with anti-p24 antibodies of the assessment of their respective levels in HIV-positive sera was studied. ELISA tests were used for evaluating anti-p24 and p24 antigenemia, with or without acid dissociation. We have observed that: 1. p24 antigenemia usually coexisted with low anti-p24 levels, an inverse correlation between these two parameters being traced; acid dissociation increased the percentage of p24 positive sera, especially when anti-p24 titers are low; 2. on contrary, after acid dissociation, p24 Ag remain undetectable in 55.56% of patients presenting high titers and 29.41% of those with low levels of anti-p24; acid dissociation do not increase anti-p24 titers. Whereas the first group of observations suggests that p24 Ag and anti-p24 Ab may be involved in immune complexes, the second set indicates that p24 Ag and Ab were not inevitably linked in such complexes. So, they may be indicative for two distinct biological phenomena.

[The specific serological profile in hepatitis B virus infection in children]. / Profil serologic particular în infectia cu virusul hepatitei B la copii.

UNLABELLED: Hepatitis B virus infection (HBV) has a very well known specific serologic profile. In the last years the molecular biology methods reveal some "particular serological profiles" by genomic mutation. One particular profile consists in the absence of anti-HBc total antibodies simultaneously with the presence of HBsAg. Our tested group consists of 372 children aged 0.1 to 15 years. The presence of HBsAg was determined by ELISA "sandwich" and confirmed by neutralisation test. For HIV infection we used two ELISA tests (competitive and indirect) and the Western Blot test for confirmation. Of the total, there were 13 children HBsAg positive and without anti-HBc antibody (3.49% respectively), 7 of the 13 children (53.8%) were dystrophic and 4 were HIV positive (30.76%). From 372 cases, 104 were HBsAg positive (27.9%) and 53 (14.2%) of them had chronic hepatitis. CONCLUSIONS: 1. The particular serologic profile requires the testing of all serological markers specific for HBV. 2. This particular serologic profile is correlated with HIV positive status and dystrophy.

[The prevalence of HBsAg in hospitalized children as a marker of hepatitis B virus infection]. / Prevalenta AgHBs la copii spitalizati, ca marker al infectiei cu virusul hepatitei B.

UNLABELLED: The aim of this study was to determine the prevalence of hepatitis B surface antigen (HBsAg) in hospitalised children, as specific marker for hepatitis B virus (HBV) infection. Our study group consists of 517 children, 68 of them diagnosed with chronic hepatitis. For HBsAg determination we used an ELISA test (Labsystems); for some children we also tested by ELISA the following markers: the antibodies and anti-hepatitis C virus (HCV) antibodies. From 517 children 24.28% were HBSAg positive and 75% of children with chronic hepatitis were positive for the same marker. Almost 100% of chronic active hepatitis (CAH) patients was positive for HBSAg. CONCLUSIONS: 1. The prevalence of HBsAg was much higher as compared with the healthy population prevalence; it is a clear prove that HBV infection has an important role in chronic hepatitis appearance. 2. For all HBsAg positive patients, it is necessary to determine other markers like HBeAg-anti-HBe antibodies system as well as markers for other viral hepatitis (HDV, HCV). 3. The anti-HBV infection vaccine will reduce significantly the prevalence of HBV and HDV infections; 4. Biological molecular technique, like PCR will be necessary in our country, in the future, even the price is so high, to monitoring the IFN treatment for chronic infection as unique solution for these patients.
