RESUMEN
URBAN is a multicentric, ambispective study evaluating the effectiveness and safety of obinutuzumab-based immuno-chemotherapy and maintenance in patients with untreated advanced follicular lymphoma (FL). The study began before the COVID-19 emergency declaration in Italy. It is currently ongoing for follow-up, and the enrolment timeline encompassed different stages of the pandemic, various vaccination roll-out phases and prevalence of SARS-CoV-2 variants. Outcomes of interest of the present sub-analysis included SARS-CoV-2 infection rates and COVID-19-related hospitalizations/deaths. At data cut-off, 86 (28.8%) and 213 patients (71.2%) were treated before and during/after the COVID-19 outbreak respectively; 294 (98.3%) completed the induction, 31 (10.4%) completed maintenance and 170 (56.9%) were still on maintenance. Overall, 245 patients (81.9%) received at least one SARS-CoV-2 vaccine dose: 13.5%, 31.4% and 55.1% received one, two and three doses respectively. We observed a substantial decrease in COVID-19-related mortality rates in pre- versus post-vaccination phases, along with a reduction in COVID-19-related outcomes due to the shift from alpha/delta to omicron variant predominance. No differences emerged between patients given maintenance or not, although the schedule was modified in 65% of cases. To our knowledge, URBAN represents the largest dataset of COVID-19-related outcomes in FL patients extensively exposed to obinutuzumab. ClinicalTrials.gov identifier: NCT04034056.
RESUMEN
OBJECTIVE: Iloprost (ILO) is recommended for the treatment of systemic sclerosis (SSc) microangiopathy, but there is no common consensus on its optimal dosage. The aim of this study is to evaluate the kinetics of response to ILO administered in a daily outpatient scheme in SSc subjects using laser speckle contrast analysis (LASCA). METHOD: Adult SSc patients in stable therapy with ILO administered for 6 h for 2 consecutive days every 4 weeks were enrolled. Peripheral finger perfusion was assessed by LASCA. Each patient underwent five LASCA evaluations: before and after each day of ILO (D1pre, D1post, D2pre, and D2post) and after 4 weeks (D30). RESULTS: Twenty-seven SSc patients (77.8% female, mean age 61.5 years) were enrolled. LASCA showed an increase in perfusion at the end of each ILO course, but on the second day (both D1pre vs D2pre and D2pre vs D2post) the increase was no longer significant in half of the fingers. Moreover, compared to D1post, at the beginning of the second ILO day most of the fingers had already shown a significant reduction in perfusion. After 1 month, there were no statistically significant differences between the perfusion values of D1pre and D30. CONCLUSION: This LASCA study highlights the transience of the vasoactive effect of ILO, with a perfusion benefit that is completely lost after 1 month. The brevity of the perfusion effect of ILO and the use of LASCA are elements to consider in the design of future SSc trials to determine the optimal ILO dosage.

Objectives: Intravenous iloprost (ILO) has widely demonstrated its effectiveness and safety in systemic sclerosis (SSc) patients. Unfortunately, there is no clear consent about dosage, duration, frequency, and infusion modality. The aim of this study was to compare two different therapeutic schemes in the same cohort of consecutive SSc subjects, evaluating differences in terms of effectiveness [digital ulcer (DU) outcome], safety, and direct healthcare costs.Method: This was a retrospective observational study of 47 patients classified with SSc treated with intravenous ILO for severe Raynaud's phenomenon and/or DUs. Two regimens were compared: a continuous inpatient scheme and a daily outpatient scheme. Demographics and clinical data, concomitant therapies, adverse events, and data on resource use and costs were collected.Results: The number of DUs rose slightly with the switch from the continuous to the daily scheme (0.61 ± 1.2 vs 1.1 ± 1.7). Moreover, in the daily scheme there was an increase in the number of therapeutic cycles (2.4 ± 0.7 vs 4.71 ± 1.4, p < 0.001) and an increase in patients treated with other vasoactive drugs. There was a reduction in ILO tolerability and more than half of the patients suspended the treatment. Five patients required hospitalization for severe and refractory DUs in the daily scheme. Moreover, the costs of the two treatments were comparable [median 7174 (range 2748-18 524) EUR vs 6284 (3232-22 706) EUR, p = 0.712].Conclusion: Treatment with a daily scheme of ILO is characterized by worse tolerability and a higher dropout rate compared to a low-flow regimen, with similar costs. We suggest that a low-flow continuous therapeutic scheme is preferable in SSc patients.

The objective of this article is to present a literature review concerning the psychiatric consequences associated with the Covid 19 pandemic, in the pediatric population. This review is realized with Pubmed Database, using Covid 19, Coronavirus, child, children, adolescent, mental health, psychiatric or psychological consequences as keywords. We propose to present an inventory of current research based on three factors: fear linked to the pandemic, the consequences of the stay-at-home confinement, and the risks of cumulative trauma. We will present three clinical vignettes of children who were followed during the health crisis following the development of symptoms related to the health situation. We will end with some perspectives on the management of the health crisis by child and adolescent psychiatry services.
RESUMEN
PURPOSE: There is growing interest in low-dose metronomic chemotherapy (LDMC) in metastatic breast cancer (MBC). In this retrospective case-control analysis, we compared the efficacy of LDMC and conventional chemotherapy (CCT) in MBC. METHODS: Each LDMC patient receiving oral cyclophosphamide (CTX) (50 mg daily) and methotrexate (MTX) (2.5 mg every other day) was matched with two controls who received CCT. Age, number of chemotherapy lines and metastatic sites as well as hormone receptor (HR) status were considered as matching criteria. Primary endpoint was disease control rate longer than 24 weeks (DCR). Secondary endpoints were progression-free survival (PFS), duration of response (DoR) and subgroup analyses using the matching criteria. RESULTS: 40 cases and 80 controls entered the study. 30.0% patients with LDMC and 22.5% patients with CCT showed DCR (p = 0.380). The median PFS was 12.0 weeks in both groups (p = 0.218) and the median DoR was 31.0 vs. 20.5 weeks (p = 0.383), respectively. Among younger patients, DCR was 40.0% in LDMC vs. 25.0% in the CCT group (p = 0.249). DCR was achieved in 33.3% vs. 26.2% non-heavily pretreated patients (p = 0.568) and in 36.0% vs. 18.0% patients without multiple metastases (p = 0.096), respectively. In the HR-positive group, 30.0% LDMC vs. 28.3% CCT patients showed DCR (p = 1.000). Among triple-negative patients, DCR was achieved in 30.0% LDMC and 5.0% CCT patients (p = 0.095). CONCLUSIONS: We demonstrated a similar efficacy of LDMC compared to CCT in the treatment of MBC. Thus, LDMC may be a valuable treatment option in selected MBC patients.

PURPOSE: Evaluating consecutive early breast cancer patients, we analyzed both the impact of EndoPredict® on clinical decisions as well as clinico-pathological factors influencing the decision to perform this gene expression test. METHODS: Hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative early breast cancer patients treated between 2011 and 2016 were included in this study to investigate the role of EndoPredict® (EPclin) in the treatment of early breast cancer. A main study aim was to analyze the changes in therapy recommendations with and without EPclin. In addition, the impact of clinico-pathological parameters for the decision to perform EPclin was examined by Pearson's chi-squared test (χ2-test) and Fisher's exact test as well as univariate and multivariate logistic regressions. RESULTS: In a cohort of 869 consecutive early HR-positive, HER-negative breast cancer patients, EPclin was utilized in 156 (18.0%) patients. EPclin led to changes in therapy recommendations in 33.3% (n = 52), with both therapy escalation in 19.2% (n = 30) and de-escalation in 14.1% (n = 22). The clinico-pathological factors influencing the use of EPclin were age (P < 0.001, odds ratio [OR] 0.498), tumor size (P = 0.011, OR 0.071), nodal status (P = 0.021, OR 1.674), histological grade (P = 0.043, OR 0.432), and Ki-67 (P < 0.001, OR 3.599). CONCLUSIONS: EPclin led to a change in therapy recommendations in one third of the patients. Clinico-pathological parameters such as younger age, smaller tumor size, positive nodal status, intermediate histological grade and intermediate Ki-67 had a significant influence on the use of EndoPredict®.

Whole exome sequencing detected novel likely pathogenic variants in LRP2 gene in 2 patients presenting with hearing and vision loss, and the Dent disease (DD) classical renal phenotype, that is, low molecular weight proteinuria (LMWP), hypercalciuria and nephrocalcinosis/nephrolithiasis. We propose that a subset of patients presenting as DD may represent unrecognized cases or mild forms of Donnai-Barrow/facio-oculo-acustico-renal (DB/FOAR) syndrome or be on the phenotypic continuum between the 2 conditions.

Choices have to be made to manage invasive species because eradication often is not possible. Both ecological and social factors have to be considered to improve the efficiency of management plans. We conducted a social study on Fallopia spp., a major invasive plant taxon in Europe, including (1) a survey on the perception of a landscape containing Fallopia spp. using a photoquestionnaire and (2) an analysis of the social representations of Fallopia spp. of managers and users in one highly invaded area and one less invaded area. The respondents to the photoquestionnaire survey appreciated the esthetics of the landscapes less when tall Fallopia spp. were present. Few people were able to identify and name the plant, and this knowledge negatively affected the appreciation of the photos containing Fallopia spp. The central core of the social representation of Fallopia spp. was composed of the invasive status of the plant, its density, and its ecological impacts. The peripheral elements of the representation depended on the people surveyed. The users highlighted the natural aspect whereas the managers identified the need for control. In the invaded area, the managers qualified the species as "unmanageable," whereas the species was qualified as "foreign" in the less invaded area. Those results provide insights that have to be included when objectives of management plans of these species are selected.

BACKGROUND: The role of different subtypes of immune cells is still a matter of debate. METHODS: We compared the prognostic relevance for metastasis-free survival (MFS) of a B-cell signature (BS), a T-cell signature (TS), and an immune checkpoint signature (CPS) in node-negative breast cancer (BC) using mRNA expression. Microarray-based gene-expression data were analyzed in six previously published cohorts of node-negative breast cancer patients not treated with adjuvant therapy (n = 824). The prognostic relevance of the individual immune markers was assessed using univariate analysis. The amount of independent prognostic information provided by each immune signature was then compared using a likelihood ratio statistic in the whole cohort as well as in different molecular subtypes. RESULTS: Univariate Cox regression in the whole cohort revealed prognostic significance of CD4 (HR 0.66, CI 0.50-0.87, p = 0.004), CXCL13 (HR 0.86, CI 0.81-0.92, p < 0.001), CD20 (HR 0.76, CI 0.64-0.89, p = 0.001), IgκC (HR 0.81, CI 0.75-0.88, p < 0.001), and CTLA-4 (HR 0.67, CI 0.46-0.97, p = 0.032). Multivariate analyses of the immune signatures showed that both TS (p < 0.001) and BS (p < 0.001) showed a significant prognostic information in the whole cohort. After accounting for clinical-pathological variables, TS (p < 0.001), BS (p < 0.05), and CPS (p < 0.05) had an independent effect for MFS. In subgroup analyses, the prognostic effect of immune cells was most pronounced in HER2+ BC: BS as well as TS showed a strong association with MFS when included first in the model (p < 0.001). CONCLUSION: Immune signatures provide subtype-specific additional prognostic information over clinical-pathological variables in node-negative breast cancer.

Although non-motor symptoms (NMS) of Parkinson's disease (PD) are very common also in early stages of the disease, they are still under-recognized. Screening tools for non-motor symptoms, such as non-motor symptoms questionnaire (NMSQuest), help clinicians to recognize NMS and to evaluate if patients could require further assessment or specific treatments. To validate an adapted Italian version of NMSQuest and study its psychometric properties, Italian PD patients self-completed Italian NMSQuest, and then underwent a standard clinical evaluation including motor assessment (by Hoehn and Yahr staging, unified Parkinson's disease rating scale part III) and non-motor assessment (by Montreal cognitive assessment, Beck depression inventory, neuropsychiatric inventory, Epworth sleepiness scale, scale for outcomes in Parkinson's disease-Autonomic and movement disorder society-sponsored revision of the unified Parkinson's disease rating scale part I). Somatic comorbidities were quantified using the modified cumulative illness rating scale (CIRS). Seventy-one subjects were assessed (mean age years 69.8 ± 9.6 SD; 31% women; mean duration of disease 6.3 ± 4.6 years; H&Y median 2). Italian NMSQuest showed adequate satisfactory clinimetrics in terms of data quality, precision, acceptability, internal consistency and reliability. A significant correlation was found between NMSQuest and most of non-motor assessment scales, while no significant correlation appeared with motor severity as well as with age of patients, disease duration, levodopa equivalent daily dose, L-DOPA/dopamine agonists assumption and CIRS total score. The Italian version of the NMSQuest resulted as a reliable instrument for screening NMS in Italian PD patients.

There is a controversy regarding ovarian metastasis in early-stage adenocareinoma of the uterine cervix. The authors present the case of a 5 1-year-old woman that at the time of diagnosis was thought to suffer from a Stage II cervical carcinoma and a synchronous ovarian carcinoma, that turned out to be an ovarian metastasis from the endocervical adenocarcinoma, as attested morphologically, histochemically, and immunohistochemically. Radical hysterectomy with oophorectomy, excision of the omentum, lymph node excision, and cytological sampling of the peritoneal cavity were carried out. It is important to always bear in mind that even low-grade adenocarcinomas of the cervix can be metastatic to the ovaries. Clinicians have to be careful when managing those cases, while further investigation is needed in order to determine the exact mechanism of those metastases and the criteria needed in order to preserve the ovaries in young patients.

PURPOSE: The aim of the present study is to evaluate the auditory system in children affected by myelomeningocele and comparing the results with clinical neurological conditions. MATERIALS AND METHODS: Forty-three children, aged between 7 and 26 years, affected by myelomeningocele were investigated by means of subjective tonal audiometry and objective impedance audiometry (tympanometry and acoustic stapedial reflex). RESULTS: Audiological evaluation showed an alteration in 32 patients (74%%). Nine patients presented a mild hearing loss: bilateral in six cases (three sensorineural, one mixed, and two conductive) and unilateral in three cases (two mixed and one conductive). One patient had moderate unilateral conductive deafness and, finally another one severe unilateral sensorineural. Almost all patients with deafness were affected by myelomeningocele and Chiari II. Stapedial-cochlear reflex investigation showed an alteration in 30 patients (70%): 9 of these also showed deafness while the remaining 21 was normal hearing. In these 30 patients, we demonstrated the presence of myelomeningocele, hydrocephalus, and Chiari II malformation in 21 subjects (70%). CONCLUSION: Otoneurological evaluation is important in myelomeningocele not only at the birth but also in the follow-up. It could have an important prognostic role for neurological impairment.

Adenine phosphoribosyltransferase (APRT) deficiency is a rare autosomal recessive enzyme defect of purine metabolism that usually manifests as 2,8-dihydroxyadenine (2,8-DHA) nephrolithiasis and more rarely chronic kidney disease. The disease is most often misdiagnosed and can recur in the renal allograft. We analyzed nine patients with recurrent 2,8-DHA crystalline nephropathy, in all of whom the diagnosis had been missed prior to renal transplantation. The diagnosis was established at a median of 5 (range 1.5-312) weeks following the transplant procedure. Patients had delayed graft function (n=2), acute-on-chronic (n=5) or acute (n=1) allograft dysfunction, whereas one patient had normal graft function at the time of diagnosis. Analysis of allograft biopsies showed birefringent 2,8-DHA crystals in renal tubular lumens, within tubular epithelial cells and interstitium. Fourier transformed infrared microscopy confirmed the diagnosis in all cases, which was further supported by 2,8-DHA crystalluria, undetectable erythrocyte APRT enzyme activity, and genetic testing. With allopurinol therapy, the allograft function improved (n=7), remained stable (n=1) or worsened (n=1). At last follow-up, two patients had experienced allograft loss and five had persistent chronic allograft dysfunction. 2,8-DHA nephropathy is a rare but underdiagnosed and preventable disorder that can recur in the renal allograft and may lead to allograft loss.

OBJECTIVE: To investigate the role of inflammation in non-allergic rhinitis (NAR) patients in a large series to establish the prevalence of different NAR-subtypes, clinical features and the role of nasal cytology in the diagnostic algorithm. METHODOLOGY: Patients were selected out of 3650 individuals who spontaneously presented at our institution. We consecutively enrolled 519 NAR-patients in an analytical cross-sectional study between November 2007 and June 2013 (level of evidence: 3b). All patients underwent rhinological evaluation including symptoms questionnaire, endoscopy, CT scan, allergy tests and nasal cytology. RESULTS: The inflammatory cell infiltrate affects the severity of symptoms differently, allowing for identification of different phenotypes of NAR. We distinguished two groups: "NAR without inflammation"(NAR-) and "NAR with inflammation"(NAR+), in addition to different NAR-subtypes with inflammation. A significant difference was observed in terms of clinical symptoms and association with comorbidities (previously diagnosed asthma and aspirin intolerance) between NAR, NAR+ and between different NAR+ subtypes. CONCLUSION: Our data suggest that NAR- and NAR with neutrophils behave similarly, showing lower symptom score values and a lower risk of association with comorbidities compared to NAR with eosinophils and mast cells (singularly or mixed). In our belief it is very important to establish the presence and type of inflammation in non-allergic rhinitis patients and nasal cytology is a very useful test in correct differential diagnosis.

AIMS AND METHODS: This study assessed incidence, predictive factors, and outcome of Epstein-Barr virus (EBV) DNAemia in 100 recipients of allogeneic hematopoietic stem cell transplant. A total of 68 patients received anti-thymocyte globulin before unrelated grafts. RESULTS: Cumulative incidence of high-load EBV DNAemia defined by levels >10,000 copies/mL was 14% at 12 months. In multivariate analysis, a CD4+ T-lymphocyte count >50 µL at day +30 was the only factor significantly associated with a reduced risk of high-load EBV DNAemia. Thirteen of 16 patients with high viral loads were preemptively treated with rituximab and achieved EBV DNA negativity. Three patients had already developed post-transplant lymphoproliferative disorder (PTLD) at the time of detection of high EBV DNA loads, and they obtained complete response after rituximab infusions and chemotherapy. Patients with high EBV DNA load had a significantly higher transplant-related mortality (TRM) compared with patients with negative or low viral load (54% vs. 16%, P = 0.009) and a trend to lower overall survival (55% vs. 29%, P = 0.060). CONCLUSION: We conclude that CD4+ cell count at day +30 is a predictive factor for EBV DNAemia and may help identify patients requiring closer monitoring. Although only 3% of patients progressed to PTLD and were all successfully managed, EBV reactivation was associated with higher TRM, mainly because of infections.

OBJECTIVE: P53 tumor suppressor gene plays a role in endometrial carcinogenesis. Former studies described correlations between p53 protein overexpression in endometrial cancer and prognostic factors, measured by immunohistochemistry. But data is still controversial. The aim of this study was to measure p53 and phospho-p53 overexpression by Western blot and evaluate correlations between overexpression and prognostic and clinical factors. Phospho-p53 seems to be the functional p53 protein and was examined for the first time in endometrial cancer. METHODS: 40 patients with endometrial cancer were included in the study. A control group of 20 patients with normal endometrial tissue samples was used. Western blot was performed for detection of p53 and phospho-p53. Clinical and pathological parameters were obtained from medical records. Statistical analysis was performed using the log-rank test, the Mann-Whitney test for two independent groups and the Fisher's exact test for dichotomous groupings. RESULTS: In 17.5% of the patients with endometrial cancer a p53 overexpression could be evaluated. There was a correlation between a p53 overexpression and recurring disease (p: 0.014), a negative progesterone receptor status (p: 0.021) and a low BMI (p: 0.022). Only one of 40 patients had a phospho-p53 expression. CONCLUSION: Western blot is a valid method for the detection of p53 overexpression. As other authors described before, p53 overexpression seems to correlate with negative prognostic factors. The correlation between p53 overexpression and a low BMI may underline the relationship between p53 alterations and biological aggressive endometrial carcinomas.

INTRODUCTION: Patients and operators are exposed during dental practice to an infective risk, which derives especially from microorganisms suspended in aerosols. Environmental microbiological monitoring in dental settings represents a good instrument to detect critical situations. METHODS: In order to investigate environmental microbial contamination level in a local reality, we analyzed water, air and surfaces samples of a community-based dental facility by using protocol and threshold values proposed in a recent multicenter study carried out by the Italian Society of Hygiene, Preventive Medicine and Public Health (S.It.I.) working group "Hygiene in Dentistry". Microbial contamination was assessed in the same room for 4 non-consecutive weeks during all the five working days, before and at the end of the daily activity. Air was sampled also during clinical activity, through both active and passive sampling systems. RESULTS: Contamination of water showed a decrease during activities, while a decrease in air contamination was registered only at the end of the day. Passive sampling values resulted more often above threshold values adopted. At the same time, surfaces contamination increases at the end of the activity. It seems that in the dental clinic analyzed microbial buildup represents the higher critical element. No differences have been registered among the different days of the week. DISCUSSION: Our study highlights the need to improve disinfection procedures and air treatment systems in the considered environment. Microbiological monitoring could represent an important element to detect the presence of risk factors and to adopt control measures.

Making an accurate diagnosis of dementia in Parkinson's disease (PD-D) patients is a challenge that neurologists will have to face in the coming years. In 2007, a Task force of the Movement Disorders Society proposed operational diagnostic criteria for the diagnosis of PD-D, consisting of step I and step II. We assessed the validity of step I with reference to the diagnosis made after a formal neuropsychological evaluation and by applying the current gold standard for the diagnosis of PD-D (DSM IV). Step I had a sensitivity of 78% and a specificity of 95.5%. Step I displayed a positive predictive value of 70%, a negative predictive value of 97%, and an accuracy of 93.4%. The clinimetric properties observed in our setting suggest that step I may be considered as a good screening tool (negative predictive value of 97%); however, using step I alone to make a diagnosis of PD-D may lead to an overestimation of dementia in PD, particularly in patients with considerable dysexecutive deficits (positive predictive value of 70%). In conclusion, formal neuropsychology and longitudinal follow-up are still required for the diagnosis and categorization of dementia in PD.
