Frailty is an age-related syndrome that drives multiple physiological system impairments in some older adults, and its pathophysiological mechanisms remain unclear. We evaluated whether frailty-related biological processes could impair stem cell compartments, specifically the renal stem compartment, given that kidney dysfunctions are frequent in frailty. A well-characterized in vitro nephrosphere model of human adult renal stem/progenitor cells has been instrumental to and was appropriate for verifying this hypothesis in our current research. Evaluating the effects of plasma from older individuals with frailty (frail plasma) on allogeneic renal stem/progenitor cells, we showed significant functional impairment and nuclear DNA damage in the treated cells of the renal stem compartment. The analysis of the frail plasma revealed mitochondrial functional impairment associated with the activation of oxidative stress and a unique inflammatory mediator profile in frail individuals. In addition, the plasma of frail subjects also contained the highest percentage of DNA-damaged autologous circulating hematopoietic progenitor/stem cells. The integration of both molecular and functional data obtained allowed us to discern patterns associated with frailty status, irrespective of the comorbidities present in the frail individuals. The data obtained converged toward biological conditions that in frailty caused renal and hematopoietic impairment of stem cells, highlighting the possibility of concomitant exhaustion of several stem compartments., (© The Author(s) 2024.

Introduction: Spinning Babies® procedures and the Rebozo technique have been recently implemented as additional interventions in laboring women with a fetus in occiput posterior position (OPP) to favor the rotation to an anterior position, which improve birth experience and health outcomes. Our study aimed to compare the probability of occurrence of persistent OPP (POPP) of the fetal head at the second stage of labor between retrospective and prospective cohorts and to assess associated sociodemographic, obstetric and intrapartum factors., Methods: We conducted a combined prospective and retrospective cohort study including 1500 women giving birth in 2017 (retrospective cohort) and 779 between 15 May and 15 December 2023 (prospective cohort). Each cohort was divided into two sub-cohorts depending on presence of OPP. Primary outcomes were compared the probability of occurrence of POPP in the two OPP sub-cohorts by a log binomial regression and logistic regression. A p<0.05 was considered statistically significant. Data analysis was performed using Stata/MP18.0., Results: The proportion of OPP at the onset of labor was similar between the two cohorts (34.9% vs 35.1%). The probability of occurrence of POPP was significantly lower in the prospective OPP sub-cohort (27.7%, n=65/235) compared to the retrospective OPP sub-cohort (35.8%, n=154/430) (risk difference, RD= -0.081; 95% CI: -0.15 - -0.008; p=0.031). In the retrospective OPP sub-cohort, maternal age ≥35 years (RD=0.096; 95% CI: 0.001-0.190, p=0.044) and nulliparity (RD= -0.100; 95% CI: -0.190 - -0.001, p=0.036) were significantly associated with the probability of POPP., Conclusions: Our findings suggest a potential benefit of a set of interventions combining Spinning Babies® and the Rebozo technique in decreasing the probability of POPP., Competing Interests: The authors have completed and submitted the ICMJE Form for disclosure of Potential Conflicts of Interest and none was reported., (© 2024 Fumagalli S. et al.)

COVID-19 has a negative impact on the survival of respiratory patients, especially those with interstitial lung disease. This review aims to better understand the effect of COVID-19 on patients with idiopathic pulmonary fibrosis (IPF). A systematic search of MEDLINE, PubMed, Embase, and Scopus performed from December 2019 up to July 2024 identified relevant studies. Eligibility criteria included English language, sample size ≥10 patients, COVID-19 infection and outcome measures. Two independent reviewers assessed studies using the Newcastle-Ottawa Scale for bias and extracted data. Meta-analysis employed a random-effects model, and the Grading of Recommendations Assessment, Development and Evaluation assessed evidence quality. Outcomes considered were hospitalization, intensive care unit admission, and mortality. Of the 1541 initially identified articles, 6 high-quality studies were included. Meta-analysis revealed a 34% mortality rate [95% confidence interval (CI): 21-48%], 36% hospitalization rate (95% CI: 10-75%), and 31% ICU admission rate (95% CI: 7-71%) among IPF patients with COVID-19. The certainty of evidence was low or very low due to publication bias and heterogeneity. This study underscores the elevated risk of hospitalization and death in IPF patients with COVID-19, emphasizing the vulnerability of this population. Prompt and tailored care is crucial to mitigate the impact of COVID-19 on IPF patients, necessitating proactive measures, vaccination, and comprehensive management.

Background: When a hematological malignancy is diagnosed, the whole family carries the burden of the disease; parents often try to protect minor children from suffering by avoiding communication about their disease. Since 2009, patients with minors at the Adult Hematology Division at San Gerardo Hospital (Monza) can take part in the "Emanuela Project": children can visit parents and talk with psychologists and hematologists, who explain the disease through simple metaphors., Materials and Methods: The EMY STUDY aimed to evaluate the impact of illness-related communication on children's behavior, comparing Monza's experience with other Hematology Units, where the communication is delegated to parents or psychological support. Questionnaires exploring the children's main behaviors (school performance, appetite, sleeping patterns, attachment to family figures, and family dialogue) were administered to both sick (SP) and healthy (HP) parents. From 2017 to 2021, 32 patients were enrolled, 20 from Monza and 12 from other hospitals; 84 questionnaires were globally collected., Results: In Monza's group, no major changes in children's behavior were observed and an open dialogue about the disease was often possible. Disease communication is considered crucial and perceived as a responsibility of parents together with a professional figure, mainly the hematologist. Patients were satisfied with "Emanuela Project," reporting positive effects on doctor-patient relationship. Difficulties in separation were significantly higher at other hospitals (P = .019) than in Monza. While at other centers communication is considered parents' responsibility, Monza's patients emphasize the role of professional figures (P = .007). Differently from other hospitals, the role of the hematologist is crucial to Monza's patients (P = .001)., Conclusion: Disease communication to patients' offspring is a crucial moment in the process of care, and the hematologist can play a major role in this difficult task, with potential positive effects both on children's well-being and on doctor-patient relationship., (© The Author(s) 2024.

Purpose: Antibodies against SARS-CoV-2 spike (anti-S) may confer protection against symptomatic COVID-19. Whether their level predicts progression among those with COVID-19 pneumonia remains unclear., Methods: We conducted a retrospective cohort study to assess predictors of anti-S levels and whether anti-S titer is associated with death or mechanical ventilation (MV). Adults hospitalized for COVID-19 pneumonia between July 2021 and July 2022 were enrolled if anti-S had been measured within 72 h of admission. Predictors of anti-S level were explored using multivariable quantile regression. The association between anti-S levels and 30-day death/MV was investigated via multivariable logistic regression. Analyses were stratified by vaccine status., Results: The median anti-S level was 1370 BAU/ml in 328 vaccinated and 15.5 BAU/ml in 206 unvaccinated individuals. Among the vaccinated, shorter symptom duration (p = 0.001), hematological malignancies (p = 0.002), and immunosuppressive therapy (p = 0.004) were associated with lower anti-S levels. In the unvaccinated group, symptom duration was the only predictor of anti-S levels (p < 0.001). After 30 days, 134 patients experienced death or MV. Among vaccinated individuals, higher anti-S levels correlated significantly with lower death/MV risk (per log 2 increase, OR 0.88, 95%CI 0.81-0.97), irrespective of age and solid malignancies. Among unvaccinated, a marginally protective effect was observed (OR 0.86, 95%CI 0.73-1.01), independent of age, immunosuppressive therapy, and diabetes. Adjustment for monoclonal antibody treatment strengthened the association (OR 0.81, 95%CI 0.68-0.96)., Conclusion: This study suggests that levels of anti-S antibodies can predict critical or fatal outcomes in COVID-19 pneumonia patients, regardless of vaccination. Whether anti-S Ab could guide risk assessment and vaccination boosting merits further evaluation., (© 2024. The Author(s).)

Background: Clinical learning is a crucial component of the midwifery education program, necessary to support the acquisition of professional abilities through the integration of theoretical and practical learning experiences. Evaluating Bachelor of Midwifery students' perception of their clinical learning experiences is important to improve midwifery educational programs., Aim: the objective of this study was the translation, cultural adaptation, and validation of the Midwifery Student Evaluation of Practice (MidSTEP) in a group of Italian midwives' students., Methods: "Translation and Cultural Adaptation of Patient Reported Outcomes Measures - Principles of Good Practice" guidelines were adopted to achieve the MidSTEP Italian version. Exploratory Factor Analysis was performed. Internal consistency for reliability was assessed using Cronbach's alpha reliability coefficient (α) and Omega coefficient (ω), while Intraclass Correlation Coefficients (ICC) were used to determine if the tool was stable over time., Findings: The Italian version of MidSTEP (MidSTEP-IT) has good internal consistency: considering the Clinical Learning Environment Scale, Cronbach's α was 0.839 (for the "Skill Development" subscale α was equal to 0.739 and for the "Philosophy of Midwifery Practice" subscale α was equal to 0.825) while considering the Midwifery Preceptor Scale, Cronbach's α was 0.920. Factor analysis does not fully reflect the factorial analysis of the original version., Conclusion: The MidSTEP-IT had been proven to be a valid and reliable tool, easy and fast to administer, that could be effectively helpful for investigating and measuring the Italian midwifery students' perception of their clinical learning experiences, according to the setting and impact of mentors on their professional growth. It is an innovative tool, valuable in both clinical practice and research to highlight the importance of encouraging a supportive clinical learning environment and an efficient preceptorship., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Diagnostic criteria for juvenile myelomonocytic leukemia (JMML) are currently well defined, however in some patients diagnosis still remains a challenge. Flow cytometry is a well established tool for diagnosis and follow-up of hematological malignancies, nevertheless it is not routinely used for JMML diagnosis. Herewith, we characterized the CD34+ hematopoietic precursor cells collected from 31 children with JMML using a combination of standardized EuroFlow antibody panels to assess the ability to discriminate JMML cells from normal/reactive bone marrow cell as controls (n=29) or from cells of children with other hematological diseases mimicking JMML (n=9). CD34+ precursors in JMML showed markedly reduced B-cell and erythroid-committed precursors compared to controls, whereas monocytic and CD7+ lymphoid precursors were significantly expanded. Moreover, aberrant immunophenotypes were consistently present in CD34+ precursors in JMML, while they were virtually absent in controls. Multivariate logistic regression analysis showed that combined assessment of the number of CD34+CD7+ lymphoid precursors and CD34+ aberrant precursors or erythroid precursors had a great potential in discriminating JMMLs versus controls. Importantly our scoring model allowed highly efficient discrimination of truly JMML versus patients with JMML-like diseases. In conclusion, we show for the first time that CD34+ precursors from JMML patients display a unique immunophenotypic profile which might contribute to a fast and accurate diagnosis of JMML worldwide by applying an easy to standardize single eight-color antibody combination.

Disease progression to accelerated/blast phase (AP/BP) in patients with chronic phase chronic myeloid leukemia (CP-CML) after treatment discontinuation (TD) has never been systematically reported in clinical trials. However, recent reports of several such cases has raised concern. To estimate the risk of AP/BP among TD-eligible patients, we conducted TFR-PRO, a cohort retro-prospective study: 870 CP-CML patients eligible for TD formed a discontinuation cohort (505 patients) and a reference one (365 patients). The primary objective was the time adjusted rate (TAR) of progression in relation to TD. Secondary endpoints included the TAR of molecular relapse, that is, loss of major molecular response (MMR). With a median follow up of 5.5 years and 5188.2 person-years available, no events occurred in the TD cohort. One event of progression was registered 55 months after the end of TD, when the patient was contributing to the reference cohort. The TAR of progression was 0.019/100 person-years (95% CI [0.003-0.138]) in the overall group; 0.0 (95% CI [0-0.163]) in the discontinuation cohort; and 0.030 (95% CI [0.004-0.215]) in the reference cohort. These differences are not statistically significant. Molecular relapses occurred in 172/505 (34.1%) patients after TD, and in 64/365 (17.5%) patients in the reference cohort, p < .0001. Similar rates were observed in TD patients in first, second or third line of treatment. CML progression in patients eligible for TD is rare and not related to TD. Fears about the risk of disease progression among patients attempting TD should be dissipated., (© 2023 The Authors. American Journal of Hematology published by Wiley Periodicals LLC.)

Background: Prone positioning is routinely used among patients with COVID-19 requiring mechanical ventilation. However, its utility among spontaneously breathing patients is still debated., Methods: In an open-label randomised controlled trial, we enrolled patients hospitalised with mild COVID-19 pneumonia, whose arterial oxygen tension to inspiratory oxygen fraction ratio ( P aO 2 / F IO 2 ) was >200 mmHg and who did not require mechanical ventilation or continuous positive airway pressure at hospital admission. Patients were randomised 1:1 to prone positioning on top of standard of care (intervention group) versus standard of care only (controls). The primary composite outcome included death, mechanical ventilation, continuous positive airway pressure and P aO 2 / F IO 2 <200 mmHg; secondary outcomes were oxygen weaning and hospital discharge., Results: A total of 61 subjects were enrolled, 29 adjudicated to prone positioning and 32 to the control group. By day 28, 24 out of 61 patients (39.3%) met the primary outcome: 16 because of a P aO 2 / F IO 2 ratio <200 mmHg, five because of the need for continuous positive airway pressure and three because of the need for mechanical ventilation. Three patients died. Using an intention-to-treat approach, 15 out of 29 patients in the prone positioning group versus nine out of 32 controls met the primary outcome, corresponding to a significantly higher risk of progression among those randomised to prone positioning (HR 2.38, 95% CI 1.04-5.43; p=0.040). Using an as-treated approach, which included in the intervention group only patients who maintained prone positioning for ≥3 h·day -1 , no significant differences were found between the two groups (HR 1.77, 95% CI 0.79-3.94; p=0.165). Also, we did not find any statistically significant difference in terms of time to oxygen weaning or hospital discharge between study arms in any of the analyses conducted., Conclusions: We observed no clinical benefit from prone positioning among spontaneously breathing patients with COVID-19 pneumonia requiring conventional oxygen therapy., Competing Interests: Conflict of interest: The authors declare that they have no conflicts of interest for the present study., (Copyright ©The authors 2023.)

Next-generation Trop-2-targeted therapy against advanced cancers is hampered by expression of Trop-2 in normal tissues. We discovered that Trop-2 undergoes proteolytic activation by ADAM10 in cancer cells, leading to the exposure of a previously inaccessible protein groove flanked by two N-glycosylation sites. We designed a recognition strategy for this region, to drive selective cancer vulnerability in patients. Most undiscriminating anti-Trop-2 mAbs recognize a single immunodominant epitope. Hence, we removed it by deletion mutagenesis. Cancer-specific, glycosylation-prone mAbs were selected by ELISA, bio-layer interferometry, flow cytometry, confocal microscopy for differential binding to cleaved/activated, wild-type and glycosylation site-mutagenized Trop-2. The resulting 2G10 mAb family binds Trop-2-expressing cancer cells, but not Trop-2 on normal cells. We humanized 2G10 by state-of-the-art complementarity determining region grafting/re-modeling, yielding Hu2G10. This antibody binds cancer-specific, cleaved/activated Trop-2 with Kd < 10-12 mol/L, and uncleaved/wtTrop-2 in normal cells with Kd 3.16×10-8 mol/L, thus promising an unprecedented therapeutic index in patients. In vivo, Hu2G10 ablates growth of Trop-2-expressing breast, colon, prostate cancers, but shows no evidence of systemic toxicity, paving the way for a paradigm shift in Trop-2-targeted therapy., (©2023 American Association for Cancer Research.)

Introduction: COVID-19 pandemic had a considerable impact among haematological patients. On the other hand, the effect of this disease on patients (pts) affected by Chronic Myeloid Leukemia (CML) is not clearly defined., Objectives: The primary objective of this study was to evaluate mortality-hospitalization rates and possible protective factors for hospitalization in CML pts affected by COVID., Methods: We collected data from CML patients followed at our institution whotested positive for SARS-CoV-2 infection. The following variables were assessed: demographical data, type of TKI therapy, vaccination status, presence of cardiovascular disease (CVD), period of infection, COVID-19 presenting symptoms, severity and mortality. Data were collected retrospectively and then analysed in univariate and multivariate analysis., Results: Out of a total of 325 CML pts treated at our institution, we recorded 72 SARS-CoV-2pts (22%) who tested positive with a SARS-CoV-2 PCR assay. Twenty two were infected in 2020 (30%), 16 patients in 2021 (22%) and 34 in 2022 (46%); with a hospitalization rate of 27%, 25% and 3% respectively. Of the 72 confirmed infections, 13 pts (18%; (CI) 10-28) were asymptomatic and 48 (66%; CI: 55-76) had mild symptoms. A total of 11 pts were admitted to hospital and 3 of these required ICU admission. No deaths were recorded. The probability of hospitalization was significantly reduced if patients were vaccinated (odds ratio OR 0.037 with CI: 0-0.33 p 0.002) or treated with Bosutinib (OR 0.06 with CI: 0-0.5 p 0.008)., Conclusion: In the present study, no significant increase in mortality was noted among patients with CML as compared to the general population inItaly. Vaccination and treatment with bosutinib were identified as baseline characteristics that were associated with a decreased risk of hospitalitazion resulting from COVID-19 infection., (© 2023 The Authors.

Objective: To evaluate the viability of exoscopes in the context of neurosurgical education and compare the use of a 4k3D exoscope to a traditional operative microscope in the execution of a task of anatomic structure identification on a model of cranial approach., Material and Methods: A cohort of volunteer residents performed a task of anatomical structure identification with both devices three times across an experimental period of 2 months. We timed the residents' performances, and the times achieved were analyzed. The volunteers answered two questionnaires concerning their opinions of the two devices., Results: Across tries, execution speed improved for the whole cohort. When using the exoscopes, residents were quicker to identify a single anatomical structure starting from outside the surgical field when deep structures were included in the pool. In all other settings, the two devices did not differ in a statistically significant manner. The volunteers described the exoscope as superior to the microscope in all the aspects the questionnaires inquired about, besides the depth of field perception, which was felt to be better with the microscope. Volunteers furthermore showed overwhelming support for training on different devices and with models of surgical approaches., Conclusion: The exoscope appeared to be non-inferior to the microscope in the execution of a task of timed identification of anatomical structures on a model of cranial approach carried out by our cohort of residents. In the questionnaires, the residents reported the exoscope to be superior to the microscope in eight of nine investigated domains. Further studies are needed to investigate the use of the exoscope in learning of microsurgical skills., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Calloni, Antolini, Roumy, Nicolosi, Carrabba, Di Cristofori, Fontanella and Giussani.)

Background: Magnetic resonance cholangiopancreatography (MRCP) is the gold standard for diagnosis of patients with primary sclerosing cholangitis (PSC). The semi-quantitative MRCP-derived Anali scores proposed for risk stratification, have poor-to-moderate inter-reader agreement., Aims: To evaluate the prognostic performance of quantitative MRCP metrics in PSC., Methods: This is a retrospective study of PSC patients undergoing MRCP. Images were processed using MRCP+ software (Perspectum Ltd, Oxford) that provides quantitative biliary features, semi-automatically extracted by artificial intelligence-driven analysis of MRCP-3D images. The prognostic value of biliary features has been assessed for all hepato-biliary complications., Results: 87 PSC patients have been included in the analysis. Median follow-up from MRCP to event/censoring of 30.9 months (Q1-Q3=13.6-46.6). An adverse outcome occurred in 27 (31.0%) patients. The number of biliary strictures (HR=1.05 per unit, 95%CI 1.02-1.08, p < 0.0001), spleen length (HR=1.16 per cm, 95%CI 1.01-1.34, p = 0.039), adjusted for height, age at MRCP, and time from diagnosis to MRCP predicted higher risk of hepatobiliary complications. These were incorporated into a the quantitative MRCP-derived PSC (qMRCP-PSC) score (C-statistic=0.80). After 3-fold cross-validation, qMRCP-PSC outperformed the Anali score in our cohort (C-statistic of 0.78 vs 0.64) and enabled the discrimination of survival of PSC patients (log-rank p < 0.0001)., Conclusions: The qMRCP-PSC score identified patients at higher risk of hepatobiliary complications and outperformed the available radiological scores. It represents a novel quantitative biomarker for disease monitoring and a potential surrogate endpoint for clinical trials., Competing Interests: Declaration of Competing Interest RB is CEO at Perspectum Ltd, CF is employed by Perspectum Ltd.

Excess weight and high waist circumference (WC) are associated with increased blood pressure (BP), starting from the pediatric age. Insulin resistance is associated with elevated BP in childhood. The aim of the study was to assess the role of insulin resistance in mediating the relationship between body mass index (BMI), WC, and BP values in a pediatric population referred to a cardio-pediatric center for the presence of one or more cardiovascular risk factors. In 419 children (mean age 10.7 [standard deviation, SD 2.5] years), the following parameters were collected both in basal conditions and after 18.6 (SD 9.3) months of follow-up during which a treatment based on lifestyle and dietary modifications was given: systolic and diastolic BP (SBP and DBP), WC, plasma glucose, and insulin values. The HOMA (Homeostasis Model Assessment)-index was considered as an expression of insulin resistance. At baseline there was a significant correlation between HOMA-index and SBP z-score (β = 0.081, p = 0.003), and insulin resistance was a mediator of the relationship between BMI and SBP z-score ( p = 0.015), and between waist circumference to height (WtHr) and SBP z-score ( p = 0.008). The effect of BMI z-score modifications on SBP z-score changes from baseline to follow-up was totally mediated by HOMA-index changes ( p = 0.008), while HOMA-index only partially mediated the effect of WtHr modifications on SBP z-score changes ( p = 0.060). Our study strongly suggests that, in a pediatric population at cardiovascular risk, the HOMA-index is an important mediator of the relationship between BMI, WC and SBP.

Chronic noncommunicable diseases (NCDs) have become the major cause of morbidity and mortality in the Maldives, triggered by the nutrition transition to a "Western diet" that dramatically increases the prevalence of excess weight and hypertension. Our study aimed to evaluate dietary habits, blood pressure (BP) and body mass index in Maghoodoo Public School's students. A sample of 145 students (72 males and 73 females, age 9.37 ± 2.97 years) was enrolled. Factors causing excess weight were investigated through descriptive statistics. The relationship between blood pressure percentiles and possible influencing factors was investigated by a linear regression model.. Excess weight was present in 15.07% and 12.5% females and males, respectively. 15.18% of the subjects had elevated BP, with a significant difference according to gender detected only in the PAS z -score. Eating habits were investigated through a parent-filled questionnaire; 70.15% of the students consumed less than two portions of fruit per day, with a significant difference between gender (84.06% and 55.38% for boys and girls, respectively, p < 0.0001) and 71.64% ate less than two servings of vegetables per day. An alarming finding emerged for sweet snacks (30.6% of the students consumed 2-3 servings per day) and sugary drinks (2-3 servings per day for 32.84% of students) consumption. Our findings suggest that excess weight and hypertension in this population could be due to energy-rich, packaged-foods consumption. A nutrition education approach might thus help to reduce cardiovascular risk.

It has been argued that metabolically healthy obesity (MHO) does not increase the risk of cardiovascular disease. The aim of this study is to evaluate whether, in a population of obese children/adolescents, the metabolically unhealthy obesity (MUO) phenotype is associated with higher left ventricular mass index and/or higher prevalence of left ventricular hypertrophy than the MHO phenotype. We also tested whether the addition of an insulin resistance index (HOMA-index >90th percentile by sex and age) and the presence of hyperuricemia (serum uric acid >90th percentile by sex and age) to the definition of MUO better identified obese children with early cardiac damage. Left ventricular hypertrophy was defined as the presence of left ventricular mass index greater than or equal to the age- and sex-specific 95th percentile. The study population included 459 obese children (males 53.2%, mean age 10.6 [standard deviation, 2.6] years), of whom 268 (58.4%) were MUO. The left ventricular mass index was higher in MUO children than in MHO children (37.8 vs 36.3 g/m 2.7 , p=0.015), whereas the percentage of MUO children presenting left ventricular hypertrophy was only slightly higher in MUO children (31.1 vs 40%, p=0.06). Multiple linear regression analyses showed that the variables significantly associated with higher left ventricular mass index were male gender (p<0.01), Body Mass Index z-score (p<0.001) and Waist-to-Height-ratio (p<0.001). Multiple logistic regression analyses showed that the presence of left ventricular hypertrophy was only significantly associated with higher Body Mass Index z-score (p<0.05) and Waist-to-Height-ratio (p<0.05). In spite of the higher left ventricular mass index of MUO as compared to MHO children, the MUO phenotype was not a significant predictor of either higher left ventricular mass index or higher left ventricular hypertrophy prevalence. The MUO phenotype had a low predictive ability on the presence of left ventricular hypertrophy. The area under the receiver operating characteristic curve was 0.57 (sensitivity 0.64, 1-specificity 0.55). The addition of insulin resistance and hyperuricemia to the definition of MUO did not change the results observed with the standard definition of MUO at multivariable analysis. The MUO phenotype appears to be of little usefulness in identifying the early presence of cardiac damage in a large population of obese children and adolescents. Excess weight and abdominal obesity are confirmed as an important determinant of early organ damage in obese children., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Genovesi, Tassistro, Giussani, Lieti, Patti, Orlando, Montemerlo, Antolini and Parati.)

Hematological patients at higher risk of severe COVID-19 were excluded from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine trials. In this single-center observational prospective study (NCT05074706), we evaluate immune response in the hematological patients followed at the Hematological Division of San Gerardo Hospital, Monza (Italy) deemed to be severely immunosuppressed after vaccination with two doses of the BNT162b2 vaccine. Anti-SARS-CoV-2 immunoglobulin G titers above the cutoff value of 33.8 BAU/ml were detected in 303 (80.2%) out of the 378 patients enrolled. Patients with lymphoproliferative disorders had a significant lower probability of immunization (43.2% vs. 88.4%, p  < 0.001). Patients treated with anti-CD20 showed a significantly lower probability of immunization compared to all other treatments (21.4%, p  < 0.0001). Among 69 patients who failed seroconversion, 15 patients (22.7%) showed a positive T-cell response. Patients previously treated with anti-CD20 were 2.4 times more likely to test positive for T-cell responses ( p  = 0.014). Within a follow-up of 9 months from the second COVID-19 vaccination, symptomatic SARS-CoV-2 infections were reported by 20 patients (5.3%) and four of them required hospitalization. Successful serological or T-cell-mediated immunization conferred protection from symptomatic COVID-19. Patients treated with anti-CD20 who were not seroconverted after vaccination might still be protected from COVID-19 due to the T-cell immune response., Competing Interests: The authors declare they have no conflicts of interest in relation to the work described., (© 2022 The Authors. eJHaem published by British Society for Haematology and John Wiley & Sons Ltd.)

Rationale: Cardiovascular instability/collapse is a common peri-intubation event in patients who are critically ill. Objectives: To identify potentially modifiable variables associated with peri-intubation cardiovascular instability/collapse (i.e., systolic arterial pressure <65 mm Hg [once] or <90 mm Hg for >30 minutes; new/increased vasopressor requirement; fluid bolus >15 ml/kg, or cardiac arrest). Methods: INTUBE (International Observational Study to Understand the Impact and Best Practices of Airway Management In Critically Ill Patients) was a multicenter prospective cohort study of patients who were critically ill and undergoing tracheal intubation in a convenience sample of 197 sites from 29 countries across five continents from October 1, 2018, to July 31, 2019. Measurements and Main Results: A total of 2,760 patients were included in this analysis. Peri-intubation cardiovascular instability/collapse occurred in 1,199 out of 2,760 patients (43.4%). Variables associated with this event were older age (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.02-1.03), higher heart rate (OR, 1.008; 95% CI, 1.004-1.012), lower systolic blood pressure (OR, 0.98; 95% CI, 0.98-0.99), lower oxygen saturation as measured by pulse oximetry/Fi O 2 before induction (OR, 0.998; 95% CI, 0.997-0.999), and the use of propofol as an induction agent (OR, 1.28; 95% CI, 1.05-1.57). Patients with peri-intubation cardiovascular instability/collapse were at a higher risk of ICU mortality with an adjusted OR of 2.47 (95% CI, 1.72-3.55), P  < 0.001. The inverse probability of treatment weighting method identified the use of propofol as the only factor independently associated with cardiovascular instability/collapse (OR, 1.23; 95% CI, 1.02-1.49). When administered before induction, vasopressors (OR, 1.33; 95% CI, 0.84-2.11) or fluid boluses (OR, 1.17; 95% CI, 0.96-1.44) did not reduce the incidence of cardiovascular instability/collapse. Conclusions: Peri-intubation cardiovascular instability/collapse was associated with an increased risk of both ICU and 28-day mortality. The use of propofol for induction was identified as a modifiable intervention significantly associated with cardiovascular instability/collapse.Clinical trial registered with clinicaltrials.gov (NCT03616054).

Background: The diagnosis of the active phase of labor is a crucial clinical decision, thus requiring an accurate assessment. This study aimed to build and to validate a predictive model, based on maternal signs and symptoms to identify a cervical dilatation ≥4 cm., Methods: A prospective study was conducted from May to September 2018 in a II Level Maternity Unit (development data), and from May to September 2019 in a I Level Maternity Unit (validation data). Women with singleton, term pregnancy, cephalic presentation and presence of contractions were consecutively enrolled during the initial assessment to diagnose the stage of labor. Women < 18 years old, with language barrier or induction of labor were excluded. A nomogram for the calculation of the predictions of cervical dilatation ≥4 cm on the ground of 11 maternal signs and symptoms was obtained from a multivariate logistic model. The predictive performance of the model was investigated by internal and external validation., Results: A total of 288 assessments were analyzed. All maternal signs and symptoms showed a significant impact on increasing the probability of cervical dilatation ≥4 cm. In the final logistic model, "Rhythm" (OR 6.26), "Duration" (OR 8.15) of contractions and "Show" (OR 4.29) confirmed their significance while, unexpectedly, "Frequency" of contractions had no impact. The area under the ROC curve in the model of the uterine activity was 0.865 (development data) and 0.927 (validation data), with an increment to 0.905 and 0.956, respectively, when adding maternal signs. The Brier Score error in the model of the uterine activity was 0.140 (development data) and 0.097 (validation data), with a decrement to 0.121 and 0.092, respectively, when adding maternal signs., Conclusion: Our predictive model showed a good performance. The introduction of a non-invasive tool might assist midwives in the decision-making process, avoiding interventions and thus offering an evidenced-base care., (© 2022. The Author(s).)

Several studies describe the association between serum uric acid (SUA) and arterial stiffness in adults. Uric acid contributes through several mechanisms to the increase in blood pressure (BP) and adversely affects the insulin signaling pathway. Moreover, SUA predict the development of hypertension and insulin resistance up to type 2 diabetes. Early arterial stiffening, estimated by carotid-femoral pulse wave velocity (PWV), may already be present in pediatric age. Aim of our study was to investigate the relationship between SUA and PWV in a pediatric population and its interaction with insulin resistance and BP. In 322 children and adolescents (56.2% male, mean age 11.3 [SD 2.8] years), we measured weight, height, waist circumference, BP and PWV. We also assayed SUA and estimated glomerular filtration rate (eGFR) and calculated HOMA-index as a marker of insulin resistance. Simple and multiple regression analyses were performed to assess variables associated with PWV. Mediation models were applied to identify the direct and indirect effects of individual variables on PWV. On univariate analysis, age ( p < 0.001), waist circumference-to-height ratio ( p = 0.036), systolic and diastolic BP (SBP and DBP) z- score ( p < 0.001), heart rate ( p = 0.028), SUA ( p = 0.002), HOMA-index ( p < 0.001), and eGFR ( p = 0.014) were significantly associated with PWV. The multiple regression model showed that only age ( p = 0.028), SBP z- score ( p = 0.006), and heart rate ( p = 0.001) were significantly associated with PWV. The results were superimposable when the DBP z- score replaced the SBP z- score in the model. Mediation models showed that the effect of eGFR on PWV was fully mediated by SUA ( p = 0.015) and that the effect of SUA on PWV was totally mediated by HOMA-index ( p < 0.001). Both SUA ( p < 0.01) and HOMA-index ( p < 0.01) had a significant association with higher SBP (DBP) z- scores. The double mediation model including both BP and HOMA-index showed that the SUA effect on PWV was totally mediated by both variables ( p = 0.005, for HOMA-index, p = 0.004, for SBP z- score and p = 0.007, for combined effect). The results were superimposable when the DBP z- score replaced the SBP z- score in the model. In conclusion, insulin resistance and BP are both important mediators of the association between SUA and vascular stiffness in pediatric age., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Genovesi, Montelisciani, Viazzi, Giussani, Lieti, Patti, Orlando, Antolini, Salvi and Parati.)

The improvement of hematopoietic stem and progenitor cell (HSPC) engraftment remains a high-priority goal when limited cell doses are available, such as in cord blood (CB) transplantation and HSC gene therapy. We observed that monocytes are highly effective at improving the engraftment of both CB-CD34 + and lentivirus-transfected CD34 + cells in a xenogeneic model of HSC transplantation. Moreover, monocytes, in particular the CD14 + CD16 - classical subset, in co-culture systems increase survival and stemness of CB-CD34 + cells. Both soluble factors and direct-cell contact interactions, such as JAG/NOTCH and COX-2/PGE2 pathways, are critically involved in the HSC-monocyte crosstalk. Our results indicate that the infusion of monocytes improves engraftment when cell dose is a limiting factor., (© 2022. The Author(s), under exclusive licence to Springer Nature Limited.)

The recognition code between transcription factor (TF) amino acids and DNA bases remains poorly understood. Here, the determinants of TF amino acid-DNA base binding selectivity were identified through the analysis of crystals of TF-DNA complexes. Selective, high-frequency interactions were identified for the vast majority of amino acid side chains ('structural code'). DNA binding specificities were then independently assessed by meta-analysis of random-mutagenesis studies of Zn finger-target DNA sequences. Selective, high-frequency interactions were identified for the majority of mutagenized residues ('mutagenesis code'). The structural code and the mutagenesis code were shown to match to a striking level of accuracy ( P  = 3.1 × 10 -33 ), suggesting the identification of fundamental rules of TF binding to DNA bases. Additional insight was gained by showing a geometry-dictated choice among DNA-binding TF residues with overlapping specificity. These findings indicate the existence of a DNA recognition mode whereby the physical-chemical characteristics of the interacting residues play a deterministic role. The discovery of this DNA recognition code advances our knowledge on fundamental features of regulation of gene expression and is expected to pave the way for integration with higher-order complexity approaches., (© The Author(s) 2022.

Background: One cause of poor outcomes in children of low-income countries affected by acute lymphoblastic leukaemia (ALL) is loss to follow-up due to abandonment of treatment. Assuming this type of loss to follow-up as independent censoring, as in standard Kaplan-Meier estimates, ignores the likely association of abandonment with biologic and socio-economic factors related to outcome. Moreover, when comparing treatment protocols adopted in different time periods, possible imbalances in patients' characteristics must be considered. We aim to compare the outcome of children enrolled in two subsequent protocols for ALL treatment (2000-2007 and 2008-2015) in Honduras, taking both dependent censoring due to abandonment of treatment and imbalances between patient characteristics into account., Methods: Marginal structural models based on inverse probability of treatment and censoring (IPTC) weighting allow the estimation of potential event-free survival (EFS) as if no abandonment of treatment occurred and the whole cohort was exposed, or not, to both protocols. An Aalen additive model and a logistic-regression model were used to build abandonment and treatment weights, respectively., Results: The two protocols recruited 514 and 717 patients. Measured baseline covariates in both protocols were gender, age, white blood cell count, central nervous system involvement, tumour histology and socio-economic status. The potential EFS is slightly higher under the more recent protocol in the first 3 years but no difference is estimated in the long period [survival difference at 5 years (95% confidence interval) = 0.1% (-0.97%; 1.13%)]. Both protocols would allow reducing the event rate by 12-13% if there was no abandonment of treatment., Conclusions: Using IPTC weighting, we found a similar potential effect of the two treatment protocols if the imbalance due to the different distribution of potential confounders and to abandonment of therapy was removed., (© The Author(s) 2021; all rights reserved.

Introduction: The term placenta praevia defines a placenta that lies over the internal os, whereas the term low-lying placenta identifies a placenta that is partially implanted in the lower uterine segment with the inferior placental edge located at 1-20 mm from the internal cervical os (internal-os-distance). The most appropriate mode of birth in women with low-lying placenta is still controversial, with the majority of them undergoing caesarean section. The current project aims to evaluate the rate of vaginal birth and caesarean section in labour due to bleeding by offering a trial of labour to all women with an internal-os-distance >5 mm as assessed by transvaginal sonography in the late third trimester., Methods and Analysis: The MODEL-PLACENTA is a prospective, multicentre, 1:3 matched case-control study involving 17 Maternity Units across Lombardy and Emilia-Romagna regions, Italy. The study includes women with a placenta located in the lower uterine segment at the second trimester scan. Women with a normally located placenta will be enrolled as controls. A sample size of 30 women with an internal-os-distance >5 mm at the late third trimester scan is needed at each participating Unit. Since the incidence of low-lying placenta decreases from 2% in the second trimester to 0.4% at the end of pregnancy, 150 women should be recruited at each centre at the second trimester scan. A vaginal birth rate ≥60% in women with an internal-os-distance >5 mm will be considered appropriate to start routinely admitting to labour these women., Ethics and Dissemination: Ethical approval for the study was given by the Brianza Ethics Committee (No 3157, 2019). Written informed consent will be obtained from study participants. Results will be disseminated by publication in peer-reviewed journals and presentation in international conferences., Trial Registration Number: NCT04827433 (pre-results stage)., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.

Background and Objectives: The goal of this work was to investigate the natural history and outcomes after treatment for spontaneous amyloid-related imaging abnormalities (ARIA)-like in cerebral amyloid angiopathy-related inflammation (CAA-ri)., Methods: This was a multicenter, hospital-based, longitudinal, prospective observational study of inpatients meeting CAA-ri diagnostic criteria recruited through the Inflammatory Cerebral Amyloid Angiopathy and Alzheimer's Disease βiomarkers International Network from January 2013 to March 2017. A protocol for systematic data collection at first-ever presentation and at subsequent in-person visits, including T1-weighted, gradient recalled echo-T2*, fluid-suppressed T2-weighted (fluid-attenuated inversion recovery), and T1 postgadolinium contrast-enhanced images acquired on 1.5T MRI, was used at the 3-, 6-, 12-, and 24-month follow-up. Centralized reads of MRIs were performed by investigators blinded to clinical, therapeutic, and time-point information. Main outcomes were survival, clinical and radiologic recovery, intracerebral hemorrhage (ICH), and recurrence of CAA-ri., Results: The study enrolled 113 participants (10.6% definite, 71.7% probable, and 17.7% possible CAA-ri). Their mean age was 72.9 years; 43.4% were female; 37.1% were APOE ε4 carriers; 36.3% had a history of Alzheimer disease; and 33.6% had a history of ICH. A history of ICH and the occurrence of new ICH at follow-up were more common in patients with cortical superficial siderosis at baseline (52.6% vs 14.3%, p < 0.0001 and 19.3% vs 3.6%, p < 0.009, respectively). After the first-ever presentation of CAA-ri, 70.3% (95% confidence interval [CI] 61.6%-78.5%) and 84.1% (95% CI 76.2%-90.6%) clinically recovered within 3 and 12 months, followed by radiologic recovery in 45.1% (95% CI 36.4%-54.8%) and 77.4% (95% CI 67.7%-85.9%), respectively. After clinicoradiologic resolution of the first-ever episode, 38.3% (95% CI 22.9%-59.2%) had at least 1 recurrence within the following 24 months. Recurrence was more likely if IV high-dose corticosteroid pulse therapy was suddenly stopped compared to slow oral tapering off (hazard ratio 4.68, 95% CI 1.57-13.93; p = 0.006)., Discussion: These results from the largest longitudinal cohort registry of patients with CAA-ri support the transient and potentially relapsing inflammatory nature of the clinical-radiologic acute manifestations of the disease and the effectiveness of slow oral tapering off after IV corticosteroid pulse therapy in preventing recurrences. Our results highlight the importance of differential diagnosis for spontaneous ARIA-like events in β-amyloid-driven diseases, including treatment-related ARIA in patients with Alzheimer disease exposed to immunotherapy drugs., (Copyright © 2021 The Author(s).

Aim: To evaluate mothers' satisfaction with childbirth experience in a cohort of women who delivered during COVID pandemia and to compare them to a pre-COVID cohort., Design: We performed a cross-sectional study in a low-risk Maternity Unit., Methods: Women who delivered during COVID-19 pandemic were compared to a pre-COVID cohort recruited in 2018 in the same setting. Italian version of the Birth Satisfaction Scale-Revised (I-BSS-R) was used., Results: Three hundred and seventy-seven women were included (277 pre-COVID and 100 during COVID pandemic). No differences in terms of satisfaction at birth were reported (I-BSS-R mean 27.0, SD 5.3 versus mean 27.6, SD 6.1, p 0.34), despite an increased rate of active intrapartum interventions. Intrapartum variables that significantly reduced satisfaction were the same in the two groups: epidural analgesia (p < .0001 in both groups), prolonged active phases (p < .0001 in both), oxytocin administration (p < .0001 in both) and operative delivery (p 0.0009 versus p 0.0019)., (© 2021 The Authors.

Background: Human milk is the best nutrition for all infants. When this is not available, the use of donor human milk through human milk banks (HMBs), is recommended. The aim of the study is to explore Italian women's knowledge and attitude towards human milk donation and HMB., Methods: A web-based self-administered 20-item questionnaire was developed based on the literature review and distributed via the social networking site Facebook., Results: 3290 women completed the survey. Of those 76.57% knew about the opportunity to donate human milk and 72.37% were aware of the existence of HMBs, most of them breastfed for more than 6 months. Altruism towards other mothers and having an abundant milk supply, were found to be the most important facilitators that should lead women to donate their own milk. The most important barrier was lack of information (91.25%). A high rate of women who breastfed longer than 6 months expressed issues related to collection and transportation; concerns regarding the time needed to express was reported mainly by women currently breastfeeding., Conclusions: This is the first Italian study to investigate this topic. Advertising to inform the general public should be used to increase awareness, short sessions within the school programme might sensitize women from a very young age. Healthcare professionals should strive to divulgate appropriate information.

We recently reported that activation of Trop-2 through its cleavage at R87-T88 by ADAM10 underlies Trop-2-driven progression of colon cancer. However, the mechanism of action and pathological impact of Trop-2 in metastatic diffusion remain unexplored. Through searches for molecular determinants of cancer metastasis, we identified TROP2 as unique in its up-regulation across independent colon cancer metastasis models. Overexpression of wild-type Trop-2 in KM12SM human colon cancer cells increased liver metastasis rates in vivo in immunosuppressed mice. Metastatic growth was further enhanced by a tail-less, activated ΔcytoTrop-2 mutant, indicating the Trop-2 tail as a pivotal inhibitory signaling element. In primary tumors and metastases, transcriptome analysis showed no down-regulation of CDH1 by transcription factors for epithelial-to-mesenchymal transition, thus suggesting that the pro-metastatic activity of Trop-2 is through alternative mechanisms. Trop-2 can tightly interact with ADAM10. Here, Trop-2 bound E-cadherin and stimulated ADAM10-mediated proteolytic cleavage of E-cadherin intracellular domain. This induced detachment of E-cadherin from β-actin, and loss of cell-cell adhesion, acquisition of invasive capability, and membrane-driven activation of β-catenin signaling, which were further enhanced by the ΔcytoTrop-2 mutant. This Trop-2/E-cadherin/β-catenin program led to anti-apoptotic signaling, increased cell migration, and enhanced cancer-cell survival. In patients with colon cancer, activation of this Trop-2-centered program led to significantly reduced relapse-free and overall survival, indicating a major impact on progression to metastatic disease. Recently, the anti-Trop-2 mAb Sacituzumab govitecan-hziy was shown to be active against metastatic breast cancer. Our findings define the key relevance of Trop-2 as a target in metastatic colon cancer., (Copyright © 2021. Published by Elsevier Inc.)

Background: Acute decompensated heart failure (ADHF) complicated by cardiogenic shock (CS) has unique pathophysiological background requiring specific patient stratification, management and therapeutic targets. Accordingly, the aim of this study was to derive a simple stratification tool to predict survival in patients with ADHF complicated by CS., Methods and Results: Using logistic regression, univariable testing was performed to identify the variables potentially associated with 28-day mortality. We propose a new logistic model (ALC-Shock score) based on three easy parameters (age, serum creatinine and serum lactate at the ICU admission) as a powerful predictor of survival or successful bridge to heart replacement therapy at 28-day follow-up in this specific population. A multivariable analysis (logistic model) was performed to evaluate the association between selected variables and outcome (overall death at 28-day follow up). The score was then validated in a different cohort of 93 ADHF-CS patients and compared to a previous developed score (the Cardshock score).Overall, 28-day mortality was 34%. The ALC-shock score showed better discrimination (Area Under the Curve-AUC- 0.82; 95% CI 0.73-0.91) as compared to the Cardshock score (AUC 0.67; 95% CI 0.55-0.79) (p = 0.009) to predict 28-days overall mortality. In the validation cohort the AUC for the ALC-shock score was 0.66., Conclusions: A simple score including age, lactates and creatinine on admission could be considered to predict short-term mortality in CS-ADHF patients in order to drive towards a treatment intensification., (© 2021 The Author(s).)

Rationale: Treatment with noninvasive ventilation (NIV) in coronavirus disease (COVID-19) is frequent. Shortage of intensive care unit (ICU) beds led clinicians to deliver NIV also outside ICUs. Data about the use of NIV in COVID-19 is limited. Objectives: To describe the prevalence and clinical characteristics of patients with COVID-19 treated with NIV outside the ICUs. To investigate the factors associated with NIV failure (need for intubation or death). Methods: In this prospective, single-day observational study, we enrolled adult patients with COVID-19 who were treated with NIV outside the ICU from 31 hospitals in Lombardy, Italy. Results: We collected data on demographic and clinical characteristics, ventilatory management, and patient outcomes. Of 8,753 patients with COVID-19 present in the hospitals on the study day, 909 (10%) were receiving NIV outside the ICU. A majority of patients (778/909; 85%) patients were treated with continuous positive airway pressure (CPAP), which was delivered by helmet in 617 (68%) patients. NIV failed in 300 patients (37.6%), whereas 498 (62.4%) patients were discharged alive without intubation. Overall mortality was 25%. NIV failure occurred in 152/284 (53%) patients with an arterial oxygen pressure (Pa O 2 )/fraction of inspired oxygen (Fi O 2 ) ratio <150 mm Hg. Higher C-reactive protein and lower Pa O 2 /Fi O 2 and platelet counts were independently associated with increased risk of NIV failure. Conclusions: The use of NIV outside the ICUs was common in COVID-19, with a predominant use of helmet CPAP, with a rate of success >60% and close to 75% in full-treatment patients. C-reactive protein, Pa O 2 /Fi O 2 , and platelet counts were independently associated with increased risk of NIV failure.Clinical trial registered with ClinicalTrials.gov (NCT04382235).

Background: The experience of labour and birth is complex, multidimensional and subjective and has the potential to affect the women and their families physically and emotionally. However, there is a lack of research around maternal satisfaction in Italy., Aim: To evaluate mothers' satisfaction with their childbirth experience in relation to socio-demographic characteristics, obstetric history and intrapartum care variables., Methods: A cross-sectional study involving 277 women who had given birth in a low risk maternity unit in Northern Italy was undertaken. Satisfaction with birth was measured using the Italian version of the Birth Satisfaction Scale-Revised (I-BSS-R). The scale comprises three Sub-Scales: quality of care provided, personal attributes of women and stress experienced during childbirth., Findings: No socio-demographic variables were related to maternal satisfaction. Multiparous women had a higher satisfaction score (p=0.020; CI:0.23;2.75). Antenatal class attendance was negatively associated with maternal satisfaction (p=0.038; CI:-2.58; -0.07). Intrapartum variables that significantly reduced maternal satisfaction were: epidural usage (p=0.000; CI:-4.66; -2.07), active phase >12h (p=0.000; CI:-6.01; -2.63), oxytocin administration (p=0.000; CI:-5.08; -2.29) and vacuum assisted birth (p=0.001; CI:-6.50; -1.58). Women with an intact perineum were more likely to be satisfied (p=0.008; CI:-4.60; -0.69)., Discussion: In accordance with other research, we showed that intrapartum interventions are negatively associated with maternal outcomes and therefore also with maternal satisfaction with birth. The sub-scale that measured Quality of Care provided scored higher than the other two Sub-Scales., Conclusion: Further studies on maternal satisfaction in Italy should be conducted, using the I-BSS-R with the aim to compare outcomes and understand what matters to women during childbirth., (Copyright © 2020 Australian College of Midwives.

There is limited information on the prevalence of dyslipidemia in the Italian pediatric population. Aim of the study was to evaluate total cholesterol, high-density lipoprotein (HDL)-cholesterol and triglyceride levels, and associated factors in a large sample of Italian children, applying a micro-sampling procedure in the family pediatrician's office. In a population of 1910 children (50.2% males, age 7-11 years), 27.6% was overweight or obese and 28.3% had at least one parent with referred hypercholesterolemia. Total cholesterol and triglyceride levels were elevated in 4.5% and 23.5% of the subjects, respectively, while HDL cholesterol was below 40 mg/dl in 3.3%. Male gender (OR 1.58, 95% CI 1.01-2.49) and positive family history (OR 2.13, 95% CI 1.36-3.32) were independent predictors of hypercholesterolemia, while BMI z-score was associated with low HDL cholesterol (OR 1.46, 95% CI 1.13-1.88) and high levels of triglycerides (OR 1.39, 95% CI 1.26-1.55).Conclusion: The prevalence of dyslipidemia in our sample is worthy of attention. The study suggests the opportunity and feasibility to check for the presence of dyslipidemia at the family pediatrician's office. Familiarity is associated with high cholesterol levels, regardless of the children's weight class, while weight excess identifies subjects with the typical lipid profile of metabolic syndrome. What is Known: • Few data are available on the lipid profile in Italian children. • Early treatment of hypercholesterolemia is effective in reducing cardiovascular events later in life; there is no agreement on how to screen for dyslipidemia in childhood, however. What is New: • In a large sample of Italian children, familiarity doubles the risk of hypercholesterolemia, while increased BMI is associated with low HDL cholesterol levels and hypertriglyceridemia. • The pediatrician may perform an assessment of plasma lipids in his office as a first step to diagnose familial hypercholesterolemia.

Background: The COVID-19 pandemic is challenging advanced health systems, which are dealing with an overwhelming number of patients in need of intensive care for respiratory failure, often requiring intubation. Prone positioning in intubated patients is known to reduce mortality in moderate-to-severe acute respiratory distress syndrome. We aimed to investigate feasibility and effect on gas exchange of prone positioning in awake, non-intubated patients with COVID-19-related pneumonia., Methods: In this prospective, feasibility, cohort study, patients aged 18-75 years with a confirmed diagnosis of COVID-19-related pneumonia receiving supplemental oxygen or non-invasive continuous positive airway pressure were recruited from San Gerardo Hospital, Monza, Italy. We collected baseline data on demographics, anthropometrics, arterial blood gas, and ventilation parameters. After baseline data collection, patients were helped into the prone position, which was maintained for a minimum duration of 3 h. Clinical data were re-collected 10 min after prone positioning and 1 h after returning to the supine position. The main study outcome was the variation in oxygenation (partial pressure of oxygen [PaO 2 ]/fractional concentration of oxygen in inspired air [FiO 2 ]) between baseline and resupination, as an index of pulmonary recruitment. This study is registered on ClinicalTrials.gov, NCT04365959, and is now complete., Findings: Between March 20 and April 9, 2020, we enrolled 56 patients, of whom 44 (79%) were male; the mean age was 57·4 years (SD 7·4) and the mean BMI was 27·5 kg/m 2 (3·7). Prone positioning was feasible (ie, maintained for at least 3 h) in 47 patients (83·9% [95% CI 71·7 to 92·4]). Oxygenation substantially improved from supine to prone positioning (PaO 2 /FiO 2 ratio 180·5 mm Hg [SD 76·6] in supine position vs 285·5 mm Hg [112·9] in prone position; p<0·0001). After resupination, improved oxygenation was maintained in 23 patients (50·0% [95% CI 34·9-65·1]; ie, responders); however, this improvement was on average not significant compared with before prone positioning (PaO 2 /FiO 2 ratio 192·9 mm Hg [100·9] 1 h after resupination; p=0·29). Patients who maintained increased oxygenation had increased levels of inflammatory markers (C-reactive protein: 12·7 mg/L [SD 6·9] in responders vs 8·4 mg/L [6·2] in non-responders; and platelets: 241·1 × 10 3 /μL [101·9] vs 319·8 × 10 3 /μL [120·6]) and shorter time between admission to hospital and prone positioning (2·7 days [SD 2·1] in responders vs 4·6 days [3·7] in non-responders) than did those for whom improved oxygenation was not maintained. 13 (28%) of 46 patients were eventually intubated, seven (30%) of 23 responders and six (26%) of 23 non-responders (p=0·74). Five patients died during follow-up due to underlying disease, unrelated to study procedure., Interpretation: Prone positioning was feasible and effective in rapidly ameliorating blood oxygenation in awake patients with COVID-19-related pneumonia requiring oxygen supplementation. The effect was maintained after resupination in half of the patients. Further studies are warranted to ascertain the potential benefit of this technique in improving final respiratory and global outcomes., Funding: University of Milan-Bicocca., (Copyright © 2020 Elsevier Ltd.

Precise risk factors for bleeding after pancreatoduodenectomy (PD) need to be further explored. We aimed to identify which variables were associated with the risk of post-pancreatectomy hemorrhage (PPH) and benchmark the PPH rate and related outcome in our intermediate-volume center with the current literature. We retrospectively analyzed 183 PD records. We investigated the association between PPH and a number of pre-surgical (age, body mass index, bilirubin plasma level, gender, American Society of Anesthesiologists classification (ASA) and smoking status, vascular hypertension), surgical (technique, additional organ resection, occlusion of the stump) and post-surgical (pancreatic fistula, bile leak and abscess development) risk factors with multivariable regression models. PPH episodes were classified and graded according to the International Study Group of Pancreatic Surgery. The overall PPH risk was 19.6%. Specific PPH mortality was 16.6%. Occurrence of PPH was increased in male patients (RR = 2.4, p = 0.001), with ASA ≥ 3 (RR = 2.1, p = 0.009) and hypertension (RR = 1.8, p = 0.04). Active smoking was protective (RR = 0.26, p = 0.001). Among postoperative factors, only pancreatic fistula increased the risk (RR = 1.6, p = 0.034). Early PPH was associated with the type of surgical reconstruction (RR 4.02, 95% CI 1.41-11.44, p = 0.009) and late PPH with pancreatic fistula (RR 2.88, 95% CI 1.06-7.83, p = 0.038). For grade C PPH, the impact of pancreatic fistula was greater (RR = 2.8, p = 0.04). Pancreatic fistula plays a crucial role in the pathogenesis of PPH. In addition, male gender, ASA ≥ 3 and hypertension increase the risk of PPH, while smoking appears protective. The PPH risk and subsequent consequences are at an acceptable rate in an intermediate-volume center.

Objective and Methods: The study aimed at evaluating, in a large sample of Italian children, the reclassification of blood pressure categories with the new U.S. nomograms, obtained in a population of normal-weight children (American Academy of Pediatrics Clinical Practice Guidelines, AAP-CPG), compared with the Fourth Report/European Society of Hypertension (ESH) nomograms. The performance of the two classifications in identifying the presence of left ventricular hypertrophy was also assessed., Results: In 951 individuals referred to a Pediatric Center for Cardiovascular Risk Prevention, a 12% increase in the prevalence of children with blood pressure at least 90th percentile was observed by using the new nomograms. In the subsample of children aged at least 13 years, the application of the blood pressure fixed cutoff values of 120/<80 mmHg (for 'elevated' blood pressure) and of 130/80 mmHg (for hypertension) led to a change in the blood pressure category (worse or better) in about 30% of cases as compared with the AAP-CPG classification based on percentiles. Regarding the identification of individuals with left ventricular hypertrophy, the AAP-CPG classification led to an increase in the true positive fraction (sensitivity) of 5.5%, and to an increment of the false-positive fraction (1 - specificity) of 5.8%. The logistic regression model, adjusted for possible confounding factors, and the ROC curves obtained from the linear predictor of the model showed an identical performance of the Fourth Report/ESH and the AAP-CPG classifications., Conclusion: In our paediatric population, the AAP-CPG classification slightly increased the prevalence of elevated blood pressure values compared with the Fourth Report/ESH classification. Moreover, the application of more 'physiological' nomograms, based on a population of normal-weight children, did not yield any advantage in identifying individuals with early cardiac organ damage.

Introduction: Acute coronary syndromes (ACS) have been classified according to the finding of ST-segment elevation on the presenting electrocardiogram, with different treatment strategies and practice guidelines. However, a comparative description of the clinical characteristics and outcomes of acute coronary syndrome elderly patients undergoing percutaneous coronary intervention during index admission has not been published so far., Methods: Retrospective cohort study of patients enrolled in the Elderly ACS-2 multicenter randomized trial. Main outcome measures were crude cumulative incidence and cause-specific hazard ratio (cHR) of cardiovascular death, noncardiovascular death, reinfarction, and stroke., Results: Of 1443 ACS patients aged >75 years (median age 80 years, interquartile range 77-84), 41% were classified as ST-elevation myocardial infarction (STEMI), and 59% had non-ST-elevation ACS (NSTEACS) (48% NSTEMI and 11% unstable angina). As compared with those with NSTEACS, STEMI patients had more favorable baseline risk factors, fewer prior cardiovascular events, and less severe coronary disease, but lower ejection fraction (45% vs 50%, P < .001). At a median follow-up of 12 months, 51 (8.6%) STEMI patients had died, vs 39 (4.6%) NSTEACS patients. After adjusting for sex, age, and previous myocardial infarction, the hazard among the STEMI group was significantly higher for cardiovascular death (cHR 1.85; 95% confidence interval [CI], 1.02-3.36), noncardiovascular death (cHR 2.10; 95% CI, 1.01-4.38), and stroke (cHR 4.8; 95% CI, 1.7-13.7)., Conclusions: Despite more favorable baseline characteristics, elderly STEMI patients have worse survival and a higher risk of stroke compared with NSTEACS patients after percutaneous coronary intervention., (Copyright © 2018.

Objective: To determine plasma aldosterone concentration (PAC) and plasma renin concentration (PRC) and aldosterone-to-renin ratio (ARR) values in a population attending a Clinic for Cardiovascular Risk Assessment in Children., Methods: We assessed ARR and associated factors in a cohort of 287 children (137 female, 4-18 years). Weight and blood pressure (BP) were recorded. PAC (ng/dl) and PRC (mU/l) were measured using direct immunochemiluminescent assays. Data were examined by sex and according to four age classes., Results: Median PAC was similar from the youngest to the oldest age class ranging from 7.5 to 9.9 ng/dl in males and from 11.0 to 12.6 ng/dl in females. Median PRC was also similar across age classes in males ranging from 58.2 to 55.5 mU/l, whereas it progressively decreased from 61.5 to 36.6 mU/l in females (P < 0.01). Median PRC was higher in prepubertal than in pubertal females only (53.6 vs. 40.2 mU/l, P < 0.03). As a result ARR was unchanged with increasing age in males (from 0.18 to 0.19), whereas in females it increased from 0.19 to 0.36 (P < 0.03). After adjusting for body weight, BP and other possible confounders, age was inversely related with PRC and directly with PAC and ARR (P < 0.001 for all), in females only. No relationship was found in both sexes between ARR values, BP, weight and family history of hypertension., Conclusion: In our children population, ARR is lower than in adults and diverges with increasing age between sexes, due to the age and puberty driven fall in PRC observed only in females. BP and weight are not associated with ARR distribution.

Anaplastic lymphoma kinase (ALK)-positive lymphomas respond to chemotherapy, but relapses, which bear a poor prognosis, occur. Crizotinib inhibits ALK in vitro and in vivo and was administered as monotherapy to 11 ALK+ lymphoma patients who were resistant/refractory to cytotoxic therapy. The overall response rate was 10 of 11 (90.9%; 95% confidence interval [CI] = 58.7% to 99.8%). Disease status at the latest follow-up is as follows: four patients are in complete response (CR) (months >21, >30, >35, >40) under continuous crizotinib administration; 4 patients had progression of disease (months 1, 2, 2, 2); 1 patient obtained CR on crizotinib, received an allogeneic bone marrow transplant, and is in CR; 2 patients (treated before and/or after allogeneic bone marrow transplant) obtained and are still in CR but they have stopped crizotinib. Overall and progression-free survival rates at 2 years are 72.7% (95% CI = 39.1% to 94.0%) and 63.7% (95% CI = 30.8% to 89.1%), respectively. ALK mutations conferring resistance to crizotinib in vitro could be identified in relapsed patients. Crizotinib exerted a potent antitumor activity with durable responses in advanced, heavily pretreated ALK+ lymphoma patients, with a benign safety profile.

Aim: To asses the value of computed tomography (CT)-perfusion in the detection of residual hepatocellular carcinoma (HCC) vascularization after transarterial chemoembolization (TACE)., Methods: Thirty-two consecutive patients were prospectively included in this study. All patients had liver cirrhosis and a confirmed HCC lesion which was treated with TACE. One month after treatment, perfusion measurements of treated lesions were carried out. The CT-perfusion (CT-p) protocol was performed with 16 slice multidetector computed tomography which included the following parameters: 8 dynamic slices/scan per 40 scans after iv injection of 50 mL of iodinated contrast (350 mg/mL) at a flow rate of 6 mL/s. Treated lesions were evaluated using dedicated perfusion software, which generated a quantitative colour map of perfusion. The following parameters were considered: hepatic perfusion (HP), arterial perfusion (AP), blood volume (BV), hepatic perfusion index (HPI), and time to peak (TTP). Perfusion parameters were described with quartile values of their distribution and statistically analyzed., Results: Perfusion parameters of the treated lesions could be quantitatively assessed using CT-p analysis. The presence of residual tumor tissue was observed in 13 of the 32 patients. The values of the perfusion parameters measured within the relapse tissue were: HP (mL/100 g per minute): median = 44.4 (1(st)qt = 31.3, 3(rd)qt = 55.8); BV (mL/100 g): median = 18.7 (1(st)qt = 11.5, 3(rd)qt = 22.5); AP (mL/min): median = 39.0 (1(st)qt = 36.5, 3(rd)qt = 61.3); HPI (%): median = 34.0 (1(st)qt = 30.4, 3(rd)qt = 38.9); TTP (s): median = 17.3 (1(st)qt = 15.8, 3(rd)qt = 26.5). With the use of the univariate paired Wilcoxon signed rank test, HP, AP and HPI were shown to be significantly higher (P < 0.001) in the relapse site than in the primary lesion. The BV and TTP parameters showed a tendency to be greater and lower, respectively, in the relapse site than in the primary lesion., Conclusion: In patients with HCC treated with TACE, CT-p provides measurement of flow parameters related to residual arterial structures in viable tumor, thus helping in the assessment of therapeutic response.
