Prognostic role of minimal residual disease before and after hematopoietic stem cell transplantation in childhood acute lymphoblastic leukemia

More than 80% of children with acute lymphoblastic leukemia (ALL) can be cured through intensive and risk-oriented chemotherapy protocols. Allogeneic hematopoietic stem cell transplantation (HSCT) is considered bene\ufb01cial for approximately 10% of the patients who are at veryhigh risk at frontline therapy and for the majority of patients after relapse. Consequently, it is critically important to identify prognostic factors in this group of patients in order to tailor risk-adapted therapy. In this retrospective study, we aimed to assess the prognostic role of minimal residual disease (MRD) before HSCT and at di\ufb00erent time points after transplantation in children with ALL

Long-term continuous monitoring of the preterm brain with diffuse optical tomography and electroencephalography: A technical note on cap manufacturing

open12noDiffuse optical tomography (DOT) has recently proved useful for detecting whole-brain oxygenation changes in preterm and term newborns' brains. The data recording phase in prior explorations was limited up to a maximum of a couple of hours, a time dictated by the need to minimize skin damage caused by the protracted contact with optode holders and interference with concomitant clinical/nursing procedures. In an attempt to extend the data recording phase, we developed a new custom-made cap for multimodal DOT and electroencephalography acquisitions for the neonatal population. The cap was tested on a preterm neonate (28 weeks gestation) for a 7-day continuous monitoring period. The cap was well tolerated by the neonate, who did not suffer any evident discomfort and/or skin damage. Montage and data acquisition using our cap was operated by an attending nurse with no difficulty. DOT data quality was remarkable, with an average of 92% of reliable channels, characterized by the clear presence of the heartbeat in most of them.openopenAlfonso Galderisi; Sabrina Brigadoi; Simone Cutini; Sara Basso Moro; Elisabetta Lolli; Federica Meconi; Silvia Benavides-Varela; Eugenio Baraldi; Piero Amodio; Claudio Cobelli; Daniele Trevisanuto; Roberto Dell'AcquaGalderisi, Alfonso; Brigadoi, Sabrina; Cutini, Simone; BASSO MORO, Sara; Lolli, Elisabetta; Meconi, Federica; Silvia, Benavides-Varela; Baraldi, Eugenio; Amodio, Piero; Cobelli, Claudio; Trevisanuto, Daniele; Dell'Acqua, Robert

Fertility Preservation in Female Cancer Patients

With improved survival rates among cancer patients, fertility preservation is now being recognized as an issue of great importance. There are currently several methods of fertility preservation available in female cancer patients and the options and techniques via assisted reproduction and cryopreservation are increasing, but some are still experimental and continues to be evaluated. The established means of preserving fertility include embryo cryopreservation, gonadal shielding during radiation therapy, ovarian transposition, conservative gynecologic surgery such as radical trachelectomy, donor embryos/oocytes, gestational surrogacy, and adoption. The experimental methods include oocyte cryopreservation, ovarian cryopreservation and transplantation, in vitro maturation, and ovarian suppression. With advances in methods for the preservation of fertility, providing information about risk of infertility and possible options of fertility preservation to all young patients with cancer, and discussing future fertility with them should be also considered as one of the important parts of consultation at the time of cancer diagnosis

A Thorough Study on the Photoisomerization of Ferulic Acid Derivatives

AbstractA thorough study on the (E) to (Z) photoisomerization of ferulic acid derivatives (esters, amides of all types, and ketones) was carried out. At the photostationary state, only aliphatic or benzylic tertiary amides reach a nearly complete conversion of (E) isomers into the (Z) ones, whereas for esters, primary and secondary amides or aromatic tertiary amides mixtures of (Z)/(E) ranging from 7 : 93 to 72 : 28 are observed. Ketones show rather limited photoisomerization. However, (Z) ketones may be obtained by the reaction of organometal compounds with an isomerized (Z) Weinreb amide

Experimental priming of encephalitogenic Th1/Th17 cells requires pertussis toxin-driven IL-1 beta production by myeloid cells

CD4(+) Th17 are heterogeneous in terms of cytokine production and capacity to initiate autoimmune diseases, such as experimental autoimmune encephalomyelitis (EAE). Here we demonstrate that experimental priming of encephalitogenic Th cells expressing ROR gamma t and T-bet and producing IL-17A, IFN-gamma and GM-CSF but not IL-10 (Th1/Th17), is dependent on the presence of pertussis toxin (PTX) at the time of immunization. PTX induces early production of IL-1 beta by CD11b(+)CCR2(+)Gr1(+) myeloid cells, which are rapidly recruited to antigen-draining lymph nodes. PTX-induced generation of Th1/Th17 cells is impaired in IL-1 beta- and ASC-deficient mice and in mice in which myeloid cells are depleted or fail to migrate to lymph nodes and requires expression of IL-1R1 and MyD88 on both T cells and non-T cells. Collectively, these data shed light on the enigmatic function of PTX in EAE induction and suggest that inflammatory monocytes and microbial infection can influence differentiation of pathogenic Th1/Th17 cells in autoimmune diseases through production of IL-1 beta

Factors influencing choice of chemotherapy in metastatic colorectal cancer (mCRC)

Management of metastatic colorectal cancer requires a multimodal approach and must be performed by an experienced, multidisciplinary expert team. The optimal choice of the individual treatment modality, according to disease localization and extent, tumor biology, and patient clinical characteristics, will be one that can maintain quality of life and long-term survival, and even cure selected patients. This review is an overview of the different therapeutic approaches available in metastatic colorectal cancer, for the purpose of defining personalized therapeutic algorithms according to tumor biology and patient clinical features

Aquileia and its urban development in the light of recent and ongoing research

Our knowledge regarding the urban planning of Aquileia and its development has significantly increased since the publication of the last comprehensive overview of this subject in the volume Aquileia moenibus et portu celeberrima in 2009. Indeed, over the previous decade, several new research projects have shone new light on the urban planning, function, and development of Aquileia, adding much new data and evidence to our overall knowledge of the ancient colony and Adriatic emporium. This paper presents the most significant results of recent investigations, providing a first updated overview of the city’s urban development, focusing and commenting on the following themes: city walls and town planning, Forum and river port, entertainment and recreational buildings (theatre, amphitheatre and Imperial baths), commercial areas and complexes, private spaces and townhouses

SARS-CoV-2 Circulation in the School Setting: A Systematic Review and Meta-Analysis

The contribution of children to viral spread in schools is still debated. We conducted a systematic review and meta-analysis of studies to investigate SARS-CoV-2 transmission in the school setting. Literature searches on 15 May 2021 yielded a total of 1088 publications, including screening, contact tracing, and seroprevalence studies. MOOSE guidelines were followed, and data were analyzed using random-effects models. From screening studies involving more than 120,000 subjects, we estimated 0.31% (95% confidence interval (CI) 0.05–0.81) SARS-CoV-2 point prevalence in schools. Contact tracing studies, involving a total of 112,622 contacts of children and adults, showed that onward viral transmission was limited (2.54%, 95% CI 0.76–5.31). Young index cases were found to be 74% significantly less likely than adults to favor viral spread (odds ratio (OR) 0.26, 95% CI 0.11–0.63) and less susceptible to infection (OR 0.60; 95% CI 0.25–1.47). Lastly, from seroprevalence studies, with a total of 17,879 subjects involved, we estimated that children were 43% significantly less likely than adults to test positive for antibodies (OR 0.57, 95% CI 0.49–0.68). These findings may not applied to the Omicron phase, we further planned a randomized controlled trial to verify these results
