Abstract
Inhibitors of phosphatidylinositol 3-kinase (PI3K) and Bruton tyrosine kinase (BTK) represent a recognized option for the treatment of patients affected by indolent B cell lymphomas. However, small molecules as single agents show limited success in their ability in inducing complete responses, with only partial remission achieved in most patients, suggesting the need for combination therapies. IRAK4 is a protein kinase downstream of the Toll-like receptor signaling (TLR), a driver pathway of secondary tumor° resistance in both hematological and solid tumor malignancies. Activation of IRAK4 upon TLRs and IL-1 receptor (IL-1R) stimulation and through the adaptor protein MYD88 initiates a signaling cascade that induces cytokine and survival factor expression mediated by the transcription factor NF-κB. MYD88-L265P encoding mutations occur in diffuse large B-cell lymphomas, in lymphoplasmacytic lymphomas and in few marginal zone lymphomas (MZL). The IRAK4 inhibitor emavusertib (CA-4948) has shown early safety and clinical activity in lymphoma and leukemia patients. In this preclinical study, we assessed emavusertib effectiveness in MZL, both as single agent and in combination with targeted agents, with a particular focus on its capability to overcome resistance to BTK and PI3K inhibitors. We showed that the presence of MYD88 L265P mutation in bona fide MZL cell lines confers sensitivity to the IRAK4 inhibitor emavusertib as single agent. Emavusertib-based combinations improved the sensitivity of MZL cells to BTK and PI3K inhibitors, including cells with a secondary resistance to these agents. Emavusertib exerted its activity via inhibition of NF-κB signaling and induction of apoptosis. Considering the early safety data from clinical trials, our study identifies the IRAK4 inhibitor emavusertib as a novel compound to be explored in trials for patients with MYD88-mutated indolent B cell lymphomas as single agent and as combination partner with BTK or PI3K inhibitors in unselected populations of patients.

Abstract
Splenic marginal zone B-cell lymphoma (SMZL) is a heterogeneous clinico-biological entity. The clinical course is variable, multiple genes are mutated with no unifying mechanism, and essential regulatory pathways and surrounding microenvironments are diverse. We sought to clarify the heterogeneity of SMZL by resolving different subgroups and their underlying genomic abnormalities, pathway signatures, and microenvironment compositions to uncover biomarkers and therapeutic vulnerabilities. We studied 303 SMZL spleen samples collected through the IELSG46 multicenter international study (NCT02945319) by using a multiplatform approach. We carried out genetic and phenotypic analyses, defined self-organized signatures, validated the findings in independent primary tumor metadata and in genetically modified mouse models, and determined correlations with outcome data. We identified 2 prominent genetic clusters in SMZL, termed NNK (58% of cases, harboring NF-κB, NOTCH, and KLF2 modules) and DMT (32% of cases, with DNA-damage response, MAPK, and TLR modules). Genetic aberrations in multiple genes as well as cytogenetic and immunogenetic features distinguished NNK- from DMT-SMZLs. These genetic clusters not only have distinct underpinning biology, as judged by differences in gene-expression signatures, but also different outcomes, with inferior survival in NNK-SMZLs. Digital cytometry and in situ profiling segregated 2 basic types of SMZL immune microenvironments termed immune-suppressive SMZL (50% of cases, associated with inflammatory cells and immune checkpoint activation) and immune-silent SMZL (50% of cases, associated with an immune-excluded phenotype) with distinct mutational and clinical connotations. In summary, we propose a nosology of SMZL that can implement its classification and also aid in the development of rationally targeted treatments.

Abstract
Extraction-free HTG EdgeSeq protocols are used to profile sets of genes and measure their expression. Thus, these protocols are frequently used to characterise tumours and their microenvironments. However, although positive and control genes are provided, little indication is given concerning the assessment of the technical success of each sample within the sequencing run. We developed HTGQC, an R package for the quality control of HTG EdgeSeq protocols. Additionally, shinyHTGQC is a shiny application for users without computing knowledge, providing an easy-to-use interface for data quality control and visualisation. Quality checks can be performed on the raw sequencing outputs, and samples are flagged as FAIL or ALERT based on the expression levels of the positive and negative control genes. Availability & Implementation The code is freely available at https://github.com/LodovicoTerzi/HTGQC (R package) and https://lodovico.shinyapps.io/shinyHTGQC/ (shiny application), including test datasets.

Abstract
Abstract
Background. Marginal zone lymphoma (MZL) is a heterogeneous B-cell malignancy for which no standard treatment exists. B-cell receptor (BCR) signaling dysregulation is a hallmark of MZL and can mimic antigen dependent BCR activation. However, single treatment with BCR signaling inhibitors shows limited complete response rate and relapsing patients. IRAK4 is a protein kinase downstream the Toll-like receptor signaling. CA-4948 is the first-in-class inhibitor of IRAK4 and it is in phase 1/2 studies for patients with relapsed/refractory clinical studies with favorable activity in lymphomas and myeloid neoplasms. Here, we assessed IRAK4 inhibition with CA-4948 against a panel of MZL cell lines in which we have developed secondary resistance to inhibitors of PI3K (idelalisib, copanlisib) or BTK (ibrutinib). Methods. Models with secondary resistance were developed by continuous exposing cell lines derived from splenic MZL (Karpas 1718 and VL51) to high doses of drugs for long period of times. Resistant and parental lines were exposed to increasing doses of CA-4948, alone or in combination with compounds they are resistant to. Cell viability was tested by MTT assay (72h treatment). Synergy of combinations was evaluated according to the Chou-Talalay combination index (CI), as well as potency and efficacy, estimated according to the MuSyC algorithm. Results. The parental Karpas1718, bearing a MYD88 L265P mutation, had an IC50 of 3.29 µM for CA-4948 as single agent, while the parental VL51 and all resistant models presented IC50 values in the range of 19-35 µM. IRAK4 inhibition with CA-4948 had strong benefit when combined to downstream BCR inhibitors. In resistant cells, CA-4948 was strongly synergistic with idelalisib, ibrutinib and, at lesser extent, with copanlisib. CA-4948 in combination with ibrutinib was strongly synergistic especially in the VL51 ibrutinib resistant model compared to the parental one. CA-4948 (from 1 to 5 µM) recovered sensitivity to ibrutinib at IC50 values close to the parental condition. Similarly, CA-4948 in combination with idelalisib was also synergistic and increased sensitivity to idelalisib in idelalisib resistant VL51. Less benefit was seen adding CA-4948 to copanlisib: the combination was synergistic in VL51 parental cell, but with only weak efficacy. In the Karpas1718, CA-4948 was synergistic either in idelalisib resistant or in parental, with improved benefit in the latter, in which synergistic effect was observed when combined with both idelalisib and ibrutinib. The synergistic activity of CA-4948 was mainly due to improved efficacy rather than potency of the combinatorial partners. Conclusions. Our results in MZL cell lines show that the IRAK4 inhibitor CA-4948 is synergistic with small molecules targeting BCR signaling, especially with idelalisib and ibrutinib. Data also suggest that concentrations of CA-4948 comparable to those achieved in patients might overcome or reduce secondary resistance to the tested tyrosine kinase inhibitors.

Abstract
Enhancers are regulatory regions of DNA, which play a key role in cell-type specific differentiation and development. Most active enhancers are transcribed into enhancer RNA (eRNA) that can regulate transcription of target genes by means of in cis as well as in trans action. eRNA stabilize contacts between distal genomic regions and mediate the interaction of DNA with master transcription factors. Here, we characterized an enhancer eRNA, GECPAR (germinal center proliferative adapter RNA), which is specifically transcribed in normal and neoplastic germinal center B cells from the super-enhancer of POU2AF1, a key regulatory gene of the germinal center reaction. Using diffuse large B-cell lymphoma cell line models, we demonstrated the tumor suppressor activity of GECPAR, which is mediated via its transcriptional regulation of proliferation and differentiation genes, particularly MYC and the Wnt pathway.

Abstract
Tick-borne encephalitis virus (TBEV) is an emerging human pathogen that causes potentially fatal disease with no specific treatment. Mouse monoclonal antibodies are protective against TBEV, but little is known about the human antibody response to infection. Here, we report on the human neutralizing antibody response to TBEV in a cohort of infected and vaccinated individuals. Expanded clones of memory B cells expressed closely related anti-envelope domain III (EDIII) antibodies in both groups of volunteers. However, the most potent neutralizing antibodies, with IC50s below 1 ng/ml, were found only in individuals who recovered from natural infection. These antibodies also neutralized other tick-borne flaviviruses, including Langat, louping ill, Omsk hemorrhagic fever, Kyasanur forest disease, and Powassan viruses. Structural analysis revealed a conserved epitope near the lateral ridge of EDIII adjoining the EDI-EDIII hinge region. Prophylactic or early therapeutic antibody administration was effective at low doses in mice that were lethally infected with TBEV.

Abstract
Antibody drug conjugates represent an important class of anti-cancer drugs in both solid tumors and hematological cancers. Here, we report preclinical data on the anti-tumor activity of the first-in-class antibody drug conjugate MEN1309/OBT076 targeting CD205. The study included preclinical in vitro activity screening on a large panel of cell lines, both as single agent and in combination and validation experiments on in vivo models. CD205 was first shown frequently expressed in lymphomas, leukemias and multiple myeloma by immunohistochemistry on tissue microarrays. Anti-tumor activity of MEN1309/OBT076 as single agent was then shown across 42 B-cell lymphoma cell lines with a median IC50 of 200 pM and induction of apoptosis in 25/42 (59.5%) of the cases. The activity appeared highly correlated with its target expression. After in vivo validation as the single agent, the antibody drug conjugate synergized with the BCL2 inhibitor venetoclax, and the anti-CD20 monoclonal antibody rituximab. The first-in-class antibody drug targeting CD205, MEN1309/OBT076, demonstrated strong pre-clinical anti-tumor activity in lymphoma, warranting further investigations as a single agent and in combination.

Abstract
Purpose: Activation of the PI3K/mTOR signaling pathway is recurrent in different lymphoma types, and pharmacologic inhibition of the PI3K/mTOR pathway has shown activity in lymphoma patients. Here, we extensively characterized the in vitro and in vivo activity and the mechanism of action of PQR309 (bimiralisib), a novel oral selective dual PI3K/mTOR inhibitor under clinical evaluation, in preclinical lymphoma models.Experimental Design: This study included preclinical in vitro activity screening on a large panel of cell lines, both as single agent and in combination, validation experiments on in vivo models and primary cells, proteomics and gene-expression profiling, and comparison with other signaling inhibitors.Results: PQR309 had in vitro antilymphoma activity as single agent and in combination with venetoclax, panobinostat, ibrutinib, lenalidomide, ARV-825, marizomib, and rituximab. Sensitivity to PQR309 was associated with specific baseline gene-expression features, such as high expression of transcripts coding for the BCR pathway. Combining proteomics and RNA profiling, we identified the different contribution of PQR309-induced protein phosphorylation and gene expression changes to the drug mechanism of action. Gene-expression signatures induced by PQR309 and by other signaling inhibitors largely overlapped. PQR309 showed activity in cells with primary or secondary resistance to idelalisib.Conclusions: On the basis of these results, PQR309 appeared as a novel and promising compound that is worth developing in the lymphoma setting.

Abstract
Anatomical hemispherectomy has had excellent results in treating drug-resistant seizures of infantile hemiplegia. This technique of hemispherectomy consists in the removal of a whole hemisphere, with or without the basal ganglia, the end result being a large cavity left at the end of the operation. The technique, however, is considered to be weighted by important complications, in particular intracranial hemorrhages due to vessels tearing secondary to dislodgement of the remaining hemisphere. Several techniques have been consequently proposed to reduce the volume of the residual hemicranial cavity. An alternative measure is the filling of the cavity itself. We have demonstrated that this type of procedure can be carried out using a silicone breast prosthesis. In this report, we demonstrate also that such an implant can have a surprisingly long duration in its unusual location.

Abstract
The placement of implants in the posterior maxillary area is considered a reliable procedure, offering recognized rehabilitative advantages. The aim of this study was to evaluate the performance of dental implants placed in the sinus floor augmented with a block autograft by comparing the outcomes over 5 years with those of dental implants positioned in non-augmented bone. This retrospective cohort study included 16 patients who had undergone prosthetic rehabilitation supported by dental implants between 2000 and 2006. One implant per patient was included and assigned to one of two predictor groups: grafted versus ungrafted maxillary sinus. Changes in marginal bone level (MBL) and apical bone level (ABL) over time, at 1, 3, and 5 years, were the primary outcome variables. Appropriate pair-wise comparison tests were performed. No significant differences were seen with regard to ABLs and among times between the grafted group (nine implants) and the ungrafted group (seven implants). Significant marginal bone resorption was found over time, primarily at the buccal aspect, in both study groups. The bone surrounding the apex of dental implants appeared stable after sinus augmentation in the grafted area. The behaviour of the two groups with regard to loss of MBLs over time was very similar.

Abstract
The aim of the present retrospective chart review was to determine the relationship between nonvascularized osseous graft remodeling and the three-dimensional (3D) features of grafts and recipient sites, the anatomical recipient regions and different graft sources. 32 iliac crest or chin grafts were onlay-positioned in the mandible or maxilla of 14 patients. CT scans, taken before implant positioning and after 1 year, revealed a mean volume resorption of 35-51%. For iliac crest grafts, the average resorption was 42% when the onlay was positioned in the anterior maxilla and 59% when it was positioned in the posterior mandible. Spearman correlation and 3D interpolation analysis revealed, for both iliac crest groups, a moderate or advanced remodeling pattern depending on 3D features, namely graft thickness and shape, basal bone volume of recipient site, and the basal bone/graft volume ratio of the recipient site. No statistically significant differences were found between the recipient and donor site groups. Retrospective analysis of the data indicates that iliac crest grafts, onlay-positioned on adequate basal bone volume, may register a reduced volume remodeling when shaped thick in the anterior maxilla or rounded and convex, on the external surface, in the posterior mandible.

Abstract
Evaluation and treatment of hyperglycaemic hyponatremia, being quantitatively inaccurate, is open to new advancements. We herein describe the improvement of previous calculations of glucose appearance (G(A)), solute and solvent changes. From G(A) we derive the predicted plasma sodium concentration (PNa(G)), assuming no change in total body water (TBW), but only water shift from cells to the extracellular space (ECV). This assumption is validated by the respective solute ratios (PCl/PNa) unchanged from normal values, as well as the ratios between actual and normal solute concentrations (PNa(1)/PNa(0), PCl(1)/PCl(0)), identical for all solutes. When the assumption is met, G(A) can be exactly calculated. When the ratios are different from normal, they indicate the presence of a mixed abnormality due to a loss either of sodium, or sodium and water. These are estimated by computing the difference between PNa(G) and the actual PNa measured (PNa(1)). PNa(1) approximately equal PNa(G) if TBW and Na are unchanged, PNa(1) < PNa(G) in the presence of prevalent Na depletion, PNa(1) > PNa(G )when volume depletion prevails. In the first circumstance the ECV expansion is exactly established by appropriate mathematical formulas, in the latter conditions either Na or volume depletion are empirically estimated with algebric expressions. These equations were validated on computer-simulated models, and applied to 49 subjects with plasma glucose concentration >15 mM/L. G(A) and PNa(G) were computed, and, with the same formulas used in computer-simulated experiments, we calculated water and Na deficits. The PNa measured after correction of hyperglycaemia was correctly predicted (R(2) = 0.63, P < 0.0001). This method provides a firm ground to select the correct equation to accurately estimate the initial conditions of hyperosmolar hyperglycaemia, significantly improving its quantitative correction.

Abstract
BACKGROUND The treatment of solute addition, Na and water losses in hyperglycaemic hyponatraemia is guided by clinical judgement rather than by a quantitative assessment. METHODS We devised an iteration method to compute glucose appearance (G(A)) within the extracellular space, to obtain the PNa (plasma sodium concentration) expected by glucose addition only (PNa(G)). The difference between this and the actual measurement (PNa(1)) was used to compute the attending Na and/or volume depletion, and the PNa expected during correction. The equations were validated on computer-built models, where the electrolyte derangements were simulated, generating true values of plasma glucose (P(G)) and Na concentrations, from which surfeit and deficits were back-calculated with our formulas. We also computed G(A) and PNa(G) on 43 patients who were stratified into a group with normal hydration (PNa(1) = PNa(G)), one with prevalent Na depletion (PNa(1) < PNa(G)), and one with prevalent volume depletion (PNa(1) > PNa(G)). The volume conditions established by our computations were compared by logistic regression analysis with those assessed from clinical laboratory data. RESULTS The computer simulations demonstrated that the method gave exact results when only one variable changed, clinically useful estimates in the presence of mixed volume and sodium deficits. There was a strongly significant concordance between the clinical and the quantitative method (P < 0.001). The latter predicted the PNa measured after correction of hyperglycaemia (P < 0.001). CONCLUSION This new method more accurately computes the initial conditions, resulting in a useful stratification of patients which improves the quantitative evaluation and treatment of hyperosmolar coma.

Abstract
AIMS To assess and classify exposure to Polycyclic Aromatic Hydrocarbons (PAHs) in some specific working areas of a steel foundry operating with a continuous casting process and evaluate biomonitoring data in different job tasks. METHODS Exposure to dusts and six PAHs classified as carcinogenic by EU directives was studied in a cohort of 35 male foundry workers (aged 41.1 +/- 6.9 years), who were examined both prior to and at the end of the work-shift (06:00 a.m.-02:00 p.m.) in two different periods. The urinary excretion of 1-hydroxypyrene (1-OH-P) was measured as a biomarker of exposure to pyrene. RESULTS PAHs concentrations ranged from 461.8 to 935.6 ng/m3 near the continuous casting area, whereas lower values were measured near the ladle furnace. End of shift 1-OH-P values were higher in 11 non-smoking workers involved in continuous casting process as compared to those employed in mantenance and furnace areas (median of the second determination: 5.70 microg/g creatinine--range: 1.24-21.24 vs 1.17 microg/g creatinine--range: 0.23-4.49; p< 0.001). 1-OH-P excretion was significantly correlated with both the sum of six carcinogenic PAHs and pyrene airborne concentrations. In two biomonitoring sessions, 9.1% and 34.3% of the workers respectively showed end-of-shift 1-OH-P values exceeding the occupational exposure limit (OEL) (4.4 microg/g creatinine or 2.3 micromol/mol(-1) creatinine) recommended for coke-oven workers. CONCLUSIONS 1-OH-P is a useful biomarker in assessing PAH exposure and is associated with job category at a Steelplant. Due to exposure variability, to assess risk associated with PAHs exposure, biological monitoring should be carried out periodically.

Abstract
BACKGROUND AND OBJECTIVES Clonal hematopoiesis is the hallmark of myelodysplastic syndromes, but the role played by pluripotent stem cells and progenitor cells in these disorders remains unclear. DESIGN AND METHODS Eight female patients with myelodysplastic syndrome were studied. X-chromosome inactivation patterns were analyzed in peripheral blood granulocytes, T-lymphocytes, single colonies originating from bone marrow progenitors and pluripotent stem cells, using the human androgen receptor locus polymorphism assay. RESULTS Granulocytes and progenitor cells were monoclonal in 7/8 cases. Immature stem cells showed a non-clonal pattern of X-inactivation and were detectable at diagnosis in the presence of clonal hematopoiesis. T-lymphocyte clonality was heterogeneous. INTERPRETATION AND CONCLUSIONS In myelodysplastic syndromes, hematopoiesis may be dominated by a neoplastic clone by virtue of its biological advantage over a residual polyclonal, probably still normal, population of immature stem cells still able to grow in vitro.

Abstract
Primary lymphomatous effusions are defined as lymphomas presenting in the serous body cavities in the absence of clinically identifiable tumor masses. Recently, a peculiar type of primary lymphomatous effusion associated with tumor clone infection by human herpesvirus type 8 (HHV-8) and preferentially arising in HIV-positive patients has been described and termed as primary effusion lymphoma (PEL). This report describes a case of PEL which has developed in a HIV-negative, 92-year-old man with longstanding Mediterranean Kaposi's sarcoma, a disease also associated with HHV-8 infection. The patient presented with pleural and ascitic effusions in the absence of solid masses within the lungs, mediastinum, thoracic wall or abdominal cavity. The effusions consisted of malignant lymphocytes with morphologic features bridging immunoblastic and anaplastic cells. Immunophenotypic studies revealed that the lymphoma population expressed an antigenic profile consistent with PEL, i.e. the absence of common B- and T-cell markers (non-B, non-T phenotype) coupled to CD138 positivity. Molecular analysis demonstrated infection of the tumor clone by HHV-8 as well as monoclonally rearranged immunoglobulin genes, consistent with a B-cell histogenesis of the lymphoma. In addition, this PEL case harbored PAX-5 gene mutations, which have been recently demonstrated as a key feature of the proto-oncogene hypermutation process involved in the pathogenesis of some lymphoma types. Following two courses of etoposide and prednisone, a partial remission was achieved. The patient died of liver failure 3 months after the diagnosis of PEL. Overall, this case report illustrates the need for an integrated diagnostic approach based on clinical features, morphology, immunophenotype, and molecular genetics to primary lymphomatous effusions.

Abstract
A case of Dirofilariasis by Dirofilaria repens localized in the left temporalis muscle, in a 43-year-old woman, is described. It was acquired in South-western Sicily but became apparent in Pisa. It is the seventh case of human Dirofilariasis reported from this area, confirming the existence of an endemic focus. In spite of the numerous investigations to identify clinically the illness (needle-aspirate, Echography, CTScan) the diagnosis was possible only upon discovery of the nematode in the histological sections of the surgically removed nodule.

Abstract
The Authors report an unusual case of median cleft of the upper lip with pedunculated skin and muscle contracting mass. About one hundred cases of true median cleft lip have been reported, only six showing a median pedunculated mass. As the embryogenesis of this malformation is still not completely clear, we think that any case with this characteristic has to be described. Besides the usual characteristic of the median "hare lip" this case shows a big egg-like pedunculated mass in which muscular tissue has been found well represented, and a wide incomplete maxillary cleft.

Abstract
Following an introductory illustration of the clinical characteristics of the 18q syndrome (De Grouchy syndrome), the paper describes the treatment carried out in a young patient with harelip and cleft palate in addition to chromosomopathy. Although the facial malformation and the karyotype with the deletion of a portion of the long arm of chromosome 18 were diagnosed in utero, the parents, having been correctly informed of the mental retardation usually associated with this syndrome and the possibility of surgical correction of the facial malformation, decided not to abort. The case offers an occasion for analysing the various stages and results obtained to date using a multi-specialised diagnostic approach and functional and surgical treatment of the harelip and cleft palate which have enabled much of the congenital handicap to be corrected.

Abstract
The authors report their experience of the reconstruction by z-plasty in cases of shortness of the lip frenum. Amongst several techniques they used for this correction they got best results utilizing a z-plasty, with wide flaps, planned so that after the transposition of the flaps the medial branch of the z-plasty falls horizontally into the deeper vestibular fornix. In all cases treated by that z-plasty the A. obtained a widening of the adherent part of the gingiva, deepening of the vestibulum, no recurrence of the shortness was observed.

The Authors describe a standardized registration system applied to gnathoplasty and its follow-up. That allows both longitudinal growth study and clinical evaluations on the surgical method. If similar standardized registration systems could be adopted by several clinical teams, a comparison between different gnathoplasty methods should be possible and obviously useful.

Abstract
Ear concha hypertrophy corrected by elliptical conchal excision often resulted in deformity due to lateral deviation of the anterior part of the concha. A modification of the method allows to avoid that deviation: the conchal ellipse is left connected to the conchal floor, is weakened by half thickness incisions parallel to the edge; the conchal floor thus flattened is sutured to the lateral side of the head by non absorbable suture.
