Abstract
AIM To determine whether the duration of respiratory distress symptoms in severe COVID-19 pneumonia affects the need for invasive mechanical ventilation and clinical outcomes. MATERIALS AND METHODS An observational multicentre cohort study of patients hospitalised in five COVID-19-designated ICUs of the University Hospitals of Emilia-Romagna Region. Patients included were adults with pneumonia due to SARS-CoV-2 with PaO₂/FiO₂ ratio <300 mmHg, respiratory distress symptoms, and need for mechanical ventilation (invasive or non-invasive). Exclusion criteria were an uncertain time of respiratory distress, end-of-life decision, and mechanical respiratory support before hospital admission. MEASUREMENTS AND MAIN RESULTS We analysed 171 patients stratified into tertiles according to respiratory distress duration (distress time, DT) before application of mechanical ventilation support. The rate of patients requiring invasive mechanical ventilation was significantly different (p < 0.001) among the tertiles: 17/57 patients in the shortest duration, 29/57 in the intermediate duration, and 40/57 in the longest duration. The respiratory distress time significantly increased the risk of invasive ventilation in the univariate analysis (OR 5.5 [CI 2.48-12.35], p = 0.003). Multivariable regression analysis confirmed this association (OR 10.7 [CI 2.89-39.41], p < 0.001). Clinical outcomes (mortality and hospital stay) did not show significant differences between DT tertiles. DISCUSSION Albeit preliminary and retrospective, our data raised the hypothesis that the duration of respiratory distress symptoms may play a role in COVID-19 patients' need for invasive mechanical ventilation. Furthermore, our observations suggested that specific strategies may be directed towards identifying and managing early symptoms of respiratory distress, regardless of the levels of hypoxemia and the severity of the dyspnoea itself.

Abstract
BACKGROUND Patients with acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) may experience severe acute respiratory failure, even requiring ventilatory assistance. Physiological data on lung mechanics during these events are lacking. METHODS Patients with AE-IPF admitted to Respiratory Intensive Care Unit to receive non-invasive ventilation (NIV) were retrospectively analyzed. Esophageal pressure swing (ΔPes) and respiratory mechanics before and after 2 hours of NIV were collected as primary outcome. The correlation between positive end-expiratory pressure (PEEP) levels and changes of in dynamic compliance (dynCRS) and PaO2/FiO2 ratio was assessed. Further, an exploratory comparison with a historical cohort of ARDS patients matched 1:1 by age, sequential organ failure assessment score, body mass index and PaO2/FiO2 level was performed. RESULTS At baseline, AE-IPF patients presented a high respiratory drive activation with ΔPes = 27 (21-34) cmH2O, respiratory rate (RR) = 34 (30-39) bpm and minute ventilation (VE) = 21 (20-26) L/min. Two hours after NIV application, ΔPes, RR and VE values showed a significant reduction (16 [14-24] cmH2O, p<0.0001, 27 [25-30] bpm, p=0.001, and 18 [17-20] L/min, p=0.003, respectively) while no significant change was found in dynamic transpulmonary pressure, expiratory tidal volume (Vte), dynCRS and dynamic mechanical power. PEEP levels negatively correlated with PaO2/FiO2 ratio and dynCRS (r=-0.67, p=0.03 and r=-0.27, p=0.4, respectively). When compared to AE-IPF, ARDS patients presented lower baseline ΔPes, RR, VE and dynamic mechanical power. Differently from AE-IPF, in ARDS both Vte and dynCRS increased significantly following NIV (p=0.01 and p=0.004 respectively) with PEEP levels directly associated with PaO2/FiO2 ratio and dynCRS (r=0.24, p=0.5 and r=0.65, p=0.04, respectively). CONCLUSIONS In this study, patients with AE-IPF showed a high inspiratory effort, whose intensity was reduced by NIV application without a significant improvement in respiratory mechanics. In an exploratory analysis, AE-IPF patients showed a different mechanical behavior under spontaneous unassisted and assisted breathing compared with ARDS patients of similar severity.

Abstract
Inflammation has been implicated in the pathogenesis of many neurodegenerative diseases. The chemokine IL-8 is thought to have a pathophysiological role in neurodegenerative diseases. IL-8 has recently been shown to induce death of primary cultured motor neurons in vitro. We determined IL-8 levels in the cerebrospinal fluid (CSF) from 38 patients with sporadic amyotrophic lateral sclerosis (ALS) compared to patients with other non-inflammatory neurological diseases (cerebrovascular disease, degenerative dementia, Parkinson's disease, compressive radiculo-myelopathy). Multiple sclerosis (MS) patients were used as positive controls. The levels of IL-8 in the CSF of ALS patients were significantly higher than those of patients with other, non-inflammatory neurological conditions and similar to those of MS patients. The only variable influencing IL-8 in ALS patients was sex, with higher levels in men than in women. The presence of the inflammatory cytokine IL-8 in the CSF of patients with ALS at the time of diagnosis strengthens the hypothesis of a role for this chemokine in neurodegenerative disorders.

Abstract
Clinical cases of coccidioidomycosis are rare in Argentina and are generally found in the large arid precordilleran area of the country. This study aims to perform a retrospective review of all coccidioidomycosis cases documented in the country from 1892 to 2009, and to describe those occurring in the last 4 years. One hundred and twenty eight cases were documented in the 117 year-period. Since the original description of the disease in 1892 until 1939, only 6 cases were registered; between 1940 and 1999, 59 (6-14/10 yrs) and the remaining 63 (49% of total cases) occurred in the last decade. The median age of 34 patients registered in 2006-2009 was 31 years (range: 7-89), male/female ratio was 1.3:1 and 12 patients were immunocompromised. Twenty-six cases were confirmed by direct microscopy and/or culture whereas the remaining ones by serology. All isolates were identified as Coccidioides posadasii. Thirty patients lived in a vast geographic region with epicenter in Catamarca Valley. Between 2006 and 2009, annual disease incidence rates in Catamarca Province increased from historical values below 0.5/100,000 to 2/100,000 inhabitants. Such increase suggests an emergency of coccidioidomycosis in that region.

Abstract
All-trans retinoic acid (RA) induces complete remission in a high proportion of patients with acute promyelocytic leukemia (APL). Nevertheless, most of these patients develop RA resistance and relapse. In an attemp to mimic clinical conditions for the treatment of leukemia, a stably RA-resistant subclone of the human promyelocytic leukemia cell line HL60 (HL60-R) was developed to study the antiproliferative and proapoptotic effect of the retinoid IIF (6-OH-11-O-hydroxyphenantrene) in comparison with RA. Moreover whether the inhibitor of histone deacetylase (HDAC) activity, valproic acid (VPA), could enhance sensitivity to retinoids in HL60-R cells was evaluated. Finally, the effect of IIF on the expression of multidrug resistance-associated protein 1 (MRP1) and P-glycoprotein (P-gp) was evaluated. It was found that IIF strongly suppressed cell proliferation (as measured by growth curves) and induced apoptosis (as measured by DNA fragmentation and Annexin V detection assays), while RA was practically ineffective. The addition of VPA to IIF accentuated the antiproliferative effect of IIF alone and increased apoptosis; the combination of VPA with RA allowed growth arrest. Moreover IIF caused a reduction of transmembrane transporter expression, particularly of P-gp, as shown by Western blotting. Our results suggest that IIF may be useful in controlling the proliferation of RA-resistant leukemia cells, especially in combination with an HDAC inhibitor, such as VPA.

Abstract
The redox state of surface protein thiols influences a variety of cell functions, and we recently reported that adhesion molecules can be redox regulated. We investigated the effect of reducing surface thiols using N-acetylcysteine (NAC) on the biological properties of murine melanoma B16F1 cells. Treating the cells with NAC (5mM for 2h, then removed by washing) augmented their capacity to adhere to fibronectin, as well as to adhere to and invade an endothelial cell monolayer. This was associated with an augmented expression of reduced surface protein thiols. However, when control or NAC-pretreated melanoma cells were injected i.v. in mice to induce experimental lung metastases, we could observe an inhibition of metastatic potential by NAC. This discrepancy suggest that other redox sensitive steps, in addition to adhesion, are important in regulating the metastatic phenotype in vivo.

Abstract
BACKGROUND The complementarity determining region 3 (CDR3) of the immunoglobulin (Ig) heavy chain variable region (VH) is the most reliable molecular fingerprint for most if not all human B cells. The nucleotide sequence encoding for any B-cell tumor-specific VH CDR3 is currently identified by PCR sequencing based on procedures involving the usage of either radioactive materials, patient/family-specific primers, or bacterial cloning. PATIENTS AND METHODS In six consecutive patients with follicular lymphoma we assessed the feasibility of a method that allows for identification of the tumor-specific VH CDR3 using consensus primers while avoiding both radioactive materials and bacterial cloning procedures. RESULTS The tumor-specific VH CDR3 was successfully identified in all six patients in nearly half the time typically required by any other method currently utilized. The feasibility of the proposed method was not significantly affected either by the tumor-specific Ig isotype, or by the tumor infiltration in the original biopsy specimen. In the three patients for whom tumor specimen-derived hybridomas were available, the tumor-specific VH CDR3 was also found in at least 8 of 10 of them. CONCLUSIONS The proposed method allows the ability to quickly identify the B-cell tumor-specific VH CDR3 using consensus primers while avoiding radioactive materials and bacterial cloning procedures.

Abstract
Congenital amegakaryocytic thrombocytopenia (CAMT) without physical anomalies is a rare disease, presenting isolated thrombocytopenia and megakaryocytopenia in infancy, which can evolve into aplastic anemia and leukemia. Recently, two heterozygous truncating mutations of the thrombopoietin (TPO) receptor MPL, coded by the c-mpl gene, were identified in a 10-year-old Japanese patient with CAMT transmitted in an autosomal recessive manner. Here, we report for the first time two different MPL amino-acid substitutions in a 2-year-old Italian boy with CAMT and compound heterozygosis for two (c-mpl point mutations. C-to-T transitions were detected on exons 5 and 12 at the 769 and 1904 cDNA nucleotide positions, respectively. The mutation in exon 5 substitutes an arginine with a cysteine (R257C) in the extracellular domain, 11 amino acids distant from the WSXWS motif conserved in the cytokine-receptor superfamily. The mutation in exon 12 substitutes a proline with a leucine (P635L) in the last amino acid of the C-terminal intracellular domain, responsible for signal transduction. As in the Japanese family, the mutations were both transmitted from the parents. TPO plasma levels were highly increased in the patient. The patient's 7-year-old brother, who was a candidate donor for allografting, turned out to be an asymptomatic heterozygous carrier of P635L and showed defective megakaryocyte colony formation from bone-marrow progenitor cells. The present study provides important confirmation that CAMT can be associated with (c-mpl) mutations.

Abstract
Hereditary thrombocytopenias represent heterogeneous clinical and genetic syndromes. They include a consistent group of families which are considered as a separate clinical entity, characterized by autosomal dominant transmission, incomplete penetrance in females, chronic thrombocytopenia with early age of onset and frequently increased platelet volume, without any other hematologic abnormality. The molecular defect in these families is still unknown. We describe 2 families in 3 generations (10 patients), and report the first study of the TPO/c-mpl system in autosomal dominant thrombocytopenia. We performed mutational screening of c-mpl coding, flanking introns and promoter regions in 2 probands from the two families by DNA sequencing. The results do not provide evidence of c-mpl sequence alterations in either of the 2 families investigated. Moreover, the normal TPO serum levels detected in 5 patients from each family leads us to exclude the possibility of a defect in TPO production in our families. Finally, the involvement of both c-mpl and TPO genes in the pathogenesis of thrombocytopenia in these two families was excluded by negative results of linkage analysis.

Abstract
In vitro hemopoiesis and hemopoietic cytokines production were evaluated in 9 centenarians (median age 100.5 years, age range: 100-104 years), 10 old people (median age: 71 years, age range: 66-73 years), and 10 young people (median age: 35 years, age range: 30-45 years), all carefully selected for their healthy status. The main findings were the following: (i) a trend towards a decreased absolute number of CD34+ progenitor cells in the peripheral blood of old people and centenarians, in comparison to young subjects; (ii) a well-preserved capability of CD34+ cells from old people and centenarians to respond to hemopoietic cytokines, and to form erythroid (BFU-E), granulocyte-macrophagic (CFU-GM), and mixed colonies (CFU-GEMM) in a way (number, size, and morphology) indistinguishable from that of young subjects; (iii) an age-related decreased in vitro production of granulocyte-macrophagic colony-stimulating factor (GM-CSF) and a decreased production of interleukin-3 (IL-3) in centenarians by phytohemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMC); (iv) a linear increase of the serum level of stem cell factor (SCF), measured in the above-mentioned subjects and in 65 additional subjects, including 4 centenarians. These data suggest that basal hematopoietic potential is well preserved in healthy centenarians, and that the hemopoietic cytokine network undergoes a complex remodeling with age.

Abstract
The hematopoietic defect of Diamond-Blackfan anemia (DBA) results in selective failure of erythropoiesis. Thus far, it is not known whether this defect originates from an intrinsic impediment of hematopoietic progenitors to move forward along the erythroid pathway or to the impaired capacity of the bone marrow (BM) microenvironment to support proliferation and differentiation of hematopoietic cells. Reduced longevity of long-term bone marrow cultures, the most physiologic in vitro system to study the interactions of hematopoietic progenitors and hematopoietic microenvironment, is consistent with a defect of an early hematopoietic progenitor in DBA. However, stromal adherent layers from DBA patients generated in a long-term culture system, the in vitro counterpart of BM microenvironment, did not show evidence of any morphologic, phenotypic, or functional abnormality. Our major finding was an impaired capacity of enriched CD34+ BM cell fraction from DBA patients, cultured in the presence of normal BM stromal cells, to proliferate and differentiate along the erythroid pathway. A similar impairment was observed in some DBA patients along the granulomacrophage pathway. Our result points to an intrinsic defect of a hematopoietic progenitor with bilineage potential that is earlier than previously suspected as a relevant pathogenetic mechanism of the disease. The finding of impaired granulopoiesis in some DBA patients underlines the heterogeneity of this rare disorder.

Abstract
Human rhabdomyosarcoma cells produce autocrine and paracrine growth factors that can sustain their growth and malignancy. Here we report constitutive production of stem cell factor (SCF) by 5 of 5 human rhabdomyosarcoma cell lines both of alveolar and embryonal histotype. SCF production, ranging from 30 to 162 pg/ml, was independent from the degree of myogenic differentiation and was not modulated by exogenous addition of retinoic acid (RA) or tumor necrosis factor-alpha (TNF-alpha). Four of 5 rhabdomyosarcoma cell lines expressed the mRNA for SCF receptor c-kit, while the 5th cell line became weakly positive for c-kit mRNA only after stimulation with retinoic acid. On the cell surface, c-kit protein was detectable at very low levels in only 1 of 5 rhabdomyosarcoma cell lines and was not up-regulated by RA or TNF-alpha. Addition of anti-c-kit and anti-SCF blocking antibodies, or of exogenous SCF did not alter the in vitro growth ability of rhabdomyosarcoma cells. In conclusion, our data show that rhabdomyosarcoma cells produce consistent amounts of SCF but did not demonstrate autocrine growth modulation. SCF secretion may thus have a paracrine, rather than an autocrine activity in this tumor.

Abstract
Thrombocytopenia with absent radii (TAR) is a rare autosomal recessive disease characterized by hypomegakaryocytic thrombocytopenia and bilateral radial aplasia. We performed mutational screening of coding and promoter regions of the c-mpl gene, encoding thrombopoietin (TPO) receptor, by sequence analysis in four unrelated patients affected by TAR syndrome. Our results indicate that c-mpl gene mutations are not a common cause of thrombocytopenia in TAR syndrome.

Abstract
In this paper, we describe a novel CF mutation consisting in a C-->T substitution at nucleotide 170 in exon 1 of CFTR gene, converting a serine residue into phenylalanine at position 12 (S13F) of the CFTR protein. This mutation was detected in a single patient of Sardinian descent in compound heterozygosity with T338I, who presented at 9 years of age with hyponatremic dehydration associated with hypochloremia, hypokaliemia and metabolic alkalosis. Sweat chloride values were 120 mmol/l. Now the patient is 11 years old and has not shown so far any pancreatic or lung involvement. The serine to phenylalanine substitution is a non-conservative change, replacing a non polar for a polar amino acid residue and therefore is most likely a disease-causing mutation.

Abstract
A human megakaryocyte cell line (B1647) has been established from bone marrow cells obtained from a patient with acute myelogenous leukaemia (FAB M2). The cells were CD34-, CD33+, HLA-DR+, CD38+, and expressed the immunophenotypic markers of the megakaryocyte lineage (CD41 and von Willebrand factor). Moreover the cells expressed the c-mpl (thrombopoietin receptor) mRNA and protein. On the other hand, the B1647 cells also possessed erythroid lineage characteristics: the vast majority of cells were glycophorin positive, and about 10% of unstimulated cells stained with an anti-globin gamma chain MoAb. In addition, S1 protection analysis demonstrated expression of beta-globin mRNA, and Epo receptor (Epo-R) protein was detected by cytofluorimetric assay. Several growth factors, when tested alone or in combination, failed to influence the B1647 cell growth. A significant increase of cell proliferation was observed only after the addition, in serum-free culture, of recombinant human megakaryocyte growth development factor (MGDF), a recombinant c-mpl ligand encompassing the receptor-binding domain and identical to thrombopoietin (TPO), at concentrations ranging from 0.01 to 1 ng/ml. Interestingly, MGDF failed to induce megakaryocytic differentiation of the B1647 cells, but significantly increased the synthesis of the globin gamma-chain. B1647 cells could be a useful model for studying the biological effect of TPO on common megakaryocyte and erythroid progenitors.

Abstract
Operative hysteroscopy procedures can present complications connected to necessity of kneeping, usually with low viscosity fluids, an uniform distension of uterine cavity. The instilled solutions are reabsorbed through the peritoneum and open uterine venous channels producing a hyperhydration syndrome. The case report shows the rising up of tis syndrome during a hysteroscopy for an uterine myoma resection. The physiopathology includes cardiovascular overload and haemodilution, causing pulmonary, cerebral and tissutal oedema. In this case report the volumes of arterial oxygen saturation and end tidal carbon dioxide obtained on line were the first warning signals. A high CVP value, a plasmatic reduction of Na, albumin, proteins, haemoglobin, haematocrit and osmolarity reflected the excessive fluid reabsorption. For this reason the necessity, during these surgical methods, of considering some practical indications and the absolutely necessary use of clinical and biochemical monitoring systems for these patients.

Abstract
The aim of this study was to test the in vitro cytokine production by peripheral blood mononuclear cells (PBMCs) in patients with Fanconi's anemia (FA). Phytohemagglutinin (PHA)-stimulated PBMCs from 21 patients with FA were studied for their ability to produce interleukin 6 (IL-6), leukemia inhibitory factor (LIF) and granulocyte-macrophage colony stimulating factor (GM-CSF). Enzymatic immunoassay (EIA) was used for both IL-6 and LIF, while GM-CSF was evaluated in a highly sensitive biological assay provided by GM-CSF-dependent M-07e cells. A significant decrease of IL-6 was detected in 9 out of 11 FA patients compared with five normal donors, while similar amounts of LIF were produced from 21 FA patients and 21 healthy subjects. A drastic increase of active GM-CSF was documented in PHA-stimulated PBMC-conditioned medium in all 18 FA patients tested. Since IL-6 and GM-CSF play an important role in maintaining basal hemopoiesis, our results suggest that an abnormal cytokine network may be involved in the pathogenesis of FA pancytopenia.

Abstract
The application of low flow anesthesia goes back already for more than 65 years when Ralph Waters introduced and applied cyclopropane with a very simple canister technique. The guide-lines for the clinical use of the closed circuit anesthesia were published in Chicago and Los Angeles by Professor Lin and Professor Lowe 15 years ago. We examined and followed these procedures on a modern anesthesia machine and easily achieved a good clinical performance. Our results were consistent with the modern anesthesia standard in closed circuit t.i.: economical benefits, environment savage of waste gases, heat production and humidification and last but not least in both techniques a quick anesthesia plane on 10-12 minutes that was consistent with theoretical considerations.
