Delayed neuropsychiatric syndrome after carbon monoxide poisoning: inclusion of hyperbaric oxygen therapy in the recovery protocol

The delayed neuropsychiatric syndrome can arise in the period from 4 days to 5 weeks following carbon monoxide poisoning, and is characterized by neuropsychological deficits, which in some cases become chronic. This case report describes an adult female who apparently suffered self-inflicted carbon monoxide poisoning. She was not treated with hyperbaric oxygen and developed delayed sequelae on day 20. The treatment started with 40 sessions of hyperbaric oxygen therapy and subsequently with neuropsychological rehabilitation and physiotherapy. The treatment resulted in a progressive and almost complete physical and psychological recovery as evidenced by neuropsychometric tests and diagnostic imaging performed in the follow-up. Recovery was attributed to hyperbaric oxygen therapy. Although further research is required, we propose hyperbaric oxygen therapy also in the recovery protocol in the treatment of delayed neuropsychiatric syndrome

Mobilization of healthy donors with plerixafor affects the cellular composition of T-cell receptor (TCR)-αβ/CD19-depleted haploidentical stem cell grafts

Background: HLA-haploidentical hematopoietic stem cell transplantation (HSCT) is suitable for patients lacking related or unrelated HLA-matched donors. Herein, we investigated whether plerixafor (MZ), as an adjunct to G-CSF, facilitated the collection of mega-doses of hematopoietic stem cells (HSC) for TCR-αβ/CD19-depleted haploidentical HSCT, and how this agent affects the cellular graft composition. Methods: Ninety healthy donors were evaluated. Single-dose MZ was given to 30 ‘poor mobilizers’ (PM) failing to attain ≥40 CD34+ HSCs/μL after 4 daily G-CSF doses and/or with predicted apheresis yields ≤12.0x106 CD34+ cells/kg recipient’s body weight. Results: MZ significantly increased CD34+ counts in PM. Naïve/memory T and B cells, as well as natural killer (NK) cells, myeloid/plasmacytoid dendritic cells (DCs), were unchanged compared with baseline. MZ did not further promote the G-CSF-induced mobilization of CD16+ monocytes and the down-regulation of IFN-γ production by T cells. HSC grafts harvested after G-CSF + MZ were enriched in myeloid and plasmacytoid DCs, but contained low numbers of pro-inflammatory 6-sulfo-LacNAc+ (Slan)-DCs. Finally, children transplanted with G-CSF + MZ-mobilized grafts received greater numbers of monocytes, myeloid and plasmacytoid DCs, but lower numbers of NK cells, NK-like T cells and Slan-DCs. Conclusions: MZ facilitates the collection of mega-doses of CD34+ HSCs for haploidentical HSCT, while affecting graft composition

Aperçu sur les origines des organisations des industriels en Lombardie

Il saggio considera alcuni aspetti delle origini e sviluppo delle associazioni imprenditoriali e di categoria a Milano tra il 1860 e il 1914. La ricerca fa riferimento alla documentazione presente nelle pi\uf9 importanti associazioni in Lombardia e intende discutere l\u2019identit\ue0 speciale dell\u2019esperienza milanese e poi lombarda secondo le chiavi interpretative codificate dalla scienza della politica e dalle teorie economiche: sistemi verticali, orizzontali, locali e nazionali. Il saggio analizza, poi, l\u2019evoluzione delle funzioni e illustra come le associazioni lombarde si caratterizzassero per il gran numero di membri e per la capacit\ue0 di garantire servizi sulla base anche di un\u2019armonizzazione dei conflitti di interesse interni. Inoltre si illustra come ci furono importanti differenze fra i fattori che influenzarono l\u2019evoluzione delle associazioni e i progetti dei loro membri. Le condizioni produttive dei differenti settori e la configurazione patrimoniale e imprenditoriale delle imprese plasmarono l\u2019attivit\ue0 funzionale delle associazioni. Inoltre i cosiddetti \u201cselective incentives\u201d sembrano avere un grande importanza nella spiegazione del ruolo economico e sociale delle associazioni imprenditoriali e di categoria e per esempio di particolare rilievo furono le scelte governative in materia di politica doganale e fiscale. Infine, il contributo analizza i metodi di rafforzamento delle associazioni lombarde dalla fine dell\u2019Ottocento in relazione al servizio di supporto allo sviluppo industriale con particolare attenzione a due ambiti che la recente ricerca scientifica in ambito internazionale ha posto in rilievo: il funzionamento dei mercati e le relazioni industriali. La ricerca \ue8 stata condotta con altri studiosi italiani e inserita in un progetto di ricerca tra universit\ue0 europee

selective depletion of αβ t cells and b cells for human leukocyte antigen haploidentical hematopoietic stem cell transplantation a three year follow up of procedure efficiency

Abstract HLA-haploidentical family donors represent a valuable option for children requiring allogeneic hematopoietic stem cell transplantation (HSCT). Because graft-versus-host diseases (GVHD) is a major complication of HLA-haploidentical HSCT because of alloreactive T cells in the graft, different methods have been used for ex vivo T cell depletion. Removal of donor αβ T cells, the subset responsible for GVHD, and of B cells, responsible for post-transplantation lymphoproliferative disorders, have been recently developed for HLA-haploidentical HSCT. This manipulation preserves, in addition to CD34 +  progenitors, natural killer, γδ T, and monocytes/dendritic cells, contributing to anti-leukemia activity and protection against infections. We analyzed depletion efficiency and cell yield in 200 procedures performed in the last 3 years at our center. Donors underwent CD34 + hematopoietic stem cell (HSC) peripheral blood mobilization with granulocyte colony–stimulating factor (G-CSF). Poor CD34 +  cell mobilizers (48 of 189, 25%) received plerixafor in addition to G-CSF. Aphereses containing a median of 52.5 × 10 9 nucleated cells and 494 × 10 6 CD34 +  HSC were manipulated using the CliniMACS device. In comparison to the initial product, αβ T cell depletion produced a median 4.1-log reduction (range, 3.1 to 5.5) and B cell depletion led to a median 3.4-log reduction (range, 2.0 to 4.7). Graft products contained a median of 18.5 × 10 6 CD34 +  HSC/kg recipient body weight, with median values of residual αβ T cells and B cells of 29 × 10 3 /kg and 33 × 10 3 /kg, respectively. Depletion efficiency monitored at 6-month intervals demonstrated steady performance, while improved recovery of CD34 +  cells was observed after the first year ( P  = .0005). These data indicate that αβ T cell and B cell depletion of HSC grafts from HLA-haploidentical donors was efficient and reproducible

Endoscopic endonasal approach for infradiaphragmatic craniopharyngiomas: a multicentric Italian study

Infradiaphragmatic craniopharyngiomas (ICs) represent a distinct subtype, harboring a sellar-suprasellar origin and generally growing in the extra-arachnoidal space contained by the diaphragma sellae. They have been considered ideal for surgical removal through the transsphenoidal approach since the 1960s. The authors present a multicentric national study, intending to selectively analyze IC behavior and the impact of the transsphenoidal endoscopic endonasal approach (EEA) on surgical outcomes

COVID-19 disease-Temporal analyses of complete blood count parameters over course of illness, and relationship to patient demographics and management outcomes in survivors and non-survivors: A longitudinal descriptive cohort study.

BackgroundDetailed temporal analyses of complete (full) blood count (CBC) parameters, their evolution and relationship to patient age, gender, co-morbidities and management outcomes in survivors and non-survivors with COVID-19 disease, could identify prognostic clinical biomarkers.MethodsFrom 29 January 2020 until 28 March 2020, we performed a longitudinal cohort study of COVID-19 inpatients at the Italian National Institute for Infectious Diseases, Rome, Italy. 9 CBC parameters were studied as continuous variables [neutrophils, lymphocytes, monocytes, platelets, mean platelet volume, red blood cell count, haemoglobin concentration, mean red blood cell volume and red blood cell distribution width (RDW %)]. Model-based punctual estimates, as average of all patients' values, and differences between survivors and non-survivors, overall, and by co-morbidities, at specific times after symptoms, with relative 95% CI and P-values, were obtained by marginal prediction and ANOVA- style joint tests. All analyses were carried out by STATA 15 statistical package.Main findings379 COVID-19 patients [273 (72% were male; mean age was 61.67 (SD 15.60)] were enrolled and 1,805 measures per parameter were analysed. Neutrophils' counts were on average significantly higher in non-survivors than in survivors (P60 years (OR = 4.21; 95%CI 1.82-9.77; p = 0.001). Age (OR = 2.59; 95%CI 1.04-6.45; p = 0.042), obesity (OR = 5.13; 95%CI 1.81-14.50; p = 0.002), renal chronic failure (OR = 5.20; 95%CI 1.80-14.97; p = 0.002) and cardiovascular diseases (OR 2.79; 95%CI 1.29-6.03; p = 0.009) were independently associated with poor clinical outcome at 30 days after symptoms' onset.InterpretationIncreased neutrophil counts, reduced lymphocyte counts, increased median platelet volume and anaemia with anisocytosis, are poor prognostic indicators for COVID19, after adjusting for the confounding effect of obesity, chronic renal failure, COPD, cardiovascular diseases and age >60 years

Endoscopic Ultrasound-guided Fine-needle Biopsy With or Without Rapid On-site Evaluation for Diagnosis of Solid Pancreatic Lesions: A Randomized Controlled Non-Inferiority Trial.

The benefit of rapid on-site evaluation (ROSE) on the diagnostic accuracy of endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB) has never been evaluated in a randomized study. This trial aimed to test the hypothesis that in solid pancreatic lesions (SPLs), diagnostic accuracy of EUS-FNB without ROSE was not inferior to that of EUS-FNB with ROSE. A noninferiority study (noninferiority margin, 5%) was conducted at 14 centers in 8 countries. Patients with SPLs requiring tissue sampling were randomly assigned (1:1) to undergo EUS-FNB with or without ROSE using new-generation FNB needles. The touch-imprint cytology technique was used to perform ROSE. The primary endpoint was diagnostic accuracy, and secondary endpoints were safety, tissue core procurement, specimen quality, and sampling procedural time. Eight hundred patients were randomized over an 18-month period, and 771 were analyzed (385 with ROSE and 386 without). Comparable diagnostic accuracies were obtained in both arms (96.4% with ROSE and 97.4% without ROSE, P = .396). Noninferiority of EUS-FNB without ROSE was confirmed with an absolute risk difference of 1.0% (1-sided 90% confidence interval, -1.1% to 3.1%; noninferiority P < .001). Safety and sample quality of histologic specimens were similar in both groups. A significantly higher tissue core rate was obtained by EUS-FNB without ROSE (70.7% vs. 78.0%, P = .021), with a significantly shorter mean sampling procedural time (17.9 ± 8.8 vs 11.7 ± 6.0 minutes, P < .0001). EUS-FNB demonstrated high diagnostic accuracy in evaluating SPLs independently on execution of ROSE. When new-generation FNB needles are used, ROSE should not be routinely recommended.
