RESUMEN

With the spread of the pandemic and the introduction of measures aimed at its containment, it is necessary to understand in specific national contexts how home quarantine has affected the psychophysical well-being of academics, and their ability to maintain integrity. To this end we constructed an online questionnaire to investigate the levels of stress, well-being, and work-life balance in relationship with living and working conditions. Moreover, the questionnaire was designed to obtain information about the perceived occurrence, increase or decrease of misconduct in research (e.g., research misconduct by colleagues) and professional relationships (e.g., misbehaviors between colleagues, from students and toward students). The questionnaire was administered online by contacting faculty at three universities in Tuscany, Italy, asking them to relate their experience during the first lockdown (March-May 2020). Faculty members were invited to complete the questionnaire by their institutional e-mail account. The final sample consisted of 581 respondents. The results showed that inadequacies of the equipment, and particularly poor internet connection, were significantly correlated with main issues reported, such as relationships with students and research activities. Female teachers primarily suffered from stressful conditions, lacked well-being, and experienced work-life imbalance. Stress levels were related to perceptions of the frequency of misconduct and of an increase in their frequency during the period of home quarantine. Female professors, when compared to their male counterparts, perceived misconduct from students as increased and more frequent in the period of quarantine. Results point to a gender issue that is likely to arise from conditions of domestic activities imbalance and that increases stress and misconduct perception.

RESUMEN

This paper presents an experiment in which participants had to discriminate three mid-air haptic shapes (circle, square, point) by reporting whether the haptic stimulus (e.g. circle on the palm of the hand) was compatible with an image (e.g. a circle) or a word (e.g. 'circle') displayed on a screen. Results indicate that only the 'point' stimulus was appreciably recognised and discriminated in terms of accuracy and time needed for the identification. Accuracy increased with repetition, and response time decreased, suggesting a learning effect. The comparison between visual and textual labels shows that for the haptic point stimulus there is no significant difference but a tendency to have greater accuracy with images than with texts, while the opposite result is found for the circle stimulus. This outcome suggests the need for new experiments focussed of the effect of visual/textual labels to make the recognition/discrimination tasks of haptic stimuli easier. Practitioner Summary: Three haptic shapes were presented with images or texts, matching or not the stimuli. The point was easy to recognise, while the circle and the square were difficult to discriminate against each other. Visual/textual labels bring contradictory results for different shapes.

RESUMEN

The relationship between stress and unethical behaviour amongst non-tenured research staff in academia is a relatively unexplored phenomenon. The research reported herein was therefore carried out with the aim of exploring the relationship(s) between stress, the socio-organisational factors which contribute to it, job satisfaction, perceptions of job instability, and the occurrence of unethical behaviour in research. 793 Italian researchers participated in the research-all of whom were working on fixed-term contracts-after being individually requested to complete an online questionnaire. The data indicate that unethical behaviours occur with alarming frequency. The stress level reported is quite high, as is the level of perceived job insecurity, both of which impact upon levels of job satisfaction. Perceived stress levels also seem to play a role in the commission of unethical behaviours, but this relationship is irrelevant when one considers the role of social and organisational factors that are known to induce it. Indeed, it seems that there are various socio-organisational determinants of stress that have an obvious direct negative influence on the commission of unethical behaviours more than the stress level per se. This research paints a worrying picture in relation to the psycho-physical state of non-tenured researchers as a result of the working conditions in which they find themselves in Italian universities.

RESUMEN

BACKGROUND: Chronic graft-versus-host disease (GVHD) is the leading cause of later illness and death after allogeneic hematopoietic stem-cell transplantation. We hypothesized that the inclusion of antihuman T-lymphocyte immune globulin (ATG) in a myeloablative conditioning regimen for patients with acute leukemia would result in a significant reduction in chronic GVHD 2 years after allogeneic peripheral-blood stem-cell transplantation from an HLA-identical sibling. METHODS: We conducted a prospective, multicenter, open-label, randomized phase 3 study of ATG as part of a conditioning regimen. A total of 168 patients were enrolled at 27 centers. Patients were randomly assigned in a 1:1 ratio to receive ATG or not receive ATG, with stratification according to center and risk of disease. RESULTS: After a median follow-up of 24 months, the cumulative incidence of chronic GVHD was 32.2% (95% confidence interval [CI], 22.1 to 46.7) in the ATG group and 68.7% (95% CI, 58.4 to 80.7) in the non-ATG group (P<0.001). The rate of 2-year relapse-free survival was similar in the ATG group and the non-ATG group (59.4% [95% CI, 47.8 to 69.2] and 64.6% [95% CI, 50.9 to 75.3], respectively; P=0.21), as was the rate of overall survival (74.1% [95% CI, 62.7 to 82.5] and 77.9% [95% CI, 66.1 to 86.1], respectively; P=0.46). There were no significant between-group differences in the rates of relapse, infectious complications, acute GVHD, or adverse events. The rate of a composite end point of chronic GVHD-free and relapse-free survival at 2 years was significantly higher in the ATG group than in the non-ATG group (36.6% vs. 16.8%, P=0.005). CONCLUSIONS: The inclusion of ATG resulted in a significantly lower rate of chronic GVHD after allogeneic transplantation than the rate without ATG. The survival rate was similar in the two groups, but the rate of a composite end point of chronic GVHD-free survival and relapse-free survival was higher with ATG.

RESUMEN

BACKGROUND: Gram-negative bacteremia (GNB) is a major cause of illness and death after hematopoietic stem cell transplantation (HSCT), and updated epidemiological investigation is advisable. METHODS: We prospectively evaluated the epidemiology of pre-engraftment GNB in 1118 allogeneic HSCTs (allo-HSCTs) and 1625 autologous HSCTs (auto-HSCTs) among 54 transplant centers during 2014 (SIGNB-GITMO-AMCLI study). Using logistic regression methods. we identified risk factors for GNB and evaluated the impact of GNB on the 4-month overall-survival after transplant. RESULTS: The cumulative incidence of pre-engraftment GNB was 17.3% in allo-HSCT and 9% in auto-HSCT. Escherichia coli, Klebsiella pneumoniae, and Pseudomonas aeruginosa were the most common isolates. By multivariate analysis, variables associated with GNB were a diagnosis of acute leukemia, a transplant from a HLA-mismatched donor and from cord blood, older age, and duration of severe neutropenia in allo-HSCT, and a diagnosis of lymphoma, older age, and no antibacterial prophylaxis in auto-HSCT. A pretransplant infection by a resistant pathogen was significantly associated with an increased risk of posttransplant infection by the same microorganism in allo-HSCT. Colonization by resistant gram-negative bacteria was significantly associated with an increased rate of infection by the same pathogen in both transplant procedures. GNB was independently associated with increased mortality at 4 months both in allo-HSCT (hazard ratio, 2.13; 95% confidence interval, 1.45-3.13; P <.001) and auto-HSCT (2.43; 1.22-4.84; P = .01). CONCLUSIONS: Pre-engraftment GNB is an independent factor associated with increased mortality rate at 4 months after auto-HSCT and allo-HSCT. Previous infectious history and colonization monitoring represent major indicators of GNB. CLINICAL TRIALS REGISTRATION: NCT02088840.

RESUMEN

Approximately one-third of patients with myelodysplastic syndrome (MDS) receiving allogeneic hematopoietic stem cell transplantation (HSCT) are cured by this treatment. Treatment failure may be due to transplant complications or relapse. To identify predictive factors for transplantation outcome, we studied 519 patients with MDS or oligoblastic acute myeloid leukemia (AML, <30% marrow blasts) who received an allogeneic HSCT and were reported to the Gruppo Italiano Trapianto di Midollo Osseo registry between 2000 and 2011. Univariate and multivariate survival analyses were performed using Cox proportional hazards regression. High-risk category, as defined by the revised International Prognostic Scoring System (IPSS-R), and monosomal karyotype were independently associated with relapse and lower overall survival after transplantation. On the other hand, older recipient age and high hematopoietic cell transplantation-comorbidity index (HCT-CI) were independent predictors of nonrelapse mortality. Accounting for various combinations of patient's age, IPSS-R category, monosomal karyotype, and HCT-CI, the 5-year probability of survival after allogeneic HSCT ranged from 0% to 94%. This study indicates that IPSS-R risk category and monosomal karyotype are important factors predicting transplantation failure both in MDS and oligoblastic AML. In addition, it reinforces the concept that allogeneic HSCT offers optimal eradication of myelodysplastic hematopoiesis when the procedure is performed before MDS patients progress to advanced disease stages.

RESUMEN

We report the outcome of 30 consecutive patients with Hodgkin disease (HD) who underwent single-unit UCBT. Most (90%) patients had failed previous autologous hematopoietic stem cell transplantation. The conditioning regimens were based on combinations of thiotepa, busulfan, cyclophosphamide or fludarabine, and antithymocyte globulin. The cumulative incidence (CI) of myeloid engraftment was 90% [95% confidence interval (C.I.), 74-98%] with a median of 18 d (range, 10-48). CI of acute graft-versus-host disease (GvHD) grades II-IV was 30% (95% C.I., 17-44%), while the incidence of chronic GVHD was 42% (95% C.I., 23-77%). The non-relapse mortality (NRM) at 100 d and 4 yr was 30% (95% C.I., 13-46%) and 47% (95% C.I., 29-65%), respectively. EBV-related post-transplant lymphoproliferative disease (EBV-PTLD) accounted for more than one-third of transplant-related death, with an estimate incidence of 26% (95% C.I., 9-44). The incidence of relapse at 4 yr was 25% (95% C.I., 9-42%). Four-year event-free survival (EFS) and overall survival (OS) were 28% and 30%, respectively. Despite a high NRM and an unexpected high incidence of EBV-PTLD, UCBT in heavily pretreated HD patients is an option for patients lacking a suitable adult donor, provided the disease is not in refractory relapse.

RESUMEN

BACKGROUND: The standard busulfan-cyclophosphamide myeloablative conditioning regimen is associated with substantial non-relapse mortality in patients older than 40 years with acute myeloid leukaemia who are undergoing allogeneic stem-cell transplantation. Because the combination of busulfan plus fludarabine has been proposed to reduce non-relapse mortality, we aimed to compare this treatment with busulfan plus cyclophosphamide as a preparative regimen in these patients. METHODS: We did an open-label, multicentre, randomised, phase 3 trial for patients with acute myeloid leukaemia at 25 hospital transplant centres in Italy and one in Israel. Eligible patients were aged 40-65 years, had an Eastern Cooperative Oncology Group performance status less than 3, and were in complete remission. Patients were randomly assigned 1:1 to receive intravenous busulfan plus cyclophosphamide or busulfan plus fludarabine. Treatment allocations were not masked to investigators or patients. Randomisation was done centrally via a dedicated web-based system using remote data entry, with patients stratified by donor type and complete remission status. Patients allocated to busulfan plus cyclophosphamide received intravenous busulfan 0·8 mg/kg four times per day during 2 h infusions for four consecutive days (16 doses from days -9 through -6; total dose 12·8 mg/kg) and cyclophosphamide at 60 mg/kg per day for two consecutive days (on days -4 and -3; total dose 120 mg/kg). Patients allocated to busulfan plus fludarabine received the same dose of intravenous busulfan (from days -6 through -3) and fludarabine at 40 mg/m(2) per day for four consecutive days (from days -6 through -3; total dose 160 mg/m(2)). The primary endpoint was 1-year non-relapse mortality, which was assessed on an intention-to-treat basis; safety outcomes were assessed in the per-protocol population. This trial has been completed and is registered with ClinicalTrials.gov, number NCT01191957. FINDINGS: Between Jan 3, 2008, and Dec 20, 2012, we enrolled and randomly assigned 252 patients to receive busulfan plus cyclophosphamide (n=125) or busulfan plus fludarabine (n=127). Median follow-up was 27·5 months (IQR 9·8-44·3). 1-year non-relapse mortality was 17·2% (95% CI 11·6-25·4) in the busulfan plus cyclophosphamide group and 7·9% (4·3-14·3) in the busulfan plus fludarabine group (Gray's test p=0·026). The most frequently reported grade 3 or higher adverse events were gastrointestinal events (28 [23%] of 121 patients in the busulfan plus cyclophosphamide group and 26 [21%] of 124 patients in the busulfan plus fludarabine group) and infections (21 [17%] patients in the busulfan plus cyclophosphamide group and 13 [10%] patients in the busulfan plus fludarabine group had at least one such event). INTERPRETATION: In older patients with acute myeloid leukaemia, the myeloablative busulfan plus fludarabine conditioning regimen is associated with lower transplant-related mortality than busulfan plus cyclophosphamide, but retains potent antileukaemic activity. Accordingly, this regimen should be regarded as standard of care during the planning of allogeneic transplants for such patients. FUNDING: Agenzia Italiana del Farmaco.

RESUMEN

BACKGROUND: An in-depth assessment of work-related stress was conducted in a major national telecommunications company undergoing major changes. The assessment was made on three homogeneous groups of workers and covered a large representative sample of the corresponding populations. OBJECTIVES: To identify the main sources of stress for the three populations of workers, stimulate a discussion on the possible corrective actions, and assess the impact of the on-going organizational changes on workers' health. METHODS: The assessment started with an analysis of the objective stress indicators listed in the INAIL (National Insurance Institute for Occupational Diseases and Accidents) Checklist. This was followed by a combination of qualitative and quantitative investigations on work context and tasks and on the subjective perceptions of workers, which were carried out by using: semi-structured interviews with management, field observations of work tasks, focus groups and questionnaires (GHQ-12, HSE Indicator Tool, ad-hoc questionnaire). RESULTS: The assessment allowed identification of the critical areas to be addressed with specific interventions: relationship with the company, work performance, work organization, and equipment. CONCLUSIONS: the investigation allowed to identification of specific practical actions (improvement of technological tools; professional development through training courses) as well as strategic actions ( re-establish relationship of trust with the company) so as to mitigate the workers' level of stress. Analysis of the results also showed that the three targeted populations differed in the degree of acceptance and understanding of the organizational changes.

RESUMEN

Epidemiologic investigation of invasive fungal diseases (IFDs) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) may be useful to identify subpopulations who might benefit from targeted treatment strategies. The Gruppo Italiano Trapianto Midollo Osseo (GITMO) prospectively registered data on 1858 consecutive patients undergoing allo-HSCT between 2008 and 2010. Logistic regression analysis was performed to identify risk factors for proven/probable IFD (PP-IFD) during the early (days 0 to 40), late (days 41 to 100), and very late (days 101 to 365) phases after allo-HSCT and to evaluate the impact of PP-IFDs on 1-year overall survival. The cumulative incidence of PP-IFDs was 5.1% at 40 days, 6.7% at 100 days, and 8.8% at 12 months post-transplantation. Multivariate analysis identified the following variables as associated with PP-IFDs: transplant from an unrelated volunteer donor or cord blood, active acute leukemia at the time of transplantation, and an IFD before transplantation in the early phase; transplant from an unrelated volunteer donor or cord blood and grade II-IV acute graft-versus-host disease (GVHD) in the late phase; and grade II-IV acute GVHD and extensive chronic GVHD in the very late phase. The risk for PP-IFD was significantly higher when acute GVHD was followed by chronic GVHD and when acute GVHD occurred in patients undergoing transplantation with grafts from other than matched related donors. The presence of PP-IFD was an independent factor in long-term survival (hazard ratio, 2.90; 95% confidence interval, 2.32 to 3.62; P < .0001). Our findings indicate that tailored prevention strategies may be useful in subpopulations at differing levels of risk for PP-IFDs.

RESUMEN

To evaluate trends in allografting from unrelated donors, we conducted a study on 196 consecutive myeloma patients transplanted between 2000 and 2009 in Italy. Twenty-eight percent, 37%, and 35%, respectively, received myeloablative, reduced-intensity, and nonmyeloablative conditioning. In these 3 cohorts, 1-year and 5-year transplantation-related mortalities were 28.8% and 37.0%, 20.3% and 31.3%, and 25.0% and 30.3%, respectively (P = .745). Median overall survival (OS) and event-free survival from transplantation for the 3 cohorts were 29 and 10 months, 11 and 6 months, and 32 and 13 months, respectively (P = .039 and P = .049). Overall cumulative incidences of acute and chronic graft-versus-host-disease (GVHD) were 46.1% and 51.1%. By Cox multivariate analyses, chronic GVHD was significantly associated with longer OS (hazard ratio [HR], .51; P = .009), whereas the use of peripheral blood stem cells was borderline significant (HR, .55; P = .051). Better response posttransplantation was associated with longer event-free survival (HR, 2.13 to 4.25; P < .001). Acute GVHD was associated with poorer OS (HR, 2.53; P = .001). This analysis showed a strong association of acute and chronic GVHD and depth of response posttransplantation with clinical outcomes. Long-term disease control remains challenging regardless of the conditioning. In the light of these results, prospective trials may be designed to better define the role of allografting from unrelated donors in myeloma.

RESUMEN

Allogeneic hematopoietic stem cell transplantation (HSCT) represents the only curative treatment for patients with myelodysplastic syndrome (MDS), but involves non-negligible morbidity and mortality. Registry studies have shown that advanced disease stage at transplantation is associated with inferior overall survival. To define the optimal timing of allogeneic HSCT, we carried out a decision analysis by studying 660 patients who received best supportive care and 449 subjects who underwent transplantation. Risk assessment was based on both the International Prognostic Scoring System (IPSS) and the World Health Organization classification-based Prognostic Scoring System (WPSS). We used a continuous-time multistate Markov model to describe the natural history of disease and evaluate the effect of allogeneic HSCT on survival. This model estimated life expectancy from diagnosis according to treatment policy at different risk stages. Relative to supportive care, estimated life expectancy increased when transplantation was delayed from the initial stages until progression to intermediate-1 IPSS-risk or to intermediate WPSS-risk stage, and then decreased for higher risks. Modeling decision analysis on WPSS versus IPSS allowed better estimation of the optimal timing of transplantation. These observations indicate that allogeneic HSCT offers optimal survival benefits when the procedure is performed before MDS patients progress to advanced disease stages.

RESUMEN

Hodgkin lymphoma relapsing after autologous transplantation (autoSCT) has a dismal outcome. Allogeneic transplantation (alloSCT) using reduced intensity conditioning (RIC) is a salvage option, but its effectiveness is still unclear. To evaluate the role of RIC alloSCT, we designed a retrospective study based on the commitment of attending physicians to perform a salvage alloSCT; thus, only Hodgkin lymphoma patients having human leukocyte antigen-typing immediately after the failed autoSCT were included. Of 185 patients, 122 found an identical sibling (55%), a matched unrelated (32%) or a haploidentical sibling (13%) donor; 63 patients did not find any donor. Clinical features of both groups did not differ. Two-year progression-free (PFS) and overall survival (OS) were better in the donor group (39.3% vs 14.2%, and 66% vs 42%, respectively, P < .001) with a median follow-up of 48 months. In multivariable analysis, having a donor was significant for better PFS and OS (P < .001). Patients allografted in complete remission showed a better PFS and OS. This is the largest study comparing RIC alloSCT versus conventional treatment after a failed autoSCT, indicating a survival benefit for patients having a donor.

RESUMEN

Patients who relapse after an autologous hematopoietic stem cell transplantation (SCT) have a very poor prognosis. We have retrospectively analyzed diffuse large B cell lymphoma patients who underwent an allo-SCT after an auto-SCT relapse reported in the Gruppo Italiano Trapianto di Midollo Osseo (GITMO) database. From 1995 to 2008, 3449 autologous transplants were reported in the GITMO database. Eight hundred eighty-four patients relapsed or progressed after transplant; 165 patients, 19% of the relapsed patients, were treated with allo-transplant. The stem cell donor was related to the patient in 108 cases. A reduced intensity conditioning regimen was used in 116. After allo-SCT, 72 patients (43%) obtained a complete response and 9 obtained a partial response with an overall response rate of 49%; 84 patients (51%) experienced rapid progression of disease. Ninety-one patients died, 45 due to disease and 46 due to treatment-related mortality. Acute graft-versus-host disease was recorded in 57 patients and a chronic GvHD in 38 patients. With a median follow-up of 24 months (2-144) after allo, overall survival (OS) was 39%, and after a median of 21 months (2-138) after allo, progression-free survival (PFS) was 32%. Multivariate analysis indicated that the only factors affecting OS were status at allo-SCT, and those affecting PFS were status at allo-SCT and stem cell donor. This retrospective analysis shows that about one-fifth of patients with diffuse large B cell lymphoma who experience relapse after autologous transplantation may be treated with allogeneic transplantation. Moreover, the only parameter affecting either OS or PFS was the response status at the time of allo-SCT.

RESUMEN

Toxoplasma gondii is an opportunistic parasite, which very unusually may cause acute encephalitis in patients undergoing chemotherapy or hematopoietic stem cell transplant. The prognosis is usually dismal also because of late diagnosis, depending on the limited availability of specific diagnostic tools. An early diagnosis allows effective intervention with specific antibiotics, which may provide a chance for cure. We report 2 cases of cerebral toxoplasmosis in which the use of polymerase chain reaction on cerebrospinal fluid allowed a prompt diagnosis and specific therapy, which was followed by clinical response and negativization at follow-up studies of T. gondii genome on cerebrospinal fluid by polymerase chain reaction and by brain imaging.

RESUMEN

Research has usually considered cyberbullying as a unitary phenomenon. Thus, it has been neglected to explore whether the specific online aggressive behaviours relate differentially to demographic features of the perpetrators of online aggressive actions, their personality characteristics, or to the ways in which they interact with the Internet. To bridge this gap, a study was conducted through a questionnaire administered online to 1228 Italian high-school students (Female: 61.1%; 14-15 yo: 48.%; 16-17 yo: 29.1%; 18-20 yo: 20.4%, 21-25 yo: 1.6%; Northern Italy: 4.1%; Central Italy: 59.2%; Southern Italy: 36.4%). The questionnaire, in addition to items about the use of social media, mechanisms of Moral Disengagement and personality characteristics of the participants in the study, also included a scale for the measurement of cyberbullying through the reference to six aggressive behaviours. The results indicate that cyberbullying can be considered as a non-unitary phenomenon in which the different aggressive behaviours can be related to different individual characteristics such as gender, personality traits and the different ways of interacting with social media. Moreover, the existence of two components of cyberbullying has been highlighted, one related to virtual offensive actions directly aimed at a victim, the other to indirect actions, more likely conducted involving bystanders. These findings open important perspectives for understanding, preventing, and mitigating cyberbullying among adolescents.

RESUMEN

Asthma is an ever-increasing disease with a highly variable prevalence among different ethnic groups. Information on hospital admission for acute exacerbation of asthma in adult patients and data regarding short-term prognosis of these patients are limited. We, thus, performed an epidemiological study on hospital admission for asthma acute exacerbation in Italy using hospital discharge database records derived from all Italian hospitals. Patients > 15 years old were identified using clinical Modification (ICD-9-CM) codes. Information on baseline characteristics, vital status at discharge, duration of hospitalization, and up to five secondary discharge diagnoses was collected. Comorbidity was evaluated using the Charlson comorbidity index (CCI). During the observation period (2013-2014), 20,056 patients with asthma acute exacerbation were hospitalized. Median length of hospitalization was 7.9 days (interquartile range 4-10) and mean in-hospital mortality was 0.8%. In-hospital mortality and length of hospitalization varied among different regions (from 0 to 2.9% and from 6.5 to 8.9 days, respectively). Old age, invasive and non-invasive mechanical ventilation, and CCI resulted as significantly associated with higher in-hospital mortality. Our study results, on a large sample of patients, confirm that hospitalization for asthma acute exacerbation is not uncommon among Italian current population. Older age, high CCI, and use of ventilator support were associated with a higher mortality rate. These findings should be analyzed to set up appropriate health care policies on patients with asthma.

RESUMEN

Background: Multi-drug resistant organisms (MDRO) are an emerging health problem with an important impact on clinical outcome in Intensive Care Units (ICUs) and immunocompromised patients. Conversely, the role of MDRO colonization in Internal Medicine is less clear. The objective of our study is to evaluate the clinical impact (namely sepsis development, in-hospital and 30-days mortality, and re-hospitalization) of MDRO colonization in Internal Medicine. Methods: Patients admitted to our Internal Medicine Unit between January 2019 and March 2020 were potentially includible. Outcomes in patients with a positive rectal swab for MDRO (RS+) and in patients without a RS+ were compared. Results of the multivariate analyses were expressed as Odds Ratios (ORs) and the corresponding 95% Confidence Interval (CI). Results: In a cohort of 2147 patients, 77 patients with RS+ were consecutively identified; 377 patients with a rectal swab negative for MDRO were randomly selected from the same cohort (five for each patient with RS+). At the multivariate analysis, RS+ was associated with an increased risk of sepsis development during hospitalization (OR 4.18; 95% CI, 1.99-8.78) and with death or re-hospitalization at 30 days (OR 4.79; 95% CI, 2.79-8.23), whereas RS+ did not appear to be associated with death during hospitalization or need for ICU transfer. Conclusions: Our results suggest for the first time a prognostic role for RS+ in Internal Medicine. Thus, assessment of rectal swab at hospital admission appears useful even in this setting. However, larger prospective studies and a cost-benefit analysis are needed to confirm our preliminary findings.

RESUMEN

BACKGROUND: In COVID-19 patients the progressive clinical deterioration seems secondary to the activation of a cytokine storm. Ferritin is considered a direct mediator of the immune system and some evidences suggested a shared physio-pathogenic basis between COVID-19 and 'Hyperferritinemic Syndromes.' The aim of our study was to evaluate the prognostic role of ferritin in COVID-19 patients. METHODS: We retrospectively studied consecutive COVID-19 patients admitted to four Italian Internal Medicine Units. Role of potential prognostic markers was evaluated with binary logistic regression analysis and results were expressed as odds ratios (ORs) with the corresponding 95% confidence intervals (CIs). Poor outcome was defined as death or need to transfer in the intensive care unit. RESULTS: Two hundred patients were included (mean age 68.75 ± 13.22 years). Ferritin value was highly elevated (>3000 ng/mL) in 8% of our population; 13% of patients were transferred to intensive care units and 12% of patients died. At multivariate analysis, highly elevated ferritin levels (OR 16.67 C.I. 4.89-57.57 p < 0.001) and hemoglobin < 10 g/dL (OR 8.88 C.I. 2.02-39.09 p = 0.004) were independently associated with a bad outcome.Patients with ferritin values > 3000 ng/ml appeared to have an inflammatory activation with elevated values of CRP and D-dimer and low values of lymphocyte count. CONCLUSION: Our results confirm the prognostic role of ferritin in hospitalized COVID-19 patients. Patients with high ferritin levels should be considered critically ill and treated in an adequate setting. Furthermore, COVID-19 seems to share some characteristics with hyperferritinemic syndromes with potential therapeutic implications.

RESUMEN

BACKGROUND: Mesenchymal stem cells can differentiate into endothelial cells and participate in angiogenesis in adults. In experimental models of acute myocardial infarction, mesenchymal stem cells led to the recovery of cardiac function through the formation of a new vascular network. OBJECTIVE: To describe treatment with intravenous infusions of expanded autologous mesenchymal stem cells in 1 patient with critical limb ischemia due to systemic sclerosis. DESIGN: Case report. SETTING: The rheumatology unit at the University of Florence, Florence, Italy. PATIENT: A woman, aged 34 years, with systemic sclerosis who developed acute gangrene of the upper and lower limbs. INTERVENTION: 3 intravenous pulses of expanded autologous mesenchymal stem cells. MEASUREMENTS: Angiography, skin histopathology, and immunohistochemistry. RESULTS: Areas of necrotic skin were reduced after the first mesenchymal stem-cell infusion. After the third infusion, angiography showed revascularization of the patient's extremities. Skin section analysis revealed cell clusters with tubelike structures, and angiogenic factors were strongly expressed. LIMITATION: Causality cannot be established by a single case. CONCLUSION: In patients with systemic sclerosis who have severe peripheral ischemia, intravenous infusion of expanded autologous mesenchymal stem cells may foster the recovery of the vascular network, restore blood flow, and reduce skin necrosis.
