SurvIAE: Survival prediction with Interpretable Autoencoders from Diffuse Large B-Cells Lymphoma gene expression data.

Background: In Diffuse Large B-Cell Lymphoma (DLBCL), several methodologies are emerging to derive novel biomarkers to be incorporated in the risk assessment. We realized a pipeline that relies on autoencoders (AE) and Explainable Artificial Intelligence (XAI) to stratify prognosis and derive a gene-based signature.

Methods: AE was exploited to learn an unsupervised representation of the gene expression (GE) from three publicly available datasets, each with its own technology.

Reversal of MYB-dependent suppression of MAFB expression overrides leukaemia phenotype in MLL-rearranged AML.

The transcription factor MYB plays a pivotal role in haematopoietic homoeostasis and its aberrant expression is involved in the genesis and maintenance of acute myeloid leukaemia (AML). We have previously demonstrated that not all AML subtypes display the same dependency on MYB expression and that such variability is dictated by the nature of the driver mutation. However, whether this difference in MYB dependency is a general trend in AML remains to be further elucidated.

Alteration of Na/H exchange regulatory factor-1 protein levels in anogenital lesions positive for mucosal high-risk human papillomavirus type 16.

Mucosal high-risk (HR) human papillomaviruses (HPV) are associated with anogenital carcinogenesis. The products of two early genes, E6 and E7, act as major viral oncoproteins. Functional studies in experimental models showed that HPV16 E6 induces degradation of the PDZ protein, the Na+/H+ exchanger regulatory factor-1 (NHERF-1).

The value of lung ultrasound monitoring in H1N1 acute respiratory distress syndrome.

We present the case of a healthy young male who developed acute respiratory failure as a result of infection with influenza A/H1N1 of swine-origin and in whom ventilatory support was optimised and recovery of lung function was monitored by the use of sequential chest ultrasound examinations. The potential pivotal role of bedside lung ultrasonography in H1N1-induced respiratory failure is discussed.

Validation of the Clinical COPD questionnaire in Italian language.

Background: The development and validation study of the Clinical Chronic Obstructive Disease (COPD) Questionnaire (CCQ) has recently been published in this journal. The CCQ is the first questionnaire that incorporates both clinician and patient guideline goals in the clinical control evaluation of patients with COPD in general clinical practice. The aim of this study is the validation of the CCQ questionnaire in Italian, in specific pulmonary disease clinical practice.

[Complete neurologic recovery after prolonged cardiac arrest caused by refractory ventricular fibrillation. Clinical case].

The clinical case of a 45-year-old patient referred to us for chest pain and with clinical examination and ECG negative for ischaemic damage, is reported. The patient, hospitalised in a bed without an ECG monitor, presented heart failure due to ventricular fibrillation. He was re-examined first with ventilation and EMC and then with defibrillation.

Operational problems of an iron supplementation programme for pregnant women: an assessment of UNRWA experience.

Assessed is a large-scale iron supplementation programme for the 70 000 pregnant refugee women cared for by the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA). For this purpose, a retrospective survey of 1267 antenatal records was conducted in health centres located in the West Bank, Gaza, Syrian Arab Republic, Jordan, and Lebanon. The following operational problems were identified: late entry to antenatal care; high drop-out rate from antenatal care; low compliance in follow-up haemoglobin examinations; and misdirected continued testing of women who were not anaemic at registration.

[Unilateral pulmonary edema caused by heart failure. Report of 2 clinical cases].

The authors present two case reports of cardiogenic unilateral pulmonary edema. The information provided by hemodynamic monitoring have not been essential for diagnosis which was bases on clinical, radiological and echocardiographic findings and confirmed by the clinical response to a specific treatment. The authors briefly review the mechanisms which may cause the atypical distribution of the cardiogenic pulmonary edema.

[Propofol-midazolam in continuous infusion for sedation in intensive care].

Two groups of 11 ICU respiratory patients ventilated with PSV have been sedated with propofol (group I) or with midazolam (group II). After the endovenous administration of the induction dose (propofol 1.5 mg/kg; midazolam 0.

[Gastric tonometry. Experience of a polyvalent intensive care unit].

Tonomitor NG tube was positioned in the stomach of 11 critical ill patients during their stay in ICU and 48 measurements of intramucosal pH (pHi) have been performed. In 7 patients haemodynamic measurement were performed in concomitance with each pHi measure. The Authors looked for statistical relations between pHi and SAPS, pHa, HCO3-a, MAP, DO2/BSA, VO2/BSA, SvO2, diuresis and outcome.

[Usefulness of monitoring the mixed venous blood saturation (SvO2) in the diagnosis of heart rupture. A clinical case].

We describe a case report of acute left ventricular free wall rupture during acute myocardial infarction in a sedated and curarised patient. Continuous monitoring of SvO2 was very useful on early diagnosis.

[The use of Opticath in the correct measurement of the pulmonary capillary wedge pressure].

The Authors assess the utility of the on-line monitoring of SvO2 during 156 measurements of pulmonary capillary wedge pressure (PCWP) done on 52 Intensive Care Unit patients. The measurement was always right when the SvO2 increased more than 90%. The Authors found a good correlation between the SvO2 monitored during the measurement of the PCWP and the saturation of pulmonary capillary blood measured by cooximeter.

[Tetanus disease. Experience with 2 intensive treatments during 13 years].

The Authors present a retrospective analysis of 58 cases of tetanus hospitalized in two ICU in 13 years of activity. The mortality reported (39.7%) is comparable to other Authors or statistical analysis but it is better if correlated to patient age.

[Hypoxia and oxygen content during dialysis].

In a study of 72 patients treated with acetate and bicarbonate dialysis, the Authors verified if hypoxic hypoxia caused by dialysis depends on a deficit in oxygen content with an inherent risk of tissue hypoxia. PO2uv (uncompensated venous oxygen partial pressure) and CQ (cardiac compensation factor) derived from the oxygen absorption curve were studied by a new Ole Siggard-Andersen algorithm. The results do not show a risk of tissue hypoxia in the postdialytic period.

[Anoxic-ischemic encephalopathy and myoclonic status epilepticus].

The Authors present a case of post-anoxic coma accompanied by myoclonic status. They describe the clinical picture and instrumental data. The outcome seems to be determined by the serious anoxic-pathological damage rather than the myoclonic jerks.

[Cardiac tamponade: an unusual cause. Clinical case].

The Authors describe an unusual case of acute cardiac tamponade caused by fistulization in the pericardial cavity of an amebic abscess of the left lobe of the liver. The availability of echocardiography facilitated prompt diagnosis and treatment.
