DGAT1 and DGAT2 Inhibitors for Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) Management: Benefits for Their Single or Combined Application.

Inhibiting diacylglycerol acetyltransferase (DGAT1, DGAT2) enzymes (iDGAT1, iDGAT2), involved in triglyceride (TG) synthesis, improves hepatic steatosis in metabolic dysfunction-associated steatotic liver disease (MASLD) patients. However, their potential synergism in disease onset (SLD) and progression (metabolic dysfunction-associated steatohepatitis, fibrosis) has been poorly explored. We investigated iDGAT1 and iDGAT2 efficacy, alone or combined (iDGAT1/2) on fat accumulation and hepatocellular injury in hepatocytes (HepG2) and on fibrogenic processes in hepatic stellate cells (LX2).

CAR+ extracellular vesicles predict ICANS in patients with B cell lymphomas treated with CD19-directed CAR T cells.

BACKGROUNDPredicting immune effector cell-associated neurotoxicity syndrome (ICANS) in patients infused with CAR T cells is still a conundrum. This complication, thought to be consequent to CAR T cell activation, arises a few days after infusion, when circulating CAR T cells are scarce and specific CAR T cell-derived biomarkers are lacking.METHODSCAR+ extracellular vesicle (CAR+EV) release was assessed in human CD19.

Peripheral blood cellular profile at pre-lymphodepletion is associated with CD19-targeted CAR-T cell-associated neurotoxicity.

Background: Infusion of second generation autologous CD19-targeted chimeric antigen receptor (CAR) T cells in patients with R/R relapsed/refractory B-cell lymphoma (BCL) is affected by inflammatory complications, such as Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS). Current literature suggests that the immune profile prior to CAR-T infusion modifies the chance to develop ICANS.

Methods: This is a monocenter prospective study on 53 patients receiving approved CAR T-cell products (29 axi-cel, 24 tisa-cel) for R/R-BCL.

Pre-transplant CD69+ extracellular vesicles are negatively correlated with active ATLG serum levels and associate with the onset of GVHD in allogeneic HSCT patients.

Graft versus host disease (GVHD) is a major complication of allogeneic hematopoietic stem cell transplantation (HSCT). Rabbit anti-T lymphocyte globulin (ATLG) in addition to calcineurin inhibitors and antimetabolites is a suitable strategy to prevent GVHD in several transplant settings. Randomized studies already demonstrated its efficacy in terms of GVHD prevention, although the effect on relapse remains the major concern for a wider use.

Combined Treatment with PI3K Inhibitors BYL-719 and CAL-101 Is a Promising Antiproliferative Strategy in Human Rhabdomyosarcoma Cells.

Rhabdomyosarcoma (RMS) is a highly malignant and metastatic pediatric cancer arising from skeletal muscle myogenic progenitors. Recent studies have shown an important role for AKT signaling in RMS progression. Aberrant activation of the PI3K/AKT axis is one of the most frequent events occurring in human cancers and serves to disconnect the control of cell growth, survival, and metabolism from exogenous growth stimuli.

The adverse effect profile and efficacy of divalproex sodium compared with valproic acid: a pharmacoepidemiology study.

Background: Divalproex sodium has been reported to be better tolerated than valproic acid. To our knowledge, no study has examined whether significant differences in the tolerability and efficacy exist between these preparations in psychiatric patients. The objective of the present study was to compare the tolerability and efficacy of divalproex sodium with those of valproic acid in psychiatric inpatients.

[Use of a microwave device for dental instrument sterilization: possibilities and limitations].

Background: The aim of the present study was the evaluation of the effectiveness as sterilizer of a modified version of a microwave device, which was previously tested by the same authors and found unsatisfactory.

Materials And Methods: Dental mirrors were contaminated by 10(4)-10(9) microorganisms of Stapbylococcus aureus and spores of Bacillus subtilis and Bacillus stearothermophilus. The inocula used were both wet and dry.

[The prevalence of anterior tooth trauma in children 6 to 11 years old].

The aim of the present paper was the study of prevalence of traumatic dental injuries to the anterior teeth of Italian schoolchildren. 519, 6- to 11-year-old children from two primary schools in Rome were examined, in order to evaluate dental injuries on canines and incisors. Traumatic injuries were classified according to Garcia-Godoy et al.

[A new device for the disinfection of handpieces and turbines].

Dental handpieces are often difficult to disinfect. This is one of the main reasons for the considerable risk of cross-infections in dental offices. The aim of the present study was the evaluation of the disinfectant property of a recent, commercially available, automatic instrument, described as capable to clean, disinfect and lubricate dental handpieces.

[3 different methods for evaluating Streptococcus mutans in the saliva].

Three different methods for detection and count of Streptococcus mutans in saliva have been compared with a microbiological method in order to estimate their efficacy and practicality. The study has been carried out on fifty children of six-eleven years old. The first method (stamp method) derives from that of Kohler and Bratthall, improved on the sampling, without saliva stimulation and, hence, more rapid.

[SARO: a system for irradiating small intracranial tumors under the guidance of magnetic resonance imaging].

An MR-based system for the accurate irradiation of small intracranial tumors, not less than 5 cm in diameter, is described. The system uses a home-made device (a support base with millimeter scales) and a series of thin individual wood moulds. A full size-enlargement of the central sagittal and of the tumor-containing transverse MR sections is the first operative step.

Intraluminal high dose rate brachytherapy combined with external radiotherapy in the treatment of oesophageal cancer.

Twenty eight patients with previously untreated oesophageal carcinoma without distant metastases were divided into two groups: Group A consisted of 18 pts. treated with conventional external radiotherapy only. Another group of 10 pts.

[The multidisciplinary treatment of rhabdomyosarcoma in childhood. A 10-year multicenter experience (1978-1988) in Liguria].

The authors retrospectively analyzed the therapy results in a large group of children affected by rhabdomyosarcoma and treated from 1978 to 1988 with chemotherapy, radiotherapy and surgery. 39/58 patients (67%) achieved a complete response and 25/39 maintained the NED status. An individualized treatment was given to 13 patients who relapsed, but only 3 of them obtained a second response.

[The clinical and microbiological evaluation of the efficacy of oral irrigation on the periodontal tissues of patients wearing fixed orthodontic appliances].

The aim of the present study has been the evaluation of the effectiveness of oral irrigation with or without toothbrushing and dental flossing, in individuals treated with fixed orthodontic appliances, on controlling the development of dental plaque and, hence, of gingivitis. Eight individuals with a good general and oral status have been chosen. Before the experimental period, they received instructions about oral hygiene with toothbrushing and dental flossing and then they have been monitored to verify they were doing well.

[High-dose gynecologic endocavitary brachytherapy. Technical and dosimetric aspects].

The technical and dosimetric aspects are presented of high-dose intracavitary brachytherapy in gynecology. Fifty-five patients (203 insertions) were examined over two years with a remote loading Selectron HDR 60Co unit installed in a dedicated bunker. The dose to the rectal and bladder markers on AP and LL films was calculated before every irradiation, in order to allow the necessary corrections to be made.
