Lipid profile changings after switching from rilpivirine/tenofovir disoproxil fumarate/ emtricitabine to rilpivirine/tenofovir alafenamide/emtricitabine: Different effects in patients with or without baseline hypercholesterolemia
open10noTenofovir alafenamide (TAF) has similar efficacy compared to tenofovir disoproxil fumarate (TDF), but a less favorable effect on lipids. Aim of this retrospective multicentre study was to evaluate the impact on lipids of switching from rilpivirine (RPV)/ emtricitabine (FTC)/TDF to RPV/FTC/TAF in a cohort of HIV-1 infected patients. Total cholesterol (TC), high density lipoproteins (HDL) and low density lipoproteins (LDL) were compared at the moment of the switch and at the first following evaluation, by using paired t-test. Overall, 573 patients were considered, 99% with HIV-RNA <50 copies/ml, with mean age of 49.7 (±0.4) years and median 13.4 (6.9-22.5) years of HIV infection. In the study population with available data (431/573, 75%), mean TC changed from 173 ±1.7 to 188 ±1.8 mg/dl; mean HDL from 46 ±0.7 to 51± 0.7 mg/dl; mean LDL from 111 ±1.5 to 120 ±1.8 mg/dl (p<0.0001 for all). Neither LDL/HDL nor TC/HDL ratio changed significantly, with LDL/HDL from 2.6 ±0.5 to 2.5 ±0.5 (p = 0.12) and TC/HDL from 4.0 ±0.6 to 3.9 ±0.6 (p = 0.11). In patients with baseline diagnosis of hypercholesterolemia (TC>200 mg/dl, N = 87), there was no significant change in TC (224 ±2.2 to 228 ±3.4 mg/dl, p = 0.286) or LDL (150±2.5 to 151±3.2 mg/dl, p = 0.751), while HDL increased from 51 ±1.6 to 55 ±1.7 mg/dl (p<0.0001) and both LDL/HDL and TC/HDL ratio decreased significantly, from 3.2±0.1 to 3.0 ±0.1 (p = 0.025) and from 4.7±0.1 to 4.4 ±0.1 (p = 0.004). In this real life study, a slight increase in lipids was found after switching from RPV/FTC/TDF to RPV/FTC/TAF, but these results were not confirmed in people with hypercholesterolemia, in which lipids did not change and LDL/HDL and TC/HDL ratio decreased.openTaramasso L.; Di Biagio A.; Riccardi N.; Briano F.; Di Filippo E.; Comi L.; Mora S.; Giacomini M.; Gori A.; Maggiolo F.Taramasso, L.; Di Biagio, A.; Riccardi, N.; Briano, F.; Di Filippo, E.; Comi, L.; Mora, S.; Giacomini, M.; Gori, A.; Maggiolo, F
Lipid profile changings after switching from rilpivirine/tenofovir disoproxil fumarate/emtricitabine to rilpivirine/tenofovir alafenamide/emtricitabine: different effects in different patients populations. Results from a large observational study
Tenofovir alafenamide (TAF) has similar efficacy compared to tenofovir disoproxil fumarate (TDF),
but a less favorable effect on lipids. Aim of this study was to evaluate the impact on lipids of switching from
rilpivirine (RPV)/ emtricitabine (FTC)/TDF to RPV/FTC/TAF in a large cohort of HIV-1 infected patients
Fractionation of polydisperse systems: multi-phase coexistence
The width of the distribution of species in a polydisperse system is employed
in a small-variable expansion, to obtain a well-controlled and compact scheme
by which to calculate phase equilibria in multi-phase systems. General and
universal relations are derived, which determine the partitioning of the fluid
components among the phases. The analysis applies to mixtures of arbitrarily
many slightly-polydisperse components. An explicit solution is approximated for
hard spheres.Comment: 4 pages, 1 figur
stress response system and personality in rheumatoid arthritis patients
Various factors such as immunogenetic determinants, sex, age and stress paly an important role in the pathogenesis of rheumatoid arthritis (RA). The relationship between stress and RA is still unclear and undefined; however, various lines of research are developing in order to evaluate environmental, psychologic, and biologic stressors as predisposing factors. The aim of our study was to evaluate whether stress-related psychologic factors and personality disorders might be involved in the development of RA, by using a psychometric investigation-methodology in a series of patients. Twenty-three patients underwent a clinical inteview and other specific psychometric tests. Macro and microstressful life-events preceded RA in 83% of the cases. Sixty percent of the patients showed a correlation between flare-ups of the disease and appearance of microevents. An obsessive-compulsive personality was found in 26% of the patients. Anxia was detected in 40% of the patients. Among the group of patients with borderline disorder's was also detected alexithymia. The high prevalence of major life-events preceding the onset of RA and the presence of personality disorders support the role of the altered stress response system as an importunat pathogenetic factor in the disease

Reactivation of Herpes Simplex Virus Type 1 (HSV-1) Detected on Bronchoalveolar Lavage Fluid (BALF) Samples in Critically Ill COVID-19 Patients Undergoing Invasive Mechanical Ventilation: Preliminary Results from Two Italian Centers
Reactivation of herpes simplex virus type 1 (HSV-1) has been described in critically ill patients with coronavirus disease 2019 (COVID-19) pneumonia. In the present two-center retrospective experience, we primarily aimed to assess the cumulative risk of HSV-1 reactivation detected on bronchoalveolar fluid (BALF) samples in invasively ventilated COVID-19 patients with worsening respiratory function. The secondary objectives were the identification of predictors for HSV-1 reactivation and the assessment of its possible prognostic impact. Overall, 41 patients met the study inclusion criteria, and 12/41 patients developed HSV-1 reactivation (29%). No independent predictors of HSV-1 reactivation were identified in the present study. No association was found between HSV-1 reactivation and mortality. Eleven out of 12 patients with HSV-1 reactivation received antiviral therapy with intravenous acyclovir. In conclusion, HSV-1 reactivation is frequently detected in intubated patients with COVID-19. An antiviral treatment in COVID-19 patients with HSV-1 reactivation and worsening respiratory function might be considered

Development of a new CEDAR for kaon identification at the NA62 experiment at CERN
The NA62 experiment at CERN utilises a differential Cherenkov counter with achromatic ring focus (CEDAR) for tagging kaons within an unseparated monochromatic beam of charged hadrons. The CEDAR-H detector was developed to minimise the amount of material in the path of the beam by using hydrogen gas as the radiator medium. The detector was shown to satisfy the kaon tagging requirements in a test-beam before installation and commissioning at the experiment. The CEDAR-H performance was measured using NA62 data collected in 2023
