Particle-yield modification in jet-like azimuthal di-hadron correlations in Pb-Pb collisions at = 2.76 TeV
The yield of charged particles associated with high- trigger
particles ( GeV/) is measured with the ALICE detector in
Pb-Pb collisions at = 2.76 TeV relative to proton-proton
collisions at the same energy. The conditional per-trigger yields are extracted
from the narrow jet-like correlation peaks in azimuthal di-hadron correlations.
In the 5% most central collisions, we observe that the yield of associated
charged particles with transverse momenta GeV/ on the
away-side drops to about 60% of that observed in pp collisions, while on the
near-side a moderate enhancement of 20-30% is found.Comment: 15 pages, 2 captioned figures, 1 table, authors from page 10,

Symptom severity and quality of life in the management of vulvovaginal atrophy in postmenopausal women
Objectives: To evaluate the association between treatments for vulvovaginal atrophy (VVA) and symptom frequency
and severity, quality of life (QoL) and sexual functioning in postmenopausal women.
Study design: Cross-sectional survey conducted in postmenopausal women aged 45\u201375 years. Data on demographic
and clinical variables, as well as vaginal, vulvar and urinary symptoms were collected. The EuroQoL
questionnaire (EQ5D3L), the Day-to-Day Impact of Vaginal Aging (DIVA), the Female Sexual Function Index
(FSFI) and the Female Sexual Distress Scale - revised (FSDS-R) were filled out.
Main outcome measures: Association between treatments for VVA and symptom frequency.
Results: Women on VVA treatment presented with more severe symptoms. The sexual function score was higher
in the treated women (FSFI: 15.6 vs 16.7; p=0.010), as was the score for sexual distress (FSDS-R: 9.2 vs 12.3,
p < 0.0005). The systemic hormone group presented with fewer VVA symptoms, lower vaginal impact (DIVA),
and better sexual function (FSFI and FSDS-R) and vaginal health. The rates of sexual distress and vulvar atrophy
were higher in the non-hormonal treatment group. No significant differences were found according to treatment
duration. Conclusions: Postmenopausal women with VVA receiving treatment complained of more severe symptoms than
those untreated. Women on systemic treatment had fewer and milder VVA symptoms and presented with better
vaginal and vulvar health than women on other treatments. Many women request effective local treatment too
late, when VVA symptoms are already severe. Our data suggest that VVA treatments should ideally be initiated
when symptoms commence and cause distress, rather tha
Centrality Dependence of the Charged-Particle Multiplicity Density at Midrapidity in Pb-Pb Collisions at root s(NN)=2.76 TeV
The centrality dependence of the charged-particle multiplicity density at midrapidity in Pb-Pb collisions at root s(NN) = 2: 76 TeV is presented. The charged-particle density normalized per participating nucleon pair increases by about a factor of 2 from peripheral (70%-80%) to central (0%-5%) collisions. The centrality dependence is found to be similar to that observed at lower collision energies. The data are compared with models based on different mechanisms for particle production in nuclear collisions
