Faint (and bright) variable stars in the satellites of the Milky Way

EPJ Web of Conferences, 2017
I describe two ongoing projects related with variable stars in the satellites of the MilkyWay. In the first project, we are searching for dwarf Cepheid stars (a.k.a δ Scuti and/or SX Phe) in some of the classical dwarf spheroidal galaxies. Our goal is to

HCV Testing and Treatment of Adults in the United States: 2014 Through 2021—Data From Two National Commercial Testing Laboratories

Journal of Viral Hepatitis, Volume 32, Issue 11, November 2025.
ABSTRACT Data on the hepatitis C virus (HCV) care cascade are crucial for determining if the United States (U.S.) is on track to meet 2016 World Health Organization elimination goals. De‐identified data were analysed from persons who were screened for HCV antibody and/or tested for HCV RNA by two large U.S.

Fundamentalization of Periods for First- and Second-overtone Classical Cepheids

The Astrophysical Journal Letters
Almost half of all classical Cepheids do not pulsate in fundamental mode, and nowadays, the fundamentalization of their higher-mode periods is frequently applied to increase the sample size in astrophysical investigations and allow for comparison with ...

High Efficiency and Safety of Hepatitis C Treatment Among People Who Inject Drugs in Vietnam

Journal of Viral Hepatitis, Volume 32, Issue 11, November 2025.
ABSTRACT People who inject drugs (PWID) are highly affected by hepatitis C (HCV) worldwide, particularly in low‐ and middle‐income countries (LMICs), where access to addiction services is often limited. Reducing the burden of HCV, as promoted by WHO, requires effective interventions in this high‐risk population.

Systematics in the Cepheid and TRGB Distance Scales: Metallicity Sensitivity of the Wesenheit Leavitt Law

The Astrophysical Journal
Using an updated and significantly augmented sample of Cepheid and tip of the red giant branch (TRGB) distances to 28 nearby spiral and irregular galaxies, covering a wide range of metallicities, we have searched for evidence of a correlation of the zero-

Performance Evaluation of the Elecsys HCV Duo Immunoassay in the Public Healthcare Setting in Cape Town, South Africa

Journal of Viral Hepatitis, Volume 32, Issue 11, November 2025.
ABSTRACT Improved HCV diagnosis and linkage to care is crucial to achieve WHO 2030 elimination targets. Simplification of diagnostics remains key. We evaluated the performance of Elecsys HCV Duo antigen/antibody immunoassay in patients using public healthcare in Cape Town, South Africa. 253 HCV seropositive and 214 seronegative samples were tested, and

Risk Factors of Progression to Active Tuberculosis in Rheumatic Patients With Latent Tuberculosis: A Retrospective Study

Immunity, Inflammation and Disease, Volume 13, Issue 10, October 2025.
ABSTRACT Background In rheumatism patients, the immune system erroneously attacks the body′s own tissues. This impairs the body′s defense against external pathogens and is a contributing factor to the occurrence of tuberculosis infection. The primary objective of this investigation was to examine the risk factors for the progression from latent ...

OGLE-IV Period–Luminosity Relation of the LMC: An Analysis Using Mean and Median Magnitudes

The Astronomical Journal
The Period–Luminosity (PL) relation for Cepheid variable stars in the LMC is crucial for distance measurements in astronomy. This study analyzes the impact of using the median rather than the mean of the PL relation’s slope and zero-point.

Non-particle dark matter from Hubble parameter

European Physical Journal C: Particles and Fields, 2019
The measurements of the Hubble parameter using the cosmic microwave background radiation appear to be inconsistent with the measurements of this parameter using Cepheid variable stars.

Treatment variations in localised prostate cancer in Australia and New Zealand: a registry study

BJU International, Volume 136, Issue S2, Page S62-S69, October 2025.
Objective To describe the patterns of care and factors associated with treatment uptake of localised prostate cancer, using the bi‐national Prostate Cancer Outcomes Registry–Australia and New Zealand (PCOR‐ANZ) database. Methods Data for 36 504 patients, diagnosed between 2015 and 2018, from New Zealand and seven Australian jurisdictions were evaluated.
