Abstract Background Before the COVID-19 pandemic, Sexually transmitted infections (STIs) were increasing in Europe, and Spain Catalonia not an exception. has been one of regions with highest number confirmed cases Spain. The objective this study was to estimate magnitude decline, due STI during lockdown de-escalation phases. Methods Interrupted time series analysis performed decline reported - chlamydia, gonorrhoea, syphilis, lymphogranuloma venereum- since historical data, from March 13th...

Type 1 diabetes (T1D) is a chronic metabolic disease characterized by the autoimmune destruction of β-cells in pancreatic islets. T1D preceded islet-specific inflammation led several immune cells. Among them, natural killer (NK) cells are emerging as important players development.

The lack of continuity between health-related quality life (HRQoL) instruments designed for children and adults hinders change analysis with a course approach. To resolve this gap, EuroQol (EQ) developed the EQ-5D-Youth (EQ-5D-Y), derived from EQ-5D adults. Few studies have assessed metric properties EQ-5D-Y in specific chronic conditions, none done so type I diabetes mellitus (T1DM).This study aimed to evaluate acceptability, validity, reliability, responsiveness adolescents T1DM, when...

The partial remission (PR) phase, a period experienced by most patients with type 1 diabetes (T1D) soon after diagnosis, is characterized low insulin requirements and improved glycemic control. Given the great potential of this phase as therapeutic window for immunotherapies because its association immunoregulatory mechanisms β-cell protection, our objective was to find peripheral immunological biomarkers better characterization, monitoring, prediction. longitudinal follow-up 17 pediatric...

Exosome-derived miR-21 was independently associated with CD4 T cell decline in HIV-1-infected elite controllers (OR 0.369, 95% CI 0.137-0.994, p = 0.049). Also, a negative correlation between expression and MCP-1 level found (r -0.649, 0.020), while no soluble biomarkers or cellular immune activation found.

The partial remission (PR) phase of type 1 diabetes (T1D) is an underexplored period characterized by endogenous insulin production and downmodulated autoimmunity. To comprehend the mechanisms behind this transitory develop precision medicine strategies, biomarker discovery patient stratification are unmet needs. MicroRNAs (miRNAs) small RNA molecules that negatively regulate gene expression modulate several biological processes, functioning as biomarkers for many diseases. Here, we identify...
