Human studies have demonstrated a correlation between noncoding polymorphisms of "the pain protective" haplotype in the GCH1 gene that encodes for GTP cyclohydrolase I (GTPCH1)-which leads to reduced tetrahydrobiopterin (BH4) production in cell systems-and a diminished perception of experimental and clinical pain. Here, we investigate whether heterozygous mutations in the GCH1 gene which lead to a profound BH4 reduction in patients with dopa-responsive dystonia (DRD) have any effect on pain sensitivity. The study includes an investigation of GCH1-associated biomarkers and pain sensitivity in a cohort of 22 patients with DRD and 36 controls. ⋯ The patients with DRD were heterozygous for the pain protective haplotype in cis with the GCH1 disease-causing mutation, c.899T>C. No effect on pain perception was observed for this combined haplotype. In conclusion, a reduced concentration of BH4 is not sufficient to alter ongoing pain sensitivity or evoked pain responses.

Sepsis remains the leading cause of morbidity and mortality in intensive care units. The extracorporeal therapy in the complex treatment of sepsis seems to be the most promising direction. The aim of this study was to assess the safety and effectiveness of selective endotoxin adsorption on the basis of the analysis of our own experience with the intensive therapy for sepsis in adult cardiac surgical patients. ⋯ The 28-day survival was 53% in the study group and 30% in the control group (P = 0.037). The 28-day survival of children who received selective hemoperfusion was 90%. Our own experience with the use of selective hemoperfusion in a fairly large group of cardiovascular patients with sepsis showed the safety and efficacy of these procedures.

Cancer immunotherapy efficacy and patients' sex: a systematic review and meta-analysis.
Despite the acknowledged sex-related dimorphism in immune system response, little is known about the effect of patients' sex on the efficacy of immune checkpoint inhibitors as cancer treatments. We did a systematic review and meta-analysis to assess the heterogeneity of immune checkpoint inhibitor efficacy between men and women. ⋯ None.
