RESUMEN
Musculoskeletal (MSK) diseases affect a substantial proportion of the population. Specialist consultations were offered at the workplace for people with musculoskeletal (MSK)-complaints. We analyzed data on pain and well-being as well as health economic data at baseline. Lasting effects of the consultation were analyzed at a follow-up-interview after 12 months. Baseline data of 344 individuals were available. Occupations were divided into physically highly demanding (HD) or less demanding. Women reported significantly higher pain levels and less QoL than men. Sick leave days were significantly more in HD-workers. Independent of workload, significantly higher percentages of women had cervical- and upper limb-pain than men, with significantly higher pain in upper limbs in HD-workers. 235 participants were available for telephone-follow-up. QoL and MSK-pain improved significantly. Yearly out-of-pocket spendings for treatments significantly increased. NSAID use significantly decreased, whereas use of non-drug musculoskeletal-medical-services was significantly higher after one year. Regarding MSK-symptoms in gainfully employed individuals, the study showed significantly different workload-dependent differences in QoL. Significant effects of a consultation by a MSK-specialist were shown in terms of improved MSK-pain and overall well-being. This workplace-centered consultation had significant effects on beneficial health-behavior such as decreased use of NSAID and increased engagement in gymnastics and physiotherapy.

In early clinical testing, acute addition of alanyl-glutamine (AlaGln) to glucose-based peritoneal dialysis (PD) fluids restored peritoneal cellular stress responses and leukocyte function. This study was designed to test the effect of extended treatment with AlaGln-supplemented PD fluid on biomarkers of peritoneal health. In a double-blinded, randomized crossover design, stable PD patients were treated with AlaGln (8 mM) or placebo added to PD fluid for eight weeks. As primary outcome measures, dialysate cancer-antigen 125 (CA-125) appearance rate and ex vivo stimulated interleukin-6 (IL-6) release were assessed in peritoneal equilibration tests. In 8 Austrian centers, 54 patients were screened, 50 randomized, and 41 included in the full analysis set. AlaGln supplementation significantly increased CA-125 appearance rate and ex vivo stimulated IL-6 release. AlaGln supplementation also reduced peritoneal protein loss, increased ex vivo stimulated tumor necrosis factor (TNF)-α release, and reduced systemic IL-8 levels. No adverse safety signals were observed. All 4 peritonitis episodes occurred during standard PD fluid treatment. A novel AlaGln-supplemented PD fluid improves biomarkers of peritoneal membrane integrity, immune competence, and systemic inflammation compared to unsupplemented PD fluid with neutral pH and low-glucose degradation. A phase 3 trial is needed to determine the impact of AlaGln supplementation on hard clinical outcomes.
