The Prevalence of Neck and Back Pain among Paramedics in Poland

Neck Pain (NP) and low back pain (LBP) are ubiquitous musculoskeletal conditions and some of the major causes of disability worldwide. The aim of the study was to assess the incidence and risk factors of back pain among paramedics and their correlation with the nature of work, anthropometric features and the level of recreational physical activity. A group of 201 individuals (39 females (19.40%); 162 males (80.60%)), licensed to practice as paramedics in Poland completed a questionnaire containing the author’s interview as well as the Neck Disability Index (NDI) questionnaire and the Revised Oswestry Disability Index (ODI). Among the examined paramedics, 92% of the subjects reported the presence of back pain in different parts of the spine (36% C; 17% Th; and 85% LBP). The pain intensity, determined by VAS, was on average 4.26 (SD 1.77). The level of disability, assessed by NDI, was 7.67 (SD 5.73) on average, while the ODI was 7.51 (5.90). Work-related spinal strain has a major impact on the intensity and incidence of spinal pain. Spinal pain in paramedics mainly occurs in the lower back

Nodularia spumigena Peptides—Accumulation and Effect on Aquatic Invertebrates

Thus far, the negative effects of Nodularia spumigena blooms on aquatic organisms have been mainly attributed to the production of the hepatotoxic nodularin (NOD). In the current work, the accumulation of other N. spumigena metabolites in blue mussels and crustaceans, and their effect on Thamnocephalus platyurus and Artemia franciscana, were examined. The liquid chromatography-tandem mass spectrometry (LC-MS/MS) analyses provided evidence that both blue mussels collected after a cyanobacterial bloom in the Baltic Sea and the crustaceans exposed under laboratory conditions to N. spumigena extract accumulated the cyclic anabaenopeptins (APs). In the crustaceans, the linear peptides, spumigins (SPUs) and aeruginosins (AERs), were additionally detected. Exposure of T. platyurus and A. franciscana to N. spumigena extract confirmed the negative effect of nodularin on the organisms. However, high numbers of dead crustaceans were also recorded in the nodularin-free fraction, which contained protease inhibitors classified to spumigins and aeruginosins. These findings indicate that cyanobacterial toxicity to aquatic organisms is a complex phenomenon and the induced effects can be attributed to diverse metabolites, not only to the known hepatotoxins
