Multicenter Study Clinical Trial
Advanced age and liability to oxaliplatin-induced peripheral neuropathy: post hoc analysis of a prospective study.
The aim of this post hoc analysis of data extracted from a prospective, multicenter study is to test in a large homogenous population of chemotherapy-naïve patients with colorectal cancer (CRC) treated with oxaliplatin (OXA)-based chemotherapy whether advanced age increases the risk of developing OXA-induced peripheral neuropathy (OXAIPN). ⋯ The results of this study indicate that advanced age does not seem to represent a significant risk factor of OXAIPN in patients with CRC without any other significant co-morbidities.

It has been hypothesized that exposure to anaesthetic agents, some of which are chemically related to organic solvents, may affect the risk of developing multiple sclerosis (MS). The aim of this study was to estimate the influence of occupational exposure to anaesthetic agents on the risk for MS. We further aimed to investigate the impact of general anaesthesia and usage of nitrous oxide. ⋯ Neither occupational exposure to anaesthetic agents, nor general anaesthesia or usage of nitrous oxide has any impact on MS risk and is safe also for people with a genetic susceptibility to the disease. However, further studies would be valuable in order to clarify whether other forms of organic solvents contribute to the triggering of MS.

Identification of the trigger factors of headache could be an important aspect of preventive management, but the characteristics of primary headache triggers in China are unknown. This study was performed to estimate the frequencies of the putative headache triggers, which are endorsed by patients with migraine and tension-type headache (TTH). ⋯ Trigger factors were frequent among both migraine and TTH patients. Avoidance of all headache triggers is impractical. Learning to cope with triggers is important to headache prevention.

Poor sleep is commonly associated with alterations in pain perception. However, there is a lack of studies that address work-associated sleep restriction (SR) and changes in non-nociceptive perception and autonomic responses after work-induced SR. ⋯ The effects of SR in the context of work stress on pain are specific and appear unrelated to general changes in sensory perception. Hyperalgesia was associated with abnormal autonomic responses, but not with increased anxiety, which suggests an association between the nociceptive and autonomic nervous systems that is independent of the emotional state.

Pre-existing brain infarct (PBI), frequently seen on magnetic resonance imaging and usually silent, is recognized as a risk factor for future stroke. Increased apolipoprotein B (apoB)/apoAI ratio is known to be a risk predictor of ischaemic stroke and is associated with intracranial atherosclerotic stenosis (ICAS). However, little is known about the association of apoB/apoAI ratio with PBI. ⋯ ApoB/apoAI ratio is associated with asymptomatic deep subcortical ischaemic burden as well as with symptomatic lesion in patients with ICAS.
