Twelve days after the Great East Japan Earthquake, as the Fukushima Daiichi Nuclear Power Plant crisis was unfolding, we began a survey to examine the physical and mental state of medical staff to assess their motivation toward work. Surveys were administered in March 2011 (Survey 1), March 2012 (Survey 2), March 2013 (Survey 3), March 2014 (Survey 4), and March 2015 (Survey 5). Participants completed the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), EuroQol (EQ-5D), and MOS Short-Form 36-item Health Survey (SF-36). Although BDI scores significantly improved over time following Survey 1, participants in their 30s had significantly higher Survey 2 scores than those in their 40s/50s, and significantly higher Survey 3 scores than those in their 20s. STAI scores significantly improved over time following Survey 1. However, participants in their 30s had significantly higher Survey 3 scores than those in their 20s. EQ-5D scores did not significantly vary among survey time points or age groups. SF-36 physical functioning, role physical, social functioning, role emotional, and mental health subscale scores significantly improved over time. In conclusion, post-disaster longitudinal changes, including recovery period, differed among age groups.

However, as oxaliplatin and paclitaxel are common neurotoxic drugs, chemotherapy-induced peripheral neuropathy (CIPN) is a common and severe adverse effect of both treatments.

The efficacy of duloxetine was observed in a large randomized controlled trial (RCT). In addition, pregabalin was more effective than duloxetine for CIPN in two RCTs. Although duloxetine and pregabalin can be effective for CIPN, they have several side effects. Therefore, the choice between the two drugs should be determined according to effect and tolerability.
