In the aftermath of disasters in areas where populations live in close proximity and where sanitation and water supplies are compromised, an environment is created which is conducive to epidemics of vaccine-preventable diseases.
A strong earthquake occurred in Haiti in January 2010, severely affecting Port au Prince, the capital of the country, and the Government was functionally damaged. Over 220,000 people lost their lives and over 300,000 were injured.
Around 1.3 million people are living in temporary shelters in the Port-au-Prince metropolitan area and over 500,000 people have left the disaster areas to seek refuge in the rest of the country.
In Haiti, one of the world's most impoverished countries, the weak routine vaccination coverage was noted and the vaccination campaign was concerned as one of the first priorities.
The Japanese Red Cross (JRC) sent a medical team, called an ERU (Emergency Response Unit) right after the earthquake and provided medical services such as clinics in affected areas.
At the same time, we were involved in the vaccination campaign as one of the key players in the International Federation of the Red Cross and Red Crescent Societies (IFRC) in responding to the mass vaccination campaign by the Ministry of Health supported by WHO (World Health Organization) and UNICEF.
More than 150,000 people were vaccinated in 1 month by all Red Cross members. 35,217 of them were by JRC and the coverage was 75.5% according to the random survey. Including all the activities, it took more than 3 months and 62% of initially estimated population was vaccinated until the end.
After disasters, people typically move to other places seeking a better environment so mass vaccination campaign has to be carried out immediately, once it is decided upon. The selection of target populations, vaccines and good cooperation with other organizations is the key to success.

To evaluate the association of serum BDNF concentration with high-intensity interval training, 12 healthy male volunteers, aged 28-48 years, completed 16-week high-intensity interval training (HIIT) using ergometer. Training program consisted of >90% VO2 peak for 60 sec separated by 60 sec active rest period for 8-12 sets twice weekly for 16-week. Maximal exercise tolerance tests were performed before (0-week), 4-week, and 16-week after the intervention program. VO2 peak as well as peak watt was linearly increased after 4-week (9% for both VO2 peak and peak watt) and 16-week HIIT training (15% for VO2 peak and 18% for peak watt, p<0.01). However, there was no change in serum BDNF concentration by HIIT. On the other hand, there was a positive association of serum BDNF concentration at baseline with % increase in peak watt after the intervention (ρ=0.60, p<0.05). The association between BDNF and exercise training is still unclear, and more studies are needed to clarify the above positive association.

BACKGROUND/AIMS: Recent genome-wide analyses have provided strong evidence concerning adverse events caused by thiopurine drugs such as azathioprine (AZA) and 6-mercaptopurine. The strong associations identified between NUDT15 p.Arg139Cys and thiopurine-induced leukopenia and severe hair loss have been studied and confirmed over the last 2 years. However, other coding variants, including NUDT15 p.Val18_Val19insGlyVal, NUDT15 p.Val18Ile, and FTO p.Ala134Thr, and a noncoding variation in RUNX1 (rs2834826) remain to be examined in detail in this respect. Therefore, we investigated the correlation between these adverse events and the 5 recently identified variants mentioned above among Japanese patients with inflammatory bowel diseases (IBD). METHODS: One hundred sixty thiopurine-treated patients with IBD were enrolled. Genotyping was performed using TaqMan SNP Genotyping Assays or Sanger sequencing. RESULTS: None of the 5 variants were associated with gastrointestinal intolerance to AZA. However, NUDT15 p.Arg139Cys was significantly associated with the interval between initiation and discontinuation of AZA among patients with gastrointestinal intolerance. This variant was strongly associated with early (<8 weeks) and late (≥8 weeks) leukopenia and severe hair loss. Moreover, it correlated with the interval between initiation of thiopurine therapy and leukopenia occurrence, and average thiopurine dose. NUDT15 p.Val18_Val19insGlyVal, NUDT15 p.Val18Ile, FTO p.Ala134Thr, and RUNX1 rs2834826 exhibited no significant relationship with the adverse events examined. CONCLUSIONS: Of the 5 variants investigated, NUDT15 p.Arg139Cys had the strongest impact on thiopurine-induced leukopenia and severe hair loss; therefore, its genotyping should be prioritized over that of other variants in efforts to predict these adverse events in Japanese patients with IBD.
