Burn injury is one of the most serious traumatic events with possible psychological and psychosocial consequences. Health status perception is one of the main health outcomes. The severity of psychological symptoms does not always correlate with that of the burn injury, suggesting that early screening for psychological vulnerabilities may be beneficial. The aim of our study was to identify the personality, clinical, and sociodemographic characteristics related to patient's subjective perception of health, depression, and anxiety in a sample of 52 adult patients with severe burn injury shortly before discharge from specialty burn clinic. Subjective health perception was predicted by depression (β = -.143, t(47) = -3.94, P < .001) and neuroticism (β = -.106, t(43) = -4.83, P < .001), and it correlated positively with extraversion (r = .2858, P = .0465) and conscientiousness (r = .3663, P = .0096). Depression was predicted by neuroticism (F(1,49) = 18.4; P < .001) and correlated with attachment avoidance (r = .29, P = .0383) and negatively with extraversion (r = -.32, P = .0220). Anxiety was related to attachment anxiety (F(1,49) = 4.25; P = .045), neuroticism (F(1,49) = 15.75; P < .001), and agreeableness (r = -.36, P = .0101). Unemployed patients experienced higher levels of depression and anxiety. This research suggests that personality traits and adult attachment may play an important role in the acute phase of the recovery from a severe burn injury. These findings can be relevant for early intervention and holistic rehabilitation.

5-fluorouracil (5-FU) and capecitabine therapy is often accompanied by palmar-plantar erythrodysesthesia (PPE) which is manifestation of 5-FU toxicity in keratinocytes. The main mechanisms of 5-FU action are thymidylate synthase (TS) inhibition which can be abrogated by thymidine and strengthened by calciumfolinate (CF) and incorporation of fluorouridinetriphosphate into RNA which can be abrogated by uridine. For proper PPE treatment 5-FU mechanism of action in keratinocytes needs to be elucidated. We used the 5-FU toxicity modulators uridine, thymidine and CF to discover the mechanism of 5-FU action in human keratinocyte cell line HaCaT. To measure the cellular viability, we used MTT test and RTCA test. CF did not augment 5-FU toxicity and 5-FU toxicity was weakened by uridine. Therefore, the primary mechanism of 5-FU toxicity in keratinocytes is 5-FU incorporation into RNA. The uridine protective effect cannot fully develop in the presence of CF. Thymidine addition to 5-FU and uridine treated cells not only prevents the toxicity-augmenting CF effect but it also prolongs the 5-FU treated cells survival in comparison to uridine only. Therefore, it can be assumed that in the presence of uridine the 5-FU toxicity mechanism is switched from RNA incorporation to TS inhibition. Although particular 5-FU toxicity mechanisms were previously described in various cell types, this is the first time when various combinations of pyrimidine nucleosides and CF were used for 5-FU toxicity mechanism elucidation in human keratinocytes. We suggest that for PPE treatment ointment containing uridine and thymidine should be further clinically tested.
