Oxidative stress often occurs in chronic hemodialysis (HD) patients. The objective of our study was to investigate the interrelationship between oxidative stress and the degree of renal anemia.', 'In 107 consecutive HD patients, serum concentrations of two major aldehydic lipid peroxidation (LPO) products, 4-hydroxynonenal (HNE) and malondialdehyde (MDA), and of protein carbonyls were analyzed as parameters of oxidative stress and related to the degree of renal anemia. Additionally, in 76 patients treated with epoetin long-term changes in the serum levels of aldehydic LPO products were observed.', 'In HD patients, serum levels of HNE, MDA, and protein carbonyls are increased in comparison to controls. The lower the hemoglobin, i.e. the stronger the degree of renal anemia, the higher the serum concentrations of HNE, MDA, and protein carbonyls. The HNE and MDA levels decreased during HD. Long-term studies on the correction of renal anemia by epoetin demonstrated a mitigation of oxidative stress during this therapy. During periods of 1 and 2 years, it was observed that the serum levels of HNE and MDA could be reduced.

To determine whether the number of words displayed in the word prediction software (WPS) list affects text input speed (TIS) in people with cervical spinal cord injury (SCI), and whether any influence is dependent on the level of the lesion.', 'A cross-sectional trial.', 'A rehabilitation center.', 'Persons with cervical SCI (N=45). Lesion level was high (C4 and C5, American Spinal Injury Association [ASIA] grade A or B) for 15 participants (high-lesion group) and low (between C6 and C8, ASIA grade A or B) for 30 participants (low-lesion group).', 'TIS was evaluated during four 10-minute copying tasks: (1) without WPS (Without); (2) with a display of 3 predicted words (3Words); (3) with a display of 6 predicted words (6Words); and (4) with a display of 8 predicted words (8Words).', 'During the 4 copying tasks, TIS was measured objectively (characters per minute, number of errors) and subjectively through subject report (fatigue, perception of speed, cognitive load, satisfaction).', 'For participants with low-cervical SCI, TIS without WPS was faster than with WPS, regardless of the number of words displayed (P<.001). For participants with high-cervical SCI, the use of WPS did not influence TIS (P=.99). There was no influence of the number of words displayed in a word prediction list on TIS; however, perception of TIS differed according to lesion level.

Japanese in-patients with pulmonary tuberculosis and normal liver function receiving treatment with isoniazid and rifampicin (INH + RMP).', 'To elucidate the relationship between N-acetyltransferase 2 (NAT2) genotype and the incidence of isoniazid + rifampicin-induced hepatotoxicity.', 'Prospective study. After NAT2* genotyping, 77 patients were classified into three groups according to their NAT2* genotypes: rapid-type (a homozygote of NAT2*4), intermediate-type (a heterozygote of NAT2*4 and mutant alleles) and slow-type (a combination of mutant alleles). Their biochemical profiles of liver function test were investigated for 3 months to assess the development of serum aminotransferase elevation.', 'Of the 77 patients, 18.2% developed adverse hepatic reaction within the first month of INH + RMP treatment. A significant association was observed between hepatotoxicity and NAT2* genotype: compared with rapid-type, the relative risk was 4.0 (95% CI 1.94-6.06) for intermediate-type and 28.0 (95%CI 26.0-30.0) for slow-type. Especially in slow-type, the incidence of hepatotoxicity and serum aminotransferase elevation was significantly higher than in the other two types.
