Organ allocation in Japan remains difficult due to the shortage of deceased-donor livers. The screening tool for controlling nutritional status (CONUT) has been considered to be an established assessment model for evaluating nutritional aspects in surgical patients. However, the application of this CONUT for evaluating the prognosis of patients with end-stage liver diseases has not been evaluated. We assessed the predictability of the prognoses of 58 patients with end-stage liver disease using various prognostic models. The patients registered at the transplantation center of Tohoku University Hospital for the waiting list of Japan Organ Transplant Network for liver transplantation were retrospectively analyzed. The prognoses of the patients were evaluated using the following 5 models: CONUT, the model for ELD with incorporation of sodium (MELD-Na), Child-Turcotte-Pugh score (CTP), prognostic nutritional indices (Onodera: PNI-O), and the Japan Medical Urgency criteria of the liver (JMU). Cox's proportional hazard model, log-rank test and concordance(c)-static were used for the statistics. The indices were 17.74 ± 5.80 for MELD-Na, 9.21 ± 2.19 for CTP, 33.92 ± 11.16 for PNI-O, and 7.57 ± 3.09 for CONUT. Univariate analysis revealed the significance of CONUT (p = 0.017, Odds: 1.325) but not MELD-Na, CTP, JMU or PNI-O for prediction. The cumulative survival rate was clearly discriminated at CONUT point 7. The c-static was 0.081 for the 6-month (M) survival rate, 0.172 for 12M, 0.517 for 36M, 0.821 for 48M, and 0.938 for 60M for CONUT. In conclusion, CONUT shows best predictability for the distant prognoses of patients with ELD.
In patients with nonviral CLD, LSM was most helpful in predicting significant fibrosis (F >or= 2). Transient elastography is a reliable method for predicting significant liver fibrosis, not only in CHC patients but also in nonviral CLD patients.
The addition of gibberellin A3 (GA3) to culture media induced a dramatic elongation of the first internode in Hong Mang Mai, a wheat variety tolerant to deep‐seeding conditions. The length of the first internode in the GA3‐treated seedlings reached approximately 45 cm, which is twice as long as that of the control, whereas first internodes of other varieties were 3 to 12 cm long and hardly affected by GA3. The level of endogenous gibberellins (GA) in Hong Mang Mai was not greater than that of other wheat varieties. The expression of GAMyb, a transcription factor, was abundant in the first internode and substantially increased by GA3 application in Hong Mang Mai, compared with other wheat varieties. These results suggest that the first internode of Hong Mang Mai is more sensitive to GA in inducing strong elongation. The presence of potassium in the culture media was indispensable for the first internode elongation. Application of GA3 enhanced the uptake of potassium in Hong Mang Mai. Higher sensitivity of the first internode to GA could cause strong elongation by increasing the amount of osmotic solute, which plays an important role in the tolerance mechanism of Hong Mang Mai to deep‐seeding conditions.
To investigate the efficacy of long-term lamivudine (3TC) and adefovir dipivoxil (ADV) combination therapy in 3TC-resistant chronic hepatitis B virus (HBV) infected patients, we analysed 28 3TC-resistant patients treated with the combination therapy during 47 months (range, 9-75). At 12, 24, 36, and 48 months, the rates of virological response with undetectable HBV DNA (≤ 2.6 log copies/mL) were 56, 80, 86, and 92%, respectively. Among 17 hepatitis B e antigen (HBeAg)-positive patients, HBeAg disappeared in 24% at 12 months, 25% at 24 months, 62% at 36 months, and 88% at 48 months. When HBV genotypes were compared, patients with genotype B achieved virological response significantly more rapidly than those with genotype C (P=0.0496). One patient developed virological breakthrough after 54 months, and sequence analysis of HBV obtained from the patient was performed. An rtA200V mutation was present in the majority of HBV clones, in addition to the 3TC-resistant mutations of rtL180M+M204V. The rtN236T ADV-resistant mutation was observed in only 25% clones. In vitro analysis showed that the rtA200V mutation recovered the impaired replication capacity of the clone with the rtL180M+M204V mutations and induced resistance to ADV. Moreover, rtT184S and rtS202C, which are known entecavir-resistant mutations, emerged in some rtL180M+M204V clones without rtA200V or rtN236T. In conclusion, 3TC+ADV combination therapy was effective for most 3TC-resistant patients, especially with genotype B HBV, but the risk of emergence of multiple drug-resistant strains with long-term therapy should be considered. The mutation rtA200V with rtL180M+M204V may be sufficient for failure of 3TC+ADV therapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
