Background/aims Low-level viremia (LLV) after nucleos(t)ide analog treatment was presented as a possible cause of hepatocellular carcinoma (HCC) in patients with chronic hepatitis B (CHB). However, detailed information on patients' adherence in the real world was lacking. This study aimed to evaluate the effects of LLV on HCC development, mortality, and cirrhotic complications among patients according to their adherence to entecavir (ETV) treatment. Methods We performed a retrospective observational analysis of data from 894 consecutive adult patients with treatment-naïve CHB undergoing ETV treatment. LLV was defined according to either persistent or intermittent episodes of less then 2,000 IU/mL detectable hepatitis B virus DNA during the follow-up period. Good adherence to medication was defined as a cumulative adherence ≥90% per study period. Results Without considering adherence in the entire cohort (n=894), multivariate analysis of the HCC incidence showed that LLV was an independent prognostic factor in addition to other traditional risk factors in the entire cohort (P=0.031). Good adherence group comprised 617 patients (69.0%). No significant difference was found between maintained virologic response and LLV groups in terms of the incidence of liver-related death or transplantation, HCC, and hepatic decompensation in good adherence group, according to multivariate analyses. Selleckchem Rapamycin Conclusions In patients with treatment-naïve CHB and good adherence to ETV treatment in the real world, LLV during treatment is not a predictive factor for HCC and cirrhotic complications. It may be unnecessary to adjust their antiviral agent for patients with good adherence who experience LLV during ETV treatment.Methamphetamine (MA) is one of the most commonly abused drugs in the world by illegal drug users. Addiction to MA is a serious public health problem and effective therapies do not exist to date. It has also been reported that behavior induced by psychostimulants such as MA is related to histone deacetylase (HDAC). MeBib is an HDAC6 inhibitor derived from a benzimidazole scaffold. Many benzimidazole-containing compounds exhibit a wide range of pharmacological activity. In this study, we investigated whether HDAC6 inhibitor MeBib modulates the behavioral response in MA self-administered rats. Our results demonstrated that the number of active lever presses in MA self-administered rats was reduced by pretreatment with MeBib. In the hippocampus of rats, we also found MA administration promotes GluN2B, an NMDA receptor subunit, expression, which results in sequential activation of ERK/CREB/BDNF pathway, however, MeBib abrogated it. Collectively, we suggest that MeBib prevents the MA seeking response induced by MA administration and therefore, represents a potent candidate as an MA addiction inhibitor.Klotho is a putative aging suppressor gene that is primarily expressed in renal tubular epithelial cells. Its expression has been reported to protect against fibrosis in human chronic kidney disease. However, the roles of klotho in epithelial-mesenchymal transition (EMT) and renal fibrosis are yet to be elucidated. The present study aimed to investigate the putative roles of klotho in angiotensin (Ang) II-induced damage of renal tubular epithelial cells. NRK-52E rat cells were treated with various combinations of Ang II, the Ang-converting enzyme inhibitor fosinopril (Fos) and the Ang II receptor antagonist valsartan (Val). The levels of transforming growth factor (TGF)-β1, soluble klotho, α-smooth muscle actin (α-SMA) and E-cadherin in NRK-52E culture supernatants were measured using enzyme-linked immunosorbent assays. Furthermore, the mRNA and protein expression of TGF-β1, klotho, α-SMA and E-cadherin was detected using semiquantitative reverse transcription-polymerase chain reaction, immunocytochemistry and Western blot analysis. The results demonstrated that Ang II inhibited the expression of klotho and E-cadherin, while it upregulated the expression of TGF-β1 and α-SMA, in NRK52E cells. Fos and/or Val were revealed to enhance klotho and E-cadherin expression, and suppress the expression of TGF-β1 and α-SMA, compared with the Ang II-only group. Furthermore, a positive linear correlation was detected between the expression of klotho and E-cadherin, while negative linear correlations with klotho expression were detected for TGF-β1 and α-SMA expression. In conclusion, the expression of klotho was demonstrated to be enhanced following treatment with Fos and Val in Ang II-treated NRK-52E cells. The present results indicate that klotho may be involved in the inhibition of Ang II-induced EMT in renal tubular epithelial cells. Therefore, klotho may serve as a protective factor in renal tubulointerstitial fibrosis and aid the treatment of chronic kidney disease (CKD) patients using precision therapy.Background Avoidable hospitalizations (AHs) are defined as hospitalizations that could have been prevented through timely and effective services. AHs are, therefore, an indicator used to evaluate the access and effectiveness of primary health care services. Methods A retrospective time-series study spanning 8 years (2006-2013) was conducted to determine the relationship between AHs and gender, age, and access to primary health care physicians in rural areas in Tehran province, the capital of Iran. The total number of avoidable hospitalizations was 22,570; logistic regression was estimated for each year separately. Results Total hospitalizations and AHs increased during the study period, especially during the first 3 years of the study. AHs, as a percentage of total hospitalizations, did not change significantly throughout the study years. This value was 22.3% during the first year of study and varied between 17% and 19.6% from 2007 to 2013. No statistically significant relationship was seen between AH occurrence and access to a physician during the study years. Conclusion Increasing access to primary health care physicians cannot necessarily result in decreased AHs. Considering the factors influencing AHs while designing and implementing the family physicians program is important to achieve the expected results regarding the effectiveness of primary health care services.
