Real‐life impact of tenofovir disoproxil fumarate and entecavir therapy on lipid profile, glucose and uric acid in chronic hepatitis B patients

alexandrossfakianakis shared this article with you from Inoreader Real‐life impact of tenofovir disoproxil fumarate and entecavir therapy on lipid profile, glucose and uric acid in chronic hepatitis B patients via Journal of Medical Virology Abstract Background & Aims The impact of long-term nucleos(t)ide analogs treatment on host metabolism is a concern. Hence, we conducted this study to compare the effect of entecavir (ETV) and tenofovir disoproxil fumarate (TDF) on metabolic parameters among CHB patients. Methods In this real-life retrospective study, 2,030 CHB outpatients treated with ETV or TDF at Nanfang Hospital, China, were included. For treatment-naïve patients, pretreatment and semiannual metabolic parameters were collected. For treatment-experienced patients, metabolic parameters were collected at the first visit. Propensity score matching (PSM) was used to balance the effects of potential confounding factors. Results Among 122 treatment-naïve patients and 1908 treatment-experienced patients, ETV-treated patients were older with a higher percentage of metabolic syndrome. After PSM, the characteristics were comparable between the two groups. For treatment-naïve patients, fou r lipid parameters, including total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein and triglyceride levels showed a decreasing trend during the 42-month TDF treatment, while they remained relatively stable or increased during ETV treatment. At month 30, the levels of TC and LDL among TDF-treated patients were significantly lower than those among ETV-treated patients (TC: 4.7 vs. 3.9 mmol/L, p=0.004; LDL: 3.0 vs. 2.4 mmol/L, p=0.009). For treatment-experienced patients, we also observed lower levels of lipid parameters in patients with different durations of TDF treatment. The levels of glucose and uric acid were similar among ETV- and TDF-treated patients. Conclusion TDF has a lipid-lowering effect in CHB patients, which provides a basis for the selection of antiviral drugs for aging CHB patients. This article is protected by copyright.

Longitudinal follow‐up of HPV16 sequence after cervical infection: low intra‐host variation and no correlation with clinical evolution

alexandrossfakianakis shared this article with you from Inoreader Longitudinal follow‐up of HPV16 sequence after cervical infection: low intra‐host variation and no correlation with clinical evolution via Journal of Medical Virology ABSTRACT Human papillomavirus (HPV) 16 exhibits different variants that may differ in their carcinogenic risk. In order to identify some high-risk variants, we sequenced and compared HPV16 whole genomes obtained from a longitudinal cohort of 34 HPV16-infected women who had either spontaneously cleared their infection (clearance group or "C"), or developed cervical high-grade lesions following a viral persistence (group persistence or "P"). Phylogenetic analysis of paired samples obtained at the beginning (C0 or P0) and at the end (C2 or P2) of the follow-up (median intervals between C0-C2 and between P0-P2 were 16 and 36.5 months, respectively) revealed a low genetic variability within the host compared to the genetic inter-host diversity. By comparing our HPV16 sequences to a reference sequence, we observed 301 different substitutions, more often transitions (60.9%) than transversions (39.1%), that occurred throughout the viral genome, but with a low frequen cy in E6 and E7 oncogenes (10 and 9 substitutions), suggesting a high conservation of these genes. Deletions and insertions were mostly observed in intergenic regions of the virus. The only significant substitution found between the subgroups C2 and P2 was observed in the L2 gene (L330F), with an unclear biological relevance. Our results suggest a low longitudinal intra-host evolution of HPV16 sequences and no correlation between genetic variations and clinical evolution. This article is protected by copyright.

Deriving prognostic significance from a molecular subtype model of laryngeal carcinoma

alexandrossfakianakis shared this article with you from Inoreader Deriving prognostic significance from a molecular subtype model of laryngeal carcinoma via Head & Neck Abstract Background This study explored whether laryngeal carcinoma could be divided into different subtypes based on molecular differences using a molecular subtype-prediction model. Methods We extracted data from the Cancer Genome Atlas and Gene Expression Omnibus databases and then performed unsupervised cluster analysis to identify discrete molecular subtypes of laryngeal carcinoma. Significance analysis of microarrays was performed to detect differentially expressed genes for each subtype, and gene set enrichment analysis and the GenCliP3 software were used to label gene functions and identify key pathways. Results We categorized 126 patients into C1 and C2 molecular subtypes associated with pathologic grade. The C2 subtype appeared more aggressive, with a worse prognosis. The most significant enrichment pathway of the C2 subtype was the Hedgehog pathway, and GLI1 was a core gene. Conclusions Laryngeal carcinoma can be divided into two subtypes based on differences in molecular expression, which could identify key molecules associated with prognosis. View on Web

Immediate curative effects of exercise therapy in patients with myalgia of the masticatory muscles

alexandrossfakianakis shared this article with you from Inoreader Immediate curative effects of exercise therapy in patients with myalgia of the masticatory muscles via Journal of Oral Rehabilitation Abstract Background Exercise therapy is occasionally considered as an initial treatment for temporomandibular disorders. However, pain can be exacerbated during exercise therapy. Objective To investigate the immediate curative effects of exercise therapy in patients with masticatory muscle myalgia. Methods Fifty-nine patients with masticatory muscle myalgia were included. Therapists performed exercise therapy (stretched the painful masseter and/or cervical muscles along the direction of muscle contraction) in 10 rounds of traction, each lasting 10 seconds. The patient's pain-free maximum mouth opening distance and degree of pain (VAS value) before and immediately after exercise therapy were compared using the Wilcoxon signed rank test. Mann-Whitney U test was used for the subgroup comparisons. Results Mouth opening increased from 41 (IQR 38–43) to 46 (IQR 43–48) mm, and pain alleviation from 48 (IQR 31–56) to 21 (IQR 10–56) immediately following exercise therapy (p < 0.001 for both). None of the patients experienced pain exacerbation or reduction in mouth opening post exercise. No difference in mouth opening distance changes according to sex, painful side, painful site, and therapist were observed (p > 0.05 for all). Pain reduction was greater in patients with unilateral pain (26, IQR 12–39) than those with bilateral (13, IQR 5–25) (p = 0.019). There were no differences in the change in the degree of pain according to sex, painful site, and therapist (p > 0.05 for all). Conclusion Exercise therapy immediately enlarged the mouth opening distance and reduced myalgia; therefore, it could be helpful in managing masticatory muscle myalgia. View on Web
