HBV relapse rates in patients who discontinue tenofovir disoproxil fumarate with or without switching to tenofovir alafenamide.

Background/aims: The incidence and relapse pattern in patients stopping tenofovir alafenamide (TAF), a prodrug of tenofovir which is more concentrated in hepatocytes, is unknown.

Methods: HBeAg-negative CHB patients stopping tenofovir disoproxil fumarate (TDF) (off-TDF) or who had switched to TAF more than 3 months before discontinuation (off-TAF) were recruited. The propensity score-matching method (PSM) was used, creating a ratio of 1:3 between the off-TAF versus the off-TDF groups to adjust for associated factors.

Novel plasma metabolite markers of attention-deficit/hyperactivity disorder identified using high-performance chemical isotope labelling-based liquid chromatography-mass spectrometry.

Objectives: Metabolites are the intermediate and final products of biological processes and ultimately reflect the responses of these processes to genetic regulation and environmental perturbations, including those involved in attention deficit/hyperactivity disorder (ADHD).

Methods: We identified a quantitative profile of plasma metabolites in 58 ADHD patients (mean age 9.0 years, 77.

The effect of pilocarpine on dental caries in patients with primary Sjögren's syndrome: a database prospective cohort study.

Background: Primary Sjögren's syndrome (pSS) is associated with dental caries. Pilocarpine, a salivary stimulant, can improve the amount and flow rate of saliva in patients with pSS. This study aimed to assess whether the risk of dental caries decreases with the use of pilocarpine in patients with pSS.

Peripheral Brain-Derived Neurotrophic Factor and Contactin-1 Levels in Patients with Attention-Deficit/Hyperactivity Disorder.

Brain-derived neurotrophic factor (BDNF) facilitates neuronal growth and plasticity, and is crucial for learning and memory. Contactin-1 (CNTN1) is a member of the subfamily of neural immunoglobulin and is involved in the formation of axon connections in the developing nervous system. This cross-sectional study investigates whether BDNF and CNTN1 affect susceptibility to attention deficit/hyperactivity disorder (ADHD).

Mitochondrial-associated protein biomarkers in patients with attention-deficit/hyperactivity disorder.

This study aimed to determine the role of mitochondria-associated proteins (HtrA2, α-synuclein, and Park7) in attention deficit/hyperactivity disorder (ADHD). A total of 125 patients with ADHD (77.6% were males) and 66 healthy controls (66.

Real-world safety and efficacy of paritaprevir/ritonavir/ombitasvir plus dasabuvir ± ribavirin in patients with hepatitis C virus genotype 1 and advanced hepatic fibrosis or compensated cirrhosis: a multicenter pooled analysis.

Paritaprevir/ritonavir, ombitasvir, and dasabuvir (PrOD) with or without ribavirin shows favorable results in hepatitis C virus genotype 1 (HCV-1) patients in terms of safety and efficacy, but real-world data remain limited for those with advanced hepatic fibrosis (fibrosis 3, F3) or compensated cirrhosis (F4). A total of 941 patients treated in four hospitals (the Keelung, the Linkuo, the Chiayi and the Kaohsiung Chang Gung Memorial Hospital) through a nationwide government-funded program in Taiwan were enrolled. Patients with HCV and advanced hepatic fibrosis or compensated cirrhosis received 12 weeks of PrOD in HCV-1b and 12 or 24 weeks of PrOD plus ribavirin therapy in HCV-1a without or with cirrhosis.

A split-face study: comparison of picosecond alexandrite laser and Q-switched Nd:YAG laser in the treatment of melasma in Asians.

To evaluate efficacy and safety of picosecond 755 nm alexandrite laser as compared to 1064 nm QS-Nd:YAG laser for melasma treatment in Asians. Twelve patients received 4 sessions of treatments at 1-month interval in a split-face manner. The right side of each patient's face received 755 nm picosecond laser, and the other side received 1064 nm QS-Nd:YAG laser.

Increased serum levels of cysteine in patients with schizophrenia: A potential marker of cognitive function preservation.

Background: Oxidative stress has been implicated in the psychopathology of schizophrenia. Cysteine, a semi-essential amino acid, is the precursor of the antioxidant glutathione. The aim of this study was to investigate the differences in serum levels of cysteine between patients with schizophrenia and healthy controls.

β-hydroxybutyrate, pyruvate and metabolic profiles in patients with schizophrenia: A case control study.

The disturbances of β-hydroxybutyrate (β-HB) and pyruvate are linked with impaired brain energy utilization which involves in the psychopathology of schizophrenia. This study investigates the difference in levels of β-HB and pyruvate between patients with schizophrenia and healthy controls, and explores their relationship with metabolic profiles and disease characteristics. We recruited 54 physically-health schizophrenic patients and 54 age- and gender-matched healthy control subjects.
