The association between serum uric acid levels and ischemic stroke in essential hypertension patients.
Objectives: The association between serum uric acid (SUA) and ischemic stroke is still inconsistent across population. This study aimed to examine the association between SUA and ischemic stroke in essential hypertension patients. Methods: This retrospective study recruited participants from September 2011 to December 2012, in the Liao-bu community, Guangdong Province, China, and followed them until 31 December 2016. ⋯ Gender subgroup analysis showed SUA was an independent risk of ischemic stroke in female (HR = 1.35, 95%CI: 1.11, 1.81, P = 0.002) and male (HR = 1.53, 95%CI: 1.14, 1.92, P < 0.001). ROC curve demonstrated that SUA yielded an AUC of 0.7476 (95%CI: 0.7098, 0.7855, P < 0.001) for predictive of ischemic stroke. Conclusions: SUA was an independent risk factor for ischemic stroke, and also have a good predictive value ischemic stroke among hypertensive patients in Chinese community.

Helicobacter pylori antibiotic resistance and correlation with cagA motifs and homB gene.
Objectives:Helicobacter pylori (H. pylori) infection caused by antibiotic-resistant strains represents a major public health threat that aggressively promotes gastric cancer progression. Antibiotic resistance evaluation is immensely important to counteract its emergence. Here we merely determine the prevalence of antibiotic resistance in H. pylori isolates and its correlation with cagA motifs and the homB gene. ⋯ A significant relationship was observed between amoxicillin resistant rate with ABC-homB (p= 0.0006). Conclusion: The Resistance rate to selected antibiotics in Shiraz is higher than years ago. The presence of cagA-homB+ is associated with antibiotic resistance and also homB can be used as a marker to antibiotic resistance status prediction in H. pylori isolated in this area.

The impact of concurrent Hashimoto thyroiditis on thyroid nodule cytopathology assessed by ultrasound-guided fine-needle aspiration cytology.
Objective: Thyroid nodules are highly prevalent and a common clinical problem worldwide. How to identify the nature of a nodule is a major concern of clinicians. Fine needle aspiration cytology (FNAC) has an established role and is well-utilized in nodule management. ⋯ No statistical difference was found either in the rate of a nondiagnostic cytology results or in the rate of indeterminate cytology results between patients with positive anti-thyroid autoantibodies and patients with negative test for anti-thyroid autoantibodies (P > 0.05). The same was true between patients with histopathologically confirmed HT and HT-negative ones (P > 0.05). Conclusions: The presence of concurrent HT, whether clinically implied with positive anti-thyroid autoantibodies or pathologically confirmed, is unlikely to predispose an FNAC diagnosis of thyroid nodules to be non-diagnostic or indeterminate.

Characterizing the gut microbiota in patients with chronic kidney disease.
Objectives: Emerging evidence suggests that gut microbiota dysbiosis plays a critical role in chronic kidney disease (CKD). However, the relationship between altered gut microbiome profiles and disease severity remains unclear. In this study, we sought to characterize the gut microbiota in CKD patients compared to healthy controls, and to explore potential relationships between gut microbiota composition and disease severity. ⋯ Functional analysis also revealed that fatty acid and inositol phosphate metabolism were enriched in the CKD group, while aminoacyl-tRNA biosynthesis, oxidative phosphorylation, phenylalanine, tyrosine, and tryptophan biosynthesis, thiamine metabolism, pantothenate, and CoA biosynthesis, as well as valine, leucine, and isoleucine biosynthesis were enriched in healthy controls. Conclusion: Gut microbiota composition and function are associated with CKD severity. And, specific gut microbes are potentially helpful for CKD early diagnosis and prognosis monitoring.
