How is gut microbiome of patients with familial adenomatous polyposis different from healthy people?
The gut microbiome has been increasingly suggested as an underlying cause of various human diseases. In this study, we hypothesized that the gut microbiomes of patients with familial adenomatous polyposis (FAP) are different from those of healthy people and attempted to identify the associations between gut microbiome characteristics and FAP. We collected fecal samples from patients with FAP and healthy volunteers and evaluated the diversity, composition, and distribution of the gut microbiome between the 2 groups via 16S rRNA-based taxonomic profiling of the fecal samples. ⋯ We also found 7 specific abundant strains in fecal samples of patients with FAP. Patients with FAP had different Firmicutes/Bacteroidetes ratios and Proteobacteria abundance compared to healthy people and showed the presence of specific bacteria. These findings suggest a promising role of the gut microbiome in patients with FAP, although further studies are needed.

The ST segment is component of the QRS-T complex located between the QRS and the T wave. ST segment changes during tachycardia with narrow QRS mainly takes the form of ST segment depression. This phenomenon is often observed in young healthy people for whom an ischemic background is unlikely. ⋯ In patients with atrioventricular nodal reentrant tachycardia, there is a significant ST-segment depression during tachycardia episodes and the degree of this change is related to tachycardia cycle length. The most probable explanation of the ST-segment depression is the overlap of the QRS complex on the preceded T wave. This phenomenon is also influenced by some intrinsic properties of the individual electrocardiogram. It is possible to rule out ischemic origin of the presented ST segment change.

To report the first case of lens dislocation and secondary acute angle-closure glaucoma (AACG) following use of a percussion massage gun (PMG) around the eye. ⋯ Caregivers, sports professionals and the general public should be aware of the dangers of PMGs and the need to use them appropriately and safely, for example during self-massage and rehabilitation therapy. In particular, we recommend not using PMGs above the neck, which should be clearly indicated in instruction manuals.

Hypertension is a multifactorial disease that partially caused by genetic factors, including variation in genes related to lipid metabolism. ACAT1 gene is implicated in lipid metabolism for its encoding product, the enzyme acetyl-CoA acetyltransferase 1, catalyzing the synthesis of cholesteryl ester from cholesterol and playing an important role in the metabolism of cholesterol. Until now, there's little study on the relationship between ACAT1 variants and hypertension. ⋯ AC/CC genotypes of rs1044925 were associated with an increased risk of hypertension (AC/CC vs AA: adjusted odds ratio = 1.723, 95% confidence interval = 1.160-2.559, P = .007). However, the AC/CC genotypes showed no relationship with serum lipid levels. The results suggest that the C carriers of ACAT1 rs1044925 might increase the risk of hypertension in Tongdao Dong population, and the underlying mechanism needs to be further studied.

Forkhead transcription factor O1 (FOXO1) methylation is associated with inflammation. Diabetic kidney disease (DKD) is characterized with increased inflammatory markers such as uric acid, hemogram indices, C-reactive protein derived markers, omentin and neuregulin. This study aimed to investigate the effect of DNA methylation in FOXO1 gene promoter, blood glucose and lipids in the process of type 2 DKD. ⋯ The levels of low-density lipoprotein were statistically lower in preliminary diabetes mellitus and DKD groups than control group (all P value < .02). Along with the progress of DKD, a down trend was observed in the total methylation rate of FOXO1 gene (P = .025), which contains 5 CpG sites (1021, +1193) in the promoter. Hypomethylation in the promoter of FOXO1 gene, hyperglycemia and low level of serum lipid might be associated with the pathogenesis of type 2 DKD.
