Dry eye disease (DED) is a complicated disorder that impacts ocular surface and tear-film stability. Inflammation has recently been reported as the core mechanism and main therapeutic target of DED. Although anti-inflammatory drugs have been developed, they still have limited efficacy and various side effects. Recent reports have suggested that kinase inhibitors are beneficial for relieving inflammation. Therefore, this study aimed to investigate the anti-inflammatory effects of LCB 03-0110, a multi-tyrosine kinase inhibitor, on representative cell-based models (HCE-2 and Th17 cells) of DED. While tacrolimus and tofacitinib, two different anti-inflammatory drugs that have entered clinical trials for DED treatment, did not induce any anti-inflammatory responses in HCE-2 cells, LCB 03-0110 significantly suppressed the phosphorylation of P38 and ERK and reduced the expression levels of IL-6 and IL-8 in HCE-2 cells treated with either LPS or poly(I:C). Moreover, LCB 03-0110 notably decreased the expression level of IL-17A in Th17 cells in a dose-dependent manner, whereas tofacitinib promoted IL-17A production at low concentrations but inhibited its expression at concentrations greater than 1 μM. In addition, LCB 03-0110 was found to be non-toxic to both HCE-2 and Th17 cells. In conclusion, these results suggest that LCB 03-0110 would be a promising drug candidate for the treatment of DED because of its advantages over tacrolimus and tofacitinib.

Objectives: The prevalence of posttraumatic stress disorder (PTSD) has increased, particularly among individuals who have recovered from coronavirus disease 2019 (COVID-19) infection. Health literacy is considered a “social vaccine” that helps people respond effectively to the pandemic. We aimed to investigate the association between long COVID-19 and PTSD, and to examine the modifying role of health literacy in this association. Methods: A cross-sectional study was conducted at 18 hospitals and health centers in Vietnamfrom December 2021 to October 2022. We recruited 4,463 individuals who had recovered from COVID-19 infection for at least 4 weeks. Participants provided information about their sociodemographics, clinical parameters, health-related behaviors, health literacy (usingthe 12-item short-form health literacy scale), long COVID-19 symptoms and PTSD (Impact Event Scale-Revised score of 33 or higher). Logistic regression models were used to examine associations and interactions. Results: Out of the study sample, 55.9% had long COVID-19 symptoms, and 49.6% had PTSD.Individuals with long COVID-19 symptoms had a higher likelihood of PTSD (odds ratio [OR], 1.86; 95% confidence interval [CI], 1.63–2.12; p < 0.001). Higher health literacy was associated with a lower likelihood of PTSD (OR, 0.98; 95% CI, 0.97–0.99; p = 0.001). Compared to those without long COVID-19 symptoms and the lowest health literacy score, those with long COVID-19 symptoms and a 1-point health literacy increment had a 3% lower likelihood of PTSD (OR, 0.97; 95% CI, 0.96–0.99; p = 0.001). Conclusion Health literacy was found to be a protective factor against PTSD and modified the negative impact of long COVID-19 symptoms on PTSD.

Backgrounds: Fecal occult blood testing (FOBT) is commonly used in colorectal cancer screening programs. Many studies have compared different FOBT methods, but the correlation between traditional red cell microscopy and FOBT remains unclear. Objectives: 1) To evaluate the rate of positive FOBT in patients with different disease groups; 2) To compare the sensitivity and specificity of red blood cells detection in fresh stool by microscopy technique and FOBT. Materials and methods: This was a cross-sectional study involving 120 patients from Hue University of Medicine and Pharmacy Hospital who requested a stool test from 4/2021 to 4/2022. Fresh stool samples were examined for the presence of red blood cells using traditional microscopy and FOBT technique. Results: The overall positivity rate of FOBT was 20%, and in the group of gastrointestinal diseases (n = 24), clinical anemia (n = 21), hepatobiliary diseases (n = 26) and other diseases (n = 49), it was 37.5%, 23.8%, 11.5% and 14.3%, respectively. In comparison with the FOBT technique, microscopic RBC detection had a sensitivity of 33.3% and a specificity of 100%. Conclusions: A high rate of fecal occult blood tests was observed in patients with gastrointestinal disorders. Microscopic erythrocyte detection has low sensitivity and many disadvantages compared to the rapid test. This rapid test should be widely used in clinical practice to aid in the diagnosis of gastrointestinal bleeding

Background: Hepatic stellate cells (HSCs) are the central players interacting with multiple cell types in liver fibrosis. The crosstalk between HSCs and macrophages has recently become clearer. Irisin, an exercise-responsive myokine, was known to have a potentially protective role in liver and renal fibrosis, especially in connection with stellate cells. This study investigated the effects of irisin on the interaction between HSCs and macrophages. Methods: Tamm-Horsfall protein-1 (THP-1) human monocytes were differentiated into macrophages, polarized into the inflammatory M1 phenotype with lipopolysaccharide. Lieming Xu-2 (LX-2) cells, human HSCs, were treated with conditioned media (CM) from M1 macrophages, with or without recombinant irisin. HSCs responses to CM from M1 macrophages were evaluated regarding activation, proliferation, wound healing, trans-well migration, contractility, and related signaling pathway. Results: CM from M1 macrophages significantly promoted HSC proliferation, wound healing, transwell migration, and contractility, but not activation of HSCs. Irisin co-treatment attenuated these responses of HSCs to CM. However, CM and irisin treatment did not induce any changes in HSC activation. Further, irisin co-treatment alleviated CM-induced increase of phopho-protein kinase B (pAKT), matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinases-1 (TIMP-1). Conclusion These findings suggested that irisin may play a protective role in the pathogenesis of liver fibrosis, especially when working in the crosstalk between HSCs and macrophages.

Background: Dipeptidyl peptidase-4 inhibitors (DPP-4Is) are used clinically as oral antidiabetic agents. Although DPP-4Is are known to ameliorate liver fibrosis, the protective mechanism of DPP-4Is in liver fibrosis remains obscure. In this study, gemigliptin was used to investigate the potential of DPP-4Is to alleviate the progression of liver fibrosis. Methods: To clarify the effects and mechanisms of gemigliptin, we conducted various experiments in LX-2 cells (immortalized human hepatic stellate cells [HSCs], the principal effectors of hepatic fibrogenesis), which were activated by succinate and exhibited elevated expression of α-smooth muscle actin, collagen type 1, and pro-inflammatory cytokines and increased cell proliferation. In vivo, we examined the effects and mechanisms of gemigliptin on a high-fat, high-cholesterol–induced mouse model of nonalcoholic steatohepatitis (NASH). Results: Gemigliptin decreased the expression of fibrogenesis markers and reduced the abnormal proliferation of HSCs. In addition, gemigliptin reduced the succinate-induced production of mitochondrial reactive oxygen species (ROS), intracellular ROS, and mitochondrial fission in HSCs. Furthermore, in the mouse model of NASH-induced liver fibrosis, gemigliptin alleviated both liver fibrosis and mitochondrial dysfunction. Conclusion Gemigliptin protected against HSC activation and liver fibrosis by alleviating mitochondrial dysfunction and ROS production, indicating its potential as a strategy for preventing the development of liver disease.

Several factors presumed to facilitate the transmission of Taenia spp. were reported in Vietnam. We conducted a cross-sectional study taking questionnaires from 1,185 participants, and collecting 1,151 sera and 1,036 stool samples in northern Vietnam. Sera were examined for circulating antigens of Taenia solium cysticerci using ELISA, stools for Taenia eggs by Kato-Katz smear, and copro-antigens by ELISA. Ag-ELISA revealed 4.6% antigen positivity, indicating infection with viable cysticerci. Taenia eggs were detected in 1.5% of participants. Copro-antigens were found in 2.8% of participants. Eating raw meat and/or vegetables was significantly associated with the presence of copro-antigen (OR=8.6, 95% CI: 1.16-63.9, P=0.01). Considering the high taeniasis prevalence and the associated threat, public health attention should be given to treat the tapeworm carriers in the projected areas.
