Fish Oil Derivatives in Hypertriglyceridemia: Mechanism and Cardiovascular Prevention: What Do Studies Say?

Hypertriglyceridemia is a type of dyslipidemia characterized by high triglyceride levels in the blood and increases the risk of cardiovascular disease. Conventional management includes antilipidemic medications such as statins, lowering LDL and triglyceride levels as well as raising HDL levels. However, the treatment may be stratified using omega-3 fatty acid supplements such as eicosatetraenoic acid (EPA) and docosahexaenoic acid (DHA), aka fish oil derivatives. Studies have shown that fish oil supplements reduce the risk of cardiovascular diseases; however, the underlying mechanism and the extent of reduction in CVD need more clarification. Our paper aims to review the clinical trials and observational studies in the current literature, investigating the use of fish oil and its benefits on the cardiovascular system as well as the proposed underlying mechanism.

"It's Not Good to Be Sick and Have the Child": Perspectives on Pregnancy After HIV-Positive Diagnosis Among Women in Western Jamaica.

Purpose: To identify factors associated with reproductive decision-making for women living with HIV in Western Jamaica, to assess their confidence in anti-retroviral therapy to reduce the chances of mother to child transmission of HIV, and to better understand the experience of stigmatization surrounding becoming pregnant after HIV diagnosis. Participants and Methods: Two focus groups were conducted among women living with HIV in the four parishes of Western Jamaica in 2011. A trained moderator conducted the focus groups along with two student notetakers. Qualitative coding and content analysis were used to identify common themes and exemplary quotations characterizing those themes. Results: Participants agree that adherence to antiretroviral therapy as prescribed by a physician facilitates better health and longevity; however, they were conflicted on the efficacy of the therapy to prevent mother to child transmission of the virus. Participants report that becoming pregnant after HIV diagnosis continues to be highly stigmatized. Among participants, fear of MTCT and concern that their children will be mistreated are the primary drivers of reproductive decision-making. Conclusion: Despite advances in HIV treatment and assisted technologies to prevent MTCT, participants show skepticism that ARV medication is effective at preventing MTCT. Stigma and discriminatory behavior by community members and health-care professionals continue to shape reproductive decision-making for the women who participated in this study. More informed counseling that includes education on recent advancements in HIV treatment and its efficacy at preventing MTCT should be more widely available to pregnant women. To reduce stigma and discriminatory behavior, this education should extend to the larger community.

Anti-Inflammatory Effects of Conditioned Medium of Periodontal Ligament-Derived Stem Cells on Chondrocytes, Synoviocytes, and Meniscus Cells.

Osteoarthritis (OA) is the most common type of arthritis, afflicting millions of people in the world. Elevation of inflammatory mediators and enzymatic matrix destruction is often associated with OA. Therefore, the objective of this study was to investigate the effects of conditioned medium from periodontal ligament-derived stem cells (PDLSCs) on inflammatory and catabolic gene expressions of chondrocytes, synoviocytes, and meniscus cells under in vitro inflammatory condition. Stem cells were isolated from human periodontal ligaments. Conditioned medium was collected and concentrated 20 × . Chondrocytes, synoviocytes, and meniscus cells were isolated from pig knees and divided into four experimental groups: serum-free media, serum-free media+interleukin-1ß (IL-1ß) (10 ng/mL), conditioned media (CM), and CM+IL-1ß. Protein content and extracellular vesicle (EV) miRNAs of CM were analyzed by liquid chromatography-tandem mass spectrometry and RNA sequencing, respectively. It was found that the IL-1ß treatment upregulated the expression of IL-1ß, tumor necrosis factor-α (TNF-α), MMP-13, and ADAMTS-4 genes in the three cell types, whereas PDLSC-conditioned medium prevented the upregulation of gene expression by IL-1ß in all three cell types. This study also found that there was consistency in anti-inflammatory effects of PDLSC CM across donors and cell subcultures, while PDLSCs released several anti-inflammatory factors and EV miRNAs at high levels. OA has been suggested as an inflammatory disease in which all intrasynovial tissues are involved. PDLSC-conditioned medium is a cocktail of trophic factors and EV miRNAs that could mediate different inflammatory processes in various tissues in the joint. Introducing PDLSC-conditioned medium to osteoarthritic joints could be a potential treatment to prevent OA progression by inhibiting inflammation.
