Cardiovascular complications are a well-documented limitation of cancer chemotherapy. Cisplatin-induced cardiotoxicity threatens the health and life of patients, and limits the application of cisplatin. Oxidative stress is the main mechanism underlying cisplatin-induced cardiac toxicity. Luteolin (Lut) has been reported to possess cardioprotective properties by activating nuclear factor-E2-related factor 2 (Nrf2) -mediated antioxidant response. However, the effect of Lut on cisplatin-induced cardiac damage remains unclear. In this study, we revealed that Lut exerted a protective effect against cisplatin-induced cardiac dysfunction and injury in vivo. In HL-1 cells, Lut was observed to dramatically reduce cisplatin-induced apoptosis and oxidative stress by modulating the Kelch-like epichlorohydrin-associated protein 1 (Keap1)/Nrf2 pathway. Altogether, these findings suggested that Lut showed promise in attenuating cisplatin-induced cardiac injury and might be considered a protective drug candidate for chemotherapy-associated cardiovascular complications.Older adults living with HIV (OALH) undergo challenges such as comorbidities, social isolation, and "double stigma" associated with their HIV and aging statuses. Simultaneously, research has shown that experiences of childhood sexual abuse (CSA) continue to impact the quality of life across the lifespan and may pose unique hardships for older adults. Despite the high prevalence of trauma among people living with HIV, research examining the psychosocial challenges of OALH with a CSA history is scant. To address this gap in the literature, this study aimed to explore psychosocial challenges among OALH who are CSA survivors using a qualitative approach. Twenty-four in-depth, semi-structured interviews were completed with OALH (age 50 years and older) who reported histories of CSA. Multiple coders and an inductive coding process were employed for data analysis. Four main themes regarding psychosocial challenges emerged from the analysis (1) depression and suicidal ideation, (2) fear and anxiety, (3) social support issues, and (4) memory issues. The authors discuss the implications of these findings and the importance of trauma-informed treatment for these individuals.Natural value-added compounds produced from biological sources have attained immense significance in medicinal, food, flavourings, and agrochemical industries. Further, biotransformation is a powerful tool used to produce value-added compounds cost-effectively and selectively. In the present study, biotransformation of eugenol using an endophytic fungus Daldinia sp. IIIMF4010 isolated from the fresh leaves of the plant Rosmarinus officinalis leads to the production of two known value-added compounds. The biotransformation reaction of eugenol (50 mM) resulted in the production of eugenol-β-D-glucopyranoside (6.2%) and vanillin (21.8%). These biotransformed products were further characterized by liquid chromatography-mass spectroscopy (LC-MS) and nuclear magnetic resonance (NMR).The progression of gestational diabetes mellitus (GDM) to metabolic syndrome (MetS) is associated with systemic inflammation. The aim of this study was to compare the levels of inflammatory markers in former GDM patients with and without MetS. Medical records were screened retrospectively for patients who were diagnosed with GDM 10 (±2) years ago. Former GDM patients were invited to the hospital for an assessment of their current health status. Of 52 women with former GDM, 27 (52%) had MetS. C-reactive protein (CRP), interleukin-6 and plasminogen activator inhibitor-1 (PAI-1) levels were significantly higher in the MetS group while adiponectin was significantly lower (p  less then  .001, p = .037, p = .002 and p = .013, respectively). There was no significant difference in plasma levels of visfatin and tumour necrosis factor-α. Interleukin-6, CRP, PAI-1 and adiponectin may be used as biomarkers to detect MetS in the pre-clinical phase. With timely diagnosis, early interventions can be implemented. IMPACT STATEMENTWhat is already known on this subject? The progression of 'gestational diabetes mellitus' to 'metabolic syndrome' is associated with systemic inflammation. Up to half of cases with former gestational diabetes mellitus (GDM) eventually progress to metabolic syndrome (MetS).What do the results of this study add? Interleukin-6, C-reactive protein, plasminogen activator inhibitor-1 and adiponectin may be used as biomarkers to detect MetS in the pre-clinical phase.What are the implications of these findings from clinical practice and/or further research? The progression of GDM to MetS is associated with systemic inflammation. Potential therapies should therefore target this inflammatory state. Interleukin-6, C-reactive protein, plasminogen activator inhibitor-1 and adiponectin may be used as biomarkers to detect MetS in the pre-clinical phase. With timely diagnosis, early interventions and lifestyle changes can be implemented to prevent morbidity and mortality associated with full-blown MetS.Community-based delivery of oral HIV self-testing (HIVST) may expand access to testing among adolescents and young adults (AYA). Eliciting youth perspectives can help to optimize these services. We conducted nine focus group discussions (FGDs) with HIV negative AYA aged 15-24 who had completed oral HIVST following community-based distribution through homes, pharmacies, and bars. FGDs were stratified by distribution point and age (15-17, 18-24). Participants valued HIVST because it promoted greater autonomy and convenience compared to traditional clinic-based testing. AYA noted how HIVST could encourage positive behavior change, including using condoms to remain HIV negative. Participants recommended that future testing strategies include individualized, ongoing support during and after testing. Support examples included access to trained peer educators, multiple community-based distribution points, and post-test support via phones and websites. Multiple distribution points and trained peer educators' involvement in all steps of distribution, testing, and follow-up can enhance future community-based HIVST programs.Adolescents and young adults ("youth") account for one-fifth of new HIV diagnoses in the U.S. HIV pre-exposure prophylaxis (PrEP), which became FDA approved in adolescents in May 2018, is highly effective at preventing HIV infection though there are limited data for PrEP initiation in youth. We aimed to quantify PrEP initiation and identify factors associated with PrEP initiation among youth at risk for HIV. Proteases inhibitor We conducted a retrospective cohort study of youth aged 13-26 years who had an indication for PrEP between 1 January 2015, and 31 December 2018. We used data on commercially insured US individuals from the IBM MarketScan Commercial Database. We compared factors among youth who did and did not receive PrEP. We developed a multivariable logistic regression model to identify the association of all study covariates with receipt of PrEP. Among potentially PrEP eligible youth, only 2171 (1.6%) received a PrEP prescription in the year following their PrEP eligible claim. In multivariable models, youth who received PrEP were more likely to be older (adjusted odd ratio [aOR] for 18-20 year olds = 5.11; 95% CI = 3.35-7.77; aOR for 21-26 year olds = 16.90; 95% CI = 11.0-24.7), male (aOR = 92.42; 95% CI = 68.24-125), have sexual activity with elevated risk (aOR = 7.47; 95% CI = 6.50-8.60), or be diagnosed with gonorrhea or syphilis than youth who did not receive PrEP. Our findings highlight an opportunity to improve HIV prevention early in the life course.Kaempferol and its derivatives are naturally occurring phytochemicals with promising bioactivities. This flavonol can reduce the lipid oxidation in the human body, prevent the organs and cell structure from deterioration and protect their functional integrity. This review has extensively highlighted the antioxidant, antimicrobial, anticancer, neuroprotective, and hepatoprotective activity of kaempferol. However, poor water solubility and low bioavailability of kaempferol greatly limit its applications. The utilization of advanced delivery systems can improve its stability, efficacy, and bioavailability. This is the first review that aimed to comprehensively collate some of the vital information published on biosynthesis, mechanism of action, bioactivities, bioavailability, and toxicological potential of kaempferol. Besides, it provides insights into the future direction on the improvement of bioavailability of kaempferol for wide applications.Various studies, especially in recent years, have shown that quercetin has beneficial therapeutic effects in various human diseases, including diabetes. Quercetin has significant anti-diabetic effects and may be helpful in lowering blood sugar and increasing insulin sensitivity. Quercetin appears to affect many factors and signaling pathways involved in insulin resistance and the pathogenesis of type 2 of diabetes. TNFα, NFKB, AMPK, AKT, and NRF2 are among the factors that are affected by quercetin. In addition, quercetin can be effective in preventing and ameliorating the diabetic complications, including diabetic nephropathy, cardiovascular complications, neuropathy, delayed wound healing, and retinopathy, and affects the key mechanisms involved in the pathogenesis of these complications. These positive effects of quercetin may be related to its anti-inflammatory and anti-oxidant properties. In this article, after a brief review of the pathogenesis of insulin resistance and type 2 diabetes, we will review the latest findings on the anti-diabetic effects of quercetin with a molecular perspective. Then we will review the effects of quercetin on the key mechanisms of pathogenesis of diabetes complications including nephropathy, cardiovascular complications, neuropathy, delayed wound healing, and retinopathy. Finally, clinical trials investigating the effect of quercetin on diabetes and diabetes complications will be reviewed.BEROSE is a single-center observational study, which aimed to determine the proportion of women with breast cancer who received information on sexual health from health professionals throughout their whole care pathway. A total of 318 women with all stages of breast cancer (30% metastatic) and at different time interval from diagnosis (up to 7 years) participated to the survey. Sixty-five percent of women reported that they had not received any information about sexual health over the whole care. Increased awareness among the healthcare professionals and particularly the oncology community is needed to discuss sexual health in women with breast cancer.In most mammalian species, the testis descends from the abdomen into the scrotum during fetal or neonatal life. The failure of testicular descent, a pathological condition known as cryptorchidism, has long been the subject of scientific interest in a wide range of fields, including medicine, developmental biology, and evolutionary biology. In this study, we analyzed global gene expression changes associated with experimental cryptorchidism in mice by using RNA-seq. A total of 453 differentially expressed genes were identified, of which 236 genes were upregulated, and 217 genes were downregulated. Gene ontology, pathway, and gene network analysis highlighted the activation of inflammatory response in experimental cryptorchidism. By examining the promoter regions of differentially expressed genes, we identified 12 causal transcription factors. In addition, we also induced experimental cryptorchidism in two cynomolgus monkeys and performed RNA-seq. A cross-species comparison was performed at the gene expression level.
