BACKGROUND The incidence of early-onset colorectal cancer (eoCRC) has been reported to increase, and patients with eoCRC seem to be diagnosed at more advanced stages compared to elderly patients. The aim of this study was to describe patient and disease characteristics, symptomatology and the incidence of eoCRC in a national cohort. MATERIALS AND METHODS 521 eoCRC patients (≤40 years old) diagnosed with histologically verified colorectal cancer (CRC) during the years 2001-2013 were identified in national databases and compared to more than 15,000 CRC patients aged 66-75 years. Age-adjusted incidence was calculated for eoCRC patients and various sub-analyses were performed. RESULTS More advanced stages were seen in eoCRC patients compared to elderly patients (stage II p less then 0.001, III p = 0.01 and IV p less then 0.01). Differences were statistically significant in colon cancer, but not in rectal cancer. A significant difference in sex distribution was seen between right and left-sided tumors in the eoCRC group. The age-adjusted incidence rate increased during the study period (1.60-2.55 per 100.000), and significant annual percent changes (APC) were seen in young females (APC = 4.73) and left-sided tumor localization (including rectal cancer) (APC = 4.54), respectively. CONCLUSION In this nationwide cohort of eoCRC patients, our results confirm that young patients are diagnosed at advanced stages, and that the incidence of eoCRC is increasing. Rivers are important routes for sea-bound microplastics. Thus, this study investigated the occurrences and distributions of microplastics and polychlorinated biphenyls (PCBs) in sediment samples from the Qiantang River (QR) and Hangzhou Bay (HZ) and analyzed the correlation between microplastics and PCBs. A total of 15 sampling sites were selected, including eight from the QR (i.e., four in the Tonglu area and four in the Fuyang area), two from the Andong salt marsh (ASM; located in a hydrodynamic turning point of the HZ), and five from HZ. The mean microplastic abundance was highest in the QR, followed by HZ and ASM, with 0.23 ± 0.06, 0.18 ± 0.05, and 0.15 ± 0.03 particles/g sediment, respectively. Cluster analysis demonstrated that fragments and fibers may have originated from domestic sewage inputs to the QR. Spatially, mean PCB concentrations from Tonglu, Fuyang, and HZ were 1.47 ± 0.10, 1.65 ± 0.10, and 1.65 ± 0.09 ng/g sediment, respectively, which were higher than that from the ASM (1.13 ± 0.09 ng/g sediment). The vertical distributions (0-5 cm, 5-10 cm, and 10-15 cm) of microplastics in the sediments at Tonglu and Fuyang decreased with increasing depth, which was opposite to the depth trend of PCB concentrations. Micro-Fourier transform infrared spectroscopy analysis suggested that polyethylene was typically the dominant polymer, accounting for 60 ± 0.08% of the total suspected plastic particles. Microbeads and films showed considerable correlations with both highly and lesser chlorinated PCBs. Overall, our findings highlight the need for routine monitoring of microplastics in China in addition to measures for controlling plastic pollution on a national scale. Further study should ascertain specific sources of microplastics and analyze their adsorption capacity to organic pollutants. BACKGROUND Stigma can exacerbate negative health outcomes in people living with HIV (PLWH). This longitudinal, cluster randomized controlled trial in rural Mpumalanga, South Africa, examined the interdependence of HIV-related stigma among pregnant couples living with HIV, and the potential impact of a lay health worker delivered intervention, Protect Your Family, on changes in stigma over time across couples, controlling for physical intimate partner violence (IPV), verbal IPV, gender, HIV knowledge, and months since HIV diagnosis. Using a form of the Actor-Partner Interdependence model, changes in stigma over time were also examined within each dyad of seroconcordant participants with HIV. METHOD Antenatal clinics were randomized to experimental or control conditions, and participants completed baseline antenatal and 12-month postpartum assessments. Both women and male partners participated in intervention sessions in gender concordant groups and couple or individual sessions. RESULTS Multilevel models (N = 1475) revealed stigma was related to condition and verbal intimate partner violence, but not time. Using an Actor-Partner Interdependence cross-lagged path model to examine within dyad changes in stigma for seroconcordant couples (n = 201), intervention condition participants' stigma levels were not interdependent over time. Women's 12-month stigma was related to their partners' stigma at baseline in the control condition, but not in the intervention condition. selleck compound DISCUSSION Compared to women in the control condition, postpartum stigma among women in the intervention condition was not related to their male partners' stigma, suggesting that women's perception of stigma became uncoupled from that of their partners. The intervention may have promoted female empowerment to shape their own beliefs and attitudes towards what it means to be infected with HIV, and express their own agency in responding to how others treat them and they treat themselves. In 129 Sv autosomal Alport mice, the strial capillary basement membranes (SCBMs) progressively thicken between 5 and 9 weeks of age resulting in a hypoxic microenvironment with metabolic stress and induction of pro-inflammatory cytokines and chemokines. These events occur concomitant with a drop in endocochlear potential and a susceptibility to noise-induced hearing loss under conditions that do not permanently affect age/strain-matched littermates. Here we aimed to gain an understanding of events that occur before the onset of SCBM thickening. Alport stria has normal thickness and shows levels of extracellular matrix (ECM) molecules in the SCBMs commensurate with wild-type mice. Hearing thresholds in the 3-week Alport mice do not differ from those of wild-type mice. We performed RNAseq analysis using RNA from stria vascularis isolated from 3-week Alport mice and wild type littermates. Data was processed using Ingenuity Pathway Analysis software and further distilled using manual procedures. RNAseq analysis revealed significant dysregulation of genes involved in cell adhesion, cell migration, formation of protrusions, and both actin and tubulin cytoskeletal dynamics.
