    Pancreatic cancer is a disease associated with a poor overall survival. Advances in surgical techniques have helped improve outcomes of patients who are amenable to surgical resection. Sadly, surgery is amenable in only a small percentage of patients with the disease. Thus, there is a need to direct efforts at reducing the overall risk of pancreatic cancer or facilitating its early detection. The current review focused on collating all the literature published to date on pancreatic cancer in Australia with an aim to identify opportunities for intervention (at a state or national level) that are specific to Australia so as to help improve the outcome of patients with pancreatic cancer.Long noncoding RNAs (lncRNAs) dysregulation leads to malignant progression of lung cancer. Our study profiled differentially expressed lncRNA and mRNA in tumor and normal tissues of lung adenocarcinoma (LUAD). Further, analysis of the gene expression profiles of LUAD tissues (n = 533) and normal tissues (n = 59) from The Cancer Genome Atlas (TCGA). AZD3514 nmr A total of 138 lncRNAs were differentially expressed between LUAD tissues and normal tissues (false discovery rate q less then 0.05, fold change (FC) ≥ 2), a number of which are key regulators of multiple cancer and biological processes in humans. For example, lncRNA A2M-AS1 displayed the highest correlation with the co-expressed mRNAs, indicating that it might play a key role in regulating differential gene expression in LUAD. The data from the current study of the comprehensive lncRNA expression profile in LUAD tissues provided useful information to guide the identification of potential LUAD biomarkers.Oceanic oxygen minimum zones (OMZs) play a pivotal role in biogeochemical cycles due to extensive microbial activity. How OMZ microbial communities assemble and respond to environmental variation is therefore essential to understanding OMZ functioning and ocean biogeochemistry. Sampling along depth profiles at five stations in the eastern tropical North Pacific Ocean (ETNP), we captured systematic variations in dissolved oxygen (DO) and associated variables (nitrite, chlorophyll, and ammonium) with depth and between stations. We quantitatively analysed relationships between oceanographic gradients and microbial community assembly and activity based on paired 16S rDNA and 16S rRNA sequencing. Overall microbial community composition and diversity were strongly related to regional variations in density, DO, and other variables (regression and redundancy analysis r2 = 0.68-0.82), displaying predictable patterns with depth and between stations. Although similar factors influenced the active community, diversity was substantially lower within the OMZ. We also identified multiple active microbiological networks that tracked specific gradients or features – particularly subsurface ammonium and nitrite maxima. Our findings indicate that overall microbial community assembly is consistently shaped by hydrography and biogeochemistry, while active segments of the community form discrete networks inhabiting distinct portions of the water column, and that both are tightly tuned to environmental conditions in the ETNP.Tumour microenvironment of brain lower grade glioma (LGG) consists of non-tumour cells including stromal cells and immune cells mainly. These non-tumour cells dilute the purity of LGG and play pivotal roles in tumour growth and development, thereby affecting patient prognosis. Tumour purity is also associated with molecular subtypes of LGG. In this study, we discovered the most relevant module to purity by weighted gene co-expression network analysis (WGCNA) and afterwards performed consensus network analysis and survival analysis to filter 61 significant genes related to both purity and prognosis. In turn, we built a simplified model based on the calculation of purity score, and consensus measurement of purity estimation (CPE), with a satisfactory predictive performance by random forest regression. HLA-E, MSN, GNG-5, MYL12A, ITGB4, PDPN, AGTRAP, S100A4, PLSCR1, VAMP5 were selected as the most relevant genes correlating to both purity and prognosis. The risk score model based on the 10 genes could moderately predict patients’ overall survival. These 10 genes, respectively, were positively correlated positively to immunosuppressive cells like macrophage M2, but negatively correlated to patient prognosis, which may explain partially the poor prognosis with low-purity group.

    For middle-aged persons with type 1 diabetes, diabetes management is essential due to the natural effects of middle age. However, studies investigating how such individuals manage their diabetes are lacking. This study aimed to explore diabetes management experiences of middle-aged individuals with type 1 diabetes.

    Data were collected through in-depth interviews with six middle-aged persons with diabetes. An interpretative phenomenological analysis was used for the analysis of the data.

    The following four themes emerged “familiarity with but no control over type 1 diabetes”, “embodiment of one’s unique management of type 1 diabetes”, “control of one’s mindset regarding diabetes management despite a limited scope of activity”, and “accepting ownership of self-management and continued management to the best of one’s ability.” A core theme was “living silently like robots dreaming of true freedom from type 1 diabetes.”

    The findings indicate that nurses should provide education, embracing the experience in diabetes management through trial and error among persons with type 1 diabetes.

    Low back pain (LPB) is a prevalent rheumatic and musculoskeletal disease and patients often experience physical discomfort and functional limitations. This study aimed to evaluate how subjective suffering relates to illness perceptions, pain intensity and psychological morbidity as well as to understand the mediator (direct and indirect) effects on functional disability.

    A cross-sectional study with 125 patients who received physiotherapy and answered the following instruments Illness Perception Questionnaire-Revised; Illness Subjective Suffering Inventory; Hospital Anxiety and Depression Scale and the Oswestry LBP Incapacity Questionnaire.

    In the structural equation modeling analysis, subjective suffering totally mediated the relationship between both emotional response (estimate=0.068, 95% highest posterior density interval =), consequences (estimate=0.118, 95% HPDI=) and functional disability. The relationship between coherence and disability was partially mediated by subjective suffering (estimate=-0.
