HIV-Tg26 mice injected with rAd-FGF-2 developed more significant proliferative and pro-fibrotic inflammatory lesions, similar to those seen in childhood HIVAN. These lesions were partially reversed in mice treated with the FGF/VEGF receptor tyrosine kinase inhibitor PD173074. In conclusion, we developed a new FGF-2-inducible model of childhood HIVAN, and showed that high circulating levels of FGF-2 precipitated HIVAN without inducing the renal expression of HIV-genes. These findings suggest that high plasma FGF-2 levels may be an independent risk factor for precipitating HIVAN in young children.The epididymis is composed of a pseudostratified epithelium comprised of various cell types. Studies have shown that rat basal cells share common properties with adult stem cells and begin to differentiate in vitro in response to fibroblast growth factor and 5α-dihydrotestosterone. The characterization of rat basal cells is therefore necessary to fully understand the role of these cells. The objectives of this study were to assess the ability of single basal cells to develop organoids and to assess their ability to self-renew and differentiate in vitro. We isolated basal cells from the rat epididymis and established 3-dimensional cell cultures from the basal and non-basal cell fractions. Organoids were formed by single adult epididymal basal cells. Organoids were dissociated into single basal cells which were able to reform new organoids, and were maintained over 10 generations. Long-term culture of organoids revealed that these cells could differentiated into cells expressing the principal cell markers aquaporin 9 and cystic fibrosis transmembrane conductance regulator. Electron microscopy demonstrated that organoids were comprised of several polarized cell types displaying microvilli and the ability to form tight junctions. Additionally, organoids could be formed by basal cells from either the proximal or distal region of the epididymis, and are able to secrete clusterin, a protein implicated in the maturation of spermatozoa. These data indicate that rat basal cells can be used to derive epididymal organoids, and further supports that notion that these may represent a stem cell population in the epididymis.C-terminal encoded peptides (CEPs) are peptide hormones which act as mobile signals coordinating important developmental programs. Previous studies have unraveled that CEPs are able to regulate plant growth and abiotic stress via cell-to-cell communication in Arabidopsis and rice; however, little is known about their roles in maize. Here, we examined the spatiotemporal expression pattern of ZmCEP1 and showed that ZmCEP1 is highly expressed in young ears and tassels of maize, particularly in the vascular bundles of ears. Heterologous expression of ZmCEP1 in Arabidopsis results in smaller plants and seed size. Similarly, overexpression of ZmCEP1 in maize decreased the plant and ear height, ear length, kernel size, and 100-kernel weight. Consistently, exogenous application of the synthesized ZmCEP1 peptide to the roots of Arabidopsis and maize inhibited root elongation. Knock-out of ZmCEP1 through CRISPR/Cas9 significantly increased plant and ear height, kernel size and 100-kernel weight. Transcriptome analysis revealed that knock-out of ZmCEP1 up-regulated a subset of genes involved in nitrogen metabolism, nitrate transport, sugar transport and auxin response. Thus, these results provide new insights into the genetic and molecular function of ZmCEP1 in regulating kernel development and plant growth, providing novel opportunities for maize breeding.Urinary incontinence (UI), the involuntary loss of urine, is a common health condition that may decrease the quality of life and which increases in incidence and prevalence with age. Recent epidemiologic data suggest an overall prevalence of 38% in women older than 60 years, increasing to 77% in older women living in nursing homes. Despite this high prevalence, incontinence remains underdiagnosed and undertreated in this age group. In a representative population of 7,000 participants drawn from the Irish Longitudinal Study of Ageing, 750 had UI of whom 285 (38%) had not sought the help of a health care professional. The reasons that older people do not seek help for incontinence are complex and multiplex. Stigma surrounding diagnosis, a sense of futility coupled to a notion that incontinence is a part of normal ageing and the fact that incontinence simply gets 'lost' in the midst of multimorbidity and frailty have all been shown to play a role. Active case finding has therefore been highlighted as a cornerstone of effective care in serial international guidelines.Objective and importance of study Considerable evidence suggests that adverse social determinants of health (SDH), such as poor education, unemployment, food and housing insecurity, interpersonal violence, inadequate social support and poverty, are key determinants of health and wellbeing. This prospective cohort study piloted a screening tool to collect individual SDH data in a South Australian hospital inpatient population. We explored participants' attitudes to SDH screening in brief follow-up interviews.
This mixed-methods study used an SDH screening tool to collect individual-level SDH data from inpatients living in a highly disadvantaged socio-economic area. Participants had a primary diagnosis of chronic obstructive pulmonary disease (COPD), heart failure (HF) or diabetes mellitus. Follow-up interviews were completed post discharge via telephone. Descriptive statistics were employed to examine the prevalence and type of adverse SDH reported by the sample. Thematic analysis was applied to explore partieening for SDH may potentially benefit doctors and patients. A larger study is required to more robustly characterise the adverse SDH affecting individuals in this population and to explore how the healthcare system might effectively intervene.Study objectives and importance The study aimed to explore how a 'self-in-the-system' approach was understood and applied by Healthy Together Community (HTC) practitioners, as part of Healthy Together Victoria's (HTV) systems approach to community-level health promotion. Self-in-the-system tactics were a means of systems practice within HTV, where practitioners viewed their connections to others as parts of the systems that surround them. It enabled them to intervene via exerting influence, by drawing upon relationships to leverage what people can contribute to achieve change. Study type and methods This qualitative research included 31 primary semistructured interviews. The initial participants were identified using purposive sampling and subsequent participants were nominated via snowball recruitment. The interview questions focused on participants' understanding of systems thinking and about how it had been developed and applied in HTCs. The interviews were recorded and transcribed verbatim.

Access in the early years to integrated community-based services that are flexible in their approach, holistic and culturally strong is a proven critical predictor of a child's successful transition to school and lifelong education and employment outcomes, providing long-term wellbeing. Studies show that participation in maternal and child health (MCH) services in Victoria, Australia, improve health outcomes for children and families, particularly for Aboriginal families. Poorer health outcomes and lower participation rates for these families in MCH services suggest there is a need for an urgent review of the current service model. The purpose of this paper is to outline the Early Assessment Referral Links (EARL) concept that was trialled in the Glenelg Shire in Victoria, Australia (2009-2014) to improve the engagement of Aboriginal families in MCH services.
Development of EARL involved the core principles of appreciative inquiry to change existing patterns of conversation and give voice to new and diversly Start Kindergarten. Identification of Aboriginal women and children at risk of vulnerability also improved with a dramatic increase in referrals for family violence and child protection, and decreased episodes of out-of-home care (OoHC) for children.
Evaluation of pilot outcomes indicate that the EARL concept improved women and children's access to and engagement with MCH services, and identified more families at risk of vulnerability than the traditional MCH service model, particularly for Aboriginal women and children.

Despite significant evidence of harms associated with high levels of sugar-sweetened beverage (SSB) consumption, and international moves towards regulation to curb overconsumption of such drinks, Australia has been slow to take policy action. This study provides in-depth insights into consumers' reactions to different SSB policy options.
Eight focus groups were undertaken with 59 regular SSB consumers and/or household purchasers, stratified by young adults aged 21-29 years (no children), parents aged 35-50 (with children at home); gender; and socio-economic status. Consumer responses to potential government intervention and policy options were explored using thematic analysis.
Three main themes were identified. Theme 1 describes participants' changing views on regulation of SSBs throughout the focus groups, expressed through shifts in understandings of personal responsibility and the role of government. It was noted that the term 'regulation' should be used judiciously, as it was widely misunderstood to infer bans. Theme 2 articulates the participants' preference for child-focused measures and educative measures such as clearer front-of-pack labelling. Taxation on SSBs was viewed more favourably if paired with investment into education. Theme 3 describes the parallels that participants drew between SSBs and other substances.
A comprehensive approach that includes education, child-focused interventions and regulatory approaches may increase acceptability of policy measures to curb overconsumption of SSBs.

Background Regular participation in physical activity during childhood and adolescence is important for good health. There is strong evidence of the physical and psychosocial benefits associated with recreational physical activity in these age groups, specifically in the context of organised sport. Most children in New South Wales (NSW), Australia, do not meet the recommended guidelines for physical activity, with financial cost commonly cited as a barrier to the initiation and maintenance of sport. The Active Kids program is a major policy initiative introduced in 2018 that aimed to overcome this barrier by implementing a statewide sport voucher scheme, allowing all NSW school-enrolled children (1.2 million) initial access to a $100 annual contribution towards organised sport and physical activity, with concurrent evaluation over the initial 4-year phase of the program.
This paper presents the protocol for evaluation of the Active Kids program, including an assessment of program impact on children's organised sport participation and recreational physical activity level, and analysis of the correlates of participation at individual, state and national levels.
