Colorectal polyps in young adults: a retrospective review of colonoscopy data from Toowoomba and the Darling Downs.

BACKGROUND: Polyps are the predominant precursors of colorectal cancer. In the past three decades, the incidence and mortality rates of colorectal cancer have been increasing in adults younger than 50 years. AIMS: The aim of this clinical audit was to evaluate the prevalence, characteristics and clinical associations of polyps in adults aged 18-49 years presenting to an established private gastroenterology clinic in the Toowoomba Darling Downs region. METHODS: The audit included data from 353 patient records held by the Toowoomba Gastroenterology Clinic. Data extracted from patient medical records through the Medical Director program software contained structured endoscopy/colonoscopy and histology reports of excised lesions of patients presenting to the clinic. The extract involved identifying all patients aged 18-49 years in the database from January 2019 to March 2022. Patients were screened based on audit inclusion and exclusion criteria. Patients were risk stratified for recommended surveillance intervals as per Australian Clinical Guidelines. RESULTS: Of the sample population, 33.4% were identified with polyps and 22.4% were identified with neoplastic polyps (NPs). A total of 6.7% of 18- to 29-year-old patients were identified with intermediate risk for colorectal cancer (CRC) screening, and 19.8% and 19.3% of 30- to 39-year-old and 40- to 49-year-old patients identified with intermediate or high risk for CRC screening respectively. Increased age, greater size of polyps and surveillance of previous polyps were associated with increased NP prevalence. CONCLUSIONS: Data from this audit supported the temporal trend of increasing prevalence of polyps in adults younger than 50 years. Patient cohorts aged 30-39 and 40-49 years may benefit from earlier first colonoscopies. Findings could be the impetus for future research in young adults presenting for colonoscopy.

Motivation and accessing care among drug treatment court involved women: A sequential, mixed-methods approach.

Drug treatment courts (DTC) address substance use disorders (SUD) but not cooccurrencing HIV or hepatitis C virus (HCV). This pilot explored feasibility and preliminary outcomes of the Women's Initiative Supporting Health (WISH) intervention and health-related motivation, both based in self-determination theory (SDT) regarding HIV/HCV and SUD treatment. WISH feasibility study: 79 DTC women completed a one-time survey regarding motivation and willingness to engage in future interventions. WISH intervention: 22 women from DTC with SUD and HIV or HCV received a 6-session, peer motivational enhancement health behavior-oriented interventions. Recruitment strategies were feasible. SDT-based measures demonstrated internal consistency in this under-studied population, with perceived competence/autonomy associationed with motivation to reduce HIV/HCV/SUD risk. Women DTC participants indicated acceptance and showed internally consistent results in SDT-based motivation measures These WISH feasibility and intervention pilot studies lay a foundation for future studies addressing motivation to access healthcare among women DTC participants.

FOCUS on women: Program evaluation of a pilot probation and primary care transitions clinic collaboration☆.

Gender-specific probation programs are needed for rising numbers of women on probation, as women's paths to probation differ from men's and are not as frequently addressed. Substance use, mental illness, health disparities, and barriers to treatment can contribute to women clients' unsuccessful completion of probation. The current study describes a process evaluation of the pilot Female Offenders Can Ultimately Succeed (FOCUS) program, which aimed to meet women probation clients' complex needs and improve their probation outcomes. Two women FOCUS Probation Officers had smaller-than-typical caseloads of 132 Medium- to Greatest-Risk women clients and received ongoing training in motivational and trauma-specific supervision strategies. To facilitate linkage to all needed treatment and social services, clients were referred to a primary care Transitions Clinic. Comparing non-FOCUS to FOCUS women clients with Violations of Probation, FOCUS clients had more successful completions of probation (higher non-punitive Restorations of Probation and lower punitive Revocations of Probation). At the Transitions Clinic, 52% of FOCUS clients received treatment. FOCUS clients and stakeholders provided narrative feedback reflecting a range of experiences in FOCUS, guiding future program implementation efforts. Promising outcomes from FOCUS demonstrate the potential of theory-based supervision and probation-medical collaboration to facilitate women clients' success in probation.

Inflorescence stem grafting made easy in Arabidopsis.

BACKGROUND: Plant grafting techniques have deepened our understanding of the signals facilitating communication between the root and shoot, as well as between shoot and reproductive organs. Transmissible signalling molecules can include hormones, peptides, proteins and metabolites: some of which travel long distances to communicate stress, nutrient status, disease and developmental events. While hypocotyl micrografting techniques have been successfully established for Arabidopsis to explore root to shoot communications, inflorescence grafting in Arabidopsis has not been exploited to the same extent. Two different strategies (horizontal and wedge-style inflorescence grafting) have been developed to explore long distance signalling between the shoot and reproductive organs. We developed a robust wedge-cleft grafting method, with success rates greater than 87%, by developing better tissue contact between the stems from the inflorescence scion and rootstock. We describe how to perform a successful inflorescence stem graft that allows for reproducible translocation experiments into the physiological, developmental and molecular aspects of long distance signalling events that promote reproduction. RESULTS: Wedge grafts of the Arabidopsis inflorescence stem were supported with silicone tubing and further sealed with parafilm to maintain the vascular flow of nutrients to the shoot and reproductive tissues. Nearly all (87%) grafted plants formed a strong union between the scion and rootstock. The success of grafting was scored using an inflorescence growth assay based upon the growth of primary stem. Repeated pruning produced new cauline tissues, healthy flowers and reproductive siliques, which indicates a healthy flow of nutrients from the rootstock. Removal of the silicone tubing showed a tightly fused wedge graft junction with callus proliferation. Histological staining of sections through the graft junction demonstrated the differentiation of newly formed vascular connections, parenchyma tissue and lignin accumulation, supporting the presumed success of the graft union between two sections of the primary inflorescence stem. CONCLUSIONS: We describe a simple and reliable method for grafting sections of an Arabidopsis inflorescence stem. This step-by-step protocol facilitates laboratories without grafting experience to further explore the molecular and chemical signalling which coordinates communications between the shoot and reproductive tissues.
