A multi-site, nurse-coordinated hepatitis C model of care in primary care and community services in Melbourne, Australia.

BACKGROUND: Hepatitis C virus (HCV) treatment through primary care and community-based services will be a critical component of HCV elimination. We evaluated a nurse-coordinated programme providing care across eight sites and analysed progression through the HCV care cascade. METHODS: People-accessing services from six primary care clinics, a homeless crisis accommodation provider and a mental health service were directly referred to nurses or engaged by nurses during regular clinic visits. Nurses supported HCV testing, treatment and follow-up. The prescription was provided by affiliated clinicians. Logistic regression was used to examine factors associated with treatment commencement and sustained virological response (SVR) testing. RESULTS: Of 640 people referred to and/or engaged by the nurses from January 2017 to July 2019, 518 had an HCV RNA test of whom 381 (74%) were HCV RNA positive. Treatment was commenced by 281 (74%) people of whom 161 had an SVR test, 157 (97.5%) were cured. Opioid agonist therapy was associated with treatment commencement (aOR 2.68, 95% CI 1.48-4.88). People who were homeless/unstably housed were less likely to commence treatment (aOR 0.45, 95% CI 0.23-0.87). Treatment prescription from a specialist (aOR 2.39, 95% CI 1.20-4.74) and recent injection drug use (<6 months) (aOR 2.15, 95% CI 1.07-4.31) was associated with SVR testing. CONCLUSION: A nurse-coordinated model of care led to high levels of HCV treatment uptake and cure amongst people attending primary care and community services. More tailored models of care may be beneficial for people who are homeless or have unstable housing. These results support primary care and community-based hepatitis C treatment.

Hepatitis C treatment in a co-located mental health and alcohol and drug service using a nurse-led model of care.

Hepatitis C virus (HCV) is more prevalent among people with experience of severe mental illness compared to the general population, due in part to higher levels of injecting drug use. Delivering HCV care through mental health services may reduce barriers to care and improve outcomes. A nurse-led HCV program was established in a co-located mental health and addiction service in Melbourne, Australia. People with a history of injecting drug use, including current use, were referred for HCV testing by nurses, with support provided on-site from a general practitioner and remotely from infectious disease and hepatology specialists. A nurse practitioner, general practitioner or specialists were able to prescribe HCV treatment. One-hundred and thirty people were referred to the nurse-led service, among whom 112 (86%) were engaged in care. Of those 112, 84 (75%) were found to have detectable HCV RNA, 70 (83%) commenced treatment; 28 (40%) prescriptions were nurse initiated, 19 (27%) were general practitioner initiated and 20 (29%) were prescribed from hospital clinics or elsewhere. All people with an SVR result (48/70) achieved HCV cure (intention to treat SVR 69%, per-protocol SVR 100%). Treatment commencement was highest among people prescribed opioid agonist therapy (28/29, 96%) compared to those who were not (18/26, 69%). In conclusion, a nurse-led, HCV service for people with severe mental illness including pathways to specialist support when needed can achieve high treatment uptake and cure. Further implementation work is required to improve treatment uptake, particularly among people not prescribed opioid agonist therapy, and to improve follow-up for SVR testing.

Further heterogeneity in Silver-Russell syndrome: PLAG1 deletion in association with a complex chromosomal rearrangement.

Silver-Russell syndrome (SRS) is a rare genetic condition primarily characterized by growth restriction and facial dysmorphisms. While hypomethylation of H19/IGF2:IG-DMR (imprinting control region 1 [IC1]) located at 11p15.5 and maternal uniparental disomy of chromosome 7 (upd[7]mat) are the most common genetic mechanisms responsible for SRS, the expanding body of literature describing alternative causative variants suggests SRS is a highly heterogeneous condition, also involving variation in the HMGA2-PLAG1-IGF2 pathway. We report a familial PLAG1 deletion in association with a complex chromosomal rearrangement. We describe two siblings with differing unbalanced chromosomal rearrangements inherited from a mother with a 5-breakpoint balanced complex rearrangement involving chromosomes 2, 8, and 21. The overlapping but diverse phenotypes in the siblings were characterized by shared SRS-like features, underlined by a PLAG1 whole gene deletion. Genetic analysis and interpretation was further complicated by a meiotic recombination event occurring in one of the siblings. This family adds to the limited literature available on PLAG1-related SRS. We have reviewed all currently known cases aiming to define the associated phenotype and guide future genetic testing strategies. The heterogeneity of SRS is further expanded by the involvement of complex cytogenomic abnormalities, imposing requirements for a comprehensive approach to testing and genetic counseling.

Alcohol and Other Drug (AOD) Education for Hospital Staff: An Integrative Literature Review.

Alcohol and Other Drug (AOD) education amongst hospital staff is often inadequate. This leads to suboptimal care of patients and is a missed opportunity for early identification and treatment. This integrative review evaluates the core features of current education for hospital-based doctors and nurses in AOD, including country of origin, content, duration, and pedagogy. The majority of included studies were conducted in the USA (72%), target alcohol rather than AOD in general (72%), adopted a purely medical model of treatment (94%), and utilised a Screening, Brief Intervention, and Referral to Treatment (SBIRT) model (94%). The overall quality of the studies was weak-moderate, which led to small effect sizes in most studies and limits the generalizability of any conclusions. More high quality research trials are needed to establish the core features of effective AOD education for hospital staff. Future research should include a focus on the psychosocial context of addiction, other drug use and the impact of negative attitudes on care delivery.

Vitamin D deficiency is common and associated with metabolic risk factors in patients with polycystic ovary syndrome.

Both vitamin D deficiency and polycystic ovary syndrome (PCOS) are associated with aspects of metabolic syndrome, but it is unclear whether vitamin D deficiency contributes to the metabolic disturbances commonly found in women with PCOS. This study sought to investigate (1) the prevalence of vitamin D deficiency in PCOS women in Scotland and (2) the relationship between vitamin D status and metabolic risk factors. This was an observational study on 52 women (25 in PCOS group and 27 in control group). Serum 25-hydroxyvitamin D concentrations less than 25 nmol/L were classified as severe vitamin D deficiency and were found in 44.0% and 11.2% of subjects in the PCOS and control groups, respectively (P = .047). Among the PCOS subjects, 25-hydroxyvitamin D concentrations were negatively correlated with body mass index (P = .033), C-reactive protein (P = .027), and free androgen index (P = .025) and positively correlated with quantitative insulin sensitivity check index (P = .035), high-density lipoprotein cholesterol (HDL-C) (P = .033), and sex hormone binding globulin (P = .038). Associations of vitamin D deficiency with quantitative insulin sensitivity check index and HDL-C were independent of body mass index and waist-to-hip ratio. Vitamin D deficiency is highly prevalent in PCOS women in Scotland, and a larger proportion of PCOS patients than control women were found to be vitamin D deficient. We also demonstrate correlations of vitamin D status with insulin sensitivity, HDL-C, and C-reactive protein in PCOS patients, which support the increasing evidence that vitamin D deficiency is associated with multiple metabolic risk factors in PCOS women.
