Effectiveness of hand hygiene campaigns and interventions across the League of Arab States: a region-wide scoping review. J Hosp Infect 2024; 147:161-179. [PMID: 38492646 DOI: 10.1016/j.jhin.2024.02.022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 02/22/2024] [Accepted: 02/24/2024] [Indexed: 03/18/2024]
Abstract
Hand hygiene is a standard public health practice for limiting the spread of infectious diseases, yet they are still not routine global health behaviours. This review aimed to examine the effectiveness of various hand hygiene interventions conducted across the League of Arab States, identify gaps in the existing literature, and propose areas for future research and intervention development. A scoping review was conducted across 16 databases for relevant publications published up to and including October 2023. Forty studies met the inclusion criteria; of these, 34 were hospital-based and six community-based. Of the reviewed studies, 24 provided adequate details that would enable replication of their intervention. Eighteen of the studies used some variation of the World Health Organization's Five Moments for intervention content or assessment. More than half (N = 25) reported healthcare worker or student hand hygiene behaviours as an outcome and 15 studies also included some form of patient-centred outcomes. Six studies specified the use of theory or framework for their evaluation design or intervention content, and four studies mentioned use of local government guidelines or recommendations. Future research should focus on bridging the literature gaps by emphasizing community-based studies and integrating cultural nuances into intervention designs. Additionally, applying theoretical frameworks to hand hygiene studies could enhance understanding and effectiveness, ensuring sustainable improvements in hygiene practices across diverse settings in the League of Arab States.

Abstract
BACKGROUND With pressures to decrease the financial burden of total hip arthroplasty (THA), it is imperative to understand the cost drivers of this procedure. This study evaluated operative and total encounter costs for two surgical approaches to THA-posterior (P) and direct anterior (DA). MATERIALS AND METHODS A total of 233 THAs (134 P and 99 DA) performed by two fellowship-trained arthroplasty surgeons from 2017 to 2022 were reviewed. Demographics, comorbidities, mobility status, operative time, length of stay, implants used, discharge location, and complications until final follow-up were recorded. Total encounter cost was collected and itemized. Multivariable regression analyses evaluated predictors of cost. RESULTS There were differences in age (67 years for DA and 63 years for P; P=.03), body mass index (28.0 kg/m2 for DA and 33.8 kg/m2 for P; P<.01), Elixhauser Comorbidity Index score (4.6 for DA and 5.6 for P; P=.04), and operative time (2.1 hours for DA and 1.9 hours for P; P<.01) between the two cohorts. The DA cohort trended toward shorter length of stay, with the highest percentage of patients discharged home (86.9%; P=.02). The P cohort had the lowest encounter ($9601 for DA and $9100 for P; P=.20) and intraoperative (including implant used) ($7268 for DA and $6792 for P; P<.01) costs. The DA cohort had a significantly higher cost of radiology during the encounter ($244; P<.01). Regression analysis demonstrated that length of stay and DA approach were both predictors of increased encounter cost. CONCLUSION The DA cohort had improved measures of health; however, this approach was associated with a higher operative cost and was predictive of increased encounter cost despite a shorter length of stay.

Quality-of-life measurement long-term after resection of colorectal liver metastases - is there an optimal assessment tool? HPB (Oxford) 2024; 26:352-361. [PMID: 37968202 DOI: 10.1016/j.hpb.2023.11.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 09/25/2023] [Accepted: 11/03/2023] [Indexed: 11/17/2023]
Abstract
BACKGROUND There is limited literature on health-related quality-of-life (HRQoL) in patients with colorectal liver metastases (CRLM). Furthermore, there is no consensus on which HRQoL tool is most appropriate. This study assessed the long-term HRQoL in patients who undergo liver resection for CRLM and assessed which HRQoL tool is most useful. METHODS This was a cross-sectional study of patients who had curative resection for CRLM between 2010 and June 2021. Three validated instruments were used: The European Organisation for Research and Treatment of Cancer (EORTC), which consists of the QLQ-C30 (a generic questionnaire) and QLQ-LMC21 (CRLM specific); the EuroQol-5D (EQ-5D) and the 36-Item Short Form Survey. RESULTS 121 patients underwent liver resection for CRLM, of which 85 were alive. There was a 61 % response rate (n = 52). The median post-operative time when the survey was completed was 4.0 years. Across all three questionnaires, patients performed exceptionally well in all domains, with median functional scores >90. The EQ-5D-5L VAS and the EROTC QLQ-C30 produced similar results. CONCLUSION This study demonstrates excellent long-term HRQoL in patients who undergo resection for CRLM. The EQ-5D questionnaire is the preferred questionnaire because it is shorter and simpler to complete than the other tools without compromising accuracy.

Abstract
BACKGROUND Biovigilance concerns are in tension with the need to increase organ donation. Cancer transmission risk from donor to recipient may be overestimated, as non-transmission events are rarely reported. We sought to estimate melanoma transmission risk in deceased organ donation and identify missed opportunities for donation in an Australian cohort with high melanoma prevalence. METHODS We used a population-based approach and linked deceased organ donors, transplant recipients, and potential donors forgone, 2010-2018, with the Central Cancer Registry (CCR), 1976-2018. We identified melanomas using ICD-O-3 classification, assessed the probability of transmission, and compared suspected melanoma history in potential donors forgone with melanoma notifications in the CCR. RESULTS There were 9 of 993 donors with melanoma in CCR; 4 in situ low-risk and 5 invasive high-to-unacceptable risk. Four were unrecognized before donation. Of 16 transplant recipients at risk, we found 0 of 14 transmission events (2 recipients had insufficient follow-up). Of 35 of 3588 potential donors forgone for melanoma risk alone, 17 were otherwise suitable for donation; 6 of 35 had no melanoma in CCR, 2 of 35 had in situ melanomas and 9 of 35 had thin invasive melanomas (localized, ≤0.8 mm thickness). CONCLUSIONS Our findings contribute to current evidence that suggests donors with melanomas of low metastatic potential may provide an opportunity to safely increase organ donation and so access to transplantation.

Inferior Outcomes for Patients Transferred Between Surgical Stages for Knee Periprosthetic Joint Infection. J Arthroplasty 2024; 39:490-493. [PMID: 37619801 DOI: 10.1016/j.arth.2023.08.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2023] [Revised: 08/01/2023] [Accepted: 08/04/2023] [Indexed: 08/26/2023] Open
Abstract
BACKGROUND Periprosthetic joint infection (PJI) in total knee arthroplasty may result in 2-stage revision surgery. There are limited data describing outcomes when the first stage is completed at an outside hospital and the patient is referred to a tertiary center. We hypothesized that patients have greater success when both surgeries occur at a single center. METHODS There were 25 knee PJI patients who presented with an antibiotic spacer and had a minimum 2-year follow-up who were retrospectively identified at a single tertiary referral center from 2014 to 2021. A cohort matched for age, sex, body mass index, Elixhauser comorbidity measure, spacer type, infectious organism, and year of surgery was established with patients who had both stages completed at the investigating institution. Modified Delphi success criteria of no subsequent surgery or reinfection with any species were compared. RESULTS The transferred group demonstrated a treatment success of 40% compared to 84% in the continuous group (P < .01). The transferred group was more likely to have an additional procedure between stages (44 versus 8%, P < .01), with a higher number of surgeries after primary total knee arthroplasty (4.8 versus 3.0, P < .01), between stages (1.4 versus 0.2, P < .01), and after second stage (0.8 versus 0.2, P = .03). The transferred group had longer durations between stages (20.1 versus 7.0 weeks, P < .01). CONCLUSION Patients who have PJIs transferred between stages demonstrated higher treatment failure. Surgeons should consider transfer early with a goal of continuous management by a single institution.

Abstract
Use of molecular sequencing modalities in periprosthetic joint infection diagnosis and organism identification has gained popularity recently. To date, there is no diagnostic test that reliably predicts infection eradication in patients with antibiotic spacers. The purpose of this study was to compare the diagnostic accuracy of next-generation sequencing (NGS), culture, the Musculoskeletal Infection Society (MSIS) criteria, and the criteria by Parvizi et al in patients with antibiotic spacers. In this retrospective study, aspirate or tissue samples were collected from 38 knee and 19 hip antibiotic spacers for routine diagnostic workup for the presence of persistent infection and sent to the laboratory for NGS. The kappa statistic along with statistical differences between diagnostic studies were calculated using the chi-square test for categorical data. The kappa coefficient for agreement between NGS and culture was 0.27 (fair agreement). The percentages of positive and negative agreement were 22.8% and 42.1%, respectively, with a total concordance of 64.9%. There were 12 samples that were culture positive and NGS negative. Eight samples were NGS positive but culture negative. The kappa coefficient was 0.42 (moderate agreement) when comparing NGS with MSIS criteria. In our series, NGS did not provide sufficient agreement compared with culture or MSIS criteria in the setting of an antibiotic spacer. A reliable diagnostic indicator for reimplantation has yet to be identified. [Orthopedics. 2024;47(1);46-51.].

Abstract
BACKGROUND AND HYPOTHESIS People on the kidney waitlist are less informed about potential suspensions. Disparities may exist among those who are suspended and who return to the waitlist. We evaluated the patient journey after entering the waitlist, including suspensions and outcomes, and factors associated with these transitions. METHODS We included all incident patients waitlist for their first transplant from deceased donors in Australia, 2006-19. We described all clinical transitions after entering the waitlist. We predicted the restricted mean survival time (unadjusted and adjusted) until first transplant by number of prior suspensions. We evaluated factors associated with transitions using flexible survival models and clinical endpoints using Cox models. RESULTS Of 8 466 patients waitlisted and followed over 45 757.4 person-years (median:4.8years), 6 741(80%) were transplanted, 381(5%) died waiting and 1 344(16%) were still waiting. 3 127(37%) people were suspended at least once. Predicted mean time from waitlist to transplant was 3.0 years(95%CI:2.8-3.2) when suspended versus 1.9 years(95%CI:1.8-1.9) when never suspended. Prior suspension increased likeliness of further suspensions 4.2-fold(95%CI:3.8-4.6) and returning to waitlist by 50%(95%CI:36-65%) but decreased likeliness of transplantation by 29%(95%CI:62-82%). Death risk while waiting was 12-fold(95%CI:8.0-18.3) increased when currently suspended. Australian non-Indigenous males were 13% (HR:1.13,95%CI:1.04-1.23) and Asian males 23% (HR:1.23,95%CI:1.06-1.42,) more likely to return to the waitlist compared to females of the same ethnicity. CONCLUSION The waitlist journey was not straightforward. Suspension was common, impacted chance of transplantation and meant waiting an average one year longer until transplant. We have provided estimates for, and factors associated with, suspension, re-listing and outcomes after waitlisting to support more informed discussions. This evidence is critical to further understand drivers of inequitable access to transplantation.

Clinical Observation, Management and Function Of low back pain Relief Therapies (COMFORT): A cluster randomised controlled trial protocol. BMJ Open 2023; 13:e075286. [PMID: 37989377 PMCID: PMC10668201 DOI: 10.1136/bmjopen-2023-075286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Accepted: 10/04/2023] [Indexed: 11/23/2023] Open
Abstract
INTRODUCTION Low back pain (LBP) is commonly treated with opioid analgesics despite evidence that these medicines provide minimal or no benefit for LBP and have an established profile of harms. International guidelines discourage or urge caution with the use of opioids for back pain; however, doctors and patients lack practical strategies to help them implement the guidelines. This trial will evaluate a multifaceted intervention to support general practitioners (GPs) and their patients with LBP implement the recommendations in the latest opioid prescribing guidelines. METHODS AND ANALYSIS This is a cluster randomised controlled trial that will evaluate the effect of educational outreach visits to GPs promoting opioid stewardship alongside non-pharmacological interventions including heat wrap and patient education about the possible harms and benefits of opioids, on GP prescribing of opioids medicines dispensed. At least 40 general practices will be randomised in a 1:1 ratio to either the intervention or control (no outreach visits; GP provides usual care). A total of 410 patient-participants (205 in each arm) who have been prescribed an opioid for LBP will be enrolled via participating general practices. Follow-up of patient-participants will occur over a 1-year period. The primary outcome will be the cumulative dose of opioid dispensed that was prescribed by study GPs over 1 year from the enrolment visit (in morphine milligram equivalent dose). Secondary outcomes include prescription of opioid medicines, benzodiazepines, gabapentinoids, non-steroidal anti-inflammatory drugs by study GPs or any GP, health services utilisation and patient-reported outcomes such as pain, quality of life and adverse events. Analysis will be by intention to treat, with a health economics analysis also planned. ETHICS AND DISSEMINATION The trial received ethics approval from The University of Sydney Human Research Ethics Committee (2022/511). The results will be disseminated via publications in journals, media and conference presentations. TRIAL REGISTRATION NUMBER ACTRN12622001505796.

Abstract
PURPOSE/OBJECTIVE(S) Published data supports the use of very high dose intensity modulated radiotherapy (IMRT) in achieving high efficacy and low toxicity for high-risk prostate cancer (HRPCa). This phase II multi-institutional non-randomized prospective dose escalation study using intensity modulated radiotherapy (IMRT) for high risk N0M0 prostate cancer was designed to investigate dose escalation using 1.8 Gy increments from baseline 75.6 Gy up to maximum 81 Gy, once dose volume constraints were adhered to. MATERIALS/METHODS Inclusion criteria were patients undergoing a radical course of RT for high and very high-risk disease, defined as one or more of the criteria ≥ T3*, ≥ Gleason 8, Prostate specific antigen (PSA) > 20ng/ml. All patients received Androgen Deprivation Therapy (ADT) and none had radiological evidence of distant metastatic disease. The primary objective was to determine if dose escalated IMRT for high risk localized prostate cancer could provide freedom from biochemical relapse (BR; PSA rising > nadir +2ng/mL or initiation of salvage hormone therapy) similar to that reported in the literature. The Kaplan-Meier method was used to estimate survival times. Secondary objectives included OS, Disease Free Survival (DFS), and the incidence and severity of Genito-urinary (GU), Gastro-intestinal (GI) and erectile dysfunction (ED) toxicities (CTCAE v.3). Toxicities and performance status were collected and graded weekly during RT, 2 months after completing RT, 8 months' post RT, and 6 monthly thereafter to year five and annually thereafter to year nine. RESULTS A total of 230 evaluable patients were enrolled between April 2009 and June 2016. The median follow-up was 7.3 years. The cumulative proportion of patients surviving without BR at 5 years was 91% (95% Confidence Interval (CI): 86% to 94%). Overall survival at 5 and 7 years was 92% (88% to 95%) and 89% (83% to 92%) respectively, while the cumulative proportion of patients free from disease was 89% (84% to 93%) at 5 years and 81% (75% to 86%) at 7 years. The incidence of acute G2 and G3 toxicities were; GU; 57.8% G2, 12.6% G3, GI; 15.2% G2, 0.4% G3, ED; 30.0% G2 and 61.7% G3. The incidence of late G2, G3 and G4 toxicities were; GU; 40.9% G2, 8.7% G3, GI; 36.5% G2, 2.2% G3, 0.4% G4, ED; 11.7% G2 and 86.1% G3. The percentage of patients receiving each dose level was; 3.5% received 75.6Gy in 42 fractions, 2.2% received 77.4Gy in 43 fractions, 93% received 81Gy in 45 fractions. CONCLUSION The findings indicate that high-dose IMRT is well tolerated and is associated with excellent long-term tumor-control outcomes in patients with localized high and very high-risk prostate cancer, with 91% of patients surviving at 5 years without biochemical relapse. The rates of long term G3 GU and GI toxicity were low at 8.7% and 0.4% respectively.

Abstract
AIMS Comprehensively investigate prescribing in usual care of hospitalized older people with respect to polypharmacy; potentially inappropriate medications (PIMs) according to Beers criteria; and cumulative anticholinergic and sedative medication exposure calculated with Drug Burden Index (DBI). Specifically, to quantify exposure to these measures on admission, changes between admission and discharge, associations with adverse outcomes and medication costs. METHODS Established new retrospective inpatient cohort of 2000 adults aged ≥75 years, consecutively admitted to 6 hospitals in Sydney, Australia, with detailed information on medications, clinical characteristics and outcomes. Conducted cross-sectional analyses of index admission data from cohort. RESULTS Cohort had mean (standard deviation) age 86.0 (5.8) years, 59% female, 21% from residential aged care. On admission, prevalence of polypharmacy was 77%, PIMs 34% and DBI > 0 in 53%. From admission to discharge, mean difference (95% confidence interval) in total number of medications increased 1.05 (0.92, 1.18); while prevalence of exposure to PIMs (-3.8% [-5.4, -2.1]) and mean DBI score (-0.02 [-0.04, -0.01]) decreased. PIMs and DBI score were associated with increased risks (adjusted odds ratio [95% confidence interval]) of falls (PIMs 1.63 [1.28, 2.08]; DBI score 1.21[1.00, 1.46]) and delirium (PIMs 1.76 [1.38, 1.46]; DBI score 1.42 [1.19, 1.71]). Each measure was associated with increased risk of adverse drug reactions (polypharmacy 1.42 [1.19, 1.71]; PIMs 1.87 [1.40, 2.49]; DBI score 1.90 [1.55, 2.15]). Cost (AU$/patient/hospital day) of medications contributing to PIMs and DBI was low ($0.29 and $0.88). CONCLUSION In this large cohort of older inpatients, usual hospital care results in an increase in number of medications and small reductions in PIMs and DBI, with variable associations with adverse outcomes.

Life Years Lost in Children with Kidney Failure: A Binational Cohort Study with Multistate Probabilities of Death and Life Expectancy. J Am Soc Nephrol 2023; 34:1057-1068. [PMID: 36918386 PMCID: PMC10278813 DOI: 10.1681/asn.0000000000000118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 01/13/2023] [Indexed: 03/16/2023] Open
Abstract
SIGNIFICANCE STATEMENT In children with kidney failure, little is known about their treatment trajectories or the effects of kidney failure on lifetime survival and years of life lost, which are arguably more relevant measures for children. In this population-based cohort study of 2013 children who developed kidney failure in Australia and New Zealand, most children were either transplanted after initiating dialysis (74%) or had a preemptive kidney transplant (14%). Life expectancy increased with older age at kidney failure, but more life years were spent on dialysis than with a functioning transplant. The expected (compared with the general population) number of life years lost ranged from 16 to 32 years, with female patients and those who developed kidney failure at a younger age experiencing the greatest loss of life years. BACKGROUND Of the consequences of kidney failure in childhood, those rated as most important by children and their caregivers are its effects on long-term survival. From a life course perspective, little is known about the experience of kidney failure treatment or long-term survival. METHODS To determine expected years of life lost (YLL) and treatment trajectory for kidney failure in childhood, we conducted a population-based cohort study of all children aged 18 years or younger with treated kidney failure in Australia (1980-2019) and New Zealand (1988-2019).We used patient data from the CELESTIAL study, which linked the Australian and New Zealand Dialysis and Transplant registry with national death registers. We estimated standardized mortality ratios and used multistate modeling to understand treatment transitions and life expectancy. RESULTS A total of 394 (20%) of 2013 individuals died over 30,082 person-years of follow-up (median follow-up, 13.1 years). Most children (74%) were transplanted after initiating dialysis; 14% (18% of male patients and 10% of female patients) underwent preemptive kidney transplantation. Excess deaths (compared with the general population) decreased dramatically from 1980 to 1999 (from 41 to 22 times expected) and declined more modestly (to 17 times expected) by 2019. Life expectancy increased with older age at kidney failure, but more life years were spent on dialysis than with a functioning transplant. The number of YLL ranged from 16 to 32 years, with the greatest loss among female patients and those who developed kidney failure at a younger age. CONCLUSIONS Children with kidney failure lose a substantial number of their potential life years. Female patients and those who develop kidney failure at younger ages experience the greatest burden.

Lifetime direct healthcare costs of treating colorectal cancer: a systematic review. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2023; 24:513-537.

Abstract
Colorectal cancer is a global public health issue and imposes a significant economic burden on populations and healthcare systems. This paper systematically reviews the literature to estimate the direct costs of colorectal cancer incurred during different phases of treatment (initial, continuing and end of life). MEDLINE, EMBASE, Web of science, Evidence-based medicine reviews: National health service economic evaluation database guide, econlit and grey literature from the 1st of January 2000 to the 1st of February 2020. The methodological quality of the included studies was assessed using the Evers' Consensus on health economic criteria checklist. In total, 39,489 records were retrieved, and 17 studies were included. Costs by phase of treatment varied due to heterogeneity. However, studies that examined average costs for each phase of treatment showed a V-shaped distribution where the initial and end of life phases contribute the most and the continuing phase the least. The initial phase ranged from $7,893 to $60,289; the continuing annual phase ranged from $2,323 to $15,744; and the end of life phase ranged from $15,916 to $99,687. Studies that provided the total cost of each phase conversely showed that the continuing phase was the highest contributor to the cost of treating CRC. This study estimates the cost of the contemporary management of colorectal cancer despite the methodological heterogeneity. These costs place a heavy burden on healthcare providers, patients and their families. Identifying these costs can impact health care budgets and guide policymakers in making informed decisions for the future.

Cost-effectiveness of Interventions to Increase Utilization of Kidneys From Deceased Donors With Primary Brain Malignancy in an Australian Setting. Transplant Direct 2023; 9:e1474. [PMID: 37090124 PMCID: PMC10118354 DOI: 10.1097/txd.0000000000001474] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2022] [Revised: 01/26/2023] [Accepted: 01/28/2023] [Indexed: 04/25/2023] Open
Abstract
Kidneys from potential deceased donors with brain cancer are often foregone due to concerns of cancer transmission risk to recipients. There may be uncertainty around donors' medical history and their absolute transmission risk or risk-averse decision-making among clinicians. However, brain cancer transmissions are rare, and prolonging waiting time for recipients is harmful. Methods We assessed the cost-effectiveness of increasing utilization of potential deceased donors with brain cancer using a Markov model simulation of 1500 patients waitlisted for a kidney transplant, based on linked transplant registry data and with a payer perspective (Australian government). We estimated costs and quality-adjusted life-years (QALYs) for three interventions: decision support for clinicians in assessing donor risk, improved cancer classification accuracy with real-time data-linkage to hospital records and cancer registries, and increased risk tolerance to allow intermediate-risk donors (up to 6.4% potential transmission risk). Results Compared with current practice, decision support provided 0.3% more donors with an average transmission risk of 2%. Real-time data-linkage provided 0.6% more donors (1.1% average transmission risk) and increasing risk tolerance (accepting intermediate-risk 6.4%) provided 2.1% more donors (4.9% average transmission risk). Interventions were dominant (improved QALYs and saved costs) in 78%, 80%, and 87% of simulations, respectively. The largest benefit was from increasing risk tolerance (mean +18.6 QALYs and AU$2.2 million [US$1.6 million] cost-savings). Conclusions Despite the additional risk of cancer transmission, accepting intermediate-risk donors with brain cancer is likely to increase the number of donor kidneys available for transplant, improve patient outcomes, and reduce overall healthcare expenditure.

Perioperative pain control represents the primary concern for patients considering outpatient shoulder arthroplasty: a survey-based study. J Shoulder Elbow Surg 2022; 31:e628-e633. [PMID: 35998781 DOI: 10.1016/j.jse.2022.07.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 06/27/2022] [Accepted: 07/07/2022] [Indexed: 02/01/2023]
Abstract
BACKGROUND Outpatient (OP) total shoulder arthroplasty (TSA) with same-day discharge can now be performed safely in appropriately selected patients. Patient knowledge and perspectives regarding OP TSA are yet unknown and such information may inform surgeon decision-making and provide a framework for addressing patient concerns. The goal of this study was to understand and quantify patient knowledge of and concerns for OP TSA, with a working hypothesis that majority of patients are unaware of OP TSA as a realistic option and that their primary concern would be postoperative pain control. METHODS This was a retrospective cohort study at a tertiary care academic medical center including patients who underwent anatomic or reverse shoulder arthroplasty and completed an OP TSA expectations questionnaire/survey. This survey was provided preoperatively and included demographic factors, self-rated health evaluation, and perioperative expectations. Surveys evaluated whether patients undergoing TSA had any prior awareness of OP TSA and evaluated their primary concern with same-day discharge. Secondary questions included an assessment of patient expectations of outcomes of outpatient vs. inpatient surgery as well as their expected length of inpatient stay. RESULTS A total of 122 patients who underwent anatomic and reverse shoulder arthroplasty completed the questionnaire and comprised the study cohort. Fifty-two (42.6%) of the patients were unaware that OP TSA was an option, and 26 (50%) of these were comfortable with the idea of OP TSA. Comfort with OP TSA was significantly associated with higher subjective patient-reported health status. Fifty-eight patients (47.5%) expected that following TSA they would require <24 hours of in-hospital postoperative care. The primary concern for patients considering OP TSA was postoperative pain control, endorsed by 44.3% of patients, compared with 13.1% of patients stating this would be their primary concern if admitted as an inpatient postoperatively. Pain control being a primary concern was significantly different between those considering outpatient vs. inpatient TSA. Most patients anticipated that OP shoulder arthroplasty would lead to a better (36%) or comparable (53%) outcome, whereas only 11% had concerns that it would lead to a worse outcome. CONCLUSION Expanding OP TSA crucially depends on awareness and education. Perceived ability to control pain is an important concern. Patients may benefit from preoperative counseling, including emphasizing a comprehensive postoperative pain management strategy.

Abstract
Abstract
Background
Population ageing, stroke treatment advances, changing models of care, and between-hospital heterogeneity in stroke outcomes demonstrate the necessity of continual audit of stroke care to support quality improvement at local and national levels, and to enhance patient recovery and wellbeing. This project aims to identify the core minimum datasets for acute and non-acute stroke care, and Patient-Reported Outcome Measures (PROMs), for integration in to the newly-developed Irish National Audit of Stroke (INAS), in addition to identifying resourcing needs and implementation procedures.
Methods
In Phase 1, a minimum dataset for acute stroke care was identified based on a scoping review of international practice and available guidelines. Phase 2 (ongoing) involves identifying datasets for non-acute rehabilitative and follow-up care based on a scoping review of international practice, iterative cycles of qualitative stakeholder engagement, and systematic review of PROMs. In Phase 3, a review of resourcing and data collection procedures used in stroke audits internationally will be used to produce an implementation strategy for data collection, contextualised to the Irish healthcare system.
Results
Twenty-one eligible international stroke registries were identified from the scoping review. Within Phase 1, core clinical and thrombectomy items in the Irish registry were benchmarked against internationally-collected items to identify common items and to generate an inventory of items that other registries collect that Ireland does not. Based on consensus agreement on the most frequently-occurring international items, as reviewed by key stakeholders, a core minimum dataset for audit of acute stroke care was delivered.
Conclusion
These minimum datasets shall act as the “gold standard” for evaluating stroke care in Ireland, by not only incorporating structure, process, and care quality outcome indicators, but also PROMs. The resultant datasets may inform policy and quality improvement initiatives, and shape health service delivery across the trajectory of stroke care, from hyper-acute care, to rehabilitation, and return to the community.

Cancer Mortality in People Receiving Dialysis for Kidney Failure: An Australian and New Zealand Cohort Study, 1980-2013. Am J Kidney Dis 2022; 80:449-461. [PMID: 35500725 DOI: 10.1053/j.ajkd.2022.03.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2021] [Accepted: 03/11/2022] [Indexed: 02/07/2023]
Abstract
RATIONALE & OBJECTIVE Cancer is a significant cause of morbidity in the population with kidney failure; however, cancer mortality in people undergoing dialysis has not been well described. We sought to compare cancer mortality in people on dialysis for kidney failure with cancer mortality in the general population. STUDY DESIGN A retrospective cohort study using linked health-administrative and dialysis registry data. SETTING & PARTICIPANTS All people receiving dialysis represented in the Australian and New Zealand Dialysis and Transplantation Registry, 1980-2013. EXPOSURE Dialysis; hemodialysis (HD) and peritoneal dialysis (PD). OUTCOME Death and underlying cause of death ascertained using health administrative data and classified using International Classification of Diseases, Tenth Revision, Australian Modification (ICD-10-AM) codes. ANALYTICAL APPROACH Indirect standardization on age at death, sex, year, and country to estimate standardized mortality ratios (SMR). RESULTS Over 269,598 person years of observation, 34,100 deaths occurred among 59,648 people on dialysis, including 3,677 cancer deaths. The relative risk of all-site cancer death in dialysis was twice (SMR, 2.4 [95% CI, 2.33-2.49]) that of the general population and highest for oral and pharynx cancers (SMR, 24.3 [95% CI, 18.0-31.5]) and multiple myeloma (SMR, 22.5 [95% CI, 20.3-23.9]). Women on dialysis had a significantly higher risk of all-site cancer mortality (SMR, 2.7 [95% CI, 2.59-2.89]) compared with men (SMR, 2.3 [95% CI, 2.17-2.36]) (P < 0.001). People on HD (SMR, 2.2 [95% CI, 2.11-2.30]) experienced greater excess deaths from all-site cancer compared with people on PD (SMR, 1.3 [95% CI, 1.23-1.44]). Excess deaths have gradually decreased over time for all-site, multiple myeloma, and kidney cancers (P < 0.001) but have not kept up with improvements in the general population. By contrast, among people receiving dialysis, excess deaths increased for colorectal and lung cancers (P < 0.001). LIMITATIONS Confirmation of cancer diagnoses and population incidence data were not available; inability to exclude pre-existing cancers. CONCLUSIONS People on dialysis experience excess all-site and site-specific cancer mortality compared with the general population. Mortality differs by modality type, age, and sex. Understanding the role of kidney failure and other morbidities in the treatment of cancer is important for shared decision-making regarding cancer treatments and identifying potential approaches to improve outcomes.

AcceSS and Equity in Transplantation (ASSET) New Zealand: Protocol for population-wide data linkage platform to investigate equity in access to kidney failure health services in New Zealand. PLoS One 2022; 17:e0273371. [PMID: 36006937 PMCID: PMC9409516 DOI: 10.1371/journal.pone.0273371] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Accepted: 08/07/2022] [Indexed: 11/29/2022] Open
Abstract
Background Kidney transplantation is considered the ideal treatment for most people with kidney failure, conferring both survival and quality of life advantages, and is more cost effective than dialysis. Yet, current health systems may serve some people better than others, creating inequities in access to kidney failure treatments and health outcomes. AcceSS and Equity in Transplantation (ASSET) investigators aim to create a linked data platform to facilitate research enquiry into equity of health service delivery for people with kidney failure in New Zealand. Methods The New Zealand Ministry of Health will use patients’ National Health Index (NHI) numbers to deterministically link individual records held in existing registry and administrative health databases in New Zealand to create the data platform. The initial data linkage will include a study population of incident patients captured in the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA), New Zealand Blood Service Database and the Australia and New Zealand Living Kidney Donor Registry (ANZLKD) from 2006 to 2019 and their linked health data. Health data sources will include National Non-Admitted Patient Collection Data, National Minimum Dataset, Cancer Registry, Programme for the Integration of Mental Health Data (PRIMHD), Pharmaceutical Claims Database and Mortality Collection Database. Initial exemplar studies include 1) kidney waitlist dynamics and pathway to transplantation; 2) impact of mental illness on accessing kidney waitlist and transplantation; 3) health service use of living donors following donation. Conclusion The AcceSS and Equity in Transplantation (ASSET) linked data platform will provide opportunity for population-based health services research to examine equity in health care delivery and health outcomes in New Zealand. It also offers potential to inform future service planning by identifying where improvements can be made in the current health system to promote equity in access to health services for those in New Zealand.

Understanding Type 2 Diabetes Self-Management in Racial/Ethnic Minorities: Application of the Extended Parallel Processing Model and Sensemaking Theory in a Qualitative Study. DIABETES EDUCATOR 2022; 48:372-386. [PMID: 35950550 DOI: 10.1177/26350106221116904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 11/03/2022]
Abstract
PURPOSE The purpose of the study was to understand the role of perceived disease threat and self-efficacy in type 2 diabetes (T2DM) patients' self-management by using the extended parallel processing model (EPPM) and sensemaking theory. METHODS Semistructured interviews (n = 25) were conducted with T2DM patients from an urban safety-net hospital. Participants were 50% male/female median age was 55 years and 76% were Black. Participants were categorized by EPPM group based on validated questionnaires (high/low disease threat [HT/LT]; high/low self-efficacy [HE/LE]). Nine were HT/HE, 7 HT/LE, 6 LT/HE, and 3 LT/LE. Interviews were transcribed and analyzed using inductive and deductive coding. Sensemaking theory was applied to contextualize and analyze data. RESULTS Those with HT indicated threat fluctuated throughout diagnosis but that certain triggers (eg, diabetic complications) drove changes in disease view. Those in the HT/HE group more frequently expressed disease acceptance, whereas the HT/LE group more often expressed anger or denial. HT/HE participants expressed having adequate social support and higher trust in health care providers. HT/LE participants reported limited problem-solving skills. In those with LT, the HE group took more ownership of self-management behaviors. The LT/LE group had heightened positive and negative emotional responses that appeared to limit their ability to perform self-care. They also less frequently described problem-solving skills, instead expressing reliance on medical guidance from their providers. CONCLUSIONS EPPM and sensemaking theory are effective frameworks for understanding how perceived health threat and self-efficacy may impede T2DM self-care. A greater focus on these constructs is needed to improve care among low-income minority patients, especially those with low threat and self-efficacy.

Abstract
Background Infections, including common communicable infections such as influenza, frequently cause disease after organ transplantation, although the quantitative extent of infection and disease remains uncertain. Methods A cohort study was conducted to define the burden of notifiable infectious diseases among all solid organ recipients transplanted in New South Wales, Australia, 2000–2015. Data linkage was used to connect transplant registers to hospital admissions, notifiable diseases, and the death register. Standardized incidence ratios (SIRs) were calculated relative to general population notification rates, accounting for age, sex, and calendar year. Infection-related hospitalizations and deaths were identified. Results Among 4858 solid organ recipients followed for 39 183 person-years (PY), there were 792 notifications. Influenza was the most common infection (532 cases; incidence, 1358 [95% CI, 1247–1478] per 100 000 PY), highest within 3 months posttransplant. Next most common was salmonellosis (46 cases; incidence, 117 [95% CI, 87–156] per 100 000 PY), then pertussis (38 cases; incidence, 97 [95% CI, 71–133] per 100 000 PY). Influenza and invasive pneumococcal disease (IPD) showed significant excess cases compared with the general population (influenza SIR, 8.5 [95% CI, 7.8–9.2]; IPD SIR, 9.8 [95% CI, 6.9–13.9]), with high hospitalization rates (47% influenza cases, 68% IPD cases) and some mortality (4 influenza and 1 IPD deaths). By 10 years posttransplant, cumulative incidence of any vaccine-preventable disease was 12%, generally similar by transplanted organ, except higher among lung recipients. Gastrointestinal diseases, tuberculosis, and legionellosis had excess cases among transplant recipients, although there were few sexually transmitted infections and vector-borne diseases. Conclusions There is potential to avoid preventable infections among transplant recipients with improved vaccination programs, health education, and pretransplant donor and recipient screening.

Evaluation of the SUCCESS health literacy app for Australian adults with chronic kidney disease: Study protocol for a pragmatic randomised controlled trial (Preprint). JMIR Res Protoc 2022; 11:e39909. [PMID: 36044265 PMCID: PMC9475407 DOI: 10.2196/39909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 06/27/2022] [Accepted: 06/28/2022] [Indexed: 12/04/2022] Open
Abstract
Background We developed a smartphone app—the SUCCESS (Supporting Culturally and Linguistically Diverse CKD Patients to Engage in Shared Decision-Making Successfully) app—to support Australian adults with kidney failure undertaking dialysis to actively participate in self-management and decision-making. The content of the SUCCESS app was informed by a theoretical model of health literacy that recognizes the importance of reducing the complexity of health information as well as providing skills necessary to access, understand, and act on this information. Objective The purpose of this study is to investigate the efficacy of the SUCCESS app intervention. Methods We designed a multicenter pragmatic randomized controlled trial to compare the SUCCESS app plus usual care (intervention) to usual care alone (control). A total of 384 participants receiving in-center or home-based hemodialysis or peritoneal dialysis will be recruited from six local health districts in the Greater Sydney region, New South Wales, Australia. To avoid intervention contamination, a pragmatic randomization approach will be used for participants undergoing in-center dialysis, in which randomization will be based on the days they receive hemodialysis and by center (ie, Monday, Wednesday, and Friday or Tuesday, Thursday, and Saturday). Participants undergoing home-based dialysis will be individually randomized centrally using simple randomization and two stratification factors: language spoken at home and research site. Consenting participants will be invited to use the SUCCESS app for 12 months. The primary endpoints, which will be assessed after 3, 6, and 12 months of app usage, are health literacy skills, evaluated using the Health Literacy Questionnaire; decision self-efficacy, evaluated using the Decision Self-Efficacy Scale; and rates of unscheduled health encounters. Secondary outcomes include patient-reported outcomes (ie, quality of life, evaluated with the 5-level EQ-5D; knowledge; confidence; health behavior; and self-management) and clinical outcomes (ie, symptom burden, evaluated with the Palliative care Outcome Scale–Renal; nutritional status, evaluated with the Patient-Generated Subjective Global Assessment; and intradialytic weight gain). App engagement will be determined via app analytics. All analyses will be undertaken using an intention-to-treat approach comparing the intervention and usual care arms. Results The study has been approved by Nepean Blue Mountains Human Research Ethics Committee (2020/ETH00910) and recruitment has begun at nine sites. We expect to finalize data collection by 2023 and publish the manuscript by 2024. Conclusions Enhancing health literacy skills for patients undergoing hemodialysis is an important endeavor, given the association between poor health literacy and poor health outcomes, especially among culturally diverse groups. The findings from this trial will be published in peer-reviewed journals and disseminated at conferences, and updates will be shared with partners, including participating local health districts, Kidney Health Australia, and consumers. The SUCCESS app will continue to be available to all participants following trial completion.

Abstract
Background Donor and other differences mean understanding drivers of transplant survival for type 1 diabetics is challenging. We aimed to compare outcomes of simultaneous pancreas‐kidney transplant over kidney transplant alone for people with end‐stage kidney disease (ESKD) and type 1 diabetes. Methods We performed a population‐based cohort study comparing outcomes from kidney alone and kidney‐pancreas transplants using registry data. Our study population was people in Australia and New Zealand with type 1 diabetes and ESKD who received a kidney transplant in 1984–2016. Primary outcomes were time to kidney transplant failure and all‐cause death. Secondary outcomes were time to cardiovascular and non‐cardiovascular death. We compared adjusted survival using Cox regression (hazard ratio HR and 95% confidence intervals CI). Results Of 1295 type 1 diabetics receiving a transplant, 430 (33%) received deceased donor kidney, 172 (13%) received living donor kidney, and 693 (54%) received pancreas‐kidney transplant. Compared to deceased donor kidney, pancreas‐kidney recipients had 40% lower rate of kidney transplant failure (adjusted HR 0.60; 95% CI 0.45–0.81; p = 0.001) and 34% lower mortality (adjusted HR 0.66; 95% CI 0.53–0.83; p < 0.001), driven by 49% reduction in cardiovascular mortality (adjusted HR 0.51; 95% CI 0.36–0.72; p < 0.001). Pancreas‐kidney recipients had similar reductions in transplant failure and mortality compared to living kidney recipients, after adjusting for transplant timing. Conclusions For people with type 1 diabetes, pancreas‐kidney transplant provides improved transplant and overall survival compared to deceased donor kidney alone. Living donor kidneys may perform just as well as pancreas‐kidney transplant if waiting times are short.

The Role of Medical Mistrust in Concerns about Tumor Genomic Profiling among Black and African American Cancer Patients. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19052598.

Abstract
Tumor genomic profiling (TGP) is used in oncology practice to optimize cancer treatment and improve survival rates. However, TGP is underutilized among Black and African American (AA) patients, creating potential disparities in cancer treatment outcomes. Cost, accuracy, and privacy are barriers to genetic testing, but medical mistrust (MM) may also influence how Black and AA cancer patients perceive TGP. From December 2019 to February 2020, 112 Black and AA adults from two outpatient oncology sites in Philadelphia, PA without a known history of having TGP testing conducted completed a cross-sectional survey. Items queried included sociodemographic characteristics, clinical factors, patient-oncologist relationship quality, medical mistrust, and concerns about TGP. A k-means cluster analysis revealed two distinct psychographic clusters: high (MM-H) versus low (MM-L) medical mistrust. Clusters were not associated with any sociodemographic or clinical factors, except for age (MM-H patients older than MM-L patients, p = 0.006). Eleven TGP concerns were assessed; MM-H patients expressed greater concerns than MM-L patients, including distrust of the government, insurance carriers, and pharmaceutical companies. TGP concerns varied significantly based on level of medical mistrust, irrespective of sociodemographic characteristics. Targeted communications addressing TGP concerns may mitigate disparities in TGP uptake among those with medical mistrust.

Abstract
BACKGROUND Safely increasing organ donation to meet need is a priority. Potential donors may be declined because of perceived blood-borne virus (BBV) transmission risk. With hepatitis C (HCV) curative therapy, more potential donors may now be suitable. We sought to describe potential deceased donors with increased BBV transmission risk. METHODS We conducted a cohort study of all potential organ donors referred in NSW, Australia, 2010-2018. We compared baseline risk potential donors to potential donors with increased BBV transmission risk, due to history of HIV, HCV or hepatitis B, and/or behavioral risk factors. RESULTS There were 624 of 5749 potential donors (10.9%) perceived to have increased BBV transmission risk. This included 298 of 5749 (5.2%) with HCV (including HBV coinfections) and 239 of 5749 (4.2%) with increased risk behaviors (no known BBV). Potential donors with HCV and those with increased risk behaviors were younger and had fewer comorbidities than baseline risk potential donors (P < 0.001). Many potential donors (82 with HCV, 38 with risk behaviors) were declined for donation purely because of perceived BBV transmission risk. Most were excluded before BBV testing. When potential donors with HCV did donate, they donated fewer organs than baseline risk donors (median 1 versus 3, P < 0.01), especially kidneys (odds ratio 0.08, P < 0.001) and lungs (odds ratio 0.11, P = 0.006). CONCLUSIONS Many potential donors were not accepted because of perceived increased BBV transmission risk, without viral testing, and despite otherwise favorable characteristics. Transplantation could be increased from potential donors with HCV and/or increased risk behaviors.

Abstract
Foodborne illnesses are a global public health issue. Responsibility to prevent foodborne disease is shared by many actors along the food supply chain, including consumers. However, consumers often lack knowledge about food safety and behaviors that can reduce risk. Consumers are often targeted for interventions to address these gaps, but a current comprehensive analysis of such interventions globally by type, geography, and outcome is lacking in the literature. In addition, there is a need to understand how individual interventions could be broadened to include the relationships between consumers and other actors in the food system, and how targeted communication strategies can affect behavior. We conducted a rigorous scoping review to assess consumer-facing food safety interventions carried out globally over the past 20 years, and categorized and analyzed them by type of intervention, methods, and outcomes to understand which interventions might be effective in changing consumer behavior, knowledge, attitudes, beliefs, and perceptions on food safety. Ninety-two interventions were reviewed, the majority of which were published in the last 10 years in North America. Most target adults, and 25% are directed at women and mothers. Health or risk communication interventions are becoming increasingly common to move beyond skill-based education and address risk perceptions of food safety that might motivate consumers. Only two studies addressed risk perception in consumers to potentially change food handlers' behavior outside of the home. This review suggests that focusing on risk perception combined with strategies that leverage emotion and trusted sources, such as respected peers or family members, might be useful strategies for interventions.

Abstract
Aim Cardiovascular mortality risk evolves over the lifespan of kidney failure (KF), as patients develop comorbid disease and transition between treatment modalities. Absolute cardiovascular death rates would help inform clinical practice and health‐care provision, but are not well understood across a continuum of dialysis and transplant states. We aimed to characterize cardiovascular death across the natural history of KF using a lifespan approach. Methods We performed a population‐based cohort study of incident patients commencing kidney replacement therapy in Australia and New Zealand. Cardiovascular deaths were identified using data linkage to national death registers. We estimated the probability of death and kidney transplant using multi‐state models, and calculated rates of graft failure and cardiovascular death across demographic factors and comorbidities. Results Among 60 823 incident patients followed over 381 874 person‐years, 25% (8492) of deaths were from cardiovascular disease. At 15 years from treatment initiation, patients had a 15.2% probability of cardiovascular death without being transplanted, but only 2.3% probability of cardiovascular death post‐transplant. Females had a 3% lower probability of cardiovascular death at 15 years (15.3% vs. 18.6%) but 4% higher probability of non‐cardiovascular death (54.5% vs. 50.8%). Within the first year of dialysis, cardiovascular mortality peaked in the second month and showed little improvement across treatment era. Conclusion Despite improvements over time, cardiovascular death remains common in KF, particularly among the dialysis population and in the first few months of treatment. Multi‐state models can provide absolute measures of cardiovascular mortality across both dialysis and transplant states. In this population‐based cohort study using multi‐state models (alive without kidney transplant [KT], CV death without KT, non‐CV death without KT, alive after first KT, CV death after first KT and non‐CV death after first KT), the probability of CV death was higher in non‐KT than KT patients at 15 years from treatment. In patients on dialysis, CV mortality was highest from the second month after commencing dialysis and remained high thereafter. Thus, the use of multi‐state models provides helpful information on impacts of different treatments with respect to serious outcomes.

Abstract
Thirty percent of US adults are COVID-19 vaccine hesitant, but little is known about them beyond demographics. We used segmentation and perceptual mapping techniques to assess perceptual differences in unvaccinated, vaccine hesitant adults in Philadelphia, PA (n = 110) who answered a cross-sectional survey in-person or online. The sample was 54% ethnic minority, 65% female, 55% earned less than $25,000 with a mean age of 44. K-means cluster analysis identified three audience segments based on reported trust of healthcare providers and personal COVID-19 impact (High Trust/Low impact [n = 34], Moderate Trust/High impact [n = 39], Low Trust/Low impact [n = 23]). Multidimensional scaling analysis created three-dimensional perceptual maps to understand differences in COVID-19 and vaccine perceptions. The Low Trust/Low Impact group showed higher agreement with items related to COVID-19 being a hoax (p = .034) and that minorities should be suspicious of government information (p = .009). Maps indicate vaccine messaging for all groups would need to acknowledge these items, but added messaging about trust of pharmaceutical companies, belief that COVID messages keep changing or that vaccines are not safe would also need to be addressed to reach different segments. This may be more effective than current messaging that highlights personal responsibility or protection of others.

Abstract
OBJECTIVE To evaluate sex differences in mortality among people with kidney failure compared with the general population. DESIGN Population based cohort study using data linkage. SETTING The Australian and New Zealand Dialysis and Transplant Registry (ANZDATA), which includes all patients receiving kidney replacement therapy in Australia (1980-2019) and New Zealand (1988-2019). Data were linked to national death registers to determine deaths and their causes, with additional details obtained from ANZDATA. PARTICIPANTS Of 82 844 people with kidney failure, 33 329 were female (40%) and 49 555 were male (60%); 49 376 deaths (20 099 in female patients; 29 277 in male patients) were recorded over a total of 536 602 person years of follow-up. MAIN OUTCOME MEASURES Relative measures of survival, including standardised mortality ratios, relative survival, and years of life lost, using general population data to account for background mortality (adjusting for country, age, sex, and year). Estimates were stratified by dialysis modality (haemodialysis or peritoneal dialysis) and for the subpopulation of kidney transplant recipients. RESULTS Few differences in outcomes were found between male and female patients with kidney failure. However, compared with the general population, female patients with kidney failure had greater excess all cause deaths than male patients (female patients: standardised mortality ratio 11.3, 95% confidence interval 11.2 to 11.5, expected deaths 1781, observed deaths 20 099; male patients: 6.9, 6.8 to 6.9, expected deaths 4272, observed deaths 29 277). The greatest difference was observed among younger patients and those who died from cardiovascular disease. Relative survival was also consistently lower in female patients, with adjusted excess mortality 11% higher (95% confidence interval 8% to 13%). Average years of life lost was 3.6 years (95% confidence interval 3.6 to 3.7) greater in female patients with kidney failure compared with male patients across all ages. No major differences were found in mortality by sex for haemodialysis or peritoneal dialysis. Kidney transplantation reduced but did not entirely remove the sex difference in excess mortality, with similar relative survival (P=0.83) and years of life lost difference reduced to 2.3 years (95% confidence interval 2.2 to 2.3) between female and male patients. CONCLUSIONS Compared with the general population, female patients had greater excess deaths, worse relative survival, and more years of life lost than male patients, however kidney transplantation reduced these differences. Future research should investigate whether systematic differences exist in access to care and possible strategies to mitigate excess mortality among female patients.

Abstract
BACKGROUND Transplant recipients are at high-risk of anal squamous cell cancer. We aimed to estimate the prevalence of high-risk human papillomavirus (HPV) and high-grade squamous intraepithelial lesion (HSIL) and assess characteristics associated with results METHODS: We recruited kidney transplant recipients in a single-center, 2015-2018. Participants completed a clinical questionnaire and received an anal-swab sent for HPV-DNA and cytological testing RESULTS: A total of 97 (74%) of 125 recipients approached consented to participate. Participants were median 47 (IQR 40-55) years, 60% male and median 4.5 (IQR .9-13) months-since-transplant. Of 86 assessable samples, at least one HPV genotype was detected in 15 (17%) participants; 1 (1%) HPV16, 8 (9%) other high-risk HPV. Of 76 assessable cytology samples, 9 (12%) showed evidence of abnormality; 1 (1%) HSIL, 1 (1%) atypical-squamous-cells, cannot exclude HSIL. Both HSIL recipients had high-risk HPV and biopsy confirmed HSIL. High-risk HPV was detected in six (9%) recipients with normal cytology. History of sexually transmitted infection, and abnormal cervical pap smear in women, was associated with high-risk HPV and HSIL CONCLUSIONS: High-risk HPV and HSIL testing may identify kidney transplant recipients at higher risk of anal cancer. Longitudinal studies are needed to describe the natural history of anal cancer in transplant recipients.

Abstract
For transgender (trans) women, community belonging may play an important role in shaping perceptions of HIV Pre-exposure Prophylaxis (PrEP). A cluster analysis was performed using data obtained from a survey administered to 128 trans women residing in Philadelphia, PA and the San Francisco Bay area, CA. Six items assessing feelings of community belongingness among trans women produced three distinct clusters. Associations were examined between cluster membership and perceptual items including beliefs about PrEP, experiences with healthcare, patient self-advocacy, and perceived trusted sources for PrEP information. Clusters were demographically comparable apart from age. There were significant differences noted between trust in various communication channels and perceptions of PrEP; the least community-connected cluster had less trust and more negative perceptions of PrEP. Analyses suggest that psychographic differences exist based on perceived community belongingness in this population, and this in turn may be consequential in determining how information about PrEP is communicated and diffused to trans women for whom PrEP may be indicated.

Abstract
Evidence on cancer transmission from organ transplantation is poor. We sought to identify cases of cancer transmission or non-transmission from transplantation in an Australian cohort of donors and recipients. We included NSW solid organ deceased donors 2000-2012 and living donors 2004-2012 in a retrospective cohort using linked data from the NSW Biovigilance Register (SAFEBOD). Central Cancer Registry (CCR) data 1972-2013 provided a minimum one-year post-transplant follow-up. We identified cancers in donors and recipients. For each donor-recipient pair, the transmission was judged likely, possible, unlikely, or excluded using categorization from international guidelines. In our analysis, transmissions included those judged likely, while those judged possible, unlikely, or excluded were non-transmissions. In our cohort, there were 2502 recipients and 1431 donors (715 deceased, 716 living). There were 2544 transplant procedures, including 1828 (72%) deceased and 716 (28%) living donor transplants. Among 1431 donors, 38 (3%) had past or current cancer and they donated to 68 recipients (median 6.7-year follow-up). There were 64 (94%) non-transmissions, and 4 (6%) transmissions from two living and two deceased donors (all kidney cancers discovered during organ recovery). Donor transmitted cancers are rare, and selected donors with a past or current cancer may be safe for transplantation.

Abstract
BACKGROUND Withdrawal from renal replacement therapy is common in patients with end-stage kidney disease (ESKD), but end-of-life service planning is challenging without population-specific data. We aimed to describe mortality after treatment withdrawal in Australian and New Zealand ESKD patients and evaluate death-certified causes of death. METHODS We performed a retrospective cohort study on incident patients with ESKD in Australia, 1980-2013, and New Zealand, 1988-2012, from the Australian and New Zealand Dialysis and Transplant registry. We estimated mortality rates (by age, sex, calendar year and country) and summarized withdrawal-related deaths within 12 months of treatment modality change. Certified causes of death were ascertained from data linkage with the Australian National Death Index and New Zealand Mortality Collection database. RESULTS Of 60 823 patients with ESKD, there were 8111 treatment withdrawal deaths and 26 207 other deaths over 381 874 person-years. Withdrawal-related mortality rates were higher in females and older age groups. Rates increased between 1995 and 2013, from 1142 (95% confidence interval 1064-1226) to 2706/100 000 person-years (95% confidence interval 2498-2932), with the greatest increase in 1995-2006. A third of withdrawal deaths occurred within 12 months of treatment modality change. The national death registers reported kidney failure as the underlying cause of death in 20% of withdrawal cases, with other causes including diabetes (21%) and hypertensive disease (7%). Kidney disease was not mentioned for 18% of withdrawal patients. CONCLUSIONS Treatment withdrawal represents 24% of ESKD deaths and has more than doubled in rate since 1988. Population data may supplement, but not replace, clinical data for end-of-life kidney-related service planning.

Abstract
Reverse transcription fluorescence resonance energy transfer-polymerase chain reaction (FRET-PCRs) were designed against the two most common mutations in severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) (A23403G in the spike protein; C14408T in the RNA-dependent RNA polymerase). Based on high-resolution melting curve analysis, the reverse transcription (RT) FRET-PCRs identified the mutations in american type culture collection control viruses, and feline and human clinical samples. All major makes of PCR machines can perform melting curve analysis and thus further specifically designed FRET-PCRs could enable active surveillance for mutations and variants in countries where genome sequencing is not readily available.

Abstract
Abstract
Background
Recent randomised trials showed benefit for anti-inflammatory therapies in coronary disease but excluded stroke. The prognostic value of blood inflammatory markers after stroke is uncertain and guidelines do not recommend their routine measurement for risk stratification.
Methods
We performed a systematic review and meta-analysis of studies investigating the association of C-reactive protein (CRP), interleukin-6 (IL-6) and fibrinogen and risk of recurrent stroke or major vascular events (MVEs). We searched EMBASE and Ovid Medline until 10/1/19. Random-effects meta-analysis was performed for studies reporting comparable effect measures.
Results
Of 2,515 reports identified, 39 met eligibility criteria (IL-6, n = 10; CRP, n = 33; fibrinogen, n = 16). An association with recurrent stroke was reported in 12/26 studies (CRP), 2/11 (fibrinogen) and 3/6 (IL-6). On random-effects meta-analysis of comparable studies, CRP was associated with an increased risk of recurrent stroke [pooled hazard ratio (HR) per 1 standard-deviation (SD) increase in loge-CRP (1.14, 95% CI 1.06-1.22, p < 0.01)] and MVEs (pooled HR 1.21, CI 1.10-1.34, p < 0.01). Fibrinogen was also associated with recurrent stroke (HR 1.26, CI 1.07-1.47, p < 0.01) and MVEs (HR 1.31, 95% CI 1.15-1.49, p < 0.01). Trends were identified for IL-6 for recurrent stroke (HR per 1-SD increase 1.17, CI 0.97-1.41, p = 0.10) and MVEs (HR 1.22, CI 0.96-1.55, p = 0.10).
Conclusion
Despite evidence suggesting an association between inflammatory markers and post-stroke vascular recurrence, substantial methodological heterogeneity was apparent between studies. Individual-patient pooled analysis and standardisation of methods are needed to determine the prognostic role of blood inflammatory markers and to improve patient selection for randomised trials of inflammatory therapies.

Abstract
There are limited data on the efficacy of antiparasitic treatments and husbandry methods to control nematode infections in captive populations of African green monkeys (AGMs), Chlorocebus sabaeus. In faecal egg count (FEC) tests, 10 of the 11 (91%) adult male AGMs captured from the large feral population on the island of St Kitts had evidence of nematode infections, mostly Capillaria (8/11, 73%), Trichuris trichiura (7/11, 64%) and strongylid species (7/11, 64%) specifically (hookworm and Trichostrongylus, 50/50), but also Strongyloides fuelleborni (1/11, 9%). When kept in individual cages with cleaning and feeding regimens to prevent reinfections and treated concurrently with ivermectin (300 µg/kg, given subcutaneously) and albendazole (10 mg/kg, given orally) daily for 3 days, 60% (6/10) of the AGMs were negative at a follow-up FEC at 3 months and by FEC and necropsy at the end of the study 5–8 months later. One monkey appeared to have been reinfected with T. trichiura after being negative by FEC at 3 months post-treatment. Four AGMs were positive for T. trichiura at the 3 month FEC follow-up but were negative at the end of the study after one further treatment regimen. Although initially being cleared of Capillaria following treatment, three AGMs were found to be infected at the end of the study. The ivermectin and albendazole treatment regimen coupled with good husbandry practices to prevent reinfections effectively controlled nematode infections in captive AGMs.

Abstract
Background Inflammation driven by pro-inflammatory cytokines is a new therapeutic target in coronary disease. Few data exist on the association of key upstream cytokines and post-stroke recurrence. In a prospective cohort study, we investigated the association between pivotal cytokines, high-sensitivity C-reactive protein (hsCRP) and one-year outcomes. Methods BIO-STROKETIA is a multi-center prospective cohort study of non-severe ischemic stroke (modified Rankin score ≤ 3) and transient ischemic attack. Controls were patients with transient symptoms attending transient ischemic attack clinics with non-ischemic final diagnosis. Exclusion criteria were severe stroke, infection, and other pro-inflammatory disease; hsCRP and cytokines (interleukin (IL) 6, IL-1β, IL-8, IL-10, IL-12, interferon-γ (IFN-γ), tumor-necrosis factor-α (TNF-α)) were measured. The primary outcome was one-year recurrent stroke/coronary events (fatal and non-fatal). Results In this study, 680 patients (439 stroke, 241 transient ischemic attack) and 68 controls were included. IL-6, IL-1β, IL-8, IFN-γ, TNF-α, and hsCRP were higher in stroke/transient ischemic attack cases (p ≤ 0.01 for all). On multivariable Cox regression, IL-6, IL-8, and hsCRP independently predicted one-year recurrent vascular events (adjusted hazard ratios (aHR) per-quartile increase IL-6 1.31, confidence interval (CI) 1.02–1.68, p = 0.03; IL-8 1.47, CI 1.15–1.89, p = 0.002; hsCRP 1.28, CI 1.01–1.62, p = 0.04). IL-6 (aHR 1.98, CI 1.26–3.14, p = 0.003) and hsCRP (aHR 1.81, CI 1.20–2.74, p = 0.005) independently predicted one-year fatality. IL-6 and hsCRP (adjusted odds ratio per-unit increase 1.02, CI 1.01–1.04) predicted poor functional outcome, with a trend for IL-1β (p = 0.054). Conclusion Baseline inflammatory cytokines independently predicted late recurrence, supporting a rationale for randomized trials of anti-inflammatory agents for prevention after stroke and suggesting that targeted therapy to high-risk patients with high baseline inflammation may be beneficial.

Abstract
OBJECTIVE Women on community supervision who inject drugs have significant unmet healthcare needs. However, it remains unclear how the intersection of community supervision and injection drug use influences healthcare experiences and service setting preferences. The present study examines whether the intersection of community supervision and injection drug use is associated with differences in women's healthcare beliefs, healthcare experiences, and service setting preferences. METHODS A secondary analysis was conducted on a previously collected sample of women who inject drugs recruited from a syringe exchange and social service organization for a cross-sectional survey. Participants (N = 64) were mostly White (75%), and more than a quarter were currently on probation or parole (26%). RESULTS Independent samples t-tests and chi-square tests revealed no significant differences on sociodemographic variables by community supervision status. There were no significant differences by community supervision status across seven indicators of healthcare confidence (ps > .05). However, results revealed significant differences in past experiences and beliefs about healthcare, health information seeking, and healthcare setting preferences by community supervision status (ps < .05), where women on community supervision less frequently sought health information and medical care outside of emergency departments. CONCLUSIONS Findings provide preliminary evidence about differences in the healthcare experiences and setting preferences of women who inject drugs on community supervision.

Looking backwards and forwards: tracking and persistence of weight status between early childhood and adolescence. Int J Obes (Lond) 2021; 45:870-878. [PMID: 33558641 DOI: 10.1038/s41366-021-00751-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2020] [Revised: 11/19/2020] [Accepted: 01/12/2021] [Indexed: 11/10/2022]
Abstract
BACKGROUND/OBJECTIVE Many studies have shown that child BMI or weight status tracks over time, but the demographic predictors of high tracking have not been investigated. Our objective was to identify demographic predictors of persistence (duration) of healthy weight and overweight/obesity throughout childhood, and to examine whether tracking was age dependent. METHODS We conducted secondary data analysis of 4606 children from the Birth cohort and 4983 children from the Kindergarten cohort of the Longitudinal Study of Australian Children with follow-up to age 12/13 and 16/17 years, respectively. Retrospective and prospective tracking were examined descriptively. Time-to-event analysis determined demographic predictors of persistence of healthy weight and overweight/obesity beyond age 4-5 years, after controlling for child BMI z-score. Weight status was determined using WHO methods. RESULTS Tracking of healthy weight was consistently higher than that of overweight/obesity, and incident overweight was equally likely throughout childhood and adolescence. Tracking of overweight was lower for children under 7 years than in middle childhood and adolescence (2-year probability 65%, compared with 80%; 2-year resolution of overweight 35 and 20%). Children of lower socioeconomic position, those from culturally and linguistically diverse backgrounds, and girls were more likely to move into overweight (hazard ratios [95%CI] for incident overweight: 1.39 [1.26-1.52], 1.16 [1.02-1.31] and 1.12 [1.02-1.23], respectively) and less likely to resolve their overweight (hazard ratios for resolution of overweight/obesity: 0.77 [0.69-0.85], 0.8 [0.69-0.92] and 0.79 [0.71-0.81], respectively) during childhood. However, persistence of weight status was not significantly affected by rurality or Indigenous status (P > 0.05). CONCLUSIONS Lowest tracking and highest natural resolution of overweight in children under 7 years suggests this may be an opportune time for interventions to reduce overweight. Primary and secondary prevention programmes during the school years should be designed with special consideration for lower socioeconomic communities, for culturally and linguistically diverse populations and for girls.

Abstract
BACKGROUND Transplant recipients experience excess cardiac mortality. We compared circulatory death rates in Australian and New Zealand kidney transplant recipients to the general population and identified risk factors for circulatory death in kidney transplant recipients. METHODS The primary cause of death for kidney transplant recipients aged ≥18 was established through ICD-10-AM codes using data linkage between the Australia and New Zealand dialysis and transplant registry and national death registers. We estimated standardized mortality ratios (SMRs) and developed a Fine-Gray competing risks model to determine risk factors for cardiac mortality. RESULTS Of 5089 deaths in 16 329 kidney transplant recipients (158 325 person-years), 918 (18%) were cardiac. An increased risk of circulatory death was associated with older age (P < 0.001), male sex (P < 0.001), longer dialysis duration (P = 0.004), earlier era of transplantation (P < 0.001), ever graft failure (P < 0.001), known coronary artery disease (P = 0.002), and kidney failure from diabetes or hypertension (P < 0.001). The cardiac SMR was 5.4 [95% confidence interval (CI): 5.0-5.8], falling from 8.0 (95% CI: 4.9-13.1) in 1988 to 5.3 (95% CI: 4.0-7.0) in 2013 (P < 0.001). Females, particularly young ones, had significantly higher relative cardiac mortality than men. In recipients aged 40 years, the cardiac SMR was 26.5 (95% CI: 15.0-46.6) in females and 7.5 (95% CI: 5.0-11.1) for males. CONCLUSIONS Cardiac risks remain elevated in kidney transplant recipients and may be under-recognized, and prevention and treatment interventions less accessed, less effective or even harmful in female recipients.

Interleukin-6, C-reactive protein, fibrinogen, and risk of recurrence after ischaemic stroke: Systematic review and meta-analysis. Eur Stroke J 2021; 6:62-71. [PMID: 33817336 PMCID: PMC7995315 DOI: 10.1177/2396987320984003] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2020] [Accepted: 12/06/2020] [Indexed: 01/02/2023] Open
Abstract
Background Recent randomised trials showed benefit for anti-inflammatory therapies in coronary disease but excluded stroke. The prognostic value of blood inflammatory markers after stroke is uncertain and guidelines do not recommend their routine measurement for risk stratification. Methods We performed a systematic review and meta-analysis of studies investigating the association of C-reactive protein (CRP), interleukin-6 (IL-6) and fibrinogen and risk of recurrent stroke or major vascular events (MVEs). We searched EMBASE and Ovid Medline until 10/1/19. Random-effects meta-analysis was performed for studies reporting comparable effect measures. Results Of 2,515 reports identified, 39 met eligibility criteria (IL-6, n = 10; CRP, n = 33; fibrinogen, n = 16). An association with recurrent stroke was reported in 12/26 studies (CRP), 2/11 (fibrinogen) and 3/6 (IL-6). On random-effects meta-analysis of comparable studies, CRP was associated with an increased risk of recurrent stroke [pooled hazard ratio (HR) per 1 standard-deviation (SD) increase in loge-CRP (1.14, 95% CI 1.06-1.22, p < 0.01)] and MVEs (pooled HR 1.21, CI 1.10-1.34, p < 0.01). Fibrinogen was also associated with recurrent stroke (HR 1.26, CI 1.07-1.47, p < 0.01) and MVEs (HR 1.31, 95% CI 1.15-1.49, p < 0.01). Trends were identified for IL-6 for recurrent stroke (HR per 1-SD increase 1.17, CI 0.97-1.41, p = 0.10) and MVEs (HR 1.22, CI 0.96-1.55, p = 0.10). Conclusion Despite evidence suggesting an association between inflammatory markers and post-stroke vascular recurrence, substantial methodological heterogeneity was apparent between studies. Individual-patient pooled analysis and standardisation of methods are needed to determine the prognostic role of blood inflammatory markers and to improve patient selection for randomised trials of inflammatory therapies.

Abstract
BACKGROUND Despite positive public attitudes toward solid organ donation in the United States, some of the lowest rates of donor designation persist among older adults and Latinx populations. AIMS To identify barriers and facilitators to organ donation and donor designation among lay health educators (promotoras) and mature Latina (50+ years). METHODS An explanatory sequential mixed-method design was employed, with telephone surveys followed by focus group interviews, to assess and understand the nuances of organ donation and donor designation knowledge, attitudes, and practices among promotoras and mature Latinas in Chicago (IL), Philadelphia (PA), and San Antonio (TX). Descriptive statistics summarized quantitative survey data; thematic content analysis was performed on qualitative data. RESULTS Twenty-nine promotoras and 45 mature Latina participated in both the surveys and focus groups (N = 74). Most participants (90%) had limited knowledge of organ donation but reported being "somewhat" or "strongly" in favor of donation (70%); 40.5% were registered donors. Participants lacked knowledge about the registration process and its legal standing and upheld concerns that registered donors would be vulnerable to organ traffickers or targets for murder. Themes emerging from the group interviews revealed additional barriers to designation including distrust of the medical establishment, perceptions of inequities in organ allocation, and family resistance to discussing death. DISCUSSION Low donor designation rates are primarily driven by concerns about organ trafficking and the fairness of the allocation system, particularly for undocumented immigrants. CONCLUSIONS The results informed development of a culturally targeted educational and communication skills intervention to increase donor designation in Latinx communities.

Abstract
IntroductionFemale life expectancies consistently exceed males in the general population. Yet, this survival advantage may not persist in the presence of a chronic disease due to biological differences or healthcare inequities.
Objectives and ApproachWe aimed to explore sex differences in mortality among people with end-stage kidney disease (ESKD). T he entire ESKD population in Australia, 1980-2013, and New Zealand,1988-2012, were included from the Australian and New Zealand Dialysis and Transplant Registry. Data linkage to national death registers was undertaken to ascertain deaths and their causes. We estimated relative measures of survival, including standardized mortality ratios (SMR), relative survival and expected life years lost, using general population data to account for background mortality, adjusting for country, age, sex and year.
ResultsOf 60,823 ESKD patients, there were 25,042 females (41%) and 35,781 males (59%). Mortality sex differences within the ESKD population were minor, but once compared to the general population, female ESKD patients had more excess deaths, worse relative survival and greater life years lost compared to male ESKD patients. Females had 11.5 SMR (95%CI:11.3-11.7) and males had 6.7 SMR (95%CI:6.7-6.8), with greater disparity among younger ages and from certain causes. Relative survival was consistently lower in females, with adjusted excess mortality 9% higher (95%CI:7-12%) in ESKD females. Average life years lost was 4-5 years greater in ESKD females compared to males across all ages. Kidney transplantation reduced the sex differences in excess mortality, with similar relative survival (p=0.42) and average life years lost reduced to 3-4 years for females.
Conclusion / ImplicationsThe impact of ESKD is more profound for women than men with greater excess mortality, however kidney transplantation attenuates these differences. Our findings show that chronic diseases and sex can compound to produce worse outcomes where women lose their survival advantage in the presence of ESKD.

Abstract
IntroductionRecipients of solid organ transplants are at risk of serious infection due to immunosuppression. Some infections are preventable with vaccination; infection rates vary with immunosuppression, vaccination rates and baseline disease prevalence. Both adherence with and response to vaccination in this population are variable, and optimum vaccination strategies continue to be refined.
Objectives and ApproachWe aimed to characterise the incidence and complications of vaccine-preventable infections in transplant recipients. Eligible participants received an organ transplant in New South Wales, Australia, in 2000-2015. Linkage was undertaken between transplant registries and the notifiable conditions information management system. Vaccine-preventable infections were diphtheria, Haemophilus influenzae type b, influenza, invasive pneumococcal disease, measles, mumps, pertussis, poliovirus, rubella and tetanus. Standardized incidence ratios (SIR) were calculated relative to Australian population notification rates, standardizing for gender, age and calendar year.
ResultsAmong 3,394 recipients, 399 vaccine-preventable infections affected 339 (10%) recipients. Influenza was the most common vaccine-preventable infection with 352 notifications among 305 recipients. Influenza cases were 8.9 times more common among transplant recipients than the general population (95%CI: 8.0-10.0). In 36 cases (10%), hospitalization was required, and 2 deaths due to influenza were reported.
There were 20 notifications of invasive pneumococcal disease (IPD) for 18 recipients. IPD occurred 10.2 times more often among transplant recipients than the general population (95%CI: 6.4-16.2). Most (n=13, 65%) cases were hospitalized, and one patient died from IPD.
Cases of pertussis occurred only slightly more often than in the general population (SIR 1.5, 95%CI: 1.0-2.3). Of 26 cases, there was one reported hospitalization and no deaths due to pertussis. Only one case of mumps, and no other vaccine-preventable infections, were reported.
ConclusionTransplant recipients have excess cases of influenza and IPD compared to the general population, although this has improved over time. The need for appropriate recipient vaccination is emphasized.

New Blood Borne Virus Infections Among Organ Transplant Recipients: A Data-Linked Cohort Study Examining Transmissions and De Novo Infections. Int J Popul Data Sci 2020.

Abstract
IntroductionSolid organ transplant recipients are at risk of infections, which may be either derived through transplantation or acquired later. Blood-borne viruses (BBV) are a particular concern for donor-derived transmissions. There is an increasing emphasis on biovigilance – monitoring the safety of donated organs. However, systematic surveillance to distinguish donor-transmitted infection from de novo post-transplant infection is challenging. Additional information can be obtained through linkage of administrative health data.
Objectives and ApproachWe aimed to identify donor-transmitted and de novo BBV infections among organ transplant recipients. We conducted a cohort study of all solid organ donor-recipient pairs in New South Wales, Australia, 2000-2015. Donor and recipient BBV infections were identified by linking transplant registries with administrative health data. Proven/probable donor-transmissions were identified among new recipient infections within 12 months of transplant, classified according to an international algorithm. All other new BBV infections were classified as de novo infections.
ResultsAmong 2,120 organ donors, 73 had a BBV infection (11/73 active, 62/73 past). Donors with BBV donated to 176 recipients, of whom 24/176 had the same BBV as their donor, and 152/176 did not; these 152 recipients were at risk of donor-transmission. Among those at risk, there were 3/152 proven/probable BBV transmissions (1 hepatitis C, 2 hepatitis B [HBV]) and 149/152 recipients with non-transmissions. All donor-transmissions were previously recognised by donation services, and were from donors with known BBV. There were no deaths from transmissions. There were 70 recipients with de novo BBV; 2/70 died from new HBV.
Conclusion / ImplicationsThis work confirms the safety of Australian organ donation, with no unrecognised BBV transmissions and many non-transmissions from donors with BBV. This may support increasing targeted donation from donors with BBV. However, de novo BBV infections were substantial and preventable. Data-linkage may be a useful adjunct to current biovigilance systems.

Abstract
IntroductionDonor suitability assessment is often time-sensitive, with imperfect information available at referral. Opportunities for donation may be missed if donors are rejected based on inaccurate information.
Objectives and ApproachWe sought to compare assessment of cancer transmission risk based on information available at referral (perceived) versus subsequently obtained (verified) detailed medical history, and to identify any missed opportunities for donation. We used data from the NSW Biovigilance Register, a cohort study of deceased organ donor referrals in New South Wales (NSW) 2010-2015. Referrals from NSW who had consent and were otherwise suitable for donation (except for perceived or verified tumour) were analysed. Perceived tumour details were obtained from NSW Organ and Tissue Donation Service referral logs, while verified details were based on the Central Cancer Registry and Admitted Patient Data Collection. Cancer transmission risk was graded using Transplantation Society of Australia and New Zealand guidelines.
ResultsAmong 772 referrals otherwise suitable for donation, 601 (78%) had accurately classified cancer transmission risk (κ=0.59). Overall, 53 suitable referrals were rejected due to cancer transmission risk (missed opportunities), including 49 (92%) with overestimated risk (perceived high, verified low/none), and 4 (8%) due to excessive risk aversion (perceived and verified low risk). Missed opportunities had overestimated transmission risk for tumours including leukaemia (8, 16%), lung (8, 16%), melanoma (7, 14%), brain (6, 12%), and breast (6, 12%).
Conclusion / ImplicationsDespite time pressure and limited information availability, there is moderate agreement between perceived and verified cancer transmission risk. Nevertheless, improved information availability (e.g. via data linkage) could meaningfully increase the number of actual donors.

Natural History of Cardiac and Peripheral Vascular Death In ESKD: An Australian And New Zealand Data Linkage Study. Int J Popul Data Sci 2020.

Abstract
IntroductionCardiovascular disease is a leading cause of death in patients with end-stage kidney disease (ESKD). However, ascertaining the impact of cardiovascular deaths has not been well characterised over long periods of follow-up and across different treatment states. Further insights into the lifetime risk of cardiovascular death are required to better inform clinical practice and economic planning.
Objectives and ApproachWe performed a population-based cohort study on incident patients receiving ESKD treatment from the Australian and New Zealand Dialysis and Transplant registry (ANZDATA). Cardiac/vascular deaths were determined from ICD-10-AM codes listed in the underlying cause of death obtained via data linkage with the Australian National Death Index and New Zealand Mortality Collection database. We estimated mortality rates from cardiac/vascular death across time from ESKD treatment, and calculated probability of death and transplant status over time using multistate models.
ResultsAcross 60,823 incident ESKD patients and 381,874 person-years of follow-up, 22% (7,551) of deaths were from cardiac/vascular disease. At 15 years from treatment, 15.6% of patients had died from cardiac/vascular causes, most of whom never received a transplant (13.6% vs 2.0% of cohort). Within the first year of dialysis, cardiac/vascular mortality was highest in the second month, at 3,632/100,000pys. Improvements in cardiac/vascular mortality with calendar year were only seen after 9 months of dialysis. Transplant recipients had consistently lower cardiac/vascular mortality rates (598/100,000 pys) compared to dialysis patients. However, comorbid cardiovascular disease was a risk factor for graft failure and death in transplant recipients (HR:1.52, 95% CI:1.42-1.62).
Conclusion / ImplicationsDespite improvements in cardiac/vascular outcomes over time, cardiovascular death remains common in ESKD, particularly in the first few months of treatment. A greater focus on secondary prevention in earlier stages of chronic kidney disease may improve outcomes in new ESKD patients.

Abstract
BACKGROUND Considerable research has explored psychosocial characteristics of individuals who seek aesthetic procedures as well as psychological changes experienced after successful treatment. Little research, however, has explored the experiences of transgender individuals who have undergone nonsurgical injectable procedures (NSIPs). OBJECTIVES This study examined theoretically relevant psychosocial characteristics of transgender individuals who have and have not undergone NSIPs. METHODS An online survey of demographic and psychosocial constructs was disseminated through transgender-specific support groups and Facebook groups from December 2019 to February 2020. Psychosocial measures included self-esteem (Rosenberg Self-Esteem Inventory), anticipated discrimination (Intersectional-Anticipated Discrimination), gender identity and physicality congruence (Transgender Congruence Scale), body image (Body Image Quality of Life Inventory), and overall satisfaction with facial appearance (FACE-Q Face Overall). The Mann-Whitney U test assessed differences by history of NSIPs, and the Kruskal-Wallis test assessed gender and racial differences. A P-value of <0.05 was considered significant. RESULTS Participants (N = 101) were transfeminine (n = 58), transmasculine (n = 31), gender-diverse (n = 12), and mostly (71%) white. Almost two-thirds of respondents (62%) reported using NSIPs; 6 participants reported undergoing NSIPs from non-licensed providers. History of NSIPs was associated with greater self-esteem (P < 0.01), less anticipated discrimination (P < 0.01), greater physicality and gender identity congruence(P < 0.001), greater body image quality of life (P < 0.001), and greater satisfaction with overall facial appearance (P < 0.01). CONCLUSIONS Use of NSIPs was associated with more positive psychosocial symptoms. Experiences with NSIPs may play an important role in psychosocial functioning for transgender individuals.

Effects of seasonality and land use on the diversity, relative abundance, and distribution of mosquitoes on St. Kitts, West Indies. Parasit Vectors 2020; 13:543. [PMID: 33138849 PMCID: PMC7607626 DOI: 10.1186/s13071-020-04421-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Accepted: 10/21/2020] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Mosquito surveys that collect local data on mosquito species' abundances provide baseline data to help understand potential host-pathogen-mosquito relationships, predict disease transmission, and target mosquito control efforts. METHODS We conducted an adult mosquito survey from November 2017 to March 2019 on St. Kitts, using Biogents Sentinel 2 traps, set monthly and run for 48-h intervals. We collected mosquitoes from a total of 30 sites distributed across agricultural, mangrove, rainforest, scrub and urban land covers. We investigated spatial variation in mosquito species richness across the island using a hierarchical Bayesian multi-species occupancy model. We developed a mixed effects negative binomial regression model to predict the effects of spatial variation in land cover, and seasonal variation in precipitation on observed counts of the most abundant mosquito species observed. RESULTS There was high variation among sites in mosquito community structure, and variation in site level richness that correlated with scrub forest, agricultural, and urban land covers. The four most abundant species were Aedes taeniorhynchus, Culex quinquefasciatus, Aedes aegpyti and Deinocerites magnus, and their relative abundance varied with season and land cover. Aedes aegypti was the most commonly occurring mosquito on the island, with a 90% probability of occurring at between 24 and 30 (median = 26) sites. Mangroves yielded the most mosquitoes, with Ae. taeniorhynchus, Cx. quinquefasciatus and De. magnus predominating. Psorophora pygmaea and Toxorhynchites guadeloupensis were only captured in scrub habitat. Capture rates in rainforests were low. Our count models also suggested the extent to which monthly average precipitation influenced counts varied according to species. CONCLUSIONS There is high seasonality in mosquito abundances, and land cover influences the diversity, distribution, and relative abundance of species on St. Kitts. Further, human-adapted mosquito species (e.g. Ae. aegypti and Cx. quinquefasciatus) that are known vectors for many human relevant pathogens (e.g. chikungunya, dengue and Zika viruses in the case of Ae. aegypti; West Nile, Spondweni, Oropouche virus, and equine encephalitic viruses in the case of Cx. quinqefasciatus) are the most wide-spread (across land covers) and the least responsive to seasonal variation in precipitation.
