National Survey of Current Follow-up Protocols for Patients Treated for Endometrial Cancer in the UK. Clin Oncol (R Coll Radiol) 2024; 36:e146-e153. [PMID: 38548582 DOI: 10.1016/j.clon.2024.03.001] [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: 04/27/2023] [Revised: 12/12/2023] [Accepted: 03/08/2024] [Indexed: 05/06/2024]
Abstract
AIMS The aim of this study was to establish a baseline of national practice for follow-up after treatment for endometrial cancer in the UK. MATERIALS AND METHODS An online cross-sectional survey was developed and distributed through the Royal College of Radiologists via an email link to the audit leads of radiotherapy centres in the UK. The survey was conducted from November 2021 to 5 January 2022. The main themes assessed in the survey were the form, frequency and duration of follow-up practices. RESULTS There were a total of 43/61 (70%) complete responses. 93% of centres had a standard follow-up protocol and 7% who did not have a follow-up protocol discharged patients after the post-operative review. Five centres (13%) used molecular profiling to inform follow-up practices. Patient-initiated follow-up was mainly used in the cohort of patients who had surgery alone with no adjuvant treatment (68%, (19/28)). In the cohort who had face-to-face follow-up, the majority had pelvic examinations as part of their review and total follow-up for five years. 93% of respondents are interested in a national follow-up protocol. CONCLUSION Our data shows that there is national variation in practise with regard to follow-up of women treated for endometrial cancer. Many of the follow-up practises are based on conventional follow-up regimens and these may fail to address the more holistic needs of cancer survivors. Recent publication of updated guidance from the British Gynaecological Cancer Society may help standardise practise and provide a more relevant approach to follow-up for women treated for endometrial cancer.

Abstract
This longitudinal population-based study examines the association between maltreatment victimization experiences and the likelihood of intergenerational (dis)continuity of maltreatment. Our data include all individuals born in 1983/1984 in Queensland (QLD), Australia who are registered as parents via birth records and who experienced system contacts for maltreatment victimization in childhood (n = 2906). Child safety data on system contacts as a child victim and person responsible for harm to a child were obtained from the Department of Children, Youth Justice and Multicultural Affairs. Out-of-home care experiences and maltreatment frequency, timing, and type were examined. Results indicated that childhood maltreatment experiences significantly differed between parents who were not subsequently responsible for harm to a child (cycle breakers) and parents who were subsequently responsible for harm to a child (cycle maintainers). Different patterns of association were observed across sex. These findings highlight the importance of recognizing the heterogeneity of victim maltreatment experiences and associated risk of maltreatment for their children, and can inform effective and targeted interventions by tailoring these by sex and developmental period.

Capnodynamic monitoring of lung volume and pulmonary blood flow during alveolar recruitment: a prospective observational study in postoperative cardiac patients. J Clin Monit Comput 2023; 37:1463-1472. [PMID: 37243954 DOI: 10.1007/s10877-023-01033-1] [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: 10/26/2022] [Accepted: 05/08/2023] [Indexed: 05/29/2023]
Abstract
Alveolar recruitment manoeuvres may mitigate ventilation and perfusion mismatch after cardiac surgery. Monitoring the efficacy of recruitment manoeuvres should provide concurrent information on pulmonary and cardiac changes. This study in postoperative cardiac patients applied capnodynamic monitoring of changes in end-expiratory lung volume and effective pulmonary blood flow. Alveolar recruitment was performed by incremental increases in positive end-expiratory pressure (PEEP) to a maximum of 15 cmH2O from a baseline of 5 cmH2O over 30 min. The change in systemic oxygen delivery index after the recruitment manoeuvre was used to identify responders (> 10% increase) with all other changes (≤ 10%) denoting non-responders. Mixed factor ANOVA using Bonferroni correction for multiple comparisons was used to denote significant changes (p < 0.05) reported as mean differences and 95% CI. Changes in end-expiratory lung volume and effective pulmonary blood flow were correlated using Pearson's regression. Twenty-seven (42%) of 64 patients were responders increasing oxygen delivery index by 172 (95% CI 61-2984) mL min-1 m-2 (p < 0.001). End-expiratory lung volume increased by 549 (95% CI 220-1116) mL (p = 0.042) in responders associated with an increase in effective pulmonary blood flow of 1140 (95% CI 435-2146) mL min-1 (p = 0.012) compared to non-responders. A positive correlation (r = 0.79, 95% CI 0.5-0.90, p < 0.001) between increased end-expiratory lung volume and effective pulmonary blood flow was only observed in responders. Changes in oxygen delivery index after lung recruitment were correlated to changes in end-expiratory lung volume (r = 0.39, 95% CI 0.16-0.59, p = 0.002) and effective pulmonary blood flow (r = 0.60, 95% CI 0.41-0.74, p < 0.001). Capnodynamic monitoring of end-expiratory lung volume and effective pulmonary blood flow early in postoperative cardiac patients identified a characteristic parallel increase in both lung volume and perfusion after the recruitment manoeuvre in patients with a significant increase in oxygen delivery.Trial registration This study was registered on ClinicalTrials.gov (NCT05082168, 18th of October 2021).

Psychiatric illness and the risk of reoffending: recurrent event analysis for an Australian birth cohort. BMC Psychiatry 2023; 23:355. [PMID: 37221485 DOI: 10.1186/s12888-023-04839-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 05/03/2023] [Indexed: 05/25/2023] Open
Abstract
BACKGROUND Psychiatric illness is a well-established risk factor for criminal justice system involvement, but less is known about the relationships between specific psychiatric illnesses and reoffending. Research typically examines reoffending as a single discrete event. We examined the relationship between different psychiatric disorders and types of reoffending while accounting for multiple reoffending events over time. METHODS Data were drawn from a population cohort of 83,039 individuals born in Queensland, Australia, in 1983 and 1984 and followed to age 29-31 years. Psychiatric diagnoses were drawn from inpatient health records and offending information was drawn from court records. Descriptive and recurrent event survival analyses were conducted to examine the association between psychiatric disorders and reoffending. RESULTS The cohort included 26,651 individuals with at least one proven offence, with 3,580 (13.4%) of these individuals also having a psychiatric disorder. Individuals with any psychiatric disorder were more likely to reoffend compared to those without a disorder (73.1% vs. 56.0%). Associations between psychiatric disorders and reoffending varied across age. Individuals with a psychiatric disorder only started to accumulate more reoffending events from ~ 27 years, which accelerated up to age 31 years. There were both specificity and common effects in the associations between different psychiatric disorders and types of reoffending. CONCLUSIONS Findings demonstrate the complexity and temporal dependency of the relationship between psychiatric illness and reoffending. These results reveal the heterogeneity present among individuals who experience psychiatric illness and contact with the justice system, with implications for intervention delivery, particularly for those with substance use disorders.

Molnupiravir versus placebo in unvaccinated and vaccinated patients with early SARS-CoV-2 infection in the UK (AGILE CST-2): a randomised, placebo-controlled, double-blind, phase 2 trial. THE LANCET. INFECTIOUS DISEASES 2023; 23:183-195. [PMID: 36272432 PMCID: PMC9662684 DOI: 10.1016/s1473-3099(22)00644-2] [Citation(s) in RCA: 37] [Impact Index Per Article: 37.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/14/2022] [Revised: 09/06/2022] [Accepted: 09/12/2022] [Indexed: 11/06/2022]
Abstract
BACKGROUND The antiviral drug molnupiravir was licensed for treating at-risk patients with COVID-19 on the basis of data from unvaccinated adults. We aimed to evaluate the safety and virological efficacy of molnupiravir in vaccinated and unvaccinated individuals with COVID-19. METHODS This randomised, placebo-controlled, double-blind, phase 2 trial (AGILE CST-2) was done at five National Institute for Health and Care Research sites in the UK. Eligible participants were adult (aged ≥18 years) outpatients with PCR-confirmed, mild-to-moderate SARS-CoV-2 infection who were within 5 days of symptom onset. Using permuted blocks (block size 2 or 4) and stratifying by site, participants were randomly assigned (1:1) to receive either molnupiravir (orally; 800 mg twice daily for 5 days) plus standard of care or matching placebo plus standard of care. The primary outcome was the time from randomisation to SARS-CoV-2 PCR negativity on nasopharyngeal swabs and was analysed by use of a Bayesian Cox proportional hazards model for estimating the probability of a superior virological response (hazard ratio [HR]>1) for molnupiravir versus placebo. Our primary model used a two-point prior based on equal prior probabilities (50%) that the HR was 1·0 or 1·5. We defined a priori that if the probability of a HR of more than 1 was more than 80% molnupiravir would be recommended for further testing. The primary outcome was analysed in the intention-to-treat population and safety was analysed in the safety population, comprising participants who had received at least one dose of allocated treatment. This trial is registered in ClinicalTrials.gov, NCT04746183, and the ISRCTN registry, ISRCTN27106947, and is ongoing. FINDINGS Between Nov 18, 2020, and March 16, 2022, 1723 patients were assessed for eligibility, of whom 180 were randomly assigned to receive either molnupiravir (n=90) or placebo (n=90) and were included in the intention-to-treat analysis. 103 (57%) of 180 participants were female and 77 (43%) were male and 90 (50%) participants had received at least one dose of a COVID-19 vaccine. SARS-CoV-2 infections with the delta (B.1.617.2; 72 [40%] of 180), alpha (B.1.1.7; 37 [21%]), omicron (B.1.1.529; 38 [21%]), and EU1 (B.1.177; 28 [16%]) variants were represented. All 180 participants received at least one dose of treatment and four participants discontinued the study (one in the molnupiravir group and three in the placebo group). Participants in the molnupiravir group had a faster median time from randomisation to negative PCR (8 days [95% CI 8-9]) than participants in the placebo group (11 days [10-11]; HR 1·30, 95% credible interval 0·92-1·71; log-rank p=0·074). The probability of molnupiravir being superior to placebo (HR>1) was 75·4%, which was less than our threshold of 80%. 73 (81%) of 90 participants in the molnupiravir group and 68 (76%) of 90 participants in the placebo group had at least one adverse event by day 29. One participant in the molnupiravir group and three participants in the placebo group had an adverse event of a Common Terminology Criteria for Adverse Events grade 3 or higher severity. No participants died (due to any cause) during the trial. INTERPRETATION We found molnupiravir to be well tolerated and, although our predefined threshold was not reached, we observed some evidence that molnupiravir has antiviral activity in vaccinated and unvaccinated individuals infected with a broad range of SARS-CoV-2 variants, although this evidence is not conclusive.

Abstract
OBJECTIVE Most studies that examine psychiatric illness in people who offend have focused on incarcerated samples, with little known about the larger population of individuals with criminal justice system contact. We examine the overlap between proven offences and psychiatric diagnoses with an emphasis on experiences for Indigenous Australians. METHODS In a population-based birth cohort of 45,141 individuals born in Queensland, Australia, in 1990 (6.3% Indigenous), psychiatric diagnoses were identified from hospital admissions between ages 4/5 and 23/24 years and proven offences were identified from court records (spanning ages 10-24 years). Prevalence rates for offending, psychiatric diagnoses and their overlap were examined for Indigenous and non-Indigenous individuals. Associations between specific psychiatric diagnoses and types of offending were examined using logistic regressions. RESULTS There were 11,134 (24.7%) individuals with a finalised court appearance, 2937 (6.5%) with a diagnosed psychiatric disorder and 1556 (3.4%) with a proven offence and diagnosed psychiatric disorder, with Indigenous Australians significantly overrepresented across all outcomes. Compared with non-Indigenous Australians, Indigenous Australians were younger at their first court finalisation (Cohen's d = -0.62, 95% confidence interval = [-0.67, -0.57]), experienced a higher number of finalisations (d = 0.94, 95% confidence interval = [0.89, 1.00]) and offences (d = 0.64, 95% confidence interval = [0.59, 0.69]) and were more likely to receive custodial (d = 0.41, 95% confidence interval = [0.36, 0.46]) or supervised (d = 0.55, 95% confidence interval = [0.50, 0.60]) sentences. The overlap between offending and psychiatric illness was more pronounced for Indigenous Australians compared with non-Indigenous Australians (14.8% vs 2.7%). Substance use disorders were the most prevalent psychiatric diagnosis among individuals with a court finalisation (9.2%). CONCLUSIONS Indigenous Australians were significantly overrepresented in court finalisations and psychiatric diagnoses. Indigenous Australians with a psychiatric diagnosis were at highest risk of experiencing a court appearance, emphasising the importance of culturally appropriate mental health responses being embedded into the criminal justice system.

Safety, immunogenicity, and reactogenicity of BNT162b2 and mRNA-1273 COVID-19 vaccines given as fourth-dose boosters following two doses of ChAdOx1 nCoV-19 or BNT162b2 and a third dose of BNT162b2 (COV-BOOST): a multicentre, blinded, phase 2, randomised trial. THE LANCET. INFECTIOUS DISEASES 2022; 22:1131-1141. [PMID: 35550261 PMCID: PMC9084623 DOI: 10.1016/s1473-3099(22)00271-7] [Citation(s) in RCA: 81] [Impact Index Per Article: 40.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 04/19/2022] [Accepted: 04/19/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND Some high-income countries have deployed fourth doses of COVID-19 vaccines, but the clinical need, effectiveness, timing, and dose of a fourth dose remain uncertain. We aimed to investigate the safety, reactogenicity, and immunogenicity of fourth-dose boosters against COVID-19. METHODS The COV-BOOST trial is a multicentre, blinded, phase 2, randomised controlled trial of seven COVID-19 vaccines given as third-dose boosters at 18 sites in the UK. This sub-study enrolled participants who had received BNT162b2 (Pfizer-BioNTech) as their third dose in COV-BOOST and randomly assigned them (1:1) to receive a fourth dose of either BNT162b2 (30 μg in 0·30 mL; full dose) or mRNA-1273 (Moderna; 50 μg in 0·25 mL; half dose) via intramuscular injection into the upper arm. The computer-generated randomisation list was created by the study statisticians with random block sizes of two or four. Participants and all study staff not delivering the vaccines were masked to treatment allocation. The coprimary outcomes were safety and reactogenicity, and immunogenicity (anti-spike protein IgG titres by ELISA and cellular immune response by ELISpot). We compared immunogenicity at 28 days after the third dose versus 14 days after the fourth dose and at day 0 versus day 14 relative to the fourth dose. Safety and reactogenicity were assessed in the per-protocol population, which comprised all participants who received a fourth-dose booster regardless of their SARS-CoV-2 serostatus. Immunogenicity was primarily analysed in a modified intention-to-treat population comprising seronegative participants who had received a fourth-dose booster and had available endpoint data. This trial is registered with ISRCTN, 73765130, and is ongoing. FINDINGS Between Jan 11 and Jan 25, 2022, 166 participants were screened, randomly assigned, and received either full-dose BNT162b2 (n=83) or half-dose mRNA-1273 (n=83) as a fourth dose. The median age of these participants was 70·1 years (IQR 51·6-77·5) and 86 (52%) of 166 participants were female and 80 (48%) were male. The median interval between the third and fourth doses was 208·5 days (IQR 203·3-214·8). Pain was the most common local solicited adverse event and fatigue was the most common systemic solicited adverse event after BNT162b2 or mRNA-1273 booster doses. None of three serious adverse events reported after a fourth dose with BNT162b2 were related to the study vaccine. In the BNT162b2 group, geometric mean anti-spike protein IgG concentration at day 28 after the third dose was 23 325 ELISA laboratory units (ELU)/mL (95% CI 20 030-27 162), which increased to 37 460 ELU/mL (31 996-43 857) at day 14 after the fourth dose, representing a significant fold change (geometric mean 1·59, 95% CI 1·41-1·78). There was a significant increase in geometric mean anti-spike protein IgG concentration from 28 days after the third dose (25 317 ELU/mL, 95% CI 20 996-30 528) to 14 days after a fourth dose of mRNA-1273 (54 936 ELU/mL, 46 826-64 452), with a geometric mean fold change of 2·19 (1·90-2·52). The fold changes in anti-spike protein IgG titres from before (day 0) to after (day 14) the fourth dose were 12·19 (95% CI 10·37-14·32) and 15·90 (12·92-19·58) in the BNT162b2 and mRNA-1273 groups, respectively. T-cell responses were also boosted after the fourth dose (eg, the fold changes for the wild-type variant from before to after the fourth dose were 7·32 [95% CI 3·24-16·54] in the BNT162b2 group and 6·22 [3·90-9·92] in the mRNA-1273 group). INTERPRETATION Fourth-dose COVID-19 mRNA booster vaccines are well tolerated and boost cellular and humoral immunity. Peak responses after the fourth dose were similar to, and possibly better than, peak responses after the third dose. FUNDING UK Vaccine Task Force and National Institute for Health Research.

Abstract
This longitudinal population-based study aimed to understand the dual-system involvement of males who engage in domestic and family violence (DFV) and child maltreatment perpetration. Specifically, this study investigates the prevalence of male perpetration of DFV, child maltreatment, and dual-system involvement, and compares the frequency and nature of perpetration by males with single-system contact and males with dual-system contact. The effect of race (Indigenous Australian/non-Indigenous Australian) and parental status on dual-system involvement is also examined. This study utilizes data from the Queensland Cross-sector Research Collaboration repository. These data contain each contact an individual male born in 1983 or 1984 had with the Queensland civil court system as a respondent to a domestic violence order (DVO) and the Queensland statutory child protection system, where, after an investigation, they were identified as the person responsible for substantiated harm to a child. The results from the study show a high level of overlap between males who perpetrate DFV and child maltreatment. Of males identified as being responsible for substantiated harm to a child, 58% have also been a respondent of a DVO, and approximately 16% of male DVO respondents were identified as being responsible for substantiated harm to a child. Differences were found in the frequency and nature of perpetration by males with dual-system involvement compared to those with single-system contact for either DFV or child maltreatment. Our results also show differences for Indigenous status, parental status, number of maltreatment events, harm type, number of DVOs, and number of breaches of a DVO. The implications of this study for both policy and practice are discussed.

Abstract
BACKGROUND There is an historical separation between system responses to domestic violence (DV) and child maltreatment. Concerns have been noted that DV victims may be over-represented as parents responsible for harm to children in the child protection system. Although there is a growing acknowledgement of the high overlap between DV and child maltreatment within families, little empirical research has been conducted on this relationship. OBJECTIVE This study aims to longitudinally examine the overlap of being a victim of DV and a perpetrator of child maltreatment, along with the impact of dual-system involvement on the nature and frequency of the violence experienced. METHODS The data are linked longitudinal administrative data from the Queensland Cross-sector Research Collaboration (QCRC) repository. These data contain each contact every individual born in Queensland in 1983 or 1984 had with the Queensland DV civil court system and the Queensland statutory child protection system. RESULTS Of individuals identified as a perpetrator of child maltreatment, 45% have also been a victim of DV and approximately 22% of DV victims were identified as a perpetrator of child maltreatment. Our results also show differences based on Indigenous status, gender, parental status, number of substantiations, frequency of violence, harm type, and number of domestic violence orders. CONCLUSIONS There is considerable overlap between individuals who are victims of DV and individuals who perpetrate child maltreatment. This overlap was influenced by both gender and race/ethnicity. The implications of this study for both policy and practice are discussed.

Abstract
BACKGROUND Intronic WT1 mutations are usually causative of Frasier syndrome with focal segmental glomerulosclerosis as the characteristic nephropathy. Membranoproliferative glomerulonephritis is not commonly associated with disorders of sex development but has been recently identified as a WT1-associated nephropathy, but usually in cases of exonic mutations in either isolated Wilms tumor or Denys-Drash syndrome. METHODS The clinical and genetic data from 3 individuals are reported. RESULTS This report describes the kidney manifestations in 3 individuals from 2 unrelated families with Frasier syndrome intronic WT1 mutations, noting that 2 of the 3 individuals have histologically confirmed membranoproliferative glomerulonephritis. CONCLUSIONS These case reports support expansion of the clinical spectrum of the kidney phenotypes associated with Frasier syndrome providing evidence of an association between WT1 mutation and an immune complex-related membranoproliferative glomerulonephritis.

Abstract
Background
Carbon monoxide (CO) poisoning is one of the most critical health concerns worldwide due to severe clinical effects with high morbidity and mortality. Tissue hypoxia and cellular damage from CO poisoning results in oxidative stress. Organs and tissues with high O2 demand including central nervous system (CNS) and cardiovascular (CV) system are the most susceptible to this oxidative stress. We investigate and describe the cardiovascular manifestations in 350 patients who were admitted for moderate to severe CO poisoning and treated with hyperbaric oxygen (HBO2) therapy.
Purpose
This study was conducted to identify the common cardiovascular manifestations of carbon monoxide poisoning.

We retrospectively collected data on 350 consecutive adult patients treated for CO poisoning between January 2011 to April 2018. Cardiac biomarkers, EKG and carboxyhemoglobin (COHb) levels were obtained from pre-hospital sources including EMS (emergency medical services) and from outside hospital records at the time of transfer. Glasgow Coma Scale (GCS) measurements were obtained at initial pre-hospital evaluation and upon arrival to the emergency room. Patient demographics, CV, CNS history and cardiac risk factors including hypertension, hyperlipidemia, diabetes, smoking history were obtained from electronic medical record. Myocardial injury was defined by cardiac troponin I level of ≥0.05 ng/mL.
Results
There were 350 patients admitted for CO poisoning from 2011 to 2018. 72% of the patients received HBO treatment due to severity of their symptoms. The mean age was 47.3 years with 60% men, 89% of the admissions were accidental exposure. Cardiac biomarkers were elevated in 40% of the patients and with 21% having sinus tachycardia. 6% had ischemic EKG changes with 23% having regional wall motion abnormalities on echocardiogram. In terms of intervention, 83% of the patients with elevated cardiac biomarkers received HBO treatment, 9% underwent coronary angiogram out of which 50% were candidate for either percutaneous intervention (PCI) or coronary artery bypass graft (CABG). In hospital mortality amongst this population was 2%.
Conclusion
Myocardial injury is common and widely seen with CO poisoning as seen by elevated cardiac biomarkers in 40% of the tested population. Initial work up for patients with CO poisoning should include evaluation with an EKG and serial biomarkers. If an abnormality is detected, patient should undergo an echocardiogram. Further evaluation with coronary angiography may be warranted in patients with new left ventricular dysfunction or wall motion abnormalities, especially in patients with risk factors.

Abstract
Although most theoretical and policy approaches treat criminal behavior and child maltreatment as different issues, we examine the prevalence of those involved in both the criminal justice system and child protective services as perpetrators, assessing how several criminal career characteristics differ between dual-system and single-system offenders. Using longitudinal cohort data from the Queensland Cross-Sector Research Collaboration (QCRC), we found that while dual-system-involved offenders made up only 4% of the population, their proportion was much higher among those with a delinquent history, especially among females (males = 21%, females = 38%). Those involved with both systems were more serious offenders and child maltreatment perpetrators with respect to the number and versatility of system contacts. These findings suggest involvement in both the criminal justice and child welfare systems are part of an underlying vulnerability or predisposition toward antisocial behavior and represent an important overlap of service delivery that must be managed effectively.

Abstract
BACKGROUND Maltreatment victimization history is an established risk factor for child maltreatment across generations. However, many parents with a victimization history do not maltreat, and many parents with no victimization history do have victimized children. OBJECTIVES To understand differences in demographic and maltreatment risk factors across the following intergenerational patterns of maltreatment: cycle maintainers, cycle breakers, cycle initiators, and a comparison group (no maltreatment). PARTICIPANTS AND SETTING Data were drawn from a large population-based cohort in Queensland, Australia and included 32,574 biological parents and their children. Maltreatment experiences as a victim or person responsible for harm towards a child were obtained from the Queensland Child Protection System. METHODS Multinomial regression was completed with the full sample to compare the three maltreatment groups with the comparison group. Logistic regressions were conducted on all pairwise combinations of maltreatment groups. Models accounted for several demographic and maltreatment factors. RESULTS Compared with breakers, maintainers were more likely to be Indigenous (OR = 1.86), never married (OR = 0.34), younger at first birth (OR = 0.87), have ≥3 children (OR = 1.99), be younger at first-and older at last-maltreatment victimization (ORs = 0.97 and 1.07, respectively), and experience a higher frequency of victimization (OR = 1.05). Amongst maltreaters, males were significantly more likely to be initiators while females were more likely to be maintainers (OR = .62). There were few other differences between initiators and maintainers. CONCLUSIONS Meaningful differences among the three maltreatment groups were revealed suggesting that research should focus on the intergenerational discontinuity of maltreatment.

Abstract
Research examining the nature and extent of participation in antisocial behavior (ASB) in typically developing individuals during late adolescence and early adulthood remains rare. A self-report instrument for measuring participation in ASB was developed and administered to an Australian sample of 404 youth (64.9% females) aged 17 to 22-years using item-response theory methods. All participants reported involvement in multiple forms of ASB, although this involvement was skewed toward less serious behaviors, suggesting that engagement in these behaviors were common for typically developing youth. Unlike previous research, few sex differences were detected, with females' self-reported involvement in ASB similar to that of males. A need for ongoing longitudinal research in typically developing samples was highlighted, particularly on the transition to adulthood.

Abstract
Executive functions (EF) continue developing throughout adolescence, with immaturity in EF theorized to underlie risk-taking. 129 older adolescents and young adults (aged 17 to 22 years) were assessed using a battery of cool and hot EF tasks, and a behavioral measure of risk-taking propensity. Minimal age-related differences in EF performance were evident, confirming they were largely functionally mature by mid-adolescence. Inconsistent with the predictions of imbalance models of adolescent development, weaker EF was not associated with greater risk-taking propensity. The findings suggest that during later adolescence and early adulthood, not all forms of risk-taking are associated with EF.

Abstract
AIMS The aims of this study were to ascertain the comprehensive knowledge, perceptions, and attitudes of people from varying socioeconomic regions towards antibiotic use; identify the misperceptions and malpractices; and inform health policy and practice. METHOD EBSCO host databases, PubMed, and Google Scholar were searched to obtain relevant primary research papers within the years 2010-2018. Search phrases included the following: 'antibiotics use', 'community perceptions', 'public opinion, knowledge, behaviour, practices, perceptions'. Initially, selected papers were screened using the Preview, Question, Read, Summarize (PQRS) model. RESULTS Review of the 20 articles selected was based on six identified themes. It was found that insufficient knowledge and awareness of antibiotics use; self-medication and the use of leftover antibiotics; treating viral diseases with antibiotics or used as painkillers; expecting antibiotic prescription as a culmination of consultation; and the credibility of information obtained are issues that cut across different countries. CONCLUSION Evidence from this review suggests that misconceptions of antibiotic use are similar in different countries. Therefore, the need for the development and implementation of transferable policies as well as educating the public is necessary for the fight against ABR.

Strain-Dependent Inhibition of Clostridioides difficile by Commensal Clostridia Carrying the Bile Acid-Inducible ( bai) Operon. J Bacteriol 2020; 202:e00039-20.

Abstract
Clostridioides difficile is one of the leading causes of antibiotic-associated diarrhea. Gut microbiota-derived secondary bile acids and commensal Clostridia that carry the bile acid-inducible (bai) operon are associated with protection from C. difficile infection (CDI), although the mechanism is not known. In this study, we hypothesized that commensal Clostridia are important for providing colonization resistance against C. difficile due to their ability to produce secondary bile acids, as well as potentially competing against C. difficile for similar nutrients. To test this hypothesis, we examined the abilities of four commensal Clostridia carrying the bai operon (Clostridium scindens VPI 12708, C. scindens ATCC 35704, Clostridium hiranonis, and Clostridium hylemonae) to convert cholate (CA) to deoxycholate (DCA) in vitro, and we determined whether the amount of DCA produced was sufficient to inhibit the growth of a clinically relevant C. difficile strain. We also investigated the competitive relationships between these commensals and C. difficile using an in vitro coculture system. We found that inhibition of C. difficile growth by commensal Clostridia supplemented with CA was strain dependent, correlated with the production of ∼2 mM DCA, and increased the expression of bai operon genes. We also found that C. difficile was able to outcompete all four commensal Clostridia in an in vitro coculture system. These studies are instrumental in understanding the relationship between commensal Clostridia and C. difficile in the gut, which is vital for designing targeted bacterial therapeutics. Future studies dissecting the regulation of the bai operon in vitro and in vivo and how this affects CDI will be important.IMPORTANCE Commensal Clostridia carrying the bai operon, such as C. scindens, have been associated with protection against CDI; however, the mechanism for this protection is unknown. Herein, we show four commensal Clostridia that carry the bai operon and affect C. difficile growth in a strain-dependent manner, with and without the addition of cholate. Inhibition of C. difficile by commensals correlated with the efficient conversion of cholate to deoxycholate, a secondary bile acid that inhibits C. difficile germination, growth, and toxin production. Competition studies also revealed that C. difficile was able to outcompete the commensals in an in vitro coculture system. These studies are instrumental in understanding the relationship between commensal Clostridia and C. difficile in the gut, which is vital for designing targeted bacterial therapeutics.

Abstract
A framework for assessing photographs for the emotional and social health of young people (SHAPE) is described and tested, within the context of a rural program. Two independent raters assessed the photographs of participants. To assess inter-rater reliability, Cohen' K and Kendall's W were calculated. The two reviewers' assessments of photographs were in agreement. The assessment of emotional/behavioural display showed 82% agreement. Agreement between reviewers' judgements of proxemics (W = .866), interaction (W = .722), engagement (W = .932) and overall impression (W = .804) were all significant (p < .005). The method yielded results indicating that participants found gardening immediately engaging but their approach to equines exhibited a change from fascination to confidence during the program. The visual-diary method is a useful and sensitive method for research: where resources are limited; to complement traditional measures; for use with people who lack appropriate verbal communication or literacy skills to complete questionnaires; young children; other underrepresented groups.

Abstract
SETTING Terizidone/cycloserine (TRD/CS) is included in standard treatment regimens for multidrug-resistant tuberculosis (MDR-TB) in many countries. The steady state pharmacokinetics (PKs) of CS after TRD administration are not known. OBJECTIVES AND DESIGN We recruited in-patients treated with 250-750 mg oral TRD daily as part of standard treatment regimens for pulmonary MDR-TB in Cape Town, South Africa. Plasma CS assays were performed in samples taken pre-dose and at 2, 4, 6, 8 and 10 h post-dose. CS concentrations were measured using a validated liquid chromatography-tandem mass spectrometry method. Non-compartmental PK analyses were performed. RESULTS Of 35 participants enrolled, 22 were males, and 20 (57%) were infected with the human immunodeficiency virus; the median age was 37 years. The median duration on TRD at the time of sampling was 33 days (interquartile range [IQR] 28-39). The area under the concentration-time curve at 0-10 h (AUC0-10) was 319 μg.h/ml (IQR 267.5-378.7), and peak concentration was 38.1 μg/ml (IQR 32.6-47.2). On multiple regression, dose (mg/kg) was the only factor independently associated with AUC0-10. CONCLUSION Steady state concentrations of CS in patients treated with TRD for MDR-TB were higher than those reported with CS formulations. Our findings support once-daily dosing.

Abstract
BACKGROUND We recently reported that the administration of zoledronate every 18 months to osteopenic older women reduces the incidence of fractures. OBJECTIVE Here, we present a more detailed analysis of that trial to determine whether baseline clinical characteristics impact on the anti-fracture efficacy of this intervention. METHODS This is a prospective, randomized, placebo-controlled, double-blind trial in osteopenic postmenopausal women aged ≥ 65 years, to determine the anti-fracture efficacy of zoledronate. 2000 women were recruited using electoral rolls and randomized to receive 4 infusions of either zoledronate 5 mg or normal saline, at 18-month intervals. Each participant was followed for 6 years. Calcium supplements were not supplied. RESULTS Fragility fractures (either vertebral or nonvertebral) occurred in 190 women in the placebo group (227 fractures) and in 122 women in the zoledronate group (131 fractures), odds ratio (OR) 0.59 (95%CI 0.46, 0.76; P < 0.0001). There were no significant interactions between baseline variables (age, anthropometry, BMI, dietary calcium intake, baseline fracture status, recent falls history, bone mineral density, calculated fracture risk) and the treatment effect. In particular, the reduction in fractures appeared to be independent of baseline fracture risk, and numbers needed to treat (NNT) to prevent one woman fracturing were not significantly different across baseline fracture risk tertiles. CONCLUSIONS The present analyses indicate that the decrease in fracture numbers is broadly consistent across this cohort. The lack of relationship between NNTs and baseline fracture risk calls into question the need for BMD measurement and precise fracture risk assessment before initiating treatment in older postmenopausal women.

Abstract
SORT IT (Structured Operational Research Training InitiaTive) is a successful capacity building programme started 10 years ago to develop operational research skills in low- and middle-income countries. Public Health England (PHE) aims to embed a culture of research in front-line staff, and SORT IT has been adapted to train frontline health protection professionals at PHE North West (PHE NW) to collate, analyse and interpret routinely collected data for evidence-informed decision-making. Six participants from the PHE NW Health Protection team were selected to attend a two-module course in Liverpool, UK, in May and in November 2018. Five participants finished the course with completed papers on characteristics and burden of influenza-like illness in elderly care homes (two papers), use of dried blood spots for blood-borne virus screening in prisons, uptake of meningococcal ACWY (groups A, C, W-135 and Y) vaccine in schoolchildren and fires in waste management sites. The SORT IT course led to 1) new evidence being produced to inform health protection practice, and 2) agreement within PHE NW to continue SORT IT with two courses per year, and 3) showed how a research capacity building initiative for low- and middle-income countries that combines 'learning with doing' can be adapted and used in a high-income country.

Abstract
Beneficial modulation of the gut microbiota is an attractive therapeutic approach to improve the efficacy of vaccine-induced immunity. In this study, mice were supplemented with the prebiotic milk oligosaccharide 2'-fucosyllactose (2'FL) as well as a complex mixture of immune modulatory prebiotic short-chain galacto-oligosaccharides and long-chain fructo-oligosaccharides (scGOS/lcFOS) from different stages in early life. Adult mice were vaccinated with trivalent influenza vaccine (TIV) and both development of the gut microbiota and antibody-mediated vaccine responses were followed over time. Within the control group, female mice demonstrated a larger antibody response to TIV vaccination than male mice, which was accompanied by enhanced cytokine production by splenocytes and a higher percentage of plasma cells in skin draining lymph nodes. In addition, the prebiotic diet improved vaccine-specific antibody responses in male mice. Introduction of prebiotics into the diet modulated the gut microbiota composition and at the genus level several bacterial groups showed a significant interaction effect which potentially contributed to the immunological effects observed. This study provides insight in the effect of scGOS/lcFOS/2'FL in influenza vaccination antibody production.

The cost of infection: Argulus foliaceus and its impact on the swimming performance of the three-spined stickleback ( Gasterosteus aculeatus). J R Soc Interface 2018; 15:rsif.2018.0571.

Abstract
For fish, there can be multiple consequences of parasitic infections, including the physical impacts on swimming and the pathological costs of infection. This study used the three-spined stickleback (Gasterosteus aculeatus) and the ectoparasitic fish louse, Argulus foliaceus, to assess both physical (including form drag and mass) and pathological effects of infection. Both sustained (prolonged swimming within an open channel flume) and burst (C-start) swimming performance were measured on individual fish before (trials 1-2) and after infection (trials 3-5). Experimental infection occurred shortly before the third trial, when the physical impacts of infection could be separated from any subsequent pathology as transmission of adult parasites causes instantaneous drag effects prior to observable pathology. Despite the relatively large size of the parasite and corresponding increase in hydrodynamic drag for the host, there were no observable physical effects of infection on either sustained or burst host swimming. By contrast, parasite-induced pathology is the most probable explanation for reduced swimming performance across both tests. All sticklebacks displayed a preference for flow refugia, swimming in low-velocity regions of the flume, and this preference increased with both flow rate and infection time. This study suggests that even with large, physically demanding parasites their induced pathology is of greater concern than direct physical impact.

Restorative Justice Conferencing: Not a Panacea for the Overrepresentation of Australia's Indigenous Youth in the Criminal Justice System. INTERNATIONAL JOURNAL OF OFFENDER THERAPY AND COMPARATIVE CRIMINOLOGY 2018; 62:4067-4090.

Abstract
Restorative justice conferencing is a police diversionary strategy used extensively in Australian jurisdictions to channel young offenders away from formal court processing. Advocates view conferencing as culturally appropriate and a means to reduce the overrepresentation of Indigenous young people because it is rooted in Indigenous justice traditions. However, whether conferencing is effective at reducing recidivism by Indigenous young people compared with non-Indigenous young people remains unknown. We examine this using a longitudinal cohort of youth offenders from Australia. Propensity score matching was used to match Indigenous and non-Indigenous young people at their first conference and examined reoffending outcomes to explore its efficacy at reducing recidivism ( n = 394). Results indicate that, despite statistically controlling for factors related to reoffending, recidivism levels postconference were significantly higher for Indigenous young people. These results suggest that conferencing is unlikely to address the problem of Indigenous overrepresentation within Australia's youth justice system.

Contact X-ray Brachytherapy as an Adjunct to a Watch and Wait Approach is an Affordable Alternative to Standard Surgical Management of Rectal Cancer for Patients with a Partial Clinical Response to Chemoradiotherapy. Clin Oncol (R Coll Radiol) 2018; 30:625-633. [PMID: 30196845 DOI: 10.1016/j.clon.2018.06.010] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2018] [Revised: 05/25/2018] [Accepted: 06/10/2018] [Indexed: 11/28/2022]
Abstract
AIMS Emerging evidence suggests that contact X-ray brachytherapy (CXB) may increase the clinical complete response rate and durability when administered after standard chemoradiotherapy in patients with rectal cancer. The addition of CXB in partial responders is therefore probably cost-effective. The affordability of widening access to CXB in the UK, however, has not been evaluated. MATERIALS AND METHODS Decision analytical modelling with Monte Carlo simulation was used to evaluate long-term costs for the management of patients with rectal cancers who were given a CXB boost when a clinical complete response was not initially achieved following chemoradiotherapy in order to facilitate a watch and wait approach. A third-party payer (National Health Service) perspective was adopted, probabilistic sensitivity analysis was carried out and a scenario analysis was performed to investigate the effect of the number of referral centres and number of patients treated with CXB. RESULTS We estimate that 818 (95% confidence interval 628-1021) patients per year are eligible for CXB as an adjunct to a watch and wait approach in England and Wales. As this management is less costly than surgical management for each individual patient, the more patients treated, the more affordable the technology. Even if as few as 125 patients are treated nationally in 15 centres, the cost of implementing this technology would be less than £4 million. If the average number of patients treated in each centre is 30, this technology would be cost saving within 5 years. CONCLUSIONS The cost of CXB is not prohibitive according to the National Institute for Health and Care Excellence threshold for implementation of new technology and may even be cost saving within 5 years compared with standard surgical management, depending on the uptake of the technology and the number of referral centres.

Abstract
Endometrial carcinoma is the fourth most common cancer affecting women in the UK. Its most frequent sites of spread are to the pelvic and para-aortic lymph nodes, vagina and peritoneum. We report a case of a 63-year-old woman with known endometrial cancer who presented with left facial swelling and eye displacement. Investigations revealed an expansile soft-tissue density mass arising within the bone, centred on the left zygoma, with exophytic extension into the left maxillary antrum, infratemporal fossa and inferiorly into the orbit. Endoscopic biopsies were taken and histology confirmed metastatic deposits of endometrial cancer. Clinicians should be aware that distant spread of endometrial cancer is linked with advanced disseminated disease and palliative treatments should be considered.
