RESUMEN
This study explores microplastic and cellulosic microparticle occurrences in the NE Atlantic, focusing on the Porcupine Bank Canyon and Porcupine Seabight. Water samples from depths ranging between 605 and 2126 m and Lophelia pertusa coral samples from 950 m depth were analysed. Microparticles were detected in deep-water habitats, with concentrations varying from 2.33 to 9.67 particles L-1 in the Porcupine Bank Canyon, notably lower at greater depths. This challenges the assumption of deeper habitats solely acting as microplastic sinks. We also found evidence of microparticle adsorption and ingestion by L. pertusa. The presence of microparticles in cold-water corals underscores their vulnerability to pollutants. Furthermore, the dominance of rayon microparticles in both water and coral samples raises questions about marine pollution sources, potentially linked to terrestrial origins. This research emphasises the critical need for comprehensive exploration and conservation efforts in deep-sea environments, especially to protect vital ecosystems like L. pertusa reefs.

Objective: Reports of financial exploitation have steadily increased among older adults. Few studies have examined neuropsychological profiles for individuals vulnerable to financial exploitation, and existing studies have focused on susceptibility to scams, one specific type of financial exploitation. The current study therefore examines whether a general measure of financial exploitation vulnerability is associated with neuropsychological performance in a community sample. Methods: A sample (n = 116) of adults aged 50 or older without dementia completed a laboratory visit that measures physical and psychological functioning and a neuropsychological assessment, the Uniform Data Set-3 (UDS-3) and California Verbal Learning Test-II. Results: After covarying for demographics, current medical problems, financial literacy, and a global cognition screen, financial exploitation vulnerability was negatively associated with scores on the Multilingual Naming Test, Craft Story Recall and Delayed Recall, California Verbal Learning Test-II Delayed Recall and Recognition Discriminability, Phonemic Fluency, and Trails B. Financial exploitation vulnerability was not associated with performance on Digit Span, Semantic Fluency, Benson Complex Figure Recall, or Trails A. Conclusions: Among older adults without dementia, individuals at higher risk for financial exploitation demonstrated worse verbal memory, confrontation naming, phonemic fluency, and set-shifting. These tests are generally sensitive to Default Mode Network functioning and Alzheimer's Disease neuropathology. Longitudinal studies in more impaired samples are warranted to further corroborate and elucidate these relationships.
RESUMEN
Pakistan harbours a large burden of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. We utilised repeat sero-surveys to assess progress achieved towards hepatitis elimination in Pakistan. Multilevel logistic regression evaluated the change in HBV infection (HBV surface antigen (HBsAg)-positive) prevalence and HCV exposure (HCV antibody (HCV-Ab)-positive) prevalence between two sero-surveys from 2007 and 2019 for Sindh province and associated risk factors. Adjusted odds ratios (aORs) were estimated and population-attributable fractions (PAF) for modifiable risk factors for HCV exposure. The 2007 and 2019 surveys included 8855 and 6672 individuals. HBsAg prevalence decreased from 2.6% (95% confidence intervals (95% CI): 2.2-2.9) in 2007 to 1.1% (95% CI: 0.8-1.3) in 2019, while HCV-Ab prevalence increased from 5.1% (95% CI: 4.6%-5.5%) to 6.2% (95% CI: 5.6%-6.8%). The age and gender-adjusted HBsAg prevalence decreased by 80% (aOR = 0.2, 95% CI: 0.1-0.4) among children and 60% (aOR = 0.4, 95% CI: 0.3-0.6) among adults over 2007-2019, while HCV-Ab prevalence decreased by 60% (aOR = 0.4, 95%CI:0.2-0.7) in children and increased by 40% (aOR = 1.4, 95% CI: 1.2-1.7) in adults. HCV-Ab prevalence was lower in adults with secondary (aOR = 0.6, 95% CI: 0.5-0.8) and higher (aOR = 0.5, 95%CI:0.3-0.8) education compared to illiterates and higher among adults reporting blood transfusion (aOR = 1.7, 95% CI: 1.2-2.4), family history of hepatitis (aOR = 2.5, 95% CI: 1.9-3.3), past year medical injection (aOR = 2.1, 95% CI: 1.6-2.7), being tattooed (aOR = 1.4, 95% CI: 1.0-1.9) and shaved by traditional barber (aOR = 1.2, 95% CI: 1.0-1.5). Modifiable risk factors accounted for 45% of HCV exposure, with medical injection(s) accounting for 38% (95%CI,25.7-48.4%). Overall HCV has increased over 2007-2019 in Sindh province, while HBV prevalence has decreased. Medical injections should be an important focus of prevention activities.

RESUMEN
This study examined the interactive effect of subjective age on the relationship between global cognition and susceptibility to scams. Sixty-five participants underwent an assessment of global cognition (Mini Mental State Examination; MMSE), reported their perceived age (i.e., subjective age), and responded to a self-report questionnaire assessing scam susceptibility. A main effect of global cognition on scam susceptibility was found (p = .028); there was no main effect of subjective age (p = .819). An interaction between global cognition and subjective age was found (p = .016). Examination of conditional effects demonstrated that the relationship between cognition and scam susceptibility was not significant amongst those with subjective ages below one standard deviation of the mean, but was significant for those whose subjective ages fell around or above the mean. Findings suggest that individuals with older subjective ages may be particularly vulnerable to the negative effects of lower cognition on scam susceptibility.

People with substance use disorders (SUD) have a high prevalence of chronic hepatitis C virus (HCV) infection and mental health disorders. We aimed to assess the impact of integrated HCV treatment on psychological distress measured by Hopkins-symptom-checklist-10 (SCL-10). This multi-center randomized controlled trial evaluated psychological distress as a secondary outcome of integrated HCV treatment (INTRO-HCV trial). From 2017 to 2019, 289 participants were randomly assigned to receive either integrated or standard HCV treatment with direct-acting antiviral therapy. Integrated HCV treatment was delivered in eight decentralized outpatient opioid agonist therapy clinics and two community care centers; standard treatment was delivered in internal medicine outpatient clinics at centralized hospitals. Participants in the integrated treatment arm had a sustained virologic response of 93% compared to 73% for those in standard treatment arm. Psychological distress was assessed using SCL-10 prior to initiation of HCV treatment and 12 weeks after treatment completion. The mean SCL-10 score prior to HCV treatment was 2.2 (standard deviation [SD]: 0.7) for patients receiving integrated HCV treatment and 2.2 (SD: 0.8) for those receiving standard HCV treatment. Twelve weeks after the end of treatment, the mean SCL-10 score change was - 0.1 (- 0.3;0.0) in the integrated compared to the standard arm. Psychological distress did not substantially change during the treatment period and was not significantly different between the treatment arms.

BACKGROUND: Racial and ethnic minoritized groups are disproportionately at risk for Alzheimer's Disease (AD), but are not sufficiently recruited in AD neuroimaging research in the United States. This is important as sample composition impacts generalizability of findings, biomarker cutoffs, and treatment effects. No studies have quantified the breadth of race/ethnicity representation in the AD literature. METHODS: This review identified median race/ethnicity composition of AD neuroimaging US-based research samples available as free full-text articles on PubMed. Two types of published studies were analyzed: studies that directly report race/ethnicity data (i.e., direct studies), and studies that do not report race/ethnicity but used data from a cohort study/database that does report this information (i.e., indirect studies). RESULTS: Direct studies (n = 719) have median representation of 88.9% white or 87.4% Non-Hispanic white, 7.3% Black/African American, and 3.4% Hispanic/Latino ethnicity, with 0% Asian American, Native Hawaiian/Pacific Islander, and American Indian/Alaska Native, Multiracial, and Other Race participants. Cohort studies/databases (n = 44) from which indirect studies (n = 1745) derived are more diverse, with median representation of 84.2% white, 83.7% Non-Hispanic white, 11.6% Black/African American, 4.7% Hispanic/Latino, and 1.75% Asian American participants. Notably, 94% of indirect studies derive from just 10 cohort studies/databases. Comparisons of two time periods using a median split for publication year, 1994-2017 and 2018-2022, indicate that sample diversity has improved recently, particularly for Black/African American participants (3.39% from 1994-2017 and 8.29% from 2018-2022). CONCLUSIONS: There is still underrepresentation of all minoritized groups relative to Census data, especially for Hispanic/Latino and Asian American individuals. The AD neuroimaging literature will benefit from increased representative recruitment of ethnic/racial minorities. More transparent reporting of race/ethnicity data is needed.
Members of some racial and ethnic minority groups in the USA are more likely to develop Alzheimer's Disease than white people. However, they are often not included in research studies of Alzheimer's Disease. We looked at the race/ethnicity composition of people evaluated in papers published describing Alzheimer's Disease research studies based in the USA that used images of the brain. We found that all racial/ethnic minority groups were underrepresented in Alzheimer's Disease research studies, especially Hispanic/Latino and Asian American individuals. It is important that studies include representatives of all populations both for the health of those populations and improved understanding of Alzheimer's Disease in all people. Such studies should also improve efforts to understand and address racial/ethnic disparities in Alzheimer's Disease diagnosis and treatment.
RESUMEN
BACKGROUND AND AIMS: The INTRO-HCV randomized controlled trial conducted in Norway over 2017-2019 found that integrated treatment, compared with standard-of-care hospital treatment, for hepatitis C virus (HCV) with direct-acting antivirals (DAAs) improved treatment outcomes among people who inject drugs (PWID). We evaluated cost-effectiveness of the INTRO-HCV intervention. DESIGN: A Markov health state transition model of HCV disease progression and treatment with cost-effectiveness analysis from the health-provider perspective. Primary cost, utility, and health outcome data were derived from the trial. Costs and health benefits (quality-adjusted life-years, QALYs) were tracked over 50 years. Probabilistic and univariate sensitivity analyses investigated DAA price reductions and variations in HCV treatment and disease care cost assumptions, using costs from different countries (Norway, United Kingdom, United States, France, Australia). SETTING AND PARTICIPANTS: PWID attending community-based drug treatment centers for people with opioid dependence in Norway. MEASUREMENTS: Incremental cost-effectiveness ratio (ICER) in terms of cost per QALY gained, compared against a conventional (70 000/QALY) willingness-to-pay threshold for Norway and lower (20 000/QALY) threshold common among high-income countries. FINDINGS: Integrated treatment resulted in an ICER of 13 300/QALY gained, with 99% and 71% probability of being cost-effective against conventional and lower willingness-to-pay thresholds, respectively. A 30% lower DAA price reduced the ICER to 6 900/QALY gained, with 91% probability of being cost-effective at the lower willingness-to-pay threshold. A 60% and 90% lower DAA price had 36% and >99% probability of being cost-saving, respectively. Sensitivity analyses suggest integrated treatment was cost-effective at the lower willingness-to-pay threshold (>60% probability) across different assumptions on HCV treatment and disease care costs with 30% DAA price reduction, and became cost-saving with 60%-90% price reductions. CONCLUSIONS: Integrated hepatitis C virus treatment for people who inject drugs in community settings is likely cost-effective compared with standard-of-care referral pathways in Norway and may be cost-saving in settings with particular characteristics.

BackgroundThe burden of chronic hepatitis B virus (HBV) varies across the European Union (EU) and European Economic Area (EEA).AimWe aimed to update the 2017 HBV prevalence estimates in EU/EEA countries and the United Kingdom for 2018 to 2021.MethodsWe undertook a systematic review, adding to HBV prevalence estimates from an existing (2005-2017) database. Databases were searched for original English-language research articles including HBV surface antigen prevalence estimates among the general population, pregnant women, first-time blood donors (FTB), men who have sex with men (MSM), migrants and people in prison. Country experts contributed grey literature data. Risk of bias was assessed using a quality assessment framework.FindingsThe update provided 147 new prevalence estimates across the region (updated total n = 579). Median HBV prevalence in the general population was 0.5% and the highest was 3.8% (Greece). Among FTB, the highest prevalence was 0.8% (Lithuania). Estimates among pregnant women were highest in Romania and Italy (5.1%). Among migrants, the highest estimate was 31.7% (Spain). Relative to 2017 estimates, median prevalence among pregnant women decreased by 0.5% (to 0.3%) and increased by 0.9% (to 5.8%) among migrants. Among MSM, the highest estimate was 3.4% (Croatia). Prevalence among people in prison was highest in Greece (8.3%) and the median prevalence increased by 0.6% (to 2.1%).ConclusionsThe HBV prevalence is low in the general population and confined to risk populations in most European countries with some exceptions. Screening and treatment should be targeted to people in prison and migrants.

Background: People who inject drugs (PWID) in Kachin, Myanmar, have a high HIV prevalence (>40%), but there is no data on incidence. We used HIV testing data from three harm reduction drop-in centres (DIC) in Kachin (2008-2020) to determine HIV incidence trends among PWID and associations with intervention uptake. Methods: Individuals were HIV-tested at first DIC visit and periodically thereafter, during which demographic and risk behaviour data were collected. Two DIC provided opioid agonist therapy (OAT) from 2008. Monthly DIC-level needle/syringe provision (NSP) data was available from 2012. Site-level 6-monthly NSP coverage was denoted low, high, or medium if it was below the lower quartile, above upper quartile, between these quartiles of provision levels over 2012-2020, respectively. HIV incidence was estimated by linking subsequent test records for those initially testing HIV-negative. Associations with HIV incidence were examined using Cox regression. Findings: Follow-up HIV testing data was available for 31.4% (2227) of PWID initially testing HIV-negative, with 444 incident HIV infections during 6266.5 person years (py) of follow-up. Overall HIV incidence was 7.1 per 100 py (95% confidence interval 6.5-7.8), which decreased from 19.3 (13.3-28.2) in 2008-11 to 5.2 per 100 py (4.6-5.9) in 2017-20. In the full PWID incidence dataset after adjustment for various factors, recent (≤6 weeks) injecting (aHR 1.74, 1.35-2.25) and needle sharing (aHR 2.00, 1.48-2.70) were associated with higher incidence, while longer injection careers were associated with reduced incidence (aHR 0.54, 0.34-0.86, for 2-5 yrs vs <2 yrs). In a reduced dataset including data on OAT access and NSP coverage (2012-2020 for two DIC providing OAT), being on OAT during follow-up was associated with reduced HIV incidence (aHR 0.36, 0.27-0.48, compared to never being on OAT) as was high NSP coverage (aHR 0.64, 0.48-0.84, compared to medium syringe coverage). Interpretation: Although HIV incidence is high among PWID in Kachin, data suggests it has decreased since the scale-up in harm reduction interventions. Funding: US NIH, Médecins du Monde.
RESUMEN
OBJECTIVES: This study examined the cognitive correlates of financial literacy using a comprehensive neuropsychological battery, and whether education modifies the relationship between cognition and financial literacy. METHODS: Sixty-six participants completed sociodemographic questionnaires, an assessment of financial literacy, and a neuropsychological assessment. Multiple linear regression models that controlled for age, sex, and education examined the main effects of cognitive measures that showed a significant bivariate association with financial literacy. RESULTS: After correcting for multiple comparisons, the Crystallized Composite score (p = .002) and the Picture Vocabulary test (p = .002) from the NIH Toolbox, and the Multilingual Naming Test (p > .001) from the Uniform Data Set 3 were associated with financial literacy. Contrary to our hypothesis, education did not interact with cognitive measures when considering financial literacy scores. CONCLUSIONS: Findings suggest that vocabulary knowledge and semantic memory may play an important role in financial literacy in older age. CLINICAL IMPLICATIONS: Assessing vocabulary knowledge and semantic processes may help to identify older adults with lower financial literacy skills. Additionally, financial literacy interventions may consider targeting individuals with lower vocabulary knowledge and semantic processing skills.
RESUMEN
BACKGROUND: Most people who inject drugs (PWIDs) suffer from severe fatigue, and chronic hepatitis C virus (HCV) infection may play a role in this. However, there is scarce evidence about interventions that alleviate fatigue among PWIDs. The present study investigated the effect of integrated HCV treatment on fatigue in this population compared to the effect of standard HCV treatment, adjusted for sustained virological response of the HCV treatment. METHODS: This multi-center, randomized controlled trial evaluated fatigue as a secondary outcome of integrated HCV treatment (the INTRO-HCV trial). From May 2017 to June 2019, 276 participants in Bergen and Stavanger, Norway, were randomly assigned to receive integrated and standard HCV treatment. Integrated treatment was delivered in eight decentralized outpatient opioid agonist therapy clinics and two community care centers; standard treatment was delivered in specialized infectious disease outpatient clinics at referral hospitals. Fatigue was assessed prior to treatment and 12 weeks after treatment using the nine-item Fatigue Severity Scale (FSS-9). We applied a linear mixed model to evaluate the impact of integrated HCV treatment on changes in FSS-9 (ΔFSS-9) sum scores. RESULTS: At baseline, the mean FSS-9 sum score was 46 (standard deviation (SD): 15) for participants on integrated HCV treatment and 41 (SD: 16) for those on standard treatment. Twelve weeks after completed HCV treatment, the mean FSS-9 sum score for participants receiving integrated HCV treatment was 42 (SD: 15) and 40 (SD: 14) for those receiving standard HCV treatment. Integrated HCV treatment did not reduce the FSS-9 scores compared to standard HCV treatment (ΔFSS-9: -3.0, 95% confidence interval (CI): -6.4;0.4). CONCLUSIONS: Fatigue is a common symptom among PWIDs. Integrated HCV treatment is at least equal to standard HCV treatment in improving fatigue. TRIAL REGISTRATION: ClinicalTrials.gov.no NCT03155906, 16/05/2017.

OBJECTIVES: Mycoplasma genitalium (MG) disproportionately affects men who have sex with men (MSM). We determined the cost-effectiveness of different testing strategies for MG in MSM, taking a healthcare provider perspective. METHODS: We used inputs from a dynamic transmission model of MG among MSM living in Australia in a decision tree model to evaluate the impact of four testing scenarios on MG incidence: (1) no one tested; (2) symptomatic MSM; (3) symptomatic and high-risk asymptomatic MSM; (4) all MSM. We calculated the incremental cost-effectiveness ratios (ICERs) using a willingness-to-pay threshold of $A30 000 per quality-adjusted life year (QALY) gained. We explored the impact of adding an antimicrobial resistance (AMR) tax (ie, additional cost per antibiotic consumed) to identify the threshold, whereby any testing for MG is no longer cost-effective. RESULTS: Testing only symptomatic MSM is the most cost-effective (ICER $3677 per QALY gained) approach. Offering testing to all MSM is dominated (ie, higher costs and lower QALYs gained compared with other strategies). When the AMR tax per antibiotic given was above $150, any testing for MG was no longer cost-effective. CONCLUSION: Testing only symptomatic MSM is the most cost-effective option, even when the potential costs associated with AMR are accounted for (up to $150 additional cost per antibiotic given). For pathogens like MG, where there are anticipated future costs related to AMR, we recommend models that test the impact of incorporating an AMR tax as they can change the results and conclusions of cost-effectiveness studies.

We identified key risk factors for HIV among people who inject drugs (PWID) in Pakistan and explored access to free clean needles. Multivariable logistic regression was used to investigate associations between HIV prevalence and demographic, behavioral, and socio-economic characteristics of PWID. Data came from the Government of Pakistan's Integrated Biological and Behavioral Surveillance (IBBS) Round 5 (2016-17; 14 cities). A secondary analysis investigated associations with reported access to clean needles. Unweighted HIV prevalence among 4,062 PWID (99% male) was 21.0%. Longer injecting duration (Odds ratio [OR] 1.06 [95% confidence interval: 1.02-1.10]; per year), higher injecting frequency (OR 1.67 [1.30-2.13]; per unit increase), and injecting heroin (OR 1.90 [1.11-3.25]) were positively associated with HIV prevalence. There was no association between using a used syringe at last injection and HIV. Having>10 years of education had lower odds of HIV than being illiterate (OR 0.58 [0.35-0.95]). Having a regular sexual partner (OR 0.74 [0.57-0.97]) or paying for sex with the opposite sex (OR = 0.62 [0.45-0.85]) had lower odds of HIV than not. Conversely, PWID paying a man/hijra for sex had higher odds of HIV (OR 1.20 [1.00-1.43]). Receipt of clean needles varied by city of residence (0-97% coverage), whilst PWID with knowledge of HIV service delivery programs had higher odds of receiving clean needles (OR 4.58 [3.50-5.99]). Injecting behaviors were associated with HIV prevalence among PWID, though risks related to paying for sex remain complicated. Geographical variation in access to clean needles suggests potential benefits of more widely spread public health services.
Key MessagesWhat is already known on this topicThe HIV epidemic in Pakistan is concentrated among key populations including people who inject drugs.What this study addsInjecting practices, sexual behaviors, and socio-economic factors are associated with HIV prevalence among people who inject drugs. Access to harm reduction services is varied in Pakistan.How this study might affect research, practice, or policyAccess to clean free needles, as well as service delivery programs, with a broad geographical reach remain important to curb the HIV epidemic among people who inject drugs in Pakistan.

BACKGROUND: Measuring the incidence of HIV and hepatitis C virus (HCV) infection among people who inject drugs (PWID) is key to track progress towards elimination. We aimed to summarise global data on HIV and primary HCV incidence among PWID and associations with age and sex or gender. METHODS: In this systematic review and meta-analysis, we updated an existing database of HIV and HCV incidence studies among PWID by searching MEDLINE, Embase, and PsycINFO, capturing studies published between Jan 1, 2000, and Dec 12, 2022, with no language or study design restrictions. We contacted authors of identified studies for unpublished or updated data. We included studies that estimated incidence by longitudinally re-testing people at risk of infection or by using assays for recent infection. We pooled incidence and relative risk (RR; young [generally defined as ≤25 years] vs older PWID; women vs men) estimates using random-effects meta-analysis and assessed risk of bias with a modified Newcastle-Ottawa scale. This study is registered with PROSPERO, CRD42020220884. FINDINGS: Our updated search identified 9493 publications, of which 211 were eligible for full-text review. An additional 377 full-text records from our existing database and five records identified through cross-referencing were assessed. Including 28 unpublished records, 125 records met the inclusion criteria. We identified 64 estimates of HIV incidence (30 from high-income countries [HICs] and 34 from low-income or middle-income countries [LMICs]) and 66 estimates of HCV incidence (52 from HICs and 14 from LMICs). 41 (64%) of 64 HIV and 42 (64%) of 66 HCV estimates were from single cities rather than being multi-city or nationwide. Estimates were measured over 1987-2021 for HIV and 1992-2021 for HCV. Pooled HIV incidence was 1·7 per 100 person-years (95% CI 1·3-2·3; I2=98·4%) and pooled HCV incidence was 12·1 per 100 person-years (10·0-14·6; I2=97·2%). Young PWID had a greater risk of HIV (RR 1·5, 95% CI 1·2-1·8; I2=66·9%) and HCV (1·5, 1·3-1·8; I2=70·6%) acquisition than older PWID. Women had a greater risk of HIV (RR 1·4, 95% CI 1·1-1·6; I2=55·3%) and HCV (1·2, 1·1-1·3; I2=43·3%) acquisition than men. For both HIV and HCV, the median risk-of-bias score was 6 (IQR 6-7), indicating moderate risk. INTERPRETATION: Although sparse, available HIV and HCV incidence estimates offer insights into global levels of HIV and HCV transmission among PWID. Intensified efforts are needed to keep track of the HIV and HCV epidemics among PWID and to expand access to age-appropriate and gender-appropriate prevention services that serve young PWID and women who inject drugs.

OBJECTIVES: The goal of this study was to test whether interpersonal dysfunction, characterized by loneliness and/or dissatisfaction with relationships, is an imminent predictor of financial exploitation vulnerability (FEV) among adults age 50+ within a 6-month observation period. This study also tests whether FEV prospectively predicts interpersonal dysfunction. METHODS: Twenty-six adults aged 50 or older completed a study involving baseline data collection and 13 follow-ups over 6 months. Linear mixed models were used for primary analyses. RESULTS: After adjustment for demographic, psychological and cognitive covariates, there were between-person effects of FEV and interpersonal dysfunction across follow-ups, suggesting that those with generally higher interpersonal dysfunction compared to other participants also reported greater FEV (B(SE) = 1.09(.33), p = .003). There was a within-person effect (B(SE) = .08(.03), p = .007) of elevated interpersonal dysfunction predicting greater FEV two weeks later across all follow-ups. Within-person effect of FEV was not predictive of interpersonal dysfunction (B(SE) = .25(.15), p = .10). There was also a significant effect of age (B(SE) = -.06(.02), p = .007), such that older individuals had lower FEV throughout follow-ups. CONCLUSION: Among adults age 50+, individuals with higher interpersonal dysfunction relative to others in the study reported greater FEV throughout the 6-month observation period. Increased loneliness and social dissatisfaction, relative to one's average level, predicts subsequent increases in FEV, and may be an imminent risk factor for exploitation.

BACKGROUND & AIMS: People who inject drugs (PWID) experience high incarceration rates which are associated with increased hepatitis C virus (HCV) transmission risk. We assess the importance of prison-based interventions for achieving HCV elimination among PWID in New South Wales (NSW), Australia. METHODS: A model of incarceration and HCV transmission among PWID was calibrated in a Bayesian framework to epidemiological and incarceration data from NSW, incorporating elevated HCV acquisition risk among recently released PWID. We projected the contribution of differences in transmission risk during/following incarceration to HCV transmission over 2020-2029. We estimated the past and potential future impact of prison-based opioid agonist therapy (OAT; ~33% coverage) and HCV treatment (1500 treatments in 2019 with 32.9%-83.3% among PWID) on HCV transmission. We estimated the time until HCV incidence reduces by 80% (WHO elimination target) compared to 2016 levels with or without prison-based interventions. RESULTS: Over 2020-2029, incarceration will contribute 23.0% (17.9-30.5) of new HCV infections. If prison-based interventions had not been implemented since 2010, HCV incidence in 2020 would have been 29.7% (95% credibility interval: 22.4-36.1) higher. If current prison and community HCV treatment rates continue, there is an 98.8% probability that elimination targets will be achieved by 2030, with this decreasing to 10.1% without current prison-based interventions. CONCLUSIONS: Existing prison-based interventions in NSW are critical components of strategies to reduce HCV incidence among PWID. Prison-based interventions are likely to be pivotal for achieving HCV elimination targets among PWID by 2030.

PURPOSE OF REVIEW: To describe sepsis-induced cardiomyopathy. Discuss indications and current evidence of using venoarterial extracorporeal membrane oxygenation (VA-ECMO) in setting of sepsis-induced cardiomyopathy. RECENT FINDINGS: Recent data suggests a survival benefit with the use of VA-ECMO in patients with septic shock complicated by septic-induced cardiomyopathy with severe left ventricular systolic dysfunction. VA-ECMO was associated with poor outcomes in adults with septic shock without severe systolic dysfunction. The evidence is generated from retrospective and meta-analysis of observational studies. SUMMARY: Sepsis-induced cardiomyopathy is an increasingly recognized entity characterized by reversible ventricular dysfunction in the setting of sepsis. When hypotension persists despite standard management of septic shock (e.g. adequate fluid resuscitation, vasopressors, inotropes) and there is evidence of severe cardiac systolic dysfunction and end-organ hypoperfusion, VA-ECMO should be considered as a bridge therapy to recovery. VA-ECMO should not be used for isolated vasodilatory septic shock without significant myocardial dysfunction.

BACKGROUND: The COVID-19 pandemic has exacerbated circumstances that place older adults at higher risk for abuse, neglect, and exploitation. Identifying characteristics of elder abuse during COVID-19 is critically important. This study characterized and compared elder abuse patterns across two time periods, a one-year period during the pandemic, and a corresponding one-year period prior to the start of the pandemic. METHODS: Contacts (including social media contacts, and email; all referred to as "calls" for expediency) made to the National Center on Elder Abuse (NCEA) resource line were examined for differences in types of reported elder abuse and characteristics of alleged perpetrators prior to the pandemic (Time 1; March 16, 2018 to March 15, 2019) and during the pandemic (Time 2; March 16, 2020 to March 15, 2021). Calls were examined for whether or not abuse was reported, the types of reported elder abuse, including financial, physical, sexual, emotional, and neglect, and characteristics of callers, victims, and alleged perpetrators. Chi-square tests of independence compared frequencies of elder abuse characteristics between time periods. RESULTS: In Time 1, 1401 calls were received, of which 795 calls (56.7%) described abuse. In Time 2, 1009 calls were received, of which 550 calls (54.5%) described abuse. The difference between time periods in frequency of abuse to non-abuse calls was not significant ([Formula: see text]). Time periods also did not significantly differ with regard to caller, victim, and perpetrator characteristics. Greater rates of physical abuse ([Formula: see text] and emotional abuse ([Formula: see text] were reported during Time 2 after adjustment for multiple comparisons. An increased frequency of multiple forms of abuse was also found in Time 2 compared to Time 1 ([Formula: see text]. CONCLUSIONS: Findings suggest differences in specific elder abuse subtypes and frequency of co-occurrence between subtypes between time periods, pointing to a potential increase in the severity of elder abuse during COVID-19.

Severe constipation is a frequent presentation but progression into a life-threatening acute compartment syndrome (ACS) is few and far between. This case highlights the typical physiological manifestations of ACS and the immediate benefits of correcting these physiological imbalances through the disimpaction of a massive faecaloma. Furthermore, in adult patients with a history of colonic dysmotility, adult Hirschsprung's disease should be considered.
