Adverse health outcomes in offspring of parents with alcohol-related liver disease: Nationwide Danish cohort study.

BACKGROUND: Parental drinking can cause harm to the offspring. A parent's diagnosis of alcohol-related liver disease (ALD) might be an opportunity to reach offspring with preventive interventions. We investigated offspring risk of adverse health outcomes throughout life, their association with their parent's educational level and diagnosis of ALD. METHODS AND FINDINGS: We used nationwide health registries to identify offspring of parents diagnosed with ALD in Denmark 1996 to 2018 and age- and sex-matched comparators (20:1). We estimated the incidence rate ratios (IRRs) of hospital contacts with adverse health outcomes, overall and in socioeconomic strata. We used a self-controlled design to examine whether health outcomes were more likely to occur during the first year after the parent's ALD diagnosis. The 60,804 offspring of parents with ALD had a higher incidence rate of hospital contacts from age 15 to 60 years for psychiatric disease, poisoning, fracture or injury, alcohol-specific diagnoses, other substance abuse, and of death than comparators. Associations were stronger for offspring with low compared to high socioeconomic position: The IRR for admission due to poisoning was 2.2 versus 1.0 for offspring of an ALD parent with a primary level versus a highly educated ALD parent. Offspring had an increased risk for admission with psychiatric disease and poisoning in the year after their parent's ALD diagnosis. For example, among offspring whose first hospital contact with psychiatric disease was at age 13 to 25 years, the IRR in the first year after their parent's ALD diagnosis versus at another time was 1.29 (95% CI 1.13, 1.47). Main limitation was inability to include adverse health outcomes not involving hospital contact. CONCLUSIONS: Offspring of parents with ALD had a long-lasting higher rate of health outcomes associated with poor mental health and self-harm that increased shortly after their parent's diagnosis of ALD. Offspring of parents of low educational level were particularly vulnerable. This study highlights an opportunity to reach out to offspring in connection with their parent's hospitalization with ALD.

Primary Liver Cancer Risk and Mortality in Patients With Alcohol-Related Cirrhosis in England and Denmark: Observational Cohort Studies.

INTRODUCTION: Patients with alcohol-related cirrhosis (ALD cirrhosis) have an increased risk of primary liver cancer (hepatocellular carcinoma [HCC] or intrahepatic cholangiocarcinoma [iCCA]). England recommends surveillance for HCC in these patients, while Denmark does not. METHODS: We performed an observational cohort study using the English Clinical Practice Research Datalink and the nationwide Danish healthcare registries to identify 17,110 English (2000-2016) and 22,122 Danish (1994-2022) patients with diagnosis codes of ALD cirrhosis. We computed and compared incidence rates and cumulative incidence of primary liver cancer, annual ultrasound scan rates, and mortality following diagnosis of primary liver cancer. RESULTS: The overall risk of primary liver cancer was similar in England and Denmark: 5-year risk was 2.24% (95% confidence interval 2.00-2.49) in England (iCCA 0.07%, HCC 2.16%) and 2.36% (2.15-2.57) in Denmark (iCCA 0.05%, HCC 2.30%). The annual rate of ultrasound scans per person was 0.65 (0.63-0.67) in England and 0.44 (0.42-0.46) in Denmark. The 1-year mortality after a diagnosis of primary liver cancer was 59.2% (54.4-64.0) in England and 60.9% (57.4-64.4) in Denmark. The 3-year risks of HCC in those on vs off surveillance in England were 2.3% (1.0-4.6) vs 1.5% (1.0-2.2). DISCUSSION: The risk of primary liver cancer was the same in English and Danish patients with ALD cirrhosis, and HCCs constituted 97% of primary liver cancers. Mortality with primary liver cancer was equally high in both countries. Notably, in England, where guidance recommends biannual HCC surveillance with ultrasound, patients with ALD cirrhosis were undergoing fewer than 1 ultrasound scan per year.

Genetic variation in TERT modifies the risk of hepatocellular carcinoma in alcohol-related cirrhosis: results from a genome-wide case-control study.

OBJECTIVE: Hepatocellular carcinoma (HCC) often develops in patients with alcohol-related cirrhosis at an annual risk of up to 2.5%. Some host genetic risk factors have been identified but do not account for the majority of the variance in occurrence. This study aimed to identify novel susceptibility loci for the development of HCC in people with alcohol related cirrhosis. DESIGN: Patients with alcohol-related cirrhosis and HCC (cases: n=1214) and controls without HCC (n=1866), recruited from Germany, Austria, Switzerland, Italy and the UK, were included in a two-stage genome-wide association study using a case-control design. A validation cohort of 1520 people misusing alcohol but with no evidence of liver disease was included to control for possible association effects with alcohol misuse. Genotyping was performed using the InfiniumGlobal Screening Array (V.24v2, Illumina) and the OmniExpress Array (V.24v1-0a, Illumina). RESULTS: Associations with variants rs738409 in PNPLA3 and rs58542926 in TM6SF2 previously associated with an increased risk of HCC in patients with alcohol-related cirrhosis were confirmed at genome-wide significance. A novel locus rs2242652(A) in TERT (telomerase reverse transcriptase) was also associated with a decreased risk of HCC, in the combined meta-analysis, at genome-wide significance (p=6.41×10-9, OR=0.61 (95% CI 0.52 to 0.70). This protective association remained significant after correction for sex, age, body mass index and type 2 diabetes (p=7.94×10-5, OR=0.63 (95% CI 0.50 to 0.79). Carriage of rs2242652(A) in TERT was associated with an increased leucocyte telomere length (p=2.12×10-44). CONCLUSION: This study identifies rs2242652 in TERT as a novel protective factor for HCC in patients with alcohol-related cirrhosis.

Characterizing the risk interplay between alcohol intake and body mass index on cirrhosis morbidity.

BACKGROUND AND AIMS: It is thought that alcohol intake and body mass index (BMI) interact supra-additively to modulate the risk of cirrhosis, but evidence for this phenomenon is limited. We investigated the interrelationship between alcohol and BMI on the incidence of cirrhosis morbidity for participants of the United Kingdom Biobank (UKB) study. APPROACH AND RESULTS: The primary outcome was the cumulative incidence of cirrhosis morbidity, defined as a first-time hospital admission for cirrhosis (with noncirrhosis mortality incorporated as a competing risk). All UKB participants without a previous hospital admission for cirrhosis were included in the analysis. We determined the ratio of the 10-year cumulative incidence in harmful drinkers versus safe drinkers according to BMI. We also calculated the excess cumulative incidence at 10 years for individuals with obesity and/or harmful alcohol compared to safe drinkers with a healthy BMI of 20-25.0 kg/m2 . A total of 489,285 UK Biobank participants were included, with mean of 10.7 person-years' follow-up. A total of 2070 participants developed the primary outcome, equating to a crude cumulative incidence of 0.36% at 10 years (95% CI:0.34-0.38). The 10-year cumulative incidence was 8.6 times higher for harmful (1.38%) versus safe drinkers (0.16%) if BMI was healthy. Conversely, it was only 3.6 times higher for obese participants (1.99% vs. 0.56%). Excess cumulative incidence was 1.22% (95% CI:0.89-1.55) for harmful drinkers with a healthy BMI, 0.40% (95% CI:0.34-0.46) for obese individuals drinking at safe levels, and 1.83% (95% CI:1.46-2.20) for obese harmful drinkers (all compared to safe drinkers with a healthy BMI). CONCLUSIONS: Alcohol intake and obesity are independent risk factors for cirrhosis morbidity, but they do not interact supra-additively to modulate the cumulative incidence of this outcome.

Application and Extension of the Alcohol Recovery Narratives Conceptual Framework.

Recovery narratives are personal stories of health problems and recovery. A systematic review proposed a conceptual framework characterising alcohol misuse recovery narratives, consisting of eight principal dimensions, each with types and subtypes. The current study aims to apply and extend this preliminary conceptual framework. Semi-structured interviews were conducted to collect alcohol misuse recovery narratives from adult participants. A two-stage inductive and deductive thematic analysis approach was used to assess the relevance of the dimensions and types included in the preliminary conceptual framework and identify new components. The sample consisted of 11 participants from diverse socioeconomic backgrounds who had previously displayed varying degrees of alcohol misuse. All conceptual framework dimensions (genre, identity, recovery setting, drinking trajectories, drinking behaviours and traits, stages, spirituality and religion, and recovery experience) were present in the collected narratives. Three dimensions were extended by adding types and subtypes. Whilst the existing conceptual framework fitted the collected narratives, a new dimension describing the alcohol environment was required to fully characterise narratives. Types included in the alcohol environment dimension were policy and practice and social dynamics. The extended framework could guide the production of resources enabling clinicians to engage with narratives shared by their clients.

Relationship Between Anxiety, Depression, and Susceptibility to Severe Acute Respiratory Syndrome Coronavirus 2 Infection: Proof of Concept.

BACKGROUND: Psychological factors can influence susceptibility to viral infections. We examined whether such influences are evident in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: Participants (n = 102) completed measures of anxiety, depression, positive mood, and loneliness and provided a blood sample for the measurement of antibodies to the SARS-CoV-2 spike and nucleocapsid proteins. RESULTS: SARS-CoV-2 was significantly negatively associated with anxiety and depression. The model remained significant after adjustment for age and gender, although anxiety and depression were no longer significant independent predictors. CONCLUSIONS: These findings offer early support for the hypothesis that psychological factors may influence susceptibility to SARS-CoV-2 infection.

Predicting Need for Escalation of Care or Death From Repeated Daily Clinical Observations and Laboratory Results in Patients With Severe Acute Respiratory Syndrome Coronavirus 2.

We compared the performance of prognostic tools for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using parameters fitted either at the time of hospital admission or across all time points of an admission. This cohort study used clinical data to model the dynamic change in prognosis of SARS-CoV-2 at a single hospital center in the United Kingdom, including all patients admitted from February 1, 2020, to December 31, 2020, and then followed up for 60 days for intensive care unit (ICU) admission, death, or discharge from the hospital. We incorporated clinical observations and blood tests into 2 time-varying Cox proportional hazards models predicting daily 24- to 48-hour risk of admission to the ICU for those eligible for escalation of care or death for those ineligible for escalation. In developing the model, 491 patients were eligible for ICU escalation and 769 were ineligible for escalation. Our model had good discrimination of daily risk of ICU admission in the validation cohort (n = 1,141; C statistic: C = 0.91, 95% confidence interval: 0.89, 0.94) and our score performed better than other scores (National Early Warning Score 2, International Severe Acute Respiratory and Emerging Infection Comprehensive Clinical Characterisation Collaboration score) calculated using only parameters measured on admission, but it overestimated the risk of escalation (calibration slope = 0.7). A bespoke daily SARS-CoV-2 escalation risk prediction score can predict the need for clinical escalation better than a generic early warning score or a single estimation of risk calculated at admission.

Performance of routine risk scores for predicting cirrhosis-related morbidity in the community.

BACKGROUND & AIMS: Models predicting an individual's 10-year risk of cirrhosis complications have not been developed for a community setting. Our objectives were to assess the performance of existing risk scores - both with and without genetic data - for predicting cirrhosis complications in the community. METHODS: We used a 2-stage study design. In stage 1, a systematic review was conducted to identify risk scores derived from routine liver blood tests that have demonstrated prior ability to predict cirrhosis-related complication events. Risk scores identified from stage 1 were tested in a UK Biobank subgroup, comprising participants with a risk factor for chronic liver disease (stage 2). Cirrhosis complications were defined as hospitalisation for liver cirrhosis or presentation with hepatocellular carcinoma. Discrimination of risk scores with and without genetic data was assessed using the Wolbers C-index, Harrell's adequacy index, and cumulative incidence curves. RESULTS: Twenty risk scores were identified from the stage-1 systematic review. For stage-2, 197,509 UK biobank participants were selected. The cumulative incidence of cirrhosis complications at 10 years was 0.58%; 95% CI 0.54-0.61 (1,110 events). The top performing risk scores were aspartate aminotransferase-to-platelet ratio index (APRI: C-index 0.804; 95% CI 0.788-0.820) and fibrosis-4 index (FIB-4: C-index 0.780; 95% CI 0.764-0.795). The 10-year cumulative incidences of cirrhosis complications for participants with an APRI score exceeding the 90th, 95th and 99th percentile were 3.30%, 5.42% and 14.83%, respectively. Inclusion of established genetic risk loci associated with cirrhosis added <5% of new prognostic information to the APRI score and improved the C-index only minimally (i.e. from 0.804 to 0.809). CONCLUSIONS: Accessible risk scores derived from routine blood tests (particularly APRI and FIB-4) can be repurposed to estimate 10-year risk of cirrhosis morbidity in the community. Genetic data improves performance only minimally. LAY SUMMARY: New approaches are needed in community settings to reduce the late diagnosis of chronic liver disease. Thus, in a community cohort, we assessed the ability of 20 routine risk scores to predict 10-year risk of cirrhosis-related complications. We show that 2 routine risk scores in particular - "APRI" and "FIB-4" - could be repurposed to estimate an individual's 10-year risk of cirrhosis-related morbidity. Adding genetic risk factor information to these scores only modestly improved performance.

Chest Radiograph Scoring Alone or Combined with Other Risk Scores for Predicting Outcomes in COVID-19.

Background Radiographic severity may help predict patient deterioration and outcomes from COVID-19 pneumonia. Purpose To assess the reliability and reproducibility of three chest radiograph reporting systems (radiographic assessment of lung edema [RALE], Brixia, and percentage opacification) in patients with proven SARS-CoV-2 infection and examine the ability of these scores to predict adverse outcomes both alone and in conjunction with two clinical scoring systems, National Early Warning Score 2 (NEWS2) and International Severe Acute Respiratory and Emerging Infection Consortium: Coronavirus Clinical Characterization Consortium (ISARIC-4C) mortality. Materials and Methods This retrospective cohort study used routinely collected clinical data of patients with polymerase chain reaction-positive SARS-CoV-2 infection admitted to a single center from February 2020 through July 2020. Initial chest radiographs were scored for RALE, Brixia, and percentage opacification by one of three radiologists. Intra- and interreader agreement were assessed with intraclass correlation coefficients. The rate of admission to the intensive care unit (ICU) or death up to 60 days after scored chest radiograph was estimated. NEWS2 and ISARIC-4C mortality at hospital admission were calculated. Daily risk for admission to ICU or death was modeled with Cox proportional hazards models that incorporated the chest radiograph scores adjusted for NEWS2 or ISARIC-4C mortality. Results Admission chest radiographs of 50 patients (mean age, 74 years ± 16 [standard deviation]; 28 men) were scored by all three radiologists, with good interreader reliability for all scores, as follows: intraclass correlation coefficients were 0.87 for RALE (95% CI: 0.80, 0.92), 0.86 for Brixia (95% CI: 0.76, 0.92), and 0.72 for percentage opacification (95% CI: 0.48, 0.85). Of 751 patients with a chest radiograph, those with greater than 75% opacification had a median time to ICU admission or death of just 1-2 days. Among 628 patients for whom data were available (median age, 76 years [interquartile range, 61-84 years]; 344 men), opacification of 51%-75% increased risk for ICU admission or death by twofold (hazard ratio, 2.2; 95% CI: 1.6, 2.8), and opacification greater than 75% increased ICU risk by fourfold (hazard ratio, 4.0; 95% CI: 3.4, 4.7) compared with opacification of 0%-25%, when adjusted for NEWS2 score. Conclusion Brixia, radiographic assessment of lung edema, and percentage opacification scores all reliably helped predict adverse outcomes in SARS-CoV-2 infection. © RSNA, 2021 Online supplemental material is available for this article.

The Effect of Covid-19 on Alcohol Use Disorder and the Role of Universal Alcohol Screening in an Inpatient Setting: A Retrospective Cohort Control Study.

AIM: To assess the impact of Covid-19 on alcohol use disorders (AUD) and the role of universal alcohol screening (UAS) in an inpatient setting. METHODS: Retrospective cohorts were defined as pre-pandemic and pandemic admitted to Nottingham University Hospitals (April to October; 2019 and 2020) and had alcohol assessment by AUDIT-C. AUDIT-C score was assessed against age, sex, ethnicity, admission type, speciality and primary diagnosis of mental disorders. Subgroup analysis for Covid-19 positive patients was performed. RESULTS: A total of 63,927 admissions (47,954 patients) were included. The pandemic period compared to pre-pandemic had fewer overall admissions (27,349 vs 36,578, P < 0.001), fewer with AUD (17.6% vs 18.4%, P = 0.008) but a higher proportion of alcohol dependents (3.7% vs 3.0%, P < 0.0001). In the pandemic those with AUD were more likely to be male (P = 0.003), white (P < 0.001), in relationship (P < 0.001), of higher socioeconomic background (P < 0.001), have alcohol-related mental disorders (P = 0.002), emergency admission (P < 0.001), medical speciality admission (P < 0.001) and shorter length of stay (P < 0.033) compared to pre-pandemic AUD. Covid-19 positive patients with concomitant AUD died at younger age (P < 0.05) than Covid-19 positive patients at low risk for AUD. CONCLUSIONS: The pandemic changed the characteristics of inpatients with AUD. There was a higher proportion of alcohol-dependent admissions with evidence that a younger, less deprived group have been significantly impacted. UAS provides a useful tool to screen for AUD and to identify the change when facing sudden health crises.

Genome-Wide Association Study for Alcohol-Related Cirrhosis Identifies Risk Loci in MARC1 and HNRNPUL1.

BACKGROUND AND AIMS: Little is known about genetic factors that affect development of alcohol-related cirrhosis. We performed a genome-wide association study (GWAS) of samples from the United Kingdom Biobank (UKB) to identify polymorphisms associated with risk of alcohol-related liver disease. METHODS: We performed a GWAS of 35,839 participants in the UKB with high intake of alcohol against markers of hepatic fibrosis (FIB-4, APRI, and Forns index scores) and hepatocellular injury (levels of aminotransferases). Loci identified in the discovery analysis were tested for their association with alcohol-related cirrhosis in 3 separate European cohorts (phase 1 validation cohort; n=2545). Variants associated with alcohol-related cirrhosis in the validation at a false discovery rate of less than 20% were then directly genotyped in 2 additional European validation cohorts (phase 2 validation, n=2068). RESULTS: In the GWAS of the discovery cohort, we identified 50 independent risk loci with genome-wide significance (P < 5 × 10-8). Nine of these loci were significantly associated with alcohol-related cirrhosis in the phase 1 validation cohort; 6 of these 9 loci were significantly associated with alcohol-related cirrhosis in phase 2 validation cohort, at a false discovery rate below 5%. The loci included variants in the mitochondrial amidoxime reducing component 1 gene (MARC1) and the heterogeneous nuclear ribonucleoprotein U like 1 gene (HNRNPUL1). After we adjusted for age, sex, body mass index, and type-2 diabetes in the phase 2 validation cohort, the minor A allele of MARC1:rs2642438 was associated with reduced risk of alcohol-related cirrhosis (adjusted odds ratio, 0.76; P=.0027); conversely, the minor C allele of HNRNPUL1:rs15052 was associated with an increased risk of alcohol-related cirrhosis (adjusted odds ratio, 1.30; P=.020). CONCLUSIONS: In a GWAS of samples from the UKB, we identified and validated (in 5 European cohorts) single-nucleotide polymorphisms that affect risk of alcohol-related cirrhosis in opposite directions: the minor A allele in MARC1:rs2642438 decreases risk, whereas the minor C allele in HNRNPUL1:rs15052 increases risk.

Choice of faecal immunochemical test matters: comparison of OC-Sensor and HM-JACKarc, in the assessment of patients at high risk of colorectal cancer.

OBJECTIVES: Currently, NICE recommends the use of faecal immunochemical test (FIT) at faecal haemoglobin concentrations (f-Hb) of 10 µg Hb/g faeces to stratify for colorectal cancer (CRC) risk in symptomatic populations. This f-Hb cut-off is advised across all analysers, despite the fact that a direct comparison of analyser performance, in a clinical setting, has not been performed. METHODS: Two specimen collection devices (OC-Sensor, OC-S; HM-JACKarc, HM-J) were sent to 914 consecutive individuals referred for follow up due to their increased risk of CRC. Agreement of f-Hb around cut-offs of 4, 10 and 150 µg Hb/g faeces and CRC detection rates were assessed. Two OC-S devices were sent to a further 114 individuals, for within test comparisons. RESULTS: A total of 732 (80.1%) individuals correctly completed and returned two different FIT devices, with 38 (5.2%) CRCs detected. Median f-Hb for individuals diagnosed with and without CRC were 258.5 and 1.8 µg Hb/g faeces for OC-S and 318.1 and 1.0 µg Hb/g faeces for HM-J respectively. Correlation of f-Hb results between OC-S/HM-J over the full range was rho=0.74, p<0.001. Using a f-Hb of 4 µg Hb/g faeces for both tests found an agreement of 88.1%, at 10 µg Hb/g faeces 91.7% and at 150 µg Hb/g faeces 96.3%. A total of 114 individuals completed and returned two OC-S devices; correlation across the full range was rho=0.98, p<0.001. CONCLUSIONS: We found large variations in f-Hb when different FIT devices were used, but a smaller variation when the same FIT device was used. Our data suggest that analyser-specific f-Hb cut-offs are applied with regard to clinical decision making, especially at lower f-Hb.

Does Advice Based on Biomarkers of Liver Injury or Non-Invasive Tests of Liver Fibrosis Impact High-Risk Drinking Behaviour: A Systematic Review With Meta-analysis.

BACKGROUND AND AIMS: Alcohol dependence affects over 240 million people worldwide and attributed to 3 million deaths annually. Early identification and intervention are key to prevent harm. We aim to systematically review literature on the effectiveness of adding advice based on biomarkers of liver injury or non-invasive tests of liver fibrosis (intervention-based advice) to prevent alcohol misuse. METHODS: Electronic search was conducted on Ovid Medline, PubMed, EMBASE, Psychinfo and CINAHL for articles published up to end of February 2020. Additionally, we searched study citations, Scopus, Ethos and Clinical trials. The primary outcome measure was changed in self-reported alcohol consumption analysed by random-effects meta-analysis. Secondary outcomes included change to liver blood markers and alcohol-related health outcomes. RESULTS: Fourteen randomized controlled trials (RCTs) and two observational studies comprising n = 3763 participants were included. Meta-analyses showed a greater reduction in alcohol consumption and liver biomarkers for the intervention compared to control group: mean difference for weekly alcohol intake was -74.4 g/week (95% confidence interval (CI) -126.1, -22.6, P = 0.005) and mean difference for gamma-glutamyl transferase (GGT) -19.7 IU/l (95% CI -33.1, -6.4, P = 0.004). There was a higher incidence of alcohol-attributed mortality, number of days spent in the hospital, physician visits and sickness absence in the non-intervention group. The quality of the included studies was moderate for RCTs and high for observational studies. CONCLUSIONS: The review confirmed a significant association between the addition of intervention-based advice in routine care to the reduction of harmful alcohol consumption, GGT and alcohol-related mortality. The findings support the inclusion of this type of advice in routine alcohol care.

Non-invasive risk scores do not reliably identify future cirrhosis or hepatocellular carcinoma in Type 2 diabetes: The Edinburgh type 2 diabetes study.

BACKGROUND: The incidence of cirrhosis and hepatocellular carcinoma (HCC) is increased in Type 2 diabetes, primarily secondary to non-alcoholic fatty liver disease (NAFLD). European guidelines recommend screening for NAFLD in Type 2 diabetes. American guidelines, while not advocating a screening protocol, suggest using non-invasive markers of fibrosis for risk-stratification and guiding onward referral. AIMS: To test the ability of individual fibrosis scores and the European screening algorithm to predict 11-year incident cirrhosis/HCC in an asymptomatic community cohort of older people with Type 2 diabetes. METHODS: The Edinburgh Type 2 Diabetes Study investigated men and women with Type 2 diabetes (n = 1066, aged 60-75 at baseline). Liver markers were measured at baseline and year 1; steatosis and fibrosis markers were calculated according to independently published calculations. During 11 years of follow-up, cases of cirrhosis and HCC were identified. RESULTS: Forty-three out of 1059 participants with no baseline cirrhosis/HCC developed incident disease. All scores were significantly associated with incident liver disease by odds ratio (P < .05). The ability of the risk-stratification tools to accurately identify those who developed incident cirrhosis/HCC was poor with low-positive predictive values (5-46%) and high false-negative and -positive rates (up to 60% and 77%) respectively. When fibrosis risk scores were used in conjunction with the European algorithm, they performed modestly better than when applied in isolation. CONCLUSIONS: In a cohort with a moderately low incidence of cirrhosis/HCC, existing risk scores did not reliably identify participants at high risk. Better prediction models for cirrhosis/HCC in people with Type 2 diabetes are required.

Young people, mental health and COVID-19 infection: the canaries we put in the coal mine.

OBJECTIVES: The number of people testing positive for Severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) in the UK, particularly among young adults, is increasing. We report here on the mental health of young adults and related psychological and behavioural responses to the pandemic and consider the role of these factors in fuelling the increase in coronavirus disease 2019 (COVID-19) in this group. METHODS: An online survey was completed during the first six weeks of the first UK-wide lockdown by 3097 respondents, including data for 364 respondents aged 18-24 years. The survey included measures of mental health and indices capturing related psychological and behavioural responses to the pandemic. RESULTS: The mental health of 18- to 24-years-olds in the first 6 weeks of lockdown was significantly poorer than that of older respondents and previously published norms: with 84% reporting symptoms of depression and 72% reporting symptoms of anxiety. Young adults also reported significantly greater loneliness and reduced positive mood, both of which were also associated with greater mental health difficulties. CONCLUSIONS: We contend that the combination of mental health, social and economic considerations may have contributed to the rise of COVID-19 infections in young adults, and ascribing blame to this group will not aid our efforts to regain control of the disease.

Adverse events after first, single, mesh and non-mesh surgical procedures for stress urinary incontinence and pelvic organ prolapse in Scotland, 1997-2016: a population-based cohort study.

BACKGROUND: Concerns have been raised about the safety of surgery for stress urinary incontinence and pelvic organ prolapse using transvaginal mesh. We assessed adverse outcomes after first, single mesh procedures and comparable non-mesh procedures. METHODS: We did a cohort study of women in Scotland aged 20 years or older undergoing a first, single incontinence procedure or prolapse procedure during 1997-98 to 2015-16 identified from a national hospital admission database. Primary outcomes were immediate postoperative complications and subsequent (within 5 years) readmissions for later postoperative complications, further incontinence surgery, or further prolapse surgery. Poisson regression models were used to compare outcomes after procedures carried out with and without mesh. FINDINGS: Between April 1, 1997, and March 31, 2016, 16 660 women underwent a first, single incontinence procedure, 13 133 (79%) of which used mesh. Compared with non-mesh open surgery (colposuspension), mesh procedures had a lower risk of immediate complications (adjusted relative risk [aRR] 0·44 [95% CI 0·36-0·55]) and subsequent prolapse surgery (adjusted incidence rate ratio [aIRR] 0·30 [0·24-0·39]), and a similar risk of further incontinence surgery (0·90 [0·73-1·11]) and later complications (1·12 [0·98-1·27]); all ratios are for retropubic mesh. During the same time period, 18 986 women underwent a first, single prolapse procedure, 1279 (7%) of which used mesh. Compared with non-mesh repair, mesh repair of anterior compartment prolapse was associated with a similar risk of immediate complications (aRR 0·93 [95% CI 0·49-1·79]); an increased risk of further incontinence (aIRR 3·20 [2·06-4·96]) and prolapse surgery (1·69 [1·29-2·20]); and a substantially increased risk of later complications (3·15 [2·46-4·04]). Compared with non-mesh repair, mesh repair of posterior compartment prolapse was associated with a similarly increased risk of repeat prolapse surgery and later complications. No difference in any outcome was observed between vaginal and, separately, abdominal mesh repair of vaginal vault prolapse compared with vaginal non-mesh repair. INTERPRETATION: Our results support the use of mesh procedures for incontinence, although further research on longer term outcomes would be beneficial. Mesh procedures for anterior and posterior compartment prolapse cannot be recommended for primary prolapse repair. Both vaginal and abdominal mesh procedures for vaginal vault prolapse repair are associated with similar effectiveness and complication rates to non-mesh vaginal repair. These results therefore do not clearly favour any particular vault repair procedure. FUNDING: None.

Rutosides for prevention of post-thrombotic syndrome.

BACKGROUND: Post-thrombotic syndrome (PTS) is a long-term complication of deep venous thrombosis (DVT) that is characterised by pain, swelling, and skin changes in the affected limb. One in three patients with DVT will develop post-thrombotic sequelae within five years. The current standard care for the prevention of PTS following DVT is elastic compression stockings. Rutosides are a group of compounds derived from horse chestnut (Aesculus hippocastanum), a traditional herbal remedy for treating oedema formation in chronic venous insufficiency (CVI). However, it is not known whether rutosides are effective and safe in the prevention of PTS. This is the second update of the review first published in 2013. OBJECTIVES: To determine the effectiveness and safety of rutosides for prevention of post-thrombotic syndrome (PTS) in patients with deep vein thrombosis (DVT), compared to placebo, no intervention, or reference medication. SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 21 August 2018. SELECTION CRITERIA: We planned to include trials of rutosides versus any alternative (placebo, no intervention, or reference medication) in the prevention of PTS in patients with DVT. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion and intended to extract information from the trials. MAIN RESULTS: No studies were identified comparing rutosides versus any alternative in the prevention of PTS. AUTHORS' CONCLUSIONS: As there were no studies identified in this review there is currently insufficient evidence to determine the effectiveness and safety of rutosides for prevention of PTS in patients with DVT. Some studies suggest that rutosides may provide short-term relief of PTS symptoms. However, there is nothing published on their use as a preventative therapy for PTS. High quality randomised controlled trials of rutoside versus any alternative are required to build the evidence base in this area.

Rutosides for treatment of post-thrombotic syndrome.

BACKGROUND: Post-thrombotic syndrome (PTS) is a long-term complication of deep venous thrombosis (DVT) that is characterised by pain, swelling, and skin changes in the affected limb. One in three patients with DVT will develop post-thrombotic sequelae within five years. Rutosides are a group of compounds derived from horse chestnut (Aesculus hippocastanum), a traditional herbal remedy for treating oedema formation in chronic venous insufficiency (CVI). However, it is not known whether rutosides are effective and safe in the treatment of PTS. This is the second update of the review first published in 2013. OBJECTIVES: To determine the effectiveness (improvement or deterioration in symptoms) and safety of rutosides for treatment of post-thrombotic syndrome (PTS) in patients with DVT compared to placebo, no intervention, elastic compression stockings (ECS) or any other treatment. SEARCH METHODS: The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases and World Health Organization International Clinical Trials Registry Platform and ClinicalTrials.gov trials registers to 21 August 2018. SELECTION CRITERIA: Two review authors independently assessed studies for inclusion. Studies were included to allow the comparison of rutosides versus placebo or no treatment, rutosides versus ECS, and rutosides versus any other treatment. Two review authors extracted information from the trials. Disagreements were resolved by discussion. DATA COLLECTION AND ANALYSIS: Data were extracted using designated data extraction forms. The Cochrane 'Risk of bias' tool was used for all included studies to assist in the assessment of quality. Primary outcome measures were the occurrence of leg ulceration over time (yes or no) and any improvement or deterioration of post-thrombotic syndrome (yes or no). Secondary outcomes included reduction of oedema, pain, recurrence of DVT or pulmonary embolism, compliance with therapy, and adverse effects. All of the outcome measures were analysed using Mantel-Haenzel fixed-effect model odds ratios. The unit of analysis was the number of patients. We used GRADE to assess the quality of the evidence for each outcome. MAIN RESULTS: Ten reports of nine studies were identified following searching and three studies with a total of 233 participants met the inclusion criteria. Overall quality of evidence using the GRADE approach was low, predominantly due to the lack of both participant and researcher blinding in the included studies. The quality of the evidence was further limited as only three small studies contributed to the review findings. A subjective scoring system was used to obtain the symptoms of PTS so it was important that the assessors were blinded to the intervention. One study compared rutosides with placebo, one study compared rutosides with ECS and rutosides plus ECS versus ECS alone, and one study compared rutosides with an alternative venoactive remedy. Occurrence of leg ulceration was not reported in any of the included studies. There was no clear evidence to support a difference in PTS improvement between the rutosides or placebo/no treatment groups (OR 1.29, 95% CI 0.69 to 2.41; 164 participants; 2 studies; low-quality evidence); or between the rutosides and ECS groups (OR 0.80, 95% CI 0.31 to 2.03; 80 participants; 1 study ; low-quality evidence). Results from one small study reported less PTS improvement in the rutosides group compared to an alternative venoactive remedy (OR 0.18, 95% CI 0.04 to 0.94; 29 participants; 1 study; low-quality evidence). There was no clear evidence to support a difference in PTS deterioration when comparing rutosides with placebo/no treatment (OR 0.61, 95% CI 0.19 to 1.90; 80 participants; 1 study); with ECS (OR 0.61, 95% CI 0.19 to 1.90; 80 participants; 1 study); or an alternative venoactive remedy (OR 0.19, 95% CI 0.01 to 4.24; 29 participants; 1 study). No clear evidence of a difference in adverse effects between the rutosides and placebo/no treatment groups was seen ('mild side effects' reported in 7/41 and 5/42 respectively). In the study comparing rutosides with ECS, 2/80 could not tolerate ECS and 6/80 stopped medication due to side effects. The study comparing rutosides with an alternative venoactive remedy did not comment on side effects AUTHORS' CONCLUSIONS: There was no evidence that rutosides were superior to the use of placebo or ECS. Overall, there is currently limited low-quality evidence that 'venoactive' or 'phlebotonic' remedies such as rutosides reduce symptoms of PTS. Mild side effects were noted in one study. The three studies included in this review provide no evidence to support the use of rutosides in the treatment of PTS.
