The Liverpool alcohol-related liver disease algorithm identifies twice as many emergency admissions compared to standard methods when applied to Hospital Episode Statistics for England. Aliment Pharmacol Ther 2023; 57:368-377. [PMID: 36397658 PMCID: PMC10099257 DOI: 10.1111/apt.17307] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/29/2022] [Revised: 05/19/2022] [Accepted: 11/03/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND Emergency admissions in England for alcohol-related liver disease (ArLD) have increased steadily for decades. Statistics based on administrative data typically focus on the ArLD-specific code as the primary diagnosis and are therefore at risk of excluding ArLD admissions defined by other coding combinations. AIM To deploy the Liverpool ArLD Algorithm (LAA), which accounts for alternative coding patterns (e.g., ArLD secondary diagnosis with alcohol/liver-related primary diagnosis), to national and local datasets in the context of studying trends in ArLD admissions before and during the COVID-19 pandemic. METHODS We applied the standard approach and LAA to Hospital Episode Statistics for England (2013-21). The algorithm was also deployed at 28 hospitals to discharge coding for emergency admissions during a common 7-day period in 2019 and 2020, in which eligible patient records were reviewed manually to verify the diagnosis and extract data. RESULTS Nationally, LAA identified approximately 100% more monthly emergency admissions from 2013 to 2021 than the standard method. The annual number of ArLD-specific admissions increased by 30.4%. Of 39,667 admissions in 2020/21, only 19,949 were identified with standard approach, an estimated admission cost of £70 million in under-recorded cases. Within 28 local hospital datasets, 233 admissions were identified using the standard approach and a further 250 locally verified cases using the LAA (107% uplift). There was an 18% absolute increase in ArLD admissions in the seven-day evaluation period in 2020 versus 2019. There were no differences in disease severity or mortality, or in the proportion of admissions with decompensation of cirrhosis or alcoholic hepatitis. CONCLUSIONS The LAA can be applied successfully to local and national datasets. It consistently identifies approximately 100% more cases than the standard coding approach. The algorithm has revealed the true extent of ArLD admissions. The pandemic has compounded a long-term rise in ArLD admissions and mortality.

Abstract
Abstract
Background
Prognosis in light chain (AL) amyloidosis is largely determined by the severity of cardiac involvement. Conventional (Mayo) staging includes 1) hs troponin 2) N-terminal pro-beta natriuretic peptide (NT-pro BNP) and 3)free light chain difference.
Methods
In a retrospective study of 75 AL amyloidosis patients referred to a quaternary amyloid clinic, all patients underwent comprehensive echocardiographic assessment. Echocardiographic parameters included left ventricular (LV) ejection fraction, LV mass, diastolic function, global longitudinal strain (GLS) and indexed left atrial volume (LAVI). Mortality was assessed through review of clinical records.
Results
Over a median follow up of 51 months, 29/75 (39%) of patients died. LAVI, E/e', e', LVGLS, were univariate predictors of mortality (p<0.1). LAVI was the only independent echocardiographic predictor in a multivariable model. Kaplan Meir analysis evaluated LAVI, LVGLS and E/e' using clinical cutoffs as a predictor of survival; only LAVI and LVGLS were significant. A novel “Echo score” comprising of LAVI (>42 ml/m2) and LVGLS (<−12%) was a predictor of mortality with similar prognostic performance as Mayo stage. (Echo score AUC 0.745, 95% CI 0.64–0.85 vs Mayo score AUC 0.752 95% CI 0.66–0.86, p=0.9).
Conclusion
LAVI, a simple, echocardiographic parameter was as an independent predictor of mortality in AL amyloidosis. A composite echocardiographic score combining LAVI and LVGLS stratified AL-amyloidosis patients into 3 distinct groups with similar prognostic power as Mayo stage for all-cause mortality.

Abstract
Epidemiological data on hepatitis B virus (HBV) are needed to benchmark HBV elimination goals. We recently assessed prevalence of HBV infection and determinants in participants attending the Emergency Department in Paramaribo, Suriname, South America. Overall, 24.5% (95%CI = 22.7-26.4%) of participants had anti-Hepatitis B core antibodies, which was associated with older age (per year, adjusted Odds Ratio [aOR] = 1.03, 95%CI = 1.02-1.04), Afro-Surinamese (aOR = 1.84, 95%CI = 1.52-2.19) and Javanese ethnicity (aOR = 1.63, 95%CI = 1.28-2.07, compared to the grand mean). 3.2% of participants were Hepatitis B surface Ag-positive, which was also associated with older age (per year, aOR = 1.02, 95%CI = 1.00-1.04), Javanese (aOR = 4.3, 95%CI = 2.66-6.95) and Afro-Surinamese ethnicity (aOR = 2.36, 95%CI = 1.51-3.71). Sex, nosocomial or culturally-related HBV transmission risk-factors were not associated with infection. Phylogenetic analysis revealed strong ethnic clustering: Indonesian subgenotype HBV/B3 among Javanese and African subgenotypes HBV/A1, HBV/QS-A3 and HBV/E among Afro-Surinamese. Testing for HBV during adulthood should be considered for individuals living in Suriname, specifically with Javanese and Afro-Surinamese ancestry.

Abstract
The widespread availability of high-dimensional electronic healthcare record (EHR) datasets has led to significant interest in using such data to derive clinical insights and make risk predictions. More specifically, techniques from machine learning are being increasingly applied to the problem of dynamic survival analysis, where updated time-to-event risk predictions are learned as a function of the full covariate trajectory from EHR datasets. EHR data presents unique challenges in the context of dynamic survival analysis, involving a variety of decisions about data representation, modeling, interpretability, and clinically meaningful evaluation. In this paper we propose a new approach to dynamic survival analysis which addresses some of these challenges. Our modeling approach is based on learning a global parametric distribution to represent population characteristics and then dynamically locating individuals on the time-axis of this distribution conditioned on their histories. For evaluation we also propose a new version of the dynamic C-Index for clinically meaningful evaluation of dynamic survival models. To validate our approach we conduct dynamic risk prediction on three real-world datasets, involving COVID-19 severe outcomes, cardiovascular disease (CVD) onset, and primary biliary cirrhosis (PBC) time-to-transplant. We find that our proposed modeling approach is competitive with other well-known statistical and machine learning approaches for dynamic risk prediction, while offering potential advantages in terms of interepretability of predictions at the individual level.

Abstract
INTRODUCTION Domestic and family violence is a public health problem of epidemic proportions and a significant issue facing the Australian community. It knows no boundaries, is indiscriminate to geographical location, social class, age, religious or cultural background. AIM This study aimed to analyse the processes currently used to identify and respond to domestic and family violence in a large tertiary hospital in Australia, and to classify the benefits and weaknesses of these existing systems. METHODS A qualitative method used semistructured, face-to-face and telephone interviews with key informants in 16 key areas across the hospital. Thematic analysis of the interviews was used to define the key issues and areas of interest identified by participants. RESULTS There was a dearth of existing guidelines or pathways of care for patients experiencing domestic violence. Several strengths and weaknesses were identified in relation to the protocols and systems used by the hospital, including limited training for staff and a lack of standardisation of processes, workplace instructions and clinical guidelines. With the exception of maternity services, no clinical service area used a guideline or work instruction. Most interviewees highlighted the need for the safety and protection of staff and victims as a priority. DISCUSSION Domestic and family violence is an enormous burden on the health system. However, many staff have little or no guidance on dealing with it or are unaware of existing protocols or guidelines for detection or response. Participants recommended further education and training for staff, consistent guidelines, specialist liaison and more educational and information resources for staff and patients. Further investigation and discussions with patients affected by violence is warranted to provide robust recommendations for policy change.

Changes in mental health and drug use among men who have sex with men using daily and event-driven pre-exposure prophylaxis: Results from a prospective demonstration project in Amsterdam, the Netherlands. EClinicalMedicine 2020; 26:100505. [PMID: 33089120 PMCID: PMC7564518 DOI: 10.1016/j.eclinm.2020.100505] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 07/03/2020] [Accepted: 07/28/2020] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Gay, bisexual and other men who have sex with men (GBMSM) are at increased risk of mental health disorders and drug use. In GBMSM taking pre-exposure prophylaxis (PrEP) for HIV, the proportion engaging in risk behaviors could increase due to decreased perception in HIV risk. In turn, this could leave them further susceptible to mental health disorders. METHODS The AMsterdam PrEP study (AMPrEP) is a demonstration project offering a choice of daily PrEP or event-driven PrEP regimen at the STI clinic of the Public Health Service of Amsterdam. Eligible participants were HIV-negative GBMSM and transgender people at risk of HIV, aged ≥18 years. We assessed anxiety and depressive mood disorders (Mental Health Inventory 5), sexual compulsivity (Sexual Compulsivity Scale), alcohol use disorder (Alcohol Use Disorder Identification Test), and drug use disorder (Drug Use Disorder Identification Test) using yearly self-administered assessments (August 2015-September 2018). The proportion of mental health problems were analyzed and changes over time and between regimen were assessed using a logistic regression model. Variables associated with the development or recovery of disorders were assessed using a multistate Markov model. OUTCOMES Of 376 enrolled, we analyzed 341 participants with data at baseline and at least one follow-up visit. During a median follow-up of 2.5 years (IQR=2.3-2.7), the proportion assessed with sexual compulsivity decreased from 23% at baseline to 10% at the last visit (p<0.001) and drug use disorder decreased from 38% at baseline to 31% at the last visit (p = 0.004). No changes occurred in proportion assessed with anxiety/depressive mood disorders (20% at baseline, 18% at last visit, p = 0.358) or alcohol use disorder (28% at baseline, 22% at the last visit, p = 0.106). During follow-up, participants reported significant less use of alcohol (p<0.001), nitrites (p<0.001) and ecstasy (p<0.001). We found no differences between daily and event-driven PrEP users. The development and recovery of disorders during follow-up were highly interrelated. INTERPRETATION Mental health disorders are prevalent among those initiating PrEP. We did not find increases in mental health disorders during PrEP use, but rather a decrease in sexual compulsivity and drug use disorders. The initial prevalence of mental health disorders in our study point at the continuous need to address mental health disorders within PrEP programs.

Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) among undocumented migrants and uninsured legal residents in Amsterdam, the Netherlands: a cross-sectional study. Antimicrob Resist Infect Control 2020; 9:118.

Abstract
BACKGROUND Nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA) is associated with an increased risk of infection. Colonization with MRSA is observed in < 1% of the general Dutch population. Increased risk for MRSA carriage is known to occur in several key groups, one of which is asylum seekers. However, little is known about MRSA carriage among undocumented migrants and uninsured legal residents. This study aimed to determine the prevalence of nasal MRSA carriage among these groups in Amsterdam, the Netherlands. METHODS In this cross-sectional study, between October 2018 and October 2019, undocumented migrants and uninsured legal residents aged 18 years or older who were able to understand one of the study languages were recruited at an NGO health care facility in Amsterdam, the Netherlands, for general practitioner (GP) consultations. Participants were asked questions on demographics, migration history, antibiotic use and other possible risk factors for MRSA carriage and were screened for nasal MRSA carriage by selective culturing e-swabs. Characteristics of MRSA-negative and MRSA-positive participants were compared using univariable logistic regression analysis with Firth's correction. RESULTS Of the 3822 eligible patients, 760 were screened for nasal MRSA carriage (19.9%). Of the 760 participants, over half were male (58%; 442/760) and originated mainly from Africa (35%; 267/760), Asia (30%; 229/760) and North or South America (30%; 227/760). In total, 705/760 participants (93%) were undocumented migrants and 55/760 (7%) were uninsured legal residents of Amsterdam. The overall prevalence of nasal MRSA carriage was 2.0% (15/760) (95%CI 1.1 to 3.2%), with no difference between undocumented migrants (14/705) (2.0, 95%CI 1.1 to 3.3%) and uninsured legal residents (1/55) (1.8, 95%CI 0.1 to 9.7%). Genotyping showed no clustering of the 15 isolates. MRSA carriage was not associated with sociodemographic, migration history or other possible risk factors. Nevertheless, this study had limited power to detect significant determinants. Three participants (3/15; 20%) harbored Panton-Valentine leukocidin (PVL)-positive isolates. CONCLUSION Even though our study population of undocumented migrants and uninsured legal residents had a higher prevalence of nasal MRSA carriage compared to the general Dutch population, the prevalence was relatively low compared to acknowledged other high-risk groups.

Abstract
Abstract
Background
AL-amyloidosis has a rapid clinical progression, with cardiac involvement associated with a particularly poor prognosis. Cardiac amyloidosis is diagnosed by either invasive biopsy or conventional echocardiographic parameters such as increased wall thickness, in the absence of other causes. More recently, novel parameters including 2D longitudinal strain have demonstrated diagnostic utility in a range of infiltrative cardiomyopathies including cardiac amyloidosis.
Aim/Method: We sought to evaluate traditional and novel echocardiographic parameters in their ability to predict adverse outcomes in a cohort of AL-amyloid patients. 80 patients who had transthoracic echocardiograms at a single centre were included. Comprehensive echocardiographic assessment was performed, including left ventricular ejection fraction (LVEF), LV Global Longitudinal Strain (GLS), LV mass (indexed to BSA). The primary endpoint was a composite of of major adverse cardiac events (MACE) and all-cause mortality, that was assessed by interrogation of the medical records on a specified censor date.
Results
At a mean follow-up (time from echo to censor date) of 5.4 ± 2.6years, 38/80 (47.5%) of patients experienced the primary endpoint of MACE or death, of which 25/80 (31%) were deaths. LVEF (59 ± 5.6%vs56 ± 6.4%, p = 0.04), GLS (17.4 ± 3.9%vs14.8 ± 4.9%, p = 0.01) basal longitudinal strain (12.3 ± 3.2%vs9.6 ± 3.9%, p = 0.002), indexed LV mass (107 ± 36g/m2vs130 ± 34g/m2, p = 0.06) and E/E’ (13.7 ± 4.9vs20.6 ± 9.6, p < 0.001) were all significantly different between patients who experienced the primary endpoint and those that didn’t. The strongest predictors of outcome were E/E’ (AUC 0.74), LV mass (AUC 0.73) and the ratio GLS:LV mass (AUC 0.73). An E/E’ of 15 had a sensitivity of 71% and specificity of 69%, while an indexed LV mass of 108 had a sensitivity and specificity of 74% and 67% respectively. GLS to LV mass as a cutoff of 0.16 had a sensitivity and specificity of 70% and 69% respectively.
Conclusion
In a cohort of 80 patients with AL-amyloid cardiomyopathy, almost half (47.5%) reached the primary composite endpoint. Diastolic dysfunction as expressed as E/E’, and LV mass were the most powerful predictors of outcome, while global longitudinal strain and LV basal strain were also reduced, and showed superiority over LV ejection fraction in predicting prognosis.

Abstract
Abstract
Background
An infiltrative cardiomyopathy is a common manifestation of AL-amyloidosis, with cardiac involvement associated with a poor prognosis. Wild-type transthyretin amyloidosis (wt-TTR), is a distinct clinical entity occurring predominantly in men > 65 yrs, that has gained interest recently due to novel treatment options. Regional strain analysis has been shown to discriminate both forms of cardiac amyloidosis from other causes of concentric left ventricular hypertrophy, with a characteristic pattern of ‘apical sparing’. Due to the significant difference in both the course of the disease and treatment options between groups, a non-invasive echocardiographic method of determining subtype would be valuable.
Aim/Method: We sought to compare traditional and novel echocardiographic parameters in a cohort of AL ( n = 80) and wild type (wt-TTR) amyloid ( n = 32) patients. All amyloid patients underwent comprehensive transthoracic echocardiography, including both conventional parameters and LV longitudinal strain. Further novel parameters were computed including the ratio of global longitudinal strain (GLS) to LV ejection fraction (LVEF), as well as GLS to indexed LV mass.
Results
wt-TTR patients had significantly greater LV mass (176 ± 59g/m2vs118 ± 37g/m2, p < 0.001), and worse diastolic dysfunction as expressed as E/E’ (21.5 ± 11vs17 ± 8, p = 0.04). LVEF was significantly lower in wt-TTR patients however remained in the normal range in both groups (53 ± 6%vs57 ± 6%, p = 0.001), whilst GLS was significantly reduced compared to AL-amyloid patients (11.5 ± 3.4%vs16.2 ± 4.6%, p < 0.001). LVEF:GLS was significantly higher in wt-TTR patients (4.93 ± 1.4vs3.87 ± 1.3, p = 0.001) reflecting a more profound reduction in strain with a relatively preserved ejection fraction. Similarly, the ratio of GLS to LV mass was significantly lower in wt-TTR amyloidosis (0.078 ± 0.05vs0.155 ± 0.07, p < 0.001), reflecting a more significant reduction in strain for a given wall thickness in wt-TTR patients. GLS:LV mass was the strongest discriminator between subtypes (AUC 0.82), with a cutoff of 0.09 giving a sensitivity and specificity of 71% and 80% respectively, for detecting wt-TTR.
Conclusion
In this cohort, patients with wt-TTR had significantly greater increase in LV wall thickness and diastolic dysfunction, which may in part reflect their increased age (77vs62). However, GLS was also significantly reduced compared to AL-amyloid, even when accounting for LV ejection fraction and LV mass, suggesting these composite parameters may have value in determining the subtype of cardiac amyloidosis.

Sex, drugs, and sexually transmitted infections: A latent class analysis among men who have sex with men in Amsterdam and surrounding urban regions, the Netherlands. Drug Alcohol Depend 2020; 206:107526.

Abstract
BACKGROUND Men who have sex with men (MSM) are at high risk for sexually transmitted infections (STI) and often have sex while under the influence of drugs (sexualized drug use). We aimed to identify classes of MSM in Amsterdam and in surrounding urban regions with distinctive patterns of sexualized drug use and their association with STI. METHODS In this cross-sectional study, data on MSM were collected at STI clinics in the Netherlands between September-December 2017. Information on drug use, sociodemographics and sexual risk behavior, including lab-confirmed STI (chlamydia, gonorrhea, syphilis and HIV) was collected and compared between Amsterdam and surrounding urban regions. Latent class analysis was used to identify classes with similar drug use patterns, which were then linked to sexual behavior and STI. RESULTS We included 4461 MSM who were a median 35 years old (IQR = 27-47) and mostly Dutch (56.9 %). Use of all drugs was more often reported in Amsterdam compared to surrounding regions (p<0.001). We identified four different classes based on sexualized drug use among Amsterdam participants and three classes in surrounding regions. In both regions, polydrug use classes (compared to classes of no drug use; alcohol use; or few, various drugs) were defined by higher numbers of sexual partners (median range 8-15 vs 4-6, respectively) and higher STI prevalence (range 30.5%-31.8% vs 18.6%-22.8%, respectively). CONCLUSION Given the high prevalence of risk behavior and STIs, MSM in urban settings partaking in sexualized polydrug use might benefit from tailored outreach, screening, and safe sex and drug use interventions.

Abstract
BACKGROUND AND PURPOSE Ischaemic stroke frequently has a cardioembolic (CE) source. Clinical and echocardiographic parameters associated with CE stroke were evaluated. METHODS In all, 93 consecutive ischaemic stroke patients who underwent a transthoracic echocardiogram were retrospectively analysed; strokes were classified by TOAST (Trial of Org 10172 in Acute Stroke Treatment) criteria. Echocardiographic parameters related to CE stroke, including left atrial volumes and function, were compared to 73 healthy controls. RESULTS Of 93 patients (mean age 66.1 years, 56% male), nine (10%) had large artery atherosclerosis, 38 (41%) CE stroke, two (2%) small vessel disease, two (2%) other and 42 (45%) undetermined aetiology. Left atrial (LA) maximum volumes (LAVImax ) and minimum volumes (LAVImin ) were larger in the CE group than the non-CE group (45 vs. 32 ml/m2 , 32 vs. 13 ml/m2 , respectively, P < 0.001), whilst LA function indices including LA emptying fraction and LA function index (LAFI) were lower in the CE group (34% vs. 55%, and 0.12 vs. 0.35, respectively, P < 0.001). Adjusting for clinical characteristics, LAFI ≤0.3 was an independent predictor of CE stroke (adjusted odds ratio 5.3, P = 0.001). Additionally, LAVImax and LAVImin were larger (61 vs. 44 and 32 vs. 24 ml/m2 respectively, P < 0.01) and LAFI significantly lower (0.34 vs. 0.52, P < 0.001) in the undetermined aetiology group versus healthy controls. CONCLUSIONS Left atrial enlargement with reduced LA function was associated with CE stroke and LAFI was the best independent predictor. LA parameters were also altered in the undetermined aetiology group, suggesting an underlying LA myopathy in this subset.

Precore G1896A mutation is associated with reduced rates of HBsAg seroclearance in treated HIV hepatitis B virus co-infected patients from Western Africa. J Viral Hepat 2018; 25:1121-1131.

Abstract
The nucleotide substitution G1896A on the precore (pc) region has been implicated in virological and serological responses during treatment in hepatitis B virus (HBV)-infected patients. Whether this mutation affects the therapeutic course of HIV-HBV co-infected patients, especially from Western Africa, is unknown. In this prospective cohort study, 86 antiretroviral (ARV)-naïve HIV-HBV co-infected patients from Côte d'Ivoire, initiating ARV-treatment containing lamivudine (n = 53) or tenofovir (n = 33), had available baseline pc sequences. Association of the pcG1896A mutation with time to undetectable HBV-DNA, hepatitis B "e" antigen (HBeAg) seroclearance (in HBeAg-positive patients), and hepatitis B surface antigen (HBsAg) seroclearance was evaluated using Cox proportional hazards regression. At ARV-initiation, median HBV-DNA was 6.04 log10 copies/mL (IQR = 3.70-7.93) with 97.7% harbouring HBV genotype E. Baseline pcG1896A mutation was identified in 51 (59.3%) patients, who were more commonly HBeAg-negative (P < .001) and had basal core promotor A1762T/G1764A mutations (P < .001). Patients were followed for a median 36 months (IQR = 24-36). Cumulative proportion of undetectable HBV-DNA was significantly higher in patients with baseline mutation (pcG1896A = 86.6% vs no pcG1896A = 66.9%, P = .04), but not after adjusting for baseline HBV-DNA levels and anti-HBV agent (P = .2). No difference in cumulative proportion of HBeAg seroclearance was observed between mutation groups (pcG1896A = 57.1% vs no pcG1896A = 54.3%, P = .7). Significantly higher cumulative proportion of HBsAg seroclearance was observed in patients without this mutation (pcG1896A = 0% vs no pcG1896A = 36.9%, P < .001), even after adjusting for baseline HBsAg quantification and anti-HBV agent (P < .001). In conclusion, lacking the pcG1896A mutation before ARV initiation appeared to increase HBsAg seroclearance rates during treatment. The therapeutic implications of this mutation need further exploration in this setting.

HIV-positive men who have sex with men are at high risk of development of significant liver fibrosis after an episode of acute hepatitis C. J Viral Hepat 2017; 24:832-839.

Abstract
Acute hepatitis C virus infection remains a major health concern in human immunodeficiency virus(HIV)-infected men who have sex with men (MSM). New direct-acting antiviral agent (DAA) combination therapy has not yet been approved for the treatment for acute hepatitis C virus(HCV), thereby potentially causing deferral of HCV treatment. Therefore, we aimed to study the course of liver disease after an episode of acute HCV. This study is a retrospective single-centre cohort of HIV-positive MSM with acute HCV infection. Liver fibrosis was estimated by Fibroscan® and Fibrotest® . Liver-related and non-liver-related outcomes were documented. Overall 213 episodes of acute HCV infection in 178 men were documented. Median follow-up for all included patients was 38.7 months. Spontaneous HCV clearance was found in 10.8% of patients, which was significantly associated with older age, lower HCV RNA levels, and higher ALT levels upon initial acute HCV diagnosis. Treatment with interferon-based therapy was initiated in 86.3% of cases, resulting in a sustained virological response(SVR) rate of 70.7%. After 3 years' follow-up, significant liver fibrosis of METAVIR F2 stage or higher was found in 39.4% of patients after first acute HCV diagnosis. Higher age, physician-declared alcoholism, and nonresponse to acute HCV therapy were independently associated with higher fibrosis stages. Ten patients died during the observation period (IR 1.4/100 patient-years) and four during interferon treatment. Significant liver fibrosis is a common finding in HIV-positive MSM following acute HCV infection despite high treatment uptake and cure rates, suggesting the need for close liver disease monitoring particularly if HCV treatment is deferred.

Clinical and microbiological determinants of severe and fatal outcomes in patients infected with Enterobacteriaceae producing extended-spectrum β-lactamase. Eur J Clin Microbiol Infect Dis 2017; 36:1261-1268.

Abstract
Although extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae have become a worldwide public health concern, little is known regarding the clinical course of colonized or infected individuals. Our objective was to characterize the determinants of fatal outcomes related to ESBL-producing microorganisms at a large hospital in Paris, France. In 2012-2013, all consecutive patients with clinical samples testing positive for ESBL-producing Enterobacteriaceae at Saint-Antoine Hospital were identified. Patient clinical data were obtained at hospital entry, while information on intensive care unit (ICU) admissions and death were prospectively collected. Risk-factors for fatal 1-year outcomes were assessed using logistic regression. In total, 643/4684 (13%) ESBL-positive samples were observed, corresponding to 516 episodes (n = 206, 40% treated) among 330 patients. Most episodes were nosocomial-related (n = 347/516, 67%) involving Escherichia coli (n = 232/516, 45%) or Klebsiella pneumoniae (n = 164/516, 32%). Empirical antibiotic therapy was adequate in 89/206 (43%) infections, while the median length of hospital stay was 30 days [interquartile range (IQR) = 11-55] and 39/201 (19%) were admitted to the ICU. Overall, 104/241 patients (43%) with available data died within 1 year. In the multivariable analysis, 1-year death was associated with age >80 years (p = 0.01), concomitant comorbidity (p = 0.001), nosocomial-acquired infection (p = 0.002), and being infected rather than colonized (p < 0.001). In this series of patients with identified samples of ESBL-producing Enterobacteriaceae, hospital burden was large and 1-year mortality rates high. Understanding which patients in this setting would benefit from broad-spectrum empirical antibiotic therapy should be further examined.

Abstract
Formation of intra-abdominal adhesions is a common consequence of abdomino-pelvic surgery, radiation therapy, and inflammatory processes. In a small but clinically significant proportion of patients, adhesive disease may develop, wherein adhesions lead to a variety of chronic symptoms such as abdominal distension, pain, nausea, and abnormal bowel movement pattern which can be daily, intermittent, or episodic. Due to the chronic and troublesome nature of these symptoms, adhesive disease may be life-altering in many patients, particularly when not recognized and appropriately addressed, as is the case not infrequently. In addition, there is a paucity of literature regarding the evaluation and management of patients with suspected abdominal adhesive disease. Therefore, in this concise review, we provide a clinically practical synopsis of the etiopathogenesis, symptoms, differential diagnosis, evaluation, and treatment of abdominal adhesive disease.

Abstract
In hepatitis B "e" antigen (HBeAg) positive patients with hepatitis B virus (HBV) mono-infection, intensification of nucleos(t)ide analogue treatment with pegylated interferon (PegIFN) could help induce higher HBeAg seroclearance rates. Our aim was to determine the long-term effect of adding PegIFN to tenofovir (TDF)-containing antiretroviral therapy on seroclearance in HBeAg-positive patients co-infected with the human immunodeficiency virus (HIV) and HBV. In this prospective matched cohort study, 46 patients with 1-year PegIFN intensification during TDF-containing antiretroviral therapy (TDF+PegIFN) were matched 1:1 to controls undergoing TDF without PegIFN (TDF) using a time-dependent propensity score based on age, CD4+ count and liver cirrhosis status. Kinetics of HBeAg quantification (qHBeAg) and hepatitis B surface antigen quantification (qHBsAg) were estimated using mixed-effect linear regression and time to HBeAg seroclearance or HBsAg seroclearance was modelled using proportional hazards regression. At baseline, previous TDF exposure was a median 39.8 months (IQR=21.4-59.4) and median qHBeAg and qHBsAg levels were 6.9 PEIU/mL and 3.72 log10 IU/mL, respectively (P>.5 between groups). Median follow-up was 33.4 months (IQR=19.0-36.3). During intensification, faster average declines of qHBeAg (-0.066 vs -0.027 PEIU/mL/month, P=.001) and qHBsAg (-0.049 vs -0.026 log10 IU/mL/month, P=.09) were observed in patients undergoing TDF+PegIFN vs TDF, respectively. After intensification, qHBeAg and qHBsAg decline was no different between groups (P=.7 and P=.9, respectively). Overall, no differences were observed in HBeAg seroclearance (TDF+PegIFN=13.2 vs TDF=12.6/100 person·years, P=.5) or HBsAg seroclearance rates (TDF+PegIFN=1.8 vs TDF=1.3/100 person·years, P=.7). In conclusion, PegIFN intensification in HBeAg-positive co-infected patients did not lead to increased rates of HBeAg or HBsAg clearance, despite faster declines of antigen levels while on PegIFN.

Gender differences in psychotropic use across Europe: Results from a large cross-sectional, population-based study. Eur Psychiatry 2015; 30:778-88.

Abstract
BACKGROUND In many epidemiological studies, women have been observed to consume psychotropic medication more often than men. However, the consistency of this relationship across Europe, with differences in mental health care (MHC) resources and reimbursement policies, is unknown. METHODS Questions on 12-month psychotropic use (antidepressants, benzodiazepines, antipsychotics, mood stabilizers) were asked to 34,204 respondents from 10 European countries of the EU-World Mental Health surveys. Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) criteria were used to determine 12-month prevalence of mood/anxiety disorders using the Composite International Diagnostic Interview (v3.0). RESULTS For all participating countries, women were significantly more likely than men to use psychotropic medication within the previous 12 months (overall-OR=2.04, 95% CI: 1.81-2.31). This relationship remained significant after adjusting for common sociodemographic factors (age, income level, employment status, education, marital status) and country-level indicators (MHC provision, private household out-of-pocket expenditure, and Gender Gap Index). In multivariable gender-stratified risk-factor analysis, both women and men were more likely to have taken psychotropic medication with increasing age, decreasing income level, and mental health care use within the past 12 months, with no significant differences between genders. When only including participants with a mental disorder, gender differences overall were still significant with any 12-month mood disorder but not with any 12-month anxiety disorder, remaining so after adjusting for sociodemographic characteristics and country-level indicators. CONCLUSIONS Women use psychotropic medication consistently more often than men, yet reasons for their use are similar between genders. These differences also appear to be contingent on the specific mental disorder.

Abstract
BACKGROUND Postnatal depression is associated with poorer parenting quality, but there are few studies examining maternal-specific cognitive processes that may impact on parenting quality. In this study, we examined the impact of rumination on parental problem-solving effectiveness in dysphoric and non-dysphoric postnatal mothers. METHODS Fifty-nine mothers with a infant aged 12 months and under, 20 of whom had a Beck Depression Score II (BDI-II) score ≥ 14, and 39 who scored less than 14 on the BDI-II were randomly assigned to either a rumination or distraction condition. Problem-solving effectiveness was assessed post-induction with the "Postnatal Parental Problem-Solving Task" (PPST), which was adapted from the Means Ends Problem-solving task. Parental problem-solving confidence was also assessed. RESULTS Dysphoric ruminating mothers exhibited poorer problem-solving effectiveness and poorer confidence regarding their problem-solving compared to dysphoric distracting, non-dysphoric distracting, and non-dysphoric ruminating mothers. LIMITATIONS A self-report measure of depressed mood was used. CONCLUSIONS Rumination may be a key mechanism associated with both depressive mood and maternal parenting quality during the postnatal period.

Abstract
Filarial infection in humans is initiated when a mosquito deposits third-stage parasite larvae (L3) in the skin. Langerhans cells (LCs) and dermal dendritic cells (DDCs) are the first cells that the parasite encounters, and L3s must evade these highly effective antigen-presenting cells to establish infection. To assess LC and DDC responses to L3 in human skin, we employed three models of increasing physiologic relevance: in vitro-generated LCs, epidermal blister explants and full-thickness human skin sections. In vitro-generated LCs expressed TLR1-10 and robustly produced IL-6 and TNF-α in response to PolyI:C, but pre-exposure to L3s did not alter inflammatory cytokine production or TLR expression. L3s did not modulate expression of LC markers CDH1, CD207, or CD1a, or the regulatory products TSLP or IDO in epidermal explants or in vitro-generated LC. LC, CD14+ DDC, CD1c+ DC and CD141+ DC from human skin sections were analysed by flow cytometry. While PolyI:C potently induced CCL22 production in LC, CD1c+ DC, and CD141+ DC, and IL-10 production in LC, L3s did not modulate the numbers of or cytokine production by any skin DC subset. L3s broadly failed to activate or modulate LCs or DDCs, suggesting filarial larvae expertly evade APC detection in human skin.
