Mental health and chemical dependency services at US transplant centers.

The purpose of this study was to assess the availability of mental health (MH) and chemical dependency (CD) services at US transplant centers, because appropriate psychosocial assessment and care is associated with better transplant outcomes. We used the 2017-2018 American Hospital Association survey, Area Health Resource File, and Centers for Medicare & Medicaid Services Hospital Compare databases to quantify availability of services and examined associations of hospital- and health services area-level characteristics with odds of offering services with generalized linear mixed models. We found that 15% of transplant centers did not offer MH services and 62% did not offer CD services. Hospitals were more likely to offer MH services if they were larger (OR [95% CI]: 1.03 [1.01, 1.06]) and had a lower rate of uninsured patients in the health services area (OR [95% CI]: 0.89 [0.80, 0.99]) and were more likely to offer CD services if they were larger (OR [95% CI]: 1.02 [1.01, 1.03]) or were members of a system (OR [95% CI]: 2.31 [1.26, 4.24]). Additional research is needed to understand whether lack of MH or CD services at transplant centers affects patients' ability to access comprehensive psychosocial care and whether this affects patient outcomes.

Liver Transplant Recipients Older Than 60 Years Show Executive and Memory Function Improvement Comparable to Younger Recipients.

BACKGROUND: Increasing numbers of patients over the age of 60 are undergoing liver transplantation. OBJECTIVE: We sought to determine whether age or clinical morbidities were associated with pre- and post-transplant executive and memory performance using the Brief Test of Adult Cognition by Telephone (BTACT). METHODS: Participants included 36 recipients with n = 20 in the older group (>60 y) and n = 16 in the younger group (≤60 years). The BTACT was administered an average of 3 months before transplant, and at follow-up post-transplant intervals of 3, 6, and 9 months. BTACT composite scores for memory and executive function with age and education norms were obtained. RESULTS: Older recipients were more likely to have hepatocellular carcinoma, a lower biological MELD score at transplant, less cellular rejection, and fewer post-operative hospital days. Older and younger recipients showed comparable pre-transplant executive and memory function and comparable post-transplant improvement. Both older and younger patients showed statistically significant improvement in executive function scores at 3 months post-transplant and maintained improvement at 6 and 9 months. Memory function improved significantly in older patients by 6 months post-transplant but did not improve significantly in the younger group. CONCLUSION: Older liver transplant recipients were more likely to have hepatocellular carcinoma and a lower biological MELD score than younger recipients, but both age groups showed comparable pre-transplant cognitive performance and post-transplant cognitive improvement. Additionally, a normed telephone test can be used to effectively screen and track executive and memory function post-transplant.

Psychosocial Risk Predicts New Episode Depression After Heart Transplant.

BACKGROUND: Psychosocial assessment is an essential component of the pretransplant evaluation. Many individuals have significant psychosocial problems, and they are either denied for transplantation or deferred from listing and transplant until the psychosocial issues are addressed. OBJECTIVE: The primary aim of this study was to evaluate the outcomes of patients who initially had significant psychosocial problems, but who addressed them and received a heart transplant. METHODS: This retrospective study included heart transplant recipients from 1/1/2000 to 12/31/2012. Those with initial Psychosocial Assessment of Candidates for Transplantation (PACT) scale score <2 were compared with those whose initial score was ≥2 for the variables new onset depression and anxiety, length of stay, rejection, and survival using logistic and linear regression and Cox proportional hazards modeling. RESULTS: Of 164 heart recipients with pretransplant PACT scores, 46 (28%) were female, 154 (94%) were white, and the mean age was 52.7 years. Only 11 (7%) received an initial PACT score <2; these candidates underwent heart transplantation after their scores increased to ≥2. Initial PACT <2 increased the odds of new depression by 11-fold (p = 0.002), but was not associated with differences in survival, posttransplant length of stay, the occurrence of treated episodes of rejection or new anxiety (p ≥ 0.20 for all). CONCLUSION: Among heart recipients, initially high pretransplant psychosocial risk, as assessed by PACT, was associated with posttransplant new episode depression. However, after addressing the primary psychosocial issues before transplant, posttransplant length of stay, organ rejection, and survival were the same as those without prior psychosocial concerns.

Psychosocial Risk Impacts Mortality in Women After Liver Transplantation.

BACKGROUND: Liver transplant candidates undergo psychosocial assessment as a component of their pretransplant evaluation. Global psychosocial assessment scales, including the Psychosocial Assessment of Candidates for Transplantation (PACT), capture and quantify these psychiatric and social variables. OBJECTIVE: Our primary aim was to assess for an association between global PACT score and survival in liver transplant recipients. METHODS: This retrospective cohort study examined records of all liver recipients at one U.S. Transplant Center from 2000 to 2012 with outcomes monitoring until 07/01/2016. We investigated for associations between the following variables and mortality: PACT score, age, gender, marital status, race, alcoholic liver disease (ALD), and body mass index (BMI). Statistical methods included Student's t-test, Wilcoxon rank sum test, chi-square, Fisher's exact test, Kaplan-Meier curve, and Cox proportional hazard models. RESULTS: Of 1040 liver recipients, 538 had a documented PACT score. Among these, PACT score was not associated with mortality. In women, a lower PACT score was associated with mortality (p = 0.003) even after adjustments for age, marital status, and BMI. Women with ALD had a 2-fold increased hazard of death (p = 0.012). Increasing age was associated with increased risk of death for the cohort as a whole (p = 0.019) and for men (p = 0.014). In men, being married and BMI were marginally protective (p = 0.10 and p = 0.13, respectively). CONCLUSIONS: Transplant psychosocial screening scales, specifically the PACT, identify psychosocial burden and may predict post-transplant outcomes in certain populations. In female liver recipients, lower PACT scores and ALD were associated with a greater risk of post-transplant mortality.

Alcohol Craving Predicts Relapse After Residential Addiction Treatment.

AIMS: Replicate the previously reported association of elevated alcohol craving, measured by Penn Alcohol Craving Scale (PACS) during residential treatment, with post-treatment relapse and explore whether elevated craving scores 3 months post-treatment are also associated with subsequent relapse. METHODS: Alcohol craving was assessed with the PACS on admission and at several time points post-treatment in 190 subjects with DSM-IV diagnosis of alcohol dependence admitted to residential treatment. Data about relapse to any drinking (primary outcome measure) was collected at 3, 6, 9 and 12 months after treatment. Cox regression models were used to determine whether PACS scores were associated with relapse. Statistical models were adjusted for meaningful demographic and clinical covariates. RESULTS: Follow-up data was available for 149/190 (78%) of subjects. Elevated PACS scores at discharge were associated with increased relapse risk within the first 3 and 12 months after discharge (P = 0.032 and P = 0.045, respectively). Elevated PACS scores at 3 months were associated with increased risk of subsequent relapse within 12 months after treatment in contacted subjects (P = 0.034) and in the intent-to-treat analysis (P = 0.0001). CONCLUSIONS: Our findings indicate strong association of post-treatment relapse with elevated alcohol craving measured at treatment completion and at 3 months after treatment and justify the use of this measure to guide relapse-prevention efforts.

The 2018 ISHLT/APM/AST/ICCAC/STSW Recommendations for the Psychosocial Evaluation of Adult Cardiothoracic Transplant Candidates and Candidates for Long-term Mechanical Circulatory Support.

The psychosocial evaluation is well-recognized as an important component of the multifaceted assessment process to determine candidacy for heart transplantation, lung transplantation, and long-term mechanical circulatory support (MCS). However, there is no consensus-based set of recommendations for either the full range of psychosocial domains to be assessed during the evaluation, or the set of processes and procedures to be used to conduct the evaluation, report its findings, and monitor patients' receipt of and response to interventions for any problems identified. This document provides recommendations on both evaluation content and process. It represents a collaborative effort of the International Society for Heart and Lung Transplantation (ISHLT) and the Academy of Psychosomatic Medicine, American Society of Transplantation, International Consortium of Circulatory Assist Clinicians, and Society for Transplant Social Workers. The Nursing, Health Science and Allied Health Council of the ISHLT organized a Writing Committee composed of international experts representing the ISHLT and the collaborating societies. This Committee synthesized expert opinion and conducted a comprehensive literature review to support the psychosocial evaluation content and process recommendations that were developed. The recommendations are intended to dovetail with current ISHLT guidelines and consensus statements for the selection of candidates for cardiothoracic transplantation and MCS implantation. Moreover, the recommendations are designed to promote consistency across programs in the performance of the psychosocial evaluation by proposing a core set of content domains and processes that can be expanded as needed to meet programs' unique needs and goals.

PNPLA3 Association with Alcoholic Liver Disease in a Cohort of Heavy Drinkers.

AIMS: Prior studies have established variation at the PNPLA3 gene to be associated with a risk of developing alcoholic liver disease (ALD). We attempt to replicate this finding and other potential genetic variations previously associated with ALD utilizing a case-control design in a cohort of subjects with alcohol use disorders. SHORT SUMMARY: This case-control study performed in a US clinical sample of heavy drinkers, replicates the previously reported association between ALD and rs738409 polymorphism in the PNPLA3 gene in heavy drinkers. This association persisted after accounting for the subject's diabetes status. METHODS: Patients of European ancestry with a history of ALD were identified (n = 169). Controls consisted of patients without ALD who were from the same cohorts and were ≥ 30 years of age, had lifetime total years drinking ≥20 and lifetime maximum drinks per day ≥12 (n = 259). Patients were genotyped for 40 candidate single nucleotide polymorphisms (SNPs) selected for the purpose of testing their association with ALD. The association of each SNP with ALD was tested using a logistic regression model, assuming log-additive allele effects. Bonferroni correction was applied and multivariable logistic regression models were used to account for relevant covariates. RESULTS: Age, sex, and body mass index (BMI) distributions were similar between cases and controls. Diabetes was more prevalent in the ALD cases. Three SNPs were associated with ALD at the nominal significance level (rs738409 in PNPLA3, P = 0.00029; rs3741559 in AQP2, P = 0.0185; rs4290029 in NVL, P = 0.0192); only PNPLA3 rs738409 SNP was significant at the Bonferroni-corrected P-value threshold of 0.00125. Association results remained significant after adjustment for diabetes status. CONCLUSION: Our case-control study confirmed that PNPLA3 rs738409 SNP is associated with ALD. This is an important replication in a US clinical sample with control subjects who had long histories of alcohol consumption.

Elderly recipients of liver transplantation: impact of age and psychosocial variables on outcome.

PURPOSE OF REVIEW: With expanding experience and success of liver transplantation, increasing numbers of elderly candidates await and undergo liver transplantation. There is accumulating evidence that graft survival and mortality does not appear to differ significantly between the young and carefully selected elderly liver transplantation recipients. Although existing evidence suggests that psychosocial factors impact outcomes after liver transplantation in general, no such information is available specifically for elderly (age ≥65 years) liver transplantation recipients. We conducted a broad medical literature review of outcome studies of elderly liver transplantation recipients. In this review article, we summarize the findings and comment on psychosocial variables included in these studies. RECENT FINDINGS: Ten outcome studies have reported on the impact of age on the liver transplantation outcomes. There is increasing evidence of favorable outcomes in elderly liver transplantation recipients. Few of these studies include measures of quality of life, functional improvement and other psychosocial variables. SUMMARY: Very limited information is available about the impact of psychosocial factors on outcomes in elderly liver transplantation recipients. This dearth of information represents a critical gap in our knowledge and has implications for optimal candidate selection and outcomes after liver transplantation.

Alcoholic hepatitis: appropriate indication for liver transplantation?

PURPOSE OF REVIEW: The majority of liver transplantation centers have required patients with alcohol-induced liver disease to demonstrate a period of abstinence (generally 6 months' duration) to qualify for transplant listing. This requirement has excluded patients with alcoholic hepatitis from transplant consideration. Since 2011, several studies have examined the outcomes of patients undergoing liver transplantation with brief abstinence as a lifesaving intervention for alcoholic hepatitis. This review includes each of the recent studies and discusses their implications for general transplant practice. RECENT FINDINGS: A Medical Literature Analysis and Retrieval System search revealed five published studies - three prospective and two retrospective - pertaining to liver transplantation for alcoholic hepatitis. Among patients with medication-nonresponsive alcoholic hepatitis, those who underwent transplantation had superior survival. Liver recipients with alcoholic hepatitis had comparable survival to those with 6 or more months of abstinence. Their relapse rates were not statistically different in the short term over those transplanted with longer abstinence, although some patients in each prospective cohort relapsed to drinking despite narrow inclusion criteria and extensive pretransplant staff reviews and posttransplant surveillance. SUMMARY: Liver transplantation is a reasonable treatment consideration for highly selective cases of alcoholic hepatitis. Further research is needed to refine inclusion criteria, address posttransplant relapse prevention interventions, and monitor long-term outcomes.

The Psychosocial Assessment of Candidates for Transplantation: A Cohort Study of its Association With Survival Among Lung Transplant Recipients.

BACKGROUND: The United Network for Organ Sharing mandates a psychosocial assessment of transplant candidates before listing. A quantified measure for determining transplant candidacy is the Psychosocial Assessment of Candidates for Transplant (PACT) scale. This instrument's predictive value for survival has not been rigorously evaluated among lung transplantation recipients. METHODS: We reviewed medical records of all patients who underwent lung transplantation at Mayo Clinic, Rochester from 2000-2012. A transplant psychiatrist had assessed lung transplant candidates for psychosocial risk with the PACT scale. Recipients were divided into high- and low psychosocial risk cohorts using a PACT score cutoff of 2. The main outcome variable was posttransplant survival. Mortality was analyzed using the Kaplan-Meier estimator and Cox proportional hazard models. RESULTS: This study included 110 lung recipients: 57 (51.8%) were females, 101 (91.8%) Whites, mean age: 56.4 years. Further, 7 (6.4%) recipients received an initial PACT score <2 (poor or borderline candidates) and later achieved a higher score, allowing transplant listing; 103 (93.6%) received initial scores ≥2 (acceptable, good or great candidates). An initial PACT score < 2 was modestly associated with higher mortality (adjusted hazard ratio = 2.73, p = 0.04). CONCLUSIONS: Lung transplant recipients who initially received a low score on the PACT scale, reflecting poor or borderline psychosocial candidacy, experienced greater likelihood of mortality. This primary finding suggests that the psychosocial assessment, as measured by the PACT scale, may provide additional mortality risk stratification for lung transplant candidates.

The association between sleep disturbances and alcohol relapse: A 12-month observational cohort study.

BACKGROUND: Sleep disturbances are extremely common in alcohol recovery. Systematic research into the relationship between alcohol relapse and sleep disturbances using validated scales and accounting for potential confounders is lacking. METHODS: Patients admitted to a 1-month residential addiction treatment program were administered the Pittsburg Sleep Quality Index (PSQI) at admission/discharge. In addition, the Alcohol Use Disorders Identification Test (AUDIT), Patient Health Questionnaire-9 (PHQ-9), and Pennsylvania Alcohol Craving Scale (PACS) were administered. Patients were contacted every 3 months over 1 year following discharge. Associations of clinical factors with time until relapse were examined using univariate Cox proportional hazard models. RESULTS: One-hundred and nineteen patients with alcohol use disorders met inclusion criteria (mean age 50.6 ± 13.2 years, 57% male), relapse data were available for 81 patients. Eighty percent of subjects had other psychiatric diagnoses, 66.3% had sleep disturbances at the time of admission, and 57.1% were using hypnotics; 49.1% of patients had sleep disturbances at discharge. Sleep disturbances at admission and discharge were not associated with alcohol relapse at 12 months (OR = 1.00, 95% CI = 0.89-1.13; p = 0.95 and OR = 0.97, 95% CI = 0.86-1.09; p = 0.61). The PSQI sub-scale scores were also not associated with relapse at 12 months. The use of alcohol to help fall asleep (OR = 3.26, 95% CI = 1.33-7.95; p = 0.008), hypnotic use at admission (OR = 4.03, 95% CI = 1.63-9.97; p = 0.002) and age (OR = 1.03, 95% CI = 1.00-1.06; p = 0.035) were associated with relapse over 12 months. CONCLUSION: In patients completing a residential treatment program, sleep disturbances as measured by the PSQI were not associated with alcohol relapse at 12 months. Alcohol use as a hypnotic and hypnotic use at admission were associated with subsequent relapse.

Association of GATA4 sequence variation with alcohol dependence.

To further explore reports of association of alcohol dependence and response to acamprosate treatment with the GATA4 rs13273672 single nucleotide polymorphism (SNP), we genotyped this and 10 other GATA4 SNPs in 816 alcohol-dependent cases and 1248 controls. We tested for association of alcohol dependence with the 11 SNPs individually and performed a global test for association using a principle components analysis. Our analyses demonstrate significant association between GATA4 and alcohol dependence at the gene level (P = 0.009) but no association with rs13273672. Further studies are needed to identify potential causal GATA4 variation(s) and the functional mechanism(s) contributing to this association.

The course of sleep disturbances in early alcohol recovery: an observational cohort study.

INTRODUCTION: Understanding the course and determinants of sleep disturbances in alcoholic patients may help identify patients at high risk of persistent sleep problems, relapse and guide treatment interventions. METHODS: We prospectively administered the Pittsburgh Sleep Quality Index (PSQI) to all patients (N = 196) admitted to a 1-month residential treatment program. Our analysis excluded patients with active drug abuse/dependence. Demographic data, psychiatric diagnoses, Patient Health Questionnaire-9 (PHQ-9), Alcohol Use Disorders Identification Test (AUDIT) and Inventory of Drug Taking Situations (IDTS) scores were obtained. Univariate and logistic regression analyses were performed using sex, age, hazardous alcohol use, PHQ-9 scores, hypnotic use, and use of alcohol as a hypnotic as correlates to admission PSQI scores and improvement in PSQI scores. RESULTS: A total of 119 alcoholic patients met inclusion criteria (mean age 50.6 ± 13.2 years). The rates of sleep disturbances at admission and discharge were 69.3% and 49.1%, respectively. Self report of using alcohol to fall asleep and use of hypnotics were associated with elevated PSQI scores. Total PSQI scores improved over 4 weeks (p < .001). Change in PSQI scores was not effected by gender, use of hypnotics, hazardous alcohol use, use of alcohol as a hypnotic or co-morbid psychiatric diagnosis. Older age predicted improvement in PSQI scores in patients with sleep disturbances (p = .004). CONCLUSION: While a large proportion of alcoholics had sleep disturbances upon admission and at discharge from a residential treatment program, only older age was associated with improvements in sleep disturbances during early alcohol recovery.

Clinical Utility and Impact of Phosphatidylethanol Testing in Liver Transplantation Evaluations.

BACKGROUND: Phosphatidylethanol (PEth) is a serum biomarker that can detect alcohol use within the last 28 days with excellent sensitivity and specificity. Urinary ethyl glucuronide (uEtG) is commonly used in transplant settings to screen for alcohol use; however, it has several limitations relevant to liver transplantation. Transplant centers are beginning to regularly utilize PEth as part of the screening process for high-risk liver transplantation candidates although the clinical utility of uniform pre-transplant PEth testing is unclear. METHODS: This was a retrospective chart review of all patients evaluated for liver transplantation from December 1, 2019, through May 31, 2022, at a large academic tertiary referral center utilizing uniform serum PEth and uEtG screening. Information regarding the patients' transplantation status, age, sex, race, Model for End-Stage Liver Disease score, and PEth levels was obtained. In those with a positive PEth, we examined if the result would have been detected with uEtG, identified a discrepancy from the documented patient report of last use, led to a change in the Psychosocial Assessment of Candidate for Transplantation score, or influenced the transplant selection committee's decision. RESULTS: Our sample included 865 individuals (mean age = 55.20, 61.27% male and 82.54% white) with calculated Model for End-Stage Liver Disease-Sodium scores ranging from 6.43 to 50.65 (mean: 18.09; median: 16.46). Forty-eight patients were found to have a positive PEth (PEth range 20-1833); 75% of the sample had alcohol-associated liver disease. In 23 of 48 (47.91%) cases, the positive PEth identified alcohol use missed by a concomitant uEtG screen. A positive PEth test identified a discrepancy from patients' self-report in 29 (60.42%) cases and influenced the selection committee's decision in 28 cases (58.33%). CONCLUSION: Uniform pretransplant PEth screening of liver transplant candidates at the time of initial evaluation identified alcohol use that would have been missed by uEtG testing, identified discrepancies from the patient's self-report, and influenced clinical decision-making in a significant number of cases. These findings support the use of uniform PEth screening in liver transplantation evaluations.

Association of the PDYN gene with alcohol dependence and the propensity to drink in negative emotional states.

Synthetic κ-opioid receptor (KOR) agonists induce dysphoric and pro-depressive effects and variations in the KOR (OPRK1) and prodynorphin (PDYN) genes have been shown to be associated with alcohol dependence. We genotyped 23 single nucleotide polymorphisms (SNPs) in the PDYN and OPRK1 genes in 816 alcohol-dependent subjects and investigated their association with: (1) negative craving measured by a subscale of the Inventory of Drug Taking Situations; (2) a self-reported history of depression; (3) the intensity of depressive symptoms measured by the Beck Depression Inventory-II. In addition, 13 of the 23 PDYN and OPRK1 SNPs, which were previously genotyped in a set of 1248 controls, were used to evaluate association with alcohol dependence. SNP and haplotype tests of association were performed. Analysis of a haplotype spanning the PDYN gene (rs6045784, rs910080, rs2235751, rs2281285) revealed significant association with alcohol dependence (p = 0.00079) and with negative craving (p = 0.0499). A candidate haplotype containing the PDYN rs2281285-rs1997794 SNPs that was previously associated with alcohol dependence was also associated with negative craving (p = 0.024) and alcohol dependence (p = 0.0008) in this study. A trend for association between depression severity and PDYN variation was detected. No associations of OPRK1 gene variation with alcohol dependence or other studied phenotypes were found. These findings support the hypothesis that sequence variation in the PDYN gene contributes to both alcohol dependence and the induction of negative craving in alcohol-dependent subjects.

A retrospective study of gender differences in depressive symptoms and risk of relapse in patients with alcohol dependence.

BACKGROUND AND OBJECTIVES: The aim of this study was to investigate potential gender differences in situations associated with heavy alcohol drinking. METHODS: Data from 395 alcohol dependent patients participating in the Mayo Clinic Intensive Addiction Program were evaluated. Each participant completed the inventory of drug taking situations (IDTS), Penn alcohol craving scale (PACS), patient health questionnaire (PHQ-9), and/or Beck depression inventory (BDI). Gender differences in IDTS scores representing three domains (negative, positive, and temptation) of situations associated with heavy alcohol use were examined. RESULTS: Women with alcohol dependence report a higher frequency of heavy drinking in unpleasant emotional (IDTS negative scores mean ± SD women vs. men: 52.3 ± 22.1 vs. 43.8 ± 21.8; p = .0006), and as a result of temptation (IDTS temptation scores mean ± SD women vs. men: 40.4 ± 23.0 vs. 35.3 ± 20.8; p = .035). Upon admission, women also scored significantly higher on depressive symptoms as measured by the BDI (23.4 ± 11.4 vs. 18.2 ± 9.8, p < .001). After controlling for depressive symptom severity as a covariate, the IDTS gender differences were no longer significant. CONCLUSION AND SCIENTIFIC SIGNIFICANCE: Our results suggest that unpleasant or temptation based emotional situations are a vulnerability risk factor for heavy drinking particularly in females. This risk appears to be at least partially driven by depressive symptom burden. Future research is needed to further investigate this finding.

No difference in COVID-19 treatment outcomes among current methamphetamine, cannabis and alcohol users.

BACKGROUND: Poor outcomes of COVID-19 have been reported in older males with medical comorbidities including substance use disorder. However, it is unknown whether there is a difference in COVID-19 treatment outcomes between patients who are current cannabis users, excessive alcohol drinkers and those who use a known hazardous stimulant such as methamphetamine (METH). METHODS: Electronic medical records (EMR) of COVID-19 patients with current METH (n = 32), cannabis (n = 46), and heavy alcohol use (n = 44) were reviewed. COVID-19 infection was confirmed by positive SARS-CoV-2 PCR test, current drug use was confirmed by positive urine drug testing, and alcohol use was identified by a blood alcohol concentration greater than 11 mg/dl. Multivariate linear regression models as well as the firth logistic regression models were used to examine the effect of substance use group (METH, cannabis, or alcohol) on treatment outcome measures. RESULTS: A total of 122 patients were included in this analysis. There were no significant differences found between drug groups in regards to key SARS-CoV-2 outcomes of interest including ICU admission, length of stay, interval between SARS-CoV-2 positive test and hospital discharge, delirium, intubation and mortality after adjusting for covariates. About one-fifth (21.9% in METH users, 15.2% in cannabis users, and 20.5% in alcohol users) of all patients required ICU admission. As many as 37.5% of METH users, 23.9% of cannabis users, and 29.5% of alcohol users developed delirium (P = 0.4). There were no significant differences between drug groups in COVID-19 specific medication requirements. Eight patients in total died within 10 months of positive SARS-CoV-2 PCR test. Two patients from the METH group (6.3%), two patients from the cannabis group (4.3%), and four patients from the alcohol group (9.1%) died. DISCUSSION: The study outcomes may have been affected by several limitations. These included the methodology of its retrospective design, relatively small sample size, and the absence of a COVID-19 negative control group. In addition, there was no quantification of substance use and many covariates relied on clinical documentation or patient self-report. Finally, it was difficult to control for all potential confounders particularly given the small sample size. CONCLUSION: Despite these limitations, our results show that current METH, cannabis, and heavy alcohol users in this study have similar treatment outcomes and suffer from high morbidity including in-hospital delirium and high mortality rates within the first-year post COVID-19. The extent to which co-morbid tobacco smoking contributed to the negative outcomes in METH, cannabis, and alcohol users remains to be investigated.

Sex difference in alcohol withdrawal syndrome: a scoping review of clinical studies.

Background: We conducted a review of all studies comparing clinical aspects of alcohol withdrawal syndrome (AWS) between men and women. Methods: Five databases (PubMed, Cochrane, EMBASE, Scopus and Clinical Trials) were searched for clinical studies using the keywords "alcohol withdrawal syndrome" or "delirium tremens" limited to "sex" or "gender" or "sex difference" or "gender difference." The search was conducted on May 19, 2023. Two reviewers selected studies including both male and female patients with AWS, and they compared males and females in type of AWS symptoms, clinical course, complications, and treatment outcome. Results: Thirty-five observational studies were included with a total of 318,730 participants of which 75,346 had AWS. In twenty of the studies, the number of patients presenting with or developing AWS was separated by sex, resulting in a total of 8,159 (12.5%) female patients and a total of 56,928 (87.5%) male patients. Despite inconsistent results, males were more likely than females to develop complicated AWS [delirium tremens (DT) and AW seizures, collective DT in Males vs. females: 1,792 (85.4%) vs. 307 (14.6%), and collective seizures in males vs. females: 294 (78%) vs. 82 (22%)]. The rates of ICU admissions and hospital length of stay did not show sex differences. Although variable across studies, compared to females, males received benzodiazepine treatment at higher frequency and dose. One study reported that the time from first hospitalization for AWS to death was approximately 1.5 years shorter for males and males had higher mortality rate [19.5% (197/1,016)] compared to females [16% (26/163)]. Conclusion: Despite the significant heterogeneity of the studies selected and the lack of a focus on investigating potential sex differences, this review of clinical studies on AWS suggests that men and women exhibit different AWS manifestations. Large-scale studies focusing specifically on investigating sex difference in AWS are needed.

Impact of Recipient Age at Liver Transplant on Long-term Outcomes.

BACKGROUND: The age of a liver transplant (LT) candidate is one of many variables used in the transplant selection process. Most research about the age at transplant has used prespecified age ranges or categories in assessing associations with transplant outcomes. However, there is a lack of knowledge about the age at transplant and survival. This study aimed to examine associations of age at transplant as a continuous variable, in conjunction with other patient and disease-related factors, with patient and graft survival after LT. METHODS: We used the Standard Transplant Analysis and Research data to identify LT recipients between January 2002 and June 2018. Cox regression models with a restricted cubic spline term for age examined associations with graft and patient survival after LT. We assessed the interactions of age with recipients' sex, race/ethnicity, region, indication for transplant, body mass index, model for end-stage liver disease score, diabetes, functional status at transplant, and donor risk index. RESULTS: Age at the time of LT showed a nonlinear association with both graft and patient survival. Each demographic, clinical, transplant-related, and donor-related factor influenced these relationships differently. CONCLUSIONS: Our results suggest that some older LT candidates may be better than some younger candidates and that clinicians should not exclusively use age to determine who receives LT.

Psychiatric disorders during pregnancy in asymptomatic and mildly symptomatic SARS-CoV-2 positive women: Prevalence and effect on outcome.

The effect of psychiatric comorbidity on pregnancy outcome among SARS-CoV-2 positive women with asymptomatic and mildly symptomatic infections remains largely unknown. We reviewed the electronic medical records of all pregnant women who received care at Mayo Health System and tested positive for SARS-CoV-2 (RT-PCR) from March 2020 through October 2021. Among 789 patients, 34.2% (n = 270) had psychiatric comorbidity. Of those with psychiatric comrobidity, 62.2% (n = 168) had depression prior to pregnancy, and 5.2% (n = 14) reported new-onset depression during pregnancy. Before pregnancy, 65.6% (n = 177) had anxiety, and 4.4% (n = 12) developed anxiety during pregnancy Thirteen percent of SARS-CoV-2 positive pregnant women (n = 108) received psychotropic medication during pregnancy. In addition, 6.7% (n = 18) and 10.7% (n = 29) of pregnant women with psychiatric comorbidity had documented nicotine, cannabis and/ or illicit substance use during and prior to pregnancy, respectively. We depicted a significantly higher risk for cesarean delivery [35.6% vs. 24.9%) in asymptomatic and mildly symptomatic SARS-CoV-2 positive pregnant women with psychiatric comorbidity. In conclusion, the prevalence rates of depression, anxiety, and prescribed antidepressant medications during pregnancy among asymptomatic and mildly symptomatic SARS-CoV-2 infected women were substantially higher than average, which negatively impacted pregnancy and neonatal outcomes.
