Abstract
BACKGROUND Alcohol consumption is widespread with over half of the individuals over 18 years of age in the U.S. reporting alcohol use in the last 30 days. Moreover, 9 million Americans engaged in binge or chronic heavy drinking (CHD) in 2019. CHD negatively impacts pathogen clearance and tissue repair, including in the respiratory tract, thereby increasing susceptibility to infection. Although, it has been hypothesized that chronic alcohol consumption negatively impacts COVID-19 outcomes; the interplay between chronic alcohol use and SARS-CoV-2 infection outcomes has yet to be elucidated. METHODS In this study we employed luminex, scRNA sequencing, and flow cytometry to investigate the impact of chronic alcohol consumption on SARS-CoV-2 anti-viral responses in bronchoalveolar lavage cell samples from humans with alcohol use disorder and rhesus macaques that engaged in chronic drinking. FINDINGS Our data show that in both humans (n = 6) and macaques (n = 11), the induction of key antiviral cytokines and growth factors was decreased with chronic ethanol consumption. Moreover, in macaques fewer differentially expressed genes mapped to Gene Ontology terms associated with antiviral immunity following 6 month of ethanol consumption while TLR signaling pathways were upregulated. INTERPRETATION These data are indicative of aberrant inflammation and reduced antiviral responses in the lung with chronic alcohol drinking.

Cross sectional analysis of the effect of alcohol on pulmonary function in a cohort of men and women living with HIV. Alcohol 2022; 101:45-51. [PMID: 35306109 PMCID: PMC9117518 DOI: 10.1016/j.alcohol.2022.03.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 03/01/2022] [Accepted: 03/10/2022] [Indexed: 11/21/2022]
Abstract
People living with HIV (PLWH) are at increased risk for noncommunicable diseases such as lung disease in part due to opportunistic infections including pneumonia. HIV infection is associated with increased prevalence of impaired lung function and abnormal gas exchange. Alcohol use disorder (AUD) is exceedingly common in PLWH and is associated with higher risk of pneumonia in PLWH. Alcohol use may lead to lung damage through several mechanisms. Data on the long-term effect of AUD on pulmonary function in PLWH are sparse and conflicting. To evaluate this relationship, we conducted a cross-sectional analysis of adult PLWH in care in Louisiana. We hypothesized that chronic alcohol use would be associated with subsequent pulmonary dysfunction in a dose-dependent fashion. All participants performed standardized spirometry on study entry. In total, 350 participants with acceptable spirometry were included in this analysis. Thirty-one percent of participants were female. Women reported less lifetime alcohol use and less smoking; however, they reported more chronic respiratory symptoms. In adjusted models, total lifetime alcohol use was not associated with spirometry measures of pulmonary function. HIV-related variables (CD4 count and viral load) were also not associated with measures of pulmonary function. We then conducted sex-stratified analyses to eliminate residual confounding of sex and similarly found no association of total lifetime alcohol use and pulmonary function. We found no association of AUDIT score or early life alcohol use and pulmonary function. In latent class factor analysis, current heavy alcohol use was associated with lower measures of pulmonary function as compared to former heavy alcohol use. In summary, in this cohort of New Orleanian men and women living with HIV with robust measures of alcohol use, though total lifetime alcohol use and early life alcohol use were not associated with pulmonary function, current heavy alcohol use was associated with impaired pulmonary function.

Abstract
AbstractThe learning hospital is distinguished by ceaseless evolution of erudition, enhancement, and implementation of clinical best practices. We describe a model for the learning hospital within the framework of a hospital infection prevention program and argue that a critical assessment of safety practices is possible without significant grant funding. We reviewed 121 peer-reviewed manuscripts published by the VCU Hospital Infection Prevention Program over 16 years. Publications included quasi-experimental studies, observational studies, surveys, interrupted time series analyses, and editorials. We summarized the articles based on their infection prevention focus, and we provide a brief summary of the findings. We also summarized the involvement of nonfaculty learners in these manuscripts as well as the contributions of grant funding. Despite the absence of significant grant funding, infection prevention programs can critically assess safety strategies under the learning hospital framework by leveraging a diverse collaboration of motivated nonfaculty learners. This model is a valuable adjunct to traditional grant-funded efforts in infection prevention science and is part of a successful horizontal infection control program.

Abstract
BACKGROUND Alcohol use disorders (AUDs), including alcohol dependence and alcohol abuse defined according to specific DSM-IV and ICD-10 criteria, can be potentially lethal, because they are associated with several medical and psychiatric conditions. This study aimed to describe the causes of hospitalization of a large cohort of subjects with alcohol dependence (alcoholics) enrolled in Florence (Italy) over a 5-year follow-up period and to evaluate the effect of hospitalization on overall survival. METHODS One thousand one hundred and thirty alcoholics, newly diagnosed from 1997 to 2001, were linked to the Regional Mortality Registry for update of vital status as of December 31, 2006, and to the Hospital Discharge electronic archives of the Regional Health System of Tuscany to verify hospital admissions (HAs) during the 5-year postcohort enrollment follow-up. Kaplan-Meier survival and Cox regression analyses were performed to evaluate any association of HA with overall survival. RESULTS A total of 3,916 new hospitalizations occurred during the 5-year follow-up. Most alcoholics (70.6%) reported at least 1 new hospitalization, with a first hospitalization rate of 61.7 per 100 person-years in the first year of follow-up. The mean number of hospitalizations per admitted subject was 4.87 (SD 7.4), and mean length of hospital stay was 8.5 days (SD 11.3). The main causes of hospitalization were mental disorders and diseases of the digestive system, as well as accidents or violence. Among those alcoholics alive after 1 year of follow-up, a significantly increased risk of dying in the following years could be predicted by early hospitalization in the 12 months preceding (hazard ratio [HR] 1.73; 95% confidence interval [CI] 1.15 to 2.60) or following (HR 3.59; 95% CI 2.31 to 5.61) enrollment in the cohort. CONCLUSIONS Our results confirm the association of AUDs with several serious medical conditions. This fact may be responsible for a high impact on health resource utilization and high social costs. Early hospitalization significantly predicts vital status at 5 years.

Abstract
PURPOSE Pneumonia is common and more severe in human immunodeficiency virus (HIV)-infected patients. Alcohol consumption in pneumonia patients without HIV is associated with excess mortality and morbidity. However, studies are lacking on the impact of alcohol on pneumonia and HIV. Our goal was to determine if alcohol use was an independent risk factor for pneumonia severity in HIV-infected patients. METHODS Secondary analysis of prospective cohort study data evaluating early bronchoscopy for pneumonia diagnosis in HIV patients between 2007 and 2011 was conducted. We defined AUDs using an alcohol use disorder identification test (AUDIT) score as follows: ≥8 indicates hazardous drinking and ≥14 indicates dependence. We quantified pneumonia severity using the pneumonia severity index (PSI). Multivariable linear regression was used to investigate the independent association between alcohol and pneumonia severity. RESULTS A total of 196 HIV+ individuals comprised our cohort. Most cohort subjects were middle-aged African American men. Most subjects (70 %) reported not taking antiretroviral therapy. The overall prevalence of hazardous drinking was 24 % in our cohort (48/196) with 10 % (19/196) meeting the criteria for alcohol dependence. Alcohol consumption was significantly associated with pneumonia severity (r = 0.25, p < 0.001). Hazardous drinking (β-coefficient 10.12, 95 % CI 2.95-17.29, p = 0.006) and alcohol dependence (β-coefficient 12.89, 95 % CI 2.59-23.18, p = 0.014) were independent risk factors for pneumonia severity. Reported homelessness and men who have sex with men (MSM) status remained independent risk factors for more severe pneumonia after adjustment for the effects of alcohol. CONCLUSIONS In a cohort of HIV patients with pneumonia, presence of an AUD was an independent risk factor for pneumonia severity. Homelessness and MSM status were associated with greater pneumonia severity in AUD patients.

Abstract
Background The presence of Alcohol Use Disorder (AUD) complicates the medical conditions of patients and increases the difficulty of detecting and predicting the onset of septic shock for patients in the ICU. Methods We have developed a high-performance sepsis prediction algorithm, InSight, which outperforms existing methods for AUD patient populations. InSight analyses a combination of singlets, doublets, and triplets of clinical measurements over time to generate a septic shock risk score. AUD patients obtained from the MIMIC III database were used in this retrospective study to train InSight and compare performance with the Modified Early Warning Score (MEWS), the Simplified Acute Physiology Score (SAPS II), and the Systemic Inflammatory Response Syndrome (SIRS) for septic shock prediction and detection. Results From 4-fold cross validation, InSight performs particularly well on diagnostic odds ratio and demonstrates a relatively high Area Under the Receiver Operating Characteristic (AUROC) metric. Four hours prior to onset, InSight had an average AUROC of 0.815, and at the time of onset, InSight had an average AUROC value of 0.965. When applied to patient populations where AUD may complicate prediction methods of sepsis, InSight outperforms existing diagnostic tools. Conclusions Analysis of the higher order correlations and trends between relevant clinical measurements using the InSight algorithm leads to more accurate detection and prediction of septic shock, even in cases where diagnosis may be confounded by AUD. At 93% sensitivity, InSight reduces false alarms by >80% over other detection tools. InSight's diagnostic odds ratio is >30X those of MEWS, SAPS II, SIRS for detection. InSight outperforms comparable methods for septic shock prediction hours before onset.

Abstract
BACKGROUND Shoulder arthroplasty is becoming increasingly popular in the United States. Given the high prevalence of alcohol abuse and its implications in postoperative morbidity and the increasing incidence of shoulder arthroplasty, it is prudent to explore the effect of alcohol use disorders (AUDs) in this patient population. In this study, we considered numerous outcome variables, including perioperative complications, in-hospital death, prolonged hospital stay, and nonroutine discharge. METHODS Using the Nationwide Inpatient Sample, we performed a retrospective cohort study to identify a population of 422,371 adults (≥18 years old) undergoing total shoulder arthroplasty or hemiarthroplasty between January 1, 2002, and December 31, 2011. We then further subdivided this cohort into those who were classified as having AUDs and those who did not. Comparisons of early postoperative outcome measures were performed by bivariate and multivariable analyses with logistic regression modeling. RESULTS Compared with those without AUDs, patients undergoing shoulder arthroplasty with a preexisting AUD have a greater likelihood to experience death, pneumonia, deep venous thrombosis, acute renal failure, transfusion, prolonged length of stay, and nonroutine discharge irrespective of age, gender, race, and other medical comorbidities. Patients with a preexisting AUD are 2.7 times more likely to experience perioperative complications after shoulder arthroplasty. CONCLUSION Patients undergoing shoulder arthroplasty with a preexisting AUD have a greater likelihood of perioperative complications and health care resource utilization after shoulder arthroplasty. Presurgical alcohol screening may prove effective in identifying at-risk patients, and providing interventions before surgery may effectively limit the complication profile.

Abstract
AIMS Alcohol use disorders (AUD) have been associated with an increased risk of unplanned hospital readmissions (URA). We analyzed in a sample of 87 Spanish Hospitals if surgical patients with AUD had a higher risk of URA and if among patients with URA, those with AUD had an excess length of hospital stay, higher hospital expenses and increased risk of mortality. METHOD We analyzed data of patients who underwent surgical operations during the period between 2008 and 2010. URA was defined as unplanned readmissions during the first 30 days after hospital departure. The primary outcome was risk of URA in patients with AUD. Secondary outcomes were mortality, excess length of stay and over expenditure. RESULTS A total of 2,076,958 patients who underwent surgical operations were identified: 68,135 (3.3%) had AUD, and 62,045 (3.0%) had at least one URA. Among patients with AUD 4212 (6.2%) had at least one URA and among patients without AUD 57,833 (2.9%) had at least one URA. Multivariable analysis demonstrated that AUD was an independent predictor of developing URA (Odds ratio: 1.56; 95% CI: 1.50-1.62). Among surgical patients with URA, those with AUD had longer lengths of hospital stay (2.9 days longer), higher hospital costs (2885.8 Euros or 3858.3 US Dollars), higher risk of death (OR: 2.16, 95% CI: 1.92-2.44) and higher attributable mortality (11.2%). CONCLUSIONS Among surgical patients, AUD increase the risk of URA, and among patients with URA, AUD heighten the risk of in-hospital death, and cause longer hospital stays and over expenditures.

Abstract
The association between alcohol abuse and pneumonia has been recognized for more than two centuries and represents an enormous health burden worldwide. The first published notation of alcohol as a clinical risk factor for the development of pneumonia is now over 200 years old, and since then there have been over a 1,000 references in the medical literature confirming these observations. Even in this modern era of medicine pneumonia remains a common infection that afflicts over 450 million persons worldwide annually and causes 7 % of all deaths. When one considers that alcohol is the most commonly abused substance in the world, the enormous excessive burden that alcohol contributes to the morbidity and mortality of pneumonia represents a major public health consideration. In this chapter we review the foundational literature that has chronicled the evolution of our understanding of the association between pneumonia and alcohol abuse over the past century. In addition, we discuss some of the specific pathogens that are particularly associated with serious lung infections in individuals with alcohol use disorders. Finally, we consider some of the specific guidelines for the treatment and prevention of pneumonia in the setting of alcohol abuse.

Therefore, we assessed medical comorbidity with a clinical index to identify subgroups of alcoholic patients at high risk of premature death. METHODS Hospital-based cohort of alcohol-dependent patients admitted for detoxification between 1999 and 2008 in Barcelona, Spain. At admission, sociodemographic characteristics and a history of alcohol dependence and abuse of illegal drugs were obtained through clinical interviews and questionnaires. Medical comorbidity was assessed with the Cumulative Illness Rating Scale (Substance Abuse) (CIRS-SA). Dates and causes of death were obtained from clinical records and death registers. Survival was analyzed using Kaplan-Meier methods, and Cox regression models were used to analyze the risk factors for premature death. RESULTS Median age of the patients (686 total, 79.7% men) was 43.5 years (interquartile range [IQR], 37.8 to 50.4), average alcohol consumption was 200 g/d (IQR, 120 to 280 g/d), and duration of alcohol use disorder was 18 years (IQR, 11 to 24). Medical comorbidity by CIRS-SA at admission showed that the organs/systems most affected were liver (99%), respiratory (86%), and cardiovascular (58%). After median follow-up of 3.1 years (IQR, 1.5 to 5.1), 78 (11.4%) patients died with a mortality rate of 3.28 × 100 person-years; according to Kaplan-Meier estimates, 50% (95% confidence interval [95% CI], 24 to 69%) of patients with severe medical comorbidity died in the first decade after treatment. In multivariate analysis, severe medical comorbidity (hazard ratio [HR], 5.5; 95% CI, 3.02 to 10.07) and being treated with methadone at admission (HR, 2.60; 95% CI, 1.50 to 4.51) were independent risk factors for premature death. CONCLUSIONS Systematic assessment of alcohol-related organ damage is relevant for the identification and treatment of those at increased risk of death.

[PMID: 23627868 DOI: 10.1111/add.12231] [Citation(s) in RCA: 188] [Impact Index Per Article: 17.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2013] [Revised: 03/26/2013] [Accepted: 04/23/2013] [Indexed: 01/16/2023]
Abstract
AIMS To conduct a systematic review and meta-analysis on all-cause mortality in people with alcohol use disorders. METHODS Using the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) guidelines, studies were identified through MEDLINE, EMBASE, and Web of Science up to August, 2012. Prospective and historical cohort studies including a comparison of alcohol use disorder with a control group investigating all-cause mortality risk were included. RESULTS This meta-analysis included 81 observational studies with 221 683 observed deaths among 853 722 people with alcohol use disorder. In men, the relative risk (RR) among clinical samples was 3.38 (95% confidence interval [CI]: 2.98-3.84); in women it was 4.57 (95% CI: 3.86-5.42). Alcohol use disorders identified in general population surveys showed a twofold higher risk compared with no alcohol use disorder in men; no data were available for women. RRs were markedly higher for those ≤40 years old (ninefold in men, 13-fold in women) while still being at least twofold among those aged 60 years or older. CONCLUSIONS Mortality in people with alcohol use disorders is markedly higher than thought previously. Women have generally higher mortality risks than men. Among all people with alcohol use disorders, people in younger age groups and people in treatment show substantially higher mortality risk than others in that group.

Health care-associated infections in surgical patients undergoing elective surgery: are alcohol use disorders a risk factor? J Am Coll Surg 2012; 215:229-36. [PMID: 22727411 DOI: 10.1016/j.jamcollsurg.2012.04.015] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2011] [Revised: 02/17/2012] [Accepted: 04/04/2012] [Indexed: 10/28/2022]
Abstract
BACKGROUND Health care-associated infections (HAI) result in 100,000 deaths/year. Alcohol use disorders (AUD) increase the risk of community-acquired infections and HAI. Small studies have shown that AUD increase the risk of HAI and surgical site infections (SSI). We sought to determine the risk of HAI and SSI in surgical patients undergoing elective inpatient joint replacement, coronary artery bypass grafting, laparoscopic cholecystectomy, colectomy, and hernia repair. STUDY DESIGN The Nationwide Inpatient Sample was analyzed (years 2007 and 2008). HAI were defined as health care-associated pneumonia, sepsis, SSI, and urinary tract infection. Primary outcomes were risk of HAI and SSI in patients with AUD. Secondary outcomes were mortality and hospital length of stay in patients with HAI and SSI, alpha = 10(-6). RESULTS There were 1,275,034 inpatient admissions analyzed; 38,335 (3.0%) cases of HAI were documented, and 5,756 (0.5%) cases of SSI were identified. AUD was diagnosed in 11,640 (0.9%) of cases. Multivariable analysis demonstrated that AUD was an independent predictor of developing HAI: odds ratio (OR) 1.70, p < 10(-6), and this risk was independent of type of surgery. By multivariable analysis, the risk of SSI in patients with AUD was also higher: OR 2.73, p < 10(-6). Hospital mortality in patients with HAI or SSI was not affected by AUD. However, hospital length of stay was longer in patients with HAI who had AUD (multivariable analysis 2.4 days longer, p < 10(-6)). Among patients with SSI, those with AUD did not have longer hospital length of stay. CONCLUSIONS Patients with AUD who undergo a variety of elective operations have an increased risk of infectious postoperative morbidity.
