Abstract
INTRODUCTION The health effects of alcohol are well established but the influence on pulmonary function remains debated. Studies indicate that small amounts of alcohol are beneficial and heavy consumption is harmful, suggesting a U-shaped association. Our objective is to determine whether there is an association between alcohol intake and changes in pulmonary function parameters, exploring the potential protective effect of moderate alcohol consumption and the harm caused by heavy drinking. METHODS A comprehensive search from PubMed, Embase, Cochrane and CINAHL was carried out, and studies were evaluated using the JBI methodological framework for scoping reviews. Two independent reviewers conducted parallel screening and data extraction. A data extraction form was utilised to organise key themes, with qualitative analysis and visual representation of the results. RESULTS Among 4427 screened abstracts, 179 underwent full-text review, resulting in 30 eligible studies. Of these, 10 showed a negative effect, nine reported no impact, nine exhibited a positive effect and two indicated a nonlinear U-shaped association between alcohol consumption and pulmonary function parameters. CONCLUSION While the U-shaped curve hypothesis remains unconfirmed by the current literature, there are notable associations. Heavy alcohol consumption appears to negatively affect pulmonary function, while low to moderate intake shows a positive influence in included studies. However, the diversity in study quality, the nonstandardised alcohol intake quantification and the confounding role of smoking challenge definitive conclusions. The need for consistent, long-term international studies is evident to further explore this relationship while addressing the complex interplay between alcohol and smoking.

ENVIRONMENTAL HEALTH INSIGHTS 2022; 16:11786302221145429. [PMID: 36569771 PMCID: PMC9768828 DOI: 10.1177/11786302221145429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 11/29/2022] [Indexed: 06/17/2023]
Abstract
BACKGROUND Street sweepers are exposed to a variety of risk factors such as dust, bioaerosols, and volatile organic matter, which are responsible for the development of various respiratory symptoms and lung function impairments. However, there is a limited data on the prevalence of respiratory symptoms and associated factors among street sweepers in Ethiopia, especially in the study area. OBJECTIVE This study aimed to assess the prevalence of respiratory symptoms and associated factors among street sweepers in Gondar town, northwest Ethiopia, in 2021. METHODS Using simple random sampling technique, a total of 391 workers were selected between August 10 and September 15, 2021. The data was entered and analyzed using the Epi Info Version 7 and Statistical Package for Social Science (SPSS) 22 software, respectively. Descriptive statistics, bivariable, and multivariable logistic regression model were used. P ⩽ .05 and adjusted odds ratios (AOR) with 95% confidence interval (CI) were used to declare the statistical significance. RESULT A total of 391 respondents, with a response rate of 99.2% participated. The prevalence of respiratory symptoms among street sweepers was 35.3% (95% CI: 30.2, 40.5). History of respiratory illness (AOR = 7.75, (95% CI: 3.45, 17.45), washing personal protective equipments (PPE) after use (AOR = 4.77; 95% CI: 2.02, 11.28), previous work in cement (AOR = 3.10, 95% CI: 1.32, 7.34), and flour factories (AOR = 2.13, 95% CI: 2.02, 4.43), and alcohol drinking (AOR = 3.77, 95% CI: 1.94, 7.29) were associated with respiratory symptom among street sweepers. CONCLUSION The overall prevalence of respiratory symptoms among street sweepers was 35.3%. Previous respiratory illness, washing personal protective equipment after use, previous work in a cement and flour factory, and drinking alcohol were independently associated with respiratory symptoms. To reduce the respiratory symptoms among street sweeper, it is advisable implementing safe work practice measures and behavioral changes among workers.

Abstract
BACKGROUND The global prevalence of occupational noise-induced hearing loss ranges between 16% and 24%. The wood and metalwork industries have recently expanded in Ethiopia. This study aims to determine the level of noise exposure and the prevalence of self-reported hearing impairments and associated risk factors among metal and woodworkers in Gondar town Ethiopia. MATERIAL AND METHODS An institutional-based cross-sectional study was conducted on 580 metal and woodwork workers from February10 to March 25/2020. The data were collected through an interviewer-led questioner and the noise level measurement. Multivariate Poisson regression models were used. P-values less than .05 and adjusted prevalence ratios with 95%CI were used to declare the presence and strength of an association respectively. RESULT The mean (SD) average noise exposure level in the wood and metalworking industries was 96.9 ± 3.5 dBA and 96.2 ± 4 dBA, respectively. The overall prevalence of self-reported hearing impairment was 20.7% [95%CI: (17.4-24)]. In an adjusted Poisson regression, listening to music with earphones for more than 2 hours per day (PR = 2.95, 95%CI: 1.32, 6.21) and listening to music at maximum volume (PR = 2.24, 95%CI: 1.05, 4.79) were associated with hearing impairments. CONCLUSION The majority of workers are exposed to noise levels that exceed OSHA's permissible exposure limit value. A hearing conservation program should be implemented to reduce noise exposure levels in the wood and metal work industries. Workers should be aware of the duration and volume of recreational noise exposure.

Abstract
Neuropathic pain in spinal cord injury (SCI) is associated with inflammation in both the peripheral and central nervous system (CNS), which may contribute to the initiation and maintenance of persistent pain. An understanding of factors contributing to neuroinflammation may lead to new therapeutic targets for neuropathic pain. Moreover, novel circulating biomarkers of neuropathic pain may facilitate earlier and more effective treatment. MicroRNAs (miRNAs) are short, non-coding single-stranded RNA that have emerged as important biomarkers and molecular mediators in physiological and pathological conditions. Using a genome-wide miRNA screening approach, we studied differential miRNA expression in plasma from 68 healthy, community-dwelling adults with and without SCI enrolled in ongoing clinical studies. We detected 2367 distinct miRNAs. Of these, 383 miRNAs were differentially expressed in acute SCI or chronic SCI versus no SCI and 71 were differentially expressed in chronic neuropathic pain versus no neuropathic pain. We selected homo sapiens (hsa)-miR-19a-3p and hsa-miR-19b-3p for additional analysis based on p-value, fold change, and their known role as regulators of neuropathic pain and neuroinflammation. Both hsa-miR-19a-3p and hsa-miR-19b-3p levels were significantly higher in those with chronic SCI and severe neuropathic pain versus those with chronic SCI and no neuropathic pain. In confirmatory studies, both hsa-miR-19a-3p and hsa-miR-19b-3p have moderate to strong discriminative ability to distinguish between those with and without pain. After adjusting for opioid use, hsa-miR-19b-3p levels were positively associated with pain interference with mood. Because hsa-miR-19 levels have been shown to change in response to exercise, folic acid, and resveratrol, these studies suggest that miRNAs are potential targets of therapeutic interventions.

Abstract
Smoking cessation aids in restoring lung function. However, whether long-term cessation can fully restore lung function has not been studied thoroughly, especially in Asian countries. This study aimed to evaluate the association between smoking cessation status and obstructive spirometry pattern among Koreans aged 40-79 years. In total, 6298 men and 8088 women aged 40-79 years from the Korea National Health and Nutrition Examination Survey (2015-2019) were analyzed for smoking cessation status, including the duration after quitting. Current-smokers showed a higher likelihood of having an obstructive spirometry pattern than never-smokers among both men (odds ratio [OR]: 3.15, 95% confidence interval [CI]: 2.32-4.29) and women (OR: 2.60, 95% CI: 1.59-4.23). In men, the effect tended to decrease with longer duration after cessation, but male ex-smokers who had quit smoking ≥ 20 years ago still showed a higher likelihood of having an obstructive spirometry pattern than male never-smokers (OR: 1.40, 95% CI: 1.05-1.89). In female ex-smokers, there was no significant association with the obstructive spirometry pattern, compared to that in female never-smokers. This study emphasizes the benefits of smoking cessation, possibility of long-lasting harm to lung function due to tobacco smoking, and importance of smoking prevention.

Abstract
CONTEXT Chronic obstructive lung disease (COPD) is a progressive lung disease characterized by persistent airflow limitation. An increasing amount of evidence suggests an effect of dietary quality on the risk of COPD in the general population and pulmonary function decline in patients with COPD. OBJECTIVE The association of dietary intake and nutrient status with COPD risk and onset, as well as pulmonary function decline (change in forced expiratory volume in 1 second, forced vital capacity, or the ratio of the former to the latter) in patients with COPD was investigated in this systematic review. DATA SOURCES The PubMed database was searched by combining terms of pulmonary function or COPD with diet, nutrient status, or nutritional supplementation. DATA EXTRACTION Original studies and systematic reviews and meta-analyses were included. Articles obtained were independently screened for relevance on the bases of title and abstract by 2 researchers. Eventually, 89 articles were included in the analysis. RESULTS The unhealthy Western-style diet is associated with an increased risk of COPD and an accelerated decline of pulmonary function. Intake of fruit, vegetables, dietary fibers, vitamins C and E, polyphenols, and β-carotene were individually associated with lower COPD risk, whereas consumption of processed meat was associated with higher COPD risk. Data on the effect of dietary quality on pulmonary function decline in patients with COPD are limited and inconsistent. Strong evidence for beneficial effects on pulmonary function decline was found only for vitamin D supplementation. CONCLUSION Considering the increasing burden of COPD, more attention should be given to dietary quality as a modifiable factor in disease development and progression in patients with COPD.

Abstract
The overall effect of lifestyle habits, such as alcohol consumption, on general health remains controversial and it is important to clarify how such habits affect aging-related health impairments. To discover novel impacts of lifestyle on general health, we employed a mathematical approach to perform a comprehensive, unbiased, cross-sectional analysis of data from 6036 subjects who participated in a Japanese health checkup. Notably, we found that moderate alcohol consumption was positively correlated with lung function, muscle mass, and strength. Health checkup data were collected periodically from the same subjects. These people were light to moderate drinkers who had high health awareness and were basically free of major underlying diseases. We next analyzed 5 years of data from 1765 of these subjects. We found that higher baseline alcohol consumption, as well as increased alcohol intake over 5 years attenuated time-related deterioration of forced vital capacity without affecting total lung volume. This effect was independent of smoking. Our study suggests a possible protective effect of moderate amounts of alcohol on lung function, due to increased muscle mass/strength and forced vital capacity.

Abstract
B cell-mediated autoimmunity may contribute to poor neurological outcomes after spinal cord injury (SCI). B cell-activating factor (BAFF) is a key cytokine involved in B cell development, proliferation, activation, and survival whose expression is elevated in men with chronic SCI. The aim of this study was to assess factors associated with circulating BAFF in non-ambulatory males with chronic SCI. We assessed the association between clinical and demographic factors, health habits, and circulating BAFF levels in a convenience sample of 43 non-ambulatory men with chronic spinal cord injury (≥ 1 year post-injury). Serum BAFF and total testosterone levels were quantified by enzyme-linked immunosorbent assay. Body composition was determined by whole body dual-energy X-ray absorptiometry. In multivariable models, active smokers had significantly greater BAFF levels than former/nonsmokers (871 pg/mL vs. 665 pg/ml, p = 0.002). BAFF decreased 36 ± 11.1 pg/mL for every 1 ng/mL increase in total testosterone (p = 0.002). This model explained 41% of the variation in circulating BAFF levels (model p < 0.0001). Our findings suggest that modifiable health habits may be associated with elevated BAFF levels in men with non-ambulatory chronic SCI. Further, the significant and independent negative association between testosterone levels and BAFF would suggest a link between androgen deficiency and autoimmunity observed in SCI via modulation of BAFF and B cell numbers. This points toward BAFF as a potential biomarker of injury severity and a target of therapies designed to reduce neuroinflammation and improve neurological outcomes after SCI.

Abstract
Little is known about the alcohol habits of people with advanced lung disease. Following lung transplantation, patients are asked to abstain from or minimize alcohol use. The aim of this investigation was to assess alcohol use in a cohort of patients with advanced lung disease undergoing evaluation for lung transplant. This is a prospective observational investigation comparing patient self-report of alcohol use with their responses on the Alcohol Use Disorders Identification Test (AUDIT), and alcohol biomarkers collected at the time of transplant. There were 86 included in the cohort, 34% currently using alcohol, 13% had AUDIT scores >3, and 10% had positive results for alcohol biomarkers at the time of transplantation. Patients with evidence of recent alcohol use prior to lung transplant surgery had a 1.5-fold increase in hospital length of stay following lung transplant (P = .028), spent 3 times as long on mechanical ventilation after transplant, and required intensive care unit monitoring nearly 3 times longer than those without recent alcohol use (P = .008). There were no differences in primary graft dysfunction, although several patients with recent alcohol use had post-transplant atrial arrhythmias, acute kidney injury, and acute cellular rejection. Abstaining from alcohol use may optimize outcomes following lung transplant.

Abstract
Alcohol intake has been inconsistently associated with lung function levels in cross-sectional studies. The goal of our study was to determine whether longitudinally assessed light-to-moderate alcohol intake is associated with levels and decline of lung function. We examined data from 1333 adult participants in the population-based Tucson Epidemiological Study of Airway Obstructive Disease. Alcohol intake was assessed with four surveys between 1972 and 1992. Subjects who completed at least two surveys were classified into longitudinal drinking categories ("never", "inconsistent", or "persistent drinker"). Spirometric lung function was measured in up to 11 surveys between 1972 and 1992. Random coefficient models were used to test for differences in lung function by drinking categories. After adjustment for sex, age, height, education, BMI categories, smoking status, and pack-years, as compared to never-drinkers, persistent drinkers had higher FVC (coefficient: 157 mL, p < 0.001), but lower FEV1/FVC ratio (-2.3%, p < 0.001). Differences were due to a slower decline of FVC among persistent than among never-drinkers (p = 0.003), and these trends were present independent of smoking status. Inconsistent drinking showed similar, but weaker associations. After adjustment for potential confounders, light-to-moderate alcohol consumption was associated with a significantly decreased rate of FVC decline over adult life.

Abstract
Background Co-exposure to cigarette smoke and alcohol leads to the generation of high concentrations of acetaldehyde and malondialdehyde in the lung. These aldehydes being highly electrophilic in nature react with biologically relevant proteins such as surfactant protein D (SPD) through a Schiff base reaction to generate SPD adducted malondialdehyde-acetaldehyde adduct (SPD-MAA) in mouse lung. SPD-MAA results in an increase in lung pro-inflammatory chemokine, keratinocyte chemoattractant (KC), and the recruitment of lung lavage neutrophils. Previous in vitro studies in bronchial epithelial cells and macrophages show that scavenger receptor A (SR-A1/CD204) is a major receptor for SPD-MAA. No studies have yet examined the in vivo role of SR-A1 in MAA-mediated lung inflammation. Therefore, we hypothesize that in the absence of SR-A1, MAA-induced inflammation in the lung is reduced or diminished. Methods To test this hypothesis, C57BL/6 WT and SR-A1 KO mice were nasally instilled with 50 μg/mL of SPD-MAA for 3 weeks (wks). After 3 weeks, bronchoalveolar lavage (BAL) fluid was collected and assayed for a total cell count, a differential cell count and CXCL1 (KC) chemokine. Lung tissue sections were stained with hematoxylin and eosin (H&E) and antibodies to MAA adduct. Results Results showed that BAL cellularity and influx of neutrophils were decreased in SR-A1 KO mice as compared to WT following repetitive SPD-MAA exposure. MAA adduct staining in the lung epithelium was decreased in SR-A1 KO mice. In comparison to WT, no increase in CXCL1 was observed in BAL fluid from SR-A1 KO mice over time. Conclusions Overall, the data demonstrate that SR-A1/CD204 plays an important role in SPD-MAA induced inflammation in lung.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is the third most common cause in the United States of hospital readmission within 30 days of discharge. Readmissions, which are attributed to poor quality of care, are costly. We examined the factors associated with 30-day readmission in patients hospitalized with acute exacerbation of COPD. Our hypothesis was that early readmissions among patients with COPD are related to patient factors rather than system or provider factors. METHODS We performed a retrospective chart review of all patients discharged from our facility from June 2010 to May 2011 with a primary discharge diagnosis of COPD. Detailed patient characteristics were obtained from the electronic medical record. Patients were followed for 30 days post-discharge date. We examined the differences in baseline characteristics of patients readmitted within 30 days and those not readmitted. RESULTS A total of 160 patients were admitted for 192 hospitalizations during the study period; 31 patients (19.4%) were readmitted within 30 days. Patients who were readmitted did not differ from those who were not readmitted of the following factors: baseline medication use, length of stay, and outpatient follow-up postdischarge. Readmitted patients were more likely to be black, to have coronary artery disease, to have a history of alcohol abuse, and to be on supplemental oxygen. Multivariate analysis showed a 2.17 odds of 30-day readmission (95% CI, 1.16-4.09) in patients with alcohol abuse, and 2.52 (95% CI, 1.18-5.38) in those on supplemental oxygen. CONCLUSION In our study population, 19.4% of acute exacerbation COPD patients were readmitted within 30 days. Patient factors (such as alcohol abuse and advanced disease) were associated with 30-day readmission.

Abstract
OBJECTIVE To investigate longitudinal risk factors of hospitalization for circulatory and pulmonary diseases among veterans with chronic spinal cord injury (SCI). Circulatory and respiratory system illnesses are leading causes of death in patients with chronic SCI, yet risk factors for related hospitalizations have not been characterized. DESIGN Prospective cohort study. SETTING Veterans Affairs (VA) Boston Healthcare System, Boston, Massachusetts. PARTICIPANTS/DATA SOURCES: Veterans (N=309) greater than or equal to 1 year post-SCI from the VA Boston Chronic SCI cohort who completed a health questionnaire and underwent spirometry at study entry. Baseline data were linked to 1996 through 2003 hospitalization records from the VA National Patient Care Database. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Cardiopulmonary hospital admissions, the predictors of which were assessed by multivariate Cox regression. RESULTS Of 1478 admissions observed, 143 were a result of cardiopulmonary (77 circulatory and 66 respiratory) illnesses. Independent predictors were greater age (3% increase/y), hypertension, and the lowest body mass index quintile (<22.4 kg/m2). A greater percentage-predicted forced expiratory volume in 1 second was associated with reduced risk. SCI level and completeness of injury were not statistically significant after adjusting for these risk factors. CONCLUSIONS Cardiopulmonary hospitalization risk in persons with chronic SCI is related to greater age and medical factors that, if recognized, may result in strategies for reducing future hospitalizations.

Abstract
UNLABELLED Osteoporosis is a well acknowledged complication of spinal cord injury. We report that motor complete spinal cord injury and post-injury alcohol consumption are risk factors for hospitalization for fracture treatment. The clinical assessment did not include osteoporosis diagnosis and treatment considerations, indicating a need for improved clinical protocols. INTRODUCTION Treatment of osteoporotic long bone fractures often results in lengthy hospitalizations for individuals with spinal cord injury. Clinical features and factors that contribute to hospitalization risk have not previously been described. METHODS Three hundred and fifteen veterans > or = 1 year after spinal cord injury completed a health questionnaire and underwent clinical exam at study entry. Multivariate Cox regression accounting for repeated events was used to assess longitudinal predictors of fracture-related hospitalizations in Veterans Affairs Medical Centers 1996-2003. RESULTS One thousand four hundred and eighty-seven hospital admissions occurred among 315 participants, and 39 hospitalizations (2.6%) were for fracture treatment. Median length of stay was 35 days. Fracture-related complications occurred in 53%. Independent risk factors for admission were motor complete versus motor incomplete spinal cord injury (hazard ratio = 3.73, 95% CI = 1.46-10.50). There was a significant linear trend in risk with greater alcohol consumption after injury. Record review indicated that evaluation for osteoporosis was not obtained during these admissions. CONCLUSIONS Assessed prospectively, hospitalization in Veterans Affairs Medical Centers for low-impact fractures is more common in motor complete spinal cord injury and is associated with greater alcohol use after injury. Osteoporosis diagnosis and treatment considerations were not part of a clinical assessment, indicating the need for improved protocols that might prevent low-impact fractures and related admissions.

Abstract
BACKGROUND Alcohol has been associated with COPD-related mortality but has not yet been demonstrated to be an independent risk factor for COPD exacerbation. Our objective was to evaluate the association between alcohol consumption and the subsequent risk of COPD exacerbation. METHODS A prospective cohort study of general medicine outpatients seen at one of seven Veterans Affairs (VA) medical centers who returned health screening questionnaires. Three screening questionnaires, AUDIT-C (0 to 12 points), CAGE (0 to 4 points), and a single item about the frequency of drinking six or more drinks on an occasion (binge drinking), were used to classify alcohol consumption. The main outcome, COPD exacerbation, was based on primary VA discharge diagnosis (International Classification of Diseases, Ninth Revision) or outpatient diagnosis of COPD accompanied by prescriptions for either antibiotics or prednisone within 2 days. RESULTS Among the 30,503 patients followed up for a median of 3.35 years, those patients with AUDIT-C scores > or = 6, CAGE scores > or = 2, or who reported binge drinking at least weekly were at an increased risk of COPD exacerbation in age-adjusted analysis. Adjusted hazard ratios were 1.4 (95% confidence interval [CI], 1.1 to 1.7) for AUDIT-C score > or = 6, 1.4 (95% CI, 1.3 to 1.5) for CAGE score > or = 2, and 1.6 (95% CI, 1.2 to 2.2) for those who reported binge drinking daily or almost daily. However, with adjustment for measures of tobacco use, the association between alcohol consumption and increased risk of COPD exacerbation was no longer evident. CONCLUSIONS Alcohol consumption, whether quantified by AUDIT-C, CAGE score, or binge drinking, was not associated with an increased risk of COPD exacerbation independent of tobacco use.

Abstract
1. Impaired lung function has been reported to be associated with mortality from all causes, cardiovascular disease (CVD) and aortic pulse wave velocity (PWV). The aim of the present study was to examine the association between impaired lung function and atherosclerotic risk factors, including PWV, blood pressure, lipids, smoking and alcohol intake, among Japanese Americans. 2. The study subjects were 678 adult Japanese Americans who participated in CVD screening conducted under the Seattle Nikkei Health Study. Subjects with abnormal lung function were defined as those with forced vital capacity (FVC%) < 80% of predicted or forced expiratory volume in 1 s (FEV1%) < 80% of predicted. We conducted logistic regression analyses by using abnormal lung function as dependent variables. 3. The significant predictors positively associated with abnormal FVC% were age (60 years or older) and hypertension. Being a current drinker or an ex-drinker was independently and negatively associated with abnormal FVC%. The significant predictors positively associated with abnormal FEV1% were age (60 years or older), sex (male), hypertension and being a current smoker. Being a current drinker was independently and negatively associated with abnormal FEV1%. 4. In conclusion, the present study does not support the previously reported association of abnormal lung function with PWV. However, our findings imply that light and moderate drinking may be a protective factor of lung function and that hypertension and smoking may impair lung function.

Abstract
The volatility of alcohol promotes the movement of alcohol from the bronchial circulation across the airway epithelium and into the conducting airways of the lung. The exposure of the airways through this route likely accounts for many of the biologic effects of alcohol on lung airway functions. The effect of alcohol on lung airway functions is dependent on the concentration, duration, and route of exposure. Brief exposure to mild concentrations of alcohol may enhance mucociliary clearance, stimulates bronchodilation, and probably attenuates the airway inflammation and injury observed in asthma and chronic obstructive pulmonary disease (COPD). Prolonged and heavy exposure to alcohol impairs mucociliary clearance, may complicate asthma management, and likely worsens outcomes including lung function and mortality in COPD patients. Nonalcohol congeners and alcohol metabolites act as triggers for airway disease exacerbations especially in atopic asthmatics and in Asian populations who have a reduced capacity to metabolize alcohol. Research focused on the mechanisms of alcohol-mediated changes in airway functions has identified specific mechanisms that mediate alcohol effects within the lung airways. These include prominent roles for the second messengers calcium and nitric oxide, regulatory kinases including PKG and PKA, alcohol- and acetaldehyde-metabolizing enzymes such as aldehyde dehydrogenase 2. The role alcohol may play in the pathobiology of airway mucus, bronchial blood flow, airway smooth muscle regulation, and the interaction with other airway exposure agents, such as cigarette smoke, represents opportunities for future investigation.

Abstract
Understanding of the relation between the alcoholic consumption and the development of pancreatitis should help in defining the alcoholic etiology of pancreatitis. Although the association between alcohol consumption and pancreatitis has been recognized for over 100 years, it remains still unclear why some alcoholics develop pancreatitis and some do not. Surprisingly little data are available about alcohol amounts, drinking patterns, type of alcohol consumed and other habits such as dietary habits or smoking in respect to pancreatitis preceding the attack of acute pancreatitis or the time of the diagnosis of chronic pancreatitis. This review summarizes the current knowledge. Epidemiological studies clearly show connection between the alcohol consumption in population and the development of acute and chronic pancreatitis. In the individual level the risk to develop either acute or chronic pancreatitis increases along with the alcohol consumption. Moreover, the risk for recurrent acute pancreatitis after the first acute pancreatitis episode seems also to be highly dependent on the level of alcohol consumption. Abstaining from alcohol may prohibit recurrent acute pancreatitis and reduce pain in chronic pancreatitis. Therefore, all the attempts to decrease alcohol consumption after acute pancreatitis and even after the diagnosis of chronic pancreatitis should be encouraged. Smoking seems to be a remarkable co-factor together with alcohol in the development of chronic pancreatitis, whereas no hard data are available for this association in acute pancreatitis. Setting the limits for accepting the alcohol as the etiology cannot currently be based on published data, but rather on the 'political' agreement.

Abstract
BACKGROUND To our knowledge, there are no previous data on drinking problems in patients with pneumoconiosis. The aim of this study was to examine drinking patterns and the impact of drinking on lung function and health-related quality of life (HRQOL) in Chinese patients with pneumoconiosis. METHODS Three hundred patients with pneumoconiosis were recruited from a community-based case registry. The HRQOL was measured with the St. George's Respiratory Questionnaire (SGRQ). Pulmonary function, comorbidity, and psychosocial variables were also assessed. The alcohol use of the patients was evaluated with the Alcohol Use Disorders Identification questionnaire. RESULTS Of the 300 patients, 72.3% (217) reported that they had not consumed any alcohol during the past year, whereas 83 patients (27.7%) did report drinking alcohol. In the drinking group, 88.0% (73) consumed <7 standard drinks per week, and none of them exceeded the safety limit of 21 standard drinks per week. The drinking group (n = 83) was younger, had less concurrent medical diseases, and lower (i.e., better) unadjusted SGRQ symptom, activity, impact, and total scores than the nondrinking group (n = 217). The SGRQ scores, which were adjusted for age, duration of occupation, concurrent medical diseases, smoking status, and forced expiratory volume in 1 sec predicted tests (FEV1%), remained significantly lower for the drinking group. Although the drinking group had a higher unadjusted FEV1% predicted, the difference between the FEV1% of the two groups, after adjustment for covariates, was of borderline significance only. CONCLUSIONS Most Chinese patients with pneumoconiosis in this study did not consume alcohol, and among those who did, the level of alcohol consumption was low. This low level of alcohol consumption was associated with a better HRQOL and possibly with better lung function.

Abstract
BACKGROUND A relationship between pulmonary dysfunction and cardiovascular mortality has been described. The mechanism responsible for the relationship remains largely unknown. METHODS The association between airflow obstruction and selected cardiovascular risk factors including gamma-glutamyl transferase (gamma-GT) and total homocysteine was analyzed cross-sectionally in 954 middle-aged men. Airflow obstruction was assessed with %FEV(1) (FEV(1)/FVC). RESULTS Serum gamma-GT and white blood cell (WBC) count were higher in subjects with airflow obstruction (%FEV(1)<70%) than in those without it (76.9+/-164.3 IU/L vs. 55.9+/-67.9 IU/L, P=0.030; 6290+/-1590/microL vs. 5590+/-1410/microL, P<0.001). Airflow obstruction was not associated with body mass index, total cholesterol, triglycerides, fasting glucose, or systolic blood pressure, but there was a marginal association with total homocysteine. In a logistic regression analysis adjusted for smoking status and alcohol consumption, the odds ratios (95% confidence interval) of Delta100 IU/L increase in gamma-GT and Delta1000/microL increase in WBC count for the presence of airflow obstruction were 1.20 (0.97-1.48, P=0.090) and 1.21 (1.02-1.44, P=0.036), respectively. CONCLUSIONS Airflow obstruction was associated with gamma-GT. The association was independent of alcohol consumption category, but was attenuated by the addition of cigarette smoking status.

Abstract
Little is known about the effect of moderate alcohol intake on lung function in the general population. Because moderate alcohol intake appears to reduce cardiovascular disease risk, we hypothesized that moderate alcohol intake is associated with better pulmonary function. To test this hypothesis, we examined the association between alcohol intake and pulmonary function, measured by spirometry, in a representative sample of U.S. adults who participated in the Third National Health and Nutrition Examination Survey. A stratified multistage clustered probability design was used to select a population-based sample. Data analyzed included alcohol intake, smoking status, education, body mass, sex, age, race, diabetes status, and CHF status. The Third National Health and Nutrition Examination Survey was conducted from 1988 to 1994 by the National Center for Health Statistics of the Centers for Disease Control and Prevention, Atlanta, GA. We analyzed data from 15,294 study participants who completed extensive questionnaires in the household and a comprehensive physical examination, including pulmonary function testing, either in the household or at a specially equipped mobile examination center. Low-to-moderate alcohol intake was not associated with reduced odds of obstructive lung function. In fact, increased odds for obstructive lung pattern were observed only in former heavy drinkers. In contrast, low-to-moderate alcohol intake was associated with better forced vital capacity and forced exhaled volume in 1s in the absence of obstruction, consistent with reduced odds for lung restriction. Using a logistic regression model, we found that individuals reporting alcohol consumption had a lower risk of lung restriction both before and after adjusting for confounding factors including smoking (P< or =.001). Alcohol intake-related reduced risk for restriction was associated with lower risk of CHF, diabetes, obesity, and lower markers of inflammation (white blood cell, fibrinogen, and C-reactive protein) consistent with less lung congestion, external restriction, and/or lung inflammation. Our analyses indicate that alcohol consumption, even at very modest intake levels, is associated with less lung restriction.

Abstract
The fate of a patient with acute pancreatitis largely depends on early recognition of the severity of the disease. Acute pancreatitis is severe when organ failure and/or pancreatic necrosis occur. Whereas simple and low cost parameters are available for the detection of organ failure, the detection and extent of pancreatic necrosis requires a costly contrast-enhanced computed tomography. This is not always available in all institutions. This review article which considers when the clinician should be concerned about his patient diagnosed with acute pancreatitis, summarizes possibilities for diagnosing clinical severe (that is organ failure) and radiological severe (that is the necrotizing form of the disease) pancreatitis using simple and inexpensive parameters which are available everywhere. At present, a CT scan should be performed in those patients with alcohol etiology, those admitted to hospital early (time interval between the onset of symptoms and admission to hospital of less than 24 h, those presenting with rebound tenderness and/or guarding, a lipase >1,000 U/l, as well as a raised hematocrit and blood glucose. The evaluation, furthermore, shows that some parameters have a sufficiently high negative predictive value of >90%, which may render a contrast-enhanced CT scan unnecessary in the early stages, unless the patient fails to improve. These parameters include non-alcohol etiology, time interval between onset and admission to hospital longer than 24 h, no guarding or rebound tenderness on admission, low or normal hematocrit and nonelevated blood glucose. It is necessary to look further on simple low cost and more valid parameters on admission in order to reliably distinguish between necrotizing pancreatitis and interstitial pancreatitis.

Abstract
BACKGROUND Lung function is a strong predictor of cardiovascular and all-cause mortality. Previous studies suggest that alcohol exposure may be linked to impaired pulmonary function through oxidant-antioxidant mechanisms. Alcoholic beverages may be an important source of oxidants and antioxidants. We analyzed the relation of beverage-specific alcohol intake with forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) in a random sample of 1555 residents of Western New York, USA. METHODS We expressed pulmonary function as percent of predicted normal FEV1 (FEV1%) and FVC (FVC%) after adjustment for height, age, gender, and race. To obtain information on alcohol intake we used a questionnaire that reliably queries total alcohol and beverage-specific recent (past 30 days) and lifetime alcohol consumption. RESULTS Using multiple linear regression analysis after adjustment for covariates (pack-years of smoking, weight, smoking status, education, nutritional factors, and for FEV1%, in addition, eosinophil count), we observed no significant correlation between total alcohol intake and lung function. However, we found positive associations of recent and lifetime wine intake with FEV1% and FVC%. When we analyzed white and red wine intake separately, the association of lung function with red wine was weaker than with white wine. CONCLUSION While total alcohol intake was not related to lung function, wine intake showed a positive association with lung function. Although we cannot exclude residual confounding by healthier lifestyle in wine drinkers, differential effects of alcoholic beverages on lung health may exist.

Abstract
BACKGROUND Lung function is a strong predictor of cardiovascular and all-cause mortality. Previous studies suggest that alcohol exposure may be linked to impaired pulmonary function through oxidant-antioxidant mechanisms. Alcohol may be an important source of oxidants; however, wine contains several antioxidants. In this study we analyzed the relation of beverage specific alcohol intake with forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) in a random sample of 1555 residents of Western New York, USA. METHODS We expressed pulmonary function as percent of predicted normal FEV1 (FEV1%) and FVC (FVC%) after adjustment for height, age, gender and race. To obtain information on alcohol intake we used a questionnaire that reliably queries total alcohol and beverage specific recent (past 30 days) and lifetime alcohol consumption. RESULTS Using multiple linear regression analysis after adjustment for covariates (pack-years of smoking, weight, smoking status, education, nutritional factors and for FEV1%, in addition, eosinophil count), we observed no significant correlation between total alcohol intake and lung function. However, we found positive associations of recent and lifetime wine intake with FEV1% and FVC%. When we analyzed white and red wine intake separately, the association of lung function with red wine was weaker than for white wine. CONCLUSION While total alcohol intake was not related to lung function, wine intake showed a positive association with lung function. Although we cannot exclude residual confounding by healthier lifestyle in wine drinkers, differential effects of alcoholic beverages on lung health may exist.

Abstract
BACKGROUND The aim of the study was to define the prognostic role of etiology in the course of acute pancreatitis. METHODS The study involved 208 consecutive patients with a first attack of acute pancreatitis. Etiology was biliary in 81 (39%) patients and alcohol abuse in 69 (33%); other etiologies were present in 16 (8%), and etiology remained unknown in 42 (20%). Etiology was correlated with the following parameters of severity of the disease: days in an intensive care unit (ICU); total hospital stay (THS); Ranson, Imrie, and Balthazar scores (contrast-enhanced computed tomography [CT] within 72 h of admission); indication of artificial ventilation, dialysis, or surgery; development of pancreatic pseudocysts; mortality. RESULTS Alcoholic etiology correlated significantly more frequently than other subgroups with necrotizing pancreatitis, need for artificial ventilation, and development of pancreatic pseudocysts. For the other parameters, there were no significant differences between the etiologies. CONCLUSION Patients with alcohol-induced acute pancreatitis should be given special attention because of the higher incidence of necrotizing pancreatitis and necessity for artificial ventilation. Whether the pronounced frequency of pseudocysts in alcoholics suggests progression to chronic pancreatitis has to be clarified in follow-up studies.

Abstract
Alcohol and smoking are two well-known health hazards. Alcohol and tobacco consumption are strongly correlated and heavy drinkers have more trouble quitting smoking than do light drinkers. Death from tobacco-related causes was more common than alcohol-related death in a follow-up study on patients admitted to an addiction programme for treatment of alcoholism and non-nicotine drug dependence. In British male doctors in the middle and elderly age group, a protective effect of light and moderate alcohol consumption (1-3 British units of alcohol per day) compared with abstinence has been shown in one large survey. This protective effect was shown in overall mortality as well as in mortality from respiratory disease. Higher alcohol intakes were associated with an increase in mortality. This characteristic U-formed, or J-formed, dose-response curve has been found in most studies with an apparent beneficial effect of modest alcohol intake and a harmful effect of high intakes. The anti-inflammatory effect of alcohol has been considered to be responsible for its limited protective effect on smoking-related lung function decline. Recently, a hitherto unconfirmed report suggests that the beneficial effect of alcohol on lung function in men is restricted to subjects with Lewis-negative blood group (10% of the Caucasian population). On the other hand, the protective effect in those individuals is large enough to be clinically relevant. Prospective investigations including both men and women are needed to elucidate which individuals have a protective effect of light and moderate alcohol intake. The major deleterious effect of smoking, including passive smoking, must be kept in mind-drinking alcohol surrounded by cigarette smoke might not be beneficial for respiratory health.

Abstract
OBJECTIVE To identify lifestyle, anthropometric, biochemical, and clinical characteristics associated with pulmonary function in elderly men. DESIGN Cross-sectional population-based study. PARTICIPANTS Japanese-American men (n=3,111) aged 71 to 93 years, who completed spirometry at the fourth examination of the Honolulu Heart Program (1991 to 1993). METHODS Pulmonary function measurements (FEV1 and FVC) were obtained using American Thoracic Society guidelines. Potential factors associated with pulmonary function were examined using Pearson correlation coefficients and general linear models. Age- and height-adjusted mean levels of FEV1 and FVC were compared across quintiles of continuous variables and by status of prevalent disease and medication or vitamin use. Stepwise multiple linear regression was used to identify factors independently associated with pulmonary function overall and among never smokers. RESULTS A number of correlates of pulmonary function were initially identified. In multivariate analyses, age, current smoking, pack-years of smoking, emphysema, asthma, wheezing without colds, subscapular skinfold thickness, ECG abnormality, heart rate, WBC count, and eosinophil count were all negatively and independently associated with FEV1, while height, grip strength, physical activity, and mean corpuscular hemoglobin concentration were positively associated. With a few exceptions, similar relations were observed with FVC and among never-smokers. CONCLUSION Cigarette smoking, respiratory symptoms and disease, and several cardiovascular risk factors were independently associated with pulmonary function in elderly Japanese-American men. In most cases, inadequate control for smoking does not appear to account for these associations. Results suggest that a number of factors that are correlates of FEV1 and FVC in younger age groups are also associated with pulmonary function beyond the age of 70 years.

Abstract
Epidemiological studies of the relationships between pulmonary function and reported alcohol intake showed inconsistent results. The use of biological markers of alcohol is needed. The objective of this study was to assess the relationships of alcohol consumption, assessed by a standardized questionnaire, and gamma-glutamyl transpeptidase (GGT), to forced expiratory volume in 1 sec (FEV1) level and decline over 10 years, in working men. Three hundred twenty-eight policemen aged 22-55 years were examined in 1980 (first survey) and again in 1990 (second survey). The two cross-sectional analyses used the 1980 data and the 1990 data separately. Longitudinal analysis used 1980 alcohol consumption and GGT values, and 10-year FEV1 decline. In both cross-sectional surveys, elevated alcohol consumption was significantly associated with impaired age-adjusted and height-adjusted FEV1. Further adjustment for smoking habit, education level, and asthmatic status did not alter these results. An increase of 25 g/day of alcohol was associated with 50.0 ml (95% confidence interval: 1.5 to 98.5) and 55.3 ml (95% confidence interval: 7.8 to 102.8) decrease of corresponding multivariate-adjusted FEV1 in 1980 and in 1990, respectively. GGT was also negatively associated with FEV1 in both cross-sectional surveys. Similar patterns of associations were also observed between vital capacity measurements and alcohol variables. In the longitudinal analysis, there was no relationship between either alcohol consumption or GGT and FEV1 decline. Findings suggest that alcohol consumption was associated with impaired lung function, but there was no evidence of accelerated FEV1 decline over 10 years related to alcohol consumption in this "healthy" population of middle-aged men.

Abstract
Increased inflammation of the peripheral airways has been implicated as a cause of pulmonary function impairment. However, little information is available on the correlation between subclinical decrements of pulmonary function and inflammation in asymptomatic individuals. A relationship between markers of inflammation and lung function may be useful in predicting the early onset of lung function impairment. The purpose of this study was to investigate the correlation of hematologic markers of inflammation and spirometry in asymptomatic smokers and nonsmokers. The specific objectives of this study were twofold. The first objective was to quantify and compare the spirometric measures of lung function in smokers and nonsmokers having similar demographic and lifestyle characteristics. The second objective was to define the correlation between these spirometric measurements and hematologic markers of inflammation (white blood cells, monocytes, basophils, PGE1, IgG, and IgE). Systemic blood samples and spirometric measurements were obtained from 61 age-matched (33 +/- 9 years) healthy, asymptomatic smokers and nonsmokers, with similar self reported lifestyles (i.e., food, alcohol, vitamin consumption and exercise). Both male and female smokers self reported a higher coffee consumption (P < 0.05) compared to nonsmokers. Male smokers self-reported a trend toward current blue-collar versus white-collar occupation when compared with the nonsmokers. Body weight (77.6 +/- 16.6 kg) did not differ between the smokers and nonsmokers. The male nonsmokers were taller than the male smokers (P < 0.05). All subjects were asymptomatic and had clinically normal spirometry. Compared to male nonsmokers, the male smokers had lower FEF25-75% and FEF75-45% values (P < 0.05). No additional spirometric measurements, including FEV1/FVC, FEV1 and FVC were significantly different. The female smokers did not differ from the female nonsmokers (P < 0.05) in any of the spirometric endpoints measured. Thirteen statistically significant (P < 0.05) correlations involving inflammatory (white blood cells, monocytes, basophils, and PGE1) or immunologic endpoints (IgE) and spirometric measurements were observed in female smokers, female nonsmokers and male nonsmokers. No statistically significant correlations involving immunologic or inflammatory endpoints were observed in the male smokers. A better mechanistic understanding of the observed relationship between elevated hematologic inflammatory endpoints and reduced lung function may provide valuable insight into the clinical significance of these correlations.

Abstract
OBJECTIVES To determine the frequency of referral of patients age 69 years and older to the pulmonary function laboratory at a tertiary-care hospital for airflow limitation studies; to determine the point prevalence of a significant reversible component in patients with COPD as an age-related function; and to determine the proportion of patients who were prescribed bronchodilators following a pulmonary function test (PFT) demonstrating significant reversibility. DESIGN A retrospective review of pulmonary function tests of patients 69 years and older within calendar year 1990 was performed. Chart review of those showing significant reversibility to bronchodilators during a PFT was performed to determine level of follow-up. SETTING Referral-based pulmonary division in a tertiary-care hospital. PATIENTS Men and women 69 years and older who had interpretable PFTs at Northwestern Memorial Hospital (NMH) during the calendar year 1990 (n = 405). Patients whose PFTs were uninterpretable due to poor effort (n = 10) were excluded from the study. INTERVENTIONS No specific interventions were performed as a part of the study. Referring physicians may have requested a PFT with postbronchodilator (albuterol by nebulizer) testing and may have subsequently prescribed bronchodilators for their patients. MEASUREMENTS We studied the effect of age, gender, smoking history, and degree of airflow obstruction on changes in spirometry values and reversibility status after bronchodilator (if applicable) as determined by a PFT. MAIN RESULTS Of the 405 consecutive elderly patients studied, 193 (47.7%) received bronchodilators and 60 (31.1%) of these patients had significant improvement as judged by the criteria listed in the Methods section. The improvement occurred equally across all age groups (p > 0.05) and the percent responding to bronchodilators increased as the degree of obstruction increased (p < 0.001). Those who had never smoked were twice as likely to respond than were current or former smokers; men were more likely to respond than women. Most patients (84%) who responded were subsequently prescribed bronchodilators. CONCLUSIONS Responses to inhaled bronchodilators occur at all ages. Older patients showed greater reversibility as the degree of obstruction increased, while a smoking history reduced the likelihood of a bronchodilator response. COPD in the elderly may differ from the traditional form of the disease.

Abstract
The etiology, clinical presentation, and mortality of acute upper gastrointestinal bleeding in patients with chronic obstructive pulmonary disease (COPD) were analyzed in a case-controlled study of 53 consecutive patients admitted from 1985 through 1990 to a university teaching hospital. The primary controls were 40 consecutive patients with acute upper gastrointestinal bleeding and without COPD admitted from June through November 1990 to the same hospital. COPD patients had a significantly increased mortality from gastrointestinal bleeding as compared to controls with gastrointestinal bleeding and without COPD (mortality in COPD = 32%, controls = 10%, odds ratio = 4.3, confidence interval of odds ratio = 1.22-14.8, P < 0.01, Fisher's exact test) and as compared to a second control group of 53 consecutive COPD patients without gastrointestinal bleeding (mortality in second controls = 11%, odds ratio = 3.7, confidence interval of odds ratio = 1.25-11.0, P < 0.02, chi square). The study COPD patients had a significantly greater likelihood of being older, smokers, alcoholics, and taking corticosteroids than the primary controls. However, an increased mortality was still present when controlling for these differences by population stratification (eg, mortality in patients > or = 60 years old: COPD = 36%, controls = 13%, odds ratio = 4.6, P < 0.05). The two groups had similar mean values of parameters of bleeding severity, such as lowest hematocrit and units of packed erythrocytes transfused. The increased mortality was correlated with COPD severity (eg, four of five patients with prior endotracheal intubation for COPD died, 13 of 48 COPD patients without prior intubation died, odds ratio = 10, P < 0.04, Fisher's exact test).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
BACKGROUND In clinical investigations elastin peptide concentration has been proposed as one potential marker of lung elastin degradation. No epidemiological study has yet confirmed this hypothesis. METHODS The relation of elastin peptide concentration to some factors closely related to pulmonary emphysema (age, smoking habits, FEV1 alpha protease inhibitor (PI) phenotype) and to alcohol consumption was examined in an epidemiological study of 310 working men. The elastin peptides used for obtaining antibodies and as reference in an ELISA assay were prepared from chemically hydrolysed elastin. RESULTS The elastin peptide concentration significantly decreased with age from 2.92 (1.54) micrograms/ml among subjects younger than 30 years to 2.18 (1.14) micrograms/ml among subjects older than 50. Elastin peptide concentration did not differ with smoking habits and was clearly unrelated to FEV1. A lower elastin peptide concentration was observed in all groups of subjects with a protease inhibitor phenotype other than PI MM (PI FM, IM, MP, MS, MZ, and S phenotypes). CONCLUSIONS The results cast doubts on the usefulness of the elastin peptide concentration as a marker of lung destruction in middle aged, predominantly healthy men. Blood elastin peptide concentration may reflect both elastin degradation and resynthesis. The results of this analysis suggest that several factors (age, alcohol consumption, non-PI MM phenotype) may be associated with decreased resynthesis of lung elastin. Further studies, conducted in various age groups and including estimates of the degree of lung destruction, are needed to unravel the mechanisms underlying lysis and resynthesis of lung elastin.
