Alcohol Use and Gastrointestinal Cancer Risk

Association between Alcohol Use Disorder and Suicidal Ideation Using Propensity Score Matching in Chungcheongnam-do, South Korea

Objectives: This study aimed to analyze the association between alcohol use disorder (AUD) and suicidal ideation (SI) in the general Korean population. Methods: The 2022 Mental Health Awareness Survey was collected from the Chungcheongnam-do Mental Health Welfare Center (CHMHC). Before Propensity Score Matching (PSM), 823 participants were included in this study. After 1:4 PSM, the 255 participants were analyzed using the chi-square test and matched conditional logistic regression. Results: The AUD group had higher odds of experiencing SI than the non-AUD (adjusted odds ratio [AOR]: 2.40, 95% confidence intervals [CI]: 1.10-5.22). Stratified matched conditional logistic regression showed that, among the female, <40 years and single group, the AUD group was more likely to experience SI compared with the non-AUD, respectively (AOR:3.53, 95% CI: 1.20-10.44/AOR:3.45, 95% CI: 1.03-11.55/AOR:4.83, 95% CI: 1.18-19.69). However, among the male, ≥40 years and married group, we discovered no association between AUD and SI. Conclusions: Through this study, we found a strong association between the AUD group and SI. This association was particularly strong among female, <40 years, and single groups. This study elucidates the relationship between AUD and SI in the Chungnam region, which had not been previously identified in Korea, and it is expected to serve as foundational data for reducing the high suicide rate in this region. However, due to the limitation of being a cross-sectional study, future longitudinal research is required.

Alcohol - a scoping review for Nordic Nutrition Recommendations 2023

The objective of this scoping review is to evaluate the updated evidence on the consumption of alcohol and health outcomes regarded as relevant for the Nordic and Baltic countries, including cardiovascular disease, cancer, and all-cause mortality. It is based on the previous Nordic Nutrition Recommendations of 2012 and relevant papers published until 31 May 2021. Current evidence from mainly observational epidemiological studies suggests that regular, moderate alcohol consumption may confer protective effects against myocardial infarction (MI) and type 2 diabetes. Mendelian randomization analyses do not fully support these findings, possibly because these analyses may fail to identify low alcohol intake. For several cancers, it is not possible to set any safe limit. All-cause mortality is not increased with light to moderate alcohol intake in middle-aged and older adults who do not engage in binge drinking. Total abstinence is associated with the lowest risk of mortality in young adults. Observational studies on alcohol consumption are hampered by a number of inherent methodological issues such as ascertainment of alcohol intake, selection of appropriate exposure groups, and insufficient control of confounding variables, colliders, and mediators. It should also be emphasized that there is a socio-economic contribution to the alcohol-health axis with a stronger detrimental effect of alcohol in the lower social classes. The above issues contribute to the complexity of unravelling the causal web between alcohol, mediators, confounders, and health outcome.

Extrahepatic Health Effects of Alcohol Use and Alcohol-associated Liver Disease

PURPOSE

Alcohol use disorder (AUD) is a growing public health concern and an important contributor to global morbidity and mortality. While the hepatotoxic effects of alcohol are well known, the adverse effects of alcohol are manifested in almost every organ system. With the growing public health impact of AUD, the aim of this narrative review is to highlight the epidemiology and burden of AUD and its association with extrahepatic diseases including malignancy and disorders of the gastrointestinal (GI), cardiovascular, immunologic, neurologic, endocrine, and hematologic systems.

METHODS

A narrative review of the literature was performed to identify studies addressing the epidemiology, pathophysiology, clinical manifestations, and therapy of extrahepatic health manifestations of alcohol use.

FINDINGS

In the United States, an estimated 14.5 million people have AUD and approximately 88,000 adults die yearly due to alcohol-related causes. The consumption of alcohol and AUD is associated with injuries, violence, cancers, nonmalignant conditions of the GI system, infections, effects on the cardiovascular system, and neurodegenerative diseases. These conditions contribute to the increased mortality associated with AUD and are burdensome to patients and caregivers.

IMPLICATIONS

Increased awareness of the extrahepatic manifestations of AUD, screening for AUD using validated screening tools, such as the Alcohol Use Disorders Identification Test-Concise (AUDIT-C) score, and offering evidence-based interventions to patients with AUD is imperative to reduce the public health burden of AUD. Although historically controversial, recent evidence suggests that any level of alcohol consumption can have negative health consequences. Further research is warranted to determine if any amount of alcohol is safe for consumption. Public health efforts are warranted to help curtail the growing burden of AUD.

Systemic Diseases and Gastrointestinal Cancer Risk

Importance

Gastrointestinal (GI) cancers are the second leading cause of cancer-related deaths worldwide.

Observations

The global challenges GI cancers pose are high, especially in middle- and low-income countries. Patients with these cancers present with symptoms of poor appetite, weight loss, heartburn, abdominal pain, fatigue and anaemia. Several risk factors contribute to GI cancers, including age, gender, obesity, pathogenic infections, smoking cigarettes, alcohol consumption and dietary habits. Most of these cancers are sporadic. However, some patients are at high risk due to a family history of GI cancers. Systemic diseases affect multiple organs, and their chronic occurrence elicits inflammatory responses at various sites. These diseases also contribute to GI cancers.

Conclusion and Relevance

In this review, we discuss that untreated systemic diseases, including diabetes, hepatitis, acquired immune deficiency syndrome, ulcers and hypertension, can potentially lead to GI cancers if they remain untreated for a longer period. Systemic diseases initiate oxidative stress, inflammatory pathways and genetic manipulations, which altogether confer risks to GI cancers. Here, we describe the association between systemic diseases and their underlying mechanisms leading to GI cancers.

The Promotion of Premium Cigars on Social Media

INTRODUCTION

The health effect of premium cigar smoking is determined by patterns of use and perceptions, which are shaped by marketing messages. The tobacco industry uses brand-owned media promotion on social media to market its product. However, premium cigar brands' promotion of their products on social media is unknown.

AIMS AND METHODS

Forty-seven premium cigar brands were reviewed. For each brand, we identified the social media accounts and examined the content of the 10 most recent posts of each social media platform to identify the marketing themes in July 2022. We also assessed the presence of age-gating and the dates of the posts.

RESULTS

Of the 47 brands, 65% (n = 31) had Facebook and Instagram, 56% (n = 27) had Twitter, 21% (n = 10) had YouTube, and 17% (n = 8) had "other" (e.g. LinkedIn and Pinterest) accounts. Age-gating across these platforms ranged from 0% to 49%. Marketing themes identified from 981 social media posts included product features, alcohol, holidays, events and festivals, discounts and sweepstakes, taste, family, quality, lounges and clubs, culture, innovation, masculinity, and "other" (e.g. fundraising for charity and celebrity endorsement).

CONCLUSIONS

Premium cigar brands are using brand-owned social media to promote their products using similar strategies (e.g. discounts and sweepstakes) used by other tobacco industries but also using novel themes (e.g. fundraising for charity, events and festivals) to enhance engagement. Ongoing comprehensive surveillance of premium cigars' marketing is needed on social media to inform marketing restrictions to protect public health, including priority populations such as youth.

IMPLICATIONS

This study is the first to identify that premium cigar brands are promoting their brands and products on brand-owned social media, using diverse themes and strategies to engage and appeal to the public. Age gating of the promotional content on social media was low. Findings suggest that marketing restrictions to reduce the appeal of premium cigars among youth is needed to reduce tobacco-related harm.

A model for irritable bowel syndrome and anxiety comorbidities in relation to alcohol use disorders

About 95% of human body serotonin synthesis occurs in the gastrointestinal tract (GI). Lack of sufficient serotonin levels is thought to play a key role in mood disorders, including anxiety disorders. In this study, we looked at a disorder affecting the GI tract, irritable bowel syndrome (IBS), and aimed to determine whether IBS is differentially associated with anxiety disorders in 252 chronic pain patients in the presence of a history of alcohol use disorders (AUD) given that alcohol is an extremely aggressive substance for the GI mucosa. We found that while the prevalence of IBS was not affected by the presence of AUD in chronic pain patients, IBS had significantly higher comorbidity with anxiety disorders in chronic pain patients with comorbid alcohol use disorders. We argue that these findings highlight mechanistic differences in the comorbidity of anxiety disorders with chronic pain and AUD, implicating a central role for GI problems stemming from chronic alcohol use. The findings may have important implications for the treatment of IBS patients with AUD who commonly present with anxiety disorders which could motivate the continuation of problematic drinking and impede recovery success. We propose that addressing GI problems in patients with AUD may help manage AUD and recovery more effectively.

Updated Epidemiology of Gastric Cancer in Asia: Decreased Incidence but Still a Big Challenge

Despite the decline in incidence and mortality rates, gastric cancer (GC) is the fifth leading cause of cancer deaths worldwide. The incidence and mortality of GC are exceptionally high in Asia due to high H. pylori infection, dietary habits, smoking behaviors, and heavy alcohol consumption. In Asia, males are more susceptible to developing GC than females. Variations in H. pylori strains and prevalence rates may contribute to the differences in incidence and mortality rates across Asian countries. Large-scale H. pylori eradication was one of the effective ways to reduce GC incidences. Treatment methods and clinical trials have evolved, but the 5-year survival rate of advanced GC is still low. Efforts should be put towards large-scale screening and early diagnosis, precision medicine, and deep mechanism studies on the interplay of GC cells and microenvironments for dealing with peritoneal metastasis and prolonging patients' survival.

Sleep disturbance and gastrointestinal cancer risk: a literature review

Sleep, accounting for roughly one-third of a person's life, plays an important role in human health. Despite the close association between sleep patterns and medical diseases proven by several studies, it has been neglected in recent years. Presently, all societies are facing the most challenging health-threatening disease, cancer. Among all cancer types, gastrointestinal (GI) cancers, especially colorectal type, seem to be one of the most relevant to an individual's lifestyle; thus, they can be prevented by modifying behaviors most of the time. Previous studies have shown that disruption of the 24-h sleep-wake cycle increases the chance of colorectal cancer, which can be due to exposure to artificial light at night and some complex genetic and hormone-mediated mechanisms. There has also been some evidence showing the possible associations between other aspects of sleep such as sleep duration or some sleep disorders and GI cancer risk. This review brings some information together and presents a detailed discussion of the possible role of sleep patterns in GI malignancy initiation.

[Prevention of pancreatic cancer]

The incidence of pancreatic cancer is rising in Germany. At present pancreatic cancer is the third commonest cause of cancer death but is expected to become the second in 2030 and finally the leading cause of cancer death in 2050. Pancreatic ductal adenocarcinoma (PC) is generally diagnosed at far advanced stages and 5-year-survival has remained poor. Modifiable risk factors of PC are tobacco smoking, excess body weight, alcohol use, type 2-diabetes and the metabolic syndrome. Smoking cessation and -in case of obesity- intentional weight loss can reduce PC risk by as much as 50 %. Early detection of asymptomatic sporadic PC at stage IA - stage IA-PC now has a 5-year-survival rate of about 80 %- has become a realistic chance for people older than 50 years with new-onset diabetes.

COVID-19's impact on interest in gastrointestinal topics

There has been a disparity in familiarity regarding the public interest in gastroenterology terminologies during the COVID-19 pandemic. This study aimed to understand the outcomes of the public's view on gastrointestinal topics and their potential social effects. This study is a comparative analysis of American Google Trends gastrointestinal terminology during the COVID-19 pandemic compared to a similar time frame (March 2018-February 2020) to determine how trends in the patient-seeking behavior of gastrointestinal terminology changed throughout the pandemic. The analysis discovered a substantial decrease in search volumes of gastrointestinal topics, more significantly in the first pandemic months. Later in the pandemic, search volumes trended toward pre-pandemic years in terms of public interest. In the case of gastrointestinal procedures, endoscopy and colonoscopies, they surpassed pre-pandemic interest levels statistically (p-values of 0.01 and 0.002). The public's decreased interest in gastrointestinal topics at the beginning of the COVID-19 pandemic may have adverse effects on the healthcare maintenance of patients who could have had a positive outcome in their gastrointestinal health with proper monitoring. Although gastrointestinal internet searches increased toward pre-pandemic levels as the seasons progressed, further research is needed to determine the social impact of decreased public interest.

Upper Gastrointestinal Cancer and Liver Cirrhosis

Simple Summary

There is a higher incidence rate of upper gastrointestinal cancer in those with liver cirrhosis. The contributing factors include gastric ulcers, congestive gastropathy, zinc deficiency, alcohol drinking, tobacco use and gut microbiota. Most of the de novo malignancies that develop after liver transplantation for cirrhotic patients are upper gastrointestinal cancers. The surgical risk of upper gastrointestinal cancers in cirrhotic patients with advanced liver cirrhosis is higher.

Abstract

The extended scope of upper gastrointestinal cancer can include esophageal cancer, gastric cancer and pancreatic cancer. A higher incidence rate of gastric cancer and esophageal cancer in patients with liver cirrhosis has been reported. It is attributable to four possible causes which exist in cirrhotic patients, including a higher prevalence of gastric ulcers and congestive gastropathy, zinc deficiency, alcohol drinking and tobacco use and coexisting gut microbiota. Helicobacter pylori infection enhances the development of gastric cancer. In addition, Helicobacter pylori, Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans also contribute to the development of pancreatic cancer in cirrhotic patients. Cirrhotic patients (especially those with alcoholic liver cirrhosis) who undergo liver transplantation have a higher overall risk of developing de novo malignancies. Most de novo malignancies are upper gastrointestinal malignancies. The prognosis is usually poor. Considering the surgical risk of upper gastrointestinal cancer among those with liver cirrhosis, a radical gastrectomy with D1 or D2 lymph node dissection can be undertaken in Child class A patients. D1 lymph node dissection can be performed in Child class B patients. Endoscopic submucosal dissection for gastric cancer or esophageal cancer can be undertaken safely in selected cirrhotic patients. In Child class C patients, a radical gastrectomy is potentially fatal. Pancreatic radical surgery should be avoided in those with liver cirrhosis with Child class B or a MELD score over 15. The current review focuses on the recent reports on some factors in liver cirrhosis that contribute to the development of upper gastrointestinal cancer. Quitting alcohol drinking and tobacco use is important. How to decrease the risk of the development of gastrointestinal cancer in those with liver cirrhosis remains a challenging problem.

Reduction of Cell Proliferation by Acute C2H6O Exposure

Simple Summary

Alcoholic beverages and acetaldehyde formed during their metabolism are carcinogenic to humans. Alcohol drinking may affect bone marrow stem cell niche, suppressing physiological hematopoiesis and ultimately reducing the organism’s capacity to fight against cancer, infections, and to promote tissue regeneration. To elucidate in vivo the cellular mechanisms associated with alcohol intake toxicity, we used a mouse model in which proliferating cells produce the firefly’s light-emitting protein. In this animal, alcohol exposure transiently “turns off the light”, indicating a negative effect on cell proliferation in the bone marrow and spleen. Pharmacological treatment with substances interfering with ethanol metabolism, reducing acetaldehyde production, partially restores the physiological cell proliferation rate. Over 560 million people worldwide have increased susceptibility to acetaldehyde toxicity and 4% of cancer deaths are attributable to alcohol. Our model might provide a suitable tool to further investigate in vivo the effects of alcohol metabolism and aldehydes production on carcinogenesis.

Abstract

Endogenous acetaldehyde production from the metabolism of ingested alcohol exposes hematopoietic progenitor cells to increased genotoxic risk. To develop possible therapeutic strategies to prevent or reverse alcohol abuse effects, it would be critical to determine the temporal progression of acute ethanol toxicity on progenitor cell numbers and proliferative status. We followed the variation of the cell proliferation rate in bone marrow and spleen in response to acute ethanol intoxication in the MITO-Luc mouse, in which NF-Y-dependent cell proliferation can be assessed in vivo by non-invasive bioluminescent imaging. One week after ethanol administration, bioluminescent signals in bone marrow and spleen decreased below the level corresponding to physiological proliferation, and they progressively resumed to pre-treatment values in approximately 4 weeks. Boosting acetaldehyde catabolism by administration of an aldehyde dehydrogenase activity activator or administration of polyphenols with antioxidant activity partially restored bone marrow cells’ physiological proliferation. These results indicate that in this mouse model, bioluminescent alteration reflects the reduction of the physiological proliferation rate of bone marrow progenitor cells due to the toxic effect of aldehydes generated by alcohol oxidation. In summary, this study presents a novel view of the impact of acute alcohol intake on bone marrow cell proliferation in vivo.

A global assessment of recent trends in gastrointestinal cancer and lifestyle-associated risk factors

Background

Gastrointestinal (GI) cancers were responsible for 26.3% of cancer cases and 35.4% of deaths worldwide in 2018. This study aimed to analyze the global incidence, mortality, prevalence, and contributing risk factors of the 6 major GI cancer entities [esophageal cancer (EC), gastric cancer (GC), liver cancer (LC), pancreatic cancer (PC), colon cancer, and rectal cancer].

Methods

Using the Global Cancer Observatory and the Global Health Observatory databases, we reviewed the current GI cancer incidence, prevalence, and mortality, analyzed the association of GI cancer prevalence with national human development indices (HDIs), identified the contributing risk factors, and estimated developing age‐ and sex‐specific trends in incidence and mortality.

Results

In 2020, the trend in age‐standardized rate of incidence of GI cancers closely mirrored that of mortality, with the highest rates of LC, EC, and GC in Asia and of colorectal cancer (CRC) and PC mainly in Europe. Incidence and mortality were positively, but the mortality‐to‐incidence ratio (MIR) was inversely correlated with the national HDI levels. High MIRs in developing countries likely reflected the lack of preventive strategies and effective treatments. GI cancer prevalence was highest in Europe and was also positively correlated with HDIs and lifestyle‐associated risk factors, such as alcohol consumption, smoking, obesity, insufficient physical activity, and high blood cholesterol level, but negatively correlated with hypertension and diabetes. Incidences of EC were consistently and those of GC mostly decreasing, whereas incidences of CRC were increasing in most countries/regions, especially in the younger populations. Incidences of LC and PC were also increasing in all age‐gender populations except for younger males. Mortalities were decreasing for EC, GC, and CRC in most countries/regions, and age‐specific trends were observed in PC and LC with a decrease in the younger but an increase in the older population.

Conclusions

On the global scale, higher GI cancer burden was accompanied, for the most part, by factors associated with the so‐called Western lifestyle reflected by high and very high national HDI levels. In countries/regions with very high HDI levels, patients survived longer, and increasing GI cancer cases were observed with increasing national HDI levels. Optimizing GI cancer prevention and improving therapies, especially for patients with comorbid metabolic diseases, are thus urgently recommended.

Excess Body Weight and Gastrointestinal Cancer Risk

Background

Excess body weight (EBW), defined as a body mass index (BMI) ≥25 kg/m², has become the second most important as well as a potentially modifiable risk factor for cancer in many industrialized countries. The more excess weight people have, the higher the risk of certain cancers. Over the past several decades, EBW has been increasing globally not only among adults, but also among children and adolescents.

Summary

EBW is causally associated with colorectal, esophageal (adenocarcinoma), gastric (cardia), pancreatic, biliary and hepatocellular cancer. EBW when combined with tobacco smoking, risky alcohol use, or diabetes can act synergistically to cause gastrointestinal cancer. In recent years, more and more young adults (20-40 years old) were diagnosed with EBW-associated neoplasms. People with EBW should be encouraged to join cancer screening programs.

Key Messages

Keeping a healthy weight is a major public health concern and reduces the risk of cancer.

Secular decreasing trends in gastric cancer incidence in Taiwan: A population-based cancer registry study

BACKGROUND

Gastric cancer remains a leading cause of cancer death worldwide. In Taiwan, gastric cancer is the sixth leading cause of cancer mortality in both males and females.

AIM

To evaluate secular trends in gastric cancer incidence according to age, sex, and Helicobacter pylori (H. pylori) treatment in Taiwan.

METHODS

In this population-based study, we used the national Taiwan Cancer Registry database. Annual percent changes in incidence rates were used to describe secular trends in incidence rates and sex ratios of gastric cancer in Taiwan. Pearson’s product-moment correlation coefficients were used to analyze the correlation between annual age-adjusted incidence rates and the annual number of patients treated with antibiotic therapy for H. pylori infection.

RESULTS

The annual percent changes showed continuously decreasing rates of gastric cancer among both males and females. However, the decreasing trends differed by sex, with an annual percent change of -2.58% in males and -2.14% in females. The age-specific incidence rates increased with age. Within the same age group, more recent time periods showed lower incidence rates than greater time periods. Similarly, the sex ratio was lower in later birth cohorts than in earlier birth cohorts. Age-adjusted incidence rates substantially decreased with increasing numbers of patients being treated with antibiotic therapy for H. pylori infection during 2005 to 2016 (r = 0.72).

CONCLUSION

We observed steadily decreasing trends with differential sex ratios in the incidence of gastric cancer in Taiwan. These results support H. pylori eradication programs in Taiwan.

Dietary Diversity and Healthy Aging: A Prospective Study

Population aging is a global phenomenon. The present study determined the effects of dietary diversity score (DDS) and food consumption on healthy aging. A subset of the data of the China Health and Nutrition Survey was utilized in this study. DDSs were calculated using the dietary data collected in the years 2009 and 2011. A healthy aging score (HAS) was calculated by summing the standardized scores on physical functional limitation, comorbidity, cognitive function, and psychological stress based on the data collected in the year 2015, with a lower HAS indicating a healthier aging process. Life quality was self-reported in the year 2015. This study found that DDS was inversely associated with HAS (T3 vs. T1: β −0.16, 95%CI −0.20 to −0.11, p-trend <0.001). The consumption of meat and poultry, aquatic products, and fruits was inversely associated with HAS, and participants in the highest tertile of staple foods consumption had a higher HAS than those in the lowest tertile. HAS was inversely associated with good self-reported life quality and positively associated with bad life quality. In conclusion, food consumption may influence the aging process, and adherence to a diverse diet is associated with a healthier aging process in elderly people.
