The Interest in Betting, Smoking, Alcohol, and Drugs in Malawi: Changing Trends between 2012-2022.

Background: In recent years, the online gambling market has rapidly developed, and betting has become one of the most popular forms of gambling. The aim of this study was to analyse the interest of the Malawian population in terms related to betting, sports betting, alcohol, cigarettes, and some psychoactive drugs through the relative search volumes of Google Trends. Methods: Internet search query data related to betting, sports betting, alcohol, cigarettes, and psychoactive drugs were obtained monthly from Google Trends for the period 2010-2022. Comparisons of interest levels in these topics were conducted in Malawi, and correlation coefficients were calculated. Results: In Malawi, relative search volumes for betting and sports betting terms were the highest (average RSVs: 66% and 30%). It was found that from 2019 onwards, the interest in betting and sports-related search topics and keywords increased significantly (p < 0.001). Strong positive correlations were found between betting-related keywords and alcohol and gross domestic product (r = 0.831 and r = 0.901, p < 0.001). A positive correlation was found between betting and psychoactive drug-related terms (minimum r = 0.417, p < 0.01). Conclusions: This study concludes that the interest of the Malawian population in betting has increased in recent years, while interest in psychoactive drugs and alcohol remains high. Gross domestic product is highly correlated with society's interest in betting. It was additionally found that Google Trends can be used as a tool to predict and monitor future risky behaviours, such as gambling disorder.

Trends in child and adolescent assault and maltreatment following the re-introduction of the Banned Drinker Register in the Northern Territory, Australia.

OBJECTIVE: In 2017 the Northern Territory (NT) government re-introduced the Banned Drinker Register (BDR) to address the high rates of alcohol related harm. This paper aims to evaluate whether trends in assault, maltreatment and sentinel injuries in children and adolescents were associated with the re-introduction of the BDR, in the context of other local interventions such as police officers stationed in bottle shops being partially removed, Police Auxiliary Liquor Inspectors, and the introduction of a minimum unit price of alcohol. METHOD: Interrupted time series analysis was used to assess monthly trends in emergency department presentations and inpatient hospital admissions for assault, maltreatment and sentinel injuries between January 2014 and December 2019 in the regions of Greater Darwin, Alice Springs, and Katherine. RESULTS: A significant step increase after the introduction of the BDR in emergency department presentations for assault and maltreatment was present when examining the three regions combined (ß = 7.65, 95 % CI = 2.15, 13.16). However, this was not present at the individual community level. Results across a range of other models pointed towards null effects of the BDR introduction. CONCLUSIONS: The current study found that the re-introduction of the BDR had minimal impact on rates of assault, maltreatment, or sentinel injuries in children and adolescents. To ensure long-term harm mitigation from alcohol use, a combination of evidence informed alcohol policies that address the price and availability of alcohol in a comprehensive framework, along with measures which address the underlying social determinants of unregulated drinking and health more broadly will assist in reducing alcohol related harm in both children and adults.

Trends in marijuana and heavy alcohol use by cigarette smoking status among US adults: An analysis of the 2002-2019 NSDUH.

BACKGROUND: Polysubstance use is associated with adverse health outcomes, yet little research has measured changes in polysubstance use. We aimed to 1) estimate trends in marijuana and heavy alcohol use by cigarette smoking and demographic subgroups, and 2) examine patient factors associated with concurrent use among adults who were smoking. METHODS: We conducted a repeated cross-sectional analysis of 687,225 non-institutionalized US adults ≥18 years from the 2002-2019 National Survey on Drug Use and Health. Participants were stratified into current, former, and never smoking groups. Main outcomes were prevalence of heavy alcohol use, marijuana use, and concurrent use of both substances. RESULTS: From 2002-2019, heavy alcohol use declined from 7.8 % to 6.4 %, marijuana use rose from 6.0 % to 11.8 %, and concurrent use of alcohol and marijuana remained stable. Among adults who were smoking from 2005 to 2019, higher education was associated with higher odds of heavy alcohol use, while older ages, female gender, non-White race/ethnicity, and government-provided health insurance were associated with lower odds. The odds of marijuana use decreased in females, older ages, and higher incomes while increasing in people with poorer health status, higher education, government-provided or no health insurance, and serious mental illness. Compared to White adults who were smoking, Black counterparts had higher odds of marijuana use (OR=1.23; 95 %CI: 1.15-1.29), while Hispanic (OR=0.68; 95 %CI: 0.63-0.72) and other racial/ethnic identities (OR=0.83; 95 %CI: 0.77-0.90) had lower odds. CONCLUSIONS: Our study suggests marijuana use might not be sensitive to changes in the use of tobacco and alcohol.

Intimate partner violence is related to future alcohol use among a nationwide sample of LGBTQIA+ people: Results from The PRIDE Study.

BACKGROUND: Lesbian, gay, bisexual, transgender, queer, intersex, aromantic and asexual (LGBTQIA+) communities in the United States experience higher rates of alcohol use than the general population. While experiencing intimate partner violence (IPV) is thought to lead to increased alcohol use in LGBTQIA+ people, little research has investigated the temporal relationship between IPV and alcohol use in this population. METHODS: Data from two annual questionnaires of The Population Research in Identity and Disparities for Equality Study (The PRIDE Study) longitudinal cohort (n=3,783) were included. Overall IPV and three sub-types (physical, sexual, and emotional) - measured in 2021 using the extended Hurt, Insult, Threaten, Scream (E-HITS) screening tool - was examined as a predictor of Alcohol Use Disorders Identification Test (AUDIT) score in 2022 using multivariable linear regression to assess linear and quadratic associations. Models were adjusted for sociodemographic characteristics and history of alcohol use. RESULTS: One-quarter (24.7%) of respondents reported experiencing past-year IPV in 2021. The mean AUDIT score in 2022 was 3.52 (SD = 4.13). In adjusted models, both linear (B: 0.26, 95% CI: 0.14, 0.38) and quadratic (B: -0.03, 95% CI: -0.04, -0.01) terms for overall IPV were significantly associated with next-year AUDIT score. These patterns were mirrored in each IPV sub-type, were not attenuated when accounting for relationship characteristics, and were heterogeneous across gender identity groups. CONCLUSIONS: These results provide evidence of a temporal relationship between IPV and alcohol use in LGBTQIA+ communities, suggesting that efforts to prevent and mitigate IPV may help reduce alcohol use disparities in this population.

IQ in high school as a predictor of midlife alcohol drinking patterns.

AIMS: The aim of the present study was to assess the relationship between adolescent IQ and midlife alcohol use and to explore possible mediators of this relationship. METHODS: Study data were from 6300 men and women who participated in the Wisconsin Longitudinal Study of high-school students graduating in 1957. IQ scores were collected during the participants' junior year of high school. In 2004, participants reported the number of alcoholic beverages consumed (past 30 days) and the number of binge-drinking episodes. A multinomial logistic regression was conducted to determine the relationship between adolescent IQ and future drinking pattern (abstainer, moderate drinker, or heavy drinker), and Poisson regression was used to examine the number of binge-drinking episodes. Two mediators-income and education-were also explored. RESULTS: Every one-point increase in IQ score was associated with a 1.6% increase in the likelihood of reporting moderate or heavy drinking as compared to abstinence. Those with higher IQ scores also had significantly fewer binge-drinking episodes. Household income, but not education, partially mediated the relationship between IQ and drinking pattern. CONCLUSIONS: The present study suggests that higher adolescent IQ may predict a higher likelihood of moderate or heavy drinking in midlife, but fewer binge-drinking episodes. The study also suggests that this relationship is mediated by other psychosocial factors, specifically income, prompting future exploration of mediators in subsequent studies.

Seven-years of alcohol consumption in Australia by wastewater analysis: Exploring patterns by remoteness and socioeconomic factors.

BACKGROUND: Wastewater analysis provides a complementary measure of alcohol use in whole communities. We assessed absolute differences and temporal trends in alcohol consumption by degree of remoteness and socioeconomics indicators in Australia from 2016 to 2023. METHODS: Alcohol consumption estimates from 50 wastewater treatment plants (WWTP) in the Australian National Wastewater Drug Monitoring Program were used. Trends were analysed based on 1) site remoteness: Major Cities, Inner Regional and a combined remoteness category of Outer Regional and Remote, and 2) using two socioeconomic indexes from the Australian Bureau of Statistics (ABS) relating to advantage and disadvantage for Income, education, occupation, and housing. RESULTS: Consumption estimates were similar for Major Cities and Inner Regional areas (14.3 and 14.4L/day/1000 people), but significantly higher in Outer Regional and Remote sites (18.6L/day/1000 people). Consumption was decreasing in Major cities by 4.5% annually, Inner Regional by 2.4%, and 3.5% in the combined Outer Regional and Remote category. Consumption estimates were higher in socioeconomically advantaged quartiles than those of lower advantage (0%-25% mean = 13.0, 75%-100% mean = 17.4). Consumption in all quartiles decreased significantly over the 7 year period with annual rates of decrease of 0.9%, 3.7%, 3.6%, and 3.0% for the lowest to highest quartile, respectively. CONCLUSIONS: Declines in Australian alcohol consumption have been steeper in large urban areas than regional and remote areas. There were smaller annual decreases in the most socioeconomically disadvantaged areas. If continued, these trends may increase Australian health inequalities. Policy and prevention work should be appropriately targeted to produce more equitable long-term outcomes.

Changes in self-reported cannabis use in the United States from 1979 to 2022.

BACKGROUND AND AIMS: Multiple countries are considering revising cannabis policies. This study aimed to measure long-term trends in cannabis use in the United States and compare them with alcohol use. DESIGN AND SETTING: Secondary analysis of United States general population survey data. PARTICIPANTS: The national surveys had a total of 1 641 041 participants across 27 surveys from 1979 to 2022. MEASUREMENTS: Rates of use reported to the US National Survey on Drug Use and Health and its predecessors are described, as are trends in days of use reported. Four milepost years are contrasted: 1979 (first available data and end of relatively liberal policies of the 1970s), 1992 (end of 12 years of conservative Reagan-Bush era policies), 2008 (last year before the Justice Department signaled explicit federal non-interference with state-level legalizations) and 2022 (most recent data available). FINDINGS: Reported cannabis use declined to a nadir in 1992, with partial recovery through 2008, and substantial increases since then, particularly for measures of more intensive use. Between 2008 and 2022, the per capita rate of reporting past-year use increased by 120%, and days of use reported per capita increased by 218% (in absolute terms from the annual equivalent of 2.3 to 8.1 billion days per year). From 1992 to 2022, there was a 15-fold increase in the per capita rate of reporting daily or near daily use. Whereas the 1992 survey recorded 10 times as many daily or near daily alcohol as cannabis users (8.9 vs. 0.9 M), the 2022 survey, for the first time, recorded more daily and near daily users of cannabis than alcohol (17.7 vs. 14.7 M). Far more people drink, but high-frequency drinking is less common. In 2022, the median drinker reported drinking on 4-5 days in the past month, versus 15-16 days in the past month for cannabis. In 2022, past-month cannabis consumers were almost four times as likely to report daily or near daily use (42.3% vs. 10.9%) and 7.4 times more likely to report daily use (28.2% vs. 3.8%). CONCLUSIONS: Long-term trends in cannabis use in the United States parallel corresponding changes in cannabis policy, with declines during periods of greater restriction and growth during periods of policy liberalization. A growing share of cannabis consumers report daily or near daily use, and their numbers now exceed the number of daily and near daily drinkers.

Trends in purchasing cross-border, illicit and home-brewed alcohol: A population study in Great Britain, 2020-2023.

INTRODUCTION: The last 3 years have seen substantial changes in Great Britain (GB) including the COVID-19 pandemic, cost-of-living crisis and policy changes such as minimum unit pricing. We examined changes in purchasing cross-border, illicit and home-brewed alcohol among risky drinkers over this period. METHODS: Data were used from 22,086 adult (≥18 years) increasing/higher-risk drinkers (AUDIT-C ≥5) participating in a monthly cross-sectional survey between October 2020 and August 2023. We estimated time trends in the proportion reporting obtaining alcohol from: (i) cross-border (any/within-GB/international); (ii) illicit; and (iii) home-brewed sources in the past 6 months. RESULTS: Between October 2020 and August 2023, the proportion reporting cross-border alcohol purchases increased (from 8.5% to 12.5% overall; prevalence ratio [PR] = 1.47 [95% CI 1.17-1.86]). This was largely driven by an increase in cross-border purchases abroad (PR = 1.52 [1.13-2.05]), with a smaller, uncertain increase in cross-border purchases within GB (PR = 1.37 [0.96-1.95]). The prevalence of cross-border alcohol purchasing was higher in Wales (13.8% [12.3-15.4%]) and Scotland (6.1% [5.4-6.8%]) than England (3.6% [3.3-3.9%]). There was little change in illicit alcohol purchasing in England or Wales (4.1% [3.7-4.4%]; 4.2% [3.2-5.1%]), but in Scotland it fell from 5.7% to 2.4% (PR = 0.42 [0.19-0.81]). Home-brewed alcohol was rare (GB: 3.1% [2.9-3.4]) and stable. DISCUSSION AND CONCLUSIONS: The proportion of increasing/higher-risk drinkers in GB purchasing cross-border alcohol increased between October 2020 and August 2023, due to an increase in people buying alcohol abroad. Cross-border alcohol purchases within GB were more commonly reported in Wales and Scotland. The small proportion purchasing illicit alcohol did not change substantially in England or Wales, but fell by half in Scotland.

Characteristics, toxicology and major organ pathology of deaths due to acute alcohol toxicity in Australia, 2011-2022.

INTRODUCTION: Acute alcohol toxicity is a significant component of alcohol-related mortality. The study aimed to: (i) determine the circumstances of death and characteristics of fatal alcohol toxicity cases, 2011-2022; (ii) determine their toxicological profile and major autopsy findings; and (iii) determine trends in population mortality rates. METHODS: Retrospective study of acute alcohol toxicity deaths in Australia, 2011-2022, retrieved from the National Coronial Information System. RESULTS: A total of 891 cases were identified, with a mean age of 49.2 years, 71.0% being male. Alcohol use problems were noted in 71.3%. In 57.5% death was attributed solely to acute alcohol toxicity, and combined acute alcohol toxicity/disease in 42.5%. There was evidence of sudden collapse in 24.9% of cases. The mean BAC was 0.331 g/100 mL (range 0.107-0.936), and spirits were the most commonly reported beverages (35.8%). Cases of combined toxicity/disease had significantly lower BACs than those attributed solely to alcohol toxicity (0.296 vs. 0.358 g/100 mL). Cardiomegaly was diagnosed in 32.5%, and severe coronary artery disease in 22.1%. Aspiration of vomitus was noted in 18.0%, and chronic obstructive pulmonary disease in 19.6%. Severe liver steatosis was present in 33.4% and 13.6% had cirrhosis. There was an average annual percentage increase in deaths of 7.90. DISCUSSION AND CONCLUSIONS: The 'typical' case was a long-standing, heavy spirits drinker. BACs showed enormous variation and no arbitrary concentration may be deemed lethal. Clinically significant disease was associated with death at a lower BAC and people with such disease may be at increased risk of alcohol poisoning.

Alcohol and Substance Use Among the Working Age Population: A Nationwide Study of Fall-Related Emergency Department Visits.

OBJECTIVE: Prior studies have linked fall-related emergency department (ED) visits among older adults to alcohol use. Characteristics related to falls in the working age population (WAP; 15-64 years) may vary with alcohol and substance use. This study aimed to identify factors associated with fall-related ED visits related to alcohol and substance use in the WAP. METHOD: Using nationally representative 2019-2020 National Hospital Ambulatory Medical Care Survey data, fall-related ED visits within 72 hours were stratified by indication of alcohol use, substance use, and concurrent alcohol and substance use. Descriptive statistics accounting for the survey's complex design were used along with multivariable logistic regression to identify associated factors. RESULTS: Between 2019 and 2020, an estimated 10,800,000 fall-related ED visits occurred among the WAP, with 51.7% related to alcohol use, substance use, or both. Multivariable logistic regression analysis revealed that the WAP with fall-injury ED visits were associated with alcohol use (adjusted odds ratio [AOR] = 2.3, 95% CI [1.0, 5.9]) or concurrent alcohol and substance use (AOR = 8.5, 95% CI [1.6, 43.0]), and individuals with alcohol and substance use with a depression diagnosis are twice as likely to visit EDs with fall injuries. CONCLUSIONS: Individuals with alcohol and substance use with depression were twice as likely to visit EDs for fall injuries. Higher fall-related ED visits in the WAP were attributed to alcohol and substance use. Identified factors could improve injury prevention and timely intervention among the WAP in the United States.

Evolving Disparities in Cannabis Use Among Youth by Demographics and Tobacco and Alcohol Use in the U.S.: 2013-2021.

INTRODUCTION: This study investigated the prevalence of past 30-day cannabis use among U.S. youth by cigarette use, alcohol use, demographics, and state-of-residence cannabis legal status in 2021 and examined whether changes in cannabis use prevalence were modified by these factors from 2013 to 2021. METHODS: Data were drawn from the 24 states that collected cannabis use data participating in the Youth Risk Behavior Surveillance System from 2013 to 2021. Logistic regression analyses estimated past 30-day cannabis prevalence in 2021 and produced AORs by current cigarette, alcohol, and state-of-residence cannabis legal status. The same method was used with year as the exposure, adjusting for sex, race, and ethnicity, to assess trends in prevalence from 2013 to 2021. RESULTS: In 2021, cannabis use was more common among female youth (16.75% vs 13.83% [AOR=1.26, 95% CI=1.16, 1.37]) and non-Hispanic Black and Hispanic youth than among non-Hispanic White youth (17.19%, 16.14% vs 14.60% [AOR=1.25, 95% CI=1.12, 1.39 and AOR=1.16, 95% CI=1.04, 1.29, respectively]). Cannabis use was much more common among youth who reported any past 30-day cigarette or alcohol use (44.90% vs 6.48% [AOR=11.80, 95% CI=10.57, 13.18]). Declines in cannabis use were observed independent of state-level cannabis law from 2013 to 2021, and cannabis use prevalence did not differ significantly by state-of-residence cannabis legal status among the 24 participating states in 2021. CONCLUSIONS: Public health officials should carefully consider the potential impact of expanding commercialization of cannabis as a wellness product on youth cannabis use, especially with regard to minoritized populations and co-use with tobacco and alcohol. National and state-level public health education on cannabis use and youth-oriented prevention of cannabis uptake are long overdue.

Canada's Alcohol Deficit, 2007-2020: Social Cost, Public Revenue, Magnitudes of Alcohol Use, and the Per-Drink Net Deficit for a Fourteen-Year Period.

OBJECTIVE: Governments generate substantial revenue from the distribution and sale of alcoholic beverages. However, the use of this alcohol results in considerable public costs for health care, criminal justice, and economic loss of production. Because comparisons of these two sides of the same coin are limited, this study aims to estimate this net alcohol surplus or deficit in Canada and each province/territory for a 14-year study period. METHOD: Net government revenue from alcohol sales and net social costs of alcohol use were estimated for Canada and each province/territory for all years of study from 2007 to 2020, and all dollar figures were Consumer Price Index-adjusted to 2020 Canadian dollars (CAD). The net alcohol surplus/deficit was estimated as the difference. Per capita recorded alcohol sold was from administrative sources and used as proxy to calculate alcohol used by adding an estimate of unrecorded use and converting to Canadian standard drinks (CSDs). The per-drink net deficit was the net deficit divided by CSDs. RESULTS: In Canada in 2020, governments generated CAD $13.3 billion in revenue from alcohol sales, but this was offset by $19.7 billion in social costs attributable to alcohol use. This "alcohol deficit" increased by 122.0% in real-dollar terms over the study period and reached a high of $6.4 billion in 2020. In 2020, the magnitude of the alcohol used in Canada was 16.8 billion CSDs. Each of these drinks resulted in a public net deficit of $0.379. CONCLUSIONS: Both alcohol use and the resulting public alcohol deficit are high in Canada. To mitigate these losses to the well-being of Canadians and their economy, government planners, regulators, and policymakers must urgently deploy evidence-based alcohol policies toward reducing the magnitude of alcohol used in Canada.

The COVID-19 alcohol paradox: British household purchases during 2020 compared with 2015-2019.

British supermarket-panel data suggest no increases in overall sales and purchases of alcohol following COVID-19 lockdowns, yet survey and mortality data suggest otherwise. This paper attempts to unravel the paradox. Based on purchase data of 79,417 British households from Kantar Worldpanel, we undertake controlled interrupted time series analysis of the impact of COVID-19 confinement introduced on 23rd March 2020, and variably applied during 2020, compared to purchases during 2015 to 2019 as controls. We also undertook Poisson regression analyses to estimate if changes in purchases differed by household socio-demographic and economic factors. Excess off-trade household alcohol purchases (expressed as grams of ethanol) following the introduction of confinement, were 29.2% higher (95% CI = 25.8% to 32.5%) for the post-confinement months of 2020, being larger until mid-July 2020 (37.5%, 95%CI = 33.9 to 41.26%) when pubs re-opened with restrictions, and smaller (24.6%, 95%CI = 21.6 to 27.7) thereafter. During the time of complete pub closures, and fully adjusting for no on-trade purchases, household purchases of alcohol did not change when compared with the same time period during 2015-2019 (coefficient = -0.9%, 95%CI = -5.6 to 3.8). Excess purchases from 23rd March to 31st December 2020 varied by region of Great Britain, being higher in the north of England, and lower in Scotland and Wales. Excess purchases were greater in the most deprived households, compared with the least deprived households. Excess purchases increased substantially as the amount of alcohol normally purchased by a household increased, with the top one fifth of households that normally bought the most alcohol increasing their purchases more than 17 times than the bottom one fifth of households that bought the least alcohol. That the heaviest buyers of alcohol increased their purchases the most, with some independent impact of socio-economic disadvantage, might explain why reported alcohol problems and recent alcohol-related death rates might have increased. A conclusion of this is that alcohol policy to reduce high consumption of alcohol, and the availability of help and treatment to reduce alcohol consumption become more important during extraordinary times, such as COVID lockdowns.

A machine learning-based biological aging prediction and its associations with healthy lifestyles: the Dongfeng-Tongji cohort.

This study aims to establish a biological age (BA) predictor and to investigate the roles of lifestyles on biological aging. The 14,848 participants with the available information of multisystem measurements from the Dongfeng-Tongji cohort were used to estimate BA. We developed a composite BA predictor showing a high correlation with chronological age (CA) (r = 0.82) by using an extreme gradient boosting (XGBoost) algorithm. The average frequency hearing threshold, forced expiratory volume in 1 second (FEV1 ), gender, systolic blood pressure, and homocysteine ranked as the top five important features for the BA predictor. Two aging indexes, recorded as the AgingAccel (the residual from regressing predicted age on CA) and aging rate (the ratio of predicted age to CA), showed positive associations with the risks of all-cause (HR (95% CI) = 1.12 (1.10-1.14) and 1.08 (1.07-1.10), respectively) and cause-specific (HRs ranged from 1.06 to ∼1.15) mortality. Each 1-point increase in healthy lifestyle score (including normal body mass index, never smoking, moderate alcohol drinking, physically active, and sleep 7-9 h/night) was associated with a 0.21-year decrease in the AgingAccel (95% CI: -0.27 to -0.15) and a 0.4% decrease in the aging rate (95% CI: -0.5% to -0.3%). This study developed a machine learning-based BA predictor in a prospective Chinese cohort. Adherence to healthy lifestyles showed associations with delayed biological aging, which highlights potential preventive interventions.

Trends in psychiatric hospitalization for alcohol and drugs in Castilla y León between 2005 and 2015. / Tendencias en la hospitalización psiquiátrica por alcohol y drogas en Castilla y León entre 2005 y 2015.

It has been estimated that alcohol, tobacco, and illicit drugs were responsible for more than 10 million deaths worldwide in 2016, and there are many opportunities for improvement. Regarding innovative data analysis, advances have been made in the extraction of information from administrative databases for analytics purposes. We studied trends in hospitalization rates for alcohol and drug abuse over eleven years with Joinpoint Trend Analysis software. This is a descriptive study of cross-associations in 3,758 hospital admissions of patients admitted with a main diagnosis of alcohol and drug abuse or dependence in psychiatry units of public health centres of Castilla y León (Spain) between 2005 and 2015. Hospitalization trends for alcohol and drug related conditions declined over the eleven-year period. Separately, there was a statistically significant decrease in alcohol and cocaine related conditions, but a strong upward trend in cannabis related conditions between 2013 and 2015. Alcohol was the main cause of admission to psychiatric units with a diagnosis of addiction. In the 11 years researched, there was a progressive and constant reduction in admissions for substance use except for cannabis. The innovative statistical methodology has already proven to be useful for identifying trends and changes in different pathologies over time.

A nivel mundial, se ha estimado que el alcohol, el tabaco y las drogas han sido responsables de más de 10 millones de muertes en 2016, y que existe mucho margen para reducir la mortalidad. Se han realizado avances en la extracción de información de bases de datos administrativas con el fin de analizar grandes volúmenes de datos sanitarios. Hemos estudiado las tendencias en las tasas de hospitalización con diagnóstico de adicción a alcohol y drogas durante once años con el software Joinpoint Trend Analysis. Se trata de un estudio descriptivo de asociación cruzada de 3.758 ingresos hospitalarios de pacientes con diagnóstico principal de abuso o dependencia de alcohol y drogas en unidades de Psiquiatría de centros públicos de Castilla y León entre 2005 y 2015. Las tendencias en la hospitalización por adicción al alcohol y/o drogas disminuyeron a lo largo de los once años. Además de una reducción estadísticamente significativa de los ingresos por alcohol y cocaína, se apreció una fuerte tendencia al alza en los ingresos por cannabis entre 2013 y 2015. El alcohol fue durante todo el periodo de estudio la principal causa de ingreso y el que más días de hospitalización ha generado. No obstante, en los 11 años se observó una reducción progresiva y constante en los ingresos por todas las sustancias a excepción del cannabis. La metodología utilizada ya ha demostrado ser muy útil para identificar cambios de tendencias en diferentes patologías.

Novel genomic alteration in superficial esophageal squamous cell neoplasms in non-smoker non-drinker females.

Alcohol consumption and smoking pose a significant risk for esophageal squamous cell neoplasia (ESCN) development in males; however, ESCN is often diagnosed in non-drinking and non-smoking females. The mechanisms underlying these differences remain elusive, and understanding them can potentially identify novel pathways involved in ESCN development. We performed short-read sequencing to identify somatic variants on a cancer panel targeting 409 genes using DNA extracted from the superficial squamous cell carcinoma (ESCC) tissues and adjacent non-neoplastic epithelium (NE), and immunohistochemical staining of the protein encoded by the target gene. All male patients (n = 117) were drinkers or smokers, whereas 45% of the female patients (n = 33) were not. Somatic variants were compared among three age-matched groups: 13 female ESCC patients with smoking and drinking habits (known-risk group, F-KR), 13 female ESCC patients without these habits (unknown-risk group, F-UR), and 27 males with ESCC and smoking and drinking habits (M-KR). In the NE, the frequencies of CDKN2A variants were significantly higher in F-UR than in F-KR and M-KR. In both ESCC and NE, p14ARF was significantly overexpressed in F-UR than in the other groups. In conclusion, CDKN2A might be important in ESCC development, independent of known risk factors.

IL-6 and IL-1ß upregulation and tau protein phosphorylation in response to chronic alcohol exposure in the mouse hippocampus.

Alcoholism and alcohol abuse can lead to memory loss and cognitive dysfunction. The neuroinflammatory response plays an important role in the neurotoxic mechanism of chronic alcohol exposure. Additionally, the phosphorylation status of the tau protein is closely related to neurotoxicity and synaptic function. As inflammatory cytokines have been shown to regulate tau phosphorylation, in the present study, the aim was to determine whether cognitive impairment caused by chronic alcohol exposure is associated with neuroinflammation and tau hyperphosphorylation in the hippocampus. We established a chronic alcohol exposure model of C57BL/6J mice. The Y maze was used to assess the spatial recognition ability of mice, and ELISA was used to detect the levels of inflammatory cytokines IL-1ß and IL-6 in the serum. Immunohistochemical and western blot assays were used to assess the expression levels of IL-1ß and IL-6, as well as tau protein and its phosphorylation status in the hippocampus. We also analyzed the mRNA and protein expression of the synapse-associated proteins PSD95 and synaptophysin in the hippocampus. Our results showed that chronic alcohol exposure impaired the spatial recognition ability of mice upregulated the expression of IL-1ß and IL-6 in the serum and hippocampus and increased the phosphorylation of tau protein in the hippocampus. In addition, chronic alcohol exposure downregulated PSD95 and synaptophysin protein levels. The present results indicate that hippocampal IL-1ß, IL-6, and phosphorylated tau proteins may be involved in the neurotoxic mechanism of chronic alcohol exposure by mediating synaptic dysfunction.
