Epidemiology and Clinical-Demographic Characteristics of Suicide Attempts in Alcohol Use Disorders in an Italian Population.

Suicide is a leading cause of morbidity worldwide. Among the known risk factors, alcohol use disorders (AUDs) are particularly relevant, but data on the epidemiology and characteristics of suicide attempts (SA) in this group are lacking. We used electronic health records of national health services to identify individuals who received a diagnosis of AUD in the Metropolitan area of Bologna from 2009 to 2019. In this cohort we identified accesses to Emergency Departments for SA from 2009 to 2020. The Crude Suicide Rate (CSR) for 1,000 Person Years was 2.93, higher than the general population. The CSR was higher in females, within one year from receiving the diagnosis of AUD, in patients with psychiatric comorbidities, concomitant abuse of cannabis or benzodiazepines. As for Covid-19 pandemic, the risk ratio of SA was significantly higher in 2020 compared to 2019 in females. Our results are relevant to identify clinical risk factors for SA in patients with AUDs, which are strongly associated with suicide risk but with scarce data in the previous literature and paucity of evidence-based therapeutic interventions.

Mortality risk in a population of patients treated for gambling disorders: results of a follow-up study.

AIMS: To examine mortality risk and causes of death in a cohort of a population of patients treated for gambling disorders in northern Italy from 1992 to 2019. METHODS: Cohort study. RESULTS: Half of the patients were diagnosed with psychiatric disorders, substance use disorder or alcohol dependence. The excess mortality compared to the general population (SMR) was 1.16 (0.85-1.58), more elevated among females aged 40 to 59 and males aged 20 to 29. Females had higher SMRs for all cancers and suicide; males for malignant neoplasm of liver, of lung, of prostate, and of bladder. CONCLUSIONS: Despite patients increasing, subjects who most turn to the services are the most serious ones, in older age, with comorbid mental disorders and with a compromised health status. This is reflected in the high risk of death for all cancers.

Mortality Risk among Cocaine Users before and after the Economic Recession: Results of a Longitudinal Study.

BACKGROUND: Studies have highlighted 2 different groups of cocaine users (CUs): "socially integrated" (stable living conditions, regular employment, use cocaine alone or in combination with other psychoactive substances) and "socially marginalized" (socioeconomic and health problems, former or current heroin users, many injecting cocaine). These differences are also found in the elevated mortality risk for CUs, higher among subjects with cocaine and heroin use. This study targeted residents in Northern Italy who turned to a public treatment center for drug addiction following problems caused by primary cocaine use between 1982 and 2016. OBJECTIVES: To estimate mortality risk for subjects who have never used heroin (CUs) compared to that of subjects who have used heroin (HCUs). METHOD: Retrospective cohort study. We selected 1,993 subjects; 18,015 Person Years (PY). RESULTS: Over time, the quota of subjects injecting cocaine and using heroin decreased, while patients not using heroin increased. Both new patients and crude mortality rates (CMR) decreased during the years 2009-2012 and increased in the following period. CMRs were 5.55 per 1,000 PY, higher for HCUs, men and subjects aged over 44 years. Standardized mortality rates were 3.49, higher for women, injecting cocaine and HCUS. Among CUs, most of the deaths were from injury excluding drug related and tumors; among HCUs, from drug-related causes and diseases of the cardiovascular system. CONCLUSION: The study results show a change in the characteristics of SERD clients being treated for primary cocaine use, which are reflected both in mortality risk and causes of death. After a long period of a decrease, mortality risk increased in the period after the economic recession. Aspects concerning the effects of the economic recession on the problematic consumption of cocaine and on the risk of death are discussed.

Mortality Risk among Heroin Users Accessing Treatment: Natives and Non-Natives Patients Results of a Longitudinal Study.

The aim of this study was to examine mortality risk and causes of death for natives and non-natives in a cohort of heroin population of treated in Northern Italy. Crude Mortality Rates (CMRs) were 12.78 per 1,000 Person Years (PY), Standardized Mortality Rate (SMR) was 9.93. Mortality has been decreasing over time, was higher for patients who accessed the treatment services before 2001 and has been increasing with age. CMRs and SMRs were higher among natives, while non-natives were distinguished by higher CMRs and SMRs for suicide. The natives were at greater risk of death than non-natives both injecting and non-injecting, but the mortality risk was not statistically significant in the different periods of first admission. Among non-native patients, older on average, there was a lower proportion of injecting, and a higher quota of people unemployed than among Italian natives. We highlight differences between the various areas of origin concerning consumption patterns and risk of death. The results of the study highlight a particular sub-population of heroin users, the non-natives, who as compared with the Italians, have less invasive consumption styles, reach the health services later but benefit from fewer medical controls.

Ketamine abusers referring to emergency departments in northern Italy: a cross- sectional study.

INTRODUCTION: Ketamine is an essential medicine used as an anesthetic in low and middle-income countries and in veterinary medicine. Recreational use is widespread throughout the world, especially owing to its lower price compared to other substances. In Western countries its use has been mainly linked to subpopulations of young people who use drugs recreationally. Ketamine misuse is associated with amnesia, dependence, dissociation, lower urinary tract dysfunction and poor impulse control. Regular ketamine use is associated with abdominal pains. AIMS: The aims of this study are to analyze characteristics and main symptoms of ketamine abusers attending emergency departments (EDs) in the metropolitan area of Bologna, Emilia-Romagna Region, northern Italy. METHODS: We identified 74 records of ketamine-related visits: 30% female; 22% non-natives; mean age 25.6 years. Forty-two percent reported ketamine use alone, 46% reported the use of other illegal substance (cocaine 19%, heroin 18%), 26% alcohol misuse. RESULTS: The most common reported symptoms were neurological (soporous state 18%, agitation 14%, confusion 7%, panic attacks 7%, mydriasis 7%, tremors 7%), gastro-intestinal (abdominal pain 15%, vomiting 11%), urological (6.8%) and cardiac (palpitations 5%, chest pain 5%). Complications secondary to falls and cuts (7%) were the most frequent trauma complications. We highlight a significant number of visits regarding suicide attempts (10%) and overdose (4%). CONCLUSIONS: The results highlight a particular population of problematic ketamine users identified using the hospital's ICT system. In particular, poly-drug users who consume ketamine in combination with heroin or cocaine presenting to the ED represent a specific target for targeted prevention projects on non-lethal overdoses and suicide attempts.

Who Are the Subjects with Gambling-Related Problems Requiring Treatment? A Study in Northern Italy.

BACKGROUND: This study analyzes data related to Hospital (HOS), Public Treatment Service Dedicated to Drug Addicts (SERD), or Community Mental Health Center (CMHC) clients with a first diagnosis of Pathological Gambling (PG) in the period 2000/2016 in Northern Italy. The aims were to describe trends and characteristics of pathological gamblers (PGs) and to estimate the prevalence of other diagnoses before or after the diagnosis of PG. METHODS: Participants aged over 17 years with an ICD-9 or ICD-10 PG diagnosis were selected. RESULTS: 680 PGs were identified, mean age 47.4 years, 20% female, 13% non-natives, 30% had other mental disorders diagnoses, 9% had alcohol dependence syndrome, and 11% had drug dependence. Most participants with comorbid disorders were diagnosed before PG, with a more elevated prevalence regarding mental disorders. Almost seven years had elapsed on average between the first admission and the diagnosis of PG. CONCLUSIONS: The results of this study highlight a growing demand for PG treatment addressed not only to SERD, but also to psychiatric and hospital services, based on the increase in SERD attendance from 2013. Many of them had already been treated for mental health problems before, but their percentage remained costant over time.
