Alcohol-related cognitive impairment (ARCI) is highly prevalent among patients with alcohol dependence. Although it negatively influences treatment outcome, this condition is underdiagnosed and undertreated. The aim of this systematic review is to investigate the existing evidence regarding both cognitive and pharmacological interventions for ARCI. We systematically reviewed PubMed, Scopus and Science direct databases up to May 2019 and followed the PRISMA guidelines. The quality of the studies was assessed using the Jadad Scale. Twenty-six studies were eligible for inclusion (14 referring to neuropsychological interventions and 12 to pharmacological treatments). Among neuropsychological interventions, computerised treatments, errorless learning and component method showed positive effects on working memory, memory measures and general cognitive function. On the other hand, thiamine, memantine and methylphenidate improved working memory, long-term memory and general cognitive function. Nevertheless, these studies have several limitations, such as small sample size, lack of replication of the results or low specificity of the interventions. Therefore, no gold-standard intervention can yet be recommended for clinical practice, and further research based on promising strategies (e.g. digital interventions, thiamine) is required.

Tobacco use is more prevalent among alcohol liver disease (ALD) transplant patients and exerts harmful effects to the patient and to the graft. The aims of this study were to examine the impact of smoking status (nonsmoker, ex-smoker, active smoker) on patient survival and clinical outcomes, and to assess risk factors for active smoking before and after liver transplant (LT). An observational retrospective cohort study with 314 ALD patients undergoing LT from January 2004 to April 2016. Recipients were followed until April 2017 or death. Kaplan–Meier and Cox proportional hazards regression analyses were used to assess risk of mortality according to smoking status before LT. Smokers had a 79% higher risk of dying than those who had never smoked or quit smoking before LT. Ex-smokers had a greater survival probability (96.2%, 93.8%, 86.9%, and 83.1% at 1, 3, 5, and 10 years after LT) than active smokers until LT (96.0%, 85.6%, 80.0%, and 70.4%). Active smokers before LT with poor toxicity awareness had more than a twofold higher risk of mortality (Cox HR = 2.20, 95% CI: 1.05–4.58, p = 0.04) than ex-smokers. Younger age (OR = 94), higher Model for End-Stage Liver Disease (MELD) (OR = 1.06), and comorbid substance use disorder (OR = 2.35) were predictors of smoking until LT. Six months or less of alcohol abstinence (OR = 3.23), and comorbid substance use disorder (OR = 4.87) were predictors of active smoking after LT. Quitting smoking before transplantation improved survival. Evidence based smoking cessation interventions should be offered before and after LT.

No- and low-alcohol drinks (NoLo) have been proposed as a potential way forward for the reduction in the alcohol burden of disease. So far, there is scarce synthesized evidence on the effects of these products on people with alcohol use disorder (AUD), or with a heavy or high-risk drinking pattern. The aim of the present study is to systematically review the evidence of the use of NoLo drinks in these populations. A total of 4045 records were screened and 10 studies were included in the review. Craving and desire to drink have been found to increase after the consumption of NoLo drinks in patients with AUD. The increase in craving correlates with the severity of alcohol dependence. In addition, in this population, alcohol-related cues might trigger physiological responses similar to those experienced when using alcohol. Furthermore, as mentioned, in some of the studies, consumption was shown to increase as the %ABV or verbal descriptors indicate lower alcohol. Last, according to the epidemiological data, heavy drinkers tend to use NoLo drinks on top of their usual alcohol consumption rather than as part of regular drinking patterns. Further studies should be conducted in people with AUD or people with a high-risk drinking pattern to provide new insight to guide clinicians, patients, and other stakeholders to make evidence-based informed decisions.

Purpose of reviewThe purpose of this update is to provide an overview of recent research publications (January 2020--January 2022) on real-time telemedicine solutions for the management of addictions (alcohol, tobacco, opioids, and other drugs). Recent findingsMotivational interviewing by real-time telemedicine showed effectiveness in youth and adults for risky alcohol use and alcohol use disorders, even when a concurrent mental health disorder exists. Live telemedicine is well accepted for managing tobacco use disorders. The range of interventions for treating opioid use disorder by real-time telemedicine is large and has been increased due to the coronavirus disease 2019 (COVID-19) pandemic (prescription of opioid agonists, peer-to-peer support, counseling, and group therapy).
