RESUMO
Currently, few treatments are available for craving in general, and none of them have received approval for cannabis craving. The objective of this review is to evaluate existing studies analysing treatments for cannabis craving and explore novel treatment possibilities for these patients. The study followed PRISMA guidelines and conducted an extensive database search. Inclusion criteria included human randomised controlled trials examining drug effects on craving symptoms. Exclusion criteria involved studies unrelated to craving, non-pharmacological treatments, duplicates, and non-English/Spanish/Portuguese articles. Our included 22 studies that investigated a wide range of compounds used for cravings related to other drugs, as well as interventions based on healthcare professionals' empirical knowledge. The current pharmacological treatments largely involve off-label drug use and the utilisation of cannabinoid-based medications, such as combinations of THC and lofexidine, oxytocin, progesterone, and N-acetylcysteine. These emerging treatments show promise and have the potential to revolutionise current clinical practices, but further investigation is needed to establish their efficacy. In this context, it is essential to consider non-pharmacological interventions, such as psychotherapy and behavioural treatments. These approaches play a crucial role in complementing pharmacological interventions and addressing the complex nature of the disorder.

The adverse effects of smoking cessation in individuals with mental health disorders have been a point of concern, and progress in the development of treatment has been slow. The primary first-line treatments for smoking cessation are Nicotine Replacement Therapy, Bupropion, Varenicline, and behavioural support. Nortriptyline and Clonidine are second-line treatments used when the first-line treatments are not effective or are contraindicated. Smoking cessation medications have been shown to be effective in reducing nicotine cravings and withdrawal symptoms and promoting smoking cessation among patients living with mental disorders. However, these medications may have implications for patients' mental health and need to be monitored closely. The efficacy and side effects of these medications may vary depending on the patient's psychiatric condition, medication regimen, substance use, or medical comorbidities. The purpose of this review is to synthesise the pharmacokinetics, pharmacodynamics, therapeutic effects, adverse effects, and pharmacological interactions of first- and second-line smoking cessation drugs, with an emphasis on patients suffering from mental illnesses. Careful consideration of the risks and benefits of using smoking cessation medications is necessary, and treatment plans must be tailored to individual patients' needs. Monitoring symptoms and medication regimens is essential to ensure optimal treatment outcomes.

Substance use disorder (SUD) assessment and measurement in Brazil, as well as in many other countries, face significant shortcomings. The Measurement in the Addictions for Triage and Evaluation (MATE) was developed as a public domain tool, drawing from validated scales and incorporating World Health Organization International Classification of Functioning, Disability, and Health (ICF) framework. The Brazilian version of the MATE (MATE-pt-BR) was evaluated for its reliability and validity, with a total of 239 subjects participating in the study, and data collected between 11/01/2021 and 09/01/2022. The majority were male (79.2%), with diverse racial backgrounds. The substances most prevalently used in the last 30 days were. Alcohol (73.2%), nicotine (63.6%), and cocaine (44.2%). The mean scores for MATE modules showed variations, with Module Q2 assessing psychological well-being having high internal consistency (Cronbach's alpha = 0.92). MATE-pt-BR demonstrated robust internal consistency, with Module 6 (personality) and Module 2 (medical and psychiatric consultation indicators) being exceptions. MATE-pt-BR exhibited significant correlations among its sections and strong discriminant validity. Moreover, the paper compares MATE-pt-BR with the Addiction Severity Index (ASI-6), which is considered the gold-standard measure for SUD assessments. MATE-pt-BR offers a valuable tool for assessing substance use and related functional impairments in the Brazilian context.

Tobacco use is associated with an annual global economic cost of two trillion dollars and mortality of half of its regular users. Tobacco leaf cultivation is the starting point of the tobacco cycle. Tobacco farming employs millions of small-scale tobacco farmers around the globe, most of whom are out growers who rely on the tobacco industry. This paper aims to map the regions of greatest tobacco production globally (i.e., the US, Brazil, China, Indonesia, India, and Zambia) and tobacco use rates in these locations. Smoking rates were higher in those areas, except for India, where important population subgroups reported an upward trend for tobacco smoking. In general, there was a relationship between tobacco farming and tobacco smoking. Tobacco farming may lead to a higher risk of tobacco use and lower adherence to tobacco control policies. Therefore, promoting viable alternative livelihoods for tobacco farmers must have dual benefits. Additionally, specific health prevention policies might be necessary for those populations reporting higher tobacco use and lower perception of tobacco-related health risks.

This review aims to summarize neuroimaging studies in order to better understand the neural correlates of depressive symptoms in tobacco smokers. Using the keywords "depressive OR depression" AND "tobacco OR nicotine OR smok* OR cigarette" AND "neuroimage OR magnetic resonance OR smri OR structural magnetic resonance OR fmri OR functional magnetic resonance OR pet OR positron emission tomography", literature search was conducted in PubMed, Web of Science and PsycINFO databases. The first and the last author read the abstracts of all the studies found in the search (n = 179). The inclusion and exclusion criteria were applied and 150 articles were excluded. Then, both authors assessed the remaining 29 studies for eligibility and 16 studies were included in the present review. In the phase of active/chronic smoking, depressive symptoms are characterized as comorbidity related to an enhancement of dopamine release, and smokers have decreased Monoamine oxidase A (MAO-A). Stimuli-related functional magnetic resonance imaging (Stimuli-fMRI) studies also show that there is a positive correlation between the level of depressive symptoms and a greater response to general negative stimuli in active/chronic smokers. In the withdrawal phase, depressive symptoms are related to the withdrawal syndrome and increased MAO-A. Stimuli-fMRI studies show that there is a negative correlation between level of depressive symptoms and reactivity to negative stimuli in recent abstinent smokers. Major areas of the reward system such as the striatum and areas related to impulse control are activated to a greater extent in depressive smokers compared to non-depressed smokers.

BACKGROUND: Pandemic fatigue generates low motivation or the ability to comply with protective behaviors to mitigate the spread of COVID-19. AIMS: This study aimed to analyze the symptoms of pandemic fatigue through network analysis in individuals from five South American countries. METHOD: A total of 1,444 individuals from Argentina, Bolivia, Paraguay, Peru, and Uruguay participated and were evaluated using the Pandemic Fatigue Scale. The networks were estimated using the ggmModSelect estimation method and a polychoric correlation matrix was used. Stability assessment of the five networks was performed using the nonparametric resampling method based on the case bootstrap type. For the estimation of network centrality, a metric based on node strength was used, whereas network comparison was performed using a permutation-based approach. RESULTS: The results showed that the relationships between pandemic fatigue symptoms were strongest in the demotivation dimension. Variability in the centrality of pandemic fatigue symptoms was observed among participating countries. Finally, symptom networks were invariant and almost identical across participating countries. CONCLUSIONS: This study is the first to provide information on how pandemic fatigue symptoms were related during the COVID-19 pandemic.

The COVID-19 pandemic has had a heavy impact on daily life, leading to physical and psychosocial consequences. Nowadays, clinicians and health researchers are particularly interested in describing and facing the long-term effects of COVID-19, also known as "long-COVID syndrome". Pandemic fatigue has been defined as a cluster of demotivation, tiredness, and psychological effects that emerge gradually over time after the infection or through the adoption of the recommended measures to combat it. In this study, we report the findings of a large survey conducted in South America involving 1448 participants (mean age: 33.9 ± 11.2 years old) from Argentina, Bolivia, Uruguay, Peru, and Paraguay. An online survey was launched through the common social media based on a specific assessment aimed to detect the prevalence of pandemic fatigue and associated factors. Socio-demographic characteristics, medical, and personal information were collected; the Pandemic Fatigue Scale (PFS) and the Coronavirus Anxiety Scale (CAS) were also administered. We found mid-levels of pandemic fatigue among respondents (21.7 ± 7.95 score at PFS) as well as significant anxiety related to the COVID-19 pandemic (1.56 ± 2.76 score at CAS). In addition, pandemic fatigue was significantly associated with the experience of the loss of a relative/friend due to COVID-19, anxiety related to the infection, and reliance on social media as a primary source of information on the pandemic. Vaccination significantly reduced the levels of fatigue among respondents. Our findings may add to the international debate regarding the long-term health consequences of the COVID-19 pandemic and strategies to manage them in the general population of South America.
