Prenatal alcohol exposure (PAE) can result in a range of adverse neonatal outcomes, including Fetal Alcohol Spectrum Disorder (FASD). This systematic review and meta-analysis sought to investigate the effectiveness of brief interventions (BIs) in eliminating or reducing 1) alcohol consumption during pregnancy; and 2) PAE-related adverse neonatal outcomes; and 3) cost-effectiveness of BIs. We conducted a systematic literature search for original controlled studies (randomized control trials (RCTs); quasi-experimental) in any setting, published from 1987 to 2021. The comparison group was no/minimal intervention, where a measure of alcohol consumption was reported. Studies were critically appraised using the Centre for Evidence-based Medicine Oxford critical appraisal tool for RCTs (1). The certainty in the evidence for each outcome was assessed using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) (2). Meta-analysis of continuous and binary estimates of effect-size for similar outcome measures for BIs versus control groups were pooled and reported as mean difference (MD) Hedges' g and odds ratios (ORs), respectively. In total, 26 studies, all from high income countries, met inclusion criteria. Alcohol abstinence outcome available in 12 studies (n = 2620) found modest effects in favor of BIs conditions by increasing the odds of abstinence by 56% (OR = 1.56, 95% confidence interval (CI) = 1.15-2.13, I = 46.75%; p = 0.04). BIs effects for reduction in mean drinks/week (Cohen's d = - 0.21, 95%CI = - 0.78 to 0.36; p = 0.08) and AUDIT scores (g = 0.10, 95%CI = - 0.06 to 0.26; p = 0.17) were not statistically significant. Among seven studies (n = 740) reporting neonatal outcomes, BI receipt was associated with a modest and significant reduction in preterm birth (OR = 0.67, 95% CI = 0.46-0.98, I = 0.00%; p = 0.58). No statistically significant differences were observed for mean birthweight or lower likelihood of low birth weight (LBW). Certainty

COVID-19 has had a great impact on mental health in the general population. However, few studies have focused on patients with substance use disorders (SUDs). This research aimed to compare the clinical status and substance use patterns of SUD outpatients, before and during confinement due to the COVID-19 pandemic. This multicentre study recruited 588 patients (29.2% women; M age = 47.4 ± 11.7 years) in thirteen centres for addiction treatment in Catalonia, Spain. All subjects were evaluated with validated instruments and ad hoc questionnaires. The sample was divided into 3 groups according to how the substance consumption pattern changed during lockdown (maintained pattern, worsened pattern, and improved pattern). More than 62% of the patients maintained or worsened their consumption pattern during confinement, and about 38% improved throughout this time. Diverse factors were associated with the changes in pattern like age, addiction severity, psychological distress during lockdown, social and familial issues, and therapeutic variables. The home lockdown during the COVID-19 pandemic was associated with major implications for substance consumption and psychiatric distress among SUD outpatients. Considering this, the need to plan appropriate interventions in cases of similar health crises is highlighted

Heavy episodic drinking, or binge drinking, is a drinking pattern characterized by the intake of large amounts of alcohol in a short period of time, which often leads to alcohol intoxication. There is no consensus on its operational definition, finding large methodological differences between studies in estimating the amount of alcohol consumed, as well as in defining the occasion of drinking and the reference time period. Keep in mind that most drinkers with this pattern have a low risk total average alcohol consumption. Therefore, actively detecting binge drinking is essential to be able to identify and classify all risk drinkers and characterize the global impact of alcohol consumption on health, society or the economy. Its negative effects affect the drinker himself (intoxication, cardiovascular diseases, dependence, neurocognitive and developmental disorders, among others), but also causes harm to others (accidents, violence, harmful effects on fetal and perinatal neuronal development). These effects can be acute or chronic, even among those who adopt binge drinking sporadically. Different thresholds or ways of characterizing this pattern of alcohol consumption could more adequately predict each of the associated acute and chronic effects, especially if we consider the intensity and frequency of the episodes. However, the absence of a safe threshold for alcohol consumption, both regularly and occasionally, is clear; Any intake with a binge drinking pattern, regardless of the threshold we establish, carries significant risks, not only for the health of the drinker, but also for the people around them., El patrón de episodios de consumo intensivo de alcohol o binge drinking, se caracteriza por la ingesta de grandes cantidades de alcohol concentrada en un corto espacio de tiempo, que comporta con frecuencia una intoxicación alcohólica. No existe consenso en su definición operativa, hallando entre los estudios grandes diferencias metodológicas en la estimación de la cantidad de alcohol consumido, así como en la definición de la ocasión de bebida y el periodo temporal de referencia. Hay que tener en cuenta que una mayoría de los bebedores con este patrón tienen un consumo de alcohol promedio total de bajo riesgo. Por ello, detectar de forma activa el patrón de consumo intensivo episódico, resulta fundamental para poder identificar y clasificar a todos los bebedores de riesgo y caracterizar el impacto global del consumo de alcohol en la salud, la sociedad o la economía. Sus efectos negativos afectan al propio bebedor (intoxicación, enfermedades cardiovasculares, dependencia, alteraciones neurocognitivas y de maduración entre otros), pero también potencialmente a terceras personas (accidentes, violencia, efectos perjudiciales en el desarrollo neuronal fetal y perinatal). Estos efectos se pueden manifestar de forma aguda, pero también crónica, incluso entre los que adoptan el binge drinking de forma esporádica. Distintos umbrales o formas de caracterizar este patrón de consumo de alcohol podrían predecir de forma más adecuada cada uno de los efectos agudos y crónicos asociados, especialmente si consideramos la intensidad y la frecuencia con que se adopta. No obstante, resulta clara la ausencia de un umbral seguro de consumo de alcohol, tanto de forma regular como puntual; cualquier ingesta con un patrón binge drinking, con independencia del umbral que establezcamos, comporta riesgos importantes, no solo para la salud del bebedor, sino también para las personas de su entorno.

Background: There is great controversy about whether the consumption of different types of alcoholic beverages has different effects on health. The objective was to carry out an umbrella review of the studies that described the association between the consumption of different types of alcoholic beverages and various health indicators. Methods: Search through PubMed (from January 2000 to February 2019) of systematic reviews and meta- analysis that reported quantitative results of the association between the consumption of different types of alcoholic beverages and health effects. 26 studies were identified: 21 related to cancer, three to cardiometabolic diseases, two to neurodegenerative diseases, and one to general mortality. Results: The results were heterogeneous. The great methodological differences in the estimation of alcohol intake, control of confounding variables, and the evaluation of statistical difference between types of beverages, made it very difficult to conclude whether they cause an unequal effect on health. In general mortality and cardiometabolic diseases, it was suggested that beer and spirits appear to have a greater negative effect than wine, but the differences were not statistically significant. Regarding cancer, in those types where the causal evidence is totally consistent: oropharynx, colorectal and breast (women), the reviews did not show a differentiated effect according to the type of alcoholic beverages. Regarding neurodegenerative diseases, the available information did not allow clear conclusions to be drawn. Conclusions: The reviewed evidence does not allow to conclude that the consumption of wine, beer or spirits, has a differential effect on cardiometabolic, cancer or neurodegenerative diseases., Fundamentos: Existe gran controversia sobre si el consumo de diversos tipos de bebidas alcohólicas tiene efectos diferenciados en la salud. El objetivo de este estudio fue realizar una revisión paraguas de los estudios que describían la asociación del consumo de diferentes tipos de bebidas alcohólicas con diversos indicadores de salud. Métodos: Se realizó una búsqueda a través de PubMed (entre enero de 2000 y febrero de 2019) de revisiones sistemáticas y metaanálisis que reportaban resultados cuantitativos de la asociación entre el consumo de diferentes tipos de bebidas alcohólicas y efectos en salud. Se identificaron 26 estudios: veintiuno estaban relacionados con cáncer, tres con enfermedades cardiometabólicas, dos con neurodegenerativas y uno con mortalidad general. Resultados: Los resultados fueron heterogéneos. Las grandes diferencias metodológicas en la estimación de la ingesta de alcohol, el control de las variables confusoras y el contraste de las estimaciones entre el tipo de bebidas hacían muy difícil concluir sobre si provocaban un efecto desigual en la salud. En la mortalidad general y las enfermedades cardiometabólicas, aunque parece que la cerveza y los licores tenían un mayor efecto negativo que el vino, las diferencias entre tipos de bebidas no eran estadísticamente significativas. Respecto al cáncer, en aquellos tipos cuya evidencia causal era totalmente consistente (orofaringe, colorrectal y de mama [mujeres]), las revisiones no mostraban un efecto diferenciado según los tipos de bebidas alcohólicas. Respecto a las enfermedades neurodegenerativas, la información disponible tampoco permitía establecer claras conclusiones. Conclusiones: La evidencia revisada no permite afirmar que el consumo de vino, cerveza o licores tenga un efecto diferencial en las enfermedades cardiometabólicas, las neurodegenerativas o el cáncer.

This work places in context Spain’s recent update of the defined limits for low risk alcohol consumption to 20g/day for men and 10g/day for women, and summarises data on the impact on individual health and the social costs of alcohol consumption. Furthermore, it considers the challenges that arise related to awareness of the risks of alcohol consumption, in the general population and among health professionals. The paper also reviews the implications of the new definitions in relation to the most effective policies for reducing alcohol-related harm. It looks at this from a public health perspective with particular emphasis on how to seize the opportunity to better promote the implementation of strategies for early identification and brief interventions in primary care in this country., Este trabajo pone en contexto la reciente actualización para España de los limites de bajo riesgo del consumo de alcohol, que se sitúa en los 20 g/día en el caso de los hombres, y en 10 g/día en el caso de las mujeres. En este sentido, se resumen algunos datos sobre el impacto en la salud individual y los costos sociales del consumo alcohol. Así mismo, plantea los retos que se derivan en relación a la alfabetización en salud de la población y de los profesionales de la salud en cuanto a los riesgos del consumo de alcohol. El artículo también repasa las implicaciones de la nueva definición en cuanto a las políticas más rentables para disminuir los daños asociados al consumo de alcohol. Este repaso se hace desde una perspectiva de salud pública, haciendo especial hincapié en cómo aprovechar la oportunidad para promover mejor la implementación de las estrategias de identificación precoz e intervención breve en el consumo de alcohol en el ámbito de la atención primaria de salud en nuestro país.
