Animal models are essential for understanding the biological factors that contribute to drug and alcohol addiction and discovering new pharmacotherapies to treat these disorders. Alcohol (ethanol) is the most commonly abused drug in the world, and as the prevalence of alcohol use disorder (AUD) increases, so does the need for effective pharmacotherapies. In particular, treatments with high efficacy in the growing number of female AUD sufferers are needed. Female animals remain underrepresented in biomedical research and sex differences in the brain's response to alcohol are poorly understood...

OBJECTIVE: Women whose sexual identity is not exclusively heterosexual are at risk for alcohol use disorder (AUD) and problematic drinking. A textual analytic approach focusing on motivated psychological distancing in language style use was used to detect sexual minority women who are at greatest risk for an AUD. METHOD: Young adult women (N = 254) were asked to complete a self-report measure of sexual orientation self-concept ambiguity as well as free-write about their sexuality...

Alcohol consumption is considered a major risk factor for disease and mortality worldwide. In the absence of effective treatments in alcohol use disorders, it is important to find new biological targets that could modulate alcohol consumption. We tested the role of the N-terminal galanin fragment (1-15) [GAL(1-15)] in voluntary ethanol consumption in rats using the two-bottle choice paradigm as well as compare the effects of GAL(1-15) with the whole molecule of GAL. We describe for the first time that GAL(1-15), via central mechanisms, induces a strong reduction in preference and ethanol consumption in rats...

Impulsivity is a personality trait associated with a heightened risk for drug use and other psychiatric conditions. Because impulsivity-related disorders typically emerge during adolescence, there has been interest in exploring methods for identifying adolescents that will be at risk to develop substance use disorders in adulthood. Here, we used a rodent model to assess inhibitory control (impulsive action) and impulsive decision making (impulsive choice) during adolescence (43-50 days old) or adulthood (93-100 days old) and then examined the impact of development on these impulsivity traits by re-testing rats 50 days later...

Working memory (WM) is a central construct in cognitive neuroscience because it comprises mechanisms of active information maintenance and cognitive control that underpin most complex cognitive behavior. Individual variation in WM has been associated with multiple behavioral and health features including demographic characteristics, cognitive and physical traits and lifestyle choices. In this context, we used sparse canonical correlation analyses (sCCAs) to determine the covariation between brain imaging metrics of WM-network activation and connectivity and nonimaging measures relating to sensorimotor processing, affective and nonaffective cognition, mental health and personality, physical health and lifestyle choices derived from 823 healthy participants derived from the Human Connectome Project...

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease, and the prevalence of non-alcoholic steatohepatitis (NASH) with fibrosis is increasing as the population with NAFLD ages. To date, lifestyle modifications including weight loss, increased physical activity, and dietary changes remain the treatment of choice for NAFLD because there are no approved effective pharmacologic agents. Increased physical activity has therapeutic effects on NAFLD by reducing hepatic fat independent of weight reduction...

Niall D Kennedy, Des C Winter
Alcohol and smoking are repeatedly described as modifiable risk factors in clinical studies across all surgical specialities. These lifestyle choices impart a sub-optimal physiology via multiple processes and play an important role in the surgical management of the gastrointestinal patient. Cessation is imperative to optimise the patient's fitness for surgery with surgery itself being a prime opportunity for sustained cessation. A consistent, planned and integrated management involving surgical, anaesthetic, medical, and primary care facets will aid in successful cessation and perioperative care...

Neuroeconomics is providing insights into the neural bases of decision-making in normal and pathological conditions. In the neuropsychiatric domain, this discipline investigates how abnormal functioning of neural systems associated with reward processing and cognitive control promotes different disorders, and whether such evidence may inform treatments. This endeavor is crucial when studying different types of addiction, which share a core promoting mechanism in the imbalance between impulsive subcortical neural signals associated with immediate pleasurable outcomes and inhibitory signals mediated by a prefrontal reflective system...

Individuals with a low initial response to alcohol (i.e., ethanol) are at greater risk of developing alcohol abuse or dependence later in life. Similar to humans, individual differences in ethanol sensitivity also can be seen in rats, and several laboratories have used these individual differences to generate selectively bred rats that differ in acute ethanol sensitivity. We have worked with two sets of such rats (Inbred High or Low Alcohol Sensitivity strains, IHAS or ILAS, respectively; Inbred Alcohol Tolerant or Non-Tolerant strains, IAT and IANT, respectively) and have confirmed previously mapped quantitative trait loci (QTL) for these acute differences with the use of recombinant congenic lines; however, the relationship between acute sensitivity and ethanol drinking in these rats has yet to be determined...

Introduction: Silibinin (silybin), a non-toxic natural polyphenolic flavonoid, is the principal and the most biologically active component of silymarin. It is efficient in the treatment of acute and chronic liver disorders caused by toxins, drug, alcohol, hepatitis, and gall bladder disorders. Further, in our previous studies, we explored the anti-cancer efficacy in common cancers, such as lung, prostatic, colon, breast, bladder, as well as, hepatocellular carcinoma. Interestingly, silibinin is still not solely limited to the treatment of these diseases...

Several factors are thought to contribute to inadequate seizure control in patients with juvenile myoclonic epilepsy (JME), including drug resistance, neuropsychiatric comorbidity, and poor lifestyle choices. Recent evidence supports the existence of frontal lobe microstructural deficits and behavioral changes that may contribute to poor seizure control in a minority of patients. Counseling patients on the importance of adequate sleep hygiene and alcohol restriction is an important part of the management strategy for patients with JME...

BACKGROUND: Varenicline, a partial agonist at α4β2 and full agonist at α7 nicotinic cholinergic receptors, is FDA approved for treatment of smoking cessation and has been found to reduce alcohol craving in clinical populations. In rodents, varenicline decreases free-choice ethanol intake with somewhat mixed findings in operant paradigms that utilize a combined appetitive/consummatory response. METHODS: The present experiment utilized an operant paradigm that procedurally separates appetitive from consummatory responding and a "reward blocking" approach (i...

Lipid-lowering therapy with statins reduces the risk of cardiovascular events, but the efficacy of persistent treatment in a real-world setting may vary from regions. Routine lipid-lowering therapy in the region with a high prevalence of cardiovascular disease may lead to more failures of goal attainment. We therefore performed a study to observe different lipid-lowering strategies in northeast (NE) China with respect to low-density lipoprotein-cholesterol (LDL-C) reduction and goal attainments.A cross-sectional study (DYSIS-China) was conducted in 2012, involving 25,317 patients from 122 centers across China who were diagnosed with hyperlipidemia and treated with lipid-lowering therapy for at least 3 months...

Different physical or chemical agents, such as noise or alcohol, can induce diverse behavioral and biochemical alterations. Considering the high probability of young people to undergo a successive or simultaneous exposure, the aim of the present work was to investigate in an animal model if noise exposure at early adolescence could induce hippocampal-related behavioral changes that might be modified after alcohol intake. MaleWistarrats(28-days-old)were exposed tonoise(95-97 dB, 2 h).Afterwards, animals were allowed to voluntarily drink alcohol(10% ethanol in tap water)for three consecutive days, using the two-bottle free choice paradigm...

Binge alcohol (ethanol) drinking is associated with profound adverse effects on our health and society. Rimonabant (SR141716A), a CB1 receptor inverse agonist, was previously shown to be effective for nicotine cessation and obesity. However, studies using rimonabant were discontinued as it was associated with an increased risk of depression and anxiety. In the present study, we examined the pharmacokinetics and effects of AM4113, a novel CB1 receptor neutral antagonist on binge-like ethanol drinking in C57BL/6J mice using a two-bottle choice drinking-in-dark (DID) paradigm...

BACKGROUND: A recent clinical trial found that pharmacological blockade of V1b receptors reduces alcohol relapse in alcohol-dependent patients. SSR149415 is a selective V1b receptor antagonist that has potential for development as an alcohol dependency treatment. In this study, we investigated whether SSR149415 alone or in combination with the mu-opioid receptor [MOP-r] antagonist naltrexone (NTN) would alter excessive alcohol drinking in mice. METHODS: Both sexes of C57BL/6J (B6) mice were subjected to a chronic intermittent access (IA) drinking paradigm (two-bottle choice, 24-h access every other day) for 3 weeks...

Non-alcoholic fatty liver disease (NAFLD) is a disease of increasing interest as its prevalence is on the rise. NAFLD has been linked to metabolic syndrome, which is becoming more common due to the Western diet. Since NAFLD can lead to cirrhosis and related complications including hepatocellular carcinoma, the increasing prevalence is concerning and medical therapy aimed at treating NAFLD is of great interest. Researchers studying the effects of medical therapy on NAFLD use dietary mouse models. The two main types of mouse model diets are the methionine- and cholinedeficient (MCD) diet and Western-like Diet (WD)...

INTRODUCTION: The severity of emotional responses to life events (PTSD spectrum) as part of Post Traumatic Stress Disorder (PTSD) in Substance Use Disorder (SUD) patients has often been considered from a unitary perspective. Light has also been shed on the possible definition of a specific psychopathology of SUD patients. This psychopathology has been proved to be independent of treatment choice, of being active in using substances, of lifetime psychiatric comorbidity and primary substance of abuse (heroin, alcohol, cocaine)...
