Assessment of depression, anxiety, stress, alcohol dependence, and resilience in migrant workers during COVID-19 crisis.

During the COVID-19 pandemic, migrant workers in India have gone through many hardships. After the lockdown, many construction sites, factories, and workplaces shut down, and innumerable migrant workers faced a loss of income, shortage of food, and uncertain future. This massive change in their living conditions made them vulnerable to psychological problems. To screen for depression, anxiety, stress, alcohol dependence, and resilience in migrant workers during the COVID-19 crisis. Migrant workers at seven camps in the Pimpri Chinchwad Municipal Corporation, Maharashtra, were surveyed with the help of the Depression Anxiety Stress (DASS-21) Scale to assess depression, anxiety, and stress levels, AUDIT C for assessing alcohol use disorders, and Connor-Davidson resilience scale short form (CD RISC) for assessing resilience. A total of 1053 migrant workers were surveyed. It showed that 57.54% of workers had depressive symptoms, 64.96% had anxiety symptoms, and 39.32% had subjective stress. Female migrant workers had more severe depression, anxiety, and stress symptoms as compared to males while male workers were more at risk of alcohol use disorder as compared to females. Migrants without family had more symptoms of severe depression and alcohol use disorder as compared to those with family. Regression analysis showed that levels of anxiety were independently associated with female gender, unmarried status, stress, depression, and alcohol use disorder while resilience negatively predicted anxiety in these migrant workers. During the COVID-19 pandemic, migrant workers were at risk of depression, anxiety, stress, and alcohol use disorder. Females and migrants without families came out to be more vulnerable to these psychological problems. Hence during the pandemic situation, identifying this vulnerable population and special preventive or therapeutic programs for them can be of crucial importance.

Recollecting a previous drinking episode reduces subsequent motivation for alcohol in females

Research has consistently demonstrated the effects of alcohol on memory, but the extent to which memory influences prospective drinking behaviour has not been studied extensively. Here, we adapt and extend theory from the food domain to explore whether memory for a previous drinking episode can reduce the motivation to consume alcohol. Female participants (N = 50) completed the Alcohol Use Disorder Identification Test (AUDIT) and were then cued to recall either a previous alcohol drinking episode and estimate the number of alcohol calories consumed (Alcohol Cue, AC) or a control (Neutral Cue, NC). They then consumed an alcoholic beverage in their own time followed by providing an estimate of subsequent alcohol intake. We found that the duration to finish the drink was longer in the AC versus NC condition. Additionally, irrespective of condition, those individuals at a higher alcohol (AUDIT) risk, consumed the drink at a faster rate and wished to consume more subsequent alcohol. These findings suggest that for females, memory for a previous drinking alcohol episode, reduces subsequent desire for alcohol and could offer a potentially useful way to help avoid excess alcohol consumption.

Greater inhibition of female rat binge alcohol intake by adrenergic receptor blockers using a novel Two-Shot rat binge drinking model

Binge drinking (BD) contributes strongly to the harms of alcohol use disorder. Most rodent models do not result in binge-level blood alcohol concentrations (BACs), and to better understand individual and sex differences in neurobiological mechanisms related to BD, the use of outbred rat strains would be valuable. Here, we developed a novel BD model where after 3+ months of intermittent access to 20% alcohol Wistar rats drank, twice a week, with two 5-min intake (what we called Two-shot) separated by a 10-min break. Our findings showed during Two-Shot that most animals reached ≥ 80 mg% BAC levels (when briefly food-restricted). However, when increasing alcohol concentrations from 20 to 30%, 40%, or 50%, rats titrated to similar intake levels, suggesting rapid sensing of alcohol effects even when front-loading. Two-Shot drinking was reduced in both sexes by naltrexone (1 mg/kg), validating intake suppression by a clinical therapeutic agent for human problem drinking. Further, both propranolol (β-adrenergic receptor antagonist) and prazosin (α1-adrenergic receptor antagonist) reduced female but not male BD at the lower dose. Thus, our results provide a novel model for BD in outbred rats and suggest that female binging is more sensitive to adrenergic modulation than males, perhaps providing a novel sex-related therapy.

Maternal alcohol drinking patterns predict offspring neurobehavioral outcomes

The timing, rate, and quantity of gestational alcohol consumption, collectively referred to here as Maternal Drinking Patterns (MDPs), are of known importance to fetal developmental outcomes. However, few studies have directly evaluated the impact of MDPs on offspring behavior. To do so, we used specialized equipment to record the precise amount and timing of alcohol consumption in pregnant dams, and then characterized MDPs using Principle Component Analysis (PCA). We next tested offspring on behaviors we have previously identified as impacted by prenatal alcohol exposure, and evaluated them where possible in the context of MDPs. Male alcohol exposed mice exhibited longer latencies to fall on the rotarod compared to their controls, which we attribute to a delayed decrease in body weight-gain. This effect was mediated by MDPs within the first 15 min of alcohol access (i.e. alcohol frontloading), where the highest performing male offspring came from dams exhibiting the highest rate of alcohol frontloading. Female alcohol exposed mice displayed reduced locomotor activity in the open field compared to controls, which was mediated by MDPs encompassing the entire drinking session. Surprisingly, total gestational alcohol exposure alone was not associated with any behavioral outcomes. Finally, we observed allodynia in alcohol exposed mice that developed more quickly in males compared to females, and which was not observed in controls. To our knowledge, this report represents the highest resolution assessment of alcohol drinking throughout gestation in mice, and one of few to have identified relationships between specific alcohol MDPs and neurobehavioral outcomes in offspring.

Predictive Factors and Timing of Developing Anal Fistula after Drainage of Cryptoglandular Anorectal Abscess: A Retrospective Cohort Study

Background: Cryptoglandular infection is one of the main causes of common anorectal infections that presents in conjunction with abscess following anal fistula after drainage. Objective: To evaluate the rate and predictive factors of fistula formation following anorectal abscess drainage, and the timing of fistula diagnosis. Materials and Methods: The present study was a retrospective study of 232 patients with cryptoglandular anorectal abscess that underwent drainage in the operating room under anesthesia between 2010 and 2019. The predictive factors of fistula development were analyzed using Cox’s proportional hazard. Results: Seventy out of 232 patients (30%) developed anorectal fistula after drainage of anorectal abscess. Median follow-up time was 35.5 months, and 25.02% (95% CI 19.89 to 31.19) of patients developed fistula within 12 months after the surgery. Independent factors in developing anal fistula after drainage were female gender (HR 2.17, 95% CI 1.15 to 4.14, p=0.017), alcohol consumption (HR 2.24 95% CI 1.20 to 4.22, p=0.012), and driver (HR 2.80, 95% CI 1.08 to 7.25, p=0.034). The protective factors are gauze packing (HR 0.43, 95% CI 0.23 to 0.82, p=0.009) and identifiable organism from pus culture (HR 0.59, 95% CI 0.36 to 0.99, p=0.046). Conclusion: After drainage of a cryptoglandular anorectal abscess, there is a need to raise the awareness concerning anorectal fistula in female patient, alcohol drinkers, and those who work as drivers. Bacterial cultures should be taken, and gauze drain should be positioned. The potential fistula formation should be monitored in the first year after the operation with an option of extending to a second year.

Validation of the extinction probe trial as a measure of motivation in male and female Long Evans rats.

Ethanol self-administration is governed by appetitive and consummatory behaviors. The sipper model procedurally separates these behaviors by training rats to meet a response requirement within 20 min to obtain continuous access to a sipper tube for an additional 20 min. Variations of this paradigm have been developed to quantify appetitive strength by evaluating lever presses during an extinction probe trial (EPT) or by deriving a break point (BP) from a progressive ratio (PR) schedule of reinforcement. However, no study has assessed the relationship between these tasks, within subjects, in both sexes. Male and female rats (n = 16) were trained to meet a response requirement of 20 to access a slightly sweetened ethanol solution (10% ethanol + 1% sucrose). Two EPTs, during which no operant behavior was reinforced, were interleaved between 18 reinforced sessions. Next, rats completed an across-session PR schedule, where the response requirement increased each session. BP was defined as the highest completed response requirement. We then replicated the methodology in the same subjects responding for a 3% sucrose solution. Finally, the experiment was replicated in a separate cohort of rats (n = 24) trained to a response requirement of 4 to earn access to the ethanol solution and paradigm order (EPT vs. PR) was counterbalanced. We report strong, positive correlations between average EPT lever presses and BP across all experiments. No sex differences were observed in appetitive behaviors. However, the two cohorts revealed mixed results when assessing sex differences in consummatory measures. This study further validates the EPT as a measure of motivation and suggests that similar levels of motivation exist to procure alcohol in males and females. The findings complement the literature showing that appetitive and consummatory processes are distinct and thus should be independently assessed in self-administration paradigms.

Binge Drinking and its Relationship with Suicidal Thoughts and Suicidal Attempts in University Students

AbstractBinge drinking, notably common among university students, poses health risks. Despite a significant global concern about suicide, especially among young people, research on the connection between binge drinking and suicide in university students is limited. This cross-sectional study investigated the relationship between binge drinking, suicidal attempts, and suicidal thoughts among university students from two institutions. Among the 2178 participants from public universities, 4.0% reported suicidal attempts, and 26.5% reported suicidal thoughts. Binge drinking did not show a significant association with suicidal attempts or suicidal thoughts. The results revealed that female gender (OR 1.62, 95% CI: 1.32–2.01; p < 0.001) and alcohol use disorder (OR 2.23, 95% CI: 1.49–3.55; p < 0.001] were independent predictive variables for suicidal behavior. These findings underscore the need for targeted interventions addressing alcohol-related behaviors and mental health, particularly among females and those with alcohol use disorder, to enhance the overall psychological well-being of university students.

Sex differences in heart rate variability measures that predict alcohol drinking in rats.

Problem alcohol drinking continues to be a substantial cost and burden. In addition, alcohol consumption in women has increased in recent decades, and women can have greater alcohol problems and comorbidities. Thus, there is a significant need for novel therapeutics to enhance sex-specific, individualized treatment. Heart rate (HR) and HR variability (HRV) are of broad interest because they may be both biomarkers for and drivers of pathological states. HRV reflects the dynamic balance between sympathetic (SNS, 'fight or flight') and parasympathetic (PNS, 'rest and digest') systems. Evidence from human studies suggest PNS predominance in women and SNS in men during autonomic regulation, indicating the possibility of sex differences in risk factors and physiological drivers of problem drinking. To better understand the association between HRV sex differences and alcohol drinking, we examined whether alcohol consumption levels correlated with time domain HRV measures (SDNN and rMSSD) at baseline, at alcohol drinking onset, and across 10min of drinking, in adult female and male Wistar rats. In particular, we compared both HRV and HR measures under alcohol-only and compulsion-like conditions (alcohol + 10mg/L quinine), because compulsion can often be a significant barrier to treatment of alcohol misuse. Importantly, previous work supports the possibility that different HRV measures could be interpreted to reflect PNS versus SNS influences. Here, we show that females with higher putative PNS indicators at baseline and at drinking onset had greater alcohol consumption. In contrast, male intake levels related to increased potential SNS measures at drinking onset. Once alcohol was consumed, HR predicted intake level in females, perhaps a pharmacological effect of alcohol. However, HRV changes were greater during compulsion-like intake versus alcohol-only, suggesting HRV changes (reduced SNS in females, reduced PNS and increased HR in males) specifically related to aversion-resistant intake. We find novel and likely clinically relevant autonomic differences associated with biological sex and alcohol drinking, suggesting that different autonomic mechanisms may promote differing aspects of female and male alcohol consumption.

The association between brominated flame retardants exposure with bone mineral density in US adults: A cross-sectional study of the national health and nutrition examination survey (NHANES) 2005–2014

Background and aimsExposure to brominated flame retardants (BFRs) has been widely confirmed to impair the normal functioning of the human body system. However, there is a paucity of study on the effects of serum BFRs on bone mineral density (BMD). This study aims to investigate the relationship between exposure to BFRs and BMD in a nationally representative sample of U.S. adults. Methods3079 participants aged between 20 and 80 years with complete data were included in the study. Serum levels of BFRs were measured using automated liquid-liquid extraction and subsequent sample clean-up. The BMD of all participants were assessed by DXA examinations. Generalize linear model, Restricted cubic spline (RCS), subgroup, weighted quantile sum (WQS) and bayesian kernel machine regression (BKMR) were used to estimate the association between serum BFRs and BMD. ResultsMultivariate linear regression analyses revealed that, after adjusting for covariates, PBB153 was significantly associated with TF-BMD (β = 0.0177, 95%CI: 0.0103–0.0252), FN-BMD (β = 0.009, 95%CI: 0.0036–0.0145), TS-BMD (β = 0.0081, 95%CI: 0.0013–0.015) and L1-BMD (β = 0.0144, 95%CI: 0.0075–0.0213). However, the associations lose their statistical significance after further adjustment for sex. BFRs exhibited S-shaped or line-plateau dose-response curves with BMD. In subgroup analyses, BFRs were significantly associated with BMD in participants who were younger than 55 years, female, overweight (BMI >25 kg/m2), and less alcohol consumption. In WQS and BKMR analyses, the effects of BFRs mixtures on BMD differed by sex, and PBDE153, PBDE209 and PBB153 had the highest weights in the WQS regression model. ConclusionThis study showed that serum BFRs negatively predicted BMD in men, but not in women or the general population. PBDE153, PBDE209, and PBB153 were significant BMD factors, especially in younger, overweight, and less alcohol consumption individuals.

Lifestyle factors, viral hepatitis, and hepatocellular carcinoma in Uganda.

571 Background: The effect of lifestyle factors, namely alcohol use, cigarette smoking, and other forms of tobacco use on hepatocellular carcinoma (HCC) remains unclear. We assessed the independent associations of lifestyle factors with HCC among individuals with and without viral hepatitis. Methods: In a hospital-based case-control study recruiting from Mulago and Lacor hospitals in Uganda from March 2015 to August 2021, HCC cases were confirmed by clinical and ultrasound criteria, with biochemical and pathology confirmation on a subset. Controls were frequency matched by age and sex and from the same hospitals. Demographic, clinical and lifestyle data were collected using standardized instruments. Alcohol content of local drinks was standardized, and intensity categorized as light, moderate, or heavy based on CDC definitions. We analyzed alcohol (use status (current, former, never), duration (years), frequency (drinks/week)), cigarette smoking (status (current, former, never), cumulative (pack‐years), duration (years), intensity (cigarettes/day), and time since cessation), other tobacco use (tobacco chewing and pipe-smoking), and viral hepatitis (HBV surface antigen (HBsAg) and HCV antibody (HCVAb)). We used logistic regression models (Stata 18.0) to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CIs) controlling for age, sex, family history of HCC, socioeconomic status, and Schistosomiasis (urine Circulating Cathodic Antigen (CCA)). Stratified analyses were performed separately by HBV and HCV status. Results: Among 596 HCC cases and 1,277 controls, the median age (IQR) was 43 (32-56) and 45 (31-54) years, 410 (68.8%) and 832 (65.0%) were males, 460 (24.6%) and 442 (23.7%) current or former alcohol users, 96 (5.1%) and 251 (13.4%) current or former cigarette smokers, and 177 (9.45%) and other tobacco users, respectively. Other tobacco users were more likely to be heavy (⩾10 pack-years) cigarette smokers (aOR=5.10; 95% CI: 2.41-10.79), heavy (>14 drinks/week for males and >7 drinks/week for females) alcohol drinkers (aOR=5.25; 95% CI: 2.84-9.68), farmers (aOR=1.61; 95% CI: 1.01-2.57) and lower socioeconomic status (aOR=3.23; 95% CI: 1.76-5.94). HCC risk was associated with HBV (aOR=18.66; 95% CI: 12.96-27.88), HCV (aOR= 4.03; 95% CI:2.31-7.02), and other tobacco use (aOR=1.86; 95%CI: 1.13-3.08). The observed HCC risk with other tobacco use, and the null associations with heavy alcohol use (aOR= 0.89; 95% CI: 0.60-1.31) and heavy cigarette smoking (aOR=0.74, 95% CI:0.34-1.60), were homogenous by HCV status (positive versus negative), and similarly by HBV status. Conclusions: Viral hepatitis (HBV and HCV), and lifestyle factors (tobacco chewing and pipe-smoking) were strongly associated with HCC. Further research should explore the role of tobacco chewing and pipe-smoking in HCC risk in Uganda and similar settings in Sub-Saharan Africa.

Serum uric acid is inversely associated with lung function in US adults

The relationship between serum uric acid and lung function has been controversial. This study aims to determine whether there is an independent relationship between serum uric acid and lung function in the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2012. Serum uric acid was considered the exposure variable, and lung function (FEV1 and FVC) was the outcome variable. Multivariable linear regression was conducted with adjustments for potential confounders. The total number of participants from NHANES (2007–2012) was 30,442, of which 7514 were included in our analysis after applying exclusion criteria. We observed that serum uric acid was negatively associated with FEV1 and FVC after adjusting for confounders (β for FEV1 [− 24.77 (− 36.11, − 13.43)] and FVC [− 32.93 (− 47.42, − 18.45)]). Similarly, serum uric acid showed a negative correlation with FEV1 and FVC after adjusting for confounding variables both in male and female populations. The relationship between serum uric acid and FEV1 and FVC remained consistent and robust in various subgroups within both male and female populations, including age, race, BMI, alcohol consumption, smoking status, and income-poverty ratio. Serum uric acid is negatively associated with FEV1 and FVC in the US general healthy population. This negative relationship is significant in both the male and female populations.

Profile of Prisoners with Latent Tuberculosis Infection (LTBI) In Correctional Institution Level IIA Kerobokan, Badung, Bali

Background: Prisoners have a high risk of being infected with latent Mycobacterium tuberculosis (LTBI). Crowded living conditions, poor ventilation, and inadequate facilities lead to a high risk of Mycobacterium tuberculosis (M.tb) transmission in correctional institutions ( CI ). TB disease causes a decline in the health of prisoners so it affects the quality of life while serving in prison. For this reason, it is necessary to conduct research on the profile of prisoners with LTBI. The results can later be used as a consideration for improving the health status of CI. This study was conducted in July 2023 in Level IIA prison, Kerobokan, Badung, Bali with variables in the form of characteristics of prisoners with positive LTBI status. Methods: Sample collection using cluster sampling by taking all prisoners in 1 block who have active TB patients. Prisoners underwent Tuberculin Skin Tests to determine LTBI status. Results: Prisoners with LTBI were found with the following characteristics: female gender (56.67%), aged <60 years (93.3%), smoking history (70%), length of stay in prison ≥12 months (73.3%), drug users (36.67%), history of alcohol consumption (50%). Conclusion: This study provides an overview of the profile of prisoners with LTBI in level IIA Kerobokan prison, Badung, Bali. Latent TB infection was more prevalent among female prisoners with female gender, young age, active smokers, drug and alcohol consumption, and length of stay in prison more than 12 months.

Alcohol-induced hormonal and metabolic alterations in plasma and erythrocytes—a gender-based study

Purpose This study aimed to understand the gender-specific alcohol-induced biochemical changes and TBARS association with the endocrine system. Methods Human male and female subjects ranging from 35 ± 10 years old with an 8-10-year drinking history were included in the study. Results The results demonstrated that testosterone levels were lower in male alcoholics and higher in female alcoholics, as well as higher estrogen and cortisol levels in both genders. In addition, we found lower T3, T4, and thyroid-stimulating hormone (TSH) levels in alcoholics of both sexes. Furthermore, plasma TBARS, protein carbonyls, nitrite, and nitrate levels increased significantly with concomitant decrease in reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) activities in both male and female alcoholics. Furthermore, erythrocyte lysate nitrite and nitrate levels membrane total cholesterol, phospholipid and cholesterol/phospholipid (C/P) ratio with lower total membrane proteins in both genders of alcoholics. SDS-PAGE analysis of erythrocyte membrane proteins revealed increased density of band 3, protein 4.1, 4.2, 4.9 and glycophorins, whereas decreases in spectrin (α and β) were observed in both genders of alcoholics. Besides, alcoholics of both sexes had a lower ability to resist osmotic hemolysis. Plasma TBARS was negatively correlated with testosterone, TSH, T3 and T4 in male alcoholics, moreover, estradiol and cortisol were positively correlated in males and females respectively. Conclusion Female alcoholics may be more susceptible to osmotic hemolysis due to increased erythrocyte membrane lipid peroxidation with decreased antioxidant status, which results in an altered membrane C/P ratio and membrane protein composition.

Sex, executive function, and prospective memory regulate the chain-mediation pathway of alcohol use and impulsivity.

Evidence from previous studies indicates that impulsive behaviors are closely linked to alcohol use and misuse and that female drinkers are more impulsive than male drinkers. However, studies investigating the psychological mechanisms of alcohol use and impulsivity based on sex differences are relatively limited. This cross-sectional study comprised 713 residents from 16 cities in Anhui Province, China. Each subject was evaluated for self-reporting measures using several questionnaires, including the general information questionnaire, the Alcohol Use Disorders Identification Test (AUDIT), the Prospective and Retrospective Memory Questionnaire (PRM), the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A), and the Barratt Impulsiveness Scale-11 (BIS-11). Executive function and prospective memory may serve as intermediary links between alcohol use and impulsivity. Although the female alcohol usage level was significantly lower than that of males, the female drinkers had more severe executive dysfunction, prospective memory impairment, and impulsivity than male drinkers. Sex moderated the relationship between alcohol use and impulsivity. Furthermore, the indirect effect of executive function, and prospective memory between AUDIT and BIS was more significant in males than in females. Alcohol consumption may be associated with impulsivity formation through executive dysfunction and PM impairment, implying that impulsivity in those with AUD or at risk for AUD might be treated by improving EF and PM. Alcohol use may cause more severe executive dysfunction, PM impairment, and impulsive behavior in females than in males, and impulsive behavior in women with AUD was more likely to be due to the direct effects of alcohol consumption, while impulsive behavior in men with AUD was more likely to be due to the indirect effects of executive dysfunction and PM impairment. These findings provide both clinical and theoretical foundations for addressing issues related to alcohol use.

Verification of a Three-day Hospitalization Protocol for Chronic Subdural Hematoma Surgery.

Chronic subdural hematoma (CSH) is predominantly a disease of the elderly. Aging societies in advanced countries are seeing the number of CSH cases increasing. We applied a three-day hospitalization protocol for CSH surgery to reduce healthcare costs and more efficiently manage hospital beds. We investigated the clinical factors that influenced prolonged hospitalization. From January 2015 to December 2020, we performed irrigation, evacuation, and drainage of CSH cases in 221 consecutive patients. The χ2 test and logistic regression analysis were conducted to detect clinical factors influencing prolonged hospitalization. A p-value below 0.05 was considered statistically significant. Applying a three-day hospitalization protocol showed no adverse outcomes. Fifty-two (24%) of 221 patients experienced prolonged hospitalization. The χ2 test showed that female gender, atrial fibrillation, alcohol abuse, preoperative consciousness level, verbal function disturbance, and perioperative activities of daily living were significantly related to prolonged hospitalization. Female gender, atrial fibrillation, and alcohol abuse were significant factors in the logistic regression analysis. A three-day hospitalization protocol for CSH is suitable for patient care; however, particular attention needs to be focused on the female gender, atrial fibrillation, and alcohol abuse, all three of which prolong hospitalization.

Aversion-associated drug and alcohol seeking in females

Compulsive drug intake is characterized by the continuation of use regardless of negative consequences. This is modeled preclinically using procedures where a negative stimulus is delivered contingently with consumption of the reinforcer. In humans, women and men exhibit different drug taking behavior as it pertains to overall use, withdrawal symptoms, and rate of dependence. In substance use research, females have often been excluded from many studies due to concerns that circulating sex hormones may affect drug seeking behavior. However, the more recent inclusion of females in preclinical studies has identified interesting sex differences in aversion-resistant intake of drugs and alcohol. This review will serve to summarize key findings in aversion-related intake of alcohol, psychostimulants, and opioids in females by examining studies that have included female subjects. Further discussion will examine the effect of intake model, neuroanatomical pathways, and sex hormones in the expression of aversion-resistant drug and alcohol consumption.

Oxytocin Attenuates Yohimbine-Induced Reinstatement of Alcohol-Seeking in Female Rats via the Central Amygdala.

Alcohol use disorder is a significant public health concern, further exacerbated by an increased risk of relapse due to stress. In addition, factors such as biological sex may contribute to the progression of addiction, as females are especially susceptible to stress-induced relapse. While there have been many studies surrounding potential pharmacological interventions for male stress-induced ethanol reinstatement, research regarding females is scarce. Recently, the neuropeptide oxytocin has gained interest as a possible pharmacological intervention for relapse. The present study examines how oxytocin affects yohimbine-induced reinstatement of ethanol-seeking in female rats using a self-administration paradigm. Adult female rats were trained to press a lever to access ethanol in daily self-administration sessions. Rats then underwent extinction training before a yohimbine-induced reinstatement test. Rats administered with yohimbine demonstrated significantly higher lever response indicating a reinstatement of ethanol-seeking behavior. Oxytocin administration, both systemically and directly into the central amygdala, attenuated the effect of yohimbine-induced reinstatement of ethanol-seeking behavior. The findings from this study establish that oxytocin is effective at attenuating alcohol-relapse behavior mediated by the pharmacological stressor yohimbine and that this effect is modulated by the central amygdala in females. This provides valuable insight regarding oxytocin's potential therapeutic effect in female stress-induced alcohol relapse.

Psychological benefits of the COVID‐19 vaccination: A Bangladeshi comparative study

AbstractBackground and AimsDespite evidence that COVID‐19 vaccination can strengthen mental health, there is limited evidence about this in Bangladesh. Thus, this comparative study assessed the prevalence and factors associated with mental health problems between vaccine receivers and nonreceivers.MethodsUsing a snowball sampling technique, a web‐based cross‐sectional study was conducted among a total of 459 participants. The survey questionnaire included sociodemographic information, the Patient Health Questionnaire (PHQ—9), the Generalized Anxiety Disorder (GAD—7), and the Trauma Screening Questionnaire (TSQ—10).ResultsThe study found that mental health problems were nonsignificantly prevalent in the vaccine nonreceivers than those who received it (i.e., 24.79% vs. 20.60% for depression, 21.20% vs. 16.60% for anxiety, and 15.30% vs. 12.60% for posttraumatic stress disorder). Female gender, chronic condition, smoking status, and alcohol consumption were the risk factors for mental health problems.ConclusionThis study's findings suggest that the COVID‐19 vaccination necessarily improves mental health outcomes. However, the study had limitations in terms of its design and sampling technique, and further research is needed to establish a cause‐effect relationship between vaccination and mental health problems.

The socioeconomic profile of alcohol use in Europe: findings from 33 European countries

Background: Alcohol’s detrimental health effects do not affect everyone equally but accumulate in people with low socioeconomic status (SES). Using data from the 2021 Standard European Alcohol Survey, we explore gender- and SES-specific consumption patterns, and COVID-19 related changes in consumption across Europe.
 Methods: Cross-sectional population-based survey data from 54,354 adults from 33 European countries plus Spain-Catalonia were analysed. Five alcohol indicators were of interest: prevalence of past-year alcohol use; and, among past-year alcohol users, prevalence of monthly/more frequent risky-single-occasion-drinking (monthly+ RSOD); prevalence of high-risk alcohol use (40+/60+ grams pure alcohol daily for women/men); mean daily grams of pure alcohol consumed; and self-reported consumption changes during COVID-19. Alcohol indicators were age-standardised and decomposed by gender and SES (education attainment), and analysed using regression models with location-specific random intercepts.
 Results: Across jurisdictions, past-year alcohol use, monthly+ RSOD, and high-risk drinking were all commonly reported, with distinct gender-specific socioeconomic profiles. While high-SES men and women were generally more likely to report past-year alcohol use, monthly+ RSOD and high-risk drinking were more prevalent among currently drinking low/mid-SES compared to high-SES men. No such SES differences in risky drinking were observed among women, however, female alcohol users with high SES reported higher mean daily drinking levels. High-SES women but not men were more likely to both increase and decrease their drinking during COVID-19 compared to their low/mid-SES counterparts.
 Conclusion: High consumption levels and distinct socioeconomic profiles among men and women highlight the need for effective alcohol policies to reduce health inequalities in Europe.
