Objectives

Thiamine is often prescribed for thiamine deficiency during hospitalization despite the lack of US-based clinical guidelines. This study aims to evaluate thiamine prescribing patterns and key characteristics associated with the deficiency to address gaps in care.

Methods

Data were obtained from electronic health records of hospitalized patients between September 1, 2021, and March 30, 2022. Alcohol use disorder (AUD) was defined by a positive Clinical Institute Withdrawal Assessment score or a positive serum alcohol level upon admission. Geriatric patients were defined as age ≥65. Cohort 1 was defined as: AUD, albumin <4 g/L, INR >1.5, and total bilirubin >3 mg/dL. Cohort 2 was defined as: age >65, albumin <4 g/L, hemoglobin <15 g/dL, and folate <4 ng/mL. A multivariable LASSO regression model was used to identify characteristics associated with higher thiamine dosing (>100 mg/day).

Results

Among 780 patients, 520 (66.7%) were identified as AUD, of which 265 (50.1%) were between the ages of 45–64 years. The AUD cohort was significantly different (p < 0.05) in the mean serum albumin 4.16 g/L (IQR: 3.8–4.5), AST 73.55 U/L (23.75–82.00), ALT 52.57 U/L (17.00–57.00), total bilirubin 0.98 (0.3–1.0), and INR 1.1 (0.99–1.12), compared to non-AUD patients with a mean serum albumin 3.75 g/L (3.3–4.2), AST 35.07 U/L (11.00–42.00), ALT 32.77 U/L (5.00–34.00), total bilirubin 0.89 (0.2–0.9), and INR 1.21 (1.0–1.22). In the geriatric cohort, 136 patients (17%) had a mean serum albumin 3.77 g/L (3.4–4.2), AST 38.66 U/L (14.0–41.0), ALT 29.36 U/L (9.0–37.0), total bilirubin 0.62 mg/dL (0.30–0.90), and direct bilirubin 0.12 mg/dL (0.00–0.20), compared to the non-geriatric cohort with a mean serum albumin 4.10 g/L (3.8–4.40), AST 66.44 U/L (21.0–75.0), ALT 50.03 U/L (16.00–53.75), total bilirubin 1.02 mg/dL (0.30–1.00), and direct bilirubin 0.31 mg/dL (0.00–0.20). In cohort 1, 40.6% patients were between 51 and 64 years old, (66.5%) male, and had a BMI <25 (36.4%). In cohort 2, 52.6% were between 65 and 70 years old, (57.9%) male, and had a BMI <25 (57.9%). Cohort 1 were prescribed a dose of 100 mg (47.7 %), oral (63.5%), intramuscular (18.2%), daily (58.9%), one-day duration (49.4%) most frequently. Cohort 2 were prescribed a dose of 100 mg (56.0%), oral (77.2%), daily (77.2%), one-day duration (29.8%) most frequently. The AUD was significantly associated with having a higher dosage (e.g., >100 mg) of thiamine prescribed per day OR 1.62 (1.11–2.37) (p < 0.01).

Conclusions

This study confirms that thiamine prescribing patterns vary during hospitalization and suggest specific laboratory findings may aid in identifying cohorts associated with the deficiency.

Introduction

Concern about adverse effects from phenobarbital limits its use in treating alcohol withdrawal syndrome (AWS) on general medical wards. Benzodiazepines are the recommended treatment for inpatient management of AWS, yet a subset of patients have an inadequate response or experience complications of AWS despite treatment with benzodiazepines. Data supporting an alternative treatment are needed. We set out to estimate the rate of serious adverse events (SAEs) of phenobarbital treatment for AWS on general medical wards.

Methods

Retrospective cohort study of all general medical ward patients hospitalized at a single tertiary urban VA Medical Center from October 2018–May 2021 who received phenobarbital for treatment of AWS. Primary outcomes were SAEs attributed to phenobarbital and treatment failure. SAEs were defined as ICU transfer or intubation for over-sedation, pneumonia, and death. Treatment failure was defined as progression of withdrawal resulting in seizure, ICU transfer, behavioral emergencies, or death.

Results

During the study period, phenobarbital was administered in 29% (244) of all AWS hospitalizations. Among them, 93% had a history of AWS hospitalization and 68% had a history of complicated AWS. Fifty-three percent of patients met criteria for moderate, severe, or complicated withdrawal prior to phenobarbital initiation. The mean cumulative dose of phenobarbital per patient was 966.5 mg (13.6 mg/kg). SAEs occurred in 1 of 244 hospitalizations (0.4%): there were no intubations, ICU transfers for oversedation, or deaths due to phenobarbital or AWS. One case of pneumonia was possibly attributable to phenobarbital. Treatment failures (6 ICU transfers, 9 behavioral emergencies) were identified during 12 of 244 hospitalizations (4.9%).

Conclusions

SAEs and treatment failures were infrequent among 148 patients treated with phenobarbital across 244 hospitalizations with a mean cumulative dose of 966.5 mg per patient. Our findings suggest that phenobarbital is a safe alternative treatment of AWS in general medical ward patients.

Background

The rising elderly population and the concomitant increase in alcohol consumption can result in a ground level fall (GLF). The purpose of this study is to evaluate the in-hospital mortality, hospital length of stay, and discharge disposition of elderly patients who sustained a ground level fall (GLF) and tested positive for an elevated blood alcohol concentration (BAC).

Methods

The data of patients who were 65 years and older, had an injury after a GLF, and tested for BAC were accessed from the American College of Surgeon – Trauma Quality Improvement Program (ACS-TQIP) from the calendar years of 2011–2016. Patients’ demography, injury, comorbidities, and outcomes were compared between the groups who tested positive (>0.08 g/dL) and negative (0 mg/dL) for BAC. Univariate, followed by matched analyses were performed. All p values are two-sided, and a p value < 0.05 is considered statistically significant.

Results

Out of 20,163 patients who satisfied the inclusion criteria, 2398 patients (∼12%) tested positive for an elevated BAC. There were significant differences found between the two groups, BAC-positive vs. BAC-negative, in univariate analysis for age and sex with p values < 0.001. Propensity score matching balanced demographic characteristics; however, differences remained in certain comorbidities. Exact matching balanced patient demography, injury, and comorbidities. The paired-matched analysis showed no significant differences between the two groups for in-hospital mortality (2.1% vs. 2.1%, p = 1) and median hospital length of stay (5[4–5] vs. 5[5–5], p = 0.307). A higher proportion of patients in the BAC group suffered from alcohol withdrawal syndrome (AWS) and deep vein thrombosis (DVT) complications (9.5% vs. 1.4%, p < 0.001 and 1.5% vs. 0.5%, p = 0.018) compared to BAC-negative patients. A slightly higher percentage of patients in the BAC-positive group were discharged home without any additional services (39.6% vs. 36.9%, p = 0.009).

Conclusion

Of the elderly patients who sustained a GLF and tested for BAC, approximately 12% tested positive for BAC. The overall in-hospital mortality was 2.1%. The BAC-positive group suffered from higher complications of AWS and DVT, and more than 60% of patients required additional services at the time of discharge.

Problematic alcohol use and binge eating frequently co-occur. High levels of negative affect, negative urgency, and/or shame may increase the likelihood that problematic alcohol use and binge eating co-occur over time.

Objective

Examine 1) the temporal relationship between problematic alcohol use and binge eating among college women, who are at high risk for both, and 2) the additive and moderating effects of shared, emotion-based risk factors in models involving both problematic alcohol use and binge eating.

Method

In n = 302 college women assessed at two time points across 8 months, we used hierarchical linear regression to invstigate our objectives.

Results

Baseline problematic alcohol use and baseline shame independently predicted increases in follow-up binge eating, controlling for baseline binge eating. In addition, the interaction between problematic alcohol use and shame accounted for further variance in subsequent binge eating (the influence of baseline problematic alcohol use on follow-up binge eating was stronger at higher levels of baseline shame). The reciprocal relationship was not significant: baseline binge eating did not predict follow-up problematic alcohol use independently or in conjunction with risk factors. Neither negative affect nor negative urgency showed predictive effects beyond prior behavior and shame. Results support 1) problematic alcohol use as a prospective risk factor for binge eating, 2) shame as an additive predictor of binge eating, and 3) shame as a positive moderator of binge eating prediction from problem drinking.

Conclusion

Addressing shame and problematic alcohol use may be warranted in binge eating interventions for college women.

Accumulating evidence suggests that particular parenting behaviors (e.g., elevated psychological control) may increase risk for both problematic social anxiety and alcohol use among youth; however, no work has yet examined these factors together in a single model. Building developmentally sensitive models of problematic alcohol use trajectories is key to developing effective prevention and intervention strategies. The present study includes 94 adolescents (ages 14–17 years; 53.3% girls; 89.2% White) entering a treatment facility for a variety of internalizing and externalizing forms of psychological distress. Levels of perceived parental psychological control, social anxiety, and coping-related drinking motives were assessed. Higher levels of perceived psychological control were associated with a greater endorsement of coping-related drinking motives; however, a significant proportion of that association was accounted for by elevated social anxiety symptoms. These data extend the existing literature and lay groundwork for more sophisticated experimental and longitudinal designs to corroborate the findings. Moreover, personality-targeted drinking interventions for adolescents may benefit from identifying elevated perceived psychological control as a developmentally relevant risk factor for social anxiety and problematic drinking motives and administering relevant interventions (e.g., personality-targeted coping skills training, parent-involved care) before drinking patterns are established.

In human adolescents, females often report drinking for coping reasons to avoid negative affective states. We have shown previously that adolescent female rats with elevated levels of anxiety-like behavior under social test circumstances, indexed via low social preference, are sensitive to anxiolytic effects of ethanol given intraperitoneally (i.p.) in a low-to-moderate dose range. This study was designed to test the hypothesis that patterns of neuronal activation across brain regions implicated in social activity and social preference (used as an index of low versus high anxiety-like social responding) would be affected by acute ethanol differently in adolescent females with high and low social preference, with initial levels of social preference also predicting ethanol-induced changes in social behavior. Adolescent female Fos-LacZ rats were given social interaction tests on postnatal day (P)33 for determination of baseline levels of responding to an unfamiliar social partner and on P35 following administration of 0 or 0.75 g/kg ethanol. Brain tissue was collected, and expression of β-galactoside (β-gal) was used as an index of neuronal activation. Baseline levels of social preference did not predict social responsiveness to an acute ethanol challenge, whereas significant decreases in this social measure that reflects anxiety-like behavioral alterations were evident in adolescent females challenged with ethanol relative to saline-injected controls, suggesting high sensitivity to the anxiogenic effects of ethanol. Ethanol precipitated negative relationships between social preference and prefrontal cortical activation, decreased neuronal activation of the anterior cingulate cortex, but substantially increased β-gal expression in the central amygdala. These results suggest high sensitivity of the prefrontal cortical regions and central amygdala to ethanol-induced alterations in adolescent Fos-LacZ females and provide a background for further phenotyping of neurons activated by ethanol under social test circumstances.
