RESUMO

BACKGROUND: Alcohol use disorder is associated with a variety of complications, including alcohol withdrawal syndrome (AWS), which may occur in those who decrease or stop alcohol consumption suddenly. AWS is associated with a range of signs and symptoms, which are most commonly treated with GABAergic medications. CLINICAL QUESTION: Is phenobarbital an effective treatment for AWS? EVIDENCE REVIEW: Studies retrieved included two prospective, randomized, double-blind studies and three systematic reviews. These studies provided estimates of the effectiveness and safety of phenobarbital for treatment of AWS. CONCLUSIONS: Based on the available literature, phenobarbital is reasonable to consider for treatment of AWS. Clinicians must consider the individual patient, clinical situation, and comorbidities when selecting a medication for treatment of AWS.

RESUMO

BACKGROUND: Approximately 1 in 6 cannabis users develop a cannabis use disorder (CUD) and the odds increase to 1 in 2 for daily users. OBJECTIVE: The Dual use of Cannabis and Tobacco Monitoreing through a Gamified Web app (DuCATA_GAM-CaT) project aims to identify cannabis-tobacco patterns of use and withdrawal symptoms among individuals with CUD who are attending substance abuse programs. METHODS: The project uses a mixed methods approach consisting of 3 studies. First, a participatory qualitative study involves focus groups comprising individuals with CUD, clinicians, project researchers, and an expert gamification company to co-design a gamified web app. Second, a longitudinal prospective study to follow up individuals over 6 weeks with CUD attending substance abuse programs . Participants report their cannabis-tobacco usage patterns, type and frequency of tobacco use, nicotine dependence, withdrawal symptoms, psychoemotional factors, and motivation to quit both substances. Predictive analysis techniques are used to analyze clinical, demographic, psychological, and environmental data to predict the probability of achieving abstinence. Third, homogeneous focus groups to explore participants' experiences during their CUD treatment. RESULTS: By June 2024, the project had completed the first study, defining eligible cannabis user profiles, developed the initial web app prototype, and initiated recruitment across 10 centers, with 74 participants enrolled, aiming to reach 150 participants in total. CONCLUSIONS: All participants are required to provide informed consent, and their information is kept confidential and anonymized following confidentiality rules. The research team is committed to disseminating the results obtained to professional and patient groups, as well as informing public health agents, to positively influence political and social decision makers and design programmers. Additionally, we aim to prioritize the publication of the results in high-impact journals specialized in drug abuse, public health, and health care services research.

RESUMO

BACKGROUND: Analgosedation is standard practice to ensure comfort and safety of critically ill children in paediatric intensive care units (PICUs). However, a significant number of children develop iatrogenic withdrawal syndrome or delirium with these drugs. The European Society of Paediatric and Neonatal Intensive Care published a position statement in 2016, but how successfully its recommendations have been implemented is unknown. OBJECTIVES: Following were the objectives of this study: (i) to describe assessment practices (prevalence, measurement instruments, and frequency) for pain, sedation, iatrogenic withdrawal syndrome and delirium; (ii) to assess how practices meet the position statement; and (iii) to identify organisational factors associated with the use of recommendations for pain and sedation assessment. METHOD: A secondary analysis of prospectively collected data from the multicentre prevalence study (European Prevalence of Acute Rehab for Kids in the PICU) conducted in 38 PICUs, across 15 European countries in 2018. Data from 453 children were analysed. RESULTS: Of the 38 PICUs, 97% assessed pain, 89% sedation, 82% withdrawal, and 42% delirium. These four symptoms were mainly assessed and documented by the Face, Legs, Activity, Cry, Consolability scale (39%) and Numerical Rating Scale (24%) every 8, 4, or 2 h for pain; the COMFORT-B (45%) and COMFORT (24%) scales every 8 or 2 h for sedation; the Sophia Observation withdrawal Scale (37%) and Withdrawal Assessment Tool-1 (32%) scales every 8 or 4 h for withdrawal and the Cornell Assessment Pediatric-Delirium (18%) and Sophia Observation Withdrawal Symptoms-Pediatric Delirium (16%) scales every 12 or 8 h for delirium. Concordance with the position statement recommendations was low to moderate (13-69%). Adherence to recommendations were influenced by the variables of nurse-to-patient ratio, type of hospital, and the number of PICU beds. CONCLUSION: Based on prospectively collected data, there was variability in pain and sedation assessment practices and a lack of adherence with recommendations in the EU, particularly for delirium. These findings highlight the need for more proactive dissemination, and investigation of barriers and implementation strategies to improve evidence-based assessment practices.

RESUMO

Background: Neonatal Opioid Withdrawal Syndrome (NOWS) is a consequence of in-utero exposure to prenatal maternal opioids, resulting in the manifestation of symptoms like irritability, feeding problems, tremors, and withdrawal signs. Opioid use disorder (OUD) during pregnancy can profoundly impact both mother and fetus, disrupting fetal brain neurotransmission and potentially leading to long-term neurological, behavioral, and vision issues, and increased infant mortality. Drug resistance complicates OUD and NOWS treatment, with protein kinase regulation of drug transporters not fully understood. Methods: DNA methylation levels of ATP-binding cassette (ABC) and solute carrier (SLC) drug transporters, along with protein kinase C (PKC) genes, were assessed in 96 placental samples using the Illumina Infinium MethylationEPIC array (850K). Samples were collected from three distinct groups: 32 mothers with infants prenatally exposed to opioids who needed pharmacological intervention for NOWS, 32 mothers with prenatally opioid-exposed infants who did not necessitate NOWS treatment, and 32 mothers who were not exposed to opioids during pregnancy. Results: We identified 69 significantly differentially methylated SLCs, with 24 hypermethylated and 34 hypomethylated, and 11 exhibiting both types of methylation changes including SLC13A3, SLC15A2, SLC16A11, SLC16A3, SLC19A2, and SLC26A1. We identified methylation changes in 11 ABC drug transporters (ABCA1, ABCA12, ABCA2, ABCB10, ABCB5, ABCC12, ABCC2, ABCC9, ABCE1, ABCC7, ABCB3): 3 showed hypermethylation, 3 hypomethylation, and 5 exhibited both. Additionally, 7 PKC family genes (PRKCQ, PRKAA1, PRKCA, PRKCB, PRKCH, PRKCI, and PRKCZ) showed methylation changes. These genes are associated with 13 pathways involved in NOWS, including ABC transporters, bile secretion, pancreatic secretion, insulin resistance, glutamatergic synapse, and gastric acid secretion. Conclusion: We report epigenetic changes in PKC-related regulation of drug transporters, which could improve our understanding of clinical outcomes like drug resistance, pharmacokinetics, drug-drug interactions, and drug toxicity, leading to maternal relapse and severe NOWS. Novel drugs targeting PKC pathways and transporters may improve treatment outcomes for OUD in pregnancy and NOWS.

RESUMO

Background: Understanding the interplay between psychopathology of alcohol withdrawal syndrome (AWS) in alcohol use disorder (AUD) patients may improve the effectiveness of relapse interventions for AUD. Network theory of mental disorders assumes that mental disorders persist not of a common functional disorder, but from a sustained feedback loop between symptoms, thereby explaining the persistence of AWS and the high relapse rate of AUD. The current study aims to establish a network of AWS, identify its core symptoms and find the bridges between the symptoms which are intervention target to relieve the AWS and break the self-maintaining cycle of AUD. Methods: Graphical lasso network were constructed using psychological symptoms of 553 AUD patients. Global network structure, centrality indices, cluster coefficient, and bridge symptom were used to identify the core symptoms of the AWS network and the transmission pathways between different symptom clusters. Results: The results revealed that: (1) AWS constitutes a stable symptom network with a stability coefficient (CS) of 0.21-0.75. (2) Anger (Strength = 1.52) and hostility (Strength = 0.84) emerged as the core symptom in the AWS network with the highest centrality and low clustering coefficient. (3) Hostility mediates aggression and anxiety; anger mediates aggression and impulsivity in AWS network respectively. Conclusions: Anger and hostility may be considered the best intervention targets for researching and treating AWS. Hostility and anxiety, anger and impulsiveness are independent but related dimensions, suggesting that different neurobiological bases may be involved in withdrawal symptoms, which play a similar role in withdrawal syndrome.

RESUMO

Background: The rising incidence of drug abuse among pregnant women has rendered neonatal opioid withdrawal syndrome a significant global health concern. Methods: Databases including PubMed, Web of Science, the Cochrane Library, Embase, Elton B. Stephens. Company (EBSCO), China National Knowledge Infrastructure (CNKI), and Wanfang were searched for comparative studies of the Eat, Sleep, Console model vs. traditional assessment tools for neonatal opioid withdrawal syndrome. Two reviewers conducted literature searches, screened according to the inclusion criteria, extracted data, and independently verified accuracy. All meta-analyses were conducted using Review Manager Version 5.4. Results: In total, 18 studies involving 4,639 neonates were included in the meta-analysis. The Eat, Sleep, Console model demonstrated superior outcomes in assessing neonatal opioid withdrawal syndrome, significantly reducing the need for pharmacological treatment [risk ratio = 0.44, 95% confidence interval (CI) = 0.34-0.56, P < 0.001], decreasing the length of hospital stay [standard mean difference (SMD) = -2.10, 95% CI = -3.43 to -0.78, P = 0.002], and shortening the duration of opioid treatment (SMD = -1.33, 95% CI = -2.22 to -0.45, P = 0.003) compared to the Finnegan Neonatal Abstinence Scoring System. Conclusions: The Eat, Sleep, Console model is more effective than the Finnegan Neonatal Abstinence Scoring System in improving the assessment and management of neonatal opioid withdrawal syndrome.

RESUMO

Aim: To assess inpatient growth parameter trajectories and to identify the type of opioid exposure and treatment characteristics influencing growth parameters of infants admitted to the newborn intensive care unit (NICU) for pharmacological treatment of neonatal opioid withdrawal syndrome (NOWS). Methods: Charts of term infants with NOWS admitted to NICU from 2012 to 2019, who received pharmacologic treatment, were reviewed. Intake (volume: mL/kg/day; calorie: kcal/kg/day) and growth parameter trajectories (weight, head circumference, and length) were analyzed based on the type of prenatal opioid exposure (short-acting opioids (SAOs), long-acting opioids (LAOs), and polysubstance), pharmacologic treatment, and sex. Growth measurement patterns over time were compared between groups using longitudinal mixed-effects models. Results: One hundred nineteen infants were included in the study with median birth weight Z-score of -0.19 at birth and decreased to a median of -0.72 at discharge. Exposure to SAO was associated with an increase in Z-scores nearing discharge across all growth parameters (Z-score for weight p = 0.03). Polysubstance exposure was associated with a decrease in Z-scores for length and head circumference throughout hospitalization. Infants with adjunct clonidine treatment had an increase in Z-score for weight trends. Male infants had a decrease in Z-scores for weight (male -0.96, female -0.59, interaction p = 0.06) and length (male -1.17, female -0.57, interaction p = 0.003) at Day 28. Despite the difference in growth trajectories, intake in terms of amount (mL/kg/day) and calorie intake (kcal/kg/day) was similar based on prenatal exposure, treatment, and sex. Conclusion: Infants with NOWS requiring pharmacologic treatment have a decrease in Z-scores for weight, length, and head circumference at birth and at hospital discharge. Infants with prenatal polysubstance exposure were at particular risk for poorer inpatient growth relative to infants exposed to SAO and LAO, indicated by lower Z-scores for length and occipital frontal circumference (OFC).

RESUMO

The present real-world analysis aimed to evaluate and describe the use of gamma-hydroxybutyric acid (GHB) for alcohol withdrawal syndrome (AWS) in hospitalized patients with diagnosis of liver cirrhosis. An 11-year observational retrospective study on patients affected by liver cirrhosis and alcohol use disorder (AUD) was performed using data from the Medical Toxicology Unit of Careggi University Hospital in Florence (Italy). A multivariate logistic regression was performed to estimate the probability of having a CIWA-Ar Max 3-4 during hospitalization, an AWS length > 36 h, a hospitalization > 9 days, and the probability of developing drowsiness. A total of 166 AUD patients were included, of these 77 received GHB (70.13% within the first day of hospitalization) and 89 were treated without GHB. The majority were ≥ 40 years of age (87.35%) and males (80.12%). GHB patients were more likely to have a CIWA-Ar Max 3-4 during hospitalization (OR 3.76 [CI 95% 1.02-13.85]), and a longer hospitalization (OR 3.08 [95% CI 1.23-7.71]). Early GHB administration decreased the probability of CIWA-Ar Max worsening (OR 0.06 [95% CI 0.01-0.49]). GHB dose ≥ 100 mg/kg was not associated with the occurrence of drowsiness. Patients exposed to other sedative agents were more likely to experience drowsiness (OR 7.22 [95% CI 1.46-35.61]). The present real-world analysis underlines that GHB could be a valuable and safe option for the management of AWS in AUD patients affected by liver cirrhosis, also when administered early and even at higher than recommended dosages.

RESUMO

The onset of the disease as a morphine addiction is associated with the appearance in the patient's body of antibodies directed against opiate receptors (ORs). Once anti-opiate receptor antibodies (anti-OR antibodies) appear in the blood they will tend to bind to ORs. Such binding will cause blocking of physiological functions of OR. The blockage is felt by a morphine addict as withdrawal syndrome. To get rid of this harmful condition, the addict increases the dose of morphine taken. This is where tolerance manifests itself. The drug addict is forced to increase the dose of morphine from time to time because of the body responds by producing the more and more anti-OR antibodies. The immunological nature of morphine addiction is the reason for lifelong changes in the body's reactivity to the drug. An addict can be cured if he gets rid of B- and T-memory cells, which specifically react to ORs.

RESUMO

PURPOSE: Opioid medications are necessary in the treatment of critically ill infants; however. prolonged use may lead to withdrawal syndrome. The purpose of this study was to assess feasibility of delivering an acupressure protocol for the treatment of iatrogenic withdrawal in a pediatric cardiac intensive care unit as well as impact and acceptance of acupressure as an adjunct treatment. DESIGN: Randomized pilot feasibility trial. METHODS: Acupressure stickers were applied and rotated to one ear every 1-3 days until withdrawal symptoms improved. RESULTS: There were no serious adverse events, with only one reported incident of skin irritation. Recruiting benchmarks were exceeded. Weaning phases were significantly shorter in the acupressure group (medians 6.0 vs 22.0 respectively, p = .025, d = 0.90) and the control group used skin-to-skin contact as a comfort measure significantly more than the acupressure group (42.9% vs 6.3%, p = .18). Acupressure was accepted by parents, with an overall 96.2% rating their experience as positive, as measured by the Parent Client Satisfaction Questionnaire. The majority of health care providers (n = 19) were supportive, with 71.9% agreeing or completely agreeing acupressure is an acceptable adjunct for the treatment of withdrawal symptoms; 26.8% were neutral, as measured by the Acceptability of Intervention Measure, Intervention Appropriateness Measure, and Feasibility of Intervention Measure. CONCLUSIONS: Acupressure was found to be safe, feasible, and accepted by health care providers in a pediatric cardiac intensive care setting. CLINICAL IMPLICATIONS: These findings support future research with larger sample sizes to improve clinical treatment of infants physically dependent on sedative medications.

RESUMO

The akinetic crisis is a well-known, rare, potentially life-threatening condition in Parkinson's disease with subacute worsening of akinesia, rigidity, fever, impaired consciousness, accompanying vegetative symptoms and transient dopa-resistance. The akinetic crisis was historically supposed to be a "withdrawal syndrome" in the sense of discontinuation of dopaminergic medication. Recently, other "withdrawal syndromes" as the specific "dopamine agonist withdrawal syndrome" or "deep brain stimulation withdrawal syndrome" have been described as emergency situations with specific subacute symptom constellations. All three conditions require immediate start of the adequate therapy to improve the prognosis. Here, the diagnostic criteria and treatment options of these three acute, severely disabling syndromes will be reported along the current guidelines of the German Parkinson Guideline Group.

RESUMO

INTRODUCTION: Opioid use during pregnancy and subsequent neonatal opioid withdrawal syndrome (NOWS) have been associated with poor developmental outcomes including cognitive functioning. Less is known about the underlying molecular effects of prenatal opioid exposure and subsequent withdrawal; however, given the recent increase in NOWS cases, there is a pressing need to better understand these effects, which may partially explain cognitive deficits that have been observed in both preclinical NOWS models and patients with NOWS. This study evaluated the effects of prenatal heroin exposure and subsequent precipitated withdrawal symptoms on microglial reactivity in the nucleus accumbens (NAc), dorsal hippocampus (HC), and ventral tegmental area (VTA) in rat neonates, as well as cognitive functioning at three developmental time points using the Morris Water Maze (MWM) task. METHODS: Heroin or saline (2 mg/kg) was randomly assigned and administered to six pregnant Sprague Dawley rat dams via osmotic minipump. A total of 63 rat neonates underwent naloxone-precipitated (5 mg/kg, subcutaneous injection) withdrawal testing at postnatal day 10 (PN10). Following withdrawal testing, neonates were randomly assigned to undergo perfusion and subsequent immunohistochemistry experiments to fluoresce Iba-1 for microglia detection, or to undergo the MWM task at three separate developmental time points (PN21-23; PN37; PN60) for cognitive testing. RESULTS: Results suggest that in-utero heroin exposure led to an increase in ultrasonic vocalizations during naloxone-precipitated withdrawal; a sensitive index of withdrawal in rat neonates. Additional results suggest increased microglial reactivity in the HC and VTA, but not the NAc, as well as reduced performance during the MWM in the group exposed to heroin in-utero. DISCUSSION: Together, these data suggest that in-utero opioid exposure is associated with microglial reactivity in brain regions associated with learning and memory, and may be associated with later cognitive deficits. Further research is needed to characterize these findings, which may inform future therapeutic strategies for this vulnerable population.

RESUMO

OBJECTIVE: To increase nurses' awareness and use of a human milk feeding (HMF) and opioid use disorder (OUD) standardized care pathway to improve rates of HMF at discharge in opioid-exposed neonates (OENs). DESIGN: Quality improvement project. SETTING/LOCAL PROBLEM: Underutilizing an HMF and OUD standardized care pathway in an academic medical center led to declining HMF rates at discharge. PARTICIPANTS: Staff nurses in the women and infants department (N = 311). INTERVENTION/MEASUREMENTS: Nurses completed an asynchronous online educational module regarding awareness and use of the HMF and OUD standardized care pathway for supporting HMF in OENs. Monthly infographics were placed in each nursing unit to reinforce content. Nurses completed pre- and posteducation surveys to evaluate their knowledge and use of the pathway. After the education, rates of OENs receiving human milk at discharge were collected from the electronic health record. RESULTS: A total of 240 (77.2%) nurses participated in the educational module; awareness of the pathway increased from 91.5% to 97.3%. HMF rate at discharge significantly increased from 29.8% to 59.4% (p = .03). CONCLUSION: Improved awareness among nurses of a standardized HMF and OUD care pathway was associated with a doubling of HMF rates at discharge in OENs.

RESUMO

Rationale: Opioid use during pregnancy can lead to negative infant health outcomes, including neonatal opioid withdrawal syndrome (NOWS). NOWS comprises gastrointestinal, autonomic nervous system, and neurological dysfunction that manifest during spontaneous withdrawal. Variability in NOWS severity necessitates a more individualized treatment approach. Ultrasonic vocalizations (USVs) in neonatal mice are emitted in isolation as a stress response and are increased during opioid withdrawal, thus modeling a negative affective state that can be utilized to test new treatments. Objectives: We sought to identify the behavioral and USV profile, brainstem transcriptomic adaptations, and role of kappa opioid receptors in USVs during neonatal opioid withdrawal. Methods: We employed a third trimester-approximate opioid exposure model, where neonatal inbred FVB/NJ pups were injected twice-daily with morphine (10mg/kg, s.c.) or saline (0.9%, 20 ul/g, s.c.) from postnatal day(P) 1 to P14. This protocol induces reduced weight gain, hypothermia, thermal hyperalgesia, and increased USVs during spontaneous morphine withdrawal. Results: On P14, there were increased USV emissions and altered USV syllables during withdrawal, including an increase in Complex 3 syllables in FVB/NJ females (but not males). Brainstem bulk mRNA sequencing revealed an upregulation of the kappa opioid receptor (Oprk1), which contributes to withdrawal-induced dysphoria. The kappa opioid receptor (KOR) antagonist, nor-BNI (30 mg/kg, s.c.), significantly reduced USVs in FVB/NJ females, but not males during spontaneous morphine withdrawal. Furthermore, the KOR agonist, U50,488h (0.625 mg/kg, s.c.), was sufficient to increase USVs on P10 (both sexes) and P14 (females only) in FVB/NJ mice. Conclusions: We identified an elevated USV syllable, Complex 3, and a female-specific recruitment of the dynorphin/KOR system in increased USVs associated with neonatal opioid withdrawal severity.

RESUMO

Safe chemicals for drug withdrawal can be extracted from natural sources. This study investigates the effects of clonidine and Thymbra spicata extract (TSE) on mice suffering from morphine withdrawal syndrome. Thymol, which is the active constituent in TSE, was also tested. A total of 90 mice were divided into nine groups. Group 1 was the control group, while Group 2 was given only morphine, and Group 3 received morphine and 0.2 mg/kg of clonidine. Groups 4-6 were given morphine along with 100, 200, and 300 mg/kg of TSE, respectively. Groups 7-9 received morphine plus 30, 60, and 90 mg/kg of Thymol, respectively, for 7 days. An oral naloxone challenge of 3 mg/kg was used to induce withdrawal syndrome in all groups. Improvement of liver enzyme levels (aspartate aminotransferase, alkaline phosphatase, and alanine transaminase) (p < .01) and behavioral responses (frequencies of jumping, frequencies of two-legged standing, Straub tail reaction) (p < .01) were significantly observed in the groups receiving TSE and Thymol (Groups 4-9) compared to Group 2. Additionally, antioxidant activity in these groups was improved compared to Group 2. Nitric oxide significantly decreased in Groups 4 and 6 compared to Groups 2 and 3 (p < .01). Superoxide dismutase increased dramatically in Groups 5, 8, and 9 compared to Groups 2 and 3 (p < .01). Groups 5-9 were significantly different from Group 2 in terms of malondialdehyde levels (p < .01). Certain doses of TSE and Thymol were found to alleviate the narcotics withdrawal symptoms. This similar effect to clonidine can pave the way for their administration in humans.

RESUMO

BACKGROUND: The physical dependence on prescription opioids among cancer survivors remains an under-investigated area, with a scarcity of well-designed prospective studies. METHODS: This single-arm, phase-2 clinical trial in Korea assessed the efficacy and safety of a transdermal buprenorphine patch (TBP) in managing physical dependence on prescription opioids in cancer survivors, as confirmed through the DSM-5 criteria or psychiatric consultation for opioid withdrawal. This study involved a 4-phase treatment protocol of screening, induction/stabilization, discontinuation, and monitoring. The primary outcome was the rate of successful opioid discontinuation, as measured by a negative urine-drug screening at 8 weeks. Key secondary outcomes included the resumption of prescribed opioids, changes in both the Clinical Opioid Withdrawal Scale (COWS) and morphine equivalent daily dose (MEDD), and assessments related to the psychological and physiological aspects of dependence and safety. RESULTS: Thirty-one participants were enrolled. In the intention-to-treat population, the success rate of opioid discontinuation was 58%, with only 2 participants experiencing a resumption of prescribed opioids. Significant reductions were observed in MEDD, which decreased from 98 to 26 mg/day (P < .001), and COWS scores, which decreased from 5.5 to 2.8 (P < .001). Desire to use opioids reduced from 7.0 to 3.0 on a 10-point numeric rating scale (P < .001). Toxicities related to TBP were mild and manageable, without severe precipitated withdrawal symptoms. CONCLUSION: TBP may be considered as an alternative therapeutic option in cancer survivors physically dependent on prescription opioids, especially where sublingual formulations are unavailable.

RESUMO

Objective: The study aims to identify the drugs associated with drug withdrawal syndrome in the Food and Drug Administration Adverse Event Reporting System (FAERS) and estimate their risks of causing withdrawal syndrome. Methods: All the data were collected from FAERS from the first quarter of 2004 to the third quarter of 2023. Disproportionality analyses of odds ratio (ROR) and proportional reported ratio were conducted to identify potential adverse effects signal of drug withdrawal syndrome. Results: A total of 94,370 reports related to withdrawal syndrome from the data. The top 50 drugs with most frequency reported were analyzed, and 29 exhibited a positive signal based on the number of reports. The top three categories of drugs with positive signals included opioids, antidepressant drugs and antianxiety drugs. Other classifications included opioid antagonist, muscle relaxant, antiepileptic drugs, analgesics, hypnotic sedative drugs and antipsychotic drugs. Conclusion: Our analysis of FAERS data yielded a comprehensive list of drugs associated with withdrawal syndrome. This information is vital for healthcare professionals, including doctors and pharmacists, as it aids in better recognition and management of withdrawal symptoms in patients undergoing treatment with these medications.

RESUMO

An increasing number of new psychoactive substances (NPS), such as designer benzodiazepines, are becoming available on the recreational drug market. These are new unregistered substances and thereby an attempt to evade legislation. Often there is very limited clinical information available regarding these NPS, which could result in undesirable clinical outcomes in the management of intoxications, dependencies and withdrawals following NPS use. In this case report we describe a 23-year-old woman, who was admitted to our residential addiction care facility for the detoxification of the designer benzodiazepine bromazolam. Her daily use of 6 mg bromazolam was converted to 20 mg diazepam. Although we expected a higher dose would have been needed, 20 mg was sufficient and was tapered without complications. This case report demonstrates the safe conversion of 6 mg of bromazolam to 20 mg of diazepam by combining the use of fixed-dose and symptom-triggered-dose regimens. More clinical data is necessary to formulate advisory management for the detoxification of bromazolam and other designer benzodiazepines.

RESUMO

Metastatic prostate cancer treatment is based on androgen deprivation, with pharmacological or surgical castration. This treatment may be complemented with the addition of antiandrogenic drugs. In the setting of prostate-specific antigen (PSA) progression and subsequent suspension of the antiandrogenic drug, there might occur a phenomenon of antiandrogen withdrawal, leading to a decrease in PSA and/or improvement in imaging or clinical outcomes after discontinuation of the antiandrogenic agent. Although there are some descriptions of withdrawal after the cessation of enzalutamide, the physiological mechanism behind it, as well as its frequency and impact on patient survival, remain unknown. We present two clinical cases of antiandrogenic withdrawal after enzalutamide discontinuation and discuss potential contributing factors to this phenomenon.

RESUMO

BACKGROUND: Prescription drug monitoring programs (PDMPs) have been widely adopted as a tool to address the prescription opioid epidemic in the United States. PDMP integration and mandatory use policies are 2 approaches states have implemented to increase use of PDMPs by prescribers. While the effectiveness of these approaches is mixed, it is unclear what factors motivated states to implement them. This study examines whether opioid dispensing, adverse health outcomes, or other non-health-related factors motivated implementation of these PDMP approaches. METHODS: Time-to-event analysis was performed using lagged state-year covariates to reflect values from the year prior. Extended Cox regression estimated the association of states' rates of opioid dispensing, prescription opioid overdose deaths, and neonatal opioid withdrawal syndrome with implementation of PDMP integration and mandatory use policies from 2009 to 2020, controlling for demographic and economic factors, state government and political factors, and prior opioid policies. RESULTS: In our main model, prior opioid dispensing (HR 2.31, 95% CI 1.17, 4.57), neonatal opioid withdrawal syndrome hospitalizations (HR 1.55, 95% CI 1.09, 2.19), and number of prior opioid policies (HR 2.13, 95% CI 1.13, 4.00) were associated with mandatory use policies. Prior prescription opioid overdose deaths (HR 1.21, 95% CI 1.08, 1.35) were also associated with mandatory use policies in a model that did not include opioid dispensing or neonatal opioid withdrawal syndrome. No study variables were associated with implementation of PDMP integration. CONCLUSION: Understanding state-level factors associated with implementing PDMP approaches can provide insights into factors that motivate the adoption of future public health interventions.
