RESUMO

INTRODUCTION: Menthol has long been incorporated as a flavor additive in tobacco products and can impact use behaviors. Despite its inclusion in some of the most popular flavored smokeless tobacco (ST) products (e.g., "mint" flavored products), few studies have systematically investigated the impact of menthol on ST use behaviors in prospective empirical studies. Rigorous investigation of ST menthol content on behavioral and physiological outcomes requires ST products with stable and precise levels of menthol; however, commercial product composition variability prevents product comparisons when evaluating the effects of systematic changes in menthol content on clinical outcomes. METHODS: We developed amended loose moist snuff ST products by treating commercially available, unflavored loose ST with an ethanol-based menthol spiking solution or a nonmentholated ethanol control solution to develop test products with different levels of menthol: 0, 1, 3, and 5 mg menthol/g tobacco. We evaluated the stability of menthol content in these products over 24 months and evaluated menthol exposure associated with the products through pharmacokinetic analysis of plasma menthol-glucuronide in human participants (n=22). RESULTS: Menthol content of the amended products was on target, homogenous, and stable for up to 24 months. Menthol exposure (menthol-glucuronide Cmax and AUC) significantly differed between each test product. CONCLUSIONS: These data suggest that stable products with nonoverlapping menthol content can be developed using a menthol spiking solution and can be subsequently administered for clinical assessments of mentholated loose ST. IMPLICATIONS: The results from this study suggest that a menthol spiking solution can be used to mentholate unflavored, loose ST to a target menthol content. With this method, the ST menthol content was stable for at least 24 months, and the products exposed users to menthol in a dose-dependent manner. This method yielded loose ST products with precise, stable levels of menthol to allow systematic evaluation of ST menthol content on clinical outcomes. The method may have applications for systematically evaluating changes in other tobacco product ingredients.

RESUMO

Peg-shaped and missing lateral incisor teeth are common features for patients affected by hypodontia. While improvements in dental appearance may be a strong motivating factor for these patients, providing dental treatment to improve the clinical condition and achieve an acceptable and stable outcome can be complex and lengthy.For patients affected by hypodontia, discussion and consideration of various approaches to their individual treatment are best achieved in a multidisciplinary team environment. This allows debate of options and joint agreement between at least orthodontic and restorative dentistry specialist colleagues, based largely on clinical factors, towards a treatment plan that is acceptable to the patient. As most patients with this lateral incisor form of hypodontia are initially treated as teenagers and young adults, there is also an understanding that treatment outcomes will have lifelong maintenance and resource implications to consider.This paper identifies and discusses the key clinical features that influence the treatment planning process for a patient with either missing or peg lateral incisor teeth. These will often involve consideration of whether to open or close the lateral incisor spaces and whether to restore or replace a peg lateral incisor tooth. The process should be patient-centred, evidence-based, and aim to minimise the lifelong treatment burden, retaining options for future maintenance and retreatment.

RESUMO

DESIGN: A single-centre retrospective case-control study from 2012-2020 comparing the prevalence of apical periodontitis (AP) in patients with autoimmune disorders (AD) against a control group of those without. The different medication groups commonly used for treatment of AD were included for comparison. CASE/CONTROL SELECTION: This study utilised patients' electronic records. These were anonymous. Patient sociodemographic variables were collected and compared. Two cases were removed from selection as they were being treated with dual biologic therapy. DATA ANALYSIS: Both the control group and AP group contained 89 patients. Various additional variables were considered, such as DMFT and a logistical regression analysis was used to correlate between AD and AP. RESULTS: For the autoimmune disease conditions within this study, the authors found a higher prevalence of apical periodontitis than in the control group, 89.9% versus 74.2%, respectively (p = 0.015). Furthermore, those taking conventional disease-modifying drugs such as methotrexate had a lower prevalence than those on biologics. These results were of statistical significance. CONCLUSIONS: Individuals with autoimmune disorders may have increased prevalence of apical periodontitis irrespective of their treatment with biologics or not. A DMFT score can be used to predict the occurrence of AP.

RESUMO

INTRODUCTION: The Tobacco Control Act gives the U.S. Food and Drug Administration authority to establish a reduced-nicotine content standard in combusted cigarettes. This future potential regulation may pose a significant public health benefit; however, black markets may arise to meet demand for normal-nicotine content cigarettes among smokers unwilling to transition to or use an alternative product. AIMS AND METHODS: We determined the behavioral-economic substitutability of illicit normal-nicotine content cigarettes and e-cigarettes for reduced-nicotine content cigarettes in a hypothetical reduced-nicotine regulatory market. Adult cigarette smokers were recruited online to complete hypothetical cigarette purchasing tasks for usual-brand cigarettes, reduced-nicotine content cigarettes, and illicit normal-nicotine content cigarettes, as well as a cross-commodity task in which reduced-nicotine content cigarettes were available across multiple prices and illicit cigarettes were concurrently available for $12/pack. Participants completed two three-item cross-commodity purchasing tasks in which e-cigarettes were available for $4/pod or $12/pod alongside reduced-nicotine content cigarettes and illicit cigarettes. RESULTS: Usual-brand cigarette purchasing was greater than illicit normal-nicotine content cigarettes and less than reduced-nicotine content cigarettes. In the cross-commodity purchasing tasks, illicit cigarettes and e-cigarettes both served as economic substitutes for reduced-nicotine content cigarettes; however, when e-cigarettes were available for $4/pod, they were purchased at greater levels than illicit cigarettes and resulted in greater reductions in reduced-nicotine content cigarettes purchasing than when available for $12/pod. CONCLUSIONS: These data suggest that some smokers are willing to engage in illicit cigarette purchasing in a reduced-nicotine regulatory environment, but e-cigarette availability at lower prices may reduce black-market engagement and shift behavior away from combusted cigarette use. IMPLICATIONS: E-cigarettes available at low, but not high, prices were stronger substitutes for legal, reduced-nicotine content cigarettes than illegal, normal-nicotine content cigarettes in a hypothetical reduced-nicotine tobacco market. Our findings suggest the availability of relatively inexpensive e-cigarettes may reduce illicit cigarette purchasing and combusted cigarette use under a reduced-nicotine cigarette standard.

RESUMO

Acalabrutinib is a Bruton tyrosine kinase inhibitor approved for patients with chronic lymphocytic leukemia (CLL). ASCEND is the pivotal phase 3 study of acalabrutinib versus investigator's choice of idelalisib plus rituximab (IdR) or bendamustine plus rituximab (BR) in patients with relapsed/refractory (R/R) CLL. In the primary ASCEND analysis (median 16.1-month follow-up), acalabrutinib showed superior efficacy with an acceptable tolerability profile versus IdR/BR; here, we report final ~4 year follow-up results. Patients with R/R CLL received oral acalabrutinib 100 mg twice daily until progression or unacceptable toxicity, or investigator's choice of IdR or BR. A total of 310 patients (acalabrutinib, n = 155; IdR, n = 119; BR, n = 36) were enrolled. At median follow-up of 46.5 months (acalabrutinib) and 45.3 months (IdR/BR), acalabrutinib significantly prolonged investigator-assessed progression-free survival (PFS) versus IdR/BR (median, not reached [NR] vs 16.8 months; P < 0.001); 42-month PFS rates were 62% (acalabrutinib) versus 19% (IdR/BR). Median overall survival (OS) was NR (both arms); 42-month OS rates were 78% (acalabrutinib) versus 65% (IdR/BR). Adverse events led to drug discontinuation in 23%, 67%, and 17% of patients in the acalabrutinib, IdR, and BR arms, respectively. Events of clinical interest (acalabrutinib vs IdR/BR) included all-grade atrial fibrillation/flutter (8% vs 3%), all-grade hypertension (8% vs 5%), all-grade major hemorrhage (3% vs 3%), grade ≥3 infections (29% vs 29%), and second primary malignancies excluding nonmelanoma skin cancer (7% vs 2%). At ~4 years follow-up, acalabrutinib maintained favorable efficacy versus standard-of-care regimens and a consistent tolerability profile in patients with R/R CLL.

RESUMO

Dysphonia is a common presenting symptom to the outpatient ear, nose and throat team and the need to have a systematic approach to its investigation and management is imperative. Red flag features combined with clinical examination including flexible nasoendoscopy will help to identify laryngeal causes of dysphonia. Vocal cord palsy can have both laryngeal and extralaryngeal aetiologies including Ortner's syndrome. We present a case where a woman in her 70s was referred with persistent hoarseness, found to have an isolated vocal cord palsy with CT scan revealing a very large hiatus hernia producing mass effect at the aortopulmonary window with no other pathology identified. To our knowledge, this is the second case in the literature of a hiatus hernia causing a vocal cord palsy. This case underpins the need for prompt assessment by flexible laryngoscopy, and consideration of extralaryngeal causes of vocal cord palsy during a dysphonia assessment.

RESUMO

Multiple haemangiomas of the head and neck area have been reported sporadically in the literature. Concurrent subglottic and carotid sheath haemangiomas have not been reported before in the paediatric population. The authors present the case of a 13-week-old child admitted under the paediatric ENT team with stridor. Diagnostic micro-laryngoscopy identified a subglottic haemangioma as the cause of stridor and subsequent magnetic resonance imaging demonstrated an incidental 7 cm carotid sheath lesion extending from the skull base to the superior mediastinum. Subsequent biopsy confirmed a benign infantile haemangioma. To our knowledge, this is the first reported case of concurrent subglottic and carotid sheath infantile haemangiomas in a paediatric patient. Here we discuss the clinical features and management of infantile haemangioma.

RESUMO

BACKGROUND/AIMS: Approximately 20% of patients with maxillofacial trauma are women, but few articles have analysed this. The aim of this multicentric, prospective, epidemiological study was to analyse the characteristics of maxillofacial fractures in the female population managed in 14 maxillofacial surgery departments on five continents over a 1-year period. METHODS: The following data were collected: age (0-18, 19-64, or ≥65 years), cause and mechanism of the maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injury, day of trauma, timing and type of treatment, and length of hospitalization. RESULTS: Between 30 September 2019 and 4 October 2020, 562 of 2387 patients hospitalized with maxillofacial trauma were females (24%; M: F ratio, 3.2:1) aged between 1 and 96 years (median age, 37 years). Most fractures occurred in patients aged 20-39 years. The main causes were falls (43% [median age, 60.5 years]), which were more common in Australian, European and American units (p < .001). They were followed by road traffic accidents (35% [median age, 29.5 years]). Assaults (15% [median age, 31.5 years]) were statistically associated with alcohol and/or drug abuse (p < .001). Of all patients, 39% underwent open reduction and internal fixation, 36% did not receive surgical treatment, and 25% underwent closed reduction. CONCLUSION: Falls were the main cause of maxillofacial injury in the female population in countries with ageing populations, while road traffic accidents were the main cause in African and some Asian centres, especially in patients ≤65 years. Assaults remain a significant cause of trauma, primarily in patients aged 19-64 years, and they are related to alcohol use.

RESUMO

As cannabis policy changes, there is an urgent need to understand interactions between cannabis and alcohol couse. An online sample of 711 adult past-month cannabis and alcohol users completed both single-item hypothetical purchasing tasks for cannabis and alcohol and cross-commodity purchasing tasks assessing adjusting-price cannabis with concurrently available, fixed-price alcohol, and vice versa. Participants provided information about cannabis and alcohol use patterns, and completed the Alcohol and Cannabis Use Disorder Identification Tests (AUDIT and CUDIT, respectively). Group data showed that cannabis and alcohol served as complements (as the price of the adjusting-price commodity increased, consumption of both commodities decreased). However, individual data showed substantial variability with nontrivial proportions showing patterns of complementarity, substitution, and independence. More negative slopes (greater complementarity) for fixed-price cannabis and alcohol were both associated with greater self-reported drug consumption and CUDIT and AUDIT scores. The negative relation between cross-price slope and CUDIT/AUDIT score indicates that individuals who treat cannabis and alcohol more as complements are more likely to experience disordered use. Based on these cross-commodity purchasing data, when both cannabis and alcohol are concurrently available at low prices, both may be used at high levels, whereas limiting consumption of one commodity (e.g., through increased price) may reduce consumption of the other. These data show the importance of examining individual participant analyses of behavioral economic drug interactions and suggest that manipulation of cost (e.g., through taxes) or cosale restrictions are potential public health regulatory mechanisms for reducing alcohol and cannabis use and couse behaviors.

RESUMO

BACKGROUND: Mescaline is a naturally occurring psychoactive phenethylamine found in several cacti and historically used ceremonially by Indigenous and Latin American populations. Broader recognition of its possible therapeutic value in Western science began in the 1950s; however, knowledge of the safety profile of mescaline and the extent of its use remains limited. The primary aim of this study is to examine the epidemiology of mescaline use among English-speaking adults. METHODS: About 452 respondents completed a web-based survey designed to assess their previous experience with mescaline (subjective effects, outcome measures, and mescaline type used). RESULTS: Most respondents reported that they had consumed mescaline infrequently (⩽once/year), for spiritual exploration or to connect with nature (74%). A small number of respondents reported drug craving/desire (9%), whereas very few reported legal (1%), or psychological problems (1%) related to its use, and none reported seeking any medical attention. Overall, respondents rated the acute mystical-type effects as "moderate," ego-dissolution and psychological insight effects as "slight," and challenging effects as "very slight." Most respondents reported that they used Peyote and San Pedro in their most memorable mescaline experience. Overall, the intensity of acute mescaline effects did not differ between mescaline types. About 50% of the sample reported having a psychiatric condition (i.e. depression, anxiety, etc.), and most (>67%) reported improvements in these conditions following their most memorable experience with mescaline. CONCLUSION: Findings indicate that the mescaline in any form may produce a psychedelic experience that is associated with the spiritual significance and improvements in the mental health with low potential for abuse.

RESUMO

Cannabis products available for retail purchase are often marketed based on purported plant species (e.g., "indica" or "sativa"). The cannabis industry frequently claims that indica versus sativa cannabis elicits unique effects and/or is useful for different therapeutic indications. Few studies have evaluated use patterns, beliefs, subjective experiences, and situations in which individuals use indica versus sativa. A convenience sample of cannabis users (n = 179) was surveyed via Amazon Mechanical Turk (mTurk). Participants were asked about their prior use of, subjective experiences with, and opinions on indica versus sativa cannabis and completed hypothetical purchasing tasks for both cannabis subtypes. Participants reported a greater preference to use indica in the evening and sativa in the morning and afternoon. Participants were more likely to perceive feeling "sleepy/tired" or "relaxed" after using indica and "alert," "energized," and "motivated" after using sativa. Respondents were more likely to endorse wanting to use indica if they were going to sleep soon but more likely to use sativa at a party. Hypothetical purchasing patterns (i.e., grams of cannabis purchased as a function of escalating price) did not differ between indica and sativa, suggesting that demand was similar. Taken together, cannabis users retrospectively report feeling different effects from indica and sativa; however, demand generally did not differ between cannabis subtypes, suggesting situational factors could influence whether someone uses indica or sativa. Placebo-controlled, blinded studies are needed to characterize the pharmacodynamics and chemical composition of indica and sativa cannabis and to determine whether user expectancies contribute to differences in perceived indica/sativa effects.

RESUMO

Delay discounting and operant demand are two behavioral economic constructs that tend to covary, by degree, with cigarette smoking status. Given historically robust associations between adverse health outcomes of smoking, a strong preference for immediate reinforcement (measured with delay discounting), and excessive motivation to smoke cigarettes (measured with operant demand), researchers have made numerous attempts to attenuate the extent to which behaviors corresponding to these constructs acutely appear in smokers. One approach is episodic future thinking, which can reportedly increase the impact of future events on present decision making as well as reduce the reinforcing value of cigarettes. Graphic cigarette pack warning labels may also reduce smoking by increased future orientation. Experiment 1 evaluated the combined effects of episodic future thinking and graphic warning labels on delay discounting; Experiment 2 evaluated solely the effects of episodic future thinking on delay discounting and operant demand. We observed no statistically significant effects of episodic future thinking when combined with graphic warning labels or when assessed on its own. These results serve as a call for further research on the boundary conditions of experimental techniques reported to alter behaviors associated with cigarette smoking.

RESUMO

Data sources The review carried out electronic searches using several online databases through November 2018, namely PubMed, Virtual Health Library, Cochrane Library and Scopus. Terms searched for on these databases included third molar, flap and variations thereof. A grey literature search was also conducted.Study selection In total, 2,455 articles were identified,1,449 being duplicates. Additionally, 1,006 articles remained for assessment which, with clear exclusion criteria listed, was reduced to 20. From the 20 incorporated into the review, 18 articles were utilised for meta-analysis. Three of the researchers were involved in assessing the articles after research management software was used to remove the aforementioned duplicates. A Cohen's kappa index was calculated to confirm inter-rater consistency using 10% of the articles.Data extraction and synthesis Data extraction followed the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidance.Results From their systematic review and meta-analyses, the authors found that flap design had no effect on common post-operative complications including pain, trismus, dehiscence, or osteitis. The triangular flap did, however, have greater post-operative ecchymosis but reduced periodontal probing depth on day seven when compared to the envelope flap in mandibular third molar surgeries.Conclusions Third molar surgery is carried out across all facets of dentistry, including general and specialised. Further studies must be carried out that look specifically at these variables utilising randomised controlled trials so a consensus can be achieved across the profession of which flap is of superior design.

RESUMO

As fatal overdoses from synthetic opioids continue to rise, we need to understand decision-making processes underlying heroin and synthetic opioid use. This study evaluated the influence of sample impurity and fatal overdose risk on hypothetical heroin use. Individuals who currently use heroin (n = 69) were recruited online. Participants completed two probability-discounting tasks evaluating the likelihood of using a sample of heroin based on the likelihood of sample impurity and likelihood of fatal overdose, where greater discounting represented reduced use likelihood. Prior to completing the probability-discounting tasks, participants were randomized to read one of four prompts varying by the presence of information on heroin effects and active (e.g., fentanyl) or inert impurities. Influence of prompts on discounting processes and associations among probability-discounting measures, opioid use behaviors, and dependence severity were evaluated. Heroin use likelihood decreased with increased impurity or overdose risk and in a generally orderly fashion. Discounting was greater (i.e., reduced heroin use likelihood) when overdose risk, compared to sample impurity, was manipulated. Less discounting was associated with more severe opioid dependence. Discounting did not differ among prompts for either task. Individuals might adjust their heroin-use behavior to reduce harm with risk-related information. Greater discounting elicited by overdose relative to impurity risk suggests that equating adulteration and overdose risk is essential for harm reduction. Expanded access to drug checking services, which inform impurity and overdose risk, can reduce fatal overdoses. Due to fear of legal sanctions for these services, legislation and judicial decisions should explicitly protect these services. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

RESUMO

BACKGROUND: Identifying factors that can be targeted in intervention/prevention programs aimed at reducing marijuana-(MJ) related consequences is of critical concern due to the changing legislative landscape of MJ. The dualistic model of passion for MJ has indicated that two factors, obsessive passion (OP) and harmonious passion (HP), have unique effects associated with MJ use outcomes. New research suggests that a quadripartite approach could provide a more nuanced method to interpret risk and protective factors associated with MJ use. Therefore, we used moderation to investigate the associations among OP, HP, and MJ use outcomes. METHOD: A community sample of frequent MJ users was recruited using internet-based advertisements and completed web-based surveys (n=161; M age=27.3, SD=8.9; Male=87%; White/Caucasian=86%; M past30-dayMJuse=22.3, SD=9.9). HP was tested as the moderator between OP, and MJ related outcomes and conditional effects (+/-1 SD) were examined when interaction effects were significant. RESULTS: Only main effects for OP had a relation to quantity/frequency of MJ use and MJ intoxication, while main effects for OP and HP were associated with reduction attempts. Interaction effects were significant for MJ consequences, craving, and life satisfaction. Neither OP nor HP were significantly associated with substance use outcomes. CONCLUSIONS: Findings demonstrate that Pure OP and Mixed Passion are associated with greater risk. Mixed Passion may be a precursor to Pure OP and experiencing MJ-related consequences. Furthermore, Mixed Passion and Pure OP may be important targets for intervention/prevention programs designed to reduce negative outcomes.

RESUMO

The MCRN-003/CCTGMYX.1 is a single arm phase II trial of weekly carfilzomib, cyclophosphamide and dexamethasone (wKCd), exploring a convenient immunomodulator (IMiD)-free regimen in relapsed myeloma. Weekly carfilzomib (20/70 mg/m2 ), dexamethasone 40 mg and cyclophosphamide 300 mg/m2 was delivered over 28-day cycles. The primary endpoint was overall response after four cycles. Secondary endpoints included toxicity, response depth, PFS and OS. Exploratory endpoints included the impact of cytogenetics, prior therapy exposure and serum free light chain (sFLC) escape; 76 patients were accrued. The ORR was 85% (68% ≥very good partial response [VGPR] and 29% ≥complete response [CR]). The median OS and PFS were 27 and 17 months respectively. High-risk cytogenetics conferred a worse ORR (75% vs. 97%, p = .013) and median OS (18 months vs. NR, p = .002) with a trend toward a worse median PFS (14 vs. 22 months, p = .06). Prior proteasome inhibitor (PI) or lenalidomide did not influence OS or PFS. The sFLC was noted in 15% of patients with a median PFS of 17 months when included as a progression event. The most common ≥ grade 3 non-hematologic adverse events were infectious (40%), vascular (17%) and cardiac (15%). The wKCD is a safe and effective regimen in relapse, especially for patients ineligible for lenalidomide-based therapies.

RESUMO

Attention-deficit/hyperactivity disorder (ADHD) is associated with increased risk of detrimental life outcomes. Recent research also indicates that ADHD is associated with sexual risk behavior, such as unprotected sex. Some risky sexual behaviors may be driven, in part, by preference for immediate rewards, referred to as delay discounting, which is prominent in etiological models of ADHD. Therefore, the present study examined the effect of delay on preference for both monetary and sexual outcomes in adults with many ADHD symptoms (both on and off medication) and with fewer ADHD symptoms. Online participants (N = 275; n = 161 males, n = 114 females) completed a monetary delay discounting task, assessing preference for smaller sooner versus larger delayed hypothetical money, and the Sexual Delay Discounting Task, assessing preference for condom use in hypothetical casual sex scenarios based on delay until condom availability. Those with greater ADHD symptoms discounted delayed monetary outcomes as well as delayed condom-protected sex (i.e., preferred sooner money rewards and immediate unprotected sex) significantly more than those with fewer symptoms; however, no effect of current medication use was found across monetary or sexual delay discounting among those with greater ADHD symptoms. This study is the first to demonstrate the relation between ADHD symptoms and reduced condom-use likelihood. Increased discounting of delayed condom-protected sex might constitute one mechanism of risky sexual behavior among individuals with ADHD symptoms. Interventions geared toward increasing condom use in situations in which condoms may otherwise be unavailable, may mitigate risky sexual behaviors and their associated harms in this population.

RESUMO

Behavioral processes underlying sexual behavior are important for understanding normal human functioning and risk behavior leading to sexually transmitted infections (STIs). This systematic review examines delay and probability discounting in human sexual behavior through synthesis of 50 peer-reviewed, original research articles. Sixteen studies focusing exclusively on monetary delay discounting found small effect size positive correlations with sexual risk behaviors. Eleven studies examined delay or probability discounting of sexual behavior itself using tasks that varied duration, frequency, or quality of sex to determine value. Results show delay and uncertainty of sex causes systematic decreases in value. These studies also show consistent medium effect size relationships between sexual discounting measures and sexual health and substance use, supporting utility above and beyond monetary discounting. Twenty-three studies have modeled clinically relevant decision-making, examining effects of delay until condom availability and STI contraction probability on condom use. Observational and experimental designs found condom-use discounting is elevated in high-risk substance use populations, is sensitive to context (e.g., partner desirability), and is more robustly related to sexual risk compared with monetary discounting or condom use decisions when no delay/uncertainty was involved. Administering cocaine, alcohol, and, for some participants, methamphetamine increased condom-use discounting with minimal effect on monetary discounting or condom use when no delay/uncertainty was involved. Reviewed studies robustly support that sexual behavior is highly dependent on delay and probability discounting, and that these processes strongly contribute to sexual risk. Future research should exploit these systematic relationships to design behavioral and pharmacological approaches to decrease sexual risk behavior.
