RESUMO

Mindfulness witnessed a substantial popularity surge in the past decade, especially as digitally self-administered interventions became available at relatively low costs. Yet, it is uncertain whether they effectively help reduce stress. In a preregistered (OSF https://doi.org/10.17605/OSF.IO/UF4JZ ; retrospective registration at ClinicalTrials.gov NCT06308744 ) multi-site study (nsites = 37, nparticipants = 2,239, 70.4% women, Mage = 22.4, s.d.age = 10.1, all fluent English speakers), we experimentally tested whether four single, standalone mindfulness exercises effectively reduced stress, using Bayesian mixed-effects models. All exercises proved to be more efficacious than the active control. We observed a mean difference of 0.27 (d = -0.56; 95% confidence interval, -0.43 to -0.69) between the control condition (M = 1.95, s.d. = 0.50) and the condition with the largest stress reduction (body scan: M = 1.68, s.d. = 0.46). Our findings suggest that mindfulness may be beneficial for reducing self-reported short-term stress for English speakers from higher-income countries.

RESUMO

In this paper, I explore the challenges of legalizing cannabis in Ohio, focusing on the passing of the Issue 2 Bill, legislative resistance, and public response. I propose five strategies for effective policy change: persistent advocacy post policy change success, establishing strong coalitions, empowering grassroots movements, promoting rigorous data-driven research, and launching public education campaigns. I offer a detailed analysis of the interaction between public opinion and legislative action in cannabis legalization and its implications for substance-related policy change.

RESUMO

In contrast to overnight deprivation versus satiety studies, a small number of placebo-controlled studies have failed to find that nicotine administration reduces attentional bias (AB) to smoking cues. To assess the reliability of this failure and to address the duration and salience of AB in smokers versus never-smokers, we used a longer-than-typical (i.e., 3,000 ms) smoking cue-presentation time in a placebo-controlled trial of smokers and never-smokers. We aimed to assess whether a nicotine patch (i.e., active vs. placebo) attenuates continuously assessed eye gaze-measured AB to smoking cues across 3,000 ms in 32 habitual, overnight-deprived smokers and smoker-nonsmoker differences compared to 32 never-smokers. We presented a series of picture pairs (i.e., one smoking-related and one affectively neutral control picture) simultaneously to assess AB. Participants attended a 14 mg nicotine patch and a placebo patch session in a randomized order. The habitual smokers were 12-18 hr nicotine-deprived during both sessions. Smokers demonstrated a stronger AB toward smoking cues than never-smokers across the entire 3,000 ms cue-presentation time. Nicotine did not significantly reduce the AB to smoking cues but the AB was strongly and positively related to deprivation-associated cravings in smokers. Patch-delivered nicotine did not reduce AB to smoking cues presented for up to 3,000 ms, even though smoker-nonsmoker differences in bias remained. Assessments of longer cue presentations and more subtle cues may provide nuance not currently captured by existing studies, because of potential demand effects in designs that contrast overnight versus sated state effects on AB.

RESUMO

Background: Expectancies, motives, and attitudes toward substances are cognitive factors that partially account for substance use; however, existing measures tend to have monotonous phrasing, diverging from the enthusiastic attitude toward the perceived benefits of substance use exhibited by those who use substances regularly in informal settings. Objective: I aimed to characterize a new cognitive maintenance factor that precedes substance use by creating a brief, multidimensional measure to capture this tone nuance, which I called the Enthusiastic Substance Use Attitudes Scale (ESUAS). Method: Undergraduate students (n = 198) between ages 18 and 62 (M = 19.15, SD = 3.65; 66.2% women; 71.71% White) completed the study for course credit. Results: I used exploratory and confirmatory factor analyses to reduce a 90-item item pool based on a comprehensive qualitative thematic analysis of social media, traditional media, and the scientific literature to an 18-item hierarchical bifactor model. This model contained nine specific factors, which are (1) sociability, (2) enjoyment, (3) physical health, (4) mental health, (5) relaxation, (6) personal growth, (7) performance enhancement, (8) boredom, and (9) life processing; two general factors, which are (1) substance-induced emotion regulation and (2) substance-based assistance; and a higher-order single factor above the nine specific factors - resulting in twelve highly internally consistent, empirically supported scales. Further, the ESUAS demonstrated excellent structural, convergent, divergent, incremental, and diagnostic validity. The degree of enthusiasm towards substance use positively related to substance use disorder symptomology, polysubstance use, neuroticism, and difficulty with regulating emotions while negatively relating to one's psychological quality of life and agreeableness. Conclusion: The ESUAS may be an effective tool for professionals to characterize these enthusiastic attitudes further and measure a more ecologically valid view of the perceived benefits of substance use among those who use substances, thereby developing a more compassionate, non-stigmatizing understanding within the general public, advancing medicinal uses of illicit substances, and improving conceptualizations and treatments.

RESUMO

Background: The medial patellofemoral ligament (MPFL) is the primary soft tissue restraint to lateral patellar translation and is often disrupted by lateral patellar dislocation. Surgical management for recurrent patellar instability focuses on restoring the MPFL function with repair or reconstruction techniques. Recent studies have favored reconstruction over repair; however, long-term comparative studies are limited. Purpose: To compare long-term clinical outcomes, complications, and recurrence rates of isolated MPFL reconstruction and MPFL repair for recurrent lateral patellar instability. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 55 patients (n = 58 knees) with recurrent lateral patellar instability were treated between 2005 and 2012 with either MPFL repair or MPFL reconstruction. The exclusion criteria were previous or concomitant tibial tubercle osteotomy or trochleoplasty and follow-up of <8 years. Pre- and postoperative descriptive, surgical, imaging, and clinical data were recorded for each patient. Results: MPFL repair was performed on 26 patients (n = 29 knees; 14 women, 15 men), with a mean age of 18.4 years. MPFL reconstruction was performed on 29 patients (n = 29 knees; 18 women, 11 men), with a mean age of 18.2 years. At a mean follow-up of 12 years (range, 8.3-18.9 years), the reconstruction group had a significantly lower rate of recurrent dislocation compared with the repair group (14% vs 41%; P = .019). There were no differences in the number of preoperative dislocations or tibial tubercle-trochlear groove distance. The reconstruction group had significantly more time from initial injury to surgery compared with the repair group (median, 1460 days vs 627 days; P = .007). There were no differences in postoperative Tegner, Lysholm, or Kujala scores at the final follow-up. In addition, no statistically significant differences were detected in return to sport (RTS) rates (repair [81%] vs reconstruction [75%]; P = .610) or reoperation rates for recurrent instability (repair [21%] vs reconstruction [7%]; P = .13). Conclusion: MPFL repair resulted in a nearly 3-fold higher rate of recurrent patellar dislocation (41% vs 14%) at the long-term follow-up compared with MPFL reconstruction. Given this disparate rate, the authors recommend MPFL reconstruction over repair because of the lower failure rate and similar, if not superior, clinical outcomes and RTS.

RESUMO

BACKGROUND: Gluteus maximus tendon transfer has recently been described as a treatment option for irreparable abductor tendon tears. The purpose of this study was to systematically review outcomes following gluteus maximus tendon transfer for hip abductor deficiency. METHODS: The published literature was queried for outcomes following gluteus maximus transfer in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Outcomes of interest included preoperative and postoperative functional scores, resolution of pain and gait abnormalities, postoperative rehabilitation protocols, surgical complications, reoperation rates, and postoperative magnetic resonance imaging. In total, 10 studies with a total of 125 patients (76% women) with a mean age of 67 years (range, 30 to 87) were identified for inclusion. RESULTS: Modified Harris Hip Score (+30.1 ± 6.6 [95% confidence interval: +15.5 to +46.5]) and Visual Analog Scale for pain (-4.1 ± 1.1 [95% confidence interval: -7.1 to -1.0]) were improved following gluteus maximus transfer, compared to preoperative levels. No significant improvement was noted in abduction strength and 33% of patients demonstrated a residual Trendelenburg gait postoperatively. The overall complication rate was 5.6% (7 of 125), with a reoperation rate of 1.6% (2 of 125). CONCLUSIONS: Gluteus maximus tendon transfer for abductor insufficiency has demonstrated reliable outcomes at 3 years, with improvement in hip function and pain. However, patients demonstrate modest improvements in abduction strength, and a significant subset will continue to demonstrate a Trendelenburg gait postoperatively.

RESUMO

BACKGROUND: Arthrofibrosis (AF) after anterior cruciate ligament reconstruction (ACLR) remains a challenge. There is a paucity of data on arthroscopic interventions for AF after ACLR. PURPOSE: To (1) describe the patient, injury, and surgical characteristics and patient-reported outcomes (PROs) of those requiring an arthroscopic intervention for loss of motion after ACLR and (2) compare outcomes between patients undergoing an early intervention (within 3 months) versus those undergoing a late intervention (after 3 months). STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Patients with a history of ACLR and a subsequent operative procedure for postoperative AF at a single institution between 2000 and 2018 were retrospectively identified. Arthroscopic interventions included lysis of adhesions, capsular release with or without manipulation under anesthesia, and excision of cyclops lesions. Patients were excluded if they had a knee dislocation or multiple-ligament injury, a periarticular fracture, or less than 2-year follow-up from the arthroscopic intervention. PROs including the Tegner activity score, visual analog scale pain score, and International Knee Documentation Committee score as well as knee range of motion (ROM) were recorded. RESULTS: A total of 40 patients were included with a mean age of 27.2 years (range, 11.0-63.8 years) at surgery and a mean follow-up of 10.0 years (range, 2.9-20.7 years). The mean preoperative flexion and extension were 102° (range, 40°-150°) and 8° (range, 0°-25°), respectively. The mean postoperative flexion and extension were 131° (range, 110° to 150°) and 0° (range, -10° to 5°), respectively. After the arthroscopic intervention, the mean ROM improved from 94° (range, 40°-140°) preoperatively to 131° (range, 107°-152°) at final follow-up (P < .001), and the visual analog scale pain score improved from 3.0 preoperatively to 1.2 postoperatively (P = .001). Overall, 13 patients (32.5%) underwent an intervention within 3 months and 27 (67.5%) after 3 months. The early intervention group had a higher postoperative International Knee Documentation Committee score compared with the late intervention group (86.8 vs 71.7, respectively; P = .035). CONCLUSION: An arthroscopic intervention for AF after ACLR successfully improved knee ROM and pain. Patients who underwent either early or late surgery obtained satisfactory motion and function, although improved PROs were observed when the intervention occurred within 3 months of the primary procedure.

RESUMO

OBJECTIVE: Recent research suggests potential therapeutic benefits of cannabis-derived products, a lower risk profile than other illicit substances, and significant functional improvement from reduced use. Likewise, low abstinence rates and low motivation to achieve abstinence among those with cannabis use disorder (CUD) are the norm. As such, the harm reduction model has gained traction among substance use scientists and health care professionals as a viable alternative approach. Yet, to date no formal definition of cannabis harm reduction has been proposed. METHOD: We reviewed the literature, including two recent empirical papers published in the Psychology of Addictive Behaviors, Sherman et al. (2022) and Borodovsky et al. (2022), which demonstrate that harm reduction is sufficient to achieve functional improvement. We then propose and define a harm reduction approach for cannabis use research and treatment, and argue why this approach is a timely, necessary discussion. RESULTS: We suggest that a cannabis harm reduction approach includes treatment, research, and education initiatives that reduce the public health burden of cannabis use. This approach includes interventions that reduce functional impairment and risk from cannabis, reduced or managed use, and sometimes, but not necessarily, abstinence. Psychoeducation for treatment providers, legislative barriers, and research recommendations are also discussed. CONCLUSIONS: Research and treatment for CUD has historically focused on cannabis abstinence. Treatment trials rarely yield durable abstinence rates, and reduction has recently been tied to functional improvement. We comment on Sherman et al. (2022) and Borodovsky et al. (2022) and propose a shift toward a cannabis harm reduction approach. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

Purpose: To compare the clinical outcomes of operative and nonoperative management, identify risk factors for recurrent instability, and identify risk factors for progression to surgery after failed nonoperative management for patients with first-time anterior shoulder dislocation after the age of 50 years. Methods: An established geographic medical record system was used to identify patients who experienced a first-time anterior shoulder dislocation after the age of 50 years. Patient medical records were reviewed to identify treatment decisions and outcomes of interest, including rates of frozen shoulder and nerve palsy, progression to osteoarthritis, recurrent instability, and progression to surgery. Outcomes were evaluated using Chi-square tests and survivorship curves were generated using Kaplan-Meier methods. A Cox model was developed to evaluate for potential risk factors of recurrent instability and progression to surgery after an initial trail of at least 3 months of nonoperative treatment. Results: 179 patients were included with a mean follow-up of 11 years. 14% (n = 26) underwent early surgery within 3 months and 86% (n = 153) were initially treated nonoperatively. Mean age (59 years), was similar for both groups, but those that underwent early surgery had an increased rate of full-thickness rotator cuff tears (82% vs 55%; P = .01), labral tears (24% vs 8.0%; P = .01), and humeral head fracture (23% vs 8.5%; P = .03). When comparing the early surgery group to the nonoperative group, there were similar rates of persistent moderate-severe pain (19% vs 17%; P = .78) and frozen shoulder (8 vs 9%, respectively; P = .87) at final follow-up. Although nerve palsy (19% vs 8%; P = .08) and progression to osteoarthritis (20% vs 14%; P = .40) were more common in surgical patients, they experienced lower rates of recurrent instability after surgical intervention (0% vs 15%; P = .03) compared to nonoperatively treated patients. Increasing number of instability events prior to presentation was the greatest risk factor for recurrent instability (HR 232; P < .01). Fourteen percent (n = 21) failed initial nonoperative treatment and proceeded to surgical intervention at an average of 4.6 years after the initial instability event, and the greatest risk factors for progression to surgery were recurrent instability (HR 3.41; P < .01). Conclusions: Although the majority of patients >50 years that experience ASI are treated nonoperatively, those that require surgery tend to have more significant injury pathology, a lower risk of recurrent instability after surgery, but a higher progression to osteoarthritis compared to patients that do not require surgical intervention. There was no difference in pain severity at final follow-up, rates of frozen shoulder or nerve palsy between patients who underwent initial nonoperative treatment after instability and those who underwent surgery. A history of multiple instability episodes prior to presentation was the greatest predictor of recurrent instability and failure of nonoperative treatment and progression to surgery. Level of Evidence: Level III, retrospective cohort study.

RESUMO

Hip abductor deficiency resulting from gluteus medius and minimus pathology is increasingly recognized as a generator of lateral-sided hip pain. In the setting of a failed gluteus medius repair or in patients with irreparable tears, transfer of the anterior portion of the gluteus maximus muscle can be performed to treat gluteal abductor deficiency. The classic description of the gluteus maximus transfer technique relies solely on bone tunnel fixation. This article describes a reproducible technique that incorporates the addition of a distal row to the tendon transfer, which may improve fixation by both compressing the tendon transfer to the greater trochanter and providing improved biomechanical strength to the transfer.

RESUMO

Background: There is a paucity of research on the management of partial-thickness tears of the distal bicep tendon, and even less is known about the long-term outcomes of this condition. Purpose: To identify patients with partial-thickness distal bicep tendon tears and determine (1) patient characteristics and treatment strategies, (2) long-term outcomes, and (3) any identifiable risk factors for progression to surgery or complete tear. Study Design: Case-control study; Level of evidence, 3. Methods: A fellowship-trained musculoskeletal radiologist identified patients diagnosed with a partial-thickness distal bicep tendon tear on magnetic resonance imaging between 1996 and 2016. Medical records were reviewed to confirm the diagnosis and record study details. Multivariate logistic regression models were created using baseline characteristics, injury details, and physical examination findings to predict operative intervention. Results: In total, 111 patients met inclusion criteria (54 treated operatively, 57 treated nonoperatively), with 53% of tears in the nondominant arm and a mean follow-up time after surgery of 9.7 ± 6.5 years. Only 5% of patients progressed to full-thickness tears during the study period, at a mean of 35 months after the initial diagnosis. Patients who were nonoperatively treated were less likely to miss time from work (12% vs 61%; P < .001) and missed fewer days (30 vs 97 days; P < .016) than those treated surgically. Multivariate regression analyses demonstrated increased risk of progression to surgery with older age at initial consult (unit odds ratio [OR], 1.1), tenderness to palpation (OR, 7.5), and supination weakness (OR, 24.8). Supination weakness at initial consult was a statistically significant predictor for surgical intervention (OR, 24.8; P = .001). Conclusion: Clinical outcomes were favorable for patients regardless of treatment strategy. Approximately 50% of patients were treated surgically; patients with supination weakness were 24 times more likely to undergo surgery than those without. Progression to full-thickness tear was a relatively uncommon reason for surgical intervention, with only 5% of patients progressing to full-thickness tears during the study period and the majority occurring within 3 months of initial diagnosis.

RESUMO

PURPOSE: Prior studies of enhanced recovery protocols (ERP) have been conducted at large institutions with abundant resources. These results may not apply at institutions with less resources directed to quality improvement efforts. The purpose of this study was to assess the value of a minimalistic enhanced recovery protocol in reducing length of stay (LOS) following PSF for adolescent idiopathic scoliosis. We hypothesized that accelerated transition to oral pain medications and mobilization alone could shorten hospital length of stay in the absence of a formal multimodal pain regimen. METHODS: AIS patients aged 10-18 who underwent PSF at a tertiary pediatric hospital between January 1, 2014 and December 31, 2017 were reviewed. The study population was further narrowed to consecutive patients from a single surgeon's practice that piloted the modified ERP. Reservation from key stakeholders regarding the feasibility of implementing widespread protocol change led to the minimal alterations made to the postoperative protocol following PSF. Patients were divided into either the Standard Recovery Protocol (SRP) or Enhanced Recovery Protocol (ERP). Primary variables analyzed were hospital LOS, complications, readmissions, and total narcotic requirement. RESULTS: A total of 92 patients met inclusion criteria. SRP and ERP groups consisted of 44 (47.8%) and 48 (52.2%) patients. There was no difference between the two groups with regard to age, sex, and ASA score (p > 0.05). Fusion levels and EBL did not differ between treatment groups (p > 0.05). PCA pumps were discontinued later in the SRP group (39.5 ± 4.3 h) compared to the ERP group (17.4 ± 4.1 h, p < 0.0001). Narcotic requirement was similar between groups (p = 0.94) Patients in the SRP group had longer hospital stays than patients in the ERP group (p < 0.0001). 83% of the ERP group had LOS ≤ 3 days compared to 0% in the SRP group, whose mean LOS was 4.2 days. There was no difference in complications between the groups (2.2% vs 6.0%, p = 0.62). Readmission to the hospital within 30 days of surgery was rare in either group (2 SRP patients: 1 superior mesenteric artery syndrome, 1 bowel obstruction vs 0 ERP patients, p = 0.23). CONCLUSION: In this cohort, minor changes to the postoperative protocol following surgery for AIS led to a significant decrease in hospital length of stay. This minimalistic approach may ease implementation of an ERP in the setting of stakeholder apprehension.

RESUMO

The COVID-19 pandemic has had a profound and robust impact on individuals' lives and has particularly negatively affected individuals' experiences with fear of catching COVID-19. To measure this fear, researchers created the unidimensional Fear of COVID-19 Scale (FCV-19S). However, some exploratory factor analysis studies suggested the presence of two factors, which are 1) emotional fear and 2) physiological expressions of fear. In the current exploratory study, we aimed to confirm this factor structure using confirmatory factor analysis and to examine how these two new factors of the FCV-19S explain variability in the impacts of COVID-19 on nine life domains (i.e., finances, loved ones, job, safety, school, mental health, physical health, social activities, and quality of life). Participants were undergraduate students (n = 224) from a Midwestern University (White: 60.7%; Male: 48.0%) who participated in the study for course credit. The results revealed that the two-factor model had an excellent fit for the FCV-19S, both subscales had excellent psychometric properties, and the emotional fear subscale significantly explained variability in all nine life domains (7% to 54%). However, the physiological fear subscale only significantly explained variability in the physical health domain along with emotional fear (28%). The findings suggested that emotional fear of COVID-19 may explain more variability in the impact of COVID-19 across life domains, while physiological fear may only explain the effects of COVID-19 on physical health. We further discussed implications, limitations, and future directions.

RESUMO

Researcher degrees of freedom can affect the results of hypothesis tests and consequently, the conclusions drawn from the data. Previous research has documented variability in accuracy, speed, and documentation of output across various statistical software packages. In the current investigation, we conducted Pearson's chi-square test of independence, Spearman's rank-ordered correlation, Kruskal-Wallis one-way analysis of variance, Wilcoxon Mann-Whitney U rank-sum tests, and Wilcoxon signed-rank tests, along with estimates of skewness and kurtosis, on large, medium, and small samples of real and simulated data in SPSS, SAS, Stata, and R and compared the results with those obtained through hand calculation using the raw computational formulas. Multiple inconsistencies were found in the results produced between statistical packages due to algorithmic variation, computational error, and statistical output. The most notable inconsistencies were due to algorithmic variations in the computation of Pearson's chi-square test conducted on 2 × 2 tables, where differences in p-values reported by different software packages ranged from .005 to .162, largely as a function of sample size. We discuss how such inconsistencies may influence the conclusions drawn from the results of statistical analyses depending on the statistical software used, and we urge researchers to analyze their data across multiple packages to check for inconsistencies and report details regarding the statistical procedure used for data analysis.

RESUMO

Background: Biomechanical studies support the use of suture tape reinforcement for limiting graft elongation and increasing strength in knee ligament reconstructions. Purpose: To compare posterior cruciate ligament (PCL) laxity, complication and reoperation rates, and patient-reported outcomes (PROs) after all-inside single-bundle PCL reconstruction (PCLR) with versus without independent suture tape reinforcement. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective cohort study of consecutive patients who underwent primary, all-inside allograft single-bundle PCLR with and without independent suture tape reinforcement at a single academic institution from 2012 to 2019. Medical records were reviewed for patient characteristics, additional injuries, and concomitant procedures. PRO scores (including the International Knee Documentation Committee [IKDC], Tegner activity scale, and Lysholm scores), bilateral comparison kneeling radiographs, and physical examination findings were collected at a minimum of 2 years postoperatively. Results: Included were 50 patients: 19 with suture tape reinforcement (mean age 30.6 ± 2.9 years) and 31 without suture tape reinforcement (control group; mean age 26.2 ± 1.6 years). One PCLR graft in the suture tape group failed. Posterior drawer examination revealed grade 1+ laxity in 4 of 19 (21%) of the suture tape cohort versus 6 of 31 (19%) of the control cohort (P > .999). Bilateral kneeling radiographs showed similar side-to-side differences in laxity between the groups (suture tape vs control: mean, 1.9 ± 0.4 vs 2.6 ± 0.6 mm; P = .361). There were no statistically significant differences between the groups in postoperative IKDC (suture tape vs control: 79.3 vs 79.6; P = .779), Lysholm (87.5 vs 84.3; P = .828), or Tegner activity (5.6 vs 5.7; P = .562) scores. Conclusion: All-inside single-bundle PCLR with and without independent suture tape reinforcement demonstrated low rates of graft failure, complications, and reoperations, with satisfactory PROs at a minimum 2-year follow-up. Radiographic posterior tibial translation was comparable between the 2 groups.

RESUMO

The ecotoxicity of biosolids has been studied extensively using single-compound toxicity testing and 'spiking' studies; however, little knowledge exists on the ecotoxicity of biosolids as they are land-applied in the Canadian context. The purpose of this study is to elucidate the chronic, sub-lethal (i.e., behavioural), and lethal impacts of land- applying biosolids on the environmentally relevant Folsomia candida (springtails) and Lumbricus terrestris (earthworms) and concomitantly ascertain whether the use of biosolids for nutrient amendment is a sustainable practice. This study is part of a larger multi-compartment programme which includes terrestrial plants and aquatic arthropods. After a review of existing government protocols and research, the current study suggests new environmentally relevant bioassays as to elucidate the true nature of the potential ecotoxicity of land-applying biosolids, within a laboratory context. Specifically, protocols were developed (e.g., shoebox bioassays for L. terrestris sub-lethal testing) or modified (e.g., using Evans' boxes (Evans 1947) for chronic and sub-lethal testing on L. terrestris). Subsequently, two biosolids were tested on springtails and earthworms using avoidance and reproductive bioassay endpoints, at application rates that represent standard (8 tonnes ha-1) and worst-case scenarios (22 tonnes ha-1). Results indicated no effect of biosolids at the environmentally relevant concentration; the worst-case scenario exhibited a positive significantly significant relationship (indicating preference for treatment conditions). We suggest that further assessment of the potential ecotoxicological impact of biosolids employ (i) environmentally relevant organisms, (ii) appropriate bioassays including the use of whole-organism endpoints, and (iii) multi-kingdom testing (e.g., Kingdom Plantae, Animalia) to comprehensively elucidate answers. Lastly, in situ (field assays) are strongly encouraged for future studies.

RESUMO

After working in the substance use field for several years and conducting research on substance use, it has come to my attention how deeply ingrained the War on Drugs propaganda is in substance use research. The lines of research demonstrating the potential benefits of substance use (including illicit substances), delineation of harm from stigma, and the societal impact of the War on Drugs is rather weak and lacking, despite numerous recent studies showing the benefits of certain substances and reports of individuals in therapy and online suggesing that illicit substances help them in some respects. There are numerous critical implications of this bias in substance use research. Suppose the field primarily produces studies that show that all substances are harmful in almost any circumstance and that substance use disorders (SUDs) are primarily driven by psychological deficits (e.g., willpower). In that case, we, as researchers, would be feeding into the War on Drugs, which is known for marginalizing individuals, promoting organized crime, exacerbating SUDs, feeding into a police and prison state, and killing individuals due to tainted substances. Substance use researchers and clinicians are among the first to recognize that the War on Drugs has failed. Yet, despite this belief, we seem to have not quite fully noticed how the propaganda has influenced how we conduct our jobs and the research we produce. In the current letter, I inform researchers who study substance use and clinicians who treat SUDs to acknowledge their own learned biases against substances and those who use substances; to be more cautious when interpreting substance use data in the future.
