Long-Term Mental Health Effects of a Devastating Wildfire Are Amplified by Sociodemographic and Clinical Antecedents in College Students.

OBJECTIVES: The aim of this study is to assess prevalence of major depressive disorder (MDD), generalized anxiety disorder (GAD), and posttraumatic stress disorder (PTSD) in students of Keyano College 18 months after a wildfire and to determine the predictors of likely MDD, GAD, and PTSD in the respondents. METHODS: A quantitative cross-sectional survey was used to collect data through self-administered, paper-based questionnaires to determine likely MDD, GAD, and PTSD using the PHQ 9, GAD-7, and the PTSD Checklist for DSM 5, Part 3, respectively. Data were analyzed with SPSS version 20 (IBM Corp, Armonk, NY) using univariate analysis with chi-square tests. RESULTS: Eighteen months after the wildfire, the 1-month prevalence rates for MDD, GAD, and PTSD among the college students were 23.4%, 18.7%, and 11.0%, respectively. There were statistically significant associations between multiple sociodemographic variables and the likelihood respondents presented with MDD, GAD, and PTSD 18 months after the wildfire. There were also associations between the likely MDD, GAD, and PTSD and abuse/dependence on alcohol and substances in respondents at 18 months. CONCLUSION: Our study has established prevalence rates for MDD, GAD, and PTDS among college students 18 months after the Fort McMurray wildfires. Further studies are needed to explore the impact of college-based mental health interventions on the long-term mental health effects of the wildfires.

Long-Term Mental Health Effects of a Devastating Wildfire Are Amplified by Socio-Demographic and Clinical Antecedents in Elementary and High School Staff.

OBJECTIVES: To assess the likely prevalence rates of Major Depressive Disorder (MDD), Generalized Anxiety Disorder (GAD) and Post-Traumatic Stress Disorder (PTSD) in staff of Fort McMurray School Districts eighteen months after a May 2016 wildfire, and to determine possible predictors. METHODS: A quantitative cross-sectional survey was used to collect data through self-administered online questionnaires to determine likely MDD, GAD and PTSD using well validated self-report questionnaires. RESULTS: Of 1,446 staff who were sent the online survey link in an e-mail, 197 completed the survey, of which there were 168 females (85%) and 29 males (15%). The one-month prevalence rates for likely MDD, GAD and PTSD among the school staff were 18.3, 15.7 and 10.2% respectively. There were statistically significant associations between multiple socio-demographic and clinical variables likely MDD, GAD and PTSD among respondents. CONCLUSION: Knowledge of key factors for MDD, GAD and PTSD may be helpful for policy makers when formulating population level social and clinical programs, to mitigate the mental health effects of future natural disasters.

Mental Health Effects in Primary Care Patients 18 Months After a Major Wildfire in Fort McMurray: Risk Increased by Social Demographic Issues, Clinical Antecedents, and Degree of Fire Exposure.

Objectives: To assess prevalence of likely posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and generalized anxiety disorder (GAD) in patients attending the only out-of-hours primary care clinic in Fort McMurray some 18 months following a major fire. Methods: A quantitative cross-sectional survey was used to collect data through self-administered paper-based questionnaires to determine likely PTSD, MDD, and GAD using the PTSD Checklists for Diagnostic and Statistical Manual (DSM) 5, Patient Health Questionnaire (PHQ) 9, and GAD-7, respectively, from residents of Fort McMurray who were impacted by the wildfires. This was carried out eighteen (18) months after a major wildfire, which required the rapid evacuation of the entire city population (approximately 90,000 individuals). Results: We achieved a response rate of 48% and results from the 290 respondents showed the 1 month prevalence rate for likely PTSD was 13.6%, likely MDD was 24.8%, and likely GAD was 18.0%. Compared to self-reported prevalence rates before the wildfire (0%, 15.2%, and 14.5% respectively), these were increased for all diagnoses. After controlling for other factors in a logistic regression model, there were statistically significant associations between individuals who had likely PTSD, MDD, and GAD diagnoses and multiple socio-demographic, clinical, and exposure-related variables as follows: PTSD: History of anxiety disorder and received counselling had odds ratios (ORs) of 5.80 and 7.14, respectively. MDD: Age, witnessed the burning of homes, history of depressive disorder, and receiving low level support from friends and family had ORs of 2.08, 2.29, 4.63, and 2.5, respectively. GAD: Fearful for their lives or the lives of friends/family, history of depressive disorder, and history of anxiety disorder had ORs of 3.52, 3.04, and 2.68, respectively. There were also associations between individuals with a likely psychiatric diagnosis and those who also had likely alcohol or drug abuse/dependence. Conclusion: Our study suggests there are high prevalence rates for mental health and addiction conditions in patients attending the out-of-hours clinic 18 months after the wildfires, with significant associations between multiple variables and likely PTSD, MDD, and GAD. Further studies are needed to explore the impact of population-based mental health interventions on the long-term mental health effects of the wildfires.

Prevalence Rates and Predictors of Generalized Anxiety Disorder Symptoms in Residents of Fort McMurray Six Months After a Wildfire.

The Fort McMurray wildfire was the costliest disaster in Canadian history, with far-reaching impacts. The purpose of this paper is to examine the prevalence and risk factors of elevated generalized anxiety disorder (GAD) symptomatology in residents of Fort McMurray 6 months after the wildfire. Data were collected via random selection procedures from 486 participants. Generalized anxiety disorder symptoms were measured via the GAD-7. The 1-month prevalence rate for GAD symptomatology 6 months after the disaster was 19.8% overall, regression analyses revealed six variables with significant unique contributions to prediction of GAD symptomatology. Significant predictors were: pre-existing anxiety disorder, witnessing of homes being destroyed by the wildfire, living in a different home after the wildfire, receiving limited governmental support or limited family support, and receiving counseling after the wildfire. Participants with these risk factors were between two to nearly seven times more likely to present with GAD symptomatology. In addition, participants who presented with elevated symptomatology were more likely to increase use or problematically use substances post-disaster. This study extends the literature on mental health conditions and risk factors following disasters, specifically in the area of generalized anxiety. Findings and implications are discussed.

Modeling, synthesis and biological evaluation of potential retinoid X receptor (RXR) selective agonists: novel analogues of 4-[1-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydro-2-naphthyl)ethynyl]benzoic acid (bexarotene).

This report describes the synthesis of analogues of 4-[1-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydro-2-naphthyl)ethynyl]benzoic acid (1), commonly known as bexarotene, and their analysis in acting as retinoid X receptor (RXR)-specific agonists. Compound 1 has FDA approval to treat cutaneous T-cell lymphoma (CTCL); however, its use can cause side effects such as hypothyroidism and increased triglyceride concentrations, presumably by disruption of RXR heterodimerization with other nuclear receptors. The novel analogues in the present study have been evaluated for RXR activation in an RXR mammalian-2-hybrid assay as well as an RXRE-mediated transcriptional assay and for their ability to induce apoptosis as well as for their mutagenicity and cytotoxicity. Analysis of 11 novel compounds revealed the discovery of three analogues that best induce RXR-mediated transcriptional activity, stimulate apoptosis, have comparable K(i) and EC(50) values to 1, and are selective RXR agonists. Our experimental approach suggests that rational drug design can develop new rexinoids with improved biological properties.

Evolution of endoscopic management of ectopic ureterocele: a new approach.

PURPOSE: We report the evolution of endoscopic treatment of ectopic ureteroceles from the unroofing technique to a novel approach using concomitant ureterocele double puncture and intraureterocele fulguration. We also compare the results of different endoscopic modalities at a single center. MATERIALS AND METHODS: We reviewed the records of 46 children with ectopic ureteroceles who were treated endoscopically between 1995 and 2005. The patients were divided into 2 main groups. Group 1 included 17 patients who underwent common endoscopic treatments, including ureterocele incision (4 patients), single ureterocele puncture (4), and single puncture with insertion of a Double-J stent (9). Group 2 included 29 children who underwent ureterocele double puncture and fulguration of the anterior and posterior walls of the collapsed ureterocele after insertion of a Double-J stent into both punctured sites. We also managed concomitant vesicoureteral reflux by endoscopic injection of tricalcium phosphate ceramic into the subureteral region. RESULTS: Total success rates in group 1 were 0%, 25% and 33% in patients who underwent ureterocele incision, single ureterocele puncture and single puncture with insertion of a stent, respectively. Total success rate in group 2 was 90% (p<0.05). New onset vesicoureteral reflux developed in 8 patients (47%) in group 1, of which 6 were in ureterocele moieties, and in 8 patients (28%) in group 2, with none in a ureterocele moiety (p<0.01). A total of 13 patients (76%) in group 1 required open surgical intervention, compared to 3 (10%) in group 2 (p<0.05). CONCLUSIONS: This new endoscopic approach is highly effective in the treatment of children with ectopic ureteroceles.

Intravesical injection of botulinum toxin type A: management of neuropathic bladder and bowel dysfunction in children with myelomeningocele.

OBJECTIVES: To evaluate the efficacy of botulinum toxin A in the treatment of children with detrusor hyperreflexia caused by myelomeningocele and the effects of this treatment on neuropathic bladder and bowel dysfunction. METHODS: In a prospective study, 26 children with myelomeningocele (20 boys and 6 girls, mean age 6.9 years) were included. All patients had been nonresponders to medical treatment and required clean intermittent catheterization. Under cystoscopic guidance, 10 IU/kg of botulinum toxin A was injected into the detrusor muscle, sparing the trigone and ureteral orifices. In each patient, urinary incontinence grade and improvement in parameters of interest in the evaluation of bowel dysfunction were assessed before and 4 months after injection. Conventional urodynamic studies to determine maximal bladder capacity and maximal detrusor pressure and voiding cystoureterography were also performed. RESULTS: Four months after procedure, 19 patients (73%) had become completely dry between clean intermittent catheterizations, and the total improvement in urine incontinence was 88%. The mean maximal detrusor pressure was decreased to 83.2 +/- 4.6 cm H2O from the baseline of 139.3 +/- 11.2 (P <0.01). The average maximal bladder capacity increased from 102.8 +/- 6.3 mL to 270.2 +/- 9.5 mL (P <0.01). Of the 15 patients who had varying degrees of vesicoureteral reflux before the procedure, 11 (73%) had decrease in the vesicoureteral reflux grade. Also, bowel dysfunction improved in 10 (66%) of the 15 patients. CONCLUSIONS: Botulinum toxin A appears to be a safe, minimally invasive procedure for the management of neuropathic bladder and bowel dysfunction in children with myelomeningocele.

Suprapubic prostatectomy with a novel catheter.

PURPOSE: We evaluated the postoperative morbidity and technical complications of a new handmade catheter used for suprapubic prostatectomy. MATERIALS AND METHODS: A total of 146 patients with lower urinary tract symptoms who had indications for open prostatectomy were enrolled in the study from January 2003 to August 2004. Of the patients 96 were treated with a novel technique without a urethral catheter but with a special handmade cystostomy catheter, while the other 50 underwent the traditional procedure using cystostomy and a urethral catheter. The same surgical team operated on the 2 groups. Clot retention episodes, hemoglobin decreases, irritative symptoms, voiding status after cystostomy removal and incontinence were evaluated postoperatively. Three months later we followed the patients with symptom score, maximum flow rate and cystoscopic examination. RESULTS: Preoperatively mean International Prostate Symptom Score was 31.6 in each group. Postoperatively none of the patients with the novel catheter complained of significant irritative urinary symptoms, clot retention and true or stress urinary incontinence. Of the cohorts 94% were satisfied with voiding but 86% of controls were satisfied. There was no report of urinary tract infection or epididymo-orchitis in the cohorts, while we found epididymo-orchitis in 4 controls (8%). Three months after the operation the mean International Prostate Symptom Score was 4.4 (range 1 to 7) and the mean maximum flow rate was 22.6 ml per second (range 14 to 25) in patients with the novel catheter, and 4.2 (range 1 to 7) and 22.5 ml per second (range 15 to 25), respectively, in those with the traditional catheter. At followup there was no bladder neck contracture but 4 patients (4.1%) showed some degree of membranous urethral stricture. We also noted 7 controls (14%) with urethral stricture. CONCLUSIONS: Transurethral prostate resection has been introduced as the surgical treatment of choice in patients with benign prostatic hyperplasia. However, open adenomectomy still has a place. Urethral catheter-free suprapubic prostatectomy can be safely applied with a low postoperative risk of infection, incontinence and stricture formation.

Posttransplant infectious complications: a prospective study on 142 kidney allograft recipients.

INTRODUCTION: We evaluated the posttransplant complications resulting from infections and their association with graft function, immunosuppressive drugs, and mortality. MATERIALS AND METHODS: A total of 142 kidney allograft recipients were followed for 1 year after transplantation. The patients' status was assessed during regular visits, and data including clinical characteristics, infections, serum creatinine level, acute rejection episodes, immunosuppressive regimen, graft function, and mortality were recorded and analyzed. RESULTS: Infections occurred in 77 patients (54%). The lower urinary (42%) and respiratory (6.3%) tracts were the most common sites of infection. The most frequent causative organisms were Klebsiella in 34 (24%) and cytomegalovirus in 25 patients (18%). Wound infection occurred in 7 patients (5%). The mortality rate was 7.7% and infection-related death was seen in 5 patients (3.5%) who developed sepsis. Graft loss was seen in 16 patients (11%), of whom 2 developed cytomegalovirus infection, 2 experienced urinary tract infection, and 5 developed sepsis and died. Mycobacterial and hepatitis C infections were noticeably rare (0.7% and 2.8%, respectively). CONCLUSION: This study showed that infections are important causes of morbidity and mortality during the posttransplant period. We recommend that serologic tests be performed before and after transplantation to recognize and meticulously follow those who are at risk. In our study, high-risk patients were those with elevated serum creatinine levels who received high doses of immunosuppressive drugs. As the urinary tract is the most common site of infection, early removal of urethral catheter is recommended to reduce the risk of infection.
