Survey of occupational hygiene professional practice in Spanish-speaking countries.

Professional credentialing schemes based on experience and examination are used to clarify the scope and required competencies associated with the practice of a profession. National occupational hygiene (OH) credentials developed in 17 nations have been recognized by the International Occupational Hygiene Association (IOHA) to meet or exceed the requirements of a model certification program. To date, there is no credentialing or certification scheme for occupational hygienists in Spanish-speaking regions. To fill this void, a new credentialing body has been created named the Iberoamerican Board of Occupational Hygiene (JIHO). As a first step to the development of a certification exam for a profession, it is necessary to determine the interest in an occupational hygiene certification exam in Spanish and to clarify the most common work practices for those practicing the profession. To determine the proper exam weightings for occupational hygiene competencies needed to practice in Spanish-speaking regions JIHO conducted a comprehensive survey of professional practice of occupational hygiene in nations where Spanish is spoken as the primary language. Surveys were sent to 456 practicing occupational hygienists in nine different countries on a variety of topics. Results indicated that 79% of respondents felt the need for an OH certification exam in Spanish was very or extremely important. The most frequent and important technical competencies utilized in practice were (1) awareness about the health effects of hazardous agents to make decisions about workplace activities and exposures, (2) application of the hierarchy of controls, control banding, hazard communication, training of employees and other methods to reduce worker exposure and workplace risks, and (3) application of principles to recognize and control biohazards in the workplace. The study results have been used to guide the weighting and importance of various technical topics and rubrics on the JIHO exam. Data from this study can be used in the development of certification examinations, to improve international coherence in the profession, and the development of educational programs in OH.

A genome-wide cytotoxicity screen of cluster F1 mycobacteriophage Girr reveals novel inhibitors of Mycobacterium smegmatis growth.

Over the past decade, thousands of bacteriophage genomes have been sequenced and annotated. A striking observation from this work is that known structural features and functions cannot be assigned for >65% of the encoded proteins. One approach to begin experimentally elucidating the function of these uncharacterized gene products is genome-wide screening to identify phage genes that confer phenotypes of interest like inhibition of host growth. This study describes the results of a screen evaluating the effects of overexpressing each gene encoded by the temperate Cluster F1 mycobacteriophage Girr on the growth of the host bacterium Mycobacterium smegmatis. Overexpression of 29 of the 102 Girr genes (~28% of the genome) resulted in mild to severe cytotoxicity. Of the 29 toxic genes described, 12 have no known function and are predominately small proteins of <125 amino acids. Overexpression of the majority of these 12 cytotoxic no known functions proteins resulted in moderate to severe growth reduction and represent novel antimicrobial products. The remaining 17 toxic genes have predicted functions, encoding products involved in phage structure, DNA replication/modification, DNA binding/gene regulation, or other enzymatic activity. Comparison of this dataset with prior genome-wide cytotoxicity screens of mycobacteriophages Waterfoul and Hammy reveals some common functional themes, though several of the predicted Girr functions associated with cytotoxicity in our report, including genes involved in lysogeny, have not been described previously. This study, completed as part of the HHMI-supported SEA-GENES project, highlights the power of parallel, genome-wide overexpression screens to identify novel interactions between phages and their hosts.

Female pelvic medicine and reconstructive surgery fellows' case logs remained stable during the COVID-19 pandemic.

INTRODUCTION: During the COVID-19 pandemic and subsequent staffing shortages there was concern about the case volume, and thus competency, of graduating trainees due to reduced surgical volumes. Elective procedures were particularly affected, which includes Female Pelvic Medicine and Reconstructive Surgery (FPMRS) cases. To understand whether FPMRS fellows were affected, we assessed their case logs for changes during the pandemic. METHODS: The nationally aggregated case logs of graduating FPMRS fellows, both urology and obstetrics and gynecology (OBGYN), were obtained from the Accreditation Council for Graduate Medical Education. The available academic years (AYs) included 2018-2019, 2019-2020, and 2020-2021. Standard deviation for each index category was derived from the average and 90th percentile data. One-way analysis of variance was used to compare differences in case volumes for tracked index categories between AYs. RESULTS: Graduating fellows logged an average of 517.4 (standard deviation [SD] 28.6) and 818.0 (SD 37.9) cases, for urology and OBGYN respectively, over their fellowship training during the examined period. No significant differences in total surgical procedures were found for either specialty between pre-COVID AY 2018-2019 and COVID-affected AYs 2019-2020 and 2020-2021. For urology fellows, gastrointestinal (GI) procedures was the only index case category with a significant difference, and it was a decrease between the two COVID-affected AYs: 2020-2021 compared to 2019-2020 (8.9 vs. 4.2, p = 0.04). For both urology and OBGYN fellows, there was a statistically significant decrease in graft/mesh augmentation procedures from COVID-affected AY 2019-2020 to AY 2020-2021. This may be attributed to the reclassification of mesh removal cases from graft/mesh augmentation procedures to genital procedures in 2020-2021. There was not a significant decrease in these procedures from pre-COVID AY 2018-2019 to the COVID-affected AYs. There were no other statistically significant differences between AYs for OBGYN fellows. CONCLUSIONS: Surgical case volumes for FPMRS urology and OBGYN fellows who trained during the COVID-19 pandemic were comparable to those of their pre-pandemic peers. No significant differences between pre-COVID and COVID-affected years were found for either total surgical procedures or index case categories. Despite disruptions in health care nationwide, FPMRS trainee case volumes were largely unaffected.

Survey evidence on COVID-19 and its impact on rail commuting patterns in Great Britain.

The COVID-19 pandemic saw a large proportion of the working population in the United Kingdom working from home for an extend period of time. In September 2021, a substantial number continued to work from home on a regular basis, a stark contrast to the situation pre-pandemic. Prior to 2020, although there was a growing trend for increased home working, this was still not a widespread practice across UK businesses, with the majority of staff working full-time from the employment location. The aim of this paper is to report the main changes in commuting and working patterns among commuters in Great Britain (GB) brought about by the COVID-19 pandemic with a special emphasis on the rail commuting market. The paper is informed by a panel survey of 3,892 GB respondents who commuted regularly to work prior to the pandemic in two waves. The first wave was conducted in Summer 2020 and focused on respondents' pre-pandemic travel patterns. The second wave was conducted in the Autumn 2021 and asked respondents about their current travel patterns. Although the focus was on rail travel, many of the conclusions of this paper are applicable to all modes of transport. Although a majority of pre-pandemic commuters have returned to commuting at least once per week to their place of work, there is a significant share of pre-pandemic commuters who are still working from home full-time. The return to the workplace has been slower among individuals who used to commute by rail compared to other modes. This is partially explained by current workplace arrangements being strongly linked with an individual's occupation and mode of transport. Individuals in office-based occupations are much more likely to work from home compared to those who work in other occupations. The pandemic has brought additional challenges to transport systems in addition to the reduced ridership level. Some of the emerging issues include managing post-pandemic peak travel volumes across a curtailed working week and the associated funding for peak capacity. Nonetheless, the research has highlighted some potential strategies to boost a faster recovery for travel demand.

Better Together. Group versus individual Cognitive-Behavioral Therapy for tinnitus: A Multiple-Baseline Single-Case Experimental Design.

OBJECTIVES: Chronic tinnitus is effectively treated through cognitive-behavioral therapy (CBT). Both group and individual CBT for tinnitus are effective, but no study has directly compared the two. The current study explores group versus individual CBT for tinnitus. DESIGN: A multiple-baseline single-case experimental design was employed to observe changes within/between individual and group treatments. Six participants started a 10-week CBT protocol and were equally divided into individual or group treatment. Participants were exchanged between treatments at random time points. Diary data included 14 variables on tinnitus experience (e.g. annoyance and distraction) and wellbeing (e.g. happiness and stress). Five male participants (59- to 67-year-old) completed treatment. RESULTS: Randomization tests comparing means between individual and group treatments did not reveal significant differences. Analysis of data overlap and trend (Tau-U) revealed minor significant improvements for seven variables (50%) in group treatment as compared to individual treatment. Diminished happiness and activity levels were observed in participants who went from group to individual treatment. CONCLUSIONS: Low effect sizes and homogeneity of sample restrict the generalizability of data. Group CBT indicated potential benefits when compared to individual CBT. Social learning may be an underlying process in group delivery boosting tinnitus recovery. Findings are limited to male patients with chronic disabling tinnitus.

Fear influences phantom sound percepts in an anechoic room.

Aims and hypotheses: In an environment of absolute silence, researchers have found many of their participants to perceive phantom sounds (tinnitus). With this between-subject experiment, we aimed to elaborate on these research findings, and specifically investigated whether-in line with the fear-avoidance model of tinnitus perception and reactivity-fear or level of perceived threat influences the incidence and perceptual qualities of phantom sound percepts in an anechoic room. We investigated the potential role of individual differences in anxiety, negative affect, noise sensitivity and subclinical hearing loss. We hypothesized that participants who experience a higher level of threat would direct their attention more to the auditory system, leading to the perception of tinnitus-like sounds, which would otherwise be subaudible, and that under conditions of increased threat, narrowing of attention would lead to perceptual distortions. Methods: In total, N = 78 normal-hearing volunteers participated in this study. In general, the study sample consisted of young, mostly female, university students. Their hearing was evaluated using gold-standard pure tone audiometry and a speech-in-noise self-test (Digit Triplet Test), which is a sensitive screening test to identify subclinical hearing loss. Prior to a four-minute stay in an anechoic room, we randomized participants block design-wise in a threat (N = 37) and no-threat condition (N = 41). Participants in the threat condition were deceived about their hearing and were led to believe that staying in the room would potentially harm their hearing temporarily. Participants were asked whether they perceived sounds during their stay in the room and rated the perceptual qualities of sound percepts (loudness and unpleasantness). They were also asked to fill-out standardized questionnaires measuring anxiety (State-Trait Anxiety Inventory), affect (Positive and Negative Affect Schedule) and noise sensitivity (Weinstein Noise Sensitivity Scale). The internal consistency of the questionnaires used was verified in our study sample and ranged between α = 0.61 and α = 0.90. Results: In line with incidence rates reported in the literature, 74% of our participants reported having heard tinnitus-like sounds in the anechoic room. Speech-in-noise identification ability was comparable for both groups of participants. The experimental manipulation of threat was proven to be effective, as indicated by significantly higher scores on a Threat Manipulation Checklist among participants in the threat condition as compared to those in the no-threat condition (p < 0.01). Nevertheless, participants in the threat condition were as likely to report tinnitus percepts as participants in the no-threat condition (p = 1), and tinnitus percepts were not rated as being louder (p = 0.76) or more unpleasant (p = 0.64) as a function of level of threat. For participants who did experience tinnitus percepts, a higher level of threat was associated with a higher degree of experienced unpleasantness (p < 0.01). These associations were absent in those who did not experience tinnitus. Higher negative affect was only slightly associated with higher ratings of tinnitus unpleasantness (p < 0.01). Conclusion: Whereas our threat manipulation was successful in elevating the level of fear, it did not contribute to a higher percentage of participants perceiving tinnitus-like sounds in the threat condition. However, higher levels of perceived threat were related to a higher degree of perceived tinnitus unpleasantness. The findings of our study are drawn from a rather homogenous participant pool in terms of age, gender, and educational background, challenging conclusions that are applicable for the general population. Participants generally obtained normophoric scores on independent variables of interest: they were low anxious, low noise-sensitive, and there was little evidence for the presence of subclinical hearing loss. Possibly, there was insufficient variation in scores to find effects.

Honing-in antigen-specific cells during antibody discovery: a user-friendly process to mine a deeper repertoire.

Immunization based antibody discovery is plagued by the paucity of antigen-specific B cells. Identifying these cells is akin to finding needle in a haystack. Current and emerging technologies while effective, are limited in terms of capturing the antigen-specific repertoire. We report on the bulk purification of antigen-specific B-cells and the benefits it offers to various antibody discovery platforms. Using five different antigens, we show hit rates of 51-88%, compared to about 5% with conventional methods. We also show that this purification is highly efficient with loss of only about 2% antigen specific cells. Furthermore, we compared clones in which cognate chains are preserved with those from display libraries in which chains either from total B cells (TBC) or antigen-specific B cells (AgSC) underwent combinatorial pairing. We found that cognate chain paired clones and combinatorial clones from AgSC library had higher frequency of functional clones and showed greater diversity in sequence and paratope compared to clones from the TBC library. This antigen-specific B-cell selection technique exemplifies a process improvement with reduced cycle time and cost, by removing undesired clones prior to screening and increasing the chance of capturing desirable and rare functional clones in the repertoire.

Robotic Ureteral Reconstruction.

It is generally accepted that robotic ureteral reconstruction provides equivalent results to open and laparoscopic approaches while decreasing pain and length of stay. There is a rapid expansion of robotic ureteral reconstructive techniques, platforms, and adjunctive technologies, enabling more efficient, safer, and novel surgical approaches that could not be done in the past. For instance, indocyanine green use allows rapid, precise location of ureteral stenosis and determination of tissue perfusion. Multi-image display allows the surgeon to integrate the robotic field and ureteroscopic images. Novel robotic surgical techniques, such as buccal mucosa ureteroplasty, are changing the treatment algorithm for ureteral strictures.

Outcomes of Initial Transcorporal Versus Standard Placement of Artificial Urinary Sphincter in Patients With Prior Radiation.

OBJECTIVE: This study aimed to evaluate both device and functional outcomes of men who underwent initial artificial urinary sphincter (AUS) placement after pelvic radiation using the transcorporal versus the standard approach. METHODS: A retrospective review of patients who underwent first-time AUS placement after pelvic irradiation for prostate cancer was conducted between January 2008 and June 2020. Patients were grouped by transcorporal versus standard device placement. The primary outcomes of interest included major complications (revision or explant surgery) and functional outcomes (pads per day, International Prostate Symptom Score {IPSS}, quality of life {QOL} score). RESULTS: We identified 45 patients who underwent first-time AUS with a history of prior pelvic irradiation for prostate cancer, 27 underwent transcorporal placement and 18 underwent standard placement. Transcorporal AUS placement resulted in a significantly lower number of major complications (p=0.01), explants (p=0.02), and revisions (p=0.04) The transcorporal artificial urinary sphincter group had better postoperative pads per day (p=0.04), IPSS (p<0.01), and IPSS QOL score (p<0.01). CONCLUSIONS: Initial transcorporal artificial urinary sphincter placement is a promising technique with lower rates of major complications in patients with a history of prior pelvic radiation and had better functional urinary outcomes.

Effect of COVID-19 on Graduating Urology Resident Case Logs: Analysis of the Accreditation Council of Graduate Medical Education National Data Reports.

OBJECTIVE: To assess the national case logs of the first graduating urologic resident cohorts to have trained during the COVID-19 pandemic for effects on surgical volumes. METHODS: The nationally aggregated Accreditation Council for Graduate Medical Education urology resident case logs were obtained for graduates of academic years (AYs) 2015-2016 through 2020-2021. Case volume differences for tracked index categories were compared between AYs with a 1-way analysis of variance. Data were then combined into pre-COVID and COVID-affected resident cohorts and differences in average cases logged were analyzed with 2-tailed student's t-tests. RESULTS: Graduating urology residents logged an average of 1322 (SD 24.8) cases over their residency during the examined period. Total cases had multiple statistical differences between AYs but the only index category with a statistically significant decrease for a COVID-affected AY compared to pre-COVID AY was pediatric majors: AY 2020-2021 logged fewer cases than AY 2015-2016 (53.9 vs 63.0, P = .004) and AY 2018-2019 (53.9 vs 61.2, P = .04). When aggregated into pre- and COVID-affected cohorts, both pediatric minor (123.4 vs 117.5, P = .049) and pediatric major (61.4 vs 56.8, P = .003) case averages decreased for the COVID-affected cohort of residents, but no adult index category decreased. CONCLUSION: National graduating urology resident surgical volume for adult index categories was maintained through the pandemic. Pediatric cases saw a statistical decrease in volume of questionable clinical significance. This does not eliminate concern that individuals may have experienced a detrimental impact on their resident education.

Pragmatic Uncontrolled Study of Specialized Cognitive Behavioral Therapy for Adults With Chronic Tinnitus.

OBJECTIVES: Tinnitus is the perception of sound without an external source, affecting quality of life that can cause severe distress in approximately 1 to 3% of the population of people with tinnitus. Randomized controlled trials of cognitive behavioral therapy for tinnitus have demonstrated its effectiveness in improving quality of life, but the effects of their implementation on a large scale in routine practice remains unknown. Therefore, the main purpose of this study was to examine the effects of stepped-care cognitive behavioral therapy for tinnitus delivered in a tertiary audiological center of a regional hospital. Second, we wished to examine predictors of favorable outcome. DESIGN: Four hundred three adults with chronic tinnitus were enrolled in this prospective observational study (at 3 months, N=334, 8 months, N=261; 12 months, N=214). The primary outcome was health-related quality of life as measured by the Health Utilities Index III (HUI-III) at 12 months. Secondary outcomes were self-reported levels of tinnitus-related distress, disability, affective distress and tinnitus-related negative beliefs and fear. Measures were completed pre-intervention at 3 months, 8 months, and 12 months. Multilevel modeling was used to examine effects and their predictors. RESULTS: Younger participants with lower levels of tinnitus distress were more likely to dropout while those with higher tinnitus distress at baseline and quality of life were more likely to receive step 2 of treatment. MLM analyses revealed, with one exception, no relation between any baseline variable and outcome change over time. Most participants' improvement exceeded minimally clinical important difference criteria for quality of life, tinnitus-related handicap, and tinnitus distress. CONCLUSIONS: Results from this large pragmatic study complements those from randomized controlled trials of cognitive behavioral therapy for chronic tinnitus distress and supports its implementation under "real-world" conditions.

A narcotic free pathway for postoperative pain following urethroplasty.

INTRODUCTION: In an effort to decrease physician contribution to the opioid crisis, we utilized a narcotic free pathway (NFP) after urethroplasty. Our objectives were to demonstrate feasibility of a NFP and identify patients at higher risk for requiring postoperative narcotics. MATERIALS AND METHODS: We implemented a NFP for patients undergoing urethroplasty. Pain was assessed using the Likert scale (1-10). Narcotic use was quantified using oral morphine equivalents (OMEs). RESULTS: Forty-six patients underwent urethroplasty following the NFP over a 7-month period. Fifteen patients were excluded, leaving 31 patients in the final analysis. Postintervention data was compared to 30 patients who underwent urethroplasty prior to implementation of the NFP. The groups had similar demographics except for a history of heroin abuse (0% preintervention, 12.9% postintervention, p = 0.04). Surgical characteristics were not statistically different aside from length of surgery (183.6 minutes preintervention, 145.5 minutes postintervention, p = 0.01). The mean [SD] perioperative OME use preintervention was 194.9 [151] mg, compared to 40.4 [111.9] mg postintervention (p < 0.001). Six patients postintervention were discharged with a narcotic prescription (mean 27.5 mg OME) compared to 26 patients preintervention (mean 76 mg OME) (p < 0.001). There was no difference in pain scores at any time interval. Patients with a history of chronic opioid use were more likely to require narcotics (OR 5.33, CI 1-28.44). CONCLUSIONS: The narcotic free pathway resulted in a dramatic reduction in narcotic prescriptions without a significant difference in postoperative pain scores. Opioid use can be minimized following urethral and perineal surgery.

VanLee has 164 predicted protein-coding genes and one tRNA. VanLee can infect Gordonia terrae with the same efficiency as G. rubripertincta.

Multicenter urethroplasty outcomes for urethral stricture disease for patients with neurogenic bladder or bladder dysfunction requiring clean intermittent catheterization.

BACKGROUND: Our objective is to better comprehend treatment considerations for urethral stricture disease (USD) in patients requiring long-term clean intermittent catheterization (CIC). Patient characteristics, surgical outcomes and complications are unknown in this population. METHODS: Six members of the Trauma and Urologic Reconstruction Network of Surgeons (TURNS) participated in a prospective (2009 to present) and retrospective (prior to 2009) database recording patient demographics, surgical approach and outcomes. We included all patients undergoing urethroplasty who perform CIC. Descriptive statistics were used to analyze results. RESULTS: A total of 37 patients with 39 strictures were included. Bladder dysfunction was characterized as detrusor failure in 35% and neurogenic etiology in 65%. Median stricture length was 3 cm (IQR: 1.5-5.5) with 28% repaired with dorsal onlay buccal mucosal graft, 26% excision and primary anastomosis, 8% dorsal inlay, 8% ventral and dorsal, 8% flap based 8% non-transecting and 15% other. Functional success was 90%: 4 patients required DVIU or dilation due to recurrence, with 2 of those ultimately requiring repeat urethroplasty. 86% of patients returned to CIC; no patients reported new pad use for urinary leakage after urethroplasty. During a median follow-up period of 3.1 years (IQR: 1.0-5.3), no patients underwent urinary diversion. CONCLUSIONS: Urethroplasty is suitable, safe and effective for patients dependent on CIC suffering from USD. The effect of continual CIC on long-term outcomes remains uncertain.

Tinnitus and tinnitus disorder: Theoretical and operational definitions (an international multidisciplinary proposal).

As for hypertension, chronic pain, epilepsy and other disorders with particular symptoms, a commonly accepted and unambiguous definition provides a common ground for researchers and clinicians to study and treat the problem. The WHO's ICD11 definition only mentions tinnitus as a nonspecific symptom of a hearing disorder, but not as a clinical entity in its own right, and the American Psychiatric Association's DSM-V doesn't mention tinnitus at all. Here we propose that the tinnitus without and with associated suffering should be differentiated by distinct terms: "Tinnitus" for the former and "Tinnitus Disorder" for the latter. The proposed definition then becomes "Tinnitus is the conscious awareness of a tonal or composite noise for which there is no identifiable corresponding external acoustic source, which becomes Tinnitus Disorder "when associated with emotional distress, cognitive dysfunction, and/or autonomic arousal, leading to behavioural changes and functional disability.". In other words "Tinnitus" describes the auditory or sensory component, whereas "Tinnitus Disorder" reflects the auditory component and the associated suffering. Whereas acute tinnitus may be a symptom secondary to a trauma or disease, chronic tinnitus may be considered a primary disorder in its own right. If adopted, this will advance the recognition of tinnitus disorder as a primary health condition in its own right. The capacity to measure the incidence, prevalence, and impact will help in identification of human, financial, and educational needs required to address acute tinnitus as a symptom but chronic tinnitus as a disorder.

Robotic Surgery for the Reconstruction of Transplant Ureteral Strictures.

OBJECTIVE: To demonstrate the feasibility and success of a robotic approach to reconstruction of ureterovesical anastomotic strictures in kidney transplants. MATERIALS AND METHODS: Between November 2017 and December 2019, a total of 5 patients with transplant ureteral stricture were identified and treated with robot assisted laparoscopic repair. All patients were confirmed to have ureteral stricture with a preoperative antegrade nephrostogram through their nephrostomy tube and cystogram. The patients demographics, ureteral characteristics, type of procedure, and outcomes are reported. RESULTS: All patients were diagnosed after evaluation for renal deterioration. The average age of the patients was 49 years old. The average stricture length was 2.5 cm, and the location was variable, though more commonly in the distal ureter. Three patients required a pyelo-vesicostomy, while 2 required a ureteroneocystostomy. The mean length of stay was 2.2 days. Average follow-up was 97 days, with all 5 patients having successful outcomes, no strictures or delayed leaks were identified. There were no wound infections or readmissions within 30 days. CONCLUSION: Though a complex repair, the robot-assisted approach to transplant ureter reconstruction using either an end to side neoureterocystotomy or direct pyelo-vesicotomy is technically feasible and successful. Given the many advantages inherent in comparison to an open approach, the robotic repair offers significant advantages to both the patient and the surgeon who is experienced with robotic surgery and reconstructive principles.

Cognitive behavioural therapy for tinnitus.

BACKGROUND: Tinnitus affects up to 21% of the adult population with an estimated 1% to 3% experiencing severe problems. Cognitive behavioural therapy (CBT) is a collection of psychological treatments based on the cognitive and behavioural traditions in psychology and often used to treat people suffering from tinnitus. OBJECTIVES: To assess the effects and safety of CBT for tinnitus in adults. SEARCH METHODS: The Cochrane ENT Information Specialist searched the ENT Trials Register; CENTRAL (2019, Issue 11); Ovid MEDLINE; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 25 November 2019. SELECTION CRITERIA: Randomised controlled trials (RCTs) of CBT versus no intervention, audiological care, tinnitus retraining therapy or any other active treatment in adult participants with tinnitus. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. Our primary outcomes were the impact of tinnitus on disease-specific quality of life and serious adverse effects. Our secondary outcomes were: depression, anxiety, general health-related quality of life, negatively biased interpretations of tinnitus and other adverse effects. We used GRADE to assess the certainty of evidence for each outcome. MAIN RESULTS: We included 28 studies (mostly from Europe) with a total of 2733 participants. All participants had had tinnitus for at least three months and their average age ranged from 43 to 70 years. The duration of the CBT ranged from 3 to 22 weeks and it was mostly conducted in hospitals or online. There were four comparisons and we were interested in outcomes at end of treatment, and 6 and 12 months follow-up. The results below only refer to outcomes at end of treatment due to an absence of evidence at the other follow-up time points. CBT versus no intervention/wait list control Fourteen studies compared CBT with no intervention/wait list control. For the primary outcome, CBT may reduce the impact of tinnitus on quality of life at treatment end (standardised mean difference (SMD) -0.56, 95% confidence interval (CI) -0.83 to -0.30; 10 studies; 537 participants; low certainty). Re-expressed as a score on the Tinnitus Handicap Inventory (THI; range 0 to 100) this is equivalent to a score 10.91 points lower in the CBT group, with an estimated minimal clinically important difference (MCID) for this scale being 7 points. Seven studies, rated as moderate certainty, either reported or informed us via personal communication about serious adverse effects. CBT probably results in little or no difference in adverse effects: six studies reported none and in one study one participant in the CBT condition worsened (risk ratio (RR) 3.00, 95% CI 0.13 to 69.87). For the secondary outcomes, CBT may result in a slight reduction in depression (SMD -0.34, 95% CI-0.60 to -0.08; 8 studies; 502 participants; low certainty). However, we are uncertain whether CBT reduces anxiety, improves health-related quality of life or reduces negatively biased interpretations of tinnitus (all very low certainty). From seven studies, no other adverse effects were reported (moderate certainty). CBT versus audiological care Three studies compared CBT with audiological care. CBT probably reduces the impact of tinnitus on quality of life when compared with audiological care as measured by the THI (range 0 to 100; mean difference (MD) -5.65, 95% CI -9.79 to -1.50; 3 studies; 444 participants) (moderate certainty; MCID = 7 points). No serious adverse effects occurred in the two included studies reporting these, thus risk ratios were not calculated (moderate certainty). The evidence suggests that CBT may slightly reduce depression but may result in little or no difference in anxiety or health-related quality of life (all low certainty) when compared with audiological care. CBT may reduce negatively biased interpretations of tinnitus when compared with audiological care (low certainty). No other adverse effects were reported for either group (moderate certainty). CBT versus tinnitus retraining therapy (TRT) One study compared CBT with TRT (including bilateral sound generators as per TRT protocol). CBT may reduce the impact of tinnitus on quality of life as measured by the THI when compared with TRT (range 0 to 100) (MD -15.79, 95% CI -27.91 to -3.67; 1 study; 42 participants; low certainty). For serious adverse effects three participants deteriorated during the study: one in the CBT (n = 22) and two in the TRT group (n = 20) (RR 0.45, 95% CI 0.04 to 4.64; low certainty). We are uncertain whether CBT reduces depression and anxiety or improves health-related quality of life (low certainty). CBT may reduce negatively biased interpretations of tinnitus. No data were available for other adverse effects. CBT versus other active control Sixteen studies compared CBT with another active control (e.g. relaxation, information, Internet-based discussion forums). CBT may reduce the impact of tinnitus on quality of life when compared with other active treatments (SMD -0.30, 95% CI -0.55 to -0.05; 12 studies; 966 participants; low certainty). Re-expressed as a THI score this is equivalent to 5.84 points lower in the CBT group than the other active control group (MCID = 7 points). One study reported that three participants deteriorated: one in the CBT and two in the information only group (RR 1.70, 95% CI 0.16 to 18.36; low certainty). CBT may reduce depression and anxiety (both low certainty). We are uncertain whether CBT improves health-related quality of life compared with other control. CBT probably reduces negatively biased interpretations of tinnitus compared with other treatments. No data were available for other adverse effects. AUTHORS' CONCLUSIONS: CBT may be effective in reducing the negative impact that tinnitus can have on quality of life. There is, however, an absence of evidence at 6 or 12 months follow-up. There is also some evidence that adverse effects may be rare in adults with tinnitus receiving CBT, but this could be further investigated. CBT for tinnitus may have small additional benefit in reducing symptoms of depression although uncertainty remains due to concerns about the quality of the evidence. Overall, there is limited evidence for CBT for tinnitus improving anxiety, health-related quality of life or negatively biased interpretations of tinnitus.

Outcomes and Risk Factors of Revision and Replacement Artificial Urinary Sphincter Implantation in Radiated and Nonradiated Cases.

PURPOSE: Risk factors for complications after artificial urinary sphincter surgery include a history of pelvic radiation and prior artificial urinary sphincter complication. The survival of a second artificial urinary sphincter in the setting of prior device complication and radiation is not well described. We report the survival of redo artificial urinary sphincter surgery and identify risk factors for repeat complications. MATERIALS AND METHODS: A multi-institutional database was queried for redo artificial urinary sphincter surgeries. The primary outcome was median survival of a second and third artificial urinary sphincter in radiated and nonradiated cases. A Cox proportional hazards survival analysis was performed to identify additional patient and surgery risk factors. RESULTS: Median time to explantation of the initial artificial urinary sphincter in radiated (150) and nonradiated (174) cases was 26.4 and 35.6 months, respectively (p=0.043). For a second device median time to explantation was 30.1 and 38.7 months (p=0.034) and for a third device it was 28.5 and 30.6 months (p=0.020), respectively. The 5-year revision-free survival for patients undergoing a second artificial urinary sphincter surgery with no risk factors, history of radiation, history of urethroplasty, and history of radiation and urethroplasty were 83.1%, 72.6%, 63.9% and 46%, respectively. CONCLUSIONS: Patients without additional risk factors undergoing second and third artificial urinary sphincter surgeries experience revision-free rates similar to those of their initial artificial urinary sphincter devices. Patients who have been treated with pelvic radiation have earlier artificial urinary sphincter complications. When multiple risk factors exist, revision-free rates decrease significantly.
