Backpack satellite transmitters reduce survival but not nesting propensity or success of greater sage-grouse.

Telemetry technology is ubiquitous for studying the behavior and demography of wildlife, including the use of traditional very high frequency (VHF) radio telemetry and more recent methods that record animal locations using global positioning systems (GPS). Satellite-based GPS telemetry allows researchers to collect high spatial-temporal resolution data remotely but may also come with additional costs. For example, recent studies from the southern Great Basin suggested GPS transmitters attached via backpacks may reduce the survival of greater sage-grouse (Centrocercus urophasianus) relative to VHF transmitters attached via collars that have been in use for decades. While some evidence suggests GPS backpacks reduce survival, no studies have examined the effects of GPS backpacks on breeding behavior and success. Therefore, we compared survival, breeding behavior, and nest success of sage-grouse hens marked with both VHF collars and GPS backpack transmitter over a 7-year period in central Idaho, USA. GPS backpacks reduced spring-summer survival of sage-grouse hens relative to hens with VHF collars, where daily mortality probability was 68%-82% higher from March 1 to August 1. Yet satellite GPS backpacks did not consistently affect nest success or the likelihood or timing of nest initiation relative to VHF collars. Daily nest survival varied annually and with timing of nest initiation and nest age, but marginal effects of transmitter type were statistically insignificant and interactions between transmitter type and study year produced no meaningful patterns. Our results corroborate recent studies for the effect of satellite GPS backpacks on sage-grouse survival, but also suggest that these transmitters do not appear to affect components of fecundity. Our results therefore add important context to recent debate surrounding the effects of GPS backpacks on sage-grouse, and the relative strengths and weaknesses of different transmitter types for understanding behavior and population dynamics.

Intravenous Dexmedetomidine Use in Total Hip Arthroplasty May Lead to Elevated Rates of Hypotension.

Purpose Enhanced recovery protocols for total hip arthroplasty (THA), using opioid-sparing techniques have become widely used. Reports of novel additions to multimodal pain control regimens have been published, however, a paucity of literature exists on the use of intravenous dexmedetomidine. In this study, we analyzed our experience with intravenous dexmedetomidine and hypothesized that it would reduce postoperative opioid use. Secondary outcomes were also examined, including post-operative hypotension, hemoglobin, length of stay, and discharge disposition. Methods All patients who underwent primary THA at a single tertiary-level center between January 1, 2016, and September 1, 2019, underwent investigation. Diagnosis, surgical approach, anesthetic type, body mass index (BMI), and American Society of Anesthesiologists (ASA) score were recorded. Postoperative clinical measures were analyzed, adjusting for patient and surgical characteristics. Results Of the 599 patients included in the study, 218 patients received intravenous (IV) dexmedetomidine, at a mean dose of 44.9 mg during their operative event. Using a multivariate model, patients in the IV dexmedetomidine group were estimated to have received 24% elevated morphine milligram equivalent at postoperative day zero compared to those in the control group (p = 0.05). In addition, patients in the IV dexmedetomidine group who underwent spinal anesthesia had increased odds of hypotension 3.47 times that of the control [odds ratio (OR) 1.43-8.43, p=0.006]. Conclusions Surprisingly, we found no opioid-sparing effects with the use of IV dexmedetomidine. IV dexmedetomidine may be used cautiously as an anesthesia adjunct with spinal anesthesia in the setting of primary THA, as the experience at our institution illustrated increased odds of postoperative hypotension. Level of evidence This retrospective case-control study has a level of evidence III.

Comparing Perceived Radiograph Quality Between Radiologic Technologists and Orthopedic Surgeons.

PURPOSE: To determine if there is a discrepancy between how orthopedic surgeons perceive the quality of plain radiographs compared with that of radiologic technologists. METHODS: A prospective survey was developed including 42 deidentified plain radiographs. Included radiographs were of varying anatomical regions, patient positioning, and radiographic parameters. Participants were requested to score each radiograph on a scale from 1 (very poor) to 100 (very good) based on their overall subjective definition of radiographic quality. RESULTS: Multiple analyses of variance showed that out of the 42 radiographs evaluated, 13 images had significant differences in how they were scored by each group. Technologists provided lower image quality scores for 11 images compared with the orthopedic residents and attending surgeons. Two images were scored significantly higher by the attendings compared with the technologists or residents. Of the 42 images, 29 were scored similarly by the 3 groups. DISCUSSION: This study is novel because it explored perceived radiograph quality between attending orthopedic surgeons, orthopedic surgery residents, and radiologic technologists. Review of current literature revealed comparisons of radiography quality assessments between radiologic technologists and radiologists. Like the findings of the authors of the current report, the literature analysis demonstrated that radiologic technologists and radiologists appear to agree on what was considered a quality image, but technologists were more reluctant to accept images of lower quality than were radiologists. These authors believe the present study helps further establish that orthopedic surgeons typically order repeat imaging for reasons other than image quality. CONCLUSION: Orthopedic surgeons and radiologic technologists appear to agree in a subjective manner on a quantitative scale. Radiologic technologists tended to be more critical than were orthopedic surgeons in judging radiograph quality, contrary to the authors' original hypothesis.

Restoration of thoracic kyphosis in adolescent idiopathic scoliosis with patient-specific rods: did the preoperative plan match postoperative sagittal alignment?

PURPOSE: To determine if the planned sagittal profile for thoracic kyphosis (TK) restoration was achieved after adolescent idiopathic scoliosis (AIS) surgery using a novel hybrid construct with apical double bands and precontoured patient-specific rods (PSR) made according to the detailed surgical plan for the desired sagittal plane. METHODS: AIS patients with a Lenke type 1-4 primary right thoracic curve who underwent corrective surgery by a single surgeon and had minimum 24-month follow-up were analyzed retrospectively from a prospective database. All patients underwent simultaneous translation on two rods with apical double bands and PSR. Clinical outcomes in terms of sagittal 2D TK (T4-T12), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), PI-LL mismatch, rod angle, and rod deflection were compared between preoperative, planned, and 24-month data, while 3D apical rotation, 3D TK (T5-T12), sagittal thoracolumbar angle, degree of curvature at L1-L4 and L4-S1, proximal junctional angle, and distal junctional angle were compared at baseline and at 6 and 24 months postoperatively. SRS-22 questionnaire scores were obtained at baseline and 24 months postoperatively. RESULTS: Forty-eight patients were included. Study patients had a median coronal thoracic curve of 62.7° preoperatively and 22.4° at 24-month follow-up (p < 0.001). Median TK gain was 6.5° for the entire cohort (n = 48) and 19.1° in the Lenke type 1 and 2 hypokyphotic subgroup (n = 14). Both groups had no significant changes between planned and 24-month TK (p = 0.068 and p = 0.943, respectively), rod angle (p = 0.776 and p = 0.548, respectively), or rod deflection (p = 0.661 and p = 0.850, respectively). For the overall study cohort, median LL gain was 7.0° (p < 0.001), 3D apical derotation was 10.7° (p < 0.001), and change in 3D TK was 36° (p < 0.001). No instance of proximal junctional kyphosis was observed. SRS-22 scores for pain, self-image, and satisfaction differed significantly between the preoperative and 24-month follow-up time-points. CONCLUSIONS: With sagittal plane planning, desired TK, improved reciprocal changes in LL, and minimal changes in rod shape can be achieved in patients with AIS.

Dropout from face-to-face, multi-session psychological treatments for problem and disordered gambling: A systematic review and meta-analysis.

OBJECTIVE: The aims of this systematic review and meta-analysis were to examine the overall prevalence of dropout from psychological treatments for problem gambling and gambling disorder and to examine how study, client, and treatment variables influenced dropout rates. METHOD: A systematic search was conducted to identify studies of cognitive and/or behavioral therapies and motivational interventions for problem gambling and gambling disorder. Meta-analysis was used to calculate an overall weighted dropout rate. Random effect meta-regressions were used to examine covariates of dropout rates. Mixed-effect subgroup analyses were used to examine moderators of dropout rates. RESULTS: The systematic search identified 24 studies (31 dropout rates) comprising 2,791 participants. Using a random-effects model, the overall weighted dropout rate was 39.1%, 95% CI [33.0%, 45.6%]. Increases in the percentage of married participants were significantly associated with lower dropout rates. Dropout rates were significantly higher when dropout was defined as attending all sessions of a treatment protocol compared to when defined as attending a prespecified number of sessions different from the total in the protocol and when defined as study therapists judging participants to be dropouts. Insufficient reporting of some gambling-related variables and other psychological symptom variables prevented a thorough examination of covariates and moderators. CONCLUSIONS: A large proportion of individuals drop out of treatment for problem gambling and gambling disorder. Future research should examine the reasons for dropout across marital statuses and should adopt dropout definitions that consider session-by-session symptom change.

Septic gonococcal arthritis in a pediatric patient: Rare case report.

INTRODUCTION: Septic arthritis is an orthopedic emergency that requires rapid diagnosis and treatment due to the rapid destruction to cartilage. The responsible organism and etiology differs depending on patient age, especially in children. Gonococcal Arthritis in toddlers is a rare occurrence with few documented cases in the literature. An orthopedic surgeon is likely not to come across this either in training or through their careers. Consequently, its presentation and subsequent treatment algorithms leave several gray areas. PRESENTATION OF CASE: In this case report, we present a rare and not so straightforward presentation of a toddler with septic gonococcal arthritis along with a summary of treatment considerations described in the current literature and the course of treatment for this patient. Our patient is a toddler who originally presented to the emergency department with shoulder and knee pain for several days after an unwitnessed fall. He was subsequently discharged and presented again the next day with a knee effusion and elevated inflammatory markers. An MRI showed a large joint effusion without any underlying abscess or osteomyelitis to explain his elevated inflammatory markers. A knee aspiration was subsequently preformed which eventually grew out Neisseria Gonorrhea on hospital day 3 after the patient had been on antibiotics. He was taken back for an arthroscopic irrigation and debridement for definitive treatment. CLINICAL DISCUSSION/CONCLUSION: Disseminated gonococcal infection in toddlers is a rare occurrence without much information in the literature and should not be dismissed as a differential. We recommend a high index of suspicion with thorough work up. We also recommend surgical management of a septic joint due to DGI diagnosed via arthrocentesis (gross purulence, symptoms not improving on medical therapy, positive aspiration cultures, elevated synovial cell counts, and medically unstable patients) given the sequelae of medical management alone. The importance of interdisciplinary team collaboration that include pediatrician, infectious disease specialist, social worker, and government child safety associations is pivotal.

Frequent Gamblers' Reasons for and Against Completing a Problem Gambling Screener.

Problem gambling screeners are easily accessible and potentially reduce harm for those individuals who engage in risky levels of gambling behavior. However, a recent study found that when frequent gamblers were offered the chance to complete a screener and receive feedback, most chose not to do so. In this paper, secondary analysis was completed on frequent gamblers' open-ended responses to questions regarding reasons for and against completing a problem gambling screener. Participants (N = 262) were individuals who gambled at least once per week and were not currently being treated for gambling problems. A qualitative open-coding procedure independently completed by multiple researchers revealed that the most common reasons for completing the screener were individuals having a desire to check in on their behavior, because they were curious about the screener, because they were experiencing gambling-related harm, or that they were already considering making changes to their gambling. The most common reasons against completing the screener were that they were either avoidant of the experience because they thought it might cause psychological distress, or because they believed that they did not have a problem. This study provides insight into why many individuals who engage in risky levels of gambling behavior do not seek out helping resources. In addition to creating practically accessible helping resources, researchers should focus on techniques that can make help-seeking a less distressing and more acceptable experience.

Can motivational messages engage individuals at-risk for gambling disorder in an online assessment?

There is a need to better understand how to motivate individuals experiencing addiction-related concerns, such as gambling problems, to engage in help-seeking behaviors. This experiment tested whether online messages based on principles of motivational interviewing (MI) could be used to encourage individuals to complete a problem gambling screener. Participants (N = 805) who gambled at least weekly and were not receiving treatment for gambling problems were recruited via Amazon Mechanical Turk. Participants were randomly assigned to 1 of 3 message conditions that all offered participants the choice to complete either a problem gambling screener or an alternative questionnaire focused on gambling-related attitudes. The first condition was an MI-based interactive message, the second was similar in content but was presented in a noninteractive manner, and the third was a control message that did not include motivational elements. We found that the interactive motivational message yielded significantly higher rates of screener completion (39%) than the noninteractive message (28%) or control message (29%), χ² (2, N = 805) = 8.28, p = .016, Φ = .29. This remained significant after controlling for other study variables. Controlling for message condition, participants were more likely to complete the screener if they gambled more frequently, with more money, were more psychologically distressed and interested in receiving help for gambling problems, or had ever received treatment for gambling problems. These findings provide support for the use of interactive MI-based messages to encourage individuals at-risk for experiencing problems to use helping resources.

Does L5-S1 Anterior Lumbar Interbody Fusion Improve Sagittal Alignment or Fusion Rates in Long Segment Fusion for Adult Spinal Deformity?

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To assess whether the addition of L5-S1 anterior lumbar interbody fusion (ALIF) improves global sagittal alignment and fusion rates in patients undergoing multilevel spinal deformity surgery. METHODS: Two-year radiographic outcomes, including lumbar lordosis, pelvic incidence, pelvic tilt, and T1 pelvic angle; hardware complications; and nonunion/pseudarthrosis rates were compared between patients who underwent lumbosacral fusion at 4 or more vertebral levels with and without L5-S1 ALIF between November 2003 and September 2016. RESULTS: A total of 51 patients who underwent fusion involving a mean of 11.1 levels with minimum 2-year postoperative radiographic follow-up data were included. Patients who underwent L5-S1 ALIF did not have significant improvement in global sagittal alignment parameters and demonstrated a trend toward a higher rate of nonunion and hardware failure. CONCLUSIONS: L5-S1 ALIF did not confer significant benefit in terms of global sagittal alignment and fusion rates in patients undergoing multilevel lumbosacral fusion. Given these results and that L5-S1 ALIF is associated with increased surgical morbidity, surgeons should be judicious in including L5-S1 ALIF in large multilevel constructs.

Sweetening the pot: Exploring differences between frequent gamblers who do and do not gamble under the influence of cannabis.

The legalization of recreational cannabis for adults is becoming more common across the United States of America, as well as other counties around the world. Previous research has documented shared risk factors between cannabis use and gambling. Experimental studies have shown cognitive effects of cannabis that might influence gambling behavior. The current study explored demographics, gambling behaviors, and mental health differences based on the degree to which individuals use cannabis while they gamble. Individuals (N = 805) who gambled at least weekly completed an online survey. Thirty percent reported gambling under the influence of cannabis. Of these individuals, 41% reported using cannabis 25% of the time that they gambled, 31% reported being under the influence 50% of the time when gambling, 16% were under the influence 75% of the time when gambling, and 13% reported always or almost always gambling under the influence of cannabis. Those who reported gambling while under the influence of cannabis were more likely to be younger, non-white and non-heterosexual. They also reported higher levels of psychological distress, were more likely to have had a diagnosis of ADHD and a history of treatment for gambling, substance use, or other kinds of mental health concerns. Individuals who used cannabis while gambling also reported gambling more frequently than those who did not. This study provides one of the first explorations into who uses cannabis while gambling. Future experimental studies are required to investigate the direct effects of cannabis on gambling behaviors.

Office-Based Needle Arthroscopy: A Standardized Diagnostic Approach to the Shoulder.

In-office needle arthroscopy offers the potential advantage of reduced injury to intervention time, without the need for advanced imaging. It is particularly appropriate for those with contraindications to advanced imaging and also may reduce the risk of incorrect diagnoses in those situations in which imaging is associated with low sensitivity/specificity. The purpose of this article is to provide a standardized diagnostic approach to needle arthroscopy of the shoulder.

Is more better? A meta-analysis of dose and efficacy in face-to-face psychological treatments for problem and disordered gambling.

A growing literature supports the efficacy of cognitive-behavioral therapies, motivational interventions, and personalized feedback to treat problem and disordered gambling. However, there is currently debate as to how much treatment is necessary. Some studies indicate that attending a greater number of sessions is related to enhanced therapeutic outcomes, while other studies indicate that one session produces equivalent therapeutic outcomes to multiple sessions. To contribute to this debate, meta-analysis was used to examine the relation between dose and outcome in studies of cognitive-behavioral, motivational, and personalized feedback interventions (both individual and group treatment formats were included). Fourteen studies of randomized controlled trials representing 1,203 participants across 19 treatment-control comparisons were identified. The intended treatment dose (i.e., the number of sessions prescribed to participants) across the 14 studies ranged from 1 to 30 sessions. Of the 10 studies reporting the received treatment dose (i.e., the number of sessions that participants attended), the weighted mean dose was 6.8 sessions (SD = 2.7). Both intended treatment dose and received treatment dose were positively related to outcome at posttreatment-as the number of sessions increased, so too did the magnitude of the between group effect size. There were an insufficient number of studies reporting outcome at long-term follow up to evaluate the relation between intended dose, received dose, and outcome. Discussion centers on several areas for future research on psychological treatments for problem and disordered gambling. Specific recommendations are made for researchers and practicing clinicians.

Can a motivational letter increase attendance to psychological treatment for gambling disorder?

High rates of treatment refusal and dropout have complicated the delivery of psychological treatment for gambling disorder, which continues accumulating evidence for efficacy. Incorporating motivational interviewing and addressing outcome expectations into psychological treatments has been shown to increase overall attendance. However, no studies have investigated whether motivational interviewing and outcome expectations can increase attendance at the initial and subsequent sessions of psychological treatment for gambling disorder. Participants were 69 prospective clients who contacted an outpatient training clinic requesting treatment services for gambling-related problems. They were randomly assigned to receive a mailed letter that incorporated principles of motivational interviewing and addressed outcome expectancies plus a telephone reminder call or to receive a telephone reminder call only. Clients who received the letter plus reminder call were more likely to attend the initial session than were clients who received the reminder call only. Clients receiving the letter were also more likely to reschedule their initial session and less likely to not show up than were clients receiving the reminder call only. There was no significant difference in attendance at subsequent sessions. These results suggest that mailing a similar letter to prospective clients of psychological treatment for gambling disorder is worthwhile, given the associated ease and low cost. Future investigations should further investigate the value of strengthening the motivation of prospective clients and clinics before initial treatment sessions, and they should investigate the distinction between clients who reschedule versus not show up.

Arthroscopic On-Lay Biceps Tenodesis: The Loop-Lock Technique.

The biceps tendon is a common pain generator in the shoulder. Long head of the biceps tendon pathology occurs in a variety of different ways. There are several different treatment options available to address the long head of the biceps. With advances in arthroscopy, all-arthroscopic tenodesis is becoming a more popular choice to address biceps tendon pathology. We describe an all-arthroscopic technique, termed "the loop-lock," for performing a biceps tenodesis.

A Meta-analysis of Brief Personalized Feedback Interventions for Problematic Gambling.

Personal Feedback Interventions (PFIs) have been widely used to reduce the amount of time and money individuals spend on gambling. A central component of these interventions is personalized information about an individual's gambling behavior, often in comparison to others' gambling. The purpose of the present review and meta-analysis was to evaluate these interventions in terms of content, mode of delivery, target sample, and efficacy. Sixteen interventions from 11 studies were reviewed. We found a small, statistically significant effect in favor of PFIs versus control (d = 0.20, 95% CI 0.12, 0.27). Six moderators of intervention efficacy were explored. These interventions appeared to be most efficacious when used in populations of greater gambling severity, when individuals were provided with gambling-related educational information, and when used in conjunction with motivational interviewing. Factors associated with reduced efficacy include in-person delivery of feedback without motivational-interviewing and informing participants of their score on a psychological measure of gambling severity. Efficacy did not vary as a function of college or community samples. PFIs are a low cost, easily disseminated intervention that can be used as a harm-reduction strategy. However, more substantial effects may be attained if used as part of a larger course of therapy.

Public Stigma Across Addictive Behaviors: Casino Gambling, eSports Gambling, and Internet Gaming.

The negative psychological effects of public stigma on disordered gamblers have been well documented. Public stigma deters treatment-seeking and other help-seeking behaviors, and negatively impacts individuals' view of themselves. Different types of disordered gambling activities may attract different degrees of stigma. One increasingly popular form of gambling involves placing bets on the outcomes of competitive video games, also called eSports gambling. This activity shares characteristics with Internet gaming and gambling. The purpose of this study was to compare the degree of public stigma held towards traditional casino gamblers, eSports gamblers, and Internet gamers, as compared to an individual experiencing comparable levels of impairment and distress due to a financial crisis. Using an experimental between-groups vignette study design, we found that all three types of behavioral addictions were more heavily stigmatized than the control condition. The three behavioral addictions were seen as being highly controllable, engendered a significant amount of anger and blame, and resulted in higher levels of desired social distance. Traditional casino gamblers were seen as significantly more dangerous to be around and created a higher level of desired social distance than the Internet gamer. Differences between the Internet gamer and eSports better were less pronounced. These findings underscore the importance of reducing public stigma for gambling and other behavioral addictions, and provide information that can be used when developing interventions to impact stigma.

A text comprehension approach to questionnaire readability: An example using gambling disorder measures.

Although readability has been traditionally operationalized and even become synonymous with the concept of word and sentence length, modern text analysis theory and technology have shifted toward multidimensional comprehension-based analytic techniques. In an effort to make use of these advancements and demonstrate their general utility, 6 commonly used measures of gambling disorder were submitted to readability analyses using 2 of these advanced approaches, Coh-Metrix and Question Understanding Aid (QUAID), and one traditional approach, the Flesch-Kincaid Grade Level. As hypothesized, significant variation was found across measures, with some questionnaires emerging as more appropriate than others for use in samples that may include individuals with low literacy. Recommendations are made for the use of these modern approaches to readability to inform decisions on measure selection and development. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

When Does Premature Treatment Termination Occur? Examining Session-by-Session Dropout Among Clients with Gambling Disorder.

Premature termination challenges the successful outcomes of psychological treatments for gambling disorder. To date, research has primarily identified clients who are at particular risk for dropping out of treatment. A smaller but growing body of literature has investigated when dropout occurs. Typically, those studies have not considered improvement in psychological distress within their operationalizations of dropout and therefore may have misrepresented when dropout occurs. The current study examined when dropout occurs using an operationalization based on the criteria of attaining reliable change in a naturalistic sample of clients with gambling disorder, and the classification rates yielded from that operationalization were compared to the rates from a more common operationalization. Participants (n = 334) were clients meeting diagnostic criteria for gambling disorder at an outpatient private practice who completed a measure of psychological distress at baseline and prior to each subsequent treatment session. A survival analysis was conducted to determine temporal patterns of treatment dropout (i.e., clients who discontinued treatment before realizing reliable changes in psychological distress) and completion (i.e., clients who discontinued treatment after realizing reliable changes in distress) at each treatment session. Forty-nine percent of clients were classified as dropouts, and the majority of those clients did so in the first few sessions. The more common operationalization of dropout classified clients as dropouts when they had improved in their distress and clients as completers when they had not improved in their distress. Discussion centers on the implications of dropout occurring at various stages of treatment and future directions.

Pseudotumor in ceramic-on-metal total hip arthroplasty.

The increasing demand for total hip arthroplasty (THA) in relatively young, high-demand patients has led to the use of hard-on-hard bearing surfaces. Adverse local tissue reaction/pseudotumor and elevated serum metal ion levels are commonly reported complications encountered in metal-on-metal THA, while audible articulation and rim fracture are reported in ceramic-on-ceramic THA. For this reason, ceramic-on-metal THA was implemented as an ideal hard-on-hard bearing combination. In this report, we describe a case of bilateral simultaneous ceramic-on-metal THA in a 69-year-old woman who presented 7 years postoperatively with unilateral hip pain associated with underlying pseudotumor and elevated serum cobalt and chromium ion levels. Pre-revision workup, intraoperative findings, and postoperative evaluation are included and suggest acetabular malposition as a potential source for complication.
