Background: The use of corticosteroids has become a part of the standard of care in various pathologies but their use in peripheral nerve injury treatment is limited. Given corticosteroids' anti-inflammatory properties and their regulatory role in neuronal protein production and myelination, corticosteroids could serve as an adjunct therapy for peripheral nerve injuries. This review aims to systematically investigate the current use of corticosteroid treatment in peripheral nerve pathologies., Methods: The systematic search was performed on PubMed, MEDLINE, EMBASE, Scopus, Cochrane, and Web of Science using keywords such as "corticosteroid treatment," "peripheral nerve damage," "peripheral neuropathy," and "complications." The PRISMA guidelines were used to conduct the systematic review and all articles were reviewed by the corresponding author. After the initial search, individual study titles and abstracts were further screened and categorized using an inclusion and exclusion criteria followed by a final full-text review., Results: Out of the total 27,922 identified records, 203 studies were included based on the selection criteria. These studies focused on the use and efficacy of steroids across a spectrum of compression and non-compression peripheral neuropathies such as cubital tunnel syndrome and chronic inflammatory demyelinating polyradiculoneuropathy. Various studies noted the promising role of steroids in offering pain relief, nerve block, and nerve regeneration effects. Additionally, safety considerations and potential complications regarding steroid use in peripheral nerve injuries were analyzed., Conclusion: While there is currently limited clinical utilization of corticosteroids in peripheral nerve pathologies, the anti-inflammatory and regenerative effects that steroids provide may be a beneficial tool in managing various peripheral neuropathies and their associated pain. Additional clinical trials and investigation into the mechanism of action could improve the reputation of steroid use as peripheral nerve injury treatment., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Couch, Hayward, Baum, Sakthiyendran, Harder, Hernandez and MacKay.)

Background: The opioid crisis has become a present concern in the medical field. In an effort to address these complications, antineuropathic pain medications have been considered as alternatives to prescribed opioids., Objective: This review focuses on the analgesic effects of neuromodulators, such as gabapentin, duloxetine, and pregabalin, that provide room for less dependence on narcotic analgesics following orthopedic surgery., Methods: During the database searches, 1,033 records were identified as a preliminary result. After duplicates were removed, an initial screen of each article was completed which identified records to be removed due to absence of a full-text article. Articles were excluded if they were not either prospective or retrospective, showcased an irrelevant medication (such as tricyclic antidepressants) which are not pertinent to this review, or deemed to be unrelated to the topic., Results: Ultimately, 19 articles were selected. Three different drugs, gabapentin, pregabalin, and duloxetine, were analyzed to compile data on the effectiveness of preventing opioid overuse and addiction following hand surgery. This review identifies potential evidence that peri-operative gabapentin, pregabalin, and duloxetine administration decreases post-operative pain and lowers opioid dependency., Conclusion: Gabapentin, pregabalin, and duloxetine have potential to further decrease post-operative pain and lower opioid dependency. This review creates an opening for further research in hand surgery to assess an updated protocol for pain management to reduce opioid dependency., Competing Interests: The authors declare no conflict of interest.

Chronic distal radioulnar joint (DRUJ) instability is a complex clinical condition that is difficult to treat. Currently, there is no gold standard treatment. We present a novel technique using Arthrex Mini Tightrope for DRUJ stabilization. In this case series, a 1.6 mm K-wire was passed transversely through the distal ulna and radius. The Mini Tightrope was inserted into the end of the K-wire and pulled through the bone tunnels. Appropriate tension was achieved to stabilize the joint according to individual laxity comparable to the contralateral side. Five patients (3 males and 2 females) comprised this pilot series, with a mean age of 27.1 years. All sustained a traumatic injury at an average of 12.4 months before surgery (range: 5 to 32 mo). In addition, 3 patients had central triangular fibrocartilage complex tears treated with arthroscopy at the time of Mini Tightrope placement. While one patient was lost to follow-up after 7 weeks postoperative due to incarceration, 4 patients demonstrated coronal and sagittal stability in the context of DRUJ motion and a satisfactory range of motion. The mean time for the return to work for the two patients who were laborers or normal activity postoperatively was 5.2 weeks (range: 1 to 16.4 wk). Unrestricted activity was generally allowed 8 weeks postoperatively but varied by patient. The same 4 patients underwent hardware removal at an average of 31 weeks (range: 15 to 44 wk). Although this is only a pilot series, this suggests that temporary Mini Tightrope stabilization of the DRUJ may be a viable solution while upholding the benefits of minimally invasive surgery., Competing Interests: Conflicts of Interest and Source of Funding: The authors report no conflicts of interest and no source of funding., (Copyright © 2023 The Author(s).

Metacarpal fractures are common and may require operative treatment; however, there is no gold standard fixation technique. K-wires are used for simplicity and flexibility but require immobilization and can lead to complications. Dorsal plating provides greater stability than K-wires but is subject to its own limitations. Intramedullary threadless nails have reduced time to union and improved range of motion (ROM) but may not provide the stability of plating. Intramedullary screws allow rapid return to activity and increased stability; however, compression forces may shorten metacarpals, producing non-anatomic reduction. The ExsoMed INnate TM threaded intramedullary nail (ExsoMed, Aliso Viejo, CA, USA) was developed with tall threads, a diameter fitting the metacarpal canal cortical purchase, stability, and no compression to prevent fracture displacement and shortening. We designed a prospective study to evaluate INnate TM nail fixation in metacarpal fractures. Visual analog scale (VAS) pain score, total active motion (TAM), radiographic union, and return to normal activity were recorded at each postoperative visit. Descriptive statistics were performed for endpoints. Fifty-eight patients were included with a median age of 38.7 years. The INnate TM nail was used in 80 fractured metacarpals. The 4th and 5th metacarpals were most frequently involved. The most common mechanisms of injury were blunt trauma and motor vehicle collisions. Approximately 31% of patients had multiple, concurrent fractures (16 patients required two nails; two required three nails). The mean follow-up was 9.9 weeks. The mean time to radiographic union was 9.1 weeks. The final visual analog scale (VAS) pain score was 1.1. The mean time to return to work and/or normal activities was 9.7 weeks, and the mean percentage of normal activity resumed was 89.1%., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2023, Giron et al.)

A major cause of chronic liver disease, cirrhosis, and hepatocellular carcinoma, non-alcoholic fatty liver disease (NAFLD) results from excessive liver fat accumulation. Vitamin D (VitD) plays multiple important roles in diverse physiologic processes. Here, we describe the role of VitD in the complex pathogenesis of NAFLD and explore the possible therapeutic role of VitD supplementation in NAFLD therapy. To compare the effect of VitD to other interventions such as low-calorie diet, we induced NAFLD in young adult zebrafish ( Danio rerio , AB strain) and monitored the effects of VitD supplementation on the disease course. The zebrafish administered with high-dose VitD (1.25 μg) had significantly reduced liver fat compared to those that received low-dose VitD (0.049 μg) or caloric restriction. Gene expression analysis revealed that VitD downregulated several pathways that may play a role in NAFLD etiology, which affected fatty acid metabolism, vitamins and their cofactors, ethanol oxidation, and glycolysis. The pathway analysis revealed that the cholesterol biosynthesis pathway and the isoprenoid biosynthetic process pathway were significantly upregulated whereas the small molecule catabolic process pathway significantly downregulated following the exposure of NAFLD zebrafish model to high VitD dose. Therefore, our findings suggest the association of novel biochemical pathways with NAFLD and highlight the potential of VitD supplementation to reverse the severity of NAFLD, especially in younger people.

Objectives: To investigate obese versus non-obese subjects´ knee joint function, stiffness, pain, expectations, and outcome satisfaction before and two months after total knee arthroplasty (TKA)., Methods: This study is a secondary analysis of data retrieved via a prospective single-centre cohort study investigating knee joint function and health care services utilization in patients undergoing TKA (FInGK Study). For the primary study, elective TKA patients were consecutively recruited between December 2019 and May 2021. Preoperative expectations, Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC), surgery outcome satisfaction, and sociodemographic variables were assessed via self-reported questionnaires. In the current study, obese (Body Mass Index (BMI) ≥ 30 kg/m²) versus non-obese (BMI < 30 kg/m²) subjects' data were exploratively compared before and two months after TKA. Multivariable logistic regression assessed factors associated with TKA satisfaction two months postoperatively. Linear regression evaluated factors associated with higher WOMAC change two months postoperatively., Results: A total of 241 subjects participated (response: 85.2%). Eighty-seven were non-obese (mean age: 70.7 years, 63.2% female) and 154 were obese (mean age: 67.1 years, 57.8% female). Obese subjects reported inferior pre- and postoperative pain and knee joint function compared to non-obese subjects. Yet, WOMAC scores of obese and non-obese subjects significantly improved from preoperative means of 52.6 and 46.8 to 32.3 and 24.4 after surgery, respectively. The only significant TKA satisfaction predictor was subjects' smoking status. Non-obesity and worse preoperative WOMAC scores were predictive of higher WOMAC change scores after two months., Conclusion: Both obese and non-obese subjects reported significant symptom improvements. However, as obese subjects' short-term outcomes were still inferior, more research on TKA rehabilitation measures adapted to the needs of this growing patient group is warranted to maximize their benefits from TKA., (© 2022.

Purpose of Project: The purpose of the inpatient psychiatric unit denials reduction project was to establish a taskforce to analyze denials data for root cause and identify an effective solution to prevent denials through improved provider documentation., Primary Practice Setting: The development and implementation of the project occurred at Stanford Health Care, a nonprofit Level 1 trauma hospital, with a 29-bed inpatient psychiatric unit containing both open and secured levels of care. The project was led by the Utilization/Denials Management team, which is subteam within the Case Management Department. Team members are Nurse Case Managers specializing in the management of denials and appeals, data analysis and trending of denials, denial avoidance, and reduction of financial risk., Methodology: Denials data analysis revealed the Psychiatry Service Line was responsible for over 70% of payer denials within the Length of Stay Write-offs category. In early 2019, the Utilization/Denials Management team initiated a quality improvement project using A3 Lean Approach methodology and evidence-based practice to guide the implementation. The partnership and collaboration included Case Management, Revenue Cycle, Clinical Documentation Improvement, Technology and Digital Solutions, and Psychiatry Service Line leadership that had an interest in reducing payer denials., Results: Outcomes measured for the project were based on denials data for (fiscal year) FY19, the preintervention period, compared to FY20 and FY21, the postintervention period. From FY19 to FY20, revenue loss decreased by 42%. The downward trend continued from FY20 to FY21 with a recorded decrease by 69%., Implications for Case Management Practice: The most important implication of the project was improved physician documentation and medical necessity supporting the severity and intensity of inpatient psychiatric level of care, and medical justification for the inpatient stay not only to prevent medical necessity denials but to accurately reflect the care that was provided. High-quality documentation correlates to the high quality of care being provided. This project is far reaching not only for psychiatric units but also reproducible for other acute hospital service lines. Case Management is a multidisciplinary role, and this work is most meaningful for a Nurse Case Manager engaged in care coordination, including utilization and denials management., Competing Interests: The authors report no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Spouses offer a primary source of support and may provide critical assistance for behavior change. A diet-exercise intervention previously found efficacious in improving cancer survivors' lifestyle behaviors was adapted to utilize a couples-based approach. The aims were to test the feasibility of this couples-based (CB) intervention and compare its efficacy to the same program delivered to the survivor-only (SO). Twenty-two survivor-spouse couples completed baseline assessments and were randomized to the CB or SO interventions. The study surpassed feasibility benchmarks; 91% of survivors and 86% of spouses completed a 6-month follow-up. Survivors and spouses attended 94% and 91% of sessions, respectively. The SO survivors showed significant improvements on the 30-s chair stand and arm curl tests, weight, and fruit and vegetable (F and V) consumption. The CB survivors showed significant improvements on the 6-min walk and 2-min step tests, body weight, and fat and F and V consumption. Improvement in the 30-s chair stand and arm curl tests was significantly better for SO survivors. The SO spouses showed no significant changes in outcome measures, but the CB spouses showed significant improvements in moderate-to-strenuous physical activity, weight, and fat and F and V consumption. Weight loss was significantly greater in CB spouses compared to SO spouses. Findings demonstrate feasibility, warranting further investigation of CB approaches to promote lifestyle change among cancer survivors and spouses.

Fusion genes or chimeras typically comprise sequences from two different genes. The chimeric RNAs of such joined sequences often serve as cancer drivers. Identifying such driver fusions in a given cancer or complex disease is important for diagnosis and treatment. The advent of next-generation sequencing technologies, such as DNA-Seq or RNA-Seq, together with the development of suitable computational tools, has made the global identification of chimeras in tumors possible. However, the testing of over 20 computational methods showed these to be limited in terms of chimera prediction sensitivity, specificity, and accurate quantification of junction reads. These shortcomings motivated us to develop the first 'reference-based' approach termed ChiTaH ( Chi meric T r a nscripts from H igh-throughput sequencing data). ChiTaH uses 43,466 non-redundant known human chimeras as a reference database to map sequencing reads and to accurately identify chimeric reads. We benchmarked ChiTaH and four other methods to identify human chimeras, leveraging both simulated and real sequencing datasets. ChiTaH was found to be the most accurate and fastest method for identifying known human chimeras from simulated and sequencing datasets. Moreover, especially ChiTaH uncovered heterogeneity of the BCR-ABL1 chimera in both bulk and single-cells of the K-562 cell line, which was confirmed experimentally., (© The Author(s) 2021.

Study Design: Retrospective radiographic review., Objectives: The Global Alignment and Proportion (GAP) score allows sagittal plane analysis for deformity patients and may be predictive of mechanical complications. This study aims to assess the effectiveness of predicting mechanical failure based on partial intraoperative GAP (iGAP) scores., Methods: A retrospective radiographic review was performed on 48 deformity patients between July 2015 to January 2017 with a 2-year follow-up. Using the same methodology as the original GAP study, the partial iGAP score was calculated with the sum of the scores for age, relative lumbar lordosis (RLL), and lordosis distribution index (LDI). Therefore, the iGAP score (0-7) was grouped into proportional (0-2), mildly disproportionate (3-5), and severely disproportionate (6-7). Logistic regression was performed to assess the ability of the partial iGAP score to predict postoperative mechanical failure., Results: The mean iGAP for patients with a mechanical failure was 3.54, whereas the iGAP for those without a mechanical failure was 3.46 ( P = .90). The overall mechanical failure rate was 27.1%. The mechanical failures included 8 proximal junctional kyphosis, 7 rod fractures, and 1 rod slippage from the distal end of the construct. Logistic regression analysis revealed that the partial iGAP score was not able to predict postoperative mechanical failure (χ 2 = 1.4; P = .49)., Conclusion: The iGAP scores for RLL or LDI did not show any significant correlation to postoperative mechanical failure. Ultimately, the proposed partial iGAP score did not predict postoperative mechanical failure and thus, cannot be used as an intraoperative alignment assessment to avoid postoperative mechanical complications.

Objective: To replace educational opportunities lost during the coronavirus disease 2019 (COVID-19) pandemic, the Department of Neurosurgery at Lenox Hill Hospital produced an open-access webinar series ("BRAINterns") that covered a broad range of health care topics with a focus on neurosurgery., Methods: This 8-week webinar series ran from July 1 to August 28, 2020. An optional exit survey was distributed to participants. Data were analyzed to characterize and better understand trends among a global cohort of participants., Results: A total of 16,484 people registered for BRAINterns, and 6675 took the survey (40.5% response rate). Responders represented 87 countries, of which the majority were from the United States and Canada (90.48%, n = 6039). Responders were primarily female (82.9%, n = 5521). Racial and ethnic representation was majority Asian (42%, n = 2798), followed by White (22.7%, n = 1514), Hispanic/Latino (16.2%, n = 1080), and Black and African American (7.7%, n = 516). Participants reported hearing about BRAINterns through various social media platforms (72.18%, n = 4818)-the most popular was TikTok (33.4%, n = 2232). Overall, 93.4% of participants reported that the course was a good use of their time during the pandemic, and 86.7% reported that the course helped replace lost opportunities., Conclusions: These data demonstrate that webinar-based education is an effective method of expanding access to careers in medicine and in particular, neurosurgery, to traditionally underrepresented populations. Social media can be a powerful tool to combat barriers to early exposure and vastly improve diversity within the field., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Background: The coronavirus disease 2019 (COVID-19) pandemic has infected more than 13 million people on a global scale and claimed more than half million deaths across 213 countries and territories. While the focus is currently on recovery from the pandemic, the disease has significantly changed the way we practice medicine and neurosurgery in New York City and the United States. Apart from the emergency cases, several health systems across the country have similarly started to perform elective surgeries. Although COVID-19 screening and testing guidelines have been proposed and adopted by many hospitals, these may not adequately protect the operating room personnel who are in proximity to the patient for prolonged periods. There are concerning reports of especially high transmission rates of COVID-19 in transmucosal head and neck procedures conducted by otolaryngologists and neurosurgeons, despite attempts at wearing what constitutes appropriate personal protective equipment., Methods: Here, we describe a simple technique of additional draping that can be used for all cranial, endonasal, spinal, and neurointerventional cases to limit the transmission of coronavirus., Results: The proposed technique offers a simple, commonly available, cost-effective alternative that avoids the use of additional retractor systems. Moreover, this technique can be used in all neurosurgical procedures., Conclusions: With the rising concerns regarding airborne spread of the virus, we expect that these precautions will prove highly useful as we enter the recovery phase of this pandemic and hospitals attempt to prevent a return to widespread infection. In addition, its availability and cost effectiveness make this technique especially attractive to practical use in centers with limited resources., (Copyright © 2020 Elsevier Inc.

Study Design: Retrospective cohort. We present a simple classification system that is able to identify patients with increased odds of losing intraoperative neuromonitoring data during thoracic deformity correction. Type 3 spinal cords, with the cord deformed against the concave pedicle in the axial plane, have ×28 greater odds of losing monitoring data during surgery., Objectives: Assess preoperative morphology of the spinal cord across the thoracic concavity to predict intraoperative loss of neuromonitoring data., Methods: 128 consecutive patients undergoing surgical correction of a thoracic deformity with pedicle screw/rod constructs were included. Spinal cords were classified into 3 types based on the appearance of the cord on the axial-T2 MRI at the apex of the curve. Type 1 is defined as a circular/symmetric cord with visible CSF between the cord and the apical concave pedicle/vertebral body. Type 2 is a circular/oval/symmetric cord with no visible CSF between the concave pedicle and the cord. Type 3 is a spinal cord that is flattened/deformed by the apical concave pedicle or vertebral body, with no intervening CSF (Fig. 1)., Results: 128 patients were reviewed: 81 (63%) Type 1; 32 (25%) Type 2; and 12 (11.7%) Type 3 spinal cords. Lower extremity trans-cranial motor-evoked Potentials (MEPs) and/or somatosensory evoked potentials (SSEPs) were lost intraoperatively in 21 (16%) cases, with full recovery of data in 20 of those cases. On regression analysis, a Type 1 cord was protective against intraoperative data loss (OR = 0.17, p = 0.0003). Type 2 cords had no association with data loss (OR = 0.66, p = 0.49). Type 3 cords had significantly higher odds of intraoperative data loss (OR = 28.3, p < 0.0001)., Conclusions: We present a new spinal cord risk classification scheme to identify patients with increased odds of losing spinal cord monitoring data with thoracic deformity correction. The odds of losing intraoperative MEPs/SSEPs are greater in type 3 spinal cords., Level of Evidence: III.

Background: The Coronavirus disease 2019 (COVID-19) outbreak has left a lasting mark on medicine globally., Methods: Here we outline the steps that the Lenox Hill Hospital/Northwell Health Neurosurgery Department-located within the epicenter of the pandemic in New York City-is currently taking to recover our neurosurgical efforts in the age of COVID-19., Results: We outline measurable milestones to identify the transition to the recovery period and hope these recommendations may serve as a framework for an effective path forward., Conclusions: We believe that recovery following the COVID-19 pandemic offers unique opportunities to disrupt and rebuild the historical patient and office experience as we evolve with modern medicine in a post-COVID-19 world., (Copyright © 2020 Elsevier Inc.

C1 stenosis is often an easily missed cause for cervical myelopathy. The vast majority of cervical myelopathy occurs in the subaxial cervical spine. The cervical canal is generally largest at C1/2, explaining the relatively rare incidence of neurological deficits in patients with odontoid fractures. However, some subjects have anatomical anomalies of the atlas, which may cause stenosis and result in clinical symptoms similar to subaxial cord compression. Isolated pure atlas hypoplasia leading to stenosis is quite rare and may be associated with other anomalies, such as atlas clefts or transverse ligament calcification. It may also be more commonly associated with syndromic conditions such as Down or Turner syndrome. Although the diagnosis can be easily made with a cervical magnetic resonance imaging, the C3/2 spinolaminar test using a lateral cervical plain radiograph is a useful and sensitive tool for screening. Surgical treatment with a C1 laminectomy is generally necessary and any atlantoaxial or occipito-atlanto instability must be treated with spinal stabilization and fusion.

The diagnosis of cervical spondylotic myelopathy (CSM) is made based on clinical signs and symptoms, and then confirmed with magnetic resonance imaging (MRI) or CT myelogram. Due to the highly mobile nature of the cervical spine, and the fact that most MRIs and CTs are obtained only in one single position, dynamic cord compression can be an elusive diagnosis that is often missed and not well-understood. In this context, dynamic MRI (dMRI) has been utilized to improve the diagnostic accuracy of cervical stenosis in cases where static MRI does not provide enough information to establish a diagnosis or to provide additional information. We performed a literature review on dynamic cord compression in the context of CSM, with particular emphasis on the role of dynamic MRI (dMRI). Cadaveric studies report that the spinal cord lengthens in flexion and the spinal canal dimension increases, whereas the spinal cord relaxes and shortens in extension and the spinal canal decreases. These changes may lead to biomechanical stress in the spinal cord with movement, especially in patients with critical cervical stenosis. The majority of the studies using dMRI in CSM reported that this imaging modality is more sensitive at detecting cervical cord compression compared to routine MRIs done in a neutral position, especially with the neck in extension. Occult anterior compression has also been reported by some authors in flexion, but occurs less frequently. DMRI was also useful to diagnose dynamic cervical cord compression after laminectomies in patients with clinical deterioration without evident cord compression on neutral static MRI. Finally, dMRI are more sensitive in detecting stenosis in patients with CSM than in those with OPLL, likely because OPLL patients often have a more limited ROM than CSM patients. Thus, dMRI is a promising new tool that can help spine surgeons in diagnosing and treating CSM. However, further studies are needed to establish the utilization criteria and the clinical value of dMRI.

Background: Endometrial cancer survivors are at an increased risk of poor quality of life outcomes. Physical activity is positively associated with general quality of life in this population, however, little is known about how changes in physical activity may be associated with changes in specific aspects of quality of life. The aim of this secondary data analysis was to explore the relationships between change in physical activity and change in physical, mental, social, and other aspects of quality of life in endometrial cancer survivors receiving a physical activity intervention., Methods: Endometrial cancer survivors (N = 100) participated in a telephone-based physical activity intervention for six months. At baseline and post-intervention we measured physical activity via accelerometry and ecological momentary assessment, and quality of life via the Short Form Health Survey (SF-36), the Quality of Life of Adult Cancer Survivors instrument, the Brief Symptom Inventory, the Pittsburgh Sleep Quality Index, and the Perceived Stress Scale. We conducted structural equation modeling path analyses to investigate how physical activity post-intervention was associated with the quality of life measures' subscales post-intervention, adjusting for baseline levels and potentially confounding covariates., Results: Increasing physical activity was positively associated with improvements in general health (p = .044), role limitation due to physical health (p = .005), pain (p = .041), and somatic distress (p = .023). There was no evidence to indicate that change in physical activity was associated with change in other aspects of quality of life., Conclusions: Endometrial cancer survivors are at higher risk for suffering from challenges to physical quality of life, and findings from this study suggest that increasing physical activity may alleviate some of these problems. Further research is needed to determine whether other aspects of quality of life are linked to change in physical activity., Trial Registration: Trial registration number: NCT00501761 Name of registry: clinicaltrials.gov Date of registration: July 16, 2007. Date of enrollment: June 16, 2005.

The recruitment and retention of Aboriginal and Torres Strait Islander nurses and midwives is key to the delivery of culturally appropriate health care and improving the health outcomes of Aboriginal and Torres Strait Islander people. A working group to address inclusion and engagement of Aboriginal and Torres Strait Islander students at a West Australian University has impacted on the curricula, faculty staff and Aboriginal and Torres Strait Islander students within the School of Nursing and Midwifery. The University's Reconciliation Action Plan was the foundation and catalysed the group to promote cultural safety education for staff and provide inclusive activities for Aboriginal and Torres Strait Islander students. A conceptual framework was developed to demonstrate the action taken within the School of Nursing and Midwifery to address the inequity for Aboriginal and Torres Strait Islander students that could be seen to exist. Through collaboration with staff and students, both Aboriginal and Torres Strait Islander people and non-Aboriginal people, a shared understanding and goal setting has developed to enable positive action to provide ongoing support for these students at all parts of their journey in higher education. This paper will highlight the process involved to promote the recruitment, retention and academic success of these students., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Objective: Breast cancer survivors often take hormonal treatments to prevent the recurrence of breast cancer, particularly aromatase inhibitors that can worsen the symptoms of genitourinary syndrome of menopause (GSM) such as dyspareunia, dysuria, and urinary incontinence, all of which may adversely affect survivors' quality of life. Few breast cancer survivors experiencing GSM receive adequate assessment or treatment., Methods: In this descriptive study, we reviewed medical records for documented GSM and any treatments administered or referrals for treatment in 800 female patients who visited the Breast Cancer Survivorship Clinic at a comprehensive cancer center between July 1, 2010 and June 30, 2011, either at least 5 years after completion of treatment for invasive breast cancer or at least 6 months after completion of treatment for ductal carcinoma in situ., Results: Of the 279 patients with documented symptoms of vaginal atrophy, only 111 (39.8%) had documentation of having received any form of treatment or referral. Of the 71 patients with documented symptoms of urinary tract atrophy, only 33.8% had documentation of having received treatment or referral for treatment., Conclusion: Breast cancer survivors often experience GSM due to lack of estrogen. The worrisome lack of documentation of assessment or treatment for GSM in a large breast cancer survivorship practice reveals missed opportunities to improve quality of life. Dissemination of recent progress in the development of GSM assessment tools, patient handouts, and new treatments to providers who care for breast cancer survivors is needed to improve this process.

For cancer survivors, who also often present with co-existing health conditions, exercise testing is often performed using submaximal protocols incorporating linear heart rate response for estimating the cardiorespiratory capacity and assessing exercise tolerance. However, use of beta-blocker medications, during sub-maximal protocols based on linear HR response can be problematic. Rating of perceived exertion (RPE), which takes into account an individual's overall perception of effort, can be used as a complementary tool that does not rely solely on the heart rate response to increased workload. We compared heart rate response (VO 2 HR) and self-rating of perceived exertion (VO 2 RPE) in a graded submaximal exercise test (GXT) in 93 endometrial cancer survivors. The results of the GXT were stratified according to whether participants were taking beta-blocker (BB) medications or not (non-BB). Among non-BB participants, there was no difference between the mean VO 2 HR and the mean VO 2 RPE estimates of cardiorespiratory capacity (mlO 2/ /kg/min) (20.4 and 19.3, respectively; p = 0.166). Among BB participants, the mean VO 2 HR approached significant difference than the mean VO 2 RPE (21.7 mlO 2/ /kg/min and 17.6 mlO 2/ /kg/min, respectively; p = 0.087). Bland-Altman plots for both methods showed a proportional bias for the non-BB group; but not the BB group. Our results suggest that sub-maximal protocols based on Borg's Rating of Perceived exertion (RPE) produce differing results from sub-maximal protocols based on HR response when applied to clinical population taking BB medications. Using RPE instead of HR for participants on BB medications may be a better method for assessing the exercise tolerance for estimating the cardiorespiratory capacity in sub-maximal exercise testing.

Objectives: We compared the diagnostic accuracy of 4 depression screening scales, using traditional and alternative scoring methods, to the gold standard Structured Clinical Interview-DSM IV major depressive episode (MDE) in ovarian cancer patients on active treatment., Methods: At the beginning of a new chemotherapy regimen, ovarian cancer patients completed the following surveys on the same day: the Center for Epidemiological Studies Depression Scale (CES-D), the Beck Depression Inventory Fast-Screen for Primary Care (BDI-FastScreen), the Patient Health Questionnaire-9 (PHQ-9), and a 1-item screener ("Are you depressed?"). Each instrument's sensitivity, specificity, positive predictive value (PPV) and negative predictive value were calculated with respect to major depression. To control for antidepressant use, the analyses were re-run for a subsample of patients who were not on antidepressants., Results: One hundred fifty-three ovarian cancer patients were enrolled into the study. Only fourteen participants met SCID criteria for current MDE (9%). When evaluating all patients regardless of whether they were already being treated with antidepressants, the two-phase scoring approach with an alternate cutpoint of 6 on the PHQ-9 had the best positive predictive value (PPV=32%). Using a traditional cutpoint of 16 on the CES-D resulted in the lowest PPV (5%); using a more stringent cutpoint of 22 resulted in a slightly improved but still poor PPV, 7%., Conclusions: Screening with a two-phase PHQ-9 proved best overall, and its accuracy was improved when used with patients who were not already being treated with antidepressants., (Copyright © 2017 Elsevier Inc.

Declining water quality is one of the main reasons of coral reef degradation in the Thousand Islands off the megacity Jakarta, Indonesia. Shifts in benthic community composition to higher soft coral abundances have been reported for many degraded reefs throughout the Indo-Pacific. However, it is not clear to what extent soft coral abundance and physiology are influenced by water quality. In this study, live benthic cover and water quality (i.e. dissolved inorganic nutrients (DIN), turbidity (NTU), and sedimentation) were assessed at three sites (< 20 km north of Jakarta) in Jakarta Bay (JB) and five sites along the outer Thousand Islands (20-60 km north of Jakarta). This was supplemented by measurements of photosynthetic yield and, for the first time, respiratory electron transport system (ETS) activity of two dominant soft coral genera, Sarcophyton spp. and Nephthea spp. Findings revealed highly eutrophic water conditions in JB compared to the outer Thousand Islands, with 44% higher DIN load (7.65 μM/L), 67% higher NTU (1.49 NTU) and 47% higher sedimentation rate (30.4 g m -2 d -1 ). Soft corals were the dominant type of coral cover within the bay (2.4% hard and 12.8% soft coral cover) compared to the outer Thousand Islands (28.3% hard and 6.9% soft coral cover). Soft coral abundances, photosynthetic yield, and ETS activity were highly correlated with key water quality parameters, particularly DIN and sedimentation rates. The findings suggest water quality controls the relative abundance and physiology of dominant soft corals in JB and may thus contribute to phase shifts from hard to soft coral dominance, highlighting the need to better manage water quality in order to prevent or reverse phase shifts., Competing Interests: The authors declare that they have no competing interests.

Jakarta Bay, next to the Jakarta Metropolitan Area with around 30 million inhabitants, is facing extreme pollution. Although local coral reefs are degraded and marine resources heavily exploited, they provide livelihoods for millions of people. This study investigates anthropogenic pressures on local fisheries resources and associated livelihoods. Questionnaire surveys were conducted in 15 coastal communities (10 coastal neighborhoods in Jakarta Bay on the mainland and 5 of the offshore Thousand Islands). The most economically valuable species were Caesio cuning (Redbelly yellowtail fusilier) on the islands and Rastrelliger kanagurta (Indian mackerel) on the mainland. Over 80% of all interviewed fishermen regarded the current state of marine resources as declining, mainly due to pollution and overexploitation. While perceptions of declining resources were equally high on the islands and the mainland, pollution was listed as the principal cause of degradation significantly more on the mainland. Findings are discussed in the context of coastal livelihood vulnerability., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

Jakarta Bay in Indonesia and its offshore island chain, the Thousand Islands, are facing extreme pollution. Surfactants and diesel-borne compounds from sewage and bilge water discharges are common pollutants. However, knowledge of their effects on reef fish physiology is scarce. This study investigated combined and single effects of a) the water accommodated fraction of diesel (WAF-D, determined by ƩEPA polycyclic aromatic hydrocarbons (PAHs)) and b) the surfactant linear alkylbenzene sulfonate (LAS) on metabolic performance of the coral reef fish Siganus guttatus. Responses to combinations of each pollutant with elevated temperature (+3°C) were determined. Short-term exposure to WAF-D led to a significant decrease in standard metabolic rates, while LAS led to an increase. During combined exposure, metabolic depression was observed. Effects of pollutants were not amplified by elevated temperature. This study highlights the need to reduce import of these pollutants and to avoid negative long-term effects on fish health., (Copyright © 2016 Elsevier Ltd. All rights reserved.)

Objective: Physical activity is beneficial for cancer survivors, but exercise participation is low in this population. It is therefore important to understand the psychological factors underlying exercise uptake so that more effective interventions can be developed. Social-cognitive theory constructs such as outcome expectancies predict exercise behavior, but self-report measures have several limitations. We examined the associations between implicit (automatic) cognitions and exercise behavior and self-efficacy in endometrial cancer survivors., Method: This was a longitudinal study to examine predictors of exercise behavior in female endometrial cancer survivors who all received an exercise intervention. Participants (N = 100, mean age of 57.0) completed questionnaires to assess self-report exercise-related measures (outcome expectancy and attitudes about and identification with exercise) and reaction time (RT) tasks to assess implicit exercise cognitions (expectancy accessibility, implicit attitudes about exercise, and implicit self-identification with exercise) at baseline and at 2, 4, and 6 months at follow-up. Exercise behavior was measured using accelerometers and self-report. Data were analyzed using linear mixed models., Results: Expectancy accessibility was associated with exercise duration independent of the corresponding self-report measure. Exercise implicit attitudes and self-identification were prospectively associated with exercise self-efficacy only after adjustment for the corresponding self-report measures and baseline self-efficacy. Self-report measures were also associated with study outcomes., Conclusions: Both self-reported cognitions and implicit cognitions may be useful to identify individuals at risk of failing to exercise. Individuals so identified might be provided with a different or more intensive intervention. The data also suggest cognitive targets for intervention.

Objectives: To evaluate prospectively the associations between illness uncertainty, anxiety, fear of progression and general and disease-specific quality of life (QoL) in men with favourable-risk prostate cancer undergoing active surveillance (AS)., Patients and Methods: After meeting stringent enrollment criteria for an AS cohort study at a single tertiary care cancer centre, 180 men with favourable-risk prostate cancer completed questionnaires at the time of enrollment and every 6 months for up to 30 months. Questionnaires assessed illness uncertainty, anxiety, prostate-specific QoL (using the Expanded Prostate Cancer Index Composite [EPIC] scale) and general QoL (using the 12-time short-form health survey [SF-12]) and fear of progression. We used linear mixed-model analyses and multilevel mediation analyses., Results: Sexual scores on the EPIC scale significantly declined over time (P < 0.05). Illness uncertainty was a significant predictor of all EPIC summary scores, SF-12 physical component summary (PCS) scores, mental component summary (MCS) scores and fear of progression scores (all P < 0.05), after controlling for demographic and clinicopathological factors. Anxiety predicted all EPIC summary, MCS and fear of progression scores (all P < 0.05) but not PCS scores (P = 0.08). Scores on PCS, MCS, EPIC summary scales (except sexual scale), and fear of progression did not change significantly over the study period (all P > 0.10)., Conclusion: Over the 2.5-year follow-up, QoL remained stable; only sexual function scores significantly declined. Illness uncertainty and anxiety were significant predictors of general and prostate-specific QoL and fear of progression. Interventions to reduce uncertainty and anxiety may enhance QoL for men with prostate cancer on AS., (© 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.)

Knowledge on interactive effects of global (e.g. ocean warming) and local stressors (e.g. pollution) is needed to develop appropriate management strategies for coral reefs. Surfactants and diesel are common coastal pollutants, but knowledge of their effects on hard corals as key reef ecosystem engineers is scarce. This study thus investigated the physiological reaction of Pocillopora verrucosa from Lombok, Indonesia, to exposure with a) the water-soluble fraction of diesel (determined by total polycyclic aromatic hydrocarbons (PAH); 0.69 ± 0.14 mg L-1), b) the surfactant linear alkylbenzene sulfonate (LAS; 0.95 ± 0.02 mg L-1) and c) combinations of each pollutant with high temperature (+3°C). To determine effects on metabolism, respiration, photosynthetic efficiency and coral tissue health were measured. Findings revealed no significant effects of diesel, while LAS resulted in severe coral tissue losses (16-95% after 84 h). High temperature led to an increase in photosynthetic yield of corals after 48 h compared to the control treatment, but no difference was detected thereafter. In combination, diesel and high temperature significantly increased coral dark respiration, whereas LAS and high temperature caused higher tissue losses (81-100% after 84 h) and indicated a severe decline in maximum quantum yield. These results confirm the hypothesized combined effects of high temperature with either of the two investigated pollutants. Our study demonstrates the importance of reducing import of these pollutants in coastal areas in future adaptive reef management, particularly in the context of ocean warming.

Objective: Research has shown that physical activity (PA) has a positive effect on cancer survivors, including improving quality of life, improving physical fitness, and decreasing risk for cancer recurrence in some cancer types. Theory-based intervention approaches have identified self-efficacy as a potential mediator of PA intervention. This study examines the temporal relationships at 4 time points (T1-T4) between several social-cognitive theory constructs and PA among a group of endometrial cancer survivors receiving PA intervention., Method: A sample of 98 sedentary women who were at least 6 months posttreatment for endometrial cancer were given interventions to increase their PA. We tested whether modeling, physiological somatic sensations, and social support at previous time points predicted self-efficacy at later time points, which in turn would predict PA at later time points., Results: Results indicated that, as physiological somatic sensations at T2 decreased, self-efficacy at T3 increased, which led to an increase in PA at T4. This suggests that self-efficacy is a significant mediator between physiological somatic sensations and PA. Exploratory follow-up models suggest that model fit can be improved with the addition of contemporaneous effects between self-efficacy and PA at T3 and T4, changing the timing of the mediational relationships., Conclusion: Physiological somatic sensations appear to be an important construct to target to increase PA in this population. Self-efficacy appeared to mediate the relationship between physiological somatic sensations and PA, but the timing of this relationship requires further study.

Worldwide, coral reefs are challenged by multiple stressors due to growing urbanization, industrialization and coastal development. Coral reefs along the Thousand Islands off Jakarta, one of the largest megacities worldwide, have degraded dramatically over recent decades. The shift and decline in coral cover and composition has been extensively studied with a focus on large-scale gradients (i.e. regional drivers), however special focus on local drivers in shaping spatial community composition is still lacking. Here, the spatial impact of anthropogenic stressors on local and regional scales on coral reefs north of Jakarta was investigated. Results indicate that the direct impact of Jakarta is mainly restricted to inshore reefs, separating reefs in Jakarta Bay from reefs along the Thousand Islands further north. A spatial patchwork of differentially degraded reefs is present along the islands as a result of localized anthropogenic effects rather than regional gradients. Pollution is the main anthropogenic stressor, with over 80% of variation in benthic community composition driven by sedimentation rate, NO2, PO4 and Chlorophyll a. Thus, the spatial structure of reefs is directly related to intense anthropogenic pressure from local as well as regional sources. Therefore, improved spatial management that accounts for both local and regional stressors is needed for effective marine conservation.

The COMPASS collaboration at CERN has investigated pion Compton scattering, π(-)γ→π(-)γ, at center-of-mass energy below 3.5 pion masses. The process is embedded in the reaction π(-)Ni→π(-)γNi, which is initiated by 190 GeV pions impinging on a nickel target. The exchange of quasireal photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, Q(2)<0.0015  (GeV/c)(2). From a sample of 63,000 events, the pion electric polarizability is determined to be α(π)=(2.0±0.6(stat)±0.7(syst))×10(-4)  fm(3) under the assumption α(π)=-β(π), which relates the electric and magnetic dipole polarizabilities. It is the most precise measurement of this fundamental low-energy parameter of strong interaction that has been addressed since long by various methods with conflicting outcomes. While this result is in tension with previous dedicated measurements, it is found in agreement with the expectation from chiral perturbation theory. An additional measurement replacing pions by muons, for which the cross-section behavior is unambiguously known, was performed for an independent estimate of the systematic uncertainty.

Purpose: This study assessed whether the Patient-Reported Outcomes Measurement Information System (PROMIS) computer-adaptive tests (CATs) provided results similar to those of the Brief Symptom Inventory (BSI) with a low patient burden., Methods: Secondary data analysis of 136 prostate cancer patients who completed the 53-item BSI and the PROMIS CATs assessing depression, anxiety, and hostility., Results: The PROMIS CATs and BSI correlated significantly in measures of depression (.85), anxiety (.76), and anger/hostility (.66; p < .001 for all). Using our BSI cutoff points for depression, anxiety, and anger/hostility, ROC analysis yielded areas under the curve of .966 [standard error (SE) = .014, p < .001], .975 (SE = .012, p < .001), and .952 (SE = .027, p < .001), respectively., Conclusions: PROMIS CATs were highly correlated with the BSI subscales, indicating that the CATs performed well compared with the BSI, a widely used psychosocial measure.

Objective: The objective of this paper is to describe baseline differences between obese and non-obese endometrial cancer survivor in anthropometrics, exercise behavior, fitness, heart rate and blood pressure, and quality of life, and to analyze whether the effect of a home-based exercise intervention on these outcomes differed for obese and non-obese participants., Methods: One hundred post-treatment Stage I-IIIa endometrial cancer survivors participated in a single arm 6month study in which they received a home-based exercise intervention. Cardiorespiratory fitness, anthropometrics, and exercise behavior were measured every two months, and quality of life (QOL) and psychological distress were measured at baseline and 6months., Results: Adjusting for potential confounders, at baseline obese survivors had poorer cardiorespiratory fitness (p=.002), higher systolic blood pressure (p=.018), and lower physical functioning (p<.001) and ratings of general health (p=.002), and more pain (p=.037) and somatization (.002). Significant improvements were seen in exercise behavior, resting heart rate, systolic blood pressure, and multiple QOL domains over the course of the intervention. Obese survivors had less improvement in exercise behavior and cardiorespiratory fitness than non-obese survivors, but there were no differences with regard to improvements in QOL and stress., Conclusions: Home based exercise interventions are beneficial to endometrial cancer survivors, including those whose BMI is in the obese range. While obese survivors have lower levels of physical activity and fitness, they experienced similar activity, fitness, quality of life and mental health benefits. Exercise should be encouraged in endometrial cancer survivors, including those who are obese., (Copyright © 2014 Elsevier Inc. All rights reserved.)

Background: To reduce the risk of long-term swallowing complications after radiation, swallowing exercises may be helpful. Both the rate of adherence to swallowing exercises and its impact on future swallowing function are unknown., Methods: In all, 109 patients with oropharyngeal cancer beginning radiation were tracked for 2 years to determine adherence to swallowing exercises. Participants completed the MD Anderson Dysphagia Inventory (MDADI) 1-2 years after treatment, to assess self-reported swallowing function. Adherence, demographics, tumor, and treatment variables were multivariably regressed onto the MDADI physical subscale score., Results: In accord with speech pathologist documentation, 13% of the participants were fully adherent and 32% were partially adherent. Adherence was associated with the Physical MDADI Subscale score in the multivariate model (p = .01)., Conclusions: The majority of patients with head and neck cancer are nonadherent to swallowing exercise regimens and may benefit from supportive care strategies to optimize their adherence., (Copyright © 2013 Wiley Periodicals, Inc.)

Objective: This study evaluated whether social-cognitive theory (SCT) variables, as measured by questionnaire and ecological momentary assessment (EMA), predicted exercise in endometrial cancer survivors., Method: One hundred posttreatment endometrial cancer survivors received a 6-month home-based exercise intervention. EMAs were conducted by using hand-held computers for 10- to 12-day periods every 2 months. Participants rated morning self-efficacy and positive and negative outcome expectations by using the computer, recorded exercise information in real time and at night, and wore accelerometers. At the midpoint of each assessment period, participants completed SCT questionnaires. Using linear mixed-effects models, the authors tested whether morning SCT variables predicted minutes of exercise that day (Question 1) and whether exercise minutes at time point Tj could be predicted by questionnaire measures of SCT variables from time point Tj-1 (Question 2)., Results: Morning self-efficacy significantly predicted that day's exercise minutes (p < .0001). Morning positive outcome expectations were also associated with exercise minutes (p = .0003), but the relationship was attenuated when self-efficacy was included in the model (p = .4032). Morning negative outcome expectations were not associated with exercise minutes. Of the questionnaire measures of SCT variables, only exercise self-efficacy predicted exercise at the next time point (p = .003)., Conclusions: The consistency of the relationship between self-efficacy and exercise minutes over short (same day) and longer (Tj to Tj-1) time periods provides support for a causal relationship. The strength of the relationship between morning self-efficacy and exercise minutes suggest that real-time interventions that target daily variation in self-efficacy may benefit endometrial cancer survivors' exercise adherence.

The COMPASS Collaboration at CERN has investigated the π- γ → π- π- π+ reaction at center-of-momentum energy below five pion masses, sqrt[s]<5m(π), embedded in the Primakoff reaction of 190 GeV pions impinging on a lead target. Exchange of quasireal photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, t'<0.001  GeV2/c2. Using partial-wave analysis techniques, the scattering intensity of Coulomb production described in terms of chiral dynamics and its dependence on the 3π-invariant mass m(3π)=sqrt[s] were extracted. The absolute cross section was determined in seven bins of sqrt[s] with an overall precision of 20%. At leading order, the result is found to be in good agreement with the prediction of chiral perturbation theory over the whole energy range investigated.

Background: African American breast cancer survivors may be at high risk for reproductive health problems, including menopause symptoms, sexual dysfunction, and distress about cancer-related infertility. The authors partnered with Sisters Network Inc. to create the Sisters Peer Counseling in Reproductive Issues After Treatment (SPIRIT) program, a culturally sensitive intervention program that combined a written workbook and peer counseling., Methods: Three hundred women were randomized to receive either the workbook plus 3 in-person sessions with a trained peer counselor or the workbook plus ≤ 30 minutes of telephone counseling to be initiated by the participant. Questionnaires at baseline, post-treatment, and at 6-month and 12-month follow-up assessed emotional distress, sexual function, relationship satisfaction, spirituality, menopause symptoms, and knowledge. Satisfaction with the program and the use of medical care also were assessed., Results: Both groups of women improved significantly in knowledge, decreased in distress, and had decreased hot flashes. Sexually active women had improved sexual function at 6-month follow-up but not at 1 year. However, peer counseling had little incremental benefit over the telephone counseling., Conclusions: The SPIRIT program was rated very useful by 66% of women. Outcomes justify continued use of the workbook and further research to optimize the impact of peer counseling., (Copyright © 2011 American Cancer Society.)

Background: Adjusting to cancer requires effective cognitive and emotional processing. Written and verbal disclosure facilitate processing and have been studied independently in cancer survivors. Combined written and verbal expression may be more effective than either alone, particularly for patients with difficult to discuss or embarrassing side effects. Thus, the authors developed and tested the efficacy of a 12-session combined written and verbal expression group program for psychologically distressed colorectal cancer (CRC) patients., Methods: Forty post-treatment patients with CRC (stages I-III) identified as psychologically distressed using the Brief Symptom Inventory (BSI) were randomized to an intervention group (Healthy Expressions; n = 25) or standard care (control group; n = 15). Assessments were completed at baseline, Month 2, and Month 4 (postintervention). Primary outcomes were psychological functioning and quality of life (QOL)., Results: Most participants were women (63%), white (63%), and non-Hispanic (75%). The Healthy Expressions group demonstrated significantly greater changes in distress compared with the control group at Month 2 on the BSI Global Severity Index (GSI) and the Centers for Epidemiologic Studies Depression scale (CES-D) scores (P < .05 for each); differences in the European Organization for Research and Treatment of Cancer (EORTC) global QOL scores approached significance (P = .063). The BSI GSI and Positive Symptom Total, CES-D, and EORTC emotional functioning subscale scores were all significant at Month 4 (P < .05 for each)., Conclusions: The Healthy Expressions program improved psychological functioning in CRC patients who reported experiencing distress. Findings demonstrate the program's feasibility and provide strong support for conducting a larger randomized trial., (Copyright © 2011 American Cancer Society.)

Background: Self-efficacy can be affected by mastery experiences and somatic sensations. A novel exercise experience and associated sensations may impact self-efficacy and subsequent behaviors. We investigated the effect of a single exercise session on self-efficacy for sedentary endometrial cancer survivors compared with sedentary women of a similar age, but with no cancer history., Methods: Twenty survivors and 19 controls completed an exercise session performed as a submaximal cycle ergometry test. Sensations and efficacy were measured before and after exercise. Repeated measures analysis of variance (ANOVA) was performed. Regression models were used to determine predictors of self-efficacy and subsequent exercise., Results: Self-efficacy increased for both survivors and controls, but survivors had a higher rate of increase, and the change predicted subsequent exercise. The association between exercise-related somatic sensations and self-efficacy differed between the 2 groups., Conclusions: A novel exercise experience had a larger effect on self-efficacy and subsequent exercise activity for endometrial cancer survivors than controls. Somatic sensations experienced during exercise may differ for survivors, which may be related to the experience of having cancer. Understanding factors affecting confidence in novel exercise experiences for populations with specific cancer histories is of the utmost importance in the adoption of exercise behaviors.

The COMPASS experiment at the CERN SPS has studied the diffractive dissociation of negative pions into the π- π- π+ final state using a 190  GeV/c pion beam hitting a lead target. A partial wave analysis has been performed on a sample of 420,000 events taken at values of the squared 4-momentum transfer t' between 0.1 and 1  GeV2/c2. The well-known resonances a1(1260), a2(1320), and π2(1670) are clearly observed. In addition, the data show a significant natural-parity exchange production of a resonance with spin-exotic quantum numbers J(PC)=1-+ at 1.66  GeV/c2 decaying to ρπ. The resonant nature of this wave is evident from the mass-dependent phase differences to the J(PC)=2-+ and 1++ waves. From a mass-dependent fit a resonance mass of (1660±10(-64)(+0))  MeV/c2 and a width of (269±21(-64)(+42))  MeV/c2 are deduced, with an intensity of (1.7±0.2)% of the total intensity.

Gaucher's disease, a lysosomal storage disorder caused by mutations in the gene encoding glucocerebrosidase (GCD), is currently treated by enzyme replacement therapy using recombinant GCD (Cerezyme) expressed in Chinese hamster ovary (CHO) cells. As complex glycans in mammalian cells do not terminate in mannose residues, which are essential for the biological uptake of GCD via macrophage mannose receptors in human patients with Gaucher's disease, an in vitro glycan modification is required in order to expose the mannose residues on the glycans of Cerezyme. In this report, the production of a recombinant human GCD in a carrot cell suspension culture is described. The recombinant plant-derived GCD (prGCD) is targeted to the storage vacuoles, using a plant-specific C-terminal sorting signal. Notably, the recombinant human GCD expressed in the carrot cells naturally contains terminal mannose residues on its complex glycans, apparently as a result of the activity of a special vacuolar enzyme that modifies complex glycans. Hence, the plant-produced recombinant human GCD does not require exposure of mannose residues in vitro, which is a requirement for the production of Cerezyme. prGCD also displays a level of biological activity similar to that of Cerezyme produced in CHO cells, as well as a highly homologous high-resolution three-dimensional structure, determined by X-ray crystallography. A single-dose toxicity study with prGCD in mice demonstrated the absence of treatment-related adverse reactions or clinical findings, indicating the potential safety of prGCD. prGCD is currently undergoing clinical studies, and may offer a new and alternative therapeutic option for Gaucher's disease.

First measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarized 6LiD target are presented. The data were taken in 2002 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. The Collins asymmetry turns out to be compatible with zero, as does the measured Sivers asymmetry within the present statistical errors.

Study Objective: To apply the Arkansas color method in order to evaluate drug compliance and factors that can predict treatment adherence in patients being treated for latent tuberculosis infection (LTBI) with a single daily dose of isoniazid (INH)., Design: Prospective study of adherence of 105 patients aged 1 to 75 years who were treated with a single daily dose of INH for LTBI., Interventions: Patients or their parents were interviewed regarding parameters that may affect compliance. Urine samples were collected and tested for INH metabolites with the Arkansas color method., Results: Nonadherence to treatment was found in 28.5% of patients. There was no statistically significant correlation among the following parameters: gender; age; diagnosis; mode of administration (self or parents); duration of treatment; dose of INH per weight; or interval since last intake of dose. Twenty-six patients were randomly checked for treatment adherence on two separate visits, and nonadherent patients were informed immediately and their condition was fully explained to them. Five of six patients who were nonadherent in the first visit and were examined twice became adherent in the second visit. Three of 20 patients who were adherent in the first visit became nonadherent., Conclusion: Almost one third of the patients who received LTBI treatment with INH were nonadherent to treatment. No factor was found to predict adherence. The Arkansas method can be used by the family physician and is a simple, immediate method to follow-up patients with LTBI who are treated with INH.

The study identified barriers to research implementation experienced by nurses, midwives and health visitors in five trusts and one health authority in Yorkshire, UK. Funk et al. (Appl. Nurs. Res. 4(1) (1991a) 39, Appl. Nurs. Res. 4(2) (1999b) 90) developed the BARRIERS to research utilisation questionnaire over 10 years ago, but no replication, in size (n = 1989) and extent, of that study appeared to have occurred. The staff population (n = 4501) were sent the BARRIERS questionnaire. 44.6% (n = 2009) were returned. Findings suggested nurses need time to read and apply research; authority to change practice; critical appraisal skills, an understanding of statistics and support of managers and peers (particularly doctors) to achieve successful practice change., (Copyright 2002 Elsevier Science Ltd.)

Molecules of the title compound, [Cu(C(2)H(3)N)(C(11)H(9)N(5))(C(6)H(6)N(2)O)](BF(4))(2).2C(2)H(3)N, comprise (acetonitrile)[2,6-bis(pyrazol-1-yl)pyridine](isonicotinamide)copper(II) cations, tetrafluoroborate anions and lattice acetonitrile molecules. The cations have distorted square-pyramidal geometries in which the N(3)-donor, viz. 2,6-bis(pyrazol-1-yl)pyridine, and the N-donor, viz. the isonicotinamide ligand, occupy the four basal positions, with the coordinated acetonitrile N-donor atom occupying the apical position. Pairs of cations are linked by N-H.F hydrogen bonds through tetrafluoroborate anions, forming centrosymmetric dimers, which are further linked by C-H.O hydrogen bonds into two-dimensional undulating sheets, three of which interpenetrate to generate a two-dimensional network.

Background: Large numbers of convicted drunk drivers are entering alcohol treatment programs, yet little information is available about their need for psychiatric treatment. This study of convicted drunk drivers estimates lifetime and 12-month prevalence of DSM-III-R psychiatric disorders (alcohol and drug abuse and dependence, major depressive disorder, dysthymic disorder, generalized anxiety disorder, posttraumatic stress disorder, and antisocial personality disorder) and compares rates with estimates from a US population-based survey., Methods: Six hundred twelve women and 493 men, aged 23 to 54 years, convicted of driving while impaired, who had been referred to a screening program in Bernalillo County, New Mexico, were located and interviewed using the Diagnostic Interview Schedule between January 25, 1994, and June 30, 1997. Psychiatric diagnoses were compared with findings from the National Comorbidity Survey for the western region of the United States, conducted between September 14, 1990, and February 6, 1992., Results: Eighty-five percent of female and 91% of male offenders reported a lifetime alcohol-use disorder, compared with 22% and 44%, respectively, in the National Comorbidity Survey sample. Thirty-two percent of female and 38% of male offenders had a drug-use disorder, compared with 16% and 21%, respectively, in the National Comorbidity Survey sample. For offenders with alcohol-use disorders, 50% of women and 33% of men had at least 1 additional psychiatric disorder other than drug abuse or dependence, mainly posttraumatic stress disorder or major depression., Conclusion: Drunk-driving offenders need assessment and treatment services not only for alcohol problems but also for drug use and the other psychiatric disorders that commonly accompany alcohol-related problems.

Coordination of the pentatopic ligand 3 with AgI leads to the simultaneous self-assembly of two polynuclear architectures: a [4 x 5] grid-type species 10 and a quadruple-helicate 11, which contain twenty and ten silver ions. respectively. Their structures have been established by X-ray diffraction analysis of the crystals obtained as a mixture on crystallisation. Complex 10 contains two [2 x 5]-AgI10 rectangular subgrids located on opposite sides of an array of parallel ligands of 3 that are twisted into a transoid N=C-C=N arrangement around the central C-C bond; it may thus be formulated as a grid of grids: [2 x (2 x 5)]. Complex 11 is an inorganic quadruple helicate that consists of two sets of two parallel ligands of 3 connected by an array of ten silver ions. Both compounds 10 and 11 are novel types of polynuclear complexes that are composed of two subunits. Their formation points to the possibility of generating specific arrays of metal ions by self-assembly, involving, in particular, a combination of subunits within the overall entity. They represent organised patterns of ion dots of special significance in view of their formal relationship to quantum dots.

The synthesis and X-ray structures of three metal complexes with terpyridine-derived ligands that contain amino-pyrimidine and amino-pyrazine moieties are presented. They have been designed in view of directing their self-assembly into specific supramolecular arrays through molecular recognition interactions. The solid-state structures indeed reveal extensive hydrogen-bonded networks. The Co complex 4a with PF6- counterions builds a two-dimensional infinite interwoven grid through strong double hydrogen bonds (d(N-H-N) =2.918-3.018 A) between the amino groups and the N atoms of the rings, with all H-bonding sites saturated. Changing the anions to BF4- in 4b leads to a similar infinite but partially broken grid with a quarter of the H-bonding sites unsaturated (d(N-H-N)=2.984-3.206 A). In the case of the Zn complex 12 with triflate anions, half of the hydrogen bonds are formed. Only one of the two orthogonal ligands has hydrogen bonds (d(N-H-N) = 3.082, 3.096 A) to the neighbouring complexes and thus builds linear, supramolecular, polymeric chains. These structural differences are mainly attributed to crystal-packing effects caused by the different anions. The data presented here may also be regarded as a prototype for the generation of organised arrays through sequential self-assembly processes.
