Abstract
INTRODUCTION This study reviews our cumulative experience with the management of patients presenting with a retained knife following an abdominal stab wound (SW). METHODS A retrospective study was conducted at a major trauma centre in South Africa over a 15-year period from July 2006 to December 2020 including all patients who presented with a retained knife in the abdomen following a SW. RESULTS A total of 42 cases were included: 37 males (93%) with a mean age of 26 years. A total of 18 knives (43%) were in the anterior abdomen and 24 were posterior abdomen. Plain radiography was performed in 88% (37/42) of cases and computed tomography was performed in 81% (34/42); 90% (38/42) underwent extraction in the operating theatre. Laparotomy was performed in 62% (26/42). Of all the laparotomies performed, 77% (20/26) were positive for intra-abdominal organ or visceral injury. Overall morbidity was 31%. There were two mortalities (5%). Laparotomy was less commonly required for the posterior abdomen (33% (8/24) vs 100% (18/18), p<0.001). For retained knives in the anterior abdomen, 72% (13/18) of the laparotomies were positive for intra-abdominal organ or visceral injury. For the posterior abdomen, 7 of the 8 (88%) were positive for intra-abdominal organ or visceral injury. There were no differences in the need for intensive care unit admission, length of hospital stay, morbidities or mortalities. CONCLUSIONS Uncontrolled extraction of a retained knife in the abdomen outside of the operating theatre must be avoided. Retained knives in the anterior abdomen usually require formal laparotomy, but this is generally not required for posterior abdomen.

Abstract
BACKGROUND This paper reviews our experience with management of renal injuries in children and adolescents with a focus on the outcome of non-operative management (NOM). METHODS Retrospective review of the clinical characteristics, injury grade (I-III, low grade and IV and V high grade), management and outcomes of children ≤ 18 years old with renal trauma presenting to a major trauma centre in South Africa between December 2012 and October 2020. RESULTS Sixty-one children with a renal injury were identified with a median age of 13 (range 0-18) years. Forty-five were boys; blunt and penetrating mechanisms of trauma were sustained by 55 (90%) and six (10%) children, respectively. The median American Association for the Surgery of Trauma (AAST) grade of renal injury was 3 (range 1-5): this included eight (13%) with grade I, six (10%) with grade II, 17 (28%) with grade III, 20 (46%) with grade IV and 10 (16%) with grade V injuries. Forty children (66%) were successfully managed non-operatively and 21 required a laparotomy; of these six (28%) required nephrectomy. The overall renal salvage rate was 55/61 (90%). Children who required laparotomy were significantly more likely to have sustained a penetrating mechanism of injury (24% vs 2%) and have greater length of hospital stay (median 9 vs 3 days) compared to children managed non-operatively (p < 0.05). Children who underwent a nephrectomy had a significantly greater length of hospital stay (median 9 vs 4 days, p = 0.03); however, their demographics, outcomes developed complications. Two children (3%) died; one managed non-operatively and one with a laparotomy. CONCLUSION Paediatric renal trauma can be successfully managed non-operatively in over two-thirds of cases in this middle-income country. High grade of renal injury does not absolutely predict need for surgery or nephrectomy and can be managed non-operatively.

Abstract
BACKGROUND Geriatric injuries comprise a significant burden in the developed world but much less are known in the developing world setting. This study aims to review our experience of geriatric injuries with a focus on interpersonal violence (IPV) managed at a major trauma centre in South Africa. METHODS This was a retrospective study on all patients who were aged > 65 years admitted to our trauma centre from January 2013 to December 2020, based in Pietermaritzburg, South Africa. RESULTS Over the 8-year study period, 323 cases were included (62% male, mean age 72 years). Mechanism of injury: 80% blunt, 16% penetrating and 4% others. The median injury severity score (ISS) was 9. The median Charlson comorbidity index (CCI) for all 323 cases was 3. Diabetes (n = 53) was the most prevalent comorbidity which was followed by pulmonary disease (n = 23), cerebral vascular accidents (n = 16) and myocardial infarction (n = 15). Fifteen patients were on antiretroviral therapy (5%). Twenty-four per cent required surgical intervention. Eight per cent of cases experienced one or more complications. Twenty-five per cent (80/323) were related to IPV, 61% (49/80) of these were penetrating injuries and the remaining 31 cases were blunt injuries. Of the 49 cases of penetrating injuries, 33 were gunshot wounds (GSWs) and 16 were stab wounds (SWs) (1 GSW and 2 SWs were self-inflicted and were not included in IPV). Those cases that resulted from IPV were significantly more likely to require operative intervention, experience complications and longer lengths of hospital stay. Geriatric patients had poorer outcomes than non-geriatric patients and rural geriatric patients had worse outcomes than urban geriatric patients. CONCLUSION Although the burden of geriatric trauma in South Africa appears to be relatively low, it is associated with significant morbidity and mortality. Trauma from interpersonal violence is especially common and is associated with significantly worse outcomes than that of non-interpersonal violence-related trauma. Elderly rural trauma victims have worse outcomes than their urban counterparts.

Abstract
BACKGROUND This study reviews the indications and outcome of emergency laparotomy for paediatric trauma in a South African trauma centre. METHODS This was a retrospective study of all children less than 18 years of age who underwent an emergency laparotomy for trauma between December 2012 and October 2020 at Grey's Hospital in Pietermaritzburg. RESULTS During the eight-year period under review, a total of 136 children of which 107 were male underwent a laparotomy for trauma. The median age was 14 years. There were 80 (57.1%) blunt mechanisms, and the rest were penetrating mechanisms. A total of 46 (33%) patients required ICU admission. Thirty-four patients developed a complication. These included nine cases of pneumonia, one case of renal failure, two patients developed abdominal collections, three woundrelated complications, three neurological complications and one miscellaneous complication. There were seven (5%) deaths. The penetrating cohort were older than the blunt cohort. Solid viscera were more likely to be injured in the blunt cohort and hollow viscera more likely in the penetrating cohort. A total of 16 (11%) patients underwent damage control surgery (DCS). Of this cohort, there were three female children. Six sustained blunt trauma and ten penetrating trauma. A total of six (37%) of these children died. CONCLUSION Emergency laparotomy for trauma in children is not infrequent in Pietermaritzburg and there is a high incidence of penetrating trauma in this cohort. The response to increased degrees of physiological derangement is the application of DCS. Ongoing efforts to develop and strengthen a paediatric trauma service appear to be justified.

Abstract
Hatha yoga (HY) and aerobic and strengthening exercise (ASE) programs are recommended for optimal management of osteoarthritis. However, evidence on long-term adherence to these programs and factors that influence it is lacking in older adults. The purposes of this study were to (1) describe and compare long-term HY and ASE adherence in community-dwelling older women with knee osteoarthritis 12 months post-HY/ASE intervention programs; (2) identify benefits and facilitators of, and barriers to, long-term adherence; and (3) examine other self-care interventions used after completing HY or ASE programs. Adherence was defined as following the prescribed HY/ASE program or incorporating the practice into daily habits. Five semistructured focus group interviews and 12 months of exercise diaries were obtained from 28 women (mean age 71.2 years). Long-term adherence to the prescribed HY or ASE regimen was relatively high, albeit adapted to individual needs, priorities, and preferences. Over the 12-month follow-up period, participants spent on average 3.5 days/3.1 hours per week on exercise. Most participants remained physically active by modifying their prescribed programs and integrating elements of the interventions into their own exercise regimens. Facilitators to long-term adherence were perceived benefits, having an exercise routine/habit, and program structure/instruction. Poor health status, lack of time, and exercise preferences were identified as barriers. Participants used a variety of self-care interventions including oral supplements and alternative diets for managing their osteoarthritis. This work suggests that exercise programs for osteoarthritis that incorporate individual preferences, flexible hours, and easy-to-follow instructions are most likely to result in long-term adherence.

Abstract
INTRODUCTION This study reviews our experience with the management a retained knife in the setting of thoracic stab wounds. METHODS A retrospective study was conducted at a major trauma in South Africa over a 15-year period from January 2004 to December 2018. RESULTS There were 40 patients, of whom 37 were males (93%). Median age was 24 years; 78% of cases (31 of 40) were a retained knife and 23% (9 of 40) were a retained blade. The locations of the stab wounds were 19 (48%) anterior and 21 (53%) posterior. Plain x-ray was performed in 85% (34) of patients and computed tomography angiography was performed in 85% (34). Six patients had haemodynamic instability and were expedited to the operating room without further imaging. Three of these had cardiac tamponade and three a massive haemothorax. Simple extraction and wound exploration were performed in 58% (23 of 40) of cases and the remaining 43% (17 of 40) required operative exploration and extraction. The operative approach was anterolateral thoracotomy in nine cases, posterolateral thoracotomy in four and median sternotomy in three cases. One patient required extraction and concurrent vertebral laminectomy due to cord compression. Twelve patients (30%) experienced complications (nine wound sepsis and three hospital-acquired pneumonia). There was one mortality (3%). The median length of hospital stay was 6 days. CONCLUSION Uncontrolled extraction of a retained thoracic knife outside the operating room must be avoided. An unstable patient should proceed directly for operative exploration. For stable patients, cross-sectional imaging will allow for planned extraction in operating room.

Abstract
Abstract
Cardiovascular complications are often the fundamental causes of death in non-alcoholic fatty liver disease (NAFLD) patients. While there are known systemic mediators in NAFLD that may induce vascular inflammation, the mechanism of endothelial dysfunction remain understudied. In this work, we harnessed the replicative potential of blood outgrowth endothelial cells (BOECs) to develop personalized cell lines from NAFLD patients and healthy controls. Our transcriptomic analysis showed that the top interactome network enriched in NAFLD BOECs comprised of several C-C and C-X-C chemokine ligands involved in immune cell chemotaxis. We previously reported T cell infiltration in mouse model of non-alcoholic steatohepatitis, and here, we confirmed enhanced endothelial chemokine signatures in arterial histological sections. To elucidate endothelial-immune crosstalk, we performed single-cell analysis on human peripheral blood mononuclear cells and found T cell intensification in NAFLD patients compared to healthy controls. Our immunoprofiling by flow cytometry further revealed that NAFLD patients possessed higher levels CD8+ memory cells. Functionally, T cells, instead of monocytes, adhered more pronouncedly to NAFLD BOECs. In evaluating the CXCL12-CXCR4 axis in chemotaxis, CXCR4 antagonist (AMD3100) substantially modulated the migration of patient-derived CD8+ T cells towards NAFLD BOECs, which was not observed in healthy endothelial-T cell chemotaxis coculture. Finally, we validated NAFLD-associated endothelial dysfunction by enumerating two folds more circulating endothelial cells, a biomarker of vascular injury, in the blood samples of NAFLD patients than healthy controls. Our work provides insights for translation to restore blood vessel health and potentially mitigate adverse vascular events in NAFLD.

Abstract
The first direct experimental observation of an electric quadrupole (E2) absorption transition between bound states of an atomic negative ion has been made. The transition was observed in the negative ion of bismuth by resonant (1+1) photon detachment from Bi^{-} via ^{3}P_{2}→^{3}P_{0} excitation. The E2 transition properties were completely independently calculated using a hybrid theoretical approach to account for the strong multilevel electron interactions and relativistic effects. The experimental and ab initio theoretical results are in excellent agreement, providing valuable new insight into this complex system and forbidden transitions in negative ions more generally.

Abstract
BACKGROUND In the United States, people over the age of 65 years will account for 20% of the population by 2030, and these elders are more likely to have chronic comorbid complex health problems. Sixty-three percent use complementary health approaches (CHAs) but less than half disclose their use to their health care providers. Nurse practitioners (NPs) are the fastest growing population of primary care health providers. PURPOSE This study identifies to what degree NPs with specialized training in geriatrics understand CHAs, use them themselves, encourage their patients to access them, and engage in CHA clinical dialogue. METHODS Cross-sectional online survey collecting quantitative and narrative data; US NPs with specialized training in geriatrics (n = 170, mean age 52 years, SD: 9.0, range: 29-73). RESULTS Although NPs are knowledgeable about some CHA and believe they are beneficial for older adults to use, they want more education to help understand the effects of a variety of CHA, be more aware of possible treatment interactions, and to integrate CHA into the current health care system. Patient factors (impaired cognitive function, acute health problems, and not open to CHA), provider factors (inadequate CHA knowledge, limited referral paths and resources), and system factors (limited accessibility and availability of CHA in in-patient setting, CHA not covered by insurance, and limited clinical time) disrupt NPs from assessing and discussing CHA with their patients. IMPLICATIONS FOR PRACTICE There is a need to develop and implement NP practice guidelines for CHA clinical management for older adults and provide educational opportunities to incorporate CHA into clinical practice.

Abstract
Background and purpose Complementary therapies, such as yoga, have been proposed to address gait and balance problems in Parkinson's disease (PD). However, the effects of yoga on gait and static balance have not been studied systematically in people with PD (PWP). Here we evaluated the effects of a 12-week long Hatha yoga intervention on biomechanical parameters of gait and posture in PWP. Methods We employed a pilot randomized controlled trial design with two groups of mild-to-moderate PWP (immediate treatment, waitlist control; N = 10 each; Mean Hoehn and Yahr score = 2 for each group). Baseline Unified Parkinson's Disease Rating Scale (UPDRS) motor scores, and gait and postural kinematics including postural sway path length, cadence, walking speed, and turning time were obtained. The immediate treatment group received a 60-min Hatha yoga training twice a week for 12 weeks, while the waitlisted control group received no training. After 12 weeks, gait and postural kinematics were assessed (post-test for treatment group and second-baseline for waitlist group). Then, the waitlist group received the same yoga training and was evaluated post-training. Results After Hatha yoga training, UPDRS motor scores improved with an 8-point mean decrease which is considered as a moderate clinically important change for mild-moderate PD. Sway path length during stance decreased significantly (mean reduction: -34.4%). No significant between-group differences or improvements in gait kinematics were observed. Conclusion This study showed that a 12-week Hatha yoga training can improve static balance in PWP. We found no evidence that it systematically improves gait performance in PWP.

Abstract
We develop a broadly applicable approach that drastically increases the ability to predict the properties of complex atoms accurately. We apply it to the case of Ir^{17+}, which is of particular interest for the development of novel atomic clocks with a high sensitivity to the variation of the fine-structure constant and to dark matter searches. In general, clock transitions are weak and very difficult to identify without accurate theoretical predictions. In the case of Ir^{17+}, even stronger electric-dipole (E1) transitions have eluded observation despite years of effort, raising the possibility that the theoretical predictions are grossly wrong. In this work, we provide accurate predictions of the transition wavelengths and E1 transition rates for Ir^{17+}. Our results explain the lack of observations of the E1 transitions and provide a pathway toward the detection of clock transitions. The computational advances we demonstrate in this work are widely applicable to most elements in the periodic table and will allow us to solve numerous problems in atomic physics, astrophysics, and plasma physics.

Abstract
UNLABELLED RANKL-OPG should be explored in DMD patients to potentially provide targeted therapy. We quantified RANKL and OPG levels in DMD patients compared with controls. RANKL, OPG, and RANKL:OPG significantly declined with age in DMD patients suggesting some bone turnover markers are difficult to assess or use as therapeutic indicators. INTRODUCTION Osteoporosis in Duchenne muscular dystrophy (DMD) is multi-factorial in nature with high prevalence of fractures. RANKL-OPG should be explored to potentially provide targeted therapy for these patients. We quantified RANKL, OPG, and RANKL:OPG levels in DMD patients compared with controls and analyzed the influence of age, glucocorticoid use, ambulatory status, bone density, and fracture history. METHODS DMD patients were enrolled at CHLA. Controls were recruited from general pediatric clinic and in collaboration with samples from a previously completed study. Free soluble RANKL and OPG levels were quantified using a sandwich ELISA. RESULTS Fifty DMD patients and 50 controls were enrolled. DMD patients had a significant decline in RANKL, OPG, and RANKL:OPG with age (p = < 0.0001, p = 0.026, and p = 0.002, respectively) while healthy controls showed no significant change. RANKL trended lower in patients on glucocorticoids (p = 0.05), attributed to the significantly older age in the treatment group. RANKL and RANKL:OPG levels were significantly lower in the non-ambulatory group compared with the ambulatory group (p = 0.010 and 0.036 respectively), again likely due to their older age. There was no correlation of RANKL, OPG, or RANKL:OPG with DXA Z-score or presence of vertebral fractures. CONCLUSION There was significant decline in RANKL, OPG, and RANKL:OPG with age in DMD patients compared with controls, potentially due to disease severity or worsening osteoblastic function. This suggests some bone turnover markers may be difficult to assess or use as therapeutic indicators in DMD patients. Larger studies are needed to evaluate the role of RANKL-OPG in DMD patients to provide better targeted therapy.

Abstract
BACKGROUND Lifestyle wellness programs help prevent and manage chronic diseases, yet few are designed for aging adults. PURPOSE Identify characteristics associated with aging adults' preferences for wellness program activities and delivery characteristics. SUBJECTS/METHODS Cross-sectional, self-administered survey of a convenience sample of 386 adults aged ≥55 years. Logistic regression models identified characteristics influencing preferences. RESULTS Current healthy behaviors, gender, and age influenced many preferences, while BMI, multiple chronic conditions, self-rated general health status, and quality of life did not. DISCUSSION Incorporating aging adults' preferences for wellness programs will help design appealing and engaging programs.

Abstract
Preliminary research indicates that yoga could be a valuable tool for people suffering from Parkinson's disease (PD). However, little has been published about the process by which the yoga interventions were designed and evaluated. This study elaborates on the process of developing and testing a bi-weekly, 12-week yoga program to determine its safety and feasibility for people with PD. The lead yoga teacher used input from a focused literature review to design an initial draft of the intervention program. This draft was reviewed by a group of yoga experts ( n = 6) to develop the final intervention program. This 12-week intervention was implemented in 19 participants with PD (mean age 63 ± 8, range 49-75) via twice-weekly yoga classes. Through this comprehensive development process, a series of 24 individual 1-hour yoga sequences was created. These sequences included yoga postures (asana), breathing techniques (pranayama), and mindfulness meditation principles specifically chosen to address concerns unique to the PD population. The feasibility of the program was supported with excellent attendance: 90% of participants attended > 75% of the classes, with four participants attending 100%. No adverse events were reported. This development process produced a safe and enjoyable yoga program specific for the needs of people with PD. However, this methodology could serve as a template for future studies on how to develop safe and effective yoga interventions for other populations.

Abstract
Objective To examine the feasibility, acceptability, and preliminary effects of Hatha yoga on oxidative stress, motor function, and non-motor symptoms among individuals with Parkinson's disease (PD). Methods The study has a pilot randomized controlled trial design with two arms: an immediate treatment group and a wait-list control group. The yoga-for-PD program was implemented via twice weekly 60-min group-based classes for 12 weeks. Participants were assessed at baseline, 12 weeks, and 6 months post-intervention. Outcome measures included oxidative stress, motor function, physical activity, cognitive function, sleep quality, and quality of life. Data on program acceptability and yoga adherence were collected during the intervention and at 6 months post-intervention. Results Participants (n = 20) had a mean age of 63 years (SD 8, range 49-75) and disease duration 4.8 years (SD 2.9, range 1-13). All participants had mild-moderate disease severity; 18 (90%) were on dopaminergic medications. Seventeen participants (85%) attended at least 75% of the classes and 4 (20%) attended all classes. Most participants (n = 17) reported they "definitely enjoyed" the intervention program. No adverse events were reported. At 12 weeks, there were no major differences in blood oxidative stress markers between the two groups. Motor function based on the Unified Parkinson's Disease Rating Scale was better in the treatment group, but their scores on sleep and outlook in Parkinson's Disease Quality of Life (PDQUALIF) Scale and the physical activity levels based on the Longitudinal Aging Study Amsterdam Physical Activity Questionnaire were worse than those of the control group. In within-group comparisons, motor function, cognitive function, and catalase improved but three PDQUALIF domains (social and role function, sleep, and outlook) and physical activity level worsened by the end of the yoga intervention program compared to baseline. The response rate for the 6-month follow-up survey was 74% (n = 14) with six participants (43%) who signed up for a yoga class and four (29%) who practiced it independently. Health problems were the main barrier to yoga practice. Conclusion Yoga is feasible and acceptable and may serve as a complementary method for improving motor function in PD. Further research using a larger sample size is needed to determine its impact on oxidative stress and non-motor symptoms. Trial registration ClinicalTrials.gov Registration Number: NCT02509610031.

Abstract
BACKGROUND Whilst preterm-born individuals have an increased risk of developing attention-deficit/hyperactivity disorder (ADHD), and are reported to have ADHD-like attention and arousal impairments, direct group comparisons are scarce. METHODS We directly compared preterm-born adolescents (n = 186) to term-born adolescents with ADHD (n = 69), and term-born controls (n = 135), aged 11-23, on cognitive-performance, event-related potential and skin conductance level (SCL) measures associated with attention and arousal. The measures are from baseline and fast-incentive conditions of a four-choice reaction time task, previously shown to discriminate between the individuals with ADHD and controls. We aimed to establish whether preterm-born adolescents show: (a) identical cognitive-neurophysiological impairments to term-born adolescents with ADHD (b) possible additional impairments, and whether (c) the observed impairments correlate with ADHD symptom scores. RESULTS The preterm group, like the term-born ADHD group, showed increased mean reaction time (MRT) and reaction time variability (RTV) in the baseline condition, and attenuated contingent negative variation (CNV) amplitude (response preparation) in the fast-incentive condition. The preterm group, only, did not show significant within-group adjustments in P3 amplitude (attention allocation) and SCL (peripheral arousal). Dimensional analyses showed that ADHD symptoms scores correlated significantly with MRT, RTV and CNV amplitude only. CONCLUSIONS We find impairments in cognition and brain function in preterm-born adolescents that are linked to increased ADHD symptoms, as well as further impairments, in lack of malleability in neurophysiological processes. Our findings indicate that such impairments extend at least to adolescence. Future studies should extend these investigations into adulthood.

Abstract
INTRODUCTION Primary dysmenorrhea is a prevalent condition causing quality of life (QOL) reduction for many women, resulting from pain as well as parallel social and psychological distress. Yoga reduces pain and sympathetic reactivity, thus promoting QOL. This article reports a systematic review of the evidence for the effectiveness of yoga as a QOL improvement method for women with primary dysmenorrhea. METHODS The PRISMA guidelines were used in preparation of this review. Ovid MEDLINE, PsycINFO, CINAHL, Scopus, PubMed, ScienceDirect, Cochrane Database of Systematic Reviews (CDSR), and Cochrane Central Register of Controlled Trials (CENTRAL) were screened through January 2017 using the keywords yoga, meditation, menstrual cycle, dysmenorrhea, pelvic pain, and prostaglandins. English-language randomized controlled trials (RCTs) and quasi-experimental studies regarding yoga, primary dysmenorrhea, and QOL were eligible; all yoga styles were included. Two independent reviewers rated the methodological quality of each study selected for review using the Downs and Black checklist; possible scores ranged from 0 to 32. Ratings were established through consensus. RESULTS The search yielded a total of 378 articles, of which 14 (age range 13-45 years, N = 1409) met the criteria for final review: 8 RCTs and 6 quasi-experimental studies. Downs and Black ratings were predominantly moderate in quality with moderate risk of bias, ranging from 15 to 23 (RCTs) and 10 to 17 (quasi-experimental studies). Statistically significant improvements along most QOL domains, including physical pain, sleep, concentration, negative feelings, social relationships, work capacity, and overall QOL, were identified after a yoga intervention. Results indicate preliminary evidence for yoga as a safe and effective QOL improvement method for women with primary dysmenorrhea. DISCUSSION Practitioners may consider yoga for management of primary dysmenorrhea. However, future research using larger RCTs of high methodological quality is needed to ascertain the magnitude of yoga's clinical significance.

Abstract
Objective To assess the gatekeeping effect and discharge safety in elderly referrals to the community nursing service (CNS) in a major accident & emergency department (AED). Methods Descriptive review analysis of the referrals in 2002–2004. Results Altogether 333 patients were accepted, comprising 5% of the total CNS referrals in the hospital: 323 were aged ≥65 (median age 81), 13.8% were living alone, 21.6% had unscheduled return to the AED within 14 days, and 11.7% in 15–28 days. The ≤14 days and 15–28 days admission to hospital was 15.0% and 6.0%, with 4.8% and 0.6% patients admitted with the same or related diagnosis as the first visit respectively, including missed fractures and stroke. One patient died 17 days after discharge. Eight of the 162 falls returned within 28 days with a second fall. Overall, 317 admissions were avoided with 1,978 bed-days saved. Living alone was strongly associated with unscheduled return and admission ≤14 and ≤28 days, while age was not. The six categories of community nursing care were fall-related, tube care, skin and soft tissue care, pain control, medical and diabetic care. Injections were given for cellulitis, pain, and diabetics. Forty-nine patients had phone follow-ups. Conclusion The gatekeeping effect of AED referrals to CNS remained small. The commonest referrals were falls with head injury. It was safe to discharge the elderly for CNS care. A wide range of home nursing care was feasible. CNS referral could decrease elderly return visits with falls. Living alone was strongly associated with return visit and admission.

Abstract
BACKGROUND Thrombocytosis is a hematologic abnormality in dogs that has been associated with various neoplastic, metabolic, and inflammatory conditions. OBJECTIVE To classify thrombocytosis in dogs based on severity and evaluate whether there are associations between severity and underlying disease processes. ANIMALS Seven hundred and fifteen dogs with thrombocytosis and 1,430 dogs with normal numbers of platelets. METHODS Retrospective study. Medical records of dogs with increased (>500 × 103 /μL; thrombocytosis group) and normal (300-500 × 103 /μL; control group) platelet counts between 2011 and 2015 were reviewed. Dogs were characterized by severity of platelet increase and diagnosis. Diagnostic categories included neoplasia, endocrine disease, inflammatory disease, or miscellaneous. RESULTS A total of 1,254 complete blood counts with thrombocytosis from 715 dogs were included in the study. Median platelet count in this population was 582 × 103 /μL (500-1,810 × 103 /μL). No correlation between severity of thrombocytosis and diagnosis was identified. Causes of secondary thrombocytosis included neoplasia (55.7%), endocrine disease (12.0%), and inflammatory disease (46.6%). Immune-mediated disease was common (22.2%), associated with frequent glucocorticoid administration, and had a significantly higher median platelet count (636 × 103 /μL [500-1,262 × 103 /μL] versus 565 × 103 /μL [500-1,810 × 103 /μL]) when compared to the other inflammatory processes (P < 0.001). The diagnoses in the thrombocytosis dogs differed significantly from the control population (P < 0.001). CONCLUSIONS AND CLINICAL IMPORTANCE Thrombocytosis is commonly associated with carcinoma and immune-mediated disease in dogs.

Abstract
Parkinson's disease is a neurodegenerative chronic condition with a declining trajectory and lack of a cure, making quality of life an important aspect of care. The purpose of this literature review was to analyze the state-of-the-science on the effects of non-pharmacological treatments on quality of life in person's with Parkinson's disease. Literature search was conducted using keywords in electronic databases up to September 1, 2016 and cross-searching the references of identified articles. Of the 259 articles generated, 26 met the eligibility criteria and were included in this review. The majority of studies (77%) were Level I evidence and 23% Level II evidence. The levels of study quality were: strong (50%), moderate (15%), and weak (35%). The interventions varied across studies with 15 studies evaluating a similar intervention. About 58% of the studies showed that the interventions improved quality of life. In conclusion, a variety of non-pharmacological interventions have been increasingly studied for their effects on quality of life in Parkinson's disease, showing initial promising results. However, most interventions were only examined by a limited number of studies and the minimal and optimal intervention doses needed for improving quality of life are yet unknown.

Abstract
BACKGROUND ADHD in childhood is associated with development of negative psychosocial and behavioural outcomes in adults. Yet, relatively little is known about which childhood and adulthood factors are predictive of these outcomes and could be targets for effective interventions. To date follow-up studies have largely used clinical samples from the United States with children ascertained at baseline using broad criteria for ADHD including all clinical subtypes or the use of DSM III criteria. AIMS To identify child and adult predictors of comorbid and psychosocial comorbid outcomes in ADHD in a UK sample of children with DSM-IV combined type ADHD. METHOD One hundred and eighteen adolescents and young adults diagnosed with DSM-IV combined type ADHD in childhood were followed for an average of 6years. Comorbid mental health problems, drug and alcohol use and police contact were compared for those with persistent ADHD, sub-threshold ADHD and population norms taken from the Adult Psychiatric Morbidity Study 2007. Predictors included ADHD symptomology and gender. RESULTS Persistent ADHD was associated with greater levels of anger, fatigue, sleep problems and anxiety compared to sub-threshold ADHD. Comorbid mental health problems were predicted by current symptoms of hyperactivity-impulsivity, but not by childhood ADHD severity. Both persistent and sub-threshold ADHD was associated with higher levels of drug use and police contact compared to population norms. CONCLUSIONS Young adults with a childhood diagnosis of ADHD showed increased rates of comorbid mental health problems, which were predicted by current levels of ADHD symptoms. This suggests the importance of the continuing treatment of ADHD throughout the transitional years and into adulthood. Drug use and police contact were more common in ADHD but were not predicted by ADHD severity in this sample.

Abstract
BACKGROUND/OBJECTIVE Osteoarthritis (OA) is a highly prevalent condition worldwide. Yoga is potentially a safe and feasible option for managing OA; however, the extent of long-term yoga adherence is unknown. The purpose of this study was to examine yoga adherence 6 months after participants completed an OA intervention program. METHODS This follow-up study employed a cross-sectional descriptive design using survey, interview, and video recordings to collect both quantitative and qualitative data. A total of 31 participants completed and returned the survey, and 10 videotaped their yoga practice for 1 week and participated in a face-to-face interview. RESULTS A majority of participants (n=19, 61%) reported that they were still practicing yoga 6 months after the intervention program. On average, participants reported practicing 21 to 30 minutes of yoga per day (32%) 3 to 4 days per week (47%). "Feeling good or feeling better after yoga practice" (50%) and "set aside a time" (31%) were the most common motivating factors for yoga adherence. Dealing with health problems (42%), having pain (25%), and being too busy (25%) were the major barriers. Qualitative data revealed that participants: (1) used mindful yoga movement, (2) incorporated other forms of exercise and resources during yoga practice, and (3) created personalized yoga programs. Additionally, the participants reported less OA pain, increased physical endurance, and more relaxation. CONCLUSION Many participants adhered to yoga practice 6 months post-intervention although not at the frequency and sequence as prescribed. Feeling better after practice motivated participants, but other factors remained key barriers.

Abstract
PURPOSE The study aims are to (a) describe nurse practitioners' (NPs') belief in effectiveness, knowledge, referral, and use of complementary/alternative therapies (C/ATs), (b) explore the initiation of C/AT dialogue between NPs and their patients, and (c) examine the relationships between demographic variables and NP C/AT knowledge, beliefs, use, referrals. DATA SOURCES A mixed-method cross-sectional online survey of licensed NPs (N = 2874) from a Midwestern state was analyzed using descriptive statistics, thematic analysis, and content analysis. CONCLUSIONS NPs (n = 410) report the most knowledge about prayer (40%) and mind-body practices (32%). Many NPs (84%) report using vitamins for personal use and 85% refer their patients for massage/bodywork. Most (95%) believe NPs should have knowledge of the most common C/AT and 81% believe C/AT have a legitimate use in allopathic medicine. NPs' knowledge, belief, use, and referral of C/AT are significantly correlated. NPs initiate C/AT dialogue with their patients 54% of the time. Factors that impact the NP and patient C/AT dialogue include patient/family openness, nature of the health problem, NP C/AT knowledge, time, and accessibility. IMPLICATIONS FOR PRACTICE Centralized C/AT sources could help expedite C/AT referrals. Implementing workplace C/AT clinics could help build knowledge, referral, personal use, and acceptance of C/AT.

Abstract
BACKGROUND Osteoarthritis (OA) is a common problem in older women that is associated with pain and disabilities. Although yoga is recommended as an exercise intervention to manage arthritis, there is limited evidence documenting its effectiveness, with little known about its long term benefits. This study's aims were to assess the feasibility and potential efficacy of a Hatha yoga exercise program in managing OA-related symptoms in older women with knee OA. METHODS Eligible participants (N=36; mean age 72 years) were randomly assigned to 8-week yoga program involving group and home-based sessions or wait-list control. The yoga intervention program was developed by a group of yoga experts (N=5). The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score that measures knee OA pain, stiffness, and function at 8 weeks. The secondary outcomes, physical function of the lower extremities, body mass index (BMI), quality of sleep (QOS), and quality of life (QOL), were measured using weight, height, the short physical performance battery (SPPB), the Pittsburgh Sleep Quality Index (PSQI), the Cantril Self-Anchoring Ladder, and the SF12v2 Health Survey. Data were collected at baseline, 4 weeks and 8 weeks, and 20 weeks. RESULTS The recruitment target was met, with study retention at 95%. Based on ANCOVAs, participants in the treatment group exhibited significantly greater improvement in WOMAC pain (adjusted means [SE]) (8.3 [.67], 5.8 [.67]; p=.01), stiffness (4.7 [.28], 3.4 [.28]; p=.002) and SPPB (repeated chair stands) (2.0 [.23], 2.8 [.23]; p=.03) at 8 weeks. Significant treatment and time effects were seen in WOMAC pain (7.0 [.46], 5.4 [.54]; p=.03), function (24.5 [1.8], 19.9 [1.6]; p=.01) and total scores (35.4 [2.3], 28.6 [2.1]; p=.01) from 4 to 20 weeks. Sleep disturbance was improved but the PSQI total score declined significantly at 20 weeks. Changes in BMI and QOL were not significant. No yoga related adverse events were observed. CONCLUSIONS A weekly yoga program with home practice is feasible, acceptable, and safe for older women with knee OA, and shows therapeutic benefits.

Abstract
A new integrated care pathway (ICP) proforma for gynaecological oncology patients was developed and introduced in early 2010. The ICP is a goal-defined and time-specified documentation by gynaecological oncology doctors and nurses, guided by certain parameters to be achieved in pre and postoperative days. All patients were admitted to the same unit and underwent a major abdominal/pelvic procedure for confirmed or suspected gynaecological malignancy, including hysterectomy and oophorectomy. The control group included 58 randomly selected patients from May 2008 to March 2009 and the intervention group comprised 52 patients, after the introduction of the ICP. The effectiveness was assessed with a variety of measurements: the duration of intraperitoneal drains, urethral catheters and intravenous fluids postoperatively; time taken for the patient to eat and drink; time taken to mobilisation; and the total length of stay in hospital. We also assessed whether the implementation of the care pathway was associated with an increase in adherence to prescribing guidelines for thromboprophylaxis and postoperative antibiotics and sodium docusate. The new ICP encouraged clearer documentation and regular review of fluids, drains and catheters. There was a modest reduction in the length of stay and an increase in prescribed thromboprophylaxis and sodium docusate ( Cheung et al. 2011 ).

Abstract
BACKGROUND Pelvic and acetabular fractures are complex injuries requiring specialist treatment. Our institution is the National Centre for Treatment and Management of these injuries. AIM To audit all referrals to our institution over a 6-month period and calculate the cost incurred by being the national referral centre. METHODS Retrospective review of database, and subsequent allocation of Casemix points to assess total cost of treatment for each patient referred to our institution. RESULTS 103 patients referred with pelvic or acetabular fracture for operative management. The furthest referral distance was 181miles. Over-all, the length of stay was 15.4 days. The average inclusive cost for a referral to our unit for operative management was €16,302. CONCLUSION Pelvic and acetabular fractures are complex injuries that require specialist referral unit management. However for these units to remain sustainable money needs to "follow the patient".
