Enhanced Hematopoietic Stem Cell Self-Renewal-Promoting Ability of Clonal Primary Mesenchymal Stromal/Stem cells Versus Their Osteogenic Progeny.

Long-term self-renewing hematopoietic stem cell (LT-HSC) homeostasis within the bone marrow (BM) of adult mammals is regulated by complex interactions between LT-HSC and a number of niche-associated cell types including mesenchymal stromal/stem cells (MSC), osteoblasts (OB), macrophage, and neuronal cells in close proximity with the vasculature. Here, we cloned and functionally characterized a murine BM MSC subpopulation that was uniformly Nestin+ Lepr + Sca-1+ CD146+ and could be stably propagated with high colony-forming unit fibroblast re-cloning efficiency. MSC synergized with SCF and IL-11 to support a 20-fold expansion in true LT-HSC after 10-days of in vitro coculture. Optimal stimulation of LT-HSC expansion was minimally dependent on Notch signaling but was significantly enhanced by global inhibition of Wnt signaling. The self-renewal-promoting activity of MSC was progressively lost when MSC clones were differentiated into mature OB. This suggests that the stage of osteoblast development may significantly impact the ability of osteolineage cells to support LT-HSC homeostasis in vivo. Stem Cells 2017;35:473-484.

Surgical Approach for Partial Nephrectomy in the Management of Small Renal Masses: A Systematic Review and Network Meta-Analysis.

Background: A variety of surgical and nonsurgical management options for small renal masses (SRMs) now exist. Surgery in the form of partial nephrectomy (PN) has three different approaches. It is unclear which PN approach, if any, offers superior clinical outcomes. Aim: The aim of this study is to compare outcomes in patients with SRMs <4 cm undergoing PN through the open partial nephrectomy (OPN), laparoscopic partial nephrectomy (LPN), or robotic partial nephrectomy (RPN) approach and to establish the advantages and disadvantages of the various approaches. Methods: A systematic literature search was conducted for studies comparing at least two of the above techniques. Eighteen studies and 17,013 patients were included in our study. A network meta-analysis with a frequentist framework was performed. OPN was used as the baseline comparator. The prespecified primary outcome was R0 resection rates. Secondary outcomes included operating time, ischemia time, blood loss, transfusion rates, urine leak rates, significant morbidity, length of stay, and recurrence. Results: There was no significant difference between the techniques in terms of R0 rates, tumor recurrence, urine leak rates, renal function, and >3a Clavien-Dindo complications. LPN had a longer ischemic time and operating time. OPN had a longer length of stay and higher average intraoperative blood loss. RPN had lower blood transfusion rates. Discussion: All approaches are acceptable from an oncological perspective. The minimally invasive approaches (i.e., RPN and LPN) offer advantages in terms of morbidity; however, LPN may increase ischemic time and operative duration. Variations between perioperative outcomes may influence the choice of approach on a case-by-case and institutional basis.

Direct Parent Engagement to Improve Fundamental Movement Skills in Children: A Systematic Review.

Fundamental movement skills (FMS) are basic movements in children that represent the building blocks for more complex motor skill development and act as a prerequisite for enduring sport and physical activity (PA) engagement and positive health-related behaviours. The FMS proficiency is currently inadequate worldwide, and consequently there are alarming levels of inactivity and childhood obesity. However, parents are role models to their children and possess the power to influence their PA behaviour. This review investigated if parent-focused interventions could improve FMS in 2-7-year-old children and evaluated which setting and method of parent engagement was most impactful. Keyword searches were conducted via Scopus, Web of Science, SPORTDiscus, PubMed, Science Direct, and Google Scholar. Only nine articles met the inclusion criteria. No research originated from the United Kingdom, highlighting the urgent need for further FMS interventions involving parents. The FMS improved in all nine studies, with significant changes in seven of the articles (p < 0.05). Parent-child co-activity, the education and empowerment of parents, and the provision of clear FMS guidance, messaging, and structure can positively influence children's FMS. Recently, smartphone apps have increased the feasibility and accessibility of FMS practice at home and may be integral to future interventions. Further research with direct parental involvement is clearly warranted.

Reasons for admission to service and overrepresentation of Black youth in the child welfare system in Ontario, Canada: Does race matter?

BACKGROUND: In studies exploring racial disparities in the Canadian child welfare systems, evidence is still lacking on the reasons for admission of children to service. OBJECTIVE: This study investigates the reasons for admission to service in Ontario child welfare based on racial identities. METHODS: We analyzed three-time points (2018, 2019, and 2020) of the Ontario Looking After Children (OnLAC) project. The sample included 4036 children (Mage = 14.30, SD = 2.21; 39.22 % girls). Univariate and multiple random-effects (REs) logistic regressions were performed to analyze the admission to service according to racial identities. RESULTS: The results showed that the most frequent reason for admission to service was caregiver capacity in 2018 (56.02 %), 2019 (57.76 %), and 2020 (55.49 %). The results revealed few differences between racial groups on the reasons for their admission to service. There were more differences between racial groups in 2019 and 2020. The three-year cohort analyses showed that Black youth were less likely to have admission to service due to harm by omission (AOR = 0.41, 95%CI 0.18-0.93, z = -2.14, p < .05) and emotional harm (AOR = 0.40, 95%CI 0.17-0.92, z = -2.12, p < .05) than other racial groups. Results from the multiple random-effects logistic regression showed that in 2019 (AOR = 1.83, 95%CI 1.28-2.62, z = 3.32, p < .01) and 2020 (AOR = 2.13, 95%CI 1.41-3.21, z = 3.58, p < .01), youth were particularly at risk of having been admitted to service for caregiver capacity. CONCLUSIONS: The present study reveals a comprehensive description of the reasons for admission in child welfare in Ontario according to racial identities. Implications for research, prevention, and intervention are discussed.

The early Cambrian Kylinxia zhangi and evolution of the arthropod head.

The early Cambrian Kylinxia zhangi occupies a pivotal position in arthropod evolution, branching from the euarthropod stem lineage between radiodonts (Anomalocaris and relatives) and "great-appendage" arthropods.1,2 Its combination of appendage and exoskeletal features is viewed as uniquely bridging the morphologies of so-called "lower" and "upper" stem-group euarthropods.3,4 Microtomographic study of new specimens of Kylinxia refines and corrects previous interpretation of head structures in this species. Phylogenetic analyses incorporating new data reinforce the placement of Kylinxia in the euarthropod stem group but support new hypotheses of head evolution. The head of Kylinxia is composed of six segments, as in extant mandibulates, e.g., insects.5 In Kylinxia, these are an anterior sclerite associated with an unpaired median eye and paired lateral eyes (thus three rather than five eyes as was previously described1), deutocerebral frontal-most appendages, and four pairs of biramous appendages (rather than two pairs of uniramous appendages). Phylogenetic trees suggest that a six-segmented head in the euarthropod crown group was already acquired by a common ancestor with Kylinxia. The segmental alignment and homology of spinose frontal-most appendages between radiodonts and upper stem-group euarthropods6,7,8,9,10 is bolstered by morphological similarities and inferred phylogenetic continuity between Kylinxia and other stem-group euarthropods.

The changing pattern of antimicrobial resistance within 42,033 Escherichia coli isolates from nosocomial, community and urology patient-specific urinary tract infections, Dublin, 1999-2009.

OBJECTIVE: To investigate the changing pattern of antimicrobial resistance in Escherichia coli urinary tract infection over an eleven year period, and to determine whether E. coli antibiotic resistance rates vary depending on whether the UTI represents a nosocomial, community acquired or urology patient specific infection. PATIENT AND METHODS: A retrospective analysis of the 42,033 E. coli urine isolates from the 11-year period 1999-2009 in a single Dublin teaching hospital was performed. WHONET(TM) software was used to analyse the changing pattern of sensitivity and resistance of E. coli to commonly used antibiotics over the study period. The origins of the urine samples were stratified into three groups: inpatients with nosocomial UTIs; urine originating from the emergency department and general practice (community UTIs); and UTIs in urology patients. RESULTS: Urinary tract infections in the urology patient population demonstrate higher antibiotic resistance rates than nosocomial or community UTIs. There were significant trends of increasing resistance over the 11-year period for ampicillin, trimethoprim, gentamicin and ciprofloxacin, and significant differences in co-amoxyclav, gentamicin, nitrofurantion and ciprofloxacin resistance rates depending on the sample origin. Ampicillin and trimethoprim were the least active agents against E. coli, with total 11-year resistance rates of 58.3 and 33.8%, respectively. The overall gentamicin resistance rate was 3.4% and is climbing at a rate of 0.7% per year (P < 0.001). Within the urology patient population the resistance rate was 6.4%. Ciprofloxacin resistance approaches 20% in the nosocomial UTI population and approaches 30% in the urology population; however, it remains a reasonable empirical antibiotic choice in this community, with an 11-year resistance rate of 10.6%. CONCLUSIONS: E. coli remains the commonest infecting uropathogen in the community and hospital setting with its incidence climbing from 50 to 60% of UTIs over the 11-year period. Neither penicillins nor trimethoprim represent suitable empirical antimicrobials for UTI and ciprofloxacin resistance in this Dublin-based study renders it unsuitable empirical therapy for nosocomial UTIs and UTIs in the urology population. The dramatic 11-year rate increase in gentamicin resistance is of paramount concern.

Prospective study of antibiotic prophylaxis for prostate biopsy involving >1100 men.

We aimed to compare infection rates for two 3-day antibiotic prophylaxis regimens for transrectal ultrasound-guided prostate biopsy (TRUSgbp) and demonstrate local microbiological trends. In 2008, 558 men and, in 2009, 625 men had TRUSgpb. Regimen 1 (2008) comprised 400 mg Ofloxacin immediately before biopsy and 200 mg 12-hourly for 3 days. Regimen 2 (2009) comprised Ofloxacin 200 mg 12-hourly for 3 days commencing 24 hours before biopsy. 20/558 (3.6%) men had febrile episodes with regimen 1 and 10/625 (1.6%) men with regimen 2 (P = 0.03). E. coli was the most frequently isolated organism. Overall, 7/13 (54%) of positive urine cultures were quinolone resistant and (5/13) 40% were multidrug resistant. Overall, 5/9 (56%) patients with septicaemia were quinolone resistant. All patients were sensitive to Meropenem. There was 1 (0.2%) death with regimen 1. Commencing Ofloxacin 24 hours before TRUSgpb reduced the incidence of febrile episodes significantly. We observed the emergence of quinolone and multidrug-resistant E. coli. Meropenem should be considered for unresolving sepsis.

Urological service provision during the COVID-19 period: the experience from an Irish tertiary centre.

PURPOSE: Urological service provision has changed dramatically with the advent of the SARS-CoV-2, necessitating restructuring and reorganization. The aim of this study was to review the reorganization of our unit, map the change in volume of departmental activities and discuss potential solutions. METHODS: Departmental activities over the months of April and May 2020 and 2019 were analysed. Details of admissions, operations, diagnostic procedures, outpatient reviews, morbidities and mortalities were recorded. Operations were performed on two sites, with elective operation transferred to an offsite, COVID-free hospital. RESULTS: Seventy-four emergency operations were performed onsite, with 85 elective operations outsourced. A total of 159 operations were performed, compared with 280 in the same period in 2019. Five (5.0%) of 101 admitted patients to the COVID hospital contracted COVID-19. No patients outsourced to the COVID-free hospital were infected there. Outpatient referrals to urology service decreased from 928 to 481. There was a 66% decrease in new cancer diagnoses. A virtual review clinic was established, with remaining outpatients reviewed through a telephone clinic platform. CONCLUSION: Compared with 2019, we performed fewer operations and outpatient procedures, had fewer admissions and diagnosed fewer patients with new cancers. However, outsourcing elective operation to designated non-COVID hospitals prevented the infection of any patient with COVID-19 in the post-operative period. The use of virtual clinic and telephone clinic has had some success in replacing traditional outpatient visits. The overall significant decrease in operative volume will likely precipitate a mismatch between demand and service provision in the coming months, unless capacity is increased.

Implementation of a nurse-led lower urinary tract symptoms (LUTS) clinic reduces general urology clinic workload in a Model 4 Hospital: a pilot study in Tallaght University Hospital.

BACKGROUND: With among the lowest urologist per population ratios in Europe, the demand for urology specialist review in Ireland far exceeds supply. Lower urinary tract symptoms (LUTS) account for a significant number of referrals. The traditional paradigm of every patient being reviewed in a consultant-led clinic is unsustainable. New models of care with nurse-led clinics represent an opportunity to optimise limited resources. METHODS: Existing long-waiting male LUTS referrals were triaged to a specialist nurse-led LUTS clinic. After urology CNS assessment, charts were reviewed by a consultant urologist and a plan formulated. Relevant data were prospectively collected and analysed. RESULTS: Fifty-eight new male patients with LUTS were seen over a 6-month period with an average waiting time of 15.8 months. Patients were assessed with uroflowmetry, IPSS and DRE. Mean age was 64, IPSS 14.5, Qmax 18.3 ml/s and PVR 89 ml. Thirty patients (52%) were discharged directly with lifestyle modification and medical therapy. Twenty-eight patients (48%) required one or more further investigations and subsequent review; 11 had flexible cystoscopy, 4 had urodynamics, 5 had prostate MRI, and 2 patients were listed for surgery (TURP and circumcision). The remaining 10 patients were for review post trial of lifestyle modifications and/or medical treatment. After review/investigations, 4 more patients were discharged. A total of 32 patients (55%) were discharged or listed for surgery after initial assessment. This total increased to 62% after a second review/investigations. CONCLUSION: Introduction of a CNS-led LUTS clinic has significantly reduced the number of patients requiring follow-up in general urology clinics, representing a quality improvement in service provision.

The utility of stent on strings in clinical practice.

INTRODUCTION: Various types of ureteric stents are used in the management of ureteric stones. Stents on strings (SOS) are an attractive option as they may be removed without the need for instrumentation. There is some hesitation using SOS due to perceived complications and the risk of premature dislodgement. The aim of this study was to evaluate the utility of SOS compared with the conventional stent (CS). METHODS: A retrospective review was performed on all ureteric stents removed in the urology department over a 7-month period. Only stents inserted during the endoscopic management of ureteric stones were included in analysis. Patients were contacted to identify the incidence of those seeking medical attention while the stent was in situ or within 2 weeks of stent removal. A basic cost analysis was performed. RESULTS: One hundred and sixty cases were identified (98 CS, 62 SOS). No SOS was dislodged prematurely. One SOS was removed cystoscopically due to a broken string. There was no significant difference in the number of patients with SOS seeking medical attention following stent placement compared with those with CS (38.1% (12/51) vs 25.6% (22/86), p = 0.48). There was an estimated cost saving of €23,790 associated with the use of SOS during the study period (€390/case). The use of SOS created additional capacity which was utilised for diagnostic cystoscopy. CONCLUSION: The SOS appeared to be well tolerated and showed similar complication rates as the CS. The use of SOS resulted in a significant cost saving and increased the availability of cystoscopy for other indications.

Implications of faecal ESBL carriers undergoing TRUS-guided prostate biopsy (TRUSPB): role of screening prior to TRUSPB.

INTRODUCTION: Modification of antibiotic prophylaxis prior to transrectal ultrasound-guided prostate biopsy (TRUSPB) based on pre-procedure rectal culture results is effective for prevention of infection from fluoroquinolone (FQ)-resistant and extended-spectrum beta-lactamase (ESBL) Escherichia coli strains. This has several implications for service delivery and cost. Our aim was to audit sepsis rates after introduction of ESBL screening and to identify risk factors for FQ resistance in ESBL strains and factors for sepsis risk. METHODS: This was a prospective cohort study from 2013 to 2016. TRUSPB patients underwent pre-procedure rectal swabs. ESBL-positive patients received amikacin in addition to ciprofloxacin prophylaxis. Patients filled a formal risk assessment questionnaire prior to biopsy. RESULTS: Sepsis rate after introduction of targeted prophylaxis reduced from 3.1% (2009-2012) to 1.4% (2013-2016). Of 38 ESBL patients, n = 5 (13%) developed severe post-TRUSPB sepsis. Among the FQ-resistant ESBL producers, the sepsis rate was 24%. Predictive factor for FQ resistance in ESBL producers included-antibiotic use in the last 3 months (OR 15). The logistic regression analysis did not identify any significant factor for post-TRUSPB sepsis in ESBL-positive patients once they had received additional prophylaxis. CONCLUSION: In the face of rising TRUSPB sepsis and higher sepsis rates with ESBL carriers despite additional prophylaxis, introduction of a targeted antibiotic prophylaxis prior to TRUSPB sepsis prostate biopsies based on rectal swabs or urine cultures may reduce sepsis rates or clinicians may find themselves leaning towards increasingly performing transperineal biopsies with lower sepsis rates supporting the 'trexit' initiative.

Urinary catheters in the emergency department: a prospective audit to improve quality control.

INTRODUCTION: The best way to prevent urinary catheter related complications is to avoid unnecessary insertions of catheters and removing the catheters when they are no longer necessary. Previous studies have shown 47% documentation rate of urinary catheter (UC) insertion in the Emergency Department (ED) and have found one-sixth of patients in the ED have no indication for UC insertion. The aim of this audit was to record the indications and documentation of UC insertion in the ED and to propose an intervention to improve the quality of these processes. MATERIAL AND METHODS: A prospective audit was conducted in a tertiary university teaching hospital in Ireland over an eight-week period. A week-long intervention was conducted in the ED to educate staff, an ED doctor was involved in directly communicating this to the staff thereafter and concise labels were introduced to document relevant details about each UC insertion. The pre-intervention and post-intervention data was compared using Chi-Square tests. RESULTS: A total of 103 (50 pre-intervention and 53 post-intervention) consecutive age and gender matched patients were recruited in the audit over 8 weeks. The documentation for UC insertion improved by 22% (8% to 30%, (p <0.001, chi-square) while the non-indication for UC insertion reduced by 6% (36% to 30%, p = 0.53, chi-square). CONCLUSIONS: A simple intervention achieved significantly improved documentation of UC insertion and a trend toward increased appropriateness of UC insertion. This audit serves as an example to improve quality control around UC insertion which could be adopted in other institutions.

Neglect, educational success, and young people in out-of-home care: Cross-sectional and longitudinal analyses.

Maltreated young persons in out-of-home care often have poor educational outcomes, heightening their risk of long-term psychosocial disadvantage (Forsman, Brännström, Vinnerljung, & Hjern, 2016). In their systematic reviews, Romano, Babchishin, Marquis, and Fréchette (2014) and O'Higgins, Sebba, and Gardner (in press) found evidence that neglect was more often linked with low academic achievement, whereas abuse was more likely to be associated with behavioral difficulties. In large samples of young persons in out-of-home care in Ontario, Canada, who had experienced mainly neglect, we investigated risk and protective factors as predictors of educational success. In a cross-sectional hierarchical regression analysis (N=3659, aged 11-17 years), female gender, youth educational aspirations, caregiver educational aspirations for youth, time with current caregiver, internal developmental assets, and positive mental health were associated with better educational success. Neglect, grade retention, special educational needs, ethnic minority status, behavioral problems, and soft-drug use were associated with poorer educational outcomes. Gender significantly moderated caregiver educational aspirations and youth placement type. In a longitudinal analysis of a subsample (N=962, aged 11-15 years at Time 1), covering three years, a large decline in educational success (d=-0.80) was observed. Female gender, internal developmental assets, and positive mental health positively predicted, and soft drug use negatively predicted, greater educational success at Time 2. These results point to factors that help or hinder educational success among young people in care and should inform new interventions or improved versions of existing ones that address educational success in the context of neglect.

Incidence of Visible Hematuria Among Antithrombotic Agents: A Systematic Review of Over 175,000 Patients.

OBJECTIVE: To determine the probability of visible hematuria with antithrombotic agents and to evaluate association of urologic etiology in antithrombotic-related hematuria. METHODS: Preferred Reporting Items in Systematic Reviews and Meta-Analyses guidelines were followed to conduct a systematic review using search engines PUBMED and SCOPUS with the terms "(hematuria) OR (haematuria) OR urinary bleeding)) AND ((anticoagulants) OR anticoagulation) OR noac) OR novel anticoagulants) OR antiplatelet) OR dabigatran) OR rivaroxaban) OR apixaban) OR warfarin) OR aspirin) OR heparin) OR dipyridamole)." Raw data were used to perform a pooled analysis. Chi-square and logistic regression analysis were used for statistical analyses. RESULTS: Twenty-two studies describing 175,114 patients met inclusion criteria. Odds ratio of hematuria with warfarin to rivoraxaban was 33 and warfarin to dabigatran was 16. The odds ratio of hematuria for oral anticoagulant (26.7%) to prophylactic parenteral anticoagulant (1.1%) agents was 9.6. Antiplatelet agents are 76 times less likely to cause hematuria compared to anticoagulants. Odds of hematuria with aspirin were 6.7 times the odds with clopidogrel and 3.5 times the odds with ticagrelor. Dabigatran was 198 times more likely to cause major hematuria compared to warfarin, whereas clopidogrel is 1.2 times more likely to cause major hematuria compared to aspirin. Urologic pathology was identified in 44% (234/532) of cases, malignancy in 24%. CONCLUSION: Warfarin use poses the greatest risk for hematuria but is unlikely to cause major hematuria, whereas novel antithrombotic agents are more commonly associated with major hematuria. This review further characterizes the risk profile of antithrombotic agents and associated hematuria to equip clinicians with knowledge to choose an appropriate antithrombotic agent in patients with high-risk hematuria.

Quantitative Analysis of Technological Innovation in Urology.

OBJECTIVE: To assess major areas of technological innovation in urology in the last 20 years using patent and publication data. METHODS: Patent and MEDLINE databases were searched between 1980 and 2012 electronically using the terms urology OR urological OR urologist AND "surgeon" OR "surgical" OR "surgery". The patent codes obtained were grouped in technology clusters, further analyzed with individual searches, and growth curves were plotted. Growth rates and patterns were analyzed, and patents were correlated with publications as a measure of scientific support and of clinical adoption. RESULTS: The initial search revealed 417 patents and 20,314 publications. The top 5 technology clusters in descending order were surgical instruments including urinary catheters, minimally invasive surgery (MIS), lasers, robotic surgery, and image guidance. MIS and robotic surgery were the most emergent clusters in the last 5 years. Publication and patent growth rates were closely correlated (Pearson coefficient 0.78, P <.01), but publication growth rate remained constantly higher than patent growth, suggesting validated scientific support for urologic innovation and adoption into clinical practice. CONCLUSION: Patent metrics identify emergent technological innovations and such trends are valuable to understand progress in the field of urology. New surgical technologies like robotic surgery and MIS showed exponential growth in the last decade with good scientific vigilance.

A prospective audit on the effect of training and educational workshops on the incidence of urethral catheterization injuries.

INTRODUCTION: The incidence of iatrogenic urethral catheterization (UC) injuries is approximately 0.3%. Resultant complications are associated with patient morbidity and unnecessary healthcare costs. Our aim was to investigate whether educational training workshops decreased the incidence of UC-related injuries. METHODS: A prospective audit was performed to calculate incidence, morbidity, and costs associated with iatrogenic UC injury from January to July 2015. Educational workshops were then conducted with healthcare staff and training modules for junior doctors. UC-related incidence, morbidity, and costs in the subsequent six-month period were recorded prospectively and compared with the previous data. RESULTS: The incidence of iatrogenic UC injuries was reduced from 4.3/1000 catheters inserted to 3.8/1000 catheters after the intervention (p=0.59). Morbidity from UC increased in the second half in the form of increase in cumulative additional inpatient hospital stay (22 to 79 days; p=0.25), incidence of urosepsis (n=2 to n=4), and need for operative intervention (n=1 to n=2). The cost of managing UC injuries almost doubled in the period after the training intervention (€50 449 to €90 100). CONCLUSIONS: Current forms of educational and training interventions for UC did not significantly change morbidity or cost of iatrogenic UC injuries despite a decrease in incidence. Improved and intensive training protocols are necessary for UC to prevent avoidable iatrogenic complications, as well as a safer urethral catheter design.

Identifying the core competencies of community support providers working with people with psychiatric disabilities.

The study was intended to identify core competencies for community support providers working with people with psychiatric disabilities. Using multiple methods developed from previous research in the field of developmental disabilities, 18 consumers receiving services and 16 staff members from two mental health community support programs identified a list of 68 competencies that included personal attributes, knowledge, and skills. Based on a card sort task, 34 consumers receiving services and 34 support workers from six mental health community support programs rated 59 of the 68 competencies as being either absolutely necessary or desirable. Results of a second card sort task found that a majority of competencies identified as being needed pre-employment were personal attributes consistent with adopting a person-centered approach. Competencies categorized as to be learned on the job involved special knowledge and skills specific to working with people with psychiatric disabilities. The range of personal attributes, knowledge, skills represented in the identified competencies reflects the complexity of contemporary mental health community support. Findings are indicative of the need for specialized training and supervision that has not been typically available in the community mental health sector.

Profiles and predictors of behavioral resilience among children in child welfare.

Children living in out-of-home care have experienced a multitude of adversities, often resulting in compromised functioning. The current study used Ontario Looking After Children (OnLAC) project data to estimate developmental trajectories of behavioral outcomes (i.e., conduct and emotional problems) over a 4-year period (i.e., ages 6-10 to 9-13) in 313 children living in out-of-home care. Predictors measured at baseline (e.g., sex) and across the subsequent 4-year period (e.g., parenting practices) were also investigated. Findings indicated that 64.2% and 58.6% followed resilient trajectories for conduct behaviors and emotional functioning, respectively. Predictors of resilient trajectories included internal developmental assets, number of children in the home, whether the child was receiving treatment, and positive parenting. Findings need to be interpreted with an understanding that children in out-of-home care have varying levels of functioning across various domains (e.g., educational, social) other than the ones measured here. Predictors were static and dynamic and cut across various contexts, emphasizing the importance of considering child functioning within an ecological model.

Multilevel correlates of behavioral resilience among children in child welfare.

Resilience, defined as positive adaptation and functioning following exposure to significant adversity, is an important topic of investigation in child welfare. The current study used data from the Ontario Looking After Children (OnLAC) project to estimate the prevalence of behavioral resilience (i.e., lower frequency of conduct and emotional problems, higher frequency of prosocial behavior) in 531 5-9 year olds living in out-of-home care, and to determine how behaviorally-resilient children are functioning in other domains (i.e., peer relationships and academic performance). Furthermore, hierarchical linear modeling was used to examine the contribution of four levels of analysis (i.e., child, family, child welfare worker, and child welfare agency) on behaviors and to identify the contribution of predictor variables within each of these levels. Findings indicated that 50-70% of children exhibited resilience on one behavioral outcome while approximately 30% showed resilience on at least two of the outcomes. Also, 8.4-9.6% exhibited resilience on one of the behavioral outcomes in addition to peer relationships and academic performance. The child level accounted for the highest proportion of total explained variance in behavioral outcomes, followed by the family-, child welfare worker-, and child welfare agency-levels. A number of child and foster family variables predicted behavioral functioning. Findings indicate that it is important to inquire about children's functioning across multiple domains to obtain a comprehensive developmental assessment. Also, child and foster family characteristics appear to play considerable roles in the promotion of behavioral resilience.
