Family structure and children's risk of child protective services re-reports.

BACKGROUND: Single parent families are at higher risk of re-report to Child Protective Services (CPS) than two-parent families. Yet, how single-family homes differ in risk from two-parent families remains under researched. OBJECTIVE: To identify heterogenous patterns of child and caregiver factors among CPS-involved families and the subsequent risk for CPS re-report based on child and family characteristics (i.e., sociodemographic information, family structure, and risk indicators). PARTICIPANTS AND SETTING: Data were from the 2017 National Child Abuse and Neglect Data System Child File (N = 249,026). METHODS: We conducted latent class analysis (LCA) to identify discrete patterns (i.e., classes) based on child and caregiver risk indicators (e.g., substance use, behavioral health). We then used logistic regression to examine family structure and other family characteristics and CPS indicators predicted CPS re-report for each class. RESULTS: Results yielded five distinct classes: 1) Financial Stressors (25 % of the sample); 2) Caregiver Substance Use (16 %); 3) Complex Household Stressors (3 %); 4) Child Disabilities (4 %); and 5) Minimal Household Stressors (53 %). Family structure was significantly associated with CPS re-reports for Classes 1, 2, and 5. For Class 1, single father families had increased odds of CPS re-report compared to other family structures. For Classes 2 and 5, single father families' odds of CPS re-reports were greater than those of married families, but lower than single mother families. CONCLUSIONS: Children growing up in single father families have different likelihoods of repeat CPS involvement compared to those in single mother and married families. Financial stressors and parental substance use within single father families should be addressed.

Model matters: Differential outcomes in traumatic optic neuropathy pathophysiology between blunt and blast-wave mediated head injuries.

Over 3 million people in the United States live with long-term disability because of a traumatic brain injury (TBI). The purpose of this study was to characterize and compare two different animal models of TBI (blunt head trauma and blast TBI) to determine common and divergent characteristics of these models. With recent literature reviews noting the prevalence of visual system injury in animal models of TBI, coupled with clinical estimates of 50-75% of all TBI cases, we decided to assess commonalities, if they existed, through visual system injury. A unilateral (left directed) blast and repeat blast model injury with coup-contra-coup injury patterns were compared to a midline blunt injury. Injuries were induced in adult male mice to observe and quantify visual deficits. Retinal ganglion cell loss and axonal degeneration in the optic tract, superior colliculus, and lateral geniculate nuclei were examined to trace injury outcomes throughout major vision-associated areas. Optokinetic response, immunohistochemistry, and western blots were analyzed. Where a single blunt injury produces significant visual deficits a single blast injury appears to have less severe visual consequences. Visual deficits after repeat blasts are similar to a single blast. Single blast injury induces contralateral damage to the right optic chiasm and tract whereas bilateral injury follows a single blunt TBI. Repeat blast injuries are required to see degeneration patterns in downstream regions similar to the damage seen in a single blunt injury. This finding is further supported by amyloid precursor protein (APP) staining in injured cohorts. Blunt injured groups present with staining 1.2 mm ahead of the optic nerve, indicating axonal breakage closer to the optic chiasm. In blast groups, APP was identifiable in a bilateral pattern only in the geniculate nucleus. Evidence for unilateral neuronal degeneration in brain tissue with bilateral axonal ruptures are pivotal discoveries in this model differentiation. Analysis of the two injury models suggests that there is a significant difference in the histological outcomes dependent on injury type, though visual system injury is likely present in more cases than are currently diagnosed clinically.

Concern for Increased Prevalence of Heyde's Syndrome in Patients on Hemodialysis.

The association between aortic stenosis and increased gastrointestinal arteriovenous malformations is known as Heyde's syndrome. An acquired von Willebrand deficiency mediates the connection between these two seemingly dispersed pathologies. As von Willebrand factor passes through a stenosed aorta, it is broken down and can no longer inhibit angiogenesis, leading to angiodysplasias. Heyde's syndrome can manifest with chronic, refractory anemia requiring multiple hospitalizations for symptomatic gastrointestinal bleeding and transfusion. Hitherto, Heyde's syndrome has been considered exceptionally rare, with 1-3% of populations with aortic stenosis. However, given that 31.7% of patients with gastrointestinal angioplasty have aortic stenosis and gastrointestinal arteriovenous malformations are not screened for in patients without anemia, the prevalence of Heyde's syndrome is most likely higher than currently reflected in the literature. Also, the prevalence of Heyde's syndrome in populations who are predisposed to angiodysplasias, such as those on hemodialysis, is understudied. We aim to impart a need for increased research on the prevalence of Heyde's syndrome, especially in high-risk patients. This case report presents a patient with severe Heyde's syndrome on hemodialysis, showing an unconsidered risk factor for Heyde's syndrome in need of further research.

Women in Irish urology: An examination of female representation amongst attendees of the Irish Society of Urology annual meeting (2008-2020).

BACKGROUND: There is underrepresentation of women at surgical conferences. We examine the representation of women in Irish urology by looking at gender balance within the Irish Society of Urology (ISU) conference. AIMS: ISU programmes over thirteen years from 2008 to 2020 were assessed and female representation in session chairs, guest speakers, poster and oral presentations identified. Gender distributions of authors for each year was examined. To investigate changes in female representation temporally, the period of this study (2008-2020) was subdivided and compared: 2008-2013 and 2014-2020. RESULTS: 76 sessions were presided over by 138 chairs, of which 6 (4.3%) were female. Eight conferences had zero female chairs. 62 guest lectures were given, 6 (9.6%) by women. Of total 340 poster and 434 oral presentations, women delivered 24.9% (0-47.5%) of posters and 31.6% (10.3-59.4%) of oral presentations. We found no significant difference in the percentage of female poster presentations between the time periods 2008-2013 (m = 18.2, sd = 13.7) and 2014-2020 (m = 34.3, sd = 17.8), t(11) = -1.4, p > 0.05. However, we found a significant difference in the percentage of female oral presentations between the periods 2008-2013 (m = 18.7, sd = 14.2) and 2014-2020 (m = 40.6, sd = 14.5), t(11) = -2.8, p < 0.05. CONCLUSIONS: Our study is the second to examine female representation in Irish urology. Session chairs and guest speakers were grossly overrepresented by males as were oral and poster presentations. Despite lacking female influence overall, in more recent years there was an increased representation of women. Societies should strive to increase female representation, as this perpetuates a positive feedback loop, encouraging future female trainees to pursue urological surgery.

Does instillation of lidocaine gel following flexible cystoscopy decrease the severity of post procedure symptoms? A randomised controlled trial assessing the efficacy of lidocaine gel post flexible cystoscopy.

OBJECTIVE: To assess whether instillation of lidocaine gel both before and after flexible cystoscopy is more effective at reducing post procedural symptoms than instillation of lidocaine gel pre flexible cystoscopy alone. We hypothesise that inadequate urethral dwell time and dilution of lidocaine gel by the irrigation fluid during flexible cystoscopy limits its anaesthetic efficacy. Only one other study has attempted to reduce bothersome urinary symptoms through an intervention after flexible cystoscopy. METHODS: This was a randomised controlled trial in which patients were randomised 1:1 to receive lidocaine gel pre and post flexible cystoscopy (treatment) or lidocaine gel pre flexible cystoscopy only (control). Patient-reported outcome measures were used to assess symptoms and quality of life prior to cystoscopy, on day 2 and day 7 post cystoscopy. RESULT: Fifty patients were divided equally between the treatment and control groups. There were no significant differences in baseline characteristics between the groups (p = 1.000). An overall symptoms variable was measured, though no significant difference was found in the distribution of responses between the groups at baseline, 2 or 7 days after the flexible cystoscopy (p = 0.423, 0.651,0.735). In the treatment group, 1 patient (4.0%) presented to a doctor for review following flexible cystoscopy, and 4 patients (16.0%) presented in the control group (p = 0.349). CONCLUSION: Initial study results suggest that post-operative lidocaine does not significantly limit the exacerbation of urinary symptoms following flexible cystoscopy; however, our results are not powered to detect a small difference. We do not recommend a change in practice based on our results.

The Canadian Neuromuscular Disease Registry 2010-2019: A Decade of Facilitating Clinical Research Througha Nationwide, Pan-NeuromuscularDisease Registry.

We report the recruitment activities and outcomes of a multi-disease neuromuscular patient registry in Canada. The Canadian Neuromuscular Disease Registry (CNDR) registers individuals across Canada with a confirmed diagnosis of a neuromuscular disease. Diagnosis and contact information are collected across all diseases and detailed prospective data is collected for 5 specific diseases: Amyotrophic Lateral Sclerosis (ALS), Duchenne Muscular Dystrophy (DMD), Myotonic Dystrophy (DM), Limb Girdle Muscular Dystrophy (LGMD), and Spinal Muscular Atrophy (SMA). Since 2010, the CNDR has registered 4306 patients (1154 pediatric and 3148 adult) with 91 different neuromuscular diagnoses and has facilitated 125 projects (73 academic, 3 not-for-profit, 3 government, and 46 commercial) using registry data. In conclusion, the CNDR is an effective and productive pan-neuromuscular registry that has successfully facilitated a substantial number of studies over the past 10 years.

People with severe problematic personality traits and offending histories: What influences occupational participation?

BACKGROUND: Occupational participation is important for personality disordered offenders (PDOs) because it is integral to health and desistance from offending. What influences occupational participation is unknown for PDOs in the community, limiting effective intervention to affect change. In England and Wales, the Offender Personality Disorder Pathway aims to improve outcomes for people considered highly likely to have a severe personality disorder and who present a high risk of reoffending, who are determined to be PDOs on the basis of a structured assessment. This study identified the influencers of occupational participation for the population who receive this service. METHOD: In this critical realist, qualitative study, narrative interviews were conducted with 18 PDOs supervised by probation in England. Transcripts were analyzed using a grounded theory approach to establish influencers of occupational participation. RESULTS: Four themes describe influencers of occupational participation: function of occupations; influence of the past; external forces; and learning and adaptation. The latter theme reflected understandings of occupational adaptation described by the Model of Human Occupation. CONCLUSIONS: An intervention to increase prosocial occupational participation should be developed and evaluated for PDOs in the community, taking account of occupational participation over the life course.

The Management of Incidental Prostate Cancer Following TURP

Aims The aim of this study was to assess the incidence, management and outcomes of incidentally diagnosed prostate cancer following TURP. Methods A retrospective review was performed using the histopathological departments' database of all patients who underwent a TURP across two university teaching hospitals over a ten year period. Results During the study period, a total of 826 patients underwent a TURP. 72 (10.3%) had an incidental diagnosis of CaP following TURP. 46 (63.9%) were managed expectantly while 26 (36.1%) underwent active treatment. Overall mortality was 29.2% (n=21) while cancer specific mortality was 6.9% (n=5). All these patients were in the hormonal treatment sub-group. Conclusion Our study demonstrates an expectant approach is favourable in low risk disease. Curative treatment does need to be considered for younger patients with a long life expectancy or patients with higher risk disease.

Optimising the biocompatibility of 3D printed photopolymer constructs in vitro and in vivo.

3D printing is a rapid and accessible fabrication technology that engenders creative custom design solutions for cell scaffolds, perfusion systems and cell culture systems for tissue engineering. Critical to its success is the biocompatibility of the materials used, which should allow long-term tissue culture without affecting cell viability or inducing an inflammatory response for in vitro and in vivo applications. Polyjet 3D printers offer arguably the highest resolution with the fewest design constraints of any commercially available 3D printing systems. Although widely used for rapid-prototyping of medical devices and 3D anatomical modelling, polyjet printing has not been adopted by the tissue engineering field, largely due to the cytotoxicity of leachates from the printed parts. Biocompatibility in the context of cell culture is not commonly addressed for polyjet materials, as they tend to be optimised for their ability to fabricate complex structures. In order to study the potential issues surrounding the leaching of toxins, we prepared cell culture substrates using the commercially available MED610 photopolymer. The substrates were cleaned using either the manufacturer-specified 'biocompatible' washing procedures, or a novel protocol incorporating a sonication in isopropanol and water step. We then compared the effectiveness of these both in vitro and in vivo. Using primary mouse myoblast cultures, the manufacturer's protocol led to inconsistent and poorer cell viability when compared to the sonication protocol (p = 0.0002 at 48 h after indirect exposure). Subdermal implantation of MED610 into nude rats demonstrated a significant foreign body response with a greater number of giant cells (p = 0.0161) and foreign bodies (p = 0.0368) when compared to the sonication protocol, which was comparable to the control (sham) groups. These results present an improved, cytocompatible cleaning protocol of printable photopolymers to facilitate creative 3D-printed custom designs for cell culture systems for both in vitro and in vivo tissue engineering applications.

Economic and public health impact of decentralized HIV viral load testing: A modelling study in Kenya.

Kenya has the world's 4th largest HIV burden. Various strategies to control the epidemic have been implemented, including the implementation of viral load (VL) testing to monitor HIV patients on ARVs. Like many resource limited settings, Kenya's healthcare system faces serious challenges in effectively providing quality health services to its population. Increased investments to strengthen the country's capacity to diagnose, monitor and treat diseases, particularly HIV and TB, continue to be made but are still inadequate in the face of global health goals like the UNAIDS 90:90:90 which require scaling up of VL tests amid existing constraints. In Kenya, there is an increase in the demand for VL tests amidst these existing constraints. The GeneXpert system is a diagnostic point-of-care technology that can quantify, amongst others, HIV VL. Currently, GeneXpert technology is widely distributed in Kenya for testing of tuberculosis. This study aimed to determine the economic and public health impact of incorporating VL test modules on the existing GeneXpert infrastructure. Markov models were constructed for different populations (non-pregnant adults, pregnant women and children). The scenarios analysed were 100% centralized VL testing compared to 50% GeneXpert plus 50% centralized VL testing, with time horizons of 5 years for the adult and child populations, and 31 months for the pregnant population. Incremental effectiveness was measured in terms of the number of HIV transmissions or opportunistic infections avoided when implementing the GeneXpert scenario compared to a 100% centralized scenario. The model indicated that, for all three populations combined, the GeneXpert scenario resulted in 117 less HIV transmissions and 393 less opportunistic infections. The cost decreased by $21,978,755 for the non-pregnant and pregnant adults and $22,808,533 for non-pregnant adults, pregnant adults and children. The model showed that GeneXpert would cost less and be more effective in terms of total cost per HIV transmission avoided and the total cost per opportunistic infection avoided, except for the pregnant population, when considered separately.

Long-term outcomes of saline boluses in very preterm infants.

BACKGROUND: Normal saline bolus is commonly used in clinical practice for treating hypotension in very preterm infants during resuscitation at an early age despite the paucity of high quality evidence supporting this practice. OBJECTIVES: To determine the effects of early (<7 days after birth) saline boluses given to very preterm infant (VPI) from 23 to 31 weeks GA. METHOD: This is a population-based cohort analysis of the use of normal saline boluses given to VPI. The outcomes were extracted from the Perinatal Follow-Up Program Database which included all VPI from Halifax County admitted to the NICU at the IWK Health Centre, Halifax, Nova Scotia, Canada between January 2006 to December 2010. We excluded infants with major congenital anomalies and those not offered resuscitation in the delivery room. Our primary outcome was the composite of death or disability by 18-36 months while secondary outcomes were neonatal death, BPD, CP, IVH, PVL, ROP, BSITD III (Bayley Scales of Infant and Toddler Development®, Third Edition) Cognitive, Motor and Language score. RESULTS: Death or disability in those who received saline bolus occurred in 15 (53.6%) compared with 9 (32.1%) in non saline group. Significantly higher rates of CP (p = 0.04), lower scores on the BSITDIII for motor (p = 0.04) and language scales (p = 0.03) were noted for infants who received saline boluses. Cognitive scores approached significance (p = 0.05) with lower scores in the saline bolus group. CONCLUSION: Significant differences were found between the two groups in terms of long term neurodevelopmental outcome and one of the short-term outcome (i.e. BPD). Given the limitations of this retrospective study and the small sample size, a larger cohort from Canadian Neonatal Network database is warranted to evaluate the effects of using normal saline boluses during early life on neurodevelopmental.

Efficacy of tofacitinib in patients with rheumatoid arthritis stratified by background methotrexate dose group.

Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This post hoc analysis investigated the effect of methotrexate (MTX) dose on the efficacy of tofacitinib in patients with RA. ORAL Scan (NCT00847613) was a 2-year, randomized, Phase 3 trial evaluating tofacitinib in MTX-inadequate responder (IR) patients with RA. Patients received tofacitinib 5 or 10 mg twice daily (BID), or placebo, with low (≤12.5 mg/week), moderate (>12.5 to <17.5 mg/week), or high (≥17.5 mg/week) stable background MTX. Efficacy endpoints (at months 3 and 6) included American College of Rheumatology (ACR) 20/50/70 response rates, and mean change from baseline in Clinical Disease Activity Index (CDAI), Disease Activity Score in 28 joints (DAS28)-4(erythrocyte sedimentation rate [ESR]), Health Assessment Questionnaire-Disability Index (HAQ-DI), and modified Total Sharp score. 797 patients were treated with tofacitinib 5 mg BID (N = 321), tofacitinib 10 mg BID (N = 316), or placebo (N = 160); 242, 333, and 222 patients received low, moderate, and high MTX doses, respectively. At months 3 and 6, ACR20/50/70 response rates were greater for both tofacitinib doses vs placebo across all MTX doses. At month 3, mean changes from baseline in CDAI and HAQ-DI were significantly greater for both tofacitinib doses vs placebo, irrespective of MTX category; improvements were maintained at month 6. Both tofacitinib doses demonstrated improvements in DAS28-4(ESR), and less structural progression vs placebo, across MTX doses at month 6. Tofacitinib plus MTX showed greater clinical and radiographic efficacy than placebo in MTX-IR patients with RA, regardless of MTX dose.
