RESUMO

OBJECTIVE: To assess parent psychological distress in families of children with common chronic health conditions (CHC) and to explore relationships between parent psychological distress, unmet supportive care needs and children's quality of life (QoL). METHOD: Cross-sectional study involving parents of children diagnosed with a common CHC between 0 and 12 years of age and who had received treatment within the last 5 years. Eligible parents completed an online survey, that included the Depression Anxiety Stress Scale (DASS-21) assessing distress in parents and a 34-item assessment of unmet supportive care needs across 6 domains. Parents completed ratings of their child's current functioning (QoL) using the 23-item PedsQL. Multivariable regression models examined the relative association between unmet needs, children's QoL and parents' depression, anxiety, and stress. RESULTS: The sample consisted of 194 parents of children with congenital heart disease (n=97; 50%), diabetes (n=50; 26%), cancer (n=39; 20%), and asthma (n=8; 4%). A significant proportion of parents had moderate-severe symptoms of depression (26%), anxiety (38%), and stress (40%). Of the PedsQL scales, the poorest outcomes were found for emotional and school functioning. Multivariable analyses showed that both higher unmet needs and poorer child emotional functioning were associated with parent depression, anxiety, and stress symptoms. CONCLUSION: Evidence linking parent distress symptoms to higher unmet needs and poorer child emotional functioning suggests these factors may be targets for interventions to alleviate parent distress. Longitudinal research using larger samples is required to replicate findings, and clarify the magnitude and direction of associations.

RESUMO

BACKGROUND: This study aimed to examine how hip offset (HO) and surgical approach affect gait biomechanics following total hip arthroplasty (THA). METHODS: There were 55 THA patients assigned to 3 groups based on surgical approach (ANT: anterior, LAT: lateral, or POS: posterior) and HO difference (large HO: >5 millimeters (mm), small HO; <5 mm, or normal; between +3 mm and -3 mm). Kinematics and kinetics were recorded using motion capture and force plate data. Group differences were assessed using statistical parametric mapping. RESULTS: The ANT group demonstrated more normal sagittal plane kinematics and kinetics. No frontal plane kinematic differences were found, but the LAT group displayed more normal frontal plane kinetics. The LAT group displayed a slower walking speed than the ANT group, and the LAT and POS groups used a shorter stride/step length than the control group. The large HO group showed fewer differences in sagittal plane kinematics and kinetics than the small HO and normal groups. No frontal plane kinematic differences were observed, but the normal group demonstrated more significant differences than the large HO and small HO groups. No significant differences were found between any of the HO patient groups. CONCLUSION: Anterior and lateral approaches led to more normal gait biomechanics in sagittal kinematics and frontal kinetics, respectively, but only the ANT group exhibited spatiotemporal gait parameters within normal ranges. Hip offset differences greater or less than 5 mm do not significantly change gait patterns. Surgical approach plays a greater role than HO reconstruction in producing more normal gait biomechanics following THA.

RESUMO

BACKGROUND: Many patients report more difficulty when descending stairs compared to level walking after total knee arthroplasty (TKA). Different implant designs can affect knee biomechanics and muscle activity during gait, but their effect during stair descent is unclear. The purpose of this study was to evaluate knee biomechanics and muscle activations of quadriceps, hamstrings, and gastrocnemius muscles during a stair descent task in patients who underwent TKA with either a posterior stabilized (PS) or medial ball-and-socket (MBS) implant and to compare them to a group of healthy controls. METHODS: There were 28 TKA patients who were randomized to either an MBS (n = 14) or PS (n = 14) implant and were compared with 14 controls. Patients visited the biomechanics lab approximately 12 months after TKA, where knee biomechanics and muscle activity were measured as they descended a three-step staircase. RESULTS: Compared to the MBS and control groups, the PS group descended the stairs with a reduced knee flexion angle and greater hamstring muscle activation throughout single limb support. Knee joint moments and power were similar between the MBS and PS groups, but neither reached the level of the control group. CONCLUSION: Lower knee flexion angles and increased hamstring muscle activity indicated that the PS group descended the stairs with a stiffer knee gait pattern than the MBS group. The MBS implant design may provide additional stability as patients require less muscle activity than the PS group.

RESUMO

Despite growing research linking childhood traumatic brain injury (TBI) with reduced wellbeing, self-esteem, and psycho-social health, very few studies have examined self-esteem and its correlates in young adult survivors of childhood TBI. This very-long-term follow-up study evaluated self-esteem in 29 young adults with a history of childhood TBI (M time since injury = 13.84 years; SD = 0.74), and 10 typically developing controls (TDCs). All participants were originally recruited into a larger, longitudinal case-control study between 2007 and 2010. In the current follow-up study, both groups completed well-validated measures of self-esteem and mental health in young adulthood. Although group means for self-esteem did not significantly differ between TBI and TDC groups, a higher proportion of TBI participants rated their self-esteem in the clinical range (TBI group = 17%; TDC group = 0%). While self-esteem was not significantly associated with injury or pre-injury child or family characteristics, lower self-esteem was significantly correlated with greater concurrent feelings of loneliness (p = 0.007) and higher concurrent mood symptoms (p < 0.001).Our results suggest that social isolation and low mood may represent meaningful targets for psycho-social interventions to address poor self-worth in young adults with a history of childhood TBI.

RESUMO

This prospective cohort study aimed to evaluate the potential role of injury, socio-demographic and individual psychological factors in predicting long-term fatigue outcomes in young adult survivors of childhood TBI at 16-years post-injury. The study included 51 young adults diagnosed with childhood TBI from 2-12 years of age. Twenty age-and-sex-matched controls were included for comparison. Findings showed that almost one-in-four TBI participants (24%) endorsed clinically elevated fatigue at 16-years post-injury. Despite the relatively large proportion of TBI participants endorsing clinically significant fatigue, group comparisons revealed that the TBI and control groups did not significantly differ on fatigue symptom severity or rates of clinically elevated fatigue. For the TBI group, post-injury fatigue was significantly associated with socio-demographic and psychological factors, including lower educational level, higher depression symptom severity, and more frequent substance use. Higher fatigue was also associated with lower self-reported quality of life (QoL) in the physical, psychological, and environmental domains, even after controlling for depressive symptom severity, socio-demographic, and injury-related factors. Overall, findings show that a substantial proportion of young adults with a history of childhood TBI experience clinically elevated fatigue at 16-years post-injury. Identification and treatment of modifiable risk-factors (e.g. depression symptoms, substance use) has potential to reduce fatigue.

RESUMO

BACKGROUND: Psychosocial deficits, such as emotional, behavioral and social problems, reflect the most common and disabling consequences of pediatric traumatic brain injury (TBI). Their causes and recovery likely differ from physical and cognitive skills, due to disruption to developing brain networks and the influence of the child's environment. Despite increasing recognition of post-injury behavioral and social problems, there exists a paucity of research regarding the incidence of social impairment, and factors predicting risk and resilience in the social domain over time since injury. METHODS: Using a prospective, longitudinal design, and a bio-psychosocial framework, we studied children with TBI (n = 107) at baseline (pre-injury function), 6 months, 1 and 2-years post-injury. We assessed intellectual ability, attention/executive function, social cognition, social communication and socio-emotional function. Children underwent structural magnetic resonance imaging (MRI) at 2-8 weeks post-injury. Parents rated their child's socio-emotional function and their own mental health, family function and perceived burden. RESULTS: We distinguished five social recovery profiles, characterized by a complex interplay between environment and pre- and post-TBI factors, with injury factors playing a lesser role. Resilience in social competence was linked to intact family and parent function, intact pre-injury adaptive abilities, post-TBI cognition and social participation. Vulnerability in the social domain was related to poor pre- and post-injury adaptive abilities, greater behavioral concerns, and poorer pre- and post-injury parent health and family function. CONCLUSIONS: We identified five distinct social recovery trajectories post-child-TBI, each characterized by a unique biopsychosocial profile, highlighting the importance of comprehensive social assessment and understanding of factors contributing to social impairment, to target resources and interventions to children at highest risk.

RESUMO

BACKGROUND: Despite a well-established link between childhood traumatic brain injury (TBI) and elevated secondary attention-deficit/hyperactivity disorder (s-ADHD) symptomology, the neurostructural correlates of these symptoms are largely unknown. Based on the influential 'triple-network model' of ADHD, this prospective longitudinal investigation aimed to (i) assess the effect of childhood TBI on brain morphometry of higher-order cognitive networks proposed to play a key role in ADHD pathophysiology, including the default-mode network (DMN), salience network (SN) and central executive network (CEN); and (ii) assess the independent prognostic value of DMN, SN and CEN morphometry in predicting s-ADHD symptom severity after childhood TBI. METHODS: The study sample comprised 155 participants, including 112 children with medically confirmed mild-severe TBI ascertained from consecutive hospital admissions, and 43 typically developing (TD) children matched for age, sex and socio-economic status. High-resolution structural brain magnetic resonance imaging (MRI) sequences were acquired sub-acutely in a subset of 103 children with TBI and 34 TD children. Parents completed well-validated measures of ADHD symptom severity at 12-months post injury. RESULTS: Relative to TD children and those with milder levels of TBI severity (mild, complicated mild, moderate), children with severe TBI showed altered brain morphometry within large-scale, higher-order cognitive networks, including significantly diminished grey matter volumes within the DMN, SN and CEN. When compared with the TD group, the TBI group showed significantly higher ADHD symptomatology and higher rates of clinically elevated symptoms. In multivariable models adjusted for other well-established risk factors, altered DMN morphometry independently predicted higher s-ADHD symptomatology at 12-months post-injury, whilst SN and CEN morphometry were not significant independent predictors. CONCLUSIONS: Our prospective study findings suggest that neurostructural alterations within higher-order cognitive circuitry may represent a prospective risk factor for s-ADHD symptomatology at 12-months post-injury in children with TBI. High-resolution structural brain MRI has potential to provide early prognostic biomarkers that may help early identification of high-risk children with TBI who are likely to benefit from early surveillance and preventive measures to optimise long-term neuropsychiatric outcomes.

RESUMO

BACKGROUND AND AIMS: Unmet supportive care needs (SCN) refer to perceived gaps in the support parents want to manage caregiving activities for children with chronic health conditions (CHC) and the support received. This review aims to systematically identify the unmet SCN of families with children living with five common paediatric CHC and characterise the assessment tools used to measure SCN. DESIGN: Systematic review methodology with narrative synthesis of data. Reporting followed the PRISMA statement guidelines. METHOD: Literature searches were conducted in electronic databases Medline complete, PsycINFO, CINHAL and EMBASE to retrieve relevant articles published between 1990 and July 2022. Eligible studies involved (i) children aged 0-18 years diagnosed with either of cancer, congenital heart disease (CHD), diabetes, asthma, renal disease and (ii) assessment of unmet SCN. Studies involving children with genetic or developmental conditions were excluded. The methodological quality of studies was assessed using JBI assessment tool. RESULTS: Of 6223 articles screened, 34 papers were included (25 quantitative, 5 qualitative and 4 mixed design). Most papers explored unmet needs of families with cancer (n = 26). The remaining articles concerned CHD (n = 5), asthma (n = 2) and mixed CHC (n = 1, renal failure, and diabetes). Information (e.g. treatment, lifestyle, etc.) and health care (e.g. emotional support, practical services, etc.) were the most common unmet need domains across health conditions. A variety of methods and need assessments hampered comparisons between studies both across and within CHC. CONCLUSION: Irrespective of illness, addressing unmet informational or health care needs may help to optimise outcomes and care for children and families living with common CHC. There was considerable variation in reporting styles, study design and need assessments both within and across conditions. RELEVANCE TO CLINICAL PRACTICE: Health care professionals must routinely evaluate the type, quality and quantity of psychoeducation and support that families of children with CHC want and receive. Providing nurses with more effective strategies to assess child and family needs across a broad range of domains may help to increase understanding of where further support for families is required. PATIENT OR PUBLIC CONTRIBUTION: There was no patient or public contribution to this study as it involved a systematic review of existing literature.

RESUMO

Recent evidence suggests social cognitive deficits may be among the most profound and disabling consequences of childhood traumatic brain injury (TBI); however, it is only over the last decade that this area has received increasing research attention. This study aims to systematically review all studies reporting on the effects of childhood TBI on social cognition. Meta-analytic techniques were employed to determine the magnitude of social cognitive deficits in childhood TBI. Literature searches were conducted in electronic databases (Medline/PubMed, Scopus, Cochrane, EMBASE, PsycINFO and CINAHL) to retrieve relevant articles on social cognitive outcomes of paediatric TBI published from 2007-2019. The systematic review identified fourteen eligible studies, which examined the effect of paediatric TBI on five dimensions of social cognition, including emotion recognition or perception, theory of Mind (ToM), pragmatic language, moral reasoning, and social problem solving. Of these studies, eleven articles were included in subsequent meta-analyses, which included 482 children with TBI. Meta-analysis using a random-effects model revealed non-significant differences between TBI and typically developing (TD) control groups on measures of emotion perception or recognition. In contrast, children and adolescents with TBI performed significantly worse than control groups on ToM and pragmatic language tasks, with small and medium effect sizes, respectively (Hedge's g = -0.46; -0.73). Meta-regression indicated that post-injury social cognitive deficits were not moderated by child age. While the effect of time since injury was not statistically significant, poorer social cognitive outcomes are documented soon after injury. Despite relatively intact basic social cognitive skills (i.e. emotion perception or recognition) children and adolescents with TBI are vulnerable to deficits in higher-order aspects of social cognition, including ToM and pragmatic language. These findings underscore the importance of further research, using well-validated, standardised outcome instruments, in larger paediatric TBI samples. Furthermore, longitudinal prospective studies are needed to evaluate the respective contribution of injury and non-injury factors to individual variation in outcome and recovery of social cognition after paediatric TBI.

RESUMO

This prospective, longitudinal case-control study examined global and domain-specific aspects of self-esteem 6-months following pediatric traumatic brain injury (TBI) and evaluated the contribution of injury-related factors and parent mental health to child self-esteem. Participants included 103 children with mild-severe TBI representing consecutive admissions to the emergency department of the Royal Children's Hospital, Melbourne, Australia. Forty-three age-and-sex matched typically developing controls were recruited for comparison. Information regarding injury characteristics including age at injury and clinical indicators of TBI severity were collected for participants at recruitment, with research magnetic resonance imaging conducted 2-8 weeks later. At 6 months post-injury, children rated their global and domain-specific self-esteem (Harter Self-Perception Profile for Children), and ratings of parent mental health were collected (General Health Questionnaire). Self-esteem for behavioural and academic domains was significantly poorer for children with TBI relative to TD children. In the TBI group, higher child-rated scores of global and domain-specific aspects of self-esteem were associated with more severe TBI, presence of frontal neuropathology, younger age at injury, and lower parental symptoms of anxiety/insomnia. Given the psychological status of parents represents a potentially modifiable risk factor, it may form the target of clinical interventions designed to bolster child self-esteem following pediatric TBI.

RESUMO

PROBLEM: To examine the nature, quality, and effectiveness of Play Therapy (PT) interventions in children with chronic health conditions (CHC) and to identify the measures used to evaluate psychosocial outcomes. ELIGIBILITY CRITERIA: Systematic searches of the databases: Medline complete, PsycINFO, CINHAL, Embase and Sport Discuss were conducted to identify peer reviewed papers reporting original studies published in English between January1990 - April 2020. Studies testing any type of PT or Filial Therapy (FT) with children with CHC aged between 3 and 11 years, or their parents if FT, where outcomes were primarily psychosocial were eligible. SAMPLE AND RESULTS: The title and abstract search identified 6742 papers and six studies (three each for PT and FT) including two randomized control trials were identified as eligible for review. All FT interventions involved group-based training, while only one PT study used a group format. Outcomes for children included emotional and behavioural issues including anxiety, depression, and self-concept and while constructs were broadly comparable across studies, the measures used differed. Sample size ranged between 4 and 58. Two studies suggested positive impact of PT on depression, with one finding improvements in self-concept. Three studies with sample sizes less than 30 found no effect. CONCLUSION: With varied study designs, and small sample sizes, current evidence regarding the effectiveness of PT in improving psychosocial outcomes for children with chronic illnesses is inconclusive. IMPLICATIONS: The field should move from small underpowered studies to randomized trials with comprehensive protocols and larger sample sizes.

RESUMO

Background and Purpose: Childhood and adolescence coincide with rapid maturation of distributed brain networks supporting social cognition; however, little is known about the impact of early ischemic brain insult on the acquisition of these skills. This study aimed to examine the influence of arterial ischemic stroke (AIS) on facial emotion recognition and theory of mind (ToM) abilities of children and adolescents initially recruited to a single-center, prospective longitudinal study of recovery following AIS. Methods: The study involved 67 participants, including 30 children with AIS (mean time since stroke=5 years) and 37 age-matched typically developing controls who were assessed on measures of cognitive ToM, facial emotion recognition, and affective ToM. Acute clinical magnetic resonance imaging, including diffusion-weighted imaging sequences, were used to evaluate prospective structure-function relationships between acute lesion characteristics (size, location, and arterial territories affected) and long-term social cognitive abilities. Results: Relative to age-matched typically developing controls, children with AIS showed significantly worse performance on measures of basic facial emotion processing, cognitive ToM, and affective ToM. In univariate models, poorer ToM was associated with larger infarcts, combined cortical-subcortical pathology, and involvement of multiple arterial territories. In multivariate analyses, larger lesions and multiterritory infants were predictive of ToM processing but not facial emotion recognition. Poorer cognitive ToM predicted less frequent prosocial behavior and increased peer problems. Conclusions: Social cognitive skills appear vulnerable to disruption from early ischemic brain insult. In the first study to examine social cognition in a prospective cohort of children with AIS, our findings suggest that acute magnetic resonance imaging-based lesion characteristics may have predictive value for long-term social cognitive outcomes and may assist to identify children at elevated risk for social cognitive dysfunction.

RESUMO

BACKGROUND: Despite increasing evidence of a link between early life brain injury and anti-social behavior, very few studies have assessed factors that explain this association in children with traumatic brain injury (TBI). One hypothesis suggests that childhood TBI elevates risk for anti-social behavior via disruption to anatomically distributed neural networks implicated in executive functioning (EF). In this longitudinal prospective study, we employed high-resolution structural neuroimaging to (a) evaluate the impact of childhood TBI on regional morphometry of the central executive network (CEN) and (b) evaluate the prediction that lower EF mediates the prospective relationship between structural differences within the CEN and postinjury anti-social behaviors. METHODS: This study involved 155 children, including 112 consecutively recruited, hospital-confirmed cases of mild-severe TBI and 43 typically developing control (TDC) children. T1-weighted brain magnetic resonance imaging (MRI) sequences were acquired sub-acutely in a subset of 137 children [TBI: n = 103; TDC: n = 34]. All participants were evaluated using direct assessment of EF 6 months postinjury, and parents provided ratings of anti-social behavior 12 months postinjury. RESULTS: Severe TBI was associated with postinjury volumetric differences within the CEN and its putative hub regions. When compared with TD controls, the TBI group had significantly worse EF, which was associated with more frequent anti-social behaviors and abnormal CEN morphometry. Mediation analysis indicated that reduced EF mediated the prospective association between postinjury volumetric differences within the CEN and more frequent anti-social behavior. CONCLUSIONS: Our longitudinal prospective findings suggest that detection of neurostructural abnormalities within the CEN may aid in the early identification of children at elevated risk for postinjury executive dysfunction, which may in turn contribute to chronic anti-social behaviors after early life brain injury. Findings underscore the potential value of early surveillance and preventive measures for children presenting with neurostructural and/or neurocognitive risk factors.

RESUMO

Studies have investigated the reliability and effect of walking speed on stride time variability during walking trials performed on a treadmill. The objective of this study was to investigate the reliability of stride time variability and the effect of walking speed on stride time variability, during continuous, overground walking in healthy young adults. Participants completed: (1) 2 walking trials at their preferred walking speed on 1 day and another trial 2 to 4 days later and (2) 1 trial at their preferred walking speed, 1 trial approximately 20% to 25% faster than their preferred walking speed, and 1 trial approximately 20% to 25% slower than their preferred walking speed on a separate day. Data from a waist-mounted accelerometer were used to determine the consecutive stride times for each trial. The reliability of stride time variability outcomes was generally poor (intraclass correlations: .167-.487). Although some significant differences in stride time variability were found between the preferred walking speed, fast, and slow trials, individual between-trial differences were generally below the estimated minimum difference considered to be a real difference. The development of a protocol to improve the reliability of stride time variability outcomes during continuous, overground walking would be beneficial to improve their application in research and clinical settings.

RESUMO

OBJECTIVE: This study assessed the consequences of childhood traumatic brain injury (TBI) on sleep, fatigue, depression, and quality of life (QoL) outcomes and explored the relationships between these variables at 20 years following childhood TBI. PARTICIPANTS: We followed up 54 young adults with mild, moderate, and severe TBI, and 13 typically developing control (TDC) participants, recruited at the time of TBI. METHODS: Sleep was assessed with the Pittsburgh Sleep Quality Index and actigraphy. RESULTS: At 20 years postinjury, results showed no significant difference between whole TBI group and TDC participants on subjective sleep quality; however, the moderate TBI group reported significantly poorer subjective sleep quality compared to those with severe TBI. Poorer subjective sleep was associated with increased symptoms of fatigue, depression, and poorer perceptions of General Health in the TBI group. Actigraphic sleep efficiency, fatigue, depression, and QoL outcomes were not significantly different between TBI and TDC or among TBI severity groups. CONCLUSIONS: These preliminary findings underscore associations between subjective sleep disturbance, fatigue, depression, and QoL in this TBI sample, and mostly comparable outcomes in sleep, fatigue, depression, and QoL between the TBI and TDC groups. Further research is required to clarify these findings.

RESUMO

In a subset of dairy cows, prolonged pathological uterine inflammation results in purulent vaginal discharge (PVD), which can have negative consequences for both fertility and milk production. However, unlike for intensive systems, analysis of the effects of PVD in predominantly pasture-based herds is limited. The objective of this study was to assess the effect of PVD in spring-calving, pasture-based dairy cows on production and reproduction indices, stratified according to previous full-lactation milk yield. We assessed clinical disease as defined by vaginal mucus score (VMS) in 440 Holstein-Friesian cows from 5 farms. Cows were categorized as healthy (VMS 0) or having PVD (VMS 1-3) at 21 d postpartum. We recorded 305-d milk, milk protein, and milk fat yields (kg) before and after disease diagnosis, as well as fertility data, such as services per conception and the calving-conception period (CCP). Using SAS 9.4 (SAS Institute Inc., Cary, NC), we analyzed data using PROC MIXED, PROC PHREG, and PROC LOGISTIC to determine the least squares means differences and hazard and odds ratios between the groups, respectively. Overall, a 60% prevalence of PVD was recorded at 21 d postpartum. Milk yield and milk constituents were similar between all VMS categories and between healthy cows and cows with PVD. Although cows in the 4 VMS categories had statistically similar CCP, cows with PVD had a significantly longer CCP than healthy cows on average (9 d). The hazard ratio for cows with PVD was 0.66, indicating a 34% higher risk of a prolonged CCP than healthy cows. Odds ratio analysis determined that cows with PVD were 3 times more likely not to conceive at all, twice as likely not to conceive at first service, twice as likely not to conceive by 100 d postpartum, and 3 times more likely to fail to conceive before 150 d postpartum compared with healthy cows. Cows were retrospectively categorized as having low or high milk yield, based on whether they were above or below the median 305-d milk yield of the study population (6,571 kg) in the lactation before vaginal mucus scoring. Based on a univariate odds ratio, high-yield cows were 1.6 times more likely to present with PVD in the subsequent lactation. The number of services per conception did not differ between healthy and PVD cows in the low- and high-yield groups. In the high-yield group, cows with PVD were 4.9 times more likely not to conceive, 2.7 times more likely to require multiple services to conceive, 2.1 times more likely to remain not pregnant by 100 d postpartum, and 4.4 times more likely to remain not pregnant by 150 d postpartum. The CCP was also significantly longer in cows with PVD than their healthy counterparts (115.9 ± 4.9 and 104 ± 7.4 d, respectively). In conclusion, PVD significantly increased the CCP in all cows, but to a greater extent in cows with a high milk yield in the lactation before disease diagnosis.

RESUMO

BACKGROUND: The safety of long-acting ß-agonists added to inhaled corticosteroids for the treatment of persistent asthma has been controversial. OBJECTIVE: We sought to determine whether administering formoterol in combination with mometasone furoate increases the risk of serious asthma outcomes (SAOs) compared with mometasone furoate alone. This clinical trial is registered as NCT01471340. METHODS: We conducted a 26-week, randomized, double-blind trial in adolescent and adult patients (≥12 years) with persistent asthma in 35 countries with the primary objective of evaluating whether mometasone furoate-formoterol increases the risk of SAOs (adjudicated hospitalization, intubation, or death) compared with mometasone furoate alone. The key efficacy end point was asthma exacerbation (composite of hospitalization of ≥24 hours, emergency department visits of <24 hours requiring systemic corticosteroids, or use of systemic corticosteroids for ≥3 consecutive days). RESULTS: Among 11,729 patients (mometasone furoate-formoterol, n = 5,868; mometasone furoate, n = 5,861), a total of 81 SAOs, all asthma-related hospitalizations, were observed in 71 patients: 45 events from 39 patients receiving mometasone furoate-formoterol and 36 events from 32 patients receiving mometasone furoate. The hazard ratio for the first SAO in the mometasone furoate-formoterol versus mometasone furoate group was 1.22 (95% CI, 0.76-1.94; P = .411). Asthma exacerbation occurred in 1,487 patients: 708 receiving mometasone furoate-formoterol and 779 receiving mometasone furoate. The hazard ratio for the first asthma exacerbation in the mometasone furoate-formoterol versus mometasone furoate group was 0.89 (95% CI, 0.80-0.98; P = .021). CONCLUSIONS: The addition of formoterol to mometasone furoate maintenance therapy did not increase the risk of serious asthma-related events and reduced the risk of asthma exacerbation.

RESUMO

Executive functions (EFs), such as inhibition and cognitive flexibility, are essential for everyday functioning, including regulation of socially appropriate emotional responses. These skills develop during childhood and continue maturing into early adulthood. The current study aimed to investigate the very long-term impact of childhood traumatic brain injury (TBI) on inhibition and cognitive flexibility, and to examine whether global white matter is associated with these abilities. Twenty-eight young adult survivors of childhood TBI (mean age at 16-year follow-up = 21.67 years, SD = 2.70) and 16 typically developing controls (TDCs), group-matched for age, sex, and socioeconomic status, completed tests of inhibition and cognitive flexibility and underwent structural MRI. Survivors of childhood TBI did not significantly differ from TDCs on EF or white matter volume. However, the relationship between EF and white matter volume differed between survivors of TBI and TDCs. Survivors of TBI did not mimic the brain behavior relationship that characterized EF in TDCs. The inverse brain behavior relationship, exhibited by childhood TBI survivors, suggests disruptions in the whole brain underpinning EF following childhood TBI.

RESUMO

INTRODUCTION AND HYPOTHESIS: Treating pelvic organ prolapse (POP) with uterine conservation and sacral hysteropexy has uncertain subjective and objective outcomes. We sought to compare laparoscopic sacral hysteropexy with laparoscopic sacrocolpopexy/total laparoscopic hysterectomy (TLH with LSC). METHODS: Clinical data of 34 patients who underwent TLH with LSC and 65 patients who underwent laparoscopic sacral hysteropexy performed by the same group of surgeons between January 2008 and December 2013 were reviewed retrospectively. The primary outcome was subjective satisfaction rate based upon validated questionnaire (Patient Global Impression of Change [PGI-C]). Secondary outcomes were: anatomical cure, impact on quality of life based upon validated questionnaires (pelvic floor distress inventory-short form 20 [PFDI-20], Pelvic Floor Impact Questionnaire 7 [PFIQ-7], and Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 [PISQ-12]), surgical complications, and cost. RESULTS: After a mean follow-up of 33 months, the subjective satisfaction rate was significantly higher in the TLH with LSC cohort (92.3% vs 100%; p < 0.001). The POP-Q scores in both groups were significantly improved postoperatively. However, the anatomical cure in the two groups (72.3% vs 88.2%; p = 0.07) did not differ significantly The postoperative PFIQ-7 and PFDI-20 scores were significantly better in the TLH with LSC cohort than in the laparoscopic sacral hysteropexy cohort (p = 0.043 and p = 0.035 respectively). CONCLUSIONS: Relative to laparoscopic sacral hysteropexy, the TLH with LSC approach provides similar anatomical results, excellent patient satisfaction, and improved quality of life scores.

RESUMO

Childhood and adolescence are critical periods for maturation of neurobiological processes that underlie complex social and emotional behavior including Theory of Mind (ToM). While structural correlates of ToM are well described in adults, less is known about the anatomical regions subsuming these skills in the developing brain or the impact of cerebral insult on the acquisition and establishment of high-level social cognitive skills. This study aimed to examine the differential influence of age-at-insult and brain pathology on ToM in a sample of children and adolescents with traumatic brain injury (TBI). Children and adolescents with TBI (n = 112) were categorized according to timing of brain insult: (i) middle childhood (5-9 years; n = 41); (ii) late childhood (10-11 years; n = 39); and (iii) adolescence (12-15 years; n = 32) and group-matched for age, gender, and socioeconomic status to a typically developing (TD) control group (n = 43). Participants underwent magnetic resonance imaging including a susceptibility-weighted imaging (SWI) sequence 2-8 weeks postinjury and were assessed on a battery of ToM tasks at 6- and 24-months after injury. Results showed that for adolescents with TBI, social cognitive dysfunction at 6- and 24-months postinjury was associated with diffuse neuropathology and a greater number of lesions detected using SWI. In the late childhood TBI group, we found a time-dependent emergence of social cognitive impairment, linked to diffuse neuropathology. The middle childhood TBI group demonstrated performance unrelated to SWI pathology and comparable to TD controls. Findings indicate that the full extent of social cognitive deficits may not be realized until the associated skills reach maturity. Evidence for brain structure-function relationships suggests that the integrity of an anatomically distributed network of brain regions and their connections is necessary for the acquisition and establishment of high-level social cognitive skills.
