Impaired vision in children prenatally exposed to methadone: an observational cohort study. Eye (Lond) 2024; 38:118-126. [PMID: 37402864 PMCID: PMC10764882 DOI: 10.1038/s41433-023-02644-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 06/05/2023] [Accepted: 06/15/2023] [Indexed: 07/06/2023] Open
Abstract
BACKGROUND/OBJECTIVES To examine prevalence of failed visual assessment at 8-10 years in children born to methadone-maintained opioid dependent (MMOD) mothers and relate this to known in utero substance exposure. SUBJECTS/METHODS Follow up of observational cohort study of methadone-exposed and comparison children matched for birthweight, gestation and postcode of residence at birth. Participants were 144 children (98 exposed, 46 comparison). Prenatal drug exposure was previously established via comprehensive maternal and neonatal toxicology. Children were invited to attend for visual assessment and casenotes were reviewed. Presence of acuity poorer than 0.2 logMAR, strabismus, nystagmus and/or impaired stereovision constituted a 'fail'. Fail rates were compared between methadone-exposed and comparison children after adjusting for known confounding variables. RESULTS 33 children attended in person: data were also derived from casenote review for all children. After controlling for maternal reported tobacco use, methadone-exposed children were more likely to have a visual 'fail' outcome, adjusted odds ratio 2.6, 95% CI 1.1-6.2; adjusted relative risk 1.8 (95% CI 1.1-3.4). Visual 'fail' outcome rates did not differ between methadone-exposed children who had (n = 47) or had not (n = 51) received pharmacological treatment for neonatal abstinence/opioid withdrawal syndrome (NAS/NOWS); fail rate 62% vs 53% (95% CI of difference-11-27%). CONCLUSIONS Children born to MMOD mothers are almost twice as likely as unexposed peers to have significant visual abnormalities at primary school age. Prenatal methadone exposure should be considered in the differential diagnosis of nystagmus. Findings support visual assessment prior to school entry for children with any history of prenatal opioid exposure. TRIAL REGISTRATION The study was prospectively registered on ClinicalTrials.gov (NCT03603301), https://clinicaltrials.gov/ct2/show/NCT03603301 .

Specialist care of children with complex needs: Insights from comparison of child development and child mental health clinics. J Paediatr Child Health 2022; 58:2058-2067. [PMID: 36070197 DOI: 10.1111/jpc.16161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2021] [Revised: 07/22/2022] [Accepted: 07/28/2022] [Indexed: 11/28/2022]
Abstract
AIM Paediatricians and child psychiatrists review children with complex comorbidity, noting similarities between tertiary Child Development Service (CDS) and Child and Youth Mental Health Service (CYMHS) cohorts. Mental health comorbidity is common in developmental services. Developmental comorbidity in mental health cohorts is uncharacterised. The study aimed to describe CDS and CYMHS cohorts using measures of child development, mental health, physical health and psychosocial risk. METHODS A questionnaire was completed by parents of CDS and CYMHS new clients aged 4-11. It included measures of mental health symptoms, child development, physical health, stressful life events, family functioning, parent mental health and socio-economic variables. Sample rates were compared to population norms. CDS and CYMHS cohorts were compared. RESULTS The study population had elevated rates of psychosocial risk, family dysfunction, physical illness, developmental risk and mental health symptoms. CDS had higher levels of developmental risk and family dysfunction. Most CDS clients (81%) had mental health difficulties. CYMHS clients were older, and had more mental health symptoms, stressful life events and child safety contact; 81% of CYMHS clients demonstrated developmental risk. CDS and CYMHS had similar socio-demographic profiles and parent mental health difficulties, and similarly high rates of physical health problems. CONCLUSIONS Consideration should be given to mental health screening and support in CDS, and to developmental screening in CYMHS. Both services support at-risk children with complex developmental, mental health and physical co-morbidity necessitating shared approaches to clinical and population health, including care integration, and collaborative cross-disciplinary models of service provision and training, and advocacy.

Social environmental impact of COVID-19 and erectile dysfunction: an explorative review. J Endocrinol Invest 2022; 45:483-487. [PMID: 34559402 PMCID: PMC8461150 DOI: 10.1007/s40618-021-01679-1] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Accepted: 09/15/2021] [Indexed: 12/22/2022]
Abstract
BACKGROUND To date, no attempt has been made to collate literature on the relationship between the social environmental impact of COVID-19 and erectile dysfunction. The aim of this explorative review was to assess and compare the prevalence of erectile dysfunction (ED) in male healthcare workers and males during the COVID-19 pandemic. METHODS A systematic review of major databases from inception to February 2021 was conducted. Prevalence data were extracted, and a random-effects meta-analysis was undertaken. OUTCOMES The pooled prevalence of ED amongst healthcare workers working in COVID-19 specific environments, and non-healthcare during the COVID-19 pandemic. RESULTS Of 52 initial studies, six were included for the final analysis. The pooled prevalence of ED in healthcare workers working in a COVID-19 environment was 63.6% (95% CI 20.3-92.3%), and in non-healthcare workers during the COVID-19 pandemic was 31.9% (95% CI 19.5-47.6%). CONCLUSION The prevalence of ED in healthcare workers working in COVID-19 environments was higher than representative samples and is of concern. Sexual health (and by extension, overall health), should be a priority when considering ways to care for this population. Considering the social environmental impact of COVID-19 on sexual health and in particular on ED, it is important to provide adequate psychological support systems and to promote quality of life with particular attention to sexual health.

Abstract
OBJECTIVES The relationship between consuming ≥2 servings of fruits and ≥3 servings of vegetables a day, which has been identified as optimal for health (i.e., adequate fruit/vegetable consumption), and non-communicable diseases (NCDs) in low- and middle-income countries (LMICs) is largely unknown. Therefore, using data from six LMICs, we investigated the independent association between inadequate fruit/vegetable consumption and 12 NCDs, and estimated the prevalence of inadequate fruit/vegetable consumption among people with NCDs. DESIGN AND SETTING Cross-sectional, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. PARTICIPANTS Data on 34129 individuals aged ≥50 years were analyzed [mean (SD) age 62.4 (16.0); maximum age 114 years; 52.1% females]. MEASUREMENTS Information on the number of servings of fruits and vegetables consumed on a typical day was self-reported. Twelve NCDs were assessed. Multivariable logistic regression analysis was conducted. RESULTS Overall, 67.2% had inadequate fruit/vegetable consumption. Inadequate fruit/vegetable consumption was independently associated with significantly higher odds for chronic lung disease (OR=1.25), diabetes (OR=1.45), hearing problems (OR=1.75), and visual impairment (OR=2.50). The prevalence of inadequate fruit/vegetable consumption was particularly high among people with visual impairment (92.5%), depression (90.5%), asthma (79.8%), and hearing problems (78.4%). CONCLUSION Promotion of fruit and vegetable consumption (≥2 servings of fruits and ≥3 servings of vegetables a day) in LMICs may lead to prevention of some NCDs (e.g., diabetes, chronic lung disease). Furthermore, people with certain NCDs (e.g., visual impairment, depression) had particularly high prevalence of inadequate fruit/vegetable consumption, and it is thus important to target this population to increase fruit/vegetable consumption.

Abstract
This is the report from the fifth meeting of the Harmonising Outcome Measures for Eczema initiative (HOME V). The meeting was held on 12-14 June 2017 in Nantes, France, with 81 participants. The main aims of the meeting were (i) to achieve consensus over the definition of the core domain of long-term control and how to measure it and (ii) to prioritize future areas of research for the measurement of the core domain of quality of life (QoL) in children. Moderated whole-group and small-group consensus discussions were informed by presentations of qualitative studies, systematic reviews and validation studies. Small-group allocations were performed a priori to ensure that each group included different stakeholders from a variety of geographical regions. Anonymous whole-group voting was carried out using handheld electronic voting pads according to predefined consensus rules. It was agreed by consensus that the long-term control domain should include signs, symptoms, quality of life and a patient global instrument. The group agreed that itch intensity should be measured when assessing long-term control of eczema in addition to the frequency of itch captured by the symptoms domain. There was no recommendation of an instrument for the core outcome domain of quality of life in children, but existing instruments were assessed for face validity and feasibility, and future work that will facilitate the recommendation of an instrument was agreed upon.

Abstract
Purpose To investigate whether the observed international differences in retinopathy of prematurity (ROP) treatment rates within the Benefits of Oxygen Saturation Targeting (BOOST) II trials might have been caused by international variation in ROP disease grading. Methods Groups of BOOST II trial ophthalmologists in UK, Australia, and New Zealand (ANZ), and an international reference group (INT) used a web based system to grade a selection of RetCam images of ROP acquired during the BOOST II UK trial. Rates of decisions to treat, plus disease grading, ROP stage grading, ROP zone grading, inter-observer variation within groups and intra-observer variation within groups were measured. Results Forty-two eye examinations were graded. UK ophthalmologists diagnosed treat-requiring ROP more frequently than ANZ ophthalmologists, 13.9 (3.49) compared to 9.4 (4.46) eye examinations, P=0.038. UK ophthalmologists diagnosed plus disease more frequently than ANZ ophthalmologists, 14.1 (6.23) compared to 8.5 (3.24) eye examinations, P=0.021. ANZ ophthalmologists diagnosed stage 2 ROP more frequently than UK ophthalmologists, 20.2 (5.8) compared to 12.7 (7.1) eye examinations, P=0.026. There were no other significant differences in the grading of ROP stage or zone. Inter-observer variation was higher within the UK group than within the ANZ group. Intra-observer variation was low in both groups. Conclusions We have found evidence of international variation in the diagnosis of treatment-requiring ROP. Improved standardisation of the diagnosis of treatment-requiring ROP is required. Measures might include improved training in the grading of ROP, using an international approach, and further development of ROP image analysis software.

Abstract
BACKGROUND Postgraduate general practice training is an apprenticeship of learning to be a general practitioner by working as a general practitioner under supervision. During this apprenticeship, registrars learn the art, craft and ethics of their vocation, and how to apply clinical knowledge and skills in different contexts. OBJECTIVE This article summarises how registrars learn, and the role of general practice supervisors and training practices in supporting their education. DISCUSSION General practice supervisors form educational alliances with registrars that provide the foundation for deep and broad learning. Overseeing patient safety requires supervisors to respond to registrars' queries and monitor them proactively. Registrars learn best in practices that include them in all their work and share their expertise. Specific issues raised by teams of part-time super-visors, and by rural and remote practice, are discussed. Finally, teaching practices are recommended to seek and implement feedback from registrars.

Abstract
PurposeTo assess the diagnostic accuracy of the Edinburgh diplopia diagnostic algorithm.MethodsThis was a prospective study. Details of consecutive patients referred to ophthalmology clinics at Falkirk Community Hospital and Princess Alexandra Eye Pavilion, Edinburgh, with double vision were collected by the clinician first seeing the patient and passed to the investigators. The investigators then assessed the patient using the algorithm. An assessment of the degree of concordance between the 'algorithm assisted' diagnosis and the 'gold standard' diagnosis, made by a consultant ophthalmologist was then carried out. The accuracy of the pre-algorithm diagnosis made by the referrer was also noted.ResultsAll patients referred with diplopia were eligible for inclusion. Fifty-one patients were assessed; six were excluded. The pre-algorithm accuracy of referrers was 24% (10/41). The algorithm assisted diagnosis was correct 82% (37/45) of the time. It correctly diagnosed: cranial nerve (CN) III palsy in 6/6, CN IV palsy in 7/8, CN VI palsy in 12/12, internuclear ophthalmoplegia in 4/4, restrictive myopathy in 4/4, media opacity in 1/1, and blurred vision in 3/3. The algorithm assisted diagnosis was wrong in 18% (8/45) of the patients.ConclusionsThe baseline diagnostic accuracy of non-ophthalmologists rose from 24 to 82% when patients were assessed using the algorithm. The improvement in the diagnostic accuracy resulting from the use of the algorithm would, hopefully, result in more accurate triage of patients with diplopia that are referred to the hospital eye service. We hope we have demonstrated its potential as a learning tool for inexperienced clinicians.

Abstract
Abstract
Background:
Patients with invasive lobular carcinoma (ILC) would be expected to have favorable outcomes compared to patients with invasive ductal carcinoma (IDC) given that ILC is more often hormone receptor-positive (HR+), human epidermal growth factor receptor 2 (HER2)-negative, of lower grade, and displays decreased proliferation markers. Based on our preclinical studies showing differential hormone response in HR+ ILC vs. IDC and on recent studies suggesting differences in endocrine treatment response between patients with ILC vs. IDC, we designed a biomarker-driven, neoadjuvant window trial for newly diagnosed women with HR+, HER2-negative ILC. We hypothesize that Ki67 will be reduced by 85% in the fulvestrant arm compared with 60% and 75% reduction in the tamoxifen and anastrozole arms, respectively, and that Ki67 reduction will correlate with alterations in expression of ER and ER-regulated genes. Differential Ki67 effect will serve as a surrogate for outcome of patients with ILC on endocrine therapy.
Trial Design: This multicenter study (NCT02206984) will enroll 150 women with HR+ and HER2-negative ILC. A mandatory research breast tumor biopsy will be performed at baseline. Fifty patients will be randomized to each of three open-label treatment arms for 21 days: fulvestrant (two 250 mg IM injections on both day 1 and day 14), anastrozole (1mg orally daily), or tamoxifen (20 mg orally daily). Biomarkers of response will be assessed on baseline and post-treatment tumor tissue. Patients will proceed to definitive surgery on day 21 after study drug exposure, or they will undergo a second research breast core biopsy if further neoadjuvant treatment is planned.
Eligibility Criteria: Eligible patients include postmenopausal women with newly diagnosed, HR+, HER2-negative ILC (excluding pleomorphic subtype) measuring ≥ 1cm, with adequate organ function, ECOG PS ≥ 2, and agreeable to baseline research breast tumor biopsy.
Specific Aims: The primary endpoint is percent change from baseline to post-treatment Ki67 values in ILC tissue after 21 days of endocrine treatment. Comparisons across study arms will be made using a general linear model adjusting for institutional effect, with 80% power estimated for pairwise comparisons of log2(% staining) between treatment arms, allowing for 10% attrition. Secondary endpoints include post-therapy Ki67, and change in ER and PR protein expression by IHC. Finally, planned correlative studies include evaluation of gene expression, epigenetic markers, and DNA sequence variants in ILC tissues in an effort to identify biomarkers of endocrine response and putative drivers of endocrine resistance in ILC.
Target Accrual: This study will be open to enrollment by August 2015 at the University of Pittsburgh. Additional sites will be opened through the Translational Breast Cancer Research Consortium (TBCRC). We anticipate an accrual rate of 8 patients per month.

Abstract
PURPOSE To assess the diagnostic accuracy of the Edinburgh Red Eye Algorithm. METHODS This was a prospective study. A questionnaire was designed and made available to clinicians referring patients to the acute ophthalmology service within Edinburgh. The questionnaire involved them using the algorithm to reach a diagnosis in patients presenting with red eye(s). Patients were then referred to the emergency eye clinic and the questionnaire faxed to the clinic or sent with the patients. Patients were then examined by an experienced ophthalmologist (not blinded) to reach a 'gold standard' diagnosis. The concordance between the 'algorithm assisted' diagnosis and the 'gold standard' was then assessed. RESULTS All patients presenting with red eye(s) were eligible for inclusion. Forty-one questionnaires were completed, two were excluded. The algorithm assisted diagnosis was correct 72% (28/39) of the time. It correctly diagnosed: acute angle closure glaucoma in 100% of cases (4/4); iritis in 82% (9/11); stromal keratitis in 63% (5/8); epithelial keratitis in 70% (7/10); and infective conjunctivitis in 50% (3/6). DISCUSSION The diagnostic accuracy of The Edinburgh Red Eye Diagnostic Algorithm is 72, rising to 76% when only the most serious red eye(s) causes are included. The diagnostic accuracy of non-ophthalmologists when assessing patients presenting with red eye(s) is greater when the algorithm is used. We hope that the use of this algorithm will prevent delayed presentations of certain serious eye conditions and reduce the morbidity from delayed treatment.

Abstract
OBJECTIVE We wished to ascertain if there is an association between symptoms of attention-deficit/hyperactivity disorder (ADHD) and home environment in children with ADHD and non-ADHD siblings, controlling for other environmental measures. METHODS 96 children with ADHD combined type (ADHD-CT) and their siblings participated in the study. Parent and teacher Conners' rating scales were completed and home environment was assessed using the middle childhood and early adolescent Home Observation for Measurement of the Environment (HOME). ADHD symptoms were assessed for correlation with HOME in children with ADHD-CT and non-ADHD siblings and multiple regression analysis was used to control for gender, socio-economic status, exposure to nicotine, exposure to alcohol in utero, birth weight, gestational age, pregnancy and perinatal risk factors. The presence of oppositional disorders was assessed for association with HOME score in those with ADHD-CT. The multiple regression analysis was repeated controlling for environmental factors and for oppositional disorders in those with ADHD-CT. Oppositional symptoms were assessed for correlation with HOME score in non-ADHD siblings. RESULTS Teacher-rated hyperactive/impulsive scores correlated with HOME (r=-0.27, P < 0.01) in children with ADHD-CT. This association remained significant when other environmental factors and oppositional disorders were controlled for. Environmental factors and gender contributed to 30% of the variance of ADHD symptoms in ADHD-CT. Parent-rated hyperactive/impulsive scores also correlated with HOME (r=-0.28, P < 0.05) for non-ADHD siblings. An association between HOME and diagnosis of oppositional defiant disorder or conduct disorder was found for children with ADHD-CT and between HOME and oppositional symptoms in non-ADHD siblings. CONCLUSIONS The home environment has a small but significant association with hyperactive/impulsive symptoms in children with ADHD-CT and non-ADHD siblings. This association remained when other environmental factors were taken into account. Oppositional symptoms are associated with home environment in ADHD-CT and in non-ADHD siblings.

Abstract
BACKGROUND In 2010, Waitemata District Health Board piloted a new model of care for total hip and knee arthroplasties. The pilot was incentive based and clinically led. The participating surgeons and anaesthetists were responsible for increasing surgical throughput. The pilot aimed to increase productivity, reduce cost and increase quality for patients. AIM To compare costs and outcomes for elective hip and knee arthroplasties carried out at the pilot site (Waitakere Hospital) compared with the main District Health Board hospital site (North Shore Hospital (NSH)). METHODS A retrospective matched cohort study of hip and knee replacements discharged between 1 July 2010 and 31 March 2011, comparing costs and outcomes at the pilot site compared with the NSH site. Only non-complex procedures were included, and routinely collected data were used. RESULTS One hundred and seventy-seven hip replacements (77 NSH, 100 pilot) and 158 knee replacements (88 NSH, 70 pilot) were analysed. Total inpatient event costs were 12% and 17% lower for hip and knee replacements, respectively, at the pilot site compared with NSH. Significant reduction in operation length (39% hip, 36% knee) and length of stay (38% hip, 39% knee) were found in the pilot groups compared with NSH. CONCLUSION Implementation of an innovative new model in a public hospital setting has produced significant increases in productivity and reduced overall costs. This model could potentially be used in other public healthcare settings for non-complex elective surgery.

Abstract
We tested the hypothesis that in a genetically mixed assemblage of worker honey bees, individual workers would behave differently toward unfamiliar sisters than toward unfamiliar nonsisters. Groups of worker honey bees of mixed genetic composition were assembled by collecting pupae from separate colonies and placing the worker bees together on eclosion. A total of 10 workers, 5 from each of two kin groups, were used to form each group. When the workers were 5 days old, a worker of one of the two kin groups was introduced into the mixed group. This worker had previously been held in a group of its sisters, without contact with queen or nonsister bees. The interactions with the introduced bee indicate that in a mixed kin group, individual workers learn the composite identity of the group and do not attack unfamiliar bees differentially on the basis of kinship. However, kinship does influence the total number of interactions in which an introduced bee engages when placed in a genetically mixed group; bees interacted significantly more often with sisters than with nonsisters. There was a trend for bees to be involved in more feeding interactions with sisters. This finding indicates an ability of a bee to learn and use its own cues. In mixed groups, each bee maintains its genotypically correlated identity; the bees' odors do not comingle into a "group" or "gestalt" odor. The significance of these results is discussed in light of the genetic structure of natural colonies of honey bees.

Abstract
Aims-To investigate the pathology in patients presenting with sudden onset neurological illnesses associated with Mycoplasma pneumoniae infection.Methods-M pneumoniae infection was diagnosed by a highly rigorous interpretation of serological markers initially using complement fixation, agglutination and IgM antibodies. Confirmation of the serological diagnosis was achieved using indirect immunofluorescence for IgM, IgA, and IgG. Serum and cerebrospinal fluid (CSF) samples from these patients were examined using the polymerase chain reaction to look for evidence of M pneumoniae DNA.Results-No M pneumoniae DNA was found in any serum or CSF samples. Diagnosis of M pneumoniae infection by agglutination and complement fixation antibodies was not always confirmed by indirect immunofluorescence.Conclusion-The neurological lesions in these patients do not appear to be caused by the direct invasion of M pneumoniae into the nervous system. The lesions may be an immune response to infection. Serological diagnosis of M pneumoniae continues to be a laboratory problem.

Abstract
BACKGROUND Attention-deficit hyperactivity disorder (ADHD) is one of the most common and highly heritable child psychiatric disorders. There is strong evidence that children with ADHD show slower and more variable responses in tasks such as Go/Nogo tapping aspects of executive functions like sustained attention and response control which may be modulated by motivational factors and/or state-regulation processes. The aim of this study was (1) to determine if these executive functions may constitute an endophenotype for ADHD; (2) to investigate for the first time whether known modulators of these executive functions may also be familial; and (3) to explore whether gender has an impact on these measures. METHODS Two hundred and five children with ADHD combined type, 173 nonaffected biological siblings and 53 controls with no known family history of ADHD were examined using a Go/Nogo task in the framework of a multi-centre study. Performance-measures and modulating effects of event-rate and incentives were examined. Shared familial effects on these measures were assessed, and the influence of gender was tested. RESULTS Children with ADHD responded more slowly and variably than nonaffected siblings or controls. Nonaffected siblings showed intermediate scores for reaction-time variability, false alarms and omission errors under fast and slow event-rates. A slower event-rate did not lead to reduced performance specific to ADHD. In the incentive condition, mean reaction-times speeded up and became less variable only in children with ADHD and their nonaffected siblings, while accuracy was improved in all groups. Males responded faster, but also committed more false alarms. There were no interactions of group by gender. CONCLUSIONS Reaction-time variability and accuracy parameters could be useful neuropsychological endophenotypes for ADHD. Performance-modulating effects of incentives suggested a familially driven motivational dysfunction which may play an important role on etiologic pathways and treatment approaches for ADHD. The effects of gender were independent of familial effects or ADHD-status, which in turn suggests that the proposed endophenotypes are independent of gender.

Abstract
Children with attention deficit/hyperactivity disorder (ADHD) choose smaller sooner (SS) over larger later (LL) rewards more than controls. Here we assess the contributions of impulsive drive for immediate rewards (IDIR) and delay aversion (DAv) to this pattern. We also explore the characteristics of, and the degree of familiality in, ADHD SS responders. We had 360 ADHD probands; 349 siblings and 112 controls (aged between 6 to 17 years) chose between SS (1 point after 2 s) and LL reward (2 points after 30 s) outcomes on the Maudsley Index of Delay Aversion (Kuntsi, Oosterlaan, & Stevenson, 2001): Under one condition SS choice led to less overall trial delay under another it did not. ADHD participants chose SS more than controls under both conditions. This effect was larger when SS choice reduced trial delay. ADHD SS responders were younger, had lower IQ, more conduct disorder and had siblings who were more likely to be SS responders themselves. The results support a dual component model in which both IDIR and DAv contribute to SS choice in ADHD. SS choice may be a marker of an ADHD motivational subtype.

Abstract
It is hypothesised that autism symptoms are present in Attention-Deficit/Hyperactivity Disorder (ADHD), are familial and index subtypes of ADHD. Autism symptoms were compared in 821 ADHD probands, 1050 siblings and 149 controls. Shared familiality of autism symptoms and ADHD was calculated using DeFries-Fulker analysis. Autism symptoms were higher in probands than siblings or controls, and higher in male siblings than male controls. Autism symptoms were familial, partly shared with familiality of ADHD in males. Latent class analysis using SCQ-score yielded five classes; Class 1(31%) had few autism symptoms and low comorbidity; Classes 2-4 were intermediate; Class 5(7%) had high autism symptoms and comorbidity. Thus autism symptoms in ADHD represent a familial trait associated with increased neurodevelopmental and oppositional/conduct disorders.

Abstract
Attention deficit hyperactivity disorder (ADHD) is a discrete clinical syndrome characterized by the triad of inattention, hyperactivity, and impulsivity in the context of marked impairments. Molecular genetic studies have been successful in identifying genetic variants associated with ADHD, particularly with DSM-IV inattentive and combined subtypes. Quantitative trait locus (QTL) approaches to linkage and association mapping have yet to be widely used in ADHD research, although twin studies investigating individual differences suggest that genetic liability for ADHD is continuously distributed throughout the population, underscoring the applicability of quantitative dimensional approaches. To investigate the appropriateness of QTL approaches, we tested the familial association between 894 probands with a research diagnosis of DSM-IV ADHD combined type and continuous trait measures among 1,135 of their siblings unselected for phenotype. The sibling recurrence rate for ADHD combined subtype was 12.7%, yielding a sibling recurrence risk ratio (lambda(sib)) of 9.0. Estimated sibling correlations around 0.2-0.3 are similar to those estimated from the analysis of fraternal twins in population twin samples. We further show that there are no threshold effects on the sibling risk for ADHD among the ADHD probands; and that both affected and unaffected siblings contributed to the association with ADHD trait scores. In conclusion, these data confirm the main requirement for QTL mapping of ADHD by demonstrating that narrowly defined DSM-IV combined type probands show familial association with dimensional ADHD symptom scores amongst their siblings.

Abstract
As part of the International Multi-centre ADHD Genetics project we completed an affected sibling pair study of 142 narrowly defined Diagnostic and Statistical Manual of Mental Disorders, fourth edition combined type attention deficit hyperactivity disorder (ADHD) proband-sibling pairs. No linkage was observed on the most established ADHD-linked genomic regions of 5p and 17p. We found suggestive linkage signals on chromosomes 9 and 16, respectively, with the highest multipoint nonparametric linkage signal on chromosome 16q23 at 99 cM (log of the odds, LOD=3.1) overlapping data published from the previous UCLA (University of California, Los Angeles) (LOD>1, approximately 95 cM) and Dutch (LOD>1, approximately 100 cM) studies. The second highest peak in this study was on chromosome 9q22 at 90 cM (LOD=2.13); both the previous UCLA and German studies also found some evidence of linkage at almost the same location (UCLA LOD=1.45 at 93 cM; German LOD=0.68 at 100 cM). The overlap of these two main peaks with previous findings suggests that loci linked to ADHD may lie within these regions. Meta-analysis or reanalysis of the raw data of all the available ADHD linkage scan data may help to clarify whether these represent true linked loci.

Abstract
OBJECTIVE Performance status (PS) is an important prognostic factor in advanced ovarian cancer. The purpose of this study was to evaluate the prognostic significance of PS and quality of life (QoL) assessment on progression-free survival (PFS) and overall survival (OS) in patients with advanced ovarian cancer. METHODS We studied Canadian patients participating in an intergroup study in ovarian cancer (NCIC-OV10), which randomized patients to receive either standard chemotherapy using cisplatin/cyclophosphamide or cisplatin/paclitaxel chemotherapy. QoL was assessed using the EORTC quality of life questionnaire (QLQ-C30+3). The effects of multiple variables including the relevant clinical variables, PS and QoL scores were analyzed by Cox stepwise regression at baseline and again 3 months after completion of chemotherapy. RESULTS At baseline and at 3 months after chemotherapy, there were 151 and 93 patients respectively who completed the QLQ-C30+3 questionnaires. Baseline PS, global QoL score and treatment were independent predictors for both PFS and OS. Baseline cognitive functioning score was also an additional independent predictor for OS. At 3 months after completion of chemotherapy global QoL score, PS and grade were significant independent predictors of OS; however, only physical functioning score, emotional functioning score and tumor grade predicted for PFS. CONCLUSIONS Performance status and global quality of life scores at baseline are prognostic factors in advanced ovarian cancer for both PFS and OS. Higher baseline cognitive functioning scores were also associated with improved survival. Global QoL scores at 3 following completion of chemotherapy proved to be of prognostic significance for OS but not PFS.

Abstract
Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, starting in early childhood and persisting into adulthood in the majority of cases. Family and twin studies have demonstrated the importance of genetic factors and candidate gene association studies have identified several loci that exert small but significant effects on ADHD. To provide further clarification of reported associations and identify novel associated genes, we examined 1,038 single-nucleotide polymorphisms (SNPs) spanning 51 candidate genes involved in the regulation of neurotransmitter pathways, particularly dopamine, norepinephrine and serotonin pathways, in addition to circadian rhythm genes. Analysis used within family tests of association in a sample of 776 DSM-IV ADHD combined type cases ascertained for the International Multi-centre ADHD Gene project. We found nominal significance with one or more SNPs in 18 genes, including the two most replicated findings in the literature: DRD4 and DAT1. Gene-wide tests, adjusted for the number of SNPs analysed in each gene, identified associations with TPH2, ARRB2, SYP, DAT1, ADRB2, HES1, MAOA and PNMT. Further studies will be needed to confirm or refute the observed associations and their generalisability to other samples.

The tyrosine receptor kinase B ligand, neurotrophin-4, is not required for either epileptogenesis or tyrosine receptor kinase B activation in the kindling model. Neuroscience 2006; 141:515-20.

Abstract
The kindling model of epilepsy is a form of neuronal plasticity induced by repeated induction of pathological activity in the form of focal seizures. A causal role for the neurotrophin receptor, tyrosine receptor kinase B, in epileptogenesis is supported by multiple studies of the kindling model. Not only is tyrosine receptor kinase B required for epileptogenesis in this model but enhanced activation of tyrosine receptor kinase B has been identified in the hippocampus in multiple models of limbic epileptogenesis. The neurotrophin ligand mediating tyrosine receptor kinase B activation during limbic epileptogenesis is unknown. We hypothesized that neurotrophin-4 (NT4) activates tyrosine receptor kinase B in the hippocampus during epileptogenesis and that NT4-mediated activation of tyrosine receptor kinase B promotes limbic epileptogenesis. We tested these hypotheses in NT4-deficient mice with a targeted deletion of NT4 gene using the kindling model. The development and persistence of amygdala kindling were examined in wild type (+/+) and NT4 null mutant (-/-) mice. No differences were found between +/+ and -/- mice with respect to any facet of the development or persistence of kindling. Despite the absence of NT4, activation of the tyrosine receptor kinase B receptor in the mossy fiber pathway as assessed by phospho-trk immunohistochemistry was equivalent to that of +/+ mice. Together these findings demonstrate that NT4 is not required for limbic epileptogenesis nor is it required for activation of tyrosine receptor kinase B in hippocampus during limbic epileptogenesis.

Abstract
Turner's syndrome is one of the most common of all chromosomal abnormalities and is associated with significant ophthalmic morbidity. Turner's 1938 account included two patients with strabismus, and hitherto the condition has generated more interest among orthoptists than ophthalmologists. This systematic review of the literature seeks to redress the balance. Based on the pooled data of 274 patients with Turner's syndrome, it is the most complete evaluation so far of the prevalence and severity of ophthalmic problems in this population. This includes both a systematic review of the ophthalmic literature (via Medline) and the much larger body of work available in the orthoptic literature. Finally, we consider recent progress that enables the ophthalmologist to progress from the simple recognition of a phenotype to the correlation of genotypic variations with embryogenesis and consequent features of that phenotype.

Abstract
In 1995 and 1996, we conducted a study of the hymenopteran parasitoids of macrolepidopteran larvae in the George Washington National Forest (GWNF), Augusta County, Virginia, and the Monongahela National Forest (MNF), Pocahontas County, West Virginia. Macrolepidopteran larvae were collected from canopy foliage and from under canvas bands placed around tree boles. A total of 115 macrolepidopteran species and 5,235 individual larvae were reared. Forty-two percent (2,221) of the larvae were gypsy moth, Lymantria dispar (L.) (Lymantriidae). A total of 43 primary and secondary (hyperparasitoid) hymenopteran parasitoid species were reared from 46 macrolepidopteran species. Hymenopteran families represented included Ichneumonidae (23 species), Braconidae (19), Eulophidae (6), Perilampidae (1), and Trigonalidae (1). We reared 41 and 28 parasitoid species from the GWNF and the MNF, respectively, with 19 species reared from both forests. Many parasitoid species were collected infrequently, suggesting that they are relatively rare on the sampled hosts. The introduced species Cotesia melanoscela (Ratzeburg) (Braconidae), and Euplectrus bicolor (Swederus) (Eulophidae) were among the most commonly reared parasitoids, the latter reared from native hosts. The four most commonly reared native parasitoids were Meteorus hyphantriae, Riley (Braconidae), Microplitis near hyphantriae (Ashmead) (Braconidae), Aleiodes preclarus Marsh & Shaw, and Euplectrus maculiventris (Westwood) (Eulophidae). A total of 53 new hymenopteran parasitoid-macrolepidopteran host records were documented. Results from this study will be used to evaluate long-term treatment effects of regional applications of Bacillus thuringiensis kurstaki, and the gypsy moth fungus Entomophaga maimaiga Humber, Shimazu & Soper on hymenopteran parasitoids of macrolepidopteran larvae.

Abstract
BACKGROUND The failure of patients to take medicines in a way that leads to clinical benefit is a major challenge. A consensus has emerged that, on average, compliance sufficient to obtain therapeutic objectives occurs about half the time, with noncompliance contributing to therapeutic failure in the other half. These figures refer to simple oral regimens. There has been little work assessing compliance/concordance with complex treatment regimens for atopic eczema. Asthma schools led by specialist nurses have been shown to improve knowledge, use of therapies and clinical outcome. OBJECTIVES To determine the effect of education and demonstration of topical therapies by specialist dermatology nurses on therapy utilization and severity of atopic eczema. METHODS Fifty-one children with atopic eczema attending a paediatric dermatology clinic were followed for up to 1 year. At each visit the parent's knowledge about atopic eczema and its treatment and therapy utilization was recorded. The severity of the eczema was recorded using the six area, six sign atopic dermatitis severity score (SASSAD) and parental assessment of itch, sleep disturbance and irritability. At the first visit a specialist dermatology nurse explained and demonstrated how to use all of the topical treatments. This education was repeated at subsequent visits depending on the knowledge of the parent. RESULTS At baseline less than 5% of parents had received/recalled receiving any explanation of the causes of eczema or demonstration of how to apply topical treatments. The eczema was poorly controlled in all children (mean SASSAD 42.9). Of the children, 24% were not being treated with any emollient cream/ointment; the mean use was 54 g weekly. Of the children, 25% were being inappropriately treated with potent or very potent topical steroids. Following repeated education and demonstration of topical therapies by a specialist dermatology nurse, there was an 89% reduction in the severity of the eczema. The main change in therapy utilization was an 800% increase in the use of emollients (to 426 g weekly of emollient cream/ointment) and no overall increase in the use of topical steroids, accounting for potency and quantity used. CONCLUSIONS This study reinforces the importance of specialist dermatology nurses in the management of atopic eczema. It also confirms the opinion of patients, patient support groups, dermatologists and best practice guidelines that the most important intervention in the management of atopic eczema is to spend time to listen and explain its causes and demonstrate how to apply topical therapies.

Abstract
Fatigue has been identified as both a chronic and recurrent problem for individuals diagnosed with and treated for cancer, yet there is little information on how to manage the impact of fatigue. Describing what happens to individuals and their families as a result of fatigue and identifying what individuals do to manage or reduce the impact of fatigue are essential elements in determining multidimensional nursing interventions. The purpose of this pilot study was to examine the impact of fatigue on individuals with cancer of the lung and their families, and explore how they managed as a result of the fatigue. A semi-structured interview guide was used with 22 lung cancer patients and 14 family members six weeks post completion of radiation therapy. Results indicated that fatigue was not reported as a major concern by many of the participants in this study. For those who did experience fatigue, it was considered an inconvenience and a frustration that had to be dealt with for a limited time period. Some patients appeared to gradually adjust and accommodate to the fatigue and were not really aware of the changes that took place over time. Over half of the family members felt more of the impact of fatigue than did their loved ones. Family subtly assumed or took over responsibilities and activities the patient could no longer perform. The symptom of fatigue has been well documented in the cancer experience as both a chronic and recurrent problem for individuals diagnosed with and treated for cancer. The emphasis of previous work has been on deriving a conceptual definition of fatigue, achieving consensus on a definition, and developing theoretical frameworks to guide further study of this complex construct. Fatigue has been conceptualized as a multidimensional phenomenon, attributable to multiple causes and having a negative effect on quality of life (Piper, 1993; Tiesinga, Dasson, & Halfens, 1996). Describing what happens to individuals and their families as a result of fatigue and identifying what individuals do to manage or reduce the effects caused by the fatigue are essential elements in determining multidimensional nursing interventions.
