Implementation of a digital health intervention for young people exposed to Technology Assisted Sexual Abuse.

BACKGROUND: The internet has become a place of increased risk of abuse, including sexual abuse, for young people (YP). One potential risk factor to online abuse and exploitation is the ability to mentalise. We developed the i-Minds app, a mentalisation-based digital health intervention (DHI) for YP who have experienced technology assisted sexual abuse (TASA), which we tested in a clinical feasibility trial. Nested within the trial was a qualitative implementation study with clinicians who referred to the trial. OBJECTIVE: To explore the barriers and enablers to the future integration of i-Minds into clinical practice. PARTICIPANTS AND SETTING: Twelve HCPs were recruited from across two trial recruitment sites (Manchester and Edinburgh). METHODS: Semi-structured interviews were informed by Normalisation Process Theory (NPT). Framework analysis was used; transcripts were coded deductively to NPT constructs. RESULTS: Practitioners were positive about the need for, and added value of, the i-Minds app over existing interventions, including other DHIs. While they felt confident with the app, concerns remained around the safety of using the app without practitioner support. i-Minds promoted changes in practitioners' work and impacted online behaviour of YP. There was an identified need for further training and organisational support. CONCLUSIONS: Practitioners are aware of TASA but have limited knowledge, skills and tools to work with TASA in clinical practice with YP. There is a need for awareness raising and education about TASA and DHI. i-Minds offers a theory-informed DHI for working with YP exposed to TASA that is acceptable to practitioners and YP.

What are practitioners' views of how digital health interventions may play a role in online child sexual abuse service delivery?

Introduction: Online child sexual abuse (OCSA) affects considerable numbers of children globally and is associated with a variety of mental health problems. Existing practitioner studies suggest that young people are infrequently asked about online abuse and practitioners have a fragmented understanding of the problems experienced or how they might approach them. There are very few evidence-based interventions that guide clinical assessment or practice. Digital Health Interventions (DHIs) have the potential to be an effective option where children and young people's services are challenged, including accessibility and anonymity. The aim of this study was to explore mental health practitioners' views of how DHIs may play a role in supporting young people who have experienced OCSA, and the role they can play in healthcare delivery. Method: In-depth qualitative interviews and one focus group were conducted with 25 child mental health professionals across two sites (Manchester and Edinburgh). Data was analyzed using reflexive thematic analysis. Results: Three overarching themes and 9 sub-themes were identified: (1) feeling a little bit lost; (2) seeing potential problems; and (3) knowing what works. Practitioners expressed interest in a DHI to support this client group and saw it as a way of managing waiting lists and complementing existing therapies. They felt that many young people would see this as a preferred medium to in-person therapy, would be empowering, and offers new ways of learning how to stay safe online. However, there were concerns about how much time would be needed by staff to deliver a DHI, anxieties about safety issues in relation to content and data protection, some of which may be unique to this population of young people, and concerns about the absence of a therapeutic relationship with vulnerable children. Discussion: Our findings indicated that practitioners were uncertain about working with children subjected to OCSA but were receptive to the possibility of using a DHI to support their practice and to reduce waiting lists. Concerns were expressed about the time needed for staff training and support as well as concerns over patient safety and the lack of evidence about the effectiveness of an unsupported DHI.

Experiences of a digital health intervention for young people exposed to technology assisted sexual abuse: a qualitative study.

BACKGROUND: There is growing evidence that Technology Assisted Sexual Abuse (TASA) represents a serious problem for large numbers of children. To date, there are very few evidence-based interventions available to young people (YP) after they have been exposed to this form of abuse, and access to support services remains a challenge. Digital tools such as smartphones have the potential to increase access to mental health support and may provide an opportunity for YP to both manage their distress and reduce the possibility of further victimization. The current study explores the acceptability of a digital health intervention (DHI; the i-Minds app) which is a theory-driven, co-produced, mentalization-based DHI designed for YP aged 12-18 who have experienced TASA. METHODS: Semi-structured interviews were conducted with 15 YP recruited through Child and Adolescent Mental Health Services, a Sexual Assault Referral Centre and an e-therapy provider who had access to the i-Minds app as part of a feasibility clinical trial. Interviews focused on the acceptability and usability of i-Minds and were coded to themes based on the Acceptability of Healthcare Interventions framework. RESULTS: All participants found the i-Minds app acceptable. Many aspects of the app were seen as enjoyable and useful in helping YP understand their abuse, manage feelings, and change behavior. The app was seen as usable and easy to navigate, but for some participants the level of text was problematic and aspects of the content was, at times, emotionally distressing at times. CONCLUSIONS: The i-Minds app is useful in the management of TASA and helping change some risk-related vulnerabilities. The app was designed, developed and evaluated with YP who had experienced TASA and this may account for the high levels of acceptability seen. TRIAL REGISTRATION: The trial was registered on the ISRCTN registry on the 12/04/2022 as i-Minds: a digital intervention for young people exposed to online sexual abuse (ISRCTN43130832).

Promoting hEalthy Diet and Active Lifestyle (PEDAL): a protocol for the development and feasibility study of a multicomponent intervention among primary school children in Singapore.

BACKGROUND: Setting healthy lifestyle habits during the formative years of childhood is critical as habits can track to adulthood and help prevent obesity and chronic disease risks in later life. While multicomponent interventions have been shown to be effective in changing the lifestyle behaviours of children, there is a limited understanding of the feasibility of such interventions in primary schools in Singapore. A multiphase mixed method study was conducted to develop and examine the feasibility of a theory-based multicomponent school-based intervention-Promoting hEatlthy Eating and Active Lifestyle (PEDAL). METHODS: Underpinned by Kincaid's ideation model, the PEDAL intervention was developed to increase fruit and vegetable consumption and decrease sedentary behaviours among children. This study consists of three phases. Phase 1 details the development of PEDAL, which consists of four components: (A) a series of interactive health education lessons, (B) actionable home activities to support habit formation, (C) parental/guardian engagement, and (D) optimising the school environment. In Phase 2, components A and B of PEDAL were implemented in two public, co-educational primary schools among Primary 5 students (aged 10-12 years) in Singapore. Data was collected quantitatively using questionnaires and qualitatively using focus group discussions (FGDs) with students and teachers. The feasibility dimensions of components A and B, including recruitment capability, data collection, social validity, and practicality were examined, and ideation on healthy eating and physical activity was explored. In Phase 3, the full PEDAL intervention was pilot-tested in two other public, co-education primary schools with the same target population, using a concurrent mixed method quasi-experimental study design. Feasibility dimensions and potential effectiveness of the intervention will be assessed. DISCUSSION: This study will provide insights into the feasibility of PEDAL and inform its refinement. Findings from the pilot test will guide the planning of a larger-scale definitive trial. TRIAL REGISTRATION: Registered with ISRCTN registry (ISRCTN16114046) on 16 October 2022.

Understanding knowledge, attitudes and behaviours related to dietary sodium intake in a multi-ethnic population in Singapore.

OBJECTIVE: This study aimed to fill the current gap in the understanding of the knowledge, attitudes and behaviours (KAB) related to dietary Na among adult residents in Singapore. DESIGN: A cross-sectional online survey was conducted between October and December 2020 on 955 participants selected through random sampling. SETTING: The survey was conducted in Singapore. PARTICIPANTS: Participants were recruited from the Singapore Population Health Study Online Panel. RESULTS: Participants' mean age was 46·6 ± 14·1 years old and 58 % of them were females. Most of the participants were Chinese (82·1 %), 10·5 % were Indian and 4·5 % were Malay. Findings from the weighted data showed that most participants were aware of the health impact of high Na consumption. However, many participants were unaware of the recommended intake for salt (68%) and Na (83%), had misconceptions, and were unable to correctly use food labels to assess NA content (69%). Findings also alluded to the presence of knowledge gaps in the sources of Na in their diet. While 59 % of the participants reported to be limiting their consumption of Na, many reported facing barriers such as not knowing how to limit their Na intake. Participants also felt that there were limited options for low-Na foods when eating out and were lacking awareness of low-Na products. CONCLUSIONS: Findings highlighted substantial gaps in participants' knowledge and skills in managing their Na consumption. This suggests the need for more public education and improvements in the food environment.

Managing Drug Interactions With Oral Anticancer Treatments.

The use of oral anticancer treatments is widespread and vital to modern cancer treatment. Novel oral chemotherapy and targeted therapy treatments continue to receive US Food and Drug Administration approval every year, making knowledge of these agents a necessity for practitioners working in oncology. Many oral anticancer agents are prone to drug interactions that can contribute to adverse effects and decrease therapy efficacy. Potential drug-drug interactions include (1) interactions with CYP3A4 inhibitors and inducers, (2) interactions related to gastric acid suppression, (3) interactions related to prolongation of the cardiac QT interval, (4) interactions related to anticoagulant medications, and (5) drug-food and drug-herb interactions. Identifying potential drug interactions and appropriately managing them is key to preventing adverse effects and ensuring maximum efficacy while on oral anticancer therapy. Management of adverse effects increases patient compliance, ensures medication safety, and allows patients to remain on therapy. This article discusses the mechanisms of interactions and types of interacting medications. Specific recommendations are discussed.

The experiences of practitioners working with young people exposed to online sexual abuse.

Introduction: This qualitative study explored healthcare professionals' current understanding of, and clinical practices related to, Online Child Sexual Abuse (OCSA). Methods: Data were collected across two UK sites (Manchester and Edinburgh). Interviews and one focus group were held with 25 practitioners working in services offering clinical support to young people who have experienced OCSA. Thematic analysis of the data identified three overarching themes and 10 subthemes related to the research questions: (1) the breadth of the problem; (2) working with OCSA; and (3) the emotionally charged nature of OCSA. Results: While practitioners recognized OCSA as problematic, they differed in how they conceptualized it. There was a heightened awareness of the role that sexual images played in OCSA and concerns about first-person-produced imagery by Children and Young People (CYP). Practitioners described a generational gap related to their technology use and that of the young people they worked with. Practitioners also described a paucity of referral pathways and concerns that there was no training available to them. Organizational barriers meant that questions about technology use were not routinely included in assessments and often there was reliance on young people making disclosures. Discussion: Novel findings from this study were the psychological impacts that such cases had on practitioners, which may indicate a need for organizational support for staff as well as further training needs. Existing frameworks that help conceptualize and assess the role of technology as part of the ecology of the child may have great utility for practitioners.

Understanding agoraphobic avoidance: the development of the Oxford Cognitions and Defences Questionnaire (O-CDQ).

BACKGROUND: Many patients with mental health disorders become increasingly isolated at home due to anxiety about going outside. A cognitive perspective on this difficulty is that threat cognitions lead to the safety-seeking behavioural response of agoraphobic avoidance. AIMS: We sought to develop a brief questionnaire, suitable for research and clinical practice, to assess a wide range of cognitions likely to lead to agoraphobic avoidance. We also included two additional subscales assessing two types of safety-seeking defensive responses: anxious avoidance and within-situation safety behaviours. METHOD: 198 patients with psychosis and agoraphobic avoidance and 1947 non-clinical individuals completed the item pool and measures of agoraphobic avoidance, generalised anxiety, social anxiety, depression and paranoia. Factor analyses were used to derive the Oxford Cognitions and Defences Questionnaire (O-CDQ). RESULTS: The O-CDQ consists of three subscales: threat cognitions (14 items), anxious avoidance (11 items), and within-situation safety behaviours (8 items). Separate confirmatory factor analyses demonstrated a good model fit for all subscales. The cognitions subscale was significantly associated with agoraphobic avoidance (r = .672, p < .001), social anxiety (r = .617, p < .001), generalized anxiety (r = .746, p < .001), depression (r = .619, p < .001) and paranoia (r = .655, p < .001). Additionally, both the O-CDQ avoidance (r = .867, p < .001) and within-situation safety behaviours (r = .757, p < .001) subscales were highly correlated with agoraphobic avoidance. The O-CDQ demonstrated excellent internal consistency (cognitions Cronbach's alpha = .93, avoidance Cronbach's alpha = .94, within-situation Cronbach's alpha = .93) and test-re-test reliability (cognitions ICC = 0.88, avoidance ICC = 0.92, within-situation ICC = 0.89). CONCLUSIONS: The O-CDQ, consisting of three separate scales, has excellent psychometric properties and may prove a helpful tool for understanding agoraphobic avoidance across mental health disorders.

Rapid High-Yield Production of Functional SARS-CoV-2 Receptor Binding Domain by Viral and Non-Viral Transient Expression for Pre-Clinical Evaluation.

Vaccine design strategies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are focused on the Spike protein or its subunits as the main antigen target of neutralizing antibodies. In this work, we propose rapid production methods of an extended segment of the Spike Receptor Binding Domain (RBD) in HEK293SF cells cultured in suspension, in serum-free media, as a major component of a COVID-19 subunit vaccine under development. The expression of RBD, engineered with a sortase-recognition motif for protein-based carrier coupling, was achieved at high yields by plasmid transient transfection or human type-5-adenoviral infection of the cells, in a period of only two and three weeks, respectively. Both production methods were evaluated in 3L-controlled bioreactors with upstream and downstream bioprocess improvements, resulting in a product recovery with over 95% purity. Adenoviral infection led to over 100 µg/mL of RBD in culture supernatants, which was around 7-fold higher than levels obtained in transfected cultures. The monosaccharide and sialic acid content was similar in the RBD protein from the two production approaches. It also exhibited a proper conformational structure as recognized by monoclonal antibodies directed against key native Spike epitopes. Efficient direct binding to ACE2 was also demonstrated at similar levels in RBD obtained from both methods and from different production lots. Overall, we provide bioprocess-related data for the rapid, scalable manufacturing of low cost RBD based vaccines against SARS-CoV-2, with the added value of making a functional antigen available to support further research on uncovering mechanisms of virus binding and entry as well as screening for potential COVID-19 therapeutics.

Tracking the Effects of Ligands on Oxidative Etching of Gold Nanorods in Graphene Liquid Cell Electron Microscopy.

Surface ligands impact the properties and chemistry of nanocrystals, but observing ligand binding locations and their effect on nanocrystal shape transformations is challenging. Using graphene liquid cell electron microscopy and the controllable, oxidative etching of gold nanocrystals, the effect of different ligands on nanocrystal etching can be tracked with nanometer spatial resolution. The chemical environment of liquids irradiated with high-energy electrons is complex and potentially harsh, yet it is possible to observe clear evidence for differential binding properties of specific ligands to the nanorods' surface. Exchanging CTAB ligands for PEG-alkanethiol ligands causes the nanorods to etch at a different, constant rate while still maintaining their aspect ratio. Adding cysteine ligands that bind preferentially to nanorod tips induces etching predominantly on the sides of the rods. This etching at the sides leads to Rayleigh instabilities and eventually breaks apart the nanorod into two separate nanoparticles. The shape transformation is controlled by the interplay between atom removal and diffusion of surface atoms and ligands. These in situ observations are confirmed with ex situ colloidal etching reactions of gold nanorods in solution. The ability to monitor the effect of ligands on nanocrystal shape transformations will enable future in situ studies of nanocrystals surfaces and ligand binding positions.

Evaluation of adenomyosis after gonadotrophin-releasing hormone agonist therapy using ultrasound post-processing imaging: a pilot study.

OBJECTIVE: We explored a method for the quantitative sonographic analysis of myometrial texture using computer-aided image analysis software to assess outcomes following treatment with gonadotrophin-releasing hormone (GnRH) agonist for adenomyosis in women with infertility. METHOD: Data for patients with ultrasound images of the myometrium obtained at Taipei Medical University Hospital from 1 September 2018 to 5 April 5 2019 were analyzed. Only 10 patients with 20 ultrasound images matched the eligibility criteria. The images were divided into pre-treatment (n = 10) and post-treatment images (n = 10) and quantitative grayscale histograms were obtained from the ultrasound images using publicly available ImageJ computer-aided image analysis software. We analyzed the differences between the pre- and post-treatment images using the Mann-Whitney test and compared the results with outcomes assessed by serum CA-125 levels. RESULTS: Image analysis of the grayscale histograms revealed significant differences between before and after treatment. The classification of the myometrium pre-treatment and post-treatment was similar using CA-125 and histogram grayscale analysis. CONCLUSION: Computer-aided image analysis of grayscale histograms of the myometrium obtained from ultrasound images is an alternative method for assessing myometrial conditions after GnRH agonist treatment in patients with adenomyosis.

Live birth in male de novo Kallmann syndrome after cross-generational genetic sequencing.

PURPOSE: To present the first case proposing the use of preimplantation genetic testing for monogeneic disorders for Kallmann syndrome, providing comprehensive care in the genomic era of precision medicine. METHODS: Gonadotropin therapy was used for spermatogenesis, followed by in vitro fertilization by intracytoplasmic sperm injection and embryo transfer. Cross-generational targeted next-generation sequencing was then done for genes known to cause Kallmann syndrome. RESULTS: A heterozygous mutation at codon 102 of the FGFR1 gene was found in the patient, but the father was found to have the same mutation yet is unaffected by Kallmann syndrome. Since no causative mutation was found, a de novo or sporadic mutation was suspected as the cause of Kallmann syndrome in this case. CONCLUSIONS: Comprehensive care must be available for male Kallmann syndrome patients, as treatment should not stop at spermatogenesis, but continue with genetic counseling due to possible inheritance.

Do distance-delivery group interventions improve depression in people with epilepsy?

About one-third of people with epilepsy experience comorbid depression. The present study examined outcomes of a distance-delivery group intervention program designed to improve emotional well-being. Participants were 55 adults with epilepsy and self-reported depressive symptoms who were randomly assigned to take part in either a mindfulness-based cognitive behavioral therapy (CBT) program (UPLIFT, n = 20), an epilepsy information and self-management program (EpINFO, n = 24) that served as an active control group, or a wait-list control (WLC) group (n = 11). The Quick Inventory of Depressive Symptomatology (QIDS), Neurological Disorders Depression Inventory for Epilepsy (NDDIE), and the psychological health subscale of the World Health Organization Quality of Life (WHOQOL-BREF) scale were used to assess depression and psychological quality of life before and after treatment, and at short-term (six months) and long-term follow-up (one year) upon program completion. From pre- to posttreatment, a main effect of time was found, with participants in both the UPLIFT and EpINFO groups having reported to a similar degree a significant decrease in depressive symptoms and improved psychological health, improvements that were not seen in the WLC group. The time by group interaction effect was not significant. The effects seen at posttreatment in the UPLIFT and EpINFO groups remained at six months and one year after treatment. These data suggest that distance-delivery group intervention programs are effective at improving depression and psychological quality of life, with the EpINFO program offering benefits similar to the UPLIFT program.

Gold Nanocrystal Etching as a Means of Probing the Dynamic Chemical Environment in Graphene Liquid Cell Electron Microscopy.

Graphene liquid cell electron microscopy has the necessary temporal and spatial resolution to enable the in situ observation of nanoscale dynamics in solution. However, the chemistry of the solution in the liquid cell during imaging is as yet poorly understood due to the generation of a complex mixture of radiolysis products by the electron beam. In this work, the etching trajectories of nanocrystals were used as a probe to determine the effect of the electron beam dose rate and preloaded etchant, FeCl3, on the chemistry of the liquid cell. Initially, illuminating the sample at a low electron beam dose rate generates hydrogen bubbles, providing a reservoir of sacrificial reductant. Increasing the electron beam dose rate leads to a constant etching rate that varies linearly with the electron beam dose rate. Comparing these results with the oxidation potentials of the species in solution, the electron beam likely controls the total concentration of oxidative species in solution and FeCl3 likely controls the relative ratio of oxidative species, independently determining the etching rate and chemical potential of the reaction, respectively. Correlating these liquid cell etching results with the ex situ oxidative etching of gold nanocrystals using FeCl3 provides further insight into the liquid cell chemistry while corroborating the liquid cell dynamics with ex situ synthetic behavior. This understanding of the chemistry in the liquid cell will allow researchers to better control the liquid cell electron microscopy environment, allowing new nanoscale materials science experiments to be conducted systematically in a reproducible manner.

Emergence of a Competence-Reducing Filamentous Phage from the Genome of Acinetobacter baylyi ADP1.

Bacterial genomes commonly contain prophage sequences as a result of past infections with lysogenic phages. Many of these integrated viral sequences are believed to be cryptic, but prophage genes are sometimes coopted by the host, and some prophages may be reactivated to form infectious particles when cells are stressed or mutate. We found that a previously uncharacterized filamentous phage emerged from the genome of Acinetobacter baylyi ADP1 during a laboratory evolution experiment. This phage has a genetic organization similar to that of the Vibrio cholerae CTXϕ phage. The emergence of the ADP1 phage was associated with the evolution of reduced transformability in our experimental populations, so we named it the competence-reducing acinetobacter phage (CRAϕ). Knocking out ADP1 genes required for competence leads to resistance to CRAϕ infection. Although filamentous bacteriophages are known to target type IV pili, this is the first report of a phage that apparently uses a competence pilus as a receptor. A. baylyi may be especially susceptible to this route of infection because every cell is competent during normal growth, whereas competence is induced only under certain environmental conditions or in a subpopulation of cells in other bacterial species. It is possible that CRAϕ-like phages restrict horizontal gene transfer in nature by inhibiting the growth of naturally transformable strains. We also found that prophages with homology to CRAϕ exist in several strains of Acinetobacter baumannii These CRAϕ-like A. baumannii prophages encode toxins similar to CTXϕ that might contribute to the virulence of this opportunistic multidrug-resistant pathogen. IMPORTANCE: We observed the emergence of a novel filamentous phage (CRAϕ) from the genome of Acinetobacter baylyi ADP1 during a long-term laboratory evolution experiment. CRAϕ is the first bacteriophage reported to require the molecular machinery involved in the uptake of environmental DNA for infection. Reactivation and evolution of CRAϕ reduced the potential for horizontal transfer of genes via natural transformation in our experiment. Risk of infection by similar phages may limit the expression and maintenance of bacterial competence in nature. The closest studied relative of CRAϕ is the Vibrio cholerae CTXϕ phage. Variants of CRAϕ are found in the genomes of Acinetobacter baumannii strains, and it is possible that phage-encoded toxins contribute to the virulence of this opportunistic multidrug-resistant pathogen.

Comparison of robotic approach, laparoscopic approach and laparotomy in treating epithelial ovarian cancer.

BACKGROUND: The purpose of this study was to evaluate the feasibility of robotic surgery and compare its surgical outcomes with those of laparoscopic surgery and laparotomy, with regard to performing staging surgery to manage ovarian cancer. METHODS: One hundred and thirty-eight women who received surgical staging procedures for treatment of stage IA-IIIC epithelial ovarian cancer and borderline tumours were retrospectively included in the study. All enrolled cases were reviewed for patient demographics, peri-operative parameters, complications and survival. RESULTS: The operation time and blood loss was significantly reduced in the robotic and laparoscopic groups. Moreover, robotic surgery was associated with decreased postoperative pain score. The length of hospital stay and time to full diet resumption were also shortened for those who underwent robotic and laparoscopic procedures. Survival analysis and complication rates were similar between the two groups. CONCLUSION: Robotic surgery is a feasible alternative in managing ovarian cancer as long as there is careful consideration given to patient selection. Copyright © 2015 John Wiley & Sons, Ltd.

Global assessment of the severity of epilepsy (GASE) Scale in children: Validity, reliability, responsiveness.

OBJECTIVE: The Global Assessment of Severity of Epilepsy (GASE) Scale is a single-item, 7-point global rating scale designed for neurologist-report of overall severity of epilepsy in children. Building on previous preliminary evidence of its validity and reliability for research and clinical use, this study evaluated the GASE Scale's construct validity, reliability, and responsiveness to changes in severity of epilepsy. METHODS: Data used for the study arose from the Health-Related Quality of Life in Children with Epilepsy Study (HERQULES), a 2-year multicenter prospective cohort study (n = 374) with observations taken at baseline, and 6, 12, and 24 months after diagnosis. Construct validity and reliability were quantified using Spearman's correlation and intraclass correlation coefficient (ICC). Responsiveness was assessed using both distribution-based and anchor-based indices. RESULTS: The GASE Scale was at least moderately correlated (r ≥ 0.30) with several key clinical aspects and most strongly correlated with frequency and intensity of seizures and interference of epilepsy or drugs with daily activities (r > 0.30). Total variation in GASE Scale scores explained by seven core clinical aspects of epilepsy increased over time (R(2) = 28% at baseline to R(2) = 70% at 24 months). The GASE Scale had modest test-retest reliability (ICC range: 0.52-0.64) and was responsive to changes in clinical criteria (standardized response mean range: 0.49-0.68; probability of change range: 0.69-0.75; Guyatt's responsiveness statistic range: 0.56-0.84). The GASE Scale showed potential to discriminate "stable" and "changed" patients according to select criteria and to a composite score (area under the receiver operating characteristic [ROC] curve range: 0.50-0.67). SIGNIFICANCE: Results offer additional evidence in support of the GASE Scale's validity, reliability, as well as responsiveness to changes in severity of epilepsy in children. We conclude that the GASE Scale is a potentially useful tool for assessing the severity of epilepsy in both clinical and research settings.

Management of ovarian cancer in 14th gestational week of pregnancy by robotic approach with preservation of the fetus.

The objective of this study is to present a rare case of pregnancy complicated with ovarian cancer managed by robotic surgery. A 36-year-old woman suffered from sudden onset of lower abdominal pain during her pregnancy at 14 weeks of gestation. As malignancy was highly suspected, left salpingo-oophorectomy, bilateral pelvic lymph node dissection, and omentectomy were performed by robotic approach. The uterus and fetus were preserved. After surgery, 5 courses of carboplatin and paclitaxel were given, and the patient was delivered by cesarean section at 37 weeks of pregnancy. Follow-up at 18 months showed no signs of cancer recurrence. As there is limited report of pregnancy complicated with ovarian cancer managed by robotic surgery, we provide this rare case and suggest that surgical staging for ovarian malignancy can be safely accomplished by robotic approach at 14 weeks of pregnancy.

Parallel walk test: its correlation with balance and motor functions in people with chronic stroke.

OBJECTIVES: To investigate (1) the intrarater, interrater, and test-retest reliability of the times and scores generated in the parallel walk test (PWT); (2) their correlations with impairments and activity limitations of individuals with stroke; and (3) the cutoff times that best discriminate individuals with stroke from healthy elderly subjects. DESIGN: Cross sectional study. SETTING: University-based rehabilitation center. PARTICIPANTS: Participants (N=72) comprised individuals with stroke (n=37) and healthy individuals (n=35). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The PWT was administered along with the Fugl-Meyer Motor Assessment of the Lower Extremities (FMA-LE), handheld dynamometer measurements of ankle dorsiflexor and plantarflexor muscle strength, the 5-Times-Sit-to-Stand Test, the Berg Balance Scale (BBS), a limits of stability (LOS) test, the 10-m walk test (10-MWT), and the timed Up and Go (TUG) test. RESULTS: PWT times and scores showed good to excellent intrarater, interrater, and test-retest reliability in individuals with stroke. PWT times using paths of 3 different widths significantly correlated with FMA-LE scores, 5-Times-Sit-to-Stand Test times, BBS scores, some LOS test results, 10-MWT gait speed, and TUG test times. PWT times of 6.30 to 7.48 seconds, depending on the path width, were shown reliably to discriminate individuals with stroke from healthy individuals. CONCLUSION: The PWT is a reliable, easy-to-administer clinical tool for assessing dynamic walking balance in individuals with chronic stroke.
