    Abstract Mitral valve prolapse (MVP) is a common and predominantly benign condition; however, occasional reports of cardiac arrest in individuals with MVP have raised concern for a malignant subtype. The risk of sudden cardiac arrest in MVP is twice as high as that in the general population. The exact aetiology and risk predictors are elusive, but identification is necessary, if we are to protect patients at risk for cardiac arrest. This report highlights cardiac arrest as the initial presenting symptom of MVP. Rapid initiation of bystander cardiopulmonary resuscitation and time to first shock are key predictors of prognosis. Better screening to identify individuals with malignant phenotypes may aid in reducing the morbidity and mortality in patients with a predisposition for life-threatening arrhythmias.

    Abstract A 17-year-old African-American man was being followed for palpitations and chest pain. CT angiography revealed an anomalous right coronary artery from the left coronary sinus and he underwent unroofing of the right coronary ostium. There was a manifest pre-excitation on postoperative ECGs, and review of prior ECGs at initial presentation showed subtle pre-excitation suggesting a left lateral pathway. An electrophysiology study revealed easily inducible supraventricular tachycardia (SVT) and rapid anterograde conduction via the pathway which was successfully ablated. Eight months postablation, the patient remains asymptomatic with no evidence of pre-excitation on ECG.

  3. Book ; Online: A comparative study of collections from the S.W. Pacific (Saipan to Tonga), with the descriptions of Gambiella caudata (Brady, 1890) and a new species of Pterobairdia (Ostracoda)

    Abstract: Gambiella caudata (Brady, 1890) and Pterobairdia briggsae sp. nov. are described from collections made in the S. W. Pacific (Saipan, Onotoa, Ontong-Java/Kula Gulf, Noumea, Cook Islands, Fiji, Samoa, Tonga); and the lectotypes of several species described ...

    Abstract Gambiella caudata (Brady, 1890) and Pterobairdia briggsae sp. nov. are described from collections made in the S. W. Pacific (Saipan, Onotoa, Ontong-Java/Kula Gulf, Noumea, Cook Islands, Fiji, Samoa, Tonga); and the lectotypes of several species described in a major early paper by Brady (1890) are illustrated. The carbonate compensation depth in this region lies at around 4500 m. Comparison of the Ontong-Java in Kula Gulf samples reinforces consideration of depth as a factor of ecological importance. A similarity matrix for the several faunas shows factors in common at species level ranging from 22% (Onotoa/Noumea) to nearly 60% (Samoa/Onotoa); while endemism ranges from 8.5% (Samoa) to nearly 33% (Tonga). Most endemic species belong in a limited number of podocopid families, in particular Bairdiidae, Trachyleberididae, Paradoxostomatidae and Leptocytheridae. These results appear consistent with an hypothesis that continued tectonics-driven changes in the regional marine topography and sedimentation, i.e. niche development, could have triggered speciation along the regional plate margins.

    Abstract Background: Transition from prison to community is a challenging time for all people who have been incarcerated. It is particularly challenging for those also living with serious and persistent mental illness. This study explored staff experiences and perspectives of what helped and hindered them in their work to support that transition.
    Methods: Semi-structured interviews were conducted with 12 mental health staff working across three service sectors directly engaged in the process of supporting people with mental illness transitioning from prison to community; the forensic mental health provider Justice Health, Community Mental Health and a non-government delivered community-based service called Partners in Recovery. Data were analysed using constant comparative analysis.
    Results: Five main themes were identified through the analysis. All five themes were key practices that, when occurring, supported staff to work in a way that they felt would maximise positive outcomes for people transitioning from prison to community. These included: housing secured before release; clearly defined and effective communication pathways; shared understanding of systems and roles; in-reach and continuity of contact, and consumers' pre-release preparation and knowledge. All staff participants described barriers to good transition to community outcomes when some or all of these practices could not, or did not, occur.
    Conclusions: Staff experiences highlight the complexity but importance of getting multi-sectorial partnerships and practices right for good prison to community transitions for people living with serious and persistent mental illness. Currently fragmented and disparate systems and practices need to align and clear expectations and understandings need to be shared across the whole. These changes, along with prioritised housing are likely to lead to better long-term outcomes for people.

    Abstract The next generation of Gravity Recovery and Climate Experiment (GRACE)-like dual-satellite geodesy missions proposals will rely on inter-spacecraft laser interferometry as the primary instrument to recover geodesy signals. Laser frequency stability is one of the main limits of this measurement and is important at two distinct timescales: short timescales over 10-1000 seconds to measure the local gravity below the satellites, and at the month to year timescales, where the subsequent gravity measurements are compared to indicate loss or gain of mass (or water and ice) over that period. This paper demonstrates a simple phase modulation scheme to directly measure laser frequency change over long timescales by comparing an on-board Ultra-Stable Oscillator (USO) clocked frequency reference to the Free Spectral Range (FSR) of the on-board optical cavity. By recording the fractional frequency variations the scale correction factor may be computed for a laser locked to a known longitudinal mode of the optical cavity. The experimental results demonstrate a fractional absolute laser frequency stability at the 10 ppb level (10

    Title translation Étude qualitative des mesures incitatives et de dissuasion dans les équipes Santé familiale ontariennes pour les soins pour les troubles mentaux les plus courants.
    Abstract Background: An opportunity to address the needs of patients with common mental disorders (CMDs) resides in primary care. Barriers are restricting availability of treatment for CMDs in primary care. By understanding the incentives that promote and the disincentives that deter treatment for CMDs in a collaborative primary care context, this study aims to help contribute to goals of greater access to mental healthcare.
    Method: A qualitative pilot study using semi-structured interviews with thematic analysis.
    Results: Participants identified 10 themes of incentives and disincentives influencing quality treatment of CMDs in a collaborative primary care setting: high service demands, clinical presentation, patient-centred care, patient attributes, education, physician attributes, organizational, access to mental health resources, psychiatry and physician payment model.
    Conclusion: An understanding of the incentives and disincentives influencing care is essential to achieve greater integration and capacity for care for the treatment of CMDs in primary care.

    Abstract Objective: There is widespread support for primary care to help address growing mental health care demands. Incentives and disincentives are widely used in the design of health care systems to help steer toward desired goals. The absence of a conceptual model to help understand the range of factors that influence the provision of primary mental health care inspired a scoping review of the literature. Understanding the incentives that promote and the disincentives that deter treatment for depression and anxiety in the primary care context will help to achieve goals of greater access to mental health care.
    Method: A review of the literature was conducted to answer the question, how are incentives and disincentives conceptualized in studies investigating the treatment of common mental disorders in primary care? A comprehensive search of MEDLINE, PsycINFO, CINAHL, and Google Scholar was undertaken using Arksey and O'Malley's 5-stage methodological framework for scoping reviews.
    Results: We identified 27 studies. A range of incentives and disincentives influence the success of primary mental health care initiatives to treat depression and anxiety. Six types of incentives and disincentives can encourage or discourage treatment of depression and anxiety in primary care: attitudes and beliefs, training and core competencies, leadership, organizational, financial, and systemic.
    Conclusions: Understanding that there are 6 different types of incentives that influence treatment for anxiety and depression in primary care may help service planners who are trying to promote improved mental health care.

    Abstract Bed bugs, Cimex lectularius L., feed on humans, have increased exponentially in the past two decades in many major cities throughout the world, have caused intense infestations, and have become a significant health concern. Improved traps are needed to detect early infestations, to assess control programs, and for control of bed bugs. Carbon dioxide released alone or simultaneously with other attractants into three types of traps at the relatively low rate of 1 ml/min caught significantly more bed bugs than untreated controls in a 183- by 183-cm arena. This finding may enable CO2 to be used more economically in traps. Three percent ammonium bicarbonate released at a rate of ≤0.03 ml/h also caught significantly more bed bugs than untreated controls. A blend of (E)-2-hexenal and (E)-2-octenal at concentrations of 0.025% or 0.1% each and released at 0.02 ml/h attracted significantly more bed bugs than untreated controls. These findings ought to improve detection of bed bugs.

    Abstract Aim: To develop a consensus framework to evaluate the impact of screening for intellectual disability, using the Child and Adolescent Intellectual Disability Screening Questionnaire (CAIDS-Q) in paediatric neurodevelopment clinics.
    Method: A modified Delphi survey with four phases (literature review; initial development of framework [participants=11 parents, 8 professionals]; qualitative interviews [participants=4 parents, 15 professionals]; questionnaire development [participants=31 parents, 14 professionals] was used to develop the consensus framework. The framework was used to evaluate the impact of screening on six paediatricians and 31 parents of children who had participated in a previous paediatric screening project.
    Results: Twelve of the original 20 items were retained based on levels of endorsement of 60 per cent or above. Direct benefits of using the CAIDS-Q were: indicating the child's level of functioning, increasing awareness of intellectual disability, helping to identify children with intellectual disability, and identifying potentially vulnerable children. Benefits related to subsequent diagnostic assessment were: promoting greater understanding of the child, identification of support needs, and receipt of support, particularly for the child at school.
    Interpretation: The use of the CAIDS-Q had a number of direct and indirect benefits for children, families, and services as reported by parents and paediatricians.
    What this paper adds: A 12-item framework was developed to evaluate the impact of screening for intellectual disability. Direct benefits of the Child and Adolescent Intellectual Disability Screening Questionnaire include increasing awareness and identification of intellectual disability. Indirect benefits included increased identification of support needs and receipt of support.

    Abstract Aim: This paper aims at documenting the process of implementing "Kenya Integrated intervention model for Dialogue and Screening to promote children's mental wellbeing (KIDS)", with emphasis on activities, experiences, challenges and lessons learnt through the process that can inform improvement in Kenya and other social-economically and culturally similar settings.
    Methods: KIDS aimed at providing early and integrated culturally acceptable intervention to promote child mental health in 6 to 13 year olds, targeting 5429 children in 24 schools. It was a pilot study conducted in 2 administrative counties in Kenya (Machakos and Makueni). The main goal of this study was to test the efficacy and feasibility of the proposed model that incorporated several significant stakeholders.
    Results: The implementation of KIDS was grouped into 6 stepwise and 2 ongoing processes: (1) Stakeholder engagement and collaboration; (2) Selecting, adapting, translating, piloting and adopting the study tools; (3) Conducting Participatory Theory of Change (ToC); (4) Building the capacity of the key implementing partners; (5) Community awareness and psycho-education, (6) Using school-based life skills and peer clubs counselling to provide psychosocial support; (7) Ongoing monitoring, supervision and quality assurance and (8) Ongoing knowledge exchange and dissemination. Specific logistical challenges and possible solutions for future school mental health services are also stated in this article.
    Conclusion: KIDS is a feasible model for school mental health service programme in Kenya but there are challenges which provide innovative opportunities for better designed school mental health services programme.
