Ebola virus disease epidemic in West Africa: Lessons learned and issues arising from West African countries

© Royal College of Physicians 2015. All rights reserved.The current Ebola virus disease (EVD) outbreak ravaging three nations in West Africa has affected more than 14,000 persons and killed over 5,000. It is the longest and most widely spread Ebola epidemic ever seen. At the time of this overview (written November 2014), having affected eight different nations, Nigeria and Senegal were able to control and eliminate the virus within a record time. Ghana has successfully, to date, kept the virus away from the country, despite economic and social relationships with affected nations. What lessons can we learn from Nigeria, Senegal and Ghana in the current epidemic? How can the world improve the health systems in low- and middle-income countries to effectively manage future outbreaks? Recently, the Royal College of Physicians launched a new partnership with the West African College of Physicians to curtail the effects of HIV/AIDS, malaria and tuberculosis in the region. We believe that strengthened health systems, skilled human resources for health and national ownership of problems are key to effective management of outbreaks such as EVD

Experiences of parent-infant teams among mothers diagnosed with perinatal mental health difficulties

Background: Disrupted parent-infant bonds can have a negative impact on childhood development. In the United Kingdom, parent-infant teams can offer support to parents (most commonly mothers) to help strengthen parent-infant relationships. However, little is known about women’s experiences of these teams. This study aimed to explore experiences of support from parent-infant teams among mothers diagnosed with perinatal mental health difficulties. Method: Qualitative semi-structured interviews were conducted with eleven mothers who had had been referred to and/or accessed a National Health Service parent-infant team. Interviews were analysed using thematic analysis. Results: Women reported occasional difficulties accessing parent-infant services, particularly when they were left to contact services/follow up referrals themselves. However, once accessed mothers valued consistent, regular support with a therapist who was empathic and accepting of their difficult feelings. Some women saw therapists as resembling ‘mother figures’ and appreciated a feeling of being cared for. However, at times women felt there was an overemphasis on the role of the mother and mother-infant bond, and a disregard of fathers and other family members. Conclusion: Our study demonstrates that mothers value support from parent-infant teams. However, clinicians need to ensure they do not inadvertently reinforce problematic gender norms and narratives when offering support

Experiences of Improving Access to Psychological Therapy Services for Perinatal Mental Health Difficulties: a Qualitative Study of Women's and Therapists' Views

BACKGROUND: Perinatal mental health difficulties are highly prevalent. In England, the Improving Access to Psychological Therapy (IAPT) programme provides evidence-based psychological treatment, predominantly in the form of brief manualized cognitive behavioural therapy (CBT), to people with mild to moderate depression or anxiety. Yet little is known about the experiences of women referred to IAPT with perinatal mental health difficulties. AIMS: The aim of this qualitative study was to investigate how women view IAPT support for perinatal mental health. We also gained the perspective of IAPT therapists. METHOD: Semi-structured interviews were conducted with twelve women who had been referred to and/or received therapy from IAPT during the perinatal period. Additionally, fourteen IAPT therapists participated in two focus groups. Thematic analysis was used. RESULTS: Key themes centred on barriers to access and the need to tailor support to (expectant) mothers. Women and therapists suggested that experiences could be improved by supporting healthcare professionals to provide women with more help with referrals, better tailoring support to the perinatal context, improving perinatal-specific training, supervision and resources, and offering a more individualized treatment environment. CONCLUSIONS: Overall, women reported positive experiences of support offered by IAPT for perinatal mental health difficulties. However, services should seek to facilitate access to support and to enable therapists to better tailor treatment

Supraspinal fatigue in human inspiratory muscles with repeated sustained maximal efforts

To investigate the involvement of supraspinal fatigue in the loss of maximal inspiratory pressure (PImax), we fatigued the inspiratory muscles. Six participants performed 5 sustained maximal isometric inspiratory efforts (15-s contractions, duty cycle ~75%) which reduced PImax, as measured from esophageal and mouth pressure, to around half of their initial maximums. Transcranial magnetic stimulation (TMS) delivered over the motor cortex near the beginning and end of each maximal effort evoked superimposed twitch-like increments in the ongoing PImax, increasing from ~1.0% of PImax in the unfatigued contractions to ≥40% of ongoing PImax for esophageal and mouth pressures. The rate of increase in the superimposed twitch as PImax decreased with fatigue was not significantly different between the esophageal and mouth pressure measures. The inverse relationship between superimposed twitch pressure and PImax indicates a progressive decline in the ability of motor cortical output to drive the inspiratory muscles maximally, leading to the development of supraspinal fatigue. TMS also evoked silent periods in the electromyographic recordings of diaphragm, scalenes, and parasternal intercostal. The duration of the silent period increased with fatigue in all three muscles, which suggests greater intracortical inhibition, with the largest change observed in the diaphragm. The peak rate of relaxation in pressure during the silent period slowed as fatigue developed, indicating peripheral contractile changes in the active inspiratory muscles. These changes in the markers of fatigue show that both central and peripheral fatigue contribute to the loss in PImax when inspiratory muscles are fatigued with repeated sustained maximal efforts. NEW & NOTEWORTHY When the inspiratory muscles are fatigued with repeated sustained maximal efforts, supraspinal fatigue, a component of central fatigue, contributes to the loss in maximal inspiratory pressure. The presence of supraspinal fatigue was confirmed by the increase in amplitude of twitch-like increments in pressure evoked by motor cortical stimulation during maximal efforts, indicating that motor cortical output was not maximal as extra muscle force could be generated to increase inspiratory pressure

Psychosocial stress and strategies for managing adversity: measuring population resilience in New South Wales, Australia

<p>Abstract</p> <p>Background</p> <p>Populations around the world are facing an increasing number of adversities such as the global financial crisis, terrorism, conflict, and climate change. The aim of this paper was to investigate self-reported strategies and sources of support used to get through "tough times" in an Australian context and to identify patterns of response in the general population and differences in potentially vulnerable subgroups.</p> <p>Methods</p> <p>Data were collected through a cross-sectional survey of the New South Wales population in Australia. The final sample consisted of 3,995 New South Wales residents aged 16 years and above who responded to the question: "What are the things that get you through tough times?"</p> <p>Results</p> <p>Respondents provided brief comments that were coded into 14 main subject-area categories. The most frequently reported responses were family and self (52%); friends and neighbors (21%); use of positive emotional and philosophical strategies (17%), such as sense of humor, determination, and the belief that things would get better; and religious beliefs (11%). The responses of four population subgroups were compared, based on gender, household income, level of psychological distress, and whether a language other than English was spoken at home. Women reported greater use of friends and neighbors and religious or spiritual beliefs for support, whereas men reported greater use of drinking/smoking and financial supports. Those with lower incomes reported greater reliance on positive emotional and philosophical strategies and on religious or spiritual beliefs. Those with high levels of psychological distress reported greater use of leisure interests and hobbies, drinking/smoking, and less use of positive lifestyle strategies, such as adequate sleep, relaxation, or work/life balance. Those who spoke a language other than English at home were less likely to report relying on self or others (family/friends) or positive emotional and philosophical strategies to get through tough times.</p> <p>Conclusions</p> <p>Understanding strategies and sources of support used by the population to get through adversity is the first step toward identifying the best approaches to build and support strengths and reduce vulnerabilities. It is also possible to reflect on how large-scale threats such as pandemics, disasters, conflict, bereavement, and loss could impact individual and population resilience.</p

Behavioral response of dissimilatory perchlorate-reducing bacteria to different electron acceptors

The response behavior of three dissimilatory perchlorate-reducing bacteria to different electron acceptors (nitrate, chlorate, and perchlorate) was investigated with two different assays. The observed response was species-specific, dependent on the prior growth conditions, and was inhibited by oxygen. We observed attraction toward nitrate when Dechloromonas aromatica strain RCB and Azospira suillum strain PS were grown with nitrate. When D. aromatica and Dechloromonas agitata strain CKB were grown with perchlorate, both responded to nitrate, chlorate, and perchlorate. When A. suillum was grown with perchlorate, the organism responded to chlorate and perchlorate but not nitrate. A gene replacement mutant in the perchlorate reductase subunit (pcrA) of D. aromatica resulted in a loss of the attraction response toward perchlorate but had no impact on the nitrate response. Washed-cell suspension studies revealed that the perchlorate grown cells of D. aromatica reduced both perchlorate and nitrate, while A. suillum cells reduced perchlorate only. Based on these observations, energy taxis was proposed as the underlying mechanism for the responses to (per)chlorate by D. aromatica. To the best of our knowledge, this study represents the first investigation of the response behavior of perchlorate-reducing bacteria to environmental stimuli. It clearly demonstrates attraction toward chlorine oxyanions and the unique ability of these organisms to distinguish structurally analogous compounds, nitrate, chlorate, and perchlorate and respond accordingly

"Am iz kwiin" (I'm his queen): Combining interpretative phenomenological analysis with a feminist approach to work with gems in a resource-constrained setting

This article focuses on working with gems using a feminist approach to interpretative phenomenological analysis (IPA) in a resource-constrained setting. The research explores the experiences of maternal disclosure of HIV to children of HIV positive mothers in Kingston, Jamaica. A feminist approach helps recognise power imbalances within research relationships and the women’s lived experiences. We present three “gems” which illuminate women’s lived experiences and explore how popularised representations of women’s sexuality and mothering influence disclosure discourses. We use emotion work as a conceptual resource to structure the women’s narratives and challenge existing policy discourses, which arguably represent disclosure within a binary, rationalist, decision-making framework. This article adds to global literature on maternal HIV disclosure and problematises policy discourses by bringing into relief the emotion work women engage in when deciding if and how to communicate their HIV status to their children. It adds to the body of research using IPA, particularly in resource-constrained settings where IPA has thus far had little application
