RESUMEN

OBJECTIVE: To explore midwives' skills, knowledge and experiences of supporting women's mental health. RESEARCH DESIGN AND SETTING: This paper reports the second phase of a larger project, the 'Mothers' Mood Study', which recruited women and midwives to explore their experiences of perinatal mental health and service provision and focuses on midwives' experiences of supporting women with perinatal mental health problems. This paper reports on midwives' experiences through self-administered questionnaires and focus groups. Descriptive statistics were used to analyse questionnaire data and focus group data were thematically analysed. PARTICIPANTS: All midwives employed at one Health Board in South Wales UK, were eligible to participate. Recruitment took place between February and October 2018. Questionnaires were completed by 145 midwives and 15 attended one of three focus groups. FINDINGS: Questionnaire data showed the majority of midwives had cared for women with mental health problems, most commonly anxiety (95.0%, n = 138) and depression (87.0%, n = 127). Midwives assessed women's mental health informally by observing or asking questions about mood (99.3%, n = 144), anxiety levels (94.5%, n = 137), levels of support (91.0%, n = 132) and mental health history (95.9%, n = 139). The majority of midwives (82.8%, n = 120) indicated they would make some sort of mental health assessment at least 50% of the time. Around a third of midwives 31.7% (n = 46) reported receiving training relating to perinatal mental health in the previous two years, however only 21.4% (n = 31) of these suggested this had helped them in their practice. Three themes were generated from the focus groups, 1) Conversations 2) Support 3) Knowledge and skills. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: A lack of time and continuity at appointments and a focus on physical health of mother and baby reduced the opportunity for conversations around mental health. In addition a lack of experience reduced midwives' confidence resulting in a low threshold for referring women to other services for support. Midwives' main concerns were a need for training on aspects of day-to-day practice and referral options to support women's mental health. A package of training to improved skills and confidence as well as a clear pathway of care will enable midwives to be better placed to support women's mental health.

RESUMEN

OBJECTIVE: To explore the experiences of women during pregnancy with mild to moderate mental health problems and describe the barriers to receiving support in relation to their mental health. RESEARCH DESIGN AND PARTICIPANTS: This paper reports part of a larger project which recruited women and midwives in one hospital in Wales. Participants completed questionnaires in early pregnancy in an antenatal clinic, and the characteristics of women with and without symptoms of anxiety and depression compared. All women were invited to express interest in a follow up interview in late pregnancy. Women identified to have depression and anxiety in early pregnancy, but not under the care of perinatal mental health services, were eligible for interview. Interviews were conducted with 20 women using a visual timeline to aid discussion and were thematically analysed. FINDINGS: In late pregnancy mental health disorders were reported by nine women, of which five were diagnosed during adulthood. EPDS scores found 15 women had symptoms of mild to moderate depression and GAD-7 scores indicating 15 women with mild to moderate anxiety. Three themes were identified: moods and emotions - past, present and future; expectations and control; knowledge and conversations. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Due to limited access to specialist perinatal mental health services women relied on support networks and self-care to maintain their mental health. More time and better continuity at antenatal appointments along with improved mental health literacy may increase discussions regarding women's mental health during pregnancy. In addition investment is required to develop strategies and improve access to mental health services for women with mild to moderate mental health problems.

RESUMEN

OBJECTIVES: To assess the prevalence of self-reported mental health problems in a cohort of women in early pregnancy. To describe the relationship between poor mental health and sociodemographic characteristics, self-efficacy and support networks. To assess if participants were representative of the local antenatal population. RESEARCH DESIGN AND SETTING: The UK government has pledged money to provide more support for women with perinatal mental health issues. Understanding the prevalence and predicting women who may need support will inform clinical practice. This paper reports part of the larger 'Mothers Mood Study', which explored women's and midwives' experience of mild to moderate perinatal mental health issues and service provision. Routinely collected population level data were analysed and a smaller cross-sectional survey design used to assess predictors of poor mental health in early pregnancy in one health board in Wales. PARTICIPANTS: Routinely collected data were extracted for all women who registered for maternity care between May 2017 and May 2018 (n = 6312) from the electronic maternity information system (pregnant population). Over a three month period 302 of these women completed a questionnaire at the antenatal clinic after an ultrasound scan (participants). Eligible women were aged ≥18 years, with sufficient spoken and written English to complete the questionnaire and a viable pregnancy of ≤18 weeks' gestation. The questionnaire collected data on sociodemographic status, self-efficacy and support networks, self-reported mental health problems. Current anxiety and depression were assessed using the General Anxiety Disorders Assessment and Edinburgh Postnatal Depression Scale. FINDINGS: Among the pregnant population 23% (n = 1490) disclosed a mental health problem during routine questioning with anxiety and depression being the most common conditions. Participants completing the detailed questionnaire were similar in age and parity to the pregnant population with similar levels of depression (15.6%; n = 15.6 v 17.3%, n = 1092). Edinburgh Postnatal Depression Scale and General Anxiety Disorder 7 scores identified 8% with symptoms of anxiety (n = 25) or depression (n = 26) and a further 24.2% (n = 73) with symptoms of mild anxiety and 25.2% (n = 76) with mild depression. Low self-efficacy (OR 1.27, 95% CI 1.12-1.45), a previous mental health problem (OR 3.95, 95% CI 1.37-11.33) and low support from family (OR 1.13, 95% CI 1.00-1.27) were found to be associated with early pregnancy anxiety and/or depression. KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Around one in five women who register for maternity care may have a mental health problem. Mild to moderate anxiety and depression are common in early pregnancy. Services need to improve for women who do not currently meet the threshold for referral to perinatal mental health services. Assessment and active monitoring of mental health is recommended, in particular for pregnant women with risk factors including a history of previous mental health difficulties, poor family support or low self-efficacy.

RESUMEN

OBJECTIVE: To explore the potential efficacy of multi-modular motion-assisted memory desensitization and reprocessing (3MDR) in British military veterans with treatment-resistant service-related PTSD. METHODS: Exploratory single-blind, randomized, parallel arm, cross-over controlled trial with nested process evaluation to assess fidelity, adherence and factors that influence outcome. RESULTS: A total of 42 participants (all male) were randomized with 83% retention at 12 weeks and 86% at 26 weeks. The difference in mean Clinician-Administered PTSD Scale for DSM-5 scores between the immediate and delayed 3MDR arms was -9.38 (95% CI -17.33 to -1.44, P = 0.021) at 12 weeks and -3.59 (-14.39 to 7.20, P = 0.513) at 26 weeks when both groups had received 3MDR. The likely effect size of 3MDR was found to be 0.65. Improvements were maintained at 26-week follow-up. 3MDR was found to be acceptable to most, but not all, participants. Several factors that may impact efficacy and acceptability of 3MDR were identified. CONCLUSION: 3MDR is a promising new intervention for treatment-resistant PTSD with emerging evidence of effect.

RESUMEN

INTRODUCTION: Tumor mutation profiling is standard-of-care in lung carcinoma patients. However, comprehensive molecular profiling of small specimens, including core needle biopsy (CNB) and fine-needle aspiration (FNA) specimens, may often be inadequate due to limited tissue. Centrifuged FNA supernatants, which are typically discarded, have emerged recently as a novel liquid-based biopsy for molecular testing. In this study, we evaluate the use of lung carcinoma FNA supernatants for detecting clinically relevant mutations. METHODS: Supernatants from lung carcinoma FNA samples (n = 150) were evaluated. Samples were further analyzed using next-generation sequencing (NGS) and ultrasensitive droplet digital PCR (ddPCR). Mutation profiles in a subset of samples were compared with results derived from paired tissue samples from the same patient (n = 67) and available plasma liquid biopsy assay (n = 45). RESULTS: All 150 samples yielded adequate DNA and NGS were carried out successfully on 104 (90%) of 116 selected samples. Somatic mutations were detected in 82% of the samples and in 50% of these patients a clinically relevant mutation was identified that would qualify them for targeted therapy or a clinical trial. There was high overall concordance between the mutation profiles of supernatants and the corresponding tissue samples, with 100% concordance with concurrent FNA and 96% with concurrent CNB samples. Comparison of actionable driver mutations detected in supernatant versus plasma samples showed 84% concordance. CONCLUSIONS: FNA supernatants can provide a valuable specimen source for genotyping lung carcinoma especially in patients with insufficient tumor tissue, thereby reducing multigene mutation profiling failure rates, improving turnaround times, and avoiding repeat biopsies.

RESUMEN

Across the UK, mental health professionals are strongly objecting to threats to their roles. Against this background we use ethnographic data from a study of roles and responsibilities in community care, undertaken across two contrasting sites in Wales, to demonstrate how work is sensitive to local organizational features and to show how gaps can grow between the public claims professions make about their contributions and the actual roles which their members fulfil in the workplace. We reveal how, in one of our two research sites, immediate contextual features shaped the work of nurses and social workers towards the fulfilment of expanded packages of activity. We then show how subsequent policy (including 'new ways of working'), combined with new pressures arising from the economic downturn, carry the potential to accelerate the wider creation of workplaces of this type. We examine some implications of these processes for nurses and others, and for the system of mental health care as a whole, and conclude with a call for closer attention to be paid to the potential, wider, impact of current developments.

RESUMEN

Higher speeds are associated with increases in the probability of crashing and the severity of the outcome. Logically drivers speed to save time, and research evidence supports this assertion. It is therefore important to investigate drivers' understanding of how speed change impacts on journey time. Since it is likely that drivers do not appreciate the reciprocal nature of the function which links these two variables, and its implications, two predictions can be made: the impact of a speed change will be underestimated at low speeds and overestimated at high speeds. This issue was addressed through four questions generated by manipulating Speed Change (increase versus decrease) and Starting Speed (30 mph versus 60 mph) with the participants being asked how they felt these variables would impact on journey time. These were included in a large survey addressing speed-related issues. Participants were a representative quota sample of 1005 UK drivers, interviewed by questionnaire. The findings indicated that three of the four questions produced results consistent with the predictions made. Furthermore, a repeated measures factorial ANOVA indicated that there was no real appreciation of how starting speed impacted on journey time. A disordinal interaction provided evidence that drivers wrongly believed that as starting speed increased the impact of a speed rise also increased; the opposite is true. For speed decreases, drivers appeared to think that starting speed had little impact on the amount of time saved. It is recommended that these findings be integrated into driver training and speed awareness courses.

RESUMEN

OBJECTIVE: To determine zinc status and age-related changes in the immune function of healthy late-middle-aged men and women (aged 55-70 y). DESIGN: Observational study. SETTING: Population of Northern Ireland. SUBJECTS: Apparently healthy, free-living individuals (45 men, 48 women) aged 55-70 y. INTERVENTION: Zinc status markers were analysed by flame atomic absorption spectrometry and commercially available kits. Immune function was assessed by flow cytometry. RESULTS: Serum and erythrocyte zinc concentrations were 13.0 (s.d. 1.40) micromol/l and 222 (s.d. 48.2) micromol/l, respectively. Serum alkaline phosphatase (ALP) concentrations were 76.8 (s.d. 16.1) U/l; women showed significantly higher concentrations of ALP (P = 0.011). Women demonstrated (1) a significant inverse correlation in naive T lymphocytes, specifically naive T-helper lymphocytes (% expression, r = -0.364, P = 0.007 and absolute count, r = -0.275, P = 0.036) with age and (2) a significant positive correlation between late activation of T lymphocytes (% expression, r = 0.299, P = 0.019 and absolute count, r = 0.260, P = 0.039) with advancing age. Men demonstrated a significant positive correlation in the % expression of (CD3-/CD16+/CD56+) natural killer (NK) cells with age (r = 0.316, P = 0.017). CONCLUSIONS: Between the ages of 55 and 70 y, healthy individuals experience significant alterations in immune function; however, such changes appear largely sex specific. Given the reported importance of adequate zinc status in maintaining optimal immune function, further studies are required to explore the effect of enhanced zinc status on emerging immune deficiencies in cell-mediated immunity in healthy 55-70 y olds.

RESUMEN

AIMS: The onset of complications in Type 2 diabetes mellitus (DM) patients cannot be predicted in individuals. Evidence suggests a link between complications and hyperglycaemia, oxidative stress and antioxidants, but causality is unclear. This study investigated baseline (entry) fasting plasma ascorbic acid, lymphocytic DNA damage and glycaemic control in Type 2 DM as part of a long-term study, the aim of which is to explore a biomarker profiling approach to identify and improve outcome in high-risk subjects. METHODS: A cross-sectional study, in which DNA damage, glycated haemoglobin (HbA(1c)), fasting plasma glucose (FPG) and ascorbic acid (AA) were measured on fasting blood samples collected from 427 Type 2 DM subjects. RESULTS: DNA damage was significantly (P < 0.0001) and directly correlated to both FPG (r = 0.540) and HbA(1c) (r = 0.282), and was significantly (P < 0.0001), independently and inversely correlated to plasma AA (r = -0.449). In those subjects with both poor glycaemic control and low AA (< 48 microm, the overall mean value for the study group), DNA damage was significantly (P < 0.005) higher compared with those subjects with a similar degree of hyperglycaemia but with AA above the mean. CONCLUSIONS: The novel finding of a significant inverse relationship between plasma AA and DNA damage in Type 2 DM indicates that poorly controlled diabetic subjects might benefit from increased dietary vitamin C. The data also have important implications for biomarker profiling to identify those subjects who might benefit most from intensive therapy. Longer-term follow-up is underway.

RESUMEN

Clinical supervision is widely accepted as an essential prerequisite for high quality nursing care. This paper reports findings from a study that aims to identify the factors that may influence the effectiveness of clinical supervision for community mental health nurses (CMHNs) in Wales, UK. Two hundred and sixty (32%) CMHNs from an estimated total population of 817 completed the Manchester Clinical Supervision Scale (MCCS) and a demographic questionnaire. The MCCS is a 36-item questionnaire measuring the quality and effectiveness of the supervision received. Three-quarters of CMHNs reported having participated in six or more sessions of supervision in their current posts. Clinical supervision was more positively evaluated where sessions lasted for over one hour, and took place on at least a once-monthly basis. Perceived quality of supervision was also higher for those nurses who had chosen their supervisors, and where sessions took place away from the workplace. These findings have important implications for the organization and delivery of mental health nursing services.

RESUMEN

Ageing affects feline lymphocyte homeostasis in a similar pattern to that observed in other long-lived mammalian species, contributing to increased levels of morbidity and mortality in the ageing cat. Insulin-like growth factor-I (IGF-I) is now recognised as an important endocrine regulator of immunity and has been shown to decline with age in humans and rodent species. Analysis of plasma IGF-I in adult and senior cats confirmed that the older cats had significantly lower circulating levels of IGF-I. In order to determine whether an association existed between lymphocyte subpopulations and IGF-I levels in the cat, each parameter was measured and subjected to regression analysis. A highly significant association was found in vivo between plasma IGF-I and CD4(+) T-cell values in the senior group, but no such association was observed in the adult group. In order that this relationship could be examined further, in vitro studies were undertaken to investigate the effects of physiologically relevant concentrations of recombinant human IGF-I (rhIGF-l) on peripheral blood lymphocyte (PBL) cultures from adult and senior cats. While rhlGF-I induced low-level thymidine incorporation in the lymphocytes isolated from the senior group, it did not enhance the proliferative response to T-cell mitogens, Con A and PHA in either group, nor did it rescue cells from oxidatively induced apoptosis. Furthermore, the proliferative response of PBL from seniors did not attain the magnitude of that from the adults at any concentration of rhIGF-l. We propose that the observed association is not a direct effect of IGF-I on PBL, but may be mediated through an effect of IGF-I on the thymus.

RESUMEN

Oxidative stress is implicated in the aetiology of many diseases; however, most supplementation trials with antioxidant micronutrients have not shown expected beneficial effects. This randomized, double-blinded, placebo-controlled study evaluated acute effects (at 90, 180min and 24h [fasting] post-ingestion) of single doses of Vitamins C (500mg) and E (400IU), alone and in combination, on biomarkers of plasma antioxidant status, lipid peroxidation and lymphocyte DNA damage in 12 healthy, consenting volunteers. Plasma ascorbic acid increased significantly (P < 0.01) within 2h of ingestion of Vitamin C, and alpha-tocopherol was significantly (P < 0.01) higher at 24h post-ingestion Vitamin E. The pattern of response was not significantly different whether Vitamin C (or Vitamin E) was taken alone or in combination, indicating no augmentation of response to one by co-ingestion of the other vitamin. No significant changes were seen in plasma FRAP in the group overall (although increases (P < 0.05) were seen at 90 and 180min post-ingestion in women after Vitamin C ingestion) or in MDA across treatments, and no evidence of increased DNA damage, or of DNA protection, was seen at any time point after Vitamin C and/or E ingestion. In conclusion, the data from this first controlled study of acute effects of single doses of Vitamin C and/or E show no evidence of either a protective or deleterious effect on DNA damage, resistance of DNA to oxidant challenge, or lipid peroxidation. No evidence of a synergistic or cooperative interaction between Vitamins C and E was seen, but further study is needed to determine possible interactive effects in a staggered supplementation cycle, and study of subjects under increased oxidative stress or with marginal antioxidant status would be useful. It would be of interest also to study the effects of these vitamins ingested with, or in, whole food, to determine if they are directly protective at doses above the minimum required to prevent deficiency, if combinations with other food components are needed for effective protection, or if Vitamins C and E are largely surrogate biomarkers of a 'healthy' diet, but are not the key protective agents.

RESUMEN

In order to assess age-related differences in feline immune status, 101 domestic short haired cats were assigned to two groups, adult (2-5 years, n=50) and senior (10-14 years, n=51). Analyses of leucocyte populations, lymphocyte subsets, complement activity, serum immunoglobulins and acute-phase proteins were undertaken and revealed significant differences between the two groups. The senior group had significantly lower WBC, lymphocyte and eosinophil counts than the adult group. Neutrophil, monocyte and basophil counts did not differ between the groups. Flow cytometry analysis, in combination with differential WBC data, revealed that the absolute values (cells/l) of T-cells, B-cells and natural killer (NK) cells were significantly lower in the older animals. While serum immunoglobulins IgA and IgM were higher in the senior group when compared with the adult group, no significant differences were observed in complement activity or in serum acute-phase proteins. Our findings suggest that age-related changes to parameters of immune status in the feline model are likely to follow a similar pattern to those observed in other long-lived mammalian species.

RESUMEN

Human lymphocytes have low levels of many antioxidant enzymes however they are know to concentrate vitamin C. Cell injury, including oxidative stress effects, is associated with calcium influx so the influence of vitamin C on the maintenance of calcium levels in leukocytes was studied. Incubation of Molt-3 human lymphoblastoid cells with physiologically relevant concentrations of vitamin C and the calcium ionophore A23187 reversed the calcium influx and increased nuclear protein level associated with the ionophore alone. It is concluded that intracellular vitamin C can inhibit calcium influx into leukocytes so helping to minimise cell damage.

RESUMEN

Surveys of the leaders of the UK's post-qualifying education courses for community mental health nurses have taken place, on an annual basis, for over 10 years. In this paper, findings from the survey undertaken in the 1998--99 academic year are reported. These findings include: that most course leaders do not personally engage in clinical practice; that interprofessional education takes place at a minority of course centres, and that course philosophies and aims are characterised by an emphasis on both outcomes (in terms of, for example, skills acquisition, knowledge development and the ability to engage in reflective practice), and process (adult learning).

RESUMEN

Publishing in peer reviewed journals is an essential activity for nurses working in higher education. This paper offers some reflections on the processes involve in the reviewing of articles submitted for publication, and explores some ways in which this system may be improved. All journals operate some kind of review process. This can range from, at one end, the editor making decisions about the suitability for publication of a submitted paper to, at the other end, papers being blind-reviewed by two (or sometimes more) external referees. This paper notes that there appears to be little or no consistency amongst the various nursing journals with respect to reviewing processes. Suggestions put forward in this article for consideration include: the standardisation of peer review systems across journals; the construction of guidelines for referees which caution against ad hominem attacks on authors; and the introduction of 'open' reviewing.

RESUMEN

BACKGROUND: Nasal polyposis often coexists with asthma in airway inflammatory conditions characterised by the infiltration of a range of immune cells. A potentially important role for ovarian hormones has been implicated in airway inflammation but the cellular target for such action is not known. METHODS: Expression of oestrogen receptors (ER) and progesterone receptors (PR) was examined using immunohistochemistry in formalin fixed nasal polyp tissues from 47 subjects. The cells positive for ER or PR were confirmed by spatial location, dual immunolabelling, and histochemical staining. RESULTS: Consistent with the known features of nasal polyps, CD4+ (T helper/inducer), CD8+ (cytotoxic/suppressor), CD68+ (macrophages), mast cells, eosinophils and neutrophils were all clearly detected by their relevant monoclonal antibodies or appropriate histochemical staining, but only mast cells tested positive for ER/PR labelling with their polyclonal and monoclonal antibodies. The frequencies for expression were 61.7% for ER positive and 59.6% for PR positive cells. The expression of ER/PR was independent of patient sex and age but was highly correlated with the numbers of mast cells (r = 0.973, p<0.001 for ER; r = 0.955, p<0.001 for PR). Fewer than 5% of mast cells were found to be negative for ER/PR expression. CONCLUSIONS: Mast cells alone, but not lymphocytes, macrophages, or other immune cells, express ER/PR in human upper airways. Numerous ER/PR positive mast cells exist in nasal polyps, indicating that this may be a major route for the involvement of sex hormones in airway inflammation when exposed to the higher and varying concentration of oestrogen and progesterone characteristic of females.

RESUMEN

AIMS: The aim of the study was to examine the variety, frequency and severity of stressors experienced by community mental health nurses (CMHNs) in Wales. BACKGROUND: Numerous studies undertaken throughout the United Kingdom (UK) have indicated that those health professionals working as part of community teams are experiencing increasing levels of stress and burnout. Sample sizes have tended to be small and participants have been drawn mainly from sites in England. METHODS: A questionnaire booklet, which included a number of validated measures, was distributed to 614 CMHNs. These included Maslach Human Services Survey, Community Psychiatric Nursing (CPN) Stress Questionnaire, PsychNurse Coping Questionnaire, Rosenberg Self-Esteem Scale and General Health Questionnaire GHQ-12. The study was the largest of its kind conducted in the UK. RESULTS: Data were collected from 301 CMHNs, representing a response rate of 49%. Community mental health nurses identified the most stressful issues as trying to maintain a good quality service in the midst of long waiting lists and poor resources and having too many interruptions while trying to work in the office. The best demographic predictors of high stress scores were having an unsupportive line manager, working with a specific client group and not having job security. These factors accounted for 20% of the variance in the total stress score. When the results from the psychometric instruments were included, 46% of the variance in the total stress score was accounted for. The predictive variables were emotional exhaustion, working with a specific client group, job security and alcohol consumption. CONCLUSIONS: These findings indicate that there is a need to create more supportive environments both in terms of job security and management support, especially for those working in the fields of severe mental illness and rehabilitation.

RESUMEN

Nurses studying for undergraduate degrees are often required to produce a dissertation. Usually, this will be a piece of work of around 10,000 words in length. In this paper, we discuss the characteristics of a good dissertation, and discuss a range of s trategies which students might find useful as they work towards dissertation submission. Particular areas that we concentrate on include: getting started, working with supervisors, defining aclear topic area, planning work and timetabling, locating and critiquing literature, writing up the literature review, linking theory and practice, and knitting the dissertation together.
