Preserving Control: Understanding People's Experiences Before, During and After Detention Under the Irish Mental Health Act 2001

Introduction

The Mental Health Act 2001 provides a legal framework for the involuntary admission and treatment of individuals deemed to have a mental disorder to psychiatric units. The perspectives of people who have been detained are relatively poorly understood.

Objective

To develop a theoretical understanding of individual's experiences throughout the trajectory of their detention and to understand the psychological and social processes that individuals use to cope before, during and after detention.

Methods

Fifty individuals subject to detention across three psychiatric units consented to be interviewed three months after their detention. Using a semi-structured interview people recounted their experiences. Interviews were analysed using the principles underpinning Grounded Theory.

Results

The theory ‘Preserving Control’ encapsulates individuals’ experiences and consists of three related themes: ‘Losing Control’, ‘Regaining Control’ and ‘Maintaining Control’. ‘Losing Control’ describes individuals’ experiences of losing their autonomy and liberty thought the process of detention and hospitalisation. ‘Regaining Control describes, the strategies individuals used in an attempted to restore their loss of autonomy and control. ‘Maintaining Control’ describes how individuals lived with the consequences of detention and contended with impact on discharge.

Conclusions

Whilst a large variation existed in relation to the subjective experience of being detained, the characteristic process that individuals tend to experience related to identifiable phases of preserving control in the face of this loss of autonomy. Findings from this study highlight the importance of more sensitive interactions support and information during and after the detention process.

Treatment of 213 Patients with Symptomatic Tarlov Cysts by CT-Guided Percutaneous Injection of Fibrin Sealant

BACKGROUND AND PURPOSE

There has been a steady progression of case reports and a small surgical series that report successful surgical treatment of Tarlov cysts with concomitant relief of patients' symptoms and improvement in their neurological dysfunction, yet patients are still told that these lesions are asymptomatic by physicians. The purpose of this study was to analyze the efficacy and safety of intervention in 213 consecutive patients with symptomatic Tarlov cysts treated by CT-guided 2-needle cyst aspiration and fibrin sealing.

MATERIALS AND METHODS

This study was designed to assess outcomes in patients who underwent CT-guided aspiration and injection of ≥1 sacral Tarlov cyst at Johns Hopkins Hospital between 2003 and 2013. In all, 289 cysts were treated in 213 consecutive patients. All these patients were followed for at least 6 months, 90% were followed for 1 year, and 83% were followed for 3-6 years. The aspiration-injection procedure used 2 needles and was performed with the patients under local anesthesia and intravenous anesthesia. In the fibrin-injection stage of the procedure, a commercially available fibrin sealant was injected into the cyst through the deep needle (Tisseel VH).

RESULTS

One year postprocedure, excellent results were obtained in 104 patients (54.2% of patients followed), and good or satisfactory results were obtained in 53 patients (27.6%). Thus, 157 patients (81.8%) in all were initially satisfied with the outcome of treatment. At 3-6 years postprocedure, 74.0% of patients followed were satisfied with treatment. There were no clinically significant complications.

CONCLUSIONS

The aspiration-injection technique described herein constitutes a safe and efficacious treatment option that holds promise for relieving cyst-related symptoms in many patients with very little risk.

Abstract POSTER-CTRL-1205: Neurocognitive evaluation of a cognitive training intervention in ovarian and gynecologic cancer survivors

Purpose: Our prior work indicates that a group-based cognitive training intervention can improve memory and attention in cancer survivors. This study examined potential for training transfer on two cognitive tasks and corresponding changes in neural activation patterns as measured by fMRI prior to and following the cognitive training intervention.

Methods: Seven gynecologic cancer (ovarian, breast, uterine) survivors (mean age: 64 years, mean time since primary treatment: 7.2 years) underwent a 7-week cognitive rehabilitation intervention delivered in group format. Participants were evaluated with a comprehensive cognitive battery and two experimental cognitive tasks prior to and following treatment. A word pair task required participants to learn pairs of words and later indicate whether words had been seen before (Item condition) or whether words had been paired together at learning (Relational condition). A verbal working memory task required participants to learn a set of 3, 5, or 7 letters and confirm or deny the presence of a probe letter. Participants also underwent fMRI scanning during word pair and verbal working memory tasks prior to and following treatment.

Results: Participants showed significant improvement following intervention in accuracy in the Relational condition, in which strong associations between presented word pairs were required for successful performance, t(3)=5.21, p< .05. By contrast, accuracy did not increase significantly in the Item condition following intervention, t(3)=.48, p=.66). There was also a significant improvement in accuracy for the intermediate load (5-item) condition of the verbal working memory task following intervention, t(3)=4.17, p<.05. fMRI analyses revealed activation in a frontoparietal network during both the word pairs and verbal working memory tasks. Future analyses will investigate changes in recruitment of this network following intervention.

Conclusions: Cancer survivors show evidence of specific transfer of memory skills following a group-based cognitive training intervention as demonstrated by improvement on the word memory task- relational item. In addition, there was a trend toward improvement on a working memory task. Neuroimaging results suggest frontoparietal network involvement for the cognitive task as well as some indication of a more efficient neural response following training. These results suggest that cognitive training may have a beneficial impact on both behavioral measures of cognition as well as neural activation markers.

The midwife's role in providing smoking cessation interventions for pregnant women: The views of midwives working with high risk, disadvantaged women in public sector antenatal services in South Africa

OBJECTIVE

The purpose of this study was to assess the knowledge, attitudes, beliefs and current practices of South Africa midwives in relation to providing smoking cessation education or counselling to pregnant women. This was with a view to involving them in a potential smoking cessation intervention, targeting a sub-group of South African women who are at particularly high risk of the adverse pregnancy outcomes associated with smoking.

DESIGN

A cross-sectional survey of midwives, supplemented by individual, in depth, qualitative interviews.

SETTING

Public sector antenatal clinics serving this particular community of women in five of the major urban centres of South Africa.

PARTICIPANTS

A total of 102 midwives were surveyed across 29 antenatal clinics and 24 were interviewed.

MEASUREMENTS

Self-administered survey and semi-structured, individual interviews describing constructs from the Theory of Planned Behaviour with respect to the provision of smoking cessation education/counselling, including: knowledge, attitudes, subjective norms and perceived behavioural control.

FINDINGS

The majority of midwives accepted that providing smoking cessation advice was a part of their remit, perceived prevailing social norms to be supportive and were, overall, positively predisposed to participating in a smoking cessation intervention in antenatal clinics. However, the study identified a number of constraints to midwives fulfilling this role, which affected their perceived behavioural control. These included stressful working conditions, too little time, a dearth of educational resources and a lack of knowledge of best practice intervention methods and counselling skills. Perceived patient resistance to quitting was a further obstacle.

KEY CONCLUSIONS AND IMPLICATIONS FOR PRACTICE

For the intervention to be accepted and adopted by midwives, it would need to offer them an opportunity to enhance their professional knowledge and expertise, provide them with attractive educational aids and take into account the very limited time they have for smoking education. Patient-centred, best practice methods for cessation counselling may help midwives overcome the problem of patient resistance and to engage smokers in constructive discussions about smoking with a greater prospect of success.

Does this child really have a penicillin allergy?

Penicillins, the most prescribed paediatric medications worldwide, are also the most commonly reported cause of medication allergy, although this is rarely confirmed. An oral penicillin challenge is considered the gold standard in assessing children with suspected allergy but is seldom performed due to lack of appropriately trained staff and insufficient facilities. We introduced a standardised nurse-led protocol to evaluate children with suspected penicillin allergy fulfilling low risk criteria. In total, 40 children participated, including 22 girls and 18 boys, of which 38 met study criteria. There were 36 (95%) negative challenges completed, allowing these children to be safely prescribed oral penicillin in the future. There were 2 (5%) positive challenges developing similar signs to their initial reaction. This standardised protocol appears to be safe for use and efficient in the evaluation of low risk children with suspected penicillin allergy.

Safety of sublingual immunotherapy Timothy grass tablet in subjects with allergic rhinitis with or without conjunctivitis and history of asthma

BACKGROUND

Patients with asthma may be more susceptible to adverse events (AEs) with sublingual immunotherapy tablet (SLIT-tablet) treatment, such as severe systemic reactions and asthma-related events. Using data from eight trials of grass SLIT-tablet in subjects with allergic rhinitis with/without conjunctivitis (AR/C), AE frequencies were determined in adults and children with and without reported asthma.

METHODS

Data from randomized, double-blind, placebo-controlled trials of Timothy grass SLIT-tablet MK-7243 (2800 BAU/75 000 SQ-T, Merck/ALK-Abelló) were pooled for post hoc analyses. Subjects with uncontrolled and severe asthma were excluded from the trials. Frequencies for treatment-emergent AEs (TEAEs), local allergic swelling (mouth or throat), systemic allergic reactions, and asthma-related treatment-related AEs (TRAEs) were calculated.

RESULTS

Among adults (n = 3314) and children (n = 881), 24% and 31%, respectively, had reported asthma. No serious local allergic swellings or serious systemic allergic reactions occurred in subjects with asthma treated with SLIT-tablet. There was no evidence of increased TEAEs, systemic allergic reactions, or severe local allergic swellings in adults or children with asthma treated with grass SLIT-tablet versus subjects without asthma in or outside of pollen season. There were 6/120 asthma-related TRAEs assessed as severe with grass SLIT-tablet and 2/60 with placebo, without a consistent trend among subjects with and without asthma (5 and 3 events, respectively).

CONCLUSIONS

In the AR/C subjects with reported well-controlled mild asthma included in these studies, grass SLIT-tablet did not increase TEAE frequency, severe local allergic swelling, or systemic allergic reactions versus subjects without asthma. There was no indication that treatment led to acute asthma worsening.

Paternal influence of sperm DNA integrity on early embryonic development

STUDY QUESTION

Does sperm DNA damage affect early embryonic development?

SUMMARY ANSWER

Increased sperm DNA damage adversely affects embryo quality starting at Day 2 of early embryonic development and continuing after embryo transfer, resulting in reduced implantation rates and pregnancy outcomes.

WHAT IS KNOWN ALREADY

Abnormalities in the sperm DNA in the form of single and double strand breaks can be assessed by an alkaline Comet assay. Some prior studies have shown a strong paternal effect of sperm DNA damage on IVF outcome, including reduced fertilization, reduced embryo quality and cleavage rates, reduced numbers of embryos developing into blastocysts, increased percentage of embryos undergoing developmental arrest, and reduced implantation and pregnancy rates.

STUDY DESIGN, SIZE, DURATION

A cross-sectional study of 215 men from infertile couples undergoing assisted reproduction techniques at the University of Utah Center for Reproductive Medicine.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Sperm from men undergoing ART were analyzed for DNA damage using an alkaline Comet assay and classified into three groups: 'low damage' (0-30%), 'intermediate damage' (31-70%) and 'high damage' (71-100%). The cause of couples' infertility was categorized into one of the three types (male, female or unexplained). Each embryo was categorized as 'good', 'fair' or 'poor' quality, based on the number and grade of blastomeres. The influence of sperm DNA damage on early embryonic development was observed and classified into four stages: peri-fertilization effect (fertilization rate), early paternal effect (embryonic days 1-2), late paternal effect (embryonic days 3-5) and implantation stage effect.

MAIN RESULTS AND THE ROLE OF CHANCE

The paternal effect of sperm DNA damage was observed at each stage of early embryonic development. The peri-fertilization effect was higher in oocytes from patients with female infertility (20.85%) compared with male (8.22%; P < 0.001) and unexplained (7.30%; P < 0.001) infertility factors. In both the early and late paternal effect stages, the low DNA damage group had a higher percentage of good quality embryos (P < 0.05) and lower percentage of poor quality embryos (P < 0.05) compared with the high DNA damage group. Implantation was lower in the high DNA damage (33.33%) compared with intermediate DNA damage (55.26%; P < 0.001) and low DNA damage (65.00%; P < 0.001) groups. The implantation rate was higher following blastocyst transfer (58.33%), when compared with early stage blastocyst (53.85%; P = 0.554) and cavitating morula transfers (34.40%; P < 0.001). Implantation was higher when the female partner age was ≤35 years when compared with >35 year age group (52.75 versus 35.44%; P = 0.008).

LIMITATIONS, REASONS FOR CAUTION

A potential limitation of this study is that it is cross-sectional. Generally in such studies more than one variable could affect the outcome. Analyzing sperm is one part of the equation but a number of environmental and female factors also have the potential to influence embryo development and implantation. Furthermore, the selection of morphologically normal and physiologically motile sperm may result in isolation of sperm with reduced DNA damage. Therefore, selecting the best available sperm for ICSI may lead to experimental bias, as the selected sperm do not represent the overall sperm population in which the DNA damage is measured. Similar studies on selected sperm and with a larger sample size are now required.

WIDER IMPLICATIONS OF THE FINDINGS

The paternal influence of damaged chromatin is more prominent after zygotic transcriptional activation. A prolonged paternal effect on the developing embryo may be due to the active repair mechanism present in oocytes that tends to overcome the damaged paternal chromatin. The probability of eliminating an embryo fertilized by a sperm with damaged DNA is higher at the blastocyst stage than the cleavage stage; therefore blastocyst transfer could be recommended for better implantation success. Finally, we recommend ICSI treatment for patients with a higher percentage of sperm with DNA damage as well as additional studies with a larger sample size aimed at assessing DNA damage analysis as a diagnostic tool for IVF.

Genome-wide distribution of Auts2 binding localizes with active neurodevelopmental genes

The autism susceptibility candidate 2 gene (AUTS2) has been associated with multiple neurological diseases including autism spectrum disorders (ASDs). Previous studies showed that AUTS2 has an important neurodevelopmental function and is a suspected master regulator of genes implicated in ASD-related pathways. However, the regulatory role and targets of Auts2 are not well known. Here, by using ChIP-seq (chromatin immunoprecipitation followed by deep sequencing) and RNA-seq on mouse embryonic day 16.5 forebrains, we elucidated the gene regulatory networks of Auts2. We find that the majority of promoters bound by Auts2 belong to genes highly expressed in the developing forebrain, suggesting that Auts2 is involved in transcriptional activation. Auts2 non-promoter-bound regions significantly overlap developing brain-associated enhancer marks and are located near genes involved in neurodevelopment. Auts2-marked sequences are enriched for binding site motifs of neurodevelopmental transcription factors, including Pitx3 and TCF3. In addition, we characterized two functional brain enhancers marked by Auts2 near NRXN1 and ATP2B2, both ASD-implicated genes. Our results implicate Auts2 as an active regulator of important neurodevelopmental genes and pathways and identify novel genomic regions that could be associated with ASD and other neurodevelopmental diseases.

²¹³Bi-DOTATOC receptor-targeted alpha-radionuclide therapy induces remission in neuroendocrine tumours refractory to beta radiation: a first-in-human experience

Purpose

Radiopeptide therapy using a somatostatin analogue labelled with a beta emitter such as ⁹⁰Y/¹⁷⁷Lu-DOTATOC is a new therapeutic option in neuroendocrine cancer. Alternative treatments for patients with refractory disease are rare. Here we report the first-in-human experience with ²¹³Bi-DOTATOC targeted alpha therapy (TAT) in patients pretreated with beta emitters.

Methods

Seven patients with progressive advanced neuroendocrine liver metastases refractory to treatment with ⁹⁰Y/¹⁷⁷Lu-DOTATOC were treated with an intraarterial infusion of ²¹³Bi-DOTATOC, and one patient with bone marrow carcinosis was treated with a systemic infusion of ²¹³Bi-DOTATOC. Haematological, kidney and endocrine toxicities were assessed according to CTCAE criteria. Radiological response was assessed with contrast-enhanced MRI and ⁶⁸Ga-DOTATOC-PET/CT. More than 2 years of follow-up were available in seven patients.

Results

The biodistribution of ²¹³Bi-DOTATOC was evaluable with 440 keV gamma emission scans, and demonstrated specific tumour binding. Enduring responses were observed in all treated patients. Chronic kidney toxicity was moderate. Acute haematotoxicity was even less pronounced than with the preceding beta therapies.

Conclusion

TAT can induce remission of tumours refractory to beta radiation with favourable acute and mid-term toxicity at therapeutic effective doses.

A correlation between severe haemolytic disease of the fetus and newborn and maternal ABO blood group

OBJECTIVE

To analyse anti-D quantification levels and frequency of intrauterine transfusion (IUT), per maternal ABO blood group.

BACKGROUND

Maternally derived red cell allo-antibodies can target fetal red cell antigens in utero leading to haemolytic disease and fetal anaemia. When a clinically significant allo-antibody is formed the priority is ascertaining the risk to the fetus and maternal ABO blood groups are not considered relevant.

MATERIALS AND METHODS

This was a 10-year retrospective, observational study carried out on women referred for anti-D quantification (n = 1106), and women whose fetuses required an IUT to treat fetal anaemia (n = 62) due to anti-D, in the Republic of Ireland.

RESULTS

Relative to the overall incidence of RhD allo-immunisation by blood group, women of blood group A were more likely to require IUT compared with those who were blood group O (P = 0.002).

CONCLUSION

It is known that ABO feto-maternal compatibility can influence the incidence and level of red cell allo-antibodies in pregnancy; however, it does not account for the significantly high rate of severe haemolytic disease requiring IUT seen in blood group A women.

The present and future disease burden of hepatitis C virus (HCV) infection with today's treatment paradigm

The disease burden of hepatitis C virus (HCV) is expected to increase as the infected population ages. A modelling approach was used to estimate the total number of viremic infections, diagnosed, treated and new infections in 2013. In addition, the model was used to estimate the change in the total number of HCV infections, the disease progression and mortality in 2013-2030. Finally, expert panel consensus was used to capture current treatment practices in each country. Using today's treatment paradigm, the total number of HCV infections is projected to decline or remain flat in all countries studied. However, in the same time period, the number of individuals with late-stage liver disease is projected to increase. This study concluded that the current treatment rate and efficacy are not sufficient to manage the disease burden of HCV. Thus, alternative strategies are required to keep the number of HCV individuals with advanced liver disease and liver-related deaths from increasing.

Comparative analysis of three sperm DNA damage assays and sperm nuclear protein content in couples undergoing assisted reproduction treatment

STUDY QUESTION

Is there an association between sperm DNA damage, measured by three different assays, sperm nuclear protein content and clinical outcomes in assisted reproduction treatment (ART)?

SUMMARY ANSWER

Sperm DNA damage measured by terminal deoxynucleotidyltransferase-mediated dUTP nick-end labelling (TUNEL) and the Comet assay were significantly associated with ART outcomes in our single institution study.

WHAT IS KNOWN ALREADY

Abnormal protamine expression is known to be associated with sperm DNA damage and male infertility. A number of studies have shown a significant relationship between sperm DNA damage and ART outcomes. To date, there are no large studies providing direct comparisons of DNA damage tests within the same study population. Thus, the prognostic value for each method remains unknown.

STUDY DESIGN, SIZE, DURATION

Cross-sectional study of 238 men from infertile couples undergoing ART at the University Center for Reproductive Medicine, Utah, USA, between April 2011 and March 2013.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Sperm from men undergoing ART were tested for DNA damage using the alkaline Comet assay, TUNEL and flow cytometric chromatin evaluation (FCCE) assays. Histone retention was analysed using the aniline blue staining method, whereas protamine content (proteins P1 and P2) and ratio were analysed using acid urea gel electrophoresis. The prognostic value of each sperm DNA test to predict clinical pregnancy was calculated.

MAIN RESULTS AND THE ROLE OF CHANCE

Histone retention was associated with sperm DNA damage (P < 0.001), reduced embryo quality (P = 0.005) and clinical pregnancies (P < 0.001). The mean percentage of sperm with DNA damage was significantly higher in sperm from non-pregnant couples compared with that from pregnant couples, as measured by TUNEL assay (15.04 ± 1.16% versus 8.79 ± 0.56%; P < 0.001) and alkaline Comet assay (72.79 ± 2.49% versus 55.86 ± 2.29%; P < 0.001). There was no association between clinical pregnancies and DNA fragmentation index measured by FCCE (12.97 ± 1.46 versus 14.93 ± 1.65; P = 0.379). Of the protamine parameters analysed, only the P1/P2 ratio was associated with sperm count (P = 0.013), men's age (P = 0.037), maturity (P = 0.049) and blastocyst quality (P = 0.012). Histone retention and sperm DNA damage measured by Comet and TUNEL assays were associated with fertilization rate (P < 0.05), embryo quality (P < 0.05) and implantation rate (P < 0.05).

LIMITATIONS, REASONS FOR CAUTION

A potential drawback of this study is that it is cross-sectional. Generally in such studies there is more than one variable that could cause the effect. Analysing sperm is one part of the equation; there are also a number of female factors that have the potential to influence ART outcomes. Therefore, given the large and well-established role of female factors in infertility, normal sperm DNA integrity and protamination do not necessarily ensure clinical pregnancy in ART. Thus, female factors can reduce the prognostic value of sperm DNA tests. Further, our use of native semen instead of prepared sperm may have iatrogenically increased the DNA damage.

WIDER IMPLICATIONS OF THE FINDINGS

Alteration in sperm nuclear protein affects sperm DNA integrity. Further, with the current dataset, TUNEL and Comet assays appeared more predictive of ART success than FCCE.
