When is the best time to screen for perinatal anxiety? A longitudinal cohort study.

BACKGROUND: For screening for anxiety during pregnancy and after birth to be efficient and effective it is important to know the optimal time to screen in order to identify women who might benefit from treatment. AIMS: To determine the optimal time to screen for perinatal anxiety to identify women with anxiety disorders and those who want treatment. A secondary aim was to examine the stability and course of perinatal anxiety over time. METHODS: Prospective longitudinal cohort study of 2243 women who completed five screening questionnaires of anxiety and mental health symptoms in early pregnancy (11 weeks), mid-pregnancy (23 weeks), late pregnancy (32 weeks) and postnatally (8 weeks). Anxiety and mental health questionnaires were the GAD7, GAD2, SAAS, CORE-10 and Whooley questions. To establish presence of anxiety disorders diagnostic interviews were conducted with a subsample of 403 participants. RESULTS: Early pregnancy was the optimal time to screen for anxiety to identify women with anxiety disorders and women wanting treatment at any time during pregnancy or postnatally. These findings were consistent across all five questionnaires of anxiety and mental health. Receiving treatment for perinatal mental health problems was most strongly associated with late pregnancy and/or postnatal assessments. Anxiety symptoms were highest in early pregnancy and decreased over time. CONCLUSION: Findings show that screening in early pregnancy is optimal for identifying women who have, or develop, anxiety disorders and who want treatment. This has clear implications for practice and policy for anxiety screening during the perinatal period.

Assessment of perinatal anxiety: diagnostic accuracy of five measures.

BACKGROUND: Anxiety in pregnancy and after giving birth (the perinatal period) is highly prevalent but under-recognised. Robust methods of assessing perinatal anxiety are essential for services to identify and treat women appropriately. AIMS: To determine which assessment measures are most psychometrically robust and effective at identifying women with perinatal anxiety (primary objective) and depression (secondary objective). METHOD: We conducted a prospective longitudinal cohort study of 2243 women who completed five measures of anxiety and depression (Generalized Anxiety Disorder scale (GAD) two- and seven-item versions; Whooley questions; Clinical Outcomes in Routine Evaluation (CORE-10); and Stirling Antenatal Anxiety Scale (SAAS)) during pregnancy (15 weeks, 22 weeks and 31 weeks) and after birth (6 weeks). To assess diagnostic accuracy a sample of 403 participants completed modules of the Mini-International Neuropsychiatric Interview (MINI). RESULTS: The best diagnostic accuracy for anxiety was shown by the CORE-10 and SAAS. The best diagnostic accuracy for depression was shown by the CORE-10, SAAS and Whooley questions, although the SAAS had lower specificity. The same cut-off scores for each measure were optimal for identifying anxiety or depression (SAAS ≥9; CORE-10 ≥9; Whooley ≥1). All measures were psychometrically robust, with good internal consistency, convergent validity and unidimensional factor structure. CONCLUSIONS: This study identified robust and effective methods of assessing perinatal anxiety and depression. We recommend using the CORE-10 or SAAS to assess perinatal anxiety and the CORE-10 or Whooley questions to assess depression. The GAD-2 and GAD-7 did not perform as well as other measures and optimal cut-offs were lower than currently recommended.

Evolution of antigen-specific follicular helper T cell transcription from effector function to memory.

Understanding how follicular helper T cells (TFH) regulate the specialization, maturation, and differentiation of adaptive B cell immunity is crucial for developing durable high-affinity immune protection. Using indexed single-cell molecular strategies, we reveal a skewed intraclonal assortment of higher-affinity T cell receptors and the distinct molecular programming of the localized TFH compartment compared with emigrant conventional effector TH cells. We find a temporal shift in B cell receptor class switch, which permits identification of inflammatory and anti-inflammatory modules of transcriptional programming that subspecialize TFH function before and during the germinal center (GC) reaction. Late collapse of this local primary GC reaction reveals a persistent post-GC TFH population that discloses a putative memory TFH program. These studies define subspecialized antigen-specific TFH transcriptional programs that progressively change with antibody class-specific evolution of high-affinity B cell immunity and a memory TFH transcriptional program that emerges upon local GC resolution.

The experience of fathers during the covid-19 UK maternity care restrictions.

OBJECTIVE: During the COVID-19 pandemic fathers in the UK were excluded from many aspects of maternity care to reduce escalating transmission rates. This study explores the experiences of fathers who had a baby during the pandemic to understand what effect these maternity restrictions had on them and their relationship to the baby. DESIGN: A qualitative interview study of the experiences of fathers whose baby was born during the pandemic-related UK maternity restrictions. PARTICIPANTS AND SETTING: Non-probability voluntary response sampling of 20 fathers: including 13 primiparous fathers and 7 multiparous fathers. Eligibility criteria were that fathers lived in the UK and had a baby born on or after the 23rd March 2020; the start of the most severe COVID-19 maternity restrictions. Participants were interviewed remotely via telephone using semi-structured interviews which were transcribed and analysed using thematic analysis. FINDINGS: Four themes, including ten sub-themes, were identified that described fathers' experiences of the maternity restrictions and the father-baby relationship. The themes were: (1) The impact on paternal experience: this theme describes a collective negative paternal maternity experience as a result of the restrictions. Notably, father exclusion produced feelings of isolation and a sense of loss, along with a disconnection from the pregnancy. (2) The impact on the father-baby relationship: this theme discusses the adverse consequence of the restrictions on initial father-baby bonding. (3) Observed impact on mothers: the observed detrimental impact that excluding fathers had on maternal mental health and well-being. Finally, (4) Fatherhood in the 'new normal': the change of daily living during the pandemic aided profound family relationship building, improving long-term father-baby bonding, compared to pre-pandemic conditions. KEY CONCLUSIONS: The findings provide evidence of undesirable consequences the pandemic-related UK maternity restrictions had on birth partners. With restrictions to maternity care implemented across the globe, these concerns may be applicable at an international scale. IMPLICATIONS FOR PRACTICE: This study adds to other contemporary literature on this subject and can inform discussion among maternity services of the importance of including fathers for improved parental well-being and initial infant bonding.

Isotype-specific plasma cells express divergent transcriptional programs.

Antibodies are produced across multiple isotypes with distinct properties that coordinate initial antigen clearance and confer long-term antigen-specific immune protection. Here, we interrogate the molecular programs of isotype-specific murine plasma cells (PC) following helper T cell-dependent immunization and within established steady-state immunity. We developed a single-cell-indexed and targeted molecular strategy to dissect conserved and divergent components of the rapid effector phase of antigen-specific IgM+ versus inflammation-modulating programs dictated by type 1 IgG2a/b+ PC differentiation. During antibody affinity maturation, the germinal center (GC) cycle imparts separable programs for post-GC type 2 inhibitory IgG1+ and type 1 inflammatory IgG2a/b+ PC to direct long-term cellular function. In the steady state, two subsets of IgM+ and separate IgG2b+ PC programs clearly segregate from splenic type 3 IgA+ PC programs that emphasize mucosal barrier protection. These diverse isotype-specific molecular pathways of PC differentiation control complementary modules of antigen clearance and immune protection that could be selectively targeted for immunotherapeutic applications and vaccine design.

Precision rehabilitation for aphasia by patient age, sex, aphasia severity, and time since stroke? A prespecified, systematic review-based, individual participant data, network, subgroup meta-analysis.

BACKGROUND: Stroke rehabilitation interventions are routinely personalized to address individuals' needs, goals, and challenges based on evidence from aggregated randomized controlled trials (RCT) data and meta-syntheses. Individual participant data (IPD) meta-analyses may better inform the development of precision rehabilitation approaches, quantifying treatment responses while adjusting for confounders and reducing ecological bias. AIM: We explored associations between speech and language therapy (SLT) interventions frequency (days/week), intensity (h/week), and dosage (total SLT-hours) and language outcomes for different age, sex, aphasia severity, and chronicity subgroups by undertaking prespecified subgroup network meta-analyses of the RELEASE database. METHODS: MEDLINE, EMBASE, and trial registrations were systematically searched (inception-Sept2015) for RCTs, including ⩾ 10 IPD on stroke-related aphasia. We extracted demographic, stroke, aphasia, SLT, and risk of bias data. Overall-language ability, auditory comprehension, and functional communication outcomes were standardized. A one-stage, random effects, network meta-analysis approach filtered IPD into a single optimal model, examining SLT regimen and language recovery from baseline to first post-intervention follow-up, adjusting for covariates identified a-priori. Data were dichotomized by age (⩽/> 65 years), aphasia severity (mild-moderate/ moderate-severe based on language outcomes' median value), chronicity (⩽/> 3 months), and sex subgroups. We reported estimates of means and 95% confidence intervals. Where relative variance was high (> 50%), results were reported for completeness. RESULTS: 959 IPD (25 RCTs) were analyzed. For working-age participants, greatest language gains from baseline occurred alongside moderate to high-intensity SLT (functional communication 3-to-4 h/week; overall-language and comprehension > 9 h/week); older participants' greatest gains occurred alongside low-intensity SLT (⩽ 2 h/week) except for auditory comprehension (> 9 h/week). For both age-groups, SLT-frequency and dosage associated with best language gains were similar. Participants ⩽ 3 months post-onset demonstrated greatest overall-language gains for SLT at low intensity/moderate dosage (⩽ 2 SLT-h/week; 20-to-50 h); for those > 3 months, post-stroke greatest gains were associated with moderate-intensity/high-dosage SLT (3-4 SLT-h/week; ⩾ 50 hours). For moderate-severe participants, 4 SLT-days/week conferred the greatest language gains across outcomes, with auditory comprehension gains only observed for ⩾ 4 SLT-days/week; mild-moderate participants' greatest functional communication gains were associated with similar frequency (⩾ 4 SLT-days/week) and greatest overall-language gains with higher frequency SLT (⩾ 6 days/weekly). Males' greatest gains were associated with SLT of moderate (functional communication; 3-to-4 h/weekly) or high intensity (overall-language and auditory comprehension; (> 9 h/weekly) compared to females for whom the greatest gains were associated with lower-intensity SLT (< 2 SLT-h/weekly). Consistencies across subgroups were also evident; greatest overall-language gains were associated with 20-to-50 SLT-h in total; auditory comprehension gains were generally observed when SLT > 9 h over ⩾ 4 days/week. CONCLUSIONS: We observed a treatment response in most subgroups' overall-language, auditory comprehension, and functional communication language gains. For some, the maximum treatment response varied in association with different SLT-frequency, intensity, and dosage. Where differences were observed, working-aged, chronic, mild-moderate, and male subgroups experienced their greatest language gains alongside high-frequency/intensity SLT. In contrast, older, moderate-severely impaired, and female subgroups within 3 months of aphasia onset made their greatest gains for lower-intensity SLT. The acceptability, clinical, and cost effectiveness of precision aphasia rehabilitation approaches based on age, sex, aphasia severity, and chronicity should be evaluated in future clinical RCTs.

Variability of response to early puberty induction demonstrated by transverse uterine diameter measurement and a novel method of 3D breast imaging.

OBJECTIVE: Induction of puberty with exogenous oestrogen results in considerable variability in final uterine and breast volumes. We set out to quantify the variability of these two outcome measures with a view to establishing monitoring methods that could be used to individualise treatment protocols. DESIGN: A prospective observational study. PARTICIPANTS: Sixteen participants with pubertal delay and primary amenorrhoea, due to hypogonadism were recruited from paediatric gynaecology and endocrinology clinics at University College London Hospital. A standardised protocol of transdermal 17ß oestradiol (17ßE) was used (Evorel™), with a starting dose of 12.5 mcg increasing to 25 mcg (patch changed twice weekly) after 4 months. Follow up was every 2 months for a total of 8 months. MEASUREMENTS: Uterine dimensions using ultrasound, oestradiol concentrations and breast development assessed by both Tanner staging and 3D photographic imaging. RESULTS: After 8 months of treatment, the changes in oestradiol concentrations (0-174 pmol), uterine volume growth (4.4-16.4 ml) and breast volume (1.76-140.1 ml) varied greatly between individuals. Of uterine parameters, transverse uterine diameter was most closely associated with serum oestradiol levels at 8 months (beta standardised coefficient = 0.80, p = .001). Change in breast volume was associated with age of treatment initiation (beta standardised coefficient 0.55 p = .04). CONCLUSIONS: We demonstrate variation in response to exogenous oestrogen, emphasising the necessity for individualised dose titration. In the absence of sensitive oestradiol assays, uterine transverse measurements may be used as a surrogate marker of oestrogen sensitivity to guide early dose adjustment. 3D breast imaging may provide a quantitative assessment of breast development to complement Tanner breast staging.

Single cell qtSEQ: Cell-indexed quantitative and targeted RNA sequencing for sorted rare lymphocyte subpopulations.

Adaptive T and B lymphocytes expand, respond, and persist across a multitude of separable cell differentiation states. Small compartments of these cells present defined cell surface phenotype, but express potentially divergent immune functions. Here, we use high resolution flow cytometry to provide direct access to rare lymphocyte subpopulations for evaluation of steady-state or reactive transcriptional programs. We sort and index single cells by phenotype in 384-well format for quantification of targeted gene amplification through RNA sequencing (single cell qtSEQ). For complete details on the use and execution of this profile, please refer to Dufaud et al. (2021).

The SEQC2 epigenomics quality control (EpiQC) study.

BACKGROUND: Cytosine modifications in DNA such as 5-methylcytosine (5mC) underlie a broad range of developmental processes, maintain cellular lineage specification, and can define or stratify types of cancer and other diseases. However, the wide variety of approaches available to interrogate these modifications has created a need for harmonized materials, methods, and rigorous benchmarking to improve genome-wide methylome sequencing applications in clinical and basic research. Here, we present a multi-platform assessment and cross-validated resource for epigenetics research from the FDA's Epigenomics Quality Control Group. RESULTS: Each sample is processed in multiple replicates by three whole-genome bisulfite sequencing (WGBS) protocols (TruSeq DNA methylation, Accel-NGS MethylSeq, and SPLAT), oxidative bisulfite sequencing (TrueMethyl), enzymatic deamination method (EMSeq), targeted methylation sequencing (Illumina Methyl Capture EPIC), single-molecule long-read nanopore sequencing from Oxford Nanopore Technologies, and 850k Illumina methylation arrays. After rigorous quality assessment and comparison to Illumina EPIC methylation microarrays and testing on a range of algorithms (Bismark, BitmapperBS, bwa-meth, and BitMapperBS), we find overall high concordance between assays, but also differences in efficiency of read mapping, CpG capture, coverage, and platform performance, and variable performance across 26 microarray normalization algorithms. CONCLUSIONS: The data provided herein can guide the use of these DNA reference materials in epigenomics research, as well as provide best practices for experimental design in future studies. By leveraging seven human cell lines that are designated as publicly available reference materials, these data can be used as a baseline to advance epigenomics research.

Enzymatic methyl sequencing detects DNA methylation at single-base resolution from picograms of DNA.

Bisulfite sequencing detects 5mC and 5hmC at single-base resolution. However, bisulfite treatment damages DNA, which results in fragmentation, DNA loss, and biased sequencing data. To overcome these problems, enzymatic methyl-seq (EM-seq) was developed. This method detects 5mC and 5hmC using two sets of enzymatic reactions. In the first reaction, TET2 and T4-BGT convert 5mC and 5hmC into products that cannot be deaminated by APOBEC3A. In the second reaction, APOBEC3A deaminates unmodified cytosines by converting them to uracils. Therefore, these three enzymes enable the identification of 5mC and 5hmC. EM-seq libraries were compared with bisulfite-converted DNA, and each library type was ligated to Illumina adaptors before conversion. Libraries were made using NA12878 genomic DNA, cell-free DNA, and FFPE DNA over a range of DNA inputs. The 5mC and 5hmC detected in EM-seq libraries were similar to those of bisulfite libraries. However, libraries made using EM-seq outperformed bisulfite-converted libraries in all specific measures examined (coverage, duplication, sensitivity, etc.). EM-seq libraries displayed even GC distribution, better correlations across DNA inputs, increased numbers of CpGs within genomic features, and accuracy of cytosine methylation calls. EM-seq was effective using as little as 100 pg of DNA, and these libraries maintained the described advantages over bisulfite sequencing. EM-seq library construction, using challenging samples and lower DNA inputs, opens new avenues for research and clinical applications.

Time to take care: fighting HIV with health promotion in Edinburgh, 1983-1996.

During the 1980s and 1990s, Edinburgh and the Lothians suffered significantly high rates of HIV infections, considered to be the result of a high proportion of intravenous drug users sharing injecting equipment. This young, sexually active cohort had the potential to pose a threat to the wider population via heterosexual spread, and hence measures were required to prevent, where possible, a second wave of the epidemic. A coalition of health professionals, local authority groups and voluntary organisations consequently acted by producing a series of health promotional campaigns, such as the 'Take Care' campaign, in order to promote healthy and safe sexual practice and to educate the community about the risks of HIV and AIDS. Many of the strategies utilised by Lothian public bodies were pioneering, using distinctive imagery and novel marketing techniques. Despite aiming these campaigns at the broader community however, campaigns spearheaded by health providers and local government often excluded certain high-risk populations, such as drug users and gay men, and subsequently these demographic groups had to turn to other services (in voluntary, non-governmental sectors) for health education and promotion.

A historical analysis of surgery performed between 1941 and 1942 at the Bangour Maxillofacial and Plastic Surgery Unit, Scotland.

In 1939, Bangour Emergency Medical Services Hospital was built as an annexe to Edinburgh War Hospital. The Maxillofacial and Plastic Surgery Unit opened in 1941, one of the several set-ups built with the support of Sir Harold Gillies, to ensure a service with specialist skills throughout Great Britain. The unit was led by Alexander Burns Wallace, who had to rapidly adapt the service to reflect the patterns of injury reflected by the more modern warfare practiced in the Second World War, while also incorporating techniques that were, at the time, revolutionary. Although much has been written about other units, Bangour's activity revealed through its case histories' highlights that plastic surgery was developing in parallel throughout Britain. The influence of Sir Harold Gillies was clear, and his input to support the fledgling service serves as an important aspect of the newly developing specialty of plastic surgery: collaboration and sharing of knowledge. This paper analyses the work of the Maxillofacial and Plastic Surgery Unit at Bangour General Hospital in Scotland between 1941 and 1942 and demonstrates its historical significance, as well as its relevance to current practice. Ninety-two case notes from the unit recently became accessible. These were analysed and four were selected for review in this study. These cases were selected as they were well-documented with photographs and good examples of the work performed at the unit in order to highlight the innovative, creative and complicated work carried out at the Unit.

Norman Dott (1897-1973) and medical illustration: the importance of art to neurosurgery.

Anatomical information and pathologies have been conveyed through the medium of medical illustrations for centuries. In the formative years of British neurosurgery, Professor Norman Dott (1897-1973) utilised medical illustrations as a means of documenting neurosurgical advances and conveying pathological-anatomical correlation. He commissioned a vast number of medical illustrations over the course of his career, ultimately producing a diverse collection of items, most of which is cared for by Lothian Health Services Archive (LHSA), Edinburgh, Scotland. In this study, the original material from Dott's personal collection was audited. Of 172 stand-alone drawings, 84 were categorised and analysed. The findings are a reflection of Dott's expertise as an academic and a surgeon. Spanning the years 1925-1968, a wide range of pathologies and procedures are depicted including intracranial aneurysms and their ligation, an area in which Dott was renowned for pioneering surgical advances. The collection stands as a testament to Dott's emphasis upon medical illustration to communicate the intricacies and complexities of his field, providing valuable insight into clinical and surgical practice in neurosurgery when the specialty was in its juvenescence. In order to illuminate the connections between biography and specialism that generated an extraordinary visual archive, this study considers the early life and work of Norman Dott and the influence of Harvey Cushing on Dott's prioritisation of visual documentation of surgical practice. It explores the impact of German-American medical artist Max Brödel on the UK, and especially on the artists employed by Dott, before presenting a short review of the medical illustrations they created.

Basic versus biofeedback-mediated intensive pelvic floor muscle training for women with urinary incontinence: the OPAL RCT.

BACKGROUND: Urinary incontinence affects one in three women worldwide. Pelvic floor muscle training is an effective treatment. Electromyography biofeedback (providing visual or auditory feedback of internal muscle movement) is an adjunct that may improve outcomes. OBJECTIVES: To determine the clinical effectiveness and cost-effectiveness of biofeedback-mediated intensive pelvic floor muscle training (biofeedback pelvic floor muscle training) compared with basic pelvic floor muscle training for treating female stress urinary incontinence or mixed urinary incontinence. DESIGN: A multicentre, parallel-group randomised controlled trial of the clinical effectiveness and cost-effectiveness of biofeedback pelvic floor muscle training compared with basic pelvic floor muscle training, with a mixed-methods process evaluation and a longitudinal qualitative case study. Group allocation was by web-based application, with minimisation by urinary incontinence type, centre, age and baseline urinary incontinence severity. Participants, therapy providers and researchers were not blinded to group allocation. Six-month pelvic floor muscle assessments were conducted by a blinded assessor. SETTING: This trial was set in UK community and outpatient care settings. PARTICIPANTS: Women aged ≥ 18 years, with new stress urinary incontinence or mixed urinary incontinence. The following women were excluded: those with urgency urinary incontinence alone, those who had received formal instruction in pelvic floor muscle training in the previous year, those unable to contract their pelvic floor muscles, those pregnant or < 6 months postnatal, those with prolapse greater than stage II, those currently having treatment for pelvic cancer, those with cognitive impairment affecting capacity to give informed consent, those with neurological disease, those with a known nickel allergy or sensitivity and those currently participating in other research relating to their urinary incontinence. INTERVENTIONS: Both groups were offered six appointments over 16 weeks to receive biofeedback pelvic floor muscle training or basic pelvic floor muscle training. Home biofeedback units were provided to the biofeedback pelvic floor muscle training group. Behaviour change techniques were built in to both interventions. MAIN OUTCOME MEASURES: The primary outcome was urinary incontinence severity at 24 months (measured using the International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form score, range 0-21, with a higher score indicating greater severity). The secondary outcomes were urinary incontinence cure/improvement, other urinary and pelvic floor symptoms, urinary incontinence-specific quality of life, self-efficacy for pelvic floor muscle training, global impression of improvement in urinary incontinence, adherence to the exercise, uptake of other urinary incontinence treatment and pelvic floor muscle function. The primary health economic outcome was incremental cost per quality-adjusted-life-year gained at 24 months. RESULTS: A total of 300 participants were randomised per group. The primary analysis included 225 and 235 participants (biofeedback and basic pelvic floor muscle training, respectively). The mean 24-month International Consultation on Incontinence Questionnaire Urinary Incontinence Short Form score was 8.2 (standard deviation 5.1) for biofeedback pelvic floor muscle training and 8.5 (standard deviation 4.9) for basic pelvic floor muscle training (adjusted mean difference -0.09, 95% confidence interval -0.92 to 0.75; p = 0.84). A total of 48 participants had a non-serious adverse event (34 in the biofeedback pelvic floor muscle training group and 14 in the basic pelvic floor muscle training group), of whom 23 (21 in the biofeedback pelvic floor muscle training group and 2 in the basic pelvic floor muscle training group) had an event related/possibly related to the interventions. In addition, there were eight serious adverse events (six in the biofeedback pelvic floor muscle training group and two in the basic pelvic floor muscle training group), all unrelated to the interventions. At 24 months, biofeedback pelvic floor muscle training was not significantly more expensive than basic pelvic floor muscle training, but neither was it associated with significantly more quality-adjusted life-years. The probability that biofeedback pelvic floor muscle training would be cost-effective was 48% at a £20,000 willingness to pay for a quality-adjusted life-year threshold. The process evaluation confirmed that the biofeedback pelvic floor muscle training group received an intensified intervention and both groups received basic pelvic floor muscle training core components. Women were positive about both interventions, adherence to both interventions was similar and both interventions were facilitated by desire to improve their urinary incontinence and hindered by lack of time. LIMITATIONS: Women unable to contract their muscles were excluded, as biofeedback is recommended for these women. CONCLUSIONS: There was no evidence of a difference between biofeedback pelvic floor muscle training and basic pelvic floor muscle training. FUTURE WORK: Research should investigate other ways to intensify pelvic floor muscle training to improve continence outcomes. TRIAL REGISTRATION: Current Controlled Trial ISRCTN57746448.

Urinary incontinence (accidental leakage of urine) is a common and embarrassing problem for women. Pregnancy and childbirth may contribute by leading to less muscle support and bladder control. Pelvic floor exercises and 'biofeedback' equipment (a device that lets women see the muscles working as they exercise) are often used in treatment. There is good evidence that exercises (for the pelvic floor) can help, but less evidence about whether or not adding biofeedback provides better results. This trial compared pelvic floor exercises alone with pelvic floor exercises plus biofeedback. Six hundred women with urinary incontinence participated. Three hundred women were randomly assigned to the exercise group and 300 women were randomised to the exercise plus biofeedback group. Each woman had an equal chance of being in either group. Women were offered six appointments with a therapist over 16 weeks to receive their allocated treatment. After 2 years, there was no difference between the groups in the severity of women's urinary incontinence. Women in both groups varied in how much exercise they managed to do. Some managed to exercise consistently over the 2 years and others less so. There were many factors (other than the treatment received) that affected a woman's ability to exercise. Notably, women viewed the therapists' input very positively. The therapists reported some problems fitting biofeedback into the appointments, but, overall, they delivered both treatments as intended. Women carried out exercises at home and many in the biofeedback pelvic floor muscle training group also used biofeedback at home; however, for both groups, time issues, forgetting and other health problems affected their adherence. There were no serious complications related to either treatment. Overall, exercise plus biofeedback was not significantly more expensive than exercise alone and the quality of life associated with exercise plus biofeedback was not better than the quality of life for exercise alone. In summary, exercises plus biofeedback was no better than exercise alone. The findings do not support using biofeedback routinely as part of pelvic floor exercise treatment for women with urinary incontinence.

Effectiveness of pelvic floor muscle training with and without electromyographic biofeedback for urinary incontinence in women: multicentre randomised controlled trial.

OBJECTIVE: To assess the effectiveness of pelvic floor muscle training (PFMT) plus electromyographic biofeedback or PFMT alone for stress or mixed urinary incontinence in women. DESIGN: Parallel group randomised controlled trial. SETTING: 23 community and secondary care centres providing continence care in Scotland and England. PARTICIPANTS: 600 women aged 18 and older, newly presenting with stress or mixed urinary incontinence between February 2014 and July 2016: 300 were randomised to PFMT plus electromyographic biofeedback and 300 to PFMT alone. INTERVENTIONS: Participants in both groups were offered six appointments with a continence therapist over 16 weeks. Participants in the biofeedback PFMT group received supervised PFMT and a home PFMT programme, incorporating electromyographic biofeedback during clinic appointments and at home. The PFMT group received supervised PFMT and a home PFMT programme. PFMT programmes were progressed over the appointments. MAIN OUTCOME MEASURES: The primary outcome was self-reported severity of urinary incontinence (International Consultation on Incontinence Questionnaire-urinary incontinence short form (ICIQ-UI SF), range 0 to 21, higher scores indicating greater severity) at 24 months. Secondary outcomes were cure or improvement, other pelvic floor symptoms, condition specific quality of life, women's perception of improvement, pelvic floor muscle function, uptake of other urinary incontinence treatment, PFMT self-efficacy, adherence, intervention costs, and quality adjusted life years. RESULTS: Mean ICIQ-UI SF scores at 24 months were 8.2 (SD 5.1, n=225) in the biofeedback PFMT group and 8.5 (SD 4.9, n=235) in the PFMT group (mean difference -0.09, 95% confidence interval -0.92 to 0.75, P=0.84). Biofeedback PFMT had similar costs (mean difference £121 ($154; €133), -£409 to £651, P=0.64) and quality adjusted life years (-0.04, -0.12 to 0.04, P=0.28) to PFMT. 48 participants reported an adverse event: for 23 this was related or possibly related to the interventions. CONCLUSIONS: At 24 months no evidence was found of any important difference in severity of urinary incontinence between PFMT plus electromyographic biofeedback and PFMT alone groups. Routine use of electromyographic biofeedback with PFMT should not be recommended. Other ways of maximising the effects of PFMT should be investigated. TRIAL REGISTRATION: ISRCTN57756448.

RELEASE: a protocol for a systematic review based, individual participant data, meta- and network meta-analysis, of complex speech-language therapy interventions for stroke-related aphasia.

Background: Speech and language therapy (SLT) benefits people with aphasia following stroke. Group level summary statistics from randomised controlled trials hinder exploration of highly complex SLT interventions and a clinically relevant heterogeneous population. Creating a database of individual participant data (IPD) for people with aphasia aims to allow exploration of individual and therapy-related predictors of recovery and prognosis. Aim: To explore the contribution that individual participant characteristics (including stroke and aphasia profiles) and SLT intervention components make to language recovery following stroke. Methods and procedures: We will identify eligible IPD datasets (including randomised controlled trials, non-randomised comparison studies, observational studies and registries) and invite their contribution to the database. Where possible, we will use meta- and network meta-analysis to explore language performance after stroke and predictors of recovery as it relates to participants who had no SLT, historical SLT or SLT in the primary research study. We will also examine the components of effective SLT interventions. Outcomes and results: Outcomes include changes in measures of functional communication, overall severity of language impairment, auditory comprehension, spoken language (including naming), reading and writing from baseline. Data captured on assessment tools will be collated and transformed to a standardised measure for each of the outcome domains. Conclusion: Our planned systematic-review-based IPD meta- and network meta-analysis is a large scale, international, multidisciplinary and methodologically complex endeavour. It will enable hypotheses to be generated and tested to optimise and inform development of interventions for people with aphasia after stroke. Systematic review registration: The protocol has been registered at the International Prospective Register of Systematic Reviews (PROSPERO; registration number: CRD42018110947).

Programming Isotype-Specific Plasma Cell Function.

Helper T cell induced plasma cells (PCs) that secrete class-switched neutralizing antibody are paramount to effective immunity. Following class-switch recombination (CSR), antigen-activated B cells differentiate into extrafollicular PCs or mature in germinal centers (GCs) to produce high-affinity memory B cells and follicular PCs. Many studies focus on the core transcriptional programs that drive central PC functions of longevity and antibody secretion. However, it is becoming clear that these central programs are further subdivided across antibody isotype with separable transcriptional trajectories. Divergent functions emerge at CSR, persist through PC terminal differentiation and further assort memory PC function following antigen recall. Here, we emphasize recent work that assorts divergent isotype-specific PC function across four major modules of immune protection.

Sexual Experience before Treatment for Vaginal Agenesis: A Retrospective Review of 137 Women.

STUDY OBJECTIVE: To summarize the self-reported sexual experiences of women with vaginal agenesis before treatment and discuss the clinical implications. DESIGN: A retrospective review of pretreatment baseline sexuality data and medical records of women with vaginal agenesis seeking vaginal construction. SETTING: A specialist multidisciplinary center for women with genital differences associated with diverse sex development. PARTICIPANTS: One hundred thirty-seven women with untreated vaginal agenesis associated with Mayer-Rokitansky-Küster-Hauser Syndrome and complete androgen insensitivity syndrome aged 15 to 41 years (mean age, 20 years). INTERVENTIONS: Gynecological examination and completion of questionnaires. MAIN OUTCOME MEASURES: (1) Sexual Experiences Questionnaire; (2) Multidimensional Sexuality Questionnaire; (3) Vaginal Self-Perceptions; and (4) vaginal length. RESULTS: A sizable proportion of women reported having had sexually intimate experiences before any medical intervention on the vagina. Vaginal length, which ranged from dimple to 7 cm and averaged 2.7 cm for the cohort, was unrelated to the range of sexual experiences. Most women perceived their vagina as being too small, but less than half believed that a sexual partner would notice this. Two-thirds of the cohort subsequently completed the dilation program, which was not predicted by pretreatment vaginal length or sexual experience. CONCLUSION: Contrary to the assumption that a vagina of certain dimensions is a prerequisite for women to "have sex," many women with Mayer-Rokitansky-Küster-Hauser syndrome and complete androgen insensitivity syndrome reported having experienced genital and nongenital sexual activities with no medical interventions. It is recommended that treatment providers affirm women's capacity for sexual intimacy, relationships, and enjoyment before they introduce the topic of vaginal construction as a non-urgent choice.
