Medication adherence for people with acquired communication disorders: A systematic review.

Conditions such as stroke, dementia and neurodegeneration are major contributors to the incidence of acquired communication disorders in Europe. Pharmacological interventions play a central role in the management and treatment of these conditions, though many patients with an acquired communication disorder may be at a higher risk of medication non-adherence than their peers. The objectives of the current review were to identify, in the context of people with acquired communication disorders: factors that influence medication adherence; current interventions targeting medication adherence; and current measures of medication adherence. This study was conducted and reported in accordance with both PRISMA and SWiM guidelines. Two authors independently screened the results of a literature search, assessed risk of bias and extracted relevant data. Eight studies were identified for inclusion. The results of this review indicate that patient-related factors are most indicative of medication non-adherence in a population with acquired communication disorders, followed by socioeconomic factors and medication-related factors. Despite the recognized importance of medication adherence, no gold standard of assessment or intervention currently exists for this population. Half of the included studies replaced patients with communication difficulties with caregiver proxies, thus reducing opportunities for patients to have agency over their own healthcare. The term "acquired communication disorders" encompasses a range of conditions with diverse aetiologies, presentations and needs, and future research should be tailored to specific patient groups most at risk of medication non-adherence, namely those with aphasia and cognitive-communication impairments. Patients should be empowered to participate in future research to ensure the literature accurately represents their lived experience.

Measuring communication as a core outcome in aphasia trials: Results of the ROMA-2 international core outcome set development meeting.

BACKGROUND: Evidence-based recommendations for a core outcome set (COS; minimum set of outcomes) for aphasia treatment research have been developed (the Research Outcome Measurement in Aphasia-ROMA, COS). Five recommended core outcome constructs: communication, language, quality of life, emotional well-being and patient-reported satisfaction/impact of treatment, were identified through three international consensus studies. Constructs were paired with outcome measurement instruments (OMIs) during an international consensus meeting (ROMA-1). Before the current study (ROMA-2), agreement had not been reached on OMIs for the constructs of communication or patient-reported satisfaction/impact of treatment. AIM: To establish consensus on a communication OMI for inclusion in the ROMA COS. METHODS & PROCEDURES: Research methods were based on recommendations from the Core Outcome Measures in Effectiveness Trials (COMET) Initiative. Participants with expertise in design and conduct of aphasia trials, measurement instrument development/testing and/or communication outcome measurement were recruited through an open call. Before the consensus meeting, participants agreed on a definition of communication, identified appropriate OMIs, extracted their measurement properties and established criteria for their quality assessment. During the consensus meeting they short-listed OMIs and participants without conflicts of interest voted on the two most highly ranked instruments. Consensus was defined a priori as agreement by ≥ 70% of participants. OUTCOMES & RESULTS: In total, 40 researchers from nine countries participated in ROMA-2 (including four facilitators and three-panel members who participated in pre-meeting activities only). A total of 20 OMIs were identified and evaluated. Eight short-listed communication measures were further evaluated for their measurement properties and ranked. Participants in the consensus meeting (n = 33) who did not have conflicts of interest (n = 29) voted on the top two ranked OMIs: The Scenario Test (TST) and the Communication Activities of Daily Living-3 (CADL-3). TST received 72% (n = 21) of 'yes' votes and the CADL-3 received 28% (n = 8) of 'yes' votes. CONCLUSIONS & IMPLICATIONS: Consensus was achieved that TST was the preferred communication OMI for inclusion in the ROMA COS. It is currently available in the original Dutch version and has been adapted into English, German and Greek. Further consideration must be given to the best way to measure communication in people with mild aphasia. Development of a patient-reported measure for satisfaction with/impact of treatment and multilingual versions of all OMIs of the COS is still required. Implementation of the ROMA COS would improve research outcome measurement and the quality, relevance, transparency, replicability and efficiency of aphasia treatment research. WHAT THIS PAPER ADDS: What is already known on this subject International consensus has been reached on five core constructs to be routinely measured in aphasia treatment studies. International consensus has also been established for OMIs for the three constructs of language, quality of life and emotional well-being. Before this study, OMIs for the constructs of communication and patient-reported satisfaction/impact of treatment were not established. What this paper adds to existing knowledge We gained international consensus on an OMI for the construct of communication. TST is recommended for inclusion in the ROMA COS for routine use in aphasia treatment research. What are the potential or actual clinical implications of this work? The ROMA COS recommends OMIs for a minimum set of outcomes for adults with post-stroke aphasia within phases I-IV aphasia treatment research. Although not intended for clinical use, clinicians may employ the instruments of the ROMA COS, considering the quality of their measurement properties. The systematic inclusion of a measure of communication, such as TST, in clinical practice could ultimately support the implementation of research evidence and best practices.

Developing a simulation tool to quantify biomechanical load and quality of care in nursing.

Nursing is a high musculoskeletal disorder (MSD) risk job with high workload demands. This study combines Digital Human Modelling (DHM) and Discrete Event Simulation (DES) to address the need for tools to better manage MSD risk. This novel approach quantifies physical-workload, work-performance, and quality-of-care, in response to varying geographical patient-bed assignments, patient-acuity levels, and nurse-patient ratios. Lumbar loads for 86 care-delivery tasks in an acute care hospital unit were used as inputs in a DES model of the care-delivery process, creating a shift-long time trace of the biomechanical load. Peak L4/L5 compression and moment were 3574 N and 111.58 Nm, respectively. This study reports trade-offs in all three experiments: (i) increasing geographical patient-bed assignment distance decreased L4/L5 compression (8.8%); (ii) increased patient-acuity decreased L4/L5 moment (4%); (iii) Increased nurse-patient ratio decreased L4/L5 compression (10%) and moment (17%). However, in all experiments, Quality of care indicators deteriorated (20, 19, and 29%, respectively).Practitioner Summary: This research has the potential to support decision-makers by developing a simulation tool that quantifies the impact of varying operational and design-policies in terms of biomechanical-load and quality of care. The demonstrator-model reports: as geographical patient-bed distance, patient-acuity levels, and nurse-patient ratios increase, biomechanical-load reduces, and quality of care deteriorates.

Psychosocial and supportive care needs of individuals with advanced myeloma.

Purpose: The purpose of this qualitative study is to understand, from the patient's perspective, their experience of living with advanced multiple myeloma, the psychosocial impact, and needs for support in managing and adapting to this illness. Methods: An interpretive descriptive approach was used. Individual semi-structured telephone interviews were conducted with each participant, which focused on eliciting their descriptions of psychosocial issues and concerns, as well as the supports they use for coping with cancer. Transcripts were analyzed using interpretive description, resulting in the generation of common themes that represented the data. Results: The sample comprised twelve adults with a diagnosis of advanced multiple myeloma who had undergone at least three lines of treatment or were transfusion dependent. All participants were receiving ambulatory care for their myeloma in Toronto, Ontario, Canada. Four themes were generated: (1) confusion about the diagnosis and treatment options; (2) challenges in finding relevant information; (3) dealing with the chronicity of treatment side effects; (4) social support as critical for coping with the life-threat of multiple myeloma. Conclusion: Findings suggest that the psychosocial impact of living with advanced multiple myeloma is greatly impacted by one's ability to understand the complexities of the diagnosis and access supports to cope with its physical and emotional consequences. Clinical interventions specifically tailored to meeting the information and support needs of this population are needed.

The development of "automated visual evaluation" for cervical cancer screening: The promise and challenges in adapting deep-learning for clinical testing: Interdisciplinary principles of automated visual evaluation in cervical screening.

There is limited access to effective cervical cancer screening programs in many resource-limited settings, resulting in continued high cervical cancer burden. Human papillomavirus (HPV) testing is increasingly recognized to be the preferable primary screening approach if affordable due to superior long-term reassurance when negative and adaptability to self-sampling. Visual inspection with acetic acid (VIA) is an inexpensive but subjective and inaccurate method widely used in resource-limited settings, either for primary screening or for triage of HPV-positive individuals. A deep learning (DL)-based automated visual evaluation (AVE) of cervical images has been developed to help improve the accuracy and reproducibility of VIA as assistive technology. However, like any new clinical technology, rigorous evaluation and proof of clinical effectiveness are required before AVE is implemented widely. In the current article, we outline essential clinical and technical considerations involved in building a validated DL-based AVE tool for broad use as a clinical test.

Diagnostic accuracy of cervical cancer screening and screening-triage strategies among women living with HIV-1 in Burkina Faso and South Africa: A cohort study.

BACKGROUND: Cervical cancer screening strategies using visual inspection or cytology may have suboptimal diagnostic accuracy for detection of precancer in women living with HIV (WLHIV). The optimal screen and screen-triage strategy, age to initiate, and frequency of screening for WLHIV remain unclear. This study evaluated the sensitivity, specificity, and positive predictive value of different cervical cancer strategies in WLHIV in Africa. METHODS AND FINDINGS: WLHIV aged 25-50 years attending HIV treatment centres in Burkina Faso (BF) and South Africa (SA) from 5 December 2011 to 30 October 2012 were enrolled in a prospective evaluation study of visual inspection using acetic acid (VIA) or visual inspection using Lugol's iodine (VILI), high-risk human papillomavirus DNA test (Hybrid Capture 2 [HC2] or careHPV), and cytology for histology-verified high-grade cervical intraepithelial neoplasia (CIN2+/CIN3+) at baseline and endline, a median 16 months later. Among 1,238 women (BF: 615; SA: 623), median age was 36 and 34 years (p < 0.001), 28.6% and 49.6% ever had prior cervical cancer screening (p < 0.001), and 69.9% and 64.2% were taking ART at enrolment (p = 0.045) in BF and SA, respectively. CIN2+ prevalence was 5.8% and 22.4% in BF and SA (p < 0.001), respectively. VIA had low sensitivity for CIN2+ (44.7%, 95% confidence interval [CI] 36.9%-52.7%) and CIN3+ (56.1%, 95% CI 43.3%-68.3%) in both countries, with specificity for ≤CIN1 of 78.7% (95% CI 76.0%-81.3%). HC2 had sensitivity of 88.8% (95% CI 82.9%-93.2%) for CIN2+ and 86.4% (95% CI 75.7%-93.6%) for CIN3+. Specificity for ≤CIN1 was 55.4% (95% CI 52.2%-58.6%), and screen positivity was 51.3%. Specificity was higher with a restricted genotype (HPV16/18/31/33/35/45/52/58) approach (73.5%, 95% CI 70.6%-76.2%), with lower screen positivity (33.7%), although there was lower sensitivity for CIN3+ (77.3%, 95% CI 65.3%-86.7%). In BF, HC2 was more sensitive for CIN2+/CIN3+ compared to VIA/VILI (relative sensitivity for CIN2+ = 1.72, 95% CI 1.28-2.32; CIN3+: 1.18, 95% CI 0.94-1.49). Triage of HC2-positive women with VIA/VILI reduced the number of colposcopy referrals, but with loss in sensitivity for CIN2+ (58.1%) but not for CIN3+ (84.6%). In SA, cytology high-grade squamous intraepithelial lesion or greater (HSIL+) had best combination of sensitivity (CIN2+: 70.1%, 95% CI 61.3%-77.9%; CIN3+: 80.8%, 95% CI 67.5%-90.4%) and specificity (81.6%, 95% CI 77.6%-85.1%). HC2 had similar sensitivity for CIN3+ (83.0%, 95% CI 70.2%-91.9%) but lower specificity compared to HSIL+ (42.7%, 95% CI 38.4%-47.1%; relative specificity = 0.57, 95% CI 0.52-0.63), resulting in almost twice as many referrals. Compared to HC2, triage of HC2-positive women with HSIL+ resulted in a 40% reduction in colposcopy referrals but was associated with some loss in sensitivity. CIN2+ incidence over a median 16 months was highest among VIA baseline screen-negative women (2.2%, 95% CI 1.3%-3.7%) and women who were baseline double-negative with HC2 and VIA (2.1%, 95% CI 1.3%-3.5%) and lowest among HC2 baseline screen-negative women (0.5%, 95% CI 0.1%-1.8%). Limitations of our study are that WLHIV included in the study may not reflect a contemporary cohort of WLHIV initiating ART in the universal ART era and that we did not evaluate HPV tests available in study settings today. CONCLUSIONS: In this cohort study among WLHIV in Africa, a human papillomavirus (HPV) test targeting 14 high-risk (HR) types had higher sensitivity to detect CIN2+ compared to visual inspection but had low specificity, although a restricted genotype approach targeting 8 HR types decreased the number of unnecessary colposcopy referrals. Cytology HSIL+ had optimal performance for CIN2+/CIN3+ detection in SA. Triage of HPV-positive women with HSIL+ maintained high specificity but with some loss in sensitivity compared to HC2 alone.

Antiretroviral Therapy and Detection of High-grade Cervical Intraepithelial Neoplasia (CIN2+) at Post-CIN Management Follow-up Among Women Living With Human Immunodeficiency Virus: A Systematic Review and Meta-Analysis.

BACKGROUND: We evaluated the association of antiretroviral therapy (ART), CD4+ count and human immunodeficiency virus (HIV) plasma viral load (PVL) on high-grade cervical intraepithelial neoplasia (CIN2+) detection at follow-up after CIN management among women living with HIV (WLHIV). METHODS: Medline, Embase, Global Health, and PubMed were searched from 1 January 1996 to 15 January 2020. Eligible studies investigated the association of ART, CD4+ count, or HIV PVL on histology-confirmed CIN2+ detection at follow-up. Summary estimates were obtained using random-effects meta-analyses; heterogeneity was examined using I2 statistic. PROSPERO registration: CRD42018115631. RESULTS: Eight studies representing 9 populations were identified, including 1452 WLHIV followed between 6 and 33 months post-CIN management. Pooled data from 8 populations (n = 1408) suggested weak evidence of a decreased risk of CIN2+ detection at follow-up among ART users compared to ART-naive women (crude odds ratio [cOR] = 0.70, 95% confidence interval [CI]: .36-1.36; I2 = 64.5%, P = .006; adjusted risk ratio [aRR] from 3 studies = 0.66, 95% CI: .20-2.24; I2 = 78.7%, P = .009). A significant association was observed in high-income countries (cOR = 0.24, 95% CI: .13-.45; I2 = 0.0%, P = .77) but not in low and middle-income countries (cOR = 1.13, 95% CI: .67-1.92; I2 = 18.8%, P = .30).In 3 populations, ART users with HIV PVL <50 copies/ml were less likely to have CIN2+ detection at follow-up (vs ≥50 copies/mL: cOR = 0.55, 95% CI: .32-.94; I2 = 0.0%, P = .23).There was weak evidence of decreased CIN2+ detection at follow-up among WLHIV with higher contemporary CD4+ cell counts (≥200 cells/µL vs <200 cells/µL [cOR = 0.36, 95% CI: .04-3.13; I2 = 81.3%, P = .021]) and significant evidence among women with a higher nadir CD4+ count (≥350 cells/µl vs <200 cells/µl [adjusted hazard ratio [aHR] = 0.35, 95% CI: .15-.84; I2 = 0%, P = .64]). CONCLUSION: ART may reduce the risk of CIN2+ detection at follow-up; this effect is most likely enhanced by a combination of adequate HIV control and excisional CIN treatment. Our findings support recommendations of early ART and the integration of CIN2+ screening and management into HIV care.

'This is your golden time. You enjoy it and you've plenty time for crying after': How dysphagia impacts family caregivers of people with amyotrophic lateral sclerosis - A qualitative study.

BACKGROUND: Dysphagia (swallowing impairments) is a well-recognised symptom of amyotrophic lateral sclerosis. Caring for a person with amyotrophic lateral sclerosis has been recognised as a complex and demanding task. No study to date investigated the impact of dysphagia on the lives of caregivers of people with amyotrophic lateral sclerosis. AIM: To investigate the experiences of dysphagia from the perspective of family caregivers of people diagnosed with amyotrophic lateral sclerosis. DESIGN: Interpretative phenomenological analysis was employed. Individual interviews (n = 15) plus observations of mealtime preparation were conducted, where possible (seven or n). SETTING/PARTICIPANTS: Participants comprised family caregivers of people with amyotrophic lateral sclerosis and dysphagia living in the South West of Ireland (n = 10). FINDINGS: Dysphagia transformed the mealtime experiences of the caregivers and changed their approaches to food. Frustration related to the inability to stabilise the weight of the person with amyotrophic lateral sclerosis and the fear of choking emerged strongly. The caregivers strived to ensure the safety of people with amyotrophic lateral sclerosis during meals by providing constant supervision. Despite the challenges precipitated by dysphagia and amyotrophic lateral sclerosis, the caregivers wished to maintain normality for as long as they perceived it to be possible. CONCLUSION: This study provides a unique contribution in advancing our understanding of the impact of dysphagia on the caregivers of people with amyotrophic lateral sclerosis. Professionals must explore and recognise the needs of the caregivers and provide them with appropriate support, especially how to manage choking.

Immunogenetics in stem cell donor registry work: The DKMS example (Part 2).

DKMS is a leading stem cell donor registry with more than 9 million donors. Donor registry activities share many touch points with topics from immunogenetics or population genetics. In this two-part review article, we deal with these aspects of donor registry work by using the example of DKMS. In the second part of the review, we focus on donor typing of non-HLA genes, the impact of donor age, gender and CMV serostatus on donation probabilities, the identification of novel HLA, KIR and MIC alleles by high-throughput donor typing, the activities of the Collaborative Biobank and pharmacogenetics in the donor registry context.

Immunogenetics in stem cell donor registry work: The DKMS example (Part 1).

Currently, stem cell donor registries include more than 35 million potential donors worldwide to provide HLA-matched stem cell products for patients in need of an unrelated donor transplant. DKMS is a leading stem cell donor registry with more than 9 million donors from Germany, Poland, the United States, the United Kingdom, India and Chile. DKMS donors have donated hematopoietic stem cells more than 80,000 times. Many aspects of donor registry work are closely related to topics from immunogenetics or population genetics. In this two-part review article, we describe, analyse and discuss these areas of donor registry work by using the example of DKMS. Part 1 of the review gives a general overview on DKMS and includes typical donor registry activities with special focus on the HLA system: high-throughput HLA typing of potential stem cell donors, HLA haplotype frequencies and resulting matching probabilities, and donor file optimization with regard to HLA diversity.

Prevalence and Antimicrobial Resistance of Mycoplasma genitalium Infection Among Women Living With Human Immunodeficiency Virus in South Africa: A Prospective Cohort Study.

This prospective cohort study of 622 women living with human immunodeficiency virus (HIV) from Johannesburg (2012) detected Mycoplasma genitalium in 7.4% (95% confidence interval [CI]: 5.5-9.7, 46/622), with detection more likely with lower CD4 counts(adjusted odds ratio [AOR] 1.02 per 10 cells/µL decrease, 95% CI: 1.00-1.03) and higher plasma HIV-1 RNA (AOR 1.15 per log copies/mL increase, 95% CI: 1.03-1.27). No mutations for macrolide/quinolone resistance was detected.

Performance of DNA methylation assays for detection of high-grade cervical intraepithelial neoplasia (CIN2+): a systematic review and meta-analysis.

BACKGROUND: To conduct a meta-analysis of performance of DNA methylation in women with high-grade cervical intraepithelial neoplasia (CIN2+). METHODS: Medline and Embase databases were searched for studies of methylation markers versus histological endpoints. Pooled sensitivity, specificity and positive predictive value (PPV) for CIN2+ were derived from bivariate models. Relative sensitivity and specificity for CIN2+ compared to cytology and HPV16/18 genotyping were pooled using random-effects models. RESULTS: Sixteen thousand three hundred thirty-six women in 43 studies provided data on human genes (CADM1, MAL, MIR-124-2, FAM19A4, POU4F3, EPB41L3, PAX1, SOX1) and HPV16 (L1/L2). Most (81%) studies evaluated methylation assays following a high-risk (HR)-HPV-positive or abnormal cytology result. Pooled CIN2+ and CIN3+ prevalence was 36.7% and 21.5%. For a set specificity of 70%, methylation sensitivity for CIN2+ and CIN3+ were 68.6% (95% CI: 62.9-73.8) and 71.1% (95% CI: 65.7-76.0) and PPV were 53.4% (95% CI: 44.4-62.1) and 35.0% (95% CI: 28.9-41.6). Among HR-HPV+ women, the relative sensitivity of methylation for CIN2+ was 0.81 (95% CI: 0.63-1.04) and 1.22 (95% CI: 1.05-1.42) compared to cytology of atypical squamous cells of undetermined significance, or greater (ASCUS+) and HPV16/18 genotyping, respectively, while relative specificity was 1.25 (95% CI: 0.99-1.59) and 1.03 (95% CI: 0.94-1.13), respectively. CONCLUSION: DNA methylation is significantly higher in CIN2+ and CIN3+ compared to ≤CIN1. As triage test, DNA methylation has higher specificity than cytology ASCUS+ and higher sensitivity than HPV16/18 genotyping.

Clinical Characteristics of Mycoplasma genitalium and the Usefulness of Syndromic Management Among Women Living With Human Immunodeficiency Virus.

We report the clinical symptoms and examination findings of Mycoplasma genitalium (MG) in women living with human immunodeficiency virus in South Africa. If we relied on syndromic management alone to treat MG, only 15 of 46 MG-infected women would have received. appropriate treatment: sensitivity of 32.6% (95% confidence interval, 19.5-48.0) and specificity of 67.4% (95% confidence interval, 63.4-71.2).

Human Papillomavirus Serology Among Women Living With HIV: Type-Specific Seroprevalence, Seroconversion, and Risk of Cervical Reinfection.

Background: Human papillomavirus (HPV) serodynamics following infection has never been evaluated prospectively among women living with HIV (WLHIV). We determined HPV seroprevalence, seroconversion, and cervical HPV-DNA acquisition among WLHIV. Methods: Prospective study of 604 WLHIV in Johannesburg, South Africa aged 25-50 years. At baseline and 16 months (endline), HPV type-specific antibodies (HPV6/11/16/18/31/33/35/39/45/52/56/58/59/68/73) were measured using HPV-pseudovirions and cervical HPV-DNA genotypes using INNO-LiPA. Results: Seroprevalence of any-HPV was 93.2% and simultaneous seropositivity for HPV types of the bivalent (HPV16/18), quadrivalent (HPV6/11/16/18), and nonavalent (HPV6/11/16/18/31/33/45/52/58) vaccines were 21.4%, 10.9%, and 2.8%. Among 219 women with cervical HPV-DNA, same-type seronegative and without high-grade cervical intraepithelial neoplasia at baseline, 51 (23.3%) had type-specific seroconversion at endline. Risk of type-specific seroconversion was higher among recent antiretroviral therapy users (ART ≤2 years vs ART naive: adjusted OR [aOR] = 2.39; 95% CI, 1.02-5.62), and lower among women with low CD4+ at endline (≤350 vs >350 cells/mm3: aOR = 0.51; 95% CI, 0.24-1.07). Risk of cervical HPV-DNA acquisition was lower in women seropositive for HPV18, 35, and 58 at baseline. Conclusion: WLHIV have evidence of seroconversion in response to baseline HPV-DNA, dependent on CD4+ count and ART. Baseline HPV seropositivity confers limited protection against some HPV types.

Overcoming Challenges to Support Clinician-Scientist Roles in Canadian Academic Health Sciences Centres.

Clinician-scientists (CSs) make significant contributions to the healthcare system, yet their roles are not fully understood, supported or recognized by healthcare leaders or policy makers. CSs are healthcare professionals with advanced research training who continue to pursue clinical work and are considered an essential component of the research infrastructure in academic health sciences centres. The current literature supports the role of CSs but is also clear that there are multiple challenges in attracting and retaining clinicians to the role. To gain a comprehensive understanding of the current status of the CS role, two literature reviews were conducted. The findings reported here include an overview of: the education and training preparation for CS roles; the importance of the CS role; barriers and challenges to developing and implementing the CS role; and strategies for supporting and sustaining CS roles in practice. The paper further describes one Canadian academic health sciences centre's approach to supporting and increasing the number of CSs from nursing and allied health professions to support academic practice. Non-physician CSs may conduct research using multiple research designs across the research continuum from randomized controlled trials to grounded theory or qualitative descriptive approaches. Their research generally focuses on practice-based issues such as best practices for managing pain or frailty or evaluating the effectiveness of new approaches to care. Researchers and healthcare leaders in other organizations may find this work helpful for establishing their own structures to enhance research capacity and practice-based research, especially for non-physician CSs.

Attention control comparisons with SLT for people with aphasia following stroke: methodological concerns raised following a systematic review.

OBJECTIVE: Attention control comparisons in trials of stroke rehabilitation require care to minimize the risk of comparison choice bias. We compared the similarities and differences in SLT and social support control interventions for people with aphasia. DATA SOURCES: Trial data from the 2016 Cochrane systematic review of SLT for aphasia after stroke Methods: Direct and indirect comparisons between SLT, social support and no therapy controls. We double-data extracted intervention details using the template for intervention description and replication. Standardized mean differences and risk ratios (95% confidence intervals (CIs)) were calculated. RESULTS: Seven trials compared SLT with social support ( n = 447). Interventions were matched in format, frequency, intensity, duration and dose. Procedures and materials were often shared across interventions. Social support providers received specialist training and support. Targeted language rehabilitation was only described in therapy interventions. Higher drop-out ( P = 0.005, odds ratio (OR) 0.51, 95% CI 0.32-0.81) and non-adherence to social support interventions ( P < 0.00001, OR 0.18, 95% CI 0.09-0.37) indicated an imbalance in completion rates increasing the risk of control comparison bias. CONCLUSION: Distinctions between social support and therapy interventions were eroded. Theoretically based language rehabilitation was the remaining difference in therapy interventions. Social support is an important adjunct to formal language rehabilitation. Therapists should continue to enable those close to the person with aphasia to provide tailored communication support, functional language stimulation and opportunities to apply rehabilitation gains. Systematic group differences in completion rates is a design-related risk of bias in outcomes observed.

A systematic review and meta-analysis of studies evaluating the performance of point-of-care tests for human papillomavirus screening.

BACKGROUND: High-risk human papillomavirus (HPV) is a necessary cause of high-grade cervical intraepithelial neoplasia (grade 2 or higher, CIN2+). Simplified and rapid HPV DNA assays designed for use in resource-limited settings have recently become available. METHODS: We performed a systematic review and meta-analysis by searching Medline, Embase, Global Health and CINAHL databases for studies from 1 January 2004 to 25 February 2017 that reported the performance of careHPV or OncoE6 for the detection of histological CIN2+ in cervical cancer screening. We used bivariate models to estimate pooled sensitivity and specificity for CIN2+ and CIN3+. RESULTS: A total of 29 657 women were included from seven studies evaluating the performance of careHPV for the detection of CIN2+ and four studies among 27 845 women for the detection of CIN3+. The pooled prevalence for CIN2+ and CIN3+ was 2.3% and 1.1%, respectively. careHPV had sensitivity and specificity of 88.1% (95% CI 81.4 to 92.7) and 83.7% (95% CI 74.9 to 89.8), respectively, for CIN2+ and 90.3% (95% CI 83.4 to 94.5) and 85.3% (95% CI 73.1 to 92.5), respectively, for CIN3+, using clinician-collected cervical specimen. The corresponding pooled estimates using self-collected vaginal swabs were 73.6% (95% CI 64.9 to 80.8) and 88.0% (95% CI 79.1 to 93.5) for CIN2+ and 75.2% (95% CI 66.8 to 82.0) and 90.6% (95% CI 83.4 to 94.9) for CIN3+. Two studies using OncoE6 reported sensitivity and specificity ranging from 31.3% to 42.4% and 99.1%-99.4% for CIN2+, and 53.5% and 98.9% for CIN3+ for one study. CONCLUSION: CareHPV has good sensitivity and specificity for the detection of CIN2+ and CIN3+, but sensitivity was lower using self-collected vaginal samples. The specificity is lower in high HPV prevalence populations such as women living with HIV. OncoE6 assay warrants further evaluation.

Rapid and point-of-care tests for the diagnosis of Trichomonas vaginalis in women and men.

BACKGROUND: Trichomonasvaginalis (TV) is a highly prevalent parasitic infection worldwide. It is associated with many adverse reproductive health outcomes. Many infections are asymptomatic and syndromic management leads to underdetection of TV. Traditional methods of TV detection such as wet preparation are insensitive. New rapid, point-of-care (POC) tests can enhance the diagnosis of trichomoniasis. METHODS: The authors reviewed the literature and discuss older POC tests for TV detection, as well as the OSOM lateral flow test, the AmpliVue test, the Solana test and the GeneXpert test as well as the limitations of wet preparation and culture for detection of TV. RESULTS: The OSOM test is easy to perform, compared with other POC tests, and is Clinical Laboratory Improvement Amendments (CLIA)-waived, equipment-free, has sensitivities of 83%-86% compared with nucleic acid amplification tests (NAATs) and can be performed in 15 min. The AmpliVue and the Solana tests are not CLIA waived and require small pieces of equipment. They are molecular amplified assays and can be completed in <1 hour. AmpliVue demonstrated a sensitivity for vaginal swabs of 100% compared with wet preparation/culture and 90.7% compared with NAATs. Solana demonstrated a sensitivity of 98.6%-100% for vaginal swabs and 92.9%-98% for female urines, compared with wet preparation/culture. Compared with other NAATs, the sensitivity for Solana was 89.7% for swabs and 100% for urine. The GeneXpert TV test for women and men is a moderately complex test, requires a small platform and can be performed in <1 hour. The sensitivity compared with wet preparation/culture for self-collected vaginal swabs was 96.4%, 98.9% for endocervical specimens and 98.4% for female urine. For men, sensitivity for urines was excellent (97.2%). The specificity for all assays was excellent. CONCLUSIONS: Several rapid POC tests have the potential to rapidly diagnose trichomoniasis in women and one is available for detection of TV in men.

Systematic reviews of point-of-care tests for the diagnosis of urogenital Chlamydia trachomatis infections.

BACKGROUND: WHO estimates that 131 million new cases of urogenital Chlamydia trachomatis (CT) infections occur globally every year. Most infections are asymptomatic. Untreated infection in women can lead to severe complications. Screening and treatment of at-risk populations is a priority for prevention and control. OBJECTIVES: To summarise systematic reviews of the performance characteristics of commercially available point-of-care tests (POCT) for screening and diagnosis of urogenital CT infection. METHODS: Two separate systematic reviews covering the periods 2004-2013 and 2010-2015 were conducted on rapid CT POCTs. Studies were included if tests were evaluated against a valid reference standard. RESULTS: In the first review, 635 articles were identified, of which 11 were included. Nine studies evaluated the performance of eight antigen detection rapid POCTs on 10 280 patients and two studies evaluated a near-patient nucleic acid amplification test (NAAT) on 3518 patients. Pooled sensitivity of antigen detection tests was 53%, 37% and 63% for cervical swabs, vaginal swabs and male urine, and specificity was 99%, 97% and 98%, respectively. The pooled sensitivity and specificity of the near-patient NAAT for all specimen types were >98% and 99.4%, respectively. The second review identified two additional studies on four antigen detection POCTs with sensitivities and specificities of 22.7%-37.7% and 99.4%-100%, respectively. A new two-step 15 min rapid POCT using fluorescent nanoparticles showed performance comparable to that of near-patient NAATs. CONCLUSIONS: The systematic reviews showed that antigen detection POCTs for CT, although easy to use, lacked sufficient sensitivity to be recommended as a screening test. A near-patient NAAT shows acceptable performance as a screening or diagnostic test but requires electricity, takes 90 min and is costly. More affordable POCTs are in development.
