Meta-Analysis
Sign language based educational interventions vs. other educational interventions to improve the oral health of hearing-impaired individuals: A systematic review and meta-analysis.
OBJECTIVE
Individuals with special needs requiring special care are more vulnerable to oral health problems. Sign language is a communication medium and language of instruction for individuals with hearing impairments. The purpose of this systematic review and meta-analysis was to assess the effectiveness of sign language-based educational interventions compared to other educational interventions in improving the oral health of hearing-impaired individuals.
METHODS
PubMed, Scopus, Embase, and Cochrane Central Register of Controlled Trials databases were searched without any restriction on the publication date. Analytical and experimental studies that evaluated and compared the effectiveness of sign language with other educational intervention groups such as videos, posters etc were included.
RESULTS
Initially, 5568 records were identified. Three relevant publications from India were eligible and included in the systematic review and meta-analysis. Differences were reported in favour of sign language over other interventions concerning plaque status, gingival health, and oral hygiene status.
CONCLUSION
Sign language-based interventions were found to be effective. However, further studies in different locations and populations are required to support their effectiveness.

UNLABELLED
The objective of this article was to review existing research to assess the evidence for predictive processing (PP) in sign language, the conditions under which it occurs, and the effects of language mastery (sign language as a first language, sign language as a second language, bimodal bilingualism) on the neural bases of PP. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. We searched peer-reviewed electronic databases (SCOPUS, Web of Science, PubMed, ScienceDirect, and EBSCO host) and gray literature (dissertations in ProQuest). We also searched the reference lists of records selected for the review and forward citations to identify all relevant publications. We searched for records based on five criteria (original work, peer-reviewed, published in English, research topic related to PP or neural entrainment, and human sign language processing). To reduce the risk of bias, the remaining two authors with expertise in sign language processing and a variety of research methods reviewed the results. Disagreements were resolved through extensive discussion. In the final review, 7 records were included, of which 5 were published articles and 2 were dissertations. The reviewed records provide evidence for PP in signing populations, although the underlying mechanism in the visual modality is not clear. The reviewed studies addressed the motor simulation proposals, neural basis of PP, as well as the development of PP. All studies used dynamic sign stimuli. Most of the studies focused on semantic prediction. The question of the mechanism for the interaction between one's sign language competence (L1 vs. L2 vs. bimodal bilingual) and PP in the manual-visual modality remains unclear, primarily due to the scarcity of participants with varying degrees of language dominance. There is a paucity of evidence for PP in sign languages, especially for frequency-based, phonetic (articulatory), and syntactic prediction. However, studies published to date indicate that Deaf native/native-like L1 signers predict linguistic information during sign language processing, suggesting that PP is an amodal property of language processing.

Meta-Analysis Review
BACKGROUND
Cervical intradural disc herniation (CIDH) is rare, and diagnosis and treatment are challenging. We conducted a systematic review and meta-analysis of the literature on the diagnosis and treatment of CIDH.
METHOD
The presentation, imaging manifestations, diagnosis, management, prognosis and possible pathogenesis were reviewed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. English-language studies and case reports published from inception to 2017 were retrieved. Data on presentation, imaging characteristics, diagnosis, management, outcomes and pathogenesis were extracted.
RESULTS
Twenty articles involving 23 patients were selected. The most common involved level was C5-6 (43.5%), followed by C6-7 (30.4%), C4-5 (13%), and C3-4 (13%). Spontaneous IDH occurred in 61% of the patients, and relevant cervical trauma was present in 39%. Brown-Sequard's syndrome (56.5%), quadriparesis (34.8%), and radiculopathy (8.7%) were the main presentations. Magnetic resonance imaging (MRI) was the most commonly used diagnostic technique, and the "halo" and "Y-sign" were strong indicators of CIDH. Three (13%) patients were diagnosed as having CIDH preoperatively, and 87% were confirmed intraoperatively. All patients underwent surgical intervention primarily (73.9%) through an anterior approach. Neurological function improved postoperatively in all patients but one. Dural and arachnoid mater tears were managed by direct suture or covering with a substitute, and only one patient sustained cerebrospinal fluid (CSF) leakage after surgery.
CONCLUSION
IDH mostly involves the lower cervical spine. More than half of the patients had spontaneous CIDH, and some had a relevant cervical trauma history. BSS was the main presentation. It is difficult to diagnose CIDH depending on clinical presentations and radiographic findings. Surgery was an effective treatment for CIDH and can provide a definitive diagnosis. With meticulous management of dural and arachnoid tears, the postoperative incidence of CSF leakage was found to be low.

PURPOSE
The CT Halo sign or Halo sign (HS) refers to ground-glass opacity surrounding a nodule or mass in the lung parenchyma. We conducted a systematic review to find the etiological associations of HS. We also evaluated the diagnostic performances of HS for invasive fungal infections (IFI) in immunosuppressed patients.
METHOD
The systematic review was conducted as per PRISMA guidelines. We searched the PubMed and EMBASE database till June 2018 without any restrictions. Only case reports, case series and original articles published in English language were included. A database created from the electronic searches was compiled and subsequent analysis was done. [PROSPERO registration: CRD42018094739] RESULTS: 168 studies were eligible, which included 51 case reports, 15 prospective studies, 102 retrospective studies. A total of 1977 patients (out of 6371) with HS were identified with age range between <1year-94years. The most common diagnosis in the immunosuppressed, mixed, immunocompetent and not specified groups were IFI (86.9 %, n = 1194), Cryptococcosis (51.6 %, n = 124), Cryptococcosis (40 %, n = 20) and lung neoplasms (81.8 %, n = 36) respectively. 14 studies (11 retrospective, 3 prospective) were included in quantitative analysis. The pooled sensitivity(sn), specificity(sp) and odd's ratio (OR) of HS for diagnosing IFI were 50.4 %, 91 % and 6.61 respectively. Also, HS could not reliably differentiate IPA from mucormycosis in the pooled analysis.
CONCLUSIONS
HS can be seen in a large number of diverse conditions both in immunosuppressed and immunocompetent population. In immunosuppressed patients HS is specific for IFI but cannot rule it out. Additionally, it cannot reliably distinguish between IPA and mucormycosis.

Review
BACKGROUND
Keratoconus remains difficult to diagnose, especially in the early stages. It is a progressive disorder of the cornea that starts at a young age. Diagnosis is based on clinical examination and corneal imaging; though in the early stages, when there are no clinical signs, diagnosis depends on the interpretation of corneal imaging (e.g. topography and tomography) by trained cornea specialists. Using artificial intelligence (AI) to analyse the corneal images and detect cases of keratoconus could help prevent visual acuity loss and even corneal transplantation. However, a missed diagnosis in people seeking refractive surgery could lead to weakening of the cornea and keratoconus-like ectasia. There is a need for a reliable overview of the accuracy of AI for detecting keratoconus and the applicability of this automated method to the clinical setting.
OBJECTIVES
To assess the diagnostic accuracy of artificial intelligence (AI) algorithms for detecting keratoconus in people presenting with refractive errors, especially those whose vision can no longer be fully corrected with glasses, those seeking corneal refractive surgery, and those suspected of having keratoconus. AI could help ophthalmologists, optometrists, and other eye care professionals to make decisions on referral to cornea specialists. Secondary objectives To assess the following potential causes of heterogeneity in diagnostic performance across studies. • Different AI algorithms (e.g. neural networks, decision trees, support vector machines) • Index test methodology (preprocessing techniques, core AI method, and postprocessing techniques) • Sources of input to train algorithms (topography and tomography images from Placido disc system, Scheimpflug system, slit-scanning system, or optical coherence tomography (OCT); number of training and testing cases/images; label/endpoint variable used for training) • Study setting • Study design • Ethnicity, or geographic area as its proxy • Different index test positivity criteria provided by the topography or tomography device • Reference standard, topography or tomography, one or two cornea specialists • Definition of keratoconus • Mean age of participants • Recruitment of participants • Severity of keratoconus (clinically manifest or subclinical) SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register), Ovid MEDLINE, Ovid Embase, OpenGrey, the ISRCTN registry, ClinicalTrials.gov, and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP). There were no date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 29 November 2022.
SELECTION CRITERIA
We included cross-sectional and diagnostic case-control studies that investigated AI for the diagnosis of keratoconus using topography, tomography, or both. We included studies that diagnosed manifest keratoconus, subclinical keratoconus, or both. The reference standard was the interpretation of topography or tomography images by at least two cornea specialists.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted the study data and assessed the quality of studies using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) tool. When an article contained multiple AI algorithms, we selected the algorithm with the highest Youden's index. We assessed the certainty of evidence using the GRADE approach.
MAIN RESULTS
We included 63 studies, published between 1994 and 2022, that developed and investigated the accuracy of AI for the diagnosis of keratoconus. There were three different units of analysis in the studies: eyes, participants, and images. Forty-four studies analysed 23,771 eyes, four studies analysed 3843 participants, and 15 studies analysed 38,832 images. Fifty-four articles evaluated the detection of manifest keratoconus, defined as a cornea that showed any clinical sign of keratoconus. The accuracy of AI seems almost perfect, with a summary sensitivity of 98.6% (95% confidence interval (CI) 97.6% to 99.1%) and a summary specificity of 98.3% (95% CI 97.4% to 98.9%). However, accuracy varied across studies and the certainty of the evidence was low. Twenty-eight articles evaluated the detection of subclinical keratoconus, although the definition of subclinical varied. We grouped subclinical keratoconus, forme fruste, and very asymmetrical eyes together. The tests showed good accuracy, with a summary sensitivity of 90.0% (95% CI 84.5% to 93.8%) and a summary specificity of 95.5% (95% CI 91.9% to 97.5%). However, the certainty of the evidence was very low for sensitivity and low for specificity. In both groups, we graded most studies at high risk of bias, with high applicability concerns, in the domain of patient selection, since most were case-control studies. Moreover, we graded the certainty of evidence as low to very low due to selection bias, inconsistency, and imprecision. We could not explain the heterogeneity between the studies. The sensitivity analyses based on study design, AI algorithm, imaging technique (topography versus tomography), and data source (parameters versus images) showed no differences in the results.
AUTHORS' CONCLUSIONS
AI appears to be a promising triage tool in ophthalmologic practice for diagnosing keratoconus. Test accuracy was very high for manifest keratoconus and slightly lower for subclinical keratoconus, indicating a higher chance of missing a diagnosis in people without clinical signs. This could lead to progression of keratoconus or an erroneous indication for refractive surgery, which would worsen the disease. We are unable to draw clear and reliable conclusions due to the high risk of bias, the unexplained heterogeneity of the results, and high applicability concerns, all of which reduced our confidence in the evidence. Greater standardization in future research would increase the quality of studies and improve comparability between studies.

BACKGROUND
Low health literacy is associated with poor health outcomes in many chronic diseases and may have an important role in determining surgical outcomes. This study aims to comprehensively review the current state of science on adult health literacy in surgery and to identify knowledge gaps for future research.
METHODS
Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic search was conducted to identify all studies from January 2002 through May 2018 that used validated instruments to assess health literacy among adult patients undergoing surgery. Studies were assessed for quality using the Newcastle-Ottawa scale and evaluated on findings by their focus on identifying health literacy levels, understanding associations with surgical outcomes, and/or developing interventions to address low health literacy.
KEY RESULTS
There were 51 studies on health literacy with data from 22,139 patients included in this review. Low health literacy was present in more than one-third of surgical patients (34%, interquartile range 16%-50%). The most commonly used validated instrument for assessment of health literacy in the surgical population was the Newest Vital Sign. Most studies were focused on identifying the prevalence of low health literacy within a surgery population (84%, n = 43). Few studies focused on understanding the association of health literacy to surgical outcomes (12%, n = 6) and even fewer studies developed interventions to address health literacy (4%, n = 2).
DISCUSSION
Low health literacy is common among surgical patients. Important opportunities exist to better understand the role of health literacy in determining surgical outcomes and to develop more health literacy-sensitive models of surgical care. [HLRP: Health Literacy Research and Practice. 2020;4(1):e45-e65.] PLAIN LANGUAGE SUMMARY: Health literacy has not been well-studied in surgery but likely plays an important role. In this article, we reviewed all current research on health literacy in surgery to help us understand where we are at and where we need to go. We found that low health literacy is common and we need more ways to address it in surgery.

INTRODUCTION
The treatment of adult non-traumatic avascular necrosis of the femoral head (AVN; N-ANFH) within an estimated incidence of 5000-7000 cases per annum in Germany remains a challenge. Risk factors include steroids, alcohol abuse, chemotherapy and immunosuppressive medication, but a genetic predisposition has been suggested. Early diagnosis of this often bilateral disease process is essential for successful conservative or joint preserving surgical management. In this review, we present the update German consensus S3 guideline "diagnosis and management for N-ANFH" as a concise summary.
MATERIALS AND METHODS
This systematic review is based on the published literature from January 1, 1970 to April 31, 2013 (German and English language). Inclusion criteria were systematic reviews, meta-analyses and relevant peer review publications. We identified a total of 3715 related publications, of which 422 were suitable according to the SIGN criteria, but only 159 fulfilled our inclusion criteria.
RESULTS AND CONCLUSIONS
Clinical suspicion of N-ANFH mandates radiographic evaluation. If radiographs are normal MRI scans are recommended, which should be evaluated according to the ARCO-classification. Differential diagnoses include transient osteoporosis, bone bruise, insufficiency fracture and destructive arthropathy. Untreated, subchondral fractures commonly occur within 2 years, during which the risk for contralateral involvement is high-thereafter unlikely. Conservative management with Ilomedin and Alendronat can be tried, but other pharmacological or physical treatments are inappropriate. No specific joint preserving procedure can be recommended, but core decompression should be considered in early stages if necrosis is <30 %. In ARCO stages IIIc or IV total hip arthroplasty (THA) should be contemplated, which offers similar outcome compared to osteoarthritis. Young age is the main risk factor for higher revision rates after THA for N-ANFH.

Review
INTRODUCTION
Physical activity (PA) is strongly endorsed for managing chronic conditions, and a vital sign tool (indicator of general physical condition) could alert providers of inadequate PA to prompt counseling or referral. This systematic review examined the use, definitions, psychometric properties, and outcomes of brief PA instruments as vital sign measures, with attention primarily to studies focused on arthritis.
METHODS
Electronic databases were searched for English-language literature from 1985 through 2016 using the terms PA, exercise, vital sign, exercise referral scheme, and exercise counseling. Of the 838 articles identified for title and abstract review, 9 articles qualified for full text review and data extraction.
RESULTS
Five brief PA measures were identified: Exercise Vital Sign (EVS), Physical Activity Vital Sign (PAVS), Speedy Nutrition and Physical Activity Assessment (SNAP), General Practice Physical Activity Questionnaire (GPPAQ), and Stanford Brief Activity Survey (SBAS). Studies focusing on arthritis were not found. Over 1.5 years of using EVS in a large hospital system, improvements occurred in relative weight loss among overweight patients and reduction in glycosylated hemoglobin among diabetic patients. On PAVS, moderate physical activity of 5 or more days per week versus fewer than 5 days per week was associated with a lower body mass index (-2.90 kg/m). Compared with accelerometer-defined physical activity, EVS was weakly correlated (r = 0.27), had low sensitivity (27%-59%), and high specificity (74%-89%); SNAP showed weak agreement (κ = 0.12); GPPAQ had moderate sensitivity (46%) and specificity (50%), and SBAS was weakly correlated (r = 0.10-0.28), had poor to moderate sensitivity (18%-67%), and had moderate specificity (58%-79%).
CONCLUSION
Few studies have examined a brief physical activity tool as a vital sign measure. Initial investigations suggest the promise of these simple and quick assessment tools, and research is needed to test the effects of their use on chronic disease outcomes.

[Interpreter-Aided Psychotherapy for Deaf and Hearing-Impaired Patients - a Systematic Review of Research and Recommendations for Psychotherapists with Normal Hearing and Sign Language Interpreters].
In Germany, deaf patients undergoing psychotherapy have the right to have the costs of a sign language interpreter covered by the insurance since 2001. The effectiveness of interpreter-aided psychotherapy worldwide is disputed. A systematic literature review was conducted on sign language interpreter-aided psychotherapy. Six scientific databases were searched. Two independent raters conducted a 2-step rating process. Out of 1,184 identified publications, 10 studies in German and English language were included. These 10 studies examined between 1 and 85 deaf patients (7-60 years) in different psychotherapeutic settings (8 ambulatory, 4 family therapy). Nine studies reported therapy success. Relevant knowledge (e. g. about culture of deaf people), attitudes (e. g. openness), abilities (e. g. sign language) and general conditions (e. g. declaration for professional secrecy, light conditions) were recommended for psychotherapists with normal hearing and sign language interpreters. Empirical data on psychotherapy with sign language interpreters is low and methodologically limited. The present study can be considered as a starting point for further research.

Deaf people are known to have significantly poorer reading comprehension skills when compared to their hearing counterparts. This poses significant threats to text-based psychological assessments. The plethora of text-based self-report measures available provides ample opportunity to translate/adapt existing tools from text to sign language. This paper systematically reviewed the challenges and facilitators faced in previous translations/adaptations with the view to inform recommendations for future practice. This paper reports the results of a Preferred Reporting Items for Systematic Reviews and Meta-Analyses-informed systematic review of 30 studies that had translated or discussed the translation of a written self-report measure into sign language following screening against inclusion/exclusion criteria. A systematic search (powered by EbscoHost Research Database and using search terms and Boolean operators), was performed in The Allied and Complementary Medicine Database (AMED), Cinahl, Medline, APA PsycInfo, and APA PsycArticles. The Quality Assessment with Diverse Studies tool was used for quality appraisal of the included papers. Challenges/facilitators to effective translation/adaptation were grouped under linguistic, procedural, and cultural. Examples of specific linguistic, procedural, cultural challenges, and facilitators are discussed in the context of previous research and study limitations. Translating/adapting text-based self-report measures to sign language is a linguistically and procedurally demanding endeavor that requires a deep bicultural/bilingual understanding of both deaf and hearing communities. The present results and recommendations can help researchers develop suitably accessible translated/adapted self-report psychological measures and this can have significant implications on healthcare service planning and delivery.
