Outcomes Evaluating Quality of Life and Their Measurement Properties in Early-onset Scoliosis: A Systematic Review.

INTRODUCTION: Early-onset scoliosis (EOS) is a spinal deformity affecting children under the age of 10. Understanding the impact of EOS on quality of life can be achieved through appropriate patient/carer-reported outcome measures (PROMs). The aim of this systematic review was to identify, evaluate and summarize the evidence for the measurement properties of health-related quality of life (HR-QoL) outcome measures in the EOS population. METHODS: A 2-stage search methodology was conducted across the PubMed, MEDLINE, EMBASE, EMCARE, PsychINFO, and CINAHL databases. Search 1 identified PROMs used to evaluate the quality of life in EOS, and search 2 identified studies of the measurement properties of these PROMs. Two reviewers performed searching, study screening and selection and assessed studies for risk of bias using the Consensus-based Standards for the selection of health Measurement INstruments (COSMIN) Risk of Bias checklist. One reviewer performed data extraction. Evidence for each measurement property per PROM was summarized and evaluated using a modified GRADE approach. RESULTS: Search 1 identified 19 (10 disease-specific, 9 generic) PROMs that have been used to assess HR-QoL or a relevant domain in the EOS population. Search 2 identified only one PROM (the 24-item Early-Onset Scoliosis Questionnaire, EOSQ) with eligible studies (n=4) evaluating measurement properties. There is low-quality evidence for sufficient content validity, very low-quality evidence for sufficient reliability and low-quality evidence for sufficient criterion validity, specifically regarding the pulmonary function domain) of the EOSQ. Construct validity and responsiveness were rated as indeterminate. There were no studies on measurement error. CONCLUSIONS: Our search strategy found that measurement properties have only been evaluated for one PROM, the EOSQ. There is low-quality evidence for sufficient measurement properties for the EOSQ in patients under the age of 10 with EOS. Further research is needed to improve the quality of evidence for EOSQ measurement properties and investigate other PROMs in this population. LEVEL OF EVIDENCE: Level II.

A report of the number of adolescents screened as warranting further investigation for depression and social anxiety in a pre-operative cohort with idiopathic scoliosis.

INTRODUCTION: Adolescent Idiopathic Scoliosis (AIS) is a common form of scoliosis, causing rotational deformity of the torso in a teenage population. In AIS this happens at a time of particular psychological development and vulnerability and a link between AIS and mental health problems has been observed. MATERIALS AND METHODS: Over a 6 month period, all patients with AIS aged 10-18 referred to a single spinal deformity centre in the UK were screened for symptoms suggestive of a potential diagnosis of depression and social anxiety. RESULTS: Of the 33 patients surveyed, 6 (18%) had scores worthy of further assessment for a potential diagnosis of depression and 19 (59%) worthy of further assessment for a potential diagnosis of social anxiety. DISCUSSION AND CONCLUSION: This small study supports the notion that there is an association between AIS and mental health issues. These initial findings support the practice of routine mental health screening in AIS.

Effectiveness of Nutritional Therapies in Male Factor Infertility Treatment: A Systematic Review and Network Meta-analysis.

BACKGROUND: Nutritional therapies are effective alternative treatments for male infertility or subfertility. These are cost-effective and easily implementable, unlike other advanced invasive treatments. Even moderate improvements in sperm quality could improve spontaneous pregnancy. OBJECTIVE: We aimed to compare the effectiveness of all nutritional therapies in male infertility/subfertility treatment and ranked their efficacy based on type and etiology. We intend to aid clinicians with an evidence-based approach to affordable and safer initial infertility treatment for those who mainly do not wish to have other advanced invasive treatments or could not afford or have access to them. METHODS: We included 69 studies with 94 individual study arms identified from bibliographic databases and registries. We included studies in adult men with proven infertility or subfertility that investigated nutritional or dietary supplement therapies compared with control or placebo and at least reported on a sperm parameter. We undertook a network meta-analysis and performed a pairwise meta-analysis on all sperm parameter outcomes and meta-regression. No language or date restriction was imposed. A systematic article search was concluded on August 29, 2022. RESULTS: Our network meta-analysis is the first to compare all dietary interventions in a single analysis, sub-grouped by intervention type and type of infertility. L-Carnitine with micronutrients, antioxidants, and several traditional herbal supplements showed statistically and clinically significant improvement in sperm quality. Meta-regression identified that improvement in the sperm count, motility and morphology translated into increased pregnancy rates (p < 0.001; p < 0.001; p < 0.002, respectively). In particular, L-carnitine with micronutrient therapy (risk ratio [RR]: 3.60, 95% CI 1.86, 6.98, p = 0.0002), followed by zinc (RR 5.39, 95% CI 1.26, 23.04, p = 0.02), significantly improved pregnancy rates. Men with oligozoospermia (RR 4.89), followed by oligoasthenozoospermia (RR 4.20) and asthenoteratozoospermia (RR 3.53), showed a significant increase in pregnancy rates. CONCLUSION: We ranked nutritional therapies for their ability to improve sperm quality in men with infertility. Nutritional therapies, particularly L-carnitine alone or combined with micronutrients, significantly improved sperm parameters and pregnancy rates even under severe conditions. We believe these affordable solutions may be valuable for people without access to or who do not wish to undergo more invasive and costly fertility treatments.

Evaluating measures of quality of life in adult scoliosis: a systematic review and narrative synthesis.

PURPOSE: To systematically review and synthesise the evidence on the measurement properties of patient-reported outcome measure (PROMs) used to assess the quality of life in patients with adult scoliosis. METHOD: Based on the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and a published protocol, a two-stage search was conducted and reported in line with the Preferred Reporting Items for Systematic review and Meta-analysis (PRISMA). Stage one identified all studies of patients with adult scoliosis which included PROMs of health-related quality of life (HR-QOL). Databases including AMED, CINAHL, EMBASE, Medline, PsychINFO and Pubmed were searched from inception until 31st December 2020. This derived list of PROMs, was then utilised for a stage 2 search to identify studies which evaluated the measurement properties of the PROMs. Two reviewers independently performed the searches, study screening, selection and risk of bias assessment using the COSMIN tool. The overall quality of the evidence was assessed using a modified Grading of Recommendations Assessment, Development and Evaluation approach. RESULTS: Stage one yielded 16 PROMs of HR-QOL with the Oswestry Disability Index (ODI) and Scoliosis Research Society-22 (SRS-22) the most used. Stage two identified three stage one PROMs that fulfilled eligibility criteria: SRS-22, ODI and SRS-22r; with five studies investigating measurement properties in an adult scoliosis population. The SRS-22 was the most comprehensively evaluated PROM in this cohort with very low-quality evidence indicating indeterminate reliability, sufficient construct validity and sufficient responsiveness of the SRS-22. There is very low-quality evidence indicating sufficient responsiveness of the ODI. There is very low-quality evidence indicating indeterminate cross-cultural validity for the SRS-22r. All other measurement properties in the SRS-22, ODI and SRS-22r have not been evaluated. CONCLUSION: A large number of PROMs are being utilised in the adult scoliosis population and of these, the most commonly utilised are the ODI and SRS-22. The SRS-22, ODI and SRS-22r are the only PROMs to have had their measurement properties evaluated in the adult scoliosis population. The findings of this systematic review are that there currently is not sufficient evidence on the measurement properties of any PROMs in adult scoliosis. Further research is now urgently required to assess the measurement properties of these PROMs.

Case series of intradural disc in recurrence of lumbar disc prolapse.

Intradural disc herniation is a rare entity reported at 0.04-1.1% that occurs most commonly in the lumbar spine particularly at L4-L5 region. There is a paucity of literature due to the rarity of this condition. Intradural disc herniations must be considered in the differential diagnosis of prolapsed intervertebral disc disease especially with recent worsening of symptoms and mismatch of unenhanced magnetic resonance induction (MRI) findings. The confirmation is made with intraoperative findings. An intradural disc herniation is most often diagnosed intraoperatively. Contrast enhanced MRI scan is mandatory for pre-operative diagnosis. We report on two cases presenting to our unit in the form of recurrent intradural disc disease following previous lumbar surgery occurring within 3 months of the index procedure in both cases.

Outcomes evaluating quality of life and their measurement properties in early-onset scoliosis: protocol for a systematic review.

INTRODUCTION: Early-onset scoliosis (EOS) is a rare spinal deformity affecting children under the age of 10. Both the condition and its treatment have associated morbidity and can impact quality of life. Understanding this impact can be achieved by using appropriate patient-reported and/or carer-reported outcome measures. The aim of the review described in this protocol is to evaluate the evidence on measurement properties relevant to health-related quality of life outcomes in the EOS population. The focus will be on outcome measures relevant to patients undergoing treatment of EOS under the age of 10. METHODS/ANALYSIS: This protocol is reported in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol and COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) methodology. The MEDLINE, EMBASE, EMCARE, PubMed, PsychINFO and CINAHL databases will be searched using a two-stage search strategy. The first stage will identify measures of HRQoL used in EOS through screening of titles and abstracts. The second stage will assess the measurement properties of those measures identified through screening of full-text articles. The measurement properties of interest are the 'reliability', 'validity' and 'responsiveness' of the instrument. Only English language articles will be considered. Two reviewers will independently review the search results against the eligibility criteria, perform data extraction and assess for risk of bias, with disputes handled by a third reviewer. Data will be quantitatively pooled where possible or reported as a narrative synthesis. The summarised results for each measurement property will be rated against the criteria for good measurement properties following the COSMIN methodology. Two reviewers will assess the body of evidence for each measurement property using modified Grading of Recommendations, Assessment, Development and Evaluation guidelines. ETHICS AND DISSEMINATION: No ethical approval is required for this review and the results will be submitted for publication in peer-reviewed publications. PROSPERO REGISTRATION NUMBER: CRD42020219721.

Evaluating measures of quality of life in adult scoliosis: a protocol for a systematic review and narrative synthesis.

BACKGROUND: Adult scoliosis represents a distinct subgroup of scoliosis patients for whom the diagnosis can have a large impact on their health-related quality of life (HR-QOL). Therefore, HR-QOL patient-reported outcome measures (PROMs) are essential to assess disease progression and the impact of interventions. The objective of this systematic review is to evaluate the measurement properties of HR-QOL PROMs in adult scoliosis patients. METHODS: We will conduct a literature search, from their inception onwards, of multiple electronic databases including AMED, CINAHL, EMBASE, Medline, PsychINFO and PubMed. The searches will be performed in two stages. For both stages of the search, participants will be aged 18 and over with a diagnosis of scoliosis. The primary outcome of interest in the stage one searches will be studies which use PROMs to investigate HR-QOL as defined by the Core Outcome Measures in Effectiveness Trials (COMET) taxonomy, the secondary outcome will be to assess the frequency of use of the various PROMs. In stage two, the primary outcome of interest will be studies which assess the measurement properties of the HR-QOL PROMs identified in stage one. No specific measurement property will be given priority. No planned secondary outcomes have been identified but will be reported if discovered. In stage one, the only restriction on study design will be the exclusion of systematic reviews. In Stage two the only restriction on study design will be the exclusion of full-text articles not available in the English language. Two reviewers will independently screen all citations and abstract data. Potential conflicts will be resolved through discussion. The study methodological quality (or risk of bias) will be appraised using the Consensus-based Standards for the selection of Health Measurement Instruments (COSMIN) checklist. The overall strength of the body of evidence will then be assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. A narrative synthesis will be provided with information presented in the main text and tables to summarise and explain the characteristics and findings of the included studies. The narrative synthesis will explore the evidence for currently used PROMs in adult scoliosis patients and any areas that require further study. DISCUSSION: The review will help clinicians and researchers identify a HR-QOL PROM for use in patients with adult scoliosis. Findings from the review will be published and disseminated through a peer-reviewed journal and conference presentations. SYSTEMATIC REVIEW REGISTRATION: This systematic review has been registered with the International Prospective Register of Systematic Reviews (PROSPERO), reference number: CRD42020219437.
