Meta-Analysis
BACKGROUND
Effective disease surveillance, including that for COVID-19, is compromised without a standardised method for categorising the immunosuppressed as a clinical risk group.
METHODS
We conducted a systematic review and meta-analysis to evaluate whether excess COVID-associated mortality compared to the immunocompetent could meaningfully subdivide the immunosuppressed. Our study adhered to UK Immunisation against infectious disease (Green Book) criteria for defining and categorising immunosuppression. Using OVID (EMBASE, MEDLINE, Transplant Library, and Global Health), PubMed, and Google Scholar, we examined relevant literature between the entirety of 2020 and 2022. We selected for cohort studies that provided mortality data for immunosuppressed subgroups and immunocompetent comparators. Meta-analyses, grey literature and any original works that failed to provide comparator data or reported all-cause or paediatric outcomes were excluded. Odds Ratios (OR) and 95% confidence intervals (CI) of COVID-19 mortality were meta-analysed by immunosuppressed category and subcategory. Subgroup analyses differentiated estimates by effect measure, country income, study setting, level of adjustment, use of matching and publication year. Study screening, extraction and bias assessment were performed blinded and independently by two researchers; conflicts were resolved with the oversight of a third researcher. PROSPERO registration number is CRD42022360755.
FINDINGS
We identified 99 unique studies, incorporating data from 1,542,097 and 56,248,181 unique immunosuppressed and immunocompetent patients with COVID-19 infection, respectively. Compared to immunocompetent people (pooled OR, 95%CI), solid organ transplants (2.12, 1.50-2.99) and malignancy (2.02, 1.69-2.42) patients had a very high risk of COVID-19 mortality. Patients with rheumatological conditions (1.28, 1.13-1.45) and HIV (1.20, 1.05-1.36) had just slightly higher risks than the immunocompetent baseline. Case type, setting income and mortality data matching and adjustment were significant modifiers of excess immunosuppressed mortality for some immunosuppressed subgroups.
INTERPRETATION
Excess COVID-associated mortality among the immunosuppressed compared to the immunocompetent was seen to vary significantly across subgroups. This novel means of subdivision has prospective benefit for targeting patient triage, shielding and vaccination policies during periods of high disease transmission.

Meta-Analysis Review
BACKGROUND
Flow diverters with surface modification (FDSM) are increasingly being used in the treatment of intracranial aneurysms (ANs). We aimed to evaluate the effectiveness and safety across different devices and antiplatelet therapies using a systematic review and meta-analysis.
METHODS
A systematic review was performed to identify original studies of ≥10 patients with intracranial ANs treated with FDSM from database inception through August 2023. Primary effectiveness outcome was the rate of complete AN occlusion at follow-up ≥6 months. Safety outcomes included ischemic stroke, hemorrhage, and in-stent thrombosis, and were stratified by FDSM devices and antiplatelet therapies. Certainty of evidence was evaluated following the Grading of Recommendations, Assessment, Development, and Evaluations approach.
RESULTS
Twenty-seven studies were included, yielding 2161 patients with 2373 ANs. A total of 70.5% of the ANs were located on the internal carotid artery (ICA). Total 10.3% were acutely ruptured. The complete AN occlusion rate was 72.3% at follow-up ≥6 months. Sensitivity analysis in the ICA AN cohort yielded comparable occlusion rates between Pipeline Flex Embolization Device-Shield (80.4%) and Phenox-hydrophilic polymer-coated (77.5%, P = 0.54), but a lower 66.2% rate for Flow Redirection Endoluminal Device-X (P = 0.02). The rate of in-stent thrombosis and stenosis tended to be higher in Phenox-hydrophilic polymer-coated (3.4%) and Flow Redirection Endoluminal Device-X (4.3%) versus Pipeline Flex Embolization Device-Shield (0.8%, P = 0.05).
CONCLUSIONS
FDSM were safe with satisfactory effectiveness for intracranial ANs. More specific investigations are warranted to explore their performance in ANs beyond the ICA and optimal antiplatelet therapy.

British Journal of Sports Medicine Mar 2024To evaluate the effects of sport or physical recreation on participation, mobility and quality of life for adults living with disabilities. (Meta-Analysis)
Meta-Analysis
OBJECTIVES
To evaluate the effects of sport or physical recreation on participation, mobility and quality of life for adults living with disabilities.
DESIGN
Systematic review with meta-analysis.
DATA SOURCES
Six databases searched from inception to May 2022.
ELIGIBILITY CRITERIA
Randomised controlled trials including adults living with a physical or intellectual disability, comparing sport or physical recreation to non-active control.
RESULTS
Seventy-four trials (n=2954; mean age 55 years) were included. Most (70) trials included people with physical disabilities, none evaluated sport and the most common physical recreation activities tested were traditional Chinese exercise (35%), yoga (27%) and dance (18%). Mean frequency and duration was 65 min/session, two times per week for 13 weeks. Most (86%) interventions were led by people with experience and/or training in the recreation activity, and only 37% reported leader experience and/or training working with people with disabilities. Participation was measured as attendance (mean 81%, 30 intervention groups). Physical recreation improved mobility (standardised mean difference (SMD) 0.38, 95% CI 0.07 to 0.69, n=469) and walking endurance (mean difference (MD) 40.3 m, 95% CI 19.5 to 61.1, n=801) with low certainty evidence and balance (Berg Balance Scale, range 0-56 points; MD 3.4 points, 95% CI 2.3 to 4.4, n=906) and quality of life (physical health; SMD 0.37, 95% CI 0.02 to 0.72, n=468) with very low certainty evidence, but not walking speed (MD 0.03 m/s, 95% CI -0.05 to 0.11, n=486).
CONCLUSION
Physical recreation may confer multiple benefits for people living with disabilities regardless of the activity chosen, thus offering a potentially enjoyable and scalable strategy to increase physical activity.

Ophthalmology May 2024To develop guidelines for ocular surveillance and early intervention for individuals with von Hippel-Lindau (VHL) disease.
PURPOSE
To develop guidelines for ocular surveillance and early intervention for individuals with von Hippel-Lindau (VHL) disease.
DESIGN
Systematic review of the literature.
PARTICIPANTS
Expert panel of retina specialists and ocular oncologists.
METHODS
A consortium of experts on clinical management of all-organ aspects of VHL disease was convened. Working groups with expertise in organ-specific features of VHL disease were tasked with development of evidence-based guidelines for each organ system. The ophthalmology subcommittee formulated questions for consideration and performed a systematic literature review. Evidence was graded for topic quality and relevance and the strength of each recommendation, and guideline recommendations were developed.
RESULTS
The quality of evidence was limited, and no controlled clinical trial data were available. Consensus guidelines included: (1) individuals with known or suspected VHL disease should undergo periodic ocular screening (evidence type, III; evidence strength, C; degree of consensus, 2A); (2) patients at risk of VHL disease, including first-degree relatives of patients with known VHL disease, or any patient with single or multifocal retinal hemangioblastomas (RHs), should undergo genetic testing for pathologic VHL disease gene variants as part of an appropriate medical evaluation (III/C/2A); (3) ocular screening should begin within 12 months after birth and continue throughout life (III/C/2A); (4) ocular screening should occur approximately every 6 to 12 months until 30 years of age and then at least yearly thereafter (III/C-D/2A); (5) ocular screening should be performed before a planned pregnancy and every 6 to 12 months during pregnancy (IV/D/2A); (6) ultra-widefield color fundus photography may be helpful in certain circumstances to monitor RHs, and ultra-widefield fluorescein angiography may be helpful in certain circumstances to detect small RHs (IV/D/2A); (7) patients should be managed, whenever possible, by those with subspecialty training, with experience with VHL disease or RHs, or with both and ideally within the context of a multidisciplinary center capable of providing multiorgan surveillance and access to genetic testing (IV/D/2A); (8) extramacular or extrapapillary RHs should be treated promptly (III/C/2A).
CONCLUSIONS
Based on available evidence from observational studies, broad agreement was reached for a strategy of lifelong surveillance and early treatment for ocular VHL disease. These guidelines were endorsed by the VHL Alliance and the International Society of Ocular Oncology and were approved by the American Academy of Ophthalmology Board of Trustees.

BACKGROUND
It is often stated that heart disease is underdiagnosed in COPD. Evidence for this statement comes from primary studies, but these have not been synthesised to provide a robust estimate of the burden of undiagnosed heart disease.
METHODS
A systematic review of studies using active diagnostic techniques to establish the prevalence of undiagnosed major cardiac comorbidities in patients with COPD was carried out. MEDLINE, Embase, Scopus and Web of Science were searched for terms relating to heart failure (specifically, left ventricular systolic dysfunction (LVSD), coronary artery disease (CAD) and atrial fibrillation), relevant diagnostic techniques and COPD. Studies published since 1980, reporting diagnosis rates using recognised diagnostic criteria in representative COPD populations not known to have heart disease were included. Studies were classified by condition diagnosed, diagnostic threshold used and whether participants had stable or exacerbated COPD. Random-effects meta-analysis of prevalence was conducted where appropriate.
RESULTS
In general, prevalence estimates for undiagnosed cardiac comorbidities in COPD had broad confidence intervals, with significant study heterogeneity. Most notably, a prevalence of undiagnosed LVSD of 15.8% (11.1-21.1%) was obtained when defined as left ventricular ejection fraction <50%. Undiagnosed CAD was found in 2.3-18.0% of COPD patients and atrial fibrillation in 1.4% (0.3-3.5%).
CONCLUSION
Further studies using recent diagnostic advances, and investigating therapeutic interventions for patients with COPD and heart disease are needed.

What factors are associated with informal carers' psychological morbidity during end-of-life home care? A systematic review and thematic synthesis of observational quantitative studies.
BACKGROUND
Family carers are central in supporting patients nearing end of life. As a consequence, they often suffer detrimental impacts on their own mental health. Understanding what factors may affect carers' mental health is important in developing strategies to maintain their psychological well-being during caregiving.
AIM
To conduct a systematic review and thematic evidence synthesis of factors related to carers' mental health during end-of-life caregiving.
METHOD
Searches of MEDLINE, CINAHL, PsychINFO, Social Sciences Citation Index, EMBASE, Cochrane Central Register of Controlled Trials and Database of Abstracts of Reviews of Effects 1 January 2009-24 November 2019. We included observational quantitative studies focusing on adult informal/family carers for adult patients at end of life cared for at home considering any factor related to carer mental health (anxiety, depression, distress and quality of life) pre-bereavement. Newcastle-Ottawa Quality Assessment Scale was used. Thematic analysis with box score presentation, and meta-analysis were done where data permitted.
RESULTS
Findings from 63 included studies underpinned seven emergent themes. (31 studies): worse patient psychological symptoms and quality of life were generally associated with worse carer mental health. Patient depression was associated with higher depression in carers (standardised mean difference = 0.59, 95% confidence interval 0.32 to 0.87, = 77%). Patients' other symptoms and functional impairment may relate to carer mental health, but findings were unclear. (14 studies): impact on carers' lives, task difficulty and general burden had clear associations with worse carer mental health. (8 studies): family dynamics and the quality of the carer-patient relationship may be important for carer mental health and are worthy of further investigation. (6 studies): insufficient resources may relate to carers' mental health and warrant further study. (13 studies): self-efficacy and preparedness were related to better mental health. However, findings regarding coping strategies were mixed. (18 studies): informal support given by family and friends may relate to better carer mental health, but evidence on formal support is limited. Having unmet needs was related to worse mental health, while satisfaction with care was related to better mental health. (16 studies): older age was generally associated with better carer mental health and being female was associated with worse mental health.
LIMITATIONS
Studies were mainly cross-sectional (56) rather than longitudinal (7) which raises questions about the likely causal direction of relationships. One-third of studies had samples < 100, so many had limited statistical power to identify existing relationships.
CONCLUSIONS AND FUTURE WORK
Future work must adopt a comprehensive approach to improving carers' mental health because factors relating to carer mental health cover a broad spectrum. The literature on this topic is diverse and difficult to summarise, and the field would benefit from a clearer direction of enquiry guided by explanatory models. Future research should (1) further investigate quality of relationships and finances; (2) better define factors under investigation; (3) establish, through quantitative causal analyses, why factors might relate to mental health; and (4) utilise longitudinal designs more to aid understanding of likely causal direction of associations.

Review
INTRODUCTION
Pyrocarbon promises to be an optimal material choice for radial head arthroplasty (RHA) due to an elastic modulus comparable to the radial diaphysis and thus providing higher biocompatibility. Primary objective was to determine the complications and revision rates related to the usage of these prostheses. The secondary objective was to assess the clinical and radiological outcomes of Pyrocarbon RHAs.
HYPOTHESIS
Pyrocarbon RHAs have good clinical and radiological outcomes with low complications and revisions.
METHODS
Ovid MEDLINE and Embase databases were used to search for studies on outcomes and complications of the RHAs using Pyrocarbon radial head prostheses. The systematic review was designed in accordance with the PRISMA guidelines and included studies were appraised using the MINORS tool. Complications and RHA revision rates were assessed. Functional outcomes were reviewed using PROMs (like MEPI, DASH and BMS), post-op range of motion (using goniometer) and grip strength (using the dynamometer). Postoperative radiological outcomes like peri-prosthetic lucency, radial neck osteolysis, radio-capitellar congruence, capitellar erosion, overstuffing/understuffing and osteoarthritis were reported using radiographs.
RESULTS
A total of 12 studies cumulatively reporting 353 patients who underwent Pyrocarbon RHAs were included in the review. The mean age of patients across the studies ranged from 47 to 54 years of which 50.5% were males. The majority of radial head replacements were done for acute trauma (87.5%) with the remainder done for arthritis (1.7%) and trauma sequelae (10.8%). Mean follow-up period in the selected studies ranged from 18 to 110 months with minimum follow-up across all studies being 12 months. Modular Pyrocarbon (MoPyC, Tornier™) was the implant of choice in ten studies while two studies used the Ascension Pyrocarbon radial head (Ascension Orthopaedics™). Ten studies demonstrated mean MEPI ranging from 75.5 to 96. Mean extension deficit ranged from 6 to 19 degrees, mean flexion from 120 to 140 degrees, mean pronation from 71 to 87 degrees and mean supination from 63 to 85 degrees. Relative grip strength ranged from 69 to 96% of the contralateral limb. Revisions due to implant-related reasons (intra-prosthetic dissociation, prosthetic fracture, peri-prosthetic loosening, radio-capitellar subluxation and understuffed/overstuffed elbow) was 6.8% (24/353). Radial stress shielding and peri-prosthetic lucency was reported in 10 to 100% of patients across different studies but symptomatic implant loosening leading to revision remained rare (2%, 7/353). Radio-capitellar congruence was reported in 81% to 100% cases while capitellar erosion ranged from 0% to 89%. Pyrocarbon implants specific complications included head-neck intra-prosthetic decoupling (1.1%) and pyrocarbon head fractures (0.9%). In total, 5.7% cases underwent re-surgery due to non-RHA related reasons.
DISCUSSION
The pyrocarbon RHA shows good functional outcome, range of motion and low revision rates. This aligns with the working hypothesis of this review. However, pyrocarbon radial head implants have implant-specific complications like pyrocarbon radial head fractures and intra-prosthetic decoupling between stem and head. Despite promising in vitro biomechanical properties, capitellar wear is still a common finding with pyrocarbon RHAs. Despite these factors, pyrocarbon radial head implants are a viable option for radial head arthroplasty.

BACKGROUND
The Jewish Ultra-Orthodox (UO) population is an under-vaccinated minority group that has been disproportionally affected by outbreaks of vaccine-preventable diseases (VPD) such as measles and polio. Underlying reasons remain poorly characterized. We aimed to identify vaccination barriers and enablers in this population.
METHODS
We systematically reviewed the literature (PROSPERO: CRD42021273001), searching Pub-med, Web of science, Medline, PsychNet and Scopus from 1995 to 2021 for quantitative and qualitative primary research in English. Studies published outside the date range, not including barriers or enablers, or that were non-primary research were excluded. We assessed included publications for quality and extracted relevant data based on the 5As taxonomy: access, awareness, affordability, acceptance and activation.
RESULTS
We included nine qualitative and seven quantitative studies from the 125 studies identified. Access barriers included scheduling difficulties, inconvenient opening hours, and logistical difficulties related to having multiple young children. Acceptance barriers included safety concerns. Insufficient knowledge about the importance of vaccine and timely vaccination and the perception of being shielded from infections because of seclusion from wider society were key awareness barriers. Competing priorities, such as work and housework, were the main affordability barriers. Mainstream religious leadership's support for vaccination was an enabler, although recent studies suggest their influence on vaccination behavior is decreasing and influence of anti-vaccination messages is growing.
DISCUSSION
Barriers to vaccination among the UO were mainly logistical, with little religious framing. Safety and efficacy concerns were similar to those reported in the wider community. Decreasing influence of the traditionally pro-vaccine mainstream religious leadership and growing influence of anti-vaccination movements targeting the UO community are new phenomena that require close monitoring. Tailored interventions are required to protect the community and wider society against future VPD outbreaks.

Review
BACKGROUND
Peripheral nerve pathology is frequently encountered in clinical practice among peripheral nerve and extremity surgeons. One major factor limiting nerve regeneration and possibly leading to revision surgeries is the development of traumatic or postoperative adhesions and scarring around nerves. In experimental models, different materials have been studied to limit scar tissue formation when wrapped around nerves.
METHODS
A systematic review of studies describing nerve-wrapping materials in a non-transectional rat sciatic nerve model was performed following the PRISMA guidelines. Literature describing nerve-wrapping methods for the prevention of peripheral nerve scarring in rat sciatic nerve models was identified using PubMed and Web of Science, scanned for relevance and analyzed.
RESULTS
A total of 15 original articles describing 23 different materials or material combinations for nerve wrapping were included. The heterogeneity of the methods used did not allow a meta-analysis, thus, a systematic review was performed. Out of 28 intervention groups, 21 demonstrated a preventive effect on scar tissue formation in at least one qualitative or quantitative assessment method.
CONCLUSIONS
The analyzed literature describes a variety of materials from different origins to limit peripheral nerve scarring and adhesions. Thus, a scar-preventive effect by wrapping peripheral nerves as adhesion prophylaxis seems likely. However, a quantitative comparison of the studies to identify the optimal material or technique is not possible with the diversity of used models and study designs. Therefore, further research needs to be performed to identify the optimal nerve wraps to be used routinely in clinical practice.

JAMA Dermatology Dec 2023Patients with acne are interested in nutraceuticals as a potential treatment option. However, there is uncertainty regarding the efficacy and safety of these products.
IMPORTANCE
Patients with acne are interested in nutraceuticals as a potential treatment option. However, there is uncertainty regarding the efficacy and safety of these products.
OBJECTIVE
To evaluate the evidence for oral nutraceuticals in the treatment of acne.
EVIDENCE REVIEW
The PubMed, Embase, Cochrane Central Register of Controlled Trials, and Web of Science databases were searched from inception through January 30, 2023, to identify randomized clinical trials evaluating oral nutraceutical interventions (ie, vitamins and minerals, botanical extracts, prebiotics, and probiotics) in individuals with acne. Clinician-reported outcomes (eg, investigator global assessment, lesion counts), patient-reported outcomes (eg, quality of life), and adverse events were extracted from the included studies. The quality of evidence was assessed using the Cochrane Risk of Bias checklist tool for randomized clinical trials. Based on the Risk of Bias tool, articles were converted to Agency for Healthcare Research and Quality standards of good, fair, or poor quality.
FINDINGS
A total of 2582 abstracts were identified in the database search, 42 of which met inclusion criteria (a total of 3346 participants). Studies of fair or good quality showed the potential benefit of vitamins B5 and D, botanical extracts (green tea), probiotics, and ω-3 fatty acids in the treatment of acne. These interventions were most frequently associated with decreased lesion counts or improved investigator global assessment scores. Adverse effects were rare for most of the therapies evaluated, but gastrointestinal tract adverse effects were reported for zinc therapy.
CONCLUSIONS AND RELEVANCE
This systematic review suggests a possible role for nutraceutical supplements in the treatment of acne. Physicians should be prepared to discuss the evidence regarding the potential role of nutraceuticals with patients. Many studies were of small size, and future research should focus on larger randomized clinical trials to assess the utility of nutraceuticals in the treatment of acne.
