IMPORTANCE
Progressive multifocal leukoencephalopathy can occur in the context of systemic sarcoidosis (S-PML) in the absence of therapeutic immune suppression and can initially be mistaken for neurosarcoidosis or other complications of sarcoidosis. Earlier recognition of S-PML could lead to more effective treatment of the disease.
OBJECTIVE
To describe characteristics of patients with S-PML.
DESIGN, SETTING, AND PARTICIPANTS
For this case series, records from 8 academic medical centers in the United States were reviewed from 2004 to 2022. A systematic review of literature from 1955 to 2022 yielded data for additional patients. Included were patients with S-PML who were not receiving therapeutic immune suppression. The median follow-up time for patients who survived the acute range of illness was 19 months (range, 2-99). Data were analyzed in February 2023.
EXPOSURES
Sarcoidosis without active therapeutic immune suppression.
MAIN OUTCOMES AND MEASURES
Clinical, laboratory, and radiographic features of patients with S-PML.
RESULTS
Twenty-one patients with S-PML not receiving therapeutic immune suppression were included in this study, and data for 37 patients were collected from literature review. The median age of the 21 study patients was 56 years (range, 33-72), 4 patients (19%) were female, and 17 (81%) were male. The median age of the literature review patients was 49 years (range, 21-74); 12 of 34 patients (33%) with reported sex were female, and 22 (67%) were male. Nine of 21 study patients (43%) and 18 of 31 literature review patients (58%) had simultaneous presentation of systemic sarcoidosis and PML. Six of 14 study patients (43%) and 11 of 19 literature review patients (58%) had a CD4+ T-cell count greater than 200/μL. In 2 study patients, a systemic flare of sarcoidosis closely preceded S-PML development. Ten of 17 study patients (59%) and 21 of 35 literature review patients (60%) died during the acute phase of illness. No meaningful predictive differences were found between patients who survived S-PML and those who did not.
CONCLUSIONS AND RELEVANCE
In this case series, patients with sarcoidosis developed PML in the absence of therapeutic immune suppression, and peripheral blood proxies of immune function were often only mildly abnormal. Systemic sarcoidosis flares may rarely herald the onset of S-PML. Clinicians should consider PML in any patient with sarcoidosis and new white matter lesions on brain magnetic resonance imaging.

Meta-Analysis Review
BACKGROUND
Inhaled corticosteroids (ICSs) combined with bronchodilators have been identified to improve outcomes in COPD but also to be associated with certain adverse effects.
OBJECTIVE
We performed a systematic review and meta-analysis to compile and summarize data on the efficacy and safety of dosing levels (high versus medium/low) of ICS alongside ancillary bronchodilators following PRISMA guidelines.
DATA SOURCES
Medline and Embase were systematically searched until December 2021. Randomized, clinical trials (RCTs) that met predefined inclusion criteria were included.
DATA EXTRACTION
Risk ratios (RRs) with 95% confidence intervals (CI) were extracted. Any acute exacerbation of COPD (AECOPD) risk was chosen as the primary efficacy outcome, mortality rate as the primary safety outcome, moderate/severe AECOPD risk as the secondary efficacy outcome and pneumonia risk as the secondary safety outcome. Subgroup analyses of individual ICS agents, of patients with baseline moderate/severe/very severe COPD and of patients with recent COPD exacerbation history were also performed. A random-effects model was used.
RESULTS
We included 13 RCTs in our study. No data on low doses were included in the analysis. High dose ICS was not associated with a statistically significant difference in any AECOPD risk (RR: 0.98, 95% CI: 0.91-1.05, I: 41.3%), mortality rate (RR: 0.99, 95% CI: 0.75-1.32, I: 0.0%), moderate/severe AECOPD risk (RR: 1.01, 95% CI: 0.96-1.06, I: 0.0%) or pneumonia risk (RR: 1.07, 95% CI: 0.86 -1.33, I: 9.3%) compared to medium dose ICS. The same trend was identified with the several subgroup analyses.
CONCLUSION
Our study collected RCTs investigating the optimal dosing level of ICS prescribed alongside ancillary bronchodilators to patients with COPD. We identified that the high ICS dose neither reduces AECOPD risk and mortality rates nor increases pneumonia risk relative to the medium dose.

Dental and Medical Problems 2023Laser protocols for the treatment of dentin hypersensitivity (DH) have not yet been studied systematically. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Laser protocols for the treatment of dentin hypersensitivity (DH) have not yet been studied systematically.
OBJECTIVES
The present study aimed to review clinical trials on the treatment of DH with laser therapy through a systematic review and meta-analysis.
MATERIAL AND METHODS
The search of electronic databases resulted in 562 publications up to April 2020. The inclusion criteria were studies carried out on humans and reporting on the treatment of DH with laser therapy. Case reports, literature reviews and systematic reviews were excluded. Selected by abstract, potentially eligible papers were read in full (n = 160). Independent examiners performed data extraction and the assessment of the risk of bias.
RESULTS
A total of 34 studies were included in the analysis, and 11 in the quantitative analysis. It was observed that most studies followed up patients for a maximum of 6 months (55%). Through the meta-analysis, we observed statistically significant differences between the average pain before and after 3 months of treatment with highand low-power lasers. However, through indirect comparisons, it was observed that the high-power laser showed a greater tendency to reduce the pain levels after 3 months of treatment as compared to the low-power laser, but without a statistically significant difference.
CONCLUSIONS
It was possible to conclude that regardless of the type of laser used in the treatment of DH, this treatment is an effective option for the control of pain symptoms. However, it was not possible to establish a defined treatment protocol, since the evaluation methods are very different from each other. Text for Rewiew and clinical cases.

Frontiers in Pediatrics 2023To evaluate the correlation between tic disorders and allergies and to inform strategies for the treatment and prevention of tic disorders. (Review)
Review
AIM
To evaluate the correlation between tic disorders and allergies and to inform strategies for the treatment and prevention of tic disorders.
METHODS
We conducted online searches of the MEDLINE, Embase, Cochrane, CNKI, CBM, WanFang, and VIP Information databases. Case-control studies and cohort studies related to tic disorders and allergic conditions were searched. Two researchers screened the literature, extracted data, and evaluated quality in strict accordance with the predetermined retrieval strategy and inclusion criteria. Finally, RevMan 5.4 software was used to conduct a meta-analysis. We used the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach to rating the certainty of evidence about each allergy outcome as high, moderate, low, or very low.
RESULTS
We obtained seven eligible studies involving eight allergic conditions. The following allergic conditions were significantly associated with the presence of a tic disorder: asthma (OR = 1.90, 95% CI = 1.57-2.30, < 0.001), allergic rhinitis (OR = 2.61, 95% CI = 1.90-3.57, < 0.001), allergic conjunctivitis (OR = 3.65, 95% CI = 1.53-8,67, = 0.003), eczema (OR = 3.87, 95% CI = 2.24-6.67, < 0.001) and food allergy (OR = 2.79, 95% CI = 1.56-4.99, < 0.001). There was no significant correlation between atopic dermatitis, urticaria, drug allergy, and tic disorder.
CONCLUSION
The occurrence of tic disorders may be associated with the presence of certain allergic disorders. However, whether allergy is one of the causes of tic disorders remains unclear.

Review
Intravenous immunoglobulin (IVIg), which is used to treat multiple neurological conditions, may be associated with serious adverse reactions. The individual neurological disease characteristics associated with adverse reactions, along with strategies to prevent and treat adverse reactions, are uncertain. A systematic review was conducted of the databases PubMed, Embase, and Cochrane Library to summarise studies that report adverse reactions of IVIg therapy in patients with neurological disease. There were 65 studies included in the review. The reported rates of adverse reactions vary widely, but the best evidence suggests rates between 25 and 34% per patient. Common adverse reactions include headache and laboratory abnormalities. Less common but serious adverse reactions included thromboembolic complications and anaphylaxis. Overall, there is a lack of high-quality comparative data to definitively determine if any specific neurological indications are associated with a higher risk of adverse reactions. However, individual neurological disease characteristics possibly associated with an increased likelihood of adverse reactions include limited mobility (as in certain neuromuscular conditions), paraproteinaemia (as in certain peripheral neuropathies), and cardiomyopathy (as in certain myopathies). There is limited evidence to support the effectiveness of prevention and treatment strategies, which may include modification to dose, reduced infusion rate, and premedication. Further studies regarding methods to prevent and treat IVIg-ARs in neurology patients are required.

Vaccine Jun 2023Assessment of COVID-19 vaccines safety during pregnancy is urgently needed. (Meta-Analysis)
Meta-Analysis Review
BACKGROUND
Assessment of COVID-19 vaccines safety during pregnancy is urgently needed.
METHODS
We conducted a systematic review and meta-analysis to evaluate the safety of COVID-19 vaccines, including their components and technological platforms used in other vaccines during pregnancy and animal studies to complement direct evidence. We searched literature databases from its inception to September 2021 without language restriction, COVID-19 vaccine websites, and reference lists of other systematic reviews and the included studies. Pairs of reviewers independently selected, data extracted, and assessed the risk of bias of the studies. Discrepancies were resolved by consensus. (PROSPERO CRD42021234185).
RESULTS
We retrieved 8,837 records from the literature search; 71 studies were included, involving 17,719,495 pregnant persons and 389 pregnant animals. Most studies (94%) were conducted in high-income countries, were cohort studies (51%), and 15% were classified as high risk of bias. We identified nine COVID-19 vaccine studies, seven involving 309,164 pregnant persons, mostly exposed to mRNA vaccines. Among non-COVID-19 vaccines, the most frequent exposures were AS03 and aluminum-based adjuvants. A meta-analysis of studies that adjusted for potential confounders showed no association with adverse outcomes, regardless of the vaccine or the trimester of vaccination. Neither the reported rates of adverse pregnancy outcomes nor reactogenicity exceeded expected background rates, which was the case for ASO3- or aluminum-adjuvanted non-COVID-19 vaccines in the proportion meta-analyses of uncontrolled studies/arms. The only exception was postpartum hemorrhage after COVID-19 vaccination (10.40%; 95% CI: 6.49-15.10%), reported by two studies; however, the comparison with non-exposed pregnant persons, available for one study, found non-statistically significant differences (adjusted OR 1.09; 95% CI 0.56-2.12). Animal studies showed consistent results with studies in pregnant persons.
CONCLUSION
We found no safety concerns for currently administered COVID-19 vaccines during pregnancy. Additional experimental and real-world evidence could enhance vaccination coverage. Robust safety data for non-mRNA-based COVID-19 vaccines are still needed.

Meta-Analysis Review
A systematic literature review and meta-analysis of the incidence of serious or severe hypersensitivity reactions after administration of ferric derisomaltose or ferric carboxymaltose.
BACKGROUND
Intravenous iron is the preferred treatment for patients with iron deficiency anemia in a variety of clinical situations. Although uncommon, administration of modern IV iron formulations can result in hypersensitivity reactions (HSRs) and, rarely, anaphylactic or anaphylactoid reactions.
AIM
The objective of the present study was to systematically review the literature to identify and analyze data on the incidence of HSRs after administration of ferric derisomaltose (FDI) or ferric carboxymaltose (FCM).
METHOD
A prospectively-registered systematic literature review was conducted to identify prospective randomized controlled trials comparing FDI and FCM with other intravenous iron formulations or oral iron. Searches were conducted in PubMed (including MEDLINE), EMBASE, and the Cochrane Library in November 2020. The relative incidence of serious or severe HSRs occurring on the day or day after dosing of intravenous iron, recorded under the standardized Medical Dictionary for Regulatory Activities query for anaphylactic reaction.
RESULTS
Data were obtained from seven randomized controlled trials of FCM (N = 2683) and ten of FDI (N = 3474) enrolling 10,467 patients in total. The number of patients experiencing any serious or severe HSR event was 29/2683 (1.08%) with FCM versus 5/3474 with FDI (0.14%). Bayesian inference of proportions showed the event rates to be significantly lower with FDI relative to FCM.
CONCLUSION
HSR events were uncommon with both intravenous iron formulations; however, the present study showed a significantly lower incidence of HSRs with FDI relative to FCM. Further large-scale, head-to-head trials of the iron formulations would be required to confirm this finding.

BACKGROUND
Suboptimal adherence to inhaled corticosteroid in asthma is a worryingly prevalent yet modifiable factor in uncontrolled disease. Several objective measures of adherence exist, but they are time-consuming. The use of patient-reported adherence measures (PRAMs) could therefore offer a time-efficient pragmatic approach to assessing adherence in clinical practice and potentially the appropriate interventions to improve it.
OBJECTIVES
To identify the PRAMs available for asthma and assess their psychometric quality, accessibility, and usefulness in clinical practice, as well as to provide recommendations for clinicians based on these findings.
METHODS
We conducted a systematic review of six databases. Articles included in this study were English language, full-text, original, asthma-specific PRAMs or development/validation studies of a generic PRAM that had been administered to adults with asthma, investigated inhaled corticosteroid adherence in adults (aged 18 years and older), and assessed at least one COnsensus-based Standards for the selection of health Measurement INstruments measurement property.
RESULTS
We included 15 PRAM developmental and/or validation studies in this systematic review. Studies evaluated a range of COnsensus-based Standards for the selection of health Measurement INstruments measurement properties, but none evaluated all of them.
CONCLUSIONS
Based on this review, we recommend that when a PRAM is used, it should be the Test of the Adherence to Inhalers. However, the Adherence Starts with Knowledge-20 and Adherence Starts with Knowledge-12 may also be useful. Our results highlight the need for PRAM developers to assess questionnaires robustly and provide guidance for clinicians regarding how to act on PRAM answers by developing materials such as decision support tool kits.

Review
INTRODUCTION
Human immunodeficiency virus (HIV) continues to rise in young people among low- and middle-income countries (LMIC). The US National Institutes of Health (NIH) supports the largest public investment in HIV research globally. Despite advancements in the last decade, adolescents and young adults (AYA) remain underrepresented in research to improve HIV prevention and care. We undertook a programme analysis of NIH grants and conducted a targeted review of linked publications on international AYA research across the HIV prevention and care continuum (HPCC) to inform new initiatives to address the needs of AYA in these settings.
METHODS
NIH-funded grants from 2012 to 2017, pertaining to AYA in LMIC, and evaluating areas of HIV prevention, care and/or treatment were identified. A systematic review of publications limited to funded grants was performed in two waves: 2012-2017 and 2018-2021. The review included a landscape assessment and an evaluation of NIH-defined clinical trials, respectively. Data on outcomes across the HPCC were abstracted and analysed.
RESULTS
Among grant applications, 14% were funded and linked to 103 publications for the analytic database, 76 and 27 from the first and second waves, respectively. Fifteen (15%) wave 1 and 27 (26%) wave 2 publications included an NIH-defined clinical trial. Among these, 36 (86%) did not target a key population (men who have sex with men, drug users and sex workers) and 37 (88%) were exclusively focused on sub-Saharan Africa. Thirty (71%) publications addressed at least one HPCC milestone. Specific focus was on milestones in HIV prevention, care or both, for 12 (29%), 13 (31%) and five (12%) of publications, respectively. However, few addressed access to and retention in HIV care (4 [14%]) and none included microbicides or treatment as prevention. More focus is needed in crucial early steps of the HIV care continuum and on biomedical HIV prevention interventions.
DISCUSSION AND CONCLUSIONS
Research gaps remain in this portfolio across the AYA HPCC. To address these, NIH launched an initiative entitled Prevention and Treatment through a Comprehensive Care Continuum for HIV-affected Adolescents in Resource Constrained Settings (PATC H) to generate needed scientific innovation for effective public health interventions for AYA affected by HIV in LMIC.

Meta-Analysis Review
BACKGROUND
Mucormycosis, a rare fungal infection, has shown an increase in the number of reported cases during the COVID-19 pandemic.
OBJECTIVES
To provide a comprehensive insight into the characteristics of COVID-19-associated mucormycosis, through a systematic review and meta-analysis.
METHODS OF DATA SYNTHESIS
Demographic information and clinical features were documented for each patient. Logistic regression analysis was used to predict the risk of mortality.
DATA SOURCES
PubMed, Scopus, Web of Science, Cochrane, CINAHL, Ovid MEDLINE, and FungiSCOPE.
STUDY ELIGIBILITY CRITERIA
Studies reporting individual-level information in patients with adult COVID-19-associated mucormycosis (CAM) between 1 January 2020 and 28 December 2022.
PARTICIPANTS
Adults who developed mucormycosis during or after COVID-19.
INTERVENTIONS
Patients with and without individual clinical variables were compared.
ASSESSMENT OF RISK OF BIAS
Quality assessment was performed based on the National Institutes of Health quality assessment tool for case series studies.
RESULTS
Nine hundred fifty-eight individual cases reported from 45 countries were eligible. 88.1% (844/958) were reported from low- or middle-income countries. Corticosteroid use for COVID-19 (78.5%, 619/789) and diabetes (77.9%, 738/948) were common. Diabetic ketoacidosis (p < 0.001), history of malignancy (p < 0.001), underlying pulmonary (p 0.017), or renal disease (p < 0.001), obesity (p < 0.001), hypertension (p 0.040), age (>65 years) (p 0.001), Aspergillus coinfection (p 0.037), and tocilizumab use during COVID-19 (p 0.018) increased the mortality. CAM occurred on an average of 22 days after COVID-19 and 8 days after hospitalization. Diagnosis of mucormycosis in patients with Aspergillus coinfection and pulmonary mucormycosis was made on average 15.4 days (range, 0-35 days) and 14.0 days (range, 0-53 days) after hospitalization, respectively. Cutaneous mucormycosis accounted for <1% of the cases. The overall mortality rate was 38.9% (303/780).
CONCLUSION
Mortality of CAM was high, and most reports were from low- or middle-income countries. We detected novel risk factors for CAM, such as older age, specific comorbidities, Aspergillus coinfection, and tocilizumab use, in addition to the previously identified factors.
