Meta-Analysis Review
BACKGROUND
EBV is a necessary but not sufficient factor in the pathophysiology of multiple sclerosis (MS). EBV antibodies to the nuclear antigen (EBNA1) and viral capsid antigen (VCA) rise rapidly prior to MS disease manifestations, and their absence has clinical utility with a high negative predictive value. It remains unclear whether EBV levels act as prognostic, monitoring, or pharmacodynamic/response biomarkers. Substantial literature on this topic exists but has not been systematically reviewed. We hypothesized that EBV levels against EBNA1 and VCA are potential prognostic and monitoring biomarkers in MS, and that patient population, MS clinical phenotype, and EBV assay method may play important roles in explaining variation among study outcomes.
METHODS
We systematically searched PubMed and EMBASE from inception to April 1, 2022. After removal of duplicates, records were screened by abstract. Remaining full-text articles were reviewed. Clinical and MRI data were extracted from full-text articles for comparison and synthesis.
RESULTS
Searches yielded 696 unique results; 285 were reviewed in full, and 36 met criteria for data extraction. Heterogeneity in sample population, clinical outcome measures, assay methods and statistical analyses precluded a meta-analysis. EBV levels were not consistently associated with clinical disease markers including conversion from CIS to RRMS, neurological disability, or disease phenotype. Studies using repeated-measures design suggest that EBNA1 levels may temporarily reflect inflammatory disease activity as assessed by gadolinium-enhancing Magnetic Resonance Imaging (MRI) lesions. Limited data also suggest a decrease in EBV levels following initiation of certain disease-modifying therapies.
CONCLUSION
Heterogeneous methodology limited generalization and meta-analysis. EBV antibody levels are unlikely to represent prognostic biomarkers in MS. The areas of highest ongoing promise relate to diagnostic exclusion and pharmacodynamic/disease response. Use of EBV antibodies as biomarkers in clinical practice remains additionally limited by lack of methodological precision, reliability, and validation.

Meta-Analysis
BACKGROUND
It is well known that asymptomatic hyperuricemia and gout play an important role in patients with chronic kidney disease (CKD). However, the effect of uric acid-lowering therapy (ULT) on the prognosis of CKD patients with asymptomatic hyperuricemia remains controversial. Therefore, we aim to investigate the influence of ULT on renal outcomes in these patients.
METHODS
Comprehensive searches were conducted in PubMed, EMBASE, China National Knowledge Internet (CNKI), and the Cochrane Library, up until January 2024. We included randomized controlled trials (RCTs) that evaluated the effects of ULT on renal outcomes in CKD patients with asymptomatic hyperuricemia.
RESULTS
A total of 17 studies were included in the meta-analysis. Compared with placebo or no treatment, ULT preserved the loss of estimated glomerular filtrating rate (eGFR) (Weighted mean difference [WMD] and its 95% confidence intercal(CI): 2.07 [0.15,3.98] mL/min/1.73m) at long-term subgroup. At the same time, short-term subgroup also proved the preserved loss of eGFR (WMD 5.74[2.09, 9.39] mL/min/1.73m). Compared with placebo or no treatment, ULT also reduced the increase in serum creatinine (Scr) at short-term (WMD -44.48[-84.03,-4.92]μmol/L) subgroup and long-term (WMD -46.13[-65.64,-26.62]μmol/L) subgroup. ULT was associated with lower incidence of the events of doubling of Scr without dialysis (relative risk (RR) 0.32 [0.21, 0.49], p < 0.001). However, no difference was found for lower incidence of acute kidney injury (AKI) (p = 0.943).
CONCLUSIONS
According to our study, ULT is beneficial for slowing CKD progression both in short to long-term follow-ups. Additionally, in patients younger than 60 years old, the protective effect of ULT on renal outcome is more pronounced. However, it showed no significant difference in the incidence of AKI. These findings underscore the importance of considering ULT in clinical strategies for CKD patients with asymptomatic hyperuricemia.

Meta-Analysis Review
BACKGROUND
Current soil-transmitted helminth (STH) control guidelines endorse the use of albendazole or mebendazole for school-based targeted preventive chemotherapy (PC), yet their reduced efficacy against Strongyloides stercoralis and Trichuris trichiura presents significant limitations. Emerging evidence indicates that community-wide PC [or mass drug administration (MDA)] using ivermectin, commonly used in other neglected tropical disease (NTD) control programs, may play an important role in controlling these parasites. We conducted a systematic review and meta-analysis to evaluate the effectiveness of ivermectin PC in reducing STH prevalence in endemic populations.
METHODS
We searched Pubmed, EMBASE, and Web of Science on February 14, 2023, for studies that investigated the effectiveness of ivermectin PC, either alone or in combination with other anthelmintic drugs, on STH infections, and provided a measure of STH prevalence before and after PC. We calculated pooled prevalence reductions for each STH using random-effects meta-analyses. Our protocol is available on PROSPERO (registration number CRD42023401219).
RESULTS
A total of 21 were eligible for the systematic review, of which 15 were eligible for meta-analysis. All studies delivered ivermectin through MDA. The pooled prevalence reduction of S. stercoralis following MDA with ivermectin alone was 84.49% (95% CI 54.96-94.66) across five studies and 81.37% (95% CI 61.62-90.96) across seven studies with or without albendazole. The prevalence reduction of T. trichiura was 49.93% (95% CI 18.23-69.34) across five studies with ivermectin alone, and 89.40% (95% CI 73.66-95.73) across three studies with the addition of albendazole. There was high heterogeneity for all syntheses (I > 65%).
CONCLUSIONS
This study underscores the key role of ivermectin-based MDA in addressing limitations in current global STH guidelines in terms of limited efficacy against S. stercoralis and T. trichiura. Based on these findings, revising international STH guidelines to include ivermectin is a promising option to progress the control and eventual elimination of STHs and other NTDs.

Review
Female Enrollment in Rehabilitation Trials: A Systematic Review of Reporting Sex and Female Participation in Randomized Controlled Trials of Poststroke Upper Extremity Rehabilitation Over 50 Years.
OBJECTIVE
To systematically assess the reporting of sex and the percentage of female participants in randomized controlled trials (RCTs) examining interventions for the post-stroke rehabilitation of upper extremity (UE) motor disorders.
DATA SOURCES
CINAHL, Embase, PubMed, Scopus and Web of Science were searched from 1960 to April 1, 2021. Additional articles were identified using the Evidence-Based Review of Stroke Rehabilitation.
STUDY SELECTION
Studies were eligible for inclusion if they (1) were RCTs or crossovers published in English, (2) ≥50% of participants were diagnosed and affected by stroke, (3) included adults ≥18 years old, and (4) applied an intervention to the hemiparetic UE as the primary objective of the study.
DATA EXTRACTION
Two investigators independently screened the title and abstracts, and duplicates were removed. A full-text review was done for studies that met all inclusion criteria. Data were extracted using a custom data extraction template in Covidence and were transferred to online Excel (V16) for data management. Study characteristics and extracted variables were summarized using standard descriptive statistics. Data analyses were performed using SPSS (V29.0).
DATA SYNTHESIS
A total of 1276 RCTs met inclusion criteria, and of these, 5.2% did not report results on sex, accounting for 5.6% of participants. Women have been underrepresented in stroke RCTs, accounting for 38.8% of participants. Female participation was greater in the acute poststroke phase than in the chronic and subacute phases. Over almost 5 decades, there has been a small decrease in the proportion of female participants in these trials.
CONCLUSIONS
Evidence-based medicine for the treatment and prevention of stroke is guided by results from RCTs. Generalizability depends on sufficient representation in clinical trials. Stakeholders, such as funders and journal editors, play a key role in encouraging researchers to enroll enough of both sexes and to report the presence or absence of sex differences in RCTs.

The Spine Journal : Official Journal of... Jun 2024Spinal cord ischemia is a rare but ominous clinical situation with high levels of disability. There are emerging reports on COVID-19 and spinal cord ischemic events.
BACKGROUND CONTEXT
Spinal cord ischemia is a rare but ominous clinical situation with high levels of disability. There are emerging reports on COVID-19 and spinal cord ischemic events.
PURPOSE
To investigate the cardinal manifestations of SARS-CoV-2 associated spinal cord ischemia, review treatment paradigms, and follow outcomes.
STUDY DESIGN
A systematic review.
METHODS
The current study was conducted under Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA) guidelines. The authors searched PubMed, Scopus, Web of Science, and Google Scholar for studies published up to February 12, 2023, on spinal cord ischemia and SARS-CoV-2 infection. Data on patient demographics, study methods, medical records, interventions, and outcomes were extracted from eligible articles. For each data set, the authors performed pooled estimates examining 3 factors of interest, which were (1) predisposing factors (2) treatment regimens, and (3) neurological rehabilitation outcomes. Neurological status was reported as the American Spinal Injury Association (ASIA) impairment scale reported by data sets.
RESULTS
Six data sets were identified. The mean age of the study population was 50 years old, with 66.6% male predominance. Sixty-six percent of the patients had severe COVID-19. Five data sets reported preexisting coagulopathy. ASIA A and B were the most prevalent primary neurological status (80%). The mean interval between COVID-19 and the first neurological deficit was 13 days. Anterior spinal artery lesions were the most prevalent ischemic pattern. The most common treatment regimens were heparin and steroid therapy. Physical rehabilitation showed poor functional outcomes.
CONCLUSIONS
SARS-CoV-2 is associated with spinal cord ischemia through multiple neuropathological mechanisms. Proper coagulation profile control and aggressive rehabilitation may play a promising role in the prevention and recovery of spinal cord infarction in SARS-CoV-2 patients.

Review
Post-dural puncture headache (PDPH) is occasionally an inevitable side effect of neuraxial anesthesia, which can happen after spinal anesthesia or if an accidental dural puncture (ADP) happens during epidural anesthesia. The treatment and prevention options for PDPH differ widely from one institution to another. The management of PDPH is heterogeneous in many institutions because of the absence of clear guidelines and protocols for the management of PDPH. This study aimed to summarize all articles published during the past decade that discussed the treatment or prevention of PDPH. From 2013 to 2023, 345 publications were filtered for all treatment and prevention approaches used for PDPH patients. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) 2020 guidelines were followed for conducting this systematic review, and 38 articles were included for analysis and review. Existing data come from small randomized clinical trials and retrospective or prospective cohort studies. This review supports the effect of oral pregabalin and intravenous aminophylline in both treatment and prevention. Intravenous mannitol, intravenous hydrocortisone, triple prophylactic regimen, and neostigmine plus atropine combination showed effective and beneficial outcomes. On the other hand, neither neuraxial morphine nor epidural dexamethasone showed promising results. Consequently, the use of neuraxial morphine or epidural dexamethasone for the prevention of PDPH remains questionable. Regarding the posture of the patient and its consequences on the incidence of the headache, lateral decubitus is better than a sitting position, and a prone position is better than a supine position. Smaller non-cutting needles play a role in avoiding PDPH. Minimally invasive nerve blocks, including sphenopalatine ganglion or greater occipital nerves, are satisfyingly effective. Epidural blood patches remain the more invasive but the gold standard and ultimate solution in patients resisting medical therapy. This study highlights the need for larger research to define the best approach to prevent and treat PDPH.

Meta-Analysis
BACKGROUND
To indirectly compare the safety of immune checkpoint inhibitors (ICIs) in the treatment of recurrent or metastatic head and neck squamous cell carcinoma (R/M HNSCC) by network meta-analysis (NMA).
METHODS
Through August 1, 2023, we searched PubMed, Cochrane Library, Embase, Web of Science, and ClinicalTrials.gov for randomized clinical trials (RCTs) of ICI-based treatment for R/M HNSCC. Outcomes of interest included overall and organ-specific immune-related adverse events (irAEs). Addis 16.5 software was used to perform NMA. Confidence in Network Meta-Analysis (CINeMA) was used to assess confidence in the evidence.
RESULTS
Nine RCTs were included in this NMA, involving a total of 4016 patients. The general safety of ICI-based treatments in descending order was as follows: Durvalumab + Tremelimumab, Camrelizumab + Chemotherapy, Durvalumab, Toripalimab + Chemotherapy, Pembrolizumab, Pembrolizumab + Chemotherapy, Nivolumab, Tremelimumab. There were differences in the toxicity profile among Toripalimab + Chemotherapy (dermatologic irAEs), Camrelizumab + Chemotherapy (hypothyroidism), Nivolumab + Ipilimumab (hyperthyroidism, pneumonitis), Pembrolizumab (nephrotoxicity), Pembrolizumab + Chemotherapy (colitis). ICI-based treatment increased the incidence of endocrine irAEs (hyperthyroidism and hypothyroidism) and pneumonitis compared to conventional therapy. Besides, the combination of dual ICIs resulted in a greater occurrence of irAEs compared to the use of a single ICI.
CONCLUSIONS
The safety ranking of treatments based on ICIs is significantly influenced by specific irAEs. These irAEs, which vary in type and severity, play a crucial role in determining the overall safety profile of each ICI regimen.

Meta-Analysis
BACKGROUND
Phage therapy could play an important role in the bacterial pneumonia. However, the exact role of phage therapy in bacterial pneumonia is unclear to date.
AIM
The current study aims to find out the role of phage therapy in preclinical models of bacterial pneumonia.
METHODS
The studies were searched in databases with proper MeSH terms along with Boolean operators and selected based on eligibility criteria as per the PRISMA guidelines. The Odd Ratio (OR) was calculated with a 95% confidence interval and the heterogeneity was also calculated. The funnel plot was used to conduct a qualitative examination of publication bias.
RESULTS
The OR was observed to be 0.11 (0.04, 0.27)] after 24 hrs, 0.11 [0.03, 0.34] after 7 days and 0.04 [0.01, 0.15] after 10 days that showed a significant role of phage therapy in reduction of deaths in the bacterial pneumonia models as compared to the placebo group. However, after 48hrs, a non-significant reduction was observed.
CONCLUSION
There was a significant role of phage therapy in the reduction of deaths in the bacterial pneumonia models.

The high prevalence of arterial hypertension and necessity for permanent monitoring of blood pressure requires implementation of new methods of interaction between patient and physician in order to optimize medical care. The purpose of the study was to describe and to evaluate functional possibilities of Russian-speaking mobile applications utilized in collecting blood pressure readings to monitor efficiency of arterial hypertension treatment. The study was carried out in June 2023 in three mobile application stores: Apple Store, Google Play and RuStore. The Russian-speaking applications applied to hypertension self-controlling were considered. For final analysis 45 mobile applications were selected out of 380 applications tested. The most common functions, besides fixing blood pressure levels, were ability of fixing pulse rate (n=41), weight (n=21), sugar level (n=10), blood oxygen saturation (n=8), cholesterol (n=6), rhythm disturbances (n=6) and body temperature (n=5). Additionally, applications made it possible to add tags (n=33), to view statistics (n=41) (including average blood pressure (n=8), pulse pressure (n=9), average daily blood pressure (n=6) and to compare data for different periods of time (n=6), to filter data by tags (n=17), to export statistics (n=32). The 6 applications also supported technology of wireless reception of blood pressure and emergency data. The educational information about blood pressure was enclosed in 17 applications and dietary advice in 12 applications. The content included basic information about blood pressure, treatment, diet, and physical activity. No clinical studies that proved efficiency or inefficiency of analyzed applications were found. None of descriptions comprised both involvement of physicians in development of application and use of clinical recommendations. The results demonstrated large choice of applications used in recording blood pressure with purpose of hypertension self-control. Besides, mobile applications contain various functions and their combinations that can help patient to control blood pressure more effectively. The physicians are to be aware of capabilities of mobile applications developed with purpose of monitoring health of patients.

Review
Antiseizure medications (ASMs) constitute the principal of treatment for patients with epilepsy, where long-term treatment is usually necessary. The purpose of this systematic review is to provide practical and useful information regarding various aspects of the interactions between ASMs and foods and drinks. MEDLINE and ScienceDirect, from the inception to July 15, 2023, were searched for related publications. In both electronic databases, the following search strategy was applied, and the following keywords were used (in title/abstract): "food OR drink" AND "antiepileptic OR antiseizure." The primary search yielded 738 studies. After implementing our inclusion and exclusion criteria, we could identify 19 studies on the issue of interest for our endeavor. Four studies were identified in the recheck process and not by the primary search. All studies provided low level of evidence. Interactions between foods and ASMs are a common phenomenon. Many factors may play a role for such an interaction to come to play; these include drug properties, administration route, and administration schedule, among others. Drugs-foods (-drinks) interactions may change the drug exposure or plasma levels of drugs (e.g., grapefruit juice increases carbamazepine concentrations and the bioavailability of cannabidiol is increased 4-5 folds with concomitant intake of fat-rich food); this may require dosage adjustments. Interactions between ASMs and foods and drinks may be important. This should be taken seriously into consideration when consulting patients and their caregivers about ASMs. Future well-designed investigations should explore the specific interactions between foods (and drinks) and ASMs to clarify whether they are clinically important. PLAIN LANGUAGE SUMMARY: Interactions between antiseizure medications and foods and drinks may be important. This should be taken into consideration in patients with epilepsy.
