OBJECTIVES
Isaac syndrome (IS) is a condition characterized by peripheral nerve hyperexcitability caused by voltage-gated potassium channel (VGKC)-complex antibodies. Muscle twitching, stiffness, hypertrophy, and dysautonomic characteristics, such as hyperhidrosis, are common manifestations. The syndrome can be autoimmune or paraneoplastic, with thymoma being a common cause of paraneoplastic IS. Furthermore, this condition could be handed down from one generation to another. However, there is limited information regarding outcomes, relapses, associated syndromes, associated malignancies (other than thymoma), and treatment options. Despite its rarity, there remains a need for effective management strategies for patients with IS. To address this gap, we conducted a systematic review to summarize the most common and effective treatments of IS in immunomodulatory agents and symptomatic medications, as well as to describe outcomes, relapses, and associated malignancies. Altogether, this review serves to guide clinical practice recommendations for IS and highlight areas for further research.
METHODS
We used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol to conduct a systematic review of cases reposted through the PubMed and Google Scholar databases. The terms "Isaac Syndrome" and "Acquired Neuromyotonia" were used. The Joanna Briggs Institute's critical appraisal tool was used to evaluate the quality of the included studies.
RESULTS
We identified 61 case reports and 4 case series, comprising a total of 70 patients with IS (mean age at onset: 42.5 ± 18 years, and 69% were males). Fourteen cases reported relapses. Thymoma was the most common malignancy associated with IS, followed by lymphoma. Among various serum antibodies, voltage-gated potassium channel-complex antibodies were the most reported antibodies elevated in IS (reported in 38 patients and elevated in 21 patients [55.2%]), followed by acetylcholine ganglionic receptor antibodies, which were reported in 30% of patients (n = 21) and were elevated in 5 cases. The most common electromyography findings were myokymic discharges (n = 22), followed by fasciculations (n = 21) and neuromyotonia (n = 19). For treatment, combining anticonvulsants such as carbamazepine with immunotherapy therapy showed the best results in controlling the symptoms. Among immunotherapy therapies, the combination of plasma exchange plus intravenous high-dose steroids achieved the best results in the acute treatment of IS ([n = 6], with improvement noted in 83.3% [n = 5] of cases). Among the symptomatic treatments with anticonvulsants, carbamazepine was the most efficacious anticonvulsant in treatment of IS, with an average effective dosing of 480 mg/day (carbamazepine was used in 32.3% of acute treatment strategies [n = 23], with improvement noted in 73.9% [n = 17] of cases).
CONCLUSIONS
IS a rare neuromuscular syndrome that tends to affect middle-aged men. These patients should be screened for thymoma and other malignancies such as lymphomas. The management of IS symptoms can be challenging, but based on our review, the combination of multiple immunosuppressives such as IV steroids and plasmapheresis with anticonvulsants such as carbamazepine seems to achieve the best results.

Meta-Analysis
Protective effects of exogenous melatonin therapy against oxidative stress to male reproductive tissue caused by anti-cancer chemical and radiation therapy: a systematic review and meta-analysis of animal studies.
BACKGROUND
Male testicular dysfunction is a considerable complication of anti-cancer therapies, including chemotherapy and radiotherapy, partly due to the increased oxidative stress caused by these treatments. Melatonin is an effective antioxidant agent that protects testicles against physical and toxic chemical stressors in animal models. This study aims to systematically review the melatonin's protective effects against anti-cancer stressors on rodential testicular tissue.
MATERIALS AND METHOD
An extensive search was conducted in Web of Science, Scopus, and PubMed for animal studies investigating exogenous melatonin's protective effects on rodent testicles exposed to anti-cancer chemicals and radiotherapeutic agents. Using the DerSimonian and Laird random-effect model, standardized mean differences and 95% confidence intervals were estimated from the pooled data. The protocol was prospectively registered in the International Prospective Register of Systematic Reviews (PROSPERO: CRD42022355293).
RESULTS
The meta-analysis included 38 studies from 43 studies that were eligible for the review. Rats and mice were exposed to radiotherapy (ionizing radiations such as gamma- and roentgen radiation and radioactive iodine) or chemotherapy (methotrexate, paclitaxel, busulfan, cisplatin, doxorubicin, vinblastine, bleomycin, cyclophosphamide, etoposide, Taxol, procarbazine, docetaxel, and chlorambucil). According to our meta-analysis, all outcomes were significantly improved by melatonin therapy, including sperm quantity and quality (count, motility, viability, normal morphology, number of spermatogonia, Johnsen's testicular biopsy score, seminiferous tubular diameter, and seminiferous epithelial height), serum level of reproductive hormones (Follicle-Stimulating Hormone and testosterone), tissue markers of oxidative stress (testicular tissue malondialdehyde, superoxide dismutase, glutathione peroxidase, catalase, glutathione, caspase-3, and total antioxidant capacity), and weight-related characteristics (absolute body, epididymis, testis, and relative testis to body weights). Most SYRCLE domains exhibited a high risk of bias in the included studies. Also, significant heterogeneity and small-study effects were detected.
CONCLUSION
In male rodents, melatonin therapy was related to improved testicular histopathology, reproductive hormones, testis and body weights, and reduced levels of oxidative markers in testicular tissues of male rodents. Future meticulous studies are recommended to provide a robust scientific backbone for human applications.

Meta-Analysis
BACKGROUND
Recent clinical trials have evaluated the efficacy of vonoprazan-amoxicillin (VA) dual therapy as the first-line treatment for Helicobacter pylori infection in different regions with inconsistent results reported. In this systematic review and meta-analysis, we aimed to evaluate the efficacy of VA dual therapy compared to the currently recommended therapy for eradicating H. pylori.
MATERIALS AND METHODS
A comprehensive search of the PubMed, Cochrane, and Embase databases was performed using the following search terms: ("Helicobacter" OR "H. pylori" OR "Hp") AND ("vonoprazan" OR "potassium-competitive acid blocker" OR "P-CAB") AND ("amoxicillin" OR "penicillin") AND ("dual"). The primary outcome was to evaluate the eradication rate according to intention-to-treat and per-protocol analysis. The secondary outcomes were adverse events and compliance.
RESULTS
A total of 15 studies involving 4, 568 patients were included. The pooled eradication rate of VA dual therapy was 85.0% and 90.0% by intention-to-treat and per-protocol analysis, respectively. The adverse events rate and compliance of VA dual therapy were 17.5% and 96%, respectively. The efficacy of VA dual therapy was superior to proton pump inhibitors-based triple therapy (82.0% vs. 71.4%, p < 0.01) but lower than vonoprazan-containing quadruple therapy (83.1% vs. 93.3%, p = 0.02). 7-day VA dual therapy showed lower eradication rates than 10-day (χ = 24.09, p < 0.01) and 14-day VA dual therapy (χ = 11.87, p < 0.01). The adverse events rate of VA dual therapy was lower than vonoprazan triple therapy (24.6% vs. 30.9%, p = 0.01) and bismuth-containing quadruple therapy (20.5% vs. 47.9%, p < 0.01). No significant difference of compliance was observed between VA dual therapy and each subgroup.
CONCLUSION
VA dual therapy, a novel regimen, showed high efficacy as the first-line treatment for H. pylori eradication, which should be optimized before application in different regions.

Review
OBJECTIVES
To assess the current evidence on the potential of digital health interventions (DHIs) to improve adherence to oral antipsychotics among patients with schizophrenia by assessing the methodologies, feasibility and effectiveness of DHIs as well as the perceptions of relevant stakeholders.
DESIGN
The scoping review was conducted based on the methodologies outlined by Levac and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews guidelines.
DATA SOURCES
PubMed, Embase, Web of Science, Scopus, CINAHL, PsycINFO and the Cochrane Library were searched in August 2023 to identify relevant publications from the previous decade.
ELIGIBILITY CRITERIA
Studies published in English focused on improving medication adherence among adult patients with schizophrenia or schizoaffective disorder via DHIs were selected. Protocols, editorials, comments, perspectives, reviews, correspondence and conference abstracts were excluded.
DATA EXTRACTION AND SYNTHESIS
The extracted data included general information about the study, framework, participants, features and strategies of DHIs, measurement tools for adherence used, and main findings.
RESULTS
In total, 64 studies were included in the qualitative synthesis. Features used in DHIs to improve medication adherence included phone calls, text messages, mobile apps, sensors, web-based platforms and electronic devices. Strategies included medication reminders and monitoring, providing medication-related information and suggestions, other illness management suggestions and individual support. Texting and mobile apps were commonly used as medication reminders and monitoring methods. Additionally, the use of sensors combined with other digital technologies has garnered significant attention. All the interventions were considered acceptable and feasible, and several were assessed in pilot trials. Preliminary findings suggest that DHIs could enhance medication adherence in patients with schizophrenia. However, further validation of their effectiveness is required.
CONCLUSION
DHIs are a promising approach to enhancing medication adherence among patients with schizophrenia. Future interventions should be interactive, focusing on user preference, experience and privacy.

Review
Comparison of the efficacy and safety of hypoglycemic treatments in patients with non-alcoholic fatty liver disease and type-2 diabetes: a systematic review and Bayesian network analysis.
PURPOSE
The association between non-alcoholic fatty liver disease (NAFLD) and metabolic disorders, especially type-2 diabetes (T2DM), has been proven to be bidirectional. Hypoglycemic agents may be promising treatments for those disorders. However, there is currently no approved hypoglycemic therapy for NAFLD. In this review, we aimed to compare the efficacy and safety of twelve different hypoglycemic treatments in patients with NAFLD and T2DM.
METHODS
We systematically screened randomized controlled trials (RCTs) published from March 2013 to March 2023 by searching PubMed, Embase, Medline, and Web of Science without any language restriction. We registered this project on the PROSPERO website: https://www.crd.york.ac.uk/PROSPERO/ (ID: CRD42023429701). All subsequent analyses were performed under the registered protocol. The mean difference (MD) and 95% confidence interval (95% CI) were adapted to evaluate the effect size of the treatment. The surface under the cumulative sorting curve (SUCRA) was used to rank the efficacy of the included treatments.
RESULTS
We included 19 trials involving 1212 patients in total. Insulin plus glucagon-like peptide-1 receptor agonist (GLP1RA) combination therapy was probably the most effective treatment for reducing weight and body mass index (BMI) (SUCRA: 0.93 and 1.00). Thiazolidinediones (TZD) were probably the most effective treatment for reducing glycosylated hemoglobin (HbA1c) and γ-glutamyltranspeptidase (γ-GGT) levels (SUCRA: 0.78 and 0.97). Sodium-glucose cotransporter 2 inhibitors (SGLT2i) had the highest probability of presenting good therapeutic efficacy in reducing triglyceride (TG) levels (SUCRA: 0.72). The most common adverse reactions were gastrointestinal disorders, mainly after the administration of GLP1RA, and mild hypoglycemia, which was closely related to the use of insulin.
CONCLUSION
GLP1RA plus insulin combination therapy, GLP1RA, SGLT2i, and TZD may be the most effective therapeutic methods for patients with NAFLD and T2DM.

Review
BACKGROUND
Atopic dermatitis (AD) is a common skin disease that is hard to completely cure in a short time. Guidelines recommend the use of topical corticosteroids (TCS) as first-line anti-inflammatory therapy for AD, but long-term use has significant side effects. Microecological agents (MA), including probiotics, prebiotics and synbiotics, have been widely reported as a potential adjunctive therapy of AD, but whether MA can contribute to AD treatment is currently controversial. Therefore, we conducted a systematic review and meta-analysis to investigate whether MA as an add-on therapy for AD has synergistic and attenuated effects and to further understand the role of MA in clinical interventions for AD.
METHODS
We systematically searched Medline, Embase, Web of Science, Cochrane Library and PsycINFO databases up to Apr 11, 2023, and bibliographies were also manually searched, for potentially relevant studies regarding MA as additional therapy of AD. The Cochrane Risk of Bias Tool for assessing risk of bias was used to assess the quality of randomized controlled trials (RCTs). Two reviewers screened studies, extracted data, and evaluated the risk of bias independently. The primary outcomes (SCORAD scores and the number of adverse events) and the secondary outcomes (pruritus scores, the quality of life and the frequency of TCS) were extracted from each article. The data were combined and analyzed to quantify the safety and efficacy of the treatment. R (V4.4.3) software was used for data synthesis. The certainty of the evidence was evaluated with the Grade of Recommendation, Assessment, Development and Evaluation (GRADE) system. We also performed a trial sequential analysis to assess the reliability of the evidence.
RESULTS
A total of 21 studies, including 1230 individuals, were identified, 20 of which met the eligibility criteria for the meta-analysis. Our pooled meta-analyses showed that compared with controls, oral MA as an add-on therapy was associated with significantly lower SCORAD scores (MD = -5.30, 95% CI -8.50, -1.55, p < 0.01, I = 81%). However, adverse events, pruritus scores, quality of life, and frequency of TCS use showed no significant difference in this meta-analysis study (p > 0.05).
CONCLUSIONS
This meta-analysis showed that MA plus TCS could be an effective and safe treatment for patients with AD to relieve relevant symptoms, which might be used as an add-on therapy in the treatment of AD. However, due to the limited number of studies, results should be interpreted with caution. Further studies with a larger sample size are needed to explore the optimal protocol of MA plus TCS.

Meta-Analysis
BACKGROUND
Esophageal cancer is a malignant tumor with a low survival rate. Statins, commonly prescribed for their lipid-lowering effects, have been suggested to possess potential chemopreventive properties against various cancers, including esophageal cancer.
OBJECTIVES
This systematic review studied the association between statin intake and esophageal cancer.
METHODS
To conduct this systematic review and meta-analysis, we reviewed studies published between 1980 and June 2023 in Web of Science (WOS), Embase, MEDLINE/PubMed, Scopus, and Cochrane Library databases according to the PRISMA guidelines. Data extraction, quality assessment, and statistical analyses were performed using predefined protocols. We used various statistical tests conducted by Stata statistical software. Statistical significance was considered significant at p < 0.05.
RESULTS
Twenty-one studies were collected and analyzed. The meta-analysis demonstrated that the odds ratio (OR) of esophageal cancer in patients treated with statins was 0.65 (95% CI: 0.57-0.75, p < 0.001) compared to the non-receiving group. The ORs for case-control and cohort studies were 0.67 (95% CI:0.54-0.83, p < 0.001) and 0.62 (95% CI:0.55-0.71, p < 0.001), respectively. The investigation into the relationship between the statins intake and the incidence of esophageal cancer did not reveal any indication of publication bias according to both Begg's test (p = 0.966) and Egger's test (p = 0.113).
CONCLUSION
The results revealed that the odds of esophageal cancer in patients treated with statins decreased by 35% compared to patients not treated with statins. However, further well-designed prospective studies are needed to validate these findings and understand the underlying mechanisms of statins in preventing esophageal cancer.

Meta-Analysis
BACKGROUND
Omalizumab is the only biological agent approved for patients with chronic spontaneous urticaria (CSU), but no biomarker is well established for predicting clinical response to omalizumab.
OBJECTIVE
We aimed to determine the association between baseline total serum IgE levels and the effects of omalizumab in patients with CSU.
METHODS
PubMed, Web of Science, Scopus, and Cochrane Library were systematically searched for relevant studies from inception to August 23, 2022. The research protocol was registered on PROSPERO (CRD42022355592). No language restrictions were applied. A random-effects model was used for meta-analysis.
RESULTS
Ten interventional studies, including 1 randomized controlled trial, were included in the final meta-analysis, and a total of 866 patients with CSU were included. A pooled analysis showed significantly higher serum total IgE levels in complete responders (CRs) than in nonresponders (NRs) (mean difference [MD]: 56.509 IU/mL; 95% confidence interval [CI]: 24.230-88.789) and in partial responders (PRs) than in NRs (MD: 62.688 IU/mL; 95% CI: 32.949-92.427), but no significant difference was detected between CRs and PRs. The mean total IgE levels for CRs, PRs, and NRs were 163.154, 179.926, and 51.535 IU/mL, respectively. Further, the serum total IgE levels in early CRs were significantly higher compared with late CRs (MD: 55.194 IU/mL; 95% CI: 13.402-96.986). The sensitivity analyses with the leave-one-out method validated the robustness of all findings.
CONCLUSIONS
This systematic review and meta-analysis provide convincing evidence that pretreatment total serum IgE levels in patients with CSU are associated with clinical responses to omalizumab.

Meta-Analysis
Our meta-analysis demonstrated that intermittent theta burst stimulation (iTBS)/bilateral-TBS (Bi-TBS) and high-frequency repetitive transcranial magnetic stimulation (HF-rTMS)/bilateral-rTMS (Bi-rTMS) had similar efficacy, acceptability, and safety profiles for antidepressant treatment-resistant major depressive disorder (AD-TRD). In our sensitivity analysis that excluded a study that compared Bi-TBS with Bi-rTMS for older adults, all efficacy outcomes were also comparable between iTBS and HF-rTMS. Because iTBS does not require higher stimulation intensity and a longer stimulus time than conventional HF-rTMS protocols, we speculated that for those with AD-TRD, iTBS/Bi-TBS is a more helpful therapeutic modality in clinical practice than HF-rTMS/Bi-rTMS.

Review
INTRODUCTION
Deep Brain Stimulation (DBS) and Spinal Cord Stimulation (SCS) represent burgeoning treatments for diverse neurological disorders. This systematic review aims to consolidate findings on the immunological and endocrine effects of DBS and SCS, shedding light on the intricate mechanisms of neuromodulation.
MATERIALS AND METHODS
This systematic review, aligned with PRISMA protocols, synthesizes findings from 33 references-20 on DBS and 13 on SCS-to unravel the immunological and endocrine impacts of neuromodulation.
RESULTS
DBS interventions exhibited divergent effects on cytokines, with an increase in hepcidin levels and a variable impact on the IL-6/IL-10 ratio. While some studies reported elevated IL-6, animal studies consistently demonstrated a reduction in IL-1β and IL-6, with no significant changes in TNF-α and an increase in IL-10. Noteworthy hormonal changes included decreased corticosterone and ACTH concentrations and increased oxytocin levels following DBS of the hypothalamus. SCS mirrored similar effects on interleukins, indicating a reduction in IL-6 and IL-1β and an increase in IL-10 levels. Additionally, SCS led to reduced VEGF levels and elevated expression of neurotrophic factors such as BDNF and GDNF, particularly under burst stimulation.
CONCLUSIONS
Both DBS and SCS exert anti-inflammatory effects, manifesting as a decrease in pro-inflammatory cytokines alongside the stimulation of anti-inflammatory cytokine synthesis. These findings, observed in both animal and human models, imply that neurostimulation may modify the trajectory of neurological diseases by modulating local immune responses in an immunomodulatory and endocrine manner. This comprehensive exploration sets the stage for future research endeavors in this evolving domain.
