Meta-Analysis
Multiple sclerosis (MS) is a common autoimmune neurological disease affecting patients' motor, sensory, and visual performance. Stem Cell Transplantation (SCT) is a medical intervention where a patient is infused with healthy stem cells with the purpose of resetting their immune system. SCT shows remyelinating and immunomodulatory functions in MS patients, representing a potential therapeutic option. We conducted this systematic review and meta-analysis that included randomized control trials (RCTs) of SCT in MS patients to investigate its clinical efficacy and safety, excluding observational and non-English studies. After systematically searching PubMed, Web of Science, Scopus, and Cochrane Library until January 7, 2024, nine RCTs, including 422 patients, were eligible. We assessed the risk of bias (ROB) in these RCTs using Cochrane ROB Tool 1. Data were synthesized using Review Manager version 5.4 and OpenMeta Analyst software. We also conducted subgroup and sensitivity analyses. SCT significantly improved patients expanded disability status scale after 2 months (N = 39, MD = - 0.57, 95% CI [- 1.08, - 0.06], p = 0.03). SCT also reduced brain lesion volume (N = 136, MD = - 7.05, 95% CI [- 10.69, - 3.4], p = 0.0002). The effect on EDSS at 6 and 12 months, timed 25-foot walk (T25-FW), and brain lesions number was nonsignificant. Significant adverse events (AEs) included local reactions at MSCs infusion site (N = 25, RR = 2.55, 95% CI [1.08, 6.03], p = 0.034) and hematological disorders in patients received immunosuppression and autologous hematopoietic SCT (AHSCT) (N = 16, RR = 2.33, 95% CI [1.23, 4.39], p = 0.009). SCT can improve the disability of MS patients and reduce their brain lesion volume. The transplantation was generally safe and tolerated, with no mortality or significant serious AEs, except for infusion site reactions after mesenchymal SCT and hematological AEs after AHSCT. However, generalizing our results is limited by the sparse number of RCTs conducted on AHSCT. Our protocol was registered on PROSPERO with a registration number: CRD42022324141.

Review
This review aims to identify and report epidemiological associations between modifiable lifestyle risk factors for overweight or obesity in children and adolescents with type 1 diabetes (T1D). A systematic literature search of medical databases from 1990 to 2023 was undertaken. Inclusion criteria were observational studies reporting on associations between dietary factors, disordered eating, physical activity, sedentary and sleep behaviours and measures of adiposity in children and adolescents (<18 years) with T1D. Thirty-seven studies met inclusion criteria. Studies were mostly cross-sectional (89 %), and 13 studies included adolescents up to 19 years which were included in this analysis. In adolescents with T1D, higher adiposity was positively associated with disordered eating behaviours (DEB) and a higher than recommended total fat and lower carbohydrate intake. A small amount of evidence suggested a positive association with skipping meals, and negative associations with diet quality and sleep stage. There were no published associations between overweight and physical activity, sedentary behaviours and eating disorders. Overall, the findings infer relationships between DEB, fat and carbohydrate intake and adiposity outcomes in people with T1D. Prospective studies are needed to determine causal relationships and to investigate sleep stages. High quality studies objectively measuring physical activity and include body composition outcomes are needed.

Journal of Oral & Maxillofacial Research 2024The purpose of this systematic review is to disclose the impact of autoimmune diseases and their medical treatment on dental implant survival and success. (Review)
Review
OBJECTIVES
The purpose of this systematic review is to disclose the impact of autoimmune diseases and their medical treatment on dental implant survival and success.
MATERIAL AND METHODS
A literature search was conducted using MEDLINE (PubMed), The Cochrane Library and Embase up to December 6, 2021. Any clinical study on patients with an autoimmune disease in whom implant therapy was performed was eligible. The quality of included studies was assessed using the Newcastle-Ottawa Scale. For each autoimmune disease group, data synthesis was divided into three groups: 1) overall results of the autoimmune disease, 2) overall results of corresponding control groups and 3) overall results of the autoimmune disease with a concomitant autoimmune disease (a subgroup of group 1). Descriptive statistics were used.
RESULTS
Of 4,865 identified articles, 67 could be included and mainly comprising case reports and retrospective studies with an overall low quality. Implant survival rate was 50 to 100% on patient and implant level after a weighted mean follow-up of 17.7 to 68.1 months. Implant success was sporadically reported. Data on immunosuppressive medication were too heterogeneously reported to allow detailed analysis.
CONCLUSIONS
Overall, a high implant survival rate was reported in patients with autoimmune diseases. However, the identified studies were characterized by a low quality. No conclusions could be made regarding implant success and the effect of immunosuppressants due to heterogeneous reporting.

Review
OBJECTIVE
Multiple sclerosis is an autoimmune disease of central nervous system (CNS). There are a few articles studying the risk factors of developing MS in men. Male infertility can stem from a range of etiological factors such as genetics or environment. In the context of MS, research suggests a potential link, possibly due to shared immunological and inflammatory mechanisms. Therefore, we designed this study to evaluate the relationship between male infertility and MS development.
MATERIALS AND METHODS
We systematically searched PubMed, Embase, Scopus, web of science, Google scholar and gray literature including references of the references as well as conference papers which were published up to June 2021. The search strategy in PubMed was ("Infertility, Male"[Mesh] OR [Male Infertility] OR [Sterility, Male] OR [Male Sterility] OR [Subfertility, Male] OR [Male Subfertility] OR [Sub-Fertility, Male] OR [Male Sub-Fertility] OR [Sub Fertility, Male]) AND ("Multiple Sclerosis"[Mesh] OR [Sclerosis, Multiple] OR [Sclerosis, disseminated] OR [Disseminated Sclerosis] OR [MS] OR [Multiple Sclerosis, Acute Fulminating]) AND ("Testicular Diseases"[Mesh] OR [Disease, Testicular] OR [Diseases, Testicular] OR [Testicular Disease]) AND ("Multiple Sclerosis"[Mesh] OR [Sclerosis, Multiple] OR [Sclerosis, disseminated] OR [Disseminated Sclerosis] OR [Multiple Sclerosis, Acute Fulminating] OR [MS]).
RESULTS
The literature search revealed 197 articles, after deleting duplicates 109 remained. For the meta-analysis, 3 studies were included. Totally, 2090 MS cases as well as 3895562 healthy subjects were enrolled. One hundred and fourteen infertile men were in MS group and 139716 infertile men were in controls. The pooled OR for male factor infertility and odds of developing MS was1.87 (95% CI: 0.89-3.94) (I=86.1%, P=0.001).
CONCLUSION
The results of this systematic review and meta-analysis show that there is no relationship between male factor infertility and risk of MS.

Meta-Analysis
OBJECTIVE
This meta-analysis includes the systematic literature review and meta-analysis involving clinical trials to assess the efficacy and safety of mesenchymal stem cell (MSC) transplantation for treating T1DM and T2DM.
METHODS
We searched PubMed, ScienceDirect, Web of Science, clinicaltrials.gov, and Cochrane Library for "published" research from their inception until November 2023. Two researchers independently reviewed the studies' inclusion and exclusion criteria. Our meta-analysis included 13 studies on MSC treatment for diabetes.
RESULTS
The MSC-treated group had a significantly lower HbA1c at the last follow-up compared to the baseline (MD: 0.95, 95% CI: 0.33 to 1.57, -value: 0.003< 0.05), their insulin requirement was significantly lower (MD: 0.19, 95% CI: 0.07 to 0.31, -value: 0.002< 0.05), the level of FBG with MSC transplantation significantly dropped compared to baseline (MD: 1.78, 95% CI: -1.02 to 4.58, -value: 0.212), the FPG level of the MSC-treated group was significantly lower (MD: -0.77, 95% CI: -2.36 to 0.81, -value: 0.339 > 0.05), and the fasting C-peptide level of the MSC-treated group was slightly high (MD: -0.02, 95% CI: -0.07 to 0.02, value: 0.231 > 0.05).
CONCLUSION
The transplantation of MSCs has been found to positively impact both types of diabetes mellitus without signs of apparent adverse effects.

Meta-Analysis
BACKGROUND
The concept of treat-to-target (T2T), a treatment strategy in which treatment is directed to reach and maintain a defined goal such as remission or low disease activity (LDA), has been explored for several diseases including rheumatic diseases such as rheumatoid arthritis (RA). However, a comprehensive review of T2T in all rheumatic diseases has not recently been undertaken.
OBJECTIVE
To perform a systematic review and meta-analysis of the efficacy and safety of a T2T strategy in the management of adult patients with inflammatory rheumatic diseases.
METHODS
PUBMED, EMBASE and CINAHL were searched from January 1990 to December 2023 using key words related to a T2T strategy and rheumatic diseases; T2T strategy clinical trials or observational studies were included. Clinical, physical function and radiologic outcomes, cost-effectiveness, and adverse events (AEs) of the T2T strategies were investigated and a random-effect meta-analysis was conducted for the most commonly used outcomes in RA studies.
RESULTS
The search identified 7896 studies, of which 66 fit inclusion criteria, including 50 in RA, 3 in psoriatic arthritis (PsA), 1 in spondyloarthritis (SpA) and 12 in gout. For the studies comparing a T2T strategy with usual care (UC) in RA, 83.3% (20/24) showed a T2T strategy could achieve significantly better clinical outcomes, and the meta-analysis showed that patients treated with a T2T strategy were more likely to be in remission (pooled RR: 1.68 (1.47-1.92), p<0.001] and achieve DAS-28 response (pooled standardised mean difference (SMD): 0.47 (0.26-0.69), P<0.001] at 1 year than patients treated with UC. Sensitivity analyses showed that a T2T strategy with a predefined treatment protocol had better clinical efficacy than that without protocol. In terms of improving physical function and health-related quality of life (HRQoL), 11/19 (57.9%) studies found a T2T strategy was significantly more likely to achieve these than UC, with the meta-analysis for the mean change of HAQ score supporting this conclusion (pooled SMD: 1.48 (0.46-2.51), p=0.004). Five out of 9 studies (55.6%) demonstrated greater benefit regarding radiographic progression from a T2T strategy. In terms of cost-effectiveness and AEs, 2/2 studies found a T2T strategy was more cost-effective than UC and 8/8 studies showed no tendency for AEs to occur more often with a T2T strategy. For the studies in PsA and SpA, a T2T strategy was also demonstrated to be more effective than UC in clinical and functional benefits, but not in radiologic outcomes. All gout studies showed that sUA level could be controlled more effectively with a T2T strategy, and 2 studies revealed that the T2T strategy could inhibit erosion development or crystal deposition.
CONCLUSIONS
For patients with active RA, a T2T strategy has been shown in mulitple studies to increase the likelihood of achieving clinical response and improving HRQoL without increasing economic costs and AEs. Limited studies have shown clinical and functional benefits from T2T strategies in active PsA and SpA. A T2T strategy has also been found to improve clinical and radiologic outcomes in gout. T2T trials in other rheumatic diseases are lacking.

BACKGROUND
This study aims to investigate the incidence and prognosis of malignancy in individuals with thrombospondin type-1 domain-containing 7A (THSD7A)-associated membranous nephropathy (MN).
METHODS
First, we performed a systematic literature review of prevalence of malignancy in THSD7A-associated MN. Then, we conducted a retrospective analysis of 454 patients diagnosed with MN through renal biopsy at our hospital between January 2016 and December 2020. We assessed the presence of serum anti-THSD7A antibodies and performed immunohistochemical staining of renal tissue for THSD7A. Subsequently, we followed patients with THSD7A-associated MN for a minimum of 3-5 years, collecting their clinical, pathological characteristics, and prognosis. Additionally, we conducted a literature review on patients with THSD7A-associated MN in conjunction with malignancy.
RESULTS
We identified a total of nine articles containing comprehensive data on THSD7A-associated MN and malignancy. Among 235 patients with THSD7A-positive MN, 36 individuals had concurrent malignancies, resulting in a malignancy prevalence of 13.3% (95% CI: 8.9-17.7%). In our center, we followed up with 15 patients diagnosed with THSD7A-associated MN and observed three cases of concomitant tumors: two cases of lung adenocarcinoma and one case of small cell lung cancer with multiple metastases. The prevalence of malignancy in our cohort was 20%. Notably, we detected positive THSD7A staining in both renal and lung cancer tissues in one patient with small cell lung cancer.
CONCLUSIONS
Patients with THSD7A-associated MN should undergo vigilant follow-up assessments, with a particular focus on actively seeking potential tumorigenic lesions to prevent misdiagnosis or oversight.

Meta-Analysis
Efficacy of substances containing 3 types of active ingredients-saponins, flavones, and alkaloids in regulation of cytokines in autoimmune diseases a systematic review and Meta-analysis based on animal studies.
OBJECTIVE
To investigate the efficacy of substances containing 3 types of active ingredients-saponins, flavones, and alkaloids on experimental animals with autoimmune diseases (AIDs).
METHODS
The protocol for this systematic review and Meta-analysis was prospectively registered with PROSPERO (CRD42023395741). Searches were conducted in the China National Knowledge Infrastructure, Wanfang, Chinese Science and Technology Journals, China Biomedical, PubMed, Cochrane Library, and Embase databases to screen for animal studies investigating the therapeutic effects of saponins, flavones, or alkaloids on autoimmune diseases; consequently, corresponding data extraction tables were prepared. Systematic Review Centre for Laboratory Animal Experimentation was used to assess the risk of methodological bias in the included literature. RevMan 5.4 was used for the Meta-analysis on the 8 serum cytokines.
RESULTS
A total of 31 studies were included, all of which were randomized controlled studies. Meta-analysis indicated that substances rich in saponins, flavones, and alkaloids reduced serum levels of interleukin (IL)-1β [standardized mean difference () = -1.94, 95% confidence interval () (-2.99, -0.90), 0.0003], IL-6 [ = -1.65, 95% (-2.33, -0.97,) 0.000 01], IL-17 [ = -2.41, 95% (-3.61, -1.20), 0.0001], tumor necrosis factor (TNF)-α [ = -1.84, 95% (-2.61, -1.06), 0.0001], and interferon (IFN)-γ [ = -1.54, 95% (-2.43, -0.65), 0.0007], but increased serum levels of IL-4 [ = 1.30, 95% (0.15, 2.44), 0.03) and IL-10 [ = 2.05, 95% (1.39, 2.70), 0.000 01) in animal models. However, no significant regulatory effect of these three active components was observed on serum levels of IL-2 [ = -0.63, 95% (-1.82, 0.57), 0.30].
CONCLUTIONS
Substances containing saponins, flavones, and alkaloids regulated the changes of immune-related cytokines, it may be a novel dietary substance to relieve and control autoimmune diseases in the future.

Review
OBJECTIVE
This systematic review aimed to evaluate if event-related potentials (ERPs) can be a relevant tool for cognitive dysfunction diagnosis in Multiple Sclerosis (MS).
METHODS
Four databases were consulted (PubMed, Embase, Scielo, and Web of Science). The included studies should include adults with clear MS diagnoses, independently of having cognitive complaints, and all should have been submitted to ERPs (P300, N400 or mismatch negativity (MMN)). The main outcomes evaluated were ERPs' amplitude and/or latency.
RESULTS
425 studies were obtained initially from all databases, with 26 studies fulfilling the eligibility criteria. P300 was the most used ERP (25 studies), showing a reduced amplitude or an increased latency in 84% of those. N400 was evaluated in one study, showing also abnormal results. MMN was addressed in two studies with inconsistent findings. Some studies further suggest that ERPs may show earlier abnormal results compared with neuropsychological tests.
CONCLUSIONS
Most MS patient groups revealed ERP abnormalities, suggesting that these neurophysiological tests may be a relevant and appropriate diagnostic aid method for cognitive impairment in MS.
SIGNIFICANCE
The use of ERPs in MS patients seems able to demonstrate cognitive impairment and its use should be considered as part of the regular patient evaluation.

Review
OBJECTIVES
Primary Sjögren's syndrome (pSS) is a chronic autoimmune disorder characterized by dryness of mucous membranes, predominantly the eyes and mouth, following glandular tissue substitution. The onset of oral dryness constitutes a significant source of discomfort that negatively affects overall quality of life. This systematic review aimed at investigating the differences in Oral Health Impact Profile-14 (OHIP-14) questionnaire scores in patients diagnosed with Sjögren's syndrome compared to sicca syndrome, to assess the influence of the two conditions on oral health. . A systematic electronic and manual search was performed up to December 2023 for studies reporting OHIP-14 questionnaire scores in pSS patients versus sicca syndrome. Two authors independently reviewed, selected, and extracted the data. The outcome was the assessment of OHIP-14 scores in studies comparing pSS- and sicca syndrome-affected patients. Meta-analysis was conducted on available quantitative data.
RESULTS
Literature search retrieved 30 articles, and 3 articles met the criteria for inclusion in the review. Meta-analysis revealed significantly higher scores in patients with sicca syndrome compared to pSS, although salivary flow was markedly reduced in pSS.
CONCLUSIONS
While offering supplementary information to standard tests and supporting the assessment of pSS and sicca syndrome patients, further validation is necessary to establish OHIP-14 validity in determining the impact of pSS and sicca syndrome on patients' quality of life.
