Meta-Analysis
INTRODUCTION
Novel biomarkers of inflammation and oxidative stress might enhance the early recognition, management, and clinical outcomes of patients with rheumatic diseases (RDs). We assessed the available evidence regarding the pathophysiological role of neopterin, the oxidation product of 7,8-dihydroneopterin, a pteridine generated in macrophages activated by interferon-γ, by conducting a systematic review and meta-analysis of studies reporting its concentrations in biological fluids in RD patients and healthy controls.
METHODS
We searched electronic databases for relevant articles published between inception and 31 August 2023. The risk of bias and the certainty of evidence were assessed using the Joanna Briggs Institute Critical Appraisal Checklist and the Grades of Recommendation, Assessment, Development and Evaluation Working Group system, respectively.
RESULTS
In 37 studies, when compared to healthy controls, RD patients had significantly higher concentrations of neopterin both in plasma or serum (standard mean difference, SMD=1.31, 95% CI 1.01 to 1.61; p<0.001; moderate certainty of evidence) and in the urine (SMD=1.65, 95% CI 0.86 to 2.43, p<0.001; I = 94.2%, p<0.001; low certainty of evidence). The results were stable in sensitivity analysis. There were non-significant associations in meta-regression and subgroup analysis between the effect size and age, male to female ratio, year of publication, sample size, RD duration, C-reactive protein, erythrocyte sedimentation rate, specific type of RD, presence of connective tissue disease, analytical method used, or biological matrix investigated (plasma . serum). By contrast, the effect size was significantly associated with the geographical area in studies assessing serum or plasma and with the type of RD in studies assessing urine.
DISCUSSION
Pending additional studies that also focus on early forms of disease, our systematic review and meta-analysis supports the proposition that neopterin, a biomarker of inflammation and oxidative stress, can be useful for the identification of RDs. (PROSPERO registration number: CRD42023450209).

Review
The presence of a pro-oxidant state in patients with schizophrenia may account for the increased risk of atherosclerosis and cardiovascular disease in this group and supports the potential utility of circulating biomarkers of oxidative stress for risk stratification and management. We investigated this issue by conducting a systematic review and meta-analysis of the association between the circulating concentrations of paraoxonase-1, an antioxidant calcium-dependent high-density lipoprotein (HDL)-associated esterase, with paraoxonase and arylesterase activity in schizophrenia. We searched electronic databases from inception to 31 May 2023 for studies investigating paraoxonase-1 in patients with schizophrenia and healthy controls and assessed the risk of bias and the certainty of evidence (PROSPERO registration number: CRD42023435442). Thirteen studies were identified for analysis. There were no significant between-group differences in paraoxonase (standard mean difference, SMD = 0.12, 95% CI -0.23 to 0.48, = 0.50; extremely low certainty of evidence) or arylesterase activity (SMD = -0.08, 95% CI -0.39 to 0.23, = 0.61; very low certainty of evidence). However, in meta-regression and subgroup analysis we observed significant associations between the SMD of paraoxonase and age ( = 0.003), HDL-cholesterol ( = 0.029), and study country ( = 0.04), and the SMD of arylesterase and age ( = 0.007), body mass index ( = 0.012), HDL-cholesterol ( = 0.002), and pharmacological treatment for schizophrenia ( < 0.001). In the absence of overall between-group differences, our systematic review and meta-analysis suggests that alterations in paraoxonase-1 may reflect a pro-oxidant state in specific subgroups of patients with schizophrenia that require further assessment in appropriately designed studies.

Meta-Analysis
OBJECTIVE
The study aimed to pool and analyze the effects of different forms of exercise on muscle strength (handgrip strength [HGS]), and physical performance (timed up and go test [TUGT], gait speed [GS] and chair stand test [CS]) in older adults with sarcopenia.
METHODS
The effect sizes of all studies retrieved and included by the four databases were analyzed using the network meta-analysis and expressed as standardized mean differences (SMD) and the corresponding 95% confidence intervals (CI).
RESULTS
Twenty studies were included in this study with 1347 older adults with sarcopenia. Compared with control and other intervention groups, resistance training (RT) improved HGS [SMD=3.8, 95% CI (1.3, 6.0), p<0.05] and TUGT [SMD = -1.99, 95% CI (-2.82, -1.16), p<0.05] significantly. comprehensive training (CT) [SMD = -2.04, 95% CI (-3.05, -1.06), Pp<0.05] and Comprehensive training under self-management (CT_SM) [SMD = -2.01, 95% CI (-3.24, -0.78), p<0.05] improved TUGT significantly.
CONCLUSION
In older adults with sarcopenia, RT could improve HGS and TUGT, CT and CT_SM could improve TUGT. There were no significant changes in CS and GS with any of the exercise training modes.

Review
BACKGROUND
Mastocytosis manifests with multisystemic symptoms, often involving the nervous system. Numerous cognitive, neuropsychiatric and neurological alterations have been reported in multiple observational studies.
METHODS
We performed a qualitative systematic literature review of reported data consulting the electronic databases Medline, Scopus, Web of Science, Cochrane, and BASE until June 2023.
RESULTS
We selected 24 studies in which the majority showed that a high proportion of mastocytosis patients suffer cognitive, neuropsychiatric and neurological alterations. The most common disorders and estimated ranges of frequency observed in adults were depression (68%-75%), anxiety, high stress or irritability (27%-54%), cognitive impairment (27%-39%, primarily affecting memory skills), and headaches (55%-69%). Attention challenges and learning difficulties were reported in children at a rate of 13%, while neurodevelopmental disorders occurred at rates of 8%-12%. Frequent white abnormalities in mastocytosis patients with concomitant psychocognitive symptoms have been reported although neuroimaging studies have been performed rarely in this population.
CONCLUSION
Further studies with more comprehensive and homogeneous evaluations and neuroimaging and histological analysis should be performed for a better understanding of these manifestations. An earlier detection and proper management of these symptoms could greatly improve the quality of life of these patients.

Meta-Analysis Review
There is an increasing interest in biomarkers of nitric oxide dysregulation and oxidative stress to guide management and identify new therapeutic targets in patients with chronic obstructive pulmonary disease (COPD). We conducted a systematic review and meta-analysis of the association between circulating metabolites within the arginine (arginine, citrulline, ornithine, asymmetric, ADMA, and symmetric, SDMA dimethylarginine), transsulfuration (methionine, homocysteine, and cysteine) and folic acid (folic acid, vitamin B, and vitamin B) metabolic pathways and COPD. We searched electronic databases from inception to 30 June 2023 and assessed the risk of bias and the certainty of evidence. In 21 eligible studies, compared to healthy controls, patients with stable COPD had significantly lower methionine (standardized mean difference, SMD = -0.50, 95% CI -0.95 to -0.05, = 0.029) and folic acid (SMD = -0.37, 95% CI -0.65 to -0.09, = 0.009), and higher homocysteine (SMD = 0.78, 95% CI 0.48 to 1.07, < 0.001) and cysteine concentrations (SMD = 0.34, 95% CI 0.02 to 0.66, = 0.038). Additionally, COPD was associated with significantly higher ADMA (SMD = 1.27, 95% CI 0.08 to 2.46, = 0.037), SDMA (SMD = 3.94, 95% CI 0.79 to 7.08, = 0.014), and ornithine concentrations (SMD = 0.67, 95% CI 0.13 to 1.22, = 0.015). In subgroup analysis, the SMD of homocysteine was significantly associated with the biological matrix assessed and the forced expiratory volume in the first second to forced vital capacity ratio, but not with age, study location, or analytical method used. Our study suggests that the presence of significant alterations in metabolites within the arginine, transsulfuration, and folic acid pathways can be useful for assessing nitric oxide dysregulation and oxidative stress and identifying novel treatment targets in COPD.

Therapeutic Advances in Urology 2023Carbon dioxide (CO) laser therapy is an emerging treatment for women with stress urinary incontinence (SUI). (Review)
Review
BACKGROUND
Carbon dioxide (CO) laser therapy is an emerging treatment for women with stress urinary incontinence (SUI).
OBJECTIVES
To examine the efficacy of CO laser therapy for management of SUI-related symptoms in women.
DESIGN
A systematic review and meta-analysis of randomized controlled trials and cohort studies.
DATA SOURCES AND METHODS
Four databases were screened until January 2023. All efficacy continuous endpoints were assessed subtraction of the posttreatment from pretreatment values. The data were summarized as mean difference (MD) with 95% confidence interval (CI) using the random-effects model.
RESULTS
A total of 15 studies with 700 patients were analyzed. CO laser therapy significantly decreased the 1-h pad weights at 3 months [ = 5 studies, MD = -3.656 g, 95% CI (-5.198, -2.113), < 0.001], 6 months [ = 6 studies, MD = -6.583 g, 95% CI (-11.158, -2.008), = 0.005], and 12 months [ = 6 studies, MD = -3.726 g, 95% CI (-6.347, -1.106), = 0.005]. Moreover, CO laser therapy significantly decreased the International Consultation of Incontinence Questionnaire-Urinary Incontinence Short Form Scores at 3 months [ = 10 studies, MD = -4.805, 95% CI (-5.985, -3.626), < 0.001] and 12-months [ = 6 studies, MD = -3.726, 95% CI (-6.347, -1.106), = 0.005]. Additionally, CO laser therapy significantly decreased the Pelvic Floor Impact Questionnaire scores at 6 months [ = 2 studies, MD = -11.268, 95% CI (-18.671, -3.865), = 0.002] and 12 months [ = 2 studies, MD = -10.624, 95% CI (-18.145, -3.103), = 0.006]. Besides, CO laser therapy significantly decreased the Urogenital Distress Inventory-6 scores at 3 months [ = 2 studies, MD = -21.997, 95% CI (-32.294, -11.699), < 0.001], but not at 6 months [ = 3 studies, MD = -3.034, 95% CI (-7.357, 1.259), = 0.169]. Lastly, CO laser therapy significantly increased the Vaginal Health Index Score at 6 months [ = 2 studies, MD = 2.826, 95% CI (0.013, 5.638), = 0.047] and 12 months [MD = 1.553, 95% CI (0.173, 2.934), = 0.027].
CONCLUSION
CO laser therapy improved the SUI-related symptoms in women. To obtain solid conclusions, future studies should be well-designed with standardized settings, consistent therapeutic protocols, and long-term follow-up periods.

Review
Burn injuries, as a major public health problem, can lead to high morbidity and mortality. Burns is considered as one of the most devastating injuries globally and the fourth most common injury after traffic accidents, falls and interpersonal violence. Burn injuries can affect human life, such as physical and mental health, functional skills, and performance. Changes in appearance, social isolation, stress, anxiety, depression, low self-esteem, unemployment, financial burden and family problems can occur in these patients. These burn complications can be exacerbated without adequate social support. This systematic review evaluated burn patients' social support and related factors. A systematic search was performed on the international electronic databases such as Scopus, PubMed, Web of Science and Persian electronic databases such as Iranmedex, and Scientific Information Database using keywords extracted from Medical Subject Headings such as 'Burns', 'Social support', 'Perceived social support' and 'Social care' from the earliest to 30 April 2022. The quality of the included studies in this review was assessed using the appraisal tool for cross-sectional studies (AXIS tool). A total of 1677 burn patients were included in this review from 12 studies. Mean score of social support in burn patients based on multidimensional scale of perceived social support, Phillips's social support questionnaire, social support questionnaire, social support scale and Norbeck social support questionnaire were 5.04 (SD = 1.59) of 7, 22.06 (SD = 3.05), 78.20 (SD = 15.00) of 95, 82.24 (SD = 13.70) and 4.14 (SD = 0.99), respectively. Factors such as income, educational attainment, burn surface area, reconstructive surgery, quality of life, self-esteem, socialisation, posttraumatic growth, spirituality, and ego resilience had a significant positive relationship with social support of burns patients. Social support in patients with burn had a significant negative relationship with factors such as psychological distress, having children, life satisfaction, neuroticism and post-traumatic stress disorder. Overall, patients with burns had moderate levels of social support. Therefore, it is recommended that health policymakers and managers make it easier for burn patients to adapt to burns by providing psychological intervention programs and the social support needed by burn patients.

Review
Several studies have shown that an association exists between hyperuricemia and heart failure. Despite several innovative management strategies, heart failure is a significant cause of mortality worldwide. Hyperuricemia in heart failure patients leads to poorer outcomes. Additionally, hyperuricemia can be a strong surrogate marker for increased oxidative stress in heart failure patients. This oxidative stress leads to vascular endothelial damage and is linked to worsening heart failure and subsequent mortality. Hence, the measurement of serum uric acid levels in these patients can predict the present and future risk of complications of heart failure. Despite this knowledge, serum uric acid levels are not usually followed up in heart failure patients. This systematic review aims to give additional clarity to this association. We used research from the last twenty years (2002 to 2022) obtained from databases such as PubMed, PubMed Central (PMC), Google Scholar, and Science Direct. We used the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) 2020 guidelines. We removed duplicates, screened articles on the basis of title and abstract, applied eligibility criteria, and performed quality appraisal. Eventually, 15 articles were selected for review. There were 12 observational studies, two randomized controlled trials, and one meta-analysis. Our review showed that serum uric acid elevation is associated with the severity and complications of congestive heart failure. Serum uric acid can serve as a useful surrogate marker of oxidative stress in congestive heart failure (CHF) patients. The role of xanthine oxidase inhibitors needs to be evaluated further in CHF patients.

Meta-Analysis
BACKGROUND
Metabolic syndrome is affected by many factors, including lifestyle, mood, etc. Self-management of chronic diseases has attracted significant attention from researchers. Some studies have shown that patient self-management is a very important link, which can effectively alleviate the risk of further deterioration of the disease. However, so far, there has been no report on the basis of the summary of self-management intervention programs based on emotion management, which needs further in-depth discussion by researchers.
METHODS
The Medline (PubMed), Embase (Elsevier), PsycINFO (Ovid), CBM, CNKI and Wanfang databases were searched from the establishment of the databases to June 2022, and a total of 25 studies were traced. The inclusion criteria on stress management in patients of metabolic syndrome complicated with psychological symptoms uses meta-analysis. Two investigators independently assessed the risk of bias for each study using the Cochrane risk of bias tool.16 studies and 2687participants and relevant characteristics of studies.
RESULTS
In the effects of intervention measures based on stress management on depression, fasting plasma glucose, 2hFPG, high-density cholesterol, self-management behavior and quality of life in patients with psychological symptoms (depression, anxiety, and schizophrenia) complicated with metabolic diseases, there are statistically significant differences between the intervention group and the control group (P < .05).
CONCLUSIONS
Stress management intervention can effectively improve the health outcomes of patients. In all included analysis indicators, the results of the experimental group are better than those of the control group.

BACKGROUND
The COVID-19 pandemic has brought about far more stressful conditions for people worldwide. As a vulnerable group, older adults have suffered various psychological problems, such as stress, because of this pandemic and have applied various strategies to cope with the dire consequences. This study aimed to synthesize qualitative evidence regarding coping strategies for stressful situations among older adults throughout the COVID-19 pandemic.
METHODS
We searched electronic databases, including Scopus, Embase, PubMed, ProQuest, and the Cochrane Library, based on PRISMA standards. The protocol of this systematic review was registered on the PROSPERO (registration code: CRD42022364831). All relevant English-language articles published between 2019 and November 10, 2022, were searched. We reviewed the reference lists for all the included studies and key references. Two reviewers conducted screening, data extraction, and quality appraisal independently, with disagreements resolved by consensus with all team members. The Joanna Briggs Institute (JBI) checklist was used to assess the quality of studies. A thematic synthesis of the selected studies was conducted.
RESULTS
We included 13 studies in our review. Most studies were conducted in the early months of the COVID-19 pandemic. The stress caused by the COVID-19 pandemic was classified into six categories: health management challenges, stress caused by quarantine, economic challenges, media and bad news stress, virus threats, and challenges related to the use of communication technologies. The strategies used by older adults to cope with these challenges were categorized into five categories: protective strategies, avoidance strategies, maintaining social connections, meaning-based strategies, and fun strategies. This research showed that depending on the situation and conditions, older adults use various strategies to cope with COVID-19.
CONCLUSION
Older adults experience much stress during the COVID-19 pandemic. In most cases, older adults can cope with these challenges with simple strategies from previous experiences and learnings. Older people require educational interventions in some cases, such as those involving communication skills. A better understanding of older adults coping strategies may enable policymakers to develop more effective policies and manage the problems of older adults in post-COVID situations.
