Types and Effectiveness of Community-Based Cardiovascular Disease Preventive Interventions in Reducing Alcohol Consumption: A Systematic Review and Meta-Analysis.

Cardiovascular disease (CVD) poses a global health challenge, with modifiable risk factors, notably alcohol consumption, impacting its onset and progression. This review synthesizes evidence on the types and effectiveness of community-based interventions (CBIs) aimed at reducing alcohol consumption for CVD prevention. Electronic databases were systematically searched until October 31, 2019, with updates until February 28, 2023. Given the heterogeneity in outcome measures, we narratively synthesized the effectiveness of CBIs, adhering to the synthesis without meta-analysis (SWiM) guidelines for transparent reporting. For selected homogenous studies, a random-effects meta-analysis was utilized to estimate the effects of CBIs on alcohol consumption. Twenty-two eligible studies were included, with 16 demonstrating that CBIs reduced alcohol consumption compared to controls. Meta-analysis findings revealed reductions in above moderate-level alcohol consumption (pooled odds ratio (OR)=0.50, 95% confidence interval (CI): 0.37, 0.68), number of alcohol drinks per week (standardized mean difference=-0.08, 95% CI: -0.14, -0.03), and increased odds of low-risk drinking (pooled OR=1.99, 95% CI: 1.04, 3.81) compared to the control groups. Multi-component interventions (particularly those combining health education, awareness, and promotion activities) and those interventions with a duration of 12 months or more were notably effective. The beneficial effects of CBIs focusing on achieving a reduction in alcohol consumption showed promising outcomes. Implementing such interventions, especially multicomponent interventions, could play a significant role in mitigating the increasing burden of CVDs. Future studies should also consider employing standardized and validated tools to measure alcohol consumption outcomes to enhance the consistency and comparability of findings.

Efficacy and safety of platelet-rich plasma (PRP) in erectile dysfunction (ED): a systematic review and meta-analysis.

Background: Erectile dysfunction (ED) is a prevalent condition in aging men. Meanwhile, platelet-rich plasma (PRP), an emerging treatment alternative, has demonstrated potential in mitigating symptoms associated with ED. Our research aimed to explore the safety and effectiveness of employing PRP as a treatment strategy for ED. Methods: Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocols, our research involved a thorough search across multiple databases: PubMed, Web of Science, Embase, and the Cochrane Controlled Trials Register. To assess the methodological rigor of the studies selected, we applied the modified Jadad scale and the Methodological Index for Non-Randomized Studies (MINORS) scale as evaluation tools. Subsequent to these evaluations, data analysis was conducted. Results: Our analysis included seven non-randomized studies and three randomized controlled trials (RCTs). These studies showed that the International Index of Erectile Function-Erectile Function (IIEF-EF) scores improved significantly after 1, 3, and 6 months of PRP treatment, with increases of 4.05 [95% confidence interval (CI): 2.42, 5.68; P<0.001], 3.73 (95% CI: 2.93, 4.53; P<0.001), and 3.92 (95% CI: 3.00, 4.85; P<0.001) respectively, compared to the baseline scores. Additionally, compared to the placebo group, the PRP group showed significantly higher IIEF-EF scores. PRP treatment also had a beneficial impact on minimal clinically important difference (MCID) and peak systolic velocity (PSV). However, no significant differences were found between the PRP and placebo groups in terms of erectile hardness score (EHS) [mean difference (MD) =0.63; 95% CI: 0.26, 0.99; P<0.001] or visual analog scale (VAS) pain scores (MD =0.24; 95% CI: -0.05, 0.54; P=0.11). Conclusions: Our study results demonstrated significant efficacy and safety of PRP in treating ED. Due to the fact that most of the literature we included was single-arm studies, it was imperative for future research to provide higher-quality evidence for validation.

Global prevalence and predictors of scabies among prisoners: systematic review and meta-analysis.

INTRODUCTION: Scabies is a widespread issue in prisons due to overcrowded living conditions and limited healthcare resources. A recent study published in the Journal of Infection and Public Health discovered that the prevalence of scabies varies greatly among prisoners in different regions and facilities. This review aimed to determine the global prevalence and predictors of scabies among prisoners by conducting a systematic review and meta-analysis. METHODS: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist to report the findings of our systematic review and meta-analysis. Relevant databases including PubMed, Cochrane Library, ScienceDirect, and other grey literature databases were used to search and retrieve articles. The study included both published and unpublished research written in English languages for studies reporting the prevalence of human scabies among prisoners. This review has been registered on PROSPERO. The heterogeneity of the data was evaluated using the I2 statistic. A meta-analysis was conducted using STATA 17 software, with a 95% confidence interval. The researchers also conducted publication bias and sensitivity analysis. RESULTS: The review included 7 studies involving 1, 309,323 prisoners. All included studies involved cross-sectional study design. The prevalence of scabies among prisoners ranges from 0.72% in Italy to 41.01% in Cameroon. The global pooled prevalence of human scabies among prisoners was found to be 6.57% (95% CI; 2.16-19.94). According to subgroup analysis, the overall prevalence of scabies among African prisoners was 19.55% (95% CI; 9.44-40.45), while the prevalence among prisoners outside of Africa was 1.57% (95% CI; 0.77-3.19). The length of time spent in prison, sharing of clothing or beds, and hygiene practices were found to be factors that were significantly associated with the likelihood of prisoners developing human scabies. CONCLUSION: The overall prevalence of human scabies is high among prisoners worldwide. Prisoners who spent more time in prison shared clothing or beds, and had poor hygiene practices were more likely to develop human scabies. Thus, efforts should be made by policymakers and program administrators to decrease the prevalence of scabies in prisons. The protocol for this systematic review and meta-analysis was registered in the International Prospective Register of Systematic Reviews with registration number CRD42024516064.

Effect of Elevated Neutrophil-to-Lymphocyte Ratio on Adverse Outcomes in Patients With Myocardial Infarction: A Systematic Review and Meta-Analysis.

Myocardial infarction (MI), a leading cause of morbidity and mortality globally, is characterized by an underlying inflammatory process driven by atherosclerosis. The neutrophil-to-lymphocyte ratio (NLR), a readily available and cost-effective marker of systemic inflammation, has emerged as a potential predictor of adverse outcomes in patients with MI. This meta-analysis aimed to evaluate the association between elevated NLR and the risk of major adverse cardiovascular events (MACE) and all-cause mortality in patients with MI. A comprehensive literature search was conducted across multiple databases, including Embase, Web of Science, PubMed, and OVID Medicine, to identify relevant studies published from January 1, 2011, onward. Studies reporting the effect of NLR values on MACE and mortality in adult patients with MI, including both ST-elevation (STEMI) and non-ST-elevation (NSTEMI) subtypes, were included. Data extraction and quality assessment were performed independently by multiple authors. The meta-analysis included 37 studies, comprising a total of 18 studies evaluating the risk of MACE and 30 studies assessing all-cause mortality. The pooled analysis revealed a significantly increased risk of MACE (odds ratio [OR] 1.86, 95% confidence interval [CI] 1.53-2.28, P < 0.01) and all-cause mortality (OR 2.29, 95% CI 1.94-2.70, P < 0.01) in patients with elevated NLR compared to those without elevated NLR. Subgroup analyses stratified by follow-up duration and study design further supported the consistent association between elevated NLR and adverse outcomes. In conclusion, this meta-analysis demonstrates a significant association between elevated NLR and an increased risk of MACE and all-cause mortality in patients with MI. These findings highlight the potential clinical utility of NLR as a prognostic marker and underscore the importance of further research to validate its predictive value and establish optimal cutoff values for risk stratification in this patient population.

Prognostic impact of myosteatosis in patients with colorectal cancer undergoing curative surgery: an updated systematic review and meta-analysis.

Background: Colorectal cancer (CRC) is a global health concern, and identifying prognostic factors can improve outcomes. Myosteatosis is fat infiltration into muscles and is a potential predictor of the survival of patients with CRC. Methods: This systematic review and meta-analysis aimed to assess the prognostic role of myosteatosis in CRC. PubMed, Embase, and Cochrane CENTRAL were searched up to 1 August 2023, for relevant studies, using combinations of the keywords CRC, myosteatosis, skeletal muscle fat infiltration, and low skeletal muscle radiodensity. Case-control, prospective, and retrospective cohort studies examining the association between myosteatosis and CRC outcomes after curative intent surgery were eligible for inclusion. Primary outcomes were overall survival (OS), disease-free survival (DFS), and cancer-specific survival (CSS). Results: A total of 10 studies with a total of 9,203 patients were included. The pooled hazard ratio (HR) for OS (myosteatosis vs. no myosteatosis) was 1.52 [95% confidence interval (CI), 1.38-1.67); for CSS, 1.67 (95% CI, 1.40-1.99); and for DFS, 1.89 (95% CI, 1.35-2.65). Conclusion: In patients with CRC undergoing curative intent surgery, myosteatosis is associated with worse OS, CSS, and DFS. These findings underscore the importance of evaluating myosteatosis in patients with CRC to improve outcomes.

Effect of Pulmonary Hypertension on Survival Outcomes in Patients With Transcatheter Aortic Valve Replacement: A Systematic Review and Meta-Analysis.

The aim of this meta-analysis was to determine the effect of pulmonary hypertension (PH) on survival in patients undergoing transcatheter aortic valve replacement (TAVR). The present study was conducted according to the guidelines of Preferred Reporting of Systematic Review and Meta-Analysis (PRISMA). We conducted a comprehensive search of electronic databases including PubMed/MEDLINE, Embase, Cochrane Library, and Web of Science from January 1, 2015, to March 10, 2024. Outcomes assessed in this meta-analysis included early and late all-cause mortality and cardiovascular mortality. Total 15 studies were integrated into the pooled analysis to assess the impact of PH on outcomes among patients undergoing TAVR, comprising a total sample size of 35,732 individuals. The pooled prevalence of PH stood at 52.57% (n=18,767). Predominantly, the studies were conducted in the United States (n=6), followed by Germany (n=3), with one study each from Japan, Italy, Switzerland, Brazil, Poland, and Australia. Pooled analysis showed that risk of short-term mortality was greater in patients with PH compared to patients without PH (risk ratio (RR): 1.46, 95% CI: 1.19 to 1.80). Risk of long-term mortality was greater in patients with PH (RR: 1.42, 95% CI: 1.29 to 1.55). Risk of cardiovascular mortality was also greater in patients with PH compared to patients without PH (RR: 1.66, 95% CI: 1.36 to 2.02). We advocate for further research to address gaps in understanding different types of PH and their impacts on mortality and cardiovascular outcomes.

A Comparison of Rosuvastatin Monotherapy and Rosuvastatin Plus Ezetimibe Combination Therapy in Patients With Type 2 Diabetes: A Meta-Analysis of Randomized Controlled Trials.

Type 2 diabetes mellitus is a metabolic condition where vascular inflammation and oxidative stress contribute to disease progression and associated complications. Although statins are recommended for managing dyslipidemia in diabetes, additional therapies are often required to achieve target lipid levels. This meta-analysis aimed to evaluate the efficacy of rosuvastatin monotherapy versus combination therapy with ezetimibe in patients with type 2 diabetes. A systematic literature search was conducted across multiple databases until April 2024, identifying six randomized controlled trials meeting the inclusion criteria. The meta-analysis revealed that the rosuvastatin plus ezetimibe combination resulted in significantly greater reductions in total cholesterol (mean difference, or MD: 19.49; 95% CI: 13.99 to 24.99), triglycerides (MD: 13.44; 95% CI: 2.04 to 24.85), and low-density lipoprotein cholesterol (MD: -17.68; 95% CI: 12.85 to 22.51) compared to rosuvastatin monotherapy. Conversely, rosuvastatin monotherapy achieved a greater reduction in HbA1c levels (MD: -0.11; 95% CI: -0.17 to -0.04). Subgroup analysis demonstrated that using the same dose of rosuvastatin in both groups led to more significant improvements in lipid parameters with lower heterogeneity. The findings suggest that the rosuvastatin-ezetimibe combination may be a more effective lipid-lowering strategy for patients with type 2 diabetes, though larger studies are needed to assess long-term safety and optimal dosing. Additionally, while rosuvastatin monotherapy provided modest HbA1c reductions, the clinical relevance remains uncertain, and potential risks with high-dose statins should be considered.

Efficacy of Sodium-Glucose Cotransporter 2 Inhibitors in Preventing Heart Failure in Patients Receiving Anthracycline-Based Cancer Therapy: A Systematic Review and Meta-Analysis.

Anthracyclines are effective chemotherapeutic agents widely used to treat various cancers, but their use is limited by the risk of cardiotoxicity and heart failure. While strategies like dose reduction have been explored, there are no well-established therapies to mitigate this risk. Emerging evidence suggests sodium-glucose cotransporter 2 inhibitors (SGLT2i) may have cardioprotective effects, providing a rationale for investigating their potential utility in anthracycline-treated patients. We conducted a systematic review and meta-analysis to synthesize available evidence on the efficacy of SGLT2i in reducing heart failure incidence and mortality in patients undergoing anthracycline-based cancer therapy. Relevant studies were identified through comprehensive database searches and screened based on predefined criteria. Data extraction and quality assessment were performed independently by two reviewers. Four observational studies, encompassing 5,590 patients, were included. The pooled analysis showed a higher but non-significant risk of developing heart failure in the non-SGLT2i group compared to the SGLT2i group (RR = 0.67, 95% CI: 0.40-1.41). The risk of all-cause mortality was significantly lower in patients receiving SGLT2i (RR = 0.55, 95% CI: 0.39-0.77). This meta-analysis suggests SGLT2i are associated with a lower risk of mortality and heart failure incidence in anthracycline-treated patients, although larger studies are needed to confirm these findings. The mechanisms underlying these potential benefits require further elucidation. Despite limitations, this analysis highlights the promising role of SGLT2i as a cardioprotective strategy in this high-risk population.

Prevalence of hepatitis B and C infections among HIV-positive men who have sex with men: A systematic review and meta-analysis.

Background: Human immunodeficiency virus (HIV) infection is highly prevalent and often coexists with other infectious diseases, especially Hepatitis B virus (HBV) and Hepatitis C virus (HCV). Men who have sex with men (MSM) represent a vulnerable population in terms of HIV infection. We aimed to determine the prevalence of HCV, HBV among HIV-infected MSM. Methods: This systematic review and meta-analysis searched PubMed, Cochrane, Scopus, Web of Science, and ProQuest up-to 2023/04/22. All studies reporting the prevalence of HBV or HCV infection in MSM PLHIV were included. Meta-analysis used random effect model for synthesis and I 2 along with prediction interval for heterogeneity. Subgroup analysis based on continent and meta-regression for study size, average age and year of publication were used to explore heterogeneity. Modified Newcastle-Ottawa Scale was used to evaluate the quality of studies according to the protocol (PROSPERO: CRD42023428764). Results: Fifty-six of 5948 studies are included. In 53 studies with 3,07,589 participants, a pooled prevalence of 7% (95% confidence interval [CI]: 5-10) was found for HCV among MSM PLHIV, while a 9% (95% CI: 4-18) prevalence was found for HBV infection from five studies which included 5641 MSM PLHIV. Asia reported the lowest pooled prevalence at 5.84% (95% CI: 2.98-11.13) for HCV while Europe reported the highest pooled prevalence at 7.76% (95% CI: 4.35-13.45). Baujat plot and influence diagnostic identified contributors to influence and between-study heterogeneity. Sensitivity analyses omitting these studies result in considerably more precise estimates. Another sensitivity analysis as leave-one-out meta-analysis did not change any pooled estimate significantly. Conclusion: There is a significant burden of HCV and HBV among MSM PLHIV worldwide, with varying prevalence rates. Future studies should focus on these multimorbidity clusters and investigate factors influencing disease burden, long-term outcomes, optimal testing strategies, and tailored interventions.

Prevalence of preoperative depression and adverse outcomes in older patients undergoing elective surgery: A systematic review and meta-analysis.

STUDY OBJECTIVE: Depression is a common cause of long-lasting disability and preoperative mental health state that has important implications for optimizing recovery in the perioperative period. In older elective surgical patients, the prevalence of preoperative depression and associated adverse pre- and postoperative outcomes are unknown. This systematic review and meta-analysis aimed to determine the prevalence of preoperative depression and the associated adverse outcomes in the older surgical population. DESIGN: Systematic review and meta-analysis. SETTING: MEDLINE, MEDLINE Epub Ahead of Print and In-Process, In-Data-Review & Other Non-Indexed Citations, Embase/Embase Classic, Cochrane CENTRAL, and Cochrane Database of Systematic Reviews, ClinicalTrials.Gov, the WHO ICTRP (International Clinical Trials Registry Platform) for relevant articles from 2000 to present. PATIENTS: Patients aged ≥65 years old undergoing non-cardiac elective surgery with preoperative depression assessed by tools validated in older adults. These validated tools include the Geriatric Depression Scale (GDS), Hospital Depression and Anxiety Scale (HADS), Beck Depression Inventory-II (BDI), Patient Health Questionnaire-9 (PHQ-9), and the Centre for Epidemiological Studies Depression Scale (CESD). INTERVENTIONS: Preoperative assessment. MEASUREMENT: The primary outcome was the prevalence of preoperative depression. Additional outcomes included preoperative cognitive impairment, and postoperative outcomes such as delirium, functional decline, discharge disposition, readmission, length of stay, and postoperative complications. MAIN RESULTS: Thirteen studies (n = 2824) were included. Preoperative depression was most assessed using the Geriatric Depression Scale-15 (GDS-15) (n = 12). The overall prevalence of preoperative depression was 23% (95% CI: 15%, 30%). Within non-cancer non-cardiac mixed surgery, the pooled prevalence was 19% (95% CI: 11%, 27%). The prevalence in orthopedic surgery was 17% (95% CI: 9%, 24%). In spine surgery, the prevalence was higher at 46% (95% CI: 28%, 64%). Meta-analysis showed that preoperative depression was associated with a two-fold increased risk of postoperative delirium than those without depression (32% vs 23%, OR: 2.25; 95% CI: 1.67, 3.03; I2: 0%; P ≤0.00001). CONCLUSIONS: The overall prevalence of older surgical patients who suffered from depression was 23%. Preoperative depression was associated with a two-fold higher risk of postoperative delirium. Further work is needed to determine the need for depression screening and treatment preoperatively.

The Impact of Interleukin-17 Inhibitors on Major Adverse Cardiovascular Events in Psoriasis or Psoriatic Arthritis Patients Naive to Biologic Agents: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

The objective of this systematic review is to determine the effects of IL-17 inhibitors on major adverse cardiovascular events (MACEs) in patients with either psoriasis (PsO) or psoriatic arthritis (PsA). A systematic literature search in three databases (Medline, Embase, and the Cochrane Library for Randomized Controlled Trials) was conducted on December 7, 2022 for randomized controlled trials of patients with PsO/PsA treated with IL-17 inhibitors that reported confirmed MACEs. Two reviewers screened titles and abstracts and identified papers for full-text review. Exclusion criteria included trials that included the previous use of biological disease-modifying anti-rheumatic drugs. The Mantel-Haenszel random-effect method was utilized to calculate risk ratios and heterogeneity was measured by χ2 test and I2 statistics. Funnel plot analysis was undertaken to detect potential publication bias. Of the 919 references identified, nine RCT studies were included in the meta-analysis (n=2,096 patients). There was no statistically significant correlation between the use of IL-17 inhibitors and change in risk of MACEs (Risk Ratio 0.56; 95% CI 0.15 to 2.14; p = 0.40). Subgroup analysis of secukinumab or ixekizumab also did not demonstrate these changes. Additionally, there was no detectable dose-dependent effect of IL-17 inhibitors. In conclusion, IL-17 inhibitor use is not correlated with a change in MACE risk in patients with PsO/PsA who previously did not receive biologic disease-modifying anti-rheumatic drugs.

Laparoscopic versus open surgery in treating patients with gallbladder cancer: a systematic review and meta-analysis.

Background: Concerns over the security of laparoscopic radical operation for gallbladder cancer (GBC) persist. This systematic review and meta-analysis attempted to compare the safety and efficacy of laparoscopic surgery (LS) versus open surgery (OS) in the treatment of GBC. Methods: The PubMed, EMBASE, and Web of Science were searched from inception to July 18, 2022. Literature search, quality assessment, and data extraction were completed independently and in duplicate. Effect-size estimates expressed as weighted mean difference (WMD) or odds ratio (OR) with 95% confidence interval (CI) were derived under the random-effects model. Results: A total of 27 independent studies including 2,868 participants were meta-analyzed. Significance was noted for intraoperative blood loss (WMD: -117.194, 95% CI: -170.188 to 64.201, P<0.001), harvested lymph nodes (WMD: -1.023, 95% CI: -1.776 to -0.269, P=0.008), postoperative hospital stay (WMD: -3.555, 95% CI: -4.509 to -2.601, P<0.001), postoperative morbidity (OR: 0.596, 95% CI: 0.407 to 0.871, P=0.008), overall survival rate at 2-year (OR: 1.524, 95% CI: 1.143 to 2.031, P=0.004), T2 survival at 1-year (OR: 1.799, 95% CI: 1.777 to 2.749, P<0.01) and 2-year (OR: 2.026, 95% CI: 1.392 to 2.949, P<0.001), as well as T3 survival at 1-year (OR: 2.669, 95% CI: 1.564 to 4.555, P<0.001) and 2-year (OR: 2.300, 95% CI: 1.308 to 4.046, P=0.004). Subgroup analyses revealed that ethnicity, incidental GBC, sample size, and follow-up period were possible sources of heterogeneity. There was a low probability of publication bias for all outcomes except postoperative morbidity. Conclusions: Our findings indicated that LS statistically had better 2-year survival rates, less intraoperative bleeding, shorter hospitalization times, and lower rates of complications than OS. However, the superiority and even the safety of LS still remain an open question due to the impact of incidental GBC, unaccounted heterogeneity, publication bias, lymph node dissection, and port-site metastasis.

Impact of Elevated Lipoprotein A on Clinical Outcomes in Patients Undergoing Percutaneous Coronary Intervention: A Systematic Review and Meta-analysis.

Lipoprotein(a) (Lp(a)) is an inherited lipoprotein particle associated with increased risk of atherosclerotic cardiovascular (CV) diseases. However, its impact on outcomes after percutaneous coronary intervention (PCI) remains unclear. The objective of this study was to assess the relationship between elevated Lp(a) levels and major adverse cardiovascular events (MACEs) and other outcomes in patients undergoing PCI. We systematically searched Embase, MEDLINE/PubMed, and Web of Science for studies published from 2015 to 2024 comparing CV outcomes between patients with elevated versus non-elevated Lp(a) levels after PCI. Primary outcome was MACE. Secondary outcomes included all-cause mortality, CV mortality, stroke, myocardial infarction, and revascularization. Risk ratios (RRs) were pooled using a random-effect model. Fifteen studies with 45,059 patients were included. Patients with elevated Lp(a) had a significantly higher risk of MACE (RR 1.38, 95% confidence interval (CI) 1.23-1.56). Elevated Lp(a) was also associated with increased risks of all-cause death (RR 1.26), CV death (RR 1.58), myocardial infarction (RR 1.44), revascularization (RR 1.38), and stroke (RR 1.18). Heterogeneity was considerable for some outcomes. This meta-analysis demonstrates that elevated Lp(a) levels are associated with worse CV outcomes, including higher rates of MACE, mortality, and recurrent ischemic events in patients undergoing PCI. Novel therapeutic approaches specifically targeting Lp(a) reduction may help mitigate residual CV risk in this high-risk population.

Endothelial Function Responses to Nigella sativa (Black Seed) Supplementation: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Nigella sativa (NS), commonly known as black cumin or black seed, is a medicinal plant with a rich history of traditional use in various cultures. Recent research has shed light on its potential therapeutic properties, particularly its effects on endothelial markers involved in inflammatory processes. This systematic review and meta-analysis evaluated the endothelial function responses, including intercellular adhesion molecule (ICAM) and vascular cell adhesion molecule (VCAM), to NS supplementation. We systematically searched Medline via PubMed, Scopus, Web of Science, and Embase databases from inception until August 5, 2023. Comparative randomized controlled trials (RCTs) were included. Pairwise meta-analysis was conducted using RevMan version 5.4 for Windows. Pooled data were reported as mean difference (MD), with their 95% confidence interval (CI). The present meta-analysis included three RCTs, which included 146 patients. The pooled random-effect size showed no difference between the NS group and the control group in terms of ICAM (MD = -59.32, 95% CI: -137.18 to 18.54; p = 0.14) and VCAM (MD = -200.1, 95% CI: -429.9 to 29.69; p = 0.09). The pooled data were severely heterogeneous. In conclusion, NS supplementation does not have a significant impact on the endothelial function of patients with CVD or the risks of CVD. Further comparative RCTs with larger sample sizes and more diverse populations are needed to establish the efficacy and safety of NS in different clinical settings.

The effectiveness of nurses' psychosocial interventions for sensory deprivation in intensive care patients: a systematic review and meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to assess the effectiveness of nurses' psychosocial interventions for addressing sensory deprivation in intensive care units (ICUs). MATERIALS AND METHODS: A comprehensive search of PubMed, Web of Science, EBSCOhost, Google Scholar, CINAHL, Embase, Cochrane Library, and YÖK Thesis Center databases was conducted from August 2023 to May 2024, without any temporal restrictions. In addition, a physical search was made in the university library for grey literature. RESULTS: The study revealed that nurses' psychosocial interventions significantly improved patients' level of consciousness (SMD = 1.042, %95 CI = 0.716 to 1.369; Z = 6.25; p < .05) and sleep quality in ICUs (SMD=1.21, 95% CI= 0.232 to 1.810; Z = 2.49; p < .05). The effectiveness of psychosocial interventions varied based on the type of intervention, patient age, ICU type, patient group, and intervention duration. Notably, auditory stimuli and aromatherapy demonstrated particularly high effect sizes, significantly enhancing patients' levels of consciousness and sleep quality. CONCLUSION: In conclusion, psychosocial interventions aimed at reducing sensory deprivation in intensive care units exert beneficial effects on individuals, notably enhancing their level of consciousness and improving sleep quality.

Impact of sarcopenia on outcomes following lumbar spine surgery for degenerative disease: an updated systematic review and meta-analysis.

PURPOSE: This study aimed to consolidate the evidence regarding the prognostic influence of sarcopenia in degenerative lumbar spine surgeries. METHODS: A literature search of public databases was conducted up to Nov 15, 2023 using combinations of the key words "sarcopenia" and "lumbar spine surgery". Eligible studies were those that focused on adults undergoing decompression or fusion surgery for degenerative lumbar spine diseases, and compared the outcomes between patients with and without preoperative sarcopenia. Primary outcomes were change in ODI and back and leg pain VAS pain scores. Secondary outcomes were changes in Eq. 5D, JOA, SFHS-p scores, and LOS. RESULTS: Ultimately, nine retrospective studies with a total of 993 patients were included. Sarcopenic patients exhibited significantly worse functional improvement as assessed by ODI compared to non-sarcopenic patients (pooled standardized mean difference [pSMD] = 0.53, 95% confidence interval [CI]: 0.17-0.90). Back pain (pSMD = 0.31, 95% CI:0.15-0.47) and leg pain (pSMD = 0.21, 95% CI:0.02 - 0.39) improvement were also less in sarcopenic patients. Non-sarcopenic patients had greater improvements in Eq. 5D (pSMD = 0.25) and SFHS-p (pSMD = 0.39), and shorter LOS (pSMD = 0.62). CONCLUSIONS: As compared to patients without sarcopenia, those with sarcopenia undergoing lumbar spine surgery for degenerative diseases have lower improvements in functional ability, quality of life, physical health, pain relief and extended hospitalization compared to those without sarcopenia.

The Effect of Subcutaneous Saline Irrigation on Wound Complications After Cesarean Section: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Subcutaneous (SC) saline irrigation was reported as a feasible and cost-effective procedure to prevent cesarean section (CS) surgical site complications. We aim to investigate the efficacy of SC saline irrigation to prevent CS surgical site complications. A systematic review and meta-analysis were conducted synthesizing evidence from randomized controlled trial (RCT) studies obtained from PubMed, Embase Cochrane, Scopus, and Web of Science from inception to March 2024. Pooled outcomes included wound complications (superficial surgical site infections (SSI), hematoma, seroma, and wound separation) and operative time. We used RevMan v.5.4. (The Cochrane Collaboration, Oxford, UK) to report dichotomous outcomes using risk ratio (RR) and continuous outcomes using mean differences (MD) with a 95% confidence interval (CI). Five RCTs with 4,025 patients were included. Four studies had a low overall risk of bias and only one trial with some concerns about selection bias. There was no difference between SC saline irrigation and no irrigation regarding the incidence of superficial SSI (five RCTs, RR: 0.72 with 95% CI [0.47, 1.10], P = 0.13), seroma (four RCTs, RR: 0.73 with 95% CI [0.32, 1.65], P = 0.45), wound separation (four RCTs, RR: 0.66 with 95% CI [0.36, 1.24], P = 0.2), and operative time (four RCTs, MD: -1.26 with 95% CI [-5.14, 2.62], P = 0.52). However, SC saline irrigation significantly decreased the incidence of hematoma (three RCTs, RR: 0.54 with 95% CI [0.45, 0.65], P = 0.00001). SC saline irrigation of the surgical site after CS was not effective in preventing the incidence of superficial SSI, seroma, or wound separation, while only preventing the incidence of hematoma.

Effects of Targeted Hypercapnia on Mortality and Length of Stay of Post-cardiac Arrest Patients: A Systematic Review and Meta-Analysis.

Therapeutic hypercapnia has been proposed as a potential strategy to enhance cerebral perfusion and improve outcomes in patients after cardiac arrest. However, the effects of targeted hypercapnia remain unclear. We conducted a systematic review and meta-analysis to evaluate the impact of hypercapnia compared to normocapnia on mortality and length of stay in post-cardiac arrest patients. We searched major databases for randomized controlled trials and observational studies comparing outcomes between hypercapnia and normocapnia in adult post-cardiac arrest patients. Data on in-hospital mortality and the ICU and hospital length of stay were extracted and pooled using random-effects meta-analysis. Five studies (two randomized controlled trials (RCTs) and three observational studies) with a total of 1,837 patients were included. Pooled analysis showed hypercapnia was associated with significantly higher in-hospital mortality compared to normocapnia (56.2% vs. 50.5%, OR 1.24, 95% CI 1.12-1.37, p<0.001). There was no significant heterogeneity (I2 = 25%, p = 0.26). No statistically significant differences were found for ICU length of stay (mean difference 0.72 days, 95% CI -0.51 to 1.95) or hospital length of stay (mean difference 1.13 days, 95% CI -0.67 to 2.93) between the groups. Sensitivity analysis restricted to mild hypercapnia studies did not alter the mortality findings. This meta-analysis did not find a mortality benefit with targeted hypercapnia compared to normocapnia in post-cardiac arrest patients. The results align with current guidelines recommending a normal partial pressure of arterial carbon dioxide (PaCO2) target range and do not support routinely targeting higher carbon dioxide levels in this setting.

Efficacy of specific exercises in general population with non-specific low back pain: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: Localized exercises are employed to activate, train, or restore the function of particular muscles and they are usually considered as part of treating individuals suffering low back pain. So, this systematic review and meta-analysis aimed to assess the efficacy of specific exercises in general population with non-specific low back pain (LBP). METHODS: We conducted electronic searches in MEDLINE/PubMed, Scopus, Web of Science (WoS), and Google scholar from January 1990 to June 2021. Initially, 47,740 records were identified. Following the removal of duplicates, 32,138 records were left. After reviewing titles and abstracts, 262 papers were chosen for thorough assessment. Among these, 208 studies were excluded, resulting in 54 trials meeting the inclusion criteria for this study. Additionally, 46 of these trials were randomized controlled trials and were further evaluated for the meta-analysis. We included trials investigating the effectiveness of exercise therapy, including isometric activation of deep trunk muscles, strengthening exercises, stabilization exercises, stretching exercises, and proprioceptive neuromuscular facilitation exercises (PNF) in LBP patients. The primary outcome was pain intensity, measured using tools such as the visual analogue scale (VAS) and numeric pain rating scale (NPRS). The secondary outcome was disability, assessed through instruments such as the Roland Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI). The quality of the eligible studies was assessed using the Verhagen tool, and the level of evidence was evaluated using the GRADE approach. RESULTS: Based on the Verhagen tool, 46 trials (85.2%) were categorized as having low methodological quality, while 8 studies (14.8%) were considered to have medium methodological quality. The meta-analysis indicated a small efficacy in favor of isometric activation of deep trunk muscles (-0.37, 95% CI: -0.88 to 0.13), a moderate efficacy in favor of stabilization exercises (-0.53, 95% CI: -1.13 to 0.08), and a large efficacy in favor of PNF exercises (-0.91, 95% CI: -1.62 to -0.2) for reducing pain intensity as assessed by VAS or NPRS tools. Moreover, the meta-analysis revealed a moderate efficacy for isometric activation of deep trunk muscles (-0.61, CI: -1.02 to -0.19), and a large efficacy for PNF exercises (-1.26, 95% CI: -1.81 to -0.72) in improving disability, assessed using RMDQ or ODI questionnaires. The level of certainty in the evidence, as determined by the GRADE approach, was very low to low. CONCLUSION: These findings emphasize the importance of incorporating localized therapeutic exercises as a fundamental aspect of managing non-specific LBP. Clinicians should consider utilizing localized therapeutic exercise tailored to individual patient needs. Furthermore, further research investigating optimal exercise therapy, optimal dose of the exercises, durations, and long-term adherence is warranted to enhance the precision and efficacy of exercise-based interventions for non-specific LBP.
