Meta-Analysis
Background: Septic shock is a distributive shock with decreased systemic vascular resistance and MAP. Septic shock contributes to the most common causes of death in the intensive care unit (ICU). Current guidelines recommend the use of norepinephrine as the first-line vasopressor, whereas adrenergic agonists and vasopressin analogs are also commonly used by physicians. To date, very few studies have synthetically compared the effects of multiple types of vasoactive medications. The aim of this study was to systemically evaluate the efficacy of vasoactive agents both individually and in combination to treat septic shock. Methods: The PubMed, MEDLINE, Embase, Web of Science, and Cochrane Central Register for Controlled Trials (CENTRAL) were searched up to May 12, 2022, to identify relevant randomized controlled trials. A network meta-analysis was performed to evaluate the effect of different types of vasopressors. The primary outcome was 28-day all-cause mortality. The secondary outcome was the ICU length of stay. Adverse events are defined as any undesirable outcomes, including myocardial infarction, cardiac arrhythmia, peripheral ischemia, or stroke and cerebrovascular events. Findings: Thirty-three randomized controlled trials comprising 4,966 patients and assessing 8 types of vasoactive treatments were included in the network meta-analysis. The surface under the cumulative ranking curve provided a ranking of vasoactive medications in terms of 28-day all-cause mortality from most effective to least effective: norepinephrine plus dobutamine, epinephrine, vasopressin, terlipressin, norepinephrine, norepinephrine plus vasopressin, dopamine, and dobutamine. Dopamine was associated with a significantly shorter ICU stay than norepinephrine, terlipressin, and vasopressin, whereas other vasoactive medications showed no definite difference in ICU length of stay. Regarding adverse events, norepinephrine was associated with the highest incidences of myocardial infarction and peripheral ischemia. Dopamine was associated with the highest incidence of cardiac arrhythmia. Epinephrine and terlipressin were associated with the highest incidences of myocardial infarction and peripheral ischemia. Interpretation: The results of this network meta-analysis suggest that norepinephrine plus dobutamine is associated with a lower risk of 28-day mortality in septic shock patients than other vasoactive medications, and the use of dopamine is associated with a higher risk of 28-day mortality due to septic shock than norepinephrine, terlipressin, and vasopressin.

Meta-Analysis
BACKGROUND
Short-term (≤6 months) dual antiplatelet therapy (DAPT) and DAPT de-escalation become attractive for patients with acute coronary syndrome.
METHODS
A systemic search identified randomized controlled trials that included patients with acute coronary syndrome treated using (1) standard DAPT (12 months) with clopidogrel, prasugrel (standard/low dose), or ticagrelor; (2) extended DAPT (≥18 months); (3) short-term DAPT (≤6 months) followed by P2Y inhibitor or aspirin; (4) 12-month DAPT with unguided de-escalation from potent P2Y inhibitors to low-dose potent P2Y inhibitor or clopidogrel at 1 month; and (5) guided selection DAPT with genotype or platelet function tests. The primary efficacy outcome (major adverse cardiovascular events) was a composite of cardiovascular death, myocardial infarction, or stroke. The primary safety outcome was major or minor bleeding.
RESULTS
This meta-analysis included 32 randomized controlled trials with 103 497 patients. While there were no differences in efficacy between short, unguided de-escalation and guided selection strategies, unguided de-escalation was associated with reduced risk of major adverse cardiovascular events compared with standard DAPT with clopidogrel or ticagrelor (hazard ratio [95% CI], 0.67 [0.49-0.93] and 0.68 [0.50-0.93]). Both short DAPT followed by P2Y inhibitor and unguided de-escalation were associated with reduced risks in safety compared with other strategies, including guided selection (hazard ratio [95% CI], 0.66 [0.47-0.93] and 0.48 [0.33-0.71]). Short DAPT followed by a P2Y inhibitor was associated with reduced risk of major bleeding and all-cause death compared with standard, extended DAPT (eg, versus DAPT with clopidogrel; hazard ratio [95% CI], 0.64 [0.42-0.97] and 0.60 [0.44-0.82]). By rankogram, unguided de-escalation strategy was the safest and most effective strategy in reducing major adverse cardiovascular events and major or minor bleeding while short DAPT followed by P2Y inhibitor was ranked the best for major bleeding and all-cause death.
CONCLUSIONS
In patients with acute coronary syndrome, unguided de-escalation was associated with the lowest risk of major adverse cardiovascular events and major or minor bleeding outcomes, while short DAPT followed by P2Y inhibitor was associated with the lowest risk of major bleeding and all-cause death.

Meta-Analysis
Endometriosis is a common disease affecting 10% of reproductive-age women globally and is associated with chronic systemic inflammation. Some studies suggest that women with endometriosis have a higher risk of cardiovascular disease, whereas others have conflicting findings. This study aims to further investigate the association between endometriosis and cardiovascular disease. A systematic review was conducted using the EMBASE and MEDLINE databases from inception to October 2022. The search strategy comprised terms for "endometriosis" and "cardiovascular disease." Eligible studies had to include one group of patients with endometriosis and another group of individuals without endometriosis. The study must then compare the incidence or prevalence of cardiovascular disease (major adverse cardiovascular events [MACE], ischemic heart disease [IHD], cerebrovascular accident [CVA], or peripheral artery disease [PAD]). A total of 5,401 articles were identified, and 9 studies were eligible for meta-analysis. Pooled analysis showed an increased prevalence of IHD (pooled odds ratio [OR]: 1.22; 95% confidence interval [95% CI]: 0.74-2.02), CVA (pooled OR: 1.28; 95% CI: 1.07-1.53), and PAD (pooled OR: 1.55; 95% CI: 1.35-1.78). Pooled analysis showed an increased incidence of MACE (pooled hazard ratio [HR]: 1.23; 95% CI: 1.14-1.33), IHD (pooled HR: 1.43; 95% CI: 1.28-1.59), and CVA (pooled HR: 1.20; 95% CI: 1.11-1.30). This systematic review and meta-analysis found a statistically significant association between endometriosis and increased risk of cardiovascular disease (MACE, IHD, CVA, PAD).

BACKGROUND
This publication represents a scheduled update of the 2019 guidelines of the International Working Group of the Diabetic Foot (IWGDF) addressing the use of systems to classify foot ulcers in people with diabetes in routine clinical practice. The guidelines are based on a systematic review of the available literature that identified 28 classifications addressed in 149 articles and, subsequently, expert opinion using the GRADE methodology.
METHODS
First, we have developed a list of classification systems considered as being potentially adequate for use in a clinical setting, through the summary of judgements for diagnostic tests, focussing on the usability, accuracy and reliability of each system to predict ulcer-related complications as well as use of resources. Second, we have determined, following group debate and consensus, which of them should be used in specific clinical scenarios. Following this process, in a person with diabetes and a foot ulcer we recommend: (a) for communication among healthcare professionals: to use the SINBAD (Site, Ischaemia, Bacterial infection, Area and Depth) system (first option) or consider using WIfI (Wound, Ischaemia, foot Infection) system (alternative option, when the required equipment and level of expertise is available and it is considered feasible) and in each case the individual variables that compose the systems should be described rather than a total score; (b) for predicting the outcome of an ulcer in a specific individual: no existing system could be recommended; (c) for characterising a person with an infected ulcer: the use of the IDSA/IWGDF classification (first option) or consider using the WIfI system (alternative option, when the required equipment and level of expertise is available and it is considered as feasible); (d) for characterising a person with peripheral artery disease: consider using the WIfI system as a means to stratify healing likelihood and amputation risk; (e) for the audit of outcome(s) of populations: the use of the SINBAD score.
CONCLUSIONS
For all recommendations made using GRADE, the certainty of evidence was judged, at best, as being low. Nevertheless, based on the rational application of current data this approach allowed the proposal of recommendations, which are likely to have clinical utility.

Meta-Analysis Review
BACKGROUND
Recent studies have shown that breast arterial calcification (BAC) detected on screening mammography is linked to cardiovascular diseases via medial calcification. However, its effect on cardiovascular outcomes remains unclear. Therefore, we conducted a meta-analysis to determine the effect of BAC on cardiovascular outcomes in patients.
METHODS
Three electronic databases (Pubmed, Embase, and Scopus) were searched on May 1, 2022, for studies examining the relationship between BAC and cardiovascular outcomes including cardiac death, acute myocardial infarction, ischemic heart disease, stroke, peripheral artery disease, and heart failure. A random-effects meta-analysis model was used to summarise the studies.
RESULTS
A total of 5 longitudinal studies were included with a combined cohort of 87,865 patients. Significantly, the pooled risk ratio (RR) of the association between BAC and cardiac death was 2.06 (P < 0.00001). BAC was associated with a significantly increased risk of developing other cardiovascular diseases, such as ischemic/hemorrhagic stroke (RR 1.51; P = 0.003), ischemic stroke (RR 1.82; P < 0.00001), peripheral vascular disease (RR 1.24; P = 0.003), and heart failure (RR 1.84; P < 0.00001). There was no significant relationship for developing myocardial infarction or for total cardiovascular diseases.
CONCLUSIONS
Our findings suggest that BAC was associated with an increased risk of cardiovascular mortality, and certain cardiovascular outcomes. There is thus a potential to use BAC as a sex-specific cardiovascular risk assessment tool. Furthermore, there is a need for more widespread reporting of BAC to better understand the pathophysiologic mechanisms behind its correlation with cardiovascular disease and to apply it in clinical practice.

INTRODUCTION
Heatstroke (HS) is a severe form of heat-related illness (HRI) associated with high morbidity and mortality, representing a condition that includes long-term multiorgan dysfunction and susceptibility to further heat illness.
METHODS
In a systematic review searching Medline PubMed from the studies conducted between 2009 and 2020, 16 papers were identified.
RESULTS
A hallmark symptom of heat stroke is CNS dysfunction (a hallmark sign of HS) which manifests as mental status changes, including agitation, delirium, epilepsy, or coma at the time of the collapse. Acute kidney injury (AKI), gut ischemia, blood clots in the stomach and small intestine, cytoplasmic protein clumps in the spleen, and injury of skeletal muscle (rhabdomyolysis) are all characteristics of peripheral tissue damage. Severe heat stroke tends to be complicated by rhabdomyolysis, especially in patients with exertional heat stroke. Rhabdomyolysis may lead to systemic effects, including the local occurrence of compartment syndrome, hyperkalemic cardiac arrest, and/or lethal disseminated intravascular coagulopathy. Untreated heat stroke might exacerbate psychosis, lactic acidosis, consumptive coagulopathy, hematuria, pulmonary edema, renal failure, and other metabolic abnormalities. Core body temperature and level of consciousness are the most significant indicators to diagnose the severity of heat stroke and prevent unfavorable consequences. Heatstroke is a life-threatening illness if not promptly recognized and effectively treated.
DISCUSSION
This review highlighted that core body temperature and white blood cell count are significant contributing factors affecting heat stroke outcomes. Other factors contributing to the poor outcome include old age, low GCS, and prolonged hospital stay. The prevalence of both classic and exertional heatstroke can be reduced by certain simple preventive measures, such as avoiding strenuous activity in hot environments and reducing exposure to heat stress.

Review
BACKGROUND
Perinatal stroke refers to a diverse but specific group of cerebrovascular diseases that occur between 20 weeks of fetal life and 28 days of postnatal life. Acute treatment options for perinatal stroke are limited supportive care, such as controlling hypoglycemia and seizures. Stem cell-based therapies offer a potential therapeutic approach to repair, restore, or regenerate injured brain tissue. Preclinical findings have culminated in ongoing human neonatal studies.
OBJECTIVES
To evaluate the benefits and harms of stem cell-based interventions for the treatment of stroke in newborn infants compared to control (placebo or no treatment) or stem-cell based interventions of a different type or source.
SEARCH METHODS
We searched CENTRAL, PubMed, Embase, and three trials registries in February 2023. We planned to search the reference lists of included studies and relevant systematic reviews for studies not identified by the database searches.
SELECTION CRITERIA
We attempted to include randomized controlled trials, quasi-randomized controlled trials, and cluster trials that evaluated any of the following comparisons. • Stem cell-based interventions (any type) versus control (placebo or no treatment) • Mesenchymal stem/stromal cells (MSCs) of a specifictype (e.g. number of doses or passages) or source (e.g. autologous/allogeneic or bone marrow/cord) versus MSCs of another type or source • Stem cell-based interventions (other than MSCs) of a specific type (e.g. mononuclear cells, oligodendrocyte progenitor cells, neural stem cells, hematopoietic stem cells, or induced pluripotent stem cell-derived cells) or source (e.g. autologous/allogeneic or bone marrow/cord) versus stem cell-based interventions (other than MSCs) of another type or source • MSCs versus stem cell-based interventions other than MSCs We planned to include all types of transplantation regardless of cell source (bone marrow, cord blood, Wharton's jelly, placenta, adipose tissue, peripheral blood), type of graft (autologous or allogeneic), and dose.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were all-cause neonatal mortality, major neurodevelopmental disability, and immune rejection or any serious adverse event. Our secondary outcomes included all-cause mortality prior to first hospital discharge, seizures, adverse effects, and death or major neurodevelopmental disability at 18 to 24 months of age. We planned to use GRADE to assess the certainty of evidence for each outcome.
MAIN RESULTS
We identified no completed or ongoing randomized trials that met our inclusion criteria. We excluded three studies: two were phase 1 trials, and one included newborn infants with conditions other than stroke (i.e. cerebral ischemia and anemia). Among the three excluded studies, we identified the first phase 1 trial on the use of stem cells for neonatal stroke. It reported that a single intranasal application of bone marrow-derived MSCs in term neonates with a diagnosis of perinatal arterial ischemic stroke (PAIS) was feasible and apparently not associated with severe adverse events. However, the trial included only 10 infants, and follow-up was limited to three months.
AUTHORS' CONCLUSIONS
No evidence is currently available to evaluate the benefits and harms of stem cell-based interventions for treatment of stroke in newborn infants. We identified no ongoing studies. Future clinical trials should focus on standardizing the timing and method of cell delivery and cell processing to optimize the therapeutic potential of stem cell-based interventions and safety profiles. Phase 1 and large animal studies might provide the groundwork for future randomized trials. Outcome measures should include all-cause mortality, major neurodevelopmental disability and immune rejection, and any other serious adverse events.

Meta-Analysis
BACKGROUND
Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor is a standard therapy in patients with ischemic vascular diseases (IVD) including coronary artery, cerebrovascular and peripheral arterial diseases, although the optimal duration of this treatment is still debated. Previous meta-analyses reported conflicting results about the effects of long-term and short-term as well as non-DAPT use in various clinical settings. Herein, we conducted a comprehensive meta-analysis to assess the efficacy and safety of different durations of DAPT.
METHODS
We reviewed relevant articles and references from database, which were published prior to April 2023. Data from prospective studies were processed using RevMan5.0 software, provided by Cochrane Collaboration and transformed using relevant formulas. The inclusion criteria involved randomization to long-term versus short-term or no DAPT; the endpoints included at least one of total or cardiovascular (CV) mortalities, IVD recurrence, and bleeding.
RESULTS
A total of 34 randomized studies involving 141 455 patients were finally included. In comparison with no or short-term DAPT, long-term DAPT reduced MI and stroke, but did not reduce the total and CV mortalities. Meanwhile, bleeding events were increased, even though intracranial and fatal bleedings were not affected. Besides, the reduction of MI and stroke recurrence showed no statistical significance between long-term and short-term DAPT groups.
CONCLUSION
Long-term DAPT may not reduce the mortality of IVD besides increasing bleeding events, although reduced the incidences of MI and stroke early recurrence to a certain extent and did not increase the risk of fatal intracranial bleeding.

Meta-Analysis Review
Sacubitril-valsartan is an angiotensin receptor-neprilysin inhibitor (ARNI) associated with a decreased risk of death and hospitalization for selected patients with heart failure (HF). However, its association with improved atherosclerotic cardiovascular disease (ASCVD) events remains unclear. We performed a meta-analysis to evaluate the association of ARNI with ASCVD events in patients with HF. We systematically searched PubMed, Embase, Cochrane, and ClinicalTrials.gov for studies comparing ARNIs with angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) in terms of myocardial infarction, stroke, angina pectoris, peripheral artery disease, and the composite end point in patients with HF. A total of 8 randomized controlled trials were included, with 17,541 patients assigned to either the ARNI (8,764 patients) or ACEi/ARB (8,777 patients) groups. The incidence of composite end point (risk ratio [RR] 1.03, 95% confidence interval [CI] 0.93 to 1.13, p = 0.63), myocardial infarction (RR 1.02, 95% CI 0.81 to 1.30, p = 0.85), angina pectoris (RR 0.96, 95% CI 0.80 to 1.17, p = 0.70), and stroke (RR 0.99, 95% CI 0.85 to 1.16, p = 0.93) were not statistically different between the ARNI and ACEi/ARB groups. However, ARNI was associated with a higher incidence of peripheral artery disease (RR 1.63, 95% CI 1.05 to 2.52, p = 0.03). In conclusion, this meta-analysis found no association between ARNI therapy and improved ASCVD events in patients with HF.

Review
OBJECTIVE
Both bypass surgery and endovascular treatment are well-recognized interventions for the treatment of peripheral artery disease; however, the effect of failed endovascular treatment on subsequent surgeries remains controversial. A systematic review was conducted to compare the outcomes of primary bypass and bypass surgery after endovascular treatment.
METHODS
Three academic databases (Embase, PubMed, and Scopus) were searched from their inception to August 2022. Two independent investigators searched for studies that reported the outcomes of primary bypass surgery and bypass surgery after endovascular treatment in patients with peripheral artery disease. Abstracts and full-text studies were screened independently using duplicate data abstraction. Dichotomous outcome measures were reported using a random-effects model to generate a summary odds ratio (OR) and 95% confidence interval (CI). The risk of bias was assessed using the Newcastle-Ottawa Scale.
RESULTS
Seventeen retrospective observational studies were selected from 3911 articles and included 8064 patients, 6252 of whom underwent primary bypass surgery and 1812 underwent bypass surgery after endovascular treatment. The mean age was 69.0 years and 61.2% (n = 4938) were male. For perioperative outcomes, the 30-day results showed no difference in mortality (OR, 0.76; 95% CI, 0.53-1.10), or amputation (OR, 0.89; 95% CI, 0.67-1.20). For short- to mid-term outcomes, primary patency did not differ at 6 months (OR, 0.98; 95% CI, 0.81-1.19), 1 year (OR, 1.12; 95% CI, 0.97-1.30), or 2 years (OR, 1.17; 95% CI, 0.85-1.61) follow-up. Amputation-free survival did not differ at 6 months (OR, 1.03; 95% CI, 0.82-1.30), 1 year (OR, 1.09; 95% CI, 0.89-1.32), 2 years (OR, 1.18; 95% CI, 0.93-1.50), or 3 years (OR, 1.09; 95% CI, 0.84-1.40) of follow-up. No significant difference was found in overall survival or second patency.
CONCLUSIONS
This meta-analysis of retrospective, nonrandomized, observational studies suggests that prior endovascular treatment of lower extremity arterial disease does not result in worse perioperative, short-term, or mid-term clinical outcomes of subsequent infrainguinal bypass surgery compared with patients without prior endovascular treatment.
