Abstract Background: The association between the lymphocyte-to-monocyte ratio (LMR) and prognosis in the patients with acute coronary syndrome (ACS) is not fully understood. We performed this systematic review and meta-analysis to evaluate the correlation between LMR and mortality or major adverse cardiac events (MACE) in patients with ACS.Methods: A systematic search was performed in PubMed, MEDLINE, EMBASE, the Cochrane Library, Scopus, and Web of science. The association between LMR and mortality/MACE was analyzed in patients with ACS. The search was updated to April 15, 2020. Results: A total of 5 studies comprising 4343 patients were included in this meta-analysis. The results showed that lower LMR predicted higher short-term mortality/MACE (hazard ratio [HR] = 3.44, 95% confidence interval [CI]: 1.46–8.14, P < 0.05) and long-term mortality/MACE (HR = 1.70, 95% CI: 1.36– 2.13, P < 0.05). In the subgroup analysis, there was still statistical significance of long-term mortality/MACE in all subgroups.Conclusions: This study suggested that lower LMR value might be associated with higher short-term and long-term mortality/MACE in ACS patients. Especially for younger ACS patients, low LMR was more closely associated with poor prognosis.

The association between LMR and mortality or MACE was analyzed in patients with ACS. The search was updated to August 1, 2019.Results A total of 5 studies comprising 3122 patients were included in this meta-analysis. The results showed that lower LMR predicted short-term mortality/MACE (odds ratio [OR] = 2.61, 95% confidence interval [CI]: 1.15–5.94, P = 0.022) and higher long-term mortality/MACE (OR = 2.10, 95% CI: 1.06–4.19, P = 0.035). According to our subgroup analysis, there still has a statistical significance for LMR predict short-term mortality/MACE in lager sample size researches (≥600, OR = 3.50, 95% CI: 1.84–6.67, p < 0.001),Turkey researches (OR = 4.16, 95% CI: 2.32–7.46, p < 0.001), younger patients researches (< 62, OR = 3.76, 95% CI: 2.29–6.18, p < 0.001).Conclusions This study suggested that lower LMR value might be associated with higher short-term mortality/MACE and long-term mortality/MACE in patients with ACS.

Objective: In year 2016, quick Sepsis-Related Organ Failure Assessment (qSOFA) was introduced as a better sepsis screening tool compared to systemic inflammatory response syndrome (SIRS). The purpose of this systematic review and meta-analysis is to evaluate the ability of the qSOFA in predicting short- and long-term mortality among patients outside the intensive care unit setting. Method: Studies reporting on the qSOFA and mortality from MEDLINE (published between 1946 and 15th December 2017) and SCOPUS (published before 15th December 2017). Hand-checking of the references of relevant articles was carried out. Studies were included if they involved inclusion of patients presenting to the ED; usage of Sepsis-3 definition with suspected infection; usage of qSOFA score for mortality prognostication; and written in English. Study details, patient demographics, qSOFA scores, short-term (<30 days) and long-term (≥30 days) mortality were extracted. Two reviewers conducted all reviews and data extraction independently. Results and Discussion: A total of 39 studies met the selection criteria for full text review and only 36 studies were inclided. Data on qSOFA scores and mortality rate were extracted from 36 studies from 15 countries. The pooled odds ratio was 5.5 and 4.7 for short-term and long-term mortality respectively. The overall pooled sensitivity and specificity for the qSOFA was 48% and 85% for short-term mortality and 32% and 92% for long-term mortality, respectively. Studies reporting on short-term mortality were heterogeneous (Tau=24%, I2=94%, P<0.001), while long-term mortality studies were homogenous (Tau=0%, I2<0.001, P=0.52). The factors contributing to heterogeneity may be wide age group, various clinical settings, variation in the timing of qSOFA scoring, and broad range of clinical diagnosis and criteria. There was no publication bias for short-term mortality analysis. Conclusion: qSOFA score showed a poor sensitivity but moderate specificity for both short and long-term mortality prediction in patients with suspected infection. qSOFA score may be a cost-effective tool for sepsis prognostication outside of the ICU setting.

Abstract Biochemical remission after transsphenoidal surgery is still unsatisfied in acromegaly patients with macroadenomas, especially with invasive macroadenomas. Concerning the impact of preoperative somatostatin analogues (SSAs) on surgical outcomes, previous studies with limited cases reported conflicting results. To assess current evidence of preoperative medical treatment, we performed a systematic review and meta-analysis of comparative studies. A literature search was conducted in Pubmed, Embase, and the Cochrane Library. Five randomized controlled trials (RCT) and seven non-RCT comparative studies were included. These studies mainly focused on pituitary macroadenomas though a small number of microadenoma cases were included. For safety, preoperative SSAs were not associated with elevated risks of postoperative complications. With respect to efficacy, the short-term cure rate was improved by preoperative SSAs, but the long-term cure rate showed no significant improvement. For invasive macroadenomas, the short-term cure rate was also improved, but the long-term results were not evaluable in clinical practice because adjuvant therapy was generally required. In conclusion, preoperative SSAs are safe in patients with acromegaly, and the favorable impact on surgical results is restricted to the short-term cure rate in macroadenomas and invasive macroadenomas. Further well-designed RCTs to examine long-term results are awaited to update the finding of this meta-analysis.

Introduction Acute coronary syndrome (ACS) patients residing in rural areas are predisposed to higher risk of poor outcomes due to substantial delays in disease management, emphasising the importance of emerging telecardiology technologies in delivering emergency services in such settings. This meta-analysis aimed to investigate the impacts of prehospital telecardiology strategies on the clinical outcomes of rural ACS patients. Methods A literature search was performed of articles published up to April 2020 through six databases. Included studies were assessed for bias risk using the ROBINS-I tool, and a random-effects model was utilised to estimate effect sizes. Certainty of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE). Results Twelve studies with a total of 3989 patients were included in this review. Prehospital telecardiology in the form of tele-electrocardiography (tele-ECG) enabled prompt diagnosis and triage, resulting in a decreased door-to-balloon (DTB) time (mean difference = –25.53 minutes, 95% confidence interval (CI) –36.08 to –14.97 minutes; I2 = 98%), as well as lower in-hospital mortality (odds ratio (OR) = 0.57, 95% CI 0.36–0.92) and long-term mortality (OR = 0.52, 95% CI 0.39–0.69) rates, both with negligible heterogeneity ( I2 = 0%). GRADE assessment yielded very low to moderate certainty of evidence. Conclusion Prehospital tele-ECG appeared to be an effective and worthwhile approach in the management of rural ACS patients, as shown by moderate quality evidence on lower long-term mortality. Given the uncertainties of the evidence quality on DTB time and in-hospital mortality, future studies with a higher quality of evidence are required to confirm our findings.
