Background: Liver transplant is frequently performed at night due to the unpredictability of organ procurement and reduction of Cold Ischemia Time (CIT). Previous study reported a doubled mortality Hazard Ratio (HR) of early death and increased postoperative complications in nighttime liver transplant. This study aims to evaluate the impact of nighttime operation on patients’ survival and postoperative complications by using meta-analysis. Methods: We performed a systematic review of the PubMed database and identified five eligible studies. Three time points (30 days, 90 days and 1 year) were explored in patients’ survival by using pooled HR. Four types of postoperative complications (vascular, biliary tract, wound and primary graft non-function) were investigated by using pooled Odds Ratio (OR). Publication bias was also performed. Results: Our study results were contradicting with the previous report and yielded no significant difference with a HR=0.98 (95% CI=0.89-1.06) on 30 days, HR=1.12 (95% CI=0.89-1.35) on 90 days and HR=1.07 (95% CI=0.95-1.18) on 1 year in nighttime procedure. Consistent with the result of patients’ survival, no significant result was found in postoperative complications evaluation as well. None of the four complications demonstrated significant result. And we failed to detect any significant publication bias. Conclusions: Based on current evidence, nighttime liver transplantations do not degrade patients’ survival or increase postoperative complications risk compared with daytime operations.

“…One of the main forms of CVD is myocardial ischemia, which can be defined as heart muscle failure, due to insufficient blood supply. This renders CVD management and detection essential tasks for the advanced prevention, recognition, and treatment of CVDs [2]. During 2019, ischemic heart disease led to 8.9 million deaths [2].…”

Cardiovascular Disease (CVD) is a primary cause of heart problems such as angina and myocardial ischemia. The detection of the stage of CVD is vital for the prevention of medical complications related to the heart, as they can lead to heart muscle death (known as myocardial infarction). The electrocardiogram (ECG) reflects these cardiac condition changes as electrical signals. However, an accurate interpretation of these waveforms still calls for the expertise of an experienced cardiologist. Several algorithms have been developed to overcome issues in this area. In this study, a new scheme for myocardial ischemia detection with multi-lead long-interval ECG is proposed. This scheme involves an observation of the changes in ischemic-related ECG components (ST segment and PR segment) by way of the Choi-Williams time-frequency distribution to extract ST and PR features. These extracted features are mapped to a multi-class SVM classifier for training in the detection of unknown conditions to determine if they are normal or ischemic. The use of multi-lead ECG for classification and 1 min intervals instead of beats or frames contributes to improved detection performance. The classification process uses the data of 92 normal and 266 patients from four different databases. The proposed scheme delivered an overall result with 99.09% accuracy, 99.49% sensitivity, and 98.44% specificity. The high degree of classification accuracy for the different and unknown data sources used in this study reflects the flexibility, validity, and reliability of this proposed scheme. Additionally, this scheme can assist cardiologists in detecting signal abnormality with robustness and precision, and can even be used for home screening systems to provide rapid evaluation in emergency cases.

“…There is evidence that other holidays may be associated with the risk of myocardial infarction. 1 , 2 , 3 Both Christmas and New Year's Eve are associated with a higher rate of myocardial infarction in Sweden. 1 Similarly, the number of myocardial infarction hospitalizations appears to be greater during Islamic holidays, 2 and researchers have observed an excess of deaths due to myocardial infarction on Chinese holidays.…”

“… 1 Similarly, the number of myocardial infarction hospitalizations appears to be greater during Islamic holidays, 2 and researchers have observed an excess of deaths due to myocardial infarction on Chinese holidays. 3 The relationship of myocardial infarction with Valentine's Day, however, has not been studied. Ischemic heart disease is a leading cause of death, and excessive food and alcohol, or stress associated with holidays, may influence the risk of acute myocardial infarction.…”

Matters of the Heart: Case-Crossover Analysis of Myocardial Infarction on Valentine's Day

We studied the risk of myocardial infarction on Valentine's Day. We conducted a case-crossover study of 51,450 adults with myocardial infarctions in February, 1989-2019. The exposure was Valentine's Day, and the 2 days before and after Valentine's Day. We estimated odds ratios (OR) to compare days when myocardial infarction occurred with neighboring control days. Compared with other days, Valentine's Day was associated with lower odds of myocardial infarction the following day for men (OR 0.91, 95% confidence interval 0.85-0.98), but not for men and women combined (OR 0.95, 95% confidence interval 0.91-1.01). Risk of myocardial infarction in men is lower the day after Valentine's Day.
