Survival rates for breast cancer (BC) are often based on the outcomes of this disease. The aim of this study was to compare the performance of three survival models, namely Cox regression, Aalen's, and Lin and Ying's additive hazards (AH) models for identifying the prognostic factors regarding the survival time of BC patients. ⋯ AH model may yield new insights in prognostic studies of survival time of patients with BC over time. Because of the positive slope of estimated cumulative regression function in Aalen's plot, metastasis, higher age at diagnosis, and high number of lymph nodes are important factors in reducing the survival BC, and then based on these factors, the therapists should consider a special therapeutic protocol for BC patients.

Pathogenesis of cardiovascular diseases (CVDs) may be indicated by lipoprotein-associated phospholipase A2 (Lp-PLA2), serving as an inflammatory biomarker. However, the general dietary predictors of Lp-PLA2 have not been investigated so far. The aim of the present study is to investigate the relationship between the serum levels of Lp-PLA2 and dietary patterns in adults with cardiovascular risk factors. ⋯ It can be concluded that the Western dietary pattern is associated with higher Lp-PLA2 levels. We recommend that adults eat less carbonated drinks, fast foods, salty snacks, mayonnaise, and organ meat to counteract increased serum Lp-PLA2 levels, which are directly associated with vascular inflammation and CVDs.

The artificial intelligence field is obtaining ever-increasing interests for enhancing the accuracy of diagnosis and the quality of patient care. Deep learning neural network (DLNN) approach was considered in patients with brain stroke (BS) to predict and classify the outcome by the risk factors. ⋯ The best means for dropping the BS load is effective BS prevention. DLNN strategy showed a surprising presentation in the prediction of BS mortality based on the main risk factors with an excellent diagnostic accuracy. Moreover, the time interval after 10 years, age, the history of hyperlipoproteinemia, and education level are the most important predictors for BS.

Inflammation is an important mechanism in the pathogenesis of delirium. Since delirium might reduce by anti-inflammatory effects of omega-3 fatty acids. Based on this respect, a study was conducted to indicate the effect of omega-3 fatty acids in the prevention of delirium in mechanically ventilated patients. ⋯ Omega-3 fatty acids can reduce the risk of delirium in mechanically ventilated patients.

There are no studies on the trend of gastric cancer (GC) incidence in Kurdistan, a province in the west of Iran. We aimed to estimate the trend, age-standardized incidence rate (ASR), and annual percentage change (APC) of GC in this province during 2001-2014. ⋯ The incidence of GC showed nonsignificant and significant decreasing trends in women and men in Kurdistan province, respectively. Despite such decreasing trends, the Kurdistan province is still considered as one of the regions with high incidence of GC in Iran. Therefore, it is necessary to implement screening programs in the province to early diagnose GC.
