AbstractWorldwide breast cancer is the leading cause of cancer related death in women. Paclitaxel is an effective drug used for the treatment of breast cancer but it has many side effects. Nab-paclitaxel (nanoparticle albumin-bound paclitaxel) is an FDA approved drug for the treatment of breast cancer. Currently many clinical trials are conducted to deliver nab-paclitaxel into the tumor cells. But the efficacy and safety of this nab-paclitaxel over conventional paclitaxel still remains questionable. So, we performed a meta-analysis to evaluate the efficacy and safety of nab-paclitaxel in breast cancer treatment.Electronic databases were searched for the suitable studies using key terms “nab-paclitaxel”, “paclitaxel”, and “clinical trial” with the combination of “breast cancer” up to August 11, 2019. Risk ratio (RR) and odds ratio (OR) with corresponding 95% confidence intervals (CIs) were calculated. All statistical analyses were performed by the Open Meta-Analyst program. A total of eight studies which fulfilled our criteria were included in this study. For efficacy we retrieved data of 12 months progression free survival, 24 months progression free survival, and overall survival (up to 3 years) and for the safety we took data of nausea, anemia, leukopenia, neutropenia, fatigue, diarrhea and pain.We did not found any difference in efficacy of nab-paclitaxel over paclitaxel (12 months progression free survival-RRFE= 0.86, 95%CI= 0.77-0.97, p= 0.02, I2= 25.07%; 24 months progression free survival-RRFE= 0.86, 95% CI= 0.64-1.16, p= 0.34, I2= 0%; and 3 years survival-RRFE= 1.20, 95%CI= 0.92-1.56, p= 0.16, I2= 37.55%). The meta-analysis of studies used nab-paclitaxel showed reduced adverse effect of anemia (ORFE= 1.66, 95% CI= 1.26-2.19; p= <0.001; I2= 0%) and leukopenia (ORFE= 1.37; 95%CI= 1.06-1.75; p= 0.01; I2= 48.63%). However, in case of other adverse effects no significant association was found with nab-paclitaxel (nausea-ORFE=1.15, 95%CI= 0.94-1.41, p= 0.15, I2= 50.12%; neutropenia-ORRE= 0.75, 95%CI= 0.30-1.87, p= 0.54, I2= 94.45%; fatigue-ORRE= 1.11, 95%CI= 0.77-1.62, p= 0.55, I2= 56.02; diarrhea-ORFE= 1.11, 95%CI= 0.77-1.62, p= 0.55; I2= 34.26; pain-ORRE= 1.15, 95%CI= 0.78-1.69, p= 0.45, I2= 52.96%).In conclusion the use of nab-paclitaxel has reduces the side effects of anemia and leukopenia in breast cancer treatment in comparison to paclitaxel but nab-paclitaxel has no effect on the overall survival of the patients.

AbstractDespite the fact that the long-term survival rate of breast cancer patients had been significantly improved owing to the systemic breast cancer therapies, there are still some side effects such as amenorrhea and fertility retention to be resolved, leaving it an important thing to understand the possible side effects on fertility and fertility preservation strategies while undergoing breast cancer treatment, due to the fact that most young patients hope to become pregnant and have children after breast cancer treatment. With anti-müllerian hormone (AMH) being the most sensitive marker for predicting ovarian function in young premenopausal women with breast cancer, this review is aimed to provide the additional guidance for clinical application of AMH by exploring the impacts of AMH on the fertility of young breast cancer patients, the relationship between AMH and metabolism, and the relationship between BRAC gene mutation and fertility protection strategies.

Summary: Our meta-analysis focused on the relationship between homocysteine (Hcy) level and the incidence of aneurysms and looked at the relationship between smoking, hypertension and aneurysms. A systematic literature search of Pubmed, Web of Science, and Embase databases (up to March 31, 2020) resulted in the identification of 19 studies, including 2,629 aneurysm patients and 6,497 healthy participants. Combined analysis of the included studies showed that number of smoking, hypertension and hyperhomocysteinemia (HHcy) in aneurysm patients was higher than that in the control groups, and the total plasma Hcy level in aneurysm patients was also higher. These findings suggest that smoking, hypertension and HHcy may be risk factors for the development and progression of aneurysms. Although the heterogeneity of meta-analysis was significant, it was found that the heterogeneity might come from the difference between race and disease species through subgroup analysis. Large-scale randomized controlled studies of single species and single disease species are needed in the future to supplement the accuracy of the results.

The topic of what interviews measure has received a great deal of attention over the years. One line of research has investigated the relationship between interviews and the construct of cognitive ability. A previous meta-analysis reported an overall corrected correlation of .40 ( Huffcutt, Roth, & McDaniel, 1996 ). A more recent meta-analysis reported a noticeably lower corrected correlation of .27 ( Berry, Sackett, & Landers, 2007 ). After reviewing both meta-analyses, it appears that the two studies posed different research questions. Further, there were a number of coding judgments in Berry et al. that merit review, and there was no moderator analysis for educational versus employment interviews. As a result, we reanalyzed the work by Berry et al. and found a corrected correlation of .42 for employment interviews (.15 higher than Berry et al., a 56% increase). Further, educational interviews were associated with a corrected correlation of .21, supporting their influence as a moderator. We suggest a better estimate of the correlation between employment interviews and cognitive ability is .42, and this takes us “back to the future” in that the better overall estimate of the employment interviews – cognitive ability relationship is roughly .40. This difference has implications for what is being measured by interviews and their incremental validity.

Abstract. In a widely publicized set of studies, participants who were primed to consider unethical events preferred cleansing products more than did those primed with ethical events ( Zhong & Liljenquist, 2006 ). This tendency to respond to moral threat with physical cleansing is known as the Macbeth Effect. Several subsequent efforts, however, did not replicate this relationship. The present manuscript reports the results of a meta-analysis of 15 studies testing this relationship. The weighted mean effect size was small across all studies (g = 0.17, 95% CI [0.04, 0.31]), and nonsignificant across studies conducted in independent laboratories (g = 0.07, 95% CI [−0.04, 0.19]). We conclude that there is little evidence for an overall Macbeth Effect; however, there may be a Macbeth Effect under certain conditions.
