Background: Identifying effective biomarkers plays a critical role on screening; rapid diagnosis; proper managements and therapeutic options, which is helpful in preventing serious complications. The present study aimed to compare the liver laboratory tests between alive and dead hospitalized cases for prediction and proper management of the patients. Methods: This retrospective, cross sectional study consists of all deceased patients admitted in one center in Shiraz, Iran during 19 Feb 2020 to 22 Aug 2021. For further comparison, we selected a 1:2 ratios alive group randomly. Results: Overall, 875 hospitalized cases died due to COVID-19. We selected 1750 alive group randomly. The median age was significantly higher in died group (65.96 vs 51.20). Regarding the laboratory findings during the hospitalization ALT, AST, Bili.D were significantly higher in non-survivors than survivors but Albumin was less in deceased patients. It was revealed elevated levels of Albumin, AST, Bili.T and Bili.D were associated with increasing the risk of in hospital death. Moreover, the predictive effect of ALP and Bili.D had significantly more than others with high sensitivity and specify. Conclusion: We found patients with COVID-19 have reduced serum albumin level, and increase ALT and AST. The current results revealed abnormal liver chemistries is associated with poor outcome, which highlighted the importance of monitoring these patients more carefully and should be given more caution.

Background: Present study aimed to investigate immunohistochemical parameters in post-surgical cases of invasive breast cancer. Methods: In this single center cross-sectional study we investigated ethnicity, familial history, type of cancer, stage of cancer, lymph node positivity, bilateral involvement, metastasis and immunohistochemical parameters (estrogen and progesterone receptor, human epidermal growth factor receptor 2, as well as frequency of triple positive and triple negative patients merely based on immunohistochemical parameters). Results: Frequency of positive familial history was 27.42% (16.31-38.52%). Lymph node involvement was detected in 55.93% (43.26-68.60%) of the cases. Frequency of positive HER2 was 38.60% (25.96-51.23%). There were 17.54% (7.67-27.42%) of triple positive and 7.02% (0.39-13.65%) of triple negative cases. The most common stage at the time of diagnosis was stage 3 with 43.33% (30.79-55.87%) frequency. In Lur/Lak population higher frequency of positive HER2 cases was detected whereas in Mazani population frequency of positive HER2 cases was low (p=0.0291). Conclusions: These results could contribute to understanding of breast cancer patterns among different ethnicities. In order to draw clear conclusion future investigations have to be done in several health centers, for longer time periods and with larger number of patients.

Objective Pregnancy-associated plasma protein-A2 (PAPP-A2) is a metalloproteinase that cleaves IGFBP-3 and IGFBP-5. Human mutations in PAPPA2 result in short stature with a low percentage of free IGF-I. Little is known about PAPP-A2 levels and the regulation of free IGF-I throughout childhood. We examined PAPP-A2 and intact IGFBP-3 levels in childhood and explored associations between PAPP-A2, free and total IGF-I, and total and intact IGFBP-3 and their relationship to the percentage of free to total IGF-I and anthropometric factors. Design Cross-sectional study at a single center. Methods PAPP-A2, free IGF-I, and intact IGFBP-3 levels were measured in childhood (3–18 years old) and an evaluation of the relationship between these proteins and anthropometric factors. Results In 838 children, PAPP-A2 consistently decreased throughout childhood. In contrast, free IGF-I increased. A pubertal peak in free IGF-I was present in females but was less evident in males. Intact and total IGFBP-3 increased throughout childhood; however, intact IGFBP-3 had a more marked rise than total IGFBP-3. Percent free IGF-I decreased with no distinct pubertal peak. PAPP-A2 levels positively correlated with the percent free IGF-I (Male, Female; r = 0.18, 0.38; P < 0.001) and negatively with intact IGFBP-3 (Male, Female; r = −0.58, −0.65; P < 0.0001). Conclusions This is the first study to describe serum PAPP-A2 and intact IGFBP-3 in children between 3 and 18 years of age. Our correlative findings suggest that PAPP-A2 is an important regulator of the percent free IGF-I which can be a marker of perturbations in the GH/IGF-I axis.
