Causes of Infant Mortality in Babol, Northern Iran

Background and Objective: Infant mortality is an important health indicator. In order to reduce infant mortality, its causes should be considered in each region so that steps can be taken to improve the quality of health care and treatment. Therefore, this study was conducted in order to determine the causes of infant mortality in Babol, northern Iran. Methods: This cross-sectional study was conducted on all infants who died in public and private hospitals of Babol. The cause of infant death was extracted and analyzed based on the International Classification of Diseases 10th Revision (ICD-10) and also based on laboratory, clinical and paraclinical evidence recorded in the files. Findings: Out of a total of 16,005 live births in Babol, 123 infants (7.6%) died, of which 53 (43.1%) died in the first 24 hours of life. The mean gestational age of the deceased cases was 31.4±5.5 weeks, the mean birth weight was 1705.4±1045.3 grams, and their mean life span was 5.4±6.6 days. The most common causes of infant mortality were prematurity (30%), congenital anomalies (25.3%), sepsis (17.1%) and respiratory distress syndrome (13%). Conclusion: The results of the study showed that the most common causes of infant mortality are prematurity and congenital anomalies

Long-term recurrence of endometriosis in women with subfertility caused by endometriosis: A comparison of the efficacy of surgery and assisted reproductive technology as fertilization treatment approaches

Background: The evolution of fertility treatment methods such as laparoscopic surgery and assisted reproductive technology (ART) leads to an increased chance for conception in women with endometriosis. However, it is still not clear which treatment is more likely to result in endometriosis recurrence. Objectives: The current study aimed at assessing the recurrence rate of endometriosis and its main determinants following fertility treatment with surgery or ART. Methods: The current historical cohort study was conducted on 51 consecutive women with endometriosis undergoing fertilization procedures, including laparoscopic surgery (n = 42) and ART (n = 9) in Tehran from 2006 to 2016. All patients with complete hospital records were enrolled in the study. The patients in the two groups were followed up for five years for endometriosis recurrence. Results: Within the follow-up time, the rate of endometriosis recurrence in patients of the surgery and ART groups was 28.6 and 44.4, respectively, indicating no significant difference between the groups (P = 0.436). In this regard, the 1-, 2-, and 3-year recurrencefree survival rate in the ART group was 87.5, 50.0, and 50.0, and in the surgery group was 96.9, 90.6, and 70.5, respectively. Using the Cox proportional hazard modeling adjusted for baseline variables, the method of fertilization (ART or surgery) could not affect the rate of long-term recurrence of endometriosis (odds ratio = 1.428, 95 confidence interval: 0.177-9.900, P = 0.784). Conclusions: The method of fertilization treatment-e g, surgery, and ART-may not affect the rate of endometriosis recurrence in women with subfertility caused by endometriosis. © 2020, Author(s)

Current approaches for combination therapy of cancer: The role of immunogenic cell death

Cell death resistance is a key feature of tumor cells. One of the main anticancer therapies is increasing the susceptibility of cells to death. Cancer cells have developed a capability of tumor immune escape. Hence, restoring the immunogenicity of cancer cells can be suggested as an effective approach against cancer. Accumulating evidence proposes that several anticancer agents provoke the release of danger-associated molecular patterns (DAMPs) that are determinants of immunogenicity and stimulate immunogenic cell death (ICD). It has been suggested that ICD inducers are two different types according to their various activities. Here, we review the well-characterized DAMPs and focus on the different types of ICD inducers and recent combination therapies that can augment the immunogenicity of cancer cells

A systematic review and meta-analysis of outcomes after elective surgery for ulcerative colitis.

AIM: Approximately 20%-30% of patients with ulcerative colitis (UC) will undergo surgery during their disease course, the vast majority being elective due to chronic refractory disease. The risks of elective surgery are reported variably. The aim of this systematic review and meta-analysis is to summarize the outcomes after elective surgery for UC. METHODS: A systematic review was conducted that analysed studies reporting outcomes for elective surgery in the modern era (>2002). It was prospectively registered on the PROSPERO database (ref: CRD42018115513). Searches were performed of Embase and MEDLINE on 15 January 2019. Outcomes were split by operation performed. Primary outcome was quality of life; secondary outcomes were early, late and functional outcomes after surgery. Outcomes reported in five or more studies underwent a meta-analysis of incidence using random effects. Heterogeneity is reported with I2 , and publication bias was assessed using Doi plots and the Luis Furuya-Kanamori index. RESULTS: A total of 34 studies were included (11 774 patients). Quality of life was reported in 12 studies, with variable and contrasting results. Thirteen outcomes (eight early surgical complications, five functional outcomes) were included in the formal meta-analysis, all of which were outcomes for ileal pouch-anal anastomosis (IPAA). A further 71 outcomes were reported (50 IPAA, 21 end ileostomy). Only 14 of 84 outcomes received formal definitions, with high inter-study variation of definitions. CONCLUSION: Outcomes after elective surgery for UC are variably defined. This systematic review and meta-analysis highlights the range of reported incidences and provides practical information that facilitates shared decision making in clinical practice

Comparison of DNA polymorphism of bovine pituitary-specific transcription Factor and Leptin Gene Between Iranian Bos indicus and Bos taurus Cattle Using PCR-RFLP.

Variations at DNA level contribute to the genetic characterization of livestock populations and this may help to identify possible hybridization events as well as past evolutionary trends. The leptin and Pit-1 are attractive candidate genes for production and reproduction traits in cattle. A total of 247 animals from four breeds from two species of Iranian cattle populations in include Bos taurus (Sarabi, Golpayegani) and Bos indicus (Sistani, Taleshi) were genotyped for the Pit-1 Hinfl and leptin Sau3AI polymorphisms by the Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP). The genotype and gene frequencies for each group were determined and shown to be quite variable among the breeds. The allele B for the leptin gene and allele A for the Pit-1 gene were investigated high frequency in Bos indicus. Candidate gene approach may be a useful method to measure of genetic distance for cross breeding program between taurin and indicine cattle

Cytotoxic t-lymphocyte antigen-4 in colorectal cancer: Another therapeutic side of capecitabine

Cytotoxic T lymphocyte antigen-4 (CTLA-4) is an inhibitory immune checkpoint that can be expressed in tumor-infiltrating lymphocytes and colorectal cancer (CRC) cells. This immune checkpoint can attenuate anti-tumoral immune responses and facilitate tumor growth and metastasis. Although capecitabine is an effective chemotherapeutic agent for treating CRC, its effect on the tumoral CTLA-4 expression remains unclear. In the current research, we applied the GSE110224 and GSE25070 datasets to characterize CTLA-4 expression in CRC patients. Then, we analyzed CTLA-4 expression in CRC samples, HT-29, HCT-166, and SW480 cell lines using real-time PCR. Our bioinformatic results have highlighted the overexpression of CTLA-4 in the CRC tissues compared to the adjacent non-tumoral tissues. Our in vitro studies have indicated that SW480 cells can sub-stantially overexpress CTLA-4 compared to HT-29 and HCT 116 cells. In addition, capecitabine can remarkably downregulate the expression of CTLA-4 in SW480 cells. Collectively, capecitabine can inhibit the expression of CTLA-4 in CRC cells and might bridge the immunotherapy approaches with chemotherapy
