Value of follicular fluid vitamin D in predicting the pregnancy rate in an IVF program

Purpose This study investigated whether there is a correlation between levels of 25OH-D in the follicular fluid and the serum of infertile women and the results of IVF and rates of pregnancy. The association between the levels of 25OH-D in the follicular fluid and the vitamin D repletion status was also assessed. Methods Two hundred and twenty-one infertile women participated in an IVF cycle from 2010 to 2011 in a prospective observational study. Serum and follicular fluid were collected for vitamin D analysis. Deficient, insufficient, and sufficient levels of vitamin D were defined as 10, 10–29, and 30–100 ng/ml, respectively. IVF cycle parameters and clinical pregnancy rates were also compared with the vitamin D level. Results The levels of vitamin D deficiency, insufficiency, and sufficiency were 22.6, 70.1, and 7.2 %, respectively. The fertilization rates associated with these three levels of vitamin D were 43.17, 53.37, and 58.77 %, respectively, (P = 0.054), and the implantation rates were 17.33, 15.26, and 18.75 %, respectively, (P = 0.579). No significant correlation was seen between the pregnancy rate and the serum vitamin D level (P = 0.094) or the follicular vitamin D level (P = 0.170). The serum and follicular fluid vitamin D levels showed a significant correlation (P = 0.000). Conclusion Although vitamin D is an important hormone in the human body, no correlation was found between the serum and follicular vitamin D level and the pregnancy rate in the IVF cycle.

Synthesis and characterization of four new unsymmetrical potentially pentadentate Schiff base ligands and related Zn(II) and Cd(II) complexes

Two thioether diamines 2-(2-aminoethylthio)aniline and 2-(3-aminopropylthio)aniline have been prepared employing a new procedure by reaction of 2-aminothiophenol and N-(2-bromoethyl)phthalimide or N-(3-bromopropyl)phthalimide, respectively. Then two new potentially pentadentate (N2O2S) Schiff base ligands derived from direct condensation between two maintained diamines and 2-hydroxybenzaldehyde or 5-bromo-2-hydroxy benzaldehyde were synthesized. Also, Zn(II) and Cd(II) complexes of Schiff base ligands have been prepared. These compounds have been characterized by physico-chemical and spectroscopic methods

Lipoma of the nasal septum: A case report

Even routine diagnoses, such as septal deviation, which most people do not think need imaging, require careful examination because rare diagnoses such as lipoma may occur in the nose. Careful examination and imaging lead to the best treatment. © 2020 The Authors. Clinical Case Reports published by John Wiley & Sons Lt

Maternal and neonatal outcomes among pregnant women with different polycystic ovary syndrome phenotypes: A cross-sectional study

Background: Pregnancy is a process associated with various metabolic and hormonal changes, and polycystic ovary syndrome (PCOS) can affect this process. Objective: This study aimed to evaluate and compare the maternal and neonatal outcomes among pregnant women with different polycystic ovary syndrome phenotypes. Materials and Methods: In this cross-sectional study, 200 pregnant women with PCOS according to the 2003 ESHRE/ASRM criteria were categorized into four phenotype groups (A-D). The maternal outcomes include gestational diabetes mellitus, pregnancy-induced hypertension, premature rupture of membranes, preterm labor, small-for-gestational age birth, intrauterine growth restriction, intrauterine mortality, preeclampsia, abortion, amniotic fluid disorders, delivery method, and cause of cesarean section were studied between groups. Additionally, neonatal outcomes such as neonatal weight, neonatal recovery, 5-min Apgar score, neonatal icter, the need for NICU admission, the cause of hospitalization, and infant mortality rate were investigated and compared among the groups. Results: According to the results, phenotype D (37%) was the most common phenotype among the participants. The risk of gestational diabetes was more common in phenotype A than in the other phenotypes, whereas pregnancy-induced hypertension was most common in phenotype B. No significant differences were observed in the neonatal complications among the PCOS phenotypes. Conclusion: Considering the higher risk of gestational diabetes mellitus and pregnancy-induced hypertension in PCOS phenotypes A and B, women with these phenotypes need more precise prenatal care.

Outcome of cryopreserved-thawed embryo transfer in the GnRH agonist versus antagonist protocol

Abstract Background: GnRH agonist and antagonist were developed to control the premature release of LH surge. There is some difference between two protocols. Objective: We compared the outcome of frozen-thawed embryo transfer in infertile women who used GnRH agonist or antagonist protocol for previous COH cycle and evaluation of any adverse effect of GnRH antagonist on oocyte and embryo. Materials and Methods: The study group included all infertile women who referred to Yazd Research and Clinical Center for Infertility. Overall 20-35 years old women who were candidate for frozen-thawed embryo transfer with regard to inclusion and exclusion criteria were participated in the study. The patients based on previous control ovarian stimulation (COH) protocol divided in to two groups: GnRH agonist long protocol (n=165) and GnRH antagonist multiple dose protocol (n=165). Frozen-thawed embryos were transferred after endometrial preparation in both groups. Main outcome measures were: implantation, chemical and clinical pregnancy rate. Results: The implantation and clinical pregnancy rate following cryopreserved embryo transfer in GnRH agonist group and antagonist group were 16.3% vs. 15.7% (p=0.806) and 38.1% (63/165) vs. 36.9% (61/165) (p=0.915) and chemical pregnancy rate was 44.8% (74/165) vs. 43.6% (72/165) (p=0.915) respectively. Conclusion: There was no statistically difference between two groups in terms of implantation and pregnancy rate. Although pregnancy rate in fresh embryo transfer in antagonist cycles was lower than agonist groups, Therefore decrease in these parameters might be due to detrimental effect of GnRH antagonist on the endometrium, not embryo or oocyte

Chronic or Recurrent Invasive Fungal Sinusitis after COVID-19 Infection

Background: During the COVID-19 epidemic, we have witnessed numerous manifestations and complications after contracting this disease. One of these complications in patients with COVID-19 is the increased risk of invasive fungal infections due to the suppression of the immune system caused by the disease or due to the use of suppressive drugs such as corticosteroids. Case presentation: Here we report three cases of invasive fungal sinusitis after contracting COVID-19 with recurrence after primary treatment and the measures taken for these patients. Discussion: Invasive fungal sinusitis with involvement of orbit or brain is a known complication in COVID-19 patients especially in diabetics. Recurrence of manifestations of fungal infection after primary treatment and hospital discharge may be related to uncontrolled underlying disease and residual fungal infection especially in necrotic soft tissue or bone. Conclusion: Early diagnosis and management with antifungal drugs and surgical debridement and also close follow up after discharge from hospital is essential for treatment and achieving higher survival in patients with invasive fungal sinusitis

Human leukocyte antigen class I (A, B) and class II (DRB1) allele and haplotype frequencies in Iranian patients with Buerger's disease

Objective: The aim of this study was to investigate the human leukocyte antigen (HLA) class I (HLA-A and HLA-B) and II (HLA-DRB1) allele and haplotype frequencies in a group of Iranian patients with Buerger's disease (BD) in comparison with a normal healthy control group. Methods: A total of 70 unrelated male patients and 100 healthy controls from Sina Hospital, Tehran, Iran, belonging to the same ethnic background, were enrolled in this case-control study. HLA-A, B, and DRB1 typing were performed by polymerase chain reaction with sequence-specific primers (PCR-SSP). Results: The results of this case-control study showed that the frequency of the HLA-A*03:01 (odds ratio (OR) = 2.88, P value (Pv) =.002), HLA-A*29:01 (OR = 15.31, Pv <.001), HLA-DRB1*04:02 (OR = 3.41, Pv <.001), and HLA-DRB1*16:01 (OR = 8.16, Pv <.001) was significantly higher in BD patients compared with healthy controls, whereas the frequency of the HLA-DRB1*01:01 (OR = 0.03, Pv <.001) was significantly lower in BD patients. The most frequent extended haplotypes in our patients were HLA-A*02:01-B*55:01-DRB1*04:03. Conclusion: This study is the first study evaluating an association between the HLA pattern and BD in the patients with BD from North West and North Iran. © 2020 The Authors.

EVALUATION OF HARVESTING TIME EFFECTS AND CULTIVARS OF KENAF ON PAPERMAKING

This study investigates the effect of six cultivars named Cubano, Niger, Cubano 2032, 9277, 7551 and, 7566, of kenaf and three harvesting time stages on pulp and handsheet paper properties of kenaf, which were accomplished in north of Iran. Six cultivars of an Iranian kenaf (Hibiscus Cannabinus L.), were planted on 19 May 2007, and harvested at 85, 105, and 135 days after planting. It was understood that with the increase of plant age, the fiber yield increased. Maximum yield at each of three harvesting time stages was related to Niger. Consequently, if a high fiber yield is sought, Niger can be recommended. But if a paper with high strength properties is to be requested, Cubano 2032 is strongly associated with significant burst, tear, breaking length, and fold endurance even though its yield shows a bit lesser than Niger at short harvesting times. Moreover, at second harvesting time stage, maximum strength properties of handsheets such as burst, tear, breaking length, and fold endurance were related to Cubano, though the fiber yield of this cultivar was a bit lesser than Niger, but it was still more than Cubano 2032. In comparison between harvesting time stages, it is clearly understood from the composition of harvesting time of third stage to first and second stage, a minor positive effect on the handsheets properties with increasing harvesting times has appeared
