    BACKGROUND AND OBJECTIVE: Ectopic pregnancy is a common complication and one of the causes of pregnancy-related deaths. Considering the increased prevalence of ectopic pregnancy in recent years and the increased risk factors such as assisted reproductive treatment, the present study was conducted to investigate the risk factors for ectopic pregnancy in Babol, northern Iran. METHODS: This case-control study was performed on pregnant women who were admitted with suspicion for ectopic pregnancy or acute abdomen within a 6-year period. Patients diagnosed with ectopic pregnancy were selected in the case group and the control group was selected from among the pregnant women's medical record during the same years. Patients were examined in terms of age, parity, history of abortion, type of contraception, history of ectopic pregnancy, history of pelvic infections, history of cesarean section, infertility treatment, history of smoking, marriages within the family, medical history and underlying disease. FINDINGS: In this study, 201 patients were examined in each group. The mean age for the case group was 29.75±5.6 and for the control group was 28.62±6.4 years. Among the risk factors, assisted reproductive treatment (OR=10.24, p≤0.001), abdominal and pelvic surgery (OR=2.35, p=0.002), infertility (p=6.76, p<0.001), contraceptive pills (OR=0.61, p<0.001) and nulliparity (OR = 1.61, p=0.019) were associated with increased risk of ectopic pregnancy. CONCLUSION: According to the results of this study, the most important risk factors for ectopic pregnancy are the use of hormonal pills to prevent pregnancy and nulliparity, respectively

    Inflammatory myofibroblastic tumor (IMT) is assumed as a rare benign tumor that can appear in various organs. Since Umiker et al. introduced inflammatory pseudotumors for the first time in 1954, it was found that occurrence in the head of pancreas is very rare (Baião et al., 2019) 1. Differentiating non-neoplastic lesions of pancreas from adenocarcinoma remains a challenge despite advances in diagnostic modalities whereas cystic and solid lesions and some normal anatomic variants can mimic malignancy (Okun and Lewin, 2016 Jan 1) 2. Histologic patterns of IMT can be identified as fibroblastic and myofibroblastic proliferation with inflammatory infiltrate. They are more common in Women and peak of occurrence is between 2 and 16 years of age (Mirshemirani et al., 2011) 3. In head of pancreas the disease can present with obstructive jaundice and the key for diagnosis is having a tissue specimen by means of needle biopsy. Though in all reported cases surgery is suggested as the lone treatment option, its natural history is obscure still and there can be a challenge in its treatment and also the extent of surgery. Here a new case of IMT of head of pancreas is reported. © 202

    A cell-surface heparan proteoglycan called Syndecan-1 (SDC-1) has multiple roles in healthy and pathogenic conditions, including respiratory viral infection. In this study, we explore the dynamic alternation in the levels of SDC-1 in cases with COVID-19. A total of 120 cases definitely diagnosed with COVID-19 were admitted to the Firoozgar Hospital, Tehran, Iran, from December 1, 2020, to January 29, 2021, and included in our study. Also, 58 healthy subjects (HS) were chosen as the control group. Patients were classified into two groups: 1) ICU patients and (63 cases) 2) non-ICU patients (57 cases). The dynamic changes of serum SCD-1, CRP, IL-6, IL-10, IL-18, and Vit D levels a well as the disease activity were investigated in three-time points (T1-T3). Our results indicated that the COVID-19 patients had significantly increased SCD-1, CRP, IL-6, IL-10, and IL-18 levels than in HS, while the Vit D levels in COVID-19 patients were significantly lower than HS. Further analysis demonstrated that the SCD-1, CRP, IL-6, IL-10, and IL-18 levels in ICU patients were significantly higher than in non-ICU patients. Tracking dynamic changes in the above markers indicated that on the day of admission, the SCD-1, CRP, IL-6, IL-10, and IL-18 levels were gradually increased on day 5 (T2) and then gradually decreased on day 10 (T3). ROC curve analysis suggests that markers mentioned above, SDC-1, IL-6, and IL-18 are valuable indicators in evaluating the activity of COVID-19. All in all, it seems that the serum SDC-1 levels alone or combined with other markers might be a good candidate for disease activity monitoring. © 2021 Elsevier B.V

    The authors investigated the prevalence of low bone mass in patients from Tehran, Iran, with β-thalassemia major (n = 203), aged 10-20 years, and the potential risk factors for osteoporosis in this patient population. Prevalence of osteoporosis was 50.7 in lumbar spine, 10.8 in femur, and 7.9 in both regions with no significant difference between the two genders. The following factors were associated with low BMD: height for age and weight for age below 3rd percentile, delayed puberty or hypogonadism, age when Desferal (for iron chelation) was started, duration of Desferal therapy, and serum zinc. Low serum copper and 25(OH)D were not associated with low BMD. Copyright © Informa Healthcare USA, Inc

    BACKGROUND: The combination of transfusion and chelation therapy has dramatically extended the life expectancy of thalassemic patients. The main objective of this study is to determine the prevalence of prominent thalassemia complications. METHODS: Two hundred twenty patients entered the study. Physicians collected demographic and anthropometric data and the history of therapies as well as menstrual histories. Patients have been examined to determine their pubertal status. Serum levels of 25(OH) D, calcium, phosphate, iPTH were measured. Thyroid function was assessed by T3, T4 and TSH. Zinc and copper in serum were determined by flame atomic absorption spectrophotometry. Bone mineral density (BMD) measurements at lumbar and femoral regions have been done using dual x-ray absorptiometry. The dietary calcium, zinc and copper intakes were estimated by food-frequency questionnaires. RESULTS: Short stature was seen in 39.3% of our patients. Hypogonadism was seen in 22.9% of boys and 12.2% of girls. Hypoparathyroidism and primary hypothyroidism was present in 7.6% and 7.7% of the patients. About 13 % of patients had more than one endocrine complication with mean serum ferritin of 1678 ± 955 micrograms/lit. Prevalence of lumbar osteoporosis and osteopenia were 50.7% and 39.4%. Femoral osteoporosis and osteopenia were present in 10.8% and 36.9% of the patients. Lumbar BMD abnormalities were associated with duration of chelation therapy. Low serum zinc and copper was observed in 79.6% and 68% of the study population respectively. Serum zinc showed significant association with lumbar but not femoral BMD. In 37.2% of patients serum levels of 25(OH) D below 23 nmol/l were detected. CONCLUSION: High prevalence of complications among our thalassemics signifies the importance of more detailed studies along with therapeutic interventions

    Multifactorial anticancer effects of digalloyl-resveratrol encompass apoptosis, cell-cycle arrest, and inhibition of lymphendothelial gap formation in vitro

    BACKGROUND: Digalloyl-resveratrol (di-GA) is a synthetic compound aimed to combine the biological effects of the plant polyhydroxy phenols gallic acid and resveratrol, which are both radical scavengers and cyclooxygenase inhibitors exhibiting anticancer activity. Their broad spectrum of activities may probably be due to adjacent free hydroxyl groups. METHODS: Protein activation and expression were analysed by western blotting, deoxyribonucleoside triphosphate levels by HPLC, ribonucleotide reductase activity by 14 C-cytidine incorporation into nascent DNA and cell-cycle distribution by FACS. Apoptosis was measured by Hoechst 33258/propidium iodide double staining of nuclear chromatin and the formation of gaps into the lymphendothelial barrier in a three-dimensional co-culture model consisting of MCF-7 tumour cell spheroids and human lymphendothelial monolayers. RESULTS: In HL-60 leukaemia cells, di-GA activated caspase 3 and dose-dependently induced apoptosis. It further inhibited cell-cycle progression in the G1 phase by four different mechanisms: rapid downregulation of cyclin D1, induction of Chk2 with simultaneous downregulation of Cdc25A, induction of the Cdk-inhibitor p21(Cip/Waf) and inhibition of ribonucleotide reductase activity resulting in reduced dCTP and dTTP levels. Furthermore, di-GA inhibited the generation of lymphendothelial gaps by cancer cell spheroid-secreted lipoxygenase metabolites. Lymphendothelial gaps, adjacent to tumour bulks, can be considered as gates facilitating metastatic spread. CONCLUSION: These data show that di-GA exhibits three distinct anticancer activities: induction of apoptosis, cell-cycle arrest and disruption of cancer cell-induced lymphendothelial disintegration.
