Abstract

Background: A balanced reciprocal translocation is a structural abnormality, which at least consist of breakage of two non-homologous chromosomes along with pieces exchange and form quadrivalant structure that can produce unbalanced chromosomes during meiosis I and result in a fetus abortion. The aim of the present study is to offer using preimplantation genetic diagnosis (PGD) 24sure array, which delivers aneuploidy screening of 24 chromosomes, within a few hours to increase fertility and bearing a child without chromosomal abnormality of this couple. This technique could replace embryo donation for child bearing of this couple. Case presentation: A young couple with recurrent pregnancy loss in 6th and 7th week of pregnancy without family history of recurrent miscarriage and any clinical signs had conferred. All laboratory tests including hormonal, infections, semen and hysterosalpingography were normal except karyotype that showed balanced reciprocal translocation between chromosomes 5 and 18 in male. Chromosomal study of male parents showed normal karyotype. Conclusion: A balanced reciprocal translocation carrier is phenotypically normal, but during meiosis І, carrier chromosomes cant pair normally and form quadrivalant instead of bivalant that depend on type of their segregation (alternate, adjacent 1, adjacent 2,3:1,4:0), produce gametes that are chromosomally unbalanced which can result in early fetus abortion. Considering the number of abnormal gametes, the most effective way to help couples with this problem seems to be PGD 24sure, since it can identify reciprocal and Robertsonian translocation and allows concurrent screening of all chromosomes for aneuploidy. Another technique that can be compared with PGD 24sure is fluorescence in situ hybridization (FISH), but it has several technical limitations such as it is expensive and complexity, in addition it has only few probes (for chromosomes 21, 13, 18, X, Y) so sometimes necessary to create patient specific protocols.

Abstract

Background: The aim of this study was to assess the role of consolidative intraperito-neal chemotherapy with carboplatin in decreasing relapse and increasing survival in advanced epithelial ovarian cancers, as well as evaluation of its toxicity. Methods: In this clinical trial 30 patients with epithelial ovarian cancer in stages II-IV who had complete surgery (optimal debulking surgery) received six standard cycles of intravenous carboplatin and paclitaxel. They were enrolled through non-random se-quential selection. The control patients were similar to case group in stage (II-IV) and pathology (epithelial ovarian cancer). The control group was evaluated retrospectively through hospital files. This clinical trial performed in Gynecology Oncology department in Tehran Valiasr University Hospital, during 2005-2010. They including 18 cases as the intervention group receiving intraperitoneal chemotherapy and 12 patients as the control group with only retrospective follow-up. The cases received 3 cycles of 400 mg/m2 intraperitoneal carboplatin every 21 days following intravenous chemotherapy. Relapse of disease was diagnosed as increasing or even doubling CA125 serum titer during one month, or any CA125 above 100 IU, or an abdominal or pelvic mass in ul-trasound or physical exam. Mean survival of two and five years, progression-free inter-val (PFI), overall survival (OS), relapse, demographic parameters, drug toxicities, path-ologic types of cancers in two groups were coded and compared using SPSS 14. Any P<0.05 was considered as a significant difference. Results: The mean ages of cases and controls were 52.4±8.6 and 55.1±11.5 years. The mean duration of relapse-free survival was 13±8.6 months for the cases and 9.5±4.3 months for the control patients (not statistically different, P>0.05). The mean overall survival for cases and controls were 39±16.5 and 30.8±16.2 months, respectively (no significant difference, P>0.05). The frequency of drug toxicities in the cases was 5.6%, and consisted of mild-to-moderate abdominal pain, nausea and vomiting. Conclusion: It seems that consolidation therapy with intraperitoneal carboplatin may not increase overall survival, reduce relapse rate or decrease mortality, though it does not induce considerable side effects. Since the mean survival in the intervention group was nine months more than controls, this difference may be clinically significant.

Abstract

Background: The use of Methotrexate (MTX) is a good and common practice for the treatment of women who were diagnosed early with ectopic pregnancy (EP). The aim of this study is to determine the predictors of treatment failure with a single dose of MTX injection. Methods: In this quasi-experimental research, we studied 70 women with ectopic preg-nancies who were treated with MTX, according to a single dose protocol from 2010 to 2013. EP was diagnosed whenever an intrauterine gestational sac was not identified by transvaginal ultrasonography (TVUS), accompanied by an abnormal rise or plateau in human chorionic gonadotropin (beta-hCG) concentration. Briefly, women with ectopic pregnancies were considered candidates for MTX treatment if they were hemodynami-cally stable did not desire surgical therapy, agreed to weekly follow-up and did not have hepatic, hematologic, or renal disease. A Patient was considered a treatment suc-cess (group 1) if her beta-hCG levels decreased ≤10 m IU/ml after the first dose of MTX. Treatment failure (group 2) was defined as the need for a second or a third dose of MTX or surgery. The following risk factors were compared between the two groups: serum beta-hCG on the days 1 and 4, a ≥ 15% decrease in serum beta-hCG between the days 1-4 of the treatment, age, parity, gravidity, the size of the ectopic mass and the endometrial thickness. Results: The success rate of MTX treatment was 77.1%. There were no significant dif-ferences between the two groups in regard to the age, parity, gravidity, the size of ec-topic mass and the endometrial thickness in vaginal sonography, but the mean serum beta-hCG concentration on days 1 and 4 was lower in the success group than the failure group. We also observed a ≥ 15% decrease in serum beta-hCG in 80.9% of the women from the success group and in 38.5% of the cases whose treatment had failed. The presence of fetal heart activity was seen in only one patient and this patient’s treatment failed. Two patients had previous history of ectopic pregnancy and the treatment of both ended in failure. Conclusion: Among women with ectopic pregnancies who were candidates for MTX treatment, a high serum beta-hCG concentration on the days 1-4 and also a ≤ 15% fall in serum beta-hCG between the days 1-4 treatment, are the most important factors associated with the failure of the treatment with a single dose MTX protocol. It is better to use these factors for making decisions about the initiation of the treatment or the continuation of it.

Abstract

Background: The incidence of Patent Ductus Arteriosus (PDA) in premature infants whose birth weight is less than 1500 grams is approximately 30-60%, most of them need medical or surgical interventions. The purpose of this study is to determine the efficacy of prophylactic treatment with oral paracetamol (Acetaminophen- Hakim® Oral Drops 100 mg/ml, Hakim Pharmaceutical Co., Tehran, Iran) for PDA in preterm infants. Methods: A randomized clinical trial conducted from March 2012 to March 2013. Thirty-two preterm newborns whose gestational age was under 32 weeks and birth weight was 1500 grams or less, admitted in neonatal intensive care unit (NICU) of Vali-Asr Hospital, Tehran were studied prospectively. They were randomly assigned in two groups. The prophylaxis group received oral paracetamol for a period of two days starting during first 24 hours of life. No placebo was given to the control group. Echocardiography was performed 24-36 hours after the last given dose in prophylaxis group and on the 4th and 5th day in control group. A p-value less than 0.05 are considered significant. Results: There were 16 newborns in each group (20 boys and 12 girls). In 12 newborns of prophylaxis group the ductus arteriosus was closed although in control group in 8 newborns the duct was closed. No significant difference was observed in sex, gestational age, birth weight, mode of delivery, multifetal gestation and birth order between two groups. The rate of ductal closure was 75% and 50% in prophylaxis group and control group respectively (P=0.27). Conclusion: Our study demonstrated that prophylactic paracetamol is ineffective in PDA closure, although the rate of ductal closure between two groups seems remarkable. Paracetamol as a new strategy for PDA closure because of cost effectiveness and harmlessness may be used in future. However, we presume larger sample size studies are needed to show the efficacy of paracetamol, side effects, and complications in PDA prophylaxis treatment.

Abstract

Background: Environmental signals have an essential role in the maturation of neural circuits during critical period of brain development. It has been shown that, change in visual signals during critical period of brain development changes structure and function of glutamate receptors in the visual cortex. After processing in visual cortex, part of visual signals goes to the hippocampus and makes memories. The aim of this study was evaluating effects of visual deprivation during critical period of brain development on AMPA receptor subunits expression in rats’ hippocampus. Methods: This experimental study was done in Physiology Research Center, Kashan University of Medical Sciences at winter 2014 on male Wistar rats. Animals were divided to 2 groups (n= 36 for each) were kept in standard 12 hours light/12 hours dark condition (light reared, LR) or in complete darkness (dark reared, DR) from birth to the end of the experiments. Using reverse transcription polymerase chain reaction (RT-PCR) and Western blotting techniques respectively, expression of mRNA and protein of GluR1 and GluR2 subunits was evaluated in rats’ hippocampus at ages 2, 4 and 6 weeks in both groups. After quantification of the expressions, the data were compared by two way analysis of variance. Results: The relative expression of GluR1 subunit decreased about 24% (P=0.004) in the hippocampus of 6 WLR rats in comparison to 2 WLR ones. The relative expression of the other AMPA receptor subunit, GluR2, also increased about 190% in the hippocampus of the 6WLR animals when compared to the 2 WLR rats (P< 0.0001). Dark rearing increased the relative expression of both subunits of AMPA receptors, GluR1 and GluR2, about 20 percent (P= 0.01) in the hippocampus of 6 WDR rats in comparison to 2 WLR animals. Conclusion: Dark rearing of rats during critical period of brain development changes the relative expression and also arrangement of both AMPA receptor subunits, GluR1 and GluR2 in the hippocampus, age dependently.

Abstract

Background: It is reported that high frequency of chromosomal aberrations in peripheral blood lymphocytes of individuals is a marker of cancer predisposition. The aim of this study was to investigate the in vitro frequency of chromosomal damage in lymphocytes of patients with head and neck cancer against gamma irradiation compared with those in healthy individuals.

Methods: In a case and control study, peripheral blood lymphocytes of 101 patients with head and neck cancer were collected before the onset of radiotherapy. Lymphocytes of 40 healthy individuals were also collected as controls. Head and neck cancer patients and the control group were consecutively recruited between April 2012 and February 2015 from Clinics of Cancer Institute, Imam Khomeini Hospital, Tehran, Iran. Lymphocytes of patients or control group were cultured and exposed to gamma radiation in G2- and G0- phase of the cell cycle. The induced chromosomal aberrations such as chromosome and chromatid breakages, chromosome and chromatid gaps, chromatid exchanges and micronuclei were scored in one-hundred metaphase cells of each individual. The mean of each chromosomal aberration was compared in patient and control groups. Early and late tissue reactions were scored during radiotherapy treatment or thereafter.

Results: There was no significant difference in demographic characterization between the two study groups. The frequency of radiation- induced G2 aberrations in lymphocytes of patients was significantly higher than in those of healthy donors (P= 0.001 for chromosomal breaks). The frequency of radiation-induced micronuclei in G0 assay was also higher in patients than in those in controls (P= 0.05). The results also indicate that there is no correlation between the two assays. No significant correlation was also observed between aberration frequencies in lymphocytes and the degree of both early and late normal tissue reactions.

Conclusion: The results indicate that the in vitro chromosomal radiosensitivity of peripheral blood lymphocytes of patients with head and neck cancer against gamma irradiation was significantly higher than that in healthy individuals.

Abstract

Background: Small molecule Purmorphamin (PMA) is the agonist of smoothened protein in Sonic hedgehog (Shh) signaling pathway. Effect of purmorphamin small molecule on differentiation of mesenchymal cells into bone tissue has been studied previously. Use of Shh causes progression of neural differentiation, and the differentiated cells express specific neural markers. Neurofilament (NF) and acetylcholine esterase (Chat) are specific markers of motor neurons and their expression in differentiated cells indicates their conversion into motor neurons. The aim of this study was to evaluate the ability of PMA to differentiate the human endometrial stem cells (hEnSCs) into motor neurons.

Methods: This analytical study was done in Tehran University of Medical Sciences laboratory on September of 2015. In this study hEnSCs were enzymatically extracted from endometrial tissue. After third passages, the flow cytometry was done for mesenchymal stem cells markers. The mesenchymal stem cells were divided into control and differentiated groups. FBS 10%+DMEM/F12 was added to the culture medium of control group and the differentiating group was treated with differentiating medium containing N2, PMA, DMEM/F12, FBS, B27, IBMX, 2ME, FGF2, RA, BDNF. After 21 days immunocytochemistry (ICC) test was done for the expression of NF and Chat proteins and Real-time PCR analysis for expression of neural markers such as NF, Chat, Nestin and GFAP (as glial marker) at mRNA level.

Results: The flow cytometry analysis showed that hEnSCs were positive for mesenchymal markers CD90, CD105 and CD146 and negative for endothelial marker CD31, and hematopoietic marker CD34. The immunocytochemistry and Real time-PCR results showed that the cells treated with PMA expressed motor neuron markers of NF and Chat.

Conclusion: According to the results of this study, it can be concluded that small molecule PMA has the potency to induce the differentiation of hEnSCs into neural cells, specifically motor neurons by activating Shh signaling pathway.

Abstract

Background: Sepsis or blood stream infection is a clinical lethal syndrome with severe systemic inflammatory response to infection, if not treated quickly, is associated with dangerous consequences and high morbidity and mortality. The traditional and conventional method for identification of sepsis is blood culture method which is so time-consuming and long that it eliminates the possibility of rapid treatment. Although, new molecular methods, due to their high sensitivity, specificity, and speed, lead to the rapid and accurate and exact detection of bacterial sepsis within only a few hours. The aim of this study was diagnosis of bacteremia in patients with suspected sepsis using amplification of 23S rRNA gene by polymerase chain reaction (PCR).
Methods: This cross-sectional study was performed in two clinical and analytical steps at Shahid Beheshti University Hospital in Kashan City, Iran, in twelve months from November 2016 to December 2017. The blood samples of two hundred and fifty-six patients with suspected sepsis admitted to Shahid Beheshti Hospital were studied by PCR method using specific primers of 23S rRNA gene of the bacteria.
Results: The finding of molecular assays using PCR showed that of 256 blood samples that were collected from patients with clinical signs and symptoms of sepsis, 80 (30.2%) diagnosed with bacteremia. Of these patients diagnosed with sepsis, 46 out of 80 (57.5%) were male while 34 out of 80 (42.5%) were female. The most PCR positive results were obtained among patients with diabetes and bedsore as underlying diseases (21.3%). Statistical analysis showed that there was a significant correlation between results of molecular methods by PCR assays and history of antibiotic use. 
Conclusion: Overall, the results of the present study showed that the molecular methods such as polymerase chain reaction using universal 23S rRNA primers is an appropriated test for diagnosis of bacteremia in blood samples of patients with suspected sepsis.

Abstract

Background: Approximately 3% to 5% of obstetric patients will experience postpartum hemorrhage (PPH). Even though the most common reason for postpartum hemorrhage, as the main cause of maternal death, is uterine atony; other complications such as laceration, hematoma, inversion, rupture; retained tissue or invasive placenta; and coagulopathy may result in PPH. The main cause of retained placenta can be traced to the history of manual placenta removal, violent and numerous curettages, uterus anatomical abnormalities, placenta accreta or placenta previa, and history of cesarean section. Here, we have presented a case of retained placenta and uterus septum.
Case Presentation: The patient, a 36 years old female, multigravid 11 live 3 ,death 1 and abortion 6, with a history of four normal vaginal deliveries, and history of preterm premature rupture of membrane since the 16th week of pregnancy, was admitted to Imam Reza hospital, Mashhad University of Medical Sciences due to labor pain in 29th week of pregnancy. After a vaginal delivery, she was transferred to the operating room due to a retained placenta. During the initial diagnosis, the patient’s cervix was dilated and manual placental removal was not possible. The ultrasound results showed an 80mm heterogeneous tissue in the fundus, extending to the left cornu. There was no sign of accreta. During hysterotomy, the retained placenta was removed from underneath a thick layer of Uterine Septum, using sponge forceps. Five days later, the patient returned with severe pelvic pain and signs of peritonitis. Laparotomy and hysterectomy were performed on account of uterine incision necrosis.
Conclusion: The most crucial step in the treatment of retained placenta lies in the early detection of its cause. The treatment includes manual or Surgical removed of placenta which can result in bleeding, infection, and a lengthy recovery.

Abstract

Background: Acute compartment syndrome is considered a debilitating complication of limb trauma. Early detection of this compartment syndrome helps us in the early initiation of treatment which will result in preventing its subsequent complications reported in these cases.
Methods: This research was an analytical cross-sectional study. Patients with direct trauma to extremities, who were referred to the emergency department of Valiasr and Amir Al-Momenin hospitals were studied from October 2018 to April 2019 in Arak, Iran. Patients were selected if they met all of the inclusion criteria and none of the exclusion criteria. Vital signs were measured and recorded for each patient. Also, the results of physical examination, intra-compartmental pressure measurement by a wick catheter and the level of the creatine phosphokinase were recorded. All data analyses were performed with the use of SPSS v21 software.
Results: A total number of 70 subjects were included in this study, comprising 65 males (93.1%) and 5 females (6.9%). The results showed that there is a significant relationship between intra-compartment pressure and the level of creatine phosphokinase enzyme. The higher the intracompartmental pressure, the higher the creatine phosphokinase level. Statistically significant associations were observed between intracompartmental pressure and pallor, edema, lack of limb pulse, and diastolic blood pressure. No significant relationship was found between intracompartmental pressure and limb pain, numbness, inability to move the injured limbs, and systolic blood pressure. In addition, our findings indicated that creatine phosphokinase is significantly associated with edema and lack of limb pulse. No significant relationship was found between creatine phosphokinase with pain, pallor, numbness, inability to move limbs, and systolic and diastolic blood pressure.
Conclusion: The study findings suggest that measurement of intracompartmental pressure could be considered as an effective alternative approach to creatine phosphokinase levels to diagnose compartment syndrome. So, this will prevent irreparable damage to the extremities and is of great importance.

Abstract

Background: Mycoplasma pneumoniae is one of the causes of upper and lower respiratory tract infections especially in children, and antibiotics affecting the cell wall do not affect this type of infection. This study aimed to evaluate the prevalence of Mycoplasma pneumoniae and macrolide resistance in children with community-acquired pneumonia in Kerman city.
Methods: This cross-sectional study was conducted in a selected teaching hospital in Kerman city from July 2018 to July 2019. Fifty-one children hospitalized in the pediatric ward were diagnosed with bacterial pneumonia acquired from the community. These children were included in the study by census method. The data collection tool was a standard checklist. The checklist was completed by parents. Pharynx and nasal swab samples were taken from all patients. PCR was used to identify mycoplasma.
Results: The highest number of patients with bacterial pneumonia acquired from the community were male (52.9%). The average age of these cases was 5.52±3.93 years and the average weight of these patients was 17.23±10.55 kg. Lung involvement was one-sided in more than half of the patients. The most of lung involvements were lobar (31.4%). More than half of the patients didn’t have any associated involvement (52.9%). The most common type of associated involvement was peribronchial thickening (29.4%). The most commonly used antibiotic was Ceftriaxone (76.5%). The prevalence of Mycoplasma pneumoniae infection in children with pneumonia was 2%. These children had an rRNA gene at position 2063 that had high levels of macrolide resistance.
Conclusion: The results of this study showed very low rates of Mycoplasma pneumoniae infection in children with bacterial pneumonia acquired from the community. Therefore, it can be concluded that in addition to Mycoplasma pneumoniae, other viral and bacterial agents are also involved in respiratory infections that need to be identified and addressed.

Abstract

Background: mechanical bowel preparation (MBP) is a common practice before laparoscopic gynecologic surgeries but the role and efficacy of preparation have been questioned. this study assesses visualization and bowel handling in a group of patients who receive MBP and the control group and thereafter; compares the results.
Methods: We designed and conducted this randomized, single-blinded and controlled trial on patients who underwent advanced gynecologic laparoscopic surgeries. This clinical trial was carried out between July 2020 and January 2021. The patients were enrolled from l the laparoscopic office. 120 women aged 18-65 years undergoing level 2 and 3 benign gynecologic laparoscopic surgeries were randomized to bowel preparation with a normal saline enema (n=60) or non-bowel preparation (n=60) groups. Our patients underwent level 2 and 3 of benign laparoscopic gynecologic surgeries with or without MBP. The visualization and bowel handling were assessed by the primary surgical team and a questionnaire was later obtained. The outcomes included intraoperative surgical view and bowel handling, preoperative and post-operative patient signs and symptoms. The patients were also assessed in respect to discomfort prior and after the surgery, this assessment was obtained using a questionnaire. The gathered data was analyzed using IBM’s SPSS v26 software.
Results: there was no difference in intraoperative visualization and bowel handling between the two groups. We also found no clinical improvements in respect to discomfort and symptoms. MBP even increased the distention rate amongst patients (P-value=0/04). We tried to evaluate whether MBP had any effects on haemorrhage and blood loss during the surgery and to assess this we compared hemoglobin levels before and after the surgery. We compared the subtracted values between the two groups and found no significant difference (T-test=1.135, P=0/259) (see table 4). However, hospitalization duration was about 5 hours longer in the group who received MBP.
Conclusion: MBP with normal saline enema does not improve intraoperative visualization and bowel handling. And it also does not reduce patient complication rates and post-operative symptoms either. MBP also increases hospitalization duration and puts extra pressure on the healthcare system. Therefore, a normal saline enema is not recommended before benign gynecologic laparoscopic surgeries.

Abstract

Background: Vitamin B12 deficiency is one of the most well-known disorders due to long-term use of metformin due to interference with its absorption.
Methods: This double-blind randomized trial was conducted from June to October 2016 at Shahid Beheshti Hospital in Qom on 60 patients in the age group of 30 to 60 years with a history of type 2 diabetes for one to two years and taking metformin in the amount of one to two grams. Patients were divided into two groups of 30 people. The intervention group received metformin with 1 gram of calcium carbonate daily, and the control group received metformin without calcium. Each of the patients in the intervention group was given 200 calcium carbonate tablets. Vitamin B12 levels of the patients in both groups were measured before the start of the intervention, and they were evaluated in terms of neuropathy according to the Michigan questionnaire. Vitamin B12 of patients and neuropathy in two groups were measured before the intervention and after three months.
Results: There was a difference between the two groups in terms of gender, and no significant difference was observed between the mean ages in the two groups. The mean level of vitamin B12 before receiving calcium in group A (intervention) was lower than group B (control) (P=0.036) and after receiving calcium, the level of vitamin B12 in the intervention group increased (P=0.002). In the control group, the level of vitamin B12 decreased (P=0.030). (P=0.006), and in the control group there was no significant difference in the examination of neuropathy (P=0.2).
Conclusion: Oral calcium daily intake increases vitamin B12 levels in patients with type 2 diabetes and calcium may be able to moderate the decrease in serum vitamin B12 levels induced by metformin in patients with type 2 diabetes.

Abstract

Background: Sever Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in some patients leads to cytokine storm and causes hemophagocytic lymphohistiocytosis (HLH) secondary to this viral agent. HLH is a rare and aggressive disease that increases in children, and is caused by changes in the immune system that associated with high mortality. Consideing the current pandemic, early diagnosis and treatment is important. Herein, we report a case of a 14-month-old infant presented with COVID-19 and prolonged fever who was eventually treated with the diagnosis of HLH. The study has been done in Sanandaj in January 2020.
Case Presentation: A 14-month-old female infant with Covid-19, in November 2019 with prolonged fever lasting for 12 days, weakness and lethargy was admitted to Sanandaj Social Security Hospital, in November 2019. The infant did not have any history of illness, drug or allergy and had received vaccination according to the country's protocol. Later she was transferred to Besat Hospital in Sanandaj due to persistent fever and elevated liver enzymes. The patient had severe leukocytosis and hepatosplenomegaly in the second center. During the diagnostic measures for the patient and the rule out of other possible causes through imaging and laboratory investigations and also the evaluation of relevant criteria, HLH was suggested and treated with antibiotics (ceftriaxone, meropenem), IVIg, dexamethasone and pantoprazole. After that the fever decreased, then oral prednisolone was prescribed and a follow-up was recommended. She was discharged in good general condition.
Conclusion: The current Covid-19 pandemic causes infection of children and may lead to occurrence of secondary HLH disease. therefore, assessment of children with liver manifestations and resistant fever should be considered by performing a PCR test to avoid complications and consequences as much as possible by timely treatment. more studies should be done in the field of its various dimensions.

Abstract

Background: The success of labor induction depends on the condition of the cervix at the time of delivery. This study examines the effect of labor induction with an intra-cervical Foley catheter and oxytocin compared to a Foley catheter and misoprostol on cervical preparation and delivery rate in the first 24 hours after induction.
Methods: In a randomized clinical study, pregnant women with a singleton pregnancy and a gestational age of more than 40 weeks, with a Bishop score less than 4 and an intact amniotic sac referred to Umm al-Binin Hospital in Mashhad from 2017 to 2018 were included in the study. They were randomly divided into two groups of Foley catheter and oxytocin (1) or Foley catheter and misoprostol (2). In the first group, immediately after placing the Foley catheter; Oxytocin was started with a dose of 2 milliunits per minute, and every 20 minutes, 2 milliunits were added to reach the maximum dose of 30 milliunits per minute (induction method with a low dose). In the second group, after Foley catheter insertion, sublingual misoprostol was prescribed at a dose of 25 micrograms every 4 hours up to a maximum of 6 doses.
Results: 74 pregnant women were randomly evaluated in two groups of 37 people. There is no statistically significant difference in the demographic variables in the two groups. There was a significant difference in the labor rate in the first 24 hours, and it was higher in the oxytocin group (P=0.009). Bishop's score after 24 hours of induction was not significantly different in the two groups. Reaching the active phase was significantly shorter in the oxytocin group. (P=0.01). The time of catheter removal in both groups and the rate of cesarean section and the occurrence of complications were the same in both groups.
Conclusion: The use of oxytocin with a Foley catheter inside the cervix can accelerate the preparation of the cervix and increase the chance of labor in the first 24 hours, but it does not affect labor complications.

Abstract

Background: Asthma is a chronic inflammatory disease of the airways. Various tests and questionnaires are designed to monitor the severity of asthma and help the therapist and the health system prescribe the best treatment to control it. This study was designed to compare two methods Asthma Control Questionnaires (ACQ) and Asthma Control test-child (ACT-CHILD) in children with asthma.
Methods: This descriptive cross-sectional study was conducted on 92 children with asthma referred to the Taleghani hospital, Gorgan, in 2022-2023. Patients were in a range of age 4-16 years. Asthma control was evaluated and compared by two methods ACT-CHILD and ACQ. ACT-CHILD included one version for 4-11-year patients completed by their parents and another one for 12-16 –year patients completed by the patients. The clinical symptoms, age, gender and the parents' records related to asthma were completed during the clinical interview. Data was analyzed using Chi-square and Spearman correlation tests. The degree of agreement between two questionnaires was determined using the Kappa coefficient.
Results: 84 children aged 4-11 years (91.3%) and 8 children aged 12-16 years (8.7%) were included in the study. According to the ACT-CHILD, 40.2% of children (n=37) had controlled asthma, 44.6% (n=41) had partially controlled asthma, and 15.2% (n=14) had uncontrolled asthma. Based on the ACQ, controlled asthma was observed in 18.5% (n=17), partially controlled asthma in 35.8% (n=33), and uncontrolled asthma in 45.7% (n=42) of children. Asthma control results based on two questionnaires were significantly different from each other (P<0.001). The agreement between the ACT-CHILD and ACQ methods in evaluating children's asthma was at a weak level (P=0.014, κ=0.157), however, a significant negative correlation was observed between the scores of the ACT-CHILD and ACQ questionnaires (r=-0.588, P>0.001) which after categorizing based on age group, this correlation was confirmed only in children aged 4-11 years (r=-0.627, P>0.001).
Conclusion: Our findings showed that there is a poor agreement between ACT-CHILD and ACQ results in the assessment of asthma control. Further studies are recommended.

Abstract

Background: Lung cancer has the highest incidence and mortality rate of all cancers worldwide. In Iran, it is one of the commonly diagnosed malignancies, and its frequency is increasing rapidly. Genetic variants in DNA repair genes are linked to differences in efficiency of repairing DNA damage, which can influence lung cancer susceptibility. EXO1 is a key gene involved in the mismatch repair pathway. The K589E polymorphism in EXO1 may alter the DNA repair activity of the encoded protein and impact lung cancer risk. The aim of this study was to investigate associations between the K589E polymorphism in EXO1 and lung cancer risk in the Iranian population, and evaluate its potential as a prognostic biomarker.
Methods: This case-control study was conducted to investigate EXO1 K589E variant with susceptibility to lung malignancy in the Iranian population. One hundred patients with lung cancer as a patient group and 100 healthy individuals from Khansari Hospital located in Markazi province were studied, from January 2020 to May 2022. DNA extraction from blood samples of participants was done using a kit.  Genotype determination of both patient and control groups was done using PCR-RFLP technique. Finally, statistical results were analyzed using SPSS software and the logistic regression method.
Results: Genotype and allele frequency  analysis showed the AA genotype (P=0.004, OR=5.391, 95% CI: 1.690-17.200) and A allele (P=0.010, OR=2.851, 95% CI: 1.291-6.300) were correlated with susceptibility to lung cancer. On the other hand, people carrying the G variant allele had a lower risk of lung cancer.
Conclusion:  In summary, this study found the AA genotype and A allele of K589E in EXO1 are correlated with risk of lung cancer in Iranians, while the G allele has protective effects. The K589E polymorphism may serve as a prognostic biomarker for lung cancer susceptibility, but more studies with high population size are required.

Abstract

Background: Prolonged stay in intensive care unit (ICU) can worsen the patient's prognosis and represents a significant economic burden. Previous studies have reported the effectiveness of early mobilization in reducing length of stay in ICUs for adult patients; However, conflicting results have been reported regarding its effects on pediatric patients. Therefore, this research aimed to investigate the impact of early mobilization on the length of stay in the pediatric intensive care unit (PICU) in ventilated children.
Methods: This pilot quasi-experimental study was conducted on 60 children admitted to the Children's Medical Center hospital from March 2020 to June 2021. For the control group, routine care (standard physiotherapy) was started on the second day of intubation and continued until discharge from the intensive care unit. In this study, we used an early mobilization protocol including active and passive exercises. The intervention was implemented by Pediatric intensive care unit nurses under supervision of a pediatric critical care fellowship physician. In the intervention group, passive exercises were started on the second day of intubation. At each shift, the nurses check the level of sedation and presence of delirium in the patients using the Richmond Agitation-Sedation Scale and the Cornell Assessment of Pediatric Delirium questionnaire. If the results showed that the sedation was not deep and delirium was not present, then active exercises were initiated. If the child did not achieve an adequate score indicating the absence of deep sedation and delirium, the patient remained in the passive exercise phase. The length of stay was recorded based on the patients' records. Descriptive and inferential statistics were used for data analysis using SPSS version 23.
Results:  The results showed that there was no significant difference in the length of stay in the pediatric intensive care unit (PICU) between the control (23.20±6.34 days) and intervention (22.60±6.18 days) groups (P=0.77).
Conclusion: The implementation of early mobilization did not significantly reduce the length of PICU stay for pediatric. The researchers are advised to identify and evaluate evidence-based guidelines for implementing early mobilization in children with different diagnoses.

Abstract

Background: Preterm premature rupture of membranes (PPROM) significantly impacts perinatal mortality and maternal-fetal outcomes. The purpose of this study is to investigate the frequency of maternal risk factors, maternal and fetal outcomes and the role of care in the occurrence of outcomes.
Methods: This retrospective cross-sectional study involved 317 pregnant women with premature rupture of membranes (PPROM) at Shahid Beheshti Hospital in Isfahan, between April 2020 and April 2022. Data were collected from medical records, including demographic information, risk factors, and maternal and neonatal outcomes. Patients were categorized into two groups: those receiving care (24-34 weeks of gestation) and those undergoing pregnancy termination (less than 24 weeks or more than 34 weeks). The chi-square test was used for qualitative variables, while the T-student test was applied for quantitative variables.
Results: In this study, the average age of patients was 29.42±6.56 years. The most common risk factors for PPROM were 20.2% for abortion records, 20.2% for urinary infections, 18% for cervical insufficiency, and 13.6% for gestational diabetes. Comparing maternal outcomes between the two groups revealed that chorioamnionitis occurred more frequently in the care group (18% vs. 2%, P=0.0001), as did emergency cesarean sections (37% vs. 4.5%, P=0.0001) and NICU hospitalization (71% vs. 17%, P=0.001). In the next stage, a regression test identified the independent effects of variables on maternal and newborn outcomes without intervention or confounding factors. The analysis indicated that mothers in the care group experienced significantly more complications than those in the pregnancy termination group, and their babies also faced significantly more complications.
Conclusion: The study results indicate that a history of abortion, urinary infections, cervical insufficiency, and gestational diabetes are significant risk factors for PPROM. Expectant management of PPROM is associated with more neonatal and maternal complications than pregnancy termination. Thus, timely identification of these risk factors allows healthcare providers to educate mothers and potentially prevent and manage them, significantly reducing the incidence of PPROM and its complications.
