Background: The optimal approach to luteal-phase support in infertility treatment remains a subject of debate. This study was conducted to investigate the clinical outcomes, side effects, and patient satisfaction associated with vaginal, subcutaneous, and intramuscular progesterone administration in infertile women undergoing Frozen Embryo Transfer (FET). Methods: This three-armed randomized clinical trial assigned infertile patients eligible for FET to three progesterone treatment groups: vaginal suppositories (400 mg twice daily; n = 100), subcutaneous injections (25 mg daily; n = 102), and intramuscular injections (50 mg daily; n = 108). The primary outcomes were chemical and clinical pregnancy rates per embryo transfer cycle, with chemical pregnancy defined as beta-human chorionic gonadotropin levels > 50 IU/mL two weeks post-transfer and clinical pregnancy confirmed by ultrasound four weeks later. Exploratory outcomes included progesterone-related adverse effects and participant satisfaction, assessed via a Likert-scale survey 12 weeks post-transfer. Statistical analyses included Chi-square tests for categorical data, one-way analysis of variances, and Kruskal–Wallis tests for continuous data. Results: The intramuscular progesterone group had significantly higher chemical pregnancy rates compared to the vaginal and subcutaneous groups (41.7% vs. 26.0% and 27.5%, respectively; p = 0.026). Although the clinical pregnancy rate was also higher in the intramuscular group (32.4%) compared to the vaginal (23.0%) and subcutaneous groups (21.6%), this difference was not statistically significant (p = 0.148). Additionally, patient satisfaction was greater with vaginal and subcutaneous applications than with intramuscular injections (p < 0.001), likely due to a significantly higher incidence of side effects, such as pain and edema at the injection site, in the intramuscular group (p < 0.001). Conclusions: We found that intramuscular progesterone resulted in higher chemical pregnancy rates than vaginal or subcutaneous routes, but this did not translate into higher clinical pregnancy rates. Despite its effectiveness, intramuscular administration was associated with more adverse effects and lower patient satisfaction. Future research should explore optimizing progesterone regimens to balance efficacy and patient comfort. Trial registration: The trial protocol was registered on December 6, 2020, in the Iranian Registry of Clinical Trials (IRCT), a primary registry in the World Health Organization (WHO) Registry Network, under the registration number IRCT20141217020351N12.

Background: In recent years, Iran has witnessed a remarkable increase in the incidence of cancer. This has led to an emerging challenge in the field of oncofertility, which seeks to address the impact of cancer treatments on fertility and endeavors to preserve reproduction. The study assessed healthcare providers' awareness, attitudes, and practices regarding fertility preservation (FP) in Iran. Methods: A cross-sectional study was conducted to assess healthcare providers' knowledge, attitudes, and practices regarding oncofertility. An online self-made oncofertility survey of twenty-four items was administered to randomly selected participants from a list of healthcare providers registered with the Medical Council. The data were collected anonymously via Google Forms. Descriptive statistics, including number (n), prevalence (%), mean, and standard deviation, were calculated using SPSS 26.0. Additionally, chi-square tests were used to examine associations between categorical variables. Participants were categorized into oncology, obstetrics and gynecology (OB/GYN), and other specialties. Results: A total of 423 responses were received and analyzed. Approximately 60% of the participants were obstetrics and gynecology subspecialists, while the remaining participants represented various disciplines such as surgery (9.7%), radiotherapy (6.4%), nuclear medicine (5.2%), and pediatrics (1.4%). More than 30% of the participants had not received any specific education about oncofertility, and more than 20% stated that FP strategies are not part of their routine treatment plan for young cancer patients. Oncologists had more education than those in the Obstetrics & Gynecology group. Half the participants were unaware of insurance coverage, and FP options were infrequently recommended. Conclusions: These findings highlight the urgent need to enhance healthcare workers' knowledge and attitudes toward FP in Iran and enable them to provide comprehensive support and guidance to cancer patients.

The aim of this systematic review and meta-analysis was, for the first time, to explore whether postpartum maternal iodine status or supplementation is associated with thyroid function after delivery. The MEDLINE/PubMed, Web of Science, Embase, and Scopus were searched up to December 2021 to identify relevant studies. The pooled mean thyroid stimulating hormone (TSH), free thyroxine (fT4), and thyroxine (T4) concentrations and 95% confidence intervals (CIs) were estimated based on maternal urinary iodine concentration (UIC) (< 50, 50–100, 100–200, and > 200 µg/L) or breast milk iodine concentration (BMIC) (< 100 µg/L vs. ≥ 100 µg/L) during postpartum. A fixed/random effects model was used based on the absence/presence of heterogeneity, respectively. The study is registered with PROSPERO, number CRD42022336145. A total of 2175 studies were identified, of which 18 were eligible for the meta-analysis. The pooled values for TSH, fT4, and T4 concentrations in all subgroups were within the normal range; however, except for TSH, comparing the 95% CI showed no statistically significant difference among different subgroups. The pooled mean for TSH concentration in women with UIC > 200 µg/L was 2.23 mIU/L, whereas the corresponding values in women with UIC < 50, 50–100 and 100–200 µg/L were 0.56, 0.56 and 0.95 mIU/L, respectively. Thyroid hormones in women with BMIC < 100 µg/L and ≥ 100 µg/L were within the normal range. Iodine supplementation during postpartum was not associated with any differences in thyroid parameters, compared to non-supplemented women. In conclusion, iodine status or supplementation had no effect on thyroid hormones in postpartum women. [ABSTRACT FROM AUTHOR]

Objective(s): Anthropometric indicators are considered to be the most important health indicators for evaluating the condition of newborns. In the epidemic of infectious diseases, including the Covid-19 pandemic, pregnant women and their fetuses are among the high-risk population. The present study was conducted with the aim of investigating the changes in the anthropometric indices of newborns at birth and the factors affecting it in 6 months before and 6 months after the beginning of the covid-19 pandemic. Methods: This analytical-comparative study before and after was conducted on the number of 30540 newborns in 6 months before the covid-19 pandemic and 5009 newborns in 6 months after the covid-19 pandemic. The information was obtained from the integrated system of the Ministry of Health. The data was analyzed in SPSS 22 software. Results: The average birth weight of newborns in two periods 6 months before and after the beginning of the covid-19 pandemic was 3140.94 (469.93) and 3198.04 (446.22) grams respectively, which means that the average weight of newborns increased and statistically, there was a significant difference (P<0.001). The average height of newborns increased from 49.72 (2.31) cm in 6 months before the beginning of covid-19 to 49.78 (2.19) in 6 months after it, which increased and did not show a significant difference (P=0.125). The difference in the head circumference of newborns in 6 months before the beginning of covid-19 was 34.36(1.40) cm compared to 6 months after was 34.49(1.38), showed an increase and it was significant (P<0.001). Multivariate analysis with linear test model showed that by controlling the effect of possible confounders, being in the period before or after the covid-19 pandemic has no effect on birth weight, height and head circumference. Conclusion: The findings of this study showed that the covid-19 pandemic and its possible complications on the health of the mother and the Newborn in a short period of 6 months compared to the previous period had no effect on the average anthropometric indices of newborns.

Objective: Voiding Dysfunction (VD) is one of the most common disorders among women, which is characterized by a disorder in urination. Pelvic organ prolapse is one of the factors that can affect VD. In this study, the relationship between prolapse in the anterior, posterior, and apical areas and VD has been evaluated. Materials and methods: This is a cohort retrospective study. The participants in this study were women with VD, who referred to the pelvic floor disorders clinic of Imam Khomeini Hospital in Tehran in 2018-2020. Clinical information was obtained retrospectively from the hospital's electronic data system, also symptoms (intermittent stream, incomplete voiding, poor flow, post void dribble, straining to void, stage anterior, posterior and apical) and urodynamic parameters (including EMG, PVR100, Qmax12, and pdet20) were evaluated, which included detailed questionnaires (Urinary Distress Inventory 6 (UDI-6) and Incontinence Impact Questionnaire-7 (IIQ-7)), pelvic examination, and complete urodynamic evaluation. Results: There was a direct relationship between the age of the patients and the stage of prolapse (p<0.001). So that, the stage increased with age. In addition, it was found that the severity of urinary symptoms is related to the stage of prolapse in the apical area (p=0.001). Also, the results showed that intermittent stream symptoms and the symptoms of staining to void had a significant relationship with the stage of prolapse (III and IV) in the apical and anterior areas. Also, it was shown that only PVR > 100 had a significant relationship with the stage of prolapse in the apical area (p=0.001). Conclusion: Intermittent stream and straining to void were related to the stages of prolapse in the apical and anterior regions. It was also concluded that the greater the prolapse, the higher the value of PVR > 100. [ABSTRACT FROM AUTHOR]

Background & Objective: Prenatal invasive procedures are used for diagnostic and therapeutic purposes. The present study aimed to assess the indications and early complications of invasive diagnostic tests. Materials & Methods: This retrospective descriptive study was conducted on 708 pregnant women who were referred for prenatal invasive tests in Tehran, Iran from May 2018 to April 2022. All medical records of the participants were reviewed and entered into the study. According to the implemented procedures, medical records were categorized into two chorionic villus sampling (CVS) and amniocentesis groups. The primary outcome was determining the frequent indications of invasive diagnostic tests and post-procedure complications. Results: Six hundred and sixty-eight medical records were included. Amniocentesis procedure was performed for 624 (93.7%) and 44 cases (6.3%) underwent CVS. The most frequent indication for invasive prenatal procedures was a history of abnormal findings related to the first trimester biomarkers followed by the abnormal findings of the second trimester biochemical markers, a history of high nuchal translucency>99th percentile, and abnormal biomarkers of sequential test. Comparing post-procedure complications, the results showed no significant difference between the CVS and amniocentesis groups (P=0.845). In the amniocentesis group, 2 cases had shown spontaneous abortion and 3 leakage of amniotic fluid, as well as two cases in the CVS group, had reported vaginal bleeding. Conclusion: Our results delineated that positive fetal aneuploidy screening tests together with increased nuchal translucency were the main indications of the invasive prenatal tests. Amniotic fluid leakage, vaginal bleeding, and spontaneous abortion should be considered as procedure-related complications. [ABSTRACT FROM AUTHOR]

By increasing trend of cesarean sections (c-section) has raised the rate of health implications after c-section analogously. This study aimed to identify the factors influencing the choice of cesarean birth from obstetrician' perspective. Present study was a descriptive-analytical cross-sectional study at three medical centers dependent on Tehran University of Medical Sciences in 2022. The questionnaire included parents' demographic and economic factors, parents 'previous experiences and insistence of relatives, environmental and facilities, cultural and religious, the doctor's personal opinion, and the mother's clinical and psychological factors. In general, 67 gynecologists participated in the study. The average (SD) age and work experience of doctors was 42.95 (7.68), and 11.49 (8.35) years respectively. The most determining factors in the choice of cesarean delivery from the doctor's point of view were the maternal clinical and psychological factors. Other important factors were the culture and personal beliefs of the parents. The factor of fear of litigation and court in case of birth problems and complications was one of the other essential factors in choosing cesarean delivery. In the current study, the age and experience of the specialist doctor showed a positive correlation with the personal opinion of the gynecologists. Obstetricians and gynecologists are the final decision makers in choosing the type of delivery. To select the correct method, there is a need for a specific protocol for choosing the kind of delivery, and providing a suitable platform to resolve legal concerns and lawsuits.

Background & Objective: Despite the high efficacy of the Apgar score in finding respiratory distress, a low Apgar score doesn't necessarily indicate fetal hypoxiaasphyxia. Umbilical Artery pH (UApH) is one of the best indicators of fetal hypoxia. Therefore, it's so beneficial to consider these criteria and their relationship with the Apgar score for accurate diagnosis of prenatal respiratory distress retrospectively which reduces the unnecessary cesarean section (CS) rate. Materials & Methods: 162 full-term (=259 days) neonates delivered by CS with the diagnosis of decreased fetal heart rate (FHR) were evaluated. 1-min and 5-min Apgar scores and UApH were measured. The correlation between Apgar scores with UApH and the association between UapH and Apgar with the NICU admission were evaluated. The effect of other variables including mother's age, gravidity, gestational age, birth weight, newborn sex, and causes of decreased FHR on Apgar scores and UApH were studied as well. Results: The most common cause of decreased FHR was fetal distress, boys had higher weight (P=0.033) and lower UApH (P=0.049) than girls. Other parameters were not different significantly between both sexes. There was a positive correlation between UApH and 1-min and 5-min Apgar scores (r=0.464 and r=0.370 respectively) when controlled for birth weight (P<0.0001). The RR for NICU admission in male acidemic neonates with abnormal 1-min Apgar was 14.05 (CI95%: 5.7-34.6) in comparison to females (RR=1.06, CI95%: 1-1.26). Conclusion: Mild acidemia (UApH<7.2) at least in a male fetus would be a good predictor for postnatal complications and need for NICU admission. Future studies with more samples are suggested.

Objective: Ultrasonography (US) is an acceptable tool to diagnose the placenta accreta spectrum (PAS) among pregnant women. However, the lack of a robust criteria for diagnosis and predicting the severity of the consequences facing pregnant women requires identification of novel biomarkers. Material and Methods: This prospective, cross-sectional study was performed on pregnant women with a probable diagnosis of PAS. Their demographic information, medical and surgical history, blood loss severity (severe ≥2500 mL) following hysterectomy, and the histopathology after the surgery were collected. In addition, the Doppler imaging of both uterine arteries, including the pulsatility index, resistance index, peak systolic velocity (PSV), the PSV of the posterior part of the bladder, cervix, the largest lacuna, and the posterior lacuna of the bladder were calculated by Doppler US. Data were analyzed to investigate the relationship between Doppler markers and the severity of PAS in terms of bleeding, hysterectomy, and histopathology. Results: Fifty-one women were enrolled with a mean age of 35.4±4.11 years and 17 (33.3%) had severe bleeding. There were significant differences between median (range) bladder PSV [57 (34-90) vs. 33 (20-64); p<0.001], cervix PSV [26 (0-63) vs. 18 (0-76); p=0.04] and left uterine artery [89 (81-135) vs. 68 (61-113); p=0.045] for women with and without severe bleeding, respectively. Thirty-four (66.66%) had hysterectomy. Comparison of bladder PSV, cervix PSV, and left uterine PSV for women with and without hysterectomy were 46 (20-90) vs. 39.5 (33-46) (p=0.005), 20 (0-76) vs. 20 (14-26) (p=0.013) and 68 (61-135) vs. 82 (63-101) (p=0.003), respectively. Conclusion: Bladder PSV, cervix PSV, and uterine PSV were significantly higher in pregnant women with PAS, and they may be useful diagnostic and prognostic markers. [ABSTRACT FROM AUTHOR]

Background: Magnesium (Mg) is a vital element which plays a significant role in the human body. Respiratory distress syndrome (RDS) is one of the most common problems in preterm neonates. The current study aimed to investigate the role of serum Mg level as a prognostic factor in neonates diagnosed with RDS. Methods: This case-control study was performed in Vali-e-Asr Hospital, Tehran, Iran, for two years. A total of 100 preterm infants (50 cases, 50 controls) admitted to NICU were enrolled in this study. Demographic data, serum magnesium level, therapeutic interventions, and neonatal outcomes were investigated and the obtained data were analyzed using SPSS software. P-value less than 0.05 was considered significant. Results: Of 100 neonates, 52% were male. The mean gestational age and birth weights were 33.4 ± 2.4 weeks and 2062 ± 72 gr, respectively. The findings revealed that the mean serum magnesium level in neonates with RDS was 2.02 ± 0.57 mg/dl, while it was 2.35 ± 0.67 mg/dl for neonates in the control group (P-value=0.001). Additionally, the calculated odds ratio of 2.38 indicated a correlation between reduced serum Mg levels and the occurrence of RDS. Conclusion: The serum level of Mg among neonates with RDS was significantly lower, but the lower level of Mg was not associated with adverse outcomes in neonates. [ABSTRACT FROM AUTHOR]

Objective: Platelet Rich Plasma (PRP) is proposed to have important role in cell division and proliferation, angiogenesis and health. This study evaluates the effect of a single injection of autologous PRP on ovarian response markers in women with poor ovarian response (POR). Materials and methods: This non-randomized clinical trial was conducted between August 2020 and September 2021. Fifty six women with Bologna criteria for POR willingly chose to participate in one of the following groups: PRP for one cycle in the time of oocyte pickup (OPU) (intervention group, n= 34) or control group (n=22). The primary outcomes were: number and quality of oocytes in coming 2 cycles of ICSI, and Anti Mullerian Hormone (AMH) level two months after PRP injection. The secondary outcomes were the number and quality of embryos and chemical pregnancy rate after embryo transfer. Results: A total of 45 participants continued the study, of which 23 were in the intervention group and 22 in control group. There were no demographic differences between two groups. At a two cycle follow up, PRP group experienced a significant improvement in AMH level and there was no respective change in control group. In one year follow up the overall pregnancy rates were same in both groups (3% Vs. 0, p=.60), while there was no difference in cumulative number and quality of embryos. Conclusion: PRP injection can improve ovarian reserve marker without adverse effects. Further evidence is required to evaluate the impact of PRP on assisted reproduction outcomes.

Background: Dysphagia is a frequent complication defined as difficulty in any stage of swallowing. Infants with a history of mechanical ventilation might show difficulty in coordinating pharyngeal muscles resulting in dysphagia. Objectives: The present study aimed to show the prevalence of swallowing disorders and associated symptoms among high-risk infants with a history of prolonged mechanical ventilation. Methods: A quasi-experimental study was conducted at the Breastfeeding Research Center, Tehran, Iran. All the neonates with a history of prolonged mechanical ventilation entered the study. Parents were asked to respond to a provided questionnaire regarding their infants' swallowing disorders. Accordingly, the infants with any symptoms were considered candidates for intervention. The parents also received simple training to perform oral sensorimotor stimulation protocol for their children. Through a follow-up visit, the questionnaire was filled up for every infant. Finally, all the data related to the responses before and after interventions were compared to show the possible effects of the interventions. Results: A total of 25 infants entered the study. The mean mechanical ventilation period was 15.95 ± 6.644 days. Concerning the frequency of swallowing complications, 24 infants (96%) had different degrees of dysphagia. After 3 - 6 months of interventions, the number of cases with symptoms of coughing (P = 0.016), spitting food out by mouth (P = 0.0001), choking (P = 0.016), humid breath (P= 0.031), poor weight gain (P= 0.002), and the need to cut food into small pieces (P = 0.004) was significantly lower than the number of cases suffering from such complications before the intervention. The results also showed that after 3 - 6 months of interventions, dysphagia symptoms in 10 out of 24 infants (41.66%) entirely and in others (38.44%) partially improved. Conclusions: The results of the present study delineated that infants with a history of prolonged mechanical ventilation were at greater risk of swallowing complications. The early diagnosis and implementation of oral sensorimotor interventions could improve different symptoms of dysphagia. [ABSTRACT FROM AUTHOR]

Objectivess: This study aimed to determine the relationships between endometrial compaction and pregnancy outcome in patients receiving artificial endometrial preparation for frozen embryo transfer (FET) cycles. Materials and Methods: This prospective cohort study was performed in a university-affiliated fertility clinic from March 2020 to March 2021. The eligible women undergoing their first or second FET cycle and having the top grading cleavage stage embryos were enrolled. All patients received the same endometrial preparation regime. The alteration in endometrial thickness (EMT) between the day of progesterone initiation and the day of embryo transfer (ET) was measured using consecutive transvaginal sonography. The patients were divided into three groups based on the percentage of endometrial compaction (i.e., the difference of EMT at end of the estrogen-only phase and after three days of progesterone administration (ET day) divided by the EMT on the terminal day of the estrogen-only exposure). Results: Overall, 300 eligible women were evaluated and only 27.3% (82/300) of the studied cycles showed =5% compaction, whereas 72.6% (218/300) either expanded or showed minimal compaction. The clinical and ongoing pregnancy rates in group 2 (any expansion) were significantly higher than those in groups 1 and 3 (P = 0.002 and P = 0.01, respectively). Multivariable logistic regression test indicated that the cycles with any expansion in ET were independently associated with 3.1 times improvement in clinical pregnancy rate in comparison to those with any compaction (P = 0.002). Conclusion: Gross endometrial compaction occurred in one-third of FET cycles with no significant positive effect on pregnancy outcomes after cleavage-stage ET. [ABSTRACT FROM AUTHOR]

Background and Objectives: This study aimed to investigate epidemiology of Staphylococcus epidermidis (S. epidermidis) and Acinetobacter baumannii (A. baumannii) infections in neonatal intensive care unit (NICU) in a period of 8 years. Materials and Methods: This retrospective cohort study was conducted on 46 cases of nosocomial infection by S. epidermidis, and 44 neonates with A. baumannii in NICU of Valiasr hospital, Iran. Results: The trend of A. baumannii and S. epidermidis infection were as follows: 1 and 7 in 2014, 11 and 7 in 2015, 20 and 11 in 2016, 1 and 4 in 2017, 4 and 6 in 2018, 4 and 4 in 2019, 0 and 1 in 2020, and 3 and 6 in 2021-March 2022 respectively. Mortality proportion (%) in neonates with S. epidermidis and A. baumannii infection was at 8.3 and 32.1, respectively. There was a strong positive correlation between number of infected neonates in month and average of prescribed antibiotics before incidence of infection in every baby in that month. Fluconazole prescription before incidence of infection were associated with the A. baumannii infection in month too. Amikacin prescription had adjusted correlation on increasing of A. baumannii and S. epidermidis infection in month. Conclusion: It seems reducing of hospitalization duration and medication prescriptions management plays an important role in reducing of nosocomial infections. [ABSTRACT FROM AUTHOR]

Immune system immaturity in newborns exposes them to infections, among which bloodstream infection is of great importance due to high mortality and morbidity and treatment costs. The aim of the present study was to evaluate common pathogens in blood culture positive cases and its determinants. This study was conducted in two phases, including a cross-sectional phase to collect the cases of definitive septicemia and a case-control phase on neonates admitted to the Neonatal Intensive Care Unit of Vali-e-Asr Hospital with clinical suspicion of sepsis during 2015-2019. The eligible cases were selected based on the study criteria. After extracting descriptive statistics, to evaluate causal relationships, culture-positive and culture negative cases were compared in terms of neonatal disease in the second phase. SPSS-22 was used for data analysis. The most common bacterial families were Staphylococcus (34.30%), Acinetobacter (10.46%), and Klebsiella (7.55%), among which coagulase negative Staphylococcus was the most common organism (13.08%). The most common antibiotics prescribed were ampicillin (75.1%), amikacin (58%), and gentamycin (44.8%). Factors that had a significant association were the occurrence of septicemia were gestational hypertension, premature rupture of membranes, conjunctivitis, TORCH infections, and low gestational age. The results of this study will be helpful in anticipation and management of neonatal septicemia through shedding light on some determinants of common blood culture pathogens like infections and obstetric complications in NICU admitted neonates.

Intrauterine growth restriction (IUGR) is responsible for different post-natal adverse outcomes. This study aimed to evaluate the post-natal psychomotor development status in 6 and 12-month-old IUGR infants who received early preventive interventions. A historical cohort study was done at an Iranian Hospital (2019). The case group included one-year-old infants with a history of IUGR at birth. This group was visited every 2 months to evaluate their growth and neurodevelopmental status. Their parents had also received some training to improve their infant's sensory and motor skills. The control group comprised one-year-old healthy infants with a history of appropriate for gestational age (AGA) at birth. Data related to psychomotor developmental indices based on the ASQ questionnaire at 6 and 12-month for both groups was extracted from subjects' records. Infants' psychomotor development status was compared between groups. Forty-one infants with a history of IUGR and 43 healthy control infants were included in this study. There were significant differences between 2 groups associated with abnormalities in all evaluated psychomotor skills, including gross motor (P=0.014), problem-solving ability (P=0.049), communication (P=0.031), fine motor (P=0.016) and personal-social (P=0.016) at 6 months. After one year of family-based interventions for the case group, significant differences between groups were notable in only fine motor (P=0.016) and personal-social skills (P=0.031). At 12 months, the psychomotor disorders related to gross motor, problem-solving ability, and communication were significantly alleviated in the IUGR group. Early preventive family-based interventions can improve the neurodevelopmental outcomes in 12-month-old IUGR infants. [ABSTRACT FROM AUTHOR]

Background & Objective: It was declared that COVID-19 might be more severe in symptomatic pregnant patients. This study was conducted to examine the pathological indices of the placenta in pregnant women who were diagnosed with COVID-19. Methods: A total of 20 COVID-19-positive mothers were enrolled in this study. Detailed placental pathology findings were compared between subjects based on the history of abortion or occurrence of preterm delivery, hypertension, and diabetes. Results and Conclusion: Intervillositis was the most frequent abnormality of the placenta. There was also a significant association between abortion history and maternal vascular malperfusion (MVM; P=0.02). The placental abnormalities were found to be increased in women with COVID-19, regardless of maternal comorbidities. Further studies are needed to compare the placental pathology between COVID-19-positive women and healthy women. [ABSTRACT FROM AUTHOR]

Objective: Advances in technology and treatments have improved the survival rate of small for gestational age (SGA) infants that need more concern for their neurodevelopmental outcomes. In the present study, we hypothesized that a history of SGA may affect verbal and non-verbal intelligence indices among pre-school children. Materials and methods: A case-control study was conducted at the Tehran University of Medical Sciences (Tehran-Iran, 2020). Totally 232 children entered the study. An expert pediatrician examined all included subjects. Based on birth weight (extracted from medical records), participants were divided into the case (born SGA) and control (born Appropriate for gestational age (AGA)) groups. Wechsler Intelligence Scale (WISC) and Conners tests were implemented to assess intelligence quotient (IQ), verbal, attention, development, and executive functions. Finally, total scores were compared between groups. Results: Totally, 232 preschool children were included in the study. Of all, 114 (49.1%) and 118 (50.9%) subjects had the history of born SGA and AGA, respectively. The results related to WISC scores showed that the mean WISC-verbal score among children born SGA was significantly higher than children born AGA; (114.288 ± 18.130 vs. 108.898 ± 20.145; P=0.024). This significant difference was associated with Vocabulary (13.531 ± 2.843 vs. 12.745 ± 3.242; p=0.046) and Similarities (14.054 ± 3.630 vs. 13.279 ± 4.898; p=0.048) domains between the groups. The results related to different domains of the Conners test also showed that the mean scores of Inattention (B) and attention deficit hyperactive disorder score (D) in the case group were higher than these scores in the control group; however, these differences were not significant (4.929 ± 3.511 vs. 4.906 ± 4.300; p=0.495 &10.371 ± 5.867 vs. 10.093 ± 7.588; p=0.211). Conclusion: Our results indicated that the development of non-verbal intelligence in children born with SGA had been delayed. This finding shows that these children may need more consideration during the preschool period and after that. [ABSTRACT FROM AUTHOR]

Background: Cardiac troponin I (cTn I) has been demonstrated as a possible useful biomarker for myocardial injuries. The present study aimed to evaluate potential relationships between this biomarker and neonatal morbidities among preterm neonates. Methods: This cohort study was carried out at an Iranian Hospital (Tehran-Iran; 2021). Newly-born preterm neonates entered the study. Blood sampling was performed immediately after neonatal intensive care unit (NICU) admission and sent to the laboratory to detect levels of plasma cTnI. The correlations between the levels of plasma Tn I and each neonatal outcome were evaluated as the primary outcome. Results: A total of 101 NICU hospitalized neonates with the mean gestational age, 1st, and 5th minutes Apgar scores of 33.750±2.125 (Range: 29-37) weeks, 7.6471±1.766, and 9.188±1.205 entered the study. The mean and median of Troponin I levels were 0.131±0.126 and 0.0920 ng/ml. The results pointed out that neonates who died during hospitalization or required CPR (cardiopulmonary resuscitation) had lower troponin I in comparison with their controls; nonetheless, the differences were not significant (P=0.950 & P=0.557). The mean±SD of troponin I was not significantly different between neonates with and without PDA (p=0.741), asphyxia (P=0.298), and intubation (P=0.212). The occurrences of necrotizing enterocolitis, respiratory distress syndrome, bronchopulmonary dysplasia, intraventricular hemorrhage, and sepsis were not also significant factors for the alteration of troponin I (P>0.05). Conclusion: Since there were no relationships between cTn I and neonatal outcomes, great caution should be implemented regarding the use of single cTn I value as a diagnostic marker for short-term neonatal adverse outcomes. Further investigations with larger sample sizes are strongly suggested. [ABSTRACT FROM AUTHOR]

Purpose: Over the last decades, several twin/multiples registries have been developed worldwide, mostly concentrated in Europe and high-income countries (HICs). In Iran, we lack accurate nationwide epidemiological and biobank data on twins. We established the Iranian Newborn Multiples Registry (IRNMR) to evaluate the role of genetics and environmental factors in the variation of phenotypes among newborn monozygotic (MZ) and dizygotic (DZ) twin pairs. IRNMR is a multicenter hospital-based registry. Materials and methods: In the pilot phase, we collected epidemiological data from multiples born in Imam Khomeini Hospital complex and Aban Hospital located in Tehran, the capital of Iran, with a population exceeding 8 million, Allameh Bohlool Gonabadi Hospital, Gonabad, Razavi Khorasan, and Shahid Sadoughi Hospital, Yazd, Iran. Results: The IRNMR has recruited 457 sets of newborn twins and multiples so far. We hold follow-up sessions by mother and child health professionals to monitor multiples' growth, development, diseases, and mortality. Conclusions: We successfully developed a newborn multiples registry in Iran. This registry will create an invaluable database to study the relative influence of genes and environmental factors on various chronic diseases, growth, development, and behavioral disorders. We intend to collaborate with other centers to develop a large multicenter nationwide multiple birth registry and biobank in Iran. [ABSTRACT FROM AUTHOR]

Objective: This study aimed to investigate and identify the psychosocial factors that are associated with paternal postpartum depression. Materials and methods: A longitudinal correlation study with 150 fathers was performed with three time frames (late pregnancy, postpartum, and four weeks postpartum). The Edinburgh Postnatal Depression Scale assessed those with depression (38.7%; n=58) and those without depressive symptoms (61.3%; n=92). Psychological variables related to paternal depression were also assessed through questionnaires. Results: Psychological variables such as marital adjustment and stress had a significant relationship with paternal depression. In addition, depressed fathers experienced less marital compatibility and more tension than non-depressed fathers. Conclusion: These findings emphasize the importance of considering the psychosocial variables that affect paternal psychological health. Mental health professionals may be able to reduce mental disorders, stress, psychological distress, and marital maladjustment in fathers with appropriate psychological interventions.

Introduction: Caesarean section (C/S) rates have significantly increased across the world over the past decades. In the present population-based study, we sought to evaluate the association between C/S and neonatal mortality rates.Material and Methods: This retrospective ecological study included longitudinal data of 166 countries from 2000 to 2015. We evaluated the association between C/S rates and neonatal mortality rate (NMR), adjusting for total fertility rate, human development index (HDI), gross domestic product (GDP) percentage, and maternal age at first childbearing. The examinations were also performed considering different geographical regions as well as regions with different income levels.Results: The C/S rate and NMR in the 166 included countries were 19.97% ± 10.56% and 10 ± 10.27 per 1000 live birth, respectively. After adjustment for confounding variables, C/S rate and NMR were found correlated (r = -1.1, p < 0.001). Examination of the relationship between C/S rate and NMR in each WHO region resulted in an inverse correlation in Africa (r = -0.75, p = 0.005), Europe (r = -0.12, p < 0.001), South-East Asia (r = -0.41, p = 0.01), and Western Pacific (r = -0.13, p = 0.02), a direct correlation in America (r = 0.06, p = 0.04), and no correlation in Eastern Mediterranean (r = 0.01, p = 0.88). Meanwhile, C/S rate and NMR were inversely associated in regions with upper-middle (r = -0.15, p < 0.001) and lower-middle (r = -0.24, p < 0.001) income levels, directly associated in high-income regions (r = 0.02, p = 0.001), and not associated in low-income regions (p = 0.13). In countries with HDI below the centralized value of 1 (the real value of 0.9), the correlation between C/S rate and NMR was negative while it was found positive in countries with HDI higher than the mentioned cut-off.Conclusions: This study indicated that NMR associated with C/S is dependent on various socioeconomic factors such as total fertility rate, HDI, GDP percentage, and maternal age at first childbearing. Further attentions to the socioeconomic status are warranted to minimize the NMR by modifying the C/S rate to the optimum cut-off. [ABSTRACT FROM AUTHOR]

Background: Peripherally Inserted Central Catheter (PICC), which is inserted through peripheral veins into the superior or inferior vena cava, is used to inject medications or parenteral nutrition in neonates with long-term hospitalization in the intensive care unit. In this study, we assessed the complications of PICC in neonates admitted to the intensive care unit in hospital. Materials and Methods: In the present retrospective cohort, neonates admitted to the Neonatal Intensive Care Unit (NICU) of Valiasr Hospital during 2015-2018 had been divided into two groups with PICC and without it. Data included the occurrence of septicemia, tachycardia, perforation of large veins, pulmonary hypertension, cardiac tamponade, pericardial effusion, catheter site necrosis, hemorrhage, anemia, pleural effusion, ascites, phlebitis of catheter track and neonatal death, which were collected, using the comprehensive neonatal registry of Valiasr Hospital. Data analysis was performed with regression, mantel-haenszel and independent t-test. Results: Data from 174 neonates with PICC were compared to 207 infants with classic IV-Line. In the exposure group, the gestational age and birth weight were lower. Based on the results of the double logistic regression test, septicemia and hemorrhage in the injection site, independent of other variables, were related to the use of PICC and the risk of septicemia or hemorrhage in the injection site was significantly reduced if PCIC was used (p < 0.01). Conclusions: Using the PICC as a therapeutic procedure in hospitalized neonates in the NICU is a safe method. By improving its replacement skills among physicians and nurses, its side effects are minor and negligible. [ABSTRACT FROM AUTHOR]

BACKGROUND: The poor ovarian response is the most important limiting factor in the success of in vitro fertilization (IVF). The aim of this study was to evaluate the outcome of intraovarian injection of autologous platelet-rich plasma (aPRP) on the oocyte number and IVF outcomes in poor ovarian responders (POR). METHODS: This quasi-experimental study was performed from August 2021 to December 2021, in Vali-e-Asr Infertility Clinic affiliated with Tehran University of Medical Sciences, Tehran, Iran. There were 12 POR patients selected based on the criteria of Bologna group 4 who underwent two IVF cycles with similar antagonist regimens in a 70-day-interval. Immediately after the Oocytes Pick-Up (OPU), there was a 4cc of autologous PRP multifocal intramedullary injection done into their right ovaries in the first IVF cycle (case group). On the other hand, their left ovaries were considered as the control group. The patients underwent the second IVF cycle after 70 days. RESULTS: Those who had undergone aPRP experienced a significant increase of the mean of antral follicular count (AFC) (from 1.91±0.79 to 2.50±0.90, p=0.043). There was a significant increase in the number of embryos from the right ovary (intervention group) compared to the left ovary (control group) after PRP, but there was no significant difference in the number of embryos in the right ovary before and after the intervention (from 0.25 ±0.45 to 1.08±0.79, p=0.705). There was no significant change in the number of oocytes, AMH, and FSH in the case and control groups before and after the intervention (p>0.05). CONCLUSION: According to the results of this study, it seems that in females with POR, intraovarian aPRP had no effect on the outcomes (embryos number, number of oocytes, FSH and AMH level), except for an increase in AFC.

Spirometry is an important measurement in detecting and monitoring of chronic obstructive pulmonary disease. The validity of the multi-ethnic Global Lung Function Initiative 2012 (GLI-2012) spirometric norms have been debated in some countries. The aim of the present study was to evaluate the applicability of the GLI reference norms in the Iranian population. A cross-sectional study was performed on 622 healthy non-smoker population (204 males and 418 females, age range: 4 ± 82 years) between July 16 and August 27, 2019 in Iran. Z-scores for spirometric data [FEV1 (forced expiratory volume in 1 s), FVC (forced vital capacity) FEV1/FVC, and FEF25–75% (forced expiratory flow averaged over the middle portion of FVC)] were calculated. According to the agreement approved, a mean Z-score outside the range of ± 0.5 was considered clinically significant. The mean (SD) Z-score values of FEV1, FVC, FEV1/FVC and FEF25–75% were 0.44 (1.21), 0.49 (1.14), 0.11 (1.03), and − 1.13 (0.99) in males and 0.61 (1.14), 0.89 (1.26), 0.17 (0.88) and − 0.49 (0.96) in females, respectively. The Z-score of FEV1/FVC was below the lower limit of normal (LLN) in 3.43% of men and 2.01% of women (in ≥ 21 years), while these values were significantly higher in people under 21 years old (46.2% in boys and 40.0% in girls). The GLI reference values are not perfect for the Iranian population, especially in children below 10 years old. The use of the GLI reference values was appropriate in population above 21 years; however, they would overestimate the prevalence of airway obstruction in individuals below 21 years.

Background: The placental examination provides important information about the effect of maternal abnormalities on the placenta or the cause of preterm delivery, fetal growth restriction, or fetal neurodevelopmental damage. In this study, the frequency of placental pathologies of patients in a tertiary hospital was investigated. Methods: In this longitudinal and cross-sectional study, all removed placentas after any type of pregnancy termination referred to a pathological examination, within 1 year (2019–2020). All placentas were examined macroscopically and microscopically by two pathologists. Results: Unfortunately, because of the COVID-19 pandemic, the number of pregnant women in our hospital declined. A total of 258 placentas were examined. The type of delivery in 193 cases (79.4%) was cesarean section and 50 cases (20.6%) had a vaginal delivery. In the pathological assessment of placentas, 238 (92.2%) cases were normal and 20 cases (7.8%) were abnormal. Infarct and chorioamnionitis were the pathologies with higher frequencies (4.3% and 2.7%, respectively). Intra-uterine fetal death (p = 0.701), preeclampsia (p = 0.51) had no significant difference was seen in normal and abnormal placentas. Maternal age (p = 0.83), gestational age based on the last menstrual period (p = 0.38), and gestational age based on the first ultrasound (p = 0.78) did not show a significant relationship with any of the pathological complications categories. Conclusions: Pathological examination of the placenta from all live-birth deliveries is not worthwhile, and it's recommended to modify the guidelines as to when the placenta is submitted for pathological evaluation.

Advances in medicine and medical technology have presented new moral challenges in terms of the management of extremely preterm infants and newborns with severe anomalies and advanced asphyxia. The aim of the present study was to examine the attitudes of health care providers and parents regarding decisions about the treatment of these neonates. The attitude of the Shia clerics is assessed in this study as well. In this qualitative content analysis research, data were collected through semi-structured interviews and focus group discussions (FGDs) with 98 participants, including physicians, nurse practitioners, medical ethicists, Shia clerics, and parents. Purposive sampling was employed by selecting those members of the community whom we thought would provide us with the best information and were also eager to participate. Data collection continued until data saturation was reached. Data analysis was carried out using conventional content analysis. Analysis of the data resulted in the extraction of 332 codes along with the following four categories: the necessity for preparation of a national guideline for the management of neonates with poor prognosis, the establishment of hospital neonatal-management committees, decision-making regarding the limits of viability, and parental support. This study affirms that the responsibility in terms of decision-making for neonates with poor prognosis lies upon hospital neonatal-management committees based on approved national guidelines such that decisions are made according to the aforementioned guidelines, Islamic moral codes, and scope of services available in medical units. This study dismisses individual decision-making and underlines the responsibility of a hospital neonatal-management committee in making decisions based on approved guidelines that conform to the regulations of national law and Islamic moral codes that determine the continuation or withdrawal of medical care and treatment of infants with a poor prognosis while bearing in mind that regulations, hospital facilities, resources, and other conditions differ in various hospitals within the country and with developed countries.

Background: The aim of the present study was to compare the six-month results in terms of prolapse symptoms in postmenopausal patients with advanced pelvic prolapse (POP) who underwent LeFort colpocleisis surgery or with pessary placement. Methods: In this prospective cohort study, 110 older women were enrolled from April 2016 to January 2018. The women were diagnosed with stage III or higher genital prolapse according to the POP quantification (POP-Q) system. The patients were divided into two groups: surgical (LeFort colpocleisis surgery; n=55) and non-surgical (pessary placement, n=55). The study population underwent LeFort colpocleisis surgery or pessary placement in two university clinics (Beheshti or Alzahra Hospitals). All patients completed the Pelvic Floor Distress Inventory Questionnaire-20 (PFDI-20). The main short-term outcome measurement (six months) was the manifestation of a pelvic prolapse in the groups. Results: The patients had a mean age of 68.98±8.79 years in the non-surgical group and 64.76±7.04 years in the surgical group. The analytic results showed a significant difference between the two groups (P=0.006). After treatment, the prolapse symptoms improved in both groups (p<0.001). However, the total PFDI-20 score did not show any significant differences at the end of the six-month follow- up (P=0.19). Conclusion: Both strategies (pessary placement or LeFort colpocleisis surgery) provide a short-term option for the treatment of older women with stage III or higher POP. The findings of this study could assist with treatment options and allow better guidance for older patients with symptomatic POP in the treatment decision process. [ABSTRACT FROM AUTHOR]

Background: Prenatal corticosteroid administration in preterm labor is one of the most important treatments available to improve neonatal outcomes; however, its beneficial effects on late preterm infants (after the 34th week of gestation) remained unknown. We aimed to assess the effects of betamethasone on the clinical condition of the late preterm infants born between 34 and 36 weeks of gestation.Methods: This retrospective cohort study was performed on 100 consecutive infants born between 34 and 36 weeks of gestation and received betamethasone before delivery as the cases and 100 neonates with the same delivery conditions but without receiving betamethasone. All neonates were followed up within hospitalization to assess the neonatal outcome.Results: The neonates receiving betamethasone suffered more from respiratory distress syndrome (49% versus 31%, p = 0.008, RR = 1.59 95% CI (1.12-2.27)) and requiring more respiratory support (71% versus 50%, p = 0.002, RR = 1.43 95% CI (1.13-1.80)) as compared to the control group. There was no difference between the two groups in other neonatal adverse events or death.Conclusion: the use of betamethasone in the late preterm period (after 34 weeks of gestation) has no beneficial effects on lung maturity or preventing neonatal adverse outcomes, even may lead to increase the risk for RDS and requiring respiratory support.

Due to the unique nature of the neonatal intensive care unit (NICU) and its moral distress, this study aimed to investigate moral distress in the NICU. This cross-sectional study was conducted on 234 physicians and nurses working in the neonatal wards of eight hospitals. The Corley’s Moral Distress Scale was used to collect data. Findings showed that 25 of the participants were physicians and 209 were nurses. The intensity and frequency of distress among physicians and nurses were assessed as moderate. The mean intensity and frequency of moral distress among nurses and physicians were 48.3%, 41.5% and 46.46%, 15.62% respectively. The results showed that the mean intensity and frequency of distress were higher, however not significantly, among nurses. The intensity and frequency of moral distress had a statistically significant and direct correlation with the intention to leave and the number of staff in each working shift among the nurses. Moral distress in the NICU practitioners was moderate, so addressing this issue and trying to alleviate it was important. Identifying the causes behind moral distress can help adopt appropriate measures to prevent and reduce them. [ABSTRACT FROM AUTHOR]

Background: There is limited information on neonatal outcomes in complicated pregnancies with abnormal placentation. The aim of this study was to assess the neonatal outcomes of abnormal placentation.Methods: In this case-control study, known cases of abnormal placentation between the years 2010 and 2017 were extracted. The case group consisted of pregnant women with abnormal placentation (172 cases), while controls were selected from repeated cesarean section cases with normal placentation (341 people).Results: In the case group, 145 cases (84.3%) had placenta accreta, 12 cases (7.07%) had placenta increta and five cases (8.7%) had placenta percreta. Characteristics significantly more common in the case group included lower mean gestational age and average neonatal weight (p < .001), low birth weight (LBW) and small for gestational age (SGA) (p < .001), admission to the NICU (p < .001), higher average number of hospitalization days in the NICU (p < .05), lower average 5-minute Apgar scores (p < .001), neonatal seizure (p = .004), cranial hemorrhage (p = .037), anemia (p = .002) and thrombocytosis (p = .029). The occurrence of abnormal placentation was associated with some underlying maternal characteristics such as high maternal age (p = .34), lower maternal weight (p = .044), multiparity (p = .11), history of previous abortion (p = .036), and history of cesarean (p = .001). The prevalence of placenta previa was significantly higher in the case group (p < .001).Conclusion: The presence of placenta previa has a close relationship with abnormal placentation and is considered to be a potential risk factor for LBW, SGA, lower 5 minutes Apgar scores, first-day seizure, cranial hemorrhage, the necessity for NICU admission and occurrence of anemia and thrombocytosis in neonates.

Background: Coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread worldwide, causing a significant public health disaster. Objectives: The present study aimed to evaluate the clinical features and laboratory data of neonates born to mothers with COVID- 19. Methods: A retrospective multicenter cohort study was conducted from March 20 to September 5, 2020, on all neonates born to mothers with positive real-time reverse transcriptase-polymerase chain reaction for SARS-CoV-2 or clinically suspected COVID-19. Neonates enrolled in this study were from five different hospitals affiliated with the Tehran University of Medical Sciences. All the newborns were tested for SARS-CoV-2 using nasopharyngeal swabs during the first 24 - 48 hours of life, and a second-time swabbing was performed as indicated at subsequent visits. All categorical data were manifested as frequency (%), and continuous data were shown as mean±SD. Results: Forty-four neonates born to 39 infected mothers were evaluated during the study period. Nineteen women had complications during pregnancy, including hypertensive disorders, gestational diabetes, preterm labor, etc. Besides, 54.5% of the neonates were born preterm. The mean gestational age and birth weight were 35.11 ± 4.01 weeks and 2,567 ± 898 g, respectively. Fifteen (34.1%) neonates were symptomatic at birth, and during the observation, more neonates became symptomatic. Finally, 27/44 (61.3%) neonates became symptomatic, and 17/44 remained asymptomatic. The most common clinical manifestations were respiratory distress (77.7%), followed by fever or hypothermia (18.5%), gastrointestinal problems (14.8%), and neurologic findings (3.7%). Also, the most common clinical feature of eight neonates with positive RT-PCR was respiratory distress, followed by neurologic symptoms, temperature instability, and gastrointestinal disorder, in sequence. Few abnormalities were seen in laboratory findings. Chest Xrays were abnormal in 22.2% of the neonates. Conclusions: The SARS-CoV-2 infection during pregnancy may cause severe maternal and neonatal morbidities. Neonates with positive SARS-CoV-2 may demonstrate a spectrum of clinical features. The most common feature of neonates born to mothers with COVID-19 was respiratory distress. [ABSTRACT FROM AUTHOR]

Aim: This study was performed to evaluate the effects of vaginal versus intramuscular progesterone supplementations on the mood, quality of life, and metabolic changes in pregnant women with the history of previous preterm birth.Methods: This study was conducted as a prospective, randomized, open label, clinical trial evaluated 100 pregnant women who referred for prenatal visit, with 16-17 weeks of gestation from September 2014 through October 2015. The mothers were then randomly allocated into two groups: the vaginal progesterone group to receive 400 mg cyclogest vaginal suppositories (Actavis, UK limited, England) once daily, and the intramuscular progesterone group to receive weekly intramuscular injections of 250 mg of 17-hydroxyprogesterone caproate (17-HPC) (Bayer Schering Pharma, Germany), starting from the 16th to the 35th weeks of pregnancy. Demographics, medical and obstetrical history, sleeping disturbances, alteration in sexual desire, nausea/vomiting, serum levels of fasting blood sugar (FBS), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were evaluated, first and 8 weeks later.Results: About 11 (11.2%) screened positive for psychosocial disorders; 25 (25.5%) had sleep disturbance, 11 (11.2%) had alteration in sexual desire, and 29 (29.6%) had nausea/vomiting upon enrollment. After 2 months of receiving daily vaginal progesterone, there was a significant increase in the GHQ-28 score (p < .001), and rates of positive screening for psychosocial disorders (p = .001) in this group. No statistically significant differences were observed in the HDL levels (p = .06), LDL levels (p = .15), rates of impaired FBS (p = .08), nausea/vomiting (p = .2), sexual desire alteration (p = .56), and sleep disturbance (p = 1) in the participants who were randomized to this group.Conclusion: Our results indicated that psychosocial disorders increased significantly at 24th week gestational age after 2 months of progesterone consumption in both groups which could show psychological impact of progesterone regardless of the route of consumption. This calls for higher psychological attention in these women. [ABSTRACT FROM AUTHOR]

Background: Lead as a toxic heavy metal can readily transfer through the placenta; this condition may increase the risk of lead toxicity for a developing fetus. Therefore, we undertook this study to evaluate the association between umbilical cord blood lead levels and the risk of intrauterine growth restriction (IUGR) occurrence.Methods: A cross-sectional study was done at an academic hospital (Tehran, Iran, 2017). The population study was term and IUGR complicated neonates. Immediately after birth, 3-ml umbilical cord blood was collected in some tubes and sent to a laboratory to assay plasma lead levels. Demographic data related neonates and their mothers were gathered from the medical record. All recorded data were analyzed to compare the cord blood lead levels among normal term and IUGR neonates as the primary outcome.Results: Totally 152 neonates, 76 in each group with inclusion criteria entered the study. Of all neonates, 71 subjects (47%) were male. The mean (±SD) cord blood lead levels was 6.5 ± 4.2 µg/l. Of all neonates, 102 (67.1%) had high cord blood lead levels (≥5 µg/dl) and 50 subjects (32.8%) had low cord blood lead levels (<5 µg/dl). The mean gestational age, birth weight and head circumference of term neonates were significantly higher than IUGR complicated neonates (p-value = .0001). On the other hand, no significant difference was observed between two groups regarding the mean cord blood lead concentrations (6.2 ± 2.2 and 6.8 ± 5.6 µg/dl; p-value = .855). ANOVA analyses showed no relationships between cord blood lead levels and all assessed qualitative variables except from mother's educational status (in IUGR group; p-value = .048 and in term group; p-value = .010).Conclusion: Our results highlighted that IUGR occurrence was not associated with fetal blood lead levels alone. Moreover, highly educated mothers had neonates with low blood lead levels, showing that maternal education may be a potentially protective factor against this toxin exposure in newborns. The majority of neonates in the present study had high blood lead concentrations that show a necessity for more efforts and strategies regarding protection against potential deleterious effects of lead toxicity.

High-level toxic metal exposure has become rare in the recent years. Although, it has not known whether relatively lower exposure may adversely affect human reproductive system. Spontaneous abortion (SA) is a serious reproductive problem, which, in many cases, the cause(s) is not clearly understood. To assess the relationship between prenatal blood level of metals and SA risk, we compared blood concentration of some heavy metals in samples taken from mothers recruited in Tehran Environment and Neurodevelopmental Defects (TEND) study conducted on apparently healthy pregnant women in Tehran, Iran who subsequently experienced spontaneous abortion with mothers who their pregnancy ended to live births. During early gestation, 206 women were enrolled to the survey and followed up till fetal abortion or baby deliveries occur. Blood metal concentrations were measured using an inductively coupled plasma mass spectrometer. The mean blood levels of lead, antimony, and nickel were higher in SA than ongoing pregnancy; however, this difference was not statistically significant. When adjusted for covariates, the logistic regression analysis showed significant association between maternal age and the risk of SA in all models. Among toxic metals only antimony had a noticeable positive relation with the risk of SA (OR: 1.65, 95% CI:1.08–2.52, P value: 0.02). Pearson's correlation coefficient showed significant (P < 0.05) positive correlations among prenatal blood metals levels, except for nickel. Although the present study failed to provide strong evidence for the effects of toxic metals on the occurrence of SA at the relatively low-levels, these metals should be avoided in women who plan pregnancy and/or during the early stages of gestation to prevent the chance of adverse effects.

Background: Previous studies have indicated that the majority of cases with "failed" results related to transient evoked otoacoustic emissions (OAE) test have the normal hearing. The present study aimed to assess the possible relationships between perinatal factors and the false-positive OAE results.Methods: A case-control study was carried out in an Iranian Hospital in 2020. Based on the OAE results on the first day of life, newborns were divided into 2 groups; Control group included subjects with "Pass" OAE results. Every neonate with "Fail" OAE result was referred for auditory brainstem response (ABR). Neonates with bilateral fail OAE but normal ABR results (false-positive OAE) were considered as the case group. All recorded data were analyzed to assess the possible correlations between maternal/neonatal factors and the false-positive OAE results.Results: One hundred and eighty-one neonates entered the study. Of all included neonates, 87 (48.1%) cases showed bilateral fail OAE and 94 (51.9%) subjects passed the OAE test. Normal ABR results (false-positive OAE) were observed in all cases with bilateral fail OAE. Comparisons of variables affecting the OAE results showed that of all perinatal factors, neonate's sex (p = 0.046) and cesarean section (p = 0.003) were the only influencing factors that increased the risk of false-positive OAE results.Conclusion: Based on the results, the cesarean section delivery and neonate's male sex increased the risk of false-positive results related to OAE test. Implementing other screening tests such as ABR or Automated ABR as the initial screening test could be suggested for such cases. [ABSTRACT FROM AUTHOR]

Objective: The current systematic review aimed to provide comprehensive d ata on the effects of iodine supplementation in pregnancy and investigate its potential bene fits on infant growth parameters and neurocognitive development using meta-analysis. Methods: A systematic review was conducted on trials published from Jan uary 1989 to December 2019 by searching MEDLINE, Web of Science, the Cochrane Library, Scopus, and Goog le Scholar. For most maternal and neonatal outcomes, a narrative synthesis of the data was performed. For birth anthropometric measurements and infant neurocognitive outcomes, the pooled standardized mean differences (SMDs) with 95% CIs were estimated using fixed/random effect models. Results: Fourteen trials were eligible for inclusion in the systematic review, of which five trials were included in the meta-analysis. Although the findings of different thyroid paramet ers are inconclusive, more consistent evidence showed that iodine supplementation could prevent the increase in thyroglobulin concentration during pregnancy. In the meta-analysis, no differences were found in weight (-0.11 (95% CI: -0.23 to 0.01)), length (-0.06 (95% CI: -0.21 to 0.09)), and head circumference (0.26 (95% CI: -0.35 to 0.88)) at birth, or in cognitive (0.07 (95% CI: -0.07 to 0.20)), language (0.06 (95% CI: -0.22 to 0.35)), and motor (0.07 (95% CI: -0.06 to 0.21)) development during the first 2 years of life in infants between the iodine-supplemented and control gro ups. Conclusion: Iodine supplementation during pregnancy can improve the iodine status in pregnant women and their offspring; however, according to our meta-analysis, there was no evidence of improved growth or neurodevelopmental outcomes in infants of iodine-supplemented mothers.

Background: Myasthenia gravis (MG) is a chronic neuromuscular disease, which physically and mentally affects the patient's life, with depression being one of the most important psychological complications in these patients. This study aims to investigate the prevalence of depression and its associated factors in a group of Iranian patients with MG. Methods: This was a cross-sectional study in which consecutive patients diagnosed with MG who referred to two referral neuromuscular clinics affiliated to the Tehran University of Medical Sciences, Tehran, Iran, were evaluated for eligibility. Patients with a previously known psychiatric disorder and those with a family history of mental disorders were excluded. Eligible patients were interviewed and screened for depression through the administration of the Hamilton Depression Rating Scale (HDRS) and the Iranian version of Beck Depression Inventory-II (BDI-II). Results: A total of 62 patients participated in this study. The total prevalence of depression according to the HDRS and BDI-II scores was 64.5% and 53.2%, respectively. The mild depression was the most frequent level of depression based on the HDRS (33.9%) and BDI-II (22.6%) scores. None of the variables, including age, sex, duration of the disease, and dosages of prednisolone, pyridostigmine, and azathioprine, were correlated with the severity of depression. The number of academic years was the only variable associated with the lower HDRS score (P = 0.037). Conclusion: Based on the current findings, depression was common among Iranian patients with MG. The severity of depressive symptoms was unrelated to age, sex, marital status, duration of the disease, the daily dosage of medications, and thymectomy status. Further investigations are needed to reveal the exact burden of depression in patients with MG and address the importance of preventive interventions for improving the quality of life (QOL) in these patients.

Background: Appropriate and accurate easy access tools are necessary to overcome complications from malpositioned line tips of peripherally inserted central catheters (PICCs) in critically ill neonates. Ultrasound is a radiationless, cost-beneficial, and timesaving method that allows medical personnel to manipulate the line and correct possible malposition of this tip. In addition, it reduces the need for a second radiography. Objectives: We compared the effectiveness of sonography with radiography for confirmation of the line tip placement. Methods: This prospective descriptive-analytical study was conducted in the Neonatal Intensive Care Unit (NICU) in Tehran Children's Medical Center (tertiary level), Tehran, Iran. Neonates who were candidates for PICC implantation according to the ward's protocol were enrolled in the study. Radiography and sonography were performed after catheter insertion by a radiologist blinded to the preliminary radiographic reports. The results of both methods were compared and interpreted by statistical analysis using the chi-square and Pearson correlation tests. Results: A total of 90 infants, 45 (50%) males and 45 (50%) females, were assessed. We noted that 17 (18.8%) cases had malpositioned tips according to the radiographs. Malpositioning of the line tips were identified in 21.1% of cases by sonography (P ≤ 0.05), which indicated a higher accuracy for sonography compared to radiography. Both methods were appropriately correlated regardless of the underlying variables. Sonography had a sensitivity of 100% and specificity of 89.5%, a positive predictive value (PPV) of 97.3%, and a negative predictive value (NPV) of 100%. Conclusions: Our findings show that sonography can be a more accurate, safer bedside tool, with fewer complications compared to radiography in PICC tip placement determination in neonates. Multi-center studies with increased sample sizes should be performed to confirm replacement of radiography by sonography as the gold standard test for confirmation of PICC tip positioning.

Oral ibuprofen has been known as a conventional treatment for closing patent ductus arteriosus (PDA) in preterm newborns. Since the use of it might lead to various side effects, other treatments needed to be evaluated. Therefore in a prospective study, we compared the efficacy and safety of intravenous acetaminophen versus oral ibuprofen for the closure of PDA. In this study which was done prospectively and under control, 50 preterm neonates with gestational ages and weights less than 37 weeks old and 2500 grams, respectively, who had PDA, large enough hemodynamically, were included in the study. The patients were divided into two groups: A (intravenous acetaminophen) & B (oral ibuprofen). The two groups were given at most two 3-day courses of the medication (the second course if necessary) and evaluated at the end of each course by echocardiography so as to determine the response to the treatment at each step. The rate of ductal closure, the need for additional treatment, side effects, complications and the newborn's clinical status were recorded. The rate of ductal closure in the both groups after one course of treatment was similar and showed no meaningful significance statistically (P=0.306). But that of the side effects was much higher in group B with a P=0.021. Intravenous Acetaminophen is not only as efficacious as oral Ibuprofen for the treatment of PDA in preterm infants, but also is less likely to lead to side effects and complications.

Objective: We aimed to identify factors influencing pregnant women's use of patient decision aids (PtDA) and decision making on prenatal screening. Materials and methods: This qualitative study was conducted between July 2019 and June 2020 in Tehran, Iran. The sample included 26 pregnant women selected by purposive sampling. The participants used a prenatal screening PtDA, then interviewed about factors that would influence their decision making and use of decision aids. The data were analyzed by conventional content analysis. Results: Three categories were identified for the process of and factors influencing decision making, including the current decision making process, expected decision making process, and factors influencing decision making. Also, five categories were identified as factors affecting the use of PtDAs, including the content of decision aids, the appearance of decision aids, the decision aid platform, the provision of decision aids, and the sub features of decision aids. Conclusion: To design, develop, and implementation of PtDAs for pregnant women, one should identify the factors affecting pregnant women's decision making and the use of decision aids. This study helped to the identification of these factors, which is the first step towards the use of PtDAs by pregnant women and their participation in decision making. [ABSTRACT FROM AUTHOR]

Background: Respiratory distress syndrome (RDS) is acommonlungproblem in neonates born before 28 weeks of pregnancy. The current study aimed to assess the clinical outcomes of Nasal Continuous Positive Airway Pressure (NCPAP), as compared to humidified high flow nasal cannula (HHFNC) in the treatment of premature neonates with RDS. Methods: This randomized control trial was conducted on 60 preterm neonates (gestation <34 weeks and birth weight <2,000 g) with mild to moderate RDS (respiratory severityscore of 4 to 7) andoxygen requirement 60% or less. They were randomly assigned to either NCPAP or HHFNC groups. Treatment failure in the first 72h after birth was the primary outcome. Secondary outcomes included Pneumothorax, patent ductus arteriosus (PDA), chronic lung disease, surfactant injection, tracheal intubation, necrotizing enterocolitis (NEC), several days of delay in establishing full enteral feeds, extended length of hospital stay and oxygen therapy days, and death. Data were analyzed in SPSS software (version16) usingindependent t-test, chi-square, and logistic regression statistical testsat 95% significant level. Results: There were no significant differences in primary and secondary outcomes, including pneumothorax, patent ductus arteriosus (PDA), chronic lung disease, surfactant injection, tracheal intubation, death, necrotizing enterocolitis (NEC), days of delay in establishing full enteral feeds, duration of hospitalization, and the number of the days for oxygen requirement between NCPAP and HHFNC groups. Conclusion: HHFNC and NCPAP techniques have the same efficacy in the treatment of RDS in neonates, and there was no difference between the two techniques in terms of treatment failure and clinical outcomes. Since HHFNC is less invasive with the same efficacy compared to CPAP, we recommend that it can be used as a primary modality in preterm neonates with RDS. [ABSTRACT FROM AUTHOR]

Background: Risk scoring systems evaluate neonatal outcomes using perinatal and neonatal status. The present study aimed to predict the mortality risk of preterm or low birth weight infants using the Clinical Risk Index for Babies (CRIB-II) and Score for Neonatal Acute Physiology Perinatal Extension (SNAPPE-II) scoring systems. Methods: This prospective cohort study investigated the preterm neonates admitted to the Neonatal Intensive Care Unit (NICU) of Vali-e-Asr Hospital, Tehran, Iran, with the birth weight of ˂1500g or a gestational age˂32weeks using the CRIB-II and SNAPPE-II scoring systems within the first 12 h after birth. The area under the curve, sensitivity, specificity, positive and negative predictive values of the scoring systems, as well as the association between neonate factors and neonatal death were calculated in this study. Results: Out of 344 neonates under study, 253 casessurvived after 24hof birth and 91 newborns died. The total CRIB-II scores in survived and deceased infants were 6.12 and 10.28, respectively. The area under the receiver operating characteristic (ROC) curve with a cut-off point of 8.5 was obtained at 0.838. Moreover, the sensitivity, specificity, positive predictive value, and negative predictive value were estimated at 74.4%, 78.65%, 55.37%, and 89.68%, respectively, for the CRIB-II system. Total scores of SNAPPE-II in survived and deceased infants were 16.9 and 51.6, respectively. The area under the ROC curve with a cut-off point of 27.5 was determined at 0.887. Sensitivity (84.44%) and specificity (79.05%) were calculated for the SNAPPE-II. Furthermore, positive and negative predictive values were 58.91% and 93.46%, respectively. Conclusion: This study demonstrated that the CRIB-II and SNAPPE-II scoring systems can be useful mortality predictors for at-risk neonates. [ABSTRACT FROM AUTHOR]

Objective: The coronavirus disease 19 (COVID-19) is a highly transmittable and pathogenic viral infection, causes severe acute respiratory syndrome and was spread throughout the world in early 2020. The effects of vitamin and micronutrient supplements on the prevention and treatment of COVID- 19 seems challenging in scientific considerations. On the other side generally, experts warn against overconsumption of these supplements. Materials and methods: This study aimed to investigate the vitamin and micronutrient supplementation usage pattern in past history of patients with COVID-19 via a cross-sectional inquiry. Totally 510 patients referring to the infectious disease clinic of Imam Khomeini Hospital in Tehran from March 2020 to May 2020 were recruited. The inclusion criterion was suspected patients for COVID-19 based on clinical findings and CT scans of the lung. The infected patients included both inpatients (171) and outpatients (339). Demographic information, clinical signs, and the supplement pattern use were collected through a questionnaire and the data were statistically analyzed. Results: Vitamin D3 intake was reported in 30% (103 patients) of outpatients and 16.5% (28 patients) of hospitalized patients, which is statistically significant (P=0.001). It shows that, the frequency of vitamin D3 consumption in the outpatient group was higher than inpatient group. This significant difference has also been shown in zinc consumption, in 29 patients (9%) outpatients versus 4 patients (2%) inpatients were reported (P=0.007). Multi nominal regression showed that vitamin D3 intake has a supportive effect and reduces the risk of exacerbation and worsening of the disease. (OR=0.291; 95% CI 0.102-.0834, P=0.022). Conclusion: According to the results of the present study and the findings of other studies, considering the supportive effect of vitamin D3 in reducing the severity of infectious diseases; Clinical trials with an appropriate sample size are recommended to investigate the functional role of this vitamin in improving viral diseases of the respiratory tract.

Context Iodine, an essential constituent of thyroid hormones, is required for proper growth and development. Objective To investigate whether growth parameters at birth are associated with maternal urinary iodine concentration (UIC) or normal ranges of thyroid hormones during pregnancy. Data Sources Using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, electronic databases (namely, MEDLINE, Web of Science, the Cochrane Library, Scopus, and Google Scholar) were searched between January 1988 and November 2018 to identify relevant articles. Data Extraction Data from the studies included were independently extracted by 2 investigators using standardized forms developed for this review. Data Analysis The pooled mean birth weight, length, and head circumference values, and 95% confidence intervals were estimated in newborns born to women with UIC < 150 and UIC ≥150 μg/L during pregnancy. Possible linear or nonlinear associations between maternal UIC and the aforementioned anthropometric measures were evaluated. A narrative synthesis of the data was performed for thyroid hormones with levels within the normal range. Results Of the 123 studies identified, 11 were eligible for inclusion in the meta-analysis. The pooled mean birth weight, length, and head circumference in newborns whose mothers had UIC < 150 μg/L vs UIC ≥150 μg/L were 2898 g vs 2900 g (P = 0.970), 49.6 cm vs 49.4 cm (P = 0.880), and 34.0 cm vs 34.1 cm (P = 0.933), respectively. Dose-response meta-analyses revealed no significant linear or nonlinear associations between maternal UIC during pregnancy and anthropometric measures at birth. Among the different thyroid function parameters evaluated, high-normal values of maternal free thyroxine and thyrotropin during pregnancy were inversely associated with neonatal birth weight. Conclusion This systematic review showed that birth weight may be affected by even mild variations in the normal concentrations of maternal thyroid hormones. However, in the current meta-analysis, birth anthropometric measures were not associated with maternal UIC during pregnancy. [ABSTRACT FROM AUTHOR]

Introduction: Sexual dysfunction is a complex problem in postmenopausal women with a prevalence rate of 68%-86%. This study aimed to evaluate the effect of a fractional CO2 laser or vaginal cream on the improvement of sexual function in menopausal women. Methods: This is a two-group clinical trial study. Postmenopausal women with the inclusion criterion were enrolled and randomly divided into 2 groups of intervention (n = 25) and control group (n = 25). In the intervention group, CO2 laser therapy was performed every month for three months, and in the control group, Premarin vaginal cream was applied (0.625 mg, 3 nights a week for 3 months. Vaginal health index (VHI) scoring and Female Sexual Function Index (FSFI) questionnaires were completed before and three months after the treatment. Results: The effects of the laser treatment were greater than the Premarin group with respect to improvement in sexual desire, orgasms, sexual satisfaction, less pain during sexual relations, and overall sexual function (P < 0.05). Conclusion: It seems that the fractional CO2 laser may be more effective than hormonal therapy in improving sexual function in postmenopausal women. [ABSTRACT FROM AUTHOR]

Background: Literature to date has been inconclusive regarding the value of thyroglobulin (Tg) as a marker of iodine status in pregnant women. This systematic review and meta-analysis is one of the first to assess whether Tg concentration accurately reflects iodine status among pregnant women. Methods: We searched MEDLINE, the Web of Science, the Cochrane Library, Scopus, and other relevant databases to identify relevant studies published in the English language, between January 1988 and December 2018. The criteria for study inclusion in the systematic review were human studies, healthy pregnant women as participants, and available data for maternal urinary iodine concentration (UIC) and Tg level. Each study was assessed for quality and risk of bias. The pooled mean Tg values, and 95% confidence intervals were estimated in a population of women with UIC <150 and UIC ≥150 μg/L during pregnancy. Potential linear or nonlinear dose–response associations between maternal UIC and Tg concentration were examined. Results: Of 814 identified studies, 25 were eligible for inclusion in the meta-analysis. Studies included were conducted in Africa, Asia, Europe, South America, and the Oceania. The pooled mean (95% confidence interval [CI]) Tg concentration in iodine-deficient pregnant women was higher than that in iodine-sufficient pregnant women (10.73 μg/L [5.65–15.82] vs. 7.34 μg/L [2.20–12.47]); a comparison of the 95% CI showed that none of these values was significantly different. No significant differences were observed in Tg concentration between the two groups in each trimester of pregnancy. Dose–response meta-analyses revealed a significant nonlinear association between maternal UIC and Tg concentration during pregnancy. Among populations of pregnant women, an inverse association was found between UIC values <100 μg/L and Tg concentration (p-linearity = 0.007; p-nonlinearity = 0.027); however, higher values of UIC were not associated with Tg concentration. Conclusions: Our meta-analysis showed that Tg concentration can be a sensitive indicator of iodine deficiency, specifically in populations of pregnant women with median UIC <100 μg/L. Further studies are warranted to determine the sensitivity of Tg at different degrees of iodine deficiency during pregnancy. [ABSTRACT FROM AUTHOR]
