A three-dimensional lattice-free agent-based model of intracellular ice formation and propagation and intercellular mechanics in liver tissues.

A successful cryopreservation of tissues and organs is crucial for medical procedures and drug development acceleration. However, there are only a few instances of successful tissue cryopreservation. One of the main obstacles to successful cryopreservation is intracellular ice damage. Understanding how ice spreads can accelerate protocol development and enable model-based decision-making. Previous models of intracellular ice formation in individual cells have been extended to one-cell-wide arrays to establish the theory of intercellular ice propagation in tissues. The current lattice-based ice propagation models do not account for intercellular forces resulting from cell solidification, which could lead to mechanical disruption of tissue structures during freezing. Moreover, these models have not been expanded to include more realistic tissue architectures. In this article, we discuss the development and validation of a stochastic model for the formation and propagation of ice in small tissues using lattice-free agent-based model. We have improved the existing model by incorporating the mechanical effects of water crystallization within cells. Using information from previous research, we have also created a new model that accounts for ice growth in tissue slabs, spheroids and hepatocyte discs. Our model demonstrates that individual cell freezing can have mechanical consequences and is consistent with earlier findings.

Prevalence and Risk Factors of Prenatal and Postnatal Depressive Symptoms in Babol Pregnancy Mental Health Registry: A Cross-Sectional Study.

BACKGROUND: Prenatal and postnatal depression (PND) is associated with adverse outcomes for mother, fetus, and child. The aim of study was to examine the prevalence and risk factors of prenatal and postnatal depressive symptoms. MATERIALS AND METHODS: This was a cross-sectional and hospital-based survey of 2305 pregnant women and post-partum women (18-48 years) that was registered in the Babol Pregnancy Mental Health Registry (BPMHR) database from June 2020 to March 2021. Two questionnaires, including demographics and depression, were analyzed in this study. Also, the Edinburg Postnatal Depression Scale (EPDS) was used to assess the depressive symptoms. Independent t test and the analysis of variance were used to compare the means. Multiple logistic regressions were used to determine risk factors for depressive symptoms. RESULTS: According to the EPDS scale, the prevalence of depressive symptoms was 19.8% in the pregnant woman group in comparison with the postpartum period (11.6%). Risk factors for antenatal depressive symptoms were parity (women with parity ≥ 4 vs. 1 parity, ß=1.808, P=0.020), two groups of gestational age (gestational age ≤12 weeks vs. 28 weeks, ß=1.562 P=0.030) as well as (gestational age 21-27 weeks vs. 28 weeks (ß=1.586, P=0.033), and high-risk pregnancy (high-risk vs. low-risk pregnancy, ß=1.457, P=0.003). For postnatal depressive symptoms, none of the factors were a significant risk. CONCLUSION: Prenatal and postnatal depressive symptoms should be screened, particularly for women in the first and second trimesters, with high parity, and those with a high-risk pregnancy, as recommended by the present study.

Investigating the effect of levothyroxine replacement on cholesterol levels in hypothyroid patients.

Introduction: Effects of levothyroxine therapy on the lipid profile of hypothyroid patients lead to decrease in the risk of cardiovascular diseases and mortality. Objective: Overt or subclinical hypothyroid dysfunction has negative effects on lipid metabolism and leads to hypercholesterolemia that in turn increases the risk of cardiovascular diseases and mortality. In this matter, several interventional studies investigated the effects of levothyroxine therapy on the lipid profile of hypothyroid patients, and conflicting results have been obtained. The current research aims to investigate the effect of levothyroxine replacement on cholesterol levels in hypothyroid patients. Methods: The present prospective study examined 112 patients (mean age of 43.80 ± 14.36 years) with overt hypothyroidism. To do so, 72.3% of patients were females. Levothyroxine replacement therapy was prescribed for patients, and they were examined monthly to evaluate the effects of therapy on their lipid profiles. After reaching normal thyroid stimulating hormone (TSH), the patients' laboratory parameters, including TSH, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and triglycerides, were surveyed. Results: After Levothyroxine therapy, there was a significant reduction in mean TSH (62.03 vs. 2.33 ± 1.95; P < 0.0001), triglycerides (145.57 ± 88.65 vs. 121.91 ± 59.52, P = 0.002), cholesterol (203.90 ± 53.73 vs. 166.65 ± 40.07, P < 0.0001), and serum LDL (123.61 ± 45.03 vs. 95.99 ± 24.20, P < 0.0001), but the mean value of serum HDL did not show any significant change (54.18 ± 16.60 vs. 51.59 ± 18.38, P = 0.274). Conclusions: Levothyroxine therapy has beneficial effects on lipid profile in patients with overt hypothyroidism because it decreases serum triglyceride, total cholesterol, and LDL. However, levothyroxine therapy does not significantly change HDL levels.

Role of family communication patterns as predictors of behavioral health among students of public universities in north of Iran.

BACKGROUND: Communication is one of the oldest and greatest human achievements and the basis of social life. The aim of this study was to evaluate the role of family communication patterns as predictors of behavioral health among students of public universities in the north of Iran. MATERIALS AND METHODS: In this cross-sectional study, a total of 461 students from all the public universities of Babol, Iran, were selected in 2019. A stratified sampling random method was used to select the samples. The demographic characteristics, Depression Anxiety Stress Scale, Acceptance and Action Questionnaire, Rosenberg self-esteem questionnaire, and Communication Skills Interpersonal Test were used to collect data. Simple and multi-variate linear regressions as well as Pearson's correlation coefficient were utilized for data analysis. RESULTS: The mean and standard deviation scores of conversation orientation and conformity orientation were 35.61 ± 0.55 and 19.31 ± 0.41, respectively. Family conversation orientation was a significant predictor of behavioral health scales of students (except for acceptance and action), predicting negatively and significantly depression, anxiety, stress, and positively self-esteem and inter-personal communication skills of students. Family conformity orientation was also a significant predictor of behavioral health scales (except for inter-personal communication skills) of students, which predicted positively and significantly depression, anxiety, stress, and negatively acceptance, action, and students' self-esteem. CONCLUSION: To prevent behavioral health problems, it is necessary to observe conformity orientation and rely on conversation orientation.

Impact of primary care posttraumatic stress disorder (PC-PTSD) on fertility problem of Iranian women with infertility during the COVID-19 pandemic.

BACKGROUND: Infertility continued to be a major stressor among women with infertility during COVID-19pandemic. This study aimed to evaluate the impact of primary care posttraumatic stress disorder (PC-PTSD) on fertility problem of Iranian women with infertility during COVID-19 pandemic. METHOD: In this cross-sectional study, 386 women with infertility completed the questionnaires of PC-PTSD-5 and Fertility Problem Inventory (FPI) at an infertility center between 2020 and 2022. RESULTS: The mean of fertility problems was 145.20 (± 32.31). In terms of FPI subscales, the means were as follows: Sexual concern 21.80 (± 7.58), social concern 26.53 (± 8.94), relationship concern 26.02 (± 9.18), need for parenthood concern 40.88 (± 8.98), and rejection of childfree lifestyle 29.96 (± 7.69). The highest mean of FPI subscales was related to the need for parenthood concern in women with infertility. The strongest correlation was found between the subscales of sexual concern and social concern followed by sexual concern and relationship concern. The variables of PC-PTSD were a predictor of fertility problems (ß = 0.203, P < .0001). Additionally, the variables of PC-PTSDwere a predictor of sexual concern (ß = 0.248, P < .0001), social concern (ß = 0.237, P < .0001), relationship concern (ß = 0.143, P < .020), and need for parenthood concern (ß = 0.101, P < .010). After adjusting for demographic characteristics, there was a significant relationship between FPI with job (ß=-0.118, P < .031), education (ß=-0.130, P < .023), living place (ß = 0.115, P < .035), smoking (ß = 0.113, P < .036), relationship with husband (ß = 0.118, P < .027), and PC-PTSD symptom (ß = 0.158, P < .0001). In addition, the multivariate linear regression showed a significant association between sexual concern and education (ß=-0.152, P < .008), smoking (ß = 0.129, P < .018), PC-PTSD symptom (ß = 0.207, P < .0001); social concern and job (ß=-0.119, P < .033), PC-PTSD symptom (ß = 0.205, P < .0001); relationship concern and education (ß=-0.121, P < .033), living place (ß = 0.183, P < .001), relationship with husband (ß = 0.219, P < .0001); and rejection of childfree lifestyle and job (ß=-0.154, P < .007). CONCLUSION: Systematic PTSD screening during COVID-19 pandemic by healthcare providers can be uniquely used to identify, evaluate, and treat trauma-related health conditions in infertility settings, which can link women with infertility to mental health services. This can be novel and useful for future policymakers and practitioners in the infertility field.

Evaluation of the Cutoff Point and Diagnostic Value of the Neutrophil-to-Lymphocyte Ratio in Predicting Ovarian Cancer Compared to Pathological Findings.

PURPOSE: This research aims to establish a neutrophil-to-lymphocyte ratio (NLR) threshold and evaluate its diagnostic accuracy compared to pathological criteria for diagnosing Epithelial Ovarian Cancer (EOC). METHODS: We conducted a cross-sectional study at Imam Hossein Hospital involving 204 women aged 18 and older with confirmed ovarian mass based on pathology. We recorded clinical, pathological, and preoperative blood count data, including neutrophil-to-lymphocyte ratio (NLR). Patients were categorized into malignant and benign ovarian mass groups based on postoperative pathology. The power of NLR to diagnosis of EOC was evaluated using ROC curve. RESULTS: At total, 204 patients (Benign 75.5% vs. Malignant 24.5%) were included in the analysis with mean age of 54.26 ±12.04 yrs in malignant and 46.31±13.21 in benign. In all cases, the proportion of patients with the following tumor markers HE4 (>140 Pm), CA 125 (> 35U/Ml) and CEA (>5 ng/Ml) were 52.45%, 41.67% and 3.43%, respectively, and proportion of abnormal tumor markers was statistically higher in malignant group compared to benign mass (p <0.05).  Odds of having higher NLR levels in the malignancy group was higher than benign group (e.g., OR of 4.45 for NLR in quartile 4 vs. quartile 1).  According to model selection criteria, the full model with including NLR level and age, BMI and tumor markers has best performance for diagnosis of malignancy (AUC =0.87). CONCLUSION: High NLR in combination with tumor markers including CA125, HE4 and CEA were associated with malignancy in patients with ovarian mass. More attention and further examinations should be devoted for patients with ovarian mass having high NLR and abnormal tumor markers levels to detect the probable malignancy as soon as possible.

Effectiveness of computer-based stress inoculation training (SIT) counseling approach on anxiety, depression, and stress of students with premenstrual syndrome.

BACKGROUND: Premenstrual Syndrome (PMS) is a common public health issue affecting many women of reproductive age worldwide. This study has been designed to investigate of computer-based stress inoculation training (SIT) counseling approach on anxiety, depression, and stress of university students with PMS. METHODS: A randomized trial study with two parallel arms was done from 30 October 2022 to 21 June 2023 on 100 university students aged 18 to 38 at Babol University of Medical Sciences. The participants were randomly divided into two groups intervention and control. The data collection tools included questionnaires on demographic-fertility characteristics, the Premenstrual Symptoms Screening Tool (PSST), the Hospital Anxiety and Depression Scale (HADS), the Perceived Stress Scale (PSS-14), the Sheehan Disability Scale (SDS) and Riff's Psychological Well-being Scale (RPWS). The data were assessed using chi-square, t-student, ANOVA repeated measure, and linear regression tests. A significance level of P < 0.05 was considered for the analysis. RESULTS: The results of the study showed that the SIT interventions decreased the PMS severity and most psychological factors so in the intervention group, SIT was able to significantly reduce anxiety, depression, perceived stress, and Sheehan's disability after intervention (P < 0.001). Based on multiple linear regression analysis, the most predictors of HADS were the PSS and SDS (ß = 0.285, p = 0.009 and ß = 0.236, p = 0.024, respectively). CONCLUSION: The computer-based SIT counseling approach could reduce the severity of symptoms and psychological factors in students. Therefore, SIT intervention is recommended to manage their PMS.

Predictors of nonresponse to treatment and low adherence to internet-based cognitive behavioral therapy in depressed/anxious women facing the couple's fertility problems: a secondary analysis of a randomized control trial.

BACKGROUND: The study aimed to examine the predictors of treatment nonresponse and low adherence to Internet-based cognitive behavioral therapy and face-to-face therapy for treating depression and anxiety in women facing the couple's fertility problems. METHODS: This is a secondary analysis based on a previous randomized controlled trial including 152 depressed/anxious women facing the couple's fertility problems. The study defines low adherence as receiving less than 4 sessions (out of 8 sessions). Nonresponse to treatment refers to a < 50% reduction in the anxiety and depression total scores. RESULTS: A high level of anxiety/depression score before psychotherapy increases the risk of nonresponse to both Internet-based and face-to-face psychotherapies by 1.4 to 2 times in women facing the couple's fertility problems after the treatment and in the 6-month follow-up. However, 4 factors, including diagnosis of mixed anxiety and depression, low education level, long marriage duration, and infertility caused by mixed female/male factors, reduced the risk of nonresponse to psychotherapies. CONCLUSION: Women facing the couple's fertility problems with high depression and anxiety scores are at risk of poor prognosis in response to psychotherapy. Psychologists and healthcare providers of infertility centers should pay more attention to the timely identification and referral of depressed/anxious patients to psychologists.

Characteristics, outcome, duration of hospitalization, and cycle threshold of patients with COVID-19 referred to four hospitals in Babol City: a multicenter retrospective observational study on the fourth, fifth, and sixth waves.

BACKGROUND: The aim of the present study was to compare the epidemiological patterns of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) infections, hospitalizations, deaths, and duration of hospitalization during the fourth, fifth and sixth epidemic waves of coronavirus disease 2019 (COVID-19) in Iran. METHODS: A multicenter retrospective observational study was conducted on hospitalized patients in four hospitals in the Babol district of northern Iran. The study periods were during the fourth, fifth, and sixth waves of the epidemic in Iran, (March 2021 to March 2022). A total of 13,312 patients with suspected COVID-19 were included. Patient demographics, medical history, length of hospital stay, and clinical outcomes were obtained from the hospital information system. Data on the cycle threshold (Ct) and SARS-CoV2 variant were collected for SARS-CoV2-positive cases. RESULTS: The highest number of hospitalized patients was reported during the fifth (Delta) wave (5231; 39.3%), while the lowest number of hospitalized patients was reported during the sixth (Omicron) wave (2143; 16.1%). In total, 6459 (48.5%) out of 13,312 hospitalized patients with suspected COVID-19 had a positive rRT-PCR result. The fifth (Delta) wave had the highest number of SARS-CoV2 rRT-PCR-positive hospitalized patients (3573, 55.3%), while the sixth (Omicron) wave had the lowest number (835, 12.9%). Moreover, 238 (3.7%) patients with laboratory-confirmed COVID-19 died. The hospital mortality rate was 6.8% in the fourth (Alpha) wave, which reduced to 2.7 and 3.5% in the fifth (Delta) and sixth (Omicron) waves, respectively (p < 0.001). CONCLUSIONS: This is the most comprehensive study evaluating the epidemiologic characteristics of laboratory-confirmed SARS-CoV2 cases in Iran during the Alpha, Delta, and Omicron waves. The highest number of SARS-CoV2-positive hospitalized patients was in the fifth wave of COVID-19 (dominance of the Delta variant), while the sixth wave (dominance of the Omicron variant) had the lowest number. Comorbidities were similar, and cardiovascular disease, diabetes, kidney disease, and hypertension were the main risk factors in all waves.

Synthesis of colloidal silica nanofluid and assessment of its impact on interfacial tension (IFT) and wettability for enhanced oil recovery (EOR).

Ever-increasing global energy demand, from one hand and reduced oil initially in place in oil reservoirs due to production and reduced natural reservoir production capacity, on the other hand, has encouraged researchers to investigate different methods to improve and increase enhanced oil recovery (EOR) from oil reservoirs. One method is to employ nanotechnology in injected water, where nanoparticles could affect interfacial tension (IFT) between water and oil and wettability through properties, including high specific surface area and nanoparticle size. However, a major challenge in using nanoparticles in injected water is the instability of these particles in water, which ultimately reduces the efficiency of EOR. These particles cannot be stabilized through conventional methods at a large scale. In this study, stabilized silica nanoparticles were synthesized in the water phase using sodium silicate and sol-gel processes. The stability of this nanofluid was studied in seawater, and then its effect on IFT and changing wettability was examined. According to the results, seawater containing 40 times diluted nanofluid could obtain 41% reduced IFT and 40% alteration in wettability of carbonate core becoming more water-wet and ultimately 13.7% improved final oil recovery in secondary oil recovery and 8.3% improved final oil recovery in third EOR.

Influential factors for optimizing and strengthening mesenchymal stem cells and hematopoietic stem cells co-culture.

Mesenchymal stem cells (MSCs) and Hematopoietic stem cells (HSCs) are two types of bone marrow stem cells that can proliferate and differentiate into different cell lineages. HSCs interact with MSCs under protective conditions, called niche. Numerous studies have indicated supportive effects of MSCs on HSCs proliferation and differentiation. Furthermore, HSCs have many clinical applications and could treat different hematologic and non-hematologic diseases. For this purpose, there is a need to perform in vitro studies to optimize their expansion. Therefore, various methods including co-culture with MSCs are used to address the limitations of HSCs culture. Some parameters that might be effective for improving the MSC/ HSC co-culture systems. Manipulating culture condition to enhance MSC paracrine activity, scaffolds, hypoxia, culture medium additives, and the use of various MSC sources, have been examined in different studies. In this article, we investigated the potential factors for optimizing HSCs/ MSCs co-culture. It might be helpful to apply a suitable approach for providing high-quality HSCs and improving their therapeutic applications.

RGD-decorated nanoliposomes for combined delivery of arsenic trioxide and curcumin to prostate cancer cells.

Nanotechnology and drug co-delivery offer a novel avenue in drug delivery research liposome-based co-delivery of anticancer drugs targeting the apoptosis pathway as a promising new approach to treat cancer. In this study, a co-delivery system of liposomes (arsenic trioxide/curcumin) modified with RGD peptide was designed to aim for enhancing the treatment of prostate cancer cells (PC3 cell line). Liposomal co-loaded curcumin and arsenic trioxide modified by RGD peptide (NLPs-RGD-Cur-ATO) were prepared by thin-layer lipid hydration techniques for the treatment of prostate cancer. The stability of the NLPs-RGD-Cur-ATO was evaluated by particle size analysis through dynamic light scattering (DLS) analysis and transmission electron microscopy (TEM). The percentage of cytotoxicity and apoptotic effect in PC3 cells treated with NLPs-RGD-Cur-ATO were detected by MTT and Annexin V-FITC (fluorescein isothiocyanate)/PI affinity assay, respectively. The particle size of NLPs-RGD-Cur-ATO was approximately 100 nm, with an encapsulation efficiency of about 99.52% and 70.61%, for ATO and Cur, respectively. Besides, NLPs-RGD-Cur-ATO displayed an enhanced anti-proliferative effect, increased the percentage of apoptotic cells 98 ± 1.85% (p < 0.0001), and significantly reduced EGFR gene expression level (p < 0.001) in the cell line tested. These results indicated that our NLPs-RGD-Cur-ATO co-delivery system was a promising strategy for prostate cancer therapy.

Psychological distress in pregnancy and postpartum: a cross-sectional study of Babol pregnancy mental health registry.

BACKGROUND: Psychological distress (PD) is a significant issue during pregnancy and postpartum, adversely affecting both children and mothers. This study aims to determine PD's prevalence and risk factors in a large Iranian population sample during pregnancy and postpartum. METHODS: A cross-sectional study was conducted using data from the Babol Pregnancy Mental Health Registry (located in the north of Iran) between June 2020 and March 2021. A total of 2305 women were included, with 1639 during pregnancy and 666 during postpartum. Psychological distress was assessed using the Brief Symptoms Inventory (BSI-18), and data were analyzed using independent t-tests and multiple logistic regressions. RESULTS: The prevalence of psychological distress, defined by a cut-off score of BSI ≥ 13, was 19% during pregnancy and 15% during postpartum. Multivariate logistic analysis revealed that high-risk pregnancy was the leading risk factor for psychological distress during the antenatal period (ß = 1.776, P < 0.001), as well as its three subscales: somatization (ß = 1.355, P = 0.019), anxiety symptoms (ß = 2.249, P < 0.001), and depressive symptoms (ß = 1.381, P = 0.028). Additionally, women with a gestational age < 20 weeks had a higher risk of psychological distress (ß = 1.344, P = 0.038) and the somatization subscale (ß = 1.641, P < 0.001). During the postpartum period, women residing in urban areas were at higher risk of psychological distress (ß = 1.949, P = 0.012), as well as two subscales: anxiety symptoms (ß = 1.998, P = 0.012) and depressive symptoms (ß = 1.949, P = 0.020). CONCLUSION: The high prevalence of psychological distress emphasizes detecting and treating PD during pregnancy and postpartum, particularly in women with high-risk pregnancies. This study suggests that obstetricians and midwives should implement programs to identify women experiencing psychological distress during early pregnancy through postpartum visits.

Tracing air pollution changes (CO, NO2, SO2, and HCHO) using GEE and Sentinel 5P images in Ahvaz, Iran.

The first case of COVID-19 in Iran was reported on February 25, 2020, leading in the implementation of a government-mandated lockdown as the virus gradually spread to different cities. The objective of this study was to evaluate the impact of the COVID-19 pandemic on air quality in Ahvaz city by utilizing Sentinel 5 images and the Google Earth Engine (GEE) platform. Specifically, the concentrations of air pollutants, including CO, NO2, SO2, and HCHO, during the COVID-19 pandemic from May 10 to June 01, 2021, were examined. Also, they were compared to the same period in 2019. Additionally, the influence of meteorological parameters, such as wind speed and precipitation, on pollutant concentrations during the pandemic and in the pre-pandemic year of 2019 were investigated. The results revealed a significant decrease in the concentrations of NO2 (13.7%), CO (6.1%), SO2 (28%), and HCHO (9.5%) in Ahvaz during the study period in 2021 compared to the same period in 2019. Statistical analyses indicated no significant changes in wind speed and precipitation between the COVID-19 pandemic and the pre-pandemic period in 2019. Therefore, the impact of these parameters on the observed changes in pollutant concentrations can be disregarded. It is clear that the COVID-19 epidemic and the subsequent lockdown measures, including traffic restrictions and business closures, played a crucial role in significantly reducing air pollutant concentrations in Ahvaz.

Factors affecting students' attitudes towards reproductive health in the north of Iran: Designing an educational program.

BACKGROUND: It is essential to empower young people to promote reproductive health (RH) and develop effective educational programs to prevent risky behaviors. This study aimed to investigate the factors affecting students' attitudes towards RH based on the ecological model and then design an educational program. METHODS: This cross-sectional study was conducted on 461 female students aged 18-29 in the north of Iran. This study was done in two stages. In the first stage, factors affecting the attitude towards RH including demographic questionnaire, interpersonal communication skills, family communication pattern, depression, stress and anxiety, body self-image, and self-confidence were determined. In the second stage, an educational program was designed based on the most effective factors. Independent t-test, ANOVA, and multiple linear regression were employed using SPSS version 20 software. Also, STATA version 15 software was utilized for statistical modeling to predict the best predictive model of attitude towards RH. RESULTS: 47.7% of students had a good attitude toward RH. The majority of students had problems with interpersonal communication skills (60.7%). Also, 28.5% experienced depression, 35.8% anxiety, and 12.8% stress at different levels. More than a quarter of the students (26.5%) had poor body self-image and 18.7% had Undesirable self-esteem. Interpersonal skills (P = 0.002), family communication pattern (P = 0.004), stress (p = 0.019), anxiety (P = 0.001), and body self-image (P = 0.034) have a significant relationship with the attitude towards RH. The multiple regression showed that the most important effective factor on RH is the dialogue orientation of family communication pattern (P = 0.041), stress (P = 0.002), and anxiety (P = 0.001). CONCLUSION: Stress and anxiety management training and the use of dialogue orientation in the family communication pattern for young female students are recommended based on the scientific model.

Immunotoxicity induced by occupational inhalation exposure to waste anesthetic gases: a historical cohort study.

This study was undertaken to ascertain whether long-term occupational exposure to inhalational anesthetic, was associated with any significant alteration in the parameters of immune function. Materials and methods: This was a historical cohort study in which 30 male participants with at least one year of work experience in the operating room at the time of the study and 30 unexposed referent subjects were investigated. Exposure levels were quantified by measuring the urinary concentrations of nitrous oxide (N2O), isoflurane, and sevoflurane gases by headspace gas chromatography-mass spectrometry. Serum concentrations of interleukin-4 (IL-4), Th2-type cytokines, and interferon-gamma (IFN-γ) were measured by the ELISA method. Additionally, an automated hematology analyzer was used for the white blood cell count and white blood cell differential test. The data were analyzed using SPSS software for Windows version 21. Results: Mean urinary concentrations of N2O, isoflurane, and sevoflurane were found to be 211.57±75.15, 4.06±0.96, and 19.51±12.96  ppb, respectively. In simplistic statistical data analysis, significant differences were noted between exposed and control groups as far as the mean serum cytokines levels (IFN-γ, IL-4) were concerned. Furthermore, after adjusting for important confounders, statistical analysis showed that the IFN-γ, IL-4, and the ratio of IFN-γ/IL-4 were significantly higher in the exposed group than in the referent subjects. Conclusion: These findings provide corroborative evidence to further substantiate the contention that exposure to anesthetics agents (N2O, isoflurane, and sevoflurane) is associated with subtle, subclinical, prepathological changes in the parameters of immune function. The long-term ramification of these changes requires further investigation.

The prevalence of adjustment disorder and predisposing factors in infertile women.

BACKGROUND: Infertility is a stressful life event that increases the risk of developing mental disorders, particularly adjustment disorder (AD). Given the paucity of data on the prevalence of AD symptoms in infertility, the purpose of this study was to ascertain the prevalence, clinical presentation, and risk factors for AD symptoms in infertile women. METHOD: In a cross-sectional study, 386 infertile women completed questionnaires including the Adjustment Disorder New Module-20 (ADNM), the Fertility Problem Inventory (FPI), the Coronavirus Anxiety Scale (CAS), and the Primary Care Posttraumatic Stress Disorder (PC-PTSD-5) at an infertility center between September 2020 and January 2022. RESULT: The results indicated that 60.1% of infertile women exhibited AD symptoms (based on ADNM > 47.5). In terms of clinical presentation, impulsive behavior was more common. No significant relationship was observed between prevalence and women's age or duration of infertility. Infertility stress (ß = 0.27, p < 0.001), coronavirus anxiety (ß = 0.59, p = 0.13), and a history of unsuccessful assisted reproductive therapies (ß = 2.72, p = 0.008) were several predisposing factors for AD symptoms in infertile women. CONCLUSIONS: The findings suggest that all infertile women be screened from the start of infertility treatment. Additionally, the study suggests that infertility specialists should focus on combining medical and psychological treatments for individuals predisposed to AD, particularly infertile women who exhibit impulsive behaviors.

Comparing the effectiveness of virtual and semi-attendance Stress Inoculation Training [SIT] techniques in improving the symptoms of anxiety, depression, and stress of pregnant women with psychological distress: a multicenter randomized controlled trial.

BACKGROUND: Some studies indicate that more than 10% of pregnant women are affected by psychological problems. The current COVID-19 pandemic has increased mental health problems in more than half of pregnant women. The present study compared the effectiveness of virtual (VSIT) and semi-attendance Stress Inoculation Training (SIT) techniques on the improvement of the symptoms of anxiety, depression, and stress of pregnant women with psychological distress. METHODS: This study was conducted on 96 pregnant women with psychological distress in a 2-arm parallel-group, randomized control trial between November 2020 and January 2022. The semi-attendance SIT received treatment for six sessions, sessions 1, 3 and 5 as individual face-to-face and sessions 2, 4 and 6 as virtual once a week for 60 min continuously [n = 48], and the virtual SIT received six sessions simultaneously once a week for 60 min (n = 48) in pregnant women of 14-32 weeks' gestation referred to two selected hospitals. The primary outcome of this study was BSI-18 [Brief Symptom Inventory] and NuPDQ-17 [Prenatal Distress Questionnaire]. The secondary outcomes were the PSS-14 [Cohen's General Perceived Stress Scale]. Both groups completed questionnaires measuring anxiety, depression, pregnancy-specific stress, and generally perceived stress questionnaires before and after the treatment. RESULTS: The post-intervention results showed that the stress inoculation training technique in both VSIT and SIT interventions effectively reduced anxiety, depression, psychological distress, pregnancy-specific stress and general perceived stress [P < 0.01]. Also, the SIT interventions on decreasing anxiety [P < 0.001, η2 = 0.40], depression [P < 0.001, η2 = 0.52] and psychological distress [P < 0.001, η2 = 0.41] were more considerable than that of VSIT. However, There was no significant difference between SIT and VSIT intervention in terms of their effects on pregnancy-specific stress [P < 0.38, η2 = 0.01] and general stress [P < 0.42, η2 = 0.008]. CONCLUSION: The semi-attendance SIT group has been a more effective and practical model than the VSIT group, for reducing psychological distress. Therefore, semi-attendance SIT is recommended for pregnant women.

Depression and anxiety in adolescents and young women with polycystic ovary syndrome: a systematic review and meta-analysis.

OBJECTIVES: To evaluate the depression and anxiety symptoms, or both in adolescents and young women with polycystic ovary syndrome (PCOS) to those without PCOS. CONTENTS: A comprehensive electronic search was conducted to identify observational studies on PCOS patients (January 1991-December 2020). The population study included adolescents and young women (14-29 years of age) in two groups of cases (with PCOS) and controls (without PCOS) who were diagnosed with PCOS using the Rotterdam or National Institutes of Health criteria (NIH). Symptoms of depression, anxiety, or both, reported separately, were of interest. Mean (SD) of depression or anxiety symptoms, or both, as measured by a quantitatively validated scale for both the case and control groups. All eligible studies were quality assessed using the Newcastle-Ottawa Scale (NOS) tool. The initial database search resulted in the discovery of 1,582 papers, of which 806 were selected after screening the titles and abstracts and removing duplicates. A total of 49 papers were found to be suitable for full-text reading. This meta-analysis included ten studies comprising 941 adolescent/young women (391 with PCOS and 550 without PCOS). The standard mean difference (SMD) and its corresponding confidence interval (CI) at 95 % were used to compare depression or anxiety symptoms, or both, between two groups. SUMMARY AND OUTLOOK: The results, which included 192 cases, demonstrated that adolescents/young women with PCOS had significantly more depressive symptoms than those without PCOS (n=360) (SMD 0.72; 95 % CI, 0.09-1.34; Z=2.25, p=0.025; Heterogeneity: I2=89.7 %; p=0.000). Also, the results which included 299 cases demonstrated that adolescents/young women with PCOS had significantly more anxiety symptoms than those without PCOS (n=421) (SMD 0.59; 95 % CI, 0.13-1.05; Z=2.51, p=0.012; Heterogeneity: I2=86.1 %; p=0.000). This meta-analysis demonstrates that adolescent/young women with PCOS have significantly more depression or anxiety symptoms than those without PCOS.
