Anterior cruciate ligament-Return to sport after injury scale brief version after ACL reconstruction: Persian translation, cross-cultural adaptation and validation.

Purpose: The purpose of this study is to analyze the short anterior cruciate ligament return to sport after injury (ACL-RSI) (Persian) version's cultural adaption and validity. Methods: To assess test-retest reliability, 102 participants were filled out the short ACL-RSI(Per) scale 6 months or more after ACLR surgery. Internal consistency (Cronbach's alpha), test-retest reliability (intraclass correlation coefficients), construct validity (Pearson's r) and sensitivity (floor/ceiling effect) were determined. In addition, patient completed other relevant measures such as Lysholm scores, the hospital for special surgery ACL satisfaction survey (HSS ACL-SS), the visual analogue scale (VAS) of pain and patient's satisfaction, the Tegner activity score (TAS), the single assessment numeric evaluation (SANE) and the Cincinnati Knee Rating System (CKRS). Results: The short ACL-RSI(Per) scale showed high internal consistency (Cronbach's alpha = 0.91) and test-retest reliability (ICC = 0.923). Significant correlations between short ACL-RSI(Per) and other scales supported validity. There was a statistically significant connection between the short ACL-RSI(Per) and the following outcomes: HSS ACL-SS (r = 0.698, p < 0.001), VAS pain (r = 0.356, p < 0.001), CKRS (r = 0.644, p < 0.001), TAS (r = 0414, p < 0.001), Lysholm score (r = 0.467, p < 0.001) and SANE score (r = 0.536; p < 0.001). In addition to a satisfactory ceiling impact (15%), a sizeable floor effect (16.7%) was also seen. Conclusion: The short ACL-RSI(Per) scale is a reliable and valid tool for assessing psychological readiness for return to sport after ACL reconstruction in Persian. Level of Evidence: III.

Correlation of Sperm DNA Fragmentation Index With Semen Parameters, Lifestyle and Clinical Pregnancy Outcome After Intracytoplasmic Injection.

Objective: This study aimed to measure the correlation of sperm DNA fragmentation with semen parameters, lifestyle, and fertility outcomes after intracytoplasmic injection (ICSI). Materials and methods: The partners who were candidates for ICSI with a history of one In vitro fertilization (IVF) failure or male factor were recruited in the study. Semen parameters including sperm count, motility, and morphology as well as DNA fragmentation index (DFI) (that were divided into 2 groups as high (>15%), and low (≤15%) fragmentation scales) were evaluated either. The correlation of DFI with semen parameters, lifestyle, and clinical pregnancy after ICSI were compared between groups. Results: In 120 included couples, 59 men (49.2%) had DFIs ≤ 15% and 61 (50.8%) cases had DFIs >15%. In the group with higher DFI, abnormal morphology (p=0.010) was higher whereas, progressive motility (p=0.001), total motility (p<0.001), and total count (p<0.001) of sperm were significantly lower. In addition, the DFI was significantly higher in the subgroup of male infertility (0.012). Logistic regression showed that a lower risk of DFI>15% was associated with higher values of progressive motility (OR=0.97, p=0.001), total motility (OR=0.96, p=<0.001), count (OR=0.96, p=<0.001) and even clinical pregnancy (OR=0.27, p=0.011). However, a history of testicular surgery was associated with a higher risk of DFI>15% (OR=3.37, p=0.046). Although no correlation was found between male age and lifestyle components with DFI, the number of embryos was lower in DFI≥15% (p<0.001). Conclusion: DFI provide a clinically important measurement of sperm quality and have an impact on IVF outcomes; however, lifestyle components may not correlate with DFI.

Effect of Ondansetron on Postoperative Pain and Vomiting after Acute Appendicitis Surgery: A Placebo-Controlled Double-Blinded Randomized Clinical Trial.

Background: Common postoperative complications following surgery, particularly acute appendicitis surgery, include postoperative pain and vomiting, which can cause discomfort and delay recovery time. Methods: A randomized double-blinded placebo-controlled clinical trial was conducted with 80 cases of acute appendicitis of American Society of Anesthesiologists (ASA) physical status I or II and aged 18-60 y/o scheduled for appendectomy under general anesthesia. Patients were randomly divided into two equal groups: group A received 4 mg of ondansetron IV (2 ml) and group B received 2 ml of normal slain IV (placebo). Pain according to VAS, nausea and vomiting according to clinical symptoms, shivering and sedation according to the Bedside Shivering Assessment Scale (BSAS), and the Ramsay Sedation Scale (RSS) at 2, 6, 12, and 24 hours after surgery were evaluated and compared between the groups. Results: There was a significant decline in the severity of pain only at 2 hours after surgery between the ondansetron and control groups (5.3 ± 1.0 vs. 6.0 ± 1.0; p=0.01), not showing a difference between the groups at 6, 12, and 24 hours after appendectomy. Postoperative nausea and vomiting at 2 (5% vs. 25%; p=0.03) and 6 (7.5% vs. 27.5%; p=0.04) hours after appendectomy in the ondansetron group. At different times, the ondansetron and control groups did not differ in terms of pethidine consumption or sedation. Conclusions: In conclusion, our study found that ondansetron was effective in reducing postoperative vomiting after acute appendicitis surgery. However, it did not show a clinically significant effect on postoperative pain. This trial is registered with IRCT20230722058883N1.

Translation, cross-cultural adaptation, and validation of the Persian version of the Hospital for Special Surgery Anterior Cruciate Ligament Postoperative Satisfaction Survey.

PURPOSE: With over 140 million speakers spread across Iran, Afghanistan, and Tajikistan, Persian, also known as Farsi, is a pluri-centric language. The purpose of this study is to perform cross-cultural adaptation and examine the validity and reliability of the Persian translation of the Hospital for Special Surgery Anterior Cruciate Ligament Post-Operative Satisfaction Survey (HSS ACL-SS). METHODS: In this retrospective study, 102 anterior cruciate ligament reconstruction (ACLR) patients were asked to complete the Persian version of the HSS ACL-SS, Tegner scale, Lysholm score, the Single Assessment Numeric Evaluation (SANE) score, the Cincinnati Knee Rating System (CKRS), and the Visual Analogue Scale (VAS) for pain. Internal consistency was calculated via Cronbach's alpha coefficient. Validity was assessed with the correlations of Spearman's rho. 18 patients were included in the test-retest reliability assessment. The floor and ceiling effects of the examined content validity of HSS ACL-SS. RESULTS: The Cronbach's alpha coefficient was computed at 0.959, showing outstanding internal consistency. The intra-class correlation coefficient (ICC) demonstrated excellent results (0.986, P-value < 0.001). Insignificant ceiling effects (2.9%) and floor effects (3.9%) were detected. The Persian version of the HSS ACL-SS score significantly correlated with the SANE (r = 0.730, p < 0.001), Lysholm score (r = 0.622, p < 0.001), and CKRS (r = 0.741, p < 0.001). CONCLUSION: The overall performance of the Persian HSS ACL-SS was more than excellent in terms of reliability and validity. To conclude, Persian HSS ACL-SS may be used to assist patients in having a better perception of post-operative satisfaction.

Comparative analysis of neonatal umbilical cord blood gases across various delivery modes at a referral center.

BACKGROUND: This study aimed to address the increasing prevalence of cesarean section and the importance of evaluating newborn health through arterial blood gas analysis. Its primary objective was to compare the umbilical cord blood gas levels in newborns delivered through different delivery methods. METHOD: This retrospective descriptive cross-sectional study included singleton pregnancies with a gestational age between 37 and 42 weeks and infants weighing between 2500 and 4000 g. Newborns with an Apgar score of 7 or higher at 1 and 5 min were included. Umbilical cord blood samples were collected from each newborn for blood gas analysis within 60 min after birth. RESULT: The study included 340 neonates, with 170 born via caesarean section and 170 born through vaginal delivery. No significant differences were observed in Apgar scores between two groups. ABG analysis showed that vaginally born neonates had lower pH (7.24 ± 0.08 vs. 7.27 ± 0.07, P < 0.001), PCO2 (P = 0.015), and HCO3 (P < 0.001). Cesarean section neonates had higher oxygen saturation (P = 0.007) and pressure of oxygen (P < 0.001), and less negative base excess (P < 0.001). In the subgroup analysis, neonates whose mothers received epidural anesthesia had lower pH (7.23 ± 0.07 vs. 7.25 ± 0.08, P = 0.021) and more negative base excess (P = 0.026). Other parameters of ABG did not differ significantly between the groups (P > 0.05). CONCLUSION: It has been proven that the mode of delivery, whether it is vaginal or cesarean, as well as the administration of epidural anesthesia during vaginal delivery, have a significant impact on newborns at birth. Newborns delivered vaginally exhibit metabolic acidosis compared to those delivered via cesarean section. Although these differences are statistically significant, they do not have a notable clinical significance, as the average values of the evaluated parameters in both groups fall within the normal range.

Association of oxytocin augmentation with postpartum hemorrhage: a systematic review and meta-analysis.

OBJECTIVE: The current study aims to evaluate the correlation between oxytocin augmentation and postpartum hemorrhage. METHOD: PubMed, Web of Science, and Scopus has been searched for studies assessing the correlation between oxytocin augmentation and postpartum hemorrhage up to January 24, 2024. The search strategy included relevant keywords related to PPH and oxytocin augmentation. The risk of bias assessment was conducted by two reviewers using the Newcastle-Ottawa Scale (NOS). To pool the effects sized of included studies odds ratios (OR) of interest outcome with their 95% confidence interval (CI) were used. RESULTS: Eight studies were included in this meta-analysis. The pooled analysis of the included studies showed a statistically significant association between oxytocin augmentation and increased odds of PPH (pooled odds ratio [OR] = 1.27, 95% confidence interval [CI]: 1.05-1.53; I2 = 84.94%; p = 0.01). Publication bias was assessed using funnel plots, which appeared relatively asymmetrical, indicating significant publication bias. Galbraith plot and trim and fill plot were used for publication bias. Sensitivity analyses were performed by leave one out method. CONCLUSION: This meta-analysis suggests that using oxytocin for labor augmentation is linked to a significant increase in the risk of PPH. It highlights the need for careful monitoring and consideration when using oxytocin, especially in low and middle-income countries where guidelines and supervision are crucial.

The association between increased fetal movements in the third trimester and perinatal outcomes; a systematic review and meta-analysis.

BACKGROUND: Fetal movement monitoring is one of the strategies used to assess the fetus's health. Until now, most studies focused on the decreased fetal movement and neonatal outcome, although this systematic review and meta-analysis is designed to assess the association between increased fetal movements (IFM) with perinatal outcomes. METHOD: The electronic databases including PubMed, Scopus, Web of Science, and EMBASE were systematically searched for studies investigating the perinatal outcome of women with increased fetal movements from inception to July 2023. Following that, a random-effect meta-analysis model was used to obtain the combined diagnostic and predictive parameters including perinatal mortality (still birth and early neonatal mortality), operative delivery, Apgar score, neonatal resuscitation at birth and NICU Admission. RESULTS: After the initial screening, seven studies examining the association between increased third trimester fetal movement and various perinatal outcomes were included. Meta-analysis revealed a significant reduction in the risk of cesarean delivery among patients with IFM compared to controls, suggesting a potential protective effect during childbirth. However, no statistically significant difference was observed in birth weight, small or large for gestational age births, neonatal intensive care unit admission, maternal age, umbilical cord around the neck, gestational diabetes mellitus, and hypertension, indicating that IFM may not be a major predictor of adverse perinatal outcomes or maternal conditions. Notably, IFM was significantly associated with a higher likelihood of labor induction. CONCLUSION: The findings suggest that IFM may have a protective effect against cesarean delivery. Additionally, IFM does not appear to be significantly associated with maternal age, umbilical cord around the neck, gestational diabetes mellitus and hypertension. However, the observed significant association with labor induction warrants further investigation.

Conservative management of placenta previa-percreta with bladder invasion: A case report.

Key Clinical Message: Placenta previa, accompanied by placenta percreta, which involves invasion of the bladder, presents a significant risk of excessive bleeding during and after delivery. This case highlights that prophylactic embolization, conservative surgery, and careful monitoring offer an effective approach to avoid hysterectomy in cases of placenta percreta with adjacent organ involvement. Abstract: Placenta previa complicated by placenta percreta is associated with a high risk of massive intra and post-partum hemorrhage. We present a case of a 35-year-old woman (G2 P1) who was referred to the Akbar-Abadi hospital at 13 weeks of gestation. Color Doppler ultrasound indicated complete placenta previa-percreta with bladder invasion. After induction of fetal demise, bilateral uterine and bladder artery endovascular embolization was conducted for the patient. After 48 h, under ultrasound guidance, surgical resection of residual percreta tissue was conducted as much as possible. Eight weeks later, a follow-up sonography showed the minimum residual placenta tissue and she regained menstrual cycles after 2 months. This case indicated that the combination of prophylactic embolization, conservative surgical management with placenta left in situ, and follow-up with serial color Doppler monitoring, is an optimum method to avoid hysterectomy in placenta percreta patient with adjacent organ invasion.

Unexpected positive culture (UPC) in adults revision spine surgery: a systematic review and meta-analysis of incidence, risk factors, and management.

BACKGROUND: Without clear signs of infection, spinal implant failure is attributed to mechanical overloads and aseptic loosening. However, how low-grade infections contribute to seemingly aseptic implant failure is unclear. PURPOSE: The systematic review examined unexpected positive cultures (UPCs) in revision spine surgery regarding prevalence, isolated pathogens, risk factors, and strategies to reduce infection among asymptomatic patients undergoing revision spine surgery. METHODS: We followed the PRISMA guidelines and searched four main databases (PubMed, EMBASE, SCOPUS, Web of Science) comprehensively until January 2023 for articles reporting UPC after presumed aseptic adult revision spine surgery. The UPC rates were pooled, and risk factors were compared with the culture-negative control group and represented as odds ratio (OR) or mean difference (MD). RESULTS: Fifteen studies of 1057 individuals were included in two groups: culture-positive or UPCs (n = 317) and culture-negative or control (n = 740). The overall UPC prevalence was 33.2% (317/1057, range: 0 to 53%, 95% CI = 30.2%-36.4%), and Cutibacterium acnes (43.0%, 95% CI = 37.4%-48.8%), Coagulase-negative Staphylococci (CoNS), (39.5%, 95% CI = 33.2%-46.2%), and Staphylococcus species in general (49.5%, 95%CI = 43.7%-55.4%) were reported the most common isolated microbes. 16.1% of the UPCs were polymicrobial. Risk factors associated with UPC rates were female sex (OR = 2.62, 95%CI = 1.76-3.90, P < 0.001), screw loosening (OR = 4.43, 95%CI = 1.31-15.02, P = 0.02), number of operated levels (MD = 0.77, 95%CI = 0.33-1.22, P = 0.0007), and shorter time since index surgery (MD = - 8.57 months, 95%CI = - 14.76, -2.39, P = 0.02). CONCLUSIONS: One-third of patients undergoing spine revision surgery revealed UPC in this study. Each UPC pathogen interpretation and antibiotic use decision should be interpreted case by case. LEVEL OF EVIDENCE: IV.

A Decade of Lawsuits Against Surgeons Performing Female Genital Cosmetic Surgery (FGCS) in Tehran, Iran.

BACKGROUND: The objective of this study is to evaluate the legal proceedings that arise from Female Genital Cosmetic Surgeries (FGCS) and analyze the reasons why women file complaints against their surgeons. Additionally, we examined the outcomes of the legal decisions associated with these complaints. METHODS: This descriptive cross-sectional study was conducted in Tehran province, Iran, from 2012 to 2021. The primary data source for this study was forensic medical records, which were reviewed to gather relevant information. The collected data included the characteristics of the participants, the reasons for lawsuits, the procedure setting, and the outcomes of the legal decisions. RESULTS: A total of 121 patients were examined in the study, revealing that Labiaplasty was the most prevalent procedure (49.6%), followed by vaginoplasty (19.8%) and perineoplasty (13.2%). The most common complaints were related to cosmetic concerns (57%), lack of recovery (26.4%), and sexual dysfunctions (22.3%). Healthcare providers were found liable for malpractice in 52.1% of cases. Additionally, having the surgery performed by a gynecologist decreased the risk of malpractice (ß = 0.21, p= 0.034), while procedures in private clinics increased the risk (ß = 2.95, p = 0.040). CONCLUSION: The study's findings emphasized the importance of providing women with comprehensive education and consultations to ensure they are well-informed about the potential outcomes and risks of FGCS. Furthermore, the study highlighted the significance of having these surgical procedures performed by skilled and experienced surgeons.

Diagnostic value of neutrophil-to-lymphocyte and platelet-to-lymphocyte ratio to predict recurrent pregnancy loss and abortion; a systematic review and meta-analysis.

OBJECTIVE: This systematic review and meta-analysis aimed to evaluate the diagnostic value of the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) in women with a history of abortion (missed and threatened) and recurrent pregnancy loss (RPL) in comparison with healthy pregnancies. METHODS: Electronic databases including MEDLINE, Scopus, Web of Science, Embase, and Cochrane Library were searched for NLR and PLR in women who experienced early pregnancy loss up to January 1, 2023 with a combination of proper keywords. Meta-analysis was done for comparison with three or more studies and summary estimates were measured. RESULTS: A total of 390 citations were retrieved initially, and after screening, 16 articles were deemed eligible for the final review. Among these, 14 studies underwent meta-analysis. The meta-analysis revealed that the standard mean of the NLR was significantly higher in abortion cases compared to the control group. However, there was no significant difference in the PLR between the pregnancy loss group and the control group. CONCLUSION: NLR was significantly higher among RPL patients compared to the control group, according to these data, NLR may be capable of being used in the diagnosis of RPL as an easy, cheap, and accessible modality. Further studies, which take these variables into account, will need to be undertaken to determine the diagnostic value of NLR and PLR in early pregnancy loss.

Shoulder Arthroplasty After Previous Nonarthroplasty Surgery: A Systematic Review and Meta-Analysis of Clinical Outcomes and Complications.

BACKGROUND: Many patients who undergo shoulder arthroplasty (SA) have had at least 1 nonarthroplasty shoulder surgery before the surgery. There is conflicting evidence regarding the effects of previous shoulder surgery on the outcome of SA. A systematic review was conducted to compare functional outcomes and complications between SA patients with and without prior non-SA surgery on the ipsilateral shoulder. METHODS: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and searched MEDLINE/PubMed, Embase, Scopus, and Web of Science comprehensively from inception to January 2023. Based on 9,279 records reviewed, 26 comparative studies were included in the meta-analysis consisting of 5,431 shoulders with prior nonarthroplasty procedures (cases) and 55,144 shoulders without previous surgery (controls). Variables such as functional scores, complications, and range of motion were compared between cases and controls using Review Manager Software. In addition, subgroup analysis was conducted based on prior surgery type (rotator cuff repair [RCR], open reduction and internal fixation [ORIF], soft tissue repairs, and not specified) and type of SA (hemiarthroplasty, anatomical total shoulder arthroplasty, and reverse total shoulder arthroplasty [RTSA]). The results were presented as odds ratios (ORs) or standardized mean differences (SMDs). RESULTS: Except for a higher rate of periprosthetic joint infection (PJI) in patients who had undergone previous arthroscopic surgery (OR, 2.58; 95% confidence interval [CI], 1.66-4.01; p < 0.01), a higher rate of complications was only observed in patients with previous ORIF. These complications included aseptic loosening (OR, 3.43; 95% CI, 2.14-5.50; p < 0.01), shoulder dislocation (OR, 2.25; 95% CI, 1.05-4.84; p = 0.04), overall complication (OR, 3.95; 95% CI, 2.38-6.55; p < 0.01), and revision (OR, 2.52; 95% CI, 1.28-4.97; p = 0.01). Patients with a history of previous surgery demonstrated inferior functional outcomes in comparison with the control group, including American Shoulder and Elbow Surgeons (SMD, -0.39; 95% CI, -0.51 to -0.27; p < 0.01; I2 = 36%), Constant-Murley score (SMD, -0.34; 95% CI, -0.44 to -0.24; p < 0.01; I2 = 0%), abduction (SMD, -0.26; 95% CI, -0.45 to -0.08; p = 0.01; I2 = 54%), and flexion (SMD, -0.33; 95% CI, -0.46 to -0.21; p < 0.01; I2 = 40%). Subgroup analysis by previous type of surgery was not possible regarding functional outcomes. CONCLUSION: Patients who have had prior fracture surgery are at a higher risk of complications, reoperations, and revisions after SA than controls. The normal shoulder anatomy may be disrupted by prior surgery, which makes arthroplasty technically challenging, particularly when it comes to soft tissue balance. On the other hand, RCR before SA did not negatively affect clinical outcomes after RTSA and did not have a higher rate of overall complications (except PJI).

Examining the Morphology of External Genitalia in Iranian Women: A Labiagram-based Study in Iran and its Influence on Patients' Self-Satisfaction.

BACKGROUND: This study aims to document a woman's external genitalia data in the form of a labiogram and investigate whether variations in the size of specific components of a woman's external genitalia can influence her overall satisfaction with the esthetic appearance of her genitalia. METHODS: A cross-sectional observational study was carried out on a sample of 500 Iranian women. Socio-demographic information was collected for all participants, and they completed the Female Genital Self-Image Scale (FGSIS) questionnaire. Measurements of different external genitalia components were obtained for all participants. RESULTS: The findings revealed that there was no significant association between the measurements of the external genitalia and age or BMI. However, a significant negative correlation was observed between the total score on the FGSIS and specific parameters related to the width of different sections of the labia minora. The correlations were as follows: left lower third (r = - 0.305), lower right third (r = - 0.302), left middle third (r = - 0.365), right middle third (r = - 0.435), left upper third (r = - 0.397), and right upper third (r = - 0.407) (P value< 0.001). Moreover, cutoff points of 1.95 cm on the left side and 1.90 cm on the right side were identified through analysis as thresholds for predicting dissatisfaction among women. CONCLUSION: This study suggests that the width of the labia minora might influence certain women's motivation to undergo labiaplasty, a surgical procedure designed to modify the labia minora. To help women make informed decisions, it is crucial for those considering the procedure to have a comprehensive understanding of different labia minora types, potential benefits, and associated risks. By being well-informed, individuals can make choices that align with their personal preferences and priorities.

Does Using Highly Porous Tantalum in Revision Total Hip Arthroplasty Reduce the Rate of Periprosthetic Joint Infection? A Systematic Review and Meta-Analysis.

Background: Studies suggest tantalum (Ta) implants may have inherent antibacterial properties. However, there is no consensus regarding the effectiveness of Ta in preventing periprosthetic joint infection (PJI) after revision total hip arthroplasty (rTHA). Methods: We searched 5 main databases for articles reporting the rate of PJI following rTHA using Ta implants from inception to February 2022. The PJI rates of the Ta group were meta-analyzed, compared with the control group, and represented as relative risks (RRs) in forest plots. Results: We identified 67 eligible studies (28,414 joints) for assessing the prevalence of PJI following rTHA using Ta implants. Among these studies, only 9 compared the Ta implant group with a control group. The overall PJI rate following rTHA using Ta implants was 2.9% (95% confidence interval [CI]: 2.2%-3.8%), while it was 5.7% (95% CI = 4.1%-7.8%) if only septic revisions were considered. Comparing the Ta and control groups showed a significantly lower PJI rate following all-cause rTHA with an RR = 0.80 (95% CI = 0.65-0.98, P < .05). There was a trend toward lower reinfection rates in the Ta group after rTHA in septic cases, although the difference was not statistically significant (RR = 0.75, 95% CI = 0.44-1.29, P = .30). Conclusions: Ta implants are associated with a lower PJI rate following all-cause rTHA but not after septic causes. Despite positive results, the clinical significance of Ta still remains unclear since the PJI rate was only reduced by 20%. Level of Evidence: IV.

The effect of COVID-19 and COVID-19 vaccination on serum anti-Mullerian hormone: A systematic review and meta-analysis.

OBJECTIVE: The current study aims to evaluate the impact of COVID-19 infection and vaccination on ovarian reserve by detecting the anti-Mullerian hormone (AMH) level. METHOD: PubMed, Embase, Web of Science, and Scopus has been searched for studies assessing the effect of COVID-19 infection and/or vaccination on AMH levels up to February 27, 2023. Based on PRISMA 2020 statement criteria, a systematic review and meta-analysis of included studies were performed. The studies' quality was assessed by the National Institute of Health (NIH) quality assessment tool. The standardized mean difference (MD) of the AMH level was used and the quantitative values of each study were pooled separately by using a random effect model. RESULTS: Out of 246 studies screened, 18 were included in the systematic review and 14 in the meta-analysis. Included studies were published between 2021 and 2022 and were conducted in different countries, including the USA (n = 3), China (n = 2), Russia (n = 2), Turkey (n = 5), Israel (n = 3), Czech (n = 2), and Spain (n = 1). Eight studies investigated the effect of SARS-CoV-2 infection on AMH levels, and ten studies investigated the possible effect of COVID-19 vaccination on AMH levels. The pooled analysis showed a statistically significant decrease in AMH levels after COVID-19 infection (SMD: -0.24; 95% CI: -0.36 to -0.11; I2 = 0%; p = .0003). Vaccination analysis showed a nonstatistically significant change in AMH levels after COVID-19 vaccination (SMD: -0.11; 95% CI: -0.25 to 0.04; I2 = 35%; p = .14). CONCLUSION: COVID-19 infection can result in ovarian reserve injury by reducing the AMH level but getting vaccinated against COVID-19 has no impact on the AMH level.

Correlation between PAPP-A serum levels in the first trimester of pregnancy with the occurrence of gestational diabetes, a multicenter cohort study.

OBJECTIVE: This study aimed to investigate the association between first-trimester Pregnancy-associated plasma protein A (PAPP-A) levels and subsequent gestational diabetes mellitus (GDM) development. METHOD: The study was conducted on 5854 pregnant women who attended routine prenatal care. Maternal biomarkers, including PAPP-A and free beta hCG, were measured for all women in a referral laboratory and converted to MoM values. Pregnant women were divided into two groups, based on the serum concentration of PAPP-A, (PAPP-A > 0.4 (normal) and PAPP-A < 0.4 (low)). Data on the screening test for GDM and pregnancy outcomes were collected and analyzed with appropriate tests. RESULT: Of the 5854 pregnant women, 889 (15.19%) developed GDM. The maternal PAPP-A MoM concentrations were significantly lower in GDM cases compared to controls. Indeed, gestational age at delivery and birth weight were significantly lower (p < 0.001) in PAPP-A MoM < 0.4, and the rate of intrauterine growth restriction (IUGR) was significantly higher (p < 0.001). ROC analysis revealed that the sensitivity and specificity of MoM concentration for predicting GDM were 53.3% and 51.9%, respectively. CONCLUSION: Lower maternal PAPP-A in early pregnancy can lead to glucose intolerance and increase the risk of subsequent GDM development. In addition, decreased serum concentration of PAPP-A is significantly correlated to lower birth weight and IUGR.

Breastfeeding success and perceived social support in lactating women with a history of COVID 19 infection: a prospective cohort study.

BACKGROUND: Given the limited availability of research on the association between COVID-19 infection and breastfeeding success, the primary objective of this study is to conduct a comprehensive evaluation of this relationship. METHODS: This prospective cohort study included 260 women who were on the postnatal ward of an academic hospital affiliated with Tehran University of Medical Sciences during the COVID-19 pandemic (between March and August 2021). Among these women, 130 had tested positive for COVID-19 in pregnancy, while the remaining 130 were considered healthy. The study aimed to assess various factors, including sociodemographic characteristics and the results of four validated questionnaires: The Bristol Breastfeeding Questionnaire, The Multidimensional of Perceived Social Support (MPSS), The Breastfeeding Self-Efficacy Scale (BSES), and The Postpartum Partner Support Scale (PPSS). These questionnaires were administered to each participant to gather relevant data. After eight weeks, a telephone follow-up was carried out to assess the success of breastfeeding. The evaluation focused on determining if exclusive breastfeeding was maintained or not. Data was collected by questioning mothers about their infants' feeding habits in the past 24 h. Exclusive breastfeeding refers to the exclusive use of breast milk without the introduction of other liquids or solid foods. RESULTS: Women with a previous COVID-19 infection (case group) had a lower mean infant gestational age (P < 0.001) and a higher prevalence of cesarean section (P = 0.001) compared to the control group. The proportion of women who exclusively breastfed was higher in the control group (98.5%) than in women with a history of COVID-19 infection (89.2%) (P = 0.011). Furthermore, the case group reported lower scores in perceived social support and the Breastfeeding Self-Efficacy Scale, in contrast to the control group. Notably, there was a significant correlation between breastfeeding success and women's breastfeeding self-efficacy score. CONCLUSIONS: The findings of this study offer valuable insights for healthcare professionals, enabling them to promote early initiation of breastfeeding in mothers with a history of COVID-19 infection, while ensuring necessary precautions are taken.

Association between fetal liver diameter and glycemic control in pregnant women with gestational diabetes: A pilot study.

BACKGROUND: This study aimed to investigate the relationship between fetal liver length (FLL) and maternal glycemic status in pregnant women with gestational diabetes mellitus (GDM), as well as to determine whether FLL measurement in the third trimester is associated with neonatal outcomes. METHOD: A total of 51 singleton GDM pregnancies were included in this pilot study, and transabdominal ultrasound biometry and FLL measurements were performed between 34 and 36 weeks of gestation. Maternal indicators of glycemic control, including hemoglobin A1C (HbA1C), fasting blood sugar (FBS), and 2-h postprandial blood sugar were also evaluated during this period. The cases were followed up until delivery and maternal and neonatal outcomes were assessed to determine any correlation with FLL. RESULT: The results showed a significant positive correlation between FLL and HbA1C (r = 0.464, P = 0.001), FBS (r = 0.574, P < 0.001), 2-h postprandial blood sugar (r = 0.405, P = 0.002), and AC (r = 0.515, P < 0.001). Additionally, FLL was significantly associated with fetal birth weight (r = 0.408, P = 0.003) and birth weight (r = 0.460, P = 0.001). The FLL≥95th percentile group demonstrated a higher number of polyhydramnios (p = 0.007), macrosomia (p < 0.001), and maternal intensive care unit (ICU) admissions (p = 0.006). CONCLUSION: In conclusion, FLL measurement during third trimester of pregnancy is an indicator of maternal glycemic regulation and can be used as a predictor of macrosomia and neonatal birth weight in GDM pregnancies.
