Miliary Tuberculosis in In Vitro Fertilization pregnancy: a series of three cases with a history of hypothyroidism

In Vitro Fertilization (IVF) pregnancy is associated with a higher risk of tuberculosis as compared to normal pregnancy. This increased risk remains unexplained. Most of the reports are based on small case series, and the risk profile is not well described. Hypothyroidism has not been described as a potential risk factor in any series. In this case series, we elaborate on the profile of three military tuberculosis cases of IVF pregnancies, all having hypothyroidism history as the common factor, and were referred to our super-specialty center with the onset of symptoms during the late first or mid-second trimester of pregnancy. All three cases were diagnosed on X-ray chest Posterior-Anterior (PA) view, showing miliary tuberculosis and a known case of hypothyroidism. Antitubercular treatment was started. In this report, we describe the clinical course and unfavorable outcomes of these three cases.

Potential risk of gestational diabetes mellitus in females undergoing in vitro fertilization: a pilot study

BackgroundMost of the cases of hyperglycemia during pregnancy are attributed to gestational diabetes mellitus (GDM) (75–90%). Women diagnosed with GDM are at an increased risk for complications during pregnancy and delivery. This observational prospective study aimed to investigate the potential risk of GDM among Egyptian females following in vitro fertilization (IVF) pregnancies compared to spontaneous pregnancies (SC).MethodsThis prospective cohort study included normoglycemic females without any history of dysglycemia before this conception. Subjects were divided according to the type of conception into two age and BMI-matched groups: (IVF group): 55 pregnant females conceived by IVF, and (SC group) spontaneous pregnancy: 55 pregnant females conceived spontaneously. A one-step oral glucose tolerance test (OGTT) was performed at gestational weeks 20 and 28 for all study subjects.ResultsThe incidence of GDM was statistically significantly higher in the IVF group compared to the spontaneous pregnancy (SC) group (20 and 5.5%, respectively), p = 0.022 at week 28. On comparing the incidence of GDM on early screening at week 20 in both groups, the incidence of GDM in the IVF group was significantly higher (16.4%) compared to (3.6%) in the spontaneous pregnancy (SC) group, p = 0.026.ConclusionsIVF may have an increased potential risk for GDM. Moreover, the diagnosis of GDM may occur early (week 20), highlighting the need for precise and early screening for GDM in IVF pregnancies.

Assisted reproductive technology (ART) is not an independent risk factor for breech presentation among singleton term births in Vienna, Austria.

Assisted reproductive technologies (ARTs) such as in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) are still discussed critically, as there is no consensus on whether these treatments could be the cause of risk factors for obstetric problems such as breech presentation. The aim of this study was to test the association between ART and breech presentation among 11920 singleton term births taking place in Vienna from 2010 to 2020. In this single-centre medical record-based study, data concerning the conception mode (spontaneous versus IVF or ICSI), child presentation, birth mode, newborn sex and size as well as age, height, weight, and reproductive history of the mother were included. Three hundred twenty-six newborns (2.7%) were conceived by IVF or ICSI, and 527 newborns (4.4%) were delivered in breech presentation. Breech presentation occurred in 7.6% of IVF/ICSI children but only in 4.3% of spontaneously conceived children (P = 0.019). ART increased the crude risk of breech presentation significantly (OR = 1.67; 95% CI 1.71 - 2.38). After adjusting for maternal age, height, number of previous births, smoking, and newborn sex, however, ART had no longer a significant impact on the risk of breech presentation. In contrast, breech presentation was significantly associated with higher maternal age as well as a lower number of previous births, but not with ART. This study shows that the adverse outcomes of IVF and ICSI pregnancies may not be due to the ART treatment alone but might also be due to the mostly higher age and lower parity of the mothers using ART.

Obstetric and maternal outcomes of IVF and oocyte donation pregnancies among women ages 40-45-a large cohort study.

To analyze the perinatal and maternal outcomes of women ranging in age from 40 to 45 years who gave birth after in vitro fertilization or oocyte donation, compared to spontaneous conception. This retrospective cohort study used electronic data from a national healthcare service from 2000 through 2019. Three groups were compared: spontaneous pregnancy (SC), in vitro fertilization (IVF) utilizing autologous oocytes, and pregnancies resulting from oocyte donation (OD). The primary study outcomes were preterm labor (PTL) before 37 weeks of gestation, and infants classified as small for gestational age (SGA). The cohort included 26,379 SC, 2237 IVF pregnancies, and 300 OD pregnancies for women ages 40-45 years at delivery. Women with OD or IVF had a higher incidence of PTL < 37 weeks compared to women with SC (19.7% vs. 18% vs. 6.9%, p = 0.001), PTL < 34 (7% vs. 4.5% vs. 1.4%, p = 0.001), PTL < 32 (3.7 vs. 2.1 vs. 0.6, p = 0.001). A multivariable logistic regression for PTL < 37 weeks demonstrated that age (OR = 1.18) and hypertensive diseases (OR = 3.4) were statistically significant factors. The OD group had a lower rate of SGA compared to SC (1% vs. 4.3%, p = 0.001), while the IVF group had a higher rate of SGA compared to SC (9.1% vs. 4.3%, p = 0.001). Hypertensive diseases in pregnancy were significantly higher among the OD group and the IVF group compared to SP pregnancies (3.3% vs. 1%, p = 0.002; 2.3% vs. 1%, p = 0.001, respectively). Women ages 40-45 undergoing IVF or OD have a greater risk of PTL, possibly due to higher rates of hypertensive disorders of pregnancy.

Medical treatment for early pregnancy loss following in vitro fertilization compared to spontaneous pregnancies.

Misoprostol is a well-studied medical treatment for early pregnancy loss (EPL), with success rates ranging between 70 and 90%. However, treatment failure is associated with major patient discomfort, including the need for surgical intervention to evacuate the uterus. It was previously reported that medical treatment was especially successful among women who conceived after in vitro fertilization (IVF). We aimed to study if there is a difference in rates of medical treatment failures for EPL between pregnancies conceived by IVF and spontaneous pregnancies. In this retrospective cohort study, we included all women who underwent medical treatment for EPL at our institute between 07/2015 and 12/2020. Treatment outcome was compared between IVF and spontaneous pregnancies. Treatment failure was defined as a need for surgical intervention, namely, dilation & curettage (D&C) and/or hysteroscopy, due to retained products of conception, which was defined as a gestational sac or endometrial thickness greater than 15 mm in a TVS scan. Overall, 775 patients were included, of which 195 (169/775 = 25.1%) ultimately required surgical intervention. There was no difference between the study groups in the rate of treatment failure. However, among IVF pregnancies, the rate of emergency D&C was lower (3.6% vs. 9.8%, p = 0.001), compared to spontaneous group. In cases of medical treatment for EPL, IVF pregnancies had no differences in rates of treatment failure compared to spontaneous pregnancies. That being said, IVF pregnancies have lower chances to undergo emergency D&C, compared to spontaneous pregnancies.

Risk factors for early postpartum hemorrhage: A retrospective, population-based, cohort analysis.

To identify risk factors for developing early postpartum hemorrhage (PPH) and to examine whether risk factors vary according to severity and mode of delivery. A population-based cohort study was conducted in which all deliveries at a tertiary medical center were included. Risk factors for developing early PPH were compared based on the severity of bleeding as well as the mode of delivery. Multiple logistic regression models were used to control for confounders. Among 322 497 deliveries included in the analysis, early PPH complicated 1811 (0.56%) of all deliveries. Among all cases of early PPH, 505 deliveries (28%) were complicated with severe PPH. Using a logistic regression model, invitro fertilization (IVF) pregnancy, previous cesarean delivery (CD), pre-eclampsia, placental abruption, and uterine rupture were independently associated only with severe early PPH, while non-progressive second stage of labor, induction of labor, and large for gestational age were independently associated with both severe and mild early PPH. When applying an additional logistic regression model, whereas IVF pregnancy, pre-eclampsia, and large for gestational age were independently associated with early PPH among vaginal deliveries only, placenta previa was independently associated with early PPH among CD only. Independent risk factors for developing severe PPH solely include IVF pregnancy, previous CD, pre-eclampsia, placental abruption, and uterine rupture. IVF pregnancy, pre-eclampsia, and large for gestational age are independent risk factors for early PPH following vaginal delivery, while placenta previa is independently associated with early PPH after CD only. Due to the recognition of the importance of both the provider and institutional planning and preparation for PPH, the study's results should be viewed within the scope of its retrospective cohort design.

Development of a single-visit protocol for the management of pregnancy of unknown location following in vitro fertilization: a retrospective study.

Can women with pregnancy of unknown location (PUL) following in vitro fertilization (IVF) be risk-stratified regarding the subsequent need for medical intervention, based on their demographic characteristics and the results of serum biochemistry at the initial visit? The ratio of serum hCG to number of days from conception (hCG/C) or the initial serum hCG level at ≥5 weeks' gestation could be used to estimate the risk of women presenting with PUL following IVF and needing medical intervention during their follow-up. In women with uncertain conception dates presenting with PUL, a single serum hCG measurement cannot be used to predict the final pregnancy outcomes, thus, serial levels are mandatory to establish a correct diagnosis. Serum progesterone levels can help to risk-stratify women at their initial visit but are not accurate in those taking progesterone supplementation, such as women pregnant following IVF. This was a retrospective study carried out at two specialist early pregnancy assessment units between May 2008 and January 2021. A total of 224 women met the criteria for inclusion, but 14 women did not complete the follow-up and were excluded from the study. We selected women who had an IVF pregnancy and presented with PUL at ≥5 weeks' gestation. A total of 30/210 (14.0%, 95% CI 9.9-19.8) women initially diagnosed with PUL required surgical intervention. The hCG/C was significantly higher in the group of women requiring an intervention compared to those who did not (P = 0.003), with an odds ratio of 3.65 (95% CI 1.49-8.89, P = 0.004). A hCG/C <4.0 was associated with a 1.9% risk of intervention, which accounted for 25.7% of the study population. A similar result was obtained by substituting hCG/C <4.0 with an initial hCG level <100 IU/l, which was associated with 2.0% risk of intervention, and accounted for 23.8% of the study population (P > 0.05). A limitation of our study is that it is retrospective in nature, and as such, we were reliant on existing data. A previous study in women with PUL after spontaneous conception found that a 2% intervention rate was considered low enough to eliminate the need for close follow-up and serial blood tests. Using the same 2% cut-off, a quarter of women with PUL after IVF could also avoid attending for further visits and investigations. No external funding was required for this study. No conflicts of interest are required to be declared. N/A.

Pregnancies through oocyte donation. A mini review of pathways involved in placental dysfunction.

Pregnancies resulting from assisted reproductive techniques (ART) are increasingly prevalent worldwide. While most pregnancies conceived through in-vitro fertilization (IVF) progress without complications, mounting evidence suggests that these pregnancies are at a heightened risk of adverse perinatal outcomes. Specifically, IVF pregnancies involving oocyte donation have garnered attention due to numerous reports indicating an elevated risk profile for pregnancy-related complications within this subgroup of patients. The precise mechanisms contributing to this increased risk of complications remain incompletely understood. Nonetheless, it is likely that they are mediated by an abnormal immune response at the fetal-maternal interface. Additionally, these outcomes may be influenced by baseline patient characteristics, such as the etiology of infertility, absence of corpus luteum, and variations in endometrial preparation protocols, among other factors. This review aims to succinctly summarize the most widely accepted mechanisms that potentially contribute to the onset of placental dysfunction in pregnancies conceived through oocyte donation.

Severe Early-Onset Intrahepatic Cholestasis of Pregnancy Following Ovarian Hyperstimulation Syndrome with Pulmonary Presentation after In Vitro Fertilization: Case Report and Systematic Review of Case Reports.

Intrahepatic cholestasis of pregnancy (ICP) is the most common pregnancy-related liver disease, usually presented in the third trimester with pruritus, elevated transaminase, and serum total bile acids. Evidence shows that it can be developed in the first trimester, more commonly after in vitro fertilization (IVF) procedures, with the presence of ovarian hyperstimulation syndrome (OHSS). A literature search was conducted in the PubMed/MEDLINE database of case reports/studies reporting early-onset ICP in spontaneous and IVF pregnancies published until July 2023. Thirty articles on early-onset ICP were included in the review analysis, with 19 patients who developed ICP in spontaneous pregnancy and 15 patients who developed ICP in IVF pregnancies with or without OHSS. Cases of 1st and 2nd trimester ICP in terms of "early-onset" ICP were pooled to gather additional findings. Proper monitoring should be applied even before expected pregnancy and during IVF procedures in patients with known risk factors for OHSS and ICP development (patient and family history), with proper progesterone supplementation dosage and genetic testing in case of ICP recurrence.

Ten years of invitro fertilization in Indonesia: Access to infertility care in a developing country.

This research was conducted to assess access to assisted reproductive technologies (ART) and the current status of the invitro fertilization (IVF) program that have been implemented in Indonesia over the last 10 years. We established a retrospective cohort study and descriptive analysis of the current state of access to infertility care in Indonesia. The data were collected from all IVF centers, clinics, and hospitals in Indonesia from 2011 to 2020, including the number of IVF clinics, total ART cycles, retrieved fresh and frozen embryos, average age of IVF patients, IVF pregnancy rate, and causes of infertility. The number of reported fertility clinics in Indonesia has increased from 14 clinics in 2011 to 41 clinics by 2020. As many as 69 569 ART cycles were conducted over the past 10 years, of which 51 892 cycles used fresh embryos and 17 677 cycles used frozen embryos. The leading cause of consecutive infertility diagnosis was male infertility. Nearly half of the women who underwent IVF procedures (48.9%) were under 35 years old. The pregnancy rate outcome of women who underwent IVF ranged from 24.6% to 37.3%. Developments in ART in Indonesia have led to improvements in the ART cycles performed throughout the 10 year period. The identification of key areas that require improvement can provide an opportunity to enhance access to infertility care.

Comprehensive appraisal of pregnancy and neonatal outcomes in singleton pregnancies conceived via invitro fertilization in the USA (2016-2021).

We set out to compare adverse pregnancy and neonatal outcomes in singleton gestations conceived via invitro fertilization (IVF) to those conceived spontaneously. Retrospective, population-based cohort using the CDC Natality Live Birth database (2016-2021). All singleton births were stratified into two groups: those conceived via IVF, and those conceived spontaneously. The incidence of several adverse pregnancy and neonatal outcomes was compared between the two groups using Pearson's chi-square test with Bonferroni adjustments. Multivariate logistic regression was used to adjust outcomes for potential confounders. Singleton live births conceived by IVF comprised 0.86 % of the cohort (179,987 of 20,930,668). Baseline characteristics varied significantly between the groups. After adjusting for confounding variables, pregnancies conceived via IVF were associated with an increased risk of several adverse pregnancy and neonatal outcomes compared to those conceived spontaneously. The maternal adverse outcomes with the highest risk in IVF pregnancies included maternal transfusion, unplanned hysterectomy, and maternal intensive care unit admission. Increased rates of hypertensive disorder of pregnancy, preterm birth (delivery <37weeks of gestation), and cesarean delivery were also noted. The highest risk neonatal adverse outcomes associated with IVF included immediate and prolonged ventilation, neonatal seizures, and neonatal intensive care unit admissions, among others. Based on this large contemporary United States cohort, the risk of several adverse pregnancy and neonatal outcomes is increased in singleton pregnancies conceived via IVF compared to those conceived spontaneously. Obstetricians should be conscious of these associations while caring for and counseling pregnancies conceived via IVF.

25(OH)D3 improves granulosa cell proliferation and IVF pregnancy outcomes in patients with endometriosis by increasing G2M+S phase cells

BackgroundThe 25-hydroxyvitamin D3 (25 (OH) D3) is crucial for follicular development. This study aimed to investigate the relationship between the level of 25 (OH) D3 in endometriosis patients, pregnancy outcomes of in vitro fertilization (IVF), and the underlying mechanism.MethodsThe 25 (OH) D3 levels in serum and follicular Fluid (FF) samples were detected using enzyme-linked immunosorbent assay (ELISA). Clinical features and pregnancy outcomes of endometriosis patients were also compared between the deficient group (< 20 ug/ml) and the adequate group (≥ 20 ug/ml). The effects of 25 (OH) D3 on the proliferation and cell cycle of human ovarian granulosa cells were respectively detected by CCK-8 assay and flow cytometry (FCM). The differentially expressed genes (DEGs) in granulosa cells of endometriosis and tubal infertility patients were screened from GEO database. The effects of 25 (OH) D3 on the expressions of CDKN2D, PPARA, TGFB2 and THBD were determined using quantitative reverse transcription polymerase chain reaction (qRT-PCR) and Western blot.ResultsThe levels of 25 (OH) D3 in serum and FF samples were decreased in endometriosis patients. The deficient group had fewer embryos that can be transferred, lower quality embryos and lower clinical pregnancy rates. Adequate 25 (OH) D3 levels in FF samples was a protective factor for live birth outcome in endometriosis patients. 25 (OH) D3 enhanced the proliferation capacity of granulosa cells (the concentration of 10 nM was the most significant) and increased the proportion of G2M + S phase cells. The expression of CDKN2D was decreased and TGFB2 and THBD were significantly upregulated.Conclusions25 (OH) D3 deficiency may be associated with poor IVF pregnancy outcomes in endometriosis patients. 25 (OH) D3 promotes ovarian granulosa cell proliferation by promoting the ability of cells to divide, and may accelerate cell cycle progression by up-regulating THBD and down-regulating CDKN2D expression.

The multiple reference range of mean uterine artery pulsatility index for natural and in vitro fertilization singletons during 11-14 gestational weeks.

Ultrasonography of the uterine artery (UtA) in the first and second trimesters of pregnancy can assess uterine-placental blood perfusion and guide early clinical prevention. Establishing normal ranges of the UtA pulsatility index (UtA-PI) at 11-14 weeks of pregnancy is helpful for the early identification of high-risk pregnant women and improving the prognosis. This study aimed to establish a reference range of UtA-PI based on crown-rump length (CRL) for spontaneous and in vitro fertilization (IVF) singleton pregnancy during 11-14 weeks, respectively. A prospective study was performed at Peking Union Medical College Hospital. Healthy, low-risk women with a singleton pregnancy at 11-14 gestational weeks were consecutively recruited for this study from December 2017 to December 2020. All participants underwent routine prenatal ultrasound examination. The CRL of the fetus and the UtA-PI were measured in both uterine arteries, and average values were calculated. The LMS method was used to fit the percentile (P)5, P10, P25, P50, P75, P90, and P95 curves of the UtA-PI value of spontaneous and IVF singleton pregnancy with CRL changes, respectively. A total of 1,962 pregnant women with normal fetuses were included in this study, including 1,792 pregnancies conceived naturally and 170 IVF fetuses. The UtA-PI reference range in the spontaneous pregnancy group was consistently higher than that in the IVF group during 11-14 weeks, and showed a statistically significant difference in UtA-PI for spontaneous and IVF pregnancies (P<0.001). According to the LMS method, each percentile curve of UtA-PI decreased with the increase of CRL in both the natural pregnancy group and the IVF group. The P95 range of UtA-PI for pregnant women with naturally conceived and IVF pregnancy was 2.74 to 2.11 and 2.50 to 1.94, respectively. The overall change of UtA-PI differentials of the two groups showed a downward trend and decreased slightly with the increase of CRL. This study provided a single-center, large sample of data and constructed a CRL-based reference value of UtA-PI for spontaneous and IVF singleton pregnancy, which provides a reliable basis for early UtA evaluation and early clinical decision-making during 11-14 gestational weeks.

Antenatal fetal growth patterns in uncomplicated pregnancies according to mode of conception and placental location

Newborns resulting from in-vitro fertilisation (IVF) had a significantly (P= 0.002) higher birthweight centile than those resulting from spontaneous conception (SC) but no significant changes were found in ultrasound estimated fetal weight (EFW) centile between 20-22 and 32–34 weeks between the IVF and SC groups. When stratified for the IVF methods used, significant (P = 0.02) fastest in-utero fetal growth (mean increase in centile of 5 between 2nd to 3rd trimester) was observed in the frozen embryo transfer (FET) subgroup compared to SC, and to IVF pregnancies resulting from fresh blastocyst transfer (FBT) or from oocyte donation (OD). Low placentation was significantly (P < 0.001) more common in the IVF group than in the SC group but was not associated with a change in growth pattern suggesting that fetal growth in-utero is independent of placental location but may be influenced by embryo freezing.

In vitro fertilization pregnancy may cause fetal thymic volume involution: A case-control study

Background: The effect of modern infertility treatment modalities on fetal thymic volume has not been well known.&#x0D; Objective: 3-dimensional (3D) fetal thymus volumes of 18-24 wk in vitro fertilization (IVF) pregnancies and spontaneous pregnancy cases were compared.&#x0D; Materials and Methods: 135 cases were evaluated in this prospective case-control study. The study was conducted between July 2019 and July 2020 at a university hospital in Trabzon, Turkey. Fetal thymus volume was calculated in the pregnant cases included in the study with the help of the virtual organ computer-assisted analysis system included in the advanced ultrasonography system. The fetal thymus volumes were compared between pregnant women with IVF and spontaneous pregnant women.&#x0D; Results: The fetal thymus size was significantly lower in the IVF pregnancy group than in spontaneous pregnancy cases (p &lt; 0.001). It was found that the fetal complications, such as non-reassuring fetal health status and requirement for neonatal intensive care, were higher in cases who became pregnant after IVF treatment. It was also found that the rate of any pregnancy complication was significantly higher in IVF pregnancy c group (p = 0.02).&#x0D; Conclusion: In light of these results, it may be concluded that small fetal thymus size may be another fetal complication of IVF pregnancies.&#x0D; Key words: Fetus, Fertilization in vitro, Prenatal ultrasonography, Thymus.

Comparison between the modified long gonadotropin-releasing hormone agonist protocol and the non-downregulation protocol in POSEIDON groups: a propensity score matching retrospective cohort study.

In vitro fertilization (IVF) is the main technique to address the infertility issue in the patient-oriented strategy encompassing individualized oocyte number (POSEIDON) population. Adopting appropriate protocols for assisted reproduction technologies (ART) cycles in the POSEIDON group may attain more favorable pregnancy outcomes. This study aimed to compare the effectiveness of modified long gonadotropin-releasing hormone agonist protocol and non-downregulation protocol in POSEIDON patients undergoing ART, and to identify the factors affecting the pregnancy outcomes in this group. This study was designed as a propensity score-matched (PSM) retrospective analysis. The study cohort consisted of 910 patients diagnosed with ovarian hyporesponsiveness and treated by IVF from January 2020 to June 2022. They were followed up until the transfer of the last embryo of the IVF cycle and/or pregnancy at 12 weeks. The study was conducted at the Center of Reproductive Medicine, Tongji Medical College, Wuhan Union Hospital, Huazhong University of Science and Technology. The patients were divided into Group I and Group II. Group I was treated with modified long gonadotropin-releasing hormone agonist protocol while Group II was put on a non-downregulation protocol. Propensity score matching (PSM) was used to select patients for each group. The subjects were compared in terms of the baseline level, process of controlled ovarian hyperstimulation, and pregnancy outcomes. Binary logistic regression analysis was performed to assess the difference in the cumulative pregnancy rate between the two groups. Of the 910 POSEIDON patients who underwent IVF, 213 received the modified long gonadotropin-releasing hormone agonist protocol and 697 were subjected to the non-downregulation protocol. From the original cohort, PSM matched 174 pairs of patients. No statistically significant difference was found in total gonadotropin (Gn) dose between the two PSM groups, but the average daily Gn dose was lower in Group I and the duration of Gn lasted longer. The number of retrieved oocytes, the number of metaphase II (MII) ooctyes retrieved, normal fertilization, and normal cleavage embryos was significantly higher in Group I than in Group II, but there existed no significant difference in the number of high-quality embryos between the two groups. The single-cycle CPR (cumulative pregnancy rate) was higher in Group I than in Group II (for Group I: before PSM, CPR = 52.6%; after PSM, CPR = 51.7%; for Group II: before PSM, CPR = 34.0%; after PSM, CPR = 34.5%), and the difference was statistically significant. A binary logistic regression analysis in the unmatched patients showed that the CPR of Group II was 0.486 times that of Group I (95% CI: 0.303 to 0.779). The modified long gonadotropin-releasing hormone agonist protocol can be used as an optimal protocol for IVF or ICSI (Intracytoplasmic sperm injection) in POSEIDON patients. Level III.

The role of clinical and immunological factors in the outcomes of in vitro fertilization procedure in women

The objective: to determine the features of clinical and immunological factors in women undergoing in vitro fertilization (IVF) procedure and to determine a relationship between these parameters and the procedure outcomes.Materials and methods. In the period from 2020 to 2022, 131 patients were examined at the Reproductive Department of the Caspian International Hospital. Of these, 103 (78.6%) are aged 19-35 years, 28 (21.4%) are aged 36-50. Patients were grouped and analyzed based on: IVF success (presence or absence of fertilization), pregnancy (yes, no), and infertility factors. Markers of peripheral blood mononuclear cells (CD16/56 and HLA-DR) were determined in 50 women. The cytokines – interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and interferon-ɣ (IFN-ɣ) were studied in blood serum of 84 patients. All samples were taken at the day of oocyte pick-up. Descriptive statistical methods (mean, standard deviation, median, frequency, percentage, and minimum and maximum), Student-t test and Mann–Whitney U test (for comparisons between two groups) were used while evaluating the study data. Statistical significance was accepted as p&lt;0.05.Results. Female infertility occurred in 49 (37.4%) patients, 82 (62.6%) patients were fertile. There was no significant difference in CD16/56 and HLA-DR levels depending on pregnancy status, IVF outcomes and infertility factors (p&gt;0.05). The levels of IL-1β and IFN-ɣ differed in the blood serum of patients with and without pregnancy (p=0.041 and p=0.037, respectively). Analysis of groups based on infertility factors showed that there were not significant differences (p&gt;0.05) in the levels of CD16/56, HLA-DR, IL-1β, TNF-α and IFN-ɣ between groups. Conclusions. Our study showed that there is an association between serum levels of IL‒1β and IFN-y and successful pregnancy in the IVF procedure. We did not reveal the other relationships between clinical and immunological parameters in women with IVF procedure.

Pregnancy Benefit of Acupuncture on in vitro Fertilization: A Systematic Review and Meta-Analysis.

Currently, more and more infertility couples are opting for combined acupuncture to improve success rate of in vitro fertilization (IVF). However, evidence from acupuncture for improving IVF pregnancy outcomes remains a matter of debate. To quantitatively summarized the evidence of the efficacy of acupuncture among women undergoing IVF by means of systematic review and meta-analysis. Four English (PubMed, Web of Science, EMBASE, and Cochrane Register of Controlled Clinical Trials) and Four Chinese databases (Wanfang Databases, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodical Database, and SinoMed) were searched from database inception until July 2, 2023. Randomized controlled trials (RCTs) that evaluated the acupuncture's effects for women undergoing IVF were included. The subgroup analysis was conducted with respect to the age of participants, different acupuncture types, type of control, acupuncture timing, geographical origin of the study, whether or not repeated IVF failure, and acupuncture sessions. Sensitivity analyses were predefifined to explore the robustness of results. The primary outcomes were clinical pregnancy rate (CPR) and live birth rate (LBR), and the secondary outcomes were ongoing pregnancy rate and miscarriage rate. Random effects model with I2 statistics were used to quantify heterogeneity. Publication bias was estimated by funnel plots and Egger's tests. A total of 58 eligible RCTs representing 10,968 women undergoing IVF for pregnant success were identifified. Pooled CPR and LBR showed a signifificant difference between acupuncture and control groups [69 comparisons, relative risk (RR) 1.19, 95% confifidence intervals (CI) 1.12 to 1.25, I2=0], extremely low evidence; 23 comparisons, RR 1.11, 95%CI 1.02 to 1.21, I2=14.6, low evidence, respectively). Only transcutaneous electrical acupoint stimulation showed a positive effect on both CPR (16 comparisons, RR 1.17, 95%CI 1.06 to 1.29; I2=0, moderate evidence) and LBR (9 comparisons, RR 1.20, 95%CI 1.04 to 1.37; I2=8.5, extremely low evidence). Heterogeneity across studies was found and no studies were graded as high-quality evidence. Results showed that the convincing evidence levels on the associations between acupuncture and IVF pregnant outcomes were relatively low, and the varied methodological design and heterogeneity might inflfluence the fifindings.

Effect of comprehensive nursing intervention on the outcomes of in vitro fertilization in patients with polycystic ovary syndrome: A randomized controlled study.

To explore the effects of comprehensive nursing intervention on in vitro fertilization (IVF) and pregnancy outcomes in patients with polycystic ovary syndrome (PCOS). A total of 130 patients with PCOS admitted to our hospital from April 2021 to March 2023 were selected as the research subjects. They were evenly divided according to a random number table method. The control group received routine care for the patients, while the study group received comprehensive care for the patients. The IVF, pregnancy outcomes, negative emotional changes, serum and follicular fluid (FF) amyloid-related protein and C-reactive protein (CRP) levels of the 2 groups of patients were compared. The data on IVF rate and pregnancy rate in the study group were significantly better than those in the control group (P < .05). The SAS and SDS scores of the study group patients after intervention were significantly lower than those of the control group (P < .05). After intervention, the levels of serum and FF amyloid associated protein and CRP in the study group were significantly lower than those in the control group (P < .05). Patients with PCOS who receive comprehensive care can increase their probability of IVF, improve their pregnancy outcomes, and have a positive significance in reducing negative emotions.

Risk of Preterm Delivery in Very Advanced Maternal Age Parturients Utilizing In Vitro Fertilization.

Among patients ≥45 years, the birth rate in the United States continues to increase. As fertility declines with age, this cohort often utilizes assisted reproductive technology, specifically in vitro fertilization (IVF). While both advancing maternal age and IVF are independently associated with adverse maternal outcomes, data regarding their additive effect are scant. This article aims to determine if patients who conceive via IVF are at increased risk for preterm birth (PTB) compared to patients with non-IVF pregnancies in a very advanced maternal age (vAMA) cohort (≥45 years). Retrospective cohort study of all pregnant patients ≥45 years old who delivered at a single institution (2014-2021). Those with incomplete delivery/neonatal records or multiples beyond twins were excluded. We compared individuals who conceived via IVF to those who conceived without IVF. The primary outcome was preterm delivery <37 weeks gestation. Secondary outcomes included other adverse perinatal outcomes. Using multivariable logistic regression, we adjusted for multiple gestation as well as confounders found to be significantly different in the univariable analysis and other known risk factors for PTB. In our study cohort of 420 vAMA patients, individuals who underwent IVF were more likely to be older, privately insured, nulliparous, and with a twin gestation. The PTB rate in vAMA patients who underwent IVF was 24.4 compared to 8.4% in patients who did not use IVF (p < 0.001). After adjusting for confounders, IVF was an independent risk factor for PTB <37 weeks in vAMA patients (adjusted odds ratio {aOR] = 4.3, 95% confidence interval [CI]: 1.7-10.4, p = 0.001). In vitro fertilization was also associated with a composite of adverse maternal outcomes (hypertensive disorder of pregnancy, postpartum hemorrhage, blood transfusion, and unplanned hysterectomy) (aOR 1.7, 95% CI [1.1-2.9], p = 0.03). In the vAMA population, conception via IVF is associated with an increased risk of PTB <37 weeks. · This study examines IVF as an independent risk factor for PTB in patients ≥45 years at delivery, which has not been specifically addressed in prior studies.. · In vAMA patients, use of IVF is associated with an increased risk of PTB <37 weeks. These patients also have higher rates of cesarean delivery. Neonates from IVF pregnancies are more likely to be very low birth weight or low birth weight.. · Bodies of research exist for both advanced maternal age and assisted reproductive technology, there is a paucity of data specifically in parturients of vAMA who conceive via IVF..
