Critical care emphasizes critical thinking, focuses on the triggers that lead to disease progression, and attaches great importance to early diagnosis of diseases and assessment of the compensatory capacity of vital organs. Pregnancy-associated atypical hemolytic uremic syndrome (P-aHUS) is relatively rare in the intensive care unit (ICU). Most cases occur within 10 weeks after delivery. Severe cases can be life-threatening. It characterized by microangiopathic hemolytic anemia, decreased platelet count (PLT), and acute kidney injury (AKI). Early clinical diagnosis is difficult due to its similarity to various disease manifestations. On January 28, 2024, a 26-year-old pregnant woman at 26+3 weeks gestation was transferred to the ICU 19 hours post-vaginal delivery due to abdominal pain, reduced urine output, decreased PLT, elevated D-dimer, tachycardia, increased respiratory rate and declined oxygenation. On the day of ICU admission, the critical care physician identified the causes that triggered the acute respiratory and circulatory events based on the "holistic and local" critical care thinking. The condition was stabilized rapidly by improving the capacity overload. In terms of etiological diagnosis, under the guidance of the "point and face" critical care thinking, starting from abnormality indicators including a decrease in hemoglobin (Hb) and PLT and elevated D-dimer and fibrin degradation product (FDP) without other abnormal coagulation indicators, the critical care physician ultimately determined the diagnosis direction of thrombotic microangiopathy (TMA) by delving deeply into the essence of the disease and formulating a laboratory examination plan in a reasonable and orderly manner. In terms of in-depth diagnosis, combining the disease development process, family history, and past history, applying the two-way falsification thinking of "forward and reverse" as well as "questioning and hypothesis", the diagnosis possibilities of preeclampsia, HELLP syndrome [including hemolysis (H), elevated liver function (EL) and low platelet count (LP)], thrombotic thrombocytopenic purpura (TTP), typical hemolytic uremic syndrome (HUS), and autoimmune inflammatory diseases inducing the condition was ruled out. The diagnosis of complement activation-induced P-aHUS was finally established for the patient, according to the positive result of the complement factor H (CFH). Active decision was made in the initial treatment. The plasma exchange was initiated early. "Small goals" were formulated in stages. The "small endpoints" were dynamically controlled in a goal-oriented manner to achieve continuous realization of the overall treatment effect through phased "small goals". On the 5th day of ICU treatment, the trend of microthrombosis in the patient was controlled, organ function damage was improved, and the patient was transferred out of the ICU. It is possible to reach a favorable clinical outcome for critically ill patients by applying a critical care mindset to quickly integrate diagnostic and therapeutic strategies, accurately identifying the triggers and causes that led to the progression of the disease, and using critical care medical techniques for early and effective intervention.

OBJECTIVE:
To evaluate the impact of endometrial polyps (EP) on postoperative pregnancy outcomes in infertile women with endometriosis (EMs).
METHODS:
PubMed, Embase, The Cochrane Library, CNKI, VIP, SinoMed, and WanFang Data databases were searched to include clinical studies on the effect of EP on pregnancy outcomes in patients with EMs, published before August 31, 2020. A meta-analysis was performed using Rev Man 5.3 software after two investigators independently screened the literature, extracted information, and evaluated the risk of bias of the included studies.
RESULTS:
The meta-analysis included ten studies (651 and 1,040 in the combined EP and uncomplicated EP groups, respectively). The spontaneous pregnancy rate, clinical pregnancy rate, and live birth rate were significantly lower in the group with combined EPs than in the group without combined EPs [Odd's ratio ( OR) = 0.63, 95% confidence interval ( CI): 0.50-0.80, P = 0.0001; OR = 0.63, 95% CI: 0.48-0.84, P = 0.001; OR = 0.63, 95% CI: 0.42-0.96, P = 0.03], and the rate of embryonic abortion was significantly higher than that in the uncomplicated EP group [ OR = 3.10, 95% CI: 1.52-6.32, P = 0.002].
CONCLUSION
EP may adversely affect pregnancy outcomes in patients with infertility and EMs. Even after surgical treatment, EP can still reduce natural pregnancy, clinical pregnancy, and live birth rates in infertile women with EMs and increase the risk of embryo arrest in these women.

OBJECTIVE:
To investigate chronic hepatitis C virus (HCV) infection's effect on gestational liver function, pregnancy and delivery complications, and neonatal development.
METHODS:
A total of 157 HCV antibody-positive (anti-HCV[+]) and HCV RNA(+) patients (Group C) and 121 anti-HCV(+) and HCV RNA(-) patients (Group B) were included as study participants, while 142 anti-HCV(-) and HCV RNA(-) patients (Group A) were the control group. Data on biochemical indices during pregnancy, pregnancy complications, delivery-related information, and neonatal complications were also collected.
RESULTS:
Elevated alanine aminotransferase (ALT) rates in Group C during early, middle, and late pregnancy were 59.87%, 43.95%, and 42.04%, respectively-significantly higher than Groups B (26.45%, 15.70%, 10.74%) and A (23.94%, 19.01%, 6.34%) ( P < 0.05). Median ALT levels in Group C were significantly higher than in Groups A and B at all pregnancy stages ( P < 0.05). No significant differences were found in neonatal malformation rates across groups ( P > 0.05). However, neonatal jaundice incidence was significantly greater in Group C (75.16%) compared to Groups A (42.25%) and B (57.02%) ( χ 2 = 33.552, P < 0.001). HCV RNA positivity during pregnancy was an independent risk factor for neonatal jaundice ( OR = 2.111, 95% CI 1.242-3.588, P = 0.006).
CONCLUSIONS
Chronic HCV infection can affect the liver function of pregnant women, but does not increase the pregnancy or delivery complication risks. HCV RNA(+) is an independent risk factor for neonatal jaundice.

OBJECTIVE:
Coronavirus disease 2019 (COVID-19) can result in fatigue and post-exertional malaise; however, whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection exacerbates lower urinary tract symptoms (LUTS) is unclear. This study investigated the association between prenatal SARS-CoV-2 infection and postpartum LUTS.
METHODS:
A multicenter, retrospective cohort study was conducted at two tertiary hospitals in China from November 1, 2022, to November 1, 2023. Participants were classified into infected and uninfected groups based on SARS-CoV-2 antigen results. LUTS prevalence and severity were assessed using self-reported symptoms and the Incontinence Impact Questionnaire-Short Form (IIQ-7). Pelvic floor muscle activity was measured using electromyography following the Glazer protocol. Group comparisons were performed to evaluate the association of SARS-CoV-2 infection with LUTS and electromyography parameters, with stratified analyses conducted using SPSS version 26.0.
RESULTS:
Among 3,652 participants (681 infected, 2,971 uninfected), no significant differences in LUTS prevalence or IIQ-7 scores were observed. However, SARS-CoV-2 infection was an independent factor influencing the electromyographic activity of the pelvic floor muscles (mean tonic contraction amplitudes), regardless of delivery mode ( P = 0.001).
CONCLUSION
Prenatal SARS-CoV-2 infection was not significantly associated with an increased risk of postpartum LUTS but independently altered pelvic floor muscle electromyographic activity, suggesting potential neuromuscular effects.

Human cytomegalovirus (HCMV) poses a significant risk of neural damage during pregnancy. As the most prevalent intrauterine infectious agent in low- and middle-income countries, HCMV disrupts the development of neural stem cells, leading to fetal malformations and abnormal structural and physiological functions in the fetal brain. This review summarizes the current understanding of how HCMV infection dysregulates the Wnt signaling pathway to induce fetal malformations and discusses current management strategies.

Hydronephrosis is a common urological disease,and pregnancy with hydronephrosis is also common.However,it is extremely rare that patients suffering from hydronephrosis after delivery cannot recover on their own.Moreover,due to the no specificity of clinical manifestations,it is easy to be ignored by clinicians.This paper reports a solitary kidney patient with severe dilatation and hydronephrosis of the kidney and ureter that were caused by late pregnancy,and the hydrops could not recover spontaneously after delivery.In addition,the methods of open surgery,ureteroscopy,and ureteral stent placement for many times in other hospital were ineffective for her.The purpose of this study is to improve the attention of clinicians to hydronephrosis during pregnancy and after delivery and provide the reference for clinical treatment.

To improve clinicians' understanding, and to explore the diagnosis and treatment of pregnancy complicated with patent urachus. The clinical symptoms, ultrasound images, and delivery outcome of the pregnancy complicated with patent urachus were reported, and the literature was reviewed. The patient had umbilical leakage as a young child occasionally, the symptom of leakage was not obvious after she was 10 years old, and there was no asymptomatic before pregnancy and in the first and second trimesters. Umbilical leakage was present at gestational 33 weeks, and ultrasound showned a tubular structure (0.7 cm in width) was connected between the top of the bladder and the umbilicus, and there was anechoic areas inside. The pregnancy complicated with patent urachus was diagnosed. The patient was checked regularly, and kept the umbilicus clean and dry. Premature rupture of membranes occured at gestational 39 weeks 4 days. The patient was admitted to the obstetrics department, and she deliveried finally. After delivery, the symptoms of umbilical leakage urine relieved, and an elective resection of abnormal urachus was planned. The patent urachus creates a tube connection between the umbilicus and the anterosuperior wall of the bladder, it was termed an median umbilical ligament at birth as usual, which still communicated with the bladder after birth. The main clinical manifestations were umbilical leak and infection, which were the main diagnostic basis. Ultrasound, CT and MRI were important auxi-liary examination methods.The patients with symptoms in the neonatal and early childhood period were managed actively and had the potential for self resolution, especially for the children younger than 1 year. Therefore, patients under 1 year of age were offered surgery only if they had recurrent infections or failed to selfresolve. It is recommended to remove abnormal urachus before pregnancy for the women complica-ted with patent urachus. If the patent urachus was found during pregnancy, the umbilicus should be kept clean and dry to avoid infection. The pregnancy complicated with patient urachus is not contraindicated to vaginal delivery.

BACKGROUND:
Although the influence of maternal distress during pregnancy on newborn Apgar scores has been studied in various populations, there is limited research specifically addressing this issue among Asian women. This study of Japanese women aims to investigate the association between maternal distress during pregnancy and the risk of a low 5-min-Apgar score among newborns.
METHODS:
We analyzed data from 87,765 mother-newborn pairs in the Japan Environment and Children's Study. Using multivariable logistic regression, we estimated odds ratios (OR) and 95% confidence intervals (CI) for low Apgar scores (<7) at 5 minutes about maternal distress during early and mid-late pregnancy, as measured by the Kessler Psychological Distress Scale (K6). Apgar scores were obtained from newborns' medical records.
RESULTS:
A higher risk of low Apgar score in newborns at 5 minutes was found in mothers with moderate to severe distress than in those with low distress during mid-late pregnancy. The adjusted OR (95% CI) was 1.22 (1.05-1.42) for moderate distress (K6 = 5-12) and 1.42 (1.00-2.01) for severe distress compared to low distress (p for trend = 0.002). The positive association between maternal distress and the risk of low Apgar score was observed in preterm birth (<37 weeks) and low birth weight (<2,500 g) but not in term birth and normal birth weight.
CONCLUSION
Maternal distress during mid-late pregnancy was positively associated with the risk of low Apgar score of newborns, specifically in preterm birth and low birth weight.

OBJECTIVE:
To explore the genetic testing outcomes of a fetal family with Thyroid dyshormonogenesis type 5 (TDH5) and familial Neurofibromatosis type 1 (NF1), and to clarify the association between clinical manifestations and genetic variations.
METHODS:
One case of a TDH5 combined with familiar NF1 fetus treated at Gansu Maternal and Child Health Hospital in January 2024 was selected as the research subject. The clinical and family history data of the fetus were collected by retrospective research method. 10-15 mL of fetal amniotic fluid, and 2-3 mL of peripheral blood from the parents, sister, and grandfather of the fetus were collected, and genomic DNA was extracted for trio whole-exome sequencing (trio-WES). The Sanger sequencing was utilized to validate candidate variants for family verification. According to the Standards and Guidelines for the Interpretation and Reporting of Sequence Variants of the American Society of Medical Genetics and Genomics (ACMG) (hereafter referred to as the ACMG guidelines), the pathogenicity of the detected variants was classified. This study has been approved by the Medical Ethics Committee of Gansu Maternal and Child Health Hospital [Ethics No.(2021)GSFY(65)].
RESULTS:
The fetal ultrasound indicated the nuchal translucency (NT) thickening, and the thyroid function test results of the sister showed an increase in thyroid stimulating hormone and a decrease in free thyroid hormone. Simultaneously, there were cafe-au-lait macules of various sizes in multiple parts of the body of the sister, and the mother had a similar cafe-au-lait macules phenotype. The trio-WES results revealed that there was a c.413dupA (p.Tyr138*) frameshift mutation in exon4 and c.573G>A (p.Trp191*) nonsense mutation in exon5 of the fetal DUOXA2, which were inherited from the mother and father, respectively. In accordance with the ACMG guidelines, they were classified as pathogenic variant (PVS1+PM2_Supporting+PM3) and likely pathogenic variant (PVS1+PM2_Supporting), respectively. And the nonsense mutation c.6972C>A (p.Tyr2264*) was detected in exon46 of the NF1 in the fetus, inherited from the mother maternal grandfather. The genetic testing results of the first sister and proband in this case were consistent, and the DUOXA2 and NF1 of the second sister were both wild-type. According to the ACMG guidelines, c.6972C>A (p.Tyr2264 *) was classified as pathogenic variant (PVS1+PS4_Supporting+PP4+PM2_Supporting).
CONCLUSION
The mutations in the DUOXA2 gene c.413dupA (p.Tyr138*) and c.573G>A (p.Trp191*), and the NF1 gene c.6972C>A (p.Tyr2264*) might be the genetic causes of TDH5 combined with familiar NF1 in proband. The discovery of the DUOXA2 gene c.573G>A (p.Trp191*) enriches the spectrum of pathogenic gene variations.
