Navigating Uncertain Waters: First-Trimester Screening's Role in Identifying Neonatal Complications.

Background: Contemporary diagnostic methods aimed at assessing neonatal outcomes predominantly rely on the medical history of pregnant women. Ideally, universal biomarkers indicating an increased risk of delivering infants in poor clinical condition, with a heightened likelihood of requiring hospitalization in a Neonatal Intensive Care Unit (NICU), would be beneficial for appropriately stratifying pregnant women into a high-risk category. Our study evaluated whether biochemical and ultrasonographical markers universally used in first-trimester screenings for non-heritable chromosomal aberrations could serve this purpose. Methods: This study encompassed 1164 patients who underwent first-trimester screening, including patient history, ultrasound examinations, and biochemical tests for pregnancy-associated plasma protein-A (PAPP-A) and the free beta-HCG subunit (fbHCG), from January 2019 to December 2021. The research concentrated on the correlation between these prenatal test results and neonatal outcomes, particularly Apgar scores, umbilical blood pH levels, and the necessity for NICU admission. Results: In our cohort, neonates scoring lower than 8 on the Apgar scale at birth exhibited lower concentrations of PAPP-A in the first trimester, both in raw and normalized values (PAPP-A MoM 0.93 vs. 1.027, p = 0.032). We also observed a higher pulsatility index in the venous duct in the first trimester in full-term neonates born with <8 points on the Apgar scale. Additionally, newborns born with an umbilical blood pH < 7.2 had lower normalized first-trimester PAPP-A concentrations (0.69 vs. 1.01 MoM, p = 0.04). We also noted that neonates requiring NICU hospitalization post-delivery had lower first-trimester bHCG concentrations (0.93 MoM vs. 1.11 MoM, p = 0.03). However, none of the correlations in our study translated into a robust prognostic ability for predicting dichotomous outcomes. All areas under the curve achieved a value < 0.7. Conclusions: Low concentrations of PAPP-A and free bHCG subunit in the first trimester may be associated with poorer clinical and biochemical conditions in neonates post-delivery. However, the relationship is weak and has limited predictive capability. Further research evaluating these relationships is necessary for the appropriate stratification of pregnant women into high-risk categories for neonatological complications.

Enhanced Diagnostic Capabilities: Ultrasound Imaging of Fetal Alimentary Tract Obstruction with Advanced Imaging Technologies.

BACKGROUND Congenital malformations of the alimentary tract constitute 5% to 6% of newborn anomalies, with congenital intestinal atresia being a common cause of alimentary tract obstruction. This study explores advanced ultrasound diagnostic possibilities, including 2D, HDlive, HDlive inversion, and HDlive silhouette imaging modes, through the analysis of 3 cases involving duodenal and intestinal obstructions. Congenital malformations of the alimentary tract often present challenges in prenatal diagnosis. The most prevalent defect is congenital intestinal atresia leading to alimentary tract obstruction, with an incidence of approximately 6 in 10 000 births. We focused on advanced ultrasound diagnostic techniques and their applications in 3 cases of duodenal and intestinal obstructions. CASE REPORT Three cases were examined using advanced ultrasound imaging modes. The first patient, diagnosed at week 35 of gestation, revealed stomach and duodenal dilatation. The second, identified at week 32, had the characteristic "double bubble" symptom. The third, at week 31, also had double bubble symptom and underwent repeated amnioreduction procedures. HDlive, HDlive inversion, and HDlive silhouette modes provided intricate visualizations of the affected organs. Prenatal diagnosis of alimentary tract obstruction relies on ultrasound examinations, with nearly 50% of cases being diagnosed before birth. CONCLUSIONS Advanced ultrasound imaging modes, particularly HDlive silhouette, play a crucial role in diagnosing fetal alimentary tract obstruction. These modes offer detailed visualizations and dynamic evaluations, providing essential insights for therapeutic decisions. The study emphasizes the importance of sustained fetal surveillance, a multidisciplinary approach, and delivery in a level III referral center to ensure specialized care for optimal outcomes.

Hyperglycemia in pregnancy - prevalence and perinatal outcomes. A retrospective multicenter cohort study in Poland.

OBJECTIVES: Hyperglycemia in pregnancy (HIP) is one of the most common complications of pregnancy. Recently adopted new criteria for the diagnosis of HIP as well as the greater prevalence of risk factors could have a significant impact on HIP prevalence. The objective of the study was to assess the rates of HIP and the associated complications. MATERIAL AND METHODS: This was a retrospective analysis of clinical records from pregnant women who delivered in eight tertiary hospitals in Poland in 2016. RESULTS: The number of pregnant women with hyperglycemia totaled 1280 (7.25%), including gestational diabetes mellitus (GDM) in 1169 (6.62%) women and pregestational diabetes mellitus (PGDM) in 111 (0.63%). In addition to dietary modifications, 477 (41% of the GDM group) women received medical treatment (GDMG2). In women with PGDM multiple daily insulin injections (MDI) were used in 53 (47.7%) cases, continuous subcutaneous insulin infusions (CSII) in 57 (51.3%) cases and one woman was treated with metformin. The rate of cesarean sections was 69.4% and 62.9% for PGDM and GDM, respectively. Large-for-gestational-age (LGA) infants accounted for 38% and 21% of births in the PGDM and GDM groups, respectively. Of note are high rates of hyperbilirubinemia in infants born to mothers treated with insulin (13.5% for PGDM and 14.4% for GDMG2) vs infants born to mothers with diet (GDMG1) (3.4%). CONCLUSIONS: In Poland, the prevalence of HIP has nearly doubled in the past twenty years. Even with appropriate management, HIP is a significant risk factor for a cesarean section delivery, bearing an LGA infant and adverse neonatal outcomes.

A New Aberration in the VPS33B Gene Leads to Full-Symptom ARCS1.

BACKGROUND ARCS1 is an acronym for arthrogryposis, renal dysfunction, and cholestasis. It is a congenital malfunction with autosomal recessive inheritance, and, unfortunately, its prognosis is still poor. It is believed that VPS33B is altered in 75% of cases and that the VIPAR gene is altered in approximately 25% of them. CASE REPORT An affected child was born from the first pregnancy of 26-year-old mother and a 30-year-old father with no previous medical history and no genetic conditions. The first clinical symptoms were observed at the end of the child's second week of life. The mother reported the child has decreasing body weight and loss of appetite. After admission to the ward, the child was apathetic and sleepy. Symptoms of conjunctivitis, pale and dry skin, and mild face and mild body dysmorphia were observed. CONCLUSIONS Laboratory tests revealed proteinuria of up to 1.36 g/l and glycosuria of up to 28 mmol/l, as well as fluctuating metabolic acidosis. The bilirubin level reached 6.62 mg/dl, along with alkaline phosphatase at 470 U/l. Moreover, hypothyroidism with TSH at 16.71 uU/ml was observed. Because of the co-occurrence of cholestasis and renal dysfunction, molecular testing was done. The 17th exon of VPS33B was sequenced by Sanger DNA sequencing method. To the best of our knowledge, this is the first report of homozygotic mutation c.1235_1236delinsG (p.Pro412ArgfsTer7) in the VPS33B gene. The risk of transfer of the mutation to future descendants was calculated as 25%. Due to the wide landscape of molecular alternation in the 17th exon of the VPS33B gene, we propose using Sanger whole-exon sequencing as a first-choice diagnostic test.

[Results of pap smears and immunocytochemical detection of the p16 and Ki67 proteins in women with cervical intraepithelial neoplasia and cervical cancer]. / Wyniki badan cytologicznych i immunocytochemiczna identyfikacja bialek p16 i Ki67 u kobiet ze sródnablonkowa neoplazja i rakiem szyjki macicy.

OBJECTIVE: The aim of the study was to assess the diagnostic value of pap smears and detection of the p16 and Ki67 proteins in women with cervical intraepithelial neoplasia (CIN). MATERIALS AND METHOD: 630 women, aged between 25 and 65, with abnormal pap smears were included into the study All patients had a control pap smear and in each case punch biopsy with endocervical curettage were performed under the control of a colposcope. The presence of p16 and Ki67 proteins was detected using the CINtecPlus test. The results of the research were statistically assessed. RESULTS: Abnormal pap smears were found in 82.5% (520/630) of the studied women. In 40% (252/630) of the cases the LSIL changes were found. The recognition of ASC-US concerned 35.2% (222/630) of the patients, and pap smears with the HSIL result were found in 7.3% (46/630) of the women. In 17.5% (110/630) of the patients the result of the cytological examination was normal. Abnormal results of the pap smears were found significantly statistically more frequently (p<0,0001) in women with cervical intraepithelial neoplasia (CIN). The results of the CINtecPlus test were positive in 68,4% of women with CIN and in 33,3% of patients with normal cervix. In the group of women with precancerous lesions (HGSIL/CIN2+) the diagnostic accuracy of the pap smear was 41% for the cytological results ASC-US, 56% LSIL and 73% for detection of HSIL. Immunocytochemical detection of p16 and Ki67 proteins gained the highest accuracy (78%) in recognition of cervical precancerous lesions. CONCLUSION: 1. ASC-US and LSIL cytological recognition has low accuracy in the diagnosis of CIN2+ cervical changes. 2. Cytological recognition of HSIL has the highest accuracy in the diagnosis of CIN2+ changes. 3. Immunocytochemical detection of p16 and Ki67 proteins is more accurate in recognizing precancerous states and cervical cancer than cytological examination. 4. Immunocytochemical detection of the p16 and Ki67 proteins can be used to triage patients with atypical squamous cells of undetermined significance and low grade squamous intraepithelial lesions.
