OBJECTIVE: To describe intrapartum fetal monitoring methods used in all births in Norway in 2019-2020, assess adherence to national guidelines, investigate variation by women\'s risk status, and explore associations influencing monitoring practices.
METHODS: A nationwide population-based study. We collected data about all pregnancies with a gestational age ≥ 22 weeks during 2019-2020 from the Medical Birth Registry of Norway. We used descriptive analyses, stratified for risk status, to examine fetal monitoring methods used in all deliveries. Univariable and multivariable logistic regression models were used to determine factors associated with monitoring with cardiotocography (CTG) in low-risk, straightforward births.
RESULTS: In total, 14 285 (14%) deliveries were monitored with only intermittent auscultation (IA), 46214 (46%) with only CTG, and 33417 (34%) with IA and CTG combined. Four percent (2 067/50 533) of women with risk factors were monitored with IA only. Half (10589/21 282) of the low-risk women with straightforward births were monitored with CTG. Maternal and fetal characteristics, size of the birth unit and regional practices influenced use of CTG monitoring in this group.
CONCLUSIONS: Most births are monitored with CTG only, or combined with IA. Half the women with low-risk pregnancies and straightforward births were monitored with CTG although national guidelines recommending IA.

UNASSIGNED: Myotonic dystrophy type 1 (DM1) is a hereditary neuromuscular disorder affecting the central nervous system (CNS). Although sex differences have been explored in other neuromuscular disorders, research on this topic in DM1 remains limited. The present study aims to analyze sex differences (both the patient\'s and disease-transmitting parent\'s sex) with a focus on CNS outcomes.
UNASSIGNED: Retrospective data from 146 non-congenital DM1 patients were analyzed, including clinical, molecular, neuropsychological, and neuroradiological data. Sex and inheritance pattern differences were analyzed using t-tests, and ANOVA analyses were conducted to address the interactions.
UNASSIGNED: Overall, no significant sex differences were observed except in certain cognitive domains. However, individuals with maternal inheritance showed larger CTG expansion size, lower estimated IQs, and poorer performance on visual memory, executive functions, and language domains than those with paternal inheritance. Notably, IQ performance was independently influenced by inheritance pattern and CTG expansion.
UNASSIGNED: This study is the first to delve into sex differences in DM1 with a focus on CNS outcomes. While the results revealed the absence of a sex-specific clinic-molecular profile, more substantial CNS differences were observed between patients with maternal and paternal inheritance patterns. The hypothetical existence of genomic imprinting and its potential mechanism are discussed. These findings hold potential implications for aiding clinical management by improving genetic counseling and predicting disease severity and prognosis.

Background: Following the development of the Royal Australian College of Obstetricians and Gynaecologists Intrapartum Fetal Surveillance Guideline in 2003, an education program was developed to support guideline implementation and clinical practice. It was intended that improved clinician knowledge, particularly of cardiotocography, would reduce rates of intrapartum fetal morbidity and mortality. The program contains a multiple-choice assessment, designed to assess fetal surveillance knowledge and the application of that knowledge. We used the results of this assessment over time to evaluate the impact of the education program on clinicians\' fetal surveillance knowledge and interpretive skills, in the immediate and longer-term. Methods: We undertook a retrospective analysis of the assessment results for all participants in the Fetal Surveillance Education Program, between 2004 and 2018. Classical Test Theory and Rasch Item Response Theory analysis were used to evaluate the statistical reliability and quality of the assessment, and the measurement invariance or stability of the assessments over time. Clinicians\' assessment scores were then reviewed by craft group and previous exposure to the program. Results: The results from 64,430, broadly similar assessments, showed that participation in the education program was associated with an immediate improvement in clinician performance in the assessment. Performance improvement was sustained for up to 18 months following participation in the program and recurrent participation was associated with progressive improvements. These trends were observed for all craft groups (consultant obstetricians, doctors in training, general practitioners, midwives, student midwives). Conclusions: These findings suggest that the Fetal Surveillance Education Program has improved clinician knowledge and the associated cognitive skills over time. The stable difficulty of the assessment tool means any improvement in clinician\'s results, with ongoing exposure to the program, can be reliably assessed and demonstrated. Importantly this holds true for all craft groups involved in intrapartum care and the interpretation of cardiotocography.

BACKGROUND: Amniotic banding is a rare condition that can lead to structural limb anomalies, fetal distress and adverse obstetric outcomes. The main hypothesis for its etiology is a rupture of the amniotic membrane in early pregnancy, with the formation of tightly entangling strands around the fetus. These strands can constrict, incise, and subsequently amputate limb parts, the neck or head. More rarely, the amniotic banding can affect the umbilical cord, leading to fetal distress or potential intra-uterine fetal demise.
OBJECTIVE: We present a unique case of a 26-week pregnant woman who attended a polyclinical consultation due to reduced fetal movements with concerning cardiotocography (CTG) findings. A review of the literature about amniotic banding of the umbilical cord was conducted as well, identifying diagnostic and interventional options for the obstetrician\'s practice.
METHODS: This is a case report, alongside a review of the literature.
RESULTS: The CTG indicated fetal distress, prompting an emergency caesarean section (C-section). Upon delivery, the neonate exhibited signs of amniotic band sequence, with distal phalangeal defects on the right hand and severe constriction of the umbilical cord caused by amniotic strands, the latter precipitating fetal hypoxia. Direct ultrasound diagnosis remains a challenge in the absence of limb amputation, yet indirect signs such as distal limb or umbilical doppler flow abnormalities and distal limb edema may be suggestive of amniotic banding. MRI is proposed as an adjuvant diagnostic tool yet does not present a higher detection rate compared to ultrasound. Fetoscopic surgery to perform lysis of the amniotic strands with favorable outcome has been described in literature.
CONCLUSIONS: This case presents the first reported survival of an extremely preterm fetus in hypoxic distress as a cause of amniotic banding of the umbilical cord, with a rare degree of incidental timing. Ultrasound diagnosis remains the gold standard. Obstetrical vigilance is warranted, with fetal rescue proven to be feasible.

BACKGROUND: The use of cardiotocography (CTG) to improve neonatal outcomes is controversial. The medical settings, subjects, utilizations, and interpretation guidelines of CTG are unclear for low- and middle-income countries (LMICs).
OBJECTIVE: To assess and review CTG use for studies identified in LMICs and provide insights on the potential for effective use of CTG to improve maternal and neonatal outcomes.
METHODS: The databases Medline, CINAHL, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched for published and unpublished literature through September 2023.
METHODS: Publications were identified which were conducted in LMICs, based on the World Bank list of economies for 2019; targeting pregnant women in childbirth; and focusing on the utilization of CTG and neonatal outcomes.
METHODS: Publications were screened, and duplicates were removed. A scoping review was conducted using PRISMA-ScR guidelines.
RESULTS: The searches generated 1157 hits, of which 67 studies were included in the review. In the studies there was considerable variation and ambiguity regarding the study settings, target populations, utilizations, timing, frequency, and duration of CTG. While cesarean section rates were extensively investigated as an outcome of studies of CTG itself and the effect of additional techniques on CTG, other clinically significant outcomes, including neonatal mortality, were not well reported.
CONCLUSIONS: Variations and ambiguities were found in the use of CTG in LMICs. Due to the limited amount of evidence, studies are needed to examine CTG availability in the context of LMICs.

Purpose The aim of this guideline was to find evidence on whether carrying out Doppler examinations and CTGs in low-risk cohorts of pregnant women improves outcomes. Methods First, a systematic search for guidelines was carried out. Identified guidelines were evaluated using the DELPHI instrument of the AWMF. Three guidelines were found to be suitable to evaluate CTG. Two DEGUM best practice guidelines were judged suitable to describe the methods. All studies on this issue were additionally analyzed using 8 PICO questions. A structured consensus of the participating professional societies was achieved using a nominal group process and a structured consensus conference moderated by an independent moderator. Recommendations No antepartum Doppler sonography examinations should be carried out in low-risk cohorts in the context of antenatal care. No antepartum CTG should be carried out in low-risk cohorts. Note The guideline will be published simultaneously in the official journals of both professional societies (i.e., Geburtshilfe und Frauenheilkunde for the DGGG and Ultraschall in der Medizin/European Journal of Ultrasound for the DEGUM).

BACKGROUND: The incidence of myotonic dystrophy type 1 (DM1), a disease with great phenotypic variety, in our region is unknown. This study aims to estimate the incidence of DM1 at our hospital (a reference centre in Aragon, Spain) and to identify the characteristics of our population (genotype-phenotype correlation).
METHODS: Retrospective, descriptive study of 459 patients classified according to the number of CTG repeats, as follows: normal (5-35), premutation (36-50), protomutation (51-80), small expansions (81-150), intermediate expansions (151-1000), and large expansions (> 1000). Furthermore, according to clinical phenotype, patients were categorised as unaffected (5-50 CTG repeats), mild form or asymptomatic (51-150), classical form (151-1000), and severe form (> 1000).
RESULTS: The incidence of DM1 was 20.61 cases per million person-years (95% CI, 19.59-21.63). An inverse correlation was observed between the number of CTG repeats and the age at genetic diagnosis (ρ = -0.547; 95% CI, -0.610 to -0.375; P < .001). CTG5 was the most frequent polymorphic allele in healthy individuals. Of all patients with DM1, 28.3% presented the mild or asymptomatic form, 59.1% the classical form, and 12.6% the severe form. Inheritance was maternal in 35.1% of cases, paternal in 59.4%, and uncertain in 5.5%. In mild forms, frontal balding in men was the most prevalent phenotypic trait, as well as myotonia and cataracts, while in the classical form, ptosis, facial weakness, voice and pronunciation alterations, myotonia, and fatigue/sleepiness were most frequent.
CONCLUSIONS: The incidence of DM1 in Aragon is significant. Multidisciplinary study of the phenotype of patients with DM1 is key to early diagnosis and personalised management.

Cardiotocography (CTG) is a widely used technique to monitor fetal heart rate (FHR) during labour and assess the health of the baby. However, visual interpretation of CTG signals is subjective and prone to error. Automated methods that mimic clinical guidelines have been developed, but they failed to improve detection of abnormal traces. This study aims to classify CTGs with and without severe compromise at birth using routinely collected CTGs from 51,449 births at term from the first 20 min of FHR recordings. Three 1D-CNN and LSTM based architectures are compared. We also transform the FHR signal into 2D images using time-frequency representation with a spectrogram and scalogram analysis, and subsequently, the 2D images are analysed using a 2D-CNNs. In the proposed multi-modal architecture, the 2D-CNN and the 1D-CNN-LSTM are connected in parallel. The models are evaluated in terms of partial area under the curve (PAUC) between 0-10% false-positive rate; and sensitivity at 95% specificity. The 1D-CNN-LSTM parallel architecture outperformed the other models, achieving a PAUC of 0.20 and sensitivity of 20% at 95% specificity. Our future work will focus on improving the classification performance by employing a larger dataset, analysing longer FHR traces, and incorporating clinical risk factors.

OBJECTIVE: This study aimed to describe catheter tip granuloma (CTG) formation in a patient on ultralow-dose, low-concentration morphine via intrathecal (IT) drug delivery system (IDDS) and to review literature for reports of IT granuloma formation and association with drug type, drug dose, and drug concentration.
METHODS: This review describes diagnosis and management of a patient with CTG on ultralow-dose, low-concentration morphine. PubMed data base search was conducted from January 1990 to July 2021 for original articles on CTG formation in humans getting intrathecal analgesics. Data were extracted on indications for IDDS, time to detect CTG, and type of drug/s with drug doses and concentrations. Percentages and average with range for age, sex, duration of infusion, drug doses, and drug concentrations were calculated.
RESULTS: We describe CTG formation and spinal cord compression with worsening of sensorimotor deficits in a patient receiving intrathecal morphine at ultralow dose (0.6 mg/d) and low concentration (1.2 mg/mL), which is the lowest reported morphine dose associated with CTG in the literature. Our literature review shows all IT drugs have the potential for granuloma formation, and there is no drug with granuloma-inhibiting effect.
CONCLUSIONS: There is no drug, dose, or concentration that has granuloma-sparing effect. It is imperative to maintain vigilance for potential CTG in all patients with IDDS. Routine monitoring and prompt evaluation for any unexplained symptoms or change in neurologic status from baseline is critical in early detection and treatment of CTG.

Cryptophanes show different conformations in solution and solid state depending upon various factors, such as the length of connecting linkers, medium, and nature of the incoming guest molecule(s). A cyclotriguaiacylenes (CTG) based cryptophane molecule was synthesized using click chemistry containing three triazole linkers and studied as well. This molecule shows two conformations, out-out crown-crown (CC), and out-in CC, in the presence or absence of guest molecule(s), as studied both in solution and solid state. The out-in CC, in which both CTG fragments are in crown conformation with one crown sitting above the other, could be obtained by slow escape of the trapped acetone molecules from out-out CC in solid state. This transformation could be obtained through a single-crystal-to-single-crystal (SCSC) transformation from a large volume out-out CC to a smaller volume out-in CC conformation which is also supported by density functional theory calculations.
