Perinatal outcomes among pregnant patients with peripartum coronavirus disease 2019 infection.

Evaluate maternal and neonatal outcomes in peripartum coronavirus disease 2019 (COVID-19) positive women. A retrospective cohort study was conducted, comparing outcomes between women with and without peripartum COVID-19. All singleton deliveries from June 2020 to January 2022 were included. Univariate analysis was followed by multivariate analysis. Of 26,827 singleton deliveries, 563 women had peripartum COVID-19, associated with preterm deliveries both near-term and remote from term [adjusted odds ratio (aOR) 1.6 and 2.0, respectively, p=0.007 and 0.003]. Women with peripartum COVID-19 had a significantly higher rate of disseminated intravascular coagulation (DIC) (aOR 23.0, p<0.001). Conversely, peripartum COVID-19 peripartum COVID-19 was negatively associated with premature rupture of membranes and prolonged maternal length of stay (aOR 0.7 and 0.5, respectively, p=0.006 and <0.001). In cesarean delivery (CDs), patients with COVID-19 had higher rate of urgent CDs (75.5 vs. 56.1%, p<0.001), higher rate of regional anesthesia (74.5 vs. 64.9%, p=0.049), and longer anesthesia duration (86.1 vs. 53.4 min, p<0.001). CD rate due to non-reassuring fetal heart rate (NRFHR) was significantly higher in women with COVID-19 (29.6 vs. 17.4%, p=0.002). Conversely, CDs rate due to history of previous single CD was significantly higher in patients without COVID-19 diagnosis (13.6 vs. 4.1%, p=0.006). Concerning neonatal outcomes, an associationhas been observed between COVID-19 and low one-minute APGARscore <5,as well as neonatal COVID-19 infection (aOR 61.8 and 1.7 respectively, p<0.001 and p=0.037). Peripartum COVID-19 is associated with preterm deliveries, urgent CDs and DIC, potentially aligning with the infection's pathophysiology and coagulation alterations.

Unusual presentation of Sjogren’s syndrome during pregnancy: a case report

BackgroundPregnancy imposes significant physiological changes, including alterations in electrolyte balance and renal function. This is especially important because certain disorders might worsen and make people more susceptible to electrolyte abnormalities. One such condition is Sjogren's syndrome (SS), an autoimmune disease that can cause distal renal tubular acidosis (dRTA). This case report offers a unique perspective on the intricate physiological interplay during pregnancy, emphasizing the critical importance of recognizing and managing electrolyte abnormalities, particularly in the context of autoimmune disorders such as Sjogren’s syndrome.Case presentationWe report a case of a 31-year-old pregnant Indian woman at 24 weeks gestation presenting with fever, gastrointestinal symptoms, and progressive quadriparesis followed by altered sensorium. Severe hypokalaemia and respiratory acidosis necessitated immediate intubation and ventilatory support. Investigations revealed hypokalaemia, normal anion gap metabolic acidosis, and positive autoimmune markers for SS. Concurrently, she tested positive for IgM Leptospira. Management involved aggressive correction of electrolyte imbalances and addressing the underlying SS and leptospirosis.ConclusionThis case underscores that prompt recognition and management are paramount to prevent life-threatening complications in pregnant patients with autoimmune disease. This report sheds light on the unique challenge of managing hypokalaemic quadriparesis in the context of Sjogren’s syndrome during pregnancy.

SAGES guidelines for the use of laparoscopy during pregnancy.

When pregnant patients present with nonobstetric pathology, the physicians caring for them may be uncertain about the optimal management strategy. The aim of this guideline is to develop evidence-based recommendations for pregnant patients presenting with common surgical pathologies including appendicitis, biliary disease, and inflammatory bowel disease (IBD). The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Guidelines Committee convened a working group to address these issues. The group generated five key questions and completed a systematic review and meta-analysis of the literature. An expert panel then met to form evidence-based recommendations according to the Grading of Recommendations Assessment, Development, and Evaluation approach. Expert opinion was utilized when the available evidence was deemed insufficient. The expert panel agreed on ten recommendations addressing the management of appendicitis, biliary disease, and IBD during pregnancy. Conditional recommendations were made in favor of appendectomy over nonoperative treatment of appendicitis, laparoscopic appendectomy over open appendectomy, and laparoscopic cholecystectomy over nonoperative treatment of biliary disease and acute cholecystitis specifically. Based on expert opinion, the panel also suggested either operative or nonoperative treatment of biliary diseases other than acute cholecystitis in the third trimester, endoscopic retrograde cholangiopancreatography rather than common bile duct exploration for symptomatic choledocholithiasis, applying the same criteria for emergent surgical intervention in pregnant and non-pregnant IBD patients, utilizing an open rather than minimally invasive approach for pregnant patients requiring emergent surgical treatment of IBD, and managing pregnant patients with active IBD flares in a multidisciplinary fashion at centers with IBD expertise.

Airway management and pulmonary aspiration during surgical interventions in pregnant women in the 2nd/3rd trimester and immediate postpartum – a retrospective study in a tertiary care university hospital

BackgroundPregnancy is associated with an increased risk of pulmonary aspiration during general anaesthesia, but the incidence of this complication is not well defined.MethodsWe performed a retrospective database review in a tertiary care university hospital to determine the incidence of pulmonary aspiration in pregnant patients undergoing endotracheal intubation, with and without Rapid Sequence Induction (RSI), as well as face-mask ventilation and supraglottic airway devices. We included Patients in the 2nd or 3rd trimester of pregnancy and immediate postpartum undergoing surgical procedures. The primary endpoint was the occurrence of pulmonary aspiration.ResultsData from 2,390 patients undergoing general anaesthesia for cerclage of cervix uteri, manual removal of retained placenta, repair of obstetric laceration, or postpartum bleeding were retrospectively evaluated. A supraglottic airway device or face-mask ventilation was used in 1,425/2,390 (60%) of patients, while 638/2,390 (27%) were intubated. RSI was used in 522/638 (82%) of patients undergoing tracheal intubation, or 522/2,390 (22%) of the entire cohort. In-depth review of the charts, including 54 patients who had been initially classified as “possible pulmonary aspiration" by anaesthetists, revealed that this adverse event did not occur in the cohort.ConclusionsIn conclusion, in this obstetric surgery patient population at risk for pulmonary aspiration, supraglottic airway devices were used in approximately 60% of cases. Yet, no aspiration event was detected with either a supraglottic airway or endotracheal intubation.

Maternal opioid use during pregnancy and the risk of neonatal opioid withdrawal syndrome in the offspring.

Neonatal opioid withdrawal syndrome (NOWS) is caused by sudden cessation from in utero exposure to opioids. The indications for opioid use during pregnancy are diverse including medication for opioid use disorder and analgesia. The opioid dose typically depends on the indication, with higher doses used for medication for opioid use disorder and lower doses used for analgesia. The aim of this study was to investigate the relationship between maternal opioid dose during pregnancy and the risk of NOWS. We conducted a historical multicenter cohort study of neonates prenatally exposed to opioids in Eastern Denmark during a six-year period from 2013 to 2018. The data was extracted from reviewing the individual's medical record(s), which were identified through a search of the Danish National Patient Register. Four groups (quartiles) according to maternal opioid dose during the last four weeks prior to delivery were compared. Unadjusted and adjusted logistic regression analyses were conducted to examine the risk of NOWS while controlling for relevant covariates. A total of 130 in utero opioid exposed neonates were included. The majority of the pregnant patients (88%) were treated with opioids for analgesic purposes. Overall, 52% of neonates developed NOWS. The cumulative incidence of NOWS was 21%, 28%, 67% and 91% at maternal average daily dose of morphine milligram equivalent during the last four weeks prior to delivery of 0.7-14 (group I), 14.3-38.6 (group II), 40-90 (group III) and 90.9-1440 (group IV), respectively. Compared to group I the adjusted odds (aOR) of NOWS increased significantly in group III (aOR 10.6 [2.9-39.1]) and group IV (aOR 37.8 [7.6-188.2]) but not in group II (aOR 1.5 [0.4-5.2]). No cases of NOWS were reported at maternal dose less than an average daily dose of five morphine milligram equivalent during the last four weeks prior to delivery. No significant changes in the incidence of NOWS were observed between 2013 and 2018. The odds of neonatal opioid withdrawal syndrome increased significantly as the maternal average daily dose of morphine milligram equivalent during the last four weeks prior to delivery surpassed 40.

Abstract PS13-01: Worse Prognosis for Breast Cancer in the Second and Third Trimesters and Shortly Postpartum:An Update of the Dutch Pregnancy-Associated Breast Cancer Cohort

Abstract Rationale: Pregnancy-Associated Breast Cancer (PABC), often defined as breast cancer during pregnancy (PrBC) or in the first year postpartum (PPBC), is known for its aggressive histopathology and higher stage at diagnosis. In a previous study of the nationwide Dutch PABC Cohort, we observed an impaired survival for patients diagnosed in the second and third trimester of pregnancy. However, the etiology of these differences, and how this relates to the patients diagnosed with breast cancer in the postpartum period (PPBC) or after an abortion (AABC), remains to be elucidated. While we are exploring the etiologic hypotheses, we updated and expanded our database to compare these specific PABC subgroups. Methods: All pathology reports of invasive breast carcinoma between January 1st 1988 and July 1st 2022 were screened for pregnancy-related keywords to find all patients diagnosed with PrBC, PPBC or AABC within one year after childbirth or an interrupted pregnancy (induced abortion or miscarriage before a gestational age of 24 weeks). A local patient series provided 22 additional cases. Pregnant patients were subdivided by gestational trimester at time of diagnosis. The different PrBC, PPBC and AABC subgroups were compared by histopathology, clinical characteristics and outcome. Results: 787 patients were included, of whom 60% were pregnant during their diagnosis. Median age at diagnosis was 34 years. In line with our previous findings, a large majority (68%) of patients had a Bloom &amp; Richardson (B&amp;R) grade III tumor and 37% of tumors were triple negative. Moreover, over a third of patients presented with lymph node metastases (38%). We observed two distinct groups based on histopathology and prognosis: group A, consisting of three patient groups: (I) patients diagnosed in the first trimester of pregnancy, (II) patients diagnosed between 6-12 months postpartum, and (III) patients diagnosed after an abortion, and group B, consisting of two patient groups, (I) patients diagnosed in the second or third trimester of pregnancy or (II) within 6 months after childbirth. Compared to group A, patients in group B more often had B&amp;R grade III tumors: (73% vs. 60%, p=0.002) and more frequently had triple negative tumors (43% vs. 28% in group A, p&amp;lt; 0,001). Survival was significantly worse for patients in group B (5-year OS 67,3% versus 88.2%, p&amp;lt; 0.001). In a multivariable analysis, corrected for grade, type of surgery and overall stage, these differences upheld with an HR of 1.515 (95% CI 1,012 – 2,268). Conclusions: With this extensive update of our nationwide Dutch PABC cohort, we show that especially PrBC patients diagnosed in the second and third trimesters and PPBC patients within six months after childbirth exhibit unfavorable tumor characteristics, with an associated worse prognosis. This highlights the need for in-depth analyses in these specific groups of PABC patients to elucidate the etiologic mechanisms involved.

Pregnancy-Associated Onset of Adult-Onset Still's Disease

Objective: This study aims to elucidate the clinical manifestations, diagnostic challenges, and management strategies of Adult-Onset Still’s Disease (AOSD) during pregnancy, leveraging a case series overview and a detailed case report from our center. Study Design: A comprehensive review of 21 published case reports on AOSD diagnosed during pregnancy was conducted, alongside a detailed case report of a patient diagnosed and managed at our center. This study emphasizes the importance of recognizing AOSD in pregnant patients, outlines the therapeutic challenges encountered, and discusses the potential complications arising from the disease and its treatment. Results: The onset of AOSD during pregnancy predominantly occurs in the first or second trimester, with a polycyclic disease course observed in the majority of cases. Management primarily involves corticosteroids and immunosuppressive medications. The case report highlights the complex interplay between AOSD, Hemophagocytic Lymphohistiocytosis (HLH), and pregnancy, illustrating a multidisciplinary approach to management that ensured favorable maternal and fetal outcomes despite the significant challenges. Conclusion: AOSD presents unique diagnostic and therapeutic challenges during pregnancy, requiring careful consideration of maternal and fetal health. Early diagnosis, a multidisciplinary approach to care, and judicious use of immunosuppressive therapy are critical for managing AOSD flares and associate

Abstract PS13-03: Safety of taxane chemotherapy for the treatment of breast cancer during pregnancy: an international cohort study

Abstract Introduction: The addition of taxanes to anthracycline-based chemotherapy regimens offers increased odds of survival in breast cancer (BC) patients. However, some clinicians defer their use in pregnant patients due to limited evidence supporting safety during gestation. The aim of this study is to describe the prevalence of maternal and neonatal adverse events in BC patients exposed to taxane-containing regimens during pregnancy. Methods: This is an international cohort study of BC patients treated with taxane chemotherapy during pregnancy. Inclusion criteria were age ≥18 years, treatment in a participating center (n=10), and completion of pregnancy. Results: A total of 103 women with a median age of 34 years (range 21-44) were included, of whom the majority (91/101; 90.1%) were also exposed to anthracyclines. The median gestational age at initiation of any chemotherapy agent was 16 weeks (range 4-34), while that of taxanes was 28 weeks (range 12-37). Paclitaxel was the most frequently used taxane (100/103; 97.1%), most prescribed as an 80 mg/m2 weekly infusion. All cases were singleton pregnancies except for one twin gestation. The overall live birth rate was 98.0% (100/102). Median gestational age at delivery was 37 weeks (range 32 to 40), with 36/83 live births being preterm (gestational age of &amp;lt; 37 weeks; 43.4%). Median birth weight was 2700 grams (range 1440-4000). The prevalence of grade 3 to 4 adverse events, obstetric complications, and neonatal outcomes are shown in the Table. A total of 56/58 (96.6%) of neonates had a 5-minute Apgar score ≥7 and 14/88 (15.9%) were admitted to a neonatal intensive care unit. Follow-up beyond the neonatal period was available for 28 neonates (median 42 months, range 1-228), of which reported adverse events were: cardiac abnormality (n=1), speech disorder (n=1), renal disfunction (n=1), and femoral anteversion (n=1). Conclusion: The use of taxane-containing chemotherapy during pregnancy does not seem to increase the risk of obstetric and neonatal complications. Our findings support the use of taxanes during gestation when clinically indicated. Table 1. Reported adverse events with gestational use of taxane-containing chemotherapy regimens.

Severe Bilateral Breast Hypertrophy in a Pregnant Patient: A Case Report

Background: Bilateral breast hypertrophy, ranging from mild to severe, can lead to various complications, including pain, ulceration, infection, and psychological distress. Swift surgical intervention is often necessary to address the mechanical and psychological challenges associated with excessive breast weight. While treatment approaches for this condition are debated, recent advancements favor surgical strategies like mastectomies with reconstruction to improve clinical and psychological outcomes. We present a unique case of bilateral breast hypertrophy successfully managed through breast amputation and NAC (nipple-areolar complex) graft using wise patterns incision mammoplasty. Case Presentation: This report details the case of a 30-year-old female with hypothyroidism and lupus who experienced significant bilateral breast enlargement during her second pregnancy. The patient faced pain, hyperpigmentation, and limited mobility, along with abnormal laboratory findings. Bilateral reduction mammoplasty (breast amputation) was performed, leading to successful outcomes and improved quality of life for both the patient and her newborn. Follow-up assessments showed no recurrence or complications postoperatively. Conclusion:This case highlights the challenges of managing breast hypertrophy in pregnant patients with autoimmune conditions. Early recognition and multidisciplinary management are crucial in such cases. The positive results of the interventions underscore the importance of timely and comprehensive care for patients facing similar conditions.

Acute liver failure in pregnancy.

Liver function abnormalities are noted in a minority of pregnancies with multiple causes for the same. A small proportion of these develop severe liver injury and progress to acute liver failure (ALF). There is a discrete set of etiology for ALF in pregnancy and comprehensive understanding will help in urgent evaluation. Certain diseasessuch as acute fatty liver of pregnancy, hemolysis, elevated liver enzyme, low platelet (HELLP) syndrome and pre-eclampsia are secondary to pregnant state and can present as ALF. Quick and targeted evaluation with urgent institution of etiology-specific management, especially urgent delivery in patients with pregnancy-associated liver diseases, is the key to avoiding maternal deaths. Pregnancy, as also the fetal life, imparts a further layer of complication in assessment, prognosis and management of these sick patients with ALF. Optimal management often requires a multidisciplinary approach in a well-equipped centre. In this review, we discuss evaluation, assessment and management of pregnant patients with ALF, focussing on approach to pregnancy-associated liver diseases.

Pregnancy and Inflammatory Bowel Disease: impact of gestation in a tertiary care center.

Abstract Introduction and objectives: Pregnancy is a relevant milestone in the clinical course of a patient with Inflammatory Bowel Disease (IBD). The objective was to evaluate the impact of adherence to the therapeutic plan in the course of pregnancy and to analyze variables related to disease activity, treatments received and pregnancy outcome. Material and methods: single-center retrospective observational study in pregnant patients with IBD. Demographic variables related to the disease, treatment received and pregnancy outcomes were collected. Adherent group was defined as the group that agreed to the therapeutic plan. A non-adherent group was defined as those patients who did not agree to the therapeutic plan or who abandoned it during pregnancy. Results: 32 patients were included, 56.3% diagnosed with Crohn's disease (CD) and 43.7% with Ulcerative Colitis (UC). Of those diagnosed with CD, 13 were in remission and 5 had moderate activity, compared to 11 in remission and 3 with mild activity in UC. Eleven (34.4%) patients abandoned treatment without consensus, and 12 (37.5%) patients had flares during pregnancy. Significant differences were found with respect to the number of flares and fetal birth weight. Differences were also found when comparing inflammatory activity at the beginning of pregnancy and the evolution of pregnancy. Conclusion:The study data reinforce the importance of preconception counseling, activity control and adherence to the therapeutic plan, motivating us to improve the care and follow-up of our patients of gestational age.

COVID-19-associated morbidity and mortality outcomes in pregnant patients admitted to intensive care unit

Background: Our study aimed to evaluate the clinical characteristics and maternal-fetal outcomes of pregnant women admitted to the ICU due to COVID-19 pneumonia. Materials and Methods: Demographic data, presenting complaints, laboratory values, pregnancy outcomes, delivery method, and ICU mortality were recorded. Results: A total of 10 pregnant patients were admitted to the intensive care unit of our hospital due to SARS-COV-2 infection during the 2-year period. Arterial blood oxygen saturation values measured at admission to the ICU were higher in the surviving patients. Six of the 10 patients died. Only one of the 7 patients requiring invasive mechanical ventilation survived. Conclusions: We found that COVID-19-infected pregnant women with severe symptoms have several maternal morbidities and poor obstetric outcomes, such as prolonged intensive care unit stay, increased mortality, neonatal deaths, and caserean section.

Estimation of maternal and foetal risk of radiation-induced cancer from a survey of computed tomography pulmonary angiography and ventilation/perfusion lung scanning for diagnosing pulmonary embolism during pregnancy.

While there are many papers on maternal and foetal radiation doses from computed tomography pulmonary angiography (CTPA) and ventilation/perfusion (V/Q) lung scanning examinations for diagnosing pulmonary embolism in pregnant patients, few have used clinical data to examine the patient lifetime attributable risk (LAR) of different cancer types. This paper aims to estimate the cancer risk from maternal radiation doses from CTPA and V/Q examinations and associated foetal doses. Dosimetric data were determined for 267 pregnant patients who received CTPA and/or V/Q examinations over 8 years. Organ and foetal doses were determined using software allowing patient size variations for CTPA and using two different activity-to-organ dose conversion methods for V/Q scans. The LAR of cancer incidence was estimated using International Commission on Radiological Protection (ICRP) modelling including estimates of detriment. Estimated total cancer incidence was 23 and 22 cases per 100,000 for CTPA and V/Q examinations, respectively, with detriment estimates of 18 and 20 cases. Cancer incidence was evenly divided between lung and breast cancer for CTPA with lung cancer being 80% of all cancer for V/Q. The median foetal doses were 0.03 mSv for CTPA and 0.29 mSv for V/Q. Significant differences in estimated foetal dose for V/Q scans were obtained by the two different methods used. The differences in dose between the modes of CTPA scan acquisition highlight the importance of optimisation. Maternal cancer incidence and detriment were remarkably similar for each examination. Optimisation of examinations is critical for low-dose outcomes, particularly for CTPA examination.

The effect of bariatric surgery on polycystic ovary syndrome patients' obstetric and neonatal outcomes: a population-based study.

To examine the effect of bariatric surgery (BS) on obstetric and neonatal outcomes in patients with polycystic ovary syndrome (PCOS). A retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project Nationwide Inpatient Sample database, including women who delivered in the third trimester or had a maternal death in the USA (2004-2014). We compared obstetric and neonatal outcomes between groups in three analyses: (1) Primary analysis-women with an ICD-9 PCOS diagnosis who underwent BS compared to pregnant PCOS patients without BS. (2) Sub-group analysis-PCOS women with BS compared to obese PCOS women (body mass index (BMI) ≥ 30 kg/m2) without BS. (3) Women with and without PCOS who underwent BS. In the primary analysis, pregnant PCOS women who underwent BS (N = 141), compared to pregnant PCOS women without BS (N = 14,741), were less likely to develop pregnancy-induced hypertension (PIH) (9.2% vs. 16.2%, respectively, aOR 0.39, 95% CI 0.21-0.72) and gestational diabetes mellitus (GDM) (9.9% vs. 18.8, aOR 0.40, 95% CI 0.23-0.70). In the sub-group analysis, PCOS women with BS, compared to obese PCOS women without BS (N = 3231), were less likely to develop gestational hypertension, preeclampsia, and preeclampsia or eclampsia superimposed on hypertension (P < 0.05). Lastly, PCOS patients with BS had a higher cesarean section rate when compared to non-PCOS patients with BS (N = 9197) (61.7% vs. 49.2%, aOR 1.48, 95% CI 1.05-2.09), with otherwise comparable obstetric and neonatal outcomes. BS in PCOS patients was associated with reduced risks for GDM and PIH when compared to PCOS controls without BS and reduced risk for gestational hypertension, preeclampsia, and preeclampsia or eclampsia superimposed on hypertension when compared to obese PCOS controls without BS. Moreover, BS was associated with reduced inherent pregnancy risks of PCOS, almost equating them to those of non-PCOS counterparts.

Screening for bacterial vaginosis prior to delivery: a cost-effectiveness study.

The objective of this study was to compare the cost and effectiveness of three strategies for screening and/or treating bacterial vaginosis (BV) during pregnancy prior to delivery: (1) the current standard of care, neither test nor treat for BV (Treat None); (2) test all patients for BV at 36 weeks gestation; treat if positive (Test Treat); and (3) treat all patients undergoing cesarean delivery with intravenous metronidazole at time of surgery (Treat All Cesarean). Effectiveness was defined as avoidance of postpartum surgical site infection. A decision analytic cost-effectiveness model was designed from a third-party payer perspective using clinical and cost estimates obtained from the literature, American College of Surgeons National Surgical Quality Improvement Program participant use file, National Vital Statistics, Medicare costs, and wholesale drug costs. Cost estimates were inflated to 2020 United States dollars. For this study, effectiveness was defined as postpartum surgical site infections (SSI) avoided. In the base case analysis, the current standard of care, Treat None, was the most expensive and least effective strategy, with a mean cost of $59.16 and infection rate of 3.71%. Treat All Cesarean was the most effective and least expensive strategy, with a mean cost of $53.50 and an infection rate of 2.75%. Test Treat was also relatively inexpensive and effective, with an infection rate of 2.94% and mean cost of $57.05. Compared to Treat None, we would expect the Treat All Cesarean strategy to reduce the infection rate by 26%. These findings suggest that treating pregnant patients with intravenous metronidazole at time of cesarean delivery could be an effective and cost-saving strategy. Testing and treating for BV could also be considered a reasonable strategy, as it has the added benefit of preserving antibiotic stewardship. In no analysis was the standard of care the preferred strategy.

Test performance and clinical utility of expanded non-invasive prenatal test: Experience on 71,883 unselected routine cases from one single center.

The balance between benefits and risks of discordant outcomes makes the Genome-Wide Non-Invasive Prenatal Test (GW-NIPT) controversial. This study aims to evaluate performance and clinical utility in a wide cohort of unselected clinical cases from a single center when a standardized protocol is applied and integrated with a secondary algorithm for data interpretation. In 2years, over 70,000 pregnant patients underwent GW-NIPT for fetal common trisomies, sex chromosome aneuploidies, rare autosomal aneuploidies, segmental abnormalities (CNVs≥7Mb) and microdeletions (CNVs<7Mb). All samples were uniformly processed with Veriseq NIPT Solution v2 and analyzed using all data metrics along with a home-made algorithm for sequencing data analysis. Results were retrospectively reviewed for clinical outcomes. Among 71,883 eligible cases including twin pregnancies, 1011 (1.4%) received a positive result and 781 were confirmed by invasive prenatal diagnosis. Clinical sensitivity ranged from 99.65% for common trisomy (T21, T18, T13) to 83.33% for microdeletions, while specificity remained high (99.98%) for each class of fetal abnormalities detected. Integrating a standardized protocol with an internal algorithm allowed discordant results to be reduced, yielding high accuracy. Observed reliability in detecting genome-wide chromosomal conditions reinforced the expanded NIPT utility in clinical practice.

Provider-patient relationships and trauma among pregnant patients with opioid-use disorder.

The provider-patient relationship is integral to medical practice and health outcomes, particularly among vulnerable patient populations. This study compared the provider-patient relationship among pregnant patients with opioid-use disorder (OUD), who did or did not have a history of moderate to severe trauma. This was an exploratory data analysis of 119 patients enrolled in the Support Models for Addiction Related Treatment trial. Probable posttraumatic stress disorder (PTSD) was determined by a score ≥ 31 on the PTSD Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. The provider-patient relationship was assessed at 26 ± 4 weeks of pregnancy using the Kim Alliance Scale (KAS). Multivariable regression was used to examine the association of KAS with probable PTSD among pregnant people with OUD. The mean KAS score for pregnant participants without probable PTSD (N = 88) was 61.4 (SD ± 2.8) and for pregnant participants with probable PTSD (N = 31) was 59.6 (SD ± 3.7). Results demonstrated significant differences in KAS scores between those with and without probable PTSD after adjusting for demographic variables. Adjusted mean total KAS scores and scores on Empowerment and Communication subscales were significantly lower among those with probable PTSD compared to those without (p = .04 and 0.02, respectively) but did not differ significantly on Collaboration and Integration subscales. Analyses show an association between probable PTSD and provider-patient relationship among pregnant patients with OUD, with those with probable PTSD having a worse alliance with obstetric providers. This novel finding helps characterize the provider-patient relationship among a uniquely vulnerable population and can inform efforts to integrate trauma-informed practices into prenatal care.

The role of autoimmune thyroid disorders in patients with alopecia areata

Objective: The aim of this study was to investigate the association of thyroid autoimmunity with alopecia areata (AA) by examining thyroid stimulating hormone (TSH) and thyroid autoantibody levels. In addition, to compare the epidemiologic data obtained with the data of our country. Methods: Our study was organized as a cross-sectional, retrospective study. The study was performed on patients between the ages of 2-65 years who were admitted to our outpatient clinic between 01.01.2008 and 31.12.2011, who were clinically or histopathological diagnosed with AA, examined for etiology and thyroid autoantibodies were requested. Patients under two years of age and over 65 years of age, patients with no thyroid autoantibodies and pregnant patients were excluded. Results were expressed as mean±standard deviation and median values. Mann-Whitney U test was used to compare TSH, anti-TG antibody (Anti-TG) and anti-TPO (Anti-TPO) antibody values in the variables of nail involvement, psychiatry, comorbidity and family history. Spearman correlation analysis was used to examine the relationships between age and disease duration and TSH, Anti-TPO and Anti-TG variables. Results: In our study, 65 (42.8%) of 152 patients were female and 87 (57.2%) were male. The ages of the patients ranged between 2-65 years and the mean age was 26.5±14.6 years. The mean age of females was 27.5±14.4 and 25.7±14.9 in males. Elevated thyroid autoantibodies were found in a total of 29 patients, 21 of whom were female and 8 of whom were male. Of these 29 patients, 10 had hypothyroidism, 2 had chronic thyroiditis and 3 had toxic multinodular goiter. 14 patients did not return after the examination at the internal medicine outpatient clinic, so the diagnosis of thyroid disease could not be reached. The mean TSH, Anti-TG and Anti-TPO values were 2.27±1.57, 29.2±99 and 71.5±2.2, respectively. When these values were analyzed separately as men and women, they were found to be 2.6±2.02, 41.8±1.23 and 134±2.8 in women and 1.99±1.03, 19.8±75.6 and 24.5±1.32 in men. There was a significant difference between men and women in terms of Anti-TG and Anti-TPO values (p=0.011 and p=0.001, respectively). A significant correlation was found between disease duration and Anti-TPO positivity (p=0.045); however, a similar relationship was not found between disease duration and Anti-TG positivity (p=0.34). Conclusions: As a result of this study, although there was a significant correlation between anti-TPO and duration of AA, the association between thyroid autoimmunity and AA was not found to be statistically significant. This may be due to the fact that humoral autoimmunity plays a role in thyroid autoimmunity and primarily cellular autoimmunity plays a role in AA. In addition, the epidemiologic data of our study were similar to the data of studies conducted in our country.

Use of Electronic Patient Messaging by Pregnant Patients Receiving Prenatal Care at an Academic Health System: Retrospective Cohort Study.

The COVID-19 pandemic accelerated telemedicine and mobile app use, potentially changing our historic model of maternity care. MyChart is a widely adopted mobile app used in health care settings specifically for its role in facilitating communication between health care providers and patients with its messaging function in a secure patient portal. However, previous studies analyzing portal use in obstetric populations have demonstrated significant sociodemographic disparities in portal enrollment and messaging, specifically showing that patients who have a low income and are non-Hispanic Black, Hispanic, and uninsured are less likely to use patient portals. The study aimed to estimate changes in patient portal use and intensity in prenatal care before and during the pandemic period and to identify sociodemographic and clinical disparities that continued during the pandemic. This retrospective cohort study used electronic medical record (EMR) and administrative data from our health system's Enterprise Data Warehouse. Records were obtained for the first pregnancy episode of all patients who received antenatal care at 8 academically affiliated practices and delivered at a large urban academic medical center from January 1, 2018, to July 22, 2021, in Chicago, Illinois. All patients were aged 18 years or older and attended ≥3 clinical encounters during pregnancy at the practices that used the EMR portal. Patients were categorized by the number of secure messages sent during pregnancy as nonusers or as infrequent (≤5 messages), moderate (6-14 messages), or frequent (≥15 messages) users. Monthly portal use and intensity rates were computed over 43 months from 2018 to 2021 before, during, and after the COVID-19 pandemic shutdown. A logistic regression model was estimated to identify patient sociodemographic and clinical subgroups with the highest portal nonuse. Among 12,380 patients, 2681 (21.7%) never used the portal, and 2680 (21.6%), 3754 (30.3%), and 3265 (26.4%) were infrequent, moderate, and frequent users, respectively. Portal use and intensity increased significantly over the study period, particularly after the pandemic. The number of nonusing patients decreased between 2018 and 2021, from 996 of 3522 (28.3%) in 2018 to only 227 of 1743 (13%) in the first 7 months of 2021. Conversely, the number of patients with 15 or more messages doubled, from 642 of 3522 (18.2%) in 2018 to 654 of 1743 (37.5%) in 2021. The youngest patients, non-Hispanic Black and Hispanic patients, and, particularly, non-English-speaking patients had significantly higher odds of continued nonuse. Patients with preexisting comorbidities, hypertensive disorders of pregnancy, diabetes, and a history of mental health conditions were all significantly associated with higher portal use and intensity. Reducing disparities in messaging use will require outreach and assistance to low-use patient groups, including education addressing health literacy and encouraging appropriate and effective use of messaging.
