Zhang M, Wei R, Jing J, Huang S, Qiu G, Xia X, Zhang Y, Li Y. Subsequent maternal sleep deprivation aggravates cognitive impairment by modulating hippocampal neuroinflammatory responses and synaptic function in maternal isoflurane-exposed offspring mice. Brain Behav 2024; 14:e3610. [PMID: 38945806 PMCID: PMC11214875 DOI: 10.1002/brb3.3610] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 05/29/2024] [Accepted: 06/11/2024] [Indexed: 07/02/2024] Open
Abstract
INTRODUCTION Pregnant women may need to undergo non-obstetric surgery under general anesthesia owing to medical needs, and pregnant women frequently experience sleep disturbances during late gestation. Preclinical studies demonstrated that maternal isoflurane exposure (MISO) or maternal sleep deprivation (MSD) contributed to cognitive impairments in offspring. Research studies in mice have revealed that SD can aggravate isoflurane-induced cognitive deficits. However, it remains unclear whether MSD aggravates MISO-induced cognitive deficits in offspring. The purpose of this research was to explore the combined effects of MSD and MISO on offspring cognitive function and the role of neuroinflammation and synaptic function in the process of MSD + MISO. METHODS Pregnant mice were exposed to 1.4% isoflurane by inhalation for 4 h on gestational day (GD) 14. Dams were then subjected to SD for 6 h (12:00-18:00 h) during GD15-21. At 3 months of age, the offspring mice were subjected to the Morris water maze test to assess cognitive function. Then the levels of inflammatory and anti-inflammatory markers and synaptic function-related proteins were assessed using molecular biology methods. RESULTS The results of this study demonstrated that MISO led to cognitive dysfunction, an effect that was aggravated by MSD. In addition, MSD exacerbated the maternal isoflurane inhalation, leading to an enhancement in the expression levels of interleukin (IL)-1β, IL-6, and tumor necrosis factor-alpha and a reduction in the hippocampal levels of IL-10, synaptophysin, post-synaptic density-95, growth-associated protein-43, and brain-derived neurotrophic factor. CONCLUSION Our findings revealed that MSD aggravated the cognitive deficits induced by MISO in male offspring mice, and these results were associated with neuroinflammation and alternations in synaptic function.

Souza C, Caetano E, Rodrigues S, Lopes M, Mattos B, Santos M, Rizzi E, Dias-Junior C. Isoflurane increases the activity of the vascular matrix metalloproteinase-2 in non-pregnant rats and increases the nitric oxide metabolites in pregnancy. Biosci Rep 2024; 44:BSR20240192. [PMID: 38757914 PMCID: PMC11147811 DOI: 10.1042/bsr20240192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2024] [Revised: 05/08/2024] [Accepted: 05/16/2024] [Indexed: 05/18/2024] Open
Abstract
Surgeries that require general anesthesia occur in 1.5-2% of gestations. Isoflurane is frequently used because of its lower possibility of affecting fetal growth. Therefore, we examined the isoflurane anesthesia-induced effects on maternal hemodynamic and vascular changes. We hypothesized that isoflurane would enhance endothelium-dependent vasodilation as a consequence of increased nitric oxide and decreased metalloproteinases (MMPs). Female rats (n=28) were randomized into 4 groups (7 rats/group): conscious (non-anesthetized) non-pregnant group, non-pregnant anesthetized group, conscious pregnant group, and pregnant anesthetized group. Anesthesia was performed on the 20th pregnancy day, and hemodynamic parameters were monitored. Nitric oxide metabolites, gelatinolytic activity of MMP-2 and MMP-9, and the vascular function were assessed. Isoflurane caused no significant hemodynamic changes in pregnant compared with non-pregnant anesthetized group. Impaired acetylcholine-induced relaxations were observed only in conscious non-pregnant group (by approximately 62%) versus 81% for other groups. Phenylephrine-induced contractions were greater in endothelium-removed aorta segments of both pregnant groups (with or without isoflurane) compared with non-pregnant groups. Higher nitric oxide metabolites were observed in anesthetized pregnant in comparison with the other groups. Reductions in the 75 kDa activity and concomitant increases in 64 kDa MMP-2 isoforms were observed in aortas of pregnant anesthetized (or not) groups compared with conscious non-pregnant group. Isoflurane anesthesia shows stable effects on hemodynamic parameters and normal MMP-2 activation in pregnancy. Furthermore, there were increases in nitric oxide bioavailability, suggesting that isoflurane provides protective actions to the endothelium in pregnancy.

Abstract
Cutaneous malignant melanoma is one of the most common neoplasms among pregnancy-associated cancers (PACs). Risk factors include excessive exposure to ultraviolet radiation, the presence of benign and dysplastic nevi, and a patient or family history of melanoma. Self-examination and careful inspection of nevi are crucial, especially in the context of their progression over time. Physiological changes that occur during pregnancy, such as the darkening and enlargement of the nevi, delay the diagnosis of CMM. In the fetus, metastases are very rare, and if they do occur, they concern the placenta or fetal tissues. The choice of treatment is influenced by the cancer stage, symptoms, the time of termination of pregnancy, and the patient's decision. Essential procedures which are safe for the fetus are diagnostic biopsy, ultrasound, and the therapeutic excision of the lesion and the affected lymph nodes. Other imaging methods can be used with a safe radiation dose limit of 100 mGy. Immunotherapy and targeted treatments must be carefully considered, because of their possible adverse effects on the fetus. An interdisciplinary approach to the problem of melanoma during pregnancy is necessary, involving doctors of various specialties.

Abstract
Background Approximately 1-2% of pregnant women undergo non-obstetric surgery under anaesthesia during their pregnancy. This review specifically targets anaesthesia management for pregnant women undergoing non-obstetric surgery in resource-limited settings. Methods Following the delineation of primary questions, scope, and inclusion criteria, a comprehensive search strategy utilizing advanced techniques was implemented across electronic sources, databases, and websites to identify relevant articles. A rigorous screening process was applied during the literature evaluation. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement guided the conduct of this review, ensuring adherence to standardized reporting practices. Results A total of 240 articles were initially identified from databases and websites. After screening titles and abstracts, 85 papers were excluded, and an additional 43 were removed due to duplication. Subsequently, 68 items were subjected to eligibility screening. Finally, 30 papers that specifically addressed anaesthetic considerations for pregnant women undergoing non-obstetric operations were reviewed. Conclusion Thorough preoperative evaluation is essential for all patients, with particular attention to modifications in anaesthetic management to accommodate physiological changes during pregnancy. Urgent and emergent surgeries should proceed promptly during pregnancy to optimize outcomes for both the mother and foetus. Maintaining uteroplacental perfusion generally involves avoiding maternal hypoxaemia, hypotension, hyper- and hypocapnia, temperature extremes, and stress. When deemed safe, regional anaesthesia may offer favourable outcomes for both the mother and foetus.

Abstract
PURPOSE OF REVIEW Nonobstetric surgery during pregnancy is associated with maternal and fetal risks. Several physiologic changes create unique challenges for anesthesiologists. This review highlights physiologic changes of pregnancy and presents clinical recommendations based on recent literature to guide anesthetic management for the pregnant patient undergoing nonobstetric surgery. RECENT FINDINGS Nearly every anesthetic technique has been safely used in pregnant patients. Although it is difficult to eliminate confounding factors, exposure to anesthetics could endanger fetal brain development. Perioperative fetal monitoring decisions require an obstetric consult based on anticipated maternal and fetal concerns. Given the limitations of fasting guidelines, bedside gastric ultrasound is useful in assessing aspiration risk in pregnant patients. Although there is concern about appropriateness of sugammadex for neuromuscular blockade reversal due its binding to progesterone, preliminary literature supports its safety. SUMMARY These recommendations will equip anesthesiologists to provide safe care for the pregnant patient and fetus undergoing nonobstetric surgery.

Abstract
INTRODUCTION Trauma during pregnancy deserves special attention as management must be directed towards both the mother and the fetus. Management of maxillofacial fractures in pregnancy can adversely affect the well-being of the fetus by impinging on normal functions such as respiration, mastication, and nutrition. Pregnancy complicates the management of facial injury due to the maintenance of the patent airway, anesthesia considerations, and imaging restraints. The purpose of this study is to use three illustrative from our own institution to further elucidate education on the management of mandible fracture in pregnancy with a focus on multidisciplinary treatment and outcomes. METHODS A retrospective chart review was performed for all cases of facial fractures admitted to Ryder Trauma Center from 2012 to 2022. During this time, 4,910 patients presented with facial fractures 1319 patients were female. Three of the patients were pregnant at the time of admission. Demographics, mechanism of injury, associated injuries, and management information were collected. RESULTS Patient 1 was a 20-year-old female presented to Ryder Trauma Center following a motor vehicle collision. She was 17 weeks pregnant at the time of admission and was found to have a left mandibular angle fracture. Patient 2 was a 14-year-old female who presented to Ryder Trauma Center status post gunshot wound to the mandible after she and her brother were unknowingly playing with a loaded gun. She was 18 weeks pregnant at the time of admission, with a past medical history of domestic violence, suicidal ideation, and major depressive disorder. Patient 3 was a 20-year-old female 36 weeks pregnant at the time of admission. She presented with a right paraymphyseal fracture and left mandibular angle fracture as a result of falling on the stairs. Patients all underwent surgical repair of fractures.

Abstract
INTRODUCTION For women presenting with breast cancer during pregnancy, treatment guidelines were historically restricted to only surgical treatment. Over the past decades, chemotherapy administered during pregnancy has been gradually introduced. Although breast cancer treatments during ongoing pregnancy have been deemed safe, detailed information on potential obstetric risks is lacking. We aimed to assess the risk of adverse obstetric and perinatal outcomes of breast cancer in pregnancy and within 1 year postpartum and in relation to trimester at breast cancer diagnosis, tumor stage, and cancer treatment during pregnancy. MATERIAL AND METHODS Population-based matched study. Women diagnosed with breast cancer during pregnancy in 1973-2017 were identified in the Swedish Cancer Register and the Medical Birth Register, with additional information from the National Quality Register for Breast Cancer. Each birth with maternal breast cancer (n = 208 pregnant, n = 672 postpartum) was matched by age, calendar year, and birth order to 10 unexposed births from cancer-free women in the population (n = 2080 and n = 6720). Adjusted conditional logistic and multinomial regression models were used to estimate odds ratios and relative risk ratios, commonly denoted relative risks (RR) with 95% confidence intervals (CI), of adverse obstetric and perinatal outcomes. RESULTS Breast cancer during pregnancy was associated with higher risks of preterm birth, both planned (RR 67.1, 95% CI 33.2-135.6) and spontaneous preterm birth (RR 3.8, 95% CI 2.0-7.5), and low birthweight (<2500 g: RR 7.5, 95% CI 4.9-11.3). The associated risks were higher if the breast cancer was diagnosed in the second trimester, and of similar magnitude irrespective of stage and treatment groups. There was a higher risk of low birthweight for gestational age (<25th centile) if breast cancer was diagnosed in the first trimester (RR 2.8, 95% CI 1.1-7.3). Risks of other pregnancy complications were similar to those of unexposed women, as were risks of neonatal mortality and malformations. Postpartum breast cancer was only associated with bleeding during pregnancy (RR 1.6, 95% CI 1.0-2.8). CONCLUSIONS Preterm birth and related adverse outcomes were more common in women diagnosed with breast cancer during pregnancy. Reassuringly, breast cancer was not associated with other maternal pregnancy complications or adverse outcomes in children.

Abstract
Fetal heart rate monitoring during general anesthesia for non-obstetric surgery at viable gestational ages is recommended to evaluate fetal well-being during the intervention. Alteration induced by anesthetic drugs could mimic fetal acute hypoxia, leading to pointless Cesarean sections. We report a case of a pregnant woman in the third trimester undergoing neurosurgical surgery. The continuous heart rate registration showed a non-reassuring pattern, potentially inducing the multidisciplinary team to expedite the delivery. The seriate fetoplacental Doppler evaluations were reassuring about normal fetal conditions, suggesting that ultrasound surveillance could be more reliable than intraoperative heart rate monitoring.

Abstract
Nonobstetrical surgical emergencies can occur throughout pregnancy but are often difficult to diagnose due to the physiologic and anatomical changes that occur during pregnancy. Medical providers should have insight into these changes and be familiar with options for the diagnosis and management of common nonobstetrical surgical emergencies, such as appendicitis, cholecystitis, and small bowel obstruction. Surgeons should also be aware of obstetrical emergencies, such as ectopic pregnancy and severe vaginal bleeding, which may be life threatening to mother and the fetus. Intraoperatively, surgeons should be familiar with minimally invasive approaches for surgical diseases and special anesthetic considerations for pregnant patients.

Abstract
Patients with a clinical indication for aortic valve replacement can either undergo surgical aortic valve replacement (SAVR) or Transcatheter Aortic Valve Implantation (TAVI). There are many different factors that go into determining which type of replacement to undergo, including age, life expectancy, comorbidities, frailty, and patient preference. While both options offer significant benefits to patients in terms of clinical outcomes and quality of life, there is growing interest in expanding the indications for TAVI due to its minimally invasive approach. However, it is worth noting that there are several discrepancies in TAVI outcomes in regards to various endpoints, including death, stroke, and major cardiovascular events. It is unclear why these discrepancies exist, but potential explanations include the diversity of etiologies for aortic stenosis, complex patient comorbidities, and ongoing advancements in both medical therapies and devices. Of these possibilities, we propose that phenotypic variation of aortic stenosis has the most significant impact on post-TAVI clinical outcomes. Such variability in phenotypes is often due to a complex interplay between underlying comorbidities and environmental and inherent patient risk factors. However, there is growing evidence to suggest that patient genetics may also play a role in aortic stenosis pathology. As such, we propose that the selection and management of TAVI patients should emphasize a precision medicine approach.

Wonte MM, Bantie AT, Tadesse M. A pregnant lady with compound bowel obstruction managed with thoracic epidural as sole anesthesia in a resource-restricted setting: a case report. J Med Case Rep 2023; 17:231. [PMID: 37271824 DOI: 10.1186/s13256-023-03962-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2023] [Accepted: 04/26/2023] [Indexed: 06/06/2023] Open
Abstract
BACKGROUND Preserving the mother's safety, sustaining the pregnancy state, and achieving the optimal fetal outcome are the major priorities when managing obstetric patients for non-obstetric surgery. Only necessary and urgent surgeries are carried out during pregnancy due to the effects of anesthesia and surgery on the fetus. Compound bowel obstruction (small and large bowel obstruction) is rare, especially during the third trimester of pregnancy. Besides this, the procedure (laparotomy) was done with awake opioid-based thoracic epidural anesthesia as the sole anesthesia. This case report of awake laparotomy for major abdominal surgery is the first of its kind with an excellent feto-maternal outcome. CASE PRESENTATION A 30-year-old African pregnant lady presented to the emergency department with a chief complaint of abdominal pain and vomiting for an 8-hour duration; associated with this, she had a history of blurred vision, lightheadedness, loss of appetite, low-grade fever, and constipation. Later, she was diagnosed with large bowel obstruction and underwent an emergency laparotomy, managed with a thoracic epidural sole anesthesia. CONCLUSION A multidisciplinary team approach is greatly recommended to safeguard a sufficient standard of care for both the mother and fetus. The provision of regional anesthesia for patients with high risks in perioperative periods is crucial for a better postoperative outcome. We have confidence that thoracic epidural anesthesia can be used as another anesthetic option for major abdominal surgery in a resource-restricted setting for patients who are expected to have a significant risk of perioperative adverse events under general anesthesia.

Abstract
The management of cancer during pregnancy requires a patient-centered, multidisciplinary approach to balance maternal and fetal well-being given the rarity of this clinical scenario and lack of substantial data. Involvement of oncology and nononcology medical specialists and ethical, legal, and psychosocial supports, as needed, is instrumental in navigating the complexities of care for this patient population. Critical periods of fetal development and physiological changes in pregnancy must be considered when planning diagnostic and therapeutic approaches during pregnancy. The complexity of symptom recognition and interventional approaches contributes to diagnostic delays of cancers during pregnancy. Ultrasound and whole-body diffusion-weighted magnetic resonance imaging are safe throughout pregnancy. Surgery can be safely performed throughout pregnancy, with the early second trimester preferred for intra-abdominal surgery. Chemotherapy can be safely administered after 12-14 weeks of gestation until 1-3 weeks before the anticipated delivery. Most targeted and immunotherapeutic agents are contraindicated during pregnancy because of limited data. Pelvic radiation during pregnancy is absolutely contraindicated, while if radiation to the upper body is needed, administration should only be considered early in pregnancy. To ensure that the total cumulative fetal exposure to ionizing radiation does not exceed 100 mGy, early inclusion of the radiology team in the care plan is required. Closer prenatal monitoring is recommended for maternal and fetal treatment-related toxicities. Delivery before 37 weeks of gestation should be avoided if possible, and vaginal delivery is preferred unless obstetrically indicated or specific clinical scenarios. Postpartum, breastfeeding should be discussed, and the neonate should receive blood work to assess for acute toxicities with follow-up arranged for long-term monitoring.

Abstract
BACKGROUND Although intrathecal ropivacaine has been widely used for caesarean delivery, there are limited data for the use of ropivacaine for prophylactic cervical cerclage. We sought to determine the median effective dose of intrathecal ropivacaine for prophylactic cervical cerclage in 50% of patients (ED50) and the calculated dose required for successful block in 95% of patients (ED95). METHODS We included Chinese women scheduled for prophylactic cervical cerclage under combined spinal-epidural (CSE) anaesthesia in the first or second trimester. A predetermined dose of intrathecal isobaric ropivacaine was administered. If this determined dose achieved an effective block at a level not lower than T12, the next dose was decreased by 0.5 mg. Otherwise, the next dose was increased by 0.5 mg. The primary outcome was the ED50 of intrathecal ropivacaine. Secondary outcomes included the calculated ED95, time from CSE to the start of surgery and so on. RESULTS Forty patients were included in the study, 23 (57.5%) of 40 received an effective block only with intrathecal ropivacaine, while 17 (42.5%) patients needed extra epidural lidocaine to achieve a successful block. The ED50 of intrathecal ropivacaine confirmed by isotonic regression was 6.9 mg (95% CI, 6.68 to 7.12 mg), and the calculated ED95 was 7.8 mg (95% CI, 7.69 to 10.05 mg). When an effective block was achieved with intrathecal ropivacaine alone, the time to resolution of the sensory and motor blocks was 90 (75-100) min and 90 (60-100) min, respectively. CONCLUSIONS The ED50 of intrathecal ropivacaine for prophylactic cervical cerclage was 6.9 mg. Intrathecal ropivacaine (7.8 mg) is likely to produce successful anaesthesia in 95% of patients undergoing prophylactic cervical cerclage. TRIAL REGISTRATION NUMBER ChiCTR2100051418.

Abstract
While it is common for pregnant women to take anesthesia during surgery, the effects of prenatal anesthesia exposure (PAE) on the long-term neurodevelopment of the offspring remain to be clarified. Preclinical animal research has shown that in utero anesthetic exposure causes neurotoxicity in newborns, which is mainly characterized by histomorphological changes and altered learning and memory abilities. Regional birth cohort studies that are based on databases are currently the most convenient and popular types of clinical studies. Specialized questionnaires and scales are usually employed in these studies for the screening and diagnosis of neurodevelopmental disorders in the offspring. The time intervals between the intrauterine exposure and the onset of developmental outcomes often vary over several years and accommodate a large number of confounding factors, which have an even greater impact on the neurodevelopment of the offspring than prenatal anesthesia itself. This narrative review summarized the progress in prenatal anesthetic exposure and neurodevelopmental outcomes in the offspring from animal experimental research and clinical studies and provided a brief introduction to assess the neurodevelopment in children and potential confounding factors.

Abstract
RATIONALE There is no clear consensus guidance for anesthesiologists on how to manage patients with cerebral arteriovenous malformation (cAVM) rupture and hemorrhage during pregnancy who need craniotomy. Our objective was to review the anesthesia management of pregnant women who underwent resection of cAVM at our institution and to provide opinions and suggestions. PATIENT CONCERNS Herein, we report of 3 patients with cAVM rupture and hemorrhage during pregnancy who underwent neurosurgery at the 22nd, 28th, and 20th weeks of pregnancy. DIAGNOSES All 3 patients were admitted to the emergency department of our hospital due to sudden symptoms. Subsequently, their head imaging results confirmed the rupture and hemorrhage of cAVM. The rupture and hemorrhage of cAVM during pregnancy has a low incidence and high mortality, which seriously endangers the safety of the mother and fetus. For this emergency condition, craniotomy for removing intracranial lesions and clear hematoma can result in a chance of a successful delivery. Especially in the second and third trimesters of pregnancy, the management goal of anesthesia is to ensure the maternofetal safety and to maintain continuous pregnancy. INTERVENTIONS This article describes the process of intraoperative anesthesia management and maternal-fetal outcomes and discusses the key issues for the anesthesia management of cAVM rupture during pregnancy, including considerations of physiological changes during pregnancy and anesthesia medication, intraoperative monitoring, the maintenance of hemodynamic stability, and the control of intracranial pressure, among other considerations. Resection of intracranial lesions should be performed whenever possible while maintaining the pregnancy for better maternal and infant outcomes. OUTCOMES The operations of the 3 pregnant women were successfully completed under our detailed anesthesia planning and careful anesthesia management. All the patients recovered well after the operation, and underwent cesarean section to give birth smoothly. LESSONS The preservation of pregnancy under cAVM resection is a complex challenge for anesthesiologists, and these 3 cases provide an extensive amount of experience for anesthesia management in similar situations. Detailed anesthesia planning and careful anesthesia management by anesthesiologists are important guarantees for good maternal and fetal outcomes.

J Oral Maxillofac Surg 2023; 81:150-155. [PMID: 36462536 DOI: 10.1016/j.joms.2022.11.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Revised: 11/07/2022] [Accepted: 11/07/2022] [Indexed: 12/03/2022]
Abstract
PURPOSE Human chorionic gonadotropin (hCG) testing is performed prior to surgical procedures to ensure patient and fetal safety. The purpose of this study was to evaluate the utility of routine pregnancy testing prior to elective outpatient oral and maxillofacial surgery procedures being performed with intravenous sedation (IVS). METHODS A retrospective cohort study was implemented assessing hCG testing in postmenarche females who underwent elective outpatient oral surgery procedures scheduled with IVS at a tertiary care institution. Medical records were used to identify eligible subjects aged 12 to 45 years. The primary predictor variable was age, and the primary outcome variable was urine hCG test result. Age was divided into groups to reflect early adolescence (12 to 14 years), mid-adolescence (15 to 17 years), late adolescence/early adulthood (18 to 24 years) and adulthood (25+ years). Secondary outcome variables included inability to void for hCG testing, change in anesthetic, case cancellation or rescheduling and were measured over a 2 year period. Descriptive statistics were performed. Relative risk (RR) and Cochran-Armitage test for trend were calculated to determine the statistical significance of age on inability to void. RESULTS The sample consisted of 5,006 females, with a median age (IQR, range) of 18.0 (3.6, 12.0 to 43.6) years. There was one positive urine hCG result providing a preoperative pregnancy rate of 0.02%. Fourteen of 1,195 subjects (1.2%) over a 2 year period were unable to provide a urine hCG sample. There was a statistically significant trend in inability to void as age groups got older (P = .001). Patients aged 12 to 17 years had an increased risk of being unable to void compared to patients 18 years and older (RR: 14.30, 95% CI: 1.88 to 108.99, P = .01). The total cost of testing over the 11 year observation period was $9,019.59. CONCLUSIONS The risk of surgical cancellations and delayed care due to patients' inability to void preoperatively plus a lack of any positive preoperative urine hCG findings in patients under 18 years of age in this study, call into question the necessity of routine preoperative hCG screening in pediatric patients presenting for IVS for elective outpatient oral and maxillofacial procedures.

Abstract
Sevoflurane is widely used for maternal anesthesia during pregnancy. Sevoflurane exposure of rats at mid-gestation can cause abnormal development of the central nervous system in their offspring. Sevoflurane is known to increase the expression of cannabinoid 1 receptor (CB1R) in the hippocampus. However, the effect of cannabinoid 1 receptor on fetal and offspring rats after maternal anesthesia is still unclear. At gestational day 14, pregnant rats were subjected to 2-h exposure to 3.5% sevoflurane or air. Rats underwent intraperitoneal injection with saline or rimonabant (1 mg/kg) 30 min prior to sevoflurane or air exposure. cannabinoid 1 receptor, cyclin-dependent kinase 5 (CDK5), p35, p25, tau, and p-tau expression in fetal brains was measured at 6, 12, and 24 h post-sevoflurane/air exposure. Neurobehavioral and Morris water maze tests were performed postnatal days 3-33. The expression of cannabinoid 1 receptor/cyclin-dependent kinase 5/p-tau and histopathological staining of brain tissues in offspring rats was observed. We found that a single exposure to sevoflurane upregulated the activity of cyclin-dependent kinase 5 and the level of p-tau via cannabinoid 1 receptor. This was accompanied by the diminished number of neurons and dendritic spines in hippocampal CA1 regions. Finally, these effects induced lower scores and platform crossing times in behavioral tests. The present study suggests that a single exposure to 3.5% sevoflurane of rats at mid-gestation impairs neurobehavioral abilities and cognitive memory in offspring. cannabinoid 1 receptor is a possible target for the amelioration of postnatal neurobehavioral ability and cognitive memory impairments induced by maternal anesthesia.

Abstract
PURPOSE The management of brain tumors during pregnancy is challenging. The clinical rarity and prognostic heterogeneity of such condition makes it difficult to develop standardized guidelines of treatment. The aim of this study was to assess the treatment options used in pregnant women with brain tumors that are currently used in Italy, considering the management of these patients reported in current literature in this field. METHODS A survey addressing the treatments options and management of brain tumors during pregnancy was designed on behalf of an ad-hoc task-force Neuro-Oncology committee of the Società Italiana di Neurochirurgia (SINch) to analyze the management of pregnant patients with brain tumors. We conducted a search of the literature published between January 2011 and September 2021, using MEDLINE (PubMed) in accordance to PRISMA guidelines. Data were discussed to obtain recommendations after evaluation of the selected articles and discussion among the experts. RESULTS A total of 18 Neurosurgical centers participated in the survey. A total of 31 pregnant women were included in this retrospective study. Meningiomas and gliomas were the two most common types of brain tumors diagnosed during pregnancy. An emergency surgical procedure was required in 12.9% of cases. CONCLUSION A multidisciplinary and tailored approach is fundamental. In women showing clinical stability, neurosurgical options should preferably be delayed if possible, and considered during the second trimester or after delivery. In patients with acute neurological symptoms or tumor progression, medical abortion in the first trimester or a C-section in the second and third trimester need to be considered.

Abstract
BACKGROUND A substantial number of pregnant women require anaesthesia for non-obstetric surgery, but the risk to fetal heart development is unknown. We assessed the relationship between first trimester anaesthesia and risk of congenital heart defects in offspring. METHODS We conducted a longitudinal cohort study of 2 095 300 pregnancies resulting in live births in hospitals of Quebec, Canada, between 1990 and 2016. We identified women who received general or local/regional anaesthesia in the first trimester, including anaesthesia between 3 and 8 weeks post-conception, the critical weeks of fetal cardiogenesis. The main outcome measures were critical and non-critical heart defects in offspring. We estimated risk ratios (RR) and 95% confidence intervals (CI) for the association of first trimester anaesthesia with congenital heart defects, using log-binomial regression models adjusted for maternal characteristics. RESULTS There were 107.3 congenital heart defects per 10 000 infants exposed to anaesthesia, compared with 87.2 per 10 000 unexposed infants. Anaesthesia between 3 and 8 weeks post-conception was associated with 1.50 times the risk of congenital heart defects (95% CI 1.11-2.03), compared with no anaesthesia. Anaesthesia between 5 and 6 weeks post-conception was associated with 1.84 times the risk (95% CI 1.10-3.08). Associations were driven mostly by general anaesthesia, which was associated with 2.49 times the risk between weeks 5 and 6 post-conception (95% CI 1.40-4.44). CONCLUSIONS General anaesthesia during critical periods of fetal heart development may increase the risk of congenital heart defects. Further research is needed to confirm that anaesthetic agents are cardiac teratogens.

Fu PH, Yu CH, Chen YC, Chu CC, Chen JY, Liang FW. Risk of adverse fetal outcomes following nonobstetric surgery during gestation: a nationwide population-based analysis. BMC Pregnancy Childbirth 2022; 22:406. [PMID: 35562679 PMCID: PMC9102935 DOI: 10.1186/s12884-022-04732-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Accepted: 04/18/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Literature suggests that nonobstetric surgery during gestation is associated with a higher risk of spontaneous abortion, prematurity, and a higher cesarean section rate, but the direct impact on fetal outcomes is still unclear. In this study, we aimed to investigate whether nonobstetric surgery during pregnancy is associated with negative fetal outcomes by analysing a nation-wide database in Taiwan. METHODS This population-based retrospective observational case-control study was based on the linkage of Taiwan's National Health Insurance Research Database, Birth Reporting Database, and Maternal and Child Health Database between 2004 and 2014. For every pregnancy with nonobstetric surgery during gestation, four controls were randomly matched according to maternal age and delivery year. We estimated adjusted odds ratios (aOR) and 95% confidence intervals (CIs) of adverse fetal outcomes with the non-surgery group as the reference. The primary outcomes involved stillbirth, prematurity, low birth weight, low Apgar scores, and neonatal and infant death. RESULTS Among 23,721 identified pregnancies, 4,747 underwent nonobstetric surgery. Pregnancies with nonobstetric surgery had significantly higher risks of prematurity (aOR: 1.46; 95% CI: 1.31-1.62), lower birth weight (aOR: 1.49; 95% CI: 1.33-1.67), Apgar scores < 7 (1 min, aOR: 1.58; 95% CI: 1.33-1.86; 5 min, aOR: 1.34; 95% CI: 1.03-1.74), neonatal death (aOR: 2.01; 95% CI: 1.18-3.42), and infant death (aOR: 1.69; 95% CI: 1.12-2.54) than those without nonobstetric surgery after adjustment for socioeconomic deprivation, hospital level, and other comorbidities. Surgery performed in the third trimester was associated with a significantly increased rate of prematurity (aOR: 1.38; 95% CI: 1.03-1.85), but lower rates of stillbirth (aOR: 0.1; 95% CI: 0.01-0.75) and Apgar score < 7 at the 5th minute (aOR: 0.2; 95% CI: 0.05-0.82), than surgery performed in the first trimester. CONCLUSIONS Pregnancies with nonobstetric surgery during gestation were associated with increased risks of prematurity, low birth weight, low Apgar scores, neonatal and infant death, longer admission, and higher medical expenses than those without surgery. Furthermore, surgery in the third trimester was associated with a higher rate of prematurity than surgery performed in the first trimester. TRIAL REGISTRATION Not applicable.

Abstract
BACKGROUND Primary hyperparathyroidism (PHPT) is the most common cause of pregnancy-related hypercalcemia. PHPT can cause maternal and fetal complications in pregnant women. General anesthesia for non-obstetric surgery in pregnant women is associated with maternal hazards and concerns regarding long-term neonatal neurocognitive effects. Surgical removal of the lesion in mid-pregnancy is currently the primary treatment option for pregnant patients with PHPT. However, the blood calcium concentration at which surgery should be considered remains under discussion due to the risk of miscarriage.
CASE SUMMARY A 31-year-old nulliparous woman at 11 wk of gestation was admitted to our hospital for parathyroidectomy. The patient had a history of intrauterine fetal death with unknown etiology at 16 wk of gestation 1 year prior. Her blood test results showed that the serum calcium level was elevated to 12.9 mg/dL, and the parathyroid hormone level was elevated to 157 pg/mL. In a neck ultrasound, it revealed a 0.8 cm × 1.5 cm sized oval, hypoechoic mass in the upper posterior of the left thyroid gland, which was compatible with parathyroid adenoma. Superficial cervical plexus block (SCPB) for parathyroidectomy was performed. After surgery, the obstetrician checked the status of the fetus, and there were no abnormal signs. Since then her calcium level returned to normal values after one week of surgery and a healthy male neonate of 2910 g was delivered vaginally at 38 wk of gestation.
CONCLUSION Our case suggests that SCPB can be an anesthetic option for parathyroidectomy during the first trimester of pregnancy.

Abstract
BACKGROUND Cardiovascular diseases are the leading cause of morbidity and mortality in pregnant women. On the other hand, cardiac surgery is not so common for pregnant women. CASE REPORT We present the case of a pregnant woman with diagnosed thrombosis of the mechanical aortic valve in the 12th gestational week. The patient underwent surgery, and successfully completed her pregnancy till the 37th gestational week. CONCLUSION We showed that, despite general anaesthesia during the first trimester of pregnancy, the application of the nonpulsatile flow of extracorporeal circulation and mild hypothermia, the operation was successfully completed and that both mother and fetus survived.

Abstract
Management of renal mass during pregnancy is challenging. There is no consensus regarding the fundamental timing issues (which trimester) of the interventions and patient positioning during the procedures. We present three pregnant women with renal mass and their management, focusing on patient positioning and timing of surgical intervention. All patients were positioned supine with a 30-degree rotation to the left lateral without signs of compromising fetal circulation. This report's three major takeaway points are the following: (1) Renal mass biopsy might be more beneficial in pregnant women than the normal population (unless CT findings suggest vascular angiomyolipomas) to achieve a definite diagnosis and avoid unnecessary interventions during pregnancy. (2) Surgical interventions, if indicated, should be performed as soon as possible and are applicable in all trimesters of pregnancy. (3) A minimum of 15-degree left lateral tilt (for both right- and left-sided renal masses) can provide enough venous return during the nephrectomy.

Abstract
BACKGROUND Chloroprocaine is a short-acting local anesthetic that has been used for spinal anesthesia in outpatient surgery. There is limited experience with spinal chloroprocaine for prophylactic cervical cerclage placement. We sought to determine the effective dose of intrathecal chloroprocaine for 90% of patients (ED90) undergoing prophylactic cervical cerclage placement. We hypothesized that the ED90 of intrathecal chloroprocaine when combined with 10-ug fentanyl would be between 33 and 54 mg. METHODS In this prospective 2-center double-blinded study, we enrolled women undergoing prophylactic cervical cerclage placement under combined spinal-epidural anesthesia. A predetermined dose of intrathecal 3% chloroprocaine with fentanyl 10 ug was administered. The initial dose was 45-mg intrathecal chloroprocaine. Subsequent dose adjustments were determined based on the response of the previous subject using an up-down sequential allocation with a biased-coin design. A dose was considered effective if at least a T12 block was achieved, and there was no requirement for epidural activation or intraoperative analgesic supplementation during the procedure. The primary outcome was the ED90 of intrathecal chloroprocaine with fentanyl 10 ug. Secondary outcomes included duration of surgery, anesthetic side effects, time to resolution of motor and sensory block, time to achieve recovery room discharge criteria, and patient satisfaction with anesthetic care. Isotonic regression was used to estimate the ED90. RESULTS Forty-seven patients were enrolled into the study. Two patients were excluded (1 protocol violation and 1 failed block). In total, 45 patients completed the study. The estimated ED90 (95% confidence interval) for intrathecal chloroprocaine combined with fentanyl 10 ug was 49.5 mg (45.0-50.1 mg). The median (interquartile range [IQR]) duration of surgery was 15 (10-24) minutes. Resolution of the motor (Bromage 0) and sensory block took a median time of 60 (45-90) minutes and 90 (75-105) minutes, respectively. The median time to achieve recovery room discharge criteria was 150 (139-186) minutes. Satisfaction with anesthetic management was high in all patients. There were no reports of postdural puncture headache or transient neurological symptoms postoperatively. CONCLUSIONS The ED90 of intrathecal chloroprocaine combined with fentanyl 10 ug was 49.5 mg. Intrathecal chloroprocaine was associated with rapid block recovery and high patient satisfaction, which makes it well suited for outpatient obstetric procedures.

Abstract
Introduction: The management of nephrolithiasis during pregnancy can be stressful for urologists due to concerns for investigations and treatments that may pose risk of fetal harm, and unfamiliarity with optimal management of these complex patients. In response, we created multi-disciplinary evidence-based guidelines to standardize the care for obstetric patients presenting with flank pain and suspicion for nephrolithiasis. Methods: A multi-disciplinary team involving Urology, Obstetric Anesthesiology, Obstetrics and Gynecology, Diagnostic Radiology, and Interventional Radiology from a single academic medical center was assembled. A PubMed search was performed using keywords of pregnancy/antepartum, nephrolithiasis/calculi/kidney stones, ureteroscopy, non-obstetric surgery, complications, preterm delivery, MRI, computerized tomography, renal bladder ultrasound (RBUS), and anesthesia to identify relevant articles. Team members reviewed their respective areas to create a comprehensive set of guidelines. One invited external expert reviewed the guidelines for validation purposes. Results: A total of 54 articles were reviewed for evidence synthesis. Four guideline statements were constructed to guide diagnosis and imaging, and seven statements to guide intervention. Guidelines were then used to create a diagnostic and intervention flowchart for ease of use. In summary, RBUS should be the initial diagnostic study. If diagnostic uncertainty still exists, a non-contrast CT scan should be obtained. For obstetric patients presenting with a septic obstructing stone, urgent decompression should be achieved. We recommend ureteral stent placement as the preferred intervention if local factors allow. Conclusions: We present a standardized care pathway for the management of nephrolithiasis during pregnancy. Our aim is to standardize and simplify the clinical management of these complex scenarios for urologists.

Abstract
Objective To estimate the safety and feasibility of laparoendoscopic single-site surgery (LESS) in pregnant patients with acute abdomen. Methods Baseline characteristics, surgical results, and obstetric and neonatal outcomes were retrospectively compared between single and multiport procedures in patients who underwent laparoscopic surgery during pregnancy between 2017 and 2021. Results Fifty-four pregnant patients were included: 26 who underwent LESS (salpingectomy, 11 cases/cystectomy, 15 cases) and 28 who underwent conventional laparoscopic surgeries (salpingectomy, 12 cases/cystectomy, 16 cases) during pregnancy. One patient in the single-port group required additional ports. No patients converted to laparotomy. In patients undergoing salpingectomy, the single-port group showed lower 8- and 24-h postoperative pain scores, shorter hospital stays, and lower Self-rating Anxiety Scale scores prior to discharge versus conventional laparoscopy. One patient experienced postoperative vaginal bleeding and a missed abortion during follow-up. In patients receiving cystectomy, 8- and 24-h pain scores, postoperative hospital stay, and anxiety scores were lower in the single-port versus multiport group. Other outcomes were comparable between the groups. Conclusion The feasibility and efficacy of laparoscopic surgery during pregnancy is similar between single- or multiport routes, however, the single-port route may be associated with less postoperative pain, shorter hospital stay, and lower anxiety.

Abstract
Diabetes mellitus (DM) is a noncommunicable disease reaching epidemic proportions around the world. It affects younger individuals, including women of childbearing age. Diabetes can cause diabetic retinopathy (DR), which is potentially sight threatening when severe nonproliferative DR (NPDR), proliferative DR (PDR), or sight-threatening diabetic macular oedema (STDME) develops. Pregnancy is an independent risk factor for the progression of DR. Baseline DR at the onset of pregnancy is an important indicator of progression, with up to 10% of women with baseline NPDR progressing to PDR. Progression to sight-threatening DR (STDR) during pregnancy causes distress to the patient and often necessitates ocular treatment, which may have a systemic effect. Management includes prepregnancy counselling and, when possible, conventional treatment prior to pregnancy. During pregnancy, closer follow-up is required for those with a long duration of DM, poor baseline control of blood sugar and blood pressure, and worse DR, as these are risk factors for progression to STDR. Conventional treatment with anti-vascular endothelial growth factor agents for STDME can potentially lead to foetal loss. Treatment with laser photocoagulation may be preferred, and surgery under general anaesthesia should be avoided. This review provides a management plan for STDR from the perspective of practising ophthalmologists. A review of strategies for maintaining the eyesight of diabetic women with STDR with emphasis on prepregnancy counselling and planning, monitoring and safe treatment during pregnancy, and management of complications is presented.

Abstract
Pregnancy is associated with a number of pathophysiological changes (including modification of vascular resistance, increased vascular permeability, and coagulative disorders) that can lead to specific (eclampsia, preeclampsia) or not specific (intracranial hemorrhage) neurological complications. In addition to these disorders, pregnancy can affect numerous preexisting neurologic conditions, including epilepsy, brain tumors, and intracerebral bleeding from cerebral aneurysm or arteriovenous malformations. Intracranial complications related to pregnancy can expose patients to a high risk of intracranial hypertension (IHT). Unfortunately, at present, the therapeutic measures that are generally adopted for the control of elevated intracranial pressure (ICP) in the general population have not been examined in pregnant patients, and their efficacy and safety for the mother and the fetus is still unknown. In addition, no specific guidelines for the application of the staircase approach, including escalating treatments with increasing intensity of level, for the management of IHT exist for this population. Although some of basic measures can be considered safe even in pregnant patients (management of stable hemodynamic and respiratory function, optimization of systemic physiology), some other interventions, such as hyperventilation, osmotic therapy, hypothermia, barbiturates, and decompressive craniectomy, can lead to specific concerns for the safety of both mother and fetus. The aim of this review is to summarize the neurological pathophysiological changes occurring during pregnancy and explore the effects of the possible therapeutic interventions applied to the general population for the management of IHT during pregnancy, taking into consideration ethical and clinical concerns as well as the decision for the timing of treatment and delivery.

Abstract
Heterotopic pregnancy (HP) is an uncommon clinical condition characterized by the coexistence of intrauterine and extra-uterine pregnancies. HP is a diagnostic challenge as the typical methods for the early diagnosis of ectopic pregnancy are confounded by the simultaneous presence of intrauterine pregnancy (IUP). Ruptured HP is a potentially life-threatening obstetric emergency and can result in significant morbidity and mortality. Early diagnosis is the key to a favorable outcome. With the increasing number of patients undergoing artificial reproductive technology (ART), which is an important risk factor for HP, the odds of encountering HP patients are also growing. Anesthesiologists are challenged by the need to manage a bleeding obstetric patient while simultaneously ensuring the safety of the IUP. We present perioperative management of a patient with bleeding ruptured HP for emergency laparotomy who went on to have a successful twin delivery 37w3d via cesarean section.

Abstract
Necessary nonobstetric surgical procedures should not be withheld from pregnant women for fear of risks to the women and their pregnancies; however, careful preoperative planning should be undertaken to mitigate risks that may be present. Fetal monitoring recommendations will be dependent on the woman's preferences, gestational age of the pregnancy, and situational-specific risks (including anticipated risk of cardiovascular instability). Some fetal heart rate changes (lower baseline, less variability) can be anticipated, depending on anesthetic agents utilized during the procedure, and should not routinely prompt delivery.

Abstract
Introduction Sonography and magnetic resonance imaging (MRI) may be helpful to obtain an accurate
diagnosis of acute abdominal pain in pregnancy. Adnexal torsion presenting in the first
or second trimester can be confirmed and treated through laparoscopic surgery; however
laparoscopic surgery in the third trimester can be difficult owing to the large uterus,
and a gridiron incision can be useful. Case Report/Case presentation An 18-year-old gravida 1, para 0 (G1P0) woman at 30 + 4 weeks of gestation presented
with sudden-onset cyclic pain in the right lower quadrant. Abdominal ultrasonography
showed a normal appendix, and MRI showed a normal appendix and normal ovaries. The
patient’s prominent tender point was marked and compared with the MR images, which
confirmed the mark as the position of the right ovary. Laparotomy was performed through
a gridiron incision, and a folded right ovary was identified. The ovary was unfolded,
and TachoSil® and Surgicel® were used to maintain the unfolded position. The patient’s
pain resolved, and her postoperative course was uneventful. She delivered a healthy,
2540-g male baby at 35 weeks’ gestation. Discussion/Conclusions A gridiron incision was useful to treat a folded ovary in the third trimester and to
evaluate the adnexa and minimize uterine manipulation.

Abstract
The aim of fetal cardiac interventions (FCI), as other prenatal therapeutic procedures, is to bring benefit to the fetus. However, the safety of the mother is of utmost importance. The objective of our study was to evaluate the impact of FCI on maternal condition, course of pregnancy, and delivery. 113 mothers underwent intrauterine treatment of their fetuses with critical heart defects. 128 percutaneous ultrasound-guided FCI were performed and analyzed. The patients were divided into four groups according to the type of FCI: balloon aortic valvuloplasty (fBAV), balloon pulmonary valvuloplasty (fBPV), interatrial stent placement (IAS), and balloon atrioseptoplasty (BAS). Various factors: maternal parameters, perioperative data, and pregnancy complications, were analyzed. There was only one major complication—procedure-related placental abruption (without need for blood products transfusion). There were no cases of: procedure-related preterm prelabor rupture of membranes (pPROM), chorioamnionitis, wound infection, and anesthesia associated complications. Tocolysis was only necessary only in two cases, and it was effective in both. None of the patients required intensive care unit admission. The procedure was effective in treating polyhydramnios associated with fetal heart failure in six out of nine cases. Deliveries occurred at term in 89%, 54% were vaginal. The results showed that FCI had a negligible impact on a further course of pregnancy and delivery.

Abstract
This study aimed evaluate the feasibility of modified laparoscopic transabdominal cervicoisthmic cerclage (LTCC) and its impact on recurrent pregnancy loss (RPL) and is a retrospective observational cohort study of patients who underwent modified LTCC from 2003 to 2018 (n = 299). The surgery was performed at a mean gestational age of 12.5 weeks (range 10.5-17.5 weeks). Of the 299 patients, 190 were reported as having undergone abortion (one abortion: 91 (47.9%), two: 59 (31.1%), three or more: 40 (21.1%)) before the present pregnancy and prior to the surgery. The mean operation time was 47.4 min (range 15-100 min). We followed up with 205 of 299 patients and recorded their obstetric outcomes. There were 176 successful deliveries via cesarean section, and the fetal survival rate was 85.9% (176/205). The results of this study suggest that modified LTCC is a safe and feasible surgical option during pregnancy for patients with a history of RPL due to cervical factors.

Abstract
BACKGROUND Existing data on safety of non-obstetric surgery during pregnancy appear limited and conflicting. This study aimed to assess perinatal outcomes and complications in pregnant women undergoing non-obstetric surgeries. METHODS A single-site Australian study was performed utilizing a 10-year data (2009-2018) collected retrospectively. Descriptive statistics were used to summarize the characteristics of the study population. Statistical analyses between groups were conducted by independent t-test or Mann-Whitney (for means between groups) and by chi-squared/Fisher's exact test (for categorical variables). RESULTS A total of 108 pregnant women underwent non-obstetric surgery, with an increasing trend in annual numbers since 2014. The majority of women (91%) underwent surgeries as an emergency procedure, and under general anaesthesia (69.8%). Procedures during the first trimester comprised 45%, making it the most common trimester for non-obstetric surgeries. The most common cause for surgery arose in the gastrointestinal/digestive tract (39%). Overall perinatal complication rate was 19% with the rate of miscarriage/foetal loss, preterm birth and intrauterine growth restriction/small for gestational age being 4.7%, 10.4% and 3.8%, respectively. A total of 46 patients underwent intra-abdominal surgery. The most common surgery in the laparoscopy group was appendicectomy (56%), whereas adnexal pathology (54%) contributed to the majority of laparotomies. Subgroup comparison showed no significant difference in perinatal outcomes except for caesarean delivery rate (24% versus 67% for laparoscopy versus open, respectively (P = 0.04)). CONCLUSION With an overall perinatal complication rate of 19%, the rate of adverse perinatal outcomes following non-obstetric surgery during pregnancy in our study was low and comparable to those of the general population.

Ketamine inhibits neuronal differentiation by regulating brain-derived neurotrophic factor (BDNF) signaling. Toxicol In Vitro 2021; 72:105091.

Abstract
Ketamine is widely used in pediatric anesthesia, perioperative sedation, and analgesia. Knowledge of anesthesia neurotoxicity in humans is currently limited by the difficulty of obtaining neurons and performing developmental toxicity studies in fetal and pediatric populations. However, mouse embryonic stem cells (mESCs) derived from embryos at the preimplantation stage demonstrate an unlimited ability to self-renew and generate different cell types and are a valuable tool for clinical research. Thus, in this study, a model was employed to investigate the mechanism by which ketamine (200 nM) influences the neuronal differentiation of mESCs. Mouse ESCs were treated with an anesthetic dose of ketamine, and neuronal differentiation was significantly inhibited on day 5. Downregulation of brain-derived neurotrophic factor (BDNF) by shRNA was found to have the same inhibitory effect. Furthermore, a rescue experiment indicated that BDNF overexpression markedly restored the neuronal differentiation inhibited by ketamine in the ketamine/BDNF group on day 5. Taken together, these data suggested that ketamine inhibited the neuronal differentiation of mESCs, possibly by interfering with BDNF. The results of the current study may provide novel ideas for preventing ketamine toxicity in the developing fetus.

Abstract
Patients who present with brain tumors during pregnancy require unique imaging and neurosurgical, obstetrical, and anesthetic considerations. Here, we review the literature and discuss the management of patients who present with brain tumors during pregnancy. Between 2009 and 2019, 9 patients were diagnosed at our institution with brain tumors during pregnancy. Clinical information was extracted from the electronic medical records. The median age at presentation was 29 years (range, 25-38 years). The most common symptoms at presentation included headache (n=5), visual changes (n=4), hemiparesis (n=3), and seizures (n=3). The median gestational age at presentation was 20.5 weeks (range, 11-37 weeks). Of note, 8 patients (89%) delivered healthy newborns, and 1 patient terminated her pregnancy. In addition, 5 patients (56%) required neurosurgical procedures during pregnancy (gestational ages, 14-37 weeks) because of disease progression (n=2) or neurologic instability (n=3). There was 1 episode of postneurosurgery morbidity (pulmonary embolism [PE]) and no surgical maternal mortality. The median length of follow-up was 15 months (range, 6-45 months). In cases demonstrating unstable or progressive neurosurgical status past the point of fetal viability, neurosurgical intervention should be considered. The physiological and pharmacodynamic changes of pregnancy substantially affect anesthetic management. Pregnancy termination should be discussed and offered to the patient when aggressive disease necessitates immediate treatment and the fetal gestational age remains previable, although neurologically stable patients may be able to continue the pregnancy to term. Ultimately, pregnant patients with brain tumors require an individualized approach to their care under the guidance of a multidisciplinary team.

Abstract
OBJECTIVE Patients with pregnancy-associated secondary brain tumors (PASBT) are challenging to manage. Because no guidelines for the management of such patients currently exist, we performed a systematic review of the literature using PRISMA guidelines with a discussion of management from a neurosurgeon's perspective. METHOD Systematic review of the literature using PRISMA guidelines from 1999 to 2018. RESULTS We identified 301 studies of which 16 publications (22 patients reporting 25 pregnancies, 20 deliveries, 5 early terminations) were suitable for final analysis. The most frequent primary cancers were breast (8/22, 36.36%), skin (6/22, 27.27%), and lung (5/22, 22.73%). Four patients (18.18%) had neurosurgical procedures during their pregnancies. Five patients (22.73%) received neurosurgical resection after their pregnancies. Nine patients (40.91%) received radiation therapy and seven patients (31.82%) received chemotherapy during pregnancy while seven patients (31.82%) received chemotherapy and radiation after pregnancy. There was 1 fetal death (5%) out of 20 healthy deliveries. Five pregnancies (20%) were terminated in the first trimester due to a need for urgent neurosurgical intervention. CONCLUSION Management of PASBT remains a challenging issue. Maternal and fetal risks associated with surgical resection and teratogenicity due to adjuvant therapy should be discussed in the context of a multidisciplinary team. Timing of surgery and the use of systemic chemoradiation depends on the gestational age (GA) of the fetus, extent, and control of the mother's primary and metastatic disease. Guidelines need to be established to help neuro-oncology teams safely and effectively manage this group of patients.

Abstract
PURPOSE To evaluate the safety and efficacy of percutaneous nephrostomy (PCN) in pregnancy. MATERIALS AND METHODS PCN tubes were placed during 52 pregnancies in 49 patients from 2008 to 2018. The medical records during pregnancies were retrospectively reviewed for imaging findings, procedural parameters, outcomes of delivery, and complications. RESULTS The mean gestational age on percutaneous nephrostomy placement was 27 weeks (range, 8-36 weeks). PCN catheters were placed for the following indications: 1) flank or lower abdominal pain (42%), 2) obstructing calculi (37%), 3) pyelonephritis (20%), and 4) obstructing endometrioma (2%). Prior to PCN, retrograde ureteric stenting was performed in 17 of 49 patients (34%) and attempted but failed in 4 patients (8%). Nephrostomy drainage relieved pain completely or significantly in all 12 patients without prior ureteral stenting, but in only 4 of 10 with retrograde ureteric stents. In one patient in whom the ureteral stent had been removed, PCN relieved her flank pain. The mean number of PCN catheter exchanges was 1.6, ranging from 0 to 9, with a mean time interval of 21.3 days between exchanges. There were 29 difficult exchanges due to encrustation in 15 patients with a mean of 20.5 days between exchanges. CONCLUSIONS PCN drainage is a safe and effective treatment for managing symptomatic hydronephrosis in pregnant patients but is less effective in treating pain when retrograde ureteral stents are in place. Rapid encrustation, seen more commonly in pregnancy, tends to recur in the same patients and requires more frequent exchanges than the general population.

Propofol inhibits the expression of Abelson nonreceptor tyrosine kinase without affecting learning or memory function in neonatal rats. Brain Behav 2020; 10:e01810. [PMID: 32869521 PMCID: PMC7667295 DOI: 10.1002/brb3.1810] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2020] [Revised: 07/17/2020] [Accepted: 08/04/2020] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVE Propofol is one of the most commonly used intravenous drugs to induce and maintain general anesthesia. In vivo and in vitro studies have shown that propofol can affect neuronal growth, leading to apoptosis and impairing cognitive function. The Abelson nonreceptor tyrosine kinase (c-Abl) is associated with both neuritic plaques and neurofibrillary tangles in the brains of patients with Alzheimer's disease and other neurodegenerative diseases. This study aimed to explore the effect of propofol on apoptosis and neurocognition through its regulation of c-Abl expression in vivo and in vitro. MATERIALS AND METHODS In this study, primary hippocampal neurons were cultured and exposed to propofol at different concentrations. Protein expression was measured by Western blotting and coimmunoprecipitation. The c-Abl transcription level was verified by fluorescence quantitative PCR. Reactive oxygen species (ROS) levels were detected by flow cytometry. In addition, an animal experiment was conducted to assess neuronal apoptosis by immunofluorescence staining for caspase-3 and to evaluate behavioral changes by the Morris water maze (MWM) test. RESULTS The in vitro experiment showed that propofol significantly decreased c-Abl expression and ROS levels. In addition, propofol has no cytotoxic effect and does not affect cell activity. Moreover, in the animal experiment, intraperitoneal injection of 50 mg/kg propofol for 5 days obviously decreased the expression of c-Abl in the neonatal rat brain (p < .05) but did not significantly increase the number of caspase-3-positive cells. Propofol treatment did not significantly reduce the number of platform crossings (p > .05) or prolong the escape latency of neonatal rats (p > .05) in the MWM test. CONCLUSIONS The present data suggest that reduced expression of this nonreceptor tyrosine kinase through consecutive daily administration of propofol did not impair learning or memory function in neonatal rats.

Combined Acetabulum Fracture and Hip Dislocation in an 18-Year-Old Female at 35-Week Gestation: A Case Report and Review of the Literature. Case Rep Orthop 2020; 2020:8888015. [PMID: 32774967 PMCID: PMC7396045 DOI: 10.1155/2020/8888015] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2020] [Revised: 07/08/2020] [Accepted: 07/16/2020] [Indexed: 12/02/2022] Open
Abstract
Caring for an injured, pregnant patient can be a management challenge. We report the case of an 18-year-old female who sustained a left acetabulum fracture with a concurrent hip dislocation at 35 weeks' gestation following a motor vehicle accident. Through an interdisciplinary, team-based approach, the patient was guided through obstetric delivery and orthopedic surgical fracture fixation without complication. By being familiar with the unique challenges in management posed by pregnant patients, orthopedic surgeons can be better equipped to minimize morbidity and mortality in this patient population while maximizing clinical outcomes.

Abstract
Introduction In utero, exposure to sevoflurane (a commonly used inhalation anesthetic) can lead to hearing impairment in offspring mice, but the underlying impairment mechanism is not known. Materials and Methods Day-15 pregnant mice were treated with 2.5% sevoflurane for 2 h to investigate sevoflurane ototoxicity. Cochleae from offspring mice were harvested for hair-cell and ribbon-synapse assessments. Hearing in offspring mice was assessed at postnatal day 30 using an auditory brainstem-response (ABR) test. Cochlear-explant cultures from offspring mice were exposed to 2.5% sevoflurane for 6 h. Immediately after treatment, explants were assessed for hair-cell morphology, mitochondrial oxidative stress, and autophagy. Results In utero, sevoflurane exposure impaired hearing in the offspring is demonstrated by a decrease in ABR wave I amplitudes, a marker for ribbon-synapse functionality. Sevoflurane exposure caused no obvious damage to hair cells, but cochlear ribbon synapses were reduced in postnatal day 15 offspring, and partially recovered by postnatal day 30. Sevoflurane treatment also increased mitochondrial reactive-oxygen species stress and decreased autophagy in the cochlear explants. Conclusion These results suggest that oxidative stress and reduced autophagy may underly ribbon-synapse involvement in sevoflurane-induced hearing loss.
