Poggetti F, Schwarz G, Piano M, Gatti A, Aquilano MC, Di Como M, Protti A, Bonoldi E, Agostoni EC, Cascio Rizzo A. Intraluminal carotid thrombus leading to postpartum stroke: a case study. Neurol Sci 2024; 45:1735-1739.

Abstract
BACKGROUND Intraluminal non-occlusive thrombus (ILT) is a rare cause of ischemic stroke. Although in most cases ILT is associated with arterial wall disorders, it has also been documented in patients with thrombophilic conditions. CASE REPORT We present a case of carotid ILT in a 38-year-old puerperal woman with pregnancy-induced hypercoagulability. Following in vitro fertilization pregnancy, she experienced acute left-sided weakness 9 days after delivery. CT angiography revealed an intraluminal filling defect in the right carotid bulb, suggestive of a thrombus, along with ipsilateral MCA sub-occlusion. Mechanical thrombectomy was performed, achieving complete vessel recanalization without any endovascular intervention on the carotid ILT. Comprehensive evaluation excluded any underlying carotid vessel wall disease (such as atherosclerosis, inflammatory diseases, arterial dissection, focal dysplasia), inherited or acquired thrombophilia, and the sole prothrombotic risk factor identified was the puerperium. Histological thrombus analysis showed fibrin/platelet-rich material with significant macrophage infiltration (consistent with an intermediate/organized thrombus, suggesting potential embolization from a pre-existing carotid ILT). Anti-thrombotic treatment (acetylsalicylic acid 100 mg and enoxaparin 6000 UI) resulted in complete thrombus resolution at follow-up. CONCLUSION ILT should be considered a potential case of embolic stroke in pregnancy or puerperium. Vessel imaging is essential for diagnosis. Histological thrombus analysis can provide insights into the pathophysiological mechanisms of stroke.

Abstract
Occupational therapy practitioners' (OTP's) perceptions of their role in working on the acute postpartum hospital unit are unknown. The objective of this research was to determine the perspectives of OTP's enrolled in a continuing education course to gain competency in providing services to acute postpartum patients. Investigators engaged in a phenomenology consisting of semi-structured interviews with six OTP's working in acute care hospitals preparing to work on the postpartum unit. Three themes emerged from transcripts: (a) Its' Not THAT Different; (b) Willing To Try; and (c) Shifting Focus To Mom. OTPs working in hospitals identified existing skills applicable to working with acute postpartum patients, a need for additional learning to enhance competence, and a desire to focus support for the birthing person to improve maternal outcomes. Hospital onboarding and/or entry-level OTP programs should consider including education on the postpartum population. Future research should focus on program implementation on acute postpartum hospital units.

Abstract
Stroke is a leading cause of death and disability in the United States and worldwide, necessitating comprehensive efforts to optimize stroke risk factor management. Health disparities in stroke incidence, prevalence, and risk factor management persist among various race/ethnic, geographic, and socioeconomic populations and negatively impact stroke outcomes. This review highlights existing literature and guidelines for stroke risk factor management, emphasizing health disparities among certain populations. Moreover, stroke risk factors for special groups, including the young, the very elderly, and pregnant/peripartum women are outlined. Strategies for stroke risk factor improvement at every level of the health care system are discussed, from the individual patient to providers, health care systems, and policymakers. Improving stroke risk factor management in the context of the social determinants of health, and with the goal of eliminating inequities and disparities in stroke prevention strategies, are critical steps to reducing the burden of stroke and equitably improving public health.

Toyama G, Tsuboguchi S, Igarashi K, Saji E, Konno T, Onodera O. A case report of reversible cerebral vasoconstriction syndrome with thunderclap headache significantly exacerbated in the supine position and alleviated in the standing position. BMC Neurol 2023; 23:348. [PMID: 37789263 PMCID: PMC10546625 DOI: 10.1186/s12883-023-03381-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2023] [Accepted: 09/11/2023] [Indexed: 10/05/2023] Open
Abstract
BACKGROUND Reversible cerebral vasoconstriction syndrome (RCVS) is characterized by sudden onset thunderclap headache and multiple segmental reversible cerebral vasoconstrictions that improve within 3 months. The postpartum period is a well-known precipitating factor for the onset of RCVS. Cerebral venous thrombosis (CVT) causes thunderclap headaches in the postpartum period. While headache in CVT is sometimes exacerbated in the supine position, the severity of the headache in RCVS is usually independent of body position. In this study, we report a case of RCVS with thunderclap headache exacerbated in the supine position, and headache attacks that resolved quickly in the standing position during the postpartum period. CASE PRESENTATION A 33-year-old woman presented with a sudden increase in blood pressure and thunderclap headache on the fifth postpartum day (day 1: the first sick day). The headache was severe and pulsatile, with onset in the supine position in bed, and peaked at approximately 10 s. It was accompanied by nausea and chills but there were no scintillating scotomas or ophthalmic symptoms. The headache resolved in the standing or sitting position but was exacerbated and became unbearable within a few seconds when the patient was in the supine position. Therefore, she was unable to lie supine at night. Computed tomography angiography (CTA) of the head on day 2 and magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) on day 3 showed no abnormalities. However, considering the possibility of RCVS, verapamil was initiated on day 3. The headache resolved the following day. MRA of the head on day 10 revealed diffuse and segmental stenoses in the bilateral middle and posterior cerebral arteries and basilar artery. Therefore, the patient was diagnosed with RCVS. The headache gradually resolved and disappeared completely on day 42. Cerebral vasoconstriction was also improved on MRA on day 43. CONCLUSIONS This postpartum RCVS case was notable for the exacerbation of headaches in the supine position. For the diagnosis of thunderclap headache in the postpartum period, RCVS should be considered in addition to CVT when the patient presents with a headache that is exacerbated in the supine position.

Abstract
OBJECTIVE To examine the outcomes of the subsequent pregnancies from women with a previous pregnancy-associated stroke (PAS) in comparison to matched controls. DESIGN Population-based retrospective cohort study. SETTING AND POPULATION All women with a PAS in Finland 1987-2016 (n = 235) and controls (n = 694). METHODS We identified all subsequent deliveries and induced and spontaneous abortions for women with a previous PAS and their matched controls from the Medical Birth Register and the Hospital Discharge Register until 2016. The number, course and outcomes of the subsequent pregnancies were compared. Patient records were studied for PAS recurrence. MAIN OUTCOME MEASURES PAS recurrence and pregnancy complications. RESULTS Women with a previous PAS had fewer subsequent deliveries: 73 (31.1%) women had 122 deliveries in all, whereas 303 (47.3%) of the controls had 442 deliveries (age-adjusted odds ratio [OR] 0.54, 95% CI 0.38-0.76). Hypertensive disorders of pregnancy (HDP) (17.2% versus 5.7%, age-adjusted OR 4.0, 95% CI 1.7-9.3), especially chronic hypertension (age-adjusted OR 5.9, 95% CI 1.5-24.7), and any diabetes during pregnancy (24.6% versus 14.5%, age-adjusted OR 2.0, 95% CI 1.1-3.8) were more common in cases. Regarding HDP, the difference between groups was explained by underlying factors such as index pregnancy HDP (multivariable OR 2.4, 95% CI 0.8-6.7). PAS recurred in four cases (5.5%). CONCLUSIONS Subsequent pregnancies of women with a history of PAS are more often complicated with hypertensive disorders of pregnancy and any diabetes during pregnancy. PAS recurrence risk is considerable.

Neurological Complications in Pregnancy and the Puerperium: Methodology for a Clinical Diagnosis. J Clin Med 2023; 12:jcm12082994. [PMID: 37109329 PMCID: PMC10141482 DOI: 10.3390/jcm12082994] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2023] [Revised: 04/06/2023] [Accepted: 04/18/2023] [Indexed: 04/29/2023] Open
Abstract
Neurological complications in pregnancy and the puerperium deserve particular attention from specialists due to the worsening of the clinical picture for both the mother and the fetus. This narrative review of existing data in the literature aims to analyze the most common "red flag symptoms" attributable to neurological complications such as pre-eclampsia (PE), eclampsia, HELLP syndrome, posterior reversible encephalopathy syndrome (PRES), cerebral vasoconstriction syndrome (RCVS), stroke, CVS thrombosis, pituitary apoplexy, amniotic fluid embolism and cerebral aneurysm rupture, with the aim of providing a rapid diagnostic algorithm useful for the early diagnosis and treatment of these complications. The data were derived through the use of PubMed. The results and conclusions of our review are that neurological complications of a vascular nature in pregnancy and the puerperium are conditions that are often difficult to diagnose and manage clinically. For the obstetrics specialist who is faced with these situations, it is always important to have a guide in mind in order to be able to unravel the difficulties of clinical reasoning and promptly arrive at a diagnostic hypothesis.

Abstract
BACKGROUND Pregnancy-related intracranial hemorrhage (ICH) is a rare but potentially life-threatening event with complex and varied cause, such as HELLP syndrome and hemophagocytic syndrome. CASE PRESENTATION A 33-year-old patient underwent a cesarean section with a preliminary diagnosis of "severe preeclampsia and class3 HELLP syndrome ". The patient had poor response to language before surgery, and the catheter drainage fluid was hematuria. Later, the surgeon reported severe bleeding in the operation. Following thromboelastography (TEG) result and postoperative laboratory tests confirmed class1 HELLP syndrome and ICH occurred on the second day after the surgery, and hemophagocytic syndrome was diagnosed during subsequent treatments. CONCLUSION For patients with HELLP syndrome, we should pay attention to their coagulation condition. The coagulation tests and platelet counts should be repeated if their clinical presentation changed. Those with neurological alarm signs should receive CT or MRI scan. If a pregnant woman had prolonged hemocytopenia and thrombocytopenia, not only the HELLP but also the hemophagocytic syndrome should be considered.

Abstract
Background Postpartum hemorrhage is the major cause of maternal deaths due to childbirth and also responsible for maternal morbidity. Objectives In this study we set out to look the incidence of postpartum hemorrhage in our population, to identify the most important risk factors for postpartum hemorrhage and thus develop a predictive risk calculator for postpartum hemorrhage and transfusion. Study design data was taken from patients who presented vaginal delivery or cesarean section from January 1 to December 31, 2016, the variables taken into account as risk factors were as follows: Gestational age, history of chronic or gestational hypertension, preeclampsia, previous abortions, parity, previous cesarean section, placenta previa, labor time, and postpartum hemorrhage as the event of interest. An objective quantification was performed on a weight scale in grams for the estimation of bleeding, considering postpartum hemorrhage those with >500 ml in vaginal delivery and >1000 ml of blood loss in cesarean section. Subsequently, a predictive risk calculator was developed using the Naïve Bayes algorithm. Results A success rate of 58% was obtained in the identification of patients at high risk of hemorrhage, and 36% for transfusion, with a sensitivity of 50.7% and specificity of 64.06%, identifying as risk factors for postpartum hemorrhage gestational age between 35 and 40 weeks, hypertension and preeclampsia, previous cesarean section, duration of labor <1 h or more than 10 h, placenta previa and previous history of postpartum hemorrhage. Conclusion A postpartum hemorrhage risk calculator has been designed, which due to its improved accuracy after incorporation of data becomes a useful tool that will require a larger study population to improve its performance in clinical practice and more similar studies to validate it.

Abstract
A 25-year-old woman was admitted to the obstetrics ward when presented with a sudden onset of expressive aphasia and minor right facial palsy 48 hours after forceps-assisted delivery. The intrahospital emergency team was immediately mobilized. The patient had a blood pressure (BP) of 119/79 mmHg, heart rate of 114 bpm, O2 saturation of 97%, and blood glucose level of 136 mg/dL. Trauma and toxic exposure were ruled out. A rapid EKG was performed with no significant changes. Assuming an acute stroke, the patient immediately underwent brain CT (approximately 15 minutes after the beginning of the symptoms), which revealed no signs of hemorrhage, an ischemic area, or masses. Brain CT angiography was then performed; however, no major brain artery obstruction was found. With brain hemorrhage ruled out and persistent neurologic deficits, the case was discussed between the emergency team doctor and the patient's obstetrician, and intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator (rt-PA) was started approximately 45 minutes after the onset of symptoms. After treatment completion, the patient had a complete resolution of the neurological deficits. The patient remained under strict observation at the acute stroke unit (ASU), and no secondary brain hemorrhage or post-partum-related complications were noted.

Abstract
The development of preeclampsia during pregnancy may have long-term effects on brain aging in women. Associations between preeclampsia and vascular dementia have been established, however the connection between preeclampsia and Alzheimer's disease has not been as thoroughly explored. Both preeclampsia and Alzheimer's disease have been associated with misfolded amyloid beta proteins and inflammation; due to these similarities, in this minireview, we examined the potential links between a history of preeclampsia and the development of dementia. We also discussed how hypertensive disorders of pregnancy may relate to both normal brain aging and dementia to highlight the need for additional research regarding the long-term cognitive effects of preeclampsia on the brain.

Abstract
Thromboembolism is the third leading vascular disease, with a high annual incidence of 1 to 2 cases per 1000 individuals within the general population. The broader term venous thromboembolism generally refers to deep vein thrombosis, pulmonary embolism, and/or a combination of both. Therefore, thromboembolism can affect both – the central and peripheral veins. Arterial thromboembolism causes systemic ischemia by disturbing blood flow and oxygen supply to organs, tissues, and cells causing, therefore, apoptosis and/or necrosis in the affected tissues. Currently applied antithrombotic drugs used, e.g. to protect affected individuals against ischemic stroke, demonstrate significant limitations. For example, platelet inhibitors possess only moderate efficacy. On the other hand, thrombolytics and anticoagulants significantly increase hemorrhage. Contextually, new approaches are extensively under consideration to develop next-generation antithrombotics with improved efficacy and more personalized and targeted application. To this end, phytochemicals show potent antithrombotic efficacy demonstrated in numerous in vitro, ex vivo, and in vivo models as well as in clinical evaluations conducted on healthy individuals and persons at high risk of thrombotic events, such as pregnant women (primary care), cancer, and COVID-19-affected patients (secondary and tertiary care). Here, we hypothesized that specific antithrombotic and antiplatelet effects of plant-derived compounds might be of great clinical utility in primary, secondary, and tertiary care. To increase the efficacy, precise patient stratification based on predictive diagnostics is essential for targeted protection and treatments tailored to the person in the framework of 3P medicine. Contextually, this paper aims at critical review toward the involvement of specific classes of phytochemicals in antiplatelet and anticoagulation adapted to clinical needs. The paper exemplifies selected plant-derived drugs, plant extracts, and whole plant foods/herbs demonstrating their specific antithrombotic, antiplatelet, and fibrinolytic activities relevant for primary, secondary, and tertiary care. One of the examples considered is antithrombotic and antiplatelet protection specifically relevant for COVID-19-affected patient groups.

Abstract
Headache is a common symptom in pregnancy. The differential diagnosis for headache in pregnancy is broad and includes conditions that range in acuity and severity. Most headaches in pregnancy are migraine or tension-type headaches. However, pregnant women are at an increased risk of vascular causes of headache due to hormone changes and increased hypercoagulability in pregnancy. A careful history, physical examination, and possible diagnostic workup should be performed. Treatment of headache in pregnancy varies according to the etiology, but care should be taken when performing diagnostic studies and considering pharmacologic treatments, given the possible risk to the mother and fetus.

Abstract
Background Although pregnancy‐induced hypertension (PIH) is associated with an elevated cardiovascular risk, long‐term studies or prepregnancy baseline data are scarce. Therefore, using a large nationwide cohort with prepregnancy periodic health screening data, we investigated whether clinically significant arrhythmia incidence increases after PIH. Methods and Results Data were extracted from the Korea National Health Insurance database and combined with the National Health Screening Examination database; women who gave birth between 2007 and 2015 and underwent the national health screening test within a year before pregnancy were followed up until 2016. We excluded women who had a diagnosis of arrhythmia within 1 year before pregnancy. The primary outcome was significant arrhythmia during the year after delivery. Secondary analysis included only specific diagnostic codes of arrhythmia with clinical significance. Additionally, the risk of arrhythmia was stratified by the use of magnesium sulfate. Of 2 035 684 women (PIH; n=37 297 versus normotensive pregnancy; n=1 998 387), the PIH group had a higher prepregnancy risk profile and showed a higher incidence of arrhythmia than women with normotensive pregnancies within 1 year. Women with PIH had a significantly higher risk of atrial flutter/fibrillation and atrioventricular block, but not lethal arrhythmias. Other predictors of arrhythmia development included advanced maternal age and cesarean section. Stratified analysis showed a higher risk of arrhythmia with magnesium sulfate use. Conclusions PIH was significantly associated with the development of arrhythmia within 1 year after delivery. Nevertheless, the incidence of lethal arrhythmias was not increased by PIH. Arrhythmia, especially atrial fibrillation, may largely contribute to increasing the future cardiovascular risk in women with a PIH history.

Abstract
BACKGROUND AND PURPOSE Hypertensive disorders of pregnancy (HDP) comprise 4 subtypes. Previous studies have not investigated the relationship between stroke risk, different HDP subtypes, and follow-up time, which was the purpose of this study. METHODS Data of 17 588 women aged 18 to 45 years who had a history of HDP in Taiwan from 2000 to 2017 was retrospectively reviewed. After matching with confounders, 13 617 HDP women and 54 468 non-HDP women were recruited. RESULTS HDP women had an adjusted hazard ratio (aHR) of 1.71 (95% CI, 1.46-2.00) for stroke, and 1.60 (1.35-1.89) and 2.98 (2.13-4.18) for ischemic and hemorrhagic stroke, respectively (P<0.001 for all). The overall stroke risk in the HDP group was still 2.04 times 10 to 15 years after childbirth (1.47-2.83, P<0.001). Although the risks of both ischemic and hemorrhagic stroke persisted, their risk time trends were different. The risk of ischemic stroke reached peak during 1 to 3 years after childbirth with an aHR of 2.14 (1.36-3.38), while hemorrhagic stroke risk gradually increased and had an aHR of 4.64 (2.47-8.73) after 10 to 15 years of childbirth (both P<0.001). Among the 4 HDP subtypes, chronic hypertension with superimposed preeclampsia had the highest stroke risk (aHR=3.86, 1.91-7.82, P<0.001), followed by preeclampsia-eclampsia (aHR=2.00, 1.63-2.45, P<0.001), and gestational hypertension (aHR=1.68, 1.13-2.52, P<0.05); chronic preexisting hypertension had the lowest stroke risk (aHR=1.27, 0.97-1.68, P>0.05). Furthermore, multiple HDP combined with preeclampsia had aHR of 5.48 (1.14-26.42, P<0.05). CONCLUSIONS The effect of HDP on the risk of future stroke persisted for up to 17 years, both for ischemic and hemorrhagic strokes. The presence of multiple HDP and preeclampsia further increase the stroke risk.

Abstract
OBJECTIVE To study the frequency of CeAD that developed during pregnancy or in post partum period among all CeADs in women; to study the course of pregnancy in women with prior CeAD. MATERIAL AND METHODS 162 women (mean age 37.1±4.1 years) with CeAD we examined at the Research Center of Neurology (Moscow), 98% women were studied during last 15 years. 140 women were of childbearing age (≤45 years, mean age - 35±2.8 years). All patients were interviewed whether or not CeAD occurred during pregnancy or in post partum period (CeADPPP). Obstetric history before and after CeAD was studied in 57 women of childbearing age (average age - 35.9±7.3 years at CeAD development). RESULTS CeADPPP developed in 6 out of 162 all female patients (3.7%) or of 140 childbearing age patients (4.3%). It occurred 2-6 months (4 patients) and 10 days after delivery (1 patient), or on the 25th week of pregnancy (1 patient). CeADPPP patients were younger than patients with CeAD out of pregnancy or postpartum period (29.8±8 years vs 35.1±6.7 years, p>0.05). CeADPPP in comparison with CeAD outside these periods more often involved internal carotid artery (ICA) (50% vs 35%, p=0.666), more often occurred in 2-3 arteries (50% vs 31%, p=0.386) and more often was accompanied by dissecting aneurysm development (50% vs 8%, p=0.013). After CeAD, 18 out of 57 patients in whom obstetric history was studied, including 3 patients with postpartum dissection had 29 pregnancies. The pregnancy outcomes were as follows: childbirth (17 pregnancies, 59%), fetal loss (8 pregnancies, 27%) and medical abortion (4 pregnancies, 14%). Delivery occurred on average 4.5±2.061 years after CeAD in women aged 33.0±4.25 years (cesarean section - 15 patients). Fetal loss occurred at 7.4±3.5 weeks of pregnancy in women aged 37.6±3.13 years on average 2.7±1.4 years after CeAD. Fetal loss frequency after CeAD was higher than before it (27% vs 7%, p=0.016). There were no CeAD recurrences during pregnancy and postpartum period in women who had previously undergone CeAD. CONCLUSION CeADPPP frequency among all dissections in women is 3.7-4.3%. The risk of CeAD recurrence during pregnancy or the postpartum period after prior CeAD is very low. The risk of fetal loss during 2.7±1.4 years after CeAD is higher than before it (27% vs 7%). Hormonal and growth factors associated with pregnancy and the postpartum period is suggested to contribute to cervical artery wall damage. It is possible that the prolonged action of some of these factors may disrupt the placental vessels formation, predisposing to miscarriage.

Abstract
Postpartum cerebral arterial dissections are rare, and the clinical features, diagnosis, and treatment approaches are not clear to many physicians. This study was to investigate the clinical features, diagnosis, and treatment of postpartum cerebral arterial dissections.One patient with postpartum cerebral arterial dissections enrolled in our hospital was analyzed. All patients with postpartum cerebral arterial dissections retrieved from the PubMed were also included in this study and analyzed.A total of 45 patients with postpartum cerebral arterial dissections were retrieved including our case, with an age range of 24 to 44 years (mean 34). Thirty-six (80%) patients were older than 30 years of age (mean 35). There were 17 cases of cesarean section, 14 cases of natural labor, and 14 cases whose delivery modes were not reported. The clinical symptoms included headache in 35 cases (78%) and neck pain in 14 (31%). The symptoms occurred at a mean time of 11 days (range 0-53 days) following delivery. Among 45 patients, arterial dissections involved unilateral carotid or vertebral artery in 29 cases (64%), bilateral carotid or vertebral arteries in 8 (18%), 3 arteries in 3 (7%), and all bilateral carotid and vertebral arteries in 5 (11%). Fourteen (31%) patients were treated with antiplatelet agents, 27 (60%) with anticoagulation, 7 (16%) with both antiplatelet and anticoagulation medications, and only 2 (4%) with stent angioplasty. The prognosis was complete recovery in 30 (86%) patients and mild focal neurological symptoms in 5 (14%).Postpartum cerebral arterial dissections are rare, and correct diagnosis relies on imaging examination. Prognosis is usually favorable in patients with early diagnosis and prompt treatment.

Abstract
A 35-year-old pregnant woman with mild migraine experienced thunderclap headache at 37 weeks of gestation. Her cerebral MRA showed arterial segmental narrowing of right middle cerebral artery and bilateral posterior cerebral artery. When admitted, she had no sign of eclampsia/preeclampsia. After 4 days, she had premature rupture of the membrane and gave birth by caesarean section. Caesarean section immediately resolved the headache. The postpartum course of the patient and her baby was uneventfull. One month after her onset, her cerebral MRA showed improvement in arterial segmental narrowing of cerebral artery. We diagnosed reversible cerebral vasoconstriction syndrome (RCVS) assoiated with pregnancy. Pregnancy-related RCVS develops primarily during the puerperal period, but our case was a rare case that developed just before delivery and was successful with aggressive intervention. When antepartum RCVS develops, early cesarean section with epidural anesthesia in parallel with active treatment for headache may lead to good outcomes for both mother and child.

Abstract
OBJECTIVES To investigate the epidemiologic and clinical characteristics of maternal near-misses attributable to haemorrhagic stroke (HS) occurring in patients with hypertensive disorders of pregnancy (HDP), with a focus on severe neurological morbidity. METHODS A national retrospective cohort study was conducted using the national database of health insurance claims for the period 2010 to 2017. The subjects were all insured women with a diagnosis of both HDP and HS. Severe neurological morbidity requiring rehabilitation, types of HDP, types of HS, and magnesium sulphate use were tabulated. RESULTS The number of women with HDP who were diagnosed with HS was 3.4 per 100,000 deliveries between 2010 and 2017. Forty percent of HDP-related HS cases had neurological morbidities requiring rehabilitation (1.4 per 100,000 deliveries), and 4.4% were in a persistent vegetative state after HS. Of the HDP cases who developed HS, 69.2% were severe HDP, of which 55.6% were without eclampsia. The most common type of HS was intracerebral haemorrhage (2.5 per 100,000 deliveries), followed by subarachnoid haemorrhage due to cerebral aneurysm (1.2 per 100,000 deliveries). The frequency of magnesium sulphate use increased in all patients with HDP-related HS in the second half of the study period (2014-2017) compared with the first half (2010-2013) (p < 0.0001). This was more evident in cases of HDP-related HS with eclampsia (31.9% to 83.8%) compared to those without eclampsia (25.0% to 42.9%). CONCLUSION Of the maternal near-miss cases due to HDP-related HS, 40.0% were rehabilitated and 69.2% were HDP without either eclampsia or severe hypertension.

Abstract
The incidence of maternal hemorrhagic stroke is elevated in women with preeclampsia during pregnancy. Panax ginseng is a traditional medicinal herb with numerous applications, and ginsenosides are the key bioactive compounds in Panax ginseng. This study aims to evaluate the effects of ginsenoside Rg2 on pregnancy outcomes and brain injury after intracerebral hemorrhage (ICH) in a rat model of preeclampsia. Preeclampsia was induced in rats by N(ω)-nitro-L-arginine methyl ester. Then, an ICH model was prepared by intrastriatal injection of bacterial collagenase. Ginsenoside Rg2 markedly elevated the survival ratio of fetuses. The placental and body weights were increased in the ginsenoside Rg2 group. Compared with the preeclampsia group, the Garcia test score of ginsenoside Rg2-treated rats was significantly increased. Ginsenoside Rg2 treatment ameliorated the ICH-induced augmentation of Evans blue extravasation, inhibited the ICH-induced elevation of brain water content, and reduced the interleukin-1β and tumor necrosis factor-α levels in the hemorrhagic hemisphere after ICH in preeclampsia model rats. Furthermore, ginsenoside Rg2 treatment not only inhibited augmentation of TLR-4, MyD88, p-IκBα, and p-NF-κB expression but also abated the reduction of occludin and claudin-5 expression in the hemorrhagic hemisphere. The findings indicated that ginsenoside Rg2 improved pregnancy outcomes in a rat model of preeclampsia without decreasing the blood pressure and urine protein level. The findings also demonstrated that ginsenoside Rg2 ameliorated ICH-induced neurological disorder and blood-brain barrier dysfunction in an animal model of preeclampsia by regulating the TLR4/NF-κB signaling pathway.

Abstract
The aim was to evaluate whether intra-hospital mortality from ischemic stroke is different in female patients. Methods. Studies were found in PubMed, Web of Science. We excluded 119 records because they did not include relevant reports or data. Studies were eligible for inclusion if enrolled adult patients with ischemic stroke and if the odds ratio (OR) of intra-hospital mortality in females compared to males is provided. Three retrospective cohort studies were eligible for inclusion criteria and so were included in the analysis. Findings: the random effect model showed a pooled significant higher risk of intra-hospital mortality [OR 1.34 (95% confidence interval 1.04, 1.74), P=0.026] in the female group compared to the male group. Our systematic review shows that intra-hospital mortality was significantly higher in female subjects compared to male.

Abstract
Maternal stroke occurs in around 34 out of every 100,000 deliveries and is responsible for around 5%-12% of all maternal deaths. It is most commonly hemorrhagic, and women are at highest risk for developing pregnancy-related hemorrhage during the early postpartum period through 6 weeks following the delivery. The most common causes of hemorrhagic stroke in pregnant patients are arteriovenous malformations and cerebral aneurysms. Management is similar to that for acute hemorrhagic stroke in the nonpregnant population with standard use of computed tomography and judicious utilization of intracranial vessel imaging and contrast. The optimal delivery method is evaluated on a case-by-case basis, and cesarean delivery is not always required. As most current studies are limited by retrospective design, relatively small sample sizes, and heterogeneous study term definitions, strong and comprehensive evidence-based guidelines on the management of acute hemorrhagic stroke in pregnant patients are still lacking. In the future, multicenter registries and prospective studies with uniform definitions will help improve management strategies in this complex patient population.

Front Physiol 2021; 12:686429. [PMID: 34220551 PMCID: PMC8242360 DOI: 10.3389/fphys.2021.686429] [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: 03/26/2021] [Accepted: 05/10/2021] [Indexed: 11/13/2022] Open
Abstract
The risk of postpartum (PP) stroke is increased in complicated pregnancies. Deficiency in CD4 T cell subsets is associated with preeclampsia and may contribute to PP vascular disease, including internal carotid artery (ICA) stenosis and stroke. We hypothesized that CD4 T cell deficiency in pregnancy would result in ICA dysregulation, including enhanced ICA vasoconstriction. We characterized the function, mechanical behavior, and structure of ICAs from C57BL/6 (WT) and CD4 deficient (CD4KO) mice, and assessed the role of NO in the control of ICA function at pre-conception and PP. WT and CD4KO mice were housed under pathogen-free conditions, mated to same-strain males, and allowed to litter or left virgin. At 3 days or 4 weeks PP, mice were euthanized. The responses to phenylephrine (PE), high K+ and acetylcholine (ACh) were assessed in pressurized ICAs before and after NOS inhibition. Passive lumen diameters were measured at 3–140 mmHg. eNOS and iNOS expression as well as the presence of T cells were evaluated by immunohistochemistry. Constriction of WT ICAs to PE was not modified PP. In contrast, responses to PE were significantly increased in ICAs from PP as compared to virgin CD4KO mice. Constriction to high K+ was not enhanced PP. ICAs from WT and CD4KO mice were equally sensitive to ACh with a significant rightward shift of dose-response curves after L-NNA treatment. NOS inhibition enhanced PE constriction of ICAs from WT virgin and PP mice. Although a similar effect was detected in ICAs of virgin CD4KO mice, no such changes were observed in vessels from PP CD4KO mice. Passive arterial distensibility at physiological levels of pressure was not modified at PP. ICA diameters were significantly increased in PP with no change in vascular wall thickness. Comparison of eNOS expression in virgin, 3 days and 4 weeks PP revealed a reduced expression in ICA from CD4 KO vs. WT PP vessels which reached significance at 4 weeks PP. iNos expression was similar and decreased over the PP period in vessels from WT and CD4KO mice. Dysregulation of the CD4 T cell population in pregnancy may make ICA vulnerable to vasospasm due to decreased NO-dependent control of ICA constriction. This may lead to cerebral hypoperfusion and increase the risk of maternal PP stroke.

Abstract
We report a case of ischemic stroke in an apparently healthy 35-year-old gravida 2 para 1 who was treated with tissue-type plasminogen activator (tPA) 9 hours after vaginal delivery that resulted in severe hemorrhage. Limited data suggest use of thrombolytics in pregnancy is safe, but there is a paucity of evidence assessing their use immediately postpartum. We describe successful combination of tPA with endovascular mechanical thrombectomy (EMT) for treatment of postpartum stroke, which was followed by extensive uterine bleeding.

Abstract
Despite adverse pregnancy outcomes for women with overweight or obesity, preconception guidelines for achieving optimal wellness for women contemplating pregnancy regarding the risks of overweight or obesity are varied based upon national affiliation. The aim of this study was to synthesize the best evidence related to preconception counseling and care focused on overweight or obesity provided to women of reproductive age. An integrative review of original studies was conducted. PubMed, Cumulative Index in Nursing and Allied Health Literature, Ovid, Scopus, Web of Science, and Embase were included. Full-text, data-based articles were searched from 2009 to 2018, with reviews and synthesis completed in 2019 and 2020. Of 8703 initial articles, 31 articles remained in the review. Quality assessment and level of evidence were evaluated based upon criteria from the Joanna Briggs Institute and the Johns Hopkins Nursing Evidence-Based Practice Quality Guide. The level of evidence for the majority of studies was non-experimental but they were of good quality with appropriate methods, samples and relevant results. Limited attention and interest in preconception counseling regarding risks of overweight or obesity by health care professionals were noted, which may contribute to women’s unawareness of these risks on preconception health.

Abstract
Background Reversible cerebral vasoconstriction syndrome is characterized by severe headache with reversible segmental constriction of the cerebral arteries. We present details on a patient with reversible cerebral vasoconstriction syndrome who initially visited an ophthalmologist because of visual symptoms. Case presentation A 34-year-old Japanese woman complained of sustained headache and insomnia starting 2 days after her first childbirth. In addition to the severe headache, a visual field defect was also observed 10 days later. Best corrected visual acuity at the initial visit was 20/20 and 20/25 for the right and left eye, respectively. Exudative retinal detachment was noted surrounding both optic heads. Visual field testing revealed left homonymous hemianopsia, while magnetic resonance imaging demonstrated the presence of edema and infarction of the bilateral basal nuclei and right occipital lobe. The homonymous hemianopsia and exudative retinal detachment recovered immediately after treatment with a free-radical scavenger and anticoagulant. There has been no recurrence of symptoms during the 4 years of follow-up. Conclusions We report a case of reversible cerebral vasoconstriction syndrome with ophthalmological symptoms that were reversible, including serous retinal detachment and homonymous hemianopsia.

Association between kidney stones and risk of developing stroke: a meta-analysis. Neurol Sci 2021; 42:4521-4529.

Abstract
Background Many studies have described the relationship between kidney stones and stroke, but the results are controversial, so we conducted this meta-analysis to estimate the relationship between kidney stones and the risk of developing stroke. Methods Studies were marked with a comprehensive search of PubMed, EMBASE, Google, and ISI Web of Science databases through 25 March 2020. Hazard ratios (HRs) and 95% confidence intervals (CIs) were extracted, and a random-effects model or fix-effects model was used to compute the pooled combined risk estimate. Heterogeneity was reported as I2. We performed subgroup and sensitivity analysis to assess potential sources of heterogeneity. Results Eight studies of seven articles involving 3,526,808 participants were included in the meta-analysis. Overall, kidney stones were associated with a moderate risk of stroke incidence (HR, 1.24; 95% CI, 1.11–1.40; I2=79.6%; p=0.000). We conducted a sensitivity analysis by removing the studies that had a high risk of bias. Heterogeneity subsequently decreased significantly, while an increased risk of stroke in patient with kidney stones was again demonstrated (HR, 1.16; 95% CI, 1.11–1.23; I2=28.7%; p=0.000). Stratifying analysis showed that the results were more pronounced for ischemic stroke (HR, 1.14; 95% CI, 1.08–1.22; I2=15.6%; p=0.00) and the follow-up duration ≥10 years (HR, 1.18; 95% CI, 1.10–1.27; I2=31.6%; p=0.003). Conclusions Our meta-analysis suggests that patients with kidney stones may have a modestly increased risk of developing stroke, especially in ischemic stroke. More large-scaled and clinical trials should be done to identify the relative impact of kidney stones on stroke outcomes in the future.

Abstract
INTRODUCTION The impact of pharmacovigilance activities on public health remains under-investigated, and measuring the impact on health of pharmacovigilance activities for a specific safety signal is challenging. OBJECTIVE To gain more insight into the methodological challenges and the data required, we assessed the impact of pharmacovigilance on public health for four identified product-specific safety signals using publicly available data in the Netherlands. The assessment was on the impact of the intertwined and complementary steps of the pharmacovigilance pathways. METHODS The impact of pharmacovigilance on public health was assessed using the assessment support tool and 'open data' from the Netherlands for four different types of pharmacovigilance safety signals: (1) off-label use of cyproterone acetate/ethinyloestradiol (CPA/EE) and thrombotic risk after pharmacovigilance measures after 2014; (2) pergolide and the risk of cardiac valvulopathy after pharmacovigilance activities in 2003; (3) proton pump inhibitors and the risk of hypomagnesaemia after pharmacovigilance activities in 2011; (4) rosiglitazone withdrawal from the market because of cardiovascular effects in 2010. RESULTS For the signals on CPA/EE and pergolide, a crude estimation of the impact could be made with varying degrees of assumptions based on the risk described in the literature and utilisation data. CONCLUSION This article highlights the methodological challenges and the data required to assess the impact of product-specific safety signals. A structured assessment support tool can be used as a guide for the necessary data elements and steps needed for the measurement or estimation of impact of pharmacovigilance activities on public health, provided that the appropriate data are available.

Abstract
Cerebral stroke is a leading global cause for mortality and disability. However, its pathogenesis is still unclear. Most tripartite motif (TRIM) family proteins, including TRIM62, have E3 ubiquitin ligase activities, and have multiple functions in regulating cellular processes. Nevertheless, the effects of TRIM62 on cerebral stroke still remain vague. Here, we reported that TRIM62 expression was markedly up-regulated in oxygen and glucose deprivation (OGD)-treated microglial cells. After cerebral ischemia, significantly elevated expression of TRIM62 was detected in peri-infarct area of wild type (WT) mice. The TRIM62 knockout (KO) mice exhibited alleviated apoptosis and neuroinflammation in the ischemic brain, eventually attenuating the stroke outcomes. Both in vitro and in vivo studies showed that nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome was dramatically activated in cerebral ischemia/reperfusion (I/R) conditions, while being ameliorated in TRIM62-KO mice, contributing to the suppression of neuroinflammatory response. Importantly, the in vitro experiments showed that OGD could induce the K63-ubiquitination of TRIM62 and the interaction between TRIM62 and NLRP3. In addition, adenovirus-regulated TRIM62 over-expression promoted the NLRP3 and nuclear factor κB (NF-κB) signaling, along with elevated interleukin-1β (IL-1β) and IL-18 transcriptional activities. Together, our results demonstrated that TRIM62 suppression was strongly protective in ischemic stroke through inhibiting NLRP3-regulated neuroinflammation.

Abstract
Developing clinically-focused evidence and experience-based approaches to improve maternity care is a national priority. Safety and quality collaborative initiatives related to management of hypertensive disorders of pregnancy are vital in the implementation of improved care. We reviewed the obstetric literature to construct a concise summary of the core pathophysiologic issues, practice principles and clinical interventions which are foundational for physicians providing immediate postpartum care for patients with severe pregnancy-related hypertension (including those with eclampsia, HELLP syndrome, and superimposed preeclampsia inclusive of those with gestational hypertension that develop severe range blood pressures). While based largely upon the American College of Obstetrics and Gynecology (ACOG) Hypertension Task Force Guidelines released in 2013 as well as updated 2018 guidelines set forth by ACOG for hypertensive disorders of pregnancy, this summary goes beyond the basic safety bundles for hypertension management and lays a pathophysiologic foundation for the immediate postpartum care of patients with severe hypertensive disorders of pregnancy.
