RESUMEN
BACKGROUND: Generalised pustular psoriasis (GPP) and palmoplantar pustulosis (PPP) are chronic, inflammatory skin conditions. Accumulating evidence shows that GPP and PPP have different characteristics compared with plaque psoriasis and are distinct clinical entities. OBJECTIVES: To assess the epidemiology, comorbidities, mortality and healthcare use for patients with GPP and PPP compared with those with plaque psoriasis in England. METHODS: A cohort study involving analyses of longitudinal electronic health record data in the Clinical Practice Research Datalink Aurum database and linked hospital and mortality data between 2008 and 2019. The primary study outcome was the incidence and prevalence rates for GPP, PPP and plaque psoriasis in England. Secondary outcomes included survival rates and healthcare resource use (HCRU) by disease type. RESULTS: We identified 373 patients with GPP, 1,828 with PPP and 224,223 with plaque psoriasis. The mean age was 55.9 years (standard deviation [SD]: 18.6) for patients with GPP, 51.5 years (SD: 16.4) for those with PPP, and 48.5 years (SD: 19.1) for those with plaque psoriasis; 62.5% and 65.9% of patients with GPP and PPP, respectively, were women, compared with 49.4% of those with plaque psoriasis. About half of the patients were overweight or obese at baseline (GPP, 48.6%; PPP, 56.0%; and plaque psoriasis, 45.9%). The incidence rates for GPP, PPP and plaque psoriasis were 0.25 (95% CI: 0.21-0.28), 2.01 (95% CI: 1.92-2.11) and 103.2 (95% CI: 102.5-103.9) per 100,000 person-years, respectively. From 2008 to 2019, the prevalence rates per 100,000 persons ranged from 1.61 to 3.0 for GPP, 1.1 to 18.7 for PPP and 1771.0 to 1903.8 for plaque psoriasis. Survival rates were lower for patients with GPP, particularly those who were over 55 years old and those with a history of ≥1 comorbidity in each cohort. HCRU was lower in the plaque psoriasis cohort and highest in the GPP cohort, particularly among those who had ≥1 GPP flare. CONCLUSIONS: Our results provide further evidence that GPP is a distinct disease with different epidemiology, lower survival and higher HCRU than plaque psoriasis in England.
RESUMEN
BACKGROUND: The pattern of surgical treatments for Idiopathic Intracranial Hypertension (IIH) in the United States is not well-studied, specifically the trend of utilizing endovascular venous stenting (EVS) as an emerging technique. METHODS: In this cross-sectional study, we aimed to explore the national trend of utilizing different procedures for the treatment of IIH including EVS, Optic Nerve Sheath Fenestration (ONSF), and CSF Shunting, with a focus on novel endovascular procedures. Moreover, we explored rates of 90-day readmission and length of hospital stay following different procedures, besides the effects of sociodemographic and clinical parameters on procedure choice. RESULTS: 36,437 IIH patients were identified from records between 2010 and 2018. Those in the EVS group were 29 years old on average, and 93.4 % were female. Large academic hospital setting was independently associated with higher EVS utilization, while other factors were not predictive of procedure choice. The proportion of EVS use in IIH hospitalizations increased significantly from 2010 to 2018 (P < 0.001), while there was a relative decline in the frequency of shunting procedures (P = 0.001), with ONSF utilization remaining stable (P = 0.39). The rate of 90-day readmission and length of hospital stay were considerably lower following EVS compared to other procedures (Ps < 0.001). CONCLUSION: This study presents novel population-level data on national trends in the frequency and outcome of EVS for IIH therapy. EVS was associated with shorter length of hospital stays and fewer readmission rates. In addition, a continuous increase in venous stenting compared to other procedures suggests an increasing role for endovascular therapies in IIH.

BACKGROUND: Influenza disproportionately affects individuals with underlying comorbidities. Long-term follow-up studies have shown that patients with cancer with influenza have higher mortality. However, very little is known about the in-hospital mortality and cardiovascular outcomes of influenza infection in cancer hospitalisations. METHODS: We compared the in-hospital mortality and cardiovascular outcomes in patients with cancer with and without influenza by screening the National Inpatient Sample from 2015 to 2017. A total of 9 443 421 hospitalisations with any cancer were identified, out of which 14 634 had influenza while 9 252 007 did not. A two-level hierarchical multivariate logistic regression analysis adjusted for age, sex, race, hospital type and relevant comorbidities was performed. RESULTS: The group with cancer and influenza had higher in-hospital mortality (OR 1.08; 95% CI 1.003 to 1.16; p=0.04), acute coronary syndromes (OR 1.74; 95% CI 1.57 to 1.93; p<0.0001), atrial fibrillation (OR 1.24; 95% CI 1.18 to 1.29; p<0.0001) and acute heart failure (OR 1.41; 95% CI 1.32 to 1.51; p<0.0001). CONCLUSION: Patients with cancer affected by influenza have higher in-hospital mortality and a higher prevalence of acute coronary syndrome, atrial fibrillation and acute heart failure.

Although health care delivery is becoming increasingly digitized, driven by the pursuit of improved access, equity, efficiency, and effectiveness, progress does not appear to be equally distributed across therapeutic areas. Oncology is renowned for leading innovation in research and in care; digital pathology, digital radiology, real-world data, next-generation sequencing, patient-reported outcomes, and precision approaches driven by complex data and biomarkers are hallmarks of the field. However, remote patient monitoring, decentralized approaches to care and research, "hospital at home," and machine learning techniques have yet to be broadly deployed to improve cancer care. In response, the Digital Medicine Society and Moffitt Cancer Center convened a multistakeholder roundtable discussion to bring together leading experts in cancer care and digital innovation. This viewpoint highlights the findings from these discussions, in which experts agreed that digital innovation is lagging in oncology relative to other therapeutic areas. It reports that this lag is most likely attributed to poor articulation of the challenges in cancer care and research best suited to digital solutions, lack of incentives and support, and missing standardized infrastructure to implement digital innovations. It concludes with suggestions for actions needed to bring the promise of digitization to cancer care to improve lives.

BACKGROUND: The incidence of cerebral venous thrombosis (CVT) in children of the United States is unknown, and it is uncertain how the burden of CVT hospitalizations in children changed over the last decade. METHODS: We conducted a retrospective cohort study using the State Inpatient Database and Kid's inpatient database. All new CVT cases in children (0-19 years) in the New York 2006 to 2018 State Inpatient Database (n=705), and all cases of CVT in the entire US contained in the 2006 to 2019 Kid's inpatient database (weighted n=6115) were identified using validated International Classification of Diseases (ICDs) codes. Incident counts were combined with census data to compute incidence. Between-group differences in incidence were tested using 2-proportions Z-test, and Joinpoint regression was used to trend incidence over time. RESULTS: Across the study period, 48.2% of all incident CVT cases and 44.6% of all CVT admissions nationally were in girls. Of all incident cases, 27.2% were infants and 65.8% of these infants were neonates. Average incidence across the study period was (1.1/100 000/year, SE:0.04) but incidence in infants (6.4/100 000/year) was at least 5 times the incidence in other age groups (1-4 years: 0.7/100 000/year, 15-19 years: 1.2/100 000/year). Incidence and national burden of CVT admissions was higher in girls in adolescents 15 to 19 years, but overall burden was higher in boys in other age groups. Age- and sex-standardized CVT incidence increased by 3.8% annually (95% CI, 0.2%-7.6%), while the overall burden of admissions increased by 4.9% annually (95% CI, 3.6%-6.2%). CONCLUSIONS: CVT incidence in New York and national burden of CVT increased significantly over the last decade.

PURPOSE: Studies on outcomes related to endovascular treatment (EVT) in advanced stages of chronic kidney disease (CKD) and end-stage renal disease (ESRD) among hospitalizations with acute limb ischemia (ALI) are limited. METHODS: The Nationwide Inpatient Sample was quarried from October 2015 to December 2017 to identify the hospitalizations with ALI and undergoing EVT. The study population was subdivided into 3 groups based on their CKD stages: group 1 (No CKD, stage I, stage II), group 2 (CKD stage III, stage IV), and group 3 (CKD stage V and ESRD). The primary outcome was all-cause in-hospital mortality. RESULTS: A total of 51 995 hospitalizations with ALI undergoing EVT were identified. The in-hospital mortality was significantly higher in group 2 (OR = 1.17; 95% CI 1.04 - 1.32, p=0.009) and group 3 (OR = 3.18; 95% CI 2.74-3.69, p<0.0001) compared with group 1. Odds of minor amputation, vascular complication, atherectomy, and blood transfusion were higher among groups 2 and 3 compared with group 1. Group 2 had higher odds of access site hemorrhage compared with groups 1 and 3, whereas group 3 had higher odds of major amputation, postprocedural infection, and postoperative hemorrhage compared with groups 1 and 2. Besides, groups 2 and 3 had lower odds of discharge to home compared with group 1. Finally, the length of hospital stay and cost of care was significantly higher with the advancing CKD stages. CONCLUSION: Advanced CKD stages and ESRD are associated with higher mortality, worse in-hospital outcomes and higher resource utilization among ALI hospitalizations undergoing EVT. CLINICAL IMPACT: Current guidelines are not clear for the optimum first line treatment of acute limb ischemia, especially in patients with advanced kidney disease as compared to normal/mild kidney disease patients. We found that advanced kidney disease is a significant risk factor for worse in-hospital morbidity and mortality. Furthermore, patients with acute limb ischemia and advanced kidney disease is associated with significantly higher resource utilization as compared to patients with normal/mild kidney disease. This study suggests shared decision making between treating physician and patients when considering endovascular therapy for the treatment of acute limb ischemia in patients with advanced kidney disease.

CONCLUSION: Patients with cancer affected by influenza have higher in-hospital mortality and a higher prevalence of acute coronary syndrome, atrial fibrillation and acute heart failure.
RESUMEN
INTRODUCTION: Hospital quality improvement and hospital performance are commonly evaluated using parameters such as average length of stay (LOS), patient safety measures and rates of hospital readmission. Thirty-day readmission (30-DR) rates are widely used as a quality indicator and a quantifiable metric for hospitals since patients are often readmitted for the exacerbation of conditions from index admission. The quality of patient education and postdischarge care can influence readmission rates. We report the 30-DR rates of patients with asthma using a national dataset for the year 2013. OBJECTIVES: The aim of our study was to assess the 30- day readmission (30-DR) rate as well as, the causes and predictors of readmissions. STUDY DESIGNS/METHODS: Using the Nationwide Readmission Database (NRD) (2013), we identified primary discharge diagnoses of asthma by using International Classification of Diseases, Ninth Revision, Clinical Modification code '493'. Categorical and continuous variables were assessed by a χ2 test and a Student's t-test, respectively. The independent predictors of unplanned 30-DR were detected by multivariate analysis. We used sampling weights, which are provided in the NRD, to generate the national estimates. RESULTS: There were 130 490 (weighted N=311 173) inpatient asthma admissions during 2013. The overall 30-DR for asthma was 11.9%. The associated factors for 30-DR were age 45-84 years (40.32% vs 29.05%; p<0.001), enrolment in Medicare (49.33% vs 30.61% p<0.001), extended LOS (mean, 4.40±0.06 vs 3.25±0.04 days; p<0.001), higher mean cost (US$8593.91 vs US$6741.31; p<0.001) and higher disposition against medical advice (DAMA) (4.14% vs 1.51%; p<0.001). The factors that increased the chance of 30-DR were advanced age (≥45-64 vs ≤17 years; OR 4.61, 95% CI 4.04 to 5.27, p<0.0001), male sex (OR 1.19, 95% CI 1.13 to 1.26, p<0.0001), a higher Charlson Comorbidity Index (CCI) (OR 1.16, 95% CI 1.14 to 1.18, p<0.0001), DAMA (OR 2.32, 95% CI 2.08 to 2.59, p<0.0001), non-compliance with medication (OR 1.34, 95% CI 1.24 to 1.46, p<0.0001), post-traumatic stress disorder (OR 1.48, 95% CI 1.22 to 1.79, p<0.0001), alcohol use (OR 1.45, 95% CI 1.27 to 1.65, p<0.0001), gastro-oesophageal reflux disease (OR 1.20, 95% CI 1.14 to 1.27, p<0.0001), obstructive sleep apnoea (OR 1.11, 95% CI 1.03 to 1.18, p<0.0042) and hypertension (OR 1.11, 95% CI 1.06 to 1.17, p<0.0001). CONCLUSIONS: We found that the overall 30-DR rate for asthma was 11.9% all-cause readmission. Major causes of 30-DR were asthma exacerbation (36.74%), chronic obstructive pulmonary disease (11.47%), respiratory failure (6.46%), non-specific pneumonia (6.19%), septicaemia (3.61%) and congestive heart failure (3.32%). One-fourth of the revisits occurred in the first week, while half of the revisits took place in the first 2 weeks. Education regarding illness and the importance of medicine compliance could play a significant role in preventing asthma-related readmission.

OBJECTIVE: The authors sought to analyze a large, publicly available, nationwide hospital database to further elucidate the impact of cardiopulmonary arrest (CA) in association with subarachnoid hemorrhage (SAH) on short-term outcomes of mortality and discharge disposition. METHODS: This retrospective cohort study was conducted by analyzing de-identified data from the National (Nationwide) Inpatient Sample (NIS). The publicly available NIS database represents a 20% stratified sample of all discharges and is powered to estimate 95% of all inpatient care delivered across hospitals in the US. A total of 170,869 patients were identified as having been hospitalized due to nontraumatic SAH from 2008 to 2014. RESULTS: A total of 5415 patients (3.2%) were hospitalized with an admission diagnosis of CA in association with SAH. Independent risk factors for CA included a higher Charlson Comorbidity Index score, hospitalization in a small or nonteaching hospital, and a Medicaid or self-pay payor status. Compared with patients with SAH and not CA, patients with CA-SAH had a higher mean NIS Subarachnoid Severity Score (SSS) ± SD (1.67 ± 0.03 vs 1.13 ± 0.01, p < 0.0001) and a vastly higher mortality rate (82.1% vs 18.4%, p < 0.0001). In a multivariable model, age, NIS-SSS, and CA all remained significant independent predictors of mortality. Approximately 18% of patients with CA-SAH survived and were discharged to a rehabilitation facility or home with health services, outcomes that were most predicted by chronic disease processes and large teaching hospital status. CONCLUSIONS: In the largest study of its kind, CA at onset was found to complicate roughly 3% of spontaneous SAH cases and was associated with extremely high mortality. Despite this, survival can still be expected in approximately 18% of patients.

BACKGROUND: Carotid web (CaW) is non-atheromatous, shelf-like intraluminal projection, generally affecting the posterolateral wall of the proximal internal carotid artery, and associated with embolic stroke, particularly in younger patients without traditional stroke risk factors. Treatment options for symptomatic CaWs include interventional therapy with carotid endarterectomy or carotid stenting versus medical therapy with antiplatelet or anticoagulants. As safety and efficacy of these approaches have been incompletely delineated in small-to-moderate case series, we performed a systematic review of outcomes with interventional and medical management. METHODS: Systematic literature search was conducted and data analyzed per PRISMA guidelines (Preferred Reporting Items for Systemic Reviews and Meta-Analyses) from January 2000 to October 2021 using the search strategy: "Carotid web" OR "Carotid shelf" OR "Web vessels" OR "Intraluminal web". Patient-level demographics, stroke risk factors, technical procedure details, medical and interventional management strategies were abstracted across 15 series. All data were analyzed using descriptive statistics. RESULTS: Among a total of symptomatic 282 CaW patients across 14 series, age was 49.5 (44-55.7) years, 61.7% were women, and 76.6% were black. Traditional stroke risk factors were less frequent than the other stroke causes, including hypertension in 28.6%, hyperlipidemia 14.6%, DM 7.0%, and smoking 19.8%. Thrombus adherent to CaW was detected on initial imaging in 16.2%. Among 289 symptomatic CaWs across 15 series, interventional management was pursued in 151 (52.2%), carotid artery stenting in 87, and carotid endarterectomy in 64; medical management was pursued in 138 (47.8%), including antiplatelet therapy in 80.4% and anticoagulants in 11.6%. Interventional and medical patients were similar in baseline characteristics. The reported time from index stroke to carotid revascularization was median 14 days (IQR 9.5-44). In the interventional group, no periprocedural mortality was noted, major periprocedural complications occurred in 1/151 (0.5%), and no recurrent ischemic events were observed over follow-up range of 3-60 months. In the medical group, over a follow-up of 2-55 months, the recurrence cerebral ischemia rate was 26.8%. CONCLUSION: Cumulative evidence from multiple series suggests that carotid revascularization is a safe and effective option for preventing recurrent ischemic events in patients with symptomatic carotid webs.

OBJECTIVE: To describe age and sex-specific prevalence of cancer in acute ischemic stroke (AIS) hospitalizations in the United States over the last decade. METHODS: We conducted a retrospective serial cross-sectional study using all primary AIS discharges (weighted n=5,748,358) with and without cancer in the 2007-2019 National Inpatient Sample. Admissions with primary central nervous system cancers were excluded. Joinpoint regression was used to compute the average annualized percentage change (AAPC) in cancer prevalence over time. RESULTS: Across the study period, 12.7% of AIS admissions had previous/active cancer, while 4.4% had active cancer. Of these, 18.8% were hematologic cancers, 47.2% were solid cancers without metastasis and 34.0% were metastatic cancers of any type. Age-adjusted active cancer prevalence differed by sex (males:4.8%; females:4.0%) and increased with age up to age 70-79 years (30-39 years 1.4%; 70-79 years:5.7%). Amongst cancer admissions, lung (18.7%) and prostate (17.8%) were the most common solid cancers in men, while lung (19.6%) and breast (13.7%) were the most prevalent in women. Active cancer prevalence increased over time (AAPC 1.7%, p<0.05) but the pace of increase was significantly faster in women (AAPC 2.8%) compared to men (AAPC 1.1%) (p-comparison =0.003). Fastest pace of increased prevalence was seen for genitourinary cancers in women and for gastrointestinal cancers in both sexes. Genitourinary cancers in men declined over time (AAPC -2.5%, p<0.05). Lung cancer prevalence increased in women (AAPC 1.8%, p<0.05) but remained constant in men. Prevalence of head/neck, skin/bone, gastrointestinal, hematological and metastatic cancers increased over time at similar pace in both sexes. CONCLUSION: Prevalence of cancer in AIS admissions increased in the US over the last decade but the pace of this increase was faster in women compared to men. Gastrointestinal cancers in both sexes and genitourinary cancers in women are increasing at the fastest pace. Additional studies are needed to determine whether this increase is from co-occurrence or causation of AIS by cancer.

INTRODUCTION: The real-world evolution of management and outcomes of patients with unruptured brain arteriovenous malformations (AVMs) has not been well-delineated following the ARUBA trial findings of no general advantage of initial interventional (surgical/endovascular/radiotherapy) vs. initial conservative medical therapy. METHODS: We analyzed the National Inpatient Sample from 2009-2018, capturing 20% of all admissions in the U.S. Validated ICD-9 and -10 codes defined brain AVMs, comorbidities, and the use of interventional modalities. Analyses were performed by year and for the dichotomized periods of pre-ARUBA (2009-2013) vs. post-ARUBA (2014-2018). RESULTS: Among the national projected 88,037 AVM admissions, 72,812 (82.7%) were unruptured AVMs and 15,225 (17.3%) were ruptured AVMs. Among uAVMs, 51.4% admitted pre-ARUBA and 48.6% in post-ARUBA period. The post-ARUBA patients were mildly older (median age 53.3 vs. 51.8 (p = 0.001) and had more comorbidities including hypertension, diabetes, obesity, renal impairment, and smoking. Before the first platform report of ARUBA (2009-2012), rates of use of interventional treatments during uAVM admissions trended up from 31.8% to 35.4%. Thereafter, they declined significantly to 26.4% in 2018 (p = 0.02). The decline was driven by a reduction in the frequency of endovascular treatment from 18.8% to 13.9% and inpatient stereotactic radiosurgery from 0.5% to 0.1%. No change occurred in the frequency of microsurgery or combined endovascular and surgical approaches. Adjusted multivariable model of uAVMs showed increased odds of discharge to a long-term inpatient facility or in-hospital death [OR 1.14 (1.02-1.28), p = 0.020] in post-ARUBA. A significantly increased proportion of ruptured AVMs from 17.0% to 23.3% was observed consistently in post-ARUBA. CONCLUSION: Nationwide practice in the management of unruptured AVMs changed substantially with the publication of the ARUBA trial in a durable and increasing manner. Fewer admissions with the interventional treatment of unruptured AVMs occurred, and a corresponding increase in admission for ruptured AVMs transpired, as expected with a strategy of watchful waiting and treatment only after an index bleeding event. Further studies are needed to determine whether these trends can be considered to be ARUBA trial effect or are merely coincidental.

BACKGROUND: Primary angiitis of the central nervous system (PACNS) is a relapsing-remitting disease with a heterogeneous course. Case series have delineated the long-term disease course but not acute outcomes or their determinants. The national United States hospital burden of PACNS has not been quantified. METHODS: Analysis of the United States Nationwide Readmissions Database (2016-2018) to characterize the frequency of PACNS hospitalizations, demographic features, inpatient mortality, and discharge outcomes. RESULTS: During the 3-year study period, unweighted 1843 (weighted 3409) patients with PACNS were admitted to the 1078 Healthcare Cost and Utilization Project HCUP participating hospitals; with weighting, this value indicates that 1136 patients were admitted each year to US hospitals, representing yearly 0.01 cases per 100 000 national hospitalizations. The majority of patients were hospitalized in metropolitan teaching hospitals (81.6%). The median age at admission was 54.9 (IQR: 44.0-66.5) years and 59.4% were women. Neurologic manifestations included ischemic stroke in 38.2%, transient ischemic attack in 20.2%, seizure disorder in 22.8%, and intracranial hemorrhage in 13.0%. Overall, 60.0% of patients were discharged home, 35.0% discharged to a rehabilitation facility or nursing home and 5.0% died before discharge. Patient features independently associated with the discharge to another facility or death included older age (odds ratio [OR], 1.03 [95% CI, [1.03-1.04]]), male sex (OR, 1.22 [1.04-1.43]), intraparenchymal hemorrhage (OR, 1.41 [1.08-1.84]), ischemic stroke (OR, 2.79 [2.38-3.28]), and seizure disorder (OR, 1.57 [1.31-1.89]). CONCLUSION: Our study showed PACNS is still a rare inflammatory disorder of the blood vessels of the central nervous system suggesting an annual hospitalization of 5.1 cases per 1,000,000 person-years in the more diverse and contemporary US population. Overall, 4 in 10 had unfavorable discharge outcome, being unable to be discharged home, and 1 in 20 died before discharge.

BACKGROUND AND PURPOSE: Pulmonary arteriovenous fistulas (PAVFs) are a treatable cause of acute ischemic stroke (AIS), not mentioned in current American Heart/Stroke Association guidelines. PAVFs are recognized as an important complication of hereditary hemorrhagic telangiectasia. METHODS: The prevalence of PAVF and hereditary hemorrhagic telangiectasia among patients admitted with AIS in the United States (2005-2014) was retrospectively studied, utilizing the Nationwide Inpatient Sample database. Clinical factors, morbidity, mortality, and management were compared in AIS patients with and without PAVF/hereditary hemorrhagic telangiectasia. RESULTS: Of 4 271 910 patients admitted with AIS, 822 (0.02%) were diagnosed with PAVF. Among them, 106 of 822 (12.9%) were diagnosed with hereditary hemorrhagic telangiectasia. The prevalence of PAVF per million AIS admissions rose from 197 in 2005 to 368 in 2014 (Ptrend, 0.026). Patients with PAVF were younger than AIS patients without PAVF (median age, 57.5 versus 72.5 years), had lower age-adjusted inpatient morbidity (defined as any discharge other than home; 39.6% versus 46.9%), and had lower in-hospital case fatality rates (1.8% versus 5.1%). Multivariate analyses identified the following as independent risk markers (odds ratio [95% CI]) for AIS in patients with PAVF: hypoxemia (8.4 [6.3-11.2]), pulmonary hemorrhage (7.9 [4.1-15.1]), pulmonary hypertension (4.3 [4.1-15.1]), patent foramen ovale (4.2 [3.5-5.1]), epistaxis (3.7 [2.1-6.8]), venous thrombosis (2.6 [1.9-3.6]), and iron deficiency anemia (2 [1.5-2.7]). Patients with and without PAVF received intravenous thrombolytics at a similar rate (5.9% versus 5.8%), but those with PAVF did not receive mechanical thrombectomy (0% versus 0.7%). CONCLUSIONS: Pulmonary arteriovenous fistula-related ischemic stroke represents an important younger demographic with a unique set of stroke risk markers, including treatable conditions such as causal PAVFs and iron deficiency anemia.

BACKGROUND AND PURPOSE: Reversible cerebral vasoconstriction syndrome (RCVS) is a well-established cause of stroke, but its demographics and outcomes have not been well delineated. METHODS: Analysis of the United States Nationwide Inpatient Sample database (2016-2017) to characterize the frequency of hospitalizations for RCVS, demographic features, inpatient mortality, and discharge outcomes. RESULTS: During the 2-year study period, 2020 patients with RCVS were admitted to Nationwide Inpatient Sample hospitals, representing 0.02 cases per 100 000 national hospitalizations. The mean age at admission was 47.6 years, with 85% under 65 years of age, and 75.5% women. Concomitant neurological diagnoses during hospitalization included ischemic stroke (17.1%), intracerebral hemorrhage (11.0%), subarachnoid hemorrhage (32.7%), seizure disorders (6.7%), and reversible brain edema (13.6%). Overall, 70% of patients were discharged home, 29.7% discharged to a rehabilitation facility or nursing home and 0.3% died before discharge. Patient features independently associated with the poor outcome of discharge to another facility or death were advanced age (odds ratio [OR], 1.04 [95% CI, 1.03-1.04]), being a woman (OR, 2.45 [1.82-3.34]), intracerebral hemorrhage (OR, 2.91 [1.96-4.31]), ischemic stroke (OR, 5.72 [4.32-7.58]), seizure disorders (OR, 2.61 [1.70-4.00]), reversible brain edema (OR, 6.26 [4.41-8.89]), atrial fibrillation (OR, 2.97 [1.83-4.81]), and chronic kidney disease (OR, 3.43 [2.19-5.36]). CONCLUSIONS: Projected to the entire US population, >1000 patients with RCVS are hospitalized each year, with the majority being middle-aged women, and about 300 required at least some rehabilitation or nursing home care after discharge. RCVS-related inpatient mortality is rare.

Background and Purpose: IV tPA (intravenous thrombolysis with alteplase) and mechanical thrombectomy (MT) utilization increased in acute ischemic stroke hospitalizations in the United States over the last decade. It is uncertain whether this increase occurred equally across all age, sex, and racial groups. Methods: Adult acute ischemic stroke hospitalizations (weighted n=4 442 657) contained in the 2008 to 2017 National Inpatient Sample were identified using International Classification of Diseases codes. Proportions of hospitalizations with IV tPA and MT were computed according to age, sex, and race. Joinpoint and multivariable-adjusted logistic regression models were used to evaluate trends over time. Results: Across this period, 32.4% of all hospitalizations were in patients ≥80 years, and 64.7% of these were women. IV tPA and MT use differed by age with highest proportion of utilization of both treatments in patients aged 18 to 39 years (IV tPA, 12.3%) and lowest percentage in patients aged ≥90 years (IV tPA, 7.9%). Utilization of both procedures increased over time in all age groups, but the pace of increase was faster in patients ≥90 years compared with patients aged 18 to 39 years (MT: odds ratio, 1.25 [95% CI, 1.201.35] per unit increase in year, P interaction <0.001). Frequency of utilization of IV tPA and MT was lower in Black patients compared with White patients in most age groups. Usage of both procedures increased over time in all races and after 2015, IV tPA utilization was >10% in all demographic subgroups except in Black patients 60 to 79 years and Black patients ≥80 years. Analysis of race-by-time interaction revealed the Black-vs-White treatment gaps for IV tPA (odds ratio, 1.02 [95% CI, 1.011.03]) and MT (odds ratio, 1.08 [95% CI,1.051.12]) declined over time (both P interaction <0.01). Sex-related differences in IV tPA use were noted, but this gap also declined over time. Conclusions: Age- and sex-related treatment gaps in IV tPA and MT reduced over the last decade. Racial disparity in IV tPA and MT utilization persists with particularly lower frequency of usage of both acute stroke treatments in Black patients compared with White patients, but race-associated treatment gaps also declined over time.

Pulmonary arteriovenous malformations (PAVMs) are pathologic low-resistance conduits between a pulmonary artery and vein. Over 80% PAVMs occur in patients with hereditary hemorrhagic telangiectasia (HHT) and result from mutations in the transforming growth factor-beta signaling pathway. Mutations in the Growth Differentiation Factor 2 (GDF2) gene have recently been described to result in a vascular-anomaly syndrome with phenotypic overlap with HHT. We report a 43-year-old woman with a PAVM related ischemic stroke who was subsequently found to have a novel GDF2 gene mutation. The patient underwent coil-embolization of the PAVM with stable clinical and radiographic follow-up. It is important to diagnose PAVMs as they are an important cause of stroke-in-young; and can be treated definitively, reducing risk of recurrent stroke and migraine.

Severe acute respiratory syndrome coronavirus (SARS-CoV-2) is responsible for an unprecedented worldwide pandemic that has severely impacted the United States. As the pandemic continues, a growing body of evidence suggests that infected patients may develop significant coagulopathy with resultant thromboembolic complications including deep vein thrombosis, pulmonary embolism, myocardial infarction, and ischemic stroke. However, this data is limited and comes from recent small case series and observational studies on stroke types, mechanisms, and outcomes.1-14 Furthermore, evidence on the role of therapeutic anticoagulation in SARS-CoV-2 infected patients with elevated inflammatory markers, such as D-dimer, is also limited. We report the case of a middle-aged patient who presented with a large vessel ischemic stroke likely resulting from an underlying inflammatory response in the setting of known novel coronavirus infection (COVID-19). Histopathologic analysis of the patient's ischemic brain tissue revealed hypoxic neurons, significant edema from the underlying ischemic insult, fibrin thrombi in small vessels, and fibroid necrosis of the vascular wall without any signs of vasculature inflammation. Brain biopsy was negative for the presence of SARS-CoV-2 RNA (RT-PCR assay). Along with a growing body of literature, our case suggests that cerebrovascular thromboembolic events in COVID-19 infection may be related to acquired hypercoagulability and coagulation cascade activation due to the release of inflammatory markers and cytokines, rather than virus-induced vasculitis. Further studies to investigate the mechanism of cerebrovascular thromboembolic events and their prevention is warranted.

Oxytocin influences social behaviour and hypothalamic-pituitary-adrenal (HPA) function. We previously found that social instability stress (SS) from postnatal day 30 to 45 increased oxytocin receptor (OTR) densities in the lateral septum and nucleus accumbens of adolescent male rats. Here, we investigated social behaviour and HPA function in adolescent male SS rats compared with age- and sex-matched controls after intraperitoneal treatment with an OTR antagonist L-368,899 (OTR-A). Regardless of OTR antagonism, adolescent SS rats spent more time in social approach (investigation through wire mesh) but less time in social interaction (physical interaction) with unfamiliar same-sex and same-age peers than did controls. However, OTR-A-treatment caused SS rats to be more socially avoidant than OTR-A-treated controls and saline-treated rats of the same condition. Additionally, the predicted rise in plasma corticosterone in response to OTR-A treatment was blunted in SS rats. Fos immunoreactivity (IR) was used as a marker of neural activation in social brain regions and oxytocin-IR was examined in the paraventricular nucleus of the hypothalamus (PVN) in response to interacting with unfamiliar peers in SS and control rats after OTR-A treatment. OTR-A treatment had little effect on Fos-IR and oxytocin-IR in the analyzed brain regions, but SS rats had lower Fos-IR and oxytocin-IR in the PVN and greater Fos-IR in subregions of the prefrontal cortex, and hippocampus, and lateral septum than did controls. Finally, binding density of OTR was measured in the PVN and hippocampus, and greater OTR binding density was found in the PVN of SS rats. Together, these data demonstrate a greater influence of OTR antagonism on social behaviour and a reduced influence of OTR antagonism on HPA responses after adolescent SS in male rats. The results also suggest that differences in neural functioning in the prefrontal cortex, hippocampus and lateral septum of adolescent SS rats may be involved in their altered social behaviour relative to that of controls.
