Objectives Several brain and spinal magnetic resonance imaging signs have been described in spontaneous intracranial hypotension. Their correlations are not fully studied. This study aimed to explore potential mechanisms underlying cerebral neuroimaging findings and to examine associations among spinal and brain magnetic resonance imaging signs. Methods We conducted a retrospective review of magnetic resonance myelography and brain magnetic resonance imaging records of patients with spontaneous intracranial hypotension. Categorical principal component analysis was employed to cluster brain neuroimaging findings. Spearman correlation was employed to analyze associations among different brain neuroimaging findings and between brain and spinal neuroimaging findings. Results In patients with spontaneous intracranial hypotension (n = 148), categorical principal component analysis of brain neuroimaging signs revealed two clusters: Cerebral venous dilation and brain descent. Among all brain magnetic resonance imaging signs examined, only midbrain-pons angle associated with anterior epidural cerebrospinal fluid collection length (surrogate spinal cerebrospinal fluid leak severity) (n = 148, Spearman’s ρ = −0.38, p < .001). Subgroup analyses showed that the association between midbrain-pons angle (within brain descent cluster) and spinal cerebrospinal fluid leak severity was presented in patients with convex margins of the transverse sinuses (n = 122, Spearman’s ρ = −0.43, p < .001), but not in patients without convex margins (n = 26, Spearman’s ρ = −0.19, p = .348). The association between severity of transverse sinus distension and spinal cerebrospinal fluid leak severity was only presented in patients without convex margins (n = 26, Spearman’s ρ = 0.52, p = .006). Conclusion This study indicates that there are two factors behind the brain neuroimaging findings in spontaneous intracranial hypotension: Cerebral venous dilation and brain descent. Certain brain neuroimaging signs correlate with spinal cerebrospinal fluid leakage severity, depending on different circumstances.
Revisiting Bergmann’s Occupational Crowding Model
Authors: Holder Michelle 
Published: October 2018

In 1971, economist Barbara Bergmann developed the “occupational crowding model,” which posited that black men are “crowded into” low-wage occupations and “crowded out” of high-wage occupations due to employer discrimination. In quantitative analyses I have conducted for the years 2010 through 2011, the results have yielded a different picture from what Bergmann’s model predicts: although African American men are underrepresented in high-wage occupations, consistent with her model, this group does not appear to be overrepresented in low-wage occupational categories when the level of analysis is between major low-wage occupational categories instead of within categories. I attribute this to demographic changes in the US labor force, and conclude by suggesting that the model now requires further specification. JEL Codes: J15, J62, J71
On the Margins of Death: A Scoping Review on Palliative Care and Schizophrenia
Authors: Relyea Erin , MacDonald Brooke , Cattaruzza Christina , Marshall Denise 
Published: October 2018

Schizophrenia is a serious chronic mental illness that results in marginalization and stigma for sufferers. It is the seventh leading cause for disability worldwide. The symptoms of the illness, including hallucinations, delusions, and extremely disordered thinking and behavior, may also introduce barriers to accessing treatment, education, housing, and employment. Little is known about end-of-life care for individuals with schizophrenia. To address this gap, a scoping review was conducted to enhance understanding of hospice and palliative care for patients with schizophrenia. From this scoping review, 342 unique titles and abstracts were identified through a search of 20 databases, including 11 social science databases, 6 medical databases, and 3 gray literature databases. A total of 32 articles met the inclusion criteria and the following 4 themes were identified: Stigma affecting quality of care and access to care; Issues related to consent and capacity for the patient’s end-of-life care decisions and to appoint substitute decision makers; Best practices for psychosocial interventions, pharmacology, family and health-care collaborations, goals of care, setting, and smoking; and Barriers to care, including setting, communication, provider education, and access to care. The review suggests the importance of mandatory interdisciplinary training practices and policy standards outlining cooperative communication across health-care providers. It highlights gaps in evidence-based research on psychosocial interventions and collaborative frameworks to enable the provision of quality end-of-life care for individuals with schizophrenia.

Introduction We examined the clinical relevance of urinary concentrations of B-cell–activating factor of the tumour necrosis factor family (BAFF) and a proliferation-inducing ligand (APRIL) in systemic lupus erythematosus (SLE). Methods We quantified urinary BAFF (uBAFF) by enzyme-linked immunosorbent assay in 85 SLE, 28 primary Sjögren syndrome (pSS), 40 immunoglobulin A nephropathy (IgAN) patients and 36 healthy controls (HCs). Urinary APRIL (uAPRIL) and monocyte chemoattractant protein 1 (uMCP-1) were also quantified. Overall and renal SLE disease activity were assessed using the Systemic Lupus Erythematosus Disease Activity Index 2000. Results uBAFF was detected in 12% (10/85) of SLE patients, but was undetectable in HCs, IgAN and pSS patients. uBAFF was detectable in 28% (5/18) of SLE patients with active nephritis vs 5/67 (7%) of those without ( p = 0.03), and uBAFF was significantly higher in active renal patients ( p = 0.02) and more likely to be detected in patients with persistently active renal disease. In comparison, uAPRIL and uMCP-1 were detected in 32% (25/77) and 46% (22/48) of SLE patients, respectively. While no difference in proportion of samples with detectable uAPRIL was observed between SLE, HCs and IgAN patients, both uAPRIL and uMCP-1 were significantly detectable in higher proportions of patients with active renal disease. Conclusions uBAFF was detectable in a small but a significant proportion of SLE patients but not in other groups tested, and was higher in SLE patients with active renal disease.
Catering to the Whole Spectrum of Dividends: Evidence from the Taiwan Stock Market
Authors: Teng Chia-Chen, , Liu Victor W. 
Published: October 2018

This study examines the presence of catering for various dividend policies in Taiwanese firms, including cash, stock and dual dividends. Different from prior results in the literature, we find that the catering phenomenon exists for these three types of dividend decisions. When one type of dividend premium (i.e., cash dividend) is high, managers are more likely to issue the same type of dividend and less likely to issue the other type of dividend (i.e., stock dividend). Catering persists even after controlling for the effects of a firm’s characteristics, risk and external policy, as well as macroeconomic situations. JEL Classification: G35, C23

Background: Although home hospice organizations provide essential care for and support to terminally ill patients, many day-to-day caregiving responsibilities fall to informal (ie, unpaid) caregivers. Studies have shown that caregivers value receiving clear information about end-of-life (EoL) care. Meeting the information needs of this group is critical in improving their experience in hospice. Objectives: To identify the information needs of informal home hospice caregivers. Design: One hundred five semi-structured phone interviews with informal caregivers were conducted. Study data were analyzed using a standard qualitative method (ie, content analysis). Participants: Informal home hospice caregivers whose loved ones have been discharged (death or live discharge) from an urban, nonprofit hospice organization. Measured: Participants’ information needs were ascertained by assessing whether information regarding hospice was or was not fully explained or whether there was information they wished they knew prior to the hospice transition. Results: Among study participants, 48.6% had unmet information needs related to (1) general information about hospice (n = 17, 16.2%), (2) what to expect at the EoL (n = 19, 18.1%), and (3) support provided by hospice (n = 30, 28.6%). Specifically, caregivers expressed the need for more information on what hospice is, caring for a dying patient, and the day-to-day care hospice provides. Conclusion: Our study indicates that approximately half of the informal caregivers had unmet information needs. Further research is needed to identify efficacious strategies to best meet the information needs of this group. Specific topics that need emphasis include what hospice care is, what to expect at the EoL, and what level of support hospice offers.

Purpose: Preservatives in glaucoma medications have been associated with ocular toxicity. We compared ocular signs and symptoms in patients with open-angle glaucoma or ocular hypertension treated in monotherapy with preserved or preservative-free prostaglandin analogues. Methods: Observational cross-sectional clinical study in real life. 82 patients treated for at least 6 months with prostaglandin analogue were assessed for intraocular pressure, ocular symptoms and ocular signs including conjunctival hyperaemia, tear break-up time and tear meniscus height measured using objective and non-invasive methods (OCULUS Keratograph 5M). Patients presenting with symptoms of ocular toxicity with preserved prostaglandin analogues were switched to preservative-free latanoprost, and a second assessment was processed 6 months after. Results: At inclusion, 30 (36.6%) patients were treated with preservative-free latanoprost, 25 (30.5%) with preserved latanoprost, 16 (19.5%) with preserved travoprost and 11 (13.4%) with preserved bimatoprost. Patients treated with preservative-free latanoprost reported significantly less ocular symptoms upon instillation (mainly burning) and between instillations than patients treated with preserved prostaglandin analogues. The mean conjunctival hyperaemia (limbal + bulbar) was significantly lower with preservative-free latanoprost (2.08 ± 0.55) compared to preserved latanoprost (2.50 ± 0.7, p = 0.0085), preserved travoprost (2.67 ± 0.82, p = 0.0083) and preserved bimatoprost (2.68 ± 0.67, p = 0.0041). There were no relevant between-group differences in mean tear meniscus height and break-up time. Ocular symptoms and conjunctival hyperaemia improved when preserved prostaglandin analogues were switched to preservative-free latanoprost for 6 months while intraocular pressure reduction was maintained. Conclusion: Overall, this study suggests a better subjective and objective ocular tolerance when patients were treated with preservative-free latanoprost than with other preserved prostaglandin analogues monotherapy. Switching to preservative-free latanoprost maintained intraocular pressure at the same level as preservative prostaglandin analogue, but improved ocular surface tolerance.

Background Patients with a sudden onset of focal neurological deficits consistent with stroke, who turn out to have alternative conditions, have been labeled stroke mimics. Aims We assessed a recently validated telemedicine-based stroke mimic score (TeleStroke mimic score; TM-score) and individual patient characteristics with regard to its discriminative value between cerebrovascular disease and stroke mimic patients in the in-person, pre-hospital setting. Methods We evaluated patients cared for in a mobile stroke unit in Berlin, Germany. We investigated whether the TM-score (comprising six parameters), Face Arm Speech Time test, and individual patient characteristics were able to differentiate cerebrovascular disease from stroke mimic patients. Results We included 423 patients (299 (70.7%) cerebrovascular disease and 124 (29.3%) stroke mimic) in the final analysis. A TM-score > 30 indicated a high probability of a cerebrovascular disease and a score ≤15 of a stroke mimic. The TM-score performed well to identify stroke mimics (area under the curve of 0.74 under receiver-operating characteristic curve analysis). The cerebrovascular disease patients were older (74.8 vs. 69.8 years, p = 0.001), had more often severe strokes (NIHSS > 14 25.8% vs. 11.3%, p = 0.001), presented more often with weakness of the face (70.9% vs. 42.7%, p = 0.001) or arm (60.9% vs. 33.9%, p = 0.001), dysarthria (59.5% vs. 40.3%, p < 0.001), history of atrial fibrillation (38.1% vs. 21.0%, p = 0.001), arterial hypertension (78.9% vs. 53.2%, p < 0.001), and less often with seizure (0.7% vs. 21.0%, p < 0.001). Conclusions The TM-score and certain patient characteristics can help paramedics and emergency physicians in the field to identify stroke mimic patients and select the most appropriate hospital destination.
Brain magnetic resonance imaging findings in postpartum headache
Authors: Shobeiri Elham , Torabinejad Behnam 
Published: October 2018

Objectives The objectives were to determine the frequency of abnormal magnetic resonance imaging findings in patients with postpartum headache and related factors. Methods A total of 102 patients with postpartum headache underwent brain magnetic resonance imaging study. The images were examined by a blinded radiologist. The related demographic, obstetric and headache-related factors were recorded. The multiple logistic regression model was used to determine the predictive factors. Results Abnormal magnetic resonance imaging findings were observed in 42 of 102 patients (41.2%, 95% confidence interval = 31.6 to 50.7%). The most common finding was sinusitis (10 of 42 patients, 23.8%, 95% confidence interval = 15.5 to 32%). Then, posterior reversible encephalopathy syndrome (six of 42 cases, 14.2%, 95% confidence interval = 7.4 to 20.9%), cerebral venous thrombosis (four of 42 cases, 9.5%, 95% confidence interval = 3.8 to 15.1%), and subarachnoid hemorrhage (four of 42 cases, 9.5%, 95% confidence interval = 3.8 to 15.1%) were most prevalent findings. Convulsions (odds ratio of 3.39) and initiation of headache earlier than 5 days postpartum (odds ratio of 0.29) were significant predictive factors. Conclusion Abnormal brain magnetic resonance imaging findings were seen in a considerable number of patients with postpartum headache. When headache starts in the first 5 days postpartum and accompanied by convulsions, there are likely to be abnormal magnetic resonance imaging findings.

Published: October 2018

Study Design: Longitudinal comparative cohort. Objectives: To determine if the duration of symptoms in patients with degenerative spondylolisthesis affects postoperative outcomes after 1- or 2-level decompression and fusion. Methods: Patients undergoing primary surgery for grade 1 degenerative spondylolisthesis at a single Quality Outcomes Database (QOD) participating site were identified. Demographic, surgical and patient-reported outcomes (PROs) data, including baseline and 12-month postoperative Oswestry Disability Index (ODI), back pain (BP, 0-10), leg pain (LP, 0-10), and EuroQOL-5D (EQ-5D) scores were collected. Individual medical records were reviewed for data on duration of symptoms prior to surgery. Patients were stratified into 3 cohorts—those with preoperative symptom duration of less than 1 year, 1 to 2 years, or greater than 2 years. Results: Complete data was available in 123 patients. Significant improvement in ODI, BP, and LP scores were observed in all groups. At 12-month follow-up improvement in ODI, BP, or LP was similar among the cohorts; with a trend toward significance with better improvement in LP scores in patients with a symptom duration of less than 1 year to those with symptom duration greater than 2 years ( P = .058). Conclusions: The duration of symptoms up to 2 years prior to surgery may not be a useful predictor of improvement of back pain or disability scores in patients with spondylolisthesis requiring decompression and fusion. Although there was a positive trend for improvement in leg pain for those with a shorter duration of symptoms, this did not reach statistical significance in our study.
Efficacy of the Adductor Canal Approach to Saphenous Nerve Block for Anterior Cruciate Ligament Reconstruction With Hamstring Autograft: A Randomized Controlled Trial
Authors: Kejriwal Ritwik , Cooper Jeremy , Legg Andrew , Stanley Jeremy , Rosenfeldt Michael P. , Walsh Stewart J. 
Published: October 2018

Background: For reconstruction of the anterior cruciate ligament (ACL) with hamstring autograft, perioperative analgesia can be achieved with multimodal analgesia and intra-articular local anesthesia infiltration with or without additional regional blocks. Saphenous nerve block (SNB) via the adductor canal is commonly used in our practice, but its benefit has not been well established in the literature. Purpose: To assess the efficacy of SNB in ACL reconstruction with hamstring autograft. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Consecutive patients undergoing arthroscopic ACL reconstruction with hamstring autograft were randomized into a control group (no SNB) and an intervention group (SNB). All patients received standardized anesthetic induction and maintenance agents with perioperative analgesia, per study protocol, with local anesthetic infiltration of the graft harvest site and intra-articular infiltration. Results: Sixty patients were randomized into the 2 groups (n = 30 each). There was no statistically significant difference in total opiate consumption between the groups (control, 34 mg; SNB, 31 mg; P = .40). There was no statistically significant difference in visual analog scale scores for pain at 0, 8, and 24 hours postsurgery, and no difference in overall satisfaction score. The control group had a significantly higher visual analog scale score at 4 hours postsurgery (3.0 vs 1.9, P = .04). Conclusion: SNB has a minimal effect on postsurgical care for ACL reconstruction with hamstring autograft in the presence of multimodal analgesia and local anesthetic infiltration.

AbstractVon Willebrand factor (VWF) is a key player in the regulation of hemostasis by promoting recruitment of platelets to sites of vascular injury. An array of 6 C domains forms the dimeric C-terminal VWF stem. Upon shear force activation, the stem adopts an open conformation allowing the adhesion of VWF to platelets and the vessel wall. To understand the underlying molecular mechanism and associated functional perturbations in disease-related variants, knowledge of high-resolution structures and dynamics of C domains is of paramount interest. Here, we present the solution structure of the VWF C4 domain, which binds to the platelet integrin and is therefore crucial for the VWF function. In the structure, we observed 5 intra- and inter-subdomain disulfide bridges, of which 1 is unique in the C4 domain. The structure further revealed an unusually hinged 2-subdomain arrangement. The hinge is confined to a very short segment around V2547 connecting the 2 subdomains. Together with 2 nearby inter-subdomain disulfide bridges, this hinge induces slow conformational changes and positional alternations of both subdomains with respect to each other. Furthermore, the structure demonstrates that a clinical gain-of-function VWF variant (Y2561) is more likely to have an effect on the arrangement of the C4 domain with neighboring domains rather than impairing platelet integrin binding.
A PET-positive rapidly growing mass of the abdominal wall after cesarean section with an unexpected diagnosis of vernix caseosa granuloma: a case report

Published: October 2018

Abstract
Background
Abdominal wall tumors are rare and include heterogeneous diseases. Among them, desmoid tumors are the most frequent and are often diagnosed in young women during or early after pregnancy; inflammatory response after trauma or microtrauma, such as after cesarean section, may favor their growth.

Results
A 37-year-old woman presented with a progressive mass in the abdominal wall after a cesarean section. Positron emission tomography imaging confirmed a positive mass with a high maximum standardized uptake value; a biopsy suggested a myofibroblastic tumor. With continued tumor growth and worsening symptoms, the mass resembled a desmoid tumor; therefore, we proceed with its resection. The final diagnosis was foreign body granuloma as a reaction to the spillage of meconium and keratinous material in the amniotic fluid during cesarean section.

Conclusions
The present case provides information on an abdominal wall foreign body granuloma arisen from meconium and vernix caseosa after cesarean section, which presented an atypical clinical picture, mimicking a desmoid, thus requiring a careful diagnostic and treatment approach.
Combination therapy to checkmate Glioblastoma: clinical challenges and advances
Authors: Ghosh Debarati , Nandi Saikat , Bhattacharjee Sonali 
Published: October 2018

AbstractCombination therapy is increasingly becoming the cornerstone of current day antitumor therapy. Glioblastoma multiforme is an aggressive brain tumor with a dismal median survival post diagnosis and a high rate of disease recurrence. The poor prognosis can be attributed to unique treatment limitations, which include the infiltrative nature of tumor cells, failure of anti‐glioma drugs to cross the blood–brain barrier, tumor heterogeneity and the highly metastatic and angiogenic nature of the tumor making cells resistant to chemotherapy. Combination therapy approach is being developed against glioblastoma with new innovative combination drug regimens being tested in preclinical and clinical trials. In this review, we discuss the pathophysiology of glioblastoma, diagnostic markers, therapeutic targeting strategies, current treatment limitations, novel combination therapies in the context of current treatment options and the ongoing clinical trials for glioblastoma therapy.
