As the news of approval of COVID-19 vaccination emerge, neurologists across the globe ponder upon whether to use immunotherapies in patients with Multiple Sclerosis (MS). This paper highlights the mechanism of various disease modifying therapies (DMTs) as well as the recently approved Pfizer and Moderna vaccines for COVID-19 as well as guidelines as introduced by National Multiple Sclerosis Society. As their mechanisms counteract each other at the molecular level, we believe further evidence and data might lay the foundation to formulate much needed recommendations for the usage of these medications while vaccinating MS patients on DMTs.

We measured the proportion of Lewy body pathology (LB), hippocampal sclerosis (HS), and cerebral amyloid angiopathy (CAA) among community-dwelling people with and without dementia.

We searched for community-based cohorts with postmortem brain autopsy until 1 January 2020. We calculated the summary risk difference and 95% confidence interval (95% CI) using a random-effects model in R.

We found 12 articles, comprising 2197 demented and 2104 non-demented participants. LB, HS, CAA were prevalent lesions among community-dwelling elderly (15%, 10%, and 24%, respectively). These significantly increased the risk of dementia (LB risk difference 38%, 95% CI 20-56%, HS 34%, 24-44%, CAA 19%, 3-34%). 20% of cases with neocortical LB, 17% with bilateral HS, and 42% with moderate/severe CAA pathology remained non-demented by death.

LB or HS or CAA are common neuropathologies among community-dwelling elderly. Although these lesions independently are associated with dementia, many remain non-demented, by death.

This study assessed the clinical characteristics and predictors of vascular events occurring within 5 years after ICH. We included consecutive patients diagnosed with first-ever ICH between June 2013 and December 2014. Based on follow-up data (collected until December 2019), we used multivariable logistic regression to examine the clinical characteristics and long-term predictors of vascular events (including recurrent ICH, ischemic stroke, and acute coronary syndrome) in patients who survived more than 30 days after ICH. Across the 307 patients in our analysis, the 5-year mortality rate was 28.01%. Within 5 years after ICH, major vascular events were observed in 62 patients (17.82%, 95% CI 13.78-21.82%). We observed high incidence of recurrent ICH (8.91%) and ischemic stroke (10.06%), but low incidence of acute coronary syndrome (1.15%). Most cases of recurrent ICH (80.65%) occurred within 3 years after ICH. Age ≥56 years and history of ischemic stroke or transient ischemic attack (TIA) were identified as predictors of cardiovascular and cerebrovascular events. ICH survivors are at high risk of both cardiovascular and cerebrovascular events, especially older patients (≥56 years) and those who experienced ischemic stroke or TIA prior to their first ICH. Recurrent ICH is more likely to occur within the first three years after first ICH than at later times. Clinicians should monitor patients closely for adverse events, particularly during the first three years after initial ICH.Vagus nerve stimulation (VNS) and anterior thalamic deep brain stimulation (ANT-DBS) have both been used for treatments of drug-resistant epilepsy (DRE). However, there is no comparative study on the effectiveness of two methods from one single center. 17 patients with DRE who underwent VNS therapy and 18 patients who underwent DBS were enrolled. A retrospective study was performed starting from baseline before operation extending to 12 months after operation. The seizure types, duration of epilepsy, age at implantation, failed numbers of antiepileptic drugs (AEDs) before operation, history of craniotomy, stimulation parameters and response rate were described. The analysis of liner regression on the age of onset, duration of epilepsy, numbers of AEDs, and the seizure reduction at 12 months after operation was applied. The mean seizure reduction in patients with DBS at 3, 6, 9 and 12 months after the operation was 57.22%, 61.61%, 63.94% and 65.28%, and that in cases with VNS was 36.06%, 39.94%, 45.24% and 48.35%, respectively. At 1 year after the operation, the patients with older operation age, focal seizures and older age of onset responded better to VNS; and those older operation age, focal generalized seizures, history of craniotomy and longer duration of disease responded better to DBS. The efficiency of ANT-DBS was higher than that of VNS at each follow up time point. Patients can choose the appropriate treatment according to the individual clinical characteristics.

Any preoperative diagnostic assessment that can predict the success of the operation in acromegaly will provide a positive impact on overall remission rates. The aim of this study is to reveal whether the signal intensity in T2-weighted Magnetic Resonance Imaging can predict postoperative results in acromegaly patients with macroadenoma.

We analyzed our surgical results in regard to T2-weighted images in newly diagnosed consecutive 124 patients with acromegaly, operated between 2014 and 2019. The T2-intensity of the pure somatotroph macroadenomas was correlated with the clinical, radiological, surgical and histopathological characteristics of the acromegaly patients.

We found a predominance of T2-hyperintensity in our series (45%) and the T2-hypointense pure somatotroph adenomas were detected in only 34% of our patients. Total resection was performed in 72% of newly diagnosed acromegaly patients in this series. Accordingly, total resection was achieved in 69% of the T2-hyperintense group, 77% of the T2-ity of post-surgical remission in patients with newly diagnosed acromegaly. Further support fort this idea comes from recent guidelines for acromegaly management in which the potential utility of using T2 intensity to optimize patient management has been emphasized.Pineal germinoma is rare with high cure rates following craniospinal radiotherapy. Efforts to reduce the radiotherapy dose and field via combination with chemotherapy suggest comparable disease control and reduced neurocognitive impairments, while the efficacy of immunotherapy in pineal germinoma remains undetermined. This report aimed to review clinical outcomes in patients treated for pineal germinoma in Queensland, Australia, and assess for Programmed Death-Ligand1 (PD-L1) expression. Patients who commenced radiation and/or chemotherapy for pineal germinoma from 2005 to 2017 were retrospectively identified using Queensland Oncology Online database. Demographic, diagnostic, treatment, and outcome data was obtained from electronic medical records. PD-L1 immuno-histochemistry was performed on available specimens. Eighteen patients with long-term follow-up data were identified. Median age at diagnosis was 16.8 years (range 9-46 years). Diagnosis was made histologically in fifteen patients, and radiologically in three. All patients underwent radiotherapy (median 36 Gy (range 21-54 Gy)) with lower median dose delivered with whole ventricle irradiation (12/18patients) than craniospinal irradiation (5/18patients). Cyclopamine Sixteen patients received chemotherapy preceding radiotherapy. All patients are alive at median 7.25 years from primary treatment completion (range 2.03-13.1 years). Relapse occurred in three patients (16.67%) following treatment response, all of whom achieved remission following high-dose chemotherapy with stem-cell support and craniospinal radiotherapy. Post-treatment functional outcomes were similarly excellent. PD-L1 expression was low (1-49% cells) or negative in 87% of tumours tested but results were confounded by specimen quality and availability. Reduced-dose radiotherapy with chemotherapy does not compromise outcome and is standard of care at this institution. Immunotherapy is unlikely to become standard treatment in the near future.

To determine the rate of high-grade cervical intraepithelial lesion and cancer (HSIL+) diagnosis as a result of colposcopic histopathology in patients aged ≥50 years and to investigate the role of cytology, Human Papillomavirus (HPV) test positivity and HPV genotyping in predicting HSIL+.

The study included 1102 patients aged ≥50 as study group and 2723 patients aged <50 as control group who were admitted to our colposcopy unit between January 1, 2015 and December 31, 2019 and underwent colposcopy for the first time. The patients with HSIL+ were compared as Cytology group and HPV group in the study group. To evaluate the impact of genotyping HPV positive group was compared in terms of HSIL+ results in subgroups with HPV16/18 and HPV other types positivity. Patients diagnosed with cancer in the same period were compared in terms of age, stage and histology as screening cancer group and symptomatic cancer groups.

The rate of cervical cancer in the study group was 2.2% and 1.2 % in the control group. Inould be re-evaluated.An adolescent female classified as unstable with a spontaneous abdominal hemorrhage was transferred to a level 1 pediatric trauma tertiary emergency department. Pertinent medical history included von Willebrand disease type 3, menorrhagia, and obesity. Preparation before patient arrival included mobilization of multidisciplinary medical team experts in hematology, pharmacy, blood bank, radiology, and nursing who provided lifesaving interventions. The administration of factor products, blood products, interventional radiology, emergent hepatic angiography, and embolization coordination resulted in a successful outcome. After an 18-day intensive hospital course, the patient returned home close to her baseline health status.

National debate persists surrounding the expanded use of nurse practitioners in the emergency department. Current understanding of the alignment of nurse practitioner educational preparation and practice parameters in United States emergency departments is inchoate. The objective of this review was to seek evidence to support that nurse practitioner education and training align with current practices in the emergency department.

A Preferred Reporting Items for Systematic Reviews and Meta-Analyses guided systematic review of the existing literature was conducted of 4 relevant databases. Level of evidence and quality assignments were made for each article using Grading of Recommendations, Assessment, Development, and Evaluation or Confidence in Evidence from Reviews of Qualitative Research as appropriate.

Nurse practitioners are increasingly staffing emergency departments, providing care to both patients classified as high-acuity and low-acuity. Reports of nurse practitioner scope of practice vary widely.ic preparation for specialty practice in the emergency department and to specifically examine the alignment of educational preparation with scope of practice and impact on clinical outcomes of patients seen in the emergency department.
