Epilepsy and Anti-Seizure Medications: Secret Agents for Endocrine Disruption.

There is a reciprocal relationship between epilepsy and reproductive endocrine disorders. Seizures and anti-seizure medications (ASMs) can contribute to reproductive and endocrine dysfunction and reproductive dysfunction may exacerbate seizures. Epilepsy via neuroendocrine mechanisms affects the hypothalamic-pituitary-ovarian (HPO) axis, disrupting the regulation of gonadotropin secretion, and resulting in dystrophic effects on the ovaries and early menopause.

Efficacy and Safety of XEN1101, a Novel Potassium Channel Opener, in Adults With Focal Epilepsy: A Phase 2b Randomized Clinical Trial.

Importance: Many patients with focal epilepsy experience seizures despite treatment with currently available antiseizure medications (ASMs) and may benefit from novel therapeutics.

Objective: To evaluate the efficacy and safety of XEN1101, a novel small-molecule selective Kv7.2/Kv7.

Empiric dosing strategies to predict lamotrigine concentrations during pregnancy.

Introduction: Maintaining seizure control with lamotrigine is complicated by altered pharmacokinetics and existence of subpopulations in whom clearance increases or remains constant during pregnancy.

Objective: Our objective was to characterize the potential for particular dosing scenarios to lead to increased seizure risk or toxicity.

Methods: Lamotrigine pharmacokinetic parameters obtained from our previous study were applied to a one-compartment model structure with subpopulations (75:25%) exhibiting different clearance changes.

Catamenial epilepsy occurrence and patterns in a mixed population of women with epilepsy.

We evaluated the occurrence and distribution of patterns of catamenial epilepsy in a heterogenous cohort of women with epilepsy on no hormonal therapies, enrolled in a prospective, observational study. The primary aim of the study was pregnancy rate in women with epilepsy with no prior reproductive problems. In this analysis, we included women who recorded one or more menstrual cycles with one or more seizures.

Detection of pneumococcus during hospitalization for SARS-CoV-2.

Background: Infections with respiratory viruses [e.g. influenza and respiratory syncytial virus (RSV)] can increase the risk of severe pneumococcal infections.

Histopathology reporting of temporal artery biopsy specimens for giant cell arteritis: results of a modified Delphi study.

Unlabelled: The temporal artery biopsy (TAB) is regarded as the gold-standard test in the diagnosis of giant cell arteritis (GCA). There is a lack of agreement among experienced pathologists regarding the diagnostic features and classification of inflammation observed in TAB sections in the diagnosis of GCA.

Aims: The aim of this research study was to establish consensus on the key parameters which should be included in a standardised reporting proforma for TAB specimens.

Considerations for determining the efficacy of new antiseizure medications in children age 1 month to younger than 2 years.

Objectives: Drug treatment for children with epilepsy should, ideally, be governed by evidence from adequate and well-controlled clinical studies. However, these studies are difficult to conduct, and so direct evidence supporting the informed use of specific drugs is often lacking. The Research Roundtable for Epilepsy (RRE) met in 2020 to align on an approach to therapy development for focal seizures in children age 1 month <2 years of age.

Role of Transbronchial Lung Cryobiopsy in the Diagnosis of Interstitial Lung Disease: A Meta-analysis of 68 Studies and 6300 Patients.

Background: Diagnosis of interstitial lung disease (ILD) is based on multidisciplinary team discussion (MDD) with the incorporation of clinical, radiographical, and histopathologic information if available. We aim to evaluate the diagnostic yield and safety outcomes of transbronchial lung cryobiopsy (TBLC) in the diagnosis of ILD.

Methods: We conducted a meta-analysis by comprehensive literature search to include all studies that evaluated the diagnostic yields and/or adverse events with TBLC in patients with ILD.

Global health education in high-income countries: confronting coloniality and power asymmetry.

Contemporary global health education is overwhelmingly skewed towards high-income countries (HICs). HIC-based global health curricula largely ignore colonial origins of global health to the detriment of all stakeholders, including trainees and affected community members of low- and middle-income countries. Using the Consortium of Universities for Global Health's , we analyse the current structure and content of global health curricula in HICs.

Evidence for SARS-CoV-2 Spike Protein in the Urine of COVID-19 Patients.

Background: SARS-CoV-2 infection has, as of April 2021, affected >133 million people worldwide, causing >2.5 million deaths. Because the large majority of individuals infected with SARS-CoV-2 are asymptomatic, major concerns have been raised about possible long-term consequences of the infection.

Clinical characteristics and treatment experience of individuals with SCN8A developmental and epileptic encephalopathy (SCN8A-DEE): Findings from an online caregiver survey.

Purpose: SCN8A developmental epileptic encephalopathy (SCN8A-DEE) is a rare and severe genetic epilepsy syndrome characterized by early-onset developmental delay, cognitive impairment, and intractable seizures. SCN8A gene variants are associated with a broad phenotypic spectrum and variable disease severity. A caregiver survey, solicited by the advocacy group The Cute Syndrome Foundation (TCSF), was conducted to gather information on the demographics/disease presentation, seizure history, and treatment of patients with SCN8A-related epilepsies.

Building the foundation of health-related knowledge via near-peer education for children with sickle cell disease.

Health education for children with chronic illnesses (i.e., sickle cell disease [SCD]) has focused on educating adult caregivers with minimal consideration to educating the pediatric patients.

Antiseizure Medication Withdrawal in Seizure-Free Patients: Practice Advisory Update Summary: Report of the AAN Guideline Subcommittee.

Objective: To update a 1996 American Academy of Neurology practice parameter.

Methods: The authors systematically reviewed literature published from January 1991 to March 2020.

Results: The long-term (24-60 months) risk of seizure recurrence is possibly higher among adults who have been seizure-free for 2 years and taper antiseizure medications (ASMs) vs those who do not taper ASMs (15% vs 7% per the 1 Class I article addressing this issue).

Isoflurane as an Accurate Negative Mode Calibrant for Ion Mobility Spectrometry.

The search for suitable ion mobility spectrometry (IMS) calibrant compounds is ongoing and necessitates the use of highly accurate reduced ion mobility () values across a range of instrumental conditions. Such values will be used in calibrating devices to shift the ion mobility scales and alarm windows for chemicals of interest to their proper locations based on the instrumental conditions present during calibration and sampling. Many positive ion mode calibrants have been investigated, whereas investigations for a negative ion detection mode calibrant have been more limited.

A 60-Year-Old Man With Dyspnea, Proximal Muscle Weakness, and Pulmonary Arterial Hypertension.

A 60-year-old man with no significant medical history presented to the pulmonology clinic with 2 years of progressive weakness and shortness of breath. Showering and other activities of daily living caused him significant fatigue and dyspnea. He had a 20-pack-year smoking history, but no significant history of alcohol or illicit drug use.

The community-wide effectiveness of municipal larval control programs for West Nile virus risk reduction in Connecticut, USA.

Background: Mosquito larval control through the use of insecticides is the most common strategy for suppressing West Nile virus (WNV) vector populations in Connecticut (CT), USA. To evaluate the ability of larval control to reduce entomological risk metrics associated with WNV, we performed WNV surveillance and assessments of municipal larvicide application programs in Milford and Stratford, CT in 2019 and 2020. Each town treated catch basins and nonbasin habitats (Milford only) with biopesticide products during both WNV transmission seasons.

Stability of SARS-CoV-2 RNA in Nonsupplemented Saliva.

The expense of saliva collection devices designed to stabilize severe acute respiratory syndrome coronavirus 2 RNA is prohibitive to mass testing. However, virus RNA in nonsupplemented saliva is stable for extended periods and at elevated temperatures. Simple plastic tubes for saliva collection will make large-scale testing and continued surveillance easier.

Capturing seizures in clinical trials of antiseizure medications for -DEE.

Literature review of patients with developmental and epileptic encephalopathy (-DEE) reveals, based on 16 reports including 139 patients, a clinical phenotype that includes age- and disease-specific stereotyped seizures. The typical seizure type of -DEE, focal tonic, starts within 0-5 days of life and is readily captured by video-electroencephalography VEEG for clinical and genetic diagnosis. After initial identification, -DEE seizures are clinically apparent and can be clearly identified without the use of EEG or VEEG.

SalivaDirect: A simplified and flexible platform to enhance SARS-CoV-2 testing capacity.

Background: Scaling SARS-CoV-2 testing to meet demands of safe reopenings continues to be plagued by assay costs and supply chain shortages. In response, we developed SalivaDirect, which received Emergency Use Authorization (EUA) from the U.S.

Simply saliva: stability of SARS-CoV-2 detection negates the need for expensive collection devices.

Most currently approved strategies for the collection of saliva for COVID-19 diagnostics require specialized tubes containing buffers promoted for the stabilization of SARS-CoV-2 RNA and virus inactivation. Yet many of these are expensive, in limited supply, and not necessarily validated specifically for viral RNA. While saliva is a promising sample type as it can be reliably self-collected for the sensitive detection of SARS-CoV-2, the expense and availability of these collection tubes are prohibitive to mass testing efforts.
