Low serum 25-hydroxyvitamin D levels in migraine are not related to headache frequency: A case-control study in patients with high-frequency/chronic migraine.

Background: Serum 25-hydroxyvitamin D (25[OH]D) concentrations have been shown to be low in patients with migraine, but results are controversial regarding the current role of vitamin D in migraine severity. Using a case-control design, we aimed to evaluate serum 25(OH)D levels in a group of females with high-frequency episodic migraine/chronic migraine (HF/CM) and analyze its association with headache frequency and serum calcitonin gene-related peptide (CGRP) levels.

Methods: Serum 25(OH)D levels were measured in 97 females with HF/CM (age 48.

M2 Macrophages are Major Mediators of Germline Risk of Endometriosis and Explain Pleiotropy with Comorbid Traits.

Endometriosis is a common gynecologic condition that causes chronic life-altering symptoms including pain, infertility, and elevated cancer risk. There is an urgent need for new non-hormonal targeted therapeutics to treat endometriosis, but until very recently, the cellular and molecular signatures of endometriotic lesions were undefined, severely hindering the development of clinical advances. Integrating inherited risk data from analyses of >450,000 individuals with ∼350,000 single cell transcriptomes from 21 patients, we uncover M2-macrophages as candidate drivers of disease susceptibility, and nominate IL1 signaling as a central hub impacted by germline genetic variation associated with endometriosis.

Amyloid Goiter: A Peruvian Case Series.

: Amyloid goiter (AG) is a rare cause of thyroid swelling, characterized by deposits of amyloid protein in the thyroid tissue. It can be associated with primary or secondary amyloidosis. Its prevalence in multinodular goiter cases is 0.

Protocol for building and using a maximum power point output tracker for perovskite solar cells.

We recently developed a galvanostatic maximum power point output (MPPT) algorithm for high-hysteresis perovskite solar cells (PSCs), enabling continuous and precise power tracking. Here, we present a protocol for assembling the tracker, implementing the algorithm on a microcontroller, and conducting JV scans and stabilized output power (SOP) or traditional perturb and observe (P&O) tracking for small-area photovoltaic cells. We also describe steps for collecting, storing, and plotting data and explain the device's operational modes and functions.

Evaluation of an expanded antibiotic resistance gene panel on prediction of antimicrobial susceptibility results for Gram-negative bacteria in blood cultures.

Unlabelled: The QIAstat-Dx BCID Panels (RUO) ("QIAstat," QIAGEN, Hilden, Germany) for identification of 13 Gram-negative bacteria and 18 antimicrobial resistance (AMR) gene groups was evaluated. The study was conducted in two phases; in phase 1, analytical performance was evaluated against 154 challenge isolates against whole genome sequencing data. In this phase, sensitivity and specificity of organism identification calls were 153/154 (99.
