The great interest in molecular epidemiology of human papilloma virus (HPV) in cervical cancer led us to perform a thorough evaluation of 2 polymerase chain reaction (PCR)-based methods for the detection of HPV in archival formalin-fixed paraffin-embedded (FFPE) samples. Thus, the aim of this study was to compare HPV detection in FFPE samples that have histopathologic diagnosis of invasive cervical cancer using SPF10 broad-spectrum primers PCR followed by DNA enzyme immunoassay and LiPA25 (version 1: Labo Biomedical products, Rijswijk, The Netherlands version 1) and the Papillomavirus Clinical Arrays technique (Genómica, Tres Cantos, Madrid, Spain). In this study, 235 biopsies with histopathologic diagnosis of invasive cervical cancer were analyzed for the detection and genotyping of HPV by LiPA25 SPF10-PCR System (version 1) and Papillomavirus Clinical Arrays technique. The detection of HPV DNA with Genómica technique was 75.1%, and 91.9% with LiPA25 SPF10-PCR. The Genómica technique detected a higher percentage of multiple infections (35%) than LiPA25 (8.9%), with a very low agreement for the detection of multiple infections between them (P>0.05). Our study highlights an important difference between 2 PCR-based methods for detection and genotyping of HPV. LiPA25 SPF10-PCR technology may be more adequate than Genómica for the detection of HPV DNA when using FFPE tissue.

The pursuit of cutting-edge diagnostic systems capable of detecting biomarkers with exceptional sensitivity and precision is crucial for the timely and accurate monitoring of inflammatory responses. In this study, we introduce a dual gold nanoparticle-enhanced metasurface plasmon resonance (Bi-MSPR) biosensor for the ultrasensitive detection of C-reactive protein (CRP). The Bi-MSPR sensor is constructed upon a nanocup array chip with gradient-free electron density, where an innovative metasurface structure is built using a PEI-immobilized dual-gold nanoparticle amplification system.

To identify patients with infantile hemangioma (IH) in need of early-stage treatment in this multicenter, prospective, observational study, we investigated the potential of plasma cytokines as a clinically useful marker. Plasma samples were collected at three time points from 41 patients with infantile hemangioma: baseline (days 14-60 after delivery), visit 1 (days 61-150, the proliferative phase), and visit 2 (days 151-395, the involuting phase). With a twofold or more increase in tumor volume during the baseline-visit 1 period regarded as progression, progression was seen in 15 cases (36.

In recent years, regulatory authorities have signaled a willingness to consider real-world evidence (RWE) data to support applications for new claims and indications for pharmaceuticals. Historically, RWE studies have been the domain of prescription drugs, driven by the fact that clinical data on patients are routinely captured in medical records, claims databases, registries, etc. However, RWE reports of nonprescription drugs and supplements are relatively sparse due to methodological gaps in this area.

Background: Cerebral venous thrombosis (CVT) is a rare but potentially life-threatening condition characterized by the formation of a blood clot in the dural venous sinuses or cerebral veins. CVT presents a diverse array of clinical symptoms, making its diagnosis challenging. Understanding regional variations and specific risk factors associated with CVT is crucial, especially in low-resource settings like Somalia, where epidemiological data is limited and healthcare resources are scarce.

Background: This study was conducted to evaluate screening procedures for anal high-grade squamous intraepithelial lesions (HSILs) with anal liquid-based cytology (aLBC) and biomarkers to identify candidates for high-resolution anoscopy (HRA).
Methods: This cross-sectional study included men who have sex with men with HIV. Participants underwent HRA, aLBC, and biomarker testing.
