As diagnostic biosensors for analyzing fluids from the human body, the development of inorganic NPs is of increasing concern. For one, nanoceramic phosphors have been studied to meet the increasing requirements for biological, imaging, and diagnostic applications. In this study, YONPs co-doped with trivalent rare earth…

BACKGROUND: Businesses and organizations involved in growing, distributing, and supplying food may face severe disruptions from natural and human-generated hazards, ranging from extreme weather to political unrest. Baltimore, Maryland, is developing policies to improve local food system organizations' ability to prepar…

Streptococcus pneumoniae is an important human pathogen causing various diseases. In this study, S. pneumoniae from invasive (IPD) and noninvasive pneumococcal disease (NIPD) were studied by serotype and multilocus sequence typing (MLST) for population structure characteristics. A total of 169 clinical S. pneumoniae, c…

Multiple-use dental bib clips are considered to present relatively low risks for transmitting infections and, thus, are thought to only require disinfection between patient visits. This study was designed to: 1) determine the presence and composition of bacterial contaminants on reusable rubber-faced metal bib clips af…

OBJECTIVES: Recent studies show that chronic exposure to racial discrimination increases the occurrence of subjective cognitive decline (SCD) among Black Americans. Little research, however, has examined potential for protective factors, such as perceived partner support, to buffer these effects. METHODS: This study u…

BACKGROUND/OBJECTIVES: Most studies about Papillon-Lefèvre syndrome (PLS) are limited to case reports and patients of the same nationality. This study aimed to determine the self-reported prevalence of signs, symptoms and treatment effectiveness in PLS patients from five Latin American countries. METHODS: An onli…

This study's primary aim was to assess whether end-expiratory lung ultrasound severity score (expLUSsc) at Day 3 of life, the second week of life, and before weaning off nasal continuous positive airway pressure (nCPAP) can predict the weaning readiness off nCPAP trial in preterm infants. The secondary aim was to…

As the obesity epidemic continues, there is a great need for safe and effective weight loss aids. A superabsorbent hydrogel device administered as a capsule demonstrates potential for weight loss, but its mechanism of action remains unclear. The present study's goal was to determine the mechanisms of action of the hydr…

Paediatric meningiomas are extremely rare. These tumours constitute only 2 to 3% of all childhood brain tumours. Despite similarities in histological features between PMs and their adult counterparts, there are important distinctions between them. In this case series, the authors describe their experience in paediatric…

BACKGROUND: Secondary fusion of initially patent cranial sutures after primary correction of nonsyndromic craniosynostosis is rarely reported. This study's aim is to report the incidence and analyze whether there are variables that may predispose to such fusion. METHODS: A single-institution, retrospective, case-contr…

PURPOSE: The aim of the study was to evaluate the thickness of each corneal sublayer in patients with pseudoexfoliation syndrome (PXS). METHODS: The study's sample consisted of the 74 eyes of 74 patients with PXS (group 1) and the 80 eyes of 80 individuals without PXS (group 2). Each participant was performed anterior…

BACKGROUND AND PURPOSE: Musculoskeletal disorders (MSDs) are alarmingly high among migrant workers in Malaysia. MSDs are the most prevalent occupational-related conditions in most parts of the world affecting function, productivity and overall health-related quality of life. Therefore, this study aims to determine the…

PURPOSE: We recently reported the results from a multi-institutional retrospective outcome study involving 814 patients with renal cell carcinomas (RCCs) who had undergone radical surgery and whose diagnoses were confirmed via a central pathological review. This study aimed to clarify the impact of tumor size on surviv…

OBJECTIVE: Prior studies have indicated that exposure to potentially traumatic events (PTEs) may increase the risk of poor mental and physical health outcomes. This study's main goal is to examine the association between PTE exposures and having any past year mental disorder, substance use disorder (SUD), or functional…

BACKGROUND: Recent studies have shown that Vitamin D deficiency is very common globally. Vitamin D deficiency is associated with lipid metabolism. A relationship between vitamin D levels and waist circumference (WC) has been observed. The purpose of this study is to evaluate the relationship between vitamin D status an…

OBJECTIVE: To determine if persons with chronic stroke and decreased hip and knee flexion during swing can walk with improved swing-phase kinematics when the task demands constrained gait to the sagittal plane. DESIGN: A one-day, within-subject design comparing gait kinematics under two conditions: Unconstrained tread…

OBJECTIVE: the purpose of this study was to evaluate the prevalence of autoimmune thyroiditis and thyroid dysfunction in healthy individuals with no previously known thyroid disease, in an urban area of Mexico City. SUBJECTS AND METHODS: the study was conducted on volunteers with no known thyroid disease. We recruited…

OBJECTIVE: The objective of this study was to investigate whether total knee arthroplasty (TKA) impairs the ability to perform an emergency stop. DESIGN: An automatic transmission brake simulator was developed to evaluate total brake response time. A prospective repeated-measures design was used. Forty patients (20 le…

BACKGROUND: This study was devised to examine the effect of a novel biomechanical therapy for patients suffering from anterior knee pain (AKP). METHODS: A retrospective analysis of 48 patients suffering from AKP was performed. Patients underwent a gait evaluation, using an electronic walkway mat, and completed the SF-…

PURPOSE: This study's purpose was to compare the frequency of enamel defects (ED) in the complete primary dentition (CDD) of term children (TC) and preterm children (PTC) and to analyze neonatal factors associated with ED in PTC. METHODS: The study group was formed by 45 PTC, cared for at the Follow-up Clinic for Pret…
