In recent years, several case reports and outbreaks reported occurrence of non-tuberculous mycobacteria (NTM) infections within 6 months after receiving a tattoo in healthy individuals. NTM species (e.g., Chelonae, Fortuitum, Hemophillum, and Abscessus) are widespread in the environment and it is often suspected that contamination may occur through unsterile instrumentation or unsterile water used for diluting tattoo ink to dilute color. In reported cases, lesions were mainly restricted to a single color 'gray' part of the tattoo. Mycobacterium Chelonae was the most common cause of tattoo associated NTM infections. Less than 50% of the case reports tested tattoo ink for acid fast bacilli stains and cultures. Subjects required treatment with either clarithromycin alone or in combination with quinolones for 6 to 9 months. An increase in NTM skin infections in healthy individuals after tattooing indicates the need for sterile standards during tattooing and improved local and regional regulatory oversight.

Background: The pressure gradient between the ventricles and the subarachnoid space (transmantle pressure) is crucial for understanding CSF circulation and the pathogenesis of certain neurodegenerative diseases. This pressure can be approximated by the pressure difference across the aqueduct (ΔP). Currently, no dedicated platform exists for quantifying ΔP, and no research has been conducted on the impact of breathing on ΔP.

Background: Accurate classification of host phenotypes from microbiome data is crucial for advancing microbiome-based therapies, with machine learning offering effective solutions. However, the complexity of the gut microbiome, data sparsity, compositionality, and population-specificity present significant challenges. Microbiome data transformations can alleviate some of the aforementioned challenges, but their usage in machine learning tasks has largely been unexplored.

Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.
Methods: This is a retrospective interventional case report.

Background: Family income to poverty ratio (PIR) may have independent effects on diet and lifestyle factors and the development of prediabetes and diabetes, as well as on mortality. It is unclear how the protective effect of a healthy lifestyle against death differs between individuals with different glucose metabolic profiles and whether PIR mediates this effect. This study aimed to explore whether healthy lifestyle and family PIR reduced the risk of all-cause mortality in participants with different metabolic status and the mediating role of PIR.

Heart rate variability (HRV) is a key indicator of cardiac autonomic function, making reliable assessment crucial. To examine the test-retest stability of resting HRV in healthy individuals, fifty participants attended two lab sessions within a week, at the same time of day. After a 5-minute acclimatization period, electrocardiogram and respiration were recorded at rest.
