Background: This study investigated reported differences in age at onset and progression of presbyopia between black and white patients.
Methods: The records of 692 primary care patients (242 black and 450 white), ages 35 to 55 years, who received eye examinations at the University of Alabama at Birmingham School of Optometry (December 1, 1992 and May 31, 1993), were reviewed retrospectively. Regression models were used to compare age at onset and progression of presbyopia of study subjects with respect to race. Also, the effect of socioeconomic status (SES) was assessed for a subset of 373 subjects.
Results: No significant differences in the age at onset or progression of presbyopia were detected between black and white patients (p > 0.05). Similarly, there were no significant differences in age at onset and progression of presbyopia with respect to socioeconomic status.
Conclusions: Contrary to previous studies, the onset and progression of presbyopia of black and white patients in this study population did not differ significantly. This result suggests other factors may play a role in previously reported variation of presbyopia in black and white patients. Similarly, variations in income status did not significantly impact the onset and progression of presbyopia. Further study is needed to corroborate or refute these findings.

Using Fourier Transform Infrared spectroscopy (FTIR), it is possible to show chemical composition of materials and / or profile chemical changes occurring in tissues, cells, and body fluids during onset and progression of diseases. For diagnostic application, the use of blood would be the most appropriate in biospectroscopy studies since, (i) it is easily accessible and, (ii) enables frequent analyses of biochemical changes occurring in pathological states. At present, different studies have investigated potential of serum, plasma and sputum being alternative biofluids for lung cancer detection using FTIR.

Moyamoya disease (MMD) is a progressive cerebrovascular disorder that increases the risk of intracranial ischemia and hemorrhage. Timely diagnosis and intervention can significantly reduce the risk of new-onset stroke in patients with MMD. However, the current diagnostic methods are invasive and expensive, and non-invasive diagnosis using biomarkers of MMD is rarely reported.

Kawasaki disease (KD) is an inflammatory condition more common in children but rare in adults, where diagnosis can be challenging due to nonspecific symptoms. Early recognition is essential to prevent severe complications. We present the case of a 26-year-old male with adult-onset KD who initially presented with vague symptoms, resulting in diagnostic delays.

Ischemia-reperfusion injuries (IRI) across various organs and tissues, along with sepsis, significantly contribute to the progression of critical illnesses. These conditions disrupt the balance of inflammatory mediators and signaling pathways, resulting in impaired physiological functions in human tissues and organs. Ferroptosis, a distinct form of programmed cell death, plays a pivotal role in regulating tissue damage and modulating inflammatory responses, thereby influencing the onset and progression of severe illnesses.

Cardiovascular diseases (CVD) are the foremost cause of mortality worldwide, with recent advances in immunology underscoring the critical roles of immune cells in their onset and progression. MicroRNAs (miRNAs), particularly those derived from the immune system, have emerged as vital regulators of cellular functions within the cardiovascular landscape. This review focuses on "immuno-miRs," a class of miRNAs that are highly expressed in immune cells, including T cells, B cells, NK cells, neutrophils, and monocytes/macrophages, and their significant role in controlling immune signaling pathways.
