New papulovesicular rash in the course of COVID-19 signaling viral reactivation.
Cutaneous manifestations are considered an infrequent presentation of coronavirus disease 2019 (COVID-19) and are mostly described in outpatient settings. Its onset during the course of the severe COVID-19 disease has been poorly described in severe cases. ⋯ We described the occurrence of a vesiculopapular eruption in three laboratory-confirmed COVID-19 patients associated with severe lung injury in whom the skin findings preceded viral reactivation and recrudescence of hypoxemia. The potential mechanisms for COVID-19-related cutaneous manifestations include immune hypersensitivity, cytokine-release syndrome, deposition of microthrombi, and vasculitis.

Anxiety in candidates for radical prostatectomy in a university hospital.
Metabolic changes caused by anxiety can interfere in both the surgery itself and the recovery process. One way to reassure the patient is to clarify how the procedure will be performed and discuss the possible complications. This study aimed to investigate the anxiety level of candidates for radical prostatectomy at a university hospital. ⋯ The present study demonstrates that the explanations given by the multidisciplinary health team are not achieving their maximum potential in terms of lowering patient anxiety.

Telomere length: biological marker of cellular vitality, aging, and health-disease process.
The aging process occurs due to the decline of vital physiological functions and adaptability of the body, being influenced by genetics and lifestyle. With advances in genetics, biological aging can be calculated by telomere length. Telomeres are regions at the ends of chromosomes that play a role in the maintenance and integrity of DNA. ⋯ Several studies show that shorter telomeres are associated with acute and chronic diseases, stress, addictions, and intoxications. Even in the current COVID-19 pandemic, telomere shortening is proposed as a marker of severity in individuals infected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). On the other hand, healthy lifestyle habits increase telomere length and balance of various cellular functions, preventing diseases.

Salivary glands of fetuses are adversely affected by artificial food colorings in rats.
Artificial food colorings, as types of food additives, are widely used at present in daily life. We aimed to investigate the effects of exposure to artificial food colorings during the intrauterine period on the salivary glands in adulthood. ⋯ It was suggested that intrauterine exposure of synthetic food colorings may lead to deterioration of the tissue structure of the salivary glands in adulthood, thereby increasing susceptibility to chronic illnesses including malignancy and chronic inflammation. Therefore, pregnant women should give importance to their nutrition in terms of foods containing synthetic colorings.
