In the present study, we have introduced a novel real-time, near-infrared spectroscopy oximeter, the TOE-20 (Astem, Co, Ltd, Kawasaki, Japan), which can simultaneously measure the regional tissue oxygen saturation (rSO) in the skin and subcutaneous tissue at three angiosomes of the foot. Seven patients with chronic limb threatening ischemia who had undergone successful revascularization of the superficial femoral artery were included. The analysis revealed a significant correlation between the rSO and skin perfusion pressure. After revascularization, the rSO and skin perfusion pressure had both increased at the three regions, although the increase at the plantar foot was insignificant. These results indicate that the TOE-20 can be successfully used to monitor the rSO during endovascular treatment.

Rubber seeds, the abundant by-products of rubber tree (Hevea brasiliensis), have been studied for sustainable utilization. Nevertheless, there is no information available regarding activity against skin aging. The study aimed to prepare rubber seed oil (RSO) and evaluate fatty acid compositions by gas chromatography - mass spectrometry (GC/MS), linamarin contamination by ultra-high performance liquid chromatography - tandem mass spectrometry (UPLC-MS/MS).

Objective: To measure the effects kangaroo mother care (KMC) on the regional cerebral oxygen saturation (rSO) measured with near-infrared spectroscopy (NIRS) in premature infants and to study the physiological stability and comfort of the infants during such interventions.
Design: This was a prospective, single-centered, single-blind, 2-arm, parallel-group randomized controlled trial conducted.
Settings: The study was carried out in a tertiary neonatal intensive care unit in Medical Faculty Hospital in Konya/Turkey.

Objectives: Near-infrared spectroscopy (NIRS) is used in critical care settings to measure regional cerebral tissue oxygenation (rSo). However, the accuracy of such measurements has been questioned in darker-skinned individuals due to the confounding effects of light absorption by melanin. In this systematic review, we aim to synthesize the available evidence on the effect of skin pigmentation on rSo readings.

Background: Buried free flaps represent a reconstructive challenge concerning monitoring of vitality, which is fundamental for an early detection of flap failure and prompt surgical salvage. Many flap monitoring techniques have been developed over time, and there is still no consensus concerning the best monitoring technique for buried reconstructions.
Methods: We performed a systematic review of the literature on NIRS monitoring for head and neck free flaps.

The association between the body surface and viscera remains obscure, but a better understanding of the body surface-viscera correlation will maximize its diagnostic and therapeutic values in clinical practice. Therefore, this study aimed to investigate the specificity of body surface-viscera correlation in the pathological state. The study subjects included 40 participants with chronic obstructive pulmonary disease (COPD) in the COPD group and 40 age-matched healthy participants in the healthy control group.
