Background and Objectives: Assessment of RANTES level and concentrations of inflammatory cytokines: programmed death ligand 1 (PD-L1), interferon gamma IFN-γ, tumor necrosis factor alpha (TNF-α), transforming growht factor β (TGF-β) (and angiogenesis factors: vascular endothelial growth factor A (VEGF-A) and vascular endothelial growth factor C (VEGF C) in tumor and margin tissues of colorectal cancer (CRC,) and evaluation of RANTES influence on histopathological parameters (microvessel density (MVD), budding, tumor-infiltrating lymphocytes (TILs)), in relation to patients’ clinical features. Materials and Methods: The study used 49 samples of tumor and margin tissues derived from CRC patients. To determinate the concentration of RANTES, PD-L1, IFN-γ, TNF-α, TGF-β, VEGF-A, and VEGF-C, we used the commercially available enzyme-linked immunosorbent assay kit. Additionally, RANTES and PD-L1 expression was assessed with the use of IHC staining in both tumor cells and TILS in randomly selected cases. MVD was assessed on CD34-stained specimens. The MVD and budding were assessed using a light microscope. Results: We found significantly higher levels of RANTES, PD-L1, IFN-γ, TNF-α, TGF-β, VEGF-A, and VEGF-C in the tumor in comparison with the margin. The RANTES tumor levels correlated significantly with those of PD-L1, TNF-α, TGF-β, VEGF-A, and VEGF-C. The RANTES margin levels were significantly associated with the margin levels of all proteins investigated—PD-L1, IFN-γ, TNF-α, TGF-β, VEGF-A, and VEGF-C. Additionally, we observed RANTES- and PD-L1-positive immunostaining in TILs. In a group of 24 specimens, 6 different CRC tumors were positive for RANTES and PD-L1 immunostaining. The IFN-gamma concentration in both tumor and margin and TGF-β in tumor correlated with TILs. TILs were negatively associated with the patients’ disease stage and N parameter. Conclusions: RANTES activity might be associated with angiogenesis, lymphogenesis, and immune escape in CRC. RANTES is an important chemokine that is a part of the chemokine–cytokine network involved in the modulation of TME composition in CRC. Further research may verify which processes are responsible for the associations observed in the study.

Background: The aim of the study was to assess the effect of whole-body cryotherapy (WBC) with subsequent exercise training (WBC group) or exercise-only training (ET group) on endothelium inflammation parameters in patients with ankylosing spondylitis (AS). Methods: The WBC procedure lasted 3 min, and exercise training consisted of one 60 min session a day, which was the same in each group. The ET group was compared to the WBC group. Endothelium (high-sensitivity C-reactive protein (hsCRP), soluble P-Selectin, soluble vascular cell adhesion molecule-1 (sVCAM-1), neopterin), and oxidative stress (lipid hydroperoxide (LHP), protein sulfhydryl (PSH), lipofuscin, paraoxonase-1(PON-1), and albumin) parameters were estimated 1 day before and 1 day after the completion of the study. Results: A significant decrease in hsCRP, sP-Selectin, sVCAM-1, and neopterin concentrations was observed in the WBC group after the treatment. After the treatment, in both groups, LHP and lipofuscin levels and PON-1 activity decreased significantly. The observed drop in these parameters was higher in the WBC group compared to the ET group. Albumin concentration increased in the WBC group after treatment. Conclusion: Procedures of WBC have a beneficial effect on endothelium parameters in AS patients; therefore, this method can be applied in the treatment of this group of patients.

Since the identification of periapical lesions typically requires invasive testing that may adversely affect individuals suffering from concomitant disease, the diagnosis of apical periodontitis remains a challenge. This study aimed to determine the effectiveness of infrared thermal imaging for the detection of asymptomatic odontogenic inflammatory response in patients with a high risk of systemic infections. The examinations were performed using the FLIR T1020 thermal camera. The acquired images were analyzed with a ThermaCAM TM Researcher Pro 2.8 SR-3. Statistical analyses were conducted using the Statistica 10 software. The Mann–Whitney U test was used for data that were not normally distributed or did not meet the assumption of homogeneity of variance, while normally distributed data were analyzed with the t-test. The mean temperature difference between the periapical regions of the suspect and contralateral teeth was found to be greatest at 30 s of mouth opening. This is a preliminary study conducted to evaluate the potential of infrared thermal imaging as a diagnostic tool for the identification and elimination of odontogenic infection foci. Thermography seems to facilitate the quantitative assessment of inflammation by displaying temperature differences between the affected and unaffected regions.

The aim of this work was to develop an original method of thermographic measurement of tongue temperature as a prognostic method in the diagnosis of general diseases. This study examined the temperature distribution on the dorsal and apical surfaces of the tongue in patients with various general diseases and introduced a procedure for cooling the oral cavity. Patients with a high risk of systemic infections were referred to the Oral and Maxillofacial Surgery Outpatient Clinic of the Medical University of Silesia (SUM) in Katowice to identify potential foci of dental infections. They underwent an evaluation of their dentition as well as a prognostic tongue examination using the thermal camera FLIR T540 with a sensitivity of <0.03 K. The obtained results revealed statistically significant differences in the tongue average temperature parameters between the two study groups—healthy patients and patients with disorders. We obtained median temperatures for tongue dorsum (TD) of 35.8 °C and 35.2 °C for healthy patients and patients with disorders, respectively. Also, statistical differences have been obtained for tongue apex (TA) average temperatures. They were 35.5 °C and 34.0 °C for healthy and patients, respectively (p = 0.0001). Similar statistical results presented significant differences in the temperature difference (defined as DT = average temperature 10 min − average temperature 2 min after rinsing of the mouth) of the examined areas of the tongue between the healthy temperature and the unhealthy patient’s temperature. It seems that thermal imaging has potential in the prevention and diagnosis of general diseases.

Over the past 20 years, the high prevalence of diabetes has become a global public health problem. Background: The objective of this study was to develop a non-invasive screening method for diabetes which will enable the detection of the disease at an early stage. Methods: This study included 63 adult patients of both sexes: 30 patients with type 2 diabetes (t2DM) and 33 healthy volunteers. The temperature distribution on the tongue’s dorsum and apex surface was studied in patients after a mouth-cooling procedure had been introduced. The study used an FLIR T540 thermal imaging camera. An analysis of the correlation between the ∆T values of the tongue dorsum and apex and the glycated hemoglobin (HbA1c) level was performed. Results: The median of the average dorsum temperature measured 10 min after mouth rinsing was almost 0.8 [°C] lower than for healthy individuals. Also, studies showed a positive average correlation with a Pearson coefficient of r = 0.46 between the HbA1c level and the ∆T of the tongue dorsum. Conclusions: Tongue temperature measured using the IRT showed a correlation with standard biochemical parameters; it may also differentiate patients and constitute a specific screening method for patients with t2DM.

The main goal of this study was to find out if thermal imaging may be useful in the evaluation of two types of anaesthetic injections—with and without a vasoconstrictor. There were 20 patients (13 women and 7 men) involved in the study. The group was divided into two subgroups. Patients from the first subgroup received infiltration anaesthesia (so-called: IA) of lidocaine (2 mL) and the second group included patients, who received infiltration anaesthesia (so-called: IAN) of lidocaine with 2% noradrenaline (2 mL). The obtained results showed a significant increase in the average temperature 10 min after the injection. In the IA group, the temperature increase was nearly 1.0 °C what was 0.3 °C higher than in the IAN group. Moreover, temperature changes showed a wide plateau between 10 and 25 min after anesthesia administration. The effect of temperature rise was also observed on the contralateral cheek where there was no intervention renders by a contralateral reflex.
