Effects of Nordic Walking on Oxidant and Antioxidant Status: Levels of Calcidiol and Proinflammatory Cytokines in Middle-Aged Women

Objectives. Nordic walking (NW) is relatively new and popular type of physical exercise with less studied effects than other sports activities. The aim of the study was to analyze possible changes in somatic indices, oxidant and antioxidant status, interleukins, and calcidiol levels in middle-aged women after a 12-week NW training program. Study Design. In this study, we examined the effects of NW training on selected measures and changes in body weight, fat mass, and calcidiol levels. Methods. The study group consisted of 13 women (46 ± 4.2 years), who took part in trainings. Before and after the training program, some anthropometric indices were determined and selected biochemical parameters were measured in blood. Results. NW training led to a significant decrease of the total body mass and fat mass and to an increase in lean body mass (p<0.05). It also contributed to a significant increase in total antioxidative status (TAS) and calcidiol levels (p<0.05). Before training, a reverse correlation between IL-6 and total oxidative capacity (TOC) levels (p<0.05) was found, while after training between IL-6 and calcidiol levels (p≤0.001). Conclusions. 12-week NW training undertaken by premenopausal women not only has a positive effect on body composition but also on the plasma antioxidative capacity

Effect of Three-Week Vibrotherapy on Selected Skin Parameters of Thighs and Buttocks in Women with Cellulite

Background: Cellulite (gynoid lipodystrophy, panniculopathy) affects approximately 85% of women and is related to genetic and hormonal factors, diet, and low physical activity. Vibrotherapy is a promising method of physical therapy to help fight cellulite that has not been studied exhaustively yet. Materials and Methods: Sixty healthy women (age: 19–43 years) with cellulite of at least grade I on the Nurnberg–Muller scale were recruited. The participants were randomly assigned to four groups, receiving a series of 15 vibration treatments in a sitting or lying position for 30 or 60 min. Before and after the first and last treatment, selected skin parameters were measured with the use of Courage and Khazaka equipment. Results: Skin hydration and transepidermal water loss (TEWL) of thighs and buttocks differed significantly at all time points. Post hoc tests showed that each treatment caused a decrease in TEWL but no long-term effect was observed. For skin pH, a significant difference was observed between the measurements I and IV. The lying position caused a greater reduction in the value of the acid–base balance. Conclusions: A series of vibration treatments improved the hydration and pH of the skin. The treatments limited TEWL; however, no long-term effect was observed

Selected hand skin characteristics of laboratory diagnosticians

WstępDługotrwała ekspozycja skóry na mokre środowisko pracy i środki dezynfekcyjne powoduje uszkodzenie bariery naskórkowej, co zaburza jej funkcje ochronne oraz sprzyja rozwojowi dermatoz. Czynniki te występują w pracy diagnosty laboratoryjnego. Celem niniejszej pracy była analiza wybranych cech skóry i zmian skórnych rąk u diagnostów laboratoryjnych.Materiał i metodyW badaniu wzięło udział 50 diagnostów zatrudnionych w jednym z krakowskich laboratoriów. Z badanymi przeprowadzono wywiad oraz oceniono pH ich skóry i jej nawilżenie. Pomiary wykonano na stronie grzbietowej ręki dominującej za pomocą urządzeń SKIN-ph-Meter® PH 905 i Corneometer® CM 825.WynikiUzyskane wartości nawilżenia skóry odpowiadały skórze suchej lub bardzo suchej, a odczyny pH skóry mieściły się w granicach normy. Nie udało się wskazać korelacji między pH skóry a ocenianymi cechami (stażem pracy, liczbą godzin spędzanych w rękawiczkach ochronnych w ciągu doby, liczbą epizodów mycia rąk w ciągu dnia). Wydaje się, że stan nawilżenia skóry dodatnio koreluje z czasem noszenia rękawiczek. Stosowanie preparatów nawilżających dłonie po każdym umyciu wiązało się z nawilżeniem skóry.WnioskiW dobie pandemii COVID-19 ta grupa zawodowa została poddana ogromnym wyzwaniom, a stresory psychiczne i fizyczne (w tym mokre środowisko pracy) będą źródłem przyszłych chorób zawodowych w badanej grupie. Med. Pr. 2020;71(6):725–734BackgroundChronic skin exposure to a wet work environment, as well as disinfectants are factors contributing to epidermal barrier damage. This disturbs its protective functions and promotes the development of dermatoses. All these factors occur in the work environment of a laboratory diagnostician. The aim of the paper was to analyze selected skin parameters and skin lesions in the hands of laboratory diagnosticians.Material and MethodsOverall, 50 laboratory diagnosticians employed in a laboratory in Kraków, Poland, took part in the study. After the interview, the skin pH and moisture content were examined. Measurements were performed on the dorsal side of the dominant hand using the Skin-ph-Meter® PH 905 and Corneometer® CM 825 devices.ResultsThe obtained moisture level values were qualified as dry or very dry skin, and the skin pH was within the reference range. No correlation between the skin pH value and the features examined (professional experience, the number of hours spent in protective gloves during the day, the number of hand washing episodes during the day) was not indicated. The level of skin moisture content seems to positively correlate with the time of wearing gloves. The use of hand moisturizers after each hand washing episode correlated with the level of skin moisture content.ConclusionsDuring the COVID-19 pandemic, this professional group has been facing huge challenges, and mental and physical stressors (including wet work environment) will be the source of future occupational diseases.

Active Ingredients and Natural Raw Materials Used in Foot Care in Diabetic Patients—A Literature Review

Diabetic foot syndrome is the leading cause of limb loss due to non-healing ulcers. Repeated injuries, abnormal foot loads, and ischemia lead to ulcers. Poor shoe selection and inadequate care worsen the situation. Lack of patient education contributes to bacterial infections, tissue necrosis, and amputation. Vigilant observation and regular care can reduce wound size and prevent new wounds. Cleansing, infection control, and pressure relief are crucial in diabetic foot treatment. In this review, the effect of selected active ingredients and natural raw materials used for topical application in the care of diabetic foot was analyzed. The main focus used was on ingredients of natural origin—research studies utilizing emollients, humectants, plant extracts, and animal-derived ingredients were discussed. In addition, research studies on the application of nanomaterials, ozone and stem cells are also discussed. The cosmetics industry and manufacturers of podiatric products play a vital role in diabetic care. They should prioritize proper formulation, optimal ingredient doses, and skin microbiome control. Educating diabetics and using cosmetic products with self-massage elements can reduce the risk of hard-to-heal ulcers

Effect of Whole-Body Cryotherapy on Iron Status and Biomarkers of Neuroplasticity in Multiple Sclerosis Women

The aim of the study was to compare the effect of a series of 20 whole body cryotherapy (WBC) sessions on iron levels and neuroplasticity biomarkers in women with multiple sclerosis (MS) and healthy women. Consent was obtained from the Bioethics Committee at the Regional Medical Chamber in Krakow (87/KBL/OIL/2018; 8 May 2018). The study was registered in the Australian New Zealand Clinical Trials Registry (ACTRN12620001142921; 2 November 2020). The study included 30 people: 15 women with multiple sclerosis (mean age 41.53 &plusmn; 6.98 years) and 15 healthy women (mean age 38.47 &plusmn; 6.0 years). Both groups attended cryotherapy sessions. Venous blood was collected for analysis before the WBC session and after 20 sessions. In women with MS and healthy women, no significant effect of WBC on changes in the level biomarkers of neuroplasticity was found. There were also no statistically significant differences between the groups of the analyzed indices at the beginning of the study

The influence of Finnish sauna treatments on the concentrations of nitric oxide, 3-nitrotyrosine and selected markers of oxidative status in training and non-training men

ObjectivesThe aim of the study was to evaluate the effects of repeated Finnish sauna baths on the concentrations of nitric oxide metabolites (NOx) and 3-nitrotyrosine in relation to pro-oxidative and antioxidative status in young males with different physical activity levels.Material and MethodsThe study was performed on healthy males (aged 20–25 years), representing the training (T, N = 10) and non-training groups (NT, N = 10). The protocol included a series of 10 sauna baths during 3 weeks. One bath consisted of three 15-min sessions, with 2 min recovery. Before the first and the 10th treatment, measurements of body composition, blood pressure, rectal temperature, and plasma concentrations of the total pro-oxidative and antioxidative status, 3-nitrotyrosine and NOx were performed.ResultsA significant increase in physiological parameters during sauna treatments, as well as a significant decrease in the total antioxidative status before the 10th bath, were observed in both groups. The series of sauna baths caused a significant increase in the total antioxidative status in the T group, and a decrease in the total oxidative status in the NT group. A significant decrease in 3-nitrotyrosine in both groups before the last treatment, and also in the T group after the last treatment, was noted. In both groups, a significant increase in NOx concentrations was observed after the first bath.ConclusionsA series of sauna baths contributes to the improvement in the prooxidative/antioxidative balance. The increased production of nitric oxide may lead to a better vascular relaxation and blood flow

The Influence of Whole-Body Cryotherapy or Winter Swimming on the Activity of Antioxidant Enzymes

The aim of this study was to investigate the effect of a series of 20 whole-body cryotherapy sessions and 20 winter swimming sessions on the level of catalase, glutathione peroxidase and superoxide dismutase. The experimental group consisted of 60 people (30 people received cryotherapy and 30 people swam in cold water). The control group—without intervention: 30 people. Each of the three groups was tested twice. Analyzing the changes in the examined indicators, a statistical increase of CAT was observed in men after the use of WBC, as well as an increase of SOD in women and a decrease of SOD in men after the winter swimming season. Regular WS does not seem to place an excessive burden on the body in terms of intensifying oxidative processes. WS sessions once a week can be recommended as an effective method of improving health by causing positive adaptive changes and strengthening the body’s antioxidant barrier. WBC may be used as an adjunct therapy in the treatment of diseases caused by oxidative stress, as it improves the body’s antioxidant capacity. Further research is needed to elucidate antioxidant mechanisms in humans and to determine the short- and long-term effects of exposure to WS and WBC
