Effect of intake of selected nutrients on skin firmness and elasticity in women.

The proper functioning of the skin is influenced by a proper diet. The purpose of this study was to determine the effect of selected nutrients on selected skin parameters. The study group included 59 women, who were divided into two age groups (under and over 40 years old). A three-day 24-h dietary interview was conducted among the study women and skin parameters were assessed using the Courage + Khazaka method. The results showed LA, ALA, Dietary fiber, Na, K, Mg, Zn, Cu, Vitamin E, Thiamine, Riboflavin, Folates, Vitamins B6, B12 and C correlated with skin elasticity. On the other hand, skin elasticity is influenced exclusively by vitamin D acted on skin firmness. The results obtained indicate that a diet rich in appropriate nutrients has a positive effect on the proper maintenance of important skin parameters.

The effect of laser and dynamic quadripolar radiofrequency therapies on the expression of collagenogenesis proteins in the vaginal epithelium and tissue elasticity in women with genital prolapse

Background. Genital prolapse dramatically affects the quality of life of patients. Various sources show that the relapse rate after surgical treatment is 30 to 60%.
 Aim. To determine and compare the expression levels of collagen metabolism proteins before and after exposure to laser and radio frequency in the postoperative period in postmenopausal patients and to compare ultrasound elastography data to justify using these exposure methods as a rehabilitation program.
 Materials and methods. Histological specimens were collected from 54 patients with postmenopausal POP-Q grade 3 genital prolapse, and an ultrasound examination was made before surgery and after rehabilitation therapy. A real-time polymerase chain reaction method was used to assess the expression level of type I collagen, matrix metalloproteinases (MMP-2, MMP-9), and tissue inhibitors of metalloproteinases (TIMP-1, TIMP-2). Ultrasound examination was performed using the technology of compression elastography with the analysis of the color scale and the coefficient of tissue deformation.
 Results. Data were obtained on the increase in the expression of TIMP-1 by 7 times and TIMP-2 by 4 times in the radiofrequency therapy group compared to the group before treatment, as well as a 64-fold decrease in TIMP-2 expression in the vaginal tissue of women in the group after laser therapy compared to the group before treatment. A significant increase in the expression of TIMP-1 and TIMP-2 genes in vaginal tissue after radiofrequency exposure and a decrease in TIMP-2 after laser exposure demonstrate the compensatory effect of biological markers in response to energy therapy, as well as the remodeling effect of these methods. According to ultrasound, tissue elasticity in patients increased after laser and radiofrequency exposure.
 Conclusion. The results support using radiofrequency and laser therapy in the postoperative period as rehabilitation methods.

Исследование механических свойств костной ткани

Introduction The investigation of the trabecular bone strength in the acetabular area and its dependence on age and gender may provide a theoretical basis for the development of implants for bone replacement. The purpose of this study was to determine the mechanical characteristics of the bone tissue in the supra-acetabular region in patients of different age groups. Materials and methods The cadaveric material of 60 patients was studied and included 20 young patients (age range, 18 to 44), 20 middle-aged patients (age range 45 to 59) and 20 elderly patients (age range, 60 to 74). Fragments of bone tissue 3 × 3 × 1.5 cm in size were removed from the supra-acetabular region using an osteotome. Cylindrical specimens, 6 mm in diameter and 9 mm high, were produced from these fragments using a crown cutter. All samples were subjected to uniaxial compression at a loading rate of 1 mm/ min. Results Comparison of male patients for each of the mechanical parameters did not reveal age differences (p > 0.05). In women of different age groups, the magnitude of elastic deformation was significantly different both by multiple analysis and in pairwise comparison of groups (p < 0.05). There was also no statistically significant difference in the maximum stress and modulus of elasticity in women (p > 0.05). Discussion The data obtained on the mechanical behavior of the trabecular bone and the values of the strength parameters are explained by the spatial arrangement of the fibers of structural proteins, the cross-linking profile of collagen, the degree of matrix mineralization, the structure of hydroxyapatite, and the amount of bound water. Conclusion In male patients, mechanical characteristics of the bone tissue in the supra-acetabular region do not change significantly with age. In women, the value of elastic deformation increases significantly with age. The maximum tensile strength and modulus of elasticity in women of different ages did not show any changes.

Сharacteristics of flexible elastic properties of the carotid arteries in women with arterial hypertension.

The article presents the results of study of the features of the carotid wall structure using ultrasound scanning with differential measurement of intima and media thickness, as well as characteristics of arterial elasticity in women with hypertension without comorbidities. It is shown that in women with hypertension vascular remodeling occurs mainly in the form of thickening of the intima-media due to increase in the media layer and is associated with remodeling of the left heart. Carotid remodeling in women with hypertension is associated with worsening of vascular elasticity - increased vascular stiffness and decreased distension, wherein correlation analysis has shown that mentioned parameters are mostly associated with thickening of the medial layer of the artery wall and increase of internal diameter of the artery, as well as with increase in left ventricular mass. Ultrasound method of estimating elastic characteristics of arterial vessels is informative, relatively inexpensive and safe.

The Utility Of Elastosonography For Assessing Suburethral Tissue Elasticity In Women With Stress Urinary Incontinence

SUMMARY Objective: To determine clinical and diagnostic value of elastosonography (ES) in women with stress urinary incontinence (SUI). Material and methods: Thirty subjects with SUI and 30 subjects without SUI were compared in terms of elastosonographic suburethral tissue elasticity. SUI and bladder neck hypermobility was determined by pad test, Q-tip and stress tests. Measurements points included under bladder (UB), subcutaneous fatty tissue (SC), and the urethra (U) points. Three indices were calculated using these measurements (UB/SC, U/SC and UB/U). The diagnostic value of ES indices were investigated using receiver operating characteristic (ROC) curve analyses. Results: ES UB/SC (AUC=0.962, P=0.001) and U/SC (AUC=0.953, P=0.001) were significant predictors for stress test positivity. ES UB/SC (AUC=0.883, P=0.001) and U/SC (AUC=0.885, P=0.001) were significant predictors for pad test positivity. ES UB/SC (AUC=0.877, P=0.001) and U/SC (AUC=0.857, P=0.001) were significant predictors for Q tip test positivity. In linear regression analysis, stress test positivity was significantly associated with the ES UB/SC (R2=0.84, beta=0.369, P=0.026) and ES U/SC (R2=0.84, beta=0.496, P=0.003). Conclusion: Elastosonographic tissue elasticity determination is a promising tool in bladder neck hypermobility and SUI diagnosis, and may be used as an adjunctive method in selecting patients appropriate for stress urinary incontinence surgery.

A Greater Reduction of Anterior Cruciate Ligament Elasticity in Women Compared to Men as a Result of Delayed Onset Muscle Soreness

Women have a higher risk for anterior cruciate ligament (ACL) injuries compared to men. ACL elasticity and muscle flexibility are major risk factors for knee injuries. The presence of estrogen receptors in connective tissue allows estrogen to change the mechanical properties of muscles and ligaments. Delayed onset muscle soreness (DOMS) happened when begin unaccustomed levels of exercise. Thus, the purpose of this study was to examine ACL elasticity after exercise meant to produce DOMS. As a measure of DOMS, visual analog pain scale and quadriceps strength were measured. One hundred forty healthy students (age: 25.2 ± 2.4 years, height: 165.9 ± 8.0 cm, weight: 62.5 ± 10.5 kg, BMI: 22.6 ± 3.1) participated in this investigation and were divided into two groups: men (n = 70) and women (n = 70). Visual analog pain scale, ACL elasticity, and quadriceps strength were measured before and after the intervention. Subjects participated in the same exercise to induce DOMS. To provoke DOMS, subjects accomplished squats for 5 minutes for 3 rounds. Greater ACL elasticity, greater pain on the subjective pain scale and less muscle strength were found (p < 0.001) in women compared to men before and after exercise. A greater reduction of ACL elasticity (p < 0.05) was found as a result of DOMS in women compared to men. Women are likely to have the damage to the ACL and recover slower compared to men after exercise. Thus, we suggest that women should have more time for musculoskeletal recovery after heavy exercise.

Delivery May Affect Arterial Elasticity in Women

Estrogen is considered to be cardioprotective, but estrogen replacement therapy for postmenopausal women has not shown results for either primary or secondary cardiovascular event prevention. During normal pregnancy, women have significantly higher levels of estrogen and it may be endogenous estrogen that helps prevent atherosclerosis. The present cross-sectional study examined the association between pregnancy followed by delivery and clinical atherosclerosis using the brachial-ankle pulse wave velocity (PWV). A total of 2,560 women undergoing annual health screening at the Institute of Hyogo Prefecture Health Promotion Association in Japan were recruited. Pregnancy history (the age of menarche/menopause and the number of gravida/para), conventional coronary risk factors, and brachial-ankle PWV were recorded. Multivariate linear regression by stepwise selection analysis demonstrated that women who had 1 or more deliveries had a significantly lower PWV, independent of age and other conventional coronary risk factors. Pregnancy followed by delivery may decrease arterial stiffness and prevent the progress of atherosclerosis in women. The contribution of such a pregnancy followed by delivery-related decrease in arterial stiffness to the reduction of cardiovascular disease in women should be further evaluated.

Supplementation with Eskimo® Skin Care improves skin elasticity in women. A pilot study

Objective: To investigate the question of whether supplementation with an oral oil formulation rich in natural stable fish oil can alter skin elasticity, transepidermal water loss (TEWL), and skin roughness in healthy women. Methods: Twenty‐four healthy women aged 40–60 years participated in a single‐blind randomized trial for testing the effect of a proprietary oral supplement for skin nutrition (Eskimo® Skin Care) on skin elasticity, TEWL, and skin roughness. Skin elasticity was measured by an optical cutometer, TEWL by a water‐loss module based upon the vapour gradient principle, and skin roughness with a three‐dimensional microtopography imaging system. Results: Skin elasticity increased by 10% after 3 months of treatment with the supplement, a statistically significant increase in comparison with the control group (p = 0.0298). There was a trend, though not statistically significant, towards a positive influence on the skin's barrier function. No effect on the skin roughness was observed. Conclusion: Eskimo® Skin Care, an oral preparation rich in natural stable fish oil, can improve skin elasticity.

Effects of aging, menopause, and hormone replacement therapy on forearm skin elasticity in women.

To investigate the decline per year in skin elasticity in postmenopausal women and how much hormone replacement therapy (HRT) increased elasticity over 12 months. Observational study of convenience sample. The Cardiovascular Hospital of Central Japan, a cardiovascular medical center. One hundred seventy-six postmenopausal subjects, mean age+/-standard deviation=61.3+/-9.1. In Study 1, skin elasticity was measured in the right forearm using a suction device. Comparisons also were made with 45 premenopausal subjects (aged 34.5+/-9.9). Skin elasticity in the right forearm was measured using the same device at baseline and 12 months after initiation of HRT. In Study 2, 12 postmenopausal subjects (mean age=57.1+/-7.4, range 49-71) received conjugated equine estrogen (0.625 mg/d) in combination with medroxyprogesterone acetate (2.5 mg/d) for 12 months. In Study 1, significant negative correlations between skin elasticity and age and years since menopause were found (r=-0.60, P<.001 for each), as well as a 0.55% decline per year in skin elasticity. In Study 2, 12 months of HRT significantly increased skin elasticity in postmenopausal subjects, by 5.2%. After menopause, skin elasticity declined 0.55% per year; 12 months of HRT increased elasticity by 5.2%.
