Morphometric analysis of the effects of high molecular weight sodium hyaluronate and amino acids mixture on face rejuvenation.

BACKGROUND: Skin aging can be observed at various levels in the epidermis, dermis, and dermo-epidermal junction. Reducing the cosmetic effects of skin aging in the facial region is a widespread demand due to common aesthetic concerns. Consequently, many injectable products on the market promise antiaging effects and cosmetic improvements. We aimed to evaluate the cosmetic efficacy of a high molecular weight sodium hyaluronate and amino acids mixture for the facial region using morphometric analysis. METHODS: This study evaluates the morphometric effectiveness of an injectable mixture (high molecular weight sodium hyaluronate, glycine, L-Proline, L-leucine, L-lysine HCL, L-valine, and L-alanine collagen active ingredient) on the mid-face and jawline in women aged 30-55. We used morphological measurements and digital image data to assess changes and determine effectiveness. Various computational methods were applied simultaneously with statistical tests for validation. RESULTS: The hydration assessment showed a significant increase on both sides of the face. A noticeable decrease was observed in gonion angle, bitragion breadth, bigonion breadth, and marionette wrinkle scale. These results suggest combining mechanical and chemical stimulation from the injection and its components (hyaluronic and amino acids) effectively enhances skin quality. CONCLUSIONS: The study indicates that the mechanical stimulation of the injection improves skin quality. Combining hyaluronic and amino acids (collagen, elastin, and pro-synthetic) is a safe and effective alternative for antiaging treatments.

Impact of Pregnancy on Self-Efficacy and Personal Competence in the Context of Risk of Depression, Mental Health Status, and Satisfaction with Life.

For many women, pregnancy and childbirth are often accompanied by strong emotions related to fear, stress, and anxiety about the health of the woman and her child. This study aimed to assess the effect of pregnancy on the risk of depression, mental health status, and satisfaction with life in women in Poland, Greece, Turkey, Belarus, and Russia. MATERIAL AND METHODS: A cross-sectional comparative study was conducted among 2017 women surveyed, including 584 pregnant women, 528 postpartum women, and 906 women who had never been pregnant (the comparative group) from Poland, Greece, Turkey, Belarus, and Russia. The sample selection was purposive. Surveys were collected between November 2021 and December 2022. The study used the Beck Depression Inventory (BDI) Scale, the Satisfaction with Life Scale (SWLS), the Edinburgh Postpartum Depression Scale (EPDS), the GHQ-28 (General Health Questionnaire), the Schwarzer Generalized Self-Efficacy Scale (GSES), and the KompOs Personal Competence Scale. RESULTS: A significantly lower risk of depression was observed in postpartum women in Poland and amongst pregnant women in Turkey. Pregnant women in Turkey (28.9 points) presented the highest satisfaction with life, while the lowest satisfaction was found amongst pregnant women in Poland and Greece (25.2 and 25.1 points, respectively). In Poland and Belarus, a higher risk of depression was noticed in women who had undergone an artificial abortion. In Turkey, a positive correlation was found in pregnant women concerning the number of children they had with a measure of depression and a negative correlation with life satisfaction. In Greece, non-pregnant women showed no correlation between mental status and scores on the GSES. Scores on satisfaction with SWLS were positively correlated with a sense of power, and the strength of the correlation was similar to results on the BDI and GHQ measures. Postpartum depression, according to the EPDS, was also the most severe in Turkish women. CONCLUSIONS: The highest risk of depression was shown in the control group and amongst pregnant and postpartum women in Turkey and Greece, and the lowest such risk was in Poland. Pregnant and postpartum women showed by far the highest satisfaction with life in Turkey and the lowest in women from Greece. The risk of depression, the level of satisfaction with life, and the mental health of pregnant women were not influenced by the type of last delivery. However, the duration of the last delivery influenced the group from Belarus, and having children affected the mental health of women in the group from Turkey.

A Cluster Validity Index-Based Objective Criteria for Aesthetic Evaluation of Periorbital Treatment.

Purpose: Dark circles and pigmentation around the eyes are common reasons people see dermatologists. An effective assessment of the severity of infraorbital color and texture differences is critical for determining appropriate treatment. Evaluation of the visual severity of cases is mostly based on visual inspection. Treatment efficiency is often measured using patient questionnaires in many cases. The subjectivity of assessments may lead to a prolonged healing process, misdiagnosis, and excessive use of drugs or chemicals. Patients and Methods: In this study, a computer-aided objective evaluation approach was proposed for grading periorbital facial rejuvenation. This approach is based on the analysis of numerical features extracted from different facial regions in digital images. Healing was objectively graded by evaluating data clusters formed using the extracted features. Accordingly, an increase in the visual similarity between paired facial regions is accepted as an indicator of healing, which directly affects the form of data clusters. An intracluster validity index was measured to evaluate the clusters as dense and well separated. A total of 144 facial regions were extracted and examined, and the automatically calculated grades were compared with expert evaluations. Results: The cosmetic effects of the experimental drug were evaluated during the experiments, and expert grades were accepted as the ground truth. The results show that the proposed automated grading approach can evaluate rejuvenation with an accuracy of up to 0.91 accuracy in the upper orbital region. Conclusion: This study concluded that the proposed data-clustering-based approach is promising and can be functional without any special instruments.

Pressure injuries in the operating room: who are at risk?

OBJECTIVE: Operating room (OR)-related pressure injuries (PIs) constitute the majority of all hospital-acquired PIs. The aim of this study is to reveal the prevalence and risk factors of OR-related PIs. METHOD: This study used a cohort design. The data were collected at Acibadem Maslak Hospital in Istanbul between November 2018 and May 2019. The study population consisted of all patients undergoing surgery between these dates (n=612). The haphazard sampling method was used following application of the inclusion criteria. A patient identification form, the 3S intraoperative pressure ulcer risk assesment scale and the Braden Scale were used to collect data. RESULTS: Within the scope of the study, data were collected from 403 patients, of which 57.1% (n=230) were female and 42.9% (n=173) were male; mean age was 47.90±18.15 years. During surgery, PIs were detected in 8.4% of patients. In total, 42 PIs were detected in patients in the study; 92.8% were stage 1 and 7.2% were stage 2. It was determined that the PIs observed in 11.8% (n=4) of the patients were related to device/instrument use and 23.5% (n=8) were related to the positioning device. Risk factors found to be significant in the development of PIs were sex (male) (p=0.049), large amount of bleeding during surgery (p=0.001), dry (p=0.020) and lighter skin (p=0.012), duration of surgery (p=0.001), type of anaesthesia (p=0.015), and medical devices used (p=0.001). CONCLUSION: Early identification of risk factors may reduce OR-related PIs. Guidelines and procedures that focus on preoperative, intraoperative and postoperative evaluation can be developed to reduce and prevent surgery-related PIs and to standardise care.

Assessing the Rejuvenation Effectiveness of a Hyaluronic Acid and Amino Acid Mixture in the Periorbital Region.

Purpose: We performed an assessment of the rejuvenation effect of an amino acid and hyaluronic acid mixture in the periorbital area. Methods: A total of 23 of the 35 participants completed all application sessions and measurements. These 23 women were aged 30-55 years. A hyaluronic acid and amino acid mixture was injected into the participants' periorbital area. Three sessions of application with 15-day intervals were undertaken. Subjects' age, height, weight, smoking status, and sport participation were recorded. A photonumeric dark circle scale and Fitzpatrick's periorbital wrinkling classification were used for evaluation of dark circles and wrinkles in the periorbital area. Anatomical measurements (height of upper and lower eyelids) were done using ImageJ and a skin-analysis system (Observ 520). Results: The 23 women had a mean age of 42.46±9.33 years, mean height 164.46±4.96 cm, and mean weight 63.94±8.26 kg. Before the sessions, the mean heights of the upper eyelids were 1.24±013 cm (right) and 1.21±013 cm (left), while those of the lower eyelids were 0.98±014 cm (right) and 0.97±0.17 cm (left). One month after the third session, mean upper-eyelid heights were 1.30±0.09 cm (right) and 1.28±0.11 cm (left) and lower-eyelid ones 1.02±0.11 cm (right) and 1.02±0.13 cm (left). Dark-circle and wrinkle-scale scores showed significantly positive results between before the sessions and 1 month after the third session. Conclusion: A hyaluronic acid and amino acid mixture can be used to rejuvenation of the periorbital area in women aged 30-55 years.

Impact of pregnancy/childbirth on dispositional optimism in the context of risk of depression, mental health status and satisfaction with life.

Introduction: Life optimism is an inseparable element accompanying every human being. It takes different values depending on the life situation. The present study aimed to measure the level of dispositional optimism in postpartum and pregnant women, compared to women who are not pregnant and have never given birth in Poland, Greece, Turkey, Belarus, and Russia, depending on the level of life satisfaction, risk of depression and mental health. Materials and methods: A case-control study was carried out among 2017 women, including 584 pregnant women, 528 postpartum women, and 906 women who had never been pregnant and had never given birth (control group) from Poland, Greece, Turkey, Belarus, and Russia.The study used the LOT-R Life Orientation Test, the Beck Depression Scale (BDI), the Satisfaction With Life Scale (SWLS), the GHQ- 28, and the Edinburgh Postnatal Depression Scale (EPDS) - only in the postpartum group. Results: Women from the control group showed an average level of optimism, obtaining an average of 16 points in Belarus, 13.4 points in Poland, 13.3 points in Greece, 13.5 points in Turkey, and Russia - 16.3 points. Pregnant women from Belarus had a high level of optimism (17 points), and in other countries, an average level of optimism was in Poland - 14.5 points, Greece - 14.0 points, Turkey - 14.3 points, and Russia - 16.5 points. Women after childbirth had a high level of optimism in Belarus (17.4 points) and Russia (17.2 points), and in other countries had the average level of optimism. In these countries, the lowest level of optimism was found in non-pregnant women. No significant correlation between age and life optimism was found in any group. In Poland, life optimism increased with age in women who had never been pregnant, and in Turkey, in women who were pregnant and after childbirth. Conclusion: Pregnant women from Belarus had a higher level of optimism than other countries. Non-pregnant women had an average level of optimism. Future studies should include larger groups of women and consider other factors that may additionally contribute to dispositional optimism.

Urinary Incontinence Awareness and Attitude Scale (URINAS): A Reliability and Validity Study.

PURPOSE: This purpose of this study was to develop an instrument, the Urinary Incontinence Awareness and Attitude Scale (URINAS), to measure incontinence awareness and attitude, and to evaluate its reliability and validity. DESIGN: Instrument development and psychometric evaluation. SUBJECTS AND SETTING: The URINAS was validated in a group of individuals cared for at a family health center in Samsun, in northern Turkey. The sample comprised 637 respondents. Nearly three-fourths of participants (74.3%, n = 473) were female; their average age was 30.2 years. More than one-third of participants (35.6%, n = 227) reported urinary incontinence (UI). METHODS: Participants completed a questionnaire designed for the study that queried demographic and pertinent clinical data; they also completed the URINAS and the Urogenital Distress Inventory (UDI-6). Explanatory factor analysis was then performed to evaluate validity of the URNAS. Parallel from reliability was evaluated by comparing URINAS and UDI-6 scores to determine parallel form reliability, and the Cronbach α was used to evaluate internal consistency. RESULTS: The URINAS comprises 26 items, divided into 5 subdimensions. The total explanatory variance of the scale is 65.3%, and the factor loadings of the scale items range from 0.38 to 0.85. A significant relationship was found in the correlation analysis between the UDI-6 used for the parallel form and the URINAS. Cronbach α coefficients vary from 0.60 and 0.92. CONCLUSIONS: The URINAS is a valid and reliable instrument that can be used for measuring awareness and attitudes toward UI.

Morphometric and aesthetic analysis of people following application of platelet rich plasma for neck rejuvenation / Análisis morfométrico y estético de personas tras la aplicación de plasma rico en plaquetas para el rejuvenecimiento del cuello

SUMMARY: Several studies have shown beneficial effects of platelet-rich plasma. However, there are very few studies investigating the effectiveness of PRP in the neck region. We aimed to assess the efficacy of PRP injection for neck rejuvenation in females aged 40-55. Fifty-two female consecutive participants had PRP injected and roller applied in three sessions at 3-week intervals. Evaluations were blindly performed by comparing the improvements from the pre- to post-application assessments of anatomical measurements of the neck area based on before and after photography of the participants by two anatomists and three medical aesthetic doctors. The Fitzpatrick Skin Scale, Fitzpatrick Goldman Scale, Wrinkle Assessment Scale (Dedo classification system) and patient satisfaction scale were used for assessment. Additionally, skin stiffness and elasticity, cervicomental angle and jawline angle measurements were performed to analyze anatomical changes in the neck area. The study enrolled 52 volunteers with a mean age of 48.60±5.35 years, mean body weight of 63.21±8.43 kg and mean height of 163.25±4.56 cm. Significant differences were found in the elasticity, jawline angle, cervicomental angle, wrinkling, elasticity G and patient satisfaction scores before and after the treatment. When the results of anatomical parameters and scales are compared, it was revealed that PRP is effective in neck rejuvenation.

RESUMEN: Varios investigaciones han demostrado los efectos beneficiosos del plasma rico en plaquetas. Sin embargo, existen muy pocos estudios que investiguen la efectividad del PRP en la región del cuello. Nuestro objetivo fue evaluar la eficacia de la inyección de PRP para el rejuvenecimiento del cuello en mujeres de 40 a 55 años. A cincuenta y dos mujeres participantes consecutivas se les inyectó PRP y se les aplicó rodillo en tres sesiones a intervalos de 3 semanas. Las evaluaciones se realizaron a ciegas comparando las mejoras de las evaluaciones previas y posteriores a la aplicación de las medidas anatómicas del área del cuello basadas en fotografías de antes y después de los participantes realizadas por dos anatomistas y tres médicos especialistas en cirugía estética. Para la evaluación se utilizaron la escala de piel de Fitzpatrick, la escala de Fitzpatrick Goldman, la escala de evaluación de arrugas (sistema de clasificación Dedo) y la escala de satisfacción del paciente. Además, se realizaron mediciones de rigidez y elasticidad de la piel, ángulo cervicomentoniano y ángulo de la línea de la mandíbula, para analizar los cambios anatómicos en el área del cuello. El estudio inscribió a 52 voluntarios con una edad media de 48,60±5,35 años, un peso corporal medio de 63,21±8,43 kg y una altura media de 163,25±4,56 cm. Se encontraron diferencias significativas en las puntuaciones de elasticidad, ángulo mandibular, ángulo cervicomentoniano, arrugas, elasticidad G y satisfacción del paciente antes y después del tratamiento. Cuando se compararon los resultados de los parámetros anatómicos y las escalas, se reveló que el PRP es eficaz en el rejuvenecimiento del cuello.

Evaluation of the Efficacy of the Three-Component Health Care Management Program HEWCOT in Colorectal Cancer Patients Receiving Chemotherapy.

This study was performed to evaluate effects of education, home visits, web, and phone counseling on chemotherapy symptoms and anxiety in patients with colorectal cancer receiving chemotherapy. This pretest-posttest, quasi-experimental study was conducted in a chemotherapy unit of a hospital between February 2014 and October 2015. Due to dropouts from the study, was completed on 51 participants in the control group and 31 participants in the experimental group. The experimental group was offered a program that includes home visit, nursing education, web counseling, and tele-counseling (HEWCOT), developed by the researchers, to control symptoms and to reduce anxiety. The experimental group less frequently experienced constipation, pain, pricking and numbness in hands and feet, skin and nail problems, ocular problems, weakness, headache, mouth and throat problems, anxiety, and restlessness than the control group. The experimental group had less severe infection symptoms, hair loss, and mouth and throat problems after the interventions than the control group. In this study, the patients followed at home and provided web counseling and tele-counseling experienced less frequently chemotherapy symptoms.

Frequency response of a protein to local conformational perturbations.

Signals created by local perturbations are known to propagate long distances through proteins via backbone connectivity and nonbonded interactions. In the current study, signal propagation from the flexible ligand binding loop to the rest of Protein Tyrosine Phosphatase 1B (PTP1B) was investigated using frequency response techniques. Using restrained Targeted Molecular Dynamics (TMD) potential on WPD and R loops, PTP1B was driven between its crystal structure conformations at different frequencies. Propagation of the local perturbation signal was manifested via peaks at the fundamental frequency and upper harmonics of 1/f distributed spectral density of atomic variables, such as Cα atoms, dihedral angles, or polar interaction distances. Frequency of perturbation was adjusted high enough (simulation length >∼10×period of a perturbation cycle) not to be clouded by random diffusional fluctuations, and low enough (<∼0.8 ns(-1)) not to attenuate the propagating signal and enhance the contribution of the side-chains to the dissipation of the signals. Employing Discrete Fourier Transform (DFT) to TMD simulation trajectories of 16 cycles of conformational transitions at periods of 1.2 to 5 ns yielded Cα displacements consistent with those obtained from crystal structures. Identification of the perturbed atomic variables by statistical t-tests on log-log scale spectral densities revealed the extent of signal propagation in PTP1B, while phase angles of the filtered trajectories at the fundamental frequency were used to cluster collectively fluctuating elements. Hydrophobic interactions were found to have a higher contribution to signal transduction between side-chains compared to the role of polar interactions. Most of in-phase fluctuating residues on the signaling pathway were found to have high identity among PTP domains, and located over a wide region of PTP1B including the allosteric site. Due to its simplicity and efficiency, the suggested technique may find wide applications in identification of signaling pathways of different proteins.
