High Heels

Abstract Purpose: High heels have been a fashion mainstay for women for 100s of years despite the well-known fact that wearing them often causes pain in the feet, legs and back. The cause of this pain is complex and the root cause of it has not been determined because a study exploring the biomechanical effects on the vertebral torsion moment on wearers has not been undertaken. Methods: Using video raster stereography, 140 women were measured while in bare foot and while wearing high heels. The collected parameters formed the basis for biomechanical model calculation in order to make more accurate statements about the torsion moment and muscle strength. In addition, a multivariate regression analysis was carried out to evaluate influence factors on pain that occurred while wearing high heels. Results: One hundred and thirty-six women (97 %) aged 18 to 79 years finished the study. The comparison between the measurement points showed a significant difference in the torsion moment. In the regression analysis, the heel height and the frequency of wearing high heels were significant factors influencing the occurrence of pain. Conclusions: Wearing high heels is associated with changes in the posture parameters. The torsion moment is reduced but it does not influence the development of pain which is mainly affected by the height of the heels and the frequency of wearing high heels. In the present study especially, the wearer’s feet were affected.

Objectives: To investigate the correlation between bone density and osteoporosis with some clinical and subclinical factors in patients with dialysis chronic kidney patients. Materials and Methods: Descriptive cross-sectional study, include 163 patients with dialysis chronic kidney disease, from January 2017 to December 2018 at the Department of Haemodyalysis, District 2 Hospital, Ho Chi Minh City. Results: Bone density was negatively correlated with age at the lumbar spine (LS) (r = - 0.225), total hip (total H) (r = - 0.288), femoral neck (FN) (r = - 0.352); with urea at the total H (r = - 0.206), FN (r = - 0.194); with PTH at LS (r = - 0.266), total H (r = - 0.219), FN (r = - 0.168); with β2 Microglobulin at the LS (r = - 0.269). Bone density was positively correlated with glomerular filtration rate at the LS (r = 0.200), FN (r = 0.179); with vitamin D at the LS (r = 0.218) and total H (r = 0.179). Multivariate regression analysis of the risk of decreased bone density at the FN has 2 factors: age (OR = 1.117), PTH (OR = 1.001); at the LS, there are 3 factors: gender (OR = 4.572), PTH (OR=4.078), age (OR = 1.045); at the total H, there are 2 factors: PTH (OR = 3.683), age (OR = 1.117). Osteoporosis in all 3 positions was related to sex (p < 0.05) and age group (p < 0.01). Osteoporosis was associated with PTH, Phosphorus, Aluminum disorders at the FN (p < 0.05), with PTH at the LS (p < 0.05), with PTH, calcium at the total H (p < 0.05). Multivariate regression analysis of the risk of osteoporosis has 3 factors: age (OR = 4.058), PTH (OR = 2.967), female (OR = 2.841). Conclusion: Bone density, osteoporosis is correlated, associated with common factors and factors associated with bone mineral disorders in patients with dialysis chronic kidney disease (CKD - MBD). Key words: End-stage chronic kidney disease, dialysis, bone density

Abstract Objective To evaluate the ability of the pubic arch angle (PAA) as measured by transperineal ultrasonography during labor to predict the delivery type and cephalic pole disengagement mode. Methods The present prospective cross-sectional study included 221 women in singleton-gestational labor ≥ 37 weeks with cephalic fetuses who underwent PAA measurement using transperineal ultrasonography. These measurements were correlated with the delivery type, cephalic pole disengagement mode, and fetal and maternal characteristics. Results Out of the subjects, 153 (69.2%) had spontaneous vaginal delivery, 7 (3.2%) gave birth by forceps, and 61 (27.6%) delivered by cesarean section. For the analysis, deliveries were divided into two groups: vaginal and surgical (forceps and cesarean). The mean PAA was 102 ± 7.5° (range, 79.3–117.7°). No statistically significant difference was observed in delivery type (102.6 ± 7.2° versus 100.8 ± 7.9°, p = 0.105). The occipitoanterior position was seen in 94.1% of the fetuses and the occipitoposterior position in 5.8%. A narrower PAA was found in the group of surgical deliveries (97.9 ± 9.6° versus 102.6 ± 7.3°, p = 0.049). Multivariate regression analysis showed that PAA was a predictive variable for the occurrence of head disengagement in occipital varieties after birth (odds ratio, 0.9; 95% confidence interval, 0.82–0.99; p = 0.026). Conclusion Ultrasonographic measurement of the PAA was not a predictor of delivery type, but was associated with the persistence of occipital varieties after birth.

ObjectivesThe aim of this study was to investigate the scope and severity of the second victim problem among nurses by examining the experiences and effects of patient safety incidents (PSIs) on them.Participants/setting492 nurses who had experienced PSIs and provide direct care in South Korean medical institutions.DesignA cross-sectional study with anonymous online self-report questionnaires was conducted to nurses in order to examine the experiences and effects of PSIs. Scales measuring post-traumatic stress disorder (PTSD) and post-traumatic embitterment disorder (PTED) were used for a more quantitative examination of the effects of PSIs. A χ2 test was administered to find any difference in responses to difficulties due to PSIs between the direct and indirect experience of PSIs. Furthermore, linear regression analysis was conducted to investigate the factors related to scores on the PTSD and PTED scales.ResultsA statistically significant difference was observed for participants who reported having experienced sleeping disorders, with those with direct experience showing 42.4% sleeping disorders and indirect experience at 21.0%. Also, there was a statistically significant difference between the 34.3% with direct experience and the 22.1% with indirect experience regarding having considered duty or job changes (resignation). Regression analysis showed total PTSD scores for indirect experience at 11.97 points (95% CI: −17.31 to −6.63), lower than direct experience. Moreover, those who thought the medical error was not involved in PSI had a total PTED score 4.39 points (95% CI: −7.23 to −1.55) lower than those who thought it was involved.ConclusionsA considerable number of nurses experienced psychological difficulties due to PSIs at levels that could interfere with their work. The effect of PSIs on nurses with direct experience of PSIs was greater compared with those with indirect experience. There need to be psychological support programmes for nurses to alleviate the negative effects of PSIs.

Objectives. Several serum biomarkers have been reported to increase in periodontitis patients as possible mediators linking periodontal inflammation to systemic diseases. However, the relationship between periodontitis and urine biomarkers is still unclear. The aim of this cross-sectional study was to investigate potential urine biomarkers of periodontitis in a Japanese population.Materials and Methods. This study included 108 male subjects, and microbiological and clinical parameters were evaluated as a periodontitis marker. The correlation between nine urine biomarkers (typically used to diagnose kidney disease) and periodontal parameters was analyzed. Based on the findings,β2-microglobulin (β2-MG) and neutrophil gelatinase-associated lipocalin (NGAL) were selected for comparison and multivariate regression analysis, and the Kruskal–Wallis test followed by Bonferroni correction was used to identify differences in their concentrations between the three periodontitis groups (severe, moderate, and no/mild periodontitis).Results.β2-MG and NGAL exhibited a significant correlation with clinical parameters of periodontitis. The prevalence of clinical parameters such as bleeding on probing and number of sites with probing depth (PD) ≥ 6 mm were greater in theβ2-MG high group (≥300 μg/g creatinine) than in the normal group (P=0.017and 0.019, respectively). Multivariate regression analysis indicated that the number of sites with PD ≥ 6 mm was independently associated with urineβ2-MG. Moreover, the number of sites with the clinical attachment level (CAL) ≥ 6 mm was greater in the NGAL high group (highest quartile) (P=0.041). Multivariate regression analysis showed that the number of sites with CAL ≥ 6 mm was associated independently with urine NGAL. Finally,β2-MG was significantly higher in the severe periodontitis subjects compared to the no/mild periodontitis subjects.Conclusion. The significant association between urineβ2-MG or NGAL and periodontitis was revealed. These biomarkers can potentially be used to screen for or diagnose periodontitis. This trial is registered with the UMIN Clinical Trials RegistryUMIN000013485.

Abstract Background Bullying among nurses is a universally recognized problem that has important consequences for nurses, patients and health institutions. This research was conducted with the aim of studying the relationship between role conflict, negative affect and core self-evaluations with bullying in nurses. Methods In this cross-sectional study, 329 nurses were selected by census method. Data were collected using PANAS Scale (negative affect), role conflict questionnaire, Core Self-Evaluations Scale (CSES), and the Negative Acts Questionnaire-Revised (NAQ-R). Data were analyzed using t-test, one way analysis of variance, Pearson correlation coefficient and multiple regression analysis with SPSS software (v. 22). Results The results showed that there is a significant difference between the mean bullying scores in according to gender and ward of affiliation. The influence of other variables (marital status, education level, years of experience, age group and work position) was not meaningful. Pearson correlation analysis results indicated that there is a significant positive relationship between role conflict (r = 0.47) and negative affect (r = 0.56) with bullying. Also there is a significant negative relationship between core self-evaluations and bullying (r = − 0.39). Moreover, regression analysis results revealed that negative affect, role conflict and gender can predict 44% of bullying variance significantly. Conclusions Based on these findings, core self-evaluations, negative affect and role conflict are good factors in predicting bullying among nurses. Consequently, hiring nurses with low negative affect and high core self-evaluations, improving nurses’ self-esteem and self-efficacy and changing workplace conditions in order to reducing role conflict can be useful in reducing workplace bullying.

Objective Several clinical studies have reported that renal impairments are sometimes observed in patients with primary aldosteronism (PA). We analyzed the prevalence of renal impairments in PA patients and identified parameters that increase the risk for them. Design This is a retrospective cross-sectional study. We assessed the PA database established by the multicenter Japan PA study (JPAS). Data were also collected from patients with essential hypertension (EHT). Methods We compared the prevalences of proteinuria and lowered estimated glomerular filtration rate (eGFR) between patients with PA and age, sex, blood pressure and duration of hypertension-matched patients with EHT. We also performed logistic regression analysis to identify parameters that increase the risk for these renal impairments. Results Among 2366 PA patients, the prevalences of proteinuria and lowered eGFR were 10.3 and 11.6%, respectively. The prevalence of proteinuria was significantly higher in PA patients than matched-EHT patients (16.8 vs 4.4%), whereas there was no significant difference in the prevalence of lowered eGFR (17.2 vs 15.0%). The logistic regression analysis also showed that the plasma aldosterone concentration (PAC) significantly increases the risk of proteinuria and lowered eGFR, independent of other known risk factors. Conclusion Plasma aldosterone levels are closely associated with renal impairment in patients with PA. This is contrast to our earlier finding that the PAC was not itself linearly associated with cardiovascular events such as stroke or ischemic heart disease. The mechanism underlying the kidney damage in patients with PA may differ from that affecting the cardiovascular system.

Objective: To detect association of lymphopenia with disease severity and mortality. Methods: Total 874 COVID RT-PCR positive patients admitted to KRL Hospital Islamabad from April 2020 to August 2020 were included in this cross-sectional study. Lymphopenia was defined as <1100 cells/micro–L. WHO categories for disease severity were used. Demographic profile, absolute lymphocyte counts and co-morbidities were recorded. Pearson’s Chi Square test was used to see association between lymphopenia and disease severity as well as disease outcome. Regression analysis was used to see whether lymphopenia would predict disease severity. Comparison of means of absolute lymphocyte count in different disease categories was done by ANOVA. Tukey’s test range was then used to find the means different from each other. P-value ≤ 0.05 was considered statistically significant Results: The mean age of patients was 40±12.3 years. Majority patients (73.9%) were asymptomatic. Lymphopenia was present in 6.9% of total patients. Significant association was found between lymphopenia and disease severity as well as lymphopenia and mortality (< 0.001). Lymphopenia was found to be a predictor of disease severity using regression analysis (< 0.001). Comparison of mean absolute lymphocyte count was significant among disease severity categories (< 0.001). On post-hoc analysis, difference in absolute lymphocyte count was significant moving from asymptomatic to mild and then moderate disease category. However no significant difference was seen in absolute lymphocyte count between moderate and severe categories. Conclusion: Results are compatible with worldwide studies and lymphopenia is valid as a marker of disease severity and mortality doi: https://doi.org/10.12669/pjms.37.7.4085 How to cite this:Toori KU, Qureshi MA, Chaudhry A.

Purpose The aims of this study were to characterize hearing symptoms, habits, and sound pressure levels (SPLs) of personal audio system (PAS) used by young adults; estimate the risk of developing hearing loss and assess whether instructions given to users led to behavioral changes; and propose recommendations for PAS users. Method A cross-sectional study was performed in 50 subjects with normal hearing. Procedures included questionnaire and measurement of PAS SPLs (real ear and manikin) through the users' own headphones and devices while they listened to four songs. After 1 year, 30 subjects answered questions about their usage habits. For the statistical analysis, one-way analysis of variance, Tukey's post hoc test, Lin and Spearman coefficients, the chi-square test, and logistic regression were used. Results Most subjects listened to music every day, usually in noisy environments. Sixty percent of the subjects reported hearing symptoms after using a PAS. Substantial variability in the equivalent music listening level (Leq) was noted ( M = 84.7 dBA; min = 65.1 dBA, max = 97.5 dBA). A significant difference was found only in the 4-kHz band when comparing the real-ear and manikin techniques. Based on the Leq, 38% of the individuals exceeded the maximum daily time allowance. Comparison of the subjects according to the maximum allowed daily exposure time revealed a higher number of hearing complaints from people with greater exposure. After 1 year, 43% of the subjects reduced their usage time, and 70% reduced the volume. A volume not exceeding 80% was recommended, and at this volume, the maximum usage time should be 160 min. Conclusions The habit of listening to music at high intensities on a daily basis seems to cause hearing symptoms, even in individuals with normal hearing. The real-ear and manikin techniques produced similar results. Providing instructions on this topic combined with measuring PAS SPLs may be an appropriate strategy for raising the awareness of people who are at risk.
