Abstract Background: Knee osteoarthritis (KOA) occurs more often in middle-aged females. While this age-group experiences comorbid osteoporosis with menopause, its influence on KOA has not been clarified. This epidemiological study aimed to investigate the relationship between menopausal conditions, bone mineral density (BMD), and KOA. Methods: A total of 518 female volunteers who participated in the Iwaki cohort study were enrolled and divided into groups (pre- and post-menopause). Antimullerian hormone (AMH) was measured as a predictive marker for menopause in the pre-menopausal subjects. Weight-bearing anterior-posterior knee radiographs were classified by Kellgren-Lawrence grade, and grade ≥ 2 was defined as definitive KOA (DKOA). Early KOA (EKOA) was defined by Luyten’s criteria, and BMD was measured at a distal radius. The relationship between menopausal condition, BMD, and KOA was analyzed by ROC and regression analysis. Results: Fifty-two participants (10.0%) were diagnosed with EKOA and 204 (39.4%) with DKOA. A total of 393 (75.9%) females began menopause, and the prevalence of DKOA was up to 48.1% and >12.0% in pre-menopause females (p < 0.001, Odds ratio: 6.79). From the ROC analysis in pre-menopausal females, cut-off value of AMH for detecting EKOA was 0.08 ng/ml (AUC: 0.712, p5%CI: 0.527 to 0.897, p-value: 0.025, Odds ratio: 8.28). Regression analysis showed that lower AMH was related to EKOA (p=0.035, Odds ratio: 5.55) and DKOA (p=0.032, Odds 1.59), and lower BMD and high turnover bone metabolism were correlated with DKOA. Conclusions: KOA increased after menopause and was correlated with lower BMD. Furthermore, reduction in AMH was a valuable biomarker for the detection of EKOA.

Background: The relationship between gestational diabetes and postpartum depression (PPD) is poorly understood and seldom studied. Objective: In an effort to explore this issue, the present study investigated the relationship between gestational diabetes and PPD. Methods: The present cross-sectional study was performed with 342 women who were referred to four urban health centers of Hamadan city, west of Iran. We used convenience sampling as a method to recruit women in each health center. We used a researcher-made checklist for gathering data on socio-demographic characteristics and potential risk factors of PPD. The Persian validated version of the Edinburgh Postnatal Depression Scale (EPDS) was used to assess PPD. Univariate and multivariable binary logistic regression was applied to estimate the odds ratio (OR) (95% confidence interval [CI]). Results: Gestational diabetes was identified as the most important risk factor for PPD with OR (95% CI) of 2.19 (1.11, 4.31); P-value=0.02 after adjusting for other variables. Moreover, the adjusted odds ratio showed that PPD among lesseducated women (primary school) was 3.5 times higher compared to women with a university education (OR=3.54, 95% CI: 1.27, 9.84; P-value=0.01). Conclusion: Our findings suggested that PPD is more likely among women with gestational diabetes and those who were less educated. Interventional and educational activities for reducing the risk of PPD can be targeted for use with this population.

Prematurity refers to live births before 37 weeks of gestation and associated with infant morbidity/mortality. Activation of HIF during the final pregnancy phase is believed to play a critical role in the pathogenesis of premature birth and other pregnancy disorders. This study aimed to analyze the relationship between hypoxicstatus and the intensity of HIF-1α expression in a premature placenta.Stored biological materials premature placenta (paraffin blocks) was used in this study. Thirtyone samples of placental hypoxia (H) and 28 samples of premature placental non-hypoxia (N) as controls, were selected non-random consecutively. Subsequently, immunohistochemistry was performed to analyze HIF-1α expression. TheChi-square testwas used to analyze the data and a p-value <0.05 was considered statistically significant.Moderate to strong intensity of HIF-1α expressionwas observed in 58% of hypoxic placenta samples, whereas most of non-hypoxic placental samples(86%) did not expressed or expressed weaklyHIF-1α.There was a significant correlation between the intensity of HIF-1α expression and placental hypoxia (p <0.05) and Odds Ratio (OR) value was 8.31 with a 95% confidence interval (2.32-29.77). The conclusion shows that hypoxic status is associated with intensity of hypoxia inducible factor (HIF)-1α expression in a premature placenta.

Using a special questionnaire adapted for computer evaluation, the prevalence of signs and symptoms of craniomandibular disorders (CMD) and occlusal disharmonies was investigated in a group of 500 adolescents of the Republic of Serbia ranging between 18 and 25 years of age. The presence of signs (symptoms) of CMD and occlusal discrepancies was established using clinical exsamination and evaluated according to the clinical disfunction index (D i) and index of the occlusal state (Oi) proposed by Helkimo et al. 1974. The results of this study revealed that 327 (65.4%) adolescents in the examined group had at least one sign (symptom) of CMD, (Di > 1), and that 271 (54.2%) adolescent had also mild, or severe occlusal discrepancies (Oi > 1). The percentage of persons with signs(symptoms) of CMD was significantly greater in the group having occlusal discrepancies (X = 7.76, P<0.01). The multiple regression analysis of the obtained data and the ODDS ratio confirmed the risk of CMD in the group with occlusal discrepancies to be 2.5 times greater than in the group of adolescents without occlusal discrepancies.

Abstract BACKGROUND: Evidence regarding the relationship between unbound bilirubin levels and acute bilirubin encephalopathy was limited. Therefore, this study set out to investigate whether the unbound bilirubin level was independently related to acute bilirubin encephalopathy in children who underwent exchange transfusion after adjusting for other covariates. METHODS: A total of 46 neonates who underwent exchange transfusion were involved in The First People's Hospital Of Changde City in China from 2016-1-1 to 2018-12-31. The target independent variable and the dependent variable were unbound bilirubin levels measured at baseline and acute bilirubin encephalopathy respectively. Covariates involved in this study included sex, age, birth weight, blood glucose, red blood cell, hemolysis, receive phototherapy before exchange transfusion. RESULTS: The average gestational age of 46 selected participants was 38.6 ± 1.3 weeks old, the average age was 146.5 ± 86.9 hours old, 52.17% of them were male. Result of fully-adjusted binary logistic regression showed unbound bilirubin levels were positively associated with risk of acute bilirubin encephalopathy after adjusting confounders (Odds ratio = 1.41, 95% confidence intervals 1.05-1.91, P value <0.05). CONCLUSION: Unbound bilirubin levels are associated with neonatal acute bilirubin encephalopathy. The mechanism of unbound bilirubin levels leading to neonatal acute bilirubin encephalopathy needs to be further explored.

Abstract Purpose: To research the relationship between serum creatinine and lumbar bone mineral density in people aged <46 years. Methods: A total of 10,968 subjects from the American Nhanes database were included in this cross-sectional study, including 5,744 males (mean age 26.2 years) and 5224 females (mean age 26.7 years). The exposure factor is the serum creatinine value, and the outcome indicator is the lumbar bone mineral density. This study mainly used multivariate linear regression analysis to test the relationship between lumbar bone mineral density and serum creatinine. Results: In the multivariate linear regression analysis, serum creatinine was positively correlated with lumbar bone mineral density (β = 0.122, 95%CI: 0.047-0.198), but in the subgroup analysis stratified by sex, this positive correlation only exists in the female population (Β = 0.186, 95%CI: 0.070-0.301).Conclusions: Our study found that in women aged <46 years with normal renal function, there is a positive correlation between serum creatinine and lumbar BMD. And in those people, the determination of serum creatinine can provide a sensitive biomarker for the early identification and treatment of Osteopenia or osteoporosis.

Abstract Background The change in hip-knee-ankle (HKA) angle after total knee arthroplasty (TKA) may cause an adjustment in hindfoot alignment (HFA). However, the relationship between the changes in HKA angle and HFA is still not well studied. This study aimed to investigate the association between HKA angle and hindfoot alignment changes after TKA for varus knee osteoarthritis. Methods A prospective study was carried out in which 108 patients with varus knee deformities were radiographically and clinically evaluated before and 3 months after TKA. The relationship of change in HFA with correction in HKA angle was investigated. Results The results showed that the HFA was adjusted significantly by 3 months after TKA (p < 0.001), along with improved American Orthopaedic Foot and Ankle Society (AOFAS) ankle hindfoot score (p < 0.001). Next, a univariate correlation and linear regression analysis showed that the change in HFA was weakly correlated with the change in HKA angle (r=-0.262, β=-0.14, 95 % CI: -0.23 to -0.04, P = 0.006). Further stratified analysis and interaction tests revealed that age has a distinct effect on the correlation between the changes in HFA and HKA angle. The correlation was dramatically greater in the group under 65 years (r=-0.474, β=-0.26, 95 % CI: -0.41 to -0.12, P = 0.001), whilst, no correlation was observed in those above 65 years old (r=-0.036, β=-0.02, 95 % CI: -0.14 to 0.11, P = 0.779). Conclusions Our findings indicated that correction of HKA after TKA tend to promote adjustment in the hindfoot alignment toward re-balance of the whole lower limb weight-bearing axis. However, this mechanism obviously weakens in elderly patients. Therefore, if apparent hindfoot deformity exists in these patients before TKA, more perioperative intervention is required for hindfoot adjustment, and even HKA undercorrection may be considered.

Osteoporosis is a disease characterized by deterioration of bone tissue and mass, with an increasing global prevalence. Therefore, the discovery of biomarkers for osteoporosis would help to guide appropriate treatment. Circulating microRNAs (miRNAs) have become increasingly recognized as biomarkers for detecting diseases. However, few studies have investigated the association of circulating miRNA with osteoporosis in the general population. The aim of this study was to identify miRNA associated with osteoporosis in a general resident health check-up for potential use as an osteoporosis biomarker. We conducted a cross-sectional study as part of a health check-up program and recruited 352 volunteers (139 men, 213 women, mean age 64.1±9.6 years). Osteoporosis was diagnosed according to the WHO classification. Twenty-two candidate microRNAs were screened through real-time quantitative PCR, and miRNAs associated with osteoporosis were analyzed using logistic regression analysis including other risk factors. In total, 95 females and 30 males were diagnosed with osteoporosis with bone mineral density tests (BMD: T‐score<−2.5). We found that miR195 was significantly lower in females, while miR150 and miR222 were significantly higher in males. The results of the logistic regression analysis indicated that in females, higher age and lower miR195 (odds ratio: 0.45, 95% confidential interval: 0.03–0.98) were significant risk factors for lower BMD, while the presence of a smoking habit and lower miR150 (odds ratio: 1.35, 95% confidential interval: 1.02–1.79) were significant risk factors for osteoporosis. Serum levels of miR195 and miR150 are independently associated with low bone mineral density in females and males, respectively.

Introduction: One of the simplest methods to predict mesiodistal width of permanent canines and premolars is using Tanaka and Johnston’s prediction formula; however, dental size varies according to race. The study aimed to examine the relationship between incisors mesiodistal width and mandibular first molar’s with mesiodistal width of maxillary and mandibular canines and premolars and to determine the reliability of Tanaka and Johnston prediction formula. Materials & Methods: In the present cross-sectional study, 200 pairs of a dental cast of 12-25 years old were selected and the greatest mesiodistal width of canines and premolars crown in each jaw and incisors and mandibular first molars were measured with a digital caliper with 0.01 resolution. Data were analyzed using regression analysis, t-test (p value < 0.05). Results: There was a significant statistical difference between actual width and Tanaka and Johnston prediction formula in the group under study (p value < 0.001). Moreover, a new linear equation for the prediction of mesiodistal width of maxillary and mandibular canines and premolars based on mesiodistal width of lower incisors and mandibular first molars was developed using regression analysis. Conclusion: In statistical terms, Tanaka and Johnston’s prediction formula is not applicable for the population under study because maxillary estimated measures were a little high and mandibular estimated measures were a little low.
