RESUMO
Patients with bipolar disorder (BD) exhibit individual variability in the treatment outcome, and genetic background could contribute to BD itself and the treatment outcome. Leptin levels significantly change in BD patients treated with valproate (VPA), but whether LEPR polymorphisms are associated with treatment response is still unknown. This longitudinal study aimed to investigate the associations between LEPR polymorphisms and VPA treatment response in BD patients who were drug naïve at their first diagnosis of BD. The single-nucleotide polymorphisms (SNPs) of LEPR (rs1137101, rs1137100, rs8179183, and rs12145690) were assayed, and the LEPR polymorphism frequencies of alleles and genotypes were not significantly different between the controls (n = 77) and BD patients (n = 130). In addition, after the 12-week course of VPA treatment in BD patients, the LEPR polymorphisms showed significant effects on changes in disease severity. Moreover, considering the effect of the LEPR haplotype, the frequency of the CAGG haplotype in BD patients was higher than that in the controls (9.3 vs. 2.9%, p = 0.016), and the LEPR CAGG haplotype was associated with a better treatment response than the other haplotypes in BD patients receiving VPA treatment. Therefore, LEPR polymorphisms might serve as mediators involved in the therapeutic action of VPA treatment.

Insulin-sensitizer treatment with metformin is widely used in polycystic ovary syndrome (PCOS). However, the treatment effectiveness shows individual differences in PCOS patients. Organic cation transporter (OCT) 1 and 2 have been reported to mediate metformin transport in the liver and kidney, respectively. In this study, we investigated the association between the polymorphisms of OCT1 and OCT2 and the treatment effectiveness of metformin in PCOS patients. The single nucleotide polymorphisms (SNPs) of OCT1 (rs683369 and rs628031) and OCT2 (rs316019) were analyzed in 87 PCOS and 113 control women. Oral glucose tolerance tests (OGTTs), which represented metformin treatment response, were conducted at the start of treatment and after six-month treatment. The results demonstrated that the SNP frequencies of OCT1 and OCT2 were not associated with PCOS pathophysiology, and that the polymorphisms of OCT1 and OCT2 were not associated with the OGTT parameters at baseline. However, PCOS patients with the G allele of OCT1 rs683369 and/or with the A allele of OCT1 rs628031 had increased insulin sensitivity compared to those with wild-type genotype after receiving metformin treatment. Moreover, the interactions of metformin*SNP were significant in both OCT1 rs683369 (p < 0.001) and rs628031 (p = 0.001) during the treatment period. Taken together, genetic polymorphisms of OCT1 contributed to different metformin treatment responses, and further study is needed to establish personalized treatment programs using a pharmacogenomic algorithm approach in PCOS patients.

Background: Patients with bipolar disorder are at high risk of metabolic disturbance after mood stabilizer treatment. However, the mediators linking the two conditions remain unknown. In this study, we investigated whether fibroblast growth factor-21 (FGF21) was associated with metabolic effects and treatment response in depressed bipolar disorder patients. Methods: We recruited 78 community-dwelling controls and 137 bipolar disorder patients; the latter were interviewed using the Chinese Version of the Modified Schedule of Affective Disorder and Schizophrenia-Life Time. Upon study entry, the bipolar disorder patients were all in a major depressive status, with 17-item Hamilton Depression Rating Scale (HDRS) scores >15. They received valproate (500-1000 mg daily) for 12 weeks, and fluoxetine 20 mg daily was permitted to treat depressive symptoms. Fasting plasma level of FGF21, lipid profiles, and body weight were collected at baseline and after 12 weeks of treatment. Results: At baseline, the demographic characteristics, FGF21 level, and metabolic indices did not differ significantly between the controls and bipolar disorder patients. After 12 weeks of treatment, the FGF21 level (167.7±122.0 to 207.1±162.3 pg/mL, P=.001), body weight and waist circumference had increased significantly (P<.001 and P=.028, respectively). Moreover, the change in FGF21 level was significantly correlated with the changes in HDRS score (r=0.393, P=.002), total cholesterol (r=-0.344, P=.008), and low-density lipoprotein (r=-0.347, P=.007). Conclusions: The central and peripheral mediating effects of FGF21 on bipolar disorder depression treatment might be opposite. High peripheral FGF21 levels might link regulation of metabolic effect and resistance to treatment in bipolar disorder.

INTRODUCTION AND HYPOTHESIS: Stress urinary incontinence (SUI) is common in patients with pelvic organ prolapse. This study hypothesized that SUI may be persistent, de novo, or even cured in women after Elevate™ mesh repair alone and that SUI is associated with urodynamic changes and bladder neck position. METHODS: This secondary analysis included a study cohort of 100 women who underwent Elevate repair. All of them underwent multi-channel urodynamic measurements, 1-h pad test, and bead chain urethrocystography to measure the bladder neck position pre-operatively and at 3 months post-surgery. RESULTS: Fifty-five women with pelvic organ prolapse were continent and 45 had concomitant SUI. Of the 55 continent women, 19 (35%) had de novo SUI after mesh repair surgery and 5 (9%) subsequently underwent anti-incontinence surgery. Of the 45 incontinent women, 11 (24%) became dry after mesh repair without additional anti-incontinence surgery. Of the remaining 34 (76%) with persistent SUI, 15 (33%) underwent subsequent anti-incontinence surgery. Patients with de novo and persistent SUI had a greater decrease in maximal urethral closure pressure (MUCP) after mesh repair (p = 0.03 and 0.01 respectively). Those cured of SUI also had decreased MUCP (p = 0.12), but the bladder neck position while straining was significantly more elevated after mesh repair (p < 0.01) compared with those with persistent SUI. CONCLUSIONS: Elevate mesh reinforcement significantly decreases post-operative MUCP, which is associated with SUI, but can elevate the bladder neck position. Correcting a hyper-mobile urethra is associated with treatment of the concomitant SUI.

INTRODUCTION: Trabecular bone score (TBS) is a novel way for clinicians to evaluate bone quality. It is directly associated with the mechanical strength of bones and helps predict fractures. Vitamin D, a secosteroid that enhances calcium absorption, is commonly used to strengthen the skeletal system. OBJECTIVES: The present analysis aimed to determine the relationship between vitamin D levels and TBS by analyzing data from the National Health and Nutrition Examination Survey. PATIENTS AND METHODS: A total of 4464 persons (2148 men and 2316 women) were included in our study. The participants were analyzed according to sex, obesity status, and Tscore using regression models. RESULTS: We noted a remarkably positive relationship between serum levels of 25hydroxyvitamin D (25[OH]D) and TBS after the results were fully adjusted (ß = 0.319; 95% CI, 0.145-0.494; P <0.001). Tscore analysis showed that serum 25(OH)D levels were related to TBS in the group of participants with normal bone mineral density (Tscore >-1) (ß = 0.311; 95% CI, 0.097-0.525; P = 0.005). However, in the osteopenia (Tscore between -1 and -2.5) and osteoporosis (Tscore <-2.5) group there was no such association (P >0.05). CONCLUSIONS: Our study shows that low serum levels of 25(OH)D may decrease the TBS, which represents the skeletal microarchitecture and is a fracture risk factor in individuals with normal Tscores.

Klotho protein is an anti-aging protein and plays multiple roles in ion-regulation, anti-oxidative stress, and energy metabolism through various pathways. Metabolic syndrome is a combination of multiple conditions that compose of multiple risk factors of cardiovascular disease and type 2 diabetes. Gene regulation and protein expression are discovered associated with metabolic syndrome. We aimed to figure out the correlation between Klotho protein and metabolic syndrome in generally healthy adults. A cross-sectional study of 9976 respondents ≥ 18 years old from the US National Health and Nutrition Examination Survey (2007-2012) by utilizing their soluble Klotho protein concentrations. Multivariate linear regression models were used to analyze the effect of soluble Klotho protein on the prevalence of metabolic syndrome. Soluble Klotho protein concentration was inversely correlated with the presence of metabolic syndromes (p = 0.013) and numbers of components that met the definition of metabolic syndrome (p < 0.05). The concentration of Soluble Klotho protein was negatively associated with abdominal obesity and high triglyceride (TG) in the adjusted model (p < 0.05). Soluble Klotho protein is correlated with changing metabolic syndrome components in adults, especially central obesity and high TG levels. Despite conventional function as co-factor with fibroblast growth factor-23 (FGF23) that regulates phosphate and vitamin D homeostasis, FGF23-independent soluble Klotho protein may act on multiple signal pathways in different organs and tissue in roles of anti-aging and protection from metabolic syndrome.

INTRODUCTION: Ovarian cancer is the most lethal gynecologic malignancy, and its early detection is important for prognosis. Human epididymal secretory protein 4 (HE4) elevation has been studied as a crucial biomarker for this type of cancer. There are currently many organic pollutants in the environ-ment, including polycyclic aromatic hydrocarbons (PAHs). OBJECTIVES: The purpose of our study was to determine relationships between PAH exposure, HE4 levels, and the risk for ovarian cancer. PATIENTS AND METHODS: We included a total of 799 participants over the age of 20 years from the United States National Health and Nutrition Examination Survey datasets (2001-2002) with complete data on urinary PAH metabolites and HE4 levels for multivariable analysis. A multivariable linear regression model was used to investigate the associations between PAH metabolites and HE4 in ovarian cancer. RESULTS: Multivariable linear regression analysis showed that except for 2hydroxyphenanthrene, PAH metabolites correlated positively with ln(HE4) after adjustment for relevant covariates (all P <0.05). Higher quartiles of urinary concentrations of PAH metabolites tended to be associated with higher HE4 levels, with statistical significance in perquartile analysis. A dosedependent relationship between PAH metabolites and HE4 was found (all P trends <0.05). CONCLUSIONS: Exposure to PAHs was found to be associated with elevated HE4 levels and a higher risk for ovarian cancer, which was confirmed by epidemiological evidence. This finding should alert gynecologists and public health experts to pay more attention to the potential role of PAH metabolites in the tumorigenesis of ovarian cancer.

INTRODUCTION: A combustible cigarette is a significant source of acrylamide, which is associated with numerous adverse effects. Electronic cigarette (ecigarette) is an emerging smoking device with uncertain health effects. OBJECTIVES The aim of the study was to explore the exposure risks of acrylamide (AA) by measuring biomarkers, hemoglobinadducts of AA (HbAA) and of glycidamide (HbGA), in serum samples of the general adult population with regard to different smoking status (smoking vs nonsmoking). PATIENTS AND METHODS: This was a crosssectional study of 1657 participants aged 18 years or older from the United States National Health and Nutrition Examination Survey (2015-2016) with recorded patient smoking status and concentrations of HbAA and HbGA. Multivariable linear regression models were used to analyze HbAA and HbGA in different smoking groups (nonsmokers, cigarettes smoking only, ecigarettes smoking only, and dual users). RESULTS: Dual users had the highest HbAA and HbGA concentrations (median [interquartile range], 83.75 [53.28-128.25] pmol/gHb and 61.20 [40.73-89.78] pmol/gHb, respectively). There was a positive association between the use of ecigarettes and the HbAA concentration. The standardized ß coefficients of HbAA and HbGA between the combustible cigarette smokers and nonsmokers in the fully adjusted model were 0.312 and 0.255 (both P <0.001) and those between the dualusers and nonsmokers in the fully adjusted model were 0.396 and 0.342, respectively (both P <0.001). CONCLUSIONS: Ecigarette users are exposed to AA, and users of both combustible and ecigarettes have highest measures of HbAA and HbGA. Aside from the adverse effects caused by ecigarette smoking, coexposure risks of combustible cigarettes and ecigarettes need to be communicated to the public. Further studies are warranted to aid in health promotion.

Background: Certain variables reportedly are associated with a change in left ventricular ejection fraction (LVEF) in heart failure (HF) with reduced ejection fraction (HFrEF). However, literature describing the association between the recovery potential of LVEF and parameters of ventricular remodeling in echocardiography remains sparse. Methods: We recruited 2,148 HF patients with LVEF < 35%. All patients underwent at least two echocardiographic images. The study aimed to compare LVEF alterations and their association with patient characteristics and echocardiographic findings. Results: Patients with "recovery" of LVEF (follow-up LVEF ≥ 50%) were less likely to have prior myocardial infarction (MI), had a higher prevalence of atrial fibrillation (Af), were less likely to have diabetes and hypertension, and had a smaller left atrium (LA) diameter, left ventricular end-diastolic diameter (LVEDD) and left ventricular end-systolic diameter (LVESD), both in crude and in adjusted models (adjustment for age and sex). LVEDD cutoff values of 59.5 mm in men and 52.5 mm in women and LVESD cutoff values of 48.5 mm in men and 46.5 mm in women showed a year-to-year increase in the rate of recovery (follow-up LVEF ≥ 50%)/improvement (follow-up LVEF ≥ 35%), p-value < 0.05 in Kaplan-Meier estimates of the cumulative hazard curves. Conclusions: Our study shows that LVEDD and LVESD increments in echocardiography can be predictors of changes in LVEF in in HF patients with LVEF < 35%. They may be used to identify patients who require more aggressive therapeutic interventions.
RESUMO
Pelvic and acetabular fractures are challenging for orthopedic surgeons, but 3D printing has many benefits in treating these fractures and has been applied worldwide. This study aimed to determine whether 3D printing can shorten the length of hospital stay (LHS) in nongeriatric male adult patients with these fractures. This is a single-center retrospective study of 167 nongeriatric male adult participants from August 2009 to December 2021. Participants were divided into two groups based on whether they received 3D printing assistance. Subgroup analyses were performed. Pearson's correlation and multivariable linear regression models were used to analyze the LHS and the parameters. Results showed that 3D printing-assisted surgery did not affect LHS in the analyzed patients. The LHS was positively correlated with the Injury Severity Score (ISS). Initial hemoglobin levels were negatively associated with LHS in patients aged 18−40 and non-major trauma (ISS < 16) patients. In 40−60-year-old and non-major trauma patients, the duration from fracture to admission was significantly associated with LHS. This study indicates that 3D-assisted technology for pelvic or acetabular fracture surgery for nongeriatric male adults does not influence the LHS. More importantly, the initial evaluation of patients in the hospital was the main predictor of the LHS.
RESUMO
Acetabular or anterior pelvic ring fractures are rare but extremely complicated and challenging injuries for orthopedic trauma surgeons. Three-dimensional (3D) printing technology is widely used in the management of these two fracture types for surgical benefits. Our study aimed to explore whether 3D printing-assisted acetabular or pelvic surgery is beneficial in terms of shortening the length of hospital stay (LHS) and intensive care unit (ICU) stay (ICU LS) for older patients. This retrospective study included two groups of 76 participants over 60 years old who underwent operations with (n = 41) or without (n = 35) guidance by 3D printing. The Mann-Whitney U test was used to analyze continuous variables. Chi-square analysis was applied for categorical variables. Univariable and multivariable linear regression models were used to analyze the factors associated with LHS. The median LHS in the group without 3D printing assistance was 16 (12-21) days, and the median ICU LS was 0 (0-2) days. The median LHS in the group with 3D printing assistance was 17 (12.5-22.5) days, and the median ICU LS was 0 (0-3) days. There was no significant difference in LHS associated with 3D printing assistance vs. that without 3D printing among patients who underwent open reduction and internal fixation for pelvic or acetabular fractures. The LHS positively correlated with the ICU LS whether the operation was 3D printing assisted or not. For fracture surgery in older patients, in addition to the advancement of surgical treatment and techniques, medical teams require more detailed preoperative evaluations, and more personalized medical plans regarding postoperative care to achieve the goals of shortening LHS, reducing healthcare costs, and reducing complication rates.
RESUMO
AIMS: Sarcopenia, one of the primary diseases of the older adult population, is a condition characterized by loss of skeletal muscle mass, strength and functionality. Due to its considerable economic impact, preventive interventions for sarcopenia play an important role in the older adult population. Urine includes many indicators of physiology and pathophysiology. Urine analysis is used to diagnose many different diseases. The goal of this cohort study was to examine the relationship between urine pH level and skeletal muscle mass. METHODS: This community-based cross-sectional study was carried out among 9712 Taiwanese individuals (4992 men and 4720 women). We used urine pH as an independent variable and skeletal muscle mass as a dependent variable. Bioelectric impedance analysis was used to measure the percentage of skeletal muscle mass (PSMM). We collected first fasting morning urine samples after overnight fasting, and urine pH was measured with a dipstick. In the by-sex and by-obesity analyses, we stratified the sample into two subgroups and a linear regression model was used for covariate adjustment. RESULTS: In the fully adjusted model, all-subject analysis showed a statistically significant association between urine pH and the PSMM with a ß coefficient of 0.820 (95% CI 0.615-1.025; P < 0.001). Additionally, by-sex analysis showed that urine pH was related to the PSMM in both sexes, with ß coefficients of 0.261 (95% CI 0.006-0.516; P = 0.045) in men and 0.179 (95% CI 0.029-0.328; P = 0.019) in women. By-obesity status analysis showed that urine pH was related to the PSMM in the body mass index <27 group with a ß coefficient of 0.284 (95% CI 0.101-0.466; P = 0.002) after full adjustment. However, for the body mass index ≥27 group, there was no significant relationship between urine pH and the PSMM (P > 0.05). CONCLUSION: The results showed the impacts of urine pH levels on skeletal muscle mass in both sexes and non-obese populations. Due to its easily accessible and economical characteristics, urine analysis is a convenient way to approach patients with low skeletal muscle mass and predict sarcopenia. Geriatr Gerontol Int 2021; 21: 944-949.

Metabolic syndrome encompasses multiple conditions that increase the risk of cardiovascular disease, and exposure to environmental chemicals can cause metabolic syndrome. This cross-sectional study analyzed data from the US National Health and Nutrition Examination Survey (2003-2006) on 4318 adult participants to assess the association between acrylamide (AA) exposure and metabolic syndrome. Concentrations of hemoglobin-adducted AA (HbAA) and hemoglobin-adducted glycidamide (HbGA) were evaluated. Metabolic syndrome markers related to HbAA and HbGA and the effect of exposure to AA and GA on the prevalence of metabolic syndrome were studied by ANOVA and multivariate logistic regression analyses, respectively. HbAA concentration inversely correlated with the number of metabolic syndrome markers (p < 0.05). An increased HbAA concentration was noted with reduced high triglyceride and low high-density lipoprotein cholesterol levels in the adjusted model (p < 0.05). High fasting plasma glucose level significantly correlated with HbGA concentration in the adjusted model. In conclusion, AA exposure alters metabolic syndrome markers in adults. Additional clinical and animal studies will clarify the role of AA exposure at different stages in the progression of metabolic syndrome-related diseases.

BACKGROUND & AIMS: Micturition dysfunction is a problem in the general population that progresses with aging in both males and females. In the past few decades, the relationship between voiding symptoms and body biochemical status has been a subject of research in several disciplines. Micronutrition is considered to affect different aspects of urinary flow, including neuroregulation, detrusor muscle function, and the structures around the bladder outlet such as the pelvic floor and prostate. Therefore, the objective of our study was to determine the correlation between urine flow rate (UFR) and 25-hydroxyvitamin D (25(OH)D) in the general healthy population. METHODS: Our study involved 3981 adult participants over age 20 from the U.S. National Health and Nutrition Examination Survey datasets (2011-2012). The associations between UFR and serum 25(OH)D concentration were analyzed through multivariate regression models. RESULTS: There was a significant positive association of serum 25(OH)D concentration with UFR (25(OH)D2+25(OH)D3: ß coefficient: 0.003; 95% CI: 0.002, 0.004; p < 0.001, 25(OH)D3; p = 0.003; epi-25(OH)D3, p = 0.020) in an unadjusted model. The substantial associations were still observed in the gender and age subgroups. In analysis of age subgroup, the association of serum 25(OH)D concentration with urine flow rate was significant in fully adjusted model (age<60: 25(OH)D2+25(OH)D3: ß coefficient: 0.004, p < 0.001; 25(OH)D3: p = <0.001, epi-25(OH)D3: p = 0.007; Age≥60: 25(OH)D2+25(OH)D3: ß coefficient: 0.004, p = 0.002; 25(OH)D3: p = 0.001, epi-25(OH)D3: p = 0.001). In gender subgroup analysis, the ß coefficient of 25(OH)D2+25(OH)D3 in male is 0.004 (p < 0.001), and in female is 0.004 (p < 0.001) in fully adjusted model. The higher quartiles of UFR tended to have higher 25(OH)D3 levels with statistically significant in quartile-based analysis. CONCLUSIONS: UFR was associated with increased level of total vitamin D and bioactive form vitamin D3. Vitamin D supplements may be a simple and effective way of improving of bladder function.

BACKGROUND: Pelvic ring injuries constitute only 2 to 8% of all fractures; however, they occur in 20% of polytrauma patients. High-energy pelvic fractures often result in mechanical instability of the pelvic ring. Successful treatment of unstable pelvic ring fractures remains a challenge for orthopedic surgeons. This study presents a novel internal fixation method for stabilizing unstable anterior pelvic ring fractures using a minimally invasive modified pedicle screw-rod fixation (MPSRF) technique. METHODS: This retrospective study included six patients with unstable pelvic ring injuries who underwent MPSRF, with or without posterior fixation. Intraoperative parameters such as blood loss, operative time, complications, and quality of reduction (Matta criteria) were recorded and evaluated by a blinded reviewer. RESULTS: In the present clinical series, the mean operative times and mean blood loss for unilateral versus bilateral anterior ring fixations were 176.0 min versus 295.6 min, and 153.3 mL versus 550.0 mL, respectively. No iatrogenic neuropraxia of the lateral femoral cutaneous nerve or femoral nerve palsy occurred. The reduction quality, graded by the Matta criteria, was excellent in five patients and good in one patient. CONCLUSIONS: There were no infections, delayed unions, nonunions, or loss of reductions during the follow-up period. Only one patient suffered from a broken rod at 4 months postoperatively. The modified technique represents a novel, minimally invasive procedure for the treatment of anterior pelvic ring fractures and offers a reliable and effective alternative to currently available surgical techniques.

OBJECTIVE: Mesh erosion is a serious and not uncommon complication in women undergoing vaginal mesh repair. We hypothesized that mesh erosion is associated with the patient's comorbidities, surgical procedures, and mesh material. The aims of this study were to identify the risk factors and optimal management for mesh erosion. MATERIALS AND METHODS: All women who underwent vaginal mesh repair from 2004 to 2014 were retrospectively reviewed. Data on patients' characteristics, presenting symptoms, treatment and outcomes were collected from their medical records. RESULTS: A total of 741 women underwent vaginal mesh repairs, of whom 47 had mesh erosion. The median follow-up period was 13 months (range 3-84 months). Another nine patients with mesh erosion were referred form other hospitals. Multivariate analysis revealed that concomitant hysterectomy (odds ratio 27.02, 95% confidence interval 12.35-58.82; p < 0.01) and hypertension (odds ratio 5.95, 95% confidence interval 2.43-14.49; p < 0.01) were independent risk factors for mesh erosion. Of these 56 women, 20 (36%) were successfully treated by conservative management, while 36 (64%) required subsequent surgical revision. Compared with surgery, conservative treatment was successful if the size of the erosion was smaller than 0.5 cm (p < 0.01). Six patients (17%) had recurrent erosions after primary revision, but all successfully healed after the second surgery. CONCLUSION: Concomitant hysterectomy and hypertension were associated with mesh erosion. In the management of mesh erosion, conservative treatment can be tried as the first-line treatment for smaller erosions, while surgical repair for larger erosions. Recurrent erosions could happen and requires repairs several times.
