Abstract Background Low back pain is a prevalent and debilitating condition that affects the health and quality of life of older adults. Older people often consult primary care physicians about back pain, with many also receiving concurrent care from complementary and alternative medicine providers, most commonly doctors of chiropractic. However, a collaborative model of treatment coordination between these two provider groups has yet to be tested. The primary aim of the Collaborative Care for Older Adults Clinical Trial is to develop and evaluate the clinical effectiveness and feasibility of a patient-centered, collaborative care model with family medicine physicians and doctors of chiropractic for the treatment of low back pain in older adults. Methods/design This pragmatic, pilot randomized controlled trial will enroll 120 participants, age 65 years or older with subacute or chronic low back pain lasting at least one month, from a community-based sample in the Quad-Cities, Iowa/Illinois, USA. Eligible participants are allocated in a 1:1:1 ratio to receive 12 weeks of medical care, concurrent medical and chiropractic care, or collaborative medical and chiropractic care. Primary outcomes are self-rated back pain and disability. Secondary outcomes include general and functional health status, symptom bothersomeness, expectations for treatment effectiveness and improvement, fear avoidance behaviors, depression, anxiety, satisfaction, medication use and health care utilization. Treatment safety and adverse events also are monitored. Participant-rated outcome measures are collected via self-reported questionnaires and computer-assisted telephone interviews at baseline, and at 4, 8, 12, 24, 36 and 52 weeks post-randomization. Provider-rated expectations for treatment effectiveness and participant improvement also are evaluated. Process outcomes are assessed through qualitative interviews with study participants and research clinicians, chart audits of progress notes and content analysis of clinical trial notes. Discussion This pragmatic, pilot randomized controlled trial uses a mixed method approach to evaluate the clinical effectiveness, feasibility, and participant and provider perceptions of collaborative care between medical doctors and doctors of chiropractic in the treatment of older adults with low back pain. Trial registration This trial registered in ClinicalTrials.gov on 04 March 2011 with the ID number of NCT01312233.

Abstract Background Low back pain (LBP) is a recognized public health problem, impacting up to 80% of US adults at some point in their lives. Patients with LBP are utilizing integrative health care such as spinal manipulation (SM). SM is the therapeutic application of a load to specific body tissues or structures and can be divided into two broad categories: SM with a high-velocity low-amplitude load, or an impulse "thrust", (HVLA-SM) and SM with a low-velocity variable-amplitude load (LVVA-SM). There is evidence that sensorimotor function in people with LBP is altered. This study evaluates the sensorimotor function in the lumbopelvic region, as measured by postural sway, response to sudden load and repositioning accuracy, following SM to the lumbar and pelvic region when compared to a sham treatment. Methods/Design A total of 219 participants with acute, subacute or chronic low back pain are being recruited from the Quad Cities area located in Iowa and Illinois. They are allocated through a minimization algorithm in a 1:1:1 ratio to receive either 13 HVLA-SM treatments over 6 weeks, 13 LVVA-SM treatments over 6 weeks or 2 weeks of a sham treatment followed by 4 weeks of full spine "doctor's choice" SM. Sensorimotor function tests are performed before and immediately after treatment at baseline, week 2 and week 6. Self-report outcome assessments are also collected. The primary aims of this study are to 1) determine immediate pre to post changes in sensorimotor function as measured by postural sway following delivery of a single HVLA-SM or LVVA-SM treatment when compared to a sham treatment and 2) to determine changes from baseline to 2 weeks (4 treatments) of HVLA-SM or LVVA-SM compared to a sham treatment. Secondary aims include changes in response to sudden loads and lumbar repositioning accuracy at these endpoints, estimating sensorimotor function in the SM groups after 6 weeks of treatment, and exploring if changes in sensorimotor function are associated with changes in self-report outcome assessments. Discussion This study may provide clues to the sensorimotor mechanisms that explain observed functional deficits associated with LBP, as well as the mechanism of action of SM. Trial registration This trial is registered in ClinicalTrials.gov, with the ID number of NCT00830596, registered on January 27, 2009. The first participant was allocated on 30 January 2009 and the final participant was allocated on 17 March 2011.

Abstract Background Positive attitude toward evidence-based practice (EBP) principles in healthcare education may be one of the first steps for motivating a healthcare professional student to later apply EBP principles in clinical decision-making. The objectives for this project were to pilot an international web-based survey of chiropractic students and to describe student attitudes, behaviors, and knowledge about EBP principles. Methods We used SurveyMonkey™ to develop our survey based on an existing questionnaire used to measure basic knowledge, skills and beliefs about EBP among allied healthcare professionals and CAM practitioners. We invited 26 chiropractic educational institutions teaching in English and accredited by official organizations to participate. Academic officials and registrars at participating institutions forwarded an invitation email and two reminders to students between July and September 2010. The invitation contained a link to the 38-item web-based questionnaire. Descriptive statistics were performed for analysis. Results Fourteen institutions from Australia, Canada, US, Denmark and New Zealand participated. Among an estimated 7,142 student recipients of invitation letters, 674 participated in the survey for an estimated response rate of 9.4%. Most respondents reported having access to medical/healthcare literature through the internet, but only 11% read literature every week and 21% did not read literature at all. Respondents generally agreed that the use of research evidence in chiropractic was important. Although 76% of respondents found it easy to understand research evidence and 81% had some level of confidence assessing the general worth of research articles, 71% felt they needed more training in EBP to be able to apply evidence in chiropractic care. Respondents without previous training in research methods had lower confidence in assessing published papers. While more than 60% marked the correct answer for two knowledge items, the mean number of correct answers to the five knowledge questions was 1.3 (SD 0.9). Conclusions Although it is feasible to conduct an international web survey of chiropractic students, significant stakeholder participation is important to improve response rates. Students had relatively positive attitudes toward EBP. However, participants felt they needed more training in EBP and based on the knowledge questions they may need further training about basic research concepts.

Abstract Background Back-related leg pain (BRLP) is a common variation of low back pain (LBP), with lifetime prevalence estimates as high as 40%. Often disabling, BRLP accounts for greater work loss, recurrences, and higher costs than uncomplicated LBP and more often leads to surgery with a lifetime incidence of 10% for those with severe BRLP, compared to 1-2% for those with LBP. In the US, half of those with back-related conditions seek CAM treatments, the most common of which is chiropractic care. While there is preliminary evidence suggesting chiropractic spinal manipulative therapy is beneficial for patients with BRLP, there is insufficient evidence currently available to assess the effectiveness of this care. Methods/Design This study is a two-site, prospective, parallel group, observer-blinded randomized clinical trial (RCT). A total of 192 study patients will be recruited from the Twin Cities, MN (n = 122) and Quad Cities area in Iowa and Illinois (n = 70) to the research clinics at WHCCS and PCCR, respectively. It compares two interventions: chiropractic spinal manipulative therapy (SMT) plus home exercise program (HEP) to HEP alone (minimal intervention comparison) for patients with subacute or chronic back-related leg pain. Discussion Back-related leg pain (BRLP) is a costly and often disabling variation of the ubiquitous back pain conditions. As health care costs continue to climb, the search for effective treatments with few side-effects is critical. While SMT is the most commonly sought CAM treatment for LBP sufferers, there is only a small, albeit promising, body of research to support its use for patients with BRLP. This study seeks to fill a critical gap in the LBP literature by performing the first full scale RCT assessing chiropractic SMT for patients with sub-acute or chronic BRLP using important patient-oriented and objective biomechanical outcome measures.

Abstract Background Complementary and alternative medicine (CAM) is growing in popularity, especially within the pediatric population. Research on CAM practitioners and their specialties, such as pediatrics, is lacking. Within the chiropractic profession, pediatrics is one of the most recently established post-graduate specialty programs. This paper describes the demographic and practice characteristics of doctors of chiropractic with a pediatric diplomate. Methods 218 chiropractors with a pediatric diplomate were invited to complete our survey using either web-based or mailed paper survey methods. Practitioner demographics, practice characteristics, treatment procedures, referral patterns, and patient characteristics were queried with a survey created with the online survey tool, SurveyMonkey©®. Results A total of 135 chiropractors responded (62.2% response rate); they were predominantly female (74%) and white (93%). Techniques most commonly used were Diversified, Activator ®, and Thompson with the addition of cranial and extremity manipulation to their chiropractic treatments. Adjunctive therapies commonly provided to patients included recommendations for activities of daily living, corrective or therapeutic exercise, ice packcryotherapy, and nutritional counseling. Thirty eight percent of respondents' patients were private pay and 23% had private insurance that was not managed care. Pediatrics represented 31% of the survey respondents' patients. Chiropractors also reported 63% of their work time devoted to direct patient care. Health conditions reportedly treated within the pediatric population included back or neck pain, asthma, birth trauma, colic, constipation, ear infection, head or chest cold, and upper respiratory infections. Referrals made to or from these chiropractors were uncommon. Conclusions This mixed mode survey identified similarities and differences between doctors of chiropractic with a pediatric diplomate to other surveys of doctors of chiropractic, CAM professionals, and pediatric healthcare providers. The pediatric diplomate certificate was established in 1993 and provides didactic education over a 2 to 3 year span. The results of this study can be used for historical information as this specialty continues to grow.

- Abstract
Background: To evaluate the effect on urinary symptoms and sexual functioning of Dienogest within a 6-month period of follow-up., Methods: A total of 22 women who were diagnosed as having endometriosis with pelvic pain and irritative urinary symptoms were recruited in this study. The participating patients took a daily dose of 2 mg DNG and underwent outpatient visits at the beginning, 1, 2, 3 and 6 months following treatment., Results: Our data showed a significant improvement of the VAS score since the 1st month till the 6th month after treatment of DNG. OABSS, UDI-6 and IIQ-7 were significantly improved after the treatment of DNG. Besides, serum estradiol was also decreased. Our data also showed that DNG treatment for 6 months did not affect FSFI score. Some patients with heavy menstruation were also improved; however, some patients with regular periods missed or dropped a period after DNG treatment, while other adverse effects were also shown., Conclusion: Our study demonstrated that DNG could not only alleviate endometriosis pelvic pain but reduce urinary symptoms within the 6-month follow-up as well. DNG did not affect sexual function in FSFI score, although some adverse effects were recorded., Competing Interests: Conflicts of interest: The authors declare that they have no conflicts of interest related to the subject matter or materials discussed in this article., (Copyright © 2024, the Chinese Medical Association.)

- Abstract
Background: This study evaluated the associations between inattention, impulsivity, and attention deficit hyperactivity disorder (ADHD) in women with premenstrual dysphoric disorder (PMDD) across the menstrual cycle. Methods: This study enrolled 58 women with PMDD and 50 controls. Symptoms were assessed using the Attention and Performance Self-Assessment Scale and the Dickman Impulsivity Inventory during the pre-ovulatory (PO), mid-luteal (ML), and late luteal (LL) phases of the menstrual cycle. Results: The chi-square analysis revealed a significant association between ADHD and PMDD. Women with PMDD experienced a greater increase in scores of prospective everyday memory problems and difficulties maintaining focused attention from the PO phase to LL phase than the controls; in addition, they had higher scores in dysfunctional impulsivity during the LL phase than the controls. Among women in the PMDD group, those with ADHD had higher scores in prospective everyday memory problems and dysfunctional impulsivity during the PO and ML phases than those without ADHD. Women in the PMDD group without ADHD had a greater increase in scores of prospective everyday memory problems, difficulties maintaining focused attention, and dysfunctional impulsivity from the PO phase to the LL phase than the controls. Conclusion: Our study demonstrated that women with PMDD were more likely to have comorbid ADHD and higher levels of inattention across the menstrual cycle. PMDD was associated with increased impulsivity during the LL phase, independent of ADHD, but it was not associated with a persistent elevation of impulsivity. Furthermore, PMDD women with comorbid ADHD experienced higher inattention and impulsivity during the PO and ML phases than those without it. Thus, ADHD comorbidity should be assessed when assessing or intervening in the symptoms of inattention and impulsivity in women with PMDD.

- Abstract
Bisboronic esters are critical compounds in various research fields, including drug discovery, chemical biology, and material sciences. Currently, the bisboronic esters with reactive functional groups are difficult to synthesize; this is partially due to the lack of a robust method to produce these products with diverse structures and various functional groups at specific locations. To overcome this issue, this study introduced a Ni-catalysis approach to produce bisboronic esters efficiently via cross-coupling and homocoupling using readily available halogenated boronic esters as the starting material under mild reaction conditions. This newly developed strategy enables Csp
2 -Csp2 , Csp3 -Csp3 , and Csp2 -Csp3 couplings, demonstrating a broad substrate scope and excellent compatibility with various functional groups.- Published

- Abstract
The interplay between ovarian hormones, stress, and inflammatory markers in developing premenstrual dysphoric disorder (PMDD) remains inadequately understood. This study investigated the associations of dynamic changes in the levels of estrogen, progesterone, cortisol, brain-derived neurotrophic factor (BDNF), and vascular endothelial growth factor (VEGF) with PMDD during the luteal phase of the menstrual cycle. A total of 58 women with PMDD and 50 healthy women were recruited in this study. These women's estrogen, progesterone, cortisol, BDNF, and VEGF levels were evaluated during the preovulation (PO), mid-luteal (ML), and late-luteal (LL) phases. Furthermore, the severity of P MDD symptoms, depressive symptoms, perceived stress, inattention, craving for sweet foods, and fatigue was assessed. The findings revealed that women with PMDD with higher levels of progesterone during the ML or LL phase or a greater increase (ML-PO) or higher sum (ML + LL) of luteal progesterone level exhibited a greater increase in PMDD symptoms during the luteal phase than did the healthy controls. Furthermore, women with PMDD exhibited higher cortisol levels during the LL phase than did the controls. The BDNF level was negatively correlated with PMDD severity. Furthermore, BDNF and VEGF levels were negatively correlated with inattention and craving for sweet foods among women with PMDD. These results suggest an association between progesterone and the exacerbation of PMDD symptoms during the LL phase. Women with PMDD have relatively high cortisol levels during the LL phase. Future investigations with experimental designs or larger sample sizes are warranted to verify the roles of progesterone and cortisol in the development of PMDD., Competing Interests: Declaration of competing interest None All authors declare no conflict of interest.

- Abstract
Background: This study aimed to investigate the changes in the bladder neck (BN) and urinary symptoms using extracorporeal magnetic innervation (ExMI) therapy before and after performing passive pelvic floor exercises., Methods: Twenty women with stress urinary incontinence (SUI) were assessed by transperineal ultrasound and questionnaires before and after the ExMI therapy from January 2011 to February 2021., Results: The incidence of urinary frequency and SUI were significantly decreased after the therapy (McNemar test, p < 0.01). The therapeutic efficacy of SUI was 75%. A significant decrease was noted in pad test results (paired t test, p < 0.05). At the same time, there was a considerable difference in Urinary Distress Inventory-6 scale measures (paired t test, p < 0.001). However, results for the Incontinence Impact Questionnaire-7 showed a marginally significant difference (paired t test, p = 0.066). Three domains of lubrication, orgasm, and satisfaction in the Female Sexual Function Index showed significant differences (paired t test, p < 0.05). Transperineal ultrasound found that BN mobility and Q-tip straining angle were not statistically significant (paired t test, p > 0.05)., Conclusion: The ExMI is effective for SUI by strengthening the pelvic floor muscle without significantly decreasing BN mobility., Competing Interests: Conflicts of interest: The authors declare that they have no conflicts of interest related to the subject matter or materials discussed in this article., (Copyright © 2023, the Chinese Medical Association.)

- Abstract
Parkinson's disease (PD) is one of the most influential diseases in the world, and the current medication only can relieve the clinical symptoms but not slow the progression of PD. Therefore, we intend to examine the neuroprotective activity of plant-derived compound isotetrandrine (ITD) in vitro and in vivo. In vitro , cells were cotreated with ITD and LPS to detect the inflammatory-related protein and mRNA. In vivo , zebrafish were pretreated with ITD and inhibitors prior to 6-OHDA treatment. Then, the behavior was monitored at 5 dpf. Our result showed ITD inhibited LPS-induced upregulation of iNOS, COX-2 protein expression, and iL-6, inos, cox-2, and cd11b mRNA expression in BV2 cells. The data in zebrafish also demonstrated a significant improvement of ITD on the 6-OHDA-induced locomotor deficiency. ITD also improved 6-OHDA-induced apoptosis in zebrafish PD. We also pharmacologically validated the mechanism with three inhibitors, including LY294002, PI3K inhibitor; LY32141996, ERK inhibitor, SnPP, and HO-1 inhibitors. All of these inhibitors could abolish the neuroprotective effect of ITD partially in locomotor activity. Besides, the molecular level also showed the same trend. Treatment of these inhibitors could significantly abolish ITD-induced antineuroinflammatory and antioxidative stress effects in zebrafish PD. Our study showed ITD possessed a neuroprotective activity in zebrafish PD. The mRNA level also supported our arguments. The neuroprotection of ITD might be through antineuroinflammation and antiapoptosis pathways via PI3K, ERK, and HO-1., Competing Interests: The authors declare that there are no conflicts of interest., (Copyright © 2023 Ching-Hu Wu et al.)

- Abstract
Chemiluminescent probes have become increasingly popular in various research areas including precise tumor imaging and immunofluorescence analysis. Nevertheless, previously developed chemiluminescence probes are mainly limited to studying oxidation reaction-associated biological events. This study presents the first example of bioimaging applicable bicyclic dioxetane chemiluminescent probes with tunable emission wavelengths that range from 525 to 800 nm. These newly developed probes were able to detect the analytes of β-Gal, H
2 O2 , and superoxide with high specificity and a limit of detection of 77 mU L-1 , 96, and 28 nM, respectively. The bioimaging application of the probes was verified in ovarian and liver cancer cells and macrophage cells, allowing the detection of the content of β-Gal, H2 O2 , and superoxide inside the cells. The high specificity allowed us to image the xenografted tumor in mice. We expect that our probes will receive extensive applications in recording complex biomolecular events using noninvasive imaging techniques.- Published

- Abstract
Background: The aim of this study was to assess the correlation between the overall rest-stress distance measured by transperineal ultrasound (TPUS) and Q-tip test angle in women with urodynamic stress incontinence (USI), and determine a cut-off value of rest-stress distance for predicting urethral hypermobility (UH)., Methods: Women with USI scheduled for mid-urethral sling surgery were retrospectively recruited. UH was defined as a Q-tip angle more than or equal to 30 degrees. Ultrasonic measurement of the overall rest-stress distance was defined as the linear distance of bladder-neck position change from resting status to maximal strain., Results: Among the 132 enrolled women, the Pearson correlation coefficient between the overall rest-stress distance in TPUS and Q-tip test angle was 0.9104 (95% CI, 0.8758-0.9357, p < 0.001). In receiver-operating-characteristic-curve analysis, a rest-stress distance of more than 13.3 mm was an optimal cut-off value to predict UH (sensitivity = 76.47%, specificity = 93.3%; area = 0.937, 95% confidence interval: 0.881-0.972)., Conclusions: The overall rest-stress distance in TPUS correlated well with the Q-tip test angle, indicating that it can be an alternative method for the assessment of USI. A rest-stress distance of more than 13.3 mm was an optimal cut-off value to predict UH in women with USI.

Introduction and Hypothesis: The objective was to investigate the surgical volume shifts for primary female stress urinary incontinence (SUI) over a 20-year period (1999-2018) in Taiwan., Methods: This was a retrospective cohort study based on Taiwan's National Health Insurance Research Database. We divided the time-frame into four periods: first period (1999-2003), second period (2004-2008), third period (2009-2013), and fourth period (2014-2018). The variables included major surgical types for SUI (retropubic urethropexy, pubovaginal sling, midurethral sling, etc.), surgeon gender, specialty, surgical volume (high ≥30, median 5-29, low <5), and hospital accreditation level. Reoperation rates within 1 year were analyzed as an outcome measurement., Results: A total of 51,018 patients were identified. Major surgical types increased significantly during the first three periods and slightly decreased during the fourth period. The proportion of surgical volume shifted from high- to medium-, and low-volume, but it reversed during the fourth period. The proportion of SUI surgeries decreased in medical centers, whereas it increased in regional and local hospitals. The proportion of SUI surgeries by female surgeons increased. Similar phenomena occurred in MUS. As for surgeon specialty, major surgical types were performed by gynecologists and urologists equally, whereas MUS were performed more by gynecologists than by urologists. Unexpectedly, 1-year reoperation rates were higher in high-volume surgeons., Conclusions: The surgical trend of SUI surgeries shifted from high- to medium-, and low-volume surgeons, medical centers to regional and local hospitals during the study periods. This implied surgical skills and performance spreading, which may have a great influence on patient and healthcare provider choice of treatment., (© 2022.

- Abstract
Background: To report our experiences of a tape-releasing suture with "long-loop" in women with iatrogenic urethral obstruction following the mid-urethral sling procedure., Methods: A total of 149 women underwent a tape-releasing suture with "Long Loop" during the operation. Post-void residual volume was evaluated after Foley removal. Lower urinary tract symptoms and urodynamic studies were assessed before and six months postoperatively., Results: Nine women out of 149 who underwent mid-urethral sling surgery were found to have iatrogenic urethral obstruction post-operatively based on their urinary symptoms and ultrasound findings. There was no apparent difference between tested groups in mid-urethral sling products and concomitant procedures. 77.8% had successful releases after the first Long-loop manipulation procedure, and 22.2% required two or more releases. However, the SUI cure rate is similar in groups receiving the Long-loop manipulation or not (88.9% and 87.1%, respectively)., Conclusions: We are convinced of the practicability and efficacy of the tape-releasing suture "Long-loop." We adopted subjective and objective means to evaluate both groups before and after a six-month follow-up. The Long-loop manipulation procedure can successfully resolve the iatrogenic urethral obstruction without compromising the effectiveness of mid-urethral sling for the treatment of SUI.

- Abstract
Background: Diabetic cognitive dysfunction (DCD) is one of the most insidious complications of type 2 diabetes mellitus, which can seriously affect the ability to self-monitoring of blood glucose and the quality of life in the elderly. Previous pathological studies of cognitive dysfunction have focused on neuronal dysfunction, characterized by extracellular beta-amyloid deposition and intracellular tau hyperphosphorylation. In recent years, astrocytes have been recognized as a potential therapeutic target for cognitive dysfunction and important participants in the central control of metabolism. The disorder of gut microbiota and their metabolites have been linked to a series of metabolic diseases such as diabetes mellitus. The imbalance of intestinal flora has the effect of promoting the occurrence and deterioration of several diabetes-related complications. Gut microbes and their metabolites can drive astrocyte activation., Aims: We reviewed the pathological progress of DCD related to the "gut microbiota-astrocyte" axis in terms of peripheral and central inflammation, intestinal and blood-brain barrier (BBB) dysfunction, systemic and brain energy metabolism disorders to deepen the pathological research progress of DCD and explore the potential therapeutic targets., Conclusion: "Gut microbiota-astrocyte" axis, unique bidirectional crosstalk in the brain-gut axis, mediates the intermediate pathological process of neurocognitive dysfunction secondary to metabolic disorders in diabetes mellitus., (© 2023 The Authors.

- Abstract
Background: Cervical cancer is highly preventable. The mortality-to-incidence ratio (MIR) is a marker that reflects the available screening interventions and clinical outcomes of cancer treatments. The association between the MIR for cervical cancer and cancer screening disparities among countries is an interesting issue but rarely investigated. The present study sought to understand the association between the cervical cancer MIR and the Human Development Index (HDI)., Methods: Cancer incidence and mortality rates were obtained from the GLOBOCAN database. The MIR was defined as the ratio of the crude mortality rate to the incidence rate. We used linear regression to analyze the correlation of MIRs with the HDI and current health expenditure (CHE) in 61 countries selected based on data quality., Results: The results showed lower incidence and mortality rates and MIRs in more developed regions. In terms of regional categories, Africa had the highest incidence and mortality rates and MIRs. The incidence and mortality rates and MIRs were lowest in North America. Furthermore, favorable MIRs were correlated with a good HDI and high CHE as a percentage of gross domestic product (CHE/GDP) (both p < 0.0001)., Conclusions: The MIR variation for cervical cancer is associated with the ranking of the health system and health expenditure, which further supports the role of cancer screening and treatment disparities in clinical outcomes. The promotion of cancer screening programs can reduce the cervical cancer global incidence and mortality rates and MIRs., (© 2023. The Author(s).)

- Abstract
Purpose: Abnormalities in autonomic function are associated with an overactive bladder (OAB). Heart rate variability is generally used as the sole assessment of autonomic activity; however, we utilized neuECG, a novel method of recording skin electrical signals, to assess autonomic nervous function in healthy controls and patients with OAB before and after treatment., Methods: The prospective sample included 52 participants: 23 patients newly diagnosed with OAB and 29 controls. Autonomic function was assessed in all participants in the morning using neuECG, which analyzed the average skin sympathetic nerve activity (aSKNA) and electrocardiogram simultaneously. All patients with OAB were administered antimuscarinics; urodynamic parameters were assessed before treatments; autonomic and bladder functions using validated questionnaires for OAB symptoms were evaluated before and after OAB treatment., Results: Patients with OAB had significantly higher baseline aSKNA (p = 0.003), lower standard deviation of the normal-to-normal beat intervals, lower root mean square of the successive differences, lower high-frequency, and higher low-frequency than did controls. Baseline aSKNA had the highest value in predicting OAB (AUROC = 0.783, p < 0.001). The aSKNA was negatively correlated with first desire and normal desire in urodynamic studies (both p = 0.025) and was significantly decreased after treatment at rest, stress, and recovery phases, as compared to those before treatment (p = 0.046, 0.017, and 0.017, respectively)., Conclusion: Sympathetic activity increased significantly in patients with OAB compared to that in healthy controls, and decreased significantly post-treatment. Higher aSKNA is associated with decreased bladder volume at which voiding is desired. SKNA may be a potential biomarker for diagnosing OAB., (© 2023.

- Abstract
Enhanced recognition ability, cell uptake capacity, and biostability are characteristics attributed to aptamer-based targeted anticancer agents, and are possibly associated with increased accumulation at the tumor site, improved therapeutic efficacy and reduced negative side effects. Herein, a phosphorothioate backbone modification strategy was applied to regulate the biomedical properties of pancreatic cancer cell-targeting aptamer for efficient in vivo drug delivery. Specifically, the CD71- targeting aptamer XQ-2d was modified into a fully thio-substituted aptamer S-XQ-2d, improving the plasma stability of S-XQ-2d and mitomycin C (MMC)-functionalized S-XQ-2d (MFSX), thus considerably prolonging their half-life in mice. Moreover, the binding and uptake capacities of S-XQ-2d were significantly enhanced. MFSX showed the same level of cytotoxicity as that of MMC against targeted cancer cells, but lower toxicity to non-targeted cells, highlighting its specificity and biosafety. Brief mechanistic studies demonstrated that XQ-2d and S-XQ-2d had different interaction modes and internalization pathways with the targeted cells., (© The Author(s) 2023.

- Abstract
Our study discussed the role of Zfp90 in ovarian cancer (OC) cell lines' sensitivity to cisplatin. We used two OC cell lines, SK-OV-3 and ES-2, to evaluate their role in cisplatin sensitization. The protein levels of p-Akt, ERK, caspase 3, Bcl-2, Bax, E-cadherin, MMP-2, MMP-9 and other drug resistance-related molecules, including Nrf2/HO-1, were discovered in the SK-OV-3 and ES-2 cells. We also used a human ovarian surface epithelial cell to compare the effect of Zfp90. Our outcomes indicated that cisplatin treatment generates reactive oxygen species (ROS) that modulate apoptotic protein expression. The anti-oxidative signal was also stimulated, which could hinder cell migration. The intervention of Zfp90 could greatly improve the apoptosis pathway and block the migrative pathway to regulate the cisplatin sensitivity in the OC cells. This study implies that the loss of function of Zfp90 might promote cisplatin sensitization in OC cells via regulating the Nrf2/HO-1 pathway to enhance cell apoptosis and inhibit the migrative effect in both SK-OV-3 and ES-2 cells.

- Abstract
Background: Our study aims to assess Pixel CO2 laser efficacy for female stress urinary incontinence (SUI). Methods: In the study, 25 women with SUI were included and scheduled for vaginal Pixel CO2 Laser (FemiLift™, Alma Lasers, Israel) treatment. All subjects had a baseline and 6-month post-treatment assessment that included three-dimensional perineal ultrasound and validated questionnaires. Results: Data showed that monthly three-session vaginal Pixel CO2 Laser treatment significantly improved SUI symptoms, as evidenced by validated questionnaires, including UDI-6, IIQ-7, ICIQ, and vaginal laxity questionnaire (p < 0.05). The Pixel CO2 Laser efficacy in vaginal treatment was 20/25 (80%), and the perineal sonography showed that laser treatment significantly decreased bladder neck mobility and middle urethral area (during resting and straining). Permanent adverse events were not found. Conclusions: The results of our study suggested that for the treatment of mild to moderate SUI symptoms, Pixel CO2 Laser is effective and safe; however, more studies and a longer follow-up should be conducted to confirm its efficacy and durability.

- Abstract
The purpose of our study was to investigate the effects of vulvovaginal erbium laser on the genitourinary syndrome of menopause (GSM) and sexual function of postmenopausal women. We conducted a retrospective study of sixty-four postmenopausal women with GSM, and these patients were scheduled for three times of vulvovaginal erbium laser treatment. A baseline and post-treatment vaginal status was assessed by measuring vaginal pH, patients' subjective vulvovaginal atrophy (VVA) symptoms, which included dryness, dyspareunia, itching, and burning. The urinary response to treatment was assessed using ICIQ-SF, UDI-6, IIQ-7, OABSS, and POPDI-6. Sexual function was evaluated using the Female Sexual Function Index (FSFI) before and after vulvovaginal laser therapy. Patient follow-ups were scheduled for 12 months after treatment. A total of sixty-four patients were enrolled in the study. We observed the significant improvement in the percentage of negative symptoms (dryness/dyspareunia/itching/burning) and in lower urinary tracts symptoms evaluated with ICIQ-SF, UDI-6, IIQ-7, OABSS, and POPDI-6 (P < 0.05). Patients' overall satisfaction regarding their sexual life, assessed via Female Sexual Function Index (FSFI), showed significant improvement in its six domains of sexual function (P < 0.05). The pH level of vaginal secretions significantly decreased. No long-term complications were found post-treatment. The Er:YAG vaginal laser procedure is associated with a significant improvement in GSM and sexual function of postmenopausal women. Our result demonstrates that it can be a safe and efficacious treatment for patients with GSM without any serious adverse effects up to 1-year post-treatment. The long-term effects of using vulvovaginal laser in the treatment of GSM should be investigated., (© 2022.

- Abstract
The present study attempted to elucidate whether intravesical instillation of platelet-rich plasma (PRP) could decrease bladder inflammation and ameliorate bladder hyperactivity in ketamine ulcerative cystitis (KIC) rat model. Female Sprague Dawley (S-D) rats were randomly divided into control group, ketamine-treated group, ketamine with PRP treated group, and ketamine with platelet-poor plasma (PPP) treated group. Cystometry and micturition frequency/volume studies were performed to investigate bladder function. The morphological change of bladder was investigated by Mason's trichrome staining. Western blotting analysis were carried out to examine the protein expressions of inflammation, urothelial differentiation, proliferation, urothelial barrier function, angiogenesis and neurogenesis related proteins. The results revealed that treatment with ketamine significantly deteriorated bladder capacity, decreased voiding function and enhanced bladder overactivity. These pathological damage and interstitial fibrosis may via NF-κB/COX-2 signaling pathways and muscarinic receptor overexpression. PRP treatment decreased inflammatory fibrotic biosynthesis, attenuated oxidative stress, promoted urothelial cell regeneration, and enhanced angiogenesis and neurogenesis, thereafter recovered bladder dysfunction and ameliorate the bladder hyperactivity in KIC rat model. These findings suggested that the PRP therapy may offer new treatment options for those clinical KIC patients.

- Abstract
We investigated the storage lower urinary tract symptoms (LUTS) before and after the first dose of coronavirus disease 2019 (COVID-19) vaccine and the association between pre-vaccinated overactive bladder (OAB) and the worsening of storage LUTS following COVID-19 vaccination. This cross-sectional study in a third-level hospital in Taiwan used the validated pre- and post-vaccinated Overactive Bladder Symptom Score (OABSS). Diagnosis of OAB was made using pre-vaccinated OABSS. The deterioration of storage LUTS was assessed as the increased score of OABSS following vaccination. Of 889 subjects, up to 13.4% experienced worsened storage LUTS after vaccination. OAB was significantly associated with an increased risk of worsening urinary urgency (p = 0.030), frequency (p = 0.027), and seeking medical assistance due to urinary adverse events (p < 0.001) after vaccination. The OAB group faced significantly greater changes in OABSS-urgency (p = 0.003), OABSS-frequency (p = 0.025), and total OABSS (p = 0.014) after vaccination compared to those observed in the non-OAB group. Multivariate regression revealed that pre-vaccinated OAB (p = 0.003) was a risk for the deterioration of storage LUTS. In conclusion, storage LUTS may deteriorate after vaccination. OAB was significantly associated with higher risk and greater changes in worsening storage LUTS. Storage LUTS should be closely monitored after COVID-19 vaccination, especially in those OAB patients.

- Abstract
Background: Intestinal intussusception caused by intestinal duplication and ectopic pancreas is extremely rare in the clinic and has not been reported previously., Case Summary: A 29-year-old man was admitted to the hospital for chronic abdominal pain and bloating. The preoperative diagnosis was intestinal obstruction and intussusception. Then, laparotomy, partial small intestinal resection and extraintestinal decompression were performed. Postoperative pathology confirmed intestinal duplication and ectopic pancreas. After surgery, the patient recovered well with no complications. No recurrence was observed after more than 5 mo of follow-up., Conclusion: We report a new case of a young male with intussusception caused by intestinal duplication and ectopic pancreas. Surgery is the main treatment for these conditions. This study aimed to raise awareness and provide information to improve the clinical management of this rare yet serious condition., Competing Interests: Conflict-of-interest statement: The authors have no conflicts of interest or uses of previously copyrighted material to disclose., (©The Author(s) 2022.

- Abstract
We aim to assess the changes in sexual function and vaginal topography using 3-D transperineal ultrasound in stress-incontinent women treated with Er:YAG vaginal laser. Two hundred and twenty women with stress urinary incontinence (SUI) treated with Er:YAG laser were recruited. Assessment before and 6 months after the treatment included vaginal topography using 3-D transperineal ultrasound and sexual function using female sexual function index questionnaire (FSFI). A total of 50 women with complete data showed that the symptomatic improvement was noted in 37 (74%) women. After Er:YAG vaginal laser treatment, significantly decreased width and cross-sectional area in proximal, middle, and distal vagina were found in women with SUI. Nearly all of the domains of FSFI improved significantly after the vaginal laser treatment, except sexual desire. In conclusion, 3-D transperineal ultrasound can be used to conduct vaginal topography. After Er:YAG vaginal laser treatment, the anatomical changes of vaginal shrinkage and the improvement of female sexual function were both noted. The favorable outcome of sexual function partly related to the tightening of vagina, as evidenced by the measurements of the 3-D transperineal ultrasound., (© 2022. The Author(s).)

- Abstract
Background: The purpose of this study was to explore the surgical treatment of intraspinal rib head dislocation (IRH) in children with dystrophic scoliosis secondary to type 1 neurofibromatosis (NF1-DS)., Methods: From 2006 to 2019, 32 of 128 patients with NF1-DS were found to have IRH and enrolled in this study. There were 19 boys and 13 girls with an average age of 8.8±2.6 years. Patients were divided into 2 groups: group A (n=25) without IRH resection and group B (n=7) with IRH resection. The intraspinal rib proportion (IRP), apical vertebra rotation, apical vertebral translation, main thoracic curve Cobb angle, trunk shift and thoracic kyphosis, lumbar lordosis, and sagittal vertebral axis were measured before and after the operation. Spinal injury was graded based on the American Spinal Injury Association (ASIA) Impairment Scale., Results: The study group had a total of 42 IRH. The mean follow-up duration was 46.1±28.7 months. The preoperative IRP in both groups was similar (35.5±14.3% vs. 31.2±15.3%, P=0.522). The postoperative IRP was lower in group B (18.5±11.2% vs. 0%, P=0.002). The IRP in group A decreased from preoperative (31.2±15.3%) to postoperative (18.5±11.2%) (P<0.05). There was no significant difference in the apical vertebra rotation, apical vertebral translation, main thoracic curve Cobb angle, trunk shift, thoracic kyphosis, lumbar lordosis, and sagittal vertebral axis between the 2 groups before surgery and after surgery. Four patients with nerve injury caused by the IRH had full neurological recovery postoperatively. All patients were ASIA grade E at the last follow-up., Conclusions: The surgical treatment of IRH in children with NF1-DS should be determined on the basis of the presence of preoperative neurological symptoms. This study supports the practice of correcting spinal deformities only in patients with mild or no spinal cord injury. If there are obvious neurological symptoms, IRH resection is necessary to relieve spinal cord compression to recover nerve function., Level of Evidence: Level III., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 The Author(s).

- Abstract
This retrospective study used data from patients treated for uterine fibroids with ultrasound-guided high-intensity focused ultrasound (USgHIFU) from April 2015 to April 2019. One hundred and seven patients with solitary fibroids were divided into two groups: (1) the L group with larger fibroids (≥10 cm) and (2) the S group with smaller fibroids (<10 cm). Using magnetic resonance imaging (MRI), we examined the efficacy of high-intensity focused ultrasound (HIFU) ablation by comparing uterine and fibroid volumes before and three months after the procedure. The three-month follow-up clinical visit used a visual analog scale and a uterine fibroid symptom health-related quality of life questionnaire to evaluate clinical symptoms. Both the L and S groups had significant reduction in uterine and fibroid volumes, but the rate was significantly higher in the S group ( p < 0.05). Both groups also had improvements in clinical symptoms, but there was no statistical difference. USgHIFU reduced the size of both large and small fibroids but was most effective on fibroids smaller than 10 cm. Both the L and S groups had improved dysmenorrhea symptoms and quality of life.

- Abstract
Eugenosedin-A (Eu-A) has been shown to protect against hyperglycemia- and hyperlipidemia-induced metabolic syndrome. We investigated the relationship of K
ATP channel activities and insulin secretion by Eu-A in vitro in pancreatic β-cells, and examined the effect of Eu-A on streptozotocin (STZ)/nicotinamide (NA)-induced type 2 diabetes mellitus (T2DM) in vivo. We isolated pancreatic islets from adult male Wistar rats (250-350 g) and identified pancreatic β-cells by the cell size, capacitance and membrane potential. Perforated patch-clamp and inside-out recordings were used to monitor the membrane potential (current-clamp mode) and channel activity (voltage-clamp mode) of β-cells. The membrane potential of β-cells was raised by Eu-A and reversed by the KATP channel activator diazoxide. Eu-A inhibited the KATP channel activity measured at - 60 mV and increased the intracellular calcium concentration ([Ca2+ ]i ), resulting in enhanced insulin secretion. Eu-A also reduced Kir6.2 protein on the cell membrane and scattered in the cytosol under normal glucose conditions (5.6 mM). In our animal study, rats were divided into normal and STZ/NA-induced T2DM groups. Normal rats fed with regular chow were divided into control and control+Eu-A (5 mg/kg/day, i.p.) groups. The STZ/NA-induced diabetic rats fed with a high-fat diet (HFD) were divided into three groups: T2DM, T2DM+Eu-A (5 mg/kg/day, i.p.), and T2DM+glibenclamide (0.5 mg/kg/day, i.p.; a KATP channel inhibitor). Both Eu-A and glibenclamide decreased the rats' blood glucose, prevented weight gain, and enhanced insulin secretion. We found that Eu-A blocked pancreatic β-cell KATP channels, caused membrane potential depolarization, and stimulated Ca2+ influx, thus increasing insulin secretion. Furthermore, Eu-A decreased blood glucose and increased insulin levels in T2DM rats. These results suggested that Eu-A might have clinical benefits for the control of T2DM and its complications., (Copyright © 2021 The Authors. Published by Elsevier Masson SAS..

- Abstract
Background and Objectives : To evaluate the effects of low intensity extracorporeal shock wave therapy (LiESWT) on stress urinary incontinence (SUI). Materials and Methods : This investigation was a multicenter, single-blind, randomized-controlled trial study. Sixty female SUI patients were randomly assigned to receive LiESWT with 0.25 mJ/mm
2 intensity, 3000 pulses, and 3 pulses/s, once weekly for a 4-week (W4) and 8-week (W8) period, or an identical sham LiESWT treatment without energy transmission. The primary endpoint was the changes in urine leakage as measured by a pad test and validated standardized questionnaires, while the secondary endpoint was the changes in a 3-day urinary diary among the baseline (W0), the W4 and W8 of LiESWT, and 1-month (F1), 3-month (F3), and 6-month (F6) follow-up after LiESWT. Results : The results showed that 4 weeks of LiESWT could significantly decrease urine leakage based on the pad test and validated standardized questionnaire scores, as compared to the sham group. Moreover, 8 weeks of LiESWT could significantly reduce urine leakage but increase urine volume and attenuate urgency symptoms, which showed meaningful and persistent improvement at W8, F1, F3, and F6. Furthermore, validated standardized questionnaire scores were significantly improved at W8, F1, F3, and F6 as compared to the baseline (W0). Conclusions : Eight weeks of LiESWT attenuated SUI symptoms upon physical activity, reduced urine leakage, and ameliorated overactive bladder symptoms, which implied that LiESWT significantly improved the quality of life. Our findings suggested that LiESWT could serve as a potentially novel and non-invasive treatment for SUI.- Published

- Abstract
Interstitial cystitis/bladder pain syndrome (IC/BPS) is not only a chronic urinary bladder pain syndrome but is also associated with multifactorial etiology. Our study aimed to test the hypothesis that IC/BPS is associated with subsequent increased risks of outpatient visits and hospitalizations. Using nationwide database, the diagnoses were based on the International Classification Codes (ICD-9-CM) (595.1) of at least three outpatient services during 2002-2008, (n = 27,990) and cystoscopic finding Hunner type and/or glomerulation with pre-audit criteria. All recruited cases monitored for subsequent outpatient visits and hospitalizations for 2 years, including all-cause and specialty-specific departments, were classified according to medical specialty and age group (<40, 40-60, ≥60 years of age). IC/BPS patients have more overall outpatient department (OPD) visits and an overall adjusted incidence rate ratio (IRR) of 1.64. As for specialty, IRRs were higher in psychiatry (2.75), Chinese medicine (2.01), and emergency medicine (2.00), besides urology and gynecology. The IRRs decreased as age advanced (2.01, 1.71, and 1.44, respectively), except for gynecology (2.42, 2.52, and 2.81). A similar phenomenon happens in hospitalization with IRR of 1.69. Due to claim data characteristics, whether ulcer type IC/BPS findings can be deductive to non-ulcer type remains inclusive. Current results indicate the impacts of healthcare burden in broad spectrum about IC/PBS patients. IC/BPS has been suggested to be associated with lower threshold of healthcare visits and some coexisting disease and is comprised of systemic dysregulation, and is beyond the scope of local bladder-urethra disease. Adequate recognition of associated or comorbid factors and possible recommendation or referral for IC/BPS patients can help provide better healthcare quality., Competing Interests: The authors have declared that no competing interests exist.

- Abstract
Background: Cervical elongation is commonly associated with pelvic organ prolapse (POP). It was an identified risk for recurrent prolapse after hysteropexy, requiring additional surgeries. The aim of the study is to investigate the risk factors for uterine cervical elongation among women with POP., Methods: In this single-center retrospective cohort study, women who underwent vaginal total hysterectomy for POP between 2014 and 2016 were collected. The cervical and total uterine lengths were measured by pathologists, while the ratio of cervical length to total uterine length were calculated. The cervical elongation is defined as corpus/cervix ratio ≤ 1.5., Results: A total of 133 patients were enrolled in this study. Among these patients, 43 women had cervical elongation and 90 women had normal length of uterine cervix. We found that age > 65 years old (67.4% vs. 42.2%, p = 0.007), total vaginal length ≥ 9.5 cm (65.1% vs. 45.6%, p = 0.035), uterine weight < 51 gm (72.1% vs. 52.2%, p = 0.03), and Pelvic Organ Prolapse Distress Inventory 6 (POPDI-6) ≥ 12 (30.2% vs. 14.4%, p = 0.032) were associated with the risk of cervical elongation. There were no significant differences on preoperative urodynamic parameters in the two groups., Conclusion: The patient age > 65 years old, the total vaginal length of POP-Q system ≥ 9.5 cm, uterine weight < 51 g, and POPDI-6 ≥ 12 are independent risk factors of cervical elongation in women with POP. For women scheduled for pelvic reconstructive hysteropexy, concomitant cervical amputation should be considered.

- Abstract
Postmenopausal women with ovary hormone deficiency (OHD) are subject to overactive bladder (OAB) symptoms. The present study attempted to elucidate whether low-intensity extracorporeal shock wave therapy (LiESWT) alters bladder angiogenesis, decreases inflammatory response, and ameliorates bladder hyperactivity to influence bladder function in OHD-induced OAB in human clinical trial and rat model. The ovariectomized (OVX) for 12 months Sprague-Dawley rat model mimicking the physiological condition of menopause was utilized to induce OAB and assess the potential therapeutic mechanism of LiESWT (0.12 mJ/mm
2 , 300 pulses, and 3 pulses/second). The randomized, single-blinded clinical trial was enrolled 58 participants to investigate the therapeutic efficacy of LiESWT (0.25 mJ/mm2 , 3000 pulses, 3 pulses/second) on postmenopausal women with OAB. The results revealed that 8 weeks' LiESWT inhibited interstitial fibrosis, promoted cell proliferation, enhanced angiogenesis protein expression, and elevated the protein phosphorylation of ErK1/2, P38, and Akt, leading to decreased urinary frequency, nocturia, urgency, urgency incontinence, and post-voided residual urine volume, but increased voided urine volume and the maximal flow rate of postmenopausal participants. In conclusion, LiESWT attenuated inflammatory responses, increased angiogenesis, and promoted proliferation and differentiation, thereby improved OAB symptoms, thereafter promoting social activity and the quality of life of postmenopausal participants.- Published
