Abstract
OBJECTIVE To determine the association between diuretic use and falls in community-dwelling older women with urinary incontinence (UI). METHODS We conducted an analytic cross-sectional study using patients' electronic medical records. Patients were women with UI, 65 years or older seen at a urogynecology clinic between January 1, 2018 and September 30, 2019. We used logistic regression analysis to explore the associations between falls and diuretic use. RESULTS The study included 108 women, mean age of 75.2 ±7.5 years. Twenty-two (20%) reported one or more falls within the past year and 32 (30%) were diuretic users. Fall prevalence in diuretic users and non-users were 25% (8/32) and 18.4% (14/76), respectively. Diuretic use was not associated with falls (OR = 0.74, 95%CI = 0.22-2.52). Post-hoc analysis revealed inadequate sample size. CONCLUSIONS Diuretics use may not be a risk factor for falls in ambulatory older women with UI. A larger sample will be needed to confirm.

Abstract
INTRODUCTION AND HYPOTHESIS The objectives were to determine whether a difference exists in the duration of pelvic floor disorder (PFD) symptoms among patients presenting to urogynecologists in two healthcare systems: private and county; and to elucidate differences in baseline characteristics, type of PFDs, symptom severity and management, stratified by healthcare plans. METHODS A multi-center retrospective study was conducted including new patients presenting to three urogynecology clinics between March 2016 and May 2018: one private clinic (site A) and two public clinics in the same county healthcare system (sites B and C). Baseline data included age, race, BMI, parity, and comorbidities. Primary outcome was "time to presentation" defined as PFD duration in months. Secondary outcomes were symptom severity and PFD management, analyzed by healthcare setting and insurance type. RESULTS A total of 1,055 private and 439 public patients were included. Patients in the public setting were younger (54 vs 61 years, p<0.001), largely Hispanic (76% vs 14%, p<0.001), of higher parity (4 vs 3, p=0.001), and had more comorbidities, with a predominance of county-funded healthcare plans. There was no difference in duration of symptoms between the public and private groups respectively (54 vs 56 months, p=0.94). Patients in the public setting had more severe urinary incontinence (3 vs 2 pads/day, p<0.001) and prolapse (stages 3-4, 71% vs 61%, p=0.004); however, they had lower rates of surgical management for stress incontinence and prolapse. Differences in fecal incontinence could not be evaluated owing to small sample size. CONCLUSIONS Public patients presented younger with more severe symptoms but had lower rates of surgery for PFDs traditionally managed surgically.

Abstract
The newly emerging SARS-CoV-2 variants are potential threat and posing new challenges for medical intervention due to high transmissibility and escaping neutralizing antibody (NAb) responses. Many of these variants have mutations in the receptor binding domain (RBD) of SARS-CoV-2 spike protein that interacts with the host cell receptor. Rapid mutation in the RBD through natural selection to improve affinity for host receptor and antibody pressure from vaccinated or infected individual will greatly impact the presently adopted strategies for developing interventions. Understanding the nature of mutations and how they impact the biophysical, biochemical and immunological properties of the RBD will help immensely to improve the intervention strategies. To understand the impact of mutation on the protease sensitivity, thermal stability, affinity for the receptor and immune response, we prepared several mutants of soluble RBD that belong to the variants of concern (VoCs) and interest (VoIs) and characterize them. Our results show that the mutations do not impact the overall structure of the RBD. However, the mutants showed increase in the thermal melting point, few mutants were more sensitive to protease degradation, most of them have enhanced affinity for ACE2 and some of them induced better immune response compared to the parental RBD.

Abstract
Nanoparticles-based multivalent antigen display has the capability of mimicking natural virus infection characteristics, making it useful for eliciting potent long-lasting immune response. Several vaccines are developed against global pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However these subunit vaccines use mammalian expression system, hence mass production with rapid pace is a bigger challenge. In contrast E. coli based subunit vaccine production circumvents these limitations.The objective of the present investigation was to develop nanoparticle vaccine with multivalent display of receptor binding domain (RBD) of SARS-CoV-2 expressed in E. coli. Results showed that RBD entrapped PLA (Poly lactic acid) nanoparticle in combination with aluminum hydroxide elicited 9-fold higher immune responses as compared to RBD adsorbed aluminum hydroxide, a common adjuvant used for human immunization. It was interesting to note that RBD entrapped PLA nanoparticle with aluminum hydroxide not only generated robust and long-lasting antibody response but also provided Th1 and Th2 balanced immune response. Moreover, challenge with 1 µg of RBD alone was able to generate secondary antibody response, suggesting that immunization with RBD-PLA nanoparticleshas the ability to elicit memory antibody against RBD. Plaque assay revealed that the antibody generated using the polymeric formulation was able to neutralize SARS-CoV-2.The RBD entrapped PLA nanoparticles blended with aluminum hydroxide thus has potential to develop asa subunit vaccine against COVID-19.

Abstract
Background: This study aims to examine and determine the role of race/ethnicity in chronic conditions in women diagnosed with gestational diabetes mellitus (GDM) during any of their previous pregnancies. Methods: We used the National Health and Nutrition Examination Survey (NHANES) from2007-2016 to identify women who self-reported prior GDM and chronic disease diagnoses such as cardiovascular disease, hypertension, depression, and type 2 diabetes mellitus (T2DM).We used bivariate analysis using the chi-square test (χ²) and multiple logistic regressions to perform statistical test for associations, taking into consideration design and sample weight. Results: Among participants with prior GDM diagnoses, black women had a 74.4% prevalence of chronic disease, followed by Whites, 58.5% Hispanics, 58.0%, and Asians, 51.9% (P=0.009).Black women with prior GDM diagnoses had 2.4 odds of having chronic conditions compared to Whites (adjusted odds ratio [AOR]=2.40, 95% confidence interval [CI] = 1.28-4.50). In addition, they had higher odds of being former smokers (AOR=1.73, 95% CI=1.01-2.96),current smokers (AOR=1.96, 95% CI=1.06-3.61), having a body mass index (BMI) of 25-29.9(AOR=2.55, 95% CI=1.10-5.87), or a BMI ≥30 (AOR=4.09, 95% CI = 2.05-8.17) compared to their White counterparts. Hispanic women had lower odds of being diagnosed with GDM and associated chronic diseases. Conclusion: Black women with GDM were disproportionally affected and at higher risk to be diagnosed with chronic conditions. Smoking and obesity were strongly associated with chronic disease diagnoses. Our findings also suggest a 'Hispanic Paradox', requiring further study. These findings inform primary care clinicians and Obstetricians, and Gynecologists of at-risk patients who could benefit from lifestyle modification recommendations and counseling.

Abstract
PURPOSE OF REVIEW The proper diagnosis of intrinsic urethral sphincteric deficiency among women with urinary incontinence carries important implications for determining the most effective medical or surgical therapy. Numerous diagnostic tests have been described attempting to make an accurate and comprehensive assessment of urethral function, but all suffer from a lack of standardization or inconsistently quoted reference values. This paper will review the literature on the positive aspects and limitations of commonly employed procedures to diagnose intrinsic urethral sphincteric deficiency. RECENT FINDINGS Specific urodynamic studies, including the 'active' valsalva leak-point pressure and the 'static' urethral pressure profile are commonly used to determine urethral competence. However, these tests measure specific aspects of the continence mechanism under different clinical conditions, which limits the direct comparison between them. More complex techniques such as Doppler ultrasound, video-urodynamics and both static and dynamic magnetic resonance imaging are attempting to validate the urodynamic findings for urethral function. This approach may encourage the standardization of these procedures and parameters for diagnosing intrinsic urethral sphincteric deficiency. SUMMARY A single definitive test for the diagnosis of intrinsic urethral sphincteric deficiency does not exist. Instead, multiple tests should be employed to reach a consensus for the diagnosis. This should include a complete voiding history, simple office examinations, and advanced studies such as urethrocystoscopy, urodynamics and possibly radiological evaluations. Understanding the limitations and variabilities of their equipment and the specific studies utilized should enable practitioners to standardize the approach for determining the extent of urethral dysfunction.

Abstract
OBJECTIVE To assess the natural history of cervical dysplasia during pregnancy and determine the rates for progression or regression post-partum by the severity of the lesion. METHOD This was a retrospective study of 100 patients screened by PAP smear. Lesions were graded by colposcopy and biopsy, and followed post-partum. RESULTS Lesions were graded as ASCUS, LGSIL, and HGSIL. The majority of lesions showed a tendency to regress post-partum (approximately 64%), a trend that was statistically significant (P < .003). A substantial minority (approximately 34%) showed no change in severity of the lesion. The tendency for lesions to progress in severity was very low (approximately 3%). No patient had microinvasive disease. Of patients who had CIS, persistence of this lesion post-partum was present in 67%. CONCLUSION Patients with cervical dysplasia in pregnancy may be followed conservatively with colposcopy and biopsy.
