Urodynamic insights: exploring the relationship between detrusor overactivity and pelvic organ prolapse in women with urge incontinence.

PURPOSE: Pelvic organ prolapse (POP) and overactive bladder (OAB) commonly affect the aging female population. We aimed to investigate the possible relationship between the two, as reflected by urodynamic studies. METHODS: A retrospective analysis was conducted on women who underwent urodynamic studies at a university-affiliated tertiary medical center from January 2018 to January 2021. Women presenting with urge incontinence and diagnosed with detrusor overactivity (DO) were included in the study. Based on the presence or absence of a modified POP-Q ≥ grade 2, these women were categorized into two groups. Data on general demographics, clinical symptoms, and urodynamic findings were extracted and compared using SPSS. RESULTS: During the study period, 949 urodynamic evaluations were performed. Of these, 303 (31.92%) reported urge incontinence. Out of this subset, 151 (49.83%) were diagnosed with DO. Within this group, 18 (11.9%) had POP, while 134 (88.1%) did not. The POP group had a notably higher incidence of prior vaginal hysterectomy and anterior colporrhaphy (p = 0.02 and p = 0.01, respectively). While most urodynamic parameters were similar between groups, there was a significant increase in hesitancy in the POP group (13 s vs 8 s, p = 0.03). There was a trend indicating a reduced median Q max (12 ml/s vs. 18 ml/s, p = 0.06) and an increased flow time (55 s vs 40 s, p = 0.08) in the POP group. CONCLUSION: The urodynamic profile of the POP group suggests an obstructive voiding pattern. Further longitudinal research is essential to fully understand the relationship between POP and OAB.

Cytosolic dsRNA improves neonatal innate immune responses to adjuvants in use in pediatric vaccines.

Pattern recognition receptors (PRRs) of the innate immune system represent the critical front-line defense against pathogens, and new vaccine formulations target these PRR pathways to boost vaccine responses, through activation of cellular/Th1 immunity. The majority of pediatric vaccines contain aluminum (ALUM) or monophosphoryl lipid A (MPLA) as adjuvants to encourage immune activation. Evidence suggests that elements of the innate immune system, currently being targeted for vaccine adjuvanticity do not fully develop until puberty and it is likely that effective adjuvants for the neonatal and pediatric populations are being overlooked due to modeling of responses in adult systems. We recently reported that the activity of the cytosolic nucleic acid (CNA) sensing family of PRRs is strong in cord blood and peripheral blood of young children. This study investigates the function of CNA sensors in subsets of neonatal innate immune cells and shows that myeloid cells from cord blood can be activated to express T cell costimulatory markers, and also to produce Th1 promoting cytokines. CD80 and CD86 were consistently up-regulated in response to cytosolic Poly(I:C) stimulation in all cell types examined and CNA activation also induced robust Type I IFN and low levels of TNFα in monocytes, monocyte-derived macrophages, and monocyte-derived dendritic cells. We have compared CNA activation to adjuvants currently in use (MPLA or ALUM), either alone or in combination and found that cytosolic Poly(I:C) in combination with MPLA or ALUM can improve expression of activation marker levels above those observed with either adjuvant alone. This may prove particularly promising in the context of improving the efficacy of existing ALUM- or MPLA-containing vaccines, through activation of T cell-mediated immunity.

Maternal morbidity in placenta accreta spectrum following introduction of a multi-disciplinary service compared to standard care: an Irish perspective.

AIM: The purpose of this study is to compare maternal outcomes in patients with placenta accreta spectrum (PAS) when managed as part of a multi-disciplinary team (MDT) compared to standard care. METHODS: Patients in the standard care group were retrospectively identified from pathology records, with patients in the MDT group prospectively collected on an electronic database. Data on maternal demographics, delivery, estimated blood loss (EBL), transfusion requirements, and morbidity were recorded. RESULTS: Sixty patients were diagnosed with PAS between 2006 and 2019, of whom 32 were part of the standard care group and 28 in the MDT group. Compared to standard care, MDT care was associated with an increase in antenatal diagnosis from 56.3 to 92.9% (p < 0.0001), a significant reduction in EBL (4150 mL (800-19500) vs 1975 (495-8500), p < 0.0001), and transfusion requirements (median 7 (0-30) units of RCC vs 1 (0-13), p < 0.0001). CONCLUSION: PAS is associated with significant maternal morbidity and warrants management in an MDT setting with specialist input, which is associated with improved outcomes.

Do you pay to go private?: a single centre comparison of induction of labour and caesarean section rates in private versus public patients.

BACKGROUND: The aim of this study was to compare rates of induction and subsequent caesarean delivery among nulliparous women with private versus publicly funded health care at a single institution. This is a retrospective cohort study using the electronic booking and delivery records of nulliparous women with singleton pregnancies who delivered between 2010 and 2015 in an Irish Tertiary Maternity Hospital (approx. 9000 deliveries per annum). METHODS: Data were extracted from the National Maternity Hospital (NMH), Dublin, Patient Administration System (PAS) on all nulliparous women who delivered a liveborn infant at ≥37 weeks gestation during the 6-year period. At NMH, all women in spontaneous labour are managed according to a standardised intrapartum protocol. Twenty-two thousand two hundred thirty-two women met the inclusion criteria. Of these, 2520 (12.8%) were private patients; the remainder (19,712; 87.2%) were public. Mode of and gestational age at delivery, rates of and indications for induction of labour, rates of pre-labour caesarean section, and maternal and neonatal outcomes were examined. Rates of labour intervention and subsequent maternal and neonatal outcomes were compared between those with and without private health cover. RESULTS: Women attending privately were more than twice as likely to have a pre-labour caesarean section (12.7% vs. 6.5%, RR = 2.0, [CI 1.8-2.2])); this finding persisted following adjustment for differences in maternal age and body mass index (BMI) (adjusted relative risk 1.74, [CI 1.5-2.0]). Women with private cover were also more likely to have induction of labour and significantly less likely to labour spontaneously. Women who attended privately were significantly more likely to have an operative vaginal delivery, whether labour commenced spontaneously or was induced. CONCLUSIONS: These findings demonstrate significant differences in rates of obstetric intervention between those with private and public health cover. This division is unlikely to be explained by differences in clinical risk factors as no significant difference in outcomes following spontaneous onset of labour were noted. Further research is required to determine the roots of the disparity between private and public decision-making. This should focus on the relative contributions of both mothers and maternity care professionals in clinical decision making, and the potential implications of these choices.

The influence of ankle taping on changes in postural stability during soccer-specific activity.

CONTEXT: Postural stability diminishes with longer activity, which may increase the risk of injury. Tape can increase stability, but this effect diminishes after exercise. OBJECTIVE: To investigate the influence of ankle taping on postural stability during soccer-specific activity. PARTICIPANTS: 10 male, injury-free, semiprofessional soccer players. INTERVENTION: A 45-min treadmill protocol replicating the activity profile of soccer match play--with and without ankle tape. Postural stability was assessed every 7.5 min, requiring response to sudden ankle plantar flexion and inversion during single-leg stance. MAIN OUTCOME MEASURE: Reaction time to perturbation and center-of-gravity (CoG) displacement. RESULTS: Reaction time was significantly longer (P < .05) with longer exercise for both movements and conditions. No significant effect was evident in CoG displacement. For both outcome measures a nonsignificant benefit of taping was observed during the first 22.5 min of activity. CONCLUSION: Prolonged exposure to soccer-specific activity negates any beneficial effect of taping in improving postural stability.
