RESUMO
(1) Background: Pelvic organ prolapse (POP) affects millions of women globally, impacting their quality of life and potentially influencing family planning decisions. This study aimed to assess the impact of uterus-preserving prolapse surgery on the sexual function, desire for children, and pregnancy outcomes in premenopausal women with symptomatic POP. (2) Methods: A survey study was conducted among patients who underwent sacrospinous hysteropexy at a tertiary hospital between 2001 and 2021. Telephone interviews were performed to gather data on sexual function, desire for children, and satisfaction with surgical outcomes. (3) Results: The study included 33 premenopausal women, revealing diverse factors influencing sexual activity and desire for children following surgery. While most of the participants expressed a desire for children after surgery, sexually inactive individuals were more likely to report an unfulfilled desire for children. Fear of incontinence during sexual activity emerged as a significant concern for the sexually inactive participants. (4) Conclusions: The study highlights the need for comprehensive counselling and tailored interventions to address the multifaceted needs of women with POP. Further research is warranted to highlight the long-term implications of uterus-preserving surgeries on women's health and well-being.
RESUMO
The regulation of thymocyte development by RNA-binding proteins (RBPs) is largely unexplored. We identify 642 RBPs in the thymus and focus on Arpp21, which shows selective and dynamic expression in early thymocytes. Arpp21 is downregulated in response to T cell receptor (TCR) and Ca2+ signals. Downregulation requires Stim1/Stim2 and CaMK4 expression and involves Arpp21 protein phosphorylation, polyubiquitination and proteasomal degradation. Arpp21 directly binds RNA through its R3H domain, with a preference for uridine-rich motifs, promoting the expression of target mRNAs. Analysis of the Arpp21-bound transcriptome reveals strong interactions with the Rag1 3'-UTR. Arpp21-deficient thymocytes show reduced Rag1 expression, delayed TCR rearrangement and a less diverse TCR repertoire. This phenotype is recapitulated in Rag1 3'-UTR mutant mice harboring a deletion of the Arpp21 response region. These findings show how thymocyte-specific Arpp21 promotes Rag1 expression to enable TCR repertoire diversity until signals from the TCR terminate Arpp21 and Rag1 activities.

IMPORTANCE: There are still doubts about long-term satisfaction rates of native tissue uterine preserving surgical techniques for pelvic organ prolapse. OBJECTIVE: The objective of this study was to compare long-term subjective success rates and satisfaction rates between vaginal sacrospinous hysteropexy (SSHP) and vaginal hysterectomy with uterosacral ligament suspension (VH-USLS). STUDY DESIGN: This was a retrospective single-center, observational matched cohort study in women receiving either SSHP or VH-USLS between 2004 and 2021. Primary outcome was overall subjective success (combined outcome of absence of bulge nor retreatment, and satisfaction with operation) at least 12 months after surgery. Satisfaction with the operation was defined as a combined Patient Global Impression of Improvement rating ≤ 2 and a patient satisfaction score ≥7. RESULTS: Of 583 patients, 192 patients could be matched (SSHP, 96; VH-USLS, 96), with 55% (SSHP, 60; VH-USLS, 45) participating at the telephone interview. Mean follow-up time was 77 months for VH-USLS, and 36 months for SSHP, respectively. No difference in overall subjective success rates was found between the groups (45% VH-USLS and 51% SSHP; P = 0.54). Overall satisfaction was similar between both groups (70% vs 71%, P = 0.90). Logistic regression found no influence of duration of follow-up and the overall subjective success rate. Both procedures would be recommended to a relative or friend by a large majority of patients (88% vs 85%, P = 0.761). Operative time and hospitalization time were significantly shorter in the SSHP group. No serious complications were reported. CONCLUSIONS: Overall success rates did not differ between both procedures after at least 1 year of follow-up with relatively high satisfaction rates. Sacrospinous hysteropexy had shorter operative time and shorter duration of hospitalization.

Conventional antiviral memory CD4 T cells typically arise during the first two weeks of acute infection. Unlike most viruses, cytomegalovirus (CMV) exhibits an extended persistent replication phase followed by lifelong latency accompanied with some gene expression. We show that during mouse CMV (MCMV) infection, CD4 T cells recognizing an epitope derived from the viral M09 protein only develop after conventional memory T cells have already peaked and contracted. Ablating these CD4 T cells by mutating the M09 genomic epitope in the MCMV Smith strain, or inducing them by introducing the epitope into the K181 strain, resulted in delayed or enhanced control of viral persistence, respectively. These cells were shown to be unique compared to their conventional memory counterparts; producing higher IFNγ and IL-2 and lower IL-10 levels. RNAseq analyses revealed them to express distinct subsets of effector genes as compared to classical CD4 T cells. Additionally, when M09 cells were induced by epitope vaccination they significantly enhanced protection when compared to conventional CD4 T cells alone. These data show that late-rising CD4 T cells are a unique memory subset with excellent protective capacities that display a development program strongly differing from the majority of memory T cells.

Like all herpesviruses, cytomegaloviruses (CMVs) code for many immunomodulatory proteins including chemokines. The human cytomegalovirus (HCMV) CC chemokine pUL128 has a dual role in the infection cycle. On one hand, it forms the pentameric receptor-binding complex gHgLpUL(128,130,131A), which is crucial for the broad cell tropism of HCMV. On the other hand, it is an active chemokine that attracts leukocytes and shapes their activation. All animal CMVs studied so far have functionally homologous CC chemokines. In murine cytomegalovirus (MCMV), the CC chemokine is encoded by the m131/m129 reading frames. The MCMV CC chemokine is called MCK2 and forms a trimeric gHgLMCK2 entry complex. Here, we have generated MCK2 mutant viruses either unable to form gHgLMCK2 complexes, lacking the chemokine function or lacking both functions. By using these viruses, we could demonstrate that gHgLMCK2-dependent entry and MCK2 chemokine activity are independent functions of MCK2 in vitro and in vivo. The gHgLMCK2 complex promotes the tropism for leukocytes like macrophages and dendritic cells and secures high titers in salivary glands in MCMV-infected mice independent of the chemokine activity of MCK2. In contrast, reduced early antiviral T cell responses in MCMV-infected mice are dependent on MCK2 being an active chemokine and do not require the formation of gHgLMCK2 complexes. High levels of CCL2 and IFN-γ in spleens of infected mice and MCMV virulence depend on both, the formation of gHgLMCK2 complexes and the MCK2 chemokine activity. Thus, independent and concerted functions of MCK2 serving as chemokine and part of a gHgL entry complex shape antiviral immunity and virus dissemination.

Infections in early life can elicit substantially different immune responses and pathogenesis than infections in adulthood. Here, we investigate the consequences of murine cytomegalovirus infection in newborn mice on NK cells. We show that infection severely compromised NK cell maturation and functionality in newborns. This effect was not due to compromised virus control. Inflammatory responses to infection dysregulated the expression of major transcription factors governing NK cell fate, such as Eomes, resulting in impaired NK cell function. Most prominently, NK cells from perinatally infected mice have a diminished ability to produce IFN-γ due to the downregulation of long non-coding RNA Ifng-as1 expression. Moreover, the bone marrow's capacity to efficiently generate new NK cells is reduced, explaining the prolonged negative effects of perinatal infection on NK cells. This study demonstrates that viral infections in early life can profoundly impact NK cell biology, including long-lasting impairment in NK cell functionality.

PURPOSE OF THE RESEARCH: Vaginal pessary use is an established, non-surgical treatment option for pelvic organ prolapse. While satisfaction rates are initially high, they seem to decline over time. We aimed to determine the median duration of pessary use among our patients and to evaluate reasons for discontinuation. METHODS: All patients who were treated with a vaginal pessary for pelvic organ prolapse between 2007 and 2022 at our institution (a maximum observation period of 15 years) were included in this retrospective cohort study. Data were collected from the in-house electronic databases and the date of pelvic floor surgery was defined as the primary endpoint. In case of no documented surgery, the date of the last follow-up visit (for patients lost to follow-up or who discontinued pessary use without subsequent surgery) or the date of final data collection (for those with presumed continued pessary use) was used as the primary endpoint. Duration of pessary use is represented by Kaplan-Meier curves. Effects of possible confounders were investigated by Cox regression models. A Cox regression model was evaluated for patients with the three most common types of pessary: ring, cube and shell. A chi-square test was performed to compare therapy adherence according to pessary type. PRINCIPAL RESULTS: Data of 779 patients could be included in the statistical analysis. The estimated median duration of pessary use was 173 weeks (95 % CI 104-473) - approximately 3.3 years. Overall, 30 % of patients opted for surgical therapy and the majority of them did so within 4 months of initiation of pessary use (median time: 19 weeks, 95 % CI 16-26). In 5 % of cases a discontinuation of pessary use without subsequent surgery was documented and 18 % were lost to follow-up before a planned visit, thus leaving 47 % of our patients with presumed continued pessary use. Possible confounding factors for discontinuation of pessary use were tested but were found to be non-significant (body mass index, Pelvic Organ Prolapse - Quantification score, pelvic floor training, age, parity, menopausal status, nicotine consumption, incontinence or size of pessary). Reasons for discontinuation of pessary use were documented in 51 % of patients: unspecified patient wish (23 %), pessary use tiredness (10 %), general dissatisfaction with pessary therapy (7 %), unspecified reasons (5 %), pessary self-change not possible (1 %), erosion, bleeding, pain (2 %); none of the pessary types fitted (2 %). CONCLUSIONS: According to our data, almost half of our patients with pelvic organ prolapse and pessary therapy continued pessary use until a maximum follow-up time of 15 years, whereas about one-third of patients finally opted for surgical repair (a majority of these within 4 months after pessary therapy initiation). The remaining patients were either lost to follow-up or discontinued pessary use without subsequent surgery. The stated reasons for discontinuation of pessary use were mostly non-specific, but only 1 % reported that pessary self-change was not possible. Erosion bleeding or pain was documented in only 2 % of cases as reason for discontinuation. This information helps clinicians to inform their patients with pelvic organ prolapse about expected pessary therapy success and strengthens individual counselling. Furthermore, our data indicates vaginal pessary use for pelvic organ prolapse is feasible and safe for all women and that therapy adherence can extend beyond 5 years.

Murine gammaherpesvirus 68 (MHV-68), a widely used small-animal model for the analysis of gammaherpesvirus pathogenesis, encodes the MHV-68-specific ORFs M12 and M13. The function of M12 and M13 has not been investigated so far. Therefore, we constructed and analysed recombinant MHV-68 with mutations in either M12, M13 or M12/M13. Both the M12 and M13 mutants did not display any phenotype in vitro or in vivo. However, although the M12/13 double mutant showed similar lytic growth in fibroblasts in vitro and in the lungs of infected mice as wild-type MHV-68, it was significantly attenuated in vivo during latency. This phenotype was completely restored in a revertant of the M12/13 double mutant. Thus, it appears that M12 and M13 might have redundant functions that are only revealed if both genes are lacking. The observation that M12/13 have a function during latency not only contributes to the further understanding of the pathogenesis of MHV-68 infection but might also be of interest considering that M12/13 are located at a genomic position similar to that of LMP2A and K15. The latter are important proteins of their respective human gammaherpesviruses EBV and KSHV that contribute to cellular survival, cell activation and proliferation, which was deduced from in vitro studies.

BACKGROUND: Pelvic organ prolapse (POP) is a common health problem, with a high lifetime risk for prolapse surgery. Uterine-preserving procedures such as vaginal sacrospinous hysteropexy (SSH) have become an increasingly utilized surgical option for the primary treatment of POP. We wanted to evaluate peri- and postoperative outcome parameters of SSH as an alternative to vaginal hysterectomy with apical fixation. METHODS: A retrospective cohort study was conducted (2003-2021). All patients who underwent primary SSH (study group) for symptomatic POP were matched 1:1 by age and BMI with patients who underwent primary prolapse hysterectomy with apical fixation (control group). RESULTS: A total of 192 patients were included with 96 patients in the each of the SSH and hysterectomy groups. There were no statistically significant differences in baseline characteristics. The SSH group show a significantly shorter mean surgery time (p < 0.001), significantly fewer hospitalization days (p < 0.001), and significantly less intraoperative blood loss (p = 0.033) in comparison to the control group. Neither group had any intraoperative complication, or an intraoperative conversion to other surgical management options. No statistically significant difference was found in postoperative complications as categorized by the Clavien-Dindo classification or in postoperative urogynecological issues (UTI, de-novo, incontinence, residual urine, voiding disorders). Through log regression, none of the confounding factors such as age, BMI, or preoperative POP-Q stage could be identified as independent risk factors for the occurrence of postoperative complications. CONCLUSIONS: Our results confirm that a uterus-preserving technique has many benefits and, thus, should be considered as an additional intermediate step in a long-term treatment plan of pelvic organ prolapse.
RESUMO
INTRODUCTION AND HYPOTHESIS: Botulinum toxin (BoNT) is a widely used treatment for overactive bladder (OAB). Despite its common use, no standardized treatment regimen exists so far. The aim of this survey was to evaluate the variation in perioperative treatment strategies among members of the German-speaking urogynecologic societies. MATERIALS AND METHODS: A clinical practice online survey was carried out between May 2021 and May 2022, and all members of the German, Swiss, and Austrian urogynecologic societies were invited to participate. Participants were grouped in two ways. First, they were grouped into (1) urogynecologists with board certification and (2) non-board-certified general obstetricians and gynecologists (OBGYNs). Second, we set a cut-off at 20 transurethral BoNT procedures per year to differentiate between (1) high- and (2) low-volume surgeons. RESULTS: One hundred and six completed questionnaires were received. Our results demonstrated that BoNT is mostly used as a third-line treatment (93%, n = 98/106), while high-volume surgeons used it significantly more often as a first/second-line treatment (21% vs. 6%, p = 0.029). Large variations existed in the use of perioperative antibiotics, preferred sites of injection, the number of injections, and the timing of the measurement of the postvoid residual volume (PVRV). Forty percent of participants did not offer outpatient treatment to patients. Local anesthesia (LA) was mostly used by board-certified urogynecologists (49% vs. 10%, p < 0.001) and high-volume surgeons (58% vs. 27%, p = 0.002). Injections into the trigone were also more often performed by board-certified urogynecologists and high-volume surgeons (22% vs. 3% (p = 0.023) and 35% vs. 6% (p < 0.001), respectively). PVRV was controlled between weeks 1 and 4 by only 54% of participants (n = 57/106). Clean intermittent self-catheterization (CISC) was infrequently taught (26%). CONCLUSIONS: Our survey confirmed that BoNT is widely used by urogynecologists in the three German-speaking countries, but practice patterns vary widely, and no standardized method could be detected, despite interviewing urogynecologic experts. These results clearly demonstrate that there is a need for studies to define standardized treatment strategies for the best perioperative and surgical approach regarding the use of BoNT in patients with OAB.

RESUMO
BACKGROUND: Local estrogen therapy (LET) has beneficial effects on genitourinary atrophy; however it is currently unclear if LET improves sexual function in postmenopausal women with pelvic organ prolapse (POP). AIM: To evaluate if LET vs placebo results in an improved sexual function in postmenopausal women with symptomatic POP. METHODS: We performed a secondary analysis of sexual outcomes of a previous randomized controlled trial comparing LET and placebo in 120 postmenopausal women (60/group) with symptomatic POP stage ≥3 and planned prolapse surgery. Women were randomly assigned to receive local estrogen or placebo cream 6 weeks preoperatively. The effect of therapy vs placebo was assessed with ANOVA with interaction effect of time*group and a multivariable linear regression model was built to assess the impact of different variables on sexual function before therapy. OUTCOMES: We evaluated the sexual function score in sexually active women of our study population using the German Pelvic Floor Questionnaire at recruitment time and again after 6 weeks of treatment. RESULTS: Among 120 randomized women, 66 sexually active women remained for final analysis. There was no significant difference in the change of the sexual function score over time between the treatment groups (difference in changes in score from baseline to 6 weeks for Estrogen group vs control group was -0.110 with 95% CI -0.364 to 0.144) Multivariable analysis showed that no independent risk factor for unsatisfying sexual function score could be identified. CLINICAL IMPLICATIONS: Based on our results, LET has no beneficial effect on sexual function in postmenopausal women with POP. STRENGTHS AND LIMITATIONS: Main strength of our study lies in the study design and in the use of a condition- specific questionnaire. As this is a secondary analysis, this study may be insufficiently powered to identify differences in sexual data between groups. CONCLUSION: LET had no impact on female sexuality in postmenopausal women with POP. Marschalek M-L, Bodner K, Kimberger O, et al.

Broad tissue tropism of cytomegaloviruses (CMVs) is facilitated by different glycoprotein entry complexes, which are conserved between human CMV (HCMV) and murine CMV (MCMV). Among the wide array of cell types susceptible to the infection, mononuclear phagocytes (MNPs) play a unique role in the pathogenesis of the infection as they contribute both to the virus spread and immune control. CMVs have dedicated numerous genes for the efficient infection and evasion of macrophages and dendritic cells. In this study, we have characterized the properties and function of M116, a previously poorly described but highly transcribed MCMV gene region that encodes M116.1p, a novel protein necessary for the efficient infection of MNPs and viral spread in vivo. Our study further revealed that M116.1p shares similarities with its positional homologs in HCMV and RCMV, UL116 and R116, respectively, such as late kinetics of expression, N-glycosylation, localization to the virion assembly compartment, and interaction with gH-a member of the CMVs fusion complex. This study, therefore, expands our knowledge about virally encoded glycoproteins that play important roles in viral infectivity and tropism. IMPORTANCE Human cytomegalovirus (HCMV) is a species-specific herpesvirus that causes severe disease in immunocompromised individuals and immunologically immature neonates. Murine cytomegalovirus (MCMV) is biologically similar to HCMV, and it serves as a widely used model for studying the infection, pathogenesis, and immune responses to HCMV. In our previous work, we have identified the M116 ORF as one of the most extensively transcribed regions of the MCMV genome without an assigned function. This study shows that the M116 locus codes for a novel protein, M116.1p, which shares similarities with UL116 and R116 in HCMV and RCMV, respectively, and is required for the efficient infection of mononuclear phagocytes and virus spread in vivo. Furthermore, this study establishes the α-M116 monoclonal antibody and MCMV mutants lacking M116, generated in this work, as valuable tools for studying the role of macrophages and dendritic cells in limiting CMV infection following different MCMV administration routes.

OBJECTIVE: To define potential risk factors for recurrence of prolapse. METHODS: This short report included all women who presented with recurrence of prolapse as well as without any recurrence signs after a vaginal approach of native tissue prolapse repair at an urogynecological center in Austria. RESULTS: A total of 124 recurrence cases and 64 women with no signs of recurrence after their index prolapse surgery were included. Multivariate analysis identified advanced preoperative POPQ stage (pelvic organ prolapse-quantification) as an independent risk factor for postoperative recurrence of prolapse (pâ¯= 0.045). CONCLUSION: Initial proper preoperative counseling is of particular importance to modulate patients' expectations after prolapse surgery.

The aim of this prospective randomized, double-masked, placebo-controlled, multicenter study was to analyze the surgeon's individual assessment of tissue quality during pelvic floor surgery in postmenopausal women pre-treated with local estrogen therapy (LET) or placebo cream. Secondary outcomes included intraoperative and early postoperative course of the two study groups. Surgeons, blinded to patient's preoperative treatment, completed an 8-item questionnaire after each prolapse surgery to assess tissue quality as well as surgical conditions. Our hypothesis was that there is no significant difference in individual surgical assessment of tissue quality between local estrogen or placebo pre-treatment. Multivariate logistic regression analysis was performed to identify independent risk factors for intra- or early postoperative complications. Out of 120 randomized women, 103 (86%) remained for final analysis. Surgeons assessed the tissue quality similarity in cases with or without LET, representing no statistically significant differences concerning tissue perfusion, tissue atrophy, tissue consistency, difficulty of dissection and regular pelvic anatomy. Regarding pre-treatment, the rating of the surgeon correlated significantly with LET (r = 0.043), meaning a correct assumption of the surgeon. Operative time, intraoperative blood loss, occurrence of intraoperative complications, total length of stay, frequent use of analgesics and rate of readmission did not significantly differ between LET and placebo pre-treatment. The rate of defined postoperative complications and use of antibiotics was significantly more frequent in patients without LET (p = 0.045 and p = 0.003). Tissue quality was similarly assessed in cases with or without local estrogen pre-treatment, but it seems that LET prior to prolapse surgery may improve vaginal health as well as tissue-healing processes, protecting these patients from early postoperative complications.
RESUMO
To date there is no standardized regimen or evidence-based practical guideline concerning post-void residual (PVR) measurement after urogynecologic surgeries. This survey aimed to evaluate current practice patterns and the approach taken among urogynecologists surrounding PVR measurement. An online survey was sent to members of several urogynecologic societies assessing pre- and postoperative management of patients undergoing urogynecologic surgery. A total of 204 urogynecologists from 21 countries participated in the survey. The vast majority of urogynecologists perform some kind of voiding trial to assess voiding function postoperatively. The cut-off values to perform catheterization, the methods of measurement, and the number of successfully passed voiding showed strong differences. Only 34.4% of the respondents consider routine PVR measurement after urogynecologic surgery to be evidence-based. PVR measurement after urogynecologic surgeries is widely performed and if pathological, it almost always provokes invasive treatment. However, there is a wide variation of implemented strategies, methods, and cut-off values. Scientific societies are challenged to devise a standardized regimen based on evidence for the management of urinary retention after urogynecologic surgery.
RESUMO
Despite an estimated prevalence of 13% in women, the exact etiology of non-neurogenic overactive bladder syndrome is unclear. The aim of our study was to gain a better understanding of the pathophysiology of female overactive bladder syndrome by mapping the urinary proteomic profile. We collected urine samples of 20 patients with overactive bladder syndrome and of 20 controls. We used mass spectrometric analysis for label-free quantitation, Swissprot human database for data search, Scaffold for data allocation and the Reactome Knowledgebase for final pathway enrichment analysis. We identified 1897 proteins at a false discovery rate of 1% and significance level p < 0.001. Thirty-seven significant proteins of the case group and 53 of the control group met the criteria for further pathway analysis (p < 0.0003 and Log2 (fold change) >2). Significant proteins of the overactive bladder group were, according to the 25 most relevant pathways, mainly involved in cellular response to stress and apoptosis. In the control group, significant pathways mainly concerned immunological, microbial-protective processes and tissue- elasticity processes. These findings may suggest a loss of protective factors as well as increased cellular response to stress and apoptosis in overactive bladder syndrome.
RESUMO
The COVID-19 pandemic led to dramatical changes in elective medical care. We analysed its impact on patients with female pelvic floor dysfunction during the 6 weeks of lockdown in Austria. A cross-sectional study was conducted: All 99 women who presented at the urogynaecologic outpatient clinic of the Medical University of Vienna with pelvic organ prolapse (POP) or urinary incontinence (UI) from December 2019 up to the lockdown in March 2020 were included and contacted. 97% of these women (96 participants) agreed to participate in the survey conducted to asses pelvic floor related quality of life (QoL) through telephone- interrogation. The mean age was 59 ± 14.8 years, the POP group consisted of 42 women while the UI group included 54 women. Most participants (83% of POP and 81% of UI cases) stated that their female pelvic floor dysfunction had remained equally relevant or had become even more significant during the lockdown. Associated symptoms and psychological strain also maintained their relevance during the lockdown (UI: p = 0.229; POP: p = 0.234). Furthermore, 97% of all interviewed women indicated to be strongly willing to continue their treatment. A generalised linear model regression revealed no clinical or demographic risk factors for psychological strain during the lockdown (p > 0.05). Our results demonstrate that women's QoL remains significantly impaired by their pelvic-floor disorders even during a worldwide crisis such as COVID-19. Therefore, elective disciplines such as urogynaecology urgently require novel and innovative strategies for continued patient care even in times of a lockdown.
