Coherent amplitude modulation of continuous-wave light in cesium vapor.

We report on observations of coherent, sustained oscillations in the absorption of continuous-wave light at 388 nm that excites the 6S1/2 → 8P3/2 transition in cesium (Cs) vapor. The oscillation frequency is close to the spacing of hyperfine levels of the 8P3/2 level that are excited simultaneously by the 388 nm field. We observe a threshold behavior of the oscillation amplitude with pump power and suggest that the effect is associated with infrared directional emission due to amplified spontaneous emission (ASE) from the 8P3/2 → 8S1/2 transition that is assisted by retro-reflections from cell windows. The effect may be used to probe a lasing process in an atomic vapor, by checking the temporal properties of the pump field transmitted through the vapor.

Patient Impression of Improvement 1 year After Sacrospinous Hysteropexy Versus Vaginal Hysterectomy in Women with Pelvic Organ Prolapse Stage 2 or Higher.

INTRODUCTION AND HYPOTHESIS: Patient-reported outcomes are relevant outcomes in studies on pelvic organ prolapse (POP) surgery, as anatomical recurrence alone does not have a significant correlation with perceived improvement. In the present study, the patient's impression of improvement after 1 year is studied after vaginal hysterectomy (VH) versus sacrospinous hysteropexy (SSH) in large cohorts from daily clinical practice. We hypothesize that there is no difference between the groups. METHODS: This is a secondary analysis on prospectively collected data in a multicenter cohort of patients who underwent VH or SSH for symptomatic POP. All patients had a POP-Q stage ≥ 2 in at least one compartment at baseline and were treated with VH or SSH between 2002 and 2019. The primary outcome was the patient-reported score on the patient global impression of improvement index (PGI-I) 1 year after surgery. The secondary outcome was a composite outcome of surgical success, defined as the absence of recurrent POP beyond the hymen with bothersome bulge symptoms and/or repeat surgery. RESULTS: A total of 378 women (196 VH and 182 SSH) were included. The median score on the PGI-I did not differ between VH and SSH. At 1 year post-operatively, 77 women after VH (73%) and 77 women after SSH (75%) considered their condition (very) much improved (p = 0.86). There was no difference in composite outcome of surgical success (126 out of 137 women [92%] after VH, 118 out of 125 women [94%] after SSH; p = 0.44). CONCLUSIONS: Our study shows that there was no difference in the type of surgery, VH or SSH, with regard to the patient's impression of improvement 1 year postoperatively in a large cohort from daily clinical practice.

Patient's preference for sacrospinous hysteropexy or modified Manchester operation: A discrete choice experiment.

OBJECTIVE: To investigate women's preference for modified Manchester (MM) or sacrospinous hysteropexy (SH) as surgery for uterine prolapse. DESIGN: Labelled discrete choice experiment (DCE). SETTING: Eight Dutch hospitals. POPULATION: Women with uterine prolapse, eligible for primary surgery and preference for uterus preservation. METHODS: DCEs are attribute-based surveys. The two treatment options were labelled as MM and SH. Attributes in this survey were treatment success ( levels SH: 84%, 89%, 94%; levels MM: 89%, 93%, 96%), dyspareunia (levels: 0%, 5%, 10%), cervical stenosis (levels: 1%, 6%, 11%) and severe buttock pain (levels: 0%, 1%). A different combination of attribute levels was used in each choice set. Women completed nine choice sets, making a choice based on attribute levels. Data were analysed in multinomial logit models. MAIN OUTCOME MEASURES: Women's preference for MM or SH. RESULTS: 137 DCEs were completed (1233 choice sets). SH was chosen in 49% of the choice sets, MM in 51%. Of all women, 39 (28%) always chose the same surgery. After exclusion of this group, 882 choice sets were analysed, in which women preferred MM, likely associated with a labelling effect, i.e. description of the procedure, rather than the tested attributes. In that group, MM was chosen in 53% of the choice sets and SH in 47%. When choosing MM, next to the label, dyspareunia was relevant for decision-making. For SH, all attributes were relevant for decision-making. CONCLUSIONS: The preference of women for MM or SH seems almost equally divided. The variety in preference supports the importance of individualised healthcare.

Location and motion of vaginal pessaries in situ in women with successful and unsuccessful pessary treatment for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: The objective was to compare the location and motion of pessaries between women with pelvic organ prolapse (POP) with a successful (fitting) and unsuccessful (non-fitting) pessary treatment on dynamic magnetic resonance imaging (dMRI). METHODS: A cross-sectional exploratory study of 15 women who underwent a mid-sagittal dMRI of the pelvic floor at rest, during contraction and during Valsalva with three different types of pessaries. The coordinates of the pessaries cross section, inferior pubic point (IPP) and sacrococcygeal junction (SCJ) were obtained and the location (position, orientation) and the motion (translation and rotation) were calculated. Differences between the groups and between the pessaries within the groups were compared. RESULTS: Nine women with a fitting pessary and 6 women with a non-fitting pessary were selected. In the non-fitting group, the pessaries were positioned more caudally and rotated more in clockwise direction and descended more, but not significantly, during Valsalva compared with the fitting group. The Falk pessary was positioned more anteriorly in the fitting group and more cranially in the non-fitting group compared with the ring and ring with support pessary. CONCLUSIONS: A non-fitting pessary was positioned more caudally at rest; on Valsalva, it rotated more clockwise and moved more caudally, suggesting that the dynamic characteristics of the pessary might play an important role in its effectiveness. Findings of this study serve as a basis for the development of new pessary designs.

Does three-dimensional anatomy improve student understanding?

We aim to provide an overview of the various digital three-dimensional visualizations used for learning anatomy and to assess whether these improve medical students' understanding of anatomy compared to traditional learning methods. Furthermore, we evaluate the attitudes of the users of three-dimensional visualizations. We included articles that compared advanced newer three-dimensional anatomy visualization methods (i.e., virtual reality, augmented reality, and computer-based three-dimensional visualizations) to traditional methods that have been used for a long time (i.e., cadaver and textbooks) with regard to users' understanding of anatomy. Of the 1,148 articles identified, 21 articles reported data on the effectiveness of using three-dimensional visualization methods compared to two-dimensional methods. Twelve articles found that three-dimensional visualization is a significantly more effective learning method compared to traditional methods, whereas nine articles did not find that three-dimensional visualization was a significantly more effective method. In general, based on these articles, medical students prefer to use three-dimensional visualizations to learn anatomy. In most of the articles, using three-dimensional visualization was shown to be a more effective method to gain anatomical knowledge compared to traditional methods. Besides that, students are motivated and interested in using these new visualization methods for learning anatomical structures. Clin. Anat. 32:25-33, 2019. © 2019 Wiley Periodicals, Inc.

Betulinic acid inhibits high-fat diet-induced obesity and improves energy balance by activating AMPK.

BACKGROUND AND AIM: Metabolic syndromes are prevalent worldwide and result in various complications including obesity, cardiovascular disease and type II diabetes. Betulinic acid (BA) is a naturally occurring triterpenoid that has anti-inflammatory properties. We hypothesized that treatment with BA may result in decreased body weight gain, adiposity and hepatic steatosis in a diet-induced mouse model of obesity. METHODS AND RESULTS: Mice fed a high-fat diet and treated with BA showed less weight gain and tissue adiposity without any change in calorie intake. Gene expression profiling of mouse tissues and cell lines revealed that BA treatment increased expression of lipid oxidative genes and decreased that of lipogenesis-related genes. This modulation was mediated by increased AMP-activated protein kinase (AMPK) phosphorylation, which facilitates energy expenditure, lipid oxidation and thermogenic capacity and exerts protective effects against obesity and nonalcoholic fatty liver disease. Overall, BA markedly inhibited the development of obesity and nonalcoholic fatty liver disease in mice fed a high-fat diet, and AMPK activation in various tissues and enhanced thermogenesis are two possible mechanisms underlying the antiobesity and antisteatogenic effects of BA. CONCLUSIONS: The current findings suggest that treatment with BA is a potential dietary strategy for preventing obesity and nonalcoholic fatty liver disease.

Recurrence risk is associated with preoperatively advanced prolapse stage: Is there a difference between women with stage 2 and those with stage 3 or 4 cystocele?

INTRODUCTION AND HYPOTHESIS: Pelvic organ prolapse (POP) recurrence after surgery is a major problem. POP that is more advanced preoperatively is associated with a higher risk of recurrence postoperatively. We hypothesized that women with a stage 2 cystocele differ from those with a stage 3 or 4 cystocele. The aim of this study was to compare the baseline characteristics of women with mild and those with more advanced cystocele. METHODS: Patients had participated in one of two multicenter prospective cohort studies on women undergoing conventional anterior colporrhaphy without previous POP surgery. This was a secondary analysis of these data. Women with a preoperative cystocele stage 2 were compared with women with a stage 3 or 4 cystocele. Logistic regression models were employed to calculate odds ratios (OR) and 95% confidence intervals (CI). RESULTS: Two hundred and sixty-nine women were assessed, of whom 132 (49.1%) had an advanced cystocele. Only older age was significantly associated with advanced cystocele preoperatively, with an OR of 1.07 (95% CI 1.04-1.10). There were no significant differences between women with advanced or stage 2 cystocele in body mass index, vaginal deliveries, assisted delivery, positive family history of POP, concurrent rectocele, concurrent uterine of vaginal vault prolapse, major levator ani muscle defects, or levator hiatal area. CONCLUSIONS: Women with advanced cystocele were significantly older than women with stage 2 cystocele. This raises the question whether it would be favorable to perform POP surgery in an earlier stage, i.e., at a younger age, in order to prevent POP recurrence.

Evaluation of treatment pattern and symptom control in patients with gastroesophageal reflux disease: multihospital questionnaire survey on the current situation in Korea.

Proton pump inhibitors (PPIs) are the most effective treatment for gastroesophageal reflux disease (GERD); however, a considerable number of patients fail to respond to PPI therapy and complain of nocturnal heartburn and sleep disturbance. The aims of this study are to evaluate the treatment pattern of GERD-related medications and their efficacy in relieving nocturnal heartburn. A total of 334 patients with GERD receiving PPI therapy within 6 months were enrolled in a multihospital questionnaire survey from January, 2014 to March, 2015. GERD symptoms and patients' satisfaction were assessed by patient questionnaires, and treatment patterns of GERD-related medications were assessed by investigators. Among the 334 patients, 95.8% used PPI once daily and 58.6% used a half-dose of PPI. The PPI treatment pattern was changed in 26.6% of all patients, of those, 54% of the patients doubled the PPI dose, and 29.2% of the patients switched to another PPI. Approximately 60.3% of all patients were prescribed more than three GERD-related medications. The overall satisfaction rate was 61.8%, and 32.2% of patients experienced nocturnal heartburn and sleep disturbance. In the extended-release PPI group, there were fewer nocturnal symptoms compared with the conventional PPI group (10% vs. 33.7%, respectively, P = 0.027). The use of more than three medications was inversely associated with patients' satisfaction (OR = 0.355, 95% CI; 0.197-0.642, P = 0.001). Most patients were prescribed adjunctive medications other than PPIs; however, patients' satisfaction was inversely associated with multiple drugs. Patients' satisfaction was superior in extended-release PPIs than conventional PPIs for the relief of nocturnal heartburn in Korean patients.

Genome-wide expression analysis of a rice mutant line under salt stress.

Salinity is a major environmental stress to plants. In this study, the ability of plants to tolerate salt was investigated by studying growth, physiological characteristics, and expression levels of genes related to the salt-stress response in the salt-tolerant rice mutant (Till-II-877), which was derived from γ-ray irradiation. Compared to plants grown under normal conditions, the height and root length of wild type (WT) were reduced by approximately 40 and 29% following exposure to salt stress for 3 weeks, whereas Till-II-877 line showed 29 and 23% reductions in plant height and root length, respectively. No significant changes were observed in total chlorophyll content, and the malondialdehyde content of the mutant increased less than that of the WT under salt treatment. Gene expression was compared between the WT and mutant lines using microarray analysis. An unbiased analysis of the gene expression datasets allowed us to identify the pathways involved in salt-stress responses. Among the most significantly affected pathways, changes in gene expression were observed in α-linolenic acid and linoleic acid metabolism (in lipid metabolism), fructose and mannose metabolism and glycolysis-gluconeogenesis (in carbohydrate metabolism), cysteine and methionine metabolism (in amino acid metabolism), and carbon fixation (in the energy metabolism of photosynthetic organisms) under salt stress. These results show that the differential response of plants subjected to salt stress was due to changes in multiple metabolic pathways. These findings increase our understanding of the effects of salt stress in rice and may aid in the development of salt-tolerant rice cultivars.

Comparative genomic hybridization analysis of rice dwarf mutants induced by gamma irradiation.

Comparative genomic hybridization (CGH) is a powerful tool used to analyze changes in copy number, polymorphisms, and structural variations in the genome. Gene copy number variation (CNV) is a common form of natural diversity in the genome, which can create new genes and alter gene structure. Thus, CNVs may influence phenotypic variation and gene expression. In this study, to detect CNVs, we irradiated rice seeds with gamma rays (300 Gy) and selected two dwarf mutagenized plants, GA-III-189 and -1052, in the M3 generation. These plants were subjected to CGH analysis using Agilent's RICE CGH array. Most of the CNVs identified were less than 10 kb in length. We detected 90 amplified and 18 deleted regions in GA-III-189, and 99 amplified and 11 deleted regions in GA-III-1052. Of note, CNVs were located on chromosome 12 in both GA-III-189 and -1052, which contained 39 commonly amplified regions in 29 genes. The commonly amplified genes included six genes encoding F-box domain-containing proteins. Alterations in these F-box domain-containing genes were confirmed by quantitative RT-PCR. Integration of CGH and gene expression data identified copy number aberrations and novel genes potentially involved in the dwarf phenotype. These CGH and gene expression data may be useful for uncovering the mechanisms underlying the dwarf phenotype.

Development of a transposon-based marker system for mutation breeding in sorghum (Sorghum bicolor L.).

Under certain circumstances, transposable elements (TE) can create or reverse mutations and alter the genome size of a cell. Sorghum (Sorghum bicolor L.) is promising for plant transposon tagging due to its small genome size and its low content of repetitive DNA. We developed a marker system based on targeted region amplification polymorphisms (TE-TRAP) that uses the terminal inverted repeats (TIRs) of transposons. A total of 3816 class 2 transposons belonging to the PIF/Harbinger family were identified from the whole sorghum genome that produced five primers, including eight types of TIRs. To define the applicability and utilization of TE-TRAP, we used 21 individuals that had been bred after ɤ-ray irradiation. In total, 31 TE-TRAP, 16 TD, and 21 AFLP primer combinations generated 1133, 223, and 555 amplicons, respectively. The percent polymorphic marker was 62.8, 51.1, and 59.3% for the TE-TRAP, TD, and AFLP markers, respectively. Phylogenetic and principal component analyses revealed that TE-TRAP divided the 21 individuals into three groups. Analysis of molecular variance suggested that TE-TRAP had a higher level of genetic diversity than the other two marker systems. After verifying the efficiency of TE-TRAP, 189 sorghum individuals were used to investigate the associations between the markers and the ɤ-ray doses. Two significant associations were found among the polymorphic markers. This TE-based method provides a useful marker resource for mutation breeding research.

Factors related to number of present teeth in Korean elderly adults aged 55-84 years.

OBJECTIVES: The aim of this study was to determine the associations between the number of present teeth (NT) and socio-economic, demographic and oral health behavioural factors among Korean adults aged 55-84 years. METHODS: The total subjects comprised 3767 individuals who were examined and who answered the questions on socio-economic status and oral health behaviour from the fourth Korean National Health and Nutrition Examination Survey conducted from 2007 to 2009. The dependent variable was NT, with binary status divided by the median. Socio-economic and demographic factors included gender, educational level, parent's educational levels, region of residence, household income, type of health insurance and mother's economic activity. Oral health behaviours were as follows: daily toothbrushing frequency, smoking status, recent dental visit and illegal dental treatment. Multivariate logistic regression models were applied to explain the associations between NT and other variables. RESULTS: In a model adjusted by socio-economic, demographic and oral health behavioural variables, subjects who lived in urban areas were more likely to have larger NT compared to those in suburban areas (OR: 1.22, P = 0.025). Males were more likely to have larger NT (OR: 1.90, P < 0.001), and daily toothbrushing frequency was associated with NT (OR = 1.25, P = 0.023). Non-smokers (OR: 2.44, P < 0.001) and past smokers (OR: 1.70, P < 0.001) were more likely to have lager NT compared to current smokers. Subjects without illegal dental treatments were more likely to have lager NT compared to those with illegal dental treatments (OR = 2.21, P < 0.001). CONCLUSIONS: Interventions aiming to preserve present teeth in elderly adults should consider socio-economic, demographic and oral health behavioural factors.

Comparison of RECIST 1.0 and RECIST 1.1 on computed tomography in patients with metastatic colorectal cancer.

OBJECTIVE: We conducted this study to compare tumor measurement by computed tomography (CT) and tumor response assessment between Response Evaluation Criteria In Solid Tumors (RECIST) 1.0 and RECIST 1.1 in patients with metastatic colorectal cancer (CRC). METHODS: We reviewed the medical records of patients with metastatic CRC who received first-line chemotherapy between January 2004 and December 2012 and compared CT tumor measurement using two RECIST versions. RESULTS: A total of 58 patients who had target lesions according to RECIST 1.0 were included in the study. The number of target lesions recorded by RECIST 1.1 was significantly lower than that by RECIST 1.0, with a decrease experienced in 48 patients (82.7%). Six patients had no target lesions because of the new criteria of RECIST 1.1 for lymph node size. Out of 95 lymph nodes from 58 patients, only 40% were defined as target lesions according to RECIST 1.1. The overall response rate of first-line chemotherapy according to RECIST 1.0 and 1.1 was 41.5 and 40.4%, respectively. The best tumor responses showed almost perfect agreement between RECIST 1.1 and RECIST 1.0 (ĸ = 0.913). Three patients showed disagreement of the best responses between the two RECIST versions. CONCLUSION: RECIST 1.1 showed a highly concordant response assessment with RECIST 1.0 in metastatic CRC and its clinical impact on therapeutic decisions was minimal.

Differences in the risk factors of reflux esophagitis according to age in Korea.

The prevalence of gastroesophageal reflux disease in Korea has been believed to be low, but the incidence of gastroesophageal reflux disease in Korea is expected to increase because of the longer life expectancy and more ingestion of westernized food. The aim of this study was to report differences in the risk factors of reflux esophagitis (RE) according to age in Korea. We prospectively recruited the subjects who had RE among those who visited a health promotion center for upper gastrointestinal cancer surveillance at Hallym Medical Center (five institutions) between January 2008 and February 2009. The enrolled study participants comprised 742 subjects with RE and 1484 healthy controls. The independent risk factors of RE in young and adult group were male sex, smoking, coffee, body mass index ≥ 25, hiatal hernia, and Helicobacter pylori negativity. The risk factors of RE in elderly group were smoking, coffee, and hiatal hernia. The risk factors for RE according to age group were found to differ. In elderly group, Helicobacter pylori infection was not a significant protective factor contrary to young and adult groups.

Genetic characterization of hatchery populations of Korean spotted sea bass (Lateolabrax maculatus) using multiplex polymerase chain reaction assays.

The spotted sea bass, Lateolabrax maculatus, is an important commercial and recreational fishery resource in Korea. Aquacultural production of this species has increased because of recent resource declines, growing consumption, and ongoing government-operated stock release programs. Therefore, the genetic characterization of hatchery populations is necessary to maintain the genetic diversity of this species and to develop more effective aquaculture practices. In this study, the genetic diversity and structure of three cultured populations in Korea were assessed using multiplex assays with 12 highly polymorphic microsatellite loci; 144 alleles were identified. The number of alleles per locus ranged from 6 to 28, with an average of 13.1. The mean observed and expected heterozygosities were 0.724 and 0.753, respectively. Low levels of inbreeding were detected according to the inbreeding coefficient (mean FIS = 0.003-0.073). All hatchery populations were significantly differentiated from each other (overall fixation index (FST) = 0.027, P < 0.01), and no population formed a separate cluster. Pairwise multilocus FST tests, estimates of genetic distance, mantel test, and principal component analyses did not show a consistent relationship between geographic and genetic distances. These results could reflect the exchange of breeds and eggs between hatcheries and/or genetic drift due to intensive breeding practices. For optimal resource management, the genetic variation of hatchery stocks should be monitored and inbreeding controlled within the spotted sea bass stocks that are being released every year. This genetic information will be useful for the management of both L. maculatus fisheries and the aquaculture industry.

Development and characterization of mouse monoclonal antibodies reactive with chicken IL-1ß.

Interleukin-1ß proteins from chicken, duck, goose, turkey, and pigeon share 77 to 99% amino acid sequence similarity among themselves, and only 31 to 35% sequence similarity is shared between avian and mammalian IL-1ß. There have been no antibodies that specifically detect avian IL-1ß, and the current study was conducted to develop mouse monoclonal antibodies (mAb) against chicken IL-1ß (chIL-1ß) to further define its biochemical and immunological properties. In this study, 2 mouse mAb that are specific for chIL-1ß were produced and characterized. Both mAb identified a 66.0 kDa recombinant chIL-1ß protein expressed in Escherichia coli by Western blot analysis that corresponded to the expected molecular weight of a recombinant fusion protein containing the full-length 23.0 kDa chIL-1ß protein and a 43.0 kDa maltose binding protein tag. Immunohistochemical analysis identified cells producing endogenous chIL-1ß in the cecal tonsils, bursa of Fabricius, and spleen. Purified recombinant chIL-1ß dose-dependently stimulated the proliferation and nitric oxide production by thymocytes, and both activities were inhibited by co-incubation with the 2 chIL-1ß mAb described in this paper. These mAb will be important immune reagents for basic and applied poultry research of IL-1ß in poultry.

Effects of in ovo injection with selenium on immune and antioxidant responses during experimental necrotic enteritis in broiler chickens.

This study was conducted to investigate the effects of in ovo injection of Se on modulating the immune system and antioxidant responses in broiler chickens with experimental necrotic enteritis. Broiler eggs were injected at 18 d of embryo age with either 100 µL of PBS alone or sodium selenite (Na2SeO3) in PBS, providing 0 (SS0), 10 (SS10), or 20 (SS20) µg of Se/egg. At 14 d posthatch, PBS-treated and uninfected chickens were kept as the control group, whereas the remaining chickens were orally infected with 1.0 × 10(4) sporulated oocysts of Eimeria maxima (SS0, SS10, SS20). At 18 d posthatch, E. maxima-infected chickens were orally infected with 1.0 × 10(9) cfu of Clostridium perfringens. Infected control SS0 group showed significantly decreased BW compared with the uninfected control. However, SS20 group showed significantly increased BW compared with the infected control SS0 group, whereas the BW were similar among uninfected control and infected SS10 and SS20 groups. The SS10 group showed significantly lower intestinal lesions compared with the SS0 group, and oocyst production was decreased in both SS10 and SS20 groups. Serum malondialdehyde level and catalase activity were also decreased in both SS10 and SS20 groups, whereas the superoxide dismutase level was significantly lower in the SS10 group compared with the SS0 group. The SS20 group showed significantly higher levels of transcripts for IL-1ß and IL-6 in intestine, and SS10 and SS20 groups had higher levels of transcripts for IL-8 and inducible nitric oxide synthase expression and decreased glutathione peroxidase 7 mRNA levels compared with the SS0 group. The SS10 and SS20 groups also showed increased serum antibody levels to C. perfringens α-toxin and NetB toxin compared with the SS0 group. These collective results suggest that the injection of Se into the amniotic cavity of developing eggs may be beneficial for enhancing immune and antioxidant responses in the hatched chickens exposed to the necrotic enteritis-causing pathogens.

Laparoscopic Davydov vs. laparoscopic Vecchietti neovaginoplasty in women with Mayer-Rokitansky-Küster-Hauser syndrome; a systematic review and meta-analysis.

OBJECTIVE: To summarize the available evidence on the laparoscopic Davydov and Vecchietti methods to create a neovagina and to compare these techniques with a focus on neovaginal length, sexual function, operative time, and complications. DESIGN: A systematic electronic search up to August 2022 using PubMed and Embase is performed. SETTING: Not applicable. PATIENTS: Women with Mayer-Rokistansky-Küster-Hauser syndrome. INTERVENTIONS: All published clinical studies concerning the laparoscopic Davydov and laparoscopic Vecchietti procedures as a surgical technique to create a neovagina in women with Mayer-Rokistansky-Küster-Hauser syndrome were obtained. The guidelines for the preferred reporting items for systematic reviews and meta-analysis were followed. The following data were extracted: operative time, hospital stay, major early complications (within 3 months postsurgery), dilation therapy, neovaginal length, vaginal discharge, vaginal stenosis, time to sexual activity, sexual satisfaction, penetrative sexual activity, dyspareunia, score on the Female Sexual Function Index (FSFI), and duration of follow-up. The Newcastle Ottawa Scale was used to assess the quality of articles. MAIN OUTCOME MEASURES: Neovaginal length, FSFI scores, operative time, and complications. RESULTS: A total of 1,163 articles were identified, of which 33 studies were included in this systematic review. Of these, 12 studies (380 patients) are related to the Davydov method, 19 studies (1,126 patients) to the Vecchietti method, and 2 articles concern both. There is clinical heterogeneity and variety in the quality of the studies. Eighteen studies were included in the meta-analyses. The mean neovaginal length 12 months after the Davydov method is 8.3 cm (95% confidence interval [CI] 8.1-8.6), vs. 8.7 cm (95% CI 7.2-10.3) after the Vecchietti method. The mean FSFI score after the Davydov method is 28.9 (95% CI 26.8-31.1), compared with 27.5 (95% CI 25.0-30.1) after the Vecchietti method. The operative time of the Davydov method is 126 minutes (95% CI 109-143), compared with 40 minutes (95% CI 35-45) of the Vecchietti method. CONCLUSIONS: The operations yield comparable neovaginal length, sexual function, and complication rates. The mean FSFI scores indicate no sexual dysfunction in either group. The operative time of the Davydov method is significantly longer. There is no superiority shown for one of the surgical techniques in functional terms.

Lessons learned from the experiences of patients with chronic pelvic pain syndrome (CPP syndrome) with a multidisciplinary consultation: a qualitative study.

INTRODUCTION: Chronic pelvic pain syndrome is a complex multifactorial condition with an increasing prevalence probably due to a rising awareness. Chronic pelvic pain syndrome is pain in the pelvic area and often accompanied with complaints in other organ systems of the lesser pelvis. Patients with chronic pelvic pain syndrome who present at our center are evaluated in a standardized care pathway with an integrated multidisciplinary consultation. The team works in a single center and consists of gynecologists, pain specialists, urologists, a pelvic floor physiotherapist and a psychologist. The aim of this interview study is to evaluate the value of the multidisciplinary consultation from the patient's perspectives. METHODS: In a qualitative study, we evaluated the experiences and perspectives of patients with chronic pelvic pain syndrome concerning the multidisciplinary consultation at the Radboud University Medical Center. Semistructured interviews were conducted with patients with chronic pelvic pain syndrome who attended a multidisciplinary consultation between 2019 and 2022. All interviews were transcribed verbatim, coded and analyzed via ATLAS.ti with the conventional content analysis. RESULTS: Data saturation was reached after seven interviews, followed by three confirmative interviews. In total, 10 patients (22-76 years) participated in the study. Three relevant themes were identified in the interviews: the deleterious effects of pain on overall health, the importance of the design of the multidisciplinary consultation, and the performance of healthcare professionals (knowledge, skills and interaction with patients and colleagues). Participants suggested that although the consultation did not improve their pain experience, there was value in having a comprehensive assessment of their disease. Patients preferred the consultation to occur at the beginning of the care. Additionally, they acknowledged the performance of healthcare providers and having their complaints recognized. However, some participants suggested the need for additional attention to mental health issues during the multidisciplinary consultation. DISCUSSION: Even though patients did not perceive the multidisciplinary consultation to improve their pain experience, they appreciated the sense of recognition by this team. CONCLUSION: A multidisciplinary consultation is of value from the patients' perspective. A suggestion for improvement emerged where the multidisciplinary consultation should occur at the beginning of the patient journey.
