We propose and study an iterative substructuring method for an $$h$$ - $$p$$ Nitsche-type discretization, following the original approach introduced in Bramble et al. Math. Comp. 47(175):103-134, () for conforming methods. We prove quasi-optimality with respect to the mesh size and the polynomial degree for the proposed preconditioner. Numerical experiments assess the performance of the preconditioner and verify the theory. [ABSTRACT FROM AUTHOR]

Australian aborigines were astute botanists. Their ability to find food, water, and medicinal plants in the harsh Australian desert is a testimony to their brilliance. Unfortunately, much of this traditional knowledge is disappearing along with their culture. Scientists are working to rediscover and preserve the rich medicinal knowledge found in aboriginal bush medicine 'down under.' [ABSTRACT FROM AUTHOR]

Background: Mild cognitive impairment in Parkinson's disease (PD-MCI) includes deficits in different cognitive domains, and one domain to explore for neurocognitive impairment following the DSM-V is social cognition. However, this domain is not included in current criteria for PD-MCI diagnosis. Moreover, tests vary across studies. It is, therefore, crucial to optimize cognitive assessment in PD-MCI. We aimed to do so by using Machine Learning., Methods: 275 PD patients were included. Four cognitive batteries were created: two Standard ones (Levels I and II), applying current criteria and "traditional" tests; two Alternative ones (Levels I and II), which incorporated a test of social cognition. These batteries were included in the Random Forest (RF) classifier. To assess RF performance, the AUC was considered, and the Variable Importance Index was estimated to understand the contribution of each test in PD-MCI classification., Results: Standard Level I and II showed an AUC of 0.852 and 0.892, while Alternative Level I and II showed an AUC of 0.898 and of 0.906. Variable Importance Index revealed that TMT B-A, Ekman test, RAVLT-IR, MoCA, and Action Naming were tests that most contributed to PD-MCI classification., Conclusion: The Alternative level I assessment demonstrated a similar classification capacity to the Standard level II assessment. This finding suggests that in the cognitive assessment of PD patients, it is crucial to consider the most affected cognitive domains in this clinical population, including social cognition. Taken together, these results suggest to revise current criteria for the diagnosis of PD-MCI., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Introduction and Hypothesis: The use of validated Quality of Life (QoL) questionnaires is useful in the standardization and interpretation process of pelvic floor patient symptoms, due to their functional nature and high prevalence. The Pelvic Floor Distress Inventory QoL questionnaire (PFDI-20) serves both as a symptom inventory and a measure of the degree of bother and distress caused by pelvic floor symptoms. It includes items related to pelvic organ prolapse and lower gastrointestinal and bladder dysfunction., Methods: After consensus translation and a comprehension test, the Italian version of the questionnaire was submitted to patients reporting bowel, bladder, or pelvic disorders (cases) and to asymptomatic women (controls). Cases received the questionnaire once again 2 weeks later by email., Results: A total of 254 patients answered the questionnaire. Construct validity was demonstrated by discriminating between cases and controls. Convergent validity was demonstrated for each domain (F < 0.001). In-ernal consistency reliability showed a satisfactory range (0.816-0.860)., Conclusions: The PFDI-20 allows a comprehensive assessment of the effect of pelvic floor disorders on the quality of life of women. Moreover, the PFDI-20 represents a very solid QoL tool, since it has been extensively used in literature, and its use is highly recommended by the International Consultation on Incontinence. The present study demonstrated good features for the Italian version of the PFDI-20 questionnaire., (© 2023. The International Urogynecological Association.)

Introduction: Pelvic organ prolapse (POP) is a widespread condition affecting from 40% to 60% of women. Reconstructive vaginal surgeries are the most commonly performed procedures to treat POP. Among those, uterosacral ligament suspension (USLS), which is usually performed transvaginally, preserves pelvic statics and dynamics and appears to be an effective method. Laparoscopic USLS is a valid alternative to vaginal approach, and the aim of our review is to confirm its safety and feasibility and to compare clinical outcomes among the procedures., Materials and Methods: Following the recommendations in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, we systematically searched the PubMed and Scopus databases in December 2022. We made no restriction on the publication year nor on the country. Data about POP-Q recurrence rate (RR), intraoperative and postoperative complications (graded according to Clavien-Dindo classification), readmission rate, and reoperation rate were collected and analyzed. We used comparative studies for meta-analysis., Results: A total of nine studies fulfilled inclusion criteria: two articles were non-comparative retrospective observational studies, three more articles were comparative studies where laparoscopic USLS was confronted with other surgical techniques (only data of laparoscopic USLS were analyzed), and four were comparative retrospective cohort studies between laparoscopic and vaginal USLS procedures. The comparative studies were enrolled in meta-analysis. Patients were analyzed concerning perioperative risks and the risk of recurrence. The meta-analysis highlighted that there was no clear inferiority of one technique over the other., Discussion: Laparoscopic USLS is a technique with a low complication rate and low recurrence rate. Indeed, laparoscopic procedure allows better identification of anatomical landmarks and access to retroperitoneum. Moreover, efficacy over time and durability of Laparoscopic (LPS) USLS was also observed. However, these data should be weighed in light of the length of follow-up, which was in a very short range. Further, focused and prospective studies will be necessary to confirm this finding., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Ronsini, Pasanisi, Cianci, Vastarella, Pennacchio, Torella, Ercoli and Colacurci.)

(1) Background: This narrative review aimed to analyze the epidemiological, clinical, surgical, prognostic, and instrumental aspects of the link between pelvic organ prolapse (POP) and lower urinary tract symptoms (LUTS), collecting the most recent evidence from the scientific literature. (2) Methods: We matched the terms "pelvic organ prolapse" (POP) and "lower urinary tract symptoms" (LUTS) on the following databases: Pubmed, Embase, Scopus, Google scholar, and Cochrane. We excluded case reports, systematic reviews, articles published in a language other than English, and studies focusing only on a surgical technique. (3) Results: There is a link between POP and LUTS. Bladder outlet obstruction (BOO) would increase variation in bladder structure and function, which could lead to an overactive bladder (OAB). There is no connection between the POP stage and LUTS. Prolapse surgery could modify the symptoms of OAB with improvement or healing. Post-surgical predictive factors of non-improvement of OAB or de novo onset include high BMI, neurological pathologies, age > 65 years, and the severity of symptoms; predictors of emptying disorders are neurological pathologies, BOO, perineal dysfunctions, severity of pre-surgery symptoms, and severe anterior prolapse. Urodynamics should be performed on a specific subset of patients (i.e., stress urinary incontinence, correct surgery planning), (4) Conclusions: Correction of prolapse is the primary treatment for detrusor underactivity and for patients with both POP and OAB.

•Anorectal functional pain syndrome is a very often disabling disease with a consequent significant negative impact on the patient's quality of life. Chronic proctalgia, in many patients, is secondary to the paradoxical contraction of the pelvic floor and associated with a dissynergy between the thorax-abdomen and the pelvic floor. •The use of radiofrequency diathermy with a system of static electrodes associated with biofeedback represents a valid rehabilitation option for those patients suffering from anorectal functional pain syndrome because it reduces pain and paradoxical contraction of the levator ani and improves quality of life of the patient. Background - Anorectal functional pain syndrome, also called chronic proctalgia, represents a neglected clinical entity and often confused with other syndromes such as vulvodynia or acute proctalgia. It is a very often disabling disease with a consequent significant negative impact on the patient's quality of life. Chronic proctalgia, in many patients, is secondary to the paradoxical contraction of the pelvic floor and associated with a dissynergy between the thorax-abdomen and the pelvic floor. To improve symptoms in functional anorectal pain syndromes, various rehabilitation techniques are used with the aim of promoting relaxation of the pelvic floor; however, to improve defecatory dynamics in patients with levator ani syndrome, only biofeedback has shown efficacy in a randomized study. The aim of this work is to evaluate whether a rehabilitation protocol with manometric biofeedback and radiofrequency diathermy (mt100 Fremslife emotion Tecar) reduces pain and paradoxical contraction of the levator ani and improves the quality of life in patients with anorectal pain syndromes. functional. Methods - This was a prospective study on 30 patients (20 women and 10 men) with anorectal functional pain syndrome and paradoxical contraction of the pelvic floor enrolled at the UOC of General, Minimally Invasive, Oncological and Obesity Surgery of the AOU "Luigi Vanvitelli" of Naples, Italy, from September 2021 to May 2022. All patients were evaluated with a coloproctological specialist visit followed by anorectal manometry and evaluation of altered clinical physiatric parameters (Brusciano Score). The protocol consisted of 10 rehabilitation sessions of the pelvic floor once a week and lasting approximately 45 minutes. During the sessions the patients were subjected to diathermy / radiofrequency treatment (10 minutes) with a static resistive electrode on the diaphragm, during which they were required to breathe diaphragmatically and to become aware of the perineal muscles, under the supervision of a physiotherapist; followed by application of diathermy with static capacitive (5 minutes) and resistive (10 minutes) electrode at the lumbar level. This was followed by the use of manometric biofeedback (15 minutes of tonic / phasic exercises) in order to instruct the patient on the reflex mechanism to obtain a voluntary relaxation of the external anal sphincter. The variables evaluated were Pain (VAS 0-10) and the questionnaire on the impact of colorectal and anal pathologies on the quality of life (CRAIQ-7) at the beginning, after 3 months and at the end of the treatment. Results - After 10 weeks, the rehabilitation treatment combined with diathermy and manometric biofeedback proved effective in the short term with a reduction in the scores of the Vas scale and CRAIQ-7 questionnaire and an increase in the percentage of release of the anal muscles on anorectal manometry. Conclusion - The use of radiofrequency diathermy with a system of static electrodes associated with biofeedback represents a valid rehabilitation option for those patients suffering from anorectal functional pain syndrome because it reduces pain and paradoxical contraction of the levator ani and improves quality of life of the patient.
