Hysteroscopy is an endoscopic diagnostic and therapeutic method traditionally performed under general anesthesia but increasingly under local anesthesia. Today, it is considered the gold standard in gynecology. This minimally invasive procedure allows for a detailed assessment of the uterine cavity's interior and the removal of abnormal changes within it and is applicable to patients of all ages. Background/Objectives: The purpose of the present study was to evaluate pain during hysteroscopy under local anesthesia at different stages of the procedure, identifying which stage is the most painful (GUBBINI Mini Hystero-Resectoscope; Tontarra Medizintechnik, Tuttlingen, Germany). Methods: The study included patients between the ages of 21 and 80 years. They were divided into two groups: the diagnostic hysteroscopy (HD) and the operative hysteroscopy (HO) groups. Pain measurements on the VAS scale were taken at each stage of the hysteroscopic procedure. After each stage, the operator asked the patient to indicate the maximum perceived pain value: after pericervical anesthesia was administered (VAS1), during the installation of equipment (between the removal of the speculum and the insertion of the hysteroscope into the vagina) (VAS2), after insertion of the hysteroscope and visualization of the external orifice of the cervical canal (VAS3), after passage of the hysteroscope through the cervical canal (VAS4), and after completion of the procedure in the uterine cavity (VAS5). The duration of each stage of the procedure was measured with a stopwatch: administration of pericervical anesthesia (T1), time between the removal of the speculum and the insertion of the hysteroscope into the vagina (T2), insertion of the hysteroscope into the vagina until the outer orifice of the cervical canal became visible (T3), passage of the hysteroscope through the cervical canal (T4), and the hysteroscopy procedure itself (T5). Results: The highest pain rating was for the canal passage stage (VAS4: 2.47 ± 2.48 points), followed by the procedure itself (VAS5: 2.12 ± 2.33 points). Anesthesia was also reported as quite painful, while the lowest pain was noted during the assembly stage. Overall pain scores for the entire procedure (VASmax) ranged from 3.5 ± 2.37. Conclusion: In conclusion, we found that the passage through the cervical canal was the most painful moment. Overall, hysteroscopy under pericervical anesthesia was not associated with significant pain. Special attention should be given to postmenopausal patients, as they experience more pain during the passage of the hysteroscope through the cervical canal. This group may benefit from additional pain management strategies during the procedure. [ABSTRACT FROM AUTHOR]

Pain accompanying medical procedures can be considered in the "mind-body" problem of accounting for and describing the relationship between mental and physical processes (psyche and soma). Background/Objectives: The purpose of this study is to evaluate the severity of pain among patients undergoing a minihysteroscopy procedure under local anesthesia using the "GUBBINI SYSTEM" (GUBBINI Mini Hystero-Resectoscope; Tontarra Medizintechnik, Tuttlingen, Germany) and to assess the association of various covariates with pain during the procedure, including patient emotional state. Methods: This study included 171 patients admitted to the Center for Hysteroscopy under Local Anesthesia at the Heliodor Święcicki Gynecological and Obstetrical Clinical Hospital of the Karol Marcinkowski Medical University in Poznań, Poland, for hysteroscopic treatment under local anesthesia (paracervical, using lignocaine). The Center for Hysteroscopy is the first certified "CENTER OF EXCELLENCE" of The International Society for Gynecologic Endoscopy (ISGE) in Poland. Results: A positive relationship was observed between alexithymia and its trait of difficulty identifying emotions and pain, as well as between perceived pain and one of the deficits of emotional processing—signs of unprocessed emotion. Conclusions: In conclusion, before the hysteroscopy, adequate information and counseling related to the procedure can effectively reduce the pain and anxiety levels of the women, and nurses can navigate this stressful process. Providing education and counseling to all women undergoing hysteroscopy, and explaining the procedure in detail, should be the preferred approach. [ABSTRACT FROM AUTHOR]

Background: Hysteroscopy currently represents the gold standard for the diagnosis and treatment of intrauterine pathologies. Recent technological progress has enabled the integration of diagnostic and operative time, leading to the "see and treat" approach. Diode laser technology is emerging as one of the most innovative and intriguing techniques in this context. Methods: A comprehensive search of the literature was carried out on the main databases. Only original studies reporting the treatment of intrauterine pathologies using diode laser were deemed eligible for inclusion in this systematic review (PROSPERO ID: CRD42023485452). Results: Eight studies were included in the qualitative analysis for a total of 474 patients undergoing laser hysteroscopic surgery. Eighty-three patients had female genital tract abnormalities, 63 had submucosal leiomyomas, 327 had endometrial polyps, and one patient had a scar pregnancy. Except for leiomyomas, whose technique already included two surgical times at the beginning, only seven patients required a second surgical step. Cumulative rates of intraoperative and postoperative complications of 2.7% and 0.6%, respectively, were reported. Conclusions: Diode laser through "see and treat" hysteroscopy appears to be a safe and effective method. However, additional studies with larger sample sizes and improved designs are needed to consolidate the evidence currently available in the literature. [ABSTRACT FROM AUTHOR]

Purpose: This systematic review aims to comprehensively assess the safety and efficacy of transvaginal morcellation within an enclosed bag in gynecological surgeries, with a focus on its benefits, potential risks, and recommendations for its use., Methods: We conducted a comprehensive search of Epistemonikos, Web of Science, Medline (PubMed), Scopus, and Cochrane databases for studies on transvaginal contained morcellation in adult patients undergoing gynecological surgeries. The review included 22 studies that met the inclusion criteria, encompassing diverse surgical procedures, patient profiles, and outcomes. These studies were thoroughly reviewed and analyzed to assess the safety and efficacy of the morcellation technique., Results: Key findings from the selected studies indicate that transvaginal morcellation within an enclosed bag offers several advantages in gynecological surgeries, including reduced invasiveness, shorter operative times, and minimal blood loss when compared to conventional methods. The risk of tumor recurrence or dissemination appears to be low when appropriate precautions are taken, emphasizing the technique's safety, especially when performed by experienced surgical teams. While some studies reported complications, these were generally not directly associated with the morcellation technique., Conclusion: Transvaginal morcellation within an enclosed bag demonstrates potential as a safe and effective option for gynecological surgeries. The technique offers the benefits of minimally invasive procedures, including reduced bleeding, shorter recovery times, and improved cosmetic outcomes. This review also highlights the need for standardization in study methodologies and reporting, as the heterogeneity in outcomes across the selected studies poses challenges in drawing definitive conclusions., (© 2024.

Uterine fibromas are the most common benign uterine tumors. Although the majority of leiomyomas remain asymptomatic, they can cause serious clinical problems, including abnormal uterine bleeding, pelvic pain, and infertility, which require effective gynecological intervention. Depending on the symptoms as well as patients' preferences, various treatment options are available, such as medical therapy, non-invasive procedures, and surgical methods. Regardless of the extent of the surgery, the preferred option is the laparoscopic approach. To reduce the risk of spreading occult malignancy and myometrial cells associated with fragmentation of the specimen before its removal from the peritoneal cavity, special systems for laparoscopic contained morcellation have been developed. The aim of this review is to present the state-of-the-art contained morcellation. Different types of available retrieval bags are demonstrated. The advantages and difficulties associated with contained morcellation are described. The impact of retrieval bag usage on the course of surgery, as well as the effects of the learning curve, are discussed. The role of contained morcellation in the overall strategy to optimize patient safety is highlighted. [ABSTRACT FROM AUTHOR]

Endometrial polyps are one of the most common pathological conditions in gynecology. Hysteroscopy is the gold standard for the diagnosis and treatment of endometrial polyps. The purpose of this multicenter, retrospective study was to compare patients' pain perception during an operative hysteroscopic endometrial polypectomy in an outpatient setting with two different hysteroscopes (rigid and semirigid) and to identify some clinical and intraoperative characteristics that are related to worsening pain during the procedure. We included women that underwent, at the same time as an diagnostic hysteroscopy, the complete removal of an endometrial polyp (using the see-and-treat strategy) without any kind of analgesia. A total of 166 patients were enrolled, of which 102 patients underwent a polypectomy with a semirigid hysteroscope and 64 patients underwent the procedure with a rigid hysteroscope. No differences were found during the diagnostic step; on the contrary, after the operative procedure, a statistically significant greater degree of pain was reported when the semirigid hysteroscope was used. Cervical stenosis and menopausal status were risk factors for pain both in the diagnostic step and in the operative one. Our results confirm that operative hysteroscopic endometrial polypectomy in an outpatient setting is an effective, safe, and well-tolerated procedure and indicate that it might be better tolerated if a rigid rather than semirigid instrument is used.

Pain is a major barrier to successful outpatient hysteroscopy. Multiple factors can cause pain during the procedure including patient factors such as cervical stenosis and anxiety and procedural factors such as hysteroscope diameter and operative procedures. Pain relief strategies tailored to needs for Hong Kong women may enhance patient satisfaction and the success rate of outpatient hysteroscopic procedures. [ABSTRACT FROM AUTHOR]

Background: Vaginally assisted laparoscopic sacrocolpopexy (VALS) refers to the placement of synthetic meshes through the vagina in addition to traditional laparoscopic sacrocolpopexy. In this study, we aimed to investigate the medium- to long-term efficacy and safety of VALS for treating stage III–IV pelvic organ prolapse (POP). Methods: The study was designed as a case series at a single center. Patients with stage III–IV POP in our hospital from January 2010 to December 2018 were included. Perioperative parameters, objective and subjective outcomes, and complications were assessed. Results: A total of 106 patients completed the follow-up and were included in our study. Within a median follow-up duration of 35.4 months, the objective cure ratio of VALS reached 92.45% (98/106), and the subjective success rate was 99.06% (105/106). Patients reported significant improvements in subjective symptoms. In eight patients suffering anatomic prolapse recurrence, two posterior POP cases were treated by posterior pelvic reconstruction surgery, while six anterior POP cases did not need surgical therapies. The reoperation rate was 1.89% (2/106). No intraoperative complications occurred. Three patients (2.83%) had postoperative fever, and one (0.94%) had wound infection during hospitalization. Six patients (5.66%) had mesh exposure on the vaginal wall, and de novo urinary incontinence occurred in two patients (1.89%) during the follow-up period. Conclusion: VALS is an effective and safe surgical method for treating severe POP. Therefore, VALS should be considered in the treatment of severe POP due to its favorable subjective and objective outcomes, relatively low rate of infection and acceptable rate of mesh exposure.

Background: The main barriers to 'vulnerable migrants' receiving good quality primary care are language and administration barriers. Little is known about the experiences of healthcare discrimination faced by migrants from different cultural groups. The aim was to explore vulnerable migrants' perspectives on primary healthcare in a UK city. Methods: Three focus groups and two semi-structured interviews were aided by interpreters. These were analysed against a pre-developed framework based on national standards of care for vulnerable migrants. Recruitment was facilitated via a community organisation. Results: In total, 13 participants took part, six women and seven men. There were five Arabic speakers, four Farsi speakers and four English speakers. Themes included access to primary care, mental health, use of interpreters, post-migration stressors and cultural competency. Conclusion: Vulnerable migrants perceived high levels of discrimination and reported the value of a respectful attitude from health professionals. Appointment booking systems and re-ordering medication are key areas where language barriers cause the most disruption to patient care. Medication-only treatment plans have limitations for mental distress for this population. Community-based therapies which manage post-migration stressors are likely to enhance recovery.

In the context of the ever-increasing energy crisis, electrocatalytic water splitting has attracted widespread attention as an effective means to provide clean energy. However, the oxygen evolution reaction (OER), which is an important anodic half reaction, shows very slow kinetics due to the multi-step electron transfer process, which severely restricts the efficiency of energy conversion. Herein, we used a simple solvothermal method to dope iron into the cobalt-containing hydroxide precursor, and successfully prepared the Fe-doped Co-oxide electrocatalyst Co3−xFexO4-0.01. It only needs an overpotential of 294 mV to perform the OER at a current density of 10 mA cm−2, and has a low Tafel slope of 47.3 mV dec−1. Moreover, Co3−xFexO4-0.01 has excellent stability. There is no significant increase in the overpotential for oxygen evolution at a current density of 10 mA cm−2 after nearly 20 h. BET surface area test and XPS spectroscopy results show that Fe doping provides more mesopores and oxygen bridges, which is conducive to the construction of active sites and electronic regulation during the OER. This work can help design more bimetallic based highly active OER materials. [ABSTRACT FROM AUTHOR]

The essay is dedicated to the late stage of career of Pietro Bianchi, painter from Como who died in Rome in 1732. The unpublished documents (his will, the inventory of lost collection in his apartment in Palazzo di Spagna in Rome, and other documentary evidences) allow identifying the artist as "il Bustino", the adopted son and pupil of Antonio Crespi Castoldi, and painter in Lombardia in late XVII siecle and the beginning of XVIII siecle. This contribution offers the opportunity to understand his role as an agent and as a painter for the Spanish and Potuguese Crowns and help understanding his relationship with Odescalchi family and with the cardinal and ambassador Francesco Acquaviva.

Purpose: This study aimed to address knowledge gaps about post-traumatic stress disorder (PTSD) in mid-age and older adults, with particular attention to the relationship of PTSD with nutrition and with ethnicity and immigrant status. Methods: Binary logistic regression analysis of weighted comprehensive cohort data from the baseline Canadian Longitudinal Study on Aging (CLSA; n = 27,211) was conducted using the four-item Primary Care-PTSD tool (outcome) and immigrant status by ethnicity (Canadian-born white, Canadian-born minority, immigrant white, immigrant minority). Covariates included various social, economic, nutrition and health-related variables. Results: After controlling for socioeconomic and health variables, immigrants from minority groups had significantly higher odds of PTSD compared to their Canadian-born counterparts, whereas white immigrants had lower odds of PTSD. These relationships were significantly robust across seven cluster-based regression models. After adjusting for ethnicity/immigrant status, the odds of PTSD were higher among those earning lower household incomes, widowed, divorced, or separated respondents, ever smokers, and those who had multi-morbidities, chronic pain, high nutritional risk, or who reported daily consumptions of pastries, pulses and nuts, or chocolate. Conversely, those 55 years and over, who had high waist-to-height ratio, or who consumed 2–3 fiber sources daily had significantly lower odds of PTSD. Conclusion: Interventions aimed at managing PTSD in mid-age and older adults should consider ethnicity, immigrant status, as well as socioeconomic, health, and nutrition status.

Background: Previous studies have already proven high rates of common mental disorders in Syrian refugees. Nevertheless, little is known about the patterns of somatic distress among this refugee population. For this reason, we aimed to examine the prevalence, co-occurrence, and risk factors of somatic distress among Syrian refugees in Germany.Methods: This study analyzes the second measurement point (N = 116) of a prospective register-based survey among 200 adult Syrian refugees with residence permission in Germany. The survey consisted of information on sociodemographic and migration-specific characteristics, health care utilization, traumatic life events, acculturative stress (Barcelona Immigration Stress Scale (BISS); subscales: perceived discrimination, intercultural contact stress, homesickness, and general psychosocial stress), and self-reported outcomes of somatic distress (Patient Health Questionnaire (PHQ-15)), depression (PHQ-9), generalized anxiety disorder (GAD-7), and post-traumatic symptoms (Essen Trauma Inventory (ETI)).Results: Almost half of the respondents (49.1%) were identified as being at risk of somatic distress (PHQ-15 score ≥ 6), and even 24.1% being bothered by moderate-to-severe levels of somatic distress (PHQ-15 score ≥ 10). The most robust associations with somatic distress were found for female gender, the amount of health care utilization, multiple trauma exposures, general psychosocial stress, and self-reported depression and anxiety symptoms. High comorbidities with somatic distress were shown for all of the common mental disorders studied.Conclusions: The presented study reveals a significant risk of somatic distress among this displaced population and highlights implications for policy and health care providers.

Catalysts for heterogeneous catalytic reactions, particularly for total water splitting, is receiving tremendous attention and sustainable fuel development is highly relied on the catalysts development, where both the material and its method of preparation are important. Here, bimetallic multi‐phasic catalysts containing nickel (Ni) and iron (Fe) are synthesized using a simple but reproducible polyol method, which results in to different sponges having control over their chemical stoichiometry. The macroporous sponges thus developed contain metallic Ni, NiO, and Fe2O3, where their proportionate content can be varied with initial precursor ratio. The NiFe15 so developed is having the best oxygen evolution performance in terms of overpotential, kinetics, and charge transfer properties, and it is found to be better than the benchmarked IrO2 based catalysts. The hydrogen evolution from the other ratio, NiFe5, is found to be better than other Ni and Fe based samples, and it is found to be very close to the hydrogen evolution performance of platinum. An alkaline water electrolysis full cell is constructed, devoid of any precious metals but with NiFe5 and NiFe15, and the overall splitting potential for the benchmarked current density of 10 mAcm−2 is found to be 1.62 V only, which is better or on par with the other singly/multi‐phasic systems reported so far. Hence the work presented here shows the possibilities of futuristic electrochemical technologies with viable catalysts, and a detailed study is presented. [ABSTRACT FROM AUTHOR]

Exploring high-performance and stable electrocatalysts for the oxygen evolution reaction (OER) is critical for the conversion and storage of renewable energy. Herein, a novel strategy was developed for the construction of dispersive nickel phosphide (Ni2P) embedded in two-dimensional (2D) amorphous alumina arrays on three-dimensional (3D) nickel foam (NiP–Al2O3/NF) electrocatalysts via the reduction of a layered double hydroxide (LDH) precursor. Owing to its unique 3D nano/micro-architecture, multi-porous structure, interconnected conductive skeleton, and highly dispersive Ni2P active sites, the NiP–Al2O3/NF electrocatalyst exhibited excellent OER activity with overpotential as low as 193 mV at 10 mA cm−2 in a 1.0 M KOH solution and superior catalytic activity for the oxidation of 5-hydroxymethylfurfural in alkaline media. Density functional theory calculations demonstrated that the introduction of P to Ni could effectively reduce the OER overpotential. Furthermore, benefiting from the flexibility of compositional tailoring of both the brucite-like layers and interlayer anions of LDHs, the synthesis strategy presented here can be easily extended to the fabrication of various nanostructured noble-metal-free functional materials, which are expected to have wide application prospects in many domains, especially in catalysis.

Background: Somatic and psychopathological conditions (e.g., anxiety, depression, post-traumatic stress disorder, and somatization) are frequent among immigrants belonging to various ethnic groups. Worldwide findings on the epidemiology regarding specific mental conditions still vary with respect to different migration samples and migration contexts. This inconsistency also holds true in the incidence of somatization among migrants. We carried out a systematic review analyzing the relationship between migration and somatization by providing a qualitative data synthesis of original research articles on the topic. Methods: According to PRISMA guidelines, we conducted a systematic search of the literature on PubMed, Scopus, ISI Web of Science, PsycINFO, Google Scholar, and ScienceDirect. The articles were selected using multiple combinations of relevant search terms (e.g., defined somatization and related disorders, and migration status). Each database was searched systematically from January 2000 to December 2017. Results: The initial search identified 338 records, of which 42 research reports met the predefined inclusion criteria and were analyzed. Most studies (n = 38; 90%) were cross-sectional. The main findings of this study are that migrants with somatization exhibited more psychological distress, had an increased perceived need for healthcare service utilization, and reported more post-migration living difficulties and/or post-traumatic stress disorder than those without somatization. It was also found that specific individual features mediate the association between somatization and migration. The prevalence and correlates of somatization were found to vary across the immigrant groups, depending on cultural variation in reasons for migration, stress exposure, explanatory models of illness, coping, and other individual variables. Conclusion: Somatization is a challenge for health professionals due to its vague nature. In this regard, clinical management of immigrant patients should include further efforts to address emotional distress, with special attention to social, cultural, and linguistic differences.

This work aims to illustrate the importance of selecting the best substrate and ‘powder to electrodes’ fabrication technique when screening new OER catalysts. A well-established water oxidation catalyst, RuO2 powder is used to fabricate different types of commonly used electrodes found in literature including: dropcast electrodes, doctor-blade electrodes and pressed electrodes. A variety of support substrates are used based on materials such as platinum, titanium, nickel and glassy carbon. Additionally, a variety of substrate geometries are also investigated, including: discs, foils and foams. The results show that the OER activity of the RuO2 powder is significantly varied depending on the electrode fabrication and substrate combination utilised. These findings show the importance of screening different substrates and fabrication methods when investigating the OER with new powder materials. [ABSTRACT FROM AUTHOR]

The present research evaluated the psychosocial health and quality of life of North African (NA) immigrant women living in Italy. A survey of 205 NA-born and Italian-born women was carried out. Psychosocial, sociodemographic and migration data were collected. Anthropometric indices were computed by direct measurements of height, weight, waist and hip circumferences. Multivariate analysis showed that the main explanatory variable for all dimensions of psychosocial status was the migrant status. Other explanatory variables were educational level and number of children for psychological discomfort, and weight status for well-being, quality of life and stress. Anthropometric indices were explanatory variables for quality of life. In conclusion, this study provides further evidence of higher psychological stress and discomfort and lower well-being and quality of life in immigrant women. Public social support is necessary to control, maintain and improve the mental health outcomes of immigrant communities in the host country. [ABSTRACT FROM AUTHOR]

Summary: Objective: Functional neurological disorders (FNDs) and psychogenic nonepileptic seizures (PNES) are likely as common in Sub‐Saharan Africa (SSA) as in the rest of the world, but there is a dearth of literature on the epidemiology and clinical presentation of these disorders in Africa. The purpose of this paper is to describe a case series of FNDs presenting to a referral hospital in SSA. In addition, we review the existing literature on FNDs in Africa. Methods: A hospital‐based retrospective cross‐sectional study was conducted to determine the prevalence, epidemiology, and clinical phenotype of FNDs and PNES in a referral hospital in Northern Tanzania over a 6‐year period (2007–2013). Results: Of 2,040 patients presenting with neurological complaints, 44 (2.2%) were diagnosed with FNDs. Half (n = 22) had the clinical presentation of PNES. Age of presentation for FNDs and PNES peaked in the teen years 12–19 (n = 21 48%; and n = 14, 63%, respectively), and the majority were female (n = 30, 68%; and n = 14, 63%, respectively). The majority presented acutely with short‐lived and self‐limiting symptoms (only 2 recurrent cases). Literature review revealed multiple reports of "mass hysteria" in SSA often meeting the clinical criteria of epidemic FNDs. Significance: FNDs and PNES occur in Africa with age and gender distribution comparable to that found elsewhere. Although the percentage of FND cases overall was relatively low (2.2%), it is likely to be an underestimate because not all cases were recorded, and cases may be appropriately managed locally before patients are referred to a hospital. PNES was the most common phenotype of FNDs reported, and the African phenotype may be short‐lived and self‐limiting rather than chronic and recurrent, as reported elsewhere in the world. PNES presentations may also occur in clusters, which may have cultural significance in Africa. FNDs in Africa appear to be underreported, particularly over the last 30 years. [ABSTRACT FROM AUTHOR]

Purpose: This review covers the most recent evidence to discuss the incidence of occult uterine sarcoma, whether morcellation increases tumor dissemination or mortality, and whether there is a difference between different types of morcellation. We will also discuss techniques to reduce the spread of an undiagnosed uterine sarcoma.Method: A comprehensive literature search was made in Pubmed, Medline, the Cochrane Library, and Google Scholar for articles related to the incidence of occult uterine sarcoma after morcellation.Results: Fibroids are benign uterine tumors and are a common indication for gynecologic surgery. Increasingly, gynecologists are approaching these surgeries with minimally invasive techniques. Uterine sarcomas are rare malignant mesenchymal tumors that are difficult to distinguish preoperatively from uterine fibroids.Conclusion: During a minimally invasive surgery, there is a risk of disseminating an occult sarcoma during tissue extraction. Minimally invasive gynecologists are tasked with balancing taking a minimally invasive approach, which is shown to result in better patient outcomes, with minimizing the risk of spreading an occult sarcoma.

The rational design of noble metal-free electrocatalysts that are highly active, robustly stable, and capable of delivering large current densities (＞500 mA cm−2) at low applied potentials (＜300 mV), in particular for oxygen evolution reaction (OER), is critical for practical use in electro-driven water-splitting devices. Herein, we report a facile scalable and one-step electrochemical deposition approach for the development of a self-supported 3D nanoporous S-doped amorphous NiFe2O4/Ni3Fe composite electrode with outstanding OER electrocatalytic activity and robust durability in alkaline media. Benefiting from the 3D nanoporous architectures and their in situ growth on a highly conductive substrate, the novel S-doped NiFe2O4/Ni3Fe composite electrode offers an ideal platform for fast electron transport and efficient mass transport. It also provides abundant active surface area as well as accessible active sites for a catalytic reaction. Impressively, the S-doped composite electrode displays superior OER activity in 1.0 M KOH that compares favorably with the state-of-the-art RuO2 catalyst. Low overpotentials of 260 and 285 mV (iR corrected) are required to reach long-term stable current densities of 100 and 500 mA cm−2 for OER, respectively. The electrolyzer cell obtained by pairing this S-doped composite electrode as an anode with a Ni–Mo based cathode for overall water-splitting works efficiently in both 1.0 M (1.52 V for 10 mA cm−2 and 1.79 V for 100 mA cm−2) and 30 wt% KOH (1.69 V for 100 mA cm−2) solutions, with long durability for over 220 h. Such catalyst couple exhibits superior catalytic performance and holds great promise for potential application in electrochemical water splitting. [ABSTRACT FROM AUTHOR]

Surveys are used to infer the level of social integration of immigrants. Item response theory helps to describe the relationship among responses to test items and latent traits of interest. However, in the presence of nonignorable missing data, which are omitted responses depending on the latent traits to be measured, estimates of the model parameters are biased. To account for nonignorable missing data, the quantity and quality of contacts between immigrants and natives (so called “social integration”) are taken into account through a linear function of the response propensity. Higher education, no intention to migrate again, young age, Albanian nationality, and declaring a non-Muslim religion or none, comparatively favor social integration. [ABSTRACT FROM AUTHOR]

Central descent due to a level 1 defect is a main component in pelvic organ prolapse (POP) reconstructive surgery, whether for symptomatic apical prolapse or for the prolapse repair of other compartments. A recent growth in the rate of native tissue repair procedures for POP, following the US Food and Drug Administration (FDA) warnings regarding the safety and efficacy of synthetic meshes, requires a re-evaluation of these procedures. The safety, efficacy, and determination of the optimal surgical approach should be the center of attention. Functional outcome measures and patient-centered results have lately gained importance and received focus. A comprehensive literature review was performed to evaluate objective and subjective outcomes of apical prolapse native tissue repair, with a special focus on studies reporting impact on patients' functional outcomes, quality of life, and satisfaction. We performed a MEDLINE search for articles in the English language by using the following key words: apical prolapse, sacrospinous ligament fixation, uterosacral ligament suspension, sacral colpopexy, McCall culdoplasty, iliococcygeus vaginal fixation, and functional outcomes. We reviewed references as well. Despite a prominent shortage of studies reporting standardized prospective outcomes for native tissue repair interventions, we noted a high rate of safety and efficacy, with a low complication rate for most procedures and low recurrence or re-treatment rates. The objective and subjective results of different procedures are reviewed. Functional outcomes of native tissue repair procedures have not been studied sufficiently, though existing data present those procedures as favorable and not categorically inferior to sacrocolpopexy. Apical compartment prolapse repair using native tissue is not a compromise. Functional outcomes of native tissue repair procedures are favorable, have a high rate of success, improve women's quality of life (QoL), and result in high rates of patient satisfaction. This subject requires further long-term, standardized prospective studies following the International Continence Society/International Urogynecologists Association guidelines for surgical outcomes report, with the focus on patient-centered functional outcomes.

Background: Electromechanical power morcellation is an important tool of modern laparoscopy. Recent reports on the spread of previously undetected malignancy by power morcellation indicate the need for additional protective devices to reduce this risk. We conducted a study to obtain the first data concerning the safety of an endobag with three closable ports during morcellation and subsequent bag extraction under in vitro conditions, mimicking the settings in our operating theater. The second purpose of the study was to establish a minimal width of the skin incision necessary to safely extract the sealed bag after morcellation.Methods: The morcellation test was carried out on 11 stained porcine muscle tissue samples with one additional sample as a control. The insufflation pressure was set at 12 mmHg. After filling the endobag with blue dye solution, an additional extraction test was conducted by pulling the closed bag through a template with apertures of various diameters. For each opening, a series of ten bag extractions was carried out.Results: No loss of solid material or fluid was recorded during the morcellation test. The extraction test showed a loss of fluid for template openings smaller than 18 mm. The force necessary to extract the bag was inversely related to the width of the aperture.Conclusions: The data suggest that under the evaluated conditions, the use of a closable morcellation bag can considerably improve the patient's safety during morcellation. Further studies are necessary to evaluate the influence of the bag on operating time, intervention costs and complications. [ABSTRACT FROM AUTHOR]

Background: Hysteroscopic morcellation removes uterine pathology under direct visualization with continuous real-time tissue fragment removal. Objective: The aim of this study was to explore the feasibility of hysteroscopic morcellation across a diverse set of facilities, including both surgical and office-based settings. Design: This was a prospective, single-arm, multicenter registry development (Canadian Task Force classification II-3). Materials and Methods: Thirty-four U.S. obstetrics and gynecology facilities enrolled subjects into the registry. Inclusion criteria were women ages 18-65 with indications for hysteroscopic myomectomy and/or polypectomy who were treated with the MyoSure® Hysteroscopic Tissue Removal System (Hologic Inc., Marlborough, MA). Intrauterine lesion type/size and removal parameters, adverse events (AEs), and physician satisfaction ratings were recorded. Results: A total of 559 pathologies (187 fibroids; 372 polyps) were removed from 278 registered subjects (mean age: 43.9 ± 9.0 years), with 250 procedures (89.9%) performed in an ambulatory surgery center or hospital outpatient setting and 28 (10.1%) in a gynecologic office setting. Most patients ( n = 206, 74.1%) were treated for abnormal uterine bleeding, and 42 (15.1%) were treated for infertility. Mean fibroid diameter was 2.2 ± 1.2 cm. Mean polyp diameter was 1.3 ± 1.0 cm. Overall mean percentage of pathology removed was 95.4% (polyps 99.3%, fibroids 86.8%). Five AEs included four incidents of blunt cervical trauma and a single postoperative case of pedal edema; all were considered mild and resolved spontaneously. Postprocedure surveys indicated that 95% of reporting physicians were 'satisfied' or 'highly satisfied' with device performance. Conclusions: Hysteroscopic morcellation of intrauterine pathology was accomplished safely with a high degree of physician satisfaction in 278 patients treated in diverse healthcare settings that are reflective of general community practice in the United States.

Introduction: Endoscopic techniques have successfully reduced the invasiveness of hysterectomy, when compared to open procedures. Power morcellation, as a part of the minimal invasive concept, carries the risk of disseminating cells from the tissue specimen. The present observational study reports on first experiences using a new system (More-Cell-Safe, A.M.I., Austria) for contained in-bag morcellation during laparoscopic hysterectomy.Materials and Methods: The dual opening system allows two-port access without bag puncture. The optic is protected against spread cell contamination with a disposable sleeve. Application data were prospectively recorded on the first n = 7 consecutive patients and compared to n = 7 preceding patients undergoing uncontained morcellation.Results: Bag system use was surgically successful in 6 of 7 cases (85.7 %). Morcellated specimen weight ranged from 205 to 638 g (mean 413.33 ± 176.85; median 413). In one patient, the uterine specimen (1050 g) proved too large to be placed into the bag. Average time associated to the bag use was 16.2 ± 7.65 min, ranging from 8.5 to 26.5 min (median 14 min). Removed bags contained bloody fluid with residual tissue fragments weighing overall between 21 and 85 g. Spread spindle cells were detected in two cases after uncontained morcellation, but not after in-bag morcellation.Conclusion: The experiences from our small pilot series prove technical feasibility in the clinical setting.

Introduction and hypothesis: Sacrospinous ligament fixation (SSLF) for pelvic organ prolapse repair can incur significant intraoperative hemorrhage. Management of vascular injury is challenging because of limited visualization of the surrounding pararectal space and is not well described in the literature. Methods: We evaluate cases of intraoperative venous and arterial hemorrhage during SSLF. Based on a review of the literature, we present a systematic approach to the treatment of venous and arterial hemorrhage associated with SSLF. Results: Vascular injury to the hypogastric and pudendal venous plexi may be controlled using directed compression and topical hemostatic agents. Vascular injury to the inferior gluteal artery, its coccygeal branch, or other arteries, may require embolization. Conclusion: Life-threatening bleeding is a rare complication of transvaginal SSLF. Knowledge of surrounding pelvic vascular anatomy, treatment options, and communication with ancillary staff is essential for the treatment of sacrospinous ligament hemorrhage. [ABSTRACT FROM AUTHOR]

Objective: Vaginally assisted laparoscopic sacrocolpopexy (VALS), which is a combined surgical approach where a vaginal hysterectomy is initially performed, followed by transvaginal placement of synthetic mesh and laparoscopic suspension, can be an alternative to overcome the dissection, suturing limitations of laparoscopic sacrocolpopexy. The aim of this study was to compare the operative times and middle-term anatomic outcomes of women with uterovaginal prolapse undergoing VALS with those of women undergoing abdominal sacrocolpopexy., Methods: This is a prospective cohort study that evaluates operation times, anesthesia times, estimated blood loss, middle-term outcomes, perioperative and postoperative complications. We compared the results of 47 women who had the VALS to that of 32 abdominal sacrocolpopexy (AS)., Results: The mean follow up was 22.4 months for AS group and 20.5 months for VALS group. The VALS group (median 1 day) had shorter hospitalization duration than the AS group (median 3 days). The mean operation time was significantly shorter in the VALS group (125.9 minutes) than the AS group (151.9 minutes) (P = .03). There was no significant difference in perioperative and postoperative complication rates. Objective failure rate (8.5% in VALS, 15.6% in AS), subjective failure rates (6.4% in VALS, 9.4% in AS), recurrence (2.1% in VALS, 9.4% in AS) and mesh exposition rates (2.1% in VALS, 9.4% in AS) were similar in both procedures., Conclusions: VALS with shorter operative time and hospitalization than conventional AS is a promising modification minimally invasive technique for sacrocolpopexy especially for those inexperienced in laparoscopic sacrocolpopexy., (© 2020 John Wiley & Sons Australia, Ltd.)
