Unilateral pectineal suspension – A new surgical approach for apical correction of pelvic organ prolapse
Authors: Bolovis D.I. , Brucker C.V.M.
Published: July 2022

Background and objectives: There are numerous vaginal and abdominal surgical approaches for the treatment of pelvic organ prolapse (POP). Even the standard techniques show great variability due to modifications depending on anatomy, available instruments and materials. Recently, the role of hysterectomy in prolapse surgery as well as the use of synthetic meshes have been questioned. Here, we present a standardised mesh-free minimally invasive pelvic floor reconstruction technique with uterus preservation.

Materials and Methods: Unilateral pectineal suspension (UPS) is carried out in five defined steps with the use of the da Vinci Xi ® surgical system. The desired anatomical result is simulated by intraoperative uterus manipulation. The cranial part of the pectineal ligament is used for lateral fixation. A non-absorbable suture is placed between the pectineal ligament and the anterior cervix to suspend the uterus in its natural anatomical position.

Main outcome measures: For outcome measurement, degree of prolapse was assessed pre- and postoperatively according to the POP-Q system.

Results: Unilateral pectineal suspension offers several advantages. Medial tension-free positioning of the uterus is achieved. The use of the cervix as fixation structure allows for excellent pelvic floor support and stable results. Normal pelvic floor mobility and natural axis of the vagina are restored.

Conclusions: Unilateral pectineal suspension is an efficient minimal-invasive mesh-free procedure which allows uterus preservation and offers reliable level I support respecting the physiological pelvic anatomy. In addition, there is no need for ureteral dissection or bowel manipulation. The technique offers clinical standardization and can easily be integrated into the spectrum of modern surgical POP repair.

Published: July 2022

Background: There is scarce information on the effectiveness of the laparoscopic single mesh sacrohysteropexy (smSHP). Attachment of a single sheet of flat mesh posteriorly to the cervix provides less mesh use and a less invasive distal mesh fixation.

Objectives: To assess medium to long-term follow-up results of patients who underwent laparoscopic smSHP utilising a less invasive technique with single sheet flat mesh.

Materials and Methods: In the present retrospective cohort study, the data of 71 women who underwent laparoscopic smSHP for apical uterine prolapse with or without colporrhaphy (anterior and/or posterior) at the urogynaecology unit of a university hospital between January 2008 and January 2020 was reviewed. Data was collected on demographics, presenting symptoms, preoperative findings, surgery, and postoperative outcomes.

Main Outcome Measures: Medium to long-term patient-reported outcomes.

Results: The median age of the study population was 44 years. Median follow-up duration was 5 years (1-12). Symptomatic recurrence over time and repeat surgery rates were 13.1% and 3.1% respectively. Comparison of the pre-operative and medium to long-term evaluation scores of the pelvic floor distress inventory-20 (PFDI-20) and assessment of the patient global impression of improvement (PGI-I) revealed long-standing improvement in pelvic floor dysfunction.

Conclusions: Laparoscopic smSHP appears to be successful and safe with low recurrence and complication rates and provides satisfactory patient reported outcomes.

What’s new? Medium to long-term patient-reported outcomes based on PFDI-20 and PGI-I surveys are satisfactory following smSHP.

Authors: Roest I , Hajiyavand A.M. , Dearn K.D. , Bongers M.Y. , Mijatovic V , Mol B.W.J. , Koks C.A.M.
Published: July 2022

Background: Oil-based contrast has been shown to have a fertility-enhancing effect during hysterosalpingography (HSG) but is not yet used during transvaginal hydro laparoscopy (THL).

Objective: To asses if additional tubal flushing with oil-based contrast during THL is feasible.

Materials and methods: Case report with video assessment. A healthy 29-year-old woman with primary unexplained subfertility, underwent a THL under local anaesthesia. First, chromopertubation was performed by methylene blue. Afterwards, tubal flushing with 3mL oil-based contrast (Lipiodol® UltraFluid, Guerbet) was performed.

Main outcome measures: In this case report we evaluated the feasibility of additional tubal flushing with oil- based contrast during THL, in terms of; the visibility of the oil-based contrast at the tubal fimbriae, the pain and acceptability scores.

Results: Both fallopian tubes were patent to methylene-blue as well as to oil-based contrast. Interestingly, the oil-based contrast came out of the fallopian tube in the form of free droplets with strong internal bonding. Furthermore, some residue of the droplets was visible on the surface of the peritoneal wall in the form of oily micro-droplets.

Conclusions: We present the first sub-fertile woman, in which additional tubal flushing with oil-based contrast during THL was performed. It is likely, that the residue of oily micro-droplets is also present inside the fallopian tube, where it may enhance the cilia movement by introducing lubrication. These lubricating characteristics of the oil-based contrast may be important for its fertility-enhancing effect. More research is necessary to confirm this hypothesis and the feasibility of tubal flushing with oil-based contrast during THL in more women.

Authors: Di Spiezio Sardo A , Saccone G , Carugno J , Pacheco L.A. , Zizolfi B , Haimovich S , Clark T.J.
Published: July 2022

Background: Endometrial cancer is the most common gynaecological neoplasia in western countries. Diagnosis of endometrial cancer requires an endometrial biopsy. A good quality endometrial biopsy allows not only the identification of the pathology, but also preoperative histologic subtype classification. Endometrial biopsy can be performed under direct hysteroscopic visualisation, but also using blind sampling techniques

Objectives: To compare endometrial biopsy performed under direct hysteroscopic visualisation versus blind sampling for the diagnosis of endometrial hyperplasia and cancer.

Materials and Methods: Systematic review and meta-analysis. Electronic databases were searched from their inception until March 2022.We included all studies comparing endometrial biopsy performed under direct hysteroscopic visualisation versus blind endometrial sampling.

Main outcome measures: Sample adequacy, failure rate to detect endometrial cancer or endometrial hyperplasia, and rate of detection of endometrial cancer. The summary measures were reported as relative risk (RR) with 95% of confidence interval (CI).

Results: Four studies with a total of 1,295 patients were included. Endometrial biopsy under direct hysteroscopic visualisation was associated with a significantly higher rate of sample adequacy (RR 1.13, 95% CI 1.10 to 1.17), and significantly lower risk of failure to detect endometrial cancer or endometrial hyperplasia (RR 0.16, 95% CI 0.03 to 0.92) compared to blind endometrial sampling. However, there was no significant difference between endometrial biopsies taken under direct hysteroscopic visualisation or blindly, with or without a preceding diagnostic hysteroscopy, in the rate of detection of endometrial cancer (RR 0.18, 95% CI 0.03 to 1.06).

Conclusion: Hysteroscopic endometrial biopsy under direct visualisation is associated with significantly higher rate of sample adequacy and is comparable to blind endometrial sampling for the diagnosis of endometrial cancer and precancer.

What is new? Hysteroscopic endometrial biopsy under direct visualisation would be expected to reduce diagnostic failure for endometrial cancer compared to blind endometrial sampling.
Homologous recombination repair deficiency (HRD) testing in newly diagnosed advanced-stage epithelial ovarian cancer: A Belgian expert opinion
Authors: Vergote I , Denys H , Altintas S , Kerger J , Baurain J-F , Bours V , Henry S , Van de Vijver K , Lambrechts D , Gennigens C
Published: July 2022

Ovarian cancer (OC) has a poor prognosis as most patients present with non-specific symptoms and the disease is mostly diagnosed at advanced stages. Approximately 90% of cases are classified as epithelial OC (EOC), a category comprising histologically and molecularly distinct tumours. Identifying reliable biomarkers and employing personalised therapies in OC subgroups is crucial for battling the disease. EOCs are often characterised by homologous recombination repair deficiency (HRD), frequently caused by inactivation of the breast cancer susceptibility (BRCA) genes. These findings have led to the development of poly- (adenosine diphosphate [ADP])- ribose polymerase inhibitors (PARPi), which are synthetically lethal to HRD tumour cells. Both patients with HRD and non-HRD tumours can benefit from PARPi therapy in the recurrent setting. Moreover, recent phase III trials in patients with newly diagnosed advanced-stage OC have demonstrated greater clinical benefit from PARPi in treating HRD than non-HRD tumours. These findings offer new opportunities for the use of PARPi as maintenance therapy after first-line chemotherapy based on the presence of HRD. In the current article, we provide recommendations for HRD testing and treatment of patients with newly diagnosed advanced-stage EOC.

This study investigates the use of vaginal and oral administration of tadalafil.

Study design: This is a prospective double-blind placebo-controlled randomized controlled trial with 58 patients in an in vitro fertilization treatment with a short antagonist stimulation protocol. The study population is divided into three equal groups comparing oral and vaginal administration of tadalafil to a control group.

Results: No significant difference in endometrial thickness and number of biochemical and clinical pregnancies was found between the three groups.

Conclusion: This study could not show a significant benefit of administration of tadalafil. However, a trend towards more pregnancies in the group treated with oral tadalafil is seen, more research in specific subgroups is needed.
The shortest distance between the skin and the peritoneal cavity is obtained with fascial elevation: a preliminary prospective laparoscopic entry study
Authors: Kiran G , Yilmaz I , Aydin S , Sanlikan F , Ozkaya E
Published: July 2022

The purpose of this study was to prospectively compare the measurement of skin-to-fascia distances in the neutral state, during manual elevation and by fascial elevation in patients who underwent laparoscopic surgery. In 53 patients, the distance between the skin and anterior wall of the rectus sheath was measured prospectively in following three different ways: (1) in neutral position, (2) during manual elevation and (3) during elevation of the fascia using forceps following an infraumbilical vertical skin incision. In all patients, subcutaneous tissue up to the fascia was dissected after a vertical skin incision. The skin-to-fascia distance of 30.9 mm (14.0-52.0 mm) in the neutral position decreased to 11.1 mm (0.0-26.0 mm) during the fascial elevation, while the mean distance increased to 40.1 mm (19-70 mm) during manual elevation (p < 0.001). In the closed laparoscopic entry technique in which a Veress needle is inserted into the peritoneum through a small incision, the needle should be introduced from the shortest distance between the skin and the peritoneum. Lifting the fascia with a proper surgical instrument in suitable patients could enable us to achieve this goal.

Population planning is inevitable for a sustainable and secure future of a lower middle-income economy, like, Pakistan which stands fifth populous economy across the globe and has high population growth rate. Based on Pakistan Demographic and Health Survey 2017-18 data and by covering a sample of 12339 ever-married females, the study intends to investigate the correlates of family planning services use in Pakistan as well as the use of contraceptives across the regions and districts of Pakistan. An exploration of 34 studies (spanning over a time from 1989 to 2021), specifically on Pakistan, with respect to family planning services utilization, have found that the use of family planning services was an outcome of a woman’s education, awareness status, wealth or economic status, religion, husband’s approval, area of residence, number of living children, prevalence of the desired family planning method, desire for more children, subsidized healthcare services and other social or individual factors. In Pakistan, the average contraceptive use rate was recorded as between 19-49 percent across the regions and between 0-71 percent across the districts. The region Islamabad Capital Territory (ICT) had the highest contraceptive usage rate, i.e., 49%, followed by: Punjab (42%), Khyber Pakhtunkhwa (KPK) and Gilgit Baltistan (39% each), Sindh and Azad Jammu and Kashmir (AJK) (34% each), Federally Administered Tribal Areas (FATA) (24%), and Balochistan (19%). Amongst the districts, top three districts with highest contraceptive usage were Jafarabad, Sheikhupura and Jhang whereas the districts of Rajanpur, Tor Ghar and Kohlu were lying at the bottom. Region-wise disaggregation found that in the province of Punjab and Sindh, the range of contraceptive use across the districts was respectively ranged between 0-70 percent and 8-60 percent. Likewise, in KPK and Balochistan provinces, the range of contraceptive use had been recorded between 0-59 percent and between 2-71 percent. While the range of contraceptive use in Gilgit-Baltistan, FATA region, and in AJK had been respectively recorded between 9-48 percent, 11-39 percent, and 17-47 percent.

Moisture Content and Aromatic Compounds Determination in Transformer Oil Using Spectral Method
Authors:   Kazan State Power Engineering University, Russian Federation, Kozlov Vladimir , Kurakina Olga ,   Kazan State Power Engineering University, Russian Federation
Published: July 2022

During operation, resulting from the thermochemical and electrical effects, the performance of the transformer oil decreases due to the measurement of the structural group composition. An increase in the content of the aromatic hydrocarbons leads to the appearance of a precipitate, and as well as due to its hygroscopicity, an increase in the moisture content. The latter is one of the transformer oil parameters that determines its quality. In power equipment, the presence of moisture of the order of 10 grams of water per ton of oil is allowed. At elevated water concentrations, there is a risk of the power transformers’ failure. The aim of the work was to develop new methods for determining the aromatic compounds and water contents in the transformer oil in small quantities. This goal was achieved by conducting spectral studies of the transformer oil samples in the UV range and constructing correlation lines to determine the moisture content and concentration of aromatic compounds. The most significant result of the article was the establishment of correlations between the optical density of the transformer oil in the region of 530 nm and the concentration of aromatic compounds and between the optical density in the region of 980 nm and moisture content in the oil. The significance of the obtained results lies in the fact that the optical method for determining the moisture content and aromatic hydrocarbons in transformer oils, using the constructed correlation lines, is highly accurate and does not require the use of additional reagents and complex calculations.

Published: July 2022

Forecasting electricity tariff rates is necessary for large suppliers, consumers, and power brokers working in the wholesale markets. Meanwhile, tariff rates of the retail market are also hourly changed for certain groups of electricity consumers. It creates more efficient electrical load regulation opportunities than the traditional load leveling approach. Power facilities that include controlled load consumers or local generation can use their capabilities by adjusting the load curve according to tariff rates. This work aims to study the potential for medium-term forecasting of retail electricity tariff rates and develop a predictive machine learning model. Hourly data on the retail market tariffs of the Novosibirsk region (Siberia) for four years were collected, several machine learning models were applied, and an analysis of the input parameters for forecasting was carried out. The most significant results are the proof of the possibility of obtaining the month ahead electricity tariff rate forecast with the mean absolute percentage error 4 %. It could be used for electricity costs reduction by regulating the load curve. It was shown that the discrete models based on ensembles of logical rules give higher accuracy than models based on continuous and piecewise continuous functions, such as neural networks. The significance of the obtained results is the proposed approach for month ahead electricity tariff rates forecasting, which was verified on a four-year dataset with an error of 4 %. The approach is based on open data and open-source machine learning models, which allow specialists with even a basic level of data science skills to put it into practice.

Authors:   National University of Intellectual Technologies and Communications, Ukraine, Stopakevich Andrey , Stopakevich Alexey ,   Odessа Polytechnic National University, Ukraine
Published: July 2022

This paper is devoted to the development of a decentralized control system design method with improved robustness, applicable to distillation columns control problem. The aim is attained by solving the following tasks: selection of representative models of columns; development of an effective transfer function identification algorithm; development of a decentralized controller design algorithm, which takes into account the cross-links impact; verification of the developed method for the selected models of columns. The most important result is the developed design method, which includes two algorithms. The first algorithm can be used to identify simplified models of the effective transfer functions. The second algorithm makes it possible to design a decentralized control system based on the ratio between the diagonals of the original model and effective transfer functions. Modified PI controller is used. The achievement of the distillation column control system robustness to the synchronous technologically conditioned deviation of the model parameters by up to three hundred percent of the nominal value is the paper significant result. The digital implementation of the designed controllers is simple. The analysis of the literature shows that none of the previously proposed methods for designing decentralized automatic control systems solved such a problem. The efficiency of the developed algorithms is illustrated using the known models of dynamics of distillation columns. The analysis of limitations of the method as well as its significant differences to the Biggest Log Tuning and H∞ loop shaping methods is presented.

The work is devoted to control systems for hybrid heat pumps using the heat of return network water and outside air, designed to operate in district heating systems based on CHPP. The aim of the research is to develop control systems for heat pump operating on qualitative, quantitative and quantitative-qualitative heat schedules. The set goal is achieved by introducing two controlled heat exchangers: one of "refrigerant-water" type, installed after the evaporator and "refrigerant-air" type, installed after the gas cooler. The most important results are the hydraulic scheme of the heat pump, the control system scheme of gas superheater installed after the evaporator and gas supercooler installed after the gas cooler. The significance of the obtained results consists in obtaining a technical solution, which ensures the operation of the heat pump at different heating schedules. Equations of heat pump apparatuses have been obtained, in which the influence of flow rate and temperature of the working body on the heat pump operating mode is emphasized. The obtained heat balance equations allowed obtaining structures of automatic control systems for heat exchange apparatuses, compressors and controlling valves of the hybrid heat pump. The developed scheme of the heat pump air duct allowed using a minimum of heat of return network water in the heat pump. It has been established that the scheme of this automatic control system should include a functional converter linking the temperature of the outside air and the coordinates of the working body state at the outlet of the gas subcooler.

Published: July 2022

Customer satisfaction is an effort to fulfill customer needs and demand as well as to fulfill the provisions concerning its realization to balance customer expectation, and it is vital as it benefits the company. However, customers are dissatisfied at times with products or services provided by companies resulting in complaints. Public complaining is a medium used by customers to express their dissatisfaction with the use of product and services. It is made by customers who expect improvements for service failures. Public complaining is formed from identity, in handling complaints, companies take an action called service recovery as service provider to resolve service failures.
