The Role of Interstitial Solid Solutions in the Formation of Active Component in Supported Palladium Catalysts for Selective Hydrogenation of Acetylene to Ethylene
Authors: Shlyapin D. A. , Glyzdova D. V. , Afonasenko T. N. , Temerev V. L. , Lavrenov A. V.
Published: December 2022

The effect of adsorption of the reaction medium components on selective hydrogenation of acetylene to ethylene under the action of supported palladium catalysts is considered. The role of interstitial solid solutions of carbon and hydrogen in palladium, which are formed upon contact of the catalyst with the reaction medium, in the mass-transfer processes between surface and subsurface layer of the active component is revealed. The ratio of activation barriers for ethylene desorption/adsorption processes, which determines the selectivity of acetylene hydrogenation, can change in dependence on the structure of palladium nanoparticles and its electronic state. Therewith, changes in the electronic state affect the energy of activated desorption of ethylene from palladium particles, and their structural features determine the energy of activated adsorption and the subsequent hydrogenation of ethylene to ethane.
French poems of Nikolay Gumilyov
Authors:   Lomonosov Moscow State University, Belavina Ekaterina M.
Published: December 2022

Paris, regarded for centuries as the literary capital of the world, the literary ‘homeland of choice’, gave shelter (permanently or temporarily) to many great writers. Poets all over the world have dreamed of gaining access to the French reader; it has tacitly been considered a special stepping stone to global recognition. At the turn of the nineteenth and twentieth centuries, the paths of many Russian poets crossed in Paris. It was there that Gumilyov met A. Tolstoy, M. Voloshin, A. Bely and others. Most of his poems were written in his native language and translated from the foreign language into the native language. A rare case of cultural transfer and cross-linguistic contact are poetic texts written by the author in a foreign language, based on the original in his native language (auto-translation from the native language), or subsequently written in his native language (auto-translation from a foreign language). The auto-translations by Nikolai Gumilyov (1886–1921) did not have a resonance and his name is not very familiar to the French reader. The few translations done by the French have appeared in anthologies, and the first book of selected poems was published in France in the twenty-first century. Gumilyov’s rhyming poems were not well-received at a time when vers libre standard was being developed in France. The linguistic roughness of the form, striving for the classical form, gave the impression of linguistic errors. Gumilyov’s innovation manifested itself in overcoming national and temporal boundaries. A later fondness for the history of French literature manifested itself in programmatic focus of manifestos on tradition, which ran counter to Parisian contemporaries who deviated from laws of “beautiful clarity”. The desire to convey the music of the Russian syllabo-tonic also did not favour publications in French. Gumilev’s reception in France was delayed in time.
Kelam’ın Terimleştirdiği Bir Kur’an Kavramı Şefaat
Authors: ATILGAN Yusuf Kenan
Published: December 2022

Şefaat kelimesi Kur’an’da on dokuz surede otuz bir defa geçmektedir. Lügatte “aracı olmak, yardımcı olmak, vesile olmak, tek olan bir şeyin çift olması” gibi anlamlara gelmektedir. Istılah olarak ta, “ahirette günahkâr mü’minlerin günahlarının bağışlanması, günahı olmayanların da derecelerinin yükseltilmesi için Hz. Peygamber’in Allah katında dua etmesi, yalvarması ve onlara yardımcı olmasıdır.” Kur’an’da şefaatin yer aldığı ayetler, bir kısmı şefaatin olmadığı bir kısmı ise Allah’ın dilemesiyle şefaatin olacağı şeklinde tasnif edilmektedir. İlgili ayetlere dayanarak bazı mezhep ya da âlimler ile yine tefsir ve kelam gibi farklı alanlarda çalışma yapan araştırmacılar farklı sonuçlara ulaşmaktadırlar. Konuyu, bütün ön kabulleri bir kenara bırakıp vahyin nüzul sürecini dikkate alarak mekki-medeni ayetler bağlamında siyak-sibak ilişkisi ve Kur’an’ın Kur’an ile tefsirini öncelemek suretiyle incelediğimiz zaman şefaatin sadece Allah’a ait olduğu sonucunun daha makul olduğu anlaşılmaktadır. Çalışmada asıl maksat hicri I. yy.’da tartışılmaya başlanan kavramın hicri II. yy.’a ulaşıldığında artık kelami bir terim halini aldığının tespit edilmesidir.

Published: December 2022

BACKGROUND: Intestinal microbial dysbiosis and its metabolites can affect the immune activity of intestinal mucosal cells, causing insulitis and pancreatic β-cell death. Probiotic Lactobacillus acidophilus plays an important role in reducing inflammatory cytokines, hence improves oxidative stress that affects pancreatic β-cell apoptosis. Current study examined the feature of pancreatic histopathology affected by the administration of probiotic L. acidophilus in rats with type-1 diabetes mellitus (DM) induced by streptozotocin (STZ).METHODS: Twelve rats were induced by STZ at double dose of 50 mg/kgBB before administered with probiotic L. acidophilus at a dose of 1.5x10 8 or 1.5x10 9 CFU/mL/day, while other 4 rats were used as control. After 21 days of the L. acidophilus treatment, the average of fasting blood glucose (FBG) levels of rats were measured, then the pancreatic histopathology was assessed to evaluate the degree of insulitis in islet of Langerhans.RESULTS: The induction of STZ had been succeeded to increase blood glucose levels, which indicate DM condition. The highest FBG level after 21 days of treatment was found in DM group with glucose level of 512±81.51 mg/dL. The administration of probiotic L. acidophilus during 21 days treatment at both dose 1.5x10 8 and 1.5x10 9 CFU/mL/day significantly improved pancreatic histopathology (p=0.04 and p=0.034, respectively), with significant decrease on insulitis scores compared to DM group.CONCLUSION: The administration of L. acidophilus at both dose of 1.5x10 8 and 1.5x10 9 CFU/mL/day for 21 days can improve pancreatic histopathology of type-1 DM rats induced by STZ, therefore probiotic L. acidophilus may be potential as supplementation treatment for type-1 DM.KEYWORDS: Lactobacillus acidophilus, pancreatic histopathology, streptozotocin, type-1 diabetes mellitus

The purpose of this study is to examine the relationship between sustained general well-being and quality education experienced by faculty members in private universities. Particularly, how do managerial practices, such as faculty compensation, job security, job autonomy and faculty promotion opportunity, affect quality education mediated by faculty well-being? To answer this question, a theoretical framework using the effort–reward imbalance (ERI) model as its basis was established. Using measurement scales, a survey instrument was developed to test the various relationships implied by the ERI model. Data (n = 515) were collected from faculty members of private universities in Bangladesh in 2019. Structural equation modelling was followed to analyse the data. The findings of the study indicate that faculty well-being has a significant direct and mediating role to influence quality education in private universities in Bangladesh.

Authors: Al-Hendawi Maha
Published: December 2022

Identifying factors that affect emotional and behavioral difficulties in adolescents is crucial for ameliorating these conditions and their negative impact as well as reducing the prevalence of these disorders. Self-esteem and school adjustment are two crucial but understudied factors that may significantly influence adolescents' sense of self and propensity to behavioral problems. In this study, 519 adolescents were examined for self-esteem and school adjustment in relation to emotional and behavioral difficulties, using the Rosenberg Self-Esteem Scale, School Adjustment Scale, and Strengths and Difficulties Questionnaire. The majority of students in this study had average or high self-esteem. Multiple regression analysis revealed significant relationships between self-esteem, school adjustment, and behavioral disorders. Furthermore, path analysis showed that school adjustment mediated the association between self-esteem and behavioral problems.

The Eat, Sleep, Console Method: A Literature Review
Authors: Nicholson Sarah , Waskosky Aksana
Published: December 2022

Neonatal abstinence syndrome (NAS) is a significant public health problem in the United States. The most commonly used tool to assess and treat infants with NAS is the Finnegan Neonatal Abstinence Scoring System (FNASS). The more recently developed Eat, Sleep, Console (ESC) method simplifies assessment of NAS. Current research suggests promising outcomes with the ESC method in areas such as length of hospital stay (LOS) and amount of medication needed to treat NAS. A literature review was conducted to answer the following question: In newborn infants with NAS born at 36 weeks of gestation or older, does the ESC method reduce the use of medication and LOS when compared with the FNASS? All of the studies reporting on LOS and medication usage rates reported a decrease in both when moving to the ESC method from FNASS.

Published: December 2022

Les briques de terre stabilisées peuvent être une bonne alternative pour résoudre le problème de logement si les typologies de sol, les horizons de prélèvement de sol et les quantités de liants bon marché comme la paille de riz sont identifiés. Une étude a été réalisée sur les sols prélevés dans l’horizon B de Ferralsols et d’Acrisols ainsi que sur un échantillon de Kaolin ont été utilisés pour les fabrications d’adobe. Les briques de terre crue ont été fabriquées avec différentes proportions de paille de riz (0,2% ; 0,4% ; 0,6% ; 0,8% et 1%) et soumises à des tests de compressibilité et de flexion. Les résultats obtenus montrent que le dosage à 0,4% de paille a été optimal, avec une résistance à la compression de 1,04 - 1,2 N/mm2 pour les Ferrasols prélevés à une profondeur de 113 cm -30 m et 0,21- 0,65N/mm2 pour les Acrisols (74 -122 cm). La proportion optimale de paille était 0,2% pour la flexion (0,01 - 0,06N/mm2) avec une valeur plus élevée (0,06 N/mm2) pour le kaolin issu du Ferralsol plinthic, justifiant cette recommandation pour une meilleure résistance à la flexion. Le Ferrasol Stagnic dosé à 0,4% de paille peut être recommandé pour une meilleure résistance des briques à la compression.

The bricks of soil stabilized may constitute a promising alternative to solve the problem of housing provided that the typologies of soil, sampling horizons and quantities of cheap bonds like rice straw are identified. This study was carried out on the soil samples collected from the B horizon of Ferralsols and Acrisols, as well as on a sample of Kaolin used to manufacture Adobe. Mud bricks were made with different proportion of rice straw (0.2% ; 0.4% ; 0.6% ; 0.8% and 1%), and subjected to compressibility and flexion tests. The results showed that the 0.4% straw backing is optimal, it gives a compressive strength of 1.04 – 1.2 for Ferralsols collected at the depth of 113 cm - 30 m and 0.21 – 0.65N/mm2 in Acrisols (74 - 122 cm). The optimal straw proportion was 0.2% for Kaolin from Ferrasol Plinthic, supporting this recommendation for bending resistance. Ferrasol Plinthic with 0.4% straw may be recommended for a better resistance of the bricks to compression.

Immigrant-Serving Organizations and Local Law Enforcement: Do Nonprofits Predict Cooperation with ICE?
Authors: Chand Daniel E. , Calderon M. Apolonia , Hawes Daniel P.
Published: December 2022

Relatively little research has examined the role of immigrant-serving organizations (ISOs) as policy advocates, and virtually no studies have sought to empirically determine whether ISOs shape local policy implementation decisions. Here we study the relationship between ISOs and the policy decisions of sheriff offices, which oversee county jails. Sheriff offices are vital to implementing federal immigration enforcement programs. We determine whether the presence of ISOs predicts sheriff office cooperation with Immigration and Customs Enforcement (ICE). Using a sample of 630 sheriff offices that responded to a national U.S. Bureau of Justice survey, we find the concentration of ISOs registered to provide pro bono legal aid in immigration court does predict sheriff office cooperation. The presence of these legal-aid nonprofits predicts whether sheriff offices will adopt anti-detainer (or ‘sanctuary’) policies. Additionally, these legal-aid nonprofits also correspond to fewer immigration background checks submitted to ICE from county jails.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections have triggered a recent pandemic of respiratory disease and affected almost every country all over the world. A large amount of natural bioactive compounds is under clinical investigation for various diseas-es. Especially, marine natural compounds are gaining more attention in the new drug develop-ment process. The present study has aimed to identify potential marine-derived inhibitors against the target proteins of COVID-19 using a computational approach. Currently, 16 marine clinical-level compounds were selected for computational screening against the four SARS-CoV-2 main proteases. Computational screening resulted from the best drug candidates for each target based on the binding affinity scores and amino acid interactions. Among these, five marine-derived compounds namely Chrysophaentin A (-6.6 kcal/mol), Geodisterol sulfates (-6.6 kcal/mol), Hymenidin (-6.4 kcal/mol), Plinabulin (-6.4 kcal/mol) and Tetrodotoxin (-6.3 kcal/mol) expressed the minimized binding energy and molecular interactions such as covalent and hydrophobic interactions to the SARS CoV-2 Main Protease. Using Molecular dynamic stud-ies, the Root-Mean-Square Deviation (RMSD), Root-Mean-Square Fluctuation (RMSF), Radius of Gyration (ROG), and Hydrogen bonds (H-Bonds) values were calculated for SARS-CoV-2 Main Protease with Hymenidin docked complex. Additionally, in silico Druglikeness and pharmaco-kinetic property assessments of the compounds demonstrated favorable druggability. These re-sults suggested that marine natural compounds are capable of fighting SARS-CoV-2. Further, in vitro and in vivo studies need to be carried out to confirm their inhibitory potential.
Efficient Anomaly Heartbeat Detection Approach for Intermediate Nodes of Internet‐of‐Things Platforms
Authors: Ramirez Lopez Leonardo Juan
Published: December 2022

This work focused on the evaluation of some machine learning (ML) models and their application in e-health, using intermediate nodes within an Internet of Things (IoT) platform used for heartbeat anomaly detection. For the evaluation of ML models, a set of statistical validation metrics was selected. These metrics were applied in the training, testing and validation phases of the models. The results obtained can determine relevant factors for the selection of ML models, either based on the statistical and intrinsic efficiency of the ML models, or on their suitability to be implemented in intermediate nodes within an IoT platform. the more Lightweight models such as Simple Linear Regression, Logistic Regression, and K Nearest Neighbors, could easily operate in intermediate nodes, and they are models that require low processing and storage to work. In conclusion, the approach for intermediate nodes of Internet of Things platforms using cognitive networks decreases the processing cost in cloud computing and transfers it to the fog layer.
Nonoperative Versus Operative Treatment for Displaced Finger Metacarpal Shaft Fractures
Authors: Peyronson Fredrik , Ostwald Cecilia Stalberg , Hailer Nils P. , Giddins Grey , Vedung Torbjörn , Muder Daniel
Published: December 2022

Update

This article was updated on January 18, 2023, because of a previous error, which was discovered after the preliminary version of the article was posted online. On page 103, in the first column of Table III, the continuous outcomes, which had been given as “Median” and “(range)”, are now given as “Mean” and “(95% CI)”, respectively.

Background:

Finger metacarpal fractures represent up to 31% of all hand fractures, and most can be treated nonoperatively. Whether operative treatment is superior to nonoperative treatment for oblique and/or spiral finger metacarpal shaft fractures (MSFs) is unknown.

Methods:

Forty-two patients with displaced oblique and/or spiral finger MSFs were randomized to either nonoperative treatment with unrestricted mobilization or operative treatment with screw fixation. The primary outcome was grip strength in the injured hand compared with the uninjured hand at the 1-year follow-up. Secondary outcomes were the Disabilities of the Arm, Shoulder and Hand score, range of motion, metacarpal shortening, complications, sick leave duration, patient satisfaction, and costs.

Results:

All patients attended the 1-year follow-up. Mean grip strength relative to that in the contralateral hand was 104% (95% confidence interval [CI], 89% to 120%) in the nonoperative group and 96% (95% CI, 89% to 103%) in the operative group (p = 0.34). Mean metacarpal shortening was 5.3 mm (95% CI, 4.2 to 6.4 mm) in the nonoperative group and 2.3 mm (95% CI, 0.8 to 3.9 mm) in the operative group. In the nonoperative group, 1 minor complication was observed; in the operative group, there were 4 minor complications and 3 reoperations. The costs were estimated at 1,347 U.S. dollars (USD) for nonoperative treatment compared with 3,834 USD for operative treatment. Sick leave duration was significantly shorter in the nonoperative group (12 days [95% CI, 5 to 21 days] versus 35 days [95% CI, 20 to 54 days]) (p = 0.008).

Conclusions:

When treated with unrestricted mobilization, patients with a single displaced spiral and/or oblique finger MSF have outcomes comparable to those treated operatively, despite metacarpal shortening. Costs are substantially higher (2.8 times) and sick leave is significantly higher in the operative group.

Level of Evidence:

Therapeutic Level II. See Instructions for Authors for a complete description of levels of evidence.

Introduction: Emotional intelligence is defined as the ability to manage emotions effectively. It has a clear impact on the well-being of schoolchildren. A large body of studies has shown how emotional intelligence impacts on psychological and contextual variables, but less is known about how school context may influence in emotional development during childhood. The objectives of this research were to describe the level of emotional intelligence and school climate for schoolchildren in Primary Education in three European countries, to explore the association between school climate and emotional intelligence, and analyzing the moderating role of gender and country. Method: 1104 schoolchildren participated (528 from Spain, 252 from Poland and 324 from Norway) (50.6% girls; MAge = 10.49 years; SD = 1.3). Validated self-report in the three languages were used, Trait Meta-Mood Scale-24 and Modified-Delaware School Climate Survey-Student. Results: Descriptive analysis showed higher levels of emotional intelligence in Spanish schoolchildren and higher level of school climate. Girls showed higher levels of emotional repair compared to boys. Multiple multivariate regression models indicated the association between school climate and emotional intelligence  . Gender and country did not moderate the relationship between school climate and emotional intelligence dimensions. Conclusions: This study highlights the importance of the quality of the climate in schools in different European regions to promote the level of emotional intelligence of boys and girls in Primary Education.
Facilitating Access to Healthcare for Performing Artists Using Subsidized Health Services in Canada: An Interpretive Descriptive Study
Authors: Li Shelly-Anne , Donn Gemma
Published: December 2022

BACKGROUND: Performing artists are often confronted with job insecurity and insufficient health coverage. As a result, artists may not have access to non-publicly funded health services that are essential to their well-being. A health centre in Canada that specializes in providing healthcare
to artists offers eligible artists subsidized health services, with the aim to treat acute health issues that impact an artists’ ability to engage in their artistic practice. PURPOSE: We evaluated the use of the subsidized health services and explored the subsidy recipients’ and
the selection committee’s perspectives on the impact of these services on the health of performing artists. METHODS: We applied an interpretive descriptive approach to our qualitative inquiry. We conducted individual, semi-structured interviews with recipients of the subsidy and a focus
group with the selection committee that selected recipients of the subsidy. Data were analyzed using thematic analysis. RESULTS: A total of 14 artists and all members of the selection committee (n=3) participated. Recipients and selection committee perceived that subsidized health services
were critical in enabling consistent and timely diagnosis and treatment. Several themes emerged from the data: 1) need for universal health benefits to restore equity and offset healthcare insecurity, 2) the critical role of subsidies in accessing health services, 3) risks of abruptly ending
health services when subsidy runs out, 4) barriers in applying for and accessing subsidies, 5) mental health challenges, and 6) importance of the subsidy in the context of the COVID-19 pandemic. All recipients saw noticeable improvement in health outcomes that they believed would have been
otherwise unattainable if they did not have timely access to care. CONCLUSIONS: Subsidized health services play an important role in ensuring that performing artists have access to care for injuries and health conditions that are related to their profession. Future research can examine the
long-term impact of subsidized services on the recipients’ health and employment outcomes.
Are Factors of Posture and Balance Integrated in Research Studies on Upper Extremity Musculoskeletal Pain in Instrumental Musicians?: A Scoping Review
Authors: Garnett Ron , Pijl Em M. , Visentin Peter
Published: December 2022

It is widely believed that posture and balance stressors are factors in playing-related pain for musicians using hand-held musical instruments. This purpose of this scoping review was to assess the available literature relative to the effects of posture and balance in musicians with
neuromusculoskeletal injuries. A search of Medline, Web of Science, and SportDiscus seeking articles combining posture and balance considerations with pain in performing artists was performed. From 1,403 articles initially identified by the search parameters, the further abstract/title review
for relevance and inclusiveness of pain and posture/balance variables in performing artists resulted in the retention of 29 articles for this full-text scoping review. The full-text analysis assessed publication type, study design, participant population, methodology, statistical methods,
main results, and whether the study evaluated the relationship between posture/balance and pain in musicians. Overall, most of the studies including musicians were observational or descriptive. Although, in recent years, there has been an increase in the number of interventional studies regarding
posture, balance and pain in musicians, there is still minimal evidence about the contribution of posture and balance characteristics to pain in musician performers. To reliably establish a predictable relationship with injury symptomatology experienced by musicians, it is essential to integrate
standardized, validated measurements of posture and balance in the evaluation of all musicians who report to a health professional with neuromusculoskeletal pain. This will not only allow researchers to determine the effect of postural righting dysfunction on neuromusculoskeletal injuries
in musicians, but also may provide a foundation for clinicians to develop effective interventions.

Resistance training is considered the most effective intervention for increasing older people’s muscle mass and strength. We devised a self-administered training system (squat + balance training, sukubara®) that incorporates a new low-load exercise. This study hypothesizes that introducing sukubara® affects skeletal muscle mass and physical function positively. A preliminary verification was conducted in healthy non-elderly participants comprising hospital personnel. Participants were randomly assigned to two groups, a resistance training group that performed an exercise program (sukubara®) and a control group that did not, and they received a 12-week intervention. This study’s primary endpoint was a change in skeletal muscle mass; the secondary endpoints were knee extension strength and one-leg standing time with eyes closed. An analysis of the 18 participants (8 in the resistance training group and 10 in the control group) was performed. Results showed that skeletal muscle mass, knee extension strength, and one-leg standing time were significantly improved or tended to be significantly higher in the resistance training group than in the control group. Our study concluded that the self-administered training system (sukubara®) incorporating low-load exercise resulted in muscle hypertrophy and improvement in physical function.
Simultaneous transmission of hyper-entanglement in 3 degrees of freedom through a multicore fiber

Entanglement distribution is at the heart of most quantum communication protocols. Inevitable loss of photons along quantum channels is a major obstacle for distributing entangled photons over long distances, as the no-cloning theorem forbids the information to simply be amplified along the way as is done in classical communication. It is therefore desirable for every successfully transmitted photon pair to carry as much entanglement as possible. Spontaneous parametric down-conversion (SPDC) creates photons entangled in multiple high-dimensional degrees of freedom simultaneously, often referred to as hyper-entanglement. In this work, we use a multicore fibre (MCF) to show that energy-time and polarization degrees of freedom can simultaneously be transmitted in multiple fibre cores, even maintaining path entanglement across the cores. We verify a fidelity to the ideal Bell state of at least 95$\%$ in all degrees of freedom. Furthermore, because the entangled photons are created with a center wavelength of 1560 nm, our approach can readily be integrated into modern telecommunication infrastructure, thus paving the way for high-rate quantum key distribution and many other entanglement-based quantum communication protocols.

Published: December 2022

The human monkeypox virus (MPVX) was first identified in 1959. Since then, the incidence of the disease has been sporadic. The endemic regions were identified in Africa's central and western areas. However, the infection started to spread in 2017 to the non-endemic regions such as North and South America, Europe, and Asia. Since May 2022, the non-endemic areas reported 62,635 till 20th September 2022. Although the monkeypox virus has a mortality of ≥ 10%, it showed only 82 mortalities worldwide in 2022. The common symptoms include chills, fever, fatigue, and skin lesions, and the complications include secondary respiratory tract infections, encephalitis, blindness, and severe diarrhoea. The factors responsible for spreading the virus include improper handling and consumption of infected bushmeat, unprotected sexual intercourse, contact with an infected person, no smallpox vaccination, improper hygiene, lower diagnostic capacity, and strong travel history from the endemic regions. The therapeutic strategy is symptom-based treatment and supportive care. Antivirals and vaccines such as Tecovirimat, Brincidofovir, Cidofovir, Imvamune, and ACAM2000 have shown promising results. The primary purpose of the review is to perform an epidemiological study and investigate the pathobiology, diagnosis, prevention, treatment, and some associated complications of the monkeypox virus in 2022.
Hysteroscopy assisted suction curettage for early pregnancy loss: Does it reduce retained products of conception and postoperative intrauterine adhesions?
Authors: MOORE OMER , Tzur Tamar , Vaknin Zvi
Published: December 2022

Objective: To describe the feasibility of hysteroscopy assisted suction curettage for early pregnancy loss and to investigate whether it reduces the rates of retained products of conception (RPOC) and intrauterine adhesions (IUA).
Design: Prospective single-arm cohort study.
Setting: University-affiliated department of Obstetrics and Gynecology.
Patients: Women admitted for surgical evacuation in cases of early pregnancy loss were offered participation in the study.
Intervention: Vaginal misoprostol was administered for cervical ripening preoperatively. Under general anesthesia, a diagnostic hysteroscopy was performed to identify the pregnancy’s implantation wall, followed by ultrasound guided suction and curettage directed to the implantation wall, and diagnostic hysteroscopy to verify complete uterine cavity emptying. Postoperative IUA were evaluated by follow-up office hysteroscopy.
Main Outcome Measure: Identification of the pregnancy’s implantation wall on hysteroscopy, and intra- and postoperative complications associated with the procedure. The evaluation of postoperative IUA was limited due to the COVID-19 pandemic and restrictions on elective procedures.
Results: 40 patients were included in the study group. Their mean age was 34.0 ± 6.6 years, and their mean gestational age was 8.9 ± 1.6 weeks. In 33 out of 40 cases (82.5%), the implantation wall was clearly visualized on hysteroscopy. The mean operative time was 17.2 ± 8.8 minutes, and no intraoperative complications occurred. In 4 cases, suspected RPOC were diagnosed intraoperatively by hysteroscopy and removed. The histology examination confirmed the presence of RPOC in 3 out of these 4 suspected RPOC cases. Follow-up office hysteroscopy was performed in 9 women, diagnosing mild IUA in one case and a normal cavity in 8 cases. In 15 cases, a new pregnancy was reported at time of follow-up, while 12 women declined to attend the follow up-hysteroscopy and 4 were lost to follow-up.
Conclusions: Hysteroscopy assisted suction curettage for early pregnancy loss is a safe, short, and inexpensive procedure, which allows the identification of the pregnancy’s wall in most cases and may reduce the rates of RPOC and IUA.
