Background: Prolonged skin exposure to ultraviolet light rays leads to photoaging, which is characterized molecularly by an increase in reactive oxygen species (ROS), cell apoptosis, and a decrease in collagen. Photoaging therapy has been a challenge until recently. Fibroblasts exposed to ultraviolet B (UVB) light proved to be a good model for photoaging skin. They are also the primary dermal cells that stimulate collagen production and extracellular matrix (ECM), which contribute to skin aging. Exo-HUVEC is rich in growth factors, cytokines, and miRNAs, and they all play a vital role in cell-to-cell communication. The migration of fibroblasts is crucial for the development, repair, and regeneration of skin tissue during the repair of skin aging.
Objective: An in vitro experimental study was conducted to analyze the effect of Exo-HUVEC on oxidative stress levels, cell apoptosis, and fibroblast migration rate after UVB ray exposure on fibroblasts.
Methods: The fibroblast cultures were divided into five groups, including one without UVB exposure, one with UVB exposure, and one with UVB+Exo-HUVEC exposure at 0.1%, 0.5%, and 1%, respectively. Oxidative stress levels were measured using the ELISA test for malondialdehyde (MDA). Furthermore, flow cytometry was used to measure apoptosis using PI/Annexin markers, while a scratch assay examination was used to measure fibroblast migration rate using imaging readings.
Results: There were significant differences in the levels of MDA, PI/Annexin, and the rate of fibroblast migration between the UVB-irradiated control group and the Exo-HUVEC treatment group (p<0.001).
Conclusion: Exo-HUVEC is a marker of photoaging improvement, which has anti-apoptotic effects and reduces oxidative stress, as well as increases fibroblast migration rate.

Authors: Zhang Xin , Kim Kyung-Won , Kim Young-Hyo
Published: August 2022

Two dexaminid amphipod species belonging to the genus Paradexamine were collected from Korean waters. After observation and identification compared with related congeners, these two species are revealed to be new to science. In comparative identification, one of the new species, P. acutasp. nov. is similar to P. houtete in having an acutely rounded lobe and posteroventrally pointed coxa 7. However, this new species is distinguished from P. houtete in having a larger number of medial setae on the propodus of gnathopod 1 and a rounded basis of pereopod 6. This new species is also very similar to P. marlie s.l. Hirayama from Japanese waters, and P. marlie s.l. might be re-established or synonymized with P. acutasp. nov. in the future. The other new species, P. rotundogenasp. nov. is similar to P. tafunsaka in having a rounded eye lobe; however, it is distinguished from P. tafunsaka in having an elongate carpus on gnathopod 2 and the differently shaped basis of pereopod 7. A key to the five Korean species of Paradexamine, including the two new species, is also provided.

Published: August 2022

The global burden of illegal drug-related death and disability continues to be a public health threat in developed and developing countries. Hence, a fractional-order mathematical modeling approach is presented in this study to examine the consequences of illegal drug usage in the community. Based on epidemiological principles, the transmission mechanism is the social interaction between susceptible and illegal drug users. A pandemic threshold value ($ \Lambda $) is provided for the illegal drug-using profession, which determines the stability of the model. The Lyapunov function is employed to determine the stability conditions of illegal drug addiction equilibrium point of society. Finally, the proposed model has been extended to include time lag in the delayed illegal drug transmission model. The characteristic equation of the endemic equilibrium establishes a set of appropriate conditions for ensuring local stability and the development of a Hopf bifurcation of the model. Finally, numerical simulations are performed to support the analytical results.

Published: August 2022

One of the most famous equations that are widely used in various branches of physics, mathematics, financial markets, etc. is the Langevin equation. In this work, we investigate the existence of the solution for two generalized fractional hybrid Langevin equations under different boundary conditions. For this purpose, the problem of the existence of a solution will become the problem of finding a fixed point for an operator defined in the Banach space. To achieve the result, one of the recent fixed point techniques, namely the $ \alpha $-$ \psi $-contraction technique, will be used. We provide sufficient conditions to use this type of contraction in our main theorems. In the calculations of the auxiliary lemmas that we present, the Mittag-Leffler function plays a fundamental role. The fractional derivative operators used are of the Caputo type. Two examples are provided to demonstrate the validity of the obtained theorems. Also, some figures and a table are presented to illustrate the results.

Published: August 2022

Fresh fishery products are highly perishable foods mainly due to their high-water content and high level of pH which act as promoters of spoilage processes. In these matrices, the deterioration phenomena are the result of the action of oxidative, and enzymatic processes due in part to the presence of specific microorganisms. Indeed, the microbial communities responsible for spoilage are a small fraction of the flora detectable in the fish and are known as specific spoilage organisms (SSOs). In the last decades, the scientific community has worked to achieve the ambitious goal of reducing the impact of microbial deterioration on food losses through innovative solutions, including antimicrobial packaging. The goal of this study was to evaluate the efficacy of an active polypropylene (PP)- based packaging functionalized with the antimicrobial peptide 1018K6 to extend the shelf life of dolphinfish burgers (Coryphaena hippurus) by evaluating its effect on sensorial and microbiological profile. The microbiological results showed an evident antimicrobial activity of the active packaging against hygiene indicator microorganisms and SSOs, recording a reduction of about 1 Log (CFU/g) of their concentrations compared to those of the control groups. Furthermore, a significant influence of functionalized packaging on the organoleptic characteristics was noted, accentuating the differences in freshness between the two experimental groups. This work confirmed the hypothesis of considering antimicrobial packaging as a potential tool capable of slowing down surface microbial replication and, therefore, extending the shelf-life and improving the health and hygiene aspect of fresh fish products.

Authors: Han Xue , Hu Zuojin , Wang William
Published: August 2022

In recent years, COVID-19 has spread rapidly among humans. Chest CT is an effective means of diagnosing COVID-19. However, the diagnosis of CT images still depends on the doctor's visual judgment and medical experience. This takes a certain amount of time and may lead to misjudgment. In this paper, a new algorithm for automatic diagnosis of COVID-19 based on chest CT image data was proposed. The algorithm comprehensively uses WE to extract image features, uses ELM for training, and finally passes k-fold CV validation. After evaluating and detecting performance on 296 chest CT images, our proposed method is superior to state-of-the-art approaches in terms of sensitivity, specificity, precision, accuracy, F1, MCC and FMI.
Combination of catalytic ozonation and fungal bioremediation for treatment from effluent from the laminate production industry
Authors: Scherer Claudio Eduardo , Barreto-Rodrigues Marcio
Published: August 2022

This study characterized and evaluated the potential of a combination of treatment strategies for the removal of phenolic compounds, color, and ecotoxicity of an effluent generated by a laminated wood industry. The characterization of a sample of the effluent generated by the pine lamination process collected in an industry in the Southwest region of the state of Paraná confirmed the potential impact of the effluent, with emphasis on the high content of phenolic compounds (1,530 ±50 mg/L), color (2,159 ±30 units), significant acute toxicity (63% mortality of microcrustaceans Artemia salina) and low biodegradability (BOD/COD=0.53), which, if eventually released into receiving bodies, can cause irreversible and harmful effects to the aquatic microbiota. The treatment processes studied in this work involved catalytic ozonation mediated by ferrous catalytic material based on steel scale and biological process with Pleurotus Florida fungi, evaluated in an individual way and sequentially integrated as follows: Catalytic ozonation>>biological process and vice-versa. The best results were obtained by applying the sequence "catalytic ozonation>>biological process", which resulted in reductions of 96.2% in soluble lignin concentrations, 93.3% in color units and more than 99% reduction in total phenols, in addition to a low mortality rate of  A. salina (≈10%). In the integrated process, the application of catalytic ozonation before the biological process presents greater advantages because of the pre-decomposition process of recalcitrant compounds by the chemical action of catalytic ozonation, which can convert these compounds into biodegradable, facilitating the action of the biological process for the remediation of the effluent.

Keywords: fungi, ozonation, phenols, wood lamination.

Published: August 2022

Access to drinking water is one of the most important factors for health. The lack of access to safe drinking water results in a high prevalence of infections, such as bacterial gastroenteritis and outbreaks of diarrhea. This study evaluated the quality of the public water supply in 42 municipalities located in the eastern region of the State of São Paulo, Brazil, from 2016 to 2020. Physical, chemical, and microbiological parameters were investigated. Sample collection, preservation and analyses were carried out in accordance with national and international standards. The results demonstrated non-compliance with Brazilian legislation for apparent color (1.1%), turbidity (0.4%), fluoride content (14.2%), total coliforms (4.4%) and Escherichia coli (E. coli) (0.4%). In a brief comparison with other studies in the southeastern region of Brazil, the highest percentage of unsatisfactory samples is due to the fact that fluorine is below the minimum of <0.6 ppm, demonstrating the need for training in the fluoridation process. The need to invest in the training of health surveillance teams to carry out field analyses (chlorine and pH) was also observed. This study can inform future actions, guiding the adoption of preventive and corrective measures and demonstrating the importance of monitoring water-supply quality.

Keywords: drinking water, public health, water quality.
An upper bound on the revised first Betti number and a torus stability result for RCD spaces

We prove an upper bound on the rank of the abelianised revised fundamental group (called “revised first Betti number”) of a compact

\mathsf{RCD^{*}}(K,N)

space, in the same spirit of the celebrated Gromov–Gallot upper bound on the first Betti number for a smooth compact Riemannian manifold with Ricci curvature bounded below. When the synthetic lower Ricci bound is close enough to (negative) zero and the aforementioned upper bound on the revised first Betti number is saturated (i.e. equal to the integer part of

N

\lfloor N \rfloor

), then we establish a torus stability result stating that the space is

\lfloor N \rfloor

-rectifiable as a metric measure space, and a finite cover must be mGH-close to an

N

is an integer, we prove that the space itself is bi-Hölder homeomorphic to a flat torus. This second result extends to the class of non-smooth

Quantifying For-Profit Outcomes in GME: A Multispecialty Analysis of Board Certifying Examination Pass Rates in For-Profit Affiliated Residency Programs
Authors: Lassner Jared W. , Ahn James , Martin Shannon , McQueen Alisa , Kukulski Paul
Published: August 2022

Background

The number of for-profit hospitals has increased in the United States, but their role in and outcomes for graduate medical education (GME) are unclear.

Objectives

To describe for-profit involvement in internal medicine (IM), general surgery (GS), and pediatrics GME by quantifying change in for-profit affiliated residency programs and comparing for-profit and nonprofit affiliated program board certifying examination pass rates.

Methods

We used Accreditation Council for Graduate Medical Education and Medicare data to quantify for-profit prevalence in IM, GS, and pediatrics GME from 2001 to 2021. We used public pass rate data from the American Board of Surgeons (2017-2019; n=242 programs; 6562 examinees), American Board of Internal Medicine (2018-2020; n=465 programs; 23 922 examinees), and American Board of Pediatrics (2018-2020; n=202 programs; 9819 examinees) to model the relationship between profit status and pass rate within each specialty and across specialties combined using linear regression.

Results

The proportion of for-profit affiliated residency programs increased 400.0% in IM, 334.4% in GS, and 23.2% in pediatrics from 2001 to 2021. Bivariate linear regression revealed significantly lower pass rate in for-profit affiliated programs in IM β =-7.73, P<.001), pediatrics (β =-14.6, P<.001), and the 3 specialties combined (β =-5.45, P<.001). Upon multiple regression with addition of program characteristic covariates, this relationship remained significant in pediatrics (β =-10.04, P=.006).

Conclusions

The proportion of for-profit affiliated residency programs has increased in IM, GS, and pediatrics from 2001 to 2021. After controlling for covariates, for-profit affiliated programs were associated with lower board examination pass rates in pediatrics with no association in IM, GS, or the combined measure.
Family Medicine Residencies: How Rural Training Exposure in GME Is Associated With Subsequent Rural Practice
Authors: Russell Deborah J. , Wilkinson Elizabeth , Petterson Stephen , Chen Candice , Bazemore Andrew
Published: August 2022

Background

Rural US populations face a chronic shortage of physicians and an increasing gap in life expectancy compared to urban US populations, creating a need to understand how to increase residency graduates' desire to practice in such areas.

Objective

This study quantifies associations between the amount of rural training during family medicine (FM) residencies and subsequent rural work.

Methods

American Medical Association (AMA) Masterfile, AMA graduate medical education (GME) supplement, American Board of Family Medicine certification, Accreditation Council for Graduate Medical Education (ACGME), and Centers for Medicare and Medicaid Services hospital costs data were merged and analyzed. Multiple logistic regression measured associations between rural training and rural or urban practice in 2018 by all 12 162 clinically active physicians who completed a US FM residency accredited by the ACGME between 2008 and 2012. Analyses adjusted for key potential confounders (age, sex, program size, region, and medical school location and type) and clustering by resident program.

Results

Most (91%, 11 011 of 12 162) residents had no rural training. A minority (14%, 1721 of 12 162) practiced in a rural location in 2018. Residents with no rural training comprised 80% (1373 of 1721) of those in rural practice in 2018. Spending more than half of residency training months in rural areas was associated with substantially increased odds of rural practice (OR 5.3-6.3). Only 4% (424 of 12 162) of residents spent more than half their training in rural locations, and only 5% (26 of 436) of FM training programs had residents training mostly in rural settings or community-based clinics.

Conclusions

There is a linear gradient between increasing levels of rural exposure in FM GME and subsequent rural work.

Authors: Xiao Grace , Sikder Shameema , Woreta Fasika , Boland Michael V.
Published: August 2022

Background

It is essential to log resident-performed procedures to assess training programs and fulfill specialty requirements, but resident case numbers are often underreported. Current systems require inefficient data entry steps, and residents and fellows report that user interfaces and administrative burden contribute to logging inaccuracy.

Objective

To determine the accuracy, feasibility, and acceptability of a single logging approach for resident case logging.

Methods

In 2018, we implemented a case logging system integrated with the institutional electronic health record (EHR) and the Accreditation Council for Graduate Medical Education (ACGME) case log system to record procedures performed by ophthalmology residents. We compared the proportion of resident-performed cataract extractions in the EHR that were reported to ACGME for 3 periods: before the deployment of the new system (6 months), during the transition (6 months), and after the change (2 years). Resident satisfaction with the new system was evaluated using surveys.

Results

An analysis of resident cataract surgeries showed that the percentage of resident cases logged increased from 85% prior to implementation to 91% after implementation. The integrated system became the preferred case logging method, with 100% of all logged cases being entered using the new platform. Surveys showed that the percentage of trainees who were moderately or very satisfied with the case log process increased from 55% before implementation to 100% after implementation.

Conclusions

A resident case log system integrated with an EHR more accurately reflects resident operative volume and increases trainee satisfaction with the logging process.

The prevention, diagnosis, and management of medical emergencies are of utmost importance in the practice of dentistry. Dental students and dental surgeons must be well trained and prepared to manage all possible medical emergencies in their daily professional practices. The team must be competent and confident in handling the initial basic emergency treatment with quality. Proper management of life-threatening medical emergencies may lead to the prevention of possible death and complications. This may also avert the psychological trauma that the healthcare professional may go through and the stigma attached to the hospital or clinic. Besides that, the ethical and legal implications of medical emergencies related to the obligations of the healthcare practitioner cannot be overlooked. The teaching of medical emergencies in our dental schools starts at the pre-clinical undergraduate level. However, the program is not well structured. Despite the consensus on the importance of training in medical emergencies, several international studies show unsatisfactory results by demonstrating low knowledge and confidence of professionals in managing medical emergencies and first aid. As a result of these international research findings, there has been aparadigm shift in teaching undergraduate students in most developed countries. The fundamental change in the approach now is emphasizing on a more competency-based curriculum and more hands-on teaching. Hence the need for a revision and inclusion of medical emergencies in our curricula in Ghana.

Published: August 2022

Farmers in tropical rural areas are confronted with several challenges but outstanding among thesechallenges is soil degradation arising from soil erosion. This study involved identifying the dominant soil andwater conservation practices and assessing the factors affecting their adoption in the Muyembe sub-county,Eastern Uganda. A total of 500 respondents were used to obtain primary data. As the study adopted a crosssectionaldesign, we used questionnaires, interviews, focus group discussions and field observations to collectthe required data. Data were analyzed using descriptive statistics and the non-parametric (Chi-square) test.The results indicated that the dominant soil and water conservation practices adopted in the study area were,contour cropping (77%), mixed cropping (59% and crop rotation (51%). The remaining five practices hadless than a 50% adoption rate. The chi-square test revealed that the age and gender of the farmers had asignificant association with the levels of the adoption of soil and water conservation practices among farmersat P<0.001. We concluded that the adoption of soil and water conservation practices was low, which left themajority of farmers vulnerable to soil erosion effects such as low yields and crop failure. We recommend thatstakeholders who work on soil and water conservation programs use model farmers in the area to educateand demonstrate the importance of soil and water conservation practices to other farmers.
Cloning, over-expression and purification of Escherichia coli murC
encoding UDP-N-acetylmuramate--L-alanine ligase
Authors: Ayush Gowda D A  , Nagamani T S
Published: August 2022

Gene murC encodes Uridine diphosphate N-acetylmuramate–L-alanine ligase, a 53 kDa enzyme
involved in synthesizing the bacterial cell wall. The present study is designed to clone, overexpress
and purify the recombinant murC using Escherichia coli as a model system. murC nucleotide
sequence was obtained from the NCBI Gene database. The murC ORF from the genomic DNA of E.
coli was amplified using primers containing restriction sites and a poly his-tag included in the pET
28b expression vector and was cloned into it. In E. coli BL21(DE3), the recombinant plasmid was
transformed and overexpressed. The overexpressed recombinant His-tagged protein was purified
using an affinity nickel column in a single chromatographic step. Since MurC ligases are a crucial
enzyme involved in the synthesis of the bacterial cell wall and since it is absent in vertebrates
including humans, this enzyme could be a desirable target for the development of antibacterial drugs.
This method could be used for the production of MurC proteins that could help in identifying and
screening small molecule inhibitors against pathogenic bacteria.

Published: August 2022

Football is the most popular sport characterized by high and low intensity movements with repeated physical contact. Anthropometric characteristics, coordination motor skills, and functional movement abilities are part of important determinants of success in a football game. This study investigated the relationship between hand-eye coordination and anthropometric characteristics of professional football players based on their playing position. A correlational research design was utilised for this study. The population for this study comprised of 29 professional football players who are members of a professional football club in Nigeria. The participants comprised of 12 forwards, 6 midfielders, 4 goalkeepers and 7 defenders. The weight, height, waist circumference, and hip circumference measurements were obtained using standardised procedures. The body mass index and waist to hip ratio scores of the participants were calculated. The alternate hand wall toss test was used to determine the hand-eye coordination of the participants. Pearson’s product moment correlation and linear regression were used to analyse the results. The level of significance was set at p < 0.05. A significant negative strong correlation was observed between waist to hip ratio and coordination among midfielders (r = -0.841, p = 0.036). There was no significant correlation between waist to hip ratio and coordination among forwards, defenders, and goalkeepers. In addition, there was no significant correlation between body mass index and coordination as well as waist circumference and coordination among football players in all the playing positions. Waist to hip ratio is an important anthropometric measure that can affect the coordination of midfielders in a football team. This should be considered by the coaches and football regulatory bodies before players are assigned to playing positions in the game of football. Position-specific training programmes should be encouraged to enhance football players' performance.
Are Green Jobs Advocates Their Own Worst Enemies?
Authors:   Management Information Services, Inc. Oakton, Virginia, USA, Bezdek Roger H
Published: August 2022

There is intense controversy in the USA concerning the definition of green jobs. We review the definitions being used, note their shortcomings, and summarize criteria for green jobs being utilized by advocates and politicians – including President Biden. We find that green jobs advocates can be their own worst enemies. They have significantly tightened the criteria for characterizing green jobs and have greatly reduced the number of jobs that can thus be defined as “green.” We find the overwhelming majority of green jobs do not adhere to these criteria and that that very strict criteria greatly reduce green jobs estimates. We conclude that utilization of these criteria will very seriously underestimate the size, importance, and rates of growth of the USA green economy and green jobs. This will hinder efforts to address pressing environmental and energy issues, to increase green jobs, and to implement the Democrats’ Green New Deal.

The hazard index values as Radium Equivalent Activity (Raeq), Representative Level Index (Iγ ), Absorbed Dose Rate (D), and Annual Effective Dose Rate (Deff) were 68.51 ± 41.43 Bq.kg-1, 0.49 ± 0.30; 124.14 ± 66.16 nGy.h-1 and 0.93 ± 0.50 mSv.y-1 respectively. These values are below the permissible limits and in the safe zone category
Design of Typical Energy Efficient and Zero Energy building for Kabul City
Authors:   Energy Engineer, Energy Engineering faculty of Kabul University, Kabul, Afghanistan, Ahmadi Ahmad Masih
Published: August 2022

Recently, the consumption of energy in residential buildings has been increasing. On one hand, urbanization increased energy consumption in residential buildings. On the other hand, construction of nonstandard buildings especially residential buildings, caused excessive energy waste. Implementation of energy efficiency and zero-energy building strategies is one of the best solutions to decrease energy waste and energy intensity in a residential building in Kabul City. This research is conducted to design typical energy-efficient and zero energy building strategies for Kabul City. The majority of people use unrefined fossil fuels for heating. As we know, fossil fuels cause environmental pollution. To burn these fuels, most greenhouse gases GHGs emissions are released in the atmosphere, and these GHGs are very harmful to health and cause different types of illnesses. This study is performed in two stages. First, the construction cost of a customarily built building is calculated. Then, the heat loss and heat gain of this inefficient building are also calculated. The same procedure is repeated for a more efficient and insulated building. After comparing, it is revealed that an insulated building saves 65% of the energy and emits 60% less CO2 compared to the inefficient building. To make this building a zero-energy building, we tried using photovoltaic technology. All-electric loads for this building are calculated, and the components of the photovoltaic system are designed accordingly. Finally, the implementation of energy-efficient and zero-energy building has lots of benefits of cost-saving, being environmentfriendly, reduced illness, and individual sustainability for each building

WHO Director-General Tedros Adan Ghebreyesus announced on May 21, 2021, at the 74th World Health Assembly, that at least 115,000 health workers had died during the novel coronavirus pandemic. Analysis of literary sources showed that significant losses are borne by the doctors of the “Red Zones” of hospitals: doctors, nurses, as well as doctors, paramedics, ambulance drivers. The most likely cause of such losses is considered by health experts from different countries: an increased load on staff, which leads to early “Professional burnout” and “Emotional fatigue”, a higher probability of infection with the virus. This does not take into account other, probable causes, for example, distant interactions or the “Kaznacheev effect”.

The Ecology of Tree Roots and the Practical Significance Thereof
Authors: Perry Thomas O.
Published: August 2022

Tree root growth is opportunistic and occurs wherever the environment is favorable. A balance exists between the root system and the remainder of the plant, so that if part of the root system dies, part of the crown will also die. Both parts are connected by a well-developed conduction system. Approximately 99 percent of the roots occur within the surface meter of soil and extend outward over an area one to two or more times the height of the tree. Large woody roots form the framework and are typical in pattern for each species. The fine feeder roots occur in the leaf and litter layer, if present, and the surface mineral soil. Keen root competition occurs at the surface if a turf exists under the tree. Also, herbicides, etc. used on lawns may have detrimental effects on the trees through these fine absorbing roots. In the urban environment roots may follow cracks and crevices in pavements, pipelines, sewers and cables. At the same time the installation of these utilities may cut across established tree root systems with unfortunate consequences.
Biology and Control of the Mealy-Oak Gall
Authors: Morgan David L. , Frankie Gordon W.
Published: August 2022

Galls are commonly found on urban trees. Induced by oviposition of insects and other arthropods, galls develop from woody tree tissues, forming shelters for developing larvae. Few galls are physiologically harmful to the tree. Some, like the mealy-oak galls on live oak, are not only harmless but may harbor beneficial arthropods long after the gall-maker has departed. Because chemicals will not penetrate the gall, and the activities of the gall-formers are extended over time, the use of chemical pesticides to control gall-making is unreliable. The preferred use of resistant trees is discussed.

Growth of rooted cuttings of Hicks yew(Taxus × mediacv. ‘Hicksii’) in selected media at different fertility levels and light intensity was evaluated. Applications of 20-20-20 at 380 ppm N with every watering resulted in a reduced growth compared to 120 to 192 ppm N. Shoot length growth was superior at 50% shading when compared to no shading, regardless of the media and fertility levels.

Published: August 2022

Objective: Peripartum hysterectomy is a life-saving procedure performed during and after vaginal delivery or cesarean section. The incidence of placental invasion anomaly is increasing in parallel with the increase in the number of births by cesarean section. It was aimed to evaluate the frequency, risk factors and outcomes of peripartum hysterectomy performed in a tertiary hospital. Materials and methods: Research data were obtained by a retrospective review of patient files. Patients who underwent peripartum hysterectomy because of postpartum hemorrhage in the Gynecology and Obstetrics Clinic of Trabzon Kanuni Training and Research Hospital, University of Health Sciences, Turkey, were included in the present study. The patients were divided into two groups as those who underwent emergency peripartum hysterectomy (EPH) and those who did not. Demographic variables, fetal and maternal mortality, EPH indications, additional surgeries performed during EPH, and intra- or postoperative complications were collected. Pearson chi-square test was used for statistical analysis. Results: There were 22,464 deliveries, of which 13,514 were delivered vaginally and 8,950 by cesarean section. Peripartum hysterectomy was performed on 42 patients (vaginal 16, cesarean section 26). The most common EPH indications in both groups were placenta accreta spectrum (42.9/3.2%), followed by uterine atony (38.1/2.5%). The most common risk factor for EPH was found to be a history of previous cesarean sections. Conclusion: Placental invasion anomalies that cause severe postpartum hemorrhage are due to increased cesarean rates. Currently, the most common indication of EPH is placental invasion anomalies. Key words: peripartum hysterectomy – placental invasion anomaly – postpartum hemorrhage
Hydronephrosis as a symptom of clinically silent ureteral endometriosis

Published: August 2022

Objective: We present two case reports of asymptomatic ureteral endometriosis leading to hydronephrosis. We demonstrate the significance of routine ultrasound scanning of the upper urinary tract in patients with diagnosed deep infiltrating endometriosis. Case reports: The first case report describes a symptomatic patient after a surgery for deep endometriosis. After the surgery, she was completely without symptoms, but during regular check-ups she developed progressive hydronephrosis on the right side and it did not respond to conservative treatment. Surgery deliberation of the ureter was indicated. The second case report describes a patient with already developed severe hydronephrosis on the left side. The functional kidney examination proved complete renal loss of the left kidney. Because of recurrent pyelonephritis in the nonfunctional kidney, nephrectomy was indicated. Conclusion: Ureteral endometriosis presents a rare, but insidious form of endometriosis, which is very often asymptomatic and diagnosed at a later stage. It can cause a complete silent loss of renal function. Routine ultrasound scanning examination of the upper urinary tract in all patients with diagnosed endometriosis could prevent this severe complication. Key words: ureteral endometriosis – hydronephrosis – routine US scanning
Balloon vaginoplasty as a minimally invasive method in the management of vaginal aplasia
Authors:   Department of Gynecology and Obstetrics, Šumperk Hospital a.s., Czech Republic, Maršálková Kristýna
Published: August 2022

Objective: The aim of this article is to describe the management of vaginal aplasia and to introduce minimally invasive surgical procedures for neovagina formation. Methodology: Literature review obtained from studies and papers dealing with the management of congenital vaginal aplasia. Conclusion: Vaginal aplasia is a rare congenital anomaly, often in coincidence with congenital defects of the uropoietic system. Management nowadays favors non-surgical or minimally invasive surgical methods for neovagina formation. Saman et al introduced a new method of neovagina formation, namely balloon vaginoplasty. The advantage of the surgical procedure is traction using a soft Foley balloon, determining both the length and width of the neovagina. The method uses the expansion of the natural vaginal mucosa without the need for dissection of the vesicorectal space. The soft Foley balloon does not cause erosion of the vaginal mucosa. Key words: vaginal aplasia – Mayer-Rokitanský-Küster-Hauser syndrome – minimally invasive surgical method of neovagina formation – laparoscopically assisted balloon vaginoplasty – retropubic balloon vaginoplasty

Universitas Dhyana Pura adalah perguruan tinggi swasta yang ada di bawah naungan Yayasan Dhyana Pura yang ada di Kabupaten Badung Bali. Setiap program studi yang bernaung di bawah sebuah Perguruan Tinggi diwajibkan menjaga jaminan mutunya melalui proses Akreditasi. Adapun Instrumen akreditasi Program Studi yang Data, informasi dan penjelasan setiap kriteria dan parameter yang diminta dirumuskan dan disajikan oleh program studi dalam instrumen yang berbentuk panduan pengisian dokumen kinerja program studi (Buku IIIA) dan panduan penyusunan Laporan Evaluasi Diri (LED) atau Self Evaluation Report (SER) (Buku IIIB). Masing- masing program studi yang ada di Universitas Dhyana Pura pun tidak luput dari upaya memperoleh status akreditasi baik yang dilakukan pada periode tertentu.  Masalah yang sering kali muncul adalah data dan informasi yang terkait Instrumen Akreditasi Program Studi belum tertata dengan rapi.  Jika tidak ada sebuah data center (sumber data) yang dapat dimanajemen secara periodik, maka pencatatan akan terjadi berulang-ulang, padahal informasi sebelumnya sangat berguna pada penyusunan borang akreditasi selanjutnya. Oleh sebab itu, diperlukan suatu sistem informasi yang dapat memanajemen Keperluan – keperluan Dokumen terkait Akreditasi Program Studi. Sistem informasi ini akan membantu Unit Pengelola Program Studi dan Program Studi dalam mengelola dokumen kinerja dan laporan evaluasi diri program studi sesuai dalam Pedoman Pengisian Dokumen Kinerja dan Laporan Evaluasi Diri Akreditasi Program Studi. Sistem informasi tersebut akan mempercepat proses dalam akreditasi sehingga hasilnya akan lebih teliti dan menghemat anggaran, waktu dan biaya
