AbstractTo reveal optimal antibiotic prophylactic regimen for postoperative endophthalmitis (POE), we conducted systematic review and network meta-analysis. A total of 51 eligible original articles, including two randomized controlled trials, were identified. In total, 4502 POE cases occurred in 6,809,732 eyes (0.066%). Intracameral injection of vancomycin had the best preventive effect (odds ratio [OR] 0.03, 99.6% confidence interval [CI] 0.00–0.53, corrected P-value = 0.006, P-score = 0.945) followed by intracameral injection of cefazoline (OR 0.09, 99.6% CI 0.02–0.42, corrected P-value < 0.001, P-score = 0.821), cefuroxime (OR 0.18, 99.6% CI 0.09–0.35, corrected P-value < 0.001, P-score = 0.660), and moxifloxacin (OR 0.36, 99.6% CI 0.16–0.79, corrected P-value = 0.003, P-score = 0.455). While one randomized controlled trial supported each of intracameral cefuroxime and moxifloxacin, no randomized controlled trial evaluated vancomycin and cefazoline. Sensitivity analysis focusing on the administration route revealed that only intracameral injection (OR 0.19, 99.4% CI 0.12–0.30, corrected P-value < 0.001, P-score = 0.726) significantly decreased the risk of postoperative endophthalmitis. In conclusion, intracameral injection of either vancomycin, cefazoline, cefuroxime, or moxifloxacin prevented POE.

AbstractThis study aimed to assess the association between interpregnancy interval (IPI)—the time from childbirth to conception of the next pregnancy—and maternal and neonatal morbidity. The World Health Organization (WHO) currently recommends an IPI of at least 24 months after a live birth to reduce adverse birth outcomes. However, assessing the relationship between IPI and perinatal outcome is complicated by confounding factors. We conducted a nationwide population-based cohort study using Swedish registry data, allowing for adjustment of maternal characteristics and health at first birth. The study population consisted of all women with a singleton, live, and vaginal first birth with a second singleton birth within five years during 1997–2017, covering 327,912 women and 655,824 neonates. IPI was grouped into six-month intervals with 24–29 months as the reference. The association between IPI and morbidity was examined using multivariate logistic regression. For women having a vaginal delivery at their first birth, intervals < 24–29 months were associated with decreased maternal morbidity and unaffected neonatal morbidity. Intervals > 24–29 months were associated with increased maternal and neonatal morbidity. Our findings question the relevance of WHO’s recommendation of an IPI of at least 24 months in a high-income country.

Published: October 2022

AbstractA suitable mixture of renewable resources including wind, tidal and photovoltaic units can be used in the microgrids installed in coastal areas or islands. However, the variation in the renewable resources such as wind speed, tidal current speed and solar radiation is significant that affects the reliability performance of these microgrids. Thus, to accurately evaluate the reliability of the microgrids, the failure rate of composed components affected by the variation in the renewable resources must be considered. To study the impact of variation in the temperature and renewable resources on the failure rate of components, different equations including Arrhenius law, temperature modification factor, fatigue strength, bending and contact stress, limit state function of turbine, thermal loss of semiconductor devices, the temperature rise of transformer and cable, the temperature coefficient of voltage and power of photovoltaic panels are developed. According to the developed equations, the components failure rate, and consequently the failure rate of the microgrid considering the variation in the temperature and renewable resources are determined. Then, by simulation, the impact of different energy sources on the failure rate of the whole system is evaluated and the reliability in a microgrid consisting of offshore renewable energy sources will be studied.
Design and fabrication of an interleaved high step‐up DC–DC converter with soft‐switching capability to implement in renewable energy systems
Authors: Jouzdani Marzieh Mohammadi , Shaneh Mahdi , Nouri Tohid 
Published: October 2022

AbstractThis paper presents a soft‐switching non‐isolated interleaved high step‐up topology to implement in renewable energy systems. By using low number of power electronic devices and incorporation with the coupled inductors (CIs) and built‐in transformer (BIT), simultaneously, mixed with a voltage multiplier cell (VMC), an ultra‐large gain can be obtained. In addition, the interlevead structure in the input side causes to diminish the input current ripple. Moreover, the automatic current sharing is another characteristic of the proposed converter. The voltage stresses across power semiconductors are decreased by increasing the turns ratio of the implemented CIs and BIT and also reverse recovery losses are attenuated which improves the efficiency. Furthermore, zero‐current‐switching (ZCS) condition for diodes is achieved at turn off instant, due to the leakage inductances of the magnetic means. Also, power MOSFETs are switched with zero‐voltage‐switching (ZVS) performance by adding active clamp. A 600‐W experimental prototype with 24‐V input to 400‐V output voltage at a switching frequency of 100 kHz is built and tested to examine the merits of the proposed topology

Abstract
Background Quadriceps muscle plays a relevant role in soccer as its
function is determinant for sprinting, jumping and striking the ball. Although
ultrasound demonstrated to be useful in risk of injury prevention and monitoring
post-injury rehabilitation, no studies analyzed the ultrasound muscle histology
with sports performance tests. We aimed to analyze the correlation between
ultrasound findings related to rectus femoris morphology and composition with
sports performance indicators and to analyze sociodemographic, sports
performance and ultrasound differences according to playing position.
Methods An observational study was conducted at the CFF OLYMPIA soccer
club (Madrid, Spain). Twenty-two semi-professional female soccer players were
enrolled in this study. Sociodemographic data, bilateral ultrasound measurements
of the rectus femoris muscle and sports performance tests (Counter Movement Jump
-CMJ-, The Sprint Repeat Ability -SRA-, and one Repetition Maximum -1RM-) were
collected.
Results No correlations between ultrasound imaging and sports performance
indicators were found. Significant correlations between cross-sectional area and
perimeter with age (p<0.05) and fatty infiltration with body mass index
and tight perimeter (p<0.05) were seen. No muscle ultrasound morphology
or quality differences were found between the playing positions
(p>0.05). Finally, most of the functional tests showed no
between-position differences (except SRA between goalkeepers and attackers).
Conclusion Although muscle morphology and quality are associated with
demographic features, US should not be used as a predictor of sports performance
in female football players since no association between US and sports
performance were observed. Similar US and functional test scores were obtained
among the different playing positions.

Published: October 2022

Abstract
Background Hyposmia is one of the most common, as well as the first nonmotor condition in Parkinson disease (PD). The sniffin sticks test (SST) evaluates three different aspects of olfactory function: threshold (T), discrimination (D), and identification (I). The sum of the scores of these three subtests produce a global score of olfaction, the Threshold-Discrimination-Identification (TDI) score.
Objective The aim of this study was to investigate if the TDI score or one of its subtests is better to discriminate PD patients from controls.
Methods We recruited 27 PD patients and 17 healthy age-matched controls (HC) who were evaluated through a clinical interview, the Montreal Cognitive Assessment and Movement Disorders Society – Unified Parkinson Disease Rating Scale. The olfaction was assessed using the complete SST.
Results The performance of PD patients on the olfactory test was significantly worse when compared with the HC (T: 3.0 vs. 6.5, p < 0.001; D: 8.1 vs. 11.2, p < 0.001; I: 7.3 vs. 11.7, p < 0.001; TDI: 18.8 vs. 29.9, p < 0.001). The prevalence of olfaction impairment in our study (PD: 100%, and HC: 56%) was greater than that found in the literature. Cognition influenced the performance on TDI. The olfactory subtests were impaired proportionally between patients and controls. Furthermore, D and I were correlated, but only in PD patients. The TDI showed a tendency to better discriminate PD patients from HC, when compared with its subtests.
Conclusions Although the complete olfactory evaluation is time consuming, it seems to be a superior tool to identify olfaction impairment in PD patients, when compared with the isolated subtests.
Lateral Horizontal Head Position Approach for the Lateral and Anterior Third Ventricles: A Subependymoma Clinical Case and Literature Review
Authors: Doğu Hüseyin , Akdemir Hidayet , Çetin Sırma 
Published: October 2022

AbstractSubependymomas are benign, slow-growing, noninvasive solitary lesions of World Health Organization Grade I cerebral ependymal origin that are rare compared with other types of ependymomas. Anterior third ventricle subependymomas are usually detected during autopsies in cases of sudden death due to acute or intermittent obstruction of the cerebrospinal fluid passage. Different surgical approaches are used for these cerebral lateral and third ventricular lesions. Serious complications can occur, either because of brain edema and acute intracranial pressure due to the lesion itself or the chosen head position and continuous use of brain retractors during the surgical procedure.In this case report, we trust that the surgical principles we applied with the aid of two cotton pads, gravity assist, and lateral horizontal head position, and without continuous use of brain retractors in the third ventricular lesion in the transcallosal interhemispheric approach are safe and secure in preventing perioperative brain edema or early postoperative neurological complications.
Designing an evaluation system to assess professional ability training in police colleges
Authors: Wang Qilei 
Published: October 2022

AbstractDrawing on the main characteristics of police professional education, this paper proposes an evaluation index system consisting of four subsystems and their index sets, in which society, police units, colleges, and students themselves jointly participate. The objective of this paper is to extract both subjective and objective evaluation information to develop an effective evaluation index system for professional education in police colleges. This paper uses a method based on improved information entropy to determine the weight of each index in the evaluation system, employs this weight calculation function to determine the subjective and objective weights of each index comprehensively, evaluates the professional education of police colleges using the improved fuzzy matter-element model, and verifies the training situation faced by graduates of the police university. The results show that combined with the evaluation system thus constructed, the entropy weight and fuzzy element model exhibit strong integrity and systematicity with respect to the evaluation of professional education in police colleges and that the evaluations produced by this approach are consistent with expert analysis. The evaluation thus becomes more comprehensive and objective and receives more social recognition.

Context The number of women who achieve pregnancy through assisted reproductive technology (ART), including in vitro fertilisation and embryo transfer (IVF-ET), is increasing worldwide. Placenta-mediated diseases associated with ART, such as gestational hypertension, preeclampsia, disorders of placental implantation, and placental abruption, are also increasing. Aims To determine the association between placental pathologies and IVF-ET in women with preterm births. Methods This retrospective cohort study examined archived placenta specimens of women who achieved pregnancy through either spontaneous conception or IVF-ET. In total, 1677 women with singleton pregnancies who gave birth consecutively between 20 and 37 weeks of gestation at Seoul National University Bundang Hospital and underwent placental pathologic evaluation between April 2013 and October 2018 were included. Data from all pathologic reports were reviewed. Key results The IVF-ET group had a higher median maternal age and rate of nulliparity than the natural conception group. The incidence rate of obstetric complications, except preterm premature rupture of membranes and placenta previa, was similar in both groups. The IVF-ET group had a higher incidence rate of placental infarction than the natural conception group (26.4% vs 16.4%, P = 0.012). Multivariate logistic regression analysis indicated that IVF, hypertensive disorders, and fetal growth restriction were significantly associated with placental infarction. Conclusions IVF-ET was independently associated with the risk of placental infarction in women with preterm births. Implications The use of IVF-ET may cause abnormal placental formation with an increased risk of anatomical and vascular pathology, which are observed in preterm deliveries and may contribute to pregnancy complications.

Published: October 2022

Abstract
This study aims to determine physiographic characteristics based on the slope and land use which affect water control in Embung Hendrosari area, Gresik. The data used in this study are DEM data, Landsat 8 image data, and river data. The slope data processing is carried out through slope classification analysis. The Landsat 8 data processing is used for land use classification analysis. The slope classification maps and land use classification maps are used to classify flow coefficients. There are five land classifications obtained in land cover classification map including agriculture, settlements, industrial areas, plantations, and waters. There are 5 classifications obtained on the slope classification map, including flat, sloping, slightly steep, steep and very steep. The flow coefficient analysis is performed from the combination of land use data and slope data. The flow coefficient is influenced by the characteristics of the land cover and the slope of the slope. The average flow coefficient of Embung Hendrosari area is 0.31, which classified as medium flow coefficient. This indicates that 31% of the water is run off on the ground surface and 69% of the water is absorbed below the soil surface. There are changes in land function in Embung Hendrosari area, for example, agriculture area which changed into settlement and/or industry, which will significantly affect the value of the flow coefficient. The change in land use causes more water to run off the surface. This runoff water management requires a water reservoir that can be directed toward reservoir. The results of this study show such an initial step in hydrological engineering by its development, improvement, utilization, and control of water flow by utilizing the function of Hendrosari Gresik reservoir.

Published: October 2022

Abstract
The availability of land cover in the form of forest is very important in the watershed system (DAS). The decrease in forest cover and the carbon content stored in a watershed also shows a decline in the quality of the watershed. The research aims to examine changes in land cover that occurred during the last twenty years in the Pengabuan Watershed. Changes in land cover were obtained by classifying Landsat imagery from 1996 to 2017. Classification was carried out using the supervised classification method and visual interpretation and then followed by change detection analysis. The result showed that from 1996 to 2017, secondary dryland forest cover and bare land in the Pengabuan watershed has been declining, the rate of secondary dryland forest decreased by 53.38% (11,186.47 ha / year), the rate of decline in bare land by 1, 26% (264.29 ha / year). Land cover with an increasing area such as settlements at 2.29% (479.24 ha / year), plantation forests at 17.31% (3,626.75 ha / year), dry land agriculture at 1.63% (341, 41 ha / year), plantations at 33.12% (6,940.13 ha / year) and water bodies at 0.30% (62.94 ha / year). Changes in land cover are caused by increased land requirements for various uses and implementation of government policies. Forest cover in Pengabuan Watershed in 2017 only covers 14.1% of the total area of the Pengabuan Watershed (419,114.49 ha). This shows that the minimum coverage of existing forest in this watershed area has not reached 30%. Changes in land use patterns are one factor in causing the decrease of carrying capacity of watersheds. Conversion of forest cover, especially forest areas into plantations, agriculture, bare land and others, has led DAS area vulnerable to the occurrence of floods, erosion, the threat of drought in the dry season, decreased water quality, land productivity and the threat of siltation of the estuary due to sedimentation.

Published: October 2022

Abstract
During last decades, various mints of different countries manufactured a large amount of holed metal coin currency. As main characteristic, these holed metal coins present a central round perforation, which changes some of the initial manufacturing condition, as different coin blank or striking dies model. During the manufacturing process, these coins may encounter some error types which depend by the die dimension, the model flat area size or contour shape. Many pieces wearing these errors were minted and released; in present days these are searched and valuated by collectors. The paper work presents different aspects about the dies damages appeared at the metal holed coin striking process. In the paper beginning part, some particular introductive considerations about the holed metal coins manufactured with cracked dies error are presented; there are presented some examples. Then the simplified blank and the obverse and reverse dies 3D model are introduced, followed by the assembled model which consist in the obverse and reverse negative dies having the coin blank inside them. For these models, the finite element analysis is computed and achieved for different initial inputs. In the last part of the paper work, the analysis results and main conclusions on these are presented.

Abstract
The article considers the influence of the content of HB-4 amorphous alloy on the tribological properties of aromatic polyamide phenylone C-2. It was found that the introduction of a dispersed filler in the amount of 10-20 mass.% leads to a positive effect: reduction of abrasion index and roughness during friction on rigid abrasive particles of the original polymer 4,7 and 1,4 times, respectively, reaching minimum values at 20 mass.% of the filler. The improvement in properties occurs due to the fact that the particles of the hard alloy (607–809 HV) strengthen the polymer matrix; as a result, the surface of metal polymers undergoes less deformation. It was found that the effective content of filler for aromatic polyamide is 20 mass.%.
