Authors: Ho Nhat Quang , Vuong Anh Dinh Bao , Quang Le Thanh 
Published: February 2022

Spontaneous unscarred uterine rupture (SUUR) is a catastrophic obstetric complication. We presented a case of the woman at 34 weeks of gestation without apparent causes of SUUR.: A 28-year-old primigravid woman in her third trimester came to the hospital because of abdominal pain. She had a history of endoscopic surgery for adhesiolysis of bilateral fallopian tubes and untreated thyroid disease. Out of the typical vital signs, preeclampsia was diagnosed. After considering the results of ultrasound images with massive free fluid in the abdomen, the emergency exploratory laparotomy was conducted. We delivered an alive baby and repaired the uterine rupture site. The patient was discharged on the 5 postoperative day in a stable condition.: The endoscopic surgery for adhesion separation of the fallopian tube could be a risk factor for SUUR. Timely diagnosis and management plays a crucial role in the prognosis of women suspected of SUUR.

Published: February 2022

Microscopic Enteritis (ME) is characterized by increase in intraepithelial lymphocytes (IEL) in intestinal mucosa. It represents a common feature of broad group of diseases including gluten mediated and non gluten related diseases. Duodenal biopsies play an important role in diagnosing these group of disorders. To compare IEL counts in Hematoxylin and eosin (H & E) stain and CD3 immunohistochemical (IHC) stain in duodenal biopsies of suspected malabsorption cases and compare them with clinical, immunological and biochemical parameters. This was a prospective study of two years. 164 patients were studied. IEL counted at villous tip and base in H&E sections and IHC were compared in duodenal biopsy. Data of clinical history, other parameters were collected and correlated whenever available. To compare any two variables, Chi - square test and independent T test was used. Statistical significance was defined as p &#60; 0.05. Out of 164 cases,105 cases had increased IEL. The age range was 4 to 94 years with mean age of 43.29 ± 17.96 years. Males (56, 53.3%) were affected more than females (49, 46.6%). The clinical and histological parameters showing statistical significance with raised IEL were pallor, dyspepsia, loss of appetite, crypt architecture, blunting, ulcer, villous crypt ratio, exudates, reactive atypia and edema with P&#60; 0.05. IEL at villous tip in CD3 had highest sensitivity (100%) and specificity (92.20%) in our study.ME should be investigated and diagnosed in correlation with a detail clinical history, complete haematological, biochemical and serological findings.

: In developing countries like India, the burden of cervical cancer is still high. According to the World Cancer statistics, &#62;80% of all the cervical cancer cases are found in developing and low-resource countries, because of a lack of awareness. Apart from diagnosing cervical cancers pap test also aids in the diagnosis of inflammatory conditions. : This is a retrospective study carried out at A.C.S Medical college and hospital, Chennai during January 2018- to June 2019. Total of 892 pap smears are included in the study. Both endocervix and ectocervix were sampled. Immediately slides were fixed in 95% ethyl alcohol and subsequently stained by PAP and Hand E stains. Stained slides are mounted with DPX and reported by Pathologist according to Bethesda system. The data was collected and analysed statistically.: A total of 892 pap smears are included in the study. Out of which, 701 smears were found to have pathology accounting for 78.5%. 396 smears were found to be inflammatory accounting for 56.4%.ASCUS, AGUS and HSIL were accounting for 11.9%, 9.4% and 2.4% respectively.: We can conclude Pap test is a simple, cost effective tool in the diagnosis of Inflammatory, Premalignant and Malignant lesions of cervix. Awareness and screening programmes have to be done effectively which helps in detection of premalignant lesions and reduce the incidence of cervical cancer.

Published: February 2022

Objective: This study was conducted to evaluate the association of echocardiographic parameters used in left ventricular (LV) diastology with the early results of non-ST elevation acute coronary syndrome (NSTE-ACS) workup in the hospital.
Methods: This cross-sectional study was performed on patients presenting with acute chest pain and a diagnosis of NSTE-ACS including only patients with unstable angina (UA) and non-ST elevation myocardial infarction (NSTEMI). All patients underwent transthoracic echocardiography in the emergency room (ER) within 12 hours of the last episode of chest pain. An invasive approach was not uniformly pursued in all of the patients so analysis was performed in two different settings. First, analysis was performed in the patients that underwent coronary angiography (CAG) and echocardiographic data were compared between those with normal and abnormal CAG results. Finally, echocardiographic data of the patients with normal diagnostic results (i.e., normal exercise tolerance test (ETT), myocardial perfusion imaging (MPI) or coronary angiography (CAG) results) were compared with the data of the patients with abnormal test results.
Results: Eighty patients with a mean age of 54.43 ± 12.38 years were included in the study, of whom 57 (71.2%) were male. Fifty-three patients underwent CAG. In these 53 patients, there was significant difference in mitral annular velocity in early diastole (e’), ratio of mitral inflow velocity to e’ (E/e’), left ventricular end-diastolic diameter (LVEDD) and left ventricular end-diastolic pressure (LVEDP) between patients with coronary artery involvement and those with normal coronary artery (P<0.05). The area under the receiver operating characteristic (ROC) curve to predict CAG results for e’, E/ e’, LVEDD and LVEDP was more than 0.65. The sensitivity and specificity of the LV diastolic dysfunction for predicting coronary involvement was 94.4% and 35.29%, respectively. Comparison of echocardiographic data between patients with normal test results (non-invasive and invasive) and those with abnormal diagnostic tests showed a significant difference in e’, E/e’, acceleration time of E, LV end-diastolic diameter index, size of interventricular septum and left atrial volume.
Conclusion: The results suggest that diastolic dysfunction data can be used as an adjunctive method to evaluate ACS patients in the ER.

Published: February 2022

Objective: The present study aimed at evaluating the role of training in improving emotional intelligence (EI) skills and assessing its indirect effect on reducing job stress in emergency medicine residents (EMRs).
Methods: In the present study, 20 EMRs were trained for EI skills while 22 EMRs received no training. Then, all participants’ EI level and job stress were assessed and compared before and after the intervention using the Bar-On Emotional Quotient Inventory(EQ-I) and the Osipow job stress questionnaire, respectively.
Results: The results of the present study revealed that the EI level in the training group with a mean score of 338.27±27.57 was significantly higher than the control group with a mean score of 320.50±28.50 after training intervention (P=0.043). In addition, job stress in the training group with a mean score of 170.82±16.11 was significantly lower than the control group with a mean score of 183.30±22.21 (P=0.045). Moreover, in the training group, the relationship between EI and job stress was inverse and significant (r= -0.746, P<0.001), but in the control group it was non-significant (r=0.017, P=0.938).
Conclusion: According to the results of the present study, training for EI skills can play a significant role in improving EI and reducing stress in EMRs.

Published: February 2022

The research purpose was to investigate factors that affect Sales of International Solar Mini-Grids in Tanzania Mainland. The motivation for the study was because there was evidence of a decline in sales of International Solar Mini-Grids in Mwanza, Dar es Salaam, and Arusha regions. The study used a sample size of 70 respondents, a cross-section survey, primary data, and secondary data. The study used the mixed methods research design. Multiple linear regression was employed in quantitative data analysis with the aid of SPSS. Thematic analysis was conducted to derive themes from the qualitative data and information obtained was utilized to supplement the quantitative data. The study revealed that government policies, more specifically energy policy, significantly affect sales of International Solar Mini-Grids in Tanzania Mainland. In addition, the regulatory framework, particularly tariff, significantly affects sales of International Solar Mini-Grids. Also, customers’ purchasing tendencies were significantly affecting the sales of International Solar Mini-Grids. The findings imply that ignoring the factors affecting sales of International Solar Mini-Grids in Tanzania Mainland might worsen the power sector and solar Mini-Grids sustainability. This work recommends that to foster the sales of International Solar Mini-Grids, the government should have a suitable energy policy and regulatory framework geared to enhance the marketability of electricity and enhance customer purchase. The study contributes to knowledge by offering empirical evidence on renewable energy that will be of paramount importance to other renewable energy stakeholders.

Published: February 2022

The determination of retailers to deal with the challenges of managing perishable products’ category continues as they persist to provide quality service and fresh products to their customers. These challenges often afflict retailers and consumers alike, which innately impact category management and good consumer behavior. This article reports on a study that investigates the influence of category management on consumers’ purchase behavior of perishable products. The objectives of this article are to determine the influence of category management on purchase behavior, to explore the current retail category management practices for perishable products, and to investigate the relationship between pricing and shelf life of perishable products and how this relationship influences consumers’ purchase behavior. To achieve these objectives, in-depth semi-structured qualitative interviews that were explorative by nature were conducted, with ten (10) staff members of a selected store in Durban, South Africa, who were responsible for the perishable products category. The findings reveal that category management does influence the purchase behavior of perishable products; however, problems were identified concerning assortment planning, shelving, promotions, pricing, and shelf life. The results were limited to this Durban store. Recommendations were made to the retailers to solve those problems to effectively satisfy consumers.
Factors Affecting Shrinkage Crack Development in Clay Soils: An Experimental Study
Authors: Lokre Chinmay V. , Shakoor Abdul , Wells Neil A. 
Published: February 2022

ABSTRACT
Clay soils are widely used in constructing embankment dams, levees, highway embankments, sanitary landfills, and hydraulic barriers where they are compacted at maximum dry density and optimum water content. These structures are exposed to many cycles of wetting and drying during their service life, resulting in volume changes and developing shrinkage cracks. This study investigated the effect of density, water content, drying temperature, layer thickness, plasticity index, and multiple wetting and drying cycles on shrinkage crack parameters (length, aperture, and area). Five samples each of low-plasticity clay, medium-plasticity clay, and high-plasticity clay at water contents on both sides of optimum water content were compacted and then oven dried at temperatures of 10°C, 20°C, 30°C, 40°C, and 50°C. Upon complete drying, crack length, aperture, and area were digitally measured. Additionally, we saturated uncompacted clay layers of varying thicknesses (5, 7, 10, 20, and 30 mm) of the three clay types and oven dried them at the listed temperatures to investigate the effect of layer thickness on shrinkage crack parameters. The length, aperture, and area of the cracks were correlated with the influencing factors. Among the compacted samples, only high-plasticity clay samples developed shrinkage cracks, exhibiting an increase in crack length, aperture, and area with an increase in dry density and water content. For the uncompacted samples, crack length and crack area decreased with increasing layer thickness, whereas crack aperture increased.
Eigenmode Decomposition of the Diffusion Equation: Applications to Pressure-Rate Deconvolution and Reservoir Pore Volume Estimation
Authors: Kubota Leonardo , Piccinini Rodrigo 
Published: February 2022

SummaryThis paper proposes the application of the eigenmode decomposition to the problem of pressure-rate deconvolution. The method enabled us to write the solution of the pressure-rate deconvolution as an infinite series of eigenmodes (eigenfunctions). Each eigenmode is associated with a hydraulic diffusion time scale (eigenvalue) that depends on the intrinsic reservoir properties. The set of eigenmodes forms a basis of the solution space and the analytical solution shows some desirable properties: It is smooth, physically constrained for a closed system, and some parameters have a physical interpretation. As a result, in both single and multiwell problems, the late-time unit slope appears naturally and the curvature penalty does not have to be imposed, thus addressing current knowledge gaps. As an additional contribution, we also propose a mathematically well-defined expression in terms of eigenfunctions to the concept of investigated volume during a well test and a procedure for untangling the single-well deconvolved response from interference effects of neighboring wells under certain conditions. Applications to the analysis of drillstem tests (DST) and reservoir characterization are presented.
Waveform inversion of the ultra-long-period seismic event associated with ground tilt motion during an eruption of Mount Kusatsu-Shirane, Japan, on January 23, 2018
Authors: Takahashi Ryohei , Maeda Yuta , Watanabe Toshiki 
Published: February 2022

Abstract
We conducted waveform inversions of an ultra-long-period (~240-s) event associated with the phreatic eruption of Mount Kusatsu-Shirane on January 23, 2018. We used broadband seismic and tilt records from three stations surrounding the eruption site. The horizontal components of the broadband seismic records were severely contaminated by tilt motions. We applied a waveform inversion algorithm to account for both the translational and tilt motions. To reduce the number of free parameters, we assumed a tensile crack source and conducted grid searches for the centroid location and orientation of the crack. The results showed a rapid inflation of 105 m3 of the crack, followed by a slow deflation starting 8–11 s prior to the onset of the eruption. The source location and crack orientation were not uniquely determined. The most likely source is a north–south-opening sub-vertical crack near the eruptive craters. This ultra-long-period event may represent volcanic fluid migration from depth to the surface through a vertical crack during the eruption.

Published: February 2022

Abstract
Objective: To study the effect of problem-based learning (PBL) method in ultrasonography (US) resident standardization training during the COVID-19 pandemic.Methods: Forty-six residents were randomly divided into two groups to participate in a 30-day US training program. The residents in the observation group underwent the PBL combined with lecture-based learning (LBL) mode, while the residents in the control group participated in an integration of the LBL mode alone, with 23 residents in each group. The basic theoretical test, practical examination, and questionnaire were used to evaluate the teaching effect of the PBL+ LBL mode and the LBL mode alone. Results: The basic theoretical pre-test score of observation group had no significant differences with that of the control group. The post-test theoretical score and practical score were higher in the observation group than that of the control group with significant differences (P<0.01). The results of the questionnaire showed that resident’s satisfaction in the observation group with PBL combined with LBL method was 96%, which was significantly higher than that of the control group with LBL mode alone (80%) (P<0.05).Conclusion: The combination of PBL with LBL method has obvious advantages over the LBL mode alone in the training of US residents during the COVID-19 pandemic.

Authors: Hammoud Sahar , Amer Faten , Khatatbeh Haitham , Alfatafta Huda , Zrínyi Miklós , Kocsis Béla 
Published: February 2022

Abstract
Background
Up to our knowledge, there is currently no psychometrically validated Hungarian scale to evaluate nurses’ knowledge about infection prevention and control (IPC) practices. Thus, we aim in this study to assess the validity and reliability of the infection control standardized questionnaire Hungarian version (ICSQ-H).
Methods
A cross-sectional, multisite study was conducted among 591 nurses in Hungary. The original ICSQ included 25 questions. First, the questionnaire was translated into Hungarian. Then, content validity was assessed by a committee of four specialists. This was done by calculating the item content validity index and scale content validity index. Afterward, construct validity was evaluated in a two-step process using principal component analysis and confirmatory factor analysis. The goodness of fit for the model was measured through fit indices. Convergent validity was assessed by calculating the average variance extracted. Additionally, discriminant validity was evaluated by computing the spearman correlation coefficient between the constructs. Finally, the interitem correlations, the corrected item-total correlations, and the internal consistency were calculated.
Results
Content validity of the questionnaire was established with 23 items. The final four-construct ICSQ-H including 10 items showed a good fit model. Convergent validity was met except for the alcohol-based hand rub (ABHR) construct, while discriminant validity was met for all constructs. The interitem correlations and the corrected item-total correlations were met for all constructs but, the internal consistency of ABHR was unsatisfactory due to the low number of items.
Conclusions
The results did not support the original three-factor structure of the ICSQ. However, the four-factor ICSQ-H demonstrated an adequate degree of good fit and was found to be reliable. Based on our findings, we believe that the ICSQ-H could pave the way for more research regarding nurses’ IPC knowledge to be conducted in Hungary. Nevertheless, its validation among other healthcare workers is important to tailor effective interventions to enhance knowledge and awareness.

Abstract
Background: The incidence of any medical condition (e.g., sight, hearing, and speech problems, blackouts, chronic pain etc.) or disability (e.g., limited use of arms or fingers, legs, and feet, or other physical long-term health condition limiting everyday activities etc.) have been increasing among Australian children in recent decades. Objectives: This study assessed whether infant or child health characteristics might be predictors of subsequent medical conditions or disabilities in children in the first 15 years of life. Methods: Using time to event data of 5107 children, obtained from the Birth cohort of the Longitudinal Study of Australian Children, the study estimated the incidence of any medical condition or disability using the survival analysis technique. This study followed up the children from birth to 14 or 15 years of age (2004 - 2018) and assessed the association of infant and child health characteristics (birthweight, gestational age, use of intensive care unit or ventilator during their neonatal age and obesity) with hazard of any medical condition or disability using the random effect parametric survival regression model. The infant characteristics were measured in the Wave 1 while the children were aged 0/1 year and obesity characteristics were measured longitudinally over all the waves up to 14/15 years of age. Results: The hazard rate of any medical condition or disability for all participants was 26.13 per 1000 person-years among children in Australia. This hazard incidence was higher among low birthweight (39.07) and obese (34.37) children and among those who had received after‑birth ventilation or intensive care unit emergency services (36.87). The parametric panel regression model also suggests that children with low birthweight were 1.43 times (Hazard Ratio: 1.43, 95% Confidence Interval: 1.05 - 1.94) more likely to have any medical condition or disability than children with normal birthweight. The time to event analyses also revealed that being recipient of after-birth emergencies (HR: 1.47, 95% CI: 1.23 - 1.75), being male children (HR: 1.30, 95% CI: 1.14 - 1.48) or being obese (HR: 1.38, 95% CI: 1.07 – 1.79) significantly increased the likelihood of the incidence of a medical condition or disability among children. The regression model was adjusted for region of residence, language spoken at home, indigenous status, whether the study child has both parents, mothers age at birth and education of mothers.Conclusions: This study predicts the risk factors of any medical condition or disability among Australian children. The study findings suggest that infants with low birth weight, hospital emergency service use and children with obesity would benefit from additional health care monitoring to minimize the risk of any medical condition or disability.
