Authors: Gupta Sumedha , Solanki Shalu , Shamsunder Saritha , Ahuja Sana , Varma Vinayak 
Published: February 2024

Of all ovarian neoplasms, mature cystic teratomas make up between 10–20%. Malignant transformation accounts for just 0.1-2 percent of cases of adult teratoma. Malignant melanoma is one of the rarest metamorphoses. Here, we describe a postmenopausal woman who complained of abdominal pain. Upon examination, it was discovered that she had an abdominally metastasized mature dermoid cyst that had ruptured. Following an exploratory laparotomy and staging procedures, she had a total abdominal hysterectomy and bilateral salpingo-oophorectomy with removal of melanotic deposits from the pouch of doughlas, bladder peritoneum, mesentric, and omentum, as well as the small and large bowel serosa. Only roughly 45 cases of malignant melanoma originating in mature cystic teratomas in the ovary have been documented since 1901.

Published: February 2024

Objective:
Chest computed tomography (CT) scans are the gold standard for identifying pulmonary involvement in pneumonia-like COVID-19 cases, albeit with certain drawbacks such as radiation exposure and high costs. This research aims to evaluate the diagnostic precision of a 12-point lung ultrasound (LUS) against a low-dose chest CT scan in identifying lung lesions associated with COVID-19.

Methods:
The study incorporated 100 consecutive patients, aged over 18 years, exhibiting suspected clinical symptoms of COVID-19 or inpatients requiring a low-dose chest CT scan for diagnosing asymptomatic COVID-19 lung lesions. All participants underwent a 12-point LUS, followed by a low-dose chest CT scan. Data analysis was conducted using STATA-16, with descriptive results presented as mean and standard deviation.

Results:
The study comprised 60 males and 40 females, with an average age of 43.0±16.9 years. The mean distribution of the patients' clinical features was calculated. The LUS demonstrated a sensitivity, specificity, and positive and negative predictive values of 97.5%, 86.4%, 83.3%, and 98%, respectively.
Conclusion:
The 12-point LUS exhibited high sensitivity and specificity in assessing pulmonary involvement in COVID-19 patients. Therefore, lung ultrasound results, combined with medical history and clinical examination, can serve as an effective triage tool for COVID-19 patients. The LUS, a swift, safe, and effective ionization tool, can potentially replace chest CT scans in scenarios such as CT scan unavailability, intensive care management, and patient follow-up.

Objective: Reactive oxygen radicals are generated in the early stages of acute pancreatitis (AP) and are responsible for its progression. Thiol/disulfide homeostasis (TDH) is an important antioxidative mechanism. This study aimed to evaluate the role of TDH in the differential diagnosis of AP and predict its clinical severity.
Methods: Patients admitted to the emergency department due to upper abdominal pain were evaluated. The study consisted of two groups: the AP group and the non-AP group (patients with diagnoses other than AP). The AP group was divided into mild and severe according to Acute physiology and chronic health evaluation II (APACHE-II) scores. TDH was measured with an automated assay from Erel et al. Statistical analyses were done with SPSS 16.0.
Results: The results from 128 cases—58 in the AP group and 70 in the non-AP group—were evaluated. There was no difference in TDH parameters between the AP and non-AP groups. Among the AP subgroups, native thiol (sh) and total thiol (tt) were significantly lower in the severe AP group (sh: 313.9 μmol/L, 239.1 μmol/L; tt: 351.5 μmol/L, 303 μmo/L, respectively, in the mild and severe AP groups, P-value=0.006, P-value=0.013).
Conclusion: TDH parameters change because of inflammatory processes in AP. Since this change does not occur for any specific reason, using TDH parameters for differential diagnosis of AP in patients with upper abdominal pain is not appropriate. However, in patients already diagnosed with AP, native and total thiol levels might be helpful in the prediction of clinical severity with a limited role.

Objective: Trauma is one of the major causes of mortality and morbidity globally. The current study aimed to improve the understanding of characteristics, severity of injuries and outcomes of trauma patients admitted to Imam Khomeini Hospital, Urmia, Iran.
Methods: Data were obtained from the trauma registry of Imam Khomeini Hospital, a level 1 trauma referral center, for all patients admitted to the center from 17 september 2016 to 21 January 2023. Patients’ demographics, injury mechanisms, and patients' outcomes were analyzed.
Results: The emergency department attended to 5555 trauma patients. The gender distribution was with 3998 (71.9%) males and 1557 (29.1%) females. Patients' age ranged from 1 to 101 years, with a mean±standard deviation (SD) of 33.1 (±20.7) years. Road traffic accidents followed by falls were the most common causes of traumas reported in 2138 (38.5%) and 1298 (23.4%) trauma patients, respectively. The in-hospital mortality rate was 0.9% (53 patients). The mean (±SD) age of death was 43.5 (±22.4) years. 569 (10.2%) patients were admitted to the intensive care unit (ICU). The univariable logistic regression models showed that there were significant associations between age (P<0.001), Glasgow coma scale (GCS) (P<0.001), injury severity score (ISS) (P<0.001), and mechanical ventilation (P<0.001) as independent variables and death outcome. The univariable and multiple logistic regression analyses showed statistically significant associations between age, cause of trauma, ISS, GCS and body site injury with ICU admission. The odds of ICU admission in patients after being adjusted for age, ISS, GCS, cause of trauma and type of transportation was 1.73 times higher in head, face, and neck injuries compared to limb injuries. (adjusted OR: 1.73, [95% CI: 1.23,2.42]; P<0.01).
Conclusion: Older age, low GCS, higher ISS and mechanical ventilation were associated with higher mortality. Older age, higher ISS, lower GCS, body site injury, type of transportation, and cause of trauma were all significant independent predictors of ICU admission.

Abstract:
Objective: Wrist trauma is a common chief complaint in emergency departments and radiography is used to make the diagnosis. Excessive usage of radiographs would utilize resources, exert risk of radiation exposure, and overcrowding. Amsterdam wrist rules (AWR) have been proposed as a tool for clinical decision-making regarding the need for wrist fracture diagnosis. This study assessed the diagnostic test performance of this rule in wrist trauma for wrist fracture.
Methods: All patients over 18 years old with the chief complaint of acute wrist trauma were included. They were excluded if Glascow coma scale (GCS) was below 15, needed emergency surgery without an X-ray, and had a history of wrist fracture in the past 3 months. Anteroposterior and lateral radiographs were obtained and the AWR predictors were assessed before going to the radiology unit. The presence of a fracture of the distal radius was confirmed by treating emergency physician or radiologist.
Results: 205 participants were recruited in this study, of which 6 patients (2.9%) were excluded due to missing data. The median age was 40 (IQR: 30-50) and 74 (37.2%) patients were female. There were 66 (33.2%) patients with a wrist fracture, which distal radius accounted for most of them. The AWR had sensitivity and specificity of 0.71 (95% CI: 0.49,0.87) and 1 (95% CI: 0.92,1), respectively. Although the negative likelihood ratio of AWR was 0.29 (95% CI: 0.16,0.54), the positive likelihood ratio was infinite. The positive predicted value was 1 (95% CI: 0.80,1), whereas the negative predictive value was 0.86 (95% CI: 0.74,0.94).
Conclusion: The AWR showed great specificity and positive predictive. It had fair sensitivity, negative predictive value, and negative likelihood ratio for diagnosis of wrist fracture in patients with wrist trauma.
Tax Authorities and Local Government Development in Poland
Authors: Rogalska Joanna 
Published: February 2024

Purpose of the study: The purpose of this article is to examine the influence that tax authorities have had on the growth and progress of local governments in Poland. Through an analysis of the financial autonomy, degree of decentralisation, and local tax policy of Polish municipalities, this research endeavours to illuminate the correlation between tax authorities and the growth of local governments in Poland.
Methodology: This article conducts a comprehensive literature review on the subject of local tax competition studies in Poland. In addition, empirical experiments conducted on Polish data to determine the concept's applicability throughout the region are included.
Main findings: Based on the analysis, Poland holds a considerable level of financial autonomy, which is attributed to its authority in determining local tax rates and its freedom to finance investment initiatives. Moreover, research has revealed that the fiscal policies implemented by neighboring municipalities in Poland exert a substantial influence on the choices made by local legislators. This suggests that competition and local tax policy have a significant impact on the evolution of local administrations across the nation.
Application of the study: The findings of this study have significant implications for policymakers and local authorities in Poland. Understanding the impact of tax authorities on the development of local governments can help in formulating effective fiscal policies and strategies for sustainable development. By recognising the influence of tax regulations and revenue diversification on fiscal sustainability, policymakers can make informed decisions regarding local tax policies and financial autonomy.
Originality/Novelty of the study: In the article, the author emphasised the examination of the impact of tax authorities on the development of local governments in Poland, particularly in the context of the limited tax autonomy of Polish local authorities. The study delves into the unique challenges and opportunities that arise from this restricted tax autonomy and how it influences the fiscal sustainability and development of local governments in the country. Additionally, the analysis of the effects of municipal tax policy, including the influence of neighbouring municipalities' tax rates on local politicians' decisions, provides valuable insights into the dynamics of tax competition and its implications for local governance in Poland.

Performance Analysis of the Vortex Cuttings Cleaner: Turbine Hydraulic Drive and Cuttings Transport in Wellbore Annulus
Authors: Zhang Yiqun , Hu Zhaowen , Wang Qi , Huang Haochen , Liu Ya , Wang Wei 
Published: February 2024

Summary
In the process of directional and horizontal well drilling, cuttings tend to settle and form a bed at the low side of the annulus due to gravity, which decreases the drilling rate and even causes accidents in severe cases. This paper analyzes the performance of a new tool, the vortex cuttings cleaner, which can be effective without rotation of the drillpipe. Based on the computational fluid dynamics (CFD) approach, together with the discrete phase, Euler, and dynamic mesh models, the vortex cuttings cleaner is investigated with respect to the turbine torque, turbine velocity, pressure drop, and cuttings transport in the annulus. The working mechanism of the vortex cuttings cleaner is clarified. Finally, field tests are conducted on the tool to evaluate its application in terms of service life, wellbore friction, and rate of penetration (ROP). The results show that the turbine can rotate continuously under hydraulic drive. The turbine torque/velocity and the tool’s pressure drop increase with increasing displacement. The cuttings transport in the annulus is jointly affected by factors such as turbine velocity, fluid velocity, and particle size. A too low or high turbine velocity is unfavorable for cuttings transport. Through the analysis of the number of particles and particle concentration, the optimal velocity is determined to be 125 rev/min. The swirling flow intensity in the annulus flow field increases with the increase in turbine velocity. Field applications suggest a service life longer than 200 hours, a notable decrease in wellbore friction, and an average increase in ROP by more than 20%. This study provides a theoretical basis for the research on wellbore cleaning tools.

Summary
Injecting CO2 into reservoirs for storage and enhanced oil recovery (EOR) is a practical and cost-effective strategy for reducing carbon emissions. Commonly, CO2-rich industrial waste gas is used as the CO2 source, whereas contaminants such as H2S may severely impact carbon storage and EOR via competitive adsorption. Hence, the adsorption behavior of CH4, CO2, and H2S in calcite (CaCO3) micropores and the impact of H2S on CO2 sequestration and methane recovery are specifically investigated. The Grand Canonical Monte Carlo (GCMC) simulations were applied to study the adsorption characteristics of pure CO2, CH4, and H2S, and their multicomponent mixtures were also investigated in CaCO3 nanopores to reveal the impact of H2S on CO2 storage. The effects of pressure (0–20 MPa), temperature (293.15–383.15 K), pore width, buried depth, and gas mole fraction on the adsorption behaviors are simulated. Molecular dynamics (MD) simulations were performed to explore the diffusion characteristics of the three gases and their mixes. The amount of adsorbed CH4, CO2, and H2S enhances with rising pressure and declines with rising temperature. The order of adsorption quantity in CaCO3 nanopores is H2S &gt; CO2 &gt; CH4 based on the adsorption isotherm. At 10 MPa and 323.15 K, the interaction energies of CaCO3 with CO2, H2S, and CH4 are −2166.40 kcal/mol, −2076.93 kcal/mol, and −174.57 kcal/mol, respectively, which implies that the order of adsorption strength between the three gases and CaCO3 is CO2 &gt; H2S &gt; CH4. The CH4-CaCO3 and H2S-CaCO3 interaction energies are determined by van der Waals energy, whereas electrostatic energy predominates in the CO2-CaCO3 system. The adsorption loading of CH4 and CO2 are lowered by approximately 59.47% and 24.82% when the mole fraction of H2S is 20% at 323.15 K, reflecting the weakening of CH4 and CO2 adsorption by H2S due to competitive adsorption. The diffusivities of three pure gases in CaCO3 nanopore are listed in the following order: CH4 &gt; H2S ≈ CO2. The presence of H2S in the ternary mixtures will limit diffusion and outflow of the system and each single gas, with CH4 being the gas most affected by H2S. Concerning carbon storage in CaCO3 nanopores, the CO2/CH4 binary mixture is suitable for burial in shallower formations (around 1000 m) to maximize the storage amount, while the CO2/CH4/H2S ternary mixture should be buried as deep as possible to minimize the adverse effects of H2S. The effects of H2S on CO2 sequestration and CH4 recovery in CaCO3 nanopores are clarified, which provides theoretical assistance for CO2 storage and EOR projects in carbonate formation.
