Authors: Rasheed Farhan , Jamil Iqra , Tehseen Tahira , Yar Ahmad , Ali Farhana , Ashraf Ameena
Published: October 2023

Background and Objective: Typhoid fever caused by Salmonella typhi (S. typhi) is an important cause of morbidity and mortality worldwide. The emergence of resistance against the first and second line of drugs has limited the range of drug choices for its treatment. Therefore, the present study was designed to assess the status of drug resistance in S. typhi isolated from the blood samples of pediatric patients reporting at a leading tertiary care hospital in Lahore.

Methods: This descriptive study was conducted at the Pathology Department of Allama Iqbal Medical College, Lahore, Pakistan, over a period of 2 years. A total of 1,306 blood samples were aseptically collected from the pediatric population of Jinnah Hospital, Lahore, Pakistan, after obtaining informed assent from the parents/guardians. The samples were transferred into a Bact/Alert blood culture bottle. After the detection of microbial growth by the Bact/Alert 3-D system, bacterial isolates were identified by standard microbiological procedures. VITEK 2 compact automated identification and antimicrobial susceptibility testing instrument (bioMerieux) was used for the antimicrobial sensitivity testing. Data were entered and analyzed by using Statistical Package for the Social Sciences version 21.0.

Results: A total of 235 out of 1,306 (17.9%) blood culture samples yielded bacterial growth, among which 62.5% (n = 147) were S. typhi. Among 147 S. typhi isolates, 70.6% were multidrug resistant, while 63% were extensively drug resistant (XDR). Maximum resistance against first-line drugs observed was for ampicillin (79.4) and co-trimoxazole (67.2).

Conclusion: The emergence and spread of XDR S. typhi with a high level of resistance are quite alarming, leaving limited treatment options for the pediatric population. Moreover, increasing resistance to antibiotics demonstrates the quick waning of the efficacy of available first and second-line drugs in the treatment of typhoid fever.

The general budget is the link between the political system and the state's public finances. The political system is interesting in organizing and managing the governance, and the distribution of public authorities, and the relationship with individuals. As for public finance, it focuses on how to finance public services provided by the political authority to members of society. As political behavior affects the financial budget, the nature, size and type of Public revenues affect political behavior in them, so, the destabilized  political behavior in post-2003 period that applying no principles of good governance that characterized successive Iraqi governments, resulted in negative effects in the public budget (waste of public money, poor level of Transparency and accountability, and the delay in approving the general budget), and in addition led to the loss of confirmed revenues with inflation in operating expenses.
LA PAROLA DI DIO NELLE PRECES DEI VESPRI DELL’EPIFANIA
Authors: Superson Jarosław
Published: October 2023

Preces are the prayers that in modern Liturgy of the Hours are recited during Morning Prayer (invocationes) and Vespers (intercessiones). For centuries they were usually composed of psalm verses quotes and placed in different canonical hours. Contemporary preces created after the Second Vatican Council by Coetus XII bis are generally not. The author of the presentation entitled “The Word of God in the preces of the Vespers on Epiphany”, considering the record of Sacra Congregatio pro Cultu Divino, Commissio specialis ad instaurationem liturgicam absolvendam, Schemata n. 348, pointed out some expressions and phrases in verses 2, 6, 7, 12 i 17 of Psalm 71, which belongs to royal prayers, as the biblical source for preces on the Feast of Epiphany. The result of his research is an observation that Scriptura crescit cum orante, not only during reading of the text but above all as the updating in the course of the rite, which dynamism feeds the prayer so lavishly that the Word of God becomes his own and motivates him to compose a personal prayer.

Literature at the service of truth: Simone Weil and 'L’Enracinement'
Authors: Doering E. Jane
Published: October 2023

The purpose of this article is to elaborate the many literary allusions that Simone Weil used in her ultimate work: L' Enracinement, translated as The Need for Roots, to achieve her goal of encouraging her fellow countrymen to create a new postwar society. Understanding how she used the riches of the French and Western Literary Cannon, less easily grasped by those not educated in the French Education system, enriches the understanding of Weil's purpose and skill in writing on many levels, simultaneously for different target audiences. Underlying her stress on the need for truth and honesty about a county's past and present, with discernable respect for every person, is her foundational belief in the spiritual destiny of every human being. Examining her literary allusions in detail to show her clever subversion of traditionally accepted interpretations brings a new dimension to Simone Weil studies, while underlining the relevance of this essay to contemporary dilemmas.
Action, transcendance, incarnation. Pour une lecture unifiée de la pensée politique de S. Weil
Authors: Gabellieri Emmanuel
Published: October 2023

In contrast to the readings that oppose a first 'revolutionary' Simone Weil to a second 'conservative' Simone Weil, this article supports the thesis of a profound continuity and coherence in Weil's political thought, parallel to the overall unity of her philosophy. Just as there is no opposition between her political thought of the early and the late 1930s, there is no opposition between her 'mystical' philosophy from the period in Marseille and her "political" philosophy from the period in London.  However, this does not abolish the distance that must be maintained between religion, mysticism and politics, because the "synthesis" of these levels is not historical-political, but eschatological. Ultimately, we show that Weilian thought supports both the dual necessity and the mutual insufficiency of mysticism and politics, which enables it to escape both totalitarian idolatry and the mysticism of a pure afterlife. If she ignores the opposition so common in modern thought between "Amor Dei" and "Amor Mundi", it is because she wishes to comply with the dual Platonic and Christian injunction to bring the Good down into necessity without confusing both, thus making political action the criterion of truth of political thought.
Logistic regression model for predicting failure of dual antihypertensive therapy: a prospective comparative non-randomized clinical trial
Authors: Okorokova T. O. , Kryuchkova O. N.
Published: October 2023

Background. Initial dual antihypertensive therapy is currently considered as the first management step for the majority of patients with arterial hypertension. However, it often fails to achieve the target blood pressure levels. An approved algorithm for predicting the failure of dual antihypertensive therapy is still to be developed. Objectives. To establish predictors of dual antihypertensive therapy failure in patients with high and very high cardiovascular risk and to create a model for predicting negative outcome of dual antihypertensive therapy. Methods. The paper presents a prospective comparative non-randomized clinical trial. The recruiting of participants and recording of results were carried out in March–December 2019 with 3 months of the follow-up period. The trial involved examination of 88 patients with poor blood pressure control, stage II and III arterial hypertension, high and very high cardiovascular risk of stages 1–3. Clinical and laboratory examination was carried out in compliance with the current regulatory documents. Additional examination included tests for uric acid, high-sensitivity C-reactive protein, as well as respiratory polygraphy and computerized capillaroscopy. All patients were prescribed dual antihypertensive therapy. The primary search for predictors was performed using the binary logistic regression. The predictive model was developed by stepwise variable selection. The diagnostic significance of the binary classifier was assessed by means of ROC-curve analysis; the calculation was performed using MedCalc 20.218 software (MedCalc Software Ltd., Belgium). Results. Administration of two hypotensive drugs appears to be effective in 33% of patients. The final model for predicting negative outcomes of dual antihypertensive therapy included such independent predictors as interventricular septal thickness, daily mean systolic blood pressure, and area density of the capillary network. The odds ratio accounted for 9.1 (95% confidence interval 3.12; 26.82). The area under the ROC curve based on the multiple binary logistic regression model comprised 0.805±0.05 with 95% confidence interval: 0.707-0.882 (p<0.0001). The sensitivity and specificity of the method amounted to 83.1 and 69.0%, respectively. The prediction accuracy comprised 77.3%. Conclusion. The development of patient-oriented algorithms for selection of hypotensive treatment is considered to be essential due to poor blood pressure control during dual antihypertensive therapy. The developed prognostic model may be applied when managing hypertension.

Authors: Hardas Varsha Suhas , Mane Anupama , J Punya , Paulraj Reena
Published: October 2023

Cavernous hemangioma of the breast is a rare benign vascular tumor, whose clinical diagnosis is challenging. We describe a case of cavernous hemangioma in an 81-year-old female, who presented with a history of a slow-growing lump in the left breast from the past few months. Mammography revealed a circumscribed high-density mass with microlobulated margins in the lower outer quadrant with no associated findings. Targeted sonography revealed an isoechoic heterogeneous solid mass in the subcutaneous plane with no associated vascularity on color doppler. It was assigned as BI-RADS IV B and an image-guided core biopsy was done. The histopathology report was of cavernous hemangioma. A close follow-up was advised.

Quality Assurance in Breast Imaging is one of the cornerstones for providing high-quality breast care. It is central to achieving and maintaining high standards of breast radiology services. Uniform guidelines for the entire nation ensures that high standards can be achieved irrespective of geographical location of the imaging center and financial capability of the patient. No consensus document or guidelines focuses on Indian patients and its healthcare infrastructures. In this document, a task group formed by the Breast Imaging Society, India (BISI), sought to formulate quality assurance standards for all breast imaging modalities available in India. A breast imaging framework, practicable for all breast radiologists and institutions, has been provided to establish the minimum quality standards required for breast imaging services. The guidelines encompass all aspects of breast imaging, including mammography, breast ultrasound, breast magnetic resonance imaging, and breast interventions. The recommended reporting format for various modalities is also included. The guidelines also provide the minimum training requirement for all members of the breast imaging service provision team, including radiographers and radiologists. The minimum standards for the equipment, as well as the unit, have also been addressed. The current quality assurance guideline aims to provide a holistic approach to standardize breast care imaging services in India.
Rare breast cancers with seemingly benign features on conventional imaging: Radio-pathological correlation and review of literature
Authors: Sudhir Rashmi , Kodandapani Suseela
Published: October 2023

Oval or rounded breast masses with circumscribed margins, absence of microcalcifications, and architectural distortions are usually benign. However, 10-20% of breast cancers may have circumscribed margins, which may be misdiagnosed as benign breast mass or lead to delayed diagnosis in advanced stages of cancer. Most frequently, circumscribed breast cancers are high-grade invasive ductal carcinoma of triple-negative molecular subtype. However, there are many other rare histological subtypes of cancers in the breast with circumscribed margins or less aggressive features on imaging and mimic benign breast lesions. A radiologist needs to be familiar with the imaging features of various atypical malignant breast tumors to avoid delay in diagnosis. These rare malignant breast tumors are mucinous carcinoma, papillary carcinoma, lymphoma, leukemia, myeloma, metastasis from extramammary primaries, adenoid cystic carcinoma, signet-ring carcinoma, malignant phyllodes tumor, mesenchymal sarcoma, Ewing’s sarcoma, and medullary carcinoma. This pictorial review illustrates the clinical, multimodality imaging features of rare malignant breast tumors with less aggressive features on conventional breast imaging with pathological correlation.
A rare cause of low back pain in adolescence – Bertolotti syndrome: A case report
Authors: Ali Mustafa , Enchev Yavor
Published: October 2023

Background:

Bertolotti syndrome (BS) is defined as a congenital anomaly of the spine that includes sacralization of the lowest lumbar vertebra or lumbarization of the first sacral vertebra (i.e., lumbosacral transitional vertebra- LSTV) and the pain associated with this condition. The incidence of BS in adolescence is rare; we found only three such case reports of patients under the age of 18 in the literature, here will add a fourth.

Case Description:

A 17-year-old female presented with a 2-month history of low back pain exacerbated by physical activity. Her neurological examination was normal, except for pain elicited when applying pressure over the sacroiliac joints bilaterally, and over the spinous process of the L5 vertebra. The computed tomography scan documented BS: (i.e., LSTV – Castellvi classification: Type IIa on the left side). She was successfully treated with nonsteroidal anti-inflammatory drugs (NSAIDs) alone.

Conclusion:

Here, we report a 17-year-old female who was symptomatic from BS and was successfully treated with NSAIDs.
Study of non-radiation cataract risk factors in chronically exposed persons
Authors:   Urals Research Center for Radiation Medicine (URCRM), Chelyabinsk, Russian Federation, Mikryukova L.D.
Published: October 2023

Relevance. Epidemiological data have revealed a significant association between exposure to ionizing radiation, loss of lens optical function, and cataract formation. Cataract is a multifactorial disease that is traditionally associated with age, exposure to ultraviolet radiation, diabetes, smoking, alcohol abuse, obesity, steroid hormones, hypertension, etc. The chronic nature of the effects of radiation on the body, including both cell damage and regenerative processes, complicates the issue of assessment of the nature and magnitude of the dose-dependence of effects. Purpose. To investigate the potential risk factors of cataract development in different morphological layers, depending on social conditions and several diseases (non-radiation factors) in the population affected by two radiation accidents (dumping of radioactive waste into the Techa River and the East Ural Radioactive Trace) in the Southern Urals. Material and methods. The data from an in-depth examination of patients by an ophthalmologist in the Clinical Department of the URCRM were analyzed. The study involved 1377 patients. The «case» and «control» groups, comparable in sex and age, were selected from the general population. The impact of each factor was assessed on the basis of the Odds Ratio (OR) indicator. Risk factors associated with the development of cataracts in different layers of the lens included arterial hypertension, body mass index, age at the onset of exposure, level of education, alcohol consumption, smoking, ethnicity. Results. An increased risk of developing cataracts in the lens nucleus (1st sample: OR=0.54 (1st sample: 95% CI: 0.34–0.86; 2nd sample: OR=0.51 (95% CI: 0.32–0.82) (p<0.05)) and the intensity of its color (1st sample: OR=0.48 (95% CI: 0.29–0.80); 2nd sample: OR=0.56 (95% CI: 0.34–0.94) (p<0.05)) was established in persons who were at the age over 6 at the onset of exposure. Conclusion. The analysis did not reveal a statistically significant relationship of changes in the cortical layers, the nucleus and the posterior capsule of the lens with other studied risk factors in persons exposed to chronic radiation at a low to medium dose range. There was an increased risk of cataract development in the lens nucleus and the intensity of its color in persons who began to be exposed at the age of over 6 years. Key words: risk factors, cortical cataract, nuclear cataract, posterior subcapsular cataract, chronic exposure
Clinical efficacy of cataracts surgical treatment in patients after ARK using IOL power calculation basic formulas
Authors:   S. Fyodorov Eye Microsurgery Federal State Institution, Irkutsk Branch, Irkutsk, Russian Federation, Tsirenzhapova E.K. , Rozanova O.I. ,   S. Fyodorov Eye Microsurgery Federal State Institution, Irkutsk Branch, Irkutsk, Russian Federation

Purpose. To analyze possible refractive errors when calculating IOL power in patients after ARK (anterior radial keratotomy). Material and methods. The data of Intraocular lens (IOL) power calculation in 46 patients (46 eyes) with anterior radial keratotomy (ARK) who also underwent cataract surgery were analyzed. The IOL calculation was performed taking into account the data obtained by the Lenstar LS 900 (HAAG-STREIT AG, Switzerland) and keratotopography (Pentacam HR, Oculus, Germany), with a target refraction corresponding to emmetropia up to ±0.50 D. Results. The analysis of the clinical efficacy of phacoemulsification with IOL implantation in patients after ARK with the refractive error (RE) calculation and refractive prediction error (RPE) calculation according to the basic formulas were performed. It was found that emmetropia (up to ±0.5 D) in the postoperative period was achieved in 52% of cases. The value of the postoperative RPE had no reliable dependence on the values of the eyeball length, it was depended on the corneal optical power in the central zone of the cornea only with some formulas for IOL calculation (Barrett, Barrett Universal II, MIKOFRK/ALF). The obtained results of the analysis provide justification for a deeper study of post keratotomy corneal deformation as a pathological condition with the presence of hidden risk factors. Conclusion. Phacoemulsification with IOL implantation in patients with previously performed ARK is accompanied by the achievement of target refraction in 52% of cases. The high proportion of IOL calculation errors in cataract surgery in patients after ARK largely depends on hidden factors, which determines the need for a detailed study of post keratotomy corneal deformation as a pathological condition. Key words: IOL power calculation, anterior radial keratotomy, emmetropia

Selain itu, protokol MQTT juga dibandingkan dengan protokol HTTP untuk melihat efisiensi dari kecepatan respon time dan latency saat pengiriman data ke server. Perbandingan waktu respon antara MQTT dengan HTTP untuk pengiriman data ke server setiap 1 jam adalah 0.08 detik (MQTT) dan 0.4 detik (HTTP). Kemudian, perbandingan antara pengiriman data ke server setiap 10 menit adalah 0.04 detik (MQTT) dan 0.5 detik (HTTP). Selanjutnya, perbandingan antara pengiriman data ke server setiap detik adalah 0.08 detik (MQTT) dan 1.12 detik (HTTP). Hasilnya, pengiriman data menggunakan protokol MQTT lebih stabil dan waktu responnya lebih cepat dibandingkan dengan HTTP.

Increased public activity in cyberspace (Internet) during the Covid-19 pandemic has also increased cybercrime cases with various attack targets, including E-Government services. Cybercrime is hidden and occurs unnoticed in E-Government, so handling it is challenging for all government agencies. The characteristics of E-Government are unique and different from other service systems in general, requiring extra anticipation for the prevention and handling of cybercrime attack threats. This research proposes log and event data analysis to detect cybercrime in e-Government using System Information and Event Management (SIEM). The main contribution of this research is a simple, fast, and accurate cybercrime detection process in the e-Government environment by increasing the level of log and event data analysis with the SIEM approach. SIEM technology based on machine learning and big data is implemented with Elastic Stack. The implemented technique can be used as a mitigation program against cybercrime threats that often attack and target e-Government. With simple, accurate, and fast cybercrime detection, it is expected to improve e-Government security and increase public confidence in public services organized by government agencies.

Instagram adalah salah satu media sosial yang populer di Indonesia dan memiliki resiko terjadinya cyberbullying, sehingga klasifikasi komentar cyberbullying perlu dilakukan menggunakan text mining. Model klasifikasi yang dibangun pada penelitian ini menggunakan Neural Network dengan arsitektur Multilayer Perceptron dan dilatih dengan algoritma Backpropagation. Bayesian Optimization digunakan untuk melakukan optimasi hyperparameter, dengan hyperparameter yang dioptimasi adalah hidden layer, learning rate, dan momentum. Dilihat dari hasil evaluasi, performa dari model Neural Network dengan optimasi hyperparameter lebih baik daripada Neural Network yang hanya menggunakan default hyperparameter. Dimana model Neural Network dengan default hyperparameter mengalami overfitting dan menghasilkan nilai akurasi sebesar 81,38%, sedangkan model dengan optimasi hyperparameter tidak mengalami overfitting dan mengalami kenaikan akurasi dibandingkan dengan model Neural Network tanpa optimasi hyperparameter dengan model dengan tiga hyperparameter yang dioptimasi yaitu hidden layer, learning rate, dan momentum mengalami kenaikan akurasi sebesar 2,5%, model dengan optimasi hyperparameter pada hidden layer dan pada learning rate masing-masing mengalami kenaikan akurasi yang sama, yaitu sebesar 2,37%, dan model dengan optimasi hyperparameter pada momentum mengalami kenaikan akurasi sebesar 2%. Hasil penelitian ini menunjukkan bahwa hidden layer, learning rate, dan momentum ketika di optimasi secara bersamaan memiliki pengaruh besar dalam mencegah overfitting, menaikan akurasi, dan memiliki waktu eksekusi yang baik daripada dioptimasi secara terpisah.

Penambahan Particle Swarm Optimization sebagai seleksi fitur pada kasus  disimpulkan efektif mempertahankan kinerja pembelajaran model dilihat dari nilai AUC yang tetap berada pada kategori Good Classification saat dilatih dengan fitur kata yang lebih sedikit.
Hierarchical clustering of chemical space using binary-encoded SMARTS for building data-driven chemical perception models
Authors: Gokey Trevor , Mobley David L.
Published: October 2023

Molecular mechanics force fields require a chemical perception model to assign parameters to molecules. A recent advancement in force fields is the use of the SMARTS substructure query language as the perception model. Although it is straightforward to write SMARTS patterns to define new force field parameters, it is difficult to manually determine the particular patterns needed to improve performance. Here we present a scheme to automatically generate SMARTS patterns that partitions the data according to a given objective. From this operation we describe how hierarchies of SMARTS patterns can be generated from the input data. Such hierarchies can be used for building force fields from scratch or improve upon established ones. We test our methods by building SMARTS hierarchies that map SMARTS patterns to existing force fields such as GAFF and Sage which allows us to test that our approach can recognize the chemical substructures typically used by human-designed force field perception models. We then build a SMARTS hierarchy that clusters bonds based on quantum mechanically-derived bond lengths which demonstrates the possibility of creating novel force field chemical perception models.
The influence of dangerous geological and technogenic processes during engineering and geological research and environmental safety for construction in the modern period

Published: October 2023

Problems Statement and Purpose. Reliability of construction, protection of the territory from dangerous geological and technogenic processes, assessment of impact of construction and reconstruction objects on the environmental safety of the territory should be based on high-quality materials of engineering investigations. Today in Ukraine, the conditions of construction and reconstruction have significantly increased the requirements for the quality and composition of engineering research. At the same time, there are a number of natural and social factors that increase the degree of geotechnical and environmental risks during construction, there is no system that ensures the mandatory implementation of state regulations, which has an extremely negative effect on the quality of research materials. These questions are of particular importance given the volume of work that awaits us in the reconstruction of our country.

The purpose of article is to once again draw attention to the problems in the field of engineering and geological investigations for construction, which largely depend on the safety and comfort of our living, to formulate proposals for improving the state of affairs in anticipation of the large-scale recovery of our country and the possibility of entering the regulatory field of the EU.

Data & Methods. The legislative framework of Ukraine in the field of engineering and geological investigations for construction has been analyzed.

Results. The article provides an analysis of the state with the legislative base in Ukraine regarding engineering surveys, the system that ensures mandatory compliance with the requirements of regulatory documents, factors that increase man-made and environmental risks in construction, proposed measures aimed at improving the quality of survey materials. 4 factors have been established that systematically affect the quality of engineering and geological investigations and the safety of construction: 1) most accidents and deformations of buildings and structures are associated with processes in the "base - foundation" system; 2) about 80% of the territory of Ukraine is characterized by complex engineering and geological conditions, with manifestations of almost all dangerous geological processes: seismicity, karst, landslides, reworking of banks, subsidence, soil swelling, etc.; 3) a significant increase in the specific weight of construction in conditions of dense urban construction and reconstruction of existing buildings in the total volume of construction; 4) social and economic conditions. An example of a change in the qualitative characteristics of underground hydrosphere (chemical composition and increase in the aggressiveness of groundwater), which had an impact on the reliability of construction and the ecological component at the studied area, has been considered.
