Lay Beliefs And Responses Concerning Hypertension And Its Management In Two Culturally Distinct Groups
Authors: Mhlongo S.W.P.
Published: October 2024

Objective: To determine quantitatively whether there are significant differences in lay beliefs about hypertension and its management between African- Caribbean (A.C.) living in the UK but born in the West Indian Caribbean Islands and white hypertensive patients in the UK.Design: Self-administered postal (and surgery) questionnaire.Setting: Two general practices in the Wembley / North London and Dagenham (Essex) areas.Participants: Male and female patients aged between 35 and 69 years of age registered with the above practices and receiving treatment for hypertension. These were selected from the age/sex/disease registers.Interventions: NoneMain outcome Measures: African-Caribbean vs. White/Caucasian responses to the 16-item questionnaire and determining statistical significance (the P value). This was done to determine whether or not there are significant differences in lay beliefs between the two ethnic groups i.e.A.C. versus white Caucasian.Results: Out of 525 patients who were sent the 16-item questionnaire, there were 427 responses (238 men, 189 women). This was an 81% response rate. In terms of race, there were 224 white and 203 African-Caribbean respondents. The responses to the questions strongly suggested that there are significant ethnic differences on matters of lay beliefs regarding hypertension and its management. This quantitative study supported the findings and conclusions of a previous (1988) qualitative one by Myfawny Morgan and C.J.Watkins on the same subject.Conclusions: Lay beliefs appear to be extremely important amongst all cultures and it would appear that these do have an impact on how an individual views his or her medical condition and how the doctors manage it. Intercontinental and international encounters appear to be here with us to stay due to a variety of factors e.g. trade, education, sports and wars. It is therefore of utmost importance that medical practitioners bear this in mind in their encounters with patients. An acceptance of this approach by all doctors and health workers may improve compliance.

\mathrm{Plov}(f)

of

WOMAN GEOGRAPHER FORGED FROM FIRST-HAND EXPERIENCES IN THE BRAZILIAN NORTHEASTERN DRYLANDS
Authors: Silva José Borzacchiello da
Published: October 2024

The article follows the paths of Mrs. Maria Geralda, a geographer forged from first-hand experiences in the so-called "sertão" (drylands in the Northeast of Brazil). It highlights, mainly, her stay in the state of Ceará, very expressive for the construction of her professional profile. In Ceará, she experienced dividing herself between the institutional academic life and the political militancy based on geographic knowledge. It also focuses on the places of her comings and goings around the world. Maria Geralda sensed, from the sea, the need to better understand the "sertão", her other passion. She used to claim that the construction of the geographic knowledge and the causes of its subjectivity result from a transposition of an image of objects, practices and spatial processes, and consists in the coherent selection of certain elements considered relevant, to the detriment of others. This pathway she didn't tread alone. Each year, those who approached her formulations and guidelines grew in number. More than a homage, the text is the expression of affection, tenderness, and admiration. Keywords: Homage, Trajectory, Geographic Knowledge.

Published: October 2024

The modeling of areas susceptible to soil loss due to hydro-erosive processes consists of methods that simplify reality to predict future behavior based on the observation and interaction of a set of geoenvironmental factors. Thus, the objective of the current analysis is to predict susceptibility to soil loss and map areas with the potential risk of erosion using the principles of Binary Logistic Regression (BLR) and Artificial Neural Networks (ANN). The hydrographic sub-basin of the Sete Voltas River (330 km2), Rondônia, Brazil, was defined as the experimental area. Models were obtained using 100 sample units and 14 predictor parameters. Susceptibility was mapped based on five reference classes: very low, low, moderate, high, and very high. ANN obtained an area under the curve (AUC) of 0.808 and global precision of 79.2%, and the BLR model showed an AUC of 0.888 and global precision of 77%. Potentially susceptible areas represent 57.71% and 54.80% of the area for BLR and ANN models, respectively. The greatest potential risks are verified in places with no vegetation cover associated with agricultural practices. The technique proved to be effective, with adequate precision and the advantage of being less time-consuming and expensive than other methods. Keywords: Binary Logistic Regression; Artificial Neural Network; Erosion Susceptibility.
YESTERDAY AND THE TODAY OF THE GEOGRAPHIC NAMES OF THE IMPERIAL CITY OF PETRÓPOLIS/RJ
Authors: Laeta Tainá , Fernandes Manoel Couto
Published: October 2024

Historical Cartography along with Historical Toponymy makes it possible to understand the dynamics of geographic space through the occupation process, that is, historical maps contribute to the toponymic study, where geographic names present themselves as testimonies in the process of occupation of a given territory and space dynamics geographical. In this sense, the objective of the present work is to analyze the spatial dynamics regarding the origin of the geographical names of the genesis area of the imperial city of Petrópolis/RJ. For this purpose, it relied on the historical cartographic documents Koeler Map – 1846 and Otto Reimarus Map – 1854, and the cartographic base from 1999. Thus, the geographic names contained in the three referred cartographic documents were extracted and subsequently classified. Results show the prevalence of geographic names of Germanic and Portuguese origin, however, the names of Germanic origin went out of use over time. These geographical names of Germanic origin are closely related to the settlers who established themselves there in the mid-nineteenth century. However, the town was later occupied by, individuals of Portuguese origin, which is also associated with the creation of different entrances to the city and explains the modification of these names. Keywords: Historical Cartography. Historical Toponymy. Koeler Map. Otto Reimarus Map.

Published: October 2024

The present research analyzed the effect of relief on the variability and extremes of rainfall in the central portion of the state of São Paulo, using 31 surface rainfall gauges. For this, it applied the methods of filling gaps (Regional Weighting), rainfall classification (Rain Anomaly Indexes) and precipitation indexes (Rclimdex). Through the methods used, it was verified that the pluviometric variability showed in the admitted parameters of normality with about 17% of the years, in the wet parameters about 18% of the years and in the dry parameters about 15% of the years of the historical series of 1979 -2017. In addition, it was found that among the thirty-eight years of the historical series, the year 1983 was the wettest and the year 2014 the driest. As these were two distinct representative years (wet and dry) of rainfall, it was noted through the rainfall indexes, they showed the strength of the orographic effect in the intensification of rainfall in volume and number of extreme days in the higher regions located in the southern portion of the study area. Therefore, due to the altitude that manifests itself associated with a sharp altimetric difference that establishes a high slope, which the central region of the state of São Paulo has, its morphological characteristics play an important role with the process of intensification of the rains, mainly in the years rainy. Keywords: Precipitation; Rainfall anomaly index; Extreme years; RClimdex; Relief.
Unveiling the clinicopathological enigma of crawling-type gastric adenocarcinoma
Authors: Christodoulidis Grigorios , Agko Sara E , Kouliou Marina N , Koumarelas Konstantinos E
Published: October 2024

In this editorial we comment on the article by Xu et al . Gastric adenocarcinoma (GA) is a malignancy which arises from the gastric mucosa and encompasses heterogenous tumors with varying characteristics. There are two main classifications: Lauren’s and the World Health Organization distinguishing the diverse types of GA depending on clinical, genetic, morphological and epidemiological features. “Crawling-type” adenocarcinoma (CRA) is a subtype characterized by irregularly fused glands with low-grade cellular atypia. Moreover, CRA represents differentiated tumor cells resembling intestinal metaplasia which results in misdiagnosis. The diagnosis is of utmost importance, as well as the subclassification and thorough pathological assessment. With regard to the symptoms of GA, these depend on the stage of the disease. Diagnostic methods play a crucial role in assessing the extent of the tumor and the stage of the disease. Nevertheless, early detection of CRA remains challenging due to its histological features. In summary, CRA is a distinct type of GA with particular clinicopathological and histological characteristics. Despite its significance, it not distinguished as a subtype, resulting in diagnostic challenges. Diagnosis is based on careful observation and thorough biopsy analysis, indicating the importance of comprehensive pathological assessment.
Drug-eluting beads chemoembolization combined with programmed cell death 1 inhibitor and lenvatinib for large hepatocellular carcinoma
Authors: Yang Hui , Qiu Guang-Ping , Liu Jie , Yang Tie-Quan
Published: October 2024

BACKGROUND

The combination of transarterial chemoembolization (TACE), lenvatinib, and programmed cell death 1 (PD-1) inhibitor has been widely used in the treatment of advanced hepatocellular carcinoma (HCC) and has achieved promising results. However, there are few studies comparing whether drug-eluting beads TACE (D-TACE) can bring more survival benefits to patients with large HCC compared to conventional TACE (C-TACE) in this triplet therapy.

AIM

To compare the efficacy and adverse events (AEs) of triple therapy comprising D-TACE, PD-1 inhibitors, and lenvatinib (D-TACE-P-L) and C-TACE, PD-1 inhibitors, and lenvatinib (C-TACE-P-L) in patients with large HCC (maximum diameter ≥ 5 cm), and analyze the prognostic factors.

METHODS

Following a comprehensive review of our hospital’s medical records, this retrospective study included 104 patients: 50 received D-TACE-P-L, and 54 received C-TACE-P-L. We employed Kaplan-Meier estimation to assess the median progression-free survival (PFS) between the two groups, utilized Cox multivariate regression analysis to identify prognostic factors, and applied the χ 2 test to evaluate AEs.

RESULTS

The objective response rate (ORR) and median PFS were significantly higher in the D-TACE-P-L group compared to the C-TACE-P-L group (ORR: 66.0% vs 44.4%, P = 0.027; median PFS: 6.8 months vs 5.0 months, P = 0.041). Cox regression analysis identified treatment option, portal vein tumor thrombus, and hepatic vein invasion as protective factors for PFS. AEs were comparable between the two groups.

CONCLUSION

D-TACE-P-L may have significantly better PFS and ORR for large HCC, while exhibiting similar AEs to C-TACE-P-L.

Published: October 2024

BACKGROUND

Gastric cancer (GC) endangers the survival and prognosis of patients worldwide. Improving the prognosis of patients with early GC (EGC) is crucial to prolong their survival time.

AIM

To analyze the effects of endoscopic submucosal dissection (ESD) on gastrointestinal function and nutritional status in patients with EGC.

METHODS

Eighty patients with EGC between January 2021 and January 2024 were divided according to different surgical protocol into following two groups: 42 patients who underwent ESD in the ESD group and 38 patients treated with endoscopic mucosal resection (EMR) in the EMR group. Two groups were compared in the operative indices, lesion resection rate, postoperative recovery of gastrointestinal function, nutritional status, and incidence of surgical complications.

RESULTS

The overall resection rate of the lesion in the ESD group was higher. The operative bleeding volume and operation time were higher and gastrointestinal ventilation time was shorter in the ESD group than those in the EMR group (P < 0.05). The nutritional statuses of the two groups decreased after operation; however, the levels of albumin, prealbumin, hemoglobin, and transferrin were higher in the ESD group than in the EMR group (P < 0.05). The post-operative pepsinogen (PG) I level in the ESD group was higher than that in the EMR group, and the PG II level was lower than that in the EMR group (P < 0.05). The incidence of postoperative complications was compared between the two groups (P > 0.05).

CONCLUSION

ESD can promote the immediate recovery of patient’s postoperative gastrointestinal function, improve their nutritional level, and signifies its application in patients with EGC.

Published: October 2024

BACKGROUND

Aggressive primary gastrointestinal non-Hodgkin lymphoma (PGINHL) is an uncommon and heterogeneous group of lymphoid malignancies, that differs from indolent lymphoma and has a high incidence of severe gastrointestinal complications (GICs).

AIM

To investigate and compare the clinicopathological characteristics, treatments and outcomes in the GICs and No-GICs group with aggressive PGINHL.

METHODS

This retrospective analysis was performed on aggressive PGINHL patients between January 2013 and December 2021 at our hospital. The independent influence factors of GICs were obtained by univariate and multivariate Logistic regression analysis, the selected variables significantly related to GICs were selected as the final predictors to construct nomogram. Kaplan-Meier curves further analyzed the survival of patients in GICs and No-GICs groups. Survival analysis of GICs group was performed using Cox regression.

RESULTS

We focused on 124 aggressive PGINHL cases, which had a relatively high incidence 48.4% (60/124 cases) of GICs, the most common histological type in GICs group was diffuse large B-cell lymphoma (DLBCL) (n = 49, 81.7%). In the GICs group, small intestine was the most common anatomic site of lesion (43.3%), followed by large intestine (31.7%), and then stomach and esophagus (25.0%). Multivariate Logistic regression analysis showed that the independent risk factors for GICs were the small intestine [odd ratio (OR) = 3.33; 95% confidence interval (CI): 1.47-9.41; P = 0.009), aggressive B-cell (OR = 0.09; 95%CI: 0.01-0.83; P = 0.033), maximum tumor diameter (OR = 1.25; 95%CI: 1.07-1.47; P = 0.005), invaded deep serous layer (OR = 3.38; 95%CI: 1.24-9.19; P = 0.017). We developed a nomogram to predict risk of GICs in aggressive PGINHL patients based on independent risk factors. The value of area under curve calculated by receiver operating characteristic curve was 0.815, and calibration curve and decision curve analysis further indicated that the prediction effect was superior. The majority of patients with GICs were given combination therapy (chemotherapy combined with surgery or radiation). Event-free survival and overall survival in GICs group were no worse than those in the No-GICs group.

CONCLUSION

The complication rate of GICs in patients with aggressive PGINHL was relatively high, particularly in PGI-DLBCL. The independent risk factors for GICs were the small intestine, PGI-TNKL, bulky tumor, and depth of invasion. A combination treatment, involving surgery, improved survival in the GICs group.

Vitamin D is an essential micronutrient that is involved in numerous biological processes. It not only keeps bones healthy, but also has a protective effect on the cardiovascular system, the pancreas and fatty tissue. Around 50% of the world’s population suffers from vitamin D deficiency or insufficiency. The prevalence of these diseases is significantly higher in obese people, regardless of age and place of residence. The presence of polymorphisms in the VDR gene (vitamin D receptor) can explain individual differences in the concentration of vitamin D 25(OH) in blood serum. Of particular interest are the effects of the polymorphisms rs731236 and rs2228570 on vitamin levels. Thus, the VDR polymorphism rs731236 is a synonymous substitution, whereas the polymorphism rs2228570 is a non-synonymous substitution. The article investigated the polymorphisms of the VDR gene rs2228570 (T/C), rs731236 (T/C) and determined their association with blood vitamin D levels in people from the Kaliningrad region with different body mass index (BMI). The material for the study was venous blood taken in the morning on an empty stomach from 232 people (mean age 50±13.5 years, 103 men and 129 women). The vitamin D content in the blood was determined by ELISA and the polymorphisms of the VDR gene were analyzed by PCR.
In individuals with a BMI 30 kg/m2, changes in the lipid profile and liver function tests were recorded. The vitamin D level did not depend on the BMI of the study participants. Significant changes in blood vitamin D levels were found depending on the distribution of the VDR genotype. Vitamin D levels were higher in individuals with the CC genotype than in the TT and CT genotypes of the rs2228570 polymorphism and did not depend on BMI. In contrast, the presence of the rs731236 polymorphism in the VDR gene is associated with BMI. In obesity, vitamin D levels are therefore only reduced in people with the TT genotype of the rs731236 polymorphism, but not in people with the CC and TC genotype.

The basis of the pathogenesis of immunologic male infertility is the production of antisperm antibodies against sperm antigens by plasmocytes. Extracellular nucleic acids, among other antigens, are perceived as DAMPs. The clearance system for biological fluids is complex. Endonucleases are responsible for the utilization of extracellular DNA. Among endonucleases, DNase 1 is the most studied. Its concentration in biological fluids is higher than others. For the first time, we determined the concentration of DNase 1 in the seminal fluid of men of reproductive age. DNase 1 concentration values were compared with the level of antisperm antibodies in the ejaculate, after which the relationship between the enzyme level and standard spermogram parameters was determined. The material for the study was the ejaculate of 44 relatively healthy men of reproductive age. During spermiological analysis, macroscopic and microscopic parameters of seminal fluid were determined, the concentration of deoxyribonuclease 1 (DNase 1) in the material was determined by enzyme immunoassay, and the presence of antisperm antibodies was assessed using a direct diagnostic method – the MAR test. Statistical processing of the obtained data was carried out using analytical software PAST v. 4.06. Reference intervals for DNase 1 concentrations were calculated using the MedCalc v. 17.4 program. The relationship between spermogram parameters and DNase 1 concentration was assessed by calculating Spearman’s linear rank correlation coefficients. As a result, a negative correlation was found between the DNase 1 ratio and such ejaculate parameters as liquefaction time (rS = -0.37; p = 0.013) and viscosity (rS = -0.37; p = 0.013), as well as the level of antisperm antibodies A (rS = -0.43; p = 0.003) and G (rS = -0.33; p = 0.027), the mucous component of the ejaculate (rS = -0.37; p = 0.012) and agglutination of male germ cells (rS = -0.33; p = 0.029). According to the data obtained, the optimal level of DNase 1 is directly related to the quality of the ejaculate. Determination of DNase 1 concentration can serve as an additional diagnostic criterion for male immunological infertility. These data will expand our understanding of a man’s fertile potential.
Immuno-RCA for highly sensitive detection of the antigen-antibody complex in the blood group antigen model

Published: October 2024

The problem of detecting tiny quantities of analytes by immunochemical methods has been tried for a long time. One approach is to use nucleic acid amplification methods to amplify the signal from a single antigen-antibody interaction. An amplification method suitable for microarrays is the rolling circle amplification reaction. The principle of the method is usage of a conjugate of a detecting antibody with a primer and subsequent isothermal amplification. The generation of a huge single-stranded reaction product starts after adding the necessary components for amplification reaction: circular oligonucleotides, which serves as a template for amplification and phage phi29 polymerase with the other components. This reaction product consists of a lot of repeats of a nucleotide sequence, that is complementary to the circular template. The fluorescent DNA probe can hybridize to each repeat on the product molecule, resulting in a significantly higher level of fluorescence than with fluorescently labeled antibody or streptavidin development systems. In addition, the reaction product remains immobilized on the surface, allowing usage of this approach for the detection of antigen-antibody interactions in other solid-phase analysis systems, such as microarrays. A common problem with such approaches is the nonspecific sorption of components of the immunochemical reaction or amplification reaction, leading to a high background. It is obvious that no matter how highly sensitive the analysis is in theory, a high background will reduce the entire potential of the method to nothing. Herein, we have developed a method that makes it possible to detect small amounts of antibodies to glycans in blood serum and in swabs from tumor cells in a microarray format using a model of blood group antigens. It was possible to obtain a 30 to 70-fold increase of fluorescence level from a specific interaction compared to the use of fluorescently labeled streptavidin. The method we are developing is promising, as it allows us to significantly increase the signal from the specific antigen/antibody interaction in the glycochip format, which will make it possible to detect antibodies to glycans in samples with a very low concentrations of antibodies, for example, in washes from tumor cells.

Published: October 2024

Studies were conducted to study the levels of pro- (IL-6, IL-18, IL-17A) and anti-inflammatory (IL-4) cytokines in the blood serum of pregnant women at different stages of gestation: 18-20, 28-30, and 33- 38 weeks. The study involved 76 patients at risk of developing preeclampsia. Of these, 34 women developed preeclampsia, making up the main group, and 42 pregnant women had no symptoms of preeclampsia and made up the comparison group. The control group consisted of 28 somatically healthy women with a physiologically normal pregnancy. The average age of the examined patients with preeclampsia was 26.2±4.3 years, and in the group of pregnant women with normal pregnancy it was 25.8±4.7 years. The purpose of the study was to study the levels of cytokines IL-4, IL-6, IL-17A, and IL-18 in women with uncomplicated pregnancy and preeclampsia. These cytokines play an important role in the immune response and may be associated with the development of preeclampsia. The results of the study may help further understand the mechanisms of the disease and develop strategies for its prevention and management.
The levels of pro- (IL-6, IL-18, IL-17A) and anti-inflammatory cytokines (IL-4, IL-10) were studied in blood serum by ELISA using test systems of Vector-best JSC (Novosibirsk, Russia) in accordance with the manufacturer’s recommendations. Statistical processing of research results was carried out using variation statistics methods. The results are presented as the sample mean (M) and standard error (m). The significance of the differences in the mean values (P) of the compared indicators was assessed using the Student t test (t). A study conducted by the authors found the following patterns in interleukin (IL) levels in pregnant women at risk of developing preeclampsia (PE). The levels of IL-6, IL-17A, and IL-18 were significantly increased in pregnant women with PE. There was a tendency to decrease the levels of IL-4, and IL-10 in women at risk of developing preeclampsia. These findings may help guide further research and development of strategies to prevent and manage preeclampsia in pregnant women.
Arrest Matters: The Pragmatics of Vulnerability in Phone Calls to the Stasi
Authors: Galanova Olga
Published: October 2024

Using Conversation Analysis (CA), this article focuses on the ways in which participants invoke vulnerability in phone calls to the former East German State Security Service, better known as the Stasi. The calls were made in the late 1970s and the 1980s and pertained in one way or the other to political arrests. The main aim is to understand the linkage between vulnerability as an attribute of an institutional setting and vulnerability as the mutual achievement of a social interaction with an organization. The data represent different ways of addressing experiences of vulnerabilisation and different complications, each with a specific interactional character (failed request for help, self-protection or expression of indignation about one’s own treatment). Starting with an ambiguous case and focusing on how participants work to describe experiences of arrest in other cases documented and available in the Stasi tape archive, the article describes the sequential unfolding of vulnerability in different formats, depending on how the recipient designs them and the communicative tasks that participants tackle in their interactions.

In a society where, sedentary lifestyles and the use of technological screens are on the rise, students' lifestyle is being significantly affected. In fact, nowadays many students experience various sleep problems, and two of its main factors may be physical activity and the use of technological screens. In this sense, this research aimed to analyze the influence of students' physical activity and the screen time on sleep quality of students. The participants were 28 students in 5th and 6th grade of primary school. They wore ActiGraph WGT3X-BT accelerometers for one week to collect data related to physical activity and sleep patterns. Additionally, a survey was conducted to assess their use of technological screens. The collected data were analyzed, with a focus on differences by sex. Correlations between these parameters were also analyzed. The analysis revealed no significant correlation between physical activity and sleep quality. However, a significant correlation was observed between screen time and sleep quality. This finding highlights the importance of continued research in these areas to enhance the wellbeing and sleep quality of students.

Nowadays, there are affordable and reliable sensor technologies to meet these needs. Purpose: The research aimed to design a test instrument that utilizes sensor technology to measure kick momentum in the sparring category of Pencak Silat following the applicable SI, and to test its reliability and validity. The resulting instrument is named Inosen’s Silat Momentum Test. Approach: This study followed Johnson and Nelson’s seven-test construction process. Twenty-four Pencak Silat athletes, consisting of 12 elite and 12 non-elite participants, were involved in the evaluation process. The test’s reliability was assessed by examining the correlation between the test and retest results. The construct validity test was conducted by comparing the results of the front kick tests of elite and non-elite Pencak Silat athletes. Data analysis was performed using Pearson correlation and independent t-tests using Minitab 21.4.1 software. Results: The results of the test and retest indicate a very high correlation (r = 0.923), demonstrating the consistent ability of Inosen’s Silat Momentum Test to measure kick momentum. The study found a statistically significant difference in the Inosen’s Silat Momentum Test scores (p < 0.05) between the elite fighter group (average score of 463.3 kg.m/s) and the non-elite fighter group (average score of 375 kg.m/s). The results indicate that Inosen’s Silat Momentum Test is an effective instrument for differentiating kick momentum based on fighter performance. Conclusions: Based on the findings, it is inferred that Inosen’s Silat Momentum Test is a reliable and valid instrument for measuring Pencak Silat kick momentum according to SI standards.

This study investigates the effects of addition of binding wires on the compressive strength of concrete. Different quantities of binding wires are added to the concrete to find out the optimum quantities of binding wires in which the FRC with binding wires is more effective in terms of strength and crack resistance capacity. Steel fibre reinforcement concrete (SFRC) is a composite material made of hydraulic cements, water, fine and coarse aggregate and dispersion of discontinues small fibre (steel fibre). It is one of the superior crack resisting building materials due to its ability to modify micro and macro cracking by intercepting cracks at their origin and inhibit crack growth. The study found that addition of steel fibre increased compressive strength at 7, 14, 28 days test. SFRC is a superior crack resisting building material due to its ability to modify micro and macro cracking by intercepting cracks at their origin and inhibit crack growth. The results of the study show that the addition of binding wires as fibre can significantly increase the compressive along with the crack arresting capacity. The results also give a detail idea of optimum quantity of steel fibre that can be used in concrete production to get better strength and at the same time it will be more economical.

One of the important areas of study in medical image processing is early disease detection and diagnosis. A subfield of medical image processing includes the brain tumour segmentation procedure. Medical professionals have an efficient means of diagnosing illnesses because to computer vision and machine learning technology. The Srgb based density analysis is used in this study to isolate the area of brain tumours in MRI images. To differentiate the tumour area from the surrounding area, the intensity values of the input are normalised using the Gaussian filter and the Srgb colour space. In brain MRI samples, the adaptive threshold approach aids in locating potential tumour space. By calculating region parameters like area and density function, the actual space occupied by brain tumours is recovered. Ultimately, by applying morphological functions and removing potential false positives, the accurate tumour space is identified. Recall, accuracy, and F-measure are a few of the performance indicators that are used to evaluate how effective the suggested strategy.

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease with an important course due to systemic compromise. SLE is frequently associated with antiphospholipid syndrome, and pulmonary thromboembolism (PE) is particularly common. It is extremely rare for PE to be the initial clinical presentation and even more uncommon for it to coincide with cardiac tamponade, representing a challenge in diagnosis and management. We present a case of a 42-year-old woman with recurrent PE with severe pleural and pericardial effusion, hemodynamic instability, and cardiac tamponade. Laboratory workup revealed hypocomplementemia, leukopenia, negative SLE antibodies, and a positive lupus anticoagulant. This case emphasizes the importance of determining the etiology of PE, assessing risk classification, and implementing proper management, which are crucial for the patient's survival and outcome.

Role of Ionic Strength in Solubility of Salts in India
Authors: Narmudi Adu
Published: October 2024

Purpose: The aim of the study was to assess the role of ionic strength in solubility of salts in India.
Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries.
Findings: Ionic strength increases, the electrostatic interactions between oppositely charged ions in the salt and the surrounding ions in the solution are weakened, leading to changes in solubility. Higher ionic strength often results in greater solubility of salts due to the shielding effect, which reduces ion pairing and prevents precipitation. However, in some cases, extremely high ionic strength may lead to the "salting out" effect, where solubility decreases as ions compete for solvation. This relationship is essential in fields like chemistry and environmental science, where understanding solubility is crucial for processes such as crystallization and precipitation reactions.
Implications to Theory, Practice and Policy: Debye-hückel theory, van’t hoff factor and colligative properties theory may be used to anchor future studies on the role of ionic strength in solubility of salts in India. Industries involved in chemical manufacturing and wastewater treatment should adopt protocols that account for ionic strength when designing their processes. Policymakers should establish regulatory frameworks that promote the inclusion of ionic strength considerations in environmental assessments.
