Abscopal Effect Demonstrated on [18F]FDG PET/CT in a Case of Renal Cell Carcinoma Postnephrectomy
Authors: Sagar Sambit , Khan Dikhra , Kundu Nivedita , Shamim Shamim Ahmed , Kumar Rakesh
Published: November 2024

Renal cell carcinoma accounts for 3% of all malignancies with many of them presenting with metastasis at the time of presentation. The abscopal effect, a phenomenon characterized by systemic bystander effects on nontargeted lesions due to local therapy, has been extensively studied in the context of radiotherapy and immunotherapy. However, documentation of the abscopal effect following surgery remains limited. We present a case of a 67-year-old Indian male diagnosed with clear cell renal cell carcinoma (RCC), who underwent left radical nephrectomy. Baseline staging and postnephrectomy follow-up scans with fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET-CT) revealed an FDG-avid primary lesion in the left kidney with metastasis to the left lung. Surprisingly, the follow-up FDG PET-CT scan demonstrated the resolution of the left lung metastasis, indicating the occurrence of the abscopal effect resulting from the local nephrectomy. This rare clinical observation highlights the potential of surgery to induce immunogenic tumor neoantigens release and inflammatory factors, leading to systemic antitumor effects. While the abscopal effect has been extensively studied in the context of radiotherapy and immunotherapy, there is a scarcity of studies reporting nephrectomy promoting such systemic effects. The combination of radiotherapy and immunotherapy has shown promising results in enhancing tumor immunosuppression and facilitating the abscopal effect. We report a case of RCC with lung metastasis showing abscopal effect with resolution of lung nodule postnephrectomy on 18-F-FDG PET-CT.

Authors: Tayal Sachin , Jain Yash , Thakur Sonali , Shukla Varun , Venkatachalam Manikandan Marappagounder , Kumar Ajay , Sinha Ritwik
Published: November 2024

Background:

The introduction of positron emission tomography/computed tomography (PET/CT) has significantly advanced medical imaging. In oncology, 18F-fluorodeoxyglucose (18F-FDG) PET/CT is particularly crucial for staging, evaluating treatment response, monitoring follow-up, and planning radiotherapy. However, in resource limiting hospitals, the availability of fluorine-labeled 18F-FDG limits optimal scan acquisition. This study aims to determine the optimal dosage and acquisition time to maximize patient throughput during shortages.

Aim and Objective:

To optimize low-dose 18F-FDG scan protocols while maintaining high image quality despite radiotracer availability challenges.

Materials and Methods:

PET/CT scans were performed using GE’s Discovery IQ 5-ring, 16-slice system within 40–60 minutes of intravenous 18F-FDG injection. The protocol was adjusted to a low-dose (0.05 mCi/kg of 18F-FDG), and the PET data acquisition time was increased to 3 min per bed position to ensure image quality.

Results:

Notable differences were observed in image quality scores based on varying acquisition times, with the extended acquisition time helping maintain diagnostic standards despite reduced tracer doses.

Conclusion:

The high sensitivity and long axial length of the PET/CT system (with five rings spanning 26 cm AFOV) can significantly alleviate the challenges faced by cyclotron-dependent centers. By leveraging the increased sensitivity, we successfully reduced the injected activity rather than the scan time to address the tracer shortage at our institute. This approach proved to be effective in maintaining image quality and patient care standards.

Authors: Mathur Tanuj , Vishwapriyanka G. , Kumar Bipin , Chaitanya Perugu Damodara Krishna
Published: November 2024

Background:

Breast cancer is one of the most common cancers affecting women globally, with risk factors including genetic predisposition, environmental influences, and hormonal exposure. The use of in vitro fertilization (IVF) has been associated with high doses of hormonal treatments, raising concerns about the potential increase in breast cancer risk due to these treatments. This study aims to evaluate the incidence of breast carcinoma following recurrent IVF treatments.

Methodology:

This retrospective cohort study involved 62 women who underwent three or more IVF cycles at a single fertility clinic. Participants were selected based on their comprehensive medical records from the clinic’s database, excluding those with known genetic predispositions to breast cancer. The study cohort was compared with a control group of 62 women who did not undergo IVF but were matched for age and socioeconomic status. Breast cancer incidence was identified through cross-referencing participant records with national cancer registries.

Results:

Of the 62 women in the IVF group, 8 (12.9%) developed breast carcinoma compared to 4 (6.5%) in the control group. The median time from the first IVF treatment to the cancer diagnosis was 7 years. Statistical analysis using Cox proportional hazards models revealed a hazard ratio of 2.1 for developing breast carcinoma among IVF participants compared to controls, although this was not statistically significant (95% confidence interval: 0.8–5.4; P = 0.12).

Conclusion:

The findings suggest a higher incidence of breast carcinoma in women undergoing recurrent IVF treatments compared to those who did not undergo such treatments, although the results did not reach statistical significance. The study highlights the need for further research with larger cohorts to robustly determine the relationship between IVF treatments and breast cancer risk. Enhanced screening and monitoring for breast cancer may be advisable for women undergoing repeated IVF cycles.

Authors: Kedia Sameer , Wasu Prashant , Wankhade Shruti , Wasu Shilpa , Patil Punam , Dehenkar Manisha
Published: November 2024

Background:

Oral squamous cell carcinoma (OSCC) is a prevalent and aggressive form of cancer with a high-mortality rate. Early detection and prognosis are critical for improving patient outcomes. Salivary biomarkers have emerged as noninvasive and promising tools for the early detection and monitoring of OSCC. This study aims to evaluate the role of specific salivary biomarkers in the early detection and prognosis of OSCC.

Materials and Methods:

A total of 100 participants were recruited for this study, including 50 patients diagnosed with OSCC and 50 healthy controls. Saliva samples were collected from all the participants and analyzed for the presence and concentration of specific biomarkers, including cytokines, DNA methylation patterns, and microRNAs. Enzyme-linked immunosorbent assay, polymerase chain reaction, and next-generation sequencing were employed to quantify and identify the biomarkers.

Results:

The study found that the levels of specific salivary biomarkers, such as interleukin-6 (IL-6), microRNA-21 (miRNA-21), and hypermethylation of the p16 gene, were significantly elevated in OSCC patients compared to healthy controls. The mean concentration of IL-6 in OSCC patients was 45.3 pg/mL, whereas in healthy controls, it was 12.7 pg/mL. Similarly, miR-21 levels were 3.5-fold higher and p16 hypermethylation was observed in 70% of OSCC patients compared to 10% in the control group. The sensitivity and specificity of these biomarkers for OSCC detection were 85% and 90%, respectively.

Conclusion:

Salivary biomarkers such as IL-6, miR-21, and p16 hypermethylation demonstrate significant potential in the early detection and prognosis of OSCC. These noninvasive biomarkers can aid in the timely diagnosis and management of OSCC, improving patient outcomes and survival rates. Further large-scale studies are warranted to validate these findings and integrate salivary biomarker testing into routine clinical practice.

Authors: Bhattacharjee Samiksha , Bhattacharya Sudip
Published: November 2024

The use of fixed dose combinations (FDCs) in healthcare has significant public health implications, both positive and negative. Positive aspects include simplifying treatment regimens, improving patient adherence, and cost-effectiveness, particularly in resource-constrained settings. However, negative implications arise when FDCs are used without careful consideration, leading to irrational combinations, reduced treatment options, and potential overuse. Moreover, substandard FDCs and aggressive marketing can pose risks, such as antibiotic resistance and treatment failures. Mitigating the negative implications of FDCs requires a comprehensive strategy. Strengthening regulatory oversight, rigorous approval processes, and clear scientific evidence for FDCs’ benefits over single-drug formulations are essential. Transparency in the approval process, regular reviews, and postmarketing surveillance hold regulatory agencies accountable. Training and education for healthcare professionals, emphasizing evidence-based decision-making, and encouraging adverse event reporting can help ensure rational use. Pharmacovigilance programs, clinical practice guidelines, and national formularies aid in monitoring and guiding FDC use. Public awareness campaigns and patient engagement foster informed discussions and reporting. Research and development efforts should focus on optimizing FDC formulations and assessing cost-effectiveness. International collaboration to harmonize standards and prevent substandard FDCs’ global spread is crucial. Legal measures should be in place to deter misleading marketing and distribution of unsafe FDCs by pharmaceutical companies. In conclusion, addressing the negative implications of FDCs involves a multifaceted approach that spans healthcare professionals, regulators, pharmaceutical companies, and the public. By ensuring rational and safe use, FDCs can maximize their benefits while minimizing associated risks in the realm of public health.

Authors: Tolani Priyal H. , Phatak Mrunal Suresh
Published: November 2024

Context:

Music has been used for healing purposes since ancient times. Music therapy is a growing branch which can facilitate and promote a healthy mind and body. Autonomic nervous system (ANS) may serve as one path by which music exerts its therapeutic effects. Interaction between the ANS and cardiovascular system during exercise can be of prognostic importance in many cardiovascular diseases. The measurement of the effects of musical auditory stimulation, using non-invasive test of heart rate variability (HRV), on cardiac auditory response while under stressful condition, like exercise, would help understand the usability of musical interventions in prevention and treatment of cardiovascular diseases.

Aim:

To gauge the effects of preferential relaxing music on exercise-induced changes in frequency domain parameters (LF, low frequency; HF, high frequency; LF: HF ratio) of HRV.

Setting and Design:

Experimental study design.

Methods and Materials:

Sample size—52 healthy young adult volunteers (18–25 years). HRV was measured from the ECG obtained at rest, while listening to preferential relaxing music, after doing moderate exercise and after doing moderate exercise while listening to preferential relaxing music.

Statistical Analysis Used:

Comparison of frequency domain HRV variables was done using paired t-test.

Results:

Non-significant increase in HF component (P value = 0.3) and non-significant decrease in LF: HF ratio (P value = 0.06) after doing moderate exercise with music when compared with after doing moderate exercise without music was observed.

Conclusion:

Preferential relaxing music attenuated exercise-induced decrease in parasympathetic activity post-exercise.
Vietnamese Migrants in Modern Russia: Resettlement, Institutions and Social Boundaries
Authors: Avdashkin Andrey A.
Published: November 2024

In the post-Soviet period, migrants from Asian countries were unevenly distributed across Russian regions, which influenced the emergence of ethnic markets in the 1990s. In order to advance the field of migration and border studies, it is important to understand why communities of Vietnamese rather than Chinese or Central Asian migrants have formed in some cities. The presence of migrants suggested designating certain places with ethnic terms, etc. The paper is intended to answer the following questions: what is the geography of the settlement of migrants from Vietnam, in what cities and why exactly were Vietnamese markets formed and what migration institutions arose thanks to them. The archival documents from the post-Soviet era, and the results of the Autor’s field work in Magnitogorsk, Orenburg and Ufa made the source base for the research. The materials collected in Moscow, Chelyabinsk and Yekaterinburg provided great assistance. The methodological basis of the manuscript is the theory of mobility. Vietnamese communities were formed by migrants who did not leave Russian cities after 1991. The Vietnamese in these cities were engaged in commercial entrepreneurship, established Vietnamese markets and social infrastructure, invited compatriots through these institutions, and provided various kinds of support to “their own” people. However, the economic instability in Russia led to the immobility of the Vietnamese, both intentionally or involuntarily, which had a profound impact on the geography of the Vietnamese settlement in Russia and the ways of organizing social ties.
Eugenio Trías: el filósofo, el intelectual y el poder
Authors: IBÁÑEZ FANÉS Jordi
Published: November 2024

La relación más clara y directa de Eugenio Trías con la política fue su actividad como comentarista de la política catalana, española e internacional en los diarios El País, El Mundo y ABC sucesivamente. En este artículo nos proponemos reflexionar sobre su producción en este ámbito entre los años 1994-2004, teniendo en cuenta la intensidad política de esta década no sólo en España (el fin de los años de González, las dos legislaturas de Aznar y el regreso socialista al poder), sino también en el mundo (ataques de septiembre de 2001 en Estados Unidos, invasión de Irak en marzo de 2003, atentados en Madrid en marzo de 2004).  Trías nos ofrece un estudio de caso singular y a la vez representativo de las relaciones entre los medios (prensa en papel), la política, la intelectualidad y el poder en España. Su periodismo y posiciones políticas poco o nada tienen que ver con su filosofía, sino es para trivializarla. Pero es interesante de ver cómo el filósofo se resiste a ser tomado por un intelectual, ocultando esta condición bajo la figura del profeta e incluso del partisano.

Lo universal a raíz de la sexta Meditación sobre el poder
Authors: ESTÈVE Raphaël
Published: November 2024

Movilizamos en el presente trabajo la noción políticamente operativa de universalidad a raíz du una curiosidad sintagmática enunciada en la sexta meditación de Meditación sobre el poder (1976): "el universal malentendido", reversible en un "universal entendido mal". Lo que al mismo tiempo problematiza epistemológicamente y presupone ontológicamente la existencia factible de esa universalidad. Ese sintagma constituirá así para nosotros a la vez un núcleo generador y un punto de referencia para explorar el devenir, en la obra ulterior de Trías de la dimensión política del concepto de universal tal y como la plantea en términos que postulamos seminales para el autor esta sexta meditación. Las organizaremos en cuatro líneas de rastreo privilegiando, acorde con la temática del presente dossier, su dimensión también ética: la ideología, la esencia, el absolutismo, y la enunciación.

Innovative Strategy for Rainwater Harvesting in Saline-affected Urban Areas: A Case Study of a Sports Complex in Delhi
Authors: Hamid Yasir , Mehmood Gauhar
Published: November 2024

Water scarcity remains a critical global challenge, requiring immediate, sustainable management strategies, particularly in areas with an increasing disparity between water supply and demand. In India, and especially in Delhi, this issue is acute. In response to growing environmental concerns and the urgent need for sustainable water resource management, rainwater harvesting has emerged as a practical and effective solution for water conservation. This study investigates the application of rainwater harvesting to sustainably support water needs for a sports complex located in a salinity affected region. The land, originally intended for agriculture, has been converted into a complex featuring hydro-landscape facilities, including swimming pools, water polo areas, diving pools, toddler pools, and leisure pools. These facilities require an initial water input of 6,754.5 m³ and an annual replenishment of 7,957.28 m³ due to evaporation and seepage. By calculating the total rainwater harvesting potential based on the runoff coefficient, annual rainfall intensity, and the complex's catchment area, the study reveals that 29,693.8 m³ of rainwater can be harvested annually, providing a surplus of 14,981.7 m³ of potable water. This analysis demonstrates the viability of designing sports complexes in saline areas using efficient land use and rainwater harvesting, and presenting a scalable model for sustainable water management in similar regions worldwide.

This paper examines the distribution of potentially toxic elements (PTEs) among various soil particle sizes, with a focus on Fluvisol soils in Novi Sad, Serbia, which are distinguished for their high sand content. Potentially toxic elements (PTEs), as As, Co, Cr, Cu, Mn, Ni, and Pb were analyzed in urban soil in the vicinity of major roads and distribution factors (DF) were calculated. Urban soil was initially collected as bulk samples and then separated into seven distinct particle size fractions through wet sieving. Based on the obtained results, the highest values were observed in the finest fraction (< 25 μm), followed by larger fractions (500-1000 μm), while the lowest values were found in the medium-sized particles (125-250 μm). Considering the predominant presence of sand as larger particle in urban soils worldwide, it is important to include coarser fractions in the risk assessment for the urban environment.

Authors: Tang Wei , Zhang Di , Wang Qiwen
Published: November 2024

This study aims to make visible and investigate changes in the patterns of trade in fisheries and aquaculture products, which are heavily traded and of high importance for food security in many Regional Comprehensive Economic Partnership (RCEP) member countries. The study uses fisheries and aquaculture products trade data from 2002 to 2022 and applies a complex network analysis to unveil the trade network of fisheries and aquaculture products within the RCEP region. It analyzes the topological structure and spatiotemporal evolution characteristics of the trade network, and utilizes QAP model to further examine the main factors influencing the characteristics of the fisheries and aquaculture products trade network. The study finds: (1) The density of the fisheries and aquaculture products trade network in the RCEP region has significantly increased, exhibiting “small-world” characteristics. With the increasing degree of trade integration, there is still much room for improvement in the cooperation and development of fisheries and aquaculture products trade; (2) The network displays a pronounced core-periphery structure, with China and Japan consistently occupying a central position in the RCEP region’s fisheries and aquaculture products trade network; (3) Economic size, comparative advantage, foreign dependence degree, per capita arable land area, contiguity, and institutional quality are significant factors affecting the relationships and trade volume among countries in the fisheries and aquaculture products trade network.
Family Quality of Life and Psychological Health Factors among Parents with Intellectually Disable Children; The Influence of Parenting Self-efficacy
Authors: Naz Sumaira , Noor Farukh
Published: November 2024

Parents have to face obstacles in handling the challenging behaviors linked to the children with intellectual  disability (ID) while a lack of understanding regarding ID limits their capacity to deliver ongoing care and assistance for these children's physical, emotional, psychological, and social growth. This insufficient knowledge of parents among ID children also influence their own pyschological health negatively which ultimately leads them towards low family quality of life. This situation is being worsened day by day in the world generally and in Pakistan particularly wherein overall 371,834 children bear different types of disabilities including intellectual disability (31,915) while majority of researches in Pakistan focuses on other disorders and a few researches are done on intellectual disability. Thus, this study was designed to determine the family quality of life and psychological health factors among parents with intellectually disabled children as well as the influence of parenting self-efficacy. For this purpose, primary data of 306 parents of intellectually disabled children (7-18 years old) was collected from 4 special education schools and one children’s hospital, Multan and Bahawalpur (Southern-Punjab) Pakistan. The collected data was analyzed in SmartPLS through PLS (SEM) technique. PLS (SEM) results show that psychological distress has large, negative and significant impact on family quality of life and parenting self-efficacy while parenting self–efficacy has large, positive and significant impact on family quality of life. Additionally, parenting self-efficacy significantly fully mediate the relationship between psychological distress and family quality of life. Findings of this study emphasize to draw the attention of parents, teachers, special education departments, policy makers and healthcare providers towards social, psychological, physical, educational and financial issues among the parents of intellectually disabled children for taking immediate supporting measures.

O tratamento hormonal consistiu em, no D0, inserção do dispositivo intravaginal de progesterona (P4) e aplicação de benzoato de estradiol (BE) e, no D11, a realização da IATF. Os dois primeiros protocolos (PROT1 e PROT2) foram realizados em quatro manejos, com aplicação de gonadotrofina coriônica equina (eCG) no D7 e prostaglandina (PGF2a) no D9. O PROT3 em três manejos, com aplicação de PGF2a, eCG e cipionato de estradiol (ECP) no D9. Independentemente do protocolo, todas as fêmeas foram inseminadas no D11. Após 30 dias da IATF, realizou-se diagnóstico de gestação (DG), com auxílio de ultrassom. Para análise estatística, utilizou-se o software Statistical Package for Social Science (SPSS), versão 27.0, a 5% de significância. Do total de fêmeas, denotou-se associação significativa (p = 0,05) entre o DG e as variáveis ordem de parto, protocolo, ressincronização e manifestação de estro. Em seguida, quando estratificado por ordem de parto, foi observada associação significativa (p = 0,05) entre o DG e as variáveis protocolo, ressincronização e manifestação de estro para pluríparas, primíparas e nulíparas. Além de ter havido efeito (p = 0,05) para o escore de condição corporal (ECC) no D11 e no DG, entre as distintas parturientes. Ademais, considerando os protocolos, verificou-se associação significativa (p = 0,05) entre o DG e as variáveis ordem de parto e manifestação de estro para PROT1, PROT2 e PROT3. Conclui-se que fêmeas bovinas com aptidão para corte, de distintas ordens de parto, apresentam desempenho reprodutivo satisfatório ao serem submetidas a protocolos de quatro manejos, principalmente com o uso da dupla aplicação de eCG em pluríparas e primíparas em anestro. Por fim, a identificação da intensidade dos sinais de estro destaca-se como um fator importante para a otimização dosresultados finais da IATF.

Published: November 2024

В статье проводится исследование денежных потоков как фактор обеспечения финансовой стабильности организации. Рассмотрены подходы ученых экономистов по проблематике денежных потоков и доходов, которые позволяют сделать вывод о недостаточной проработанности данной темы для субъектов хозяйствования. Денежные средства являются крайне важным ресурсом. Необходимо обеспечивать равномерность и сбалансированность денежных потоков во избежание возникновения ситуации дефицита денежных средств.

The article examines cash flows as a factor in ensuring the financial stability of an organization. The approaches of academic economists on the problems of cash flows and income are considered, which allow us to conclude that this topic is insufficiently elaborated for business entities. Cash is an extremely important resource. It is necessary to ensure the uniformity and balance of cash flows in order to avoid a situation of cash shortage.
