Authors: Osama Md Ali , Chatterjee Priti , Singh Smita , Pandey Ankita , Mohta Anup 
Published: July 2024

ABSTRACTLiposarcoma is a rare mesenchymal neoplasm commonly involving deep soft tissues and the retroperitoneum. Among the various types of liposarcoma, myxoid liposarcoma is the most frequently encountered in adolescents and young adults, with a predilection for lower extremities. Fine needle aspiration allows easy assessment and rapid on-site evaluation for distinguishing benign from malignant lipomatous lesions. Here, we present a case of myxoid liposarcoma in the calf region of a 19-year-old boy, diagnosed via fine needle aspiration cytology, and subsequently confirmed by histopathological examination after surgical resection. The intention behind this case report is to highlight the cytological features of myxoid liposarcoma and to improve understanding of this tumor entity, aiming to prevent misdiagnosis by inexperienced pathologists when evaluating cytology specimens.
Diagnostic Utility of High Fluorescence Cells in Detecting Malignant Effusions
Authors: Mishra Shashank , Parikh Biren P. , Singh Jayvardhan 
Published: July 2024

Background:
Most modern haematology analysers have a dedicated body fluid mode for cell counts of body fluids. Many analysers also count the number of high fluorescence cells (HF cells). HF cells have a large nuclear size and emit high fluorescence when stained with fluorescent dyes. Due to their large nuclear size, Malignant cells are counted as HF cells.

Aims and Objectives:
We aim to determine the diagnostic utility of HF cells in predicting the presence of malignant cells in serous effusions.

Materials and Methods:
HF cell counts were done on 209 serous fluid samples using the body fluid mode of Mindray BC-6800 plus haematology analyser. Papanicilaou-stained smears of all samples were examined for the presence of malignant cells by a panel of cytopathologists. ROC curve analysis was done to determine the sensitivity and specificity of HF cells in malignant effusions.

Results:
Out of 209 samples, malignant cells were found by microscopy in 97 cases (46.4%). The absolute number and percentage of HF cells were significantly higher (P < 0.001) in malignant effusions (HF# = 24.9 cells/ul, HF% = 10.4%) when compared to non-malignant samples (HF# = 4.95 cells/ul, HF% = 5.76%). ROC curve analysis determined an optimal cut-off of ≥30 HF cells/ul (sensitivity = 73.91, specificity = 55.66%) for the prediction of malignant cells.

Conclusion:
HF cells in serous effusions can be a helpful tool to aid the pathologist, but it is not an ideal screening test due to its low sensitivity (67.74%) and negative likelihood ratio (0.5) at a cut-off of ≥30 HF cells/ul. However, due to high specificity of 83.18% at a cut-off of ≥72 HF cells/ul, a meticulous search for malignant cells should be done on microscopy.

Authors: Boler Anup Kumar , Roy Shreosee , Singh Ph Priyanca , Maiti Barnali 
Published: July 2024

Background:
Touch imprint cytology (TIC) of core needle biopsy specimen is an easy method of rapid on-site evaluation (ROSE) which aids in the rapid diagnosis of breast lumps by cytological analysis.

Objective:
To evaluate the efficacy of touch imprint cytology in predicting the adequacy of needle core biopsy of breast lumps and its diagnostic accuracy for malignancy.

Materials and Methods:
This study was done in Burdwan Medical College over a period of two years on 80 patients who had presented with breast lumps and had given consent for core needle biopsy for diagnosis.

Results:
Out of 80 cases, satisfactory materials on touch imprint were obtained in 79 cases. Only one case did not yield satisfactory material and hence was excluded from the analysis. A total of 43 cases were malignant, and 36 cases were either benign or inflammatory on core needle biopsy. Thirty-seven cases were accurately diagnosed as malignant by TIC, and 35 cases were accurately diagnosed as benign by TIC. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of TIC were 86.05%, 97.22%, 97.37%, and 85.36%, respectively, and the overall accuracy was 90%.

Conclusion:
TIC of core needle biopsy is a rapid, reliable, and accurate method for early cytological diagnosis of symptomatic breast lesions. It can be used routinely at the site of biopsy to evaluate the adequacy of materials obtained during core needle biopsy and to plan for further workup in case of malignant breast lesions.
Fine-needle Aspiration Biopsy of Pilomatrixoma (Cytological Features of Six Cases Histologically Approved)
Authors: Ozcan Burcu , Erdogan-Durmus Senay 
Published: July 2024

Background and Objective:
Pilomatrixoma is a rare, benign, slow-growing tumor of the hair matrix. Excisional biopsy is often the preferred method of diagnosis for cutaneous masses including pilomatrixoma. However, fine-needle aspiration is also performed on these lesions. There are very few reports on the cytologic features of pilomatrixoma in fine-needle aspiration. In this study, we aimed to evaluate the clinical and cytological features of six cases of pilomatrixoma, which were confirmed histopathologically.

Materials and Methods:
The study includes six cases of pilomatrixoma, which were diagnosed by two cytopathologists in 2019 and 2022. A detailed cytological analysis was done by a semiquantitative method. Cellularity, basaloid cells, squamous cells, giant cells, shadow cells, naked nuclei, calcium deposits, inflammation, and debris were semiquantified from 0 to 3+.

Results:
The ages of patients ranged from 8 to 63 years old. The male-to-female ratio was 2:1. All cases occurred in the head and neck area. The cytological diagnosis was pilomatrixoma in five cases and epidermoid/dermoid cyst in one case. The surgical excision was performed in all patients. The diagnosis of pilomatrixoma was confirmed histologically in all cases.

Conclusıon:
Fine-needle aspiration biopsy (FNAB) of pilomatrixoma can be a diagnostic challenge. There are very few reports on the cytologic features of pilomatrixoma in FNAB smears. The presence of ghost cells and basaloid cells should suggest the possibility of pilomatrixoma. The presence of giant cells, fibrillary matrix, calcium deposits, squamous cells, naked nuclei, inflammation, and debris are cytological findings supporting the diagnosis.
The Power of Cultural Validation: A Global Strategy for Combating Infectious Diseases
Authors: Soto Julissa ,   CEO, Public Health Advocate, Health Equity Consultant, USA
Published: July 2024

Cultural Validation is a technique that works to increase access and break down barriers for what many policymakers and public health officials identify as “hard to reach populations.” During the COVID-19 Pandemic, policymakers and public health officials often cited “vaccine hesitancy” as a key challenge to reaching vulnerable populations, including immigrants, Spanish-speaking communities, and others who have been marginalized. Yet, community-based programs utilizing “Cultural Validation” techniques demonstrated that barriers to access – not hesitancy – were the true culprits. In fact, public health partnerships, laws, policies and funding that support the full integration of Cultural Validation techniques can ensure vaccine equity across the board. Cultural Validation can be applied to any community, and its success is made possible by four 4 key factors: •	Researching and getting to know people in the community through genuine and authentic relationship-building prior to engagements. •	Developing culturally relevant materials and marketing strategies. •	Hosting events at places that are familiar to the community. •	Providing genuine, authentic care in service delivery
The Implementation of Sustainable Development Goal 13 in “BRICS” Countries” a Scoping Review
Authors: Bangura Samuel 
Published: July 2024

The essence of the 2030 Agenda for Sustainable Development, ratified by all member states of the United Nations in 2015, is encapsulated in the 17 Sustainable Development Goals (SDGs). The present study examines the progress made in achieving UN Sustainable Development Goal (SDG) 13 within the context of Brazil, Russia, India, China, and South Africa (BRICS), employing a business and economic perspective. The research methodology employed encompassing a comprehensive review of pertinent literature as well as a meticulous analysis of relevant documentary content. Findings from the study revealed that though businesses in BRICS countries are trying to adopt the United Nations sustainable development goal 13, But there is limited effort in Brazil in the implementation of sustainable development goal 13. In Russia most companies are committed to the implementation of united nations sustainable development goal 13, but this has been constrained by sanction and the war in Ukraine. In addition, Indian companies are fulfilling their corporate social responsibilities viewed through the United Nations sustainable development goal 13. The effort on the part of Chinese companies and the government of China in implementing the United Nations sustainable development goal 13 is commendable as various corporate social responsibility programs and public education have been implemented. In the same vein South African companies have also been seen as very active in the implementation the United Nations sustainable development goal (SDG) 13 by having very important policies built around the goal. Recommendation state that it is imperative that climate change be duly addressed within the overarching vision and objectives of the BRICS businesses as well and there should be a multi-tiered collaboration among BRICS countries to expedite the realisation of the sustainable development goals 13. Equally important harmonisation between governmental bodies, non-governmental organisations, and conscientious corporate entities can be instrumental in attaining superior outcomes regarding the sustainable development goal (SDG) 13. Future studies should include and examine more companies and additional countries in terms of overall plans for achieving the United Nations Sustainable Development Goal 13.

The relevance of the study is related to the of nuclear control safety. Determining the temperature coefficient of reactivity (TCR) experimentally is a rather difficult problem. One of the main difficulties is to heat up the reactor from two (or more) heat sources with different temperatures for a long time, sufficient for the isothermal heating of all reactor parts. The proof of the reactor isothermal heating may be the equalization of the coolant temperature in the distribution header (at the reactor inlet) and in the drain header (at the reactor outlet) for a time sufficient to stabilize the reactor critical state and the position of the regulatory authorities accordingly.The essence of the study method is related to the fact that during the experiment to determine the TCR, the conditions were created under which barometric (hydrodynamic) and power effects affecting the research reactor reactivity were excluded.The significance of the results is the fact that the TCR, one of the important safety assessment parameters for the IVG.1M reactor, was determined experimentally after the reactor was converted from highly enriched (HEU) to low enriched uranium (LEU) fuel.
