Abstract
Cytological specimens play a pivotal role in head and neck nodule/mass work up and diagnoses. The specimens´ importance has grown with the onset of personalized medicine and the routine use of molecular markers in the diagnostic work up. The Updates in Head and Neck Cytopathology Short Course ran during the 35th European Congress of Pathology held in Dublin, Ireland, in 2023 and brought together experts in cytopathology, pathology, and related fields to share their expertise and experience in the field of head and neck cytopathology and its future directions. Topics such as a one-stop clinic, the Milan System for Reporting Salivary Gland Cytopathology, next generation sequencing, and human papilloma virus detection in the head and neck area were covered during the short course. These topics are briefly summarized in the present review.

Abstract
Urine cytopathology is a cost-effective method to diagnose and follow patients with high grade urothelial carcinoma (HGUC). However, some benign, reactive and metaplastic changes may mimic HGUC and pose a diagnostic challenge for cytopathologists. Summary: Our comprehensive review focuses on summarizing common pitfalls encountered in urine cytopathology, based largely on the experience of the senior author (AC) utilising the diagnostic criteria described in the 2nd edition of The Paris system (TPS) for reporting urinary tract cytopathology and in recent published literature. These include urothelial tissue fragments, instrumented samples, degenerative changes, treatment effects, viral cytopathic changes, iatrogenic and metaplastic changes. Our aim is to provide a clear understanding of these challenges to assist cytopathologists in making accurate diagnoses. Key Message: It's crucial for cytopathologists to recognize benign, reactive and metaplastic lesions that could resemble HGUC. Awareness of these cytological features is essential to minimise diagnostic errors.

Abstract
We present the measurement of the cosmic ray proton spectrum from 50 TeV to 1.3 PeV using 7.81×10^{6} extensive air shower events recorded by the ground-based GRAPES-3 experiment between 1 January 2014 and 26 October 2015 with a live time of 460 day. Our measurements provide an overlap with direct observations by satellite and balloon-based experiments. The electromagnetic and muon components in the shower were measured by a dense array of plastic scintillator detectors and a tracking muon telescope, respectively. The relative composition of the proton primary from the air shower data containing all primary particles was extracted using the multiplicity distribution of muons which is a sensitive observable for mass composition. The observed proton spectrum suggests a spectral hardening at ∼166 TeV and disfavors a single power law description of the spectrum up to the Knee energy (∼3 PeV).

Abstract
INTRODUCTION Despite the established role of the interventional pathologist, their diagnostic performance is difficult to establish. At least in Spain training of pathology residents in ultrasound-guided interventional procedures for specimen collection is limited or absent in most institutions. We present our teaching experience in the instruction of ultrasound-guided fine-needle aspiration (FNA) to pathology residents in a tertiary-level hospital. MATERIALS AND METHODS The training of pathology residents who rotated through the interventional unit of the pathology department and the application of ultrasound-guided FNA and rapid on-site evaluation (U-ROSE) was documented over 5 years. The training period was broken down into learning phases and included the number of ultrasound-guided FNA performed, anatomical location, and their diagnostic performance, among other aspects. RESULTS Nineteen (19) pathology residents were trained in U-ROSE, and performed a total of 4003 procedures, with a mean of 211 per resident. In 53% of cases only one pass was required for an adequated sample. The specimen was diagnostic in more than 97% of cases. The most frequently sampled anatomical sites were the thyroid gland (n = 2347), followed by lymph node (n = 667), soft tissues (n = 663) and salivary glands (n = 322). CONCLUSION The results support the training programme followed by pathology residents in learning U-ROSE, which is essential to lay the foundations for the future interventional pathologist.

Abstract
The International System for Reporting Serous Fluid Cytology (TIS) has been proposed by an expert working team composed of the International Academy of Cytology and the American Society of Cytopathology, following an international survey. Since its introduction, the TIS has gained worldwide acceptance, and this review aims to assess its global impact. A literature search revealed 25 studies which have presented data on the impact of the TIS. Most of them provide data, including risk of malignancy (ROM) for each diagnostic category, separately for pleural, peritoneal and pericardial effusions, while a few do not separate them. A few studies focus on specific diagnoses like mesothelioma on specific types of fluids or more specific issues like the optimal fluid volume for cytology or interobserver variability. A synopsis of the data from the literature search is presented in four tables. The ROM assessment is discussed, as well as interobserver variability and the use of ancillary diagnostic immunochemistry. In conclusion, our review of the published data suggests that the TIS is a valid classification scheme that has been widely accepted by pathologists globally, is highly reproducible and makes a valuable contribution to clinical therapeutic management.

Abstract
The current article presents a huge enhancement in the field emission characteristics of zinc oxide (ZnO) micro/nanorods by nickel doping. The synthesis of pure and nickel-doped zinc oxide (ZnO) micro/nanorods was done by a simple low-temperature chemical method. Both the as-prepared pure and doped samples were analyzed by X-ray diffraction and electron microscopy to confirm the proper phase formation and the developed microstructure. UV-vis transmittance spectra helped in determining the band gap of the samples. Fourier-Transform Infrared Spectroscopy (FTIR) spectra showed the different bonds present in the sample, whereas X-ray Photoelectron Spectroscopy (XPS) confirmed the presence of nickel in the doped sample. Photoluminescence (PL) spectra showed that after doping, the band-to-band transition was affected, whereas defect-induced transition had increased significantly. After the nickel doping, contact angle measurement revealed a significant decrease in the sample's surface energy, leading to a remarkably high water contact angle (within the superhydrophobic region). Simulation through ANSYS suggested that the doped sample has the potential to function as an efficient cold emitter, which was also verified experimentally. The cold emission characteristics of the doped sample showed a significant improvement, with the turn-on field (corresponding to J = 1 μA cm-2) reduced from 5.34 to 2.84 V μm-1. The enhancement factor for the doped sample reached 3426, approximately 1.5 times higher compared to pure ZnO. Efforts have been made to explain the results, given the favorable band bending as well as the increased number of effective emission sites.

Abstract
PURPOSE/OBJECTIVE(S) Thoracic radiation improves survival in many lung cancer patients. However, radiation-induced cardiotoxicity is a major source of morbidity and mortality in such patients. Global longitudinal strain (GLS), a novel echocardiography (ECHO) method of assessing left ventricular function, has been shown to predict long-term adverse cardiovascular risk in diverse patient populations. We hypothesized that receipt of thoracic radiation is associated with GLS changes in lung cancer patients. MATERIALS/METHODS We retrospectively identified patients with lung cancer treated at our institution between 2005-2020 who had ECHOs performed both before and after RT, and in whom GLS was extractable. ECHO Board-Certified cardio-oncologists measured GLS and left ventricular ejection fraction (LVEF) from these ECHOs. RESULTS A total of 40 patients met inclusion criteria. Median time to ECHO was 78 days prior and 172 days after RT. Two chamber (2C), 3C, 4C, and average GLS were significantly decreased after RT on paired t-test [mean difference (SD) 2.23 (3.29), 2.99 (2.78), 2.25 (3.63), 2.51 (2.66) respectively, all p < 0.001]. Thirteen patients (32.5%) had abnormal GLS (<18%) prior to RT. 5 of those 13 patients (38.5%) had abnormal LVEF (< 50%). 27/40 patients (67.5%) had an abnormal GLS or clinically significant (≥15%) drop in GLS after RT. This difference (32.5% patients pre-RT vs 67.5% post-RT) was statistically significant (p < 0.01). Among patients (n = 27) who had normal LVEF before RT, 1 patient (3.7%) developed abnormal LVEF (<50%) after RT. Backwards logistic regression showed significant interaction between heart volume receiving 5 Gray and change in GLS. CONCLUSION This cohort exhibited a significant decrease in 2C, 3C, 4C, and average GLS after RT. ∼1/3 of patients had abnormal GLS at baseline (suggesting a high-risk group for cardiac complications) and 67.5% of patients had clinically significant decrease in GLS after RT. Among the patients with normal GLS before RT, although 51.9% of patients demonstrated a clinically significant drop in GLS after RT, only 3.7% of patients developed abnormal LVEF, suggesting that this is a late occurrence. GLS changes may serve as a valuable tool for early identification of patients who are at high risk for future cardiac complications after receiving thoracic radiation.

Abstract
The International Academy of Cytology has joined with the International Agency for Research on Cancer to bring together a group of experts in lung cytopathology to develop a WHO Reporting System for Lung Cytopathology (WHO System). This System aims to improve and standardize the reporting of cytopathology, facilitate communication between cytopathologists and clinicians, and improve patient care. The WHO System describes 5 categories for reporting lung cytopathology: 'Insufficient/Inadequate/Nondiagnostic', 'Benign', 'Atypical', 'Suspicious for malignancy', and 'Malignant', each one with a clear descriptive term, a definition, a risk of malignancy, and a suggested management algorithm. The key diagnostic cytopathologic features of each of the lesions within each category have been established by consensus through an Expert Editorial Board, who are also the authors of this review and selected for each reporting system and chosen based on their expertise in the field and/or diversity of geographical representation. Many other co-authors from around the world also contributed. The assignment of writing and editing responsibilities used the same model as that used for the WHO Classification of Tumours (https://whobluebooks.iarc.fr/about/faq/). The WHO System provides the best practice application of ancillary testing, including immunocytochemistry and molecular pathology, and guides in sampling and processing techniques to optimize the handling and preparation of specimens. The WHO System was created by the authors to be applicable globally and is based on cytomorphology with possibilities for additional diagnostic management of the patient. The authors are aware that local medical and pathology resources would differ, especially in low- and middle-income countries. The WHO Tumour Classification for Thoracic Tumors, Fifth Edition, is directly accessible through the online WHO System.

Abstract
In January 2021, hospitals and payer-specific entities in the United States were mandated to comply with the new pricing transparency rules. These rules applied to all standard charges a hospital applied to services provided to and for a consumer. From a financial perspective, the issue of price transparency in health care has for several decades surfaced as a legitimate concern of consumers, health care providers and payers. The aim of this article is to historically examine where and how pricing in health care began and to illustrate financial issues leading up to the current transparency in pricing required by health care payers and providers. A comparative analysis of issues and challenges pertaining to the transparency in pharmaceutical product pricing between the United States and India is also provided in brief.

Abstract
OBJECTIVE An international panel in the field of body fluid cytology, supported by the International Academy of Cytology and the American Society of Cytopathology, conducted a survey to identify opinions and explore existing practice patterns regarding body fluid cytopathology. METHODS The study group, formed during the 2018 European Congress of Cytology in Madrid, generated a survey of 54 questions related to the practice and taxonomy of body fluid cytology. The survey was available online from 28 August 2018 until 10 December 2018. Participants were invited through the websites and listserves of the professional societies. RESULTS The survey collected 593 international participant responses. Questions pertained to practice patterns and diagnostic language. Information was collected regarding credentials, work setting, work volume (4-10,000 samples) and years in practice (0-60 years). The responses revealed variations in diagnostic practice and sample management. Direct smears and ThinPrep® preparations are the most popular methods, followed by Cytospin® and SurePath®. Most (70%) respondents perform ancillary studies on their material, with over 50% preferring a cell block preparation. Approximately 32% indicated that they are capable of performing genetic studies on the samples. Nearly 78% of participants would accept a two-stage cytology report, with a preliminary assessment followed by a final diagnosis that accounts for ancillary studies to generate a more precise cytological interpretation. Approximately one-third (36%) never report adequacy on body fluid samples. Most (78%) report a general category result (negative, atypical, suspicious, or positive) and 22% provide a detailed surgical pathology type report. Most (73.6%) participants believe that both Papanicolaou stains and a modified Giemsa stain (eg Diff Quik) should be standard preparations for all serous fluid cytology. CONCLUSIONS The results of the survey demonstrated strong support for the development of a unified system for reporting body fluid cytopathology among respondents.

Abstract
The International Academy of Cytology has joined with the International Agency for Research on Cancer (IARC) to bring together a group of experts in lung cytopathology to develop a WHO Reporting System for Lung Cytopathology (WHO System). This WHO System defines five categories for reporting lung cytopathology, that is, "Insufficient"/"Inadequate"/"Non-diagnostic," "Benign," "Atypical," "Suspicious for malignancy," and "Malignant," each with a clear descriptive term for the category, a definition, a risk of malignancy and a suggested management algorithm. The key diagnostic cytopathology features of each of the lesions within each category have been established by consensus and will be presented more fully in a subsequent IARC e-book and published hard cover book.The WHO System provides the best practice application of ancillary testing, including immunocytochemistry and molecular pathology, and provides a review to guide sampling and processing techniques to optimize the handling and preparation of the cytopathology sample emphasizing the cytomorphological differential diagnosis to aid low-resourced settings. The authors recognize that local medical and pathology resources will vary, particularly in low- and middle-income countries, and have developed the WHO System to make it applicable worldwide based on cytomorphology with options for further diagnostic management of the patient.The online WHO System provides a direct link to the WHO Tumour Classification for Thoracic Tumours 5th Edition. It will raise the profile and use of cytopathology by increasing awareness of its current role and its potential role in the era of personalized medicine based on molecular pathology utilizing "small biopsies." Ultimately, the System will improve patient care and outcomes.This System aims to improve and standardize the reporting of cytopathology, facilitate communication between cytopathologists and clinicians and improve patient care. The System is based on the current role of lung cytopathology and synthesizes the existing evidence while highlighting areas requiring further research and the future potential role of lung cytopathology.

Abstract
The dataset was generated from Scopus database for the study due to its compatibility with bibliometrix R package. The dataset shows that there is a gradual increase in publication of research articles on digital health and mobile health till 2016 before a sudden rise in number of publications from 2017 onwards. This paper contributes by providing a consolidation of fragmented literature in the research domain giving us information on significant sources, authors and documents. The analysis of conceptual structure reveals that the topics of study have evolved from mobile health to digital health, e-health, technology acceptance model, privacy, implementation and self-management.

Abstract
BACKGROUND Pediatric salivary gland fine-needle aspiration (FNA) is uncommon with a higher frequency of inflammatory lesions and a small proportion of malignancies. This international, multi-institutional cohort evaluated the application of the Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) and the risk of malignancy (ROM) for each diagnostic category. METHODS Pediatric (0- to 21-year-old) salivary gland FNA specimens from 22 international institutions of 7 countries, including the United States, England, Italy, Greece, Finland, Brazil, and France, were retrospectively assigned to an MSRSGC diagnostic category as follows: nondiagnostic, nonneoplastic, atypia of undetermined significance (AUS), benign neoplasm, salivary gland neoplasm of uncertain malignant potential (SUMP), suspicious for malignancy (SM), or malignant. Cytology-histology correlation was performed where available, and the ROM was calculated for each MSRSGC diagnostic category. RESULTS The cohort of 477 aspirates was reclassified according to the MSRSGC as follows: nondiagnostic, 10.3%; nonneoplastic, 34.6%; AUS, 5.2%; benign neoplasm, 27.5%; SUMP, 7.5%; SM, 2.5%; and malignant, 12.4%. Histopathologic follow-up was available for 237 cases (49.7%). The ROMs were as follows: nondiagnostic, 5.9%; nonneoplastic, 9.1%; AUS, 35.7%; benign neoplasm, 3.3%; SUMP, 31.8%; SM, 100%; and malignant, 100%. Mucoepidermoid carcinoma was the most common malignancy (18 of 237; 7.6%), and it was followed by acinic cell carcinoma (16 of 237; 6.8%). Pleomorphic adenoma was the most common benign neoplasm (95 of 237; 40.1%). CONCLUSIONS The MSRSGC can be reliably applied to pediatric salivary gland FNA. The ROM of each MSRSGC category in pediatric salivary gland FNA is relatively similar to the ROM of each category in adult salivary gland FNA, although the reported rates for the different MSRSGC categories are variable across institutions.

Abstract
Genetic intra-tumour heterogeneity fuels clonal evolution, but our understanding of clinically relevant clonal dynamics remain limited. We investigated spatial and temporal features of clonal diversification in clear cell renal cell carcinoma through a combination of modelling and real tumour analysis. We observe that the mode of tumour growth, surface or volume, impacts the extent of subclonal diversification, enabling interpretation of clonal diversity in patient tumours. Specific patterns of proliferation and necrosis explain clonal expansion and emergence of parallel evolution and microdiversity in tumours. In silico time-course studies reveal the appearance of budding structures before detectable subclonal diversification. Intriguingly, we observe radiological evidence of budding structures in early-stage clear cell renal cell carcinoma, indicating that future clonal evolution may be predictable from imaging. Our findings offer a window into the temporal and spatial features of clinically relevant clonal evolution.

Advancement in technology has given students and institutes an educational, interactive, and diagnostic aid with virtual reality functionality known as the Anatomage table. This review analyses the various spheres of the medical field where the 3D virtual tool is being used and assesses its acceptability, convenience, and practical application. A search for relevant studies in various databases namely Pubmed, Embase, Wiley Library, and Google Scholar was performed, and the data was compiled to understand the use of the Anatomage table. The search yielded a total of 24 studies that focused on the use of the Anatomage table. Eleven articles focused on using Anatomage as a learning tool and 13 described the perception of the Table. Anatomage table offers an excellent tool for learning anatomy by virtual dissection. The tool is not only used as a teaching aid, but also as a diagnostic and planning tool in residency programs. Adding the tool as an educational aid boosts the existing curriculum and helps to counter the challenges with cadaveric dissection. The equipment cost and its maintenance charges may be a deciding factor for the underutilization of the tool in developing countries.

Abstract
Diagnostic uncertainty may occur with almost any entity on cytological evaluation, depending on the quality and quantity of the provided sample. In serous fluid cytopathology, until recently, there had been no defined or agreed criteria for atypia and suspicious categories. Historically, the two descriptive terms appear to have been used almost interchangeably. The international system for serous fluid cytopathology is the first attempt by an expert international authorship to suggest the scenarios in which these terms are used and propose some diagnostic criteria and clinical management strategies.

Odderon Exchange from Elastic Scattering Differences between pp and pp[over ¯] Data at 1.96 TeV and from pp Forward Scattering Measurements. Phys Rev Lett 2021; 127:062003.

Abstract
We describe an analysis comparing the pp[over ¯] elastic cross section as measured by the D0 Collaboration at a center-of-mass energy of 1.96 TeV to that in pp collisions as measured by the TOTEM Collaboration at 2.76, 7, 8, and 13 TeV using a model-independent approach. The TOTEM cross sections, extrapolated to a center-of-mass energy of sqrt[s]=1.96 TeV, are compared with the D0 measurement in the region of the diffractive minimum and the second maximum of the pp cross section. The two data sets disagree at the 3.4σ level and thus provide evidence for the t-channel exchange of a colorless, C-odd gluonic compound, also known as the odderon. We combine these results with a TOTEM analysis of the same C-odd exchange based on the total cross section and the ratio of the real to imaginary parts of the forward elastic strong interaction scattering amplitude in pp scattering for which the significance is between 3.4σ and 4.6σ. The combined significance is larger than 5σ and is interpreted as the first observation of the exchange of a colorless, C-odd gluonic compound.

Abstract
BACKGROUND Small round cell tumors (SRCTs) are a broad category of diverse malignant tumors composed of monotonous undifferentiated cells. Involvement of serous fluids by SRCT is rare; however, the identification of exfoliated malignant cells is a crucial component of management and has significant implications for treatment and prognosis. The most common effusion tumors with SRCT morphology include Ewing sarcoma, synovial sarcoma, rhabdomyosarcoma (RMS), small-cell neuroendocrine carcinoma (SCNC), and desmoplastic SRCT, and the cytomorphologic distinction between these tumors is challenging. The purpose of this article is to describe the morphologic features of the most common SRCT in fluids and propose helpful ancillary testing. SUMMARY Effusion SRCTs display similar primitive and undifferentiated morphologic features although each has subtle variations. Ewing sarcoma is a mesenchymal neoplasm and harbors characteristic translocations t(11;22) (EWSR1-FLI1) or t(21;22) (EWSR1-ERG). In fluids, Ewing sarcoma shows poorly differentiated cells of variable size with round to oval nuclei, prominent nucleoli, and scant cytoplasm. In contrast, synovial sarcoma typically involves extremities and expresses a fusion transcript in t(X;18) (SS18-SSX). This soft tissue neoplasm demonstrates uniform cells with irregular nuclear contours, characteristic nuclear folding, and scant cytoplasm. RMS is a neoplasm arising from skeletal muscle, and the alveolar subtype demonstrates a translocation in t(2;13) (PAX3-FOXO1). The malignant cells show a spectrum of small round cells and pleomorphic large cells with rhabdoid morphology. RMS cells characteristically express myogenin and MyoD1, markers of skeletal muscle differentiation. Although SCNC is not a classic SRCT, the morphology is similar. SCNC demonstrates tight clusters of malignant cells with nuclear molding and salt-and-pepper chromatin. This tumor classically has neuroendocrine differentiation and is positive for synaptophysin and chromogranin on immunohistochemistry. And last, desmoplastic SRCT typically presents as an intra-abdominal mass in young men and characteristically harbors the translocation t(11;22) (p13;q12) (EWSR1-WT1). Cytomorphologically, the tumor shows small monomorphic cells occasionally arranged as rosette-like structures. KEY MESSAGE The diagnosis of SRCT can be made in effusion samples and is best achieved with a combination of morphologic features, clinical history, and ancillary testing.

Abstract
The genetic evolutionary features of solid tumour growth are becoming increasingly well described, but the spatial and physical nature of subclonal growth remains unclear. Here, we utilize 102 macroscopic whole-tumour images from clear cell renal cell carcinoma patients, with matched genetic and phenotypic data from 756 biopsies. Utilizing a digital image processing pipeline, a renal pathologist marked the boundaries between tumour and normal tissue and extracted positions of boundary line and biopsy regions to X and Y coordinates. We then integrated coordinates with genomic data to map exact spatial subclone locations, revealing how genetically distinct subclones grow and evolve spatially. We observed a phenotype of advanced and more aggressive subclonal growth in the tumour centre, characterized by an elevated burden of somatic copy number alterations and higher necrosis, proliferation rate and Fuhrman grade. Moreover, we found that metastasizing subclones preferentially originate from the tumour centre. Collectively, these observations suggest a model of accelerated evolution in the tumour interior, with harsh hypoxic environmental conditions leading to a greater opportunity for driver somatic copy number alterations to arise and expand due to selective advantage. Tumour subclone growth is predominantly spatially contiguous in nature. We found only two cases of subclone dispersal, one of which was associated with metastasis. The largest subclones spatially were dominated by driver somatic copy number alterations, suggesting that a large selective advantage can be conferred to subclones upon acquisition of these alterations. In conclusion, spatial dynamics is strongly associated with genomic alterations and plays an important role in tumour evolution.

Abstract
When one talks about a healthcare organisation, in most instances it is an automatic assumption that we are talking about clinical personnel. This article addresses the critical role that non-clinical personnel played during the COVID-19 pandemic. In particular, the authors delineated the critical roles of the marketing department personnel in healthcare organisations. In light of the pandemic, in the future, there will be a greater need for unique training topics that were not even imagined in the years prior to 2020, and using the concepts of marketing, the authors have provided a list of the potential generic topics as well as how to assess its reach, effectiveness and value.

Abstract
Abstract
Background/Introduction
Abnormal thyroid hormone concentrations have been associated with adverse cardiovascular outcomes, but the relationship between thyroid dysfunction and specific heart failure phenotypes is less clear.
Purpose
To examine the association of thyroid dysfunction with the risk of incident HF in older adults without pre-existing HF.
Methods
We analyzed participants enrolled in the Atherosclerosis Risk in Communities (ARIC) study who attended the visit 5 examination (2011–2013). Participants with previous HF history, and participants treated with amiodarone, levothyroxine, and antithyroid medication were excluded. We used Cox regression models to assess the associations between serum thyroid indices (free thyroxine [FT4], total triiodothyronine [TT3], or thyroid stimulating hormone [TSH]) and incident adjudicated HF with reduced (HFrEF) and preserved (HFpEF) left ventricular ejection fraction. Continuous associations between TT3 and outcome were further assessed via Cox model using restricted cubic spline.
Results
Among 3349 participants (mean age 75±5 years, 56% women, 20% black), subclinical hypothyroidism was prevalent in 12% of participants and low T3 syndrome in 3%. Those with overt hypothyroidism (<1%) or hyperthyroidism (<1%) were not included in the analysis given the low prevalence. Over a median follow-up of 5.5 years, incident HF occurred in 198 subjects (5.9%) at a rate of 11.1 per 1000 person-years. Of these, 86 were HFrEF, 83 HFpEF, and 29 were unclassified HF. We observed an inverse association of TT3 level with risk of incident HFpEF, but not overall incident HF or incident HFrEF, after adjustment for clinical confounders and baseline NT-proBNP levels (HR per 1 SD 0.70, 95% CI 0.54–0.92; P 0.010) (Figure). Similar results were observed for the composite endpoint of incident HFpEF or all-cause death. No statistically significant associations were found between TSH or T4 levels and incident HF. Low T3 syndrome was associated with incident HFpEF, but not overall incident HF or incident HFrEF, after adjustment for clinical confounders (HR 2.71, 95% CI 1.08–6.82; P 0.035); however, its association was significantly attenuated after adjustment with NT-proBNP (HR 2.25, 95% CI 0.87–5.79; P 0.09). No statistically significant association was found between subclinical hypothyroidism and incident HF.
Conclusions
In a contemporary biracial cohort of older adults, serum T3 level was inversely associated with incident HFpEF hospitalization. T3 administration could be considered as a potential target in future clinical trials preventing HFpEF hospitalization.

Abstract
This paper reviews the challenges faced by cytology laboratories during the COVID-19 pandemic. Various safety guidelines regarding collection, handling, transport and sampling in cytology laboratory are presented. A brief literature overview of adapted changes regarding new safety techniques, processing, sampling techniques implemented by the cytology laboratories in this part of the world is presented. The use of cytology in COVID-19 patients is discussed. The authors have also tried to present the challenges and changes faced for training and education during this time. Migration from multi-headed scope in-person sign-out to digital based platforms were adapted to continue medical education. The potential long-term implications of these adaptations on cytology services are also touched upon.

Abstract
OBJECTIVE The global coronavirus disease 2019 (COVID-19) pandemic has necessitated rapid alterations to diagnostic pathways for head and neck cancer patients that aim to reduce risk to patients (exposure to the hospital environment) and staff (aerosol-generating procedures). Transoral fine needle aspiration cytology offers a low-risk means of rapidly diagnosing patients with oral cavity or oropharyngeal lesions. The technique was utilised in selected patients at our institution during the pandemic. The outcomes are considered in this study. METHOD Diagnostic outcomes were retrospectively evaluated for a series of patients undergoing transoral fine needle aspiration cytology of oral cavity and oropharyngeal lesions during the COVID-19 pandemic. RESULTS Five patients underwent transoral fine needle aspiration cytology, yielding lesional material in 100 per cent, with cell blocks providing additional information. In one case, excision biopsy of a lymphoproliferative lesion was required for final diagnosis. CONCLUSION Transoral fine needle aspiration cytology can provide rapid diagnosis in patients with oral cavity and oropharyngeal lesions. Whilst limitations exist (including tolerability and lesion location), the technique offers significant advantages pertinent to the COVID-19 era, and could be employed in the future to obviate diagnostic surgery in selected patients.

Abstract
INTRODUCTION Effusions can develop inside serous cavities in several pathologic states, both neoplastic and non-neoplastic. They are easy to drain and can provide useful diagnostic information. However, the reported diagnostic efficacy of these specimens has not been uniform across different laboratories. To standardize practices, the international system for reporting serous fluid cytology (TIS) was developed in accordance with the best international practices, the most up-to-date reported data, and expert consensus. RESULTS TIS has set the basic principles for laboratory handling of serous effusion specimens, defined the adequacy criteria, and set a standardized reporting terminology with well-defined criteria for each diagnostic category. These include nondiagnostic, negative for malignancy, atypia of undetermined significance, suspicious for malignancy, and malignant. Each can provide useful inherent information for appropriate clinical management and follow-up, with a defined expected diagnostic category incidence and risk of malignancy. CONCLUSIONS TIS applies to serous fluids collected from the pleura, peritoneal, and pericardial cavities. Using TIS, indeterminate categories are presented as either preliminary or as options of last resource. TIS has emphasized the role of ancillary tests in arriving at the correct interpretation within each category. It also has emphasized the importance of a malignant diagnosis as a definitive diagnosis, comparable to histologic examinations. Because of the well-documented outcomes in the adoption of uniform cytology terminology for other organ systems, we recommend the use of the upcoming TIS and believe its use will be paramount to improving the diagnostic yield in this area of cytology.

Abstract
OBJECTIVES To assess whether targeted cognitive freehand-assisted transperineal biopsies using a PrecisionpointTM device still require additional systematic biopsies to avoid missing clinically significant prostate cancer, and to investigate the benefit of a quadrant-only biopsy approach to analyse whether a quadrant or extended target of the quadrant containing the target only would have been equivalent to systematic biopsy. PATIENTS AND METHODS Patients underwent combined systematic mapping and targeted transperineal prostate biopsies at a single institution. Biopsies were performed using the Precisionpoint device (Perineologic, Cumberland, MD, USA) under either local anaesthetic (58%, 163/282), i.v. sedation (12%, 34/282) or general anaesthetic (30%, 85/282). A mean (range) of 24 (5-42) systematic and 4.2 (1-11) target cores were obtained. Magnetic resonance imaging (MRI) scans were reported using the Likert scale. Clinically significant cancer was defined as Gleason 7 or above. Histopathological results were correlated with the presence of an MRI abnormality within a spatial quadrant and the other adjoining or non-adjoining (opposite) quadrants. Histological concordance with radical prostatectomy specimens was analysed. RESULTS A total of 282 patients were included in this study. Their mean (range) age was 66.8 (36-80) years, median (range) prostate-specific antigen level 7.4 (0.91-116) ng/mL and mean prostate volume 45.8 (13-150) mL. In this cohort, 82% of cases (230/282) were primary biopsies and 18% (52/282) were patients on surveillance. In all, 69% of biopsies (195/282) were identified to have clinically significant disease (Gleason ≥3 + 4). Any cancer (Gleason ≥3 + 3) was found in 84% (237/282) of patients. Of patients with clinically significant disease, the target biopsies alone picked up 88% (171/195), with systematic biopsy picking up the additional 12% (24/195) that the target biopsies missed. This altered with Likert score; 73% of Likert score 3 disease was detected by target biopsy, 92% of Likert score 4 and 100% of Likert score 5. Target biopsies with additional same-quadrant-only systematic cores picked up 75% (18/24) of significant cancer that was missed on target only, found in the same quadrant as the target. CONCLUSION Systematic biopsy is still an important tool when evaluating all patients referred for prostate biopsy, but the need is decreased with increasing suspicion on MRI. Patients with very high suspicion of prostate cancer (Likert score 5) may not require systematic cores, unless representative surrounding biopsies are required for other specific treatments (e.g. focal therapy, or operative planning). More prospective studies are needed to evaluate this in full.

Abstract
Abstract
OnBehalf
The ARIC Study
Background
Age-related left atrial (LA) structural/functional abnormalities in elderly patients with normal sinus rhythm and preserved ejection fraction may precede the development of overt atrial fibrillation, and also may be related to stroke.
Purpose
To evaluate the association of 3-dimensional echocardiographic (3DE) atrial contractility parameters with subclinical cerebral infarcts (SCIs), as assessed by brain MRI, and clinically diagnosed stroke
Methods
We studied 407 participants (mean age 76 ± 5 years, 40.5% male) from the Atherosclerosis Risk in Communities Neurocognitive Study (ARIC-NCS) without AF and who underwent a brain MRI and a 3DE examination in 2011-13. We defined 3 groups: those with no cerebral infarcts on brain MRI (NCIs, N = 315); those with MRI-diagnosed SCIs (N = 58); and those with clinically diagnosed stroke (N = 34).
Results
While still within the normal range, LA indexed volume significantly increased across the 3 groups (P-trend = 0.01).This was accompanied by an increase in the LA global longitudinal strain (GLS), an echocardiographic index of LA reservoir function (P-trend = 0.004). E/e’ divided by LA GLS—index of atrial stiffness—worsened across groups (P-trend = 0.005) and was independently associated with SCIs and Stroke, pooled together, [OR per 1 %-1, 1.97; 95% CI (1.24, 3.11), P = 0.004], and Stroke [OR per 1 %-1, 2.30; 95% CI (1.23, 4.30), P = 0.009]. LA GLS was marginally associated with an increased odd of SCIs [OR per 1 %, 1.07; 95% CI (1.01, 1.13), P = 0.014].
Conclusions
Among elderly participants with normal sinus rhythm and preserved ejection fraction in a large cohort study, markers of LA function and stiffness are associated with increased odds of subclinical infarcts and stroke. These data suggest that even subtle LA dysfunction, which may contribute to LA stasis, may predispose to subclinical cerebral infarcts and stroke.

Abstract
INTRODUCTION Sepsis results in immunologic disturbances with the release of various inflammatory mediators such as cytokines. Cytokines can damage the cells, and the continuous release of inflammatory mediators leads to severely impaired immunity. Therefore, the reduction in cytokine levels by hemoadsorption represents a new concept for blood purification. CytoSorb® as a hemoadsorption device is a detoxification system, which aims to decrease the cytokines levels. This study was conducted to understand any beneficial effects of CytoSorb® therapy in septic patients. METHODOLOGY This was a retrospective and observational study, approved by the scientific and ethics committee of Max Super Specialty Hospital, Patparganj, Delhi, India and conducted in compliance with current International Council for Harmonization, Good Clinical Practice, Schedule Y, and Indian Council of Medical Research guidelines. Subjects of either gender (age > 18 year) were included in the study. The data were presented as mean ± standard deviation and categorical as frequency and percentage (%). A p value less than 0.05 (p < 0.05) was considered to be statistically significant. RESULTS A total number of 36 patients were included in the study. Majority of the patients were male with mean age (56.36 ± 14.83). After therapy, procalcitonin and total leucocyte count levels decreased within 24 h. Post therapy, sepsis-related organ failure assessment (SOFA) score of Day (D)1, D2, and D3 reduced to 10.4 ± 3.63, 8.7 ± 4.02, and 7.8 ± 3.67, respectively. The Acute Physiology and Chronic Health Evaluation (APACHE) II score and predicted mortality were lower in the survivor group as compared to the non-survivor group. CONCLUSION Hemoadsorption using the extracorporeal adsorption device (CytoSorb®) might be an effective rescue therapy in stabilizing septic shock patients.

Abstract
Abstract
An interlaboratory study was conducted for evaluation of a method to determine the flavonol aglycones quercetin, kaempferol, and isorhamnetin in Ginkgo biloba products. The method calculates total glycosides based on these aglycones formed after acid hydrolysis. Twelve matrixes were chosen for study by 12 collaborating laboratories in 2 countries. Test materials included crude leaf material, standardized dry powder extract, single and multiple entity finished products, ethanol and glycerol tinctures, and National Institute of Standards and Technology (NIST) standard reference materials (SRMs). Results from 11 laboratories were used for the final calculations. Eight of the 12 matrixes evaluated produced acceptable results for total flavonol glycosides, with HorRat scores ranging from 1.31 to 2.05; repeatability relative standard deviations (RSDr) from 1.46 to 4.14; and reproducibility relative standard deviations (RSDR) from 4.67 to 9.69. These 8 matrixes consisted primarily of simple dosage forms (e.g., dry powder extracts, crude leaf samples, liquid extracts, and SRMs) and a single tablet product (Ginkgo Awareness). Four additional matrixes, consisting of 3 tablets and 1 soft gel product (Ginkgold, Ginkoba, Ginkogen, and Ginkgo Phytosome, respectively), showed greater total flavonol glycoside HorRat scores in comparison, ranging from 2.39 to 5.13, with RSDr values from 2.83 to 8.16, and RSDR values from 8.53 to 20.4. Based on the results presented here, the method is recommended for Official First Action for determination of total flavonol glycosides calculated from quercetin, kaempferol, and isorhamnetin in dry powder extracts, crude leaf material, liquid extracts, and a select finished product, Ginkgo Awareness.

Abstract
INTRODUCTION The International System for the Reporting of Serous Fluid Cytopathology was initiated to provide a common language for cytopathology reports on body fluids. MATERIALS AND METHODS The International Academy of Cytology and the American Society of Cytopathology collaborated to provide evidence-based and expert-driven terminology for reporting serous fluids. Lead editors were selected and expert authors invited to form working groups for the diagnostic categories and special sections. RESULTS Preliminary results of the collaboration include the 6 diagnostic terminology categories: non-diagnostic, negative for malignancy, atypia of undetermined significance, suspicious for malignancy, malignant-primary, and malignant-metastatic. Four special sections on ancillary testing, peritoneal washings, cytotechnical aspects, and quality assurance will appear in the final text. Initial results of an international survey indicate strong support for a uniform terminology for reporting serous fluids. CONCLUSIONS This article outlines the initial findings of the collaboration as presented to the United States and Canadian Academy of Pathology at the 2019 annual meeting at the National Harbor, MD.

Abstract
Serous fluids are a common but important specimen type in a cytopathology laboratory. There is as yet no agreed standardized terminology to allow uniformity in reporting on these specimens. Given that serous fluids are a rich source of cytopathological as well as molecular information on a range of benign and often advanced malignant conditions, a unified approach to handling and reporting these specimens covering the pre-analytical, analytical and postanalytical stages seems timely. Representatives of the international cytology community have come together once again to develop an algorithmic diagnostic and management approach to the reporting of these samples.

Abstract
The GRAPES-3 muon telescope located in Ooty, India records rapid (∼10 min) variations in the muon intensity during major thunderstorms. Out of a total of 184 thunderstorms recorded during the interval of April 2011-December 2014, the one on December 1, 2014 produced a massive potential of 1.3 GV. The electric field measured by four well-separated (up to 6 km) monitors on the ground was used to help estimate some of the properties of this thundercloud, including its altitude and area that were found to be 11.4 km above mean sea level and ≥380 km^{2}, respectively. A charging time of 6 min to reach 1.3 GV implied the delivery of a power of ≥2 GW by this thundercloud that was moving at a speed of ∼60 km h^{-1}. This work possibly provides the first direct evidence for the generation of gigavolt potentials in thunderclouds that could also possibly explain the production of highest-energy (100 MeV) gamma rays in the terrestrial gamma-ray flashes.
