(Based on the materials from the archive of the Department of Social Hygiene of Kazan University) ..
Another old doctor-populist and social activist, the glorious son of Kazan University, V Ladimir Nikolaevich Zolotnitsky, has passed away; left at a ripe old age - 77 years old, but continued to work almost until his last days. His work until his last days was to take an active interest in the life of the present and the past. In particular, he was keenly interested in the anniversary of our university. One of the first responded to my letter "To old doctors - citizens of Kazan" on the occasion of the anniversary with a request to send materials to the history of the university, VN was one of the first to respond. During January and February of this year, he corresponded with me; he delivered valuable materials about his life to our department , memories of the past, sent all his published works. He put me in touch with Prof. A?. V. Portugalov, the son of a scholar, writer - publicist, until the anniversary and will be a guest of honor at this university festival as the oldest student of the university. But the laws of biology decided otherwise: V.N.Zolotnitsky celebrated his 50th anniversary of medical and social activity, celebrated the 75th anniversary of his life, celebrated the formal historical date of the 125th anniversary of his university, but did not live 21/2 months before the solemn anniversary.

Dr. N.V. Busygin. Transplant of eyes taken from a corpse (experimental study). The speaker, having acquainted with the literature on the issue of eye transplantation, noted the absence of indications for eye transplantation taken from the corpse. The main factor in the death of transplanted eyes in animals is, as the speaker's experiments showed, trauma, so the question of transplantation can only be resolved by homoplastic operations performed on humans (the heteroplasty of the eyes used so far, for obvious reasons, has not yielded results).

Evaluation of thrombocytopenia: A single-center experience
Authors: Patel Swati , Sinha Avantika 
Published: September 2021

To evaluate the common etiologies and bleeding manifestations in patients of thrombocytopenia and its clinical presentation, methods of investigation, and impact of various modes of management. Total 104 patients with platelet count less than l00,000 per cu.mm. with age, more than 12 years admitted to hospital between January 2010 to October 2011 were included in this study. Platelet count on automated cell counter less than 100,000 per cu.mm. and confirmed in peripheral smear were included in the study. All EDTA samples were processed in Abacus junior 5 hematology Analyser. Peripheral blood smear review was done for all cases. Clinical history and physical examination were collected from patients and medical record files.The present study included 56 male patients and 48 female patients. The most common bleeding manifestation was petechial rash 8.6%, hemoptysis and traumatic bleeding account for 1.9 % each, whereas 74% of patients did not present with any bleeding issues. Total 66 patients presented with symptoms of fever, 73 had signs of pallor, 22 patients had splenomegaly, 16 patients had hepatomegaly. Total 37.5% of patients were diagnosed with malaria and 1 patient (0.96%) was diagnosed with plasma cell leukemia. Chronic liver disease, megaloblastic anaemia, ITP (Idiopathic thrombocytopenia) and chronic renal failure account for 9.6%, 13.4%, 5.7% and 3.8% respectively. Total 16 patients had platelet counts less than 20000/cu.mm. and 37 patients had platelet count between 60000-80000/cu.mm. Malaria (39 patients) was the major cause of thrombocytopenia. Out of 39 patients with malaria 10 patients had P. Falciparum, 27 had P. Vivax and 2 patients had both. Patients with a platelet count less than 100,000/cu.mm have very high chances of bleeding manifestation. Cutaneous bleed is the most common manifestation. Malaria can be present with signs of thrombocytopenia. Timely and accurate diagnosis is the key to the management of thrombocytopenia.
T-Lymphoblastic lymphoma presenting with obstructive jaundice and pleural effusion; role of flow cytometry on pleural fluid: A case report
Authors: P Awasthi Namrata , S Anshima 
Published: September 2021

T-cell lymphoblastic lymphoma often presents as a large mediastinal mass in the anterior mediastinum with shortness of breath as chief complaint. We, put forward a case of T-LBL, presenting with obstructive jaundice and, later developing pleural effusion. Diagnosis was clinched by Flow Cytometry (FCM) performed on the pleural fluid, which revealed, neoplastic lymphoid cells; suggesting T-cell Lymphoproliferative disorder.Bone marrow examination and immunohistochemistry revealed CD3+, TDT+, CD10+, CD34- and CD20- blasts. Thus, diagnosis of T-ALL/LBL was rendered. Clinicians should be mindful that TALL/LBL can uniquely present with obstructive jaundice, proffering serious diagnostic dilemma. FCM should be attempted on any available body fluids/effusions, in appropriate clinical settings, as it can contribute substantially, in making a rapid diagnosis and, initiating early therapy. 1. Leukemia/lymphoma should be considered in the differential diagnoses, when the initial work-up for obstructive jaundice, is inconclusive; 2. FCM can be performed on any fluid/effusion sample for hematolymphoid neoplasm and can aid in making a rapid diagnosis.
Primary squamous cell carcinoma of renal pelvis and kidney- Sole diagnosis by histopathology
Authors: Prachi  , Sharma Gaurav , Jain Vikas 
Published: September 2021

Primary Squamous cell carcinoma of the renal pelvis is rare and accounts to only 0.5- 0.8 % of malignant renal tumours having poor prognosis. Chronic irritation, inflammation and infection induce the pathogenesis of this malignancy. A 53 year old male patient, presented with left flank pain since one month. On radiological investigation, his CT revealed atrophic shrunken left kidney measuring 7.9x5.2cms showing significant parenchymal thinning and complete loss of corticomedullary differentiation. A left upper ureteric calculus is seen measuring 7.5 mm with significant left renal hydronephrosis.Clinically, it was diagnosed as Xanthogranulomatous Pyelonephritis. Grossly the radical nephrectomy specimen measures 10.5x5.5x3.5cm. External surface is irregular & bosselated. On Cut surface renal architecture is effaced by necrotic mass measuring 9.5x5.0x3.0 cm involving pelvic ureter and most of renal parenchyma.Hematoxylin and eosin stained tissue revealed characteristic feature such as keratin pearls and intracellular bridges seen, rendering the diagnosis of well-differentiated keratinising squmaous cell carcinoma seen with 40% tumour necrosis associated with Keratinizing Squamous Dysplasia. In the present case, obstructive uropathy has triggered the event of malignancy. The radiologic differential diagnosis includes primary and secondary renal neoplasms and xanthogranulomatous pyelonephritis associated with renal calculi. XGP is commonly associated with lithiasis however, rarely causes keratinizing squamous metaplasia and its manifestations closely mimic renal neoplasm, leading to misdiagnosis of malignancy.The prognosis is dismal with a 5-year survival rate of &#60;10%. CT and MRI play a crucial role in diagnosis and staging of these tumors, though histology always remains confirmatory and diagnostic.

Authors: Mandysova Petra , Herr Keela 
Published: September 2021

Background and PurposePain is a frequent yet underdiagnosed problem in patients with stroke due to stroke-related cognitive limitations that may hamper effective usage of pain tools. The Revised Iowa Pain Thermometer-Czech (IPT-R-CZ) is a linguistically validated translation of an English-language self-report pain instrument; however, the psychometric properties of the Czech version are unknown. This study aimed to psychometrically evaluate the IPT-R-CZ in cognitively intact and impaired Czech-speaking patients with stroke.MethodsFifty-four patients rated their pain intensity using the IPT-R-CZ, the Faces Pain Scale-Revised, and the Numerical Rating Scale, ranking them in terms of usability. Results: Correlations among pain scores across the tools were very strong. The IPT-R-CZ ranked first in terms of usability.ConclusionConvergent validity, test-retest reliability, and usability of the IPT-R-CZ in Czech-speaking cooperative patients with stroke were acceptable.

Background and PurposeAutonomy in nursing practice is one of the recurring fields in literature of research. For nurses to be autonomous is considered to have a great importance on the quality of healthcare services. This study aimed to examine the validity and reliability of the Turkish version of the Attitude Toward Professional Autonomy Scale for Nurses.MethodsThis methodological study adopted a descriptive cross-sectional design. The study was done in a secondary care hospital. Sample group includes 199 nurses that work at a secondary care hospitals. It was carried out while culturally adjusted and it also included two-way translations of English version of the Attitude Toward Professional Autonomy Scale for Nurses. To evaluate its validity, LISREL statistics software was used to make confirmatory factor analysis.ResultsInternal consistency was evaluated by using Cronbach’s α and total-item correlations. Average age of the sample group was found 28.35 ± 6.16. Confirmatory factor analysis yielded t-scores, which were significant for all the 18 items (p < .05). Fit indices of the model, resemblance rate chi-square statistics were identified as χ2/df = 198.01/132 = 1.50. The Cronbach’s alpha of the scale (.918) was indicative of strong internal consistency.ConclusionsThe scale demonstrated strong validity and internal consistency. This scale can be used to assess perceptions of nursing practices that enhance the quality of nursing care.

Authors: Heaney Alice , McKenna Stephen P. , Hagell Peter 
Published: September 2021

Background and PurposeThe Unidimensional Fatigue Impact Scale (U-FIS) was developed for use in a multiple sclerosis population. The aim was to determine whether the U-FIS is a valid tool for measuring the impact of fatigue in Crohn’s disease (CD).MethodCD patients completed the U-FIS as part of a validation study of the Crohn’s Life Impact Questionnaire (CLIQ). Data were analyzed according to Rasch measurement theory (RMT).ResultsTwo hundred sixty-one completed U-FIS questionnaires were available for analysis. After rescoring the items to resolve disordered thresholds, all 22 items showed acceptable RMT fit. However, there was considerable local item dependency (LID).ConclusionThe U-FIS did not provide unidimensional measurement in a sample of CD patients due to high levels of LID. Combining the three FIS outcomes into a single measure was not justified.

Published: September 2021

Case:
An 83-year-old man suffered progressive lower back pain 4 weeks after an endovascular aortic repair (EVAR) procedure. Computed tomography showed L4 vertebral body collapse and abnormal soft tissue-like density swelling with increased uptake on 18F-fluoro-D-glucose (FDG) positron emission tomography (PET)/CT. Listeria monocytogenes was identified from ultrasound-guided fine-needle aspiration. Ultrasound-guided drainage of the retroperitoneal abscess and intravenous antibiotic therapy with ampicillin and gentamicin resulted in the rapid relief of symptoms.

Conclusion:
Spondylodiscitis after EVAR requires a timely diagnosis. Uncommon organisms such as L. monocytogenes must be suspected, even in focal infections without signs of listeriosis. Conservative treatment with preservation of the graft should be considered as long as close follow-up evaluations are performed.

Time to resuscitate cardiopulmonary resuscitation! The 3R/CPR: Refill-Recoil-Rebound.
Authors: Nour Sayed 
Published: September 2021

Abstract
Introduction Sudden cardiac arrest (SCA) remains a major health issue worldwide with gloomy outcomes due to poor perfusion of cardiopulmonary resuscitation (CPR), deemed unsuitable for hemostatic conditions, cardiotorsal anatomy, electrophysiology and thoracic biomechanics. Alternatively, we propose a new management, implementing rational mobilization of stagnant blood: manually with a novel technique of cardiac massage and mechanically with a circulatory flow restoration (CFR) device. Methods Simulated chest compressions were performed through the 5th intercostal space in professional Lifeguards volunteers, placed in the left lateral decubitus position with raised legs and abdominal compression. Expected results Compared to CPR, bypassing the sternal barrier, refilling the heart and then compressing the chest with a recoil-rebound maneuver (3R / CPR) can significantly promote ROSC. Results of CFR device were previously demonstrated. Conclusion 3R/CPR adapts human morphology promoting adequate perfusion and ROSC safely, under all circumstances. Preclinical computational models can confirm the effectiveness of 3R/CPR versus CPR.

Abstract
Nowadays with the development of technology and access to the Internet everywhere for everyone, the interest to get the news from newspapers and other traditional media is decreasing. Therefore, the popularity of news websites is ascending as the newspapers are changing into electronic versions. News websites can be accessed from anywhere, i.e., any country, city, region, etc. So, the need to present the news depends on where the reader is from can be a research area, as with facing with variety of news topics on websites readers prefer to choose those which more often show the news, they are interested in on their home pages. Based on this idea we represent the technique to find favorite topics of Twitter users of certain geographical districts to provide news websites a way of increasing popularity. In this work we processed tweets. It seems that tweets are some small data, but we found out that processing this small data needs a lot of time, due to the repetition of the algorithm a lot and many searches to be done. Therefore, we categorized our work as big data. To help this problem we developed our work in the Spark framework. Our technique includes 2 phases; Feature Extraction Phase and Topic Discovery Phase. Our analysis shows that with this technique we can get the accuracy between 68% and 76%, in 3 developments 3-fold, 5-fold, and 10-fold.

Abstract
Objective To assess the value of left atrium volume index（LAVI）for diagnosing heart failure with preserved ejection fraction (HFpEF) based on the invasive determination of left ventricular end-diastolic pressure (LVEDP).Methods A total of 710 cases of patients with dyspnea (LVEF≥50%) were enrolled in this retrospective study. Left ventricular end-diastolic pressure (LVEDP) was measured through selective coronary angiography. According to the value of LVEDP, cases were divided into the HFpEF group ( LVEDP≥15mmHg) and the control group (LVEDP<15mmHg). LAVI was calculated based on cardiac compartment diameter, as measured by echocardiography, and body surface area (BSA). Differences of LAVI between the HFpEF group and the control group, and between subgroups in the HFpEF group were analyzed.Results The difference in LAVI between the control group and the HFpEF group was statistically significant (41.35±2.28vs.46.78±2.63ml/m2, p=0.008). LVEDP was positively correlated with LAVI (Pearson: r=0.787, P＜0.001). When LAVI took the best cutoff value of 43.7 mm/m2, the sensitivity and specificity of diagnosis of HFpEF were 92.0% and 88.9%. When the boundary value of LAVI was from 41.7 to 45.7 mm/m2, the sensitivity of the diagnosis of ejection fraction retention heart failure was from 97.4% to 64.4% and the specificity was from 51.2.0% to 92.2%.Conclusion In patients with dyspnea after exclusion of heart failure with reduced ejection fraction (HFrEF), LAVI is positively correlated with LVEDP. LAVI can be used to diagnose HFpEF when HFrEF is excluded.
