Aim. The study of the structural and functional properties of arteries in patients after a coronavirus disease 2019.Material and methods. The study included 113 people: 45 people who were examined before the start of the COVID-19 pandemic, healthy individuals who had COVID-19 (n=44), 24 patients with hypertension (HTN) in combination with prior COVID-19. In the individuals included in the study, the blood tests were performed, while the carotid arteries were evaluated using high-RF signal technology, applanation tonometry, volume sphygmography, and a test with post-occlusive reactive hyperemia were performed.Results. According to the study of carotid arteries, significant differences were registered between groups of healthy individuals (with and without a history of COVID-19) and HTN patients after COVID-19. According to the applanation tonometry in patients with hypertension and COVID-19 in history, aortic pressure and carotid-femoral pulse wave velocity significantly exceeded those in cohorts of individuals without cardiovascular diseases. According to the results of volume sphygmography in the group of patients after COVID-19, signs of early vascular aging were revealed, and the maximum values of these indicators were recorded in the group of hypertensive patients.Conclusion. The results obtained in the course of this study make it possible to state an increase in the arterial stiffness in people after COVID-19, which can be regarded as a sign of early vascular aging.
Rumination as a Transdiagnostic Notion
Authors: SÜRÜ Dilara 
Published: June 2023

Transdiagnostic, in other words ‘beyond diagnosis’ is a term that which is generated as an alternative to some negative situations which are caused by diagnostic approach. Transdiagnostic approach is a comprehensive perspective which adopts diagnosis as a tool and crossover rather than the main purpose.
Rumination means that repetitive and compulsory thoughts which provokes a lot of negative cicumstances. Runimation is seen in many psychopathologic diagnosis as symptom even it is not mentioned as an exact diagnosis in the literature. Some notions like rumination which are not described as exact diagnosis but provide some criterias which are seen as general psychopathologic symptoms qualified as transdiagnostic. The aim of this study is evaluating rumination in the concept of transdiagnostic view by reviewing literature and discussing its advantages.
Studies show that ruminations effects on many diagnoses persistence, occurance and relapse like depression, anxiety, stress, alcohol addiction and substance addiction helps to understand transdiagnostic feature of itself. At the same time, factors like adding a meaning to evaluation of the relationship between diagnoses, occuring important effects on consistence of diagnosis as being mediator role and implicit role provide a view to understand transdiagnostic charasteristic of rumination. To sum up, by handling rumination as a transdiagnostic notion some criterias are aimed such as influencing to symptoms and diagnosis which are caused and continued by rumination.

Authors: M Baskaran , A Jayasudha 
Published: June 2023

Background/Aim: The increasing prevalence of obstructive sleep apnea (OSA) necessitates the timely diagnosis and treatment of patients. Knowledge of OSA is limited among student doctors and nurses. Hence, we assess the level of knowledge regarding OSA among nursing students and evaluate effectiveness of a structured teaching program on the same.
Methods: This was a quasi-experimental research study, that included 90 nursing students, selected by purposive sampling. They were asked to fill out questionnaire consisting of questions regarding OSA, followed by a structured training program about OSA. They were assessed for level of knowledge regarding OSA post-test.
Results: Mean knowledge score pre-test was 5.39±3.37, and post intervention was 15.9±2.45 (P =0.0001). Majority of the students (82.2%, n=74) had no prior knowledge about OSA, and none had adequate knowledge pre-test. Post-test majority had adequate knowledge (71.11%, n=64). Having prior knowledge about OSA pre-test was significantly associated with increased level of pre-test knowledge (P =0.0001).
Conclusion: The knowledge of OSA among nursing students was inadequate, but the structured training program substantially increased their level of knowledge.

The period of observation: from 2019 until the May 20, 2022; 48 and 51 patients were primary observed before and 6 months after LRP + CIIA + UCA and TURP. Criteria of inclusion: prostatic volume 60–80 cm3.Pre-operative treatment included such parameters as prostate-specific antigen level. Volume of prostate, volume of residual urine, urodynamic parameters, IPSS (International Prostate Symptom Score) + quality of life (QoL) scale result. Postoperative observation after 6 months included uroflowmetry, residual urine volume, evaluation of lower urinary tract symptoms and their influence on IPSS and QoL scale result. Efficacy of treatment of BPH is a summary of all earlier described parameters.Results. Symptomatic regression in patients who underwent LRP + CIIA + UCA and TURP was found among 15 (93.75 %) and 13 (81.25 %) patients relatively; complications distributed throughout 1, 2 and 3 classes by Clavien-Dindo criteria: after TURP – among 71.4, 22.9 and 5.7 % patients, after LPA + CIIA + UCA – among 35.4, 24.2 and 11.3 %, relatively. After 6 months maximal urine flow improved up to 22.7 ± 2.2 ml/seс, 16.8 ± 1.5 ml/seс, relatively.Conclusion. LRP + CIIA + UCA is effective for urodynamic and life quality improvement like TURP. LRP + CIIA + UCA has shown statistically significant advantages of such parameters as blood loss, bladder neck contractures and urethral strictures.

Published: June 2023

Aim. This study aimed to describe a distinct subpopulation of azoospermic patients with isolated elevation of follicle-stimulating hormone (iFSH) and poor outcomes of microdissection testicular sperm extraction (microTESE).Materials and methods. A retrospective analysis of microTESE outcomes was conducted among 565 patients with non-obstructive azoospermia (NOA). Testicular pathology was assessed by the dominant histological pattern and Bergmann–Kliesch score (BKS). Descriptive statistics were presented for the iFSH subgroup. Inhibin B levels, the sperm retrieval rate (SRR), and BKS were compared in iFSH patients and other NOA patients.Results. The overall SRR was 33.3 % per microTESE attempt. The median BKS was 0.6 (interquartile range 0–2). Of all NOA patients, 132 had iFSH, and microTESE was successful only in 11 of those cases, with an SRR of 8.3 %, while the total SRR in other NOA patients was 38.1 % (p <0.001). iFSH had a sensitivity of 32.1 % (95 % confidence interval 27.4–36.8) and specificity of 94.1 % (95 % confidence interval 90.8–97.5) as a predictor of negative microTESE outcomes.Conclusion. Patients with iFSH may harbor a distinct testicular phenotype with total loss of the germ cell population and poor outcomes of surgical sperm retrieval.

Tuberculous mastitis and invasive breast cancers are known to co-exist or occur in the breast independently of each other, albeit the former being less common in developed countries. Tuberculous mastitis with its clinical presentation and morphological features can caricature invasive breast carcinoma. The overlapping features of tuberculous mastitis and metaplastic squamous cell carcinoma often lead to, if no due clinical diligence and discretion is used, bewildering misinterpretation with the vicissitude of diagnostic implications of tuberculous mastitis ensuing catastrophic and perilous ramifications. A 42-year-old woman presented with exophytic growth with extensive areas of ulceration. Clinically, the lesion was diagnosed as disseminated tuberculous mastitis based on clinical and morphological features, which was surgically resected. On histological examination, the lesion was diagnosed as invasive metaplastic squamous cell carcinoma. Thecase being presented here displays the vagary involved in clinical diagnosis of tuberculous mastitis inasmuch as it often shares clinical and morphological features with a devastatingly perilous variant of invasive duct carcinoma, metaplastic squamous cell carcinoma, the inadvertent eschewing of or misapprehending of which may engender devastating prognostic implications.

Published: June 2023

<p>O Brasil é o terceiro maior produtor de caulim do mundo e, junto com os Estados Unidos, detêm mais de 80% de reserva mundial de caulim de valor econômico. Caulim é uma argila, constituído basicamente de caulinita, Al2Si2O5(OH)4, usada em diversas aplicações industriais. Nos Estados da Paraíba e Rio Grande do Norte, as indústrias de processamento de caulim fazem parte de um setor econômico importante, no entanto, geram uma grande quantidade de resíduos, que são fonte de contaminação e poluição do ambiente. Aproximadamente 40 zeólitas naturais têm sido caracterizadas, mas na busca de novos materiais, mais de 150 estruturas sintéticas têm sido desenvolvidas. Por muitos anos as zeólitas têm sido úteis para troca iônica seletiva e peneiras moleculares para separar moléculas de diferentes tamanhos e formatos. Recentemente, as pesquisas têm focado os estudos na produção de zeólitas catalíticas. O presente trabalho tem como objetivo principal a síntese de zeólitas a partir do rejeito de caulim coletados de diferentes pontos nos Municípios de Junco do Seridó-PB e Equador-RN. As amostras devidamente secas e pesadas foram submetidas ao quarteamento, peneiramento e em seguida analisadas, quanto à distribuição granulométrica. Para a obtenção das zeólitas desejadas, utilizou-se um processo hidrotermal de baixo custo. Os materiais sintetizados, bem como o rejeito caulinítico, foram caracterizados por difração de raios-X (DRX) e espectroscopia na região do infravermelho (FTIR).</p>

Published: June 2023

Introduction: Coronavirus disease 2019 (COVID-19) was first reported in 2019 and has since become a health concern due to its rapid spread and high mortality rate. With the discovery of vaccines, there has been a reduction in disease occurrence, transmission, mortality, and morbidity in a population. However, with the emergence of newvariants, the available vaccines show varying efficiencies depending on the population and variants, while the present drugs may lose their effectiveness, hence the urgent need to explore effective therapies. Mesenchymal stemcells (MSCs) have been widely studied for their anti-inflammatory and immunomodulatory effects as COVID-19treatment and shown their potential to improve the condition of COVID-19 patients. This systematic review aims to assess the therapeutic potential of MSCs as anti-inflammatory and immunomodulatory agent in COVID-19.
Materials and Methods: A literature search is performed on PubMed, ScienceDirect, ProQuest, and Google Scholar and potentially relevant studies to review, based on the inclusion and exclusion criteria we have determined.We identified 14,090 publications from our search and excluded duplicates as well as irrelevant studies from title,abstract, and full-text screening. Data extraction and analysis were then performed in the 20 eligible studies.
Results and Discussion: Results show that MSCs improve immune system dysregulation throughimmunomodulatory and anti-inflammatory effects, through reducing blood C-reactive protein (CRP) and IL-6 levels.
Conclusion: We conclude that MSC is one of the promising treatments in COVID-19 regardless of variants.

Published: June 2023

Background: We aimed to establish the cut-off value of weight-for-height for preschool children in China, and to explore the influence of overweight and obesity on the physical performance of preschool children.
Methods: Data from 31 provinces in China monitored in 2010 and 2014, the standard deviation unit curves of WFH were established by using GAMLSS (generalized additive model for location, scale, and shape) method preschool children in China, and then the cut-off values of normal weight, overweight and obesity were divided. The research group tested 5 physical performance indicators of 5154 preschool children from April 2018 to June 2019 in Beijing and Zhejiang in China. We then compared physical performance differences between the normal-weight group and the overweight-obesity group.
Results: A smooth and effective standard deviation unit curve of WFH was established. The overweight and obesity of Chinese preschool children were at a high level. Being overweight and obese reduced preschool children's relative strength, speed, sensitivity, coordination, and balance ability, but did not reduce preschool children's flexibility. In general, the physical performance of preschool children in the normal weight group was better than that in the overweight and obesity group.
Conclusion: It is suggested to use the WFH criteria in this study to evaluate overweight and obesity in Chinese preschool children, and strengthen physical activity and take in energy substances properly of preschool children, to control the spread of overweight and obesity， to improve physical performance level.

Published: June 2023

Background & Objective: Prediction of preterm delivery can reduce a large number of its complications. The present study aimed to compare vaginal and plasma fibronectin concentrations in the diagnosis of preterm delivery.Materials & Methods: Serum samples were obtained from 105 women at 24-36 weeks of gestation. However, only 40 women gave permission to collect vaginal samples. Fibronectin concentration was measured using the ELISA technique. Then, plasma and vaginal fibronectin levels were compared in term and preterm deliveries.Results: The mean plasma fibronectin level was 6226.43±7174.97 ng/ml among the mothers with term infants and 7724.01±1143.82 ng/ml among those with preterm infants (p=0.667). The mean fetal fibronectin level was 156.61±126.42 ng/ml among the mothers with term infants and 127.71±43.14 ng/ml among those with preterm infants (p=0.241). The cut-off point of plasma fibronectin level was 1750 ng/ml with a sensitivity of 80.25% and specificity of 85.17%. Additionally, the cut-off point of vaginal fibronectin level was 158.98 ng/ml with a sensitivity of 94.62% and specificity of 22.08%.Conclusion: Plasma fibronectin analysis had lower sensitivity and higher specificity compared to vaginal fibronectin analysis. This implies that plasma testing has lower false-positive cases and can identify a more significant number of true positive cases of preterm delivery.

Published: June 2023

Background: Malnutrition has impacted the health condition and life quality of the elderly who live in nursing homes. Unmaximized menu planning can cause this condition.
Objectives: This study aimed to analyze the nutrition content of the menu provided by the nursing home based on recommended dietary allowance (RDA) for older people and to identify the current nutrition status of the elderly
Methods: The food intakes were evaluated by observing all menus during the five days. Nutrient contents were analyzed by calculating all meal nutrition and comparing them to the recommended dietary allowance for the elderly. Body weight was measured using Bio Impedance Analysis (BIA) Tanita, and a stadiometer measured body height. Furthermore, weight and high were measured based on body mass index calculation to measure nutritional status.
Results: It was found that the mean energy content was 1242.6 ± 193.9 kcal/day, and only 69.03 ± 10.7% fulfilled the recommendation. For protein content, it only met 70.5% of the RDA. Macronutrients such as protein are only 70.5% of the recommended dietary needs for the elderly. From BMI analysis, it was found that 26.23 % of the elderly are undernutrition.
Conclusions: The nutritional content of the menus served for the elderly in nursing homes did not yet meet the daily requirement and is still below that recommended for the elderly, so the nutrient of the menus should be increased to achieve optimum nutritional status.

Published: June 2023

Background:
Knee fracture-dislocations are complex injuries; however, there is no universally accepted definition of what constitutes a fracture-dislocation within the Schenck Knee Dislocation (KD) V subcategory. The purpose of this study was to establish a more precise definition for fracture patterns included within the Schenck KD V subcategory.

Methods:
A series of clinical scenarios encompassing various fracture patterns in association with a bicruciate knee ligament injury was created by a working group of 8 surgeons. Utilizing a modified Delphi technique, 46 surgeons from 18 countries and 6 continents with clinical and academic expertise in multiligamentous knee injuries undertook 3 rounds of online surveys to establish consensus. Consensus was defined as ≥70% agreement with responses of either “strongly agree” or “agree” for a positive consensus or “strongly disagree” or “disagree” for a negative consensus.

Results:
There was a 100% response rate for Rounds 1 and 2 and a 96% response rate for Round 3. A total of 11 fracture patterns reached consensus for inclusion: (1) nondisplaced articular fracture of the femur; (2) displaced articular fracture of the femur; (3) tibial plateau fracture involving the weight-bearing surface (with or without tibial spine involvement); (4) tibial plateau peripheral rim compression fracture; (5) posterolateral tibial plateau compression fracture, Bernholt type IIB; (6) posterolateral tibial plateau compression fracture, Bernholt type IIIA; (7) posterolateral tibial plateau compression fracture, Bernholt type IIIB; (8) Gerdy’s tubercle avulsion fracture with weight-bearing surface involvement; (9) displaced tibial tubercle fracture; (10) displaced patellar body fracture; and (11) displaced patellar inferior pole fracture. Fourteen fracture patterns reached consensus for exclusion from the definition. Two fracture patterns failed to reach consensus for either inclusion or exclusion from the definition.

Conclusions:
Using a modified Delphi technique, this study established consensus for specific fracture patterns to include within or exclude from the Schenck KD V subcategory.

Irreducible Tibial Pilon Fracture Treated with Single-Stage Closed Ilizarov Fixation and Gradual Correction
Authors: Gopalan Balachandar 
Published: June 2023

Case:
A young polytrauma victim of a road traffic accident was diagnosed with comminuted articular fracture of the left distal tibial pilon and open segmental fracture of the fibula. The comminuted distal tibial metaphysis was translocated into the interosseous space and, hence, was irreducible. He underwent single-stage closed Ilizarov device stabilization and gradual postoperative closed reduction to obtain good functional outcome at 9 months. The lung and scapular injuries were treated conservatively.

Conclusion:
Acute complex irreducible tibial pilon fracture can be treated according to principles of deformity correction with the Ilizarov device.
