Authors: Silva Thaiane Almeida , Portella Patricia Cardoso , Figueiredo Karla Crozeta , Wolff Lillian Daisy Gonçalves , Lima Eliane de Fátima Almeida 
Published: April 2021

Objetivo: Identificar na literatura estudos que utilizaram o questionário Patient Safety Climate in Healthcare Organizations (PSCHO) na avaliação do clima de segurança do paciente em serviços de saúde hospitalares. Método: Trata-se de uma revisão integrativa da literatura, definida como pesquisa concisa em área específica. A busca e seleção dos estudos foi realizada por duas revisoras, de forma independente nas bases de dados LILACS, MEDLINE, CINAHL e WoS. Os resultados foram apresentados por meio do fluxograma PRISMA. Resultados: Foram recuperados na busca seis artigos, dos quais quatro foram incluídos e analisados. Os estudos foram realizados na China e nos Estados Unidos e as dimensões “medo de culpabilização e punição” e “medo da vergonha” sobressaíram de forma negativa nos estudos chineses. O PSCHO apresentou similaridades quando comparado a outros estudos que avaliaram o clima de segurança do paciente utilizando outros questionários de clima. Conclusão: Os resultados demonstraram que o PSCHO é útil para avaliar o clima de segurança do paciente. A ausência de estudos brasileiros utilizando o questionário indica uma potencialidade de sua aplicação em novas pesquisas, como estratégia para a melhoria da qualidade e promoção da segurança do paciente nas Organizações de Saúde.

Published: April 2021

In order to determine the clinical significance of exercise stress echocardiography in patients with severe to moderate aortic stenosis, a stress-induced increase in the mean pressure gradient across the aortic valve was recorded and myocardial contractile reserve was assessed using a number of parameters (ejection fraction, global longitudinal strain, elasticity index). It was found that, with normal values of EF at rest in patients with severe and moderate aortic stenosis, the deficit in contractile function was revealed using the GLS index, which demonstrated a decrease in both groups at the peak of exercise. A decrease in contractile reserve by both parameters (EF and GLS) was found in the group of patients with severe AS, which, combined with a significant stress-induced increase in the gradient on the aortic valve (≥18–20 mm Hg), an increase in pulmonary artery pressure (> 60 mm Hg) and decrease in systemic systolic blood pressure (>20 mm Hg) should be considered as a predictors of a poor prognosis of the natural course of aortic valve disease, and patients with similar stress test results should be possible candidates for surgical aortic valve replacement. A decrease in the in the LV elasticity index augmentation at the peak of exercise, strongly correlated with changes in other considered parameters of contractility and the metabolic power of exercise (MET), significantly complements the functional characteristics of the lesion for choosing the optimal management strategy. Consequently, exercise stress echocardiography is an indispensable diagnostic tool for determining the prognosis and timing of surgery in patients with aortic stenosis.

Authors: Maksimova M. S. 
Published: April 2021

Aim. Study electrocardiographic (ECG) and vectorcardiographic (VCG) indicators for various types of structural- geometric remodeling of the left ventricle (LV) in patients with arterial hypertension (AH).Material and research methods. The analysis was performed in 336 people, including 264 patients with AH, mean age 61.02 ± 7.61 years and 72 practically healthy individuals (57.18 ± 6.47). The ECG indicators of heart rate and duration of P, QRS, RR, PQ, QT, QT corrected according to the Bazett, Friderici and Sagie formulas (QTCB, QTCF, QTCS) were assessed. Echocardiography was used to calculate myocardial mass (LVMM) and LVMM index (LVMI), relative wall thickness (RWT). In the own plane of the VCG: the area of the QRS loop (SQRS), the magnitude of the geometric vector (maxQRS) were determined.Results. Correlation analysis showed the presence of a positive relationship between LVM and LVMI with SQRS (r = 0.49 and r = 0.38), maxQRS (r = 0.28 and r=0.33) and with QRS duration (r = 0.50 and r = 0.43). The groups of patients with concentric (CG) and eccentric (EH) hypertrophy in comparison with controls and patients with AH without LVH gave significantly higher values of absolute QT, QTCF, QTCS. There was a positive correlation between QT and QTС with LVMM, LVMI and no relationship with RWT.Conclusions. In LVH, the duration of QRS and SQRS in its own plane increased. The highest SQRS values were observed in patients with CG of the left ventricle in comparison with EG. Patients with CG and EG did not differ in QRS duration. In patients with AH and LVH, the duration of absolute and corrected values of the QT interval was significantly longer than in patients without LVH. The QT interval lengthened with an increase in LVMM and LVMI. QT duration did not depend on the type of LV hypertrophy — concentric or eccentric.

Interpretation of bronchodilator (BD) test based on reaction of forced expiratory in one second (FEV 1). For assessing bronchodilator responsiveness of lung volumes, airway resistance remains largely unexplored. Therefore, we assessed the response of pulmonary function parameters to BD to reveal the most responsive parameter. 90 patients with chronic airway obstruction (61 male and 29 female; aged 55±11; post- BD FEV 1 was 63.1+18.3 % predicted) performed spirometry and static lung volume measurements before and after inhalation of BD. We calculated effect size (ES) for each parameter from the difference between two means divided by the standard deviation of baseline score. There was a significant increase both FVC and FEV 1by 8.2 and 12.3 % from baseline (p<0.001). ES were 0.34 for FEV1 and 0.26 for FVC. The ES for lung volumes were from -0.07 (total lung capacity) to -0.31 (residual volume). The ES for sRtot (specific airway resistance) was -0.5 and ES for sGeff (specific effective airway conductance) was 0.95. The parameters of airway resistance and conductance were more responsive for the assessment of pulmonary function changes than spirometry and lung volumes parameters in patients with chronic airway obstruction.

A new coronavirus COVID-19 has led to the development of a global pandemic. It is characterized by a high risk of developing pneumonia and multiple organ failure along with its capability to influence the central nervous system. The main methods of instrumental assessment of the functional state of the brain are electroencephalography (EEG) and somatosensory evoked potentials (SEPs), which have been routinely used with patients in critical care units.We recorded the EEGs and short-latency SEPs of 31 COVID-19 patients, all were treated at the N. V. Sklifosovsky Research Institute of Emergency Care in 2020. The combined data was used to analyse the following outcome.We detected abnormal EEGs in 23 COVID-19 patients (74 %). Seven (30.4 %) patients showed EEGs consisting of diffuse non-specific slowing, 4 patients had lateralized hemispheric slowing (17.4 %) and one patient (4,3 %) had frontal intermittent delta activity (FIRDA). Three (13 %) patients in comas had “burst-suppression» pattern, three (13 %) had isoelectric EEGs and two (8,7 %) had areactive alpha rhythm, regarded as an electrographic manifestation of alpha coma. Two patients had evidence of epileptiform discharges (9 %), triphasic waves were presented in one patient (4.3 %).EEG and SEPs with the median nerve stimulation in COVID-19 patients do not reveal specific changes, nevertheless they are informative instrumental methods for assessing the functional state of the brain to identify biomarkers of epileptic seizures and to prognosticate survival and recovery in comatose patients.

PurposeTo construct a proper model to screen for diabetic retinopathy (DR) with the RETeval.MethodThis was a cross-sectional study. Two hundred thirty-two diabetic patients and seventy controls were recruited. The DR risk assessment protocol was performed to obtain subjects’ DR risk score using the RETeval. Afterwards, the receiver operating characteristic (ROC) curve was used to determine the best cutoff for diagnosing DR. Random forest and decision tree models were constructed.ResultsWith increasing DR severity, the DR score gradually increased. When the DR score was used to diagnose DR, the ROC curve had an area under the curve of 0.881 (95% confidence interval: 0.836-0.927, P &lt; 0.001), with a best cutoff value of 22.95, a sensitivity of 74.3% (95 CI: 66.0%~82.6%), and a specificity of 90.6% (95 CI: 83.7% ~94.8%). The top four risk factors selected by the random forest were used to construct the decision tree for diagnosing DR, which had a sensitivity of 93.3% (95% CI: 86.3%~97.0%) and a specificity of 80.3% (95% CI: 72.1% ~86.6%).ConclusionsThe DR risk assessment protocol combined with the decision tree model was innovatively used to evaluate the risk of DR, improving the sensitivity of diagnosis, which makes this method more suitable than the current protocol for DR screening.

Published: April 2021

ObjectivesTo analyze the diagnostic benefit of fine needle aspiration biopsy cytology (FNAB-C) and core needle biopsy tissue (CNB-T) with the addition of thyroglobulin (Tg) in the washout of the needle or BRAF V600E mutation assessment in assessing cervical lymph node metastasis (LNM) in papillary thyroid carcinoma.Materials and MethodsA total of 186 lymph nodes were punctured by fine or core needle. The diagnostic performance of FNAB-C and CNB-T with Tg in the washout or BRAF V600E mutation assessment was compared.ResultsThe optimal cutoff value of FNAB-Tg was 1.0 ng/ml, with an AUC of 0.976. The sensitivity and specificity of FNAB-C in predicting cervical LNM were 97.4% and 71.4%, respectively, and the addition of FNAB-Tg could contribute to a sensitivity of 100% and a specificity of 95%, but the introduction of BRAF V600E mutation assessment was associated with a decreased sensitivity of 96.3% and a decreased specificity of 50.0%. The FNAB-Tg level showed a comparable distribution in malignant lymph nodes with different TgAb statuses, serum TSH levels, and serum Tg levels. The sensitivity and specificity of CNB-T in predicting cervical LNM were 98.9% and 100%, respectively. The addition of CNB-Tg did not alter the diagnostic ability, but the introduction of BRAF V600E mutation assessment obtained the best performance, with a sensitivity of 100% and specificity of 100%.ConclusionThe sensitivity and specificity of FNAB-C could be increased if combined with FNAB-Tg. CNB-T alone could provide satisfactory diagnostic reliability.
Effect of Discontinuous Yielding on the Strain Hardening Behavior of Fine-Grained Twinning-Induced Plasticity Steel
Authors: Kang Singon , Jeong Sujin , Ahn Yeon-Sang 
Published: April 2021

The yielding of a high Mn twinning-induced plasticity steel was examined in three fine-grained specimens recrystallized at 700°C for 5 min with different cooling conditions. While the stress-strain curves of furnace-cooled and air-cooled specimens exhibit a stress drop at yielding, the drop was not observed in the water-quenched specimen. A simple analysis of the displacement data indicates the occurrence of localized deformation at the beginning of the plastic deformation in the three tensile specimens with different cooling conditions. The localized deformation of all three specimens was confirmed as Lüders strain by digital image correlation (DIC) analysis. Based on this observation, the role of yielding behavior on the strain hardening rate evolution at an early stage of the tensile deformation was discussed.

Published: April 2021

Background: Nucleic acid detection and CT scanning have been reported in COVID-19 diagnosis. Here, we aimed to investigate the clinical significance of IgM and IgG testing for the diagnosis of highly suspected COVID-19.Methods: A total of 63 patients with suspected COVID-19 were observed, 57 of whom were enrolled (24 males and 33 females). The selection was based on the diagnosis and treatment protocol for COVID-19 (trial Sixth Edition) released by the National Health Commission of the People's Republic of China. Patients were divided into positive and negative groups according to the first nucleic acid results from pharyngeal swab tests. Routine blood tests were detected on the second day after each patient was hospitalized. The remaining serum samples were used for detection of novel coronavirus-specific IgM/IgG antibodies.Results: The rate of COVID-19 nucleic acid positivity was 42.10%. The positive detection rates with a combination of IgM and IgG testing for patients with COVID-19 negative and positive nucleic acid test results were 72.73 and 87.50%, respectively.Conclusions: We report a rapid, simple, and accurate detection method for patients with suspected COVID-19 and for on-site screening for close contacts within the population. IgM and IgG antibody detection can identify COVID-19 after a negative nucleic acid test. Diagnostic accuracy of COVID-19 might be improved by nucleic acid testing in patients with a history of epidemic disease or with clinical symptoms, as well as CT scans when necessary, and serum-specific IgM and IgG antibody testing after the window period.

Published: April 2021

Background: Microalbuminuria is a well-characterized marker of kidney malfunction, both in diabetic and non-diabetic populations, and is used as a prognostic marker for cardiovascular morbidity and mortality. A few studies implied that it has the same value in kidney transplanted patients, but the information relies on spot or dipstick urine protein evaluations, rather than the gold standard of timed urine collection.Methods: We revisited a cohort of 286 kidney transplanted patients, several years after completing a meticulously timed urine collection and assessed the prevalence of major cardiovascular adverse events (MACE) in relation to albuminuria.Results: During a median follow up of 8.3 years (IQR 6.4–9.1) 144 outcome events occurred in 101 patients. By Kaplan-Meier analysis microalbuminuria was associated with increased rate of CV outcome or death (p = 0.03), and this was still significant after stratification according to propensity score quartiles (p = 0.048). Time dependent Cox proportional hazard analysis showed independent association between microalbuminuria and CV outcomes 2 years following microalbuminuria detection (HR 1.83, 95% CI 1.07–2.96).Conclusions: Two years after documenting microalbuminuria in kidney transplanted patients, their CVD risk was increased. There is need for primary prevention strategies in this population and future studies should address the topic.

Objective: Olfactory impairment (OI) refers to decreased (hyposmia) or absent (anosmia) ability to smell. We sought to estimate the prevalence and correlates of OI among rural-dwelling Chinese older adults.Methods: This population-based cross-sectional analysis included 4,514 participants (age ≥65 years; 56.7% women) from the Multidomain Interventions to Delay Dementia and Disability in Rural China (MIND-China). The 16-item Sniffin' Sticks identification test (SSIT) was used to assess olfactory function. Olfactory impairment was defined as the SSIT score ≤10, hyposmia as SSIT score of 8–10, and anosmia as SSIT score &lt;8. Multivariable logistic regression models were used to examine factors associated with OI.Results: The overall prevalence was 67.7% for OI, 35.3% for hyposmia, and 32.5% for anosmia. The prevalence increased with age for OI and anosmia, but not for hyposmia. The multivariable-adjusted odds ratio (OR) of OI was 2.10 (95% CI 1.69–2.61) for illiteracy and 1.41 (1.18–1.70) for elementary school (vs. middle school or above), 1.30 (1.01–1.67) for current smoking (vs. never smoking), 0.86 (0.74–0.99) for overweight and 0.73 (0.61–0.87) for obesity (vs. normal weight), 4.21 (2.23–7.94) for dementia, 1.68 (1.23–2.30) for head injury, and 1.44 (1.14–1.83) for sinonasal disease. Illiteracy in combination with either male sex or diabetes was significantly associated with an over two-fold increased OR of OI (p for interactions &lt;0.05).Conclusion: Olfactory impairment is highly prevalent that affects over two-thirds of rural-dwelling older adults in China. OI is correlated with illiteracy, current smoking, dementia, head injury, and sinonasal disease, but negatively associated with overweight or obesity. Olfactory impairment as a potential clinical marker of neurodegenerative disorders among older adults deserves further investigation.
