RESUMO

Angiotensin-converting enzyme 2 (ACE-2) is the main cell entry receptor for severe acute respiratory syndrome-Coronavirus-2 (SARS-CoV-2), thus playing a critical role in causing Coronavirus disease 2019 (COVID-19). The role of smoking habit in the susceptibility to infection is still controversial. In this study we correlated lung ACE-2 gene expression with several clinical/pathological data to explore susceptibility to infection. This is a retrospective observational study on 29 consecutive COVID-19 autopsies. SARS-CoV-2 genome and ACE-2 mRNA expression were evaluated by real-time polymerase chain reaction in lung tissue samples and correlated with several data with focus on smoking habit. Smoking was less frequent in high than low ACE-2 expressors (p = 0.014). A Bayesian regression also including age, gender, hypertension, and virus quantity confirmed that smoking was the most probable risk factor associated with low ACE-2 expression in the model. A direct relation was found between viral quantity and ACE-2 expression (p = 0.028). Finally, high ACE-2 expressors more frequently showed a prevalent pattern of vascular injury than low expressors (p = 0.049). In conclusion, ACE-2 levels were decreased in the lung tissue of smokers with severe COVID-19 pneumonia. These results point out complex biological interactions between SARS-CoV-2 and ACE-2 particularly concerning the aspect of smoking habit and need larger prospective case series and translational studies.

RESUMO

BACKGROUND: Transmission within families and multiple spike protein mutations have been associated with the rapid transmission of SARS-CoV-2. We aimed to: (1) describe full genome characterization of SARS-CoV-2 and correlate the sequences with epidemiological data within family clusters, and (2) conduct phylogenetic analysis of all samples from Yogyakarta and Central Java, Indonesia and other countries. METHODS: The study involved 17 patients with COVID-19, including two family clusters. We determined the full-genome sequences of SARS-CoV-2 using the Illumina MiSeq next-generation sequencer. Phylogenetic analysis was performed using a dataset of 142 full-genomes of SARS-CoV-2 from different regions. RESULTS: Ninety-four SNPs were detected throughout the open reading frame (ORF) of SARS-CoV-2 samples with 58% (54/94) of the nucleic acid changes resulting in amino acid mutations. About 94% (16/17) of the virus samples showed D614G on spike protein and 56% of these (9/16) showed other various amino acid mutations on this protein, including L5F, V83L, V213A, W258R, Q677H, and N811I. The virus samples from family cluster-1 (n = 3) belong to the same clade GH, in which two were collected from deceased patients, and the other from the survived patient. All samples from this family cluster revealed a combination of spike protein mutations of D614G and V213A. Virus samples from family cluster-2 (n = 3) also belonged to the clade GH and showed other spike protein mutations of L5F alongside the D614G mutation. CONCLUSIONS: Our study is the first comprehensive report associating the full-genome sequences of SARS-CoV-2 with the epidemiological data within family clusters. Phylogenetic analysis revealed that the three viruses from family cluster-1 formed a monophyletic group, whereas viruses from family cluster-2 formed a polyphyletic group indicating there is the possibility of different sources of infection. This study highlights how the same spike protein mutations among members of the same family might show different disease outcomes.

RESUMO

BACKGROUND: Limb salvage surgery (LSS) is the preferred method for treatment of patients with sarcomas and to a greater extent also to patients with metastatic bone disease. The aim of the present study was to evaluate the adaptive remodeling of the periprosthetic cortical bone after insertion of a tumor prosthesis with cemented stem. METHODS: A prospective study of 21 patients (F/M = 12/9), mean age 55 years (range 15-81) with metastatic bone disease (n = 9), sarcomas (n = 8) or aggressive benign tumors (n = 4) who underwent bone resection due to a tumor, and reconstruction with a tumor-prosthesis (Zimmer® Segmental 130 mm straight fluted cemented stem with trabecular metal (TM) collars) in the proximal femur (n = 10), distal femur (n = 9) or proximal tibia (n = 2). Measurements of bone mineral density (BMD) (g/cm2) were done postoperatively and after 3, 6, and 12 months using dual-energy X-ray absorptiometry. BMD was measured in 4 regions of interest around the cemented stem and in one region of interest 1 cm proximal from the ankle joint of the affected limb and measurement of the contralateral ankle was used as reference. Repeated measures ANOVA and students paired t-test was used to evaluate BMD changes over time. RESULTS: At 1-year follow-up, BMD decreased compared to baseline in all four regions of interest with a statistically significant bone loss of 8-15%. The bone loss was most pronounced (14-15%) in the 2 regions of interest closest to the trabecular metal (TM) collar and lowest (8%) adjacent to the tip of the stem. CONCLUSION: After 1 year the decrease in bone mineral density of the ankle on the affected limb was 9% and the contralateral ankle was close to baseline, thus suggesting that the periprosthetic bone mineral density changes during follow-up, mainly are caused by stress shielding and immobilization. TRIAL REGISTRATION: The study was approved by the Scientific Ethical Committee of the Capital Region of Denmark (J. No. H-2-2014-105) and the Danish Data Protection Agency (J. No.: 2012-58-00004 ).

RESUMO

Objective: To investigate the correlation between clinical periodontal indexes of periodontitis and glomerular filtration rate (GFR) in a non-diabetic elderly population in four communities of Shijingshan, Beijing. Methods: This was a cross-sectional study. Questionnaires, blood biochemical examinations, and periodontal indexes were conducted in elderly people (35 to 84 years old) in four communities of Shijingshan, Beijing between May and July 2005. Non-diabetic patients with fasting blood glucose<6.1 mmol/L, postprandial blood glucose<7.8 mmol/L, and ≥ 10 remaining teeth were included. Patients with diabetes, fasting blood glucose ≥6.1 mmol/L or postprandial blood glucose ≥7.8 mmol/L, and total residual teeth less than 10 were excluded. A total of 362 study subjects met the inclusion criteria. The survey subjects were selected by convenient sampling method. The mean full-mouth probing depth (PD), bleeding index (BI), attachment loss (AL), and plaque index (PLI), as well as PD≥4 mm% (the number of sites with PD≥4 mm as a percentage of the total number of sites in full mouth), PD≥5 mm%, PD≥6 mm%, AL≥3 mm%, AL≥4 mm%, AL≥5 mm% and AL≥6 mm% were used for the analysis. Serum creatinine values was used to calculate GFR. GFR≥90 ml/(min·1.73 m2) was defined as normal group and GFR<90 ml/(min·1.73 m2) was defined as reduced group. Univariate analysis was conducted between two groups. Multivariate regression analysis was performed with GFR as dependent variable and adjusted for risk factors such as age, sex, smoking, waist-hip ratio and physical activity. Results: There were 164 subjects in the normal GFR group (45.3%) and 198 in the reduced GFR group (54.7%). Percentage of males in the reduced GFR group, 118 in total, accounting for 59.6%, were significantly higher than in the normal GFR group (73, 44.5%)(P=0.004). The median of age, uric acid, triglyceride, and waist-to-hip ratio (65 years, 323 mmol/L, 1.73 mmol/L, 0.90) were significantly higher in the reduced GFR group than in the normal GFR group (54 years, 277 mmol/L, 1.45 mmol/L, 0.88) (P<0.05). The median of PD mean, AL mean, BI mean, PD≥4 mm%, AL≥3 mm%, and AL≥4 mm% in the reduced GFR group were 2.80 mm, 2.52 mm, 2.06, 20.4%, 46.5%, and 30.4%, respectively, which were significantly higher than those in the GFR normal group (2.60 mm, 2.37 mm, 1.93, 16.6%, 42.9%, 28.9%) (P<0.05). After adjusting for confounding factors such as age, gender, smoking, waist-to-hip ratio and physical activity, the results of logistic regression analysis showed that PD mean, AL mean, PD≥4 mm%, PD≥5 mm%, PD≥6 mm%, AL≥3 mm% and AL≥4 mm% of clinical periodontal indexes were significantly correlated with reduced GFR in this population (OR values were 1.765, 1.879, 1.430, 1.713, 1.771, 1.428, 1.445, respectively, P<0.05). Conclusions: In the non-diabetic elderly population in communities of Shijingshan, Beijing, clinical periodontal indexes reflecting the degree of periodontal tissue destruction were associated with a decreased level of GFR.

RESUMO

Human T-lymphotropic virus type I (HTLV-I) is a retrovirus associated with adult T-cell lymphoma (ATL) and HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP). In addition to HAM/TSP and ATL, HTLV-I-associated encephalopathy and cerebellar involvement have been reported. We report a case of an 87-year-old Japanese woman presenting with progressive dysarthria and gait disturbance. Neurological examination showed word-finding difficulty, scanning speech, saccadic eye movements, ocular dysmetria, gaze-evoked nystagmus and bilateral dysmetria. There was no motor weakness or spasticity. HTLV-I antibody was detected in both her serum and cerebrospinal fluid. Cerebrospinal fluid neopterin (57 pg/mL) and IgG index (3.27) were significantly elevated. MRI showed cerebellar swelling. She was finally diagnosed with HTLV-I associated cerebellitis. Two courses of high-dose intravenous methylpredonine therapy attenuated cerebellar ataxia and cerebellar swelling. It suggests that cerebellitis can result from HTLV-I infection, regardless of the existence of ATL or HAM/TSP.

RESUMO

An 85-year-old man with a known history of abdominal aortic aneurysm (AAA) presented to a vascular surgery clinic with a severely swollen, tender and erythematous left leg. An urgent CT angiogram demonstrated a left-sided, proximal deep vein thrombosis, and a permanent, Bird's Nest inferior vena cava (IVC) filter (Cook, Inc., Bloomington, Ind.) penetrating his AAA. The patient was treated with a course of apixaban 5 mg two times per day and the decision was made to closely observe his IVC filter and AAA, given his numerous comorbidities and age. This case highlights the unique considerations associated with an approach to permanent IVC filter complications among patients with AAAs.

RESUMO

The diagnosis of elderly-onset IgA vasculitis (IgAV) and its prognosis can be difficult to ascertain because of its rarity and the frequent presence of comorbidities. Furthermore, the treatment of elderly-onset IgAV remains controversial. We report a case of IgAV in an 87-year-old patient. Renal involvement was detected early during the IgAV follow-up. He was treated with low-dose corticosteroid and azathioprine, which led to a complete remission without any adverse effects. This suggests that precise intervention with early diagnosis and careful renal follow-up may prevent renal failure and that low-dose steroids with azathioprine can be an effective treatment for elderly-onset IgAV with nephritis.

RESUMO

CONTEXT: Calcifediol has been proposed as a potential treatment for COVID-19 patients. OBJECTIVE: To compare the administration or not of oral calcifediol on mortality risk of patients hospitalized because of COVID-19. DESIGN: Retrospective, multicenter, open, non-randomized cohort study. SETTINGS: Hospitalized care. PATIENTS: Patients with laboratory-confirmed COVID-19 between 5 February and 5 May 2020 in five hospitals in the South of Spain. INTERVENTION: Patients received calcifediol (25-hydroxyvitamin D3) treatment (0.266 mg/capsule, 2 capsules on entry and then one capsule on day 3, 7, 14, 21, and 28) or not. MAIN OUTCOME MEASURE: In-hospital mortality during the first 30 days after admission. RESULTS: A total of 537 patients were hospitalized with COVID-19 (317 males (59%), median age, 70 years), and 79 (14.7%) received calcifediol treatment. Overall, in-hospital mortality during the first 30 days was 17.5%. The OR of death for patients receiving calcifediol (mortality rate of 5%) was 0.22 (95% CI, 0.08 to 0.61) compared to patients not receiving such treatment (mortality rate of 20%; p < 0.01). Patients who received calcifediol after admission were more likely than those not receiving treatment to have comorbidity and a lower rate of CURB-65 score for pneumonia severity ≥ 3 (one point for each of confusion, urea > 7 mmol/L, respiratory rate ≥ 30/min, systolic blood pressure < 90 mm Hg or diastolic blood pressure ≤ 60 mm Hg, and age ≥ 65 years), acute respiratory distress syndrome (moderate or severe), c-reactive protein, chronic kidney disease, and blood urea nitrogen. In a multivariable logistic regression model, adjusting for confounders, there were significant differences in mortality for patients receiving calcifediol compared with patients not receiving it (OR = 0.16 (95% CI 0.03 to 0.80). CONCLUSION: Among patients hospitalized with COVID-19, treatment with calcifediol, compared with those not receiving calcifediol, was significantly associated with lower in-hospital mortality during the first 30 days. The observational design and sample size may limit the interpretation of these findings.

RESUMO

The trace element copper (Cu) is part of our nutrition and essentially needed for several cuproenzymes that control redox status and support the immune system. In blood, the ferroxidase ceruloplasmin (CP) accounts for the majority of circulating Cu and serves as transport protein. Both Cu and CP behave as positive, whereas serum selenium (Se) and its transporter selenoprotein P (SELENOP) behave as negative acute phase reactants. In view that coronavirus disease (COVID-19) causes systemic inflammation, we hypothesized that biomarkers of Cu and Se status are regulated inversely, in relation to disease severity and mortality risk. Serum samples from COVID-19 patients were analysed for Cu by total reflection X-ray fluorescence and CP was quantified by a validated sandwich ELISA. The two Cu biomarkers correlated positively in serum from patients with COVID-19 (R = 0.42, p < 0.001). Surviving patients showed higher mean serum Cu and CP concentrations in comparison to non-survivors ([mean+/-SEM], Cu; 1475.9+/-22.7 vs. 1317.9+/-43.9 µg/L; p < 0.001, CP; 547.2.5 +/- 19.5 vs. 438.8+/-32.9 mg/L, p = 0.086). In contrast to expectations, total serum Cu and Se concentrations displayed a positive linear correlation in the patient samples analysed (R = 0.23, p = 0.003). Serum CP and SELENOP levels were not interrelated. Applying receiver operating characteristics (ROC) curve analysis, the combination of Cu and SELENOP with age outperformed other combinations of parameters for predicting risk of death, yielding an AUC of 95.0%. We conclude that the alterations in serum biomarkers of Cu and Se status in COVID-19 are not compatible with a simple acute phase response, and that serum Cu and SELENOP levels contribute to a good prediction of survival. Adjuvant supplementation in patients with diagnostically proven deficits in Cu or Se may positively influence disease course, as both increase in survivors and are of crucial importance for the immune response and antioxidative defence systems.

RESUMO

Nearly 5% of patients suffering from COVID-19 develop acute respiratory distress syndrome (ARDS). Extravascular lung water index (EVLWI) is a marker of pulmonary oedema which is associated with mortality in ARDS. In this study, we evaluate whether EVLWI is higher in patients with COVID-19 associated ARDS as compared to COVID-19 negative, ventilated patients with ARDS and whether EVLWI has the potential to monitor disease progression. EVLWI and cardiac function were monitored by transpulmonary thermodilution in 25 patients with COVID-19 ARDS subsequent to intubation and compared to a control group of 49 non-COVID-19 ARDS patients. At intubation, EVLWI was noticeably elevated and significantly higher in COVID-19 patients than in the control group (17 (11-38) vs. 11 (6-26) mL/kg; p < 0.001). High pulmonary vascular permeability index values (2.9 (1.0-5.2) versus 1.9 (1.0-5.2); p = 0.003) suggested a non-cardiogenic pulmonary oedema. By contrast, the cardiac parameters SVI, GEF and GEDVI were comparable in both cohorts. High EVLWI values were associated with viral persistence, prolonged intensive care treatment and in-hospital mortality (23.2 ± 6.7% vs. 30.3 ± 6.0%, p = 0.025). Also, EVLWI showed a significant between-subjects (r = - 0.60; p = 0.001) and within-subjects correlation (r = - 0.27; p = 0.028) to Horowitz index. Compared to non COVID-19 ARDS, COVID-19 results in markedly elevated EVLWI-values in patients with ARDS. High EVLWI reflects a non-cardiogenic pulmonary oedema in COVID-19 ARDS and could serve as parameter to monitor ARDS progression on ICU.

RESUMO

The first COVID-19 contagion wave caused unprecedented restraining measures worldwide. In Italy, a period of generalized lockdown involving home confinement of the entire population was imposed for almost two months (9 March-3 May 2020). The present is the most extensive investigation aimed to unravel the demographic, psychological, chronobiological, and work-related predictors of sleep disturbances throughout the pandemic emergency. A total of 13,989 Italians completed a web-based survey during the confinement period (25 March-3 May). We collected demographic and lockdown-related work changes information, and we evaluated sleep quality, insomnia and depression symptoms, chronotype, perceived stress, and anxiety using validated questionnaires. The majority of the respondents reported a negative impact of confinement on their sleep and a delayed sleep phase. We highlighted an alarming prevalence of sleep disturbances during the lockdown. Main predictors of sleep disturbances identified by regression models were: female gender, advanced age, being a healthcare worker, living in southern Italy, confinement duration, and a higher level of depression, stress, and anxiety. The evening chronotype emerged as a vulnerability factor, while morning-type individuals showed a lower predisposition to sleep and psychological problems. Finally, working from home was associated with less severe sleep disturbances. Besides confirming the role of specific demographic and psychological factors in developing sleep disorders during the COVID-19 pandemic, we propose that circadian typologies could react differently to a particular period of reduced social jetlag. Moreover, our results suggest that working from home could play a protective role against the development of sleep disturbances during the current pandemic emergency.

RESUMO

BACKGROUND: Although the incidence of symptomatic pulmonary thromboembolism after elective surgery for degenerative musculoskeletal disorders is comparatively low, it is extremely detrimental to both patients and health-care providers. Therefore, its prevention is mandatory. We aimed to perform a cross-sectional analysis of deep venous thrombosis (DVT) before elective surgery for degenerative musculoskeletal disorders, including total knee arthroplasty (TKA), total hip arthroplasty (THA), and spinal surgery, and identify the factors associated with the incidence of preoperative DVT. METHODS: The clinical data of patients aged ≥ 30 years who underwent TKA or THA, and spine surgery for lumbar or cervical degenerative disorders at our institution were retrospectively collected. D-dimer levels were measured preoperatively in all the patients scheduled for surgery. For the patients with D-dimer levels ≥ 1 µg/mL or who were determined by their physicians to be at high risk of DVT, the lower extremity vein was preoperatively examined for DVT on ultrasonography. RESULTS: Overall, we retrospectively evaluated 1236 consecutive patients, including 701 men and 535 women. Of the patients, 431 and 805 had D-dimer levels ≥ 1 and < 1 µg/mL, respectively. Of 683 patients who underwent lower extremity ultrasonography, 92 had proximal (n = 7) and distal types (n = 85) of DVT. The preoperative prevalence of DVT was 7.4 %. No patient had the incidence of postoperative symptomatic venous thromboembolism. A multivariate analysis revealed that age ≥ 80 years (odds ratio [OR], 95 % confidence interval [CI]: 2.8, 1.1-7.3), knee surgery (2.1, 1.1-4.0), American Society of Anesthesiologists (ASA) grade 2 (2.8, 1.2-6.8), ASA grades 3 or 4 (3.1, 1.0-9.4), and malignancy (1.9, 1.1-3.2) were significantly associated with DVT incidence. CONCLUSIONS: This is the first study to conduct a cross-sectional analysis of preoperative DVT data of patients scheduled for elective surgery for degenerative musculoskeletal disorders. Although whether screening for preoperative DVT is needed to prevent postoperative symptomatic pulmonary thromboembolism remains to be clarified, our data suggested that DVT should be noted before surgery in the patients with advanced age, knee surgery, high ASA physical status, and malignancy.

RESUMO

BACKGROUND Whipple's triad is a rare condition that prompts urgent investigation. A rare cause of such a clinical presentation is excess production of insulin-like growth factor 2 (IGF-2) from a solitary fibrous tumor. CASE REPORT A 94-year-old man presented to the hospital following episodes of confusion, gait disturbance, and multiple falls secondary to hypoglycemia. His initial blood glucose was 45 mg/dL, with normalization to 144 mg/dL after administration of 1 ampule of glucose in the field. By the time the patient arrived at our facility, his blood glucose had fallen to 75 mg/dL, and then fell further to 38 mg/dL. He had no preceding history of hypoglycemia and led an active lifestyle. His medical history was relatively unremarkable with the exception of a large but asymptomatic solitary fibrous tumor previously diagnosed, being managed conservatively. A physical examination demonstrated a large, left-sided, nontender abdominal tumor. Computed tomography demonstrated a very large well-defined, complex mass in the left upper quadrant of the abdomen. Hypoglycemic episodes occurred frequently, and reliably ensued with fasting. Hypoglycemia proved refractory to conservative strategies, and surgical intervention was recommended. Despite challenges due to the tumor's characteristics, the mass was successfully resected and normoglycemia was achieved within 24 hours. CONCLUSIONS Solitary fibrous tumors may rarely present with hypoglycemia refractory to medical therapy. We present the first reported case of a nonagenarian patient with hypoglycemia secondary to ectopic production of IGF-2 from a solitary fibrous tumor managed with surgical resection.

RESUMO

Background: Adaptive immune responses to structural proteins of the virion play a crucial role in protection against coronavirus disease 2019 (COVID-19). We therefore studied T cell responses against multiple SARS-CoV-2 structural proteins in a large cohort using a simple, fast, and high-throughput approach. Methods: An automated interferon gamma release assay (IGRA) for the Nucleocapsid (NC)-, Membrane (M)-, Spike-C-terminus (SCT)-, and N-terminus-protein (SNT)-specific T cell responses was performed using fresh whole blood from study subjects with convalescent, confirmed COVID-19 (n = 177, more than 200 days post infection), exposed household members (n = 145), and unexposed controls (n = 85). SARS-CoV-2-specific antibodies were assessed using Elecsys® Anti-SARS-CoV-2 (Ro-N-Ig) and Anti-SARS-CoV-2-ELISA (IgG) (EI-S1-IgG). Results: 156 of 177 (88%) previously PCR confirmed cases were still positive by Ro-N-Ig more than 200 days after infection. In T cells, most frequently the M-protein was targeted by 88% seropositive, PCR confirmed cases, followed by SCT (85%), NC (82%), and SNT (73%), whereas each of these antigens was recognized by less than 14% of non-exposed control subjects. Broad targeting of these structural virion proteins was characteristic of convalescent SARS-CoV-2 infection; 68% of all seropositive individuals targeted all four tested antigens. Indeed, anti-NC antibody titer correlated loosely, but significantly with the magnitude and breadth of the SARS-CoV-2-specific T cell response. Age, sex, and body mass index were comparable between the different groups. Conclusion: SARS-CoV-2 seropositivity correlates with broad T cell reactivity of the structural virus proteins at 200 days after infection and beyond. The SARS-CoV-2-IGRA can facilitate large scale determination of SARS-CoV-2-specific T cell responses with high accuracy against multiple targets.

RESUMO

BACKGROUND: Older persons with polypharmacy are at increased risk of harm from medications. Therefore, it is important that physicians and nurses, together with the persons, evaluate medications to avoid hazardous polypharmacy. It remains unclear how healthcare professionals experience such evaluations. This study aimed to explore physicians' and nurses' experiences from evaluations of older persons' medications, and their related actions to manage concerns related to the evaluations. METHOD: Individual interview data from 29 physicians and nurses were collected and analysed according to the critical incident technique. RESULTS: The medication evaluation for older persons was influenced by the working conditions (e.g. healthcare professionals' clinical knowledge, experiences, and situational conditions) and working in partnership (e.g. cooperating around and with the older person). Actions taken to manage these evaluations were related to working with a plan (e.g. performing day-to-day work and planning for continued treatment) and collaborative problem-solving (e.g. finding a solution, involving the older person, and communicating with colleagues). CONCLUSION: Working conditions and cooperation with colleagues, the older persons and their formal or informal caregivers, emerged as important factors related to the medication evaluation. By adjusting their performance to variations in these conditions, healthcare professionals contributed to the resilience of the healthcare system by its capacity to prevent, notice and mitigate medication problems. Based on these findings, we hypothesize that a joint plan for continued treatment could facilitate such resilience, if it articulates what to observe, when to act, who should act and what actions to take in case of deviations from what is expected.

RESUMO

Objective: To examine the outcome of endovascular treatment in patients of isolated abdominal aortic dissection. Methods: From February 2012 to June 2020, 61 patients (44 males, 17 females) with an age of (60.2±11.4) years (range: 43 to 87 years) of isolated abdominal aortic dissection who underwent the endovascular treatment, including bifurcated and straight aortic stent graft, in the Department of Vascular Surgery, the Second Xiangya Hospital, Central South University were enrolled. There were 47 patients treated with bifurcated aortic stent grafts and 14 patients with straight aortic stent grafts. Patient demographic, preoperative, intraoperative, perioperative data were collected. Clinical follow-up data, including mortality, relative complications and aortic remodeling, were obtained. Kaplan-Meier method and Log-rank test was used to calculate and compare the rates of survival and freedom from all adverse events. Results: The operative time was (142.4±47.9) minutes (range:70 to 310 minutes) and (95.7±23.7) minutes (range: 70 to 150 minutes) in bifurcated stent group and straight stent group, respectively. The perioperative mortality was 0. One patient had partial occlusion of the left renal artery, and 3 patients had type Ⅰa endoleak post-operation. The follow-up period was (37.1±22.1) months (range: 3 to 91 months). Three patents suffered from type B aortic dissection; one of them progressed into type A aortic dissection and died, another one was treated with secondary endovascular operation, and the remaining one was treated conservatively. One patient had type A aortic dissection and was treated conservatively for 57 months without any discomfort. Stent grafts in iliac artery occlusion happened in 2 patients treated with a bifurcated graft, one of them was treated with a secondary operation because of severe symptom. Aortic remodeling was well with the treatment of bifurcated and straight grafts. There was no difference in the cumulative survival (P=0.584) and freedom from all adverse events (P=0.309) between the two different endovascular treatment strategies. Conclusion: Endovascular aortic repair is an effective and safe treatment strategy for isolated abdominal aortic dissection with reliable mid-term result and excellent aortic remodeling.

RESUMO

Objective: To examine a new technique of robot-assisted nephroureterectomy without robot reldocking or patient repositioning. Methods: Patients diagnosed as upper tract urothelial carcinoma treated with this modality between November 2015 and January 2019 at Department of Urology, Sir Run Run Shaw Hospital, Zhejiang University School of Medicine were included in this analysis. Data collection including patient demographics, operative procedure and postoperative morbidities were conducted by retrospective charts review, after receiving the institutional review board's approval. There were 35 males and 27 females with a median age of 70 years (range: 30 to 91 years) underwent single docking robot-assisted nephroureterectomy without repositioning. Among the 62 cases, 37 patients had pelvic carcinoma while 25 patients had ureteral carcinoma (with proximal portion 12 cases, middle portion 5 cases and distal portion 8 cases). The patient was placed in a 60 to 80-degree, modified flank position with a 15-degree Trendelenburg tilt. The contralateral arm was positioned perpendicular to the torso on an arm board while the ipsilateral arm was taped to the patient's side with ample padding. The robot cart was then docked at a 90-degree angle, perpendicular to the patient. A "W"-shape, three robotic-arm configurations was used for port placement. Results: The surgical procedures were performed successfully in all the 62 patients. The operation time was (171.6±54.7) minutes (range: 60 to 370 minutes). The estimated blood loss during the operation was 50(50) ml (range: 20 to 400 ml) with 4 patients had transfusion. No perioperative death was encountered. Eleven patients had post-operative complications (Clavien-Dindo grade 2) including 3 cases of hemorrhage and 8 cases of chylous leakage. All cases were regularly followed up with a median time of 37 months (range: 17 to 55 months). There were 8, 30, 19, 4 and 1 case followed up for 48, 36, 24, 18 and less than 18 months, respectively. Three patients had reginal recurrences and 11 cases of distant metastasis occurred, with 5 patients died for cancer. The survival rate within 24 months was estimated as 75.4%(43/57). Conclusion: Robot-assisted nephroureterectomy without robot redocking or patient repositioning could be safely reproduced, with surgical outcomes comparable to other established techniques.

RESUMO

The aim of the study was to evaluate the effectiveness of the global coagulation test of thrombodynamics for monitoring and correcting the hemostatic system and improving the results of complex treatment in patients with SARS-CoV-2 in the COVID hospital. From April 2020 to December 2020 on the basis of the University Clinical Hospital No. 4 of the First Moscow State Medical University named I.M. Sechenov (Sechenov University) of the Ministry of Health of the Russian Federation 245 patients between the ages of 27 and 89 with SARS-CoV-2 associated pneumonia were treated. The mean age of the patients was 56.7 ± 4.2 years. All patients participating in the study were divided by simple randomization into two groups. The volume of lesion of the lung parenchyma was assessed according to the data of computed tomography. All patients were treated for SARS-CoV-2 in a comprehensive manner in accordance with the temporary guidelines of the Ministry of Health of the Russian Federation with the mandatory prescription of low molecular weight heparins (LMWH). Assessment and correction of the hemostasis system in 177 patients (47.7%) of group 1 was carried out daily using local coagulation tests (LCT), including APTT, PT, TT, PTI, INR, Fibrinogen and D-dimer level. The second group included 128 patients (52.3%), who, in addition to local coagulation tests, used the integral coagulation test - the thrombodynamics test- to assess and correct the state of the hemostatic system. Assessment and correction of hemostasis were performed at the control points (1, 7, 14 days) of the study. Compared to LCT, the thrombodynamics test reliably more often revealed the state of hypercoagulability, which was promptly corrected by increased doses of LMWH in group 2. Positive dynamics of clinical symptoms were detected in patients of group 2 1.8 times more often than in group 1 (p<0.05): fever and shortness of breath in group 2 decreased faster, the SpO2 index recovered more rapidly, especially in patients with severe hypoxia (with SpO2<90), the number of patients with moderate and severe severity by the third point of the study in group 2 was 1.8 times less than in group 1 (p<0.05). Severe forms of lung damage (CT-3 and CT-4) were detected in group 2 3.2 times less frequently (p <0.01) compared with group 1, and the number of deaths was 3.3 times less frequent (p<0.01) by the end of the study. The average bed-day in group 2 of patients (15±1.6 days) was 1.6 times shorter than in group 1 (24±7.2 days). Hemorrhagic complications were not recorded, despite the therapeutic doses of LMWH in patients of group 2. The severity of the condition of patients with SARS-CoV-2 and the dynamics of their symptoms depend on the state of microcirculation in the lungs and in the periphery and on the volume of thrombotic lesions. Anticoagulant therapy prescribed as early as possible in adequate therapeutic doses in patients with SARS-CoV-2 associated viral pneumonia made it possible to achieve positive treatment results. The use of the global coagulation thrombodynamics test has shown high efficiency for the timely assessment and correction of the state of the hemostasis system.
