Antecedentes Pocos estudios han investigado el impacto del síndrome metabólico (SM) en la enfermedad por coronavirus 2019 (COVID-19). Describimos las características clínicas y el pronóstico de los pacientes con COVID-19 confirmados con SM durante la hospitalización y después del alta. Métodos Se incluyeron retrospectivamente 233 pacientes con COVID-19 de los hospitales de 8 ciudades de Jiangsu, China. Se describieron las características clínicas de los pacientes con COVID-19 y se analizaron los factores de riesgo de enfermedad grave mediante un análisis de regresión logística. Resultados Cuarenta y cinco (19,3%) de los 233 pacientes de COVID-19 tenían EM. La mediana de edad de los pacientes de COVID-19 con EM fue significativamente mayor que la de los pacientes sin EM (53,0 años frente a 46,0 años, P=0,004). No hubo diferencias significativas en cuanto a los síntomas clínicos, las imágenes de TC torácica anormales y los fármacos de tratamiento entre los dos grupos. Hubo más pacientes con EM que tuvieron enfermedades graves (33,3% frente a 6,4%, P

Background The clinical and virological course of patients with coronavirus disease 2019 (COVID-19) are lacking. We aimed to describe the clinical and virological characteristics of COVID-19 patients from 10 designated hospitals in 10 cities of Jiangsu province, China. The factors associated with the clearance of SARS-CoV-2 were investigated. Methods A total of 328 hospitalized patients with COVID-19 were retrospectively recruited. The epidemiological, clinical, laboratory, radiology and treatment data were collected. The associated factors of SARS-CoV-2 clearance were analyzed. Results The median duration of hospitalization was 16.0 days (interquartile range [IQR] 13.0–21.0 days). On multivariate Cox regression analysis, age > 60 years (hazard ratio [HR] 0.643, 95% confidence interval [CI] 0.454–0.911, P = 0.013) was associated with the delayed SARS-CoV-2 clearance, while the atomized inhalation of interferon α-2b could improve the clearance of SARS-CoV-2 (HR, 1.357, 95% CI 1.050–1.755, P = 0.020). Twenty-six (7.9%) patients developed respiratory failure and 4 (1.2%) patients developed ARDS. Twenty (6.1%) patients were admitted to the ICU, while no patient was deceased. Conclusions Our study found that age > 60 years was associated with the delayed SARS-CoV-2 clearance, while treated with atomized inhalation of interferon α-2b could promote the clearance of SARS-CoV-2.

We aimed to describe liver injury and identify the risk factors of liver injury in coronavirus disease (COVID-19) patients without chronic liver diseases (CLD). The clinical data of 228 confirmed COVID-19 patients without CLD were retrospectively collected from ten hospitals in Jiangsu, China. Sixty-seven (29.4%) of 228 patients without CLD showed abnormal liver function on admission, including increased alanine aminotransferase (ALT) (25 [11.0%]) U/L, aspartate aminotransferase (AST) 30 [13.2%]) U/L, gamma-glutamyl transferase (GGT) 28 [12.4%]) U/L, total bilirubin (Tbil) 16 [7.0%] µmol/L, and alkaline phosphatase (ALP) 10 [4.5%]) U/L. During hospitalization, 129 (56.3%) of 228 patients showed abnormal liver function, including elevated ALT (84 [36.8%]), AST (58 [25.4%]), GGT (67 [29.5%]), and Tbil (59 [25.9%]). Age over 50 years (odds ratio [OR], 2.086; 95% confidence interval [CI], 1.030-4.225; p = .041), male sex (OR, 2.737; 95% CI, 1.418-5.284; p = .003), and lopinavir-ritonavir (OR, 2.504; 95% CI, 1.187-5.283; p = .016) were associated with higher risk of liver function abnormality, while the atomized inhalation of interferon α-2b (OR, 0.256; 95% CI 0.126-0.520; p < .001) was associated with reduced risk of liver function abnormality during hospitalization. Mild to moderate liver injury was common in COVID-19 patients in Jiangsu, China. Age over 50 years, male sex, and lopinavir-ritonavir were the independent risk factors of liver impairment in COVID-19 patients during hospitalization.

Introduction: Nutritional status has been defined as an individual's health condition. The relationship between the progression of COVID-19 and Nutritional status is still unclear. We analyzed the clinical characteristics of 342 coronavirus disease 2019 (COVID-19) patients, and analyzed the relationship between the progression of COVID-19 and Nutritional status. Methodology: 342 COVID-19 were enrolled from ten different hospitals in China. The clinical characteristics were collected and analyzed. Results: The body mass index (BMI) of the mild patients (Group A) was higher than those in severe patients (Group B) and critical patients (Group C); The lactate dehydrogenase (LDH) level of Group A was lower than those of the other two groups; Sex, age, and BMI, was strongly correlated with Clinical classification (CT); Among the laboratory test results, Neutrophil (NEU%), Aspartate aminotransferase (AST), LDH, and blood glucose (BG) were positively correlated with CT; Lymphocyte ( LYM%), Platelet (PLT), Albumin (ALB), and Creatinine (Cr) were negatively correlated with CT. BMI, NEU%, LYM%, ALB, Cr, and PLT are all protective factors that affect CT. Conclusion: People with poor nutritional status (lower BMI and ALB) have a higher risk of developing severe disease after infection with SARS-CoV-2. In the clinical treatment of COVID-19, individualized nutritional support is very important for the rehabilitation of patients.

The impact of corticosteroid treatment on virological course of coronavirus disease 2019 (COVID-19) patients remains unclear. This study aimed to explore the association between corticosteroid and viral clearance in COVID-19. The clinical data of COVID-19 patients from 10 hospitals of Jiangsu, China, were retrospectively collected. Cox regression and Kaplan-Meier analysis were used to analyze the adverse factors of virus clearance. Of the 309 COVID-19 patients, eighty-nine (28.8%) patients received corticosteroid treatment during hospitalization. Corticosteroid group showed higher C-reactive protein (median 11.1 vs. 7.0 mg/l, P = 0.018) and lower lymphocytes (median 0.9 vs. 1.4 × 109/l, P

OBJECTIVE: This study aimed to observe the clinical characteristics of patients with coronavirus disease 2019 (COVID-19) with overweight and obesity. METHODS: Consecutive patients with COVID-19 from 10 hospitals of Jiangsu province, China, were enrolled. RESULTS: A total of 297 patients with COVID-19 were included, and 39.39% and 13.47% of patients had overweight and obesity, respectively. The proportions of bilateral pneumonia (92.50% vs. 73.57%, P = 0.033) and type 2 diabetes (17.50% vs. 3.57%, P = 0.006) were higher in patients with obesity than lean patients. The proportions of severe illness in patients with overweight (12.82% vs. 2.86%, P = 0.006) and obesity (25.00% vs. 2.86%, P < 0.001) were significantly higher than lean patients. More patients with obesity developed respiratory failure (20.00% vs. 2.86%, P < 0.001) and acute respiratory distress syndrome (5.00% vs. 0%, P = 0.024) than lean patients. The median days of hospitalization were longer in patients with obesity than lean patients (17.00 days vs. 14.00 days, P = 0.029). Overweight (OR, 4.222; 95% CI: 1.322-13.476; P = 0.015) and obesity (OR, 9.216; 95% CI: 2.581-32.903; P = 0.001) were independent risk factors of severe illness. Obesity (HR, 6.607; 95% CI: 1.955-22.329; P = 0.002) was an independent risk factor of respiratory failure. CONCLUSIONS: Overweight and obesity were independent risk factors of severe illness in COVID-19 patients. More attention should be paid to these patients.

Background. Chronic tinnitus affects approximately 10-15% of the population. Low-frequency repetitive transcranial magnetic stimulation (rTMS) has been considered as a promising and well-tolerated therapeutic strategy for chronic tinnitus. However, a recent large-scale multicenter clinical trial showed a negative result. Objective. This systematic review is aimed at assessing the efficacy and safety of low-frequency rTMS in chronic tinnitus. Methods. We searched PubMed, Embase, and Cochrane Library for randomized controlled studies of rTMS treatment of chronic tinnitus. A pooled analysis of standardized mean difference (SMD) was performed with 95% confidence intervals (CI). Results. Ten RCTs involving 567 participants were included in this review. Compared with sham stimulation, rTMS showed no significant efficacy in tinnitus severity and disability measured by Tinnitus Handicap Inventory (THI) in short-term (SMD=−0.04, 95% CI -0.23 to 0.16, P=0.72), medium-term (SMD=−0.13, 95% CI -0.43 to 0.17, P=0.41), and long-term (SMD=−0.16, 95% CI -0.38 to 0.05, P=0.14) follow-up. Tinnitus severity and disability measured by Tinnitus Questionnaire (TQ) also showed no significant improvement in short-term (SMD=−0.11, 95% CI -0.31 to 0.10, P=0.30), medium-term (SMD=−0.10, 95% CI -0.37 to 0.16, P=0.44), and long-term (SMD=−0.20, 95% CI -0.40 to 0.01, P=0.06) follow-up. Additionally, no statistically significant difference was shown in the changes of tinnitus loudness assessed by a visual analogue scale (VAS) between rTMS and sham groups in the short-term (SMD=−0.28, 95% CI -0.59 to 0.02, P=0.07), medium-term (SMD=−0.26, 95% CI -0.59 to 0.07, P=0.13), and long-term (SMD=−0.20, 95% CI -0.53 to 0.13, P=0.24) follow-up. Few mild or moderate adverse events were observed in both the rTMS and sham groups. Conclusion. Low-frequency rTMS is well tolerated but not effective in treating chronic tinnitus based on the current analysis of pooled data. Further studies with modified and uniform protocols are required to investigate the potential benefit of rTMS in chronic tinnitus.

Limited data are available for clinical characteristics of patients with coronavirus disease 2019 (COVID-19) outside Wuhan. This study aimed to describe the clinical characteristics of COVID-19 and identify the risk factors for severe illness of COVID-19 in Jiangsu province, China. Clinical data of hospitalized COVID-19 patients were retrospectively collected in 8 hospitals from 8 cities of Jiangsu province, China. Clinical findings of COVID-19 patients were described and risk factors for severe illness of COVID-19 were analyzed. By Feb 10, 2020, 202 hospitalized patients with COVID-19 were enrolled. The median age of patients was 44.0 years (interquartile range, 33.0–54.0). 55 (27.2%) patients had comorbidities. At the onset of illness, the common symptoms were fever (156 [77.2%]) and cough (120 [59.4%]). 66 (32.7%) patients had lymphopenia. 193 (95.5%) patients had abnormal radiological findings. 11 (5.4%) patients were admitted to the intensive care unit and none of the patients died. 23 (11.4%) patients had severe illness. Severe illness of COVID-19 was independently associated with body mass index (BMI) ≥ 28 kg/m2 (odds ratio [OR], 9.219; 95% confidence interval [CI], 2.731 to 31.126; P, Author summary We reported the epidemiology, clinical laboratory, radiological characteristics, treatment, and clinical outcomes of 202 confirmed cases of COVID-19 in 8 hospitals from 8 cities of Jiangsu province, China. In this case series in Jiangsu Province, COVID-19 patients had less severe symptoms and had better outcomes than the initial COVID-19 patients in Wuhan. The BMI ≥ 28 kg/m2 and a known history of type 2 diabetes were independent risk factors of severe illness in patients with COVID-19. Sustained intensive control efforts remain urgently needed to minimize the risk of COVID-19.

Cyclooxygenase-2 (COX-2) is known to be involved in the pathogenesis of migraine, and some polymorphisms are known to affect the expression of COX-2. This retrospective case-control study aimed to explore the associations between the -765 G>C (rs20417), -1759 G>A (rs3218625), and -8473 C>T (rs5275) COX-2 polymorphisms and migraine in Chinese Han individuals. One hundred and ten unrelated Han Chinese patients with migraine and 108 healthy controls were recruited between 03/2014 and 08/2016 at the First Affiliated Hospital of Nanjing Medical University and the First People's Hospital of Lianyungang City. The genotypes of all polymorphisms in controls followed the Hardy-Weinberg equilibrium (P = 0.215, P = 0.884, and P = 0.689). There were differences in the genotype and allele distributions of the COX-2-1759G>A (Gly587Arg) polymorphism between the migraine and control groups (P = 0.038 and P = 0.040, respectively). Compared with the COX-2-1759AG genotype, GG genotype carriers had an increased risk of migraine (odds ratio (OR) = 8.720, 95% confidence interval (CI): 1.072–70.960, P = 0.038). The frequency of the COX-2-1759A allele in patients with migraine was significantly lower than the controls (OR = 0.119, 95%CI: 0.015–0.957, P = 0.040). Adjusted age and sex, a statistical difference was found in the dominant model of COX-2-1759 G>A (OR = 0.118, 95% CI 0.014 to 0.962, P = 0.046). No significant difference was detected regarding the -765G>C and -8473T>C polymorphisms between the two groups. The COX-2 1759A allele might be involved in the development of migraine in Chinese Han individuals, but this will have to be confirmed in large-scale studies.

Background Several studies have demonstrated that repetitive transcranial magnetic stimulation (rTMS) may have a beneficial effect in Alzheimer’s disease (AD). Nevertheless, the clinical benefit of rTMS for AD remains inconclusive. Objective This systematic review and meta-analysis aimed to evaluate the efficacy and safety of rTMS in AD. Methods We searched PubMed, Embase and Cochrane for randomized controlled trials (RCTs) of rTMS for AD. We calculated pooled estimates of mean difference (MD) with 95% confidence intervals (CI). The protocol was registered at International Prospective Register of Systematic Reviews (PROSPERO) (number CRD42018089990). Results Five RCTs involving 148 participants were included in this review. Compared with sham stimulation, high-frequency rTMS led to a significant improvement in cognition as measured by ADAS-cog (MD = -3.65, 95% CI -5.82 to -1.48, p = 0.001), but not MMSE (MD = 0.49, 95% CI -1.45 to 2.42, p = 0.62). High-frequency rTMS also improved the global impression in comparison to the placebo (MD = -0.79, 95% CI -1.24 to -0.34, p = 0.0006). There was no significant difference in mood (MD = -1.36, 95% CI -3.93 to 1.21, p = 0.30) and functional performance (MD = 0.59, 95% CI -1.21 to 2.38, p = 0.52) between high-frequency rTMS and sham groups. Only one trial included low-frequency rTMS reported no significant improvement in cognition, mood and functional performance. Few mild adverse events were observed in both the rTMS and sham groups. Conclusions RTMS is relatively well tolerated, with some promise for cognitive improvement and global impression in patients with AD. Our findings also indicate the variability between ADAS-cog and MMSE in evaluating global cognitive impairment.

Peroxiredoxins, which reduced intracellular peroxides as a noval kind of antioxidant protein, were extensively expressed in various types of cancers and were thought as a biomarker of cancer cells. In this work, we performed genotyping analyses for tag SNP of Prdx 1, 2 and 6, and then evaluated the association with susceptibility and clinic stage of esophageal squamous cell carcinoma (ESCC) in a case–control study. The protein level of these Prdx isoforms in ESCC cancer samples was evaluated by Western blot. Then 356 ESCC cancer cases and 315 controls were genotyped by SNPshot assay. Differences in frequencies of the genotypes of the SNPs variant between the cases and controls were evaluated by using the chi-square test. Our result of Western blot confirmed the aberrant expression of Prdx 1, 2 and 6 in ESCC samples, which was coincident with other studies. After genotyping by SNPshot assay, the result showed that the allele and genotype frequencies did not differ between the patients and controls. And no association between the polymorphism and the progression of ESCC including tumor grade and stage was found. Our data suggested that polymorphisms of Prdx 1, 2 and 6 were not associated with esophageal cancer.
