End-stage renal disease (ESRD) patients undergoing outpatient hemodialysis (HD) and home peritoneal dialysis (PD) are high risk population of severe and critical types caused by SARS-CoV-2 infection. In order to improve the quality of diagnosis and treatment in dialysis patients with SARS-CoV-2 infection, we wrote this recommendation for primary care clinicians. During the epidemic period of SARS-CoV-2 infection, all patients should be instructed to strengthen self-management. Once the SARS-CoV-2 infection was found in dialysis patients, early stratified management should be carried out within 72 hours after the first positive nucleic acid or antigen test results, which includes early antiviral therapy, early recognition, and transferring severe patients from community or primary hospital to a referral hospital promptly. Guidance for dietary and sports rehabilitation after SARS-CoV-2 infection should also be started as soon as possible.

Objective:To explore the impact of weekend hospitalization on total hospitalization expenses for elderly patients with hip fracture under the geriatric orthopedic co-management.Methods:A retrospective analysis was conducted to analyze the clinical data of elderly patients with hip fracture who had been hospitalized for surgical treatment at Beijing Jishuitan Hospital from May 2015 to December 2020. They were divided into 2 groups based on their admission date. Group A was admitted from Monday to Thursday while Group B from Friday to Sunday. The general demographic data, diagnostic information, comorbidities, hospitalization expenses of the patients were collected. The differences in total hospitalization expenses, hospitalization time, rate of surgery within 48 hours and rate of hospital mortality between the 2 groups were analyzed by rank sum test, chi square test, correlation analysis, and multiple linear regression.Results:A total of 6,075 patients with hip fracture were included in this study, including 1,675 males and 4,400 females with a median age of 80 (74, 85) years. There were 3,935 ones in group A and 2,140 ones in group B. The total hospitalization expenses for group A was 58,160.52 (49,215.45, 72,748.94) yuan, insignificantly lower than those for Group B [58,412.90 (49,163.58, 72,712.61) yuan] ( P>0.05). The rate of surgery within 48 hours for group A was 75.8% (2,984/3,935), significantly higher than that for group B [49.3% (1,054/2,140)]. The hospitalization time for group A was 5 (4, 7) days, significantly less than that for group B [5 (4, 7) days] ( P<0.05). There was no significant difference in the rate of hospital mortality between the 2 groups ( P>0.05). Multiple linear regression analysis showed that total hospitalization expenses were significantly higher for patients admitted on weekends, hospitalization time was positively correlated with total hospitalization expenses, and total hospitalization expenses were significantly lower for the patients undergoing surgery within 48 hours ( P<0.05). Conclusion:Admission on weekends can increase total hospitalization expenses, prolong hospitalization time, and reduce rate of surgery within 48 hours for elderly patients with hip fracture.

Nevus-like basal cell carcinoma syndrome (NBCCS) is a rare autosomal dominant disease characterized by the occurrence of multiple maxillofacial keratocysts, basal cell carcinoma, child medulloblastoma, and various skeletal and soft tissue dysplasia. In 2020, a patient with NBCCS dominated by facial basal cell carcinoma was admitted to Xiangya Hospital of Central South University. The patient was an elderly woman. Ten years ago, the systemic mass appeared, especially on the face, but it was not treated. Later, these masses gradually increased in volume and number, and showed invasive properties. The nasal mass was broken and suppurated, seriously affecting the patient's life quality. The patient came to the hospital to improve the symptoms. Staphylococcus aureus and Providencia rettgeri were cultured in the patient's nasal secretions. Nasal sinus enhanced MRI showed that the subcutaneous soft tissue of the right cheek and the anterolateral mucosa of the left nasal cavity were invaded, indicating multiple malignant skin lesions. After admission, local anesthesia was performed and some masses were removed. Pathological examination of the mass showed basal cell carcinoma. After general anesthesia, multiple masses were resected. The postoperative pathological examination showed that multiple basal cell carcinoma invaded the deep dermis near subcutaneous fat layer. Combined with the results of clinical and immunohistochemical examination, the patient was diagnosed as NBCCS. There were no clear tumor thrombus in the vessel and no nerve invasion. No recurrence or new tumor was found after 1 year follow-up. The incidence rate of NBCCS is low and clinical symptoms are different. The patient's life quality is poor and the patient needs long-term individualized treatment.

Background Occupational noise-induced hearing loss (NIHL) is one of the most prevalent occupational diseases in the world. With the development of industry, noise sources in the workplace have become increasingly complex. Objective To apply kurtosis-adjusted cumulative noise exposure (CNE) to assess the occupational hearing loss among furniture manufacturing workers, and to provide a basis for revising noise measurement methods and occupational exposure limits in China. Methods A cross-sectional survey was conducted to select 694 manufacturing workers, including 542 furniture manufacturing workers exposed to non-Gaussian noise, and 152 textile manufacturing workers and paper manufacturing workers exposed to Gaussian noise. The job titles involving non-Gaussian noise were gunning and nailing, and woodworking, while those involving Gaussian noise were weaving, spinning, and pulping. High frequency noise-induced hearing loss (HFNIHL) and noise exposure data were collected for each study subject. Noise energy metrics included eight-hour equivalent continuous A-weighted sound pressure level (L_{Aeq,8 h}) and CNE. Kurtosis was a noise temporal structure metric. Kurtosis-adjusted CNE was a combined indicator of noise energy and temporal structure. Results The age of the study subjects was (35.64±10.35) years, the exposure duration was (6.71±6.44) years, and the proportion of males was 75.50%. The L_{Aeq,8 h} was (89.43±6.01) dB(A). About 81.42% of the study subjects were exposed to noise levels above 85 dB(A), the CNE was (95.85±7.32) dB(A)·year, with a kurtosis of 99.34 ± 139.19, and the prevalence rate of HFNIHL was 35.59%. The mean kurtosis of the non-Gaussian noise group was higher than that of the Gaussian noise group (125.33±147.17 vs. 5.86±1.94, t=−21.04, P<0.05). The results of binary logistic regression analysis showed that kurtosis was an influential factor of workers' HFNIHL after correcting for age, exposure duration, and L_{Aeq,8 h} (OR=1.49, P<0.05). The results of multiple linear regression analysis showed that the effects of age, exposure duration, L_{Aeq,8 h}, and kurtosis on noise-induced permanent threshold shift at frequencies of 3, 4, and 6 kHz of the poor hearing ear were statistically significant (all P<0.05). The results of chi-square trend analysis showed that when CNE ≥ 90 dB(A)·year, the HFNIHL prevalence rate elevated with increasing kurtosis (P<0.05). The mean HFNIHL prevalence rate was higher in the non-Gaussian noise group than in the Gaussian noise group (31.7% vs. 22.0%, P<0.05). After applying kurtosis-adjusted CNE, the linear equation between CNE and HFNIHL prevalence rate for the non-Gaussian noise group almost overlapped with that for the Gaussian noise group, and the mean difference in HFNIHL prevalence rate between the two groups decreased from 9.7% to 1.4% (P<0.05). Conclusion Noise kurtosis is an effective metric for NIHL evaluation. Kurtosis-adjusted CNE can effectively evaluate occupational hearing loss due to non-Gaussian noise exposure in furniture manufacturing workers, and is expected to be a new indicator of non-Gaussian noise measurement and assessment.

Non-alcoholic fatty liver disease (NAFLD) is a series of chronic liver diseases strongly associated with the metabolic disorder with an increasing rate of worldwide prevalence.Due to its complicated pathogenesis, only Saroglitazar has been approved by Indian Drug Controller General (DCGI) as a PPAR-α/γ dual agonist to treat non-cirrhotic non-alcoholic steatohepatitis.Combination therapy, which can target same or different signaling pathways of NAFLD pathogenesis, has been developed to achieve synergistic therapeutic efficacy.Currently, small-molecule drug combination, RNAi combination therapy, and chemogene therapy are proposed as promising strategies in NAFLD treatment.In addition, designing a smart, safe and effective drug delivery system is key to realizing the druggability, clinical translation and industrialization of small molecule drugs and gene drugs.This review summarizes the research status and delivery system of small-molecule drug combination, RNAi combination therapy, and chemogene therapy, in the hope of providing some novel insight for the treatment of NAFLD.

Objective:To analyze the clinical characteristics of severe adenovirus pneumonia with bacterial infection in children, so as to provide clinical evidences for early diagnosis and reliable treatment.Methods:A total of 72 pediatric cases with severe adenovirus pneumonia admitted to Pediatric Intensive Care Unit at the First People′s Hospital of Chenzhou from January 2018 to August 2019 were included.The clinical features, laboratory and imaging data, efficacy of the treatments and prognosis were investigated retrospectively.Patients were divided into with bacterial infection group and without bacterial infection group.The clinical characteristics were analyzed.Results:Among the 72 children, there were 54 males and 18 females, aging from 3 months to 5 years, including 37cases with bacterial infection and 35 cases without bacterial infection.Compared with the group without bacterial infection, the group with bacterial infection had longer heat duration and hospital stay [12.0 (10.0, 18.5) days vs.10.0 (9.0, 12.0) days; 6.0(4.0, 7.0) days vs.11.0(6.5, 16.0) days, P<0.05], the incidences of diarrhea and hepatomegaly were higher[35.1% (13/37) vs.14.3%(5/35); 45.9%(17/37)vs.8.6%(3/35), P<0.05], the proportion of five lobes involved in lung imaging was higher [91.8% (34/37) vs. 57.1%(20/35), P<0.05]. The incidences of complications with respiratory failure, hemophagocytic lymphohistiocytosis, and bronchiolitis obliterans in the group with bacterial infection were significantly higher than those of without bacterial infection group ( P<0.05). Conclusion:For children under 2 years old age with severe adenovirus pneumonia, there are prolonged high fever and extensive pulmonary lesions.We should be highly alert to the combination of bacterial infection and timely anti-infection therapy.Children with severe adenovirus pneumonia with bacterial infection have severe clinical manifestations and many complications with respiratory failure, hemophagocytic lymphohistiocytosis, and bronchiolitis obliterans.
