Hydrogel combined with antimicrobial protease dressing accompanied with emotional support to treat wounds of patients taking immunosuppressive agents: A longitudinal study.

BACKGROUND: This study aimed to evaluate the healing process of chronic wounds treated with hydrogel combined with antimicrobial protease dressing and emotional support intervention in patients taking immunosuppressive agents. CASES: The case series involved 8 patients treated at a tertiary public hospital for 12 weeks. Data were analysed by SPSS version 27.0. The intention-to-treat principle was carried out, without the loss or exclusion of the participants. The subjects had wounds for 70 (98) days, and they consisted of 50% (4/8) males with a mean age of 42.63 years (±16.94). All (100%) subjects had taken immunosuppressive agents, and 62.5% (5/8) had systolic hypertension. The mean initial area of all wounds was 19.54 (5.89) cm2, and the mean final area was 3.0 cm2, with a reduction rate of 89% over the 12 weeks of treatment. In addition, we found that tissue types of these wounds changed by using hydrogel combined with antibacterial protease dressings, especially devitalised tissue (P = 0.011). The amount of exudate did not statistically change (P = 0.083). No participant had severe or local adverse events during the study period. Hence, giving emotional support along with wound care for 12 weeks could significantly reduce anxiety scores (P = 0.012). These results suggested that hydrogel combined with antimicrobial protease dressing and emotional support intervention is a promising method for the healing of wounds in patients who suffer from immunosuppressive diseases or are receiving current immunosuppressive treatment.

LINC00116 Is a Novel Prognostic Biomarker of Nonsmall Cell Lung Cancer.

Purpose: Lung cancer is the most malignant respiratory cancer with an undesirable prognosis. Emerging evidence shows that long noncoding RNAs (lncRNAs) can regulate lung cancer development. Currently, the role of LINC00116, a novel lncRNA, in lung cancer is unknown. This study was designed to evaluate the association and clinical significance between the level of LINC00116 and lung cancer. Materials and Methods: In the present study, 19 paired lung cancer and non-cancerous adjacent tissues were collected from lung cancer patients to measure the expression of LINC00116 by quantitative reverse transcription-polymerase chain reaction and Microarray analysis (Oncomine and CCLE). Clinicopathological features of patients were obtained to analyze their relationships with LINC00116 expression levels. Kaplan-Meier survival analysis was used to analyze the prognosis. Results: LINC00116 expression was upregulated in lung cancer. Furthermore, we found that LINC00116 expression was correlated with pT factor, pN factor, pTNM stage, smoking history, differentiation, and Ki-67 labeling index (p < 0.05). In addition, Kaplan-Meier survival analysis showed that high levels of LINC00116 expression were associated with poorer overall survival (OS), progression-free survival (PFS) and first progression (FP) (p < 0.05) of lung cancer patients. Conclusions: Our study provided evidence that LINC00116 is upregulated in lung cancer tissues and can predict poor survival. It might also be able to serve as a therapeutic target.

Analysis of risk factors for femoral head necrosis after internal fixation in femoral neck fractures.

Femoral head necrosis is a rare but devastating complication following femoral neck fracture. The reported incidence of avascular necrosis after femoral neck fracture fixation varies widely, and there is no consensus regarding its risk factors. The aim of this study was to analyze the risk factors for femoral head necrosis after internal fixation in femoral neck fracture. This retrospective study included 166 patients with femoral neck fractures treated with surgical reduction and internal fixation at the authors' institution from January 2004 to December 2008. Eight patients died for reasons unrelated to the surgery, and 12 patients were lost to follow-up. The remaining 146 patients (146 fractures) were followed until union or until conversion to total hip arthroplasty. The patients included 61 males and 85 females with an average age of 47.5 years (range, 18-68 years). The authors analyzed the following factors: age, sex, Garden classification, reduction quality, surgical methods, injury-to-surgery interval, preoperative traction, weight-bearing time, and implant removal. All patients were followed for a mean of 52 months (range, 6-90 months). The incidence of femoral head necrosis was 14.4% (21/146). Garden classification (P=.012), reduction quality (P=.008), implant removal (P=.020), and preoperative traction (P=.003) were significantly associated with femoral head necrosis. Patient age (P=.990), sex (P=.287), injury-to-surgery interval (P=.360), weight-bearing time (P=.868), and surgical methods (P=.987) were not significantly associated with femoral head necrosis. In multivariate logistic regression analysis, implant removal was not a significant risk factor for femoral head necrosis development (P=.498). Garden classification, reduction quality, and preoperative traction had a significant effect on femoral head necrosis development.
