Abstract

The use of naturally sourced organic materials with chirality, such as the M13 bacteriophage, holds intriguing implications, especially in the field of nanotechnology. The chirality properties of bacteriophages have been demonstrated through numerous studies, particularly in the analysis of liquid crystal phase transitions, developing specific applications. However, exploring the utilization of the M13 bacteriophage as a template for creating chiral nanostructures for optics and sensor applications comes with significant challenges. In this study, the chirality of the M13 bacteriophage was leveraged as a valuable tool for generating helical hybrid structures by combining it with nanoparticles through an evaporation-induced three-dimensional (3D) printing process. Utilizing on the self-assembly property of the M13 bacteriophage, metal nanoparticles were organized into a helical chain under the influence of the M13 bacteriophage at the meniscus interface. External parameters, including nanoparticle shape, the ratio between the bacteriophage and nanoparticles, and pulling speed, were demonstrated as crucial factors affecting the fabrication of helical nanostructures. This study aimed to explore the potential of chiral nanostructure fabrication by utilizing the chirality of the M13 bacteriophage and manipulating external parameters to control the properties of the resulting hybrid structures.

Abstract

Background The early detection of infectious complications of colorectal surgery leads to better patient outcomes. This study aimed to assess the role of C-reactive protein (CRP), white blood cell count (WBC), and serum glucose in the early prediction of infectious complications of laparoscopic colorectal surgery.Methods Patients who underwent laparoscopic colorectal surgery were included and stratified into two groups: infectious complication (IC) or no infectious complication (non-IC). Serum levels were measured on postoperative days (PODs) 2 and 4.Results Analysis of 224 patients (IC group: 27, Non-IC group: 197) revealed higher CRP levels in IC group on POD 2 (P= .001). On POD 4, CRP levels and WBC counts were higher in IC group (P<.001, P= .011, respectively). The area under the curve (AUC) of the receiver operating characteristic (ROC) for CRP on PODs 2 and 4 were .743 and .907, respectively, and for WBC on POD 4 was .687. The cut-offs of CRP on PODs 2 and 4 were 156.2 mg/L and 91.3 mg/L, respectively; the cut-off of WBC was 7,220 cells/mm3. Sensitivity of CRP level ≥91.3 mg/L or WBC count ≥7,220 cells/mm3was 96.3%; (cf. 88.9% for CRP alone), and specificity of CRP level ≥91.3 mg/L and WBC count ≥7,220 cells/mm3was 93.4% (cf. 82.2% for CRP alone).Discussion The CRP level on postoperative day (POD) 2 and the combined CRP and WBC on POD 4 were meaningful in predicting infectious complications after laparoscopic colorectal surgery. However, serum glucose levels had a low predictive value for infectious complications.

Abstract

Internal hernia after gastrectomy is a rare but potentially life-threatening condition without surgical intervention. Clinical risk factors of internal hernia should, hence, be reviewed after gastrectomy. From 2008 to 2018, patients who underwent gastrectomy for gastric cancer were investigated.Abdominal computed tomography (CT) was used to screen for internal hernia, and surgical exploration was performed to confirm the diagnosis. Using retrospective statistical analysis, the incidence, characteristics, and risk factors were identified, and the characteristics of the internal hernia group were reviewed.The overall incidence of internal hernia was 0.9%. From statistical analysis, it was found that laparoscopic surgery was almost five times riskier than open gastrectomy (odds ratio [OR], 4.947; 95% confidence interval [CI], 1.308-18.710;Suspecting an internal hernia should be an important step when a patient with a history of laparoscopic gastrectomy visits for medical care. When suspected, emergent screening through CT scan and surgical intervention should be considered as soon as possible to prevent lifetime complications accordingly.
