Biosynthetic Prospective of Streptomyces Rationalizes GenomeBased Bioprospecting

Most salivary fistulas close with conservative management. NPWT potentially shortens fistula healing time while it achieves similar closure rates as conventional wound care. In the absence of contraindications, NPWT should be trialed on all salivary fistulas. Surgical management should be reserved for large, chronic, high-risk fistulas or those not responding to a trial of conservative treatment. Secondary reconstruction should be kept as simple as possible.

Pre-expanded pedicled flaps possess a more flexible transfer pattern and higher tissue utilization than random flaps, but the perfusion is fully dependent on the chosen axial vessels. A precise mapping of the vessels would assist the surgical design and increase the likelihood of success. The application of Infrared thermography (IRT) has been previously reported for perforator location. The aim of this study is to report the use of IRT in mapping the course and distribution of axial vessels in the pre-expanded flap to guide the designing and harvesting.
Patients who underwent head and neck reconstruction using pre-expanded flaps were included. After tissue expansion, IRT was used to mark the vessel distribution along the expanded flap. The results were compared with color Doppler ultrasound (CDU) and/or computed tomographic angiography (CTA). The flap was designed and raised based on the pre-operative marking by IRT. The mark was verified intraoperatively.
A total of 26 expanded flaps were performed, including 20 pedicled flaps and 6 free flaps. IRT succeeded to map the vessel distribution in all cases. All marked results were verified by CDU, CTA, and intraoperative dissection (26/26, 100%). IRT showed more comprehensive distribution of vascular branches than CDU or CTA, and could be utilized intraoperatively to identify the arteries.
IRT provides accurate and comprehensive mapping of the axial vessel distribution in the pre-expanded flaps, assisting with flap design and harvest. It is easy to use and non-invasive as an important tool pre- or intraoperatively to ensure the safe elevation.

This study was performed to explore the clinical application of the Nagata's technique for combing tissue expansion in auricular reconstruction.
The auricular reconstruction was performed in two surgical stages. At the first stage, an 80 ml expander was inserted in the mastoid region after preoperative evaluation. After a gradual expansion period and nearly 2-month rest time, the flap achieved the appropriate area and thickness. At the second stage, the expander was removed and a three-layer cartilage framework was inserted into the pocket through a Y-shaped lobule incision, and the earlobe and tragus were rebuild simultaneously.
From 2012 to 2016, 104 microtia patients underwent auricular reconstruction with this method in our hospital. Patients were followed up for between 6 months and 2 years. Ninety-six patients and their families were satisfied with the results, especially the clear outline, appropriate color, good projection, and the symmetry of bilateral ears. Complications of ischemic necrosis of the distal earlobe and skin of the concha cavity occurred in two cases, hematoma after the first stage occurred in two cases, and four patients needed further restorations.
A novel two-stage strategy combing tissue expansion and Nagata's technique is an effective and efficient technique for auricular reconstruction with satisfying medium-term results.

Metabolic diseases are risk factors for severe Coronavirus disease (COVID-19), which have a close relationship with metabolic dysfunction-associated fatty liver disease (MAFLD).
To evaluate the presence of MAFLD and fibrosis in patients with COVID-19 and its association with prognosis.
Retrospective cohort study. In hospitalized patients with COVID-19, the presence of liver steatosis was determined by computed tomography scan (CT). Liver fibrosis was assessed using the NAFLD fibrosis score (NFS score), and when altered, the AST to platelet ratio index (APRI) score. BMS202 price Mann-Whitney U, Student´s t-test, logistic regression analysis, Kaplan-Meier curves and Cox regression analysis were used.
432 patients were analyzed, finding steatosis in 40.6%. No differences in pulmonary involvement on CT scan, treatment, or number of days between the onset of symptoms and hospital admission were found between patients with and without MAFLD. The presence of liver fibrosis was associated with higher severity scores, higher levels of inflammatory markers, requirement of mechanical ventilation, incidence of acute kidney injury (AKI), and higher mortality than patients without fibrosis.
The presence of fibrosis rather than the presence of MAFLD is associated with increased risk for mechanical ventilation, development of AKI, and higher mortality in COVID-19 patients.

Recent evidences showed that the incidence of colorectal cancer decreased among older adults, yet this decline didn't appear in adults younger than 50 years. Our aim was to evaluate age-related incidence trends of colon and rectal cancers in China during 2005-2015.
A retrospective study of colon and rectal cancers was conducted using population-based data from the Chinese Cancer Registry Annual Report. Age at diagnosis was analyzed in five sub-groups (0-19, 20-34, 35-49, 50-64 and 65 years). Data including new cases, incidence, and age-standardized rates (ASRs) were classified by sex and area. Temporal trends of ASRs were determined with Joinpoint regression analysis.
From 2005 to 2015, colon cancer incidence decreased by -2.2% (95%CI -3.1, -1.3) per year. A more steady decrease was seen in rectal cancer with AAPC of -0.9% (95%CI -1.4, -0.4). Stratified by age at diagnosis, incidence trends followed a similar pattern, without age-related disparity. Females showed pronounced declines relative to males. The exception was that rural individuals showed opposite increasing trends, with 2.
