  • Vacuum assisted closure (VAC)/negative pressure wound therapy (NPWT) for difficult wounds: A review. [Review]
    J Clin Orthop Trauma 2019 Sep-Oct; 10(5):845-848Agarwal P, Kukrele R, Sharma D
  • Delayed wound healing particularly in difficult wounds and in elderly with co morbidities is a major concern. It leads to the pain, morbidity, prolonged treatment, and require major reconstructive surgery which imposes enormous social and financial burden. Vacuum-assisted closure (VAC) is an alternative method of wound management, which uses the negative pressure to prepare the wound for spontane…
  • Chest Tube Drainage Devices. [Journal Article]
    Semin Respir Crit Care Med 2019; 40(3):386-393Toth JW, Reed MF, Ventola LK
  • Placement of a chest tube drains intrapleural fluid and air. The tube should be attached to a drainage system, such as one-, two-, or three-compartment devices, a one-way (Heimlich) valve for ambulatory drainage, a digital system, or a vacuum bottle. The frequently employed three-compartment systems, currently integrated disposable units, allow adjustment of negative pressure or no suction (water…
  • Postoperative Esophageal Leaks in Malignant Pathology - Optimal Management: A Systematic Review. [Journal Article]
    Chirurgia (Bucur) 2019 Jul-Aug; 114(4):429-436Birla R, Hoara P, … Constantinoiu S
  • CONCLUSIONS: In patients with mediastinal postoperative esophageal fistulas, diagnosis and management represent a real challenge for the surgeon-endoscopist-therapist team. The early diagnosis and the establishment of an optimal therapy to address the parietal defect and the biological status of the patient are mandatory conditions for resolving this postoperative complication.
  • Ring-core fiber with negative curvature structure supporting orbital angular momentum modes. [Journal Article]
    Opt Express 2019; 27(15):20358-20372Tu J, Liu Z, … Lu C
  • Compared to glass walls with a positive curvature, those with a negative curvature have been proven to have stronger confinement of light. Therefore, we change the multi-layered air holes in a photonic crystal fiber into several negative curvature tubes. As a result, the confinement medium is shifted from a low-index cladding material into a special structure. The theoretical analysis shows that …
  • A Compact, Syringe-Assisted, Vacuum-Driven Micropumping Device. [Journal Article]
    Micromachines (Basel) 2019; 10(8)Wang A, Koh D, … Oh KW
  • In this paper, a simple syringe‑assisted pumping method is introduced. The proposed fluidic micropumping system can be used instead of a conventional pumping system which tends to be large, bulky, and expensive. The micropump was designed separately from the microfluidic channels and directly bonded to the outlet of the microfluidic device. The pump components were composed of a dead‑end channel …
