Abstract Objectives: Successful placement of a peripheral intravenous catheter (PIVC) on the first attempt is an important outcome for difficult vascular access (DVA) patients. This study compared standard technique, ultrasonography (USG), and near-infrared light (NIR) in terms of success in the first attempt in patients with DVA. Methods: This was a prospective, randomized controlled study. The study was conducted in a tertiary care hospital. Emergency department patients who describe DVA history, have no visible or palpable veins, and were assessed by the nurse to have a difficult PIVC were included to study. The PIVC procedure was performed on patients by standard, USG, or NIR device techniques. For all approaches, the success of the first attempt was the primary aim. Total procedure time, the total number of attempts, and the need for rescue intervention were secondary aims. Results: This study evaluated 270 patients. The first attempt success rates for USG, standard, and NIR methods were 78.9%, 62.2%, and 58.9%, respectively. The rate of first attempt success was higher in patients who underwent USG (USG versus standard, P = .014; USG versus NIR, P = .004; standard versus NIR, P = .648). The total median (IQR) procedure time for USG, standard, and NIR methods was 107 (69-228), 72 (47-134), and 82 (61-163) seconds, respectively. The total procedure time was longer in patients undergoing USG (standard versus USG, P <.001; NIR versus USG, P = .035; standard versus NIR, P = .055). The total median (IQR) number of attempts of USG, standard, and NIR methods were 1 (1-1), 1 (1-2), and 1 (1-2), respectively. A difference was found among the groups regarding the total number of attempts (USG versus NIR, P = .015; USG versus standard P = .108; standard versus NIR, P = .307). No difference was found among groups in terms of the need for rescue methods. Conclusion: It was found that USG increases the success of the first attempt compared with the standard method and NIR in patients with DVA.

In order to study the efficacy of linear-polarized near-infrared light irradiation (LPNIR) on relieving chronic pain in conjunction with nerve block (NB) or local block (LB), a 3-week prospective, randomized, double-blind, controlled study was conducted to evaluate the pre- and post-therapy pain intensity. Visual analogue scales (VASs) were measured in all patients before and 6 months after therapy visiting the pain clinic during the period of August 2007 to January 2008. A total of 52 patients with either shoulder periarthritis or myofascial pain syndrome or lateral epicondylitis were randomly assigned into two groups by drawing lots. Patients in Group I were treated with NB or LB plus LPNIR; Group II patients, for their part, were treated with the same procedures as in Group I, but not using LPNIR. In both groups, the pain intensity (VAS score) decreased significantly immediately after therapy as compared to therapy. There was a significant difference between the test and control groups immediately after therapy (P<0.05), while no effect 6 months later. No side effects were observed. It is concluded that LPNIR is an effective and safe modality to treat various chronic pains, which has synergic effects with NB or LB.

Abstract Objectives: Current evidence supporting the utility of electromagnetic (EM)-guided method as the preferred technique for nasoenteral feeding tube placement is limited. We conducted a meta-analysis to compare the performance of EM-guided versus endoscopic placement.Methods: We searched several databases for all randomized controlled trials evaluating the EM-guided vs. endoscopic placement of nasoenteral feeding tubes up to 28 July 2020. Primary outcome was procedure success rate. Secondary outcomes included reinsertion rate, number of attempts, placement-related complications, tube-related complications, insertion time, total procedure time, patient discomfort, recommendation scores, length of hospital stay, mortality, and total costs. Results: Four trials involving 536 patients were qualified for the final analysis. There was no difference between the two groups in procedure success rate (RR 0.97; 95% CI: 0.91-1.03), reinsertion rate (RR 0.84; 95% CI: 0.59-1.20), number of attempts (WMD -0.23; 95% CI: -0.99-0.53), placement-related complications (RR 0.78; 95% CI: 0.41-1.49), tube-related complications (RR 1.08; 95% CI: 0.82-1.44), total procedure time (WMD -18.09; 95% CI: -38.66-2.47), length of hospital stay (WMD 1.57; 95% CI: -0.33-3.47), ICU mortality (RR 0.80; 95% CI: 0.50-1.29), in-hospital mortality (RR 0.87; 95% CI: 0.59-1.28), and total costs (SMD -1.80; 95% CI: -3.96-0.36). The EM group was associated with longer insertion time (WMD 4.3; 95% CI: 0.2-8.39), higher patient discomfort level (WMD 1.28; 95% CI: 0.46-2.1), and higher recommendation scores (WMD 1.67; 95% CI: 0.24-3.10).Conclusions: EM-guided placement showed similar efficacy, safety and cost-effectiveness when compared with endoscopic placement of nasoenteral feeding tubes.

Antibiotic therapy is the gold standard for bacterial infections treatment. However, the rapid increase in multidrug-resistant (MDR) bacterial infections and its recent use for secondary bacterial infections in many COVID-19 patients has considerably weakened its treatment efficacy. These shortcomings motivated researchers to develop new antibacterial materials, such as nanoparticle-based antibacterial platform with the ability to increase the chances of killing MDR strains and prevent their drug resistance. Herein, we report a new black phosphorus (BP)-based non-damaging near-infrared light-responsive platform conjugated with ZnO and Au nanoparticles as a synergistic antibacterial agent against Staphylococcus aureus species. First, BP nanosheets containing Au nanoparticles were assembled in situ with the ZnO nanoparticles prepared by a low-temperature solution synthesis method. Subsequently, the antibacterial activities of the resulting Au–ZnO–BP nanocomposite against the non-resistant, methicillin-resistant, and erythromycin-resistant S. aureus species were determined, after its photothermal efficacy was assessed. The synthesized nanocomposite exhibited excellent anti-S. aureus activity and good photothermal characteristics. The non-resistant S. aureus species did not produce drug-resistant bacteria after the treatment of multiple consecutive passages under the pressure of the proposed nanoantibiotic, but rapidly developed resistance to erythromycin. This work clearly demonstrates the excellent photothermal antibacterial properties of Au–ZnO–BP nanocomposite against the MDR S. aureus species.
