In conclusion, we found a significant correlation between the FeNO concentration and the level of asthma symptom control in asthmatic patients with and without AR.A telemetry system based on Bluetooth Low Energy (BLE) was constructed to simultaneously collect locomotor activity and physiological signals of small animal cohorts for circadian rhythm experiments; it consists of miniature transmitters and mobile phone with customized App. The continuous sampling signals obtained from the 3-axis acceleration and temperature sensors in the transmitters are sent to the mobile phone in real-time through Internet of Things (IoT) for temporary storage and then imported into the computer for summary and rhythm analysis by the general open-source mathematical software. Unlike expensive and complicated commercial telemetry systems with industrial wireless standards, no special data receivers and software are needed. In our validation experiment, six rats were divided into two groups under natural dark and light-dark cycles. For two consecutive weeks, the transmitter mounted on the head of the rat-recorded locomotor activity, skin temperature, and ambient temperature of each rat at a frequency of 6 Hz. After processing with Local Weighted Regression Scatter Smoothing (LOWESS) and Fast Fourier Transform (FFT) filtering, single cosinor and multi-components cosinor were then used to assess and characterize the circadian rhythm. The results showed that the rhythm values of the two groups of rats coincided with the corresponding light-dark cycle, and that the system was robust to data loss and error from BLE communication failures. Therefore, the proposed system provides a light-weight framework for long-term circadian rhythm monitoring in free-moving rodents to further simplify and promote experimental chronobiology animal studies.The aim of this study was to investigate the outcomes and complications after posterior ankle arthroscopy for the treatment of posterior ankle impingement syndrome, in a local population with a single surgeon series. Two-portal posterior ankle or hindfoot arthroscopy is an alternative option to open surgery in cases of posterior ankle impingement, that showed similar results but with less morbidity and faster recovery. There has been increasing interest in minimally invasive surgical techniques. Indications include extra- and intra-articular conditions and range from bony, cartilaginous to soft tissue pathology. Posterior ankle arthroscopy has been shown to be a good option in cases that are refractory to a period of conservative therapy. Posterior ankle arthroscopy also has known complications of sural nerve damage laterally and neurovascular bundle injury medially and also a steep learning curve that has been studied in the context of os trigonum excision. There have been few or no studies on the local Singaporean population and this article seeks to describe the various indications, results, and complications in the local Singaporean population by a single surgeon.Levels of Evidence Level IV Case series.Candida albicans and Staphylococcus epidermidis are important opportunistic human pathogens, which form mixed-species biofilms and cause recalcitrant device associated infections in clinical settings. Further to many reports suggesting the therapeutic potential of plant-derived monoterpenoids, this study investigated the interaction of the monoterpenoids carvacrol (C) and thymol (T) against mono- and mixed-species growth of C. albicans and S. epidermidis. C and T exhibited synergistic antimicrobial activity. The time-kill study and post-antimicrobial effect results revealed the effective microbicidal action of the C + T combination. Filamentation, surface coating assays and live-dead staining of biofilms determined the anti-hyphal, antiadhesion, and anti-biofilm activities of the C + T combination, respectively.  https://www.selleckchem.com/products/guanosine.html  Notably, this combination killed highly tolerant persister cells of mono-species and mixed-species biofilms and demonstrated less risk of resistance development. The collective data suggest that the C + T combination could act as an effective therapeutic agent against biofilm associated mono-species and mixed-species infections of C. albicans and S. epidermidis.Background No randomized trial has compared the yield of the ProCore needle, a novel needle for endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA), with standard needles.Research design and methods Consecutive subjects with intrathoracic lymphadenopathy due to suspected sarcoidosis were randomized 11 to undergo EBUS-TBNA with either the 22-gauge ProCore (EchoTip-ProCore, Cook-Medical) or the 22-gauge standard (Vizishot, Olympus) needle. The primary outcome was the diagnostic sensitivity; the secondary outcomes included the number of adequate aspirates obtained and procedure-related complications.Results We randomized 100 (mean age, 43.4 years; 53% women) subjects. Of the 84 subjects finally diagnosed with sarcoidosis, the sensitivity of EBUS-TBNA was higher with the ProCore (36/42, 85.7%) versus the standard needle (31/42, 73.8%), although not statistically significant (p = 0.18). We obtained adequate aspirates in 95.2% and 90.5% subjects in the ProCore and the standard needle groups, respectively (p = 0.68). One complication (transient hypoxemia) occurred in each group. There were two incidences of the ProCore needle getting bent during the procedure.Conclusions We found no difference in the sensitivity, specimen adequacy, or safety of EBUS-TBNA when performed with the ProCore or the Olympus needle in subjects with sarcoidosis. Larger studies are required to confirm our findings.[clinicaltrials.gov NCT03656003].
  Recent evidence from randomized controlled trials has raised concerns about the long-term safety of paclitaxel-coated peripheral devices used for femoropopliteal artery revascularization. In response to a call for more real-world data on the safety of these devices, the SAFE-PAD study (Safety Assessment of Femoropopliteal Endovascular treatment with Paclitaxel-coated Devices) was designed with input from the Food and Drug Administration to provide a long-term, comprehensive evaluation of the mortality risk associated with paclitaxel-coated devices among Medicare beneficiaries.
 
  SAFE-PAD is an observational cohort study of fee-for-service Medicare beneficiaries that underwent femoropopliteal artery revascularization with either a drug-coated device or nondrug-coated device from 2015 through 2018. All patients age 66 years or older who underwent revascularization will be identified using a combination of 
  procedural codes, Current Procedural Terminology codes, and Healthcare Common Procedure Coding System C-codes.
