t therapy than in patients who underwent surgery alone. Patients in the former group had larger tumors and more lymph node metastases, and this difference in baseline characteristics could explain their higher recurrence rate. The recurrence rate was lower in patients with small tumors, and RAI adjuvant therapy would likely not play a major role in T1-2N1bM0 patients.

Epistaxis is a commonly encountered condition; however, factors that have been associated with epistaxis are controversial. Although several previous studies have evaluated the relationship between meteorological factors and epistaxis, studies conducted in Korea has been nearly reported. We attempted to evaluate the meteorological factors associated with the frequency of patients presenting with epistaxis in a tertiary hospital.

We retrospectively reviewed the medical records of patients presenting with spontaneous epistaxis in an urban tertiary medical center, during one year. Patients with a clear etiology for epistaxis (such as trauma, previous surgery) were regarded as cases of secondary epistaxis and were excluded from this study. Daily climatic data were collected from the website of Korea Meteorological Administration. Meteorological factors affecting the frequency of patients presenting with epistaxis were statistically analyzed.

Among 350 enrolled subjects, 219 were males and 131 were females, perature and mean relative humidity were associated with number of patients presenting with epistaxis. Our findings suggested that these meteorological factors might affect the spontaneous epistaxis in Seoul, Korea.

Percutaneous device closure of atrial septal defect (ASD) is the gold-standard treatment, but several delayed complications may occur as a result of incomplete device endothelialisation.

In this in vitro study, we compared three ASD closure devices [Nit-Occlud® ASD-R (device 1); Hyperion™ ASDO (device 2); and Amplatzer™ Septal Occluder (device 3)] in terms of the endothelialisation process, using human endothelial progenitors cells (EPCs), and haemocompatibility.

EPCs from umbilical cord blood were extracted, cultured and characterised. Device samples were seeded with 100,000 cells/cm

. EPC adhesion was investigated at 3 and 24hours, and EPC proliferation was monitored, which allowed longitudinal follow-up (days 1-12). Haemocompatibility of device samples was assessed using a complement C3a assay and platelet and coagulation activation.

With regard to EPC adhesion and proliferation, no statistically significant differences were found between the three devices. We observed for each device a significant time-dependent EPC proliferation, appearing at day 8 for devices 2 and 3 and day 10 for device 1. No complement or platelet activation occurred within 15minutes of contact with devices. However, there was minimal activation of coagulation for the three devices.

In this in vitro study we showed that, despite the three ASD occluders having different device designs and coatings, adhesion and proliferation of human endothelial cells was similar for all devices. This should be further confirmed by similar studies including shear stress forces and anti-thrombotic treatments.

Electroanalytical techniques were used to analyze the electrocatalytic activity of the TMC biofilm formed onto the electrodes. The developed electromethanogenesis process enhanced the yield of methane by 54.7% than control experiments. Scanning electron micrographs of the TMC bioelectrodes showed that the electrosynthesis process accelerates biofilm formation onto the electrodes leading to enhanced direct electron transfer reactions at electrode-electrolyte interface. This study will help in developing a novel approach for valorization of food and paper waste to biofuels.Ayurveda has a rich history and its significance woven deeply in the Indian culture. The concept of prakriti (a person's "nature" or constitutional type determined by the proportion of three doshas, namely - vata, pitta and kapha) in Ayurveda is deeply rooted in personalized health management. While the attributes of prakriti has been established to have a genomic basis, there is dearth of elaborate evidences linking prakriti with manifestation of diseases. Next generation sequencing studies have provided a causal link between variation in the gut microbiome and its effect on an individual's fitness. Separately, reports have identified gut microbial patterns associated with several host variables such as geography, age, diet and extreme prakriti phenotypes. Recently, few reports have identified a "core gut microbiome" consisting of Bacteroides, Faecalibacterium, Prevotella and Ruminococcus prevalent across the Indian population; however, a few bacterial genera were specifically enriched in certain prakritis. Hence, in this review we aim to analyse the role of prakriti variations on dysbiosis of the gut microbiome and concomitantly its effect on human health. We suggest that prakriti phenotyping can function as a potential stratifier of the gut microbiome in a given population and may provide evidence for the conceptual framework of personalized medicine in Ayurvedic system of medicine.

The use of indocyanine green during laparoscopic cholecystectomy has been postulated to help to define anatomy. Studies have not specifically evaluated patients with acute cholecystitis. We sought to assess whether use of indocyanine green can decrease the rate of bail-out operation (subtotal cholecystectomy or conversion to an open operation) in an acute care surgery population where acute cholecystitis is more frequent.

Using a retrospective cohort design, we examined all inpatient cholecystectomies performed by the acute care surgery service under urgent or semiurgent (biliary colic as the presentation in the emergency room) conditions at a single institution from 7/1/18 to 6/30/19 during which indocyanine green was available for use at the surgeon's discretion.

A total of 198 patients were included in the analysis. check details Demographic variables were similar in groups receiving indocyanine green versus not. Pathology confirmed acute cholecystitis was present in 96 of 198 (48.5%) patients; of those, 55 (57.2%) received indocyanine green.
