Background:
Sleep is an important physiological process that is required to perform daily functions. Sleep duration is reported to be correlated withobesity. This study investigated the association between sleep duration and abdominal obesity in Korean adult male.
Methods:
We used data from the seventh Korean National Health and Nutrition Examination Survey conducted during 2016–2017. In total, 3,997 maleaged >20 years were included. The frequency and weighting percentage of sleep duration were calculated. Chi-square test was performed withRao–Scott calibration. Logistic regression was performed to evaluate the association of sleep duration with abdominal obesity.
Results:
The overall effect of abdominal obesity on sleep duration was significant. The probability of developing abdominal obesity when the averagesleep duration was below than 5 hours was 1.495 times higher than that when it was 7 hours.
Conclusion
Sleep duration was related to abdominal obesity in Korean adult male.

PURPOSE: DNA flow cytometry is a simple and easy method to assess the DNA content and the cell-cycle distribution of a tumor cell. The prognostic significance of the DNA content and the S-phase fraction in a gastric carcinoma has been controversial. The purpose of this study was to evaluate the prognostic significance of the nuclear DNA content and the S-phase fraction in patients with a gastric carcinoma. METHODS: Between May 1995 and March 1996, 94 patients who were underwent a gastric resection for a gastric carcinoma were evaluated with DNA flow cytometry. Of them, 88 patients underwent a gastric resection with curative intent. The relationship of variable clinicopathological factors and of recurrence pattern to survival and nuclear DNA content were assessed. RESULTS: The mean age was 55 years. 55 patients (58.5%) exbitied diploidy and 39 patients (41.5%) aneuploidy. There was no relationship between the clinicopathological factors and either the ploidy pattern or the S-phase fraction. Though the recurrence and its pattern were not different between the two ploidy group (p=0.860, 0.137), diploidy tended to recur locoregionally and aneuploidy hematogenously. CONCLUSION: The ploidy pattern was a significant prognostic factor in gastric carcinomas, but should be interpreted carefully.

Stomach cancer has a high annual mortality rate worldwide necessitating early detection and accurate treatment. Even experienced specialists can make erroneous judgments based on several factors. Artificial intelligence (AI) technologies are being developed rapidly to assist in this field. Here, we aimed to determine how AI technology is used in gastric cancer diagnosis and analyze how it helps patients and surgeons. Early detection and correct treatment of early gastric cancer (EGC) can greatly increase survival rates. To determine this, it is important to accurately determine the diagnosis and depth of the lesion and the presence or absence of metastasis to the lymph nodes, and suggest an appropriate treatment method. The deep learning algorithm, which has learned gastric lesion endoscopyimages, morphological characteristics, and patient clinical information, detects gastric lesions with high accuracy, sensitivity, and specificity, and predicts morphological characteristics. Through this, AI assists the judgment of specialists to help select the correct treatment method among endoscopic procedures and radical resections and helps to predict the resection margins of lesions.Additionally, AI technology has increased the diagnostic rate of both relatively inexperienced and skilled endoscopic diagnosticians. However, there were limitations in the data used for learning, such as the amount of quantitatively insufficient data, retrospective study design, single-center design, and cases of non-various lesions. Nevertheless, this assisted endoscopic diagnosis technology that incorporates deep learning technology is sufficiently practical and future-oriented and can play an important role in suggesting accurate treatment plans to surgeons for resection of lesions in the treatment of EGC.

The N-terminal fragment of prohormone brain natriuretic peptide (NT-proBNP) is a commonly used biomarker for the diagnosis of congestive heart failure, although its biological function is not well known. NT-proBNP exhibits heavy O-linked glycosylation, and it is quite difficult to develop an antibody that exhibits glycosylation-independent binding. We developed an antibody that binds to the recombinant NT-proBNP protein and its deglycosylated form with similar affinities in an enzyme immunoassay. The epitope was defined as Gly63-Lys68 based on mimetic peptide screening, site-directed mutagenesis and a competition assay with a peptide mimotope. The nearest O-glycosylation residues are Thr58 and Thr71; therefore, four amino acid residues intervene between the epitope and those residues in both directions. In conclusion, we report that an antibody reactive to Gly63-Lys68 of NT-proBNP exhibits O-glycosylation-independent binding.

OBJECTIVE: To compare the effect of two different hand exercises on hand strength and vascular maturation in patients who underwent arteriovenous fistula surgery. METHODS: We recruited 18 patients who had chronic kidney disease and had undergone arteriovenous fistula surgery for hemodialysis. After the surgery, 10 subjects performed hand-squeezing exercise with GD Grip, and other 8 subjects used Soft Ball. The subjects continued the exercises for 4 weeks. The hand grip strength, pinch strength (tip, palmar and lateral pinch), and forearm circumference of the subjects were assessed before and after the hand-squeezing exercise. The cephalic vein size, blood flow velocity and volume were also measured by ultrasonography in the operated limb. RESULTS: All of the 3 types of pinch strengths, grip strength, and forearm circumference were significantly increased in the group using GD Grip. Cephalic vein size and blood flow volume were also significantly increased. However, blood flow velocity showed no difference after the exercise. The group using Soft Ball showed a significant increase in the tip and lateral pinch strength and forearm circumference. The cephalic vein size and blood flow volume were also significantly increased. On comparing the effect of the two different hand exercises, hand-squeezing exercise with GD Grip had a significantly better effect on the tip and palmar pinch strength than hand-squeezing exercise with Soft Ball. The effect on cephalic vein size was not significantly different between the two groups. CONCLUSION: The results showed that hand squeezing exercise with GD Grip was more effective in increasing the tip and palmar pinch strength compared to hand squeezing exercise with soft ball.

PURPOSE: It is important to begin a transfusion safely and appropriately as soon as possible in a hemorrhagic shock patient. A group O+ unmatched pack red blood cell (universal O+) transfusion may satisfy that requirement. We report our experiences with universal O+ to compare its usefulness for hemorrhagic shock patients with that of a matched pack red blood cell transfusion in the emergency department (ED). METHODS: This is a retrospective study. Patients who had systolic blood pressure of less than 90 mmHg or a pulse rate of more than 120 beats per minute in the ED were included, and their medical records were reviewed. The collected data were demographic data, vital signs, blood test results, time to transfusion, the amount of transfusion, complications, and diagnoses. We calculated the emergency transfusion score (ETS) based on the patients' medical records. RESULTS: Two hundred thirty-five patients were included. Forty-eight patients (36 trauma and 12 non-trauma patients) were transfused with a universal O+. These patients had less time to transfusion compared with the cross-matched transfusion groups (35+/-42 versus 170+/-187 minutes, p<0.001). There were no differences in complications between groups (p=0.076). Of the patients who were transfused with universal O+, 94.4% got more than 3 ETS. CONCLUSION: The universal O+ transfusion, compared with matched pack red blood cell transfusion, should be a useful treatment for ED hemorrhagic shock patient due to its having a shorter time to transfusion without an increase in complications.

Polydeoxyribonucleotide (PDRN) is safe and effective in wound healing, cellular growth, synthesis of extracellular matrix protein, and inflammation reduction via activation of adenosine A2 receptors. We report a 28-year-old male patient treated with PDRN injections for chronic non-healing wound refractory to negative pressure wound therapy, skin graft, or growth factors. Three injections of PDRN were administered at the wound site into the anterior and medial sides of the left stump on the 1st, 4th, and 9th days of hospitalization. The PDRN ameliorated wound healing by enhancing cell growth, tissue repair, and angiogenesis. PDRN application represents a potential treatment for non-healing wounds obviating the need for additional therapies, and hospitalization, as well as improve patient’s activities of daily living.

Purpose:
We investigated the effects of cold water immersion (CWI) treatment during half-time break on performance related physiological indices during second half soccer match.
Methods:
Twenty-two collegiate soccer players participated in the study. Subjects undertook 3 minutes head out seated with whole body immersion at 19 o C to 21 o C. Total four venous blood samples were collected and analyzed for markers of ionic regulations and inflammatory (interleukin [IL]-1b, IL-6, IL-8, IL-10, tumor necrosis factor-α , and vascular endothelial growth factor) and immune functions (immunoglobulin [Ig] G, IgG2, IgG2, IgG3, IgG4, IgA, and IgM).
Results:
Partial oxygen concentration and %SO 2 level was lowered in CWI. Hemoglobin and hematocrit values were not significantly different between experimental groups. While there was no notable effect was shown in Na + and Ca 2+ , K + concentration was higher in CWI during second half match. There were no effects in any of inflammatory and/or anti-inflammatory cytokines and Ig.
Conclusion
These results suggest that CWI during half time break exert positively affects in buffering capacity and promote oxygen delivery to the actively recruited skeletal muscle, possibly results in improve soccer performance during second half match.
