PURPOSE: This study investigated the effects of shoulder protraction exercise according to weight by examining the surface electromyography (EMG) amplitude in the serratus anterior (SA), upper trapezius (UT), and pectoralis major (PM) as well as the activity ratio of each muscle. METHODS: Twenty three winging scapula subjects participated in the study. The subjects performed scapula protraction at shoulder 90° flexion and 60° horizontal abduction with up to four (none, 1kg, 1.5kg, and 2kg) dumbbells in the supine position. The EMG data were collected from the dominant side muscles during a shoulder protraction exercise according to weight in the supine position. One way repeated measures analysis of variance (ANOVA) was used to compare the normalized activities of the SA, UT, and PM and the ratios of PM/SA and UT/SA. RESULTS: The results showed that the activities of both the SA and UT were highest for the shoulder protraction exercise at 2kg in the supine position. The UT/SA ratio also was the lowest for exercise at 2kg. On the other hand, the activities of both the UT and PM/SA ratio were similar under all conditions. CONCLUSION: These results show that there is a need to selectively strengthen the SA muscle in the case of patients with the shoulder dysfunction. In particular, it is necessary to weigh 2kg when performing shoulder protraction exercises in the supine position to activate the SA muscle in patients with a winging scapula.

Understanding anatomic variations in neurovascular structure inside the femoral triangle is crucial for regional anesthesiologists performing femoral nerve block. During routine dissection of a cadaver, an ascending branch of the lateral circumflex femoral artery with an anomalous course passing through the femoral nerve, specifically the posterior division, was identified inside the femoral triangle on the left thigh. The novel variation identified in this study occurred in an early stage of prenatal development. Recognition of this anatomic variation will be helpful for reducing unexpected complications during the femoral nerve block and the tensor fascia latae flap. Penetration of the posterior division of the femoral nerve by the arterial branch might cause pain or paresthesia of the medial aspect of the leg in the distribution of the saphenous nerve.

This study aimed to clarify the anatomy of middle rectal artery and pelvic vasculature patterns, and to provide schematic information in a manner applicable to the total mesorectal excision. Forty sides of pelvis from 20 formalinembalmed cadavers (10 male, 10 female) were dissected, and all the pelvic vasculatures from the internal iliac artery were investigated, focusing on the middle rectal artery. Middle rectal arteries were classified into major types depending on their vascular origins. Each type was subdivided into minor types according to variability of the pelvic vasculature. A middle rectal artery was identified in 18 out of 20 cadavers, and in 25 out of 40 pelvic sides. In most cases, the middle rectal artery originated from the internal pudendal artery or inferior gluteal artery. These two arteries arose directly from the anterior trunk of the internal iliac artery or were bifurcated from the gluteal-pudendal trunk. In rare cases, these arteries arose from the posterior trunk of the internal iliac artery. The other origins of the middle rectal artery included the gluteal pudendal trunk, inferior vesical artery, internal iliac artery, obturator artery, and the prostatic artery, and the pelvic vasculatures in these cases also presented variability. The detailed anatomical findings related to the middle rectal artery and pelvic vasculatures are noteworthy for their improved clinical applicability.

BACKGROUND: Falling in elderly has caused high mortality and morbidity rates. But research papers about falling in elderly are rate in Korea. We examined preventive methods from falling in institutionalized elderly. METHODS: Subjects were 163 older adults residing in a nursing home. Investigators interviewed the subjects by questionnaries about falling, associated factors, environmental factors, and change after falling during last one year. We examined geriatric depression scale(GDS), mini mental status exam-Korea(MMSEK), Katz`s activities of daily living(ADL), Lawton`s instrumental activities of living. Also, we reviewed medical record. We use the student t-test and chi-sqrare test. RESULTS: The total number of 152 subjects were consisted of 69 men and 83 women, with the mean age of 78.8. 30.3% of subjects have experienced falling during last one year, 57.2% of them have had fear of falling, and subjects with gait abnormality were 38.8% Falling occurred most commonly in summer (32.6%) around 2pm(27.7%) on the road(26.1%), because of tripping over(37.3%) during walking (32.3%), on cement(50.5%), with slippers on (56.5%). The injured subjects by falling were 84.8% and serious injuries(fracture, sutured laceration, joint dislocation or sprain, head injury with altered consciousness, hospitalization) were 19.6%. Injuried part of the body is most common in leg (46.2%) 30.4% of subjects visited hospital or emergency room after falling. Falling resulted in decreasing activity in 52.2% of subject. The factors that were significantly associated with falling were fear of falling (p<0.05), depression (p<0.05). Past history of falling, impairment of cognitive function, dizziness were weakly associated with falling. But age, hearing visual acuity, gait abnormality, ADL, anemia, degenerative arthritis were not associated with falling. CONCLUSIONS: The prevalence of falling in elderly was high. Fear of falling and depression were significantly associated with falling. Activity is decreased after falling.

Sunitinib, a multi-targeted tyrosine kinase inhibitor, is used for the treatment of renal cell carcinoma and gastrointestinal stromal tumors. Many adverse effects associated with sunitinib, including hypertension, proteinuria, and thrombotic microangiopathy, have been reported; however, the other forms of glomerulonephritis are very rare. We report a case of biopsy-confirmed immune complex glomerulonephritis in a patient with a gastrointestinal tumor who received sunitinib treatment. The proteinuria subsided partially after sunitinib was discontinued, but when the drug was reintroduced, it recurred.

The use of intestinal segments in the reconstruction and plasty of urinary bladder for malignant or nonmalignant conditions is widely accepted. Metabolic derangements including hyperchloremic metabolic acidosis and malabsorption of lipid may occur after surgery. Main pathophysiology of hyperchloremic metabolic acidosis is the exchange of urinary chloride with luminal bicarbonate and duration of urine in contact with the intestinal mucosa can affect the severity of metabolic acidosis. We experienced two cases of severe hyperchloremic metabolic acidosis which developed in patients with chronic kidney disease, urinary tract infection and orthotopic neobladder or augmentation enterocystoplasty for the treatment of bladder cancer and neurogenic bladder, respectively.

Background/Aims:
The effect of hyperammonemia on the mortality in patients with liver cirrhosis is well documented. However, little is known about the impact of hyperammonemia on mortality among intensive care unit patients without hepatic disease. We aimed to investigate factors associated with non-hepatic hyperammonemia among intensive care unit patients and to evaluate the factors related to the 7- and 90-day mortality.
Methods:
Between February 2016 and February 2020, 948 patients without hepatic disease who had 972 episodes of admission to the intensive care unit were retrospectively enrolled and classified as hyperammonemia grades 0 (≤ 80 µg/dL; 585 [60.2%]), 1 (≤ 160 µg/dL; 291 [29.9%]), 2 (≤ 240 µg/dL; 55 [5.7%]), and 3 (> 240 µg/dL; 41 [4.2%]). Factors associated with hyperammonemia and the 7- and 90-day mortality were evaluated by multivariate logistic regression analysis and Cox regression analysis, respectively. Kaplan-Meier survival curves for the 7- and 90-day mortality were constructed.
Results:
The independent risk factors for hyperammonemia were male sex (odds ratio, 1.517), age (0.984/year), acute brain failure (2.467), acute kidney injury (1.437), prothrombin time-international normalized ratio (2.272/unit), and albumin (0.694/g/dL). The 90-day mortality rate in the entire cohort was 24.3% and gradually increased with increasing hyperammonemia grade at admission (17.9%, 28.2%, 43.6%, and 61.0% in patients with grades 0, 1, 2, and 3, respectively). Additionally, non-hepatic hyperammonemia was an independent predictor of the 90- day mortality in intensive care unit patients.
Conclusions
Non-hepatic hyperammonemia is common (39.8%) and associated with the 90-day mortality among intensive care unit patients.

BACKGROUND: It is getting more difficult to involve appropriate investigators in clinical trials. Knowing what investigators want from sponsor initiated clinical trials would help industry cooperate with investigators more efficiently. This study aims to describe the incentives for investigators choosing to participate or not and perform well in sponsored clinical trials. METHODS: Investigators who have participated in GSK sponsored clinical trials were interviewed face-to-face or through e-mail using the standardized questionnaire. Investigators were asked to choose five items and determine the ranking or those five items. RESULTS: Questionnaires answered by 122 investigators were collected. The top three incentives were "Academic merit" (108, 88.5 %), "Expectation of treatment potentially helpful to patient" (101, 82.8 %), and "Access to new treatments" (92, 75.4 %). The disincentives and the factors affecting an investigator's performance were analyzed separately because of the different questionnaire between investigators for medicine and vaccine. Investigators for medicine choose as disincentives "Insufficient time" (43, 61.4 %), "Difficult protocol" (41, 58.6 %), and "Adverse event concerns" (41, 58.6 %). Vaccine investigators pointed out "Limited support staff" (41, 78.8 %), "Insufficient time" (40, 76.9 %), and "Difficult blood sampling" (333, 63.5 %) as disincentives. Factors adversely affecting an investigator's performance showed similar results to those of disincentives. CONCLUSION: Investigators focused on academic curiosity and patients and insufficient time mostly inhibits them from participating and performing clinical trials. Our results would help industry cooperate with investigators more efficiently, finally making companies perform clinical trials more effectively.

Background/Aims:
Acute-on-chronic liver failure (ACLF) is a widely recognized concept in which acute decompensation (AD) in patients with cirrhosis results in organ failure and high short-term mortality. On the other hand, few studies reflecting the various etiologies of cirrhosis are available. This study examined the clinical features of patients with hepatitis C virus (HCV)-related ACLF.
Methods:
Between January 2005 and December 2018, 109 HCV-related cirrhosis patients hospitalized for AD (ascites, hepatic encephalopathy, gastrointestinal hemorrhage, and bacterial infection) were enrolled for ACLF defined by the European Association for the Study of the Liver (EASL).
Results:
ACLF developed in 35 patients (32.1%) on admission. Eight, eight, and 19 patients had ACLF grades 1, 2, and 3, respectively. The 28-day and 90-day mortality rates were very low (2.7% and 5.4%, respectively) in patients without ACLF and very high (60.0% and 74.3%, respectively) in those with ACLF. In patients with HCV-related ACLF, compared to previous studies on hepatitis B virus-related ACLF and alcohol-related ACLF, the prevalence of liver failure was very low (17.1%), whereas that of kidney failure was very high (71.4%). Compared with all other prognostic scores, the Chronic liver failure Consortium Organ Failure score predicted the 90-day mortality most accurately, with an area under the receiver operator characteristic of 0.921.
Conclusions
HCV-related ACLF has unique clinical characteristics distinct from hepatitis B virus-related and alcohol-related ACLF. ACLF defined by EASL can be useful for predicting the short-term mortality in HCV-related cirrhosis.
