Background:
The purpose of the present study was to assess the daily protein uptake and its relationship with sarcopenia, as defined by the Asian Working Group for Sarcopenia (AWGS), among elderly patients with hip fractures.
Methods:
Forty-seven elderly patients with hip fractures were enrolled in this retrospective observational study. The main outcome measures included protein uptake, muscle mass, and grip strength for sarcopenia in elderly patients. Sarcopenia was diagnosed according to AWGS. Wholebody densitometry was used to measure skeletal muscle mass, and muscle strength was evaluated using handgrip testing.
Results:
Of 47 patients with hip fractures (12 men and 35 women), 37 (79%) patients exhibited insufficient protein intake (range, 0.01-0.588 g/kg/day), and 10 (21%) patients exhibited excessive protein intake (range, 1.215-2.121 g/kg/day). The mean daily protein intake was 56.5 g (range, 7.2–136.0 g). Prevalence of low muscle strength (handgrip strength <18 kg in women and <26 kg in men) was detected in 13 (37%) women and 8 (67%) men (P=0.076). Sarcopenia (lower muscle mass and lower muscle strength) was detected in 9 (26%) women and 6 (50%) men (P=0.119). Although lower protein intake was marginally associated with sarcopenia (P=0.189), it was significantly associated with lower grip strength (P=0.042).
Conclusions
The present study demonstrated that insufficient protein intake in elderly patients with hip fractures was common, and lower protein intake was significantly associated with lower muscle strength.

BACKGROUND: The skin consists of tightly connected keratinocytes, and prevents extensive water loss while simultaneously protecting against the entry of microbial pathogens. Excessive cellular levels of reactive oxygen species can induce cell apoptosis and also damage skin integrity. Propofol (2,6-diisopropylphenol) has antioxidant properties. In this study, we investigated how propofol influences intracellular autophagy and apoptotic cell death induced by oxidative stress in human keratinocytes. METHOD: The following groups were used for experimentation: control, cells were incubated under normoxia (5% CO₂, 21% O₂, and 74% N₂) without propofol; hydrogen peroxide (H₂O₂), cells were exposed to H₂O₂ (300 µM) for 2 h; propofol preconditioning (PPC)/H₂O₂, cells pretreated with propofol (100 µM) for 2 h were exposed to H₂O₂; and 3-methyladenine (3-MA)/PPC/H₂O₂, cells pretreated with 3-MA (1 mM) for 1 h and propofol were exposed to H₂O₂. Cell viability, apoptosis, and migration capability were evaluated. Relation to autophagy was detected by western blot analysis. RESULTS: Cell viability decreased significantly in the H₂O₂ group compared to that in the control group and was improved by propofol preconditioning. Propofol preconditioning effectively decreased H₂O₂-induced cell apoptosis and increased cell migration. However, pretreatment with 3-MA inhibited the protective effect of propofol on cell apoptosis. Autophagy was activated in the PPC/H₂O₂ group compared to that in the H₂O₂ group as demonstrated by western blot analysis and autophagosome staining. CONCLUSION: The results suggest that propofol preconditioning induces an endogenous cellular protective effect in human keratinocytes against oxidative stress through the activation of signaling pathways related to autophagy.

BACKGROUND: The shortage of human hearts for allotransplantation makes xenotransplantation a possible option for controllable organ providers. To detect acute xenograft rejection, invasive biopsy seems inevitable; however, this occasionally results in poor incision wound healing or infection. To date, no method of noninvasive imaging for early detection of xenograft rejection has been established. We hypothesized that ultrasound speckle tracking would better detect xenograft failure than routine left ventricular ejection fractions (EF). METHODS: From August 2013 to July 2015, a total of six cardiac heterotopic xenotransplants (α 1, 3-galactosyltransferase gene-knockout porcine heart) into cynomolgus monkeys were monitored with echocardiography every 3 to 7 days. M-mode and two-dimensional (2D)-EF measurements and myocardial strain analyses were performed. Cardiac xenograft pathology was reviewed from the immediate postoperative biopsy, as well as the necropsy. RESULTS: Myocardial speckle tracking analysis was feasible in all six cases. The longest survival was 43 days. Only one pathology-proven immunologic rejection occurred. Cardiac xenograft failure appeared as two types: a dilated pattern with decreased EF or a myocardial-thickening pattern with preserved EF. Both antibody-mediated rejection (n=1) and sepsis-induced myocardial dysfunction (n=2) revealed decreased radial or circumferential strains, but normal-range EF. Xenograft functional decline was significant with respect to radial or circumferential strain (P=0.028), but not to conventional M-mode or 2D-EFs (P=0.600, P=0.340, respectively). CONCLUSIONS: Radial and circumferential strains were significantly decreased in both types of xenograft failure, regardless of EF. Further studies are warranted to correlate the strain analysis and immunopathological details.

BACKGROUND/AIMS: To evaluate the diagnostic value of contrast (SonoVue(R)) enhancement ultrasonography (CEUS) and to compare this method with computed tomography (CT) and magnetic resonance imaging (MRI) in evaluating liver masses. METHODS: CEUS (n=50), CT (n=47), and MRI (n=43) were performed on 50 liver masses in 48 patients for baseline mass characterization. The most likely impression for each modality and the final diagnosis, based on the combined biopsy results (n=14), angiography findings (n=36), and clinical course, were determined. The diagnostic value of CEUS was compared to those of CT and MRI. RESULTS: The final diagnosis of the masses was hepatocellular carcinoma (n=43), hemangioma (n=3), benign adenoma (n=2), eosinophilic abscess (n=1), and liver metastasis (n=1). The overall diagnostic agreement with the final diagnosis was substantial for CEUS, CT, and MRI, with kappa values of 0.621, 0.763, and 0.784, respectively. The sensitivity, specificity, and accuracy were 83.3%, 87.5%, and 84.0%, respectively, for CEUS; 95.0%, 87.5%, and 93.8%, respectively, for CT; and 94.6%, 83.3%, and 93.0%, respectively for MRI. After excluding the lesions with poor acoustic sonographic windows, the sensitivity, specificity, and accuracy for CEUS were 94.6%, 87.5%, and 93.3%, respectively, with a kappa value of 0.765. CONCLUSIONS: If an appropriate acoustic window is available, CEUS is comparable to CT and MRI for the diagnosis of liver masses.

Melatonin affects diverse physiological functions through its receptor and plays an important role in the central nervous system. In the present study, we compared immunoreactivity patterns of arylalkylamine N-acetyltransferase (AANAT), an enzyme essential for melatonin synthesis, and melatonin receptor type 1B (MT2) in the spinal cord of young adult (2~3 years) and aged (10~12 years) beagle dogs using immunohistochemistry and Western blotting. AANAT-specific immunoreactivity was observed in the nuclei of spinal neurons, and was significantly increased in aged dog spinal neurons compared to young adult spinal neurons. MT2-specific immunoreactivity was found in the cytoplasm of spinal neurons, and was predominantly increased in the margin of the neuron cytoplasm in aged spinal cord compared to that in the young adult dogs. These increased levels of AANAT and MT2 immunoreactivity in aged spinal cord might be a feature of normal aging and associated with a feedback mechanism that compensates for decreased production of melatonin during aging.

BACKGROUND AND OBJECTIVES: The purposes of this study are 1) to investigate the relationship between resting baseline Pd/Pa, determined by the ratio of the pressures proximal (Pa) and distal (Pd) to the target lesion before, inducing hyperemia and fractional flow reserve (FFR) and 2) to identify a resting baseline Pd/Pa range that might reliably preclude the need for hyperemic induction. SUBJECTS AND METHODS: A total of 622 pressure wire data sets obtained from intermediate stenotic lesions were analyzed. RESULTS: There was a good linear relationship between resting baseline Pd/Pa and FFR (r=0.746, p<0.001). Receiver-operating characteristic curves of the resting baseline Pd/Pa with FFR < or =0.80 as the reference variable showed an area under the curve of 0.89 (95% confidence intervals 0.863-0.914, p<0.001) with a diagnostic accuracy of 82.3% when the resting baseline Pd/Pa was < or =0.92. These results showed that certain cutoff values can reliably predict FFR, whether positive or negative. The resting baseline Pd/Pa >0.95 (n=257, 41.3%) had a negative predictive value (NPV) of 98.1% and a sensitivity of 97.3%. the resting baseline Pd/Pa < or =0.88 (n=65, 10.5%) had a positive predictive value (PPV) of 96.2% and a specificity of 99.8%. These were consistent regardless of coronary vessel, lesion location, lesion length, or degree of stenosis. CONCLUSION: In intermediate lesions, the resting baseline Pd/Pa was linearly related to FFR. A certain range of the resting baseline Pd/Pa values had an excellent NPV with high sensitivity or excellent PPV with high specificity for determining the lesion significance.

PURPOSE: To document post-excision recurrence rates for epidermal cysts of the foot and ankle by location. MATERIALS AND METHODS: The authors retrospectively reviewed epidermal cysts confirmed histologically by excisional biopsy in 37 patients (male 20, female 17) from 2004 to 2011. Cyst locations and sizes were analyzed and preoperative and postoperative pain levels were compared using a visual analogue scale (VAS). Rates of recurrence and patient satisfaction levels were also measured. RESULTS: Epidermal cysts occurred most commonly on the 1st toe (15 cases, 40.6%), followed by the ankle (7 cases, 18.9%), 2nd toe (6 cases, 16.2%), 3rd toe (4 cases, 10.8%), 4th toe (1 case, 2.7%), 5th toe (2 cases, 5.4%), and heel (2 cases, 5.4%). Average cyst size in 35 cases was 15.5x15.0x7.9 mm. VAS reduced from 6.5 preoperatively to 1.0 postoperatively. Cysts recurred in 7 cases (18.9%); on the 1st toe in 5 and on the 2nd toe in 2. Thirty patients (81.0%) were very satisfied with treatment results, 2 patients (5.4%) were satisfied, and 5 (13.5%) were not satisfied. Recurrence occurred in 4 cases, and in one of these cases the cyst recurred after second excision. CONCLUSION: The excision of epidermal cysts in the foot and ankle area was found to have an 18.9% recurrence rate. To achieve good results, the precise location of cysts should be determined by imaging study before excision, and cysts must be excised completely.

BACKGROUND/AIMS: The purpose of this study was to estimate the prevalence of Barrett's esophagus (BE) and its association with reflux esophagitis (RE) and peptic ulcer disease detected by free charge endoscopy which was covered by the National Health Insurance at a secondary care hospital, and to compare the results of the biopsy of BE with that of cardiac intestinal metaplasia (CIM). METHODS: A total of 4,002 patients underwent endoscopy from March 2010 to December 2012. BE was diagnosed if there was histologically proven specialized intestinal metaplasia, and CIM was diagnosed if intestinal metaplasia was accompanied with chronic gastritis. RESULTS: Four hundred twenty four patients underwent endoscopic biopsy, and the prevalence of BE was 1.0% (42/4,002). The mean age and the proportion of males in BE were significantly higher than those of the rest of study population, and BE had slight tendency related to RE than the rest of study population. CIM was observed in 34 patients and BE and CIM showed similar results, regarding age, sex and association with RE. The mean length of endoscopic Barrett's mucosa of BE group was 9.2+/-5.1 mm, and it was similar to that of CIM. CONCLUSIONS: The prevalence of BE in the secondary care hospital was not low, and old age and male sex were significantly associated with BE. Because BE was observed in about 10% of biopsied patients and CIM was observed in a similar percentage with BE, the precise targeted biopsy is warranted and the biopsy method should be reestablished through the large prospective study of multiple secondary care hospitals.

The combination of coronary arteriovenous fistula to the coronary sinus (CS), dilatation of the entire length of coronary artery, coronary aneurysm and persistent left superior vena cava (PLSVC) is very rare. We present the case of a 63-year-old female admitted for dyspnea on exertion, orthopnea, and facial edema. Echocardiography detected a giant coronary artery with shunt flow, dilated CS and PLSVC and a coronary angiography reaffirmed these findings. The calculated ratio of pulmonary blood flow to systemic blood flow by cardiac catheterization was 1.53. After multidisciplinary review considering old age, hypoactivity due to underlying Parkinsonism and relatively small amount of shunt flow, medical therapy was chosen. The patient remained asymptomatic for 10 months after discharge without intervention.

PURPOSE: A medical disaster assistance team from our hospital was sent to the Haiti earthquake for 7 days of medical support. METHODS: We analyzed the characteristics of patients who visited our field clinic at the scene during the subacute period after the disaster. RESULTS: We treated 120 patients over 4 days, including two patients during the preparatory period. Most patients had visited a clinic in the second half of the period. Internal medicine and pediatrics were associated with the chief complaints of most patients. Acute tonsillitis had the largest number of patients(24.6%), followed by skin infections (9.2%), contusions and sprains(8.4%), and gastric ulcers (8.4%). Most of the medications were for conservative management(68.3%). CONCLUSION: During the subacute period after the earthquake, most patients had secondary injuries, such as wound complications and complications from air and water pollution, rather than direct injuries from the earthquake. We recommend that more medical preparation than surgical preparation is required during subacute periods after an earthquake.
