Background and Objectives: This study aimed to analyze risk factors for positional vertigo (PV) and the influence thereof on daily life and subjective quality-of-life (QoL). Subject and Methods: A cross-sectional study was conducted using data of the 2010 Korea National Health and Nutrition Examination Survey. The study population consisted of 1,274 individuals aged >40 years for whom complete dizziness-related data were available. Blood and urine tests were performed, and nutritional intake, QoL, and subjective health status were measured using a questionnaire. The associations between PV and blood/urine test data and nutritional intake were evaluated via multiple logistic regression analysis. Results: A history of PV within the previous year was reported by 98 individuals (7.7%). Advanced age and female gender were both significantly associated with such a history. Serum hemoglobin, creatinine, and triglyceride levels correlated significantly with a history of PV. Carotene, vitamin A, and vitamin B2 intakes were significantly lower in individuals with PV. Multivariate analysis revealed that only age was significantly associated with a history of PV (p=0.003). Although subjective health status score was not significantly lower in subjects with PV, subjective impairments in mobility, self-care, the performance of usual activities, and anxiety/depression were more prominent in individuals with PV. A fall history and limitations of activity were also significantly higher in individuals with PV (p<0.001 and p=0.003, respectively). Conclusions: Age was a risk factor for PV, which affected most QoL parameters, fall frequency, and the performance of normal activities.

This study was carried out to compare UCP2 polymorphism, dietary habits, and obesity index in normal and obese university students. The survey was carried out using self-questionnaires collected from the 126 normal and 60 obese university students. The results are summarized as follows. Breakfast was skipped in 43.7% of normal and 49.3% of obesity students and it appeared obese students eat faster than normal students. The percentage of weight control experience were 49.2 and 71.0 in the normal and obese students, respectively. Blood levels of lipid profiles(triglyceride, LDL cholesterol, and HDL cholesterol), hemoglobin, AST and ALT were anaylzed. In UCP2 genes, the frequency of deletion homozygote(DD) was 71.5%, heterozygote(DI) was 26.9% and insertion homozygote(II) was 1.6%. Plasma levels of triglyceride, total cholesterol, LDL cholesterol, and HDL cholesterol of normal students were 79.06, 172.25, 100.86 and 57.03 mg/dl, and those of obese students were 93.06, 173.22, 101.22 and 54.39 mg/dl, respectively. Blood parameters were in normal range in both group. Plasma triglyceride, total cholesterol and LDL cholesterol levels of obese students were higher than those of normal students. On the other hand, plasma HDL cholesterol levels of obese students were lower than those of normal students. Plasma levels of AST and ALT were in normal range in both group. However, AST and ALT levels of obese students were higher than that of normal students. Thus, it was recommended for them to have a nutritional education program to improve their dietary and living habits for obese students’health. Nutritional education program should also be organized practically and systematically.

Importance: Deaths due to neonatal calf diarrhea are still one of the most critical problems of cattle breeding worldwide. Determining the parameters that can predict diarrhea-related deaths in calves is especially important in terms of prognosis and treatment strategies for the disease. Objective: The primary purpose of this study was to determine mortality rates and durations, survival status, and predictive prognosis parameters based on vital signs, hematology, and blood gas analyses in neonatal diarrheic calves. Methods: The hospital automation system retrospectively obtained data from 89 neonatal diarrheic calves. Results: It was found that 42.7% (38/89) of the calves brought with the complaint of diarrhea died during hospitalization or after discharge. Short-term and long-term fatalities were a median of 9.25 hours and a median of 51.50 hours, respectively. When the data obtained from this study is evaluated, body temperature (℃), pH, base excess (mmol/L), and sodium bicarbonate (mmol/L) parameters were found to be lower, and hemoglobin (g/dL), hematocrit (%), lactate (mmol/L), chloride (mmol/L), sodium (mmol/L) and anion gap (mmol/L) parameters were found to be higher in dead calves compared to survivors. Accordingly, hypothermia, metabolic acidosis, and dehydration findings were seen as clinical conditions that should be considered. Logistic regression analysis showed that lactate (odds ratio, 1.429) and CI^- (odds ratio, 1.232) concentration were significant risk factors associated with death in calves with diarrhea. Conclusions and Relevance: According to the findings obtained from this study, the determination of lactate and Cl^- levels can be used as an adjunctive supplementary test in distinguishing calves with diarrhea with a good prognosis.

A free-range wild raccoon dog (Nyctereutes procyonoides) was rescued with cachexia. Physical examination revealed generalized hyperkeratosis and alopecia typical of scabies as well as hypothermia (35.6℃). The patient was obtunded and severely dehydrated (10%). Hematological parameters included a low packed cell volume (PCV; 15%) and hemoglobin concentration, leukocytosis, and hypoglycemia. A blood smear revealed different subtypes of hypochromic leptocytes, indicating a regenerative response against severe anemia. This case was initially tentatively diagnosed as a severe anemia due to chronic external bleeding presumed to be caused by scabies-induced skin injuries. Darbepoetin alpha (DPO), iron dextran, and fluralaner were administered at the initial presentation, and supportive care including oxygen supplementation, warming, and nutritional support was provided. However, on day 5, the PCV dropped to 5.9% presumably caused by rapid rehydration due to drinking water ad libitum. DPO was boosted on days 5 and 6 along with daily iron dextran. On day 21, the PCV had recovered to 19.8%, and a blood smear evaluation showed a strong regenerative response. This case shows that even if severe anemia occurs in a raccoon dog, it can be managed with an appropriate response. In particular, since the rehydration rate due to food intake is faster than the hematopoietic response rate of raccoon dogs, the PCV may decrease rapidly in the early stage of treatment; therefore, diagnostic examination and additional medical management for hematopoiesis are necessary.

Purpose: This study investigated the associations between intermediate hyperglycemia (IH) and increased body mass index (BMI), abdominal obesity (AO), high-sensitivity C-reactive protein (hs-CRP), and leptin levels in Korean adults. Methods: The participants were 248 adults (≥ 19 years) who understood the purpose of the study, had no cognitive impairment, and were able to communicate. Physical examinations, BMI, AO measurements, and blood tests were performed. Data were analyzed using the t-test, chi-square test, Pearson correlation coefficients, and multiple logistic regression analyses. The risk factors for IH were predicted after adjusting for BMI, waist circumference (WC), age, hs-CRP and leptin levels, education, and economic status. Results: WC, hs-CRP and leptin levels, and age were higher in the IH group than in the non-IH group. According to the multiple logistic regression analysis, the factors affecting IH prevalence were WC, hs-CRP, leptin, and age. AO (male, WC ≥ 90 cm; female, WC ≥ 85 cm) exhibited an adjusted odds ratio of 5.45 for IH. IH was 2.43 times higher in those with hs-CRP > 3 mg than in those with hs-CRP < 1 mg. As leptin levels increased, the odds ratio for IH increased by 3.05 times. IH was 8.07, 8.79, 18.42, and 35.33 times more common for those in their 30s, 40s, 50s, and ≥ 60 years of age, respectively, than those 19-29 years old. Conclusion: This study provides evidence that interventions for AO should be included in IH management programs. Identifying the predictive factors for IH may contribute to the early detection of type 2 diabetes mellitus.

This study aims to explore the effect of combined stimulation consisting of relaxation-inducing scent and high-concentration oxygen on psychological/physiological responses. The cerebral blood flow responses and arousal that occur when oxygen concentration is controlled under the same scent conditions were observed. The experiment's scent was lavender oil (relaxing scent), and the oxygen concentrations were normal (21%) and high (30%). The experiment involved 12 male adults repeating a 5-minute rest period and a 5-minute stimulation period. The hemoglobin (HbO) concentration was extracted using the Beer-Lambert law to observe cerebral blood flow responses. Arousal was assessed using a 5-point scale questionnaire. A paired t-test was used to compare the two stimuli (lavender +21%, lavender +30%). Results reveal that HbO concentration in the frontal lobe increased, whereas arousal decreased at lavender +30% vs. lavender +21%. These results suggest that adding high-concentration oxygen to scent stimulation can induce more brain activation and relaxation.

This study was conducted to investigate the effect of probiotic from pine needle microbes on growth performance, blood characteristics, carcass traits and economy of pigs. One hundred eighty pigs (L${\times}$Y${\times}$D, average body weight=75 kg) were grouped and housed with 15 animals per pen for 3 replications per each treatment. The ingredients and pine needle microbes mixed and fermented on anaerobic condition for 10 days to make the fermented diet. The basal diet was substituted with 0 (CON), 3 (T1), 5 (T2) and 10% (T3) of fermented diet, the pigs were fed for 42 days and slaughtered at the end of the trial to measure the carcass traits. Crude protein concentration of fermented diet on 10 day was higher (p<0.05) than that of on 0 day, while crude fiber concentration and pH were lower (p<0.05). The supplementation of fermented diet did not affect on growth performance and feed intake. Hemoglobin concentration of whole blood in T3 was higher (p<0.05) than that of CON, and hematocrit concentrations in CON and T1 were higher (p<0.05) than that of T2 and T3. The concentration of platelet was higher (p<0.05) in T1 than in T2 and T3. The CON had higher (p<0.05) total cholesterol, LDL-cholesterol and triglycerides concentrations than the treatments, whereas lower (p<0.05) HDL-cholesterol concentration. Carcass weight and dressing in T1 and T3 were higher (p<0.05) than those of CON and T2. The backfat thickness was higher (p<0.05) in CON and T2 than in T3. The carcass grade and economy improved by supplementation of fermented diet compare to CON. In conclusion, the supplementation of fermented diet using probiotics from pine needle microbes could improve health and meat quality and reduce the feed cost of pigs.

The objective of this study was to investigate the effects of L-carnitine on growth performance, organ weight, biochemical parameters of blood, heart and liver, and ascites susceptibility of broilers at different ages reared under a low-temperature environment. A total of 420 1-d-old male Ross 308 broilers were randomly assigned to two dietary treatments with fifteen replicates of fourteen broilers each. Treatment diets consisted of L-carnitine supplementation at levels of 0 and 100 mg/kg. At 11-d of age, low temperature stress was used to increase ascites susceptibility. Blood, heart and liver samples were collected at different ages for analysis of boichemical parameters. The results showed that, there was no significant difference in growth performance with L-carnitine supplementation, but the mortality due to ascites was significantly decreased. Dietary L-carnitine supplementation significantly reduced heart index (HI) and ascites heart index (AHI) on d 21, lung index (LUI) on d 35 and liver index (LI) on d 42. The broilers fed diets containing L-carnitine had significantly lower red blood cell counts (RBC), hemoglobin (HGB) concentration and hematocrit (HCT) on d 42. Dietary L-carnitine supplementation significantly reduced malondialdehyde (MDA) content of heart tissue on d 21 and 35, and significantly increased total superoxide dismutase (T-SOD) and Glutathione peroxidase (GSH-Px) activity of the heart on d 21 and 42. L-carnitine supplementation significantly reduced serum triglyceride (TG) content on d 28 and 35 and serum glucose (GLU) on d 35 and 42, and significantly increased serum total protein (TP) and globulin (GLO) content on d 42. L-carnitine supplementation significantly enhanced liver succinodehydrogenase (SDH), malic dehydrogenase (MDH) and $Na^+$-$K^+$-ATPase activity on d 28, and tended to reduce the lactic acid (LD) level of liver on d 35 (p = 0.06). L-carnitine supplementation significantly reduced serum uric acid (UA) content on d 28, 35 and 42. Based on the current results, it can be concluded that dietary L-carnitine supplementation reduced organ index, red blood cell counts and hematocrit, enhanced antioxidative capacity of the heart, enhanced liver enzymes activity involved in tricarboxylic acid cycle, and reduced serum glucose and triglyceride. Therefore, it is suggested that L-carnitine can potentially reduce susceptibility and mortality due to ascites.

This study investigated the effects of dietary rumen-protected L-tryptophan (TRP) supplementation (43.4 mg of L-tryptophan kg^-1 body weigt [BW]) for 65 days in Hanwoo steers on muscle development related to gene expressions and adipose tissue catabolism and fatty acid transportation in longissimus dorsi muscles. Eight Hanwoo steers (initial BW = 424.6 kg [SD 42.3]; 477 days old [SD 4.8]) were randomly allocated to two groups (n = 4) of control and treatment and were supplied with total mixed ration (TMR). The treatment group was fed with 15 g of rumen-protected TRP (0.1% of TMR as-fed basis equal to 43.4 mg of TRP kg^-1 BW) once a day at 0800 h as top-dressed to TMR. Blood samples were collected 3 times, at 0, 5, and 10 weeks of the experiment, for assessment of hematological and biochemical parameters. For gene study, the longissimus dorsi muscle samples (12 to 13 ribs, approximately 2 g) were collected from each individual by biopsy at end of the study (10 weeks). Growth performance parameters including final BW, average daily gain, and gain to feed ratio, were not different (p > 0.05) between the two groups. Hematological parameters including granulocyte, lymphocyte, monocyte, platelet, red blood cell, hematocrit, and white blood cell showed no difference (p > 0.05) between the two groups except for hemoglobin (p = 0.025), which was higher in the treatment than in the control group. Serum biochemical parameters including total protein, albumin, globulin, blood urea nitrogen, creatinine phosphokinase, glucose, nonesterified fatty acids, and triglyceride also showed no differences between the two groups (p > 0.05). Gene expression related to muscle development (Myogenic factor 6 [MYF6], myogenine [MyoG]), adipose tissue catabolism (lipoprotein lipase [LPL]), and fatty acid transformation indicator (fatty acid binding protein 4 [FABP4]) were increased in the treatment group compared to the control group (p < 0.05). Collectively, supplementation of TRP (65 days in this study) promotes muscle development and increases the ability of the animals to catabolize and transport fat in muscles due to an increase in expressions of MYF6, MyoG, FABP4, and LPL gene.
