Ten dogs were enrolled in this study: two healthy dogs, two obese dogs without other medical issues and six obese dogs with underlying diseases including pemphigus, chronic active hepatitis, hyperadrenocorticism, narcolepsy, otitis media and heartworm infection. Pyrosequencing of the 16S rRNA gene to explore the gut bacterial diversity revealed that distal gut bacterial communities of samples from patients with pemphigus, otitis media and narcolepsy consisted primarily of Firmicutes, while the major phylum of the distal gut bacterial communities in patients with chronic active hepatitis and hyperadrenocorticism was Fusobacteria. Proteobacteria were the dominant phylum in heartworm infected obese patients.

The present study compared leptin, adiponectin, and thyroid hormone concentrations in normal and obese dogs, and evaluated the association between leptin and adiponectin concentrations and thyroid function. The serum leptin, adiponectin, thyroid-stimulating hormone (TSH), total thyroxine (tT4), free thyroxine (fT4), triiodothyronine (T3), and cortisol concentrations were measured in 18 normal dogs (body condition score [BCS]: 4-5/9) and 16 obese dogs (BCS: 8-9/9). Leptin and T3 concentrations were higher in the obese group than the normal weight group (p < 0.01 and p < 0.05, respectively). In both groups, the T3 and leptin concentrations were correlated (r = 0.370, p < 0.05), as were the TSH and fT4 and adiponectin concentrations (r = -0.373, p < 0.05 and r = 0.369, p < 0.05, respectively). In the normal weight group, the TSH and fT4 concentrations were correlated with the adiponectin concentrations (r = -0.528, p < 0.05 and r = 0.482, p < 0.05, respectively). The results of the present study suggest that leptin and T3 concentrations are significantly higher in obese dogs than normal weight dogs, and the serum T3 and leptin concentrations are positively correlated.

An 11-year-old obese dog was referred for a liver mass. Cytologic examination revealed vacuolated hepatocytes with mild pleomorphism. A partial liver lobectomy was performed. On histopathologic examination, the mass was diagnosed as hepatocellular carcinoma composed of hepatocytes with clear vacuoles. These findings were consistent with clear cell hepatocellular carcinoma (CCHCC). The CCHCC is a rare subtype of hepatocellular carcinoma in dogs, and clinical features are poorly defined. This is the first report on the cytological, histological and clinical aspects of CCHCC, suggesting that obesity and hyperlipidemia are potential risk factors for CCHCC in dogs.

As with humans, overweight or obesity is a major health concern in the companion animal population. A cross-sectional questionnaire-based survey of dog owners attending primary small animal veterinary practices from different areas in Chuncheon, Kangwon province, Korea was undertaken to explore the relationships between socioeconomic and other relevant risk factors associated with canine obesity. In addition, the author was to estimate the prevalence of obesity compared to published literatures for dogs. Owners were asked about dog age, neuter status, feeding habits, dog exercise, household income and owner age. The body condition score (BCS) of the dogs was also assessed. Multivariable binary logistic regression was used to assess the association between BCS and potential risk factors controlling for confounding variables, using odds ratios (OR), 95% confidence intervals (CIs). A total of 275 dogs (136 males and 139 females) aged 1-12 years (mean age $5.6{\pm}3.7$ years) were surveyed in 2013. Of these, 46.9% of dogs (n = 129) were classed as an ideal body shape (BCS = 3), 30.9% (n = 85) were overweight (BCS = 4), 8.4% (n = 23) were obese (BCS = 5) and 13.8% (n = 38) were underweight (BCS = 1 or 2). Neutered males and spayed females had the highest prevalence of obesity (43.4% and 33.9%); intact females had the lowest prevalence of obesity (31.6%). In univariable model, risk factors associated with canine obesity are multifactorial and include owner income, owner age, age of dog, neuter status, frequency of feeding per day, frequency of snacks and consultation with veterinarian on dog's weight. In final multivariable logistic regression model, dogs whose owners reported no consultation with veterinarians for weight management were significantly more likely to be obesity than ideal (OR = 7.6, 95% CI, 4.2-13.8; p < 0.0001). This study showed a high prevalence of obesity in domestic companion dogs. Since this was a cross-sectional study with small samples, the association of canine obesity with risk factors warrants more research. To the author's best knowledge, this is the first Korean study on dog body condition and obesity.

The survey was conducted in July first to 15th, among 463 elementary school students, 4th grade to 6th grade in Chonj. The subjects were 252 male and 211 female students. The mean age of the subjects was 9.8 year The percent of relative body weight of the subjects compared to Korean standard was 100.1%, it almost matched to Korean standard. The percent of relative body weight in male students was 100.4%, where as the female's was 99.7%. Thirty six percent of the subjects have breakfast irregularly. The reason skipping breakfast were 'no appetite' 50.5%, 'get up late' 35.8%,' no delicious food' 18.2%. The reason skipping breakfast was significantly different by sex and obese index. The frequency taking snack was significantly different by sex, 34.6% of female subjects took snack more than twice per day, while 16.7% of male subjects did it. The most frequently taking snack were fruits, the points was 4.0 of 5.0. Ramyun, Sundai were taking more frequently among males than females. Females took fruits more frequently than males. Hot dog, ice cream ,and chocolate intakes were significantly different by obese index. The most preference of snack were fruits and ice cream in all subjects. The preference of ramyun, hamburger, egg, chicken, dried squid, milk, peanut, and soft drink were higher in males than in females. Biscuit, ice cream, and chocolate preference were significantly different in obese index.

As Korea is moving toward multicultural society, the number of Muslim, whose religion has a great influence on diet-related behaviors, is increasing in Korea. Since the number of immigrants from Indonesia ranks within top ten in Korea and Indonesia is one of the most representative Islamic countries in Asia, understanding the diet-related behaviors and food preferences of Indonesians is needed. This study was conducted to investigate diet-related behaviors, factors affecting the diet-related perceptions, and food preferences of the Indonesians. The subjects included 500 Indonesians dwelling in Jakarta, Indonesia. About ninety % of the subjects in this study were Muslims. They did not eat pork and dog meat for religious reason and they practiced fasting during Ramadan period. Indonesians avoided pineapple, durian, and hot foods during pregnancy and usually ate vegetables and fruits after birth, which seemed to be due to sociocultural influence. Among the subjects, 21.5% were obese and major health problems reported were hypertension and hyperlipidemia. Their preference for fried food items might have contributed to health problems. Subjects had meals mostly at home (2.3 times/day) and dined out occasionally (1.2 times/week) at Indonesian restaurants (56.6%) or family restaurants (21.0%). In conclusion, Indonesians had home-based and native food-oriented dietary life with strong religious and sociocultural influence on food choices. Further research on specific nutrient intake analysis is needed to better understand and to improve dietary life of Indonesians in Korea.

This study was conducted to evaluate whether plasma homocysteine levels were related to obesity or its contributing factors (e.g., lipids, insulin, glucose, glucagon, and fructosamine) in dogs without systemic diseases such as diabetes or renal failure. For achieving our study goal, 100 client-owned dogs without systemic diseases were enrolled in this study. Fasting glucose concentration; lipid profile (i.e., total triglycerides [TG], total cholesterol [TC], highdensity lipoprotein cholesterol [HDL-C], and low-density lipoprotein cholesterol [LDL-C]); and fructosamine, insulin, and glucagon levels were determined. The dogs were subdivided by the body condition score (BCS). The median levels of homocysteine were considerably higher in obese dogs than in lean and normal dogs. Interestingly, not only was homocysteine positively associated with the level of HDL-C, but also found to have a significant positive association with TG, TC, plasma glucagon levels, and fructosamine. In contrast, LDL-C, fasting glucose and insulin did not show any association with homocysteine. The findings presented, suggest that elevated levels of homocysteine may play a biological role in obesity in dogs.
